BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic reversal discharge of a filling material in which a container storing the filling material is inverted and dropped into a guide cylinder to discharge the filling material and automatically fill another container prepared below. Regarding the device.

[0002]

2. Description of the Related Art As an automatic device for reversing and discharging a filling, for example, as shown in Japanese Utility Model Publication No. 3-30338, a measured or arbitrarily determined amount of filling is stored in a container.
The filling in this container is discharged into a can or bag of a separately prepared automatic canning machine or automatic bagging machine to fill it, and the empty container after discharging the filling is automatically collected. Things are known

FIG. 5 illustrates the automatic reversing and discharging device described in the above publication, in which a container 1 containing a filling S is sequentially fed on a carry-in conveyor 2 and a pair of locks are held at the end of the carry-in conveyor 2. After being temporarily stopped by the bars 3 and 4, the locking bars 3 and 4 are operated to send out one by one, hit the edge 5b of the opening 5a of the guide cylinder 5, invert / fall into the guide cylinder 5, and drop. The container 1 is received by a container receiving table 6 including a fixed table 6a and a rotary table 6b.

The fixed table 6a has a filler discharge hole which is slightly smaller than the outer diameter of the container 1 below the guide tube 5, and is slightly larger than the outer diameter of the container 1 at 180 ° opposite position. The rotary table has a container discharge hole, and the rotary table has through holes at equal intervals which are slightly larger than the outer diameter of the container 1, and a container housing cylinder 7 having the same diameter as the through hole, and a drive motor. 6 by 8
It is designed to rotate intermittently every 0 ° (filler discharge hole,
(Container discharge holes, through holes, etc. are not shown).

Then, the container 1 dropped from the guide cylinder 5 enters the container cylinder 7 and is stopped by being stopped at the periphery of the filling material discharge hole of the fixed table 6a. Is effectively discharged, and is charged into the separately prepared container C through the filler discharge hole and the hopper 9. After the filling is discharged, the rotary table 6b is rotated by a predetermined angle and the storage cylinder 7 is moved, so that the empty container 1a is removed from the position of the filling discharge hole, and instead the empty storage cylinder 7 enters the position. Prepare for the next discharge of the filling material S. On the other hand, when the containing cylinder 7 containing the empty container 1a rotates to reach the position of the container discharge hole, the empty container 1a in the containing cylinder 7 is fixed to the fixed table 6a.
It is discharged from the container discharge hole provided in the container through the discharge cylinder 10, and is discharged to the outside by the discharge chute 11 and collected.

[0006]

By the way, in the above-mentioned conventional automatic reversing and discharging device, since the reversing and dropping operations of the container are performed by moving the carry-in conveyor and operating the locking bar, it takes time to enter the container to the reversing position. However, there is a problem in that the reversing operation is not fast and the ability cannot be improved. Also,
Since the container in the guide tube falls naturally, the impact when it is received by the container receiving table is not too large, and in the case of sticky filling, it will not be completely discharged by adhering to the peripheral wall of the container. There was a problem.

The present invention has been made in order to solve the above-mentioned conventional problems, and improves the capacity of the automatic reversing and discharging device for filling materials, and also enables complete discharge of adhesive filling materials. The purpose is to

[0008]

According to the present invention, a container for accommodating a filling material and sent on the carrying-in means is inverted into a guide cylinder.

It is characterized in that drive means for intermittently rotating the means every 180 ° is provided.

The automatic reversing and discharging device for the above-mentioned filling material is
More specifically, a container having a filling material discharge hole that is slightly smaller than the outer diameter of the container at a position below the guide tube, and a container that is slightly larger than the outer diameter of the container at a position above the container discharge means described below. A container receiving table having a discharge hole, container discharging means for transferring the container from the position of the filling discharge hole to the position of the container discharge hole on the container receiving table, and carrying out the container discharged from the container discharge hole Equipped with a container unloading means for inverting the inside of the guide cylinder around the filling material discharge hole.
It is characterized in that it receives a falling container, discharges the filler downward through the filler discharge hole, and discharges an empty container from the container discharge hole.

