Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for adjusting the position of a roll of film.

When forming a tube into a certain shape from a strip-shaped film, for example by welding, the original fabric is supported on an axis of the original fabric and is continuously fed to the forming section of the tube. And when one raw material is finished,
You can pull out the starting edge of the film from another waiting stock and bring it to the forming section, or
It is connected to the terminal end of the protoprimal end. However, in general, the side positions of each film supported by multiple film shafts are rarely the same, so in order to stably perform the forming process at the correct position, it is necessary to The position of the parts must match.

Conventionally, the above-mentioned position adjustment was performed while the film was being fed out by a position adjustment means provided for each film shaft. This conventional means, for example, as shown in FIG.
By moving the sleeve 5 axially fixed to the shaft body 4 via a bearing 41, the state of the forming part can be adjusted while feeding out the film for each film. It was hot. Therefore, when the original film is misaligned, the film fed out during the above-mentioned position adjustment is wasted, and the adjustment takes time, resulting in low work efficiency.

The present invention was developed in view of the above-mentioned circumstances, and after the initial web is set in the correct position,
The object of the present invention is to provide a fabric position adjusting device that allows the subsequent fabric to be set at the normal position while the fabric is on standby.

The present invention includes a plurality of fabric shafts, a support body that supports the plurality of fabric spindles, and a gauge that abuts the side surface of the fabric as described below.

Each web shaft supports the web rotatably around its axis, and is provided with position adjusting means for adjusting the position of the web in the axial direction.

The plurality of web shafts are supported in parallel to each other by one support body, and the support body itself is movable in the axial direction to adjust its position.

The gauge is attached to, for example, a support so that it can move in the axial direction and come into contact with the side surface of the original fabric. Once the gauge comes into contact with the side of one fabric, it moves the corresponding contact position onto the other fabric shaft, and contacts the gauge with the side of the fabric supported by the other fabric shaft. In order to at least match the positions of both original fabrics, it is possible to move within a plane perpendicular to the axis.

Next, the embodiment shown in FIG. 2 will be described. In the diagram, the parts common to the conventional example in Figure 1 are as follows:
The same reference numerals are given.

Reference numeral 1 denotes a film roll wound around a bobbin 11, and in this embodiment, one roll is attached to each of two roll shafts A and B.

Each fabric shaft A, B has a pair of cones 2, 2' on a sleeve 5 which is slidably mounted on the shaft 4. The cones 2, 2' are inserted through bearings 22, 22' and are rotatable on the sleeve 5, and one of the cones 2 is supported by a spring 21 from behind.
The bobbin 11 is firmly supported from both sides by the left and right cones 2 and 2'.

An adjusting screw 3 is axially fixed to the right end of the sleeve 5 via a bearing 32. The adjustment screw 3
has a threaded portion 31 at its tip, which is screwed into a threaded hole provided in the shaft body 4.

The shaft bodies 4, 4 of the original fabric shafts A, B are supported by shaft body receivers 61, 61 at both ends of the support body 6 in a parallel state and slidably, respectively. The shaft receiving parts 61, 61 are connected to the central boss part 63 by the arms 62.
The boss portion 63 is fixed to the central shaft 64 in the axial direction. A latching arm 7 whose tip is latched to the groove 41 of the shaft body 4 is slidably inserted onto the boss portion 63. A movable arm 71 that is moved in the axial direction by an adjusting means (not shown), such as a handle, is hooked into a groove provided on the outer periphery of the boss portion of the hook arm 7.

On the other hand, a gauge 8 is attached to the right end of the central shaft 64. The gauge 8 is connected to a cylindrical body 82 via a bearing 86 to a shaft 81 extending in the axial direction from a central shaft 64.
is rotatably attached, and a gauge body 83 is guided on the outside of the cylindrical body 82 so as to be slidable in the axial direction. A set screw 85 is attached to the gauge body 83 so as to fix it at an arbitrary axial position on the cylinder body 82 . The gauge body 83 has a contact portion 84 at its right end that is bent in a direction perpendicular to the axis and comes into contact with the side surface of the web 1 .

Next, a description will be given of how to adjust the position of the original fabric using the apparatus of this embodiment.

In this case, it is assumed that the original fabric on the original fabric axis A is in front, and the original fabric on the original fabric axis B is behind, and the side positions of the two do not initially match.

First, the positions of the side surfaces of both original fabrics are made to match using the gauge 8 according to the following procedure. First, gauge body 8
3 to bring the touch part 84 into contact with the side surface of one of the webs, for example, the web 1 of the web axis A, and after fixing that position with a set screw 85, the cylinder body 82 is rotated. The contact part 84 is turned over to the original fabric axis B side. Thereafter, when the adjusting screw 3 of the web shaft B is turned, the sleeve 5 and the cone 2 are moved in the axial direction. And original fabric axis B
When the side surface of the original fabric 1 contacts the contact portion 84, the adjustment screw 3 stops rotating. In this way, the lateral positions of both original fabrics completely match.

Next, the position of the original fabric A is adjusted to the optimal position with respect to the forming part. The procedure is to move the latching arm 71 in the axial direction using a handle (not shown) while carefully observing the forming state, and to set the shaft 4 of the raw fabric shaft to be latched thereto at the optimum position. Then, since the axial side positions of the fabrics on both fabric axes A and B completely match as described above, the fabrics on fabric axis B
The original web 1 is also set at the optimum position at the same time.

As the forming progresses, when the film on the fabric shaft A is finished, the film on the fabric spindle B is pulled out to the forming section. At this time, since the side position of the original fabric on the original fabric shaft B matches that of the original fabric on the completed original fabric axis A, there is no need to adjust the position with respect to the forming part again.

The next fabric is loaded onto the fabric shaft A in preparation for the end of the fabric shaft B side. Then, in the same way that the side positions of the fabrics on both fabric shafts A and B were initially made to match, the position of the fabric on the fabric axis A side is made to match that on the fabric axis B side. In this way, even when the web shaft is rotating, the positions of the webs can be maintained at the initially set regular positions one after another.

As described above, the present invention is provided with a gauge that shifts the side position of the web between a plurality of web axes, so once the initial web is set at the normal position, the web is Even during rotation, the subsequent film can be easily aligned and placed on standby, which simplifies and shortens the work, improves work efficiency, and eliminates wasted film. This greatly contributes to the effective use of materials. Furthermore, since the gauge directly contacts the side surface of the original fabric, even if there are variations in the winding position of the original fabric on the bobbin, this does not affect the adjustment operation in any way.

In addition, in the above-mentioned embodiment, there were two web shafts, but it is easily possible to further increase the number, and the gauge can be rotated in a plane perpendicular to the axial direction. It can also be achieved by linear movement within the same plane.
