Description

  The present invention relates to a cutting plotter in which a winding device for winding a processed portion of a sheet material is provided in front of a support member on which a support surface on which a part of the sheet material is placed is formed.

  Such a cutting plotter includes a nipping and conveying mechanism for nipping a sheet material up and down on a support surface and conveying the sheet material back and forth, and a processing tool moving mechanism for moving a processing tool such as a cutter facing the support surface vertically. Is provided, and the cutting process is performed while moving the sheet material relative to the processing tool from front to back and from side to side by operating the clamping conveyance mechanism and the processing tool moving mechanism.

  A cutting plotter including a winding device that winds up a processed portion of a sheet material fed from a support member is known (see, for example, Patent Document 1). The winding device described in Patent Document 1 includes a torque limiter that limits a rotational driving force transmitted to a winding shaft around which a sheet material is wound. By the action of the torque limiter, the sheet material is always held in the state of being held by the holding and conveying mechanism even if the winding device is continuously operated.

  In this cutting plotter, by always operating the winding device, the processed portion of the sheet material can be wound by the winding device without slackening downward. As a result, the sheet material does not adhere to the ground and does not get dirty, and the processed material is always wound around the take-up shaft with tension applied, so the sheet material can be wound without being meandered or bent. Can be taken.

  However, when the winding device is operated in this manner, the processed portion of the sheet material fed from the support member to the winding device during processing is always in a tensioned state. Therefore, when the sheet material is fed backward during processing, it is possible to convey the sheet material by the action of the torque limiter itself, but the conveyance speed is higher than when the tension acting on the sheet material is increased and the sheet material is fed forward. May be slow. When the speed varies depending on the conveyance direction as described above, it is difficult to move the sheet material relative to the processing tool as expected, and it may be difficult to accurately process the sheet material.

  The present invention has been made in view of such problems, and it is possible to keep the sheet material conveyance speed by the nipping and moving mechanism constant while reducing the slack of the workpiece to be lowered by the operation of the winding device. An object of the present invention is to provide a cutting plotter that can be used.

In order to achieve the above object, a cutting plotter according to the present invention includes a support member having a support surface on which a part of a sheet material on which a plurality of processing objects are set in a plurality of rows and a plurality of columns is set, and a sheet A holding and conveying mechanism for holding the material up and down on the substantially same plane as the support surface and transferring the material back and forth; a processing tool moving mechanism for moving the processing tool provided above the support surface to the left and right; and a front of the support member A winding device that winds up a processed portion of the sheet material by applying a tension toward the front of the sheet material, and an operation control device that controls the operation of the nipping / conveying mechanism, the processing tool moving mechanism, and the winding device. The processing target is lined up and down by the processing tool while moving the sheet material on the support surface back and forth and from side to side with respect to the processing tool by operating the clamping conveyance mechanism and the processing tool moving mechanism by the operation control device. Control to convey a control for processing the one column, the processed portion of actuating the nipping and conveying mechanism sheet material portions machining subject to the following column is set conveys forward from the rear on the supporting surface for The present invention relates to a cutting plotter in which and are repeatedly performed. In addition, the operation control device controls to interrupt the processing of the sheet material by the processing tool when the sheet material is wound by the winding device , and when the processing by the processing tool is performed, The winding device is controlled so that the sheet material wound up in accordance with the rear conveyance can be fed backward, and the number of times the processing target for one row has been processed and the processed portion of the sheet material in front Each time at least one of the number of times the sheet is conveyed reaches the predetermined number, the sheet material conveyed forward by the nipping and conveying mechanism is wound by the winding device while the predetermined number of times of processing or conveyance is performed. It is characterized by being .

In addition, the winding device is configured to include a winding shaft that winds up the sheet material, and is configured so that the rotation drive of the winding shaft is controlled by the operation control device, and the winding shaft is controlled by the operation control device . sheet material by sandwiching the conveying mechanism in the prior resuming processing by the processing tool even after the sheet material is wound to stop the rotation of the winding shaft, the left to stop the rotation of the take-up shaft state The sheet material is controlled to be loosened between the support member and the winding device in order to allow the sheet material to be conveyed backward by the clamping conveyance mechanism when resuming processing by the processing tool. It is preferable.

Further, the winding device is driven so that the speed at which the sheet material is wound is higher than the speed at which the sheet material is conveyed by the clamping conveyance mechanism, and the processed portion of the sheet material is placed on the winding device by the operation control device. after being wound, in a state in which the action of tension forward to the sheet material by the winding device, preferably controlled to cause the transport to the front is carried out the machined portion of the sheet material from the support member by nipping and conveying mechanism .

