Description

A resin film roll end processing device and a tail processing method, a resin film roll having a roll formed by the processing method thereof, and a resin film roll product thereof

The present invention relates to a reel processing apparatus for a resin film roll which is processed by a method in which a winding of a film roll of a resin film sheet is wound at the end, that is, a roll tail, which is easily unwound. And a roll processing method, a resin film roll having a roll formed by the processing method, and a resin film roll product.

For example, a plastic film sheet for food packaging is provided as a film roll of a take-up shape. The film for food packaging is extremely thin to 5 to 20 μm, and can be visually confirmed to be colorless and transparent in the state of covering the food, and has an adhesive property for sealing the food inside, so as to be in close contact with the food. Tray or saucer. Therefore, there is a case where even if the film roll is to be unwound and is to be peeled off from the roll, it cannot be easily peeled off.

In order to allow the tail to be easily peeled off, for example, a sheet to which a pick-up paper or tape is attached is circulated. However, since the pick-up sheet is small and attached to the center portion in the axial direction, when the user wants to take the pick-up sheet and peel off the tail, there is a following problem: if the center portion is applied intensively Force, while the other parts remain in a state of adhesion, only the central part is torn, and as a result, it cannot be peeled off and cannot be unwound. Further, there is a problem that at the time of manufacture, it is necessary to attach a pick-up sheet or to require a device, so that the manufacturing cost increases.

Therefore, a method other than attaching a pick-up piece has been proposed. For example, Patent Document 1 proposes a cutting end bending device that bends a tail portion of a film roll. The cutting end bending device is configured such that a film roll is formed and the jetting air is ejected at the end portion when the portion which is the end of the winding is cut, and the folded portion is formed in the portion which becomes the tail by the air current.

Further, Patent Document 2 discloses a device for forming a gripping portion of a plastic material wound film in which a portion of the winding portion is formed several times at the end of the winding to form a grip portion. The apparatus is configured to: when the film roll is wound on the take-up shaft (paper tube), the rotation of the take-up shaft is stopped, and the take-up shaft is rotated in the reverse direction to take up the tail portion Forming an enlarged grip portion.

As shown in FIG. 5, a film roll R-based film sheet manufactured by the apparatus of Patent Document 2 is wound around a paper tube 4, and is provided with a grip winding unit 20 for grasping the winding unit 20 An enlarged grip portion formed by winding the portion of the tail in a direction opposite to the winding direction of the film sheet.

However, in the cutting end bending device described in Patent Document 1, since the portion of the winding tail is folded back, the portion which is folded back by the adhesiveness of the film sheet is in close contact with the outer peripheral surface of the film roll, and A portion of the film roll in which the folded portion is continuous is in close contact with the film roll on the inner side thereof, and as a result, it is difficult to peel off the end portion.

Further, in the device described in Patent Document 2, since the enlarged winding portion is formed in the axial direction, the gripping operation becomes easy, and the entire region in the direction along the axial direction can be peeled off, so that it does not exist. Tearing and other situations. However, in order to increase the take-up portion and rotate the take-up shaft in the reverse direction, it is necessary to use a reversible motor for the drive motor of the take-up shaft, or to provide a transmission path according to a clutch mechanism or the like. The mechanism for changing the direction of rotation and transmitting the rotation of the motor to the take-up shaft is complicated. Further, when the enlarged winding portion is formed, it is necessary to rotate at a speed much smaller than the rotation speed at which the film roll is formed, so that the rotation control of the driving motor becomes complicated. Further, when the paper tube is used on the take-up shaft, there is a possibility that the end portion of the paper tube is damaged or broken by the change of the rotation direction.

Accordingly, an object of the present invention is to provide a reel processing apparatus and a tail processing method for a resin film roll which can change the rotation direction and the rotation speed of the take-up shaft with a simple structure and thereby form a grip portion at the end of the winding. A resin film roll having a roll formed by the treatment method thereof, and a resin film roll product.

