The label die-cutting devices such as Patent Document 1 and Patent Document 2 cannot drive the rotary cylinder or the anvil roll up and down at high speed.

It was a device.
Conventionally, the rotary cylinder and the anvil roll have a cylindrical shape with substantially the same diameter because it is necessary to keep the angle of contact of the cutting blade at an appropriate obtuse angle. That is, if the anvil roll is simply made smaller in diameter than the rotary cylinder to reduce the weight, the blade contact angle cannot be kept at an obtuse angle of an appropriate size, and a suitable die cutting cannot be performed.

Hereinafter, a label die cutting apparatus and a label die cutting method according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic view showing a state in which a label is punched from a roll label in the label punching apparatus of the present embodiment.
As shown in FIG. 1, the label die cutting apparatus 10 applies a roll label 11. The roll label 11 includes a label S to be punched and a label member R having no release paper printed with an eye mark 12 such as black for informing the start position of the label S to be punched. Then, the label die cutting apparatus 10 punches the label S portion of the label member R, and the punched label S is pasted on the product by a pasting mechanism or the like (not shown). Further, the remaining portion T of the label member R remaining after the die cutting is sequentially wound by a remaining label winding mechanism (not shown). The tip of the label S on the label member R is detected by the optical reflection type eye mark sensor 13.

Next, the structure of the label die cutting apparatus 10 will be described.
The label die-cutting device 10 includes a label transport unit 14 that sends out a roll label 11 and a rotary unit 15 that includes a rotary cylinder 17 around which a rotary blade portion 16 is wound. Further, the label die-cutting device 10 includes an anvil unit 18 equipped with an anvil roll 19 and an auxiliary pressure mechanism 20 for absorbing the elastic force due to the pressure applied to the rotary blade portion 16 of the anvil roll 19 (see FIG. 4). And comprising.
Here, the rotary blade part 16 has a plurality of die cutting blades 21 formed in a plurality of different shapes, and has a plurality of irregular index marks 22 indicated by these die cutting blades 21 on the side portion. A plurality of deformed index marks 22 are detected by an optical reflection type index sensor 23 to selectively set which die cutting blade 21 is used for die cutting.

  The label die cutting device 10 sandwiches the label member R fed from the roll label 11 between the anvil roll 19 of the anvil unit 18 and the rotary cylinder 17 of the rotary unit 15. Then, the loaded roll label 11 is pressurized by the rotary blade portion 16 and the anvil roll 19, and the die-cut label S and the remaining portion T after die-cutting are sent out. As for the processing of the die-cut label S and the remaining portion T after die-cutting, it is processed by a label discharge portion (not shown) and a label winding portion arranged on the downstream side.

  The label transport unit 14 includes a roll label transport drive motor 24 that is a step motor, and a gear reduction mechanism 25 connected to the roll label transport drive motor 24. The label transport unit 14 includes a plurality of label transport rollers 26 connected to a gear reduction mechanism 25.

  The rotary unit 15 includes a rotary cylinder driving motor 27 that is a step motor for rotating the rotary cylinder 17. Further, the rotary unit 15 includes a gear reduction mechanism 28 connected to a rotary cylinder driving motor 27.

Next, details of the anvil unit 18 will be described. FIG. 2 is an external perspective view of the anvil unit in the label die cutting apparatus of the present embodiment. FIG. 3 is an external perspective view of the auxiliary pressure unit in the label die cutting apparatus of the present embodiment.
As shown in FIGS. 2 and 3, the anvil unit 18 includes an anvil unit base 29 that is a support plate and an anvil table vertical drive motor 30.
The anvil unit 18 includes an anvil table vertical drive gear reduction mechanism 31 geared to an anvil table vertical drive motor 30. The anvil unit 18 includes an anvil table vertical drive first shaft 32 supported by an anvil unit base 29 so as to be rotatable in the horizontal direction.

  The anvil unit 18 includes a pair of helical toothed anvil table vertical driving first gears 33 coupled to the anvil table vertical driving first shaft 32. The anvil unit 18 includes an anvil table vertical drive second shaft 34 that is rotatably supported by the anvil unit base 29 in the vertical direction.

