Description

TECHNICAL FIELD [0001] The present invention relates to a scraping device for pulling a continuous label sheet, and a method for winding a scraping scraper.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pulling scrap winding device and a pulling scraper winding method of continuous label paper.

This application claims priority to Japanese Patent Application No. 2017-154396, filed on August 9, 2017, the contents of which are incorporated herein by reference.

An apparatus for pulling a scrabble on a continuous label sheet, comprising: a device for printing a character or a figure on a continuous label sheet, punching the label base and the adhesive layer of the continuous label sheet in a predetermined shape and peeling off unnecessary punched scrap from the mount And winding the scrap on the scrap-up shaft. It is difficult to secure the strength of the punched scrap with the label base and adhesive layer of the predetermined shape peeled off, and there is a possibility that the punched scrap is cut off until reaching the scrap-up reel shaft.

Therefore, it is not preferable to apply a strong tensile force to the scraping scraper until the scraping scraper is peeled off from the ground and reaches the scraping-up shaft.

Here, the tension applied to the scraping scraper fluctuates with the change in the roll diameter of the scraping wound around the scraping-up shaft if the torque of the scraping-up shaft is constant. In addition, the tension applied to the scraping scraper affects the torque fluctuation of the servomotor due to the mechanical loss of the mechanical system and the acceleration of the winding speed. Therefore, there is a possibility that the pulling scrap is cut off due to the tension fluctuation during pulling of the pulling scrap.

In addition, the stamp scrap is punched out in a predetermined shape. Therefore, the punch scrap has a property of shrinking in the direction perpendicular to the direction of the tensile force (width direction of the punch scrap) when a tensile force is applied in the conveying direction. Here, when the predetermined shape is a circular or irregular shape other than a rectangular shape, the shrinkage amount of the punch scrap is hard to be constant. For this reason, it is conceivable that the load is concentrated on the portion where the shrinkage amount of the punch scrap is large, and the punch scatters in a direction perpendicular to the direction of the tensile force. In this state, when the tension of the scraping scraper fluctuates, the scraping scraper is easily broken.

Particularly, if a section (hereinafter, referred to as a scrap path) from the peeling of the punch to the scraping-up shaft is long, the amount of shrinkage in the width direction of the punch scrap becomes large and the portion where the load is concentrated increases. Further, when the shrinkage amount in the width direction of the punch scrap is large, a large portion and a small portion are formed in the roll diameter of the wound punch scrap, and the punch scrap that is wound in a portion having a large roll diameter becomes high tension.

The punch scrap has a large shrinkage amount in the width direction of the punch scrap, so that it is likely to be cut at a portion where the load is concentrated or at a portion where the scrap coiling diameter is high and becomes high tension.

In order to suppress the cutting of the punching scrap, there is a device for pushing the outer periphery of the punching scrach wound around the scrapping punching shaft against the scraping roll driving roller. The scraping roll driving roller rotates synchronously at the conveying speed of the continuous label paper.

And the adhesive layer of the punch scrap is attached to the scrap-up shaft by pressing the outer periphery of the punch scrap against the scrap roll driving roller. In this state, the scraping-up shaft is driven to rotate, and the scraping scraper is continuously wound in the form of a roll. According to the pulling scraping device of the continuous label paper, the pulling scrap can be wound without being given tension, and it is possible to suppress cutting of the pulling scrap (see, for example, Patent Document 1).

Japanese Patent Application Laid-Open No. 2000-355459

However, when the punched area of the continuous label paper (that is, the area of the predetermined shape) is large, the shape of the outer peripheral surface of the punched scrap wrapped around the scrap-up take-up shaft is distorted. Therefore, according to the pulling scraping device of the continuous label paper of Patent Document 1, the outer circumferential surface of the scraping scraper is in press contact with the scraping roll driving roller in a distorted state. Therefore, there is a possibility that vibration occurs in the scrap.

Here, in general, when the punched area of the continuous label paper is large, the area of the punched scrap is reduced. As a result, the punch scrap is easily broken by vibration, which hinders the punching speed of the punch scrap.

Accordingly, the present invention provides a pulling scraper winding device and a pulling scrape winding method of continuous label paper capable of suppressing cutting of the punch scrap and speeding up the punch scrap.

In order to solve the above problems, an apparatus for pulling a scraping scraper of a continuous label sheet, which is an aspect of the present invention, comprises a peeling roller for conveying a continuous label sheet subjected to half stamping and separating the stamped product, A scraping up shaft disposed to be spaced apart from the peeling roller for winding the scraping scrap in the form of a roll; and a movable scraping mechanism for moving the scraping off shaft in a direction A first detection section which is provided in the conveying path of the continuous label paper and which detects the conveyance amount of the continuous label sheet; a second detection section which detects one revolution of the scrap takeup shaft; And a second detection unit for detecting an amount of the phase difference between the first detection unit and the second detection unit, Having a computing unit to obtain the roll diameter of the punching scrap, and based on the roll diameter calculated from the operating section, and controls to move the take-up shaft in the direction in which the scrap away from the separation roller.

Further, in the apparatus for pulling the scraping scrap of continuous label paper which is one aspect of the present invention, it may further comprise a tension adjusting unit provided on a driving shaft of the scraping-up shaft and adjusting a tension applied to the scraping scraper.

Further, in the apparatus for pulling the scraping scrap of continuous label paper which is one aspect of the present invention, a touch roller capable of coming into contact with the outer circumferential surface of the pulling scrach wound around the scraping-off shaft is provided so as to correspond to the change in the roll diameter .

A method of winding a scraping scraper of continuous label paper, which is an aspect of the present invention, is a method of winding a continuous label paper subjected to half-cut processing and separating the continuous label paper into a punching product adhered to the paper with a peeling roller and a punching scrap A scraping step of scraping the scraped scraper peeled off from the ground on the scraping-up shaft; a roll diameter calculating step of calculating a roll diameter of the scraping wound on the scraping-up shaft; And a scraping-up shaft moving step of moving the scraping-up shaft in a direction away from the peeling roller when the roll diameter is larger than a predetermined rising start roll diameter.

According to the pulling scraping device for continuous label paper of the present invention, it is possible to move the scraping-up shaft in a direction away from the peeling roller, based on the roll diameter of the scraping scrach wound around the scraping-up shaft. Therefore, the interval between the outer circumferential surface of the scraping scrach wound around the scraping-up shaft and the outer circumferential surface of the peeling roller can be suppressed to be small (the gap also includes zero). That is, the scrap path dimension from the outer circumferential surface of the peeling roller to the outer circumferential surface of the scraping scraper can be suppressed to be small.

