Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a stacking tray pool device in which trays of a certain size in which a large number of articles and the like are stored side by side are stacked and can be placed on a pool conveyor. Regarding

(Prior Art) Conventionally, in a flow work in which a tray in which articles such as a hermetically sealed package filled with contents are stored side by side is sterilized through a sterilizing device by a carry-in conveyor and then discharged from a carry-out conveyor. If a delay occurs between the processes in which trays are continuously sent, the trailing trays have no place to go and the flow work is stopped.

In order to eliminate such a problem, generally, a pool section for waiting in a state where trays are arranged in parallel or stacked is provided to deal with the problem, and these pool sections are provided for each process.

However, if such a pool portion is provided for each process, the space for this becomes large, and therefore the equipment becomes large, so the equipment cost also becomes high.

Therefore, there is a well-known device in which a stacking device in which trays are stacked and a shredding device are separately arranged and the two devices are connected by a pool conveyor of a stacking tray to reduce the space.

Also, as a device for cutting the tray from the top and bottom,
There are known ones such as 56-22263 and Japanese Patent Publication No. 58-48268.

(Problems to be Solved by the Invention) However, in the above-described well-known and publicly-known ones, stacking and cutting are performed by completely different devices, and stacking improves the conventional defects to some extent in terms of space. As the stacking was scattered around the people, it was unavoidable that the production efficiency was lowered, and there was a demand for further space reduction.

In view of this, the present invention provides a pool portion for making trays stand by by stacking them close to the stacking / disassembling device of the trays, and when performing a process such as sterilization, removes one by one from the device and disassembles them. To solve the drawbacks of the prior art by providing a tray pool device that can immediately supply the next stacking tray from the pool conveyor to the stacking / collapsing device at the end of crushing. It was made for the purpose.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides at least one of a tray carry-in conveyor and a carry-out conveyor arranged toward a stacking / shredding device for trays, and a tray on the conveyor. It is characterized in that pool conveyors capable of supplying stacking trays to the stacking and collapsing device at a height position where they do not come into contact with each other are provided in a stacked form, and the stacking trays can be placed on this pool conveyor.

(Operation) With the above-described configuration, the stacking tray is always placed on the pool conveyor in a standby state, and when the tray of the stacking / disassembling device of the tray is disassembled and there is no more tray in the device, the next stacking tray is immediately released. Can be supplied.

(Example) Hereinafter, the present invention will be described with reference to the examples shown in FIGS. 1 to 5.

The pooling device for stacking trays according to the present invention includes, for example, at least one of the tray carry-in conveyor 3 and the discharge conveyor 4 which are arranged with the stacking / shredding device 2 of the tray 1 in between. A pool conveyor 5 is provided in a stacked manner at a height not contacting the tray 1 on the tray 4, and the stacking tray 6 can be placed on the pool conveyor 5.

The stacked tray 6 is a stack of a plurality of trays 1 stacked on top of each other, and in the embodiment shown in FIG. 1, three stacked trays 6 are shown.

A pool conveyor 5 that can be driven in the opposite direction to the conveying direction is provided above the carry-out conveyor 4, and a plurality of stack trays 6 can be placed in a row on the upper surface of the conveyor 5. ing.

The carry-in conveyor 3 and the carry-out conveyor 4 in the illustrated embodiment are configured such that the tray 1 is placed and carried from the carry-in conveyor 3 to the carry-out conveyor 4, and between the two conveyors 3 and 4, for example, Tray 1 as shown below
Is provided with a stacking / shredding device 2, and the upper surface thereof serves as a conveyor 7.

Elevating means 8 having a driving means such as a hydraulic cylinder built therein is provided on the lower surface of the conveyer conveyor 7, and the elevating means 8 is formed so as to be higher than the upper surface of the conveyer conveyor 4 at the maximum rise.

A frame body 9 serving as a guide for the stacked trays 6 is provided outside the elevating means 8, and a claw 11 for supporting the tray 1 and a claw 11 for supporting the tray 1 are provided on a portion of the frame body 9 corresponding to the upper part of the elevating means 8.
A supporting means 10 including a hydraulic cylinder 12 for driving 11 is provided, and the claws 11 alternately operate with the lifting and lowering of the lifting and lowering means 8 to pinch the trays 1 one by one to stack or stack the trays 6. It is designed to be cut down.

