Description

[Detailed Description of the Invention] The present invention relates to a parts distributing mechanism, and more specifically, the present invention relates to a parts distributing mechanism, and more specifically, for example, rod-shaped parts such as valve guides that are press-fitted into cylinder heads constituting an internal combustion engine are arranged so that their axes are parallel to each other and in a predetermined position. It is possible to reliably supply the parts to a press-fitting device etc. by separating them at desired intervals, and by making it possible to change the spacing and number of the rod-shaped parts, it is possible to supply parts to various different workpieces. Regarding the parts distribution mechanism.

2. Description of the Related Art Generally, automatic transport devices are widely used in factories to automatically transport various parts to work positions when assembling products and the like. That is, even in a single product, a plurality of identical parts are often assembled, and by employing the automatic conveyance device, it is possible to effectively meet the demands for mass production.

A good example of this is a valve guide that is pre-assembled into a cylinder head in order to mount an inlet valve or an outlet valve to the cylinder head of an internal combustion engine. Therefore, if you want to mass-produce cylinder heads, the valve guides should be made one after the other according to the cylinder head.
It is necessary to quickly transport a predetermined number of parts parallel to each other and spaced apart at desired intervals to the assembly work position.

For this reason, various parts distributing devices have been used to arrange and convey a predetermined number of rod-shaped parts such as valve guides. Disclosed. This is shown in FIG.

That is, in FIG. 1, reference numeral 2 indicates a parts dispensing device according to the prior art, and frames 3a and 3b constituting the parts distributing device 2 are erected on a floor surface 4. A table 5 is fixed to the upper part of the frames 3a, 3b, and a plurality of grooves 6a to 6j are formed in the upper surface of the table 5 so as to be equally spaced apart and parallel to each other. Furthermore, a locking plate 8 is locked to the side surface of the table 5.

The locking plate 8 has an abutting portion 10 that is oriented upward and extends laterally with an inclination in the horizontal direction, and a respective groove portion 6.
stoppers 12a to 12i, which are located between a to 6j, are oriented vertically upward, are inclined in the middle, and each has an acute-angled tip, and are adjacent to the stopper 12i and sandwich the groove 6a A plate portion 14 extending upwardly is provided so as to extend upwardly.

Further, a support 16 is erected outside the table 5, and an arm 20 provided with a balance member 18 is swingably attached to the upper part of the support 16. In this case, when the arm 20 swings upward, the tip of the arm 20 is configured to be on the same line as the lower end of the inclined chute 22. Note that the chute 22 is provided with a stopper member 24 that can move forward and backward, and is configured to be able to hold the parts 26 being transported on the chute 22.

In such a configuration, the arm 20 swings upward via the balance member 18, and the arm 20 swings upward via the balance member 18.
When the tip of the chute 22 is located on the same line as the lower end of the chute 22, the stopper means 24 is lowered to slide and convey a predetermined number of parts 26 placed on the chute 22 to the arm 20 side. Among the parts 26 that are conveyed along the slope of the arm 20, the part 2 on the tip side
6 is positioned by coming into contact with the contact portion 10 of the locking plate 8.

Next, when the arm 20 is swung downward, the parts 26 are displaced integrally with the arm 20, and the parts 26 on the tip side are displaced along the shape of the abutment part 10, so that each part 26 is stoppa 1
2a to 12i, and supplied into the grooves 6a to 6j of the table 5.

Therefore, the parts 26 accommodated in each of the grooves 6a to 6j are transported to a desired assembly work position via a chute or the like (not shown).

However, in the prior art described above, the stopper 1 is moved with the plurality of parts 26 in contact with each other.
It is integrally distributed via 2a to 12i.
For this reason, it is not possible to freely select the spacing between the grooves 6a to 6j, and for example, when separating the parts 26 for a considerable distance depending on the assembly work position,
It has been pointed out that the above-mentioned parts distributing device 2 has a disadvantage that it is extremely difficult to deal with. Moreover, when trying to convey the part 26 quickly, especially when the part 26 is small in length, the desired groove 6a
There is a risk that the water will not be reliably and smoothly supplied to the parts 6j to 6j. Therefore, there are disadvantages in that transportation defects are likely to occur and efficient assembly work cannot be achieved.

The present invention has been devised to overcome the above-mentioned disadvantages, and includes forming parts insertion openings at different heights and spaced apart at predetermined intervals in a distribution plate that is inclined with respect to the vertical direction. , a parts conveyance path is provided below the distribution plate at a position corresponding to each of the openings, and the parts conveyed onto the distribution plate are conveyed horizontally to the openings sequentially starting from the uppermost part. By dropping and supplying each part onto the desired conveyance path through the parts, it is possible to smoothly and reliably distribute and arrange a predetermined number of parts.Moreover, when the number of parts to be distributed and the spacing between them are different, The number and spacing of the openings provided in the distribution plate can be selected, and the object is therefore to provide a parts distribution mechanism that is extremely versatile.