As a technical means for achieving the above object, the reel processing apparatus for a resin film roll of the invention of claim 1 is formed by winding a roll of a film roll of a resin film sheet to form the roll. The tail gripping portion is characterized in that: a film roll transfer means is provided which, when the take-up shaft is rotated in the forward direction at the winding position to form a film roll, winds up the film to the roll immediately before completion The tail processing position is moved; the film roll rotating roller is in contact with the film roll transferred to the winding end processing position, so that the rotation of the film roll due to inertia is stopped, and the film roll can be rotated in the reverse direction; a tail processing means for contacting the film roll at the processing position of the winding end, and unwinding the film sheet by the rotation of the film roll in the opposite direction to form a winding portion for gripping; When the tail processing position is moved, the end portion of the film roll is cut to form a winding tail, and the inertia rotation of the film roll is stopped by the contact of the film roll rotating roller, and the film roll rotating roller is rotated to form a film roll. The winding shaft is rotated in the opposite direction to connect the winding end processing means to the end of the winding to rotate the film roll in the reverse direction, thereby forming a grip winding portion at the end of the winding.

For example, as a device for manufacturing such a resin film roll, for example, there is a turret type automatic reeling machine which is used as a take-up shaft by a turret mechanism The paper tube is moved from the winding position of the film sheet to the respective positions of the cutting position of the film sheet and the discharge position of the film roll which is taken up by the film sheet, and the corresponding processing is performed at each position.

Further, the film sheet fed at the winding position is taken up to the paper tube, and is moved to the tail processing position by the turret mechanism or the like immediately before completion. At this time, the film sheet is not cut, and the front end of the film roll is connected to the roll of the subsequent film roll. Therefore, the winding end is separated from the winding head by the cutting of the cutter disposed at the position in the middle of the winding end processing position. Thereby, the front film roll is completed. Thereafter, it is transferred to the end of the processing position. Further, when the film is cut at the end of the roll, the film sheet is in an appropriately stretched state, and after the cutting, the film is slightly rotated in the forward direction by the inertia as in the case of forming the film roll.

When the film roll is transferred to the tail processing position, the film roll rotating roller is brought into contact with the film roll. Thereby, the film roll that is rotated by inertia is stopped. Further, the winding end processing means is operated to be connected to the winding end of the film roll. In this state, the film roll rotating roller is operated to rotate the film roll in the reverse direction. The number of rotations is much smaller than the number of rotations when the film sheet is taken up to the paper tube, and by the reverse rotation, the winding tail is peeled off by the above-described winding processing means and wound up to form a gripping take-up portion.

For the packaging or the like, the film roll on which the gripping take-up portion is formed is discharged from the tail processing position or after being transferred to the discharge position, and is discharged to the next step.

Further, in the reel processing apparatus for a resin film roll of the invention of claim 2, the film roll rotating roller is supported by a free end portion of a swing arm that is swingably supported at a base end portion, and the swing arm is provided by the swing arm The oscillating motion advances and retreats with respect to the film roll, and comes into contact with the film roll during advancement.

The film roll rotating roller may be disposed at the initial position, and the film roll transferred to the winding end processing position may be in inertial rotation stop by contact with the film roll rotating roll, but the film roll which is completed by the impact at the time of contact may be subjected to The flaw of injury. Therefore, the film roll rotating roller can be swung between the position in contact with the film roll at the end of the film processing position and the retracted position, and can be swung and contacted with respect to the film roll transferred to the end of the film processing position.

Further, in the reel processing apparatus for a resin film roll of the invention of claim 3, the winding end processing means includes a winding tail connecting plate which is advanced and retracted with respect to the film roll at the end processing position, and is connected to the film during advancement. At the end of the roll, the rotation of the film roll in the opposite direction restrains the tail.

The tail processing device is constructed by a tail connecting plate composed of a sheet material. When the grip portion winding portion is formed at the end of the film roll, the film sheet is unwound from the tail of the film, but in a state where the tail web is in contact with the tail, the film roll is rotated in the forward direction. The tail is peeled off.

Further, in the reel processing apparatus for a resin film roll of the invention of claim 4, the surface of the winding tab is made of a rubber double structure, and the hardness of the surface rubber is made larger than the hardness of the inner rubber.

