Method and apparatus for unloading bales Förfarande och anordning för lossning av balar

The invention relates to a method for unpacking bales or similar packages according to the preamble of claim 1, and in particular to a method by which unpacking of bales can be performed by a movable device which prevents bale binding yarns and wrapping material from entering the unpacked material. The invention further relates to a bale unloading device according to the preamble of claim 7.

It has previously been known to mechanically unpack, for example, bales of feed, pulp, cotton, waste paper, etc. or the like, in which the packed material is first tied by suitable binding means, such as binding yarns, hoops or the like, into a tight bale which can be substantially rectangular in shape. faceted or circular so-called. round and then in some cases wrapped in a suitable wrapping material, such as a stretch film or paper wrapper to protect the contents.

One device for unloading bales is known e.g. DE-A-41 05 149, which discloses a bale unloading station comprising a conveyor and means mounted thereon for cutting bale binding yarns and means for unwinding a two-part protective wrap around the bale, i.e. separately placed on the upper and lower surfaces of the bale. More specifically, the winding means of the protective wrapper comprises a rotatable arm provided with spikes that can be pushed out so that the wrapper engages around the arm and can be pulled into the arm so that the wrapper can be removed around the arm. The position and position of the arms can be adjusted according to the size and position of the bale on the conveyor track.

. However, the weakness of the proposed solution has been that it does not actually remove the ·· binding or support wires around the bale. In addition, the arrangement is complicated in structure and comprises numerous movable parts which are easily jammed e.g. haystacks or similar material packing between parts. Still, the device is decelerating due to a number of different work steps. One significant disadvantage for agricultural use, for example, has been the fixed, space-consuming conveyor-type installation of the device.

Various other also permanently mounted binding yarn removal devices are disclosed in F1 patents 90849 and 91378. One device for removing binding paper bales and collection cardboard bale wires adapted to bale tongs is disclosed in F1 patent 90030. However, the problem with the above disclosures is that and removed, they are also not suitable for removing the wrapper protecting the bale or similar package.

The weakness of the proposed solutions has been that they did not provide a sufficiently simple and easily accessible solution to both cut and remove the connecting wires and remove the protective wrap around the bale, and which could be adapted to be moved, e.g., to a tractor front or rear loader or to a bridge crane or similar. Thus, unloading of bales on farms, for example, still takes place mainly by hand.

The object of the present invention is to obviate the drawbacks of the prior art and to provide a completely new solution for unpacking various bales and similar packages, which bales or packages can vary in shape and packaging materials. The solution according to the invention provides a bale unloader and a method for unloading bales of varying shapes so that the yarns and the wrapping material do not mix with the material to be unloaded from the bale. The device can be installed as a mobile device, easy to use, simple in structure, fast and reliable.

It is a further object of the invention to provide a bale unloader and a method for unloading bales which collects the binding yarns and the wrapping material and by means of which they can be assembled at the desired location and thus prevented from passing with the packed material, e.g. to an animal feeding table.

It is a further object of the invention to provide a bale unloader which can be mounted, for example, on a tractor's front or rear loader, or on a hook of a bridge or control crane or the like.

It is a further object of the invention to provide a device by means of which one and in some cases several bales can be picked up at a time and moved from optional locations and even long distances.

Yet another object of the invention is to provide a method and a means for carrying it out, by means of which bales or similar packages of varying size, shape, content, binding yarn and wrapping material can be unpacked.

The invention is based on the basic idea of providing the device with suitable means for gripping and suitably lifting or otherwise moving the bale, as well as means for cutting the bale wrapper and / or binding yarns and means adapted to collect and retain the binding yarns and wrapping material while removing the baled material. a device is provided between which the bale can be easily unloaded at the desired location and the binding yarns and the wrapping material can be differentiated from the baled material.

More specifically, the method according to the invention is mainly characterized by what is stated in the appended claims 1 to 6 and in particular in the characterizing part of independent claim 1. The device according to the invention is mainly characterized by what is stated in the appended claims 7 to 15 and in particular in the characterizing part of independent claim 7.

According to a preferred embodiment of the invention, the unloading device comprises at least one arm arranged to be moved per bale, the end of which has one or more suitable protruding means adapted to grip the wrapping material surrounding the bale and preferably to protrude through the wrapping material surrounding the bale. Such a protrusion means may consist, for example, of a suitably shaped spike or toothing, such as a sawtooth pattern, adapted to obtain a firm grip on the wrapping material, but from which the wrapping material can easily be removed after all the baled material has been unloaded.

