Therefore, when the chuck mechanism grips an object to be transported such as an electronic component and moves the moving object, and the belt is released from the fixing mechanism at an arbitrary point,
Since the moving body can be stopped regardless of the movement of the belt, the conveyed object can be gripped or released at the stopping point, and the conveyed object can be conveyed from any point to any desired point. can.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

1 to 5 show embodiments of the conveying device of the present invention.

As shown in FIGS. 1 and 2, a pair of first rollers 4A, 4B, 4C, and 4D having flanges on their end surfaces are rotatably attached to the side surface of the moving body 2. The distance between these rollers 4A, 4B and rollers 4C, 4D corresponds to the vertical width of a single rail 6 installed at the moving location of the moving body 2 and having sliding surfaces forming parallel surfaces on the top and bottom sides. are doing. Therefore, the moving body 2 has four rollers 4A, 4B,
4C and 4D, it is movably installed on the rail 6.

Furthermore, a fixing mechanism 10 as a fixing means for fixing the movable body 2 to the moving belt 8 is provided on the side surface of the movable body 2 . That is, a pulley 18 is rotatably attached to a rotary arm 16 that is rotatable about a support shaft 14 with respect to a second roller 12 protruding from the side surface of the movable body 2. A circular belt 8 is inserted between a roller 12 and a pulley 18. As shown in FIG. 3, a spring 20 is installed between the rotating arm 16 and the movable body 2 to bias the rotating arm 16 clockwise in the figure. Belt 8 is held between roller 12 and pulley 18 by force.

Further, as shown in FIG. 3, a locking claw 22 as a locking means is provided on the contact surface of the pulley 18 with the belt 18. Therefore, the moving body 2 is normally fixed to the belt 8.

A chuck mechanism 28 is provided between the side walls of the movable body 2 to grip a part of the object 24 to be transported such as an electrolytic capacitor, for example, a lead portion 26. That is, as shown in FIG.
A chuck piece 32 is attached to the support shaft 30 provided between the side walls of the
A, 32B are rotatably attached, and the transported object 24
Insert the spring 34 between the sides that do not grip the
The conveyed object 24 is gripped by the biasing force. In this case, in order to elastically grip the conveyed object 24 and ensure gripping by friction, the gripping portions 3 of the chuck pieces 32A, 32B
6, an elastic body 38 is attached. Further, the chuck pieces 32A, 32B are provided with adjustment screws 4 relative to a stopper 40 provided in the center of the movable body 2.
2 is attached, and by adjusting the amount of protrusion of the adjusting screw 42, the distance between the chuck pieces 32A and 32B can be adjusted as desired.

Therefore, when conveying the conveyed object 24 using such a conveying device, when the belt 8 is moved in the direction shown by the arrow A, as shown in A in FIG. The moving body 2 moves on the rail 6 according to the movement of its belt 8.

Then, the stop position of the movable body 2 is set, and at the stop position, the stopper 44 is made to protrude in the direction shown by arrow B and come into contact with the rotating arm 16, thereby restraining the movement of the movable body 2. In this case, rotating arm 1
When the stopper 44 is brought into contact with the belt 6, the rotary arm 16 rotates counterclockwise against the urging force of the spring 20, as shown in FIG. 5B, so that the pulley 18 separates from the belt 8. As a result, the movement of the moving body 2 is reliably stopped, and as long as the stopper 44 is in the protruding state, the stopped state of the moving body 2 continues.
If the pulley 18 comes into contact with the belt 8, the pulley 18 rotates as the belt 8 moves, and in this embodiment rotates clockwise.

Then, as shown in C of FIG. 5, the lower side of the chuck piece 32A is moved in the direction of arrow C with respect to the stopped movable body 2 using the operating rod 46 or the like. The chuck piece 32A is indicated by arrow D.
The grip portion 36 can be opened by rotating in the direction shown in FIG. After inserting a part of the object 24 such as an electrolytic capacitor, in this case the lead part 26, into the opened grip part 36 from the direction of arrow E, and releasing the operation with the operating rod 46, as shown in FIG. As shown in D, the conveyed object 24 can be gripped by the gripping section 36.

The movable body 2 holding the conveyed object 24 is fixed to the moving belt 8 via the fixing mechanism 10 by releasing the protrusion of the stopper 44, as shown in FIG. 5E. According to the moving direction of the belt 8, the conveyed object 24 can be conveyed.

In the embodiment, a single moving body 2 has been described, but a plurality of moving bodies can be fixed to the belt 8 and moved, and in that case, a large number of moving bodies are fixed to the belt 8. Sometimes, even if one moving object is stopped, as long as the belt is moving,
The object to be transported 24 can be transported by moving another moving body.

Further, in the embodiment, a state in which the transported object 24 is gripped upward has been described, but the gripping portion 36 can also be set on the lower side and the transported object 24 can be gripped downward and transported. There is no need for a reversing mechanism such as the conveyance device used in the above.

〔Effect of the invention〕

As explained above, according to the present invention, the following effects can be obtained.

(a) With a simple configuration, objects to be transported can be easily transported.

(b) The moving body can be made extremely small, allowing small objects to be transported in a narrow space, and the device itself can be miniaturized.

(c) The moving object can be stopped at any position, and the stopping position can be set accurately, so the positioning accuracy is high.

(d) The movable body is fixed to the flexible belt using a fixing mechanism consisting of a pulley and a second roller, and the moving force of the belt is releasably transmitted to the movable body, thereby reducing the flexibility of the belt. The fixing mechanism can be elastically fixed due to its flexibility, and since the pulley rotates when fixed, it is possible to suppress friction between the fixing mechanism and the belt, prevent damage to the belt, and maintain a stable conveyance state. I can do it.
