Description

[Detailed description of the invention] [Industrial application field] This invention is a gluing device for plate-like objects, more specifically, a device that automatically applies glue to the four peripheral surfaces of a rectangular plate like a sliding door frame. This relates to a gluing device for gluing.

[Conventional technology]

For example, to attach fusuma paper to a fusuma frame, apply glue to the four circumferential edges of the fusuma frame, fold the four circumferential edges of the fusuma paper stacked on the fusuma frame along the fusuma frame, and remove the folded parts. This is done by adhering with glue.

By the way, since gluing on the peripheral surface of the sliding door frame has conventionally been done manually using a brush, there are problems in that special techniques are required and work efficiency is poor.

This idea was made in order to solve the above-mentioned problems, and it is a board that can automatically apply glue to the four edges of a plate-shaped object, improving efficiency and saving labor in gluing work. The object of the present invention is to provide a gluing device for shaped articles.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention includes a conveyance mechanism that supports and transfers a rectangular plate-like object in an upright manner, and a peripheral surface of the plate-like object supported by the conveyance mechanism comes into contact with each other. an elevating gluing roller disposed so as to be movable up and down in a position and for applying glue to three circumferential surfaces of the plate-shaped object, that is, a front edge surface and an upper edge surface in the moving direction, and a rear edge surface in the moving direction; It is arranged to move up and down together with the gluing roller, and when it is raised, it detects the upper edge of the plate-like object, and stops the elevating and lowering gluing roller at a position where it comes into contact with the upper edge of the plate-like object. an upper edge detector that activates a mechanism in the feeding direction of the plate-shaped object; and a fixed position that is arranged to contact the lower edge surface of the plate-shaped object fed by the conveyance mechanism and that applies glue to the lower edge surface. The transport mechanism detects the front edge surface of the plate-like object in the moving direction while the transport mechanism is transporting the plate-like object, and moves the transport mechanism so that the front edge surface of the plate-like object contacts the lifting and lowering gluing roller. At the same time, a front edge surface detector moves the lifting gluing roller upwardly, which is waiting at the lowered position, and detects the trailing edge surface in the moving direction of the plate-like object, and detects when the trailing edge surface of the plate-like object reaches the lifting gluing roller. The configuration includes a trailing edge detector that stops the conveyance mechanism so as to contact the roller and moves the elevating gluing roller downward from the raised position.

[Effect]

When a plate-like object is placed and fed to the receiving side of the conveyance mechanism and the start switch is pressed, the conveyance mechanism is activated and the plate-like object is sent forward. Upon detection, the conveyance mechanism stops, and at the same time, the elevating gluing roller that is waiting at the lowered position moves upward, and the gluing roller contacts and rolls against the front edge surface of the plate-shaped object to apply gluing, and the upper edge When the detector detects the upper edge of the plate-shaped object, the elevating gluing roller stops at the raised position, and at the same time, the conveyance mechanism is activated to send the plate-like object forward again, and the elevating gluing roller When the upper edge surface of the object passes in contact with the upper edge surface and the detector detects the trailing edge surface of the plate-shaped object, the conveyance mechanism stops and the lifting and lowering gluing roller moves downward to glue the upper edge surface of the plate-like object. The elevating gluing roller contacts and rolls against the trailing edge of the plate-like object to apply glue, and when the elevating gluing roller returns to the lowered position, the conveyance mechanism is activated and sends the plate-like object to the end on the removal side. At the same time, while the plate-like object is moved from the receiving side to the take-out side by the conveyance mechanism, the lower edge surface contacts and passes over the fixed position gluing roller, and the plate-like object sent to the take-out side has its four circumferential surfaces. Glue will be applied.
