In the label generating device that revolves the label substrate in the width direction with a rotary blade, the revolution speed of the label substrate cutting period and the revolution speed of the label substrate conveyance period without changing the revolution cycle of the rotary blade And a label generating device configured to change the ratio of the label base material cutting period and the label base material transport period within the revolution period.

Republished 2013/54668

  In recent years, there are a variety of barrel diameters and barrel outer peripheral shapes of containers (for example, PET (polyethylene terephthalate) bottles) into which cylindrical labels are fitted, and the inner diameter of the opened label is appropriately set accordingly. It is necessary to change to. When the label inner diameter is increased, the width direction dimension or folding diameter of the label base material folded in a sheet shape is increased. Conversely, when the label inner diameter is decreased, the width direction dimension or folding diameter of the label base material is decreased.

  When the width direction dimension of the label base material is changed in this way, in the conventional label generating apparatus as described above, the position of the label base material intermittently conveyed in the vertical direction and the rotary blade revolving in the horizontal direction are arranged. The distance from the revolution center axis was fixed (that is, a constant value). Therefore, when the width direction dimension of the label base material is changed, the approach state (the approach position and the approach angle) of the rotary blade to the label base material cannot be made the same. Although it is possible to replace the rotary blades with different diameters according to the change in the width direction dimension of the label substrate, it is necessary to prepare a number of rotary blades with different diameters. Is complicated.

  An object of the present invention is to enter a state where a rotary blade revolves and cuts across the label base material (entrance position and entry angle) even when the width dimension of the label base material is changed. It is to provide a label generating apparatus and a label manufacturing method that can easily change the label.

  The label producing apparatus according to the present invention includes an upper feed roller pair and a lower feed roller pair that are intermittently conveyed while sandwiching a cylindrical label base material that is folded into a sheet shape to form a long strip, and the upper feed A label generating device comprising: a cutting device that generates individual labels by cutting a label base material at a cutting position between a roller pair and the lower feed roller pair, wherein the cutting device comprises a swivel arm And a disc-shaped rotary blade provided at the end of the swivel arm so as to be able to rotate and rotate, at the peripheral edge of the rotary blade every time the rotating blade revolves one revolution by the rotation of the swivel arm.

It may be configured to change to a predetermined position. The approach position of the rotary blade can be set to a position close to the inside by, for example, about several mm to 10 mm from the end in the width direction of the label base material.

  Thus, when changing the approach position of the rotary blade to the label base material to a predetermined position in the width direction of the label base material, the peripheral edge of the rotary blade that revolves is, for example, several mm to the width direction end of the label base material. If it sets so that it may contact a label base material first in the position which approached about 10 mm inside, the cutting | disconnection edge part of a label will be formed in the beautiful state (for example, linear form). Moreover, it is preferable to set the approach angle of the rotary blade with respect to the label substrate to about 15 to 45 degrees, more preferably about 15 to 30 degrees.

  In this case, it is preferable that the rotation speed of the rotary blade is set to 3 to 7 times the revolution speed of the rotary blade.

  Further, in the label generating apparatus according to the present invention, the rotary blade approaching state changing means is constituted by a moving mechanism that moves the position of the moving frame that supports the cutting device including the swivel arm and the rotating blade with respect to the fixed frame. Alternatively, it may be configured by a changing mechanism that changes the arm length from the rotation center axis of the turning arm to the rotation center position of the rotary blade.

  Furthermore, the label production | generation apparatus which concerns on this invention WHEREIN: The clamp apparatus which clamps a label base material in the vicinity position of the up-and-down both sides of the said cutting position may be provided. A voice coil motor can be used as the actuator of this clamping device.

  When a voice coil motor is used as the actuator of this clamping device, it is possible to clamp and release the label substrate in a short time with a sufficient clamping force, and it is possible to sufficiently cope with a high label production speed.

  According to another aspect of the present invention, there is provided a label manufacturing method in which a cylindrical label base material that is folded into a sheet shape to form a long strip is conveyed to a cutting position by a predetermined length, and a disk-shaped rotary blade that rotates is 1 A label manufacturing method for manufacturing individual labels by cutting a label substrate every time it rotates and revolves, and a peripheral edge of a rotary blade that revolves while rotating is predetermined from an end in a width direction of the label substrate. It enters and cuts the label base material at a predetermined position close to the inside by the length.

  In the label manufacturing method according to the present invention, the predetermined dimension is preferably about several mm to 10 mm.

  Moreover, in the label manufacturing method which concerns on this invention, it is preferable that the rotation direction of the said rotary blade is a direction opposite to the revolution direction of the said rotary blade.

Can be changed. Therefore, it is possible to easily and quickly adjust the label base material having different width direction dimensions. Moreover, the versatility of a label production | generation apparatus improves because the width direction dimension range of the label base material which can be applied spreads.

  In addition, according to the label manufacturing method of the present invention, even when the label base is made of a thin and soft film material, the label can be cut cleanly without disturbing the cut end of the label.

  Embodiments according to the present invention will be described below in detail with reference to the accompanying drawings. In this description, specific shapes, materials, numerical values, directions, and the like are examples for facilitating the understanding of the present invention, and can be appropriately changed according to the application, purpose, specification, and the like. In addition, when a plurality of embodiments and modifications are included in the following, it is assumed from the beginning that these characteristic portions are used in appropriate combinations.

<First Embodiment>
FIG. 1 is a right side view of a label generating apparatus 10 according to the first embodiment of the present invention. FIG. 2 is a diagram illustrating a first feed roller pair, a second feed roller pair, and a third feed roller pair included in the label generating apparatus 10.

  The label generation device 10 generates individual labels L by cutting a cylindrical label base material LS which is folded into a sheet shape and forms a long band shape by a predetermined length. The individual labels L generated by the label generating device 10 are supplied to a label mounting device (not shown), and are fitted around a container such as a PET bottle in an opened state.

