Description of the Related Art For containers, films, toys, etc., a resin molding machine such as an injection molding machine or an extrusion molding machine is used, and the resin raw material supplied from a hopper is used as a screw and a heat inside the resin molding machine.
Melted and kneaded with a mixer, extruded into a film from a die,
Alternatively, it is manufactured by directly extruding or injecting it into a mold.
Since there is a limit to the capacity of such a hopper, it is usually the case that the operator waits for the time when the resin pellets or powder in the hopper become empty, and the operator has a predetermined weight (for example, 20 kg) of the resin raw material. The paper bag filled with was broken and the resin raw material was supplied into the hopper about 1 to 6 times per hour.

ることが行われている。However, when the number of resin molding machines in a molding factory has increased and the resin molding machines themselves have become more automated, the supply of resin raw materials to a large number of resin molding machines has relied on the labor of workers. In this case, the labor of the operator becomes great, and the raw material supply may not be in time. Also, the work of disposing of empty paper bags is difficult. Therefore, the automatic supply of the resin raw material to the resin molding machine is achieved, and in a molding plant with five or more resin molding machines, a pipe that can empty the resin raw material is installed in the ceiling part of the molding plant. Hopper
When a signal indicating that the resin raw material inside is empty is received, the resin raw material is fed by this pipe to supply the resin raw material to the popper.

う問題点があった。However, in the method of automatically supplying the resin raw material using the pneumatic piping, since the piping is installed in the ceiling part of the molding factory, the noise of the pneumatic transportation is extremely great when the resin raw material is supplied, and When exchanging resin raw material to another resin molding machine, which raises the nerves of the operator, it is necessary to circulate only compressed air in the pipe for cleaning, and at this time too much noise is generated. There is a problem in that a small amount of the resin raw material used in the above may remain, and this may be mixed with the resin raw material in the next molding to produce a nonstandard product.

ともに作業時間も短縮化される。Further, the container supply station is in the low position.
Since the container filled with the resin raw material in advance is stored on the conveyor, it is not necessary to frequently fill the container with the resin raw material, which reduces the labor and the working time. .

樹脂原料の自動供給方法。1. A container and a hopper are connected to indicate that the resin raw material in a container placed on a container placing table of a raw material supply station for supplying a resin raw material to a hopper of a resin molding machine is consumed. It is detected by a raw material detection sensor installed in the middle of the pipeline, and a feed container request signal is sent from the raw material supply station control device to the automatic guided vehicle control device to send a container transportation command to the initial position from the automatic guided vehicle control device. At least two containers that are in standby can be held and sent to an automated guided vehicle having an arm that can move up and down, turn, and move back and forth to drive the automated guided vehicle to a predetermined container supply station, and Roller on which a container can be placed
The container filled with resin raw material from the conveyor is held on one side of the arm of the automatic guided vehicle, and the automatic guided vehicle is run to the raw material supply station that has transmitted the detection signal, and the container mounting table of the raw material supply station. The empty container is held on the other side of the arm of the automated guided vehicle, and the container filled with the resin raw material held on one side of the arm is placed on the container mounting table to move the automated guided vehicle. Travel to the specified container supply station again, place an empty container held on the other side of the arm on the roller conveyor, run the automatic guided vehicle to the initial position, and transport the next container. An automatic supply method of resin raw material to a resin molding machine, characterized by repeating the operation of waiting there until a command is received.
