Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved method for simultaneously supplying and arranging a plurality of parts at a required pitch _p2 .

So-called batch processing involves arranging multiple identical parts at appropriate intervals and processing them simultaneously; for example, in the assembly of rectangular multi-pole connectors, a parallel group of many molded insulators are arranged in parallel so that they are in contact with their neighbors. A method of taking n insulators, arranging them at appropriate intervals, and simultaneously inserting one or more types of contacts into each insulator is widely used in mass-produced products.

In the conventional method of batch processing, as shown in _FIG .
A method of extracting and rearranging it to the required pitch p ₂ ,
As shown in Figure 2, the device or pitch _p2 ' is set in advance so that the required pitch _p2 ' is an integral multiple (in the figure, twice) of the adjacent parallel pitch _p1 , and only the corresponding insulator 1 is moved in a straight line. There is a method. However, since the insulator developed from pitch p ₁ to pitch p ₂ traces a relatively large curve, the device must be configured so that the presser for moving the insulator also moves in a curve. Therefore, there is a drawback that the configuration of the supplying device becomes complicated. On the other hand, in the latter method, the device or pitch _p2 ' is limited, so the supply device and the supplied parts processing device (contact insertion device) are limited.
However, it has the disadvantage of being unnecessarily large.

_{The present invention aims to eliminate the above-mentioned drawbacks, and its purpose is to take out a plurality of n parts from a parallel group of parts in which a large number of identical parts are arranged adjacently on a plane at pitch p 1 ,} and to As a method for supplying and arranging the required pitch p ₂ of an integral multiple, the n pieces taken out from the parallel component group are arranged so that the correspondence in the parallel direction is similar to the supply pitch p ₂ array from the parallel component group and is unequal. The selected parts including the parts lined up at intervals are selected, and the selected n parts are pushed by carriers disposed at corresponding positions and moved on the guide rails to be arranged at the pitch _p2 . This is achieved by a method of supplying and arranging multiple parts, which is characterized by:

Hereinafter, FIG. 3 is a plan view of the main parts of a device according to an embodiment of the present invention, FIG. , −′, − of the guide rail in Fig. 3
The present invention will be explained with reference to FIG.

3 and 4, the feeding and arranging device for molded insulators for rectangular multi-pole connectors includes a conveyor belt 2, guide rails 3, and a loading table 4 arranged in a plane, with a carrier running above the arrangement. 5 is configured to reciprocate in a straight line. Arrow B in Figure 3
The conveyor belt ₂ , which runs in the direction of ), and the most advanced insulator 1 _-1 of the parallel group hits the stopper 7 on the base 6 and becomes stationary. The guide rail 3 is a guide for rearranging a plurality of insulators (10 in the figure) set in advance to be selected from the parallel group of insulators to a required pitch p ₂ , and is a guide for rearranging a plurality of insulators (10 in the figure) to a required pitch p2, which will be described later. It has a groove 8 and a protrusion 9. And table 4
is the pitch of each insulator 1 that passed through the guide rail 3.
It is intended to be placed on p ₂ .

On the other hand, the timing belt 12, which is reciprocated via pulleys 10 and 11 provided approximately on the sides of the conveyor belt 2 and the load table 4, has an arrow C in FIG.
As shown, one end of a carrier 5 equipped with a plurality of claws 13 that can swing in a certain direction is attached, and the carrier 5 is attached to a pair of guide bars 16 and 17 attached to a base 6 via brackets 14 and 15. is guided by the belt 2, the guide rail 3, and the table 4 to reciprocate across the array. That is, the third
From the state where the carrier 5 is located outside the belt 2 (lower side in FIG. 3 and left side in FIG. 4) as shown in FIGS. When the carrier 5 is moved toward the table 4, the insulators 1 _{to 10} in the parallel group of insulators on the belt 2 are moved as shown in FIG.
Each claw 13 facing the insulator 1 pushes out the insulators 1 _{1 to 10} from the parallel group and passes them over the groove 8 of the guide rail 3, and the insulator 1 shown by the dashed line in FIGS. 3 and 4
_{-1 to 10} ', on the table 4 at the required pitch _p2 . However, the ten insulators 11 _{to 10} that are most similar to the required pitch _p2 are selected so that the guide rail groove 8 is as close to a straight line as possible. Therefore, insulators 1 _-1 , 1 _-2 , 1
_-5 , 1 _-6 , 1 _-9 , 1 _-10 , the adjacent insulators 1 are left on the belt 2, while insulators 1 _-3 and 1 _-4 ,
Two adjacent pieces of 1 _-7 and 1 _-8 are selected. Therefore, the guide rail 3 having a plurality of grooves 8, one of which faces the insulators 1-1 _{to 10} and the other of which faces the insulators _{1-1 to 10} ', requires a structure that separates the two adjacent grooves. .

