FIGS. 5A to 5E show a member mounting section in an embodiment of the present invention, and this member mounting section is a part that guides the member A transferred from the member transfer section onto the jig of the processing device, and the member mounting structure 9
, a mounting structure support 8 that supports the member mounting structure 9 in a reciprocating manner, a mounting structure driving piece 7 that makes the member mounting structure 9 reciprocate once in the vertical direction in FIG. 5A, and this mounting structure driving piece 7. The transfer drive device 13, which is a drive source for the transfer drive device 13, etc.

(The connection structure between the transfer drive device 13 and the mounting structure drive piece 7 is shown in FIG. 2.

). 7. The main body 9a of the member mounting structure 9 is a hollow structure, and the hollow portion thereof forms a member transfer path 9b.

This member transfer path 9b forms a prismatic space according to the transfer state of member A, for example, as shown in the fifth diagram, and its dimensions AI and A2 are the lengths across the length of the protrusion C portion of member A. The width T2 and the width W are set to be approximately equal within a range not shorter than that, and the member A carried into the member mounting structure 9 falls in the member transfer path 9b as shown by the two-dot chain line in FIG. .

Above the member mounting structure 9 in FIG. 5A, a member loading port 9d is formed by removing a portion of the wall forming the member transfer path 9b, and further above the member loading port 9d. A part of the wall behind the loading entrance 9d is removed,
A drive roller 9e is rotatably provided at that portion.

Further, a spring locking rod 9C is attached below this member mounting structure 9.

A mounting structure support groove 8b into which the member mounting structure 9 is slidably fitted is formed in the main body 8a of the mounting structure support 8, and the member mounting structure 9 is fitted and mounted in the mounting structure support groove 8b. After that, by attaching the closing plate 8e, the member mounting structure 9 is supported by the mounting structure support 8 so as to be slidable in the vertical direction in FIG. 5A.

Note that this is the member loading port for the closing plate 8e. A portion corresponding to 9d is formed into an opening shape in accordance with the shape of the member delivery end 5d of the main body 5a of the member transfer structure 5, and forms a transfer structure fitting portion 8d.

Further, a spring locking rod 8C is fixedly attached to the main body 8a of the mounting structure support 8, and the main body 9 of the component mounting tank integrated 9 is attached to the spring locking rod 8C.
A 10-force spring I is attached between a spring locking rod 9C580 fixed to both the main body 8a of the mounting structure support 8 and the spring locking rod 9C580.

The spring 10 causes the driving roller 9e of the member mounting structure 9 to come into contact with the mounting structure drive piece 7.

' is always oriented upwardly in FIG. 5A with respect to the mounting structure support 8.

The mounting structure driving piece 7 is a driving roller 9e of the member mounting structure 9.
The contact side 7a with the drive roller 9e is disposed above the member mounting structure 9 in contact with the drive roller 9e.

A sloped side 7b is formed on the side, and a step having a height Hl is formed between the sloped side 7b.

The mounting structure driving piece 7 formed as described above moves in the left-right direction in FIG. 5A by the operation of the transfer drive device 13, and its inclined side 7b moves the member/mounting structure 9 in the vertical direction in FIG. 5A. move it.

That is, in FIG. 5A, when the mounting structure drive piece 7 moves rightward, the drive roller 9e moves downward following the abutting side 7a, and the member mounting structure 9 moves along the inclined side 7.
It moves downward in FIG. 5A by a distance equal to the height Hl of the step formed by b.

In addition to the above-mentioned drive mechanism for the member mounting structure 9, the member mounting structure 9 may also be driven by a mechanism that uses an eccentric cam, a mechanism that uses the tensile force of a plunger, etc. As will be described later, when the member A is mounted in the member mounting hole 16C of the processing jig 16, the material discharge port 9f is configured to approach the member mounting hole 16C. Bye.

The transfer drive device 13 is constituted by a drive means such as an air cylinder, for example, and is fixed to the member aligning and supplying device by a drive device fixing body 14, and the drive shaft 13b is telescopically operated.

