You can have them perform tasks such as:

[Problem to be Solved by the Invention 1] However, in the conventional sorting device, a special winding tape must be prepared and it must be attached to a predetermined position inside the device, which is cumbersome to handle. There was a problem.

In addition, in the conventional device, since the device is placed on the side of the paper ejection table, the elongated tape is oriented perpendicularly to the ejection direction of the ejected paper.

After feeding the length, it is necessary to cut it and place a piece of tape on the discharged paper, and if the discharged paper is, for example, a printed matter, printing work and sorting of printed matter cannot be carried out smoothly. was occurring.

[Object of the Invention] The present invention has been made to solve the above-mentioned problems, and can be used without necessarily attaching a special winding tape, etc. It is an object of the present invention to provide a sorting device that can quickly and reliably supply paper pieces, thereby facilitating the smooth discharge sorting work.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a device in which a piece of paper is inserted between the discharged sheets to separate the discharged sheets. The section has a blade section longer than the long side of the paper strip, and the section is fed by the length of the short side of the paper strip. Moreover, it is characterized in that the cutter is disposed at a position beyond at least one of both sides of the discharged paper.

[Operation] The section of paper fed to the cutter is given a feed shorter than the length of the cutter blade, and then the section is cut into pieces of paper by the cutter. In this classification, the long side of the paper piece can be set to be approximately the same as the length of the cutter blade in the case of R length, and the length of the short side is the same as the feed amount of the paper.

The rotary blade 29 has a cylindrical shape with approximately the same length as the feed roller 24, and has a spiral wooden blade portion 29a on its outer peripheral surface.
The drive shaft 31 of the zero-rotation blade 29 is supported by bearings (not shown) provided on both side plates 12b, 12b of the case 12, and a gear is attached to one end of the drive shaft 31 outside the case 12. 32 and a bevel gear 33 are rotatably mounted.

Further, the bevel gear 33 meshes with a bevel gear 35 attached to the rotating shaft of the motor M provided on the base plate 34 to which the case 12 is attached. Furthermore, gear 32
A gear 26 rotatably supported on the rotation shaft of the feed roller 19 is engaged with the gear 26, and the rotational force of the gear 32 is transmitted to the gear 26. Further, the gear 32 transmits the rotational force to the drive shaft 31 of the rotary blade 29 only when the direction of the rotational force transmitted by the rotation of the motor M is in the direction A in FIG. Sometimes, the rotary blade 29 is
A one-way clutch 42 is attached to drive the rotation. Further, the rotational force transmitted to the gear 26 by the rotation of the motor M is transmitted to the rotation shaft of the feed roller 240 only when the direction of rotation is as shown in FIG. 1, and when the rotation is in the opposite direction, the rotation is A one-way clutch 43 is installed to rotate the feed roller 24 so as not to transmit force to the rotating shaft of the feed roller 24. Therefore, when the one-turn blade 29 is rotationally driven, the rotation of the feed roller 24 is stopped, and conversely, when the feed roller 24 is rotationally driven, the rotation of the rotary blade 29 is stopped. The rotary drive is stopped.

Rotary blade 29 as described above. The rotation of the feed roller 24 is performed by a motor M which is connected to a control means (not shown) and is driven to rotate in forward and reverse directions under the control of the control means in accordance with the discharge operation of the discharged sheets.

The blade 30 is
It is configured to swing slightly upwards around the rear part.

Next, the lower surface of the case 12 is opened, and the section of paper cut by the cutter 28 is configured to fall downward as it is.

Next, the arrangement relationship between the sorting VT device 11 and a machine that discharges discharged sheets (for example, a printing machine that prints and discharges printed matter) will be explained.

In FIG. 1, numeral 36 denotes a printing machine, and the printed matter 37 is discharged from a paper discharge port 38 in the direction of arrow At, and is sequentially stacked on a paper discharge table 39. There is.

