2 to 11, the present invention is a tube cutting method for supplying the tube T loaded in the supply unit 2000 to the cutting unit 1000 to cut the tube T by a specified length. As described, the supply unit 2000 has a space so that one tube T to be processed next can wait while cutting the tube T by a predetermined length in the cutting unit 1000 When the preliminary settling unit 2100 and the tube T waiting in the preliminary settling unit 2100 move to the cutting device unit 1000, a plurality of tubes T are supplied to the preliminary settling unit 2100. The tube (T) of the loading portion 2200; consists of.

Accordingly, after the process of cutting the tube T in the cutting device unit 1000 is finished, the tube T in the preliminary settling unit 2100 is supplied to the cutting unit 1000, and the preliminary settling unit 2100 It describes a tube cutting method in which a process in which any one of the plurality of tubes T loaded in the loading part 2200 is supplied to the preliminary settling part 2100 is repeated.

For reference, the cutting device unit 1000 of the present application refers to the contents of Korean Patent Registration No. 0505289 described above, and the same reference numerals are used so as not to confuse some of the components introduced.

In more detail, in the preliminary settling part 2100 of the present invention, a tube T on the opposite side of the channel 115 based on the blocks 24 and 25 in which the chamber 60 for a cutting mechanism is secured is inside. A hexahedral casing 2110 in which a space portion that can be placed is formed but the side portion in the longitudinal direction and one surface facing the blocks 24 and 25 is opened, and the inside of the casing 2110 at the end of the casing 2110 It consists of a pushing frame 2120 installed to move along the longitudinal direction.

Accordingly, the tube T is supplied into the casing 2110 through the opening formed on the side of the casing 2110 in the longitudinal direction, and when the cutting operation of the tube T is finished in the cutting device unit 1000, the The pushing frame 2120 pushes the tube T while linearly moving inside the casing 2110 to supply the tube T into the channel 115 formed on the other side of the blocks 24 and 25.

In addition, a plurality of support blocks 2130 for supporting each tube T to maintain a predetermined space from the bottom surface of the casing 2110 are mounted at predetermined intervals on the bottom surfaces of both inner ends of the casing 2110, Among the support blocks 2130, a roller 2131 is mounted on the upper surface of the support block 2130, which is close to the chamber 60, so that the tube T that moves linearly with the pushing frame 2120 can move more smoothly. I made it easy.

On one side of the opening formed on the side of the casing 2110 in the longitudinal direction, a loading part 2200 in which a tube T for supplying the tube T into the casing 2110 through the opening is installed. , The loading part 2200 is provided with a primary support frame 2210 supporting the lower surface of the tube T so that a plurality of tubes T are aligned in parallel in the longitudinal direction of the casing 2110. .

On the other hand, the primary support frame 2210 is formed to be inclined downward toward the casing 2110 so that the tubes T aligned in parallel with the primary support frame 2211 will naturally roll into the interior of the casing 2110. The first support frame 2211 has a stopper 2211 protruding from the end side of the first support frame 2211 to control the tube T from rolling into the casing 2110.

Since the operation and control method of the stopper 2211 is a well-known technique, detailed description will be omitted.

In particular, at the end of the primary support frame 2210, a secondary support frame 2220 in the form of a concave groove with an open top is formed to have a space in which a plurality of tubes T are stacked in the upper direction. .

Further, a roller 2221 is formed between the primary support frame 2210 and the secondary support frame 2220, and a belt 2222 is mounted along the upper surface of the secondary support frame 2220, so that the belt 2222 A plurality of tubes (T) are stacked on the upper surface of ).

In addition, one end of the belt 2222 is fixed to the end of the secondary support frame 2220, and the other end of the belt 2222 passes through the upper surface of the roller 2221 to the lower side of the secondary support frame 2220. It is wound on a configured drum.

Accordingly, when the drum rotates, one end of the belt 2222 is fixed to the end of the secondary support frame 2220, so when the belt 2222 is wound around the drum, the belt 2222 becomes taut and the tube (T) rises, and when the tube (T) rises above the roller (2221), the tube (T) on the side of the roller (2221) among the plurality of stacked tubes (T) naturally rides the roller (2221). It rolls over to the primary support frame 2210.

Among both ends of the secondary support frame 2220, which is concavely formed so that the belt 2222 remaining without being wound on the drum is inclined downward toward the roller 2221, the end of the belt 2222 is fixed. It would be desirable to be formed relatively high.

