Abstract

PURPOSE:To enable efficient orderly conveyance by providing a downwardly inclined upper wall part on one side, in the conveying direction, of a device which orderly conveys a part such as a minimold transistor, etc. having a projected pars such as an electrode, etc. of different length on each side, and conveying said part in an orderly way utilizing the length of said projected part. CONSTITUTION:When a number of parts 1 are thrown into a bowl 6 of and a torsional vibration is provided, the parts 1 ascend the spiral track 7 of the bowl 6 in a random posture respectively and are introduced in a line into the transferring surface 24 a of a part orderly conveyance device 8. In this case, if the electrodes 3a, 4a of a part 1 are faced downward, the part 1 is inverted with its own weight and falls on a pocket 22 since the electrode 3a or 4a is slidingly brought in contact with the transferring surface 24a. Also, a part 1, which is introduced upside down with its shorter electrode 4a being inwardly directed, falls in the similar way. On the other hand, a part which is introduced upside down with its longer electrode 3a being directed inward, is prevented from being invert since the electrode 3a is brought in contact with the upper wall part 25a of a block 25, and the part is transferred with the same posture.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a parts sorting device in a vibrating parts feeder.

A vibrating parts feeder is generally called a parts feeder, and in most conventional parts feeders, parts on the track are transferred by applying torsional vibration to a bowl-shaped container (ball) that has a spiral track inside. The parts are then fed to the next process from the end of the track, but in this case they are usually required to be fed in a constant posture. For this purpose, various sorting devices have been developed depending on the shape and properties of the parts to be supplied.
None of the components (1) shown in the figures and FIG. 2 perform sorting, or have very low sorting efficiency. That is, the component (1) shown in FIGS. 1 and 2 is a mini-mold transistor, and the component on the side is extremely small, and a large amount of it is inserted into the ball. These parts (
1) is fed in the direction of the arrow on the transfer path with the long electrode (3a)'z pointing upward and to the left in the transfer direction. delivery was impossible or insufficient.

The present invention has been made in view of the above-mentioned points, and provides an efficient component having at least one first protrusion in the lower part of one side and at least one second protrusion longer than the first protrusion in the lower part of the other side. It is an object of the present invention to provide a parts sorting device for a vibrating parts feeder that allows for good sorting. According to the present invention, this purpose is to move the parts on the transfer path by vibration, and to form an earthen wall portion having a predetermined width above the path, -
Among the parts having at least one first protrusion on the lower part of the side surface and at least one second protrusion part longer than the first protrusion part on the lower part of the other side, the other side surface is connected to the transfer path in an upside down position. The parts transferred in the above-mentioned side direction bring the second protrusion into contact with the upper wall part and proceed as they are, and all the parts in other positions are at the edge of the transfer path. This is accomplished by a parts sorting device characterized in that the components are removed from the transfer path by the reversing action of gravity.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A parts feeder equipped with a parts sorting device according to an embodiment of the present invention will be described below with reference to all the drawings.

Further, a block (c) for forming a thin earth wall is fixed on top of 241. Transfer path forming block (for 24+, parts (
A transfer surface (24a) having a width slightly smaller than half the width of the body (2) in (1) and (5) a slope (24b) serving as a transfer path side wall are formed. The transfer surface (24a) is inclined downwardly toward the inside of the ball as shown. On the other hand, the track of the ball (6) (
7) Although the track (7) is inclined outwardly and downwardly, the inclination angle of the transfer surface changes continuously at the discharge end of this track (7), and the inclination angle becomes the block (transfer surface (24a) of 24). A slope (25a) is formed at the outer corner of the block for forming a thin earth wall (c).
This width is determined in consideration of the difference in length between one electrode (4a) and the other electrode (3a) of component (1).

It consists of an arc-shaped bottom wall forming block c! 6 (as shown in FIG. 8) and a pair of left and right arc-shaped presser blocks (2) fixed thereto. The presser blocks (27) (281) are arranged at predetermined intervals,
