Description

Pipe packaging equipment {Packaging equipment for pipe}

The present invention relates to a pipe wrapping device, and more particularly, to a pipe wrapping device capable of continuously wrapping a plurality of pipes having different outer diameters in an insulating material while simultaneously cutting them.

In general, pipes for refrigerant connecting an outdoor unit and an indoor unit of an air conditioner include a high-pressure pipe and a low-pressure pipe. The high-pressure pipe has a smaller outer diameter than the low-pressure pipe. The high-pressure pipe and the low-pressure pipe are used in a form inserted into a flexible tubular insulation. Therefore, high-pressure pipes and low-pressure pipes for air conditioners are usually sold in a form inserted into an insulating material.

In a pipe manufacturing plant, high-pressure and low-pressure pipes are cut to a certain length, manually inserted into an insulating material, and then processed into coils using a winder. In particular, embossed and foamed synthetic resins are used as insulation materials for air conditioner pipes. In addition, a high-pressure pipe and a low-pressure pipe are used in the form of insertion and packaging in pairs in one insulating material. It is desirable to reduce the loss rate by making the air conditioner piping required in the field as long as possible and reducing the residual pipe after cutting and using it several times during field work. In order to achieve this purpose, a pipe for an air conditioner is generally packaged in a length of 30 m.

On the other hand, a device for cutting a pipe used in an industrial field is composed of a die for supporting or fixing the pipe, a cutter for cutting the pipe, and a drive motor for rotating the cutter, and can be classified in various ways according to the type of the cutter. there is.

However, since burrs are generated in the conventional pipe cutting process, the cut pipe cannot be directly inserted into the insulating material. The cut pipe goes through a deburring process and is then manually inserted into the insulation. Accordingly, the time required to cut the pipe and insert it into the insulating material increases, resulting in a significant drop 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 having different outer diameters without burrs.

The follow cam 26 is installed to be elastically restored to a predetermined position when the external force is removed by being pressurized and supported by the coil spring 27 . Accordingly, the coil spring 27 is installed so that the elastic restoring force of the follow cam 26 acts outward in the radial direction of the driving 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 rotary shaft of the follow cam 26 via a bearing. A ring-shaped first knife 29 and a second knife 30 respectively cutting the first pipe 100 and the second pipe 200 are installed in the knife housing 28 . The knife housing 28 rotates eccentrically while the first knife 29 and the second knife 30 are fixed. The amount of eccentricity of the knife housing 28 varies as the amount of eccentricity of the follow cam 26 varies. Accordingly, the amount of eccentricity of the first knife 29 and the second knife 30 is also varied. The first knife 29 and the second knife 30 cut the respective pipes while being eccentrically rotated along the outer circumferential surfaces of the first pipe 100 and the second pipe 200 .

A contact surface between the follow cam 26 and the cam drum 35 is inclined with respect to the longitudinal direction of the driving shaft 24 . Accordingly, as the cam drum 35 moves forward, the amount of eccentricity of the follow cam 26 gradually increases. As the cam drum 35 moves backward, the amount of eccentricity of the follow cam 26 decreases. When the cam drum 35 moves backward to the initial position, the center of rotation of the follow cam 26 coincides with the center of rotation of the driving shaft 24 . The cam drum 35 can be moved forward and backward by a cam lever 37 moved by a pneumatic cylinder.

The first knife 29 and the second knife 30 are variablely eccentrically rotated by the knife housing 28 moving dependently on the follow cam 26, respectively, the first pipe 100 and the second knife 100. It is configured to cut from the outside of the pipe 200 to the inside.

The first clamp module 40 is disposed in front of the knife housing 28 . The first clamp module 40 is disposed on the opposite side of 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 to be cut in cooperation with the pipe support part 22 . The first clamp module 40 is configured to be moved up and down by a pneumatic cylinder, so that the first pipe 100 and the second pipe 200 that have been cut can be gripped or unfixed. 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 to 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 an insulating material 300 to be described later.

