Description

The invention relates to a printing machine for the production of printed products and to a setup method for equipping a printing machine with an ink guide part, in particular an ink pan and / or a doctor blade chamber.

Printing machines which are used to produce printed products are known from the prior art. Such printed products can be, for example, print media, packaging or another flat material to be printed. In a flexographic printing machine, for example, several inking units are usually arranged around an impression cylinder so that the inking units are at different heights. Due to technical production requirements, In particular, the inking units are located in an overhead area and / or at a height of the printing press that is difficult for an operator to reach. In preparation for the production of the printed matter, however, it is often necessary to replace individual ink guide parts of the inking units. Such an exchange may also be necessary, for example, due to wear and tear of an ink guide part or due to a change in the image of the printed product. For example, the ink guide parts can comprise an ink pan and / or a doctor blade chamber, through which ink is processed within the inking unit, so that the printed image of the desired printed product is generated. For inking units at certain heights, however, it can require a high level of physical strength for the operator to transport the respective ink tray and / or the respective doctor blade chamber into the printing machine, since these are often heavy and unwieldy. A further disadvantage of known systems is that the printing press is often stopped for a long time in order to replace the ink guide parts, as a result of which the production time for the production of the printed products is interrupted. It is therefore desirable that at least the ink guide part to be exchanged is already available as comfortably as possible to an operator in the vicinity of the exchange position.

From the WO 2003/099 565 A1 a generic printing press is also known.

It is an object of the present invention to at least partially remedy the above disadvantages known from the prior art. In particular, it is an object of the present invention to shorten the set-up time for a printing machine and to simplify the set-up of the printing machine.

The above object is achieved by a printing press with the features of claim 1 and a set-up method with the features of claim 14.

Further features and details of the invention emerge from the subclaims, the description and the drawings. Features and details that have been described in connection with the printing press according to the invention naturally also apply in connection with the setup method according to the invention and vice versa, so that with regard to the disclosure of the individual aspects of the invention, reference is or can always be made to the individual aspects of the invention.

According to the invention, a printing press has at least one receiving bearing for receiving an ink guide part. The ink guide part can in particular be an ink pan and / or a doctor blade chamber. The printing press also has a work platform and a lifting device for lifting the ink guide part for the receiving store. The lifting device further comprises a lifting unit for receiving the ink guide part and a fastening section which is fastened to a support element of the printing press. The lifting unit is movably mounted relative to the fastening section at least between a feed position and a removal position raised to the feed position, wherein the paint guide part can be picked up by the lift unit in the feed position and the paint guide part can be removed from the lift unit in the removal position above a height of the work platform.

Thus, the ink guide part can be conveyed from the supply position to the removal position by the lifting unit. The ink guide part can preferably be designed to provide ink in the printing machine, to receive ink and / or to transport ink. In particular, the lifting unit is designed to receive the paint guide part in the feed position below the height of the work platform. In the context of the present invention, an area can be understood as being located below the work platform, which has a lower height, in particular to a floor area, than the work platform. The area below the work platform can preferably extend directly under the work platform and / or next to the work platform. In the context of the present invention, an area can be understood as being above the work platform, which has a greater height than the work platform. The area above the working platform can preferably extend directly above the working platform and / or next to the working platform. The lifting unit thus in particular forms a lift by means of which the ink guide part on the printing machine can be raised into a position that is favorable for the operator for replacing or equipping the ink guide part in the printing machine. The lifting unit is also mounted on the printing press by the fastening section, in particular so that the fastening section is mounted in a fixed position relative to the printing press. This can ensure that, on the one hand, a secure mounting of the lifting unit is ensured, since the supporting element of the printing press is fixed Represents reference point. Furthermore, external influences during production within the production area, due to the fastening of the fastening section on the support element, in particular do not lead to an adjustment of the lifting device or with less probability. In particular, the mounting of the lifting unit can thus be adapted to the rest of the printing press and the production conditions. The printing machine can preferably be a flexographic printing machine. In particular, the lifting unit can be adjusted on the fastening section in order to switch between the feed position and the removal position. The height of the work platform can be understood to mean, in particular, a distance between the work platform, preferably a step level of the work platform, from a floor area. The fact that the removal position is higher than the feed position means that the lifting unit is at a greater distance from a floor area of the printing machine in the removal position than in the feed position. As a result, the lifting unit can be operated in a simple manner from the floor in the feed position and the paint guide part can be easily removed in the removal position. As a result, a receiving store of the printing machine to be equipped can be reached via the work platform, in particular even if the receiving store cannot be reached from the ground.

