Description

  The present invention relates to a half-cut device that cuts a sheet-like workpiece halfway along its thickness direction and a printer equipped with the half-cut device.

  Patent Document 1 discloses a half-cut device that performs printing on a long medium such as a tube or a tape, and then cuts the long medium halfway in the thickness direction.

  The half-cut device described in Patent Document 1 is provided with a cutter and a stepping motor that sets the amount of movement of the cutter. The operator selects and inputs tube printing or label printing before starting printing. Thereby, the half cut depth of the tube or label after printing is set. Furthermore, the operator can adjust the half-cut depth by inputting the half-cut depth with reference to the cutting state and tube size performed last time. Based on the setting and adjustment, the rotation angle of the stepping motor is controlled to determine the half-cut depth for the tube or tape.

  In the printing apparatus described in Patent Document 2, an uneven cut blade in which unit blades are arranged is used, and a half cut process and a full cut process are performed on the tape after printing. In the half-cut process, perforations are formed on the release paper by moving the cutting blade to the full-cut position and causing each unit blade to bite into the tape. In the full cut process, after the cut blade is moved to the full cut position, the entire tape is cut by moving the cut blade in the width direction of the tape.

  Patent Document 1 and Patent Document 2 disclose techniques related to half-cutting. In order to form a half cut at an appropriate depth on the workpiece, the dimensional accuracy of the cutter has a great influence. For example, if the cutter blade is distorted, even if the relative distance between the cutter and the die is accurately set, the half-cut depth cannot be set appropriately.

  When trying to manufacture a cutter with small variations in dimensional accuracy, each cutter becomes very expensive. On the other hand, a cutter or the like cut from a hoop steel plate is relatively inexpensive, but this type of cutter has a large variation in dimensional accuracy such as blade curvature. If this cutter is mounted on a half-cut device, it becomes difficult to set an appropriate depth because the half-cut is too shallow or too deep. In addition, if the variation in the dimensional accuracy of the cutter is large, the adjustment range becomes very wide when adjusting the relative distance between the cutter and the die for each product, and the adjustment work is complicated.

  The present invention solves the above-mentioned conventional problems, and even if there is a relatively large variation in the dimensional accuracy of the cutter to be mounted, the half-cut device capable of appropriately setting the half-cut depth and the half The object is to provide a printer equipped with a cutting device.

Therefore, the rotation amount of the motor can be automatically set to an appropriate value according to the dimensions of each cutter, and an optimum half-cut depth can be realized.

Partly cutting apparatus of the present invention is further characterized in that information instructing unit for indicating the individual information to be input to the cutter information storage unit is provided in the above structure. For example, in the information instruction unit, the individual information is displayed as a barcode. Alternatively, in the above configuration, the individual information further includes data on a distance between a measurement point set on the cutter blade and a reference line, and a cutter holder is provided to fix the cutter to the movable part. The cutter holder is provided with a pair of restricting portions that contact the die at intervals in a direction along the cutter blade, and the reference line is more than the contact portion between the restricting portion and the die. The cutter holder is pressed toward the die in the middle of a pair of the restricting portions by a pressing drive portion that is set parallel to a position away from the die and driven by the motor .

The moving part can be operated with an optimum driving amount according to the shape of each cutter.

  Moreover, it is preferable that the cutter holder generates an elastic strain in the middle of the pair of restriction portions when pressed by the pressure driving portion.

  When elastic strain is generated in the cutter holder, the distance between the cutter blade fixed to the cutter holder and the die can be corrected according to variations in the dimensions of the blade.

Alternatively, in the above configuration, a work identification unit that detects information of a work to be used is further provided, and the rotation amount calculation unit calculates the rotation amount from both the individual information of the cutter and the work information.

  Furthermore, the present invention may include data obtained by measuring a mounted cutter in advance, and individual information to be input to the cutter information storage unit may be attached to the printer.

  For example, a data sheet in which printer identification data such as a printer manufacturing number and individual information of a cutter mounted on the printer is described is attached. Alternatively, a storage medium such as an IC memory storing the identification data and the individual information is attached.

  Next, the flow from the measurement of individual information of the cutter 17 to the half-cut operation by the half-cut device 10 will be described based on the flowchart shown in FIG.

  The first process P1 shown in FIG. 9 is performed in the assembly and adjustment process of the half-cut device 10 and the printer 1.

  In ST1 (step 1) of the first process P1, the distortion and deformation of the blade 17a of the cutter 17 are measured. FIG. 6 shows the measurement method.

  The cutter 17 used in the half-cut device 10 is cut and processed from a hoop steel material, for example, and the tolerance of the straightness of the blade 17a is large.

