In this way, the pair of clamp members C and C ′ holding the lower thread Y1 and the upper thread Y2 have the same structure, and the first clampers c1 and c1 ′ and the second clampers c2 and c2 ′ are connected to a common axis f2. The first clamper driving cams c3 and c3 ′ and the second clamper driving cams c8 and c8 ′ are attached to the same drive shaft D and driven by the same motor M. Since the first clamper driving cams c3 and c3 ′ and the second clamper driving cams c8 and c8 ′ are appropriately set, the lower end of the lower thread Y1 and the upper thread Y2 are cut. The position in the horizontal direction with respect to the end can be exactly matched. Further, since the lower thread Y1 and the upper thread Y2 are placed on the reference blocks B1 and B2 having the same upper surface, the lower thread Y1 by the first clamper c1 and the second clamper c6 of the clamp member C The holding position in the vertical direction, in other words, the holding height, and the holding position in the vertical direction of the upper thread Y2 by the first clamper c1 ′ and the second clamper c6 ′ of the clamp member C ′, in other words, the holding height. Therefore, the cut end of the lower yarn Y1 cut by the cutter member S and the cut end of the upper yarn Y2 cut by the cutter member S ′ are accurately abutted with each other. .

It adheres to the butt | matching part of the end and the cutting end of the upper thread Y2. Thereafter, the base p1 is retracted to the standby position.
[0026]
Next, the front end h1 of the ultraviolet irradiation member H is moved to the abutting portion between the cut end of the lower yarn Y1 and the cut end of the upper yarn Y2 to which the ultraviolet curable resin liquid is adhered, and the abutting portion is irradiated with ultraviolet rays. Then, by curing the UV curable resin liquid attached to the abutting portion between the cut end of the lower yarn Y1 and the cut end of the upper yarn Y2, the splicing operation between the lower yarn Y1 and the upper yarn Y2 is completed. Become. Thereafter, the ultraviolet irradiation member H returns to the standby position.
[0027]
After the splicing operation of the lower thread Y1 and the upper thread Y2 is completed, the driving of the motor M is resumed, and the first clamper driving cam c3 and the second clamper driving of the clamp member C for gripping the lower thread Y1. The cutter driving cam s6 of the cutter member S for cutting the cam c8 and the lower thread Y1 is returned to the original standby position shown in FIGS. 4A and 4B, and the upper thread Y2 is gripped. The first clamper driving cam c3 ′ and the second clamper driving cam c8 ′ of the clamp member C ′ and the cutter driving cam s6 ′ of the cutter member S ′ for cutting the upper thread Y2 are set to the original standby position. return.
[0028]

'And the second clamper c6' are pivotally supported on a common shaft f2, and the first clamper c1 and the second clamper c6 of the lower thread clamp member C that grips the lower thread Y1, and the upper thread Y2 are gripped. Since the first clamper c1 ′ and the second clamper c6 ′ of the upper thread clamp member C ′ are configured to rotate around the common axis f2 in a direction approaching each other, the lower thread Y1 The cutting end of the upper thread Y2 and the cutting end of the upper thread Y2 can be accurately matched, and the abutting operation can be performed in a short time.
[0029]
Further, reference blocks B1 and B2 having the same upper surface are disposed so as to sandwich the pair of thread clamping / cutting units U and U ′, and the lower thread Y1 and the upper thread Y2 are connected to the reference blocks B1 and B2. The height of the lower thread Y1 gripped by the lower thread clamp member C and the height of the upper thread Y2 gripped by the upper thread clamp member C ′ are accurately set. Therefore, it is possible to accurately match the cut end of the lower yarn Y1 and the cut end of the upper yarn Y2.
[0030]
Further, a pair of tensors T and T ′ are arranged so as to sandwich the clamp members C and C ′ and the cutter members S and S ′, and the lower thread Y1 and the upper thread 2 are lightened by the tensors T and T ′. Since the gripping is performed in a tensioned state, the lower thread Y1 and the upper thread Y2 can be reliably cut by the cutter members S and S ′.
[0031]
In the above-described embodiments, the ultraviolet curable resin is used as the resin liquid applied to the butt portion, but a thermosetting resin can also be used. In this case, as a matter of course, in order to cure the applied resin liquid, a hot air jet device is used in place of the ultraviolet irradiation member H.
[0032]
In the embodiment described above, an example in which the tensors T and T ′ are disposed is shown. However, as described above, the important functions of the tensors T and T ′ are applied to the clamp members C and C ′. By grasping the clamped lower thread Y1 and upper thread 2 with a tensioner T, T ′ in a slightly tensioned state, the lower thread Y1 and upper thread Y2 are reliably cut by the cutter members S, S ′. Therefore, the lower thread Y1 is sucked and held by the relay pipe, and the upper thread Y2 is sucked and held by the suction mouth, as in the yarn splicing operation in the automatic winder, and the lower thread Y1 and the upper thread Y2 In addition, when a light tension is applied, the upper tensor T and the lower tensor T ′ can be omitted. In such a case, the unnecessary lower yarn Y1 and upper yarn Y2 cut by the cutter members S and S ′ are respectively sucked into the waste yarn duct through the suction mouth and the relay pipe.
[0033]
Further, in the above-described embodiment, the resin liquid supply member P is composed of the syringe-like container p2 and the plunger p3 inserted into the container p2, and the cylinder p5 is operated to move the piston rod p4 to the piston rod p4. Although an example is shown in which the ultraviolet curable resin liquid is discharged from the needle-like tip p2a of the container p2 by advancing the attached plunger p3, the cylinder p5 and the piston rod p4 are shown. And the plunger p3 and the like are omitted, and compressed air controlled by an electromagnetic valve or the like is instantaneously supplied into the container p2 containing the ultraviolet curable resin liquid, and ultraviolet curing is performed from the needle-like tip p2a of the container p2. It can also be configured to discharge the resin liquid.

【The invention's effect】
Since the present invention has the above-described configuration, the following effects can be achieved.
[0035]
A first clamper and a second clamper that constitute a clamp member that grips one thread, and a first clamper and a second clamper that constitute a clamp member that grips the other thread, with a common axis as the center. Since it is made to rotate in the approaching direction, it is possible to accurately match the cut ends of the yarn and to perform the matching operation in a short time.
[0036]
Since a reference block having the same upper surface is arranged so as to sandwich a pair of thread clamping / cutting units, the gripping heights of the clamp members for gripping two threads can be accurately matched. Therefore, it is possible to accurately match the cut ends of the yarn.
[0037]
Since the movable blade rotates in the direction of the fixed blade located on the outside and the movable blade is positioned closer to the cutting end than the fixed blade when the yarn is spliced, the movable blade is fixed. When rotating in the blade direction, a large space is formed between a pair of cutter members arranged side by side, so that there is no hindrance to the resin coating operation or the resin curing operation to the cutting end. Moreover, since the movable blade does not contact the cut end on the side to be abutted after cutting the yarn, the tip end on the side to be abutted does not bend, and therefore the cut ends of the yarn are not matched. It can be performed accurately and reliably.
