Definitions
- the invention relates to a device for processing a blank that is conveyed along a conveying path at a predetermined conveying speed according to the preamble of claim 1.
- the invention relates in a special embodiment to a folding machine for producing a folding container from a blank conveyed along a conveying path at a predetermined speed, the middle part of which has laterally arranged hinge-like folding grooves on which side parts sit, which are raised by means of turning devices in the course of the conveying path from an initially spread position along the fold grooves are increasingly pivoted inwards towards the longitudinal center of the blank and finally folded together from above and connected to one another.
- the terms “device for processing a blank conveyed along a conveying path with a predetermined conveying speed” and “folding machine” are always used synonymously, since all the features underlying the invention match both in such a device and in such a folding machine.
- the present invention generally starts from a folding machine for producing folding containers from flat material blanks, the present invention relates in a preferred embodiment to folding machines for producing folding containers made of folding cardboard.
- folding machines for producing folding containers made of folding cardboard.
- corrugated cardboard blanks are to be used as starting materials.
- folding cardboard blanks only from corrugated cardboard is not intended to be hereby, however. Therefore, in the following, unless expressly stated otherwise, the materials corrugated cardboard, folding cardboard are treated synonymously, in particular the term folding cardboard also includes the general term folding container, provided that the folding container is produced on a folding machine in the sense of this invention.
- Such folding cardboard blanks exist for. B. from corrugated cardboard.
- a corrugated cardboard sheet is folded parallel to the shaft for each folding carton where the side flaps are to be hinged on the middle section.
- folding machines are also suitable for the production of envelope-like folding containers.
- These are e.g. B. protective coverings without a lid and / or without a bottom.
- protective coverings of this type there is the problem that the object picked up must fit as precisely as possible into the interior of the protective cover. Eliminating the bottom and / or lid means that there is otherwise a risk of slipping out unintentionally.
- a practically relevant case occurs e.g. B. in the coating of motor vehicle headlight reflectors. These reflectors are usually placed in corrugated cardboard envelopes. The inside dimension of the envelope is so narrow that the reflector is held in it.
- Another application example is, as I said, folding cardboard blanks that correspond to a developed rectangular box with bottom and lid. Such boxes are usually processed further on packaging machines. For this reason, the quality of the product leaving the folding machine is of particular relevance.
- Such a folding cardboard blank can also be provided with the necessary slots or recesses.
- the corrugated cardboard sheet is parallel to the area in the fold grooves
- the slot width is approximately z. B. 1 cm.
- the slot depth corresponds to the folding length of
- a fourth slot is created in the area of the two side flaps which are folded together and are to be connected to one another.
- One of the two side flaps also has a so-called binding margin or glue margin. It is a tab on which a fold groove is also provided.
- the fold grooves in any case form the hinges between the side flaps and the middle part.
- Usually four fold grooves are provided for cuboid boxes, in each case one fold groove is provided on both sides of the middle part, and one fold groove within the middle part and one fold groove in the region of the two folded side flaps.
- the pre-cut blanks, if any are now conveyed, while at the same time either the fold grooves are incorporated into the blank or, in the case of fold grooves which have already been prepared, the side flaps which are still spread out are gripped and folded in the course of the conveying path. Folding takes place in a manner known per se by means of so-called reversing belts, which first grip the side flaps from below.
- the turning belts run from one level below to one level above the middle part.
- the axes of the reversing belts are interlaced in such a way that the belt surface facing the folding cardboard blank turns by a total of 180 degrees along the conveying path.
- two such reversing belts are therefore arranged one behind the other on each side of the middle part, of which each reversing belt is only folded by 90 degrees.
- the problem on which the invention is based is to keep the inside dimensions of all the folding cartons of a lot produced on a machine within the narrowest possible tolerances.
- the object is achieved in the known folding machine in that, at least in the front region of the conveying path, there is provided a folding device which engages above and below the blank in such a way that a folding edge running in the longitudinal direction of the folding groove lies linearly in the folding groove on the top of the blank that a support zone corresponding to the folded edge is formed on the underside of the blank, and the folding device is driven synchronously with the conveying speed.
- the invention is based on two embodiments, with which different approaches to solving the problem are taken with matching device features.
- the advantage of the invention is that, irrespective of the width of the folding groove, a folding edge between the side flap and the middle part that is precisely positioned in the millimeter range and runs with the speed of the blank is offered for each side flap.