  The label substrate LS fed out from a label substrate supply device (not shown) is wound around the surface of the support member 2 by about 1/4 turn, so that the transport direction is, for example, from the horizontal direction to the vertically downward direction (arrow α direction). And is supplied to the label generating apparatus 10.

  As shown in FIGS. 1 and 2, the label generating apparatus 10 includes a first feed roller pair 12, a second feed roller pair 14, and a third feed roller pair 16 in order from the top along the conveyance direction of the label base material LS. Is provided. Each pair of feed rollers 12, 14, and 16 includes drive rollers 12a, 14a, and 16a and driven rollers 12b, 14b, and 16b provided in contact with each other. Motors 13, 15, and 17 are connected to the drive rollers 12a, 14a, and 16a of the feed roller pairs 12, 14, and 16, respectively. As a result, the drive rollers 12a, 14a, 16a of the feed roller pairs 12, 14, 16 are intermittently rotationally driven by the motors 13, 15, 17, so that the label base material LS is fed to the feed roller pairs 12, It is configured to be intermittently conveyed by a predetermined length while being sandwiched between 14 and 16. The second feed roller pair 14 and the third feed roller pair 16 correspond to the “upper feed roller pair” and the “lower feed roller pair” in the present invention.

  A mark sensor 18 is disposed between the first feed roller pair 12 and the second feed roller pair 14. The mark sensor 18 is for detecting the reference mark M printed in each label L on the label substrate LS between the first feed roller pair 12 and the second feed roller pair 14. The mark sensor 18 optically detects the presence or absence of the reference mark M, for example, and a reflective type or a transmissive type is used. The detection result of the mark sensor 18 is output to a control unit described later.

  As shown in FIG. 2, the label base material LS has a continuous belt shape in which a cylindrical label L attached to a container is continuously connected and is folded into a sheet shape. The label base material LS (namely, label L) is formed of, for example, a highly stretchable resin film having an elastic deformation rate of about 40 to 50%. Alternatively, the label substrate LS may be formed of a heat-shrinkable resin film. Each label L included in the label base material LS is printed with the product name and design of the container in which the label L is to be fitted, and the reference mark M. The label base material LS is generated into individual labels L having a predetermined length by being cut at a cut position C located in the middle of the transparent portion adjacent to the reference mark M.

  Referring again to FIG. 1, the label generating device 10 further includes a cutting device 20. The cutting device 20 is for cutting individual labels L from the label base material LS at the label base material cutting position K between the second feed roller pair 14 and the third feed roller pair 16. The cutting device 20 in the present embodiment is configured to revolve the rotating disc-shaped rotary blade 22 around the rotation center axis O in a substantially horizontal direction. Accordingly, the rotary blade 22 moves so as to cross the label base material LS at the label base material cutting position K for each revolution, and as a result, the individual labels L are cut and formed from the label base material LS. Details of the cutting device 20 will be described later.

  In addition, a label conveying device 90 is provided below the label generating device 10. The label transporting device 90 sequentially transports the label L generated by the label generating device 10 to the label delivery position β located vertically below. The label conveying device 90 is stretched over a guide roller 91 provided in the vicinity of the third feed roller pair 16 and in the label delivery position β, a pulley 92 rotated in the direction of the arrow by driving a feed motor (not shown), and the pulley 92. Two feed belts 93 (only one is shown), a suction mechanism portion 94 for sucking and holding the label L on the feed belt 93, and a suction mechanism by sequentially bringing the label L into close contact with the feed belt 93 from its lower end to its upper end. The suction assisting portion 95 assists the suction holding operation of the label L to the feed belt 93 by the portion 94.

  The feed belt 93 is given a constant tension by the tension roller 96 and circulates between the vicinity of the third feed roller pair 16 and the label delivery position β. The feed belts 93 are arranged in parallel with each other along the vertical direction at intervals narrower than the width of the label L to be conveyed. Each feed belt 93 has a plurality of suction holes formed at regular intervals along the longitudinal direction at the center in the width direction.

  The suction mechanism unit 94 includes suction chambers 94a and 94b disposed along the feed belts 93 between the guide rollers 91 and 91, respectively. A suction device such as a compressor is connected to the suction chambers 94 a and 94 b through a connection port 97. As a result, a suction force acts on the suction hole of the feed belt 93 through the suction port opened in the contact surface of the suction chambers 94a and 94b with the feed belt 93.

  The suction assisting portion 95 is provided so as to face each feed belt 93 across the conveyance path of the label L, and includes a pair of pressing rollers 98, two guide rollers 99a and 99b, and a motor (not shown). The belt 101 is stretched over a pulley 100 that is rotated by driving the belt 101, and a tension applying mechanism 102 for applying tension to the belt 101. The belt 101 driven by the pulley 100 rotating in the arrow direction is set so as to circulate at the same speed as the moving speed of the feed belt 93. The pressing roller 98 presses the label L toward the feed belt 93 via the belt 101 in order to bring the label L fed from the third feeding roller pair 16 into close contact with the feed belt 93.

  A label delivery device 110 is installed below the label conveying device 90. The label delivery device 110 receives the label L transported to the label delivery position β by the label transport device 90 and delivers it to a label mounting device (not shown). The label delivery device 110 includes a plurality of take-up members 112 that hold the label L by suction. The take-up member 112 passes through the label delivery position β by rotating by a drive mechanism (not shown). At this time, the label L is delivered from the label conveying device 90 to the take-up member 112. Thereafter, the label L is conveyed to the label mounting apparatus while being sucked and held by the take-up member 112.

  Next, the cutting device 20 of the label generation device 10 of this embodiment will be described. FIG. 3 is a view of the label generation apparatus 10 as viewed from above, and FIG. 4 is a view of the label generation apparatus 10 as viewed from the right side (excluding a fixed frame). 5 is a view of the label generating apparatus 10 as viewed from the front side, and FIG. 6 is a view of the right side as viewed from the line ZZ in FIG.