The device 11 is divided into a column 4 attached to a base plate 34.
0, and is set at a position that does not block the paper ejection port 38 at the upper part of the paper ejection table 39. Furthermore, in one section, the apparatus 11 is set such that the longitudinal direction of the cutter 28 is substantially perpendicular to the ejection direction of the printed matter 37, and at least one side of both side parts of the cutter 28 is placed on the paper ejection table 39. It is arranged so as to be separated from the printed matter 37 and located outward. That is, one section is cut by the cutter 28 and the section that falls onto the printed matter 37 is a piece of paper 41.
is arranged at a position such that at least one side of both sides thereof protrudes outside the printed matter 37.

Next, the effects of the configurations described above will be explained.

First, the paper 42 is inserted through the second supply port 19 .

In this classification, the paper 42 does not need to be special paper adjusted for work, and when it reaches unnecessary sheets such as so-called waste paper or flyers produced during the printing process, the control means controls the motor M. is driven to rotate in the forward direction, and one section of paper 42 is guided by the guide plate 18, fed into the feed roller 24 and the driven roller 25, and conveyed by a predetermined amount. At this time, the gear 26 for rotationally driving the feed roller 24 is rotated by a gear 32 for transmitting the rotational force of the motor M, and the one-way clutch 42 rotates the gear 32 to rotate the drive shaft 31 of the rotary blade 29. Rotary blade 2
9 never rotates.

Further, the motor M is reversely rotated by a command from the control means to rotate the cutter 2.
8, the section is paper 42, and the elongated tape-like section is paper piece 41.
Cut into. At this time, the rotational force transmitted to the drive shaft by the motor M to rotate the rotary blade 29 of the cutter 28 is transmitted to the gear 26 via the gear 32. Since the feed roller 24 does not rotate, one section of paper 42
is held between the feed roller 24 and the driven roller 25. Also, as soon as cutting is completed, a cam installed on the drive shaft of the single-turn blade turns off the microswitch.
As a result, motor M is immediately stopped.

The paper strips 41 are cut on their long sides by a cutter 28, and the length of their short sides is determined by the feed length when they are fed to the cutter 28. The classification is according to the information and the feed length is g!
By using 4Wi, paper strips can be sent out in tape-like sections of various widths, and the different sections can be easily distinguished based on the difference in the width of the paper strips.

Immediately after the paper piece 41 is cut, it falls directly from the open lower part of the case 12 to the outside of the apparatus, and is deposited on the printed material 37 on the paper output tray 39, at least one of both edges of the printed material. It is placed so that it protrudes from the section.

Since this is done every time and the timing is adjusted to the paper ejecting operation, the sorting of the printed matter 37 can be done efficiently without any delay.

In the embodiment described above, the paper 42 is supplied to the section from the second supply port 19, but the paper 23 is attached to the upper part of the case 12 and is supplied from the first supply port 17 for the roll-shaped section. It's okay.

In addition, in one category, the positional relationship between the device 11 and the discharged paper on the paper discharge table 39 is such that in the first division, the cutter 28 of the mounting Mll is located above the discharged paper, and moreover, the cutter 28 of the mounted Mll is located over the edge of the discharged paper. It only needs to be something that protrudes to the outside, and the vertical relationship and the installation dimensions of the front and back positions do not interfere with the sheet ejecting operation and can be set variously in accordance with the timing of the sheet ejecting operation.

Furthermore, in this embodiment, one motor M is used for the cutter 28.
Although it was configured to drive both the and feed roller 24,
Two motors may be provided and each may be driven separately.

Furthermore, in the above embodiment, the paper is cut into sections according to a signal from the control means indicating that a predetermined number of sheets have been discharged. After cutting one section of paper for insertion, a predetermined amount of sectioned paper is transported, and cutting is performed immediately when a signal is output from the control means indicating that a predetermined number of sheets have been discharged. Also good.

[Effect of the invention] As explained above, one category of the present invention is the device.

A cutter is disposed above the paper output on the paper output tray, and one section has a blade longer than the paper feed length.The first section cuts the paper into paper pieces, and the tape-shaped section cuts the paper into paper pieces, and the cutter cuts the paper pieces at the same time. It is configured such that it can be dropped onto the discharged paper to sort the discharged paper.

Therefore, according to the present invention, it is possible to provide a classification device that does not necessarily require special paper for the work and allows one work to be carried out smoothly.
