TECHNICAL FIELD The present invention relates to a multi-spindle turret winder, and more particularly to the above-mentioned multi-spindle turret winder capable of winding both upper and lower winds.
The present invention relates to a winding direction automatic switching device and a winding automatic switching method for automatically switching and changing the winding direction of a sheet-like material wound on the winding machine.

(Prior Art) Generally, in the roll winding of a sheet-shaped material by a multi-axis turret winding machine, a sheet-shaped material supplied to the side of the winding core tube is wound so as to be directed upwardly of the winding core tube. There is a so-called under-winding which is wound so as to be directed toward the lower side of the winding core tube. However, in the conventional winding machine, the winding direction is usually limited to either one. Those that can be wound on both sides have not been provided yet.

(Problems to be solved by the invention) Therefore, even if such a conventional multi-axis turret winding machine has the same sheet-like material, the upper winding roll and the lower winding roll cannot be wound by separate winding machines. It did not disperse, which was a problem in terms of work efficiency and economics.

In view of the above situation, the present invention addresses this situation and intends to perform both windings with a single winding machine, and in particular, an automatic winding direction switching capable of appropriately switching between upper winding and lower winding. The purpose is to find a device and to improve the work efficiency and economical efficiency by installing this device together.

(Means for Solving the Problems) That is, the present invention, which is adapted to the above object, firstly relates to a winding direction automatic switching device of a multi-axis turret winding machine capable of winding both sides as a basic feature. A guide roller for guiding a traveling sheet, which is attached to a front and rear slidable auxiliary machine frame arranged at the front of the multi-axis turret winder at substantially the same height as the winding position of the winder, and the guide. The base is rotatably supported by the central axis of the roller, and the first and second arms are branched and extended in two directions at a predetermined angle from the base toward the winding position side, and the tip ends thereof. The first and second course changing rollers respectively, and the course changing roller for moving the sheet-like material through both the changing rollers; the winding position of the multi-axis turret winder and the course changing roller. Arranged upside down with the winding position in the middle of the rotation range The upper and lower touch rollers are supported by one end of the arm, the other end of the arm is pivotally supported, and the other end of the winding position and the retracting position are supported without interfering with other rollers and the course changing roller with the support shaft as a fulcrum. It consists of an upper winding touch roller and a lower winding touch roller that are selectively rotatable between them, and cutting blades that are arranged above and below, respectively, and the auxiliary machine frame corresponds to the winding weight of the winding roll in the winder. It is slidable in the front-back direction, and the course changing roller, the upper and lower touch rollers, and the cutting blade are controlled by a control mechanism.

Further, the invention according to claim 2 is a method of using the above-mentioned device to specifically perform winding and automatic switching of the winding direction,
The upper winding touch roller is brought into contact with the winding core tube of the multi-axis turret winding machine, and the sheet-like material is wound from the upper surface of the guide roller to the lower surface of the first course changing roller or the upper surface of the second course changing roller and the upper winding. While passing through the lower surface of the touch roller to the winding core tube and performing the upper winding, the touch roller for lower winding is brought into contact with the winding core tube of the multi-axis turret winding machine so that the sheet-like object is placed above the guide roller. The lower core of the first course changing roller or the upper surface of the second course changing roller and the upper surface of the touch roller for lower winding are brought to the winding core tube to perform the lower winding, and the rotation of the roller for changing the course and the touch for upper winding are performed. Evacuation of rollers,
It is characterized in that the winding direction is automatically changed by selectively actuating the contact with the winding core tube and the contact and retraction of the lower winding touch roller with the winding core tube according to the control means.

(Operation) In the winding direction automatic switching device and method of the present invention having the above-described structure, during the upper winding, as described above, the course changing roller rotates in the predetermined direction and the upper winding touch roller comes into contact with the winding core tube. Then, the sheet material is wound around the touch roller for upper winding via the second course changing roller. At this time,
The second course changing roller is positioned above the upper-winding touch roller by the upward rotation, and the sheet-like material is the second roller.
Is supplied from below to the winding core tube at the winding position from the upper surface of the course changing roller through the lower surface side of the upper winding touch roller.
Then, the sheet-like material is wound into the upper winding by the rotational driving of the winding core tube in the upper winding direction.

On the other hand, in the underwinding, the course changing roller is rotated downward in the opposite direction to the above, and the underwinding touch roller is brought into contact with the winding core tube, so that the sheet-like material is wound under the first course changing roller. The first course changing roller is positioned below the lower winding touch roller at this time, and after supporting the sheet-like material on the lower surface side of the first course changing roller, the lower winding touch roller Wrap it around the top side. Then, the sheet-like material is supplied to the winding position from above, and the lower winding roll is obtained by rotating the winding core tube in the lower winding direction.

Then, when switching the winding directions of the upper winding and the lower winding to the lower winding and the upper winding respectively, first, the course changing roller is rotated to rotate the touch roller in contact with the winding core tube. After evacuating the sheet-like material from this position, rotate this touch roller to separate it from the winding core tube, and then rotate the course changing roller in the opposite direction to the direction of the other touch roller. By retracting the sheet-like object from the moving range and bringing a new touch roller into contact with the winding core tube, winding in the direction opposite to the previous direction is possible.

It is possible to obtain winding rolls for both upper winding and lower winding extremely efficiently without using a separate winding machine.
It can be easily used together with existing multi-spindle turret winders, and it is expected that the multi-spindle turret winder will be more versatile and will be put into practical use.

Moreover, since the secondary machine frame can slide back and forth and slides according to the winding, the upper touch roller arm and the lower touch roller arm arranged on the secondary machine frame have the same posture regardless of the winding diameter. Is maintained and is rotated and selectively used only when the winding direction is changed. As a result, the winding diameter of the roll is not restricted by anything other than the sliding range of the secondary machine frame.