The device further preferably comprises suitable yarn and wrapping material collector / collector means located at the top, which collects the yarns cut in a suitable knife means and in some cases also the bundle of the unwound wrap and prevents them from falling out of the unloader with the baled material. According to one alternative, the means for collecting the binding yarns comprise finger means moving over one dimension of the bale and, according to another alternative, spool means rotatable in a plane substantially perpendicular to the plane of the bale. According to an alternative, the device is provided with helical collector means adapted to be rotated in a plane parallel to the surface of the bale facing them. If necessary, the helical means can be dimensioned in such a way that they are able to tear the wrapping material around the bale and wrap it around itself and, accordingly, to cut the binding yarns, so that no separate knife means is required.

According to a preferred embodiment, the device comprises support members between which the bale is arranged to be inserted and spike means extending from the support members or similar projections adapted to pivot towards the bale and extend through the wrapping material and thus retain the wrapping material in connection with the device. At the same time, the means for collecting the binding yarns or the like, such as suitable spooling means, are adapted to prevent the yarns from leaving with the material.

According to a preferred embodiment, the distance between the support means is adjustable and according to another embodiment, the angular position of the at least one support means relative to the body part of the device is adjustable.

According to one embodiment, the binding wires and the knife opening device cutting the wrapper are fixedly mounted separately from the device, e.g. on the ground, on the wall or even on the side of the trailer, so that the bale in the unloader can be pressed against the blade means to open the bale. According to another alternative, the unloading device is provided with a sharp means adapted to be moved across the wrapper and the wires. According to yet another alternative, the blade means is arranged so that it can first be pushed in its folded position through the bale, and then or during the push-through can be opened in a rain-shaded position to the position in which it is adapted to cut the bale open.

The operation of the device according to the invention begins when the bale is placed between the support means of the device. The support means may first be pivoted to the open position, after which the bale is placed between them and at least one support means is pivoted or moved towards the bale, whereby the spike or similar protruding means placed on the support means engages the wrapping material, e.g. According to another form, the device is provided with suitable rotatable roller means which allow the support means to be pressed onto the sides of the bale. The provided cantilever means, mounted in the vicinity of the ends of the support means and adapted to pivot, such as the tines, pivot towards the bale and grip the wrapping material when the bale is raised.

Next, the binding yarns are cut and the wrapping material is cut open on at least one side thereof. It can be performed, for example, by pressing the bale supported by the support means against a suitable fixed or movably mounted blade means. According to an alternative, the blade means arranged as part of the unloading device is moved across one dimension of the bale so that when it moves it cuts the binding wires and cuts the wrapper open. According to yet another alternative, a sharp means is used which is pushed through the bale and in which the openable, umbrella-like one or more cutting means provided cut across the wires on the opposite side of the bale and open the wrapper.

Next, the material to be unloaded is most preferably dropped between the support means while the wrapper and yarns are retained in the cantilever means of the unloader and in the linearly movable or rotatable collecting or collecting means. These "bale wastes" can be removed from the device or they can be allowed to accumulate in several bales and later removed in larger batches.

The invention provides considerable advantages. For example, equipping a conventional front or rear loader of a tractor or similar implement with a unloading device according to the invention provides a movable bale handling unit with which the bale can be moved and then unloaded at the desired location so that the binding yarns and wrapping material do not mix with the baled material. forward. The same device is suitable for unpacking bales and similar packages of varying size, shape, content, binding material and wrapping material. Unloading bales is much easier and lighter compared to the most commonly used and especially manual solutions. Compared to known mechanical solutions, the equipment required for unloading the bale is simpler and faster and more versatile. The unloader according to the invention collects the binding yarns and the wrapping materials, whereby the waste accumulated from them can be easily collected in one place reserved for them either automatically or by removing it manually from the device and thus the general cleanliness of the unloading place increases.

The invention and its other objects and advantages will now be described, by way of example, with reference to the accompanying drawings, in which like reference numerals in the various figures refer to like features. In this regard, it is to be understood that the following exemplary disclosure is not intended to limit the invention to the specific embodiments set forth herein, but rather to encompass all modifications, equivalents, and alternatives within the spirit and scope of the invention as defined by the appended claims. In this context, it is further noted that the term bale refers to all packages in which the material to be packaged, such as animal feed, waste paper, pulp, cotton, pulp, is bound, for example, by a suitable wire, rim, bandage or the like in a rectangular shape or round bale. wrapping material such as plastic stretch film, wrapping paper, paperboard or adhesive paper, or a combination thereof. The term binding wire is understood to mean all possible means used for binding the material, such as various plastic or natural fiber cords, metal wires, various rims and so on.

