Definitions

  • the present invention relates to a device according to the preamble of claim 1
  • a book cover machine with a horizontal processing principle which combines cover boards and a spine insert made of cardboard or cardboard with the reference blanks provided with adhesive in a rolling device.
  • the protruding edges of the book cover are then folded in consecutive work stations either continuously or at a standstill.
  • Left-hand and right-hand corner removal devices are arranged along the panel feed, with which, as the reference panels pass through, corner sections with a predetermined removal width are separated from the reference panel at the leading and trailing edges.
  • the rotary tools of the corner ejectors are driven by a servomotor, which enables electronic adjustment of the ejection width according to the respective height and open width of the book covers.
  • the corner sections should be completely separated from the reference panel in order to obtain a clean cut.
  • tool wear should be kept as low as possible. For this it is necessary to set the center distance between the cutting cylinder and the counter-pressure cylinder very precisely. The material properties of the reference panel and the respective condition of the knife and impression cylinder must also be taken into account.
  • a circular shears for lengthwise cutting of webs is from the DE4125508A1 known. Knives and counter-knives are each on one end of the shaft appropriate. A drive element is provided on the respective opposite shaft end. The bearings of the shafts are arranged between the blade and the drive element. It includes several roller bearings accommodated in a common bush. The bushing is eccentric and rotatably mounted in a frame. The rotational position of this socket in the frame determines the center distance of the knives in the circular shears.
  • the proposed arrangement only allows parallel displacement of the axes of rotation within a tool and does not provide any possibility of avoiding or at least compensating for the elastic deformation of the blade shafts.
  • a device is used to produce book covers, box covers or game boards from at least one cardboard blank, which is obtained with at least one common reference benefit. At least one area of the reference blank that protrudes from the cardboard is folded around an edge of the cardboard onto the back.
  • the device comprises a joining device which positions the cardboard and the associated blank blanks relative to one another and glues them at least in certain areas.
  • the cardboard elements that together form a product are synchronously fed to the joining device from a cardboard feed upstream of the joining device in the product flow.
  • the cardboard feed has at least one transport section.
  • the cardboard supply can also include one or more cardboard magazines with appropriate separating devices.
  • the reference blanks are fed to the joining device by a transport section of the blank feed, each matching the cardboard.
  • the panel supply upstream of the panel transport section, the panel supply includes a separating device. This separating device separates one blank sheet from a supply such as a stack of sheets.
  • An adhesive application device is arranged on the panel transport path. This divides the supply of blanks into a first section upstream of the adhesive application and a second transport section downstream of the adhesive application. Seen in the product flow, this second section is followed by the joining device.
  • the adhesive application device is arranged in such a way that it applies adhesive to the adhesive side of the blank during the transport movement of the reference blank.
  • At least one wrapping device of a known type is arranged downstream of the joining device, which wraps overhangs of the reference blanks onto the back of the cardboard.
  • the device has a cutting device with at least one pair of tools in the area of the first section of the panel transport upstream of the adhesive application device.
  • the pair of tools penetrates the transport plane of the corresponding transport section of the panel feed. It is made up of a cutting cylinder and an anvil cylinder.
  • At least the cutting cylinder has a cutting edge that is raised relative to an outer cylinder surface.
  • the counter-cylinder can be designed as a counter-pressure cylinder without a cutting edge or also as a cutting cylinder. Both tools of a pair can each be rotated about an axis. The axes of rotation of a pair are aligned essentially parallel to one another and essentially perpendicular to the transport direction of the reference panel.
  • the cutting cylinder and the anvil cylinder of a pair are drivingly connected to one another.
  • the pair of tools is arranged in a common bearing block.
  • the storage of at least one of the tools in the common bearing block includes at least two eccentric bushings.
  • the rotational position of the two bushings in the bearing block determines the center distance of the tools in a pair.
  • the two eccentric bushings of the tool are located on the same side of each tool. In this way, pairs of tools opposite one another can be arranged on both sides of the transport path of the panel, as a result of which a compact design of the device is possible.
