Definitions

• the invention relates to a folding box adhesive machine for producing folding boxes from blanks, with a folding station in which the blank parts provided with an adhesive strip are folded, an adjoining transfer station which, as a conveying device, comprises at least two pairs of requesting elements, each consisting of an upper and lower belt, and one Has device for discharging defective boxes, and with a collecting and pressing device in which the flat-folded boxes are pressed to set the adhesive
• the discharge device in the transfer station serves to discharge incorrectly detected boxes in front of the collecting and pressing device before a shingled stream is produced from the boxes at the beginning of the collecting and pressing device.
• the boxes are still required individually and at a distance from one another by the transfer station, so that a single box can be pulled out without affecting the preceding and following boxes.
• Defective boxes are boxes that are not adequately glued, boxes that contain folding errors or boxes that were identified during an identity check as not belonging to the order
• Such a generic folding box gluing machine is described in the brochure "Diana 1 15-3 Diana 125-3, the universal folding box gluing machines" of the applicants.
• the machine described has an ejector as an additional device, which is installed as a pre-assembled unit in the transfer station and boxes - throws that were recognized as faulty
• the ejector to eject the faulty cling boxes is arranged on a long side of the machine. It contains a pinch roller arranged on a turntable, from which a defective box is packed on its part protruding from the outside of the belt pair and pulled out of the machine
• the invention is therefore based on the object of improving a generic folding box lifting machine in such a way that defective boxes of large width can be removed from the machine
• the discharge device constructed in accordance with the invention has the further advantage that boxes with long flaps which are not folded in and which are not covered can also be discharged. If such boxes are pulled out as a whole only on one side, there is a risk that a conveyor belt will be removed from the box from its guidance This is due to the fact that the inwardly folded, uncovered long flap opens on the opposite side as soon as it is pulled out between the first pair of conveyor belts and meets the second pair of conveyor belts in the open state and entrains its upper belt
• Long knives which are arranged on the inside next to the pairs of conveyor belts, divide the box into three parts.There are two narrow side parts that can be easily pulled out to one side, and a central part that is led down between the pairs of conveyor belts.
• the division into three Parts has the advantage of both extremely wide boxes and boxes with many To be able to discharge individual parts, for example folding bottom boxes.
• the two longitudinal cuts can be made so that all box parts that could cause problems when pulling out on the straps remain on the middle part and are thus discharged downwards
• the design of the long knife as a circular knife according to claim 3 makes it possible to cut even thick boxes made of cardboard or corrugated cardboard with a high weight per unit area
• Figure 1 shows a schematic side view of the individual stations of a folding box gluing machine
• Figure 2 shows a perspective view of part of the transfer station with the discharge device
• the folding boxing machine begins with an insert 1, which pulls the blanks to be processed from a stack at high speed one after the other and feeds them individually to the subsequent processing stations
• Exemplary embodiment has a two-stage design.
• the primary crusher 2 contains folding elements to fold and unfold folding flaps so that the corresponding longitudinal lines are made soft and supple by kinking by 180 °.
• the two-stage embodiment enables more longitudinal and transverse lines to be broken and additional ones
• the folded boxes are checked for folding errors.
• photocells are arranged in this area, from which the length of the box is scanned. If the length of the folded box does not correspond to the specified format, for example because a flap has not been folded properly, then This box of the central control unit of the folding box gluing machine was also reported as defective
• the transfer station Directly adjacent to the folding station 3 is the transfer station 5, which is shown enlarged in FIG. 2.
• the transfer station has the primary task of feeding the folded blanks, which have not yet been bonded with adhesive seams, in all parts precisely aligned to the subsequent collecting and pressing device 6 Transition from the transfer station 5 to the collecting and pressing device 6, a shingled stream is produced from the folded boxes.
• the collecting and pressing device 6 has press bands by means of which the adhesive seams are held under pressure until the adhesive has set securely
• the transfer station 5 contains, as a conveying device for the folded boxes, two pairs of belts that extend parallel and at a distance from one another in the conveying direction, each consisting of a lower belt 7 and an upper belt 8.
• the folded blanks are between the upper runs of the lower belts 7 and the lower
• the straps of the upper straps 8 are spaced apart from one another, the upper straps 8 holding down the folded-over side tabs of the blanks.
• the pairs of straps 7, 8 must be able to be positioned transversely in order to adapt to different blanking widths mounted, which is suspended transversely positionable in the machine frame by means of an adjusting spindle.
• each upper conveyor belt 8 is mounted on a so-called roller rail 10, which are each displaced transversely synchronously with the associated roller cheek 9 in order to achieve the desired one Adjusting the working position of the belts 8
• the belts 8, 9 are driven by the central drive of the folder gluer
• the transfer station 5 contains a discharge device which discharges from the folding-box gluing machine as defective boxes 11.