Thus, for example, the lifting unit can still be loaded with the ink guide part while the printing press is in production and can be moved from the feed position to the removal position. The printing machine can then be stopped and the ink guide part can be mounted in the printing machine in a position that is comfortable for the operator. On the one hand, this increases the operator's work safety, since he only handles the ink guide part in a certain area and, on the other hand, part of the set-up time for setting up the printing machine can overlap with the production time for producing the printed products by the printing machine, so that the actual loss of production can be reduced can.

The fastening section can preferably comprise a screw connection with the support element. The support element is designed in particular to at least partially absorb and / or carry a load of the lifting device. For example, the support element can comprise a wall of the printing press. In particular, the support element can also be one, in particular on a front area of the Acting press, mounted work platform. The support element can preferably comprise a structural component of the printing press, such as a carrier. In particular, the support element can be present on the printing press anyway, for example to support a roof structure. The fastening section is then preferably fastened to the printing press without, for example, major conversions being required on the printing press. Thus, the lifting device can in particular also be suitable for simple retrofitting on existing printing machines. In particular, the fastening of the fastening section on the support element offers the advantage that the lifting device is fixed on the printing machine, so that a favorable position of the lifting unit relative to the printing machine can be ensured and the ink guide part can be received in a defined manner.

In the context of the invention it can be provided that the lifting unit has at least one storage element on which the ink guide part can be placed. The lifting unit can preferably have at least two storage elements, which form a storage pair, so that in each case one end of the ink guide part can be placed on the storage elements. As a result, the inclusion of the ink guide part in the lifting unit can be significantly simplified. For example, it can be provided that an operator removes the paint guide part from a lift truck and places it on the storage element, in particular the storage pair. In particular, access to the lifting unit can also be simplified if the operator grips the paint guide part at both ends and can insert the paint guide part into the lift unit perpendicularly or essentially perpendicularly to the main direction of extent of the paint guide part. As a result, the time required to load the lifting unit can be reduced, so that the set-up time of the printing press can be further reduced overall. Because the ends can also be placed on the storage elements, it can be ensured, for example, that an outer surface of the ink guide part, which can have sensitive elements such as a printed image structure, does not come into contact with the lifting unit and is therefore not subject to wear and tear or is not damaged will.

In a printing press according to the invention, it can preferably be provided that the lifting unit has several storage elements, in particular several storage pairs, which are arranged one above the other. As a result, the lifting unit can, for example, with several Color guide parts are loaded at the same time and the several color guide parts are transported to the removal position at the same time. In this way, for example, an operator can step onto a work platform after moving the lifting unit into the removal position and from the work platform mount several ink guide parts in the printing machine at the same time without having to leave the work platform. As a result, the set-up time can be further reduced overall, in particular during which the printing press is at a standstill. Additionally or alternatively it can be provided that an exchange of an ink guide part in the printing machine is facilitated by the several storage elements or several storage pairs, since, for example, an ink guide part to be exchanged can be removed, can be placed on one of the storage elements or storage pairs and another storage element or Storage pair the following ink guide part can be removed and mounted in the printing machine. This can also significantly improve the ease of use when setting up the printing press.

In a printing press according to the invention, it can also be provided that the at least one storage element has a recess in which the ink guide part can be received and / or that a storage surface of the storage element has a plastic or an elastomer. Furthermore, the storage surface can have Teflon, by means of which wear of the ink guide part can be reduced. The indentation can ensure, for example, that the ink guide part does not fall from the storage element during the adjustment of the lifting unit from the feed position into the removal position. In particular, a raised edge of the storage element can thus be formed by the recess, so that a form-fitting securing of the ink guide part on the storage element can be ensured. In this way, damage to the paint guide part can be avoided and the risk of it falling down can be reduced. The plastic and / or the elastomer of the storage surface can also ensure that the paint guide part is secured against slipping on the support element, so that the risk of the paint guide part falling down can be reduced. In addition, the plastic and / or the elastomer can be made softer than a material of the end of the paint guide part, which is deposited on the storage surface of the storage element. This can ensure that the ink guide part is not damaged by the storage surface and / or does not experience any wear.

