Description

[0001] Auto supply equipment of flange [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic flange feeding device, and more particularly, to a device for automatically feeding flanges one by one to a flange mounting device side.

Generally, a pipe is connected by a straight line to another end or one end of the pipe, or a flange is attached to another pipe to connect the pipe to another part.

For example, in the case of an air conditioner, a flange is fastened to an end portion of a refrigerant pipe to improve a coupling force between refrigerant pipes.

In this case, the pipe is inserted into the insertion hole of the flange, and then the pipe is inserted into the flange through a caulking operation or the like, and the pipe is inserted into the insertion hole of the flange. Tightly coupled.

Since the method of attaching the flange to the pipe usually depends on the manual operation of the operator, it is difficult to accurately assemble the flange to the pipe, resulting in poor work efficiency and difficulty in securing the quality.

Accordingly, in recent years, most of the automatic flange attaching apparatuses that automatically press-fit the flanges to the pipes are used.

Such a flange automatic attaching system is a method in which a flange supplied one by one by a worker is picked up by a chuck, and then forcedly press-fitted to an end of a pipe set on a jig to attach the flange to a relatively accurate position And it is possible to maintain the airtightness to the flange attaching portion, thereby securing the quality of the product.

However, in the conventional automatic flange mounting system, since the flange is supplied manually, there is a disadvantage in terms of productivity and safety.

For example, there is a drawback in that productivity is greatly reduced due to the work efficiency being lowered because the work is carried out in such a way that the worker puts one flange on the chuck while sticking it to the chuck, and the hand holding the flange must be inserted into the equipment while driving Therefore, there is always a risk of safety accidents, and there is a considerable difficulty in securing the quality.

Accordingly, the present invention has been made in view of the above, and it is an object of the present invention to provide a new type of automatic flange feeding method that automatically performs the entire process of putting the flange from the flange loading direction after fitting the flange at the end of the pipe The object of the present invention is to provide a flange automatic feeder capable of ensuring the quality of products as well as improving the productivity by automating the entire process related to the supply of flanges and basically eliminating the risk of safety accidents during operation.

In order to accomplish the above object, the automatic flange feeding device provided in the present invention has the following features.

Therefore, the automatic flange feeding device is installed at one side of a facility for assembling a flange to a pipe, and automatically supplies the flanges one by one in association with the flange assembling process, thereby improving the efficiency of the entire flange assembling process.

The flange feeding guide of the automatic flange feeding device may further include a pair of stopper cylinders installed on the bottom discharge side to sequentially discharge the flanges from the lowest flange one by one.

The flange holder portion of the automatic flange feeding device includes a holder block connected to the rod of the loading cylinder and moving left and right while being guided by the LM guide on the base, a motor installed in the holder block, And a holder that holds the flange.

Accordingly, the flange holder part can be operated in such a manner that the flange holder part is caught by the flange in the flange loading block, then rotated, and the flange holder part is inserted into the assembly facility in the aligned state.

In addition, in the case of the holder in the flange holder portion, the holder rod is connected to the rod of the motor and is extended on the axis line, and is rotatably installed on the holder block via a bearing. The holder rod is coupled to the distal end portion of the holder rod And a holder jig having a clamping pin fitted in a hole in the flange as a means for substantially holding the flange.

The automatic flange feeding device provided in the present invention has the following advantages.

First, the entire process related to the flange input, such as continuous feed of the flange by the feeder and input of the flange by the loader, is performed by an automated process, thereby making it possible to significantly increase the productivity due to the improvement of the process efficiency.

Second, since the load is automatically applied to the flange by the loader, the defect rate of the process can be reduced and the product quality can be secured.

FIGS. 1A and 1B are perspective views showing an automatic flange feeding device according to an embodiment of the present invention, and FIGS. 2A and 2B are perspective views showing a flange loading part and a flange holder part in an automatic flange feeding device according to an embodiment of the present invention .