Therefore, even when the predetermined shape of the punch product is a circular or irregular shape other than a rectangular shape, the tension generated in the punch scrap during winding can be stabilized, thereby preventing the punch scrap from being cut to the utmost.

Further, by suppressing the scrap path dimension from the outer circumferential surface of the peeling roller to the outer circumferential surface of the scraping scraper to be small, it is possible to suppress the scraping of the scraping scraper even when a strong tension is applied to the scraping scraper as compared with the prior art.

Furthermore, by suppressing the cutting of the scraping scrap, the speed at which the scraping scrape is wound on the scraping-off shaft can be accelerated. As a result, the printing speed of the continuous label paper can be increased, and the productivity of the punching product can be greatly improved.

Further, by providing the tension adjusting portion on the driving shaft of the scraping-up shaft, the tension applied to the scraping scraper by the winding can be adjusted and kept constant. As a result, the breaking scrape is prevented from being cut off due to the tension fluctuation at the time of winding, and the breaking scrap can be wound in a stable state.

Further, the touch roller is made to correspond to the change of the roll diameter, so that the touch roller can come into contact with the outer peripheral surface of the scraping scrap. Therefore, the entire outer circumferential surface of the scraping scrap can be evenly flattened by the touch roller. As a result, it is possible to more preferably maintain the distance between the outer circumferential surface of the scraping scrach wound around the scraping-up shaft and the outer circumferential surface of the peeling roller. Therefore, it is possible to stabilize the tension generated in the scraping scrape during winding more satisfactorily.

According to the method of winding the scraping scraper of the continuous label paper according to the present invention, in the scraping step, the scraping scrape is wound around the scraping-up shaft and the roll diameter of the scraping scrape is obtained in the roll diameter calculating step. Further, in the scraping-up shaft moving step, when the roll diameter obtained by the roll diameter calculating step is larger than a preset rising start roll diameter, the scraping-off shaft is moved in a direction away from the peeling roller.

Therefore, the interval between the outer circumferential surface of the scraping scrach wound around the scraping-up shaft and the outer circumferential surface of the peeling roller can be suppressed to be small (the gap also includes zero). In other words, the scrap path dimension from the outer circumferential surface of the peeling roller to the outer circumferential surface of the scraping scraper can be suppressed to be small.

Therefore, even when the predetermined shape of the punch product is a circular or irregular shape other than a rectangular shape, the tension generated in the punch scrap during winding can be stabilized, thereby preventing the punch scrap from being cut to the utmost.

Further, by suppressing the scrap path dimension from the outer circumferential surface of the peeling roller to the outer circumferential surface of the scraping scraper to be small, it is possible to suppress the scraping of the scraping scraper even if a strong tension is applied to the scraping scraper as compared with the prior art.

Furthermore, by suppressing the cutting of the scraping scrap, the speed at which the scraping scrape is wound on the scraping-off shaft can be accelerated. As a result, the printing speed of the continuous label paper can be increased, and the productivity of the punching product can be greatly improved.

[ Hereinafter, the pulling scraping device 10 for continuous label paper will be abbreviated as " punching scraping device 10 ".

As shown in Figs. 2 and 3, the continuous label sheet 30 is conveyed in the direction indicated by the arrow A in the punch scraping device 10. The continuous label sheet 30 is formed by adhering the label base material 32 to the ground 31 through an adhesive layer (not shown). A printing process is performed in which letters or figures are printed on the label base material 32 of the continuous label sheet 30 on the upstream side in the conveying direction of the take-up scraping-up device 10 or in a printing unit provided in another line device All.

(Hereinafter, referred to as a label) 34 on the label base material 32 and the adhesive layer by means of a sculpting knife or a knife (or a flexible die) or a laser beam in the processing step after the printing process, Processing is performed. In the half punching process, the label base material 32 and the adhesive layer of the continuous label paper 30 are processed so as to cover the frame in a predetermined shape, and the paper material 31 is not processed.

After the label 34 is subjected to the half-cut processing of the continuous label sheet 30, the release scraper 36 is peeled from the base 31 of the continuous label sheet 30 by the fixed peeling roller (peeling roller) Is peeled off. That is, the label base material 32 of the continuous label paper 30 is fixed by the fixed peeling roller 47 to the label 34 adhering to the paper 31 and the punching scrap 36 peeled off from the paper 31 Separated. The label 34 adhered to the paper 31 is conveyed in the direction indicated by the arrow B. On the other hand, the punching scrap 36 separated from the paper 31 is attached to the paper tube 64 of the scraping-up shaft 51 and wound in the form of a roll by the rotation of the scrap-up shaft 51.

Hereinafter, the punch scrap 36 wound in a roll form on the scrap punch shaft 51 is referred to as " punch scrap roll 37 ".

Hereinafter, the structure of the take-up scraop winding device 10 will be described with reference to Figs. 1 to 10. Fig.

1 and 5, a winding mechanism 14, a vertical movement mechanism 16, a touch roller mechanism 18, and a detection means 20 are provided on the frame 12 of the pulling scraping device 10, . A conveying roller 41, a nip roller (or nip roller) 42, and guide rollers 43 to 45 are rotatably supported on the frame 12. The conveying roller 41 conveys the continuous label sheet 30 with the nip roller (or nip roller) 42 therebetween.

The conveying roller 41, the nip roller (or nip roller) 42 and the guide rollers 43 to 45 are provided in order from the upstream side of the conveying path of the continuous label sheet 30, for example, (30).

Further, a fixed separation roller 47 is rotatably supported on the frame 12. In addition, an escape hole 48 is formed in the frame 12. The escape hole 48 extends vertically so that the scrap-up shaft 51 can move in the vertical direction.

The winding mechanism 14 includes a scraping-up shaft 51, a powder clutch (tension adjusting portion) 53, and a first servo motor 55. The scrap-up shaft 51, the powder clutch 53 and the first servo motor 55 are attached to the moving body 76 of the up-and-down moving mechanism 16.

The scrap-up shaft 51 is rotatably supported on the upper portion 85a of the first table 85 of the moving body 76 through a bearing water. The scraper take-up shaft 51 is provided on the upper side in the vertical direction with respect to the roller center 47b of the fixed type peeling roller 47. [

Further, the scrap-up shaft 51 is formed in a hollow shape having a circular section. A plurality of elongated holes (slits) 57 extending in the axial direction are formed on the outer periphery of the scrap-up shaft 51. A first timing pulley 58 is attached to the scraper take-up shaft 51 on the same axis.

