The rollers are rotatably mounted to the carriage, which is mounted to a lead screw that controls the position of the carriage. As the carriage moves across the material, the rollers roll, and the material is cut. The space between the anvil and the blade of at least one of the cutters can be varied to disengage that cutter so that the rolling of the roller will not cut the material. The engagement and disengagement of the cutter is dependent on the position of the carriage.The printer includes a printing mechanism for performing printing operations on a recording medium. A cutting mechanism performs cutting operations on a multi-layer tape. The cutting mechanism has first and second cutting blades. The first cutting blade is arranged to cut through all layers of the multi-layer tape.

Description

Cutter sweep

The present invention relates to a kind of cutter sweep, this cutter sweep is mainly used in the print paper in the PRN device is carried out cutting operation, but does not get rid of other application.

Adopt the electronic printable device of multilayer paper tape to be widely known by the people.This paper tape is installed in the tape cassette, installs in the printer then.The multilayer paper tape comprises figure message printing layer, adhesive layer and back sheet.When a graph text information is imprinted on the printable layer, back sheet is peeled off, then with the figure message printing layer attached to (by utilizing intermediate adhesion layer) on the jobbie.This printing equipment comprises a cutter sweep, from a multilayer paper tape cutting-out part, uses as label when a graph text information prints on the printable layer, by cutter sweep.For this reason, a blade need be installed on cutter sweep, be used for each aspect of paper tape is cut.The cutter sweep of some PRN device also comprises so-called " hemisection " (tab cut) blade.This blade only cuts some aspects (figure message printing layer or back sheet) of multilayer paper tape, and does not cut remaining aspect.For example, use a kind of hemisection blade in a kind of machine of applicant's produce and market of the present invention (model is DYMO 6000), it only receives (printing) layer to top picture and text and cuts, and does not remove to bump back sheet.This blade is easy to make figure message printing layer and back sheet to be separated.

In DYMO 6000 machines, the hemisection blade of employing is a ceramic tip, it is positioned in the hemisection blade cartridge by a blade mould, exposes outer about 100 microns of box.When carrying out the hemisection operation, the figure message printing layer on the paper tape is cut by the motive force that acts on the blade cartridge.In this whole process, paper tape is supported by the surface of a flat anvil.Protrude in the outer part of box by blade and control accurately, can guarantee that blade only cuts the picture and text layer in the hemisection process, and not cut back sheet.

There is such problem in such scheme: when the paper tape that will cut during than broad, blade cartridge needs very big active force.The normally used tape width of this PRN device is 6 millimeters, 12 millimeters or 19 millimeters.If the paper tape to 19 mm wides carries out hemisection, needs 80-100 newton's dynamics.This is difficult to accomplish for small print equipment.

We are described a kind of cutter sweep that can overcome above-mentioned difficulties in a unsettled European application (European patent application publication No. 0711637).This pending application is disclosed after the application's priority date.Here the content in the pending application is quoted.A mobile anvil sheet is housed on the cutter sweep of describing in pending application, and be used to carry out and the related rolling of blade: when cutting, the anvil sheet moves downward, and promotes blade and little by little paper tape is cut.In other words, because low tape is finished cutting in moment, needed motive force is much smaller naturally.

In EP 0711637 application, described rolling anvil sheet is used for carrying out the hemisection operation, cut full operation by another independently cutting mechanism finish, this mechanism mechanically is connected with above-mentioned rolling anvil sheet.The invention provides a kind of improved plan.

According to an aspect of the present invention, a kind of cutter sweep that the multi-ply paper band is cut of being used for is provided, this device comprises: two cutting blades, wherein first blade is used for each layer of multilayer paper tape cut, second blade is used for the some of multilayer paper tape or some aspects are cut, do not cut but keep all the other at least one aspects, second blade is positioned on the longitudinally of paper tape, interrelates with first blade; And an anvil sheet fulcrum, it " is shouldered " and two anvil sheets, matches with described two blades respectively, and anvil sheet fulcrum can roll, and when it does laterally to roll on paper tape, drives blade paper tape is cut.

