Definitions

  • the invention relates to a folding device for cardboard boxes in development, preferably for pizza boxes.
  • Such pizza boxes are usually at pizzerias in a settlement according to DE 199 01 237 A1 delivered to be folded by hand on site. Accordingly, depending on the number of pizzas delivered in day-to-day business, correspondingly folded cardboard boxes with a not inconsiderable space requirement must be kept in the pizzeria, which are then also opened by hand in order to insert the pizza and then to deliver it.
  • a device for conveying such a pre-folded packaging blank is previously known, with the help of which such flat pizza boxes delivered in the processing can be folded.
  • the pre-folded pizza boxes are loaded with the pizza on the one hand, which is placed on a bottom section of the pizza box and then folded around the pizza placed on the bottom element during the passage through the packaging machine, the pizza being for this purpose be conveyed horizontally through the packaging machine and its individual stations by means of a round belt conveyor.
  • Such packaging machines are used in production to to pack pizzas that are usually used frozen.
  • such a packaging machine cannot usually be used in a conventional pizzeria in day-to-day business.
  • the space required for the manually pre-folded pizza boxes in such a pizzeria is also quite considerable.
  • the invention is based on the object of creating a folding device, in particular for pizzas, which on the one hand has significantly less space requirements and on the other hand significantly reduces or eliminates the need for storage for pizza boxes.
  • the solution according to the invention eliminates the need to fold pizza boxes for later use and then to keep them available.
  • the invention comprises a folding device which has an angle frame, comprising at least two, at a distance from one another which corresponds to at least the width of the cardboard box to be fed, arranged angle elements, each having an adjustable foot on which, preferably at right angles , in each case a vertical strut is articulated, are built up, with a magazine frame open on the side face facing the vertical struts, which is at least through the vertical struts , the installation surface, the belt drive and at least one of the two vertical struts molded hollow tube, which is preferably arranged on the top of the installation surface, and into which an at least substantially L-shaped plug tube is inserted such that this hollow tube and the plugged in tube, the vertical cardboard boxes at least partially encompassed, preferably equipped with side plates, with a belt drive, preferably an electric motor-driven belt drive, assigned to the installation surface in such a way that a vertical, foremost cardboard box accommodated in the magazine frame, ie the cardboard box lying on the belt drive , a
  • the device according to the invention has the advantage that it is also suitable for holding at least a portion of the cardboard boxes required in day-to-day business within the explained magazine frame.
  • the frame element consists of a hollow tube lying on one side of the stack of cardboard boxes, which is attached to the vertical struts of the folding device, into which an angled plug-in tube is inserted, which surrounds the cardboard boxes at least in sections on the side facing away from the angle element.
  • the plug-in tube inserted into the hollow tube is also connected to this hollow tube by means of an internal spring element, the spring force of which presses the plug-in tube in the direction of the angle element and thus against the belt drive with the cardboard boxes in between. This ensures that when the belt drive is switched on, the foremost cardboard box can be moved downwards within the folding device while overcoming the frictional forces.
  • the plug-in tube is encased at least in sections by a buffer element in the pressing area against the rearmost cardboard box facing away from the angle element, so that damage or deformation of the cardboard boxes received in the magazine frame is avoided.
  • the mounting surface of the magazine frame is sloped downward in the direction of the belt drive, so that the propulsion of the cardboard boxes received in the magazine frame in the direction of the belt drive is supported by the incline brought about by this.
  • Both the electric motor-driven belt drive, the folding frame and the folding tools mentioned are each activated or deactivated and controlled by means of an operating element attached to the underside of the installation surface of the folding device.
  • an electric motor-driven lever element is also arranged on the two-sided adjustable feet of the folding device, which can be used as lid closers at a later point in time during the process of folding the cardboard boxes.
  • this cardboard box arranged vertically on the aforementioned installation surface is received in the folding frame.
  • the lateral folding tools arranged on both sides of the folding frame are each pivoted by 90 ° in such a way that they then rest against the bottom surface of this cardboard box facing away from the vertical struts of the folding device, with the lateral folding tools then pivoting further in the direction of the vertical struts so that the two sides over the outer frame of the Folding frame protruding lateral tabs of the cardboard box, preferably along a fold line embossed in the cardboard box at an angle of at least approximately 90 °, that is to say erected in relation to the bottom surface of the cardboard box.
  • the lower folding tools are now also pivoted by 90 ° and thereby preferably bent over again at an angle of 90 °, preferably along an embossed kink line running parallel to the erection edge of these cardboard boxes, a lower cardboard flap arranged at the erection edge away from the underside, and then bent over again by means of a further rotation of the lower folding tool along a preferably also embossed kink line, which is less distant from the lower erecting edge and runs parallel to the erecting edge, again bent at an angle of 90 ° to form a double wall.
  • the pizza box is unfolded into its later spatial shape.
  • the now pre-folded cardboard box is moved from its previous vertical position into a horizontal position by means of the pivotably linked folding frame.
  • the lid closers which are pivotably hinged to the adjustable feet on both sides of the box and which are in engagement with the section of the box provided as the lid element of the box, are pivoted from a horizontal position by 90 ° into a vertical position and thereby move the lid element in such a way that the Box is open.
  • the lid closers arranged on both sides of the box are each equipped with an angle element at the end in such a way that the side and front flaps of the cardboard boxes are also pivoted by 90 °, preferably along pre-stamped crease lines, at the same time as the lid closer is pivoted, i.e. they are erected against the bottom element of the box.
  • the folded box is then with the lid open inside the folding frame arranged between the adjustable feet. In this position, a pizza or another dish can now be inserted into the opened box.
  • the lid closers arranged on both sides of the box then carry out a further rotary movement, preferably by 90 ° in a direction facing away from the vertical struts of the angle element, so that the box is closed as intended.
  • the filled box can now be removed from the folding device, whereupon the lid closers can again be pivoted a total of 180 ° back to the starting position before another box is moved into the folding frame by means of the belt drive and the folding process described above is carried out again .
  • the invention further comprises a folding device, which has an angle frame, comprising at least two, at a distance from one another which corresponds to at least the width of the cardboard box to be fed, arranged angle elements, each having an adjustable foot on which, preferably in the right Angle, each a vertical strut is articulated, are built up, on these vertical struts at a distance that corresponds to at least the width of the cardboard box to be fed, in each case away from the base of the folding device, a magazine frame open on the side face facing the vertical struts, which at least through the Vertical struts, the mounting surface, the belt drive and at least one of the two vertical struts molded hollow tube, which is preferably arranged on the top of the mounting surface and into which an at least substantially L-shaped plug-in tube is inserted in such a way that this Hohlr ear and the inserted plug-in tube, which at least partially encompasses vertical cardboard boxes, the installation surface being a belt drive, preferably a belt drive driven
