Hereinafter, the technical spirit of the present invention will be described in more detail with reference to the accompanying drawings.

However, the accompanying drawings are only examples to illustrate the technical idea of the present invention in more detail, and thus the technical idea of the present invention is not limited to the accompanying drawings.

The present invention relates to a film rewind device for transferring a film wound on a roll of fabric to a take-up roll.

Therefore, the rewind apparatus of this invention also has the direct drive roller 10 which is made to contact the film 1a supplied from the original roll 1, and is rotatable by a power.

In addition, the motor 20 is connected to the direct drive roller 10 to rotate the direct drive roller 10.

In addition, the fabric roll 1 has a clamping part 31 fixed or detached so as to be rotatable relative to the center thereof, and the fabric roll fixing having a control unit for selectively controlling the fixing or detachment of the fabric roll 1. Means 30.

In addition, the take-up roll fixing means 40 has a clamping portion 41 which is fixed or detached so as to be rotatable relative to the center of the take-up roll 2 and has a control unit for selectively controlling the fixing or detachment of the take-up roll. Has

The direct drive roller 10, the motor 20, the original roll fixing means 30, the winding roll fixing means 40 as described above are already known and can be implemented in various forms, so a detailed description of the general structure is omitted. do.

By the way, the present invention has an object to be able to move the film from the plurality of raw rolls to the plurality of take-up rolls simultaneously using one device.

The inventor of the present application was able to grasp some matters required for simultaneously transferring a film from a plurality of fabric rolls to a plurality of winding rolls after a long research and effort.

First, a plurality of rolls of raw material are rotated and stopped at the same time, a plurality of take-up rolls are rotated and stopped at the same time, the take-up roll and the raw rolls should be rotated at the same time and stopped at the same time as the moving amount of the film, and the film being moved It was to be maintained.

Second, even if the first condition is satisfied, the film is wound on the corresponding winding roll according to the state in which the film is wound on each fabric roll, so that the film is wound tightly on all the winding rolls even under such conditions. Means were required.

For this reason, in the present invention, a plurality of raw roll fixing means 30 is provided, and the raw roll is closely adhered to the raw roll 1 when the raw roll is rotated in a state fixed to the clamping part 31 of the raw roll fixing means 30. It is provided with a far-end contact roller 50 to be in a state.

In addition, a plurality of take-up roll fixing means 40 is provided, and the take-up roll 2 is directly driven when the take-up roll 2 is rotated in a state of being fixed to the clamping portion 41 of the take-up roll fixing means 40. It is to be in close contact with the roller (10).

That is, the original roll is rotated while maintaining the state in close contact with the original contact roller 50, and the winding roll is rotated while maintaining the state in close contact with the direct drive roller (10).

However, when the fabric roll is in close contact with the fabric contact roller 50, it may be selectively released or adhered again, so that when the problem occurs in the process of work, it is possible to cope with the installation and replacement of the fabric roll (1). It is possible.

Of course, the take-up roll is also in close contact with the direct drive roller (10) can be selectively released, or should be in close contact can not only cope when problems occur in the work process, but also install and replace the take-up roll (2) Is possible.

Therefore, the roll roll fixing means 30, which is a component of the present invention, is implemented to allow left and right rotation while keeping the roll roll 1 fixed to the clamping portion 31 as shown in FIGS.

In addition, the far-end contact roller 50 is located on the line that is rotated left and right in the state in which the far end roll is fixed to the clamping portion 31 of the far end roll fixing means 30 to be in close contact with the far end roll.

In addition, the fabric rolls are installed to correspond to each fabric roll fixing means 30, and the fabric rolls are respectively fixed to the fabric contact rollers 50 while the fabric rolls are fixed to the clamping portions 31 of the fabric roll fixing means 30. It is provided with a plurality of stationary roll rotation means 60 for selectively rotating a portion of each of the original roll fixing means 30 to the left or right to close or close contact.

