Definitions

  • the present invention concerns a foil wrapping device for cylindrical objects as indicated by the preamble of claim 1, for example cylindrical bales or cylinders of consolidated material.
  • Conventional plastic foil bale wrapping devices have a supportive surface underneath the bale, often referred to as a wrapping table, and means of achieving relative rotation between the bale and at least one film roll.
  • the relative rotation could either be due to a stationary bale, and a moving film roll, or vice versa. This movement must not be confused with the rotation the bale has around its own axis as will be explained in the figure discussion for figure 1.
  • the present invention will be applicable to both these scenarios, and a combination of those.
  • a device for stretching the film is often equipped on the film rolls in order to apply the film tightly without wrinkles, and with increased structural hold of the bale.
  • the bale might be wrapped previously in either a net or a wider plastic film that covers the entire curved surface. The net or this wide plastic film is applied while the bale is in the chamber. It is still necessary to wrap the film further in order to seal the ends of the bale, as well as increasing the thickness at the curved surface. This secondary wrapping process is the one described in this device.
  • the centre of the sides of the bale is provided with approximately 27 layers of foil with this known arrangement, depending on the bale size (this is for bales with diameter 1150mm and width 1200mm) and standard width of the plastic film of 750mm.
  • a foil wrapping device for wrapping foil (14) around a cylindrical object (15) of a predetermined length and diameter, comprising: at least one wrapping arm (12) arranged to hold rolls (13) of foil (14) and a wrapping table comprising a plurality of support rollers (Rl, R2, R3) with parallel length axes, wherein at least one of the support rollers is a powered roller; said wrapping table being arranged to support and rotate the cylindrical object (15) with the predetermined length and diameter placed upon the wrapping table when the axis (Bel) of the cylindrical object (15) is parallel with the length axes of the support rollers; said cylindrical object (15) being defined by a peripheral surface and two circular surfaces, having an axis (Bel) between the centres of the two circular surfaces and a centre point (Bep) on said axis at equal distance from each of said circular surfaces; the at least one wrapping arm (12) being arranged to stretch foil (14) across the cylindrical object (15) and to wrap it in layers of foil partly overlapping
  • a foil wrapping device for wrapping foil (14) around a cylindrical object (15) of a predetermined length and diameter, comprising: at least one wrapping arms (12) arranged to hold rolls (13) of foil (14) and a wrapping table comprising a plurality of support rollers (Rl, R2, R3) with parallel length axes, wherein at least one of the support rollers is a powered roller; said wrapping table being arranged to support and rotate the cylindrical object (15) with the predetermined length and diameter placed upon the wrapping table when the axis (Bel) of the cylindrical object (15) is parallel with the length axes of the support rollers; said cylindrical object (15) being defined by a peripheral surface and two circular surfaces, having an axis (Bel) between the centres of the two circular surfaces and a centre point (Bep) on said axis at equal distance from each of said circular surfaces; the at least one wrapping arm (12) being arranged to stretch foil (14) across the cylindrical object (15) and to wrap it in layers of foil partly overlapping
  • Re(N) is the extension of the support roller (N) in question as a percentage of the length of the cylindrical object (15),
  • JN is the angular position of the support roller R(N) in degrees from a vertical line through the centre of the cylindrical object (15).
  • a method of wrapping foil around a cylindrical object comprising: supporting the cylindrical object on a wrapping table comprising a plurality of support rollers (Rl, R2, R3) with parallel length axes, wherein at least one of the support rollers is a powered roller; rotating the cylindrical object (15) on the wrapping table with an axis (B c i) of the cylindrical object (15) is parallel with the length axes of the support rollers; holding a roll of foil on at least one wrapping arm, and rotating the at least one wrapping arm (12) or the wrapping table to stretch foil (14) across the cylindrical object (15) and to wrap it in layers of foil partly overlapping one another; characterized in that: the wrapping arms (12) are arranged such that a centre line (F c i) of the foil (14) being stretched to the cylindrical object (15) is at an angle 0 in the region between 15 and 45 degrees with the length axes of the support rollers (Rl, R2, R3); and a centre line (F c i) of the foil (14) being stretched to the cylindrical object
  • a method of wrapping foil around a cylindrical object comprising: supporting the cylindrical object on a wrapping table comprising a plurality of support rollers (Rl, R2, R3) with parallel length axes, wherein at least one of the support rollers is a powered roller; rotating the cylindrical object (15) on the wrapping table with an axis (B c i) of the cylindrical object (15) is parallel with the length axes of the support rollers; holding a roll of foil on at least one wrapping arm, and rotating the at least one wrapping arm (12) or the wrapping table to stretch foil (14) across the cylindrical object (15) and to wrap it in layers of foil partly overlapping one another; characterized in that: the at least one wrapping arm (12) is arranged such that a centre line (F c i) of the foil (14) being stretched to the cylindrical object (15) is at an angle 0 in a range between 15 and 45 degrees with the length axes of the support rollers (Rl, R2, R3) and the support rollers

  • 4JN is the angular position of the support roller R(N) in degrees from a vertical line through the centre of the cylindrical object (15).
