Description

1 A Storage Assembly The invention relates to a storage assembly for elongated piece goods. Storage assemblies for elongated piece goods made of wood, especially wooden boards, wooden beams, wooden strips and/or wooden slats are known. Several elongated piece goods are stacked into a package of piece goods, with elongated piece goods being arranged above one another and next to one another in the package of piece goods. US Pat. No. 5,088,533 A discloses a storage assembly with several storage levels. JP 2002 104 650 A discloses a paternoster cross conveyor, comprising a plurality of support elements and a push-out member for pushing out the piece goods from the paternoster cross conveyor. DE 20 54 831 A describes a storage cross conveyor with a lever arm arranged on one end of the storage cross conveyor. GB 2 172 867 A concerns a storage assembly with several storage levels for conveying pallets. FR 2 223 945 A shows a storage assembly for storing baguettes. CH 664 710 A shows a paternoster conveyor as a first elevating cross conveyor which conveys the boards to different levels of the storage assembly which are stacked above one another. WO 99/037 564 A describes conveyor belts stacked above one another which are each height-adjustable at both ends. Wood, which is a naturally grown material, has a tendency towards self-warping up to a certain degree, wherein the self-warping of an elongated piece good can differ from the self-warping of other elongated piece goods. The disadvantageous aspect in this storage assembly is that as a result of the mutually differing self-warping of the piece goods a high load can arise on an individual one of the elongated piece goods, and/or the arrangement, especially the vertical and/or perpendicular parallel arrangement of the piece goods, is possible only with difficulty and/or hardly at all. As a result, the effort and/or the likelihood of damage during the conveyance into the storage assembly, during the storing and/or during the withdrawal from the storage assembly are high. It is similarly disadvantageous that the need for space of the storage assembly can be high and the sequence of removal of the elongated piece goods cannot be changed or only with a considerable amount of effort.

2 It can also be disadvantageous that a subsequent expansion is hardly possible in these storage assemblies, with the storage assembly having to be planned and built with a predetermined storage size and/or storage capacity. This makes the adjustment of the storage assembly to changing demand and/or changing production planning more difficult. It is therefore the object of the invention to provide a storage assembly for storing elongated piece goods, with which the mentioned disadvantages can be avoided, with which the storing and removal of the elongated piece goods can occur in a simple, rapid and flexible manner with a low amount of load and with a low amount of likelihood of damage to the piece goods, and with which it is possible to react in a simple way to a changed need for storage and/or changed production planning. This is achieved in accordance with one aspect of the invention by a method for storing elongated piece goods, especially made of wood, with the elongated piece good being conveyed in a first elevating cross conveyor on one first side of a storage assembly, with the first elevating cross conveyor lifting the elongated piece good in a predetermined manner up to one of at least two storage levels, and with the elongated piece good being conveyed at the predetermined storage level out of the first elevating cross conveyor in the direction of a second elevating cross conveyor on a second side of the storage assembly onto a storage cross conveyor, wherein the elongated piece good is conveyed by means of the storage cross conveyor in the direction of the second elevating cross conveyor and in the direction of the first elevating cross conveyor. The aforementioned advantages and advantageous effects can be achieved in a simple and cost-effective way with this method, wherein the storage assembly can be especially operated in an at least partly automated manner, especially fully automated manner, by means of the method. The invention also relates to a storage assembly for elongated piece goods, especially made of wood, with a first elevating cross conveyor being arranged on a first side of the storage assembly and a second elevating cross conveyor on the second side of the storage assembly, and at least two storage levels are arranged between the first elevating cross conveyor and the second elevating cross conveyor, with each of the storage levels including at least one storage cross conveyor, and with the storage cross conveyor being provided for conveying the elongated piece good between the first elevating cross conveyor and the second elevating cross conveyor, wherein the storage cross conveyor is arranged for conveying the elongated piece good both in the direction of the second elevating cross conveyor and in the direction of the first elevating cross conveyor.

