  By the way, depending on the production facility to be equipped with the tape applicator, it may be necessary to apply a double-sided tape piece to the workpiece in the process of conveyance.

  However, when the double-sided tape piece is attached to the workpiece in the process of conveyance using the tape sticking device of Patent Document 1, the composite tape is dragged to the work while the double-sided tape piece is in contact with the work. There is a possibility that. If this happens, the head end of the double-sided tape piece waiting to be attached to the workpiece next will be sent to the downstream side beyond the proper standby position, and the position of the head end will vary each time the attachment is made. There is a possibility. Thus, if the head end of the double-sided tape piece cannot be made to stand by at an appropriate standby position, there is a possibility that the double-sided tape piece may be stuck at an undesired location.

  In view of this, the present invention provides a tape applicator for sequentially adhering the double-sided tape pieces to the workpiece in order to allow the double-sided tape pieces to stand by at an appropriate standby position and thereby suitably attach the double-sided tape pieces. The purpose is to do.

  The present invention has been made to achieve the above object, and the tape applicator according to the present invention is such that the double-sided tape is peeled off in the middle of the composite tape holding the double-sided tape having adhesiveness on both sides with the peeling tape. A travel path that travels as a remaining tape, a reel on which the composite tape is wound is rotatably supported, a feeding device that applies back tension to the composite tape drawn from the reel, and the feeding device. A winding device that pulls out the composite tape from the reel of the delivery device by feeding the composite tape passed through the travel path and the residual tape and winding the residual tape; and a composite tape drawn from the reel Of these, only the double-sided tape is divided in the longitudinal direction of the composite tape to create a double-sided tape piece held by a release tape. The cutting device and the head end of the double-sided tape piece assumed on the traveling path and held by the peeling tape are positioned with respect to the work being conveyed through the work conveyance path, and the positioned double-sided tape piece is placed on standby. A standby position, a sticking part for peeling the positioned double-sided tape piece from the peeling tape and attaching it to a workpiece, a controller for controlling operations of the cutting device, the feeding device, and the winding device; The feeding device and the winding device are configured to be able to feed and return the composite tape and the remaining tape, and the controller intermittently feeds the composite tape and the remaining tape. The double-sided tape piece is created, the double-sided tape piece is positioned, and the double-sided tape piece is attached to the workpiece, and the double-sided tape piece is positioned. , Said composite tape and the remaining tape the cutting device to make sure to send after returning to the delivery device, and is configured to control the winding device.

  According to the above configuration, when the double-sided tape piece is attached to the workpiece in the process of conveyance, the head end of the double-sided tape piece to be attached to the workpiece next exceeds the proper standby position, Even if the position of the head end may vary each time it is applied, the head end of the double-sided tape piece to be applied to the workpiece is preferably placed in the standby position before being applied to the workpiece. Can be positioned. Thereafter, the double-sided tape piece positioned at the standby position is attached to the workpiece while being peeled off from the release tape by the attaching portion. Since the head end of the double-sided tape piece is positioned at an appropriate standby position before being attached, the head end of the double-sided tape piece can be brought into contact with a desired position of the workpiece and suitably attached.

  The feeding device includes a feeding motor that generates a rotational driving force for feeding and returning the composite tape and the remaining tape, and the winding device generates a rotational driving force for feeding and returning the composite tape and the remaining tape. A motor, and the controller gives a command for generating a rotational driving force for feeding the composite tape and the remaining tape to the take-up motor and generates a rotational driving force for returning the composite tape and the remaining tape to the feeding motor. And when the composite tape and the remaining tape are sent, a rotational driving force for returning the composite tape and the remaining tape of the feeding motor from a rotational driving force for feeding the composite tape and the remaining tape of the winding motor is When the composite tape and the remaining tape are small, the front of the take-up motor It may be configured to give commands to the take-up motor and the delivery motor, respectively, so that the rotational drive force for returning the composite tape and the remaining tape of the delivery motor is larger than the rotational drive force for delivering the composite tape and the remaining tape. Good.

  According to the said structure, when sending a composite tape and a residual tape, a sending-out motor will generate reverse torque, and when returning a composite tape and a residual tape, a winding motor will generate reverse torque. Then, the traveling direction of the composite tape and the remaining tape can be changed only by adjusting the rotational driving force of the feed motor and the take-up motor. Therefore, the direction of travel of the composite tape and the remaining tape can be quickly changed as compared with the case where the tension is applied to the composite tape and the remaining tape by the braking motor generating the braking torque.

  The controller, when sending the composite tape and the remaining tape, gives a command to the delivery motor to set the current limit value of the delivery motor to the first current value, and when returning the composite tape and the remaining tape, The feed motor may be configured to give a command so that a current limit value of the feed motor is set to a second current value larger than the first current value.

  According to the above configuration, since the rotational driving force of the feed motor can be adjusted only by changing the current limit value, the control for feeding and returning the composite tape and the remaining tape can be easily performed.

  The controller may be configured to control the feeding device and the winding device so that the double-sided tape piece is attached to the workpiece by feeding the composite tape and the remaining tape.

  The feeding device includes a feeding motor that generates a rotational driving force for feeding and returning the composite tape and the remaining tape, and the winding device generates a rotational driving force for feeding and returning the composite tape and the remaining tape. A winding motor is provided, and the controller gives a command to generate a rotational driving force for feeding the composite tape and the remaining tape to the winding motor, and a rotational driving force for returning the composite tape and the remaining tape to the feeding motor. When the composite tape and the remaining tape are sent, the rotational driving force for feeding the composite tape and the remaining tape of the feeding motor is less than the rotational driving force for feeding the composite tape and the remaining tape of the take-up motor. Give commands to the take-up motor and the feed motor so that they become smaller. In addition, when the composite tape and the remaining tape are fed in a state where the double-sided tape piece is not in contact with the work, a command is given to the feed motor so that the current limit value of the feed motor becomes a first current value, and When the composite tape and the remaining tape are fed in a state where the tape piece is in contact with the workpiece, a command is given to the feeding motor so that the current limiting value of the feeding motor is set to a third current value larger than the first current value. It may be configured to give.

