Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parts feeder for transferring parts, and more particularly to a parts feeder for applying powder or the like to a part being transferred.

[0002]

2. Description of the Related Art For example, in cold forging, as a pretreatment for forging, molybdenum disulfide is applied to the surface of a material and lubricated. In this lubrication treatment, powdery or solid molybdenum disulfide and a material component are put together in a tumbling device, and the tumbling device is rotated to cause molybdenum disulfide to adhere to the material surface.

In Japanese Utility Model Laid-Open Publication No. 3-53922, there is provided a conveying track composed of a spiral peripheral circuit having a gentle upward gradient from the bottom surface to the inner peripheral surface, and a delivery path for conveying parts is formed at an upper end portion. A part feeder is described in which a narrow groove for discharging dust is formed along a spiral peripheral circuit.

[Problems to be solved by the invention]

[0005] The parts feeder as described in the above-mentioned publication is used to convey a material part in a cold forging to a press machine. Pretreatment of forging for attaching molybdenum disulfide is required. Conventionally, molybdenum disulfide is adhered to the material surface using a tumbling device as an independent process separate from the forging process. For this reason, the capital investment becomes large and the work efficiency is reduced. SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-described problems by providing a parts feeder for conveying parts with a function of applying powder or the like to the parts being conveyed.

[0006]

SUMMARY OF THE INVENTION The present invention has a transport track composed of a spiral peripheral circuit having a gentle upward gradient from the bottom surface to the inner peripheral surface, and forms a delivery path for transport components at an upper end portion. In the above-mentioned parts feeder, a rough surface for holding a coating material for a transport part is formed on a surface of the transport track.

[0007]

The conveyed parts placed on the bottom of the parts feeder rise while changing their attitude along the conveyer track, and the surface is coated with the coating agent adhered and held on the rough surface of the conveyer track during the movement. .

1 and 2 show an embodiment of the present invention. FIG. 1 is a partial sectional view taken along line XX of FIG. 2 showing a plan view. The parts feeder includes a vibrating drum 1 and a vibrating device 2. The vibrating drum 1 has a spiral peripheral circuit having a gentle upward gradient from a mountain-shaped bottom surface 3 that receives a workpiece W as a transport component along an inner peripheral surface. And a delivery path 6 for a transport component is formed at the upper end. The transport truck 4 has rough surfaces 5 on its side and bottom walls.
To form As the rough surface 5, paper, cloth, or a resin film having a shark-skin-like surface may be attached to the transport track 4, or a knitted product having a rough surface such as a cloth belt may be used.

Next, the operation of the parts feeder will be described. When, for example, a cylindrical work W is put into the bottom surface 3 of the vibration drum 1 from a work supply device (not shown) and the vibration device 2 is operated, the work W
The transport track 4 having a spiral circuit is lifted up, and is sent out from the delivery path 6 in a posture along the side wall of the transport track 4 as shown by an arrow in FIG. On the other hand, molybdenum disulfide M is adhered and held on the rough surfaces 5 formed on the side and bottom walls of the transport truck 4. The supply of the molybdenum disulfide M is performed by supplying the powder of the molybdenum disulfide M to the bottom surface 3 or supplying the solid body to the bottom surface 3. In the case where molybdenum disulfide M as a solid body is used, if the shape is the same as that of the work W, the work W is sent out from the delivery path 6 to the next step together with the work W. In FIGS. 1 and 2, a cubic molybdenum disulfide M having a side length larger than the diameter of the cylindrical workpiece W is used.
At the upper part of the transport track 4, a stripper 7 for returning it to the lower transport track 4 is attached.

The work W and the molybdenum disulfide M loaded on the bottom surface 3 of the vibration drum 1 rise on the transport track 4 with the vibration of the vibration drum 1, and the work W adheres to the rough surface 5 during its movement. The surface is coated with molybdenum disulfide powder. On the other hand, a cube of molybdenum disulfide M also rises on the transport track 4 and is rubbed on the rough surface 5 during its movement to supply molybdenum disulfide to the surface. FIG. 3 shows Y in FIG.
3 shows a cross section along the line -Y. The wiping tool 7 allows the workpiece W to pass through, but is set to a dimension corresponding to the cubic molybdenum disulfide M, so that the molybdenum disulfide M is blasted to the lower stage of the transport truck 4 as shown by the arrow, Circulate on the transport track 4.

FIGS. 4 and 5 show another embodiment. FIG. 4 is a partial plan view, and FIG. 5 is a partial cross-sectional view along the line ZZ in FIG. In this embodiment, a notch 8 is formed in the upper transport track 4 to form an inclined surface by cutting a part of the inner side thereof. The work W passes through the notch 8 along the side wall of the transport truck 4, but the molybdenum disulfide M having a large diameter falls from the notch 8 to the lower stage of the transport truck 4 as shown by an arrow, and 4 circulates through the rough surface 5
And is kept in powder form.

As described above, a lubricant application function can be provided to the parts feeder used in the forging line, so that it is not necessary to perform a separate lubrication step for pre-processing, and equipment for this is also required. This is unnecessary, and productivity can be improved. In the above embodiment, the parts feeder used for the cold forging line was described.However, the present invention is not limited to this.For example, when waxing fruits such as tangerines and apples, etc. Can also be applied.

[0013]

[Effects of the Invention] The present invention makes it possible to impart a coating function to the surface of a conveyed component simply by forming a rough surface on the surface of a conveyer track of a conventional parts feeder and holding the coating agent, thereby enabling the transfer device to be provided with This eliminates the need for a separate coating device, reduces capital investment, and improves productivity.
