The roller 15 is at least one, and the shaft 29 of the turntable 31 is inserted into the through hole 41 and is rotated by the rotation support part 13.

In this tape delivery apparatus 100, the roller 15 is installed so that a plurality of layers may be stacked by inserting the shaft 29 through the through hole 41. In this embodiment, the roller 15 is installed in two layers. In addition, the number of installation layers of the drum 15 is not limited to this.

The roller 15 stacked with a plurality of layers is the delivery terminal 53 of the zipper tape 35 wound on the adjacent roller 15 and is connected by the connecting portion 57 to the roller 15 wound on the other adjacent roller 15 The sending out start end 55 of the zipper tape 35. For the connecting portion 57, a colored tape that is different in color from the fastener tape 35, for example, is used.

The traction part 17 is provided on the base part 11, and conveys the zipper tape 35 in the sending direction. The pulling part 17 is provided with a pair of pinching rollers 59 which pinch the fastener tape 35 from the thickness direction. The pinching roller 59 may be driven by both sides, or either one may be a driving roller and the other may be a driven roller. The pinching roller 59 is driven simultaneously with the rotating table 31. The pulling portion 17 is rotated while clamping the fastener tape 35 by the pair of pinching rollers 59, thereby pulling and conveying (pulling) the fastener tape 35 in the sending direction.

The traction part 17 is provided with a guide ring 61 on the upstream side (that is, the drum side) in the feeding direction with respect to the pinch roller 59. The guide ring 61 is attached to the inside and inserted through the zipper tape 35 to guide the zipper tape 35 being sent out, and determine the introduction position of the zipper tape 35 with respect to the pinching roller 59.

The pulling portion 17 is attached to the upstream side of the guide ring 61 in the sending direction, and a connecting portion detection sensor 63 for detecting the connecting portion 57 is installed. The connection part detection sensor 63 is constituted by, for example, a color detection sensor, and detects the passage of the connection part 57 by detecting the color of the connection part 57. Thereby, it is detected that the feeding of the drum 15 is finished.

The tape delivery device 100 is attached to the base 11, and is provided with an elevating mechanism 65 corresponding to the roller 15 through which the zipper tape 35 is delivered out of the stacked rollers 15 to raise and lower the traction unit 17. The lifting mechanism 65 is controlled by the device control unit to lift. The device control unit, upon receiving the detection signal of the connection portion 57 from the connection portion detection sensor 63, outputs a lifting signal to the lifting mechanism 65. When the lifting mechanism 65 is input with a lifting signal, the lifting driving part 67 is driven to move the traction part 17 to the position (height) of the next drum 15.

The pulling portion 17 is provided with a temporary storage box 69 on the downstream side in the delivery direction of the pinch roller 59. In the temporary storage box 69, the fastener tape 35 conveyed from the pinching roller 59 is temporarily accommodated by a fixed amount. In this temporary storage box 69, the presence or absence of the fastener tape 35 can be detected by the tape detection sensor 71.

The tape delivery device 100 stops the pinching roller 59 when the temporary storage box 69 detects the fastener tape 35. The tape delivery device 100 is connected to a bag making machine (not shown) connected to the downstream side of the temporary storage box 69 using the fastener tape 35. The zipper tape 35 temporarily accommodated in the temporary accommodation box 69 is pulled out and conveyed to the bag making machine by the conveyance roller 73. The tape delivery device 100 is designed to eliminate slack when the zipper tape 35 of the temporary storage box 69 is pulled out. When the tape detection sensor 71 fails to detect the zipper tape 35 of the temporary storage box 69, the tape delivery device 100 drives the pinching roller 59 and the rotating table 31 so that a certain amount of the zipper tape 35 is stored again The operation control is performed by temporarily storing the box 69. That is, the pulling part 17 and the rotating table 31 operate intermittently.

In addition, although one of the pinch rollers 59 shown in FIG. 1 is shown in a direction in which the center of rotation is the horizontal direction for convenience of description, the direction of the pinch roller 59 is not limited to this. In this case, the zipper tape 35 is fastened between the roller 15 and the pinching roller 59 and twisted by 90°. As shown in Fig. 3, the pinching roller 59 may be arranged in a direction in which the center of rotation becomes a vertical direction. In this case, the zipper tape 35 is tied between the roller 15 and the pinching roller 59 to maintain the longitudinal conveyance.