• the structure and mode of operation of the discharge device are shown in FIG.
• the discharge device contains at least one knife 12 that cuts in the direction of travel, which is arranged at the beginning of the transfer station 5 between the two pairs of feeders 7, 8.
• the knife 12 is mounted in the frame of the transfer station 5 so that it can be raised and lowered so that it can be cut into the The level of the boxes 1 1 can be lowered and raised from the level for deactivation
• Two identically constructed knives 12 are preferably arranged on the inside next to a pair of conveyor belts 7, 8, of which a defective box 11 is divided into three parts 11 1, 11 2, 11 3
• the knives 12 are preferably freely rotatable circular knives which are mounted in a protective housing 13 and are moved downward for cutting against a counter roller 14.
• Each counter roller 14 extends circumferentially from below to the height of the upper, demanding run of the lower conveyor belt 7 and thus supports a box 1 1 when cutting from below
• the protective housing 13 of the circular knives 12 are each fastened to the associated upper roller rail 10. They can each be pivoted outwards into a parking position if they are not required.
• the protective housing 13 is therefore each on one Lever 15 attached, which can be pivoted outwards on the respective roller rail 10 and at the same time is cross-adjustable in order to be able to change its relative position to the pair of belts 7, 8
• the respective protective housing is via its fastening lever 15 13 automatically positioned with the knife 12 during a format change with the roller rail 10.
• the left protective housing 13 is shown partially open in FIG. 2 in order to show the fastening of the knife 12 within the housing 13.
• the knife 12 is fastened to a holder 16 which is fastened by means of a pneumatic piston-cylinder unit can be moved vertically over the required stroke in order to move the cutting edge of the knife 12 against the counter roller 14
• a device for laterally pulling out the side parts 11.1, 11.3 that were cut during the longitudinal cut from the machine At a distance behind the knives 12 on each longitudinal side of the transfer station 5, there is a device for laterally pulling out the side parts 11.1, 11.3 that were cut during the longitudinal cut from the machine.
• Each of the devices has a belt conveyor 17 which extends from the outside through a recess in the upper roller rail 10 to the vicinity of the conveyor belts 7, 8.
• each belt conveyor 17 extends approximately at an angle of 45 ° to the conveying direction of the pairs of belts 7, 8 towards the outside above a smooth table 18 which is fastened to the outside of the roller cheek 9.
• the upper surface of the table 17 forms a counter surface for the lower run of the belt conveyor 17 suspended from the upper roller rail 10, on which a box part 1 1.1, 1 1.3 is discharged to the outside.
• the front deflection roller 19 of the belt conveyor 17 can be raised and lowered by means of a pneumatic piston-cylinder unit 20. When the deflecting roller 19 is lowered onto a box part 1 1.1, 1 1.3 which projects beyond the conveyor belts 7, 8, the belt pulls the box part 1 1.1, 1 1.3 outwards over the table 18 and removes it from the machine.
• the belt conveyor 17 is deactivated by lifting the front deflection roller 19.
• it is suspended in height-adjustable manner on a support arm 21 which is attached to the upper roller rail 10.

If a box 11 is detected as being defective, the central control unit of the folding box gluing machine determines the point in time at which this box 11 enters the transfer station 5.
• the knives 12 are lowered and cut the box 11 into three parts 11.1, 11.2, 11.3 during the passage. If a faultless box follows, the knives 12 are raised to their inactive position again immediately after the box 11 has passed through. With a corresponding delay, the two belt conveyors 17 are then placed on the parts of the box parts 11.1, 11.3 protruding outside between the conveyor belts 7, 8 while the belt drive is switched on. The belt conveyors 17 pull the box parts 11.1, 11.3 out over the table 18 out of the machine.
• the belt conveyors 17 are preferably set so that their angle to the conveying direction is 45 °, and their speed is increased to V 2 times the conveying speed. The speed of the belts 7, 8 is set.
• a single knife can be arranged between the pairs of conveyor belts 7, 8 if the box shape to be processed permits this, for example if the box 11 is so narrow that the parts produced during a cut can be easily removed from one side of the Machine can be pulled out
• the arrangement of two knives 12 can also process box shapes that contain box parts that cause problems when pulling out on the side of the conveyor belts 7, 8.
• the two longitudinal cuts can then be made so that all box parts attached to a belt 7, 8 have been butted, remain on the central part 1 1 2 and are thus discharged downwards. Even complicated box shapes, in particular folding-bottom boxes, can be easily removed from the machine