The anvil unit 18 includes a pair of helical anvil table vertical drive second gears 35 coupled to the anvil table vertical drive second shaft 34. The anvil unit 18 includes a lower anvil table 36 in which an anvil table vertical drive second shaft 34 is rotatably inserted. The anvil unit 18 includes an upper anvil table 37 via the auxiliary pressure mechanism 20. The anvil unit 18 has a male screw 38 (see FIG. 4) at the tip of the second shaft 34 for driving the anvil table up and down. The male screw 38 is gear-coupled to a female screw 39 (see FIG. 4) formed on the lower anvil table 36.
Then, the anvil unit 18 rotatably supports the anvil roll 19 with a pair of side plates 40 on the upper anvil table 37. The anvil roll 19 has a metal central shaft 41 and an organic polymer member 42 having high hardness and elasticity.
The organic polymer member 42 is deposited on the outer peripheral surface of the central shaft 41. The organic polymer member 42 has a hardness of 90 or more, for example.

  An anvil table position detection encoding plate 43 is attached to the first shaft 32 for anvil table vertical drive. The anvil table position detection encoding plate 43 detects the amount of vertical movement displacement of the lower anvil table 36 in synchronization with the rotation of the first shaft 32 for vertical driving of the anvil table. An anvil table vertical position sensor 44 is attached to the anvil unit base 29. The anvil table vertical position sensor 44 detects the vertical movement displacement of the lower anvil table 36 in units of vertical movement pitch (h1). The anvil table vertical position sensor 44 is an optical shading sensor. The anvil table vertical position sensor 44 detects and counts the presence / absence of the slit 45 provided in the anvil table position detection encoding plate 43 and the rotation direction as pulse signals.

An anvil table origin light shielding plate 46 is attached to the lower anvil table 36. The anvil unit base 29 is provided with an optical shading type anvil table origin detection sensor 47.
The anvil table origin light shielding plate 46 and the anvil table origin detection sensor 47 are adjusted so that the height position of the anvil roll 19 is the same as the height of the label member R. The anvil table origin detection sensor 47 is an optical shading sensor. The anvil table origin detection sensor 47 detects the timing at which the tip of the anvil table origin light shielding plate 46 is shielded by the vertical drive of the lower anvil table 36. The anvil table origin detection sensor 47 obtains an origin position adjusted so that the height of the anvil roll 19 is the same as the height of the label member R.

  The anvil table vertical drive motor 30 is a power source that generates rotational power. The rotational power generated by the anvil table vertical drive motor 30 is transmitted to the anvil table vertical drive gear reduction mechanism 31. The anvil table vertical drive gear reduction mechanism 31 rotates the anvil table vertical drive first shaft 32 by the rotational power transmitted from the anvil table vertical drive motor 30. The first anvil table vertical drive shaft 32 rotates together with the anvil table vertical drive first gear 33.

By rotating the first anvil table vertical drive gear 33, the rotational power of the anvil table vertical drive first gear 33 is transmitted to the anvil table vertical drive second gear 35. The anvil table vertical drive second gear 35 rotates together with the anvil table vertical drive second shaft 34. As the anvil table vertical drive second shaft 34 rotates, the lower anvil table 36 is driven up by the engagement of the male screw 38 and the female screw 39.
As a result, the anvil roll 19 rises with respect to the rotary cylinder 17 via the auxiliary pressure mechanism 20, and the anvil roll 19 pressurizes the rotary cylinder 17.

Next, the structure of the auxiliary pressure mechanism 20 will be described. 4A and 4B are operation explanatory views of the auxiliary pressurizing unit shown in FIG. 3, in which FIG. 4A is a state diagram in which pressure is applied to the ascending side, and FIG.
As shown in FIGS. 4A and 4B, the auxiliary pressure mechanism 20 includes an auxiliary pressure spring 48, a first pressure adjustment member 49, and a pair of second pressure adjustment members 50. Prepare.
The auxiliary pressure spring 48 is a torsion coil spring, and its lower end is fixed to the lower anvil table 36.

