Description
Technical field
The present invention relates to a kind of printing machine with thermal excitation device of temperature-sensitive pasted paper, this paper for example can be used as adhesive label, wherein on a surface of sheet form base, formed the temperature-sensitive adhesive layer, though the temperature-sensitive adhesive layer does not possess adhesive capacity under normal state, yet it can produce adhesive attraction by heating, and the present invention relates to forwarding of a kind of paper and cutting method particularly.
Background technology
At present, mainly adopt adhesive label at aspects such as show bar font code, price lists, this label forms pressure-sensitive adhesive layer by the back side at label recording surface (printing surface) and temporarily adhere to separator on above-mentioned layer and makes to produce fixation.Yet, in such adhesive label, when used as label, separator must be stripped down from pressure-sensitive adhesive layer, this just can't be avoided producing the shortcoming of refuse.
Therefore, as a kind of method that does not need separator, developed the bonding label of a kind of temperature-sensitive, it has: be positioned at the temperature-sensitive adhesive layer on the back side of sheet form base, though this layer does not possess adhesive capacity under normal state, yet has adhesive capacity when being heated; And the thermal excitation device, it is used to heat temperature-sensitive adhesive layer on the above-mentioned label back side so that it possesses adhesive capacity.
For example, the thermal excitation device has adopted multiple heating means, and it adopts warm-up mill, hot air heater, infrared radiation, electric heater, medium coil etc. as heater.In addition, a kind of technology that heats the temperature-sensitive adhesive layer when the bonding label of a head and temperature-sensitive is contacted is for example disclosed in JP-A-1999-79152, this head has on the ceramic bases of being arranged on and as a plurality of resistive elements (heating element heater) of thermal source, as the hot first sample as the print head of thermal printer.
Introduce the universal architecture of the conventional presses that is used for the temperature-sensitive pasted paper below with reference to the thermal printer P2 among Figure 15.
Thermal printer P2 shown in Figure 15 comprises: drum shell unit 20, and it is used for the bonding label 60 of bar shaped temperature-sensitive that clamping is wound into the cylinder shape; Be used for the printing element 30 that on the bonding label 60 of temperature-sensitive, prints; Be used for cutting unit 40 with what temperature-sensitive pasted paper 60 cut into label with predetermined length; And thermal excitation unit 50, it can be used as the temperature-sensitive adhesive layer that the thermal excitation device comes the bonding label 60 of thermal excitation temperature-sensitive.
The bonding label 60 of temperature-sensitive has such structure, promptly for example is formed with insulating barrier and temperature-sensitive dyed layer (printed layers) on the end face of sheet form base, and has formed the temperature-sensitive adhesive layer of the heat sensitive adhesive that has coated and dry on its back side.
Cut the bonding label 60 of temperature-sensitive that unit 40 is used for being printed by printing element 30 and cut into suitable length, it comprises by the operated movable scraper 41 of drive source (not shown) such as motor and is fixed on fixed doctor 42 on the side relative with movable scraper, or the like.
When in the bonding label of temperature-sensitive is forwarding, unclamping, label is understood wrinkling or is blocked continually in transmission, therefore, the speed that forwards (print speed printing speed) of printing platen 33 is fixed under the speed identical with the speed that forwards (excitation rate) of the platen 53 that is used for thermal excitation usually.
According to the thermal printer P2 of such structure, after the adhesive capacity of the bonding label 60 of temperature-sensitive formed, display label, price tag or advertisement tag just can adhere on cardboard, packaging for foodstuff, vial, the plastic housing etc. same as before.Therefore, used separator just becomes unnecessaryly on traditional general adhesive label, thereby has reduced cost effectively.From economizing on resources and the viewpoint of environmental protection, because without any need for the separator that after use, can become waste product, so it is favourable.
Yet in printing machine P2 as shown in figure 15, carry out when cutting operation, in the time period (for example being 0.4 second) that movable scraper 41 is in vertical motion, must stop to forward of the bonding label 60 of temperature-sensitive when cutting unit 40.That is, cut unit 40 in printing platen 33, draw rollers 54 be used for carrying out under the state that the platen 53 of thermal excitation stops the rotation and cut operation.
