Description

[Detailed description of the invention] The present invention has a pair of receivers attached to opposite sides of the end of the stacking frame to support the stacking pack members inside, and lifts and lowers the lower end pack member on the receiving claws to pull out the lower end pack member downward. The present invention relates to an individual pick-up device for pack members in which a flexible vacuum suction nozzle is installed below a stacking frame.

Conventionally, in such a device, when the lower end pack member in the stacking frame is pulled out using a vacuum suction nozzle, the upper adjacent pack member is clamped and fixed by a clamp arm that operates in a horizontal plane, and the upper adjacent pack member is removed. A device for preventing continuous release is shown in Japanese Utility Model Application Publication No. 49-144679, but if the height of the pack member (pack or its lid) itself made of a hard plastic film is lower than the planar outline, Difficult to apply.

This means that even if the pack members are provided with reinforcing protrusions to create a slight gap between the stacked pack members, the pack members must be correctly leveled and stacked when loading the pack members into the stacking frame. This is difficult in actual work, as the upper and lower adjacent pack members are often slightly inclined to each other, so the clamp arm fits into the receiving claw side of the lower end pack member supported by the receiving claw and the adjacent pack member above it. This is because a gap may not be formed, and the upper adjacent pack member cannot be prevented from coming out.

The present invention deals with this problem, and even if the pack members loaded in the stacking frame are low in height compared to the flat area,
The purpose is to always be able to reliably perform individual extraction.

In the present invention, auxiliary catch claws 1 are placed at intervals below each catch claw 1.
a, and a clamp arm 2 that rotates in a vertical plane with its upper end as a fulcrum on the opposite side of the stacking frame on the side where the receiver is attached,
The clamp arms are mounted so that the respective pressing surfaces 2a can cooperate to clamp the pack member on the receiving claw and the auxiliary receiving member, and the clamp arms are received with a downward depression formed between the opposing pressing surfaces 2a. A power device is provided that opens and closes approximately symmetrically between a closed position where the lower layer of the stacked pack member on the claw 1 is compressed and deformed and an open position where it is released.
The power unit is configured such that the ends of each of the clamp arms protrude inward from the pressing surface 2a of the clamp arm in the closed position, and rotates both the clamp arms to the closed position only when the vacuum suction nozzle 3 is raised or lowered. The invention is characterized in that it is equipped with a device for controlling.

The figure shows an embodiment of the present invention, in which a stacking frame 6 in which lids (pack members) 5 of packs 4 are to be stacked has the upper ends of angle members 6a provided at the four corners fixedly connected together by beam members 6b. At the same time, a beam 6C is fixed to one opposite side of the lower part, and the stacking frame 6 passes through a base 8 attached to the conveyor frame 7 and is fixed upright thereto via the beam 6C. , the receiving claw 1 and the auxiliary receiving claw 1a arranged slightly below the receiving claw 1 are connected to the beam member 6.
It is fixedly supported by the base 8 at the center of the other opposing side where C is not provided.

The tip of the auxiliary receiving claw 1a is slightly projected inward from the receiving claw 1.

The clamp arms 2 are provided on both sides of each receiving claw 1, and the upper end of each clamp arm is attached to a horizontal shaft 9 provided for each receiving mounting side.
are fixed respectively.

Each side is rotatably supported near both ends by a bearing attached to a base 8, and a fixed arm 11 and a bracket 12 on the base 8 are connected to one end of the horizontal shaft 9 by a cylinder 13. This forms a power device for opening and closing the opposing clamp arms.

At the lower part of the clamp arm 2, there is provided a protruding pressing surface 2a that clamps both sides of the lower end portions of the lids 5 or the stacked pack members stacked in the range H in FIG. 3.

Two vacuum suction nozzles 3 are fixed upright at the tip of the lifting arm 14, and at the base end of the lifting arm 140 there is a lower end of a piston rod of an air cylinder 15 fixed upright on a base 8 and the base 8.
A vertical guide shaft 16 is fixed which freely passes through the shaft.

