Therefore, the flange portion 39 is formed to be larger than the outer diameter (winding outer diameter) of the winding body 51.

The drum 15 is at least one, and the shaft 29 of the rotary table 31 is inserted into the through hole 41 and is rotated by the rotary support portion 13.

In this tape feeding device 100, the roller 15 is installed in such a manner that a plurality of layers are stacked by inserting the shaft 29 through the through hole 41. In this embodiment, the drum 15 is provided with two layers. In addition, the number of installation layers of the drum 15 is not limited to this.

The rollers 15 stacked in multiple layers are the delivery terminals 53 of the zipper tape 35 wound around the adjacent roller 15, and are connected to the rollers 15 wound around the other roller 15 by connecting portions 57. The delivery start end 55 of the fastener tape 35. For the connecting portion 57, for example, a colored adhesive tape colored in a different color from the fastener tape 35 is used.

The pulling portion 17 is provided on the base portion 11 and sandwiches the zipper tape 35 to be conveyed in the sending direction. The pulling portion 17 includes a pair of pinch rollers 59 that pinch the fastener tape 35 in the thickness direction. The pinch roller 59 may be driven by both sides in rotation, or either one may be a driving roller and the other may be a driven roller. The pinch roller 59 is driven simultaneously with the rotary table 31. The pulling portion 17 is rotated by the pair of pinch rollers 59 while sandwiching the fastener tape 35, thereby pulling and conveying (tracting) the fastener tape 35 in the sending direction.

The traction unit 17 has a guide ring 61 on the upstream side (that is, the drum side) in the sending-out direction with respect to the pinch roller 59. The guide ring 61 is inserted into the inside of the fastener tape 35, guides the fastener tape 35 being sent out, and determines the introduction position of the fastener tape 35 to the pinch roller 59.

The traction unit 17 is attached to the upstream side of the guide ring 61 in the sending direction, and is provided with a connection part detection sensor 63 for detecting the connection part 57. The connection part detection sensor 63 is composed of, for example, a sensor that detects a color, and detects the passage of the connection part 57 by detecting the color of the connection part 57. With this, the delivery of the drum 15 is detected to be completed.

The tape delivery device 100 is attached to the base 11 and is provided with an elevating mechanism 65 corresponding to the aforementioned roller 15 from which the zipper tape 35 is sent out among the stacked plural layers of rollers 15 to raise and lower the traction portion 17. The lifting mechanism 65 is controlled by the device control unit to move up and down. When the device control unit receives the detection signal of the connection unit 57 from the connection unit detection sensor 63, it outputs a lift signal to the lift mechanism 65. When a lifting signal is input to the lifting mechanism 65, the lifting driving section 67 is driven to move the pulling section 17 to the position (height) of the next drum 15.

The traction unit 17 is provided with a temporary storage box 69 on the downstream side in the feeding direction of the pinch roller 59. In the temporary storage box 69, the fastener tape 35 conveyed from the pinch roller 59 is temporarily stored in 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 feeding device 100 stops the pinch roller 59 when the temporary storage box 69 detects the fastener tape 35. The tape delivery device 100 uses a fastener tape 35 in a bag making machine (not shown) connected to the downstream side of the temporary storage box 69. The zipper tape 35 temporarily stored in the temporary storage box 69 is pulled out and transported to the bag making machine by the transport roller 73. In the tape feeder 100, when the zipper tape 35 of the temporary storage box 69 is pulled out, the slack is eliminated. The tape feeding device 100 is such that when the tape detection sensor 71 cannot detect the zipper tape 35 of the temporary storage box 69, the pinch roller 59 and the rotary table 31 are driven to allow a certain amount of zipper tape 35 to be stored again Operation control is performed by temporarily storing the box 69. That is, the traction unit 17 and the turntable 31 operate intermittently.

In addition, although the pinch roller 59 is shown in one of FIG. 1 for convenience of explanation, the direction in which the rotation center is horizontal is shown, but the direction of the pinch roller 59 is not limited to this. In this case, the fastener tape 35 is twisted 90 ° between the drum 15 and the pinch roller 59. As shown in FIG. 3, the pinch roller 59 may be arranged in a direction in which the center of rotation becomes the vertical direction. In this case, the fastener tape 35 is conveyed between the drum 15 and the pinch roller 59 while maintaining the longitudinal direction.

