Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper material cutting device, and more particularly to a compact paper material cutting device used for cutting a printed material into a predetermined size in a relatively small-sized printing house or company. It is a thing.

[0002]

2. Description of the Related Art A small paper cutting device is used in a relatively small-scale printing place, such as a business card or various tickets, which handles a small amount of printed matter. In addition, incomplete separating lines that are not completely separated may be engraved or perforated, so that a single cutting device is not sufficient in many cases. On the other hand, it is impossible in terms of cost to prepare a plurality of types of devices having different cutters.

Therefore, it is conceivable to replace only the cutter with one cutting device, but heretofore, there has not been proposed a paper material cutting device having a compact and simple structure in which the cutter can be easily replaced.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has a simple structure, the cutter portion can be easily replaced, and the compact structure saves space for installation and is economical. An object of the present invention is to provide a paper material cutting device capable of various kinds of cutting.

[0005]

SUMMARY OF THE INVENTION The present invention comprises a box-shaped main body having an open top surface and a cutter portion which is detachably inserted into the main body from above. The main body is a rotation driving means. The paper material cutting device is characterized in that it has a paper material introduction part and a paper discharge part on its side surface and has a built-in paper cutter, and the cutter part is equipped with a rotary cutter that is rotationally driven by the rotational drive means. Settled.

Preferably, the introduction portions of the main body portion are provided in a plurality of stages, the rotary cutters of the cutter portion are arranged in the same number of stages as the introduction portions, and the plurality of stages of rotary cutters are different from each other. A perforation line is included in the engraving line according to, and a plurality of the cutter parts having different types of rotary cutters are prepared.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of a cutting device according to the present invention, which comprises a box-shaped main body 1 having an open upper surface, and a cutter portion 2 which is detachably inserted into the main body 1 from above.

A motor 3 as a rotary drive means is built in the lower part of the main body 1, and a drive gear 4 is fixed to the output shaft of the motor 3 (FIGS. 3 and 4).

In addition, usually one or two stages of paper material introduction portions 5 and 6 to be cut are formed on one side surface of the main body 1, and the same number of paper materials as the introduction portions 5 and 6 are formed on the opposite side surface. The ejectors 7, 8 are shaped. Paper introduction trays 9 and 10 are provided in the introduction portions 5 and 6, respectively, and the receiving tray 1 is provided in the discharge portions 7 and 8.
1 or a receiving box 12 is provided. Usually, the paper trays 9, 10, the receiving tray 11, and the receiving box 12 are configured to be attachable to and detachable from the main body 1.

The cutter unit 2 includes one or more stages of rotary cutters 13 and 14 which are driven to rotate by a motor 3. The illustrated example has two stages, and the driven gear 15 is fixed to the rotary shaft of the lower rotary cutter 14, and the driven gear 15 meshes with the drive gear 4 to transmit the rotational driving force.

Further, a winding transmission means such as a belt 16 or a chain is wound between the ends of the rotary cutters 13 and 14 on the side opposite to the side where the driven gear 15 is installed.
The rotary power of is transmitted to the rotary cutters 13 and 14 at the same time.

The types of rotary cutter 13 and rotary cutter 14 are different. That is, the rotary cutters 13 and 14 each include a plurality of cutters 17 and cutter receivers 18, but the rotary cutters 13 and 14 have different arrangement intervals of the cutters 17 and cutter receivers 18.

The illustrated rotary cutter 13 is provided with eight cutters 17 and cutter receivers 18. With this arrangement, when the paper shown in FIG. 7 is introduced in the direction of arrow A, eight parallel separating lines are provided. a to h (in this case, an incomplete separating line) are engraved. The rotary cutter 14 has three cutters 17, so the above paper
When introduced in the direction of the arrow, three parallel separating lines i to k are inserted. Thus, for example, eight business cards can be cut out from A4 size printed paper.

As the rotary cutter, not only the one in which the number of the cutters 17 arranged is different, but also the type in which the score lines are different (for example, for complete cut lines, for incomplete cut lines, for perforations, etc.) It is possible to prepare one using a cutter of No. 1 or one for a shredder. Therefore, if a plurality of different types of cutter units 2 are prepared, they can be exchanged and used as needed.

The cutter portion 2 is provided with an upper surface opening 20 of the main body 1.
It is loaded into the main body 1 and docked in the main body 1,
In order to perform this docking easily and reliably, for example, a guide plate 21 extending in the vertical direction is provided on the side surface of the cutter unit 2.
A guide groove 22 is formed on the inner surface of the main body 1 for inserting the guide plate 21 and guiding the guide plate 21 (see FIG. 6). When the cutter part 2 is fitted into the main body 1 of the main body 1, the lower end of the guide plate 21 is aligned with the upper end of the guide groove 22 and lowered as it is, so that the positioning is performed, so that docking can be performed easily and reliably. Is possible.

In order to facilitate the work of loading and unloading the cutter portion 2 into the main body 1, it is preferable to provide a grip portion 23 on the upper surface of the cutter portion 2. The cutter 2 is moved up and down while holding the grip 23 (see FIG. 2). When the cutter unit 2 is docked to the main body 1, the drive gear 4 and the driven gear 1
5 and 5 mesh. Reference numeral 24 is a limit switch that detects that the docking is performed correctly. By detecting that the limit switch is in the proper docking state, the motor 3 can be started.

When the motor 3 is started, the drive gear 4,
The rotary cutters 13 and 14 rotate via the driven gear 15 and the belt 16 to enable predetermined cutting. The paper material to be cut is placed on the paper trays 9 and 10 and fed into the cutter unit 2 from the introduction units 5 and 6. The order is not particularly limited, but usually, the material is first sent to the upper introduction section 5 for primary cutting, and then the primary cut is sent to the lower introduction section 6 for secondary cutting.

FIG. 8 shows an example of cutting different from that shown in FIG. 7. First, 10 perforations m are engraved in a narrow width in the primary cutting, and 5 in the secondary cutting.
By inserting the separation line n of the book, a strip-shaped object connected by perforations m is made. This is a form used, for example, for creating a coupon ticket or the like given to a customer at a supermarket.

When a plurality of types of cutters 2 are prepared, the driven gears 15 are categorized into, for example, business cards and coupon tickets so that they can be easily distinguished.
And / or the grip portion 23 and the like may be color-coded.

[0020]

As described above, the present invention has a simple structure, can easily replace only the cutter portion, has a compact structure, does not take up much space for installation, is economical, and can be used for a wide variety of cutting. There is a possible effect.
