Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a label transfer device in a hand labeler.

In particular, by gripping the grip and hand lever, the wound label continuous body is reliably fed out for a certain length, and the printing device set at a specified position on the machine frame is able to precisely print at the predetermined position on the label. It has been improved so that

Conventionally, this type of label transfer device has the following features: (1) Only the backing paper of a continuous label is held between a pull-out roller and a clamping pressure roller with groove-shaped knurling cut on the outer periphery, and the backing paper is moved by the rotation of the pull-out roller. As I pull it out,
transporting the label while preventing inertial rotation of the pull-out roller by engaging the knurl of the clamping pressure roller with a leaf spring;
By means of a pair of rollers.

(2) A cam that sandwiches the labels, which have been peeled off from the mount of the label continuous body in advance in the previous process in the hand labeler, between a transfer belt suspended between rollers and a bullet plate, and is linked to the gripping operation of the hand lever. There is one that is pivotally attached to the end of the plate and that feeds out the label and cuts the label into one piece by the forward hooking action of the repelling feed claw to the transfer belt, or one that uses a transfer belt and the feed claw. .

However, the conventional means described above suffers from slippage due to uneven engagement between the leaf spring and the knurled surface of the clamping pressure roller, elongation of the label continuous body due to unreasonable tension of the mount, slippage of the feeding pawl, and inertial rotation of the transfer belt. Due to the above reasons, the length of the label being fed out is slightly uneven, but the length of the label is not uniform.

For this reason, there is a convention that optical reading cannot be performed unless printing is done in a precise position on a single label.
CR characters could not be printed satisfactorily with the above-mentioned conventional hand labeler having the label transfer device.

SUMMARY OF THE INVENTION In view of the above-mentioned points, an object of the present invention is to provide a transport device that allows a label to be fed out to have a precisely constant length and to always print at a predetermined position on the label.

A peeling device D is provided for peeling off the label 3 and the mount 4, and a pasting device H is further provided at the front end of the peeling device D for pasting the label 3 onto an object.

The constant pressure mechanism G includes a letterpress launch lever 51.51 that is linked to an actuating part 5B set in the drive mechanism B portion, and the letterpress launch table 50, on which the continuous label body 2 is always placed. Printing is performed on the label 3 by pressing the letterpress surface 51 of the printing device F with the letterpress launcher 50, and the printing pressure applied to the label 3 at this moment is always constant.

Next, the transfer operation in the transfer mechanism A will be explained.

The label continuous body 1 wound into a roll is held in advance on a holding device C, and the tape-shaped label continuous body 2 is fed out from there, and the notches 5 made on the backing paper 4 of the label continuous body 2 are removed by the transport roller. It is locked to the transfer projection 28 of 2L.

To lock the transfer protrusion 28, first rotate the opening/closing lever 46 forward about the fulcrum pin 43, and then move the tip of the continuous label body 2 onto the front peripheral surface of the transfer roller 21. Then, the opening/closing lever 46 is returned to its original position, and the curved surface of the transfer guide 42 that operates together with the opening/closing lever 46 presses the label continuous body 2 against the outer peripheral surface of the transfer roller 2T, and then the hand lever 11 and grip 10 once or twice, the transfer protrusion 2B is engaged with the notch 5 of the label continuous body 2. Next, the hand lever 11 is grasped and released several times to engage the transfer protrusion 2B. , the label continuous body 2 is guided through the guide path 4
9 and over the letterpress launch platform 50, which is a part of the constant pressure mechanism G, to make its tip protrude long toward the front of the machine frame, and then to lock the bottom cover 59 with the machine frame (not shown). Then, the tip of the continuous label body 2 protruding toward the front of the machine frame is rotated clockwise around the fulcrum shaft 60, and the tip of the continuous label body 2, which protrudes toward the front of the machine frame, is reversed approximately 180 degrees rearward in the peeling device D section, and is removed under the transfer port 21. It is guided from the periphery to the outside at the rear of the machine frame along the entrainment prevention member 33.

Next, the bottom cover 59 is rotated back counterclockwise and locked to the machine frame.

Then, when grasping and releasing the hand lever 11 is repeated once or twice, the notch 5 of the mount 4 and the transfer protrusion 2 of the transfer roller 21 are removed.
When 6 and 8 engage with each other, loading of the continuous label body 2 and the mount 4 is completed.

In the peeling device D section, the mount 4 and the label 3 are separated, and the label 3 is made to protrude below the pasting device H.

Then, by tightening the grip 10 and the hand lever 11, the state is displaced from the state shown in FIG. 1 to the state shown in FIG. 2.

Specifically, the hand lever 11 is displaced upward about the fulcrum shaft 12, and the drive lever 22. 2
Move 2 counterclockwise.

A hook 24. which then interlocks with said drive lever 22.22.
24 are displaced in the backward direction, and index pins 30a. It locks with 30a.

In synchronization with this operation, the restraining piece 32a of the stopper 32, which was pressed by the front surface 41 of the hand lever 11 and engaged with the recess 29 of the transfer roller 2T, uses the shaft 35 as a fulcrum by the action of the spring 36. counterclockwise,
That is, it is displaced from the recess 29 in the direction of separation, and the engagement with the recess 29 is released.

On the other hand, in the middle of this tightening, the drive lever 1γ is rotated by counterclockwise rotation of the forked yoke 16.16.
, 11, the swing levers 20, 20 are rotated counterclockwise.

Therefore, the ink soaking roller 56 of the ink supply device E moves in front of the machine while applying ink to the letterpress surface 5T of the printing device F.

Next, when the grip and the hand lever are completely tightened, the constant pressure mechanism G is activated, and its operating portion 58 presses the letterpress launch platform 50 on which the label continuous body 2 is placed and held against the letterpress surface 5T. , a predetermined print is instantaneously applied to the surface of the label 3, and the letterpress launch platform 50 is pushed down to quickly return to the state shown in FIG. 1.