  The cutting device 20 includes a label base material cutting unit 24 that cuts the label base material LS in the horizontal direction by the rotary blade 22 and a label that intermittently conveys each cut position C of the label base material LS to the label base material cutting position K. And a base material transport unit 26. Here, the label base material transport unit 26 includes the second feed roller pair 14 and the third feed roller pair 16 described above (see FIGS. 1 and 2).

  The label base material cutting part 24 has a rotary blade 22 that revolves while rotating on a circumference of a predetermined radius R from a rotation center axis O in the vertical direction. The rotary blade 22 intersects with the label base material LS when moving within a predetermined range of the revolution trajectory (a range sandwiched between the direction of the position S and the direction of the position E in FIG. 3), and moves the label base material LS in the width direction. Or cut horizontally. Therefore, as shown in FIG. 4, the label base material cutting position K is provided at a height position on a plane where the rotary blade 22 of the label base material cutting portion 24 revolves.

  The rotary blade 22 is rotatably attached to one end of a plate-like swivel arm 30 that is fixed to an intermediate position of a support shaft 28 that is rotatably arranged on the base board 27. The radius of the rotary blade 22 is about 3/5 of the revolution radius R. The rotary blade 22 is fixed to the lower end of a rotary shaft 32 that is rotatably attached to the turning arm 30. A dummy blade 22d is attached at a position symmetrical to the rotary blade 22 at the other end of the swivel arm 30. The dummy blade 22d functions as a balancer for suppressing swinging in the revolving operation of the rotary blade 22.

  A pulley 36 for transmitting the rotational force of the revolving motor 34 of the rotary blade 22 is fixed to the lower end of the support shaft 28. The motor 34 is disposed at a predetermined position closer to the back side than the support shaft 28 of the base board 27. A timing belt 38 is bridged between the rotor 34 a of the motor 34 and the pulley 36. The motor 34 is a servo motor whose speed is controlled by a servo mechanism.

  When the label generating apparatus 10 is operated, the motor 34 rotates counterclockwise at a predetermined speed, and the rotational force of the motor 34 is transmitted to the support shaft 28 by the timing belt 38 as shown in FIG. 28 rotates counterclockwise. As shown in FIG. 3, the turning arm 30 is rotated counterclockwise (in the direction of the arrow r <b> 1) by the rotation of the support shaft 28. Thereby, the rotary blade 22 attached to the tip of the swivel arm 30 revolves counterclockwise (in the direction of the arrow r4) on the circular orbit having the radius R from the support shaft 28. In FIG. 3, the revolution circular orbit position T of the peripheral edge 22a of the revolving rotary blade 22 is indicated by a two-dot chain line.

  On the upper side of the turning arm 30 of the support shaft 28, a motor 40 for rotating the rotary blade 22 is provided. A rotational force relay member 42 for relaying the rotational force of the motor 40 to the rotary blade 22 is rotatably provided on the support shaft 28. The motor 40 is disposed at a predetermined position closer to the left side than the support shaft 28 of the moving frame 44 made of a plate material. The base end portion 45 of the moving frame 44 is attached to the fixed frame 21 of the label generating apparatus 10 with, for example, a bolt. The moving frame 44 that supports the label base material cutting unit 24 including the rotary blade 22 can be moved forward and backward with respect to the label base material LS by a moving mechanism described later.

  A belt 46 is stretched between the rotor 41 of the motor 40 and the upper portion of the rotational force relay member 42. On the other hand, a belt 48 is stretched between the lower part of the rotational force relay member 42 and the upper part of the rotary shaft 32 that supports the rotary blade 22. The motor 40 is a servo motor whose speed is controlled by a servo mechanism.

  When the label generating apparatus 10 is operated, the motor 40 rotates clockwise (in the direction of the arrow r2) at a predetermined speed in FIG. The rotational force of the motor 40 is transmitted to the rotational force relay member 42 by the belt 46 and further transmitted to the rotational shaft 32 by the belt 48. Thereby, the rotating shaft 32 rotates clockwise, and the rotary blade 22 fixed to the lower end of the rotating shaft 32 rotates clockwise (arrow r3 direction).

  In the label base material cutting part 24 of the cutting device 20, the base board 27, the intermediate part of the support shaft 28, the turning arm 30 attached to this intermediate part, and the rotational force relay member 42 are as shown in FIG. The side is covered with a cover member 50 having a side wall 50a. The side wall part 50a is fixed to the base end part 45 and the front end part 47 of the moving frame 44 by, for example, bolts or the like. Therefore, the cover member 50 can move integrally with the moving frame 44.

  The side wall 50 a of the cover member 50 is formed in a shape and size that do not interfere with the revolution circular orbit position T of the rotary blade 22. In the present embodiment, the side wall 50a has a substantially octagonal shape when viewed from above. However, it is not limited to this, The side wall part 50a may be formed in other shapes, such as cylindrical shape, for example.

  Moreover, the side wall part 50a of the cover member 50 has the opening part 52 which opposes the label base-material conveyance part 26 side. The revolving rotary blade 22 cuts the label base material LS at the label base material cutting position K when revolving and moving the position exposed to the outside from the opening 52 of the side wall 50a.

  Furthermore, the cover member 50 has an upper wall portion 50b and a lower wall portion 50c that cover the upper and lower portions of the revolution region (excluding the outside of the opening portion 52) of the rotary blade 22 that revolves by the revolving arm 30. On the upper side of the upper wall part 50b, a motor 40 for rotation protrudes and is installed, and on the lower side of the lower wall part, a motor 34 for revolution, a pulley 36, and the like are arranged. As described above, the rotating blade 22 that revolves is covered by the cover member 50 except for the label base material cutting position K, so that the safety of the label generating apparatus 10 for the operator is improved.

  As shown in FIG. 5, the label base material cutting position K is located at the center of the interval between the second feed roller pair 14 and the third feed roller pair 16. A protective member 54 is provided between the second feed roller pair 14 and the third feed roller pair 16 to guide and protect the rotary blade 22 when the rotary blade 22 cuts the label base LS. It is installed. As shown in FIG. 6, a groove 55 into which the rotary blade 22 is fitted is provided on the side surface of the protective member 54 that faces the rotary blade 22.

