Description

  The present invention relates to an apparatus for producing a masking sheet roll with an adhesive tape, and more specifically, with an adhesive tape for producing a roll wound with a predetermined length in a folded state with a sheet with an adhesive tape preventing adhesion and scattering of paint. The present invention relates to a masking sheet roll manufacturing apparatus.

  The masking sheet roll with an adhesive tape is a roll formed by folding a polyethylene film with an adhesive tape on one side into a long shape. This masking sheet roll with adhesive tape is used as follows.

  For example, when painting a building or the like, the masking sheet roll with adhesive tape is cut to an appropriate length, and the adhesive tape is affixed to the boundary between the painted surface and the non-painted surface, fixed, and folded. The used sheet is extended to cover the non-painted surface. Thereby, generation | occurrence | production of the stain | pollution | contamination of the non-coating surface by a scattering paint can be prevented.

   An apparatus for manufacturing a masking sheet roll with an adhesive tape used for such a purpose is disclosed in Japanese Patent Application Laid-Open No. 63-319127 under the name of “manufacturing apparatus for an adhesive tape film” and is already well known. It has been. The manufacturing apparatus of the film with an adhesive tape of the invention disclosed in this publication is configured as follows.

 That is, the apparatus for producing a film with an adhesive tape includes a primary folding part that folds a continuous cylindrical film that is continuously fed into a half in the width direction, and a secondary folding part that further folds the film into three. The edge part of the elongate film which passed this secondary folding part is provided with the cutter part which can cut | disconnect the edge part of a long film with a cutter to a longitudinal direction, and can expand | deploy to one sheet | seat.

 Furthermore, the manufacturing apparatus of this film with an adhesive tape is the adhesive tape which joins continuously about the edge part obtained by tearing the edge part of a long film with a cutter part in parallel about the width direction of an adhesive tape in parallel. The joint is provided at the final stage of the manufacturing process.

  The film with an adhesive tape manufactured by such an apparatus for manufacturing a film with an adhesive tape is wound around a core material and used for the applications described above.

 By the way, when manufacturing such a film with an adhesive tape, the cylindrical long film supplied normally uses a polyethylene film, and is previously wound in a roll shape. Those skilled in the art generally refer to this as an original roll.

  When such a film with an adhesive tape is produced by a conventional apparatus for producing a film with an adhesive tape, the thickness of the polyethylene film itself is inherently uneven. When rolled up into a roll, there is a problem that the peripheral surface is often bumpy without being formed into a beautiful circular ring shape, which is very unsatisfactory in appearance and lowers the commercial value. This is due to the fact that the conventional apparatus for producing a film with an adhesive tape does not have a technical idea that the long sheet is sufficiently pulled during the folding operation to take up the thickness unevenness of the long sheet and make it easy to wind. It is.

   In order to solve the above-mentioned conventional problems, as disclosed in Japanese Laid-Open Publication No. 10-36793 (published on February 10, 1998), a cylindrical long sheet is rolled into an original roll. When it is wound up and rolled into a roll shape through processes such as continuous feeding and feeding and folding in the width direction, the peripheral surface does not become uneven and becomes a beautiful circular ring shape A masking sheet roll with adhesive tape that has a very good appearance and high commercial value can be obtained, and after folding the long sheet, the crease is further stabilized, and the left and right ends of the long sheet are neatly aligned. The present invention provides a manufacturing apparatus capable of accurately bonding an adhesive tape and further improving the productivity by increasing the production speed.

  Details thereof can be easily confirmed by looking at the above-mentioned Japanese publication gazette and Japanese Patent Laid-Open No. 10-36793 (published on Feb. 10, 1998). Here, the simple structure will be described.

The masking sheet roll manufacturing apparatus with an adhesive tape disclosed in the above-mentioned JP-A-10-36793 (published on February 10, 1998)
(1) In a masking sheet roll manufacturing apparatus with an adhesive tape that is manufactured into a roll in which a masking sheet with an adhesive tape that prevents adhesion and scattering of paint is folded and wound up by a predetermined length, it is cylindrical and long.