The first pressure adjusting member 49 is formed in an isosceles trapezoidal shape and has a pair of inclined surfaces 51. The first pressure adjusting member 49 is fixed to the upper end portion of the auxiliary pressure spring 48. The pair of second pressure adjusting members 50 each have an inclined surface 52 that is in sliding contact with one of the inclined surfaces 51 of the first pressure adjusting member 49. The pair of second pressure adjustment members 50 mesh with a pressure adjustment screw 53 disposed at the center of the first pressure adjustment member 49. The pair of second pressure adjusting members 50 are supported by the lower surface of the upper anvil table 37 in a semi-fixed manner. Therefore, the pair of second pressure adjusting members 50 are slid and moved in the direction in which they approach each other or in the direction in which they separate from each other when the pressure adjusting screw 53 is turned.
Thereby, the space | interval dimension of a pair of 2nd pressurization adjustment member 50 with respect to the 1st pressurization adjustment member 49 can be adjusted.

  Note that the structure of the auxiliary pressurizing mechanism 20 does not adjust the gap dimension between the lower anvil table 36 and the upper anvil table 37. And this structure is a structure which pushes back the pressure reaction force with respect to the anvil roll 19 on the lower anvil table 36 with the Young's modulus of a spring. That is, the structure of the auxiliary pressurizing mechanism 20 has a role of maintaining the deformation (maintaining the die cutting angle α degrees) while canceling the deformation reaction force of the organic polymer member 42 deposited on the anvil roll 19. Therefore, the structure of the auxiliary pressurizing mechanism 20 has a role of auxiliary pressurization that suppresses a decrease in the pressurizing force required for die cutting. These anvil drive control, table height control, and related origin signal detection and encode signal detection processes are processed by the main control unit 60 described later.

Next, the edge contact of the label die cutting apparatus 10 will be described in detail. FIG. 5 is an enlarged view of a main part for explaining the contact of the label die cutting apparatus according to this embodiment. FIG. 6 is a characteristic diagram per blade of the label die cutting apparatus of the present embodiment.
As shown in FIGS. 5 and 6, in the label die cutting apparatus 10, the contact angle between the die cutting blade 21 and the anvil roll 19 is set to a predetermined angle (α degrees) or less.
The die cutting blade 21 bites into the organic polymer member 42 deformed by the pressurization. Here, a point where the die cutting blade 21 bites into the organic polymer member 42 is a cutting point (P) of the label member R. Further, a point (Q) is defined as a point where the die cutting blade 21 bites into the label member R just before the organic polymer member 42 comes into non-contact with the label member R is about 70% of the thickness D of the label member R. In the present embodiment, the angle α is an angle formed by the label member horizontal line and the straight line PQ.
Further, the horizontal component distance (offset d) of the line segment PQ is a distance required from the time when the label member R is cut to about 70% of the thickness D of the label member R to the completion of the cutting of the label member R. In this embodiment, the offset d is about 2 mm. Furthermore, the remaining thickness when the die cutting blade 21 bites in about 70% of the thickness D of the label member R at the point Q is 0.04 mm. Therefore, α = arctan (0.04 mm / 2 mm) = 1.14 degrees. It refers to the use of pressure, hardness and elastic property materials that can obtain angles below this angle.
That is, the contact angle (angle α) between the anvil roll 19 and the die punching blade 21 is 0 degree with respect to the line from the front end of the label member R toward the rear end (on the rotary cylinder 17 side). Is set to 1.14 degrees or less. In order to facilitate the design and manufacture of the label die cutting apparatus 10, the angle α may be set to 1.2 degrees or less.
The contact angle between the anvil roll 19 and the die cutting blade 21 when the line from the rear end to the front end of the label member R is 0 degree is the organic polymer member 42 disposed on the outer peripheral surface of the anvil roll 19. Is smaller than the absolute value of the angle α. For example, the contact angle between the anvil roll 19 and the die cutting blade 21 when the line from the rear end to the front end of the label member R is 0 degree is 0.8 degrees or less in the downward direction (anvil roll 19 side). Is set.
Thereby, in this embodiment, when the anvil roll 19 is deformed, the blade contact angle (apparent blade contact angle) when the anvil roll 19 is deformed is the case where the anvil roll 19 is not deformed and has a circular cross section. It is different from the blade contact angle. That is, as in the case where the diameter of the anvil roll 19 is larger than the actual diameter of the anvil roll 19 and substantially the same as the diameter of the rotary cylinder 17, appropriate die cutting can be performed.

