Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a winding device for webs (flexible strips) of thermal paper for color printing, plastic films, metal films, and the like.

[Prior Art] Conventionally, for example, three types of webs W1 to W3 are successively connected endlessly using a connecting tape, and each set of webs W1 to W3 is
3 in succession, and each set of webs W1 to W3 is wound in small order on each pair of primary winding bobbin and secondary winding bobbin, etc., the preceding web (Wl) After winding on the first winding bobbin, a secondary winding bobbin is connected to the winding end of the preceding web (winding end of Wl), and the winding start end of the succeeding web (winding start end of W3) is connected to the winding end of the preceding web (winding end of W1). The process of separating the web from the preceding web and winding it onto another new primary winding bobbin is repeated.

[Problems to be Solved by the Invention] However, in the conventional web winding method, the above-mentioned web winding operations, namely, the transportation of the primary winding bobbin and the secondary winding bobbin, and the winding of the web are difficult. The winding start end of each web is joined to the primary winding bobbin, the winding end end is joined to the secondary winding bobbin, and the leading and trailing webs are separated by hand, which improves workability and productivity. low gender.

In addition, when the separation position of the leading web and the trailing web is located at the end of the winding of the leading web, the connecting tape remains at the winding start end of the trailing web, and when the trailing web is wound, the connecting tape is unwound. Since the winding thickness on the core side is locally increased, there is a risk that the winding appearance of the winding bobbin may deteriorate, such as uneven winding.

On the other hand, if the separating position of the leading web and the trailing web is located at the winding start end of the trailing web, the connection tape remains and is exposed at the winding end of the leading web, impairing the winding appearance of the winding bobbin.

The present invention connects a leading web and a trailing web with a connecting tape, winds the leading web onto a primary winding bobbin, joins a secondary winding bobbin to the end of the winding of the leading web, and connects the leading web with a connecting tape. To improve workability and productivity and to improve the winding form of a winding bobbin when the winding start end of a web is separated from a preceding web and wound onto another new primary winding bobbin.

[Means for Solving the Problems] The present invention connects a portion corresponding to the winding end of the preceding web to a portion corresponding to the winding end of the trailing web using a connecting tape, and continuously feeding out the leading web and the trailing web. The preceding web 1
After winding onto the next winding bobbin, a secondary winding bobbin is joined to the winding end of the preceding web, and the winding start end of the succeeding web is cut off from the preceding web to start another new primary winding. In a web winding device that repeatedly winds the web onto a bobbin, the web winding shaft that holds the primary winding bobbin and the web winding shaft are rotationally controlled to wind the web onto the primary winding bobbin. , a winding control unit that can set a connecting tape connecting the leading web and the trailing web to a cutting position;
A connection tape suction unit that can chuck the secondary winding bobbin and another new primary winding bobbin and set each of these bobbins on both sides of the above-mentioned cutting work position in the web pass line, and can suck the connection tape. a transfer device that sets the above-mentioned cutting tape at the cutting position, and a transfer device that holds the leading web and the trailing web on both sides of the connecting tape set at the cutting position, respectively.
A web pressing device presses and joins each of the next winding bobbin and the primary winding bobbin, and the leading web and trailing web on both sides of the connecting tape set at the cutting work position are joined to each of the above bobbins by the pressing device. and a cutting device for cutting the portion sandwiched between the two portions.

[Function] According to the present invention, the transfer device transfers the primary winding bobbin and the secondary winding bobbin, the winding control unit winds the web, and the transfer device and the web pressing device control the winding start end of each web. The joining to the primary winding bobbin, the joining of the winding end to the secondary winding bobbin, and the separation of the leading web and the trailing web by the cutting device are automatically performed. In addition, since the leading and trailing webs are held by the web pressing device at the side edges of the cutting portion and cut by the cutting device, the webs can be cut quickly and reliably along the predetermined cutting line. , it is possible to improve the workability of separating the preceding web and the following web. Further, the connection tape cut off by the cutting device is adsorbed by the connection tape adsorption section of the transfer device, so that it can be automatically discharged to an appropriate location. Therefore, the workability and productivity of web winding can be improved.

Further, the leading web and the trailing web are separated from each other by using the repositioning of the winding end of the leading web and the winding start end of the trailing web, which sandwich the connection tape, as the cutting position. Therefore, the connecting tape is used only for the continuous unwinding of the leading and trailing webs, and does not remain on the side of the winding bobbin that winds the leading web or the winding bobbin that winds the trailing web. . This prevents the connecting tape from remaining at the end of the winding of the preceding web and being exposed, and the connecting tape from remaining at the beginning of the winding of the succeeding web, which locally increases the winding thickness on the core side. , the winding appearance of the winding bobbin can be improved.

Then, the subsequent web (end tape W3) is automatically separated. In addition, since the leading and trailing webs are cut by the web cutting device 72 while holding the cut side edges of the leading web and the trailing web by the web pressing device 71, these webs can be cut quickly and reliably along a predetermined cutting line. This improves the workability of separating the leading web and the trailing web.

Furthermore, the connection tape 38 cut by the cutting device 72 is adsorbed by the connection tape adsorption section 75 of the transfer device 70, so that it can be automatically discharged to an appropriate location. Therefore, the workability and productivity of web winding can be improved.

Further, the leading web and the trailing web are separated from each other by using the repositioning of the winding end of the leading web and the winding start end of the trailing web, which sandwich the connecting tape 38, as the cutting position. Therefore, the connecting tape 38 is used only for the continuous unwinding of the leading and trailing webs, and does not remain on either the winding bobbin for winding the leading web or the winding bobbin for winding the trailing web. As a result, a portion of the connecting tape 38 may remain on the winding end side of the preceding web and be exposed, or a portion of the connecting tape may remain on the winding start end side of the succeeding web, thereby locally increasing the winding thickness on the core side. There is no winding bobbin 17A, 17B.
The appearance of the roll can be improved.

[Effects of the Invention] As described above, according to the present invention, a leading web and a trailing web are connected by a connecting tape, and the leading web is wound onto a primary winding bobbin, and the leading web is wound at the end of the winding end of the leading web. This improves workability and productivity when joining the secondary winding bobbin and separating the winding start end of the trailing web from the leading web and winding it onto another new primary winding bobbin. The appearance of the roll can be improved.