  The third feed roller pair 16 applies a constant tension to the label base material LS in cooperation with the second feed roller pair 14 while the rotary blade 22 cuts the label base material LS. When the label L is cut off, the label L is transported downstream. The first feed roller pair 12 and the second feed roller pair 14 start transporting the label base material LS with a slight delay after the third feed roller pair 16 starts transporting the label L. When the leading end is nipped by the third feed roller pair 16, the function of conveying the next cut position C of the label base material LS to the label base material cutting position K in cooperation with the third feed roller pair 16 is achieved.

  Referring to FIG. 3 again, the cutting device 20 changes the rotary blade 22 so that the rotary blade 22 enters the same entry state with respect to the label base material LS even when the width direction dimension W of the label base material LS is changed. An entry state changing means is further provided. In this embodiment, the rotary blade approach state changing means changes the approach state of the rotary blade 22 to the label base material LS by changing the revolution circular orbit position T of the peripheral edge of the rotary blade 22 relative to the label base material LS. The More specifically, the rotating blade approaching state changing means is configured such that the peripheral edge portion of the rotating blade 22 is the same as that of the label base material LS at a predetermined position inward from the widthwise end of the label base material LS in the rotating blade approaching state. The moving mechanism 60 that moves the position of the moving frame 44 that supports the label base material cutting unit 24 of the cutting device 20 including the swivel arm 30 and the rotary blade 22 with respect to the fixed frame 21. Consists of.

  The moving mechanism 60 includes a slide guide 45 a arranged along the fixed frame 21 of the label generating apparatus 10. The slide guide 45a is fixed to the base end portion of the moving frame 44 by, for example, a bolt. The slide guide 45 a has a guide portion 45 c that slidably engages with a guide rail 23 provided on the fixed frame 21. Accordingly, the moving frame 44 is provided so as to be slidable in the arrow X direction along the fixed frame 21.

  The rotation center axis O of the support shaft 28 rotatably supported by the moving frame 44 faces the center in the width direction of the label substrate LS. Thus, when the moving frame 44 moves forward and backward with respect to the label base material LS, the rotation center axis O of the support shaft 28 that is the revolution center of the rotary blade 22 supported by the moving frame 44 is the center in the width direction of the label base material LS. Move on a perpendicular line through As a result, the revolution circular orbit position T of the rotary blade 22 with respect to the label base LS is changed in a direction perpendicular to the surface of the label base LS. In the present embodiment, since the label base material LS is intermittently conveyed along the vertical direction, the revolution circular orbit position T of the rotary blade 22 is changed in the horizontal direction. The moving frame 44 is adjusted in position by a screw feed mechanism, which will be described later, and then fixed in an immobile state by a fixing handle (not shown).

  A female screw hole 45b is formed in the end surface of the slide guide 45a, and one end of a feed screw 64 is screwed into the female screw hole 45b. The feed screw 64 is rotatably supported in a penetrating state by a screw support member 66 erected on the fixed frame 21. A pulley 68 is attached to the other end of the feed screw 64. A shaft support member 70 is disposed adjacent to the side of the pulley 68. The shaft support member 70 is erected on the fixed frame 21. The shaft support member 70 rotatably supports the shaft 71 in a penetrating state. A pulley 72 is attached to one end of the shaft 71, and a timing belt 74 is wound around the pulley 72 and the pulley 68. A handle 76 with a counter is connected to the other end of the shaft 71.

  In the moving mechanism 60 configured as described above, when the operator rotates the handle 76 with a counter, the pulley 72 is rotated via the shaft 71. This rotation is transmitted to the pulley 68 via the timing belt 74, and the feed screw 64 rotates. As a result, the screwing depth of the feed screw 64 with respect to the female screw hole 45b changes according to the amount of rotation of the feed screw 64, so that the moving frame 44 moves along the arrow X direction. Here, the amount of rotation of the counter-equipped handle 76 can be determined by reading the counter value. Therefore, when the label base material LS having a different width direction dimension is changed, the label handle LS is operated by rotating the handle 76 with a counter so that a counter value corresponding to the width direction dimension of the changed label base material LS is displayed. The initial contact position of the rotary blade 22 with respect to the base material LS can be set to a desired position. After the rotation operation of the counter-equipped handle 76 is completed, it is preferable to operate and fix a fixing handle (not shown) so that the shaft 71 does not rotate with respect to the shaft support member 70.

  In the present embodiment, the case where the operator manually operates the moving mechanism 60 will be described. However, the present invention is not limited to this, and the revolving circular orbit position of the rotary blade 22 is determined by rotating the feed screw 64 with a motor. It may be changed. In this case, when the dimension in the width direction of the label base material LS is input or set through an operation display panel, which will be described later, a motor (not shown) is rotationally driven accordingly, and the revolution circular orbit position can be automatically adjusted.

  FIG. 7 is a block diagram showing an electrical configuration of the label generating apparatus 10. In the figure, the same members as those shown in FIGS. 1 to 6 are denoted by the same reference numerals.

  The label generation device 10 includes a control unit 80. The control unit 80 performs a function of performing overall control of the conveyance operation of the label base material LS by the motors 13, 15, and 17 of the label generation apparatus 10 and the cutting operation of the label base material LS by the rotary blade 22. The control unit 80 includes a microcomputer including a central process unit (CPU), a read only memory (ROM), and a random access memory (RAM). When the CPU executes the control program for the label base material cutting operation stored in the ROM, the label base material LS cutting operation of the rotary blade 22 in the label base material cutting unit 24 and the first to third feed roller pairs 12, 14 and 16 are controlled to intermittently carry the label substrate LS.

  A main control unit 81 is electrically connected to the control unit 80. The main control unit 81 has a function of comprehensively controlling the label mounting operation in the label mounting apparatus that mounts the label L generated by the label generating apparatus 10 on the container. The control unit 80 sends and receives control signals and data related to the label mounting operation to and from the main control unit 81 to control the label generation operation.

