Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a parts feeder for conveying parts, and more particularly to a parts feeder for applying powder or the like to the parts being conveyed.

[0002]

[Prior art]

 For example, in cold forging, molybdenum disulfide is applied to the surface of the material as a pretreatment for forging, and a lubrication treatment is applied. In this lubrication process, powdery or solid molybdenum disulfide and the raw material parts are put together in a tumbling device, and the tumbling device is rotated to deposit molybdenum disulfide on the surface of the raw material.

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

[0004]

[Problems to be solved by the device]

The parts feeder as described in the above-mentioned publication is used to convey the material parts in the cold forging to the press machine. However, when the material parts are steel, the material surface is as described above. Pretreatment of forging is required to attach molybdenum disulfide to the. Conventionally, molybdenum disulfide is attached to the surface of the material using a tumbling device as an independent process separate from the forging process. For this reason, the equipment investment becomes large and the work efficiency decreases. An object of the present invention is to solve the above-mentioned problems by providing a parts feeder for conveying parts with a function of applying powder or the like to the parts being conveyed.

[0006]

[Means for Solving the Problems] The present invention has a conveying track composed of a spiral peripheral circuit having a gentle upward slope from a bottom surface to an inner peripheral surface, and a delivery path for conveying parts is provided at an upper end portion. In the formed parts feeder, the parts feeder is characterized in that a rough surface is formed on a surface of the transfer truck for holding a coating material for the transfer parts.

[0007]

[Action]

 Conveyance parts put on the bottom of the parts feeder rise while changing their posture along the conveyance track, and their surfaces are covered with the coating agent adhered and held on the rough surface of the conveyance track during the movement.

【Example】

 1 and 2 show an embodiment of the present invention, and FIG. 1 is a partial sectional view taken along line XX of FIG. 2 showing a plan view. The parts feeder is composed of a vibrating drum 1 and a vibrating device 2. The vibrating drum 1 is composed of a vortex-shaped peripheral circuit having a gradual upward slope from the chevron-shaped bottom surface 3 that receives the work W, which is a conveying component, along the inner peripheral surface. And a delivery path 6 for transporting components is formed at the upper end portion. Rough surfaces 5 are formed on the side walls and the bottom wall of the transport truck 4. The rough surface 5 may be formed by attaching a shark-skin-like paper, cloth, or resin film to the transport track 4, or using a knitted product having a rough surface such as a cloth belt.

Next, the operation of this parts feeder will be described. When, for example, a cylindrical work W is put into the bottom surface 3 of the vibrating drum 1 from a work supply device (not shown) and the vibrating device 2 is operated, the work W changes its posture while the work W moves from a spiral circuit. 2 is lifted up, and as shown by the arrow in FIG. 2, it is sent out from the sending path 6 in a posture along the side wall of the carrying truck 4. On the other hand, molybdenum disulfide M is attached and held on the rough surfaces 5 formed on the side wall and the bottom wall of the transport truck 4. The molybdenum disulfide M is supplied by supplying molybdenum disulfide M powder to the bottom surface 3 or supplying a solid body to the bottom surface 3. When the solid molybdenum disulfide M is used, if it has the same shape as the work W, it is sent out to the next step from the delivery path 6 together with the work W, so it must be kept in the vibrating drum 1. In FIGS. 1 and 2, a cubic molybdenum disulfide M whose one side is longer than the diameter of the cylindrical work W is used. 7 is attached.

The work W and molybdenum disulfide M put on the bottom surface 3 of the vibrating drum 1 ascend the transport truck 4 as the vibrating drum 1 vibrates, and the work W adheres to the rough surface 5 during its movement. The surface is coated with the molybdenum disulfide powder. On the other hand, a cube of molybdenum disulfide M also moves up the transport truck 4 and is rubbed against the rough surface 5 during its movement to supply molybdenum disulfide to its surface. FIG. 3 shows a cross section taken along the line YY of FIG. The scraping tool 7 allows the work W to pass therethrough, but is set to have a size that hits the cubic molybdenum disulfide M, so the molybdenum disulfide M is scraped off to the lower stage of the transport truck 4 as shown by the arrow. Circulate the transport truck 4.

4 and 5 show another embodiment. FIG. 4 shows a partial plan view, and FIG. 5 is a partial sectional view taken along the line ZZ of FIG. In this embodiment, a notch portion 8 is formed in the upper transport track 4 by cutting out a part of the inner side thereof to form an inclined surface. Although the work W passes through the notch 8 along the side wall of the transport truck 4, the large-diameter molybdenum disulfide M drops from the notch 8 to the lower stage of the transport truck 4 as shown by the arrow, and It is circulated in 4 and rubbed against the rough surface 5, and is held in powder form.

As described above, since it is possible to impart a lubricant application function to the parts feeder used in the forging line, it is not necessary to perform a separate lubrication step for pretreatment, and therefore, No equipment is required and productivity can be improved. In the above embodiments, the parts feeder used in the cold forging line was described, but the present invention is not limited to this, and for example, when waxing the surface of fruits such as tangerines and apples. Can also be applied to.

[0013]

[Effect of device]

 In the present invention, it is possible to add a coating function to the surface of a transport component by simply forming a rough surface on the transport track of a conventional parts feeder and holding the coating agent, and a coating device is required separately from the transport device. Not only that, less capital investment is required and productivity can be improved.
