Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is applicable to two cases: when assembling part A to part B at a constant pitch X, and when assembling part A to 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, when assembling a product 4 in which a part A3 is press-fitted into all of a plurality of holes 2 provided at equal intervals X in a part B1 as shown in FIG. 7, as shown in FIG. When assembling a product 7 in which the component A3 is integrally connected to the element body 5 at equal pitches X, and the component A3 is press-fitted into each hole of the component B1 as shown in FIG. 9, as shown in FIG. As shown in FIG. 8, it was necessary to form a member 8 in which parts A3 were integrally connected to the element body 5 at equal pitches Y (Y=2X), and to provide each part separately.

(Problems to be Solved by the Invention) As described above, if it is attempted to form the member 6 and the member 8 separately using the same device, it becomes necessary to change a part of the device, and when forming the member 8, the part A3 Since the pitch is large, there was a problem in that there was a lot of waste in terms of material collection and it became uneconomical. The present invention is intended to solve such problems, that is, to assemble a plurality of parts A to part B at a pitch of X by using only members in which parts A are integrally connected to the element body at a constant pitch of X. To provide a parts assembly device capable of freely assembling a product obtained by assembling a plurality of parts A to a part B with a pitch Y twice the pitch X using the same device.

(Means for Solving the Problems) The present invention includes a transport section A that transports a large number of parts A integrally connected to an element body at equal pitches X;
A conveying part B for transporting part A and part B to be assembled is provided oppositely, and a cutting part for cutting a predetermined number of parts A from the base body at every pitch Y that is twice the pitch X in the member, and the cut parts A. A station consisting of an assembly section for assembling parts B to part B is placed at a required position in transport part A, and when part A is separated at each pitch Y by the station at a required position in front of the station in transport part A, each pitch Y is From the cutting part where the element body in which part A remains is separated with the same number of parts A attached to the part A cut out at the above station, and the assembly part where part A of the cut element body is assembled to part B. On the other hand, the transport section B
A feeding unit that intermittently transports part B with a constant stroke so that it is positioned corresponding to the station, and a feeding unit that transports part B intermittently with a constant stroke so that it is positioned corresponding to the station are alternately operated. The above object is achieved by providing a parts assembly device which is arranged side by side and is characterized in that the station and the feed section can be stopped as appropriate so that only the station and the feed section can be operated.

(Example) An example will be described below based on FIGS. 1 to 5. First, the transport table (transport section A) 10 is placed on the base 9.
A conveyance rail (conveyance section B) 11 having a space between and
(See Figure 5). A member 6 is placed on the conveyor table 10, in which a large number of pin-shaped parts A3 with protruding top edges protruding from one side edge of a strip-shaped element 5 are integrally arranged at equal pitch X intervals ( (See FIG. 1 or FIG. 3) The member 6 is transferred intermittently with a constant stroke. A station 12 is arranged at a predetermined position on this conveyance table 10.
A station 13 is further arranged at a position a predetermined distance away from the station 2 in front. The station 12 is located above the root part of the component A3 in the member 6, and is arranged at every other pitch Y from the element body 5.
A multi-blade cutter (cutting section) 14 that cuts off a predetermined number of parts A3 for each (Y=2X), and a member 6
A pusher (assembly section) 15 that uses an air cylinder or the like to simultaneously press and move the plurality of parts A3 cut by the cutter 14 vertically and horizontally by a required stroke toward the conveyor rail 11, located on the side of the It consists of
Further, the station 13 includes a cutter (cutting part) 16 located above the element body 5 of the member 6 to cut off the element body 5 with the part A3 attached at a desired position, and a cutter (cutting part) 16 located on the side of the member 6. It consists of a pusher (assembly part) 17 that presses and moves the part A3 cut by the cutter 16 vertically and horizontally by a required stroke with the element body 5 still attached, toward the transport rail 11, and a station 12 and are configured to operate synchronously. Incidentally, when the part A3 is cut off by the station 12, the element body 5 to be cut by the cutter 16 has the same number of parts A3 as the cut parts A3.
It is cut at an appropriate position so that it has 3. Here, the cutter 16 and pusher 17 of the station 13 are always operated, and the station 1
The second cutter 14 and pusher 15 are configured so that they can be stopped as necessary. On the other hand, a carrier plate 18 is disposed at a lower position between the edges of the conveyor rail (conveyor section B) 11.
Feed pawls (feed portions) 19 are fixed to the feed pawls 8 at regular intervals, and feed pawls (feed portions) 20 are similarly mounted between the feed pawls 19 at regular intervals so as to be vertically movable. The carrier plate 18 makes one cycle of rectangular movement consisting of upward, forward, downward, and backward strokes, and the upward stroke causes the feed pawl 19 to move in a rectangular manner.
Then, the upper end of the feed claw 20 set in the raised position is projected from between the bottoms of the transport rails 11 to above the transport rails 11 and to the rear position of the part B1, and the part B1 is placed on the transport rails 11 by the forward movement. The part B1 is pushed forward, and the upper ends of the feed claws 19 and 20 are recessed into the space between the conveyance rails 11 by the downward stroke. Note that when the feed pawl 20 is set in the lowered position, even if the carrier plate 18 rises, the upper end of the feed pawl 20 does not touch the conveyor rail 1.
Does not stand out above 1. The carrier plate 18 is the conveyor table 10
The feed pawl 19 operates in synchronization with the component B1.
is positioned corresponding to the station 12 of the conveying section A, and the hole 2 and the cut part A3 are opposed to each other, and the feed claw 20 is positioned to correspond to the station 13, and the part B1 is positioned so that the hole 2 and the part A3 are opposed to each other. let

