Description

PALLET FOR HAVING LATCH DEVICE}

The present invention relates to a pallet employing a latching device, and more particularly, to a pallet employing an improved latching device in order to improve safety when moving after loading a load and to increase the loading quantity of the load.

Conventionally, as a pallet for loading a plate-like object such as an automobile roof, a plate-like material is loaded by directly fixing four vertical posts to four corners of a flat main frame in which a square frame is formed in a rectangular shape. Each load was loaded one by one, followed by several long rods of metal or plastic on it, and then the load was loaded again.

As a result, it is difficult to load the load stably and to load a long rod one by one, which requires a lot of loading time, a lot of manpower consumption, and a constant and even loading. In addition, there are many defects, such as the stability of the load is difficult to slide down and thus there is a risk of safety accidents.

In order to solve the above problems, as shown in FIGS. 1 to 3, the pallet A fixes the auxiliary reinforcement frame 3 at a predetermined position slightly inside the main frame 1 and the main post 2. Then, the latch post 4 is installed on the auxiliary reinforcing frame 3, and the latch 7 is arranged up and down at a predetermined interval over the entire surface of the latch post 4 side.

At this time, the shape of the latch 7 is the inner end (5) of the inner side is narrow and the middle jaw (10) is formed or not, the outer end (6) is composed of a wide plate-like golf body shape is configured to be curved in the center The central portion of the latch 7 is extrapolated to be rotated on the outer circumferential surface of the tube rod 11, and the tube rod 11 is connected to the latch post by a bolt 8 and a nut 12 together with two-sided washers 9. Fix it to (4) at regular interval

The upper curved surface 13 of the latch 7 is positioned to slightly push the upper curved surface 13 ′ of the latch 7 located directly above when the latch 7 is folded into the pallet A. In the center position between the latches (7), the stopper (16) to which the nut (15) is fastened with the lock bolt (14) is positioned, and the lowermost latch (7) is located at the lower outer corner of the lower latch post (4) below. The lower right stopper 17 of the fixed right-angle triangular shape is mounted so as to be slightly inwardly of the pallet A.

In this way, when loading the plate-like load using the pallet A on which the plurality of latches 7 are mounted, the plate-shaped load transferred to the robot arm (not shown) is previously latched slightly inward by the lowermost stopper 17. When placed on (7), the latch (7) is completely folded, and a part of the upper curved surface (13) of the latch (7) touches the stopper (16) while the upper surface near the end of the latch (7) is directly above it. The lower curved surface 13 'of the latch is pushed slightly so that the upper latch is slightly flipped to the inside of the pallet A so that the next load can be loaded immediately.

Therefore, when the load is continuously loaded, the latches 7 are easily flipped so that the loads are easily placed in turn, and thus, the loads are continuously useful to accurately and uniformly and safely load the load continuously.

Such a pallet (A) is disclosed in Korean Utility Model Publication No. 1994-0003338.

However, in the conventional pallet as described above, for example, a panel for a vehicle is loaded using a robot, but since the panel is stacked one by one for each latch 7, the pallet is transferred and transported in a vehicle. Panels loaded in the door can be dismounted, especially if they are light.

When one panel is loaded on a pallet, the next latch 7 rotates on the curved surface of the latch 7 due to the weight of the panel, so that only one panel is loaded per latch 7, thereby reducing the number of panels. . As a result of the overall production line of the vehicle, since the pallet replacement time is increased, the production time is much longer.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a pallet employing a latching device for improving safety when moving after loading of a load and increasing the loading quantity of the load.
