Definitions

  • the present invention relates generally to the path of strands of a web of material leaving a printing unit of a printing press after setup and restart, and more particularly to a strand path display system to assist the operator in guiding the web strands through roller paths into designated hoppers of a folder.
  • a printed web leaving a printing unit of a printing press is cut lengthwise into a number of strands, which in turn are fed into the hoppers of a folding apparatus for folding and further processing. Since many printed products are often produced in a single printing press, the route of a strand en route to a folder changes depending on the operation to be carried out. After trimming, an operator must first pass each strand on a path through an arrangement of turning bars, register rolls, deflection rolls, intermediate rolls and guide rolls and then into a designated hopper in the folder. In the event of a web break, this process of guiding the strands must be started again.
  • An additional object of the present invention is to provide a strand path display system that is as inconspicuous as possible but easily visible, and that is not limited to displaying a number of layouts, and at the same time has the minimum data required to perform the operation displays.
  • the present invention provides a system that simultaneously displays strand path instructions to an operator as they run strands through roller paths to enable them to quickly determine the correct strand path for a selected operation.
  • the present invention provides a strand path display system which assists an operator in guiding strands of a web of material leaving a printing unit of a printing press through roller paths.
  • the system comprises a number of rollers, each of which is connected to a remote display device.
  • Each of these remote indicators consists of a directional indicator and a next reel indicator indicator and displays strand path instructions to the operator.
  • the strand path instructions include one about clockwise or counterclockwise wind direction, and one about identity of a next roll to be wound.
  • the system also provides a controller coupled to each of the remote indicators to issue commands to indicate the route instruction to each of the remote indicators.
  • the present invention provides a method of operating the thread path display system, including the steps of retrieving thread path information for a preselected operation from a memory; pressing the Controls for issuing commands based on the retrieved line route information which cause each of the remote indicators to display the respective line route information; accepting commands in each remote display; and activating each remote indicator to display its respective line path information.
  • the present invention provides a remote indicator that is mounted within each roller where strand path decisions must be made.
  • the remote indicator shows the identity of the roller belonging to it, the direction in which the strand must be wound around the roller belonging to it, and the identity of the next roller which has to be wound. This information can e.g. displayed clockwise, counterclockwise and alphanumerically using LEDs.
  • the remote indicators are coupled to a control device which comprises a railroad control system which has a processor and a memory with line path information for a plurality of operations. Thanks to the web guidance system, the displays of the remote indicators can be changed quickly and easily during preparation.
  • the rail control system is coupled to a company-wide computer network. This allows the strand path information to be created and stored at a remote location and later retrieved by the web control system for use. In addition, such a design of the invention enables a very large amount of strand path information to be stored without significantly increasing the set-up time of the system.
  • FIG. 1a and 1b show strands of a material web which move on separate roller paths into the designated hoppers of a folder.
  • a material web 10 leaves a printing unit 5, moves over a register roller 12 for the entire web and is cut into strands 20 and 30 by a slitter 14 before it arrives at a drawing roller 16. Only two strands are shown, but the material web 10 can be cut into any number of strands.
  • An operator twists it Strands 20 and 30 around guide rolls 40, 45 to respective turning bars 50 and 55. The turning bars 50, 55 change the direction of the strands 20 and 30 by about 90 °, as shown in Fig. 1b.
  • the operator then guides the strand 20 via a guide roller 60 into a designated hopper of a folder (the path of the strand 30 is not shown).
  • the respective remote indicators 80 are mounted within each roller on which strand winch and strand path decisions must be made.
  • the remote indicators 80 could be attached in a suitable manner in the area of a respective roller on which strand path decisions have to be made.
  • the remote indicators 80 must be attached so that the respective roller can be clearly identified by the operator.
  • FIG. 2 shows a roller 90, eg an intermediate roller or guide roller, with a front end 92 and a rear end 94.
  • the rear end 94 of the roller 90 is mounted on a shaft 100 which has a bore extending axially through its center.
  • the shaft 100 itself is mounted on a frame 104 of the printing press.
