COVERING SYSTEM FOR COVERING A SPACE, FOR example FOR STORAGE OF BULK GOODS, FOR example SILAGE, ASSEMBLY FOR THE COVERING SYSTEM AND A METHOD FOR FORMING A COVERING SYSTEM FOR COVERING THE SPACE
The invention relates to a covering system for covering a space, for example for storing bulk goods, for example silage, which space is formed between two opposite walls, wherein the covering system comprises one or more cloths, each arranged around a part of the space, wherein the covering system comprises a number of winding shafts, mounting means for the winding shafts and fastening means, in which each cloth is arranged on a winding shaft, each winding shaft being rotatably mountable on one of the walls by means of the mounting means, such that in a rest position each cloth is wound around a winding shaft and in a position of use each cloth is unwound at least partly from a winding shaft and can be attached with the fixing means on or near the opposite wall.
Such a system is known from the international patent application WO-A1-2012 / 006673, in which a covering system for covering a space for storing bulk materials is shown. The system from WO-A1-2012 / 006673 comprises a number of side wall modules, a number of which are equipped with a roll assembly. Each roll assembly comprises a roll around which a cover sheet can be wound between a stored and an extended condition.
A disadvantage of the system from WO-A1-2012 / 006673 is that a complicated coupling system is required to mutually connect the cover sheets.
Another known cover system is used to store animal feed for long-term use. The preparation of animal feed for storage is called "silage" in the field. During ensilage, a harvested product (such as grass) is collected and driven onto a pile (the "pit pile" or "pit") between two opposite walls. The pit pile is thereby firmly pressed. The silage pile is then sealed airtight with one or more layers of plastic. To properly fix the plastic, sand and soil are driven on the edges. The silage pile is then covered with the aid of the known covering system, comprising one or more cloths, for protection against animals and weather influences. Thereby successive cloths partially overlap each other. The canvases are held in place by ballast such as car tires, sand trunks or the entire pit is covered with soil or sand.
The known covering system has the disadvantage that covering is very labor-intensive. The separate cloths must first be positioned on site and laid ready to be pulled over the room. Subsequently, after pulling the loose cloths over the room, ballast must be placed over the cloths.
The removal of each cloth is also labor intensive, since the ballast on each cloth must be removed separately.
The cloths of the known covering systems also damage and wear quickly, because the cloths end up on a pile. Because the cloths lie in the open air and on the ground, all kinds of weeds grow through the cloths and vermin crawl through the cloths.
It is the object of the invention to provide a cover system according to the preamble, which at least partially overcomes the aforementioned drawbacks. Another object of the invention is to simplify the system from WO-A1-2012 / 006673.
To that end, the inventive covering system is characterized in that, in the position of use, successive sheets partially overlap each other.
Because the successive screens partially overlap, it is not necessary to provide a complicated coupling system for coupling adjacent screens. This makes the system according to the invention simpler than the system from WO-A1-2012 / 006673.
It is noted that with the system from WO-A 1-2012 / 006673 it is not possible that neighboring fabrics partially overlap. Therefore, the complex coupling means are required with this system.
With respect to the system known per se, these technical measures mean that each fabric is always in the correct position with respect to the walls and a fabric does not have to be protected with ballast. Also removing each cloth is less labor intensive, since no ballast needs to be removed. The cloth can also be rolled up neatly so that it does not make contact with the ground.
Another advantage of the system according to the invention is that it is a modular system that can be easily applied by a user by mounting the winding shafts with the mounting means on a wall of a storage space. The user can choose the number of wrapping shafts to be applied in accordance with a length of his storage space or silo and in accordance with a width of each cloth. Each cloth is preferably of such a length that the length is sufficient for a maximum width of conventional storage spaces or silos. When the silo in question is narrower than the maximum length of the cloth, the cloth is partially unwound in its position of use.
Yet another advantage of the system according to the invention is that it is safe for the user. Namely, the user does not have to climb on the stack of bulk goods or silage to apply the cloths thereon, but the user can pull a free end of the cloth with the help of a rope or the like from the opposite wall over the bulk goods and onto the fasten the opposite wall with the aid of the fasteners.
Yet another advantage of the system according to the invention is that the storage space per cloth can be released for removing bulk goods, for example silage, from the storage space with a depth which substantially corresponds to the width of a cloth. The remaining cloths do not have to be removed so that the bulk goods that are covered can remain covered.
It is noted that the width of each cloth can be chosen as desired, for example in accordance with a minimum depth of bulk goods to be retrieved from the storage space at a time. For example, a width that is between 1 and 4 meters, more in particular between 2 and 3 meters, has proved suitable.