FIG. 2 is a perspective view of a special part of the vicinity of the drum shown in FIG. 1. The arm portion 19 is provided on the base portion 11. A swing support 75 in the same direction as the axis 29 of the turntable 31 is erected on the base 11. The arm portion 19 is supported by the swing support shaft 75 as a center so that the swing base end can swing freely. The arm portion 19 is formed so as to flex in a substantially L-shape or a substantially letter-shape when viewed from above. In the present embodiment, the arm portion 19 is provided with a pair of one roller 15. The pair of arm portions 19 abuts 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 presses the swinging tip 77 against the winding outer peripheral surface of the winding body 51, thereby pressing the winding body 51 toward the inside of the winding radius.

The swinging front end 77 of the arm portion 19 is rotatably supported by a roller 79 centered on the center of the roller in the same direction as the shaft 29. 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 matches 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 winding body 51 across the direction along the axis.

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

The arm portion 19 is pushed by a pushing means that moves the swinging tip 77 toward the inside of the winding radius of the winding body 51. As the pushing means, for example, a tension spring 81 is used. The tension spring 81 is connected to the arm portion 19 at one end, and is fixed at the other end by a spring support post 83 fixed to the base portion 11. The tension spring 81 is erected on the arm portion 19 and the spring support post 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 pull-out force of the zipper tape 35 caused by pinching the roller 59. That is, the pull-out force of the pinch roller 59 does not cause the roller 79 to float from the winding outer peripheral surface of the winding body 51. In addition, the pushing means may be constituted by a pneumatic cylinder. By using a pneumatic cylinder, the pressing force of the roller 79 on the winding outer peripheral surface of the winding body 51 can be adjusted, for example, the roller 79 can be pressed with an optimal pressure according to the type or material of the wound tape .

In the tape feeding device 100, a winding diameter detection sensor 85 that detects the winding diameter of the winding body 51 is provided across the swing support shaft 75 and the arm portion 19. The rotation support portion 13 controls the rotation driving speed in accordance with the detection value of the winding diameter detection sensor 85. That is, the device control unit checks the winding diameter of the winding body 51 by 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 by the swing angle of the arm 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 roller is installed. In the drum 15, the fastener tape 35 is wound so that the flat surface is parallel to the outer circumference of the bobbin 37. 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 19 swings to a position where it does not interfere with the drum 15 and is retracted. The drum 15 is attached to the required number of layers installed on the rotary table 31.

FIG. 5 is an explanatory diagram of the operation when the arm is installed. After the installation of the drum 15 of the turntable 31 is completed, the winding outer peripheral surface of the winding body 51 is pressed by the arm 19.

Fig. 6 is an operation explanatory diagram of the step of inserting the guide ring of the tape. Rotate the drum 15 toward the feed direction manually, etc., so that the start end of the fastener tape 35 passes through the guide ring 61. In this embodiment, the upper roller 15 will be the initial roller 15. Next, the delivery start end 55 of the winding body 51 of the drum 15 wound around the upper layer passes through the guide ring 61. The zipper tape 35 passing through the guide ring 61 is pinched by the pinch roller 59. After the start end of the zipper tape 35 is subsequently slacked in the temporary storage box 69, it is hung on the transport roller 73 and introduced into the supply mechanism of the bag making machine.

In this state, the adjacent drum 15 is the delivery terminal 53 of the winding body 51 of one drum 15, and is connected to the delivery start end 55 of the winding body 51 of the other drum 15 via the connecting portion 57. That is, the delivery terminal 53 of the upper drum 15 is connected to the delivery start end 55 of the lower drum 15 via the connecting portion 57. As a result, the tape-dispensing device 100 completes preparations before the operation.

The tape feed-out device 100 stands by in a stopped state while the tape detection sensor 71 detects the zipper tape 35 housed 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. When receiving the empty signal of the zipper tape 35, the device control unit drives the rotary table 31 and the pinch roller 59. The device control unit sends out the zipper tape 35 dropped from the pinch roller 59 in the temporary storage box 69 for a certain amount, and then sends out to stop the pinch roller 59 and the rotary table 31, and the standby until the next tape replenishment Status control signal.

