    Field of the Invention The present invention relates to a method for transporting and placing foil rolls on a foil wrapping machine, preferably intended for wrapping agricultural grades, where a number of foil rolls is arranged, preferably with a vertical orientation, on a pallet, and where the foil wrapping machine is pulled by a vehicle, preferably a tractor.
    The invention further relates to a device for transporting and placing foil rolls on a foil wrapping machine preferably intended for wrapping agricultural crops, wherein a number of foil rolls are arranged, preferably with a vertical orientation, on a pallet, and where the foil wrapping machine is pulled by a vehicle, preferably a tractor . Background of the invention Stretch foil or wrap foil is used to a large extent in agriculture not only in Denmark but in most of the world. Wrapped balls are everywhere, the so-called “food packages” are typically wrapped in white or green plastic. In addition, wrapped straw stacks are seen where two or more straw bales are placed on top of and next to each other in up to 5 layers.
    The consumption of wrap foil is very large measured in the number of rolls that must be handled when changing rolls on wrapping machines. In Denmark alone, the annual consumption of wrap foil is approx. 125,000 rolls. In all European countries, consumption is estimated to be at least 4.6 million. rolls. If each unit handles 500 rolls / year, there is a potential market of 9,200 units in Europe alone. Worldwide, there is an estimated potential market of at least 20,000-30,000 units. An actual market of 2000 units alone represents a value of more than DKK 100 million. Agriculture and machine stations use the foil rolls in practice. First, the foil rolls are delivered to the farm or machine station from the supplier, then the rolls must be unpacked
    DK 2020 01447 A1 2 boxes or other types of wrapping and placed on the shelves or racks of the wrapping machines before driving out into the field. This moving and placing of foil rolls is done manually by one or two people. Every time rolls have to be changed out in the field on the wrapping machine, there is only a manual effort as an option, because at present the weight of the foil rolls is the biggest work environment challenge, as each roll typically weighs 25 - 30 kg. The working environment legislation stipulates that it is not permitted for companies to allow employees to lift more than a maximum of 25 kg placed close to the body. If the legislation is exceeded, there is a risk of permanent damage to the persons who handle the foil rolls, as the handling of the rolls with placement on the wrapping machines often involves very inappropriate working positions.
    Changing foil rolls is also not something the operators are looking forward to, but at present they have no choice but to grab the foil rolls and place them on the wrapping machine, unless they have a helper available. There is an expectation that operators will find it easy to accept an easier method. Rolls weighing over 30 kg are not at all motivating for the operators. If there is a simple and easy-to-use auxiliary equipment, many will be very interested in it.
    In order to comply with the legislation, two people must be present when changing foil rolls, which is not realistic, as it will significantly increase the cost of packaging. Thus, in practice, changing rollers is often carried out by only one person, even if the method does not meet the working environment regulations.
    There is currently no knowledge of any methods or devices that solve the problem of handling foil rolls in connection with wrapping agricultural crops.
    Patent US 2008 121119 (A1) and CA 2620307 disclose a solution where a crane is arranged on a baler. At the end of the crane a simple gripping claw is mounted.
    DK 2020 01447 A1 3 Patent DE 20305207 directs a gripper The industry, where there is also a large consumption of foil rolls, the conditions are somewhat different, here foil rolls are used indoors and larger and heavier rolls are used which solutions have been developed to handle. The solutions may consist of mechanical devices, hand-drawn or mounted on a truck or similar vehicle. The manufacturers of foil rolls for agricultural purposes are limited in the size of the rolls they currently produce, as no rolls are produced heavier than 30 kg in order to be able to handle the rolls. If in practice it was possible to handle larger and heavier rolls, the manufacturers would produce larger and heavier rolls, which would make both production, transport and handling much more efficient. It will also mean that the rolls could probably be produced at lower costs, expressed in kroner per meter of foil. In future, more foil rolls, from several brands, will be produced from recyclable plastic foil. One of the methods to keep costs down and make the product attractive is to produce heavier rolls, make production more efficient and reduce costs. If one is to be able to handle the rolls that are already delivered today, with a weight of 25 - 30 kg safely and at the same time in the future be able to handle the heavier rolls, it presupposes that an efficient, flexible and safe method and a device for handling the rollers with minimal manual effort. Such a method and a device which can solve the above problem of handling foil rolls is not yet available on the market even though there is a very large potential.
