Definitions

  • the invention relates to a feeder for stacks of flat media, in particular in front of sheet processing machines, such as printing machines, punching machines, mailing machines and, in particular, folding machines, and a method for operating the same.
  • the invention relates in particular to a pallet feeder for folding machines.
  • a sheet In folding machines, a sheet generally passes through individual stations of the folding machine in one direction, which include, for example, a feeder, a transfer table, at least one folding unit and a delivery.
  • a feeder sheets are provided as a stack and separated from the stack by lifting a first sheet in each case by means of suitable lifting and / or conveying means, for example with the aid of suction cups and / or suction wheels.
  • the sheets are then individually fed to the sheet processing machine, in particular a folding machine.
  • a distinction is made among the feeders between pallet feeders and flat pile feeders that work without pallets.
  • Such investors are for example from the DE 86 11 853 U1 and the DE 10 2011 011 322 A1 known.
  • Such investors usually comprise a lifting table or a similar lifting device on which a stack is optionally arranged on a pallet.
  • the stack is fed to further lifting and / or conveying means, such as suction devices and / or suction wheels, which separate the sheets of the stack and feed them separately from one another to the subsequent stations.
  • the lifting table usually carries a stack. When this stack is used up, the lifting table must be moved back to a loading position and loaded with a new stack. During the time required for this, the feeder cannot feed any further sheets to the downstream machine, as a result of which production is interrupted and the productivity of the machine is reduced.
  • a device in which two lifting devices are used to successively feed stacks of paper sheets to a take-off roller. So that the lifting devices do not collide with one another, the support surface for the stacks is formed by rods which extend through a substantially vertical guide surface which is also formed by rods. When a stack is used up, the corresponding lifting device can be withdrawn through the guide surface to create space for the following lifting device.
  • this construction makes it necessary that the stacks of paper sheets are positioned directly on the lifting device, which increases the outlay on equipping and the susceptibility to errors. Equipping with a stack arranged on a pallet or similar carrier medium is not possible, as this would prevent the guide surface from being pulled back. In addition, it is imperative that every stack of paper sheets is completely used up. It is not possible to change the trigger between the stacks.
  • a feeder for stacks of flat media in particular upstream of the sheet processing machine, particularly preferably a pallet feeder for a folding machine, a pull-off device and a first lifting device that can be moved between a loading position and a working position, the first lifting device being arranged in the loading position in this way is that it can be equipped with a first stack and is arranged in the working position in such a way that in each case a medium of the first stack can be withdrawn by the extraction device.
  • the feeder further comprises a second lifting device that can be moved between the or a further loading position and the working position, the second lifting device being arranged in the or the further loading position in such a way that it can be equipped with a second stack and is so arranged in the working position that in each case one medium of the second stack can be withdrawn by the withdrawal device.
  • the first and the second lifting device can each be moved in sections in a rotary and translational manner between the associated loading position and the working position.
  • the second lifting device can be equipped with a second stack while the first lifting device is in the working position and the media of a first stack arranged on the first lifting device is passing through the take-off device can be fed to the subsequent stations.
  • the second stack on the second lifting device can meanwhile be brought into position so that the second stack can be fed to the working position and thus to the extraction device as soon as the first stack has been used up and the first lifting device has been moved out of the working position. This considerably reduces the waiting time in which the take-off device cannot convey any further media.
  • the feeder is particularly preferably a pallet feeder for a folding machine, the first and the second lifting device in this case each being equipped with a stack arranged on a pallet.
  • the flat media lie on top of one another with their wide bases.
  • the flat media are preferably formed from paper, cardboard, foil or other substrates.
  • Preferably the media are in sheet form.
  • the loading position of the second lifting device can correspond to the loading position of the first lifting device, whereby the loading of the feeder with new stacks is simplified.
  • the loading position of the second lifting device can, however, also differ from the loading position of the first lifting device, in particular if this can simplify the kinematics and the structure of the feeder.
  • the working position of the first lifting device corresponds to the working position of the second lifting device and is defined as the position in which the extraction device can each grasp a medium of the stack located in the working position. If the construction of the feeder requires it, the working position of the first lifting device can differ slightly from the working position of the second lifting device. It must be ensured that the withdrawal device can reliably withdraw the media and an offset between the working positions in the alignment device following the feeder can be compensated for. It goes without saying that the first and the second lifting device are always moved in the direction of the pull-off device during operation of the pull-off device in order to track the respective stack and the respective medium to be detected in the direction of the pull-off device. This ensures that the extraction device can always detect a medium of the respective stack.
  • the take-off device captures the topmost medium of a stack.
  • the take-off device detects the bottom medium of a stack.
  • a stack usually has a height of 10 cm to 140 cm, preferably 80 cm to 120 cm, but can be adapted as desired to the media format to be processed.
  • first and the second lifting device can each be moved in sections between the associated loading position and the working position in a rotary and translational manner, the first and the second lifting device can be moved between the associated loading position and the working position without interfering with each other with a relatively simple construction of the feeder collide, with the movement sequences being easy to control at the same time.
  • the first and the second lifting device can preferably be controlled independently of one another.
  • the first and second lifting devices are preferably each mounted in such a way that they can be pivoted between the associated loading position and an intermediate position and can be linearly displaced between the intermediate position and the working position.
  • the first and the second lifting device can also each be mounted in such a way that they can be linearly displaced between the associated loading position of an intermediate position and can be pivoted between the intermediate position and the working position. This ensures a particularly reliable sequence of movements that can be easily implemented in a feeder and enables the feeder to be constructed in a space-saving manner.