  According to the above configuration, when sending the composite tape and the remaining tape, when the double-sided tape piece is in contact with the workpiece, the feeding device generates a larger reverse torque than when it is not in contact with the workpiece. Become. Thereby, when a double-sided tape piece is affixed to the work in the process of conveyance, it becomes possible to suppress the composite tape from being dragged to the work as much as possible. Further, when the tape is not in contact with the workpiece, the reverse torque can be reduced to increase the running speed of the composite tape and the remaining tape as much as possible.

  As described above, according to the present invention, in the tape applicator for sequentially adhering the double-sided tape pieces to the workpiece, the double-sided tape pieces can be waited at an appropriate standby position, thereby making the double-sided tape pieces suitable.

The production facility 1 shown in FIG. 1A is a facility for producing, for example, a solar panel (solar power generation panel: not shown), and a long rail 2 is bonded to the surface of the solar panel. It has sections that are glued together This section includes a rail transport device 3 that transports the rail 2 along the rail transport path 3a, and the rail transport path 3a extends in the horizontal front-rear direction. The rail conveyance device 3 sequentially conveys the rails 2 in the forward direction with the adherend surface 2a of the rails 2 facing upward and the longitudinal direction of the rails 2 oriented in the horizontal front-rear direction.

  In addition, this section includes a tape applying device 10 for attaching the double-sided tape piece 5 a of the composite tape 4 to the adherend surface 2 a of the rail 2. The tape applicator 10 is paired in the left-right direction with the rail conveying device 3 in between, and by the pair of tape applicators 10, a double-sided tape piece is formed on both the left and right edges of the adherend surface 2a. 5a is pasted. Each tape applicator 10 applies a plurality of double-sided tape pieces 5a at intervals along the longitudinal direction of the rail 2 to the left side edge and the right side edge of the adherend surface 2a. At this time, each tape applicator 10 sequentially attaches the double-sided tape pieces 5a to the adherend surface 2a of the rail 2 in the conveying process.

[Composite tape]
FIG.1 (b) is a perspective view of the composite tape 4 utilized for the tape sticking apparatus 10 shown to Fig.1 (a). As shown in FIG. 1B, the composite tape 4 has a two-layer structure in which one side of a double-sided tape 5 having adhesiveness on both sides is held on one side of a release tape 6. The double-sided tape piece 5 a is created by dividing the double-sided tape 5 in the longitudinal direction of the composite tape 4 with the cutter 37 of the tape applicator 10. The double-sided tape 5 has a thickness of about 2 mm, for example, and the release tape 6 has a thickness of less than 1 mm, for example. The double-sided tape 5 and the release tape 6 have the same width of about 25 mm, for example.

[Tape sticking device]
FIG. 2 is a side view of the tape applicator 10 shown in FIG. As shown in FIG. 2, the tape sticking device 10 includes a base 11 erected on the side of the rail conveyance device 3. A movable body 12 is held on the base 11 so as to be movable in the vertical direction. The movable body 12 is connected to a pasting motor 14 via a mechanism 13 that converts rotation into a linear motion, for example, a ball screw mechanism. When the affixing motor 14 is operated, the movable body 12 moves upward or downward according to the rotation direction of the affixing motor 14 by the action of the mechanism 13.

  The tape applicator 10 includes a delivery device 50 that rotatably supports a delivery reel 4a around which the composite tape 4 is wound, and peeling in a state where the double-sided tape 5 is peeled from the composite tape 4 by being attached to the rail 2. A take-up device 55 for taking up the remaining tape 6b, which is the tape 6, is provided. The take-up device 55 supports a take-up reel 6a on which the remaining tape 6b is wound. Between the delivery device 50 and the take-up device 55 (or between the delivery reel 4a and the take-up reel 6a), a travel path 30 on which the composite tape 4 and the remaining tape 6b travel is formed. In the middle of the traveling path 30, the double-sided tape 5 is peeled off by being attached to the rail 2 to become the remaining tape 6. Hereinafter, the side on which the delivery reel 4a is disposed along the travel path 30 may be described as the upstream side of the travel path 30, and the side on which the take-up reel 6a is disposed is described as the downstream side of the travel path 30. Further, the description will be made on the assumption that the composite tape 4 and the remaining tape 6b are traveled downstream along the travel path 30 as “send” and the travel toward the upstream side is “return”.

  The composite tape 4 and the remaining tape 6b travel along the travel path 30 in accordance with the operations of the feeding device 50 and the winding device 55. The delivery device 50 includes a delivery roller 15 that detachably and rotatably supports the delivery reel 4a, and applies back tension to the composite tape 4 that is drawn out from the delivery reel 4a through the travel path 30. It is configured. The take-up device 55 includes a take-up roller 16 that supports the take-up reel 6a, a pulling roller 27, and a pinch roller 34. The take-up device 55 passes the composite tape 4 and the remaining tape 6b that are passed from the sending device 50 to the travel path 30. The composite tape 4 is pulled out from the delivery reel 4a by feeding and winding the remaining tape 6b. The travel path 30 is composed of a plurality of guide rollers 17 to 26 and a pulling roller 27, and the composite tape 4 and the remaining tape 6 b pulled out from the delivery reel 4 a are attached to the outer peripheral surfaces of the guide rollers 17 to 26. The guide rollers are sequentially wound in the order of reference numerals attached thereto, and finally wound around the outer peripheral surface of the pulling roller 27. The delivery roller 15 is always configured to generate a rotational driving force for returning the composite tape 4 and the remaining tape 6b. The composite tape 4 and the remaining tape 6b are moved on the travel path 30 by the back tension applied by the delivery device 50. With no slack.

