The present invention relates to an automatic parts supply device that can quickly and reliably feed valve guides to a press-fitting device while separating valve guides at desired intervals.

[Prior Art] Engines constituting internal combustion engines are assembled quickly and efficiently in factories using automated line production processes. For example, in the work of assembling valve guides into a cylinder head in order to mount an inlet valve or an outlet valve to the cylinder head, the valve guides that are conveyed via a parts feeder, etc. are fed into a predetermined number by an automatic supply device. This is done automatically by placing the valve guides at desired intervals and feeding them into a press-fitting device, and then press-fitting the valve guide into the cylinder head via the press-fitting device.

The work of feeding a and 26b will be explained.

First, the process of conveying the valve guides 26a, 26b to the automatic supply device 10 by the parts distribution device 16 will be described in detail.

A large number of valve guides 26a and 26b are supplied to the parts feeders 22a and 22b, respectively.
The arrangement mechanism 30 is operated via the tubular bodies 28a and 28b under the driving action of the parts feeders 22a and 22b.

This results in it being located on the same line as 3.

Next, when the cylinder rod 44 is displaced in the direction of arrow A under the driving action of the cylinder 42, the distribution member 46 attached to the cylinder rod 44 is moved.
is guided by guide bars 54a and 54b and displaced in the direction of arrow A while holding eight valve guides 26a. For this reason, first, the eighth valve guide 26a located at the highest position is connected to the distribution plate 5.
6, falls from the opening 60a toward the plate 36, and enters the groove 38a formed in the plate 36. Since the plate body 36 is oriented in the vertical direction and is inclined, the groove portion 38a
The valve guide 26a that has fallen down slides and enters the tubular body 40a that communicates with the groove portion 38a.
Furthermore, when the distribution member 46 is displaced in the direction of arrow A, the next valve guide 26a (seventh) falls from the opening 60b into the groove 38b of the plate 36, and slides along the slope of the groove 38b. and reaches the tubular body 40b.

As described above, as the distribution member 46 is displaced in the direction of arrow A, the valve guide 26a housed in the fitting groove 48 is sequentially moved through the openings 60a to 60h of the distribution plate 56 to the groove 38a of the plate body 36.

The holes 114a to 114h of the chuck pocket 98a facing the chuck pocket 78 fall into the holes 114a to 114h. At this time, as shown in FIGS. 6 and 7, the roller 139 supported on one end of the cam member 130
46a, the cam member 130 is displaced upward against the elastic force of the coil spring 140, and its outer peripheral surface is engaged with the lock pins 120a to 120a.

A chuck pocket 98a fixed to the mounting portion 112a of the press-fitting device 68 faces the press-fitting device 68. At this time, when the chuck pocket 98a rotates in the direction of the arrow via the arm member 108a, the roller 139 of the cam member 130 provided on the chuck pocket 98a is displaced along the cam surface 146a and separated from the fixed cam member 144a. As a result, the cam member 130 is connected to the coil spring 14.
The flange portion 13 descends through an elastic force of 0.
4 is placed in contact with the chuck pocket 98a. Therefore, the groove 13 of the cam member 130
6a to 136h communicate with the holes 118a to 118h, and the lock pins 120a to 120h inserted into the holes 118a to 118h have their distal ends connected to the grooves 136a to 118h through the elastic force of the coil springs 126a to 126h. 136
Enter h. As a result, the circumferential grooves 124a to 124 formed in the lock pins 120a to 120h
h engages with each valve guide 26a, and the valve guides 26a are fixed in the holes 114a to 114h via the locking pins 120a to 120h.

Furthermore, when the rack 102 is displaced in the direction of arrow B under the driving action of the cylinder 100 and rotated about the rotating shaft 96a, the roller 139 supported by the cam member 130 is moved against the cam surface 144 of the fixed cam member 144b.
b. Therefore, the cam member 130 rises against the elastic force of the coil spring 140, and the inclined surface portions 138a to 138h defining the grooves 136a to 136h of the cam member 130 lock the lock pins 120a to 120h into the holes 118a to 11.
Press within 8h. As a result, the lock pin 1
20a to 120h circumferential grooves 124a to 124h
The valve guides 26a are loosely fitted into each valve guide 26a, and the fixing action of the valve guides 26a is released.