Fig. 2 is a perspective view of a special part of the vicinity of the drum shown in Fig. 1.　　The arm part 19 is provided on the base part 11. On the base 11, a swing support shaft 75 that is in the same direction as the shaft 29 of the turntable 31 is vertically provided. The arm portion 19 is supported so that the swing base end can swing freely with the swing support shaft 75 as the center. The arm portion 19 is formed to be bent into a substantially L-shape or a substantially U-shape in a plan view. The arm portion 19 is provided in a pair for one roller 15 in this embodiment. The pair of arm portions 19 is to abut the swinging front end 77 against the winding outer peripheral surface of the winding body 51 of the fastener tape 35. The arm portion 19 abuts the swing tip 77 against the winding outer peripheral surface of the wound body 51, thereby pressing the wound body 51 toward the inside of the winding radius.

The swing tip 77 of the arm portion 19 is centered on the roller center in the same direction as the shaft 29, and the roller 79 is rotatably supported. That is, the pair of arm portions 19 rotatably supports both ends of the roller 79. The roller 79 is formed so that the length in the axial direction substantially coincides with the interval between the pair of flange portions 39. Therefore, the roller 79 is configured to be able to press the winding outer peripheral surface of the wound body 51 across the direction along the axis.

Fig. 3 is a plan view illustrating the direction of movement of each part of the tape delivery device 100 shown in Fig. 1.　　 In the tape delivery device 100, the arm portion 19 is set in a circumferential direction centered on the rotation center of the drum 15, and a plurality of arms 19 are provided at equal intervals. In this embodiment, three arm portions 19 are arranged in the circumferential direction. That is, the wound body 51 is configured to press and wind the outer peripheral surface by the roller 79 at every 120° angle.

The arm portion 19 is pushed by a pushing means that moves the swing front end 77 toward the inner side of the winding radius of the winding body 51. As the pushing means, for example, a tension spring 81 is used. The extension spring 81 is connected to the arm 19 at one end, and fixed to the spring support column 83 fixed to the base 11 at the other end. The tension spring 81 is spanned between the arm portion 19 and the spring support column 83, thereby pressing the roller 79 against the winding outer peripheral surface of the winding body 51. The pressing force of the roller 79 caused by the tension spring 81 is set to be greater than the pulling force of the zipper tape 35 caused by the pressing roller 59. That is, the roller 79 does not float from the outer peripheral surface of the winding body 51 due to the pulling force of the pinching roller 59. In addition, the pushing means may be composed of a pneumatic cylinder. By using a pneumatic cylinder, the pressing force of the roller 79 on the outer peripheral surface of the winding body 51 can be adjusted. For example, the roller 79 can be pressed with the optimal pressure according to the type or material of the tape being wound. .

In the tape delivery device 100, a winding diameter detection sensor 85 that detects the winding diameter of the wound body 51 is provided across the swing support shaft 75 and the arm portion 19. The rotation support portion 13 controls the rotation drive speed according to the detection value of the winding diameter detection sensor 85. That is, the device control unit confirms the winding diameter of the winding body 51 with the winding diameter detection sensor 85 and controls to change the speed of the turntable 31. The winding diameter detection sensor 85 uses, for example, a proximity sensor, and detects the diameter (winding diameter) of the winding body 51 based on the swing angle of the arm portion 19.

Next, the operation of the tape delivery device 100 having the aforementioned configuration will be described.　　 Figure 4 is an explanatory diagram of the operation when the drum is installed.　　 On the drum 15, the fastener tape 35 is wound so that a flat surface is parallel to the outer periphery of the bobbin part 37. As shown in FIG. The drum 15 is installed so that the shaft 29 of the turntable 31 passes through the through hole 41. At this time, the arm portion 19 is swung to a position where it does not interfere with the drum 15 to retreat. The roller 15 is attached to the rotating table 31 with the required number of layers.

