Abstract

PURPOSE:To prevent a partition plate from jerkily sliding in the push-out direction by providing a grip finger for gripping the end edge portion of a partition plate on opposite side to the push-out direction when canned goods on the uppermost partition plate are pushed out. CONSTITUTION:A carriage 16 is moved in the direction of an arrow A until an opened grip finger 15 clamps both side spaces 5'a1 of te end edge portion 5'a of the uppermost partition plate 51, and stopped. Subsequently, the grip finger 15 is closed by operation of an air cylinder to grip the end edge portion 5'a. After that, a canned goods push-out device 10 is operated to push out canne goods on the uppermost partition plate 5' in the direction of an arrow A. At this time, as the uppermost partition plte 5' is gripped by the grip finger 15 at rest, the plate will not slide jerkily in the push-out direction. After the completion of pushing- out operation, the carriage 6 is moved in the direction of an arrow B by operation of the air cylinder 19 to transfer the partition plate 5' onto a partition plate transfer device.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a partition plate delivery device, and more specifically, canned goods, usually retort sterilized cans, are stacked in multiple stages via a plurality of partition plates. The present invention relates to a device for feeding out the basket 4 and the partition plate.

(Prior art) Conventionally, retorts for sterilizing canned goods have had a relatively small capacity, the baskets for storing canned goods have been correspondingly small, and the partition plates have also been relatively small. After the canned food has been sent out, the removal of the top partition plate from the basket was mainly done manually.

(Problems to be Solved by the Invention) However, recently, products such as canned coffee drinks are produced in small quantities in large quantities and require retort sterilization.

A type of canned food has appeared.

In this case, for example, a large mat-type retort with a capacity of 10 to 15 tons is used, and several large baskets weighing about 2 tons when filled with canned goods are housed in the retort and the sterilization process is performed.

The partition plates used at this time are also large in size, for example, if they are made of plastic such as polypropylene, the weight of one piece is about 5:9 and the size is about 1200 crn x 125.
0 crnX 6 wn (thickness), and manual extraction is difficult, dangerous, and time-consuming and inefficient. Furthermore, when pushing the canned goods on the top partition board out of the basket, it is impossible to prevent the partition board from sliding in the extrusion direction by holding it down by hand, so a mechanism to prevent the sliding movement is provided. There is a need.

As a mechanical means for taking out, or sending out, a large-sized partition plate from the basket, a delivery device equipped with a vacuum suction cup is used. After the partition plate is suctioned by the vacuum suction cup, the vacuum suction cup is Therefore, it is conceivable to raise and move the partition plate to send out the partition plate. However, in this case, there are problems in that the structure of the delivery device is complicated and therefore the device is expensive, and furthermore, the above-mentioned droplet movement prevention mechanism must be provided separately from the delivery device.

(Objective of the Invention) The present invention is a partition which has a relatively simple structure and which is suitable for sending out large-sized partition plates, and which has both the functions of sending out the uppermost partition plate and preventing the movement of the partition plate. An object of the present invention is to provide a plate delivery device.

(Structure of the Invention) The present invention is a device for feeding out a basket in which canned goods are stacked in multiple stages via a plurality of partition plates, and the device is configured to feed the canned goods through a plurality of partition plates in the uppermost stage. A grip finger grips an edge of the partition plate opposite to the extrusion direction while extruding the canned food, and after the extrusion is completed, the grip finger is moved in the direction opposite to the extrusion direction,
After the carriage for sending the partition plate out of the basket and the movement in the opposite direction are completed, the grip fingers are opened to release the grip, and when the grip fingers return to the original position, the The present invention provides a partition plate delivery device characterized by being equipped with a grip finger opening/closing device for closing the grip fingers and performing the gripping.

(Means for solving the problems, operations, and effects) The device of the present invention can store canned goods on the top partition board.

During extrusion, a grip finger is provided to grip the edge of the partition plate on the opposite side to the extrusion direction, so this grip finger can prevent the partition plate from moving in the extrusion direction. .

In addition, the device of the present invention moves the grip finger that grips the edge in the direction opposite to the extrusion direction, and the carriage sends the partition υ plate out of the basket, and the movement in the opposite direction is completed. After that, the grip fingers are opened to release the grip, and when the grip fingers return to the original position, the grip fingers are equipped with an opening/closing device bB for closing the grip fingers and applying force to the grip. The carriage is sent out of the basket, but the carriage only moves in the horizontal direction, and there is no need to use a vacuum device that moves up and down frequently and is easy to have a complicated configuration. The device may have a relatively simple structure. The grid fins have both functions of sending out the partition plate and preventing movement of the partition plate.