- the processing takes place statically according to this invention. This not only eliminates the harmful dynamic and difficult to predict influences, but also produces excellent qualities at high speed.
- each side flap in addition to the line-shaped clamping of the blank, each side flap is folded inwards.
- the folded edges offer the side flaps swiveled in from the outside, for example by means of the reversing belts, to support the folded area from the inside, on which the swivel movement is forced with millimeter precision.
- the invention makes use of the fact that corrugated cardboard blanks of this type, based on the basic dimensions of the blank, are always folded at matching locations. However, these fold grooves have a certain width, e.g. B. of about 1 cm.
- the fold groove width is understood to mean the width in the blank that is usually produced by so-called pre-squeeze rolls.
- the Zu cuts in the gap between opposite rolls. These rolls are very close to each other, which is less than the cutting thickness.
- the blank is thus squeezed to be prepared for the subsequent installation of the fold groove. This creates a certain fold area, in which the actual hinge axis will then lie.
- the actual hinge axis is only somewhere within the width of the groove.
- the folding device as a separate creasing station eliminates this disadvantage by precise, linear clamping of the blank over the entire blank length when creasing.
- the folding device together with a turning device eliminates this disadvantage by precise linear clamping of the blank during simultaneous inward pivoting movement of the side flaps.
- All embodiments of the invention include the linear clamping of the blank by the folding device.
- the clamping lines can also be realized in that the folding edge and the corresponding support zone act on the blank in the manner of a pair of scissors or a punch.
- corrugated cardboard depending on the shape of the corrugation in the groove, had an unintended and unpredictable shift in the actual folding zone.
- the fold zone always occurred where the folded cardboard blank happened to have the lowest bending stiffness.
- the invention differs significantly from this in that the linear clamping of the blank takes place statically on the blank, specifically over the entire blank length.
- the scoring is thus carried out by a static displacement over the entire cut length.
- the displacement can therefore only take place laterally and not, as in the case of opposing rollers, also in or against the conveying direction.
- the free ends of the folding swords can also not be clamped in place, since in the area of the free ends the side flaps must lie closed on the middle part in order to be able to glue them there.
- the invention deviates completely from this known teaching.
- the invention has recognized that a considerably increased accuracy can be achieved solely by the precise application of the fold groove or by precise initiation of the folding process with a folding zone defined to the millimeter.
- the folded creases are inserted into the blank when they are spread out.
- the side flaps are pivoted inward from the extended position at least 50 degrees during the clamping of the blank.
- the provided folding device enables the exact positioning of the later folding zone in the fold groove before the start of the folding process, regardless of the respective cross-sectional structure of the carton blank in the area of the fold groove.
- the folding device engages directly in the fold groove.
- the shaft lying between the cover layers of the corrugated cardboard is flattened out so that one can speak of a cross-sectional structure that is uniform for all folding grooves.
- the folding edges of the folding device also extend along the conveying path to such an extent that the folding zones can no longer move on the remaining conveying path.
- the side flaps are still widely spread on the front area of the conveyor path.
- the folding device is also on the end, ie. H. conveyor path waste, to be clamped so that the exact position of the folding edge in the folding groove is identical for all folding cartons produced on a folding machine.
- the folding device according to the invention is driven by a synchronous drive at a conveying speed such that the processing on the carton takes place at the conveying speed of the carton. It is advantageous to avoid any slippage, so that static conditions can actually be assumed at the cut.
- the folded edges are preferably realized by circumferential end loops, the chain links of which point in the fold grooves with puddle-like or eteg-like extensions.
- Such end loops are driven synchronously at the conveying speed.
- the sheet-like extensions with their outer sides facing the side flaps form an angle of no more than 90 degrees, preferably no more than 70 degrees, with respect to the plane of the middle parts.
- the side parts have approximately the space between the side flap and the middle part, which is increasingly smaller due to the side flap swung inwards, and is optimally used and, on the other hand, a high proportion of the pressing force exerted on the folding carton cut brought.
- claims 6-9 provide a further improvement in production accuracy and serve, in particular, to pivot the side parts of the blanks inward only by those pivoting forces which are not only the same size and rectified between the front contact point and the rear contact point between the side part and the reversing belt attack essentially with respect to the fold grooves on the side parts such that the side edge of the side part to be pivoted inward is held parallel to the fold groove while the pivoting movement is impressed on the side part.

