Definitions

  • the invention relates to a cutting device, in particular but not exclusively for use in a printing device, for cutting printed tape.
  • the multilayer tape has an image receiving layer and a back layer attached thereto by means of an adhesive layer. After the image-receiving layer has been printed with an image, the back layer can be removed so that the image-receiving layer can be attached to an object with the aid of the adhesive layer.
  • Printing devices of this type have a cutting device for cutting off a section of the tape after the image-receiving layer has been printed with an image, so that this section of tape can be used as a label. For this purpose, the cutting device has a blade which is used to cut through all layers of the multilayer tape.
  • the cutting device has a so-called tab cutting blade, which serves to cut through only one of the layers of the multilayer tape, either the image-receiving layer or the backing layer, the other layer remaining intact.
  • a device is manufactured and sold by the applicant under the designation DYMO 6000, in which a tabular cutting blade is provided which cuts through the top image-receiving layer while the back-side layer remains intact. With one It is possible to easily separate the image-receiving layer from the back layer by tabulation.
  • the tabular cutting blade is a ceramic blade that is inserted as a mold insert in a tabular cutting blade carrier, whereby it protrudes by approximately 100 ⁇ m.
  • a force is applied to the blade carrier so that the blade cuts through the image-receiving layer of the tape while the tape is supported on a flat anvil surface. Since the amount by which the blade protrudes from the blade carrier is set precisely, a reliable tab cut is ensured in which the blade always cuts through the image-receiving tape, but leaves the back layer intact.
  • an anvil is mounted such that it can roll against a cutting blade, so that the anvil is rolled down against the blade in order to make a cut is, whereby a cut is gradually made across the width of the tape. In this way, the tape is not cut at the same time, so that the actuating force required for the cut is significantly lower.
  • a cutting device for performing cutting operations on a multi-layer tape, the cutting device having a first and a second cutting blade, the first cutting blade being arranged to cut through all layers of the multi-layer tape, and the second cutting blade so is arranged so that it cuts through one or more layers of the multilayer tape, but leaves at least one layer intact, and is spaced in the longitudinal direction of the tape from the first cutting blade; and an anvil holder carrying first and second anvils which are arranged to cooperate with the first and second cutting blades, respectively, and are mounted so as to be rollable that the cutting operations are carried out while the rolling movement is being carried out across the width of the belt.
  • the first and second cutting blades are preferably attached to a common blade carrier.
  • the cutting device is particularly suitable for use in printing devices of the type described above.
  • the invention thus also specifies a printing device which uses a cutting device of the type described above.
  • a printing device may include an input device in the form of a keyboard or the like for entering user-defined information such as characters to be printed, length and format of the label and the like.
  • Such a printing device also has a printing unit with a print head and a counter-pressure roller for carrying out printing processes.
  • an image receiving tape is guided through the printing unit in overlap with a thermal transfer tape, the image receiving tape being a multilayer tape.
  • the tape is transported through the printing zone by means of a motor that drives the platen roller or a set of transport rollers to pull the tape through the printing zone.
  • Printing devices of this type have a controller in the form of a microprocessor which controls the time of printing in relation to the tape movement and in accordance with the data entered by the user via the input device.
  • the thermal print head contains a column of printing elements, so that the ribbon is printed with an image column by column as it is guided past the printing unit.
  • a label is generally drawn up, printed, and then a portion of the tape is cut to form this label.
  • a cutting device in such a way that only a tab cut is made at intervals along the length of the tape in order to define the respective labels, which can then be detached from a common back without that part of the tape has been cut off completely.
  • this is achieved by a component contained in the cutting device, by means of which the first cutting blade is optionally put out of operation. This can be controlled depending on the distance the anvil holder has traveled.
  • the only decisive factor in distinguishing between a tabular cutting blade and a full cutting blade is the extent to which the blade protrudes from the blade carrier. This means that a common blade holder can be used for the tabular cutting blade and the full cutting blade.
  • a cutting device for performing cutting operations on a multi-layer belt, the cutting device comprising: a guide arrangement extending across the width of the belt and substantially parallel to the belt plane; and a cutting component that is movably supported under the guidance of this guide arrangement, whereby a cutting process is accomplished by moving the cutting component over the width of the belt.