In order to exert an appropriate frictional force in a state in which the roll connecting plate is brought into contact with the film roll, a structure in which rubber is attached to the surface of the roll connecting plate is used. Further, the rubber is as follows: a double structure is formed, and the rubber on the inner side is made softer than the rubber on the surface side.

Further, the method for processing the resin film roll of the invention of claim 5 is for winding the film roll of the resin film sheet to form a gripping portion for gripping the tail of the film. When the winding shaft is rotated in the winding direction to form a film roll at the winding position, the film roll is moved to the tail processing position immediately before completion, so that the film is moved to the winding end processing position. After the rotation of the roll is stopped due to the inertia, the film roll is rotated in the opposite direction, so that the winding end processing means is in contact with the film roll located at the winding end processing position, and the film roll is rotated in the opposite direction from the winding end. A gripping portion for gripping is formed.

A method of forming a gripping take-up portion at the end of a film roll. The film roll wound by taking up the film sheet to the take-up reel is cut at the end of the roll and transferred to the above-mentioned tail processing position. At the end of the winding position, the winding direction is unwrapped in the opposite direction to the direction of rotation when the film roll is formed, and the gripping take-up portion is formed by the unwound film sheet.

Further, the method for processing the resin film roll of the invention of claim 6 is characterized in that the roll processing device of the resin film roll of any one of claims 1 to 4 is used at the end of the film roll. A gripping portion for gripping is formed.

Further, the resin film roll of the invention of claim 7 is characterized in that it has a gripping take-up portion formed by the winding method of the resin film roll of claim 5 or claim 6.

Further, the resin film roll product of the invention of claim 8 is characterized in that the resin film roll of claim 7 is housed in a storage box.

According to the tail processing device or the tail processing method of the resin film roll of the present invention, in order to reversely rotate the take-up shaft, it is not necessary to reverse the rotation direction of the drive motor by the reverse rotation motor or via the clutch mechanism. According to the structure, the gripping portion for gripping can be formed at the end of the film roll with a simple structure and a reliable operation. In particular, since it is not necessary to perform the rotation control of the drive motor of the winding shaft, the accuracy of the operation is improved, and the gripping take-up portion can be surely formed.

According to the reel processing apparatus for a resin film roll of the invention of claim 2, the film roll rotating roller is brought into contact with the film roll at the end of the winding processing position, so that the film roll rotating roll can be easily adjusted to contact the film roll. The speed of time, etc., so as not to give an impact to the film roll without damaging the film roll.

Further, according to the invention, the reel-processed film roll processing device of the invention of claim 3 is capable of holding the roll by restraint even when the plate-shaped roll connecting plate is attached to the end of the film roll and the film roll is rotated. The tail is also unwound from the end of the winding, and the unwinding portion forms the gripping take-up portion, so that the gripping take-up portion is surely formed. Further, since the tail connecting plate is formed of a flat plate, it has a simple structure, and the increase in cost can be suppressed.

Further, according to the invention, the resin film roll end processing device of the invention of claim 4 exerts an appropriate frictional force between the rubber of the tail web and the film sheet, and can reliably restrain the tail with respect to the rotation of the film roll. Thereby, the gripping take-up portion is surely formed. Further, by making the rubber on the inner side soft, it is possible to provide appropriate cushioning properties on the surface of the tail web, and to more reliably restrain the tail. Moreover, since it is hard to use the rubber on the surface side, it is durable with respect to abrasion, and it can be used continuously.

Further, according to the method of processing the resin film roll of the invention of claim 6, the gripping portion for gripping can be formed more reliably, and a resin film roll which is easy to use can be provided to a user.

In the following, a reel processing apparatus for a resin film roll of the present invention will be described with reference to a preferred embodiment of the present invention, and a method for processing a resin film roll and a resin having a roll formed by the treatment method thereof will be described. The film roll and the resin film roll product thereof will be described.

FIG. 4 is a schematic view showing a manufacturing apparatus 1 for a resin film roll which is suitable for the tail processing apparatus 10 including the resin film roll of the present invention. The produced film sheet is taken up, cut into a width supplied to the winding device and shipped, and wound up to be processed into a raw material sheet P, and the raw material sheet P is supplied to the manufacturing apparatus 1. Furthermore, in order to supply the next roll of film manufacture, the sheet material P ₁ prepared in standby.