In addition, the winding roll fixing means 40, which is a component of the present invention, is rotated left and right while the winding roll is fixed to the clamping part 31, and the winding roll is fixed to the direct drive roller 10 or Implement to break out.

In addition, a portion of the winding roll fixing means 40 is disposed so that the winding rolls come into close contact with the direct drive roller 10 or the adhesion is released while the winding rolls are fixed to the clamping portions 31 of the winding roll fixing means 40, respectively. It is provided with a fixed winding roll rotating means 70 for selectively rotating left and right.

The structure to enable the left and right rotation of the original roll fixing means 30 or the structure to enable the left and right rotation of the take-up roll fixing means 40 is the raw roll fixing means 30 or the winding roll fixing means 40. A portion of) may be achieved through a hinged structure to the base 80 of the rewind device as shown in the figure.

The fixed fabric roll rotating means 60 or the fixed winding roll rotating means 70 may be implemented in various forms.

To explain a specific example, the fabric roll fixing means 30 or the winding roll fixing means 40 are rotated manually, and the fabric roll fixed to the fabric roll fixing means 30 by the tension of the spring is in contact with the fabric. The winding roll fixed to the roller 50 or fixed to the winding roll fixing means 40 may be implemented to be in close contact with the direct drive roller 10. (not shown)

In addition, as shown in FIGS. 1 and 2, the roll roll fixing means 30 or the winding roll fixing means 40 may be left and right rotated by the front and the back of the cylinders 61 and 71.

By the way, only the above configuration has a limitation in that the film is wound tightly on all winding rolls.

That is, since the rolled film is slightly different from the rolled state, the same rolled state cannot be secured through a constant adhesion.

Therefore, the original roll is further provided with a far-end side pressure control means (not shown) that can adjust the contact pressure to be in close contact with the appropriate pressure in the original roll is in close contact with the original contact roller 50 by the roll rotation means (60).

It is further provided with a winding side pressure adjusting means (not shown) which can adjust the adhesion pressure so that the winding roll is in close contact with the direct drive roller 10 by the fixed winding roll rotating means 70 to be in close contact with the appropriate pressure. desirable.

When the winding side pressure adjusting means is provided, the film can be wound around the winding rolls having different diameters using one device.

In other words, in some cases, the winding of the larger diameter roll of the winding is performed, and in some cases, the winding of the smaller diameter of the winding of the winding is performed.

Of course, in order to be able to use the winding rolls having different diameters in one rewinding operation, the fixed winding roll rotating means 70 and a plurality of winding side pressure adjusting means corresponding thereto are provided. Winding roll corresponding to) should be in close contact with the direct drive roller 10 with a separate contact pressure.

The far-end side pressure adjusting means or the winding-side pressure adjusting means as described above can be implemented in various forms.

In the structure to be in close contact with the tension of the above-described spring can be implemented in the form of narrowing or increasing the compression length of the spring.

For example, tightening the bolt moves the back of the spring further toward the tighter position, which narrows the compression length of the spring, resulting in greater adhesion, while loosening the bolt moves the back of the spring in the opposite direction This is to increase the compression length of the spring to obtain a weaker adhesion.

In the structure of the fixed fabric roll rotating means 60 or the fixed winding roll rotating means 70 having a cylinder, the adhesion force can be adjusted by adjusting the distance that the cylinder shaft of the cylinder moves forward and backward.

However, such a structure has a disadvantage in that the adhesion cannot be finely controlled.

As another form, the forward and backward distances of the cylinder shaft may be set in the same manner and may be implemented in such a manner that the positions fixed to the lower base 80 of the cylinder can be moved at minute intervals.

Such structures are simply set to an appropriate level of adhesion.

Therefore, through the structure as described above should be adjusted from time to time the adhesive force of the original roll 1 and the original contact roller 50 and the adhesion of the take-up roll (2) and the direct drive roller (10).

This is because the structure that obtains the adhesive force through the method as described above is gradually weakened as the film of the raw roll is moved in the winding roll direction.

