Description

The present invention relates to a conveying unit for conveying a printing sleeve from a feeding position to a working position in a printing machine, a conveying device for conveying a printing sleeve from a feeding position to a working position in a printing machine, a system for producing printed matter, and a setting-up method for setting up a printing machine with a pressure sleeve.

Printing machines, in particular flexographic printing machines, are known from the prior art. Such printing machines are used to produce printed products, such as, for example, print media, printed packaging or the like, wherein, for example, a format cylinder may be provided can, on which the printed flat material extends and arranged around the format cylinder inking units, which apply the ink to the sheet. Such inking units usually have different printing sleeves, which are rotatably mounted on receiving bearings of the printing press and distribute the ink or produce the printed image. In the case of a picture change or wear of the printing sleeves, such pressure sleeves must be replaced in the course of operation after a certain time. For this purpose, it is known to drive a plurality of printing sleeves with a trolley to the printing press, remove them from the trolley and insert it into the printing press. When removing the pressure sleeve from the trolley and the insertion of the pressure sleeve in the printing press, however, two persons are normally required because the pressure sleeves are unwieldy and can also have a high weight. In addition, the surface of the printing sleeves in certain areas is extremely sensitive, so that touching this surface by an operator can already lead to a defect of the printing sleeve or the printed image to be produced. A direct sliding of the printing sleeves of the trolley on the printing press is often therefore not possible because the dolly receives a plurality of pressure sleeves and an exact alignment of the respective pressure sleeve against a recording in the printing press by means of the trolley is thus not possible.

It is an object of the present invention to at least partially overcome the foregoing disadvantages known from the prior art. In particular, an object of the present invention is to simplify setup of a printing press with a printing sleeve and to shorten the required set-up time for setting up the printing press.

The above object is achieved by a transport unit having the features of claim 1, a conveyor device having the features of claim 13, a system having the features of claim 17, and a setup method having the features of claim 18.

Further features and details of the invention will become apparent from the dependent claims, the description and the drawings. In this case, features and details that have been described in connection with the transport unit according to the invention, of course, also in connection with the invention Conveying device, the system according to the invention and / or the setup method according to the invention and in each case vice versa, so that with respect to the disclosure of the individual aspects of the invention is always reciprocally referred to or can be.

According to the invention, the transport unit for transporting a printing sleeve from a feed position to a working position, which is located in a printing press, a receiving means for receiving the printing sleeve and a closure unit. The closure unit is thereby brought into a security state, a delivery state and a delivery state. Furthermore, the pressure sleeve can be received by the receiving means in the supply state of the closure unit, wherein the pressure sleeve can be removed from the receiving means in the dispensing state of the closure unit, and a removal of the pressure sleeve in the security state of the closure unit is prevented.

In particular, the pressure sleeve is thus removed from the receiving means in the delivery state and prevents removal in the security state when the pressure sleeve is located on the receiving means. In particular, in addition to the removal and the inclusion of the pressure sleeve can be prevented by the receiving means in the security state of the closure unit. Thus, the receiving means may be inaccessible at least in certain areas. In particular, the supply state, the security state and / or the delivery state can be successively achievable and / or controllable. The supply position may preferably include a storage of the printing sleeves on a transport vehicle, in particular a pallet truck. The working position may also be provided on a receiving warehouse of the printing press. In particular, the working position can thus be the position of the pressure sleeve in which the pressure sleeve is in operation of the printing press. The closure unit can preferably be arranged directly on the receiving means. In particular, the closure unit can connect the receiving means with a transport structure of the transport unit. The receiving means can thus be mounted directly on the closure unit. In the supply state, the pressure sleeve is receivable by the receiving means. Preferably, the transport unit can be arranged in the feed state at the feed position, so that the pressure sleeve, for example. From a trolley, can be applied to the receiving means. To remove the pressure sleeve in the delivery state, the receiving means may preferably at the Working position can be arranged so that an operator can push the pressure sleeve from the transport unit in the working position. In particular, during the removal of the pressure sleeve, the receiving means can store the pressure sleeve together with a receiving bearing of the printing press. In particular, in the security state, the removal of the pressure sleeve is prevented when the pressure sleeve is received by the receiving means. This makes it possible, for example, to move the transport unit from an orientation to the feed position to an orientation to the working position, without the pressure sleeve can fall down and thus can be damaged. In the security state, the closure unit may further obscure an opening or an end of the receiving means to prevent removal of the pressure sleeve. Preferably, a receptacle of the pressure sleeve is prevented in the feed state, so that the receiving means is at least partially closed in the security state by the closure unit. Under the pressure sleeve may preferably be understood a Drucksleeve or sleeve. In particular, the printing sleeve can comprise a printed image structure, by means of which a flat material with a printed image can be printed by means of printing ink. The printing machine may preferably be a flexographic printing machine. For conveying the printing sleeve from the feed position to the working position, the transport unit is designed in particular to be movable. Thus, the transport unit may be guided on a frame or, for example, be moved over rollers on a ground. In particular, the transport of the printing sleeve by the conveying unit from the feeding position to the working position may thus comprise at least part of the distance or the complete distance between the feeding position and the working position. The transport may thus preferably be understood to mean at least a section-wise transport.

