DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for weighing and sorting articles, in particular, scallops, shrimp, and other fish and shellfish, which is optimal for weighing and sorting one by one.

[0002]

2. Description of the Related Art Recently, it has been widely practiced to sort out seafood such as scallops and shrimps one by one, and ship a certain number of seafood of each class in a box. However, conventionally, for measuring the weight of such fish and shellfish one by one, as shown in FIGS. 31 and 32, for example, a belt conveyor continuously disposed on the upper transfer path of the belt conveyors 184 and 185. The weighing mechanisms 124 and 125 are disposed below the 122 and 123, and articles stored in the storage unit 104, such as scallops, are transferred to the belt conveyor 122.
In the course of transporting 123, the weighing mechanism 1
The weight is measured by the belt conveyors 122 and 123, and the common belt conveyor 10 of the next process is obtained from the belt conveyors 122 and 123.
7, a plurality of gate plates 108a, 10a driven in accordance with the measurement results weighed by the weighing mechanisms 124, 125.
8b, 109a, 109b,... Are selectively provided according to the measurement results of the weighing mechanisms 124, 125 on the upstream side.
There has been known an apparatus which sorts by rotating around 0b or not rotating. However, according to such a device, some fish and shells are likely to roll, and may roll on the weighing belt conveyors 122 and 123 and fall outward. Further, in the above-described conveying device, the articles on the belt conveyor 107 are transferred to the gate plate 1.
08a, 108b, 109a, 109b,..., So that flexible products such as fish eggs or shrimp cannot be sorted. That is, there are restrictions on the properties and shapes of the objects to be conveyed and weighed. In addition, the weighing mechanism, for example, the load cell is disposed below the belt conveyors 122 and 123, so that the structure is complicated. In addition, when the goods to be handled are fish and shellfish, especially the regular feeding must be performed frequently. , Belt conveyors 184, 185, 122,
There is a drive system 102 and a weighing mechanism 125 on the back side of 123,
Cleaning them is difficult in order to keep them from splashing water. In this connection, the maintainability is poor. In addition, since articles are removed from the belt conveyor 107 on both sides, the articles cannot be arranged in more than two stations, and the processing capacity is limited. Also, V-shaped article locking pieces are installed on the belt conveyors 184 and 185, and the articles are locked and conveyed by these locking pieces, but a large amount of articles are stored in the storage unit 104. In this case, a plurality of articles are simultaneously transferred to one locking piece. Therefore, in order to perform correct one-by-one weighing, it is necessary to have an operator resident in each row and remove unnecessary items downward by a large number of people.

On the other hand, a mechanism is also provided in which air suction means is provided in place of the gate plates 108a, 108b and the like, and the air suction means sucks an article and automatically discharges the article. If there is no flat plate portion, suction cannot be performed, and for example, it cannot be applied to chestnuts and the like. That is, versatility is poor.

On the other hand, it is conceivable to use a bucket conveyor instead of a belt conveyor, supply the weighed articles to the buckets, and sort the articles according to the weighed result. However, there are the following problems.

FIG. 33 shows a conventional bucket conveyor-based transport apparatus in which a bucket is mounted between a pair of chains and horizontal and vertical transport is circulated by these chains.

[0006] In the transfer device 1, gear units 4, 5, 6, and 7 are supported in a rectangular base 3 formed by angles 2. The rotational force of a motor (not shown) is transmitted to a pulley 8 provided on the gear device 4 via a belt, and a driving force is transmitted to the conveying means 9 via the gear device 4.

As shown in FIG. 34, the conveying means 9 comprises a pair of two-chain chains 10 and 11.
The chain chains 10, 11 are provided with a pair of shaft locking portions 12, 12, 13, 13 at predetermined intervals. On the inner side of these two-chain chains 10, 11, plates 14, 15 are respectively arranged adjacent to the chains.

On the other hand, the bucket 16 has an opening on one side and a substantially trapezoidal cross section, and a shaft mounting part is provided at each end of both side walls 16a and 16b arranged in parallel with the two-chain chains 10 and 11. Bosses 17a, 17b, 17c, and 17d are formed.

