Description

  The present invention relates to a residue peeling mechanism, a medium winding device, and a printing system.

  2. Description of the Related Art Conventionally, in a printing system including a printer that performs printing on a long label material, and a label winder as a medium winder disposed adjacent to the printer, the label material is printed by the printer. After an image is formed on each label piece in the section, the image is discharged out of the printer, supplied to a label take-up device, and taken up by a take-up roller.

  And as a label raw material, the label base material was temporarily attached to the label mount via an adhesive, and the cut of the shape of the label piece was formed by performing a half-cut process on the label base material and the adhesive. Things are offered.

  FIG. 2 is a cross-sectional view showing an example of the label material, and FIG. 3 is a plan view showing an example of the label material.

  In the figure, P is a label raw material. A label base material 93 is temporarily attached to the label base material 91 via an adhesive 92 on the label raw material P, and the label base material 93 and the adhesive 92 are cut with a cutting blade. By performing half-cut processing, cuts 96 in the shape of a plurality of label pieces 95 are formed.

  In this type of label raw material P, by forming the cut 96 having the shape of the label piece 95, a portion other than the label piece 95 in the label base material 93 and the adhesive 92 is formed as a residue Pa. When the label piece 95 has a rectangular shape, the residue Pa includes a longitudinal direction portion Sa extending in the longitudinal direction of the label material P and a width direction portion Sb extending in the width direction of the label material P. Note that Sc is a corner portion where the longitudinal direction portion Sa and the width direction portion Sb of the residue Pa intersect.

  By the way, when forming the label paper as a label product using the label raw material P, it is preferable to leave only the label piece 95 on the label mount 91.

  Therefore, a debris peeling mechanism for removing debris Pa in the label raw material P is arranged in the label winder (see, for example, Patent Document 1).

  In the residue peeling mechanism, a release member made of an elastic member is brought into contact with the label base material 93 to be conveyed, and the residue Pa is peeled off from the label mount 91 in a folded manner.

  However, in the conventional waste peeling mechanism, the waste Pa cannot be removed smoothly.

  That is, as described above, in the waste Pa, there are portions having different extending directions such as the longitudinal direction portion Sa and the width direction portion Sb, but when the waste Pa is peeled off from the label mount 91, The tension (tension) applied to the residue Pa may be different between the longitudinal direction portion Sa and the width direction portion Sb. In this case, the residue Pa is peeled off with an equal force between the longitudinal direction portion Sa and the width direction portion Sb. Is difficult, and the residue Pa is deformed and peeled off.

  Further, if there is a variation in the state of the half-cut processing for the label raw material P, a portion where the notch 96 is not completely formed may occur. In this case, when the residue Pa is peeled off from the label mount 91, the residue Pa At the same time, the phenomenon that the label piece 95 is peeled off, that is, the co-up occurs, and the waste Pa may break at the corner portion Sc and remain on the label mount 91 or the label piece 95 may not remain on the label mount 91. is there.

  As a result, the waste Pa in the label raw material P cannot be removed smoothly, and the quality of the label paper is lowered.

  The present invention solves the problems of the conventional debris peeling mechanism, and can smoothly remove debris from the label raw material, and can improve the quality of the label paper. The purpose is to provide a system.

  Therefore, in the residue peeling mechanism of the present invention, in the label raw material in which the cut in the shape of the label piece is formed by half-cut processing, a residue removal portion for removing residue that is a portion other than the label piece, and the residue There is a waste transporting member that transports the waste removed by the peeling unit, and a label paper transporting member that transports the label paper having the label piece on the label mount after the waste is removed.

  The debris peeling portion is rotatably disposed and is rotated in accordance with the conveyance of the label raw material. The delamination portion roller is disposed so as to face the separation portion roller, and is for peeling off the debris from the label mount. And a pressing unit disposed on the upstream side of the peeling member in the rotation direction of the peeling member roller and pressing the label raw material against the peeling roller.

  According to the present invention, in the debris peeling mechanism, the debris peeling portion for removing debris that is a portion other than the label piece in the label raw material in which the cut of the shape of the label piece is formed by half-cut processing, There is a waste transporting member that transports the waste removed by the peeling unit, and a label paper transporting member that transports the label paper having the label piece on the label mount after the waste is removed.

  The debris peeling portion is rotatably disposed and is rotated in accordance with the conveyance of the label raw material. The delamination portion roller is disposed so as to face the separation portion roller, and is for peeling off the debris from the label mount. And a pressing unit disposed on the upstream side of the peeling member in the rotation direction of the peeling member roller and pressing the label raw material against the peeling roller.

  In this case, since the pressing unit that presses the label raw material against the peeling portion roller is disposed upstream of the peeling member in the rotation direction of the peeling portion roller in the waste peeling portion, the waste is not deformed and peeled off.

