Description

  The present invention relates to a film packaging apparatus and a film packaging method for a roll assembly. More specifically, the present invention relates to a film wrapping apparatus and a film wrapping method for wrapping a roll assembly in which a plurality of winding rolls are inserted into a core and assembled in one set for the purpose of dust prevention.

  When a belt-like film is used industrially, it is very convenient in a mass production process because it can be continuously fed out in a subsequent process if it is wound on a winding roll. When this strip-shaped film is transported to a post-process as a semi-finished product or transported to another factory where it is incorporated into a finished product, if contamination of dust or dust affects the quality of the finished product, it is wound as a semi-finished product. It is necessary to film the take-up roll to prevent dust and dirt from entering.

  When packaging this film, in order to improve the transportation efficiency and the packaging process, a plurality of winding rolls are inserted into the same core to form a single roll assembly, and the roll assembly is packaged with a film having dust resistance. I was trying to do it. The following patent documents 1 and 2 are mentioned as a prior art example regarding such a film packaging technique.

In Patent Document 1, a plurality of roll assemblies in which circular protection plates larger than the product winding diameter are arranged on both end surfaces (circular surfaces) are stacked concentrically on a pallet so that the axial direction is vertical. After that, a method is described in which a stretch film is wound around the entire outer periphery, and coated and packaged integrally therewith. However, a packaging device for winding the stretch film around the roll assembly is not disclosed.
Patent Document 2 discloses a packaging method in which a plurality of rolls obtained by winding a tape around a cylindrical core material are used as a single roll assembly through a central core, and the outer periphery of the roll assembly is covered with a light-shielding sheet. Are listed. However, this patent document 2 also does not disclose a packaging device that covers the roll assembly with a light-shielding sheet.

As mentioned above, since there was no suitable packaging device in the past, the work of assembling a plurality of take-up rolls on the core was also done manually, and the work of packaging the assembled roll assembly was also done manually. I had no choice but to do it.
However, these methods are very inefficient, and involve the danger of dust and the like adhering to the operator's hair and clothes.

Next, an embodiment of the present invention will be described with reference to the drawings.
A winding roll R shown below is obtained by winding a belt-like film used for a battery separator or the like around a winding core, but the present invention is not limited to this and is applied to various winding rolls. be able to.

First, based on FIG. 1 and FIGS. 2-3, the basic composition of the packaging apparatus of this invention and the basic procedure of the packaging method are demonstrated.
1 indicates a supply station, and Im in FIG. 2 indicates a supply process. The supply station I is composed of a conveyor 10, and sequentially carries the winding rolls R one by one to the end of the conveyor 10, and executes a supply process Im for supplying the winding rolls R to the assembly station II.

  Reference numeral II in FIG. 1 indicates an assembly station, and reference numeral IIm in FIG. 2 indicates an assembly process. In the assembly station II, a core stocker 12, a protective sheet stocker 20, and a spacer stocker 30 are attached. In this assembling station II, the core 1 is assembled into a roll assembly RA by inserting a protective sheet 2a at one end, several winding rolls R and spacers 3 alternately, and another protective sheet 2b at the other end. Step IIm is performed.

  Reference numeral III in FIG. 1 indicates a body winding station, and reference numeral IIIm in FIG. 3 indicates a body winding process. At the body winding station III, a body winding process IIIm is performed in which the outer periphery of the roll assembly RA is wrapped in a cylindrical shape with a packaging film. In this process, the outer peripheral surface of the body portion of the roll assembly RA is wound in a cylindrical shape with a packaging film, and the longitudinal direction of the cylindrical packaging film is sealed, and the cylindrical film body CF that is open at both ends is opened. It is formed.

Reference numeral IV in FIG. 1 indicates a sealing station, and reference numeral IVm in FIG. 3 indicates a sealing process. At the sealing station IV, a sealing step IVm is performed in which both ends of the tubular film CF are twisted to form a twisted portion tw, and a tape tp is further applied to fix the twist.
Reference numeral V in FIG. 1 denotes a dispensing station, which is constituted by a known conveyor. With this conveyor, the packaged roll product WR that has been packaged is dispensed.