The bucket 16 having such a boss is formed.
The transport direction G indicated by the arrow in FIG. 33 and FIG.
The long shaft 18 is inserted through the bosses 17b and 17d on the front side, and both ends of the long shaft 18 are inserted up to the two-chain chains 10 and 11 and locked by the shaft locking portions 12 and 13, respectively. ing. On the other hand, the boss 17a on the rear side with respect to the transport direction G,
A short shaft 19 is inserted through 17 c, and both ends of the short shaft 19 are locked to the plates 14 and 15.

In this manner, the buckets 16 are continuously set on the gantry 3 at predetermined intervals. When goods are transported by a series of buckets 16 set on the gantry 3,
Articles are sequentially put into the bucket 16 in a horizontal state from a position above the gantry 3. By arranging the ends 14a and 15a of the plates 14 and 15 at a place where goods are collected, the short axis 1 of the bucket 16 passing therethrough is arranged.
9 is removed from the plates 14 and 15, the bucket 16 is rotated about the other long axis 18 as a fulcrum, and the contents are dropped downward.

[0011] By the way, in such a conveyor device using a bucket conveyor, the bucket 1 that has become empty after the end of the conveyance.
Then, the carriage 6 runs on the lower transfer path of the gantry 3 while being suspended by the long axis 18, further moves upwardly in the vertical direction, and near the end of the upward movement, the short axis is moved onto the plates 14 and 15 by appropriate means. 19
Is reset.

Therefore, in the conventional bucket conveyor, the vertical movement of the bucket 16 is a suspension posture in which the opening is oriented in the horizontal direction, and it is not possible to insert an article in a portion moving in such a posture. . Therefore, there is a limitation on a work space or the like using the bucket conveyor.
Further, in the above-described transport device, the short axis 19 is
In order to slide on the upper part, a lubricating means for the sliding part is required, and the apparatus is complicated. Further, if the hydraulic oil used in the lubricating means adheres to the inside of the bucket, there is a problem that the commercial value of the conveyed articles is impaired.

In a conventional bucket conveyor as shown in FIGS. 33 and 34, as described above, articles can be put into the bucket 16 only by the horizontal transfer path. Assuming that one by one is weighed by the weighing mechanism and one by one, sorting may be performed according to the weighed value on the downstream side from the charging position. As described above, the ends 14 of the plates 14, 15
a, 15a, all buckets 16 are now in FIG.
As shown by 4, when one of the supports is removed, the article is rotated around the front shaft 18 and the article is dropped downward. The article is sorted and rotated according to the weighing result. This is not possible with this conventional bucket conveyor.

On the other hand, there is a walking beam method as a transport means instead of the bucket conveyor. However, there is a problem in that when articles are transported by such a method, the transport speed is limited, and in that case, the articles jump off during the transport.

[0015]

This makes it possible to easily increase the processing capacity without deteriorating the commercial value due to the adhesion of lubricating oil, etc., to easily wash the product, and to easily discharge the product from the bucket. It is intended to provide equipment.

It is supplied to the supply end of the second chain conveyor. This second
The chain conveyor transfers the scallops one by one in a plurality of rows, and injects the scallops one by one into a plurality of product weighers from the discharge end.
One scallop is received in the article receiving portion made of the first plate of the article weighing machine, and the weight of one scallop is weighed by the upper load cell connected thereto. The second plate is extruded from a short side of the second plate rising through the gap between the first plate and the scallops received on the first plate, and is disposed to face the second plate. One scallop is supplied to the bucket in the vertical transfer path of the bucket conveyor of each row of the plurality of bucket conveyors.

Since the bucket rotatably supported by the support shaft always has an opening facing upward in a suspended state,
Articles can also be loaded in the vertical transfer path, and the loaded articles are stored in the space defined by the front and rear walls. Since the guide piece abuts on and is guided by the vertical guide member when it is thrown in the vertical transfer path, it is possible to prevent the article from dropping due to swinging. Moisture adhering to the article is removed downward from the slit during transport. The removal of the stored items from the bucket is performed by exciting an electromagnetic solenoid corresponding to the weighed result, engaging a guide piece of the bucket with an engaging member attached to the electromagnetic solenoid, and pivoting the bucket on a spindle.

