Description

  In the present invention, a sheet material is printed while printing is performed on each printing area from a raw sheet obtained by forming a strip-shaped sheet material, which is previously divided into a plurality of areas and provided with printing areas at predetermined positions in each area, into a roll shape. The present invention relates to a sheet material transfer device that transfers the sheet material that has been fed out intermittently to a subsequent process using a region size as a transfer unit.

  Specifically, the sheet material transfer device according to the present invention is applied to a label supply device constituting a label supply portion of a label mounting device (shrink labeler) for mounting a product label such as a shrink label on a container such as a bottle. It is what is done. In this label supply device, for example, a strip-shaped film in which a number of identical designs (corresponding to labels of bottle products, hereinafter referred to as “labels”) are provided in the longitudinal direction and printed in a row is rolled. The film is fed out from the raw material formed into a film, the fed film is intermittently transferred to a film cutting device for each label portion, and the labels are cut one by one by cutting the cutting margin of the film with the film cutting device. There is something to supply.

  In this type of label supply apparatus, in order to accurately separate each label from the film, it is necessary to accurately transfer the cutting position of the film cutting margin to the cutting position of the film cutting apparatus. For this reason, the transfer device for transferring the film to the film cutting device (hereinafter referred to as “film transfer device”) has a cutting position interval D ((pattern + cutting allowance) portion set as the cutting allowance of the film. A film transfer means is provided for transferring intermittently accurately (corresponding to the distance).

  And in the film transport apparatus provided with the function of printing on each label, in consideration of the fact that the film is transported by the film transport means with the fixed distance D by the fixed dimension, the printing apparatus is provided on the upstream side of the film transport means, A configuration is known in which each label of a film is intermittently stopped at a predetermined position on the upstream side of the transfer means, and predetermined print data such as the manufacturer of the product and the expiration date is printed on the label. .

  FIG. 13 is a diagram illustrating an example of a basic configuration of a film transport apparatus having a conventional printing function.

  The sheet material transfer device 101 includes a feeding roller 103 that feeds a film F on which a number of labels are continuously printed from the original fabric 102 with a cutting margin between the original fabric 102 and the label cutting device C. The dancer roll 104 for applying tension to the film F fed by the roller 103 and the film F transferred from the feed roller 103 via the dancer roll 104 in the longitudinal direction of a certain dimension ((label + cutting allowance)). It has a configuration in which intermittent feed rollers 105 (corresponding to film transfer means) which are intermittently sent to the label cutting device C in the order of dimensions are arranged in this order. A printing device 106 is disposed in a section where the film F on the upstream side of the intermittent feed roller 105 is horizontally transferred.

  The film F intermittently fed by the intermittent feed roller 105 is separated from each label by a label cutting device C, and the separated label is received by a label delivery device (not shown) and conveyed to a process of attaching a label to a bottle in a subsequent process. However, since the shape of the separated label easily changes due to gravity, the intermittent feed roller 105 is configured to intermittently feed the film F from the top to the bottom in order to make it easy to receive each label by the label delivery device. It has become.

  The feed roller 103 is provided on the path for transferring the film F from the original fabric 102 to the intermittent feed roller 105. A drive motor excellent in position control is used as a drive source of the intermittent feed roller 105, and this kind of drive is used. Since the motor does not have enough torque to pull out the film F from the original fabric 102, before the intermittent feed roller 105 intermittently feeds the film F, the original fabric 102 is fed by a feeding roller 103 using a drive motor having excellent torque characteristics as a drive source. This is because the film F is fed out from the front.

  In addition, the dancer roll 104 is provided on the downstream side of the feeding roller 103 because the film F is transferred by the feeding roller 103 and then the film F is fed by the intermittent feeding roller 105 at a constant size. When repeating, the length of the film F in the section from the feeding roller 103 to the intermittent feed roller 105 repeatedly expands and contracts. Therefore, a constant tension is applied to the film F in the section regardless of the change in the length, and the intermittent feed roller 105. This is to stabilize the constant dimension feeding operation.

  Since the dancer roll 104 is configured to press the film F from above by its own weight, when the intermittent feed roller 103 feeds the film F at a constant size after the film F is fed by the feed roller 103, the film F is fed by the feed roller 103. Is pressed at a position Pb (hereinafter referred to as “lower limit position Pb”) when the film F is fed and at a position Pa (hereinafter referred to as “upper limit position Pa”) when the film F is fed by a fixed dimension by the intermittent feed roller 105. The pressure and the tension of the film F are balanced, and the dancer roll 104 stops at both positions Pa and Pb.

  Sensors 107 and 108 for detecting that the dancer roll 104 is displaced to both positions Pa and Pb are provided in the vicinity of the upper limit position Pa and the lower limit position Pb of the dancer roll 104, respectively. The driving of the driving motor 103 is started, and the driving of the driving motor is stopped by the detection signal of the sensor 108, whereby the film F is fed out intermittently by the feeding roller 103. That is, the dancer roll 104 also functions as an element that controls the driving of the feeding roller 103.

JP 2007-76671 A JP 2002-326746 A

  Since the film transfer apparatus 101 having the conventional printing function has a position P where each label of the film F is accurately intermittently fed in the horizontal transfer section upstream of the intermittent feed roller 105, the position P is set as the print position. The printing device 106 employs a configuration in which print data is printed in a predetermined print area in the label every time each label is sent to the print position P.

  However, in this method, as is apparent from the configuration of FIG. 13, there is no appropriate print position upstream from the horizontal transfer section in which the print position P is set, and the arrangement position of the printing device 106 is the horizontal transfer. There is a problem that it is limited to the section, obstructs the effective use of the space of the film transfer apparatus 101, and makes the handling of the printing apparatus 106 inconvenient.