  The feed roller 15 and the take-up roller 16 are attached to the base 11, and the guide rollers 17 to 26 and the pulling roller 27 are attached to the base 11 or the movable body 12. Each of the rollers 15 to 27 is rotatable in the forward and reverse directions around an axis extending in the left-right direction (that is, a direction perpendicular to and horizontal with respect to the rail 2 conveyance direction). Therefore, the width direction of the composite tape 4 and the remaining tape 6b is directed in the left-right direction.

[Running route / Cutting device / Paste part]
With reference to FIG.2 and FIG.3, it demonstrates from the upstream (the side by which the delivery reel 4a is arrange | positioned) about the traveling path 30. FIG. As shown in FIG. 2, the travel path 30 first extends substantially downward from the delivery reel 4 a, is folded back at a substantially right angle, extends horizontally in the rearward direction, is folded back at an acute angle, and extends while being inclined downward.

  That is, the composite tape 4 pulled out from the delivery reel 4 a is sequentially applied to the outer peripheral surface of the guide roller 17 positioned below the supply roller 15 and the outer peripheral surface of the guide roller 18 positioned below the guide roller 17. Wrapped. The composite tape 4 is wound around the guide rollers 17 and 18 with the double-sided tape 5 facing inward. For this reason, the outer peripheral surfaces of the guide rollers 17 and 18 are formed from a material in which the double-sided tape 5 is difficult to stick and the double-sided tape 5 is difficult to slip, so that the composite tape 4 follows the outer peripheral surfaces of the guide rollers 17 and 18. And run smoothly.

  As shown in FIG. 3, the composite tape 4 is drawn horizontally rearward from the guide roller 18, and is wound with the release sheet 6 facing inwardly on the outer peripheral surface of the guide roller 19 located behind the guide roller 18. It has been. For this reason, the composite tape 4 is guided between the guide rollers 18 and 19 in a posture in which the double-sided tape 5 is directed upward and the peeling tape 6 is directed downward.

  The composite tape 4 is cut by the cutting device 35 while traveling between the guide rollers 18 and 19. The cutting device 35 includes a cutter actuator 36 fixed to the movable body 12, and the cutter actuator 36 is located above the travel path 30 formed between the guide rollers 18 and 19. The cutter actuator 36 is made of, for example, an air cylinder, and holds the cutter 37 in a posture in which the cutting edge is directed downward. By driving the cutter actuator 36 by supplying and discharging air or the like, the cutter 37 moves forward and backward. The cutting edge of the cutter 37 extends horizontally in the left-right direction (see FIG. 1B) and has a dimension in the left-right direction that is slightly larger than the width of the composite tape 4.

  When the cutter 37 advances downward, the cutting edge of the cutter 37 reaches the surface of the double-sided tape 5 facing upward, and then exceeds the distance corresponding to the thickness of the double-sided tape 5 and the entire composite tape 4 It proceeds further downward by less than a distance corresponding to the thickness. Then, only the double-sided tape 5 is divided in the longitudinal direction of the composite tape 4 without dividing the release tape 6. By alternately feeding the composite tape 4 along the traveling path 30 and such an operation of the cutter 37, the double-sided tape pieces 5a held by the peeling tape 6 are sequentially formed.

  The composite tape 4 in a state where the double-sided tape piece 5a is held by the release tape 6 is folded back at an acute angle by the guide roller 19 and pulled out forward and downward. Next, the composite tape 4 is wound around the outer peripheral surface of the guide roller 20 positioned forward and below the guide roller 19 and the outer peripheral surface of the guide roller 21 positioned further forward and lower than the guide roller 20 in this order. It is done. The composite tape 4 is wound around these guide rollers 19, 20, 21 with the release tape 6 facing inward. As a result, the composite tape 4 is guided between the guide rollers 19 and 21 in such a posture that the double-sided tape piece 5a faces substantially downward and the peeling tape 6 faces substantially upward.

  The tape applicator 10 guides the head end of the double-sided tape piece 5a located on the most downstream side between the guide rollers 19 and 21 (that is, the transition between the composite tape 4 and the remaining tape 6b) on the travel path 30. Positioning is performed at a predetermined standby position assumed near the outer peripheral surface of the roller 21. Thereby, the composite tape 4 is guided so that the head end of the double-sided tape piece 5a faces the rail conveyance path 3a. Thereafter, the movable body 12 is moved downward, and the double-sided tape piece 5a is brought into contact with the adherend surface 2a of the rail 2 in the conveying process. Then, by sending the composite tape 4 and the remaining tape 6b, in the vicinity of the outer peripheral surface of the guide roller 21, the composite tape and the remaining tape 6b travel in a substantially forward direction that is substantially parallel to the direction in which the rail 2 is conveyed. As a result, the double-sided tape piece 5 a is attached to the adherend surface 2 a of the rail 2 while being peeled from the peeling tape 6. Then, the composite tape 4 travels as the remaining tape 6b on the downstream side of the travel path 30 from the vicinity of the outer peripheral surface of the guide roller 21. As described above, the movable body 12, the attaching motor 14, and the guide rollers 19 to 21 position the double-sided tape piece 5 a at the standby position before being attached to the rail 2, and wait for the double-sided tape piece 5 a to be positioned. Is attached to the rail 2 by being peeled from the release tape 6.

  The tape applicator 10 is a position that detects whether or not the head end of the double-sided tape piece 5a that is positioned on the most downstream side and waits for the next application to the rail 2 has reached the predetermined standby position. A sensor 45 is provided. For example, the position sensor 45 is composed of a reflective optical sensor that emits inspection light horizontally in the left-right direction. In this case, if the head end of the double-sided tape piece 5a has reached the standby position, the inspection light emitted from the light projecting element is reflected by the side surface of the double-sided tape piece 5a, and the light receiving element receives the reflected light, The position sensor 45 outputs an on signal. If the head of the double-sided tape piece 5a does not reach the standby position (that is, if the remaining tape 6b is in the standby position), the inspection light cannot be reflected by the double-sided tape piece 5a, and the position sensor 45 is turned off. Output a signal.