The pipe loading module 50 is a module for loading a pipe into the pipe support part 22 . The pipe loading module 50 is disposed behind the cutting module 20 in the moving direction of the pipe to be loaded. The pipe loading module 50 loads the first pipe 100 and the second pipe 200 to be cut along a belt connected to a plurality of rollers rotated by the loading motor 52 toward the pipe support part 22. do. The pipe loading module 50 is configured such that a pipe can be loaded 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 connects the first pipe 100 and the second pipe 200 wound in a coil form for cutting between a plurality of rollers arranged vertically and alternately to flatten the first pipe (100) and the second pipe (200). 100) and the second pipe 200 pass through to be flattened. A pipe guide 62 is installed at the rear of the flattening module 60 to guide the first pipe 100 and the second pipe 200 moving to the flattening module 60 along a predetermined 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 grips the front end of the insulating 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 move up and down by means of 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 wrapped pipe by inserting the pipe cut by the first knife 29 and the second knife 30 into the insulating material 300 . The inner space of the insulating material 300 loaded into the shooter module 80 is divided to correspond to the first pipe 100 and the second pipe 200, respectively. The insulating material 300 is a flexible pipe-shaped structure. The insulating 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 insulator that The insulating material 300 may be made of foamed synthetic resin. The first pipe 100 and the second pipe 200 are simultaneously inserted into the insulating material 300 by the shooter module 80 . The shooter module 80 supports the insulator 300 wound in a coil form on the insulator storage roller 90 for hundreds of meters to be loaded in a flat state. An elevating support part 82 is installed at one end of the shooter module 80 . The elevating support part 82 is movably installed at the front end of the shooter module 80 so that the front end of the warming material 300 can be moved up and down. The elevating support part 82 may be installed to be elevating by a pneumatic cylinder. The shooter module 80 may be provided with insulating material guide rollers 84 separately disposed in the vertical direction so that the two insulating materials 300 may be sequentially loaded.

The winding machine 95 is in the form of a coil in which the first pipe 100 and the second pipe 200 cut by the cutting module 20 are inserted into the insulating material 300 in the shooter module 80 and wrapped. It is a winding device with The winder 95 separates the pipe wrapped in the insulating material 300 from the second clamp module 70 so that it can be wound in a coil form. The operation of the winder 95 may be performed by a worker. While the pipe wrapped in the insulating material 300 is wound in a coil form by the winder 95, the insulating material 300 is loaded along the shooter module 80, so that the winding machine 95 operates the insulating material ( 300) automatically moves along the shooter module 80.

Operations of the aforementioned 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 operational effects of the present invention will be described in detail by taking a process of cutting, wrapping, and then winding a pair of pipes having different outer diameters using the pipe wrapping device 10 including the above-described components as an example. I'm going to do it.

First, a worker passes the warming material 300 through the shooter module 80 and passes through the elevating support part 82 and mounts it on the second clamp module 70 . The insulating material 300 is released from the storage roller disposed at one end of the shooter module 80 and mounted on the second clamp module 70 through the shooter module 80 . The holding part of the second clamp module 70 is lowered by a pneumatic cylinder to fix the front end of the insulating material 300 . The inner space of the insulator 300 is divided into two and is configured so that the first pipe 100 and the second pipe 200 can be inserted, respectively.

Now, the first pipe 100 and the second pipe 200 having different outer diameters sequentially pass through the flattening module 60 and the pipe loading module 50, and are then loaded into the pipe support part 22. do. The pipe loaded in the pipe support part 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 15 m or 30 m. In this process, the movement of the first pipe 100 and the second pipe 200 may be performed by the pipe loading module 50 . A pipe movement amount measuring sensor (not shown) is installed between the pipe loading module 50 and the cutting module 20 to measure the pipe movement amount, and the pipe loading module 50 is loaded into the cutting module 20 The pipe length can be measured in real time. The pipe movement amount measurement sensor may include an encoder having a plurality of slits arranged circularly at regular intervals. For example, based on the positions of the first knife 29 and the second knife 30, the first pipe 100 and the second pipe 200 of 30 m are loaded side by side. Accordingly, the first pipe 100 and the second pipe 200 passing through the first knife 29 and the second knife 30 are inlets of the insulating material 300 fixed by the second clamp module 70. It is inserted into the interior of the insulating material 300 through.

