BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ear holding device for preventing a processing defect due to a detachment of a tenter clip used in a finishing machine for a film, a cloth or the like.

[0002]

2. Description of the Related Art Conventionally, tenter clips used in finishing machines for films, fabrics and the like include, as shown in FIG.
While traveling on the endlessly arranged guide rail 12, the sheet-like material X is moved between the clip lever 13 and the clip base 14.
The sheet-like material X is expanded in the width direction while grasping both ears, and is released when the predetermined width is reached. There is a method in which an object is subjected to a drying process or the like, and the grip is released after the process is completed.

[0003]

However, in the tenter clip, the clip lever 13 rotates as shown by the arrow in FIG. 4, and the tip of the clip lever 13 descends from the inside onto the ear of the sheet-like material X. To grip the sheet. Therefore, for example, when the ears of the sheet-shaped material X are curled as shown in FIG. 5 or are raised as shown in FIG. Is pushed out, so that the ears of the sheet-like material X cannot be gripped between the clip lever 13 and the clip base 14, so-called clip detachment occurs. As a result, various adverse effects have been caused, such as a reduction in the width of the sheet-like material and a processing defect such as drying.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide an ear pressing device capable of reliably preventing a processing defect due to detachment of a tenter clip.

[0005]

In order to achieve the above-mentioned object, the invention according to claim 1 is characterized in that the sheet-like object ear is gripped prior to a gripping operation of a tenter clip which travels while holding the sheet-like object ear. An ear pressing device for pressing, comprising: a first pressing roller for pressing a sheet-shaped object ear portion; a rotating frame pivotally attached to a rotating shaft of the first pressing roller; The gist of the present invention resides in an ear pressing device comprising a second pressing roller connected in the moving direction of an object and a fixing member for fixing the first pressing roller at the position of the sheet-like object ear portion.

According to a second aspect of the present invention, the rotating frame and the second pressing roller are urged toward the sheet-like object side by a spring provided on the rotating shaft of the first pressing roller. The gist of the feature is the ear holding device.

[0007]

In the ear holding device according to the first aspect, prior to the operation of gripping the tenter clip, the first pressing roller fixed to the position of the sheet-like object ear portion by the fixing member is used. Is pressed so as to be flat. Further, a second pressing roller connected in the traveling direction of the sheet-like object via a rotating frame pivotally attached to the rotation shaft of the first pressing roller, and the sheet-like object ear portion is flattened together with the rotating frame. Is pressed so that

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of an ear holding device according to the present invention; As shown in FIGS. 1, 2 and 3, the ear holding device 20 of the present invention comprises a sheet-like material X.
A first pressing roller 21 pressing the ear portion of the first pressing roller 21, and a rotating frame 23 pivotally attached to a rotating shaft 22 of the first pressing roller 21.
And a second pressing roller 24 connected via a rotating frame 23 and the first pressing roller 21
And a fixing member 25 fixed to the ear position.

The fixing member 25 fixes the first pressing roller 21 at the position of the ear of the sheet-shaped material X, and is located at a position in front of the tenter clip 50 and along the traveling path of the sheet-shaped material X. Fixing plate 26 arranged above the ear position
And extending portions 27, 27 extending from both sides of the fixing plate 26.
And a U-shaped frame 29 attached to the end of the extending portion 27 by a bolt 28.

The first pressing roller 21 is connected to the fixing member 2.
Rotation shaft 2 attached between both ends of frame 29 in 5
2 is a roller that is rotatably mounted on the sheet material X and is fixed to the position of the edge of the sheet material X. The roller presses the ear of the sheet material X while rotating in accordance with the travel of the sheet material X, and It is designed to be flat. The fixing of the first pressing roller 21 to the edge of the sheet-like material X is performed by fixing the first pressing roller 21 to the fixing member 25 so that the first pressing roller 21 reliably presses the ear of the sheet-like material X. Extension part 27 of 26
The mounting angle between the frame and the frame 29 is appropriately adjusted, and these are tightened with bolts.

One end of a thin plate-like rotating frame 23 is pivotally attached to the rotating shaft 22 of the first pressing roller 21.
A rotating shaft 30 is attached to the other end of the rotating frame 23, and a second pressing roller 24 is rotatably attached to the rotating shaft 30. In this way, the second pressing frame 24 is connected to the traveling direction of the sheet-like material X via the rotating frame 23 after the first pressing roller 21, and these second pressing rollers 24 and The rotating frame 23 rotates vertically about the rotation shaft 22 of the first pressing roller 21 and presses the ears of the sheet-like material X by its own weight.

In the present invention, the second pressing roller 24 is used.
The material, diameter, width, material, thickness, and length of the rotating frame 23 are not particularly limited.
Since it rotates vertically about the first rotation shaft 22 and presses the ears of the sheet-like material X by its own weight, the material, diameter, etc. are determined so that these own weights are increased. Good to do.

The second pressing frame 24 and the rotating frame 23 are formed by a spring (not shown) provided on the rotating shaft 22.
Thus, the sheet X may be urged toward the ears. In this case, the ears of the sheet-like material X are connected to the first and second pressing rollers 21 and 24 and the rotating frame 23.
Is pressed with a larger pressing force due to its own weight and the urging force from a spring body (not shown).

As shown in FIG. 1, the ear holding device 20 according to the present invention is located at a position in front of the tenter clip 50 and at both ears along the traveling path of the sheet-like material X. However, as the number increases, the curl and bulge of the sheet-like material ear portion are more reliably corrected (pressed flat).

[0016]

According to the present invention, the above-mentioned structure is provided.
In the ear holding device described above, the first pressing roller fixed by the fixing member to the sheet-like object ear portion position before the tenter clip is gripped causes the sheet-like object ear portion to be flat. Is pressed. Further, a second pressing roller connected in the traveling direction of the sheet-like object via a rotating frame pivotally attached to the rotation shaft of the first pressing roller, and the sheet-like object ear portion is flattened together with the rotating frame. Is pressed so that For this reason, even when the ears of the sheet are curled or raised, the sheet is securely gripped between the clip lever and the clip table, so that the so-called clip does not come off. It is possible to prevent the occurrence of adverse effects such as a reduction in the width of the object and a processing defect such as drying.

In the ear pressing device according to the second aspect, the rotating frame and the second pressing roller are urged toward the sheet-like object side by the spring body provided on the rotating shaft of the first pressing roller. So that the ears of the sheet
The first and second pressing rollers, and the weight of the rotating frame and the urging force from the spring body are pressed with a larger pressing force. As a result, the flat shape of the sheet-like material becomes sharper, The reliability of the gripping operation of the tenter clip is further improved.
