Definitions

  • the invention relates to a feeder for sheet-fed rotary printing presses with drawing marks which are coupled to the machine drive and impart a drawing movement to each incoming sheet, furthermore with a device for checking the correct lateral sheet installation and for interrupting the sheet feed in the event of a defective sheet installation.
  • Known embodiments of the above-mentioned invention are single sheet or scale feeders. Alignment of a sheet, which is a prerequisite for precise printing, takes place during transport over the feed table in two directions, namely the front alignment and the lateral alignment. Several front marks ensure that the leading edge of the sheet is held securely. Lateral alignment is usually done using drawing marks.
  • Draw marks on sheet-fed printing machines have the task of precisely aligning the sheet arriving from the feeder by pulling from the side. This alignment has to be carried out with extreme precision, since misalignments can cause color differences between the specimens.
  • Sheet printing machines with draw marks are known from the document DE-OS 30 11 626 Al.
  • the sheet to be aligned is pressed onto the suction openings in the sliding plate using a swab roller.
  • the vacuum supporting the acceleration process can have a temporally defined effect, so that the high static friction when the sheet is retired is overcome and the sheet is prevented from being compressed at the stop by switching off the suction air.
  • a device is described which achieves the desired system accuracy without using drawing marks.
  • a measuring head with two photo sensors is attached to the side of the feed plate, and the determined side difference serves as a guideline for the lateral displacement of the gripper drum.
  • the lateral displacement of the gripper drum is mechanically and technically difficult and does not always lead to a system that is tailored to the customer.
  • the use of two photo sensors is very complex.
  • the object of the invention is to use simple means to monitor both the correct drawing end position and the drawing process, and to shorten the set-up times and downtimes of the sheet-fed rotary printing machines.
  • this is achieved in that a sensor for checking the correct sheet entry and the lateral contact of the sheet is arranged on at least one side edge of the feeder, and that this sensor supplies signals which are processed by digital control electronics and thus influence the machine control.
  • Another embodiment of the invention is that the sensor is arranged so that the sheet before the pulling movement is initially outside, but at the end of the pulling movement of the drawing mark within the response range of the sensor, and that the control electronics give the appropriate message.
  • One embodiment of the invention is that an error message from the control electronics occurs if a sheet is in the response range of the sensor before the drawing process.
  • control electronics on the signal sequence supplied by the sensors in the response range of which the sheet assumes its two target positions before and after drawing, recognizes the assignment of one of the sensors to the direction of movement of the drawing marks in the event of a change in drawing direction and only thereafter still issues an error message due to signal sequences from this sensor.
  • the sensors can either consist of reflex sensors or light barriers or reflex light barriers. They can also be capacitive or pneumatic sensors.
  • control electronics are coupled to a light-emitting diode display field with the respective operating states and light-emitting diodes representing the fault displays.
  • the digital control electronics are designed in such a way that they deliver the signals supplied by the sensors via the target position of the sheet via a buffer and a read-only memory to the LED display field and, in the event of incorrect sheet positions, trigger an alarm, optically or acoustically, or affect the machine control.
  • Another advantage of the invention is that the sensors are independent of the direction of travel, i.e. are functionally and structurally designed so that they are equally suitable for both directions.
  • the device according to the invention thus enables better monitoring and alignment of the sheet feed.
  • the automatic detection of the drawing direction uses the sensors to change the drawing direction without additional work. Without this automatic change in the direction of pull, it would be necessary to switch the control or remove the unused sensor from the work area or to convert the sensor to the other side.
  • the sheets 8 to be printed are fed from a sheet feeder 12 via the feed table 2 to the feed drum 13 of a first printing unit 14.
  • the printing unit 14 comprises a plate cylinder 21, blanket cylinder 16 and a printing cylinder 15.
  • the transfer takes place via transport cylinders 17 and a transfer drum 18 located between them to a further printing unit 19.
  • the printing unit 19 in turn comprises one Plate cylinder 21, blanket cylinder 16 and an impression cylinder 22.
  • the sheet is deposited on a delivery stack 4 with the aid of a chain sheet delivery arm 20.
  • a slot initiator 23 is provided with the arc control elements designed as reflex sensors 7. consisting of a query switch 10 and a query disc 11, coupled via control electronics.
