DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a transfer cargo holding device used in a pallet loading device or the like.

[Technical background of the invention]

In recent years, simple pallet loading devices have been developed that move cargo holding devices that clamp and hold one item in the vertical direction and both directions;
It has been considered that a predetermined number of items to be loaded on a pallet in one stage can be transferred in a plurality of times by using a device that moves in both directions and in the front and rear directions.

[Problems with background technology]

However, when an item is held by clamping, the clamping compresses the item, albeit slightly, and deforms the clamping body. As a result, the items may move in the direction in which they were clamped, making it impossible to load the items accurately, which poses problems in terms of packaging and safety.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned points, and is intended to prevent movement of the article when the article is separated in a transfer cargo holding device that clamps and holds the article.

[Summary of the invention]

The transfer cargo holding device for the fangs 1 of the present invention includes a support frame attached to a moving body, a clamping body for the fangs 1 provided at the lower part of one side of the support frame for holding the product, and a support frame other than the support frame. a clamping body for the spear 2 on the other side of the item, which is rotatably supported on the lower side and moves forward and backward with respect to the first clamping body by rotation to clamp the item between the clamping bodies of the spear 1; a guide body that is rotatably supported on the lower part of the other side of the support frame and moves forward and backward with respect to the first clamping body by 70 rotations to face the other side of the item between the respective clamping bodies; , when releasing the article held between the respective clamping bodies, the second clamping body is rotated to retreat, and the article is slid down along the guide body, whereby the article is moved. This is one way to prevent this from happening.

And, the second aspect of the present invention is the transfer cargo holding device mentioned above.
In this device, the clamping body and the guide body of the spear 2 are pivotally supported at the bottom of a movable frame, and the movable frame is movably provided on the other side of the support frame, so that it can move forward and backward with respect to one side of the support frame.
