Abstract

PURPOSE:To enable parts to be incorporated in equal pitch and double pitches by disposing a station I in which a series of parts in equal pitch are separated in every double pitches for incorporation and a station II in front of said station in which remaining members in every double pitches are separated for incorporation to stop freely the station I. CONSTITUTION:Members I6 are transferred at every fixed stroke and cut off from a blank 5 at every other member in a station I12 by a predetermined number of cutters I14 and forced into a hole of a part B1 a pusher I15. When the member I6 reaches a station II13, the blank 5 is cut off by a cutter II16 to be forced into the hole of the part B1 by a pusher II17. When a part A3 is thus assembled in a part B1 with double speed, the stations I, II, 12, 13 are utilized to assemble two products at the same time, and in the assemblage with equal pitch the station I12 and a feeding section I are stopped. The blank 5 is cut off by the cutter II16 in the station II13 to be forced into the hole of part B1 by a pusher II17.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is applicable to two cases: when a part A is assembled to a part B at a constant pitch X, and when a part A is assembled to a part B at a pitch Y that is twice the pitch X. This invention relates to a parts assembly device that can be used together.

(Prior art) Conventionally, for example, as shown in Fig. M7, a product (4) is assembled in which part A (3) is press-fitted into all of the plurality of holes (2) provided at equal intervals X in part B (11). In this case, as shown in FIG. 6, parts A (3) are integrally connected to the element body (5) at equal pitches X to form a member I (61'), and as shown in FIG. (When assembling the product (7) in which parts A (3) are press-fitted at intervals of 11, as shown in Figure 8, the parts A It was necessary to form a member (8) in which (3) was integrally connected and to provide each member separately.

(Problems to be Solved by the Invention) If an attempt is made to separately form member I (6) and member ■(8) using the same device as described above, it will be necessary to change a part of the device, and member 8), part A (3
) Since the pitch is large, there is a problem in that there is a lot of waste in terms of material removal and it becomes uneconomical. The present invention solves this problem, that is, by using only the member I, in which the parts A are integrally connected to the element body at a constant pitch X, a plurality of parts A are connected to the part B at a pitch X. The purpose of the present invention is to provide a parts assembly device that can freely assemble assembled product ■ and product II, in which multiple parts A are assembled to part B at a pitch Y that is twice the pitch X, using the same equipment. shall be.

(Means for Solving the Problems) The present invention consists of a transport section A that transports a member (■) in which a large number of parts A are integrally connected to an element body at equal pitches X, and a transport section A that transports a part B to be assembled with one part A. In section II, a cutting section ■ separates a predetermined number of parts A from the element body at intervals of pitch Y, which is twice the pitch Station I consisting of the assembly section ■ to be assembled is placed at the required position to the transport section, and l! When the parts A of each pitch Y are cut out at the required position in front of station ■ in the feeding section A, the parts A of each pitch Y will remain in the same number of parts A as the parts A cut out at the above station ■. A station II is provided, consisting of a cutting section II that separates the part A with it attached, and an assembly section II that assembles the cut element A to the part B. On the other hand, in the transport section B, the part B is transferred to the station ■. The feeding section ■, which transfers part B intermittently with a partial stroke so that it is located in a corresponding position, and the feeding section II, which transfers part B intermittently with a partial stroke so that it is located in a corresponding position with station II, are arranged alternately. The purpose of the present invention is to achieve the above object by providing a parts assembling device which is characterized in that the station I and the feed section (2) can be stopped as appropriate so that only the station II and the feed section II can be operated. be.

The member (6) transferred by the conveyance section A is cut at the required position of the element body (5) by the cutter ■αe at the station ■a3, and is pushed by the button shear II (171) to a predetermined position on the conveyance section B. It is press-fitted into the hole (2) of part B (1) which has been stopped by the feed claw ■■.

(Effects of the Invention) The structure and operation of the present invention are as described above, including the case where part A is assembled to part B at pitch X, and the case where part A is assembled to part B at pitch Y, which is twice pitch X. In this case, the only member to be used is one type of member (■) consisting of parts A integrally connected to the base body at pitch X, and there is no need to form member II having parts A at each pitch Y, so member (■) is used. This eliminates the hassle of changing a part of the manufacturing equipment, and also eliminates waste in terms of material collection. Furthermore, when part A is assembled to part B at pitch Y, it can be assembled at station 2 and station II at the same time as described above, so there is an advantage that the assembly efficiency is doubled.
