Description

[Detailed Description of the Invention] The present invention relates to an ink roller support device for a printing machine used in a hand labeler or the like.

Generally, as shown in Fig. 1, a hand labeler sends a label 2 stuck to a tape 1 onto a stamping table 3 together with the tape 1, and lowers a printing machine 4 onto the top surface of the stamping table in conjunction with a grip lever (not shown). After stamping the price and other information by printing 5, tape 1
By folding and pulling the label 2, the label 2 is peeled off from the tape 1 and sent out.The ink roller support device used for this is a swing frame 7 with an ink roller 6 attached to the tip. is attached with a shaft 8 and is biased by a spring 9 in the direction in which the ink roller 6 is inserted under the printing 5 for stamping, and the printing machine 4 is attached.
Generally, the print 5 comes into contact with the ink roller 6 and is coated with ink as it descends, and as it is further lowered, it is pushed out from under the print along with the swing rod 7, and the ink is applied. For example, as shown in FIG. 2, the roller 6 is attached by attaching a pair of roller support pieces 10a to the tip of the swinging rod 7.
10b, a bearing hole 11a is formed in one side, and a groove 11b is formed in the other side, and a retaining piece 12 made of a plate spring is attached over the open part of the groove 11b, and the retaining piece The ink roller 6 was being attached and detached by pushing out the ink roller 12.

In such a conventional ink roller support device, when attaching or detaching the ink roller 6, it is necessary to pull out the swing frame 7 against a spring in a direction to pull out the ink roller 6 from below the printing machine 4, and then open the retaining piece 12. Since this process was carried out manually by the operator, the workability was extremely poor.

Therefore, the purpose of the present invention is to make it possible to easily attach and detach the ink roller in this type of ink roller support device, and in particular, to enable the detachment to be carried out with a single touch with one hand. The device is equipped with a roller support swing frame whose tip supports an ink roller shaft protruding from both ends of an ink roller that comes into contact with the stamp surface of the printing machine that moves up and down according to the stamping operation of the printing machine. In the ink roller support device for a printing machine, the swinging frame has a first spring and its tip side is biased toward the lower side of the stamping surface of the printing machine, and the swinging frame has a base end that is biased toward the lower side of the stamping surface of the printing machine. It has an inner frame and an outer frame supported by a support shaft, and is biased by a second spring in the direction in which both frames overlap each other, and a pair of springs are attached to the tips of each frame. A recessed part for an ink roller bearing is provided in both supporting parts of one of the two frames, and a recessed part is provided in both roller supporting parts of the other frame. It is provided with an ink roller shaft retaining piece that overlaps the open side and prevents the ink roller shaft inserted into the recessed portion from coming off, and the rotation range of the inner frame in the direction away from the printing machine is limited to the outer frame. The outer frame is forcibly rotated to an angle smaller than the rotation range of the inner frame in the same direction, so that both frames resist the second spring. The present invention relates to an ink roller support device for a printing machine, characterized in that the ink roller support device is configured such that the rollers are separated from each other.

Next, an example in which the present invention is applied to a hand labeler will be explained with reference to FIG. 3 and the subsequent drawings.

In the figure, reference numeral 20 denotes an ink roller support device according to the present invention, which is attached in front of the printing machine 22 that moves up and down on the hand labeler main body 21, and the ink roller 23 is inserted under the printing machine 22, and the printing machine 2
After the ink is applied to the stamping print 24 by the descent of the printing device 2, it is pushed forward by the printing machine.

This ink roller support device has a swinging frame consisting of an inner frame 25 and an outer plate 26. The swinging frame is swingably attached to the hand labeler main body 21 by a shaft 27, and the winding is mounted on the shaft 27. The leading end side is biased toward the lower side of the print 24 by the first spring 28 .

The inner frame 25 and the outer frame 26 are integrally formed with a pair of side walls 25a and 26a, each of which has bent and raised edges. 26 are arranged to overlap each other.

Both frames 25 and 26 are attached to the hand labeler main body 21 by inserting an integral shaft 27 into a bearing hole formed in each side wall 25a and 26a at the base end thereof, and are attached together by the first spring 28 mentioned above. In addition, a second spring 29 wound around the shaft 27 urges both frames 25 and 26 in the direction of overlapping each other.

Also, both frames 25 and 26 have both side walls 25a and 26
A pair of roller support pieces 25b and 26b are integrally molded by extending the tip of the outer frame 2.
The roller support piece 26b of No. 6 has a concave cutout 30 for an ink roller bearing toward the rotation radial direction side.
is formed, and the roller support piece 25b of the inner frame 25 is formed with an ink roller shaft retaining piece 31 that overlaps with the open end side of the recessed notch 30, so that both frames 25 and 26 overlap each other. Concave cutout 3
0 and the retaining piece 31 form a bearing hole for the ink roller.

On the other hand, the base end portion of the inner frame 25 is provided with a rotation angle regulating means. This means consists of an arc-shaped elongated hole 32 centered on the shaft 27 and a stopper shaft 33 inserted through the elongated hole 32 and fixed to the hand labeler main body 21. It is designed so that it can only be rotated.

Note that 25c and 26c in the figure are window holes.

Therefore, the ink roller 23 is attached to both frames 25 and 26.
The shaft portion 2 is placed in the concave notch 30 with the
3a is fitted and is retained and supported by the retaining piece 31, and both frames 2 are moved in accordance with the vertical movement of the printing machine 22.
5 and 26, and the ink roller 23 can be attached and detached by inserting a finger into the window hole 26c and rotating the outer frame 26 against the first spring 28. 25 are both pulled out of the hand labeler main body 21, and the outer frame 26 is further pulled out.
When rotated, the inner frame 25 is moved by the stopper shaft 33.
The rotation of the outer frame 26 is prevented and the outer frame 26 is rotated. As a result, the retaining piece 31 is removed from the position of the concave notch 30, and the ink roller 23 can be taken out from the concave notch 30.

The ink roller support device for a printing machine of the present invention is constructed as described above, and the swinging frame for supporting the ink roller has both inner and outer frames, both of which are biased in the direction of overlapping with each other by a second spring. ,
A pair of roller support pieces are formed at the ends of both frames, and the ink roller is connected to the ink roller bearing recess formed on one roller support piece and the ink roller shaft retaining plate formed on the other side. By supporting the shaft of the ink roller, by rotating the two pieces away from each other, the support for the ink roller shaft is naturally released, and furthermore, the rotation of one side of both frames By providing a rotation angle regulating means for regulating the angle, both frames are automatically separated by forcibly rotating the other frame with one hand against the first and second springs. Therefore, after rotating the entire swinging frame with one hand against the spring that biases the swinging frame to one side as in the conventional case, the ink roller is locked with the other hand. Compared to the release version, the operation for attaching and detaching the ink roller is significantly simplified.