Therefore, when tag length greater than from cut unit 40 cut the position to the heating element heater 51 of the heat that is used for thermal excitation 52 apart from the time, forward in that bonding label 60 is clamped under heat 52 that is used for thermal excitation and the state between the platen 53 that is used for thermal excitation and stops with temperature-sensitive.
As a result, the temperature-sensitive adhesive layer with adhesive can stick to heat 52 (heating element heater 51) that are used for thermal excitation, can't forward label smoothly even recover to forward also, has therefore brought for example so-called paperboard or has forwarded the shortcoming of fault.In addition, also exist from the heat of heating element heater 51 in addition can be delivered to the bonding label of temperature-sensitive with the problem on the painted printed layers (temperature-sensitive dyed layer).
In this case, if discharge label, because the outward appearance of label is ugly, it can't be used as adhesive label so.In addition, if label clings regularly, the operation that stops printing machine so possibly is to keep in repair.Therefore, printing machine P2 shown in Figure 15 is existing defective aspect the production efficiency that improves adhesive label.
Summary of the invention
An object of the present invention is to provide a kind of forwarding and cutting method and a kind of printing machine, it can cut into the temperature-sensitive pasted paper predetermined length, is sandwiched in the heater that is used for thermal excitation and is arranged under the state between the platen on the side relative with heater at the temperature-sensitive pasted paper to need not to stop to forward of paper.
The present invention is the forwarding and cutting method of temperature-sensitive pasted paper in the printing machine, printing machine comprises: printing equipment, it has be used for the printing mechanism of printing on the printed layers of temperature-sensitive pasted paper, the temperature-sensitive pasted paper is by the lip-deep printed layers that is formed on sheet form base and be formed on another lip-deep temperature-sensitive adhesive layer and form, printing equipment also has first and forwards device, is used for forwarding the temperature-sensitive pasted paper along predetermined direction; Be arranged on printing equipment cutting means afterwards, be used for the temperature-sensitive pasted paper is cut into predetermined length; And thermal excitation device, it comprise be arranged on after the cutting means be used to heat the heater of temperature-sensitive adhesive layer and be used for forwarding second of temperature-sensitive pasted paper along predetermined direction forward device, in described method, forward the speed control of device and after paper temporarily unclamped between cutting means and thermal excitation device, stop first and forward the operation of device forwarding device and second so that cut paper with cutting means according to first.
Here, when cutting means cut paper, the provisional yardage that unclamps was greater than forwarding the yardage that device forwards by second.For example, when second speed that forwards that forwards device (being used for the platen and the draw rollers of thermal excitation) is when time of cutting of 100 mm/second and cutting means being 0.4 second, because second forwards the paper that device has forwarded 40 millimeters in 0.4 second process, therefore the paper that is unclamped is 40 millimeters and longer.
Therefore, since the temperature-sensitive pasted paper can be when forwarding device and forward or before the front end of temperature-sensitive pasted paper arrives the heater place by second cropped cutting device, for example just can solve paper because of the jammed shortcoming of the adhesion of temperature-sensitive pasted paper and heater, and need not to carry out unworthy maintenance, for example take out the label that causes paperboard.Therefore, can greatly improve the production efficiency of adhesive label.
More particularly, be lower than first speed that forwards that forwards device, can between cutting means and thermal excitation device, temporarily unclamp the paper of predetermined length by making second speed that forwards that forwards device.Up to now, though generally forwards the temperature-sensitive pasted paper and it is unclamped, yet that the present invention specially makes first speed that forwards (print speed printing speed) and second that forwards device forward the speed that forwards (excitation rate) of device is mutually different by making first speed that forwards that forwards device equal second speed that forwards that forwards device.Like this, can freely unclamp the temperature-sensitive pasted paper of predetermined length.
Forward device when being arranged to the platen that be used for thermal excitation relative and forming when second, between cutting means and thermal excitation device, temporarily unclamp the paper of predetermined length according to the first speed control that forwards device and be used for the platen of thermal excitation with heater.When before platen, being provided with a pair of draw rollers that is in contact with one another, can forwarding the speed control of device and draw rollers and between cutting means and thermal excitation device, temporarily unclamp the paper of predetermined length according to first.Therefore, the temperature-sensitive pasted paper can freely unclamp and control without any need for the speed of complexity.
