Shelf warehouse with a roundabout on a closed guideway
The invention relates to a rack storage for storing articles in storage spaces of shelves, wherein at least one rack aisle is formed between at least two shelves and, wherein first guide tracks are provided substantially in the direction of the shelves and second guide tracks substantially transverse to the shelves on which guide tracks at least one rail vehicle for storage and retrieval of the article controlled by control means is movable.
The patent application WO2014 / 204 300 A1 thus discloses a rack storage with control means for controlling the path a railway vehicle should take when loading and unloading an article. Depending on how dense the traffic of railway vehicles on individual guideways and crossing points of guideways, or is planned by the control means, the control means identify them as "blocked" or for example as "depending on the direction only with a certain speed passable". This is intended to ensure the smoothest possible operation of the railway vehicles on the guideways during storage and retrieval of articles. In this known rack storage, however, has proven to be a disadvantage that the control means are very complex and thus prone to failure and do not reach the necessary for high-performance warehouses throughput.
If articles from a racking warehouse, such as the shelf storage disclosed in WO2014 / 204 300 Al, are outsourced to a picking station, they should be sorted out of the rack storage on the conveyor if possible in order to minimize the need to sort on the conveyor , Flierzu the control means to control the rail vehicles so that the railway vehicles, the articles according to the desired sorting, get successively from the individual storage bins and give a lift to the conveyor technology, whereupon the conveyor system transports the sorted items to the respective order picking. Due to "blocked" guideways, defective rail vehicles or other circumstances, however, there may be occurrences that the items can not be outsourced with the required sorting from the shelf storage. For this reason, a so-called pre-zone must be realized in front of the rack warehouse as part of the conveyor technology, in which, for example, by a circulated conveyor technology sorting of the article is possible before the sorted articles are discharged from the circulated conveyor technology and transported to the respective order picking. However, the lifts of the shelf storage and the sorting in the Vorzone form a bottleneck limiting the bottleneck when retrieving, since the outsourced from the different shelf levels of the shelf warehouse items must all be sorted in the guided in a single circle conveyor.
The invention has for its object to provide a shelf storage and a method for operating such a shelf storage, are avoided in the above disadvantages and as many items stored in a small space, and can be outsourced and picked. According to the invention, this task is achieved in that a self-contained guideway is formed by first guideways and second guideways of a rack level and that a stretch of the closed guideway each from a crossing point of one of the first guideways with one of the second guideways to the next crossing point of the first Guides with one of the second guideways is set and that the control means are designed to control the railway vehicles on the sections of the closed guideway when storing and retrieving the articles in a main direction in the form of a roundabout so that the section of the closed guideway, on the There is more than one railway vehicle, which is used only by rail vehicles in the main direction.
By defining a main direction for driving on the guideways, the advantage has been obtained that the control of the railway vehicles by the control means can be carried out much more efficiently. The summarization of two first and two second guideways of a shelf level to a closed guideway which is driven as a roundabout of the railway vehicles in the main direction gives the advantage that the railway vehicles with relatively high speed and with few braking operations can be controlled, which the wear and Energy consumption reduced. In order to further increase the efficiency and the throughput during the loading and unloading of articles from the shelf storage, certain sections of the track on which no other rail vehicle is currently traveling can also be driven against the main direction. The smallest possible route section here is to be understood as the route section of a guideway between adjacent intersection points with other guideways.
The closed guideway forming the roundabout can in this case be realized completely or partially upstream of the shelves or also on each shelf level in front of the shelves. This results in the advantage that in each shelf level is given a way to sort the outsourced in the respective shelf level article. Only then are the articles sorted per shelf level transferred to the lift and transported downwards. As a result, the advantage is obtained that the outsourced from the shelf warehouse items are delivered sorted by the lift. This makes it possible to provide picking stations directly at the lifts of the rack storage, which is why it is possible to dispense with a classic pre-zone and the corresponding conveyor technology for transporting the articles to the picking stations. This significantly reduces the space required by the picking system and the time required to pick a job. By eliminating the upstream material handling equipment, additional costs can be saved and downtimes of the picking system for repair work on the conveyor system can be reduced. The same advantage as with picking stations is also achieved by the direct connection of article handling stations, goods receiving stations or robotic handling stations to the rack warehouse.