In a printing press according to the invention, it can preferably be provided that the at least one storage element is designed in such a way that the ink guide part can be placed on the storage element in at most two orientations. The ink guide part can preferably be placed on the storage element in only one orientation. For example, the storage element can have a geometric shape which corresponds to a geometric shape of the color guide part. In particular, for example, a first end of the paint guide part can have a diameter which differs from a diameter of a second end of the paint guide part, the storage element preferably being designed to receive the smaller diameter of the two ends in a form-fitting manner. As a result, it is not possible to place the larger diameter on the support element, so that a misorientation is prevented or is quickly noticed by the operator. This can be particularly advantageous in that when removing the ink guide part, the operator can be sure that it is correctly oriented and can therefore quickly mount it in the printing machine without having to pay attention to the orientation.

In the case of a printing machine according to the invention, it can furthermore be provided that the lifting unit is located in the feed position in a work area and in the removal position outside the work area. The work area can include, for example, an area in front of the printing press in which further activities are to be carried out. In particular, the work area can include an access area to the printing machine, which is used by an operator to enter the printing machine, in particular below the work platform. By moving the lifting unit from the feed position to the removal position, not only can the paint guide part be lifted, but the lifting unit can also be put into a rest position in which the lifting unit does not block the work area. In particular, the work area can thus include an area in front of the printing press up to a height, preferably 2.1 m, which allows an operator to comfortably walk through. As a result, the space for the production of the printed products can be used effectively overall and, in particular, different work can be carried out around the printing machine without further restriction by the lifting unit, so that the set-up time of the printing press a required production space can be reduced even further overall.

In the case of a printing press according to the invention, the lifting unit can preferably be mounted on the support element in a suspended manner via the fastening section. Thus, the fastening section can preferably be located above the lifting unit, so that it is mounted, for example, in a guide means of the fastening section. The suspended mounting offers the advantage that a floor area below the lifting unit can be free of the lifting device, in particular at least when the lifting unit is in the removal position. In addition, a work platform can be arranged between the lifting device and the printing machine in a simple manner, on which an operator can move to remove the ink guide part from the lifting unit and to equip the printing machine with the ink guide part, with both the lifting unit and a receiving store of the Printing machine for the ink guide part can be reached easily and quickly by the operator from the work platform. A structural measure to mount the lifting unit past the work platform on a side wall of the printing press is in particular not necessary due to the hanging mounting.

In the context of the invention, it is also conceivable that the lifting unit is movably mounted on the fastening section by a guide means. The guide means can preferably have a rail element, preferably a pair of rails. In particular, the guide means is thus designed for linear guidance of the lifting unit between the removal position and the supply position. For this purpose, the guide means can be arranged to the side of the lifting unit. As a result, a guiding possibility with a high degree of freedom of access can be guaranteed. For example, the fastening section can extend from the support element of the printing machine in the direction of a floor area in front of the printing machine and can have a rail element which provides at least part of the guide for the lifting unit. In particular, the lifting unit can also have a rail or roller element which is guided in the rail element of the fastening section. The pair of rails has, in particular, two rail elements which can advantageously be structurally separate or structurally connected to one another. The locking means can preferably be a locking means include positive fixation of the lifting unit. Additionally or alternatively, the locking means can be provided in terms of control technology. In particular, the locking means can comprise a stop.

It is also conceivable that a lifting mechanism and / or a drive means is provided in a printing press according to the invention, whereby the lifting unit can be brought at least from the feed position into the removal position. The drive means can preferably be controllable by an operating element. The drive means can preferably be arranged on the fastening section so that it is fixed relative to the lifting unit. As a result, the drive means is exposed to lower vibrations, for example, and it is not necessary to also raise the weight of the drive means. The drive means can preferably comprise a chain drive which can transmit force to the lifting unit for lifting the lifting unit with the ink guide part. In particular, the drive means can furthermore comprise an electric motor and / or a pneumatic motor and / or a hydraulic motor. The lifting mechanism can preferably comprise a cable, via which the lifting unit can be moved. The lifting mechanism can in particular be designed to avoid an inclined position of the lifting unit. For example, a cable pull can preferably have one or more, preferably two, cable pull pulleys, which guide a cable of the cable pull or are guided through the cable. The lifting unit can preferably be arranged directly on the rope or on the rollers, so that a change in a rope length released in certain areas leads to an adjustment of the lifting unit. As an alternative to the cable pull, a chain drive is also conceivable, for example. The drive means can also be in communication with an operating element, with a control unit preferably being able to be interposed. The operating element can be arranged on the lifting device itself, preferably on the fastening section. As a result, the operating element can be operated from a work platform, for example, in order to move the lifting unit from the feed position into the removal position, in particular by means of the drive means. Additionally or alternatively, an operating element can be arranged on the printing press and thus the drive means can be controlled in particular from the work area. In particular, the operating element can be located at a distance from the feed position, so that it is ensured that an operator is not in one Stays area in which the operator may be injured by falling parts when moving the lifting unit from the feed position to the removal position.

