Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to an improvement of a device for aligning parts that are easily deformed and have a large frictional force against slippage.

(Prior Art) As a device for aligning hard parts such as screws and nuts, a parts aligning device as shown in FIG. 7, for example, has conventionally been used.

A ring-shaped rotating part 3 in which a plurality of grooves 2 are formed radially is provided inside a cylindrical hopper 1 with an open front surface, and this rotating part 3 is connected to a motor 5 via a reducer 4. It is connected.

Furthermore, a shooter 6 is installed inside the ring-shaped rotating part 3.
is fixed, the upper end side of the shooter 6 is arranged close to the inner periphery of the upper groove 2 of the rotating part 3, and the lower end side of the shooter 6 is drawn out from the opening of the hopper 1.

In the parts aligning device having the above configuration, the hopper 1 is installed at an angle, and when parts 7 such as screws and nuts are thrown into the hopper 1, the parts 7 are fitted into the grooves 2 one by one while the rotating part 3 rotates. It gradually rotates and lifts upwards.

As they rotate to the upper side, they are inserted one by one into the upper part of the fixed shooter 6, slide down, and are arranged and guided outside.

However, in the conventional device, parts need to be smoothly fed from the concave groove 2 of the rotating part 3 to the fixed shooter 6, and although hard parts 7 such as screws and nuts are relatively good, things like O-rings etc. Components that are easily deformed and have a large frictional force against slippage have the disadvantage of being caught between the rotating part 3 and the fixed shooter 6, making it impossible to align them and damaging the components.

(Problems to be Solved by the Invention) The object of the present invention is to eliminate the above-mentioned drawbacks and provide a parts alignment device that can smoothly align even parts that are easily deformed and have a large frictional force against slippage. It is something.

[Structure of the idea]

(Means for Solving the Problems) The present invention includes a rotating part in which a groove is formed in the bottom of a hollow cylindrical hopper along the diameter direction, a rotational drive mechanism for rotating the rotating part in forward and reverse directions, and A cover that opens one end of the groove and closes the top, a passage hole that communicates with the other end of the groove and penetrates the side wall of the hopper, and a discharge that protrudes horizontally from the outer periphery of the side wall of the rotating part. A fixed part that rotatably supports the blade and the rotating part and has a ring-shaped guide groove in which the discharge blade slides, and a side wall of the fixed part is penetrated to connect the inner guide groove and the external shooter. It is characterized by consisting of a communicating discharge port.

(Function) In the parts alignment device of the present invention, when the hopper is installed at an angle and parts are thrown into the hopper, when the groove of the rotating part that rotates forward and backward rotates toward the bottom, the parts fall into the groove. As the rotating part enters the opening and reverses itself, it slides down the concave groove covered by the cover and is discharged from the passage port on the hopper side wall into the ring-shaped guide groove of the fixed part, and then from there to the discharge port. are arranged and discharged through an external shooter. Parts that are ejected from the passage port and stopped in the middle of the ring-shaped guide groove are pushed out to the ejection port by ejection vanes protruding from the outer periphery of the rotating part.

(Embodiment) An embodiment of the present invention will be described in detail below with reference to FIGS. 1 to 6.

In the figure, 8 is a rotating part, and 9 is a fixed part that rotatably supports the rotating part 8.

The rotating part 8 is provided with a hollow cylindrical hopper 10 at its upper part, and a lid 12 is attached to the upper part of the hopper 10, which is provided with a cylindrical inlet 11 whose upper part is diagonally cut out.

The hopper 10 has a concave groove 1 along the diameter direction.
3, and one end side of this groove 13 is tapered on both sides. A passage hole 15 is opened at the other end of the groove 13 through the side wall 14 of the hopper 10. Furthermore, a cover 16 in the form of a strip is attached above the groove 13 with the tapered portion open as shown in FIG. 4, and a passageway is formed between the cover 16 and the groove 13. 1
7 is formed, and the open part of the tapered concave groove 13 is used as the entrance port 18.

In addition, the outer circumference of Hopper 10 has a range of approximately 90 degrees.
A discharge blade 19 is provided to protrude horizontally.

Note that 20 is a cylindrical body provided within the hopper 10.

A ring-shaped guide groove 21 is formed between the ring-shaped fixed part 9 provided so as to surround the rotating part 8 and the outer periphery of the hopper 10, and the discharge blade 19 slides within this guide groove 21. I'm starting to do that. Further, a side wall 22 of the fixing portion 9 is partially cut out to form a discharge port 23, and a shutter 24 is provided externally adjacent to the discharge port 23.

The rotating part 8 is supported by a bearing 25 inside the fixed part 9, and a large-diameter gear 26A attached to the outer periphery of the rotary part 8 is rotated by meshing with a small-diameter gear 26B attached to the output shaft of the reducer 27. It's getting old.

Proximity switches 28A and 28B are installed symmetrically with an interval of 270 degrees, and when a stopper (not shown) of the rotating part 8 comes into contact with them, the motor 29 is rotated in the forward and reverse directions, and the rotating part 8 is rotated in the normal and reverse directions within a range of 270 degrees. It is designed to rotate in the opposite direction.

Next, the operation of the component alignment device having the above configuration will be explained.

First, insert the O-ring 30 from the input port 11 into the hopper 1.
0, the hopper 10 rotates while the O-ring 30 remains on the lower side of the hopper 10 because the hopper 10 is installed at an angle.

When the entry port 18 at the bottom of the hopper 10 reaches the lower side, one of the accumulated O-rings 30 is guided along the side surface of the cover 16, and the tapered groove 13 is guided as shown in FIG. It fits into the entrance 18 of the. When the rotating part 8 rotates 135 times on one side, a stopper (not shown) hits the proximity switch 28B and reverses, and when the entrance port 18 starts to rotate upward, the O-ring fitted in the entrance port 18 is removed as shown in FIG. 3
0 slides down the passageway 17 and is discharged into the guide groove 21 of the fixed part 9 through the passage opening 15 opened in the side wall 14 of the hopper 10.

Since the guide groove 21 is provided in an inclined manner, the O-ring 30 guided therein slides on the guide groove 21 and is discharged to the external shutter 24 from the discharge port 23 provided at the lower part.

When the ring 30 comes to a stop in the middle of the guide groove 21, it is pushed out to the discharge port 23 by the discharge vane 19 which rotates in forward and reverse directions within a range of 270 degrees.

In this way, each time the rotating part 9 rotates forward and backward, the O-rings 30 fitted in the inlet 18 are aligned one by one in the passage 17 of the rotating part 8 and guided to the guide groove 21 on the fixed part 9 side. Slide down from here and exit port 2
3 are discharged one by one and arranged in a shutter 24.

In the above embodiment, the range in which the rotating part rotates forward and backward is 270 degrees, but the range can be arbitrarily selected.

[Effect of idea]

As explained above, according to the present invention, unlike the conventional structure in which parts are aligned one by one when being supplied from the rotating part to the fixed part, parts are removed one by one within the rotating part and aligned within the rotating part. There is no deformation or damage due to parts being caught, making it suitable for aligning easily deformable parts such as rubber products.Moreover, the parts ejected into the guide groove are forcibly pushed out by the ejection vane, so there is no friction against slipping. A component alignment device that can smoothly align even components that are subjected to large forces can be obtained.
