Description

  The present invention relates to a packaging method and apparatus for packaging an adhesive sheet roll that has an outer peripheral surface as an adhesive surface and is used for cleaning a floor surface and the like.

  As an example of the cleaning tool, there is one using an adhesive sheet roll whose outer peripheral surface is an adhesive surface (see, for example, Patent Document 1). In order to distribute such an adhesive sheet roll as a product in the market, it is necessary to package the adhesive sheet roll so that the adhesive surface is not exposed to the outside.

  Conventionally, when packaging a roll on which a sheet is wound, generally, the following means are often employed. In other words, the roll to be packaged is rotatably supported and arranged at a predetermined location. On the other hand, the packaging sheet is supplied onto the outer peripheral surface of the roll using a conveyor or the like. After the front end of the packaging sheet is supplied onto the outer peripheral surface of the roll, the roll is rotated while pressing the packaging sheet against the outer peripheral surface of the roll using a pressing roller or the like. Thereby, a packaging sheet is wound around the outer peripheral surface of a roll (for example, refer patent documents 2 and 3).

  However, when the adhesive sheet roll is packaged using the above-described means, there are the following problems.

  That is, in the said conventional means, the packaging sheet conveyed by the conveyor etc. is directly supplied on the outer peripheral surface of the roll which is a packaging object. For this reason, when supplying a packaging sheet from a conveyor on the outer peripheral surface of a roll, there exists a possibility that the front-end | tip part of a packaging sheet may bend or shake, and a positional shift may be produced in the front-end | tip part. If the packaging sheet is thin and soft, such a concern is greater. On the other hand, the pressure-sensitive adhesive sheet roll used as a cleaning tool has a substantially adhesive surface with a high adhesive force on the outer peripheral surface thereof. Therefore, when the packaging sheet is supplied from the conveyor to the outer peripheral surface of the pressure-sensitive adhesive sheet roll, a positional shift as described above occurs, and the tip of the packaging sheet comes into contact with a location different from the location where the pressure-sensitive adhesive sheet roll should be supplied. As soon as the leading edge of the packaging sheet is adhered to the pressure-sensitive adhesive sheet roll, wrinkles and distortion are likely to occur in this part. When such wrinkles and distortions occur, the appearance of the package is deteriorated, and it becomes a cause of defective packaging. For this reason, conventionally, when packaging an adhesive sheet roll, the yield is relatively poor, and there is room for improvement in this respect.

By, is characterized in that said packaging sheet has a second step of gradually wound while adhering to the outer peripheral surface of the pressure-sensitive adhesive sheet roll.

According to such a configuration, at least a portion near the leading end of the packaging sheet conveyed by the conveyor is adsorbed to the outer peripheral surface of the suction roller and supplied to the outer peripheral surface of the adhesive sheet roll in a state of being held so as not to be displaced. Unlike conventional packaging means that directly supply the packaging sheet from the conveyor toward the outer peripheral surface of the adhesive sheet roll, the tip of the packaging sheet is appropriately and accurately positioned at a predetermined position of the adhesive sheet roll. It becomes possible to supply. Therefore, it is possible to reduce packaging defects caused by positional deviation of the packaging sheet, and to improve the yield compared to the conventional case.
In addition, according to the present invention, although the suction roller that can move between the conveyance path of the conveyor and the adhesive sheet roll is used, such a suction roller can be provided relatively easily. The overall size and complexity can be appropriately suppressed.

The pressure-sensitive adhesive sheet roll packaging device provided by the second aspect of the present invention is such that the pressure-sensitive adhesive sheet roll whose outer peripheral surface is a pressure-sensitive adhesive surface is rotatably supported and positioned at a predetermined location. An adhesive sheet roll wrapping device for wrapping a wrapping sheet around an outer peripheral surface, a conveyor having a transport path for transporting the wrapping sheet along a fixed path, and a drive rotatable, and approaching the transport path of the conveyor A suction roller provided so as to be able to reciprocate between a position where the adhesive sheet roll approaches and a position approaching the adhesive sheet roll, and when the suction roller approaches the transport path of the conveyor, It is possible to take up at least a portion near the leading end of the packaging sheet conveyed on the road by adsorbing it to the outer peripheral surface of the adsorption roller, and When approaching the trawl is characterized in that the is rotatable in a state in which a packaging sheet that is attracted to the outer peripheral surface is brought into contact with the outer peripheral surface of the pressure-sensitive adhesive sheet roll of the suction roller.
Preferably, the suction roller has an internal space portion that can be set in a negative pressure state, and a plurality of holes that communicate with the internal space portion are provided on the outer peripheral surface. The hole is configured to exert a suction action based on the negative pressure.