Described first blade and second blade can be installed in the same blade cartridge.

So we provide a kind of simple cutter sweep that can cut entirely with two kinds of operations of hemisection on a multilayer paper tape.This cutter sweep is particularly useful for foregoing printing equipment.Therefore, the present invention also provides a kind of printing equipment that utilizes above-mentioned cutter sweep.This printing equipment can comprise a keyboard or other similar input unit, is used to import information defined by the user, such as printable character, tag length, tag format, or the like.This printing equipment also comprises a kind of printing mechanism that contains a printhead and impression dish, to carry out printing.In one type printing equipment, a figure message printing paper tape and a heat conduction colour band are overlapping and are passing through printing mechanism.Figure message printing paper can promote with an impression disk drive motor, also can drive with one group of feed rollers, makes it pass through print point.This printing equipment has a microprocessor controller, is used for printing time control according to the data of importing by input unit with the user that move of paper tape.One row type element is arranged on the thermal printer head, graph text information is printed on the paper tape by the hurdle when guaranteeing that paper tape is by printing mechanism.

In this class printing equipment, the common practice is that the content to label defines and prints, then with the whole cutting-out of the part of printed label on the paper tape.

We also can utilize a kind of cutting mechanism, as long as on the position of a determining deviation of paper tape longitudinally, carry out hemisection, with the border of definition label, just these hemisection labels can be torn from back sheet then, and will not cut a part by whole multilayer paper tape.This scheme is described in one embodiment of the invention.It is to realize by a device that the generation of first blade is broken away from of installing in cutting mechanism.The distance that can utilize anvil sheet fulcrum to move that selectively breaks away from of first blade is controlled.

The periphery of each piece anvil sheet preferably has the slit one, aims at the blade that it cooperated respectively, directly touches to avoid blade and anvil sheet surface.This has following benefit:

Avoid directly touching between blade and the anvil sheet can avoid the blade damaged;

Blade protrudes in the outer part of box and needn't resemble and control accurately the former scheme, and this helps reducing the requirement of blade at manufacture view.

If above-mentioned this slit can be provided, so, the difference of hemisection blade and full cutting edge just only is length different of blade exposed portions serve from box.Like this, hemisection blade and full cutting edge just can shared blade cartridges.

According to another aspect of the present invention, provide a kind of the multi-ply paper band is carried out the cutter sweep of cutting operation, this cutter sweep comprises: a guider, stretch basic and paper tape face keeping parallelism along the horizontal cross direction of paper tape; A cutter unit is done transverse movement, to cause cutting operation on paper tape under the guiding of guider.

The motion of rotation anvil sheet 38 promotes cutting body actuating guide rod and moves in the guide rail 50 of cutting body 20.This further drives cutting body 20 and moves toward the figure right side.The cutting body actuator lever moving spur backspring 8 simultaneously to calling in the following text, make it in tension.When cutting body 20 is shifted to right side shown in Figure 2, drive blade 22 at the first cutting position C ₁Paper tape is cut entirely.

Fig. 3 represents a kind of cutter sweep according to an embodiment of the invention.This cutter sweep is at can not providing a paper tape supporting wall that resembles slit 24 when a tape cassette (shown among Fig. 1 14), but at the downstream position (in certain guiding area) of print point just the situation of stand.Device is whole is positioned at outside the tape cassette border in a cutting in this case, and tape cassette needn't figure message printing paper and heat conduction colour band with fashionable dress.Heat conduction colour band can be contained in another box, perhaps does evening not.