  According to the packaging apparatus and the packaging method of the present invention, the film packaging operation of automatically assembling the take-up roll R into the roll assembly RA according to the above procedure and then sealing it with the packaging film to form the packaged roll product WR is automatically performed. Can be done.

Below, the film packaging apparatus Z which concerns on one Embodiment of this invention is demonstrated in detail.
As shown in FIG. 4, the film packaging apparatus Z of the present embodiment has two conveyors 10 installed in parallel, and a supply station I is configured by the two conveyors. Thus, the efficiency is improved by using two supply lines. However, this is not an essential requirement of the present invention. One supply line may be used, and the supply station I may be constituted by three or more conveyors.
The conveyor 10 only needs to be able to individually and sequentially convey the take-up rolls R, and may have any configuration such as a conveying plate type, a belt type, or a roller type.

As shown in FIG. 4, the center core stocker 12 attached to the assembly station II is installed between the two conveyors 10 and 10.
As shown in FIG. 5, the core stocker 12 is provided with a chute 14 that is inclined obliquely at the bottom of a box-shaped storage portion 13, and two movable stoppers 15 a and 15 b are arranged in series at the tip of the chute 14. It is a thing. A large number of cores 1 are stored in the storage unit 13, and several cores 1 descend the chute 14 in a state where they are aligned in parallel. When the two movable stoppers 15a and 15b are alternately raised and lowered, the cores 1 can be cut out one by one. If the cores 1 are stored and can be cut out one by one, a core stocker having a structure other than that shown in the figure may be used.

  A delivery lever 16 is mounted on the floor near the tip of the chute 14 so as to be swung by an air cylinder 17. A single core 1 is placed on a receiving portion 16a of the delivery lever 16, and leftward in the figure. When moving to, the core 1 can be replaced on the assembly 18. The assembly base 18 is provided with a push mechanism (not shown) so that the core 1 can be mounted on the core support mechanism 40 described later.

  FIG. 4 shows a protective sheet stocker 20 and a spacer stocker 30 attached to the assembly station II. Each stocker 20 and 30 is provided in two rows corresponding to the conveyor 10. In addition, when the conveyor 10 is provided in three or more rows, it is good to correspond to this and to increase the number of arrangement | positioning of each stocker 20,30.

As shown in FIG. 6, the protective sheet stocker 20 has two pairs 20A and 20B. One stocker 20A is for the lower protective sheet 2a during assembly (see FIG. 2), and the other stocker. 20B is for the protective sheet 2b which is the upper side during assembly (see FIG. 2). In any of the stockers 20A and 20B, a support bar 21 is set up, and a large number of protective sheets 2a and 2b are inserted therein. The stockers 20A and 20B increase the protective sheets 2a and 2b up to the upper end of the support bar 21 as the number of held sheets increases so that the protective sheet 2a and 2b can be easily held by a hand mechanism described later. It is advisable to attach an elevating mechanism for lowering.
The protective sheet stocker 20 in the present invention only needs to be able to store and take out the protective sheets 2a and 2b, and a structure other than that illustrated may be used as long as it can perform such a function.

The spacer stocker 30 has a holding rod 31 and is a stocker in which a large number of spacers 3 are inserted and stored in a stacked state. It is preferable that this stocker 30 is also provided with an appropriate lifting mechanism so that only the uppermost spacer 3 can be easily grasped by a hand mechanism 50 described later.
The spacer stocker 30 only needs to be able to store and take out the spacer 3, and a structure other than that illustrated may be used as long as such a function can be achieved.