3 It is therefore an object of the invention to provide a storage assembly, with which the mentioned disadvantages can be avoided, with which the storage and removal of the elongated piece goods can occur in a simple, rapid and flexible manner with a low amount of load and with a low amount of likelihood of damage to the piece goods, and which can be adjusted in a simple way to a changed need for storage and/or changed production planning. This is achieved in accordance with the invention by the features of the above-described storage assembly. This leads to the advantage that the elongated piece goods can be conveyed with the elevating cross conveyor in a simple and flexible manner to a predetermined one of the several storage levels. It is advantageous that different storage levels are filled with elongated piece goods and the elongated piece goods can be available for removal from the different storage levels, with the flexibility of the storage assembly being high. As a result, different geometries of elongated piece goods can advantageously be stored in a simple manner in the same storage assembly and/or can be placed into interim storage. Similarly, storage levels can be added to or removed from the storage assembly in a very simple way. As a result, the storage assembly can be adjusted very simply in the storage capacity, with the extensive need for space of the storage assembly and/or the logistic paths not needing to be changed and adjacent machines and/or apparatuses not needing to be moved. It is advantageous that the number of storage levels and/or the distance between the storage levels can be chosen at will. This leads to the advantage that the storage assembly can have a high storage capacity and a high degree of space utilization. This leads to the advantage that the elongated piece good can be conveyed by transverse transport during the conveyance into the storage assembly, during the conveyance in the storage assembly and during the conveyance out of the storage assembly. It is advantageous that the likelihood of damage to the elongated piece goods can thus be low. It is also advantageous in the storage assembly that the logistic paths of the elongated piece goods can be optimized and that the logistic paths can remain the same even in the case of a changeable size of the storage assembly. It is also advantageous that the logistic paths can be automated. This leads to the advantage that the storage assembly can be automated.

3a This leads to the advantage that the storage assembly is suitable as a process buffer and/or as an intermediate storage assembly, with the storage levels also being known as storeys and the storage assembly also being known as a multi-level storage assembly. The invention will be explained in closer detail by reference to the enclosed drawing, which is Fig. 1, in which merely one preferred embodiment is show by way of example. Fig. 1 shows a front schematic view of a storage assembly 10 for elongated piece goods 5, especially made of wood, in which it is provided that a first elevating cross conveyor 1 is arranged on a first side 11 of the storage assembly 10 and a second elevating cross conveyor 2 is arranged on the second side 12 of the storage assembly 10, and at least two storage levels 3 are arranged between the first elevating cross conveyor 1 and the second elevating cross conveyor 2, with each of the storage levels 3 comprising at least one storage cross conveyor 4, with the storage cross conveyor 4 being provided for conveying the elongated piece good 5 between the first elevating cross conveyor 1 and the second elevating cross conveyor 2. With the storage assembly 10 as shown in Fig. 1, a method for storing elongated piece goods 5, especially made of wood, can be carried out in an advantageous manner, in which it is provided that the elongated piece good 5 is conveyed into the first elevating cross conveyor 1 on the first side of the storage assembly 10, the first elevating cross conveyor 1 lifts the elongated piece good 5 in a predetermined manner up to one of at least two storage levels 3, and the elongated piece good 5 is conveyed at the predetermined storage level 3 out of the first elevating cross conveyor 1 in the direction of the second elevating cross conveyor 2 on the second side 12 of the storage assembly 10 on the storage cross conveyor 4. It can be especially provided that the elongated piece good 5 is conveyed from the storage cross conveyor 4 in the direction of the second elevating cross conveyor 2 into the second elevating cross conveyor 2 and out of the second elevating cross conveyor 2. The storage assembly 10 and the method provide the advantages and advantageous effects as mentioned initially. It is also advantageous that the elongated piece good can be conveyed at least in a partly automated manner, especially fully automated manner, into the storage assembly 10, in the storage assembly 10 and out of the storage assembly 10.