Therefore, the vacuum suction nozzle 3 can only move up and down between the lowered position shown by the solid line in FIG. 2 and the position shown by the chain line in FIG. .

The vacuum suction nozzle 3 is connected to a vacuum source from the end of its ascent to the end of its descent, and its upper end opening sucks outside air or the pack member, and at the end of its descent, the suction pack member is attached to the conveyor frame 7. As in the conventional case, the nozzle 3 is controlled to be connected to the outside air immediately before being supported by the guide rail 17.

Reference numeral 18 denotes a support rail for the pack member connected to the end of the guide rail 17. As shown in FIG. is activated to return to the articulated position.

Reference numeral 21 denotes a pressing plate that slides on the guide rail 17, and the pressing plate 21 moves between the normal position shown in FIG. It is reciprocated by an air cylinder 22 attached to the stand 8.

23 is a stopper attached to the bottom surface of the base 8;
3 restrains the pack member 5 fed onto the support rail 18 in position.

Reference numeral 24 denotes a pressing plate that presses down the pack member 5 on the support rail 18, and the pressing plate 24 has a lower end of a piston rod of an air cylinder 25 that is fixed upright on the base 8 and a vertical shaft that slidably passes through the base. The guide shaft 26 is fixed, and the pressing plate 24 descends while pushing open the support rail member 18 until the pack member 5 is placed on the pack 4 on the transport frame 27.

The transport frame 27 has fitting holes 28 for the pack 4 on both sides,
A constant pitch T on the guide rail inside the conveyor frame 1
Endless conveyor chain 2 that runs in the direction of the arrow at intervals
The conveyor frames 27 are attached at each pitch for 9.29 seconds, and each conveyance frame 27 is stopped with the fitting hole 28 located directly below the press plate 24 one after another.

Reference numeral 30 denotes a rail-shaped receiving plate attached to the conveyor frame 7 so as to always cover the lower side of the fitting hole 28 of the conveyor frame 27. They face each other with a small gap between them.

The air cylinders 13, 15, 22, and 25 are sequentially controlled from their normal positions shown in FIG. 2 to perform the following operations.

First, the air cylinder 13 is extended, and the arm 11° horizontal axis 9
The lower end of the stacking pack member 5 on the opposing catch claw 1 is held under pressure by the opposing clamp arm 2 as shown in FIG. After sucking the lower end pack member, the nozzle 3 descends and places the pack member 5 on the guide rails 17 on both sides as shown in FIG. Then, by expanding and contracting the air cylinder 22, the pack member 5 on the guide rail is moved through the pressure plate 21 to the both side support rails 18 as shown in FIG.
After being transferred upward, the pack member is supplied via the press plate 24 by the expansion and contraction of the air cylinder 25 onto the pack 4 in the conveyance frame 27 that is stopped directly below it, as shown in FIG.

For this reason, packs 4 are filled with contents and transported sequentially.
When it stops directly under the pressing plate 24, it is automatically covered.

In the present invention, when the lower end pack member supported on the both side catch claws 1 is pulled out downward by the vacuum suction nozzle 3, the lower end of the both side clamp arms 2 rotated to the closed position in a vertical plane is pressed. Since the lower layer of the stacked pack members on the receiving claws is compressed and deformed by the surfaces 2a and 2a, the upper adjacent pack member is inclined with respect to the lower end pack member on the both receiving claws 1. Since the receiving flanges of one of the pack members are in close contact with each other in the upper and lower sides, even if the adjacent pack member is attached to the lower end pack member, the adjacent pack member will not touch the opposing pressing surface 2a of the lower end. The auxiliary catch pawl 1a protrudes from the surface 2a, and is retained between the catch pawl 1 and the auxiliary catch pawl 1a.

This remaining pack member remains on the auxiliary catch claw even after the clamp arm 2 is opened, and is taken out downward by the next removal operation of the clamp arm and the vacuum suction nozzle.

Therefore, according to the present invention, even if the pack members filled in the stacking frame are not stacked correctly and horizontally, it is possible to completely prevent the pack members from coming out and to ensure that they can be taken out individually. be.