  That is, the intermittent feed roller 105 is arranged so as to intermittently feed the film F from the top to the bottom, and a film cutting device 106 and a label delivery device (not shown) are arranged below the intermittent feed roller 105. The intermittent feed roller 105 is disposed at a high position in the height direction. On the other hand, since there is no restriction on the arrangement position in the height direction like the intermittent feed roller 105 from the original fabric 102 to the dancer roll 104, the film F from the original fabric 102 to the dancer roll 104 is shown in FIG. The transfer path is set at a position lower than the intermittent feed roller 105. For this reason, the transfer path of the film F from the dancer roll 104 to the intermittent feed roller 105 is a path in which the film F is once raised to a higher position of the intermittent feed roller 105 and then horizontally transferred to a position above the intermittent feed roller 105. It becomes.

  In the transfer path of the film F from the original fabric 102 to the intermittent feed roller 105, a section between the feeding roller 103 and the dancer roll 104 and a section for raising the film F on the downstream side of the dancer roll 104 to a higher position are also provided. It is difficult to dispose the printing device 106 in relation to the printing direction of the printing device 106, and it is not possible to provide a printing area in these sections. Further, in the section from the original fabric 102 to the feeding roller 103, the intermittent feeding amount of the film F by the feeding roller 103 is lower than the intermittent feeding amount of the film F by the intermittent feeding roller 105, and the printing position is set in this section. Even if the feeding roller 103 does not set the printing position of each label accurately, the printing position cannot be provided in the section of the original fabric 102 and the feeding roller 103 substantially. As a result, the arrangement position of the printing apparatus 106 is limited to a horizontal transfer section before the intermittent feed roller 105.

  Since the horizontal transfer section in front of the intermittent feed roller 105 in the film F transfer path is at the highest position, the film transfer apparatus 101 is limited when the arrangement position of the printing device 106 is limited to this horizontal transfer section. However, if the printing device 106 can be arranged in the section from the original fabric 102 to the feeding roller 103, the overall size of the film transfer device 101 can be reduced. In addition, there is a problem that the degree of freedom of design is greatly limited. In addition, since the printing device 106 is disposed at a high position of the film transfer device 101, it is extremely necessary when an operator has to directly operate the printing device 106 for maintenance or setting of printing conditions for the film F. This is inconvenient and problematic in terms of operability of the printing apparatus 106.

  The present invention has been conceived under the circumstances described above, and a printing device can be installed upstream of the feeding roller so that printing can be performed in each printing area while feeding the sheet material from the original fabric. An object is to provide a sheet material transfer device.

  According to the first aspect of the present invention, printing is performed on each print area from a raw sheet obtained by forming a strip-shaped sheet material, which is previously divided into a plurality of areas and provided with print areas at predetermined positions in each area, into a roll shape. A sheet material transfer device that unwinds the sheet material while performing the operation and intermittently transfers the unrolled sheet material with the size of the region as a transport unit, the sheet material intermittently unwinding the sheet material from the original fabric A feeding means; a fixed-size sheet material transferring means for transferring the sheet material fed by the sheet material feeding means by the size of the region; and the fixed-size sheet each time the sheet material is fed by the sheet material feeding means. Sheet material transfer control means for causing the material transfer means to perform a fixed-size transfer operation of the sheet material, the sheet material feeding means and the fixed-size sheet material transfer means by a dancer roll It is detected that the dancer roll has been displaced to a preset position by a tension applying means for applying tension to the sheet material fed out between the sheet material and a fixed-size feed of the sheet material by the fixed-size sheet material transfer means. Displacement detecting means for detecting, and mark detecting means for detecting a predetermined mark set in advance corresponding to each print area of the sheet material on the sheet material feeding path from the original fabric to the sheet feeding means, Printing is performed on the sheet material on the feeding path, and when the printing process is completed, a printing unit that outputs printing completion information, and the sheet material at a predetermined timing based on the detection of the mark by the mark detection unit. When the displacement of the dancer roll is detected by the print control means for starting the printing process in the print area corresponding to the mark and the displacement detection means, The sheet material feeding means starts the sheet material feeding operation, and stops the feeding operation based on the print completion information output from the printing means, whereby the sheet material feeding means performs the sheet material feeding operation. A sheet material transfer device comprising: a feeding control unit that performs intermittently.

  2. The sheet material transfer apparatus according to claim 1, wherein the feeding control means outputs a preset number of the print completion information from the printing means after the sheet material feeding means starts the feeding operation of the sheet material. Then, it is preferable to stop the feeding operation of the sheet material feeding means based on the print completion information output last.

  The sheet material transfer device according to claim 1 or 2, wherein a label having the same pattern is formed in the plurality of regions, and each label is generated by cutting each region. The mark may be set for a specific figure or pattern included in the symbol.

  The sheet material transfer apparatus according to any one of claims 1 to 3, wherein the sheet material is formed of a film, and the printing unit prints by irradiating a laser to thermally melt the surface layer of the film. It is good that it is a laser marker which performs.

  According to the sheet material transfer device of the present invention, the sheet material divided into a plurality of regions from the original fabric is intermittently fed by the sheet material feeding means, and the sheet material feeding operation of the sheet feeding means is stopped. In addition, the sheet transfer operation in which the fed sheet material is transferred by the fixed-size sheet material transfer means by the size of the region is repeated.

  In the sheet transfer operation, the position of the dancer roll is changed in accordance with the constant-size feeding of the sheet material, and the dancer roll is displaced to a preset position by the displacement detection means. Is detected, the feeding operation of the sheet material feeding means is started. When a mark set on the sheet material is detected by the mark detection means during a period when the sheet material is being fed from the original by the sheet material feeding means, the sheet is printed by the printing means at a predetermined timing based on the detection. When printing is performed in the printing area of the material and printing completion information indicating that the printing process is completed is output from the printing unit, the feeding operation of the sheet material feeding unit is stopped.

  The sheet material transfer device according to the present invention sets a mark corresponding to each printing area on a sheet material divided into a plurality of areas and in which a printing area is formed, and feeds the sheet material from the original fabric. Since the mark is detected and the printing start timing of the printing apparatus is controlled during the printing period, the printing apparatus can be disposed between the original fabric and the sheet material feeding means.