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

Fig. 8 is an explanatory diagram of the operation when the drum is switched. The zipper tape 35 pulled out by the pinch roller 59 is continuously pulled out by the connecting portion 57 connected to the delivery terminal 53 of the initial drum 15 to the delivery start end 55 of the drum 15 of the next layer. As a result, the zipper tape 35 ends the transfer from the initial drum 15 to the drum 15 of the next layer.

Fig. 9 is an explanatory diagram of the operation when a new drum starts to be delivered after the drum is switched. As the zipper tape 35 moves along with the transfer of the drum 15, the connecting portion 57 passes through the connecting portion detection sensor 63. The device control unit drives the lifting mechanism 65 so that the lifting mechanism 65 arranges the traction unit 17 to the position corresponding to the drum 15 of the next layer when the connecting portion detection sensor 63 detects the connecting portion 57. In the present embodiment, since the initial drum 15 is the upper layer, the elevating mechanism 65 lowers the pulling portion 17 to the position of the lower drum 15. Thereby, the transfer operation of the drum 15 is all finished.

Next, the operation of the aforementioned configuration will be described. In the tape feed-out device 100 of the present embodiment, the drum 15 around which the fastener tape 35 is wound, the shaft 29 is supported by the rotation support portion 13 through the through hole 41. The fastener tape 35 is wound around the drum 15 so that the tape width direction becomes a direction along the vertical direction, that is, the longitudinal direction.

If the zipper tape 35 is tightly wound, there is a risk of permanent deformation of the product. On the other hand, if the winding of the fastener tape 35 is slack, especially if the fastener tape 35 is likely to slip, it may slip in the width direction due to the action of gravity, which may easily cause the winding to loosen.

In the tape feed-out device 100, the winding body 51 in a slack winding state that does not cause permanent deformation in this way is sent out while pressing the winding outer peripheral surface with the arm 19. That is, the fastener tape 35 can suppress the slip in the width direction due to gravity by the arm portion 19. Therefore, in the tape feeding device 100, the fastener tape 35 can maintain a good shape without permanent deformation, and can be smoothly fed out without entanglement, twisting, or bending.

In this tape feeding device 100, when the drum 15 rotates, on the winding outer peripheral surface of the winding body 51 wound around the drum 15, the roller 79 supported by the roller center in the same direction as the shaft 29 Tie belt rotates. Therefore, the fastener tape 35 and the roller 79 of the winding outer peripheral surface of the winding body 51 do not slide relatively. The winding body 51 can be pressed in such a manner that the fastener tape 35 is not rubbed by the swinging tip 77 of the arm portion 19 even during rotation. Therefore, the arm portion 19 can suppress winding looseness so as not to damage the fastener tape 35.

In addition, in the tape feeding device 100, the arm portion 19 that is swingably supported by the swing support 75 is directed toward the inner side of the winding radius of the winding body 51 by means of a push spring Push in the direction of movement. That is, the arm portion 19 presses the winding outer peripheral surface of the winding body 51 by the pressing force to suppress the winding looseness. In the case of using a spring for tension, 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. As a result, it is possible to strongly press the winding body 51 having a large outer diameter, which is more likely to loosen winding than a person with a small outer diameter. In addition, in the case where a pneumatic cylinder is used as the pushing means, even if the winding diameter changes, the pressing force on the winding body 51 can be controlled to be suitable for the pressing force of the diameter to be pressed. Therefore, it is possible to give the arm portion 19 an appropriate pressing force that does not cause winding looseness.

In addition, in this tape feeder 100, a plurality of pressing portions caused by the swinging front end 77 of the arm portion 19 are provided at regular intervals along the winding outer peripheral surface of the winding body 51. Therefore, the winding body 51 of the drum 15 can suppress the unwinding of the winding more uniformly than the configuration in which the plurality of swinging front ends 77 press the winding outer peripheral surface at unequal intervals. Therefore, the circumferential interval of the winding body 51 pressed by the arm portion 19 can be made uniform and small, and loosening of the winding is less likely to occur.