Figure 7 is a front view of the device of Figures 5 and 6.

Figure 8 shows a preferred embodiment of the cutting means.

Figure 9 shows another cutting means.

Figure 10 shows another detail of the invention.

Figure 1 shows a bale unloader 10 according to the invention. It comprises an upper frame beam 12, which together with another corresponding upper beam and two other upper frame beams 13 (see Fig. 2) passing between them, a frame frame 11 on which the bale unloader equipment 10 is mounted. Attachment means 14 is suitably attached to the frame frame 11, by means of which the unloading device 10 can be attached to, for example, the front or rear loader of the tractor. In addition, a special fastening ring 15 is shown, by means of which the unloader can be fastened, for example, to a bridge crane, a forest loader or a similar hook.

In addition, the apparatus includes collectors or collectors 22 for yarns and wrapping material adapted to be moved over or across the surface of the bale to collect the yarns, rims, or the like used to tie the bale. In the case of Figure 1, the collecting means 22 are arranged immediately below the frame and move in a straight line towards each other, i.e. one collecting means 22 from one edge of the device and the other from the other, whereby a bundle of wires is collected in the middle of the device. The movement of the collecting means can be effected, for example, by a suitable hydraulic drive means, such as a cylinder means or a shaftless cylinder (not shown), or they can be operated manually, e.g. by a suitable wire means or the like.

The exemplary device according to Fig. 1 further comprises pivotable support arm means 16 articulated at its upper end to the frame frame 11. The pivoting of the arms 16 is shown to be performed by means of hydraulic cylinders 18 and lever transmission 19. Of course, other suitable means for turning the support arms 16 can be used, and the support arms 16 can be arranged to pivot towards the central part, i.e. towards the bale between them, also when the device is lifted by the bale and / or the weight of the device. In Fig. 2, the arms are shown made in the shape of a frame 17, but they can also be of other shapes, e.g. a T or L shape or straight rod means extending from the frame.

According to an alternative, the movement of the collecting means 22 and the movement of the pivoting arms 16 facing the bale are adapted to be provided e.g. by the same cylindrical means so that while the arms 16 press against the piece the movement of the collecting fingers over the bale surface. This can be realized, for example, by attaching one end of the cylinder means 18 to the joints 19 of the arms and the other end to the moving means of the collecting means 22 (not shown).

The ends of the pivot arms 16 acting as support means, in this case the lowest support iron 17 'of the frame structure 17, are provided with suitable spike means or projections 20 extending towards the center of the device. The spikes are adapted to protrude and hold the packaging material, such as stretch film or cardboard. when the contents of the bale are dropped or otherwise removed between the support arms 16. In the case of Figure 2, the number of spike means is shown as 4 / arm, but a suitable number of spike means / arm can be, for example, between 2 and 8 spikes.

Fig. 2 shows the device corresponding to Fig. 1, but in a simplified perspective view without the drive and fastening devices above the frame frame 11 and the articulations of the support arms 16. The figure shows the bale 8, as well as the broken wires 9 tightened around the bale. In addition, a knife means 24 for cutting the wrapping material and the binding wires 9 is shown, which in the case of Fig. 2 is mounted separately from the device 10. The knife 24 may be fixed to the ground or other suitable base to the side of the trailer or similar.

Figures 3a and 3b show the operation of a preferred embodiment of the invention. The bale unloader is installed for you to turn! from the representation of the device of Figures 3a and b, it can be seen that only one of the support means pressing against the piece and provided with spike means 20, i.e. the support arm 34, is adapted to be pivoted and that the second support arm 32 is fixed, i.e. integral with the device body. . Figure 3a shows the device in a position in which the bale can be moved to the unloading site after it has been gripped.

In the situation of Figure 3b, the baled material has already fallen out of the wrapping material. The wrapping material and the lanyards shown on the broken line are adhered to the spike means 20 and the collection means 22 of the device. The second support arm 34 is turned slightly open to facilitate the drop of material.

Figure 4 shows an alternative embodiment for providing at least one movable support arm. The support arm 44 is movably arranged relative to the body portion 45 so that the distance between the fixed support arm 32 and the movable support arm portion 44 is adjustable. The hydraulic cylinder 43 is exemplified as the movable member, but other solutions known to a person skilled in the art are also possible.

Figure 4 further shows alternative binding wire collecting means consisting of spirals 46 rotatable about a vertical axis. The spirals lift the wires or the like off the surface of the bale as they rotate and retain them as the baled material exits between the support arms 31 and 44. Viewed from the front, the device according to Fig. 4 may correspond, for example, to the basic structure of the device shown in Fig. 7, being in the shape of a T-letter turned downwards.