Next, the core support mechanism 40, the hand mechanism 50, and the delivery mechanism 60 constituting the assembly station II will be described in order.
As shown in FIG. 6, the core support mechanism 40 is attached to a swing shaft 42 in which a vertical support pin 41 is provided horizontally, and the swing shaft 42 swings with arbitrary power such as an air cylinder. It is like that. In FIG. 6, the support pin 41 stands vertically, but when the swing shaft 42 is rotated, the support pin 41 falls horizontally (toward the back of the page). When the support pin 41 is tilted horizontally, the support pin 41 is positioned on the upper surface of the assembly base 18 shown in FIG. 5. Therefore, when the core 1 previously placed on the assembly base 18 is pushed by a push mechanism (not shown) in this state, the support pin 41. The core 1 can be extrapolated. Thereafter, when the support pin 41 is erected, as shown in FIG. 6, the core 1 is held by the upright support pin 41 and stands vertically.
In this state, the winding roll R, the protective sheets 2a and 2b, and the spacer 3 are assembled to the core 1 as described later.
In the present invention, the core support mechanism 40 only needs to be able to assemble the winding roll R, the protective sheets 2a, 2b, and the spacer 3 to the core 1, and if it can perform such a function, a mechanism other than that shown in the drawing is used. It may be used.

  The hand mechanism 50 shown in FIG. 6 attaches the winding roll R and the like described above. The hand mechanism 50 includes an air cylinder 51 that expands and contracts vertically and a slide mechanism 52 that traverses the air cylinder 51. The slide mechanism 52 is preferably a mechanism in which a screw rod is rotated by a servo motor to traverse, since the traversing position can be accurately controlled. A chuck 53 is attached to the tip of the rod of the air cylinder 51. The chuck 53 only needs to be able to grip the take-up roll R, the protective sheets 2a and 2b, and the spacer 3, and various types can be used such as a chuck or a gripper.

  Using the hand mechanism 50, when the lower protective sheet 2a is first grasped by the chuck 53 and conveyed onto the core 1 to release the chuck 53, the protective sheet 2a can be inserted into the lower portion of the core 1. Similarly, the winding rolls R and the spacers 3 are alternately grasped and conveyed, and inserted into the core 1. When this process is repeated several times and finally the upper protective sheet 2b is grasped and conveyed and inserted onto the core 1, the roll assembly RA is formed as a set of five winding rolls as shown in FIG. Attached.

  In FIG. 6, only one hand mechanism 50 is shown, but if two are equipped, one is for the take-up roll R, and the other is for the protective sheets 2 a, 2 b and the spacer 3. Thus, the roll assembly RA can be assembled with higher efficiency.

  The delivery mechanism 60 will be described with reference to FIG. The feed mechanism 60 includes a swing lever 61 and an air cylinder 62 (only the rod portion is shown) that drives the swing lever 61, and the swing lever 61 has a gripping mechanism that holds the roll assembly RA. When the roll assembly RA is tilted sideways from the state where it is assembled upward as shown in FIG. 6 (toward the back of the paper surface), it can be grasped by the rocking lever 61. When moved to the left in the figure, the roll assembly RA can be sent out on the feed base 63. In addition, as long as the roll assembly RA can be sent out to the next process side, the sending mechanism 60 may be configured by a mechanism other than the illustrated one.

Next, the body winding station III will be described with reference to FIGS. The body winding station III includes a spreading mechanism 70, a pushing mechanism 80, and a seal cutting mechanism 90.
The stretching mechanism 70 is mainly composed of a roll device 71 for supporting the original roll Fr of the packaging film F provided at the upper stage of the station, an accumulator 72 for storing the unwinding amount of the film F, and a film provided at the lower stage of the station. It comprises a drive roll 73 for winding. Note that guide rolls 74 are provided at various points in the film feeding path to guide the feeding of the film F.

In this spreading mechanism 70, when the packaging film F is unwound from the raw roll Fr by the roll device 71, the film F for one packaging is stored in the accumulator 72. Further, the film F extending from the accumulator 72 is stretched from the upper side to the lower side along an opening surface of a body winding space 83 described later in the previous packaging process. The accumulator 72 functions to keep the tension constant when the packaging film F is pushed into the body winding space 83 as will be described later.
Since the film stretching by the stretching mechanism 70 is performed for preparation of a body winding process described later, the stretching mechanism 70 may be configured by using a mechanism other than that shown in the drawing as long as the body winding process can be prepared.

