Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a bookbinding adhesive applicator.

(Prior Art) As shown in FIG. 1, a conventional bookbinding adhesive applicator includes a spinner 3 equipped with an adhesive removal plate 2 around one periphery in an adhesive tank 1 of an appropriate shape, and an adhesive coating device. A coating roll 5 having a coating amount adjusting plate 4 on one periphery is rotatably arranged, and the coating roll 5 is rotated to deposit an adhesive 6 on its outer periphery. The coating amount adjustment plate 4 limits the layer to a certain amount, and by reciprocating the binding material 7 in the horizontal direction in the figure, the lower end of the adhesive 6 is applied to the coating roll 50. Apply the adhesive 6 in contact with the outer circumference of the hip joint, and scrape off the layer of the applied adhesive 6 with a spinner 3 so that it becomes uniform over the entire surface! It was l1ffl. However, in a bookbinding adhesive applicator having such a configuration from the outside, when the number of unnecessary materials 8 etc. is deposited on one outer periphery of the application roll 5, the number of unnecessary materials 8, etc.
As shown in Fig. 2, the adhesive is caught between the coating roll 5 and the coating roll 5, and prevents the adhesive from applying to the outer periphery of the coating roll 5 in this area. The adhesive 6 leaks in the application, and this causes the bound book to be finally bound and has the disadvantage of causing binding defects such as page omission in the sixth stage.

(Object of the Invention) The present invention has been made to eliminate the drawbacks of the conventional bookbinding adhesive applicator described above, and is to replace the adhesive application amount adjustment plate disposed around one area of the applicator roll. A roller for adjusting the indigo coating is arranged, and a groove of an appropriate shape is provided on the outer periphery of the roller, so that the indigo is coated on the outer periphery of the coating roll, is sandwiched between the coating amount adjustment plates, and is directed to the outer periphery of the coating roll. The object of the present invention is to provide a bookbinding adhesive applicator that removes unnecessary materials that may cause the adhesive to come off.

(Structure of the Invention) Below, the present invention will be described in detail based on embodiments shown in the drawings.

FIG. 3 is a schematic structural diagram showing an embodiment of a g-adhesive coating device for bookbinding according to the present invention.

A spinner 10 and a coating roll 11 are rotatably arranged in an appropriately shaped adhesive tank 9, and an adhesive removal plate 12 is provided around one periphery of the spinner 10.
As shown in FIG. 3, a roll 14 for adjusting the amount of adhesive applied is rotatably arranged around one side of the roll 14, the roll 14 having a seventh knurling 13 on its outer periphery.

The present invention is inspired by wR as described above. Next, we will explain its operation.

First, by rotating the application roll 11 in the adhesive tank 9, a certain amount of adhesive is applied to the outer periphery of the application roll 11, and the applied adhesive is limited to a certain amount of bone by the application amount adjustment roll 14, and during this rotation, the application roll 11 is rotated. The adhesive is applied to the upper part of the application roll 11 by moving the bound product 15 back and forth in the left and right directions as shown in the figure and the solid line, and the adhesive applied to the bound product 15 is applied to the top of the coating roll 11. The adhesive is scraped off with a spinner 10 to make it uniform over the entire surface, and any adhesive that has adhered to the outer periphery of the spinner 10 is scraped off with a removal plate 12 and returned to the adhesive tank 9. When applying adhesive on the upper outer periphery of the applicator roll 11 to the lower part of the bound product 15, how many unnecessary materials are placed on the outer periphery of the applicator roll 11?
Even if the unnecessary material moves in the direction of the coating amount adjusting roll 14 as the coating roll 110 rotates and tries to get caught in the location, the unnecessary material will be removed by the rotating coating amount adjusting roll 14. Since the outer periphery of the roll 14 is provided with a seventh knurl 13, this knurling 13 immediately removes the adhesive from the location so that the adhesive applied to the outer periphery of the applicator roll 11 is always uniform over the entire surface.

(Effect of the invention) The present invention is designed to operate like an assistant.
In place of the six adhesive coating amount adjustment plates that are conventionally arranged in a fixed manner around one area of the applicator roll, a coating amount adjusting roller 14 is arranged, thereby controlling the amount of adhesive applied to the outer periphery of the applicator roll 11. Since it is configured to limit the amount of adhesive and to remove unnecessary materials that are deposited on one outer periphery of the applicator roll 11, a certain amount of adhesive is always uniformly distributed over the entire surface of the upper outer periphery of the applicator roll 11. Therefore, when applying adhesive to the bound workpiece 15, there will be no leakage of adhesive, and binding defects such as page omissions can be almost completely prevented, thereby increasing the reliability of the device itself. It has the effect of being able to improve

It should be noted that there is no reason why the present invention should be limited to the above-mentioned embodiments. For example, the groove formed on the outer periphery of the σ-roller 14 for adjusting the amount of adhesive applied, that is, the seventh knurl 13, is
As shown in the figure, it may be replaced with a spiral groove 16. In this way, in order to remove unnecessary materials from the outer periphery of the coating roll 11, the unnecessary materials can be pushed into the spiral groove 16, and
It can also be removed by staying in the groove and automatically moving it to the side of the coating amount adjusting roller 14.