  • the two sockets of a tool are spaced apart from one another in the axial direction.
  • a drive element of the drive connection of the two tools of a pair is fitted between them.
  • This arrangement leads to a rigid tool storage.
  • the arrangement of the drive connection between the bearing points causes a reduction in the center distance in the area of the cutting edge, particularly when using spur gears as the drive connection under drive load. This counteracts the widening caused by the cutting forces.
  • At least one of the eccentric bushings is drive-connected to an infeed device, so that the rotational position of the eccentric bushing is determined by the infeed device. This allows the center distance within a pair of tools to be set in a simple and repeatable manner.
  • This infeed device preferably has a display element which makes available information that can be interpreted as the center distance.
  • a desired center distance can thus be set in a particularly simple manner.
  • the eccentric bushings can be fixed in their rotational position.
  • the infeed device preferably has a self-locking gear.
  • a worm drive which enables a very compact design of the infeed device, is particularly advantageous.
  • the delivery device includes a controllable drive, which is connected to the controller of the device by means of a data connection.
  • a controllable drive which is connected to the controller of the device by means of a data connection.
  • the eccentric bushings of a tool are preferably decoupled from one another with regard to their rotational positions, so that they can be adjusted individually. In this way, a parallelism deviation of the axes of rotation of a pair of tools can be adjusted in a targeted manner.
  • a setting in which the axes of rotation approach each other from the side of the tool facing the bearing to the side of the tool facing away from the bearing is particularly advantageous.
  • the tools of a pair can be clamped to one another in such a way that an undesired non-uniform widening of the center distance caused by the cutting forces over the tool width is compensated.
  • this prestressing of the pair of tools can also be adjusted in a simple manner in addition to the distance.
  • the cutting device comprises at least one sensor, which determines a value that can be interpreted as a force acting radially on the tool.
  • This sensor is preferably connected to the controller of the device by means of a data line.
  • the radial cutting force can be determined. If it increases, it can indicate tool wear.
  • Corresponding information can be displayed to the operating personnel.
  • the at least one pair of tools can be positioned essentially transversely to the transport direction of the reference panel.
  • the cutting device preferably has a parking or maintenance position for the pair of tools outside of the panel transport path. It is thus possible to disengage the tools without changing the center distance. This means that the eccentricity of the bushes is reduced and the center distance can be set more precisely.
  • an additional device for opening the pair of tools can be dispensed with and a compact and rigid construction can be made possible.
  • a simple transport device guides the finished book covers, box covers or game boards out of the device and makes them available for further processing.
  • An exemplary cover machine for the production of book covers 103, box covers or game boards includes as in 1 shown is a cardboard feed 1 with a cardboard feed direction g, a blank feed 2 with a separating device 3 and a blank feed direction b, a cover outlet 6 and several processing stations 4, 5, 7, 9.
  • the processing stations 4, 5, 7, 9 are in the direction of the product flow, respectively placed along panel feed 2 or between board feed 1, panel feed 2 and blanket outfeed 6.
  • An adhesive application device 4 is located downstream of blank feed 2. Its blank cylinder takes over blank 105 provided by blank feed 2 and guides it along an application roller into joining device 5. The application roller transfers the adhesive to blank 105. Adhesive is also applied, of course possible by one or more application nozzles not shown in the figures.
  • the blank 105 provided with adhesive is rolled onto one or more cardboard blanks 101.
  • the joining device 5 provides a stationary joining roller that rolls on the panel cylinder.
  • the one or more cardboard blanks 101 are made available to the joining device 5 from the cardboard feed 1 .
  • a plurality of wrapping devices 7 are arranged downstream of the joining device 5 in the direction of the product flow. These wrapping devices 7 each have a plurality of wrapping elements. The wrapping elements capture the overhangs of the panel blanks 105 in relation to the joined cardboard blanks 101 and wrap them around the outer edges of the cardboard blanks 101 down to the inside of the cover and press them on.
