Description

  The present invention relates to a continuous sheet cutting apparatus that cuts a desired label design printed on a continuous sheet along an outer shape to form a label.

  As an apparatus for cutting a large number of designs printed on a continuous sheet, for example, as shown in Patent Document 1, a roller-shaped label material on which a plurality of labels are printed is supplied to a punching forming unit and matches the design of the label. An apparatus for punching and forming a label corresponding to a design using a punching die (blade) is known.

However, in the label forming apparatus using the punching die, when the label design is transferred to a predetermined punching position, the continuous label sheet is formed after punching in a state where the transfer of the continuous label sheet is temporarily stopped. It is necessary to resume the transfer and position the next label design at the punching position, and there is a problem that the continuous label sheet is wrinkled or meandered when the continuous label sheet is stopped and restarted. Yes.

Furthermore, there is a problem that the punching die is worn due to use over time, and the label cannot be punched and formed from the continuous label sheet with high accuracy. In order to solve this problem, it is necessary to replace the punching die for every predetermined number of punches. At the time of replacement, the punching operation must be interrupted, and the label punching work efficiency is poor. Yes.

Furthermore, when a label is punched from a continuous label sheet with a punching die, paper dust is generated and attached to the punched label, and it is necessary to remove the paper dust attached in a subsequent process. May adhere to the punching die and punching device and reduce the punching accuracy, and therefore it is necessary to periodically remove the paper dust. For this reason, there is a problem that the operation efficiency of the apparatus is deteriorated and the formation efficiency of the label is deteriorated.

Also, in a label forming apparatus using a punching die, for example, a label design is printed from a continuous release sheet in which a label design is printed on the front surface and a surface base material provided with an adhesive layer on the back surface is laminated on the release base material. In the case of forming a label by pulling out, in order to integrally punch the surface base material and the release base material corresponding to the label design, the surface base material is cut with the label adhered to the release base material. The label could not be formed.

The detection roller 27 is disposed so as to be located at one end of the release sheet 1 in the direction perpendicular to the transport direction. The detection roller 27 is supported at its shaft end by a support frame 31, and a support shaft 33 is fixed to the support frame 31. The support shaft 33 is supported so as to move up and down on the main body frame 13. The The support frame 31 presses the detection roller 27 against the upper surface of the table 13a by the elastic force of an elastic member 35 such as a compression spring attached to the support shaft 33.

In addition, the said control means latches the detection signal output from a transfer detector at the timing when the said mark detector 29 detects the to-be-detected part 1e, and calculates the transfer amount of the peeling sheet 1. FIG. Then, the control means determines the drive timing of the X-axis drive motor, Y-axis drive motor, and Z-axis drive motor of the galvano scanner device 65 in the laser beam cutting means 9 to be described later based on the calculated transfer amount (transfer speed). At the same time, the driving amount of the electric motor 43 is determined.

A release sheet transfer means 11 is provided on the lower side of the table 13a in the transfer direction. The release sheet transport unit 11 includes a feed roller 39 and a pressure roller 41. An electric motor 43 such as a numerically controllable servo motor is connected to the feed roller 39, and is driven and controlled based on the transfer amount of the release sheet 1 calculated based on the detection signal from the transfer detector. .

Further, the pressing roller 41 is rotatably supported by a first arm portion of a swing arm 45 supported so as to swing on the main body frame 13. An operating member 47 such as an air cylinder or an electromagnetic solenoid attached to the main body frame 13 is connected to the other flange portion of the swing arm 45, and is a release sheet that presses against the outer peripheral surface of the feed roller 39 and passes between the two. 1 is sandwiched to enable transfer.

The take-up reel 51 is prevented from rotating on the take-up shaft 49 and can be replaced. Attached to. The take-up reel 51 has the surface base material sheet 1a attached with the label 3 formed by cutting along the outer shape of the label design 1b of the surface base material sheet 1a by the laser beam cutting means 9 described later. The peeled release base sheet 1c is wound up.

An electric motor 53 is connected to the winding shaft 49 via a powder clutch mechanism (not shown). When the tension is below a certain level, the winding shaft 49 is rotated in the winding direction while the tension is constant. When the value exceeds the value, the transmission force of the rotational force to the winding shaft 49 is changed.

Installed as possible. The scrap take-up reel 59 takes up the scrap surface base sheet 1d which is peeled from the release base sheet 1c and the label 3 is removed.

In the electric motor 55, an angle detector (not shown) is provided at the base end of the swing arm 60, and based on a signal output from the angle detector corresponding to the diameter of the scrap take-up reel 59. Then, the amount of drive of the electric motor 55 is varied to control the scrap surface base sheet 1d to be wound up.

The laser beam cutting means 9 is opposed to the table 13a with a predetermined distance to the main body frame 13 at a predetermined distance from the mark detector 29 to the lower side in the transfer direction, and the irradiation origin position is transferred. It is provided so that it may be located in the intermediate portion in the direction perpendicular to the transfer direction of the release sheet 1 to be provided. The laser beam cutting means 9 includes a laser beam oscillation device 61 that outputs laser beam, a waveguide 63 that propagates laser beam output from the laser beam oscillation device 61, and a galvano scanner device 65.

