Description
Technical field
The present invention relates to a kind of label peeling mechanism, this label peeling mechanism is bent back to himself ground by roll web from the no label-side of roll web liner with acutangulating transmits label paper, and from being stained with the roll web liner peeling label of label.The invention still further relates to a kind of have be used for being printed the back at label, from the label machine of the label peeling mechanism of roll web liner peeling label.
Background technology
Usually, the label machine that printing and discharge label are used prints to the rolling label paper, and this rolling label paper comprises the chart drum liner of the bonding label of the regular length with the side (being called " front " herein) that strippingly invests chart drum.This label machine transmits label paper, arrives the print position of printing mechanism Print Label up to label.Then, label paper is sent to label peeling mechanism downstream, breaks away from chart drum from Print Label, and label of peeling off then and chart drum liner are discharged from the emission path that separates.Typical label peeling mechanism is through the path of (no label-side) crooked roll web from its back side, transmit the roll web of having label on it by the angle that is less than or equal to 90 degree, and the rigidity rigidity of plane (break away from) of utilizing label is with the leading edge from each label, gradually from the liner separation tags.For example, at the open H4-272876 of Japanese unexamined nuclear patent application the printer with this type of label peeling mechanism has just been described.
This type of label peeling mechanism has and is set up around 90 degree or more low-angle bight with roll web guide crooked and the guiding roll web liner back side, and transmits the roll web liner of this roll web guide of contact.It is more little that the roll web liner transmits the radius of curvature of passing through, and just can get over reliably from the liner peeling label.
When label paper was provided with rolling, label was rolled into volume with the continuous roll web liner that fixed intervals invest its surface.Label utilizes adhesive to invest the surface of roll web, even and after label was peeled off from roll web, adhesive can be left on the surface of roll web.A little binder also appears at around the label area that invests roll web.The transfer path part that this can cause adhesive to be sent to contacting with label surface with roll web.Along with the like this accumulation of adhesive on drive access, roll web and label can tend to adhere to these drive access parts that become sticky at present.For example, this makes to be difficult to transmit and is used for the pinpoint roll web of label, also can cause paperboard and other problem.
Summary of the invention
An advantage according to label peeling mechanism of the present invention is: can prevent the paperboard or the other problem that are caused by the adhesive that adheres to drive access, and therefore roll web liner and label can be transmitted reliably.Label machine with this label peeling mechanism according to the present invention also has same advantage.
For realizing above-mentioned target, label peeling mechanism according to the present invention has: have the roll web curved guide device of convex surfaces, it is used for front surface with the continuous roll web of label to crooked 90 degree in the back side of this roll web or low-angle more; The upstream roll web is pushed guide, its be arranged on roll web curved guide device guide surface part the opposite, from the upstream of the roll web direction of transfer of convex curved surface; Push guide with the downstream roll web, its be arranged on roll web curved guide device guide surface part the opposite, from the downstream of the roll web direction of transfer of contact surface.Be used to contact a plurality of contact portions on the surface of roll web, with a certain gap, cross web width, be set to the upstream roll web and push guide and downstream roll web and push at least one place in the guide perpendicular to the roll web direction of transfer.Roll web is pushed between the guide at upstream guide surface part and upstream roll web and is transmitted; Around crooked 90 degree or the littler angles of convex curved surface; Transmit and push between the guide at downstream guide surface part and downstream roll web then.Along with label transmits around convex curved surface with being bent, label is stripped from from roll web.The upstream roll web is pushed guide and is pushed the upstream side extension of guide along the roll web throughput direction along extension of roll web conveyance direction downstream side or downstream roll web.
Direction of transfer along roll web, guide pushed by the upstream roll web that this label peeling mechanism has a upstream and downstream side of convex curved surface and the downstream roll web is pushed guide, with prevent roll web climb away the projection curved surface, thereby roll web is transmitted through less radius of curvature.Therefore, along with roll web is advanced around this convex curved surface, label is peeled off from roll web reliably.Guide pushed by the upstream roll web of front surface of contact roll web and the downstream roll web is pushed guide, has roll web when being transmitted, at the contact site of the limited position contact roll web of the width that crosses roll web.Like this, can make the surface contact area minimum with roll web and label, and prevent that the upstream roll web from pushing the accumulation that guide and downstream roll web are pushed adhesive on the guide.
In addition, even adhered to contact portion from the adhesive of web surfaces, in conjunction with the transmission of roll web, adhesive also can move to the gap therebetween vertical with roll web from these contact portions gradually.Therefore, prevent the accumulation of adhesive on these contact portions, prevent problem, and can transmit roll web smoothly such as paperboard.