Fig. 4 A and 4B are illustrated this.Among Fig. 4 B, for simplicity's sake, the chassis of printing equipment is omitted.But, should be understood that tape cassette is that the tape cassette of delivering to printing equipment is received in the platform and gone.Printing equipment comprises a printing mechanism.It is made of printhead 210 and impression dish 212, is similar to foregoing example.Fig. 4 represents an ink ribbon cartridge 214, the inside dress inking band or heat conduction colour band; Also have basic unit's tape drum 216, the figure message printing paper tape is being adorned in the inside.Figure message printing paper and China ink band overlap the to each other by the space between printhead 210 and the impression dish 212, print operation.After having printed, China ink band is brought back in the ink ribbon cartridge 214, and figure message printing paper is then delivered to the left side shown in Fig. 4 B from print zone, and this is that rotation by impression dish 212 drives.Substrate tape drum 216.At EL place, paper tape outlet position one leader 218 is arranged.(EL) downstream has a cutting device 220, back will describe this device in detail in the exit position.Fig. 4 draws the side view of Fig. 4 B along arrow IV direction.Among Fig. 4 A, can see the chassis 222 of printing mechanism.It is used to support black tep reel 214 and basic unit to be with to surplus 216.In addition, the observer of Fig. 4 A also can see paper tape T.Now cutting mechanism 220 is described in detail.Please see Figure 3, wherein cutter sweep has a blade cartridge 100, and there is a full cutting edge 102 the inside, is used for each aspect of multilayer paper tape is cut; Also have a hemisection blade 103, be used for a part of aspect of paper tape is cut, do not cut and stay bottom (back sheet).This cutter sweep also comprises an anvil sheet fulcrum 104, and it is being with two " rolling anvil sheets ": wherein the first anvil sheet 106 cooperates with full cutting edge 102, and the second anvil sheet 108 cooperates with hemisection blade 103.Anvil sheet fulcrum 104 is taked the central shaft shape.Can rotate around the A-A axle.Have the periphery of an anvil sheet that narrow slit is all arranged one, they are respectively 106a and 108a.

Each road " slit " all with its alignment blade, in order to avoid blade directly touches mutually with the anvil sheet.Among Fig. 3, paper tape T delivers in the cutter sweep along the arrow B direction from tape cassette.Cutter sweep C ₁And C ₂Separately.Be similar to the situation among Fig. 1, purpose is at C ₁Cut full the position, at C ₂Hemisection is carried out in the position.The back will further describe this.

Fig. 5 A is the end-view of above-mentioned cutter sweep.It is along observing from the direction of the paper tape T in the tape cassette, can seeing a part and the full cutting edge 102 of blade cartridge 100 thus.Among Fig. 5 A, the width of paper tape T is defined as W.The value of W is not single constant, and it depends on the width of the paper tape of actual input.

Anvil sheet fulcrum 104 is positioned on the slide block 110.Under the effect of spring 112, keep constant, downward active force between anvil sheet fulcrum and the blade cartridge 100, represent with F.Slide block can laterally move back and forth at the effect lower edge paper tape of the motor that is driven by driving screw 114.Along with the motion of slide block, thereby anvil

sheet

106 and 108 is ensued to rotate and is driven two blades respectively at cutter sweep C ₁And C ₂T cuts to paper tape.

Fig. 5 B is the cutaway view of slide block 110.This figure has clearly illustrated that the operation principle of slide block more.Driving screw 114 passes a round hole 115 in the middle of the slide block 110, and tightly clamp driving screw with nut in the exit, two ends in the hole.Like this, the lift-over of driving screw just can drive slide block 110, makes tool do translational motion by direction shown in Fig. 5 B.

Slide block 110 comprises a main part 110a and a hinge portions 110b.One place's recess 119 is arranged on the hinge portions 110b, be used for " stinging " live anvil sheet fulcrum 104.Hinge portions 110b links to each other with main part 110a by twisting point 110c.Spring 112 is between main part 110a and the hinge portions 110b.The stretching motion of spring 112 produces above (in conjunction with Fig. 5 A) said downward power F.