  • Preferred and optional features of the third and fourth aspects of the invention correspond to preferred and optional features of the first and second aspects of the invention and vice versa.
  • the reference is to any imaginary object of a length and diameter for which the device is designed, since the cylindrical object in question - as such - is not part of the present invention.
  • the various features of the device are hardly possible to describe without including their intended interaction with an (imaginary) object positioned in the device. Thus, it should not be interpreted in any part of the definition of the wrapping device that a cylindrical object actually needs to be present for the definition to be valid.
  • the device according to an aspect of the present invention is arranged to apply film with an inclination angle 0 between the foil applied and the wrapping table.
  • the angle 0 of inclination is typically between 15 and 45 degrees, more preferred between 20 and 35 degrees but may depart from these limits within the scope of alternative aspects of the present invention.
  • the inventive arrangement provides a convenient distribution of film due to decreased clustering in the centre of the sides of the bale compared to conventional wrapping methods and apparatuses.
  • the present invention will rather apply more film towards the periphery of the circular end surfaces, thus reducing the centre clustering, which results in a lower total foil consumption for a given minimum number of applied film layers.

  • a foil wrapping device (10) for wrapping foil (14) around a cylindrical object (15) of a predetermined length and diameter comprising wrapping arms (12) arranged to hold rolls (13) of foil (14) and a wrapping table comprising pairs of powered support rollers (Rl, R2, R3) with parallel length axes, said wrapping table being arranged to support and rotate the cylindrical object (15) with the predetermined length and diameter placed upon the wrapping table when the axis (B c i) of the cylindrical object (15) is parallel with the length axes of the support rollers, said cylindrical object (15) being defined by a peripheral surface and two circular surfaces, having an axis (B c i) between the centres of the two circular surfaces and a centre point (B cp ) on said axis at equal distance from each of said circular surfaces, the wrapping arms (12) being arranged to stretch foil (14) across the cylindrical object (15) and to wrap it in layers of foil partly overlapping one another by rotating one of the wrapping arms (12) and the wrapping table
  • R e (N) is the extension of the support roller (N) in question as a per centage of the length of the cylindrical object (15),
  • 4JN is the angular position of the support roller R(N) in degrees from a vertical line through the centre of the cylindrical object (15).
  • the device is arranged to apply the film with its centre line close to the centre point of any object being wrapped, deviating less than 10% of the diameter of the object, preferably less than 5% of the diameter of the object.
  • using the foil wrapping device according to the present invention reduces the consumption of a standard 750 mm (plastic) foil by at least 50 % compared to the consumption of today's commercial foil wrappers.
  • the amount of wide film used remains unchanged (wide film being the plastic film applied to the bales curved (peripheral) surface inside the harvesting chamber, constituting about 25% of the total amount of film.
  • This means the total foil reduction is about 40%, which is a considerable improvement in bale wrapping, with a significant positive environmental effect.
  • the number of necessary rotations of the wrapping arms is reduced correspondingly, thereby improving the wrapping capacity vastly, as well as reducing the required energy consumption.
  • Figure 1 is a schematic, simplified, transparent side view of an embodiment of a wrapping device according to the present invention
  • Figure 2 is a schematic, simplified transparent side view of an embodiment of a wrapping device according to the present invention in a slightly different orientation;
  • FIG. 3 is a schematic, simplified front view of some details of the wrapping device according to the present invention.
  • Figure 4 is an enlarged side sectional view of some of the elements of Figure 1.
  • bale a cylindrical object to be wrapped is for convenience referred to as a bale.
  • FIG. 1 is a simplified, transparent side view of the central parts of a wrapping device 10 according to the present invention, comprising a chassis (11), wrapping arms 12 holding foil rolls 13 of plastic foil 14 being wrapped around a bale 15 resting on a wrapping table mainly consisting of three pairs of support rollers, Rl, R2, R3. Only one roller of each pair is visible in the drawing, the other ones being hidden behind the ones shown and behind the bale 15.
  • the support rollers will be rotatably arranged in order to be able to rotate the bale during packing. This is not to be confused with a rotation of the entire wrapping table around an imaginary axis perpendicular to the axes of the support rollers, which is a non-mandatory feature of the present device, not described in further detail herein.
  • the bale is shown slightly tilted one way (to the right in the drawing) in relation to the support frame 11 while the wrapping arms 12 are tilted the other way, resulting in an angle 0 between the centre line Bci of the bale and the centre line F ci of the foil being wrapped thereon.
