Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for separating a continuous component one by one in a transport path for transporting a large number of components linearly and continuously in a substantially horizontal direction.

Problems to be Solved by Conventional Techniques and Inventions Conventionally, an apparatus for separating a plurality of parts one by one in a conveyance path for conveying a large number of parts in a straight line in a substantially horizontal direction. Is a movable body disposed freely above the transport path in a direction perpendicular to the transport path,
The two blocking plates, each of which has a wedge-shaped tip portion, are oriented in the direction perpendicular to the conveying path and are spaced apart from each other by one component in the conveying direction of the conveying path. Attached so as to substantially match, normally the front side of the component at the most distal position on the transport path is projected on the front side blocking plate to block each component, and the moving body is driven in one direction, By retracting the front blocking plate to the side and advancing the rear blocking plate to insert it into the front side of the component located second from the tip, the blocking of the most advanced component is released. The second and subsequent parts are transported by the transport path and blocked by the rear blocking plate, and then the moving body is driven in the opposite direction to move the front blocking plate forward and the rear side. By retracting the blocking plate of The product moves forward and is blocked by the front blocking plate. By repeating the above operation at a predetermined time interval, continuous parts are separated one by one. However, in such a device, a drive mechanism for moving the moving body forward and backward is required, which complicates the device, and a cutting-edge component whose blocking by the blocking plate on the front side is released is However, it has a drawback that it does not have a certain accuracy because it only moves forward due to the carrying force of the carrying path.

Means for Solving the Problems The present invention is, as a means for solving the above problems, rotatively driven in one direction above a conveying path that conveys a large number of parts in a straight line in a substantially horizontal direction. The hollow feed drum, whose axial center direction is substantially parallel to the conveying direction, is supported by a supporting plate having a notch so that the outer peripheral surface is close to the upper surface of the conveying path, and the rear end surface of the feed drum is provided. The front end of the feed drum is formed so that the parts come into contact with each other, and an introduction port into which the part fits is formed on the rear end surface of the feed drum and the part corresponding to the cutout portion of the support plate of the feed drum communicates with the introduction port. A passage is formed for the component that is opened in the surface, and an inclined feed surface that forms an acute angle with the rear end surface of the feed drum is formed at the rear side edge of the passage in the rotation direction of the feed drum.

The action and effect of the invention The component separating device in the component continuous conveying path of the present invention has the above-described configuration, and the inlet of the feed drum rotating in one direction is aligned with the most advanced component that was in contact with the rear end surface of the feed drum. When the part is fitted into the inlet, the second part is then inserted by the front part of the part where the abutting part of the rear end surface of the feed drum and the inclined feed surface make an acute angle. The part that is in contact with the rear end surface of the feed drum and that is fitted into the inlet is pushed forward in the passage by the engagement with the inclined feed surface of the passage formed on the outer peripheral surface of the feed drum, The parts that have been sent out to the front side and are blocked by being abutted against the rear end surface of the feed drum are sequentially separated one by one by the rotation of the feed drum. Direction continuous rotation The drive mechanism is simple because it only needs to be performed, and each component fitted in the inlet is forced by the width of the feed drum at a speed higher than the transport speed of the transport path by engaging the inclined feed surface of the path. Since it can be sent forward forward, the parts can be separated at high speed and reliably, and since the drum is hollow and the passage of the parts is formed in the portion corresponding to the notch of the support plate, If the drum stops due to a failure while the part is in the middle of the passage, the part can be easily taken out.
