Description

Technical Field

[0001] The present invention generally relates to the field of data processing technology. More specifically, the present invention relates to a stacking method of a flat sorting rack used in a panel furniture processing production line. Background Art

[0002] With the continuous development of the custom furniture industry, panel furniture has been favored by more and more consumers, the production scale of enterprises has been continuously expanded, and the production orders undertaken by the production line have also been gradually increasing. Sorting out all the panels of each customer according to the properties of the panels themselves and packaging them quickly and accurately is a process that enterprises need to go through in production. Before packaging, they need to be sorted and stored according to the characteristics of the panels, and then taken out and packaged when they need to be shipped. Therefore, sorting and storage play a very important role in the entire process of enterprise production. Among them, the Chinese patent application document with publication number CN109174658A discloses a panel sorting system and a sorting method thereof, in which the sorted panels are placed in a storage basket. However, since all the panels are placed in the storage basket, it is impossible to clearly know the size of each panel. Therefore, there are certain difficulties in taking out the panels of the required size for packaging or wanting to intuitively know whether the size of the panels in the storage basket is correct.

[0003] In view of the above problems, the prior art adopts a vertical sorting rack. First, panels of different sizes are transported on a conveyor belt, and the robot takes the panels from the conveyor belt and then puts them into storage cells of uniform size in the vertical sorting rack. After the vertical sorting rack is full, the panels are put into the next vertical sorting rack. However, since the storage cells in the vertical sorting rack can only store one panel, if the panel is small, it will lead to waste of storage cell space, which in turn leads to low space utilization of the vertical sorting rack, so more vertical sorting racks need to be obtained to store the panels, which increases the storage cost of the panels. Summary of the invention

[0004] In order to solve the technical problem of low utilization rate of the above-mentioned sorting rack, the present invention provides the following solution.

[0005] The present invention provides a stacking method for a flat sorting rack for a panel furniture processing production line, comprising: obtaining the size of a current panel and the remaining space of an idle layer in the current flat sorting rack, wherein the idle layer includes an occupied layer and an empty layer; sorting the remaining space of the idle layer from small to large; comparing the size of the panel with the remaining space of the sorted idle layer in turn, until the size of the panel is smaller than the remaining space of the current idle layer, and then placing the panel in the current idle layer; if the size of the panel is larger than the remaining space of all the idle layers, placing the panel in the next flat sorting rack or in a temporary storage space; and updating the remaining space of the idle layer of the current flat sorting rack.

[0006] Beneficial effect: By placing the panels reasonably on the flat sorting rack, the space utilization of the flat sorting rack is improved, and it is also convenient to take the panels from the flat sorting rack for packaging.

[0007] Furthermore, when the flat sorting rack is empty, the panels are placed starting from the lowest layer.

[0008] Furthermore, the remaining space of the idle layer is sorted from small to large, including: when the remaining space of the idle layer is smaller than the size of the smallest board among all boards, the remaining space of the idle layer is no longer involved in the sorting.

[0009] Beneficial effect: By eliminating the remaining space of the idle layer that cannot accommodate the smallest board when sorting the remaining space of the idle layer, the number of comparisons between the subsequent board size and the remaining space of the idle layer is reduced, thereby reducing time costs and improving the efficiency of board storage.

[0010] Furthermore, the method further includes: if the remaining spaces of multiple free layers are the same, the remaining spaces of the free layers with the same remaining spaces are sorted from the low layer to the high layer.

[0011] Furthermore, the panel is placed in the next flat sorting rack, including: obtaining the remaining space of the idle layer in the next flat sorting rack; sorting the remaining space of the idle layer from small to large; comparing the size of the panel with the remaining space of the sorted idle layer in turn, until the size of the panel is smaller than the remaining space of the current idle layer, and then the robot places the panel in the current idle layer; if the size of the panel is larger than the remaining space of all idle layers, the panel is placed in the next flat sorting rack.

[0012] Beneficial effect: The storage space of the flat sorting rack is utilized to the maximum extent, thereby improving the space utilization rate of the flat sorting rack.

[0013] Furthermore, a first information code is provided on the panel, and the robot scans the first information code to obtain information of the panel, wherein the information includes a size of the panel.