  Thereby, it is not necessary to dispose the printing means at a high position of the sheet material transfer device as in the conventional case, and the size of the sheet material transfer device in the height direction can be shortened and the entire device can be made compact. In addition, since the printing means can be installed at a low position in the sheet material transfer device, the operability is hindered when the operator must operate the printing means directly for maintenance or setting of printing conditions for the sheet material. There is no.

  Further, since the feeding operation of the sheet material feeding means is stopped using the printing completion information of the printing apparatus, it is not necessary to detect the displacement position of the dancer roll for stopping the feeding operation of the sheet material feeding means as in the prior art. Thus, the number of sensors for detecting the displacement position of the dancer roll can be reduced.

  FIG. 1 is a diagram showing a basic configuration of a sheet material transfer device according to the present invention. FIG. 2 is a block diagram illustrating an electrical configuration of the sheet material transfer device. In FIG. 2, the same members as those shown in FIG.

  The sheet material transfer device 1 is a strip-shaped sheet material F in which a large number of symbols (corresponding to product labels) mounted on the surface of a container such as a bottle are printed in a line with a constant interval (corresponding to a cutting margin). The sheet material is fed once from the original fabric 2 by the feeding roller 3 and then the fed film F is fed by the intermittent feeding roller 5 by a certain dimension (the dimension of the (design + cutting allowance) portion). It is a device that intermittently feeds F to the label cutting device C.

  The film F intermittently fed by the sheet material transfer device 1 is cut by a label cutting device C, and the cut portion (label portion) is received by a label delivery device (not shown) and delivered to a label sticking device (not shown). And is stuck on the surface of the container by the label sticking device.

  The sheet material transfer device 1 includes a feeding roller 3 that intermittently feeds the sheet material F from the original fabric 2 between the original fabric 2 that forms the belt-shaped sheet material F in a roll shape and the label cutting device C, and a feeding roller. 3, the length of the dancer roll 4 for applying tension to the sheet material F fed by 3 and the sheet material F transferred from the feed roller 3 via the dancer roll 4 in a longitudinal direction ((pattern + cutting allowance)). 3 (see dimension d1 in FIG. 3), and intermittent feed roller 5 that intermittently feeds to label cutting device C in this order. Further, a mark sensor 8 and a printing device 6 are arranged in this order in a section from the raw fabric 2 to the feeding roller 3.

  The sheet material F is, for example, a heat-shrinkable strip-like film (shrink film) printed with a large number of product label symbols G in a row as shown in FIG. The symbol G includes a trademark, an image for product advertisement, and the like. The sheet material F (hereinafter referred to as “film F”) has a region La in which the pattern G is printed in the longitudinal direction and a region Lb corresponding to the cutting allowance.

  The pattern G is printed almost at the center of the region La. Both sides along the longitudinal direction of the region La are film base portions, and the print region Lc is substantially at the center of one film base portion (the lower film base portion in FIG. 3 is a transparent or translucent portion). Is provided. Each printing area Lc is an area where predetermined printing data relating to the bottle product such as the date of manufacture and the expiration date of the product is printed by the printing device 6. It should be noted that the print data relating to the bottle product is not limited to the above, and it goes without saying that appropriate items are included depending on the type and nature of the bottle product.

  The film F intermittently sent to the label cutting device C is cut from the sheet material transfer device 1 (hereinafter referred to as “film transfer device 1”) so as to be cut at the center of the cutting allowance (region Lb). Since it is intermittently sent to the apparatus C, the center of each region Lb is the cutting position CL. Accordingly, the interval d1 (same as the dimension in the longitudinal direction of (region La + region Lb)) of the cutting position CL is the fixed dimension of the film F that is intermittently fed by the intermittent feeding roller 5.

  A rectangular mark M is printed at the cutting position CL on one side (the lower side in FIG. 3) of each region Lb. The mark M is for acquiring a print timing for causing the printing device 6 to print print data for a print region Lc adjacent to the upstream side of the mark M during the feeding of the film F. The mark M is detected by the mark sensor 8, and the mark detection signal is used as printing timing by the control device 10. Control of printing timing by the mark M will be described later.

  The basic configuration for intermittently feeding the film F of the sheet material transfer device 1 is the same as the basic configuration for intermittently feeding the film F of the conventional sheet material transfer device 101 shown in FIG. Accordingly, the original fabric 2, the feeding roller 3, the dancer roll 4 and the intermittent feed roller 5 of the sheet material transfer device 1 are respectively connected to the original fabric 102, the supply roller 103, the dancer roll 104 and the intermittent feed roller 105 of the sheet material transfer device 101. It corresponds. Further, the transfer path of the film F of the sheet material transfer apparatus 1 is substantially the same as the transfer path of the film F of the sheet material transfer apparatus 101 shown in FIG.

  In FIG. 1, the plurality of rollers 9 are guide members that guide the film F in order to transfer the film F along the transfer path. The plurality of rollers 9 are disposed at locations necessary for changing the transport direction of the film F.

  The roles and operations of the respective elements such as the original fabric 2 and the feeding roller 3 of the sheet material transferring apparatus 1 are the same as those described for the respective elements such as the original fabric 102 and the supplying roller 103 of the sheet material transferring apparatus 101 in FIG. Therefore, the description which overlaps here is abbreviate | omitted and demonstrates the structure of each element.

  The feeding roller 3 includes a driving roller 3A and a driven roller 3B whose circumferential surfaces are pressed against each other, and a film F is sandwiched between the driving roller 3A and the driven roller 3B. A feed motor 3C, which is a drive source, is connected to the drive roller 3A. For example, a DC motor that is excellent in torque characteristics and suitable for feeding the film F from the raw fabric 2 is used as the feeding motor 3C. As shown in FIG. 2, the driving of the feeding motor 3 </ b> C is performed by a driving circuit 3 </ b> D, and the control device 10 controls the rotation start and rotation stop of the feeding motor 3 </ b> C by the driving circuit 3 </ b> D.

  The control device 10 is a device that comprehensively controls the feeding process of the film F, the printing process on the film F that is being fed, and the fixed-size feeding process after the feeding of the film F. is there. As the control device 10, a microcomputer including a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory) is used. An operation display device 11 for an operator to input various information (for example, intermittent feeding period T and print data) to the control device 10 and to display the state of the film transfer operation. Is connected. As the operation display device 11, a liquid crystal display or a touch panel is used, but a CRT display may be used.