- FIG. 7 is a detailed view of a folding device with an endless chain of paces (horizontal running plane),
- Figure 8 is a schematic view of a folding machine with creasing station.
- FIG. 1 show a folding machine 1 for producing a folding container.
- a folding machine consists of a central conveyor belt 2 which rotates endlessly at conveyor speed 3.
- the outwardly facing belt surface of the conveyor belts 2 offers a support surface for a folding carton cut 5.
- This folding carton cut lies on the central conveyor belt 2 and is carried along by feet 4 connected to the conveyor belt in the conveying direction 3.
- Such a folding carton cut has a central part 6 with which it rests on the central conveyor belt 2.
- Both sides of the middle parts and a fold grooves 7 arranged ecitically.
- the fold grooves are identified here with double dashes running and interrupted in the longitudinal direction.
- the fold grooves 7 lie parallel to the conveying direction 3 and represent hinge-like connections between the middle part 6 and the respectively attached side part 8.
- the side parts 8 can be pivoted inwards with respect to the longitudinal center 10 of the blank 5 along these hinge-like folding grooves.
- So-called reversing belts 9, which are essentially parallel to the central conveyor belt 2, are used for this purpose. These are endless, circumferential flat belts that rise over the entire conveyor path from a level below the central conveyor belt 2 to a level above the central conveyor belt 2, converge slightly towards the central conveyor belt 2 and, at the same time, converge with their belt side facing upwards at the beginning at the end of the conveyor downwards, ie point towards the central conveyor belt 2.
- a side part 8 lies against each of these belt outer sides. The side part 8 must follow the entanglement of the turning belt and is thereby lifted out of the initially spread position, increasingly pivoted inward along the fold grooves to the longitudinal center of the blank and finally folded from above with the opposite side part 8 and connected to it.
- an initially unwound container blank becomes an annularly closed folding container with at least two fold grooves parallel to one another.
- the fold grooves 7 have a certain transverse extent, according to. Fig. 9 also called fold groove ready B.
- This transverse extent can be in the range of 1 cm, for example. However, this means that the actual folding zone can lie anywhere within the folding groove 7.
- a folding device is arranged in the front region 11 of the entire conveying path.
- This folding device 12 consists of a folding edge 13 lying above the blank 5 and a support zone 14 below the blank corresponding to the folding edge.
- the folding edge 13 arranged above the blank lies linearly on the blank 6 in the longitudinal direction of the folding groove 7.
- the line lies within the predetermined width of the fold groove 7.
- a limiting edge is consequently provided according to the embodiment in FIG. 1, on which the side part 8 is pivoted inwards with millimeter precision, while it is simultaneously conveyed forward by the central conveyor belt 2.
- the blank 6 is pressed against the corresponding contact zone 14 by the linear folding edge 7 with a predetermined force.
- the blank 5 is consequently clamped linearly on both sides of the central part 6 by the folding device 12 provided there at a predetermined position within the fold grooves 7.
- the spacing of the clamping zones is fixed by the arrangement of the folding devices 12 on the machine frame, so that identical internal dimensions can be expected for the entire lot of the folding containers produced on this folding machine.
- the folding device 12 is driven synchronously with the conveying speed 3.
- a drive 15 for the folding device 12 is used for this purpose.
- the drive 15 here consists of the central machine motor 16. This machine motor usually drives all units of one such a machine. These drive means are not shown for reasons of clarity. However, it is important that all drive trains are coupled so that they are slip-free via mechanical connections in order to achieve a synchronous movement of all parts.
- the motor 16 drives the sprockets 18, 19 of the same diameter in each case via a common chain 17, one of which (18) drives the folding edge 13 and the other one (19) Drive of the corresponding support zone 14 is used.
- the rotary movement of the drive 15 is transmitted to the opposite folding device 12 via a continuous drive axis 20.
- the movement of the corresponding support zone 14 is also synchronously coupled to the movement of the folding edge 13 on this side via an additional connecting chain 17.
- Figure 2 shows that the folded edge is formed by a continuously rotating chain.
- the chain strand forming the folded edge 13 is acted upon by a chain pressing device 21 from the opposite side of the strand.
- This chain pressing device 21 has sliding pieces 22 which lie along the folding edge 13 and which are seated on associated holders 23.
- a plurality of such holders 23 with sliders 22 is arranged on a common carrier 24.