4 It is further advantageous that the elongated piece good 5 can be conveyed in transverse conveyance at least in certain areas, especially during incoming conveyance from storage assembly 10, during conveyance in the storage assembly 10 and during the outgoing conveyance from the storage assembly 10, which means with a direction of conveyance which is substantially nonnal to the longitudinal extension of the elongated piece good 5. The load on the elongated piece good 5 during conveyance, especially during the entire conveying process, can be kept at a low level. Since the elongated piece goods 5 can be stored in several storage levels 3, several types of wood, especially types with different dimensions or types of wood, can be divided among the several storage levels 3, wherein each storage level 3 can be filled with the same type of wood. The storage assembly 10 can thus be filled in a flexible way. Since the elongated piece goods 5 can be taken from several storage levels 3, this leads to the advantage that production can be adjusted in a flexible manner, random conveying sequences of different geometries of elongated piece goods 5 can be composed and the elongated piece goods 5 can be removed from the storage assembly 10 in a predeterminable order, e.g. in a sorting of the same type. This predeterminable order can be changed simply and rapidly. It is thus possible to react quickly to influences on production planning. The order runtime and especially the response time from a change in production planning to processing the production planning can thus be reduced. Predetermined sequences of geometry of several elongated piece goods 5 can thus be composed, with the elongated piece goods 5 being conveyed in a predetermined ordered sequence of their geometry to a subsequent processing step. As a result, a further sorting before or during processing step following the storage assembly 10 can be avoided, through which process steps following the storage assembly 10 can be accelerated. As a result, the storage assembly 10 is thus especially suitable as a process buffer, an interim storage assembly, a processing step storage assembly and/or an interim processing step storage assembly. The storage assembly 10 can also be designated as a multi-level storage assembly because the elongated piece goods 5 can be stored on several storage levels 3. Fig. 1 shows the storage assembly 10 of the first preferred embodiment, with the storage assembly 10 comprising four storage levels 3 and with each of the storage levels 3 comprising 5 at least one storage cross conveyor 4 and/or with each of the storage levels 3 being arranged by at least one storage cross conveyor 4. The storage levels 3 can be arranged advantageously as a storage level module. A storage level 3 can be added to or removed from the storage assembly 10 in an especially simple manner. Depending on the required flexibility, the number of simultaneously conveyed different geometries of the elongated piece goods 5, the required buffer time and/or the required storage capacity, the storage assembly 10 can also be arranged with two, three, five, six, seven, eight and/or even more storage levels 3 instead of the four storage levels 3. The elongated piece good 5 is preferably made of wood, especially as a wooden board, wooden beam, wooden strip and/or wooden slat. Similarly, several wooden boards, wooden beams, wooden strips and/or wooden slats can be joined into an elongated piece good 5, especially glued and/or screwed together. The elongated piece good 5 can further also be made from a composite wood material. The elongated piece good 5 is conveyed by means of a feeding device 14, especially by means of transverse conveyance, to the first elevating cross conveyor I in the direction of incoming feed 141. The incoming transport can thus occur in a simple manner for the elongated piece good 5 and with a low amount of loading on the same. The feeding device 14 can advantageously comprise a blocking device 34, especially a barrier and/or a beam, which can block the elongated piece good 5 at a predeterminable distance from the first elevating cross conveyor I in the direction of conveyance, and in this case especially in the direction of incoming feed 141. It can thus be ensured that always merely one elongated piece good 5 is conveyed into the area of engagement of a first support element 18 of the first elevating cross conveyor I and/or the elongated piece good 5 is conveyed at the right time to the first support element 18. Once the elongated piece good 5 has been conveyed to the first elevating cross conveyor 1, the first support element 18 can grasp the elongated piece good 5 and lift the same. The first elevating cross conveyor I advantageously comprises a plurality of the first support elements 18, which can especially be arranged at a regular distance from one another, with the distances between two each of the first support elements 18 being constant and being arranged in a substantially similar manner, as is shown in Fig. 1. As a result, an even throughput and even conveying speed of the first elevating cross conveyor I can thus be ensured.