  When a drive start signal is input from the control device 10, the drive circuit 3D supplies a drive voltage to the feed motor 3C, and when a drive stop signal is input from the control device 10, the drive circuit 3D supplies the drive voltage to the feed motor 3C. Stop. The feeding motor 3C starts rotating when the driving voltage is supplied from the driving circuit 3D, and stops rotating when the supply of the driving voltage from the driving circuit 3D is stopped. When the feeding motor 3C rotates, the rotational force is transmitted to the driving roller 3A, and the driving roller 3A rotates counterclockwise in FIG. The driven roller 3B is rotated in the clockwise direction in FIG. 1 by the rotation of the driving roller 3A, and the film F is fed from the original fabric 2 to the dancer roll 4 side by the rotation of both rollers 3A and 3B.

  The dancer roll 4 applies a certain tension to the film F between the feeding roller 3 and the intermittent feeding roller 5 by being placed as a weight on the upper side of the film F fed by the feeding roller 3. The dancer roll 4 is fixed to the tip of an arm 4A that is rotatably supported by the shaft 4B, and swings about the shaft 4B as a fulcrum.

  When the film F is intermittently fed by the feeding roller 3, the dancer roll 4 moves downward to the lower limit position Pb that absorbs the slackness of the film F caused by the feeding amount. On the other hand, when the fed film F is intermittently fed by the fixed feeding roller 5 by the constant feeding distance d1 after the feeding of the film F by the feeding roller 3, the dancer roll 4 is shortened as the length of the film F becomes shorter. Rises and stops at the upper limit position Pa. Thereafter, the dancer roll 4 moves up and down between the lower limit position Pb and the upper limit position Pa as the film F feeding operation by the feeding roller 3 and the fixed dimension feeding by the intermittent feeding roller 5 are alternately repeated.

  In the conventional film transport apparatus 101 shown in FIG. 13, the dancer roll 104 detects that the dancer roll 104 has been displaced to the upper limit position Pa and the lower limit position Pb, and controls the start and stop of the feeding operation of the feeding roller 103. However, the dancer roll 4 according to this embodiment functions as an element that detects that the dancer roll 4 is displaced to the upper limit position Pa and controls only the start of the feeding operation of the feeding roller 103. To do. Therefore, the dancer sensor 7 corresponding to the sensor 107 is provided at a position close to the upper limit position Pa. The stopping of the feeding operation of the feeding roller 103 is controlled by the printing device 6 as will be described later.

  For the dancer sensor 7, for example, a reflective photosensor is used. The dancer sensor 7 projects light toward the upper limit position Pa. When the dancer roll 4 rises to the upper limit position Pa and reflects light from the dancer sensor 7 and receives the reflected light, the dancer roll 4 rises to the raised position Pa. Is output to the control device 10. When the displacement detection signal is input from the dancer sensor 7, the control device 10 outputs a drive start signal to the drive circuit 3D. The dancer sensor 7 may be another optical sensor such as a transmissive photosensor or a separate photosensor, or a mechanical switch. Further, as the dancer sensor 7, for example, an inductive proximity switch that detects a metal that is a detection body with a sensor that uses electromagnetic induction may be used.

  Similarly to the feeding roller 3, the intermittent feeding roller 5 is composed of a driving roller 5A and a driven roller 5B whose circumferential surfaces are pressed against each other, and a film F is sandwiched between the driving roller 5A and the driven roller 5B. An intermittent feed motor 5C as a drive source is connected to the drive roller 5A. As the intermittent feed motor 5C, for example, a stepping motor that is excellent in position control and suitable for fixed-size feed is used. The intermittent feed motor 5C is driven by a drive circuit 5D and the control device 10 as shown in FIG.

  The control device 10 outputs a command signal for intermittent feeding of the film F to the drive circuit 5D at a preset period T. Information on the number of pulses corresponding to the amount of rotation of the stepping motor necessary for feeding the film F by the dimension d1 is preset in the drive circuit 5D from the control device 10. When an intermittent feed command signal is input from the control device 10, the drive circuit 5D outputs drive pulses corresponding to the number of pulses to the intermittent feed motor 5C. As a result, the intermittent feed motor 5C rotates by a predetermined rotation amount.

  Note that the dimension d1 is input from the operation display device 11 to the control device 10 by the operator each time a different original fabric 2 is set because the size of the pattern G is different when the type of the film F is different. Therefore, every time the fixed feed constant dimension d1 is changed, the control device 10 sets the information in the drive circuit 5D.

  When the intermittent feed motor 5C rotates, the rotational force is transmitted to the intermittent feed roller 5A, and the intermittent feed roller 5A rotates counterclockwise in FIG. The driven roller 5B is rotated clockwise in FIG. 1 by the rotation of the driving roller 5A, and the film F is sent to the label cutting device C by the dimension d1 by the rotation of both the rollers 5A and 5B.

  The printing device 6 is a device that prints print data on the surface of the film F. A laser marker is used for the printing device 6. The reason why the laser marker is used for the printing device 6 is that printing can be performed on the film F in a non-contact manner, and that the film F is a heat-shrinkable resin film, so that heating printing with a laser is suitable. The printing device 6 is installed at a position above the feeding path of the film F between the original fabric 2 and the feeding roller 3 by a predetermined distance.

The printing device 6 prints print data on the film F by irradiating, for example, a CO ₂ laser with a wavelength of 10.6 μm toward the film F from the laser emission port 6a and melting the film surface to form irregularities. . The type of laser is not limited to the CO ₂ laser, but may be a YAG laser or a YVO ₄ laser.

  The printing device 6 is not limited to the laser marker. A printing apparatus of a printing method suitable for the material of the film F can be selected as appropriate. For example, when the material of the film F is paper, an ink jet printer can be used.

