Description

The invention relates to a printing press for the production of printed products and a set-up method for setting up a printing press with an ink guide part.

Printing machines, in particular flexographic printing machines, are known from the prior art. Such printing machines often include a format cylinder, which is arranged in particular in the center of other components. For example, inking units are usually provided around the impression cylinder, which contain components that are suitable for distributing the ink and for producing printed products. In particular, so-called ink tanks and / or doctor chambers are part of these components. In the course of the production of the printed products, it is necessary to do so Replace components at least partially, for example, if wear occurs or the print image or ink is to be changed. However, the components to be replaced are usually partly in an overhead area of an operator, which is difficult to access from the floor.

It is therefore known from the prior art to provide a platform which is of elevated design and via which the operator can also reach the components in the overhead region, in particular also with heavy replacement parts. It is also known to provide adjustable lifting platforms so that different areas of the printing press can be reached. However, it is disadvantageous that such lifting platforms block an area around the printing press, so that the platform has to be removed in order to carry out further work steps or the work steps have to be carried out elsewhere. However, this can lead to increased transport routes and / or require an increased production space.

It is therefore an object of the present invention to at least partially overcome the disadvantages known from the prior art. In particular, it is an object of the present invention to make it easier for an operator to set up a printing press and to reduce the production space required for the production of printed products and / or to keep an access area to the printing press at least temporarily free.

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 15.

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 also apply, of course, also in connection with the set-up method according to the invention and vice versa, so that the disclosure of individual aspects of the invention is or can always be referred to mutually.

According to a first aspect of the invention, a printing press for the production of printed products is claimed. The printing press has at least one receiving bearing for receiving an ink guide part, in particular an ink tray and / or a doctor chamber. Furthermore, the printing press has a set-up station for setting up the ink guide part on the receiving bearing. The set-up station also has a work platform and a main guide means for guiding the work platform at least between a work position and a rest position. The work platform is in the work position in a work area and can be entered by an operator in the work position. In the rest position, the work platform is outside the work area.

Printed products can preferably be understood to mean print media, packaging or other printed products. The printing press can preferably be a flexographic printing press which has several inking units. Each of the inking units can have at least one interchangeable ink tray and / or an interchangeable doctor blade chamber.

The ink guide part can preferably be designed to provide ink in the printing press, to take up ink and / or to transport ink. Thus, the work area is particularly accessible to the operator when the work platform is in the rest position and is inaccessible or difficult to access when the work platform is in the work position. The work area can be understood as an area on the printing press or around the printing press in which an operator can move. In particular, the work area can comprise an access area to the printing machine, in particular on the bottom, or can be formed by the access area. For example, the work platform can preferably be arranged in the vicinity of a door to the printing press, so that the operator can get into the printing press via the work platform. If the work platform is no longer required, it can be brought into the rest position so that the work area is free. In particular, the work platform in the rest position can have a height of 2.1 m to a floor area below the work platform. This means that while the work platform is not needed, the work area can be used to carry out further activities. In particular, the rest position can be designed such that it is also possible to drive a lifting truck in the work area. The work platform can preferably form a work surface, on which the operator can stay. For this purpose, the work platform can have a steel structure, for example, which forms a step surface. The main guide means is also provided for transferring the work platform between the work position and the rest position. The main guide means is preferably located outside the work area or only takes up a small amount of space in the work area, so that this does not or only slightly disturbs the further work. In particular, the main guide means can be integrated in a housing of the printing press, for example in which flat linear guides are attached to the outer wall of the printing press, so that these do not or only slightly interfere with work in the work area. In particular, the linear guides can be arranged on both sides of the access area. Equipping the printing press with the ink guide part can preferably be understood to mean mounting the ink guide part in the printing press. The setup station can be provided in particular for the replacement of ink guide parts of the printing press. In particular, the setup station can therefore also be referred to as a changing station and / or assembly station.

Thus, on the one hand, the printing press according to the invention simplifies the replacement of an ink guide part in a simple manner, in that the work platform enables an operator secure access to a corresponding receiving bearing in the printing press, even in an overhead area. This is particularly advantageous because such color guide parts often have a high weight and are therefore difficult to handle by the operator anyway. If the work platform is in the work position, the operator can thus use the access to the printing press at a comfortable height. At the same time, the work platform does not or only temporarily blocks the work area, which can thus be used if the work platform is not required for access to the printing press, in particular in an elevated area. In this case, it may not be necessary, for example, to get to the work platform, so that the work platform can be inaccessible in the rest position, for example in an upper region of the printing press.