    Incentives for investing in the invention are, firstly, a consideration for occupational safety, as there is a greatly reduced risk of occupational accidents when the operator no longer has to make inappropriate heavy lifts when changing foil rolls. Secondly, the invention means that in principle an extra man can be saved every time there
    DK 2020 01447 A1 4 foil rolls must be changed. The financial savings with this are quite significant when you take into account that rollers are often changed twice every hour. Thirdly, it is avoided that the rollers have to be delivered in cardboard boxes which subsequently have to go through a recycling process.
    Although there are solutions for industrial use, there are no immediate solutions that solve the challenge of simultaneously transporting foil rolls to the workplace, nor the challenge of developing a device that is so flexible that it can be used for all the various wrapping machines as used.
    There are wrapping machines that are only designed for wrapping one or more bales in a long row and there are other wrapping machines that only pack one bale at a time. There are also a significant number of wrapping machines that are built together with a round baler or a square baler.
    Object of the invention The object of this invention, which consists of both a method and an apparatus, is to be able to handle foil rolls in a safe and sound manner, which complies with the law, in connection with transport and change of foil rolls on wrapping machines. It must be possible to change rollers safely by only one person. Furthermore, the method and device must be able to be used for transport and placement of foil rolls, without manual lifting, on foil wrapping machines, which are intended for wrapping, preferably hay, straw and other crops.
    Description of the invention This object is achieved with a method of the type mentioned in the introduction, which is characterized in that the method comprises the following steps: - placing the pallet on pallet forks which form part of a handling device mounted rear or front mounted on a vehicle, there may be either the same vehicle towing the foil wrapping machine or a separate vehicle and the handling device comprising a crane for handling the foil rolls, which crane may be mounted on the vehicle or the foil wrapping machine,
    DK 2020 01447 A1 - transporting the foil rolls to a place of use, preferably a field - lowering the handling device at the end of the field or bringing it with you during work and lowering each time foil rolls are to be changed in the foil wrapping machine, 5 - when changing foil rollers the foil roll holder of the foil wrapping machine for enabling the placement of a new foil roll in the foil roll holder, - activating the crane from a rest position to an engaging position for placing a holding or gripping device mounted on a crane arm in contact with a foil roll on the pallet, - activating holding or the gripping device for holding the foil roll, - activating the crane arm to bring the foil roll held therein into position for placement in the foil wrapping machine, - placing the foil roll in the foil roll holder in the foil wrapping machine either by rotating the holding or gripping device or a vertical displacement depending on the foil roll holder orientation relative to the foil roll orientation on the pallet, - release of the holding or gripping device from the foil roll, and - return of the crane arm to the rest position, after which the above procedure steps can be repeated at the next foil roll change. to the foil roll holder.
    The device according to the invention is characterized in that the device comprises -pallet forks (2) connected to a pallet frame, -a quick coupler, preferably an A-frame which is rear- or front-mounted on a vehicle which can either be the same vehicle which pulls the foil wrapping machine or a separate vehicle, - a crane for handling the foil rolls, which crane may be mounted on the vehicle or foil wrapping machine and which crane has a crane arm with a rest position and an engaging position -a holding or gripping device mounted on the crane arm and which in the engaging position of the crane arm is in contact with a foil roll on the pallet, and that the holding or gripping device is arranged to hold and release the foil roll, and that the holding or gripping device is optionally arranged for rotation and / or displacement for placement of the foil roll in the foil roll holder of the foil wrapping machine.
    DK 2020 01447 A1 6 The invention solves a problem with lifting foil rolls onto packaging machines in agriculture. Without such a device for lifting foil rolls, the working environment rules cannot be complied with unless two people are present each time new rolls have to be applied. It will make the work more difficult and expensive.