The laser light oscillation device 61 is constituted by a laser light oscillator such as a YAG laser oscillator, an excimer laser oscillator, a CO2 laser oscillator, and a fiber laser, and an optical lens (all not shown), and outputs continuous laser light. The galvano scanner device 65 includes an X-axis scan mirror attached to the X-axis drive motor, a Y-axis scan mirror attached to the Y-axis drive motor, and a condensing lens attached to the Z-axis drive motor (both shown in FIG. (Not shown) or the like.

When the continuous laser beam is output from the surface base sheet 1a along the outer shape of the label design 1b to cut and separate the label 3 as in this example, but the perforation along the outer shape of the label design 1b is formed. In this case, a pulsed laser beam is output.

The galvano scanner device 65 includes an X-axis drive motor and an X-axis drive motor based on pattern data corresponding to the outer shape of the label symbol 1b stored in advance in a storage unit (not shown) of the control unit, The X-axis scan mirror that rotates by driving and controlling the Y-axis drive motor and the Y-axis scan mirror scans the laser beam that is output from the laser beam oscillation device 61 and propagates in the two-dimensional direction of X-Y and drives the Z-axis. The motor is driven and controlled, the condenser lens is moved in the Z-axis direction, and the laser light is converged so that only the surface base sheet 1a on which the label design 1b is printed is cut by the thermal energy of the laser light.

  Next, a description will be given of the cutting operation of the label 3 by the label cutting device 5 configured as described above. First, the release sheet 1 is transferred and wound in the label cutting device 5 as follows. Taken.

  The release sheet 1 fed from the original fabric roller 15 is supported on the surface of the table 13a through the rotating roller 19a, the pressing roller 19b, and the turning guide 25, and then separated through the feeding roller 39 and the pressing roller 41. The material sheet 1c is wound around the take-up reel 51, and the surface base sheet 1a is wound around the scrap take-up reel 59. (See Figure 2)

In the above-described overhanging state, the release sheet 1 wound around the original fabric roller 15 is sandwiched between the rotating roller 19a that rotates in the transfer direction in accordance with the driving of the electric motor 23 and the pressing roller 19b that is pressed against the original. It is fed from the counter roller 15.

At this time, the release sheet 1 fed from the original fabric roller 15 is transferred in a state where a constant tension is applied by the brake mechanism 21, and the original fabric roller 15 is caused to idle due to an inertial force generated at the time of emergency stop. Prevent and keep wrinkled and prevent wrinkles.

When the tension acting on the release sheet 1 between the rotary roller 19a and the pressing roller 19b and the original fabric roller 15 becomes a predetermined value or more, the rotational driving force of the electric motor 23 to the original fabric support shaft 17 is transmitted by the brake mechanism 21. The tension applied to the release sheet 1 is controlled to be constant, and the release sheet 1 is prevented from being stretched or broken.

The release sheet 1 supported on the surface of the table 13 a from the rotating roller 19 a and the pressing roller 19 b through the turning guide 25 is sandwiched by the cooperation with the pressing roller 41 and is rotated by the driving roller 39 driven by the electric motor 43. It is transferred at a predetermined feed amount.

When the release sheet 1 is transported on the surface of the table 13a, the detection sheet 1e provided on the surface base sheet 1a of the release sheet 1 is detected by the mark detector 29 and the release sheet 1 is transported in the orthogonal direction. A signal output from a transfer detector provided on a detection roller 27 that rotates in pressure contact with the end portion is latched to calculate a transfer amount (transfer speed) of the release sheet 1, and a galvano is calculated based on the calculated transfer amount. The drive start timing (scan start timing) of the X-axis drive motor, Y-axis drive motor, and Z-axis drive motor of the scanner device 65 is determined. (See Figure 6)

That is, since the cutting start positions of the mark detector 29 and the table 13a are set at a predetermined interval, the position detection output from the transfer detector based on the mark detection signal output from the mark detector 29. The timing at which the cutting start position of the label design 1b printed on the surface base sheet 1a reaches the cutting start position is calculated by the transfer speed of the release sheet 1 calculated based on the signal.

When the cutting start position of the label design 1b is transferred to the cutting start position, the X-axis drive motor, Y-axis drive motor, and Z-axis drive motor of the galvano scanner device 65 are synchronized with the transfer of the release sheet 1 from the storage means. The laser beam that is driven and controlled based on the read pattern data and the number data of the label design 1b is scanned in the XY direction along the outer shape of the label design 1b, and the condenser lens is moved in the Z-axis direction. The laser beam is irradiated so as to converge on the surface base sheet 1a of the release sheet 1, and the label 3 is formed by cutting with the thermal energy.

