The present invention relates to an automatic resin coating device for paper tubes, and more particularly, to an automatic resin coating device for paper tubes that can improve productivity by automating the process of applying resin to both inner surfaces of the paper tubes.

Generally, a paper tube is a tube for winding papers or resin films in a roll state, and is generally manufactured by winding up a plurality of sheets of paper.

In the manufacturing process, a plurality of sheets of paper are overlapped and wound in a cylindrical shape in the manufacturing process, whereby an adhesive such as glue is used to maintain adhesive strength to each other.

Then, a drying step of drying the branch pipe proceeds, and a surface paper applying step of coating the surface paper on the outer circumference of the core by using a three-roller device is performed after the drying step. In addition, a waxing process of coating wax on the outer circumference of the paper tube surface paper, and an extrusion process of passing the paper tube through the inside of the extrusion cylinder in order to correct the roundness and surface roughness of the paper tube is sequentially performed.

Paper tubes manufactured through this process are generally supplied to the end user for secondary processing.

Then, the end user performs a chucking operation (Cucking) to wind the film by using such a tube, such chucking operation is made by fixing the tube by contacting the chucking jig on both sides of the inner tube.

In this chucking operation, since the jig comes into contact with both inner surfaces of the paper pipe, paper dust is generated on both inner surfaces of the paper pipe due to the friction. Therefore, in order to prevent the generation of dust, the paper pipe manufacturer will be shipped by coating the resin on both sides of the paper pipe.

Hereinafter, with reference to the accompanying drawings will be described in detail the automatic resin coating device of the paper pipe according to a preferred embodiment of the present invention.

1 to 3, the automatic resin coating device of the paper pipe proposed by the present invention is a housing (Housing) 1, and the support portion (3) mounted on the housing (1) to support the paper pipe (2) And coating means (5) for applying resin to both inner surfaces of the paper tube (2) seated on the support portion (3), a resin supply portion (7) for supplying resin to the coating means (5), and the paper tube ( And a control unit (not shown) for controlling the elements.

In the automatic resin coating device of the branch pipe having such a structure, the components respectively provided on both sides of the housing of the above components are the same structure and will be described by the components provided on one side.

The support portion 3 is a pair of place holders (9) for placing the branch pipe (2) in the semi-circular groove 13, and the inside of the pair of place holders (9), respectively, by the up and down reciprocating motion It consists of a moving plate 11 which sequentially moves the branch pipe 2 piled up on the mounting base 9.

The loading bases 9 are respectively located on both sides of the upper surface of the housing 1 and correspond to each other. In addition, since the semi-circular groove 13 is processed in the upper surface of the said mounting base 9, the branch pipe 2 is piled up in this groove 13, and it can be piled up stably.

In addition, the moving plate 11 has a plurality of serrated inclined surfaces 17 inclined at a predetermined angle on the upper surface thereof. And the lower part is connected to the pneumatic member 15.

Therefore, when the pneumatic member 15 is operated, the movable plate 11 is raised, and at this time, the inclined surface 17 of the movable plate 11 is raised, the branch pipe 2 which is placed on the loading base 9. Pushed the bottom of).

When the upper surface of the moving plate 11 rises to a position higher than the upper surface of the loading stand 9, the branch pipe 2 seated on the loading stand 9 rolls along the inclined surface 17 of the moving plate 11. Then, it moves to the next loading stand 9. In this way, by moving the reciprocating movement of the moving plate 11 up and down, the branch pipe 2 can be sequentially moved to the application work position.

On the other hand, the application means (5) is to apply the resin to the inner surface of both sides of the branch pipe (2) moved to the application work position by the loading base (9).

The applicator 5 includes a frame 19 disposed on both sides of the upper part of the housing 1, a pneumatic part 21 mounted on the frame 19 to generate power, and the pneumatic part 21. It consists of an application part 23 which apply | coats resin to both inner surfaces of the said branch pipe 2 by advancing back and forth in cooperation with the said.

In the application means having such a structure, the pneumatic portion 21 is a cylinder 25 mounted on one side of the frame 19 and a piston 27 mounted reciprocally in the cylinder 25. The piston 27 protrudes inward of the frame 19.