  A control device 10 is connected to the printing device 6, and the printing timing of the printing device 6 is controlled by the control device 10. That is, the control device 10 outputs a printing start signal to the printing device 6, and the printing device 6 receives the printing start signal and irradiates the film F with laser light modulated by the printing data from the laser emission port 6a. The control device 10 receives a mark detection signal from the mark sensor 8 and outputs a print start signal to the printing device 6. Accordingly, the printing apparatus 10 substantially starts printing on the film F in response to the mark detection signal from the mark sensor 8.

  When the printing process on the film F is completed, the printing device 6 outputs a printing completion signal to the control device 10. In response to the print completion signal from the printing device 6, the control device 10 outputs a drive stop signal to the drive circuit 3 </ b> D of the feed motor 3 </ b> C, and stops the feed operation of the feed roller 3. That is, the printing device 6 and the control device 10 function as elements that control the driving stop of the feeding roller 3.

  As described above, the feed start of the feed roller 5 is controlled by the displacement detection signal to the upper limit position Pa of the dancer roll 4 by the dancer sensor 7, and the feed stop of the feed roller 5 is controlled by the print completion signal of the printing device 6. The feeding amount of the film F fed by the feeding roller 5 is not as accurate as the feeding amount of the film F by the intermittent feeding roller 3, but the feeding amount is approximately the size of one label (a value close to the fixed dimension d1). It has become.

  The mark sensor 8 detects the mark M formed on the film F while the film F is being fed. For the mark sensor 8, for example, a reflective photosensor is used. The mark sensor 8 projects light toward the film 8 and outputs a pulsed mark detection signal (see FIG. 4) in which the amount of reflected light received is shaped to a binary level.

  The mark sensor 8 has a printing area on the upstream side of the printing device 6 in which the distance between the laser emission port 6a of the printing device 6 and the projection port 8a of the mark sensor 8 is adjacent to the right end of the mark M and the downstream side of the mark M. It is arranged so as to be a distance from the right end of Lc (see the distance d2 between the right end p1 of the mark M and the right end p2 of the print area Lc in FIG. 3).

  FIG. 4 shows the waveform of the mark detection signal when the mark sensor 8 scans the front and rear of the mark M relative to the feeding direction of the film F (see the scan line N in FIG. 3). In the figure, the fall timing of the mark detection signal corresponds to the position p1 where the scan line N and the right end of the mark M intersect in FIG. 3, and the rise timing is the position where the scan line N and the left end of the mark M intersect (cutting). Corresponding to the position CL).

  A control device 10 is connected to the mark sensor 8, and a mark detection signal from the mark sensor 8 is input to the control device 10. The control device 10 detects the falling timing of the mark detection signal and outputs a printing start signal to the printing device 6 at the detection timing.

  The control device 10 may detect the falling timing of the mark detection signal and output a printing start signal to the printing device 6 at the detection timing. Further, the waveform of the mark detection signal output from the mark sensor 8 is not limited to the waveform shown in FIG. 4, and may be a waveform in which the high level and the low level are reversed with respect to the waveform. In this case, the control device 10 outputs a printing start signal to the printing device 6 at the rising timing or falling timing of the mark detection signal. Further, the mark sensor 8 is not limited to the reflection type photosensor, and other optical sensors such as a transmission type photosensor or a separation type photosensor may be used. Further, an RGB color sensor may be used as the mark sensor 8.

  FIG. 5 is a diagram showing a relative positional relationship of the film F with respect to the printing device 6 and the mark sensor 8 at the start and end of the feeding of the film F. (A) is a positional relationship at the start of feeding of the film F, and (b) is a positional relationship at the end of feeding of the film F.

  As described above, the printing device 6 outputs a printing completion signal to the control device 10 when the printing process of the printing data in the printing area Lc is completed, and the control device 10 receives the printing completion signal and receives the printing completion signal. The feeding operation of F is stopped. FIG. 5A shows a case where the print data is printed on substantially the entire print area Lc of the nth label. In this case, a printing completion signal is output from the printing device 6 to the control device 6 at a timing when the laser optical axis of the printing device 6 reaches the end p3 of the nth printing region Lc (the left end of the printing region Lc in FIG. 5). Since the feeding operation of the film F is stopped almost at the timing, the relative positional relationship of the film F with respect to the printing device 6 and the mark sensor 8 at the start of feeding the (n + 1) th label is shown in FIG. As shown.

  When the feeding operation of the film F is performed from the state of FIG. 5A, the film F is scanned by the mark sensor 8 by the feeding operation, and the mark sensor 8 is (n + 1) as shown in FIG. The level of the mark detection signal of the mark sensor 8 falls when the right edge of the mark M formed between the (th) and (n + 2) th sheets is reached.

  Since the control device 10 outputs a print start signal to the printing device 6 at the timing when the level of the mark detection signal from the mark sensor 8 falls, the printing device 6 receives the print start signal and receives the print data on the film F. Start printing. The distance between the light projection port 8a of the mark sensor 8 and the laser emission port 6a of the printing apparatus 6 is adjusted to the distance d2 between the right end p1 of the mark M and the right end p2 of the print region Lc adjacent to the downstream side of the mark M. At the timing when the print start signal is output from the control device 10 to the printing device 6, as shown in FIG. 5B, the laser optical axis of the printing device 6 is at the right end P2 of the (n + 2) th printing area Lc. It is in.

  Therefore, the printing device 6 starts laser irradiation at the timing when the right end P2 of the (n + 2) th printing area Lc faces the laser emission port 6a with respect to the film F being fed, and the (n + 2) th sheet Print data is accurately printed in the print area Lc. Then, when the left end p3 of the (n + 2) th printing area Lc reaches a position facing the laser emission port 6a, the printing process is completed, and the feeding operation of the film F is stopped at that timing. The relative positional relationship of the film F with respect to the printing device 6 and the mark sensor 8 at this time is as follows. In FIG. 5A, the number of each symbol G of the (n−1) th to (n + 1) th sheets is one. This is the positional relationship when the pattern is changed to the n-th to (n + 2) -th symbol G that has been moved up one by one.