More preferably, contact portion is formed with rib, and described rib has conical surface on the both sides of the far-end of contact roll web, and it forms the taper section that narrows down gradually to the far-end of rib from the bottom.
Alternatively, contact portion is formed with roller, and described roller has conical surface on the both sides of the outer peripheral end of contact roll web, and it forms the taper section that narrows down gradually to the periphery from the bottom.
These rib shapes or roller contact portion reduced the contact area with roll web and label surface, in conjunction with the transmission of roll web, promoted effectively adhesive from the contact portion of width to motion perpendicular to the gap therebetween of roll web; Thereby more effectively prevent the accumulation of adhesive on contact portion.
More preferably, the contact portion that the upstream roll web is pushed guide along with the side of the crooked roll web of roll web curved guide device wherein in the opposite direction, to the downstream bending of the direction of transfer of roll web, and the roll web drive access is narrowed down.
This layout can prevent that roll web from the upstream side along the convex curved surface of roll web direction of transfer, lifting away from convex curved surface, and can transmit roll web through less radius of curvature.In addition, because label is bent surface curvature along the direction that breaks away from roll web, so label just can be peeled off from chart drum more reliably.

The specific embodiment
With reference to accompanying drawing, below the preferred embodiment that has the label machine of label peeling mechanism according to of the present invention will be described.
General structure
Fig. 1 is the outside oblique view of root according to label machine 1 of the present invention; Fig. 2 is the sectional view of display label printer structure; And Fig. 3 is the local amplification view of the label peeling mechanism in the display label printer.
Have according to the label machine 1 among the current embodiment of the present invention: shape is essentially the printer casing 2 of parallelepiped, and label dispenser opening 3 forms at an upper portion thereof; With roll web outlet opening (outlet) 4, it is positioned at the place, bottom of the anterior 2a of printer casing 2.Winding paper chamber * winding paper 5 is formed in the Lower Half of printer casing 2 inside.The coil paper 6 that is used for label printing is loaded in the winding paper chamber * winding paper 5.
The coil paper 6 that is used for Print Label comprises the continuous roll web 8 that is rolled into volume with fixed width, and the label 7 that is generally rectangle is thereon attached at interval with rule.Unshowned adjustable paper guide is set at label machine 1 inside (for example in winding paper chamber * winding paper 5), with the width of control coil paper 6 and roll web 8, and can be set to the width of the coil paper 6 in the use.
Attention: in Fig. 2, represent the transfer path of roll web 8 when using mechanism for stripping 20, and represent the transfer path of label 7 when using mechanism for stripping 20 by label 7 expression dotted lines by the chain-dotted line of label 8 expressions.
The attached roll web 8 thereon of label, the coil paper 6 that is loaded in certainly in the winding paper chamber * winding paper 5 transmits through transfer path 11; Remain between air roll 13 and the thermal printing head 12; And the rotation of passing through air roll 13 transmits.Label 7 is attached to the front side 8a of roll web 8.Behind printhead 12 Print Labels 7, roll web 8 transmits by label peeling mechanism 20.
Label peeling mechanism 20 has essence bends to acute angle with v-shaped structure roll web curved guide device 21.When roll web 8 transmitted around the summit of this roll web curved guide device 21, Print Label 7 was peeled off from roll web 8 gradually from its leading edge, and discharges from label dispenser opening 3.
As the stripper roll 22 of label peeling mechanism 20 parts, be set at the downstream of roll web 8 drive access, in air roll 13 and a certain positions printhead 12 opposite sides.When label peeling mechanism 20 was closed, stripper roll 22 was forced into the outer surface of air roll 13, thereby rotated along with the rotation of air roll 13.After label 7 was peeled off from roll web 8, roll web 8 advanced along roll web curved guide device 21, and was kept by air roll 13 and stripper roll 22.The rotation of air roll 13 will be sent to the front portion of printer around the roll web 8 of the outside of stripper roll 22, and roll web 8 is discharged from roll web outlet 4 like this.
Label peeling mechanism
Hereinafter with reference to Fig. 2 and Fig. 3, description is used for peeling off the label peeling mechanism 20 of Print Label 7 from roll web 8.
The roll web curved guide device 21 of label peeling mechanism 20 has the curved surface 21a that forms endways.This curved surface 21a is the convex curved surface that has than small curvature radius.The smooth upstream upstream side end points 21b of guide surface 21c along the roll web direction of transfer from curved surface 21a smoothly extends.The smooth downstream downstream end points 21d of guide surface 21e along roll web 8 direction of transfers from curved surface 21a smoothly extends.