That is, the tube (T) stacked on the secondary support frame 2220 does not deviate to the outside and can naturally go toward the primary support frame 2210.

On the other hand, in order to stably supply one tube (T) to the primary support frame 2210 between the primary support frame 2210 and the roller 2221 of the secondary support frame 2220, 3 The vehicle support frame 2230 is formed.

A rotation frame 2231 that rotates toward the primary support frame 2210 is mounted on the V-groove-shaped third support frame 2230.

Accordingly, one of the plurality of tubes T stacked on the secondary support frame 2220 is moved to the V groove of the third support frame 2230, and is in the V groove of the third support frame 2230. The tube (T) that was located is naturally moved to the primary support frame (2210) as the rotation frame (2231) rotates.

The operation of supplying the tube (T) placed on the tertiary support frame 2230 to the primary support frame 2210 by rotating the pivoting frame 2231 to the primary support frame 2210 is a well-known means of use. Since it can be configured as a detailed description will be omitted.

As described above, if the tube cutting method of the present invention is briefly summarized, when the cutting operation of the tube T in the cutting device unit 1000 is completed, the tube T that was placed in the casing 2110 of the preliminary setting unit 2100 ) Is supplied to the cutting device unit 1000 by the pushing frame 2120.

When it is detected that there is no tube (T) in the casing 2110 of the spare device unit 2100, the stopper 2211 of the primary support frame 2210 is operated to operate the tube placed on the primary support frame 2210 ( T) is moved into the casing 2110 of the spare device unit 2100.

And when one of the plurality of tubes (T) placed on the primary support frame (2210) moves into the casing (2110) of the spare unit (2100), the tube in which the V groove of the tertiary support frame (2230) is seated. (T) is moved to the primary support frame 2210 by the rotating frame 2231.

Finally, when it is detected that there is no tube (T) in the V groove of the third support frame 2230, the drum 2223 operates to wind the belt 2222, and the belt 2222 is wound around the drum 2223. As the belt 2222 in a loose state gradually becomes taut and maintains an inclined state toward the third support frame 2230, one of the tubes T that rises together with the belt 2222 becomes the third support frame 2230 ), and when one of the tubes (T) is placed on the third support frame 2230, the drum 2223 rotates in the opposite direction to release the belt 2222 wound around the drum 22230. The tube T, which was raised together, is seated inside the secondary support frame 2220.

12 is a plan schematic view of a supply device unit according to another embodiment of the tube cutting device according to the present invention, and FIG. 13 is a plan schematic view in which a tube is placed in a supply device unit according to another embodiment of the tube cutting device according to the present invention. 14 is a schematic side view of a supply device according to another embodiment of the tube cutting device according to the present invention, and FIG. 15 is a third support frame mounted on the supply device according to another embodiment of the tube cutting device according to the present invention. Figure 16 is a schematic view showing the operation relationship of the roller and the central axis mounted in the supply unit according to another embodiment of the tube cutting device according to the present invention.

As shown in FIGS. 12 to 16, a plurality of primary support frames 2210 are arranged, and a plurality of primary support frames 2210 are arranged at regular intervals along the longitudinal direction of the tube T. However, it is formed to be inclined downward toward the casing 2110.

Preferably, the inclination of the primary support frame 2210 is formed to maintain the tangential direction of the roller 2221.

The third support frame 2230 so that the tube T loaded in the second support frame 2220 on the side of the first support frame 2210 is not directly supplied to the inside of the casing 2110 and can wait for a while. Should be placed.

The upper end of the third support frame 2230 should be installed so as to protrude upward rather than the first support frame 2210 in order for the tube T that has passed over the roller 2221 by the drive of the belt 2222 to wait for a while. will be.

In order to firmly support the load of the tube T, it will be a more preferable implementation to be installed on the left and right sides of the primary support frame 2210, respectively.

And inside of the secondary support frame 2220, a plurality of settling frames 2224 formed long in a direction orthogonal to the tube T are arranged so as to be spaced at regular intervals along the length direction of the tube T, and the settling frame ( It is arranged so that the tube (T) can be placed on the upper surface of 2224, and the belt 2222 can be placed in the space between the placing frames 2224.

This prevents the belt 2222 wrapped in the tube T loaded inside the secondary support frame 2220 from being damaged or deformed by hitting the floor when descending by the driving of the drum 2223. Since the belt 2222 is not pressed against the load of the tube T due to the gap formed between the 2222 and the tube T, it is stored so that overload does not occur during the initial operation of the belt 2222 due to the lifting and lowering. This is to ensure that natural lifting and lowering movements occur.