As shown in Figs. 1A and 1B and Figs. 2A and 2B, the automatic flange feeding device is a device for sequentially feeding flanges one by one to an assembling work area of a flange assembling facility (hereinafter, referred to as a facility), and a large amount of flanges are filled And the flanges in the vibrating feeder are aligned and discharged, then moved in a row in a row, and then fed one by one to the assembly work area automatically.

For example, the flange is conveyed in a row in a row in the flange transferring part 16 to which the vibration feeder 10 and the flange conveying guide 11 belong, and at the same time, one flange is discharged. One flange is held at the flange loading section 24 and the flange holder section 14 is set at the holding position so that one flange is held by the flange holder section 14 to which the holder 22 belongs, As shown in FIG.

Accordingly, the flange can be automatically supplied to the equipment side by the continuous automatic continuous process of the flange transferring part 16, the flange loading part 24 and the flange holder part 14. [

On one side of the facility is installed a vibration feeder 10 which can be filled with a large amount of flange, where the flanges can be continuously discharged through the feeder outlet while being arranged in a vibrating feeding manner.

Such a vibration feeder can be applied to a conventional vibration feeder in which the machine parts and the like which are randomly filled are aligned and discharged one by one.

A flange transfer guide 11 is provided as means for successively transferring the flanges discharged from the oscillation feeder 10 side by side in a row.

The flange conveying guide 11 is formed in such a manner that the flange is freely dropped by its own weight and is disposed in a posture inclined at a predetermined angle from the discharge side of the vibration feeder 10 downward.

For example, the flange transport guide 11 is formed in the form of an elongated rectangular tube having an upper end inlet 11a and a lower end outlet 11b. The inlet 11a at this time is connected to the outlet of the vibration feeder 10 And the outlet 11b is extended to the working area of the flange loading part 24 and the flange holder part 14, that is, the area where the operation of picking up the flange and the operation of holding the flange are performed.

Of course, the flange is already aligned on the side of the vibration feeder 10 in a side-up position before the inlet 11a of the flange transporting guide 11, so that the flange is moved to the flange transfer guide 11, and can be stably transported.

Particularly, the flange conveying guide 11 is provided with a pair of stopper cylinders 17 as means for interrupting the flanges to be fed in a state in which they are stuck together and delivering them to the flange block 12 on the side of the flange loading section 24 one by one .

The pair of stopper cylinders 17 are disposed on both sides of the conveying guide while maintaining a predetermined distance back and forth from each other along the flange conveying direction at the lower discharge side position of the flange conveying guide 11.

That is, one stopper cylinder 17 is disposed at one side of the conveying guide at a position adjacent to the lower end outlet 11b toward the direction transverse to the flange advancing direction, and the other stopper cylinder 17 is disposed at the lower end outlet 11b At a position spaced upward a predetermined distance along the flange advance direction, and also at a side opposite to the other side of the feed guide so as to cross the flange advance direction.

Each of the stopper cylinders 17 disposed in this manner is supported by the structure of the cylinder body to be fixed to the flange transfer guide 11. At this time, the rod of the stopper cylinder 17 is positioned across the inside of the transfer guide, It can be blocked or passed.

As a result, the pair of stopper cylinders 17 can be sequentially discharged one by one from the lowest flange while operating alternately.

For example, in a state in which the rod of the upper stopper cylinder 17 blocks the flange row, one of the flanges at the lowest position opens the outlet 11b while the rod of the lower stopper cylinder 17 is opened (cylinder backward operation) When the rod of the upper stopper cylinder 17 is opened in a state where the rod of the lower stopper cylinder 17 is closed, one flange is lowered down to stand by and the two stopper cylinders 17 The flanges can be sequentially discharged one by one by the alternate operation.

In addition, a flange loading unit 24 is provided to allow one flange to be discharged from the flange transferring unit 16 side to be held by the flange holder unit 14.
