Description

Packaging equipment for pipe}

The present invention relates to a pipe packaging device, and more specifically, to a pipe packaging device that can simultaneously cut a plurality of pipes with different outer diameter sizes and continuously package them in an insulating material.

Generally, refrigerant pipes connecting the outdoor unit and indoor unit of an air conditioner include high-pressure pipes and low-pressure pipes. High-pressure pipes have a smaller outer diameter than low-pressure pipes. High-pressure piping and low-pressure piping are used inserted into flexible tubular insulation. Therefore, high-pressure piping and low-pressure piping for air conditioners are usually sold in a form inserted into insulation material.

At pipe production plants, high-pressure pipes and low-pressure pipes are cut to a certain length, inserted into insulation materials by hand, and then processed into coils using a winder. In particular, embossed and foamed synthetic resin is used as insulation material for air conditioner piping. In addition, a pair of high-pressure pipes and low-pressure pipes are inserted and packaged into one insulating material. It is advisable to make the air conditioner piping required in the field as long as possible and reduce the loss rate by reducing the amount of leftover pipe after cutting and using it several times during field work. To achieve this purpose, piping for air conditioners is generally preferred to be packaged at a length of 30 m.

Meanwhile, a device for cutting pipes used in industrial sites consists of a die that supports or fixes the pipe, a cutter that cuts the pipe, and a drive motor that rotates the cutter, and can be classified into various types depending on the type of cutter. there is.

However, since burrs are generated in the conventional pipe cutting process, the cut pipe cannot be directly inserted into the insulation material. The cut pipe goes through a burr removal process and is then manually inserted into the insulation material. Accordingly, the time required to cut the pipe and insert it into the insulating material increases, causing a significant decrease in productivity.

In addition, the conventional pipe cutting process has a problem in that it is very difficult to simultaneously cut a plurality of pipes with different outer diameters without burrs.

Referring to Figures 1 to 8, the pipe packaging device 10 according to the present invention is a device that can simultaneously cut a plurality of pipes with different outer diameter sizes and package them in the insulation material 300.

The pipe packaging device 10 includes a cutting module 20, a first clamp module 40, a pipe loading module 50, a flattening module 60, a second clamp module 70, and a shooter module. It includes (80) and a winder (95).

The cutting module 20 is a module that simultaneously cuts a plurality of pipes arranged in close proximity to each other. In this embodiment, the cutting module 20 is configured to cut two pipes simultaneously. A characteristic feature is that the outer diameters of the plurality of pipes cut by the cutting module 20 are different from each other. The cutting module 20 is installed on the base 15 supported on the ground so that it can reciprocate within a certain range along the direction in which the pipe is moved.

The cutting module 20 includes a pipe support portion 22, a drive shaft 24, a follow cam 26, a knife housing 28, a cam drum 35, a first knife 29, and a first knife 29. Includes 2 knives (30).

The pipe support portion 22 clamps a plurality of pipes with different outer diameters so that they are adjacent to each other in order to cut them. The pipe support portion 22 is provided with a pipe penetration hole so that a plurality of pipes can pass through it in parallel. The pipe penetration holes are provided separately so that each pipe can pass through them independently. In this embodiment, the pipe support portion 22 supports the first pipe 100 and the second pipe 200, which has an outer diameter different from the first pipe 100, in a parallel and spaced apart state.

The drive shaft 24 is disposed on the side of the pipe support portion 22. The drive shaft 24 is installed so that it can rotate. In this embodiment, the drive shaft 24 is installed on both sides of the pipe support portion 22 and rotates at the same speed. The drive shaft 24 is connected to a pulley with a belt by one drive motor 23. can be rotated at the same speed.

The follow cam 26 is disposed at the front end of the drive shaft 24. The follow cam 26 is installed to variably adjust the amount of eccentricity with respect to the central axis of the drive shaft 24. The follow cam 26 is pressurized and supported by the coil spring 27, so that it is elastically restored to a certain position when external force is removed. Accordingly, the coil spring 27 is installed so that the follow cam 26 exerts an elastic restoring force on the radial outer side of the drive shaft. The coil spring 27 may be a compression coil spring.