In particular, the roller 2221 has a cylindrical body 2221a to which the belt 2222 comes into contact, so as not to interfere with the operation of the belt 2222 when the tube T crosses the outer periphery of the roller 2221. Flanges 2221b having a relatively larger diameter than the cylindrical body 2221a are formed at both ends of the cylindrical body 2221a so that the belt 2222 is not separated from the 2221a.

In order to supply the tube (T) of a large load, a plurality of the rollers 2221 are arranged at regular intervals in the longitudinal direction of the tube (T), and the central axis ( By fastening 2225 to pass through all the center of the tube T, the central shaft 2225 is driven by a motor (not shown).

Accordingly, when the tube T passes over the roller 2221, the tube T does not directly contact the cylindrical body 2221a, but directly contacts the flange 2221b having a larger diameter than the cylindrical body 2221a.

In addition, on one side of the third support frame 2220, a rotation frame 2231 for re-progressing the tube T, which has been waiting for a while, is installed on the third support frame 2220.

The rotating frame 2231 according to another embodiment will be described in detail below.

On the other hand, by adjusting the speed supplied from the secondary support frame 2220 to the casing 2110 according to the diameter of the tube T to be cut, the tube cutting apparatus of the present invention can cut tubes of various diameters. You can also do it.

As shown in Figs. 14 to 15, the third support frame 2230 is composed of a block body 2230a that directly contacts the tube T, and a cylinder 2230b that moves the block body 2230a up and down. By making it possible to move up and down, the height is adjusted according to the diameter of the tube (T) or is supplied from the secondary support frame 2220 to the primary support frame 2220 immediately without waiting at the third support frame 2230. Wait is to be supplied from the primary support frame 2210 to the interior of the casing 2110.

At this time, the cylinder 2230b uses hydraulic pressure.

And the block body (2230a) is formed in a triangular shape, but the inclined surface against the progress of the tube (T) is formed as a steep slope to act as a stopper, and the inclined surface of the other side is the casing 2110 by the rotating frame 2231 In order to serve as a guide for the tube (T) that proceeds to gradually roll and proceed, a gentle slope is formed.

17 is a schematic diagram showing an operation relationship of a rotating frame mounted on a supply device according to another embodiment of the tube cutting device according to the present invention.

As shown in FIG. 17, the rotating frame 2231 has an overall shape formed in a'b' shape consisting of a horizontal end and a vertical end, but is mounted so that the vertical end faces the direction in which the tube T travels.

At the end of the horizontal end, a first hinge shaft 2231a protrudes in the longitudinal direction of the tube T, and a second hinge shaft 2231b protrudes in the longitudinal direction of the tube T at the end of the vertical end. Is formed.

Accordingly, the first hinge shaft 2231a formed at the end of the horizontal end is hinged to a common bracket (not shown), so that the rotation frame 2231 can be rotated vertically.

An auxiliary rotating frame 2232 is installed as a driving means for rotating the rotating frame 2231 up and down, and the auxiliary rotating frame 2232 has a long rod shape and is arranged long in the traveling direction of the tube T. However, in the body of the tube (T), a long hole (2232b) penetrating in the left and right direction is formed long along the length of the auxiliary rotation frame (2232), and the second support is in a direction opposite to the direction in which the tube (T) travels. It is characterized in that a rotation shaft 2232a protruding in the left and right direction is formed at an end of the auxiliary rotation frame 2232 adjacent to the frame 2220.

In addition, the second hinge shaft 2231b of the rotating frame 2231 is inserted so as not to be separated from the long hole 2232b of the auxiliary rotating frame 2232.

Accordingly, when the auxiliary rotating frame 2232 is rotated in the direction A around the rotating shaft 2232a, the second hinge shaft 2231b of the rotating frame 2231 is inserted into the long hole 2232b of the auxiliary rotating frame 2232 to be fastened. As a result, the rotating frame 2231 can rotate in the B direction.

Therefore, the tube T positioned at the horizontal end of the rotating frame 2231 can proceed toward the casing 2110 of the preliminary settling part 2100 by the rotating frame 2231.

In particular, by forming a concave groove (2231c) on the upper end of the horizontal end, the cylindrical tube (T) can be seated more stably.
