Abstract

PURPOSE:To reduce manpower by loading and unloading a container automatically by a simple device without requiring mans' work. CONSTITUTION:In a handling device to load and unload containers stacked high in stages in close contact with each other on a pallet, when a cylinder 13 of a robot hand body 10 approaching the container on the pallet is driven, a metal fitting 14, a lever 16, a pin 17, a pin 18 and a guide roller 19 are operated along a rod 15. A claw 20 operates in a half ellipse with a pin 22 as its fulcrum, and is hooked on one grip part of the close contact container, and separates the container while raising it. Next, when a cylinder 23 of the hand body 10 is driven, a metal fitting 24, a lever 26, a pin 27 and a pin 28 are operated along a rod 25, and a claw 30 on the tip of the rod 25 rotates by 90 deg. with a pin 29 as its fulcrum, and are hooked on the other grip part of the container 1, and it is raised.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading and unloading palletizing robot handling device for containers on pallets.

[0002]

2. Description of the Related Art When moving a large number of containers, the containers are piled up on a pallet. The container has a structure in which the stacked parts do not move because the stacked parts move and fall due to the vibration during movement. Also, stacking the containers in close contact will stabilize them. For this reason, a person's fingertips are applied to the handle portions of the containers that are in close contact with each other and stacked, and the container is lifted and moved, and the fingers on both handle portions are lifted and lifted to load and unload.

[0003]

However, the above-mentioned conventional methods have a drawback that work efficiency is poor due to manual work and back pain and injury due to work fatigue occur. Therefore, the present invention is provided in the robot, without requiring human labor,
It is intended to provide a handling device capable of loading and unloading.

[0004]

According to the present invention, as a handling device for loading and unloading containers that are in close contact with each other on a pallet and stacked high, a claw portion that is hooked on a handle portion on one side of the container is provided. Then, a hooking / separating mechanism is provided which hooks this claw portion on one side of the handle portion of the uppermost container and laterally separates it while lifting the uppermost container. It has a claw that can be hooked on the handle on the opposite side of the container, and after the uppermost container is lifted and pulled apart by the lifting and separating mechanism, this claw is hooked on the handle on the opposite side of the uppermost container. Provide a lifting mechanism that lifts.

[0005]

In the container loading and unloading handling device of the present invention constructed as described above, the claws of the lifting / pulling mechanism make the topmost contact, and the claws are hooked on the handle part on one side of the stacked containers. Then, the container is separated while lifting, and the claw portion of the lifting mechanism lifts and moves the opposite side of the container to the handle part on the opposite side of the container where there is a gap in the close contact part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of the present invention, which comprises a hand body 10, a claw 11 and a claw 12.

As the unloading operation of the palletizing robot, the hand body 10 attached to the palletizing robot moves to the upper part of the pick-up position of the containers 1 that are in close contact and stacked.

Next, when the cylinder 13 attached to the claw portion 11 of the lifting and separating mechanism is driven, the metal fitting 14 moves downward along the rod 15 and approaches the container 1.

A lever 16, a pin 17, and a pin 18 are connected to the metal fitting 14, and a guide roller 19 and a claw 20 are connected.

A guide bracket 21 is provided on the hand body 10.
Is attached, and the guide roller 19 moves along the dog-legged guide groove of the guide bracket 21.

The pawl 20 moves in a semi-elliptical shape in accordance with the movement of the guide roller 19 with the pin 22 in the elliptical groove as a fulcrum.

When the metal fitting 14 is further moved downward, the guide roller 19 is moved downward from the upper end of the guide groove, and the tips of the claws 20 are hooked on the handle portions on one side of the container 1 which are in close contact with each other. While pulling up, pull apart in the horizontal direction.

Next, when the cylinder 23 attached to the claw portion 12 of the lifting mechanism is driven, the metal fitting 24 causes the rod 25 to move.
Works downwards along.

A claw 30 is attached to the tip of the rod 25 and rotates 90 ° about the pin 29 as a fulcrum.

A lever 26, a pin 27, a pin 28, and a pin 29 are connected to the metal fitting 24. When the metal fitting 24 moves downward, the claw 30 supported by the spring 31 of the lot 25 approaches the container 1.

When the metal fitting 24 is further moved downward, the lever 26 is lowered and the pin 29 is rotated by 90 °, and the tip of the claw 30 is hooked on the handle portions on the opposite side of the container 1 which are in close contact with each other to lift the container 1. .

The palletizing robot moves to the loading position with the hand body 10 lifting the container 1.

For loading, a series of operations opposite to unloading is performed, and the number of stacked containers 1 is repeated to finish.

[0019]

According to the present invention, robot palletizing work for containers eliminates work fatigue and back pain, and saves labor.
