Definitions

  • the invention relates to a device for on-line control and for the automatic ejection of wrong and / or faulty folding box blanks in the production of folding box cartons according to the preamble of claim 1.
  • Folding boxes made of cardboard or the like material represent a significant share of the packaging materials on the market in the packaging industry. This is not only based on the food industry with its diverse carton designs or the electrical and electronic industry, but also to a particularly high degree on the pharmaceutical industry. Both those in jars or other airtight containers and those in foil packaging are put on the market Pharmaceuticals are generally available in portions in folding box cartons, the imprints of which are immediately legible or in coded form provide information about the contents of the box.
  • the requirements regarding a large amount of information are particularly important for folding box cartons for the pharmaceutical industry and are largely precisely defined by a large number of laws and government regulations .
  • the optical, mechanical and / or electronic monitoring means that are able to detect defective or incorrect production parameters or product components with as little delay as possible, in order to remedy any errors immediately or to eject defective products from online production without interrupting production.
  • optoelectronic bar code readers, glue track control detectors and similar monitors are integrated into a high-performance folder gluer, which is only part of the automatic production line. This monitors the multiple folding of the flat blank into a six-sided or versatile container and the final gluing for the permanent assembly to the desired container shape in each manufacturing step.
  • a so-called rotary ejector in the form of a turntable is known Folding carton gluing machines (DE 37 43 728 C2).
  • this blank is taken by magnet-controlled switching rollers, taking into account the delay time or the number of boxes between the recognition and the passage of the blank to be removed from the rotary ejector, fed to a rotating ejector disk and taken over after being taken along ejected an undetermined angle of rotation in the tangential direction. Since the detection detectors are installed very differently in relation to the ejector in the production process, the delay times between detection and activation of the ejection device must be set according to the respective arrangement.
  • the turntable of the known ejection device is arranged laterally to the conveying path of the blanks and aligned in their plane so that the peripheral region of the disk lies directly below or above the path of movement of the blanks along their conveying path or overlaps them.
  • the blanks run into the folding box gluing machine individually, that is to say at a predetermined distance.
  • the position of the blanks is defined by non-slip engagement between the upper endless belt and the lower endless belt of the conveyor line.
  • the blanks protrude on both sides of the belt conveyor, so that the wrong or faulty blanks can be gripped during production by means of the mechanism of the rotary ejector.
  • the gripper is a friction roller that is activated when the wrong blank runs past the rotary plate of the rotary ejector, the edge of the blank onto the plate surface provided with a friction layer presses and pulls out the blank between the two endless belts of the conveyor line.
  • the friction roller When the friction roller is activated, the continuously rotating turntable thus detects a blank which is recognized as faulty at the moment of passing and converts its linear movement into the rotary movement of the turntable during production. However, this is only ensured if the box is held correctly during its lateral displacement. Otherwise, there can only be an undefined lateral shift without complete removal.
  • the rotational movement of the defective blank not only requires certain pressure and friction values, but also a distance between the successive blanks in the conveyor track, which must correspond at least to the difference between the diagonal length of the blank and its width. This places special demands on the separation of the blanks, ie the spacing of the individual blanks from one another, which lead to a reduction in the production output of the entire machine system.
  • the angle of rotation, over which the defective blank is carried by the rotary plate of the rotary ejector is not defined, since it depends not only on the size, but also on the surface quality and weight of the blank, which results in very different friction Driving forces and torques can result.
  • the uncontrolled discharge direction that cannot be prevented in this way often causes machine malfunctions, which can lead to a further reduction in the production output of the overall system.
  • the for taking a defective one The required frictional connection between the activated friction roller and the turntable over different arc lengths, depending on the dimensioning of the blank, is only ensured for certain dimensioning areas in the blank dimensions and its box thickness, depending on the adjustment of the rotary ejector. It has also been shown that when the production speed along the conveyor line is increased, the blanks between the friction roller and the turntable are not always reliably grasped. Such blanks can then be partially moved and partially rotated from the ongoing production, so that there are ultimately malfunctions that result in the shutdown of the entire automated on-line system.
