DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flexible filament material having a bent portion and a flexible filament material having a bent portion and having a tube mounted thereon. The present invention relates to a material conveying device.

[0002]

2. Description of the Related Art Conventionally, a flexible wire material having a bent portion and a flexible wire material having a bent portion and a tube mounted thereon are known as flexible wire materials. Was pinched by a pair of rubber rollers at a plurality of locations, and was conveyed by rotation of the rubber rollers. In the flexible wire transport device, the wire is twisted because the wire is flexible, and it is difficult to make the bending direction of the bent portion and the direction of clamping by the roller constant. For this reason, the bent portion is often restored and deformed by being pressed from the bending direction of the bent portion by the holding force of the rubber roller.
Further, when the flexible wire having the bent portion formed and the tube attached thereto is conveyed, the bent portion is restored and deformed by the holding force of the rubber roller. Sometimes got out of the way.

The operation of the transporting device for the flexible linear material 18 on which the tubes 18 are formed while the tubes 18b and 18c are formed will be described. The mark tube holder 22 is opened, the mark tube 19 having a specific length is positioned in the mark tube storage chamber 22c, and the mark tube holder 22 is closed. Subsequently, the pair of transport rollers 20 and 21 and the pair of transport belts 16 and 17 are driven in the forward direction (rightward transport of the flexible linear member 18 in the drawing) to move the flexible linear member 18. 1 to 4 (hereinafter, this direction is referred to as a forward direction), and the mark tube 1 in the mark tube holder 22 is transferred.
Pass through 9 holes. When the distal end of the flexible wire 18 has passed through the mark tube holder 22 and has passed the retaining bender 25, the transportation of the flexible wire 18 is temporarily stopped, and both the vendors 25 and 26 are activated. Bending portions 18a and 18b are formed to prevent the mark tube 19 on the distal end side of the flexible linear material 18 from being pulled out and detented.

Next, the mark tube holder 22 is opened,
By driving the pair of transport rollers 20 and 21 and the pair of transport belts 16 and 17 in the forward direction again, the flexible linear material 18 is transported in the forward direction to a specific length, and the flexible linear material 18 is moved. Cut the rear end with a cutter (not shown)
Further, the flexible wire 18 is transported in the forward direction until the rear end of the flexible wire 18 passes through the mark tube holder 22.

Next, the mark tube 19 to be attached to the rear end of the flexible linear material 18 is placed in the mark tube accommodating chamber 22c of the mark tube holder 22, the mark tube holder 22 is closed, and the flexible wire 18 is closed. The mark tube holder 22 is moved to the air rotor
Is rotated by 180 degrees, and the pair of conveyor belts 16 and 17 and the pair of conveyor rollers 20 and 21 are driven in opposite directions (leftward in the figure), so that the rear end of the flexible wire 18 is a mark tube holder. The flexible wire 18 is conveyed until the flexible wire 18 is passed until the flexible wire 18 passes through the flexible wire 18 until the flexible wire 18 is passed. The part 18c is formed.

When the bending process 18c for retaining on the rear end side of the flexible linear material 18 is completed, the mark tube holder 22 is opened, the solenoid 4 is driven, and the substrate 2 is moved to the first shaft 1a.
Of the flexible wire 18
The mark tube 19 attached to the rear end of the lower block 22
After moving upward from b, the pair of transport belts 16 and 17 and the pair of transport rollers 20 and 21 are driven in the forward direction to transport the flexible filament material 18 in the forward direction. During the transport of the flexible wire 18 in the forward and reverse directions, the flexible wire 1
8, each of the bends 18a, 18b and 18c is oriented vertically, and the bends 18a, 18b and 18
c is transported while being sandwiched between the pair of transport belts 16 and 17, and does not receive a vertical force.

When the mark tube 19 mounted on the flexible wire 18 passes between the pulleys 7d and 8d of the pair of conveyor belts 16 and 17, the motor gear 6, the feed gear 7c and the idle gear 8b While the distance between the idle gear 8b and the feed gear 8c does not change, the pair of holding arms 7, 8 swing about the respective shafts 7a, 8a against the tension of the spring 9, and the pulley 7d , 8d open, the pair of transport belts 16 and 17 open, and the rotation of the motor 5 allows the transport of the mark tube 19 to be performed without any trouble.

Similarly, when the mark tube 19 attached to the flexible filament material 18 passes between the pulleys 10d and 11d of the pair of conveyor belts 16 and 17, the pair of paired conveyor belts 16 and 17 resists the tension of the spring 12 when the pair of conveyor belts 16 and 17 is pulled. The holding arms 10, 11 swing about the respective shafts 10a, 11a, and pulleys 10d, 1
Since the interval between 1d is opened, the pair of transport belts 16 and 17 are opened, and the transport of the mark tube 19 is performed without any trouble.
Further, the mark tube 1 attached to the flexible filament 18
9 is a pulley 13d of a pair of transport belts 16 and 17,
14d, the pair of holding arms 13 and 14 are driven by the respective shafts 13a and 13a against the tension of the spring 15.
Since the roller 4a swings around the center 4a and the space between the pulleys 13d and 14d is opened, the pair of transfer belts 16 and 17 are opened, and the transfer of the mark tube 19 is performed without any trouble.

According to the present invention, in a flexible wire transporting device for transporting a flexible wire having a bent portion formed thereon, a pair of flexible wire members sandwiching the bent portion of the flexible wire are provided. Since the transport belts are provided, the pair of transport belts do not press the bending direction of the flexible linear member and transport the flexible linear material across the side of the bent portion, so that the bent portion does not deform. Further, in a flexible wire transporting device for transporting a flexible wire having a bent portion formed and a tube attached thereto, a pair of transporting and transporting devices for sandwiching the bent portion of the flexible wire is provided. Since the belt and the opening / closing means for the conveyor belt are provided, not only the deformation of the bent portion does not occur during the conveyance as described above, but also the conveyor belt is opened in the conveyance of the tube, and the linear material is removed. Since the transport belt closes when it is sandwiched between the transport belts, the transport of the flexible filament material on which the tube is mounted can be performed without any trouble.
