DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component separating apparatus in which components are entangled or overlap with each other to separate connected or connected components.

[0002]

2. Description of the Related Art In a component transport apparatus for transporting components one by one, if components are entangled or overlap with each other and are connected or connected, it is necessary to separate them. For this reason, as a component separation device, conventionally, connected or connected components are
A method of separating by applying a shock by blowing off with an air jet has been put to practical use. In the present invention, a component is not a component in a narrow sense, but refers to an article that has substantially the same structure, and may be entangled or overlapped with each other to be connected or connected.

[0003]

The separation of parts by applying an impact is effective when parts made of a relatively hard material such as a coil spring are connected to each other. However, a rubber ring made of a flexible material cannot be separated by the impact of an air jet due to a large friction coefficient and elastic deformation of the rubber depending on how the rubber ring is fitted. An object of the present invention is to provide a component separation device that can easily separate components when components having a large friction coefficient or elastic deformation are connected to each other.

According to a first aspect of the present invention, a component separating apparatus sandwiches a component to be transferred on a transfer path between the transfer path and a roller, and connects a plurality of connected components to each other with a roller and a component. Or the transfer path and the parts are separated by friction. That is, due to the speed difference between the transfer path and the roller, a frictional force is applied to the part being transferred, and the parts are separated from each other. For this reason, parts having a large friction coefficient and elastic deformation can be easily separated from each other even if they are connected or connected.

[Claim 2] If the roller is mounted on a swinging member that is swingably attached to a fixed member so that the outer peripheral surface moves in the direction of contact and separation with respect to the transfer path, damage to the parts may occur. And deformation can be prevented.

[Claim 3] When grooves are provided at predetermined intervals on the outer peripheral surface of the roller, problems such as deformation due to torsion of parts can be prevented, and the separating function is increased.

[Claim 4] If a groove having a width in which the component is loosely fitted is provided on the outer peripheral surface of the roller, problems such as deformation due to torsion of the component can be reliably prevented, and the separating function is further increased. .

[Claim 5] If an adjusting means for adjusting the swing range of the roller is provided, the gap between the outer peripheral surface of the roller and the transfer path can be appropriately adjusted according to the size and material of the parts. , Excellent usability.

The vibration-type component supply device A includes a vibration device 2 mounted on a base 20 and a vibration container 21 mounted on the vibration device 2. A large number of components 3 are housed in the vibration container 21. In the present embodiment, the component 3 is a rubber gasket, and the lip 32 extends in an annular shape with a slightly larger diameter from the annular portion 31 having a circular cross section. (See Fig. 3)

A helical component transfer path 22 whose center radius gradually increases upward is provided on the outer peripheral portion of the vibration container 21, and a tip of the component transfer path 22 is a component outlet 23. In this vibration type component supply device A, a large number of components 3 are put in a vibration container 21, and the components 3 are sequentially guided to the component transfer path 22 by vibrating the vibration container 21. The parts 3 arranged in a line on the parts transfer path 22 while moving are
Are supplied to the next process one by one.

The component separating apparatus 1 includes a stand 11 as a fixing member fastened to a base 20, a swing bracket 4 as a swing member which is swingably installed on an upper end of the stand 11, and It comprises a motor 5 and a roller 6 attached to the bracket 4. The stand 11 has a plate shape, and stands upright beside the vibration type component supply device A. The fixing member may be another structure such as a machine frame other than the stand 11.

The stand 11 has a leg 12 having a lower end fastened to a base 20, and an upper end having an inclined surface 14 having an inclined angle rising toward a direction of the vibrating component supply device A via a corner 13. ing.

The swing bracket 4 is formed of a plate having an L-shaped cross section, and one side 41 arranged along the inclined surface 14 is rotatably connected by a hinge 15. The other side 42 of the swing bracket 4 is disposed on the side 41 on the side of the vibrating component supply device A, and
3 is open. A stopper 35 is provided at the end of the inclined surface 14 so that the swing position of the swing bracket 4 can be limited. The stopper 35 is
It has a structure in which a screw is screwed to the inclined surface 14, and the interval h in the normal state can be adjusted arbitrarily.

