Description

TECHNICAL FIELD

[0001] The present invention relates to an automated supply method and a mechanical automated warehouse. It belongs to the field of equipment and techniques for the storage and extraction in distribution or production of finished products. It is particularly suitable for the storage and distribution of spare parts or unit products, in particular products sold at a distance, for automatic dispensers, or for the filing of library books and documents. BACKGROUND

[0002] The automated warehouses known in the prior art comprise shelves arranged in parallel, defining storage units identified by a computer system. These shelves extend in height and in length, the storage units being defined by the position occupied by the part of the shelf or drawer used to store the items. The coordinates of each unit of a single shelf can be defined by the height relative to the floor and the distance from the origin associated with the corresponding row. The shelves are generally arranged in pairs back to back. These different rows are regularly spaced from each other to define circulation passages for robotic operators remotely controlled by a computer system. Each of these robotic operators comprises a picking arm that can move in three-dimensional space to be brought to the opposite unit, either to deposit an item to be deposited or to pick it up. These items can be transported with pallets.

[0003] Due to the transverse dimension, the robotic operators are slow, the time scale for depositing or picking up items being too long.

[0004] The known patent applications US2012 / 029687, US2008 / 152466 and patent US 7381022 disclose shelves equipped with mobile carriages, each carriage moving horizontally and vertically upwards to a single conveyor placed above or below the shelf comprising boxes. However, the travel time of each carriage is long, increasing the time to prepare each package. Indeed, only after the completion of the previous package, a new package can be prepared. SUMMARY

[0005] The present invention aims to remedy all or part of these drawbacks.

[0006] To this end, according to a first aspect, the invention relates to a mechanical automated warehouse comprising:

[0007] - at least two horizontal fixed supports for holding in place a plurality of boxes comprising products to be conveyed, each horizontal fixed support at a certain height being referred to as a "fixed support";

[0008] - at least one conveyor configured to support at least one box in horizontal motion, each conveyor being positioned at a conveying height different from the height of each fixed support, at least one conveyor being positioned between two horizontal fixed supports; and

[0009] - At least one movable bracket equipped with a pickup head and a motor for moving the pickup head, the movable bracket being configured to pick up a single box at a box support, move the single box vertically upward to a conveyor height, and mechanically connect the moved box to a conveyor placed at that conveyor height.

[0010] Because of these settings, each box can be picked up and placed on the conveyor very quickly, as the pickup head and the box only make some small movements (basically vertical). Therefore, the warehouse, the subject of this invention, can supply a large number of parts or products per unit time (e.g., per hour).

[0011] In some embodiments, at least one box has a downwardly folded edge forming an opening space on the side facing the pickup head, and the pickup head package has a box support with a folded upper portion configured for accessing the edge of the box.

[0012] Because of these features, a simple movement by the pickup head (including positioning the top over the edge of the box and then lifting it) is sufficient for the box to be picked up by the moving pallet. Therefore, the moving pallet operates exceptionally quickly, and consequently, the warehouse operates exceptionally quickly.

[0013] In some embodiments, at least one box has a downwardly folded edge forming an opening space on the side facing the fixed support, and the fixed support includes a crossbar having a folded upper portion configured for access to the edge of the box.

[0014] Because of these features, simple movement of the box (including positioning the folded edge above a portion of the crossbar of the fixed support and then lowering the box) is sufficient to hold the box in place by the fixed support. This movement is performed by a pickup head carrying the box. Therefore, the operation of the moving tray is particularly fast, and consequently, the operation speed of the warehouse is also particularly fast.

[0015] In some embodiments, the mechanically automated warehouse includes at least two horizontal conveyors and two fixed supports between two consecutive horizontal conveyors, each horizontal conveyor being surrounded above and below by the two fixed supports.

[0016] In this way, each conveyor can be associated with two fixed supports directly above and below it, which limits the travel time for the pickup head to pick up the box and attach it to the conveyor.