A rubber tube is accommodated in the scrap-up shaft 51 so as to be elastically deformable. A metal hook (hereinafter, referred to as a lug) 62 is provided on the outer periphery of the rubber tube. An air passage is communicated inside the rubber tube. The air flow path communicates with the air supply source through the rotary joint 63.

The air supplied from the air supply source is charged into the rubber tube through the rotary joint 63 or the air passage. As a result, the rubber tube expands outward in the radial direction, and the lug 62 protrudes radially outward from the elongated hole 57 of the scraping-up shaft 51. Here, a branch pipe 64 (see Fig. 2) is engaged with the scrap-up shaft 51. [ Therefore, the lug 62 protruding from the elongated hole 57 of the scraping-up shaft 51 comes into contact with the inner surface of the paper tube 64, and the paper tube 64 is fixed on the scraper-up shaft 51 on the same axis .

In the present embodiment, an example of projecting the lug 62 outward in the radial direction by using air pressure is described, but the present invention is not limited thereto. As another example, for example, the lug 62 may be protruded mechanically outward in the radial direction.

A rotation stopping bracket 65 is attached to the case of the rotary joint 63.

The rotation stopping bracket 65 is attached to the second table 86 of the moving body 76. Therefore, the accompanying rotation of the case of the rotary joint 63 is restrained by the rotation stopping bracket 65. [

As shown in Figs. 4 to 6, a first servo motor 55 is connected to the scrap-up shaft 51 via a powder clutch 53. As shown in Fig. The first servo motor 55 is attached to the plate 83 under the second table 86. The plate 83 is attached to the lower portion of the second table 86.

Specifically, a plurality of first long holes 86a are formed in the lower portion of the second table 86 so as to extend in the vertical direction. The plate 83 is attached to the lower portion of the second table 86 by the first bolt 81 passing through the plurality of first long holes 86a. The first servomotor 55 is attached to the lower portion of the second table 86 of the moving body 76 through a plate 83.

Therefore, the first servo motor 55 can be moved in the vertical direction by loosening the first bolt 81 and moving the plate 83 in the vertical direction. That is, the first servo motor 55 can adjust the position of the powder clutch 53 in the vertical direction.

A second timing pulley 66 is attached to the output shaft of the first servo motor 55 on the same axis.

In the second table 86, a powder clutch 53 is disposed between the first servo motor 55 and the scrap up / Here, a plurality of second long holes 86b are formed on the second table 86 so as to extend in the vertical direction. The second bolt 97 is configured to penetrate a plurality of second elongated holes 86b and to be screwable with respect to the pair of connecting members 87. [ And the second table 86 can be fixed by tightening the second bolt 97.

Therefore, the powder clutch 53 can be moved up and down by moving the second table 86 up and down by loosening the second bolt 97. [ That is, the powder clutch 53 can be adjusted in the vertical direction with respect to the scraping-up shaft 51.

The powder clutch 53 is installed on the drive shaft of the scraping-up shaft 51. The powder clutch 53 is generally used for production of long films, for example. The powder clutch 53 uses powder (magnetic iron) for transmitting the torque, and combines the smoothness of the fluid clutch and the high-efficiency connection of the friction disk type clutch.

That is, by smoothly sliding the powder clutch 53, it is possible to keep the variation of the tension imparted to the punch scrap 36 constant. Further, the set torque of the powder clutch 53 can be changed stepwise according to the roll diameter D (see Fig. 2) of the scraping roll 37. [ Therefore, by providing the powder clutch 53 on the driving shaft of the scraping-up shaft 51, the tension applied to the scraping scraper 36 of the scraping scraper roll 37 can be adjusted to keep the variation of the tension constant.

As a result, the breaking scraper 36 can be prevented from being cut off due to a variation in the tension applied to the scraping scraper 36.

2 and 3, in the present embodiment, the number of revolutions of the scraping-up shaft 51 is set such that when the roll diameter D of the scraping roll 37 is minimum (that is, 64), the winding amount of the scraping scraper 36 is set to be at least a constant value that is equal to or larger than the conveying amount of the continuous label sheet 30 in the conveying path.

Therefore, the punch scrap 36 is wound around the scraping-up shaft 51 constantly. On the other hand, when the roll diameter D of the punching scrap roll 37 is increased, the amount of punching scrap 36 of the scrapping punching shaft 51 increases with respect to the conveying amount of the continuous label sheet 30 in the conveying path. In this case, the tension applied to the punch scrap 36 increases, so that the set torque of the powder clutch 53 (see Fig. 6) is adjusted stepwise.

As shown in Figs. 2 and 5, the pulling scrap 36 of the punch scraping roll 37 is given a tensile force.

The tension is affected by a change in the roll diameter D of the punch scraper roll 37 or a mechanical loss of the mechanical system or a torque fluctuation at the time of acceleration / deceleration of the first servo motor 55 and fluctuates. Therefore, by interposing the powder clutch 53 between the scraping-up shaft 51 and the first servo motor 55, the variation of the tension applied to the scraping scraper 36 can be kept constant.

The powder clutch 53 also has a structure capable of stepwise changing the set torque in accordance with the roll diameter D of the punch scraping roll 37 in order to correspond to the fluctuation of the roll diameter D of the punch scraping roll 37. [ That is, the tension imparted to the punch scrap 36 fluctuates in accordance with the change in the roll diameter D of the punch scrap roll 37 when the torque of the scrap retracting shaft 51 is constant. Therefore, by changing the set torque of the powder clutch 53 stepwise according to the roll diameter D of the scraping roll 37, the fluctuation of the tension can be kept constant.

Thus, by providing the powder clutch 53 on the driving shaft of the scraping-up shaft 51, the tension applied to the scraping scraper 36 by the winding can be kept constant. Thereby, it is possible to suppress the breaking of the punching scrap 36 due to the tension fluctuation at the time of punching and to wind the punching scrap 36 in a stable state.

The set torque of the powder clutch 53 can be changed on the monitor screen provided in the pulling scraper winding device 10. [

The powder clutch 53 is attached to the upper portion of the second table 86 of the moving body 76. A third timing pulley 68 is attached to the input shaft of the powder clutch 53 in a coaxial manner. A fourth timing pulley 69 is attached to the output shaft of the powder clutch 53 in a coaxial manner. The third timing pulley 68 is connected to the fourth timing pulley 69 via the input shaft and the output shaft of the powder clutch 53.

