Abstract

(57) [Summary] (Correction) [Purpose] To provide a new structure of an embossing machine that allows easy replacement of embossing rolls. [Structure] A gear that has been conventionally mounted on an embossing roll shaft 1a is mounted on a drive shaft 5 provided in a main body of a processing machine, and the embossing roll shaft 1a can be attached and detached via a drive shaft 5 and a gear coupling 6. . As a result, the embossing roll 1 can be easily replaced by simply removing the gear coupling 6 without having to remove the gear. The gear mounted on the drive shaft 5 meshes with the gear of the elastic roll shaft 2a to engage the elastic roll 2
Is rotated in the opposite direction, and a desired embossing is applied to the sheet-like material conveyed while being pressed between the embossing roll 1 and the elastic roll 2.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an embossing machine.

[0002]

[Prior Art]

 Various embossing machines have been used to impart a desired concavo-convex pattern to a sheet-like material such as paper, a synthetic resin film, or a veneer single plate, or to smooth the sheet.

FIG. 2 shows an outline of a conventional example of an embossing machine, and particularly shows a connection relationship between the embossing machine body and the embossing roll, and hatched parts are parts provided in the embossing machine body. It means that.

In this embossing machine, when a sheet-like material (not shown) is inserted and conveyed between the embossing roll 1 and the elastic roll 2, an uneven pattern corresponding to the female die of the embossing roll 1 is formed into a sheet shape. It is continuously formed on the object.

The embossing machine main body is provided with supporting means 3, 3, 4 and 4 for supporting bearings 1b, 1b and 2b, 2b mounted on the shaft 1a of the embossing roll 1 and the shaft 2a of the elastic roll 2, respectively. It is provided.

The embossing roll 1 is rotationally driven by a suitable driving means (not shown), and a gear 1c mounted on its shaft 1a and a gear 2c mounted on the shaft 2a of the elastic roll 2 are meshed with each other. The elastic roll 2 is driven to reversely rotate.

When it is necessary to repair or replace the embossing roll 1 due to wear due to long-term use, the shaft 1a of the embossing roll 1 is released from the driving means, and the supporting means 4 and 4 are lowered to move the elastic roll. The gear 1c is removed in the state that 2 is separated, and then the embossing roll 1 is lifted by a chain hoist or the like. The installation of the embossing roll after repair or replacement is performed in the reverse procedure.

[0008]

[Problems to be solved by the device]

 Since the embossing roll is a heavy object having a weight of, for example, 600 kg, it is not easy to repair or replace the embossing roll. In the conventional embossing technology, basically the same type of embossing roll is used for the embossing machine, and the cycle for repair or replacement is quite long, so workability at that time is a particularly problematic issue. It never happened.

However, in recent years, there has been an increasing demand for high-mix low-volume production in response to the diversifying needs of consumers, and in order to meet this demand, one embossing machine has several types of different uneven patterns. It is necessary to change the embossing roll frequently. In this case, the workability at the time of replacement as described above was a major obstacle.

[0010]

[Means for Solving the Problems]

 The present invention was devised with the object of solving the above-mentioned problems of the prior art, and the rotating shaft of the embossing roll is easily connected to the drive shaft provided in the main body of the embossing machine via the coupling means. Then, the drive gear mounted on this drive shaft and the driven gear mounted on the rotary shaft of the elastic roll mesh with each other to rotate the elastic roll in pressure contact with the embossing roll. The embossing machine is characterized in that it is configured to give a surface pattern corresponding to the surface of the embossing roll to the sheet-like object by inserting and conveying the sheet-like object.

[0011]

【Example】

 FIG. 1 schematically shows a configuration example of an embossing machine according to the present invention, and the same elements as those of the conventional example shown in FIG. 1 are designated by the same reference numerals. Since these do not require any particular explanation, the differences from the conventional example will be mainly described below.

Inside the main body of the embossing machine, there is provided a drive shaft 5 which is rotationally driven in a predetermined direction by an appropriate drive means (not shown), and the shaft 1 a of the embossing roll 1 has a gear coupling 6 interposed therebetween. The drive shaft 5 is detachably connected. A drive gear 7 is attached to the drive shaft 5.

In the illustrated example, the elastic roll 2 also has a similar structure. A driven shaft 9 provided in the main body of the embossing machine is equipped with a driven gear 9, and the driven shaft 8 has a gear coupling 10. It is detachably connected to the shaft 2a of the elastic roll 2 via the.

When the drive shaft 5 is rotationally driven in a predetermined direction, the driven shaft 8 is driven to rotate in the opposite direction through the engagement of the drive gear 7 and the driven gear 9. The rotational driving force of the drive shaft 5 and the driven shaft 8 is transmitted to the embossing roll shaft 1a and the elastic roll shaft 2a via the gear couplings 6 and 10, respectively, so that the embossing roll 1 and the elastic roll 2 have their respective circumferential surfaces. It is rotated in the opposite direction while being pressed against. Thus, a desired surface unevenness pattern corresponding to the surface unevenness of the embossing roll 1 is transferred to the sheet-like material which is sandwiched between the embossing roll 1 and the elastic roll 2 and conveyed.

This embossing machine is configured as described above, and since the bearings 1b, 1b are merely mounted on the embossing roll 1, the embossing roll 1 can be replaced easily. That is, when it is necessary to replace the elastic roll 2, the supporting means 4 and 4 for supporting the elastic roll 2 are processed to release the pressure contact state with the emboss roll 1, and then the emboss roll shaft 1a is connected to the drive shaft 5. Operate the gear coupling 6 to release the connection, and hoist the embossing roll 1 to carry it. To install a new embossing roll, reverse this procedure.

The replacement work of the elastic roll 2 can be easily performed in the same manner.

[0017]

[Effect of the device]

 According to the present invention, the drive shaft and the drive gear are provided in the main body of the embossing machine and the drive gear is not attached to the embossing roll itself unlike the conventional product, so the coupling means is operated to operate the embossing roll. The embossing roll can be removed from the embossing machine simply by disconnecting the rotary shaft from the drive shaft on the main body side.

Therefore, even when a plurality of types of embossing rolls having different uneven patterns are exchanged and used as needed, the exchange work can be easily performed.
