As a result, both sliders 5 and 6 are maintained in a balanced state in terms of weight.

Reference numeral 45 denotes a cargo table installed on the base plate 2, the upper surface of which is connected to the side rods 31b and 31c of the comb rod 31.
and vertical slits 45a, 45'a having a width t and depth h sufficient to fit the support rods 31d, 31e.
and horizontal slits 45b, 45'b,
Further, a vibration transfer means 46 using an electromagnet is provided on the lower surface. The vibration transfer means 46 transfers the cargo 48 sent from the belt conveyor means 47 to the table 4.
A guide 49 is provided on the top surface of the table to perform an auxiliary function, and a phototube is used to detect the arrival of the cargo and start the vibration transfer means 46. 5
0 and a fixed position on the table, a phototube 51 is provided to detect this and stop the vibration transfer means 46.

The apparatus of the present invention is constructed as described above, and the operation of stacking the loads 48 on the pallet 52 will be explained. First, the lower slider 6 is moved by the motor 3
The comb rod 31 is lowered to the position of the loading table 45 by normal rotation drive of the comb rod 31 through the vertical and horizontal slits 45a, 45'a,
45b, 45'b. At this time, the upper slider 5 is at an appropriate position necessary for stacking the loads 48 on the support column 1, and this adjustment is performed by driving the motor 35 in forward or reverse rotation. In this state, the cargo 48 is sent from the belt conveyor means 47 onto the cargo storage table 45, the phototube 50 detects this, the vibration transfer means 46 is activated, and the cargo 48 reaches a fixed position on the table. Then, the phototube 51 detects this and the vibration transfer means 46 stops.

Next, in conjunction with this, the motor 36 is now driven in reverse, and the lower slider 6 is moved to the comb rod 3.
When the contact plate 32a comes into contact with the limit switch 28 of the upper slider 5, the motor 3
6 is stopped. At this time, the parent arm 8 of the upper slider 5 holds the child arm 14 inward, operates the slider 21 at a position above the comb rod 31 of the lower slider 6 that is rising, and releases the grip rods 20, 20'. When the motor 36 stops driving, the slider 21 is operated again to close the open gripping rods 20, 20' at a position above the comb rod 31, thereby removing the load. Both ends of the body 48 are held in and supported, while the gripping rod 2
In connection with the closing operation of 0 and 20', motor 3 is activated again.
6 rotates in the normal direction, the lower slider 6 moves downward, and the lower slider 6 stops when the contact plate 32b contacts the limit switch 33. At this time, the lower slider 5 is connected to its comb rod 31.
The vertical and horizontal slits 45a and 4 of the loading table 45
5'a, 45b, 45'b, and in conjunction with the operation of the limit switch 33, the load from the belt conveyor means 47 is fed again. That's right.

On the other hand, the gripping rods 20, 20' of the upper slider 5
The load 48 gripped by the motors 9 and 12 rotates the parent arm 8 and the child arm 14 as appropriate to move the load 48 to an appropriate position on the pallet 52. After confirming all the operations, the cylinder 21 is moved to the gripping rod 20,
20' is opened to allow the cargo 48 to fall. However, motors 9 and 1
2 is driven, the parent arm 8 and the child arm 14 are rotated, and the comb rod 31 of the lower slider 6 is rotated while the gripping rods 20 and 20' remain in the open state.
has returned to the position where it will lift the load 48 and is waiting.

In carrying out the loading operation, the order in which the objects 48 are placed on the pallet 52 can be determined arbitrarily, but once the arrangement in the first stage is completed, the order in which they are arranged in the second stage is different. In this embodiment, five loads 48 are arranged in each stage, and when all five loads are lined up, the motor 35 rotates in the normal direction to move the upper slider 5 to a predetermined upper position. It is then lifted up and prepared for the next load.

When loading is completed at the desired constant height position by repeating the above operations, the loaded pallet 5
2 is moved to another position by the fork list, and the newly placed pallet 52 is similarly loaded in its place.

In the device of the present invention, the upper slider 5 for loading cargo at a fixed height position and the lower slider 6 for lifting the cargo to a fixed height are provided in a slidable relationship with respect to one hollow support 1. , the structure is simplified and can be manufactured at low cost, and the gripping rod 2
0,20', the comb rod 31 of the lower slider 6 lifts the next object to be loaded to a certain height and waits for it, which results in time loss as a continuous operation. Loading operations can be carried out extremely efficiently with almost no occurrence of turbulence, and work performance can be dramatically improved.

In the above embodiment, the pillar 1 has a rectangular cross section, but it may also have a circular cross section. Further, the cargo is not limited to a wrapping bag, but may be a box. Although the vibration transfer means for the loading table uses an electromagnet in the explanation, it may also be carried out by converting the rotation of an eccentric cam into a linear reciprocating motion in the direction in which the load is sent. ,
Appropriate modifications and changes to other parts are free.