The second timing pulley 66 of the first servo motor 55 is connected to the third timing pulley 68 of the powder clutch 53 via the first timing belt 71. [ The tension is preferably adjusted by moving the first servo motor 55 in the up and down direction by loosening the first bolts 81 (see Fig. 4) of the first timing belt 71.

The fourth timing pulley 69 of the powder clutch 53 is connected to the first timing pulley 58 of the scraping-up shaft 51 via the second timing belt 72. The tension is preferably adjusted by releasing the second bolts 97 (see FIG. 4) and moving the powder clutch 53 in the vertical direction.

In this state, the second timing pulley 66 is rotated by the first servo motor 55 so that the rotation of the second timing pulley is transmitted to the third timing pulley 53 of the powder clutch 53 via the first timing belt 71, (68). As the third timing pulley 68 rotates, the input shaft of the powder clutch 53 rotates.

As the input shaft of the powder clutch 53 rotates, the output shaft of the powder clutch 53 rotates. As the output shaft of the powder clutch 53 rotates, the fourth timing pulley 69 rotates. The rotation of the fourth timing pulley 69 is transmitted to the first timing pulley 58 through the second timing belt 72. [ As the first timing pulley 58 rotates, the scrabb retracting shaft 51 rotates in the retracting direction of the scraping scraper 36. As a result, the punching scrap 36 is wound on the paper tube 64 of the scrap-up shaft 51. [

Here, the fourth timing pulley 69 and the first timing pulley 58 are formed with the same number of teeth. Therefore, the number of rotations of the scraping-up shaft 51 becomes equal to the number of rotations of the output shaft of the powder clutch 53. The second timing pulley 66 of the output shaft of the first servo motor 55 and the third timing pulley 68 of the input shaft of the powder clutch 53 are connected to the fourth timing pulley 69).

As described above, by interposing the powder clutch 53 between the scraping-up shaft 51 and the first servo motor 55, it is possible to keep the fluctuation of the tension imparted to the scraping scraper 36 constant by the powder clutch 53 have.

The tension applied to the scraping scraper 36 fluctuates in accordance with the change in the roll diameter D of the scraping roll 37 when the torque of the scraping-off shaft 51 is kept constant. The setting torque of the powder clutch 53 can be changed stepwise according to the roll diameter D of the punch scraping roll 37 in order to cope with the fluctuation of the roll diameter D. [

Thereby, it is possible to prevent the breaking scrap 36 from being cut off due to the variation of the tension applied to the breaking scrap 36. [

The connection of the first servo motor 55, the powder clutch 53, and the scrap-up shaft 51 is not limited to the configuration of the present embodiment. The scrap-up shaft 51 and the first servo motor 55 may be connected through the powder clutch 53.

Therefore, the plurality of sliders 84, the first table 85, the connecting member 87, and the second table 86 are supported by the pair of linear guides 75 so as to be movable up and down. A winding mechanism 14 is attached to the first table 85 and the second table 86. That is, the winding mechanism 14 is supported on the pair of linear guides 75 via the moving body 76 so as to be movable in the vertical direction. A pair of ball screws 77 are provided on both sides of the moving body 76.

The pair of ball screws 77 are provided on the frame 12 at both sides of the moving body 76 and at a position spaced apart from the escape hole 48 from a pair of the linear guides 75 And the rotation is freely attached. A pair of ball screws (77) extend in the vertical direction along the escape hole (48). A nut (not shown) is rotatably supported by a pair of ball screws 77, and a nut is supported by the connection bracket 92. The connecting bracket 92 is attached to the connecting member 87 (see Fig. 4).

A pair of driven gears 78 are attached to the lower ends of the pair of ball screws 77. Concretely, one of the pair of driven gears 78 is attached to one side of the pair of ball screws 77 on the same axis. Further, the other of the pair of driven gears 78 is attached to the other side of the pair of ball screws 77 on the same axis. The pair of driven gears 78 is a bevel gear.

A pair of driven gears (78) are engaged with a pair of driving gears (79). That is, one of the pair of driven gears 79 is engaged with one of the pair of driven gears 78. Further, the other side of the pair of driven gears 79 is engaged with the other side of the pair of driven gears 78.

The pair of drive gears 79 are bevel gears and are mounted on the same axis in the vicinity of both ends of the rotating shaft 89. [ Both ends of the rotary shaft 89 are rotatably supported on the frame 12 through a shaft 91. A fifth timing pulley 93 is attached to the center of the rotary shaft 89 on the same axis.

The tension of the third timing belt 96 is adjusted preferably by moving the second servomotor 82 in the vertical direction.

The sixth timing pulley 95 is rotated by the second servo motor 82 so that the rotation of the sixth timing pulley is transmitted through the third timing belt 96 to the fifth timing pulley 93). As the fifth timing pulley 93 rotates, the pair of driving gears 79 rotate through the rotating shaft 89. [

As the pair of drive gears 79 rotate, the pair of driven gears 78 rotate.

A winding mechanism 14 is attached to the first table 85 and the second table 86 of the moving body 76. As the moving body 76 moves in the vertical direction, the scraping up shaft 51 of the winding mechanism 14 moves in the vertical direction.

As shown in Figs. 5 and 7, the scraping up shaft 51 is moved up and down (in the direction of the arrow C) by the up-and-down moving mechanism 16 to cope with a change in the roll diameter D of the scraping roll 37 So that the scrap-up shaft 51 can be moved up and down. That is, the scraping-up shaft 51 can be moved by the up-and-down moving mechanism 16 in the direction away from the stationary peeling roller 47 or in the direction close to the stationary peeling roller 47.

Thereby, the outer peripheral surface 36a of the scraping scraping roll 37 and the outer peripheral surface 47a of the fixed type separating roller 47 are close to each other or the outer peripheral surface 36a of the scraping roll 37 is separated from the outer peripheral surface 47a of the non- Up shaft 51 at a so-called kiss-touch position where the outer circumferential surface 47a of the roller 47 comes into slight contact.

A touch roller mechanism 18 (see Fig. 6) is provided above the up-and-down moving mechanism 16 and the winding mechanism 14. [

8 and 9, the touch roller mechanism 18 includes a rotary actuator 101, an arm 102, a touch roller 103, and a load block 104. 9, for the sake of easy understanding of the configuration of the touch roller mechanism 18, the touch roller 103 is shown in a state in which it is disposed upward.