  The pushing mechanism 80 provided in the drum winding station III includes a pusher 81 and its driving device (not shown), a drum winding space 83 provided in the drum winding station III, a table 84 at the bottom thereof, and a pushing bar 85 for the film F. Is done. The body winding space 83 is open on the right side in the drawing, that is, on the assembly station II side. The push-in bar 85 is a bar that is provided so as to be movable from the front to the back of the body winding space 83, and is arranged apart from each other at both end positions of the film F. An arbitrary actuator such as an air cylinder is used as the moving means. 7 is a state where the film F is positioned on the front surface of the body winding space 83. In FIG. 8, the state illustrated by the solid line is a state where the film F is pushed into the body winding space 83. The film F is adapted to wrap the roll assembly RA.

  As shown in FIG. 7, after the film F is pushed into the drum winding space 83, the roll assembly RA placed on the feed base 63 of the assembly station II is pushed to the left side in the drawing by the pusher 81. The roll assembly RA can be pushed onto the inner table 84. As the pushing mechanism 80, any mechanism may be used as long as the roll assembly RA can be pushed into the body winding space.

The body winding method performed after the above state will be described with reference to FIG.
As shown in FIG. 8 (A), the packaging film F in a state of being pushed in by the push-in bar 85 is regulated by guide rolls 86 and 86 provided above and below the opening surface of the body winding space 83. Is in a state of covering the outer surface corresponding to the upper surface, the rear surface, and the lower surface of the body of the roll assembly RA.

  As shown in FIG. 8B, the seal cut mechanism 90 includes an upper sealer 91 and a lower sealer 92 provided at the upper and lower portions in the opening of the body winding space 83. Both the upper sealer 91 and the lower sealer 92 have heat seal portions 94 on both the front and rear sides and a cutter 95 provided at the center. Both the upper sealer 91 and the lower sealer 92 can be moved up and down, but the upper sealer 91 can be moved up and down, the lower sealer 92 can be fixed, the upper sealer 91 can be fixed, and the lower sealer 92 can be moved up and down. . In addition, a pressing member that does not generate heat may be disposed outside each heat seal portion 94 so that the film is not melted by heat while the films are closed.

As shown in FIG. 8B from the state of FIG. 8A, when the upper sealer 91 is lowered and the lower sealer 92 is raised, the two packaging films F are closed on the front surface of the roll assembly RA, and When the sealers 91 and 92 are combined, the packaging film F is heat-sealed by the seal portions 94 and 94 at the two left and right portions, and the space between them is cut by the cutter 95.
Then, as shown in FIG. 8C, there are two heat sealing portions S1 and S2, and the heat sealing portion S1 finishes the packaging film F wound around the roll assembly RA into a cylindrical film body CF. In this state, the outer periphery of the body of the roll assembly RA is in a state of being wound in a cylindrical shape with the packaging film F, and only both ends are open.

  On the other hand, since the heat sealing part S2 joins the upper and lower packaging films F, F, if the packaging film F is pulled downward by the drive roll 73 (see FIG. 7) described above, the packaging film F can be expanded again. it can. Moreover, since the heat seal portion S2 is positioned below the body winding space 83, the roll assembly RA can be wrapped with the film F without the connection portion in the next packaging.

  The seal cut mechanism 90 in the present invention may be any mechanism as long as it can cut and seal the wound film from the stretched film and seal the cut film so that it can be stretched again.