[0017] In some embodiments, the mechanically automated warehouse includes a motorized arm located at the end of each conveyor, wherein the conveyor carries each box at the end, and the motorized arm is configured to pick up each box on each conveyor to connect the box to a secondary conveyor.

[0018] Because of these setups, boxes coming out of the warehouse can be packaged or used by operators or machines to produce finished products via a conveyor with fixed supports.

[0019] In some embodiments, the motorized arm rotates each box.

[0020] Because of these configurations, the movement of the robotic arm can be rapid, and the secondary transmitter can be located outside the plane of the transmitter with fixed supports.

[0021] In some embodiments, the mechanically automated warehouse includes means for controlling the path of a movable tray parallel to the plane of a fixed support member to determine the path followed by the movable tray based on the boxes to be retrieved, the path continuously following the different fixed supports carrying the boxes to be retrieved.

[0022] The inventors have determined that this type of path allows for a higher retrieval rate of boxes compared to the path that the mobile tray takes between box pickup locations on different fixed supports.

[0023] In some embodiments, the mobile tray includes means for automatically identifying at least one product present in the box.

[0024] Because of these settings, automated warehouses can directly detect potential mismatches between boxes and the products placed inside them. This reduces the need for manual or third-party retrieving operations after the goods are retrieved from the warehouse, which can complicate error resolution.

[0025] For example, automatic identification can be performed using a camera and / or precise weighing. If a camera is used, processing of the images it provides can include a two-dimensional or three-dimensional indication of the product's position within the container. The pickup device can then use this position to pick up the product.

[0026] In some embodiments, the mobile tray includes a weighing device with higher accuracy per unit weight than the lightest product in the warehouse.

[0027] Therefore, each time a product is removed from the box, an automatic inventory weight check is performed, and the remaining weight of some products and / or products in the box is remembered.

[0028] In some embodiments, the mechanically automated warehouse also includes a conveyor for bringing empty boxes to the empty box storage area.

[0029] Because of these setups, empty boxes can be refilled with products outside of product supply time and returned to fixed supports, for example, via the same conveyors and mobile trays used for product supply.

[0030] For example, products that need to be packaged and shipped are supplied during the day, and the next day's products are supplied at night.

[0031] According to a second aspect, the present invention relates to a method for supplying products present in boxes in a warehouse, the method comprising:

[0032] - At least two horizontal fixed supports are used to hold multiple boxes in place, each of which is referred to as a "fixed support" at a certain height;

[0033] - At least one conveyor configured to support horizontal movement of at least one box, each conveyor positioned at a different conveying height than each fixed support, and at least one conveyor positioned between two horizontal fixed supports; and

[0034] - At least one movable carriage equipped with a pickup head and a motor for moving the pickup head, the method comprising: performed by the movable carriage:

[0035] - Steps for picking up a single box from a box support;

[0036] - The step of moving the picked-up box vertically upwards to the teleportation height; and

[0037] - The steps for establishing a mechanical connection between the conveyor and the box at the designated conveyor height.

[0038] Since the features, advantages, and purposes of this method are similar to those of the repository that is the subject of this invention, they will not be repeated here. Attached Figure Description

[0064] This description is given in a non-limiting manner, wherein each feature of the embodiments may be combined advantageously with any other feature of any other embodiment.

[0065] Notice, Figures 1 to 21 Each one in the diagram is drawn to scale, but different diagrams can be drawn at different scales.

[0066] Throughout the instruction manual, in Figure 1 , 2 In diagrams 4 to 19 and 21, the terms "upper" or "top" refer to the area at or towards the top, corresponding to the normal usage configuration of the warehouse. In these diagrams, the terms "lower" or "bottom" refer to the area at or towards the bottom. The concepts of vertical and horizontal are derived from these definitions. The term "inner" refers to the area near or towards the center of the raised volume defined by the warehouse, while "outer" refers to the area outside or towards the outside of that volume. The term "length" of the warehouse refers to its length along... Figure 1 and Figure 3 The maximum horizontal dimension in the horizontal direction, "width" refers to the distance from the maximum horizontal dimension in the horizontal direction. Figure 2 The minimum horizontal dimension corresponding to the horizontal direction in the diagram. A "front view" is a view where the length of the warehouse is horizontal and the height is vertical. A "side view" is a view where the width of the warehouse is horizontal and the height is vertical. A "top view" is a view where the length of the warehouse is horizontal and the width is vertical.