The rotary actuator 101 is attached to the upper end portion 12a of the frame 12 through a support bracket 106. [ A central portion of the arm 102 (hereinafter referred to as an arm center portion) 102a is attached to the rotation support shaft 107 of the rotary actuator 101. [

Therefore, the arm 102 is urged in the direction of the arrow E by the urging force of the rotary actuator 101. [ A touch roller 103 is attached to one end 102b of the arm 102. [

That is, the touch roller mechanism 18 is a swinging touch roller attached to the rotation support shaft 107 of the rotary actuator 101.

The touch roller 103 has a roller shaft 108 attached to one end portion 102b of the arm 102 and a roller body 112 supported on the roller shaft 108. The roller shaft 108 has a roller shaft 108, The roller shaft 108 has a proximal end 108a attached to one end 102b of the arm 102. [ The roller shaft 108 extends in a direction intersecting (specifically orthogonal) with respect to the arm 102. The roller body 112 is attached to the roller shaft 108 on a coaxial and rotatable manner via a bearing 109.

And a load block 104 is attached to the other end portion 102c of the arm 102. [ The load block 104 is movably supported along the arm 102 by unscrewing the adjustment bolt 114. [ Therefore, the mounting position of the load block 104 can be adjusted.

The load block 104 is attached to the other end portion 102c of the arm 102 so that the balance with the pressing force of the rotary actuator 101 is maintained. Therefore, it is possible to preferably adjust the contact force of the scraping roll 37 with the outer peripheral surface 36a by the touch roller 103 (i.e., the roller body 112).

Further, the arm 102 is supported so as to be pivotable about the rotation support shaft 107. Therefore, the touch roller 103 can be moved in correspondence with the roll diameter D of the scraping roll 37. [ That is, the outer peripheral surface 36a of the punch scrap roll 37 can be brought into contact with the roll diameter D of the punch scrap roll 37.

The rotary support shaft 107 of the rotary actuator 101 is rotated so that the touch roller 103 can be pivoted up to the pivot angle of the arm 102 when the roll diameter D of the punch scrap roll 37 reaches the maximum diameter. Is set.

The touch roller 103 is capable of adjusting the air pressure by a regulator provided in the air piping path. For example, by adjusting the air pressure of the regulator to 0.0 to 0.1 MPa, the contact pressure of the touch roller 103 is made to correspond to the conditions such as the type of the continuous label sheet 30 (see Fig. 3) And can be arbitrarily changed.

That is, the touch roller 103 is adjusted so as to contact with the outer circumferential surface 36a of the scraping roll 37 with a slight pressure so as not to generate vibration. A slight pressure is applied to the outer circumferential surface 36a of the punch scraping roll 37 so as to prevent the occurrence of the vibration so that the pulling scraper 36 is wound around the scraping- ) It is possible to prevent air from being excessively entrained between the layers. That is, the roll shape of the scraping roll 37 can be desirably corrected by the touch roller 103.

The irregularities of the outer circumferential surface 36a of the scraping roll 37 can be uniformed to some extent by correcting (correcting) the roll shape of the scraping scraping roll 37 with the touch roller 103. [ Thus, the fluctuation of the tension caused by the irregularities of the outer circumferential surface 36a of the scraping roll 37 can be suppressed to some extent.

Further, the irregularities of the outer circumferential surface 36a of the scraping roll 37 are made uniform. Thus, even when the outer circumferential surface 36a of the scraping scraping roll 37 and the outer circumferential surface 47a of the stationary peeling roller 47 are in contact with each other, the unevenness of the outer circumferential surface 36a of the scraping scraping roll 37 and the unevenness of the stationary peeling roller 47 It is possible to prevent the outer circumferential surface 47a of the outer circumferential surface 47a from coming into pressure contact with vibration.

The touch roller 103 is made to correspond to the change in the roll diameter D of the punch scrap roll 37 so that the touch roller 103 can come into contact with the outer peripheral surface 36a of the punch scrap roll 37. [ Therefore, the entire outer circumferential surface 36a of the scraping roll 37 can be flattened uniformly by the touch roller 103. [ The distance r between the outer circumferential surface 36a of the scraping roll 37 and the outer circumferential surface 47a of the stationary peeling roller 47 can be preferably maintained. Therefore, the tension generated in the scraping scraper 36 being wound on the scraping-up shaft 51 can be stabilized well.

When the touch roller 103 is not used, a swivel fixing part 105 for fixing the touch roller 103 to the frame 12 is provided. The swivel fixing portion 105 has a fixing pin 123 and a chain 124. [ And the fixing pin 123 is connected to the frame 12 through the chain 124. [ An attachment hole 102d is formed on the side of the one end 102b of the arm 102. [ When the touch roller 103 is not used, the fixing pin 123 is fitted into the mounting hole 102d. The chain 124 is pulled and can be fixed to the frame 12 so as not to pivot the touch roller 103 against the pressing force of the rotary actuator 101. [

In the present embodiment, the rotary actuator 101 is used as the pivot means of the arm 102, but the present invention is not limited thereto. As another example, a rubber damper or the like may be used.

4 and 6, the detecting means 20 includes a first sensor 116, a second sensor 117, a third sensor (second detecting portion 118), a line encoder , 119 (see Fig. 8).

The first sensor 116 is attached to the upper portion 12b of the frame 12 through a first attaching bracket 127. [ The first sensor 116 detects the detection piece 128. The detection piece 128 is attached to an end portion 85c of the side surface 85b of the first table 85. The first sensor 116 detects the detection piece 128 to determine the upper limit of the first table 85 (that is, the moving body 76) moving in the vertical direction.

The second sensor 117 is attached to a portion 12c near the lower portion of the upper portion 12b of the frame 12 through the second bracket 129. [ The second sensor 117 detects the detection piece 128. The second sensor 117 detects the detection piece 128 to determine the lower limit of the first table 85 (that is, the moving body 76) moving in the vertical direction.

Here, the attachment position and the detection position of the first sensor 116, the second sensor 117, and the number of the first sensor 116 and the second sensor 117 are not limited to the embodiments. For example, the first sensor 116 and the second sensor 117 may be attached to the front side of the first table 85. Further, a long hole may be formed in the front face of the slider 84 with a length of the maximum movement amount + alpha, and one sensor may be provided on the front face side of the slider 84. [ Further, the side surface 85b of the first table 85 may be peeled off in steps in the up and down direction, and the convexity may be determined as the amount of movement + alpha, which is set at one place.

