Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a conveying device for gripping and conveying electronic components and the like.

[Conventional technology]

BACKGROUND ART Conventionally, when electronic components such as electrolytic capacitors are transported during an assembly process or a boxing process before shipping, the electronic components are transported intermittently using a transport device such as a belt conveyor.

[Problem that the invention seeks to solve]

In such a transport device, if an attempt is made to take out an electronic component from its gripping means at an arbitrary location, it is necessary to stop the entire transport, resulting in a low operating rate.

In addition, in the case of transport devices that grip and transport electronic components, the gripping direction is fixed, and if the vertical direction of the electronic components needs to be changed according to the work, a separate reversing mechanism must be installed. The disadvantage is that the device becomes complicated and large.

For this reason, a transport device that can transport objects such as electronic components with a simple configuration has been proposed. This conveyance device includes a movable body movably mounted on a rail, a gripping means for gripping or releasing the grip of the conveyed object by operation on the movable body, and a belt that moves in the conveyance direction of the conveyed object. A fixing means is provided in which the fixation can be released by restricting the movement of the movable body.

According to such a conveying device, when the gripping means grips an object to be conveyed, such as an electronic component, the movable body is moved, and the movement of the movable body is restrained at an arbitrary location, the fixing means is separated from the belt. Since the moving body can be stopped regardless of the movement of the belt, by gripping or releasing the object at the stopping point, the object can be transported to any desired location.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a conveying device in which the belt and the movable body can be fixed and released with a simple structure.

[Means for solving problems]

As shown in FIG.
A movable body 2 that grips and conveys a conveyed object 24 is installed on the movable body 2, and a rotating arm 12 is mounted on this movable body 2 together with a roller 8.
The flat belt 4 is inserted between the eccentric roller 14 rotatably attached to the rotary arm 12 and the roller 8, and the rotary arm 12 is elastically biased in the direction of gripping the belt 4. The movable body 2 is removably locked to the belt 4.

[For production]

In the conveying device of the present invention, the movable body 2 movably installed on the rail 22 is fixed to the belt 4 by gripping by the roller 8 and the eccentric roller 14 attached to the rotating arm 12. The moving body 2 can be moved by moving the belt 4. Then, by releasing the bias of the rotating arm 12, the eccentric roller 14 is disengaged from the belt 4, and is released from movement by the belt 4, so that the movable body 2 can be stopped at an arbitrary position.
