Definitions

  • the invention relates to a method for loading a Processing machine with flat products, such as printed sheets, Cards, samples or the like according to the preamble of the claim 1.
  • the single unwinding station which is characterized by the inclusion of a roll, is less expensive and takes up less space, but makes it necessary to interrupt the processing machine or the saddle stitcher if an empty roll core has to be replaced by a new roll.
  • the processing machine can therefore not be used optimally and the processing suffers a certain unproductivity.
  • the double unwinding station avoids this disadvantage in that when a winder runs empty, the winder prepared next door can be switched on immediately via a switch.
  • a separate product memory is assigned to the conveyor line, which picks up products from the conveyor line and, if the product supply is interrupted, feeds the previously stored products to the conveyor line.
  • the conveyor line consists of partial conveyors, the former of which is driven at a constant, higher speed than the downstream conveyor, which also has a constant speed in order to shed the products more closely. set up.
  • US 5,088,711 relates to a collating machine with several Investors arranged along a conveyor are.
  • the feeders point over a deduction device a magazine in which the printed products are stacked are.

  • FIG. 1 and 2 show a device 1 according to the invention for loading a processing machine 2.
  • the latter is, for example, a collating machine from which a stack magazine 4 belonging to a known feeder 3 and loaded with printed sheets 6 and a channel-like collecting device 5 can be seen.
  • the printed sheets 6 are provided for processing in a storage device designed as a winding 12 and — as can be seen — on the way to the processing machine 2.
  • the winding 12 has a core 7 which is rotatably supported in a stand 8.
  • the layers wound around the core 7, the printed sheets 6 occurring in a scale formation, are held on the core 7 by winding tapes 9, one end of a winding tape 9 being fastened to the core 7 and the other to a roller 11 mounted in a tape magazine 10 , Contrary to the illustration in FIG. 1, the band magazine 10 is fastened to the frame 8 and the roller 11 is coupled to the output shaft of a geared motor M R in coordination with the winding 12.
  • Processing machine 2 and winding 12 are connected by a conveying device 13 so that when the scaled sheets 6 are unwound from the winding 12, which can be driven over the circumference of the winding core 7 or, as illustrated, with its conveyor belt 19 over its circumference, the latter onto the first one in the conveying direction Conveying element 14, the conveying elements 14 to 18 forming the conveying device 13 arrive.
  • the conveyor belts 19 to 21 usually used for direct loading of a processing machine 2 are provided, of which the first 19 in the conveying direction is applied to the circumference of the winding by means of a lifting element 23 acting on an arm 22.
  • the winding is emptied via the driven conveyor belt 19 to the subsequent conveyor belts 20, 21, which are articulated on the arm 22, in such a way that an undisturbed conveying flow can occur.
  • the arm 22 in turn is pivotally mounted on a stand 23.
  • a sensor F 8 gives a signal when the arm 22 is raised to such an extent that the supply on the roll has been removed except for a remaining stock.
  • the product memory shown consists of five memory sections connected in series, respectively.
  • the conveyor elements 14 to 17 are each formed by two laterally offset endless belts 24, 25 and a deflection roller 26 and a plurality of deflection rollers 27, around which the belts form a support for the printed sheets 6.
  • the conveying elements 14 to 17 of the exemplary embodiment shown each have a longer flat section and an adjoining approximately circularly curved section on which the printed sheets 6 are transported, the flat section being guided by two deflecting rollers 27, 27 'and the undershot area of the deflecting roller 26 is formed.
  • the upward circular section on which the printed sheets 6 are transported is determined inwardly by the deflecting roller 26 and outwardly by the circumferential belts 24, 25, the latter subsequently forming the conveying end on the flat section of the conveying element 14 a guide roller 28 and a deflecting roller 27 return to the deflecting roller 27 '.
  • the flat section of the second conveying element 15 adjoins the conveying end of the conveying element 14.
  • the conveying end of the conveying device 13 forms the flat conveying element 18, which is formed from two spaced apart belts 24, 25 which run around deflection rollers 27.
  • a conveyor belt 29 is provided as a transition from the conveyor device 13 to the stack magazine 4, with which the incoming printed sheets 6 are taken over by an acceleration device 30.
  • Conveyor belt 29 is also driven by a separate motor M B.
  • the conveying elements 14 to 18 can be driven by electric motors M 1 to M 5 which can be controlled individually or in association with a plurality of conveying elements 14 to 18 and which act on a deflecting roller 26 or deflecting roller 27 of a conveying element 14 to 18.