  • FIG. 1 shows a top view of a cutting device, as was described in our older European application with the publication number 0711637, in a printing device which has a printing device and in which a cassette is inserted.
  • the reference number 2 denotes a housing of the printing device which has a cassette receiving space.
  • the printing device has a print head 10 and a counter-pressure roller 12 which is operatively connected to the print head in order to print on an image receiving tape T.
  • the print head 10 and the counter-pressure roller 12 are mounted on the base plate 4 in the interior of the housing 2. The print head 10 can be moved from the operating position shown in FIG.
  • Reference numeral 14 denotes a cassette inserted in the cassette accommodating space.
  • the cassette 14 contains a supply of ink ribbon and image receiving tape, which are passed in mutual overlap between the platen roller and the printhead. The ribbon is then rewound into the cassette 14, while the image receiving tape is being transported out of the printer.
  • Reference numeral 16 designates the printing zone through which the image receiving tape and ink ribbon are guided in mutual overlap
  • reference numeral 18 designates the zone in which the tape exits the printer. Between zones 16 and 18 is an area in which the cutting process takes place, as will be described in more detail later.
  • the cutter consists of two main parts.
  • the first part has a cutting body 20 on which a blade 22 is attached.
  • the blade 22 serves to cut through the tape T in its entire thickness, whereby it enters a slot 24, which is located in the cassette 14 at a first cutting location C1.
  • the cutting body 20 moves on supports 56, 58.
  • the cutting body 20 On its surface adjacent to the tape T, the cutting body 20 has a tape holding clamp 28 in order to hold the tape T against a support surface of the cassette 14 during the cutting process.
  • the reference number 26 denotes one of two strap holding springs assigned to the respective support 56, 58.
  • the tape is a tape made up of several layers with at least an upper layer, an adhesive layer and a backing layer which can be removed from the adhesive layer in such a way that the upper one Layer can be attached to an object by means of the adhesive layer.
  • the top layer of the tape is printed with an image or information.
  • the upper layer of the tape T is on the right in the picture on the side facing the print head.
  • the second part of the cutting device has a blade carrier 30 which carries a so-called tab cutting blade 32.
  • the carrier 30 for the tab cut blade is mounted in a tab cut spring body 34, which in turn is resiliently biased against a tab cut support part 36 of the printer.
  • This part of the cutting device also has a so-called roller anvil 38.
  • the roller anvil 38 is rolled down against the tab cutting blade 32, a cut being made gradually over the width of the band T. The depth of cut is controlled so that the cut runs only through the upper band layer, while the back layer remains intact.
  • the roller anvil 38 can be seen more clearly from FIG. 2, which represents a section along the line II-II according to FIG. 1.
  • the anvil has an arcuate surface 3 and an actuating part 38a.
  • Figures 1 and 2 show the roller anvil in its starting position.
  • the movement of the roller anvil 38 is controlled by two guides, namely a first guide 40 facing the housing 2 of the printer and a second guide 42 facing inward of the cassette receiving space.
  • the guides 40, 42 are provided with guideways for the movement of the Rollambosses 38 to control.
  • the anvil has two projections, for example in the form of balls or pins, which are arranged in the vicinity of the respective ends of its arcuate surface 3.
  • the pens are not apparent from Fig.
  • An actuating pin 48 for the cutting body is also mounted on the roller anvil. This pin is located on the side of the anvil 38 which faces away from the viewer in FIG. 2.
  • the cutting body 20 has a guide path 50 shown in FIG. 2, in which the actuating pin 48 attached to the anvil 38 is guided.
  • the guideway 50 extends at an angle, as shown in FIG. 2.
  • Fig. 2 shows the starting position.
  • the return spring 8 which is arranged between the upstanding part 6 around the deflection roller 52 and the actuating pin 48 for the cutting body, is in a relaxed state.
  • the guide pins are held in an upper part of the guideway.
  • the cutting body 20 is in a position in which it holds the blade 22 at a distance from the band T.
