Definitions

  • a web-slitting machine or system typically employs a number of web-slitting assemblies to cut an endless moving web, such as a continuous roll of paper or other material, into a number of strips (equal to the number of web-slitting assemblies plus one).
  • a web-slitting machine of this type is shown in U.S. Pat. No. 6,732,625, which is owned by the assignee herein.
  • the web-slitting machine supports and permits the positional adjustment of the web-slitting assemblies, thereby permitting the machine to be configured to cut any one out of a wide variety of strip width sets.
  • a typical web-slitting assembly includes a web-slitter having a blade or knife that overlaps with a lower anvil, so that together they present a scissors-like action to a continuous web of material that is pulled through the assembly by a drum or a take-up reel.
  • the web-slitter usually includes an upper carriage, which is slideably movable along a support in the form of a transverse bar, and a blade holder that includes a freely rotating disk-shaped blade.
  • the anvil which may be in the form of a drum or roller that has a sharpened edge, is positioned on a supporting sleeve.
  • the web-slitter of the '625 patent is hydraulically operated. Both the vertical motion of the blade holder and the side shift motion of the blade are controlled through hydraulic motors that are fed by fluid under pressure. Proper set-up and alignment of the blade with the lower anvil are important. Different webs require variations in blade/anvil overlap and in lateral side-shift pressure.
  • An electronically controlled web-slitter includes dual electric motors whose functions may be controlled by an electronic controller accessed either on the chassis of the web-slitter or by way of a computer coupled to the electronic controller. Vertical and side-shift blade set-up and functions are thus accurately controlled.
  • FIG. 1 is a schematic diagram of an electronically controlled web-slitter using dual electric motors.
  • FIGS. 2A and 2B are a flow chart diagram illustrating the set-up and calibration routine employed by the electronic controller to properly set the blade for a cutting operation.
  • FIG. 3 is a side view of a web-slitter schematically illustrated in FIG. 1 .
  • FIG. 4 is a partial side cutaway view of the web-slitter of FIG. 3 with the blade in a fully retracted position.
  • FIG. 5 is a partial side cutaway view of the web-slitter of FIG. 3 with the blade in the engaged position.
  • FIG. 6 is a front partial cutaway view taken along line 6 - 6 of FIG. 4 .
  • FIG. 7 is a front partial cutaway view taken along line 7 - 7 of FIG. 5 .
  • Web-slitting machinery of this type typically employs hydraulic actuators of the type shown in U.S. Pat. Nos. 5,083,489 and 6,732,625.
  • hydraulically controlled components lack precision and, in particular lack the precision that would be obtainable if an electronic controller in conjunction with electric motors were used to control both the set-up and operation of a web-slitting machine.
  • electric motors are well suited for such control.
  • Such motors may take the form of stepper motors, servomotors, or vector-controlled motors. By using stepper motors, for example, each discrete increment of movement by the motor components may be controlled by a discrete number of digital pulses generated by an electronic controller.
  • the pulse count may be stored in the controller's memory to give precise control of both vertical movement of the blade holder relative to the carriage assembly and the side-shift motion of the blade.
  • the electric motors may be connected to a computer through an interface circuit so that commands required to execute certain functions may be controlled remotely. The computer may then control an entire bank of web-slitters. Thereafter when the set-up mode is launched, each controller searches its memory for the correct sequence and pulse count needed to execute steps that cause the blades to set up correctly and interface properly with the lower anvils.
  • a web-slitter 10 includes a carriage 11 that houses an electronic controller 12 having a vertical controller 12 a and a side-shift controller 12 b .
  • Each of the controllers 12 a and 12 b has a memory unit 14 a and 14 b respectively.
  • the output of the controller 12 is a dual-axis output.
  • One output 16 drives a vertical motor 20 .
  • This motor has an output shaft 22 that is used to raise and lower a blade-holder assembly 24 .
  • the side-shift controller 12 b has a second output 18 , which drives a side-shift motor 26 .
  • the side-shift motor has a vertically-extending output shaft assembly 28 , which mechanically couples to a slitting blade 30 through a mechanical linkage 32 .
  • the linkage 32 converts the vertical movement in the shaft assembly 28 to horizontal motion of the blade 30 through the linkage 32 so that it is drawn into contact with an anvil 34 .
  • FIG. 2 shows a set-up routine employed by a preferred embodiment in which information stored in the controller boards 12 a and 12 b controls a calibration mode, which sets up the blade movement parameters for engaging the lower anvil 34 .
  • FIG. 2 illustrates the procedure for set-up and the operation of the electronic controller 12 , which includes a circuit board with chip controllers and memory that execute the control functions illustrated in the flow chart.
