Abstract

PURPOSE:To make wire rods possible to be separably taken out piece by piece irrespective of types and properties and so on, by shifting the wire rod to a separate drum, installing a wire rod storage part housing these wire rod out of the hopper provided with a V-groove. CONSTITUTION:A lot of wire rods 3 of the specified size are housed in a V- groove 4 of a hopper 1, and when a separate drum 2 is rotated and a wire rod storage part 7 faces to the V-groove 4 of the hopper 1, a motor 10 is stopped by an index device. And, if a vibrating member 5 is operated, the storage wire rods inside the hopper 1 collide with the drum 2, whereby a wire rod at a groove bottom of the V-groove 4 gets into the storage part 7. At this time, the storage part 7 is interconnected to a vacuum chamber 21, therefore suction force acts on the inside, and these wire rods 3 are smoothly housed in the storage part 7 as their tip is slightly projected from an outer circumferential surface of the drum 2 by dint of suction force owing to negative pressure in addition to dead load by a tilt of the V-groove 4 and vibrations in the vibrating member 5. Here, an opening part 7a of the storage part 7 is designed at be such a size that allows to pass one piece of these wire rods 3 but it fails to pass more than two pieces so that one piece only is surely fed therein.

Description

[Detailed Description of the Invention] [Prior Art] The present invention provides a wire separation device for separating and taking out thin wires cut into predetermined lengths one by one, such as lead wires, wires, etc. It is related to.

[Prior Art] Wire materials such as lead wires and wires are sometimes incorporated into electronic components, etc., but such wire materials are cut into a certain length in advance and stored in stock, and these wire materials are cut one by one. It is necessary to separate it, take it out, and assemble it into electronic components.

Methods for separating and taking out such wire rods include, for example, the sliding separation method in which the wire is separated from the hopper using a sliding means, and the magnetic separation method in which the wire is separated using the repulsive force or attraction force of a magnet in a magnetic stocker. However, depending on the separation method, it is not always possible to reliably separate one wire at a time, and the sliding separation method may not be able to separate wires one by one. When separating wire rods,
There is a risk of deformation, breakage, etc. occurring during separation, and the latter separation method is only effective for magnetic materials and cannot separate non-magnetic materials. Therefore, when it comes to wires such as lead wires that are relatively flexible and made of non-magnetic material, it is not possible to automatically separate them one by one and take them out, so one worker must manually separate them. Currently, we are trying to do this.

[Problem to be solved by the invention 1] Incidentally, in recent years, there has been a trend toward automation of assembly lines in order to mass produce electronic components at low cost. The inability to automate this has been a major hindrance in attempting to automatically assemble products such as electronic components.

The present invention has been made in view of the above points, and its purpose is to create a wire rod that can be reliably separated and taken out one by one, regardless of the type or properties of the wire rod. The purpose of the present invention is to provide a separation device.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention includes a hopper having grooves for accommodating a large number of wire rods, and a wire storage portion for storing the wire rods, which are bored in the radial direction. a separating drum, a rotary drive means for rotating the separating drum while indexing the separating drum to a position where the wire rod storage section thereof faces the groove of the hopper, and a wire rod transfer mechanism for transferring the wire rod from the hopper to the wire rod storage section. and the wire rod storage section is provided with a V of the hopper.
The wire rod is characterized in that the wire rod is separated one by one from the groove bottom of the hopper by the wire rod transfer mechanism in a state where the wire rod is positioned so as to face the groove, and the wire rod is stored in the wire rod storage section and taken out. It is something.

[Operation 1] A large number of wire rods are stored in the V-groove of the hopper, and the separation drum is rotated by a rotational drive means to position the wire rod storage section bored in the separation drum at a position facing the V-groove of the hopper. . Then, only one wire rod in the V-groove is transferred to the wire rod storage part of the separation drum by the wire rod transfer mechanism, and then the separation drum is rotated by a predetermined angle to discharge the wire rod in the wire rod storage part. It becomes possible to separate the wire rods from other books and take them out.

Here, the wire transfer mechanism uses the weight of the wire itself to slide the wire from the V-groove of the hopper into the wire storage portion of the separation drum.

It can be configured by arranging the hopper in an inclined state, and also by making the wire rod storage part negative pressure to suck the wire into the wire rod storage part, or by vibrating the hopper. can guide the wire. In order to quickly transfer the wire from the hopper to the wire storage section, it is preferable to adopt each of the above-mentioned configurations at the same time. The purpose can also be achieved by making the hopper vertical or by vibrating the hopper.