  • the actuating part 38a of the roller anvil 38 moves in the direction of arrow A according to FIG. 2. The movement of the anvil is controlled by the movement of the guide pins in the guideway.
  • the movement is controlled in such a way that the arch-shaped anvil surface is unrolled along the surface of the tab cut blade carrier 30, the tape being gradually provided with a tab cut, while passing the second cutting location C2.
  • Guide pins and guideway are positioned to ensure accurate, reproducible roll motion.
  • FIG. 3 shows a practical embodiment of a cutting device according to an embodiment of the invention.
  • This cutting device is provided for those cases in which a cassette such as the cassette 14 shown in FIG. 1 does not have a support wall for the tape with a slot 24, but instead closes with a guide part behind the printing location.
  • the cutting device is thus arranged completely outside the cassette boundary, where the tape comes out of the cassette.
  • the cassette is not required to contain both an image receiving tape and a thermal transfer tape.
  • the thermal transfer belt could be accommodated in a separate cassette, or it could be dispensed with entirely.
  • FIG. 4B shows an ink ribbon cassette 214, in which there is a supply of ink ribbon or thermal transfer ribbon, and a substrate cassette 216, in which a supply of image receiving tape is located.
  • the image receiving tape and the ink ribbon are passed through each other in registration between the print head 210 and the platen roller 212 to perform a printing operation.
  • FIG. 4A is a view from the side of FIG. 4B in the direction of arrow IV. It can thus be seen that the base plate 222 of the printing device carries the ink ribbon cassette 214 and the carrier cassette 216. FIG. 4A also shows how the tape T emerges from the device in the direction of the viewer.
  • the cutting device 220 itself will now be described in more detail below.
  • the cutting device has a blade carrier 100, in which a full cut blade 102 and a tab cut blade 103 are held, the former serving to make a cut extending through the total thickness of all layers of a multi-layer tape, while the latter cuts through just one or more Layers of a multi-layer tape is to be carried out, with the back layer remaining intact.
  • the cutting device also has an anvil holder 104 which carries two "roller anvils" 106, 108.
  • the first roller anvil 106 has the function of interacting with the full cut blade 102, while the second roller anvil 108 serves to interact with the tabular cutting blade 103.
  • the anvil holder 104 is in the form of a central shaft rotatable about an axis AA.
  • the roll anvils each have a narrow circumferential slot 106a and 108a.
  • the slots are aligned with the blade assigned to them in such a way that there is no direct contact between the blade and the anvil.
  • Fig. 3 shows a schematic representation of the tape T when leaving the cassette and during its further transport to the cutting device in the direction of arrow B.
  • the cutting locations C1 and C2 are arranged at a distance from one another in order to make a full cut at the cutting location C1 and perform a tab cut at the cutting location C2, the desired cutting mode being selected in the manner described below.
  • FIG. 5A shows the cutting device from its front side. This view is obtained by looking at the tape T along its way out of the cassette.
  • the blade carrier 100 can thus be viewed in section, the full-cutting blade 102 being visible.
  • the width of the band is designated w. This value is variable depending on the width of the tape inserted.
  • the anvil holder 104 is mounted on a carriage 110 and is biased against the blade carrier 100 by the action of a spring 112 under constant force. The downward force is indicated by the arrow F. Under the action of a motor-driven one Guide spindle 114, the carriage can be moved back and forth across the width of the belt T. When the carriage is driven by the lead screw, the roller anvils 106 and 108 are rotated, thereby cutting the tape T against the action of the blades at the cutting locations C1 and C2.
  • FIG. 5B shows a section through the carriage 110, the mode of operation of which can be seen more clearly.
  • the guide spindle 114 extends through an opening 115 in the slide 110 and is received in threaded nuts 117 at both ends of the opening. Rotation of the lead screw 114 thus causes the carriage 110 to move laterally in FIG. 5B.
  • the carriage 110 consists of a main part 110a and a pivotable part 110b.
  • the pivotable part 110b has a recess 119 for receiving the holder or shaft 104 of the roller anvil.
  • the pivotable part 110b is hinged to the main part 110a by means of a hinge 110c.
  • spring 112 acts between main body 110a and pivotable body 110b to apply downward force F, as set forth above with reference to FIG. 5A.
