Description

[Detailed description of the invention] This invention relates to a device that continuously cuts off the spines of old books, old magazines, etc. to a minimum in order to effectively utilize paper resources.

Recycling of old books is done by removing the spines from the papermaking process. Conventionally, the back seam is removed by cutting with shearing or removing with a rotating wire brush.
The former has a poor return rate because it also cuts the part of the book that follows the spine, and the latter has the disadvantage that the paper gets stuck in the wire brush. Therefore, this idea is to rotate a carbide milling cutter at high speed and feed the spine of an old book against the cutter with a rotating drum, thereby continuously cutting off the spine to a minimum. For this purpose, the necessary configuration has been adopted.

To explain the configuration based on an example, gates 2 and 2' are built on both sides of the bet 1,
A driving drum 3 is rotatably provided in the lower tier and a driven drum 4 is rotatably provided in the upper tier in two stages, upper and lower, between 2'. For this purpose, the drum shaft is supported on bearing discs 5, 5' installed between the pillars in front and behind each gate 2, 2', and the bearing disc 5' of the driven drum 4 is connected to the beam at the top of each gate 2, 2'. A threaded rod 7 is inserted through the coaxial bearing plate 5' and held by a spring 8. Furthermore, a spring 9 suspended from the beam 6 is installed between the bearing plate 5' and the beam 6.
is provided to prevent the driven drum 4 from springing up. The drive drum 3 is rotated by a deceleration motor 10, and the driven drum 4 is rotated by the meshing of gears 11 and 11' mounted on the drive and driven drum shafts outside the gate 2'. Next, on the side of one gate 2, attach the milling cutter 13 shaft to the case 12 held on one pillar of the gate.
As shown in FIG. 5, the cutter 13 is mounted on a bearing so as to be offset from the center line of the driving and driven drums 3 and 4, and a pulley 14 at the end of the shaft of the milling cutter 13 and a motor 15 are connected by a belt. ing.
Next, a board 16 for feeding books is installed in a stretched manner between the gates 2 and 2' facing the rear side of the driving drum 3 and driven drum 4 in the state shown in FIG.
As shown in FIG. 4, a spring plate 18 with a spring 19 is provided on the partition plate 17 to press the book against the partition plate 17, as shown in FIG.
A drain gutter 20 is installed in a stretched manner between 2'. A horizontal groove 21 shown in FIG. 3 is cut in the circumferential surface of the driving and driven drums 3 and 4 parallel to the rotation axis, and the groove 21 is divided by a vertical groove 22 (shown in FIG. 1). As shown in Figure 1, a knife edge 2 is provided on the peripheral edge of the driven drum 4 on the side of the milling cutter 13.
3 is formed. Therefore, when the spine is cut from the top with the milling cutter 13, the knife edge 23 contributes to the cutting while preventing the book from flying up. The shape of the lateral groove 21 is cut into a scalene triangular shape, and both drums are constructed so that the edge 24 leads in the direction of rotation.

As a result of the above, the book is placed on the partition plate 1 of the feeding device.
7 and is fed in and sandwiched between the upper and lower drums 3 and 4, the edges 24 of the upper and lower drums 3 and 4 adapt to the thickness of the book and engage the book well, securing the book while cutting the milling cutter. Send to 13. If you turn the spine part toward the cutter 13 side when feeding, the spine part will be connected to the upper and lower drums 3, from one end to the other.
The cutting feed is carried out in proportion to the rotation degree of 4. At that time, the vertical groove 22 aims to engage the horizontal groove 21 with the book, eliminating misalignment in different directions that would occur without the vertical groove 22.
The knife edge 23 securely holds the milling cutter 13 during cutting.

This invention uses the vertical and horizontal grooves of the driving and driven drums to hold the books without shifting them in different directions, and cuts them using the knife edge and milling cutter.
It has the effect of resecting the back part with the minimum width.