Therefore, even if the film of the roll is moved in the winding roll direction, the same adhesion between each roll and the fabric contact roller 50 is secured, maintaining the adhesion to ensure the same adhesion between the winding roll and the direct drive roller (10) It is preferable to provide further means.

Such adhesion maintaining means can be implemented in various forms.

As a specific example, as shown in FIGS. 1 and 2, the fixed roll roll rotating means 60 or the fixed winding roll rotating means 70 moves forward or backward through the cylinders 61 and 71. When the winding roll fixing means 40 to rotate left and right, it is provided with a valve so that only a constant pressure is applied to the cylinder (61, 71).

That is, by operating the valve to adjust the air pressure or the hydraulic pressure applied to the cylinder (61, 71), the original roll 1 is in close contact with the original contact roller 50 (winding roll directly to the direct drive roller 10) at an appropriate pressure. This contact pressure is to maintain a constant by applying a constant air pressure or hydraulic pressure to the cylinder (61, 71).

In such a structure, it is preferable to use a pneumatic cylinder unless the film is very hard because the hydraulic cylinder using the hydraulic pressure is very strong.

For the case of rewinding the film from the original roll of the same level to the take-up roll at the same time to facilitate the setting of the contact pressure by installing a gauge in the manner of adjusting the air pressure or hydraulic pressure applied to the cylinders 61 and 71 as described above. A range of appropriate pressure data can be secured.

The clamping part 31 and the control unit 31 and the control unit of the roll roll fixing means 30, which is a component of the present invention, may be implemented in various forms.

However, the conventional clamping parts 31 and 41 and the control part have been quite troublesome to use, and have a complicated structure.

Therefore, the applicant of the present invention presents the clamping parts 31 and 41 and the controller which are easy to use and have a simple structure as shown in FIGS. 4 and 5.

4 and 5 show the clamping portion 31 of the roll roll fixing means 30, the clamp presses both sides of the central portion of the roll roll (1) to hold the roll roll (1) and the roll roll (1) A fixed pressurizing body 32 and a moving pressurizing body 33 adapted to rotate together with each other;

The moving press body 33 is moved in the direction of the fixed press body 32 or in the opposite direction to fix or fix the original roll 1 between the fixed press body 32 and the moving press body 33. It is embodied in the form having a cylinder 34 to be separated from the roll roll.

4 and 5 in the structure having a clamp as the control unit of the roll roll fixing means 30 is implemented in a form that can selectively apply air pressure or hydraulic pressure to the cylinder (34).

As a specific example, the operator has a switch that can be stepped on the foot, but when the operator presses the switch, the cylinder shaft of the cylinder 34 is reversed can be released from the roll roll, when the foot is released from the switch the cylinder shaft is moved forward again The gap between the fixed pressurizer 32 and the mobile pressurizer 33 is narrowed to fix the roll roll 1.

In the above structure, the switch determines whether the cylinder 34 is applied to the front of the cylinder 34 or to the rear in applying air pressure or hydraulic pressure.

Hereinafter, the operation of the present invention will be described using the accompanying drawings.

2, each fabric roll fixing means 30 in the state in which the clamping portion 31 of each fabric roll fixing means 30 is rotated in the opposite direction of the fabric contact roller 50, respectively. To the clamping portion 31.

In addition, the clamping portion 31 of each of the take-up roll fixing means 40 in the state that the clamping portion 31 of the take-up roll fixing means 40 is rotated in the opposite direction of the direct drive roller 10 ( 31).

In this state, the fixed fabric roll rotating means 60 is operated so that the fixed fabric roll is in close contact with the fabric contact roller 50 as shown in FIG. 1, and the film 1a is pulled from the fabric roll 1 by pulling the film 1a. ) Is wound on the take-up roll (2) via the direct drive roller (10).

Then, the fixed winding roll rotating means 70 is operated so that the winding roll 2 is brought into close contact with the direct drive roller 10 and supplied from the original roll 1 and the film 1a wound on the winding roll 2 is in a taut state. To be

In this manner, the tensioning roll 2 may be slightly rotated manually.

