Foil wrappping device

The present invention concerns a foil wrapping device for cylindrical objects as indicated by the preamble of claim 1.

Background

5 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 10 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 15 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.

During wrapping the bale is slowly turned around its own axis on the wrapping table at a speed adapted to the rotational velocity film roll, to ensure a certain overlap of the foil from one turn to the next. Due to the geometry of the present wrapping method, where every layer of film will wrap 20 the centre of the bales side surfaces, but only a small portion of the edges of said side surfaces, much more plastic film foil will be applied in the centre of the sides than on the edges. In order to obtain a foil wrapped bale with at least 6 layers of foil at every point of the bale, 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 25 standard width of the plastic film of 750mm. This means that an excessive amount of plastic foil, and number of rotations of the film roll, is necessary to achieve a certain coverage, which is very unsuitable for the environment in terms of plastic consumption, but also for the efficiency of the wrapping process. The number of layers is essential for the preservation of the bales’ material, where more layers gives a better preservation. If the bale is covered as the example above, with 27 30 layers in the central cluster, and 6 at the edges, the edges will be the point of leakage and thus the limiting factor for the quality of the bales’ preservation.

350009

WO 2015/185732 describes a bale wrapping device comprising a mechanism for adjusting a roller between fixed positions to facilitate centred wrapping of different bale sizes, and comprising tilting of wrapping table rollers between 3 degrees to 10 degrees to prevent drift of a bale off the end of the rollers and compensate for the tendency of fast rotation of the bale to cause offset wrapping.

5 GB 2269795 describes a bale wrapping device comprising a rotary table that has length and width that is smaller than the dimensions of the bale so that the bale will project beyond the table at all sides.

Objectives

It is an objective of the present invention to provide a foil wrapping device suitable for use on 10 cylindrical objects, such as bales of fodder and the like. It is a specific objective that the device is effective with regard to the amount of foil consumed in the process and with regard to the time and energy spent for the process.

The present invention

The above indicated objective is achieved by the foil wrapping device according to the present 15 invention, as defined by claim 1. Claim 4 defines a particular aspect of the present invention.

Preferred embodiments of the invention are disclosed by the dependent claims.

It should be noted that, with regard to claim definition, wherever there is a mention of a (or the) cylindrical object to be wrapped, 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 20 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 the present invention is arranged to appliy film with an inclination angle θ 25 between the foil applied and the wrapping table. The angle θ 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 the present invention. The inventive arrangement provides a convenient distribution of film due to decreased clustering in the centre of the bale’s sides compared to regular wrapping methods and apparatuses. The present invention will rather apply more film towards the 350009

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.

It is a further criterion that 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, 5 preferably less than 5% of the diameter of the object.

According to full scale test results in the form of a bale wrapper, 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 10 (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.

15 Below the invention is described in further detail in the form of non-limiting embodiments illustrated by the enclosed drawings, where:

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 20 according to the present invention in a slightly different orientation;

Figure 3 is a schematic, simplified front view of some details of the wrapping device according to the present invention; and

Figure 4 is an enlarged side sectional view of some of the elements of Figure 1

By schematic is understood that the components are not necessarily shown with mutually correct 25 dimensions and by simplified is understood that certain components that may or will be present in a real life operational device, such as power supply, control systems, electric components, hydraulic components etc., which as such do not constitute inventive elements, are omitted.

In the following, a cylindrical object to be wrapped is for convenience referred to as a bale.

Figure 1 is a simplified, transparent side view of the central parts of a wrapping device 10 according 30 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 350009

of support rollers, R1, 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 5 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 θ between the centre line Bcl of the bale and the centre line Fcl of the foil being wrapped thereon. Figure 1 shows 10 an ideal configuration of the device in the sense that the foil centre line Fcl of passes through the bale centre point Bcp, 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 θ shown in Figure 1 is about 25 degrees. The centre line Bcl is also designated the axis of the bale - or more generally – of a cylindrical object to be wrapped. Since the centre line of a cylindrical 15 object properly arranged on the wrapping table will be parallel with the length axes of the support rollers, the angle θ 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.

