[Prior art]

 Conventionally, many types of printing apparatuses of this type have been proposed. The basic structure of the printing apparatus is a label reel on which a label tape is wound and a label tape which is drawn from the reel and travels. On the other hand, it is provided with a printing section for printing characters and symbols, and a tape cutting section for cutting the label tape on which the characters and symbols are printed at a predetermined length.

The printing unit includes a printing head and a platen roller driven by a motor, which are arranged so as to sandwich the label tape from both sides, a feeding reel on which a carbon tape is wound, and a winding driven by a motor. The leading end of the carbon tape pulled out from the pay-out reel is fastened to the take-up reel via a print head, and the driving reel rotates to drive the carbon tape from the pay-out reel. The tape is pulled out and run at a certain speed, and the label tape is pulled out from the label reel by sequentially pulling the tape while sandwiching the label tape between the traveling carbon tape and the driven and rotated platen roller. The label tape is run so that the label on the print section can be The character head is used to print characters and symbols.

On the other hand, the vertical dimension of a label to be manufactured can be easily changed by changing the cutting timing at a tape cutting section. For example, by increasing the cutting timing of a label tape, the vertical dimension of the label can be increased. In addition, the vertical dimension can be changed and adjusted to be shorter by reducing the cutting timing, but the horizontal dimension of the label can be changed by changing the label reel on which the label tape is wound, the print head of the printing unit, and the feeding side of the carbon tape. This is performed by replacing the reel and the take-up reel with those having a desired width.

A brake unit 4 for applying a braking force to the take-up of the tape A is disposed between the feed unit 2 and the brake unit 3, and a character is applied to the label tape A pulled out from the label reel 1 and running. A printing section for printing characters and symbols, 5 is a tape cutting section provided on the lower side of the label tape A running than the feeding section 2, and 6 is a section provided between the feeding section 2 and the tape cutting section 5. Intermittent stop portions for temporarily stopping the travel of the label tape A, 7... Are guide rollers disposed in place to stably run the label tape A, 8. Is The label storage section 9 is disposed on the lower side of the label tape A with respect to the tape cutting section 5, and the label storage section 9 is disposed between the feed section 2 and the printing section 4 to run the label tape A in a running state. It is a disk-shaped rotary cutter for tape cutting that cuts along a direction.

The feed section 2 includes a feed roller 20 driven by a motor (not shown), and press rollers 21 and 21 for pressing the label tape A against the roller 20. When the label tape A is sandwiched between the press roller 20 and the holding rollers 21 and 21, the label tape A is drawn out from the label reel 1 and run as the feed roller 20 is driven and rotated. The holding rollers 21 and 21 are rotatably supported by a support frame 22, and the support frame 22 is attached to a support rod 23 which can swing vertically. By retreating upward, the press rollers 21 and 21 are separated from the feed roller 20 to enable the label tape A to be sandwiched therebetween.

The braking unit 3 includes a brake roller 30 having a given resistance to rotation, a pressing roller 31 capable of being attached or detached or swinging and retracting, and a guide roller 32. When the label tape A pulled out from the label reel 1 is sandwiched between the brake roller 30 and the press roller 31 via the guide roller 32, a constant braking force is applied to the drawer, and the feed is performed. A constant tension is always applied to the label tape A traveling between the section 2 and the braking section 3. The resistance given to the rotation of the brake roller 30 is configured to be arbitrarily adjusted by a dial (not shown).

The printing unit 4 includes a print head 40 that can be moved up and down and a platen roller 41 that is freely rotatable so as to sandwich the label tape A from both sides, and a feeding side where the carbon tape B is wound up. It comprises a reel 42 and a take-up reel 43 for drawing out and winding the carbon tape B from the pay-out reel 42. The take-up reel 43 is operatively connected to a drive pulley 44 driven by a motor (not shown). The carbon tape B on each of the reels 42, 43 is held down by pressing rollers 45, 45 so as not to be loosened. It is configured to press elastically with.

The tape cutting section 5 includes a fixed blade 50 extending in the width direction of the label tape A, and a semicircular movable blade 51 fixed to a rotating shaft 52 extending in the same direction. The blade 51 is driven in synchronization with the stop of the intermittent stop unit 6. Specifically, during the travel of the label tape A, the movable blade 51 is at the retreat position separated from the fixed blade 50, and the movable blade 51 is driven and rotated at the same time when the driving of the intermittent stop unit 6 is stopped. The label tape A is cut between the movable blade 51 and the fixed blade 50.

The intermittent stop unit 6 includes a stop roller 60 and a press roller 61 that are driven and rotated in synchronization with the feed roller 20. The stop roller 60 stores a driving amount when the drive rotation is stopped. An accumulation releasing means (not shown) composed of a spiral spring or the like is provided so that the stop amount is released, that is, the driving amount accumulated with the restart of the driving is instantaneously released and rotated. When the rotation of the stop roller 60 is stopped, the label tape A is slackened just before the stop roller 60, and when the drive is resumed, the label tape A is instantaneously fed by the amount of the slack due to the operation of the accumulation releasing means.

The guide rollers 7 are arranged at appropriate intervals along the travel path of the label tape A, and one ends of the guide rollers 7 are supported by the machine wall. At this time, some guide rollers 7... Can be detachably attached to the machine wall so that the label tape A can be quickly transferred to the guide rollers 7. Also, similar guide rollers 7a are provided on the carbon tape B side.

The label storage unit 8 includes a mounting body 80 having a guide rod 81 extending in the vertical direction, a support 82 supported by the guide rod 81 so as to be able to move up and down, and a label receiver fixed to an upper part of the support 82. The label is stored by successively stacking the labels finished by cutting at the tape cutting section 5 on the receiving plate 83 while lowering the receiving plate 83. .