It is also advantageous to set the main direction in the closed guideway in superposed shelf levels opposite each other. This makes it possible for articles to be relocated, for which there is already a renewed need for another picking station, in the course of re-storage, to use the optimum level in terms of distance.
Likewise, rail vehicles can be transported as needed via a railway vehicle lift in a rack level in which just a lot of railway vehicles for storage and retrieval of articles are needed.
These and other advantageous embodiments of the shelf storage according to the invention are explained in more detail below with reference to FIGS.
Figure 1 shows a plan view of a shelf level of a shelf storage, in which the second guideways of the closed guideway are provided on the front side of the shelves. Figure 2 shows an oblique view of the shelf level of the shelf storage according to Figure 1, wherein only a closed guideway is provided.
Figure 3 shows a plan view of a shelf level of a shelf storage, in which the second guideways of the closed guideway are provided on only one end side of the shelves.
FIG. 4 shows an oblique view of three shelving levels of the shelf storage according to FIG. 3.
FIG. 5 shows an oblique view of 12 shelf levels of the shelf storage according to FIG. 3.
Figure 6 shows a plan view of a shelf level of a shelf storage, in which the second guideways of the closed guideway are provided on only one end side of the shelves and are connected via connecting guideways to lifts, where picking stations are arranged.
FIG. 7 shows an oblique view of three shelving levels of the shelf storage according to FIG. 6.
FIG. 8 shows an oblique view of 12 shelving levels of the shelf storage according to FIG. 6.
FIG. 9 shows a further oblique view of 12 shelving levels of the shelf storage according to FIG. 6, wherein a railway vehicle lift is provided.
FIG. 10 shows a plan view of a shelf storage according to a further exemplary embodiment of the invention.
Figure 1 shows a plan view of a shelf level of a shelf storage 1 which has eight shelves 2, of which six shelves 2 are placed together as a double shelf, with four rack aisles 3 are formed. In the shelves 2, a plurality of storage bins 4 are provided for storing articles 5. For storing the article 5 in the shelf storage 1 and for retrieving the article 5 from the shelf storage 1, the shelf storage 1 guided on guideways train vehicles 6, which are controlled by control means not shown in the figures. Railway vehicles 6 guided on guideways are known to the person skilled in the art, for example, from patent application WO2014 / 204,300 A1, for which reason their technical realization is not discussed in detail here.
In the rack aisles 3 of the shelf storage 1 first guideways 7 forming rails for the railway vehicles 6 are provided. At the two end sides of the shelves 2 and thus extending transversely to the shelves 2 second guideways 8 forming rails for the railway vehicles 6 are provided. Via the first guideways 7 and the second guideways 8, a railway vehicle 6 can reach each storage location 4 of the shelf level of the shelf storage 1 in order to pull an article 5 from a storage location 4 onto the railway vehicle 6 or to push it from the railway vehicle 6 into the storage location 4.
The control means form at the shelf storage 1 of two first guideways 7 and two second guideways 8 of the shelf level a self-contained guideway 9 for the storage and retrieval of articles 5 for the railway vehicles 6 a Flauptrichtung Fl is defined as the transport direction, in the Figure is shown by arrows. In the embodiment according to FIG. 1, interlocking closed guide tracks 9 are defined, which define a transport direction for the track vehicles 6 for each rack aisle 3. The control means consequently control railway vehicles 6 in the first place corresponding to these secondary directions through the rack warehouse 1, whereby a structured traffic of the railway vehicles 6 and a high throughput in the storage and retrieval of articles 5 is achieved. On the one hand, several railway vehicles 6 can travel on a guideway simultaneously, on the other hand, the uniform transport direction results in the advantage that it is possible to drive at a higher speed and fewer braking processes.
