Abstract

(57) [Abstract] [Purpose] To provide a take-up spool capable of taking up paper on a take-up shaft without providing pressing plates on both sides of the take-up shaft and preventing winding disorder. [Structure] A tapered winding shaft 1 having a small diameter portion 2 at one end and a large diameter portion 3 at the other end, and a large diameter portion 3 of the winding shaft 1.
And a presser plate 5 provided only on the other end side of the paper, and when the paper 4 is taken up, the paper 4 is drawn up toward the large-diameter portion 3 of the take-up shaft 1, and at this time, the paper 4 is taken up. The right side portion of the sheet was aligned with the holding plate 5 to prevent winding disorder.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a take-up spool for taking up a long object such as paper.

[0002]

[Prior Art]

 Conventionally, take-up spools that take up paper printed by a printer, etc., are provided with presser plates at both ends of a cylindrical take-up shaft, and the opposite sides of these presser plates guide and press both sides of the paper. Thus, the paper is wound around the winding shaft so that the winding is not disturbed.

[0003]

[Problems to be solved by the device]

 However, with such a take-up spool, when removing the wound paper from the take-up shaft, the take-up paper cannot be removed unless at least one holding plate is removed from the take-up shaft. However, there is a problem that paper removal work is troublesome.

This is because the presser plates are provided on both sides of the winding shaft so that winding disorder does not occur.

In view of the above, if the presser plates are not provided on both sides of the take-up shaft, and a long object such as paper can be taken up on the take-up shaft so that the winding is not disturbed, It is not necessary to remove the holding plate from the take-up shaft when removing the taken-up long product from the take-up shaft, and the taken-up long product can be easily removed from the take-up shaft.

An object of the present invention is to provide a presser plate on both sides of the take-up shaft, and to make it possible to take up a long object such as paper on the take-up shaft so as to prevent winding disorder. is there .

[0007]

[Means for Solving the Problems]

 The means of this invention are as follows. (1) A tapered winding shaft having a small diameter portion on one end side and a large diameter portion on the other end side. For example, a long object such as paper is rolled up, and the difference between the small diameter portion on one end side and the large diameter portion on the other end side is small, whereby the whole is formed in a tapered shape with a slight inclination. It should be noted that it is desirable that a locking groove having a substantially square cross section into which the tip of a long object such as paper is inserted is formed on the outer peripheral surface of the winding shaft in parallel with the shaft center. (2) A holding plate provided on the other end side of the large diameter portion of the winding shaft. For example, it is formed in a disc shape, and the side portions of one side of a long object such as paper to be wound are brought into contact with the surface on the winding shaft side so that the side portions of the long object are aligned.

[0008]

[Action]

 The operation of the means of this invention is as follows. When winding a long object such as paper, the long object is drawn so as to be drawn to the large diameter portion on the other end side of the take-up shaft. When the long object is wound on the take-up plate, the side of the presser plate on the side of the holding plate comes into contact with the surface of the presser plate on the side of the take-up shaft. Taken. Therefore, it is possible to wind a long object such as paper on the take-up shaft without disposing the pressing plates on both sides of the take-up shaft and without causing winding disorder.

[0009]

【Example】

 An embodiment will be described below with reference to FIGS. 1 and 2. In these figures, 1 is a winding shaft. The winding shaft 1 is formed with a small diameter portion 2 on the left side and a large diameter portion 3 on the right side, and the difference between the small diameter portion 2 and the large diameter portion 3 is small. ing. On the outer peripheral surface of the winding shaft 1, there is formed a locking groove 5 having a substantially "square" cross-section into which the tip of the paper 4 printed by a printer or the like is inserted. It is formed over the right end face. Therefore, as shown in FIG. 2, the engagement groove 5 is shallow on the small diameter portion 2 side and is gradually formed deeper toward the large diameter portion 3 side. A disc-shaped pressing plate 6 is provided at the end of the winding shaft 1 on the large-diameter portion 3 side. The left surface 6a of the holding plate 6 on the take-up shaft 1 side is in contact with the right side portion of the paper 4 when the paper 4 is taken up by the take-up shaft 1. In addition, at both ends of the winding shaft 1, shaft members 7 and 8 rotatably supported by unillustrated equipment cases and supporting members correspond to the axis of the winding shaft 1 while protruding sideways. Has been established. The shaft member 8 on the side of the holding plate 6 is provided with a gear 9 that is rotated by a drive source (not shown) such as a motor.

With such a take-up spool, when the paper 4 printed by a printer or the like is taken up on the take-up shaft 1, the paper 4 is drawn to the large-diameter portion 3 on the right side of the take-up shaft 1. When the paper 4 is wound up, the paper 4 is wound around the winding shaft 1 while the right side of the paper 4 contacts the left surface 6a of the holding plate 6. As a result, the right side portion of the paper 4 is aligned with the pressing plate 6 so that winding disorder can be prevented. Further, when the paper 4 thus wound is removed from the winding shaft 1, the holding plate 6 is only provided at the end of the winding shaft 1 on the large diameter portion 3 side. Therefore, it is not necessary to remove the holding plate 6 from the winding shaft 1 as in the conventional case, and the paper 4 that has been wound up can be easily removed from the small diameter portion 2 side of the winding shaft 1.

[0011]

[Effect of the device]

 As described above, according to the present invention, since the presser plate is provided only on the other end side of the large diameter portion of the tapered winding shaft having the small diameter portion on one end side and the large diameter portion on the other end side, When winding a long object such as paper, the long object can be wound by pulling it toward the large diameter part on the other end side of the winding shaft. The sides of long objects can be aligned with the holding plate to wind up without disturbing the winding, and since there is no holding plate on both sides of the winding shaft, the holding plate can be wound as in the past. It is not necessary to remove from the take-up shaft, and easily wound long objects can be removed from the take-up shaft.
