Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a device for applying adhesive for laminating toe covers for slippers.

[Conventional technology and its problems]

Toe cover A for slippers is made by sewing the instep side edges of the cut outer material 1 and lining material 2 as shown in FIGS. The lining material 2 is turned over, and the outer material 1 and the lining material 2 are bonded together via an adhesive a applied to both or one of the back surfaces.

The application of the adhesive is done manually using a brush, which causes hand fatigue and significantly reduces efficiency.
There was a problem that caused the cost to rise.

Furthermore, since the adhesive is applied using a brush, the thickness of the applied adhesive is not uniform, and there is a problem in that the adhesive may not be applied uniformly, causing defective products.

Therefore, the present invention provides an adhesive application device for toe coverings for slippers, which applies adhesive via a roll to only the back surface of the outer material of the supplied toe covering material or to both the back surfaces of the outer material and the lining material. With the goal.

[Means to solve the problem]

In order to achieve the above purpose, this device has a hopper that stores a large number of toe covers lined up so that they can be taken out from the front row, and a hopper that takes out the toe covers from the front row and drops the taken out toe covers. A take-out device is installed to feed the toe cover, a pair of applicator rolls are placed on both sides of the toe cover falling path and drive the toe cover in the downward direction, and the lower circumferential surface is applied to the adhesive in the tank. It is constructed of a transfer roll that is recessed and has a drive function so that its upper circumferential surface can be adjusted to a non-contact state or a contact state with the circumferential surface of the application roll.

[Effect]

A large number of toe covers stored in the hopper are intermittently taken out from the front row by a take-out device that moves back and forth.

The taken out toe covering falls between the pair of applicator rolls and is grabbed by both the applicator rolls and falls down.

Since the liquid adhesive in the tank is transferred to the application roll via the transfer roll, the adhesive from the application roll is applied to the toe cover.

If the transfer rolls of both tanks are brought into contact with the application rolls, the adhesive will be applied to both the outer material and the lining of the toe cover, and the adhesive will be applied to either the outer material or the lining. In this case, the transfer roll may be brought into contact only with the application roll located on the application side.