Hereinafter, the separation configuration will be explained using FIG. 6 with reference to the above-mentioned figure. In order to clarify the relationship between the cross-sectional shape of the guide rail and the height of the conveyor belt 2 in FIG. 6, a line L indicating the upper surface level of the belt 2 is drawn on the side of each of the figures a to b. be.

In FIG. 6a showing the guide rail-' cross section, the guide rail 3 has eight protrusions 9 so as to form openings facing the insulators _{1-1 to 10} . Therefore, the insulators 1 _{-1 to 10} on the belt 2 pushed by the claws 13 are aligned in their original position and begin to enter the guide rail 3.

Next, in FIG. 6b showing the -' cross section of the guide rail 3, insulators 1 _-3 and 1 _-4 and 1 _-7 and 1
Since guide grooves 8 are formed between each protrusion ₉ except for the boundaries of insulators 1 _-1 , 1 _-2 , 1 _-5 , 1
_-6 , 1 _-9 and 1 _-10 immediately fall into each groove 8. However, insulators 1 _-3 and 1 _-4 and 1 _-7 and 1 _-8
First, only the lower part on the opposite side falls slightly into the groove 8, so after the upper part slopes away from each other as shown by the dotted line, each whole falls into the groove 8 by its own weight. As a result, the insulator 1 _{-1 ~ 10}
are inserted into ten different grooves 8.

Furthermore, in FIG. 6c showing the -' cross section of the guide rail 3, between the insulators 1 _-3 and 1 _-4 and between the insulators 1 _-7 and 1 _-8 , there are projecting upwards from slightly before the cross section. Fan-shaped protrusions 9' in plan view are respectively provided, and the intervals between the grooves 8 are approximately close to the required pitch _p2 .

The angle of inclination during the separation process of the adjacent insulators is determined by the dimensions of the insulators and their own weight, but if the angle is larger than necessary, the inclination will remain unfavorable. However, if the tilted position is maintained due to the above-mentioned excessive tilt, etc., each of them will fall into a predetermined groove 8 when abutted against the fan-shaped projection 9'.

In this way, the required pitch is achieved as shown in Figure 3.
While the insulators 1 _{-1 to 10} ' are being arranged and supplied at p ₂ , the conveyor belt 2 runs so that the gaps left by the insulators 1 _{-1 to 10} are filled with the remaining insulators 1. Then, when the timing belt 12 is driven in reverse and the carrier 5 moves back, the pawl 13 is flipped up in the opposite direction to the above-mentioned return by the group of adjacent parallel insulators newly formed on the belt 2. , and returns to the state shown in FIGS. 3 and 4. Thereafter, by reciprocating the carrier 5, ten insulators arranged at a pitch _p2 are supplied on the table 4 each time.

As explained above, according to the present invention, when supplying and arranging a plurality of parts at _the required pitch _p2 , the supply guide The rail groove is almost linear, which not only simplifies the configuration of the device, making it cheaper and more reliable in function, but also by changing the shape of the guide rail and the arrangement of the claws for pushing out the supplied parts, the required pitch p ₂ can be reduced. The practical effect is remarkable in that it has become easier to adapt to a plurality of types of parts to be supplied with different settings and shapes.