  • the slide is made in one piece, the pivotable part 110b being open to the main part 110a. This is shown in more detail in Fig. 5C. Because the carriage is made in one piece, the spring can be attached to the carriage and the pivotable part 110b can be folded back in the direction of the arrow Y, which simplifies production.
  • the full-cut blade can either be put into or out of operation, so that the cutting device either carries out a full cut with a tabular cut or only a tabular cut.
  • a cutting device that offers this possibility is shown in FIG. 6.
  • FIG. 6 is a view corresponding to FIG. 3, the roller anvils 106 and 108 being shown attached to the anvil holder 104.
  • the full cut blade 102 is mounted on a cutting blade pin 116 which is actuated by a slide 118.
  • the slide 118 is an essentially flat component with an elongated part which is guided in a guide groove 120 formed in the blade carrier 100.
  • 7A shows an end view of the cutting device, the slide being shown in more detail. 7A shows the slider in its retracted position.
  • the slide 118 On its right side in FIG. 7A, the slide 118 has a cam part 122, against which the cutting blade pin 116 bears.
  • the slider 118 On its left side in FIG. 7A, the slider 118 has an actuating part 124 which extends upwards from the elongated part of the slider.
  • the actuating part 124 carries an actuating element 126 which extends in the longitudinal direction of the blade carrier, ie in the direction in which the carriage 110 moves.
  • Figure 7A shows the anvil holder 104 in its home position, at the far left end of its path, as shown in Figure 7A. In this position, it holds the actuating part 124 of the slider 118 so that the cam part 122 holds the cutting blade pin 116 down, the full cutting blade 102 disengaging. Now roll the anvil holder 104 from its starting position to the right in Fig. 7A in the direction of arrow C, only a tab cut is made on the tape.
  • the anvil bracket 104 has two stop positions, an inner stop position as shown in FIG. 7B and an outer stop position as shown in FIG. 7C. In the inner stop position, the shaft of the anvil holder abuts the stop 128 of the actuator 126 and thus does not cause the slide 118 to move. The full-cut blade thus remains disengaged and when the anvil holder returns to its original position on its return stroke from the inner stop position also not a full cut on the label.
  • the slider 118 through its cam portion 122, causes the cutting blade pin 116 to move downward so that the full cutting blade 102 is in its inactive position.
  • the next extension stroke of the anvil holder 104 does not result in a full cut.
  • the present embodiment only allows a full cut to be made during the return stroke of the anvil holder 104.
  • Fig. 8 shows the starting position, the inner stop position and the outer stop position with respect to the maximum width of the tape T.
  • This arrangement enables a user to choose whether a full cut with tabular cut or only a tabular cut should be carried out. This can be done automatically with the aid of the arrangement according to FIG. 9.
  • the blade carrier is not shown in FIG. 9, but the carriage 110 with the roller anvil 106. As described above in connection with FIG. 5A, the carriage 110 runs on a guide spindle 114.
  • the reference number 200 denotes a DC motor with which the Leading spindle is driven via a reduction gear pair 202.
  • a first leaf spring switch 204 is provided, which detects the starting position of the anvil holder 104.
  • the detection of the inner and outer stop position is achieved by a second leaf spring switch 206, which detects the revolutions of a second gear wheel of the reduction gear pair 202. This can be done, for example, with the help of a front cam on the second gear wheel. With each revolution of the guide spindle 114, a pulse is thus generated at the second leaf spring switch 206, as a result of which a simple rising rotary encoder is formed. 10 shows the respective signals from the leaf spring switches 204 and 206.
  • the leaf spring switches 204 and 206 are referred to here as diagnostic switches.
  • FIG. 11 shows a block diagram of a circuit arrangement for a printing device for carrying out the above-mentioned feature.
  • FIG. 11 shows a central controller 300 for the printing device, which has a microprocessor with a read-only memory ROM 302 and a random access memory RAM 304.
  • the controller 300 is with an LCD driver 309 connected to control a display device 308 of the printing device. As indicated by the jagged line across the connection between the controller 300 and the LCD driver 309, the display device and associated driver may be located away from the printing device.