In a printing press according to the invention it can preferably be provided that the work platform is in the rest 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 the work area below the work platform is free, so that freedom of movement and / or access to the printing press is facilitated for an operator.

It is also conceivable in a printing press according to the invention that the working position of the working platform corresponds to a running board within the printing press. As a result, the operator can access the running board via the working platform, in particular without having to compensate for a height difference from the working platform to the running board while carrying the paint guide part. Areas in an interior of the printing press can thus be comfortably reached by the operator. In particular, the running board can be located in a production area of the printing press.

In the context of the invention, it is also conceivable that the working position and the resting position differ in a distance from the working platform to a floor area. The work platform is preferably in the rest position above the work area. The rest position can thus preferably be increased relative to the working position and the working area. In particular, the printing press can extend in height beyond the required work area, so that an elevated rest position does not have a disruptive effect if, for example, at the same time there is space in a production hall anyway. Furthermore, the printing machine can also provide a structural fastening height, so that the main guide means can be fastened at least both in the area of the rest position and in the area of the working position, so that the working platform can have sufficient stability in each case. Thus, it can also be ensured, for example, that the work platform does not interfere with any further work even in the rest position and can therefore remain in the rest position, even if further activities are carried out, in particular outside the work area.

It is also conceivable in a printing press according to the invention that the main guide means has at least one rail element, preferably a pair of rails, on which the work platform is mounted. In particular, the work platform can be mounted horizontally on the main guide means. This preferably allows a linear adjustment of the work platform. The rail element represents a simple possibility for designing the main guide means, for example, in such a way that that this extends upwards without being disruptive in the work area. The rail element can preferably be fastened to the one support element of the printing press or integrated into a housing of the printing press. It can thus be provided that the work platform can be arranged to be adjustable on an outside of the printing press. In particular, the rail element can extend parallel to a wall of the printing press and / or to an outer plane of a door of the printing press. At the same time, the rail element can provide a positive connection with a connection area and / or an adjustment area of the work platform, so that a secure connection of the main guide means and work platform is ensured, in particular in the work position and the rest position. The pair of rails, which preferably has two rail elements, can also contribute to the stability of the working platform, in which the working platform can be mounted on the pair of rails, for example by means of two rollers. Additionally or alternatively, it is conceivable that the main guide means comprises a rod guide through which the work platform is guided, in particular in a horizontal position.

It is also conceivable with a printing press according to the invention that a fall protection is arranged on the work platform, by means of which the operator can be prevented from falling off the work platform, in particular if the work platform is in the work position. The fall protection can preferably comprise a railing which has struts through which the operator can reach through the gaps in order to ensure a high degree of mobility on the work platform while the printing machine is being set up with the ink guide part. Additionally or alternatively, the fall protection can comprise a lattice element, by means of which small parts can be prevented from falling off the work platform. It is conceivable, for example, that small parts fall off a paint guide part while working on the work platform, which could damage or be lost when dropped from a great height from the work platform beneath it.

In the context of the invention, the fall protection can furthermore have a fastening interface above the work platform for fastening the fall protection to a support element of the printing press. In particular, if the rest position is provided above the work position and above the work area, the fall protection can thus extend to the rest position extend and thus offer great protection against the operator falling down. Furthermore, the fall protection of the work platform in the work situation can also provide support for the stability of the work platform. In particular, stability is important in the work situation when the operator is on the work platform. It is conceivable that the fall protection can be attached to the support element in a positive and / or non-positive manner via the attachment interface. A form-fitting attachment can, for example, ensure a simpler and more secure design of a detachable connection, so that when the work platform is moved into the rest position, the fall protection can be released and the adjustment is not blocked thereby.

Advantageously, it can further be provided in a printing machine according to the invention that the fall protection has a first and a second protective section, the first protective section being separated from the second protective section by at least one joint. The fall protection can preferably have at least one further joint, so that the fall protection can be folded at least in regions. As a result, it is not necessary, for example, to release the fall protection from the fastening interface when the work platform is moved into the rest position, but the fall protection can be folded up in a simple manner so that it does not block the adjustment. As a result, the fastening interface can, for example, also permit fastening which is mounted on the support element once when the set-up station is installed and then remains on the support element. Thus, the mounting interface can also be a material connection, e.g. allow a weld on the support element. The joints can preferably comprise hinges on which the fall protection can be folded. In particular, several joints can be provided in order to be able to fold the fall protection in a particularly compact manner in the rest position. In this way, for example, even in the case of small printing machines, it is possible to stow the work platform and fall protection above the work area and / or to attach it to the support element, in particular above the work area. The fall protection can preferably have at least two further joints, so that the first and second protective sections are each articulated to the fastening interface and / or to the work platform.