When the film 1a is brought into a taut state, the film 1a is brought into close contact with the direct drive roller 10 as well.

When power is applied to the motor 20 in such a state, the direct drive roller 10 is rotated by the motor 20, and the winding roll 2 which is in close contact due to the rotational force is rotated.

In addition, as the winding roll 2 is rotated and the film is wound around the winding roll, the original roll 1 is rotated, and the original roll contact roller which is in close contact with the original roll 1 as the original roll 1 is rotated ( 50) will also rotate.

The winding roll 2 is rotated while being in close contact with the direct drive roller 10 to wind the film, and the original roll 1 is supplied with the film while being in close contact with the original contact roller 50. The rewinding is performed while the film is always kept taut.

 Further, the take-up roll 2 and the far-end roll 1 are rotated at almost the same time and stopped at the same time.

If the state of the fixed fabric roll 1 in the above state is the same, that is, if the film is wound on the same condition and has the same outer diameter on the fabric roll, there is no problem, but practically such a case does not exist.

Therefore, the film of a certain roll is often too tightly wound on the take-up roll, while the film of the other roll is often less than expected.

In addition, the specific fabric roll is too tightly adhered to the fabric contact roller 50, the film is damaged, while the other fabric roll is often too weakly adhered to the fabric contact roller 50.

Therefore, each of the fabric rolls should be appropriately adjusted to the adhesion that is in close contact with the fabric contact roller (50).

Therefore, by rotating the motor 20 to check the state of the film wound on the take-up roll, and adjusts each fabric is in close contact with the fabric contact roller 50 at an appropriate pressure through the fabric-side pressure control means.

Through this, even if the state in which the film is wound on each fabric roll is different or there is some difference in the diameter of the fabric roll, each fabric roll adheres to the fabric contact roller 50 at an appropriate pressure so that the film is wound tightly on the winding roll. It can be done.

When the setting operation is completed, the motor 20 is continuously driven so that the film of the original roll 1 is transferred to the take-up roll 2 as desired.

On the other hand, it is provided with a plurality of fixed winding roll rotating means 70 of the present invention and selectively operated only a part of the plurality of fixed winding roll rotating means 70 to selectively select only a part of the plurality of winding roll fixing means 40 If the right rotation can be implemented, a plurality of fabric rolls and a take-up roll may be fixed to the fabric rolls and the take-up rolls, even if the device can rewind at the same time.

That is, even if the device can be rewinding from four fabric rolls to four winding rolls at the same time by fixing four fabric rolls and four winding rolls, if the fixed winding roll rotating means 70 is four, four can be worked simultaneously. Of course, you can only work on one, only two, or only three.

According to this structure, even if a failure occurs in some of the winding roll fixing means 40, a situation in which the rewind device itself must be stopped for repair does not occur.

That is, the plurality of winding roll fixing means 40 and the plurality of winding roll fixing means 40 are rotated left and right by one fixed winding roll rotating means 70, so that all the winding rolls are directly driven rollers ( 10) Even if the structure is in contact with the work roll is only a part of the roll roll fixing means 40, the selective work is possible.

However, in such a structure, when a failure occurs in the winding roll fixing means 40, the rewinding device itself should be stopped.

In the present invention, when a large amount of film is wound on the roll, and a relatively small amount of film is wound on the winding roll, when the direct drive roller 10 is stopped, the light winding roll may be stopped immediately, but a heavy roll of roll The phenomenon of stopping later than the take-up roll occurs due to its weight and rotational force.

Therefore, it is preferable to have a clutch (not shown) for forcibly stopping the rotation of the direct drive roller 10 and the far-end contact roller 50, respectively.

In this case, each clutch should be operated simultaneously so that the direct drive roller 10 and the far end contact roller 50 are stopped at the same time.

In the present invention, the above-described configuration alone brings considerable difficulty in rewinding a thin stretch film such as a wrapping wrap.

That is, since the thin stretch film is easily stretched, problems such as wrinkles occur when the film is wound on the take-up roll.

