Description

Technical Field

[0001] This invention relates to a conveying device. Background Technology

[0002] In the past, there have been technologies for suppressing the serpentine movement of long components in conveying devices. For example, in Patent Document 1, the shape or material of the support member of the stripping roller was studied in order to suppress serpentine movement.

[0003] Patent Document 1: Japanese Patent Application Publication No. 2017-206344 Summary of the Invention

[0004] However, completely eliminating serpentine behavior is difficult.

[0005] The present invention can be implemented in the following ways.

[0006] (1) According to one aspect of the present invention, a conveying device is provided for conveying a long component along a conveying direction. The conveying device includes: a movable clamp that conveys the long component by moving it along the conveying direction while clamping it; a first sensor disposed upstream of the movable clamp in the conveying direction and detecting an offset in the width direction of the long component; a cutting blade disposed downstream of the movable clamp in the conveying direction; and a control unit that performs the following first control: using the first sensor to determine a serpentine section in the long component where the offset occurs, and causing the cutting blade to cut the long component at both the downstream end and the upstream end of the serpentine range containing the serpentine section. According to this method, by cutting the serpentine range containing the serpentine section, the serpentine section can be removed. By not using the removed serpentine section in the product, product defects caused by the serpentine section can be prevented.

[0007] (2) In the conveying device described above, the device may include: a second sensor disposed upstream of the movable clamp in the conveying direction, which detects the adhesive tape on the long component; and a fixing clamp located between the movable clamp and the cutting blade, which fixes the long component at least during the period when the cutting blade cuts the long component. When the second sensor detects the adhesive tape, the control unit controls the conveying of the long component to a position where the adhesive tape does not overlap with the first clamping position of the movable clamp, and to a position where the adhesive tape does not overlap with the second clamping position of the fixing clamp. If the adhesive tape is clamped by the movable clamp, adhesive material may adhere to the movable clamp, resulting in a decrease in the quality of the long component. The same applies to the fixing clamp. Therefore, according to this method, clamping the adhesive tape with both the movable and fixing clamps can be avoided. Thus, a decrease in the quality of the long component can be prevented.

[0008] (3) In the conveying device of the above manner, when the adhesive tape is located downstream of the serpentine section and the interval between the adhesive tape and the serpentine section is a predetermined first reference length or more, the control unit performs the first control, in which the cutting blade cuts the long component at the downstream end and the upstream end of the serpentine section respectively. When the adhesive tape is located downstream of the serpentine section and the interval is shorter than the first reference length, the control unit moves the downstream end of the adhesive tape to the first reference length. A second control is performed to transport the long component at a first position upstream of the clamping position in the conveying direction. Following this second control, a third control is performed to transport the long component by moving the downstream end of the adhesive tape to the second position upstream of the clamping position in the conveying direction. Following this third control, a fourth control is performed to transport the long component by moving it to a third position where cutting based on the cutting blade is performed at the upstream end of the serpentine section without cutting at the downstream end of the serpentine section. According to this method, by cutting the long component at both the upstream and downstream ends of the serpentine section in the first control, the length of discarded long components can be suppressed. Therefore, manufacturing costs can be reduced. Furthermore, by setting the first reference length as the product length, in cases where product components cannot be cut, by continuously discarding the adhesive tape and the serpentine section in the fourth control, the cutting process at the downstream end of the serpentine section can be omitted, simplifying control.

[0009] (4) In the conveying device described above, when the control unit performs the first control if the adhesive tape is located upstream of the serpentine section and the determined length from the downstream end of the serpentine section to the downstream end of the adhesive tape is greater than or equal to a predetermined second reference length, the first control causes the cutting blade to cut the long component at both the downstream end and the upstream end of the serpentine section. When the adhesive tape is located upstream of the serpentine section and the determined length is shorter than the predetermined second reference length, the control unit performs... A fifth control is performed to transport the long component by moving the downstream end of the adhesive tape to a first position upstream of the first clamping position in the transport direction, instead of moving it to a third position where cutting is performed based on the cutting blade at the upstream end of the serpentine section. Following this fifth control, a sixth control is performed to transport the long component by moving the downstream end of the adhesive tape to a second position upstream of the second clamping position in the transport direction. Following this sixth control, a seventh control is performed to transport the long component to the third position. According to this method, by cutting the long component at both the upstream and downstream ends of the serpentine section in the first control, the length of discarded long components can be suppressed. Therefore, manufacturing costs can be reduced. Furthermore, by setting the second reference length to the length of the adhesive tape held by the movable clamp when the downstream end of the snake section is to be cut off, the fifth control is performed when the adhesive tape is held by the movable clamp when the downstream end of the snake section is to be cut off. This prioritizes preventing the adhesive tape from being held by the movable clamp over cutting off the downstream end of the snake section, thereby preventing the quality degradation of long-sized parts.

[0010] (5) In the conveying device of the above manner, an indentation roller may be provided, which is disposed on the upstream side of the conveying direction compared with the cutting blade, and indents are applied to the long component.

[0011] The present invention can also be implemented in various other ways besides those described above. For example, it can be implemented as a conveying method for conveying long-sized components, an apparatus for cutting long-sized components, and a control method for an apparatus for conveying long-sized components.

[0017] A. Implementation method:

[0018] A1. Structure of the conveying device:

[0019] Figure 1 This is a diagram showing the schematic structure of the conveying device 1 that transports and cuts paper 10, which is a long component. (See diagram for reference.) Figure 1 As shown, the conveying device 1 includes a first sensor 30, an indentation roller 40, a second sensor 50, a movable clamp 60, a fixed clamp 70, a cutting blade 80, and a control unit 90. In this embodiment, a roll of paper 10 is used as a long component. After the paper 10 is cut to the desired length by the cutting blade 80, it is inserted into the product 20, which has an internal space.

[0020] In this embodiment, product 20 is a motor stator with slots. In this embodiment, paper 10 is insulating paper inserted into the slots. By placing insulating paper 10 between the conductive segments inserted into the slots and the slots, the segments are insulated from the slots.

