Definitions

  • the present invention relates to a device for processing mainly flat workpieces with a device for aligning the workpiece in a processing position according to the preamble of claim 1, a machine for punching cardboard sheets according to the preamble of claim 7, a machine for erecting cardboard blank according to the preamble of claim 8 and a method for aligning mainly flat workpieces according to the preamble of claim 9.
  • the machine comprises a gluing device for applying liquid adhesive to these bevelled sides of the side members, with means for transporting the card blank into the gluing station along a linear conveying path.
  • a pair of guide rails laterally delimit the conveying path and prevent unintentional shifting of the cardboard blank transversely to the transport direction, by sliding the respective outermost edges of the cardboard blank along the guide rails.
  • stops are provided which determine the position of the cardboard blank within the gluing station in the direction of the conveying path. Slippage of the cardboard blank during adhesive application is prevented by clamping elements which fix the cardboard blank in the desired position.
  • a pair of application nozzles which are arranged one behind the other in the transport direction, traverse the cardboard blank across the conveying path and apply the liquid adhesive to the inclined sides of the side elements, which extend transversely to the transport direction.
  • both the stops and the application nozzles can be positioned in the transport direction.
  • the disclosure DE 197 29 529 A1 describes a machine for making books by hooking each book block into a book cover.
  • a machine for making books by hooking each book block into a book cover.
  • Arranged in an imbricated formation lying flat book covers with upwardly facing back occasionally pass through a device for bending the book covers and get in the further course of transporters pushed into a book cover folding and -back-shaping device.
  • the book cover is in the book cover folding and -back molding device in rest position.
  • the two book covers of the book cover are supported by their outer edge areas on angular alignment rails and with their inner edge areas on heated rails.
  • the book cover is guided during its transport in the book cover folding and -back molding device between the vertically arranged legs of the oppositely arranged angular Ausrichtschienen.
  • the width between these respective book cover receiving vertically arranged legs is so slightly larger than the width of the supplied book cover, on the one hand clamping the book cover is avoided in this guide, on the other hand, the book cover both parallel to the transport direction aligned as well as positioned transversely to the transport direction.
  • this leads to the book cover being uncontrollably and unevenly compressed by its sliding on and on the alignment rails in the fold area, which is not necessarily reinforced by an insert. Since the fold areas of the subsequently resting book cover do not relax independently, especially with heavy book covers, these positioning errors lead to quality reductions during folding creasing and spinal forms.
  • the transport rollers are made so slightly against the transport direction that they impose the cutting a transverse to the transport direction and on the alignment rail facing force component. In this simple way it is ensured that the blank during its transport with its adjacent the alignment rail outer edge and aligns.
  • a disadvantage is the necessary sliding of the blank on the transport rollers, in particular for sensitive surfaces of the blank substantially along its longitudinal extent. Also, the blank is impressed by the transport a moment about a vertical, which must be collected by the alignment rail and leads to unfavorable length-to-width ratio of the blank to unwanted rotation of the workpiece during transport.
  • the object of the invention is to provide a way to align flat workpieces of the type mentioned for further processing in a simple manner with improved precision.
  • the invention achieves the object by a device with the features of claim 1, by a machine for punching cardboard sheets with the features of claim 7, by a machine for erecting cardboard blank with the features of claim 8 and by a method with the features of Patent claim 9.
  • Advantageous developments of the invention are characterized by the features specified in the subclaims.
  • the alignment device comprises one or more movable alignment elements. These alignment elements each have a contact surface that comes into contact with the workpiece.
  • This contact surface is spaced in a starting position of the respective alignment element to the processing position of the processing device such that the workpiece can be moved by the transport device into the processing position, without coming into contact with the alignment element.
  • the alignment element initially moves in a relative movement such that its contact surface contacts the workpiece that has been brought into the machining position within one of its linear depressions.
  • the alignment element acts on one of the surfaces of the linear depression of the workpiece in such a way that it aligns the workpiece as specified within the machining position.
  • a movement path of the respective alignment element which can be subdivided into several sections, is advantageous.
  • a first movement section the alignment element is approximated from its starting position in a direction approximately perpendicular to the transport plane or the working plane of the workpiece in its processing position.
  • the alignment element with its described contact surface dips into the respective recess of the workpiece, without necessarily coming into contact with the workpiece.
