Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an O-ring, a washer, a nut and the like (hereinafter referred to as an O-ring) suitable for aligning and transporting parts having a substantially circular shape. The present invention relates to an alignment conveyance device.

[0002]

2. Description of the Related Art Conventionally, as a device of this type, there is known a technique in which a grooved blade is vertically swung in a hopper to align O-rings and the like.

[0003]

DISCLOSURE OF THE INVENTION In this device,
When using a cylinder, reciprocating motion must be converted into oscillating motion, and when using a motor, transmission gears must be used, which requires a large space and increases the cost of the device. There are problems such as sticking.

Accordingly, it is an object of the present invention to reduce the cost of the apparatus by downsizing the aligning and conveying apparatus such as an O-ring.

Another object is to prevent the blade from moving up and down more than necessary in order to save power, prevent noise, and prevent wear of the device.

A further object is to automatically convey the O-rings and the like housed in the hopper without leaving them in the hopper.

[0007]

[Means for Solving the Problems] (1) A large number of O-rings and the like are accommodated in a blade having an inclined surface formed in an upper groove so that the O-rings and the like in the hopper rotate or slide under its own weight. It is provided vertically in the hopper to be vertically movable.

(2) A sensor for detecting the presence / absence of a specific amount of the O-ring or the like is provided in order to stop or start the vertical movement of the blade when the O-ring or the like is conveyed in a specific amount.

(3) In order to align the O-rings and the like housed in the hopper without leaving them in the hopper, in the hopper, the upper part is oriented toward the blade with the same inclination (7a) as the inclined surface (3d) of the blade. And a pedestal for receiving an O-ring or the like formed with a slope (7b) that inclines low.

[0010]

[Action]

(1) In the hopper, a large number of O-rings and the like having the same shape are housed in a disordered state, and when the blade moves upward, the O-rings and the like are formed on the slopes in the grooves provided on the blade. It rotates or slides under its own weight and moves toward the opening of the hopper, and is aligned and conveyed to the conveyance path outside the hopper.

At this time, the O-ring located at the lowermost part of the groove on the inclined surface of the blade moves upward while sliding on the inner surface of the hopper.

(2) When the O-ring and the like are aligned and conveyed to a specific amount, the blade does not need to move up and down, so a sensor that detects the presence or absence of the O-ring operates to stop the blade from moving up and down. Further, when the O-rings or the like are aligned and conveyed below a specific amount, the blades need to move up and down. Therefore, a sensor for detecting the presence or absence of the O-rings operates and the blades move up and down.

(3) Since the O-rings and the like housed in the hopper are automatically aligned and conveyed without being left in the hopper,
Inside the hopper, the slope (7a) which is approximately the same as the slope (3d) of the blade and the slope (7
b) is provided, and when the remaining amount of the O-ring etc. in the hopper becomes small, the O-ring etc. slides on the slope of the pedestal by its own weight and is placed on the slope in the groove of the blade. It is moved up with the blade and aligned and conveyed.

【The invention's effect】

(1) As described above, a blade having a bevel in the groove is vertically movably provided in a hopper that accommodates a large number of O-rings and the like, and when the blade moves upward, the blade is provided in the groove. Since the O-ring etc. rotates or slides on the inclined surface of the hopper by its own weight and moves toward the opening of the hopper and is aligned and transported to the transport path outside the hopper, the device can be downsized and the equipment cost can be reduced. It has become possible to provide a low-priced O-ring alignment transport device.

(2) When the O-rings and the like are aligned and carried to the carrying path to a specified amount, the blade does not need to move up and down.
The sensor that detects the presence or absence of O-rings stops the blades from moving up and down, and when the O-rings and the like are aligned and conveyed below a specified amount, the blades need to move up and down. Since the sensor that detects is activated and the blade is configured to move up and down, it is possible to minimize the up and down movement of the cylinder shaft, which saves power.
It is possible to prevent noise and prevent wear of the device.

(3) Inside the hopper, there is provided a pedestal having an inclined surface (7a) substantially the same as the inclined surface (3d) of the blade and an inclined surface (7b) inclined downward toward the blade.
When the remaining amount of O-rings etc. in the hopper becomes small, the O-rings etc. slide on the slope of the pedestal by their own weight and are placed on the slope of the groove of the blade and moved up with the blade to be conveyed in an aligned manner. The O-rings and the like housed in are automatically aligned and conveyed without remaining in the hopper.

Due to the above-mentioned effects, this device can be optimally applied to automatic mounting on other parts such as shafts and screws.
