This fallen goods G are spread around at the specific position and the distribution thereof becomes uniform in the specific position.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is intended to prevent irregularly shaped items, such as flexible noodles, from being biased in the recesses of a conveyor or in a container on a conveyor. It relates to a device for modifying and achieving uniformity within said recess or container.

[Conventional technology]

An example of a device for uniformizing soft items such as noodles in the recesses of a conveyor in order to shape them before hardening processes such as drying or frying is as described in Japanese Patent Publication No. 59-13854. There is something. This prior art rotates a stirrer consisting of a central protruding part that protrudes downward and a crown gear-shaped peripheral part facing downward on its outer periphery to make the product uniform.

[Problem to be solved by the invention]

However, according to the above-mentioned prior art, the peripheral edge of the crown gear 2 descends and bites into the item, so that the item is made uniform by the central protrusion inside this peripheral edge, but between the inside and outside of this peripheral edge. It becomes difficult to move items. For this reason, when the article is largely biased, the peripheral edge part bites into the biased article, so that it may be difficult to sufficiently eliminate the biased condition.

Therefore, the present invention makes use of the flexibility of the food to grab the food, lift it once, bring the food upward to the center of a predetermined position on the conveyor, and then drop the food to the center of the predetermined position. The purpose is to correct the position of the items and to make the distribution of the items uniform by using the falling blade.

[Failure to solve the problem]

The present invention provides a picking device that includes a plurality of fingers whose lower tips are closely spaced and picks an item between them, and an opening/closing drive device that opens and closes these fingers in the picking direction and the opposite direction. An article bias correction device is constructed by connecting and disposing a II unloading J device on the upper side of a conveyor in which a large number of storage portions are formed in a longitudinal direction.

In addition to the above-described configuration, the present invention also provides a spreading device comprising a plurality of fingers whose lower tips are spaced apart to spread the article, and an opening/closing drive device which opens and closes the fingers in the spreading direction and the opposite direction. , above the competition A.,
It can also be arranged on the rear side of the gripping device and connected to the lifting drive.

[Effect]

When the plurality of fingers of the gripping device grasps an article such as a recess of the conveyor and lifts it up, a part of the article is grasped and located in the center of the plurality of fingers, and the part not grasped is elastically deformed by its own weight. The item falls below the gripped portion, and the item as a whole moves to the center. This causes the item to be located above a predetermined position such as a recess. By subsequently opening the fingers, the item will fall to the center of the predetermined location. This dropped item spreads around at a predetermined location due to the impact force of the fall, and its distribution becomes uniform within said predetermined location.

In the bias correction device equipped with the spreading device, when the items dropped at the center of the predetermined position of the conveyor by the fingers of the gripping device are not spread sufficiently, the fingers of the spreading device Each expansion from the center to the periphery makes the item more uniform within a given location. The fingers of this spreader move downward in the closed state to bite into the center of the item, open to spread the item, then rise, close away from the item, and descend again.

〔Example〕

The illustrated embodiment is an example of a bias correction device that uses a gripping device that grabs and lifts items from a conveyor and drops them, together with a spreading device B that spreads items on the conveyor from the center to the outer circumference. be.

An elevating drive device 3 consisting of a cylinder device fixed to a pedestal 2 faces the second side of the conveyor 1, which conveys soft items such as noodles to the right as shown by arrow C in FIG. An elevating member 4 is connected to the elevating drive device 3 (specifically, to the tip of the piston 1 of the cylinder device). 3a is a cover that covers the lifting drive device 3. In the conveyor 1, a large number of recesses 5 for storing articles are formed at regular intervals in the longitudinal direction, and a plurality of recesses 5 are also formed in the width direction of the conveyor 1, and the articles are placed in each of these recesses. 5
and are transported in multiple rows.

Such a conveyor 1 may be replaced by a plurality of containers positioned on the conveyor 5 and containing articles therein, instead of the recesses 5, and furthermore, the articles may be placed on a flat conveyor surface. It may be something that has been placed.

The elevating member 4 extends in the width direction of the conveyor 1, and elevating tubes 6 fixed to both ends of the elevating member 4 are slidably fitted onto a guide shaft 7 erected on the pedestal 2.