As shown in FIG. 2, a connecting body 12 is fixed to the tip of this drive shaft 13b, and the above-mentioned member transfer piece 6 and a mounting structure driving piece 7 are connected to this connecting body 12 via a connecting rod 11.
is fixed, and the member transfer piece 6 and mounting structure drive piece 7 simultaneously move in the left-right direction in FIG. 2 by the expansion and contraction operation of the drive shaft 13b.

As shown in FIG. 2, a plurality of processing jigs 16 are provided on the processing table 15, each of which includes a main body 16a having a member mounting hole 16C, and a member (core) inserted into the member mounting hole 16C by the member aligning and supplying device. ) After A is supplied, the part (
A member guide body 16b is configured to correctly guide the member (yoke) B onto the processing jig 16 when placing the member (yoke) B thereon.

Further, the processing table 15 has, for example, a rotary table mechanism, and when the member (core) A is mounted on the processing jig 16, the processing table 15 rotates, and the processing table 15 rotates when the member (core) A is not mounted on the processing jig 16. The tool 16 is configured to move below the member mounting structure 9.

However, in FIG. 2, the rotary table mechanism is rewritten as a mechanism that moves linearly to the left, and in this case, one movement of the processing table 15 is performed by moving the adjacent processing jig 16, It can be considered by replacing the movement with a movement to the left by a length equal to the installation distance between 16 and 16.

The parts described above are arranged as shown in FIG.

That is, the member alignment structure 1 is inclined so as to descend in the direction of transport of the member A, and is set so that its member delivery end 1f is in contact with the diagonally upper part of the member guide body 5C of the member transfer structure 5.

In addition, the member transfer path 1b of the member alignment structure 1 and the member transfer structure 5
The member transfer path 5b of the member transfer structure 5 is set to be in a straight line when viewed from above in FIG.
The height H2 to the upper end is set to 2 or less, which is the length from the end of the member A where the protrusion C is not provided to the protrusion C.

The member delivery end 5d of the member transfer structure 5 is fitted into a transfer structure fitting portion 8d provided on the mounting structure support 8.

In this state, the member transfer path 5b of the member transfer structure 5 comes into contact with the member loading port 9d of the member mounting structure 9.

In addition, the operation of the processing table 16 is controlled by the member mounting hole 1 of the processing jig 16.
6C is controlled so that it is located directly below the member transfer path 9b of the member mounting structure 9.

Before the mounting operation of the member A on the processing jig 16, the member ejection port 9f of the member mounting structure 9 is located above the upper end of the member guide body 16b of the processing jig 16, and the member A is processed in the processing jig 16. During the mounting operation on the jig 16, the member mounting structure 9 is lowered by Hl as described above, and the member outlet 9f approaches the member mounting hole 16C of the processing jig 16.

Further, as described above, the member transfer piece 6 and the mounting structure drive piece 7 are simultaneously moved by the operation of the transfer drive device 13.

Therefore, the transfer of the member A on the member transfer structure 5 and the lowering of the member mounting structure 9 are performed simultaneously.

Furthermore, when the mounting structure drive piece 7 is not operating, the distance S2 from the point where its contact side 7a contacts the drive roller 9e to the point where the inclined side 7b ends is the moving distance Sl of the member transfer piece 6 ( This moving distance S1 is equal to the moving distance of the mounting structure driving piece 7.

) is set shorter. Therefore, the member transfer piece 6 moves the distance S1 and pushes the member A to the right in FIG. The member mounting structure 9 has already descended by the height Hl, and the member ejection port 9f at the lower end has approached above the member mounting hole 16C of the processing jig 16.

In the embodiment, as described above, the member alignment structure 1 was set in an inclined shape that descends in the direction of transport of the members, but this is because the transport of the member A is performed by natural sliding down due to the gravity acting on the member A. For example, if a transfer means that utilizes the repulsive force of a spring or compressed air is provided, the member alignment structure 1 does not necessarily have to be set in an inclined shape.

(Operation of the embodiment of the present invention) Next, the operation of the member alignment and supply device of the embodiment configured as described above will be described.

a. Aligning operation of members First, the aligning operation of members A will be explained with reference to FIGS. 6A to 6K.