The knife housing 28 is disposed in front of the follow cam 26. The knife housing 28 is installed on the rotation axis of the follow cam 26 via a bearing. A ring-shaped first knife 29 and a second knife 30 are installed in the knife housing 28 to cut the first pipe 100 and the second pipe 200, respectively. The knife housing 28 is rotated eccentrically while fixing the first knife 29 and the second knife 30. The eccentricity of the knife housing 28 varies as the eccentricity of the follow cam 26 varies. Accordingly, the amount of eccentricity of the first knife 29 and the second knife 30 also varies. The first knife 29 and the second knife 30 rotate eccentrically along the outer peripheral surfaces of the first pipe 100 and the second pipe 200 to cut each pipe.

The cam drum 35 is installed to reciprocate in the longitudinal direction of the drive shaft 24. The cam drum 35 is provided to vary the amount of eccentricity of the follow cam 26. The contact surface of the follow cam 26 and the cam drum 35 is inclined with respect to the longitudinal direction of the drive shaft 24. Accordingly, as the cam drum 35 advances, the eccentricity of the follow cam 26 gradually increases. As the cam drum 35 moves backward, the eccentricity of the follow cam 26 decreases. When the cam drum 35 moves backwards to its initial position, the rotation center of the follow cam 26 coincides with the rotation center of the drive shaft 24. The cam drum 35 can move forward and backward by the cam lever 37 moved by a pneumatic cylinder.

The first knife 29 and the second knife 30 are rotated with variable eccentricity by the knife housing 28 that moves dependently on the follow cam 26, and the first pipe 100 and the second knife 30 are rotated with variable eccentricity, respectively. It is configured to cut the pipe 200 from the outside to the inside.

The first clamp module 40 is disposed in front of the knife housing 28. The first clamp module 40 is disposed opposite the pipe support part 22 with the knife housing 28 interposed therebetween. That is, the first clamp module 40 firmly supports both sides of the cut portions of the first pipe 100 and the second pipe 200 in cooperation with the pipe support portion 22. The first clamp module 40 is configured to be raised and lowered by a pneumatic cylinder, so that it can grip or unfasten the cut first pipe 100 and second pipe 200. The first clamp module 40 is installed to be movable in the longitudinal direction of the drive shaft 24. In addition, the first clamp module 40 is physically connected to the cutting module 20 and is installed so that it can move forward or backward together. The first clamp module 40 moves forward in the process of wrapping the cut ends of the first pipe 100 and the second pipe 200 in the insulation material 300, which will be described later.

The pipe loading module 50 is a module that loads pipes into the pipe support unit 22. The pipe loading module 50 is disposed behind the cutting module 20 in the direction of movement of the pipe being loaded. The pipe loading module 50 loads the first pipe 100 and the second pipe 200 to be cut toward the pipe support unit 22 along a belt connected to a plurality of rollers rotated by the loading motor 52. do. The pipe loading module 50 is configured to load pipes between rollers arranged vertically.

The flattening module 60 is a module that flattens the uncoiled pipe supplied to the pipe loading module 50. The flattening module 60 moves the first pipe (100) and the second pipe (200) wound in a coiled shape between a plurality of rollers arranged vertically to form a flat surface for cutting. 100) and the second pipe 200 are smoothed as they pass through. A piping guide 62 is installed at the rear of the flattening module 60 to guide the first pipe 100 and the second pipe 200, which are moved to the flattening module 60, to move along a certain path. .

The second clamp module 70 is disposed in front of the first clamp module 40. The second clamp module 70 is movably installed on the base 15. The second clamp module 70 is installed to be movable within a certain range in the longitudinal direction of the drive shaft 24. The second clamp module 70 holds the tip of the insulation material 300 into which the first pipe 100 and the second pipe 200 are simultaneously inserted. The second clamp module 70 is installed so that the holding part can be raised and lowered by a pneumatic cylinder. The second clamp module 70 is installed to be movable in the longitudinal direction of the drive shaft 24 independently of the first clamp module 40.