  The controller 80 is connected to a servo amplifier 82 a that controls the motor 13 for rotationally driving the first feed roller pair 12. When the control unit 80 outputs a control signal for rotating the first feed roller pair 12 to the servo amplifier 82a, a drive signal is output from the servo amplifier 82a to the motor 13, whereby the motor 13 is rotationally driven. Thus, the first feed roller pair 12 rotates. Further, the detection signal of the pulse encoder 13 a attached to the motor 13 is input to the control unit 80.

  The controller 80 is connected to a servo amplifier 82b that controls the motor 15 for rotationally driving the second feed roller pair 14. When the control unit 80 outputs a control signal for rotating the second feed roller pair 14 to the servo amplifier 82b, a drive signal is output from the servo amplifier 82b to the motor 15. Thereby, the motor 15 is rotationally driven, and the second feed roller pair 14 is rotated. Further, the detection signal of the pulse encoder 15 a attached to the motor 15 is input to the control unit 80. Thus, the second feed roller pair 14 can be controlled independently of the first feed roller pair 12.

  A servo amplifier 82 c that controls the motor 34 for revolving the rotary blade 22 of the cutting device 20 is connected to the control unit 80. When the control unit 80 outputs a control signal for revolving the rotary blade 22 to the servo amplifier 82c, a drive signal is output from the servo amplifier 82c to the motor 34, whereby the motor 34 is rotationally driven to rotate the rotary blade. 22 revolves. A pulse encoder 34a attached to the motor 34 is connected to the control unit 80, and a detection signal of the pulse encoder 34a is input.

  A servo amplifier 82d that controls the motor 40 for rotating the rotary blade 22 of the cutting device 20 is connected to the controller 80. When the control unit 80 outputs a control signal for rotating the rotary blade 22 to the servo amplifier 82d, a drive signal is output from the servo amplifier 82d to the motor 40, whereby the motor 40 is rotated and rotated. The blade 22 rotates. The control unit 80 is connected to a pulse encoder 40a attached to the motor 40, and receives a detection signal of the pulse encoder 40a.

  The controller 80 is connected to a servo amplifier 82e that controls the motor 17 for rotationally driving the third feed roller pair 16. When the control unit 80 outputs a control signal for rotating the third feed roller pair 16 to the servo amplifier 82e, a drive signal is output from the servo amplifier 82e to the third feed motor 17, whereby the motor 17 Is rotated, and the third feed roller pair 16 rotates. Further, a detection signal of a pulse encoder 17 a attached to the motor 17 is input to the control unit 80. Thus, the third feed roller pair 16 can be controlled independently of the first feed roller pair 12 and the second feed roller pair 14.

  A mark sensor 18 is connected to the control unit 80, and an output signal of the mark sensor 18 is input. The control unit 80 detects the reference mark M of each label L on the label base material LS between the first feed roller pair 12 and the second feed roller pair 14 by the output signal from the mark sensor 18. Recognize timing. The control unit 80 calculates the transport amount of the label base material LS based on the timing at which the reference mark M is detected, and the first to third feed rollers so that the label base material LS is intermittently transported by the calculated transport amount. The motors 13, 15, and 17 of the pairs 12, 14, and 16 are controlled.

  The control unit 80 is connected to an operation display board 84 for an operator to make various settings related to the label generation operation and to display the state of the label generation operation. The operation display board 84 has a touch panel type display unit. For example, the operator can generate the label L generation speed (for example, the number of labels generated per minute), the width dimension of the label base LS, and the rotation through the touch panel. When the rotation speed of the blade 22 is input, an operation signal corresponding to the input is output to the control unit 80. Further, display data from the control unit 80 is input to the operation display panel 84, and display contents corresponding to the display data are displayed on the display unit.

  Next, with reference to FIGS. 8 to 10, the adjustment of the revolving circular orbit position T of the rotary blade 22 when the width direction dimension of the label base material LS is changed in the cutting apparatus 20 having the above-described configuration will be described. To do.

  FIG. 8A is a partially enlarged view and FIG. 8B is a top view showing the revolving circular orbit position of the rotary blade when cutting the label base material LS having the width direction dimension W1 in the cutting device 20.

  As shown in FIG. 8B, in the cutting device 20 of the present embodiment, the label blade LS is cut by revolving while rotating the rotary blade 22. In order to cut the end portion of the label base material L (ie, the end portion of the label L) in a clean state at the time of cutting, the peripheral edge portion 22a of the revolving moving rotary blade 22 is the end portion in the width direction of the label base material LS. From this, it has been confirmed that it is preferable to first set the label substrate LS so as to contact at a desired position P, which is inward by a predetermined dimension B of about several mm to 10 mm. The reason is that, since the label base LS is formed of a flexible resin film, when the peripheral edge 22a of the rotary blade 22 that has revolved first comes into contact with the end in the width direction of the label base LS, the label base LS This is because bending due to the inner end of the width direction being pushed inward causes the cut end to be disturbed. Depending on the material, thickness, stretchability, rigidity, and the like of the label base material LS, the above-described cutting may be performed even if the peripheral edge portion 22a of the rotary blade 22 is entered so as to cut from the end in the width direction of the label base material LS. The edge may not be disturbed. In that case, what is necessary is just to cut | disconnect the label base material LS from the width direction edge part, without performing the adjustment which aimed at the desired position P as mentioned above.

In the example shown in FIG. 8B, the width direction dimension W1 of the label base material LS is, for example, 120 mm. In this case, the distance between the rotation center axis O, which is the revolution center of the rotary blade 22, and the label substrate LS is set to A1. Naturally, this distance A1 is set to a length shorter than the radius H of the revolution circular orbit T of the rotary blade 22 (= the revolution radius R of the rotary blade 22 + the radius R ₂₂ of the rotary blade ₂₂ ). The distance A1 between the rotation center axis O and the label base LS is adjusted by the moving mechanism 60 so that the position where the rotary blade 22 starts to hit the label base LS becomes the desired position P as described above.