[0021] The control unit 90 is configured as a computer with a processor 91 and a memory 92 connected via a bus (not shown). In this embodiment, the control unit 90 is configured as a programmable logic controller (PLC). The control unit 90 is communicatively connected to the first sensor 30, the second sensor 50, the movable clamp 60, the fixed clamp 70, and the cutting blade 80. Furthermore, the control unit 90 controls the movable clamp 60 and other components.

[0022] The first sensor 30, the indentation roller 40, the second sensor 50, the movable clamp 60, the fixed clamp 70, and the cutting blade 80 are arranged in this order from upstream to downstream along the conveying path RU in the conveying direction of the paper 10.

[0023] The first sensor 30 is a sensor for detecting the offset in the width direction of the paper 10. In this embodiment, the first sensor 30 is configured to include a camera. The camera is positioned at least to capture images of one end of the paper 10 in the width direction. Furthermore, the offset in the width direction of the paper 10 is detected by utilizing the offset between the position of the end of the paper 10 reflected in the image captured by the camera and the target position in the image. In this embodiment, the image signal captured by the first sensor 30 is sent to the control unit 90. Furthermore, the structure of the first sensor 30 is not limited to a camera; for example, it may also include a light interruptor.

[0024] The creasing roller 40 is a roller used to imprint creases on the paper 10. In this embodiment, the creasing roller 40 includes a pair of rollers. At least one of the rollers has a protrusion on its surface. Furthermore, by pressing the protrusion on the roller surface onto the paper 10 held by the pair of rollers, a crease is applied to the paper 10 along its length. In addition, the crease applied to the paper 10 corresponds to the shape of the groove. By applying a crease to the paper 10, the paper 10 bends at the crease, thus allowing the paper 10 to be easily inserted into the product 20 along the shape of the groove.

[0025] The second sensor 50 is a sensor used to detect the bonding tape 12, which is an adhesive tape, on the paper 10. The second sensor 50 detects the color of the paper 10 being conveyed along the conveying path RU and sends a detection signal to the control unit 90.

[0026] The movable clamp 60 has a pair of clamping parts that clamp and fix the paper 10. Furthermore, the movable clamp 60 clamps the paper 10 at a first position PO1 and moves to a target position POp while clamped. Thus, the paper 10 is conveyed towards the cutting blade 80 only for a target length Lp between the first position PO1 and the target position POp. The position on the conveying path RU where the movable clamp 60 clamps the paper is called the first clamping position REm. Here, the first clamping position REm has a width in the conveying direction. Specifically, the width of the first clamping position REm is the same as the width of the pair of clamping parts in the conveying direction. Figure 1 In the diagram, the first clamping position REm is indicated by a crosshair.

[0027] The fixing clamp 70 has a pair of clamping portions that clamp and secure the paper 10. The fixing clamp 70 secures the paper 10 at least during the period when the cutting blade 80 cuts the paper 10. This allows for stable cutting of the paper 10. The cutting blade 80 cuts the paper 10. The cut paper 10 is inserted into the product 20 disposed below the cutting blade 80. The position on the transport path RU where the fixing clamp 70 clamps the paper is called the second clamping position REf. Here, the second clamping position REf has a width in the transport direction. Specifically, the width of the second clamping position REf is the same as the width of the pair of clamping portions in the transport direction. Figure 1 In the diagram, the second clamping position REf is indicated by a crosshair.

[0028] The conveying device 1 repeatedly performs the conveying process of paper 10 based on the movable clamp 60 and the cutting process based on the cutting blade 80. Specifically, after the paper 10 is conveyed to the target length Lp by the movable clamp 60, the paper 10, which is fixed by the fixed clamp 70, is cut by the cutting blade 80. The movable clamp 60 at the target position POp returns to the first position PO1 and clamps the paper 10 again. The paper 10 is conveyed intermittently by repeatedly clamping and moving by the movable clamp 60.

[0029] By repeatedly performing the conveying and cutting processes, the roll of paper 10 is cut into pieces of paper 10 with the same length as the target length Lp. Furthermore, the target length Lp can be a constant distance or it can vary each time it is cut. That is, the lengths of the paper 10 inserted into the product 20 can be the same or different.

[0030] During the conveying process, the paper 10 sometimes shifts in the width direction. If the paper 10 shifts in the width direction, the indentation made by the indentation roller 40 shifts from the target position. Therefore, the cut paper 10 is inserted into the slot in a state that has shifted from the target position. Subsequently, if the paper 10, which serves as insulation paper, is inserted with the indentation shifted from the target position, the insulation between the slot and the segment is compromised. Therefore, in the conveying process described later, in order to prevent the portion of the paper 10 that has shifted in the width direction from being inserted into the product 20, it is cut off and discarded. Thus, only the paper 10 with the indentation pressed to the target position is inserted into the slot, thereby ensuring the insulation between the slot and the segment.

[0031] In the following description, the offset in the width direction of paper 10 is referred to as "serpentine", and the range of offset in the width direction of paper 10 is referred to as "serpentine range". Figure 1 In the diagram, the serpentine section 14 is indicated by a shaded line. The upstream and downstream ends of the serpentine section 14 can be detected by the detection signal from the first sensor 30. Furthermore, in... Figure 1 Although not shown in the diagram, the conveying device 1 includes a snake control mechanism for correcting snake movement. In the event of snake movement, the snake control mechanism corrects the snake movement, thus preventing the length of the snake movement interval from becoming excessively long. However, if the paper 10 in the conveying device 1 is improperly positioned, the snake movement cannot be eliminated by the snake control mechanism. In this case, a worker must reset the paper 10 in the conveying device 1. Furthermore, in this embodiment, the paper 10 is conveyed at a constant speed via a conveying roller (not shown) within the conveying path RU, which includes the first sensor 30 and the creasing roller 40.