6 Advantageously, the first elevating cross conveyor 1 can be arranged as a paternoster cross conveyor 13 and it can be provided that the elongated piece good 5 is conveyed into the first elevating cross conveyor 1 which is arranged as a paternoster cross conveyor 13. The elevating conveyance of the elongated piece good 5 can occur in a manner that is simple, protects the piece good, saves space and/or is automated. Several elongated piece goods 5 can be lifted simultaneously. The first elevating cross conveyor 1 comprises at least one ejector element which removes, pushes out and/or ejects the elongated piece good 5 from the elevating cross conveyor I at a predetermined storage level 3 of the several ones thereof. In accordance with the first preferred embodiment of the storage assembly 10 as shown in Fig. 1, several ejector elements are provided, preferably arranged as push-out members 33, with each storage level 3 being associated with precisely one ejector element, especially one push-out member 33. Once the elongated piece good 5 has been lifted to the level of the predetermined storage level 3, the ejector element associated with storage level 3 can push and/or slide the elongated piece good 5 out of the first elevating cross conveyor I in the direction of the storage cross conveyor 4 and the second elevating cross conveyor 2, especially push it out of the elevating cross conveyor 1. As is shown in Fig. 1, it can be provided in an advantageous further development that a layer forming cross conveyor 6 is arranged between the storage cross conveyor 4 and the first elevating cross conveyor 1, with it being provided that the elongated piece good 5 being conveyed to a layer-forming cross conveyor 6 after being conveyed out of the first elevating cross conveyor 1 and before the conveyance to the storage cross conveyor 4. Said layer forming cross conveyor 6 forms a layer of a predeterminable number of several elongated piece goods 5 in such a way that the several piece goods 5 will rest adjacent to one another and a layer 52 of piece goods is thus formed. As a result of the ability to predetermine the number of the elongated piece goods 5 per layer 52 of piece goods, the forces involved in forming the layers can be kept low, through which the likelihood of damage and/or the likelihood of the uncontrolled sliding of the elongated piece goods 5 over one another can be low. In particular, the layer 52 of piece goods can be arranged in a simple and reliable way even in the case of strongly warped elongated piece goods 5 and in the case of elongated piece goods 5 with strongly varying warping. Once the complete layer 52 of piece goods has been formed, it can be conveyed in cross conveyance and in a layer-forming conveying direction 61 facing in the direction of the 7 second elevating cross conveyor I towards the storage cross conveyor 4, with two adjacent layers 52 of piece goods being positioned at a distance from one another in the storage assembly 10. It is advantageous that damage to the elongated piece goods 5 can be avoided. The storage cross conveyor 4 is used for storing, buffering, warehousing and/or intermediately storing and cross conveying the elongated piece good 5 from the first elevating cross conveyor 1 to the second elevating cross conveyor 2, with the storage cross conveyor 4 being capable of storing and conveying a plurality of layers 52 of piece goods and a plurality of elongated piece goods 5. The elongated piece good 5 which is conveyed from the storage cross conveyor 4 to the second elevating cross conveyor 2 can be received and lowered by a second support element 28 which is comprised by the second elevating cross conveyor 2. The second elevating cross conveyor 2 preferably comprises a plurality of second support elements 28 which are arranged at regular intervals in relation to one another, with the distances between two each of the second support elements 28 being constant and arranged substantially equal to one another, as is shown in Fig. 1. The even throughput and the even conveying speed of the second elevating cross conveyor 2 can thus be ensured. The second support elements 28 can preferably be arranged as pockets, with the elongated piece good 5 being capable of "slipping" into the second support element 28 during the conveyance to the second elevating cross conveyor 2. This enables the simple and reliable conveyance of the elongated piece good 5 in the second elevating cross conveyor 2. It can especially be provided that the first elevating cross conveyor I comprises a plurality of first support element 18 and the second elevating cross conveyor 2 a plurality of second support elements 28. The second elevating cross conveyor 2 can advantageously be arranged as a paternoster cross conveyor 13, and it can be provided that the elongated piece good is conveyed into the second elevating cross conveyor 2 which is arranged as a paternoster cross conveyor 13. The lowering conveyance of the elongated piece good 5 can occur in a manner