In some cases, the spirals 46 are furthermore adapted to cause a tension in the binding flanges to cut them and to tear the wrapping material around the bale, thus eliminating the need for a separate knife means.

Figure 5 is a schematic side view of an embodiment 50 of a bale unloader according to the invention. The device 50 comprises a body part 52 comprising means 31 for attaching the device 50 to e.g. a tractor and abutment means 51 fixedly mounted on the frame means to support one side of the bale 8 during transport and / or unloading .

The device 50 further comprises, with respect to the body part 52, an arm means 54 as shown in Figure 5, at the outer end of which a suitable sleeve means 56 is placed. The dimension, i.e. length, of the arm means 54 is preferably adjustable and the adjustment can be fully manual and locked, e.g. or it is performed e.g. by means of a cylinder solution as shown in Fig. 4.

A support arm means 58 is arranged inside the sleeve means 56 at an angle and preferably at an angle of 90 ° to the arm means, at the lower end of which suitable rotatable roller means 60 may be arranged. The support means 58 is arranged inside the sleeve means 56 so as to be raised and lowered by the arm portion 54 regarding.

It should be noted that although in Fig. 5 the sleeve means 56 and thus the support arm means 58 are mounted at a fixed angle with respect to the arm means 54, the device can be easily equipped with a suitable drive device such as a hydraulic cylinder to adjust the angular position of the sleeve and thus the support arm 58.

In addition, Fig. 5 shows collector means 63 for binding yarns, the tips of which in this embodiment are adapted to pivot upwards, i.e. the collector means are adapted to rotate in a plane substantially perpendicular to the upper surface of the bale 8 and thus collect and retain the yarns. pieces, but other numbers are possible, depending on e.g. the size of the bale 8, the number and location of the binding yarns 9 used and the size and design of the collecting means, i.e. the dimension.

The spike means 61 and 62 according to the invention shown in Fig. 5 which penetrate and thus retain the wrapping material are shown to be pivotable between two different positions. This feature will be explained in more detail in connection with the description of Figure 6.

Fig. 6 shows a device almost identical to the embodiment according to Fig. 5 in its second operating position, i.e. with the support arm means 58 lowered. The differences in Fig. 5 are mainly the structure of the support means 51 'and the collecting means 63'. In this embodiment, the collector means 63 'rotatable about a horizontal axis are arranged in a spherical shape, whereby the pick-up ability of their wires is particularly good. Such Polish wire collection means are known per se to a person skilled in the art and will therefore not be explained in more detail in this context.

Figure 6 shows in broken lines the position of the spike means 61 and 62 when the bale is being placed in the unloader between its support means. The spike means are then preferably in an upright position, i.e. "upside down" with respect to the movement between the bale and the support means, and thus the support means 51 and 58 can be easily placed on two sides of the bale. The spike means 61 and 62 are adapted to pivot towards the bale 8 and pass through the wrapper when the unloader is lifted. The tines can also be operated by means of a suitable drive means, such as a string release, but in the most common cases they can be of a freely pivoting pattern, whereby the relative movement between the bale 8 and the unloader 50 causes them to pivot to the required position.

Figure 7 is a front view of the device corresponding to Figures 5 and 6. The figure illustrates the roller means 60 abutting against the bale and the possibility of positioning the spike means 62 relative to the roller means 60. As can be seen from the figure, the spike means 62 are still in an upright position and only the wide wounds are "co-haired" along the surface of the bale, as the shank means 58 has not yet fully lowered to its lower position.

The support arm means 58 may also be fixedly arranged with respect to the sleeve means and the rod means 54, the support means 51 according to Fig. 5 preferably also being a rotatable roller means and the baling between the support means is effected by pressing the unloading device inside a suitably adjusted unloading device. However, such a structure requires more accuracy from the user than the solution presented above. Instead of roller means, suitable means sliding along the surface of the bale can also be used.

Figure 8 is a partially sectioned perspective view of an embodiment of a cutting means. In this case, the sharp means 40 for cutting the wrapping material surrounding the bale and usually also for cutting the binding wires is mounted at the lower edge of the second support arm of the unloading device. The blade 40 is adapted to be moved across the width of the bale along the guide means 42. The movement of the blade means can be effected, for example, by a shaftless hydraulic cylinder or a conventional cylinder means, or e.g. by manually pulling the blade along the guide 42, e.g. by means of a suitable string means or by hand.

