Definitions

  • the invention relates to a method and a device for preparing film strips for reordering orders according to the preamble of claim 1 and claim 9, respectively.
  • film strips are also entered that do not contain any negatives, of which the customer wants a picture. This is particularly the case if the customer sends all film strips with the copy order. In this way, many film strips are unnecessarily stuck to the carrier tape, which can lead to a massive loss of productivity in the preparation station and much more in the subsequent automatic processing stations.
  • the film strips belonging to a customer order are fed into a preparation station. There they are glued to a carrier tape and wound up into a film roll, which can be used in subsequent processing stations.
  • the customer-specific order data relating to the desired number of copies of certain master copies and, if appropriate, the desired copy format are also entered into the preparation station via an input unit and stored on a carrier medium which is compatible with the subsequent processing stations.
  • the customer-specific order data is entered before the film strips are fed in.
  • the fed-in film strips are automatically examined before they are glued to the carrier tape with regard to their position parallel to the direction of transport and with regard to the number sequence of the copying templates on the respective film strip, and a comparison is made with the entered customer-specific order data to determine whether the fed-in film strip is necessary for processing the customer order is.
  • the operating personnel is automatically made aware of the respective error, or the relevant film strip is automatically ejected before it is stuck to the carrier tape. In this way, operating errors are compensated by the operating personnel and the Source for possible malfunctions and / or incorrect further processing of the master copies, for example incorrect exposures, reliably avoided.
  • Film strips entered at an angle or incorrectly no longer have to be laboriously detached from the carrier tape By automatically eliminating film strips that are superfluous for the processing of a customer order, since no images of the copy templates contained on them are desired, preferably, productivity losses at the preparation station and in particular at the subsequent processing stations are avoided.
  • a film strip is inserted in such a way that it activates a sensor which is arranged directly in front of a pair of feed rollers and, depending on the length of the film strip, activates at least one further photoelectric sensor which, in the input area of the preparation station, is parallel to the transport direction of the film strip in one predetermined distance from the first sensor is arranged.
  • Activation of the first sensor starts a drive for the pair of feed rollers and, if necessary, for further pairs of transport rollers.
  • the film strip is pushed forward by hand until its front edge is gripped by the pair of feed rollers and the film strip is automatically drawn in further.
  • the rotation of the counter roller of the pair of feed rollers is measured with a rotation sensor, preferably with an angle encoder, in order in this way to measure the distance covered by the film strip.
  • a rotation sensor preferably with an angle encoder
  • the leading front edge of the film strip is detected and a DX code with start and stop sequence and with a coded original number is read on the side of the first copy document. From the legibility of the DX code, the correct position of the film strip can be deduced. The position of the layer side of the film strip is determined from the position of the DX code.
  • the start sequence of the DX code is in front of the coded master number, an increasing number sequence is inferred, or if the stop sequence of the DX code is in front of the coded master number, a descending number sequence is inferred.
  • the length of the film strip is determined from the distance of the responsive sensor in front of the pair of feed rollers and the detected revolutions of the counter roller of the pair of feed rollers.
  • the copy template numbers on the film strip can be determined from the length of the film and the information about the increasing or decreasing number sequence of the master copies. Based The device table previously entered is then automatically decided whether copies of the copy templates on the film strip in question are desired.
  • the filmstrip in question is transported on to a pair of deflecting rollers over which a carrier tape is guided, to which the filmstrip is subsequently adhered.
  • it can be automatically ejected against the direction of insertion by reversing the rotational movement of the feed roller pair and possibly further transport roller pairs or via an alternative transport path be removed from the prep station.
  • the device according to the invention for the preparation of film strips for reordering orders comprises an input area in which a number of film strips of a customer order having copying templates are fed along a work surface to a pair of feed rollers, an adhesive station for adhering the fed film strips to a carrier tape which is guided over a pair of deflection rollers, and a computer unit in which customer-specific order data relating to the desired number of copies of certain copy templates and, if appropriate, the desired copy format are entered and recorded on a storage medium compatible with further processing stations.