Thus, the weight of the scallops currently received can be weighed via the first plate by the weighing machine connected to the first plate. Water adhering to the scallop drops downward through the space between the first plate members. On the other hand,
The second plate member performs a predetermined closed-loop motion by driving the lever crank mechanism through the interval between the plurality of first plate members. When the second plate member passes through the interval between the first plate members, the weight is measured in the article receiving portion. The product can be discharged from the product receiving portion and supplied to a bucket when the product moves in a predetermined stroke while pressing the product. Thereafter, the plurality of second plate members move according to a predetermined stroke, and when the plurality of first plate members again pass through the interval between the plurality of first plate members and are supported from above and have already weighed items in the same manner as described above, the next plurality of second plate members are supported. Can be discharged to a bucket.

As described above, articles can be efficiently weighed, for example, scallops or shrimps one by one, and can be smoothly discharged to the bucket. The first plate members are arranged at intervals. In addition, since the article receiving section can be formed in a shape corresponding to the article to be weighed, for example, a belt type is not suitable for easy rolling, but depending on the shape of the article receiving section of the first plate material. It is possible to reliably weigh fish and shellfish of any shape, and to smoothly discharge the fish and shellfish to the bucket.

Further, since the load cell for weighing the articles received by the article receiving section is disposed above the article receiving section, it is easy to spray water from above the first and second plate members during cleaning. The load cell can be cleaned without adversely affecting the load cell. In addition, since the fixed article receiving section can receive and weigh the articles in a stationary state, the accurate value can be stably weighed, and the second sheet material can be quickly discharged from the bucket into the bucket. Can be.

Although the article weighing / sorting apparatus 100 according to one embodiment of the present invention is configured as described above, in this embodiment, the weighing / sorting apparatus 100 is used as a scallop weighing / sorting apparatus. Have been. Hereinafter, a weighing / sorting apparatus 1 for sorting such seafood (scallops) of the same kind by weight.
The operation of 00 will be described.

The stocker V stores a large amount of scallops M. In the first chain conveyor 130, the electric motor 13
6 drive chain 1 via the chain 137
34 is driven, so that each slat S mounted between the chains 145 on both sides moves in the direction indicated by the arrows in FIGS. 2 and 3 and is now located at the lower end and in the recess 1
The slat 148 having 48a has a scallop M at its recess 148a, depending on its size and length of the recess 148a.
A plurality of, for example, five pieces are transferred upward in one horizontal line. The normal recess 14 between these slats 148, 148
In the case of the flush slat S having no 8a, since the inclination angle of the chain conveyor 130 is large, the slat S slips, and FIG.
Only the scallops M accommodated in the recess 148a are transferred upward as shown in FIG. These are supplied to the guide chute 140 from the upper end of the chain conveyor. The guide chute 140 runs along each of the runways A, B, C, and D. However, the guide chute 140 does not align with the first chain conveyor 130 on the upstream side.
The exits a, b, c and d of each of the runways A, B, C and D are provided at a predetermined distance to one side, and are connected to the second chain via auxiliary chutes 161, 162, 163 and 164. Since the scallops M are discharged from the outlets a, b, c and d one at a time at the lower end of the chain 169 of the second chain conveyor 150, since the scallops M are aligned with the respective chains 169 of the conveyor 150, It heads towards the element 141 at a relatively low speed.

As described above, the scallops M are distributed and supplied to the respective rows of the second chain conveyor 150 one by one from the guide chute 140, where they are locked by the V-shaped elements 141 of each row. Then, it is supplied again upward together with the element, and the item weighing machine 9 downstream from the upper position.
0 is supplied.

In the article weighing machine 90, the lever crank mechanisms 91 and 91 'rotate the shaft 98 at a constant speed, whereby the shaft 101 fixed to the crank plate 99 rotates at a constant speed along the locus E. When the shaft 101 rotates 45 degrees from the phase shown in FIG. 9, it assumes the position shown in FIG. Lever 95
Swings around the axis 94 from the position shown in FIG. The lever 97, via its pivot point 96, connected to it, assumes the position shown in FIG. 11, so that the discharge plate 110 fixed to its left end also assumes the position shown. Further rotation by 45 degrees, that is, rotation by 90 degrees from the phase of FIG. 9, takes the position shown in FIG. 12, the lever 95 further swings to the right around the shaft 94, and the lever 97 moves to the right. At the same time, the left end moves downward. Therefore, the discharge plate 110 fixed to this end takes the position shown in the figure.