By when the front end of temperature-sensitive pasted paper arrives draw rollers and be used for space between the platen of thermal excitation, stopping the rotation of draw rollers, just can between cutting means and thermal excitation device, temporarily unclamp the paper of predetermined length at every turn.Therefore, the temperature-sensitive pasted paper can freely unclamp and control without any need for the speed of complexity.
Printing machine according to the present invention is a kind ofly can realize the above-mentioned printing machine that cuts and forward method that is used for the temperature-sensitive pasted paper, it comprises at least: printing equipment, it has the printing mechanism that can print on the printed layers of temperature-sensitive pasted paper, the temperature-sensitive pasted paper is by the lip-deep printed layers that is formed on sheet form base and be formed on another lip-deep temperature-sensitive adhesive layer and form, printing equipment also has first and forwards device, is used for forwarding the temperature-sensitive pasted paper along predetermined direction; Be arranged on printing equipment cutting means afterwards, be used for the temperature-sensitive pasted paper is cut into predetermined length; The thermal excitation device, it comprise be arranged on after the cutting means be used to heat the heater of temperature-sensitive adhesive layer and be used for forwarding second of temperature-sensitive pasted paper along predetermined direction forward device; And can control first individually and forward the controller that device and second forwards the speed that forwards of device, what printing machine also comprised space with the temperature-sensitive pasted paper that can unclamp predetermined length between cutting means and thermal excitation device deposits paper part and the paper guide that is used for unclamping along predetermined direction the temperature-sensitive pasted paper.
Therefore, depositing paper part by setting can prevent to forward fault because of what the entanglement of unclamping paper caused.
Specifically, paper guide is by parallel first guide of the temperature-sensitive pasted paper of being arranged to basically and forwarding and be arranged in second relative with first guide on the temperature-sensitive pasted paper that the forwards guide and form, and second guide is provided with and is used to help the temperature-sensitive pasted paper depositing the targeting part that paper unclamps in partly.For example, first guide can be arranged on the plate shape guide on the passage from cutting means to the thermal excitation device, second guide can be a pair of and basically meet at right angles ground crooked guide relative with first guide, and they can be arranged in the insertion portion of the release portion of cutting means and thermal excitation device.Like this, owing to can prevent from paper is applied bigger stress, therefore can prevent that paper is wrinkling because of laxity, paper one unclamps in depositing the paper part surely.Being formed on open section between a pair of guide (second guide) can be used as and deposit the paper part.
Paper guide can comprise the release direction modifier that is used to specify the direction that paper discharges from printing equipment, and is used to specify the direction of insertion modifier that paper is inserted into the direction in the thermal excitation device.Therefore, need not to be provided with guide just can unclamp paper on required direction to a certain extent.
When printing mechanism is that to be used for forwarding device by the printing heat head and first that the printed layers of heating temperature-sensitive pasted paper is printed be when being arranged to the printing platen relative with the printing heat head, the release direction modifier is formed by printing heat head and printing platen, and the printing heat head is arranged so that with the printing platen tangent line of the tie point that passes through the two is inclined to predetermined angle with the straight line of the insertion point of point of release that is connected printing equipment and thermal excitation device.
For example, (deposit paper and partly be arranged on the top that forwards direction) when second guide is open upwards, the printing heat head is arranged so that with the printing platen tangent line of the tie point that passes through the two is inclined to 0 to 90 ° with the straight line of the insertion point of point of release that is connected printing equipment and thermal excitation device.Therefore, unnecessaryly a new part is set is used as the release direction modifier, thus the size that can prevent to increase the manufacturing cost of printing machine and increase equipment.
When heater is the hot head that is used for thermal excitation that can come the above-mentioned layer of thermal excitation by the temperature-sensitive adhesive layer of heating temperature-sensitive pasted paper, and second forward device be arranged to relative with the heat that is used for thermal excitation when being used for the platen of thermal excitation, the direction of insertion modifier is formed by heat head that is used for thermal excitation and the platen that is used for thermal excitation, and the heat head that is used for thermal excitation and the platen that is used for thermal excitation are arranged so that the two the tangent line of tie point of process is inclined to predetermined angle with the straight line of the insertion point of point of release that is connected printing equipment and thermal excitation device.For example, when second guide was upwards opened, the heat head that is used for thermal excitation was arranged so that with the platen that is used for thermal excitation the tangential direction and the horizontal direction at their contact point place are inclined to 0 to 90 °.A new part is set is used as the direction of insertion modifier with regard to unnecessary like this, thus the size that can prevent to increase the manufacturing cost of printing machine and increase equipment.