  FIG. 8B shows a virtual straight line connecting the rotation center O ′ and the rotation center O of the rotary blade 22 at a position where the peripheral edge 22a of the rotary blade 22 contacts the predetermined position P of the label base LS. The angle 25 forms with the imaginary straight line 29 connecting the revolution center O and the width direction center of the label substrate LS is indicated by θ. This angle θ corresponds to the entry angle of the peripheral edge 22a of the rotary blade 22 with respect to the label base LS, and as shown in FIG. 8A, the peripheral edge of the rotary blade 22 from a predetermined position P on the label base LS. 22a is the same as the approach angle θ in the direction of cutting (arrow F direction). This approach angle θ is set to about 15 to 45 degrees, more preferably about 15 to 30 degrees.

  FIG. 9A is a top view showing the revolving circular orbit position of the rotary blade when cutting the label base material LS having a width direction dimension W2 smaller than that in FIG. 8B in the cutting device 20, and FIG. ) Is a top view showing the revolution circular orbit position of the rotary blade when cutting the label base material LS having a width direction dimension W3 larger than FIG. 8B.

  As shown in FIG. 9A, when the label base material LS (for example, W2 = 90 mm) whose width direction dimension W2 is narrower than that in FIG. 8B is changed, the revolution circular orbit position T of the rotary blade 22 is changed. It moves in the direction away from the label substrate LS. Specifically, using the moving mechanism 60, the moving frame 44 (see FIG. 3) is set such that the distance A2 between the rotation center axis O and the label base LS is longer than that shown in FIG. ) Is adjusted (A2> A1). Thereby, even when the label base material LS is changed to be narrow, the position where the rotary blade 22 starts to hit the label base material LS can be set to the desired position P.

  Conversely, as shown in FIG. 9A, when the label base material LS (for example, W3 = 190 mm) whose width direction dimension W3 is wider than that in FIG. The position T is moved to the label base material LS side. Specifically, using the moving mechanism 60, the position of the moving frame 44 is adjusted so that the distance A3 between the rotation center axis O and the label base material LS is shorter than that shown in FIG. Adjust (A3 <A1). Thereby, even when the label base material LS is changed to be wide, the position where the rotary blade 22 starts to hit the label base material LS can be set to the desired position P.

  As described above, according to the label generating apparatus 10 of the present embodiment, even when the width direction dimension of the label base material LS is changed by the rotary blade approach state changing unit, the width direction end of the label base material LS is changed. The revolution circular orbit position T of the peripheral edge portion 22a of the rotary blade 22 with respect to the label base material LS can be changed so that the peripheral edge portion 22a of the rotary blade 22 comes into contact with the label base material LS at a desired position P close to the inside. . Further, by changing the revolution circular orbit position T in this way, the approach angle θ (see FIG. 8B) when the rotary blade 22 cuts into the label base material LS from the predetermined position P is about 15 degrees. It can be adjusted within a range of about ˜45 degrees (more preferably about 15 degrees to 30 degrees). Thereby, adjustment of the approach state of the rotary blade 22 can be performed easily and rapidly about the label base material LS from which the width direction dimension differs. Further, the applicable range in the width direction of the label base material LS is, for example, 90 mm to 120 mm in the past, and is expanded to, for example, 90 mm to 190 mm. As a result, the versatility of the label generating apparatus 10 is improved.

  FIG. 10 is a diagram for explaining the rotational direction and the rotational speed of the rotary blade 22. In the cutting device 20 of the present embodiment, the rotation direction of the rotary blade 22 (arrow r3 direction) is opposite to the revolution direction of the rotary blade 22 (that is, the rotation direction of the swivel arm 30 and the arrow r4 direction). The reason for this is that when the rotating rotary blade 22 starts to hit the label base material LS, a force that pulls the label base material LS to the outside acts, and the label base material can be cut in a drawn state. This is because the cut end face of is finished beautifully.

  In this case, the rotation speed of the rotary blade 22 is preferably set to about 3 to 7 times, more preferably about 4 to 6 times the revolution speed of the rotary blade 22, for example, about 5 times. The degree is most preferable. The reason is as follows.

  The diameter of the revolution circular orbit T at the peripheral edge of the rotary blade 22 is a length (D1 + D2) obtained by adding the diameter D2 of the rotary blade 22 to the revolution diameter D1, and the circumference of the revolution circular orbit T is π (D1 + D2). . Accordingly, the peripheral speed Vk of the peripheral edge of the rotary blade due to revolution is Vk = π (D1 + D2) × N1 when the revolution speed N1 (rpm). On the other hand, since the peripheral length of the rotary blade 22 is πD1, the peripheral speed Vg due to the rotation of the rotary blade 22 is Vg = πD1 × N2 when the rotational speed N2 (rpm) of the rotary blade 22 is set. Since the revolution direction and the rotation direction of the rotary blade 22 are opposite, when Vk = Vg, the peripheral speed due to the revolution of the peripheral portion 22a of the rotary blade 22 is offset by the peripheral speed due to the rotation, and apparently the rotary blade 22 Is equivalent to not rotating.