Further rotation by 45 degrees takes the position shown in FIG. 13, and in this phase, the lever 95 changes its moving direction to the left and swings. At the same time, the lever 97 moves to the left, but the left end further falls downward, and the discharge plate 110 fixed thereto takes the position where it falls downward. Further rotation 45 degrees, ie 180 degrees from the rotation phase of FIG. 9, takes the position shown in FIG. 14, in which the lever 95 swings to the left around the axis 94 and is thus pivotally connected to it. The lever 97 is also moved to the left, and the discharge plate 110 fixed to the left end falls further downward. When rotated further 45 degrees, the lever 95 assumes the position shown in FIG. 15, and the lever 95 swings further to the left around the shaft 94, so that the lever 97 connected thereto also swings to the left, and both are slightly swung. Start to rise upwards. Further rotation by 45 degrees takes the position shown in FIG.
Moves slightly around the axis 94 to the left. As a result, the discharge plate 110 assumes the illustrated position. Further rotation by 45 degrees takes the position shown in FIG. 17, whereby the lever 95 swings greatly around the shaft 94, and this movement also causes the lever 97 to move significantly to the right and both upwardly. Moving. Therefore, the discharge plate 110 also moves greatly in response. When the lever 95 further rotates by 45 degrees, the lever 95 swings largely to the right around the shaft 94, and at the same time, the lever 97 also moves to the right, and the left end thereof largely moves upward. Therefore, the initial rotational phase shown in FIG. 9 is taken.

As described above, the crank plate 99 fixed to the shaft 98 moves along the stroke indicated by the trajectory E by the constant-speed rotation of the shaft 98. 114 is performed, during such a stroke, in a rotational phase as shown in FIG. 12, or on the article receiving portion T formed on the upper side of the weighing plate 168 as the first plate during the stroke. One scallop M is supplied from the upstream second chain conveyor 150.
16 are placed as shown in FIG. Therefore, these three weighing plates 168 are integrated, and are coupled to a pair of weighing coupling plates 106a and 106b extending upward at both ends, and are coupled to the upper ends thereof. At this time, the weight of the scallop M placed on the article receiving portion T is weighed by the load cell 111 that is present. Then discharge plate 11
4 moves along the above-mentioned locus, but the scallop M which is weighed and located in the goods receiving portion T is rotated at a rotational phase between the rotational phases shown in FIGS.
As a result, the scallop M received by the receiving portion T is pushed out as shown in FIGS. 9 and 17. Therefore, as shown in FIG. 9, the vertical portion of the bucket conveyor 20 disposed on the right side is dropped and supplied to one of the buckets 35 being transferred as shown by an arrow f.
In some cases, a guide chute may be provided to ensure this supply.

As described above, one scallops M is supplied to the bucket 35 from the article weighing machine 90. During this process, the next scallops M are already transferred from the second chain conveyor 150 to the article receiving portion T. Although it is supplied and subjected to the weighing and discharging operations as described above, the timing of supply from the second chain conveyor 150 can be the rotation phase as shown in FIG.
In other words, it can be affected by soft landing. That is, the long edge 114 of the discharge plate 114 in the rotation phase shown in FIG.
b receives scallops M from the chain supply conveyor 78,
This gradually descends in response to the above-described stroke, and is thereby gently placed on the article receiving portion T of the weighing plate 107 and stably moved by the load cell 111 by the load cell 111.
Can be weighed, and as the rotational phase further advances, it is pushed out by the short edge portion 114a of the discharge plate 114, and the scallops M are dropped and supplied to the next bucket 35.

The movement timing of the bucket 35 of the downstream bucket conveyor 20 coincides with the supply timing of the scallops M supplied one by one from the second chain conveyor 150 by adjusting the rotation speed of the electric motor 142. The next bucket 35 is surely at the position for receiving the next scallops.

Although the discharge plates in other rows have not been described above, a plurality of rows are provided as described above in this embodiment, and the same operation is performed. In addition, since these rows are operated in synchronization, if four rows are provided as in the embodiment, four scallops M are simultaneously weighed four by four, and each of the buckets 35 of each row arranged in parallel is weighed. Can be supplied at the same time as falling.

The scallops M weighed by the four-row item weighing machine 90 are supplied to the bucket conveyor 20 having four rows.