This results in a particularly suitable structure for the first and the second lifting device, which requires few and easy-to-design components and enables simple control of the movement sequences.
  • the first shelf is rotatable relative to the first extension arm and the second shelf is rotatable relative to the second extension arm, whereby it is achieved that the alignment of the first and the second extension or the stacks arranged thereon is reversed even when the first or second extension arm is pivoted the first or second axis can be retained.
  • the first and the second boom have suitable connection arrangements for the rotatable connection both with the associated shaft and with the associated tray.
  • first arm and the second arm are each adjustable in their longitudinal direction.
  • the length of the first and the second boom can be varied in order to compensate for an offset of the first and the second shelf that results when the first and second boom is pivoted about the first or second axis.

  • a folding machine is also equipped with a corresponding feeder, whereby its productivity can be increased.
  • Steps a) to e) can be repeated any number of times over a predetermined number of cycles, if necessary.
  • step b) comprises moving the first lifting device from the loading position into an intermediate position and moving the first lifting device from the intermediate position into the working position.
  • step e) further comprises moving the second lifting device from the further loading position or positions into an intermediate position and moving the second lifting device from the intermediate position into the working position.
  • first and second lifting devices (2, 4) can each be moved in sections between the associated loading position (30) and the working position (28) in a rotary and translational manner.
  • the second lifting device can be equipped with a second stack while the first lifting device is in the working position and the withdrawal device separates the media of the first stack and feeds them to the subsequent stations.
  • the second lifting device can be moved directly into the working position, so that the extraction device can extract the media of the second stack immediately after the media of the first stack and feed them to the subsequent stations.
  • the first lifting device can again be equipped with a new stack and are immediately moved into the working position as soon as the second stack on the second lifting device is used up and the second lifting device is moved out of the working position. This reduces the waiting time in which the take-off device cannot separate media and feed it to the subsequent stations.
  • the intermediate position of the first lifting device and the intermediate position of the second lifting device can preferably coincide, but can also fall apart.
  • step b) comprises moving the first lifting device in the direction of the withdrawal device, so that at least one medium of the first stack is always arranged in the intake area of the withdrawal device.
  • step e) preferably comprises moving the second lifting device in the direction of the withdrawal device, so that at least one medium of the second stack is always arranged in the intake area of the withdrawal device.
  • the media of the first and second stacks are tracked in the same direction as a function of the conveying speed of the extraction device, so that the extraction device can always detect a medium of the corresponding stack. It goes without saying that the respective lifting device is also always in the working position during this tracking, even if it continues to move in the direction of the trigger device.
  • the withdrawal device can be designed in such a way that it can detect media from a certain distance range, so that the respective stack only has to be fed back after a predetermined number of withdrawn media.
