Description

  The present invention relates to a label printer, and in particular, in a label printer that prints on a label printing paper in which a continuous strip of label paper is laminated on a mount (release paper), a half-cut operation that leaves only the mount and cuts only the label paper, or a mount The present invention relates to a label cutting device, a label cutting method, and a label printer that can selectively switch a full cut operation for cutting the entire label printing paper including the label printing paper.

  The label printer is a printer that prints various information such as a barcode, a product name, and a price on the surface of a label having adhesiveness on the back surface. The printed label is affixed to a product or the like according to the purpose of use. The label printing paper is laminated (adhered) on a mount (release paper) so that the label does not adhere when printed by a label printer. As a typical label printing paper, there is one in which labels of a predetermined size are continuously laminated at regular intervals on a strip-like long mount. This label printing paper is usually stored inside the printer as roll paper wound in a roll shape, pulled out from there along a predetermined conveying path via the print head, and printed by the print head. The label printing paper that has been printed on the necessary labels is cut by an auto cutter device or the like and discharged out of the printer.

  On the other hand, since the size of the label differs depending on the purpose of use, if the size of the label to be stacked is determined as described above, different types of label printing paper are required for each label size. As the number of types increases, management of the label printing paper becomes complicated, and the label printing paper must be replaced every time the label size changes during printing. In order to avoid such a problem, there is a label printing paper that is used by laminating strip-like long label papers on a mount and cutting the label papers into a predetermined size before or after printing.

For printers that handle label printing paper in which strip-shaped label paper is laminated on backing paper, a half-cut function that cuts only label paper, leaving the backing paper, and a full-cutting function that cuts both label paper and backing paper (label printing paper) It is desirable to have Patent Document 1 discloses a printer according to the related art having such a half-cut function and a full-cut function. The printer described in Patent Document 1 includes a full cut mechanism 300 and a half cut mechanism 400 inside the printer, and performs half cut or full cut on label printing paper as necessary.

  In the label printing paper cutting method according to another aspect of the present invention, the half-cut position in the step (b) is a position where the cutting support member is separated from the transport path of the label printing paper, and the full-cut position is a half-cut position. It is a position where the cutting support member is moved so as to cross the conveyance path obliquely from the cutting position.

  Another aspect of the present invention is a program for causing a computer to execute each step of the above-described printer control method.

  In the label printer of the present invention, the cutting support member is moved to the third position when half-cutting is performed and the fourth position when full-cutting is performed. And it became possible to perform a full cut. At this time, it is not necessary to change the operation of the movable blade. In addition, since it is a simple mechanism that only moves the cutting support member to the third position and the fourth position, the number of parts is small, and it is possible to reduce the size, weight, and manufacturing cost. Repair and repair are also easy.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing a label printer 10 including a cutting mechanism (cutting mechanism) 20 according to an embodiment of the present invention. Only the part relevant to the present invention is schematically shown. FIG. 2 is a perspective view showing an appearance of the cutter mechanism according to the embodiment of the present invention. The positions of the cutting support member 1 and the movable blade 31 at the time of half cutting are shown.

  The label printer 10 accommodates a label roll paper 50 in which a label print paper 51 is wound inside a casing (frame body) 11, and the label print paper 51 drawn from the label roll paper 50 is guided by a guide (not shown). ) Is conveyed to the outside along a predetermined path (conveyance path 12) guided by the above. A paper detection sensor 13, a print head 14, a platen roller 15, and a paper discharge guide 16 are provided along the conveyance path 12. The cutting mechanism 20 is provided between the print head 14 and the paper discharge guide 16. The cutting mechanism 20 includes a movable blade 31 and a cutting support member 21, and performs a half cut or a full cut of the label printing paper when both cooperate.

  The platen roller 15 is fixed to a drive rotation shaft 17 (hereinafter referred to as “platen shaft 17”), and the platen shaft 17 is rotationally driven in both forward and reverse directions by a conveyance motor (not shown). The platen roller 15 is pressed against the print head 14 by an elastic member (not shown) with the label printing paper 51 sandwiched therebetween. Accordingly, by switching the rotation direction of the platen roller 15, the label printing paper is conveyed in the downstream direction (forward direction) or the upstream direction (reverse direction). Although not shown in FIG. 2, it is possible to provide a transport roller for transporting the label printing paper 51 in addition to the platen roller 15.

  The paper detection sensor 13 provided in the transport path 12 can detect the presence of the label printing paper, and can detect a mark or the like (not shown) attached to the label printing paper 51. Since the distance from the paper detection sensor 13 to the print head 14 is known in advance, the label printing paper 51 or a predetermined mark or the like is detected, and then the predetermined distance of the label is determined by starting printing after moving the predetermined distance. It is possible to print correctly at the position. As the print head 14, a thermal head or an inkjet head can be used. The print head 14 is disposed on the label paper 52 side of the label printing paper 51, and prints various information such as a barcode, a product name, and a price on the label 52 on the surface of the label paper 52.

