Is provided.

  The rotary cylinder drive processing unit 51 is electrically connected to the rotary cylinder drive motor 23 through the rotor cylinder motor drive circuit 57. The rotary cylinder drive processing unit 51 is given a sensor signal from the index sensor 26 through the index sensor detection circuit 58.

  That is, the rotary cylinder drive processing unit 51 sets the start positions (that is, index information) of the first mold extraction blade 32, the second mold extraction blade 33, the third mold extraction blade 34, and the fourth mold extraction blade 35 to the first type. The index mark 37, the second index mark 38, the third index mark 39, and the fourth index mark 40 are detected and detected.

  The rotary cylinder drive processing unit 51 also has a rotary blade portion attached to the rotary cylinder 17 based on a sensor signal obtained by the index sensor 26 reading the management information code encoded in the management information code area 25. 16 types are specified.

  Specifically, the rotary cylinder drive processing unit 51 subsequently reads the management information code area 25 after detecting the first index mark 37. That is, reading of the actual part of the management information code is started by changing from light non-reflective to light reflective at the start edge of the start bit in the management information code area 25 (edge on the tip side of the rotary blade 16). In reading the management information code area 25, the index sensor 26 is referred to three pitches after the start edge of the start bit is detected, and thereafter every five pitches. As a result, “1” and “0” are determined not at the edge of each recess but at the center of each recess. (A ↓ position in FIG. 6).

  When the index sensor 26 reads the management information code area 25, the rotary cylinder drive processing unit 51 acquires a number (code number) for specifying the rotary blade part 16 encoded in the management information code area 25.

  The rotary cylinder drive processing unit 51 recognizes the index information and the code number in accordance with the sensor signal given from the index sensor 26 and sets it in the common memory 55. Accordingly, the type of the rotary blade portion 16 and the current position of the rotary cylinder 17 can be managed based on the information set in the common memory 55.

The roll label transport drive processing unit 52 is electrically connected to the roll label transport drive motor 20 through a roll label transport motor drive circuit 59. The roll label transport drive processing unit 52 operates the roll label transport drive motor 20 that transports the roll label 11. The roll label conveyance drive processing unit 52 is electrically connected to the eye mark sensor 13 through the eye mark sensor detection circuit 60. Thereby, the roll label conveyance drive processing unit 52 receives the sensor signal from the eye mark sensor 13 through the eye mark sensor detection circuit 60 and detects the eye mark 12 on the label member R.
The roll label conveyance drive processing unit 52 sets the punching start position information of the roll label 11 in the common memory 55.

  The anvil roll up / down drive processing unit 53 is electrically connected to the anvil roll up / down drive motor 28 through the anvil roll up / down motor drive circuit 61. The anvil roll up / down drive processing unit 53 is given a sensor signal from the anvil roll sensor 29 through the anvil roll sensor detection circuit 62. The anvil roll vertical drive processing unit 53 sets status information indicating the vertical position of the anvil roll 19 in the common memory 55.

  Further, the common memory 55 stores an extraction information file 56 including setting information unique to each of the plurality of rotary blade portions 16. The punching information file 56 corresponds to the code number of the rotary blade portion 16 encoded in the management information code area 25, and the number, height, length, width, gap amount, and the corresponding label S of the punching blades. This is a file in which configuration information, an optimum die pressing force and speed, and a conveyance speed of the label member R (hereinafter collectively referred to as “setting information”) are stored.

  The main control processing unit 54 refers to the extraction information file 56 and acquires setting information corresponding to the rotary blade unit 16 attached to the rotary cylinder 17. Thereby, in the main control unit 30, an operation procedure including the rotation operation of the rotary cylinder 17, the vertical operation of the anvil roll 19, and the conveyance speed of the label member R in the label conveyance unit 14 is set.

  Next, the effects of the label die cutting device 10, the rotary blade portion 16, and the label die cutting method of the present embodiment will be described together with the operation during use of the label die cutting device 10. 8A and 8B are flowcharts for explaining the control flow of the rotary cylinder drive processing unit for explaining the label die-cutting method of this embodiment. FIG. 9 is a flowchart for explaining the control flow of management information code separation and code determination for explaining the label die cutting method of this embodiment. FIG. 10 is a flowchart for explaining the control flow of the main control processing unit for explaining the label die cutting method of the present embodiment.

