And FIG. 7 is a view showing a state in which the sliding part is removed in FIG.

The head part 20 may be installed on one side of the base 10 and may have a cylindrical shape. The head portion 20 may be formed with an opening 21 having a part of the outer peripheral surface thereof opened. The head portion 20 is inserted into the coil 1 to press the inner surface of the coil 1 and can be inserted into the coil 1 as the base 10 moves. That is, the head portion 20 can reciprocate along the inner surface of the coil 1. The head portion 20 may include a rotatable center axis (not shown), but the description of the central axis will be omitted for the sake of convenience.

The rail 100 may be spirally shaped to converge toward the virtual center axis of the head portion 20 or the virtual center axis of the coil 1 (see FIGS. 6 and 7).

The pressing portion 200 can be moved away from the virtual center axis of the head portion 20 as the rail 100 rotates in one direction. That is, the pressing portion 200 can press the inner surface of the coil 1 while expanding radially outward from the imaginary center axis of the head portion 20. [

The pressing portion 200 may include a roller portion 210, a sliding portion 220, and a pressing body 230.

The roller portion 210 may be disposed on the rail 100. The roller unit 210 is disposed in a space between the spiral rails 100. The roller unit 210 can be rotated and moved by receiving the rotational force when the rail 100 rotates on the rail 100. [

The sliding portion 220 may be connected at one end to the roller portion 210 and at the other end to extend outward from the point where the rail 100 is converged. The sliding portion 220 may be disposed parallel to the surface on which the rail 100 is disposed and the other end may be bent so that the pressing body 230 and the brush portion 400 described later may be disposed. Accordingly, when the roller unit 210 rotates and moves, the sliding unit 220 can slide along the diameter of the rail 100.

The sliding portion 220 may be formed with a protrusion 221 on the rear side with respect to a direction in which the head portion 20 enters the coil 1. The protrusion 221 can be inserted into the groove 310 of the support portion 300 described later.

The pressing body 230 may be connected to the other end of the sliding portion 220 and may be pressed toward the inner side of the coil.

The outer surface of the pressing portion 200, that is, the outer surface of the pressing body 230 may face the inner surface of the coil 1. [ The wrapping paper is positioned between the outer surface of the pressing body 230 and the inner surface of the coil 1 so that the outer surface of the pressing body 230 can be pressed so that the wrapping paper is in close contact with the inner surface of the coil 1. [ have. At this time, the outer surface of the pressing body 230 may be the same as the curvature of the inner surface of the coil 1, and may be formed into a curved surface having a smaller curvature. The outer surfaces of the plurality of pressing bodies 230 may form a circle when the pressing portion 200 is maximally dislocated to the center of the rail 100, that is, when the plurality of pressing bodies 230 are in contact with each other.

Meanwhile, the automatic in-core packaging apparatus for sealing a coil wrapping paper according to an embodiment of the present invention includes a control unit (not shown) for stopping the rotation of the rail 100 when a plurality of neighboring pressing units 200 are brought into contact with each other .

8 is a view showing a supporting part and a sliding part of the automatic in-order packaging device for sealing a coil wrapping paper according to an embodiment of the present invention.

Referring to FIG. 8, the head portion 20 may further include a support portion 300. The support part 300 is disposed on one side of the sliding part 220 to support the sliding part. That is, by the rotation of the center shaft (not shown) and the rail 100, the sliding portion 220 is moved toward the outer side of the head portion 20 along the diameter of the head portion 20 or the rail 100 The support part 300 may be installed outside the head part so that the sliding part 220 is not twisted.

The support portion 300 may have a groove 310 and the protrusion 221 of the sliding portion 220 may be inserted. The groove 310 and the protrusion 221 have a shape corresponding to each other and have a length along the radial direction from a virtual center axis of the head portion 20. The sliding portion 220 slides along the longitudinal direction of the groove 310, can do. That is, since the supporting portion 300 is fixed to the head portion 20, the pressing portion 200 moves along the longitudinal direction of the groove 310, because the pressing portion 200 is radially moved as the rail 100 rotates. It is slidable.

The head portion 20 may include a brush portion 400. The brush part 400 may be disposed at one side of the other end of the sliding part 220, that is, at the sliding part 220 between the protrusion 221 and the pressing body 230. The brush part 400 may be arranged as a brush or a maneuver which is spread radially from the imaginary central axis of the head part 20. [ The brush portion 400 may have a length such that the end portion is located between the inner side surface and the outer side surface of the coil 1. That is, when the head portion 20 is inserted and slid inside the coil 1, the wrapping paper located inside the coil 1 is wiped off, and the wrapping paper is brought into close contact with the inner surface of the coil 1. The brush part 400 may be formed of a material that can be bent when the head part 20 is inserted into the coil 1 but can be restored to its original shape when the insertion is released. For example, the brush portion 400 may have elasticity.