The holding part of the first clamp module 40 descends to fix the first pipe 100 and the second pipe 200. The drive shaft 24 is rotated 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 only rotate along the outer circumferential surfaces of the first pipe 100 and the second pipe 200, respectively, but the pipes are not cut. Now, the cam lever 37 advances in the longitudinal direction of the drive shaft 24 by means of a pneumatic cylinder. Accordingly, the cam drum 35 advances. While contact surfaces of the cam drum 35 and the follow cam 26 come into contact with each other, the follow cam 26 is moved 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 circumferential surfaces of the first pipe 100 and the second pipe 200 while rotating eccentrically. When the cam drum 35 is maximally eccentric to the follow cam 26, the cutting of the first pipe 100 and the second pipe 200 is completed.

Now, the cam lever 37 moves backward, and the cam drum 35 moves backward accordingly. As a result, while the follow cam 26 is elastically restored by the coil spring 27, the rotation centers of the follow cam 26 and the driving shaft 24 are changed to match. Accordingly, since the eccentricity of the knife housing 28 becomes 0 (zero), the first knife 29 and the second knife 30 rotate around the rotation center of the drive shaft 24 in a state restored to their initial positions. do. The rotation of the drive shaft 24 stops.

Then, the first clamp module 40 and the cutting module 20 move forward integrally. Accordingly, the first pipe 100 and the second pipe 200 exposed between the first clamp module 40 and the second clamp module 70 are fixed by the second clamp module 70 (300). ) is inserted into the interior of

Now, the holding part 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 the initial position.

Then, the holding part of the second clamp module 70 rises to release the fixing of the insulating material 300 . In that state, the second clamp module 70 moves in a direction closer to the first clamp module 40 . Accordingly, the inlet of the insulating 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 the initial position.

The worker places the inlet of the insulating material 300 on the winder 95 with the first pipe 100 and the second pipe 200 inserted. The winding machine 95 processes the pipe wrapped in the insulating material 300 into a coil form. In this process, the insulator 300 is loaded along the shooter module 80 from the insulator storage roller 90. When the pipe wrapped in the winding machine 95 is in the form of a coil and processing is finished, the operator cuts the insulating material 300. The inlet of the cut insulating material 300 is placed at the position of the second clamp module 70 . The holding part of the second clamp module 70 descends to fix the inlet of the insulating material 300 . Now, back to the initial process, the sequential process is repeated.

In this process, since two insulators 300 can be simultaneously loaded in the elevating support part 82 installed in the shooter module 80, the winding machine 95 maintains the coil shape while the pipe is inserted into the insulator 300. During processing, the insertion and cutting of the pipe may be performed by raising or lowering the elevating support unit 82 . As a result, simultaneous cutting, wrapping, and winding of a plurality of pipes can be continuously performed.

In this way, the pipe wrapping device according to the present invention cuts a plurality of pipes having different outer diameters arranged side by side at regular intervals at the same time without burrs by the cutting module, while continuously cutting the inner space into one insulating material divided. Since the pipe can be inserted, it provides an effect of remarkably improving the productivity of the pipe packaging.

In addition, the pipe wrapping apparatus according to the present invention is configured so that the cut pipes can be sequentially inserted into other insulating materials by the elevating member while the pipe inserted into the insulating material is wound by the winder, so that the cutting of the pipe and the insulating material Since insertion and winding can be performed continuously, the effect of improving the packaging productivity of the pipe more innovatively is provided.

In the above, the present invention has been described with preferred embodiments, but the present invention is not limited by such examples, and various types of embodiments may be embodied within a scope that does not depart from the technical spirit of the present invention.
