Abstract

PURPOSE:To provide a fitting and detaching device for a print drum in a stamper wherein an elastic plate with a special shape is fixed to the back side of each print base, and several print bases can be fitted to and detached from a print drum in a single stroke. CONSTITUTION:A U-shaped elastic plate 13 having semicircular arcuate expanded parts at both tip parts is fixed by a screw 14 to the back side of an arcuate print base 12 having a width of about 1/4 of that of the print drum 1. When fitting the print base 12 to the print drum 1, the both tip parts of the plate 13 are forcibly pushed toward a drum shaft 2, whereby the semicircular arcuate parts of the tip parts of the plate 13 are firmly engaged respectively to a corner of a guide rod 4 and a side part of a round stary shaft 5, and simultaneously, a positioning pin 11 is fitted into a hole provided in the print base 12. When detaching the print base 12, the base 12 is simply pulled strongly outward, whereby the arcuate parts of the tip parts of the palte 13 can be drawn off the guide rod 4 and the shaft 5, and the base 12 can be detached.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a device in which a printing drum in a stamping machine can be freely attached and detached and easily replaced.

<Conventional technology> In conventional stamping machines of this type, the printing plate with the desired printing plate attached was firmly fixed to the printing drum using screws, etc. In order to replace the printing plate stand, an operating tool must be used each time, and removal and installation must be carried out separately, which makes the work complicated and time-consuming, and printing efficiency is poor. There was a drawback.

<Problems to be Solved by the Invention> The device according to the present invention is intended to fundamentally improve the above-mentioned conventional drawbacks, and in particular, it is possible to move several printing plates from the printing drum to one-touch operation as needed. It is intended to be easily attached and detached by movement.

Means for Solving the Problems〉 One embodiment of the apparatus according to the present invention will be specifically explained with reference to the drawings. In FIGS. The entire drum is shown, 3 is a disk frame provided on both sides of the printing drum l, 4 is two type holder guide rods, which are attached to the disk frame 3 with screws 9 at a predetermined distance, And 5 is a round shaft of two stays, which are respectively interposed between the guide shafts 4 and are connected to the screws 1.
The printing drum l is fixed to the disc frame 3 by the disc frame 3, the guide rod 4 and the round shaft 5.
It constitutes the frame of. Further, 6 is a boss of the disc frame 3, which is fixed to the disc frame 3 by the screw 7, and at the same time is screwed to the disc frame 3 by the screw 8.
is fixed to the drum shaft 2. Reference numeral 11 denotes a printing plate stand 1, which will be described later, which is protruded from the outer peripheral surface of the disc frame 3 at a predetermined interval.
This is the second positioning pin. Reference numeral 12 denotes an arc-shaped printing plate having a width approximately 1/4 of the circumference of the disc frame 3, and holes or screw holes for attaching the pin 11 and the bullet 13, which will be described later, are bored at predetermined positions. It is set up. This ammunition machine 13 is generally formed into a U-shape as a whole, and the legs at the ends of both sides are bulged in a semicircular arc shape, and the guide rod 4 or the round shaft 5 forming the frame of the drum 1 is formed. It is configured to engage the sides. Reference numeral 14 denotes a screw for fixing the bullet 13 to the back surface of the printing plate stand 12.

In the figure, 15 is a type, 16 is a type holder that can hold and fix this type to the guide rod 4, 17 is a screw that can fix the holder 16 to the guide rod 4, and 18 is double-sided tape on the surface of the printing plate 12. It is a desired printing plate that is attached and fixed via a plate or the like.

<Function> As described above, the device according to the present invention has approximately one part of the printing drum 1.
A U-shaped bullet 13 having semi-circular bulges on both end legs is fixed with screws 14 to the back side of an arc-shaped printing plate 12 with a width of /4, so that this stamp is When attaching the printing plate 12 to the printing drum l, as shown in the figure, by strongly pushing the image leading edge of the bullet 13 toward the drum shaft 2, the semicircular arc-shaped portions of both legs of the bullet 13 are pressed. One corner of the guide rod 4 and the side of the stay round shaft 5 are firmly engaged and locked, and at the same time, the positioning pin 11 is inserted into the hole in the printing plate stand 12, whereby the printing plate stand 12 is attached to the printing drum 1. Easy to install Next, when removing the printing plate 12, simply pull the printing plate 12 outward strongly, and the semicircular arc-shaped parts of both legs of the bullet 13 can be attached to the guide rod 4 and the round shaft. 5 and can be taken out.

<Effects of the Invention> Since the device according to the present invention has the above-described structure, the printing plate table can be easily attached and detached from the printing drum with a one-touch operation, without using a specific tool as in the past. Therefore, it is extremely easy to work, and the printing plate table can be easily replaced, making printing work easier and more efficient.
