Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement in an adhesive application device that simultaneously and intermittently applies an adhesive to the front and back surfaces of a narrow thin plate-like steel strip, for example.

[Conventional technology]

When applying adhesive to the front and back sides of a thin, thin steel strip, conventionally the adhesive was applied by intertwining three rollers, or the thin, thin steel strip was passed through a jig filled with adhesive. , or apply adhesive. In the case of three rollers, the direction is not constant when the narrow thin steel strip coated with adhesive is discharged.
Lamination work takes a lot of time,
In addition, poor lamination occurred due to unevenness in the adhesive application.

Conventionally, an adhesive coating apparatus as shown in FIG. 2 has been used to apply adhesive to a thin, narrow steel strip.

This coating device is composed of a device 2 for setting a steel strip 1 in the shape of a narrow thin plate, a transfer device 3 for suctioning and transferring the steel strip 1 in the shape of a narrow thin plate, a shooter device 4, and an adhesive coating device 5. .

The setting device 2 uses a linear motor 8 to lower the table and sets the steel strip 1 in the form of a narrow thin plate. Thereafter, the linear motor 8 is raised by the amount determined by the photoelectric switch. In the transfer device 3, the rotary actuator 11 is reversed, and the suction device 10 works on the right side to suction the narrow thin plate-shaped steel strip 1, and the rotary actuator 11 is moved again.
is reversed and the narrow thin plate-shaped steel strip 1 is transferred. When it is reversed to the left, the suction device 10 breaks, and the narrow thin plate-shaped steel strip 1 falls off and is sent to the adhesive application roller section 5 through the shooter 13. In the adhesive application roller section 5, the adhesive 14 is supplied to the three rollers 15, and the adhesive is applied to the front and back surfaces by passing the narrow and thin steel strip 1 through it, and the adhesive is sent to the material alignment plate 16. .

However, even if the adhesive 14 is supplied to the area where the three rollers 15 are rotating, leakage occurs from both ends, so the frequency of supply is as short as about 25 sheets, resulting in a waste of adhesive. Furthermore, uneven coating occurs, resulting in lamination defects. 3 rollers 1
It is very difficult to adjust the gap in step 5, resulting in variations in the thickness of the adhesive, and the direction of the thin, thin steel strip discharged from the rollers to the material alignment box 16 is not constant, so this method is very common in lamination work. It takes time.

[Problem that the invention attempts to solve]

In view of this, the main purpose of the present invention is to propose an adhesive applicator of this type that eliminates uneven adhesive application and prevents lamination defects.

[Means for solving problems]

The present invention includes a means for raising a setting table on which a narrow thin plate-like steel strip 1 is placed, and a suction device 10.
rotary actuator means for sucking the narrow thin plate-shaped steel body 1 and transferring it onto the belt conveyor 17; The above-mentioned problem is solved by applying adhesive to the front and back surfaces of the narrow thin plate-shaped steel body 1 by placing it on a belt conveyor and passing through a pool of adhesive 24.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIG.

FIG. 1 is a schematic diagram showing an embodiment of the present invention.

The narrow thin plate-shaped steel strip 1 set by the setting device 2 is adsorbed by the suction device 10 of the suction device transfer device 3 and transferred by the transfer conveyor device 6. In the transfer conveyor device 6, the adhesive 24 is further transferred by the conveyor 17 and passes through rollers 19 and 20.
The thin, thin plate-like steel strip 1, which has been uniformly coated with an adhesive coating jig 23 on both the front and back surfaces, is pulled out with tweezers or the like to perform a lamination operation. Arranging the setting device 2, the suction transfer device 3, the transfer conveyor device 6, and the adhesive application jig 7 in parallel allows the continuous supply of the thin, thin plate-shaped steel strip 1 to the left in the figure. This contributes to the purpose of preventing variations in steel strip discharge and uneven coating.

[Operation of the present invention]

Next, the operation of the device of the present invention will be explained. First, the linear head motor 8 of the setting device 2 is lowered, and while the required number of narrow thin plate steel strips 1 are set, the linear head motor 8 is raised. When the narrow thin plate-shaped steel strip 1 is raised and the first narrow thin plate-shaped steel strip 1 is raised to a predetermined height by the action of the photoelectric switch, the linear head motor 8 is stopped and the setting is completed. When the narrow thin plate-shaped steel strip 1 is completely used up, the upper limit of the rise is activated and the entire device is stopped. Next, the adsorption transfer device 3
Then, the rotary actuator 11 repeats the reverse operation. When the arm 12 is reversed to the right, the suction device 10 works, and when the narrow thin plate-shaped steel strip 1 is suctioned, the arm 12 is reversed to the left, and the suction device 10 is cut and the narrow thin plate-shaped steel strip 1 is sucked. 1 falls. The arm 12 reversal speed can be varied by a speed control valve (not shown). The fallen steel strip 1 in the form of a narrow thin plate is sent to a transfer conveyor device 6. In the transfer conveyor device 6, a motor 22 (variable) is driven to rotate a roller 20 via a timing belt 18, thereby operating a conveyor 17 and rotating a roller 19 as well. A narrow, thin plate-shaped steel strip 1 is placed on a conveyor 17 that is in constant operation and transported. The transported narrow thin plate-shaped steel strip is bitten by rollers 19 and 20. roller 1
Adjust the bolt 21 so that the roller 9 is lightly pressed against the roller 20.
The pressure applied by the spring is always constant. The narrow thin plate-shaped steel strip 1 bitten by the rollers 19 and 20 and fed out is inserted into the adhesive coating jig device 7 and passes through the adhesive 24 accumulated between the rollers 25 and 26 and between the adhesive coating jig 23. Thin steel strip 1
Adhesive is applied to the front and back sides of the paper and discharged in the direction of the arrow. If the adhesive 24 is insufficient, it can be easily supplied from the upper part of the adhesive application jig 23. Even during cleaning, in the conventional example shown in Fig. 2, three rollers 1
5 has to be removed one by one, but in the present invention, the adhesive application jig 23 can be removed and attached with one touch, thereby eliminating waste during cleaning.

[Effects of this invention]

As described above, according to the present invention, there is a setting device for setting the steel strip in the shape of a narrow thin plate, a suction transfer device section for adsorbing and transferring the steel strip in the shape of a narrow thin plate, and a conveyor for moving the steel strip in the shape of a narrow thin plate. An adhesive applicator, which is composed of a transfer conveyor device that transfers the adhesive in a jig, and an adhesive coating jig section that collects the adhesive in a jig, passes it through a narrow thin plate steel strip, and applies the adhesive, Since they are arranged in the flow direction of the steel strip, it is possible to prevent uneven coating and poor lamination when discharging a narrow thin plate-shaped steel strip.

Furthermore, the frequency of replenishing adhesive is reduced compared to the conventional method, which has the effect of almost automatic operation being possible.

As mentioned above, the device of the present invention is extremely suitable for applying adhesives on both sides of various board materials, and can be used in a wide range of applications.