The seal station IV will be described with reference to FIGS. The seal station IV includes a twisting mechanism 100 and a tape applying mechanism 110.
As shown in FIG. 9, the twist mechanism 100 has a pair of left and right disposed at both ends of the cylindrical film body CF. Each torsion mechanism 100 includes a chuck 101 that grips the outermost end of the cylindrical film body CF, and a holder 102 that rotatably holds a portion inside the outermost end. The holder 102 only needs to have a function of lightly restraining the twisted portion with two or several claws so as not to swing and closing the end portion in the open state. The chuck 101 is a member that firmly holds and rotates the end of the closed cylindrical film body CF. For this reason, the rotating shaft 103 and the motor 104 as a driving source are connected to the chuck 101.

When both ends of the cylindrical film body CF are lightly held by both the left and right holders 102 shown in FIG. 9, and then both ends are gripped and rotated by the chuck 101, both ends of the cylindrical film body CF are shown in FIG. 3 (IVm). It is possible to make a twisted part tw that is twisted.
The twist mechanism 100 may be any mechanism as long as both ends of the tubular film body CF can be twisted.

  As shown in FIG. 10, the tape attaching mechanism 110 is provided in a pair of left and right below the left and right twist mechanisms 100. The pair of left and right tape attaching mechanisms 110 may be moved in the width direction (left and right direction in FIG. 10) with a screw rod 111 with a motor so that the position can be adjusted to both ends of the tubular film CF, or manually moved. It may be possible to adjust the position. Further, it may not be movable and cannot be adjusted in position.

Next, a tape application operation by the tape application mechanism 110 will be described.
FIG. 11A is a side view of the main part of the tape attaching mechanism 110, and each tape attaching mechanism 110 mainly includes an original fabric roll attaching part 112 of the adhesive tape tp and an end holding part 113 of the adhesive tape tp, And a swing guide 114 disposed in the feeding path of the adhesive tape tp.
FIG. 11A shows a non-working position of the tape attaching mechanism 110, which is located below the cylindrical fill body CF supported by the twisting mechanism 100. FIG. From the illustrated position, the original roll mounting portion 112, the terminal holding portion 113, and the swing guide 114 can be lifted by an appropriate lifting mechanism, and swingable to the right side in FIG. 11 (upward in FIG. 10). It has become. In addition, the swing guide 114 can be swung counterclockwise by an appropriate link mechanism.
Further, while these are operating, the tape tp is fed out from the original roll mounting portion 112.

  At the time of work, the tape attaching mechanism 110 is lifted from the non-working position as shown in FIG. 11B, and the adhesive tape tp between the terminal holding part 113 and the swing guide 114 is twisted part of the cylindrical film body CF. Touch tw. Next, as shown in FIG. 12C, when the entire tape applying mechanism 110 moves slightly upward as indicated by an arrow a, the adhesive tape tp is wound around the half circumference of the twisted portion tw. When the swing guide 114 swings counterclockwise as shown in FIG. 4D, the adhesive tape tp between the swing guide 114 and the terminal holding portion 113 is completely wound around the twisted portion tw. In this way, when the adhesive tape tp is wound around the outer periphery of the torsion part tw or more and bonded, the adhesive tape tp is cut by a cutter (not shown) built in the recess of the tip of the swing guide 114, and a new tape terminal is held by the terminal. Held by the unit 113.

As the tape applying mechanism 110, any mechanism may be used as long as the tape can be applied to the twisted portion tw.
Moreover, since both ends of the cylindrical film body CF can be sealed and do not need to be easily unwound, heat sealing may be performed in a flat state without forming the twisted portion tw. In this case, a twisting mechanism is not necessary, and a heat seal mechanism that performs heat welding with both ends of the tubular film body CF interposed therebetween may be used instead of the tape attaching mechanism.

  FIG. 3 (IVm) shows a tubular film body CF attached with a tape. In this way, when the tape tp is applied to the twisted part tw, the twist is fixed, the original part does not return, and the end part of the tubular film body CF does not open.

  In FIG. 4, reference numeral 120 denotes a conveyor, which constitutes a dispensing station V. The conveyor 120 may be any type of conveyor as long as it can dispense the packaged roll product.
