Abstract

PURPOSE:To eliminate damage of parts and to smoothly take out the parts by inverting a part storage case until the parts therein becomes horizontal, and by pressing the casing against a part feeder through the intermediary of a resilient member. CONSTITUTION:A storage casing A stored therein parts 2 is conveyed from a casing feed device A to a casing discharge plate 26. The casing 4 is secured to a holder 2 and a holder 20 for a casing turning arm 18. Then, the casing turning arm 18 is rotated by an angle of 90 deg. so as to be made into contact with a resilient member 32 on the bottom part of a part feed container 30. Thereby the parts 2 stored in the casing 4 becomes substantially horizontal. Due to the contact with the resilient member 32, vibration is transmitted from a linear feeder to the casing 4 through the resilient member 32 so that the parts 2 in the casing 4 are fed into a part supply section 30 with the attitudes of the parts 2 being unchanged. With this arrangement, it is possible to smoothly supply the parts without the attitudes thereof being altered, thereby it is possible to prevent the parts from being damaged.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a case for taking out a large number of needle-shaped parts housed in a case facing in a certain direction without changing their orientation. This invention relates to a device for taking out stored needle-shaped parts.

[Conventional technology]

When a parts feeder is used to feed needle-like parts in an aligned manner, while the needle-like parts circulate in the bowl of the parts feeder, they may fall from the upper stage of the bowl or be damaged or deformed due to contact between parts. Sometimes.

The present inventor has developed a device that aligns needle-like parts while conveying them in a fixed direction using a vibration effect without using a parts feeder. In this device, one method of feeding needle-like parts to the parts supply feeder is to house a large number of needle-like parts in a case facing in a certain direction, and then take out the needle-like parts from inside the case by vibration action. .

A device having the configuration shown in FIG. 8 can be considered as an apparatus for carrying out this extraction method. A case rotation arm 54 that rotates in a vertical plane is provided on the front side of a component supply container 520 attached to a linear feeder, and a case 58 containing a large number of needle-like components 56 facing a certain direction is attached to the case rotation arm 54. The case rotating arm 54 is rotated by 90° or more from the horizontal position to allow the needle-shaped component 56 housed in the case 58 to slide down and be supplied to the component supply container 52.

[Problem that the invention seeks to solve]

The needle-like component retrieval device having such a configuration has a needle-like component 5.
When the needle-shaped part 6 slides out of the case 58 in the forward position, a part of it may be reversed and the transport position may be reversed (the needle-like part 56
(The shorter the needle, the easier it is to be reversed.) This makes it impossible to align and feed the needle-like parts.

In view of these problems, the present invention has been made for the purpose of removing a large number of needle-shaped parts housed in a case facing a certain direction without changing their posture due to the vibration effect. It is.

[Means for solving problems]

The first invention is to provide a case inversion arm that rotates in a vertical plane on the front side of a parts supply feeder, and to invert the case with a holder for holding a case containing a large number of needle-like parts facing in a certain direction. The case containing the needle-like component is mounted on the arm and rotated approximately 90 degrees toward the component supply feeder until the case-reversing arm is rotated approximately 90 degrees toward the component supply feeder until the needle-like component housed in the case becomes almost horizontal. The device is characterized in that it is configured so as to come into contact with the parts supply feeder.

In addition, the second invention transmits minute vibrations to the case reversing arm and rotates the case reversing arm approximately 90'' toward the component supply feeder until the needle-shaped component housed in the case becomes almost horizontal. The present invention is characterized in that the case containing the needle-shaped component and the component supply feeder are configured to be in non-contact with each other in the posture.

[Action of the invention]

In the first invention, when the case rotating arm is rotated approximately 909 degrees toward the component supply feeder, the needle-like component housed in the case becomes almost horizontal, and the case is rotated through the elastic body to the component supply feeder. The vibrations of the parts supply feeder are transmitted to the case in which the needle-like parts are housed through the elastic body. The needle-like parts housed in the case are in a nearly horizontal position, and the vibrations of the parts supply feeder are transmitted to the case through the elastic body, so the vibrations are damped, so the needle-like parts are not turned over. It is smoothly removed from the case in almost the same horizontal position.

In the second invention, even if the case rotation arm is rotated approximately 90 degrees toward the component supply feeder and the needle-like component housed in the case is in a nearly horizontal position, the case and the component supply feeder are not in contact with each other. The slight vibration of the case rotation arm is transmitted to the case housing the needle-like parts.
Due to this vibration action, the needle-shaped part inside the case is not turned over (it is smoothly taken out in a horizontal position as it is).

〔Example〕

An embodiment of the first invention is shown in FIGS. 1 to 6. It should be noted that the needle-like component in this embodiment has a head.

A cylindrical case 4 containing a large number of needle-like components 2 with the head facing upward is transferred from a case supply device A to a needle-like component extraction device B.
is supplied to

The case supply device A includes a rotating disk 6 whose outer periphery is covered with a transparent cover 8, and a 0-rotation disk 6 that is stocked by placing a large number of cases 4 containing needle-shaped parts 2 on the rotating disk 6. When rotates in the direction of arrow P, case 4
hits a guide plate 10 fixed directly above the rotating disk 6, and by the rotating action of the rotating disk 6, the case 4 is sent along the guide plate 10 to the outer periphery of the rotating disk 6, and is placed on a case discharge plate 26, which will be described later. be transported.