(3) a second suspension body including at least two support rollers that pass through and support the long sheet fed from the first folding portion;
(4) The long sheet passing through the second suspension body and folded into two or three at the first folding portion is further folded into two or three continuously along its substantially longitudinal center line. A second folding part to be folded,
(5) a third suspension body including at least three support rollers for passing the long sheet fed from the second folding portion and supporting the long sheet;
(6) A cutter portion that tears an edge of the long sheet that has passed through the third suspension body in the longitudinal direction and can be developed into one sheet;
(7) A pair of pinch rollers that are arranged on the downstream side of the cutter unit and feed out the long sheet from the sheet supply unit so as to pull the long sheet,
(8) a joining roller that passes through the pair of pinch rollers and is continuously joined by overlapping an adhesive tape in parallel on the edge of the long sheet obtained by being cut by the cutter unit;
(9) including a winding unit that winds the masking sheet with an adhesive tape that has come out of the joining roller to a cylindrical core by a predetermined length to form a roll,
(10) The two support rollers of the first suspension body, the two support rollers of the second suspension body, and the three support rollers of the third suspension body are arranged at a considerable interval,
(11) Further, at least one of the pair of pinch rollers is a driving roller driven by a motor.

  And according to the masking sheet roll manufacturing apparatus with an adhesive tape of Unexamined-Japanese-Patent No. 10-36793 which has the structure mentioned above, it has the following effects.

That is, according to the masking sheet roll manufacturing apparatus with adhesive tape disclosed in Japanese Patent Application Laid-Open No. 10-36793, a cylindrical long sheet is continuously fed out from the original fabric roll and fed in the width direction while being fed. When it is finally wound up into a roll shape, the peripheral surface does not become uneven and becomes a beautiful circular ring shape, which is very attractive and obtains a masking sheet roll with adhesive tape that has a high commercial value be able to. By placing a rotating roll as a guide for introduction just before the folding part that folds the long sheet, the friction between the guide and the long sheet can be reduced, so the feeding speed of the long sheet is increased. This can improve productivity. In addition, since the adhesive tape can be joined to the long sheet in a natural state, there is no sagging, warping, stretching, etc. on the adhesive tape part, and masking with a highly valuable adhesive tape that has a very beautiful circumferential surface. There exists an effect that a sheet roll can be obtained.
JP-A 63-319127 JP-A-10-36793

  By the way, in the masking sheet roll manufacturing apparatus with pressure-sensitive adhesive tape disclosed in the above-mentioned JP-A-10-36793, the masking sheet with pressure-sensitive adhesive tape coming out from the joining roller shown in the component (9) is predetermined on the cylindrical core. In the winding unit that winds up the length and turns it into a roll, when the masking sheet with the adhesive tape is wound on the core material for a predetermined length at the winding unit, the excess masking sheet with the adhesive tape is cut, The roll is automatically removed from the winding unit, and then a new core material is inserted, and the tip of the masking sheet with the adhesive tape is again wound around the core material.

  That is, a masking sheet with an adhesive tape is wound around a single core material to form a roll, and then the single masking sheet roll with an adhesive tape is removed from the winding portion, and then a new core is formed. A material is attached to a winding part, and the masking sheet with an adhesive tape is wound around the core material by a predetermined length.

  For this reason, in the masking sheet roll manufacturing apparatus with adhesive tape disclosed in the above-mentioned JP-A-10-36793, when one masking sheet roll with adhesive tape is completed, it immediately adheres to the next new core material. Rather than the continuous process of winding the masking sheet with tape for a predetermined length, the roll is once removed from the winding unit, and a new core material is attached to the winding unit again. Since the process of winding the masking sheet with the adhesive tape by a predetermined length is performed, the production efficiency for one masking sheet roll with the adhesive tape does not increase.

