Definitions

  • the present invention relates to a packaging machine for packaging objects in a film, with a tube forming device for forming a tube from a film which is essentially flat before tube forming, and a transport device for transporting the objects into the tube, the tube forming device having a plurality of pairs of shaped edges for deflection the film has.
  • a packaging machine of the type mentioned is known from DE 40 21 934 A1.
  • the tube forming device has a plurality of guide plates, which essentially have three pairs of shaped edges, around which the film is guided one after the other.
  • a first wing-like guide plate feeds the packaging film obliquely downward against the transport direction of the objects to be packaged, the film being deflected by means of the first guide plate and two further guide plates arranged in scissors and formed into a tube which runs in the transport direction of the objects to be packaged.
  • the individual shaped edges of the guide plates are arranged relative to one another in such a way that the film is independent of the form edge or the area of the guide plates it runs, is evenly tensioned and even, ie runs over the edges without torsion. Form edges overlapped by the film lie in pairs in a common plane.
  • the present invention is therefore based on the object of specifying a packaging machine with an improved tube forming device of the type mentioned at the outset.
  • excessive stress on the film should be avoided and overstretching of the film should be prevented.
  • the film is guided over the mold edges in such a way that the edges of the film run tension-free or loosely over the mold edges. This has the advantage that the film is protected at the edges from excessive tension and overstretching.
  • the film runs wrinkle-free over the tube forming device despite the non-constant tension distribution. So far it has always been assumed that the path over the mold edges parallel to the edges of the film must be of the same length for all areas of the film in order to prevent that the film converges towards its central area and accordingly folds. However, the opposite is the case.
  • the foil that is guided or drawn over the edges of the mold tries to run over the edges of the mold in the shortest possible way and is tightened very slightly across the longitudinal direction of the foil towards the edges, so that no folds occur.
  • the film or parts thereof run successively over first mold edges of a first mold shoulder and second and third mold edges of a second mold shoulder.
  • first mold edges and an associated one, i.e. second mold edge overrun by the same piece of film, not in one plane.
  • shape edges of the same pair of shape edges can lie in a common plane.
  • Edges overlapped one after the other by the film are thus skewed to one another. So far it has been assumed that the edges of the film which have been overrun one after the other must lie in one plane in order to guide the film without folds and evenly stretched over the edges of the tube forming device.
  • one of the first mold edges and an associated second mold edge are in each case arranged relative to one another in such a way that the film is interlaced between the respectively associated first and second mold edges. This has the advantage that the film is guided gently and loosely over the edges of the mold.
  • the first shape shoulder can be separated from the second shape shoulder, ie it cannot be connected to it, and is expediently arranged above the second shape shoulder.
  • the first shape shoulder is preferably designed as a trapezoidal, in particular multi-piece sheet metal part and the second shape shoulder, which is essentially in the transport plane the transport device, has two substantially triangular pieces of sheet metal, which overlap each other in a scissor-like manner, such that the third mold edges converge and overlap in the hose exit direction and that the second mold edges diverge in the hose exit direction.
  • the shape shoulders can be made of different materials, but the shape shoulders in sheet metal construction have advantages in terms of a simple and stable design.
  • the shaped shoulders can also be designed in a frame-like manner in such a way that only the shaped edges are provided in the manner of ribs, but the plate-shaped sheet metal construction has advantages with regard to a uniform and smoothly sliding film guide.
  • the angular orientation of at least one of the pairs of mold edges, in particular the first mold edges is adjustable.
  • the degree of entanglement of the film running over the form edges and the amount of the distance difference between the areas in which the edge of the film runs and the area in which a central section of the film runs over the form edges can be set.
  • the stress distribution in the film and the belly which the film has on the film edges between successive mold edges can be adjusted.
  • the adjustability of the angular alignment of at least individual shaped edges has the advantage that the geometry of the tube shaping device is based on different foils of different thicknesses and made of different materials can be adjusted.
  • the angular orientation can also be adjusted as a function of the size of the objects to be packaged in order to optimally pull the film over the tube shaping device in the case of different objects which require a different tube geometry and different overlap widths. In particular, it can be adjusted to what extent the edge of the film runs loosely over the mold edges and the tension in the film is distributed differently.
  • the corresponding adjustable mold edges have an adjustment range such that these mold edges do not lie in one plane with the respectively associated mold edges of the next pair of mold edges and that there is always an entanglement of the film guided over the mold edges and the edge regions of the film are guided stress-free and loosely.
  • the shaped edges are expediently pivotable in a common plane.
