Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a manual labeler in which a transfer tape is intermittently fed each time a hand lever is rotated back and forth, thereby ejecting one label at a time.

With conventional labelers of this type, it was necessary to insert the transfer tape into the narrow space inside the case and attach it to the guide mechanism.
In addition to the inconvenience of having to take time to attach the transfer tape, the structure is complicated and it is difficult to attach the transfer tape because a biasing means such as a spring is used to press the transfer tape against the feed drum. Since it is necessary to move the guide mechanism backward against the spring, there is also the inconvenience that the transfer tape becomes troublesome to attach due to breakage.

The present invention aims to provide a labeler that can eliminate the above-mentioned inconveniences.

The labeler of the present invention includes a case 1, an operating mechanism 2 provided in the case, a tape supply mechanism 3, a printing device 4, and an ink application device 5, which are operated by the operating mechanism 2.
The label peeling mechanism 8 has a label peeling mechanism 8 that folds back the transfer tape 6 sent by the tape supply mechanism 3 and peels off the label 7, and the label 7 peeled from the transfer tape 6 is reliably projected forward by the label peeling mechanism 8. It was constructed in a similar manner.

The center portion 14 of the cover is configured so that it can be opened when the tape 6 is attached, for example, so that it can be easily removed using a knob 141, and the transfer tape 6 is fitted into the receiving portion 111 using the opening formed thereby. At the same time, it is attached to a guide mechanism, which will be described later.

A receiving plate portion 142 is provided in the central portion 14 above the main body, and the bottom surface of the main frame 11 of the case 1 is formed by this receiving plate portion 142.

As shown in FIGS. 1 and 4, the actuating mechanism 2 is always separated from the pushing part 12 of the case 1 by a return means, such as a spring 21, and is rotatably pivoted to the main frame 11. The lever 22 has a first actuating means, e.g. a rack gear 22, provided on its body so as to actuate the tape supply mechanism 3 by the rotational movement of the lever.
1, and a second operating means, for example, a locking protrusion 222, which operates the peeling mechanism 8 by the rotational movement of a lever, and a mounting portion 223 for fixing the printing device 4 at the rotational end. .

The tape supply mechanism 3, as shown in FIGS. 1 and 5,

The inner surface 373 facing the tape 6 is formed into a curved surface so that the tape 6 can slide through this surface.

Furthermore, the guide piece 37 is configured to be able to freely rotate under normal conditions, and therefore is not provided with biasing means such as a spring.

The upper end 371 of this guide piece 37 presses the transfer tape 6 with the label attached, which is engaged with the upper surface of the feed drum 34, and the lower end 372 of the guide piece 37
It presses against the feed drum 34 when it rotates in a direction away from the feed drum 34.

The rotation of the guide piece 37 is caused by the tension of the transfer tape 6 that is generated when the transfer tape 6 in a label-peeled state that is engaged with the lower surface of the feed drum 34 is moved by the feeding operation of the feed drum 34. It can be obtained with

That is, the tension applied to the transfer tape 6 due to the tension of the transfer tape 6 pushes the lower end 312 of the guide piece 37 upward in the figure and rotates the upper end 3γ1 of the guide piece 37 toward the drum.

The suppression piece 38 is the tape 6 after the label 7 has been peeled off.
The tape 6 is pressed against the drum 34 so that the tape 6 is sufficiently locked with the locking protrusion 341 of the drum 34, and is constantly pressed against the drum 34 by the spring 381.

As shown in FIG. 6, the printing device 4 includes an elevating frame 41 that is fixed to the mounting portion 223 of the lever 22 and moves up and down by the rotation of the lever 22, and a printing mechanism provided within this frame. 42.

The printing mechanism 42 has a protrusion 421 as a selector inserted into the body, a selector shaft 422 inserted into a mounting hole 411 provided in the elevating frame 41, and a plurality of A rotating disk 423, a printing belt 424 attached to the rotating disk, and a pedestal 425 provided below the lifting frame 4.1 so as to face the selector shaft 422 and to which the tip of the printing belt 424 is attached.
and an indicator 426 that is combined with the selector shaft 422, and is configured so that the selector shaft 422 rotates a desired rotary disk.

The selector shaft 422 is inserted into the mounting hole 411 and supported so as to be slidable in the axial direction, and is configured to be able to rotate at a desired position.

The rotary disk 423 has a through hole 427 in the center through which the selector shaft 422 is inserted, and grooves 428 of the same number as the number of prints on the printing belt 424 are radially recessed on the inner periphery of the through hole 427. It is.

The rotary disk 423 has its cut groove 428 connected to the selector shaft 42.
The projecting piece 421 of the selector shaft can move in the axial direction of the selector shaft, while the protruding piece 421 of the selector shaft can move in the axial direction of the selector shaft. It engages with the kerf 42B of the rotary disk to rotate the rotary disk.

The indicator 426 is constructed as follows.

First, the indicator 426 is formed so as to be inserted into the positioning hole 412 provided in the lifting frame 41, and
A connecting portion 426' is provided at the end and is connected to the selector shaft 4.
22, and is configured to be interlocked with the axial sliding movement of the selector shaft 422.

