Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for aligning and supplying parts suitable for use in a work place where a large number of parts are used, such as an automobile assembly plant.

[0002]

2. Description of the Related Art Among parts, a method of aligning and supplying small parts having a so-called round shape, such as a tube-shaped part, a rod-shaped part or a spherical part, to a necessary place is generally known. It is often done with a vibrating parts feeder or various hopper feeders. 6 to 9 show this. The one shown in FIG. 6 is called a vibrating ball hopper feeder.
The component 5 is supported by the leg 3 so as to give vibration, and the component 5 is placed in the groove 4 provided inside the ball 1, and the component 1 is sequentially moved by giving vibration to the ball 1 and discharged from the discharge port 6. It was done like this.

The one shown in FIG. 7 is called a straight-moving vibration hopper feeder, which supports a hopper 7 on a base 8 so that vibration can be given in the direction of the arrow, and by this vibration, the parts 5 in the hopper 7 are fed. It is designed to be discharged from the chute 9. The one shown in FIG. 8 is called an intermediate plate hopper feeder, and the hopper 10 is supported by an arm 11 provided at the bottom of the hopper 10 so as to be rotatable around the end 12 of the arm 11 in the direction of the arrow. A grooved feed passage 14 is formed in the center of the inside of the grooved feed passage 14, and the component 5 in the grooved feed passage 14 is sent out from the tip of the grooved feed passage 14.

The one shown in FIG. 9 is called a reciprocating funnel hopper feeder, and has a funnel-shaped hopper 15 and a pedestal 16
The feeding pipe 18 is inserted into the opening 17 of the hopper 15, and the feeding pipe 18 is reciprocated in the arrow direction (vertical direction) by a drive mechanism (not shown).
In this device, by reciprocating the feed pipe 18, the feed pipe 18 projects into the hopper 15 and pushes up the component 5.
Further, since the hopper 15 also follows this, the parts 5 are positively discharged.

[0005]

The various conventional feeders described above have the following problems. That is, the vibrating ball hopper feeder is often used especially for aligning and feeding round parts, but as the outer dimensions and weight of the parts increase, the ball hopper and vibrating body become larger. When setting it, a large floor space is required as a whole. Further, since noise and vibration become large, a large-scale soundproof and vibration damping device is required.

Due to the shape and size of the parts (particularly a tube-shaped part whose length is small with respect to the outer diameter), the parts fit together and get stuck on the chute of the feeder (see FIG. 10).
Oscillating pieces of various hopper feeders (feed pipe in the example of FIG. 9)
May engage with the parts and squeeze together, creating a wedge and becoming stuck (see Figure 11). In any state, it becomes impossible to supply the parts, which is a major factor for lowering the operation rate of the automated equipment.

As a prior art of an aligning and feeding apparatus for parts, there is one disclosed in Japanese Utility Model Publication No. 3-40814. Since the technology disclosed in this publication is made for the purpose of favorably supplying the head-equipped parts, it is possible to obtain an excellent effect in the supply of the head-equipped parts. It is not always possible to expect an excellent effect with respect to the parts targeted by the present invention, which are so-called round products.

As another example of the prior art, Shoukai 60-1
There is a technology disclosed in Japanese Patent No. 22726, but since the target parts of this technology are steel parts and have a spherical shape, the discharge of a member having such a shape from the hopper is good. Although it is carried out, there is a problem that it cannot be applied as it is in the case of the target part of the present invention in which the same round product is mixed with various shapes.

The present invention has been made in view of this point, and it is an object of the present invention to provide a device which can stably supply even a component having a non-uniform shape while having a relatively simple structure.

[0010]

Means for Solving the Problems As a means for solving the above problems, the present invention provides a front plate which is bent obliquely rearward from an intermediate portion and is provided with a front plate which is separated from the rear plate by a predetermined distance. On both sides of the rear plate and the front plate, side plates having a substantially triangular shape whose front side is aligned with the front plate and whose rear side is bent backward are joined to form a funnel-shaped hopper. A notch is provided in the upper part of the front plate, and a flap that rotates around an axis that spans the upper end of the front plate is attached to the notch, and the flap is connected to the cylinder mechanism. A work guide is provided between the plates so as to be vertically movable.