Returning to FIG. 2, the remaining tape 6 b is folded back at an acute angle by the guide roller 21, pulled substantially upward from the guide roller 21, and wound around the outer peripheral surface of the guide roller 22 positioned above the guide roller 21. ing. Then, the remaining tape 6 b is folded back by the guide roller 22 and is wound around the outer peripheral surface of the guide roller 23 positioned in front of the guide roller 22. Next, the remaining tape 6b is folded at a right angle by the guide roller 23, drawn upward from the guide roller 23, wound around the outer peripheral surface of the guide roller 24 positioned above the guide roller 23, and guided by the guide roller. 24, it is folded 180 degrees from the guide roller 24, is wound around the outer peripheral surface of the guide roller 25 positioned below the guide roller 24, is folded again 180 degrees by the guide roller 25, and is guided. It is drawn upward from the roller 25 and wound around the outer peripheral surface of the guide roller 26 positioned above the guide roller 25. As described above, the guide rollers 23 to 26 constitute a trap portion 29 that turns back the travel path of the remaining tape 6b twice continuously 180 degrees. The trap portion 29 folds the traveling path of the remaining tape 6b along the vertical direction (that is, the moving direction of the movable body 12). Next, the remaining tape 6b is folded back at a substantially right angle or acute angle by the guide roller 26, pulled forward from the guide roller 26, and pulled to the front of the guide roller 26 and below the take-up reel 6a. It is wound around the outer peripheral surface of the roller 27, folded back at a substantially right angle by the pulling roller 27, drawn upward from the pulling inner roller 27, and continuous with the outer peripheral surface of the take-up reel 6a.
[Feeding device / winding device]
The delivery device 50 and the take-up device 55 send and return the composite tape 4 and the remaining tape 6b along the traveling path 30 formed as described above, and further, the composite tape 4 and the remaining tape on the traveling path 30. 6b can be stopped.

  The delivery device 50 includes the delivery roller 15 and the delivery motor 31 described above. The delivery motor 31 generates a rotational driving force that feeds and returns the composite tape 4 and the remaining tape 6b. The rotational driving force generated by the delivery motor 31 is transmitted to the delivery roller 15.

  The winding device 55 includes the winding roller 16, the pulling roller 27, the pinch roller 34, and the winding motor 32 described above. The take-up motor 32 generates a rotational driving force for feeding and returning the composite tape 4 and the remaining tape 6b. The rotational driving force generated by the winding motor 32 is transmitted to the pulling roller 27. An endless belt 33 is wound between the pulling roller 27 and the take-up roller 16, and the rotational driving force transmitted to the pulling roller 27 is transmitted to the take-up roller 16 through the endless belt 33 that circulates. Is done.

  The winding device 55 includes a slip mechanism (not shown) that generates an appropriate slip torque between the endless belt 33 and the winding roller 16 or between the winding roller 16 and the winding reel 6a. Further, the peripheral speed of the body of the take-up reel 6a when the remaining tape 6b is not wound may be designed to be larger than the peripheral speed of the pulling roller 27. In this case, the pulling roller 27 pulls and feeds the remaining tape 6b, and the remaining tape 6b can be wound with the slip torque while the take-up reel 6a slips against the rotation of the pulling roller 27.

  The pinch roller 34 is provided on the base 11 so as to be able to contact and separate from the pulling roller 27. When sending the composite tape 4 and the remaining tape 6b, the pinch roller 34 is pressed against the pulling roller 27 across the remaining tape 6b wound around the pulling roller 27, and the remaining tape 6b slips against the pulling roller 27. Is prevented. On the other hand, when returning the composite tape 4 and the remaining tape 6 b, the pinch roller 34 may be separated from the pulling roller 27, thereby allowing the remaining tape 6 b to slip with respect to the pulling roller 27. The composite tape 4 and the remaining tape 6b can be suitably fed and returned by the feeding device 50 and the winding device 55.

  However, the configurations of the feeding device 50 and the winding device 55 shown in FIG. 2 are examples, and can be changed as appropriate. For example, the feeding device 50 may be composed of a pulling roller and a feeding roller provided with a slip mechanism like the winding device 55. Conversely, the take-up device 55 may be constituted by a take-up roller capable of generating a traction force by omitting the traction roller and the slip mechanism, like the delivery device 50.

Both the delivery motor 31 and the take-up motor 32 are, for example, DC servo motors, and are controlled by the controller 40 (see FIG. 4). As will be described later, the controller 40 controls the rotational positions of the feed motor 31 and the take-up motor 32 to control the rotation, stop, and rotational driving force of the feed motor 31 and the take-up motor 32, respectively. The pulling force applied to the composite tape 4 and the remaining tape 6b is controlled.
[Control system]
FIG. 4 is a block diagram showing the configuration of the control system of the tape applicator 10 shown in FIG. As shown in FIG. 4, the controller 40 is connected to the position sensor 45 described above, and the ON signal and the OFF signal from the position sensor 45 are input to the controller 40. The controller 40 is connected to rotary encoders 46 and 47 and a passage sensor 48. The rotary encoder 46 detects the rotational position of the output shaft of the feed motor 31 and inputs this to the controller 40. The rotary encoder 47 detects the rotational position of the output shaft of the take-up motor 32 or the pulling roller 27 and inputs this to the controller 40. The passing sensor 48 detects that the reference position of the rail 2 being transported by the rail transporting device 3 has passed a predetermined passing position, and inputs this to the controller 40.

  For example, the controller 40 detects the total number of rotations of the feed roller 15 after the new feed reel 4a is mounted based on an input from the rotary encoder 46. The controller 40 detects the current diameter of the delivery reel 4a based on, for example, the total number of revolutions and information on the thickness of the composite tape 4 and the diameter of the new delivery reel 4a stored in advance. Further, the diameter of the delivery reel 4a is determined by detecting how many times the delivery motor 31 has rotated when the remaining tape 6b is wound around the take-up reel 6a by the length of application, and based on the detected rotation angle. It can also be obtained by calculation. For example, when the diameter of the delivery reel 4a falls below a predetermined value, the controller 40 displays that fact on the display device 49. This can prompt the operator to replace the delivery reel 4a.

