Definitions
- the invention relates to a device and a method for the automated loading of processing stations with printing cylinders.
- Printing cylinders for rotary printing presses are fed to various processing stations during production, where they are given a chrome or copper coating, for example, or polished.
- so-called automatic lines are known, in which the production steps are largely automated according to a specific work program.
- the pressure cylinders are usually inserted into cylinder transport carriages and pushed manually into an input station with a centering device.
- the centering device centers the printing cylinder on a so-called centerline, which forms the centering line for all processing stations.
- the operator has the option of entering the necessary manufacturing data, such as cylinder dimensions and the desired work programs.
- a crane then moves to the input location, centers a suitable holder with the journal of the printing cylinder or the barrel of the printing cylinder, lifts the printing cylinder from the transport carriage and transports it either directly to a first processing station or to a storage location where the printing cylinder is so stored for a long time until the corresponding processing station has become free.
- the crane transports the printing cylinder from the processing station to a storage location, where the printing cylinder is stored until the operator calls it up.
- the operator To output a cylinder from the automatic line, the operator must first determine the storage location of the desired cylinder via the control and then give the command to outsource. He then has to wait at a delivery location, which is usually identical to the input location, until the crane has picked up the processed printing cylinder from the storage location and set it down at the output location.
- the system described thus has the disadvantage that, on the one hand, a waiting time is required from the operator when the printing cylinder is introduced into the automatic line until the crane has picked up the printing cylinder, and, on the other hand, a further waiting time is required until the crane removes the printing cylinder from the System has returned to the trolley. Depending on the operating conditions of the system, these waiting times can be quite considerable.
- the invention has for its object to improve a device of the type described so that unnecessary waiting times for the operator can be avoided.
- a device for loading at least one processing station with at least one printing cylinder is characterized by a plurality of charging stations, each as an input location for introducing the printing cylinder into the device, as a storage location for storing the printing cylinder before and after processing and as an output location for outputting the Printing cylinders are formed from the device after processing; and by a conveying device for conveying the printing cylinder between the loading stations and the processing station.
- the charging stations are each designed to accommodate a transport device, on which a pressure cylinder for transport outside the device is detachably fastened.
- the transport device can be, for example, a cylinder transport carriage. The operator is thus able to push the printing cylinder to be machined together with the transport device into any input location and to enter the production data required accordingly. The operator can then leave the input station because the conveyor fetches the printing cylinder as soon as the corresponding system capacity is available. After the processing has been completed, the printing cylinder is returned to the same location by the conveyor device and placed in the transport device. The printing cylinder can be stored there 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 that the transport device assumes a defined position in the charging station and is held in this position. This is especially necessary because the finished printing cylinder is automatically output on the transport device and requires an exact position of the transport device.
- the positioning device has a braking device which is based on a magnetic principle.
- the transport device for example the cylinder transport carriage, is held in the desired position with the aid of a magnet.
- the conveying device is preferably a crane device which has a transverse offset or a traverse which is movable in the axial direction of the printing cylinder and on which a holder for holding the printing cylinder is provided at its two ends so as to be movable relative to the transverse displacement in the axial direction of the printing cylinder.
- the holder has two holding elements that are movable relative to one another and relative to the transverse offset. This makes it possible to first bring one of the holding elements into contact with the side of the printing cylinder to be held by the latter. The transverse offset and the other holding element then move in the direction of the first holding element until the other holding element comes into contact with another side of the printing cylinder.
- the pressure cylinder to be processed is then held and can be lifted off the transport device.
- the speeds at which the transverse offset and the other retaining element move are selected such that the other retaining element moves relative to the transverse offset at the same speed as the transverse offset moves relative to the first retaining element. This ensures that the pressure cylinder is symmetrical to the crossbar when it is lifted off the transport device.
- the two holding elements consequently move towards one another at a certain speed, while the transverse offset moves at the same speed in the direction of the holding element already resting on the pressure cylinder.
- the result of this is that the holding element which is in contact with the printing cylinder does not lose contact with the printing cylinder, but rather stands still relative to the cylinder.
- a device for determining at least one dimension of the pressure cylinder is provided on the crane device.
- a device can be, for example, a device described in DE 42 24 253.
- the dimensions can also relate to the 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 processed can be entered via a control.
- a method according to the invention for loading at least one processing station with at least one printing cylinder has the following steps:
- Provision of several charging stations each serving as an input location, as a storage location and as an output location for the printing cylinder;
- the method according to the invention enables the method of operation already described above, according to which the printing cylinder can be moved into any charging station and is transported there from the conveyor to the processing station. After completion of the processing and return transport to the loading station, the printing cylinder is placed on the transport device, whereupon it is released and can be moved out of the system.
- printing cylinders can be processed and treated at the same time in this method, since the operator can insert further printing cylinders into the device on transport devices or remove them from the device independently of the crane performance.
- the conveying device adjusts itself to the format of the next printing cylinder to be transported after the printing cylinder has been placed on the transport device. This means that the holding device can adjust itself to the next printing cylinder format even before the conveying device has reached the required position.
- Figure 1 is a plan view of the device according to the invention.
- FIGS. 2 to 10 side views of the device with different steps to explain the inventive method when loading a processing station with a printing cylinder.
- FIG. 1 shows a plan view of a device according to the invention in the form of an automatic line with a plurality of processing stations 1 and a plurality of loading stations 2 arranged on a center line 1 a.
- FIGS. 2 to 10 show side views of the device, seen in the direction of the arrow X in FIG. 1.
- the processing stations 1 can be conventional galvanizing baths, degreasing stations or polishing machines, etc.
- a crane 3, recognizable in FIG. 2, can be moved on rails 4 in the direction of arrow 5 over the entire system.