In addition, a connecting shaft 29 is provided at the front end of the piston 27, and a rotary wheel 31 is mounted at the front end of the connecting shaft 29. That is, the connecting shaft 29 is connected to the rear of the rotary wheel 31 by a bearing 28 (Fig. 4), the rotating shaft 45 is fixedly connected to the front. In addition, the rotary wheel 31 is connected to the motor assembly 35 by a belt 33.

Accordingly, when the motor assembly 35 is operated, rotational force is transmitted to the rotation wheel 31 by the belt 33, and the rotation wheel 31 is rotated.

At this time, the connecting shaft 29 is idle by being connected by the rotary wheel 31 and the bearing 28 (Fig. 4), and is also fixed by the rotation preventing key 26 and the rotary wheel 34 In the case of rotating), the connecting shaft 29 does not rotate, and only the rotating shaft 45 rotates.

Therefore, when the pneumatic part 21 is operated and the piston 27 moves forward and backward, the resin application part 23 also moves forward and backward to be inserted into or separated from the paper pipe 2.

As shown in FIGS. 3 to 5, the resin coating unit 23 includes a driving wheel 61 integrally connected to the rotation shaft 45 and a sliding movable radially on the driving wheel 61. And a resin coating roller 41 mounted on the sliding portion 43 to apply resin to both sides of the branch pipe 2 in the eccentric rotation state.

In the resin coating part having such a structure, the driving wheel 61 is rotatably connected to the tip portion of the rotation shaft 45. Therefore, when the rotating wheel 31 is rotated as it is rotated.

In addition, the sliding part 43 is slidably mounted on the base 44 fixed to the front surface of the driving wheel 61 and the base 44 in the center direction or the radial direction of the driving wheel 61. It consists of a movable sliding plate 47.

The base 44 is provided with a pneumatic supply jack 57 for supplying pneumatic to one side and a pneumatic discharge jack 59 for discharging the pneumatic. Therefore, the pneumatic pressure can be appropriately supplied through the pneumatic supply jack 57 and the pneumatic discharge jack 59.

In addition, a guide groove 51 is formed at one side of the base 44, and a leg portion (not shown) of the sliding plate 47 is coupled to the guide groove 51.

Therefore, when the pneumatic pressure is transmitted to the base 44, the sliding plate 47 can be appropriately formed with respect to the center of the drive wheel 61 by moving radially along the guide groove 51.

On the other hand, a resin coating roller 41 is integrally mounted to the sliding plate 47. That is, the resin coating roller 41 is fixedly mounted to one side of the slitting plate 47 by the fixed shaft 42.

Therefore, by appropriately moving the sliding plate 47, the resin coating roller 41 can be moved from the center of the drive wheel 61 to rotate in an eccentric state.

The resin coating roller 41 is a cylindrical roller type and is formed of a material that can easily bury the resin on its surface.

Therefore, in the state in which the resin coating roller 41 is in an eccentric state, the resin coating roller 41 is rotated together along the eccentric trajectory by contacting the inside of one side of the branch pipe 2 and by the rotation of the driving wheel 61. Resin deposited on the surface of the resin coating roller 41 is applied to the inner side surface 4 of the branch pipe 2.

In this resin coating roller 41, resin is supplied from the resin supply part 7. As shown in FIG. The resin supply unit 7 is disposed on both sides of the upper surface of the housing 1, as shown in Figs. The resin supply unit 7 is a "∪" shaped resin reservoir 71 attached to the upper surface of the housing 1, a roller 75 rotatably mounted to the resin reservoir 71, the roller 75 ), And a cylinder (76) for raising and lowering the resin reservoir (71) up and down.

In such a resin supply part, the lower part of the roller 75 is buried in resin by storing a predetermined amount of resin 73 in the said resin storage container 71.

In this state, when the coating means 5 is reversed and the resin coating roller 41 reaches the position of the roller 75, the cylinder 76 is operated to raise the resin reservoir 71, The roller 75 comes into contact with the resinous roller 41.

Therefore, the resin stored in the resin reservoir 71 is supplied to the resin coating roller 41 through the roller 75 and is applied. When the resin coating roller 41 is advanced to reach the inside of the paper tube 2, the paper tube Resin can be apply | coated to the inner side surface 4 of (2).