In particular, the carriage of the printing sleeve from the supply position to the working position can thus be carried out at least in sections by means of the transport unit. Therefore, it is possible by the transport unit according to the invention to convey the printing sleeve of a trolley in the printing machine in a simple and time-saving manner. The transport unit may require only a single operator to push the printing sleeve from the trolley onto the transport unit and from the transport unit to the printing press. A second operator, who carries a part of the weight of the pressure sleeve, is not necessary in particular by the transport unit. When transferring the locking unit from For example, it may be provided that the receiving means is rotated so that the pressure sleeve is introduced into the conveying unit at a first end and is removed from the conveying unit at a second end opposite the first end. Frequently, however, results from the production process that the printing sleeves are already aligned on the trolley so that a first end, which is oriented from the trolley to the printing press, is to be mounted first in the printing press. Preferably, the pressure sleeve is receivable by the receiving means in the supply state on one side of the receiving means and in the delivery state on the opposite side of the receiving means the receiving means removed. The transport unit thus requires less physical force by the operator to move the printing sleeve from the feeding position to the working position. This has a positive effect on the occupational safety and at the same time the set-up time of the printing machine. On the one hand costs can be saved by the fact that the setup by a single operator is feasible and on the other hand can be done by the transport unit fast, precise alignment of the receiving means at the feed position and then to the working position, so even an adjustment of a lifting platform on which the carriage of the pressure sleeve can take place, may not be necessary.

In the context of the invention it is further conceivable that the receiving means and the closure unit form a lock for the pressure sleeve, whereby the pressure sleeve in the feed state on a receiving side of the transport unit can be received by the receiving means and in the delivery state on a delivery side of the transport unit the receiving means can be removed. Preferably, in the supply state, removal of the pressure sleeve on the delivery side and in the delivery state can be prevented by the closure unit receiving the pressure sleeve on the receiving side. This results in a simple sequence of work steps, which can be executed at high speed by an operator. Thus, for example, a rotation of the receiving means and / or the transport unit is not necessary when removing and receiving the printing sleeve done on different sides. Preferably, the receiving side is opposite or substantially opposite the delivery side with respect to the receiving means. As a result, the alignment of the receiving means at the feed position and at the working position can be facilitated. By the lock effect can be further ensured that the Receiving means in the correct position can be equipped with the pressure sleeve and at the correct position, the pressure sleeve can be removed from the receiving means. Preferably, the receiving means may be arranged horizontally or substantially horizontally on the closure unit and / or a transport structure of the transport unit.

In the context of the invention, it may further be provided that the closure unit has a first closure element and a second closure element, wherein the first closure element fixes a first end of the receiving means in the delivery state and the second closure element fixes a second end of the receiving means in the delivery state. Preferably, the first end of the receiving means is provided on the receiving side and the second end on the delivery side of the transport unit. Thus, preferably, the receiving means may be supported by the closure unit, in particular wherein the storage in the delivery state is realized by the first closure element and in the supply state by the second closure element. As a result, the receiving means can be designed particularly simple. At the same time, the number of components of the transport unit can be made low overall, so that costs of the transport unit can be saved and at the same time results in a low-wear construction. At the same time thereby the lock effect can be realized, which allows a simple sequence of operations to move the printing sleeve from the feed position to the working position.