In FIG. 2, only one end of the elevating member 4 is shown and the other end is omitted.

This elevating member 4 is equipped with a gripping device. Only one gripping device A is shown in FIG. 2, but in the width direction of the conveyor 1 (left and right direction in FIG. 2),
The number of recesses 5, that is, the same number as the rows of items, are attached to the lifting member 4.

The gripping device A includes four fingers 8 whose lower tips are closely spaced and grips an article between the tips, and an opening/closing drive device 9 which opens and closes these fingers 8 in the gripping direction and in the opposite direction. Consisting of The number of fingers 8 may be 3 trees, 5 trees or more, but in this embodiment it is 4 trees.

As shown in FIG. 3, the opening/closing drive device 9 of this gripping device A includes a cylinder 11 fixed to the elevating member 4, a piston 12 inside this cylinder 11, and a pivot 13 at the outer lower part of the cylinder 11). 4 Hellcranks worn ■
4 and a bottle 1 whose tip is at the end of each crank 14.
5, and an inlet/outlet 19,20 is formed that communicates with the upper chamber 17 and the lower chamber 18 in the cylinder 11 defined by the piston 12, and the air pressure, etc. The piston 12 moves forward and backward by the inflow and outflow of pressure fluid. The upper end of the finger 4, whose lower end is bent inward, is fixed to each arm 14a forming the other end of the hell crank 14.

The inlets and outlets 19 and 20 of the opening/closing drive device 9 are connected to a fluid pressure source via a fluid control valve (not shown), and the first chamber and the royal room of the lifting drive device 3 are also connected to a fluid pressure source via a fluid control valve. connected to the source.

Each of these fluid control valves (especially the direction switching valve ↑) is a well-known electromagnetic valve, and when the gripping device A descends, the finger 4 descends in an open state, and in the descending state, the finger 4 closes, and then in the closed state. The sequence control circuit is designed to sequentially perform a series of operations in which the gripping device A is raised by 1 and the fingers 8 are opened in the raised state. Further, the series of operations described above is carried out in one of the recesses 5 of the conveyor I which is intermittently driven.
This is done to synchronize with the pinch action. 19a and 20a shown in FIG. 1 are flexible pressure-resistant hoses that connect the opening/closing drive device 9 and the fluid control valve. Note that when the conveyor 1 is driven continuously rather than intermittently, the pedestal 2 is connected to the conveyor 1.
It is sufficient that the gripping device A performs the above-described operation when the gantry 2 moves in synchronization with the conveyor 1 by moving forward and backward in the advancing direction of the conveyor 1 .

Further, an elevator drive device 23 is disposed on the rear side of the elevator drive device 3 (downstream side of the conveyor 1) in line with the pedestal 2, and the lower end of the elevator drive device 23 is provided with the elevator member 23. Similarly to 4, an elevating section +: A24 is connected, and a plurality of spreading devices B, like the grasping device A, are attached to this elevating member 24 in the width direction of the conveyor 1. This spreading device B has the same structure as the gripping device A described above. The spreading device 13 shown in FIG. 1 therefore consists of a finger 28 identical to the finger 8 to the gripping device and an opening/closing drive 29 identical to the opening/closing drive 9 to the gripping device.

However, the flexible ports 19a and 20 connected to the entrances and exits 19 and 20 of the opening/closing drive device 29 constituting this expanding device B
a is connected to a fluid control valve that is sequence-controlled so that when the spreader B is lowered, the finger 28 is lowered in the closed state, opened in the lowered state, raised in the open state, and closed in the raised state. be done. Further, the lowering limit of the spreader B is slightly higher than the vertical limit of the gripping device A, and the positions shown in FIG.
This is the vertical limit. The different elevation limits are realized by adjusting the height of the elevation drive device 3.23 relative to the pedestal 2.

In addition, since the elevating part +A'4.24 is designed to rise and fall synchronously, one of the elevating and lowering drive devices 3.23 is omitted and used in common, and the elevating and lowering members 4 and 24 are integrated, and a grasping device is attached to this. A and an expanding device B can also be installed. In this case, the height of the spreading device B may be made slightly higher than the gripping device.