  • the functions of the web-slitter are controlled, either from controls on the web-slitter itself or by an outboard computer 36 .
  • the computer 36 may implement set-up, run and disengage functions and may do so for a plurality of web-slitters.
  • Web-slitters are usually arranged in a bank along a transverse bar predetermined distances apart.
  • a computer such as computer 36 , may control a plurality of web-slitters simultaneously.
  • each web-slitter may be individually controlled by control switches located on the carriage assembly 11 .
  • a front panel control 38 has three settings: “CALIBRATE;” “ENGAGE;” and “DISENGAGE.”
  • each carriage 11 has an up/down jog switch 40 .
  • the carriage 11 is positioned so that the blade 30 is slightly offset from the anvil 34 .
  • the up/down jog switch 40 is then engaged ( 102 ).
  • the first time the up/down jog switch 40 is engaged (when the blade is in an offset position relative to the anvil), the vertical motor 20 lowers the blade-holder 24 and the side-shift motor 26 draws the blade 30 towards the right into a one-half stroke side-shift position.
  • the blade 30 is moved manually to contact the anvil ( 104 ).
  • the CALIBRATE mode is then selected by control 38 and the routine starts and queries the on-board control circuit boards 12 a , 12 b shown in FIG. 1 .
  • the side-shift controller 12 b generates a signal to cause the side-shift motor 26 to go to its zero position ( 106 ).
  • the zero position is the position at which the blade 30 is fully extended away from the anvil 34 .
  • the zero position is detected by use of a photocell circuit or other contact-type or proximity sensor.
  • a command is given by the vertical controller 12 a to raise the blade 30 five-eighths of an inch (0.625′′) ( 108 ).
  • the exact distance of this step ( 108 ) is chosen only for this particular example (as shown in the preferred embodiment) and other set-up parameters, depending upon the size of the blade and other factors, may be chosen depending upon the application.
  • step 108 a command is given by the side-shift controller 12 b to move the blade 30 to its full-stroke position ( 110 ).
  • the vertical motor moves the blade toward the anvil ( 112 ) until the anvil is contacted ( 114 ).
  • the contact between the blade 30 and the anvil 34 is detected by the closing of the aforementioned electrical circuit, which is sensed by the controller 12 .
  • the output on line 16 is a series of pulses, which controls the movement of the vertical motor 20 .
  • the pulse count required to move this distance is stored in the vertical controller's memory 14 a ( 116 ).
  • the controller then sends a signal to the vertical motor 20 causing it to raise the blade-holder assembly 24 a distance of 0.02 inches ( 118 ). Again, this figure is chosen depending upon the size of the blade employed and other requirements of the user.
  • step 118 a command is given to the side-shift motor 26 to go to its zero point ( 120 ).
  • the command is then given to require the vertical motor 20 to move the blade-holder assembly 24 to its overlap position ( 122 ).
  • the overlap position is the vertical distance by which the blade 30 overlaps the anvil 34 . This distance is chosen depending upon the size of the blade and the type of material to be cut. Thinner, lighter materials do not require as much overlap between the blade and the anvil as do thicker and harder to cut materials.
  • This parameter is chosen and pre-stored in the vertical controller's memory 14 a depending upon the requirements of the user.
  • a command is then given by the side-shift controller 12 b through line 18 to cause the side-shift motor 26 to move the blade 30 toward the anvil 34 ( 124 ).
  • the pulse count required to do so is stored in the memory 14 b ( 128 ). It will be appreciated that, while merely touching the blade 30 to the anvil 34 closes the electrical circuit and therefore stops the side-shift motor 26 , slight touching is inadequate for proper set-up. Therefore, from memory 14 b a predetermined pulse count is added on line 18 to cause the side-shift motor 26 to add a certain amount of compression force for the blade 30 bearing against the anvil 34 ( 130 ). Once this occurs, the blade is now properly set up against the anvil and a cutting operation can begin.
  • control 38 may be moved to either the ENGAGE or DISENGAGE position. If the control is either left in the CALIBRATE position or moved to the ENGAGE position, once step 130 has been completed the motors stop and the unit is ready for cutting. If the DISENGAGE setting has been chosen, once step 130 has been completed both the side-shift motor and the vertical motor move to their respective positions as illustrated in steps 132 and 134 .
  • a retractable flag could be used, which would allow for manual positioning using the up/down jog switch 40 and movement of the carriage 11 along its transverse mounting bar.
  • a retractable flag of this type could be a simple plastic guide member shaped to provide an initial vertical and lateral offset between the anvil and the blade.
  • the starting position may then be stored in the memory units 14 a and 14 b of the controller 12 and the calibration routines and distances for movement (in terms of numbers of pulses required to accomplish certain tasks) may be adjusted accordingly.
