Description

[Detailed Description of the Invention] The present invention relates to a printing device for printing stickers, etc., which has a simple structure and can economically print beautiful stickers.

Printing stickers, labels, etc. requires a printing process followed by a punching process, so conventionally, the printing plate was attached to a printing plate and printed on a flat pressure printing device with a flat cutting blade device or on a plate roll. A rotary printing device is used, which has a cutter roll wrapped around the plate and embedded with punching blades around the entire circumference, but in flat pressure printing devices, the printing plate is flat, so the lines are smaller than the characters and parts. The print finish of the solid printing part is not clean,
On the other hand, in the case of rotary printing equipment, plate rolls and cutter rolls must be prepared each time according to the size of the printing plate and the size of the product, and cutter rolls are especially expensive, so it is not economical when printing in small quantities. I couldn't make it.

In order to improve these drawbacks, the present invention enables economical rotary printing without changing the plate roll depending on the size of the printing plate, and without using a cutter roll, using a flat cutting blade means. When the base paper is stopped, a plate roll means having a printing plate is rolled along the base paper to perform printing, and a cutting blade means that makes surface contact with the base paper is operated to perform cutting edge processing. The present invention relates to a printing device for printing stickers, etc., which is characterized by the following.

This will be explained below along with examples.

A plurality of printing plates, printing rolls, etc. are prepared according to the number of colors, but Fig. 1 shows an example in which one printing roll means is moved. In the one shown in the figure, a printing plate 2 is wound around the entire circumference of the printing roll 1 within a specified range, with the initial points of reciprocating printing existing on both sides, but the printing plate may be attached to a part of the printing roll, and is configured so that when it is separated from the stencil paper 3, it comes into contact with an ink roll 4 provided at an appropriate position. The pressing means 5 is in the form of a table so that the stencil paper is sandwiched between the pressing means 5 and the plate roll during printing, allowing the stencil paper to slide, but it may also be in the form of a table or roll and moved together with the printing roll. The cutting blade means is flat, and a cutter with a cutting blade embedded in a shape corresponding to the shape of the product is attached to the underside of the cutter table 6 located appropriately above, and when the feed means stops feeding the stencil paper, a link or a cam device 8 having an eccentric shaft 7 as shown in Fig. 2 is operated to lower the stencil paper between the cutting blade means and the opposing pressing means, and the printed stencil paper is cut out to the required thickness, and then the timing of the cutting blade processing is controlled by the above-mentioned link or cam device that moves the cutting blade means to open. The feed means may be an independent motor, etc., but in the one shown in the figure, a lever 11 is oscillated by a crank shaft 9 that is continuously rotated by a motor (not shown) that rotates the printing roll means, etc., and a connecting rod 10 attached to the crank shaft, and the movement of the lever is controlled by a one-way clutch 12.
When the lever is pulled in one direction, the drum rotates to the right in the drawing, and the stencil paper clamped between the pressure rollers 14, 15 is intermittently fed in the same direction in sequence. The feed amount of the stencil paper can be appropriately adjusted by changing the mounting positions of the connecting rod and the lever or crank shaft, or in the case of the one shown in the drawing, the screw-in positions of the nut and the screw rod.

There is a means for separating the base paper and the printing plate on both sides of the printing plate by moving the plate roll means forward while reciprocating and rotating within a predetermined range along the base paper when the transfer of the base paper is stopped. .

There are various configurations of this means, but the one shown in FIG. 1 is such that the plate roll 1 is pulled leftward or rightward by a chain 16, and a gear 17 connected to the shaft of the plate roll is pulled at both left and right ends. The printing plate is engaged with the rack 18 that stands up slightly upward, and printing is performed by bringing the part of the printing plate into contact with the base paper at the middle part of the rack.During this time, the cutting blade means is operated to perform the cutting process. This is how it was done. When the plate roll reaches both ends, the printing plate is separated from the base paper, the cutting blade means is raised, and the feeding means is operated to transport the base paper.

In the device shown in FIG. 3, a printing plate 2 is attached to part or all of the half circumference of a plate roll 1 provided with a step 19, and the plate roll is rotated half a rotation to print alternately starting from both sides of the printing plate. When the base paper is facing the stepped portion, the base paper is transferred.

The present invention is constructed as described above, and since the printing section uses rotary printing, it is possible to print cleanly.Also, since the cutting edge processing is performed using a flat cutting edge, the cutting edge section can be can be made economically,
In addition, printing starting points were provided on both sides of the printing plate, and the base paper to be printed was intermittently fed in the same direction, and when the base paper stopped moving, the printing plate was rotated back and forth to print. It is possible to print at high speed, reduce printing costs, and the apparatus is simple and economical, and can be suitably used for printing stickers, labels, packages, etc.
