DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component supply device for supplying components to a working device or the like.

[0002]

2. Description of the Related Art As a component supply device for supplying a component to a working device or the like, for example, a device for supplying a core (winding core) around which a wire is wound to a winding device is known.

FIG. 4 shows this conventional component supply device (core supply device). As illustrated, the component supply device includes a bowl-shaped feeder 101. A core 103, which is a component supplied (conveyed) by a component supply device, is supplied from a hopper 102 to a bottom surface portion 101 </ b> A of the feeder 101. A spiral component guide path 101B extending from the bottom surface 101A to the upper edge is formed on the inner peripheral surface of the feeder 101. When the vibration generator 105 controlled by the vibration controller 104 causes the feeder 101 to vibrate, the core 103 is moved by the vibration along the component guide path 101B.
It is guided from 01A to the upper edge. A plurality of sorting members 101C are provided at key points of the component guide path 101B. This sorting member 101C is
Core 1 that corrects the posture of 3 or the posture is not corrected

[0004]

However, the conventional parts supply apparatus has the following problems.

[0005] First, the core 103 is carried into the feeder 1 from the hopper 102 and the component guide path 101 of the feeder 1 is provided.
In each step such as the transfer along B, static electricity is charged, so that the transfer operation (for example, the work of correcting the posture of the core 3 by the distribution member 101C and the distribution operation) may not be performed smoothly.

Second, since the component guide path 101B is long from the bottom 101A of the feeder 101 to the upper end, it takes a long time to convey. Also, the core 103
In order to continuously supply the components 103 to the component supply path 106, the core 103
If the component guide path 101B is long, it is necessary to provide a large amount of cores 3 on the component guide path 101B, and the efficiency is low (note that in FIG. (Not shown).

The present invention has been made in view of such a problem, and in a component supply device for supplying components to a working device or the like, it is possible to effectively prevent charging of components.
It is an object of the present invention to provide a component supply device capable of realizing an efficient transfer operation in a short time.

[0011]

According to the first aspect of the present invention, when a component to be conveyed is carried into the component carrying-in section, it is introduced into the air carrying path by the component introducing means, and the component is passed through the air carrying path by the air flow. It is conveyed to the transport path and supplied from the component transport path to a working device or the like. As described above, a part of the transport of the parts is performed at a high speed by the air flow, so that the transport time of the parts can be reduced accordingly. Also, since the component transport path can be shortened by the air transport path, even if components are transported at short intervals on the component transport path so that components are supplied without interruption, the number of required components is small. , Work efficiency is enhanced. Therefore, for example, the component transfer operation to the working device can be performed extremely efficiently in a short time.

According to the second aspect of the present invention, since air ions are contained in the air flow in the air conveyance path, when the parts conveyed in the air conveyance path are charged, this charge is neutralized by the air ions. , Will be removed. Therefore, the transfer of the components on the component guide path and various operations after the transfer are smoothly performed without causing any trouble due to the charging of the components.

The certainty of the removal is increased.

[0014]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a component supply apparatus according to a first embodiment of the present invention. FIG. 2 shows a state in which the component supply device is applied to a winding device.

As shown in the figure, the component supply device includes a bowl-shaped (flapper-shaped) feeder 1. A bottom portion 1A of the feeder 1 is a component carry-in portion, and a plurality of cores 3 serve as components conveyed by a component supply device.
(Not shown in FIG. 2). The hopper 2 is a device that includes a core loading section 2A into which a large number of cores 3 are loaded, and drives the actuator 2B to tilt the core loading section 2A so that the core 3 flows into the feeder 1.

On the side near the bottom 1A of the feeder 1,
The suction port 1E is open. The suction port 1E is connected to an air passage 4 arranged on the side of the feeder 1 in a component introduction section 5 fixedly provided on the side of the feeder 1.

The air passage 4 is a passage extending from a compressed air source (not shown) through a component introduction section 5 to a component storage section 6 provided at the upper end of the feeder 1. It has an introduction path 4A and an air conveyance path 4B behind the component introduction section 5 also formed of an air hose.