  • a remote indicator 80 is mounted within the front end 92 of the roller 90.
  • the remote indicator 80 is electronically connected to a web guide system 160 by means of a connecting cable 106, which is led through a bore 110 extending axially through the roller 90 and through the bore 102 in the shaft 100 to the web guide system 160.
  • FIG. 3 shows a display field 120 of a remote indicator 80 which bends a light-emitting diode 130 clockwise, a light-emitting diode 140 bends counter-clockwise and has three 7-segment light-emitting diodes 150.
  • the directional LEDs 130, 140 indicate the direction in which the strand must be wound.
  • the number of the roller (the remote indicator identifier) is dimly illuminated in the three 7-segment light-emitting diodes 150 and thus their identity is displayed if this roller has to be used.
  • the light emitting diodes 150 are also used to indicate the number of the next roller to be wrapped with stronger light (the next remote indicator).
  • the remote indicator identifier and the next remote indicator are alternately displayed by the remote indicator 80 (e.g., alternating every 5 seconds).
  • the brightness of each display can be individually adjusted by changing the pulse duration of the light emitting diode, as is well known in the art.
  • the remote indicator identifier is shown on a label 155 attached to the front of the remote indicator, as shown in FIG. 3.
  • the three 7-segment light-emitting diodes 150 are used only for the display of the nearest remote display and diagnostic information.
  • the remote indicators 80 are connected to the railroad control system 160 via a serial bus 170 which complies with the EIA-485 standard, as shown in FIG.
  • the remote indicators 80 are powered by the power supplies 172 and 174.
  • the web guidance system 160 may consist of a conventional computer capable of performing the functions described above.
  • the web control system 160 consists of a system processor 162, which contains, for example, an Intel 80286 microprocessor; a screen 164; and a keyboard 166.
  • the routing system 160 retrieves the routing information from either local storage, eg, a hard drive, or from external storage in a company-wide network 168, and uses the retrieved data to issue commands to the remote indicators 80 Displays the appropriate remote indicator identifier, directional indicator, and nearest remote indicator and diagnostic indicators. New line path information can be entered via screen 164 and keyboard 166 and stored either on the local hard drive or in external storage via company-wide network 168.
  • the line route information can also be input from remote data stations that are connected to the rail control system 160 via the company-wide network 168.
  • the embodiment described above has the advantage that it is possible to provide strand path information for one Save a large number of operations and call them up later when the operations are repeated.
  • the routing system 160 transmits on bus 170 commands that cause each remote indicator 80 to display the correct remote indicator identifier, directional indicator, and nearest remote indicator.
  • the web guidance system 160 also transmits positioning information, such as the brightness of the respective displays and the cycle in which the remote indicator identifier and the next remote indicator are displayed alternately.
  • Each remote indicator 80 has its own address, which is determined by the address module 210 coupled to the controller 200, and which enables the controller 200 to ignore commands which are intended for other remote indicators.
  • Controller 200 connects outputs to each of the four LED converters / drivers 220-223.
  • the drivers 220-222 are each connected to one of the 7-segment light-emitting diodes 150.
  • Driver 223 is connected to directional light emitting diodes 130, 140.
  • the microcontroller 200 processes those commands that it determines are intended for their respective remote indicators in accordance with a series of instructions contained in RAM or EPROM that are present in the microcontroller. In this way, the microcontroller 200 controls the LED displays 130, 140, 150 via the drivers 220-223, to display the remote indicator identifier, nearest remote indicator, and directional indicator according to the instructions.
  • Controller 200 also continuously tests for sum to detect errors in the received data stream. When a fault is discovered, a corresponding message is displayed on the 7-segment light-emitting diodes 150. Controller 200 can also be programmed to perform other diagnostic functions, such as displaying a bus off time on an LED display when no activity can be detected on bus 170, e.g. for 60 seconds. Furthermore, an EIA-485 transmitter can be provided on each remote indicator 80 so that each remote indicator 80 can act as a signal amplifier by simply connecting it serially to bus 170.