The motor 5 is mounted on the other side 4 of the swing bracket 4.
The output shaft 51 is disposed above the component transfer path 22 through the shaft hole 43. A rotating shaft 52 is connected to a tip of the output shaft 51, and the tip of the rotating shaft 52 is formed to have a small diameter.
A urethane roller 6 is attached between the rollers 3 and 53. A cover 44 that covers the upper side and the side of the roller 6 is attached to the inner surface of the other side 42. Reference numeral 200 denotes a guide plate arranged in parallel with the roller 6.

The roller 6 is provided with an axial groove 6 on the outer peripheral surface 61.
2 are formed at predetermined intervals. The distance h between the outer peripheral surface 61 and the component transfer path 22 is set to be slightly larger than the height of the component 3 by the screw type stopper 35. The diameter and width of the roller 6, the number of grooves 62, the depth and the width
Is appropriately selected according to the material, size, and shape of the material. In the present embodiment, the width W and the depth D of the groove 62 are set to dimensions that allow one article 3 to be loosely fitted, and the length L between the grooves 62, 62 is 1. It is set to 2-1.5 times.

The operation of the component separating apparatus 1 will be described with reference to FIGS. In order to operate the vibration type component supply device A, the motor 5 is energized to rotate the roller 6. The rotational speed of the roller 6 is set such that the outer peripheral surface 61 is slightly faster than the transport speed of the component 3 in the same direction as the transport direction of the component 3. The components 3 in the vibration container 21 go up the component transfer path 22 sequentially. However, two or more components 3 may be fitted and connected.

As shown in FIG. 3A, the component transfer path 22
When the two parts 3A and 3B, which are overlapped and combined with each other, are conveyed, they come into contact with the outer peripheral surface 61 of the roller 6 and between the component transfer path 22 and the outer peripheral surface 61 as shown in FIG. Be drawn in. At this time, the roller 6 swings and lifts upward as shown in FIG. 3 (c) and FIG. 4 (h → h ′).
At the same time, the weight of the upper part of the hinge 15 is added to the two parts 3A and 3B sandwiched. Therefore, as shown in FIG. 3C, the friction between the outer peripheral surface 61 and the upper component 3A urges the upper component 3A in a direction to separate it from the lower component 3B, and the upper component 3A causes the lower component 3A to move downward. Separate from the part 3B.

As described above, by pressing the component 3 with the roller 6 and applying a twisting force, the overlapping and entangled components can be reliably separated. Also, the outer peripheral surface 61 of the roller 6
By providing the groove 62 in the groove 3, the problem that the torsion of the component 3 cannot be returned can be surely prevented. Further, since the roller 6 is attached by the hinge 15 so that the outer peripheral surface 61 is freely displaceable in the direction of coming and going with respect to the component transfer path 22, deformation of the two components 3A and 3B is restricted, and damage to the component 3 is prevented. You. If the roller 6 is fixed, the two components 3A and 3B are greatly deformed, and an excessive external force is applied to the corners of the groove 62 and the component 3 may be damaged.

The means for disposing the outer peripheral surface 61 in the component transfer path 22 so as to be freely displaceable in the contacting and separating directions is such that a method in which the swing bracket 4 is swingably attached to the stand 11 as a fixing member has a simple structure and is advantageous. However, the roller 6 may be displaceably supported on the component transfer path 22 using a spring.

Next, as shown in FIG. 3D, the upper component 3A fits into the groove 62 and moves forward. Subsequently, as shown in FIG. 3E, the lower component 3B contacts the outer peripheral surface 61 of the roller 6 and pushes the component transfer path 22 rightward in the drawing. When the gap D is set to be larger than the height of the component 3, the lower component 3B is transferred by vibration. As a result, the component 3 that has been coupled and transferred on the component transfer path 22
A and 3B are surely separated, and the parts 3 are transferred to the part outlet 23 one by one. Note that the component transfer path 22 may be a conveyor.