[0011]

With this construction, when the parts are clogged due to improper posture, and when the parts do not come out of the hopper, the work guide is raised to push up the parts, and in this state, the parts are flapped. By pressing, the parts will be in a position suitable for exiting the hopper and will be discharged to the chute side.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. 20 is a rear plate, in the middle of which, that is, a code
The light is refracted obliquely rearward from the refraction portion indicated by 21. Reference numeral 22 denotes a front plate whose lower end is matched with the lower end of the rear plate 20 and whose upper end is at the same height as the bent portion of the rear plate 20. The rear plate 20 and the front plate 22 are provided at a lower portion with a predetermined gap (a size suitable for the component 23 to pass through), and the component 23 passes through here as described later.

On both sides of the rear plate 20 and the front plate 22, the front side is the front plate 22.
The side plates 24 and 25 having a substantially triangular shape, which are fitted to the rear plate 20 whose rear side is bent backward, are joined together, thereby forming a funnel-shaped hopper 26. Inside the hopper 26, a rod-shaped holder 27 is bridged in the vicinity of the upper end of the rear plate 20, and a plurality of rails 28 are incorporated downward in the holder 27 to form wavy unevenness. I am doing it.

A notch 29 is provided in the upper portion of the front plate 22, and a flap 31 that rotates around a shaft 30 spanning the upper end of the front plate 22 is attached to the notch 29. There is. The shape of the flap 31 is not a rectangle but a trapezoid that is long on the front side and short on the other side in the drawing. The shaft 32, which is the center of rotation of the flap 31, has an arm 32, a shaft 33 and an arm
The rod 36 of the cylinder mechanism 35 is connected via 34. The lower portion of the cylinder mechanism 35 is attached to the front plate 22 via a bracket 37.

A gap 38 is formed between the lower portions of the front plate 22 and the rear plate 20 which face each other. A work guide 40 having an upper surface formed into a slope 39 is mounted in the gap 38, and two left and right guide shafts 41 are fitted in bearings 42 to be supported so as to be vertically movable. The part of the work guide 40 has an axis
A bracket 44 is attached by 43, and a shaft 45 fixed to the bracket 44 is connected to a shaft 47 of a cylinder mechanism 46. As a result, when the cylinder mechanism 46 operates, the work guide 40 can move up and down.

One end of a chute 48 is connected to one side of the lower portions of the front plate 22 and the rear plate 20 facing each other so that the chute 48 is flush with the upper surface of the work guide 40 in the space 38. . As a result, when the component 23 exists on the upper surface of the work guide 40, it rolls on the slope 39 on the upper surface of the work guide 40 and reaches the chute 48.

In this device constructed as described above, basically, the part 23 that has entered the hopper 26 from above rolls on the wavy unevenness by the plurality of rails 28 without applying any external force. The rolling motion of the slope 39 on the upper surface of the work guide 40 reaches the chute 48, but it may not be so smooth depending on the condition of entering the hopper 26. This will be explained.

First, when the component 23 is supplied in a random posture as shown in FIG. 2, a part of the component 23 (reference numeral in FIG. 2).
(Indicated by 23a) rolls on the wavy unevenness formed by a plurality of rails 28 and rolls on the slope 39 on the upper surface of the work guide 40 to reach the chute 48. If part 23 (shown by reference numeral 23b in FIG. 3) that cannot be inserted into the void 38 is caught in the middle due to the posture, the cylinder mechanism 46 is activated to raise the work guide 40 as shown in FIG. Let It is to be noted that reference numeral B in FIG. 2 indicates the thickness of the work guide 40. The thickness B is set smaller than the outer diameter of the component 23 and smaller than the height.

When the work guide 40 is lifted in this manner, the part 23b which cannot be put in the space 38 is also lifted together with the work guide 40.
Ascend to the position where the flap 31 of the front plate 22 is provided. At this time, the cylinder mechanism 35 is activated to move the component 23b to the flap 31.
Press with. When this is repeated a proper number of times, the component 23b changes to the prone posture and becomes as shown by the reference numeral 23a, and passes through the gap 38 to reach the chute 48. In addition, work guide
The ascending stroke S of 40 is set to a distance that makes it easy for the component 23 to lie down when dropped.

FIG. 4 shows the part 23b without the space 38.
Shows the position of the rolling motion on the rail 28 and the lifting of the work guide 40. FIG. 5 shows that the component 23b changes its position by the rail 28.

[0021]

As described above, the present invention is an apparatus for aligning and supplying parts which is constructed as described above. Therefore, when the parts flowing from the hopper to the chute are clogged on the hopper side due to their postures, the cylinder mechanism is appropriately operated. By doing so, the posture of the component can be easily changed. As a result, the clogging is cleared and the fluid flows smoothly.
