Definitions

  • the invention relates to a separating device for separating a stack of sheets of paper or cardboard, with at least one separating device, by means of which the stack for separating the sheets of paper or cardboard can be flown with a gas stream, in particular an air stream.
  • the invention further relates to a separating device for such a separating device and a method for operating a separating device.
  • the US 1 493 167 A discloses a device for separating sheets of a stack.
  • the device comprises stack guides arranged at respective corners of the stack, with flanges arranged at an angle to one another.
  • a jet pipe is received between the flanges, by means of which an air stream can be directed to a corner of the stack to separate the uppermost sheets.
  • the jet pipe has a vertical slot at its upper end.
  • a sheet feeder is known, by means of which individual sheets of paper can be removed from an underside of a paper stack.
  • the sheet feeder comprises a container with components for guiding and holding the paper stack.
  • the paper sheets can by means of a Suction cups are pulled out individually at an outlet at the bottom of the container.
  • a device for separating plates is already the WO 2009/050953 A1 as known.
  • the device there comprises a plurality of ultrasonic vibration units in order to apply ultrasonic vibrations to edges of a plate lying on top of a plate stack that are different from one another and thereby to generate a gap.
  • the device there comprises an air nozzle for blowing gas into the gap between the top plate and the plate stack in order to separate the top plate from the plate stack.
  • the DE 1 561 173 A1 discloses an apparatus for mechanical ventilation of stacks of cardboard or paper sheets.
  • the stack is tilted, ie lying horizontally on a side surface, which is formed by the sheets stacked one on top of the other, so that the foremost sheet and the rearmost sheet of the stack are at one level.
  • the apparatus has a lifting element, by means of which individual cardboard sheets of the stack can be shifted from their original position in the vertical direction and set in vibration. For better separation of the individual, shifted cardboard sheets, compressed air flows over them through a nozzle of the apparatus, the nozzle being arranged opposite the lifting element, so that the stack is located between the nozzle and the lifting element.
  • the invention has for its object to provide an improved separating device, an improved separating device and an improved method of the type mentioned, by means of which the separation of sheets of a stack takes place particularly reliably and with little effort.
  • a first aspect of the invention relates to a separating device of the type mentioned at the outset, by means of which sheets of a stack are separated in a particularly effortless and reliable manner, it being provided that a separating device for aligning the stack has at least one angled aligning unit and at least one as a through-opening through the angled alignment unit formed, first opening, by means of which the stack for separating the sheets of paper or cardboard can be flowed against with at least one gas stream.
  • the angled alignment unit can be applied to at least one side surface of the stack with at least one wall element of the alignment unit.
  • the angled alignment unit can thus prevent the individual sheets of paper or cardboard, which are referred to as sheets in the following for simplicity, from moving in an undesirable manner relative to one another, which can be the case in particular when the stack is flown against by means of the gas stream.
  • an air cushion or an air gap is introduced, by means of which it is prevented that when the stack is separated, i.e. when the top sheet in each case is lifted off the stack, it lies underneath Sheets are lifted off and transported away. Due to the inflow with the gas stream, the separation is thus particularly inexpensive since simple sheets prevent several sheets from sticking to one another.
  • the configuration of the angled alignment unit with the first opening enables both a defined flow and the alignment of the stack.
  • any possible simultaneous transport of several sheets can lead, for example, to faults in further processing machines which are to be supplied with individual sheets by the singling device.
  • printing, embossing and / or cutting devices for sheets of paper or cardboard can be given here, on which faults are caused if they are loaded with a thin stack of two or more sheets.
  • This is particularly effectively prevented by the gas flow generated and directed by the separating device according to the invention.
  • the use of an air stream as a gas stream is particularly useful because of the uncomplicated handling of air.
  • the through opening and thus the gas flow is aligned, for example, on one side surface of the stack and thus perpendicularly on the side edges of the sheets lying one on top of the other.
  • the through opening or the gas flow could also be inclined in the direction of the contact surface of the stack instead of this horizontal orientation and thus enclose an acute angle with the surface of the uppermost sheet. If the gas flow is of sufficient intensity, apart from the paper or cardboard sheets described, sheets made of plastic, wood or metal or any other material can also be separated from one another by means of the separating device.