  Further, there is no possibility that the residue is broken and remains on the label mount, or the label piece does not remain on the label mount.

  Therefore, the residue in the label raw material can be removed smoothly, and the quality of the label paper can be increased.

  The label winding device 13 is movable up and down along a housing Hs (not shown) serving as a drive unit, a housing Hs that accommodates a rotation transmission system, and a slit 17 formed in the front panel 15 of the housing Hs. In addition, the tension bar 18 that is rotatably arranged, the waste peeling part 106 for removing the waste Pa in the label raw material P, and the waste winding mechanism for winding the waste Pa removed by the waste peeling part 106 A label paper take-up mechanism 111 for taking up the label paper Pb having the label pieces 95 on the label mount 91 after the part 109 and the waste Pa are removed is provided. The slit 17 is formed to extend in the vertical direction at an end of the front panel 15 on the printer 12 side, and the residue peeling portion 106 is disposed adjacent to the slit 17 at the center of the front panel 15. The residue winding mechanism 109 is disposed above the residue peeling portion 106 of the front panel 15, and the label sheet winding mechanism 111 is disposed below the residue peeling portion 106 of the front panel 15.

  The residue peeling mechanism 106, the residue take-up mechanism 109, the label sheet take-up mechanism 111, and the like constitute a residue removal mechanism. Further, the waste take-up mechanism 109 constitutes a waste transport member for transporting the waste Pa removed by the waste peeler 106, and the label paper for transporting the label paper Pb by the label paper take-up mechanism 111. A conveying member is configured.

  The scrap peeling unit 106 is disposed on the downstream side of the tension bar 18 in the conveyance direction of the label raw material P so as to protrude from the front panel 15 and be freely rotatable. The peeling unit roller is rotated in accordance with the conveyance of the label raw material P. The idle roller 16 is projected from the front panel 15 and is rotatably disposed above the idle roller 16 so as to face the idle roller 16 and peels off the waste Pa from the label mount 91 in the label raw material P. For this purpose, the peel bar 35 serving as a peeling member is protruded from the front panel 15 and is rotatably disposed so as to face the idle roller 16, and the label paper Pb after the residue Pa is removed is removed from the idle roller 16. A guide roller 36 and the like approaching the side are provided.

  Further, the waste take-up mechanism 109 protrudes from the front panel 15 and is rotatably arranged, and with the rotation, the waste take-up Pa is peeled off from the label mount 91 by the peel bar 35 to take up a waste. A raising roller 37 is provided. In addition, in the housing Hs, a waste raising motor (not shown) serving as a waste raising drive unit 37 is connected to the waste raising roller 37, and the waste Pa is wound up in a roll shape by driving the waste raising motor. It is done.

  The label paper take-up mechanism 111 is provided so as to be rotatable from the front panel 15 and includes a take-up roller 38 for taking up the label paper Pb in a roll shape along with the rotation. In the housing Hs, a winding motor (not shown) serving as a winding driving unit is connected to the winding roller 38, and the label paper Pb is wound in a roll shape by driving the winding motor. Taken.

  By the way, when the tension applied to the label paper Pb between the idle roller 16 and the take-up roller 38 is reduced while the waste Pa is peeled off from the label mount 91, the waste paper Pa causes the label mount 91 to move toward the residue raising roller 37 side. As a result, the residue Pa cannot be peeled off smoothly from the label mount 91, and the residue Pa may break. Therefore, in the present embodiment, the guide roller 36 is disposed so as to face the idle roller 16, and the label paper Pb is moved toward the idle roller 16 by the guide roller 36, so that the waste Pa is smoothly removed from the label mount 91. It can be peeled off.

  The position of the tension bar 18 is changed according to the tension applied to the label material P between the printer 12 and the idle roller 16. That is, the tension bar 18 is raised when the tension applied to the label material P continues, and is lowered by its own weight when the tension is not applied to the label material P. A plurality of sensors (not shown) as detection units are arranged along the slit 17. The position of the tension bar 18 is detected by each sensor, and when the tension bar 18 is placed at the lower position, the winding motor Is driven, the take-up roller 38 is rotated, the label paper Pb is taken up, the tension bar 18 is raised, and when the tension bar 18 is placed in the upper position, the take-up motor is stopped and the take-up motor is stopped. The take-up roller 38 is stopped and the tension bar 18 is lowered.

  Each sensor, the slit 17, the tension bar 18 and the like constitute a conveyance adjusting unit that adjusts the conveyance of the label raw material P between the label winder 13 and the printer 10.

