Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a loaded object removal device for taking out stacked plastic boxes and the like one by one.

[Conventional technology]

Conventionally, plastic boxes and the like for temporarily storing workpieces such as pressed products have been placed empty and side by side on a flow rack until they are used. Therefore, the space within the factory was wasted, which was one of the causes of a reduction in free space within the factory. In order to solve this problem, plastic boxes and the like can be stacked vertically, but it has been difficult to take out the stacked plastic boxes and the like one by one when using them.

To take out plastic boxes one by one from a stack of plastic boxes stacked one above the other, for example,
Application of the device in Publication No. 11141 can be considered, but unless it is mechanically connected to the roller conveyor that transports the plastic boxes to the desired position after being removed from the load, the effectiveness of automation will be halved. It ends up.

[Problem that the invention attempts to solve]

The purpose of this invention is to be able to easily take out loaded items such as stacked plastic boxes one by one, and also to be able to be linked with a transport device to transport the loaded items that have been taken out to a desired position. The object of the present invention is to provide a device for taking out a loaded object.

[Means for solving problems]

To achieve the above object, the load retrieval device of the present invention has a group of locking pins on both sides of the load, which are vertically stacked plastic boxes having flanges on the upper and lower parts, which can move forward and backward into the load. Arranged in two stages, the locking pin groups in the upper and lower two stages are rotated around a rotation axis so that the upper locking pin group and the lower locking pin group alternately advance and retreat from the loaded object. They are connected via a pin mounting plate, and the rotating shafts on both sides of the load are slidably pivoted to each other so that the groups of locking pins on both sides of the load move forward and backward in the same way relative to the load on both sides. Connected via a driving link and a driven link,
The roller conveyor, which is rotatably supported around a fulcrum, is arranged so that when the lower locking pin group moves in the direction of retreating from the loaded object, the portion of the roller conveyor located below the loaded object springs diagonally upward. A loaded object takeout device connected to a drive link such that when the lower locking pin group moves in a direction approaching the loaded object, a portion of the roller conveyor located below the loaded object tilts diagonally downward from a fulcrum of the roller conveyor. Consists of.

[Effect]

In the above device, the plastic boxes are dropped one by one from the loaded object by the alternating forward and backward movement of the upper and lower groups of locking pins. The roller conveyor is mechanically linked to the movement of a group of locking pins and rotates upward and downward around a fulcrum, and when a plastic box falls, it springs upward and lifts the plastic box onto the roller conveyor. The roller conveyor is guided by its own weight to the loading position for the plastic box at one end according to the inclination, and when the locking pin group moves to lock the plastic box, the roller conveyor is moved diagonally downward around the fulcrum. The plastic box placed at one end of the roller conveyor is guided by its own weight to the take-out position at the other end of the roller conveyor. In this way, the plastic boxes are taken out from the load one by one purely mechanically, and the workpieces are put into the plastic box at the one end of the roller conveyor, guided purely mechanically to the take-out port, and taken out. Since the movement of the roller conveyor is mechanically linked to the movement of the locking pin group, operation is reliable.

2 and 12 are fixed respectively, and a pair of upper and lower locking pins 13, 13, 14, 14, 15, 1 are respectively fixed to these pin mounting plates 11, 11, 12, 12.
5, 16, 16 are rotatably attached.
Locking pin 13, 13, 14, 14, 15, 15,
16, 16 are movable into and out of the guide member 2, and among these locking pins, the locking pin 1
3 and 15 and locking pins 14 and 16 are arranged at corresponding heights and positions, respectively. In addition, in the figure, 1
7, 17, ... are locking pins 13, 14, 15, 16
This is a guide.

On the other hand, below the guide member 2 is a roller conveyor 1.
8 are disposed, and the roller conveyor 18 is rotatably supported on the base 3 via a shaft 19 (fulcrum of rotation). One end of the roller conveyor 18 engages with the drive link 9, and a tension coil spring 20 is interposed between the roller conveyor 18 and the drive link 9. A weight is attached to the other end of the roller conveyor 18, and biases the link so that it always maintains its original position. Further, the other end of the roller conveyor 18 is located at a product loading position A, where products are loaded into a load such as a plastic box. 21 is the drive link 9
The wire 21 has one end connected to the roller conveyor 18 and a handle 22 attached to the other end. and,
23 is a pulley, and 24 is a roller conveyor fixed on the base 3.

Next, the operation of the above device will be explained.

First, the loaded objects 1, 1 are stacked upwardly and accommodated in the guide member 2 as shown in FIG. 5A, and the outer peripheries of the loaded objects 1, 1, .
is formed. When plastic boxes 25 and 26 as shown in FIGS. 8A and 8B are used as the load 1, flanges 25a and 26a must be formed on the outer periphery of the boxes 25 and 26, respectively.

As shown in FIG. 1, FIG. 5A, and FIG. , 15 protrude, respectively, so that the lowermost load 1 has its flange portions 1a,
1a is engaged with locking pins 13, 13, 15, 15 and locked.

Next, when the wire 21 is pulled, the drive link 9 rotates in the B direction about the rotating shaft 7 as shown in FIG. 5B, and the driven link 10 rotates in the C direction in conjunction with this. Then, as shown in FIG. 7, the upper locking pins 13, 13, 15, 15 retreat, and the lower locking pins 14, 14, 16, 16
protrudes, the load 1 falls and the lower locking pin 1