  • a second movement section adjoins this first movement section, wherein its movement direction has at least one movement component perpendicular to the contact surface of the recess of the workpiece, which contacts the contact surface of the alignment element.
  • the actual alignment takes place from the contact of the workpiece by the alignment until reaching the required position and orientation of the workpiece by a direction of movement advantageously parallel to the direction of the alignment.
  • the movement components described can each describe linear movements or a common arcuate movement of the movement Aligning. In this way, unnecessary sliding of the alignment on the workpiece and thus undesirable resulting from friction influences such as. The stick-slip effect is avoided, resulting in a particularly precise and consistent exact alignment of the workpieces.
  • the sliding caused by the alignment of the workpiece in the working plane and any sliding of the alignment element on the workpiece can be effectively supported by mechanical vibrations.
  • the vibration generator required for this purpose can be arranged on an alignment element. Alternatively, the vibration generator may be attached to a member supporting the workpiece in the machining position.
  • the line-shaped depression of the workpiece can be a groove or a groove in a single-part or multi-part workpiece, for example a cardboard blank, or a gap between two elements of a multi-part workpiece, such as the fold region of a book cover.

  • a transport device 12 spends in each case a single board blank 2 in a direction opposite the horizontal transport direction 102 in a gluing device 50 and transports the cardboard blank 2 after applying the adhesive in the same direction 102 from the gluing device 50 in a device not shown for erecting the walls 6 a box.
  • the cardboard blank 2 rests on a plurality of support rails 18, which are parallel to the transport direction 102 and form the transport plane 101.
  • the transport device 12 has hold-down rails 14 in order to prevent unintentional movements of the board blanks 2 out of the transport plane 101.
  • a plurality of slides 15 are provided, which move clockwise and synchronously back and forth along the transport direction 102.
  • Each slider is mounted so pivotable that it dives under its return stroke below the transport plane 101. In this way, transport phases alternate with the resting phases of the cardboard blanks 2, in which their processing can take place.
  • a cardboard blank 2 moving slides 15 can be dispensed with lateral guide rails during transport.
  • two identical alignment devices 20 are provided, each with an alignment rail 21 arranged parallel to the transport direction 102 and above the transport plane 101, of which in Fig. 3 only the respect. Of the flow left side is shown.
  • the following Explanations to the alignment device 20 shown apply in the same way for the unillustrated, mirror-image alignment device.
  • the alignment rail 21 is displaceable both parallel to the transport plane 101 and pivotally received about an axis 104 parallel to the transport direction in a frame-fixed holder 23.
  • pivoting 108 of the alignment rail 21 this is attached to a rotatable about an axis 102 parallel to the transport direction 102 rotatable lever 22, which is actuated by a double-acting pneumatic cylinder 24.
  • the pivot axis 104 is arranged so slightly above the transport plane 101 and the lever 22 designed so long that the pivoting 108 of the alignment rail 21 about the axis 104 in a first, above the transport plane 101 starting movement section in about a vertical plane to the transport plane 101 Alignment rail 21 corresponds.
  • the alignment is achieved by the wedge-shaped cross section of the dipping into the V-shaped groove 3 alignment rail 21. Due to the corresponding Fig. 1 known angle 112, 113 of alignment rail 21 and groove 3 and the fixed end position of the alignment rail 21, the position of the cardboard blank 2 after the alignment is predetermined.
  • the described pivot bearing is in turn arranged on a linear guide 28 on the stationary holder 23 of the alignment device 20.
  • This linear guide 28 is oriented parallel to the transport plane 101 and perpendicular to the transport direction 102 and thus allows an independent of the described pivoting movement 108 of the alignment rail 21 transverse to the transport direction 102.
  • a compact, single-acting pneumatic cylinder 26 is provided which the Ausrichtschiene 21st in one direction 107 drives from the product center to the outer edge.
  • the provision in the opposite direction is carried out by horizontally acting compression springs 27.
  • the bottom region 5 of the cardboard blank 2 experiences a tensile load, which ensures a stretched position even with soft materials.
  • the gluing device 50 comprises an application nozzle 51 which is displaceable along a linear guide 52 which is oriented parallel to the transport direction 102 of the cardboard blanks 2.
