Definitions

• the invention relates to reel changers with a reel stand and a method for disposing of residual sleeves according to the preamble of claims 1, 2, 3, 4, 18 and 30, respectively.
• Find reel changers e.g. B. use in rotary printing and serve to feed a web of material, such as a paper web, in a printing press.
• a material roll With rotary printing, the material web to be printed is unwound from a material roll.
• This material roll is rotatably mounted in the roll changer, whereby sufficient paper tension must be ensured when pulling off the material web. If a roll of material is almost exhausted, i. H. the material web spooled on the material roll essentially unwound, this material roll must be replaced by another, new material roll.
• at least two separate receptacles are provided for storing two material rolls.
• the roll change between the old and the new material roll can be realized by a manual roll change with appropriate machine downtime, by flying roll change or a standstill roll change with web storage.
• the old material roll is replaced by the new material roll
• the remaining sleeve of the unwound old material roll is removed from the holder of the roll changer in order to make room for a new material roll for the next roll change. I.e. in other words, that after each reel change, a reeled off sleeve must be removed from the reel changer.
• the removal of the remaining sleeves can be carried out manually by the operating personnel on the reel changer. If the residual sleeves are to be removed automatically, appropriate residual sleeve logistics is required. Is from the prior art it is known to transport residual sleeve containers after the roll change to the roll changer. The supply lines on which the material rolls are also transported to the roll changers are used to transport the residual sleeve containers. As a result, the supply of the reel changer with new material reels and the disposal of the reel changer from the unwound remaining sleeves must be realized on a common transport line. Especially in the case of more complex machine lines with several reel splicers, the production process can be impeded.
• DE 196 11 494 A1 discloses an unwinding system for winding rolls, in which the remaining sleeves are transported in their longitudinal direction out of the roll changer.
• WO 95/20537 A1 shows a reel changer with an additional lifting device for residual reels arranged in the reel changer.
• EP 0454634 A2 shows a rotating transport device for feeding sleeves to a winding machine.
• GB 2 191 967 A discloses a transport trolley for residual rolls with a lifting device for the residual roll holder.
• the invention has for its object to provide reel changer with a reel stand and a method for disposing of residual tubes. This object is achieved by the features of claims 1, 2, 3, 4, 18 and 30, respectively.
• An advantage of the reel changer with conveyor device is, in particular, that a permanently installed conveyor device is provided on the reel changer, with which the at least partially unwound remaining sleeves can be removed from the reel changer after the receptacles have been released. I.e. in other words, a separate transport line is created for the disposal of the unwound remaining sleeves, on which only the remaining sleeves are transported away from the reel changer.
• the transport line for supplying the reel changer is relieved of the remaining sleeve logistics and the logistics of the production processes are simplified overall. Because the sleeve containers no longer have to be transported to the individual roll changers for the removal of the remaining sleeves, it is possible to buffer additional material rolls in the supply system instead of the sleeve containers. Overall, there are shorter cycle times for the roll supply for the individual roll changers, since new material rolls and remaining sleeves are fed in and out in separate ways.
• the conveying device is arranged in such a way that it is carried out transversely to the longitudinal axis of the material roll under the roll changer. This ensures that the residual sleeves reach the conveyor under the influence of their own weight after loosening the receptacles in the reel changer. In this way, separate drive devices for conveying the remaining sleeves from the receptacle to the conveying device can be dispensed with.
• guide devices for example spring bands and / or inclined planes, between the receptacle of the remaining sleeve in the reel changer and the conveying device arranged underneath.
• Guide devices guide the movement sequence of the remaining sleeves from the receptacle in the reel changer to the conveying device, thereby preventing malfunctions, for example stuck remaining sleeves.
• the maximum drop height of a residual sleeve can be reduced, for example, by inclined planes, since the residual sleeve rolls downward on the inclined plane and continuously overcomes the required level difference between the receptacle and the conveying device.
• the reel changer with the receptacle carrying the residual sleeve should be moved before loosening the receptacle in such a way that the level difference between the residual sleeve and the conveying device is as small as possible. Only when the reel changer has reached this lowest ejection position, for example in the vertical position of the reel stand, is the receptacle released and the remaining sleeve falls onto the conveying device underneath.
• the conveying device can be arranged such that it extends between at least two reel changers. In this way it is possible to use a reel changer to remove the remaining sleeves from two or more reel changers.
• the conveyor device is driven continuously regardless of the loading with residual sleeves. It can thereby be achieved that the remaining sleeves can be thrown off the reel changers at any time and removed by the conveying device.
• a special triggering of the conveyor, depending on the disposal requirements of the reel changers, can be omitted.
• the manner in which the conveyor is constructed is basically arbitrary. It is particularly advantageous if the conveyor device is at least partially closed and revolves.
• belt conveyors or chain conveyors can be used to form the conveyor device according to the invention be used.
• several such rotating belt conveyors or chain conveyors can also be arranged one behind the other.
• driver elements can be provided on the conveying device. These driver elements protrude, for example, from the revolving conveyor belt or the revolving chain and can come to rest on the remaining sleeves. By means of correspondingly protruding driver elements, it is also possible to convey the remaining sleeves upwards, starting from a certain starting level, without the remaining sleeves rolling back against the conveying direction.
• Figure 1 shows a reel changer with conveyor in longitudinal section.
• Fig. 2 shows the reel changer with conveyor according to Fig. 1 in cross section.
• a printing press To supply a web processing machine, not shown in FIG. B. a printing press, with rolls of material 02, z. B paper rolls 02, several roll changers 01 are provided, which are arranged one behind the other in a line. Of the roll changers 01, only the roll changer 01 arranged on the extreme left is shown in FIGS. 1 and 2.
• each roll changer 01 two material rolls 02, z. B. rolls of paper 02 are rotatably supported. Serve to store the paper rolls 02 each Receptacles 03a and 03b or 04a and 04b arranged on the end face, each with a mandrel 06 (see FIG. 2).
• the mounts 03 and 04 can be moved apart or moved together laterally.
• the mandrels 06 are inserted into sleeves 07 arranged in the center and fixed there by expansion elements.
• a transport system with drivable transport trolleys 08 is used, on each of which a new paper reel 02 can be transported.
• the roll stand 09 with the receptacles 03 and 04 is pivoted about a pivot axis 10 of the roll stand 09 in accordance with the desired position of the paper rolls 02.

• the roll changer 01 is first pivoted to such an extent that the receptacles 03a and 03b or 04a and 04b with the residual sleeve 12 fastened therein reach their lowest point relative to the base of the foundation 11. In this lowest ejection position, the two receptacles 03a and 03b or 04a and 04b are moved apart laterally, so that the mandrels 06 are pulled out of the residual sleeve 12 and the residual sleeve 12 is thereby released.
• the residual sleeve 12 falls under the influence of gravity onto a conveying device 13 carried out under the roll changers 01 and is removed from the roll changer 01 by the conveying device 13.
• the conveyor 13 is substantially in the middle of the Roller stand 09 arranged.
• the conveyor 13 is transverse to the longitudinal axis of the material roll 02 completely, i. H. from one side to the other side of the reel changer 02, carried out under the reel changer 02.