When a pair of draw rollers that is in contact with one another that second forwards in the paper insertion portion that device is arranged on the thermal excitation device, the direction of insertion modifier can be formed by a pair of draw rollers, and a pair of draw rollers can be arranged so that the tangent line through the two tie point is inclined to predetermined angle with the straight line of the insertion point of point of release that is connected printing equipment and thermal excitation device.
In addition, preferably with can change mutual spacing from mode form printing equipment, cutting means and thermal excitation device.Up to now, because the fixed-site of each device, the cropped one-tenth of paper is the shortest length of (draw rollers) from cutting means to the thermal excitation device.Yet according to said structure, can produce short paper, and it is cut into required length.
In this case, for example, pilot unit such as guide rail can be arranged on forwarding on the direction of temperature-sensitive pasted paper, make cutting means and thermal excitation device to slide forwarding on the direction of paper, thereby regulate mutual distance.In addition, can be by forming cutting means with movable manner in vertical direction and the thermal excitation device is regulated mutual distance.

Introduce below with reference to Fig. 5 to 14 and to be used for the control method of unclamping the speed that forwards of the bonding label of temperature-sensitive between unit 40 and the thermal excitation unit 50 cutting.
In this embodiment, distance from printing platen 33 (printing heat head 32) to movable scraper 41 is 10 millimeters, distance from movable scraper 41 to draw rollers 54 is 30 millimeters, and the distance of (heat 52 that is used for thermal excitation) is 10 millimeters from draw rollers 54 to the platen 53 that is used for thermal excitation.The driving time that being used to of movable scraper 41 cuts a label is 0.4 second, and tag length is 200 millimeters.
The speed that forwards (print speed printing speed) of printing platen 33 can be changed to 200 mm/second or 100 mm/second, consider the thermal excitation time of temperature-sensitive adhesive layer, be used for the speed that forwards (excitation rate) stuck-at-00 mm/second of the platen 53 of thermal excitation.The speed that forwards of draw rollers 54 can be changed to one of them of 100 mm/second, 20 mm/second and 5 mm/second.
First embodiment of method for control speed is a kind of like this control method, and it unclamps label by the rotation that stops draw rollers 54 in thermal printer P1 when the front end of the bonding label 60 of temperature-sensitive arrives draw rollers 54 and be used between the platen 53 of thermal excitation.Fig. 5 is the view that is used to describe the state that forwards of the bonding label 60 of temperature-sensitive, and Fig. 6 is the time diagram of driving condition that has shown printing platen 33, movable scraper 41, draw rollers 54 and be used for the platen 53 of thermal excitation.The label a at the place, top of the time diagram of Fig. 6 is corresponding to (g) with each state (a) of Fig. 5 to g.
According to the rotation of printing platen 53, the bonding label 60 of temperature-sensitive stretches with the speed of 100 mm/second, and prints on printed layers (temperature-sensitive dyed layer) by printing heat head 32 that (label among Fig. 6 a).The bonding label 60 of temperature-sensitive according to the rotation of printing platen 33 at a predetermined angle θ from printing element 30, send out, and forward and cut in the unit 40.Then, label forwards at its deadweight effect lower edge first guide 71, arrived thermal excitation unit 50 (draw rollers 54) and locate after 0.4 second.Simultaneously, according to the rotation of draw rollers 54, the bonding label 60 of temperature-sensitive forwards (the label b among Fig. 6) with the speed of 20 mm/second.Because draw rollers 54 is driven by same drive source (second stepping motor 111) with the platen 53 that is used for thermal excitation, draw rollers 54 is identical with the driving time of the platen 53 that is used for thermal excitation in Fig. 6.In Fig. 8, Figure 10 of introducing after a while and Figure 12 all is like this.
