Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ink roller device for a printer in a label printing and applying machine.

Labels are generally pre-printed with the store name or label of each vendor, so when printing the price, sales date, etc. using a label printing and pasting machine, avoid printing on the already printed area and place it in the margin. However, since the position of the printing margin differs depending on the label of each store, it is necessary to change the printing position of the price etc. by the label printing and pasting machine even in the case of labels of the same size.

Therefore, when changing a label, the printing device of a label printing and pasting machine is usually adjusted in its front and rear positions so as to match the printing position.

However, the device for applying ink to the rubber stamp of the printing device is supported by the applicator body and is not adjusted according to the adjustment of the printing device, so depending on the adjustment position of the printing device, the ink to be printed and Due to misalignment in relation to the ink vat, it may become impossible to completely apply ink to the stamp.

The present invention includes an ink roller guide on a marking device holding plate that holds a printing device, a primary arm that is pivotally connected to the applicator body, and an engaging member that holds the ink roller at the bottom and engages with the guide at the top. an ink roller device of a link mechanism having a secondary arm having a secondary arm, the engaging member and the retaining plate guide are in abutting engagement with each other in the normal position of the printer, and the ink roller is pressed against the rubber stamp stamp to be printed. By configuring the ink roller so that it is energized so that it is energized, the ink roller always maintains a constant position relative to the marking to be printed, regardless of the adjustment position of the printing device, and the ink roller is energized in the printing process of the printing device. This allows for complete ink application.

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a side view (a side view showing the internal mechanism with one side plate of the main body removed) of a manual label printing and pasting machine equipped with an ink roller device for a printer according to an embodiment of the present invention.

By grasping and manipulating the operating rod 3 that is pivoted to the pivot shaft 2 that is held between the side plates 1 on both sides of the applicator body (front and rear sides in the figure), it is attached to the tip of the swinging rod 4 that is integrated with the operating rod 3. The raised printing device 20 is lowered to print on the label on the printing base plate 5.

Then, by opening the operating rod 3, the swinging rod 4 swings clockwise to return the printing device 20 to its original position (the position shown in the figure), and also moves the feed wheel 7 for the label tape 6 counterclockwise. Turn the label tape 6 to pull it out from the tape roll 8 and remove the label 9 temporarily attached to the top surface of the label tape 6.
is sent out to the lower surface of the labeling roller 10.

The printing device 20 is held between printing device holding plates 21, and screws 22 are passed through the long holes 11 provided at the tip of the swinging rod 4 in the front and back directions with respect to the swinging rod 4 (the left side in the figure is (front) so that the position can be adjusted freely.

An ink roller guide 24 whose upper surface is an arcuate surface 23 is integrally formed on the printing device holding plate 21 and protrudes forward.

30 is an ink roller device, which is the shaft 12 of the pasting roller 10;
a primary arm 31 pivotally connected to the primary arm 3;
A secondary arm 34 is rotatably attached to the upper free end of 1 with a connecting pin 32 and holds an ink roller 33 at the other end, and a guide roller 35 whose rotation axis is the connecting pin 32. , the primary arm 31 and the secondary arm 3
A torsion spring 36 is wound around the connecting pin 32 of No. 4, and the ink roller 33 is constantly connected to the rubber stamp belt of the printing device 20 (in the normal position of the printing device rising as shown in the figure, the stamp 2 to be printed on the lower part of the belt is
5) is energized so as to come into pressure contact with the

A torsion spring 37 is wound around the shaft 12 of the primary arm 31, and a clockwise rotational force is applied to the primary arm 31 to constantly press it against the side surface of the printer 20.

The primary arm 31 is dimensioned so that the guide roller 35 on the upper side of the primary arm 31 comes into contact with the arcuate surface 23 of the printing device holding plate 210 guide 240 during normal operation (when the operating rod 3 is opened in the figure).

The arc surface 23 is an arc centered on the center of the rotation shaft 38 of the ink roller 330 which is in contact with the stamp 25 to be printed.

Since the ink roller device 30 is configured as described above, when the printer 20 is lowered, it presses the ink roller 33,
The ink roller 33 is moved forward while applying ink to the stamp 25, and the connecting pin 32 is also moved forward at the same time.

The engagement between the guide roller 35 and the guide 24 is released by lowering the printer 20 (forward movement of the connecting pin).

When the printing device 20 is further lowered, the ink roller 33 comes into contact with the front side of the printing device 20.

FIG. 2 shows the state at the time when the printer 20 prints on the label on the printing base plate 5. As shown in FIG.

Since the ink roller device 30 according to the present invention is configured as described above, even if the position of the printing device 20 is adjusted and changed with respect to the swinging rod 4 (the elongated hole 11 of the swinging rod 4 allows the printing device 20 to
(shift and fix with screw 22), ink roller device 3
0 guide roller 35 is maintained in engagement with the retaining plate 210 guide 240 circular arc surface 23.

As described above, since the arcuate surface 23 is an arc centered on the center of the ink roller 33 that contacts the rubber stamp 25, the engagement relationship between the ink roller 33 and the stamp 25 is immovable.

Therefore, the conditions for applying ink to the marking 25 by the ink roller 33 during the printing process due to the lowering of the printing device 20 remain unchanged, and regardless of the adjustment position of the printing device 20, the conditions for applying ink to the marking 25 remain unchanged.
The ink is applied to the entire surface.

The printing device 20 in FIG.
FIG. 3 shows the relative position of the ink roller device in a state where it has been shifted integrally to the right side.

The dotted line indicates the position before the printer 20 is shifted (the position shown in FIG. 1).

As described above, if the ink roller device for a printer according to the present invention is used in a label printing and pasting machine, even if the position of the printer is adjusted back and forth according to the label, the ink roller will always be in a constant position with the rubber stamp. This allows for perfect ink application.

In the above embodiment, the printing device guide 24 is provided in front of the printing device, but it may be provided in the rear of the printing device.

Although the primary arm is coaxial with the rotating shaft 12 of the pasting roller 10, it may be supported separately on the main body side plate 1, or it may be mounted on the upper part of the swinging rod 4 at the rear of the printing device 20. .

Although the ink roller device has a link mechanism of two arms, the primary arm 31 and the secondary arm 34, another arm is used between the primary arm and the secondary arm to create a 3-arm link mechanism.
It is also possible to use a link mechanism of individual arms.