[0032] When a roll of paper 10 reaches its end during the repeated conveying and cutting processes, the currently conveyed roll of paper 10 is connected to a new roll of paper 10 via a bonding tape 12. The bonding tape 12 is a tape coated with an adhesive substance. Figure 1 In this diagram, the currently conveyed roll of paper 10 is shown as the first sheet 10A, and the new roll of paper 10 is shown as the second sheet 10B. Furthermore, in... Figure 1 In the diagram, the portion connected by the bonding tape 12 is indicated by a single shaded line.

[0033] When the adhesive tape 12 is held by the movable clamp 60, the adhesive material of the adhesive tape 12 may sometimes seep out and adhere to the movable clamp 60. If the adhesive material adheres to the movable clamp 60, for example, when paper 10 is held by the movable clamp 60 with the adhesive material attached, the adhesive material may adhere to the held paper 10, which may lead to a decrease in the quality of the paper 10. In addition, the adhesion of the adhesive material may occur not only in the movable clamp 60, but also in the fixed clamp 70.

[0034] In the control performed by the control unit 90, which will be described next, the following design is implemented to prevent the snake section 14 from inserting into the product 20 and to prevent the adhesive material from adhering to the movable clamp 60 and the fixed clamp 70.

[0035] A2. Control Summary:

[0036] Figure 2 and Figure 3 It is a diagram used to illustrate the control overview. Figure 2 This is a diagram used to illustrate conventional control and control A.

[0037] The conventional control is performed with the bonding tape 12 and the serpentine section 14 fully separated. In the conventional control, a first control is performed where the upstream end and the downstream end of the serpentine range containing the serpentine section 14 in the transport direction are cut off by the cutting blade 80. Afterwards, the cut-off serpentine section 14 is discarded into the waste bin 22 instead of being inserted into the product 20. This prevents the insertion of a defective serpentine section 14 into the product 20. Furthermore, in this embodiment, the paper 10 is cut at both the upstream and downstream ends of the serpentine section 14 during the first control. This suppresses the length of the discarded portion of the paper 10. Additionally, the upstream end of the serpentine section 14 corresponds to a position within a range up to the upstream side, encompassing the upstream end and extending only 10% of the length of the serpentine section 14 from the upstream end. Similarly, the downstream end of the serpentine section 14 corresponds to a position within a range up to the downstream side, encompassing the downstream end and extending only 10% of the length of the serpentine section 14 from the downstream end.

[0038] Furthermore, in conventional control, the bonding tape 12 is prevented from being clamped by the movable clamp 60 and the fixed clamp 70. This avoids quality degradation caused by the movable clamp 60 and the fixed clamp 70 clamping the bonding tape 12. Additionally, the control preventing the bonding tape 12 from being clamped by the movable clamp 60 and the fixed clamp 70 is also performed in controls A, B, and C described later.

[0039] Specifically, in order to prevent the bonding tape 12 from being clamped by the movable clamp 60 and the fixed clamp 70, the paper 10 is conveyed to a position where the bonding tape 12 does not overlap with the first clamping position REm of the movable clamp, and the paper 10 is conveyed to a position where the bonding tape 12 does not overlap with the second clamping position REf of the fixed clamp 70.

[0040] In this embodiment, a second control is performed to feed the paper 10 by moving the downstream end of the bonding tape 12 to a first position PO1 upstream of the first clamping position REm, and a third control is performed to feed the paper 10 by moving the downstream end of the bonding tape 12 to a second position PO2 upstream of the second clamping position REf. Here, in this embodiment, when the downstream end of the bonding tape 12 is at the first position PO1, the first position PO1 is set to the position closest to the movable clamp 60 within the range where the bonding tape 12 is not clamped by the movable clamp 60. In this embodiment, when the downstream end of the bonding tape 12 is at the second position PO2, the second position PO2 is set to the position closest to the fixed clamp 70 within the range where the bonding tape 12 is not clamped by the fixed clamp 70.

[0041] use Figure 2 This section provides a detailed explanation of conventional controls. Figure 2 In conventional control, an example is shown where the joining tape 12 and the serpentine section 14 are fully separated, and the joining tape 12 is located downstream of the serpentine section 14 in the conveying direction.

[0042] First, such as Figure 2 As shown in the conventional control process (a), the paper 10 is conveyed to the downstream end of the bonding tape 12 until it moves to the first position PO1. Furthermore, since the movable clamp 60 has an upper limit on its travel distance, in process (a), specifically, the paper 10 is conveyed to the downstream end of the bonding tape 12 until it moves to the first position PO1 by repeating the conveying and cutting processes multiple times. Afterwards, the paper 10 is cut at the third position PO3. The same applies to the processes described below. That is, unless otherwise stated, the combination of the conveying and cutting processes is performed more than once in each process. In the following description, for the sake of simplicity, descriptions of parts where the conveying and cutting processes are performed more than once, or parts where cutting occurs after the final conveying in each process, are sometimes omitted.

[0043] Next, as shown in the conventionally controlled process (b), the paper 10 is conveyed to the downstream end of the bonding tape 12 until it reaches position PO2. Next, as shown in process (c), the paper 10 is conveyed to the upstream end of the bonding tape 12 at position PO3, where it is cut by the cutting blade 80. Figure 2 In the routine control process from process (a) to process (c), the length of the cut paper 10 is not the product length for product 20 or includes the joining tape 12, therefore the cut paper 10 is discarded into waste bin 22. Figure 1 )middle.

[0044] exist Figure 2 Under normal control conditions, the bonding tape 12 and the serpentine section 14 are fully separated. Therefore, in the normally controlled step (d), the target length Lp is set to the product length, and the paper 10 cut to the product length is inserted into the product 20. Then, if the serpentine section 14 approaches the cutting blade 80, as shown in step (e), the paper 10 is conveyed to the downstream end of the serpentine section 14 until it moves to the third position PO3. Next, as shown in step (f), it is conveyed to the upstream end of the serpentine section 14 until it moves to the third position PO3. Figure 2 In the routine control process from process (e) to process (f), the length of the cut paper 10 is not the product length or includes the serpentine section 14, so the cut paper 10 is discarded into the waste bin 22.