The needle-like component extractor B takes out a large number of needle-like components 2 housed in the case 4 transferred from the case supply device A and supplies them to the component supply feeder C.

The needle-like component removal device MB has a motor 1 attached to the side plate 12.
A pair of holders 20 and 22 for holding the case 4 in which the base end of a case rotation arm 180 is fixed to the drive shaft 16 of the case rotation arm 18 and the needle-shaped component 2 is accommodated on the side surface of the case rotation arm 18.
is installed. The retainer 20 is fixed to the case rotation arm 18, while the retainer 22 rotates about a horizontal axis under the action of a solenoid 24 mounted on the opposite side of the case rotation arm 18. Due to the rotation of the motor 14, the case rotating arm 18 reciprocates within a vertical plane around the drive shaft 16 of the motor 14 as a fulcrum within a rotation angle range of approximately 90'' between the horizontal position and the vertical position. 18 is provided on the front side of the supply section of the component supply feeder C.

A case discharge plate 26 is provided horizontally in front of the supply section of the component supply feeder C, and this case discharge plate 26 is rotated by the action of a case discharge plate rotation motor 28 attached to the side plate 12. The case discharge plate 26 is disposed between the case rotating arm 18 in a horizontal position and the rotating disk 6,
Its height is equal to the height of the rotating disk 6.

The component supply feeder C has a component supply container 30 attached to a linear feeder and conveys the needle-like components 2 by vibration. An elastic body 3 such as a rubber plate is placed on the inner bottom of the part.
2 is installed.

When the case 4 containing the needle-like parts 2 is transferred from the case supply device A to the case discharge plate 26 which is waiting horizontally,
Case detection sensor 34 attached to case rotation arm 18
detects this, and a solenoid 24 attached to the case rotation arm 18 is activated. The holder 22 is rotated by the operation of the solenoid 24, and the case 4 is held by this holder 22 and the holder 20 fixed to the case rotation arm 18.

In this state, when the case rotation arm 18 is rotated approximately 90 degrees by the motor 14 attached to the side plate 12, it is attached to the inner bottom of the supply section of the component supply container 30, as shown in FIGS. 2 and 5. The case 4 comes into contact with the elastic body 32, and the posture of the needle-shaped component 2 housed in the case 4 becomes almost horizontal. When the case 4 comes into contact with the elastic body 32, the vibration of the linear feeder L is attenuated and transmitted to the case 4 via the elastic body 32, and this vibration action causes the needle-like component 2 housed in the case 4 in a substantially horizontal posture to is smoothly taken out from the case 4 in almost the same posture without being turned over, and is supplied to the component supply container 30.

Note that instead of attaching the elastic body 32 to the component supply container 30 as in this embodiment, it is also possible to attach an annular elastic body to the outer periphery of the case 4.

When the needle-shaped part 2 inside the case 4 is completely taken out, the motor 14 is activated and the case rotating arm 18 rotates in the opposite direction to the above-described direction and returns to its original position to become horizontal.

When the case rotation arm 18 returns to its original position, the solenoid 2
4, the holder 20 rotates to release the empty case 4 and place it on the case discharge plate 26. Side plate 12
When the case ejection plate 26 is rotated downward by a case ejection plate rotation motor 28 attached to the case ejection plate, the empty case 4 falls and is ejected using the ejection shade 36. After ejecting the empty case 4, the case ejection plate 26 returns to its original position.

When the residual amount detection sensor 38 attached to the parts supply container 30 detects that there is no needle-like component 2 housed in the container 30, the rotating disk 6 rotates again in the direction of arrow P to close the case. The case 4 containing the needle-like component 2 is transferred from the supply device A to the needle-like component removal device B, and the above-described operation is repeated.

An embodiment of the second invention is shown in FIG. 7, and the same parts as in the embodiment of the first invention described above will be described with the same reference numerals.

The case 4 containing the needle-like component 2 and the component supply container are placed in a component removal position in which the case rotation arm 18 is rotated toward the component supply container 30 until the needle-like component 2 accommodated in the case 4 becomes almost horizontal. No contact with 30,
The vibrations of the linear feeder L are attenuated and transmitted to the case 4 via the side plate 12 and the case rotation arm 18, and due to this vibration action, the needle-like component 2, which is housed in the case 4 in a substantially horizontal position, remains in substantially the same position. It can be taken out smoothly without turning over.

Note that 40 in the figure indicates a chute connected to the component supply container 30.

〔Effect of the invention〕

By rotating the case rotation arm and positioning it almost vertically, the present invention brings a large number of needle-like parts housed in the case in a horizontal position facing a certain direction, and in this position, the case vibrates slightly. The structure is such that the needle-like parts housed in the case are taken out by the vibration effect, so the many needle-like parts housed in the case can be taken out smoothly in almost the same horizontal position without being turned over. . Therefore, it becomes possible to supply the needle-like parts in an aligned manner.