Moreover, since the device of the present invention operates mechanically, it can be suitably used for delivering large-sized partition plates.

(Example) In Fig. 1, Fig. 2, and Fig. 3, 1 is a can delivery device;
Reference numeral 2 designates a partition plate delivery device, and 3 designates a partition plate transfer device that transfers the delivered partition plate to a stacker (not shown).

The canned goods delivery device 1 carries out a large number of canned goods 4 which have been subjected to retort sterilization.

The conveyor device 8 is located between the basket 6 and the belt conveyor device 8, and is operated by a drive mechanism (not shown) that pushes out the cans 4 on the dead plate 9 fixed to the frame and the top partition plate 5' in the direction of the arrow. After the can extrusion device 10 and the extrusion of the cans 4 on the top partition plate ′ onto the dead plate 9 are completed, the bottom plate 6b of the basket 6 is adjusted to the thickness of the partition plate 4 and the height of the cans 4. A lifting ram driven by a hydraulic device (not shown) repeatedly pushes up the partition plate 5' by a height equal to the sum, so that the partition plate 5' at the top level is always located at a slightly higher level than the putting plate 9. It is equipped with 11.

Note that when the canned goods 4 before retort sterilization are pushed out and placed on the partition plate 5 by a can loading device (not shown) into the basket 6, the maximum number of canned goods 4 are placed on the partition plate 5. In order to place the cans 4, the cans 4 are arranged in a staggered manner in a direction perpendicular to the extrusion direction, as shown in FIG.

While the extrusion device 10 is extruding the canned food 4 on the uppermost partition plate 5', the partition plate delivery device 2 is configured to feed the end edge of the partition plate 5' on the opposite side to the extrusion direction (arrow direction). 5
The area 5 / where there is no canned food caused by the staggered arrangement of the canned food 4 at both ends of 'a' (may be near the side end of the central part)
A grip finger 15 is provided to hold the space a1 (hereinafter referred to as the space) in a stationary state and prevent the partition plate 5' from moving in the extrusion direction.

Further, the partition plate sending device 2 includes a grip finger 15.
The carriage 16 is provided with a carriage 16 attached to an end on the side of the basket 6. The carriage 16 has wheels 18 running on a rail 17 extending over the upstream end of the partition plate transition device 3.

In the above device, when the basket 6 is moved by the rollers 7 and stopped at a fixed position in the frame (not shown) facing the dead plate 9, the lifting ram 11 is raised and the uppermost partition plate 5 until its top surface reaches a level slightly higher than the top surface of dead plate 9. Immediately, the carriage 16 moves to a position where the grip fingers 15 in the open state sandwich the spaces 5'a1 at both ends of the edge 5a of the uppermost partition plate 5'. According to the operation based on the signal, the machine moves in the direction of arrow A and stops.

Immediately, based on a signal from a sensor (not shown), the air cylinder 29 operates, and the grip fingers 15 close to grip the edge portion S/a. Thereafter, the can pushing device 10 operates to push out the canned food on the uppermost partition plate 5' in the direction of arrow A. At this time, the uppermost partition plate 5' is gripped by the grip fingers 15 in a stationary state. , so it does not shift in the extrusion direction.

When the extrusion of the canned food 4 is completed, the air 7 cylinder 19 operates based on a signal from a sensor (not shown).
The piston rod 20 moves forward (in this case, extends in the direction of arrow A), and the carriage 16 moves in the direction of arrow B. Therefore, the partition plate 5' gripped by the grip fingers 15
The belt also moves in the direction of arrow B until it is in a horizontal state, reaches above the belt conveyor device 30 on the upstream side of the partition plate transfer device 3, and stops. Immediately, based on a signal from a sensor (not shown), the air cylinder 29 is operated, the grip fingers 15 are opened, and the partition plate 5' falls onto the belt conveyor device 30 and is conveyed in the direction of arrow C.

With the grip finger 15 open, the carriage 16 moves in the direction of arrow A and returns to its original position by the operation of the air cylinder 19, but during this time the lifting ram 11 rises and the carriage 16 moves to the upper position in FIG. Then, the second stage partition plate 5'' rises to the level of the top stage partition plate 5', and the same operation as described above is repeated.