There are various forms of using a label printer. For example, in the case of barcode labels to be affixed to products displayed at stores, multiple labels printed with the same information such as barcodes and prices are printed, and the same label is affixed to the same type of product one by one . In such a case, a plurality of pieces of information having the same content are continuously printed on the belt-like label paper 52 at predetermined intervals. The predetermined interval is determined by the size of the label. The printed label paper 52 is conveyed to the cutter mechanism 20 and only the label paper 52 is cut (half cut) while leaving the mount 53 in each label unit (between the same printed information). As a result, a plurality of labels 54 cut to a predetermined size are stacked on the mount 51.
(Half cut operation)
The operation of the movable blade 31 and the cutting support member 21 in the case of half cutting will be described with reference to FIGS. 1 and 2.

  The cutting support member 21 has a slanted long and narrow sliding hole 24 into which a sliding shaft 25 is inserted. The sliding shaft 25 is fixed to the casing 11 and supports the cutting support member 21. Therefore, the cutting support member 21 is movable in the oblique direction (from the third position shown in FIGS. 1 and 2 to the arrow B ′ direction) along the sliding hole 24 while being supported by the sliding shaft 25. It is. At the time of half-cutting, the cutting support member 21 is stopped at the half-cut position (third position) shown in FIGS. 1 and 2. The operation of the movable blade 31 is the same for both the half cut and the full cut, and the home blade moves from the stop position (first position) to the cutting position (second position) and stops again. Return to the position (first position) (the second position, which is the cutting position, is the same for both half-cut and full-cut).

  As shown in FIG. 2, the movable blade 31 is rotatably supported by a movable blade rotating shaft 32 fixed to the frame. An elongated hole 33 is provided on the opposite side of the movable blade 31, and a drive pin 35 provided on the drive wheel 34 is inserted therein. The drive wheel 34 is rotationally driven by a drive motor (not shown). When the drive wheel 34 is rotated, the movable blade 31 is rotated in the arrow A-A ′ direction by the drive pin 35.

  When the cutting support member 21 is in the third position shown in FIG. 2 and the movable blade 31 is moved to the second position, the gap between the cutting edge of the movable blade 31 and the cutting base portion 22 of the cutting support member 21 is determined. The second position of the movable blade 31 and the third position of the cutting support member 21 are accurately positioned so that a gap corresponding to the thickness of the mount remains. Accordingly, when the movable blade 31 is driven to the second position when the cutting support member 21 is in the third position, only the label paper 52 of the label printing paper 51 is cut by the movable blade 31, and the mount 53 is not cut. . Therefore, when the cutting support member 21 is in the third position, the movable blade 31 is driven to cut only the label paper 52 (half cut). Thereafter, the movable blade 31 is rotated or reversed as it is to return to the first position. As a result, only the label paper 52 of the label printing paper 51 can be cut at the predetermined cutting position 56. In this state, the label printing paper 51 remains connected by the mount 53, and the cut label 54 is discharged in a state of being stacked on the mount 53. When the predetermined printing is completed, the label printing paper 51 is cut by full cut. Thereby, the printed label paper 55 can be taken out. The label paper 55 that has been fully cut and discharged by the printer is transported to a warehouse, a merchandise display shelf or the like, and the label 54 is peeled off and affixed to the merchandise.

(Full cut operation)
Next, the full cut operation will be described. FIG. 3 is a perspective view showing the positions of the cutting support member 21 and the movable blade 31 when the cutter mechanism 20 according to the embodiment of the present invention is fully cut. The positions of the cutting support member 21 and the movable blade 31 at the time of full cutting are shown. At the time of full cut, the cutting support member 21 is moved to the full cut position (fourth position). A support portion driving member 41 for moving the cutting support member 21 is provided at the rear portion of the cutting support member 21. The support portion drive member 41 includes a lever portion 42 and an action portion 43, and the action portion 43 moves the cutting support member 21 to the fourth position obliquely upward by rotating the lever portion 42 in the clockwise direction. Let The movement of the cutting support member 21 will be described in detail later.

  The fourth position is that when the movable blade 31 is moved to the second position, the movable blade 31 intersects with the fixed blade portion 23 formed by the bottom of the cutting support member 21, and the entire label printing paper 51 is moved. Positioned to cut. Therefore, by driving the movable blade 31 after moving the cutting support member 21 to the fourth position, the entire label printing paper 51 including the mount 53 can be cut as shown in FIG.

(Example of drive mechanism of cutting support member)
FIG. 4 shows a cooperative relationship between the drive mechanism (support drive mechanism) for driving the cutting support member according to the embodiment of the present invention and the cutting support member 21 and the movable blade 31 depending on the position of the cutting support member 21. . The cutting support member 21 can be moved to either the third position or the fourth position by the support portion driving member 41. As described above, the cutting support member 21 is supported by the slide shaft 25 so as to be movable through the long slide hole 24 provided in the oblique direction. Further, the action portion 43 of the support portion drive member 41 is in contact with the bottom surface 26 of the cutting support member 21. Therefore, the action part 43 pushes the cutting support member 21 upward by rotating the lever part 42 clockwise around the drive support shaft 44. The upper surface 27 of the cutting support member 21 is in contact with an obliquely inclined sliding guide surface 47 fixed to the casing (chassis), and the movement of the cutting support member 21 is restricted by the sliding guide surface 47. Therefore, the cutting support member 21 is accurately guided from the third position to the fourth position by the sliding guide surface 47.

