The present invention relates to an insulation tape winding method and a device for winding an insulation tape used for a heating plumbing facility and the like so that a user can conveniently use it at a construction site.

In general, heating piping facilities and other indoor and outdoor plumbing equipment is wrapped with an insulating tape on the outer periphery of the piping pipe for the purpose of preventing heat loss and freezing.

The insulating tape is cut into a predetermined width enough to be held by the user from a relatively wide fabric and wound and supplied in a cylindrical shape.

1 shows a perspective view of this insulating tape 1.

As seen from this figure, the conventional insulating tape 1 is supplied to the end user in a form in which the cut tape is wound around a cylindrical bobbin 2.

The winding process of the conventional heat insulating tape 1 wound on the bobbin 2 is as follows.

First of all, the dandelion tape, formed into a fabric by a molding machine, is firstly wound on a large winding roller, and then wound by a separate winding device to a small bobbin to an appropriate thickness, transferred to a cutter, and then cut into a predetermined width. Supplied to the user.

Insulating tapes supplied in this state are shown in FIG.

However, in the state in which the heat insulating tape 1 is wound on the bobbin 2, there are limitations and inconveniences in use.

This is because the insulation tape (1) is wound on the bobbin (3) which is not deformed under any pressure, so the gap between the pipe and the pipe of the plumbing equipment for winding the insulation tape is narrow, or the pipe is installed close to the wall so that the bobbin (2 ) If the width of the insulation tape (1) wound around) is not able to pass through it, it is impossible to continue winding it on the pipe, so it is necessary to cut the insulation tape to the required length and use it. Because of the thick, there was a problem in use that is difficult to grip.

For this reason, the end user who received the insulation tape wound on the bobbin provided another simple winding machine at the construction site to relieve the inconvenience of use, and then unwound and rewinded the insulation tape wound on the bobbin. There is no bobbin in the present situation.

This insulation tape wound without bobbin can be bent when the user grips and firmly gripped by the hand, and can be easily escaped between narrow gap pipes and pipes, or between pipes and walls. The amount of winding up will be considerably greater than that of bobbins.

However, in order to rewind the insulation tape without bobbins, the user must prepare a simple winding machine, that is, a motor and a rotary ball separately, and in reality, in a construction site, a separate worker performs only such a rewinding work. It was not very useful to me.

In addition, in the manufacturing process, the winding and cutting process is carried out separately for each step, so it is inferior in terms of productivity.

In view of the above, an object of the present invention is to provide a method of winding an insulating tape, in which a thermal insulation tape is wound without a bobbin in one system so that the end user can conveniently use it directly.

It is another object of the present invention to provide a winding device for insulating tape which winds up the insulating tape without a bobbin in one system so that the end user can use it directly.

Winding method of the present invention for achieving the above object, the insulation tape fabric wound on the winding roller is unwound to be wound on the rotating shaft while being cut with a cutting mechanism in contact with the fabric wound in a state that is divided into equal parts on the rotating shaft This is achieved by removing the insulation tape wound on the axis of rotation from the axis of rotation in the final step.

The winding method includes the steps of drawing out the unwinded end of the insulating tape fabric wound around the winding roller to be wound on a rotating shaft which is rotated by the power of a motor; A step of winding the insulating tape fabric by rotating the rotating shaft by hand by applying a winding guide rod so that the insulating tape fabric is evenly wound on the rotating shaft; Positioning the cutting blade of the cutting mechanism in contact with the fabric so that the insulation tape is cut in the unwinding direction; Driving the motor in a state in which the cutting blade is in contact with the heat insulating tape fabric, and winding the heat insulating tape cut in the rotating shaft rotated by the driving force of the motor; A step of cutting in the transverse direction such that the driving of the motor is stopped when the insulating tape of constant thickness is wound on the rotating shaft, and the insulating tape wound on the rotating shaft is separated from the original fabric side; Lifting the rotating shaft to take out the winding guide rod and the insulating tape sequentially from the rotating shaft; And a step of detaching the cutting blade from the insulating tape fabric so that the cutting blade does not cut the fabric in order to rewind the insulating tape fabric to the rotary shaft.

The winding apparatus of the present invention includes a frame; A winding roller detachably attached to the frame and rotatably installed to wind the insulation tape fabric; A guide roller for guiding the insulating tape fabric released from the winding roller; A cutting mechanism rotatably installed to allow the cutting blade to come into contact with and be detached from the insulating tape fabric in order to cut the transferred insulating tape fabric; A rotating shaft which is rotated by receiving power of a motor so as to wind up the insulation tape fabric cut by the cutting mechanism, and is detachably attached to the frame; Braking means for stopping the winding roller when an appropriate amount of the insulated cut tape is wound around the rotating shaft; Motor control means for controlling the rotation of the motor.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The upper portion of the rear frame 11 is formed with a boss opening 13 is formed in the upper portion so that the take-up roller 20 is detachably seated.

At the rear of the front frame 12, bearings 14, 15 and 16, to which the guide roller 30 and the cutting mechanism 40 are fixed, are fixed. In the front, the rotation shaft 50 is seated and disengaged. The boss 17 which opens to the upper side so that possible is formed.

The winding roller 20 is wound around the heat insulating tape fabric 21 and both ends thereof are seated on the boss 13 of the frame 10.

The guide roller 30 guides the insulation tape fabric 21 released from the winding roller 20, and includes a first guide roller 31, a second guide roller 32, and a third guide roller 33. It is.

The first guide roller 31 is fixed to the bearing 14 to support the lower portion of the heat insulating tape fabric 21 released from the winding roller 20, and is not shown, but is insulated by installing a known meter You can also check the total length of the tape.