  In view of the above-mentioned circumstances, the present invention continuously wraps a masking sheet with an adhesive tape around different cores, thereby further improving the production efficiency of the masking sheet roll with an adhesive tape. It aims at providing a sheet roll manufacturing apparatus.

  In order to solve the above-described problems, in the present invention, a masking sheet with an adhesive tape that prevents adhesion and scattering of paint is folded, and a masking sheet with an adhesive tape that is wound into a roll by winding a predetermined length at a winding portion. In the roll manufacturing apparatus, the winding unit is a disk body in which four core material support shafts for supporting the core material are rotatably arranged at a predetermined pitch along a circumferential direction, The disc body has a core attachment position A where a new core is attached to the core support shaft, and a winding position B where the tip of the masking sheet with adhesive tape is brought into close contact with the core and wound into a roll. And an outer shape shaping position C for shaping the outer shape of the adhesive tape of the masking sheet roll with adhesive tape wound in a roll shape, and the masking sheet roll with the adhesive tape having the outer shape shaped. A disc body rotating at a predetermined timing to a roll removing position D to be removed from the shaft, and a tip of the masking sheet with the adhesive tape are brought into close contact with the core material at the winding position B of the disc body, and an extra A sheet adhesion and cutting means for cutting the masking sheet with adhesive tape, and an outer shape for shaping the outer shape of the adhesive tape by press-contacting the adhesive tape outer surface of the masking sheet roll with the adhesive tape at the outer shape shaping position C At least the shaping roller means and the roll removing means for holding the masking sheet roll with adhesive tape and removing the masking sheet roll with adhesive tape from the core support shaft at the roll removal position D are provided.

    According to the above-described masking sheet roll manufacturing apparatus with an adhesive tape to be manufactured into a roll, after completing a single masking sheet roll with an adhesive tape at the winding position B of the masking sheet with an adhesive tape in the disc body, When the plate body is rotated, the new core material attached at the core material attachment position A is immediately positioned at the winding position B of the masking sheet with the adhesive tape in the disk body, so that the next new core material is immediately On the other hand, it is possible to continuously wrap the masking sheet with adhesive tape around different core materials, such as winding the masking sheet with adhesive tape for a predetermined length. Efficiency can be further improved.

  In addition, in the Example of this invention shown in FIG. 1, compared with the masking sheet roll manufacturing apparatus with an adhesive tape described in Unexamined-Japanese-Patent No. 10-36793 (published February 10, 1998), it is the 3rd suspension body. And the second folding part are omitted, but the overall basic structure is the same. Therefore, even in the masking sheet roll manufacturing apparatus 1 with an adhesive tape of this embodiment, Japanese Patent Laid-Open No. 10-36793 Similarly, when the long sheet 3 is continuously unwound from the cylindrical raw roll 2 and is folded in the width direction while being fed, it is finally wound up into a roll shape. A masking sheet roll with a pressure-sensitive adhesive tape can be obtained which has a beautiful circular ring shape without any irregularities and has a very good appearance and high commercial value.

  In FIG. 1, reference numeral 100 denotes a control device that controls the overall operation of the masking sheet roll manufacturing apparatus 1 with adhesive tape, and reference numeral 200 denotes an adhesive tape supply unit described later.

  In FIG. 1, reference numeral 50 denotes a cylindrical masking sheet roll with an adhesive tape in which the tip of the masking sheet 20 with an adhesive tape is brought into close contact with the core material 21 at a winding position B of a disk body to be described later. , A sheet adhesion and cutting means for cutting the excess masking sheet 20 with adhesive tape, reference numeral 60 is an outer shape shaping position C to be described later, and is pressed against the adhesive tape portion of the masking sheet roll with adhesive tape, An outer shape shaping roller means 70 for shaping the outer shape of the sheet, and a reference numeral 70 denotes a masking sheet roll with an adhesive tape whose outer shape is shaped, and removes the masking sheet roll with an adhesive tape from the core support shaft at the roll removal position D described later It is a roll removing means.