  • Figure 1 shows an ideal configuration of the device in the sense that the foil centre line F ci of passes through the bale centre point B C p, i.e. through the exact centre of the bale. Adjustments of the table position, the wrapping arms' position and their respective degree of tilt will affect this configuration.
  • the angle 0 shown in Figure 1 is about 25 degrees.
  • the centre line B ci is also designated the axis of the bale - or more generally -of a cylindrical object to be wrapped.
  • the angle 0 may also be defined as the angle between the foil centre line and the length axes of the support rollers. This is in fact a more fundamental definition since the cylindrical object is not as such part of the present invention.
  • the support roller pair Rl close to the lowermost part of the bale, has an extension only slightly less than the bale length, leaving about 10% of the bale length unsupported.
  • the second support roller pair R2 is significantly shorter, leaving about 25% of the bale length unsupported while the third support roller pair R3 is even shorter, leaving about 45% of the bale length unsupported.
  • This arrangement of gradually shorter support rollers when moving from the lowermost part of the bale up to higher parts is of significance for allowing the desired manner of bale wrapping, using an angle 0 between the foil centre line F ci and the bale centre line B c i.
  • the angle 0 is preferably in the region 20 to 35 degrees.
  • the reduced extension of the support rollers is required to avoid conflict thereof with the foil to be wrapped.
  • angle 0 is the parameter of interest for the wrapping geometry of the present invention, its contribution from tilting of the wrapping table is primarily for the sake of ensuring that the partly unsupported bale or another cylindrical object does not slide off the wrapping table.
  • the wrapping table may have a permanently tilted orientation, or it may be arranged to shift between a more horizontal orientation and the shown tilted orientation e.g. by hydraulic means.
  • FIG. 1 The broken line III - III in Figure 1 shows the section line at which Figure 3 is based.
  • Figure 2 shows principally the same as Figure 1, but in this case the bale is positioned somewhat lower, causing the centre line F ci of the foil to pass at a distance d above the bale centre point B cp .
  • a slight deviation from crossing of the foil centre line F ci through the bale centre point B ci is acceptable within the scope of the invention but the offset or deviation d should not exceed 10 % of the bale diameter and more preferred not more than 5% of the bale diameter.
  • FIG 3 is a schematic, simplified front sectional view of a bale 14 supported by three pairs of support rollers Rl, R2, R3 as in Figures 1 and 2.
  • the support rollers are all parallel to the bale centre line Bci which in Figure 3 is perpendicular to the paper plane.
  • the longer support rollers Rl are rather close to a vertical line, B vi from the centre of the bale, at an angle cfi typically in the range 10 to 20 degrees from the vertical line B V
  • the somewhat shorter support rollers R2 are positioned at an angle cfz typically in the range 20 to 30 degrees from same vertical line.
  • the shortest support rollers R3 are typically positioned at an angle cfa in the range 30 - 45 degrees from the same vertical line.
  • the support rollers are arranged in a manner defining part of an imaginary circle with a radius corresponding to the radius of the objects to be received and wrapped.
  • This imaginary circle may be referred to independent of whether or not a cylindrical object is present on the support rollers of the wrapping table.
  • the reference may as well be replaced by replaced by "a vertical line through the imaginary circle defined by the support rollers”. This denotation is more fundamental in the sense that it does not depend on a cylindrical object actually being present on the wrapping table.
  • Figure 4 is a side view of a few elements of the device, the support rollers, shown in the same way as in the more comprehensive drawings of Figure 1 and 2.
  • Figure 4 in consideration of Figure 3, illustrates the correlation between the positions and the longitudinal extensions of the support rollers Rl, R2, and R3.
  • the lowermost pair of support rollers, Rl typically positioned at an angle in the range 10 to 20 degrees from the vertical line B v i, has a relative longitudinal extension R e (l) of about 90% of the bale length.
  • the second pair of support rollers, R2 typically positioned at an angle in the range 20 to 30 degrees from same vertical line has a relative longitudinal extension R e (2) of about 75% of the bale length

  • R e (N) ⁇ 105 - 1.4 x 35 56; i.e. R e (N) ⁇ 56 % of the length of the cylindrical object.
  • the length extensions of the support rolls in practice are chosen within 80 to
  • the functionality of the device depends also on the width of the foil to be applied.
  • a narrow foil will require an excessive number of turns for wrapping the cylindrical object properly while an excessive width would come in conflict with the support rollers of the wrapping table. While fine-tuning of width in relation to a certain geometry (length and position of support rollers in combination with a specific angle 0) is possible, a sound choice covering a multitude of combinations may easily be found by a person skilled in the art.