The film sheet unwound from the raw material sheet P is guided to the turret mechanism 3 as a film roll transfer means while winding a plurality of guide rolls 2 while adjusting the tension or the like. The turret mechanism 3 is sequentially transferred to the paper tube 4 as the take-up shaft supplied from the paper tube hopper 4a as the processing steps are sequentially transferred, and the paper tube 4 is transferred by the rotation of the turntable 3a. On the paper tube 4, the film sheet S guided to the above-mentioned guide roller 2 is taken up to be processed into a film roll R.

In the vicinity of the turntable 3a, a reel processing device 10 for a resin film roll of the present invention is disposed. The tail processing device 10 is mainly composed of a film roll rotating roller 11 and a tail processing device 12 as a winding end processing means.

The film roll rotating roller 11 is rotatably supported by the base end portion so as to be movable at a free end portion of the swing arm 11b that is supported by the swing shaft 11a. By the swing of the swing arm 11b, the film roll rotating roller 11 is moved between the position where it is in contact with the film roll R at the end of the winding end position and the position separated from the space as will be described later. Further, the swing shaft 11a is connected to an output shaft of a drive motor (not shown), and is mounted via a drive pulley 11c and a tension pulley 11d wound around the swing shaft 11a, a film roll rotating roller 11, and a coaxial passive pulley 11e. The drive belt 11f transmits the output of the drive motor to the film roll rotating roller 11.

The above-mentioned tail finishing device 12 is provided with a tail connecting plate 12a which is formed by a long strip of material along the axial direction of the film roll R, and a piston cylinder mechanism 13 which causes the tail connecting plate 12a to be located below The film roll R, which is described in the position of the tail processing, advances and retreats. The above-mentioned tail connecting plate 12a is attached to the front end of the piston rod 13a of the piston cylinder mechanism 13.

The details of the above-described winding finishing device 12 will be described with reference to Figs. 2 and 3 . At the front end of the piston rod 13a, the mounting plate 14 is supported by the spacer mounting block 14a. At the both end portions of the mounting plate 14 in the longitudinal direction, the above-described winding connection plate 12a is attached via a mounting screw 14b. Further, by changing the fastening position of the mounting screw 14b with respect to the mounting plate 14, the position of the tail connecting plate 12a with respect to the piston rod 13a can be adjusted, and the positions of both end portions of the tail connecting plate 12a can be performed. Adjustment. Further, the piston cylinder mechanism 13 is attached to the bracket by fastening a fixing screw (not shown) screwed to the female screw portion 13b to a bracket (not shown), and can adjust the fastening position of the fixing screw. The position of the film roll R in the direction perpendicular to the axis.

The roll connecting piece 12a has a plate shape having a sufficient length to cover the longitudinal direction of the film roll R, and a rubber material is bonded to the surface facing the film roll R. The rubber material is formed in a double shape, and the surface rubber 15a on the front side and the inner rubber 15b on the inner side have different hardnesses, and the surface rubber 15a is harder than the inner rubber 15b. For example, when the Shore hardness of the surface rubber 15a is 50, 60, 72, 81 (A scale, 15 second value), it is preferable to use the combination of the hardness of the inner rubber 15b. Appropriate for 37, 41, 46 (A scale, 15 second value). In addition, the Shore hardness of the surface rubber 15a can be 40 to 90 (A scale, 15 second value), and the Shore hardness of the inner rubber 15b can be 30 to 50 (A scale, 15 second value). combination. Further, it is preferable to use a chloroprene rubber, a urethane rubber, a lanthanum rubber or the like for the surface rubber 15a. However, the material of the surface rubber 15a should also be considered in combination with the material of the film sheet. In the case of the polyvinyl chloride film sheet, the surface rubber 15a is particularly preferably a polyurethane rubber. By using the urethane-based rubber, in the step of forming the gripping take-up portion, the tail is reliably restrained, and the gripping take-up portion is not in contact with the surface rubber 15a and cannot be peeled off during discharge. And the wear resistance is also excellent.