The shooter module 80 is a module that manufactures a packaged pipe by inserting the pipe cut by the first knife 29 and the second knife 30 into the insulation material 300. The insulation material 300 loaded into the shooter module 80 is divided into internal spaces corresponding to the first pipe 100 and the second pipe 200, respectively. The insulation material 300 is a flexible pipe-shaped structure. The insulation material 300 surrounds and protects the outside of the first pipe 100 and the second pipe 200 and prevents the refrigerant flowing inside the first pipe 100 and the second pipe 200 from exchanging heat with the atmosphere. It is an insulating material that The thermal insulation material 300 may be made of foamed synthetic resin. The first pipe 100 and the second pipe 200 are simultaneously inserted into the insulation material 300 by the shooter module 80. The shooter module 80 supports the insulation material 300, which is wound in the form of a coil for several hundred meters, on the insulation storage roller 90 so that it is loaded in a flat state. A lifting support part 82 is installed at one end of the shooter module 80. The lifting support unit 82 is installed to be capable of being raised and lowered at the front end of the shooter module 80 so as to raise and lower the front end of the insulation material 300. The lifting support unit 82 may be installed to be lifted up and down by a pneumatic cylinder. The shooter module 80 may be provided with insulation guide rollers 84 arranged separately in the vertical direction so that the two insulation materials 300 can be sequentially loaded.

The winder 95 is formed in a coiled state in which the first pipe 100 and the second pipe 200 cut by the cutting module 20 are inserted into the insulation material 300 in the shooter module 80 and packaged. It is a winding device. The winder 95 separates the pipe wrapped in the insulation material 300 from the second clamp module 70 and allows it to be wound in the form of a coil. The operation of the winder 95 may be performed by an operator. While the pipe wrapped in the insulation material 300 is wound into a coil by the winder 95, the insulation material 300 is loaded along the shooter module 80, thereby forming the insulation material ( 300) automatically moves along the shooter module 80.

Operation of the above-described cutting module 20, first clamp module 40, pipe loading module 50, flattening module 60, second clamp module 70, shooter module 80, and winder 95. Can be controlled by an integrated controller. The controller may include a touch panel.

Hereinafter, the effects of the present invention will be described in detail, taking as an example the process of cutting, packaging, and then winding a pair of pipes with different outer diameters using the pipe packaging device 10 including the components described above. I decided to do it.
The process of cutting, packaging, and winding a pair of pipes with different outer diameter sizes largely consists of four steps (first process, second process, third process, and fourth process). As a first process, this is a step in which the insulation material 300 is prepared to wrap the pipe by the shooter module 80 and the second clamp module 70.

First, an operator places the insulation material 300 on the second clamp module 70 through the lifting supporter 82 through the shooter module 80. The insulation material 300 is released from the storage roller disposed at one end of the shooter module 80 and placed on the second clamp module 70 through the shooter module 80. The second clamp module 70 fixes the front end of the insulation material 300 by lowering the grip portion by a pneumatic cylinder. The internal space of the insulation material 300 is divided into two so that the first pipe 100 and the second pipe 200 can be inserted, respectively. (1st process)

Now, the first pipe 100 and the second pipe 200, which have different outer diameters, sequentially pass through the flattening module 60 and the pipe loading module 50 and then are loaded into the pipe support unit 22. do. During this process, the first clamp module 40 maintains the first pipe 100 and the second pipe 200 in a state in which it does not grip the first pipe 100 and the second pipe 200. The pipe loaded on the pipe support portion 22 advances further by the length to be cut based on the first knife 29 and the second knife 30. For example, the pipe advances 15m or 30m. In this process, the first pipe 100 and the second pipe 200 may be moved by the pipe loading module 50. A pipe movement amount measurement sensor (not shown) is installed between the pipe loading module 50 and the cutting module 20 to measure the movement amount of the pipe, so that the pipe is loaded from the pipe loading module 50 to the cutting module 20. The length of the pipe can be measured in real time. The pipe movement amount measurement sensor may include an encoder having a plurality of slits arranged in a circle at regular intervals. For example, 30 m of the first pipe 100 and the second pipe 200 are loaded in parallel based on the positions of the first knife 29 and the second knife 30. Accordingly, the first pipe 100 and the second pipe 200 that passed through the first knife 29 and the second knife 30 are connected to the inlet of the insulation material 300 fixed by the second clamp module 70. It is inserted into the interior of the insulation material 300 through (second process). While the second process is performed, the first pipe 100 and the second pipe 200 are not cut and the insulation material is removed by the pipe loading module 50. Advance towards (300). In this process, the first clamp module 40 and the cutting module 20 do not grip or cut the first pipe 100 and the second pipe 200.