Figure 5 is an explanatory diagram of the operation when the arm is installed.　　 After the installation of the drum 15 on the turntable 31 is completed, the arm 19 presses the winding outer peripheral surface of the wound body 51.

Fig. 6 is an operation explanatory diagram of the step of inserting the guide ring of the tape or the like.　　 Rotate the roller 15 in the sending direction by hand or the like, so that the starting end of the fastener tape 35 passes through the guide ring 61. In this embodiment, the upper roller 15 becomes the initial roller 15. Next, the delivery start end 55 of the wound body 51 wound on the upper drum 15 is passed through the guide ring 61. The zipper tape 35 that has passed the guide ring 61 is clamped by the pinching roller 59. After slackening the start end of the fastener tape 35 in the temporary storage box 69, it hangs on the conveyance roller 73, and introduces into the supply mechanism of a bag making machine.

In this state, the adjacent drum 15 is the delivery terminal 53 of the wound body 51 of one drum 15, and is connected to the delivery start end 55 of the wound body 51 of the other drum 15 by the connection part 57. That is, the delivery terminal 53 of the upper roller 15 is connected to the delivery start end 55 of the lower roller 15 by the connection part 57. Thereby, the tape delivery apparatus 100 completes the preparation before operation.

The tape delivery device 100 is on standby in a stopped state while the tape detection sensor 71 detects the fastener tape 35 accommodated in the temporary storage box 69. As the bag making machine performs bag making, when the zipper tape 35 is pulled out from the temporary storage box 69, the tape detection sensor 71 detects that there is no zipper tape 35 in the temporary storage box 69. The device control part, when receiving the empty signal of the zipper tape 35, drives the rotating table 31 and the pinching roller 59. When the zipper tape 35 that has fallen from the pinch roller 59 is stored in the temporary storage box 69 for a certain amount, the device control unit sends it out to stop the pinch roller 59 and the rotating table 31, and becomes standby until the next tape replenishment. State control signal.

FIG. 7 is an explanatory diagram of the operation when the winding body 51 reaches the minimum winding diameter. The rotating table 31 and the pinching roller 59 repeat the aforementioned intermittent operation. When the winding body 51 of the drum 15 reaches the minimum winding diameter, the fastener tape 35 is removed from the bobbin portion 37.

Figure 8 is an explanatory diagram of the operation when the rollers are switched.　　 The zipper tape 35 pulled out by the pinching roller 59 is continuously pulled out by the connecting portion 57 connected to the delivery terminal 53 of the initial roller 15 to the delivery start end 55 of the roller 15 of the next layer. Thereby, the zipper tape 35 is finished to transfer from the initial roller 15 to the roller 15 of the next layer.

Fig. 9 is an explanatory diagram of the operation when the new roller starts to be sent out after the roller is switched.　　 zipper tape 35, along with the transfer of the drum 15, the connection part 57 is a sensor 63 for detecting the connection part. The device control unit drives the elevating mechanism 65 so that the elevating mechanism 65 arranges the traction section 17 to a position corresponding to the drum 15 of the next stage when the connecting portion detection sensor 63 detects the connecting portion 57. In this embodiment, since the initial drum 15 is the upper stage, the lifting mechanism 65 lowers the traction unit 17 to the position of the lower drum 15. Thereby, the transfer operation of the drum 15 is all finished.

Next, the function of the aforementioned configuration will be explained. "In the tape feeding device 100 of this embodiment, the roller 15 wound with the fastener tape 35 is supported by the rotation support part 13 with the shaft 29 passing through the through hole 41. As shown in FIG. The fastener tape 35 is wound around the drum 15 so that the tape width direction may become a direction along the vertical direction, that is, the vertical direction.

If the zipper tape 35 is tightly wound, it may cause permanent deformation to the product. On the other hand, if the winding of the fastener tape 35 is slack, especially for those who are prone to slippage like the fastener tape 35, there is a risk of sliding in the width direction due to gravity, and the winding is likely to be loose.