  According to such a configuration, the pressure-sensitive adhesive sheet roll packaging method of the present invention can be suitably carried out, and the same effects as described for the pressure-sensitive adhesive sheet roll packaging method of the present invention can be obtained.

  Other features and advantages of the present invention will become more apparent from the following description of embodiments of the present invention with reference to the accompanying drawings.

It is the schematic which shows an example of the packaging apparatus of the adhesive sheet roll which concerns on this invention, and an adhesive sheet roll manufacturing apparatus corresponding to this. It is a partial cross section side view of arrow II of the adhesive sheet roll manufacturing apparatus shown in FIG. (A) is a perspective view of the adsorption | suction roller which the packaging apparatus shown in FIG. 1 comprises, (b) is IIIb-IIIb sectional drawing of (a). (A), (b) is principal part explanatory drawing which shows the state which moves the attraction | suction roller shown in FIG. (A)-(d) is principal part operation | movement explanatory drawing of the packaging apparatus of the adhesive sheet roll shown in FIG.

  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

1-5 has shown an example of the packaging apparatus (henceforth a "packaging apparatus" suitably) of the adhesive sheet roll which concerns on this invention.
As clearly shown in FIG. 1, the packaging device W of this embodiment is used in combination with a manufacturing device 2 for manufacturing the pressure-sensitive adhesive sheet roll 7. The pressure-sensitive adhesive sheet roll 7 is used as a component part of a cleaning tool as described in Patent Document 1. Specifically, the pressure-sensitive adhesive sheet roll 7 has a configuration in which a pressure-sensitive adhesive sheet 71 is wound around a cylindrical core member 70 as shown in FIGS. 2 and 5. The outer surface side of this is an adhesive surface coated with an adhesive.

First, the configuration of the pressure-sensitive adhesive sheet roll manufacturing apparatus 2 will be briefly described.
This manufacturing apparatus 2 is an apparatus that cuts a long adhesive sheet 71 that is a constituent element of the adhesive sheet roll 7 after winding the core sheet 70 around the core sheet 70. More specifically, the manufacturing apparatus 2 includes a rotating plate 21 having a plurality of support shafts 20 and a cutter 22. The plurality of support shafts 20 are portions for supporting the core material 70 of the pressure-sensitive adhesive sheet roll 7, and protrude to one side of the rotating plate 21 and are rotatable as shown in FIG. 2. The rotating plate 21 can rotate in the direction of arrow N1 in FIG. 1 by driving the motor M1. By this rotation, the plurality of support shafts 20 sequentially move to predetermined positions P1 to P6. In the range of positions P2 and P3, the support shaft 20 can be actively rotated by receiving a rotational force from a rotational force applying means (not shown) using a motor or the like. In the position P1, the core member 70 is fitted onto the support shaft 20 (see also FIG. 2). At the position P <b> 3, the support sheet 20 rotates while the long adhesive sheet 71 is supplied onto the outer peripheral surface of the core member 70, whereby the adhesive sheet 71 is wound around the outer peripheral surface of the core member 70. The long adhesive sheet 71 is supplied and guided via a guide roller 29 from, for example, an adhesive sheet take-up roll (not shown). The cutter 22 cuts the adhesive sheet 71 after completing the above-described winding. Thereby, the adhesive sheet roll 7 is manufactured.

  When the adhesive sheet 71 is cut, the rotating plate 21 is rotated in advance in the direction of the arrow N1 by an appropriate angle. As a result, the core material 70 existing at the position P <b> 2 moves closer to the pressure-sensitive adhesive sheet 71, and adheres to a portion of the pressure-sensitive adhesive sheet 71 upstream of the cut portion. As a result, preparation for winding the next pressure-sensitive adhesive sheet 71 around the core material 70 present at the position P2 is made. The adhesive sheet roll 7 manufactured at the position P3 then moves to the positions P4 to P6. At the position P5, packaging described later is performed. At the position P6, as shown in FIG. 2, the adhesive sheet roll 7 that has completed the winding and packaging of the packaging sheet 1 is removed from the support shaft 20.

