Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tenter clip traveling device that can be applied to a tenter clip machine, a coaxial stretching machine, and the like.

FIG. 7 is a plan view of a conventional tenter clip traveling device, and FIG. 2 is a view taken in the direction of the ■ arrow in FIG. 1. Now, in Figures 1 and 2 showing the related mechanism of the tenter clip chain and its passage device, the clip body (/7) has two arms (1) (1) and the same arm (1) as in the conventional system. ) The lip lever (3) can be rotated around the upper branch (2)
and a clip stand (4').

Further, (5) is a roller chain for driving the clip body, and the roller chain (S) is bolted to the clip body (/7) via a mouth-shaped link plate (6).

The link plate (O) supports the stacking of the clip body,
It slides on the surface of a special bearing (9) attached to the rail (7).

Also, the arm (10) that protrudes behind the arm (1) of the clip body
) is provided with a roller (//) Cl2),
The rollers (//) (/ko) are installed so that the horizontal plane of the clip stand (da) coincides with the center of each roller.

A rigid roller guide rail (13) is provided between the rollers (/l) ('/2), and each roller (ii)
(i) is arranged with an appropriate gap from the roller guide rail (13). Roller guide rail (13)
is inserted into a groove provided in a member (/ll) that projects perpendicularly from the rail (7).

Also, (g) is liner, (/3) is main rail, (/6
) indicates a film. The film (1) is held between the clip lever (3) and the liner (g) and stretched in the width direction to a predetermined magnification. At this time, the clip body (/ri) is
Driven via a roller chain (S), the roller (//) (/
, 2) is guided by roller guide rails (13) held between the rollers.

However, the conventional device has a special bearing (9) that supports the weight of the clip body (/7) and provides the sliding movement when the clip body (17) runs, and a support that supports the stretching force of the film (/B). Rail (13) that serves as a travel guide for the clip
] are separate and independent members, which has the drawback of increasing the number of parts and the number of processing and assembly steps.

In addition, the horizontal tensile force C of the film (/6) and the roller (
The support is held by //), and the rollers (7, 2) prevent the moving clip body from wobbling laterally, but in both cases, the rollers ()/) C1/) and rollers Since the Uke is held only by (/ko), the roller (/l
) There was a problem with the durability of (/2).

Furthermore, the weight of the clip body (17) is the same as that of the special hair ring (
9) Since the catch has a sliding type structure, the clip body (
17) It was difficult to increase the running speed, and there was a drawback that smooth lubrication was required for the sliding movement.

The present invention has been proposed in order to solve the above-mentioned conventional drawbacks, and includes a tenter clip traveling device having a clip body that grips a film and travels, and a vertically arranged guide rail that guides the travel of the main body. The clip body is provided with rollers that absorb the body's own weight, lateral vibration, and horizontal tensile force, respectively, and the rollers are configured to move over the top and both sides of the guide rail, thereby facilitating assembly. The purpose of the present invention is to provide a tenter clip traveling device that is easy to assemble, reduces assembly man-hours, facilitates safety inspections, stabilizes running conditions, improves roller durability, and significantly increases running speed. be.

As explained in detail above, in the present invention, all the rollers are arranged on the upper part and both sides of the guide rail, so that the clip itself can be supported by its own weight, the traveling guide and the film can be moved smoothly. It is easy to assemble the bearings, which have the respective roles of holding the stretching force, and the number of assembly steps is reduced, as well as easy maintenance and inspection. Further, since three or more rollers are always used to guide the traveling of the traveling device such as the clip body, a stable traveling state is obtained and the durability of the rollers is also improved. Furthermore, if the weight is supported by the second roller of the bearing, the running speed can be greatly increased, and since there is no sliding surface, the lubricating oil management becomes easier.