The rotary cutter 9 is slidably supported on a single horizontal shaft 90 extending in a direction perpendicular to the running direction of the label tape A, and the horizontal shaft 90 swings vertically. The cutter 9 is configured to be able to move up and down and to be appropriately driven by a driving device (not shown). And the tape A can be cut along the running direction, and by moving the horizontal axis 90 upward, the cutter 9 is retracted from the running path of the label tape A, and the cutting is performed. To interrupt. Further, when the cutter 9 enters the path of travel of the label tape A to perform cutting, a receiving base having a slit 92 extending in the same direction as the horizontal axis 90 so that the tape A does not escape from the path. Since the label 91 is provided on the lower surface side of the label tape A, the cutting of the label tape A is performed in a state of being received by the receiving table 91, so that the tape A can be cut stably and reliably. . The cutter 9 is not characterized by a structure in which the cutter 9 can be slidably fixed on the horizontal axis 90 or a structure in which the horizontal axis 90 can swing up and down or can be moved up and down. Is omitted.

Next, the operation of the above configuration will be described. First, prior to the start of use, the press rollers 21 and 21 of the feed unit 2, the press roller 61 of the intermittent stop unit 6 and the press roller 31 of the brake unit 3 are raised and retracted, and at the appropriate position (the label tape A is By removing the guide roller 7 at a meandering position, etc., and retreating the print head 40 of the print unit 4 to form and secure a space that becomes a travel path of the label tape A, the label is kept in this state. The label tape A drawn from the reel 1 is wound around the brake roller 30 via the guide roller 32 of the brake unit 3, and the pressing roller 31 is attached to the roller 30. And presses it down. Further, it passes through the above-mentioned travel path space, and interposes the stop roller 60 of the intermittent stop section 6 by moving down the press roller 61. At the same time, the pressing rollers 21 and 21 are moved downward and pressed against the feed roller 20 of the feed section 2, and the guide roller 7 is mounted in the original position. Thus, the label tape A is set in a meandering manner before and after the feed roller 20.

Next, with the print head 40 of the printing unit 4 raised and retracted, the pay-out reel 42 is mounted on the support unit, and the pressing roller 45 is pressed to prevent the carbon tape B from being loosened. The carbon tape B pulled out from the reel 42 passes between the print head 40 and the platen roller 41 from the guide rollers 7a, 7a, and is fixed to the take-up reel 43 via the guide roller 7a. Then, the setting of the carbon tape B is completed. In addition, since the label tape A runs between the print head 40 and the platen roller 41 as described above, the carbon tape B is substantially between the label tape A and the print head B. I will pass.

In this way, when the feed roller 20 of the feed unit 2 is driven and the label tape A is pulled by the roller 20 and the pressing rollers 21 and 21, the tape A is moved from the label reel 1 to the braking unit 3. The brake roller 30 is pulled out while applying a braking force by the brake roller 30, and travels at a set speed from the brake unit 3 toward the feed unit 2 under a constant tension at all times. On the other hand, when the take-up reel 43 is driven and rotated by the drive pulley 44, the carbon tape B is pulled out from the pay-out reel 42, and the take-up side is rotated via the guide rollers 7a, 7a, the print head 40, and the guide roller 7a. The carbon tape B travels between the print head 40 and the platen roller 41. During this travel, the print head 40 is operated to print on the label tape A. Done. At this time, as described above, the travel of the label tape A is performed only by the feed unit 2 and does not involve the travel of the carbon tape B. Therefore, when the printing operation is not performed, the print head 40 is moved to the label tape A. The carbon tape B can be raised and retracted away from the vehicle, that is, the traveling of the carbon tape B can be interrupted, and wasteful consumption of the carbon tape B can be eliminated.

When the width of a label to be manufactured is changed, for example, when a half width label is manufactured for a general-size label, the print head 40 must have a short width. When the cutter 9 is fixed to the middle position in the width direction of the label tape A by sliding on the horizontal axis 90 while the cutter 9 is being replaced, the cutter 9 is moved downward, whereby the cutter 9 is moved. The label tape A enters the traveling path of the label tape A, and the label tape A is divided into two along the traveling direction. The label tape A is cut by the tape cutting section 5 in the same manner as described above, so that two labels are simultaneously produced. Therefore, work efficiency can be doubled. Further, since there is no need to replace the label tape A or the carbon tape B, it is possible to omit complicated and troublesome work associated with them.

In the above embodiment, the case where one cutter 9 is provided on the horizontal axis 90 has been described. However, the present invention can be carried out in the same manner even if a plurality of cutters 9 are provided. Although it is provided on the upper surface side of the label tape A, it may be provided on the lower surface side. Further, when a plurality of cutters 9 are provided, they may be provided separately on the upper and lower sides.

In addition, although a cutter for rotating a disc is used as the cutter 9, any type of cutter such as a cutter for ultrasonic vibration can be used.

[0026]

[Effect of the invention]

 As described above, according to the present invention, during normal use, that is, when producing a general-size label having a large lateral dimension, the tape cutting cutter is retracted upward from the label tape traveling path. If a label with a smaller lateral dimension than that of the label is to be manufactured, the tape cutter should be inserted into the travel path of the label tape at a position that matches the lateral dimension so that it can be moved along the traveling direction. Tape cutting can be performed, so that the lateral dimensions of the label to be produced by moving the cutter laterally can be changed arbitrarily and very easily and within a short time. It is not necessary to replace the label tape and carbon tape with the change of the horizontal dimension of the above, so the complicated and laborious work accompanying these replacements can be omitted. However, in the case of manufacturing a label with a horizontal dimension that can be divided into 1/2 or 1/3, etc., for a general-purpose label tape, there is a practical effect that the working efficiency at the time of manufacturing can be increased several times. .