In the tape feeding device 100, the wound body 51 in such a slack wound state that does not cause permanent deformation is fed while being pressed by the arm portion 19 to wind the outer peripheral surface. That is, the fastener tape 35 can suppress the sliding of the width direction due to gravity by the arm part 19. Therefore, in the tape delivery device 100, the fastener tape 35 can maintain a good shape without permanent deformation, and can be delivered smoothly without being entangled, twisted, or bent.

In addition, in the tape delivery device 100, when the drum 15 rotates, on the outer peripheral surface of the winding body 51 wound on the drum 15, the roller 79 is supported by the center of the roller in the same direction as the shaft 29 Attach and rotate. Therefore, the fastener tape 35 and the roller 79 on the outer peripheral surface of the winding body 51 do not slide relative to each other. The winding body 51 can be pressed so that the fastener tape 35 is not rubbed by the swinging front end 77 of the arm 19 even during rotation. Therefore, the arm portion 19 can suppress the looseness of the winding so that the fastener tape 35 is not damaged.

In addition, in the tape delivery device 100, the arm portion 19 is swingably supported by the swing support shaft 75, and the swing tip 77 is directed toward the inner side of the winding radius of the winding body 51 by means of a push spring. Push the bomb in the direction of movement. That is, the arm portion 19 presses the winding outer peripheral surface of the wound body 51 by the pressing force, thereby suppressing winding looseness. As the pushing means, when a tension spring is used, the pressing force for the winding body 51 with a large outer diameter is greater than the pressing force for the winding body 51 with a small outer diameter. Thereby, it is possible to strongly press the winding body 51 with a large outer diameter, which is more likely to cause winding looseness than a smaller outer diameter. In addition, when a pneumatic cylinder is used as the pushing means, even if the winding diameter is changed, the pressing force on the wound body 51 can be controlled to a pressing force suitable for the diameter and pressing. Therefore, it is possible to apply an appropriate pressing force to the arm portion 19 that does not cause winding looseness.

In addition, in this tape delivery device 100, the pressing portion caused by the swinging front end 77 of the arm portion 19 may be plural at equal intervals in the direction along the winding outer peripheral surface of the wound body 51. Therefore, the winding body 51 of the drum 15 can suppress the winding looseness uniformly compared with the structure which presses and winds the outer peripheral surface by the several swing front-end|tip 77 at unequal intervals. Therefore, the interval in the circumferential direction of the wound body 51 pressed by the arm portion 19 can be made uniform and small, and winding looseness can be made less likely to occur.

In addition, in the tape delivery device 100, the fastener tape 35 can be continuously delivered in the order of the stacked rollers 15. Therefore, compared with the structure which installs the roller 15 individually and sends out the fastener tape 35, the tape delivery apparatus 100 can eliminate the stop time required for roller replacement, and can improve the operation efficiency. Therefore, the continuous operation time at the time of bag making using the drum 15 wound with the fastener tape 35 can be lengthened.

In addition, in the tape delivery device 100, the delivery terminal 53 of the zipper tape 35 wound on the adjacent roller 15 is connected to the adjacent roller 15 through the connecting portion 57. 15 is the starting end 55 of the zipper tape 35 to be sent out. Therefore, at the same time that the feeding of one fastener tape 35 is completed, it is possible to shift to the feeding of the fastener tape 35 of the next drum 15. Therefore, the fastener tape 35 can be continuously sent out by jumping over the roller 15 that has finished sending out to the roller 15 that has started sending out. That is, the drum 15 can be operated continuously for two rolls, and if it is the aforementioned roll length, it can be operated continuously for an amount of 4000m×2=8000m.

In addition, in the tape delivery device 100, the aforementioned connecting portion 57 is detected to drive the lifting mechanism 65 to move the pulling portion 17 to a position corresponding to the roller 15 to be delivered next. Thereby, even when the roller 15 is stacked in plural layers, the distance or the inclination of the roller 15 and the pulling part 17 can be kept constant, and the fastener tape 35 can be sent out smoothly. Therefore, it is possible to suppress the inclination between the roller 15 for sending out the fastener tape 35 and the traction part 17, making the fastener tape 35 less likely to be entangled, twisted, and bent.