Of the control means of the shelf storage 1 further sections 10 of the closed guideway 9 are set, each of a crossing point 11, one of the first guideways 7 with one of the second guideways 8, to the next intersection 11, one of the first guideways 7 with one of the second Guideways 8, enough. The control means are now designed to train vehicles 6 on sections 10, on which there is currently no other railway vehicle 6, or for the duration of the passage through a rail vehicle 6 will be to drive against the Flauptrichtung Fl. Flierdurch the advantage is obtained that can be converted in the route planning by the control means according to the Flauptrichtung Fl to be traveled long paths for a railway vehicle 6 in a short path against the Flauptrichtung FI, if just no traffic. Flierdurch the throughput of transported with the railway vehicles 6 Articles 6 can be further increased.
FIG. 2 shows an oblique view of the shelf level of the shelf storage 1 according to FIG. 1. In FIG. 2, however, a different definition of the main direction H by the control means has been carried out by way of example. According to this embodiment of the invention, the main direction H has been set only for the outer rows of shelves 3 and here in the counterclockwise direction. The determination of where stored in the shelf storage 1 and outsourced and where fast-rotating and slow-moving article 5 are stored, can have an influence on the determination of the main direction H.
Figure 3 shows a plan view of a shelf level of a shelf storage 1, in which the second guideways 8 of the closed guideway 9 are arranged on only one end side of the shelves 2. Flierdurch the advantage is obtained that the first guideways 7 each shelf level is preceded by a closed guideway 9, can be controlled from the train vehicles 6 in each of the first guideways 7. From the storage bins 4 of this shelf level outsourced Article 5 can thus be 100% sorted delivered to a lift.
FIG. 4 shows an oblique view of three shelving levels E of the shelf storage 1 according to FIG. 3. The control means control the rail vehicles 6 in closed shelf levels E arranged one above the other in each case in opposite directions Fl. Flierdurch it is possible for re-stored items for which there is already a renewed need for another order picking, in the course of restocking the optimal route in terms of distance to use for new outsourcing.
Figure 5 shows an oblique view of 12 shelf levels E of the shelf storage 1 according to Figure 3. The closed guideways 9 are again arranged on the front side of the shelf storage 1 in extension of the rack aisles 3, wherein the stacked in each other arranged shelf levels E main directions H only by an arrow are indicated.
Figure 6 shows a plan view of a shelf level E of a shelf storage 1, in which the second guideways 8 of the closed guideway 9 are again provided only on one end side of the shelves 3. In the rack storage 1 close to the closed guideway 9 charging bays 17, in which railway vehicles Article 5 on lines 12, or can absorb these, without blocking the flow of railway vehicles on the closed track. Connecting lines 12 are formed by a short conveyor technology and decouple the loading and unloading of the lift movement by there are passed from the railway vehicles 6 from loaded articles 5 to lift platforms 18 of the lifts 13. At the lifts 13 of the shelf storage 1 immediately include picking 14, which have a short conveyor technology as a link 15 to the actual manual picking. As a result, the advantage is obtained that four order picking 14 are arranged directly to the shelf storage 1 and the usual Vorzone can be omitted.
This saves space in the warehouse, allowing more items to be stored on the same warehouse floor.
According to another embodiment, the connecting sections 12 could connect to the closed guideway 9 even without intermediate charging bays 17. Instead of the manual order picking stations, automatic picking stations or robot handling stations operated by robots could also be realized. It could be realized directly at the lifts 13 quite generally article handling places at which certain Flandlungen be performed on the stored or outsourced articles 5. Likewise, goods receipt points for items 5 to be stored could be realized directly at the lifts 13.
FIG. 7 shows an oblique view of three shelf levels E, and FIG. 8 shows an oblique view of 12 shelf levels E of the shelf storage 1 according to FIG. 6. In FIG. 7, only two of the four elevators 13 and order picking stations 14 are provided for better illustration. It is clearly recognizable on what small area of the warehouse the shelf storage 1 can be realized with the possibility of sorting the article 5 in each rack level E and four order picking 14.