In FIGS. 6A to 6K, in order to identify each member A, a hyphen "-" is added to the symbol "A" indicating the member, such as 'A 9J', and an identification symbol (number) is written.

The state shown in FIG. 6A is that of the member supply device (not shown).

) are supplied to the member alignment structure 1 in an overturned state, and the members A-12, A-13, A-14... are transferred to the member alignment structure 1 by the member stop protrusion 2b of the member feeding structure 2. It shows the state where it is kept on the road 1b.

In addition, in this state, the transfer drive device 13 is activated, the drive shaft 13b is extended, the member transfer piece 6 moves to the right in the drawing in the member transfer path 5b of the member transfer structure 5, and the member transfer structure 5 has already been moved to the right in the drawing. Members A-11, A-10 sent out onto 5,
A-9... is in a state where it is pushed out to the right and transferred on the member transfer structure 5.

Also, members A-12, A-13, A-14...
is the member transfer path 1 of the structure 1 whose overturning direction is disorderly aligned.
b.

In this case, member A-12. A-15 etc. are members A-13 and A-1 in such a position that the protrusion C is at the rear end in the transport direction.
It is assumed that the fourth grade is supplied with the protruding strip C at the front end in the transport direction.

When the members A-11, A-10, A-9, . When the member transfer piece 6 makes one reciprocation in the member transfer path 5b of the member transfer structure 5, the members A-11, A-10, A-9, etc. are moved to the right in the drawing by the width W of the member A. will be transferred to

) The drive shaft 13b of the transfer drive device 13 is pulled into the drive body 13a, and as shown in FIG. 3 operates, and its rotating shaft 3b
rotates to the left, and the member feeding structure 2 operates in the direction of the arrow.

When the member feeding structure 2 operates in the direction of the arrow, the member A-1
The member retaining protrusion 2b that was restraining the member A-12 is removed from the member A-12, and the member pushing protrusion 2C presses the member A-13 into the member transfer path 1b of the member alignment structure 1. to lock.

Therefore, only the member A-12 slides down the member transfer path 1b set in an inclined manner in the convex direction of the arrow.

Since the member A-12 is being transported in such a state that the protrusion C is at the rear end in the transport direction, the member A-12 moves in the convex direction of the arrow in the member transport path 1b, and the member alignment gap 1C is When reaching the formed portion, as shown in FIG.
, and the member A-12 rotates in the two directions of the arrows.

As mentioned above, the width W2 of the member alignment gap 1C is set to be approximately equal to the thickness T1 of the member A, forming a stepped portion 1e between it and the member transfer path 1b, and forming a stepped portion 1e on both sides of the member A. Since the length T2 between the vertices of the protrusions C is longer than the width W2 of the member alignment gap 1C, the member A-12 is located in the member alignment gap 1.
When proceeding to the place where the protrusion C is formed, the protrusion C gets caught on the stepped part 1e, as shown in the sixth diagram, and further rotates in two directions around the protrusion C, changing its shape. Proceed further in the convex direction while aligning the protrusion C in the upward direction.

As described above, the member discharging end 1f of the member alignment structure 1
and the height H of the member transfer structure 5 to the upper end of the member transfer path 5b.
2 is shorter than the dimension L2 of member A, so just before the member A-12 reaches the member delivery end 1f, its lower end enters the space of the member transfer path 5b of the member transfer structure 5. .

When the member A-12 further advances in the convex direction and is discharged from the member discharging end 1f of the member alignment structure 1, the member A-12 moves along the member transfer path of the member transfer structure 5 as shown by the arrow H in FIG. 6E. 5b.

As described above, the tip of the member A-12 has already entered the member transfer path 5b of the member transfer structure 5 before the member A-12 is discharged from the member delivery end 1f of the member alignment structure 1. The member A-12 is correctly guided from the member alignment structure 1 to the member transfer structure 5, and as described above, the width W3 of the member transfer path 5b of the member transfer structure 5 is equal to the thickness T of the member A.
1, so that as shown in FIG. The member transfer path 5 is caught on the upper end and suspended.
It is placed in b.

