Description

  The present invention mainly relates to an in-turret touch roller device in a multi-axis turret type winder.

  Conventionally, in a multi-shaft turret type winder, the web is wound as a take-up roll by rotating the take-up shaft with a motor or the like to apply tension to the web with respect to the web wound around the take-up shaft. Since air is entrained between the outer peripheral surface of the take-up roll and the web entering the take-up roll, the touch roller is wound to prevent this air entrapment and adjust the amount of air entrained. It is provided at a position where the web enters on the surface of the take-up roll, and the pressure in contact with the take-up roll of the touch roller is adjusted.

  FIG. 3 shows an example of a conventional turret type winder provided with the above touch roller. The first touch roller 3 is placed on the upper side of the upstream winding shaft 4 of the turret board 1 and the turret frame (outside the turret board). (Not shown) is rotatably supported by an arm 7 having a rotation center 6 so as to be in contact with and away from the take-up shaft 4, and the fed sheet S passes through the guide roller 2 and the first touch roller. 3 is wound around the winding shaft 4 as a winding roll R, and after full winding, the pressure contact of the first touch roller 3 is released to rotate the winding shaft 4 in the turret turning direction indicated by the arrow. It has become.

  However, in this apparatus, since the winding shaft 4 is separated from the first touch roller 3, the second touch roller 5 supported outside the turret is in pressure contact with the turret to prevent the winding roll R from being unwound. In addition, a method for preventing air entrainment has been practiced.

  4 and 5 show an example of a turret type winder provided with such a second touch roller, showing the pressure contact state of the second touch roller 5 supported outside the turret before and after turning. Yes.

  Since the second touch roller 5 of this apparatus follows the turret turning only when the turret is turning, it cannot be provided at a position facing the first touch roller 3 and the winding shaft 4 is thin or If the pressure contact force is large, the winding shaft will bend and it will not be possible to wind with good quality.

On the other hand, FIG. 6 shows a second touch roller 5 that is also supported outside the turret. This touch roller 5 is supported outside the turret, presses against the take-up shaft 4 from below, and faces the first touch roller 3. However, since it is supported by an arm 9 having an elevating center 8 outside the turret, the turret rotation of the winding shaft 4 cannot be stably followed after the start of the turret rotation. Has the problem of leaving.
Description of Japanese Patent Publication No. 06-001500

The present invention pays attention to various problems of the conventional touch roller device as described above, and in particular, by providing a support slide rail of the turret touch roller on the turret board and finding a suitable configuration of the second turret related thereto. The first touch roller and the second touch roller face each other in pressure contact, and the first touch roller is detached while the turret is turning, but the second touch roller is always in pressure contact, so that the touch roller winding The purpose is to improve the winding quality of the web in the take-up machine.

  That is, according to the present invention suitable for the above-mentioned purpose, in the multi-axis turret type winder, the first touch roller is brought into contact with the upper part of the upstream side winding shaft of the turret board, and the second touch is made on the lower part of the winding shaft. When the web is wound around the winding shaft by contacting the roller, the first touch roller is supported by the outer frame of the turret so as to be rotatable through the arm, while the second touch roller is provided in the turret. It is a turret device in a turret in a turret type winder that is slidably mounted on a support rail and can always be brought into contact with a winding shaft even when the turret is turning.

Above all. Particularly receiving a second touch roller in the form of two rollers which juxtaposed, with one winding shaft bottom I two rollers to touch the roller of the winding shaft top, stable winding shaft core It is an important feature to make it hold .

  In the multi-axis turret type winder equipped with the touch roller device according to the present invention, the second touch roller is slidably mounted on a support rail provided in the turret board, so that the turret can be swung. Since the contact pressure position of the winding shaft and touch roller does not change and is always pressed at the same position, it can be widely applied from thin plastic films to thick films, and good results in winding quality are obtained. This is especially effective when it is necessary to wind the wire tightly. In addition, when slitting and winding immediately before winding a wide film, it is always advantageous to press the same position at the same position to stably wind the narrow film while turning the turret.

  Hereinafter, specific embodiments of the apparatus of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 shows a state of the touch roller device according to the present invention before the turret is turned, and FIG. 2 is a view showing a state of the device after the turret is turned. In these drawings, 1 is a turret board. The first touch roller 3 is formed at the upper part of the upstream winding shaft 4 and the second touch roller 5 is formed at the lower part of the winding shaft 4 by two rollers in the illustrated example, and they are attached in contact with each other. Then, the fed sheet S passes through the guide roller 2 and is wound as a winding roll by the winding shaft 4 under the pressure of the first touch roller 3.

  In the above configuration, the first touch roller 3 is rotatably supported by an arm 7 having a rotation center 6 on a turret frame (not shown) as is well known. A second touch roller 5 is integrally supported in the lower part of the winding shaft 4 and is mounted in the turret so as to receive the winding shaft 4.

  The device of the present invention is particularly characterized in the attachment of the second touch roller 5. In the conventional method, as shown in FIG. 6, the fulcrum 8 is provided outside the turret and the fulcrum 8 is the center of rotation. However, in the present invention, the second touch roller 5 is slidably mounted on a support rail 10 provided in the turret board 1 and is always wound even when the turret is turning. Contact with the spindle 4 is possible. Therefore, when the turret board 4 turns with full winding, the second touch roller 5 located under the take-up roll R wound around the take-up shaft 4 slides within the support rail 10 along with the turn. It turns together with the take-up roll R, and the position changes to the upper part of the take-up roll R after the turn. However, the second touch roller 5 is slidably held by the support rail 10 fixed to the turret board 1 and is always in pressure contact with the outer periphery of the take-up roll R even if it is located at the upper part of the take-up roll. Accordingly, during this time, the contact state between the winding shaft 4 and the second touch roller 5 does not change, and an appropriate winding hardness can be obtained without involving an air layer.

  Thus, the fed sheet S is received by the first touch roller 3 from the upper part and the second touch roller 5 from the lower part, and the winding is continued, and the winding roll R reaches full winding and the turret board When 1 is turned by a known turning drive device (not shown), the first touch roller 3 is separated from the take-up roll R by the turning arm 7 supported on the outer frame of the turret, while the second touch. The roller 5 slides on the support rail 10 provided in the turret board 1 and rotates together with the turret board 1 so that the full winding is performed without changing the contact between the winding roll R and the second touch roller 5. The sheet S is stretched between the full winding roll R and the upstream winding shaft 4 by changing the position to the upper side of the roll R, and when this is cut by the cutter 11, a new winding shaft core is formed. While the cut edge of the sheet is wound, Winding roll will be migrated to the release into the turret plate out as is known.

In the above configuration, in particular, the present invention has the second touch roller 5 in the turret board in parallel with two rollers as shown in the figure, so that one touch roller on the upper part of the winding shaft is The axis of the take-up shaft is more stabilized by the two touch rollers on the receiving side, and good results can be obtained.

  As described above, the turret device of the present invention can be widely applied from a thin plastic film to a thick film, and can also be used effectively when it is necessary to wind hard such as a non-woven fabric. Even when the film is slit and wound immediately before the film is wound, the narrow film while turning the turret can be stably wound.