  The controller 40 detects the position sensor 45, the rotary encoders 46 and 47, and the passage sensor 48 so as to automatically and accurately perform the operation of sequentially and sequentially attaching the double-sided tape pieces 5a to the adherend surface 2a of the rail 2. In response to the input, the pasting motor 14, the feeding motor 31, the winding motor 32, and the cutter actuator 36 are controlled.

  The controller 40 controls the rotational positions of the feed motor 31 and the take-up motor 32 in order to feed and return the composite tape 4 and the remaining tape 6b, thereby controlling the rotational driving force. More specifically, the controller 40 gives the take-up motor 32 a rotational position command that rotates in the feeding direction when the composite tape 4 and the remaining tape 6b are fed, and a predetermined value when stopping the composite tape 4 and the remaining tape 6b. A rotational position command for maintaining the rotational position of is provided. On the other hand, the controller 40 always gives the feed motor 31 a rotational position command having a certain deviation in the returning direction with respect to the rotational position command of the take-up motor 32. Thereby, the feed motor 31 tries to rotate in the returning direction. However, the feed motor 31 is rotated by the take-up motor 32 in the direction opposite to the rotation direction in which it is intended to rotate, or overcomes the rotational driving force of the take-up motor 32 that tries to maintain the rotation position to be stopped. Since the motor rotates in the direction of rotation that it intends to rotate, it becomes an overload state and a load current full of the current limit flows. In this state, the controller 40 variably sets the current limit value of the feed motor 31 according to the traveling direction of the composite tape 4 and the remaining tape 6b. Furthermore, when sending the composite tape 4 and the remaining tape 6b, the current limit value of the delivery motor 31 is variably set depending on whether or not the double-sided tape piece 5a is adhered to the rail 2.

  FIG. 5 is a diagram for explaining the current limit value of the feed motor 31. As shown in FIG. 5, when sending the composite tape 4 and the remaining tape 6b with the double-sided tape piece 5a separated from the rail 2, the controller 40 sets the current limit value of the delivery motor 31 to the first current value. A command is given to the feed motor 31 to set to I1. When returning the composite tape 4 and the remaining tape 6b, the controller 40 gives a command to the feed motor 31 to set the current limit value of the feed motor 31 to the second current value I2. When sending the composite tape 4 and the remaining tape 6b in a state where the double-sided tape piece 5a is in contact with the rail 2, the controller 40 sets the current limit value of the feed motor 31 to the third current value I3. A command is given to 31.

  The first current value I1 is smaller than the second current value I2 and smaller than the third current value I3. The second current value I2 is larger than the third current value I3. That is, the first to third current values I1 to I3 satisfy the relationship I1 <I3 <I2. In this way, the controller 40 changes and sets the current limit value of the delivery motor 31 while giving a rotational position command having a certain deviation in the return direction with respect to the rotational position of the delivery motor 31. Then, a current of a current limiting value flows through the feed motor 31, thereby changing the pulling force (the pulling force in the returning direction or the back tension with respect to the feeding direction) applied to the composite tape 4 and the remaining tape 6 b.

  A limiting mechanism (not shown) for changing the current limit value of the motor is in the final stage of the control system. For this reason, when the rotational driving force is controlled by changing the current limit value as described above and thereby the running of the composite tape 4 and the remaining tape 6b is controlled, the responsiveness of the composite tape 4 and the remaining tape 6b is improved. be able to.

  When the above control is performed, when the composite tape 4 and the remaining tape 6b are sent, the rotational driving force for returning the composite tape 4 and the remaining tape 6b of the feed motor 31 causes the composite tape 4 and the remaining tape 6b of the take-up motor 32 to rotate. It becomes smaller than the rotational driving force that sends As a result, the take-up device 55 pulls out the composite tape 4 from the feed reel 4a by winding the remaining tape 6b, and the feed device 50 applies back tension to the composite tape 4 drawn from the feed reel 4a. .

  Conversely, when the composite tape 4 and the remaining tape 6b are returned, the rotational driving force for returning the composite tape 4 and the remaining tape 6b of the feed motor 31 is greater than the rotational driving force of the take-up motor 32 for feeding the composite tape 4 and the remaining tape 6b. Also grows. Thereby, the feeding device 55 pulls out the remaining tape 6b by winding up the composite tape 4, and the winding device 55 applies a back tension to the remaining tape 6b pulled out from the take-up reel 6a. The traveling direction of the composite tape 4 and the remaining tape 6b can be changed only by adjusting the rotational driving force of the feed motor 31 and the take-up motor 32. Therefore, compared with the mode in which the feeding motor 31 and the take-up motor 32 generate braking torque to apply tension to the composite tape 4 and the remaining tape 6b, the traveling direction of the composite tape 4 and the remaining tape 6b can be changed quickly. It can be carried out.

  In the example of FIG. 5, even when the composite tape 4 and the remaining tape 6b are stopped, a command is given to the delivery motor 31 to set the current limit value of the delivery motor 31 to the first current value I1. At this time, the take-up motor 32 is stopped, and the feed motor 31 is controlled to generate a rotational driving force for returning the composite tape 4 and the remaining tape 6b. Here, the first current value I1 is set to a current value that generates a rotational driving force that balances the resistance of the travel path 30 such as friction. Therefore, a certain tension is applied to the composite tape 4 and the remaining tape 6b. However, the current limit value of the feed motor 31 when stopping the composite tape 4 and the remaining tape 6b may be other values as long as a constant tension can be applied in this way.