The third sensor 118 is attached to the output shaft side bracket 121 of the powder clutch 53. Specifically, the plate 122 is attached to the output shaft side of the powder clutch 53. One end (121a) of the bracket (121) is attached to the lower end of the plate (122). And the third sensor 118 is attached to the other end 121b of the bracket 121. [

A rotating body 132 is provided on the same axis as the fourth timing pulley 69 of the output shaft of the powder clutch 53 and a detecting piece 133 is provided on the outer periphery of the rotating body 132.

Here, the fourth timing pulley 69 of the output shaft of the powder clutch 53 and the first timing pulley 58 of the scrap-up shaft 51 are formed with the same number of teeth. That is, the number of revolutions of the rotating body 132 (i.e., the detecting piece 133) becomes equal to the number of revolutions of the scraping-up shaft 51. Therefore, by detecting the detection piece 133 by the third sensor 118, one rotation of the scraping-up shaft 51 is detected.

Hereinafter, a pulse signal representing the number of revolutions of the scraping-up shaft 51 is referred to as a " winding pulse ".

Here, the attachment position of the third sensor 118 and the detection piece 133 is not limited to the example of this embodiment. The third sensor 118 and the detecting piece 133 may be attached to the rotation position of the scraping-up shaft 51 at the same position as the frame 12, for example. The third sensor 118 and the detection piece 133 need only be attached at the same position as the one pulse is emitted from the third sensor 118 every time the scraping-up shaft 51 makes one revolution.

1 and 10, the conveying path of the continuous label sheet 30 is provided with a third servomotor (not shown) for conveying the continuous label sheet 30, (Or Nipkoro) 42, and guide rollers 43 to 45 are provided. And a line encoder 119 is provided in addition to the third servo motor.

The line encoder 119 is a rotary encoder connected to the conveying path of the continuous label sheet 30 (specifically, the conveying roller 41). The line encoder 119 transmits a pulse signal corresponding to the amount of conveyance of the continuous label sheet 30. That is, the line encoder 119 detects the amount of conveyance of the continuous label sheet 30. Hereinafter, the pulse signal corresponding to the carry amount is referred to as a " carry pulse ".

By detecting the conveying pulse of the line encoder 119 with respect to the winding pulse when the scraping-up shaft 51 makes one revolution, it is possible to detect the roll diameter of the scraping roll 37 from the conveying amount of the continuous labeling paper 30 D can be obtained by an operation.

The positions of the conveying roller 41, the nip roller (or nip roller) 42, the guide rollers 43 to 45, and the line encoder 119 are not limited to the positions in the drawing.

The roll diameter D of the scraping roll 37 is calculated by the calculating unit 22 based on the winding pulse and the conveying pulse amount. That is, the arithmetic operation unit 22 calculates the number of revolutions of the take-up scraper roll 37 from the amount of conveying pulses of the line encoder 119 for the take-up pulses emitted from the third sensor 118 each time the scraping- The roll diameter D can be obtained.

Next, a method of obtaining the roll diameter D of the punch scraping roll 37 with the calculating unit 22 will be described with reference to Fig.

10, the roll diameter of the take-up scraper roll 37 is D, the feed amount of the continuous label sheet 30 when the scraper take-up shaft 51 makes one revolution (that is, Is L, the following is obtained.

D = L /? (1)

On the other hand, the first conveying roller 41 and the line encoder 119 of the roll diameter d are provided in the conveying path of the continuous label sheet 30. [

For one rotation of the first conveying roller 41, the number of conveying pulses transmitted by the line encoder 119 is n. When the continuous label sheet 30 has been conveyed by the distance pi, the n lines of the conveying pulses are emitted from the line encoder 119. [ Therefore, the feed amount of the continuous label sheet 30 per one conveying pulse transmitted from the line encoder 119 becomes? D / n.

Here, when the number of transmission pulses of the conveyance pulse of the line encoder 119 at the time of one rotation of the scraping-up shaft 51 is N,

L =? DN / n (2)

.

By substituting the equation (2) into the equation (1)

D = dN / n (3)

Can be obtained.

The roll diameter d and the number n of conveying pulses of the line encoder 119 are known values. Therefore, the roll diameter D of the scraping roll 37 can be obtained from the number N of conveying pulses transmitted from the line encoder 119.

Next, an example of raising the scraping-up shaft 51 to the control unit 24 will be described with reference to Figs. 3, 11, and 12. Fig.

As shown in Fig. 3, the peeled punching scrap 36 is in a state of being punched out of the label 34. Therefore, when the tension applied to the scraping scraper 36 varies during the scrap-up operation to the scraping-up shaft 51, the scraper is likely to be cut. Here, the label 34 is not limited to a single tetragon. Particularly, when the predetermined shape of the label 34 is a circular or irregular shape other than a rectangular shape, if the tension of the punch scrap 36 varies, the punch scrap 36 tends to be cut. 3, the label 34 will be described as a rectangle for convenience in order to facilitate understanding of the configuration.

For example, when the scrap path is long, the punching scrap 36 of the label 34 has a large amount of shrinkage in the width direction of the punching scraper 36, It becomes easy to cut at a position where the tension applied to the enlarged scraper 36 is increased.

Here, the scrap pass refers to a section from when the scraping scraper 36 is peeled off from the ground 31 to reach the scraper take-up shaft 51.

On the other hand, it is conceivable that the outer circumferential surface 36a of the scraping roll 37 is held in pressure contact with the outer circumferential surface 47a of the stationary peeling roller 47. In this state, a difference in roll diameter D is generated in accordance with the position of the scraping scraper 36 of the scraping scraper roll 37 due to uneven winding of the outer circumferential surface 36a of the scraping scraper roll 37, I can think. It is also conceivable that the punching scraper roll 37 is eccentrically wound around the paper tube 64 or vibrated. As a result, there is a possibility that the tension applied to the punch scrap 36 varies and the punch scrap 36 is cut.

In view of the above, it is preferable that the position of the scraping-up shaft 51 is located at a position where the scraping-off path is usually short, and the uneven-winding is not generated. The scraper take-up shaft 51 is positioned such that the outer peripheral surface 36a of the scraping roll 37 is engaged with the outer peripheral surface 47a of the fixed type peeling roller 47, It is determined at a position such that it is close enough not to be. Or the position of the scraping up shaft 51 at a position where the outer circumferential surface 36a of the scraping scraping roll 37 slightly contacts the outer circumferential surface 47a of the stationary peeling roller 47, Is determined.