- a pressure zone lying along the chain line is hereby realized in order to press the folded edge 13 into the fold groove 7 with a predetermined force.
- Each carrier 24 can be adjusted transversely to the conveying direction 3 by means of a holder 26 in the sense of a change in distance from the respective opposite carrier 24.
- the folding device 12 is thus adapted to different blank dimensions, it being particularly important to ensure that the position of the folded edges 13 is parallel to one another and, if possible, in a common plane.
- the common plane lies parallel to the plane of the blank 5.
- the folding edges be placed exactly in the longitudinal centers 28 of the folding grooves 7.
- the lowest section modulus should be expected there when the side flaps pivot.
- the corresponding support zones 14 have a certain width 27, so that an edge strip still remains on both sides of the folded edges 13. As a result, it is sufficient to leave the position of the corresponding support zone 14, namely the support belt, unchanged when the distance between the supports 24 changes. For this development of the invention, the entire width 27 of the flat belt comes into consideration as the corresponding support zone 14.
- FIG. 3 further shows that the folded edge can be formed by one of the belt edges of a circumferential folding belt 30.
- It is a flat belt.
- the axis 44 of the belt deflection roller 45 is slightly inclined with respect to the normal plane to the plane of the blank 5.
- It is preferably a so-called tracking toothed belt which can absorb lateral forces to a certain extent without shifting from its running plane.
- the belt track provided on such belts engages in a manner known per se in corresponding annular groove-shaped recesses in the deflection rollers 45. In this way, one can achieve a certain contact pressure between the folding belt edge 30 and the groove 7.
- FIGS. 4 and 5 show a further development in which guide devices 32 are provided between the end-side Ural rollers 46, 47 of the belt section forming the support zone on the underside 48, with which said belt section is pressed against the underside of the blank 5.
- the guide device consists of a guide rail 33 which is supported on elastic brackets 34.
- These elastic mounts consist on the one hand of a stationary receptacle 35 and of a rail counterpart 36 which can be moved longitudinally displaceably in this receptacle.
- the counterpart is elastically mounted in relation to the stationary receptacle with spring 37 and presses with a predetermined force against the underside of the belt zone forming the support zone 14 while at the same time the folded edge 13 is held in the opposite direction. In this way, a predetermined pressing force is created along the groove 7 and constant over the length of the front region of the conveying path.
- FIGS. 6 and 7 show that the folded edges 13 are formed by cross plates of an endless chain 39 rotating at the conveying speed.
- This endless chain 39 lies in a recess corresponding to the outer chain contour of a chain guide rail 40 in each case.
- This chain guide rail 40 is a commercially available component and sits on a common carrier 49, which in turn is fastened to the machine frame.
- a chain wheel 50 is arranged at each end of the chain guide rails 14, one of which is rotated via the motor 16.
- the chain guide rail extends along the front area of the conveyor path.
- the recess in the chain guide rail is closely matched to the outer contour of the chain links. Consequently, the cross brackets 41 exactly follow the linear course of the recesses along the front region of the conveyor path. In this way, an essentially constant contact pressure between the folded edge 13 and the fold groove 7 or the corresponding contact zone 14 can be achieved.
- the guide device / chain guide rail can be acted upon by hydraulic cylinders. This offers the advantage of a contact force between the folded edge and the corresponding support zone that is independent of the caliber thickness or carton quality.
- the axes 51 of the chain wheels are arranged essentially parallel to the plane 42 of the blank 5.
- the axes 51 can be slightly inclined to the longitudinal center 10 of the blank 5 in order to avoid an early collision with the inwardly pivoted side parts 8.
- the axes are also arranged perpendicular to the conveying direction 3 in order to avoid relative movements between the cross plates 41 and the blank 5.
- the transverse link plates 41 point radially outwards, based on the axis 51.
- Figure 8 shows that the folding device according to the invention is also suitable as a separate station 55 for the production of fold grooves. Such use should be expressly included.
- a feed station 52 possibly an inking station 53, and a slitting station 54 are arranged one behind the other in the running direction 3.
- a creasing station 55 can now be provided, by means of which the incoming flat blanks are creased in the conveying direction. Bending devices such as those described above are used for this purpose. In this case, however, the side parts are not pivoted inward, so that the pre-grooved flat blanks are required to form a stack 56.
- Embodiments are particularly considered in which the support zone 14 forms a longitudinal groove 58 which is flanked by one or two raised longitudinal regions 59.