[0014] Beneficial effect: By setting a first information code for each panel, the robot can quickly obtain the panel size information by scanning the first information code, and then place the panel in the corresponding position in the flat sorting rack according to the panel size information, thereby improving the efficiency of storing the panels and reducing the time cost of storing the panels.

[0015] Furthermore, a second information code is provided on the flat sorting rack, and the robot scans the second information code to obtain information of the flat sorting rack, wherein the information includes remaining space of the free layer.

[0016] Beneficial effect: By setting the second information code, the information of each flat sorting rack can be quickly obtained through the second information code, thereby improving the efficiency of matching the flat sorting rack with the plate size, thereby improving the efficiency of plate storage.

[0017] Furthermore, the plate is rectangular.

[0018] The beneficial effect of the present invention is that the method of the present invention maximizes the use of the remaining space of the idle layer in the flat sorting rack according to the size information of the plate, thereby improving the space utilization rate of the flat sorting rack and reducing the production cost.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0021] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0022] Figure 1 It is a top view schematically showing an application scenario of using a flat sorting rack according to an embodiment of the present invention.

[0023] like Figure 1 As shown, in the production line of panel furniture, a large board will be cut into panels of different sizes, and then transported to the robot's working area via a conveyor belt. The robot will store these panels in a flat sorting rack for storage, and then take them out from the flat sorting rack for packaging when they need to be shipped out of the warehouse.

[0024] In this embodiment, the robot is a manipulator. Specifically, the manipulator can be extended, rotated, etc., and further, the manipulator can take the plate by means of a suction cup. Figure 1 As shown, the manipulator is in the working area ( Figure 1 The corresponding circular area in the figure can be used to store the panels in the corresponding flat sorting racks.

[0025] Figure 2 , Figure 3 and Figure 4 The front view, side view and top view of a flat sorting rack according to an embodiment of the present invention are schematically shown respectively.

[0026] Depend on Figure 2 , Figure 3 and Figure 4 It can be seen that the flat sorting rack has many layers, each layer has the same storage space, and each layer has the same length, width and height. In addition, the flat sorting rack has different specifications, so different batches of panels may be placed on different flat sorting racks.

[0027] Figure 5 FIG. 4 is a flow chart schematically showing a stacking method for a flat sorting rack according to an embodiment of the present invention.

[0028] Specifically, Figure 5 As shown, the stacking method of the flat sorting rack for the panel furniture processing production line of the present invention comprises: S101, obtaining the size of the current plate and the remaining space of the idle layer in the current flat sorting rack.

[0029] In this embodiment, the idle layers include occupied layers and empty layers. Furthermore, a first information code may be set on each panel, and a second information code may be set on each flat sorting rack, so that the size of the panel and the remaining space of the idle layer can be obtained by scanning the first information code and the second information code. Specifically, the robot can obtain the information of the corresponding panel by scanning the first information code, and the information may include the size of the panel, the batch to which it belongs, etc.; at the same time, the robot can obtain the information of the corresponding flat sorting rack by scanning the second information code, and the information may include the number of full layers, the number of idle layers, and the remaining space of each idle layer of the flat sorting rack. The above-mentioned first information code and second information code may be barcodes or QR codes.

[0030] By scanning the first information code of the plate and the second information code of the flat sorting rack, the size of the plate and the usage of each layer of the flat sorting rack can be quickly obtained, thereby improving the efficiency of plate storage.

[0031] In an optional embodiment, under normal circumstances, the robot (i.e., manipulator, whose working area is a circular area) will give priority to storing panels on a flat sorting rack close to the conveyor belt), so it will scan the second information code of the flat sorting rack that is closest to the conveyor belt. When the robot obtains that the number of free layers of the flat sorting rack is 0, the robot will mark the flat sorting rack. The next time the robot stores panels, it will pass over the flat sorting rack and scan the second information code of the next flat sorting rack, i.e., it will no longer store panels in a flat sorting rack without storage space. In other optional embodiments, if the robot is a humanoid robot (the working area is not a circular area, i.e., the distance between the position where the robot takes panels and each flat sorting rack is different), the panels will be stored on the flat sorting rack closest to it first.

[0032] S102, sort the remaining spaces of the free layers from small to large.