It is also conceivable in a printing press according to the invention that a locking means is provided through which the work platform in the work position and / or Rest position is fixable. In particular, the main guide means can have the locking means, the locking means preferably being able to ensure a positive locking of the working platform in the working position and / or in the rest position. In particular, it can be provided that the work platform is guided on rollers on the main guide means, which in the work position and / or in the rest position rest positively on the locking means or can be brought into engagement with the locking means. In particular, the locking means can be designed as a locking means, so that a simple locking and a simple release of the locking is possible. This can simplify the handling of the work platform, so that little time is required to move the work platform between the rest position and the work position.

In a printing machine according to the invention, an ascent aid can preferably be arranged on the work platform, via which the work platform can be reached by an operator in the work position. In particular, the ascent aid can comprise a ladder and / or a staircase. In particular, if the work platform is at a high height in the work position, the ascent aid can make it easier for the operator to reach the work platform. Even at low heights, however, the ascent aid can make the workflow easier, especially if the operator carries a heavy-duty paint guide part onto the work platform. The climbing aid can, for example, be arranged fixedly on the working platform, so that the climbing aid can be adjusted together with the working platform between the rest position and the working position. In particular, the rest position of the work platform can be located outside the work area such that the ascent aid is also in the rest position of the work platform outside the work area.

In the case of a printing press according to the invention, the climbing aid can advantageously be arranged detachably on the work platform. Additionally or alternatively, it can be provided that the work platform has a guide means into which the climbing aid can be inserted. The climbing aid can preferably be aligned parallel or substantially parallel to a working plane of the working platform when the climbing aid is pushed into the guide means. A detachable arrangement of the ascent aid on the work platform may make it possible to remove the ascent aid from the work platform and to stow it elsewhere. In particular, an ascent aid can thus be used for different work platforms within a production company.

The guide means of the work platform can also provide that the work platform forms an at least partially closed receiving compartment into which the ascent aid can be inserted. If, for example, the climbing aid is a ladder or a staircase, it can preferably have essentially a straight extension and can therefore be stowed away on the work platform in a simple manner. In particular, further space can be saved in that the ascent aid can be pushed into the guide means before the work platform is moved into the rest position. A parallel alignment of the ascent aid to the working level of the working platform also requires a particularly small amount of space when the working platform is in the rest position. In particular if the rest position is provided above the work area, a longitudinal extension of the ascent aid cannot have a disadvantageous effect on the place of production. In particular, the ascent aid can thus be arranged in a drawer-like manner on the work platform. Additionally or alternatively, the climbing aid can be designed telescopically, so that individual sections of the climbing aid can be pushed into one another and thus further space can be saved if the climbing aid is adjusted to the rest position together with the work platform. In order to insert the climbing aid into the guide means, the climbing aid can preferably have a counter-guide means which, for. B. rollers, a rail and / or a sliding surface.

Within the scope of the invention it can further be provided that the work platform can be adjusted manually and / or automatically, in particular by a drive and / or a lifting mechanism, between the work position and the rest position. In particular, several drives can be provided for driving individual movable areas of the setup station. A manual configuration of the adjustability has the advantage that an additional drive is not necessary and manufacturing costs can thus be saved. In order to improve the manual adjustability, the work platform can in particular have a handle. In particular, this means that a further connection of the work platform to an energy system, for example for obtaining electricity, compressed air or the like, can also be dispensed with. As a result, the set-up station can be uniformly suitable for different types of printing presses, in particular without an interface being provided. An automatic adjustment between the rest position and the working position can increase the ease of use, for example, since one operator has none or only has to exert a small amount of physical strength to adjust the work platform. Furthermore, an automatic adjustment of the work platform can allow the rest position to be provided outside the reach of the operator from the floor above the work area. As a result, the work space obtained can be enlarged in the rest position.

In a printing machine according to the invention, it can advantageously be provided that a lifting unit for lifting the ink guide part is arranged on the work platform, the lifting unit being able to be brought into a feed position and a removal position, the ink guide part being able to be picked up by the lifting unit in the feed position below the work platform, and that Ink guide part can be removed from the lifting unit in the removal position above the work platform. Due to the lifting unit, it may not be necessary for the operator to carry the ink guide part onto the work platform manually or for a second operator to hand over the ink guide part to the first operator on the work platform. The arrangement on the work platform also results in a high accessibility of the lifting unit when the operator is on the work platform, so that the ink guide part of the lifting unit can be easily removed and the handling of the ink guide part can thus be simplified overall. The lifting unit can preferably be adjustable manually or automatically between the feed position and the removal position. For this purpose, the lifting unit can be arranged on the work platform so as to be adjustable via at least one linear guide. The adjustability of the lifting unit can thus be made possible in a simple manner, so that the ink guide part can be transported safely from the feed position to the removal position. In particular, the lifting unit can have a locking device, by means of which the lifting unit can be positively and / or non-positively fixed in the feed position and / or in the removal position.

