Description

Detailed Description of the Invention

The present invention relates to spring separators. More specifically, the present invention relates to a spring separator capable of preventing entanglement of springs and reliably separating the springs.

2. Description of the Related Art A vibrator type parts feeder has been used as a device for supplying various springs such as a regulator spring, a brush holding spring for a commutator motor, and a pressure valve spring. The parts feeder is adapted to transmit the vibration generated by the rotor (pulsator) to the drum arranged in the central part of the device. Then, by utilizing this vibration, the springs supplied onto the drum are sequentially aligned and moved on the spirally formed passage on the outer peripheral portion of the drum.

[0003]

However, in the above-mentioned conventional vibrator-type device, the separation efficiency is very small at 50% or less because the springs are entangled with each other, which hinders the subsequent work.

In view of the above circumstances, it is an object of the present invention to provide a spring separator capable of reliably separating the spring and supplying it to the next step.

SUMMARY OF THE INVENTION A spring separator according to the present invention comprises: (a) a substantially cylindrical basket containing a spring to be separated and having at least one opening formed near one end thereof. , (B) located in the basket,
A rotary plate on the surface of which at least one flip-up pin is formed; (c) rotating means connected to the rotary plate for giving intermittent rotation to the rotary plate; and (d) along the outer peripheral surface of the basket. And a chute that communicates with the opening formed in the basket and has an outlet at one end, and (e) is provided at the opening-side end of the basket, and has a female screw portion formed in the center. An upper cover, and (f) a substantially umbrella-shaped separating plate including a male screw part to be screwed with a female screw part of the upper cover and a head having an inclined surface, wherein the separating plate is the separating plate. The separating plate is screwed onto the upper lid so that the inclined surface of the is located in the basket.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A spring separator according to the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a partially cutaway view of an embodiment of a spring separator of the present invention, FIG. 2 is a schematic perspective view of the basket shown in FIG. 1, and FIG. 3 is a front view of a separator.

In FIG. 1, reference numeral 1 is a substantially cylindrical basket in which a spring S is housed. Basket 1
Is acrylic, so that the inside can be observed from the outside.
It is preferably made of a transparent synthetic resin such as polypropylene. The basket 1 is mounted on a base 2, and a motor, a controller for controlling the movement of the motor, and the like, which are not shown, are housed in the base 2. An opening 3 for discharging a spring is formed near one end of the basket 1 (an end opposite to the base 2), as shown in FIG. The number of these openings 3,
The shape, position and size may be appropriately selected according to the type and size of the spring to be separated, and are not particularly limited in the present invention. If the opening 3 is too large, the number of springs S supplied at one time becomes too large, which may cause entanglement. On the other hand, if the opening 3 is too small, the spring S may not be supplied as expected.

Inside the basket 1, a rotating plate 4 for pushing up the spring S is arranged on the side opposite to the side where the opening 3 is formed. At least one flip-up pin 5 is formed on the surface of the rotary plate 4. The preferred number of the splashing pins 5 is usually about 4 to 7,
These pins 5 are preferably arranged evenly around the rotary plate 4 (see FIG. 1). The splashing pin 5 is preferably made of SK3 hardened steel or the like in consideration of wear resistance and durability. The size of the flip-up pin 5 differs depending on the type and size of the spring S to be separated, but normally the diameter is 5 to 6
mm, height 2-4 mm.

Reference numeral 6 denotes a shaft of a motor, which is a rotating means, arranged in the base 2, and the motor provides intermittent rotation to the rotary plate 4. The rotation speed is as a motor
It is possible to use a speed of 5,000 to 10,000 rpm,
The rotation time for one rotation varies depending on the type and size of the spring, but is usually about 1 to 2 seconds. This rotation time is base 2
It can be appropriately adjusted by a controller provided therein.

The rotating plate 4 may be rotated only in one direction, but if the rotating plate 4 is rotated alternately in forward and reverse directions, the separation of the spring is further promoted.

Outside the basket 1, the basket 1
A chute 7 is provided along the outer peripheral surface of the. The chute 7 communicates with the opening 3 formed in the basket 1 and has a separate outlet 8 for the spring S at one end. The spring S pushed up by the rotation of the rotary plate 4 and passed through the opening 3 of the basket 1 slides in the chute 7 and falls from the outlet 8 onto the saucer 9 formed on the base 2. The worker picks up the spring S that has fallen on the tray 9 and performs a predetermined assembly work.

Reference numeral 10 denotes an upper lid provided at the end of the basket 1 on the opening 3 side, and a female screw portion is formed at the center of the upper lid 10. The male screw portion 12 of the substantially umbrella-shaped separating plate 11 shown in FIG. 3 is screwed into the female screw portion. The separating plate 11 is composed of this male screw portion 12 and a head portion 14 having an inclined surface 13. The separating plate 11 is screwed to the upper lid 10 so that the inclined surface 13 is located in the basket 1. There is. The inclined surface 13 of the separating plate 11 is, as shown in FIG.
It has a function of reflecting the spring S pushed up by the rotation of and causing the spring S to jump into the opening 3. The angle θ (see FIG. 3) of the inclined surface 13 is selected in consideration of the position and the like of the opening 3 in consideration of such a function, but normally 5 to 5 is selected.
It is selected within the range of 20 °.

[0014]

As described above, according to the spring separator of the present invention, the spring is separated by the push-up action of the pin formed on the surface of the rotary plate. Therefore, the spring can be separated surely. You can Further, the pace of supply of the spring can be arbitrarily set by appropriately selecting the rotation time of the rotating plate once.