  • the export 6 is arranged downstream of the wrapping devices 7 . It takes over the finished covers, stacks them, guides this stack of covers out of the cover machine transversely to the benefit or cardboard transport direction b, g and makes them available there.
  • a cutting device 9 for cutting reference blanks 105 from the individual blank sheets 102 is arranged.
  • a first unit consists of circular shears 32. This is arranged as a longitudinal cutting device penetrating the blank transport plane B with its axes of rotation transverse to the blank transport direction b.
  • a controllable feed drive 30 enables the positioning of the circular shears 32 transversely to the panel transport direction b. In this way, panels of different widths can be produced from the same raw formats.
  • the lateral section is removed from the reference panel 105 and carried away by guide elements of a known type that are not shown.
  • each of these two cutting units can be positioned transversely to the panel transport direction b according to the reference panel width.
  • the cutting cylinder 11 arranged above the blank transport plane B is cylindrical with a hard cutting edge 24 that is raised relative to the lateral surface 23.
  • This cutting edge 24 is designed spirally in such a way that its processing on the blank transport plane B forms a diagonal cut.
  • the associated impression cylinder 12 is cylindrical with a smooth surface and is made of a softer material.
  • the end faces of the cutting cylinder 11 and impression cylinder 12 of the same pair of tools 10 are aligned with one another.
  • Both cylinders 11, 12 are accommodated in a common bearing block 13 by means of roller bearings 34.
  • Their axes of rotation 16, 17 are parallel to one another and aligned transversely to the panel transport direction b. Together, the axes of rotation 16, 17 define the tool plane C.
  • the cutting cylinder 11 is drive-connected to a servo motor 27 by a belt drive.
  • a gear 14 made up of spur gears 15 represents the drive connection between the cutting cylinder 11 and the impression cylinder.
  • Each of the roller bearings 34 assigned to the cutting cylinder 11 is accommodated in the bore 28 of an eccentric bushing 18 in each case. These are rotatably arranged in the bearing block 13 with their outer lateral surface 29 .
  • the rotational position of the bushings 18, together with their eccentricity e, determines the center distance a between the cutting cylinder 11 on the one hand and the impression cylinder 12 on the other.
  • a small eccentricity e allows a very precise setting of the tool pair 10.
  • Each eccentric bushing 18 is assigned an infeed device 19 for convenient operation.
  • a spindle drive 20 with a sufficiently small pitch allows very precise adjustment on the one hand and leads to self-locking on the other hand, so that unintentional adjustment during operation is avoided.
  • a display element 2 of the rotational position of the spindle is provided.
  • a controllable delivery device 19 with Spur gear shown is shown.
  • the controllable drive 22 can 3 in a delivery facility according to 2 be supplemented so that in both cases an automated setting is possible.
  • each eccentric bushing 18 makes it possible to position the axes of rotation 16, 17 of the tools 11, 12 in a targeted manner in relation to one another.
  • 3 shows a setting with an outer axis distance aa of the shaft end facing away from the cutting cylinder 11 and an inner axis distance ai on the free end face of the cutting cylinder 11.
  • the outer axis distance aa is greater than the inner axis distance ai due to the selected rotational positions of the eccentric bushings 18.
  • the spur gears 15 of the drive connection 14 of the cutting cylinder 11 and the impression cylinder 12 are each arranged between the eccentric bushings 18 .
  • the radial forces generated by the drive lead in the area of the drive connection 14 to an increase in the center distance due to bending.
  • the inner center distance ai is reduced. This arrangement thus compensates along with the preset skew according to 3 the increase in the inner center distance ai resulting from the cutting forces, such that the center distance in the area of the cutting edge 24 is constant.
  • All controllable drives 22, 27, 30 are connected to the controller 25 of the device by data lines.
  • a data memory 26 is assigned to the machine control 25 so that any stored production orders and the associated machine settings can be called up can be set automatically.
  • the tool pairs 10 can be brought automatically into the respective production position or a maintenance position 31 .
