Description

[Detailed Description of the Invention] A. Purpose of the Invention a. Field of Industrial Application The present invention relates to a device that automatically aligns and conveys short cylindrical objects.

b. Prior Art Conventionally, vibrating automatic alignment and conveyance devices have generally been used to feed short cylindrical objects made of metal or plastic to press machines, molding machines, or other processing machines while aligning them. ing. This is also called a parts feeder, and is a large-diameter dish-shaped container with a spiral passage toward the top of the outer periphery.
The container is made to vibrate finely using a spring. Due to this vibration, the short cylindrical objects in the center gradually move forward along the path, and only those aligned laterally reach the upper part of the outer periphery.
It is transported to processing machines, etc.

c. Problems to be solved by the invention Although the conventional vibrating type automatic alignment and conveyance device as described above has sufficient alignment and supply power, the manufacturing cost of the device is high, and the noise caused by the vibration during operation is extremely large. , bad working environment. Furthermore, in order to make processing smoother with the next processing machine, etc., if a surface treatment is applied to make the surface slippery, the alignment ability of this vibrating automatic alignment and conveyance device will be reduced.
There are problems such as insufficient supply to processing machines.

The present invention attempts to solve the problems of the above-mentioned conventional devices. In other words, the purpose of the present invention is to simplify the device and make it inexpensive, to significantly reduce the noise during operation, and to prevent the automatic alignment and conveyance ability from decreasing even when surface treatment is applied to short cylindrical objects. An object of the present invention is to provide an automatic alignment and conveyance device for short cylindrical objects.

B. Structure of the invention a. Means for solving the problem The automatic alignment and conveyance device for short cylindrical objects of the present invention has two rollers 1, 1 arranged and conveyed by an outer diameter D of the short cylindrical objects 2 to be aligned and conveyed. Motors 5, 5 are installed horizontally at an interval W, which is a slight addition of a dimension to , and motors 5, 5 are provided so that the opposing circumferential surfaces 3, 3 of both rollers 1, 1 rotate upward, and above both rollers 1, 1. A supply means 6 for supplying the short cylindrical object 2, a conveying means 7 for conveying the short cylindrical object 2 that has passed between the rollers 1 and 1 to a predetermined location, and a conveying means 7 for unaligned objects on one side in the middle of the conveying means 7. A chute 10 is provided, and an oblong auxiliary alignment plate 8 is provided above the conveying means 7 at the location where the chute 10 is provided, so that the distance between the lower edge of the plate and the upper surface of the conveying means 7 is outside the short columnar object 2. It is slightly larger than the diameter D and is provided diagonally across the conveying means 7 so that the side end of the auxiliary alignment plate 8 on the conveying direction side is on the chute 10 side.

In the above configuration, the two rollers 1, 1 may be cone-shaped as long as the distance W is constant. The material of both rollers 1, 1 is desirably surface-treated iron, but is not limited thereto depending on the material of the short cylindrical object 2. The distance W between both rollers 1, 1 is
The outer diameter D of the short cylindrical object 2 has a slight dimension, for example 2~
Set it to something with 3mm added. Further, it is preferable that the distance W between the rollers 1 and 1 can be adjusted in case different types of short cylindrical objects 2 are to be handled.

The means 6 for supplying the short cylindrical objects 2 may be, for example, a capillary type conveyor or a bucket type conveyor as shown in the figure, or other means, and the short cylindrical objects 2 may be dropped onto both rollers 1, 1 via an inclined plate 9. . Further, the conveying means 7 is provided with a processing machine (not shown) at a lower position between both rollers 1, 1.
It can be placed facing the side. For example, a chain conveyor or the like may be used as long as it can place the aligned short cylindrical objects 2 and convey them as they are.

The auxiliary alignment plate 8 is provided above the conveyance means 7 at the location where the chute 10 is provided. The auxiliary alignment plate 8 has a horizontally long shape, and its lower edge and the conveying means 7
The distance from the top surface is made slightly larger than the outer diameter D of the short cylindrical object 2, and the top of the conveying means 7 is diagonally crossed, that is, the side end of the auxiliary alignment plate 8 on the conveying direction side is on the side of the chute 10. It is set up so that In addition, the height of this auxiliary alignment plate 8 from the conveyance means 7 is set so that short cylindrical objects 2 having different outer diameters D are aligned and conveyed.
Make it adjustable.