  • the angle of the mold edges to one another in this plane is therefore adjustable.
  • the first shape shoulder preferably has two sheets which are arranged in a common plane and each have a first shape edge, the sheets being pivotable about an axis perpendicular to the common plane. The sheets can thus be swiveled in the plane that you define yourself.
  • the first mold shoulder can also be pivoted as a whole about a substantially horizontal axis, as a result of which the effective angle of the first mold edges can be adjusted relative to the second mold edges, but the embodiment described above has advantages with regard to simple pivoting mounting of the mold shoulder plates.
  • the first and second mold edges each intersect at one point in their extension, the first mold edges being more widely spread than the second mold edges.
  • the orientation of the mold edges is preferably such that the projection of the angle enclosed between the first mold edges into the plane of the second mold edges is greater than the angle which is limited between the second mold edges.
  • the mold edges can be translationally displaceable, the mold edges preferably being displaceable in pairs in opposite directions and at least one pair of the mold edges being displaceable relative to the other mold edges, in particular in such a way that a height and a width of the tube formed from the film can be adjusted.
  • the objects which are to be packaged are conventionally delivered on the side of the tube forming device which is opposite the side on which the film formed into the tube runs out of the tube forming device and through the tube forming device between the shaping shoulders transported in the draining hose. It is known to feed the transport device or, in the case of a multi-piece design of the transport device, a portion of the same into the hose-forming device in order to be able to transport the corresponding object into the draining hose over the shaped sheets.
  • this known embodiment is structurally relatively complicated and economically unsatisfactory.
  • a packaging machine is provided with an improved transport device, in which in particular the transport device reliably transports objects of different sizes even with different settings of the tube forming device into the tube formed from the film effect. For this purpose, the position of a downstream end of the transport device can be adjusted.
  • No transport device is provided in the area of the tube forming device itself and the objects are transported indirectly through the film itself in the area of the tube forming device.
  • the downstream end of the transport device is adjustable such that the objects to be transported can always be brought directly up to the hose forming device even with different settings of the hose forming device and can be pushed onto the film running in the hose forming device. There is no or only a minimal gap between the end of the transport device and the tube forming device, which gap could hinder the forward movement of the object to be transported.
  • the downstream end of the transport device can preferably be set synchronously with the movable shaping shoulder of the hose shaping device.
  • the adjustable end of the transport device is thus coupled to the movable mold shoulder in such a way that when the mold shoulder is adjusted, for example for different geometries of the objects to be packaged, the transport device is adjusted automatically and in such a way that the end of the transport device ends directly on the mold shoulder and there is no larger gap between the transport device and the form shoulder.
  • an effective transport path of the transport device is adjustable in length. This has the advantage that the upstream end of the transport device can be arranged in a stationary manner, in particular following a feed for the objects, and at the same time the Position of the downstream end of the transport device is adjustable.
  • the downstream end of the transport device is adapted to an opposite contour of the hose shaping device, wherein preferably a front edge of the hose shaping device, over which the objects are pushed into the hose shaping device, is V-shaped and the downstream end of the transport device is tongue-shaped into the V-shaped one Recess of the hose forming device extends.
  • the downstream end of the transport device can be moved back and forth in the transport direction in such a way that the complementary V-shaped end of the transport device moves back when the V-shaped opening of the hose forming device is scissor-like is narrowed to set a smaller width of the tube formed from the film.
  • the transport device has at least one endless conveying means rotating around deflecting means, the conveying means being guided around a displaceable deflecting unit at the downstream end of the conveying device.
  • the displaceable deflection unit via which the conveying means is guided in an S-shape, is arranged between two fixed deflecting means and can be moved back and forth parallel to the straight sections of the conveying means between the deflecting unit and the two fixed deflecting means.
  • the conveyor can be pre-tensioned without a special tensioning device such as tensioning rollers.
  • a length adjustment of the conveying path, ie a displacement of the deflection unit can be effected without changing the length of the path covered by the conveying means.
  • the funding advantageously has one uniform tension that is not affected by inertial effects such as a dancer roller commonly used to tension endless belts.
  • the transport device preferably has a plurality of narrow conveyor belts running in parallel, the conveyor belts preferably being guided at the downstream end of the transport device around rollers which are offset in steps, such that the downstream end is adapted in stages to the V-shaped front side of the tube-forming device.
  • the rollers can be mounted on a common, displaceable carriage and can be displaced synchronously with one another parallel to the conveying direction.