For the ease of the making of slide block, can be during making with main part 110a and hinge portions 110b as a whole, shown in Fig. 5 C.In manufacturing process, spring can be pacified into wherein, then with hinge portions 110b by shown in arrow Y direction amount to, thereby can simplify manufacturing process.

In another embodiment of the present invention, full cutting edge can take place to link or break away from cutting mechanism selectively, finishes the task of cutting entirely thereby allow cutter sweep to utilize hemisection to operate, and perhaps only carries out the hemisection operation.Fig. 6 has shown a kind of like this cutter sweep.It and Fig. 3 are somewhat similar, and two

anvil sheets

106 and 108 are wherein arranged, and all are enclosed within on the pillar 104.Full cutting edge 102 is positioned on the blade guide plate 116, and guide plate 116 is by door bolt plate 118 brakings.Door bolt plate 118 is smooth substantially, and it comprises a part that is elongated, and is movable in gathering sill 120.Gathering sill 120 is positioned at blade cartridge 100.Fig. 7 A is the end-view of this cutter sweep, and it has been illustrated more clearly in the situation of door bolt plate.Among the figure, the door bolt plate is in the position of withdrawal.The right hand one side of door bolt plate comprises a convex part 122, and it is connected with blade guide plate 116.The left-hand side of door bolt plate 118 comprises an actuation part 124, and it is elongated part upwards uprightly from the door bolt plate.Actuation part 124 is carrying a brake bar 126, stretches along blade cartridge longitudinally (being the direction that slide block 110 moves), and a stopping part 128 is arranged on its top.Arrange by following mode the position of stopping part 128.

Fig. 7 A represents that anvil sheet fulcrum 104 is in origin position, promptly is arranged in the figure high order end.In this position, fulcrum 104 withstands the brake portion 124 of door bolt plate 118, thereby makes convex part 122 withstand the guide plate 116 of cutting blade downwards, and full cutting edge 102 is broken away from.When anvil sheet fulcrum 104 from the source point position when the arrow C direction is rolled to the right side of Fig. 7 A, only paper tape is carried out hemisection.Anvil sheet fulcrum 104 has two final positions, is respectively the outer terminal point shown in the interior terminal point shown in Fig. 7 B and Fig. 7 C.In interior final position, the axle body of expression fulcrum is the stop end 128 of close brake bar 126 just, thereby can not cause fastening with a bolt or latch moving of plate 118.At this moment, full cutting edge still is in disengaged position.Therefore, when anvil sheet fulcrum reversing stroke when interior terminal point is got back to origin position, do not do entirely and cut.

If anvil sheet fulcrum 104 is rolled into the outer final position shown in Fig. 7 C, represent that then fulcrum has knocked the stop end 128 of brake bar 126, move right thereby drive door bolt plate 118.At this moment, convex part 122 discharges blade guide plate 116, makes full cutting edge get back to its cutting position again.So, in the stroke that reverses of fulcrum 104, finish paper tape cut operation entirely.Carry out when once cutting operation entirely, the brake portion 124 that anvil sheet fulcrum 104 will be fastened plate 118 with a bolt or latch in the final stage of its stroke that reverses pushes back left, gets back to origin position up to fulcrum.At this moment, door bolt plate 118 promotes cutting blade guide plate 116 by its convex part 122 and moves down, thereby makes full cutting edge 102 enter the off-position state.Consequently, operation in the dynamic stroke, does not take place to cut entirely in anvil sheet fulcrum 104 outside the next one.In other words, present embodiment only allows to cut entirely to operate and occurs in the stroke that reverses of anvil sheet fulcrum 104.