It is preferable that the brush part 400 is disposed on the rear side of the pressing body 230 with respect to the direction in which the head part 20 enters the inside of the coil 1. [ When the head portion 20 enters the inside of the coil 1, the brush portion 400 is bent in the opposite direction to the entry, so that the movement of the pressing portion 200 radially spreading is not disturbed.

2 to 5, the attachment part 500 may be provided on the head part 20 to tap the wrapping paper closely attached to the inner side surface of the coil 1. [

The attaching portion 500 can be exposed to the outside by the opening portion 21 of the head portion 20 and can also protrude to the outside through the opening portion 21. [ The mounting portion 500 rotates inside the coil 1 while the pressing portion 200 presses the wrapping paper located on the inner side of the coil 1 toward the inner side surface of the coil 1, The tape can be attached to the wrapping paper placed on the inner side of the coil 1.

The attachment portion 500 may include a tapered roller portion 510, a first attachment portion 520, a second attachment portion 530, and a cut portion 540.

The tape roller portion 510 is wound with a tape (not shown) and is rotatable.

Referring to FIGS. 4 and 5, the first attachment portion 520 may be disposed on the lower side of the tapered roller portion 510, that is, on the rear side of the tapered roller portion 510 with respect to the rotation direction. The first attachment portion 520 may include a roller 521 and a rod 522. The roller 521 of the first attachment portion 520 is slid while the roller 521 is moved to the outside of the opening portion 21. That is, the first attachment portion 520 pushes the tape, which is fed from the tapping roller portion 510, to the outside and attaches the wrapping paper on the inner side of the coil 1.

A supporting roller (not shown) is provided between the tapering roller portion 510 and the first attachment portion 520 and the tapered roller portion 510 and the first attachment portion 520 are connected to each other, Lt; RTI ID = 0.0 > a < / RTI > The supporting roller interlocks with the first attaching portion 520 and can simultaneously slide to the outside and the inside of the opening portion 21 along the sliding of the first attaching portion 520. [

The second attachment portion 530 may be disposed relatively lower than the first attachment portion 520. In other words, the second attachment portion 530 may be disposed on the rear side of the first attachment portion 520 with respect to the rotation direction of the first attachment portion 520. The second attachment portion 530 may include a roller 531 and a rod 532. The roller 531 is moved to the outside of the opening 21 and protrudes while the rod 532 of the second attachment portion 530 slides. It is preferable that the rotation trajectory of the end of the second attachment portion 530 coincides with the rotation trajectory of the end of the first attachment portion 520. [ In other words, the second attachment portion 530 can more reliably attach the tape by once again pressing the tape attached to the first attachment portion 520 toward the inner surface of the coil 1. [ A plurality of second attachment portions 530 may be provided according to the manufacturer's intention and each end of the plurality of second attachment portions 530 may be the same as the rotation orbit of the end of the first attachment portion 520 . The second attachment portion 530 can slide at the same time as the first attachment portion 520 to the outside or inside of the opening portion 21 at the same time.

The cut portion 540 may be disposed between the first attachment portion 520 and the second attachment portion 530 so as to be exposed to the outside through the opening portion 21. The cut portion 540 can cut between the tape attached to the wrapping paper and the tape fed from the taping roller portion 510. [

The cutting portion 540 may include a cutting support portion 541 and a cutter portion 543 and the cutting support portion 541 may include a rod (not shown) although not shown in the drawing. A portion of the tape wound from the taping roller portion 510 is positioned to face the end of the cutting support portion 541 when the head portion 20 is rotated one turn from the inside of the coil 1 and the cutting support portion 541 Can slide outside the opening 21 by means of the rod (not shown) that slides, and the tape can be stretched. And the cutter portion 543 slides in the outer direction of the opening portion 21 and cuts the tape. At this time, since the vacuum hole 542 is formed at the end of the cut portion 540, the tape can be cut by the cutter portion 543 in a state where one side is absorbed by the cut portion 540 and is in a tight state.

The automatic in-core packaging apparatus for sealing a coil wrapping paper according to an embodiment of the present invention may include an air spring unit 600. 9 is a view showing an arrangement of an air spring of an automatic in-care packaging apparatus for sealing a coil wrapping paper according to an embodiment of the present invention.