  Incidentally, as shown in FIG. 3, the residue Pa has a portion extending in a different direction, such as a longitudinal direction portion Sa and a width direction portion Sb, but the residue Pa is peeled off from the label mount 91. In some cases, the tension applied to the residue Pa may be different in each part of the label raw material P, in the present embodiment, in the longitudinal direction portion Sa and the width direction portion Sb. And the width direction portion Sb are difficult to peel off with an equal force, and the residue Pa is deformed and peeled off.

  Further, if there is a variation in the state of the half-cut processing for the label raw material P, there may be a portion where the cut 96 is not completely formed. In this case, the co-up occurs and the residue Pa breaks at the corner portion Sc. As a result, the label mount 91 may remain, or the label piece 95 may not remain on the label mount 91.

  Therefore, in the present embodiment, a pressing unit 20 that presses the label material P against the idle roller 16 is disposed adjacent to the peel bar 35 on the upstream side of the peel bar 35 in the rotational direction of the idle roller 16.

  Next, the pressing unit 20 will be described.

  FIG. 4 is a diagram showing details of the residue peeling portion in the embodiment of the present invention, FIG. 5 is a first perspective view for explaining the operation of the residue peeling portion in the embodiment of the present invention, and FIG. It is a 2nd perspective view for demonstrating the operation | movement of the residue peeling part in embodiment of this.

  In the figure, 16 is an idle roller rotated in the direction of arrow B, P is a label raw material, Pa is a waste conveyed in the direction of arrow C, Pb is label paper, 35 is a peel bar, 20 is a peel bar in the rotational direction of the idle roller 16. 35 is a pressing unit disposed on the upstream side of 35.

  The peel bar 35 includes a shaft sh1 disposed so as to protrude from the front panel 15 (FIG. 1), and a roller 21 as a cylindrical body disposed so as to be rotatable relative to the shaft sh1. The position of the shaft sh1 is set so that a predetermined distance is placed between the roller 21 and the label raw material P.

  The pressing unit 20 is disposed so as to be swingable about the peel bar 35. For this purpose, the pressing unit 20 protrudes toward the upstream side in the rotational direction of the idle roller 16 at both ends of the roller 21 and is a pair of arm portions that are swingably disposed with respect to the peel bar 35. Arm 22, shaft sh 2 connecting the tips of the arms 22, a pair of pressing rollers 24 as a first pressing member rotatably disposed by the shaft sh 2, and adjacent to the pressing rollers 24. A pair of pieces 25 having a cubic shape and supported so as to be movable (slidable) in the direction of arrow D, that is, in the width direction of the label raw material P by the shaft sh2, and the idle roller 16 A second pressing member that extends toward the downstream side in the rotation direction and is movably disposed in the width direction of the label raw material P, like the piece 25. Having a flap 26 or the like as a member.

  Each of the arms 22 is disposed at a predetermined position on the shaft sh1, in this embodiment, at a portion adjacent to both ends of the roller 21 on the shaft sh1 so as to face the end surface of the roller 21 and relatively to the shaft sh1. It is rotatably arranged.

  The shaft sh2 extends parallel to the shaft sh1, and has a small-diameter cylindrical shaft portion ma as a first support portion formed by extending a predetermined distance from both ends to the center, and each cylindrical shaft. A two-surface cut shaft portion mb is provided as a second support portion that is formed so as to extend between the portions ma and has flat surfaces formed at two locations in the circumferential direction. The pressing roller 24 is disposed on each cylindrical shaft portion ma so as to be relatively rotatable with respect to the shaft sh2. The pieces 25 are mounted on both ends of the two-surface cut shaft portion mb with respect to the shaft sh2. It is arranged so as to be movable in the axial direction and slidable.

  The flap 26 is formed of a material that has flexibility and elasticity, and that flexes flexibly under external force, in the present embodiment, a resin film (for example, a polyester resin film). 25, in the present embodiment, it is attached in a cantilever manner to the edge portion eg on the lower surface facing the roller 21.

  Reference numeral 27 denotes a fixing knob. The fixing knob 27 includes a knob 31 and a screw part 32 extending downward from the knob 31. The screw part 32 and a screw hole formed in the piece 25 are screwed together. In the screw hole, the screw portion 32 and the flat surface on the upper side of the two-surface cut shaft portion mb can be brought into contact with each other. When the knob 31 is rotated to tighten the screw portion 32 and the screw hole, the screw portion 32 is pressed against the flat surface on the upper side of the two-surface cut shaft portion mb in the screw hole, and the piece 25 is against the shaft sh2. When the knob 31 is rotated to loosen the screw portion 32 and the screw hole, the screw portion 32 moves away from the flat surface on the upper side of the two-surface cut shaft portion mb in the screw hole, and the piece 25 Is made movable relative to the shaft sh2.