- the folded edge forms, with a longitudinal web 60, the counterpart to the longitudinal groove, which essentially lies opposite the longitudinal groove 58 (see FIG. 9).
- the longitudinal web 60 can be pressed into the longitudinal groove 58 with a precise fit, so that the blank is clamped in a line and at the same time is at least temporarily statically grooved.
- the distance between the folded edge 13 and the corresponding support zone 14 is less than the thickness D of the material blank.
- the width B of the fold groove cannot be precisely set.
- the width B essentially comprises the constricted area.
- a downstream folding station 57 as described above, can also be provided.
- FIGS. 10a to c show a development of the invention which is suitable for folding the side parts 8 of the blanks 6 inwards in such a way that a cuboid-shaped folding carton is produced in practice.
- the section of a conveyor belt 2 that is moving in the direction of travel 3 is initially shown.
- the middle part 6 of the blank rests on the conveyor belt 2 and is carried along on a rear edge by the driver 4 in the conveying direction.
- the fold grooves 7 have already been introduced with the folding device. However, the folding device can also lie in the fold grooves 7. Because of the continuously moving central conveyor belt 2, the existing folding grooves 7 therefore sweep a so-called travel area along the conveyor path, which forms a geometric travel line. The central part 6 is moved within these driving lines, the side parts 8 now having to be folded in.
- the reversing belts 9 are used for this purpose, of which the longitudinal section is shown that is currently interacting with the side parts 8.
- the turning belts 9 rise with respect to the linear travel areas of the folding grooves 7 from below to above and converge from outside to inside, as is also shown in FIG. 1.
- the turn belts are therefore in principle not exactly parallel to the side parts 8.
- the belt outer sides 62 run in each case convergent to the pre-emphasized in the drawing derkanten of the side parts 8 and lie there.
- there are front contact points 61 which, according to FIG. 10a, can lie on the belt edge 64 facing the folding groove 7, can extend over the entire belt width according to Figure 10b or are arranged according to 10c in the region of the belt edge 63 facing away from the folding groove 7 are.
- FIGS. 10 a - c therefore essentially consists in showing the different possible contact points 61 between the outside of the belt 62 and the front region of the side parts, which is emphasized here in the drawing.
- the rear regions of the side parts 8 therefore have a predetermined geometric position relative to the outer sides of the reversing belts 9. In any case, this must be assumed that in the rear area of the side parts 8 between the belt outside 62 and the outside of the side part 8, direct contact is initially ruled out.
- One of the belt edges, here 64, is closer to the outside of the side flap 8 than the other of the belt edges (here 63).
- an elevation 65 must be provided on one of the two belt edges 63, 64.
- this increase should lie on the further spaced belt edge 63 in order to obtain a favorable spacing for pivoting the side flap 8 with respect to the fold groove 7 forming the hinge axis.
- the elevation 65 rises so far above the belt outside 62 that the scit part 8 is also guided there with its rear region.
- a rear contact point 66 which preferably engages with a larger lever arm with respect to the folding groove 7 on the side part 8.
- the side part 8 should also abut the rear contact point 66, it must also be ensured that the inward-pivoting side edge 67 is held practically exactly parallel to the folding groove 7 while the blank is driven in the conveying direction and while the side part 8 is doing so is pivoted inwards.
- front contact point 61 and the rear contact point 66 can in principle only rest against the side part in a punctiform manner in order to prevent the point of attack between the reversing belt and side part from moving sideways during the inward pivoting movement.
- the front contact point 61 and the rear contact point 66 by means of a common envelope 68, which should also lie linearly on the side part 8.
- This can be achieved, for example, by arranging continuously decreasing elevations 65 along the envelope 68 starting from the rear contact point 66 to the front contact point 61, the contact points of which with the side parts 8 in each case on the envelope 68 should lie.
- only punctiform contact should be preferred, so that ideally the envelope 68 is only a line.
- the envelope 68 should particularly preferably run diagonally from the rear contact point 66 via the turning belt 9 to the front contact point 61. However, this is not a requirement. It is essential to measure the height of the elevation 65 so that the side edge 67 of the side part 8 is exactly parallel to the fold groove 7 when the side part 8 is supported on the elevation 66.
- the envelope 68 can also be longer than the side part 8. In this way, such a reversing belt 9 is indispensable for processing different folding cardboard dimensions.