  • At least a first and a second photoelectric sensor for detecting the side edge and the rear end of a fed film strip are provided in front of the feed roller pair at a predetermined distance from the feed roller pair.
  • the first sensor which is closer to the feed roller pair, controls drive means for the feed roller pair and, if appropriate, further transport roller pairs.
  • the counter roller of the pair of feed rollers is connected to a rotation detector, preferably an angle encoder.
  • a photoelectric scanning unit is arranged, which detects the advanced front edge of the filmstrip and is designed to recognize template numbers which are printed on the side of each template on the filmstrip.
  • the photoelectric sensors, the rotation detector, the photoelectric scanning unit, the drive means for the feed roller pair and possibly further transport roller pairs as well as drive means for the Deflecting roller pairs in the gluing station are connected to the computer unit in such a way that, on the one hand, detected signals and information are sent to the computer unit and, on the other hand, control signals can be given to the corresponding drive means and, if appropriate, other connected transport means for the film strips. With the device designed in this way, the method according to the invention can be carried out very easily.
  • three photoelectric sensors for detecting the side edge and the rear end of a fed film strip at a predetermined distance from the feed roller pair are preferably located in front of the feed roller pair in relation to the transport direction of the film strips intended.
  • the photoelectric scanning device is preferably a DX code reader, since in this case the information contained in a DX code to the side of the copy originals can be used to carry out the method according to the invention.
  • the pair of feed rollers and possibly the further pairs of feed rollers can be driven in the feed direction and in the opposite direction, in order in this way to eject film strips that are not required or have not been correctly entered in the direction of insertion.
  • a switch and further film transport means can be provided in relation to the feed direction of the film strips behind the photoelectric scanning device but in front of the deflection roller pair in the transport path of the film strips, which are controlled by the computer unit and can be activated if necessary if a film strip is to be separated. In this way, a filmstrip can be removed from the preparation station in an alternative way.
  • the cut film strips usually have between four and six full-format 35mm copies or a correspondingly higher number of half-format copies.
  • the procedure for all lengths of film strip that usually occur is when the distance of the first photoelectric sensor from the pair of feed rollers is approximately from 10 mm to 20 mm and a second and possibly a third photoelectric sensor each at a distance of approximately 30 mm to approximately 80 mm from the previous sensor are arranged.
  • the distance of the photoelectric scanning unit from the pair of feed rollers is preferably from about 10 mm to about 30 mm.
  • a preparation station for film strips is provided with the reference number 1 as a whole.
  • Such devices are used in large laboratories, where individual cut film strips of a reordering order with usually 4 to 6 copy templates, usually negative templates, are glued to a carrier tape and are then wound onto a film spool. This spool with the film strips glued to the carrier tape is plugged in at the beginning of a photographic copier, then the customer order is processed largely automatically according to the order data.
  • the device has a housing 2 in which various electronic, electrical and mechanical device components, for example drive means for film transport devices etc., are accommodated.
  • a work table 3 extends horizontally over the length of the housing 2 and serves as a work surface for the operating personnel.
  • the carrier tape 77 consists of an adhesive tape 7 and a paper tape 70, which are glued together in such a way that the outermost longitudinal edge of the film strips lies between the two tapes and is glued to the adhesive tape 7.
  • the adhesive tape 7 is from an unwind spool 6, which can be plugged in above the work table 3 on the front of the housing.
  • a second unwinding spool 14 with the paper tape 70 is arranged below the worktop 3 and is fed to the gluing station 5.
  • the tapes glued together in the gluing station 5 to form the carrier tape 77 are wound onto a take-up spool 8 which can be plugged onto the front of the housing.
  • Illumination surfaces 9 are let into the work table 3, which allow the operating personnel to look at the copy templates on the film strip.
  • a keyboard 11 integrated in the worktop is connected to a computer unit 10 housed in the housing 2.