Preferably, the first closure element in the dispensing state and the second closure element in the feed state can act as a moment support relative to the receiving means. As a result, in the dispensing state, when the pressure sleeve is still received by the receiving means, the closure element can receive a weight of the pressure sleeve by supporting the receiving means, without the receiving means being supported by further measures. In the feed state, at least one weight of the receiving means can likewise be receivable by the second closure element, so that no further support of the receiving means is necessary even in the feed state. As a result, a high degree of constructive freedom can be created for the receiving means, wherein the receiving means can be accessible from both sides for receiving or dispensing the printing sleeve at the same time, without further supports having a disturbing effect. In particular, the receiving means in the supply state and in the delivery state can be fully accessible on one side in each case.

In a transport unit according to the invention, the first and / or the second closure element can advantageously have two pivoting sections, which are designed to grip the receiving means. In this case, each of the pivoting sections may preferably have a guide region for guiding the receiving means when gripping the receiving means. Thus, the first and / or second closure element may be formed by the two pivot portions as a gripper. For example. the first closure element can be detached from the receiving means in the supply state of the closure unit and at least partially surround the receiving means in the dispensing state and / or the second closure element can grip the receiving means in the dispensing state and be released from the receiving means in the feed state. This may result in a suspended storage of the receiving means, whereby a pushing of the pressure sleeve can also be facilitated for the receiving means. In particular, the receiving means may, for example, be designed as a receiving mandrel which is gripped on one side by closure elements. In particular, if the receiving means is designed to tilt on one side in the dispensing and / or in the feed state, it is advantageous if each of the swivel sections has a guide region for guiding the receiving means. Thereby, even if the receiving means tends to be somewhat, it can still be ensured that the receiving means is guided into a secure position in which the receiving means is stored. In particular, it is therefore not necessary to translationally adjust the closure elements so that the closure elements can in particular be mounted only rotationally. A translational movement of one end of the receiving means can still be realized by the guide area.

Preferably, the receiving means is designed such that the receiving means, in particular before the removal of the pressure sleeve, is inclined on one side when the closure unit is in the delivery state. Thus, for example, the first closure element can act as a moment support and a weight of the pressure sleeve and a weight of the receiving means cause the receiving means to lower on one side, in particular along a bending line. As a result, the pressure sleeve can be easier for the receiving means be removed, since pressure sleeve and receiving means are slightly inclined, and thus the pressure sleeve easier from the receiving means, in particular by slipping, can be removed. In particular, the receiving means may be formed such that the receiving means is tilted on one side before receiving the printing sleeve, when the closure unit is in the supply state. As a result, the supply of the pressure sleeve to the receiving means can be simplified, since, for example, the receiving means, if this is designed as a receiving mandrel, may have a lateral surface, which also opposite the pressure sleeve, so that the pressure sleeve is easier pushed. Preferably, the receiving means is dimensioned such that an elongation during the inclination remains within an elastic range of a material of the receiving means. As a result, the life of the receiving means can be increased.

Preferably, the receiving means is a receiving mandrel, on which a passage opening of the pressure sleeve can be pushed in such a way that the pressure sleeve rests with a lateral surface of the passage opening on the receiving mandrel. As a result, it is not necessary for an outer side of the pressure sleeve to be contacted by the transport unit, so that the outer side, in particular completely, can have a pressure structure and the pressure structure is not damaged by contact with the transport unit during transport. At the same time, the receiving mandrel can support a part of the weight of the pressure sleeve when picking up the pressure sleeve and thus support the operator when pushing on and removing the pressure sleeve, so that, for example, the operator merely performs the translatory sliding movement.

It may also be advantageous if, in a transport unit according to the invention, the receiving means has a Einfädelungsbereich and / or a sliding coating, in particular wherein the Einfädelungsbereich and / or the sliding coating, a sliding of the pressure sleeve is facilitated on the receiving means. The threading region may, for example, comprise a chamfer and / or rounding, so that the diameter at one end, in particular at both ends, of the receiving means is reduced and thus a slight deviation in the positioning of the receiving means at the working position or the feed position is tolerable. Furthermore, the sliding coating can further facilitate the pushing on, so that the pressure sleeve experiences only a slight frictional resistance when pushed onto the receiving means. This allows the Carriage of the pressure sleeve from the feed position to the working position to be facilitated.

It is also conceivable that in a transport unit according to the invention, a control unit is provided, by which the closure unit can be controlled such that the supply state and the delivery state can only be reached starting from a security state. In this way, it can be ensured that the receiving means is securely stored at any time during the transporting operation and, in particular, can not fall out of the transporting unit as a result of incorrect operation together with the pressure sleeve or individually if the receiving means is supported by the closing unit. The control unit may further comprise a microcontroller and / or a processor. Preferably, the control unit may be arranged on a transporting structure of the transporting unit or on a frame of a conveying device.