It is further noted that the cloths can be made of any suitable material. The material is in particular sufficiently strong to withstand any tensile force and / or sufficiently strong to withstand animals such as birds, cows and / or small game and / or is UV-stable and / or is substantially flexible. The cloth may or may not be gas and / or liquid-tight. Technical textiles or geosynthetics in particular would be a suitable material.
It is further noted that successive cloths in the longitudinal direction of the opposite walls mean neighboring or adjacent cloths. Consecutive or adjacent cloths can be attached either to the same wall of the two opposite walls, or to different walls.
It is further noted that the overlap of adjacent cloths is achieved in particular by the fact that adjacent winding shafts partially overlap in the longitudinal direction of the opposite walls, so that in the position of use the cloths arranged thereon and at least partially unwound cloths overlap one another. The winding shafts here extend substantially parallel to the longitudinal direction of the opposite walls.
In a preferred embodiment of the cover system according to the invention, at least one of the mounting means is adapted to rotatably fix two facing ends of successive winding shafts. In particular, at least one of the mounting means is adapted to rotatably attach two end zones of consecutive winding shafts which face each other and which overlap each other with a certain overlapping length.
This greatly simplifies the mounting of the winding shafts on the wall, since only two mounting brackets are required for mounting two shafts. These mounting means also ensure that the overlapping area between successive cloths is always constant, whereby the cover system effectively minimizes the number of cloths. The overlap length with which the end zones overlap can be chosen as desired. This overlap length is preferably chosen such that the cloths wound thereon overlap each other in their unwound state with a suitable cloth overlap length.
It is noted that in this case each winding shaft is supported by two mounting means.
It is further noted that in particular the mounting means arranged at the end zones of the space can be adapted to rotatably attach one end of one winding shaft.
In another embodiment of the covering system according to the invention, each mounting means preferably comprises fixing means for rotatably fixing one end zone of one winding shaft or for rotatably fixing two end zones of adjacent winding shafts. The fixing means can be designed in any suitable manner. The fixing means can for instance comprise a receiving space, for instance an opening or recess, in which an end zone of a winding shaft can be rotatably received. Alternatively, the fastening means may comprise a protruding pin-shaped element, which pin-shaped element can be connected to a winding shaft, for example by arranging the pin-shaped element in a winding space, such as a cavity, in the winding shaft.
In another embodiment of the covering system according to the invention, the winding shafts are mounted on the wall by means of the mounting means such that adjacent winding shafts are not arranged in line with each other. By arranging the winding shafts not in line with each other, but instead shifting or displacing relative to each other, it is possible that the cloths wound on the winding shafts partially overlap each other in the position of use. Adjacent winding shafts can be arranged offset in any desired direction relative to each other. For example, adjacent winding shafts can be attached to the wall at a different height and / or distance from the wall.
Preferably, at least one of the mounting means in the or another preferred embodiment of the cover system according to the invention is adapted for mounting successive winding shafts at a different height. As a result of this measure, the mounting means makes better use of the available space on the wall. This measure also makes it possible for adjacent winding shafts and therefore the cloths wound thereon to be mounted on the wall with that mounting means, and therefore the cloths wound thereon to partially overlap. An advantage of a mounting means that determines the difference in height between adjacent cloths is that the height difference can preferably be constantly chosen between each pair of adjacent cloths.
Preferably, at least one of the mounting means in the or another preferred embodiment of the cover system according to the invention is adapted for mounting successive winding shafts with a different distance from the wall. This technical measure ensures a tight connection of successive screens close to the mounting means. This measure also makes it possible for adjacent winding shafts and therefore the cloths wound thereon to be mounted on the wall with that mounting means, and therefore the cloths wound thereon to partially overlap. An advantage of a mounting means that determines the difference in distance to the wall between adjacent cloths is that the distance difference can preferably be constantly chosen between each pair of adjacent cloths.
In the or another preferred embodiment of the cover system according to the invention, at least one of the mounting means comprises locking means for locking the rotation of each of the attached winding shafts. Locking the rotation is necessary to prevent a cloth from not lying tightly over the space after it has been attached to the free side with the aid of the fixing means on or near the other wall.
To that end, at least one of the winding shafts is preferably provided with a slot for applying the cloth to the winding shaft and at least one of the locking means comprises a pin-hole connection for cooperation with the slot.