(Function) The function will be explained based on the drawings. First, FIGS. 1 and 2 show a state in which part A3 is assembled to part B1 at a Y pitch. In this case, the member to be transferred by the transport section A is not the member 8 in which the part A3 is provided for each pitch Y, but the member 6 in which the part A3 is provided in each pitch X. First, the member 6 is
is transferred at regular stroke intervals and transferred to station 1.
In step 2, a predetermined number of cutters 14 are used to cut every other part A3 from the base body 5 of the member 6, that is, each pitch Y, and the cut parts A3 are pushed by the pusher 15 to a predetermined position in the conveying section B. Hole 2 of part B1 stopped in position by feed claw 19
Press it into the The member 6 that has passed through the station 12 leaves parts A3 for each pitch Y on the element body 5. When the member 6 reaches the station 13, the cutter 16 cuts off the element 5 at a desired position, and the pusher 17 pushes the part A3 with the element 5 still attached to the transport section B at a predetermined position by the feed claw 20. The part B1 is then press-fitted into the hole 2 of the stopped part B1. That is, when assembling part A3 with part B1 at pitch Y, two products are assembled at the same time using station 12 and station 13. Next, FIGS. 3 and 4 show how part A3 is assembled to part B1 at pitch X. In this case, the member to be transported by the transport section A is, of course, the member 6 having the part A3 at the pitch X. In this case, the station 12 in the transport section A is stopped and the feeding section in the transport section B is also stopped. That is, the feed claw 19 is set in a lowered state. The component 6 transported by the transport section A is cut at a predetermined position of the element body 5 by the cutter 16 at the station 13, and is pushed by the pusher 17 and stopped at a predetermined position in the transport section B by the feed claw 20.
It is press-fitted into hole 2 of 1.

(Effects of the Invention) The structure and operation of the present invention are as described above. When part A is assembled to part B with pitch X, and when part A is assembled to part B with pitch Y which is twice the pitch X. In this case, only one type of member, which is made by integrally connecting parts A to a base body at pitches X, is sufficient, and there is no need to form a member having parts A for each pitch Y. This eliminates the hassle of having to change a part of the product, and also eliminates waste in terms of material collection. Furthermore, when part A is assembled to part B at pitch Y, the assembly can be done at the station and the station at the same time as described above, so there is an advantage that the assembly efficiency is doubled.