Within the scope of the invention, it is also conceivable that the drive means is in communication with a control unit which is designed in such a way that the drive means can only be activated under one safety condition. The safety condition can preferably include a query as to whether an operator is in an operating area. The query can include, for example, whether an operating element is pressed by the user. For example, it can be provided that an adjustment is only possible when the operating element is held and the adjustment of the lifting unit stops as soon as the operator stops operating the operating element. This can further increase work safety, since it can be ensured that at least the operator himself does not stay within an area around the lifting unit in which he could possibly be injured by falling small parts or the like. The control unit can comprise, for example, a microcontroller or a processor by which the query can be processed and by which control signals can be transmitted to the drive.

At least one lifting support is also provided within the scope of the invention, by means of which a force can be applied to support a manual, and preferably automatic, adjustment of the lifting unit from the feed position into the removal position. In this case, an adjustment of the lifting unit from the removal position into the feed position can preferably be damped by the lifting support. So it is conceivable that the stroke support comprises a gas pressure spring which is filled with a pressurized gas and in which a cylinder piston with a piston rod is guided inside the cylinder. An adjustment of the piston rod into or out of the cylinder causes a change in the pressure of the gas inside the cylinder, so that a force can be applied in one direction by the stroke support and a movement can be dampened in the other direction. In particular, the damping can prevent the work platform and / or the lifting unit from falling suddenly if it is unlocked from the removal position. Furthermore, the lifting support can have a counterweight to the lifting unit. Thus, the lifting unit can preferably be suspended from a cable and thus the counterweight can be a part counteract the weight of the lifting unit and / or the paint guide part. This facilitates manual or automatic adjustment of the lifting unit. In the case of an automatic adjustment of the lifting unit, for example, the drive means can be dimensioned smaller, since it needs to apply less force in order to effect the adjustment of the lifting unit. The lifting support can advantageously be arranged, for example, on the fastening section and / or on the lifting unit.

In the case of a printing press according to the invention, the lifting unit can advantageously have a catch guard for catching falling parts. For example, a collecting tray can be provided at the lower end of the lifting unit, in which small parts that could possibly fall from the paint guide part or from the work platform can be collected. In particular, the fall protection can comprise a grid through which the falling parts can be caught. As a result, the work safety of the lifting device can be increased overall.

Within the scope of the invention, it is also conceivable that a securing element is provided, by means of which the paint guide part can be prevented from falling out of the lifting unit. The securing element can preferably be arranged in such a way that the securing element blocks the storage element at least on one side when the lifting unit is in the removal position. Thus, the security element can preferably have a wall or a cage which secures the lifting unit, in particular the storage element of the lifting unit, at least on one side in the removal position. The securing element can preferably be arranged on the fastening section or on the printing press, in particular also on the support element. The securing element can thus create a space which is at least partially protected and into which the lifting unit moves so that parts can be prevented from falling down.

It is also conceivable that in a printing machine according to the invention the lifting unit is designed to accommodate ink guide parts which have a length of 500 mm to 2,500 mm, preferably 650 mm to 2,200 mm. Thus, the lifting unit can have a corresponding width, with, for example, a space between Storage elements of the lifting unit can be recessed accordingly. The ink guide parts can preferably be accommodated parallel to a work platform, so that the paint guide parts can be conveniently removed from the lifting unit's work platform. Due to the design to accommodate such long ink guide parts, a special design of the lifting device can be given for use in the field of printing.