The ensiled cattle feed or silage will decrease in volume over time. This will cause a canvas to lie less tightly across the room. To prevent this, in the covering system according to the invention, the fixing means are provided with tensioning means for tensioning the cloths. With the aid of the tensioning means, each cloth can be put on pre-tension. If the silage of volume has been reduced, this can be absorbed by the pretension on the canvas. If this pre-stress is not sufficient, the tensioning means can be operated by a user of the cover system to reset each cloth to the correct pre-stress. It is therefore clear that by pre-tensioning is meant both pre-tension and post-tension.
The tensioning means for tensioning according to the invention can in particular be used in combination with winding up the cloths. Thus, the cloths can first be wound tightly and then be further tensioned with the aid of the tensioning means.
In order to load each cloth equally over its width when biasing, the tensioning means comprise tubular elements, each of which can be attached to a cloth across the width of a cloth, and tension bands, which are connected to the tubular element.
The tensioning means are preferably connected thereto at some distance from the ends of the tubular elements. This allows adjacent cloths to partially overlap each other and gives a better load distribution on the tubular element.
The tubular element can for instance comprise connecting eyes or other connecting elements for connecting to the tensioning means. The connecting eyes or other connecting elements can, for example, be connected to it for displacement along the length of the tubular element.
For easy and unambiguous mounting, at least one of the mounting means preferably has a search surface, which search surface is intended for searching a position on a wall. A search surface may, for example, comprise an edge supported on an upper side of a wall.
The invention also relates to a mounting means as part of the covering system according to the invention. The mounting means may comprise one or more of the features explained above, in any suitable combination.
The invention further relates to a method for forming a covering system for covering a space, for example for storing bulk goods, for example silage, which space is formed between two opposite walls, wherein the space is covered with partially overlapping cloths, the method comprising the following steps to be performed in any suitable order: a). winding each of the cloths on winding shafts; b). mounting each winding shaft on one of the walls with the aid of mounting means, wherein the longitudinal axis of the winding axis runs parallel to the longitudinal axis of the wall; c). unwinding each cloth from the winding shaft until the space is sufficiently covered; d). locking with the aid of locking means of each winding shaft from which the cloth is unwound in step c); e) . attaching a free end of each cloth with the aid of fastening means to or near an opposite wall;
In the method according to the invention in step b), preferably, each winding shaft is mounted on the same wall. This makes it possible to use a mounting means according to an embodiment of the invention.
Preferably, in the method according to the invention in step b), each successive winding shaft is mounted at different heights.
Preferably, in the method according to the invention in step b), each successive winding shaft is mounted on the wall at different distances from the wall.
Preferably, in the method according to the invention in step e), after attaching a cloth to or near an opposite wall, the cloth is tensioned with tensioning means.
The method according to the invention preferably comprises the additional steps of: step f) unlocking the winding shaft locked in step d), thereby preventing the winding shaft from rotating; step g) rotating the winding shaft in a direction where the cloth applied to the winding shaft is tightened; step h) locking with the aid of locking means of the winding shaft unlocked in step f).
The invention furthermore relates to a silo, comprising a space formed between two opposite walls, which space is for instance adapted for storing bulk goods, for example silage, which silo is a covering system for covering the space according to one or more of the embodiments described above. comprises, wherein the covering system comprises one or more cloths, each of which is arranged to cover a portion of the space, the covering system comprising a number of winding shafts, mounting means for the winding shafts and fastening means, wherein each cloth is arranged on a winding shaft, each winding shaft is rotatably mounted on one of the walls by means of the mounting means, such that in a rest position each cloth is wound around a winding shaft and in a position of use each cloth is at least partially unwound from a winding shaft and can be attached with the fixing means to or near the opposite one wall, characterized in that in the position of use successively the following cloths partially overlap.
The cover system can have one or more of the features explained above in any suitable and desired combination.
In one embodiment of the silo, successive winding shafts are positioned relative to each other and overlap each other with a certain overlap length.
As explained above, it is hereby possible that the cloths wound on the winding shafts in the position of use partially overlap with a cloth overlap length.
In another embodiment of the silo, successive winding shafts are mounted on the wall at a different height and / or distance from the wall.
This is a practical embodiment in which successive winding shafts are not aligned with each other, but are instead offset or displaced relative to each other.