  • a removal device for removing the objects wrapped in the hose connects to an outlet side of the hose forming device essentially flush with the latter.
  • the removal device preferably has a suction belt conveyor, in which the objects wrapped in the hose are sucked onto a conveyor belt.
  • the suction also causes the hose running out of the hose molding device to be transported if no objects are enclosed therein.
  • the suction causes the hose to adhere to the conveyor belt.
  • the discharge device could also provide an electrostatic attraction of the film to the conveyor belt, but the suction of the draining hose has advantages in terms of stable static friction between the film and the conveyor belt, in particular also with different films.
  • an automatically adjustable packaging machine is created, in particular an adjusting device for adjusting the tube shaping device for different objects to be packaged and a control device for controlling the adjusting device as a function of object parameters, e.g. Length, width and height etc. of the object are provided.
  • the object parameters can, for example, be entered manually using a corresponding input unit.
  • the packaging machine preferably has a memory device for storing the object parameters assigned to each object, the control device reading the corresponding object parameters from the memory device by means of a reading unit and controlling the setting device as a function of these stored parameters.
  • an input unit is provided with which the object to be packaged can be input.
  • the control device then reads the object parameters assigned to this object from the storage device in order to control the setting device accordingly.
  • a detection device could also be provided, with the aid of which the object to be packaged is automatically detected. According to the result of the automatic detection, the respective object parameters are then read from the memory in order to control the setting device.
  • An evaluation unit can be connected downstream of the detection device to evaluate which stored object the detected object corresponds to or comes closest to.
  • the adjusting device can have a plurality of servomotors, each of which is assigned to different axes of movement of the tube shaping device and is controlled by the control device.
  • Servomotors are preferably assigned to both the translatory displacement axes and the angular adjustment axes of the tube shaping device.
  • Stepper motors can be used as servomotors, an indirect displacement measurement being provided by counting the step pulses.
  • Servomotors can also be provided, it being possible for direct displacement measurement by means of pulse generators and evaluation in a suitable controller to be provided.
  • the adjusting device is preferably coupled to the transport device.
  • the transport device is therefore also automatically adapted to the object to be packed and the corresponding setting of the tube forming device.
  • Downstream units such as a film sealing device, can also be controlled by the control device.
  • a completely automatic setting of the packaging machine is thus effected by entering or recording the object to be packaged.
  • the control device described can also particularly advantageously simplify the setting up of the tube shaping device for completely new objects to be packaged, in that the known object closest to the new object is first selected.
  • the control device then initially effects a presetting according to the parameters stored for the known object.
  • a fine adjustment can then be made, for example, after a test run.
  • a parameter input unit is preferably provided for this.
  • the packaging machine has a tube-forming device 1, a transport device 2 with which objects 4 to be packaged are transported through the tube-forming device 1 into a tube 6 formed from film 5, and a discharge device 3 which holds the tube 6 emerging from the tube-forming device 1 and the therein arranged objects 4 transported away from the tube forming device 1 (FIG. 1).
  • the tube shaping device 1 has an upper, first shaping shoulder 7 and a lower, second shaping shoulder 8 (FIG. 4), via which the film 5, which is removed from a supply roll 9 via a compensating roll 10, is successively guided to act as a hose 6 emerge from the tube forming device 1.
  • the tube 6 essentially has a rectangular cross-section, the edges 11 of the film 5 overlapping at the bottom of the tube 6.
  • the two shaped shoulders 7 and 8 essentially span two planes which are inclined to one another and intersect approximately in the transport plane defined by the transport device 2.
  • the lower, second form shoulder 8 lies essentially in the conveying plane of the transport device 2, while the upper, first form shoulder 7 increases in the conveying direction 13 in such a way that the film 5, which over the upper form shoulder 7 is pulled, as shown in FIG. 4 from top right to bottom left.
  • the shaping shoulders 7 and 8 have several pairs of shaping edges, over which the film 5 is guided and bent to be formed into the tube 6.
  • the upper mold shoulder 7 has on its outer sides a first pair of mold edges 12, over which the outer edge regions of the film 5 are first guided near the edges 11 thereof before they reach the lower mold shoulder 8.
  • the first mold edges 12 lie in a common plane, namely in the plane of the mold shoulder 7 and converge in the direction of the film 5 drawn over the first mold shoulder 7.
  • the extensions of the mold edges 12 intersect at a convergence angle u (FIG. 5). As shown in Fig.