In the figure, 4 and 4 are guide plates, and 10 is a chute of the misaligned short cylindrical objects 2.

b. Effect In the operating state of the present invention, the rollers 1, 1 are rotated by the motors 5, 5, the feeding means 6 is driven with the conveying means 7 moved, and the short cylindrical objects 2 are automatically aligned. It is randomly dropped above both rollers 1 and 1.

As a result, the short cylindrical object 2 falls to the upper part between the rollers 1 and 1 as shown in FIG. It is set by adding a slight dimension to
Therefore, the short cylindrical object 2 whose center line is parallel to the center line of both rollers 1, 1 passes through the interval W between both rollers 1, 1, which is slightly wider than its outer diameter D. It falls onto the transport means 7 below.

On the other hand, a short cylindrical object 2 whose center line is not parallel to the center line of both rollers 1, 1 cannot pass through the interval W, and both rollers whose opposing peripheral surfaces 3, 3 are rotating upward. It is rolled by 1,1. Due to this rolling, the short cylindrical object 2 remaining on both rollers 1, 1 gradually changes direction, and among them, the short cylindrical object 2 whose center line is parallel to both rollers 1, 1 as described above is formed. 2 falls onto the conveying means 7 below through the distance W between the two rollers 1,1.

As a result, the short cylindrical objects 2 are aligned and transported in the same direction on the transport means 7.
In the above, depending on the case, some short cylindrical objects 2 may further fall on top of the short cylindrical objects 2 arranged on the conveying means 7, and in rare cases, both rollers 1, 1
There is also a short cylindrical object 2 that passes upright between them. These short cylindrical objects 2 are conveyed on the conveying means 7 in an overlapping or upright state, and the auxiliary alignment plate 8 acts on them.

That is, when the conveying means 7 carrying the short cylindrical object 2 moves, it passes below the auxiliary alignment plate 8.
The auxiliary alignment plate 8 is located on the conveying means 7 at a position slightly higher than the outer diameter D of the short cylindrical object 2. Therefore,
The short cylindrical objects 2 that are well aligned on the conveying means 7 pass directly under the auxiliary alignment plate 8, but if there are short cylindrical objects 2 that overlap or stand upright as described above, , they hit the auxiliary alignment plate 8 and are removed laterally, falling down the chute 10 as shown by arrow t in FIG. Therefore, the short cylindrical object 2 on the conveying means 7 after passing through the auxiliary alignment plate 8 is
All of them are aligned, and then they are transported to the processing machine.

If the short cylindrical objects 2 have different outer diameters D, this can be accommodated by changing the distance W between the rollers 1 and the height of the auxiliary alignment plate 8.

Further, the space between the rollers 1 and 1 may be cylindrical as shown in FIGS. 1 and 2, but may also be cone-shaped as described above (see FIG. 5). By having a cone shape and facing each other in opposite directions, even if the rotation speed of the motors 5, 5 is the same, the circumferential speeds of the opposing circumferential surfaces 3, 3 of both rollers 1, 1 are different, and the short cylindrical object on both rollers 1, 1 is 2 makes it easier to roll. Therefore, the direction of the short cylindrical object 2 tends to change, and its center line becomes parallel to both rollers 1, 1, making it easy to fall.

C. Effects of the Invention As is clear from the above, the automatic alignment and conveyance device of the present invention has a simpler configuration than the vibrating automatic alignment and conveyance device commonly used in the past, and therefore can reduce equipment costs.

Moreover, since the structure is simple, failures are less likely to occur, and subsequent overhauls, adjustments, etc. can be performed easily and quickly.

When this device is operated, there is almost no noise compared to the large noise caused by conventional vibrations, and the environment at the work site can be greatly improved.

Furthermore, even if the short cylindrical objects are subjected to a surface treatment in advance to facilitate subsequent processing, the alignment and transport functions are not affected at all, unlike conventional methods, and they can be aligned and transported quickly in accordance with the capacity of the processing machine.

Furthermore, when aligning and conveying short cylindrical objects with different outer diameters, it is only necessary to change the distance between both rollers and the height of the auxiliary alignment plate, making it possible to handle the process easily and quickly. , and other useful effects.