In addition, in this tape-type feeding device 100, the fastener tape 35 can be continuously sent out in the order of the stacked rollers 15. Therefore, as compared with the configuration in which the drum 15 is individually installed and the zipper tape 35 is fed out, the tape-type feeding device 100 can eliminate the stop time required for drum replacement and improve the operation efficiency. Therefore, it is possible to increase the continuous operation time during bag making using the drum 15 wound with the zipper tape 35.

In addition, in the tape feeding device 100, the delivery terminal 53 of the zipper tape 35 wound around the adjacent one of the drums 15 is connected to the other drum wound on the other side through the connecting portion 57 The delivery start end 55 of the zipper tape 35 of 15. Therefore, at the same time when the delivery of one of the fastener tapes 35 is completed, the delivery of the fastener tape 35 to the next drum 15 can be transferred. Therefore, the fastener tape 35 can be continuously sent out from the drum 15 where the delivery has been completed to the drum 15 where the delivery starts. That is, the drum 15 can be operated continuously for two rolls, and if it is the roll length described above, it can be continuously operated for an amount of 4000 m × 2 = 8000 m.

In addition, in this tape-type feeding device 100, the aforementioned connecting portion 57 is detected, thereby driving the elevating mechanism 65 to move the pulling portion 17 to a position corresponding to the drum 15 for the next feeding. Thereby, even when the drum 15 is stacked in multiple layers, the distance or inclination of the drum 15 and the pulling portion 17 can be kept constant, and the fastener tape 35 can be smoothly sent out. Therefore, it is possible to suppress the inclination between the drum 15 and the pulling portion 17 that sent out the fastener tape 35, so that the fastener tape 35 is less likely to be entangled, twisted, or bent.

In addition, in the tape feeding 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 The diameter of 51. The position of the winding outer peripheral surface of the winding body 51 can be detected by, for example, the swing angle of the arm portion 19 where the swinging tip 77 contacts the winding outer peripheral surface. The tape feed-out device 100 controls the number of revolutions of the rotation support portion 13 so that the feed amount of the fastener tape 35 becomes constant by 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 driving speed of the rotation support portion 13 can be controlled in accordance with the outer diameter of the winding body 51, whereby the fastener tape 35 can be conveyed to the traction portion 17 by a certain delivery amount.

Therefore, according to the tape feed-out 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 around the drum 15.

However, one or two arms or three or more arms may be provided in the circumferential direction. In addition, the interval between the arm portions may be arranged at different intervals in the circumferential direction around the rotation center of the drum 15 as described above. In addition, the number of installation layers of the drum may be one layer, or three or more layers. In addition, the tape type feeding device may be provided with a plurality of rotating tables at the base. At this time, the tapes that can be used for all the rollers are connected in series by the connecting portion, thereby enabling continuous operation.

In addition, in the foregoing embodiment, although the example in which the roll 15 is unwound from the upper layer of the two-layer drum 15 and is fed out and connected to the lower layer has been described, the roll 15 for the lower layer is unrolled and sent out to the upper layer The order of the drum 15 may be sufficient. At this time, it is preferable that the delivery terminal 53 of the fastener tape 35 wound around the lower drum 15 is located at the upper end of the bobbin 37. In the lower drum 15, the bobbin portion 37 is about to arrive at the delivery terminal 53 and the remaining zipper tape 35 will be unwound from the lower portion of the bobbin portion 37 to the vertical upper side, so that the zipper tape 35 will not be The weight is shifted toward the loosening direction and is not easily entangled, so it can be smoothly sent out and transferred to the upper drum 15 through the connecting portion 57.

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

In addition, the clamp body 125 clamps the vicinity of the connecting portion 57 of the fastener tape 35 by a spring force. This clamping force is small, so that the zipper tape 35 can be maintained in a state where tension is applied to the extent that the winding is not loosened, and the degree to which the zipper tape 35 can be easily detached from the clamping state 125 when the zipper tape 35 is pulled Temporarily fixed state.