In a printing press according to the invention, the lifting unit can preferably have at least one storage element on which the ink guide part can be deposited. Loading the lifting unit with one or more ink guide parts can thereby be simplified. The storage element can preferably have a recess in which the paint guide part can be received and / or that a storage surface of the storage element has a plastic and / or elastomer. The recess can ensure a positive locking of the ink guide part on the storage element, so that the ink guide part cannot, for example, roll off the storage element when the lifting unit is brought into the removal position. Damage to the ink guide part can thereby be avoided and the risk of falling down can be reduced. The plastic and / or the elastomer of the storage surface can also also ensure that the ink guide part does not slip on the storage element, in particular by means of a coating, so that the risk of the ink guide part sliding down can be reduced. In addition, the plastic and / or the elastomer can be made softer than a material of a storage section of the ink guide part, so that the ink guide part is not damaged by the storage surface and / or is not subject to wear. Alternatively, the storage surface can have a Teflon coating, which can reduce wear.

Preferably, in a set-up station according to the invention, the lifting unit can have at least two storage elements which form a storage element, so that one end of the ink guide part can be deposited on the storage elements. In particular, several storage pairs can be arranged one above the other. As a result, the lifting unit can, for example, first be equipped with several different ink guide parts in the feed position and then be moved into the removal position so that the multiple ink guide parts are available on the work platform. As a result, it is not necessary, for example, to switch several times between the feed position and the removal position in order to equip the printing press with several ink guide parts. In addition, the operator can remain on the work platform and replace several ink guide parts or equip the machine with the ink guide parts so that the set-up time can be shortened here.

It is also conceivable within the scope of the invention that a lifting mechanism and / or a drive is provided, as a result of which the lifting unit can be brought at least from the feed position into the removal position. The drive can preferably be controllable by at least one control element. Additionally or alternatively, the drive can in each case be designed to bring the lifting unit from the removal position into the feed position. The drive can be designed, for example, as an electric motor or as a pneumatic drive or as a hydraulic drive. Furthermore, the drive can be arranged on the work platform or the lifting unit. In particular, however, it is also conceivable that the drive is on centrally the printing press is arranged and thus only z. B. the compressed air of the drive is provided on the lifting unit. The control element can be arranged, for example, on the lifting unit, the work platform and / or a housing of the printing press. For example, it can be provided that the drive is in communication connection with the control element or can be brought. If the control element is provided, for example, on a housing of the printing press, the positioning can already ensure that the operator is outside a fall area in which parts that might fall down could fall out of the moving lifting unit. Furthermore, the control element can provide a convenient way of controlling the drive. The drive also makes it possible for the operator to have to exert little or no physical force in order to bring the lifting unit from the removal position into the feed position and / or vice versa. In particular, this can make it easier to supply the area on the work platform with color guide parts. The lifting mechanism can comprise, for example, a cable pull and / or a chain drive. A cable pull can offer a way to prevent the work platform from skewing. Thus, the cable pull can preferably have one or more, preferably two, cable pull rollers which guide a cable of the cable pull or are guided through the cable. The work platform can preferably be arranged directly on the rope or on the rollers, so that a change in a rope length released in some areas leads to an adjustment of the work platform.

In a printing press according to the invention it can further be provided that at least one lifting support is provided, by means of which a force for supporting a manual adjustment of the work platform and / or the lifting unit can be applied and / or by which an adjustment of the working platform and / or the lifting unit can be damped is. The lifting support can preferably be designed as a counterweight to the work platform and / or to the lifting unit. For example, the work platform and / or the lifting unit can preferably be suspended from a cable and the counterweight can thus counteract part of the weight. This makes manual adjustment of the work platform easier. Additionally or alternatively, the stroke support can have a gas pressure spring. The gas pressure spring can have a cylinder which is filled with a gas under pressure, a cylinder piston being guided within the cylinder with a piston rod. An adjustment the piston rod into or out of the cylinder thus 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 damped in the other direction. The damping can, for example, prevent the work platform and / or lifting unit from falling suddenly when it is unlocked from the removal position or the rest position.