In addition, in the tape delivery device 100, when the rotation support portion 13 is driven, the winding diameter detection sensor 85 can detect the position of the winding outer peripheral surface of the current winding body 51, that is, the winding body 51 diameter. The position of the winding outer peripheral surface of the wound body 51 can be detected by, for example, the swing angle of the arm portion 19 where the swing tip 77 is in contact with the winding outer peripheral surface. The tape delivery device 100 controls the number of rotations of the rotation support portion 13 so that the delivery amount of the fastener tape 35 is constant based on the detection value of the outer diameter of the winding body 51. That is, the rotation support portion 13 rotates at a low speed when the winding body 51 has a large outer diameter, and rotates at a high speed when the winding body 51 has a small outer diameter. Therefore, the rotation drive speed of the rotation support part 13 can be controlled according to the outer diameter of the winding body 51, and the fastener tape 35 can be conveyed to the pulling part 17 by a constant sending amount.

Therefore, according to the tape delivery device 100 of the present embodiment, it is possible to suppress entanglement, twisting, and bending caused by loose winding of the fastener tape 35 wound on the drum 15.

The present invention is not limited to the foregoing embodiments, and the various components of the embodiments may be combined with each other, or those who have ordinary knowledge in the technical field of the invention who make changes and applications based on the description of the specification and the known technology are also included in the claims of the present invention.

In addition, the number of installation layers of the roller may be one, or three or more. In addition, the tape delivery device may be provided with a plurality of rotating tables at the base. At this time, the adhesive tapes of all the rollers can be connected in series by the connecting portion, thereby enabling continuous operation.

In addition, in the foregoing embodiment, although an example of unwinding from the upper layer of the two-layer drum 15 and sending out and continuing to the lower layer of the drum 15 is described, the lower drum 15 is first unwinded and sent out and continued to the upper layer. The order of the drum 15 may also be used. At this time, it is preferable that the delivery terminal 53 of the fastener tape 35 wound on the lower drum 15 is located at the upper end position of the bobbin part 37. In the lower drum 15, the remaining zipper tape 35 of the bobbin part 37 that is about to reach the delivery terminal 53 will be unwound from below the bobbin part 37 to the upper side in the vertical direction, so that the zipper tape 35 is not affected by itself. The weight shifts toward the loosening direction and is not easily entangled, so it can be sent out smoothly and transferred to the upper drum 15 through the connection part 57.

In this state, as shown in FIG. 14, the clip body 125 is arranged with the tip end inclined.

In addition, the clamp body 125 clamps the vicinity of the connecting portion 57 of the fastener tape 35 by spring force. The clamping force is small, and the zipper tape 35 can be kept in a state of tension to the extent that the zipper tape 35 does not loosen, and it can be easily removed from the clamp body 125 in the clamped state when the zipper tape 35 is pulled. The temporarily fixed state.

In the tape delivery device 200 configured in this way, first, the zipper tape 35 is wound on the drum 15 so that the flat surface is parallel to the outer circumference of the bobbin portion 37, and the drum 15 is relative to the shaft 91 of the turntable 31. The lower end side of the through hole 41 is inserted and installed. At this time, the pair of driving claws 93 of the turntable 31 are fitted into the recessed portion 40 formed in the flange portion 39 a of the drum 15. When a plurality of rollers 15 are connected, for example, two, the holding portion 121 is attached to the flange portion on the upper side of the roller 15 installed on the turntable 31 first. Next, the connecting block 42 is fitted to the recessed portion 40 of the flange 39a of the lower roller 15 and the roller 15 is further overlapped on the roller 15, and the recessed portion 40 of the upper roller is fitted to the connecting block 42 to make the roller Become a connected state. In addition, the vicinity of the connecting portion 57 between the delivery end of the fastener tape 35 of the upper roller 15 and the delivery start end 55 of the fastener tape 35 of the lower roller 15 is clamped by the clamp body 125 of the holding portion 121 (refer to Figure 14).

Immediately after the installation of the drum 15 on the turntable 31 is completed, the winding looseness preventing part 115 is operated at the lower and upper layers, respectively, and the winding body 51 is supported from the outer peripheral surface by the curved plate 117.