After 0.25 second, promptly when the bonding label 60 of temperature-sensitive forwarded out after 5 millimeters when the arrival draw rollers 54 of label front end from draw rollers 54 and is used in the space between the platen 53 of thermal excitation, the rotation of draw rollers 54 (with the platen 53 that is used for thermal excitation) stopped (the label c of Fig. 6).Afterwards, because draw rollers 54 is not driven, so the front end of the bonding label 60 of temperature-sensitive do not forward, however label forward from printing element 30 by printing platen 33, unclamp thereby produced.
At this moment, because the bonding label 60 of temperature-sensitive discharges from forward direction modifier (printing platen 33 and printing heat head 32) and is inserted in the direction of insertion modifier (a pair of draw rollers 54) with predetermined angle, the direction of therefore unclamping label depends on heeling condition (in Fig. 5 up).Because the bonding label 60 of temperature-sensitive unclamps in the mode of raising in tag storage part 74, according to the function of second guide 72 and 73, it can not apply too big pressure to label.Therefore, even the bonding label 60 of temperature-sensitive unclamps, the outward appearance of label can be not impaired because of the wrinkle that is produced in the label yet.
Then after 0.2 second, draw rollers 54 (with the platen 53 that is used for thermal excitation) recovers rotation, and the bonding label 60 of temperature-sensitive forwards (the label d among Fig. 6) with the speed of 100 mm/second.Afterwards, though the bonding label 60 of temperature-sensitive is also forwarded by the platen 53 that is used for thermal excitation, yet not there are differences in the speed that forwards of draw rollers 54 and the forwarding between the speed of platen 53 that be used for thermal excitation, this is because they are driven by identical drive source, therefore, in draw rollers 54 be used for can not producing between the platen 53 of thermal excitation and unclamp and invalid tension force.
In this, because the tag length that is forwarded by printing platen 33 is 85 millimeters, the tag length that is forwarded by draw rollers 54 is 5 millimeters, and the distance between printing platen 33 and the draw rollers 54 is 40 millimeters, has so just produced about 40 millimeters (=unclamping 85-5-40).Because this of label unclamp, can carry out below the operation that cuts of the label that will introduce, and the platen 53 that need not make draw rollers 54 and be used for thermal excitation stops the rotation.
Afterwards, the bonding label 60 of temperature-sensitive is according to the rotation of three rollers 33,54 and 53 and forward with the speed of 100 mm/second.Therefore, the amount of unclamping of label can not change.After finishing predetermined printing (200 millimeters), the rotation of printing platen 33 stops (the label e among Fig. 6).Afterwards, movable scraper 41 is driven one section preset time (0.4 second), thereby cuts the bonding label 60 of temperature-sensitive (the label f among Fig. 6).At this moment, the platen 53 that is used for thermal excitation continues rotation, and the bonding label 60 of temperature-sensitive keeps forwarding.Because the tag length that is forwarded by draw rollers 54 when driving movable scraper 41 (0.4 second) is 40 millimeters, therefore cuts when the label that is unclamped forwards and finish.
When the rear end of the bonding label 60 of temperature-sensitive during by draw rollers 54, the rotation of draw rollers 54 stops (the label g among Fig. 6), and the platen 53 that the bonding label 60 of temperature-sensitive is used to thermal excitation forwards same as before.
As mentioned above, thermal printer P1 according to this embodiment, need not stop temperature-sensitive because the bonding label of temperature-sensitive 60 cropped unit 40 cut and excite forwarding of the bonding label of temperature-sensitive in the unit 50, therefore can prevent because of the adhere to each other paperboard that produces and forward fault of the temperature-sensitive adhesive layer of the bonding label 60 of temperature-sensitive and heat 52 (heating element heater 51) that are used for thermal excitation.
In addition, according to above-mentioned thermal printer P1, contact with the temperature-sensitive adhesive layer of the bonding label 60 of temperature-sensitive owing to be used for the heating element heater 51 of the heat 52 of thermal excitation, heating element heater 51 can be directly passed to heat the temperature-sensitive adhesive layer, and thermal excitation can be carried out effectively.In addition, because hot 52 51 of heating element heaters carry out thermal excitation and distribute heat during excited target, therefore can reduce the required energy consumption of thermal excitation.
