Description

DETAILED DESCRIPTION OF THE INVENTION “Industrial application field” The present invention relates to a lid made of a synthetic resin for a package, and a heating device, a molding device, a punching device, a Thomson blade cutting, a separating device, and The present invention relates to a device for automatically continuously molding via a holding device, a vacuum pump, etc., and relates to a cutting / separating mold device using a Thomson blade in the device.

“Conventional Technology and Its Problems” Conventionally, a lid material that is fed through a feeding device from a supply roll wound with a sheet-shaped lid material made of synthetic resin is heated, molded, cut, and The package lid (hereinafter simply referred to as the lid) and the residual material piece are separated through a molding process such as a separation die and the like, and the lid material is taken out after being laminated and the residual material is also separated. The piece is separated from the residue material piece and the lid body by the embossing work by the Thomson blade in the automatic molding device of the lid body configured to be wound around the residue material piece winding roll. The piece and the lid are connected via a slight connecting portion. Therefore, after that, a suction work (suction process) is performed to separate the connecting portion between the residual material piece and the lid, and to cut and separate them. In other words, it is divided into two processes, the embossing process and the cutting / separating process. Then, after separating from the lid material, the lid is laminated through the moving operation and the reversal of the adsorption device, and then taken out. Therefore, it is necessary to provide a cutting / separating suction step consisting of a completely separate suction apparatus, or to install a storage shelf or the like, as the step of embossing the Thomson blade. Therefore, the structure becomes complicated, and the operation becomes complicated and the workability deteriorates. In addition, as described above, the connection part, which is the boundary between the lid and the residue material piece, cannot be completely cut / separated at the time of separation by suction work after embossing the shape with the Thomson blade, resulting in burr and bad appearance. However, there were problems such as poor quality and product value.

"Means for Solving the Problems" In view of the above, the present invention provides a complete cutting by the Thomson blade when the lid is cut and separated from the lid material, and at the same time as the cutting, the lid cut by the adsorption action is used. The work of sucking up and completely separating it from the sheet-shaped lid material is one step, and this one step can be done by one cutting / separating mold device, or the cutting and separating mold device using this Thomson blade For the purpose of simplification and downsizing, and also for cutting several lids at the same time or transporting them to a predetermined stacking position so that the several lids can be separated and taken out, etc. Adopt the configuration of.

That is, the device for cutting and separating the package lid in the automatic device for molding the package lid includes heating, molding, cutting die, separation die, etc. of the lid material fed from the supply roll through the feeding device. Through the molding process by the device,
Separated into a lid for packaging and a residue material piece, and taking out after laminating this lid, the residue material piece is an automatic molding device for a package lid configured to be wound around a residue material piece winding roll. The cutting and separating mold device using the Thomson blade includes a fixed lower mold device and an upper mold device that is movable up and down, in which a suction chamber is formed, a vacuum pump that communicates with the suction chamber, and the lifting and lowering mold device. The movable upper die device is configured to include horizontal movement of the upper die device and forward / backward movement means such as a cylinder provided in the vertically movable and movable upper die device. When the upper limit of the upper and lower parts can be moved up and down by the retracting means, the upper and lower parts of the upper and lower parts can be moved up and down in order to remove the lid for the package adsorbed by the upper and lower parts of the upper and lower parts which can be moved up and down. Wherein a structure to stop the adsorption function of the suction chamber provided in the.

[Operation] Next, the operation of the present invention will be described. The lid material fed from the supply roll through the feeding device is heated, molded, cut, and separated by a molding process by each device.
Separated into a package lid and a residue material piece, while taking out this lid body after stacking, this residue material piece is an automatic molding device for a package lid configured to be wound around a residue material piece winding roll, In particular, this structure has a feature in a cutting / separating mold device (hereinafter simply referred to as a cutting / separating mold device) using a Thomson blade.

That is, when this cutting / separation mold device is reached, there is a Thomson blade consisting of upper and lower molds, and specifically, an upper mold device that can move up and down moves down through contraction of the piston rod of the cylinder. Then, the Thomson blade of the fixed lower mold device screams,
Here, the lid body is completely cut from the lid body material to form a large number of lid bodies.

Simultaneously with this cutting, the suction chamber is placed under vacuum, and the large number of completely cut lids are sucked through suction from the suction nozzle. When this suction is completed, the upper mold unit that can be moved up and down and moved up through the extension of the piston rod, and returns to the initial state.

At the same time as the expansion and contraction of the piston rod, the upper and lower devices capable of moving up and down at the same time move forward in the horizontal direction by the extension of the piston rod of the cylinder. Release the vacuum state of. As a result, the lid that has been adsorbed by the upper die device that can be raised and lowered and moved is removed, and is stacked on the mounting table below this. On the other hand, the residue material piece from which the lid has been completely cut off is hung down slightly in front of the cutting / separating mold device and is wound around the residue material material winding roll via a tension adjusting device.

The above operation is continuously repeated, and after the lid body is stacked on the mounting table, the lid body is transported and stored at a predetermined place.

The invention of the present application is an automatic molding apparatus for a package lid, which is operated by the operations and procedures described above.
In cutting and separating mold equipment using Thomson blades,
The cutting work and the suction work are integrally performed in the same device and in one process. Furthermore, this cutting and immediately adsorbing work is performed, and a beautiful package lid without burrs is produced. However, in the conventional technique, the cutting operation and the suction operation are separate and independent steps, and the embossed residue material piece and the lid body remain connected through a small connecting portion (that is, the die In the pushing step, without completely cutting, leaving the connecting part which is the boundary between the lid body and the residual material piece), there is no choice but to send it to the next adsorption step.
At the time of separation by the suction work, the connection part, which is a boundary between the lid and the residual material piece, cannot be completely cut and separated, and remains as a burr, resulting in deterioration of quality.