The roller 15 is rotated manually or the like in the delivery direction, and the starting end of the fastener tape 35 passes through the vertical guide roller 103 and the horizontal guide roller 101. In this second embodiment, the upper roller 15 becomes the initial roller 15. Next, the delivery start end 55 of the wound body 51 wound on the upper drum 15 is passed. The zipper tape 35 that has passed through the guide rollers 103 and 101 passes through the support roller 97 and the slack prevention roller 99 of the slack prevention mechanism 95 and is clamped by the pinching roller 59. The slack prevention roller 99 is equipped with a weight, and at the position of this slack prevention roller 99, the fastener tape 35 will be in the reflexed state of a descending direction and an ascending direction. The start end of the fastener tape 35 that has passed the pinching roller 59 is then hooked on the support roller 109 and the tension adjustment roller 111 of the conveying amount control unit 107, and is introduced to the supply mechanism of the bag making machine. In this conveyance amount control part 107, the fastener tape 35 also positions the tension adjustment roller 111 below, and it becomes a reflexed state.

Thereby, the tape delivery apparatus 200 completes the preparation before operation.

The tape feeding device 200 makes the pinching roller 59 stand by in a stopped state while the zipper tape 35 is detected by the zipper recognition sensor 133 by the tension adjusting roller 111 of the conveying amount control unit 107. As the bag making machine makes bags, when the zipper tape 35 is pulled out from the conveying amount control part 107 and the tension adjustment roller 111 rises, the zipper recognition sensor 133 cannot detect the zipper tape 35, and the device control part receives the signal, Thus, the pinching roller 59 is driven.

The device control unit sends out the fastener tape 35 from the slack prevention mechanism unit 95 by driving the pinching roller 59. The sending start sensor 135 provided in the slack prevention mechanism 95 detects that the position of the slack prevention roller 99 is the rising position or the lower position, and if the rising position of the slack prevention roller 99 is detected, the rotation support portion 13 is driven to perform the rotation of the drum 15 The rotation starts to send out the fastener tape 35.　　 By the detection of the zipper identification sensor 133 and the sending start sensor 135, the traction part 17 and the rotation support part 13 are driven, and the zipper tape 35 is sent out to the bag making machine.

The rotating table 31 and the pinching roller 59 repeat the aforementioned intermittent operation. When the winding body 51 of the drum 15 reaches the minimum winding diameter, the zipper tape 35 is removed from the bobbin portion 37.

The zipper tape 35 pulled out by the pinching roller 59 is continuously pulled out by the connecting portion 57 connected to the delivery terminal 53 of the initial roller 15 to the delivery start end 55 of the roller 15 of the next layer. At this time, the zipper tape 35 clamped by the clamp body 125 of the holding part 121 can be easily removed by the force of the pulling part 17, the slack prevention mechanism part 95, and the rotation support part 13, or any one of them. Then, the zipper tape 35 finishes the transfer from the initial roller 15 to the roller 15 of the next layer.

As for the zipper tape 35, the connecting part 57 passes through the connecting part detection sensor 63 along with the transfer of the roller 15. The control unit of the device, when the connection detection sensor 63 detects the connection 57, causes the lifting mechanism 65 to arrange the slack prevention mechanism 95, the traction unit 17, and the conveyance control unit 107 to the roller 15 corresponding to the next level. In the manner of position, the lifting mechanism 65 is driven. In the second embodiment, since the initial drum 15 is the upper stage, the elevating mechanism 65 lowers the parts 17, 95, and 107 to the position of the drum 15 on the lower stage. Thereby, the transfer operation of the drum 15 is all finished.

Next, the function of the aforementioned configuration will be explained. In the tape delivery device 200 of the second embodiment, similar to the tape delivery device 100 of the first embodiment described above, the roller 15 wound with the zipper tape 35 is inserted into the through hole 41 or the shaft 29 The upper and lower rollers 15 are connected by the connecting block 42 and supported by the rotation support part 13. The fastener tape 35 is wound around the drum 15 so that the tape width direction may become a direction along the vertical direction, that is, the vertical direction.

If the zipper tape 35 is tightly wound, it may cause permanent deformation to the product. On the other hand, if the winding of the fastener tape 35 is slack, especially for those who are prone to slippage like the fastener tape 35, there is a risk of sliding in the width direction due to gravity, and the winding is likely to be loose.

