 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic feeder, and more particularly, to a device applied to an automated machine for processing and producing a piston ring (material) and to a piston ring automatic feeder for stably supplying a piston ring.

 In general, in the factory of producing piston rings for automobile engines, in the process of producing piston rings of more precise specifications, in order to maintain the piston rings at a certain standard, the quality of the products is improved by automating the processing process to increase the precision and reliability of the product. I'm trying to.

 When the material is supplied to the machine during such an automated process, if the material is damaged due to the structural problem of the material supply device or the supply position is changed, the processing quality of the material cannot reach the desired quality.

As shown in FIG. 1, the conventional supply device includes a chute 10 inclined at an angle of 20 ° to which the raw material 20 is supplied, a raw material supply cylinder 30, and a raw material 20 that push the raw material 20. Escape bar 70 is pulled up and the transfer cylinder 60 for supplying the material 20 to the machining position.

When the material 20 is loaded on the chute 10, the chute 10 is inclined, so that the material 20 descends by sliding to the position of the space 80 in a natural fall method, and thus a predetermined space. Wait in in-space 80. Then, the material supply cylinder 30 advances slightly forward (towards the left side in the figure) while pushing the material 20 into close contact with the space 80, and then the escape cylinder 50 is raised to escape the bar 70. Lifting the material 20 that was waiting in the space 80 to lift up to separate the other materials in the atmosphere. At this time, the feed cylinder 60 immediately moves forward and supplies the raw material 20 to the machining position.

However, in the above type of supply device, since the material 20 is pushed down by gravity in an inclined chute, the material placed in front of the material is excessively pushed by the weight of the material. At this time, since the back of the material waiting in the space 80 is subjected to severe pressure due to the weight of the material behind, as shown in Figure 2, the upper part of the material is excessively received from the back of the weight of the material aligned state The phenomenon occurs. That is, the material to be aligned vertically is placed out of the vertical state because it is subjected to a greater force on the top, there is a concern that a lot of material is located above the appropriate amount of material to be located in the space 80 due to the pressure from the back There is also.

As such, when the material is disturbed, when the escape bar 70 is lifted and the material is raised, a jam phenomenon occurs and a proper amount of the material cannot be separated from other materials. Then, the escape bar 70 rises and at the same time the material is caught between the corner (not shown) of the space 80 and the escape bar 70 and is broken, and jam occurs at the same time, the machine is stopped and the material is deformed. There is a problem.

As described above, the conventional supply device is stopped due to abnormally supplied material and the production work is stopped due to the failure of the material and the error of the machine, so that the production line is stopped, the damaged material is removed, and the material loaded in the chute is removed. As a result, the productivity is reduced as the space must be readjusted and the material supplied again.

In addition, when the escape bar is broken, productivity is reduced and the parts are damaged and the parts are damaged by disassembling the damaged escape cylinder 50, disassembling the escape bar 70 from the supply device, and replacing the escape bar 70. There was a problem that the maintenance and maintenance costs of the supply device according to the increase.

The piston ring automatic feeding device of the present application improves the absurdity generated in such a conventional feeding device to prevent the damage of the material generated in the process of supplying the material to the machine, and to automatically maintain the piston ring in the correct quantity while securing a certain position. It is possible to improve the productivity by maintaining the processing quality of the product uniformly by supplying.

Therefore, the present invention was devised to solve the conventional problems as described above, and an object of the present invention is that the material to be supplied abnormally or the material to be supplied to the supply device applied to the automated factory is damaged or damaged during the supply process. It is to provide a supply device for preventing the supply device from being broken.

The piston ring automatic supply device according to the present invention as described above will be described in detail with reference to the accompanying drawings.

As shown in FIG. 3, the supply apparatus for achieving the object of the present invention includes a horizontal type chute 130 on which the material 120 is loaded, and the materials loaded on the chute according to a supply cycle. A main pusher unit 160, at least one ball screw 150 for horizontally moving the pusher unit 160, and the LM guide 140 for maintaining a precise straightness during the movement of the pusher unit 160 And, the air cylinder 162 for transporting the pusher unit 160 up and down, sensors (111, 131) for detecting the presence or absence of the material to be automatically supplied to detect the material loaded in the chute, the pusher unit It consists of a sensor 121 for sensing the material 120 supplied by 160.

As shown in FIGS. 4 and 5, the pusher unit 160 includes a driving motor 170 for driving the pusher unit 160 along the ball screw 150, and a rotational force of the driving motor 170. It is composed of a timing belt 171 to be transmitted to the ball screw 150, a pusher plate 161 for pushing the material, and a spring 165 for buffering the material and the pusher plate 161.

Referring to FIG. 3, in the supply apparatus according to the present invention as described above, the positions of the sensors 111 and 131 are set according to the one-time supply amount of a predetermined material, and the sensor 131 when the one-time supply material is loaded in the chute. ) Detects the material and drives the pusher unit 160 to supply the material by pushing the material.

The pusher unit 160 is provided with a pusher plate 161 for directly pushing the material, and a spring 165 is installed at the rear side of the pusher plate 161 to accurately and smoothly push the material 120. When the material pushed to the supply position by the pusher plate 161 reaches the position detected by the sensor 121, the pusher unit 160 stops the advance of the pusher plate 161 which pushes the material and the Back up about 1-2mm for free supply.

As described in the prior art, the material pulled up while the escape bar 70 is raised is supplied to the processing position by the transfer cylinder 60.

The sensor 121 which detects the material at the same time as the material rises sends a no-material signal to the PLC (not shown), and immediately the footer plate 161 arrows the material 120 loaded on the chute 130. The sensor 121 advances the material 120 to the position where the sensor 121 can detect the material by pushing in the direction, and then moves backward 1-2 mm for free supply of the material.

If there is no material in the chute 130 on which the material is loaded (if the material runs out), the footer unit 160 does not have a material detection signal in the sensor 121 even though the footer plate 161 is advanced to the forefront. It descends by the air cylinder 162, and then backs to the starting position.

The reason why the pusher unit 160 moves downward is to prevent the pusher unit 160 from colliding with the material while moving backward when the material remains in the chute.

When the material is loaded into the chute 130 again and the sensors 111 and 131 detect the material, the pusher unit 160 is lifted by the air cylinder 162 to start moving forward to push the material to repeat the supply cycle. do.

As described above, the automatic supply of the piston ring according to the present invention prevents damage to the material caused by the collision of the ring due to the natural fall, which has conventionally occurred in the processing of the piston ring, which requires extreme precision. It has an effect of preventing the damage of the escape bar of the processing machine due to the jam (jam) phenomenon.

In addition, the pusher plate feeds the material to the supply position of the escape bar and then retreats backward for free supply of the material, thereby improving the quality of the material because there is no friction with the side of the material when the material is lifted by the escape bar. Has

Therefore, the automatic piston ring supply device according to the present invention is to remove the damaged material in the case of the supply object or the supply device is broken and the supply device is separated from the machine to remove the broken parts from the machine to remove the new parts It is effective to prevent the decrease in productivity due to the assembly of the supply device, and to eliminate the factors that increase the maintenance and maintenance cost of the supply device due to the breakage and replacement of parts and the increase in production cost due to material damage. It works.
