Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is directed to a component supply device, in particular, a configuration in which a component to be supplied comes into contact with the surface of a conveying path, and the component is conveyed in a predetermined direction due to the weight of the component or vibration of the surface of the conveying path. The present invention relates to an improved structure for neutralizing static electricity generated by friction between a supplied component and the surface of a conveying path in the component supply device.

[0002]

[Prior art]

 As a component supply device having a structure in which the components to be supplied come into contact with the surface of the transportation path, there is a parts feeder that supplies the components by vibrating the surface of the transportation path. For example, when a lightweight plastic (polycarbonate, etc.) molded product is supplied with this parts feeder, the transport road surface and the plastic molded product rub against each other, causing a positive and negative charge respectively. Then, the electric charge on the conveying road surface and the electric charge of the plastic molded product are attracted by the coulomber, and the plastic molded product sticks to the conveying road surface, and does not move inside the conveying path, resulting in a marked decrease in the component supply capability.

[0003]

[Problems to be solved by the device]

 Conventionally, an ionized air blower that generates positive and negative ions by corona discharge has been used to remove static electricity from an insulator (neutralize the charged electric charge). , Positive and negative ions do not reach the contact surface between the transportation path and the supply parts. In the figure, 31 is the surface of the conveying path, 32 is a component to be supplied, and 33 is positive and negative ions supplied by an ionized air blower (not shown).

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the component supply device of the present invention according to claim 1 is configured such that a component to be supplied comes into contact with the surface of the conveyance path and the weight of the component itself or vibration of the surface of the conveyance path causes In a component supply device configured to convey the above-mentioned components in a predetermined direction, a means for forming positive and negative ions by corona discharge etc. by providing a hole in the surface of the conveying path with which the above-mentioned supply components come into contact, and the means. Means for spraying the positive and negative ions generated by the above through the hole provided on the surface of the transport path to the surface of the component.

Further, in order to solve the above-mentioned problems, in the component supply device of the present invention according to claim 2, the component to be supplied comes into contact with the surface of the conveyance path, and the weight of the component or the vibration of the surface of the conveyance path is shaken. In a component supply device configured to convey the above-mentioned components in a predetermined direction by movement or the like, a portion (A) made of a material that is positively charged when the surface of the conveyance path with which the above-mentioned supply components come into contact is rubbed with the component. And parts (B) made of a material that is negatively charged when it rubs against the parts are alternately arranged.

[0006]

[Action]

 According to the component supply device of the present invention according to claim 1, the charges on the surface of the supply component, which is closely adhered to the surface of the transport path, are neutralized by the positive and negative ions sent through the holes on the surface of the transport path. It

Further, according to the component supply device of the present invention according to claim 2, the surface of the supply component, which is in close contact with the surface of the conveying path, alternately touches the above-mentioned portions A and B as the component moves, and wears. The positive and negative charges due to rubbing are suppressed.

[0008]

【Example】

 Hereinafter, the present invention will be described in detail based on embodiments.

FIG. 1 is a block diagram of an embodiment of the present invention according to claim 1.

In the figure, 11 is the surface of the conveying path and 12 is the parts to be supplied. The component 12 moves while touching the transport path surface 11. At this time, the parts move due to gravity drop due to their own weight or vibration of the conveyance road surface in the parts feeder. Static electricity is generated on the surface of the component 12 that is in close contact with the transport path surface 11 due to friction with the transport path surface. However, it is supplied from an ionized air blower 14 (a device that generates positive / negative ions by corona discharge and blows out air 15 containing the generated positive / negative ions) through a hole 13 provided in the surface 11 of the transport path. Charges on the surface of the component are neutralized by positive and negative ions.

FIG. 2 is a block diagram of an embodiment of the present invention according to claim 2.

In the figure, 21 is the surface of the conveying path, and 22 is the parts to be supplied. The transport path surface 21 is formed by alternately arranging portions 23 made of a material that is positively charged when it rubs against a component and portions 24 made of a material that is negatively charged when rubbed against a component. Similar to the above, the component 22 moves while touching the transport path surface 21. Static electricity is generated by friction between the surface of the component 22 that is in close contact with the transport path surface 21 and the transport path surface 21. However, as the part moves, the surface of the part that comes into close contact with the surface of the conveying path alternately contacts the part 23 made of a material that is positively charged and the part 24 made of a material that is negatively charged when the part is rubbed, so that the part is charged. The amount of charge does not increase.

When the component is a molded product of polycarbonate, Duracon is a material that is positively charged when it is rubbed with the component, and vinyl chloride is a material that is negatively charged when the component is rubbed.

In this way, the attraction force between the supplied charges of the component 12 or 22 and the charge of the transport path surface 11 or 21 is weakened, and the component does not stick to the transport path surface due to the Coulomb force.

[0015]

[Effect of device]

 As described in detail above, according to the present invention, in the component supply device, the components do not stick to the conveyance road surface due to the Coulomb force that attracts the electric charges charged by the friction between the components and the conveyance path surface, and the component supply capability is eliminated. Can be improved.