  In the present embodiment, the distance between the light projection port 8a of the mark sensor 8 and the laser emission port 6a of the printing device 6 is the distance between the right end p1 of the mark M and the right end p2 of the print region Lc adjacent to the downstream side of the mark M. Although the distance is adjusted to d2, the distance between the mark sensor 8 and the printing device 6 can be arbitrarily adjusted between the distance d2 and the distance d1. When the interval d2 is adjusted, there is an advantage that the detection timing of the mark M can be set as the print timing of the print data.

  When the distance is adjusted to an arbitrary distance d3 between the distance d2 and the distance d1, as shown in FIG. 6, when the film F is fed out by the difference Δd between the distance d3 and the distance d2 from the detection timing of the mark M, the mark Since the left end p3 of the printing area Lc adjacent to the downstream side of M is a position facing the laser emission port 6a, printing is performed from the control device 10 to the printing device 6 with a delay Δt from the detection timing of the mark M. A start signal may be output. The delay time Δt is Δt = Δd / v2 = (d3−d2) / v2 where the feeding speed of the film F by the feeding roller 3 is v2.

  Next, the intermittent feed control of the film F by the control device 10 will be described using the time chart shown in FIG. 7 and the flowchart shown in FIG.

  FIG. 7 is a time chart showing an intermittent feeding sequence of the film F by the film transfer apparatus 1. In the figure, (a) shows an intermittent feed command signal output from the control device 10 to the drive circuit 5D of the intermittent feed motor 5. (B) shows a change in the feeding speed of the film F by the intermittent feeding roller 5. (C) shows a change in the position of the dancer roll 4. (D) shows a displacement detection signal output from the dancer sensor 7 to the control device 10. (E) shows the change in the feeding speed of the film F by the feeding roller 3. (F) indicates a mark detection signal output from the mark sensor 8 to the control device 10. (G) shows a printing process period of the printing device 6 and a printing completion signal output from the printing device 6 to the control measure 10. (H) indicates a drive stop signal output from the control measure 10 to the drive circuit 3D of the feeding motor 3.

  In (b) and (e), the inclined part is an accelerated or decelerated part. Since the acceleration section and the deceleration section of the feeding roller 3 and the intermittent feed roller 5 are very short compared to the constant speed section, in the following description, the driving section of the feeding roller 3 and the intermittent feed roller 5 will be described as a constant speed section.

  FIG. 8 is a flowchart showing a processing procedure for intermittent feeding control of the film F of the control device 10. FIG. 7 shows the case where the film F intermittently feeds two labels, but in the following description, the nth and (n + 1) th labels are intermittently fed with reference to FIGS. 5 and 7. This will be described as an example.

  As shown in FIG. 7A, the control device 10 outputs an intermittent feed command signal S1 to the drive circuit 5D at a cycle T. Immediately before the control device 10 outputs the command signal S1 at the timing t1, the film F is stopped with respect to the printing device 6 and the mark sensor 8 in the positional relationship of FIG. At this time, since the film F is fed by the feeding roller 3 for one label (approximately the dimension d1), the dancer roll 4 is stopped at the lower limit position Pb.

  When the control device 10 outputs the command signal S1 to the drive circuit 5D at the timing t1 (# 1), the intermittent feed roller 5 starts to be driven (# 2). The intermittent feed roller 5 stops at the timing t2 when the film F is fed by the dimension d1 (m) at the speed v1 (m / min). If the time from t1 to t2 is T1, T1 = d1 / v1, so the film feed speed v1 of the intermittent feed roller 5 is set to d1 / T1.

  When the film F is fed by the intermittent feeding roller 5, the length of the film F between the feeding roller 3 and the intermittent feeding roller 5 is shortened, and accordingly, the dancer roll 4 rises and reaches the upper limit position Pa. Then, the displacement detection signal S2 is input from the dancer sensor 7 to the control device 10 (# 3: YES). Since the dancer roll 4 reaches the upper limit position Pa when the film F is fed by a constant dimension d1 by the intermittent feed roller 5, the displacement detection signal S2 is input from the dancer sensor 7 to the control device 10 at a timing of approximately t2.

  The control device 10 receives the displacement detection signal S2 from the dancer sensor 7 and outputs a drive start signal S5 to the drive circuit 3D of the feed roller 3 (# 4). When the control device 10 outputs the drive start signal S5 to the drive circuit 3D at the timing t2, the drive of the feeding roller 3 is started (# 5). The feeding roller 5 feeds the film F at a speed v2 (m / min) (v2 <v1).

  When the mark sensor 8 scans the mark M between the n-th symbol G and the (n + 1) -th symbol G by feeding the film F, a mark detection signal S3 is output from the mark sensor 8 to the control device 10 ( # 6: YES). When the mark detection signal S3 is input, the control device 10 outputs a print start signal to the printing device 6 at the falling timing of the mark detection signal S3 (# 7). The printing device 6 receives the printing start signal from the control device 10 and starts printing the printing data (# 8).

  Assuming that the fall timing of the mark detection signal S3 is t3, the positional relationship of the film F with respect to the printing device 6 and the mark sensor 8 is the positional relationship of FIG. 5B at the timing of t3. Accordingly, when the printing device 6 starts printing the print data at the timing t3, the print data is printed from the right end p2 to the left end p3 of the (n + 1) th print area Lc by the feeding of the film F.

  When the printing process is completed at timing t4 when the laser optical axis of the printing apparatus 6 reaches the left end p3 of the (n + 1) th printing area Lc, the printing completion signal S4 is output from the printing apparatus 6 to the printing control apparatus 10. The When the print completion signal S4 is input (# 9: YES), the control device 10 outputs a drive stop signal S6 to the drive circuit 3D (# 10). The drive circuit 3D receives the drive stop signal S6 from the control device 10 to stop the driving of the feeding roller 3, and the film F stops at the timing t5 when the feeding roller 3 stops. And it waits until the period T passes from the timing of t1 (until the timing of t6), and when the period T passes (# 11: YES), it returns to step # 1.