The upstream side roll web is pushed the opposite side that guide 23 is set at upstream guiding surface 21c, and has a plurality of ribs 31 that cross the web width setting with specific interval.The downstream roll web is pushed the opposition side that guide 24 is set at downstream guiding surface 21e similarly, and has a plurality of guide reels 32 that cross web width with specific interval.The distance that upstream guide surface 21c and upstream roll web are pushed between the rib 31 of guide 23 is more bigger than the gross thickness of roll web 8 and label 7.
Utilization has the upstream rib 31d of protruding arc (it is along the rightabout bending by the direction of roll web curved guide device 21 crooked roll webs), and this gap is made from the upstream of roll web direction of transfer downstream that side narrows down gradually.This has roll web 8 is pressed onto effect on the roll web curved guide device 21 of upstream side of drive access.
More particularly, the straight line L1 of the center of curvature 25 of the curved surface 21a of rib 31d in upstream in connect determining this drive access and end points 21b near push roll web 8 at the upstream side of the curved surface 21a of roll web curved guide device 21; And roll web 8 is pushed near guide reel 32 downstream at the curved surface 21a of the roll web curved guide device 21 straight line L2 that connects the center of curvature 25 and end points 21d.This roll web 8 is pressed against on two points of the upstream side (L1) of curved surface 21a of roll web curved guide device 21 and downstream (L2).This structure can prevent that roll web 8 is outstanding from curved surface 21a, and can transmit roll web 8 through less radius of curvature.
In addition, along with sweep and the rib 31 of roll web 8 through upstream rib 31d transmits, the direction that label 7 edges break away from roll web 8 is along this sweep bending, and therefore label 7 can be peeled off from roll web 8 more reliably.Slightly to back side bending, upstream rib 31d also is directed to roll web 8 the curved surface 21a of roll web curved guide device 21 by roll web 8, and roll web 8 acutangulates bending around this curved surface 21a then.This structure can transmit roll web 8 by less radius of curvature by ditch.
The rib 31 that the upstream roll web is pushed guide 23 extends to the downstream of roll web direction of transfer, exceeds a certain length-specific of upstream side 21b of the curved surface 21a of roll web guide 21.More particularly, these ribs 31 extend downstream from the straight line L1 of the center of curvature 25 of connection end point 21b and definite curved surface 21a.
The outer surface of pushing the guide reel 32 in the guide 24 at another (being the downstream) roll web is along the roll web direction of transfer, from the upstream outstanding a certain length-specific of the downstream end points 21d of curved surface 21a.More particularly, the outer surface of deflector roll 32 is upstream outstanding from the straight line L2 that connects the center of curvature 25 and end points 21d.
In other words, along the roll web direction of transfer, upstream rib 31d is set at a certain position of upstream side, the upstream roll web is pushed on the guide 23, this upstream rib 31d has along with roll web 8 is advanced to curved surface 21a, causes the protrusion arc of roll web 8 convex curved to the face side (label-side) of roll web.These upstreams rib 31d pushes the rib 31 of guide 23 from the upstream roll web, and guiding surface 21c lateral process slightly upstream is so that can make roll web 8 slightly to the rightabout bending of roll web 8 bendings that caused by curved surface 21a.Like this roll web 8 by upstream rib 31d slightly after face side (label-side) bending, roll web 8 is directed into the curved surface 21a of roll web curved guide device 21 then, and along with roll web 8 is advanced and is bent into acute angle around curved surface 21a.Upstream rib 31d is connected to rib 31 smoothly.This roll web 8 is pressed against on two points of the upstream side (L1) of curved surface 21a of roll web curved guide device 21 and downstream (L2).This structure can prevent that roll web 8 is outstanding from curved surface 21a, and can transmit roll web 8 through less radius of curvature.
As shown in Figure 4, the upstream roll web is pushed guide 23 and is had the width that crosses roll web with specific interval, just, and perpendicular to a plurality of ribs 31 (with upstream rib 31d) of roll web direction of transfer setting.Each rib 31 (with upstream rib 31d) has the contact surface 31a that contacts with roll web 8 front side 8a.Conical surface 31b is formed on the both sides of contact surface 31a, so that the width of taper is the narrowest at contact surface 31a place, thereby makes contact area minimum with the front side 8a of roll web 8.Space between every rib 31 (and upstream rib 31d) has formed this upstream roll web and has pushed depression (gap) 31c in the guide 23.The rib 31 (with upstream rib 31d) of the front side 8a of contact roll web 8 is made by not clayization compound or mixture such as silastomer or fluoroplastics.Selectively, can use not clayization compound or mixture that coating is carried out on the surface of rib 31 (with upstream rib 31d) such as silastomer or fluoroplastics.Further alternatively, also can only be coated with not clayization compound such as silicone oil on the surface of rib 31 and upstream rib 31d.Guide reel 32 is also preferably processed to have non-adhering surfaces.Contact the label distributing roller 27 and the label guide reel 28 of the stickup face of label 7 at label distribution opening 3 places, also preferably cannot not carry out stickingly handling.For silicone oil, generally the bonding strength as the acrylic based emulsion of label 7 adhesives is very low.