  According to the cutting plotter according to the present invention configured as described above, the winding device is stopped during processing, and after the predetermined number of processings, the processing is interrupted and the winding device is operated. Thus, during processing, the tension does not act on the processed portion of the sheet material as in the prior art. Therefore, the conveyance speed can be kept constant regardless of whether the sheet material is conveyed forward or backward by the nipping and conveying mechanism during processing.

  In addition, after winding the processed part by the winding device and stopping the winding device, it is necessary to transport the sheet material immediately after resuming processing by operating the clamping conveyance mechanism to slightly loosen the processed part Even if there is, there is no possibility of excessive tension acting, and the conveyance speed during processing can be more reliably kept constant.

  In addition, the sheet material winding speed is configured to be faster than the conveyance speed, and the processed part on the support surface is sent out while operating the winding device, thereby applying tension to the processed part to be sent out. The winding device can be wound up. Thereby, when the sheet material is wound around the winding device, the sheet material can be accurately wound around the winding device without meandering left and right.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. First, the apparatus configuration of the cutting plotter CP will be described with reference to FIG. For convenience of explanation, the directions of arrows indicated as “front”, “left”, and “up” in the figure are respectively forward, left, and upward.

  The cutting plotter CP is composed of a leg 2 having struts 2b extending up and down on both left and right ends of a base 2a close to the ground, and a support body 1 installed in an upright state. A platen 10 that extends to support a part of the sheet material 100, a pair of upper and lower feed rollers 11 and a presser roller 12 that sandwich the sheet material 100 up and down and conveys it back and forth, And a head 20 attached to a guide rail 15 extending horizontally. The platen 10 and the guide rail 15 are supported on the left and right by the cover 5 provided at the upper end of the support 1.

  The platen 10 has a front and rear central portion extending horizontally and front and rear end portions curved downward, so that the sheet material 100 can be horizontally placed and supported on the upper surface 10a of the front and rear central portion. It has become.

  The platen 10 is provided with a plurality of sets of feed rollers 11 and pressing rollers 12 with the front and rear central portions arranged side by side. Each feed roller 11 is provided on the lower side (inside) of the platen 10 and is driven to rotate in synchronization with the forward and reverse directions by an electric motor 51 including a servo motor. A plurality of through holes are formed in the platen 10 at predetermined intervals on the left and right, and the feed roller 11 has a part of the outer peripheral surface 11a facing the upper surface 10a through the through holes. The presser roller 12 is provided on the upper side (outer side) of the platen 10, and a clamping position (solid line) that is opposed to the feed roller 11 in the vertical direction substantially on the same plane as the upper surface 10 a of the front and rear center part of the platen 10, and the platen 10 It is possible to move between the retracted position (two-dot chain line) retracted upward.

  The head 20 is horizontally movable along the guide rail 15 by the electric motor 52. On the lower surface of the head 20, a cutter 21 that protrudes downward and cuts the sheet material 100 is detachably attached. The cutter 21 can move left and right above the front and rear central portions of the platen 10. The head 20 is configured to be movable up and down with respect to the guide rail 15, and the cutter 21 can be moved up and down.

  In this cutting plotter CP, when the sheet material 100 is supplied to the platen 10 from the rear side and the presser roller 12 is positioned at the clamping position, the sheet material 100 is sandwiched up and down by the feed roller 11 and the presser roller 12, and the platen 10. Is supported by the upper surface 10a. In this state, the sheet material 100 is fed forward by rotating the feed roller 11 in the forward direction (arrow R1 direction), and the sheet material 100 is fed backward by rotating in the reverse direction (arrow R2 direction). . At this time, the head 20 is moved downward to bring the cutter 21 into contact with the sheet material 100, and the head 20 is moved to the left and right to move the sheet material 100 relative to the cutter 21 from front to back and left and right. Processing can be performed. In the present embodiment, the unprocessed portion of the sheet material 100 is sent to the platen 10 from the rear, and the processed portion of the sheet material 100 is sent to the front of the platen 10.

  A winding device 30 is fixed to the support 1 at the front lower side of the platen 10 via a pair of left and right front brackets 3 that extend forward from the column 2b, and extends backward from the column 2b. The support mechanism 40 is fixed to the lower rear of the platen 10 via the left and right rear brackets 4.