  • the query disc 11 of the slot initiator 23 is mounted on a single-speed shaft, not shown.
  • the interrogation disk 11, which is controlled by the machine cycle, can take up two interrogation times, namely a and b.
  • the query disk 11 of the slot initiator 23 shown in FIG. 3 is located at the query time a. This means that the sheet 8 already abuts the front marks 6, as shown in FIG. 2, but the sheet 8 has not yet been drawn from the pull mark 9 to the side mark 24.
  • the sheet 8 is now drawn from the drawing mark 9, for example to the left, to the side mark 24.
  • the query disc 11 of the slot initiator 23 reaches the query time b, as shown in FIG. 5.
  • the sheet 8 is in the response area of the reflex button 7 and on the side mark 24 of the drawing mark 9, as shown in FIG.
  • FIG. 6 shows the schematic sequence of the drawing mark control.
  • the control electronics When the power supply is switched on and the sheet-fed printing press 1 is running, the control electronics, together with the two reflex buttons 7, recognizes on the basis of the signal sequence of the interrogation switch 10 whether the pulling process has ended. In accordance with the signal sequence stored in the control electronics, the control electronics automatically decide the direction of pull, either "right” or "left".
  • control electronics After the control electronics have recognized on the basis of the supplied signal sequence that after e.g. has been pulled to the left, this is shown in the light-emitting diode display field 33, which is clearly visible to the printer on a sheet metal wall between sheet feeder 12 and printing unit 14 of the sheet-fed printing press.
  • control electronics issues an error message which is displayed in the light-emitting diode display field 33.
  • control electronics monitor whether the pulling direction has changed due to the signal sequence on the reflex buttons 7. If the change is not made, there is clearly a pulling error, which is also displayed in the LED display field 33.
  • control electronics automatically monitors the pulling process "on the right", and the display in the LED display field 33 is displayed again as on the left side, repeat with every new incoming sheet.
  • a machine cycle 25 by which the time period for the acquisition of the actual values by the comparison device and the forwarding of the signals to the LED display field 33 is controlled, also reflex sensors 26 and 27 are shown, which are connected via amplifiers 28 to the Inputs of the buffer 29 are connected, the inputs and outputs of which are symbolically combined, and the outputs of the buffer 29 lead to the inputs of a read-only memory 30, the outputs of which in part lead to a light-emitting diode display field 33 and to an acoustic error reporting device 32, which is not shown in detail , and the other part are fed back to the inputs of the buffer 29.
  • the control electronics are designed so that they query the state of the reflex sensors 26, 27 twice during a machine cycle 25.
  • the first The time of inquiry is before the drawing process.
  • the state of the reflex sensors 26, 27 is passed on via the amplifier 28 to the buffer store 29, which forwards this information into an EPROM, a programmable read-only memory 30.
  • the read-only memory 30 is programmed so that it still waits for the status message of the second query, which consists of whether or not the sheet has reached the characteristic target position after being drawn.
  • the read-only memory 30 If the read-only memory 30 has stored all the information necessary for a machine cycle 25, it outputs digital values according to its programming to the LED display field 33, which reproduces the signal sequence of the respective operating state, or to the error reporting device 32, which consist of acoustic signal transmitters.
  • the light-emitting diode display field 33 in FIG. 8 consists of the display elements 34 to 45, which light up accordingly in the respective operating states. Specifically, the display elements 34 to 45 are shown in three rows, namely the three light-emitting diodes 34, 35, 36 are in one row. The light-emitting diodes 34, 35 are yellow-lighted display elements for the right and left reflex light sensors. The yellow light-emitting diode 36 indicates the state of the slot initiator 23. In the next row, the respective drawing processes are indicated by the informative symbol light fields 40, 41, 42, 43, 44, 45. The yellow symbol illuminated fields 40, 43 correspond to the lateral arrangement.
  • the symbol illuminated fields 44 and 41 light up green for the right and left side, respectively.
  • the symbol illuminated fields 42 and 45 signal the error in red.
  • the green light-emitting diodes 37, 39 indicate whether the sheet has come into contact correctly and the incorrect installation signals the light-emitting diode 38.