It can also be provided in the context of the invention that a securing element is provided, by means of which the ink guide part can be prevented from falling out of the lifting unit. In particular, the securing element can prevent the ink guide part from falling out of the lifting unit in the removal position of the lifting unit. For example, the securing element can comprise a cage into which the lifting unit moves when the lifting unit is moved into the removal position. Since possible damage in the removal position in the event of the ink guide part falling out of the lifting unit can be large, the securing element here enables a countermeasure which, at the same time, can continue to provide the greatest possible accessibility to the lifting unit in the feed position.

The set-up station in a printing press according to the invention can preferably be arranged on an access area of the printing press, in particular on an interior of the printing press, in particular wherein the printing press has an at least partially transparent door in the access area. The access area of the printing press can thus be part of the work area and allow an operator access to the printing press. In particular, the door and / or the access area can be arranged parallel to the axis of rotation of an impression cylinder of the printing press, so that access to the ink guide parts is simplified. A door in the access area of the printing press can, for example, be sound-insulating during the production of the printed products and at the same time represent a security that, in the event of a defect, for example, parts cannot easily fall out of the printing press. At the same time, the door can ensure that an operator cannot get into the printing press during the production of the printed products. For example, the door can be lockable during the manufacture of the printed products. An at least partially transparent door also allows a look into the printing press. So can For example, the work platform can be entered in the work position to take a look at the printing press during production so that preparations can be made early if parts need to be replaced. During these preparations, the printing press can in particular continue to be operated, so that part of the set-up time can overlap with the production time and thus downtimes can be reduced.

In a printing press according to the invention, provision can preferably be made for a door of the access area to have a grip which extends at least partially behind an outer door plane of the door in the direction of an interior of the printing press. In particular, the door can be the at least partially transparent door. For example, the handle means can include an opening in the door and / or recessed grip in which the operator engages in order to open or push open the door. As a result, the work platform can be adjustable along the door without the grip means preventing the work platform from being adjusted along the outer plane of the door. The work platform can thus be arranged directly on the printing press and thus further space can be saved in the production operation. In particular, the work platform can be arranged directly on the outer door plane and / or can be adjustable parallel to the outer door plane.

• Begehen einer Arbeitsplattform einer Rüststation für das Rüsten des Farbführungsteils,
• Einbringen des Farbführungsteils in die Druckmaschine,
• Verstellen der Arbeitsplattform von einer Arbeitslage, in welcher sich die Arbeitsplattform in einem Arbeitsbereich befindet, in eine Ruhelage, in welcher sich die Arbeitsplattform außerhalb des Arbeitsbereiches befindet.

According to a further aspect of the invention, a set-up method for setting up a printing press with an ink guide part is claimed. The setup process comprises the following steps:

• Walking on a work platform of a set-up station for setting up the ink guide part,
• Inserting the ink guide part into the printing press,
• Adjusting the work platform from a work position in which the work platform is located in a work area to a rest position in which the work platform is located outside the work area.

• Verstellen der Arbeitsplattform einer Rüststation von der Ruhelage in die Arbeitslage.

A set-up method according to the invention thus brings the same advantages as have already been described in detail with reference to a printing press according to the invention have been. In particular, access to the printing press with an ink guide part is facilitated in a simple manner and, at the same time, a work space can be kept free when the work platform is not required. The work platform can be adjusted manually or automatically by a drive. In particular, the work platform can be adjusted along a main guide means for guiding the work platform. The setup method preferably also has the following step:

• Adjusting the work platform of a set-up station from the rest position to the work position.

This can result in a cyclical set-up procedure.

• Ablegen des Farbführungsteils in einer Hubeinheit,
• Verstellen der Hubeinheit zwischen einer Zufuhrposition und einer Entnahmeposition, insbesondere durch Ansteuern eines Antriebs der Hubeinheit über zumindest ein Bedienelement,
• Entnehmen des Farbführungsteils auf der Arbeitsplattform.

The set-up method can preferably further comprise the following steps:

• Depositing the ink guide part in a lifting unit,
• Adjusting the lifting unit between a feed position and a removal position, in particular by controlling a drive of the lifting unit via at least one control element,
• Remove the paint guide part on the work platform.

The adjustment of the lifting unit can preferably be provided from a floor area. Thus, the control element can preferably be arranged on a housing of the printing press, so that the operator has to leave his position of depositing the ink guide part in the lifting unit in order to actuate the control element. This can automatically ensure that the operator is not in a drop area near the lifting unit, so that the operator cannot be injured by falling parts. The lifting unit can also assist the operator in conveying one or more ink guide parts to the work platform at the same time. In particular, a lifting support can support a manual or automatic adjustment of the lifting unit. As a result, the required force of the drive or the manual force can be reduced.