A pressure regulator 7 and an ion generator 8 are interposed in the air introducing passage 4A. After the compressed air from the compressed air source is adjusted to an appropriate pressure by the pressure adjusting device 7, the compressed air is converted into air containing air ions by the ion generating device 7 and reaches the component introduction section 5. In the part introduction part 5,
At a low pressure generated by a high-speed air flow (air flow from the air introduction path 4A to the air conveyance path 4B), the core 3
Is sucked out. The core 5 sucked out in this manner is transported to the component storage section 6 through the air transport path 4B together with the compressed air flow.

Here, the ion generator 8 includes a static elimination electrode, a high-voltage power supply, and a high-voltage cable for connecting them, and applies an AC high voltage from the high-voltage power supply to the static elimination electrode to generate corona discharge. By doing so, positive and negative air ions are generated. When the core 3 is transported in the air transport path 4B, the core 3 comes into contact with the air flow containing the air ions to neutralize static electricity.

The component reservoir 6 is a container capable of accommodating a plurality of cores 3 and is connected to the start end of the component guide path 1B of the feeder 1. An air discharge unit 9 is provided immediately before (immediately above) the component storage unit 6 of the air passage 4. The air discharge section 9 has a plurality of air discharge holes 9A,
Compressed air is supplied to these air discharge holes 9 just before the component pool 6.
A is escaped from A, and the core 3 is swung down from the air discharge portion 9 into the component storage portion 6.

The component guide path 1B is a substantially circular rail-shaped groove formed along the upper edge of the feeder 1, and its rear end is connected to the component supply path 10. Parts pool 6
Is moved along the component guide path 1 </ b> B by the vibration of the feeder 1 by the vibration generator 12 controlled by the vibration controller 11. Then, as shown in FIG. 1, the feeder 1 makes a round around the upper edge of the feeder 1 and reaches the component supply path 10. The component supply path 10 is a substantially linear rail-shaped groove, and forms a component transport path together with the component guide path 1B.

A plurality of sorting members 1C are provided at important parts of the component guideway 1B (most of the sorting members 1C are not shown). This sorting member 1C
Is composed of a protruding portion protruding immediately above the component guide path 1B. If the core 3 is guided on the component guide path 1B in a correct posture, the core 3 passes directly below the sorting member 1C. On the other hand, if the posture of the core 3 guided on the component guide path 1B is not correct (for example, if the thing that should be lying down is in a standing state), the core 3
May be corrected to a correct posture by hitting the distribution member 1C, or may be shaken down from the notch 1D formed on the side of the component guide path 1B toward the inside of the feeder 1 to the bottom surface portion 1A of the feeder.

The core 3 guided to the component supply path 10 in this manner is moved by the vibration of the component supply path 9 by the vibration generator 14 controlled by the vibration controller 13 so that the component supply path 10
And is supplied to the core holding unit 20 of the winding device as a working device. Core holder 20 to which core 3 has been supplied
Is a winding unit 22,
Indexed on the front of various working units such as the welding unit 23, various operations are performed on the core 3.

Next, the operation will be described.

The plurality of cores 3 to be conveyed by the component supply device are first carried into the hopper 2, and are flowed into the bottom 1A of the feeder 1 by the operation of the hopper 2. In this state, when an air flow adjusted to an appropriate pressure is generated in the air passage 4 by the pressure adjusting device 7, the cores 3 in the feeder 1 are successively moved by the suction port 1 at a low pressure due to the air flow.
E sucks into the component introduction section 5 and is transported along with the compressed air through the air transport path 4B toward the component accumulation section 6.

In this case, the compressed air in the air passage 4 includes:
Positive and negative air ions are generated by an ion generator 8 provided between the pressure adjusting device 7 and the component introduction unit 5. For this reason, even if the core 3 sucked into the component introduction part 5 is charged with static electricity, this charge is removed (neutralized) by air ions contained in the compressed air. Therefore, the work of transporting the core 3 (for example, the posture correction and distribution work by the distribution member 1 </ b> C) is delayed by the charging of the core 3, or the various operations after the transportation (for example, the winding work) are performed by the charging of the core 3. It is possible to prevent troubles from occurring.

The core 3 guided to the component pool 6 is moved by the vibration of the feeder 1 to the component guide path 1 at the upper edge of the feeder 1.
It moves along B and is further guided through a component supply path 10 to a winding device, which is a working device, where various works are performed. In the component guide path 1B, the core 3 having an incorrect posture is corrected in posture or shaken down to the bottom surface 1A of the feeder 1 by the distribution member 1C.