    With the invention, one person can, in a safe manner, change foil rolls even with a greater weight in each roll than is currently the case. It saves both time and costs. The new method and device will make it more attractive to use recycled plastic in rolls that have a greater weight as it saves time and costs in all joints.
    The invention not only saves time, it reduces the risk of wear and tear on the body and accidents at work.
    With the new invention, an entire pallet of foil rolls is transported to the workplace.
    When changing rollers, this is done by placing the front-mounted unit which is equipped with a quick coupling in the field and the machine which must have changed foil rollers is driven to the unit which is equipped with a small crane which lifts the rollers into place without any manual work with lifting rollers.
    A quick coupler means that it takes less than a minute to set down the unit and hold it next to it with the wrapping machine for changing foil rolls. The device is mounted with pallet forks (2) so that the unit is able to grip and lift an entire pallet with foil rolls and transport them out to the work site. During transport, the pallet frame (2) is tilted backwards in the direction of travel to prevent the rollers from tipping forward and at the same time they are easier to catch with the grab arm (12).
    The device is intended for mounting on a vehicle either at the front or rear and the crane unit can be used separately, mounted on the wrapping machine itself. out during transport and during handling.
    DK 2020 01447 A1 7 At the top, the device is equipped with a crane, on which a gripper arm can be mounted which is operated either manually, with a vacuum or with an electric actuator. Alternatively, a pipe lock can be fitted for vertical lifting of foil rolls for vertical placement on wrapping machines. The gripping arm can be used for both vertical and horizontal placement of foil rolls. The gripping arms are typically constructed of thin and light steel plates that are curved so that they can grip around the outer circumference of a foil roll. The gripping arm can thus comprise two crescent-shaped plates provided with a closing mechanism which can be manual, or activated with an electric actuator or vacuum.
    Movements in the crane take place by means of one or more electric actuators which are activated by means of a control handle. As an energy source, a battery is located at the front of the unit. Alternatively, a motor can be placed on the device for operating the oil pump or generator.
    Foil rolls delivered to the yard or machine station are typically placed on pallets. At the bottom of the device, therefore, pallet forks are mounted so that the unit is able to lift an entire pallet with foil rolls and transport them out to the work site. At the workplace, you can choose to either unload the unit at the end of the field and drive to the unit every time you need to change foil rolls or to bring the device, which is located in front of the tractor during work, and put it off every time you need to change rolls. Using a quick coupler between tractor and device, it can be an A-frame means that it takes less than a minute to set down the unit and drive forward and hold next to it with the wrapping machine, for changing foil rolls. The device can also be located on the back of a loading unit which is used to place bales on a wrapping machine which wraps straw, hay or silage in one or more layers and in long sausages. The device is operated by means of a control handle which is operated by one hand and where the operator is always behind the foil roll for safety reasons.
    The present invention relates in a further aspect to the holding or gripping device comprising a gripping arm which comprises two crescent-shaped plates and which is provided with a closing mechanism which can be manually activated or activated by electric actuator or vacuum.
    The present invention relates in a further aspect to the holding or gripping device comprising a pipe lock which consists of two obliquely cut pipe halves where an actuator is mounted inside the pipe.
    In a further aspect, the present invention relates to the fact that the two pipe halves of the pipe lock can be adapted to different diameters of cores in the foil rolls, in that the pipe lock comprises replaceable pipe halves.
    The present invention relates in a further aspect to that between the crane arm and the holding or gripping device there is a lifting arm which connects the holding or gripping device to the crane arm.
    The present invention relates in a further aspect to the fact that a control handle is placed on the lifting arm in which all functions are controlled.
    The present invention relates in a further aspect to the fact that a towing arm is mounted with a slot between a pallet frame and a hydraulic piston mounted on the quick coupler of the vehicle, preferably an A-frame of a tractor.