  In the measurement direction shown in FIG. 6A, the blade 17 a of the cutter 17 is installed downward on a pair of reference jigs 61, 61 installed on the table 60. A spot S including a part of the blade 17a is photographed by the camera in the vicinity of the center measurement point 17c that bisects the longitudinal dimension of the cutter 17, that is, in the vicinity of the center of the distance between the two reference jigs 61 and 61. As shown in FIG. 6B, this spot S is subjected to image processing, and the vertical distance h from the reference line (reference horizontal line) H to the measurement point 17c at the center of the blade 17a is measured.

  The reference line H is a horizontal line connecting the blade support portions 61 a at the tips of the two reference jigs 61. The reference line H is a straight line on which the original blade 17a should be positioned. When the restricting portions 16a and 16a of the cutter holder 16 abut on the receiving portion 12a of the half-cut die 12, the reference line H is separated from the receiving surface 12a. At a position parallel to the receiving surface 12a.

  In the example shown in FIG. 6, the cutter 17 is distorted so that the blade 17a has a downward projecting shape, and the distance (error: tolerance) h between the reference line H and the measurement point 17c of the blade 17a is positive. . Conversely, when the blade 17a is distorted into a concave shape, the distance h between the reference line H and the measurement point 17c is negative.

  In ST <b> 2 shown in FIG. 9, fixed information including the distance h measured for each cutter 17 is given to the half-cut device 10 incorporating the cutter 17. In the example shown in FIG. 2, an information instruction unit 62 is provided in the half-cut device 10. In the information instruction section 62, the individual information of the cutter 17 including the distance h is indicated by a barcode.

  Alternatively, the printer 1 incorporating the half-cut device 10 may be provided with an information instruction unit 62 such as a barcode instruction.

  The information instruction unit 62 instructs individual information that is dimensional information representing distortion and deformation of the blade 17a of the cutter 17 mounted on each half-cut device 10. The information instruction unit 62 does not have to be a barcode, and may be an IC that stores individual information.

  Further, a data sheet describing individual information of the cutter 17 and printer identification data such as a manufacturing number of the printer 1 on which the cutter 17 is mounted may be attached to the printer 1 or the half-cut device 10 alone. . Alternatively, a storage medium such as an IC memory storing the individual information and the identification data may be attached to the printer 1 or the half-cut device 10 alone. The attachment here means that a data sheet or a storage medium is packed together with the printer 1 or the half-cut device 10 alone.

  In ST3 of the first process P1, after the circuit board including the circuit block shown in FIG. 5 is attached to the printer 1, the display of the information instruction unit 62 is read by a barcode reader or the like, and the distance h Is stored in the cutter information storage unit 44 of the circuit block.

  A second process P2 shown in FIG. 9 shows an operation preparation step immediately after the tape cassette 50 is mounted on the printer 1.

  In ST4, when the tape cassette 50 is loaded in the printer 1, the work information written in the identification unit 55 of the tape cassette 50 is read by the cassette sensor 45 provided in the printer 1 and sent to the work identification unit 46. It is done. The workpiece information sent to the workpiece identification unit includes the widths B1 and B2 of the workpiece W shown in FIG. 4, the thickness t1 of the label tape 52 and the thickness t2 of the adhesive layer 53, and the thickness t3 of the release tape 54, Furthermore, it is the material of the label sheet 52 (data indicating hardness).

  In ST5, the individual information including the distance h recorded in the cutter information storage unit 44 is read to the rotation amount calculation unit 43.

  In ST6, in the rotation amount calculation unit 43, individual information that is dimension information representing distortion and deformation of the blade 17a of the cutter 17 read from the cutter information storage unit 44, and workpiece information identified by the workpiece identification unit 46, Therefore, the optimum pressing driving force F to be applied to the cutter holder 16 in the half-cut device 10 is calculated. Further, the rotation amount (rotation angle) of the half-cut drive motor 36 necessary for obtaining the optimum pressing drive force F is calculated.

  A third process P3 shown in FIG. 9 shows the operations of the printer 1 and the half-cut device 10.

In ST7, when the printing operation of the printer 1 is started, the workpiece W is sandwiched between the platen roller 5 and the print head 4 shown in FIG. The platen roller 5 is driven by the roller motor 6 to feed the workpiece W, and characters, numbers, etc. are printed on the surface of the label tape 52 by the print head 4. In ST8, after the printing is completed, the predetermined portion of the workpiece W is sent out to the half-cut position, that is, the position sandwiched between the half-cut die 12 and the blade 17a of the cutter 17 by the rotational force of the platen roller 5.
In ST9, a half-cut operation is performed by the half-cut device 10.

  In the half cut operation, the drive rotator 32 is rotated by the driving force of the half cut drive motor 36 shown in FIG. 2, and the drive lever 38 is rotated in the α direction by the drive cam 32 b of the drive rotator 32. When the pressing drive portion 38b provided at the front portion of the drive lever 38 rides on the pressure surface 23a of the pressure cam 23, the movable portion 14 is pushed downward with the support shaft 21 as a fulcrum.

