Abstract

PURPOSE:To aim at enhancing and stabilizing the efficiency of supply, by arranging an aligning conveyer which runs at a speed higher than that of a supply conveyer in the same direction as that of the supply conveyer in parallel therewith, and by securing a push-out wall and an aligning wall above the supply conveyer and the aligning conveyer, respectively. CONSTITUTION:A workpiece conveyed by a supply conveyer 1 abuts against a push-out wall 6, and is then conveyed toward an aligning conveyer 3. Further, it is pushed out onto the aligning conveyer 3 which runs at a speed higher than that of the supply conveyer 1. When the center of gravity of the workpiece passes over the terminal end of the push-out wall 6, the workpiece may be conveyed at a high speed by the aligning conveyer 3. Accordingly, a space may be obtained between workpieces which are therefore moved in order along an aligning wall 5. With this arrangement, it is possible to stabilize the supply of workpieces.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to the supply of parts. 0 A stable supply of parts is an essential task for automation, including automatic assembly, and the success or failure of this automation depends on the automation. The present invention relates to automatic supply as part of automation, and is applicable to all industrial fields where automation is performed.

BACKGROUND OF THE INVENTION Conventionally, parts have been fed using feeding machines such as vibrating parts feeding machines and rotating parts feeding machines. These feeders use arcuate alignment tracks to align one part, and because it is difficult to draw them in drawings, manufacturing often depends on the skill of the manufacturer. Since it is an arc-shaped alignment track, the parts to be supplied are always subject to centrifugal force.
This caused unnecessary friction with the alignment wall, reducing the efficiency of alignment. The belt-type feeder that the applicant previously applied for (described in the patent application filed on March 20, 1986) separates the parts to be fed placed on the alignment conveyor and then separates them individually. Although the parts to be supplied are aligned and supplied in one direction, it is not possible to separate the parts to be supplied and provide sufficient spacing between the parts, resulting in decreased feeding efficiency and malfunctions. There were times when I did The present invention compensates for the deficiencies of the earlier application.

Problems to be Solved by the Invention The present invention moves the parts to be supplied in a straight line and interacts with the alignment wall, and selects whether the posture is correct or not based on the position of the center of gravity of the parts to be supplied, or by using a senna. By sorting, the parts to be supplied are aligned in the required posture, but the supply is stabilized by providing sufficient spacing between the parts to determine the orientation of the parts to be supplied. It is something to measure.

Means for Solving the Problems The present invention will be explained by way of examples. FIG. 1 is a sketch showing the structure of the present invention. 1 is a supply belt, and an alignment belt 3 is provided on one side of the supply belt 1 in parallel without any gaps.

The drive shaft 2 drives the supply heald 1 and is connected to the motor via a drive source (not shown), such as a speed reducer. The alignment belt 3 is driven by a rotating shaft 4, and the rotating shaft 4 is connected to the motor via a rotation source (not shown), such as a speed reducer. The drive source and rotation source of the alignment belt 3 are adjusted so that it runs at a higher speed than the supply belt 1. It does not change the spirit of the present invention to connect the drive shaft 2 and the rotation shaft 4 through a mechanism that transmits and increases/decreases rotation, such as a gear, a belt, and a pulley, and to share a rotation source and a drive source. As for the belt and alignment belt, an endless belt, plate chain conveyor, etc. are selected depending on the weight and material of the parts to be supplied.

In order to easily transfer the supplied parts from the supply conveyor l to the alignment conveyor, it does not change the spirit of the present invention to install the alignment conveyor at a position somewhat lower than the supply conveyor.

FIG. 2 is a top view of the mechanism of the invention.

An extrusion wall 6 fixed to a member not shown above the supply conveyor 1, and an alignment wall 5 continuous to the extrusion wall 6 and fixed to a member not shown north of the alignment conveyor 3 are provided. The extrusion wall 6 is provided above the supply conveyor 1 so as to diagonally cross the supply conveyor 1. The terminal end of the extrusion wall 6 and the start end contact the alignment wall 5 to prevent the supplied parts from entering or getting caught between the extrusion wall 6 and the alignment wall 5. The extrusion wall 6 and the alignment wall 5 are installed so that the end of the extrusion wall 6 and the start end of the alignment wall 5 are located above the alignment conveyor 3 and as close to the supply conveyor 1 as possible. The alignment wall 5 is provided above the alignment conveyor 3, gradually extends to the outside of the alignment conveyor 3, and reaches the discharge port 8 at a certain distance from the outside of the alignment conveyor 3 depending on the shape and size of the supplied parts. . It does not change the spirit of the present invention to attach attachments such as recesses, protrusions, etc. for alignment to the alignment wall 5, or to attach a sensor and a removal mechanism. Further, it does not change the spirit of the present invention to attach a wall to the outer periphery of the supply conveyor 1 around the starting end of the supply conveyor 1 to prevent tax losses on supplied parts.

