  In the present specification and claims, “winding start side” and “winding end side” are terms representing the orientation of the sheet material winding device according to the present invention, and are referred to as “winding start side”. Represents the side on which the sheet material starts to be wound in the axial direction of the tubular material, and “winding end side” represents the side on which the sheet material has been wound in the axial direction of the tubular material.

In the present invention, in particular, the support means includes a support frame provided on a base, a support shaft supported by the support frame, a support shaft provided on the support shaft, and a cylindrical inner surface at an end of the cylindrical material. And a chuck portion to be held.

The present invention is characterized in that the support frame is provided so as to be capable of reciprocating in the axial direction of the cylindrical member.

  The sheet material winding method according to the present invention includes a sheet material supply unit that supplies the sheet material to the outer peripheral surface of the axially rotating cylindrical material obliquely with respect to the axial direction of the cylindrical material by the sheet material supply unit. The sheet material is spirally wound around the outer peripheral surface of the tubular material by relatively moving the tubular material in the axial direction,
  A plurality of cylinders are arranged in a row in a state where both ends of each cylinder are rotatably supported by support means,

  Moreover, since the both ends are supported for each cylinder material by the some support means, a some cylinder material can be arranged in a line in a concentric state more correctly. Therefore, for example, there is no problem that the concentric state is lost because the mandrel is bent due to the weight of the plurality of cylinders, as in the case where a plurality of cylinders are inserted through the cylinders and arranged in a row. Thus, the sheet material can be wound under more uniform winding conditions.

By rotating and driving the support shaft 33 by the motor 41, the plurality of cylindrical materials P arranged in a row can be simultaneously rotated. Of course, not only the support shaft 33 of the support means 3A but also the support shafts of the other support means 3B to 3E may be driven to rotate.

  As shown in FIGS. 1 and 2, the first cutter 5 and the second cutter 6 are provided in the respective support means 3B to 3E, and the sheet material S wound around the outer peripheral surface of the cylindrical material P is provided in each support means 3B. The sheet material S is cut so as not to contact the support frame 31 of ˜3E. The first cutter 5 is provided at a position where the sheet material S is cut at the end E1 on the winding end side of the one cylindrical material P on the winding start side, and the second cutter 6 is provided on the other cylindrical material P on the winding end side.

That is, the lever 51 is swingably provided on the base 313 of each of the support means 3B to 3E, and the first cutter 5 and the second cutter 6 are fixed to the lever 51. By raising and lowering the lever 51, the first cutter 5 and the second cutter 6 can be moved back and forth with respect to the outer peripheral surface of the cylindrical material P, and the sheet material S can be cut at each position when necessary.

  Hereinafter, a sheet material winding method by the sheet material winding apparatus 10 of the present embodiment will be described.

  First, as shown in FIG. 3, the support frames 31 of the support means 3B to 3E are moved forward and backward in order and the chucks 34 are operated to support a plurality of cylindrical materials P and both ends of the cylindrical materials. They are arranged in a line while being rotatably supported by means 3A-3E.

  Next, as shown in FIG. 1, a width W larger than the gap G between the cylindrical materials P is formed on the outer peripheral surface of one cylindrical material P on the winding start side among the plurality of cylindrical materials P arranged in a row. The sheet material S that has it is wound spirally. Here, the sheet material S is wound around the outer peripheral surface of the cylindrical material P by winding a double-sided tape (not shown) together with the sheet material S, but an adhesive layer is previously formed on the outer peripheral surface of the cylindrical material P. The sheet material S may be wound around the adhesive layer. Further, this adhesive layer may be formed by being spirally wound using the sheet material winding device 10 of the present embodiment.

  Then, as shown in FIG. 6, the winding of the sheet material S around the outer peripheral surface of one cylindrical material P on the winding start side is advanced, and as shown in FIG. 7, the side edge on the winding end side of the sheet material S After the portion L1 passes through the end E1 on the winding end side of one cylindrical material P, passes over the gap G, and winds around the end E2 on the winding start side of the other cylindrical material P (reference symbol B in FIG. 7). The sheet material S is started to be cut by the first cutter 5 at the end E1 on the winding end side of one cylindrical material P from the side edge L1 on the winding end side (see reference C in FIG. 7). In addition, what is instruct | indicated by the code | symbol L2 is a side edge part by the side of the winding start of the sheet | seat material S in the figure.

  Then, the winding of the sheet material S is advanced as it is, and as shown in FIG. 8, the side edge L1 on the winding end side of the sheet material S is further changed at the end E2 on the winding start side of the other cylindrical material P. Cutting is started with the two cutters 6 (see symbol D in FIG. 8). In this way, by cutting the side edge L1 on the winding end side of the sheet material S with the first cutter 5 and the second cutter 6, respectively, the cut end T of the sheet material S is separated from the tubular material P as shown in FIG. The sheet material S does not come into contact with the support frame 31 of the support means 3B to 3E in the gap G and the winding operation is not hindered.