[0045] In the above Figure 2 In the conventional control, an example is shown where the joining tape 12 is located downstream of the serpentine section 14 in the conveying direction. However, the same control is performed when the joining tape 12 is located upstream of the serpentine section 14 in the conveying direction. In this case, after cutting at the upstream and downstream ends of the serpentine section 14, the joining tape 12 is cut to avoid being clamped by the movable clamp 60 and the fixed clamp 70. In the following description, the conventional control where the joining tape 12 is located downstream of the serpentine section 14 is referred to as "first conventional control," and the conventional control where the joining tape 12 is located upstream of the serpentine section 14 is referred to as "second conventional control."

[0046] As described above, when the serpentine section 14 and the joining tape 12 are sufficiently separated, it is possible to simultaneously achieve cutting at both the upstream and downstream ends of the serpentine section 14 and prevent the joining tape 12 from being clamped by the movable clamp 60 and the fixed clamp 70. On the other hand, when the serpentine section 14 and the joining tape 12 are not sufficiently separated, it is impossible to simultaneously achieve cutting at both the upstream and downstream ends of the serpentine section 14 and prevent the joining tape 12 from being clamped by the movable clamp 60 and the fixed clamp 70. Therefore, based on the relative positional relationship between the serpentine section 14 and the joining tape 12, three controls—control A, control B, and control C—are implemented.

[0047] like Figure 2 As shown in Control A, Control A is a control performed when the joining tape 12 is located downstream in the conveying direction compared to the serpentine section 14. In this case, firstly, as... Figure 2 As shown in step (a) of control A, the paper 10 is conveyed to the downstream end of the bonding tape 12 until it moves to position PO1. Next, as shown in step (b), the paper 10 is conveyed to the downstream end of the bonding tape 12 until it moves to position PO2. Next, as shown in step (c), the paper 10 is conveyed to the upstream end of the bonding tape 12 until it moves to position PO3.

[0048] Under the control of A, Figure 2 In the state of process (c) of control A, the serpentine section 14 has approached the cutting blade 80. Therefore, as shown in the next process (d), the feeding will not stop at the position where the downstream end of the serpentine section 14 is aligned with the third position PO3, and the feeding of the paper 10 will continue. Moreover, as shown in process (e) of control A, the paper 10 is fed until it moves to the third position PO3 at the upstream end of the serpentine section 14.

[0049] As described above, under control A, the paper 10 of the product length cannot be cut between the bonding tape 12 and the serpentine section 14, therefore no cutting is performed at the downstream end of the serpentine section 14. Figure 2 In the process from step (a) to step (e) of control A, the length of the cut paper 10 is not the product length or includes either the joining tape 12 and the serpentine section 14, so the cut paper 10 is discarded into the waste bin 22.

[0050] The choice between conventional control and control A is determined based on whether the interval Id between the bonding tape 12 and the serpentine section 14 is greater than or equal to the first reference length Ls1. That is, conventional control is performed when the interval Id is greater than or equal to the first reference length Ls1. Control A is performed when the interval Id is less than the first reference length Ls1. Furthermore, when the bonding tape 12 is located downstream of the serpentine section 14, the interval Id between the bonding tape 12 and the serpentine section 14 is the length of the paper 10 from the upstream end of the bonding tape 12 to the downstream end of the serpentine section 14. In this embodiment, the first reference length Ls1 is set to the length of the paper 10 that can be cut to the length of one product between the bonding tape 12 and the serpentine section 14. The first reference length Ls1 can be determined in advance through experiments, etc.

[0051] Figure 3 This is a diagram used to illustrate control B and control C. For example... Figure 3 As shown, controls B and C are performed when the joining tape 12 is located upstream in the conveying direction compared to the serpentine section 14. Which of controls B or C is performed is determined based on whether the determined length Ld of the paper 10 from the downstream end of the serpentine section 14 to the downstream end of the joining tape 12 is greater than or equal to the second reference length Ls2 described later. The second reference length Ls2 will be described later.

[0052] Control B is performed when the determined length Ld is greater than or equal to the second reference length Ls2. In control B, such as... Figure 3 As shown in step (a) of control B, firstly, paper 10 is conveyed to the downstream end of the serpentine section 14 until it moves to position 3 PO3. Next, as shown in step (b), paper 10 is conveyed to the upstream end of the serpentine section 14 until it moves to position 3 PO3. Next, as shown in step (c), paper 10 is conveyed to the downstream end of the bonding tape 12 until it moves to position 1 PO1. Next, as shown in step (d), paper 10 is conveyed to the downstream end of the bonding tape 12 until it moves to position 2 PO2. Next, as shown in step (e), paper 10 is conveyed to the upstream end of the bonding tape 12 until it moves to position 3 PO3. Figure 3 In the process from step (a) to step (e) of control B, the length of the cut paper 10 is not the product length or includes either the joining tape 12 and the serpentine section 14, so the cut paper 10 is discarded into the waste bin 22.

[0053] Control C is performed when the determined length Ld is less than the second reference length Ls2. For example... Figure 3 As shown in process (a) of control C, firstly, the paper 10 is conveyed to the downstream end of the bonding tape 12 until it moves to position PO1. From Figure 3A comparison of process (c) of control B and process (a) of control C reveals that, under control C where the determined length Ld is less than the second reference length Ls2, assuming the tape 12 is conveyed to the third position PO3 at the downstream end of the serpentine section 14, the joining tape 12 is clamped by the movable clamp 60. Therefore, under control C, it is preferable to avoid the joining tape 12 being clamped by the movable clamp 60 compared to cutting at the upstream end of the serpentine section 14.

[0054] In progress Figure 3 Following step (a) of control C, as shown in step (b), the paper 10 is conveyed to the downstream end of the bonding tape 12 until it moves to position PO2. Next, as shown in step (c), the paper 10 is conveyed to the upstream end of the bonding tape 12 until it moves to position PO3. Figure 3 In the process from step (a) to step (c) of control C, the length of the cut paper 10 is not the product length or includes either the joining tape 12 and the serpentine section 14, so the cut paper 10 is discarded into the waste bin 22.