In the tape feed-out device 200 configured in this manner, first, the roller 15 winds the fastener tape 35 such that the flat surface is parallel to the outer periphery of the bobbin portion 37, and the roller 15 is attached to the axis 91 of the rotary table 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 rotary table 31 are fitted into the recess 40 formed in the flange 39 a of the drum 15. In the case where 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 previously installed on the turntable 31. Next, the connecting block 42 is fitted into the concave portion 40 of the flange portion 39 a of the lower drum 15, and the roller 15 is further superimposed on the drum 15, and the concave portion 40 that becomes the upper drum is fitted into the connecting block 42 to make the drum Become connected to each other. Then, the vicinity of the connecting portion 57 between the delivery terminal of the zipper tape 35 of the upper drum 15 and the delivery start end 55 of the zipper tape 35 of the lower drum is clamped by the clamp 125 of the holding portion 121 (see 14 Figure).

Immediately after the installation of the drum 15 of the turntable 31 is completed, the winding loosening prevention portion 115 is operated at the lower layer and the upper layer, and the winding body 51 is supported from the outer peripheral surface by the bending plate 117.

The drum 15 is rotated in the feed direction by manual operation or the like, and the starting end of the fastener tape 35 passes through the vertical guide roller 103 and the horizontal guide roller 101. In the second embodiment, the upper roller 15 becomes the initial roller 15. Next, the delivery start end 55 of the winding body 51 of the drum 15 wound around the upper layer is passed. The fastener tape 35 that has passed through the guide rollers 103 and 101 is pinched by the pinch roller 59 via the support roller 97 and the slack prevention roller 99 of the slack prevention mechanism 95. The slack prevention roller 99 is equipped with a weight, and at the position of the slack prevention roller 99, the fastener tape 35 will be in a reversed state in the downward direction and the upward direction. The start end of the fastener tape 35 that has passed the pinch roller 59 is hooked to the support roller 109 and the tension adjusting roller 111 of the conveyance amount control unit 107, and then introduced into the supply mechanism of the bag making machine. In this conveyance amount control unit 107, the fastener tape 35 also positions the tension adjusting roller 111 downward and turns into a folded state.

As a result, the tape-dispensing device 200 has completed preparations before the operation.

The tape feeding device 200 causes the pinch roller 59 to stand by while the zipper tape 35 is detected by the zipper recognition sensor 133 by the tension adjustment roller 111 of the conveyance amount control unit 107. As the bag making machine performs bag making, the zipper tape 35 is pulled out from the conveyance amount control unit 107 and the tension adjusting roller 111 rises, the zipper recognition sensor 133 cannot detect the zipper tape 35, and the device control unit receives the signal, Thus, the pinch roller 59 is driven.

The device control unit drives the zipper tape 35 out of the slack prevention mechanism unit 95 by driving the pinch roller 59. The delivery start sensor 135 provided in the slack prevention mechanism 95 detects the position of the slack prevention roller 99 as an ascending or descending position, and if the ascent of the slack prevention roller 99 is detected, the rotary support 13 is driven to perform Rotation starts the sending of the fastener tape 35. By the detection of the zipper identification sensor 133 and the delivery start sensor 135, the traction unit 17 and the rotation support unit 13 are driven, and the zipper tape 35 is delivered to the bag making machine.

The rotary table 31 and the pinch roller 59 repeat the aforementioned intermittent operation, and when the winding body 51 of the drum 15 becomes the minimum winding diameter, the fastener tape 35 is removed from the bobbin portion 37.

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

As the fastener tape 35 moves along with the drum 15, the connecting portion 57 passes through the connecting portion detection sensor 63. The device control unit causes the lift mechanism 65 to arrange the slack prevention mechanism unit 95, the traction unit 17, and the conveyance amount control unit 107 to the roller 15 corresponding to the next layer when the connection unit detection sensor 63 detects the connection unit 57 The position mode drives the lifting mechanism 65. In the second embodiment, since the initial drum 15 is the upper layer, the lifting mechanism 65 lowers the parts 17, 95, 107 to the position of the lower drum 15. Thereby, the transfer operation of the drum 15 is all finished.

Next, the operation of the aforementioned configuration will be described. In the tape feed-out device 200 of the second embodiment, similar to the tape feed-out device 100 of the first embodiment described above, the drum 15 with the zipper tape 35 wound around it, the shaft 29 is inserted through the through hole 41 or The upper and lower rollers 15 are connected by the connecting block 42 and supported by the rotation support portion 13. The fastener tape 35 is wound around the drum 15 so that the tape width direction becomes a direction along the vertical direction, that is, the longitudinal direction.