Since the connecting portion 426' is formed in an occluded shape to enable rotation of the selector shaft 422, the selector shaft 426'
22, the indicator 426 is not interlocked.

The indicator 426 has an indicating means, for example, an arrow-shaped protrusion formed at a position facing the protrusion 421 of the selector shaft 422, and is configured to confirm the position of the protrusion 421 using this protrusion.

The printing belt 424 is provided with printing marks 43 for stamping on its outer surface sequentially in the longitudinal direction of the belt.
In order to indicate this, readable characters 431 displaying the same characters as the printed characters 43' are provided corresponding to each of the above-mentioned printed characters 43 so that the readable characters 431 appear at the reading position, for example, above.

The printing belt 424 is cut at one point and the terminal 4
24' is bent inward, and this end 424' is inserted into a groove 423' previously provided on the outer circumferential surface of the rotary disk 423, and then the end 424' is inserted into the groove 423' provided in the groove. 429 to be fixed in the groove.

When adopting such a configuration, since the rotation angle of the rotary disk 423 is regulated by the position of the groove 423', the rotation angle of the rotary disk 423 is
It is desirable to configure the structure so that the rotation does not become excessive.

An ink application device 5 is provided opposite to the printing device, and this ink application device 5 is installed on the inner wall of the case 1, for example, on the cover 1.
A rotary rod 52 has one end pivoted on the inner wall of the printer 3 and has an ink roller 51 attached to the other end, and the ink roller is used to constantly connect the ink roller to the printing type of the printing device 4, that is, the printing characters located outside the holder 425. 43', and when the printing device 4 is in the raised position, the ink roller 5 is attached to the printing type 43'.
1 comes into contact and when the printing device 4 descends, the ink roller 51 receives the pressing force of the printing device 4,
This causes the rotating rod 52 to rotate against the spring 53, thereby causing the ink roller 51 to separate from the printing type 43'.

A label 7 is attached to the tape 6 with adhesive,
This tape is wound into a roll and attached to the receiving part 111, and is pulled out from the tip and pressed against the upper surface of the feed drum 34 as shown in FIG. The drum is pressed against the lower surface of the drum, and is then peeled off from the drum by a stripper 39 and sent to the outside.

For this purpose, the tape 6 is provided with a transparent locking hole 61 that locks into the locking protrusion 341 of the drum 34, as shown in FIG.

As shown in FIG. 8, the label peeling mechanism 8 includes a folding section 81 for folding back the tape 6, and a folding section 81 for folding the tape 6 in order to strip the label 7 printed by the printing device 4 from the transfer tape 6.
A second actuating means of the lever 22, that is, a locking protrusion 2 is located on the side of the lever 22.
A sliding piece 82 is arranged to slide when actuated by 22.
and a support piece 83 provided at the tip of this sliding piece 82 to support the rear end of the label 7 that has been peeled off from the tape 6. 8
As shown by the solid line in the diagram, it is retracted, and when the label 7 advances by a predetermined distance, for example, about half, it advances, and then when the label 7 advances completely, it is configured to support the rear part of the label 7 as shown by the dotted line in Figure 8. ing.

Since the labeler of the present invention is as described above, the lever 22
When the printing device 4 approaches the detail 12 direction, the sliding piece 82 retreats and the printing device 4 approaches the transfer tape 6, and as the ink applicator 5 slides the print with its ink roller 51, the printing device 4 depart from the downward path of, and eventually,
A printing device contacts and prints on the label 7 of the transfer tape 6 which is in a stationary state.

Next, when the lever 22 is released and restored by the return spring 21, the rack gear 221 serving as the first actuating means drives the one-way clutch 33 and the drum 34 while keeping them in a connected state, so that the feed drum 34 moves the transfer tape 6 is made to travel a predetermined distance, and on the other hand, the printing device 4 returns to its upward position, and at the same time, the ink applicator 5 also returns to its original state.

Since the transfer tape 6 is folded back at the folding part 81, the label 7 stuck on the tape advances toward the pressing roller 9 due to its hardness, and as the label 7 advances, the sliding piece 82 advances and supports the label 7 as described above.

Since the labeler of the present invention is as described above, when attaching the transfer tape 6, the transfer tape 6 is fitted into the receiving part 111 from the open part of the case 1, and the tape is pulled out and placed on the guide piece 37. It is sufficient to insert it from the lateral direction between the feed drum 34 and the feed drum 34.

In this case, if the guide piece 37 is rotated so that its upper end 371 is separated from the drum 34 as shown by the solid line in FIG. 9, the gap between the guide piece 37 and the drum 34 can be made uniform, so the tape In addition, if the tape is transferred by the feed drum 34 after the tape is inserted, the lower end 372 of the guide piece 37 will automatically rotate as shown by the chain line in FIG. 9 due to the tension applied to the tape 6. As a result, the upper end 371 of the guide piece 37 comes to press the tape 6 against the drum 34, so that the tape clamping operation is automatically performed and the state of tape engagement with the feed drum after this tape clamping operation is changed. There are also profits that can be maintained reliably.
