Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a cargo handling method for a flexible container that is filled with powder or granules and transported.

(b) Conventional technology Traditionally, industrial chemicals, feed, etc. have been packed in paper bags and transported. However, in recent years, flexible containers have come to be used instead of paper bags, and are becoming the mainstream for transporting powder and granular materials.

As shown in FIG. 1, this flexible container a has two
Openings c and d are formed at locations, and binding means e and f are provided to close the openings c and d, and a hanging rope g is attached to the main body b.

Then, this flexible container a is
As shown in the figure, a rope g is hooked onto a fork h of a forklift, and the fork is suspended and moved.

As shown in Fig. 3, the flexible container a is placed on a flat conveyor i constituting a conveyance path, and the cargo is first transported from a hopper j through an upper opening c. After being introduced and filled, this opening c is closed by the binding means e. After the flexible container a is transferred on the flat conveyor i, the flexible container a is suspended by hooking a rope g to a fork h of a forklift, and is moved to a predetermined position.

(c) Problems to be solved by the invention However, in the above method, when hooking the rope g to the fork h, another worker is required in addition to the forklift driver to hook the rope g. , there was a problem that it required a lot of manpower.

In particular, flexible container a has a problem of poor handling during cargo handling, and it was considered to clamp the side of flexible container a in order to make the above-mentioned forklift work a one-man operation, but the deformation The disadvantage is that it is large and cannot be easily lifted.

To solve this problem of poor handling, it is conceivable to use a forklift equipped with a vacuum suction attachment (see, for example, Japanese Utility Model Application No. 56-62398). However, flexible body b
Suction force is applied to the upper part that is suctioned by the vacuum suction attachment, and this part bears the weight of the transported object, so the flexible body b
There was a risk of damage. Furthermore, the airtightness of the vacuum suction attachment to the upper part of the flexible body b is low, and there may be cases where the flexible container a cannot be suctioned and lifted.

In addition, the flexible container a is provided with two upper and lower openings c and d and binding means e and f,
This is because an upper opening c is required when loading the transported material from the hopper j, and a lower opening d is required when discharging the material into the silo.

However, this makes the structure complicated, the number of parts increases, and it becomes expensive.

This invention was made in view of the above,
The object of the present invention is to provide a flexible container cargo handling method that improves handling of the flexible container, enables labor saving and automation, and simplifies the structure of the flexible container.

(d) Means for Solving the Problems As a means for solving the above problems, the flexible container cargo handling method of the present invention includes a main body having one opening for filling and discharging transport materials such as powder and granules. A binding means for closing this opening is provided at the lower part, and the upper surface thereof is provided with high airtightness and strength against suction, and the flexible container filled with the goods to be transported is placed on the conveyance path with the opening located upward. In the middle of this transfer, the flexible container is carried between both clamp parts of a reversing device, which has clamp parts on the upper and lower sides and a stabilizer part on one side, and the rotating means of this reversing device is driven. After inverting the flexible container so that its opening is located downward, the flexible container is carried out from between the two clamp parts onto the conveyance path, and a vacuum suction cup of a forklift equipped with a vacuum suction attachment is pressed against the top surface of the flexible container. , the flexible container is moved while being held suspended, and the binding means is untied while the flexible container is held suspended to release the transported goods.

(e) Effect The flexible container cargo handling method of the present invention has the upper surface of the flexible container having high airtightness and strength capable of withstanding adsorption, so it is possible to vacuum adsorb the container and transport it. The cargo can be released by untying the binding means at the opening, and the problem of handling the flexible container can be solved.

On the other hand, since a flexible container only needs to have one opening and one binding means for closing the opening, the structure of the flexible container can be simplified and its cost can be reduced.
