Description

[Detailed explanation of the invention] (a) Industrial application field This invention relates to a parts feeder, which feeds out while sorting lump-shaped parts made of rubber and flat parts made of metal, for example. It is even more effective if applied in some cases.

(b) Conventional technology There are various parts feeders that are known for feeding only specific parts, and one of them is the part feeder for multiple types of parts that I devised in Japanese Utility Model Publication No. 56-20412. "Feeder"
(B65G47/14) is available. This conventional technique is suitable for selecting different types of parts that do not differ significantly in size or shape, for example, 6 mm and 8 mm projection nuts.

(c) Problems to be solved by the invention Block-shaped parts and flat parts whose dimensions and shapes are significantly different, such as the cylinder 1 shown in Figure 8.
If a lump-shaped rubber bushing 3 with rubber 2 integrated around its outer periphery and a metal flat washer 4 as shown in Fig. 9 are housed in a mixed state in the bowl of a parts feeder, either It is advantageous to select one in a manner that matches the shape of the part.
In the above example of parts, flat washers 4
It is appropriate to pay attention to the characteristics of This is an attempt to solve these problems. In other words, the purpose is to ensure that a specific part is sent out without any problem to subsequent parts.

The important issues that require particular attention are:
The spiral stepped part of the parts feeder is a single smooth sliding surface, on which multiple types of parts move in random order, so it is difficult to sort or select just one of the parts. It is impossible to achieve the complex function of ejecting air while allowing other parts to pass through in one place.

(d) Means for solving the problems In order to solve the above-mentioned problems, the present invention provides a device in which parts are sent out while moving upward along a spiral stepped portion, and the present invention provides a method for discharging parts while moving them upward along a spiral stepped portion. A recess is provided on a part of the sliding surface of the component that almost matches the planar shape of the component and has a depth set to be equal to or slightly larger than the thickness of the component, and the material is fed to the exterior wall board in a continuous state with this recess. An outlet is provided, and a sloped surface is provided on the upstream side of the recess to guide the parts inside the recess toward the delivery port, and when a part is present in the recess, the parts before and after the recess are provided. The sliding surface and the surface of the component form a series of surfaces over which another component of a different shape passes.

(E) Effect With the above-described structure, when a part fits into the recess, the following parts, whether flat washers or rubber bushings, will slide over the top of the fitted part. The parts that have been inserted into the container are allowed to pass through and exit from the outlet through the outlet.

In other words, when a component exists in a recess, the sliding surfaces of the component before and after the recess and the surface of the component form a series of surfaces, over which other components of different shapes pass. Components that are stuck in the recess are guided toward the outlet by the slope of the slope and are discharged to the outside.

(f) Embodiment The illustrated embodiment applies the concept of the present invention to the case of mixed handling of a rubber bushing 3, which is a block-shaped part, and a flat washer 4, which is a flat part, and only the flat washer 4 is handled. The system is designed to successfully send out parts without causing any problems to subsequent parts.

FIG. 2 is an external view of the parts feeder 5, in which a bowl 7 for accommodating parts is placed on a vibrating part 6 that generates combined vibration in the circumferential direction and the vertical direction. FIG. 3 is a plan view of the bowl 7, which is mainly composed of a bottom plate 8 and a circular outer wall plate 9, with a spiral stepped portion 10 along the inside of the outer wall plate 9.
is provided.

The helical stepped portion 10 is provided with a sorting and feeding portion 11 for the flat washer 4, a sorting portion 12 for the rubber bushing 3, and a feeding groove 13 for the rubber bushing 3 in order from the lowest. The sorting unit 12 serves to return the flat washer 4 to the bottom of the bowl 7 and guide only the rubber bushing 3 toward the delivery groove 13, and is not related to the gist of the present invention, so a detailed explanation will be omitted. There is.

To explain in more detail, including FIGS. 1 and 4 to 6, the stepped plate 1 constituting the spiral stepped portion 10
4, the sliding surfaces 15 and 16 are fixed by welding or bolting, and the surfaces are fixed to the component sliding surfaces 17, 16.
18, and the upstream side of each sliding plate has slope parts 19 and 2.
0. A recess 21 is provided between the sliding plates 15 and 16. In other words, the recess 2
1 is formed by recessing the sliding surfaces 17 and 18 of the parts, the depth of which is set to be equal to or slightly larger than the thickness of the flat washer 4, and its planar shape is approximately the same as that of the flat washer 4. It is considered to be a match.

Therefore, when the component is present in the recess, the component sliding surfaces before and after the recess and the surface of the component form a series of surfaces.

The outlet 22 of the flat washer opened in the outer wall board 9 is
As is clear from Figures 4 and 6, the flat washer 4
It has a slit-like shape that allows the passage of the concave portion 21, and is continuous with the concave portion 21. A receiving box 23 fixed to the outer wall board 9 is continuous to the outside of the outlet 22.

As shown in FIG. 3, the slope part 20 is oriented so that an angle α is formed between the slope part 20 and the diameter line. It is designed so that force acts on it. In other words, on the upstream side of the recess 21, the slope portion 20 is provided with an inclination that guides the flat washer 4 inside the recess toward the outlet 22. As is clear from FIGS. 5 and 6, the spiral stepped portion 10 (step plate 14) is sloped so that the outer peripheral side is lower.

In the above embodiment, the sliding plate 1 is used to form the recess.
In the embodiment shown in FIG. 7, the concave portion 21 is formed by making a hole in the stepped plate 14 and attaching a closing plate 24 to the hole. Here, the above-mentioned component sliding surface 1
7 and 18 are present on the surface of the stepped plate 14.

When the bowl 7 in which the rubber bushing 3 and the flat washer 4 are mixed is vibrated, both parts are moved along the spiral stepped portion 10, and the flat washer 4 is in close contact with the stepped plate 14. passes through the component sliding surface 15 from the slope portion 19, falls into the recess 21, moves toward the outer circumference along the slope portion 20, and exits from the delivery port 22 to the receiving box 23. be. Even if the flat washer 4 is present in the recess 21 as shown in FIG.
moves further to the right while sliding on the upper surface of the flat washer 4 from the component sliding surface 17. Further, even if another flat washer moves on top of the flat washer 4 in FIG. 4, it moves in the same way as when the rubber bushing 3 passes. Furthermore, when the rubber bushing 3 moves to a place where the flat washer 4 is not fitted into the recess 21, the recess 21
The bushes that have entered are pushed up out of the recess 21 by the slope 20 and moved onto the sliding surface 18.

(g) Effect of the invention According to the invention, a recess is provided in a part of the component sliding surface of the spiral step, and the recess almost matches the planar shape of the component and its depth is equal to the thickness of the component. or a little larger than that, and on the upstream side of the recess, a slope is given to the slope to guide the parts inside the recess toward the delivery port, and the sliding surface of the parts and the surface of the parts inside the recess are Since this forms a continuous virtual surface, only the parts that fit into the recess can be reliably ejected from the outlet by being guided by the slope of the slope, and further If other parts of different shapes move,
It slides over the parts stuck in the recesses, preventing parts from getting stuck due to parts stagnation without interrupting the flow of parts, and provides smooth operation.

The combination of the block-shaped rubber bushings and the flat washers mentioned above was done because of the need to reduce the number of parts feeders, and in such cases, this If the invention is applied, it will be possible to successfully send out only flat parts and also smoothly transfer rubber bushings, making it extremely useful as a parts feeder for dissimilar parts.