In the bucket conveyor 20, the electric motor 142
Is driven and five rows of two-row chains 3
3, 33, 33, 33, 33, another gear train 2
Power is transmitted to 4, 25, and 26. Accordingly, four rows of buckets are transported in the direction of arrow F in FIGS. 18 and 19 while being supported between the two double-row chains 33, 33. Eight electromagnetic solenoid devices 64, 64 ...
64 are all in the non-excited state, and the corresponding engaging means 66 are all in the upper position. As described above, the scallop after weighing is transferred to the gear device 2 in the bucket conveyor 20.
One is supplied to the bucket 35 which is transporting the vertical transfer path between the gear 6 and the gear device 23. In this vertical transfer path section, the bucket 35 holds the guide piece 3 as shown in FIG.
7, the curved portions 37a and 37b abut on the vertical guide member 55 to guide the traveling in the vertical direction, so that the posture is kept constant. That is, even if articles such as the scallop are thrown into the bucket 35 in the vertical transfer path, the bucket 35 does not swing. In the embodiment, the scallop put into the bucket 35 is the article weighing machine 9.
The groups are classified into eight groups by 0, and to which group the scallops belong is input to the controller 200 after weighing. The weighed scallops are sorted by weight by the bucket conveyor 20 and stored in groups in a lower container. The sorting operation will be described below.

The group by weight corresponds to any one of the electromagnetic solenoid devices 64. After storing the scallops in the bucket, the travel distance of the double chain 33 until reaching the corresponding electromagnetic solenoid device 64 is calculated by a pulse encoder or the like, and after a predetermined time, the corresponding electromagnetic solenoid device 64 is excited for a predetermined time. It has become so.
When the electromagnetic solenoid device 64 is excited, the actuator 65 and the engagement means 66 in FIG. 27 are in the state of FIG.
The rear wall 3 of the desired bucket 35 that is going to pass immediately below
The engaging portion 71 is disposed forward in the traveling direction of 5d. Therefore, since the bucket 35 travels with the rear wall portion 35d abutting on the engaging portion 71 of the engaging means 66, the bucket 35 rotates counterclockwise about the shaft 51 in FIG. , The scallop contained was the lower collective chute 7
6 and falls into an appropriate position and is stored in a container or the like.

Thereafter, similarly, in the subsequent bucket, the predetermined electromagnetic solenoid device 64 is excited, and the scallop passes through the chute and is stored in a container according to weight. Therefore, scallops are sequentially sorted by weight within a predetermined range and stored in a container or the like.

Further, the bucket 35 after the article is dropped
Is transported with some vibration thereafter, and reaches the engaging portion 85 of the bucket tilting member 77 arranged on the most downstream side. When reaching the engaging portion 85, the guide piece 37 comes into contact with this, and the bucket 35 rotates again. Therefore, the electromagnetic solenoid device 6
Even if 4 does not operate, scallops remaining in the bucket will be reliably discharged at this position.

On the other hand, the bucket containing the items of the weight which does not belong to the above-mentioned eight groups but belongs to the remaining groups passes through all the electromagnetic solenoid devices 64 and reaches this position. , And drop the scallops downward. Therefore, scallops are discharged from all buckets.

When the bucket 35 comes into contact with the bucket tilting member 77 as described above, most of the buckets have been dropped by rotating the scallops. It reaches the tilting member 77 while swinging. Therefore, depending on the pivoting posture of the bucket, a large impact force may be applied to the bucket support, the tilting member, or the two-row chain 33 when the bucket abuts on the tilting member 77. However, since the bucket tilting member 77 is rotatable by the support shaft 83 as described above, when a large force acts on the tilting member 77 from the bucket 35 via the guide piece 37, the tilting member 77
Rotates counterclockwise from the state of FIG. 29 and shifts to the state of FIG.

Therefore, the impact force is absorbed by the rotation,
The breakage of the guide pieces and the like is prevented. After rotating the bucket, the bucket tilting member 77 returns to the lower position again by the urging force of the weight 86.

