As shown in FIG. 2, the present invention relates to a device that is arranged in a vertically arranged posture.

[0002]

2. Description of the Related Art For example, when manufacturing a chip-type resistor as described in Japanese Patent Application Laid- Open No. 3-183103 , as shown in FIG. A material substrate A formed by integrally connecting a large number of "" is used. A pair of left and right upper electrode films and a resistive film are formed at the location of each chip substrate A "on the upper surface of the material substrate A. then, the material substrate a, 'then a break occurs, the respective rod-shaped substrate a' plurality of rod-shaped substrate a along the horizontal streak eyes B ₁ depends on both longitudinal sides a _1, a ₂ in,
Forming a side electrode film, and each rod-like substrates A ', adopts a method called a break along its longitudinal muscle Looking B ₂ for each chip substrate A ".

When forming side electrode films on the left and right longitudinal side surfaces A ₁ and A ₂ of each of the rod-shaped substrates A ′, the rod-shaped substrates A ′ are arranged side by side as shown in FIG. As shown in FIG. 2, the posture is rearranged vertically, and then the left and right long side surfaces A ₁ ,
To A _2, it employs a method called firing at high temperatures later coated with a conductive paste.

[0004]

However, conventionally, when forming the side electrode film, a plurality of rod-shaped substrates A 'are
As described above, the rearrangement from the horizontally arranged posture to the vertically arranged posture is performed one by one on the bar-shaped substrate A ', so that the work efficiency is low and the cost is greatly increased. There was a problem.

According to the present invention, the rod-shaped substrates can be rearranged simultaneously for a large number of rod-shaped substrates, and the width of the rod-shaped substrates can be easily dealt with. An object of the present invention is to provide a sorting device.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above technical object, the present invention provides a conveyor for transporting bar-shaped substrates in a side-by-side arrangement, provided with a stopper against which the bar-shaped substrates being conveyed by the conveyor contact. In the front portion of the conveyor along the transport direction, a magazine formed by providing a plurality of vertical grooves along the transport direction of the conveyor, in which the rod-shaped substrate fits in a vertical orientation is arranged, On both left and right sides of the conveyor, a pair of left and right scooping members are disposed so as to extend in the conveying direction of the conveyor, and the scooping members are moved upward from below at the positions of the stoppers. After that, an operating mechanism is provided which operates to move to a position above the magazine, then move down to a position below the magazine, and then return to the original position, On the upper surfaces of the two scooping members, a plurality of protrusions for the bar-shaped substrate are provided along the conveying direction of the conveyor, and a line connecting the tips of the respective protrusions is defined as a conveying direction of the conveyor with respect to a horizontal line. And an adjusting mechanism for increasing or decreasing the angle of inclination of a line connecting the tips of the push-up projections is provided in the operating mechanism for the two scooping members.

[0007]

[Operation] In this configuration, when a plurality of rod-shaped substrates conveyed by the conveyor come into contact with the stopper and the conveyance is stopped, both scooping members are moved.
The operation mechanism moves upward from below. Then, each push-up projection on the upper surface of both scooping-up members pushes up each of the bar-shaped substrates, and each of the bar-shaped substrates is rotated, so that each of the bar-shaped substrates is vertically arranged from the horizontally arranged posture. Lifted off the conveyor while being rearranged at once. Then, in this state, the two scooping members are moved by the operation mechanism thereof to a position above the magazine and then moved down to below the magazine, whereby each of the rod-shaped substrates is vertically aligned. In this state, the magazines are fitted in the respective vertical grooves of the magazine, and are thus accommodated in the magazine in a vertically aligned posture.

[0008] Further, the line connecting the tips of the push-up protrusions is inclined obliquely upward with respect to the plane line in a direction opposite to the conveying direction of the conveyor. in, since will be pushed up in order from the rearmost rod-shaped substrate of the rod-like substrate, can sort the posture arranged vertically from posture arranged sideways, rod-like in the rearmost of the respective rod-like substrate The operations can be performed smoothly in order from the substrate, and the occurrence of errors can be reduced. Because each
Positioned in front of the rearmost rod-shaped substrate in the rod-shaped substrate
Other rod-shaped substrates that have
Is in contact with the rod-shaped substrate or stopper adjacent to
By pushing up the projection,
It is not easy to change the posture from the vertical to the posture,
Left and right longitudinal side surfaces of the rod-shaped substrate at the rearmost side
The rear longitudinal side is not in contact with anything.
From the horizontal position by pushing up the protrusion.
It is easy to change the orientation to the posture, and
Is performed for all the rod-shaped substrates.

By the way, since the width of each bar-shaped substrate varies, the length from the stopper to the rearmost side of the bar-shaped substrate at the rearmost side of the bar-shaped substrates on the upper surface of the conveyor is the same as that of the rod-shaped substrate. It will vary considerably due to variations in the width dimension of the substrate. Therefore, if the inclination angle of the line connecting the tips of the push-up protrusions in both scooping members is unchanged, the position of the stick-shaped substrate pushed up with respect to the rod-shaped substrate on the rear side is due to the variation in the width dimension of each rod-shaped substrate. Since each of the rod-shaped substrates is displaced in the width direction of the rod-shaped substrate from a position where the rod-shaped substrate is pushed up on the front side,
The rear-side bar-shaped substrate rotates in the opposite direction to the front-side bar-shaped substrate, in other words, turns upside down and is rearranged, and the rearrangement direction is not uniform.

[0010] In contrast, the present invention, as described above,
The operating mechanism for both scooping members is provided with adjusting means for increasing or decreasing the inclination angle of the line connecting the tips of the push-up projections. That is, when the inclination angle of the line connecting the tips of the push-up protrusions is increased, the contact point of each push-up protrusion with respect to each bar-shaped substrate moves so as to approach the stopper even when the inclination angle is small, so that the contact point from the stopper is increased. While the length dimension to the rear side of the rod-shaped substrate on the rearmost side of each rod-shaped substrate can be reduced due to the variation in the width dimension of each rod-shaped substrate, while the inclination angle is reduced, each push-up projection is By moving the contact point for each rod-shaped substrate away from the stopper than when the inclination angle is large, the length dimension from the stopper to the rear side of the rod-shaped substrate at the rearmost side of each rod-shaped substrate is Since it is possible to cope with the case where the length becomes longer due to the variation in the width of each rod-shaped substrate, And regardless of variations in the width dimension, it is possible to sort while rotating in the same direction.

[0011]

Thus, according to the present invention, the rearrangement of the rod-shaped substrates from the horizontal arrangement to the vertical arrangement can be performed simultaneously for a plurality of rod-shaped substrates. The work efficiency can be significantly improved, the cost required for the rearrangement can be significantly reduced, and the rearrangement can be automated.

Moreover, in the rearrangement, errors can be reliably prevented, and the rearrangement can be performed in the same direction irrespective of the variation in the width of each rod-shaped substrate.