that is simple, protects the piece good, saves space and/or automated. Several piece goods 5 can be lowered simultaneously. During the lowering, the elongated piece good 5 is conveyed in the direction of an output device 15. Once the elongated piece good 5 comes into contact with the output device 15, the 8 elongated piece good 5 can be output from the storage assembly 10 by means of the output device 15 and can be supplied to a further processing step by being conveyed in the direction towards an output direction 151. It is provided in all conveying steps according to the preferred first embodiment of the storage assembly 10 as shown in Fig. 1 that the elongated piece good is conveyed in the transverse direction. The storage assembly 10 can also be referred to in this context as a cross conveying storage assembly because all conveyances of the elongated piece good 5 in the storage assembly 10 can occur substantially in transverse transport. It is advantageous in this respect that the transverse transport can ensure a merely low force load and a merely low likelihood of damage to the elongated piece good 5 and the transverse transport, especially during lifting and lowering, of the elongated piece good 5 requires a merely low amount of space and can be performed especially free from any reversing. As a result, the logistic paths and/or the conveying paths of the elongated piece good 5 can be optimized and/or can occur with a low amount of effort, especially in an automated way. It can be provided in an advantageous further development that a separating cross conveyor 7 for receiving several piece goods 5 and individual delivery to the second elevating cross conveyor 2 is arranged between the storage cross conveyor 4 and the second elevating cross conveyor 2. It is provided that the elongated piece good 5 is conveyed to the separating cross conveyor 7 after the conveying from the storage cross conveyor 4 and before the conveying into the second elevating cross conveyor 2. The separate transfer of one of the elongated piece goods 5 from the storage level 3 to the second elevating cross conveyor 2 can be ensured. It can preferably be provided in this context that the separating cross conveyor 7 comprises at least one blocking device 34, especially a barrier and/or a beam, which can block the elongated piece good 5 at a predeterminable distance from the first elevating cross conveyor 1 in the direction of conveyance, and in this case especially in the direction 71 of the separating cross conveyor. The elongated piece good 5 which is conveyed by means of the separating cross conveyor 7 can be blocked in the direction of the separating cross conveyor by means of the blocking device 34. The arranged and reliable conveyance from the separating cross conveyor 7 to the second elevating cross conveyor 2 can thus occur. It can further be provided in this context that the separating cross conveyor 7 comprises a lifting apparatus 35 for lifting the elongated piece good 5 from the separating cross conveyor 7. As a result, the elongated piece good 5 can be lifted by a conveying element 32 of the 9 separating cross conveyor 7. The conveying element 32 can be moved further continuously without any contact to the elongated piece good 5. The elongated piece good 5 which is conveyed by means of the separating cross conveyor 7 can be lifted off the conveying element 32 of the separating cross conveyor 7 by means of the lifting device 35. It is advantageous that grinding marks on and/or damage to the elongated piece good 5 can be prevented. It can advantageously be provided that the storage cross conveyor 4, the separating cross conveyor 7 and the layer-forming cross conveyor 6 comprise at least two revolving conveying elements 32, especially conveyor chains or conveyor belts. The transverse transport of the elongated piece good 5 in the entire area of the storage assembly 10 can occur in a simple and flexible way. A good and reliable support of the elongated piece good 5 on the respective conveying elements 32 can be ensured. In particular, the conveying elements 32 of the layer-forming cross conveyor 6, the separating cross conveyor 7 and/or the storage cross conveyor 4 can be arranged in a substantially parallel manner, so that the support of the elongated piece good 5 can occur in an especially reliable manner. Preferably, the storage cross conveyor 4 can transfer a complete piece good layer 52 to the separating cross conveyor 7, with the separating cross conveyor 7 performing the separation of the piece goods 5 of the complete piece good layer 52, especially by means of the blocking device 34. The storage cross conveyor 4 can preferably convey the elongated piece good 5 both in the direction of the second elevating cross conveyor 2 and in the direction of the first elevating cross conveyor 1. The conveying of the elongated piece good 5 in the region of the storage cross conveyor 4 can be arranged in the forward and backward direction 51 and/or at different conveying