When the bucket 35 after the article is dropped by the electromagnetic solenoid device 64 reaches the tilting member 77 in a relatively stable posture, when the bucket 35 reaches the tilting member 77 via the guide piece 37, the guide piece 37 is moved. When the force acting on the tilting member 81 via the tilting member 81 is smaller than the biasing force of the weight 86, the tilting member 77 does not rotate. As shown in FIG. 29, the rotary member comes into contact with the tilting member 77 held at the lower position and rotates.

When the bucket 35 has finished transporting the contents, the front wall 35c and the rear wall 35
d returns to the upward inclination, travels from the remaining horizontal transfer path section to the vertical transfer path section and the lower horizontal transfer path section, and the posture is again held by the guide piece 37, and the gear device 26 Is transferred through the vertical transfer path between the gear and the gear device 23.

[0077] The weighing and sorting apparatus 100 for goods according to the present embodiment.
Performs the above-described operation, whereby a large amount of scallops M having different weights are stored in the stocker V in a large amount, and can be sorted by weight into eight predetermined weights. Therefore, it becomes much easier to ship each class of scallops in a box.

Although the article weighing / sorting apparatus 100 according to the embodiment of the present invention operates as described above, the following effects are obtained.

That is, in the first chain conveyor 130, the slats 148 in which the recesses 148a are formed every two sheets are provided.
Is provided, so that the scallops M can be scooped up and transported to the upstream side in an amount matched with the requirement of the next step, and the scallops M almost slip on the slats without 148a in the meantime. Are not transferred upward. Therefore, the driving force of the first chain conveyor 130 can be minimized.

Further, for example, the slats 148 that scoop up articles by arranging them every third sheet can be suitably adapted to transport articles of other shapes by changing the shape of the central recess 148a.

Further, since the number of rotations of the motor 136 is adjustable, even if the arrangement of the slats 148 having the recesses 148a is fixed, it is possible to meet the demands of the next process (the number of scallops supplied per unit time). We can deal with it immediately.

Further, since each slat S is detachably attached to the chain on both sides by two pins 60, the interval between the slats having the concave portions and the number of connected slats can be freely adjusted. In the above-described embodiment, the arrangement of the slats having the recesses is determined according to the size of the fish and shellfish. However, in some cases, the slats having the recesses are provided in consideration of the load of the chain conveyor which is arranged upward and inclined. The interval may be determined.

Therefore, according to the first chain conveyor 130, articles stored in the stocker V at the lower end thereof, for example, scallops can be efficiently transported upward with the upward inclination, and the driving force thereof is minimized. Can be set to

Further, since each slat can be detachably attached to the chain by, for example, the pin 60, the arrangement of the slat having the recess can be changed according to the load or the size of the fish and shellfish to be conveyed, such as the size of the fish and shellfish. Arbitrarily connected by
Alternatively, it can be arranged. The application range of the chain conveyor and the layout design of the driving force can be widened.

In the guide chute 140, the upstream ends of the runways A, B, C and D are arranged in alignment with the first chain conveyor 130 arranged on the upstream side. The discharge ends a, b, c, and d of the runways A, B, C, and D take a position deviated to one side with respect to the upstream end,
Therefore, the second chain conveyor 150 connected thereto and the first chain conveyor 130 on the upstream side are not aligned. With such a configuration of the guide chute 140, it is possible to transfer the single chain single-layer and single-row on the transfer path including the V-shaped elements 141 of each row of the second chain conveyor 150. That is, since the discharge ends a, b, c, and d are arranged so as to be deviated to one side with respect to the upstream end of the guide chute 140, the runways A, B, C,
The inclination angle of D with respect to the horizontal line can be reduced, and therefore, even if the step between the first chain conveyor 130 and the second chain conveyor 150 is large, the inclination angle for sliding can be reduced, and therefore the first inclination angle can be reduced. Scallop guide chute 140 supplied from chain conveyor 130
The speed of the scallop gliding on each runway A, B, C and D in can be smaller, and thus the transport path consisting of the V-shaped element 141 of the second chain conveyor 150 can be fed at a moderate feed rate. It can be supplied and can be transported upward in a single layer / single row. That is, when the upstream chain conveyor is disposed at a large inclination angle and the downstream chain conveyor is also disposed at a large inclination angle as in the present embodiment, the scallops are provided from the former discharge end to the latter supply end. In the case of supply, if the length of the entire apparatus in the horizontal direction is increased, the inclination angle of the guide chute 140 can be reduced, but the installation area of such an apparatus cannot be generally increased. Therefore, in order to reduce the angle, the inclination angles of the first and second chain conveyors 130 and 150 must be increased as shown in the drawing. This is particularly effective when transferring scallops in layers and single rows. Therefore,
According to the guide chute 140, the first chain conveyor 130 and the second
Even if there is a large step between the discharge end of the first chain conveyor 130 and the supply end of the second chain conveyor 150, the sliding speed of the scallops is reduced to increase the upward inclination of the chain conveyor 150. Since it can be supplied to the conveyor 150, it is suitable for supply to the second chain conveyor 150 in a single layer / single row, for example.