The invention will be further elucidated with reference to the following figures, in which: Figure 1 shows a cross-section of the known cover system in operating position;
Figure 2 shows a cross-section of a preferred embodiment of the cover system according to the invention;

Figures 8A - 8E show the cover system of figure 2 in perspective view, in which figure 8A shows all cloths in rest position, figure 8B shows a number of cloths in rest position and a number of cloths in operating position, figure 8C bringing a next number of cloths to operating position Figure 8D shows all fabrics in operating position, and Figure 8E shows the cover system in the operating position of Figure 8D from an opposite clamping side;
Figures 9A and 9B show a second embodiment of the cover system according to the invention, wherein Figure 9A is a perspective view and Figure 9B is a front view. The same numbers in the various figures indicate the same parts.
Figure 1 shows a cross-section of a known cover system 1 in operating position.
The covering system 1 is used in this figure to cover a space R formed between walls 2,3. The space R in the figure is filled with silage S. The silage is sealed airtight from the top of the space R with an airtight foil. A plurality of cloths 5 are then arranged over the top of space R and on the outer sides of walls 2,3. The cloths 5 are overlapped. Old car tires 4 are placed on the cloths 5. The car tires 4 ensure that fabrics 5 remain in place.
Figure 2 shows a cross-section of a preferred embodiment of the cover system 10 according to the invention. The cover system 10 is, just like the known cover system, suitable for covering the space R formed between two opposite walls 2,3. The space R is filled with silage S. Like the known covering system, the covering system 10 comprises one or more cloths 11. Each of the cloths 11 is adapted to cover a part of the space R. The cloths 11 here extend substantially transversely to the longitudinal direction of the upright walls 2, 3. The successive or adjacent sheets 11 arranged over the space R partially overlap one another in the longitudinal direction of the sheets 11. The covering system 10 comprises a number of winding shafts (12-1,12-2,.,., 12-n), mounting means 13 for the winding shafts 12 and fastening means 40, 41. Each cloth 11 is mounted on a winding shaft 12, each winding shaft 12 with the mounting means 20 being rotatably mounted on wall 3. In the rest position of the cover system 10, each cloth 11 is wound around a winding shaft 12. In a position of use, each cloth 11 is unwound at least partially from a winding shaft 12 and secured with the fixing means 40,41 on or near the opposite wall 2.
Figure 3 shows the mounting means 20 according to the invention. The mounting means 20 is adapted for rotatably mounting two facing ends or end zones of successive or adjacent winding shafts. To that end, the mounting means 20 comprises two winding shaft holders 21 and 22, both of which are provided with an opening or recess 23, 24 for passage or receiving an end or end zone of a winding shaft. The mounting means 20 also comprises a mounting plate 25 for mounting on a wall. Because the openings 23 and 24 of the two winding shaft holders 21 and 22 are mutually displaced, the mounting means 20 is adapted for mounting successive winding shafts at a different height. This is made clear in the figure with the different distances D1 and D2. The mounting means 20 is also adapted to attach successive winding shafts with a different distance to the wall. To this end, the openings 23, 24 are arranged at a mutually different distance D3, D4 from the mounting plate 25 on the winding shaft holders 21, 22.
Holes 26 and 27 are also provided on the mounting means 20, which holes form part of the pin-hole connection for locking the rotation of the winding shafts.
As can be seen from Figure 3, the fixing plate is provided with three holes 50 in each case near all the corner zones thereof. Screws or bolts can be provided in the holes 50 for mounting the mounting means 20 to a wall. An advantage of three holes, one of which is arranged at a different horizontal position and one at a different vertical position, is that when one of the holes is in register with a reinforcement in the wall, the remaining holes 50 can be used for fixing the mounting means 20 to the wall.
Figure 4 shows another view of the mounting means according to Figure 3. Here, the mounting means is shown from a rear view of the mounting plate 25.
Figure 5 shows the mounting means 20 to which two facing ends or end zones of successive winding shafts 12-1,12-2 are attached. Cloth 11-1 and cloth 11-2 are wound on winding shafts 12-1,12,2. For clarification, both screens 11-1,11-2 have been made transparent. In this figure it is shown that when both cloths 11-1,11-2 are unwound, the cloths 11-1,11-2 partially overlap. This is because the winding shafts 12-1, 12-2 partially overlap. Both winding shafts 12-1, 12-2 are enclosed in the openings 23, 24 by means of a closing plate 28, 29, which are fixedly mounted on the winding shaft holders 21 and 22 with a screw connection. The rotation of the winding shaft 12-2 can be locked by the pin 30, which can be inserted into a hole 27 through a corresponding hole in closing plate 29. The pin 30 herein cooperates with a slot in the winding shaft 12-2, which slot is also intended for feeding through a string of the cloth 11-2. In addition, the pin 30 can also cooperate with holes provided in the winding shaft 12-2. Winding shaft 12-1 can be locked in a corresponding manner.
