Description

Anti-overlapping mechanism of automatic feeding system of pipe cutting machine

Technical Field

The utility model belongs to the technical field of the laser pipe cutting machine, concretely relates to pipe cutting machine automatic feeding system's anti-overlapping material mechanism.

Background

At present, the pipe processing technology is rapidly developed, the application of steel pipes in various industries is quite wide, the standard length of a steel pipe leaving a factory is 6 meters, but different processing requirements are met due to different application scenes, and cutting, bending, welding and punching are commonly used in metal pipe processing. The cutting and punching processes are the most diversified, a plurality of steel pipe enterprises are changed on the basis of original sawing by the laser pipe cutting machine, the cutting efficiency of the traditional saw blade is low, the pipe is easily extruded and deformed in the cutting process, and the saw blade is a large-consumption accessory. The laser pipe cutting machine can meet the requirement of non-contact batch cutting and does not need secondary processing; more pipes can be applied to the industries such as door and window guardrails, automobiles, bicycles, motorcycles, agricultural machinery, fitness equipment, sports goods and the like, and the laser pipe cutting machine has been driven into various industries by virtue of a processing mode with high efficiency and low cost and is deeply applied. The intelligent laser pipe cutting machine adopts a servo control system, and has the advantages of full-automatic feeding, blanking, cutting and highest cutting precision reaching +/-0.1 mm. Can set various different cutting lengths and output and can automatically complete cutting. For example, a section of stainless steel pipe is cut by the original saw blade for 15 seconds, but the cutting time is up to 2 seconds nowadays, and the efficiency is improved by nearly 10 times. The automatic steel pipe loading and unloading device has the advantages that a certain amount of steel pipes are placed on the loading frame, manual watching is not needed, labor cost is really saved for people, the automatic steel pipe loading and unloading device has the functions of material-free shutdown, detection alarm, fault removal display and automatic calculation shutdown, and management is convenient.

The full-automatic feeding system is an important component of the pipe cutting machine, so that the operation is more intelligent, and both hands are thoroughly liberated. The one-time feeding of a 6m feeding system can reach 3 tons of pipes, the pipes are placed in a material frame for standby (figures 1 and 10), and the subsequent steps are all automatically carried out. The most important competitive parameters of the full-automatic feeding system are the working efficiency and the influence on the shutdown times. And material stacking is a primary problem affecting shutdown. Reduce the material frame and promote the number of times and can improve work efficiency, when transporting non-circular tubular product especially than thin tubular product, because the randomness of tubular product piling up takes place very easily and fold the material phenomenon for example only not leave a tubular product after sorting device motion, when leaving more than a tubular product, the putting of tubular product has multiple possibility (figure 6, for example two rectangular pipes stack together, a rectangular pipe minor face down another rectangular pipe long side down and two rectangular pipes paste very closely), at this moment limit material axle touch the condition that just appears reporting to the police that stacks tubular product, need manual intervention, automatic feeding procedure is eventually disconnected, shut down at this moment.

The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

The following describes the present invention with reference to the accompanying drawings.

As shown in fig. 1, an anti-overlapping mechanism of an automatic feeding system of a pipe cutting machine comprises a conveying chain 1, a first cylinder 2, a material blocking rod 3, a sorting plate 4 and a second cylinder 5; the conveying chain is installed on the frame 6 and used for conveying pipes 7, the cylinder body of the first air cylinder is hinged to the side portion of the frame, the piston rod of the first air cylinder is hinged to the middle of the material blocking rod, one end of the material blocking rod is hinged to the side portion of the frame, when the first air cylinder works, the other end of the material blocking rod is driven to stretch out of the side portion of the conveying chain, one end, located at the initial position of the conveying chain, of the sorting plate is hinged to the frame, the middle of the sorting plate is hinged to the piston rod of the second air cylinder, and the cylinder body of the second air cylinder is hinged to the frame. In order to sense whether the pipes on the conveying chain are overlapped or not, a material limiting shaft 8 is arranged above the rack and is of an existing structure, the purpose is to detect whether the pipes are overlapped or not, the principle is that the two sensors are different in horizontal height, when the material limiting shaft is lowered to the lowest position, the pipes collide with a sensor 10 on the upper portion if the pipes are overlapped, and a first cylinder in the device is informed to drive a material blocking rod to work. In order to facilitate containing the pipes, the front end of the rack is provided with a material frame 9, and the pipes in the material frame enter the sorting plate through the overturning of the material frame and then enter the conveying chain through the sorting plate. When the material frame transports tubular product to the conveying chain, the letter sorting board lifts through the cylinder motion, blocks most tubular product, when detecting out to take place to fold the material, all the other tubular products are transported to the material blocking rod tip position through inverter motor by the conveying chain, and the material blocking rod is through first cylinder up-and-down motion, and the rotation that lies in material blocking rod tip tubular product and can follow the material blocking rod takes place the displacement or rotates to change the arrangement of tubular product on the conveying chain. A sorting plate and a material blocking rod are arranged beside each group of conveying chains, so that the pipe is uniformly stressed and is suitable for pipes with different lengths. The cylinder has short stroke, simple structure, convenient installation and low cost. One variable frequency motor drives four conveyor chains to be driven, and the shafts are synchronous by using a coupling. The conveying chain is a rubber chain, so that the abrasion resistance and the shock resistance are increased, the conveying is convenient, and the reciprocating motion is performed when the material stacking occurs.

During the use, as shown in figure 1, the material frame promotes tubular product, transports a plurality of tubular products to the conveying chain on, and meanwhile the letter sorting board promotes, can leave all the other tubular products of a pipe under the normal condition and collude, hinders the simultaneous movement of material pole to prevent that a tubular product that leaves from rolling to the place ahead. When the time limit material axle moves to the sorting device tip position, whether the detection tubular product is single-deck and puts things in good order as required. When transporting non-round tubes, especially thinner tubes, stacking of tubes is more likely to occur, e.g. when more than one tube is left, rather than leaving only one tube after the sorting device has moved (fig. 6, e.g. two rectangular tubes stacked together, one rectangular tube with short side down and the other rectangular tube with long side down and two rectangular tubes close together)

When the material limiting shaft touches the material stacking pipe, the material limiting shaft does not stop and generates a feedback signal, and the equipment is executed according to the following method:

the material limiting shaft returns to the initial position: the horizontal direction is forward and the vertical direction is upward. To avoid subsequent tubing movement and to prevent collisions, as shown in figures 4 and 5.

The transport device transports the tube material to be stacked to the end position of the blocking rod, as shown in fig. 4 and 5.

The material blocking rod cylinder moves, and as shown in fig. 3, the pipe located at the end of the material blocking rod can displace or rotate along with the rotation of the material blocking rod, so that the arrangement mode of the pipe on the conveying chain is changed, and the problem of material stacking is solved.

The transport equipment then transports the tube, which has solved the problem of stacking, back to the initial collision position, as shown in fig. 4.

And the transportation equipment and the material limiting shaft are restored to normal work. If the material limiting shaft detects the material stacking again, the steps are repeated.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