• Anordnen einer Aufstieghilfe an der Arbeitsplattform,
• Einschieben der Aufstieghilfe in ein Führungsmittel der Arbeitsplattform,
• Herausziehen der Aufstieghilfe aus dem Führungsmittel der Arbeitsplattform.

In a set-up method according to the invention, it can further be provided that the set-up method comprises at least one of the following steps, preferably all of the following steps:

• Arranging an ascent aid on the work platform,
• Inserting the ascent aid into a guide means of the work platform,
• Pull the ascent aid out of the guide means of the work platform.

The climbing aid can make it easier to walk on the work platform, especially if the operator is wearing a paint guide or other equipment for assembly. The guide means and the pushing in or pulling out of the climbing aid can ensure that the climbing aid does not protrude into the work area when the work platform is at rest and is stowed away in a safe manner with little storage space requirement.

In a set-up method according to the invention, it can further be provided that moving the work platform from the work position to the rest position includes collapsing fall protection, by which the operator can be prevented from falling off the work platform, and moving the work platform from the rest position to the Working situation includes unfolding the fall protection. As a result, the fall protection can also be safely stowed with the work platform in the rest position, without the fall protection blocking an adjustment of the work platform from the work position to the rest position and without the fall protection requiring further installation space in the rest position of the work platform. In the working position of the work platform, the fall protection means that the operator can move freely on the work platform without his freedom of movement being limited by precautionary measures against falling down due to careful movements. On the one hand, this increases safety during the set-up procedure and, on the other hand, the safe movement of the operator can also shorten the set-up time.

The method steps can take place at least partially in parallel or one after the other in time. In particular, the method steps can be carried out in the order described or in another order. Individual or all method steps can preferably also be repeated.

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

The Figures 1 and 2 show a printing machine 1 according to the invention with a set-up station 10 in a schematic view in a first embodiment. The printing press 1 has a main guide means 12 which guides a work platform 20. The work platform 20 can be walked on by an operator 3 via a climbing aid 30, so that the operator 3 standing on the work platform 20 can look into the printing press 1 through an at least partially transparent door 7 of the printing press 1. Furthermore, the operator can reach 3 receiving bearings 5 of the printing press 1 without having to work overhead. The operator 3 can replace an ink guide part 2 from the printing press 1 or equip the printing press 1 with the ink guide part 2, in particular wherein the ink guide part 2 is mounted on a receiving bearing 5 of the printing press 1. In Figure 1 The working platform 20 is shown in a working position I, in which the climbing aid 30 is extended and the working platform 20 can be walked on by the operator 3. At the same time, the work platform 20 is located in a work area 11, so that access to the printing press 1 is at least partially blocked or the work area 11 is at least partially used by the work platform 20. In particular, the work area 11 can comprise an access area 6 for access to the printing press 1, in particular from a floor area 1.2.

In Figure 2 The work platform 20 is shown in a rest position II, the work platform 20 being outside the work area 11 and the climbing aid 30 being pushed into a guide means 25 of the work platform 20. The work platform 20 can be adjusted along the main guide means 12 between the rest position II and the work position I of the work platform 20. For this purpose, the main guide means 12 has two rail elements 13, which form a pair of rails, so that the work platform 20 is held in a horizontal position. An adjustment 101, 109 between the rest position II and the work position I is therefore particularly linear. To fix the work platform 20 In the rest position II or the working position I, at least one locking means 14 is provided, by means of which the working platform 20 can be fixed in a positive and / or non-positive manner on the printing press 1 and / or on the main guide means 12. The work platform 20 can also be adjusted automatically by means of a drive 43, in particular by actuating an operating element 44, and / or manually, preferably at least one lifting support 27 being provided for the manual adjustment, which is designed as a counterweight and / or as a gas pressure spring can to apply a force that supports the hand force and thus facilitates the adjustment 109 from the work position I to the rest position II. The printing press 1 has a door 7 in the access area 6, which can at least partially block access to the printing press 1. In order to enable access to the printing press 1, a grip means 8 is also provided, which extends at least partially behind an outer plane of the door 7 in the direction of an interior of the printing press 1. As a result, the adjustment 101, 109 of the work platform 20 can also take place completely along the door 7 without the grip means 8 blocking the adjustment of the work platform 20. In order to provide protection against falling of the operator 3 from the work platform 20, a fall protection 21 is also provided, which is designed as a railing. The fall protection 21 offers security against falling and thus increased security of movement on the work platform 20. The ink guide part 2 can preferably be a doctor blade chamber and / or an ink pan.