Next, the configuration of the packaging device W will be described.
As clearly shown in FIG. 1, the packaging device W includes a feeding device 3 for a long packaging sheet 1 </ b> A, a cutter 4, a conveyor 6, and a suction roller 5. The feeding device 3 is a device for feeding a long packaging sheet 1A from a packaging sheet take-up roll R along a fixed path, and is driven and rotated by a plurality of guide rollers 30a to 30c and a motor (not shown). A pair of feeding rollers 31 is provided. The cutter 4 cuts the packaging sheet 1 </ b> A at the subsequent stage of the feeding roller 31. By this cutting, a packaging sheet 1 having a predetermined size suitable for packaging the adhesive sheet roll 7 is obtained.

  The conveyor 6 is for conveying the packaging sheet 1 below the position P5 and the suction roller 5 of the manufacturing apparatus 2, and has an endless belt 61 wound around a plurality of rollers 60a to 60c. . The roller 60a can be driven and rotated by a motor (not shown). The upper horizontal portion of the belt 61 is a conveyance path 62 that carries the packaging sheet 1 and conveys it in the direction of arrow N2. The conveyance path 62 is preferably configured so that the packaging sheet 1 can be conveyed as stably as possible without any positional deviation.

  The suction roller 5 performs the operation of winding around the outer peripheral surface of the adhesive sheet roll 7 at the position P5 after taking out and holding the packaging sheet 1 conveyed by the conveyor 6. The suction roller 5 can be driven and rotated based on the operation of the drive mechanism 8 and can reciprocate in the direction of the arrow N3. The suction roller 5 and the rear part (the most downstream part) of the conveyance path 62 of the conveyor 6 and Can be approached (including contact).

  As shown in FIG. 3, the suction roller 5 has a cylindrical roller body 50 having a pair of shaft portions 51 provided at both ends. At least one of the pair of shaft portions 51 is connected by piping to the intake side of a blower or a pump (not shown), and the internal space portion 52 of the roller body 50 can be set to a negative pressure state. On the outer peripheral surface of the roller main body 50, a plurality of holes 53 that communicate with the internal space 52 are provided. Accordingly, these hole portions 53 exhibit a negative pressure suction action, and the packaging sheet 1 can be adsorbed to the outer peripheral surface of the adsorption roller 5. In the present embodiment, the plurality of hole portions 53 are provided in two rows arranged at appropriate intervals in the axial length direction of the suction roller 5, and the two rows of hole portions 53 sandwich the center of the suction roller 5. They are arranged opposite to each other. Of course, the plurality of hole portions 53 may not be provided in such an arrangement, and the hole portions 53 described above are provided in only one row or three or more rows, and further provided in an arrangement other than the row shape. Thus, the suction roller 5 may be provided so as to be distributed over only a part of the outer peripheral surface or substantially the entire region.

  As shown in FIG. 1, the drive mechanism 8 of the suction roller 5 has a swing arm 80 that supports the suction roller 5 in a rotatable manner, a reciprocating cylinder 81, and a motor M2. The motor M2 is, for example, a servo motor that can rotate in both forward and reverse directions, and the rotational force of the motor M2 is applied to suction rollers via endless belts 83a and 83b such as timing belts wound around pulleys 82a to 82c. 5 is transmitted. As a result, the suction roller 5 can be driven and rotated. The reciprocating cylinder 81 is for swinging up and down the suction roller 5 by swinging the swing arm 80 about a shaft portion 84 at one end in the longitudinal direction. The rod 81a of the reciprocating cylinder 81 is connected to a swing arm 80, and the suction roller 5 swings and moves up and down by the expansion and contraction of the rod 81a. As shown in FIG. 4A, when the suction roller 5 is lowered, the suction roller 5 approaches the conveyance path 62 of the conveyor 6. In this arrangement state, the packaging sheet 1 on the conveyance path 62 can be adsorbed and wound up as will be described later (the packaging sheet 1 is omitted in FIG. 4). On the other hand, as shown in FIG. 4B, when the suction roller 5 is raised, the suction roller 5 is disposed close to the outer peripheral surface of the adhesive sheet roll 7 at the position P5. In this arrangement state, as will be described later, the packaging sheet 1 can be wound around the outer peripheral surface of the pressure-sensitive adhesive sheet roll 7.