Second embodiment of method for control speed is the speed that forwards the control method that the bonding label 60 of temperature-sensitive is unclamped that is lower than printing platen 33 in thermal printer P1 by the speed that forwards that makes draw rollers 54.Fig. 7 is the view that is used to describe the state that forwards of the bonding label 60 of temperature-sensitive, and Fig. 8 is the time diagram corresponding to each state of Fig. 7.
In first embodiment, the rotation of draw rollers 54 stops when the front end of the bonding label 60 of temperature-sensitive arrives draw rollers 54 and be used for place, space between the platen 53 of thermal excitation, thereby unclamp label, yet the difference of second embodiment and the foregoing description is, need not stop draw rollers 54 and just can unclamp label.In addition, owing to must when the front end of the bonding label 60 of temperature-sensitive arrives platen 53 places that be used for thermal excitation label be unclamped predetermined length in this embodiment, the speed that therefore initially forwards is set at 5 mm/second according to the rotation of draw rollers 54.
That is to say, in case the front end of the bonding label 60 of temperature-sensitive arrives draw rollers 54 places, draw rollers 54 just begins rotation, so just the speed with 5 mm/second forwards the bonding label 60 of temperature-sensitive, thereby has produced unclamp (Fig. 7 B and the 7C) that difference because of the speed that forwards of printing speed that forwards of platen 33 and draw rollers 54 causes.
The 3rd embodiment of method for control speed stops the control method that label is unclamped in the rotation of draw rollers 54 when arriving draw rollers 54 at the front end of the bonding label 60 of temperature-sensitive and being used for place, space between the platen 53 of thermal excitation in thermal printer P1.Fig. 9 is the view that is used to describe the state that forwards of the bonding label 60 of temperature-sensitive, and Figure 10 is the time diagram corresponding to each state of Fig. 9.
In first embodiment, after having been unclamped predetermined length, recovers by label the rotation (the label d among Fig. 6) of draw rollers 54 immediately.Yet the difference of the 3rd embodiment and the foregoing description is, being rotated in of draw rollers 54 finish printing and label cut after recovery (the label f among Figure 10).
That is to say, in first embodiment, not change among the figure of the amount of unclamping of label after Fig. 5 C that this is that the bonding label 60 of temperature-sensitive forwards with the speed of 100 mm/second because of the rotation according to three rollers.Yet in this embodiment, the amount of unclamping of the bonding label of temperature-sensitive increases, and this is because the rotation of draw rollers 54 stops (Fig. 9 D).
The 4th embodiment of method for control speed is lower than the control method that the speed that forwards of the platen 53 that is used for thermal excitation is unclamped the bonding label 60 of temperature-sensitive by the speed that forwards that makes draw rollers 54 in thermal printer P1.Figure 11 is the view that is used to describe the state that forwards of the bonding label 60 of temperature-sensitive, and Figure 12 is the time diagram corresponding to each state of Figure 11.
In a second embodiment, the speed that forwards of draw rollers 54 increases (the label c among Fig. 8) immediately after label having been unclamped predetermined length.Yet the difference of this embodiment and the foregoing description is, the speed that forwards of draw rollers 54 finish printing and label cut after increase (the label f among Figure 12).
That is to say, in a second embodiment, not change among the figure of the amount of unclamping of label after Fig. 7 C that this is that the bonding label 60 of temperature-sensitive forwards with the speed of 100 mm/second because of the rotation according to three rollers.Yet in this embodiment, the amount of unclamping of the bonding label of temperature-sensitive increases, and this is that the speed that forwards of draw rollers 54 remains lower (Figure 11 D) because of the rotation according to draw rollers 54.
Because the speed that forwards of draw rollers 54 is 5 mm/second, this speed is more much smaller than the speed that forwards 100 mm/second of printing platen 33, therefore the front end of label can not arrive platen 53 places that are used for thermal excitation, even be like this when finishing the back 200 millimeters label of predetermined printing and be printed that platen 33 forwards yet.In addition, preferably according to draw rollers just in time the label that cuts unit 40 cut finish after the rotation of (for example after 0.25 second) increase the speed of forwarding.
Above-mentioned first to the 4th embodiment relates to thermal printer P1 shown in Figure 1, also can unclamp label by the thermal printer that adopts following method for control speed, have the structure that is different from draw rollers shown in Figure 1 54.