This label distributing roller 27 can be arranged near the downstream of curved surface 21a of roll web curved guide device 21 with rotating freely.The top of the outer surface of label distributing roller 27 is set in fact that to push the straight line that the rib 31 of guide 23 extends in alignment with the upstream roll web.This label guide reel 28 can be arranged on label dispenser opening 3 sides with rotating freely, near label distributing roller 27.Label guide reel 28 and label distributing roller 27 are located in sustained height in fact.And label guide reel 28 and label distributing roller 27 can keep the label of being stripped from.Adopt this structure, discharge owing to label 7 can separate from roll web 8 fully, label 7 does not need to utilize the tail end that invests roll web 8 to keep, and label 7 can easily be taken away by the user.
The downstream that the downstream roll web is pushed guide 24 is a rib shape guide 29, and its part relative with the downstream guiding surface 21e of roll web curved guide device 21 is the crooked mild arc that leaves roll web curved guide device 21.The rib of guide 29 makes the contact area minimum with the front side 8a of roll web 8.This guide 29 is made by not clayization compound or mixture such as silastomer or fluoroplastics.Alternatively, the not clayization compound coating such as silastomer or fluoroplastics can be used in this surface.Further alternatively, not viscous compound or the mixture such as silicone oil can be coated to this surface.This can prevent that adhesive for labels from adhering to treatment surface.Roll web 8 is by the downstream guiding surface 21e of guide 29 and roll web curved guide device 21 guiding and transmit between the downstream guiding surface 21e of guide 29 and roll web curved guide device 21.
Make by adhesive silicone rubber not as the stripper roll 22 of label peeling mechanism 20 parts.Alternatively, not clayization compound or the mixture coating such as silastomer or fluoroplastics can be used in this surface.Further alternatively, not viscous compound or the mixture such as silicone oil can be coated to this surface.Like this, roll web 8 is kept by stripper roll 22 and air roll 13 and transmits, and is discharged into the front portion of printer from roll web outlet 4.
To shown in Figure 7, the label machine 1 of current embodiment also has the door assembly of opening to the printer front portion around the top of roll web outlet 4 30 according to the present invention as Fig. 6.The stripper roll 22 of label peeling mechanism 20, guide reel 32, label distributing roller 27 and label guide reel 28 all invest this door assembly 30.
The operation of label peeling mechanism
The operation of aforementioned label peeling mechanism 20 from roll web 8 peeling labels 7 below will be described.
Be maintained between printhead 12 and the air roll 13 when having the roll web 8 that invests its surperficial label 7, and when being transmitted by it, printhead 12 prints to specifying information on the surface of blank tag 7.When roll web 8 transmitted between the upstream of roll web curved guide device 21 guiding surface 21c and upstream roll web are pushed the upstream rib 31d of guide 23, roll web 8 was slightly to face side (label-side) bending of roll web, and was sent to curved surface 21a then.Because upstream rib 31d causes roll web 8 to bend towards face side, have of the upstream guiding surface 21c transmission of the roll web 8 of label 7 on it along roll web curved guide device 21, do not leave upstream guiding surface 21c and can not rise.
The distance that the upstream roll web is pushed between guide surface 23 and the upstream guiding surface 21c is more bigger than the gross thickness of roll web 8 and label 7.It is also overlapping with the upstream portion of curved surface 21a that the upstream roll web is pushed guide 23.Thereby label 7 attached roll webs 8 thereon are sent to curved surface 21a along rib 31, do not leave the rib 31 that the upstream roll web is pushed guide 23 and can not rise.
By with specific interval, cross perpendicular to the width of the direction of transfer of roll web 8 and arrange a plurality of ribs 31, make the upstream roll web push contact area minimum between the front side 8a of guide 23 and roll web 8.This makes the more difficult contact surface 31a that transfers to of adhesive on the front side 8a of roll web 8, even and adhesive is sent to contact surface 31a, the lasting transmission of roll web also can make adhesive move into depression (gap) 31c on every rib 31 (with upstream rib 31d) both sides gradually.
Therefore, the adhesive accumulation that the upstream roll web is pushed on roll web 8 contact surfaces of guide 23 is minimum, thereby roll web 8 can successfully transmit.
The outer surface and the curved surface 21a of the guide reel 32 in the downstream roll web guide 24 are overlapping, thereby prevent from roll web 8 to rise and leave curved surface 21a after curved surface 21a bending.Because roll web 8 bends to less radius of curvature by curved surface 21a, label 7 can peel off from roll web 8 reliably.