The Figures 3a and 3b show a schematic representation of a printing press 1 according to the invention with a set-up station 10 in a further exemplary embodiment, the set-up station 10 being able to be configured essentially in accordance with the first exemplary embodiment. The setup station 10 thus has a work platform 20 which is adjustable between a rest position II and a work position I. For this purpose, a main guide means 12 with two rail elements 13 is provided. In addition, however, a lifting unit 40 is arranged on the work platform 20 via a linear guide 45 in order to lift ink guide parts 2 from a feed position Z into a removal position E. The lifting unit 40 is in the feed position Z in Figure 3a shown and in the removal position E in Figure 3b , The lifting unit 40 has a plurality of storage pairs 42, which are each formed by at least two storage elements 41. The storage elements 41 lie opposite one another and are designed to accommodate one end 2.1 of the ink guide part 2.

Thus, the lifting unit 40 can be equipped with a plurality of ink guide parts 2 in the feed position Z and the ink guide parts 2 can be conveyed into the removal position E by the lifting unit 40. In the removal position E, the ink guide parts 2 can be conveniently removed from the lifting unit 40 and exchanged in the printing press 1, or the printing press 1 can be equipped with the ink guide parts 2. In this case, a drive 43 can be provided in order to carry out an adjustment 104 from the feed position Z to the removal position E automatically. The drive 43 can also be used for the adjustment of the work platform 20. Additionally or alternatively, a stroke support 46 can also be provided, which is preferably arranged in the linear guide 45. The lifting support 46 counteracts a weight force of the lifting unit 40, in particular with the ink guide parts 2, so that a manual force for adjusting 104 the lifting unit 40 from the feed position Z to the removal position E can be reduced. Occupational safety can thus be increased in that the operator 3 has to carry lower loads, in particular over lower heights. If the work platform 20 is moved from the work position I to a rest position II, the lifting unit 40 can preferably be adjusted together with the work platform 20. As a result, the lifting unit 40 can also be located outside a working area 11 when the working platform 20 is in the rest position II.

Figure 4 also shows the printing press 1 according to the second embodiment of FIG Figures 3a and 3b in a side view, a securing element 47 being additionally arranged on the work platform 20. The securing element 47 is designed as a cage, into which the lifting unit 40 moves in order to reach the removal position E. In the removal position E, the securing element 47 prevents the ink guide parts 2 from falling out in a direction outside the work platform 20. Furthermore, the printing press 1 has a running board 1.1 which corresponds to the position of the work platform 20, in particular which is in one plane with the work platform 20 when the work platform 20 is in the work position I. Thus, on the work platform 20, an ink guide part 2 of the lifting unit 40 above a floor area 1.2 can be removed and the printing machine 1 can be entered on the running board 1.1 in order to be able to handle the ink guide part 2 inside the printing machine 1.

Figure 5 shows a storage element 41 of a lifting unit 40 in a sectional schematic view. One end 2.1 of an ink guide part 2 is placed on the storage element 41. In particular, the end 2.1 of the ink guide part 2 is located on a support surface 41.2 of the support element 41, the support surface 41.2 having a coating 41.3 which comprises a plastic and / or an elastomer. As a result, wear on the end 2.1 of the ink guide part 2 is reduced if the coating 41.3 comprises a softer material than the end 2.1 of the ink guide part 2. Furthermore, the coating 41.3 can provide a slip resistance so that the ink guide part 2 does not fall out. In addition, the storage element 41 has a recess 41.1 in which the end 2.1 of the ink guide part 2 is mounted, so that the ink guide part 2 cannot easily fall off the storage element 41. In particular, the recess 41.1 can be designed in a form-fitting manner at the end 2.1 of the ink guide part 2.

The Figures 6a and 6b also show work platforms 20 in further exemplary embodiments. For example, the work platform 20 each has a work level 26 which can be reached via an ascent aid 30. In in Figure 6a In the exemplary embodiment shown, the working platform 20 also has a guide means 25, which brings about a positive connection with a counter-guide means 31 of the climbing aid 30. The counter-guide means 31 is designed as a pair of rollers that rolls on the guide means 25. For this purpose, the guide means 25 comprises a rolling surface which is formed on a shoulder of the work platform 20. A drawer is thus formed by the work platform 20 into which the climbing aid 30 can be inserted. Furthermore, the climbing aid 30 has a storage means 31.1, which can be deposited on the guide means 25 of the work platform 20 in order to fix the climbing aid 30 in the inserted position. The rollers of the counter-guide means 31 can in particular be removed from the guide means 25, so that the climbing aid 30 can be detached from the work platform 20. Figure 6b also shows an embodiment of the work platform 20 with a guide means 25, which is formed rail-like and acts with a likewise rail-like counter-guide means 31 of an ascent aid 30 in order to be able to insert the ascent aid 30 parallel to the working plane 26. In particular, it can be provided that the ascent aid 30 is or is inserted in the rest position II of the work platform 20.

