Description

  The present invention relates to a blade machine carrier used in a blade machine (braiding machine) for braiding a plurality of wire rods on the outer periphery of a core material such as a tube.

  Conventionally, a blade machine for braiding a wire such as a wire on the outer periphery of a core material such as a tube is provided with a plurality of carriers so that it can run along a continuous 8-shaped running groove provided on the face plate. The outer periphery of the core material is braided by feeding the wire material upward from each bobbin provided on the carrier.

  As shown in FIG. 2, the carrier used in the above blade machine has two tension rods 21 a and 21 b provided apart from each other on the left and right sides, and is fixed between the upper bracket 22 and the lower base plate 23. The respective tension rods 21a and 21b are provided with sliding members 25 and 25 each having a tension roller 24 therebetween. Further, one tension rod 21b shown on the right side of FIG. 2 is provided with a long coil spring 26 between the sliding member 25 and the bracket 22, and a downward elastic force against the tension roller 24 pulled upward. Is to be energized. Further, a stopper 28 fixed by a screw 27 is provided at a substantially intermediate position of the other tension rod 21a, and a weight 30 is slidable on the tension rod 21a via a coil spring 29 supported by the stopper 28. An intermediate roller 32 is provided on the weight 30 via a support piece 31.

  In such a configuration, a bobbin shaft (not shown) is rotatably provided on the bobbin shaft 39 provided in the vicinity between the tension rods 21a, 21b on both sides, and the wire W drawn from the bobbin is pulled out according to the drawing position. The wire W is guided while changing the vertical position of the intermediate roller 32. Then, the wire W is hung on the tension roller 24 and is drawn upward from the outlet 34 through the base roller 33 provided on the upper portion of the upper bracket 22, and the outer periphery of the core material (not shown) performed above the wire W To be supplied for braiding work.

  In such a wire W supply operation, the wire W is always pulled upward via the tension roller 24, and this pulling force acts as a force pulling the two tension rods 21a and 21b upward. Further, when the wire W is braided, twisting or vibration is generated by rotating the carrier 20 while the carrier 20 is traveling. Therefore, when the fixing force of the tension rods 21a and 21b with respect to the base plate 23 is weak, there is a disadvantage that the tension rods 21a and 21b come off from the base plate 23.

  For this reason, conventionally, various devices have been made to the structure for attaching the tension rods 21 a and 21 b of the carrier 20 to the base plate 23. As the structure, first, as shown in FIG. 2, bosses 35, 35 are fixed to the left and right of the base plate 23, and the tension rods 21a are inserted into the bosses 35, 35 and the through holes 36, 36 provided in the base plate 23, respectively. In the state where the lower end portion of 21b is inserted, screws 37, 37 are fastened to screw holes 35a, 35a provided on the side portions of the bosses 35, 35, and the lower end portions of the tension rods 21a, 21b are attached to the base plate 23. The means of fixing by welding 38 was employed.

  However, even with such a fixing means, the welds 38 at the lower ends of the tension rods 21a and 21b are peeled off by the force that pulls the tension rods 21a and 21b upward, twisting, vibration, etc. The problem of the tension rods 21a and 21b coming out of the through holes 36 and 36 due to loosening has not been solved.

  Therefore, in order to further strengthen the fixing force of the tension rod, a fixing means as shown in FIG. 3 has been employed. The carrier 40 shown in FIG. 3 has the same basic structure as the carrier 1 shown in FIG. 1, and details thereof will be described in the embodiment of the present invention. The fixing means drives the left and right tension rods 41, 41 of the carrier 40 into the base plate 42 and the through holes 44 provided in the bosses 43, 43, and fixes them by press fitting. In this structure, the bosses 43 are fixed to the upper portions of the 43 by welding 45.

  However, even with such a structure, the welds 45 at various places are peeled off, and the right and left tension rods 41, 41 come out of the respective through holes 44.

In addition, as a result of the investigation, it has been impossible to find an appropriate technical document for solving such a problem, but there is an invention shown in Patent Document 1 as an example. The present invention improves the bearing mechanism of a conventional bobbin carrier bobbin bearing in order to prevent the rotation of the carrier bobbin from oscillating as the bearing wear progresses, and the frequency of disconnection to increase rapidly. However, the present invention is not intended to fix the tension rod and the base plate of the carrier which is a problem of the present invention, and is not helpful in solving the problems of the present invention.
