It further relates to a series of line systems for storing and loading the filled containers onto trucks.

(b) Prior Art Recently, flexible containers made of synthetic fiber bags have been widely used as a means of transporting powder and granular materials. Conventionally, in order to fill a container with powder or granular material and carry out cargo handling, the container was filled with powder or granular material using a hopper, and the filled container was then loaded onto a truck using a hoist or a forklift.

(c) Problems to be solved by the invention For this reason, a lot of manpower is required, and in order to load a predetermined number of containers all at once onto a truck, a hopper is used to transport each filled container one by one to the truck each time. This is because it takes a long time to load onto a truck, which is extremely inefficient for cargo handling.Also, in order to store filled containers according to the loading unit of the truck, it is necessary to transport the containers from the hopper to the stockyard using a forklift, etc. Furthermore, it was necessary to transport the material from the stockyard to the truck again, which required even more manpower and effort.

(d) Means for Solving the Problems The present invention aims to solve the above-mentioned problems by providing a series of systems comprising an empty hanger storage section, an empty container supply section, a filling section, a stock section, and a truck loading section. It consists of a power-and-free type trolley conveyor, and the filling section has two free rails separated by a predetermined distance, and the hanger is transferred to the two free rails by a turntable to convey the hanger laterally. A flexible container configured so that the power rail does not interfere with loading from the hopper, and the storage section has a predetermined length as a whole so that it can store a large number of hangers with full containers attached. in the filling and handling system.

(e) Effect Based on the above-mentioned means, the empty hangers waiting in the empty hanger storage area are sent one by one to the empty container supply unit, the empty containers are attached to the hangers in the empty container supply unit, and the hangers are further loaded. The empty container is sent to the filling section by the turntable and filled with granular material from the hopper, and the filled container is stored in a predetermined amount at the stocking section in response to loading onto the truck by the truck loading section. Immediately transport the full container hanger from the stocking section to the truck loading section.

In this state, when a truck enters the truck loading section 7, it immediately moves to the designated rail 1 corresponding to the truck.
The hangers 28 of 0e... are sent to the loading section 7. Then, by the loading section 7, the hanger 28 with the full container attached is transferred forward along the truck loading platform, further transferred to the side, and then moved downward at a predetermined position, so that the full container is loaded onto the truck loading platform. Ru. In this state, the full container is removed from the hanger, the container inlet 31a is tied, and the empty hanger is returned to the power chain 11 section and carried out to the empty hanger storage area 3, and at the same time the full container is attached to the next hanger. is loaded onto the truck bed at the loading section 7. In this way, full containers are loaded onto the truck one after another.

In the above embodiment, the rear trolley 13 is transported in the filling section 5 by the auxiliary dock 27 and the power chain 11a running at a low position, but this may be carried by other means such as an air cylinder.

(G) Effects of the Invention As explained above, according to the present invention, the empty hanger storage section 3, the empty container supply section 4, the filling section 5,
Since it consists of a series of power-and-free type trolley conveyors equipped with a stocking section 6 and a truck loading section 7, there is no need to transport the containers 31 one by one using a forklift, etc., resulting in significant labor savings. It is now possible to easily automate the entire process from feeding empty containers, filling powder and granules, to stocking and loading trucks, and in conjunction with a computer, the entire filling and cargo handling system, including rod management and truck loading unit management, can be automated. Management is also easier. In addition, the filling section 5 separates the free rails 10c and 10d for a predetermined period of time.
Since this is installed and configured so that the hanger 28 is conveyed in the horizontal direction, the power rail 9 does not get in the way when powder and granules are introduced from the hopper 35, and even though the trolley conveyor 2 is used, Powder and granular material can be fed from the hopper 35 without any support. Furthermore, when transferring the hanger 28 to the filling section 5, the hanger 28 is transferred laterally using the turntables 33a and 33b.
There is no need for branch switches, corner rails, etc. that require a large space, and the space efficiency of the entire system is improved, and the lateral transport space for filling by the hopper 35 can be utilized to the maximum. Furthermore, since the stocking section 6 has a predetermined length as a whole so that it can store a large number of hangers 28 loaded with full containers, the loading section 7 immediately removes full container hangers from the stocking section 6 in response to loading of the truck. truck loading time can be significantly shortened and cargo handling efficiency can be improved.