[0067] Figures 1 to 3A warehouse 20 is shown, which supports and moves open-top boxes 21 containing products. The warehouse 20 has a support structure including columns 22 and longitudinal members 25. A movable bracket 23 translates along the length of the warehouse 20 on the longitudinal members 25, the upper surface 32 of which forms a track. The movable bracket 23 is equipped with wheels 33 (see [reference]). Figure 10 The mobile tray is equipped with a pickup head 39.

[0068] Figure 4 and Figure 5 The diagram shows a horizontal fixed support 28 for the column 22 supporting the box 21 and a horizontal conveyor 27 for conveying the box 21 along the length of the warehouse 20. Preferably, as shown... Figure 4 As shown, each horizontal conveyor 27 is surrounded by two horizontal fixed supports 28. Preferably, as Figure 4 As shown, warehouse 20 includes at least two horizontal conveyors 27. Therefore, preferably, warehouse 20 includes two fixed supports 28 between two consecutive horizontal conveyors 27.

[0069] like Figure 5 and Figure 21 As shown, each horizontal support 28 includes a flat element 47 and a crossbar 26. The flat element 47 is equipped with teeth embedded in vertical slots that form supports in the column 22. The crossbar 26 supported by these elements 47 extends along the entire length of the warehouse.

[0070] like Figure 5 As shown, each box 21 has an edge 42 that folds downwards first on the support and conveyor side and second on the bracket side to form an opening space. On the support and conveyor side, the folded edge 42 holds the box 21 to the fixed support 28 or the conveyor 27 by gravity.

[0071] like Figure 5 and Figure 9 As shown, each horizontal conveyor 27 includes a flat element 29 and a crossbar 30, the flat element 29 being equipped with teeth embedded in vertical slots that form supports in the column 22 (see, in particular, see...). Figures 8 to 9 Crossbars 30, supported by these elements 29, extend along the entire length of the warehouse. Each crossbar 30 supports a vertical plate 31 on which a toothed belt 19 runs. The toothed belt 19, or chain, comprises links that cross the edges of the vertical plate 31. The toothed belt 19 is supported by cables 48 inside the links. Figure 5 Tighten.

[0072] At the end of the conveyor 27, a gear 44 coupled to the output shaft 45 of the rotary motor 43 drives the toothed belt 19. The pad 46, carried by the crossbar 30, guides and slides the box 21 during its movement through the action of the conveyor 27.

[0073] All belts 19 of the conveyors operate in the same direction, such that all boxes 21 carried by the conveyors are brought to the same end of the warehouse 20. In some embodiments not shown, the warehouse 20 includes a motorized arm at this end, configured to pick up each box 21 from each conveyor 27 and connect the box 21 to a secondary conveyor for use by an operator or processing, machining, or assembly machine. For example, due to speed, the motorized arm rotates each box 21 relative to a vertical axis of rotation and may vertically translate it between the conveyors where the box 21 was initially located to the secondary conveyor. In some embodiments not shown, the warehouse 20 also includes a conveyor for bringing empty boxes 21 to an empty box storage area.

[0074] Now refer to Figure 10 , Figure 18 and Figure 19 Describe the movable bracket 23.

[0075] The movable bracket 23 includes a motor 34 mounted on a frame 35 at its upper part. The frame 35 is equipped with wheels 33 that roll on a track 32. The frame 35 supports a column 36 on the side opposite to the box 21 and two columns 37 on one side of the box 21. A box-picking gantry 24 supports a horizontal actuator 38 that moves a pickup head 39, allowing the box-picking gantry 24 to move vertically on the three columns 36 and 37. The pickup head 39 has a vertical rectangular shape, with a thickness less than the width of the folded edge 42 of the box 21, a height substantially equal to the height of the box 21, and a length substantially equal to the length of the box 21. The gantry 24 also includes a support 40 for a camera 41 configured to capture images of the entire contents of the box 21.