The guide reel 32 that the downstream roll web is pushed guide 24 along the direction of the direction that transmits perpendicular to roll web 8 with specific interval, cross the width ground setting of roll web 8, and make the contact area minimum of the front side 8a of every rib and roll web 8.This makes and to stay thereon more difficult the investing on the guide reel 32 of adhesive with on the front side 8a of the roll web 8 of label 7, and by the motion of roll web 8 on guide reel 32, any adhesive that adheres to guide reel 32 is moved to the sunk part 32c on each guide reel 32 every side.
Thus, make the lip-deep adhesive of the guide reel 32 that adheres to contact roll web 8 minimum, and steadily transmit roll web 8.
The guide 29 of front side 8a on the roll web 8 that guide tag 7 adheres to and the stripper roll 22 of the front side 8a that contacts roll web 8 have noncohesive surface.This has prevented to remain in stripper roll 22 and guide 29 that adhesive on the roll web 8 adheres to the front side 8a of contact roll web 8.Roll web 8 transmits reposefully and exports from roll web outlet 4 thus.
Label distributing roller 27 is positioned at the side that feeds out of downstream that label 7 begins to break away from the curved surface 21a at roll web 8 places, label 7.This label distributing roller 27 is driven in rotation along the label emission direction in conjunction with the rotation of stripper roll 22.Therefore, when the fore-end of the label 7 that begins to break away from roll web 8 reached on the label distributing roller 27, along the direction different with the direction of roll web 8, label distributing roller 27 transmitted label 7 to label dispenser opening 3.In case the leading edge of label 7 begins to break away from curved surface 21a place, strip operation can not continue with being interrupted, and the transmission of the combination tag 7 and label guide reel 28 that rotates is directed to label dispenser opening 3 with label 7.Label distributing roller 27 and label guide reel 28 also have non-adhering surfaces.
As mentioned above, label peeling mechanism 20 according to the present invention is pushed at the upstream roll web has many ribs 31 on the guide 23, described rib 31 is along the direction of advancing perpendicular to roll web 8, cross roll web 8 and be formed with the gap therebetween, described rib 31 is the part of the front side 8a of contact roll web 8, thereby makes the contact area minimum with the front side 8a of roll web 8.Therefore, adhesive is then more difficult to the transfer of this contact portion from the front side 8a of roll web 8, and roll web 8 can not have holding paper and other problem ground transmits smoothly.
In addition, by along being provided with a plurality of guide reels 32, can make the downstream roll web push the contact area minimum of guide 24 and the front side 8a of roll web 8 perpendicular to the direction of roll web 8 direction of transfers, the width that crosses roll web with a certain gap therebetween.This also makes from the adhesive of the front side 8a of roll web 8 more difficult to the transfer of this contact portion, and therefore roll web 8 can be transmitted reposefully, and paperboard or other problem can not occur.
Therefore, the label machine 1 with this label peeling mechanism 20 utilizes label peeling mechanism 20, can reliably and fully peel off and discharge Print Label 7 from roll web 8.
In addition, even adhesive adheres on rib 31 or the guide reel 32, adhesive also can be cleared up the conical surface 31b that forms in every side, 32b.In addition, because depression (gap) 31c, 32c also is arranged on the both sides of rib 31 and guide reel 32, and the adhesive that is bonded at rib 31 or guide reel 32 can be moved into these depressions (gap) 31c, 32c, thus eliminate transmitting any influence of roll web 8.
Therefore, can further suppress adhesive and adhere on the surface that contacts roll web 8, and roll web 8 can not have holding paper or other problem ground transmits smoothly.
Non-adhering surfaces also is set on the surface that contacts with the front side 8a of roll web 8, comprises stripper roll 22 and other roller and rib, and the other parts of roll web guide 29.Therefore, make the viscosity minimum of the lip-deep adhesive that contacts with roll web 8, and roll web 8 can be transmitted smoothly, and problem can not be occurred such as holding paper.
This not sticking the processing is not limited to roller and rib, and can be applied to any part of front side (label-side) 8a of contact roll web 8.
As mentioned above, stripper roll 22 and other roller can be made by the silicon rubber with fine anti-adhesion characteristic.
Rib is formed on the upstream roll web that contacts with roll web 8 and pushes guide 23 parts, pushes guide 24 parts and roller is used to contact the downstream roll web of roll web 8.Yet the present invention is not subjected to restriction like this, and rib and roller can be arranged on selectively that the upstream roll web is pushed guide 23 and the downstream roll web is pushed guide 24 according to expecting to have.