It is worth noticing that the support roller pair R1, close to the lowermost part of the bale, has an 20 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 25 bale wrapping, using an angle θ between the foil centre line Fcl and the bale centre line Bcl. As mentioned, the angle θ 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.

While the angle θ 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 30 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.

The broken line III – III in Figure 1 shows the section line at which Figure 3 is based.

350009

Figure 2 shows principally the same as Figure 1, but in this case the bale is positioned somewhat lower, causing the centre line Fcl of the foil to pass at a distance d above the bale centre point Bcp. A slight deviation from crossing of the foil centre line Fcl through the bale centre point Bcl is acceptable within the scope of the invention but the offset or deviation d should not exceed 10 % 5 of the bale diameter and more preferred not more than 5% of the bale diameter.

Figure 3 is a schematic, simplified front sectional view of a bale 14 supported by three pairs of support rollers R1, R2, R3 as in Figures 1 and 2. The support rollers are all parallel to the bale centre line Bcl which in Figure 3 is perpendicular to the paper plane. The longer support rollers R1 are rather close to a vertical line, Bvl from the centre of the bale, at an angle φ1 typically in the range10 to 20 10 degrees from the vertical line Bvl. The somewhat shorter support rollers R2 are positioned at an angle φ2 typically in the range 20 to 30 degrees from same vertical line. Finally, the shortest support rollers R3 are typically positioned at an angle φ3 in the range 30 – 45 degrees from the same vertical line.

It is not essential that there are three pairs of support rollers as illustrated, it may be just two pairs 15 or it may be even more than three pairs. More than three pairs are however usually not required and would make the overall design unnecessary complicated. Use of three pairs normally ensures sufficient support vertically and horizontally.

It should be noted, with reference still to Figure 3, that 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 20 received and wrapped. This imaginary circle may be referred to independent on whether or not a cylindrical object is present on the support rollers of the wrapping table. Thus, when referring to “a vertical line through the centre of the cylindrical object”, 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 25 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 R1, R2, and R3. The lowermost pair of support rollers, R1, typically positioned at an angle in 30 the range10 to 20 degrees from the vertical line Bvl, has a relative longitudinal extension Re(1) 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 Re(2) of about 75% of the bale length, while the third pair of support rollers R3, typically positioned at an 350009

angle φ3 in the range 30 – 45 degrees from the same vertical line has a relative longitudinal extension Re(3) of just about 55% of the bale length.

Thus, when considering Figures 3 and 4 combined, it is seen that there is an inverse correlation between the angle φ (in degrees) and the relative supported length extension Re(N) of the bale, N 5 being an integer 1, 2 or 3 indicating which pair of support rollers the Re(N) refers to. The larger the angle φ, the shorter the support roller.

This may be expressed mathematically in an equation constituting a mandatory feature of one specific aspect of the present invention, namely

Re(N) < Nemp - k φN

10 where

Re(N) is the extension of the support roller in question as a per centage of the length of the cylindrical object,

k is a constant decided empirically

φN is the angular position of the support roller in degrees from a vertical line through the 15 centre of the cylindrical object (or a vertical line through the imaginary circle defined by the support rollers),

Nemp is an empiric number found in the development of the present invention.

It has been found that Nemp is 105 and that k =1,4.

Thus, for a given pair of support rollers positioned at a given angle φ from the vertical line through 20 the centre of the cylindrical object, the maximum relative extension Re of a support roller can be calculated.

As an example, for a roller (pair) arranged at φN = 35 degrees, the maximum relative length extension, Re(N) max (as per centage of the length of the cylindrical object) for the support roller is calculated as:

25 Re(N) < 105 – 1.4 x 35 = 56; i.e. Re(N) < 56 % of the length of the cylindrical object.

It is preferred that the length extensions of the support rolls in practice are chosen within 80 to 100% of the calculated value for Re(N) and more preferred in the region 90 to 95% thereof.

To some extent, 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 350009

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 θ) is possible, a sound choice covering a multitude of combinations may easily be found by a person skilled in the art. The foil width illustrated in Figure 5 1, constituting 58 % of the diameter of the cylindrical object, is within such general functional area useful for most geometries of the device.