In the tape feeding device 200, the wound body 51 in such a slack wound state that does not cause permanent deformation is fed while tension is applied by the slack prevention mechanism 95. That is, the slack preventing roller 99 of the slack preventing mechanism 95 will drop due to gravity, whereby the zipper tape 35 will be pulled from the roller 15 to the pinching roller 59 of the traction unit 17 without slack, and at the same time, it is supported by controlling the rotation. The delivery speed of the portion 13 suppresses slack. Therefore, in the tape delivery device 200, the fastener tape 35 can maintain a good shape without permanent deformation, and can be delivered smoothly in a state with appropriate tension without entanglement, twisting, or bending.

In addition, in this tape delivery device 200, the fastener tape 35 can be delivered continuously in the order of the stacked rollers 15. Therefore, the tape delivery device 200 can eliminate the stop time required for roller replacement and improve the operation compared to the configuration in which the roller 15 is individually installed and the zipper tape 35 is sent out, that is, compared to the configuration in which the roller 15 is operated one by one. effectiveness. Therefore, the continuous operation time at the time of bag making using the drum 15 wound with the fastener tape 35 can be lengthened.

In addition, in the tape delivery device 200, the delivery terminal 53 of the zipper tape 35 wound on the adjacent roller 15 is connected to the adjacent roller 15 through the connecting portion 57. 15 is the starting end 55 of the zipper tape 35 to be sent out. Therefore, at the same time that the feeding of one fastener tape 35 is completed, it is possible to shift to the feeding of the fastener tape 35 of the next drum 15. Therefore, the fastener tape 35 can be continuously sent out by jumping over the roller 15 that has finished sending out to the roller 15 that has started sending out. That is, the drum 15 can be operated continuously for two rolls, and if it is the aforementioned roll length, it can be operated continuously for an amount of 4000m×2=8000m.

In addition, in the tape delivery device 200, the connecting portion 57 between the fastener tapes 35 wound around the adjacent rollers 15 is the clip body 125 held by the holding portion 121, and the fastener tape 35 between the rollers 15 It is not easy to loosen when it is sent out, and it is not easy to cause loose winding. In addition, since the fastener tape 35 is clamped while being temporarily held by the clip body 125, when the part of the connecting part 57 is sent out, it can be easily removed by the force of the pulling part 17 or the slack preventing mechanism part 95, etc. Thereby, the fastener tape 35 is sent out smoothly.

In addition, in the tape delivery device 200, the aforementioned connecting portion 57 is detected, thereby driving the lifting mechanism 65, and the pulling portion 17 and the like are moved to a position corresponding to the roller 15 to be delivered next. Thereby, even when the roller 15 is stacked in plural layers, the distance or the inclination of the roller 15 and the traction part 17, etc. can be kept constant, and the fastener tape 35 can be sent out smoothly. Therefore, it is possible to suppress the inclination between the roller 15 for sending out the fastener tape 35 and the traction part 17, making the fastener tape 35 less likely to be entangled, twisted, and bent.

In addition, in the tape delivery device 200, a slack prevention mechanism 95 is arranged between the rotation support part 13 on the side where the fastener tape 35 is sent out and the traction part 17 on the side where the fastener tape 35 is drawn, so that the fastener tape 35. With the slack prevention roller 99 as the tension adjustment roller, even if there is a speed difference between the rotation support portion 13 and the traction portion 17, tension will be applied. If the conveying side becomes faster, the slack prevention roller 99 will drop downward. When the side becomes slower, the slack prevention roller 99 rises upward, and the position of the slack prevention roller 99 is detected by the sensor 135. If it falls, the speed of the rotation support 13 as the conveying side is reduced, and if it rises, the speed is increased. Ascent, in addition, the pulling speed of the pulling portion 17 is also controlled, thereby enabling stable feeding control.

Therefore, according to the tape delivery device 200 of the second embodiment, it is possible to suppress entanglement, twisting, and bending caused by loose winding of the fastener tape 35 wound on the drum 15, and to suppress slack between the pulling parts 17 .