  The controller 40 detects the diameter of the delivery reel 4a using the rotary encoder 47, and changes the first to third current values I1 to I3 according to the detected diameter of the delivery reel 4a. May be set. For example, when the feed motor 31 generates a rotational driving force for returning the composite tape 4 and the remaining tape 6b, the more the composite tape 4 is consumed and the diameter of the feed reel 4a becomes smaller, the more the take-up reel 4a is wound. The rotational driving force required for rotating the composite tape 4 against the load on the device 55 side is small. Therefore, when the first to third current values I1 to I3 set when the detected diameter of the delivery reel 4a is the first diameter are the second diameter larger than the first diameter. The current value may be smaller than each current value.

  In addition, when quickness is not required for the change of the running direction of the composite tape 4 and the remaining tape 6b, the feeding device 50 and the winding device 55 generate a braking force, and the feeding motor 31 or the winding motor 32 is in the reverse direction. The rotation direction of the composite tape 4 and the remaining tape 6b may be changed by giving a rotation command to

[Tape application method]
FIG. 6 is a flowchart showing the contents of control of the tape applicator 10 executed by the controller 40 shown in FIG. In order to prepare for executing the processing shown in FIG. 6, a new delivery reel 4a is mounted on the delivery roller 15, and the composite tape 4 pulled out from the delivery reel 4a is guided to the guide rollers 17 to 26 and the pulling roller as described above. 27 is sequentially wound, and its leading end is wound on a take-up reel 6 a mounted on the take-up roller 16. As a result, the composite tape 4 extends linearly between the two adjacent guide rollers along the common tangent line of the two rollers, and is tensioned on the travel path 30 so as not to become loose.

  As shown in FIG. 6, in the state where this preparation is completed, the double-sided tape pieces 5a are cued (steps S1 to S6). First, the cutting device 35 is operated to cut only the double-sided tape 5 of the composite tape 4 between the guide rollers 18 and 19 from above (step S1). Next, the composite tape 4 is fed (step S2), and when the feed amount reaches a predetermined amount, the feed of the composite tape 4 is stopped (step S3). The pulling roller 48 has a constant rotation radius regardless of the diameters of the feed reel and the take-up reel. Therefore, the feed amount can be measured using the rotary encoder 47 of the pulling roller 48. Next, the cutting device 35 is operated again to cut the double-sided tape 5 (step S4). Thereby, one double-sided tape piece 5a having a length corresponding to the predetermined amount is created. Thereafter, each time the cutting device 35 is operated, the double-sided tape pieces 5a are sequentially produced one by one.

  After step S4, it is determined whether or not a prescribed number (three in this embodiment) of double-sided tape pieces 5a has been created (step S5). If the prescribed number has not been reached (S5: No), step S2 is performed. -S4 is executed again. The double-sided tape pieces 5a produced sequentially are formed through the same processing in steps S2 to S4 and have the same size. These double-sided tape pieces 5 a are arranged in a line along the travel route 30 as viewed from the position where the cutter 37 enters on the travel route 30. In the present embodiment, the distance from the position where the cutter 37 enters to the predetermined standby position is about 3 times the length of one double-sided tape piece 5a (that is, the feed amount of the composite tape 4 in step S2). It has doubled. For this reason, at the time of completing the production of the three double-sided tape pieces 5a, the head end of the double-sided tape piece 5a that is first produced and located on the most downstream side is located in the vicinity of the standby position. When the creation of the prescribed number (three in this embodiment) of the double-sided tape pieces 5a is completed in this way (S5: Yes), the positioning of positioning the head end of the double-sided tape piece 5a located on the most downstream side at the standby position is performed. Processing is performed (step S6).

  FIG. 7 is a flowchart showing the contents of the positioning process shown in FIG. FIG. 8 is an operation diagram when positioning the double-sided tape piece 5a. As shown in FIG. 7, in the positioning process, first, it is determined whether or not the input from the position sensor 45 is an ON signal (step S21).

  When the signal is an ON signal (S21: Yes), since the head end of the double-sided tape piece 5a passes through the standby position (see FIG. 8A), the composite tape 4 and the remaining tape 6b are returned (step S22). Then, the input from the position sensor 45 is monitored, and the input from the position sensor 45 is monitored to determine whether or not this input is an off signal (step S23). While the signal is on (S23: No), the composite tape 4 and the remaining tape 6b are kept returned. When the input from the position sensor 45 becomes an OFF signal (S23: Yes), the composite tape 4 and the remaining tape 6b are sent (step S24). Then, the input from the position sensor 45 is monitored to determine whether or not the input is an ON signal (step S25). While the signal is OFF (S25: No), the composite tape 4 and the remaining tape 6b are continuously fed. When the ON signal is received from the position sensor 45 (S25: Yes), the feeding of the composite tape 4 and the remaining tape 6b is stopped (step S26). Thus, by stopping the feeding of the composite tape 4 and the remaining tape 6b when the input from the position sensor 45 is switched from the off signal to the on signal, the head end of the double-sided tape piece 5a located on the most downstream side is stopped. Can be positioned at a predetermined standby position (see FIG. 8C).

  If the input from the position sensor 45 is an off signal in the determination in step S21 (S21: No), the head end of the double-sided tape piece 5a has not reached the standby position (see FIG. 8B). The process proceeds to step S24. Thereafter, the same processing as described above is executed to position the head end of the double-sided tape piece 5a at the standby position (see FIG. 8C).

  Returning to FIG. 2, the processes S <b> 1 to S <b> 6 so far are heads, and this heading is performed at a stage before the rail 2 is transported by the rail transport device 3. The double-sided tape piece 5a located on the most downstream side waits for application to the rail 2 while being positioned at the standby position. In this standby state, the controller 40 monitors the input from the passage sensor 48, and whether or not the reference position of the rail 2 conveyed by the rail conveyance device 3 has passed a predetermined passage position of the rail conveyance path 3a. Is determined (step S7).

