Description

Description: TECHNICAL FIELD The present invention relates to a curing device for a joint panel formed by adhering a plate material to a frame material.

(Prior Art) In general, a panel is manufactured by applying an adhesive to a frame material formed of aluminum and adhering a plate material formed of synthetic resin to the frame material. In this case, the adhesive is cured for a certain period of time so that the adhesive is sufficiently dried and cured to firmly bond the two. Specifically, the joined panels are stacked vertically and pressed by a press for a certain period of time to dry and cure.

(Problems to be solved by the invention) However, the curing work by such a conventional technique is
Since it is carried out in batch processing, a time lag inevitably occurs between the bonding panel located in the lower layer and the bonding panel located in the upper layer in drying and curing the adhesive, and as a result, when using an adhesive with a fast reaction rate. However, there was a limit to the number of bonded panels that could be stacked, and there was a limit to improving productivity.
In addition, the lower bonded panel and the upper bonded panel have different loads, and it is difficult to apply a uniform pressing force to each bonded panel, which causes a problem in that quality varies.

The present invention has been made in view of such a problem, and provides a curing apparatus for a joint panel capable of continuously curing the joint panel under a uniform pressure.

(Means for Solving the Problem) The present invention relates to a carry-in conveyor that conveys a cavity on which a joining panel is placed to a set position, a chain that fixes a large number of dogs that support the cavity, and the chain that is wound. A lifting device consisting of a sprocket, a chain provided adjacent to this lifting device, which is fixed to a number of dogs that support cavities, and a descending device consisting of a sprocket around which this chain is wound. The transfer device for transferring the cavity raised to the lower position to the lowering device, the carry-out conveyor for transporting the cavity lowered by the lowering device to the set position, and the transfer device provided above the carry-in conveyor and the carry-out conveyor and raised from the lowering device. Consists of a conveyor that conveys weights to the equipment side,
The cavity is formed with a notch so as not to interfere with the weight transfer conveyor, and the weight is received from the transfer conveyor and placed on the bonding panel in the process of raising the cavity in which the bonding panel is mounted by the lifting device. On the other hand, on the other hand, in the process of lowering the cavity by the lowering device, the weight is configured to be supported by the conveyor and to be separated from the joining panel.

(Function) An adhesive is applied to the frame material, a plate material is adhered to form a joint panel, the joint panel is placed on the cavity and conveyed to a set position by a carry-in conveyor. When the joining panel is brought into position, the lifting device is activated and the dog fixed to the chain supports the cavity and lifts it upwards. On the other hand, above the carry-in conveyor, the weight carried in by the carry conveyor is supported and stands by.

By the way, a notch is formed in the cavity that is raised by the lifting device, and the notch prevents the cavity from interfering with the weight conveyor. Therefore, the cavity receives the weight in the process of rising by the lifting device and separates the weight from the conveyor. As a result, the weight presses the joining panel placed on the cavity, and the joining panel rises in a state where a constant pressure by the weight acts.

When the joining panel reaches the set height position by the lifting device, the transfer device is operated to grip the cavity on which the joining panel pressed by the weight is mounted, receive it from the lifting device and transfer it to the adjacent lowering device. The cavity transferred to the lowering device is supported by a dog fixed to the chain of the lowering device with the joining panel and the weight placed on the upper surface thereof, and moves downward.

Then, when the cavity reaches the position where the weight conveyor is installed, the notch portion of the cavity avoids the conveyor and continues to descend, so that the weight is supported by the conveyor in the process of descending by the lowering device, Is separated from the joining panel. When the cavity on which the joining panel is mounted further descends and reaches the set height position by the descending device, it is detached from the descending device and placed on the carry-out conveyor, and is conveyed to the set position by the carry-out conveyor.

In this way, the time until it is carried in by the carry-in conveyor and carried out by the carry-out conveyor is the dry curing time,
The bonded panel can be continuously cured under a constant pressure.