Even large rolls of fabrics with thin stretch films often have a significant amount of wrinkles, so there is a need to have the film roll around the winding rolls as these wrinkles are stretched.

The inventor of the present application devised a structure as shown in Figure 1 as a method for solving this.

1 is further provided with a friction adjusting roller 90 between the fabric contact roller 50 and the direct drive roller 10, the film (1a) of the fabric roll (1) is friction control with the fabric contact roller 50 The roller 90 and the direct drive roller 10 are wound around the roll roller 2 in order.

The friction control roller 90 has a hollow portion inside and is fitted to a fixed shaft 81 having the hollow portion fixed therein so as to rotate about the fixed shaft 81 so that wrinkles occur in the film wound on the roll 1 of the fabric. If it is, it is to be rotated by the adhesion of the film and the friction control roller 90 and the moving force of the film.

Of course, if the film is not wrinkled because the film gently passes through the friction control roller 90, the friction control roller 90 is not rotated.

For this reason, wrinkles of the thin stretch film held on the roll of the fabric are unfolded, and as a result, wrinkles do not occur in the film wound on the take-up roll.

In the related art, the work of fixing the roll of fabric to the roll roll fixing means 30 was very inconvenient.

That is, the relatively light one was lifted by the attraction force and fixed to the clamping part 31 of the roll fixing means 30, and the heavy one was moved in the state lifted by a hoist or the like and then fixed to the clamping part 31.

The present invention installs a conveyor 100 in which the original roll is moved in a range in which the clamping portion 31 of the original roll fixing means 30 is rotated left and right in order to solve this problem.

However, the present invention is to enable the rewinding for the various size of the roll of the fabric, so that the conveyor 100 is moved up and down to precisely move the heavy roll of the fabric to the clamping portion 31 of the roll fixing means 30 Make adjustments possible.

That is, as shown in Figure 6 in the state that the clamping portion 31 of the original roll fixing means 30 is moved in the opposite direction of the original contact roller 50, the original roll to the clamping portion 31 of the original roll fixing means 30 But the center of the roll of the fabric roll should be located in a position where it can be clamped accurately. The diameter of the roll of fabric used is different, so the height of the conveyor is required to be adjusted in order to place the center of the roll of fabric.

In the field where the rewinding work is mainly performed, there are many fabric rolls to be subjected to rewinding, so it is usually stored by stacking them on the barette when storing the fabric rolls.

Considering the situation of the work site there is a need to facilitate the positioning of the roll of fabric on the barette on the conveyor (100).

To this end, as shown in Figure 7, the fabric rolls can be mounted on the barrets (3) are stacked while forming a stage, and the upper and lower height adjustment is possible to be mounted on the top of the fabric rolls of the mounted barrett (3) Barrett mounting device 110 can be provided to facilitate the movement of the roll to the conveyor (100).

The reason for allowing the height adjustment of the up and down of the barrett mounting machine 110 is limited to moving the conveyor 100 up and down, and the original roll (1) is laminated on the barrett 3 while forming a stage. Therefore, the top and bottom height control of the conveyor 100 and the top, bottom height adjustment of the Barrett mounting device 110 is to facilitate the mounting on the conveyor 100 to facilitate.

As in the present invention, the direct drive roller 10 and the fabric contact roller 50 are inevitably lengthened in the structure to fix the plurality of fabric rolls and the winding rolls in one device.

However, when the direct drive roller 10 and the fabric contact roller 50 are lengthened, deflection may occur. Such deflection may reduce the rewinding workability of the film.

Therefore, it is preferable that the direct drive roller 10 and the far-end contact roller 50 have bearings installed at regular intervals so that deflection does not occur even if their lengths are long.

The direct drive roller 10 and the far-end contact roller 50 may be implemented to have a good weaving degree by connecting a shorter length to a coupling to ensure a longer length.

Reference numeral 35 is a bush, 101 is a cylinder for adjusting the upper and lower height of the conveyor, 111 is a cylinder for adjusting the upper and lower height of the Barrett mounting machine.