[0055] In this embodiment, such as Figure 1 As shown, the second reference length Ls2 is set as the length of the transport path RU from the first position PO1 to the third position PO3.

[0056] As above, it will be used as follows Figure 2 As described in steps (d) and (e) of control A, the control of feeding paper 10 in a manner that does not involve cutting at the downstream end of the serpentine section 14 while moving the upstream end of the serpentine section 14 to the third position PO3 is also referred to as the fourth control. This will be used as described in the following steps. Figure 3 As described in step (a) of control C, the control that moves the paper 10 to position 1, PO1, instead of moving it to position 3, PO3, at the upstream end of the serpentine section 14 is also called the 5th control. Furthermore, the control that moves the paper 10 to position 2, PO2, at the downstream end of the detached tape 12, as described in step (b) of control C, is also called the 6th control. And the control that moves the paper 10 to position 3, PO3, at the upstream end of the detached tape 12, as described in step (c) of control C, is also called the 7th control.

[0057] A3. Detailed Control Information:

[0058] Figure 4 This is the first flowchart illustrating the steps involved in implementing the conveying method. Figure 5This is the second flowchart illustrating the steps of the conveying process. During the operation of the conveying device 1, the control unit 90 repeatedly executes the conveying process. The control unit 90 performs the conveying process by executing a control program (not shown) stored in the memory 92.

[0059] like Figure 1 As shown, in the structure of the conveying device 1 of this embodiment, the first sensor 30 is located upstream of the second sensor 50. Therefore, when a serpentine section 14 exists near the bonding tape 12, the serpentine section 14 is detected by the first sensor 30 before the bonding tape 12 is detected by the second sensor 50.

[0060] In step S10, the control unit 90 determines whether serpentine movement is detected during the period when the paper 10 is conveyed only to the target length Lp via the movable clamp 60. Specifically, the control unit 90 uses the image signal sent from the first sensor 30 to determine whether serpentine movement is detected. If it is determined in step S10 that no serpentine movement in the interval 14 is detected, the control unit 90 terminates the processing flow.

[0061] If serpentine movement is detected in step S10, in step S12, the control unit 90 uses the first sensor 30 to determine the serpentine section 14. Specifically, the control unit 90 uses the moment when serpentine movement is detected (i.e., the moment when the downstream end of the serpentine section 14 is detected) obtained from the image signal sent from the first sensor 30 to calculate the length of the paper 10 from the downstream end of the serpentine section 14 to the third position PO3. Furthermore, the control unit 90 uses the time from the moment serpentine movement is detected to the moment when serpentine movement is no longer detected and the paper 10's conveying speed to calculate the length of the serpentine section 14.

[0062] In step S14, the control unit 90 determines whether the length of the serpentine section 14 is above a preset abnormal value. If it is determined that the length of the serpentine section 14 is above an abnormal value, the setting state of the paper 10 in the conveying device 1 may be abnormal. Therefore, in step S16, the control unit 90 notifies of an error and terminates the processing flow.

[0063] In step S14, if it is determined that the length of the serpentine interval 14 is not above an abnormal value, in step S18, the control unit 90 uses the detection signal of the second sensor 50 to determine whether the bonding tape 12 is detected within a preset first time TD1 period from the detection of the serpentine interval 14 in step S10.

[0064] The color of the paper 10 with the adhesive tape 12 attached is different from the color of the paper 10 without the adhesive tape 12 attached. Therefore, the adhesive tape 12 can be detected based on the detection value of the second sensor 50. When the detection value of the second sensor 50 corresponds to the color of the paper 10 with the adhesive tape 12 attached, the control unit 90 determines that the adhesive tape 12 has been detected. On the other hand, when the detection value of the second sensor 50 corresponds to the color of the paper 10 without the adhesive tape 12 attached, the control unit 90 determines that the adhesive tape 12 has not been detected.

[0065] (First routine control)

[0066] In step S18, the determination that the bonding tape 12 is detected during the first time interval TD1 corresponds to the first conventional control described above. The first time interval TD1 can be predetermined through experiments using paper 10 with the bonding tape 12 located downstream of the serpentine section 14 and the interval Id between the bonding tape 12 and the serpentine section 14 being the first reference length Ls1. The first time interval TD1 is the time from the point when the serpentine section 14 of the paper 10 that meets this condition is detected by the first sensor 30 to the point when the bonding tape 12 is detected by the second sensor 50. The first time interval TD1 is pre-stored in the memory 92.

[0067] If, in step S18, it is determined that the bonding tape 12 is detected during the first time period TD1, in step S20, the control unit 90 controls the paper 10 to be fed only for the first length Lt1, until the paper 10 is fed to the downstream end of the bonding tape 12 and moved to the first position PO1. Here, as Figure 1 As shown, the first length Lt1 is the length of the transport path RU from the second detection position PS2 of the second sensor 50 detecting the bonding tape 12 to the first position PO1. The first length Lt1 is determined in advance through experiments, etc., and is stored in advance in the memory 92 of the control unit 90.

[0068] In step S20, specifically, the control unit 90 controls the conveying of the product length based on the movable clamp 60 and the cutting based on the cutting blade 80 to be repeated na (na is a natural number) times, followed by conveying at a first adjustment distance and cutting based on the cutting blade 80, thereby conveying the paper 10 only at a first length Lt1. Here, the first adjustment distance is the distance obtained by subtracting the total conveying distance based on the conveying of the product length repeated na times from the first length Lt1. In step S20, before cutting the paper 10 at the first adjustment distance, the worker changes the insertion object of the paper 10 from the product 20 to the waste bin 22.