Preferably, in a transport unit according to the invention, a gripping means may be provided on which the transport unit can be moved manually. Preferably, the handle means may comprise a first handle portion and a second handle portion for ambidextrous gripping the handle means. The first and / or second grip portion may preferably each be eccentric. This can result in intuitive ambidextrous gripping of the gripping means, so that the user can operate the gripping means reliably and at the same time it is ensured that the operator comprises the gripping means when the closure unit is transferred from the supply state and / or the delivery state to the safety state. This can ensure that the user is not injured when, for example, two pivoting sections of the first and / or second closure element engage the receiving means, so that a risk of crushing is reduced. Preferably, the first and second handle portions may be arranged such that the first and second handle portions are tangible in a plane. This results in an ergonomically favorable attitude of the user when he moves the transport unit. The manual mobility of the transport unit also results in a simple control possibility of the transport unit, so that the operator can intuitively and quickly adjust the transport unit from the supply position to the working position without, for example, relying on a drive control his. In particular, the transport unit may include a lifting support to support a manual, preferably vertical, movement. Thus, a gas spring may be provided, through which a force for supporting the manual movement of the operator can be applied. Additionally or alternatively, the stroke support can be realized by the drive means.

Advantageously, in a transport unit according to the invention, a drive means may further be provided by means of which the transport unit, preferably vertically and / or horizontally, is adjustable. Preferably, the drive means may be controllable by at least one operating element, which is arranged on a transport structure of the transport unit. For example, the transport structure may include a strut connecting the receiving side and the delivery side of the transport unit. The drive means may preferably comprise an electric, hydraulic and / or pneumatic drive. Thus, for example, a pneumatic drive is advantageous, since pneumatic connections are often present in corresponding production environments in order to supply such drive means with a corresponding air pressure. The operating element can be used with the drive means to enable a fine adjustment of the receiving means, in particular in the vertical direction. Furthermore, the operating element may preferably be configured as a pushbutton, which allows a slight adjustment of the receiving means. Thus, for example, it may be provided that the transport unit is manually adjusted in a rough orientation to the feed position or to the working position and then carried out a fine adjustment via the drive means. Thus, by the drive means, a very fine alignment of the receiving means can be achieved and at the same time the operator can concentrate on the positioning, without e.g. to operate the handle means. Thus, for example, it is conceivable that the operating element is arranged on a remote control, which is connected via a cable to the transport unit or which is designed to be wireless.

Preferably, in a transport unit according to the invention, a, in particular optical, positioning aid can be provided, by means of which a relative position of the transport unit to the pressure sleeve in the supply position and / or to the working position can be determined. The optical positioning aid can, for example, comprise a laser, which is arranged on the closure unit and is oriented such that at a certain distance from the positioning aid can cause a generated laser light to an orientation of the receiving means. Additionally or alternatively, a mechanical positioning aid is conceivable, which, for example, can be folded out in order to determine a relative position of the transport unit to the feed position or to the working position. Additionally or alternatively, the receiving means may be telescopically formed so as to facilitate positioning and / or to facilitate for an operator the transfer of the printing sleeve from the transporting unit to the working position or from the feeding position to the transporting unit.

According to a further aspect of the invention, a conveying device for conveying a printing sleeve from a feed position to a working position in a printing press is claimed. In this case, a transport unit according to the invention is provided, which is movably mounted on a frame. Thus, a conveying device according to the invention brings the same advantages as have already been described in detail with reference to a transport unit according to the invention. By the storage of the transport unit to the frame can be ensured on the one hand, that the transport unit has the necessary mobility to move the printing sleeve from the feed position to the working position and at the same time can absorb the weight required to transport the printing sleeve. Thus, the frame may be preferably fixed, so that a relative position of the transport unit to the printing press and / or the working position is ensured. As a result, for example, be realized that the pressure sleeves acc. a production process are transported from a trolley to the printing press over much of the way and only the removal of the printing sleeves from the trolley is realized in the printing press by the transport unit, in particular by the transport unit distribution of the pressure sleeves can be facilitated in the respective working positions.