speeds, i.e. with variable conveying speed. As a result, a first piece good layer 52 can be conveyed to the separating cross conveyor 7 and a second piece good layer 52 which following the first piece good layer 52 can be conveyed back in the direction of the first elevating cross conveyor 1, and a thereafter a third piece good layer 52 is conveyed to the storage cross conveyor 4 without any excessive distance, especially with a predetermined normal distance between two piece good layers 52. It can be provided alternatively that one or several elongated piece goods 5 are taken from the piece good layer 52 and thereafter the remaining piece good layer 52 is conveyed back in the 10 direction of the first elevating cross conveyor 1 and further elongated piece goods 5 are added to the remaining piece good layer 52. The high flexibility of the storage assembly 10 can thus be ensured. It can be ensured that there will not be any large intermediate spaces and large empty storage spaces between two piece good layers 52. This simultaneously allows for the high utilization, high flexibility and/or quick response times of the storage assembly 10, especially also in the case of short term changes in production planning. It can be provided in an advantageous further development of the storage cross conveyor 4 that the storage cross conveyor 4 comprises several storage belt units, with the storage belt units being arranged in a substantially successive manner in the direction of conveyance of the elongated piece good 5. The storage cross conveyor 4 can thus be provided with variable length. The length of the storage cross conveyor 4, which is measured parallel to the direction of conveyance of the elongated piece good 5, can be changed in a simple and flexible way and the storage belt units can be especially arranged in a modular manner, so that the storage cross conveyor 4 can be arranged in a modular and cost-effective way. It can be provided advantageously in this context that the conveying speed and/or the direction of conveyance of the storage cross conveyor 4, the layer-forming cross conveyor 6 and the separating cross conveyor 7 is controlled independent from one another. An especially high flexibility of the storage assembly 10 can thus be ensured. It can advantageously be provided that the direction of conveyance is provided merely in the direction of the second elevating cross conveyor 2 in the region of the layer-forming cross conveyor 6 and in the region of the separating cross conveyor 7. As a result, the layer-forming cross conveyor 6 and the separating cross conveyor 7 can be driven with a drive that drives merely in one direction, through which the drive can be arranged in a simple and cost effective way. Similarly, a common drive can thus be provided for the layer-forming cross conveyor 6 and the separating cross conveyor 7, through which the drive of the storage assembly 10 can be arranged in an especially simple and cost-effective way. In the case of a preferred further embodiment of the storage assembly 1 (not shown), the first elevating cross conveyor I and/or the second elevating cross conveyor 2 can be arranged inclined about a predetermined angle in relation to the perpendicular, especially between 100 and 50', preferably between 20' and 400, with the elongated piece good 5 being lifted 11 inclined in relation to the perpendicular, or is lowered inclined in relation to the perpendicular. As a result, one length of the storage assembly, which is the length between the first elevating cross conveyor I and the second elevating cross conveyor 2, can increase with the height of the storage assembly level 3 and the storage capacity of the storage assembly 10 can be increased. In a further advantageous embodiment of the storage assembly 1 (not shown), the storage assembly 1 can be arranged as a deep storage assembly, with the storage levels being arranged in the depth instead of the height, which means from the top to bottom as seen in the useful position of the storage assembly 10, and with the first elevating cross conveyor I lowering the elongated piece good 5 and the second elevating cross conveyor 2 lifting the elongated piece good 5. As is provided in the first preferred embodiment, the first elevating cross conveyor 1 and/or the second elevating cross conveyor 2 can preferably comprise at least two revolving conveying elements 32, especially conveyor chains or conveyor belts. The first elevating cross conveyor 1 and/or the second elevating cross conveyor 2 can be arranged in a simple way and especially flexible in the height extension. The revolving conveying elements 32 can be supported especially by rollers 31, through which the support and the drive of the conveying elements 32 can occur in an especially simple, cost-effective and reliable manner. Further embodiments in accordance with the invention merely comprise some of the described features. Every combination of features and especially of different described embodiments can be provided.