Further, in the automatic reversing and discharging device for the above-mentioned filling material, preferably, at the bottom of the pair of container accommodating portions,
Each of them is provided with a weight plate that can freely move up and down by a fixed distance, and as a driving means for intermittently rotating the container reversing means at every 180 °, a driving means for unequal speed rotation is used.

[0011]

The container containing the filler and sent on the carrying-in means is temporarily stopped at a predetermined position on the carrying-in means, and then pushed into one of the container accommodating portions of the container inverting means by the container pushing means, and subsequently, When the container inverting means is rotated by the driving means as the container is rotated, and the container inverting means is rotated by 180 ° and stopped, the container is ejected from the container accommodating portion by the inertial force and is inverted and dropped in the guide cylinder. .

When the container receiving table, the container discharging means, the container unloading means, and the like are arranged below the guide tube, the container which falls inside the guide tube reversely falls and collides with the container receiving table and stops. The impact discharges the filling material through the filling material discharge hole, while the empty container after discharging the filling material moves on the same table by the container discharging means and is discharged and collected on the container discharging means from the container discharging hole. .

When the weight plate is provided on the bottom of the container accommodating portion of the container inverting means, when the container accommodating portion stops,
The inertial force of the weight plate is momentarily applied to the container, and the container can be reliably and quickly ejected from the container accommodating portion. Further, when using a drive means that rotates at an unequal speed as the drive means of the container reversing means, for example, if the container reversing means increases in speed at the start of rotation and is suddenly stopped at a 180 ° reversal position The inertial force of the container and the weight plate is increased, and the container can be reliably and vigorously ejected from the container accommodating portion.

【Example】

(Embodiment 1) A first embodiment of the present invention will be described with reference to FIGS. As shown in the figure, the automatic reversing and discharging device of the present invention is fixed to a carry-in conveyor 15 for sequentially carrying in the containers 1 containing the filling S and a horizontally installed rotary shaft 16 so as to be rotatable and rotated at both ends thereof. Symmetrically, a container reversing device 17 including container accommodating portions 17a and 17b, and a container pushing device 18 that pushes the containers 1 on the carry-in conveyor 15 into the container accommodating portions 17a or 17b of the container reversing device 17 one by one. 180 of the container reversing device 17, the control motor 20 for intermittently rotating the container reversing device 17 through the gear box 19 and the rotating shaft 16 at an arbitrary speed every 180 °
A guide cylinder 21 is provided for guiding the container 1 which is turned over and dropped in accordance with the rotation thereof and guided downward.

Further, the automatic reversing discharge device has a filling material discharge hole 22a which is slightly smaller than the outer diameter of the container 1 at a position below the guide cylinder 21, and at a different position from the outer diameter of the container 1. A container receiving table 22 having a slightly larger container discharge hole 22b, and a pair of container storage cylinders 2 at symmetrical positions on both ends.
3a and 23b, with the vertical rotation shaft 24 as the center between the guide cylinder 21 and the container receiving table 22.
From the container receiving device 23 and the container receiving table 22 which rotate intermittently every 80 ° so that the container storage cylinders 23a and 23b alternately stop at positions directly above the filling material discharge hole 22a and the container discharge hole 22b. Empty container 1 discharged below
A carry-out conveyor 25 and the like for receiving and collecting a are provided.

Numeral 30 is a container 1 on the carry-in conveyor 15.
Is a stopper for temporarily stopping the container discharge device 23 at the pushing position.
A motor for intermittently rotating every 0 °, 33 is a hopper installed below the filler discharge hole 22a of the container receiving table 22, and 34 is a container discharge hole 22 of the container receiving table 22.
It is a discharge cylinder attached below b. The container pushing device 18 is composed of a pushing plate 35 having an L-shape in plan view and a pushing cylinder 36 for driving the pushing plate 35. The front surface 35a of the pushing plate 35 pushes the container 1 into the container accommodating portion 17a or 17b. The succeeding container 1 can be stopped from advancing by the side surface portion 35b (shown in phantom in FIG. 3).