  • the present invention comes in, which is based on the object of specifying an ejector for at least partially automated on-line production systems for producing folding box cartons from corresponding blanks, in which any swiveling or deflecting or rotating movement of the one to be removed from the production line Cutting is avoided, so that the disadvantages caused by this are eliminated and the hitherto required increased demands on the operating personnel of the machines can be dispensed with with reliable sorting out.
  • the ejector according to the invention for blanks in the manufacture of folding box cartons only carries out translatory movements instead of the previously required deflection or pivoting movements with the blanks to be eliminated in each case, the distance between the blanks fed on the linear conveying path can also be minimized in the shingled stream and thus the production speed increase.
  • the blank is ejected in a controlled manner with a precisely defined ejection direction and removal speed via a linear conveyor in the given conveyor level.
  • the detection of defective blanks is independent of their thickness, their surface properties as well as their size and weight.
  • the trouble-free ejection is achieved according to the invention by the synchronization of the speed of the linear conveying path of the blanks along the production line on the one hand and the linear speed of the ejection device which conveys in the same plane to the direction of production on the other hand.
  • the coordination of the two speeds with one another is only dependent on the angle which is defined between the two linear movements in the same plane, as described above. Once the system has been set up, the angle is generally not changed.
  • the conveyor section 3 consists of a double belt arrangement, that is to say two endless conveyor belts lying one above the other at a close spacing, which rotate at the same speed in the direction of the arrow and hold the individual blanks 4 in a defined manner by friction.
  • a fixed rail arrangement 9 with a conveyor belt 6 for removing defective blanks 4 'in the form shown is positioned in the conveying plane, the ejector belt moving in the direction of the arrow the speed V2 moves.
  • This gripper mechanism (not shown in more detail in FIG. 1) detects the blank 4 'at the beginning of the linear ejector, which is arranged such that its area 10 adjacent to the conveying path 3 is flush below or above the edge area of the blanks 4, the conveying plane of the linear ejector 6 , 8, 9 lies in the conveyor plane of conveyor section 3.
  • the section overlapping in plan view between the area 10 of the linear ejector 6, 8 9 and the respective edge area of a blank 4 is designed in such a way that no contact disturbances for the blanks 4 can occur along the conveying direction of the on-line system. Only in the event that a blank is recognized as incorrect, defective, incorrect or incorrectly printed by one or more signaling detectors, not shown here, is a gripper mechanism 7, 8 activated at the moment this blank 4 'passes the linear ejector, which blank either indirectly by friction on the area 10 or pushing it further by linear movement onto this area until it is taken along in the direction of movement and in the same movement plane of the linear ejector with only translatory movement at the speed V2.
  • the direction of transport between the conveying path 3 and that of the linear ejector according to the formula are coordinated.
  • the conveyor belt 6 of the linear ejector thus rotates at a higher speed than the production speed predetermined by the conveyor section 3, depending on the angle of attack ⁇ .
  • This results in a linear ejector, which is set at an angle ⁇ 45 ° to the conveyor section 3 to this side, for example, a linear ejection speed V2 of In this exemplary embodiment, the ejection speed is thus 1.4 times greater than the conveying speed of the blanks 4 along the production line.
  • FIG. 2 and 3 show, for example, embodiments for possible ejectors of defective blanks 4 'from the conveyor section 3.
  • a plunger 7 which can be moved back and forth in translation in the direction of the double arrow, is activated when one is not
  • the measuring and testing device shown ie a suitable code reader, has previously recognized a faulty blank 4 'and a Corresponding signal for the actuation of the ram, taking into account the delay time between detection of the error and passing of the faulty blank on the linear ejector.
  • the shown activated, ie extended, position of the plunger 7 is at most only available for a fraction of the length of passage of a blank, calculated to the smallest possible blank length.