If the zipper tape 35 is tightly wound, there is a risk of permanent deformation of the product. On the other hand, if the winding of the fastener tape 35 is slack, especially if the fastener tape 35 is likely to slip, it may slip in the width direction due to the action of gravity, which may easily cause the winding to loosen.

In the tape feed-out device 200, the winding body 51 in a slack winding state that does not cause permanent deformation in this way is sent out while applying tension through the slack prevention mechanism portion 95. That is, the slack preventing roller 99 of the slack preventing mechanism portion 95 is lowered by gravity, whereby the fastener tape 35 is pulled from the drum 15 to the pinch roller 59 of the traction portion 17 without slack, while being supported by controlling rotation The sending speed of the unit 13 suppresses slack. Therefore, in the tape feeding device 200, the fastener tape 35 can maintain a good shape without permanent deformation, and can be smoothly sent out with proper tension without entanglement, twisting, or bending.

In addition, in this tape-type feeding device 200, the fastener tape 35 can be continuously sent out in the order of the stacked rollers 15. Therefore, compared with the configuration in which the drum 15 is individually installed to feed out the zipper tape 35, that is, the configuration in which the drum 15 is operated individually, the stoppage time required for drum replacement can be eliminated to improve the operation effectiveness. Therefore, it is possible to increase the continuous operation time during bag making using the drum 15 wound with the zipper tape 35.

In addition, in this tape feeding device 200, the delivery terminal 53 of the zipper tape 35 wound around the adjacent one of the drums 15 is connected to the other drum wound around the other by the connecting portion 57 The delivery start end 55 of the zipper tape 35 of 15. Therefore, at the same time when the delivery of one of the fastener tapes 35 is completed, the delivery of the fastener tape 35 to the next drum 15 can be transferred. Therefore, the fastener tape 35 can be continuously sent out from the drum 15 where the delivery has been completed to the drum 15 where the delivery starts. That is, the drum 15 can be operated continuously for two rolls, and if it is the roll length described above, it can be continuously operated for an amount of 4000 m × 2 = 8000 m.

In addition, in this tape feeding device 200, the connecting portion 57 between the fastener tapes 35 wound around the adjacent rollers 15 is held by the clip 125 of the holding portion 121, and the fastener tape 35 between the rollers 15 It is not easy to slack when sending out, and it is not easy to make the winding loose. Moreover, since the fastener tape 35 is clamped temporarily by the clamp 125, it can be easily detached by the force of the traction unit 17 or the slack prevention mechanism 95 when the part of the connecting portion 57 is sent out. With this, the zipper tape 35 is smoothly sent out.

In addition, in this tape-type feeding device 200, the aforementioned connecting portion 57 is detected, thereby driving the elevating mechanism 65, and the pulling portion 17 and the like are moved to a position corresponding to the drum 15 for the next feeding. Thereby, even when the drum 15 is stacked in multiple layers, the distance or inclination of the drum 15 and the traction portion 17 can be kept constant, and the fastener tape 35 can be smoothly sent out. Therefore, it is possible to suppress the inclination between the drum 15 and the pulling portion 17 that sent out the fastener tape 35, so that the fastener tape 35 is less likely to be entangled, twisted, or bent.

In addition, in this tape-dispensing device 200, a slack prevention mechanism 95 is arranged between the rotation support portion 13 on the side where the zipper tape 35 is sent out and the pulling portion 17 on the side where the zipper tape 35 is pulled, so that the fastener tape 35 Since the slack prevention roller 99 as a tension adjusting roller, tension is applied even if a speed difference occurs between the rotation support portion 13 and the traction portion 17, and if the conveying side becomes faster, the slack prevention roller 99 is lowered 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, and if it is lowered, the speed of the rotary support portion 13 as the conveying side is lowered, and if it is raised, the speed is increased Ascending, in addition, the traction speed of the traction unit 17 is also controlled, thereby enabling stable delivery control.

Therefore, according to the tape feed-out device 200 of the second embodiment, it is possible to suppress entanglement, twisting, and bending caused by loose winding of the zipper tape 35 wound around the drum 15 and to suppress slack between the traction portions 17 .