  When the feeding of the film F is started at the timing t2, the length of the film F between the feeding roller 3 and the intermittent feeding roller 5 is increased by the feeding operation, and the dancer roll 4 is lowered accordingly. At the timing t5 when the feeding roller 3 stops the feeding operation, the film F is fed substantially by one label, the dancer roll 4 is displaced to the lower limit position Pb, and this state is t6 when the next intermittent feeding operation is started. Continue until timing.

  Then, the same intermittent feed operation is performed for the (n + 2) th label from the timing t6. That is, the timings t6 to t9 correspond to the timings t1 to t5, respectively, and the operations at the respective timings t1 to t5 described above are performed.

  In the above embodiment, the standby period T3 is provided at the rear end of the cycle T. However, this standby period T3 is not necessarily required and may be omitted. When the waiting period T3 is not provided, the intermittent feeding period of the film F by the intermittent feeding roller 5 is (T1 + T2), the feeding period of the film F by the feeding roller 2 is (T2 + T1), and the both periods are the same. That is, the film F feeding operation and the fixed-size feeding operation are alternately performed at the same period T.

  In the above embodiment, the mark M is printed on the film F separately from the design G. However, a specific figure or pattern in the design G may be used as the mark M. For example, as shown in FIG. 9, when the pattern G includes a rectangular pattern g1 and a circular pattern g2, the rectangular pattern g1 that the edge portion has is set as the mark M, and the edge portion (for example, the rectangular pattern g1) The detection signal of the left and right sides of the frame) can be used as the mark detection signal S3. Further, the formation position of the mark M is not limited to the area Lb, and can be set to an appropriate position in the area La as long as the print timing described above can be acquired.

  As described above, according to the sheet transfer apparatus 1 according to the present embodiment, the mark M is set on the film F corresponding to each label, the mark M is detected during the period during which the film F is being sent, and the mark Since the printing device 6 causes printing data to be printed in the printing region Lc of each label based on the detection signal S3, the printing device 6 is disposed between the original fabric 2 and the feeding roller 3, and the film F formed by the feeding roller 3 is used. The printing process can be performed during the feeding period.

  Therefore, unlike the conventional sheet material transfer device 101, it is not necessary to arrange the printing device 6 at a high position of the sheet material transfer device 1, and the size of the sheet material transfer device 1 in the height direction can be shortened or the entire device can be reduced. Can be made compact.

  Further, since the printing device 6 can be installed at a low position of the sheet material transfer device 1, the operability can be improved even when the operator has to operate the printing device 6 for maintenance or setting of printing conditions on the sheet material. There is no hindrance.

  Further, since the feeding operation of the feeding roller 3 is stopped using the printing completion signal S4 of the printing device 6, the lower limit of the dancer roll 4 for stopping the feeding operation of the feeding roller 3 as in the conventional sheet material transfer device 101. There is no need to detect the position Pb, and accordingly, the dancer sensor for detecting the displacement position of the dancer roll 4 can be reduced.

  By the way, in embodiment mentioned above (henceforth "1st Embodiment"), after film | membrane F is fed out for the dimension of one label, only the dimension d1 of one label is correctly sent with respect to the amount of the fed out. However, the feeding amount of the film F is not limited to one label, and a plurality of labels may be fed out. For example, as shown in FIG. 10, during the period in which the intermittent feeding roller 5 intermittently feeds the film F by a fixed size by two labels, the feeding roller 3 feeds the film F by two labels and during the feeding. The printing device 6 may perform printing processing for two labels (hereinafter, this embodiment is referred to as “second embodiment”).

  FIG. 10 is a time chart corresponding to FIG. 7, but the position of the dancer roll 4 in (C) is omitted.

  In the second embodiment, as shown in FIG. 10 (a), the control device 10 outputs an intermittent feed command signal S1 to the drive circuit 5D in a cycle T, so that the intermittent feed roller 5 is subjected to every cycle T. The film F is sent to the label cutting device C by a fixed dimension d1. When the fixed-size feed of the nth label is performed at the timing t1, the dancer roll 4 rises to the upper limit position Pa, and when the displacement detection signal S2 is input from the dancer sensor 7 to the control device 10 at the timing t2. Since the driving start signal S5 is input from the control device 10 to the driving circuit 3D, the feeding roller 3 starts the feeding operation of the film F.

  When the feeding operation of the film F is started, the mark detection signal S3 for the (n + 1) th label is output from the mark sensor 8 at the timing of t3, and the printing area 6 of the (n + 1) th label is printed by the printing device 6. However, the print completion signal S4 output from the printer 6 when the printing process is completed is ignored by the controller 10, and the drive stop signal S6 is not output from the controller 10 to the drive circuit 3D. .

  That is, for example, when the feeding operation of the film F is started, the control device 10 counts the mark detection signal input from the mark detection signal S3 thereafter, and if the count value is “2”, the control device 10 causes the drive circuit 3D to count. A drive stop signal S6 is output.

  For this reason, since the feeding roller 3 continues the feeding operation of the film F, the mark detection signal S3 for the (n + 2) th label is output from the mark sensor 8 at the timing ta, and the printing device 6 outputs the (n + 2) th sheet. The print data is also printed in the label print area Lc. The control device 10 receives a print completion signal S4 output from the printing device 6 when the printing process is completed, and outputs a drive stop signal S6 to the drive circuit 3D. As a result, the feeding roller 3 stops the feeding operation of the film F at the timing tb when the drive stop signal S6 is output from the control device 10. That is, the feeding roller 3 performs the feeding operation of the film F for two labels every time a period twice as long as the period T elapses.

  In the second embodiment, the cycle of the feeding operation of the feeding roller 3 is twice as long as the constant-size feeding cycle T of the intermittent feeding roller 5, and the feeding speed of the film F is further increased compared to the first embodiment shown in FIG. Since it can be delayed, the film F can be fed out without causing any trouble in the printing process by the printing device 6 even if the intermittent feed roller 5 is shortened and the intermittent feed period T is shortened to increase the speed of the intermittent feed. There are advantages that can be made.

