Abstract

PROBLEM TO BE SOLVED: To certainly separate a core tape from a core before winding a print. SOLUTION: A core tape 25 having a metal part 25a on its head end is wound around the circumference of a core 24 supported on an axis of rotation 12. When the metal part 25a of the core tape 25 is detected by a detector 16, the axis of rotation 12 rotating in a direction of an axis of rotation L1 stops, and the metal part 25a reaches a separation magnet roller 13. Thereafter, as the axis of rotation 12 is rotated in the reverse direction by a control device 19, the separation magnet roller 13 is rotated, and the core tape 25 is separated from the side of the core 24 from the metal part 25a. Thereafter, the core tape 25 is carried to a taking-up magnet roller 14 by a carrier belt 15 and taken up.

2. Description of the Related Art Conventionally, there has been known a book winding apparatus for winding a large number of printed books arranged in a scissors state around a core while holding the book with a core tape. This book winding device includes a rotating shaft for supporting the core, and a separating magnet roller for separating the core tape wound around the core in advance from the core is provided near the rotating shaft.

[0003] That is, a core tape is wound around a core before the book is wound, and it is necessary to separate the core tape from the core before the winding operation of the book. Conventionally, when separating the core tape, while pulling the core tape wound on the core and contacting the magnet roller to rotate the core, the metal part at the tip of the core tape is attracted to the separating magnetic roller that rotates with it, The core tape is wound around the magnet roller from the leading end of the core tape to separate the core tape from the core.

[0004]

As described above, when the core tape is separated from the core, the tip of the core tape is separated by a separation magnet roller, but the tip of the core tape is adhered to the core tape by an adhesive tape or the like.
When the tip of the core tape is in close contact with the core, the separation roller may not be able to reliably separate the core tape.

If the tip of the adhered core tape is raised, if it is reversed, it will be caught by the guide plate and the brackets around the guide plate, causing a problem of damaging the core tape and the device.

Embodiments of the present invention will be described below with reference to the drawings. 1 to 6 are views showing a printing book winding apparatus according to the present invention and a method of using the same.

As shown in FIG. 1, a pair of the booklet winding devices 10 are disposed on the base 11 on the left and right sides. Can be done

Since the pair of left and right printing book winding apparatuses 10 have exactly the same structure, the right printing book winding apparatus 10 will be described below.

The book winding device 10 includes a rotating shaft 12 provided on a base 11 and supporting a core 24, a detector 16 disposed near the right side of the rotating shaft 12, and a rotating shaft 1.
2 and a separation magnet roller 13 disposed below. The core 2 supported by the rotating shaft 12
Numeral 4 is for winding a large number of printing books 22 (see FIG. 3) which are partially overlapped and arranged continuously in a scissoring shape around the circumference thereof. 25 are wound. In this case, a metal part 25 a made of steel is attached to the tip of the core tape 25, and the metal part 25 a is adhered to another part of the core tape 25.

The detector 16 detects a metal portion 25a of the core tape 25, and a control device 19 is connected to the detector 16. Further, the separation magnet roller 13 rotates by attracting the metal portion 25 a of the core tape 25 to separate the core tape 25 from the core 24.

The core tape 25 separated from the core 24 by the separation magnet roller 13 is conveyed to the take-up magnet roller 14 by the conveyance belt 15 arranged in contact with the separation magnet roller 13 as shown in FIG. Then, it is wound around the winding magnet roller 14. The transport belt 15 is provided with rollers 16a,
16b, 16c, 16d, 16e,
The driving roller is a take-up magnet roller.

As shown in FIG. 2, a plurality of magnets 17 are arranged below the conveyor belt 15 between the rollers 16a and 16d to attract the metal portion 25a of the core tape 25 toward the conveyor belt 15.

The control device 1 connected to the detector 16
9 is also connected to the rotating shaft 12, the separation magnet roller 13 and the take-up magnet roller 14, respectively. Furthermore, between the core 24 on the rotating shaft 12 and the separation magnet roller 13, a book transfer line 21 for transferring a large number of printed books 22 from a not-shown book supply unit to the core 24 on the rotating shaft 12 is provided. Are located.

Next, the operation of the book winding device having the above-described configuration will be described. First, as shown in the right side of FIG.

a is detected by the detector 16. In this case, the normal rotation direction is the same direction as the winding direction of the core tape 25.

A signal from the detector 16 is sent to a control unit 19, and the control unit 19 stops the rotation shaft 12 after a predetermined number of rotations (about ／ rotation). At this time, the metal portion 25a of the core tape 25 is located at the position of the separation magnet roller 13 and comes into contact with the separation magnet roller 13 (see FIGS. 4 and 5).

Next, after winding the core tape 25 around the take-up magnet roller 14, a large number of print books 22 which are partially overlapped and arranged continuously are sent from the print book transport line 21 to below the core 24. At the same time, the core tape 25 is sent from the take-up magnet roller 14 by the conveyor belt 15 in the direction opposite to the above. In this case, since the rotating shaft 12 rotates forward in the direction of the arrow L ₁ , a large number of printing books 22 are wound around the core 24 on the rotating shaft 12 while being pressed by the core tape 25.

As described above, the printing book 22 is obtained by winding the printing book 22 around the core 24 while pressing it with the core tape 25.