[0033] After obtaining the remaining space of each free layer, the robot compares it with the size of the smallest board among all boards in this batch. If there is a free layer with a remaining space smaller than the size of the smallest board, the remaining space of these free layers will no longer participate in the sorting of the above remaining space.

[0034] By eliminating the remaining space of the idle layer that cannot accommodate the smallest board when sorting the remaining space of the idle layer, the number of comparisons between the subsequent board size and the remaining space of the idle layer is reduced, thereby reducing time costs and improving the efficiency of board storage.

[0035] Specifically, the process of comparing the remaining space of the free layer with the size of the minimum board is as follows: first, compare the length of the remaining space of the free layer with the length of the minimum board. If the length of the remaining space of the free layer is smaller than the length of the minimum board, it indicates that the remaining space of the free layer is smaller than the size of the minimum board, that is, the remaining space of the free layer cannot accommodate the minimum board, that is, the free layer is actually a full layer, so there is no need to participate in the sorting of the remaining space of the free layer.

[0036] In addition, if there are multiple idle layers with the same remaining space, when the remaining space of each idle layer is sorted from small to large, the remaining space of these idle layers with the same remaining space will be sorted from low to high, so as to obtain the final sorting of the remaining space of the idle layers of the flat sorting rack.

[0037] In other optional embodiments, the remaining spaces of multiple free layers with the same remaining spaces may be sorted randomly or from a high layer to a low layer.

[0038] Figure 6 It is a top view schematically showing the storage of panels on a certain layer of a flat sorting rack according to an embodiment of the present invention; wherein panel A represents a panel placed vertically, and panel B represents a panel placed horizontally.

[0039] Figure 7 It is a front view schematically showing the storage of panels of a flat sorting rack according to an embodiment of the present invention; wherein, panel 1, panel 2, panel 3, panel 4 and panel 5 respectively represent the first, second, third, fourth and fifth panels placed in the flat sorting rack, and the shaded area of ​​each layer represents the remaining space.

[0040] S103, comparing the size of the panel with the remaining space of the sorted free layers in turn until the size of the panel is smaller than the remaining space of the current free layer, and then placing the panel in the current free layer; if the size of the panel is larger than the remaining space of all free layers, placing the panel in the next flat sorting rack or in a temporary storage space.

[0041] In this embodiment, the plate is rectangular, so the remaining space of the idle layer is also rectangular. In addition, the width of the plate is less than or equal to the width of the flat sorting rack.

[0042] Specifically, Figure 8 is a flow chart according to S103, Figure 8 It can be seen that when the flat sorting rack is empty, the robot places the board on the leftmost position of the lowest layer. In other optional embodiments, it can be placed on any layer, such as the highest layer, or on the rightmost position. Each subsequent board should be placed close to the previous board.

[0043] When the flat sorting rack is not empty, the size of the plate is first compared with the smallest remaining space after sorting; specifically, the length of the plate is compared with the length of the remaining space of the free layer. If the length of the plate is greater than the length of the remaining space of the free layer, it indicates that the size of the plate is greater than the remaining space of the current free layer, and the plate is compared with the remaining space of the next free layer; if the length of the plate is less than the length of the remaining space, the length of the plate is compared with the width of the remaining space of the current free layer. If the length of the plate is greater than the width of the remaining space of the current free layer, it indicates that the plate can only be placed horizontally, that is, the length side of the plate is placed opposite to the length side of the flat sorting rack. You can refer to Figure 6 If the length of the plate is less than the width of the remaining space, it indicates that the plate can be placed in the current free layer horizontally or vertically. In this embodiment, it should be placed in the current free layer vertically, that is, the length side of the plate should face the width side of the flat sorting rack. Figure 6 The reason for placing the plate A in the vertical position is that compared with placing the plate horizontally, placing the plate vertically can maximize the use of the remaining space of the idle layer, thereby improving the space utilization rate of the idle layer, and further improving the utilization rate of the flat sorting rack. It can be understood that when placing the plate when the flat sorting rack is empty, the plate can also be placed horizontally or vertically according to the comparison result of the length of the plate and the width of the flat sorting rack.