  In the first and second embodiments, the printing process by the printing device 6 is performed while the film F is being fed. However, when the marker detection signal S3 is output from the marker sensor 8 to the control device 10, the control device 10 The driving stop signal S6 is output from the driving circuit 3D to stop the feeding operation of the film F by the feeding roller 3, and then a printing start signal is output from the control device 10 to the printing device 6 so that the film F is stopped. The print data may be printed.

  This method is a method of performing printing processing by the printing device 6 after the feeding operation of the film F by the feeding roller 3 is stopped (hereinafter, this method is referred to as “printing method while the film is stopped”). In this method, when the feeding operation of the film F by the feeding roller 3 is stopped, the laser optical axis of the printing device 6 needs to be positioned at the right end p2 of the printing region Lc as shown in FIG. 5B. is there. Since the film F is stopped, the printing device 6 prints the print data in the print area Lc by swinging the laser optical axis from the right end p2 to the left end p3 of the print area Lc.

  FIG. 11 is a time chart when printing data is printed during the stop period after the film F is fed (hereinafter, this embodiment is referred to as “third embodiment”). The time chart of FIG. 11 corresponds to the time church of FIG. 7, but the contents of (f), (g), and (h) are different from those of FIG.

  In the third embodiment, when a displacement detection signal is output from the dancer sensor 7 at the timing t2, the feeding operation of the film F by the feeding roller 3 is started. The feeding operation is performed from the mark sensor 8 at the timing t3. When the mark detection signal S3 is output, it is stopped. In the first embodiment shown in FIG. 7, when the mark detection signal S3 is output, a print start signal is output from the control device 10 to the printing device 6. In the third embodiment shown in FIG. 11, the mark detection signal is output. When S3 is output, a driving stop signal S6 is output from the control device 10 to the driving circuit 3D, and the feeding operation of the feeding roller 3 is stopped.

  In the third embodiment, the feeding amount of the film F by the feeding roller 3 is approximately the size of one label (dimension of d2), and the film F with respect to the printing device 6 and the mark sensor 8 when the feeding of the film F is stopped. Since the positional relationship must be such that the laser optical axis of the printing device 6 is positioned at the right end p2 of the printing region Lc (see the positional relationship in FIG. 5B), printing at the start of feeding of the film F is performed. The relative positional relationship of the film F with respect to the apparatus 6 and the mark sensor 8 is the positional relationship shown in FIG.

  When the film F is fed out by the feeding roller 3 from the state shown in FIG. 12, the mark sensor 8 scans the mark M adjacent to the upstream side of the (n + 1) -th symbol G, so that the right end p1 of the mark M is detected. The feeding operation of the film F by the feeding roller 3 is stopped at the timing when the mark detection signal S3 to be detected is output. Therefore, if print data is printed by the printer 6 while the film F is stopped, the print data is printed in the print area Lc corresponding to the (n + 1) th symbol G.

  In the third embodiment, since the feeding operation of the feeding roller 3 is stopped by the detection signal of the mark M, it is not possible to accurately stop the laser optical axis of the printing device 6 at a position where it coincides with the right end p2 of the printing area Lc. difficult. However, since the feeding operation of the film F is stopped using the detection signal of the mark M set on the film F, the feeding operation of the film F is performed using the displacement detection signal in which the conventional dancer roll 4 is displaced to the lower limit position pb. Since the accuracy of the stop position of the film F with respect to the printing device 6 is better than the method of stopping, there is no problem in the print quality even if the print start position of the print region Lc changes minutely within the accuracy range. There is no inconvenience even if the printing method while the film is stopped is applied.

  In the third embodiment, as shown in FIG. 11, it is necessary to provide a period for performing the printing process after the film F is stopped until the fixed-size feeding of the film F by the intermittent feeding roller 5 is started. Since the time required for the printing process by the printing device 6 is very short, the stop period T2 'in the intermittent feeding period T of the film F by the intermittent feeding roller 5 is caused by the intermittent feeding roller 5 when the printing method during film feeding is used. Even when compared with the stop period T2 (see period T2 in FIG. 7) in the period T of intermittent feeding of the film F, the time difference is very small, and it is possible to perform intermittent film feeding substantially the same as the printing method during film feeding. .

  Although the conventional film transfer apparatus 101 shown in FIG. 13 can also employ a method of performing the printing process during the period in which the film F is intermittently fed, the speed of intermittent feeding of the film F is increased (cycle T). On the other hand, in order to secure a long stop period T2 in the period T in intermittent feeding, it is necessary to shorten the feeding period T1 in the period T by increasing the feeding speed v1 of the film F by the intermittent feeding motor 5.

  However, if the feeding speed v1 of the film F is excessively increased, there is a possibility that the time for the printing process by the printing device 6 cannot be ensured. In the conventional film transfer apparatus 101, the feeding speed v1 of the film F by the intermittent feeding motor 5 is reduced. There is a disadvantage that a certain limit occurs. On the other hand, in the film transfer apparatus 1 according to the first to third embodiments described above, as is apparent from FIGS. 7 and 11, the feeding speed v <b> 2 of the film F by the feeding motor 3 is set to the film F by the intermittent feeding motor 5. Therefore, there is no inconvenience that the feeding speed v2 of the film F by the feeding motor 3 is limited in relation to the printing speed by the printing device 6.

  That is, the film transfer apparatus 1 according to the first to third embodiments described above can employ both the printing method during film feeding and the printing method during film stop without impairing the degree of freedom in design. There are advantages.

  In the first to third embodiments described above, the strip-shaped film F on which the design G of the product label is printed in a line at regular intervals has been described. However, in the present invention, the design G is printed on the film F. Needless to say, the present invention can also be applied to the case where the uncut film F is intermittently fed at a constant size and cut by the label cutting device C. As such a film F, for example, a case where the film F is a translucent film F that is colored, cut into a fixed size, and wrapped in a transparent bottle for decoration can be considered.

  In addition, the present invention can be widely applied to a sheet material transfer device having a function of printing print data while feeding the film F when the belt-shaped sheet material F is fed and a fixed-size intermittent feed is performed downstream thereof. Needless to say.