In the case of a printing machine according to the invention, it can preferably be provided that the lifting unit is located in the removal position at a distance greater than 1500 mm, preferably greater than 2000 mm, particularly preferably greater than 2500 mm, from a floor area. This can ensure that a work area below the work platform is free from the lifting unit, so that freedom of movement and / or access to the printing press is facilitated for an operator.

It is also conceivable within the scope of the invention that the lifting unit is designed in the feed position for receiving the ink guide part at a distance between 500 mm and 2000 mm, preferably between 1000 mm and 1400 mm, from a floor area. The floor area can preferably be an area of the floor on which the printing press stands and / or via which the printing press is accessible. In particular, the floor area is the subsurface below the lifting unit. Thus, for example, objects can be deposited in the area and / or an operator can move in the area when the lifting unit is in the feed position. In particular, a storage element of the lifting device can be located in the feed position at a distance from the floor area, so that an insertion height that is easily and quickly accessible for the operator can be provided.

Advantageously, it can be provided in a printing press according to the invention that a drive means for adjusting the lifting unit is in communication with a central control unit, which is switched off in such a way that the drive means can only be activated under a safety condition. The safety condition can preferably include a query as to whether an operator is in an operating area. The drive means can thus be connected directly to the electronics of the printing machine, so that an operator can also use the lifting device, in particular the Lifting unit, can be controlled via the central control unit and / or an operating element. The safety condition can also ensure that an operator does not stay in the area of the lifting device when it is moved from the feed position into the removal position.

It is also conceivable in a printing machine according to the invention that the working platform is arranged at least in some areas between a production area of the printing machine and the lifting device, the lifting device being accessible from a first side of the working platform and the mounting of the printing machine being accessible from a second side of the working platform. The work platform can be designed to be adjustable or fixed. The production area can preferably include an area of the printing machine in which the printed products can be produced. The receiving area can be accessed directly or indirectly from the second side. For example, a footboard can be provided inside the printing machine, via which the receiving bearing can be reached from the work platform. The operator can move on the work platform in order to insert the ink guide part from the lifting device into the printing machine. In this way, the operator can work at a height that is easily accessible to him at all times without having to work in an overhead area. As a result, on the one hand, work safety can be increased and, on the other hand, the speed possible for the operator when setting up the printing press can be increased. The work platform can preferably be fixedly mounted with or on the printing machine or it can be arranged on the printing machine in an adjustable manner. For example, the work platform can be designed as a lifting platform which can be raised. As a result, different heights of the printing machine can be controlled via the work platform. In particular, different removal positions can also be provided for the lifting device, so that a removal position of the lifting device can also exist for every possible position of the work platform.

In the case of a printing press according to the invention, provision can also be made for a fall protection to be arranged on the first side of the work platform, which has a penetration opening through which the ink guide part of the lifting device can be removed. The fall protection can thus prevent an operator from falling from the work platform. In this way, the fall protection offers the operator a safety at the same time, so that the operator can move more freely on the work platform without running the risk of falling off. As a result, the operator can increase the speed when loading the printing machine with the ink guide part, so that the set-up time can be reduced overall. Through the access opening, the fall protection also represents a possibility of providing the fall protection with a relevant height in order to offer the operator a high level of safety even in critical situations. The paint guide part can still be removed from the lifting unit, the operator being able to reach through the opening of the fall protection.

• Beladen einer Hubeinheit einer Hubvorrichtung mit dem Farbführungsteil,
• Verstellen der Hubeinheit von einer Zufuhrposition in eine zur Zufuhrposition erhöhte Entnahmeposition,
• Betreten einer Arbeitsplattform durch einen Bediener zur Entnahme des Farbführungsteils von der Hubeinheit,
• Entnehmen des Farbführungsteils zum Montieren des Farbführungsteils in der Druckmaschine.

According to a further aspect of the invention, a set-up method for equipping a printing press according to the invention with an ink guide part is claimed. The setup procedure also includes the following steps:

• Loading a lifting unit of a lifting device with the paint guide part,
• Adjustment of the lifting unit from a feed position to a removal position raised to the feed position,
• An operator enters a work platform to remove the paint guide part from the lifting unit,
• Removing the ink guide part for mounting the ink guide part in the printing machine.

• Verstellen der Hubeinheit von der Entnahmeposition in die Zufuhrposition.

The operator can thus work from the work platform at a comfortable working height and insert the possibly heavy ink guide part into the printing machine. Preferably, the setup process can include the following step:

• Adjustment of the lifting unit from the removal position to the feed position.

