Abstract

(57) [Summary] [Purpose] The volume of the glue reservoir grooves carved on the surface of the glue roll can be freely selected. [Structure] The adhesive roll 1 is characterized in that the glue reservoir grooves 12 are provided in a plurality of attachments 15 which are removably attached to the outer circumferential surface of the glue roll 1, each with a different amount of glue transferred.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is applied to the gluing device used in the folder gluer of the box making machine that manufactures cardboard boxes. related.

0002

[Conventional technology]

A conventional example of a gluing device will be explained with reference to FIGS. 4 to 6. A gluing roll 1 is disposed above the gluing part into which the gluing part is inserted, and a gluing roll 1 is received on the underside of the gluing roll 1. A supporting roll 2 is provided, and the receiving roll 2 is connected to drive sprockets 3 and 4 as shown in FIG. The glue 7 in the glue tank 6 is rotated through the drive chain 5 and pumped into the glue pump 8. The surface of the glue roll 1 when supplied to the applicator 11 via the pipes 9 and 10 A certain amount of glue transferred to the glue reservoir groove 12 carved on the surface as shown in FIG. 6 is transferred to the glue roll 1. and a structure that further transfers onto the corrugated sheet when the corrugated sheet a comes into contact with the corrugated sheet a. It has become. In addition, the glue 7 excessively supplied to the applicator 11 passes through the glue pipe 13. The glue is then returned to the glue tank 6.

[Problem that the idea aims to solve]

In the conventional gluing device, the amount of glue used to bond corrugated cardboard sheets is The intended use as a cardboard box is determined by the volume of the glue grooves cut into the attached roll. Although it is necessary to change the amount of glue depending on the target, the glue roll is easy to apply to the glue device. Because it is difficult to install and remove, one type of glued roll is always used during actual manufacturing. are doing. As a result, gluing defects occur due to excess or lack of glue, resulting in defective products or machine stoppages. A problem has arisen.

0004 The present invention was developed in order to address the above-mentioned problems. The purpose is to use adhesive attachments depending on the intended use of the cardboard box. Easily transfer the optimum amount of glue to reduce gluing defects and improve reliability. To provide a gluing device.

[0005]

[Means to solve the problem]

1 to 3, which correspond to embodiments of the configuration of the present invention to achieve the above object, are shown in FIGS. To explain using the present invention, glue reservoir grooves 12 are carved on the surface of the introduction path of the corrugated cardboard sheet a. The glued roll 1 and the receiving roller are sandwiched between the cardboard sheet a and the bottom of the glued roll 1. In the gluing device provided with the gluing roll 2, the gluing roller Glue is applied to each of the plurality of attachments 15 that are removably attached to the outer circumferential surface of the tool 1. It is characterized by providing different amounts of transfer.

[0006]

[Effect]

And this invention uses the above-mentioned means to create many different ways to use cardboard boxes, depending on the purpose of use. If a certain amount of glue is required, an attacher with glue retaining grooves engraved with the amount of glue transferred according to the request is available. This can be done simply by attaching the adhesive to the glue roll.

【Example】

An embodiment of the present invention will be described below based on FIGS. 1 and 2. Reference numbers 1 to 1 in the figures will be explained below. 3, the same parts as those in the conventional example shown in FIGS. 4 and 5 mentioned above are given the same reference numerals. The explanation will be omitted. In the present invention, the gluing roll 1 is fixed to the rotation shaft of the roll body 1a. is detachably attached to the outer periphery of the roll main body 1a and is secured to the roll by a retaining screw 14. A cylindrical attachment 15 fixed to the main body 1a. The glue reservoir groove 12 was carved in the groove 15.

[0008] The attachments 15 include a plurality of adhesive grooves 12 with different amounts of glue transferred. The amount of glue can be selected depending on the purpose. FIG. 3 shows another embodiment of the present invention, in which the attachment 15 is the roll body 1a. It was formed into a band shape that was wrapped around the outer periphery with an adhesive 16 interposed therebetween.

[0009]

[Effect of the idea] In this way, according to the present invention, the glue reservoir grooves carved on the surface of the glue roll are The glue is transferred to multiple attachments that are removably attached to the glue roll. Since the transfer amount is different, the amount of glue transferred can be easily changed. Adhesion defects caused by excess or deficiency can be reduced, and maintenance can be improved by using adhesive attachments. This has the effect of making it easier to maintain and significantly reducing costs for the entire production line. Ru.