  On the other hand, the masking sheet roll manufacturing apparatus 1 with an adhesive tape of the present application comes out from the joining rollers 17 and 18 shown in FIG. 1 of the present application, as compared with the masking sheet roll manufacturing apparatus with an adhesive tape disclosed in Japanese Patent Laid-Open No. 10-36793. The structure of the winding part 30 for winding the masking sheet with adhesive tape 20 on a cylindrical core material 21 by a predetermined length and forming it into a roll shape is completely different.

  Next, the winding unit 30 according to the present invention will be described in detail.

As shown in FIG. 1, the winding unit 30 includes a disk body 32 that rotates around a shaft center 31 at a predetermined timing in a clockwise direction as indicated by an arrow.

  On one side surface of the disk body 32, four core material support shafts 40, 41, 42, and 43 for supporting the cylindrical core material 21 have a predetermined pitch (circular in the embodiment) along the circumferential direction. The pitch is 90 degrees along the circumferential direction).

  And this disc body 31 is a core material attachment which attaches the new core material 21 with respect to each core material support shaft 40,41,42,43 via the control signal of the control apparatus 100, and the drive means mentioned later. For the position A, the winding position B where the tip of the masking sheet 20 with adhesive tape is brought into close contact with the core material 21 and winding it into a roll, and the adhesive tape of the masking sheet roll with adhesive tape wound into a roll Rotate at a predetermined timing to an outer shape shaping position C for shaping the outer shape and a roll removal position D for removing the masking sheet roll with adhesive tape having the shaped outer shape removed from the core support shafts 40, 41, 42, 43. It is configured as follows.

  The disk body 32 described above is supported at the tip of the drive shaft 33 disposed on the shaft center 31 as shown in FIG. Since the structure of the core material support shafts 40, 41, 42, 43 is the same, in FIG. 2, for convenience of explanation, the structure of only the core material support shaft 41 is described in detail, and the other core material support shafts 40, Description of the detailed structure of 42 and 43 is abbreviate | omitted.

  The drive means for driving the disc body 31 includes the drive shaft 33 described above, a driven gear 46 fixed to the rear end of the drive shaft 33, and a pinion gear 48 of the drive motor 49 that meshes with the driven gear 46. When the drive motor 49 is actuated, the drive shaft 33 rotates via the pinion gear 48 and the driven gear 46, and the disc body 32 has a predetermined direction in one direction (the clockwise direction of the arrow shown in FIG. 1). It is rotated by a rotation angle (90 degrees).

  On the other hand, the drive means for driving the core support shafts 40, 41, 42, 43 described above is described as representative of the drive means for the core support shaft 41. On the other hand, it is composed of a gear transmission means 45 that is rotatable.

  The gear transmission means 45 includes a drive gear 47 that is integrally formed coaxially, and a driven pulley 34 is supported at the rear end of a shaft that supports the drive gear 47. A cocked belt (not shown) is wound around the driven pulley 34, and the cocked belt is rotationally driven by a driving motor (not shown).

On the other hand, the core material support shaft 41 includes a tip-breaking core material insertion shaft 41a that is inserted and supported by a single core material 21 (FIG. 1) made of a cylindrical body, and the core material insertion shaft 41a. A chucking member 41b that opens and closes the tip and fixes the core material 21 fitted to the fitting shaft 41a and releases the core material 21, rotation of the fitting shaft 41a, and regulation thereof. The driven gear 41d is fixed to the rear end of the core material insertion shaft 41a, and the driven gear 41d meshes with the drive gear 47 of the gear transmission means 45.

  The other core material support shafts 40, 42, and 43 are different only in their mounting positions on the disc body 32, and the structures thereof are the same as described above, and thus detailed description thereof is omitted.

  According to the driving means for driving the core support shaft 41 described above, when a drive motor (not shown) is driven to rotate based on a control signal from the control device 100 (FIG. 1), the cocked belt and the driven pulley 34 (not shown) are used. As a result, the drive gear 47 rotates.