The Figures 7a and 7b show a printing press 1 according to the invention with a set-up station 10 in a further exemplary embodiment, a work platform 20 of the set-up station 10 in Figure 7a is in a working situation I and in Figure 7b is in a rest position II. The work platform 20 also has a fall protection 21, by means of which an operator 3 can be prevented from falling off the work platform 20 when the operator 3 is on the work platform 20. The fall protection 21 has a first protective section 21.1 and a second protective section 21.2, which are articulatedly separated from one another and / or from the work platform 20 and / or a fastening interface 23 by at least one joint 22, preferably a plurality of joints 22, 24.1, 24.2. The fall protection 21 is also fastened to a support element 9 of the printing press 1 by the fastening interface 23. The support element 9 can, for example, be a double-T support, which can be designed to support a structure of the printing press 1. The attachment interface 23 and the work platform 20 are articulated by further joints 24.1, 24.2 from the first and second protective sections 21.1, 21.2. As in Figure 7b shown, the fall protection 21 can thereby be folded up, so that the fall protection 21 can continue to be fastened to the support element 9 in the rest position II of the work platform 20 and takes up little space.

The Figures 8a and 8b each further show a working platform 20 of a printing press 1 according to the invention in further exemplary embodiments in a schematic view. The work platform 20 has a lifting mechanism 15 in the form of a cable. Cable pulleys 15.1 are provided for this purpose, which deflect tensioned cables 15.2 above the work platform 20. Furthermore, the lifting mechanism 15 comprises a lifting support 27, in particular in the form of counterweights 15.3, in order to facilitate an adjustment of the working platform 20, in particular between a working position I and a rest position II. The lifting mechanism 15 according to the exemplary embodiment Figure 8a is designed in a simple form, the cable pulleys 15.1 being mounted on a common axis 15.4 for synchronization. The lifting mechanism 15 according to the exemplary embodiment Figure 8b shows several cable pulleys 15.1, each deflecting the cables 15.2. The cable pulleys 15.1 can be mounted on the work platform 20 and / or fixed to the printing press 1. An axis 15.4 is also provided for synchronization, in particular on which the cables 15.2 are guided opposite one another are. The guidance of the cables 15.2 on the axis 15.4 can be realized, for example, by additional cable pulleys. The axis 15.4 can preferably be mounted in the center of the working platform 20.

Figure 9 also shows a setup method 100 according to the invention for setting up a printing press 1 with an ink guide part 2 in a schematic representation of method steps. The set-up method 100 comprises moving 101 a work platform 20 of a set-up station 10 from a rest position II, in which the work platform 20 is located outside a work area 11, in a work position I, in which the work platform 20 is located in the work area 11. A fall protection 21 is preferably unfolded, by means of which an operator 3 can be prevented from falling off the work platform 20. Depending on the mounting of an ascent aid 30, there is then an arrangement 102.1 of the ascent aid 30 on the work platform 20 and / or a pulling out 102.2 of the ascent aid 30 from a guide means 25 of the work platform 20. If several printing machines are provided in a production plant for the production of printed products, a limited number of ascent aids are provided, which are arranged on a plurality of work platforms 20 or which are each stored in a work platform 20 and pulled out. The ink guide part 2 is preferably then deposited in a lifting unit 40 in order to enable the lifting unit 40 to be adjusted 104 between a feed position Z and a removal position E, so that the ink guide part 2 is raised by the lifting unit 40. Adjustment 104 can include actuation of a drive 43 of lifting unit 40 via at least one control element 44. After the lifting unit 40 has been lifted, the operator 3 walks 105 on the work platform 20, so that the ink guide part 2 can be removed 106 from the work platform 20 and the operator 3 then introduces 107 the ink guide part 2 into the printing press 1 can. Subsequently, the climbing aid 30 is pushed in again 108 and the work platform 20 is adjusted 109 from the work position I to the rest position II, so that the work area 11 is free from the work platform 20 and can therefore be used for further activities and / of the machines as long as the work platform 20 is not required.

The above explanation of the embodiment describes the present invention only in the context of examples. Of course, if technically meaningful, individual features of the embodiment can be freely combined with one another without departing from the scope of the present invention.