  In the present embodiment, since the plurality of rotary blade portions 16 are the label die cutting device 10 prepared so as to be replaceable with respect to the rotary cylinder 17, the main control processing portion 54 has the rotary blade portions attached to the rotary cylinder 17. It is necessary to know the configuration of the 16 die cutting blades 32, 33, 34, and 35.

  The main control processing unit 54 issues a command for processing indicated as “start 1” in FIG. 8A to the rotary cylinder drive processing unit 51. In the rotary cylinder drive processing unit 51, an index No. referred to as an index table. An information storage area having a finite array of three items corresponding to (number) is secured in the common memory 55. When the “start 1” process is started, the main control processing unit 54 initializes the contents of the information storage area to “0”. In addition, the index No. Is set to “0”. Index No. Is a state indicating that the rotary blade portion 16 has not been detected.

The rotary blade portion 16 of the rotary cylinder 17 is rotationally moved in units of pitch S1 by the stepping drive of the rotary cylinder driving motor 23. Therefore, this step movement amount is managed as a step address, and is added for each step (S101 to S118).
The rotary cylinder 17 goes around in 2100 steps. For this reason, the step address is handled as a change of “0 to 2099” and is processed by a motor acceleration / deceleration process (not shown) of the rotary cylinder drive processing unit 51.

  The main control processing unit 54 selects a target die cutting blade n on the rotary cylinder 17 and performs die cutting. Therefore, a command for processing “start 2” and “start 3” shown in FIG. 8B is issued to the rotary cylinder drive processing unit 51. In the “start 2” command, the rotary cylinder drive processing unit 51 sets the index number corresponding to the die cutting blade n. The start position in the index table indicated by Then, the rotary cylinder 17 is rotated by V1 acceleration and stopped to move the cutting edge of the die cutting blade n to the punching origin position (S121 to S125).

  In the “start 3” command, the rotary cylinder drive processing unit 51 accelerates and stops at the V1 speed from the punching origin position to the stop position obtained by adding the length of the mold blade corresponding to the mold punching blade n. Here, the length of the die blade corresponding to the die cutting blade n is a stop position where Wn is a value converted in step S1). Then, the label member R is punched (S131 to S135).

  Subsequently, the rotary cylinder 17 is accelerated and rotated from the stopped state to the V1 speed, and the rotation is maintained at the constant speed V1. In this state, the first index mark 37 to the fourth index mark 40 and the management information code area 25 on the rotary blade portion 16 are detected by the optical reflection type index sensor 26. When the step address reaches the start position in the index table detected first, the rotary cylinder 17 goes around, and the detection of the first index mark 37 to the fourth index mark 40 and the management information code area 25 is completed. .

  When the first index mark 37 to the fourth index mark 40 are detected, the index information of the rotary blade portion 16 is stored in the index table. At this time, each position at this point is a step address used at the time of the first detection, and indicates a temporary position.

  In addition, since the information of the TL1, TLc2, and TL2 areas are mixed in the index table, the information encoded in the management information code area 25 is separated from the information stored in the index table, and the common memory 55 is separated. To remember. Since the difference between the start positions in the index table indicates the distance of the index, the index type can be determined by calculating the difference.

For example, when the width of the management information code area 25 is 280 pitches or less, a value (275) obtained by subtracting the 5 pitch width corresponding to the 1-bit width is a determination criterion for separating the management information code area 25. . That is, as shown in FIG. 9, index lines of 275 or less from the difference information are regarded as the management information code area 25 and moved to the “management information table”.
Thereafter, the bit change of the code area is determined by comparing with the end position from the start position added by 3 pitches with the first start position in the management information table as a reference. That is, the size of the position from the start bit to the end bit is determined at intervals of 5 pitches, and it is determined that the code information “1” is continuous while the end position is large even in units of 5 pitches. Therefore, code generation is performed by shifting left while inserting “1” into the bit string. If the end position exceeds 5 pitches, “0” is inserted.