  The pressing roller 24 and the piece 25 are moved in the vertical direction (the radial direction of the idle roller 16) with the center of the peel bar 35 as a fulcrum according to the thickness of the label raw material P as the arm 22 swings.

  Further, the pressing roller 24 is brought into contact with the label raw material P with the weight of the pressing unit 20 in the vertically downward direction of the center, and is rotated along with the conveyance of the label raw material P, so that a predetermined portion of the label raw material P is In the present embodiment, the longitudinal direction portion Sa of the residue Pa is pushed toward the idle roller 16.

  The tip of the flap 26 is brought into contact with the label material P in the vertically downward direction at the center of the peel bar 35 as shown by a virtual circle γ in FIG. The width direction portion Sb and the label piece 95 are moved to the idle roller 16 with a predetermined urging force, at a predetermined location of the label raw material P, in the present embodiment, in the central side from the longitudinal direction portion Sa of the residue Pa. Push towards.

  In addition, it is preferable to make the front-end | tip of the said flap 26 adjoin the longitudinal direction part Sa in the center side rather than the longitudinal direction part Sa of the residue Pa. In the present embodiment, since the piece 25 is disposed so as to be movable in the width direction of the label raw material P with respect to the shaft sh2, the piece 25 is made of the label raw material P according to the size, shape, etc. of the label piece 95. By moving in the width direction, the tip of the flap 26 can be placed at a position adjacent to the longitudinal direction portion Sa of the residue Pa.

  Next, the operation of the label winding device 13 will be described.

  When printing is performed in the printer 12 (FIG. 1) and the label material P on which an image is formed on each label piece 95 is discharged from the discharge port 14 and supplied to the label winder 13, the label material P is A slack occurs between the printer 12 and the idle roller 16 so as to change from the state shown by the broken line in FIG. 1 to the state shown by the solid line, and the tension bar 18 is lowered accordingly. When the tension bar 18 is placed in the lower position and the sensor detects the tension bar 18, the winding motor disposed in the label paper winding mechanism 111 is driven to start winding the label paper Pb. .

  In the present embodiment, the winding speed by the winding roller 38 is set to be higher than the conveyance speed of the label material P in the printing unit of the printer 12, so that when the winding by the winding roller 38 is continued, the label The slack of the raw material P disappears, and the tension bar 18 rises. Subsequently, when the tension bar 18 is placed in the upper position and the sensor detects the tension bar 18, the driving of the winding motor is stopped, and the winding of the label paper Pb is stopped. As a result, the label material P is slackened again, and the tension bar 18 is lowered accordingly.

  Then, the operation of the tension bar 18 and the label paper take-up mechanism 111 in the label take-up device 13 is repeated until the printing is finished in the printer 12 and the discharge of the label raw material P is finished, and the label paper Pb is taken up. Is called.

  Next, a scrap raising operation in which the scrap Pa is peeled off from the label mount 91 and wound around the scrap raising roller 37 will be described.

  When the label raw material P is sent to the residue peeling unit 106, the residue Pa is peeled off from the label mount 91 by the peel bar 35 and is sent to the residue take-up mechanism 109 in the direction of arrow C.

  At this time, the pressing roller 24 is rotated with the conveyance of the label raw material P on the upstream side of the peel bar 35 in the rotation direction of the idle roller 16, and pushes the longitudinal direction portion Sa of the residue Pa toward the idle roller 16. Further, the flap 26 is slid with the label raw material P in the vertically downward direction at the center of the peel bar 35, and the width direction portion Sb at a position adjacent to the longitudinal direction portion Sa on the center side of the longitudinal direction portion Sa of the residue Pa. The label piece 95 is pushed toward the idle roller 16.

  Therefore, when the waste Pa is peeled off from the label mount 91, both edges of the label raw material P, that is, the respective longitudinal direction portions Sa are pushed toward the idle roller 16 by the pressing roller 24, so that the tension applied to the waste Pa is long. It is possible to prevent the difference between the direction portion Sa and the width direction portion Sb. As a result, the residue Pa can be peeled off with a uniform force between the longitudinal direction portion Sa and the width direction portion Sb, so that the residue Pa is not deformed and removed.

  Further, even if there is a variation in the state of half-cut processing for the label raw material P and a portion where the notch 96 is not completely formed is generated, the label piece 95 is pushed toward the idle roller 16 by the flap 26. Ascending does not occur, and the waste Pa does not break at the corner portion Sc and remains on the label mount 91, or the label piece 95 does not remain on the label mount 91.

  Therefore, the residue Pa can be removed smoothly from the label raw material P, and the quality of the label paper Pb can be increased.

  In addition, this invention is not limited to the said embodiment, It can change variously based on the meaning of this invention, and does not exclude them from the scope of the present invention.