The blade means 70 schematically shown in Fig. 9 and mounted on the upper body of the device (not shown) and adapted to protrude through the bale 8 comprises a blade arm and at least two blades 72 extending therefrom. The figure shows the blade means in broken position in the position of the bale 8. The blades 72 are then turned against the arm 74. The blades 72 penetrating the bale, shown in solid line, are in the open position, and when moved upwards they cut the yarns 9 and open the wrapper.

According to one alternative, the basic principle of the cutting means is the same as that shown in Fig. 9, but it is adapted to be opened already inside the bale, i.e. the blades 72 are adapted to cut the wires and cut the wrap open as they protrude through the bale 8. Depending on the material to be cut, a suitable number of blades 72 may be, for example, between 1 and 8 blades, but more blades may be used. According to another alternative, a suitable blade means is inserted through the bale, which does not have any opening blades, but which is adapted to cut the binding yarns, e.g. by moving or rotating it laterally.

Fig. 10 is a partial view of Fig. 5 showing another detail of the unloading device. It shows a body part 52 of the device according to Fig. 5, in connection with which and preferably through it the first Support Arm 53 (shown in partial section), in which the abutment means 51 are mounted, is movably mounted as indicated by the arrow. In addition, a locking pin means 55 is provided, by means of which the dimension of the support arm 12 100961 53 is adjusted. In addition to adjusting the general dimensions of the device, the arrangement shown makes it possible, by lowering the arm 53 completely to the lower position, to provide a support member which can be used to grip several bales at the same time.

The operation according to an embodiment of the bale unloader according to the invention begins when the bale 8 or the like to be unloaded is placed between the support arms of the device, such as 16. The arms are turned or moved towards the bale, whereby the spikes 20 or similar members adapted to grip the wrapper penetrate the wrapping material and in some cases also support the bale between the arms.

Next, the wrapper is cut open on at least one side, e.g. by a suitable blade means, such as by pressing the bale against a fixed separate blade 24 or by a movable blade means mounted on the unloader, such as 40 or 70, and at the same time the tie wires 9 or the like are cut.

According to an alternative, the collecting means 22 are moved towards each other, whereby the binding yarns 9 and the wrapper accumulate in a bundle between the collectors. According to another alternative, rotatable, winding collecting means are used. The rotation can be performed, for example, either in a forging substantially perpendicular to the bale or in a plane substantially parallel to the surface of the bale.

The support arms 16 or 44 can be slightly opened so that the material between them, such as animal feed or the like, can more easily fall downwards while the wrapping material and binding yarns remain in the bale unloader retained by the collectors 22, 46, 63 or 63 'and the tines 22 or 61 and 62, from which they can be removed at the appropriate stage and place. According to an alternative solution, the packaging materials can be collected from several bales in the unloader and removed only, for example, every tenth bale.

According to another alternative, unloading is initiated by placing the rotatable roller means 60 at the end of the movable support arm 58 of the bale unloader 50 on the upper surface of the bale 8 and moving the unloader over the bale so that the roller means eventually crosses the other edge of the bale. 56. The function may be arranged so that no drive is required, but the support arm means 58 moves down the sleeve 56 under the effect of gravity. The movement in the other direction is effected by pressing the device, e.g. with a tractor loader, whereby the arm ,, 100961 13 58 moves upwards in the sleeve. This can be done, for example, against the top surface of the next bale. When the roller means has reached the lower edge of the bale, the device is raised, whereby the spike means 61 and 62 turn towards the bale 8 and adhere to the wrapping material. Next, the cutting and winding steps of the yarns and the wrapper as well as the actual unloading of the bale are performed. The advantage of such an arrangement is that it is easy and quick to place on a bale without particularly precise "aiming work".

According to an alternative, the arm means 58 is locked fixed to the sleeve means 56, whereby the device is simply pressed onto the bale to be unloaded. For example, in the case of Fig. 5, it may then be advantageous that the support means 51 is also a rotatable roller, whereby it is easier to place the unloader on the bale.

The invention thus provides an apparatus and a method by means of which the unloading of bales of varying shape and size is made much easier and faster, and the binding yarns, wrapping materials and other possible materials used in baling the bale can be removed from the baled material. The equipment is simpler in construction, but faster and more versatile.

It should be noted that the above examples of embodiments of the invention do not limit the scope of the invention as set forth in the claims. From the above description and the drawings, it is obvious to a person skilled in the art, for example, to use suitable grippers with openable and closable jaws as gripping means for the wrapping material instead of the spike means described in the examples. Suitable pliers can also be used to collect the yarns. Furthermore, it is obvious to a person skilled in the art that the unloading equipment according to the invention can be equipped with e.g. wheels and mounted on a working machine as a towed unit.