  • the angled alignment unit has at least one second opening, by means of which the gas flow can be flowed onto the stack for separating the sheets of paper or cardboard, the gas flow being divisible into at least two partial flows by means of the first opening and the second opening, which are on the stack are aligned and wherein the second opening, like the first opening, is designed as a through opening.
  • the first opening and additionally or alternatively the second opening can also be, for example, parallel to the contact surface of the stack and thus parallel to Have slotted nozzle end piece or a slit constriction contact surface between the arches, which are accordingly arranged on the angled alignment unit.
  • the gas flow is thus particularly wide and forms a particularly uniform, wide gas cushion between the adjacent arcs.
  • it can be effectively and specifically prevented that too many of the arches lying on top are flowed to at the same time, but in particular only the uppermost two arches.
  • the flow rate of the gas stream can be increased.
  • the gap between the arcs can then be produced more easily compared to a round cross section of the first opening and additionally or alternatively the second opening even with a reduced gas flow.
  • the angled alignment unit for aligning the stack has at least two wall elements arranged perpendicular to one another.
  • the two wall elements can be arranged at right angles to one another, for example, and can be integrally connected or alternatively screwed to name just a few possible types of connection.
  • the arrangement at a right angle is not absolutely necessary, but should advantageously be adapted to the corner angles of the sheets to be separated. If, for example, the arches have a hexagonal contour, there is the possibility that the two wall elements accordingly enclose a 120 ° angle and can thus be placed close to the stack of hexagonal arches.
  • the two wall elements thus form a suitable stop for aligning the stack in the region around an edge of the stack, which is enclosed at least in regions by the two wall elements of the angled alignment unit.
  • the passage opening for the gas flow can be arranged, for example, on an edge of the sheet of the stack lying on top opposite this edge, so that any offset of the sheets relative to the rest of the stack by the angled alignment unit is effectively prevented when the gas flow is applied ,
  • By enclosing the edge in regions at least in the uppermost region of the stack by the angled one Alignment unit effectively prevents a drift caused by the gas flow, that is, the relative movement between the uppermost sheet or the sheets lying on top and the rest of the stack, in at least two directions lying in a horizontal plane.
  • the “uppermost area” of the stack is to be understood as the area of the stack in which the sheets of paper or cardboard are individually lifted off the stack.
  • the angled alignment unit thus surrounds a corner of the stack, which forms a base region, i.e. facing away from a support area of the stack, at least in some areas.
  • the angled alignment unit or its wall elements which form an angle, such as a right angle, are arranged in the uppermost region of the stack and at least partially enclose one of the corners of the stack there. This specifically aligns the sheets in the stack that are least loaded by the other sheets.
  • the uppermost sheet or the uppermost sheets of the stack have the least weight and can therefore drift away particularly easily when the gas stream is blown in.
  • the lower arches are pressed on by the weight of the arches lying above them and for this reason alone tend less to be exposed to any misalignment or slipping caused by the gas flow.
  • the respective flow directions of the two partial flows which are predetermined by the first opening and the second opening, intersect after they emerge from the openings.
  • the partial flows can both flow in, for example, at a corner of the upper or uppermost arches and thus produce a gap induced by the gas flow between the respectively adjacent arches lying on top at this corner.
  • the respective corner is formed by a first edge and by an adjacent second edge, for example at right angles to the first edge, of the respective arches lying on top.
  • One partial flow is now aligned, for example, perpendicular to the first edge and the other partial flow perpendicular to the second edge.
  • the vertical flow has at least a first flow component, which is directed towards the contact surface of the stack, and a further, second flow component, which is coaxial with it and which is oriented in the opposite direction.
  • the first and second openings for the gas flow can, for example, also be aligned axially in alignment with one another on the separating device.
  • first opening is designed as a through opening of the one wall element and the second opening is designed as a through opening of the other wall element of the alignment unit, both openings being supplied with compressed air, for example, via a common supply connection of the separating device.
  • first opening and the second opening are connected to one another within the separating device, that is to say within the angled alignment unit.