[0069] exist Figure 4In step S22, the control unit 90 controls the paper 10 to be fed only the second length Lt2 until it is moved to the second position PO2 at the downstream end of the bonding tape 12. Here, as Figure 1 As shown, the second length Lt2 is the length of the transport path RU from the first position PO1 to the second position PO2. The second length Lt2 is determined in advance through experiments, etc., and is stored in advance in the memory 92 of the control unit 90.

[0070] In step S22, specifically, the control unit 90 controls the paper 10 to be conveyed only to a second length Lt2 by repeatedly conveying the target length Lp based on the movable clamp 60 and cutting based on the cutting blade 80.

[0071] In step S23, the control unit 90 controls the paper 10 to be conveyed to the upstream end of the bonding tape 12 until it moves to the third position PO3. Specifically, the control unit 90 controls the paper 10 to be conveyed by repeatedly conveying based on the target length Lp of the movable clamp 60 and cutting based on the cutting blade 80.

[0072] Furthermore, in this embodiment, in order to convey the bonding tape 12 to a position that does not overlap with the first clamping position REm and the second clamping position REf, two steps are performed: conveying the first length Lt1 in step S20 and conveying the second length Lt2 in step S22. This is because, in the conveying device 1 of this embodiment, the combined distance of the first adjustment distance and the second adjustment distance exceeds the upper limit of the moving distance of the movable clamp 60. Therefore, when the combined distance of the first adjustment distance and the second adjustment distance does not exceed the upper limit of the moving distance of the movable clamp 60, the combined distance of the first adjustment distance and the second adjustment distance can be conveyed in one processing step.

[0073] exist Figure 4 In step S24, the control unit 90 controls the conveying of the product length based on the movable clamp 60 and the cutting based on the cutting blade 80 to be performed once. In addition, before cutting the paper 10 of the product length, the worker changes the insertion object of the paper 10 from the waste box 22 to the product 20.

[0074] In step S26, the control unit 90 controls the paper 10 to be fed to the downstream end of the serpentine section 14 until it moves to the third position PO3. Specifically, the control unit 90 controls the paper 10 to be fed by repeatedly feeding the target length Lp and cutting based on the cutting blade 80.

[0075] In step S26, specifically, the control unit 90 controls the calculation of the length of paper 10 to be transported from the downstream end of the serpentine section 14 to the third position PO3 by subtracting the length of paper 10 transported from step S12 to step S26. This determines the length of paper 10 to be transported until the downstream end of the serpentine section 14 reaches the third position PO3. Furthermore, the control unit 90 uses this length of paper 10 to set a target length Lp. For example, the target length Lp can be set by repeating the transport at the maximum travel distance of the movable clamp 60 multiple times, followed by a transport distance shorter than the maximum travel distance of the movable clamp 60.

[0076] Additionally, before cutting the paper 10 to the target length Lp, the worker changes the insertion object of the paper 10 from product 20 to waste bin 22. Similarly, regarding the following description of control A to the second routine control, paper 10 cut to product length is inserted into product 20, while paper 10 not of product length, or paper 10 containing joining tape 12 or serpentine sections 14, is inserted into waste bin 22. Therefore, for simplicity, the description of which of product 20 and waste bin 22 the paper 10 is inserted into is omitted in the following description.

[0077] In step S28, the control unit 90 controls the paper 10 to be fed to the upstream end of the serpentine section 14 until it moves to the third position PO3. Specifically, the control unit 90 controls the paper 10 to be fed multiple times by repeatedly feeding the target length Lp and cutting based on the cutting blade 80. The detailed processing of step S28 is the same as that of step S26, so it is omitted from the description. By performing step S28, the cutting of the serpentine section 14 is completed, and therefore the control unit 90 ends this processing flow.

[0078] If it is determined in step S18 that no bonding tape 12 is detected during the first time period TD1, in step S30, the control unit 90 determines whether the bonding tape 12 is detected during the second time period TD2, which is preset from the detection of the serpentine interval 14 in step S10.

[0079] (Control A)

[0080] In step S30, it is determined that the bonding tape 12 is detected during the second time period TD2, which corresponds to the above-mentioned control A (refer to...). Figure 2The second time TD2 is used to distinguish whether the bonding tape 12 is located on the downstream side or the upstream side of the serpentine section 14. The second time TD2 is the time from the point when the serpentine section 14 is detected by the first sensor 30 to the point when the downstream end of the serpentine section 14 reaches the point when the second sensor 50 detects the position of the bonding tape 12. The second time TD2 is predetermined through experiments, etc., and is stored in the memory 92 of the control unit 90.

[0081] If, in step S30, it is determined that the bonding tape 12 is detected during the second time period TD2, then in step S32, similarly to step S20, the control unit 90 controls the paper 10 to be fed only for the first length Lt1. In step S34, similarly to step S22, the control unit 90 controls the paper 10 to be fed only for the second length Lt2. In step S36, similarly to step S26, the paper 10 is fed until it reaches the third position PO3 at the upstream end of the serpentine section 14. As described above, when this control A is performed, the cutting at the downstream end of the serpentine section 14 is not performed, therefore the processing step of stopping the downstream end of the serpentine section 14 at the third position PO3 as in step S28 is not performed. By performing step S36, the cutting of the serpentine section 14 is completed, and therefore the control unit 90 ends this processing flow.

[0082] If, in step S30, it is determined that no bonding tape 12 is detected during the second time period TD2, then... Figure 5 In step S38, the control unit 90 determines whether the bonding tape 12 is detected during the period from the detection of the serpentine interval 14 in step S10 to the passing of the preset third time TD3.

[0083] (Control C)

[0084] In step S38, it is determined that the bonding tape 12 is detected during the third time period TD3, which corresponds to the above-mentioned control C (refer to...). Figure 3 The third time TD3 can be predetermined through experiments using paper 10 whose length Ld is determined to be the second reference length Ls2, located upstream of the serpentine section 14 by the bonding tape 12. The third time TD3 is the time from the point when the paper 10 meeting this condition is detected by the first sensor 30 in the serpentine section 14 to the point when the bonding tape 12 is detected by the second sensor 50. The third time TD3 is predetermined through experiments and stored in the memory 92 of the control unit 90.