In the context of the invention is also conceivable that the transport unit is suspended from the frame. As a result, for example, a footwell below the transport unit can be free and thus continue to be available as a work surface, movement surface and / or as a storage surface. Furthermore, results from the hanging storage the advantage that a simple height adjustment of the receiving means can be realized. Furthermore, the To be attached to frame, in particular, an adjustable lifting platform. This allows, for example, a height adjustment of the receiving means to be carried out to a small extent, so that the operator can work at any time in a comfortable height, without having to extend, for example, in an overhead area. As a result, the safety at work can be further increased and at the same time the time required for the set-up process can be reduced. The lifting platform may preferably comprise a platform with which the frame is adjustable in particular together with a transport carriage for transporting the pressure sleeve.

It is also conceivable within the scope of the invention that the frame has at least one rail on which the transport unit is movably mounted. Preferably, the frame may comprise a pair of rails on which the transport unit is mounted. This results in a simple way to adjust the transport unit along the frame. In particular, the transport unit may comprise rollers which run on the rail or the pair of rails. A sliding guide is also conceivable here. Preferably, a linear adjustability of the transport unit, in particular parallel to a front side of the printing press can be realized by the rail or the pair of rails. Thus, it can be ensured that the distance of the transport unit to the feed position and the working position is maintained and the operator only has to take over the horizontal and / or vertical positioning, but not yet a positioning in another spatial direction.

It is also conceivable that at least the receiving means, in particular the transport unit, is rotatably mounted about a vertical axis, preferably by at least 180 degrees. As a result, for example, a misalignment of a pressure sleeve on the trolley can be corrected, so that even if the pressure sleeve is oriented opposite to the required orientation in the printing machine in the feed position, the printing machine, in a simple manner in the working position can be conveyed. In this case, for example, the supply state of the closure unit can correspond to the delivery state of the closure unit, wherein the reception means is in each case rotated.

According to a further aspect of the invention, a system for the production of printed products is claimed. The system for the production of printed matter in this case has a printing press in which a printing sleeve can be placed in a working position. Furthermore, the system for the production of printed matter has a conveying device according to one of the preceding claims for conveying the printing sleeve from a feed position to the working position. Thus, a system according to the invention entails the same advantages as have already been described in detail with reference to a conveyor device according to the invention and / or a conveyor unit according to the invention. Preferably, the frame of the conveying device can be designed to be fixed at least in one direction to the printing press.

• Aufbringen, vorzugsweise Aufschieben, der Druckhülse von einer Zufuhrposition auf ein Aufnahmemittel der Beförderungseinheit,
• Überführen einer Verschlusseinheit der Beförderungseinheit von einem Zufuhrzustand, in welchem die Druckhülse durch das Aufnahmemittel aufnehmbar ist, in einen Sicherheitszustand, in welchem eine Entnahme der Druckhülse verhindert ist,
• Überführen der Verschlusseinheit vom Sicherheitszustand in einen Abgabezustand, in welchem die Druckhülse dem Aufnahmemittel entnehmbar ist,
• Entnehmen der Druckhülse vom Aufnahmemittel und Einbringen der Druckhülse in eine Arbeitsposition in der Druckmaschine.

According to a further aspect of the invention, a setup method for equipping a printing press with a printing sleeve using a transport unit is claimed. The setup process comprises the following steps:

• Applying, preferably sliding, the printing sleeve from a feed position to a receiving means of the transport unit,
• Transferring a closure unit of the transport unit from a supply state, in which the pressure sleeve can be received by the receiving means, into a safety state, in which a removal of the pressure sleeve is prevented,
• Transferring the closure unit from the security state into a delivery state, in which the pressure sleeve can be removed from the receiving means,
• Removing the pressure sleeve from the receiving means and introducing the pressure sleeve in a working position in the printing press.

In particular, the removal of the pressure sleeve from the receiving means and the introduction into the working position take place simultaneously, preferably so that one end of the pressure sleeve, which is pushed down by the receiving means, is pushed onto a sleeve receptacle in the printing press. Thus, a setting-up method according to the invention entails the same advantages as have already been described in detail with reference to a conveying unit according to the invention. In particular, the transport unit may be part of a conveying device according to the invention and / or part of a system according to the invention. Thus, an inventive setup method also brings the same advantages as have already been described in detail with reference to a conveyor device according to the invention and / or a system according to the invention. The receiving means may preferably be listed as a receiving mandrel, so that the printing press can be preferably pushed onto the receiving means. In particular, the sliding can be carried out such that a lateral surface of a passage opening of the pressure sleeve rests on the receiving means. The transfer of the closure unit from the supply state to the safety state may preferably comprise gripping the receiving device by a closure element of the closure unit. The transfer of the closure unit from the security state to the delivery state may preferably comprise releasing a closure element from the receiving means. In particular, the removal of the printing sleeve from a discharge side of the transport unit can take place and the application of the printing sleeve from a receiving side.