  • the customer-specific order data and any correction values can be entered into the computer unit 10 via these.
  • the computer unit has a display device 12, via which the information entered via the keyboard 11 can be checked by the operating personnel.
  • the display device 12 can optionally also display messages and information, for example error messages.
  • the display device 12 is a display or a screen.
  • the data entered by the operating personnel are stored on a storage medium 13 which is compatible with the subsequent processing stations.
  • magnetic tape cassettes or computer disks are used as the storage medium. In this way, all the reordering data associated with the film strips wound on the film reel 8 are stored on a magnetic tape or a computer diskette and can then be forwarded together with the film reel to the subsequent processing stations.
  • the area of the preparation station 1 which is essential to the invention essentially comprises the input area 4 for the film strips up to the gluing station 5. This area is shown in FIGS. 2 and 3 in side or in elevation.
  • the input area 4 has a pair of feed rollers 41, 42 and possibly also further pairs of transport rollers 43, 44 and 45, 46, respectively, which can be driven by a motor 40. Only one roller is driven at a time, while the second forms a counter roller. In the present exemplary embodiment, the rollers with the odd-numbered reference numbers 41, 43, 45 can be driven, while those with the even reference numbers 42, 44 46 represent the counter-rollers.
  • a rotation detector 47 monitors the counter roller 42 of the feed roller pair 41, 42 and is connected to the computer unit 10.
  • the rotation detector 47 is an angle encoder; in this way it is not only possible to detect whether the counter roller 42 turns, but also the revolutions over the measured angle can be counted. It is advantageous to arrange the rotation detector 47 at the counter roller 42, since it rolls exactly on the incoming film strip F.
  • the angle information of the rotation detector 47 can be converted into length units in the computer unit, which the film strip F is advanced by the feed roller pair 41, 42.
  • the film strip entered is transported along the transport plane T between the pairs of rollers.
  • the transport direction D runs from left to right, from the pair of feed rollers 41, 42 to a pair of deflection rollers 71, 72 in the gluing station 5.
  • the tape 7 and the paper tape 70 are guided over the deflection rollers 71, 72.
  • the adhesive tape is adhered to its outermost longitudinal edge and to the paper tape 70, and in this way the film strip F is connected to the carrier tape 77.
  • three photoelectric sensors are arranged, which are connected to the computer unit 10 via signal lines (not shown). Counted from the feed roller pair 41, 42, these are a first 49, a second 50 and a third sensor 51.
  • the distance of the first photoelectric sensor 49 from the feed roller pair 41, 42 is approximately from 10 mm to 20 mm.
  • the second and third sensors 50 and 51 are each spaced from about 30 mm to about 80 mm from the respective previous sensors 49 and 50, respectively.
  • the arrangement of the sensors 49-51 parallel to the transport direction D is the film strip F.
  • the signals from the first sensor 49 can also be used to control the drive motor 40 for the feed roller pair 41, 42 and the further transport roller pairs 43, 44 and 45, 46. It goes without saying that the drive motor for the feed roller pair 41, 42 and for the further transport roller pairs 43, 44 and 45, 46 can also be controlled in another way.
  • the rotation detector 47 on the counter roller 42 of the feed roller pair 41, 42 can also be used for this purpose. When the leading leading edge of the filmstrip F enters the nip between the driven roller 41 and the counter roller 42, the counter roller 42 is rotated. The rotational movement is detected and the drive motor 40 is activated as a result.
  • the photoelectric sensors 49-51 serve to detect the rear end of the inserted film strip F. From the detection of the rear end of the film strip F. and the angle information of the rotation detector 47, the length of the input film strip F is determined in the computer unit 10. This is done simply by adding the feed distance determined from the angle information and the distance of the sensor, which has determined the rear end of the film strip F, from the feed roller pair 41, 42. In principle, two sensors are sufficient to check the correct position of an input film strip F, but, as shown, preferably three photoelectric sensors 49-51 are provided, since film strips F of different lengths can be measured in this way without the distance existing in known preparation stations to have to change between the feed roller pair 41, 42 and the deflection roller pair 71, 72. This has the advantage that existing devices can also be retrofitted in order to be suitable for using the method according to the invention.