  In the ST9 half-cut operation, the rotation amount of the output shaft of the half-cut drive motor 36 is determined based on the rotation amount calculated in ST6. The rotation amount of the output shaft is detected by the rotation amount detection unit 41 shown in FIG. 5 and fed back to the motor drive unit 42. Thereby, the half cut drive motor 36 can be accurately rotated by the rotation amount calculated in ST6.

  As shown in FIGS. 7 and 8, when the movable portion 14 is lowered by the pressing driving force F, the restricting portions 16 a and 16 a of the cutter holder 16 come into contact with the receiving surface 12 a of the half-cut die 12. The workpiece W is located between the relief recess 16b of the half-cut die 12 and the receiving surface 12a of the half-cut die 12, and the workpiece W is halfway through its thickness by the blade 17a exposed to the relief recess 16b. Cut into.

  As shown in FIG. 4, when the workpiece W has the label tape 52, the depth obtained by adding the thickness t1 of the label tape 52 and the thickness t2 of the adhesive layer 53 by the blade 17a in the half-cut operation. Cutting is performed to a position exceeding (t1 + t2), and the cutting depth is set to be less than the total thickness (t1 + t2 + t3) of the workpiece W.

  7 and 8, for the convenience of explanation, the protruding distortion amount and the concave distortion amount of the blade 17a of the cutter 17 are exaggerated.

  FIG. 7 shows an example in which the blade 17a of the cutter 17 is distorted into a downward projecting shape, that is, an example in which the distance h shown in FIG. 6 is positive. In FIG. 7A, the workpiece W2 having the short width dimension B2 is half-cut processed, and in FIG. 7B, the work W1 having the long width dimension B1 is half-cut processing.

  FIG. 8 shows an example in which the blade 17a of the cutter 17 is distorted into a concave shape, that is, an example in which the distance h shown in FIG. 6 is negative. In FIG. 8A, the workpiece W2 having the short width dimension B2 is half-cut processed, and in FIG. 8B, the workpiece W1 having the long width dimension B1 is half-cut processing.

  In ST6 of FIG. 9, the optimum amount of rotation of the half-cut drive motor 36 based on the distance h related to the distortion of the blade 17a obtained from the individual information of the cutter 17 and the width B of the work W obtained from the work information. Is calculated. Based on this calculated value, the drive rotator 32 is driven, and the rotation distance of the drive lever 38 in the α direction is determined. As the rotational distance in the α direction increases, the downward pressing drive force F applied to the pressure cam 23 from the pressing drive unit 38b increases.

  As shown in FIGS. 7 and 8, the pressing driving force F acts between the restricting portion 16 a and the restricting portion 16 a of the cutter holder 16. When the pressing driving force F acts between the two restricting portions 16a and 16a in a state where the two restricting portions 16a and 16a are in contact with the receiving surface 12a of the half-cut die 12, the two restricting portions 16a and 16a In the meantime, a slight downward elastic strain is generated in the metal cutter holder 16. In addition, the cutter holder 16 may generate upward elastic strain depending on the thickness of the workpiece W and the strain direction of the blade 17a.

  By changing the pressing drive force F, the amount of distortion downward of the cutter holder 16 is varied, and the amount of protrusion of the cutter 17 toward the receiving surface 12a of the blade 17a is changed. Thereby, the depth of the half cut with respect to the workpiece W is set appropriately.

  As shown in FIG. 7A, when the workpiece W2 having the short width B2 is half-cut by the blade 17a distorted in a projecting shape, the pressing driving force F is set to be relatively weak. ), When the workpiece W1 having the long width dimension B1 is half-cut, the pressing driving force F is set slightly stronger than that in FIG.

  As shown in FIG. 8, when the blade 17a of the cutter 17 is distorted into a concave shape, the pressing driving force F is set to be stronger than those in FIGS. When half-cutting the workpiece W1 having the long width dimension B1 in FIG. 8B, the pressing driving force F is set to be stronger than that in FIG.

  After the half-cut process is completed, the work is fed forward, and the operation of the full-cut device 8 shown in FIG. 1 completes the printing and the work W after the half-cut process is completed is completely cut to a predetermined length.

  In the half-cut device 10 of the above-described embodiment, the cutter holder 16 that holds the cutter 17 is the movable portion 14, but the half-cut die 12 may be a movable portion that is driven by a half-cut drive motor. Good. In this case, the restricting portions 16a and 16a are formed on the half-cut die 12, a pressing driving force F is applied to the half-cut die 12 between the two restricting portions 16a and 16a, and the half-cut die 12 is elastic. Allow distortion to occur.

  Further, both the cutter holder 16 and the half-cut die 12 may be driven as movable parts.
