Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape attaching device suitable for use in attaching a tape to, for example, a linear guide device.

[0002]

2. Description of the Related Art In a manufacturing apparatus, for example, a linear guide device is provided for driving a driven body such as a table. In a linear guide device, a slider to which a table or the like is attached is arranged so as to be able to linearly move along a guide rail extending in the axial direction via a number of rollable balls. The guide rail is fixed to the base by inserting and tightening mounting bolts into a plurality of bolt holes provided through the body.

FIG. 1 is a perspective view showing an example of a linear guide device. In FIG. 1, a slider 2 is straddled so as to be movable on a guide rail 1 extending long in the axial direction.
The insertion holes 5 of the bolts 4 for attaching the guide rail 1 to a base (not shown) are provided at a predetermined pitch in the longitudinal direction of the rail.
The guide rail 1 is formed as a through hole that passes from the upper surface to the bottom surface and has a seat surface for the head of the bolt 4.
The bolt 4 is screwed into a screw hole provided in the base through the bolt insertion hole 5.

Ball rolling grooves 11 are formed in three rows on both sides of the guide rail 1 in the axial direction, and the ball rolling grooves 11 are formed on inner surfaces of both sleeves of a slider body 2A of the slider 2. A ball rolling groove (not shown) facing the groove 11 is formed. A large number of balls (not shown) are rotatably loaded between the two ball rolling grooves facing each other, and the slider 2 moves on the guide rail 1 with low friction by utilizing the rolling of the balls. It moves in the axial direction.

In such a conventional linear guide device,
Dirt, dust, chips, etc. accumulate on the upper surface of the guide rail 1,
When this enters the path of the rolling ball, the smooth rolling of the ball is hindered, which may hinder the smooth movement of the slider 2. That is, the improvement of the guide rail dust-proof seal performance in the linear guide device is an important requirement in the characteristics of the linear guide device. Therefore, wiper seals for dust prevention are generally attached to both ends of the slider 2. It is a target.

When the guide rail 1 is mounted on the base, the mounting bolt 4 is generally inserted into the bolt insertion hole 5 opened on the upper surface of the guide rail 1 and tightened. It sinks into the hole 5. As a result, the location of the bolt insertion hole 5 on the upper surface of the guide rail 1 becomes concave. Then, the dust and the like accumulated in the depressions pass through the dust-proof wiper seal and enter the inside of the slider 2, and the sealing function of the wiper seal is impaired. Therefore, a plug is inserted into the recess of the bolt insertion hole 5.

However, plugging in such a manner that the step with the periphery of the bolt insertion hole 5 is completely eliminated requires a large number of steps and increases the cost. The edge often has a slight step. Therefore, the wiper seal is caught on this step,
There is a problem that the seal is damaged and the sliding resistance of the slider 2 fluctuates. It is conceivable that the opening edge of the bolt insertion hole 5 and the outer edge of the plug head are chamfered in advance to make it difficult to catch, but there is also a possibility that dust may accumulate in the recess formed by the chamfering.

[0008]

Therefore, instead of plugging the bolt insertion hole 5, a metal tape with an adhesive is attached to the upper surface of the guide rail 1, and a step caused by the formation of the bolt insertion hole 5 is formed. There are attempts to get rid of it. However, since the guide rail 1 is a long object that is long in the longitudinal direction,
It takes time and effort to attach a metal tape in parallel to the upper surface, and there is a problem that the working efficiency is poor. Also, if a metal tape having a relatively low rigidity is manually applied to the upper surface of the guide rail 1 while pressing it with a finger, a hollow is formed only above the bolt insertion hole 5, which may cause the accumulation of dust. There is.

Accordingly, an object of the present invention is to provide a tape attaching device such as a linear guide device, which can attach a tape more easily on a guide rail, for example.

[0010]

According to the present invention, there is provided a tape attaching device for attaching a tape to a guide rail of a linear guide device, the tape attaching device being capable of moving relative to a main body and both side surfaces of the guide rail. And a mounting portion for applying a pressing force to the tape disposed between the main body and the guide rail toward the guide rail and restricting a mounting position.

[0011]

According to the tape mounting device of the present invention, in a tape mounting device for mounting a tape on a guide rail of a linear guide device, a movement guide portion abutting movably relative to both sides of the main body and the guide rail. And a mounting portion for applying a pressing force to the tape disposed between the main body and the guide rail toward the guide rail and regulating a mounting position. By moving the moving guide portion, the mounting portion can press the tape against the guide rail with a substantially uniform pressing force, and the mounting position can be regulated to be parallel. The tape may be a thin plate made of metal or other material, and it does not matter whether an adhesive or a pressure-sensitive adhesive is previously applied to a surface that comes into contact with the guide rail.

It is preferable that the moving guide has a side wall extending from the main body toward both side surfaces of the guide rail, and the mounting section is provided when the tape mounting device is mounted on the guide rail. Preferably, a groove extending parallel to the guide rail (or the inner side surface of the side wall portion) and substantially equal in width to the tape is formed facing the upper surface of the guide rail. Further, it is preferable that the depth of the groove is smaller than the thickness of the tape, since an appropriate pressing force can be applied between the tape and the guide rail.

Further, a concave groove is formed on the upper surface of the guide rail, and when a tape is mounted in such a groove,
The mounting part may be a convex part. It is preferable that the mounting portion has a tapered surface with a gradient as it goes outward, since a sharp bend or the like of the tape can be prevented.