Referring to FIGS. 3 and 9, the air spring portion 600 may be disposed between the base 10 and the head portion 20. The air spring portion 600 can mitigate the impact caused by the movement of the head portion 20 inside the coil 1. For example, the imaginary central axis of the head portion 20 and the imaginary central axis of the inner side of the coil 1 may not coincide with each other. When the head portion 20 is inserted into the coil 1 and the pressing portion 200 radially spreads from the central axis of the head portion 20 and presses the inside of the wrapping paper or coil 1, The pressing body 230 positioned relatively close to the inner side can press and push the inner surface of the coil 1. At this time, the head portion 20 is pushed, so that the imaginary center axis of the head portion 20 and the virtual center axis of the coil 1 can be matched with each other. The pressing body 230 relatively far from the inner side of the coil 1 is extended radially outwardly of the head portion 20 and contacts the inner surface of the coil 1 when the virtual center of the head portion 20 The imaginary center axes of the shaft and the coil 1 coincide with each other and substantially the same radius from the imaginary center axis of the head portion 20 to the inner surface of the coil 1 and the portion where the pressing body 230 contacts with each other . In this process, the air spring unit 600 can relieve the impact generated by the pushing force of the pressing body 230.

Meanwhile, the air spring unit 600 may include a plurality of air springs 610 and 620. Referring to FIG. 9, the air spring unit 600 may include a first air spring 610 and a second air spring 620. The first air spring 610 and the second air spring 620 are preferably overlapped to intersect with each other. Although the first pneumatic spring 610 and the second pneumatic spring 620 are illustrated as being perpendicular to each other in the drawing, the present invention is not limited thereto. Therefore, even if the virtual central axis of the head portion 20 and the imaginary central axis of the coil 1 do not coincide with each other, if the pressing body near the inner side of the coil 1 pushes the inner side face of the coil 1, The virtual center axes can be matched with each other and efficient shock can be mitigated.

In addition, there is no one of the air spring portions 600, and a plurality of air spring portions 600 may be disposed to further disperse and alleviate the impact.

Although not shown in the drawing, the automatic in-order packaging apparatus for sealing a coil wrapping paper according to an embodiment of the present invention may include a sensor 30, a controller (not shown), and an actuator 40.

The sensor 30 may be disposed on one side of the head 20 to sense the position and arrangement of the coil 1. For example, the sensor 30 is disposed on the outer peripheral surface of the head portion 20, and the sensor 30 can measure the outermost diameter of the coil 1 or measure the inner surface diameter of the coil 1. At this time, it is preferable that the sensor 30 is a laser sensor, but it is also possible to use various sensors according to the intention of the manufacturer.

The controller may receive the electrical signal sensed by the sensor 30 and calculate the position of the coil 1 and the head 20. The controller may transmit an electrical signal to the actuator 40 to be described later so as to move the base 10 or the head unit 20 after the calculation is completed.

The actuator 40 can move the head unit 20 so that the imaginary center axis of the head unit 20 and the virtual center axis of the coil 1 coincide with each other by receiving the signal transmitted from the control unit. At this time, the actuator 30 can move the base 10 or the head 20 in the horizontal direction or the vertical direction. That is, the actuator 40 preferably moves the head portion 20 in the vertical direction from the imaginary center axis of the head portion 20. [

10 is a perspective view showing the use state of Fig. 1, and with reference to Fig. 10, the coil 1 is moved in the horizontal direction on the conveyor belt (not shown), and the actuator 40 can be moved in the vertical direction. That is, the virtual center axis of the coil 1 is vertically aligned with the virtual center axis of the base 10 or the head portion 20 through the horizontal movement of the conveyor belt, 10 or the imaginary central axis of the head portion 20 can be moved up and down so that the central axes of the head portions 20 can coincide with each other.

The sensor 30 senses the coil 1 stopped on the conveyor belt so that the imaginary center axis of the head unit 20 coincides with the virtual center axis of the coil 1, Can move the base 10 or the head portion 20 perpendicularly to the imaginary central axis (preferably in the horizontal direction or the vertical direction).

When the virtual center axis of the head unit 20 coincides with the virtual center axis of the coil 1, the control unit (not shown) controls the base 10 or the head unit 20 via the actuator 40, So that the head part 20 is inserted into the inside of the coil 1.

Hereinafter, the operation of the automatic in-core packaging apparatus for sealing a coil wrapping paper according to an embodiment of the present invention will be described.

First, the coil 1 placed on the conveyor belt is conveyed in the conveying direction of the conveyor belt. In order to align the imaginary central axis of the coil 1 with the virtual center axis of the base 10 or the head portion 20, the user moves the virtual center axis of the coil 1 horizontally through the conveyor belt Or the imaginary central axis of the base 10 or the head 20 is moved in the horizontal or vertical direction through the driving of the actuator 40.