• Überführen der Verschlusseinheit von dem Sicherheitszustand in den Zufuhrzustand.

In the context of the invention, it can further be provided that the setting-up method comprises the following step:

• Transferring the closure unit from the security state to the delivery state.

This is not necessary, for example, if the closure unit is already in the supply state when the pressure sleeve is to be applied to the receiving means. By the interposition of the security state can further be ensured that the receiving means by the closure unit itself is storable and on the other hand, that a secure transport of the pressure sleeve by means of the transport unit is feasible.

• Bewegen der Beförderungseinheit zwischen einer Zufuhrposition und einer Arbeitsposition.

It is also conceivable in a setting-up method according to the invention that the setting-up method comprises the following step:

• Moving the transport unit between a feed position and a work position.

Preferably, the moving can be done at least partially manually and / or at least partially automated. The at least partially automated moving can In this case, for example, be controlled by a control. The at least partially manual movement of the transport unit may, for example, be assisted by a drive means, so that the operator notices only a small proportion of the weight during the movement. For example, the movement of the conveyance unit from the feeding position to the working position does not require that the feeding position and the working position are aligned in advance, but the movement can be performed by the conveying unit in the vertical and / or horizontal direction.

• Ausrichten des Aufnahmemittels an der Zufuhrposition der Druckhülse,
• Ausrichten des Aufnahmemittels an der Arbeitsposition der Druckhülse.

In the context of the invention, it is also conceivable that the movement of the transport unit comprises at least one of the following steps:

• Aligning the receiving means at the feeding position of the printing sleeve,
• Aligning the receiving means at the working position of the pressure sleeve.

The alignment of the receiving means may in particular comprise a fine adjustment by means of a drive means. Furthermore, the transport unit may comprise a positioning aid, which facilitates the alignment of the receiving means at the feed position or the working position. In particular, the alignment of the feed position may, for example, comprise aligning the receiving means parallel to a receiving storage of a trolley and / or aligning the receiving means at the working position may comprise orienting the receiving means at a receiving location of the printing press. As a result, for example, a manual movement of the transport unit can provide a rough positioning and then an alignment of the receiving means by means of fine adjustment. Thereby, the recording of the pressure sleeve or the removal of the pressure sleeve for the operator can be further facilitated, especially when the receiving means is aligned as accurately as possible.

Advantageously, in a setting-up method according to the invention, the closure unit can be moved from the secure state into the supply state by opening a first closure element of the closure unit, in particular wherein the first closure element engages around a first end of the receiving means in the security state and is released from the first end of the receiving means in the feed state. As a result, the storage of the receiving means can be carried out at least partially by the closure unit and at the same time a simple sliding of the pressure sleeve can be facilitated on the receiving means, in particular without the receiving means contacted an outer side of the pressure sleeve.

It is also conceivable in a setting method according to the invention that the transfer of the closure unit from the security state in the delivery state by opening a second closure element of the closure unit, in particular wherein the second closure element in the security state, a first end of the receiving means engages and released in the feed state of the second end of the receiving means is. As a result, at least partial storage of the receiving means can be realized by the closure unit and the removal can be made possible in a simple manner. In particular, the receiving means can thus have a free end in the delivery state, from which the pressure sleeve is merely pushed down or pulled down.

Advantageously, in a setting method according to the invention, the receiving means may tilt on one side, when the closure unit is transferred from the security state to the delivery state, in particular wherein the tendency is at least substantially removed when transferring the closure unit from the delivery state to the security state. The term essentially repealed refers to the fact that further a bending line of the receiving means may be given by the weight of the receiving means and / or by the weight of the pressure sleeve, but at least the two ends of the receiving means may preferably be located in one plane. Depending on the configuration of the receiving means, the inclination can also be completely eliminated in the security state. Due to the inclination, a detachment of the pressure sleeve from the receiving means can be facilitated, in particular in the dispensing state, if it is slightly inclined on one side and thus the pressure sleeve can slide down from the receiving means at least partially. The cancellation of the inclination can be ensured, for example, by a guide region of a closure element.

The method steps may be at least partially parallel or sequentially. In this case, the method steps can be carried out in the order described or in a different order. In particular, individual process steps or all process steps can be repeated.

