Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a component supply device used in the manufacturing process of electronic components.

(Prior Art) Generally, a cathode for a cathode ray tube is made by inserting a cathode tube 11, which is a component, into a support 12 and then welding the two together, as shown in FIG. The cathode tube 11 is a component in which one end of the cylinder body 11a is closed with a disk 11b, and in which combination of the supports 12, it is necessary to supply the cathode tube 11 sequentially while maintaining the direction such that the disk 11b always faces upward. There is. For this purpose,
A large number of cathode tubes 11 are connected to their disks 11b.
They must be aligned so that they all face the same direction and their axes are parallel to each other.

Conventionally, this type of parts supply has been carried out using, for example, a pole feeder 14 and a chute 15 connected to its delivery section, as shown in FIG.

That is, a large number of parts 11 housed in the pole feeder 14 are moved along the inner periphery by vibration while being aligned in series along the axial direction. Then, using the step 16 provided at the delivery section of the pole feeder 14, the component 11 is stood up as shown in FIG. The component 11 erected in this way moves in parallel as it is and enters the chute 15. Then, the linear feeder 1 shown in FIG.
The vibrations of the chute 15 cause the sheets to rotate along the outer circumferential direction of the chute 15, and the twisting of the chute 15 gradually changes the direction in a predetermined direction, and the sheets are sequentially supplied in a horizontally aligned state.

(Problems to be Solved by the Invention) The component 11 is a cylinder body 11a made by cutting a cylinder material into a predetermined length, and a disk 11b welded around the entire circumference to the end of the cylinder body 11a.
Due to errors during cutting, the quality of the cylindrical body 11a varies, and the position of the center of gravity of the disk 11b after welding changes. For this reason, when the steps 16 are used to stand the objects at the exit of the pole feeder 14, even if the vibration is adjusted, many objects cannot stand due to the variation in the center of gravity and end up inside the pole feeder 14. Also, even if you stand up, you may fall down before entering chute 15, or you may fall down before entering chute 1.
Many fall within 5. Further, the delivery speed by the chute 15 is slow, making it impossible to improve the supply capacity.

Furthermore, the orientation of the parts 11, that is, the sorting between those with the disk 11b and those without the disk 11b, is not performed reliably, which may cause trouble to the processing machine.

The purpose of the present invention is to be able to reliably sort the orientation of parts and eliminate problems with processing machines associated with parts supply, and to increase the supply speed and accurately align the parts.
An object of the present invention is to provide a parts supply device that improves the operating rate of equipment.

[Structure of the invention]

(Means for Solving Problem No. 121) A component supply device according to the present invention has a rotary having a disc shape and whose axis is disposed laterally.

A plurality of component holding grooves are formed on the outer periphery of the rotary hole at equal intervals in the outer periphery direction. The rotary is provided with a first chute for moving the component along its axis. The first chute is disposed such that the delivery end of the component communicates linearly with a holding groove located at the top of the outer periphery of the rotary. Further, the rotary is driven to rotate by an angle corresponding to the mutual spacing between the plurality of holding grooves by the driving device. Further, the outer periphery of the rotary from the position of the holding groove for receiving parts at the top of the outer periphery of the rotary to the position of the holding groove for sending out parts at the lower part of the outer periphery is covered by the holder.

Furthermore, a direction determination sensor Gj is provided at a position opposite to the holding groove holding the component, and is configured to determine the direction of the component held in the holding groove. Further, a removing device is provided to remove the component whose orientation is determined to be defective by the direction determination sensor from the holding groove. Further, a second chute is provided for moving the component sent out from the holding groove located at the holding groove position for sending out the component in parallel in a direction orthogonal to the axial direction of the part.

(Function) In the present invention, the first chute moves the component along its axial direction and feeds it into the holding groove formed on the outer periphery of the rotary. The 0-crystal receives the parts one by one into the plurality of holding grooves by rotating at predetermined angles. A direction determination sensor determines whether the component in the holding groove is held in a predetermined direction.

As a result, those determined to be in a defective direction are removed from the holding groove by a removal device. Those that are determined to be in the correct direction are sent as they are to the holding groove position for delivery, and from there they are transferred to the second
sent out to the chute. The second chute translates the part in a direction perpendicular to its axis. Through this series of operations, a large number of parts are aligned while maintaining a predetermined direction,
Supply sequentially.

(Example) Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, reference numeral 18 denotes a first sheet, which moves the parts 11 fed in series along the axial direction by a pole feeder (not shown) along the axial direction. . The movement of the component 11 within the first chute 18 is carried out by the vibration of the near feeder 20, as shown in FIG. Part 1
No obstacles such as falling will occur during the progress of step 1. For this reason, the vibration frequency of the linear feeder 20 can be increased, and as a result, the moving speed of the component 11 in the chute 18 of the feeder 1 becomes faster.

21 is a rotary, which has a disc shape as shown in Fig. 3;
A plurality of holding grooves 22 for holding the component 11 are provided on the outer periphery at equal intervals in the outer circumferential direction.

The rotary 21 is arranged so that its axis, that is, the shaft 23 is oriented laterally, and the shaft 23 is rotatably supported by a bearing 25 provided on a fixture 24.

Here, a retaining groove 2 located at the top of the outer circumference of the rotary 21
Components 11 are fed into 2 from the first chute 18. For this reason, the first chute 18 is arranged such that the delivery end 18a shown in FIG. 2 communicates linearly with the holding groove 22 located at the top of the outer periphery. Therefore, as shown in FIG. 4, the holding groove position 22A at the top of the outer circumference of the rotary 21 is a position for receiving the component 11.

On the other hand, the holding groove position 22B at the lower part of the outer periphery is a part delivery position where the part 11 is dropped.