  The winding device 30 is configured by rotatably providing a cylindrical winding shaft 31 for winding the sheet material 100. The winding shaft 31 is rotationally driven in a predetermined direction by an electric motor 53. By rotating the take-up shaft 31, the processed portion of the sheet material 100 fed forward from the platen 10 can be taken up. The support mechanism 40 includes two support bars 41 and 42 that extend in the left-right direction and are arranged in the front-rear direction. The unsupported sheet material 100 is placed and supported on these two support bars 41 and 42 while being rolled.

  The cutting plotter CP is provided with an operation control device 50 that performs drive control of the electric motors 51 to 53. By the drive control of the electric motors 51 to 53 performed by the operation control device 50, the operation of the feed roller 11, the head 20, and the winding device 30 is controlled.

  The winding device 30 is provided with a torque limiter 32 that limits the torque transmitted from the drive motor 53 to the winding shaft 31 to a predetermined value or less. Even when the winding shaft 31 of the winding device 30 is rotationally driven by the action of the torque limiter 32 while the feeding roller 11 is stopped, the sheet material 100 is sandwiched between the feeding roller 11 and the pressing roller 12. Therefore, the upper surface 10a of the platen 10 is not slipped forward.

  On the other hand, a large torque is transmitted to the feed roller 11 from the drive motor 51, and the winding shaft 31 of the winding device 30 is coupled with the fact that the sheet material 100 is firmly held together with the pressing roller 12. When the feed roller 11 is driven in the reverse direction in the stopped state, the wound sheet material 100 is returned to the platen 10 side.

  The speed at which the sheet material 100 is wound by the winding device 30 (winding speed) is configured to be faster than the speed at which the sheet material 100 is fed by the feed roller 11 (conveyance speed). However, due to the action of the torque limiter 32, even if the winding device 30 is operated in a state where the processed portion is not loosened and the feed roller 11 is rotating in the forward direction, the sheet material 100 slips in the same manner as described above. Without being fed forward from the platen 10.

  FIG. 2 illustrates the sheet material 100. The sheet material 100 is formed by sticking a sticker paper 102 to an upper surface of a mount 101 in a peelable manner. .. Are printed on the surface of the sticker paper 102, and the drawing areas 110, 110,... It is out. A predetermined design (not shown) is printed inside each drawing area 110. By the cutting plotter CP, the cutter 21 cuts only the sticker paper 102 into a shape (processing target) along the outline of the symbol printed inside each drawing area 110.

  In performing this processing, first, a portion of the sheet material 100 supplied from the rear side of the platen 10 on which the drawing data that divides the drawing area in the front row is printed is supported on the upper surface 10 a of the platen 10. Then, the processing objects arranged in the foremost row on the left and right are sequentially processed from the processing object at the right end (corresponding to step S1 in FIG. 3). When the processing for all the processing objects arranged on the left and right in the front row is completed, the feed roller 11 is rotated in the forward direction, the processed portion is fed forward from the platen 10, and the drawing area in the second row from the front is defined. The portion on which the drawing data is printed is sent from behind and supported by the upper surface 10a of the platen 10 (corresponding to step S3 in FIG. 3). The second row of workpieces are processed sequentially from the right side in the same manner as described above. After the processing is completed, the feed roller 11 is rotationally driven in the forward direction, the processed portion is sent out, and the unprocessed portion is supported on the upper surface 10a. Is done. Thereafter, the same operation is repeated until the processing on the processing target in the last row is completed. This operation is performed by driving control of the drive motors 51 and 52 by the operation control device 50.

  Regarding the processing for each design, the cutter 21 is appropriately moved up and down to be separated from and contacted with the seal paper 102, and the sheet material 100 is moved relative to the cutter 21 in the front-rear and left-right directions. The head 20 is driven left and right while being rotated in the direction. The operation control device 50 controls the operation of the feed roller 11 and the head 20 by drivingly controlling the electric motors 51 and 52 in accordance with a predetermined order in order to cause the sheet material 100 to move relative to the front, rear, left and right.