The FIGS. 2a and 2b In particular, the conveying device 1, preferably the transporting unit 10, has a control unit 34 which is configured such that the supply state II and the delivery state III respectively only depend on the security state I are reachable. Thus, it can be provided that between the supply state II and the delivery state III of the security state I is interposed control technology, so that a faulty operation can be prevented. In this case, a second closure element 22 of the closure unit 20 is closed on the delivery side 10.2 of the transport unit 10 and supports the receiving means 11. Furthermore, two pivot portions 23 of a first closure element 21 are pivoted about a pivot axis and released from the receiving means 11. This ensures a transfer 101 of the closure unit 20 of the transport unit 10 from the security state I in the delivery state II. The first and second closure elements 21, 22 are in particular arranged on a transport structure 15 of the transport unit 10, preferably wherein the receiving means 11 is separated from the transport structure 15 by the closure elements 21, 22. In FIG. 2a the transport unit 10 is aligned with the receiving means 11 at the feed position 3, so that a pressure sleeve 2 from the trolley 8 can be pushed onto the receiving means 11 in accordance with a movement 102. This can preferably be done manually an operator 9 done. During the application 102 of the pressure sleeve 2 on the receiving means 11, the pressure sleeve 2 is at least partially supported by a transport recording 8.1 of the trolley 8 for receiving the printing sleeve 2 on the trolley 8 and at least partially by the receiving means 11 until the pressure sleeve 2 only by the Receiving means 11 is supported.

In FIG. 2b Furthermore, the supply state II of the closure unit 20 is shown, while the pressure sleeve 2 is applied to the receiving means 11. Thereupon, a transfer 103 of the closure unit 20 of the transport unit 10 from the supply state II to the safety state I can take place by the pivoting sections 23 being pivoted towards the receiving means 11, thereby gripping the receiving means 11. The second closure element 22 acts as a moment support, so that a weight of the receiving means 11 and / or the pressure sleeve 2 in particular can be supported on one side.

FIG. 3a shows the closure unit 20 in the security state I, in which a removal of the pressure sleeve 2 is prevented, in which the first and second closure element 21, 22 of the closure unit 20 is closed. In this case, the first and second closure element 21, 22 each encompass a first end 11.1 and a second end 11.2, so that they are fixed. In particular, in the security state I, the transport unit 10 may be rotatably mounted about a vertical axis 14 at least partially rotatable to bring the receiving means 11 together with the pressure sleeve 2 in a favorable position for the removal. As in FIG. 3b In particular, a movement 104 of the transport unit 10 from the supply position 3 to a working position 4 can be performed. In particular, the transport unit 10 is displaced along the rails 33 of the frame 30, preferably linearly, so that the pressure sleeve 2 can be conveyed to the intended working position 4 in the printing machine 6. For this purpose, the operator 9 can grip, for example, the grip means 13 on a first and a second grip section 13.1, 13.2, each with one hand, in particular in one plane, and thereby adjust the transport unit 10 at least partially manually with both hands.

FIG. 4a shows an orientation of the transport unit 10 with the receiving means 11 at the working position 4, wherein the receiving means 11 is aligned with a sleeve receptacle 6.1. In this case, the transport unit 10 can preferably be finely adjusted via the operating element 32 by the drive means 31 being controlled and causing a vertical movement of the receiving means 11. In particular, after completed alignment of the transport unit 10 at the working position 4, as in FIG. 4b illustrated, a transfer 105 of the closure unit 20 from the security state I carried out in the delivery state III, so that the pressure sleeve 2 the receiving means 11 in the direction of the working position 4 can be removed. For this purpose, two pivot portions 23 of the second closure element 22 of the closure unit 20 are pivoted so that the receiving means 11 is released from the second closure element 22 and here the pressure sleeve 2 is accessible. In particular, the pressure sleeve 2 can thus be removed on the delivery side 10.2 of the transport unit 10. In this case, for example, the pressure sleeve 2 can be pushed by the receiving means 11 onto the sleeve receptacle 6.1 of the printing machine 6 in accordance with a removal 106 of the printing sleeve 2. In this case, the pressing sleeve 2 is partially supported by the receiving means 11 and partially through the sleeve receptacle 6.1 of the printing machine 6. Then, the method can be repeated accordingly for the next printing sleeve 2 on the trolley 8.