  • the first mold shoulder 7 has two guide plates 14, each of which has one of the mold edges 12 and is movable, as will be described in more detail later, about the guidance and tension of the film 5 and the geometry of the emerging To be able to adjust the film tube 6.
  • the baffles 14 are metal sheets.
  • the lower, second shaped shoulder 8 also has two guide plates 15 and 16, which, however, do not lie in one plane like the guide plates 14, but are arranged in two parallel planes and overlap one another, with a narrower one between the two guide plates 15 and 16 according to FIG 1 is a horizontal gap through which the film 5 can be guided, as will be explained below.
  • the two guide plates 15 and 16 are substantially triangular and together have a second pair of mold edges 17, which are arranged on the outer sides of the mold shoulder 8, and a third pair of mold edges 18, which overlap one another and define a V-shaped opening at the front of the shape shoulder 8.
  • the second mold edges 17 diverge in the direction of the hose 6 emerging from the hose molding device 1. Extensions of the second mold edges 17 intersect at a convergence angle v.
  • the third shaped edges 18 converge in the direction of the emerging hose 6 and limit an angle w in the projection onto the conveying plane of the transport device 2.
  • the arrangement of the mold edges to one another is such that the path across the various mold edges 12, 17, 18 and 19 along different lines, which are each parallel to the edges 11 of the film 5, measured from an entry of the film 5 into the tube forming device 1 on an entry edge 20 up to the exit of the film 5 on a vertical cross section of the tube 6 on the rear edges 21 of the lower shape shoulder 8 is of different lengths.
  • the above-described path is shorter in regions near the edges 11 of the film 5 than in regions towards the longitudinal center axis of the film 5. As will be described in more detail later, this leads to the edges 11 running loosely and untensioned over the mold edges and, particularly in the region between the first mold edges 12 and the second mold edges 17, forming a belly (FIG. 4).
  • the first molding edge 12 and the second molding edge 17 each overlapped by the film 5, that is, according to FIG. 5, a right one of the first and second molding edges and a left one of the first and second molding edges are not in arranged on a common level, but are skewed towards each other.
  • the film 5 is thereby entangled in the area between the first mold edges 12 and the second mold edges 17.
  • a multiplicity of angle combinations of the angles u, v and w are possible in order to achieve, on the one hand, the absence of tension in the edges 11 and, on the other hand, the entanglement of the film 5 in the region between two associated shape edges 12 and 17 .
  • angles u, v and w can be, for example, 70, 20 and 90 °. If the angle u lying in the plane of the first shape shoulder 7 is projected into the plane of the angle v lying in the conveying plane, the projection of the angle u is always greater than the angle v.
  • the molding edges 12, 17 and 18 are movable around and along different axes.
  • the first shape shoulder 7 is displaceable along an axis a parallel to a connecting straight line of the front edge 19 of the first shape shoulder 7 and a front edge 210 of the second shape shoulder 8 (FIG. 6).
  • a carrier 22, which is connected to the two guide plates 14 of the first shaped shoulder 7, is displaceably mounted on a stand 23 along the axis a and engages via an arm 24 with a spindle 25 for height adjustment of the first shaped shoulder 7. This eliminates the need for a handwheel that moves with the form shoulder.

  • a servomotor not shown, can also be provided for this.
  • the fourth shaped edges 19 are formed by cylindrical rollers 30 which are rotatably mounted on the base support 29.
  • the rollers 30 reduce the stress on the film 5 due to the relatively acute-angled deflection at the mold edge 4 and reduce the friction of the film 5 at this mold edge.
  • the tension of the film 15 can be set in the regions of the edges 11 and the bulge of the film between the first mold edges 12 and the second mold edges 17.
  • the transport device 2 In order to transport the objects 4 into the hose 6 spanned by the two form shoulders 7 and 8, the transport device 2, as shown in FIG. 1, has a plurality of narrow, parallel conveyor belts 31 which place the objects 4 on the lower form shoulder 8 or to slide the film 5 drawn over the lower shape shoulder 8.
  • the conveyor belts 31 are guided around rollers 32, 33, 34 and 35 which are offset in a stepped manner such that the ends of the individual conveyor belts 31 are stepped in a V-shape and the V-shaped one delimited by the third shaped edges 18 Opening of the lower shape shoulder 7 are adjusted.

  • the lower shape shoulder 8 is widened, ie when the two guide plates are pushed apart 15 and 16 transversely to the conveying direction, the downstream end is pushed forward in the conveying direction in order not to allow a gap to arise between the transport device 2 and the lower mold shoulder 8.