  Further, as shown in FIG. 10, if the winding of the sheet material S is advanced while cutting the sheet material S with the first cutter 5 and the second cutter 6, as shown in FIG. Without stopping, the sheet material S can be wound around the outer peripheral surface of the other cylindrical material P on the winding end side. Thus, the sheet material S is continuously wound around the plurality of cylindrical materials P arranged in a row.

  As described above, according to the sheet material winding method and the winding apparatus 10 of the present embodiment, the plurality of cylindrical members P are arranged in a row by the plurality of support units 3A to 3E, and the gap G between the plurality of cylindrical members P is arranged. Since the sheet material S is spirally wound while the sheet material S is cut by the first cutter 5 and the second cutter 6 in the sheet G, the sheet material S is placed on the support frame 31 of each of the support means 3B to 3D in the gap G. The sheet material S can be continuously wound around the plurality of cylindrical materials P arranged in a line without contact. Therefore, compared with the case where the sheet material is wound around the cylinder material one by one, the sheet material can be wound around each cylinder material under more uniform winding conditions. It is possible to reduce the waste of the piece on the end side.

  Moreover, according to the sheet material winding method and the winding apparatus 10 of the present embodiment, as shown in FIG. 7, the sheet material S wound around the outer peripheral surface of one cylindrical material P located on the winding start side is used. After the side edge L1 on the end side winds around the end E2 on the winding start side of the other cylindrical material P located on the end side of winding, the side edge L1 is wound around the one cylindrical material P by the first cutter 5. Since it is made to cut at the end E1 on the end side, when the sheet material S is wound around the outer peripheral surface of another cylindrical material P, the tension of the sheet material S does not fluctuate, and the plurality of cylindrical materials P are covered. Thus, the sheet material S can be wound under more uniform winding conditions.

  Moreover, according to the sheet | seat material winding method and winding device 10 of this embodiment, since the both ends are supported for every cylindrical material P by the support means 3A-3E, a plurality of cylindrical materials P are more It can be arranged in a line exactly in concentric state. Therefore, as in the case where, for example, a plurality of cylinders are inserted into the cylinders and arranged in a row, the mandrel is bent by the weight of the plurality of cylinders, and the concentric state is not impaired. Accordingly, the sheet material S can be wound around the plurality of tubular materials P under more uniform winding conditions.

  Furthermore, in the sheet material winding device 10 of the present embodiment, the support frames 31 of the support means 3B to 3E are provided so as to be movable back and forth in the axial direction of the cylinder material P. The materials P can be arranged in a line quickly and accurately, and the winding work of the sheet material S can be performed efficiently.

  The sheet material winding method and the winding apparatus 10 according to the present embodiment have been described above, but the present invention can also be implemented in other forms.

  For example, in the above embodiment, the first cutter 5 and the second cutter 6 are spaced apart from the gap G in the axial direction of the cylindrical material P as shown in FIG. 8, and the cylindrical material P as shown in FIG. However, the present invention is not limited to this. As shown in FIG. 7, the first cutter 5 has a side edge portion L1 on the winding end side of the sheet material S wound around the outer peripheral surface of one cylindrical material P. After winding around the end E2 on the winding start side, before the side edge L1 comes into contact with the support frame 31 of the support means 3B to 3E in the vicinity of the end E1 on the winding end side of the one cylindrical material P. It suffices if the side edge L1 is provided at a position where the end E1 on the winding end side of one cylindrical material P is cut (see range R5 in FIG. 12). On the other hand, as shown in FIG. 7, the second cutter 6 is another cylindrical material in which the side edge L1 on the winding end side of the sheet material S wound around the outer peripheral surface of one cylindrical material P is located on the winding end side. After winding around the end E2 on the winding start side of P, this side edge L1 contacts the support frame 31 of the supporting means 3B to 3E in the vicinity of the end E2 on the winding start side of the other cylindrical material P. Previously, the side edge L1 may be provided at a position where it is cut at the end E2 on the winding start side of the other cylindrical material P (see range R6 in FIG. 12). Thus, the 1st cutter 5 and the 2nd cutter 6 do not necessarily need to be arrange | positioned in the same position in the circumferential direction of the cylinder material P. FIG.

  Further, each support means may be configured to be detachable from the base 7 like a support means 3F shown in FIG. Thus, according to the number of cylinders P arranged in a row, the number of support means arranged on the base 7 can be appropriately increased or decreased, and it is possible to easily cope with a change in the number of cylinders P. it can.

  Moreover, in the said embodiment, although the sheet | seat material supply means 1 is made to move with respect to the cylinder material P by the moving means 2, in order to move the cylinder material P to the axial direction with respect to the sheet material supply means 1. The support means 3A to 3E may be moved in parallel in the axial direction of the cylindrical material P in synchronization with the axial rotation of the cylindrical material P.

  In addition, the present invention can be carried out in a mode in which various improvements, modifications and variations are added based on the knowledge of those skilled in the art without departing from the spirit of the present invention. In addition, any invention specific matter may be replaced with another technology within the scope of the same action or effect, and the integrally configured invention specific matter is constituted by a plurality of members. Alternatively, the invention specific items configured by a plurality of members may be implemented in an integrated configuration.