  When the drive gear 47 rotates in this way, the core material insertion shaft 41a also rotates simultaneously via the driven gear 41d that meshes with the drive gear 47. The rotation is controlled by the electromagnetic clutch 41c, and the electromagnetic When the clutch 41c is turned on, the core material insertion shaft 41a rotates following the driven gear 41d. When the electromagnetic clutch 41c is OFF, the core material insertion shaft 41a is driven by the driven gear 41d. The rotation is stopped without any failure.

  Next, the overall operation and action of the winding unit 30 described above will be described, and the configuration will be described in more detail.

  FIG. 3 is an enlarged fragmentary sectional view of the main part of FIG. 1 showing the operation of the winding unit 30.

  In addition, all the operations of the winding unit 30 described in detail below are based on the control signal of the control device 100 (FIG. 1), the disk body driving means, the core support shaft driving means, the sheet adhesion and cutting means, This is done by driving the external shaping roller means and the roll removing means.

    In the initial position shown in FIG. 3, the disk body 32 stops rotating, and at that time, the disk body 32 rotates to the core attachment position A automatically by a core supply means (not shown) or manually by the operator. One cylindrical core member 21 is inserted into the core member insertion shaft 40a of the core member support shaft 40 that is stopped.

  The above-described core material supply means (not shown) can be configured with the same structure as a roll removing means 70 described later.

  Thus, when the cylindrical core material 21 is inserted into the core material insertion shaft 40a, the insertion shaft is inserted by the chucking member 40b of the core material support shaft 40 (see the chucking member 41b in FIG. 2). The core material 21 is fixed to 40a.

  Next, when the fixing of the core material 21 inserted into the insertion shaft 40a is completed, the disc body 32 rotates 90 degrees clockwise from the position shown in FIG. 3, and as shown in FIG. The shaft 40 is brought to the winding position B and stopped there.

  In addition, in the stop position of the disc body 32 shown in FIG. 4, since the subsequent core material support shaft 43 stops at the core material attachment position A, the stopped core material support shaft 43 is shown in FIG. The attachment process of the core material 21 is performed.

  On the other hand, as shown in FIG. 4, when the core material support shaft 40 to which the core material 21 is fixed reaches the winding position B, the leading end 20a of the masking sheet with adhesive tape 20 coming out from the joining rollers 17 and 18 (FIG. 1). Is positioned on the surface of the core material 21.

  When the leading end 20a of the masking sheet with adhesive tape 20 is thus positioned on the surface of the core member 21, the sheet adhesion and cutting means 50 at the standby position descends as shown by the arrow, and the arc as shown in FIG. By the shape part 51, the tip 20 a of the masking sheet 20 with the adhesive tape is pressed and brought into close contact with the surface of the core material 21.

  In this way, when the tip 20a of the masking sheet with adhesive tape 20 comes into close contact with the surface of the core material 21 by the arc-shaped portion 51 of the sheet close-contact and cutting means 50, as shown in FIG. Upward movement is started, and the electromagnetic clutch 40c (see the electromagnetic clutch 41c in FIG. 2) of the core support shaft 40 is turned on while returning to the standby position again. As a result, as shown in FIG. 2) is transmitted to the core material insertion shaft 40a to rotate the core material support shaft 40 for a predetermined time.

  In this way, the electromagnetic clutch 40c of the core support shaft 40 is turned on, whereby the rotational force of the drive motor 49 (FIG. 2) is transmitted to the core insert shaft 40a and rotated for a predetermined time as shown in FIG. To do.

  When the core material insertion shaft 40a rotates for a predetermined time in this way, as shown in FIG. 8, the masking sheet 20 with a predetermined length of the adhesive tape is wound around the core material 21 that is fitted to the core material support shaft 40 to form a cylinder. A masking sheet roll 300 with a pressure-sensitive adhesive tape is formed.

