Description

15 20 25 30 35 466 598 2 it is not possible for one person to operate several racks.

In addition, the staff works in a noisy and risky area by the stand.

Additional devices for the purpose in question are known, wherein a preparation place for the paper rolls is provided in the transport system which leads the rolls from a warehouse to the rack. However, when a plurality of racks are to be loaded through this conveyor system, such a device can lead to bottlenecks, since both the conveyor system and also the personnel are bound to the work rate of the printing web processing machine.

The present invention has for its object to provide an apparatus of the kind initially described for inserting and removing paper rolls in a roll rotary printing machine, wherein the preparation of the roll to be processed, in particular its sticking point, can be carried out practically independent of the machine plant and outside noise-laden risk zone around the stand.

This object is achieved according to the invention in that the device in question has features according to appended claim 1.

With the aid of such a device, it is possible to automate special sections of the process during the supply and removal of the paper rolls until complete automation of this process for both new rolls and residual rolls.

The device is described in more detail below in connection with the accompanying drawing which shows a possible embodiment.

The simplified presentation schematically shows an arrangement of roller stands, for example under a roller rotation machine with several printing units. 10 15 20 25 30 35 4eß season The device comprises five stations a, b, c, d and e for supplying and removing rollers. Each station a, b, c, d, e is connected by a turntable 1 to the roller transport system 2, which consists of the stations 3, b, c, d, e passing the rails 3 and on these drivable driven carriages 4. The carriage 4 carries the roller 5 from a bearing (arrow 6) and transports it via the turntable 1 to one of the stations a, b, c, d, e.

Each station a, b, c, d, e is provided with a reloading station 7, a roller transfer system 8, a roller stand 9, an elevator bridge 10 and a relief system 11 for residual rollers.

The reloading station 7 consists of two axially parallel rollers 12 and 13 with the supplied roller, which are liftable and one of which is driven, so that the roller lying thereon can be easily rotated.

The roll transfer system 8 consists of rails 14 and drivable carriages 15 running on the rails.

The roller stands 9 have space for two rollers and enable gluing of the paper webs in a known manner. The elevator bridge 10 inserts the roller 16 lying on the trolley 15 under the arms of the frame and lifts the roller 16 to the required height. In the same way, the residual roller 17 is taken from the frame 9 and fed to the relief system 11 for residual rollers.

The unloading system 11 for residual rollers consists of a sliding mechanism 18 which transfers the residual roller 17 from the carriage 21 belonging to the transfer system 8 to the carriage 4 in the transport system 2. An additional storage place 19 is arranged between the transhipment station 7 and the elevator bridge 10.

Before printing, all rolls are prepared. This means for each station a, b, c, d, e that two rollers are located in the stand 9, one roller being provided with a sticking point. On the carriage 15 which is located at the storage place 19, a roll 16 with a prepared sticking point is loaded. On the lifted rollers 12 and 13 in the reloading station 7, which at the same time serves as a storage place, there is a roll which is likewise provided with a sticking point. With this starting position, operation can begin. h, When the first roll is almost consumed in the stand 9, the beginning of the second roll is automatically glued to the flared end of the first roll. The arms of the stand are rotated 180 °. The residual roller 17 is located in the area of the elevator bridge 10, as shown in station a. The carriage 21 goes up on the elevator bridge 10. The elevator bridge 10 travels with the carriage 21 under the axis of the residual roller 20, is lifted and receives the residual roller 20. The elevator bridge 10 is lowered and returns to its original position.

The carriage 21 travels with the residual roller 20 to the unloading system 11, where the sliding mechanism 18 transfers the residual roller 20 from the carriage 21 to the carriage 22, as shown in station b.

The roller 23 prepared with an adhesive point, which waits for the storage space 19 on the carriage 24, now goes up on the lift bridge 10 which then goes under the arms of the stand and is lifted, until the mandrels on the arms of the stand can tension the roller 23. This lifting of the lift bridge can e.g. monitored by a photocell 31. The elevator bridge 10 is then lowered and returns to the initial position. At the same time, the trolley 21 travels with the residual roller 20 via a turntable 1 into the transport system 2 and from there to a warehouse for residual rollers (arrow 25): as shown in station c.

The carriage 26 travels from the elevator bridge 10 into the roller 27, which lies on the lifted rollers 12, 13 and is thereby axially aligned, picks up this roller 27 provided with a sticking point and enters the storage site 19, (II as shown in station d.

The trolley 28 picks up a new roller 29 from storage and travels via the turntable 1 to the transhipment station 7. Where the roller is lifted, 106 20 25 30 35 466 is axially aligned, the empty trolley 28 returns to the rails 3 in the transport system 2 and travels via the rail string 30 to the rail string 31, where it goes into a relief roll 11 system for residual rollers to receive a new failing residual roller. This process is shown in station e.

In the transhipment station 7, the service can now prepare the sticking point on the new roll 29. Due to storage rolls at the transhipment station 7, which at the same time serves as a storage place, and at the storage place 19 the staff is not exactly bound to the printing plant's work rate. known does not require the supply of rollers with regular interruptions.

This process, the special steps of which in the present description are distributed over the different stations a, b, c, d, e in order to clarify the representation, takes place continuously in the same way in each station a, b, c, d, e.

In the case of fully automatic operation of the described system, monitoring elements must be arranged in a known manner, whereby, for example, the process controlled by a programmable control device can be monitored on a panel.

When the transfer system 8 operates independently of the transport system 2, such a plant can be easily integrated into an existing roller transport system.