[Embodiment 1] Hereinafter, an uninvented embodiment will be described in detail based on the drawings.

First, in Fig. 1, 1 indicates a hopper, and 2 indicates a separation drum.As is clear from Fig. 2, hopper 1 is
A V-groove 4 is formed to accommodate a large number of wire rods 3 having a predetermined length. The hopper 1 is installed on a vibrating member 5 so that its V-groove 4 faces the center of the separating drum 2 at a predetermined angle, and the vibrating member 5 allows the hopper 1 to approach the separating drum 2.・It is designed to vibrate in the direction of separation. Further, a holding rod 6 is attached to the upper part of the V-groove 4 in order to prevent the wire rod 3 stored in the V-groove 4 from flying out during vibration of the hopper I.

On the other hand, six wire rod storage sections 7 are radially bored in the separation drum 2 at equal angular intervals from the inside toward the outer circumferential surface of the separation drum 2. The opening 7a has a size larger than the diameter of the wire 3 and smaller than twice this diameter, and the inside of the separation drum 2 forms a chamber 7b with a large cross-sectional area. The wire storage section 7 is configured to have a depth such that the wire 3 slightly protrudes outward from the outer peripheral surface of the separation drum 2 when the wire 3 is stored therein. has been done. and,
A rotating shaft 8 is connected to the separation drum 2, and a driven gear 8 is mounted on the rotating shaft 8. The driven gear 8 meshes with a driving gear 11 mounted on the output shaft of a motor 10. , whereby the separation drum 2 is configured to be rotationally driven by the motor 10. Further, an indexing means 12 is attached to the rotating shaft 8, and based on a signal from the indexing means 12, the motor 10 is turned on and off.
By performing the OFF control, the separation drum 2 can be rotated while being indexed at every predetermined angle.

The area around the separation drum 2 is divided into six work stations, and the part facing the hopper l is a separation stage electric which separates the wire rod 3. In this separation station, the opening of the wire storage section 7 of the separation drum 2 is separated. 7a is V groove 4 of hopper 1
The angle of the wire rod storage section 7 matches the inclination angle of the hopper 1 when facing the position near the bottom of the groove. A defective product detection station, a defective product discharge station, a wire rod detection station, a good product takeout station, and a takeout confirmation station are sequentially provided at 80° intervals from this separation station. Among these stages, defective product detection, wire rod detection and Each removal confirmation station is provided with detection members 13, 14, and 15 for detecting the protruding length of the wire 3 from the wire storage section 7, and the good item removal station is equipped with detection members 13, 14, and 15 for detecting the protruding length of the wire 3 from the wire storage section 7. A transfer means 18 for assembling is provided so as to face.

Furthermore, a communication passage 17 that opens on the side surface of the separation drum 2 is bored in the chamber part 7b of the wire storage section 7, and a circular ring is formed on the side surface on which the communication passage 17 is open. A housing 18 is attached, and the housing 18 is formed with high pressure chambers 19, 20 connected to a pressure source and negative pressure chambers 21, 22 connected to a negative pressure source. When the separation drum 2 rotates and the wire rod storage section 7 is at the wire separation station, it is communicated with a negative pressure chamber 21 for smoothly transferring the wire rod 3 from the hopper 1 to the wire rod storage section 7. When the wire storage section 7 is located at the defective product discharge station, it communicates with the high pressure chamber 19, and after passing through the defective product discharge station, the wire material 3 falls off from the wire detection station to just before the good product removal station. In order to prevent this from happening, the wire storage section 7 is placed in communication with the negative pressure chamber 22, and furthermore, at the good product removal station, the wire storage section 7 is communicated with the high pressure chamber 20.

Thus, the above-mentioned hopper 1 is vibrated by the vibrating member 5 in an inclined state, and the wire storage section 7 is located in the negative pressure chamber 2.
By communicating with 1, a wire transfer mechanism is constructed.

This embodiment is constructed as described above, and its operation will be explained next.

First, a large number of wire rods 3 cut to a predetermined length are stored in the V-groove 4 of the hopper 1, and the motor 10 is operated to rotate the separation drum 2 for one separation, and the wire rods are stored in the separation drum 2. When the part 7 comes to face the V-groove 4 of the hopper 1, the motor 10 is stopped by the indexing means 12. When the vibrating member 5 is operated in this state, the wire rod 3 stored in the hopper 1 is brought into contact with the separation drum 2, and is positioned at the bottom of the V-groove 4 as shown in FIG. The wire rod storage section 7 is made to carry the wire rods.