  • the partial flows can both flow towards one another at the corner of the stack, for example, and be aligned axially to one another.
  • the separating device comprises two separating devices which are held on opposite sides of a holding device of the separating device at a distance from one another which at least essentially corresponds to an edge length of the stack. Because the separating devices are kept at a distance from one another which at least essentially corresponds to the edge length of the stack, the gas streams of both separating devices can be oriented in a targeted manner to adjacent corners of the paper or cardboard stack. The separators are therefore kept at a distance in which their alignment units are particularly close to the stack. This creates a uniform air gap on the one hand between the sheets to be separated, which particularly effectively prevents relative adherence of the sheets to be separated. In addition, the area of the paper or cardboard stack on which the alignment units are in contact is reliably protected against moving or shifting of the sheets to be separated. A relative movement of the two separating devices to one another is effectively prevented by means of the holding device.
  • the separating device comprises at least one vibration device by means of which impulses, in particular mechanical impulses, can be exerted on the stack.
  • the vibration device preferably exerts impulses on the side surfaces of the stack, and thus on the edges of the sheets lying one on top of the other.
  • the sheets are moved relative to one another over a short distance, which is limited by the alignment unit, that is to say after which the sheets are in contact with the alignment unit, which favors the formation of the air cushion or gas cushion between the sheets to be separated.
  • the alignment unit that is to say after which the sheets are in contact with the alignment unit, which favors the formation of the air cushion or gas cushion between the sheets to be separated.
  • the impulses there is a transition from static friction to sliding friction between the sheets to be separated.
  • the gas cushion that is to say the gap or air gap between the arches, is formed at least in regions, which is further increased by the inflow with the gas flow or the partial flows of the gas flow.
  • the pulses generate a minimum gap between the arches lying one on top of the other, thereby creating a particularly effective manner for the gas flow to be attacked, in which the gas flow can flow in particularly effectively between two adjacent arcs which are to be separated.
  • the vibration unit can be operated independently of the angled alignment unit and can be arranged separately from it. In particular, the vibration unit is arranged in the area of the paper and cardboard sheets to be separated. There is also the possibility that the vibration device is arranged on the angled alignment unit.
  • the angled alignment unit itself vibrates, which is made possible, for example, by vibrating Plate elements are arranged on the wall elements.
  • the vibration device is integrated in the angled alignment unit.
  • the impulses generated by the vibration device can be matched particularly specifically to the inflow by the gas stream.
  • this comprises guide elements, by means of which at least some of the sheets of paper or cardboard to be separated from the stack can be aligned along a separating direction.
  • the direction of separation corresponds to the direction along which the sheets to be separated are moved away from the stack.
  • the separating device has at least one hold-down device for temporarily holding down the paper or cardboard sheets of the stack.
  • a compressive force directed in the direction of the contact surface of the stack can be exerted on the sheets of the stack shortly after a single sheet has been lifted off the stack.
  • moving along as a result of a suction effect which can be exerted on the underlying sheet by lifting off the uppermost sheet or blowing away further sheets can be effectively prevented.
  • the separating device comprises at least one transport device for lifting sheets of paper or cardboard to be separated and moving the sheets of paper or cardboard to be separated relative to the stack. While a particularly uniform gas cushion is formed between the sheets to be separated by means of the inflow with the gas flow, the transport device is used for Lift the top sheet and move it along the direction of separation. A holding force is exerted on the sheet to be separated by means of the transport device, as a result of which it can be moved away from the stack particularly quickly.
  • the transport device can have at least one vacuum suction device for lifting the sheets of paper or cardboard to be separated. By means of the vacuum suction device, the holding force can be applied to the sheet to be separated in a particularly gentle manner, without the sheet being damaged.
  • a second aspect of the invention relates to a separating device for a separating device, wherein the separating device can be used to flow against a stack for separating sheets of paper or cardboard from the stack with a gas stream, in particular an air stream.

  • the separating device can be made particularly compact and can therefore be attached to the separating device in a particularly small space. For this reason alone, the separation of the sheets by means of the separating device can be carried out with little effort.
  • the separating device also enables particularly fast and reliable separation of the top sheets of the stack.