Second embodiment
According to a second embodiment of the present invention, below description had another embodiment according to the label machine of label peeling mechanism of the present invention.Like in the label machine 1 of this embodiment and aforementioned first embodiment is represented by similar label, has omitted its further instruction.
At first with reference to Fig. 8 and Fig. 9, description is used for peeling off the label peeling mechanism 20A of Print Label 7 from roll web 8.
The upstream roll web is pushed guide 23A and is set at guiding surface 21c opposite, upstream, and have with specific interval cross that the width of roll web 8 is provided with, as a plurality of guiding surface 23a of the contact site that contacts roll web 8.The downstream roll web is pushed guide 24A and also is arranged on guiding surface 21e opposite, downstream similarly, and have with specific interval cross that the width of roll web 8 is provided with, as a plurality of guiding surface 24a of the contact site that contacts roll web 8.The distance that upstream guide surface 21c and upstream roll web are pushed between the guiding surface 23a of guide 23A is more bigger than the gross thickness of roll web 8 and label 7.Roll web pressing element 26 has convex arcuate (its edge is by the rightabout bending of the direction of roll web curved guide device 21 crooked roll webs), and this pressing element 26 causes this distance to narrow down gradually to the downstream of roll web direction of transfer.As following more detailed description, this has roll web 8 is pressed onto effect on the roll web curved guide device 21 on the upstream side of drive access.
More particularly, near roll web pressing element 26 upstream side at the curved surface 21a of the roll web curved guide device 21 straight line L1 of the center of curvature 25 that connect to determine curved surface 21a and end points 21b is pushed roll web 8; And in the downstream of the curved surface 21a of roll web curved guide device 21, the guiding surface 24a that the downstream roll web is pushed guide 24A exerts pressure to roll web 8 near the straight line L2 that connects the center of curvature 25 and end points 21d.This roll web 8 is pressed against on two points of the upstream side (L1) of curved surface 21a of roll web curved guide device 21 and downstream (L2).This structure can prevent that roll web 8 is outstanding from curved surface 21a, and can transmit roll web 8 through less radius of curvature.When label 7 when the sweep of roll web pressing element 26 is advanced, therefore label 7, and can be peeled off from roll web 8 along the direction bending that breaks away from roll web 8 more reliably by this bending arch section.By roll web pressing element 26 slightly after face side (label-side) bending, roll web 8 is directed into the curved surface 21a of roll web curved guide device 21, and acutangulates bending around curved surface 21a.
From the end points 21b of the curved surface 21a of roll web guide 21, the guiding surface 23a that the upstream roll web is pushed guide 23A along the roll web direction of transfer downstream side extend length-specific.More particularly, guiding surface 23a is from the straight line L1 side extension downstream of the center of curvature 25 of connection end point 21b and definite curved surface 21a.Along the roll web direction of transfer, the downstream roll web is pushed the downstream end points 21d upstream side extension length-specific of the guiding surface 24a of guide 24A from curved surface 21a.More particularly, guide surface 24a is upstream outstanding from the straight line L2 of the connection end point 21d and the center of curvature 25.
In other words, roll web pressing element 26 is pushed guide 23A from the upstream roll web, is set at along a certain position of the upstream of roll web direction of transfer, and causes roll web 8 to be advanced to curved surface 21a, with the face side (label-side) that bends to roll web protrudingly.For making roll web 8 edges and the wherein slightly bending of direction rightabout of the crooked roll web 8 of curved surface 21a, the protrusion arc of roll web pressing element 26 is pushed surperficial 26a and is pushed the guiding surface 23a of guide 23 from the upstream roll web, slightly upstream guiding surface 21c lateral process.Therefore, by roll web pressing element 26 slightly after web surfaces side (label-side) bending, roll web 8 is directed into the curved surface 21a of roll web curved guide device 21, roll web 8 acutangulates bending around curved surface 21a then.
This label distributing roller 27 can be arranged on the downstream with rotating freely, near the curved surface 21a of roll web curved guide device 21.The top of the outer surface of label distributing roller 27 is set in fact the straight line that extends with the guiding surface 23a that pushes guide 23A from the upstream roll web in line.This label guide reel 28 can be arranged on label distribution opening 3 sides and close label distributing roller 27 with rotating freely.Label guide reel 28 and label distributing roller 27 are located in sustained height in fact.And label guide reel 28 and label distributing roller 27 can keep the label of being stripped from.Adopt this structure, because label 7 can separate to discharge from roll web 8 fully, label 7 does not need to utilize the tail end that invests roll web 8 to keep, and label 7 can easily be taken away by the user.