The second guide roller 32 keeps the tension of the heat insulating tape fabric 21 by allowing the upper surface of the heat insulating tape fabric 21 passing through the first guide roller 31 to come into contact with each other.

The third guide roller 33 supports the lower portion of the insulating tape fabric 21 passing through the second guide roller 32 so that the third guide roller 33 can be cut by the cutting mechanism 40 while maintaining the tension.

The cutting mechanism 40 is rotatably installed on the front frame 12 on the front frame 12 at the upper portion of the third guide roller 33, and a plurality of cutting blades 42 are formed at regular intervals forward. The fixed shaft 41 extends at one end thereof, and a rotary knob 43 is formed.

The insulating tape fabric 21 passing through the third guide roller 33 is drawn out toward the rotation shaft 50, and the lower end of the cutting blade 42 of the cutting mechanism 40 is rotated with the third guide roller 33. By 50, it is possible to be placed on the upper portion of the insulating tape fabric 21 is tense.

Rotating shaft 50 is free to be seated on the boss 17 and detached, one end is engaged with the drive gear 61 of the motor 60 is formed with a driven gear 51 to receive power.

The motor control means 70 is composed of a control box 71 that can switch operation so that an operator can rotate and stop the motor 60.

The braking means 80 is for preventing the rotation of the take-up roller 20 by the inertia of the rotational force after the operator makes a switch operation to stop the motor 60, and the brake band 82 operated by the closing moon 81. ) Is composed of a known band brake mechanism which is wound around the winding roller 21.

The winding guide rod 90 becomes a rod-shaped body that is considerably thinner than the diameter of the rotating shaft 50, and a bent portion 91 is formed at one end so as to be easily separated in the state where the insulating tape is cut and wound on the rotating shaft 50. have.

The position shown in FIG. 3 shows the state seen from the back of the winding-up apparatus, and the worker's working position becomes the position which looks at the side in which the rotating shaft 50 was placed in the side of the control box 71. FIG.

Looking at the process of winding the insulation tape cut in the winder configured as described above without the bobbin is as follows.

First, the winding roller 20 on which the insulation tape fabric 21 produced by the molding machine is wound is seated on the boss 13 of the rear frame 11, and the rotary shaft 5 is attached to the boss 17 of the front frame 12. The seating gear 51 is engaged with the drive gear 61 of the motor 60 by being seated.

At this time, the motor 60 is in a stopped state.

Then, the rotary knob 43 is rotated to rotate the fixed shaft 41 on which the cutting blade 42 is fixed so that the cutting blade 42 is lifted upward, as shown by the virtual line A of FIG. Roll up the heat insulating tape fabric 21 from the lower part of the rotating shaft 50 to the upper part through the 1st 2nd 3rd guide roller 31, 32, 33, and rotate it by hand using the winding guide rod 90. By rotating the 50 and rotating the rotary knob 43 again downward, the tip of the cutting blade 42 is placed on the upper portion of the insulation tape fabric 21 to drive the motor 60.

When the motor 60 is driven, the rotating shaft 50, which is powered by the driving gear 61 and the driven gear 51, rotates to release the heat-insulating tape fabric 21 wound around the winding roller 20.

While rotating the heat insulating tape fabric 21 while rotating the first second third guide rollers 31, 32, 33, a tension is formed in a taut state, and the shaft is cut in the longitudinal direction released by the cutting blade 42. Wound at 50.

This process is illustrated in more detail in FIG.

Referring to this figure, (a) of FIG. 6 shows a state in which the insulation tape fabric 21 is wound around the rotating shaft 50 in the course of continuous operation, which is cut by rotating the rotary knob 43. The blade 42 is lifted so that the insulation tape fabric 21 is not cut even when pulled by hand to wind the rotating shaft 50.

At this time, the end portion of the insulating tape fabric 21 wound on the rotating shaft 50 is in a state of being cut by the cutting blade 42, but as shown in (b) of FIG. When rotating 50) manually, the unincision area is wound.

In such a state, when the rotary knob 43 is rotated downward so that the cutting blade 43 is in contact with the insulating tape fabric 21 and the motor 60 is driven, the insulating tape fabric as shown in FIG. As the 21 is cut, it is wound around the rotation shaft 50.

When the insulation tape cut on the rotating shaft 50 is wound to an appropriate thickness, the motor 60 is stopped, and the brake band 82 stops the inertia rotation of the winding roller 20 by stepping on the pedal 81.

When the motor 60 is completely stopped, the operator cuts an arbitrary position between the cutting blade 42 and the rotating shaft 50 in the horizontal direction by using a separately prepared blade or the like to the insulation tape fabric 21 and the rotating shaft 50. The wound insulating tape is separated, and the rotating shaft 50 is separated from the boss 17 to take out the winding guide rod 90.

The winding guide rod 90 may be separated by pulling the bent portion 91 or hanging on another hooked portion by pulling the rotating shaft 50.

The insulating tape wound around the rotating shaft 50 from which the winding guide rod 90 has been removed is pushed out in the axial direction of the rotating shaft 50, and the rotating shaft 50 is seated on the boss 17 again to continue the work.

At this time, the plurality of heat insulating tapes wound on the rotating shaft 50 are not disturbed because they are connected to each other by a portion not cut when the first winding on the rotating shaft 50.

The completed insulating tape may be finally cut and supplied to the parts connected to each other, or may be supplied as it is so that the user may cut off the parts to which they are connected.

According to the present invention as described above, the insulation tape is cut and cut in a winding system consisting of a single system to wind up without bobbins, thereby improving productivity and allowing the user to conveniently use the insulation tape.
