2. Description of the Related Art In a food processing manufacturing plant for canned foods, frozen foods, prepared foods, etc., punched empty cans made of aluminum and synthetic resin weighing plates and containers for weighing and filling meat are stacked in tens. Since it is transferred and carried in, the contents must be packed in the empty cans and empty containers, and one can or one plate must be separated in the process before weighing. Conventionally, this separation work that has been done manually has been mechanized, but in most cases, the bottom of the stacked empty container is held down with a claw-shaped object, and this lowest empty container is held by an air cylinder or solenoid. It is a system that operates and adsorbs, and separates and drops each piece.

[0003]

When this separation is carried out manually, in addition to the problem that the labor cost rises due to lack of manpower, especially in the case of aluminum punched empty cans, there is a problem between the containers. Since it is in a pressure state, it cannot be easily separated by manual work, and there is a problem that the separation work is hindered. In the case of automatic mechanization, if the laminated empty container is a punched aluminum can and is a deep-drawing can, in particular, a negative pressure condition is maintained between the containers as described above. Therefore, there is a problem that the container cannot be easily separated even by a mechanical suction means and the container is damaged. Also, it is structurally complicated and difficult to maintain,
There were many problems such as two or more overlapping containers depending on the accuracy and hardness of the containers.

The present invention is intended to solve the above problems, and an object thereof is to reliably separate and drop containers one by one without damaging them.

[0005]

SUMMARY OF THE INVENTION A first invention to obtain a patent is a hopper table on which a driving source is mounted and a drop hole is formed in the center of a base, and a peripheral portion of the drop hole of the hopper table. A plurality of hopper rods that stand vertically in the vertical direction and that support empty containers in a stacked state, and a plurality of rollers that have a spiral portion axially installed on the vertical upper surface around the drop holes of the hopper table. And a plurality of rollers are simultaneously rotated to separate empty containers one by one.

[0006] The peripheral flange portion of the empty container at the lowermost end, which is thrown into the hopper rod in a stacked state in a stacked state, is bitten into the spiral groove of the rotating roller to forcibly guide and guide the container downward to guide the container. Each piece can be reliably separated and dropped, and can be sent to the next process for packing the contents.

A second invention, which is going to receive a patent, is provided with a sensor section in the first invention, and when the absence of an empty container is detected in the hopper rod, the roller is interlocked to stop the roller. It is designed to prevent the idling of.

[0008]

The present invention is mainly used in food processing factories for canned foods, frozen foods, prepared foods, etc., and the process and the step of packing the contents into an aluminum punched empty can or a synthetic resin weighing container and a meat filling empty container. In the process, empty cans, empty containers, and weighing pans are mechanically sent to the next process one by one, and a plurality of rollers having a spiral portion are rotated by a drive source such as a motor. Then, by inserting dozens of stacked empty containers into the hopper rod, the peripheral flange of the empty container at the bottom end bites into the spiral part of the rotating roller and is forced by the spiral projection. The empty container at the bottom is separated from the other empty containers in the stacked state and surely drops one by one from the drop hole of the hopper table onto the conveyor belt below and is sent to the next process. Be done.