As a result, the lifting unit can be made ready again for the next lifting of an ink guide part after it has been removed. However, this may not be necessary, for example, if a working space below the lifting unit is to remain free after the ink guide part has been attached to the printing machine. Thus, the lifting unit makes it much easier for an operator to operate the printing machine with the To equip color guide part, because he has a support through the lifting unit, with which he can convey the color guide part in an overhead area.

In the context of the invention, it is also conceivable that the operator stepping onto the work platform before or after moving the lifting unit from the feed position into the removal position. It can therefore preferably be provided that after the adjustment of the lifting unit and in particular after stepping on the work platform, the printing machine is stopped so that as many work steps as possible can run parallel to a production operation of the printing machine.

It is also conceivable in a set-up method according to the invention that the lifting unit is secured at least in areas against falling out of the ink guide part when the removal position is reached. This can, for example, be carried out on one side by a securing element, which can be designed as a wall or cage, for example. The safeguarding can thus be carried out passively in particular by an existing structural component. Additionally or alternatively, it is conceivable that the operator manually secures the lifting unit against falling out of the paint guide part by, for example, at least partially closing a cage that spans the lifting unit.

The process steps can partially run in parallel or one after the other. The method steps can be carried out in the order described or in a different order. In particular, individual steps or all steps can be repeated.

In the following figures, the same reference numerals are used for the same technical features from different exemplary embodiments.

Figure 1 shows a lifting device 10 of a printing machine 1 according to the invention for lifting an ink guide part 2 for the printing machine 1. In particular, the lifting device 10 for the printing machine 1 can be retrofitted. The lifting device 10 has a fastening section 50 which can be fastened to a support element 9 of the printing press 1 in order to mount a lifting unit 40 of the lifting device 10. For this purpose, the fastening section 50 can in particular be screwed to the support element 9 of the printing press 1. Instead of a screw connection or in addition to a screw connection, however, further fastening options are also conceivable. The fastening section can be shaped, be connected to the support element 9 in a material and / or non-positive manner in order to fasten the lifting device 10 to the printing press 1. The fastening section 50 is designed for hanging the lifting unit 40 on the support element 9 of the printing press 1. The mounting section 50 is mounted above the lifting unit 40, in particular when the lifting unit 40 is in a feed position Z. In the feed position Z, the lifting unit 40 can pick up the ink guide part 2, wherein the lifting unit 40 can be moved relative to the fastening section and can be brought from the feed position Z into a removal position E in which the ink guide part 2 can be removed from the lifting unit 40, in particular from a work platform 20 is possible. So that the adjustment of the lifting unit 40 from the feed position Z to the removal position E is possible, the fastening section 50 has a guide means 52 which comprises a pair of rails having two rail elements 53. The guide means 52 acts with a counter-guide means 48 which is guided by the rail elements 53 of the guide means 52. For this purpose, the counter-guide means 48 can preferably comprise a rail, rollers or the like. As a result, the lifting unit 40 can be adjusted linearly along the guide means 52, so that a secure hold of the paint guide part 2 in the lifting unit 40 is ensured at all times during the adjustment. In particular, it can be provided that the lifting unit 40 is held stable in a horizontal position. To accommodate the ink guide part 2, the lifting unit 40 also has a plurality of storage pairs 42, each storage pair 42 comprising two storage elements 41. An end 2.1 of the ink guide part 2 can be received by an opposing storage element 41, so that an outer surface of the ink guide part 2, which can have a printed image structure, for example, does not come into contact with the lifting unit 40. Damage to the ink guide part 2 can thereby be avoided. The storage pairs 42 are also arranged one above the other, so that the lifting unit 40 is narrow and at the same time removal of the ink guide parts 2 is simplified if they are arranged one above the other, since each of the ink guide parts 2 is accessible from at least one side of the lifting unit 40 at any time. At the lower end of the lifting unit 40 there is also a catch guard 45, which is preferably designed as a grid. This allows small parts that may fall from above to be caught. As a result, work safety can be increased and the freedom of movement of an operator 3 can be increased.