  Next, an operation control method for the winding device 30 and the like performed by the operation control device 50 will be described with reference to FIG. When the processing (step S1) for the processing objects arranged in the left and right in a certain row as described above is completed, it is determined whether or not the number of times of processing in the left and right direction has reached a predetermined number (step S2). When it is determined that the specified number has not been reached, the processed portion supported by the upper surface 10a is sent forward as described above, and the unprocessed portion in the next row is sent from the rear to the upper surface 10a of the platen 10 ( Step S3). Next, it is determined whether or not all the processing (that is, processing for the processing target in the last row) has been completed (step S4). If it is determined that the processing has been completed, predetermined end processing is performed (step S5). ), The process is terminated. If it is determined that the processing has not been completed, the process returns to step S1 to perform the processing for the processing target in the next row.

  If it is determined in step S2 that the specified number has been reached, a sheet winding process (step S10) including the following steps S11 to S15 is performed. As shown in FIG. 3, the processing is interrupted while the sheet winding process is being performed, and the winding device 30 is stopped during the processing so that the sheet winding process is not performed. Yes. Until the specified number is reached, steps S1 to S4 are repeated and the processed portion of the sheet material 100 continues to be sent forward. However, this specified number may cause the sheet material 100 sent forward to adhere to the ground. It is set not to.

  In this sheet winding process, first, the electric motor 53 is driven to operate the winding device 30 (step S11). Until the specified number is reached, the process of feeding the processed portion forward in step S3 is repeated, so that the processed portion of the sheet material 100 is slackened below the winding device 30. By actuating the winding device 30, the slack portion is wound around the winding device 30, and the processed portion of the sheet material 100 is tensioned between the feeding roller 11, the pressing roller 12 and the winding device 30. Will be in the state that acted.

  Then, the feed roller 11 is rotationally driven in the forward direction, and the processed portion of the sheet material 100 is fed forward (step S12). Although the same operation as step S3 is performed, when the step S12 is performed, the winding device 30 is continuously operated. As described above, since the winding speed by the winding device 30 is set faster than the conveying speed by the feed roller 11, the sheet material 100 is applied to the winding device 30 in a state where tension is applied to the processed portion of the sheet material. Can be wound up.

  When the processed part of the sheet material 100 is sent out and the unprocessed part in the next row is supported by the upper surface 10a, the feeding roller 11 is stopped and the winding device 30 is stopped (step S13). Here, the operation time of the winding device 30 in step S11 is determined by the operation control device 50 based on the longitudinal length of the processing objects arranged in a row, the specified number specified in step S2, and the winding speed. The time can be set in advance, and control using a special sensor or the like is not required. Similarly, the operation time of the feed roller 11 that operates together with the winding device 30 in step S12 and the operation time of the feed roller 11 in step S3 are also based on the longitudinal length of the workpieces arranged in a row and the conveyance speed. Thus, the operation control device 50 can set the time in advance. As described above, due to the action of the torque limiter 32, the sheet material 100 does not slip to the winding device 30 side even if the winding device 30 is operated in a state where tension is applied to the processed portion of the sheet material 100. If the sheet material 100 is conveyed by a length assumed in advance, the unprocessed portion in the next row can be accurately supported on the upper surface 10a. Similarly, even if the winding device 30 is operated in a state where the feed roller 11 is stopped, the sheet material 100 does not slip to the winding device 30 side, so the stop timing of the winding device 30 in step S13 needs to be set severely. In addition, there is no need to set the braking response of the winding shaft 31 severely.

  Then, the feed roller 11 is rotationally driven in the reverse direction, and the sheet material 100 is fed backward by a predetermined length (step S14). As described above, when the feed roller 11 is driven in the reverse direction while the winding device 30 is stopped, the sheet material 100 wound around the winding shaft 31 is also fed back to the platen 10 side. Thereby, the part where the processing object of the next row supported by the upper surface 10a of the platen 10 is set is sent back.

  Further, the feed roller 11 is rotationally driven in the forward direction to feed the sheet material 100 forward (step S15). The transport length at this time is set to the same length as the backward transport length in step S14. As a result, the upper surface 10a of the platen 10 is in a state where the portion where the processing target of the next row sent rearward is set is supported by the upper surface 10a of the platen 10 again. Further, the sheet material 100 is slightly loosened between the platen 10 and the winding device 30 according to the transport length in step S14. When step S14 ends, the process returns to step S4.

  In addition, before returning to step S4 and returning to step S1 and performing the processing for the processing objects arranged on the left and right in the next row, the accumulated processing number to be compared with the designated number in step S2 is reset. That is, the sheet winding process (step S10) is performed every time the specified number of times of processing is performed, and the processing using the cutter 21 performed in a state where the winding device 30 is stopped; Sheet winding processing using the winding device 30 performed in a state where the cutter 21 is separated upward from the sheet material 100 and the head 20 is stopped is alternately performed.