  • control circuit 300 receives corresponding signals from the cutting diagnostic switches 204, 206, by means of which it can determine the position of the carriage. It can therefore cause the direction of movement of the anvil holder to be reversed either at the inner or outer stop position.
  • step 400 A more detailed illustration is shown in FIG. 12, in which the start of a cutting process is shown at step 400.
  • a cutting operation can be triggered by the user pressing a cutting key on the keyboard 306 or automatically by the device itself after it has printed a certain length of labels.
  • step 402 control checks whether a full cut is required. This must be set by the user at the time the label is formatted or when a cutting operation is initiated. Depending on the result of the test, a number N is set which is equal to the number of switching pulses to be expected from the diagnostic leaf spring switch 206. If a full cut is required, the number N is set to N2, while for a tabular cut alone, the number N is set to N1.
  • N1 is logically smaller than N2, since the extension stroke of the carriage 110 is shorter in the case of a tab cut than in the case of a full cut on the return stroke.
  • Step 404 the carriage 110 is moved outward by starting the engine 200.
  • Diagnostic leaf spring switch 204 determines when the carriage has passed the home position, as indicated by transition 405 in FIG. 10. This transition is recognized in step 406, and the The controller then counts the increasing switching pulses derived from the diagnostic leaf spring switch 206. If N is equal to the preset number (N1 or N2, depending on the determination in steps 403a, 403b), the direction of rotation of the motor is reversed in step 407 to drive the carriage 110 inwards. If the signal for the starting position is reached (step 408), the sequence of steps is ended (step 409).
  • the diagnostic leaf spring switch 204 (see Figure 9) is used to turn off the DC motor 200 when the anvil bracket 104 returns to its home position. This is not caused directly, but rather by the software of the controller 300.
  • a user can thus request labels with or without a full cut via a user interface of the printing device.
  • a sequence of labels can also be produced in the strip mode, and after the last of these labels the control circuit can cause the cutting device to carry out a full cut with the last tab cut in order to separate the label strip from the printing device. Further details on the manner in which labels can be produced in the so-called "strip mode" are disclosed in our older European patent application with the publication number 0578372. The content of this application is hereby incorporated by reference.
  • the flow chart in Fig. 13 shows how a sequence of labels can be produced in the strip mode, the strip being cut off at the end with a full cut.
  • the flowchart in Fig. 13 begins at the point where a user has requested a sequence of p labels, the single label only from its neighboring label is separated by a tab cut, but the labels remain attached to a common strip of backing tape. This is identified in the flowchart by step 500.
  • step 504 the processor then prints the first label in the sequence.
  • step 506 p is increased by 1 and compared in step 507 with P. It is clear that p is not equal to P on the first label, and consequently the full cut blade is put out of order as explained above. Thus, only a tab cut is performed, as shown in step 510.
  • the user can also use the data entry keys to enter a number which then appears on the display in block 601 next to the selected option.
  • the processor determines in step 602 whether one or more copies have been requested. If it is only a single label, the label is printed at step 604, whereupon the cutting process at step 606 includes a full-cut tab cut.
  • the processor recognizes this at step 608. If a full cut is selected, a sequence of copies of a label is printed and individually cut with a full cut as shown in a series of steps 610, 612 and 614.
  • the processor In contrast to a full cut, the processor must also take the lead length of a label into account when working in strip mode. This can be done in the manner described in EP 578372.
  • the user can request multiple copies of the same label.
  • the printer can count the number of copies and, if desired, display this to a user.
  • the display shows how many copies have been printed or are still to be printed.
  • the printing device can be set up so that it delivers so-called increasing copies. This means that the printer can print a series of labels with each label assigned a number, with subsequent labels having that number plus 1.
  • the user can select the number of labels that will be printed with the same increasing number. For example, he could select 3 copies of labels that have the same increasing number.
  • the lead length of a label can be reduced by starting a printing process so that a part of the label is printed, the printing process is then stopped to make a tab cut after the tape has been fed a predetermined length, and then the full label is printed. This enables shorter labels to be produced, which means that tape consumption is reduced to a minimum.