  • a laser may be placed on the unit itself, which may be used to visually align the blade and the anvil prior to initiating the calibration mode.
  • a preset pulse count stored in memory provides the proper side-shift compression.
  • this function could be accomplished automatically—for example, by measuring the current draw on the motor for different preset side forces and the use of an analog sensor to stop the side-shift motor when the current draw matches the selected preset value.
  • a load transducer could be used to control the side-shift motor when the transducer measures a preset compression value.
  • a web-slitting machine 10 includes an upper carriage assembly 11 and a lower blade-holder assembly 24 .
  • the blade-holder assembly 24 supports a rotary knife/blade 30 , which bears against an anvil 34 .
  • the upper carriage 11 is mounted for sliding movement along a transverse track 42 .
  • the control knob 38 is located on the front panel of the carriage assembly 11 along with the up/down jog switch 40 .
  • the carriage assembly 11 also houses the electronic controller 12 , which is coupled through the output lines 16 and 18 respectively to the vertical motor 20 and the side-shift motor 26 .
  • the output of the vertical motor 20 is a rotating shaft 44 , which fits into a threaded sleeve 46 .
  • the sleeve 46 includes a screw follower that raises and lowers the blade-holder assembly 24 when the output shaft 44 rotates.
  • a sleeve 48 connected to the side-shift motor 26 houses a rotary shaft or rod 45 which is coupled to a follower that compresses a spring 47 , which, in turn, exerts a force that depresses a plunger 50 .
  • the spring 47 supplies the compression force that biases the blade 30 against the anvil 34 in the engaged position.
  • a spring 76 in the side-shift piston 74 (refer to FIG. 7 ) is compressed.
  • the blade however, cannot press against the anvil without being allowed to give laterally with a preset amount of restoring force.
  • the restoring force is provided by the action of the spring 47 bearing against the plunger 50 .
  • Such formulae are well known and take into account mechanical advantage provided by the other components of the linkage 32 and friction.
  • the blade-holder assembly 24 is coupled to the carriage assembly 11 through a dovetail fitting 52 and is locked into place by a locking lever 54 .
  • the dovetail fitting 52 has a receiver (not shown) for the guide rod 46 and for the sleeve 48 .
  • a bellows 56 houses the guide rod 46 and the sleeve 48 , and expands and contracts as a result of vertical movement of the blade-holder assembly 24 .
  • the cant angle of the blade 30 (about a vertical axis) is set using a cant key 58 , which is a removable key. Keys having different shapes set the appropriate cant angle chosen by the user.
  • FIG. 4 shows the web-slitter 10 in its zero position, that is, the blade is fully upwardly retracted and the side-shift mechanism is likewise retracted.
  • a spring-loaded pin 60 breaks the beam of a photocell 62 .
  • This pin moves under the control of the side-shift linkage mechanism 32 as will be explained below.
  • Another photocell 64 is controlled by a pin 66 , which moves in a vertical direction with the blade-holder assembly 24 . When the vertical motor 20 is at its fully retracted position, the pin 66 breaks the beam of the photocell 64 and turns off the vertical motor.
  • the side-shift motor 26 is turned off.
  • the photocells 62 and 64 thus function as sensors to detect the fully retracted travel points as controlled by motors 20 and 26 .
  • the photocells 62 and 64 are connected to the electronic controller 12 by appropriate circuitry (not shown).
  • the photocells 62 and 64 are just one example of sensor mechanisms that may be used to detect the limits of travel for both the side-shift and vertical motors. Other sensors, including limit switches, electrical contacts or other types of proximity sensors, may be used if desired.
  • the blade-holder assembly is fully extended and the side-shift linkage 32 has caused the blade 30 to engage the anvil 34 .
  • the output shaft (not shown) of the side-shift motor 26 pushes against the plunger 50 , which in turn depresses a lever 68 .
  • the lever is biased in an upwards position by a bias spring 70 .
  • the plunger 50 depresses the lever 68
  • the lever in turn presses downwardly against a wedge member 72 .
  • the wedge member 72 presses against an inclined surface of a side-shift piston 74 .
  • the side-shift piston 74 is normally biased outwardly by a spring 76 .
  • the wedge member 72 forces the side-shift piston against the spring 76 to thereby contact the blade 30 to the anvil 34 .
  • the mechanical linkage shown in FIGS. 4 through 7 provides one example of a means by which the movement of the vertical output rod or shaft from the side-shift motor 26 may be converted from vertical to lateral movement.
  • Many other mechanical constructions that will perform the same function are possible, including rack and pinion mechanisms, rotary cams or other gears that may be used to convert motion in a vertical direction to motion in a lateral direction.