Fig. 8 represents initial point (starting point), interior terminal point terminal point difference residing position (they all exceed the width range of paper tape T) outside.It is to cut entirely simultaneously and hemisection that this situation allows the user to select, and still only does hemisection.This point can realize automatically by scheme shown in Figure 9.The blade cartridge that do not draw among Fig. 9, but drawn slide block 110 and rotation anvil sheet 106.As described in preceding (in conjunction with Fig. 5 A), slide block 110 slides on a driving screw 114.The numeral 200 the expression dc motors, be used to drive driving screw, make its by gear reduction to 202.First leaf switch 204 is used to judge the origin position of anvil sheet fulcrum 104.The interior terminal point of fulcrum 104 and the judgement in outer final position by another (second) sheet switch 206 by gear reduction is carried out the detection of 202 second gear revolutions.The detection of the second gear revolution can by (such as) one realize with the contacted edge cam of second gear surface.Like this, the rotation first time corresponding to driving screw 114 will produce a pulse at second leaf switch 206 place, can produce a coding that simply increases progressively thus.Figure 10 has represented the signal from

leaf switch

204 and 206 respectively.Claim in this document that

leaf switch

204 and 206 is " a diagnosis switch ".

Figure 11 is the block diagram of circuit that is used to realize the printing equipment of These characteristics.Wherein, a central controller 300 is arranged, it comprises a microprocessor, ROM 302 and RAM 304.Controller 300 is connected with a liquid crystal display (LCD) driver 309.LCD driver 309 is used to drive the display 308 of this printing equipment.Thick line between controller 300 and the lcd driver 309 represents that display and driver thereof can be placed on the place away from printing equipment.Controller 300 also is connected with a keyboard (or similar input unit) 306, with relevant data messages of operation such as reception and printing, cuttings.For this reason, the invention provides a plurality of keys, for example key 310,320,312,316, or the like.Thick line between controller 300 and the keyboard 306 represents that keyboard can be away from printing equipment.Controller is also connected on printhead 210 and the paper tape drive unit 307.Drive unit 307 is used to drive the impression dish paper tape is sent printing equipment.Printhead and paper tape drive unit one are used to start and print and the paper feeding operation.These operations are all carried out under the management of controller.Controller 300 also links to each other with a reversing motor control circuit 317.This circuit is controlled the operation of cutting blade CD-ROM drive motor 200 in the following manner.

The signal that controller 300 receives from cutting blade diagnosis switch 204 and 206 (as shown in Figure 9).Controller 300 also is connected with tape cassette diagnosis switch 301.The tape cassette that diagnosis switch 301 is positioned at printing equipment is received branch, be used for parameter (such as the character of paper tape, width etc.) to relevant paper tape discern, confirm, to offer controller 300.

Now the operation of control circuit is described in conjunction with Figure 12.The effect of control circuit 300 is to realize foregoing function.That is to say, be used for the signal that cutting blade diagnoses switch 204 and 206 places to transmit is received.Judge the position at slide block place thus, then, terminal point or outer final position make the direction of motion reversing of anvil sheet fulcrum in being chosen in.

Among Figure 12, step 400 has more specifically been pointed out the beginning of cutting operation.The cutting key need only be the user on keyboard 306, clicked and just cutting operation can be started.Also can utilize machine this automatically starts cutting process behind the label of having printed a regular length.Is in step 402, controller asked: need to cut entirely? this can only be made one's options when label being formatd or start cutting operation by the user.According to the difference of answering, and different N values is arranged.The value of N equals to diagnose the number of the coded pulse that switch 206 places transmit.If need cut entirely, N=N then ₂If only carry out hemisection, then N=N ₁Obviously, N ₁Should be less than N ₂This is because the outer dynamic stroke displacement of slide block 110 when only carrying out hemisection is littler than its stroke displacement of reversing when cutting entirely.

