Description

[Detailed Description of the Invention] The present invention relates to a parts feeder that reliably aligns various parts in a fixed direction and discharges them.

Conventional parts feeders use a vibrator to vibrate a tray into which many parts are loaded, and use this vibration to align the parts in a line along the inner peripheral wall of the tray and take them out one by one. That's what I do.

However, with this method, although it is possible to align each component in the longitudinal direction, it is difficult to ensure alignment in the front-back direction.

In particular, automatic machines that combine parts feeders and various processing machines are required to reliably align the directions of supplied parts.

In view of this, the present invention combines two vibrators and provides a special direction alignment means for one vibrator to ensure that the directions of each part are aligned, as well as to periodically discharge the vibrator and connect it directly to an automatic machine. It was made possible to do so.

The present invention will be explained below based on examples.

In the figure, reference numeral 1 denotes a deep dish-shaped saucer with a vibrator 2 at the bottom for storing a required number of parts such as long nuts and box wrenches. Each component is guided out in a line by a spiral guide 3 provided along the inner peripheral surface of the tray.

Also, the parts feeder main body A consists of the saucer 1 and the vibrator 2.
An auxiliary parts feeder B is provided adjacent to the auxiliary parts feeder B to ensure that the direction of the parts is constant.

The parts feeder B has a vibrator 4 at the bottom and a deep dish-shaped saucer 5 at the top, and a shallow dish-shaped table 6 smaller than the inner diameter of the saucer 5 is integrally installed inside the saucer 5. 4
Both the tray 5 and the table 6 are made to vibrate, and the tray 5 and the tray 1 of the parts feeder main body are electrically connected at their adjacent portions.

Further, a rotary disk 7 is provided on the top surface of the table 6, which rotates in the same direction due to the vibration of the table and the drive of the motor, but in this case, the rotary disk 7 has a diameter smaller than that of the table.
It also rotates concentrically on the table.

This is installed in the saucer 5, and a shaft 10 for supporting the table passes through the center of the table and projects onto the top surface of the table, so that the center of the rotary disk is inserted into this shaft 10, and the rotary disk 7 is connected to the table. It is rotated around the shaft 10 while sliding on the top.

Furthermore, a large number of guide rods 7b, 7b, .
, 7b is provided with an engaging pin 7a between the guide rods 7b, ? The engaging pins 7 are arranged so that each part sent out one by one in a certain direction fits therein, and supports the parts while sliding on the top surface of the outer peripheral part of the table.
A hole Ga drilled in the end face of the component G is inserted into a, thereby ensuring that the directions of the components are aligned.

Therefore, the diameter of the engaging pin 7a is determined so that it fits only into a hole drilled on one end of the component and does not fit into the hole on the other end, and is determined depending on the size and shape of the component. This allows the user to select from a plurality of rotary disks with different pitches between guide rods and engagement pin diameters.

Furthermore, when this part is fitted into the engaging pin on the outer periphery of the rotating turntable and is transferred while being sandwiched between the guide rods and sliding on the top surface of the table by the rotation of the turntable, this part will not move beyond the engaging pin. The outer circumferential side of the top surface of the table is shaped to be higher so that it does not come off.

A boo 1J11 is fixed to the upper surface of the rotary table, and a belt 13 is stretched between this pulley 11 and the pulley 12 of the motor M installed on the parts feeder body frame F, and the rotary disk rotates on the table due to vibration. The rotation is made by adjusting the rotational speed while keeping the force at a constant speed using this motor.

In this case, the rotary disk and pulley are integrated, and the shaft 10
The shaft 10 is loosely fitted to rotate freely and prevent the rotary disk from vibrating on the table and making noise due to vibration.
A fixing member 14 adjustably fixed to the table is configured to constantly press the rotary disk with a certain pressure on the top surface of the table via a compression spring 15 and a thrust bearing 16.

In addition, in order to line up the parts between the guide rods of the rotary disk on this table and feed them one by one, one end 3a of the guide 3 provided in the tray of the parts feeder main body A is extended to the top of this table, and this guide An arc-shaped guide 17 is supported on the shaft 10 so as to face the end 3a of the rotary disk 7 and along the outer circumferential surface of the rotary disk 7.
The parts are surely transferred from the parts feeder A to the table of B while being regulated by the guide 17 via the parts feeder A.

Furthermore, when parts are supplied onto this table and are slid on the table by the rotation of the rotary disk while being sandwiched between guide rods, the holes on the end faces of the parts are fitted into the retaining pins due to the vibration of the table. However, if the orientation of the parts supplied on this table is different, and if the supplied article is in a standing state, even if vibration is applied to the part, this part will not be perpendicular to the engaging pin 7a. Even if the component is parallel to the engagement pin, the shape and size of the holes on both end surfaces of the component may be different. Therefore, even if the small hole side faces the engagement pin, it will not be fitted.

For this reason, parts supplied while standing on the table are pushed out toward the outer circumference of the table by the tip of the guide 17, which is hung vertically above the table, so as not to come into contact with fallen parts, as shown in Figure 5. Items that fall into the tray, and items that have fallen but are in the opposite direction and are not engaged with the retaining pins.
Only the parts engaged with the engagement pins are further transferred on the table and sent to the next process via a discharge chute 8 provided in the tangential direction of the table. In this case, the chute 8 is transferred from a rotary disk on the table. A guide 9 is provided at the tip of the chute 8 to ensure discharge to the side.

In addition, among the parts transferred on the table, if the direction is reversed and the part is not fitted with the engagement pin, when it reaches the notch in front of the chute 8, the part will be moved on the table by its own weight at this position. It begins to tilt from the outer edge of the notch and falls from the notch into the saucer, but if the part is correctly fitted to the engagement pin, a tilting force is applied to the part at the notch due to its own weight. Even if the chute is moved, it is supported by the engaging pin and slides on the table to move to the next chute side.

Then, only the parts that have been transferred in the opposite direction fall from the notch into the receiving tray.

The fallen parts are moved by the vibration of the receiving tray to the receiving tray of the parts feeder A which is electrically connected to the receiving tray, and are sent out again via the guide.

According to the present invention, the parts fed out in alignment from the parts feeder main body are meshed with a guide rod of a rotary disk which is rotated at a constant speed by vibration and a motor in the receiving tray of the adjacent parts feeder. The parts are transported in such a way that they are aligned in a certain direction, and only the parts that are aligned in a certain direction are supported and guided to the discharge chute, while the parts that are in other directions are allowed to fall from the rotary disk, so the parts are sent out in alignment. It has the advantage that it can be reliably oriented and discharged periodically, and that accurate processing can be performed even when used in combination with an automatic processing machine.