  • a photoelectric scanning device 48 Arranged behind the pair of feed rollers 41, 42 (based on the transport direction D of the film strip F) is a photoelectric scanning device 48, which is connected to the computer unit 10 via a signal line (not shown). With the aid of this scanning device 48, the numbers of the original copies N on the film strip F being transported past as well as a lateral offset of the film strip F are determined, for example by angled input. This is done simply by determining whether the number can be read at all. In addition, the scanner 48 can also determine the correct position of the layer side of the film strip F.
  • the scanning device 48 is preferably a DX code reader which scans the DX code arranged on the film strip F to the side of each copy original N. In this way, the master number contained in the DX code can be determined.
  • the DX codes are very narrow, so that a lateral offset of the film strip F results in incomplete detection of the code by the DX code reader 48.
  • each DX code has a start sequence and a stop sequence. Depending on whether a start sequence or a stop sequence is present first on the DX code reader 48, it is thus determined whether the copy master numbers on the film strip F are in ascending or descending order; it can also be used in this way to determine whether the layer side of the film strip F is in the correct position. For these investigations, it is generally sufficient to read the first DX code located on the film strip F. Only in the event that this first DX code cannot be read, for example because it has been destroyed, the next one readable DX code.
  • the master copies N on the film strip F can be clearly identified.
  • This information only has to be transmitted to the computer unit 10 in the case of semi-format copy templates N. This can be done manually by input via the keyboard 11, or with the aid of a sensor which detects the webs between the original copies N. The spacing of the webs can then be used to infer the format of the copy templates on the film strip.
  • the sensor can additionally be provided in front of the pair of feed rollers 41, 42, but for example the first sensor 49 or the DX code reader 48 can also be designed for this purpose.
  • the determined copy master numbers on the attached film strip F are compared with the customer information entered into the computer unit 10 and a decision is then made as to whether the film strip in question is necessary for the processing of the reordering order and should be glued to the carrier tape 77 or whether it should be removed from the device .
  • the pair of feed rollers 41, 42 and the pair of transport rollers 43, 44 and 45, 46 can also be driven counter to the direction of feed D. If a film strip F is then to be ejected, the computer unit 10 sends a corresponding signal to the drive motor 40 for the pair of feed rollers 41, 42 and the further pairs of transport rollers 43, 44 and 45, 46, respectively. The motor rotates in the opposite direction, the direction of rotation of the roller pairs reverses accordingly, and the film strip F is ejected again in the opposite direction to the feed direction D.
  • a switch and further transport means for a film strip F which are controlled by the computer unit 10, can be provided between the second pair of transport rollers 45, 46 and the deflection roller pair 71, 72 of the adhesive station 5.
  • a switch is described in EP-A-0,554,639, which is hereby declared to be an integral part of this description.
  • the switch and the other means of transport are activated if necessary if a film strip F is to be eliminated. In this case, the film strip is not ejected again against the feed direction, but rather is transported to an output area arranged above or below or to the side of the input area 4.
  • the most common operating errors can be compensated for by the operating personnel without major interruptions to the workflow.
  • the staff no longer has to take care that the film strips are always entered in a chosen orientation (negative number sequence ascending or descending).
  • Film strips incorrectly entered with regard to the position of their layer side are also reliably recognized and the operating personnel are made aware of this.
  • Film strips incorrectly entered and unnecessary for the processing of a reordering order are not adhered to the carrier tape. This eliminates time-consuming repair work and avoids major gaps that can lead to malfunctions in the subsequent processing stations.
  • the film strips which are wound on a film spool and glued to the carrier tape, are always in the correct position and productivity losses due to unnecessary film strips are avoided.
  • the proposed changes in equipment are also for retrofitting existing preparation stations suitable to be able to work with them according to the inventive method.