Next, the configuration of the main control unit 60 will be described. FIG. 7 is a block configuration diagram of the main control unit of the label die cutting apparatus according to the present embodiment.
As shown in FIG. 7, the main control unit 60 controls the entire label punching apparatus 10 and sets information necessary for operation control in the common memory 65. The main control unit 60 issues a command to each processing unit for monitoring and controls the overall processing flow. The main control unit 60 mainly includes a rotary cylinder drive processing unit 61, a roll label conveyance drive processing unit 62, an anvil roll up / down drive processing unit 63, a main control processing unit 64, and a common memory 65.

  The rotary cylinder drive processing unit 61 is electrically connected to the rotary cylinder drive motor 27 through the rotor cylinder motor drive circuit 66. The rotary cylinder drive processing unit 61 receives a sensor signal from the index sensor 23 through the index sensor detection circuit 67. The rotary cylinder drive processing unit 61 performs driving of the rotary cylinder 17 and index detection on the rotary blade part 16. Then, the rotary cylinder drive processing unit 61 manages the current position information of the rotary cylinder 17 and sets the index detection result in the common memory 65.

  The roll label conveyance drive processing unit 62 is electrically connected to the roll label conveyance drive motor 24 through a roll label conveyance motor drive circuit 68. The roll label conveyance drive processing unit 62 receives a sensor signal from the eye mark sensor 13 through the eye mark sensor detection circuit 69. The roll label conveyance drive processing unit 62 performs roll label conveyance driving for conveying the roll label 11 and detection of the eye mark 12 on the roll label 11. The roll label conveyance drive processing unit 62 manages the punching start position information of the roll label 11 and sets it in the common memory 65.

  The anvil roll vertical drive processing unit 63 is electrically connected to the anvil table vertical drive motor 30 through the anvil table vertical motor drive circuit 70. The anvil roll vertical drive processing unit 63 receives a sensor signal from the anvil table vertical position sensor 44 (position detection encoder sensor) through the anvil sensor detection decoding circuit 71. The anvil roll up / down drive processing unit 63 is supplied with a sensor signal from the anvil table origin detection sensor 47 (origin detection sensor) through the anvil sensor detection decoding circuit 71. The anvil roll up / down drive processing unit 63 manages the up / down drive of the anvil roll 19 and sets state information in the common memory 65.

  Note that stepping motors are employed as the rotary cylinder driving motor 27, the anvil table vertical driving motor 30, and the roll label transport driving motor 24. The gear ratios of the motors 24 and 27 are configured so as to obtain the minimum step feed amount (S1) necessary for punching the label member R in advance. Similarly, the anvil table vertical drive motor 30 has a mechanism having a sufficient vertical drive amount obtained by adding the height of the die cutting blade 21 and the thickness of the label member R, etc., and the drive stroke (H) and the step feed amount. (h1).

Next, the encode signal of the anvil unit 18 of the label die cutting apparatus 10 will be described. FIG. 8A is a timing chart of the encode signal of the anvil unit of the label punching apparatus of this embodiment. FIG. 8B is a schematic diagram of an anvil table position detection encoding plate. FIG. 8 (c), encoding the sensor at the timing indicated by _t 1 ~t ₈ in FIG. 8 (a) ()
As shown in FIG. 8 (a), in the anvil unit 18, the vertical drive and height (pressure position) of the anvil roll 19 are detected by two sensors and used for control. The first sensor is an anvil table origin detection sensor 47, and the second sensor is an anvil table vertical position sensor 44. Specifically, the slit 45 (black portion) of the anvil table position detection encoding plate 43 is detected by an optically transmissive anvil table vertical position sensor 44. That is, the anvil table vertical position sensor 44 has a pair of sensors having different phases. Then, the pair of sensors detects the rotation direction and the rotational movement amount by generating a sensor signal corresponding to the rotation of the anvil table vertical drive first shaft 32. At this time, the anvil table origin light shielding plate 46 moves simultaneously with the driving of the lower anvil table 36. Then, the table height reaches the origin height position (the retracted position of the anvil roll 19) of the anvil roll 19 that is mechanically set in advance.
Thereby, the optical shading type anvil table origin detection sensor 47 is turned on to indicate that it has passed the origin position. If the anvil table vertical drive motor 30 is controlled to return to the position where this signal is turned on, the anvil roll 19 can be stopped at the correct origin position (retracted height position).