  • the deflection rollers 32 to 35 and 41 mounted on the slide 36 can be rotated between two fixed ones mounted deflection rollers 42 and 43, around which each of the conveyor belts 31 is guided.
  • the section of the conveyor belts 31 between the deflection roller 43 and the deflection rollers 32 to 35 and the section of the conveyor belts 31 between the deflection roller 41 and the deflection roller 42 run in mutually parallel planes.
  • the displaceable deflection unit with the deflection rollers 32 to 35 and 41 can be moved back and forth parallel to these planes in the conveying direction in order to adjust the position of the downstream conveying end of the transport device 2, the distance covered by the conveyor belts 31 being constant.
  • the conveyor belts 31 can therefore be subjected to a predetermined and constant tension.
  • a removal device 3 is provided for the removal of the objects 4 on the hose exit side of the hose shaping device 1.
  • the discharge device 3 has a suction conveyor belt 45 perforated with air suction holes 44, which rotates endlessly and whose upper side lies in the plane of the second, lower shape shoulder 8.
  • the upstream end of the conveyor 3 connects flush to a rear edge of the second, lower mold shoulder 8 and takes over the objects 4 pushed into the hose and the film hose 6 itself downstream of the hose shaping device 1.
  • the area of the hose shaping device 1 itself ie in the area of the lower shaping shoulder 8, so no conveyor is provided.
  • the objects 4 are transported in this area indirectly through the film 5, which is pulled over the guide plates 15 and 16 of the second, lower mold shoulder 8.
  • the suction conveyor 3 also acts as a pulling device for the film 5 and can pull the film 5 through the tube forming device 1 even in the absence of objects 4 to be packaged. In particular, the threading of the film 5 into the tube forming device 1 is made easier as a result.
  • the packaging machine shown also has a control device and a storage device, which are not shown in the figures.
  • corresponding object names such as height, width, length and other parameters that influence the setting of the tube shaping device, such as color of the object or type of film, necessary melting temperature, etc.
  • the control device is connected to the servomotors in order to control them as a function of the stored object parameters.
  • the object to be packaged is selected via an input unit (also not shown), after which the parameters stored under the corresponding designation are read from the data memory by the control device.
  • the control device uses this to calculate the target position for the actuators and controls them with corresponding signals.
  • the calculated values are transferred to the engine control system via a bus system.
  • the servomotors move to the desired position and report that the position value has been reached to the controller via the bus system. Accordingly, the tube shaping device is set completely automatically only by entering the object to be packaged.
  • the film 5 is threaded into the tube forming device 1.
  • the film 5 is removed from the supply roll by hand and guided over the guide plates 14 of the upper shape shoulder 7.
  • the edge regions of the film 5 are over the first mold edges 12 of the first, upper mold shoulder 7 drawn and one after the other around the second and third mold edges of the guide plates 15 and 16.
  • the section of the film 5 guided under the guide plate 15 and the edge of the film 5 folded over on the upper side of the guide plate 16 are pulled through the gap between the two guide plates 15 and 16.
  • the film 5 is drawn through the tube forming device 1 to such an extent that a sufficient section comes to rest on the discharge conveyor 3.
  • the width and height of the running hose 6 required for the respective objects 4 is set by actuating the adjusting spindle 26 and the height adjusting spindle 46. This can be done before or after threading the film 5 and is effected by the control device and the servomotors, which form a motorized adjusting device, after a corresponding input of the object.
  • the film 5 is pulled through the tube forming device 1.
  • the orientation of the first mold edges 12 can be adjusted by pivoting the guide plates 14.
  • pivoting the guide plates 14 outwards in the direction of the arrows f the distance to be covered by the film in the region of the edges 11 is extended, the belly of the film 5 in the region between the first mold edges 12 and the second mold edges 17 is reduced and, if appropriate, the tension of the Foil 5 increased in the edge areas.
  • Pushing the guide surface 14 against the arrows f reduces the tension in the edge regions 11 and increases the size of the belly which the film 5 throws in the region between the first and second mold edges 12 and 17.
  • This angle setting can also be effected by the control device, readjustment possibly being carried out manually or by manually entering corrected setpoints.
  • the objects 4 are transported from left to right on the transport device 2 and pushed into the film tunnel spanned by the shaped shoulders 7 and 8. In the area of the lower shape shoulder 8, the objects 4 are transported through the film 5 drawn over the lower shape shoulder 8. Downstream of the hose shaping device 1, the objects are transported away by the removal conveyor 3 and, if necessary, fed to a welding device.
