Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a bottom-opening type cargo handling hanger.
It was developed for the purpose of streamlining the loading and unloading of fertilizer bags, rice and wheat bags, and other cargo onto ships, trucks, freight cars, etc.

<Conventional technology and its problems> Although it is convenient to carry out cargo handling work while a large number of cargoes are loaded on pallets or in containers, it is necessary to move the pallets and containers as well, resulting in a reduction in transport volume and recovery. However, it is time-consuming and uneconomical. Therefore, cargo handling work has conventionally been carried out by loading and unloading on pallets, but this has resulted in a heavy workload.

The present invention allows the cargo to be stacked directly on the hoist and moved without using pallets, and after being moved, the bottom of the hoist is opened and the cargo can be loaded and unloaded into a predetermined position in the same state as when it was moved. This is a specially designed bottom-open type lifting device for cargo handling. This basic idea had already been proposed by the present inventor as a bottom-opening container in Japanese Utility Model Application No. 151596/1983, but this was further developed into the bottom-opening cargo handling hanger of the present invention.

<Means for Solving the Problems> The gist of the configuration of the present invention is to divide two or more lifting belt groups 3, which are aligned almost parallel, into left and right sides, and to separate the left lifting belt 8 and the right lifting belt. A lifting belt 9 is formed with hook parts 6 and 7 at both ends of the left and right lifting belts, and is integrated with connecting belts 10 and 11, and a hook part 12 is provided at the tip at an intermediate position of the plurality of lifting belt groups 3. , 13 are attached to left and right lifting belts 8, 9, respectively, in a substantially perpendicular direction to the left and right.

<Example> Below, the bottom-open type cargo handling hanger of the present invention will be explained in detail with reference to the drawings.

FIGS. 1 to 4 are developed plan views of the bottom-opening cargo handling hanger.

Figure 1 can be said to be the basic model of the hanging device of the present invention, and the imaginary lines in the figure show the bottom and sides of the cargo unfolded in a cross shape with the bottom as the center.
The outline of the bottom surface 1 and side surfaces 2 is shown. In this case, the entire hanging device has an endless loop shape, and two lifting belt groups 3 and a left bottom opening belt 4 and a right bottom opening belt 5 as bottom opening belts are provided in a cross shape, and the lifting belt group Pull the two lines together and make a U on both the top and bottom ends.
Hook parts 6 and 7 consisting of letter-shaped ring differences are formed to divide the belt into a left lifting belt 8 and a right lifting belt 9, and connecting belts 10 and 11 are attached thereto. The lifting belt groups are connected to each other by connecting belts 10 and 11 at the hook portions.
Since they are integrated, it restricts the opening of the load lifting parts of the left lifting belt 8 and the right lifting belt 9, and prevents the lifting belt group from separating to the left and right.
The left lifting belt 8 has a left bottom opening belt 4.
The right bottom opening belts 5 are each independently fixed to the right lifting belt 9 in a cross shape. It is convenient to provide eye-shaped hooks 12 and 13 at the ends of the bottom-opening belt.

Figure 2 shows that the hooks of the lifting belt are provided with four independent eye-shaped hook parts 6a, 6b and 7a, 7b on the left lifting belt 8 and right lifting belt 9, respectively, and on the bottom opening belt. It differs from Fig. 1 in that the tips of 4 and 5 are made into hook parts 12 and 13 consisting of U-shaped ring differences, and the whole is made into a loop shape and is attached to the left and right lifting belts 8 and 9 at two places each. . By using four eye-shaped hooks on the lifting belt, the bag can be lifted with good balance between the left and right sides, so even wide items can be lifted stably without the bottom opening inadvertently.

FIG. 3 shows an example in which the group of lifting belts shown in FIG. 1 is changed to two sets of endless loop belts, making a total of four lifting belts, in order to more stably lift wider loads. The left and right bottom opening belts 4 and 5 are the first
It is similar to the one shown.

If the loop-shaped bottom-opening belt shown in Figure 2, which prevents the load from collapsing on the left and right sides, is added to the lifting belt group shown in Figure 3, the stability will be further improved than that shown in Figure 3, and it will be suitable for large loads. It becomes a lifting belt. In particular, this structure allows stable unloading of plastic bags and polypropylene flat yarn cloth bags, which are more slippery than paper bags and jute bags and tend to collapse.

Fig. 4 shows the hanger shown in Fig. 2 with two bottom-opening belts 4 and 5 (a, b) arranged in a cross pattern. Both of these differences are useful as the hanging tool of the present invention.

In addition, in FIGS. 1, 3, and 4, for the purpose of reinforcement, a central incision edge 18 is cut vertically in the center of the area surrounded by the left and right lifting belts 8, 9 and the upper and lower connecting belts 10, 11. , 19 formed on the reinforcing cloth 1
4 and 15 are sewn or welded, and temporary fixing pieces 16 and 17 made of fabric hook-and-loop fasteners, tying strings, etc. are preferably provided between the reinforcing fabrics on the sides of the luggage.

Although the embodiments of the hanging tool of the present invention have been described above, the present invention is not limited to these specific examples.

<Function> The method of using the hanger of the present invention together with its function will be explained as follows.

As shown in FIGS. 1 to 4, the hanger is spread out in a cross shape, and if necessary, a thick craft paper or synthetic resin sheet is spread on the bottom of the center part, and the items are stacked on top of it. Next, the bottom-opening belts 4 and 5 are applied to both sides of the baggage from the left and right, and temporarily fastened appropriately on the top surface. Finally, left lifting belt 8 of lifting belt group 3
a, 8b and the right lifting belts 9a, 9b from the front and back of the load to the upper surface, and connect the hook parts 6a, 7a and 6b, 7b of the upper lifting belt to the fork 24 of the forklift or the hook of the lifting crane. Lift it up and transport it. During cargo handling work, the left lifting belt 8 and right lifting belt 9 on the side of the cargo can be moved without opening to the left or right because the load is balanced, but for safety, the central cutout 18 of the reinforcing cloth 14, 15,
Cloth hook-and-loop fastener, binding piece, etc. between 19 and 1
6, 17 or the central incision edge 18 with a fastener
19 is temporarily fixed.

After lowering the cargo to a predetermined position, the hook parts 12 and 13 of the bottom-opening belts 4 and 5 are hoisted up using forks of a forklift, hooks of a crane, etc.
The right lifting belt 9 and the left lifting belt 8 on the bottom of the cargo move to the left and right to open the bottom, the cargo remains as it is without collapsing, and the hanging tool is removed without difficulty. Therefore, the trouble of manually reloading cargo can be saved.

In order to avoid the mistake of hanging the lifting belt and the bottom-opening belt when transporting cargo, it is possible to use different colors, such as making the bottom-opening belt red, or to change the thickness of the belt.

<Effects of the Invention> The bottom-opening cargo handling hoist as detailed above does not require manual movement of stacking rice bags, fertilizer bags, feed bags, and other cargo in a warehouse or unloading onto empty pallets. It can be made without any labor, can be used as a simple container as it is, and is easy to collect, making it a major contribution to labor-saving cargo handling.