[0085] If, in step S38, it is determined that the bonding tape 12 is detected during the third time period TD3, then in step S40, similarly to step S20, the control unit 90 controls the paper 10 to be fed only for the first length Lt1. In step S42, similarly to step S22, the control unit 90 controls the paper 10 to be fed only for the second length Lt2.

[0086] In step S44, similarly to step S23, the control unit 90 controls the paper 10 to be conveyed to the upstream end of the bonding tape 12 until it moves to the third position PO3. Since the serpentine section 14 is located downstream of the bonding tape 12, if step S44 is completed, the cutting of the serpentine section 14 and the bonding tape 12 is completed, and therefore the control unit 90 ends this processing flow.

[0087] If it is determined in step S38 that the bonding tape 12 is not detected during the period of the third time TD3, in step S48, the control unit 90 determines whether the bonding tape 12 is detected during the period of the preset fourth time TD4 from the detection of the serpentine interval 14 in step S10.

[0088] (Control B)

[0089] In step S48, it is determined that the bonding tape 12 is detected during the period of the 4th time TD4, which corresponds to the above-mentioned control B (refer to...). Figure 3 The fourth time TD4 can be predetermined through experiments using paper 10 that is upstream of the serpentine section 14 compared to the bonding tape 12 and whose determined length Ld is the second reference length Ls2. The fourth time TD4 is the time from the point when the serpentine section 14 of the paper 10 that meets the condition is detected by the first sensor 30 to the point when the bonding tape 12 is detected by the second sensor 50. The fourth time TD4 is stored in advance in the memory 92.

[0090] If, in step S48, it is determined that the bonding tape 12 is detected during the fourth time period TD4, in step S50, similarly to step S26, the control unit 90 controls the paper 10 to be fed to the downstream end of the serpentine section 14 until it moves to the third position PO3 before cutting. In step S52, similarly to step S28, the control unit 90 controls the paper 10 to be fed to the upstream end of the serpentine section 14 until it moves to the third position PO3 before cutting.

[0091] In step S54, the control unit 90 controls the paper 10 to be fed to the downstream end of the bonding tape 12 until it moves to the third position PO3. In step S56, similarly to step S22, the control unit 90 controls the paper 10 to be fed only for the second length Lt2. In step S58, similarly to step S36, the control unit 90 controls the paper 10 to be fed to the upstream end of the bonding tape 12 until it moves to the third position PO3. Since the serpentine section 14 is located downstream of the bonding tape 12, if step S58 is completed, the cutting of the serpentine section 14 and the bonding tape 12 is finished. Therefore, after performing step S58, the control unit 90 ends the processing flow.

[0092] If it is determined in step S48 that the bonding tape 12 has not been detected during the period of the fourth time TD4, in step S60, the control unit 90 determines whether the bonding tape 12 has been detected during the period of the pre-set fifth time TD5 from the time the serpentine interval 14 was detected in step S10.

[0093] (Second routine control)

[0094] In step S60, the determination that the bonding tape 12 is detected during the period of the 5th time TD5 corresponds to the second routine control. The 5th time TD5 can be predetermined by experiments using paper 10 that is upstream of the serpentine section 14 and has an interval Id equal to the first reference length Ls1. The 5th time TD5 is the time from the point when the serpentine section 14 of the paper 10 that meets the condition is detected by the first sensor 30 to the point when the bonding tape 12 is detected by the second sensor 50. The 5th time TD5 is pre-stored in the memory 92.

[0095] If, in step S60, it is determined that the bonding tape 12 is detected during the 5th time interval TD5, then in step S62, similarly to step S50, the control unit 90 controls the paper 10 to be conveyed to the downstream end of the serpentine section 14 until it reaches the 3rd position PO3. In step S64, similarly to step S52, the control unit 90 controls the paper 10 to be conveyed to the upstream end of the serpentine section 14 until it reaches the 3rd position PO3. In step S66, similarly to step S24, the control unit 90 controls the conveying based on the product length of the movable clamp 60 and the cutting based on the cutting blade 80 to be performed once.

[0096] In step S68, similarly to step S54, the control unit 90 controls the paper 10 to be fed to the downstream end of the bonding tape 12 until it moves to the third position PO3. In step S70, similarly to step S56, the control unit 90 controls the paper 10 to be fed only for the second length Lt2. In step S72, similarly to step S58, the control unit 90 controls the paper 10 to be fed to the upstream end of the bonding tape 12 until it moves to the third position PO3. If step S72 is completed, the cutting of the serpentine section 14 and the bonding tape 12 is completed, and therefore the control unit 90 ends this processing flow.

[0097] In step S60, the determination that no bonding tape 12 was detected during the 5th time interval TD5 means that no bonding tape 12 is present near the serpentine section 14. In this case, control is performed to cut off the serpentine section 14. Specifically, firstly, in step S76, similar to step S50, the control unit 90 controls the paper 10 to be fed to the downstream end of the serpentine section 14 until it moves to the 3rd position PO3. In step S78, similar to step S52, the control unit 90 controls the paper 10 to be fed to the upstream end of the serpentine section 14 until it moves to the 3rd position PO3. If step S78 is completed, the control unit 90 ends the processing flow.

[0098] Additionally, if the serpentine section 14 is not detected but the bonding tape 12 is detected, then proceed with... Figure 4 The processing steps shown from step S20 to step S23 involve cutting the adhesive tape 12 while avoiding clamping the adhesive tape 12 by the movable clamp 60 and the fixed clamp 70.

[0099] According to the embodiment described above, the conveying device 1 includes a movable clamp 60, a first sensor 30, a cutting blade 80, and a control unit 90. In step S12, the control unit 90 determines the serpentine section 14. Furthermore, the control unit 90 performs a first control (steps S26 and S28, steps S50 and S52) to cut the paper 10 by the cutting blade 80 at both the downstream end and the upstream end of the serpentine range containing the serpentine section 14. As a result, the serpentine section 14 can be cut off. Therefore, by not using the cut-off serpentine section 14 in the product 20, defects can be prevented.

