Abstract

(57) [Summary] [Purpose] To provide a carbon terminal that suppresses the generation of sparks. A spring 30 is provided between a strip plate 25 fixed to a spindle 21 via a collar 22 and a movable bar 27 rotatably supported by the spindle 21, and the tension of the spring 30 causes the movable bar 27 to move. 27 and a carbon terminal 32 pivotally supported on the bar via a pin 30 are extruded together in the direction of the rotary terminal 20. [Effect] The sliding of the carbon terminal 32 is not obstructed by the grinding particles generated from the carbon terminal 32.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mechanism for attaching a carbon terminal for transmitting electricity to a rotary terminal of, for example, an electric motor.

[0002]

[Prior art]

 For example, in a packaging mechanism, when electric energy is to be transmitted to a rotary sealer that welds a packaging material intermittently, carbon 2 must always be in contact with a rotary terminal 1 as shown in FIG. In the case of the figure, the main body 4 is firmly fixed to the fixed spindle 3 with bolts and nuts 5 and the carbon 2 is supported by the main body. As shown in FIG. 4, the main body has a rectangular cavity 9 formed in a portion surrounded by a pair of side plates 6 on both sides and a pair of upper and lower plates 7 and 8, and carbon 2 is slidably installed in the cavity 9. The carbon 2 is pressed against the rotary terminal 1 by the pusher 11 on which the pulling force of the spring 10 acts.

[0003]

[Issues to be solved by the device]

 However, there is a drawback that grinding particles generated from carbon 2 enter into the gap between the carbon 2 and the cavity 9 and hinder the sliding of carbon in the cavity. Thus, when the carbon slide lacks agility. , Sparks are generated, and the abrasive particles are solidified to make the carbon slide worse.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned drawbacks, the present invention fixes a support body 26 of a spring to a spindle 21 positioned parallel to the rotary terminal 20, and mounts a movable bar 27 on the spindle 21 on the side of the support body. One end of the movable bar is supported so that the other end of the movable bar is swingable in the direction of the center of the rotary terminal 20, and a carbon terminal 32 is attached to the movable bar via a pin 31 so that the carbon terminal is on the circumferential surface tangent line of the rotary terminal. While being rotatably supported so as to be in contact with each other, an extension spring 30 is provided between the support body and the movable bar.

[0005]

[Action]

 A spindle 30 provided between a main body 26 fixed to a spindle and a movable bar 27 swingably supported by the spindle pushes the movable bar in the direction of a rotary terminal to support a carbon terminal supported by the movable bar. 32 is pressed against the peripheral surface of the rotary terminal 20 and energized. Sliding friction with the rotary terminal 20 causes an inclination stress in the carbon terminal 32 with the pin 31 as a fulcrum, but the tension of the spring 30 opposes the inclination stress of the carbon terminal.

[0006]

【Example】

 As shown in FIG. 1, a spindle 21 having an axis parallel to the axis of the rotary terminal 20 is installed on the side of the rotary terminal 20, and a split collar 22 is fixed to the spindle with a screw 23. The strip plate 25 is fixed to the split collar by the screw 23 and another screw 24, and the spring support body 26 is formed by the split collar and the strip plate. On the other hand, as shown in FIG. A pair of movable bars 27 are swingably supported by the spindle 21 on both sides of the. Further, one end of a guide 29 is supported by a first pin 28 provided on the other ends of both the movable bars, the guide 29 is slidably engaged with a hole formed in the strip 25, and a spring provided along the guide. By the overhanging force of 30, the carbon terminal 32 pivotally supported on the movable bar 27 by the second pin 31 is pressed against the peripheral surface of the rotating terminal 20.

[0007]

【effect】

 The present invention has a structure in which the carbon terminal 32 is pushed out in the direction of the rotary terminal 20 integrally with the movable bar 27 supported by the spindle 21. The disadvantage that the carbon terminal does not move due to the grinding particles generated from the carbon terminal is solved, and the rotation The carbon terminal 32 follows the small eccentric rotation of the terminal 20 and always keeps the surface contact with each other, and has an effect of minimizing the spark generated between the rotating terminal and the carbon terminal.