  The cutting support member 21 is biased toward the third position by an elastic member 45 such as a coil spring or a leaf spring. Therefore, by turning the lever portion 42 counterclockwise from the position indicated by the broken line to the position indicated by the practice, the cutting support member 21 is moved in the direction of the third position indicated by the solid line by the elastic force of the elastic member 45. Moving. In this manner, the cutting support member 21 moves from the third position B indicated by the solid line (at the time of half cut) to the fourth position B ′ indicated at the broken line (at the time of full cut) according to the rotation of the lever portion 42. It can be moved to either position. On the other hand, the movable member 31 moves from the first position A shown in FIG. 2 to the second position A ′ in both the half cut and the full cut, and returns to the original first position.

  As a drive part which drives the support part drive member 41, an electromagnetic magnet or a motor (both not shown) can be used. When the electromagnetic magnet is used, for example, the lever portion 42 can be biased to one position by an elastic member and biased to the opposite position by the electromagnetic magnet. In the case of using a motor, a method of fixing the support drive member 41 to the drive support shaft 44 and rotating the drive support shaft 44 by a predetermined amount in the forward and reverse directions by the motor is possible.

  In the above-described example, the fixed blade 23 is provided below the cutting table 22 of the cutting support member. Therefore, in the case of full cutting, the cutting support member 21 is slid obliquely upward, It is moved to the position. However, it is also possible to provide a fixed blade at the upper end of the cutting support member of the cutting table 22 and to move it obliquely downward with respect to the movable blade.

(Example of half-cut and full-cut labels)
FIG. 5 shows an example of the label paper 55 that has been half cut and full cut. The label printing paper 51 is conveyed toward the cutting mechanism 20 while being printed by the print head 14. The printed label printing paper 51 is half cut or full cut by the printing mechanism 20. Whether half-cut or full-cut is controlled by a control command from the host device or the like. According to the control command, half cut or full cut is performed at a predetermined position of the label printing paper 51. Assuming that the third position is the home position of the cutting support member 21, half cutting is performed by driving the movable blade 31 when a half cutting command is received. When the full cut command is received, the cutting support member 21 is first moved to the fourth position, and then the movable blade 31 is driven. The operation of the movable blade 31 is the same in both the half cut and the full cut. FIG. 5 shows an example in which two half cuts and one full cut are performed. As a result, the label paper 55 on which the three printed labels 54 are laminated is discharged. The home position of the cutting support member 21 may be the fourth position, and the cutting support member 21 may be moved when a half-cut command is issued.

It is good also as a structure to make it do. In this case, a switch interlocked with the manual lever 79 may be provided so that the movable blade 31 is driven after moving to the fourth position.

  As described above, a motor can be used as the movable blade driving unit 82. The support member drive unit 84 may be configured such that the lever portion 42 is biased to one position by an elastic member and biased to the opposite position by an electromagnetic magnet. It is also possible to fix the support drive member 41 to the drive support shaft 44 and rotate the drive support shaft 44 with a motor.

(Control procedure for cutting operation)
FIG. 7 is a flowchart showing a processing procedure of a cutting operation when the label printing paper 51 is half-cut or full-cut. In this flowchart, it is assumed that the cutting support member 21 is moved to the third position during the non-cutting operation (assuming that the third position is the home position).

  When the cutting means 80 receives the half cut command (S101; YES), the cutting control unit 81 controls the movable blade driving unit 82 to drive the movable blade 31 (S102). As a result, the movable blade 31 and the cutting table 22 cooperate to cut the label paper 51 in half. At the time of half-cutting, since the cutting support member is in the third position (S103; YES), the half-cut processing is finished.

  If the received control command is not a half-cut command (S101; NO), it is confirmed whether it is a full-cut command. If it is not a full cut command (S104; NO), the same confirmation process is repeated (S101, S104). In the case of a full cut command (S104; YES), the cutting support member 21 is moved to the fourth position (S105), and the movable blade 31 is driven after the movement (S102). When the cutting support member 21 is in the fourth position, the movable blade 31 and the fixed blade portion 23 cooperate to cut the entire label printing paper 51 including the mount 53 (full cut). Next, it is confirmed whether or not the cutting support member 21 is in the third position (S103). In the case of full cut, since the cutting support member 21 is in the fourth position (S103; NO), the cutting support member 21 is moved to the third position (S106), and the full cut processing is finished.

  In the flowchart of FIG. 7, the home position of the cutting support member is the third position, but the fourth position can be the home position. In this case, the driving support procedure of the cutting support member during the full-cut processing operation and the half-cut processing operation is reversed, and the cutting support member 21 is moved to the third position during the half-cut, and after the end of the half-cut, Return to position 4.