    The present invention relates in a further aspect to the fact that the crane is mounted separately from the pallet forks and the pallet frame and is mounted directly on the foil wrapping machine. In a special embodiment, the device according to the invention comprises a front-mounted unit provided with pallet forks in a pallet frame (2) for the purpose of the unit being able to lift and transport an entire pallet with foil rolls (4) at a time.
    The foil rolls (4) are delivered from the supplier on pallets and “reloading” to the unit takes place without any kind of manual effort with lifting of foil rolls. The foil rolls (4) which are typically placed vertically on the transport pallet and wrapped with wrap foil.
    DK 2020 01447 A1 9 The pallet frame (2) can be rotated so that the foil rollers (4) tilt backwards in relation to the direction of travel with the purpose that the foil rollers (4) do not tip over during handling and do not fall off during transport.
    At the top of the unit is mounted a crane (5) with several mutually movable crane arms and with one or two turning devices which can be activated either manually or by means of one or more actuators which are supplied with energy from an accumulator located on the unit. The crane is also provided with one or more lifting devices and may be provided with projections on the outer crane arm.
    On one side in front of a main frame (1), the crane (5) has its innermost pivot point which is provided with a lifting device.
    A holding or gripping device may be in the form of a gripping arm (12), and this may be either mechanical (12) pneumatic (12a) or controlled by an actuator. The foil roll (4) is rotated from horizontal to vertical either by means of an actuator or by manual insertion.
    A holding or gripping device for vertical lifting can also be in the form of a pipe lock (14) which can be lowered into the core of the roller. By means of adjustable pipe sections, the pipe lock (14) can be adapted to roller cores with different diameters.

    20. A-frame In FIG. 1 shows that the unit is set off and stands on the main frame itself (1) which is located on a surface. The pallet frame itself (2), which consists of the pallet forks and the perpendicular upright frame, is rotatable. The pallet frame is turned over the lower left point, so that the rollers (4) tilt forward towards the tractor at an angle of 20 - 30 degrees. This
    DK 2020 01447 A1 11 angle prevents the rollers from falling off during transport and makes mounting the gripper arm on the foil rollers (12) easier. During transport, the unit is connected to the tractor (6) via an A-frame (20) which can be adjusted at the top with a hydraulic top link. The hydraulic top link is used to make pallet forks with frame (2) tilt backwards. The activation takes place by the wooden rod (9) pulling the upper part of the pallet frame (2) towards the main frame itself (1) when the hydraulic top rod is activated so that the piston is moved further out of the cylinder. A pawl locks the frame when it is in the desired position. When changing pallets, the pallet frame must return to the starting position, this is done by the hydraulic top link pulling the drawbar (9) all the way back so that the pallet is loose enough for it to be released with an actuator. Then the piston on the top pliers is pulled back into the cylinder and the pallet frame returns to the starting position via its own weight.
    The crane (5) has two arms, each of which can be adjusted in length and provided with two swivel joints. The crane has a total reach of about 2 m from the crane's innermost pivot point and out to the gripper arm (12). During transport, the arms can be positioned relative to each other so that the gripper arm (12) can be placed on the intermediate tractor and the unit on the left side in the direction of travel.
    The gripping arm (12) consists of two crescent-shaped halves (15) which enclose the foil roll (4) by 180-200 degrees. The two crescent-shaped halves (15) can be vulcanized on the inside both for the sake of gentleness and grip. The two crescent-shaped halves are connected by a hinge and are activated manually, with a vacuum or with an actuator. The use of an actuator provides the greatest safety, as an actuator can only be moved when it is supplied with power, which can only be done by an active action.
    The pipe lock (15) is intended for use instead of the gripper arm (12). The pipe lock is suspended in the same way as the gripper arm.
    The pipe lock (15) is used by placing the pipe lock in the current roller. When the pipe lock is placed in a roller, it is locked with the control handle. The actual locking takes place via an actuator. When using an actuator, the lock can only be activated by supplying power to the actuator, which is important for safety. Once the lock is in place and activated, the roller can be lifted. It can be lifted directly into place on wrappers, in cases where there are
    DK 2020 01447 A1 12 vertical location. When the roll hangs in a wire (19), it allows easy adjustment on the wrapping machine.