In order to achieve the above object, the present invention includes a main body section provided with a plurality of parts conveyance paths that are inclined and parallel to the vertical direction, and a main body section that is attached to the upper surface of the main body section and has a plurality of parts conveyance paths that are parallel to each other and inclined with respect to the vertical direction. a distribution plate forming a plurality of openings for inserting parts corresponding to the path and whose height positions are selected according to the shape of the parts; and a predetermined number of parts are placed on one end side of the distribution plate in the inclination direction. It is characterized by comprising a distribution member forming a part fitting groove for oriented and aligning, and an actuator capable of moving the distribution member in a direction perpendicular to the inclination direction.

rotates in the direction opposite to the arrow, and furthermore, the rotation shaft 118b on which the pinion 120 is provided and the rotation shaft 118a engaged with it via the respective gears 122a and 122b rotate in the direction opposite to the arrow. Therefore, the pocket bodies 126a and 126b, which are attached to the respective rotating shafts 118a and 118b via the arm members 124a and 124b, are oscillated to a position facing the lower positioning plate 94, and the parts distributing mechanism The valve guides 38a and 38b are now on standby to receive the valve guides 38a and 38b conveyed via the valve guides 40a and 40b.

On the other hand, the press-fitting device 96 is connected to the desired valve guide 38.
After receiving the valve guides a and 38b, the valve guide 3
8a and 38b are press-fitted into a cylinder head (not shown).

Above, the work of sending the valve guides 38a, 38b conveyed via the parts distribution mechanisms 40a, 40b to the press-fitting device 96 via the supply mechanism 42 has been described, but other parts distribution mechanisms 40
It will be easily understood that the work of feeding the valve guide to the press-fitting device (not shown) via the valve guides c, 40d and the supply mechanism 42a is performed in the same manner as described above.

In this case, according to the present invention, for example, the valve guides 38a that are sequentially transported via the parts feeder 36a can be separated for a predetermined period and sent to the supply mechanism 42 reliably and smoothly. That is, as described above, the parts distribution mechanism 40a is supplied from the parts feeder 36a via the tubular body 46a.
The valve guide 38a supplied to the distribution member 60 constituting the parts distribution mechanism 40a is accommodated in a fitting groove 62 of the distribution member 60 along the slope of the parts distribution mechanism 40a, and a predetermined number of valve guides 38a are accommodated in the fitting groove 62 of the distribution member 60. Valve guide 38a is now coaxially aligned. Therefore,
When the distribution member 60 is displaced in the direction of arrow A under the driving action of the cylinder 56, the valve guides 38a accommodated in the fitting grooves 62 of the distribution member 60 are sequentially moved from the distribution plate to the valve guide 38a located at the uppermost position. The liquid enters into the openings 76a to 76h of the plate 50 and falls and is supplied to the grooves 52a to 52h of the plate body 50. In this way, the plurality of valve guides 38a coaxially arranged on the vertically oriented and inclined distribution plate 72 are conveyed horizontally to a predetermined position via the distribution plate 72, starting from the uppermost valve guide 38a. Grooves 52a to 5
2h, the valve full guide 38a
can be reliably dropped and conveyed into the grooves 52a to 52h.

Furthermore, in this case, the intervals between the openings 76a to 76h of the distribution plate 72 are the same as those of the grooves 52a of the plate body 50.
For example, if the opening 76b is provided corresponding to the groove 52c or 52d, the spacing between the adjacent valve guides 38a and 38b can be easily adjusted. Become. Therefore, the parts distribution mechanism 40a according to the present invention can be replaced with the parts automatic arrangement and supply device 30 shown in this embodiment, and has the effect that it can be easily incorporated into a supply device for aligning and feeding various rod-shaped parts. is obtained.

As described above, according to the present invention, the rod-shaped parts conveyed via a parts feeder or the like are coaxially aligned on the vertically oriented and inclined distribution plate, and then the rod-shaped parts are horizontally aligned. While being oriented and moved, it is sequentially supplied to a desired conveyance path through openings provided at the same height as the respective rod-shaped parts provided on the distribution plate and spaced apart at a predetermined interval. Therefore, a plurality of rod-shaped parts can be reliably fed one by one onto a desired conveyance path starting from the uppermost rod-shaped part, and the rod-shaped parts can be efficiently fed to a predetermined work position. Moreover, by selecting various spacings between the openings provided in the distribution plate, the spacing between the distributed parts can be easily changed, making it possible to apply it to a variety of different parts conveying operations, making it extremely versatile. The effect is that it is possible to provide a parts distributing mechanism with a certain degree of accuracy.