In addition, in this embodiment, two claws 11 are provided, two on each side for a total of four.
A single rod provided equidistant from the center of rotation of a lever 13 connected to the rod tip of the hydraulic cylinder 12.
It is fixed to a shaft 16 which is the same as the shaft of the lever 15 via 14 and 14.

Therefore, when the hydraulic cylinder 12 is actuated to extend, the lever 13 rotates to pull the rods 14 and 14 together, and the pawls 11 and 11 rotate to pinch the tray 1 on both sides. Then, the tray 1 is held at that position.

 Next, the operation of the above embodiment will be described.

As shown by the arrow A on the left side of FIG. 1, one tray 1 is sent from the carry-in conveyor 3 to the upper surface of the carry conveyor 7, and when it is lowered to the same height as the carry-out conveyor 4, the tray 1 becomes 1
In the case of one sheet, it is directly carried out to the carry-out conveyor 4 and discharged to the next step. The trays 6 stacked from the pool conveyor 5 are transferred from the right side of FIG. When it is sent, as shown in FIG. 5 (a), the elevating means 8 ascends to raise the conveyor 7 to the same height as the pool conveyor 5.

Then, when the hydraulic cylinder 12 of the supporting means 10 is operated in the extending direction, the lever 15 is moved through the lever 13 and the rod 14.
A claw 11 coaxial with the pinch clamps the tray 1 of the bottom stack. As a result, the trays 1 stacked on top are at the bottom and the claws 11
And is positioned on the conveyor 7 as shown in FIG. Next, as shown in FIG. 2C, the hydraulic cylinder 12 of the supporting means 10 is operated to be contracted to remove the claw 11 from the tray 1.

When the elevating means 8 is lowered from this state by the height of one sheet of the tray 1, the stacking trays 1 are also lowered, as shown in FIG.

When the second tray 1 from the bottom comes to the position of the claw 11, the hydraulic cylinder 12 is again actuated in the extending direction to hold and hold the stack tray 6 above this, as shown in FIG. become.

Next, the elevating means 8 is further lowered until the bottom tray 1 is placed and the upper surface of the upper conveyer conveyor 7 is aligned with the same upper surface position as that of the carry-out conveyer 4, and as shown in FIG. Only one tray 1 remains on the conveyor 7.

As a result, the tray 1 on the carrying conveyor 7 is carried to the carry-out conveyor 4 and sent to the next step.

Hereinafter, by repeating the same operation, the stacked trays 1 can be sequentially cut.

In the above, the case of crushing is explained, but in the case of stacking, the reverse operation is performed and the trays 1 can be stacked one by one from bottom to top.

Therefore, the tray 1 is always supported by either the elevating means 8 or the supporting means 10, and in the case of stacking or breaking down, the tray 1 is alternately raised and lowered and pinched.

In this case, in the pool conveyor 5 according to the present invention, a plurality of stacking trays 6 having an appropriate height by stacking as described above are always prepared and placed for a line so that the stacking / shredding device can be immediately used when necessary. It is possible to supply.

It should be noted that the tray stacking / collapsing device to which the present invention is applied has been described with reference to FIGS. 1 to 4, but this is an example and is not limited to this embodiment. It is also possible to share the conveyor with the pool conveyor.

〔The invention's effect〕

As described above, the present invention, at least one of the tray carry-in conveyor or the carry-out conveyor arranged toward the tray stacking / collapsing device, stacks at a height position that does not contact the tray on this conveyor. A pool conveyor that can supply stacking trays to the shredding device was provided in a stacked form, and the stacking trays could be placed freely on this pool conveyor. In addition to being able to supply, it is possible to pool a large number of stacking trays for stacking and breaking of trays in a narrow space, making it possible to make the entire line compact equipment and improve production efficiency. Moreover, there is an effect that the equipment cost can be reduced.