Next, when returning to the transfer mechanism A and releasing the grip 10 and hand lever 11, the state returns from FIG. 2 to the state shown in FIG. 1.

Specifically, the return operation of the hand lever 11 by the action of the drive spring 15.15 causes the hooks 24, 24 associated therewith to be moved forward.

Therefore, the index pin 30 of the next stage is attached to the hooks 24, 24.
Since the index pins 30a and 30a are locked, the index pin 30a is intermittently rotated by one pinch in the counterclockwise direction, that is, in the forward direction, about the main shaft 26 of the transfer roller 2γ.

Thus, by the intermittent rotation of the transfer roller 2γ, the transfer protrusion 28 is transferred a certain distance in the circumferential direction, so that the continuous label body 2, which is locked to the transfer protrusion 28, is accurately fed out for a certain length. is possible.

In addition, in synchronization with this operation, the stopper 32', which had been detached from the recess 29 of the transfer roller 21, is removed from the hand lever 1.
1 returns, the restraining piece 32a that is locked with the next stage recess 29 is brought into close contact with the front surface 41 of the recess 29, thereby locking both of them, thereby preventing inertial rotation of the transfer roller 2T. .

On the other hand, when the grip is released, the ink soaking roller 56 of the printing device E also returns to the state shown in FIG.

Next, other embodiments of the present invention shown in FIGS. 6, 1, and 8 will be described.

On the side surface of the transfer roller 2γ, an indexing member 30 in the shape of a pawl gear, which is pivotally supported by the main shaft 26 and moves together with the transfer roller 2γ, has a plurality of indexing members 30 that are engaged with a locking pin 24a provided at the tip of the hook 24. Indexing claw 30b. It has 30b...

The number of index claws 3 (lb) is provided corresponding to the transfer protrusions 28, 28 provided on the outer peripheral surface of the transfer roller 2T.

The index claw 30b is provided on the outer peripheral surface of the transfer roller 2γ.
, 30b... corresponding recesses 29, 29...
... are provided, and a stopper 32 is provided in the recess 29.
are engaged.

As shown in detail in FIG. 8, the stopper 32 has a tip forming a hook portion 32b' and a base serving as a restraining lever 32b.

The deterrent lever 32b is pivotally supported by a fulcrum pin 54 provided on the stopper mounting member 52 integrally with a hook deterrent lever 53 that engages and disengages from the locking surface 24b of the hook 24 via its upper surface. Due to the action of a spring 55 interposed therein, the fulcrum pin 54 is biased counterclockwise around the fulcrum pin 54 .

That is, this spring 55 places the hook deterrent lever 5 so that the deterrent lever 32b is in the recess 29 of the transfer roller 2γ.
3 are respectively engaged with the engagement surfaces 24b of the hooks 24.

Further, when both levers are locked, the rear surface of the restraining lever 32b is configured to come into pressure contact with the front surface 41 of the hand lever 11.

Note that the stopper mounting member 52 is fixed to the machine frame.

Next, in this operation, the grip 10 and the hand bar 1
1, the state changes from FIG. 6 to the state shown in FIG. γ.

Specifically, the hook 24 interlocked with the hand lever 11 moves backward, and the locking pin 24a locks into the next claw 30b of the indexing claw 30b.

In synchronization with this operation, the deterrent lever 32b, which was in a locked state with the four points 29 by the action of the spring 55, and the hook deterrent lever 53, which was in a locked state with the locking surface 24b of the hook 24. Both are moved clockwise around the fulcrum pin 54 by the upper surface of the hook restraining lever 53 being pressed by the locking surface 24a of the hook 24, which is biased counterclockwise by the elastic force of the spring 25. Rotate as one to release each lock.

Next, by releasing the gripping operation, forward movement is given to the hook 24 which is interlocked with the operation of the returning hand lever 11.

Specifically, as the hook 24 engaged with the next stage claw 30b of the indexing claw 30b moves forward, the transfer roller 2T moves toward the main shaft 26.
The index claw 30b is intermittently rotated by one pitch in the forward direction about the center.

Thus, by this intermittent rotation, ie, the defined circumferential movement of the transfer projection 28 which is locked in the notch 5 of the label continuous body 2, it is possible to reliably convey the label continuous body by a certain length.

Also, in synchronization with this operation, the recess 29 of the transfer roller 2γ
The stopper 32 with the deterrent lever 32b in the detached state is caused by the action of the spring 55 and the hand lever 1.
The transfer roller 21 is locked in the recess 29 of the next stage by pressing the front surface 41 of the transfer roller 21, thereby preventing the transfer roller 21 from rotating due to inertia.

Furthermore, in synchronization with this, the hook restraining lever 53, which had been separated from the locking surface 24b of the hook 24, locks again to the hook 24, and further locks the stopper 32 in the recess 29. Make it certain.

According to the present invention, as described above, by repeating the gripping and releasing of the grip and the hand lever, the transfer roller is moved by one pitch of the indexing member by the engagement and disengagement between the hook and the indexing member linked to the hand lever. Intermittent rotation is possible.

Therefore, it is possible to reliably feed out a constant length of the label continuous body that is locked to the transfer protrusion provided on the transfer roller.

In that case, inertial rotation of the intermittently rotated transfer roller is accurately prevented by engagement between a recess set corresponding to the transfer protrusion and the indexing member and a stopper that engages and disengages with the recess. Therefore, it has the advantage that the transport dimensions of the label continuous body can be made precise.

Therefore, the present invention exhibits optimal effects as a transport device for a hand labeler that prints OCR characters, which is strictly required to print in precise predetermined positions on labels.