Next, the operation of the above-mentioned automatic reversal discharge device will be described. The container 1 in which the filling S is stored and carried in one after another on the carry-in conveyor 15 has a stopper 30 provided at the pushing position.
To stop once. When the push-in cylinder 36 operates, the stopped front container 1 is pushed out at a right angle from the top of the carry-in conveyor 15 by the front surface portion 35a of the push-in plate 35, and is pushed into one container accommodating portion 17a of the container reversing mechanism 17 ( (Shown in phantom in FIG. 3). At this time, the succeeding container 1 is stopped from advancing by the side surface portion 35b of the pushing plate 35.

When the container 1 is pushed into one of the container accommodating portions 17a, the control motor 20 operates to rotate the container reversing device 17 through the rotating shaft 16 at a predetermined speed by 180 ° and then suddenly stop. . With the rotation of the container reversing device 17, the container 1 in the container accommodating portion 17a is also rotated 180 ° and inverted, and when the container reversing device 17 suddenly stops, the inertial force causes the container accommodating portion 17a to pop out, and the container 1 is in the inverted state. Falls inside the guide cylinder 21. The control motor 20 is a servo motor that detects a position and a speed by a detector and controls the rotation. For example, while the container reversing device 17 is rotated 180 °, the speed is increased at the same time as the rotation is started and the container is inverted 180 °. It is possible to arbitrarily set the rotation speed, such as setting to make a sudden stop at the position.

The container 1 falling in the guide cylinder 21 enters the container storage cylinder 23a below, and the container receiving table 22.
And collides with the periphery of the filling material discharge hole 22a and stops. Due to the impact at this time, the filling S in the container 1 is effectively discharged and is filled into the bag F prepared below through the filling discharging hole 22a and the hopper 33. During this time, since the container 1 is in the container storage cylinder 23a, scattering of the filler is prevented.

When the filling S is discharged, the motor 31 is operated to horizontally rotate the container discharging device 23 by 180 ° through the rotary shaft 24. As a result, the container storage cylinder 23a rotates on the container receiving table 22 from the position of the filling material discharge hole 22a to the position of the container discharging hole 22b while keeping the empty container 1a after the filling material is discharged, and the empty container 1a is While sliding on the receiving table 22, it is moved to the container discharge hole 22b. The empty container 1a is discharged downward from the container discharge hole 22b through the discharge cylinder 34 and is collected by the carry-out conveyor 25.

On the other hand, since the container reversing device 17 which has inverted and dropped the container 1 in the container accommodating portion 17a is rotated 180 degrees, the container accommodating portion 17b is now in a position to accept the container 1, Similarly, the pushing device 18 pushes the next container 1. In the container discharge device 23,
This time, the container storage cylinder 23b comes to a position below the guide cylinder 21, and the container 1 falling here is received. Hereinafter, by repeating the same operation, it is possible to continuously and efficiently invert / fall the container, discharge the filling material, and recover the empty container.

(Embodiment 2) Container reversing device 37 shown in FIG.
Is different from the first embodiment in that a weight plate 38 is attached to the bottoms of the pair of container accommodating portions 37a and 37b so that the weight plate 38 can freely move up and down by a dimension l. The weight plate 38 is the container 1
In the container accommodating portion 37a in the position for receiving
The container accommodating part 37b, which is in contact with the bottom of the container accommodating part 37a by its own weight and is rotated by 180 ° and is in the inversion falling position, protrudes downward by a dimension l.

By installing such a weight plate 38 on the bottoms of the container accommodating portions 37a and 37b, the inertial force corresponding thereto is further added to the container 1 which is inverted and dropped, and the container 1 is accommodated in the container accommodating portion 3
7a, 37b overcomes friction and vigorously releases downward, so that the container can be reliably and quickly placed in the container accommodating portion 37.
It is possible to jump out from a and 37b, and it is possible to enhance the impact effect when discharging the filler.

[0024]

According to the automatic reversing and discharging device of the present invention, the operation of pushing the container containing the filling into the container accommodating portion of the container reversing means is promptly performed, and the operation of reversing the container is also performed by the container reversing means. It can be done quickly by rotating 180 °. Also, since the container containing the filling is inverted, the container containing part pops out vigorously, drops inside the guide cylinder, collides with the container receiving table, and stops, so even an adhesive filling can be effectively and surely secured. Is discharged. Furthermore, the empty container can be efficiently discharged and collected by the container discharging means, and the speed and capacity of the device can be greatly increased.