Here, by applying tensile force to the punch scrap 36, the punch scrap 36 shrinks in the width direction.

For example, when the punch scrap 36 is omitted in the form of a lattice, the punch scrap 36 has a conveying direction belt-shaped portion 361 and a widthwise belt-shaped portion 362. The conveying direction belt-like portion 361 of the punch scrap 36 is wound around the scraping-up shaft 51 in a state of being stretched in the conveying direction by the tension and contracted in the width direction. In this case, the width-direction belt-shaped portion 362 of the lattice-shaped pulling scrap 36 is wound around the scraping-up shaft 51 in a state in which no tensile force acts on the strip-shaped portion 361, .

Therefore, the roll diameter D (see Fig. 2) of the widthwise strip-shaped portion 362 of the scraping roll 37 is larger than the roll diameter D of the conveying direction strip-shaped portion 361. [ The roll diameter D of the widthwise strip-shaped portion 362 of the punching scrap roll 37 and the roll diameter D of the conveying direction strip-shaped portion 361 of the punch scraping roll 37 have the same diameter, 103 (see Fig. 2).

The scraping up shaft 51 is moved to a position close to the stationary peeling roller 47 so that the outer circumferential surface 36a of the scraping scraping roll 37 does not contact the outer circumferential surface 47a of the stationary peeling roller 47, Can be determined. The scraping up of the scraping up shaft 51 is performed at a position such that the outer peripheral surface 36a of the scraping scraper roll 37 slightly contacts the outer peripheral surface 47a of the stationary peeling roller 47, The position can be determined.

11, the distance r between the outer circumferential surface 36a of the scraping scraper roll 37 and the outer circumferential surface 47a of the stationary peeling roller 47 is set to be in the range of usually 0.0 to 5.0 mm . However, depending on the roll shape of the scraping roll 37, it is also possible to change the setting of the interval r so that the interval r is 5.0 mm or more. The initial position of the scraping-up shaft 51 becomes the position shown in the state (A) of Fig. The initial position of the scrap-up shaft 51 refers to the position of the scrap-up shaft 51 in a state where the scrap 36 of the label 34 is not wound on the branch tube 64 fixed to the scrap- .

3), the outer peripheral surface 64a of the branch tube 64 fixed to the scraping-up shaft 51 is in contact with the outer peripheral surface 47a of the fixed-type peeling roller 47 (see Fig. 11) And is set at a distance as close as possible to the stationary peeling roller 47. Therefore, the punching scrap 36 is wound on the paper tube 64 fixed to the scraping-up shaft 51 as soon as it is peeled off from the paper 31 by the stationary peeling roller 47. The wound punch scrap 36 is integrated with the scrap retracting shaft 51 (i.e., the paper tube 64) by the sticking surface of the punch scrap 36. [

As a result, the distance of the scrap pass of the punch scrap 36 that is transported as a single body is suppressed to be short, and the punch scrap 36 is wound without being cut.

Hereinafter, a method of winding a scraping scraper of a continuous label sheet for reducing the distance of the scraping pass of the scraper 36 conveyed as a unit will be described with reference to Fig.

The shaft position P of the scraping up shaft 51 is first set to the outer peripheral surface 64a of the paper tube 64 and the outer peripheral surface 47a of the fixed type peeling roller 47 as shown in the state (A) Is set so that the distance r between the outer circumferential surface 64a and the outer circumferential surface 47a is close to each other (specifically, the interval r is set in the range of 0.0 to 5.0 mm). The axis position P indicates the distance between the outer circumferential surface 47a of the stationary peeling roller 47 and the center 51a of the scraper uptake shaft 51. [

As shown in the state (B) of FIG. 2 and FIG. 11, when the continuous label sheet 30 is started to be conveyed, the scrap-up shaft 51 rotates in the scrap winding step. The scraping off shaft 51 is rotated so that the scraping scrap 36 separated from the ground 31 (see Fig. 3) is wound around the core tube 64 of the scraping-up shaft 51. [

In the roll diameter calculation process, the roll diameter D of the punch scraping roll 37 is set based on the winding pulse signal from the third sensor 118 (see Fig. 1) or the conveyance pulse signal from the line encoder 119 I ask. The third sensor 118 detects one rotation of the scraping-up shaft 51. The line encoder 119 detects the amount of conveyance of the continuous label sheet 30.

Then, the calculated roll diameter D is stored in the arithmetic unit 22 in the controller 21. The roll diameter obtained by adding the increment of the radial dimension arbitrarily set to the roll diameter D stored in the calculation section 22 is set to the "rising start roll diameter D1" of the punch scrap roll 37 in advance.

As shown in the state (C) of Fig. 2 and Fig. 11, during conveyance of the continuous label sheet 30, the conveyance pulse amount of the line encoder 119 And calculates the roll diameter D of the scraping roll 37 every time.

In the scraping-up shaft moving step, the roll diameter D of the obtained scraping scraper roll 37 is compared with the " rising start diameter D1 ". The second servo motor 82 (see Fig. 1) of the up-and-down moving mechanism 16 is driven based on the signal from the control unit 24 when the compared roll diameter D is larger than the " ascent roll diameter D1 & .

The rotation of the sixth timing pulley is transmitted to the fifth timing pulley 93 of the rotation shaft 89 via the third timing belt 96 by rotating the sixth timing pulley 95 with the second servo motor 82 . As the fifth timing pulley 93 rotates, the pair of driving gears 79 rotate through the rotating shaft 89. [

As the pair of drive gears 79 rotate, the pair of driven gears 78 rotate.

As the pair of driven gears 78 rotate, the pair of ball screws 77 rotate. As the pair of ball screws 77 rotate, the connecting bracket 92 (that is, the moving body 76) moves in the vertical direction.

A winding mechanism 14 is attached to the first table 85 and the second table 86 of the moving body 76. The movable body 76 is moved up and down so that the scraping up shaft 51 is moved up to the axial position P by the scraping-up shaft lift setting value of the scraping-up shaft 51 which is arbitrarily set. That is, the scraping-up shaft 51 is moved in the direction away from the stationary peeling roller 47.

11, the distance r between the outer circumferential surface 36a of the scraping scraping roll 37 and the outer circumferential surface 47a of the fixed separating roller 47 is smaller than the distance r between the scraping roll 37 The distance between the outer peripheral surface 36a of the fixed separation roller 47 and the outer peripheral surface 47a of the fixed separation roller 47 is close to the fixed separation roller 47. [

After the raising operation of the scraping-up shaft 51 is completed, the roll diameter D of the scraping-off roll 37 is calculated again in the same manner. The new "rising start roll diameter D1" of the scrap-up take-up shaft 51 is determined by overwriting the roll diameter D on the calculating section 22. [ The scraping up shaft 51 is lifted on the basis of the signal from the control unit 24 as well.