FIG. 8 shows an oblique view of 12 shelf levels of the shelf storage according to FIGS. 6 and 7.
Figure 9 shows a further oblique view of 12 shelf levels E of the shelf storage 1 according to Figure 6, wherein in the middle of the longitudinal side of the front shelf 3 symbolically a railway vehicle lift 16 at the end of another arranged in the middle of the shelf storage 1 second guide track 8 is arranged , The lifts 13 are provided for transporting the articles 5 and can not transport rail vehicles 6. If the control means detect an increased demand for rail vehicles 6 in one of the shelf levels E, since there in the next time particularly many items 5 are to be stored or outsourced, then the control means drive train vehicles 6 of shelf level E with less traffic to to drive the railway vehicle lift 16 in the rack level E with heavy traffic. This railway vehicle lift 16 can also serve railway vehicles 6, which need service or are already defective, to drive to a technician station. The railway vehicle lift 16 may transport empty railway vehicles as well as article loaded railway vehicles.
According to a further embodiment of the invention, the lifts 13 could also be designed to transport the railway vehicles 6 together with articles 5. According to a further advantageous embodiment, a guideway running in the closed guideway 9 could be provided in a closed guideway 9, which guideway can be used as an abbreviation in order not to have to drive the entire circle of the closed guideway 9.
The control means of the rack storage 1 work off a method for operating the rack storage 1 for offloading and picking articles 5, wherein the following method steps are carried out:
One of the rail vehicles 6 of the shelf level E, in which an article to be commissioned 5 is stored, is controlled to the storage space 4 in the rack 1, wherein the sections of the closed track 9 are traversed only in the main direction H, in which more than one Railway vehicle 6 is located. Subsequently, the article 5 to be picked is loaded from the storage location 4 onto the railway vehicle 6. The railway vehicle 6 with the article to be commissioned Article 5 of the shelf level E is driven up to the lift 13 or to the connection section 12 so that the sections of the closed track 9 are traversed only in the main direction H, in which more than a railway vehicle 6 is located. The article 5 to be picked is transported with the lift 13 to the picking station 14 and picked there by a picker or robot in a destination container, possibly resulting in residual quantities of the article 5. The return transport of the residual amounts of the article 5 in the rack storage 1 is carried out with the lift 13 and guideways 7 and 8, wherein the sections of the closed guideway 9 are traversed only in the main direction H, in which there is more than one railway vehicle 6. Finally, the article 5 is delivered from the railway vehicle 6 to a storage location 4. By this method, the advantages mentioned above with respect to the shelf storage 1 arise.
FIG. 10 shows a plan view of a shelf storage 1 according to a further exemplary embodiment of the invention, in which eight double shelves 2 are provided. The control means control railway vehicles so that two closed guideways 9 with main directions H arise. This rack storage 1 has the advantage that around the rack storage 1 order picking 14 can be arranged directly on lifts 13, only one example being shown. Also, a railway vehicle lift 16 or other lifts and places, such as a goods receipt point, can be arranged anywhere around the shelf storage 1.
It may be mentioned that the rack storage according to a further embodiment of the invention could also be designed so that rail vehicles are transported with in and outsourced items on the lifts between the rack levels with. This lift trip could also be used to recharge the railway vehicle.
Furthermore, it can be mentioned that as an article in the sense of this description the following articles known to the person skilled in the art are understood: containers with a plurality of identical or different " smaller " Articles (medicament packs or the like); Cardboard (outer carton or original carton) with several identical or different " smaller " Articles (medicament packs or the like); Containers with several subdivisions (compartments), each with several equal or different " smaller " Articles (medicament packs or the like); Tray (loading equipment) with a carton; Tray (load carrier) with several boxes. It should also be noted that the shelf storage can easily have deep or multi-deep storage bins in which several items can be stored behind each other.
Furthermore, it can be mentioned that at the lifts 13, a conveyor system can be connected, which emits the sorted container stream to a shipping ramp, a palletizing robot, a consolidation station or the like.