In addition, the member guide body 5C does not move the member A-12 in the above operation.
When being transferred to the member transfer structure 5, the member A-12 is prevented from deviating from the member transfer path 5b due to vibration or the like.

Further, until the above operations are completed, the member feeding structure 2 continues to operate in the direction of the arrow (see FIG. 6B), and the member A
Since the member A-13 is continuously pressed and locked into the member transfer path 1b of the member alignment structure 1 by the member pushing projection 2C, the member A-
13 and members A-14, A-15, . . . are retained in the member transfer path 1b.

When the member A-12 is transferred onto the member transfer structure 5 as described above, the transfer drive device 13 is activated and the drive shaft 1
3b expands and the member transfer piece 6 moves in the direction of the arrow as shown in FIG. 11
The members A-11, A-10, A-9,...
・move to the right in the drawing by the width W of member A, respectively.

By this operation, the member A-1 (see FIG. 7A) placed on the rightmost end of the member transfer structure 5 is transferred to the member loading section, but this operation will be explained later in FIGS. 7A-D. This is explained by

Also, at the same time as the member transfer piece 6 moves in the direction of the arrow,
Alternatively, the feed structure drive device 3 operates back and forth, its drive shaft 3b rotates to the right, and the member 1 feed structure 2 operates in the direction of arrow 1, which is the opposite direction to that shown in FIG. 6B.

When the member feeding structure 2 operates in the direction of the arrow H, the member pushing protrusion 2
The pressing force on the member A-13, which had been pressed and locked by the member A-13, is removed, and the member locking protrusion 2b projects into the member transfer path 1b of the member alignment structure 2, and the member A-1
3 moves in the direction of the arrow until it is stopped by the member stop protrusion 2b, and the members A-14, A-15, A-16...
. . . also move in the direction indicated by the arrow by the same distance as the member A-13.

When the above operations are completed, the member transfer piece 6 is moved as shown in FIG. 6G.
moves again in the direction of arrow A, and at the same time or before or after that, the member feeding structure 2 rotates again in the direction of the arrow, and the member A-13 is moved in the same manner as in the above-described operation in FIG. 6B. As the restraint by the stop projection 2b is released, the member A-14 is pressed into the member transfer path 1b of the member alignment structure 1 by the member pushing projection 2C, and the following members A-15, A-16, etc. - is also retained in the member transfer path 1b.

When the member A-13 is released from being restrained by the member stop projection 2b, it slides down the member transfer path 1b of the member alignment structure 1 in the convex direction of the arrow.

In this way, the member A is sent out into the member transfer path 1b intermittently every time the member feeding structure 2 rolls in the direction of the arrow.

The member A-13 is carried into the member alignment structure 1 in a direction opposite to the transport state of the member A-12 described above.

That is, the member A-13 is moved along the member transfer path 1b of the member alignment structure 1 in such a manner that the protrusion C is at the front end in the transfer direction.
Move inside in the direction of the convex arrow.

When the front end in the transport direction reaches the member alignment gap 1c, it becomes as shown in FIG. The protrusion C of the member A-13 is caught on the stepped portions 1e formed on both sides of the member alignment gap 1C, and the member A-
13 moves in the convex direction of the arrow while maintaining substantially its previous position until its rear end in the transport direction reaches the member alignment gap 1c.

When the rear end of the member A-13 in the transport direction reaches the member alignment gap 1C, as shown in FIG. While rotating in the direction of the arrow H, the part where the member alignment gap 1C is provided is slid down in the convex direction of the arrow. In other words, the member alignment gap 1 is caused by the difference in the transport posture of the member being transferred through the member alignment structure 1.
The direction of rotation received at the part where C is provided is reversed, but in this case as well, as shown in Fig. 6 C and D,
The member A-13 is arranged in a direction with the protruding strip C facing upward.