[0044] In an optional embodiment, if the panel of the panel furniture is of an irregular shape, such as a triangle, an arc, and a trapezoid (the upper and lower surfaces are flat as a whole), the panel can be considered as a square or rectangular panel, and the side length should be determined according to the actual situation. For example, when the panel is circular, the panel should be considered as a square panel with the diameter of the circle as the side length; when the panel is triangular, the triangular panel can be regarded as a rectangular panel, wherein the longest side of the triangle is the length of the rectangle, and the height of the triangle is the width of the rectangle. When placing a panel that is considered to be a square into a flat sorting rack, it is only necessary to compare the side length of the panel with the length of the remaining space. If the side length of the panel is greater than the length of the current remaining space, it indicates that the panel cannot be placed in the current free layer, and should be compared with the remaining space of the next free layer; if the panel is smaller than the length of the current remaining space, the panel is placed in the current free layer. At this point, the storage of the panels is completed, and you can refer to Figure 7 The result of plate placement on the flat sorting rack is shown.

[0045] If the comparison finds at the end that there is no remaining space in the free layer that meets the size of the panel, it indicates that the current flat sorting rack has no space to store the panel (but the flat sorting rack may be able to store other panels that are smaller than this panel). Then the panel can be placed in the next flat sorting rack or in the temporary storage space.

[0046] Specifically, the process of placing the panel into the next flat sorting rack is as follows: Get the remaining space of the free layer of the next sorting rack; Sort the remaining space of the free layer from small to large; The size of the panel is compared with the remaining space of the sorted free layers in turn until the size of the panel is smaller than the remaining space of the current free layer, and then the panel is placed in the current free layer; if the size of the panel is larger than the remaining space of all free layers, the panel is placed in the next flat sorting rack or in the temporary storage space.

[0047] The specific details are not much different from step S101, step S102, and step S103, so they will not be repeated here.

[0048] By making maximum use of the storage space of the flat sorting rack, the space utilization rate of the flat sorting rack is improved, thereby reducing the occupied flat sorting rack and reducing the cost of plate storage.

[0049] S104: Update the remaining space of the idle layer of the current flat sorting rack.

[0050] The remaining space of the idle layer can be obtained by installing a sensor on the flat sorting rack. For example, a weight sensor can be installed on the flat sorting rack to monitor the weight change of the plate on the idle layer in real time, so as to update the remaining space of the idle layer of the flat sorting rack. In addition, a photoelectric sensor can be installed on the flat sorting rack to monitor the shielding of the plate on the idle layer in real time, so as to update the remaining space of the idle layer of the flat sorting rack. Of course, those skilled in the art can also choose other methods to update the remaining space of the idle layer of the flat sorting rack, such as using image recognition technology.

[0051] In other optional embodiments, the second information code may not be set on the flat sorting rack, and the robot stores the information of each flat sorting rack in its working area, including the remaining space of each free layer in the flat sorting rack, and can communicate with the sensors of each flat sorting rack in its working area. Furthermore, since the robot stores the information of each flat sorting rack, when placing panels, the robot directly matches and stores the panels with the flat sorting rack that is closest to it and has free layers; if the current flat sorting rack does not have enough space to store the panel, it matches and stores it with the next flat sorting rack. After storing the panel, the robot updates the remaining space of the free layer of the flat sorting rack where the panel is placed according to the information fed back by the sensors on the flat sorting rack.

[0052] The present invention reduces the floor space and improves space utilization by using robots to stack panels. In addition, for the storage and stacking of various types of customized rectangular furniture panels that are not in a fixed order and have inconsistent lengths and widths, compared with manual work, the use of artificial intelligence robots to stack panels reduces the storage time, thereby improving the efficiency of storing panels. In addition, by obtaining the size of the panels and matching the remaining space of the free layer in the flat sorting rack, and placing the panels in the flat sorting rack according to the matching results, the storage space of the flat sorting rack can be maximized, thereby reducing the storage cost of the panels.

[0053] In the description of this specification, “plurality” means at least two, such as two, three or more, etc., unless otherwise clearly and specifically defined.

[0054] Although this specification has shown and described a number of embodiments of the present invention, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Those skilled in the art will conceive of many modifications, changes and alternatives without departing from the ideas and spirit of the present invention. It should be understood that in the practice of the present invention, various alternatives to the embodiments of the present invention described herein may be employed.