A driving device 27 includes a stepping motor 28, a timing pulley 29 directly connected to its rotating shaft, and a timing bell l stretched between the timing pulley 29 and a timing pulley 30 directly connected to the shaft 23 of the rotary 21. ~31. This drive device 27 rotates the rotary 21 via a timing belt 31 by the rotation of a stepping motor 28, and moves the rotary 21 at intervals between the respective retaining grooves 22 provided on the outer periphery of the rotary 21.

Rotate by the corresponding angle.

A holder 33 is provided so as to cover the outer periphery of the rotary 21. Note that, as shown in FIG. 3, the parts corresponding to the holding groove position 22A for receiving parts and the holding groove position 22B for sending out parts shown in FIG. 4 are provided with notches 33a.

33b is provided to enable receiving and sending out the parts 11. This holder 33 is for preventing the component 11 held in the holding groove 22 from falling due to the rotation of the rotary 21, and the outer peripheral surface of the rotary 21 is
In order to allow the movement of the component 11 held at 2, a predetermined holding interval is maintained. Further, since the component 11 is not held in the holding groove 22 corresponding to the component in the right half of FIG. 3, the component in the right half of the holder 33 may be omitted.

A component confirmation sensor 34 detects whether or not the component 11 is present in the holding groove 22 located at the component receiving position 22A shown in FIG. As shown in FIG. 5, this sensor 34 is a transmission type optical fiber sensor consisting of a light emitting side 34a and a light receiving side 34b. emits a ray of light. The light receiving side 34b directs this light beam to the holder 33.
The light is received through the through hole 33c provided in the bottom plate of the sensor 34. Of course, if the component 11 exists in the holding groove 22, the light beam is blocked and the light receiving side 34b does not receive this light beam. When the light-receiving side 34b does not receive the light beam, it is determined that there is a component in the holding part 22, and based on the determination result, the driving device 27 is operated and the rotary 21 is rotated at the predetermined angle described above.

Reference numeral 35 denotes a cover that covers the outer peripheral edge of the rotary 21 in an area corresponding to the left half of the holder 33 shown in FIG. prevent.

Here, for the component 11 held in the holding groove 22, it is checked whether the position of the disk 11b is facing in the correct direction. Let's do it. As shown in FIG. 6, a through hole 35a and a through hole 33d are provided in the bottom plate of the cover 35 and the holder 33 at positions facing the checking holding groove position 22C, respectively.

A direction determination sensor 37 faces the holding groove 22 at the checking position 22C through the through hole 35a, and determines the direction of the component 11 held in the holding groove 22. As this direction discrimination sensor 37, a limited reflection type optical fiber sensor is used. This sensor 31 detects ff1M
If the disk 11b of the component 11 is at the right end position in FIG. 6, the projected light will be reflected, and by receiving this reflected light, it is determined that the disk 11b is at the right end position.

On the other hand, when the disk 11b is at the left end position, the projected light is not reflected, so it is determined that the component 11 is oriented in the opposite direction to the above case.

38 is a parts removal device, which includes an air nozzle 38 for parts removal.
a, and a chute 38b for removing parts. The air nozzle 38a faces the through hole 33d provided in the holder 33, and blows away the component 11 determined to be in the defective direction by the direction discrimination sensor 37 from the holding groove 22, and discharges it through a chute 38b provided on the opposite side. .

A second chute 40 is provided below the rotary 21 along a direction perpendicular to its axis, and receives the component 11 that has fallen from the holder v422 located at the component delivery position 22B in FIG. 41 is an air nozzle for moving parts,
The parts 11 which are provided on the second chute 40 and have fallen from the holding groove 22 of the rotary 21 are moved in parallel on the second chute 40. 42 is a sensor for detecting the presence or absence of parts on the chute, which detects when the parts 11 are lined up on the chute 40 and stops the rotation of the rotary 21.

In the above configuration, the component 11 fed from a pole feeder (not shown) is conveyed by the first chute 18 along its axial direction, and is fed into the holding groove 22 at the component receiving position 22A of the rotary chest 21. . Holding groove 2
When the part 11 is fed into the rotary part 2, the part confirmation sensor 34 detects this, and the drive device 27 is operated to rotate the rotary 21 by a predetermined angle. This rotation causes the next empty holding groove 22 to reach the component receiving position 22^, so that the component 11 is also fed into this holding groove 22 from the first chute 18. In this manner, each time the rotary 21 rotates, the components 11 are sequentially fed into the holding groove 22 located at the component receiving position 22A.

The direction of the component 11 held in the holding groove 22 is checked by the direction determination sensor 37 at the checking position 22C in FIG. As a result, if the direction is opposite to the normal direction, it is determined to be a defective direction, and the component removing device 38 is operated, thereby removing the component 11 from the holding groove 22. Also, if it is in the normal direction, hold W4 as it is.
22, and falls from the holding groove 22 at a part delivery position 22B in FIG. The component 11 that has fallen from this holding groove 22 enters the second chute 40 and enters the air nozzle 41.
is driven in a direction perpendicular to the axis.

As a result, the parts 11 are aligned so that their axes are parallel to each other with the disks 11b facing in a certain direction, and are fed from the second chute 40. Therefore, parts 11 in different directions are not supplied, and troubles in the processing machine caused by parts supply can be reliably prevented.

Furthermore, the feeding speed of the parts 11 by the first chute 18 and the second chute 40 is also higher than that of the conventional system, improving the supply capacity and improving the operating rate of the equipment.

〔Effect of the invention〕

As described above, according to the present invention, parts can be sequentially fed while reliably maintaining a predetermined directionality, and troubles on the processing machine side associated with parts feeding can be eliminated. It will also improve parts supply capacity and improve equipment operating rates.