[0076] like Figure 10 As shown, in order to move box 21 upward from support 28 to conveyor 27, the rotating frame 24 is first vertically positioned so that the pickup head 39 is completely above the opening of the folded inner edge 42 of box 21. Then, as... Figure 11 As shown, actuator 38 moves pickup head 39, positioning it above the inner edge 42 of the fold. Next, as... Figure 12 As shown, the rotating frame 24 rises, causing the pickup head 39 to engage in the folded inner edge 42, and then... Figure 13 As shown, the folded outer edge 42 of the support member 28, which is opposite to the pickup head 39, is disengaged.

[0077] Then, as Figure 14 As shown, actuator 38 retracts, bringing box 21 closer to rotating frame 24. Then, rotating frame 24 moves vertically (towards) Figure 14 (The bottom of the box or the top when the box 21 must be positioned on the conveyor 27 located above the support 28 that previously supported the box 21).

[0078] If the folded outer edge 42 is not above the toothed belt 19, the actuator 38 is actuated to place it there. The turntable 24 is then lowered, first engaging the folded outer edge 42 of the box 21 in the toothed belt 19, then disengaging the pickup head 39 from the folded inner edge 42. Finally, the actuator 38 retracts. The carrier 23 moves along the length of the warehouse, and the turntable 24 moves along the height of the warehouse, so that the pickup head 39 is aligned with another box 21 to be positioned on the conveyor 27.

[0079] In order to sequence the operation of the various devices in warehouse 20, warehouse 20 includes a device 49 for controlling these devices (see [link]). Figure 1 The control device 49 includes, for example, a computer and / or server for accessing and editing a database of products placed in the various boxes 21. Specifically, the control device 49 determines the route of a moving tray parallel to the plane of the fixed supports based on the boxes to be retrieved. Preferably, the control device 49 determines the path to be followed by the moving tray such that the path runs continuously along the various fixed supports carrying the boxes to be retrieved. For example, if three boxes 21 are to be picked up on the highest fixed support 28 and placed on the highest conveyor 27, and two boxes 21 are to be picked up on a fourth-height fixed support 28 and placed on a second-height conveyor, then the tray 23 first processes the first three boxes on the same support 28, and then processes the last two boxes. Preferably, the path travels sequentially along the supports from top to bottom or from bottom to top. Preferably, the processing device 49 determines the position of all boxes 21 carried by the conveyor 27, and positions the new box 21 on the conveyor 27 only if the trajectory of the new box 21 is unlikely to intersect with the trajectory of the box 21 already present on the conveyor 27.

[0080] like Figure 10 and Figure 18 As shown, the movable tray 23 includes means for automatically identifying at least one product present in the box 21. In the illustrated embodiment, the identification means includes a camera 41 associated with shape, handwriting, and / or code recognition software. Processing of the images provided by the camera 41 may include a two-dimensional or three-dimensional indication of the product's position within the box. A pickup device can then use this position to pick up the product.

[0081] Alternatively or as a supplement, the identification device includes a weighing device (not shown) integrated into the bracket 23, wherein the device has higher accuracy per unit weight than the lightest product in the warehouse.

[0082] Therefore, each time a product is removed from the box, an automatic inventory weight check is performed, and the remaining weight of some products and / or products in the box is remembered.

[0083] like Figure 22 As shown, a second embodiment of a warehouse 50, having elements of the first embodiment 20, is presented as the subject of this invention. The warehouse 50 includes rows of boxes 21 and conveyors on both sides of the movement plane of the rotating frame 51. Figure 23 As shown, compared to the rotating frame 24, the rotating frame 51 has additional degrees of freedom because it rotates about a vertical axis of rotation 52 to pick up boxes 21 on each side of its vertical plane of motion. A motor 53 rotates the pickup head 39. The rotating frame 51 includes a precision balance 54 for verifying the weight of each box 21 and storing the available product inventory within the boxes 21. Preferably, a camera 41 is mounted on the pickup head 39 to rotate with it.