  As shown in FIG. 8, when the masking sheet roll 300 with adhesive tape is formed on the core material insertion shaft 40a at the winding position B, the disk body 32 rotates 90 degrees clockwise again, The material support shaft 40 is stopped at the external shaping position C as shown in FIG.

  As shown in FIG. 9, when the core support shaft 40 reaches the outer shape shaping position C, the sheet contact and cutting means 50 at the standby position starts to descend again as shown by the arrow, and as shown in FIG. The excess masking sheet 20 with adhesive tape attached to the roll 300 of the core support shaft 40 is cut by the cutter portion 52 and the arc-shaped portion 51 is fitted to the next core material support shaft 43. The tip of the masking sheet with adhesive tape 20 is brought into close contact with the surface of the core material 21.

    As shown in FIG. 10, the sheet adhering and cutting means 50 cuts the excess adhesive tape-attached masking sheet 20 attached to the roll 300 of the core material support shaft 40 by the cutter portion 52, and the arc-shaped portion 51. Is pressed against the surface of the core material 21 fitted to the core material support shaft 43 and the tip of the masking sheet 20 with adhesive tape is brought into close contact with the surface of the core material 21, the sheet adhesion and cutting means 50 is as shown in FIG. To move up again and return to the standby position.

    Thus, while the sheet adhesion and cutting unit 50 returns to the standby position, as shown in FIG. 11, the drive motor 61 of the external shaping roller unit 60 is driven and pressed into the circumferential surface of the roll 300. When the shaping roller 62 rotates as shown by an arrow and presses the adhesive tape portion of the masking sheet roll 300 with adhesive tape along the circumferential direction, the adhesive tape in the masking sheet roll 300 with adhesive tape as shown in FIG. A masking sheet roll 300 with an adhesive tape having a very beautiful circumferential surface in which no sagging, warping, elongation, or the like of the part occurs at all will be obtained.

  As shown in FIG. 11, the core material support shaft 43 that has newly reached the winding position B also starts to rotate simultaneously with the driving of the external shaping roller means 60, and as a result, as shown in FIG. The masking sheet 20 with the adhesive tape is wound around the core material 21 fitted to the support shaft 43 to form the masking sheet roll 300 with the adhesive tape.

  Then, as shown in FIG. 12, at the winding position B, the masking sheet 20 with the adhesive tape having a predetermined length is wound around the core support shaft 43 to form the roll 300, and at the outer shape shaping position C, the core is formed. When the shaping of the outer shape of the roll 300 supported by the material bearing shaft 40 is completed, the disk body 32 rotates 90 degrees clockwise again from the position shown in FIG. The core material support shaft 40 that supports the masking sheet roll 300 with the adhesive tape is positioned at the roll removal position D, and the core material support shaft 43 that forms the masking sheet roll 300 with the adhesive tape is now in the outer shape position C. Positioned.

  As shown in FIG. 13, a new core material support shaft 42 that supports the core material 21 is positioned at the winding position B, and a new position relative to the core material support shaft 41 is set at the attachment position A. The core material 21 is fitted.

  As shown in FIG. 13, when the core support shaft 40 that supports the masking sheet roll 300 with the adhesive tape after the external shaping is positioned at the roll removal position D, as shown in FIG. 14, the sheet is in the standby position. The close contact and cutting means 50 starts to descend again, whereby the excess masking sheet 20 with adhesive tape attached to the roll 300 of the core support shaft 43 is cut by the cutter portion 52, and the arc-shaped portion 51 is The tip of the masking sheet 20 with adhesive tape is brought into close contact with the surface of the core material 21 by being brought into pressure contact with the surface of the core material 21 of the core material support shaft 42 positioned at the winding position B.

  As described above, when the tip 20a of the masking sheet with adhesive tape 20 is in close contact with the surface of the core member 21 by the arc-shaped portion 51 of the sheet close-contact and cutting means 50, as shown in FIG. Upward movement is started and the position returns to the standby position again, and the electromagnetic clutch 42c (see FIG. 2 electromagnetic clutch 41c) of the core material support shaft 42 is turned on, thereby reducing the rotational force of the drive motor 49 (FIG. 2). The core material support shaft 42 is rotated for a predetermined time by being transmitted to the material insertion shaft 42a.