Now, as a third process, the first pipe 100 and the second pipe 200 are cut. The gripping part of the first clamp module 40 descends and fixes the first pipe 100 and the second pipe 200. The drive shaft 24 rotates by the drive motor 23. As the drive shaft 24 rotates, the follow cam 26 rotates. As the follow cam 26 rotates, the knife housing 28 rotates. As the knife housing 28 rotates, the first knife 29 and the second knife 30 rotate. In this process, the first knife 29 and the second knife 30 rotate along the outer peripheral surfaces of the first pipe 100 and the second pipe 200, respectively, but the pipes are not cut. Now, the cam lever 37 is advanced in the longitudinal direction of the drive shaft 24 by the pneumatic cylinder. Accordingly, the cam drum 35 advances. As the contact surfaces of the cam drum 35 and the follow cam 26 contact each other, the follow cam 26 moves in the radial direction of the drive shaft 24 by the cam drum 35. Accordingly, the knife housing 28 is rotated eccentrically. As a result, the first knife 29 and the second knife 30 cut the outer peripheral surfaces of the first pipe 100 and the second pipe 200 while rotating eccentrically, respectively. When the cam drum 35 eccentricizes the follow cam 26 to the maximum, cutting of the first pipe 100 and the second pipe 200 is completed.

Now, the cam lever 37 retracts, and the cam drum 35 accordingly retracts. As a result, the follow cam 26 is elastically restored by the coil spring 27, and the rotation centers of the follow cam 26 and the drive shaft 24 are changed to coincide. Accordingly, the eccentricity of the knife housing 28 becomes 0 (zero), so the first knife 29 and the second knife 30 rotate around the rotation center of the drive shaft 24 in a state restored to the initial position. do. The rotation of the drive shaft 24 stops. (3rd process)

And, as a fourth process, a process of inserting the ends of the first pipe 100 and the second pipe 200 cut in the third process into the insulation material 300 is performed. That is, the first clamp module 40 and the cutting module 20 advance as one unit. Accordingly, the first pipe 100 and the second pipe 200 exposed between the first clamp module 40 and the second clamp module 70 are connected to the insulation material 300 fixed by the second clamp module 70. ) is inserted into the inside of (4th process)

Now, the gripping portion of the first clamp module 40 rises to release the fixation of the pipe. Then, the first clamp module 40 and the cutting module 20 move backward to their initial positions.

Then, the holding portion of the second clamp module 70 rises to release the fixation of the insulation material 300. In that state, the second clamp module 70 moves in a direction closer to the first clamp module 40. Accordingly, the inlet portion of the insulation material 300 into which the first pipe 100 and the second pipe 200 are inserted is separated from the second clamp module 70. The second clamp module 70 moves back to its initial position. (Reset process)

The worker places the inlet part of the insulation material 300 on the winder 95 with the first pipe 100 and the second pipe 200 inserted. The winder 95 processes the pipe wrapped in the insulation material 300 into a coil shape. In this process, the insulation material 300 is loaded from the insulation storage roller 90 along the shooter module 80. When the pipe packed in the winder 95 is processed into a coil shape, the worker cuts the insulation material 300. The inlet of the cut insulation material 300 is placed at the location of the second clamp module 70. The grip portion of the second clamp module 70 descends and fixes the inlet of the insulation material 300. Now, going back to the initial process, the sequential process is repeated.

In this process, two insulation materials 300 can be loaded simultaneously on the lifting support unit 82 installed on the shooter module 80, so that the pipe is inserted into the insulation material 300 by the winder 95 and is in the form of a coil. During processing, pipe insertion and cutting operations can be performed by raising or lowering the lifting support unit 82. As a result, simultaneous cutting, packaging and winding of multiple pipes can be performed continuously.

In this way, the pipe packaging device according to the present invention simultaneously cuts a plurality of pipes with different sizes of outer diameters arranged side by side at regular intervals without burrs by means of a cutting module, and continuously forms a single insulation material with a divided internal space. Since pipes can be inserted, it provides the effect of significantly improving pipe packaging productivity.

In addition, the piping packaging device according to the present invention is configured so that the cut piping can be sequentially inserted into another insulating material by a lifting member while the piping inserted into the insulating material is wound by a winder, so that the piping is cut and the insulating material is Since insertion and winding can be done continuously, it provides the effect of further innovatively improving the packaging productivity of pipes.
