Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of a gluing device used, for example, in a label pasting machine, a paper interleaving machine, and the like.

(Prior Art) Conventionally, this type of gluing device is known, for example, as described in Japanese Utility Model Publication No. 8699/1983.

This basically consists of a glue roll, a glue transfer roll, a washing roll, a washing tank, a watering roll, and a draining roll.

However, in this type of device, the glue on the glue transfer roll is transferred to the glue target by moving the glue target between the glue transfer roll and the water washing roll and sending the paste between them. Therefore, when the object to be pasted is a relatively small label, etc., it is difficult to move the object itself, so that pasting cannot be carried out easily.

In addition, if the object to be glued is interrupted, the glue from the glue transfer roll will adhere to the washing roll, so a washing means consisting of a washing tank, a watering roll, and a draining roll is required to remove this. .

(Problems that the invention attempts to solve) This invention was created in view of the problems mentioned above and to solve them, and its purpose is to:
To provide a gluing device which can easily glue even if the object to be glued is relatively small and can omit a water washing means.

(Means for Solving the Problems) The gluing device of the present invention includes a holder that holds an object to be glued and is placed in place, a glue tank in which glue is stored, and a gluing device that is immersed in the glue in the glue tank. A glue roll is provided movably relative to the holder, and when not moving, a predetermined amount of glue from the glue roll is adhered to it, and when moving, it rolls away from the glue tank and the glue roll and along the object to be glued. It is characterized in that it is composed of a glue transfer roll that transfers the adhered glue onto the object to be glued.

(Function) The object to be pasted is held by the holder and fixed at a predetermined position.

When the glue transfer roll is not moving, a predetermined amount of glue is adhered to it.

When the glue transfer roll moves, the glue transfer roll comes into contact with the object to be pasted and rolls along it.

When the glue transfer roll rolls, the glue adhered thereto is transferred to the object to be glued and glued.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is a partially cutaway front view of a gluing device according to an embodiment of the present invention. FIG. 2 is a partially cutaway side view. FIG. 3 is a plan view.

The main parts of the gluing device 1 include a holder 2 and a glue transfer roll 3.

The holding body 2 holds the object A to be pasted and is placed in place.

In this example, a suction device is used to hold an object A to be pasted, such as a label, on the bottom surface by vacuum suction.
It is designed to be able to move up and down as well as move horizontally (swivel movement).

The glue transfer roll 3 is movably provided with respect to the holder 2, and when it is not moving, a predetermined amount of glue is applied to it, and when it is moving, it rolls along the object to be glued A and covers the glue that has been applied. This is to be transferred to adhesive material A.

In this example, the parts including this are front, middle, back,
A main body 4 having left, right, and bottom plates, a glue tank 5 that is movably provided on the bottom plate between the front and middle plates of the main body 4 and stores glue, and a yoke for raising and lowering the glue tank 5. A lifting mechanism 6 consisting of a yoke pin, a lever, etc.; a glue roll 7 rotatably provided on the front and middle plate of the main body 4 and immersed in the glue in the glue tank 5;

A rotary drive machine 9 consisting of a gear, a motor, etc. that rotates the roll 7 and the glue amount adjustment roll 8, and a front, rear, and right board that are provided so as to be movable laterally and vertically between the back, left, and right boards of the main body 14. A movable body 10 equipped with
and a lateral movement drive machine 1 which is provided on the rear plate of the main body 4 and includes an air cylinder or the like that moves the movable body 10 from side to side.
1, and a glue amount adjusting roll 8 which is rotatably provided on the front and rear plates of the movable body 10 and when the movable body 10 is not moving.
A glue transfer roll 3 that is rotated in contact with the upper side and that transfers glue to the glued object A when the movable body 10 moves, and the left and right plates of the main body 4 are installed so as to be able to move only up and down. A bar 12 that does not contact the glue transfer roll 3 when the movable body 10 is not moving and that contacts the upper side of the glue transfer roll 3 to roll it when the movable body 10 is moving, and a weight between the left and right plates of the main body 4. It is composed of a plurality of peeling threads 13 which are constructed so as to be constantly tensioned.

Next, the operation will be explained based on such a configuration.

The object to be pasted A is adsorbed and held on the lower surface of the holder 2, which is a suction device, and is horizontally moved to the opposite position shown in FIGS. 2 and 3, stopped, and then lowered.

At this time, the peeling thread 13 is pushed down to take on a tensioned state.

The glue roll 7 and the glue amount adjusting roll 8 are rotated clockwise and counterclockwise in FIG. direction, the glue tank 5
A predetermined amount of glue is applied to the glue transfer roll 3 via the glue roll 7 and the glue amount adjustment roll 8.

When the holding body 2 is lowered, the lateral movement drive machine 11 is activated and the movable body 10 is moved to the left from the non-movement position shown by the solid line in FIG.

When the movable body 10 is moved to the left, the glue transfer roll 3
is removed from the glue amount adjusting roll 8 and moved to the left while being rolled clockwise in FIG. 1 by the bar 12.

Then, the glue transfer roll 3 is rolled in contact with the lower surface of the object A to be glued, which is held by suction on the lower surface of the holder 2, and is prevented from over-rolling by the bar 12. The glue adhered to the glue transfer roll 3 is transferred to the lower surface of the object A to be glued.

When the lower surface of the object A is pasted, the holder 2 is raised to the opposing position.

At this time, the material to be glued A is completely peeled off from the glue transfer roll 3 by the peeling thread 13.

When the holder 2 reaches the facing position, the glue transfer roll 3 returns to the non-moving position.

After reaching the opposing position, the holder 2 is horizontally moved to the opposing position where the object (not shown) to which the material to be pasted A is to be pasted is placed, and then lowered and the suction is released. The glued object A is pasted on the object.