Figure 2 shows the lifting device 10 of the first embodiment in a schematic view in the assembled state of the printing machine 1 for the production of printed products. Furthermore, the printing press 1 has a receiving bearing 5 for receiving the ink guide part 2. For this purpose, the fastening section 50 is fastened to support elements 9 of the printing press 1. A stationary work platform 20 is also provided between the printing machine 1 and the lifting device 10, which has a climbing aid 30 in the form of a staircase or ramp, through which an operator 3 can reach the work platform 20. Furthermore, the work platform 20 has a fall protection device 21 through which an operator 3 can reach in order to remove an ink guide part 2 from the lifting device 10 and feed it to the printing press 1. In the representation of the Figure 2 If the lifting unit 40 of the lifting device 10 is in the feed state Z, an operator 3 can easily reach the lifting unit 40 from the floor area 1.1, on which the printing press 1 is in particular, and equip it with the ink guide part 2 in a simple manner. As in Figure 2 is shown, the lifting unit 40 in the feed state Z is arranged at least in some areas in a work area 11 of the printing press 1, so that an access area 6 of the printing press 1 is at least partially blocked.

Figure 3 shows the printing machine 1 with the lifting device 10 of the first exemplary embodiment, which is shown in FIG Figure 2 is shown, however, the lifting unit 40 of the lifting device 10 is in a removal position E. For this purpose, an adjustment 102 of the lifting unit 40 from the feed position Z has taken place. The removal position E is higher than the feed position Z, the lifting unit in the feed position Z being at least partially below a height H of the work platform 20 and in the removal position E at least partially above the height H of the work platform. Thus, an operator 3 who is on the work platform 20 can reach into the lifting unit 40 located in the removal position E in order to remove an ink guide part 2. For this purpose, the fall protection 21 of the work platform 20 has a penetration opening 21.1 through which the operator 3 can easily remove the paint guide part 2 from the lifting unit 40.

the Figures 4a and 4b further show a printing machine 1 according to the invention with a lifting device 10 in a further exemplary embodiment, the lifting device 10 being designed essentially in accordance with the lifting device of the first exemplary embodiment. The lifting device 10 is fastened with a fastening section 50 to a support element 9 of the printing press 1, a lifting unit 40 being adjustable along a guide means 52 of the lifting device 10. Figure 4a shows the lifting unit 40 in a feed state Z, in which a lifting unit 40, which is located below a height H of a work platform 20, can receive an ink guide part 2. As a result, the lifting unit 40 is easily accessible to an operator 3. The operator 3 can then step onto the work platform 20 via a stepping aid 30, wherein the work platform 20 can be designed as a ladder, for example. Before or after stepping on the work platform 20, the operator 3 can control a drive means 43 via an operating element 44. The drive means 43 can be arranged, for example, on the fastening section 50 of the lifting device 10 and / or on the printing press 1. Furthermore, the operating element 44 can be arranged on the fastening section 50 of the lifting device 10 and / or on the printing press 1. A central control unit 60 of the printing press 1 and / or a control unit 51, which is arranged on the lifting device 10, can also preferably be provided. The control unit 51 and / or the central control unit 60 can query a safety condition as to whether an operator 3 is outside an operating area 44.1, in particular in the specific vicinity of the feed position Z, in which parts when the lifting unit 40 is moved from the feed position Z in the removal position E could fall down. This can be implemented, for example, in that the lifting unit 40 is automatically adjusted only as long as the operator 3 operates the operating element 44. Furthermore, the lifting device 10 has a lifting support 46, by means of which a manual adjustability of the lifting unit 40 from the feed position Z to the removal position E can be supported or by which the drive means 43 can be supported so that it can be dimensioned smaller than without lifting support 46. In particular, the lifting support 46 can comprise a gas pressure spring and be arranged in the fastening section 50. Furthermore, the lifting support 46 can have a damping effect, in which a movement of the lifting unit 40 from the removal position E into the feed position Z can be damped, so that even when the lifting unit 40 is released from the removal position E, a movement of the lifting unit 40 can be damped and not at a high rate Speed drops. As Figure 4a As can be seen, at least one storage element 41 of the lifting unit 40 in the feed position Z also has a distance A from a floor area 1.1 which is between 500 mm and 2,000 mm, preferably between 1,000 mm and 1,400 mm. As a result, the operator 3 in the feed position Z can easily equip the lifting unit 40 without having to work, for example, on an overhead area. As Figure 4b can be seen, the lifting unit 40 is also designed to receive ink guide parts 2 with a length L of 500 mm to 2,500 mm, preferably from 650 mm to 2,200 mm. For this purpose, for example, the storage elements 41 are correspondingly far away from one another, so that the ink guide part 2 rests with one end 2.1 each on an opposing storage element 41 of a storage pair 42.