Figure 6 shows a part of a side view of the cover system 10 in mounted condition on a wall, in which the cloths 11-1, 11-2, 11-3, winding shafts 12-1, 12-2, 12-3 and mounting means 13 are shown. With the aid of the mounting means 13, therefore, a covering system 10 can be obtained in a simple manner, wherein the cloths 11-1, 11-2, 11-3 are partially overlapping in the unrolled state.
Figure 7 shows a part of a side view of the cover system 10 in mounted condition on a wall 2, in which the tensioning means are shown. The tensioning means are formed by the tubular elements 40 and tension bands 41. Each tubular element 40 is attachable over the width of the cloth 11, in particular at a free end thereof, preferably via a tendon-slot connection or by receiving a tubular element 40 in a hem of a cloth. The straps 41 are attached to each of the tubular elements 40 and can furthermore be coupled to a bottom side of the wall 2. By applying the tubular elements 40, the force exerted by the straps 41 will be uniformly distributed over the width of the tubular element 40 and consequently over the cloth 11.
Figures 8A - 8D show the cover system 10 according to the invention in perspective view. In figure 8A the cloths are shown in the wound state. In figure 8B a first part of the number of cloths 11 is unwound and attached to the other wall 2. These are the cloths 11 of the winding shafts 12-2, 12-4 and 12-6 fixed more or more near the top of the wall 3. In Fig. 8C, the cloths 11 are unwound from the winding shafts 12-1, 12-3 and 12-5, which are arranged further down or further from the top of the wall 3. These cloths 11 overlap the previously unwound cloths and must therefore be unwound thereafter. In figure 8D, all screens 11 are shown in their unwound state.
As can be seen from Figs. 8A - 8D, the space R is accessible from one side for removing silage S stored therein from that space. When silage is removed from the space R, it is advantageous if the cloth 11 which the silage to be covered by space R is wound. In this way the silage is accessible from above, so that it can be cut or milled. If this concerns a cloth 11 which is overlapped by another cloth, namely one of the cloths 11-2, 11-4 and 11-6, the overlapping cloth 11-1, 11-3 or 11-5 is first wound up, or the tension thereon is released by further unwinding it or by releasing the tensioning straps, after which the respective cloth 11-2, 11-4 and 11-6 can be wound up. After winding up the respective cloth 11-2, 11-4 and 11-6, the previously wound or relaxed cloth 11-1, 11-3 or 11-5 can be unwound or tensioned again, so that this cloth 11-1, 11-3 or 11-5 covers the silage below.
Figure 8E shows the span side of the silo. This shows that, as described above, each cloth is provided with a tubular element 40 at its free end. Fastening eyes 42 are provided at approximately 1/3 and 2/3 from one end of the tubular element, which eyelets are connected to one end of the straps 41. By arranging the fixing eyes 42 at 1/3 and 2/3 of the length of the tubular element, it is ensured that successive cloths can overlap each other and that there is a good force distribution. The fixing eyes can be movably connected to the tubular element 40, so that the location thereof is adjustable. The tensioning straps 41 are connected to the wall 2 at their other end. The cloths can be tensioned with the aid of the tensioning straps 41 and ratchets 43 connected thereto.
Figures 9A and 9B show a second embodiment of the cover system according to the invention. In this embodiment, adjacent winding shafts 12-1 ... 12-6 are lower in each case, or further from the top of the wall 3 fixed to the wall. As a result, each time a subsequent fabric 11-x + 1 can partially overlap a previous fabric 11-x. An advantage hereof is that the cloths 11 can be unwound and wound up in sequence. As a result, when winding up cloths for releasing a part of the silage, it is not necessary for another cloth to be wound up first or, on the contrary, to be unwound for it to hang loose. In this embodiment, all winding shafts are attached thereto at a substantially equal distance from the wall 3 and only the height is different. The fastening means 40, 41 are also each attached to the other wall 2 at a different height. These can alternatively be attached at the same height.
It is noted that the invention is explicitly not limited to the described and shown preferred embodiment. The invention extends generally to any embodiment that falls within the scope of the appended claims as seen in the light of the description and the accompanying drawings. For example, it is not necessary that all mounting means are mounted on one wall. The mounting means can for instance also be mounted alternately on the walls.
The covering system according to the invention is expressly not limited to covering a space for storage of silage. The cover system is suitable for covering any space that is formed between two opposite walls.