As described above, as the rotating shaft 96b rotates under the driving action of the cylinder 100, the arm member 108b attached to the rotating shaft 96b rotates.
The chuck pocket 98b is connected to the press-fitting device 68 through the
Face to side.

Next, as shown in FIG.
2, move the cylinder rod 92a in the direction of arrow C.
When the movable main body 84 is displaced in the direction, the movable main body 84 engaged therewith is guided by the guide bars 94a and 94b and is displaced in the direction of the arrow C with respect to the movable base 88. Therefore,
The respective chuck pockets 98a and 98b are displaced integrally with the movable main body 84 in the direction of arrow C, and the valve guides 26a arranged and housed in the chuck pocket 98a are delivered to the attachments 68a to 68h of the press-fitting device 68.

Therefore, under the driving action of the second cylinder 92, the cylinder rod 92a is displaced in the direction opposite to the arrow C to separate the movable main body 84 from the press-fitting device 68, and then the first cylinder 86 is driven. Therefore, the cylinder rod 86a is displaced in the direction of arrow D, and the movable base 88 is moved in the direction of arrow D together with the movable main body 84. At this time, the press-fitting device 68 rotates so that the press-fitting attachments 68i to 68p of the press-fitting device 68 face the chuck pocket 98b. Further, as described above, under the action of the second cylinder 92, the valve guide 26b held in the chuck pocket 98b is inserted into the press-fit attachment 68.
After feeding from i to 68i, the movable main body 84 is separated from the press-fitting device 68.

In this way, each of the chuck pockets 98a,
Valve guide 26a from 98b to press-fitting device 68,
26b, when the cylinder 100 is driven to displace the rack 102 in the direction opposite to the arrow b, the pinion 104 meshes with the rack 102.
rotates in a direction opposite to the arrow, and furthermore, a rotating shaft 96b on which this pinion 104 is provided and a rotating shaft 9 that engages with this via respective gears 106a and 106b.
6a rotates in the opposite direction to the arrow. Therefore,
An arm member 108 is attached to each rotating shaft 96a, 96b.
The chuck pockets 98a and 98b, which are engaged via the lower positioning plates 7a and 108b,
8, and the valve guides 26a, 26b are on standby to receive the valve guides 26a, 26b conveyed via the arrangement mechanisms 30a, 30b.

On the other hand, the press-fitting device 68 is connected to the desired valve guide 26.
After receiving the valve guides a and 26b, the valve guide 2
6a and 26b are press-fitted into a cylinder head (not shown).

As described above, the work of sending out the valve guides 26a and 26b conveyed via the arrangement mechanisms 30a and 30b forming the parts distribution device 16 to the press-fitting device 68 via the first parts feeding mechanism 69a forming the automatic supply device 10 concerned However, it is easily understood that the operation of feeding the valve guide to the press-fitting device (not shown) via the other arrangement mechanisms 32a, 32b and the second parts feeding mechanism 69b is performed in the same manner as described above.

In this case, according to this embodiment, for example, the valve guide 26a sent out via the parts distribution device 16 can be reliably fed to the press-fitting attachments 68a to 68h of the press-fitting device 68, and various It becomes possible to easily correspond to different press-fitting devices. That is, as described above, the arrangement mechanism 30 that constitutes the parts distribution device 16
The valve guides 26a are always spaced apart at equal intervals and sent out in desired numbers to the upper positioning plate 74 constituting the automatic supply device 10. For this reason, it is sent out to the upper positioning plate 74. Therefore, the parts insertion holes 76a to 76j of the upper positioning plate 74 are connected to the tubular bodies 40a to 40 fixed to the support member 62.
If the valve guides 26a are provided at the same spacing as j, the valve guides 26a can be reliably transported from the parts distribution device 16 to the automatic supply device 10. Further, a lower positioning plate 78 and a chuck pocket 9 are connected to the upper positioning plate 74 through flexible tubular bodies 82a to 82h.
Press-fit attachment 68a of press-fit device 68 to 8a
Holes 80a to 80h and 114a to 11 whose respective spacing distances are selected corresponding to holes 80a to 68h.
4h is provided. Therefore, the valve guide 26a fed into the chuck pocket 98a from the upper positioning plate 74 via the lower positioning plate 78 can be accurately fed into the press-fitting attachments 68a to 68h of the press-fitting device 68. Moreover, the automatic supply device 10
The first and second parts delivery mechanisms 69 that constitute the
By using a and 69b, it is possible to correspond to two different types of cylinder heads.