On the other hand, the upper pressing portion 36 is fixed to the frame 19, when the branch pipe 2 is placed on the loading base 9, it is fixed in place by pressing the branch pipe (2) from the top.

The upper pressurizing portion 36 is mounted on the cylinder 37, the piston 38 mounted inside the cylinder 37 to reciprocate up and down, and the lower end portion of the piston 38 to support the branch pipe 2. And a plate 39 to pressurize.

Therefore, the piston 38 is lowered so that the "39" shaped plate 39 presses the branch pipe 2 so that the resin coating work can be performed at the correct position. When the resin coating work is completed, the piston 38 is raised.

Hereinafter, with reference to the accompanying drawings will be described in more detail the operation of the resin automatic resin coating device of the paper pipe according to an embodiment of the present invention.

As shown in Figs. 1 to 6, when resin is applied to both ends of the branch pipe 2, the control unit (not shown) is operated by first operating a switch. The control unit drives the moving plate 11 by transmitting a signal to the support unit 3 so that the plurality of branch pipes 2 are placed on the mounting base 9.

When the accumulated paper pipe 2 moves to reach the application work position, the controller sends a signal to supply the pneumatic pressure through the pneumatic supply and discharge jacks 57 and 59 provided in the sliding part 43, thereby providing a sliding plate ( 47 so that the center of the resin roller (41) is eccentric with respect to the center of the drive wheel (61) by moving a certain distance from the center.

In this case, the eccentric operation may be performed manually or may be performed in advance before the application operation.

In this way, by operating the pneumatic portion 21 in the eccentric state, the piston 27 is advanced in the direction of the branch pipe (2). As the piston 27 advances, the connecting shaft 29 of the applicator 5 also passes through the rotary wheel 31 to advance the rotary shaft 45. As the rotating shaft 45 is advanced, the resinous roller 41 reaches the resin supply part 7. As shown in FIG.

When the resin coating roller 41 reaches the resin supply unit 7, the control unit sends a signal to operate the cylinder 76 to cause the resin reservoir 71 to rise.

At this time, the roller 75 is in a state of being rotated by the motor assembly 77, and the surface of the roller 75 is in a state of being buried. The resin reservoir 71 is raised to a predetermined position, preferably to a position where the roller 75 is in contact with the resin roller 41.

Then, the roller 75 is rotated by the motor assembly 77 to apply a resin to the resin roller (41).

When this operation is completed, the resin reservoir 71 is lowered again to return to the original position, the resin coating roller 41 is advanced to reach the inner surface 4 of the both ends of the branch pipe (2).

At this time, the resin coating roller 41 is in contact with the inner surface 4 of the branch pipe (2). In this state, the motor assembly 35 is driven so that the rotary wheel 31 rotates. The rotary shaft 45 is rotated by the rotation of the rotary wheel 31, and the resin coating roller 41 is also rotated.

At this time, since the resin coating roller 41 is eccentric with respect to the rotation center, the resin is applied while being eccentrically rotated along the inner surface 4 of the branch pipe 2.

That is, since the resin coating roller 41 is in an eccentric state, even if the diameter of the resin coating roller 41 does not have to be the same size as the inner diameter of the paper pipe 2, it has a size smaller than the inner diameter of the paper pipe 2. Since the eccentric rotation is performed, the resin can be applied to the inner side surface 4 of the branch pipe 2 efficiently.

In addition, while the rotating wheel 31 is rotating, the connecting shaft 29 is connected by the rotating wheel 31 and the bearing 28, so that the connecting shaft 29 does not rotate.

After the resin coating work is completed on the paper pipe 2, the control unit causes the resin coating roller 41 to be separated from the paper pipe 2 by reversing the piston 27.

Then, when the next branch pipe 2 reaches the application position, the resin is applied to both inner surfaces of the branch pipe 2 by repeating the above process.

As described above, the automatic resin coating device of the paper pipe according to the preferred embodiment of the present invention has an advantage of improving work efficiency and work precision by automating the resin coating work of the paper pipe.

In addition, there is an advantage that the resin coating work can be efficiently carried out by rotating the resin coating roller eccentrically.

In addition, the resin supply apparatus is provided separately to automatically supply the resin, thereby improving the work efficiency.