Specifically, since N1 = Vk / π (D1 + D2) and N2 = Vg / πD1, the rotation speed ratio N2 / N1 = Vg / πD1 ÷ Vk / π (D1 + D2). Here, when the condition of Vk = Vg is substituted, the rotation speed ratio N2 / N1 can be expressed by the following equation (1).
N2 / N1 = Vg / π (D1 + D2) × π (D1 + D2) / Vg
= (D1 + D2) / D1 (1)

  Therefore, when the ratio N2 / N1 between the rotational speed N2 of the rotary blade 22 and the revolution direction N1 satisfies the above formula (1), the peripheral speed Vk due to the revolution of the peripheral edge portion 22a of the rotary blade 22 is determined by the peripheral speed Vg due to the rotation. It is canceled out, and it appears that the rotary blade 22 is not rotating. As a specific example, when the revolution diameter D1 of the rotary blade 22 is 250 mm and the diameter D2 of the rotary blade 22 is 150 mm, (250 mm + 150 mm) / 150 mm = 2.67 times and the speed of the peripheral edge 22a of the rotary blade 22 is relatively zero. become. If it becomes so, the cutting condition of the rotary blade 22 with respect to the label base material LS becomes dull, and the cut end surface of the label base material LS tends to become rough. Therefore, in order to finish the cut end face of the label L neatly, it is preferable that the rotation speed N2 of the rotary blade 22 is about three times or more the revolution speed N1 of the rotary blade 22.

  On the contrary, when the rotation speed N2 of the rotary blade 22 is larger than 7 times the revolution speed N1, the rotation speed becomes too fast, so that the cutting end surface of the label base LS and the surface other than the peripheral edge portion of the rotary blade 22 This is because the film material and the printed layer are liable to be left out due to rubbing. Therefore, in order to suppress the generation of debris, it is preferable that the rotation speed N2 of the rotary blade 22 is not more than about 7 times the revolution speed N1.

  FIGS. 11A and 11B are diagrams showing a modification in which the revolving circular orbit position of the rotary blade 22 is changed by adjusting the length of the turning arm 30A in the cutting device of the label generating device 10. FIG. The swivel arm 30A of this modified example is configured by connecting a rotating member 31a coupled to a support shaft 28 (see FIGS. 3 and 4) and two arm tip portions 31b through screw shafts 31c. According to this configuration, the distance between the rotating member 31a and the arm tip portion 31b can be changed by rotating the arm tip portion 31b screwed to the screw shaft 31c, and the arm radius can be adjusted. .

  More specifically, as shown in FIG. 11A, the revolution that is the revolution trajectory of the peripheral edge portion 22 a of the rotary blade 22 is achieved by bringing the rotary member 31 a into contact with the arm tip portion 31 b (arm radius ra). The radius H2 of the circular orbit position T2 is minimized, and can be applied to the cutting of the label base material LS whose width direction dimension W2 is narrow as in the case of FIG. On the other hand, as shown in FIG. 11B, the rotation member 31a and the arm tip portion 31b are separated from each other (arm radius rb (rb> ra)), so that the peripheral portion 22a of the rotary blade 22 revolves. The radius H3 of the revolution circular orbit position T3 which is a locus becomes large, and can be applied to the cutting of the label base material LS having a wide width direction dimension W3 as in the case of FIG. 9B.

  In this way, the turning arm 30A is configured to be extendable and retractable, and by providing a changing mechanism that changes the arm length from the rotation center axis O of the turning arm 30A to the rotation center position of the rotary blade 22, the revolution of the rotary blade 22 is achieved. The circular orbit position can be changed, and as a result, the setting for generating the label L by cutting the label base material LS having different width direction dimensions can be easily performed. In this case, the moving mechanism 60 (see FIG. 3) for moving the moving frame 44 relative to the fixed frame 21 can be omitted.

Second Embodiment
Next, with reference to FIGS. 12 to 15, a label generation apparatus 10 </ b> A according to the second embodiment will be described. FIG. 12 is a right side view of the label generating apparatus 10A according to the second embodiment. Below, the same code | symbol is attached | subjected to the structure same as the label production | generation apparatus 10 of 1st Embodiment mentioned above, and the overlapping description is not performed.

  As shown in FIG. 12, the cutting device 20A in the label generating device 10A of the present embodiment includes a clamp device 120 that clamps the label base material LS at positions near both the upper and lower sides of the label base material cutting position K. Instead, the protective member 54 in the cutting device 20 of the first embodiment is omitted. Other configurations are the same as those of the cutting device 20 of the first embodiment.

  13A is a top view of the clamping device 120 shown in FIG. 12, and FIG. 13B is a side view of the clamping device 120. FIG. FIGS. 14A and 14B are a top view and a side view showing a state in which the clamp device 120 clamps the label base material LS. As shown in FIGS. 13A and 13B, the clamp device 120 includes an upper clamp member 122, a lower clamp member 124, and an actuator 130.

  The upper clamp member 122 includes an inner clamp bar 122a and an outer clamp bar 122b. The inner clamp bar 122a (the same applies to other clamp bars) is formed of, for example, a metal bar such as a stainless steel round bar. Two legs of the inner clamp bar 122 a are connected to the first output part 134 of the actuator 130. The outer clamp bar 122 b is formed in a similar shape slightly larger than the inner clamp bar 122 a, and two legs are connected to the second output part 136 of the actuator 130.

  As shown in FIG. 13A, a label base material LS that is intermittently conveyed is passed between the front end portion of the inner clamp bar 122a and the front end portion of the outer clamp bar 122b. In the state shown in FIG. 13A, since the actuator 130 is in an inoperative state, the inner clamp bar 122a and the outer clamp bar 122b are in a state in which the label base material LS is released (released).

  As illustrated in FIG. 13B, the lower clamp member 124 is disposed below the upper clamp member 122 with a slight gap G therebetween. The gap G is preferably set to about twice (about 3 to 4 mm) the thickness of the rotary blade 22 (for example, 1.7 mm). The lower clamp member 124 is disposed in parallel with the upper clamp member 122.

  Similar to the upper clamp member 122, the lower clamp member 124 includes an inner clamp bar 124a and an outer clamp bar 124b. The inner clamp bar 124 a is formed in the same shape as the inner clamp bar 122 a of the upper clamp member 122, and two legs are connected to the first output part 134 of the actuator 130. Similarly, the outer clamp bar 124 b is formed in the same shape as the outer clamp bar 122 b of the upper clamp member 122, and two legs are connected to the second output portion 136 of the actuator 130.