In step 404,, slide block 110 is outwards moved by hotwire 200.Diagnosis switch 204 judges that when slide block is by origin position (shown among Figure 10 405)." transition " shown in 405 detects in step 406, by controller the incremental coded pulse signal that comes self-diagnostic switch 206 counted then.Number (the N that equals to be scheduled to as N ₁Or N ₂, set at step 403a and 403b respectively) time, the direction of motor is reversed in 407 steps, thereby sliding shoe 110 is slided along the backhaul direction.When the initial point signal was received (408 step), process finished (409 step).When anvil sheet fulcrum 104 arrived origin position, diagnosis switch 204 (see figure 9)s were closed DC motor 200.This operation is to finish by the software ground connection in the controller 300.Like this, the user just can cut or not with the label of cutting operation entirely entirely by a printer user interface setting band.And, can also produce a string totally 20 labels.In the end after label, controller is carried out by the last hemisection of cutter sweep utilization and is once cut entirely, so that this a string label leaves printing equipment.In our earlier application (European Application Publication number) 0578372, can produce the method that so-called string trimscript signs and be described in detail this.Here this is quoted.

The production process of flow chart shown in Figure 13 a string in order to illustrate (20) label, this process is at last by once cutting EO entirely.The requirement that begins to propose a string about producing (P altogether) label of flow chart for the user.All labels all are on same the background paper tape in the string, are only severed by a hemisection each other.Represent with 500 steps among the figure.

Before printing first label, processor P value earlier is set to 0 (502 step), begins to print first label (504 step) then.In 506 steps, the value of P adds 1, and in 507 steps, this value and P compare.Obviously, after having printed first label, the two is never equal, so full cutting edge breaks away from as previously mentioned.This means in 510 steps and only carry out the hemisection operation.

When P=P, full cutting edge returns to the operating position, so next time, just in the end do in the hemisection this label string once to be cut entirely on a label.Shown in 512 steps.

The process that the flowchart text user of Figure 14 makes one's options to options at user interface.Describe in detail in application " printing equipment " (No. 80374-slug of PWF " 6500 interfaces-key and display ") of also determining as us, printing equipment has a user interface, comprises a display and various enter key.These enter keies comprise: " printing " key, options button of one group of function key and one group of data entry key.Function key comprises that one is provided with key and a special keys, is used for the various cutting operations of discussing are herein selected (being made by the user).The user is by selecting printing by printing key, shown in 600 steps.Click " special keys " and a label choice menus (as shown in figure 15) on display screen, will occur.The user can utilize cursor (directionkeys) to choose one of the following option:

Umber

Company's umber (inc.copies)

Color

Browse in advance before the printing

Conversion

Series

The user also can be in showing square frame 601 utilizes data entry key to import a number, and these data will appear at above-mentioned selected option next door.Processor then judges whether to select " many parts " in 602 steps.If have only a label, then carry out 604 steps, Print Label is finished a hemisection and is once cut operation entirely in 606 steps then.

The user need only click the function key of these settings, choice menus as shown in figure 16 will occur, and two kinds of cutting options are wherein arranged:

Only do hemisection (Tab Only)

Section (Cut Tab)

Judge whether the user has selected " only doing hemisection " one in 608 step processor.If what choose is to cut operation entirely, then in 610,612 and 614 these series of steps, will prints some parts of labels, and they will be cut one by one entirely.

If what select is " only doing hemisection ", then enter the program shown in Figure 13 (corresponding to 616 steps among Figure 14).

When carried out be once " string is cut " rather than " cutting entirely " time, processor will need the leads length of label is carried out some adjustment.This can carry out with the method for explanation described in EP 578372 applications.

Once mentioned as top, the user can select many parts of the same form to same label.Printing equipment can be counted and shows according to user's needs umber.Content displayed comprises the unprinted umber of having printed of umber Buddhist monk.In addition, also printing equipment can be arranged to " increasing progressively umber " form, that is to say that printing equipment can be printed some parts of labels, wherein all be printed on a sequence number on every part of label, the sequence number of a label in back is than preceding a increase by 1.Perhaps, the user can also be the selected identical sequence number of printing of some parts of (such as 3 parts) labels.

In addition, can also utilize following way to shorten the leads length of label: when label begins to print to half, to answer length by the mark of importing a setting printing is ended, then carry out a hemisection, continue label printing intact then.This way can shorten the length of the label of generation, thereby saves print paper.