In the second chain conveyor 150, since the scallops which have been made into a substantially single layer and single row by the guide chute 140 are received and conveyed, the V-shaped element 1
The scallop can be locked one by one by 41, and therefore, the second chain conveyor 150 can prevent a large number of articles from being simultaneously transferred to the weighing machine 90 downstream.
Therefore, the auxiliary workers to prevent multiple transport of goods are
It is sufficient to have one person with the chain conveyor 150 having a row of conveying paths.

Further, according to the article weighing machine 90, regardless of the shape of the article to be weighed, or to be discharged or supplied, it can be reliably received and weighed. Further, the discharge or supply to the next step can be made smooth. Further, in the weighing machine 90, since the articles are weighed by the suspended load cells 111, the reliability of the weighing can be ensured. In addition, since the load cell 111 is located above, cleaning is easy.

In the bucket conveyor 20, when marine products and the like are transported, regular washing is performed for hygiene. However, since the electric electromagnetic solenoid device 64 is located above the gantry 22, the bucket conveyor 20 uses water or the like. Easy to clean. or,
The processing capacity can be set freely according to the rotational force of the electric motor 142, the number of arrangements of the bucket conveyors, and the like. Also, this motor 1
A variable speed 42 drives the item weighing machine 90, the bucket conveyor 20, and the second chain conveyor 150 by the electric motor 142, so that these can be operated in synchronization.

In the bucket conveyor 20, scallops are loaded in the vertical transport path, but they can be loaded in the upper horizontal transport path, and the loading position can be set appropriately. Therefore, the work space using the bucket conveyor can be diversified.

When the bucket 35 moves from the vertical transfer path to the horizontal transfer path, and vice versa, and when the scallop is dropped, the bucket 35 automatically rotates with the shafts 51 and 51 as fulcrums. And since the rear wall 35d is inclined upward,
No complicated resetting means is required.

Further, since a plurality of slits w are formed in the bucket 35, the water adhering to the articles drops downward from the slits w. The load can also be reduced. Further, even when water is sprayed from above and washed with water, water does not accumulate on the bottom.

Further, since the ribs r are provided, some articles can be prevented from being caught in the slit w, and the frictional force can be reduced so that the articles can be smoothly discharged downward.

Also, since goods are transported in a bucket system,
The nature and shape of the object to be transported are not limited at all, and a wide variety of products can be transported.

Also, in the suspended state, it is rotatable,
In addition, since the front wall portion and the rear wall portion are upwardly inclined, the opening naturally turns upward after discharging the item, so that there is no need for reset means for changing the bucket to the position for receiving the item, and Can be simplified. In addition, since the guide pieces extending substantially vertically are guided and transported by the vertical transport path portion, it is possible to prevent inadvertent rotation at the time of article input without particularly lengthening the bucket in the vertical direction. Further, since there is no sliding portion when transporting the bucket, there is no possibility that the hydraulic oil of the lubricating means adheres to the product, and the product can always be transported in a good state.

The items weighed and stored in the bucket are determined in a predetermined order by activating an electromagnetic solenoid that is excited or de-energized in accordance with the range to which the weight belongs. Can be discharged to the place,
Automatic sorting can be performed within a certain range while being transported, automation is achieved, and the entire apparatus is compact.

When the bucket 35 comes into contact with the bucket tilting member 77 on the most downstream side and a force greater than a predetermined value is applied to the engaging portion 71, the bucket tilting member 77 rotates against the weight 86. Therefore, the impact force can be absorbed by the rotation, so that the support portion of the guide piece 37 can be prevented from being damaged, and the bucket 77 can be rotated in a stable state. .