That is, the control section 24 moves the scraping up shaft 51 in the direction away from the stationary peeling roller 47 or in the direction close to the stationary peeling roller 47, based on the roll diameter D obtained from the calculating section 22 The vertical movement mechanism 16 is controlled.

Next, an example of moving the scraping-up shaft 51 in the direction away from the stationary peeling roller 47 in the control section 24 will be described in detail with reference to Figs. 11 and 12. Fig.

The state (A), state B and state C in Fig. 11 are the state in which the scraping up shaft 51, the scraping scrap roll 37, the stationary peeling roller 47 at the time of A, B, Fig. 12 is a graph showing an example of the rise timing of the scraping-up shaft 51 when the take-up scraping operation is performed.

11, the distance r is a distance between the outer circumferential surface 36a of the scraping roll 37 and the outer circumferential surface 47a of the stationary peeling roller 47 or the distance between the outer circumferential surface 64a of the paper tube 64 and the stationary peeling roller 47. [ And the outer circumferential surface 47a of the outer cylinder 47. As described above, the shaft position P indicates the distance between the outer circumferential surface 47a of the stationary peeling roller 47 and the center 51a of the scraping-up shaft 51. [

12, the pipe diameter of the branch pipe 64 is larger than the rising start roll diameter D1 at the point of time when the scrap-up shaft 51 has the rotational speed A (A = 0) . For example, the branch tube 64 is set to have a tube diameter of 100 mm. The gap r is maintained between the outer circumferential surface 64a of the paper tube 64 and the outer circumferential surface 47a of the stationary peeling roller 47. [ The punching scraper 36 is wound around the core tube 64 of the scraping-up shaft 51 while the scraping-up shaft 51 is not lifted.

11, the roll diameter D of the punch scrap roll 37 is increased by winding the punch scrap 36 on the paper tube 64 of the scrap-up pivot shaft 51, as shown in Fig. At the same time, the distance r between the outer circumferential surface 36a of the scraping roll 37 and the outer circumferential surface 47a of the stationary peeling roller 47 becomes small

The roll diameter D of the punch scraping roll 37 exceeds the " rising start roll diameter D1 " in a state in which the scraping up shaft 51 reaches the rotation speed B.

The scrap-up shaft 51 starts to rise. During the lifting of the scraping-up shaft 51, the scraping scraper 36 is continuously wound on the scraping-up shaft 51. The punch scrap 36 is continuously wound on the paper tube 64 of the scraper take-up shaft 51 so that the roll diameter D of the punch scrap roll 37 becomes large. In this state, the scrap-up shaft 51 is raised. The distance r between the outer circumferential surface 36a of the scraping scraping roll 37 and the outer circumferential surface 47a of the stationary peeling roller 47 is increased toward the preset scrap retracting shaft elevation set value.

As shown in Fig. 11 (C) and Fig. 12, when the scrap-up take-up shaft 51 is at the rotation speed C, the rising value of the scrap- (For example, 5.0 mm). Therefore, the scrap-up shaft 51 stops rising. A roll diameter obtained by adding an arbitrarily set increase in diameter dimension (for example, 3.0 mm) to the roll diameter D when the scrap-up shaft 51 stops rising is defined as a new rising start roll diameter D1. Thus, the scraping scraper 36 is wound up without raising the scraping-up spool shaft 51 until the roll diameter D reaches the rising start roll diameter D1.

As described above. The interval r between the outer circumferential surface 36a of the scraping scraping roll 37 and the outer circumferential surface 47a of the stationary peeling roller 47 is normally 0.0? R? 5.0 mm. < / RTI >

Therefore, it is possible to maintain the position at which the outer circumferential surface 36a of the scraping roll 37 comes close to the stationary peeling roller 47 or the position slightly tangent to the extent that the outer circumferential surface 36a of the scraping roll 37 does not contact the outer circumferential surface 47a of the stationary peeling roller 47 have. As a result, the punching scrap (36) is not cut and the stable punching scraper (36) can be wound.

Thus, the scrap-up shaft 51 can be moved in the direction away from the stationary peeling roller 47 or in the direction close to the stationary peeling roller 47 based on the roll diameter D of the scraping roll 37 . Therefore, the distance r between the outer circumferential surface 36a of the scraping roll 37 and the outer circumferential surface 47a of the stationary peeling roller 47 can be suppressed to be small (the spacing r also includes zero). That is, the scrap path dimension from the outer circumferential surface 47a of the stationary peeling roller 47 to the outer circumferential surface 36a of the scraping scraper roll 37 can be reduced.

As a result, even when the predetermined shape of the label 34 is circular or irregular other than the rectangular shape, the tension generated in the take-off scraper 36 during winding can be stabilized, have.

In addition, by suppressing the scrap path dimension from the outer circumferential surface 47a of the stationary peeling roller 47 to the outer circumferential surface 36a of the scraping scraper roll 37 to be small, a strong tension is applied to the scraping scraper 36 It is possible to prevent the breaking scrap 36 from being cut off.

Further, by suppressing the cutting of the scraping scrap 36, the printing speed of the continuous label sheet 30 can be increased. As a result, the productivity of the label 34 can be greatly improved.

In the present embodiment, the increment of the radial dimension is set to 3.0 mm and the scrap retractable shaft lift set value is set to 5.0 mm. However, the increment of the radial dimension and the scrap retractable shaft lift set value are limited to 3.0 mm or 5.0 mm no. The outer circumferential surface 64a of the paper tube 64 fixed by the lug 62 or the outer circumferential surface 36a of the scraping roll 37 and the outer circumferential surface 47a of the stationary peeling roller 47 are fixed to the scrap- It is sufficient that the scraping-up shaft 51 is raised so that the interval r remains within a certain range.

As another example, for example, the thickness dimension of the continuous label sheet 30 may be measured before the start of winding, and the scrap up axis lift set value may be changed in accordance with the value. Further, the value may be changed according to the type of the continuous label sheet 30 or the winding speed.

The up-and-down moving mechanism 16 of the scraping-up spool shaft 51 is capable of moving the scraping-up spool shaft 51 manually up and down It is also possible to operate it.