Next, the processing flow of the rotation direction (table vertical direction) detected by the anvil unit 18 of the label punching device 10, the movement pulse count, and the origin signal will be described. FIG. 9 is a flowchart for explaining the control flow of the anvil unit for explaining the label die cutting method of the present embodiment.
As shown in FIG. 9, the anvil roll up / down drive processing unit 63 performs addition / subtraction processing for each h1 unit step managed as a step address in response to the “start 1” command. At the same time, the anvil roll up / down drive processing unit 63 obtains the fluctuation of each sensor signal of the anvil table vertical position sensor 44 from the anvil sensor detection decoding circuit 71. Then, information of the anvil sensor detection decoding circuit 71 from the time point t1 to the time point t8 shown in FIG. 8 is obtained and added to or subtracted from the step address. This process is performed by a motor acceleration / deceleration process and an interrupt process (not shown). The step address obtained by the interrupt processing unit is information indicating the height position of the anvil roll 19. And it manages as an absolute position by the state of each sensor signal of the anvil table vertical position sensor 44, and is stored in the common memory 65 (S101-S109).
Thereby, subsequent height control can be performed by the command of a height position.

  In “Start 2”, after the height origin position of the anvil roll 19 is obtained, the anvil roll 19 is lowered. The height of the anvil roll 19 is the same as that of the label conveying roller 26 (the height at which the surface of the label member R does not contact the die cutting blade 21 and there is a slight gap). (S107 to S109).

In “Start 3”, the height of the anvil roll 19 is increased by pressure to a height position HH that contacts the height of the die cutting blade 21 of the rotary blade portion 16. The height of the anvil roll 19 is based on the origin position, and the anvil table vertical drive motor 30 is accelerated and rotated from the stop state to the V speed at the HL height position. Then, the anvil table vertical drive motor 30 is rotated up until the anvil roll 19 reaches the HH height position (S111 to S113).
The up / down movement is controlled by switching the rotation direction of the anvil table vertical drive motor 30 in the CW (clockwise: up) or CCW (counterclockwise: down) direction.

  The main control processing unit 64 performs control to rotate the rotary cylinder 17 to a target index position on the rotary blade unit 16. Therefore, “start 1” to “start 3” commands are appropriately issued to the anvil roll vertical drive processing unit 63. At the same time, in order to remove the start position of the eye mark 12 on the roll label 11 and convey it to the origin, commands of “start 1” to “start 3” are appropriately issued to the anvil roll vertical drive processing unit 63. In a state where the rotary blade portion 16 is being pressurized (HH height position), the anvil roll 19 is stopped and lifted by “start 2”. In “start 3”, the anvil roll 19 is lowered to the HL height position at the designated speed V, and is retracted to a position where the die cutting blade 21 does not contact the label member R and stops.

Next, a control flow of the main control processing unit 64 that performs overall processing of the above-described processes will be described. FIG. 10 is a flowchart for explaining the control flow of the main control processing unit for explaining the label die cutting method according to one embodiment of the present invention.
As shown in FIG. 10, in “start 1”, the anvil roll 19 is lowered to obtain the origin position, and the feed is stopped to the retracted position in order to perform initialization processing of each part. At the same time, index detection processing on the rotary cylinder 17 and eye mark 12 detection processing on the roll label 11 are performed (S201 to S203).