    In FIG. 2 shows that the main pivot point of the crane is located on the right side in the direction of travel. By adjusting the mutual lengths of the two arms, the crane can be adapted to many different combinations of ranges. The crane arm can be positioned so that the rollers are protected during transport.
    In FIG. 3 shows that the inner pivot arm is provided with a parallel guide so that the outer pivot point is always kept as vertical as possible, in order for the pivot force to be as small as possible. The crane has only one actuator (16) for lifting and lowering the two crane arms with the gripper arm at the end.
    When lifting a roller, the operator grasps the gripper arm (12) and places it in the middle of the foil roller (4) where after actuator, vacuum or manual lock (16) is activated and the foil roller is locked to the gripper arm (12) which hangs in the lifting arm (13). The gripping arm (12) is constructed of very thin and light steel plates and the lifting arm (13) itself is constructed of a light material so that the total weight of the lifting arm and gripping arm is made as light as possible and has a design so that the operator can easily set it on the foil roll with one hand.
    In FIG. 4 shows a detail picture. The steering is done with a steering handle (14) which is located on the lifting arm (13). The control handle can be moved quite slightly vertically relative to the lifting arm (13). When lifting the control handle, lift the foil roll up by activating the activator. To lower the arm, move the handle down. The crane turns when towing to one side or the other (effect as with power steering). Several finger-operated rotary switches may be mounted on the control handle, depending on the manual, actuator or vacuum embodiment.
    The guide is arranged and constructed for the purpose that the operator always stands behind the foil roll and guides it in place, which is chosen for reasons of safety and for convenience. The electrical connection to the activators in the gripper arm (12) and the lifting arm (13) is part of the “lifting wire” itself.
    GB 2020 01447 A1 13 When the gripping arm (12) grips the foil roll (4) and the roll is to be placed horizontally in the wrapping machine, turn the gripping arm (12) manually or by means of an activator. The foil roll can now, after it has been turned around and lifted with the crane to the correct height position, be placed on the wrapping machine with one hand on the control handle. More specifically, the following can be stated about the functions of the handlebar:
    1. When pulling up on the handle, lift the arm and the roller.
    2. When pulling down on the handle, lower the arm and the roller.
    3. When pulling horizontally away from the roller in the handle, follow the roller until the “arms” can not give more.
    4. When pushing horizontally against the roller in the handle, the roller moves away from the operator until the “arms” are pushed completely together.
    5. Gripper arm is activated with handle.
    6. Activation of rotation of the roller is done manually
    7. The crane arms themselves are rotated when the operator rotates the crane arms by hand
    8. Spring (18) at the top and bottom causes that when the handle is moved vertically up or down, the large actuator on the crane is activated.
    9. Cables can be avoided and a wireless transfer can be made to the control box by an accumulator. Figure 5 shows the pipe lock (15) which is inserted into the center of the foil roll for vertical lifting and vertical placement. The pipe lock consists of two pipe halves which are cut obliquely in relation to each other and inside the pipe is an actuator. When the actuator presses the two pipe halves against each other, a pressure will occur and the locking will take place. If the pipe lock, the upper pipe half just reaches above the roller, you can hold here until the lock is activated. There is very little resistance in the wire, just enough for the pipe lock to be retracted when it is released. Figure 6 shows the front view of the unit in front of the unit and tractor. Brackets for crane mounted on the right side are shown. The crane is turned manually. The unit consists of a top frame front and closed or partially closed side panels (17).
    DK 2020 01447 A1 14 The bottom consists of only two pallet forks which are used to lift a pallet with foil rolls. When the device tilts backwards during transport, the pallet or rollers are prevented from falling off. An inclination of 20 - 30 degrees is expected to be sufficient.
    Figure 7 shows the unit seen from above where the top and front are open. The sides and the rear part of the tractor are closed. The pallet forks are designed in connection with an A-Frame and with the help of the hydraulic top link the pallet frame (2) is tilted towards the tractor.