As described above, the core 3 is sequentially conveyed from the bottom portion 1A of the feeder 1 on the air conveyance path 4B, the component guide path 1B, and the component supply path 10. In this case, the transfer operation from the bottom portion 1A of the feeder 1 to the upper edge (the component storage portion 6) is performed by compressed air through the air transfer path 4B, so that it can be performed extremely quickly and efficiently.

Further, due to the existence of the air conveyance path 4B,
The length of the component guide path 1B is sufficient for one circumference of the upper edge of the feeder 1. Therefore, the transport along the component guide path 1B does not have a long time, and the core 3
Can be less likely to be charged. Further, even if the core 3 is conveyed along the component guide path 1B without any front and rear gaps so that the cores 3 are successively supplied to the winding device, the total number of cores 3 required on the component guide path 1B is relatively small. I can do it.

The core 3 having an incorrect posture on the component guide path 1B may be corrected in posture by the distribution member 1C or may be shaken down into the feeder 1; 3 is the suction port 1 again
The air is sucked into the air passage 4 from E, and the charge is removed by air ions in the compressed air. By circulating the core 3 in this manner, the reliability of the charge removal of the core 3 is further enhanced.

FIG. 3 shows a second embodiment of the present invention.

As shown in the figure, the component supply device of the present embodiment includes a flat feeder 31. The planar feeder 31 is provided with a component guide path 31B which is a rail-shaped groove extending substantially linearly. This part guideway 31B
Is connected to the component reservoir 36, while the terminal end is a component supply unit 31F. The core 3 has a component storage portion 36.
Is introduced into the component guide path 31B, and the vibration generating device 42 controlled by the vibration control device 41 moves to the component supply portion 31F side by vibrating the planar feeder 31, and from the component supply portion 31F, It is supplied to the working device (winding device) side.

The component guide path 31B is provided with a distribution member 31C at a predetermined position, and a branch path 31G branches immediately after the distribution member 31B.
The distribution member 31C is a projection projecting above the component guide path 31B, and the core 3 introduced into the component guide path 31B from the component pool 36 passes below the distribution member 31C if the posture is correct. If the posture is not correct, it may hit the distribution member 31C and correct the posture,
It is pushed out to the branch road 31G side.

At a substantially middle of the branch path 31G, there is formed a component carrying portion 31H having a shape in which a groove is pushed out, and the core 3 is carried into the component carrying portion 31H from the hopper 2. The loaded core 3 and the core 3 sorted by the sorting member 31C are guided to the component introduction part 35 connected to the end of the branch path 31G by the vibration of the planar feeder 31 by the vibration generator 42.

The component introduction section 35 forms a part of the air passage 34, and the end of the air introduction path 34A, which also forms the air passage 34, and the start end of the air conveyance path 34B are connected to each other. The air introduction path 34A is connected to a compressed air source (not shown) at the start end, and has a pressure regulator 7 and an ion generator 8 interposed therebetween. As a result, the compressed air from the compressed air source is adjusted to an appropriate pressure by the pressure adjusting device 7, and further contains positive and negative air ions by the ion generator 8 and flows into the component introduction section 35. Then, the core 3 introduced (attracted) into the air passage 34 at a low pressure by the compressed air flow is transported together with the compressed air in the air transport path 34 </ b> B, and is transported to the component reservoir 36. Immediately before the component pool 36, an air discharge unit 39 having a plurality of air discharge holes 39A is provided.
Are provided, and compressed air is allowed to escape from these air discharge holes 39A.

With such a configuration, the component carry-in section 31H
Is transported in the air transport path 34B by an air flow containing positive and negative air ions, so that the charge is removed. Further, a part of the core 3 having an incorrect posture on the component guide path 31B circulates again to the air conveying path 34B side through the branch path 31G, and the reliability of the core 3 for removing static electricity is enhanced. In addition, the conveyance on the air conveyance path 34B is performed at an extremely high speed, and the part guide path 31B can be set to a relatively short distance by the air conveyance path 34B. Even if the cores 3 are transported one after another on the guide path 31B, the required total number of cores 3 is small. Therefore, the transfer operation of the core 3 is performed smoothly in an extremely short time, and the transfer operation can be made more efficient.