In “Start 2”, the anvil roll 19 is raised from the state prepared in “Start 1” (pressurized state), and the roll label 11 is conveyed. Then, the label member R is die-cut while rotating the rotary cylinder 17 from the position of the target die-cutting blade 21 by the punch length. When the die-cutting of one label S is completed, the anvil roll 19 is lowered, and then the roll label 11 is conveyed for preparation for the next die-cutting. And it conveys from the detection position of the eye mark 12 to the extraction origin, and simultaneously rotates the rotary cylinder 17, and advances the selection of the position of the die cutting blade 21 of the same purpose (S211 to S220).
By repeating these steps in sequence, the label member R can be die-cut by selecting the position of the target die-cutting blade 21.

As described above, according to the label die cutting apparatus 10 of one embodiment of the present invention, the anvil roll 19 is made of the metal center shaft 41 and the center shaft 41 which is vapor-deposited with high hardness and elasticity. And an organic polymer member 42.
Thereby, when the anvil roll 19 comes into contact with the rotary cylinder 17, the organic polymer member 42 is elastically deformed, and the apparent edge contact angle of the die cutting blade 21 with respect to the anvil roll 19 becomes a suitable obtuse angle. For this reason, even if it uses the small diameter anvil roll 19, suitable die cutting can be performed. As a result, the diameter of the anvil roll 19 can be reduced and the weight can be reduced, and the energy required to drive the anvil roll 19 up and down can be reduced. Therefore, the anvil roll 19 can be driven up and down at a higher speed than before by using a power source having an output equivalent to that of the conventional one.
If the speed at which the anvil roll 19 is driven up and down can be increased, the anvil roll 19 operates properly even if the feeding speed of the label member R is increased, so that the speed of the entire die cutting operation can be increased.

Further, according to the label die-cutting device 10, the main control unit 60 controls the rotary cylinder drive system, the anvil roll up / down drive system, and the label transport drive system.
Therefore, according to the label die cutting apparatus 10, the circuit configuration can be simplified.

Then, according to the label punching device 10, the auxiliary pressure mechanism 20 maintains the deformation while canceling the deformation reaction force of the organic polymer member 42 deposited on the anvil roll 19.
Therefore, according to the label die-cutting device 10, the die-cutting angle with respect to the die-cutting blade 21 can be maintained for a long time.

Furthermore, according to the label die-cutting device 10, the contact angle between the anvil roll 19 and the die-cutting blade 21 included in the rotary blade portion 16 is set to 0 ° when the line from the front end to the rear end of the label member R is 0 °. On the other hand, it is set to 1.2 degrees or less.
Therefore, according to the label die-cutting device 10, appropriate die-cutting can be performed. The contact angle may be 1.14 degrees or less.

  According to the label die cutting method of one embodiment of the present invention, the anvil roll 19 can be driven up and down at high speed. For this reason, the feeding speed of the label member R can be increased, and the die cutting amount of the label per unit time can be increased.

  In the label die-cutting method of the present invention, since the die-cut label is affixed to a product or the like, if the label die-cutting speed is slow, the rate at which the product is conveyed is limited. On the other hand, according to the method of the present embodiment that can perform the die-cutting of the label at a high speed, the label can be supplied without delay to the product conveyed at a high speed.

  In addition, the label die cutting apparatus and the label die cutting method of the present invention are not limited to the above-described embodiments, and appropriate modifications and improvements can be made.

As an application of the embodiment described above, the same effect can be obtained by the following method without limiting the vapor deposition treatment to the anvil roll, and it is considered similar to the realization of the present invention.
For example, the extraction origin position (center point lower point) of the rotary cylinder and the center position (upper point) of the anvil roll are shifted in advance by an offset d and face each other. This makes it possible to make an anvil roll with substantially the same diameter. However, the cut surface of the stamped label tends to be slightly inclined.
A plurality of anvil rolls are arranged and the anvil rolls are connected by a steel belt or the like. Thereby, the same effect is acquired by ensuring an apparent large-diameter anvil surface similarly to elastic deformation, and reducing the whole anvil part structure.
Although various structures can be considered as the method for realizing the vertical drive mechanism of the anvil roll, the realization means is not limited.