  • the plunger In the non-activated position, the plunger is withdrawn outside the range of movement of the cutting sequence.
  • the defective blank 4 'pushed into the gripper area of the linear ejector by means of the plunger 7 is gripped by this and with the increased speed V 2, which corresponds to the projection speed, taking into account the angle ⁇ in the direction of the conveying movement, the speed of the conveying path 3, essentially in the conveying plane remaining, carried and ejected in the direction of the slide rail 9.
  • the plunger 7 thus pushes the defective blank out of the transport direction so that it inevitably runs into the laterally inclined ejection belt and is slid out of the rail 9 by friction with this belt.
  • the inlet section 19, ie the section 8 of the ejector belt 6 adjacent to the conveyor section 3, is designed to be pivotable, so that it can be moved in the direction of the blank 4 'and, as shown, away from it.
  • This pivotable section 8 is pivoted downwards for the ejection of a defective blank 4 'until it cuts the blank between itself and the low-friction surface of the slide rails 9 or a corresponding guide plate jammed and thereby pulling the blank out of the conveyor section 3 by means of a force-locking coupling.
  • the linear conveyor consists of the endless belt 6 'rotating at the speed V2, which is driven by the motor 11, and the low-friction coated guide rail 9.
  • the linear conveyor can consist of two endless belts revolving at a close spacing from one another, corresponding to the conveying path 3, which according to FIG. The endless belts, as it were, clamp the blanks 4 between them.
  • Fig. 4 shows the linear conveyor designed according to the invention in a side plan view in more detail.
  • the endless belt 6 ' which ejects a defective or faulty blank is therefore guided in the region of the pivotable section 8 according to FIG. 3 on the one hand around a folding roller 16 and on the other hand around a deflection roller assigned to the motor 11.
  • the lower run of the discharge belt 6 ' is defined in terms of position by a plurality of support rollers 21 arranged at a distance from one another. A distance can be set in a defined manner between the lower run and the slide or guide rail 9, the adjustment of which can be carried out as a function of the thickness of the blanks.
  • the surface of the slide rail 9 is treated in such a way that it does not allow any friction with the blank, while the surface of the ejection belt 6 'should have the highest possible coefficient of friction compared to the blank to be ejected.
  • the ejecting belt 6 'could advantageously be pre-tensioned via the tensioning roller 20, which is mounted on the free pivotable end of a tensioning lever 14 - in such a way that the folding roller 16 is held in tension in its two positions, namely a lower ejection position (not shown) and the illustrated inactive position is.
  • the folding roller 16 is firmly connected to a pivot rod 15 by means of the folding lever 13 and can be pivoted together with the latter about a pivot point.
  • the pivoting process takes place by means of an electromagnet 17 via its actuating plunger 22.
  • a plunger roller 24 is mounted, which engages in a fork bearing of the free end of the pivot rod 15.
  • the stroke of the actuating plunger 22 for specifying the passive and the activated position of the folding lever 13 can be precisely specified by loosening a lock nut 18 by means of the adjusting screw 19.
  • the tension of the ejection belt 6 'set with the tensioning roller 20 must be increased above a maximum value is carried out in order to be subjected to the output voltage again in the ejection position.
  • the activated ejection position (not shown), the relevant section of the endless belt 6 'lies in parallel with the lower guide rail in accordance with this and is aligned with the entire lower run of the belt.
  • the folding lever 13 and the pivotally connected to this, but pivotable about a common pivot rod 15 are shown in Fig. 4 with dash-dotted lines in the position in which the ejector belt 6 'can be mounted or removed from the linear ejector without tension.
  • a cover 23 encloses the non-pivotable part of the linear ejector.
  • the electromagnet 17 is designed as a double magnet, ie return spring forces are not required, which leads to an additional reduction in the required switching times. These mechanical measures and the pulsed activation of the two electromagnets with a defined overvoltage (fast excitation) lead to very constant switching times in the ms range. In addition, the switching time is tracked exactly depending on the conveying speed by an electronic compensation circuit.
