Definitions

  • the invention relates to a device and a method for automated loading of processing stations with printing cylinders.
  • Printing cylinders for rotary printing presses are different in the production Machining stations fed where, for example, a chrome or copper plating preserved or polished.
  • automatic lines known from US-A-5,336,898, where the manufacturing steps are largely automated according to a specific work program expire.
  • the centering device centers the pressure cylinder on a so-called centerline, which forms the centering line for all processing stations.
  • the operator has the option of the necessary manufacturing data such as cylinder dimensions and enter the desired work programs. Then drives a crane enters the entry area.
  • the crane transports the printing cylinder from the processing station to a storage location where the printing cylinder is stored until the operator retrieves it.
  • the The operator first uses the control to determine the storage location of the desired cylinder and then give the command to outsource. Then he usually has to wait with the identical output slot until the crane processes the processed one Has picked up the printing cylinder from the storage location and dropped it at the delivery location.
  • the system described thus has the disadvantage that, on the one hand, a waiting time of When inserting the impression cylinder into the automatic line, the operator is asked until the Crane has picked up the printing cylinder and, on the other hand, another waiting time is required until the crane returns the pressure cylinder from the system to the trolley spent. Depending on the operating conditions of the system, these waiting times may vary be quite substantial.
  • the invention has for its object a device of the type described to improve that unnecessary waiting times for the operator can be avoided.
  • a device for loading at least one processing station with at least one pressure cylinder, with several stationary charging stations, the each as an input place for introducing the printing cylinder into the device, as Storage location for storing the printing cylinder before and after processing and as a delivery location for ejecting the impression cylinder from the device after processing are formed, and with a conveyor for conveying the printing cylinder between one of the charging stations and the at least one processing station is thereby characterized in that the charging stations each for receiving a transport device are formed, on which transport device the printing cylinder for transport is releasably attached outside the device.
  • the transport device can be, for example, a cylinder transport carriage act.
  • the operator is thus able to assemble the printing cylinder to be processed can be inserted into any input position with the transport device and enter the required manufacturing data. Then the operator can leave the entry area because the conveyor fetches the pressure cylinder, as soon as the corresponding system capacity is available. After finishing editing the pressure cylinder is returned to the same location by the conveyor and deposited in the transport device.
  • the printing cylinder can stay there for so long be stored until the operator picks it up together with the transport device.
  • the charging stations each have a positioning device for positioning and fixing the transport device. This can ensure be that the transport device in the charging station a defined position occupies and is held in this position. This is especially necessary because the output of the finished printing cylinder on the transport device automatically takes place and requires an exact position of the transport device.
  • the positioning device a braking device based on a magnetic principle.
  • the transport device for example the cylinder transport carriage, becomes a magnet held in the desired position.
  • the conveying device is preferably a crane device that moves in the axial direction of the printing cylinder has a movable transverse offset or a crossmember on which a Bracket for holding the printing cylinder at both ends relative to the transverse offset is provided movably in the axial direction of the printing cylinder.
  • the bracket points two holding elements movable relative to one another and relative to the transverse offset. Thereby it is possible to first contact one of the holding elements with the one to be held by the latter Bring side of the impression cylinder. The transverse offset then moves and the other holding element in the direction of the first holding element until the other holding element comes into contact with another side of the impression cylinder.
  • the pressure cylinder to be machined is then held and can by the Transport device can be lifted off.
  • the speeds at which the Cross offset and the other holding element move are chosen so that the other Holding element moves relative to the transverse offset at the same speed as the transverse offset moves relative to the first holding element. This ensures that the pressure cylinder is symmetrical to the traverse when it is lifted from the transport device stands.
  • the two holding elements consequently move towards one another at a certain speed, while the transverse offset is heading at the same speed of the holding element already in contact with the pressure cylinder. This leads to the holding element in contact with the printing cylinder does not lose contact with the printing cylinder, but stands still relative to the cylinder.
  • a is on the crane device Device for determining at least one dimension of the printing cylinder is provided.
  • the dimensions can also be Bale length or the total length of the cylinder.
  • a charging station address, cylinder data and a work program for the printing cylinder to be machined can be entered.
  • the method according to the invention enables the method of operation already described above, after which the printing cylinder can be retracted into any charging station and is transported there from the conveyor to the processing station. After completion The processing and return transport to the loading station becomes the printing cylinder deposited on the transport device, whereupon this is released and from the System can be moved out.
  • printing cylinders can be processed and can be dealt with at the same time, since the operator has more regardless of the crane performance Introduce printing cylinders on transport devices into or from the device can see.
  • the conveyor after the Printing cylinder on the transport device to the format of the next to be transported Pressure cylinder adjusts. This means that the holding device is already on the can set the next printing cylinder format even before the conveyor to do so has reached the necessary position.

  • the trolley 10 When introducing the printing cylinder 9 together with its transport carriage 10 into the System, the trolley 10 must be pushed into the charging station 2 until the cylinder axis rests against a stationary stop 11. This applies regardless of the Length of the cylinder 9 and its location on the trolley 10, so that in any case a defined relative position of the printing cylinder 9 is fixed in the charging station 2.
  • the Stop 11 can be formed, for example, by a pressure-sensitive sensor, which responds to contact through the cylinder axis.
  • the cylinder axis touches the stop 11, it becomes an automatic one, not shown in the figure Braking device activated (for example a magnet) that the carriage 10 in its Holds position until the printing cylinder 9 is back on the trolley after processing 10 is filed.