  FIG. 9 is an operation diagram when the double-sided tape piece 5 a is attached to the rail 2. When the reference position of the rail 2 passes the passing position of the rail conveyance path 3a (see FIG. 9A), the movable body 12 is moved downward with this as a trigger, and the composite tape 4 and the remaining tape 6b are sent. (Step S8).

  Next, when the movable body 12 moves by a predetermined amount, the movement of the movable body 12 is stopped and the current limit value of the feed motor is switched from the first current value I1 to the third current value I3 (step S9). .

  Here, when the movable body 12 is moved by the predetermined amount, the double-sided tape piece 5a located on the most downstream side accurately comes into contact with the application position where the double-sided tape piece 5a on the adherend surface 2a of the rail 2 is to be attached. (See FIG. 9B). That is, the time required for the movable body 12 to move by the predetermined amount is a value determined according to the design parameters of the tape sticking device 10 and the specifications of the sticking motor 14. The transport speed of the rail 2 is controlled to a predetermined speed by the rail transport device 3, and the distance that the rail 2 is transported within the time is also a predetermined value. Further, the amount of the double-sided tape piece 5a that is positioned on the most downstream side within the time in the state where the current limit value of the feed motor 31 is set to the first current value I1 is also determined. Value. For this reason, when the movement of the movable body 12 and the feeding of the composite tape 4 and the remaining tape 6b are started when the reference position set on the rail 2 passes the predetermined passing position, the head end of the double-sided tape piece 5a is started. Accurately contacts a certain position associated with the reference position on the adherend surface 2 a of the rail 2. In this embodiment, the reference position, the passing position, and the standby position are the time required for the movable body 12 to move until the double-sided tape piece 5a is brought into contact with the adherend surface 2a of the rail, and the transport distance of the rail 2 within the time. Depending on the feed amount of the composite tape 4 and the remaining tape 6b, the position where the head end of the double-sided tape piece 5a contacts and the position where the double-sided tape piece 5a should be attached on the adherend surface 2a of the rail 2 are determined. It is set to match. Thereby, the said effect | action (refer FIG.9 (b)) is show | played.

  When the double-sided tape piece 5a comes into contact with the adherend surface 2a of the rail 2, the one surface of the double-sided tape piece 5a is held by the peeling tape 6, and the opposite surface is held by the adherend surface 2a of the rail. The travel path 30 extends in the vicinity of the outer peripheral surface of the guide roller 21 so that the front direction, which is the conveyance direction of the rail 2, is on the downstream side. Then, the composite tape 4 is dragged downstream by the rail 2. On the other hand, when the double-sided tape piece 5a is in contact with the rail 2, the tape applicator 10 sends the composite tape 4 and the remaining tape 6b, and generates a rotational driving force for returning the composite tape 4 and the remaining tape 6b. The current limit value of the sending motor 31 to be set is set to a third current value I3 which is a larger value than when sending in a non-contact manner. Therefore, a larger back tension is applied to the composite tape 4 and the remaining tape 6b than when the composite tape 4 and the remaining tape 6b are fed in a non-contact manner. Accordingly, the composite tape 4 and the remaining tape 6b can be fed while suitably resisting the forward pulling (ie, downstream) by the rail 2, and the double-sided tape piece 5a is suitably removed after coming into contact with the rail 2. Can be peeled off.

  Furthermore, in this embodiment, before the double-sided tape piece 5a contacts the rail 2, the composite tape 4 and the remaining tape 6b start to be fed. As described above, the composite tape 4 and the remaining tape 6b are run in advance before contact with the rail 2, so that the tensile force from the rail 2 acting on the composite tape 4 and the remaining tape 6b immediately after contacting the rail 2 is reduced. The load can be reduced.

  Then, when the composite tape 4 and the remaining tape 6b are fed by substantially the same amount as the length of the double-sided tape piece 5a, that is, when the tail end of the double-sided tape piece 5a comes into contact with the adherend surface 2a of the rail 2 (FIG. 9 (c). )), The movable body 12 is moved up, and the feeding of the composite tape 4 and the remaining tape 6b is stopped (step S10). Then, when the movable body 12 is retracted to the original position (see FIG. 9D), the movable body 12 is stopped (step S11), and whether or not to continue the operation of attaching the double-sided tape piece 5a to the rail 2 is determined. Judgment is made (step S12). When the operation of attaching the double-sided tape piece 5a is finished (S12: No), the processing is finished. When the operation of affixing the double-sided tape piece 5a to the rail 2 is continued (S12: Yes), a positioning process for positioning the head end of the double-sided tape piece 5a to be affixed to the rail 2 next to the standby position is executed (step) S13).

  This positioning process (S13) is also executed in the same manner as the positioning process (S6) described above (see FIGS. 7 and 8). Here, the feeding of the composite tape 4 and the remaining tape 6b after positioning the head end of a certain double-sided tape piece 5a until positioning the head end of the double-sided tape piece 5a to be attached to the rail 2 next time is performed. The amount is the feed amount corresponding to the running distance during which the movable body 12 moves downward, and the length of the double-sided tape piece 5a that is necessary for attaching the adhesive tape piece 5a to the adherend surface 2a of the rail 2. Although the influence is reduced by the control of the current limit value of the feed motor 31, the feed amount to the downstream side due to the pulling of the rail 2 is included.

  On the other hand, the head end of the double-sided tape piece 5a to be attached next to the rail 2 is located at the same position as the tail end of the double-sided tape piece 5a peeled off from the peeling tape 6 by being attached to the rail 2. Therefore, the probability that the head end of the leading double-sided tape piece 5a held by the peeling tape 6 is located downstream of the standby position as shown in FIG. Is expensive.

  In the present embodiment, in the positioning process shown in FIG. 7 and FIG. 8, even if the head end of the double-sided tape piece 5a is located downstream from the standby position, the feeding device returns the composite tape 4 and the remaining tape 6b. In addition, since the winding device can be controlled, the head end of the double-sided tape piece 5a can be returned to the standby position.