[0084] exist Figure 24 In one embodiment 60, a method for supplying products present in box 21 is shown.

[0085] In step 61, the control device 49 receives the product list to be supplied when the warehouse 20 outputs it.

[0086] In step 62, control device 49 verifies the presence of products in warehouse 20 by accessing a database and determines the location of boxes 21 containing these products. If no products are found in warehouse 20, control device 49 returns a message to the device used for managing inventory and orders.

[0087] In step 63, the control device 49 determines the fastest path between the boxes 21 containing the product to be supplied. When the same product is located in several boxes 21, the control device 49 selects the boxes from these boxes to optimize the supply rate. When the quantity of the same product to be supplied means that at least one box 21 containing such a product must be retrieved, the control device 49 optimizes the selection of boxes based on the supply rate, or maximizes the number of boxes 21 still available in the warehouse 20 after the product is supplied.

[0088] In step 64, the control device 49 controls the positioning of the tray 23 opposite to the next box 21 to be retrieved (see...). Figure 10 ).

[0089] In step 65, the control device 49 controls the raising of the pickup head 39 and the engagement of the pickup head 39 with the folded inner edge 42 of the box 21 (see...). Figure 11 and 12 ).

[0090] In step 66, the control device 49 controls the raising of the pickup head 39, the lifting of the box 21, and the disengagement of its folded outer edge 42 from the support member 28 carrying the box (see [link]). Figure 13 Note that steps 65 and 66 are performed within a single, continuous, and uniform movement of the pickup head 39.

[0091] In step 67, control device 49 controls the pulling of box 21 into the warehouse (see...). Figure 14 ).

[0092] In step 68, the control device 49 uses the camera 41 to check the presence of the product to be supplied that should be located in the box 21, as well as the contents of the box 21 carried by the bracket 23. Optionally, the control device 49 uses a weighing device (not shown) integrated into the bracket 23 to weigh the contents of the box 21 to determine the quantity of product present in the box 21.

[0093] In an optional step 69, the control device 49 estimates the mechanical deformation of the box 21 under the influence of the weight of its contents. This deformation corresponds to the downward movement of the folded outer edge 42 of the box 21.

[0094] Alternatively, particularly if the bracket 42 does not include a weighing device, the control device 49 uses the camera 41 to determine this deformation, for example by adding a pulsed light source (e.g., a light-emitting diode (not shown)) to illuminate only a portion of the image captured by the camera 41, and by determining the position of the reflection of the light emitted by the light source on the edge of the box 21 parallel to the width of the warehouse 20. This includes the edge of the box 21 from the inner folded edge 42 to the outer folded edge 42.

[0095] In step 70, the control device 49 controls the vertical movement of the box 21 until the folded outer edge 42 of the box 21 is at a conveying height slightly above (e.g., one centimeter) the height of the toothed belt 19 of the conveyor 27, which is closest to the support 28 that picks up the box 21.

[0096] In step 71, the control device 49 controls the positioning of the folded outer edge 42 of the box 21 carried by the bracket 23 above the toothed belt 19 of the conveyor 27 (see...). Figure 15 Of course, the vertical motion in step 70 and the horizontal motion in step 71 can be combined in a single continuous trajectory.

[0097] In step 72, the control device 49 controls the descent of the pickup head 39 and the engagement of the folded outer edge 42 of the box 21 with the toothed belt 19 (see...). Figure 16 ).

[0098] In step 73, the control device 49 controls the descent of the pickup head 39 and the disengagement of the inner edge 42 of the box 21 from the pickup head 39 (see [link]). Figure 17 Note that steps 62 and 63 are performed within a single, continuous, and uniform movement of the pickup head.

[0099] In step 74, if the path is not yet complete, return to step 64 for the next box 21 on the path of tray 23. Simultaneously, control device 49 records box 21 and the product retrieved from warehouse 20 in the database.