On the other hand, a chloroprene rubber, a urethane rubber, a lanthanum rubber or the like can be used for the inner rubber 15b.

The paper tube 4 is sequentially transferred to the receiving position 41, the roll forming position 42, the tail processing position 43, and the discharge position 44 by the turret mechanism 3. At the receiving position 41, the paper tube 4 supplied from the paper tube hopper 4a is received, and at the roll forming position 42, the film sheet S is taken up to the paper tube 4 to form a film roll R, and at the tail processing position 43 On the other hand, the grip winding portion 20 (shown in Fig. 1) is formed at the end of the winding. The film roll R on which the gripping take-up portion 20 is formed is transferred to the discharge position 44, and then rotated on the transfer plate 5 to be transferred to the next step such as the packaging step.

Hereinafter, the action of the tail processing apparatus of the resin film roll of the present invention configured as described above will be described.

The paper tube 4 supplied from the paper tube hopper 4a is transferred to the turntable 3a of the turret mechanism 3 at the above-mentioned receiving position 41. When the front paper tube 4 forms the film roll R at the above-described roll forming position 42, the front turntable 3a is operated immediately after completion, and the respective paper tubes 4 are transferred to the next position. The film roll R located immediately before completion of the roll forming position 42 is transferred to the tail end processing position 43. In the middle of the transfer, by the cutter (not shown) provided on the turntable 3a, the end portion of the front end of the film roll R, that is, the end of the film, the film sheet S of the front film roll R and the subsequent roll are cut. The film sheet S taken to the next paper tube 4 is separated, so that the rotation of the front paper tube 4 is stopped. The film sheet S of the subsequent portion which has been cut is taken up from the winding head which is the most cut-off portion to the next paper tube 4.

The film roll R having the front face of the roll is formed by cutting with a cutter to be transferred to the tail end processing position 43, and is also rotated by inertia. This is because the inertia force is generated by cutting in order to stretch by cutting the cutter more reliably. Further, at this time, the rotational direction is that the film sheet S is taken up to the forward direction of the paper tube 4.

When the film roll R is located at the winding end processing position 43, the swing arm 11b swings to bring the film roll rotating roller 11 into contact with the film roll R. Thereby, the rotation of the film roll R due to the inertia is stopped. Further, the piston-cylinder mechanism 13 operates to advance the piston rod 13a to bring the winding-end connecting plate 12a into contact with the film roll R. In this state, the film rotating roller 11 is rotated to rotate the film roll R in the reverse direction. Further, the number of rotations at this time is set to be much smaller than the number of rotations when the film sheet S is wound up. The rotation in the opposite direction is the direction in which the film sheet S is unwound from the film roll R. On the other hand, the tail web 12a is in contact with the film roll R, so that the contact portion is rotated with respect to the film roll R. Restricted and thus unwinded by this part. At this time, the surface rubber 15a of the tail connecting plate 12a has a large hardness, and is reversely rotated to the tail and the roll by the difference between the adhesive force of the film roll R and the frictional force between the surface rubber 15a and the film roll R. The tail connecting plate 12a is opposite to each other, and is unwound from the end of the tail when the tail is connected to the tail connecting plate 12a, so that the unwound portion is connected by the tail connecting plate 12a as shown in FIG. Since the movement is prevented, a block is formed at a position abutting on the tail connecting plate 12a, and the block is taken up to form the grip portion winding portion 20.

When the grip portion winding portion 20 of an appropriate size is formed, the film roll R is transferred to the discharge position 44 by the turntable 3a, and is guided to the next step by the transfer sheet 5.

As described above, the grip winding portion 20 is formed in the longitudinal direction of the film roll R on the film roll R manufactured by the resin film roll end processing device. When the film roll R is used, the gripping take-up portion 20 can be easily grasped. When the gripping take-up portion 20 is gripped and unwound, the film sheet S can be easily enlarged and unwound throughout the entire length direction, so that it is not torn at an accidental position, and the usability is improved.

In addition, the completed film roll R is stored in a specific case and shipped as a film for food packaging.