As shown in FIG. 6J, as in the case of the sixth plan, the member A-13 is at the member delivery end 1f of the member alignment structure 1.
Immediately before reaching the point, the lower end enters the space of the member transfer path 5b of the member transfer structure 5 and moves in the convex direction of the arrow, and when the member is finally discharged from the member delivery end 1f, as shown in FIG. 6K. The member A-13 is transferred in the direction of the small arrow,
The member transfer structure 5 is placed in the member transfer path 5b in a suspended state with the protrusion C force bows 1 hanging on the upper ends of both side walls of the member transfer path 5b.

After this operation, the same operations as explained in FIGS. 6F and 6G are repeated, and the members A arranged in a certain posture on the member transfer structure 5 are sequentially delivered to the member mounting section. Ru.

As described above, when the member A is transferred through the member transfer path 1b of the member alignment structure 1 with the protruding strip C of the member A being at the rear end in the transfer direction in the member alignment section, FIGS. Contrary to the above, when the protrusion C of the member A is transferred in a position such that it is at the front end in the transport direction, the member A is moved by the action shown in FIG. The members are arranged in a direction in which the protruding stripes C are directed upward and are transferred to the member transfer structure 5.

b. Operation of supplying the member to the processing jig Next, FIGS. 7A to 7D show the operation when supplying the member A sent to the member alignment structure 5 by the above operation onto the jig of the welding device 1, for example. explain.

In FIGS. 7A to 7D, the symbols for member A are shown according to the same rules as shown in FIGS. In order to
is written.

FIG. 7A shows a state in which the member A-12 has been transferred and placed on the member transfer structure 5 through the operations shown in FIG. 6E or 6K.

On the processing table 15 shown in FIG. 7A, processing jig] 6-1
The member mounting hole 16C is opened by the operation described below.
The member (core) A-0 has already been attached 1 to the member (core) A-0, and the member (yoke) B is further attached to the member (core) B according to the guide of the member guide body 16b.
Core) A-0 is placed on top of the processing jig 16.
The processing jig 16-2 adjacent to -1 is located directly below the member loading port 9f of the member mounting structure 9.

Note that the operation of placing the member (yoke) B onto the processing jig 16 is not directly related to the present invention and will not be mentioned in the description of this embodiment.

When the transfer drive device 13 is activated and its drive shaft 13b is extended, the member transfer piece 6 moves in the direction of the arrow as shown in FIG. It is transferred in the direction of arrow G while being suspended in the transfer path 5b.

Simultaneously with the movement of the member transfer piece 6 in the direction indicated by the arrow, the mounting structure drive piece 7 moves in the direction indicated by the arrow, and the member is moved in accordance with the movement of the contact side 7a in contact with the drive roller 9e. The mounting structure 9 descends in the direction of arrow N.

That is, when the mounting structure drive piece 7 moves in the direction of the arrow and the drive roller 9e approaches the inclined side 7b of the contact side 7a, the member mounting structure 9 starts to descend in the direction of the arrow N. When the mounting structure drive piece 7 moves by the distance S2 (in the mounting structure drive piece 7 of FIG. 7B, the distance S
The position of the inclined side 7b when moved by 2 is shown by a dotted line.

) The member mounting structure 9 descends against the elastic force of the spring 10 by a distance equal to the height Hl of the step formed by the inclined side 7b, and the member unloading end 9f reaches the processing jig 1.
6-2 approaches the member mounting hole 16C.

At this point, the member transfer piece 6 is still moving the distance S1.
Since the member A-1 has not been moved yet, the member A-1 has not been carried into the member transfer path 9b of the member mounting structure 9.

When the member transfer piece 6 further moves in the direction of the arrow, the member A-
12 is further transferred in the direction of arrow T, and eventually comes into contact with member A-11 as shown in FIG.
is pushed in the direction of the small arrow, and these members A-11 to A-1 are transferred by approximately the width W of the member A in the direction of the small arrow.

As a result, the member A-1 is transferred to the member transfer path 5 of the member transfer structure 5.
A is pushed out to the member loading port 9d of the member mounting structure 9, falls in the direction of arrow O, and falls down the member transfer path 9b of the member mounting structure 9 as shown by the two-dot chain line to form the processing jig 16-2. It is mounted in the mounting hole 16C.