FIG. 5 shows a transport unit 10 of a system 5 in a partial view with a pressure sleeve 2, which is mounted on a receiving means 11 and wherein the receiving means 11 is supported by a second closure element 22 of a closure unit 20. In this case, the transport unit 10 has a positioning aid 12, which is in particular an optical positioning aid. In this case, a light beam, in particular a laser beam, is emitted by the positioning aid 12, so that a relative relationship of the transport unit 10 or the receiving means 11 to a sleeve receptacle 6.1 of a printing press 6 in a working position 4 can be determined. As a result, an operator 9 has a simple orientation aid in order to be able to estimate geometrically the removal of the pressure sleeve 2 from the receiving means 11 and in particular the supply of the pressure sleeve 2 to the sleeve receptacle 6.1 of the printing machine 6.

FIG. 6 shows a first end 11.1 of a receiving means 11 in a schematic representation, wherein the first end 11.1 of the receiving means 11 by two pivot portions 23 of a first closure element 21 of a closure unit 20 is encompassed. The pivoting sections 23 each have a guide region 23.1 through which the first end 11.1 of the receiving means 11 can be gripped by the first closure element 21 even if the receiving means 11 tilts on one side and thus a receiving region of the closure unit 20 is not concentric with the first end 11.1 the receiving means 11 is. In this case, the guide region 23.1 in each case has a curved or oblique shape, so that the first end 11.1 is guided until it is preferably completely received by the first closure element 21.

The Figure 7a further shows a receiving means 11, which is designed as a receiving mandrel and thus has a rod-like longitudinal extent. A pressure sleeve 2 rests with a lateral surface 2.2, a passage opening 2.1 of the pressure sleeve 2 on the receiving means 11, so that an outer region of the pressure sleeve 2 is not contacted by the receiving means 11. The receiving means 11 further has a Einfädelungsbereich 11.4, which is at least partially formed obliquely, so that the pressure sleeve 2 is easier pushed onto the receiving means 11. Furthermore, in particular an exact positioning of the receiving means 11 may not be necessary. In addition, the receiving means 11 has a slide coating 11.3, by which a frictional resistance between the pressure sleeve 2 and the receiving means 11 is reduced, so that pushing the pressure sleeve 2 on the receiving means 11 and a removal of the pressure sleeve 2 from the receiving means 11 for an operator 9 facilitates is.

FIG. 7b further shows a transport unit 10 with a receiving means 11, wherein a closure unit 20 of the transport unit 10 is shown in a supply state II. The receiving means 11 is supported by a second closure element 22, wherein the second closure element 22 acts as a moment support for the receiving means 11. In this case, the receiving means 11 tilts under its own weight along a direction of inclination 11.5 on one side downwards, since a first closure element 21 of the closure unit 20 is released from the receiving means 11. The receiving means 11 accordingly tilts along a bending line. The inclination along the inclination direction 11.5 is correspondingly greater when a pressure sleeve 2 rests on the receiving means 11 and thus also contributes by its weight at least partially to the bending line. Preferably, the first and / or the second closure element 21, 22 are corresponding to the Embodiment of FIG. 6 formed to compensate for the inclination of the receiving means 11 when the closure unit 20 closes.

FIG. 8 further shows a setup method 100 in a schematic representation of method steps in a further embodiment. Thus, a transfer 101 of a closure unit 20 of a transport unit 10 from a security state I to a delivery state II is initially provided. In the security state I, a receiving means 11 is closed by the closure unit 20 and in the feed state II a recording of a pressure sleeve 2 by the receiving means 11 is possible. Subsequently, an application 102, in particular by pushing, the printing sleeve 2 from a feed position 3 on the receiving means 11 of the transport unit 10 and a transfer 103 of the closure unit 20 from the supply state II to the security state I. This is a movement 104 of the transport unit 10 of the Feed position 3 to a working position 4 of the printing machine 6 at least partially manually and / or at least partially automated possible, wherein the transport unit 10 is adjusted so that the pressure sleeve 2 can be easily pushed onto a sleeve receptacle 6.1 a printing press 6. To further simplify this, it can be provided that the movement 104 comprises an alignment of the receiving means 11 at the feed position 3 and / or an alignment of the receiving means 11 at the working position 4. Subsequently, a checking 105 of the closure unit 20 from the security state I to a delivery state III can take place, in which the pressure sleeve 2 in the receiving means 11 can be removed so that removal 106 of the pressure sleeve 2 can take place from the receiving means 11 and the pressure sleeve 2 are moved to the working position 4 can.