- the crane 3 carries a transverse offset 7 which can be moved back and forth in the direction of the arrow 6 and to which a clamping system 8 serving as a holding device for the pressure cylinder is fastened by means of a cross member 7a.
- the charging stations 2 are arranged side by side in the number suitable for the system. They serve at the same time as an input location for introducing the printing cylinders 9 to be processed into the device, as a storage location for storing the printing cylinders 9 before and after processing and as an output location for outputting the printing cylinders 9 from the device. In FIG. 1, some charging stations 2 are free, while in other charging stations 2 pressure cylinders 9 with partially different sizes are already used.
- the charging stations 2 can also be arranged in an extension of the axis of the processing stations 1 (above the processing stations 1 in FIG. 1).
- the pressure cylinders 9 can be axle cylinders, as shown in the figures. Alternatively, hollow cylinders can also be used. In this case, the centering devices and the holding device must be modified accordingly.
- the pressure cylinders 9 are held on transport carriages or cylinder carriages 10, for example, which can be seen in FIG. 3, and can be moved back and forth by the operators in the factory.
- the transport carriage 10 When introducing the printing cylinder 9 together with its transport carriage 10 into the system, the transport carriage 10 has to be pushed into the charging station 2 until the cylinder axis bears against a stationary stop 11. This applies regardless of the length of the cylinder 9 and its position on the transport carriage 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.
- an automatic braking device (not shown in the figure) which holds the carriage 10 in its position until the printing cylinder 9 is placed on the transport carriage 10 again after it has been processed.
- FIG. 2 shows the starting position. Since the components of the device which are identical to FIG. 1 are identified by the same reference numerals, the elements are not described again.
- the clamping system 8 has two clamping jaws 8a and 8b, which can be moved back and forth in the direction of the arrow 6 relative to the transverse offset 7.
- a device 12 for example in FIG. 3, for automatically determining the diameter of a printing cylinder by means of a light barrier movable relative to the printing cylinder 9 is arranged on the clamping system 8.
- the transverse offset 7 on the crane 3 moves into a position above the pressure cylinder 9.
- the crossbeam 7a and thus the clamping system 8 are lowered so far that the clamping jaws 8a and 8b lie at the level of the cylinder axis.
- the clamping jaws 8a, 8b in FIG. 6 are moved together until the left clamping jaw 8a measures electronically, for example by means of a pressure sensor or a light barrier, that it bears against the bale of the pressure cylinder 9.
- the transverse offset 7 moves in addition to the clamping jaws 8a, 8b at the same speed with which the clamping jaws 8a, 8b each move.
- the left clamping jaw 8a remains in contact with the bale of the printing cylinder 9, while the right clamping jaw 8b quickly approaches the other side of the bale.
- the pressure cylinder 9 is firmly clamped between the two jaws 8a, 8b.
- the bale length and the total length of the printing cylinder 9 can be measured.
- the crane 3 in FIG. 8 then lifts the pressure cylinder 9 and moves it according to FIG. 9 to the processing station 1, where, according to FIG. 10, it is placed on corresponding holders provided in the processing station 1.
- the printing cylinder 9 is raised again by the crane 3 and brought to the next processing station.
- the crane 3 lifts the printing cylinder 9 out of the processing station and leads it back to the transport carriage 10. There the printing cylinder 9 can be stored until the operator finds time to pull the transport carriage 10 together with the printing cylinder 9 out of the loading station 2 and transport it to the next job. After the pressure cylinder 9 has been placed on the transport carriage 10, the carriage brake, not shown in the figures, is released.
- the crane 3 can also be equipped with a gripper system by means of which the cylinder axes are enclosed and raised. Basically, however, the gripper system works exactly like the clamping system 8.
- the entire device is coordinated by a controller, not shown, which can be operated via a master console.
- the operator can use the master console to enter the loading station number into which he has inserted the printing cylinder 9, the cylinder card using a barcode reader or the cylinder data (at least the length, the bale length and the circumference) by hand.
- the operator specifies the work program, for example using the copper thickness, chrome thickness, the polishing pro- grams, etc. It is also possible to influence the order of processing by specifying a priority.
- clamping jaws 8a, 8b can already be moved apart or moved together while the crane 3 and the transverse offset 7 are still approaching the next charging station 2.
- a device 12 for automatically determining the diameter of the printing cylinder 9 to be lifted can be used.
- the device 12 has at least one light barrier which can be moved with the help of the crane 3 relative to the pressure cylinder 9 to be detected in its radial or axial direction. Since the pressure cylinder 9 can be run over not only in the diameter direction by the light barrier 12, but also in the longitudinal direction, it is possible, in addition to the cylinder diameter, the bale length and - taking into account the distance between the longitudinal center of the cylinder 9 and the stop 11 - the total length of the Print cylinder 9 to measure or calculate.
- the determined data can be compared with the data already stored in the control, which makes a plausibility check possible.
- the control can also select and suggest the appropriate work program.
- the stop 11 cannot be used. In such a case, it is sufficient if the carriage with the hollow cylinder is pushed into the entry space without it having to be positioned exactly. The car only has to stand in a prescribed area.
- the further process corresponds to that described above: the holding elements 8a, 8b are in an outer basic position, the crane 3 lowers and determines the diameter and the central axis. Then the holding elements or clamping jaws 8a, 8b (so-called Chinese hats) move together until either the right or the left holding element touches the right or left end of the cylinder (light barrier).
- the transverse offset 7 moves to the left at the same speed when the left holding element touches the cylinder first, or to the right when the right holding element 8b makes first contact, as a result of which the holding element touching first comes to a standstill in relation to the touched bale end. If both holding elements then have contact, the bale length and position of the cylinder are known.