Label distributing roller 27 and label guide reel 28 comprise a plurality of rollers that have certain interval therebetween, cross the coaxial setting of width of label 7, so that 7 on label is touched in a plurality of positions of crossing perpendicular to the tag width of label 7 direction of transfers.This has prevented to adhere to label distributing roller 27 and label guide reel 28 such as the adhesive side owing to label 7, and the user is difficult to remove the problem of label 7 labels.In addition because it is very little to be exposed to the contact area of adhesive side of label 7, also prevented since from the adhesive transfer of the adhesive side of label 7 to and be accumulated on label distributing roller 27 and the label guide reel 28, influence the steady distribution of label 7.
To shown in Figure 11, the label machine 1A of current embodiment also has around the top of roll web outlet 4 to the door assembly 30A of printer open front according to the present invention as Figure 10.The stripper roll 22 of label peeling mechanism 20A, label distributing roller 27, label guide reel 28, power transfer roller 39 and downstream roll web are pushed guide 24A and are attached to this door assembly 30A.
The label peeling operation
The strip operation of the label 7 of this label peeling mechanism 20A below will be described.
Be maintained in the middle of air roll 13 and the printhead 12 when label 7 invests its surperficial roll web 8, transmitted and be printed 12 when printing by air roll 13, specifying information is printed 12 and prints on the surface of blank tag 7.As through the upstream guiding surface 21c of roll web curved guide device 21 and the result between the roll web pressing element 26, roll web 8 transmits to curved surface 21a by slightly after web surfaces side (label-side) bending.Because roll web pressing element 26 makes roll web 8 bend towards its face side (label-side), the roll web 8 with intact label 7 transmits along upstream guiding surface 21c, and the upstream guiding surface 21c that can not rise and leave roll web curved guide device 21.
The upstream roll web is pushed the downstream that guide 23A is positioned at roll web pressing element 26, and the distance between guiding surface 23a and the upstream guiding surface 21c is more bigger than the gross thickness of roll web 8 and label 7.It is also overlapping with the upstream portion of curved surface 21a that the upstream roll web is pushed the guiding surface 23a of guide 23A.Therefore, the roll web 8 with intact label 7 is sent to curved surface 21a along guiding surface 23a, does not leave the guiding surface 23a that the upstream roll web is pushed guide 23A and can not rise.
The downstream roll web is overlapping by guiding surface 24a that pushes guide 24A and curved surface 21a, and therefore, after curved surface 21a bending, roll web 8 can not raise and leave curved surface 21a at roll web 8.Because roll web 8 is bent surperficial 21a and is bent into than small curvature radius, label 7 can be stripped from reliably from chart drum 8.
Label distributing roller 27 be positioned at from label 7 begin to break away from roll web 8 curved surface 21a the downstream label 7 feed out side.This label distributing roller 27 is driven along the label emission direction by power transfer roller 39 with being rotated, and power transfer roller 39 rotates with the roll web interlock that is transmitted.Therefore, when the fore-end of the label 7 that begins to break away from roll web 8 sailed on the label distributing roller 27, label 7 was transmitted to label dispenser opening 3 along the direction different with the direction of roll web 8 by label distributing roller 27.In case the leading edge of label 7 begins at curved surface 21a place to break away from, strip operation can not continue with being interrupted, and label 7 is directed to label dispenser opening 3 by the label guide reel 28 that transmits interlock with label 7 and rotate.
As shown in figure 12, the label 7 that is discharged into label dispenser opening 3 is maintained between label distributing roller 27 and the label guide reel 28, and can be taken away (the same with first embodiment) by the user then.When label 7 is taken away by the user, whether at distribution locations place have detection signal label 7, unshowned sensor trigger printhead 12 and label peeling mechanism 20A print and peel off next label 7, next label 7 then is discharged into distribution locations similarly from label dispenser opening 3 if being used to detect.
As shown in figure 15, when label 53 by the roll web curved guide device 52 of conventional labels mechanism for stripping when roll web 51 is peeled off fully, then after label is peeled off fully, do not have thing to support label.Therefore, small the maintenance that roll web 51 advances to the tail end of label 53 invests the position of roll web 51, thereby keeps label 53, takes away for the user.The weight that remains on the label 53 at its tail end place often causes the front end of label 53 to hang low.When therefore label 53 hangs low, take label 53 away and can become difficult, and label 53 can adhere to the printer casing side.
In addition, if therefore label 53 hangs low, the position of label 53 can change, and detects sensor that peeling label 53 exists to the detection of the label inaccuracy that can become.More specifically, even label 53 is not removed, sensor also may detect does not mistakenly have label, and next label can be distributed mistakenly.For example when label 53 is longer, when label 53 has minimum hardness and be very thin or when wind is arranged, label 53 this hangs low or fall is a problem deserving of attention.