[0100] Furthermore, the conveying device 1 includes a second sensor 50 and a fixing clamp 70. Upon detecting the bonding tape 12, the control unit 90 controls the conveyor to deliver the paper 10 to a position where the bonding tape 12 does not overlap with the first clamping position REm, and also to deliver the paper 10 to a position where the bonding tape 12 does not overlap with the second clamping position REf. This prevents the bonding tape 12 from being clamped by the movable clamp 60 and the fixing clamp 70. Therefore, it is possible to prevent a decrease in the quality of the paper 10.

[0101] Furthermore, when the bonding tape 12 is located downstream of the serpentine section 14 and the interval Id is at least the first reference length Ls1, the control unit 90 performs steps S26 and S28. In step S26, the control unit 90 controls the paper 10 to be fed to the downstream end of the serpentine section 14 until it reaches the third position PO3, and cuts it at the downstream end of the serpentine section 14 with the cutting blade 80. In step S28, the control unit 90 controls the paper 10 to be fed to the upstream end of the serpentine section 14 until it reaches the third position PO3, and cuts it at the upstream end of the serpentine section 14 with the cutting blade 80. This suppresses the length of waste paper 10, thus reducing manufacturing costs.

[0102] Furthermore, when the bonding tape 12 is located downstream of the serpentine section 14 and the interval Id is shorter than the first reference length Ls1, the control unit 90 performs control A. Control A includes a second control (S32) that moves the bonding tape 12 downstream to the first position PO1, a third control (S34) that moves the bonding tape 12 downstream to the second position PO2, and a fourth control (S36) that moves the serpentine section 14 upstream to the third position PO3 without cutting at the downstream end of the serpentine section 14. Thus, by setting the first reference length Ls1 to the product length, in cases where the paper 10 cannot be cut to the product length, the bonding tape 12 and the serpentine section 14 are continuously discarded, thereby omitting the cutting process at the downstream end of the serpentine section 14 and simplifying control.

[0103] Furthermore, when the bonding tape 12 is located upstream of the serpentine section 14 and its length Ld is determined to be shorter than the second reference length Ls2, the control unit 90 performs control C. Control C includes a fifth control (S40) that moves the bonding tape 12 downstream to the first position PO1 instead of moving it to the third position PO3 at the upstream end of the serpentine section 14; a sixth control (S42) that moves the bonding tape 12 downstream to the second position PO2; and a seventh control (S44) that moves the bonding tape 12 upstream to the third position PO3. Therefore, when the bonding tape 12 is held by the movable clamp 60 when the downstream end of the serpentine section 14 is to be cut, the bonding tape 12 being held by the movable clamp 60 is avoided more preferentially than cutting at the downstream end of the serpentine section 14, thereby preventing a decrease in the quality of the paper 10.

[0104] B. Other implementation methods:

[0105] (B1) In the above embodiment, in the first process, the cutting is performed at both the upstream and downstream ends of the serpentine section 14. Alternatively, the cutting can be performed at both the upstream and downstream ends of the serpentine range encompassing the serpentine section 14. That is, the cutting can be performed at a location far from the upstream end of the serpentine section 14, or at a location far from the downstream end of the serpentine section 14. Regardless of the cutting location, defects can be prevented by removing the serpentine section 14.

[0106] (B2) In the above embodiment, the conveying device 1 includes a fixing clamp 70. Alternatively, the conveying device 1 may not include the second sensor 50 or the fixing clamp 70. Furthermore, in the above embodiment, for example, in the first conventional control, in steps S20 to S23 and steps S26 and S28, the cut paper 10 is discarded into the waste bin 22. However, regarding paper 10 cut to the same length as the product, the product 20 can be appropriately provided instead of the waste bin 22 and inserted into the product 20.

[0107] (B3) In the above embodiment, the conveying device 1 includes a creasing roller 40. In other embodiments, the conveying device 1 may not include the creasing roller 40. Even without the creasing roller 40, if the paper 10 is cut by the cutting blade 80 in the serpentine section 14, there is a possibility that the paper 10 may be cut at an angle relative to its width direction, resulting in a defect. In this case, the defect can be prevented by applying the present invention. Furthermore, while the above embodiment includes the creasing roller 40, the conveying device 1 can also be adapted to the present invention with a structure that does not include the creasing roller 40 but includes, for example, a processing section for forming slits on long components or for performing processing such as bending long components.

[0108] (B4) In the above embodiment, paper 10 is exemplified as a long component. The material of the long component is not limited to paper; for example, it may be metal, synthetic resin, wood, etc. Furthermore, the order of the first sensor 30, the indentation roller 40, and the second sensor 50 is not limited to the above order.

[0109] (B5) In the above embodiment, the control unit 90 uses the length of the serpentine interval 14 to determine whether it is an outlier in step S14. In other embodiments, the control unit 90 may also use the time from the moment serpentine is detected to the moment serpentine is no longer detected to determine whether it is an outlier, instead of using the length of the serpentine interval 14.

[0110] (B6) In the above embodiment, in step S12, the length of the serpentine interval 14 is calculated. In step S14, if the length of the serpentine interval 14 is above an abnormal value, an error is notified in step S16. Alternatively, the process can be configured as follows: if the time for which the position offset is detected by the first sensor 30 exceeds an abnormal value equivalent to the length, an error is notified. That is, the process flow can be configured as follows: if the serpentine movement is not eliminated, step S16 is performed.

[0111] This invention is not limited to the embodiments described above, and can be implemented in various structures without departing from its spirit. For example, in order to solve some or all of the above-described problems, or to achieve some or all of the above-described effects, the technical features of the embodiments corresponding to the technical features in the various methods described in the summary section of the invention can be appropriately replaced or combined. Furthermore, if the technical features are not described as essential in this specification, they can be appropriately deleted.