When the virtual center axis of the coil 1 and the base 10 or the head portion 20 coincides with each other, the outer surface of the coil 1 wound in a donut shape is packed with a wrapping paper, and the wrapping paper is folded inward The user places the self-inserting packing apparatus for sealing the coil wrapping paper according to the embodiment of the present invention so as to be inserted inside the coil 1 wound in the donut shape.

The base 10 and the head 20 are moved and the head 20 is inserted into the coil 1. At this time, the brush portion 400 is positioned at the outer side of the inner side of the coil 1 The head portion 20 is inserted into the coil 1 to sweep away the wrapping paper located on the inner side of the coil 1 and make the wrapping paper more closely contact the inner surface of the coil 1. [ At this time, the brush part 400 is bent backward with respect to the inserting direction of the head part 20.

The center axis (not shown) of the head portion 20 rotates in one direction after the head portion 20 is inserted to the inside of the coil 1 by a predetermined depth according to the intention of the user. Since the central axis and the rail 100 are interlocked with each other, the rail 100 also rotates in one direction (clockwise in FIG. 7) by the rotation. At this time, the pressing portion 200, that is, the roller portion 210 located on the rail 100 is moved along the rail 100 while rotating, and the pressing portion 200 is pushed toward the outside of the head portion 20 And the pressing body 230 is brought into contact with the wrapping paper placed on the inner side of the coil 1. [ The pressing member 230 pushes the coil 1 while the pressing member 230 relatively close to the inner surface of the coil 1 contacts the wrapping paper placed on the inner side surface of the coil 1, A pressing member 230 which is moved in a direction perpendicular to the imaginary central axis and located relatively far from the inner surface of the coil 1 is brought into contact with the wrapping paper placed on the inner side surface of the coil 1, And the imaginary center axes of the coils 1 coincide with each other. In this case, the impact generated as the head 20 moves can be mitigated by the air spring unit 600 disposed between the base 10 and the head 20.

Next, the attaching portion 500 attaches the tape to the wrapping paper which is in close contact with the inner surface of the coil 1.

The first attachment portion 520 and the second attachment portion 530 slide outside the opening 21 through the opening 21 and come into contact with the wrapping paper which is in close contact with the inner surface of the coil 1. At this time, the tape wound from the tapping roller portion 510 is in a state in which the tip end of the tape is attracted by the vacuum hole of the cutting support portion 541. The first attachment portion 520 presses a part of the tape to be wound out to the outside of the opening portion 21 through sliding, and the tape is attached to the wrapping paper which is in close contact with the inner surface of the coil 1. The head portion 20 is rotated counterclockwise by a predetermined angle and the first attachment portion 520 attaches the tape attracted to the cutting support portion 541 to the wrapping paper closely attached to the inner surface of the coil 1 .

The second attachment portion 530 presses the tape again at the rear side in the rotational direction of the first attachment portion 520 in the process of rotating the head portion 20 in the clockwise direction, The wrapping paper that is in close contact with the side is more strongly attached to the tape.

When the rotation of one wheel of the head part 20 is completed, the first attachment part 520 is slid back to the inside of the opening part 21 and at the same time, the cutting support part 541 slides outwardly of the opening part 21 do. At this time, a portion of the tape facing the end of the cutting support portion 541 is attracted by the vacuum hole 542 located at the end of the cutting support portion 541, so that the tape can be maintained in the taut state, and then the cutter portion 543, The tape is slid to the outside of the opening 21 to cut the tape. The cut portion 540 including the cut support portion 541 and the cutter portion 543 is slid back inside the opening portion 21.

At this time, the second attachment portion 530 is in a state of protruding outside the opening 21 to press the wrapping paper in close contact with the inner surface of the coil 1, and the end portion of the tape cut by the cutter portion 543 The head portion 20 is rotated clockwise one more time and presses the tape attached to the wrapping paper one more time to finish the attachment of the tape.

In this state, since the end of the tape wound from the taping roller portion 510 is attracted to the cutting support portion 541, the process of packaging the inside of the other coil 1 is repeated, ) Can be immediately carried out on the wrapping paper which is in close contact with the inner side.

When the second attachment portion 530 slides inside the opening portion 21, the rail also rotates by the rotation of the central axis of the head portion 20, and the pressing portion 200 again moves toward the central axis of the head portion 20 Slide together. If a plurality of pressing units 200 are brought close to each other and neighboring pressing bodies 230 are brought into contact with each other, a control unit (not shown) controls rotation of the central axis of the head unit 20 or the rail 100 And sends an electrical signal to the actuator 40.

Finally, a control unit (not shown) sends an electric signal to the actuator 40 so as to pull out the head unit 20 located inside the coil 1 to the outside of the coil 1.

The present invention is not limited to the above-described embodiment, but may be applied to other embodiments of the present invention as set forth in the appended claims. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the scope of the present invention.
