Abstract

PURPOSE:To supply works of the normal attitude by forming a separation wall higher from the upper surface of a disc by designated times of thickness of an article, and selecting works in a rotary part feeder for a cap of a milk bottle or the like. CONSTITUTION:A separation wall 3 is formed higher from the upper surface of a disc 1 within the range of 0.5 - 0.8 times of thickness of a work. In this arrangement, only reverse works and overlapping works are made thinner and expanded on one side by the given centrifugal force, so that the works jump over the separation wall 3 to be discharged to the outside of a system. On the other hand, normal works are moved along the separation wall 3 in the state of being locked on the separation wall 3.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to articles that are circular, thin, and have a slight bulge on either the top or bottom, such as a lid inserted into a milk bottle or a washer that is a part of an alkaline manganese battery. The present invention relates to a so-called parts feeder that transports pieces (hereinafter referred to as "works") aligned in a fixed direction without overlapping each other.

BACKGROUND OF THE INVENTION A conventional parts aligning and feeding machine called a revolving parts feeder transports parts fed by a rotating inclined plate toward the circumferential edge, and transfers them onto a rotating outer track provided on the outside of the inclined plate. During the transportation process, a fixed ring-shaped guide separates parts that are oriented in the wrong direction or overlapped from parts that are oriented correctly. The parts separated here in the opposite direction and the overlapping parts are returned to the central part of the parts feeder, and the mechanism is such that the orientation is again sorted.

Problems to be Solved by the Invention However, there is a gap between the outer circumferential track, which is a rotating body, and the fixed ring-shaped guide. Therefore, if it is thin and has a slight bulge on either the top or bottom,
For parts where the forward or reverse orientation cannot be easily determined, a part of the part may get stuck in the gap between the track and the guide, making it impossible for the machine to operate smoothly or for a stable supply of parts. there were.

SUMMARY OF THE INVENTION An object of the present invention is to solve such problems and provide a parts feeder that can select the orientation of the workpieces and send only the uniformly aligned workpieces to the next process.

Means for Solving the Problems In order to achieve the above object, the parts feeder of the present invention includes a fall prevention wall for preventing the workpiece from falling, and a fall prevention wall for preventing the workpiece from falling, on the periphery of the disk that feeds the workpiece to the circumferential side. It is equipped with a forward/reverse separation wall for reverse sorting and removal of overlapping workpieces.

The separation wall here has a thickness in the range of 0.5 to 0.8 times the thickness of the workpiece, and is characterized in that its upper surface protrudes upward from the upper surface of the disk.

By providing a separation wall in this way, even if workpieces are supplied with different orientations, the orientation of the workpieces can be sorted and only the workpieces that are aligned in a certain way can be carried forward to the next process. .

Example Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

The structure of the parts feeder of the present invention includes a disc 1 which is a rotating body.
is rotated by a motor 11. The fall prevention wall 2
, and are surrounded by separation walls 3, and are fixedly supported by brackets 5, which are supports. In addition, the work guide 4 is
It is fixedly supported in a suspended state by a bracket 6 which is a support body.

The work whose orientation is to be sorted is supplied to the center of the disk 1. As shown in the plan view of FIG. 2, the guide 4 is partially cut off, and the work is conveyed in a line to the circumference of the disk by movement from the cut portion as it rotates. In order to prevent the workpiece from getting stuck in the gap between the rotating disk 1 and the fixed guide 4, a groove is provided in the disk 1 with a depth of 2 to 3M, and the tip of the guide 4 is positioned within this groove. The guide 4 is fixedly supported so that its lower end is at a lower position than the upper surface of the disc 1. The workpiece conveyed between the guide 4 and the fall prevention wall 2 is conveyed along the fall prevention wall 2 and reaches the separation wall 3, as shown in FIG. The only workpieces that have been transported up to this point are those that are oriented in the opposite direction or overlapped due to the centrifugal force applied.
Because of its thin thickness and bulging shape on one side, it jumps over the separation wall 3. Then, only the normally oriented workpieces are transported along the separation wall 3 and transported to the exit chute 12 (see FIGS. 4A, B, and C).

The workpiece that has jumped over the separation wall 3 falls into a hopper 22 that receives it, as shown in FIG. Hopper 22
Then, using vibration, the workpieces are sequentially fed and conveyed in fixed amounts to the linear feeder 23 and the ascending conveyor 24. From the ascending conveyor 24, the workpieces are fed and conveyed through a chute 25 to the center of the disk 1 of the parts feeder of the present invention, and the orientation of the workpieces is again sorted.

Effects of the Invention With the parts feeder of the present invention, it is possible to align thin, circular articles with a slight bulge on either the top or the bottom in a fixed direction, which was impossible with conventional parts feeders. It is possible to smoothly feed the parts to the next process in front of the parts feeder.

[Brief explanation of the drawing]

The drawings show an embodiment of the present invention, in which Fig. 1 is a front view of a parts feeder, Fig. 2 is a plan view thereof, and Fig. 3 shows an example in which an article (work) is placed on a fall prevention wall around a disk of the parts feeder; Figures 4A, B, and C show the state of the objects being transported between the guide and the workpieces, which are sorted and separated in the forward and reverse directions and the removal of overlapping objects at the separation wall part of the circumference of the disc of the Bart's feeder. FIG. 5 is a system diagram for putting the parts feeder of the present invention into practical use. 1... Disc, wall, 4... Guy mouth chute, 2