the Figures 5a and 5b also show printing presses 1 according to the invention in further exemplary embodiments. The printing presses 1 are essentially in accordance with the exemplary embodiment in FIG Figures 4a and 4b formed, but the lifting device 10 also has a securing element 47 which is fastened to the fastening section 50 and / or to the support element 9 of the respective printing press 1. If the lifting unit 40 of the lifting device 10 moves accordingly from the feed position Z to the removal position E, the storage elements 41 are covered on one side, so that in the elevated removal position E, the ink guide parts 2 experience an additional safeguard and they do not move from the lifting unit 40 into one Area next to the work platform 20 fall. At the same time, however, access from the work platform 20 to the lifting unit 40 is ensured, so that the lifting device 40 is accessible from a first side 20.1 of the work platform 20 and a production area 4 of the printing press 1 is accessible on a second side 20.2 of the work platform 20. In particular, the work platform 20 can be at the level of a footboard 1.2, via which the production area 4 of the printing machine 1 can be accessible and / or a receiving bearing 5 of the printing machine 1 for receiving the ink guide part 2 can be reached. In the embodiment according to Figure 5a the securing element 47 is designed as a cage into which the lifting unit 40 is at least partially displaced in the removal position E. As a result, the lifting unit 40 can also be protected on the sides in the removal position E, the lifting unit 40 at the same time being clearly visible. In the embodiment according to Figure 5b the securing element 47 is also designed as a wall which protects the lifting unit 40 on one side in the removal position E against the paint guide parts 2 falling out. This represents a particularly simple design of the security element 47.

Figure 6 also shows a storage element 41 of a lifting unit 40 of a lifting device 10 of a printing press 1 according to the invention in a further exemplary embodiment. One end 2.1 of an ink guide part 2 rests on a storage surface 41.2 of the storage element 41 in a depression 41.1 of the storage element 41. The depression 41.1 provides a safeguard against falling out of the ink guide part 2, since a protruding edge of the storage element 41 secures the ink guide part 2. Furthermore, the storage element 41 has a plastic and / or an elastomer in a coating 41.3. The coating 41.3 can on the one hand prevent the end 2.1 of the ink guide part 2 from being worn when it rests on the support element 41, when the material of the coating 41.3 is made softer than the material of the end 2.1 of the ink guide part 2 others can also be given a slip resistance by the coating 41.3.

Figure 7 also shows a lifting unit 40 of a lifting device 10 of a printing press 1 according to the invention in a further exemplary embodiment in a schematic view. The printing press 1 has a lifting mechanism 54 in the form of a cable pull. For this purpose, cable pulleys 54.1 are provided, which deflect cables 54.2 tensioned above the lifting unit 40. Furthermore, the lifting mechanism 54 comprises a lifting support 46, in particular in the form of counterweights 54. 3, in order to facilitate adjustment of the lifting unit 40, in particular between a feed position Z and a removal position E. The movement can preferably be limited by a length of the cables 54.2.

Figure 8 also shows a setup method 100 according to the invention in a schematic representation of method steps. In this case, a loading 101 of a lifting unit 40 of a lifting device 10 with an ink guide part 2 is initially provided. In particular, the ink guide part 2 can be placed on at least one storage element 41 of the lifting unit 40. The lifting unit 40 is then adjusted 102 from a feed position Z to a removal position E raised to the feed position Z. The lifting unit 40 can be lifted manually and preferably at least partially automatically. This makes it much easier to remove 104 the ink guide part 2 for mounting the ink guide part in the printing press. Preferably, before removing 104 the paint guide part 2, a work platform 20 is stepped on 103 by an operator 3, so that the latter can assume a position from which the lifting unit 40 is also easily accessible in the removal position E. The lifting unit 40 can then preferably be adjusted 105 from the removal position E to the feed position Z in order to make the lifting unit 40 available for the next set-up process in the printing press 1. In particular, the lifting device 10 can be designed according to one of the preceding exemplary embodiments.

The above explanation of the embodiment describes the present invention exclusively in the context of examples.