  Thus, in the cutting plotter CP, the winding device 30 is stopped during the processing (step S1), and the processing is interrupted while the winding device 30 is operating (step S11). The tension does not act on the processed part of the metal as in the past. Therefore, even when the feeding roller 11 is driven in the forward / reverse direction during processing to convey the sheet material 100 back and forth, the conveyance speed can be kept constant.

  In addition, after the processed portion is wound by the winding device and the winding device is stopped (step S13), the sheet material 100 is conveyed backward (step S14) and further conveyed forward (step S15). The sheet material 100 is slightly loosened below the winding device 30 before returning to step S1 and resuming the processing. Thereby, for example, even if it is necessary to transport the sheet material 100 rearward immediately after resuming processing, there is no possibility that excessive tension acts on the sheet material 100, and the transport speed during processing can be more reliably kept constant. it can.

  Further, the winding speed by the winding device 30 is configured to be higher than the conveying speed by the feed roller 11, and the processed portion of the sheet material 100 supported by the upper surface 10a is sent out while operating the winding device 30. (Step S12), the winding device 30 can be wound while applying tension to the processed portion to be sent out. Thereby, when the sheet material 100 is wound around the winding device 30, the sheet material 100 can be accurately wound around the winding device 30 without meandering left and right.

  So far, the cutting plotter according to the present invention has been described, but the present invention is not limited to the above configuration. The designated number of times used for the determination process in step S2 may be the number of times the processed part of the sheet material 100 is sent forward in step S3, or both the number of times of processing in the left and right direction and the number of times of being sent forward are set. May be.

  FIG. 4 shows a second cutting plotter CP2 as a modified configuration example of the cutting plotter according to the present invention. In this cutting plotter CP2, the support mechanism 40 provided in the cutting plotter CP shown in FIG. 1 is omitted, and instead, an inkjet plotter IP is provided at the rear of the apparatus. The support 1, the platen 10, the head 20, the winding device 30, and the electric motors 51 to 53 are configured in the same manner as the cutting plotter CP. Further, the operation control device 50 is also configured to perform the processing shown in FIG.

  The ink jet plotter IP includes a support 201, a platen 210, a feed roller 211, and a presser roller 212 having the same configuration as the cutting plotters CP and CP2. A guide rail 215 extending left and right is provided above the platen 210, and a head 220 incorporating the inkjet nozzle 221 is attached along the guide rail 215 so as to be movable left and right. In addition, a support mechanism 240 that supports the seat 100 is fixed to the support body 201 via the rear bracket 204, located at the lower rear side of the platen 210. The support mechanism 240 has the same configuration as the cutting plotter CP, and can support the rolled plain sheet material 100.

  According to such an inkjet plotter IP, the plain sheet material 100 supported by the support mechanism 240 is supplied from the rear side to the platen 210 in accordance with the rotation of the feed roller 211, and is discharged from the platen 210 to the front side. When the sheet material 100 passes through the platen 210, ink is ejected from the head 220 onto the surface, and the drawing data 111, 111,... Is printed as shown in FIG. A predetermined pattern is printed inside the drawing area.

  The cutting plotter CP and the inkjet plotter IP are connected back and forth via a connecting member 161 straddling the bases 2a and 202a, whereby the left and right centers of the platens 10 and 210 are aligned forward and backward. The sheet material 100 that has been printed and sent to the front of the platen 210 of the ink jet plotter IP is supplied to the platen 10 of the cutting plotter CP2 from the rear side. Photosensors 171a and 171b that are horizontally opposed to each other are provided on the respective bases 2a and 202a. The cutting plotter CP and the inkjet plotter IP operate so that the detection light 170 emitted from the light-emitting side photosensor 171a is always blocked by the printed portion of the sheet material 100. That is, the printed portion of the sheet material 100 is slackened to the vicinity of the bases 2a and 202a, so that excessive tension does not act on the sheet material 100 supported by the upper surfaces 10a and 210a of the platens 10 and 210. It has become. The sheet material 100 sent to the platen 10 of the cutting plotter CP2 is processed by the cutter 21 and sent forward, and the sheet winding process (step S10) shown in FIG. Taken.

  Even with such an apparatus configuration, the front and rear sheet conveying speeds can be kept constant, and the sheet material can be wound without meandering, as with the cutting plotter CP.