Furthermore, when the valve guides 26a, 26b, etc. are press-fitted into various types of cylinder heads, the lower positioning plate 78 and the chuck pocket 98 are used in the first parts delivery mechanism 69a described above.
a and 98b may be replaced in accordance with the desired cylinder head. That is, in the parts distribution device 16, for example, the distribution plate 56 constituting the arrangement mechanism 30a is replaced with one in which the number of openings 60a to 60b is selected to a desired number corresponding to each cylinder head. By adjusting the position of the locking member 52 constituting the member 46, the number of valve guides 2 corresponding to the desired cylinder head can be adjusted.
6a can be delivered to the automatic feeding device 10. Therefore, a desired number of valve guides 26a will be fed to the upper positioning plate 74 of the automatic feeding device 10. Therefore, the lower positioning plate 78 is inserted into the holes 8 in accordance with the spacing of the valve guides 26a in the desired cylinder head.
If the valve guide 26a is replaced with one in which the spacing is adjusted from 0a to 80n, the valve guide 26a is sent out from the upper positioning plate 74 to a new lower positioning plate 78 via the tubular bodies 82a to 82n, respectively, and the valve guide 26a is The spacing will be adjusted to accommodate the new cylinder head. Furthermore, if the holes 114a to 114n of the chuck pocket 98a are replaced with a chuck pocket 98a corresponding to a new cylinder head in the same manner as the lower positioning plate 78, the valve guide 26a can be inserted from the lower positioning plate 78 into the new chuck pocket 98a. The press-fitting attachment 68a of the new press-fitting device 68 is fed out from this chuck pocket 98a as described above.
The valve guide 26a will be fed to the valves 68n to 68n.

On the other hand, it goes without saying that when feeding the other valve guide 26b to a new press-fitting device 68, this can be done simply by replacing the lower positioning plate 78 and the chuck pocket 98b.

Further, since the lower positioning plate 78 is inclined with respect to the horizontal direction, the chuck pocket 98a is inclined toward the axial direction of the rotating shaft 86a (see FIG. 6). Therefore, compared to a case where the chuck pocket 98a swings between a horizontally oriented parts receiving position and a vertically oriented parts delivery position, it is possible to reduce the rotational load acting on the rotating shaft 96a at once. At the same time, it can be easily downsized.

Furthermore, since the two chuck pockets 98a, 98b swing integrally through the single cylinder 100, the number of drive sources can be effectively reduced, and the rotational load acting on each rotating shaft 96a, 96b can be reduced. It has the effect of gaining.

[Effects of the Invention] As described above, according to the present invention, after the first positioning plate receives a predetermined number of parts that are fed from the parts arrangement device at regular intervals, the parts are transferred to the loading device. The parts are spaced and aligned at a desired interval by a second positioning plate to correspond to the above, and furthermore, the parts are fixed in position by the first and second holding members and sent to the loading device, so that the feeding operation of the parts is performed extremely reliably. I can do it. Furthermore, when parts are to be loaded onto various different workpieces, this can be easily done by simply replacing the second positioning plate and the first and second holding members that constitute the device in accordance with the different workpieces. becomes possible. Therefore, compared to the conventional method where feeding devices are provided for each different workpiece,
The manufacturing cost of the device can be reduced at once, and the area occupied by the device in the workplace can be made as small as possible.

Although the present invention has been described above with reference to preferred embodiments, the present invention is not limited to these embodiments, and various improvements and changes in design can be made without departing from the gist of the present invention. Of course.