Operation The operation will be explained with reference to FIG. The supply conveyor 1 is operated at a slower speed than the alignment conveyor 3. The parts to be supplied are fed into the starting end 7 of the supply conveyor l. Extruded wall 6
is provided diagonally across the supply conveyor 1 to the north of the supply conveyor 1, so the parts to be supplied are placed on the supply conveyor 1.
The material is conveyed on the conveyor, hits the extrusion wall 6, and is moved by the extrusion wall 6 toward the alignment conveyor. Since the aligning conveyor 3 is operated at a faster speed than the supply conveyor, the parts to be supplied that have moved on the supply conveyor along the extrusion wall 6 will have their center of gravity passing through the end of the extrusion wall 6. At the same time, they ride on the alignment conveyor 3 and are moved by the alignment conveyor 3 at a high speed, so that the supplied parts have a distance between each other and are moved by the alignment conveyor 3 along the alignment wall 5 at 0 intervals. The supplied parts having the same size are pushed out to one side of the alignment conveyor 3 by the alignment wall 5, and are mechanically sorted according to the shape of the supplied parts and the position of the center of gravity based on the relationship between the outside of the alignment conveyor 3 and the alignment wall. Alternatively, a sensor attached to the alignment wall 5 determines the situation of the good point and aligns the items. The parts to be supplied that have been arranged in a desired posture are conveyed to the discharge port 8 while riding on the arrangement conveyor, and are arranged and supplied. Further, supplied parts having an incorrect orientation other than the required orientation are sorted out and fall from the alignment conveyor 3, or are forcibly removed by the removal mechanism.

Normally, the alignment conveyor is installed horizontally,
It is a feature of the present invention to install the alignment conveyor by tilting it left and right or with a slope in the ascending and descending directions, and by tilting the supply conveyor left and right or installing it with a slope in the direction of movement corresponding to the installed state of the alignment conveyor. It doesn't change the purpose.

Embodiment FIG. 3 shows a feeder equipped with a hoe and a pawl in which the present invention is implemented. Alignment conveyor 3 provided parallel to supply conveyor 1
A sliding wall 13 on which the parts to be supplied slide down is provided on the outside of the sliding wall 13, and a hopper 12 that opens is attached to the lower end of the sliding wall 13.

A hopper belt 11 is attached to the bottom surface of the hopper 12.
The lower side of the side wall of No. 2 and the hopper belt are attached without any gap.

A transfer conveyor 14 is installed extending from below the terminal end 15 of the hopper bell 11 to above the starting end of the supply conveyor I.

The parts to be supplied are put into the hopper 12, and the hopper bell)
11 towards the end 15 of the hopper belt. From the end 15 of the hopper belt 11, the parts to be fed fall while being separated onto the transfer conveyor 14, and are conveyed by the transfer conveyor 14 onto the supply conveyor 1. Since the speed of the supply conveyor is high compared to the speed of the transfer conveyor 14, the parts to be supplied are further separated and moved by the supply conveyor I. The supplied parts transferred by the supply conveyor l are
The parts to be fed are transferred to the alignment conveyor by the extrusion wall 6 and transferred by the alignment conveyor 3, and are sorted by the alignment wall, and only the parts to be fed in the correct posture are carried on the alignment conveyor and removed from the discharge port 8. is carried out. The parts to be supplied that are different from the intended posture are rejected to the sliding wall 13 and are removed from the sliding wall 1.
3 and is returned to the hopper 12.

In FIG. 4, instead of using a flat belt for the alignment conveyor 3, a convex conveyor is used to further improve the separation effect. An alignment conveyor 3 is installed parallel to a supply conveyor 1 driven by a drive shaft 2. The starting end of the alignment conveyor 3 is located at a lower position than the supply conveyor 1. Since the E surface of the roller 26 is located at a higher position than the supply conveyor 1, the G row conveyor 3 ascends from the starting end toward the roller 26, and a part of the ascending plate portion 23 is at the same height as the supply conveyor. Become. After the alignment conveyor 3 passes the roller 26, it becomes a downward slope 2.7 and reaches a rotating roller 24 having a rotating shaft 4.

The parts to be supplied, which have been placed at the starting end of the supply conveyor, are moved by the supply conveyor 1 and moved toward the alignment conveyor 3 by the extrusion wall 6. The extrusion wall 6 is joined to the alignment wall 25 near the point where the uphill slope 23 of the alignment conveyor 3 and the supply conveyor l are at the same height, so the parts to be supplied are aligned along the extrusion wall. Transfer to conveyor 3.

The lower end of the alignment wall 25 is made so as to be close to the surface of the alignment conveyor and reaches the end of the downhill slope 27, so that the parts to be fed are carried along the alignment wall 25 by the alignment conveyor 3, and the parts are transported by the alignment conveyor 3 along the alignment wall 25, They will pass over the alignment conveyor 3. When passing above the roller 26,
The curvature of the roller 26 widens the distance between the upper parts of the parts to be supplied, so by utilizing this spread, the sensor attached to the alignment wall 25 above the roller 26 can easily count the parts to be supplied and determine the orientation. be able to.

In the present invention, the supply conveyor and the alignment conveyor may be a transfer belt with a flat surface or a type of conveyor with flat small pieces attached to the top surface, but the gist of the present invention will not change. do not have.

Effects of the Invention The present invention not only makes it possible to quickly and accurately align and supply parts, which was previously impossible, but also to perform high-speed and accurate counting of parts.

We believe that the present invention not only promotes rationalization of production such as assembly, but also greatly contributes to packaging and product management.