  The actuator 130 includes a main body part 132, a first output part 134 that can be moved forward and backward at one end of the main body part 132 (that is, the side facing the label base material LS), and the other side of the main body part 132. In other words, the second output portion 136 is provided at the end portion (that is, the side opposite to the label base material LS) so as to be movable forward and backward. The actuator 130 has a main body 132 attached to the fixed frame 21 of the label generating apparatus 10 by a bracket.

  Actuator 130 operates in response to a control signal transmitted from control unit 80 (see FIG. 7). For example, a voice coil motor is preferably used for the actuator 130. The voice coil motor can operate at a high frequency of, for example, 10,000 Hz or more by itself, and is suitable for increasing the label generation speed.

  When the actuator 130 is operated, the first output part 134 protrudes from the main body part 132 in the direction of the arrow Y1 and pushes the inner clamp bars 122a, 124a of the upper and lower clamp members 122, 124 toward the label base LS, The second output part 136 projects from the main body part 132 in the direction of the arrow Y2, and attracts the outer clamp bars 122b and 124b of the upper and lower clamp members 122 and 124 toward the label base material LS. Thereby, the label base material LS is clamped by the upper clamp member 122 at a position near the upper side of the label base material cutting position K as shown in FIGS. Is clamped by the lower clamp member 124 at a position in the vicinity of the lower side. In the clamped state as shown in FIG. 14B, the peripheral edge 22a of the rotary blade 22 of the cutting device 20A enters across between the upper clamp member 122 and the lower clamp member 124, The label substrate LS is cut.

  FIG. 15A is an enlarged side view showing a state when the label base material LS is cut in the cutting apparatus 20A of the second embodiment, and FIG. 15B is a label group in the cutting apparatus as a comparative example. It is a side view which expands and shows the state when material LS is cut | disconnected.

  When cutting the label base LS, as shown in FIG. 15B, the label base LS can be simply supported by contacting the back side of the label base LS at a position near the top and bottom of the height position through which the rotary blade 22 passes. When the material LS is pushed so as to escape from the rotary blade 22, for example, a distorted cut surface such as a wavy cut surface or a cut surface with a beard may be formed. This may occur, for example, when the tension of the label substrate LS located between the second feed roller pair 14 and the third feed roller pair 16 is loosened for some reason.

  On the other hand, in the cutting device 20A of the present embodiment, as shown in FIG. 15A, the label base material LS is located at the upper and lower sides of the label base material cutting position K in the vicinity of the upper and lower clamp members 122 and the lower clamp member. In a state of being clamped by 124, it is cut by the rotary blade 22. Therefore, the label base material LS can be stably cut in a moderately tensioned state. As a result, it is possible to prevent the cut surface of the label L from being disturbed.

  FIG. 16 is a top view showing a specific example of the rotational angle position of the rotary blade 22 in the cutting apparatus 20A of the second embodiment, and FIG. 17 shows the second and third feed roller pairs 14 and 16, the rotary blade 22, It is a timing chart which shows operation of clamp device 120.

  In the example shown in FIGS. 16 and 17, the label base material LS having a width-direction dimension W = 120 mm is cut using a rotary blade 22 having a diameter D2 = 150 mm that rotates while revolving with a revolution diameter D1 = 250 mm. Show. The angle range is set to 0 ° (= 360 °) at the position where the rotary blade 22 is farthest from the label base material LS, and 90 °, 180 °, and 270 ° counterclockwise (arrow r4 direction). . In FIG. 17, the uppermost stage is the conveying operation of the second feeding roller pair 14, the second stage is the conveying operation of the third feeding roller pair 16, the third stage is the rotating operation of the rotary blade 22, and the fourth stage is the clamping device. 120 operations are represented. Further, the following time is a time calculated based on the revolution period 83.33 msec of the rotary blade 22 when the label generation speed is set to 720 sheets / min.

  Referring to FIGS. 16 and 17, the rotary blade 22 cuts the label base material LS to generate one label L during one revolution revolution from 0 ° to 360 °. The second feed roller pair 14 and the third feed roller pair 16 cooperate to convey the label base material LS vertically downward, and at the timing when the rotary blade 22 is at a position of an angle of 133 °, the second feed roller pair 14 and the third feed roller pair 16 The cutting position C is stopped at the label base material cutting position K.

  The clamping device 120 starts the clamping operation at the timing when the rotary blade 22 is positioned at 80.2 °, and completes the clamping of the label base material LS at the timing of 145 °. When a voice coil motor is used as the actuator 130 of the clamp device 120, the inner clamp bars 122a and 124a and the outer clamp bars 122b and 124b of the upper and lower clamp members 122 and 124 have a stroke of 3 mm for the label substrate LS. Can be brought into contact (ie, clamping is completed) with a pressing force of 6N. In this case, the time required for completing the clamping operation from the same angle of 80.2 ° to 145 ° is 15 msec, and the clamping operation can be completed in about 2.8 msec after the conveyance of the label base material LS is stopped.

  After the conveyance of the label base material LS is stopped at the same angle of 133 °, the cutting of the label base material LS is started at the same angle of 156.9 °, and the cutting is completed at the same angle of 203.1 °. . The angular range during this cutting operation is 46.2 °, and the corresponding cutting time is 10.69 msec.

  When the cutting of the label base material LS is completed, the third feed roller pair 16 starts conveying the cut label L at the same angle of 227 °. The second feed roller pair 14 (in cooperation with the first feed roller pair 12) starts conveying the label base material LS at the same angle 243 ° delayed.

  Prior to the third feed roller pair 16 starting to convey the label L, the clamp device 120 starts a release operation (that is, a clamp release operation) at the same angle of 215 °. Accordingly, the label L can be conveyed by the third feed roller pair 16. Then, the clamp device 120 completes the release operation in the required time of 15 msec, as in the clamp operation.

  As described above, in the cutting device 20A according to the present embodiment, when the voice coil motor is used as the actuator 130 of the clamp device 120, the label base LS can be clamped and released with a sufficient clamping force and in a short time. , 720 sheets / min can be sufficiently dealt with.
