Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a fixing device for a parts feeder, and is used in a field in which fixing parts for a parts feeder are more rationalized.

(B) Prior Art The parts feeder of the present invention is of the type shown in FIGS. 6 and 7, and the parts feeder main body 2 mainly houses the bowl 1 for housing the parts and the vibration unit. And a delivery pipe 3 extends from the bowl 1. This parts feeder is a general one in which combined vibration of the circumferential direction and the vertical direction is applied to the bowl 1, and is placed on the stationary mount 4. A pedestal 5 is welded to the stationary base 4. Due to the vibration as described above, the parts move on the spiral step 6 and reach the delivery pipe 3.

Parts feeders of this type can be found in Shokai Sho 2-60742.
It was supported by a structure as shown in Japanese Patent Laid-Open Publication No. 4 or 5. In the case of FIG. 4, a bolt 9 having a flange 8 is integrated into a cup-shaped vibration isolating rubber 7 that opens downward, and the bolt 9 is screwed into the bottom plate 10 and locked with a lock nut 11. It is tightened, and the pressing plate 12 is further applied to the upper surface of the anti-vibration rubber 7 and the fixing bolt 13 is screwed into the stationary base 4, thereby fixing the parts feeder to the stationary base 4.

FIG. 5 shows a case in which the auxiliary plate 14 is added to the one shown in FIG. 4, and the tubular portion 15 formed on the auxiliary plate 14 matches the antivibration rubber 7 to more reliably position the antivibration rubber 7. It is supposed to be.

(C) Problems to be solved by the invention In the case as shown in FIGS. 4 and 5, the vibration-proof rubber 7
Needs to manufacture a special part integrated with the bolt 9, which is economically disadvantageous in terms of cost. Then, after screwing the bolt 9 into the bottom plate 10, the holding plate 12 is fixed with the bolt.
Since it has to be tightened at 13, the number of assembling steps is increased and the number of parts is increased, which is particularly disadvantageous in FIG. Further, in FIG. 4, when the elasticity of the vibration isolating rubber 7 decreases, the repulsive force of the vibration isolating rubber 7 in the up-down direction decreases, and eventually the holding effect of the pressing plate 12 becomes weak, and the vibration isolating rubber 7 is There is a risk of shifting on the stationary mount 4.

Furthermore, as an especially important point, the anti-vibration rubber 7 is attached to the stationary mount 4
Since it is a basic method of directly pressing against, it is not possible to secure a sufficient contact area between the anti-vibration rubber and the stationary frame, or even if the auxiliary plate 14 is used, its rigidity is insufficient. As a result, the surface pressure of the auxiliary plate 14 with respect to the stationary base 4 cannot be sufficiently secured over the entire area, and eventually there arises a problem that it cannot withstand the vibration of the parts feeder.

(D) Means for Solving the Problem and Its Action The present invention has been devised by focusing on the above-mentioned problems, in which end plates are adhered to the upper and lower sides of the vibration-proof support rubber and both end plates are attached. A bolt is fixed to the lower end plate, and the lower end plate is inserted into the through hole of the board made of a thick plate to be joined to form a pre-assembly of the vibration-proof support rubber and the board. Has a portion larger than the outer shape of the anti-vibration support rubber, this portion is fixed to the stationary stand at the part protruding from the parts feeder main body, and the upper end plate is fixed to the bottom plate of the parts feeder with bolts. The anti-vibration supporting rubber having end plates with bolts on the upper and lower sides is pre-assembled with the substrate in advance, and the pre-assembled product is fixed to the bottom plate of the parts feeder and also to the stationary mount.

(E) Embodiments Embodiments shown in FIGS. 1, 2, and 3 will be described. The same reference numerals as those used in the description of the prior art are used in the embodiments, but they are specific to the embodiment. Since the above-mentioned members are shown, it should be understood that they are different from those of the prior art.

The parts feeder is arranged on the stationary base 4 by installing the anti-vibration support rubber 8 on the bottom plate 7, and the anti-vibration support rubber 8 has its upper and lower end plates 9 and 12 bonded by vulcanization or the like. It is glued, and each end plate has a bolt 1
0 and 13 are fixed. First, the connection structure of the vibration-proof support rubber 8 and the bottom plate 7 will be described. The bolt 10 penetrates the bottom plate 7, and the nut 11 is tightened there to tighten the vibration-proof support rubber 8 and the bottom plate 7.
Has been integrated with.

A through hole 17 is opened in a board 16 made of a thick plate material, the length of the bolt 13 is made the same as the thickness of the board 16, and the bolt 13 and the board 16 are welded at a portion indicated by reference numeral 18.

A portion of the substrate 16 larger than the outer diameter of the vibration-proof support rubber 8 is projected from the case outer plate 14, that is, the parts feeder main body, and the protruding amount is indicated by reference numeral l. A through hole 20 is opened in this portion 19, and a fixing bolt 21 inserted from there into is screwed into the stationary mount 4. In addition,
A cylindrical case outer plate 14 is fixed to the outer periphery of the bottom plate 7 by screws 15.

The anti-vibration support rubber 8 is a standard part having general versatility as shown in FIG. 3. End plates 9 and 12 are adhered to the anti-vibration support rubber 8, and bolts 10 and 13 are respectively attached to both end plates. They are connected to each other, and a bolt connection is made according to the application to fulfill a cushioning function. In this embodiment, the simplest method of appropriately cutting the lower bolt 13 and welding it to the substrate 16 is adopted.

The anti-vibration support rubber 8 and the substrate 16 are previously integrated as a preliminary assembly, fixed to the bottom plate 7 with the bolts 10 and the nuts 11, then placed on the stationary mount 4, and the fixing bolts 21 attach the parts feeder. Done. Then, the substrate 16 is in a state of being pressed against the stationary frame 4 over the entire area thereof.

(F) Effect Since the anti-vibration support rubber and the substrate are pre-assembled as a pre-assembled product, and one is fixed to the bottom plate of the parts feeder and the other is fixed to the stationary mount, the number of assembling steps is minimized.
Since the pre-assembled product is a combination of the vibration-proof support rubber and the thick plate material, it is possible to minimize the number of parts. What is important here is that the substrate uses the thick plate material. Therefore, even if the board is fastened to the stationary stand with bolts or the like, the board itself is not deformed, and the entire board is in close contact with the stationary stand. Therefore, even if the vibration of the parts feeder reaches the board, Due to the close contact of the whole area, the substrate is not displaced. Further, since the vibration-proof support rubber can use a standard product, it is not necessary to specially manufacture a special part, which facilitates parts procurement and is advantageous in cost.

Since the members placed between the bottom plate of the parts feeder and the stationary stand are inseparable and integral structure such as bolt connection, rubber adhesion, and substrate connection, even if the vibration isolation support rubber is elastic. Even if the characteristics are deteriorated, there is no structural element that shifts when separated, so long-term durability can be secured.