The code information is recognized as a bit string by performing the same processing from the start position of the next management information code table row. It is possible to index the definition information of the die cutting blades 32, 33, 34, and 35 encoded by extracting 8 bits from the recognized bit string. In the index table from which the information of the management information code area 25 is separated, only the information of L1 and L2 is left. Therefore, it is possible to easily determine whether the region is the L1 region or the L2 region from the difference between the start position and the end position. After discriminating between the L1 region and the L2 region, normalization sorting is performed based on the number of steps 2100 for one rotation of the rotary cylinder 17 with the L2 region as a reference.
In the index table, the L1 area is set to the first index number. Are sorted in order. That is, when there are three or more die cutting blades, there are a plurality of L2 regions, which can be distinguished by being arranged in order in the rotational direction of the rotary cylinder 17.
In this manner, in the index table, the first die extraction blade 32, the second die extraction blade 33, the third die extraction blade 34, and the fourth die extraction blade 35 are arranged in ascending order.

  After that, the mechanical distance: offset (for example, 400) from the extraction origin of the rotary cylinder 17 to the index sensor 26 is normalized and added with a round length: 2100 (S201 to S218). As a result, the starting positions of the first die extraction blade 32, the second die extraction blade 33, the third die extraction blade 34, and the fourth die extraction blade 35 of the rotary blade portion 16 on the rotary cylinder 17 are moved from the relative positions to the absolute positions. Converted to. Accordingly, it is possible to process the reference of the punching position alignment control of the label member R with the punching origin position reference.

Next, a process when the label S is punched by the label punching apparatus 10 will be described.
In the main control unit 30, the operation procedure including the rotation operation of the rotary cylinder 17, the vertical operation of the anvil roll 19, and the conveyance speed of the label member R in the label conveyance unit 14 is set by reading the management information code area 25. The The label die cutting apparatus 10 operates according to this operation procedure.

  Specifically, as shown in FIG. 10, first, in “start 1”, detection processing such as a bottom dead center position is performed while lowering the anvil roll 19 in order to initialize each part. Then, index detection on the rotary cylinder 17, index table, and management information code table creation are performed. Further, the eye mark 12 on the roll label 11 is detected, and the extraction start position of the label member R is extracted and conveyed to the origin.

  In “Start 2”, the anvil roll 19 is raised from the state prepared in “Start 1” (pressurized state). At the same time, while the roll label 11 is being conveyed, the label member R is die-cut while the rotary cylinder 17 is rotated by the punch length Wn of the die-cutting blade n. When the die-cutting of one label S is completed, the anvil roll 19 is lowered, and then the roll label 11 is conveyed in 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 to advance the selection of the same die cutting blade n. By repeating these steps sequentially, it is possible to select the die cutting blade n and perform die cutting of the label S. Thus, in this embodiment, the rotary blade part 16 is specified by the main control part 30, and the die cutting method corresponding to the configuration of the rotary blade part 16 (selection of the die cutting blade, pressure, feed speed of the label member R, etc. ) Can be used to punch the label S from the label member R.

  As described above, in the label die cutting apparatus 10 of the present embodiment, the rotary blade portion 16 has the die cutting blades 32, 33, 34, and 35 having different shapes that can be selected from a plurality of types, and the die It has a management information code area 25 for knowing information on the extraction blades 32, 33, 34, and 35. Therefore, according to the label die cutting apparatus 10 of the present embodiment, information unique to each of the plurality of types of die cutting blades 32, 33, 34, and 35 can be centrally managed using the management information code area 25. As a result, the troublesomeness and error of information management associated with the replacement of the rotary blade portion 16 are eliminated, and various settings necessary for the die cutting control can be automatically performed.

  Further, according to the label die cutting apparatus 10, the management information code area 25 can specify the number information, the height information, the length information, the width information, and the gap information of the die cutting blades 32, 33, 34, and 35. Since it is possible to do so, it is not necessary to manually input such information.

  According to the rotary blade portion 16 of the present embodiment, since it has the management information code area 25 for knowing the information of the die cutting blades 32, 33, 34, 35, the die cutting is suitably performed using a plurality of die cutting blades. Easy setting.

  According to the label die cutting method of this embodiment, information unique to a plurality of types of die cutting blades 32, 33, 34, and 35 can be centrally managed using the management information code area 25.

  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 following method can be considered as an index forming method provided on the die cutting blade.
For example, in the index formation, a portion indicating the start index of each punching blade and an index indicating the management code information area may be provided separately.
Further, although the notch method has been shown as the index forming method, a method of providing irregularities on the rotary blade portion and detecting them with a sensor (for example, a capacitance sensor) can be similarly realized.
Furthermore, the index bit string indicating the management code information area, the length, encoding, and the configuration method are merely examples, and other bit strings / lengths, encoding, and configuration methods may be used.