However, as in the embodiment, the lifting devices 3 and 23 and the lifting member 4
, 24 individually, it is possible to operate the gripping device A and the spreading device B at mutually different timings and at different lifting distances.

Next, the operation will be explained.

First, the operation of the gripping device will be explained with reference to FIG. When the recess 5 in which the article G of the conveyor 1 is accommodated reaches below the gripping device A (FIG. 4(a)), the lifting member 4 is lowered by the lifting drive device 3, and the lifting member 4 is integrated with the gripping device 10. A descends. The center of the recess 5 is set in advance so as to be located below the center position of the gripping device, and at this time, the finger 8 is lowered in an open state by the opening/closing drive device 9, and the tip of the finger 8 is lowered into the recess. The item G in the recess 5 is inserted into the item G (Fig. 4 (bl), and then the tip yiii of the finger 8 is closed by the opening/closing drive device 3 to grasp the item G. The article G, which was in the position, is brought closer to the center by the gripping action of the fingers 8 (FIG. 4(C)).

Next, as the elevating unit 4 is raised by the elevating drive device 3, the gripping device A also rises while gripping the article G. Due to the dirt, the outer part of the finger 8 of the item G is moved below the lower end of the finger 8 due to its flexibility, and the item G as a whole is moved to the center (FIG. 4(d)). After decreasing η1 to a predetermined height, the fingers 8 are opened by the opening/closing drive device 9 and the article G is dropped into the recess 5. At this time, the item is dropped into the center of the recess 5, and the impact of the fall causes the flexible item to spread and be distributed within the recess 5 (Fig. 4(e)). Thereafter, the gripping device A is lowered again by the lifting drive device 3 while the fingers 8 remain open.

After said falling of the article G, the conveyor 1 moves one pitch intermittently until the next recess 5 is under the gripping device A. In addition, item G
Of course, the falling height is adjusted in advance depending on conditions such as the type of article G and its flexibility.

The articles G that have been processed by the gripping device arrive under the spreader B by the movement of the conveyor 1.

In this case, the finger 28 is lowered by the lifting drive device 23 while being closed, and its tip enters into the article.
The fingers 28 are then opened by the opening/closing drive 29 to spread the article outward from the center of the recess 5. therefore,
Due to the action of the gripping device, items that are centered in the recess 5 and are not sufficiently distributed outwards are distributed evenly within the recess 5 by the spreading device B. However, if the product has properties that can be made uniform only by the operation of the gripping device A, it is not necessary to undergo processing by the spreading device B.

After the fingers 28 are opened as described above, they are raised by the lifting drive device 23, closed by the opening and closing drive device 29, and then lowered again. At this time of descent, the articles that have been processed by the above-mentioned "kokumi" device are placed below the spreader B, and are subjected to the next processing by the spreader B.

In the operation of the spreading device B into such a gripping device, the fingers 8.28 have their tips bent inward in the shape of a "<" character, so that they are suitable for picking up the article and pushing the article away from the center. It is also suitable for expansion.

Although the above embodiment used a cylinder device as the elevating drive device 3.23, other known devices and power transmission means can be used instead as long as the device can raise and lower the elevating members 4, 24. Of course. Furthermore, although the finger 8.28 is made of a thin plate and is elongated over its entire length, depending on the type of item, the lower end may be made wider, for example, to be able to handle a base-like item. Moreover, it is also possible to use the device exemplified as the prior art in place of the spreading device B or in combination with the spreading device C.

〔Effect of the invention〕

As explained above, according to the present invention, the flexibility of the article is used to grasp and lift the article with the plurality of fingers of the gripping device, and then the article is dropped. As the items are lifted up and brought to the center, and further dropped, they spread from the center to the periphery, correcting the unevenness of the items and distributing them at predetermined positions.

Furthermore, by using the spreading device in combination, the fingers will forcibly even out items that could not be made sufficiently uniform by the gripping device alone, so that the unevenness of the items can be sufficiently corrected, and in the subsequent process. processing can be made smoother.