In addition, because the tail end of label 53 keeps investing roll web 51, label 53 is peeled off from roll web 51 by the user, and when use had the adhesive of very high bonding strength, this can be very difficult.
Yet, the mechanism for stripping 20A of the printer 1A of employing current embodiment according to the present invention, when label 7 was discharged into label distribution opening 3 and is positioned distribution locations by label distributing roller 27, the tail end of label 7 was kept by label distributing roller 27, and the mid portion of label 7 is supported by label guide reel 28.Therefore therefore, label 7 is supported on a plurality of positions of tail end and center, and can be held and can not hang down at the distribution locations place.
In addition, even for example owing to wind or other reason, the tail end of label 7 breaks away from label distributing roller 27, and the tail end of label also can contact manual cutter 34, and the middle part of label 7 keeps being supported by label guide reel 28 simultaneously.Therefore, can prevent that label 7 from falling or sagging.
As mentioned above, among the label peeling mechanism 20A that in the label machine 1A of the current embodiment according to the present invention, uses, cross with specific gap therebetween as a plurality of guiding surface 23a of part (rib) of contact roll web 8 roll web 8 width be set to the upstream roll web and push guide 23A, thereby make contact area minimum with the front side 8a of roll web 8.Therefore, can suppress adhesive and transfer to this contact surface, and roll web 8 can not have paperboard and other problem ground transmits smoothly from the front side 8a of roll web 8.
The downstream roll web push guide 24A also have with have therebetween specific interval cross that the width of roll web 8 is provided with, as a plurality of guiding surface 24a of the contact site (rib) that contacts roll web 8, thereby make contact area minimum with the front side 8a of roll web 8.Therefore, can suppress adhesive and transfer to this contact surface, and roll web 8 can not have paperboard and other problem ground transmits smoothly from the front side 8a of roll web 8.
Therefore, utilize label peeling mechanism 20A, can be reliably and fully peel off and distribute Print Label 7 from roll web 8 according to label machine 1A current embodiment of the present invention, that have label peeling mechanism 20A.
In addition, because have the label guide reel 28 that is used to be supported on the label 7 of peeling off and discharging from roll web 8 in roll web curved guide device 21 places according to the label peeling mechanism 20A among the label machine 1A of the present invention, therefore the label of peeling off from roll web 87 can be supported reliably.Therefore, even label 7 is very long or wind is arranged, can prevents reliably that also label 7 is sagging or fall.
In addition, this label peeling mechanism 20A can make Print Label 7 break away from roll webs 8 reliably, and supports the label of having peeled off 7, and eliminates that adhesive side adheres to the problem of printer casing such as peeling label 7 is sagging.
Because the position of peeling label 7 can not change owing to label is sagging, also can be more reliable by the detection that detects the sensor whether peeling label 7 exist.Therefore, though can prevent from reliably not to be removed and problem that next label 7 is assigned with such as last label 7.
As shown in figure 14, can save label distributing roller 27, and label guide reel 28 is positioned the position of label distributing roller 27.
In this case, label guide reel 28 is with distributing labels 7 interlocks and rotate, and label 7 is guided along assign direction.Label 7 transmits to label distribution opening 3, and little the maintenance that arrives the tail end of label 7 invests the position of roll web 8, thereby keeps the tail end of label 7.The middle part of label 7 is supported by label guide reel 28.Therefore, label 7 is supported in a plurality of positions of the tail end of label 7 and center, and therefore can be not supported floppily.
Synthetic plastic such as polyacetal resin can be as the surfacing of label distributing roller 27 and label guide reel 28, but, also can use adhesive to have relative chloroprene rubber roller and combination with silica gel roller of relatively low bond strength than high bond strength with respect to label 7 as selecting.For silicon rubber, very low as the bonding strength of propylene yogurt (acrylic emulsion) glue of label 7 adhesives, thus can prevent that adhesive from adhering on the roller.By using adhesive with respect to label 7, have the roller of a plurality of coaxial settings of different bonding strengths, the combination of roller can be adjusted to provide the confining force of desirable label 7.
Label distributing roller 27 and label guide reel 28 can or be provided with continuously along the series connection of the direction of transfer of label 7, or the width that this roller can cross label 7 alternately is arranged on diverse location.When label 7 was very narrow, staggered roller can make the support of label 7 more reliable.
The roller that is used for being sent to than long peeling label 7 label dispenser opening 3 should not be limited to label distributing roller 27 and label guide reel 28, and three or more these type of rollers can be set.
Though with reference to accompanying drawing also in conjunction with the preferred embodiments, described the present invention, should be noted that: for those skilled in the art, clearly can make various changes and modifications.Within the scope of the present invention that this variation and modification are interpreted as defining in claims, unless they are not in the spirit or scope of the present invention.