  On the other hand, as shown in FIG. 15, when the core material support shaft 40 that supports the masking sheet roll 300 with the adhesive tape after the external shaping is positioned at the roll removal position D, the gripping member 71 of the roll removal means 70 is It moves in the direction of the arrow through one rail travel means 72, and thereafter, the masking sheet roll 300 with adhesive tape after external shaping is gripped between the pair of gripping members 71 (FIG. 2).

  Thus, when the masking sheet roll 300 with adhesive tape is gripped between the pair of gripping members 71, the gripping member 71 is shown in the drawing as shown in FIG. 16 through the second rail running means 73 shown in FIG. The masking sheet roll 300 with an adhesive tape that has been gripped between the pair of gripping members 71 is released, and the masking sheet roll 300 with an adhesive tape that has been finished is dropped downward. While being accommodated in a storage box (not shown) or the like, the roll removing means 70 performs the operation opposite to the above operation and returns to the standby position shown in FIG.

  Thereafter, by repeating the operation from FIG. 8 to FIG. 17 described above, at the winding position B, after completing one masking sheet roll 300 with adhesive tape, by rotating the disc body 32, Since the new core material 21 attached at the core material attachment position A is immediately positioned at the winding position B of the disk body described above, the masking sheet 20 with the adhesive tape is attached to the new core material 21 by a predetermined length. By performing the process of winding up the length of time, the process of continuously forming the masking sheet roll with adhesive tape 300 can be performed, and therefore the production efficiency of the masking sheet roll with adhesive tape can be further improved.

  Finally, the adhesive tape supply unit 200 will be described in detail.

As shown in FIG. 2, in the masking sheet roll manufacturing apparatus 1 with an adhesive tape according to the present invention, an adhesive tape supply unit 200 for supplying the adhesive tape 16 includes a pair of adhesive tape rolls 201 and an adhesive tape arranged horizontally. And a roll 202.

    Among these, one adhesive tape roll 202 is used as a reserve roll.

Next, the operation of the above-described adhesive tape supply unit 200 will be described.
As shown in FIG. 18, the adhesive tape 16 is pulled out from one adhesive tape roll 201 supported by the shaft 203 through tension pulleys 204 and 205, and this is set between the pinch rollers 14 and 15 shown in FIG. . In this state, the masking sheet roll manufacturing apparatus 1 with adhesive tape is operated, and the masking sheet roll 300 with adhesive tape is continuously produced as described above.

  On the other hand, when the pressure-sensitive adhesive tape 16 is removed from one pressure-sensitive adhesive tape roll 201, the pressure-sensitive adhesive tape 16 is immediately removed from the preliminary pressure-sensitive adhesive tape roll 202 supported by the shaft 206 as shown in FIG. , 205, and is set between the pinch rollers 14 and 15 shown in FIG. A new adhesive tape roll 208 is set on the vacant shaft 203 to prepare for the next replenishment of the adhesive tape.

  According to the adhesive tape supply unit 200 of the present invention described above, since one spare adhesive tape roll is always provided, when the adhesive tape 16 is out of supply, a new adhesive tape roll can be immediately supplied. For this reason, it is possible to further improve the production efficiency of the masking sheet roll 300 with the adhesive tape by reducing the time for supplying the adhesive tape as much as possible.

  Moreover, since the adhesive tape roll is arranged horizontally, the height in the vertical direction of the masking sheet roll manufacturing apparatus 1 with adhesive tape is low, and the apparatus can be made compact.

    As described above, the present invention continuously wraps a masking sheet with an adhesive tape around different core materials without extracting the core material, thereby further improving the production efficiency of the masking sheet roll with an adhesive tape. It is suitable for a masking sheet roll manufacturing apparatus with an adhesive tape.