The 5th embodiment of method for control speed is that the speed that forwards by the platen 53 by being used in thermal excitation in not being provided with the thermal printer of draw rollers 54 that temperature-sensitive excites unit 50 is lower than the control method that the speed that forwards of printing platen 33 is unclamped the bonding label 60 of temperature-sensitive.Figure 13 is the view that is used to describe the state that forwards of the bonding label 60 of temperature-sensitive, and Figure 14 is the time diagram of driving condition that has shown printing platen 33, movable scraper 41 and be used for the platen 53 of thermal excitation.
In this embodiment, the speed that forwards that will be used for the platen 53 of thermal excitation owing to consider the thermal excitation time of temperature-sensitive adhesive layer is fixed as 100 mm/second, the speed that forwards of printing platen 33 is set at 200 mm/second, thereby has produced speed difference.
In the printing machine shown in Figure 13 of draw rollers 54 was not set, the platen 53 that is used for the heat 52 of thermal excitation and is used for thermal excitation can be used as the direction of insertion modifier.In this case, they are arranged so that the tangential direction and the horizontal direction of heat 52 that is used for thermal excitation and the contact point of the platen 53 that is used for thermal excitation are inclined to a predetermined angle.
As mentioned above, according to the method for control speed of being introduced in the above-described embodiments, under the bonding label 60 of temperature-sensitive is clipped in situation between platen 53 that is used for thermal excitation and the heat that is used for thermal excitation 52 (heating element heater 51), need not stop just to forward and to cut label.Therefore, can prevent from for example to stick to the shortcoming of the paperboard that causes on heat 52 (heating element heater 51) that are used for thermal excitation, thereby greatly improve the production efficiency of adhesive label because of the bonding label of temperature-sensitive.
As mentioned above, though describe the present invention who makes by the inventor in detail according to these embodiment, the present invention is not limited to the foregoing description, but can carry out various modifications without departing from the spirit thereof.
For example in the above-described embodiments, though introduce applying the present invention to heat transfer printing device such as thermal printer, the present invention also can be used for ink jet printing method, laser printing method etc.In this case, must be suitable for processing that each printing process can be carried out on its printed layers rather than temperature-sensitive printed layers to label.
Too short and can't unclamp the time when label, being rotated in of printing platen 33 stops after finishing printing, and the rotation of draw rollers 54 simultaneously also stops so that cutting label.At this moment, the front end that is designed so that label can not arrive platen 53 places that are used for thermal excitation.For example, be provided with guider such as guide rail on the direction, make to cut unit 40 and thermal excitation unit 50 can move along the direction that forwards of label, thereby regulate the distance between them forwarding of label.In addition, can cut unit 40 and this distance is regulated in thermal excitation unit 50 by moving in the vertical direction.
According to the present invention, forwarding and cutting method of temperature-sensitive pasted paper in a kind of printing machine is provided, printing machine comprises: printing equipment, it has be used for the printing mechanism of printing on the printed layers of temperature-sensitive pasted paper, the temperature-sensitive pasted paper is by the lip-deep printed layers that is formed on sheet form base and be formed on another lip-deep temperature-sensitive adhesive layer and form, printing equipment also has first and forwards device, is used for forwarding the temperature-sensitive pasted paper along predetermined direction; Be arranged on printing equipment cutting means afterwards, be used for the temperature-sensitive pasted paper is cut into predetermined length; The thermal excitation device, it comprise be arranged on after the cutting means be used to heat the heater of temperature-sensitive adhesive layer and be used for forwarding second of temperature-sensitive pasted paper along predetermined direction forward device, in described method, forward the speed control of device and after paper temporarily unclamped between cutting means and thermal excitation device, stop first and forward the operation of device forwarding device and second so that cut paper with cutting means according to first.Therefore, since the temperature-sensitive pasted paper can be when forwarding device and forward or before the front end of temperature-sensitive pasted paper arrives the heater place by second cropped cutting device, for example just can solve paper because of the jammed shortcoming of the adhesion of temperature-sensitive pasted paper and heater, and need not to carry out unworthy maintenance, for example take out the label that causes paperboard.Therefore, can greatly improve the production efficiency of adhesive label.