At the time of irradiation with the laser beam described above, the surface base sheet 1a of the release sheet 1 is cut along the outer shape of the label design 1b, while the release base sheet 1c is kept in a cut state. The cut and formed label 3 is transferred to the lower side in the transfer direction while being stuck to the release substrate sheet 1c.

The release sheet 1 that has passed through the feed roller 39 and the pressing roller 41 is separated from the scrap surface substrate sheet 1d from which the label 3 has been extracted from the release substrate sheet 1c with the label 3 adhered to the surface. The peeled substrate sheet 1c with the label 3 attached is wound around a take-up reel 51 that is driven to rotate by an electric motor 53, and the scrap surface substrate sheet 1d is taken up around a scrap take-up reel 59. (See Figure 7)

When the tension acting on the peeling substrate sheet 1c with the label 3 taken up on the take-up reel 51 is a certain value or more, the take-up shaft 49 is driven by the clutch mechanism of the electric motor 53. The peeling of the peeling base sheet 1c is prevented by controlling the transmission of the driving force of the electric motor 53 to the above.

In this embodiment, since the release sheet 1 is transported, the laser beam is scanned in a three-dimensional direction along the outer shape of the label design 1b to cut only the surface base sheet 1a to form a label. The label 3 can be formed more efficiently than the conventional apparatus that forms the label 3 by cutting off the line.

Further, since the scanning start timing of the laser beam by the laser beam cutting means 9 is determined based on the signal from the transfer detector provided at the cutting position in the transfer direction, the laser beam is surely aligned along the outer shape of the label design 1b. The high-quality label 3 can be cut and formed.

Moreover, since the signal from the transfer detector is reset at the timing when the detected portion 1e is detected by the mark detector 29, accumulation of detection errors by the transfer detector is suppressed, and the laser beam scanning start timing is set with high positional accuracy. Can be determined.

The present invention can be modified as follows.
1. In the above description, the laser beam is output to the release sheet 1 continuously transferred to the cutting position so as to converge on the surface base sheet 1a, and the label 3 can be extracted from the surface base sheet 1a. In addition, the release substrate sheet 1c has a structure in which the label 3 is still attached to the release substrate sheet 1c, but the release substrate sheet is cut to the back surface by outputting laser light so as to converge on the release substrate sheet 1c. The label 3 may be formed in a state where 1c is integrated.

In this case, for example, an air injection member is provided on the lower side in the transfer direction of the cutting position, and compressed air is injected toward the release sheet 1 so that the release substrate sheet 1c is adhered from the release sheet 1 to the back surface. The label 3 is configured to be separated.

2. Although the said description was set as the structure which cuts the surface base material sheet 1a along the label design 1b while making a continuous sheet into the peeling sheet 1, as a continuous sheet, it is a sheet-like paper sheet, a synthetic resin sheet, Also good.

3. In the above description, the release sheet 1 is configured to output the laser beam while continuously transporting without stopping at the cutting position to form the label 3, but the continuous sheet is intermittently transported to the cutting position, The label 3 may be formed by outputting laser light to a continuous sheet stopped so that the symbol is positioned at the cutting position.

In this case, as described in 1 above, an air injection member is provided on the lower side in the transfer direction of the cutting position, and compressed air is injected toward the release sheet 1 to release the release base sheet from the release sheet 1 to the back surface. A support plate that separates the label 3 integrated with 1c, or is provided with a support plate that moves up and down and moves in the direction perpendicular to the transfer position in accordance with the design at the cutting position, and supports the label when the label is cut from the continuous sheet Is moved down and separated from the continuous sheet, and in the lowered state, it is moved in the transport orthogonal direction so that the label can be taken out.

4). In the above description, the release sheet feeding means 7 is provided with the clutch mechanism in the brake mechanism 21 and the electric motor 53 that rotates the take-up shaft 49 constituting a part of the sheet take-up means 12. Although it was set as the structure which avoids that the tension | tensile_strength more than predetermined acts on the peeling base material sheet 1c from which the material sheet 1a was isolate | separated, when setting it as a continuous sheet with high tensile strength like a synthetic resin sheet, An electric motor without a clutch may be used.

5. The above description is based on the mark detection signal output from the mark detector 29 and the galvano scanner device in the laser beam cutting means 9 by calculating the transfer speed (transfer amount) based on the position detection signal output from the transfer detector. The driving timing of the 65 X-axis driving motor, the Y-axis driving motor, and the Z-axis driving motor is determined and the driving amount of the electric motor 43 is determined, but each time a mark detection signal is output from the mark detector 29. Alternatively, the position detection signals output from the transfer detector may be counted, and the drive timing of the galvano scanner device 65 may be determined when the number of position detection signals reaches a predetermined number. In this case, the electric motor 43 is driven with a constant driving amount to continuously transfer the continuous sheet.

6). In the above description, the galvano scanner device is configured to converge the laser light on the continuous sheet by controlling the movement of the condensing lens in the Z-axis direction. As the galvano scanner device, an fθ lens is used instead of the condensing lens. A configuration may be adopted in which scanning is performed by converging laser light on a continuous sheet.