  • One of the deflecting rollers 27 of a conveying element 14 to 17 receiving the belts 24, 25 is advantageously resiliently supported, so that shingled streams of different thicknesses can pass through the curved sections of the conveying elements 14 to 17.
  • Fig. 2 are further, the exemplary embodiment according to Fig. 1 entered additional information and then described.
  • a sensor F 1 to F 6 is arranged at the upstream end of a conveying element 14 to 18.
  • An additional analog sensor F 7 is arranged in the machine 2. It controls the motors M 1 to M 5 and M R in such a way that in normal operation the winding belt 9, all the conveyor belts 19 to 21 and the conveyor elements 14 to 18 and the conveyor belt 29 have the same speed and run so fast that the machine 2 delivers the one supplied Scale 31 resp. can reliably process the product flow.
  • FIG. 7 shows an embodiment of the control device 40 with which the motors M are controlled.
  • Sensor F 7 controls a first frequency converter FU 1 , the frequency of which drives all motors M 1 -M 5 , M R , M B in normal operation.
  • the signal from the sensor is also connected to two further frequency converters FU R and FU 2 via two multipliers 41, 42, which multiply this signal by an adjustable factor.
  • the frequency of these converters is, for example, a factor 5 higher than the frequency of the converter FU 1 .
  • the motors M R , M B and M 1 -M 4 are in function of the signals from the sensors, F 1 -F 8 and a start signal via a circuit 44-49 either with the frequency of the converter FU 1 or with the frequency of one of the FU R or FU 2 powered.
  • FIG. 3 shows normal operation in which all tapes run at the same speed and controlled by the sensor F 7 .
  • Circuits 44-49 connect all motors M to the converter FU 1 .
  • the scale 31 is the same thickness everywhere.
  • FIG. 4 shows the situation shortly before the end of the product supply on the winding core 7. To prepare for a winding change, sensor F 8 has responded and switched the circuit 44 so that the motor M R and with it the motors of the belts 19 to 21 with, for example, the run five times the speed of the other belts.
  • a thicker scale 31 is formed than has previously occurred in normal operation.
  • all conveyor elements 14 to 18 are filled with the thick scale 31 'when the winding core 7 is empty, as shown in FIG. 5.
  • the sensor F 1 determines the end of the scale 31 ', switches off the motor M R via the circuit 44 and initiates the winding change.
  • the sensor F 2 -F 5 When the end of the thick scale 31 'passes the sensor F 2 -F 5 at the downstream end of the conveying elements 14 to 17, the sensor F 2 -F 5 successively switch on the relevant motors M 1 -M 4 via the circuits 45-48 the higher frequency of the converter FU 2 .
  • the motor M R is connected to the converter FU R by a start signal on the circuit 44.
  • the belts 9 and 19 to 21 thus run at a higher speed than at least the last conveyor element 18.
  • a logic circuit 50 in which the signals F 1 -F 6 are linked, all circuits 44-48 are reset to their basic position via a reset input R as soon as the new, thin scale 31 runs onto a conveying element 14 to 18, in which the thick scale 31 'still runs.
  • This logic condition is such that the circuit 50 supplies a reset signal if one of the sensors F 1 -F 4 is switched off by the arrival of the new scale 31 before the next sensor F 2 -F 5 is switched on by the departure of the thick scale 31 ' has been.
  • the new thin scale 9 then follows the expiring old one just a small gap which is usually less than that Length of a conveyor element is 14 to 18. This ensures that the processing machine 2 when changing the winding can be operated practically without interruption.
  • the Conveyor 13 or the product memory is low Requires space and, above all, does not require any width additional space so that it fits well in existing facilities limited space can be integrated.
  • the sensor F 6 can also be designed such that it can not only discriminate between thin and thick scale 31, 31 'or between thick scale 31' and zero, but also between thin scale 31 and zero.
  • the control device 40 according to FIG. 7 can be modified such that the last conveying element 18 can also be switched between the two speeds. It is possible to switch all motors except M B to converter FU 2 again as soon as the end of thick scale 31 'has passed sensor F 6 . The motors M 1 -M 5 and M R are then switched back to the converter FU 1 when the beginning of the new scale 31 reaches the sensor F 6 . As a result, the interruption of the product flow to the machine 31 when changing the winding or in another supply interruption can be kept extremely short.