At this time, since the member discharging end 9f of the member mounting structure 9 is close to the member mounting hole 16C, the member A-1 is securely inserted into the member mounting hole 16C.

When the above operations are completed, the transfer drive device 13 is activated and its drive shaft 13b is drawn into the drive body 13a, and as shown in the seventh diagram, the member transfer piece 6 moves in the direction of arrow A, and the mounting structure drive piece 7 moves in the direction of arrow A. The members move in the directions of the arrows W, and the member transfer path 5b near the member guide body 5C of the member transfer structure 5 becomes empty (the member A and the member transfer piece 6 are not present), and the restoring force of the spring 10 causes the member to move. The mounting structure 9 raises the step height Hl of the inclined side 7b in the direction of the arrow force, and returns to its original state (the state shown in FIG. 7A).

When the component mounting structure 9 finishes rising in the direction of the arrow force, the processing table 15
operates in the direction of the arrow Y, and moves the processing jig 16-3 on which the member A is not yet mounted to the member unloading end 9 of the member mounting structure 9.
Move it directly below f and stop.

When the processing table 15 is operated, the member carrying-out end 9f of the member mounting structure 9 is away from the processing jig 16, so the above-mentioned processing can be carried out without any inconvenience such as the member mounting structure 9 hanging on the member guide 16b. The stand 15 can be moved in the direction of the arrow y.

Further, when the processing jig 16-2 on which the member A-1 has been mounted comes to the position shown in Fig. 7 by the movement of the processing table 15 in the yaw direction, the member B is mounted according to the member guide 16b, and further at this time. , a processing jig 16 preceding the processing jig 16-2.
-1 has come to the position shown in Figure 7 by the operation of the processing table 15, and here processing is performed, such as fixing member A-0 and member B to each other by spot welding, for example.

Simultaneously with the operation of the transfer drive device 13, or before or after, the feed structure drive device 3 operates, and the movement described in FIG.
The member A-13 is supplied to the machine member A-13, and the member A-2 is again supplied to the processing jig 16-3 by the above-described operation, and the above-described operation is repeated thereafter.

(Effects of the Invention) As is clear from the above detailed description using examples, the present invention has various unique effects as listed below.

(A) Since the member A is arranged in a substantially upright position in advance in the member alignment structure 1 in which the member alignment gap 1C is formed in the member alignment section, and then the member A is sent to the member transfer section, the member A is kept correctly and uniformly. , and are reliably transported and supplied to the processing equipment without deviating from the equipment.

That is, when the member alignment gap 1C is not provided in the member alignment structure 1 and the member A is simply used as a member transfer path from the member supply device, the member A rotates about the protrusion C as a fulcrum in the member transfer structure 5, and its posture is changed to an upright position. However, in this case, since the member A is transferred to the member transfer structure 1 while being overturned, it is difficult to reliably guide the member A to the member transfer path 5b (especially when the protrusion C In the case where the side is the leading edge in the transport direction), this problem is cleverly solved in the present invention by providing a member alignment gap 1C.

(B) Generally, the processing jig 16 is provided with a structure such as a member guide body 16b near the member mounting hole 16C. It became necessary to provide a gap between the member carrying-out port 9f of the structure 9 and the member mounting hole 16, and as a result, it was difficult to reliably mount the member A into the member mounting hole 16C.However, in the present invention, Processing jig 16 for component A
The above-mentioned problem is solved by bringing the member outlet 9f close to the member mounting hole 9f of the processing jig 16 only when mounting the processing jig 16 on the processing jig 16.

That is, according to the present invention, the member A can be reliably supplied to a predetermined position of the processing device without any hindrance to the operation of the processing device.

(C)-According to the present invention, even if the members A are continuously and disorderly supplied from the member supply device to the member alignment structure 1, the parts A are intermittently supplied each time the processing device (processing table 15) is operated due to the operation of the member feed structure 2. Since it is possible to supply the above-mentioned member A and automatically adjust its appearance, it is possible to automate processing steps such as spot welding of the core and yoke of an electromagnetic relay, for example.