  Next, when the head end of the double-sided tape piece 5a to be attached to the rail 2 is positioned, the cutting device 35 is operated to cut the double-sided tape 5 out of the composite tape 4 to create the double-sided tape piece 5a (step S14). . As described above, the distance from the position where the cutter 37 enters along the travel route 30 to the standby position is three times the length required for the double-sided tape piece 5a. On the other hand, when the attachment to the rail 2 is finished, the number of double-sided tape pieces 5 a that is one less than the specified number (two in the present embodiment) remains on the traveling path 30 while being held by the release tape 6. . When the head end of the remaining double-sided tape piece 5a is positioned at the standby position, the distance from the tail end of the most downstream double-sided tape piece 5a to the position where the cutter 37 enters is the length required for the double-sided tape piece 5a. Will be equal. For this reason, a single double-sided tape piece 5a having a required length is newly created by merely operating the cutting device 35 with the head end of the double-sided tape piece 5a located on the most downstream side being positioned at the standby position. be able to.

  After the head end of the double-sided tape piece 5a located on the most downstream side is thus positioned at the standby position and the prescribed number (three in this embodiment) of double-sided tape pieces 5a has been created, the process returns to step S7. The input from the passage sensor 48 is monitored to determine whether or not the reference position of the rail 2 has passed a predetermined passage position of the rail transport path 3a. Thereafter, the above process is repeated until the operation of attaching the double-sided tape piece 5a to the rail 2 is completed.

  As described above, the feeding device 50 and the winding device 55 can quickly change the traveling direction of the composite tape 4 and the remaining tape 6b, so that the head end of the double-sided tape piece 5a can be quickly moved to the standby position. Can be positioned. For this reason, it is possible to prevent the inconvenience that the next reference position passes the passing position before the positioning and the double-sided tape piece 5a are completed.

  As described above, according to the tape applying apparatus 10 according to the present embodiment, even when the rail 2 is in the process of transporting, the double-sided tape piece 5a is peeled off from the release tape 6 and applied to the adherend surface 2a of the rail 2. Can be pasted accurately at the position. Thereby, the production efficiency of the solar panel in the production facility 1 improves compared with the form which stops conveyance of the rail 2 whenever the double-sided tape piece 5a is affixed.

(Second Embodiment)
FIG. 10 is an enlarged view of a main part of the tape applying device 110 according to the second embodiment of the present invention. Elements that are the same as or equivalent to those in the above embodiment are given the same reference numerals, and redundant descriptions are omitted. As shown in FIG. 10, the affixing portion 128 of the present embodiment includes guide rollers 19 to 22 as the guide rollers that form the travel route 130, as in the first embodiment. The movable body 12 is provided with a guide plate 161 adjacent to the guide roller 21. The lower surface of the guide plate 161 extends from the outer peripheral surface of the guide roller 21 forward and downward along a common lower tangent line between the outer peripheral surface of the guide roller 20 and the outer peripheral surface of the guide roller 21. As a result, the composite tape 4 and the remaining tape 6b are wound around the outer peripheral surfaces of the guide rollers 19 to 21 in order, and then drawn out forward and downward along the lower surface of the guide plate 161, and at an acute angle at the front end of the guide plate 161. It is folded and wound around the outer peripheral surface of the guide roller 22 from the rear side.

  In this way, the double-sided tape piece 5a maintains the state held by the peeling tape 6 when it is fed from the vicinity of the outer peripheral surface of the guide roller 21 along the lower surface of the guide plate 161, but at the front end of the guide plate. When it reaches, it cannot be folded at an acute angle toward the guide roller 22 together with the peeling tape 6, and is peeled off from the peeling tape 6 and sent forward.

  The affixing portion 128 is provided with a pressing device 162 that presses the double-sided tape piece 5a fed from the front end of the guide plate 161 downward from the upper side, in front of the front end of the guide plate 161. The pressing device 162 includes an air cylinder 163, and the air cylinder has a rod that can be moved up and down. A roller 164 is attached to the lower end of the rod, and this roller 164 presses the double-sided tape piece 5a fed from the guide plate 161 toward the rail 2 from above. Thereby, after the head end of the double-sided tape piece 5a comes into contact with the rail 2 in the process of being conveyed by the rail conveying device 3, the double-sided tape piece 5a is peeled from the peeling tape 6 by feeding the composite tape 4 and the remaining tape 6b. However, it can be satisfactorily attached to the rail 2.

  The embodiments of the present invention have been described so far, but the above configuration can be changed as appropriate without departing from the scope of the present invention.

  The tape sticking device of the present invention is useful as a sticking device for sticking a double-sided tape piece to a workpiece in the process of conveyance.

The controller intermittently sends the composite tape and the remaining tape, thereby creating the double-sided tape piece, positioning the double-sided tape piece, and attaching the double-sided tape piece to a work, and the double-sided tape. The feeding device and the winding device are controlled so that the piece is attached to the workpiece by feeding the composite tape and the remaining tape, and the double-sided tape piece is positioned to return the composite tape and the remaining tape. Configured to control the cutting device, the delivery device, and the take-up device so as to be sent after
The controller gives a command to generate a rotational driving force for feeding the composite tape and the remaining tape to the winding motor and a command to generate a rotational driving force to return the composite tape and the remaining tape to the feeding motor. ,
When feeding the composite tape and the remaining tape, the winding motor is configured so that a rotational driving force for feeding the composite tape and the remaining tape of the feeding motor is smaller than a rotational driving force for feeding the composite tape and the remaining tape of the winding motor. Giving commands to the motor and the delivery motor, and
When the composite tape and the remaining tape are sent in a state where the double-sided tape piece is not in contact with the workpiece, a command is given to the delivery motor so that the current limit value of the delivery motor becomes the first current value, and the double-sided tape piece When the composite tape and the remaining tape are fed in contact with the workpiece, a command is given to the feed motor so that the current limit value of the feed motor is set to a third current value larger than the first current value. is configured, tape applying apparatus.