  Next, an example of a method for packaging an adhesive sheet roll using the packaging device W described above will be described.

First, when the packaging sheet 1 has been transported near the end of the transport path 62 of the conveyor 6,
As shown in FIG. 5A, the suction roller 5 is lowered, and the outer peripheral surface of the suction roller 5 is brought into contact with the upper surface of the packaging sheet 1 near the front end (portion on the left side of the drawing). Next, the suction roller 5 is driven to rotate while adsorbing the packaging sheet 1 on the outer peripheral surface of the suction roller 5 by utilizing the negative pressure suction action of the hole 53 of the suction roller 5. As a result, the portion closer to the tip of the packaging sheet 1 is wound around the outer peripheral surface of the suction roller 5.

  Next, as shown in FIG. 5 (b), the suction roller 5 is raised, and the portion closer to the tip of the packaging sheet 1 is brought into contact with the outer peripheral surface of the adhesive sheet roll 7. Even in such a contact state, the suction roller 5 is driven to rotate. Accordingly, as shown in FIG. 5C, the suction roller 5 winds up the portion near the rear end of the packaging sheet 1 from the conveyor 6. On the other hand, the adhesive sheet roll 7 is driven to rotate as the suction roller 5 rotates. Moreover, since the outer peripheral surface of the adhesive sheet roll 7 is an adhesive surface, the part of the packaging sheet 1 that is in contact with the outer peripheral surface of the adhesive sheet roll 7 adheres to the adhesive sheet roll 7 and separates from the suction roller 5. . For this reason, as shown in FIG. 5 (d), the full length region or the substantially full length region of the packaging sheet 1 is bonded to the outer peripheral surface of the pressure-sensitive adhesive sheet roll 7 and wound up. When such a winding operation is completed, the suction roller 5 is lowered to enter a standby state for the suction holding operation for the next packaging sheet 1, and the series of operations described above can be repeated thereafter. Preferably, the packaging apparatus W is configured to execute all the series of operations described above by automatic control (program control).

  According to the packaging method as described above, at least a portion near the front end of the packaging sheet 1 conveyed by the conveyor 6 is supplied to the outer peripheral surface of the adhesive sheet roll 7 in a state where it is adsorbed by the adsorption roller 5 so as not to be displaced. Is done. Therefore, it is possible to supply the front-end | tip part of the packaging sheet 1 with respect to the outer peripheral surface of the adhesive sheet roll 7 in the appropriate state without a position shift, an inclination, etc., and a packaging defect can be decreased. As the components of the packaging device W, the suction roller 5 and the drive mechanism 8 are necessary. However, since these configurations are relatively simple, it is possible to suppress the increase in cost and size of the packaging device W as much as possible. It is.

  The present invention is not limited to the contents of the above-described embodiment. The specific configuration of each work process of the packaging method according to the present invention can be variously changed within the intended scope of the present invention. Similarly, the specific configuration of each part of the packaging device according to the present invention can be varied in design in various ways.

  The suction roller only needs to have a function capable of sucking the packaging sheet, and may be other than the negative pressure suction method. When the suction roller is reciprocated between the conveyance path of the conveyor and the adhesive sheet roll, the suction roller 5 is moved along a linear locus instead of being supported by the swing arm 80 and moved along an arc locus. It can also be moved. The conveyor referred to in the present invention may be any conveyor as long as it can transport the packaging sheet along a certain route, and can be a conveyor other than the belt conveyor. The specific material and size of the packaging sheet are not limited. Further, the pressure-sensitive adhesive sheet roll to be packaged is a pressure-sensitive adhesive sheet roll whose outer peripheral surface is a pressure-sensitive adhesive surface, and may not be used as a cleaning tool. In the present invention, in a state where the pressure-sensitive adhesive sheet roll is rotatably supported, the packaging sheet is wound around the pressure-sensitive adhesive sheet roll, but the place where the pressure-sensitive adhesive sheet roll is supported is not particularly limited, You may make it wind a packaging sheet in the state which supported the adhesive sheet roll in the location different from a manufacturing apparatus.