Here, since the wire storage section 7 communicates with the negative pressure chamber 21, a suction force acts inside it, and in addition to the own weight due to the inclination of the groove 4 and the vibration of the vibrating member 5, suction due to the negative pressure. Due to the force, the wire rod 3 is smoothly stored in the wire storage section 7 with its tip slightly protruding from the outer peripheral surface of the separation drum 2. Although 31 wire rods can pass through the opening 7a of the wire rod storage section 7, the dimensions are such that two or more wire rods 3 cannot pass therethrough.

This ensures that only one wire 3 is fed from the pallet. Moreover, the wire rods 3 are prevented from becoming entangled with each other due to the vibration of the vibrating member 5! Therefore, the transfer of the wire rod 3 to the wire rod storage section 7 is performed extremely smoothly.

After the transfer of the wire rod 3 into the wire rod storage section 7 is completed, the separation drum 2 is moved by operating the motor 10.
When the wire rod storage section 7 is rotated by 60'', the next wire rod storage section 7 faces the ■groove 4 of the hopper 1, and the wire rod storage section 7 is transferred from the hopper 1 to the wire rod storage section 7.
The wire rods 3 of the book are separated and stored, and the wire rod storage section 7 that has already stored the wire rods 3 is sent to a defective product detection station, and the detection member 1 installed at the defective product detection station
3, the protruding length of the wire 3 is detected.

Here, if the wire 3 is bent or is too long, it will not be stored in the wire storage part 7 to a predetermined position, and if the cut length of the wire 3 is insufficient, It is in a state where it does not protrude to a predetermined position. Therefore, by detecting the protruding length of the wire 3 from the outer peripheral surface of the separation drum 2, it is possible to detect whether the wire 3 is a good product or a defective product.

Furthermore, by rotating the separation drum 2 while indexing it by 60 degrees, the wire rods 3 are separated one by one from the hopper 1 while the separation drum 2 is stopped and stored in the wire rod storage section 7, and the wire rods 3 stored in this way are The defective product detection station detects defective products, and the defective product discharging station intermittently or continuously applies high pressure in the wire storage section 7 to blow out the defective products, and also detects the defective products at the wire detection station. The presence or absence of a good wire rod 3 is confirmed by the member 14, and the inside of the wire rod storage section 7 is intermittently or continuously made high pressure at the wire rod take-out station to blow out the good wire rod 3 and send it to the transfer means 18. , the wire rod 3 is separated into the drum 2
It will be taken out from. After that, at the unloading confirmation station, after confirming that the wire in the wire rod storage section 7 has been completely taken out, the wire rod storage section 7 returns to the wire separation station again, and the wire rod 3 is removed from the hopper 1.
Just take out the book. By repeating this process sequentially,
The wire rods 3 can now be separated and taken out one by one.

In the above-mentioned embodiment, the separation drum 2 is provided with six wire storage sections, but the number of wire storage sections may be set as appropriate depending on the number of work stations. Alternatively, wire rods of different lengths may be stored in the hopper I, and each work station may perform work such as sorting these wire rods according to their lengths. Further, in order to index the separation drum 2 at every predetermined angle, the motor 10 is turned on.
, OFF control is performed, however, a configuration may be adopted in which a clutch is connected to the motor 10 and indexing of the separation drum 2 is performed by connecting and disconnecting the clutch. Furthermore, the vibrating member 5 may be operated only while the separation drum 2 is stopped, or may be configured to be operated all the time. Furthermore, the hyperbaric chamber 19
, 20, if pressure is introduced intermittently, the wire can be smoothly blown out, but high pressure may be applied all the time. Furthermore, as a wire transfer mechanism,
Inclining the hopper 1, the vibration member 5, and the negative pressure chamber 2
1, but if the wire rod can be transferred reliably by one of these methods depending on the type of wire rod, the hopper can be arranged horizontally or the hopper can be held stationary. It is also possible to maintain the wire storage section at normal pressure.

[Effects of the Invention 1 As detailed above, the wire separation device according to the present invention has the following features:
■The wire rod is separated and taken out by transferring it from a hopper with grooves to a separating drum with a wire storage section perforated to store the wire rod, so with a simple configuration,
It becomes possible to reliably separate and take out wire rods one by one, regardless of their type or properties, such as thin wire diameter, flexible or fragile wire rods.
