Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of logistics equipment, and particularly relates to a lifting machine with a positioning function and a warehouse system. BACKGROUND

[0002] In the logistics field, the lifting machine is one of common devices of the warehouse system. The lifting machine is arranged in a goods shelf and is used for transferring goods between the goods shelf and the ground.

[0003] In the related art, the lifting machine comprises a belt lifting assembly and a loading table. The loading table is used for placing goods. The belt of the belt lifting assembly is connected with the loading table. A driving motor of the belt lifting assembly drives the belt to move through a belt pulley, so as to control the loading table to ascend and descend, thereby lifting the goods on the loading table to a specified layer of the goods shelf. The existing mode is to detect the position of the loading table by arranging a photoelectric switch sensor. However, the photoelectric switch can only detect whether the position of the loading table is aligned, and cannot obtain the specific difference from the specified position.

[0004] Firstly, in the initial installation and debugging stage, problems are prone to occur. When the photoelectric switch sensor alarms, the installer needs to climb up the goods shelf to troubleshoot the problem, which requires a large amount of manpower and cost.

[0005] Moreover, after the lifting machine is used for a period of time, the belt is prone to stretch due to aging. At this time, the belt cannot lift the loading table to the specified height of the goods shelf after the driving motor rotates for a predetermined time, so that the loading table cannot reach the standard height of the specified layer of the goods shelf, and further, the goods cannot be transferred between the loading table and the goods shelf. If the problem that the loading table cannot reach the specified height of the goods shelf cannot be found in time, a safety accident of falling or jamming of the goods from a high place is prone to occur. INVENTION CONTENTS

[0006] The present application provides a lifting machine with a positioning function and a warehouse system, which are used to safely lift goods to a specified height.

[0007] In a first aspect, the present application provides a lifting machine with a positioning function, comprising:

[0008] a support assembly arranged on the ground;

[0009] a lifting driving assembly arranged on the support assembly;

[0010] a loading table driven by the lifting driving assembly to ascend and descend along the support assembly;

The positioning image comprises a detection image corresponding to a detection mark. The detection mark is arranged on the goods shelf.

[0012] The controller determines whether the object table is working normally according to a distance difference between the center position of the detection image and the center position of the positioning image.

[0013] In an implementation, the image acquisition component is arranged on a side of the object table facing the shelf.

[0014] In an implementation, the image acquisition component is a camera capable of acquiring a static image.

[0015] In an implementation, the detection mark is a two-dimensional code or a regular pattern with a geometric center.

[0016] In an implementation, each shelf of the shelf is provided with a detection mark.

[0017] In an implementation, the support assembly is a frame structure.

[0018] Alternatively, the support assembly includes a stand column, and the stand column is provided with one or two stand columns connected to the cross beam of the shelf.

[0019] In an implementation, the lifting driving assembly is configured as one of a synchronous belt lifting structure, a chain lifting structure, or a steel wire rope lifting mechanism.

[0020] In an implementation, the support assembly includes a guide mechanism, and the lifting driving assembly includes at least one set of lifting driving motors arranged at the top of the shelf and connected to the object table through a winding belt.

[0023] In a first aspect, the embodiments of the present application provide a lifting machine with positioning function, comprising a support assembly, a lifting driving assembly, a loading platform and an image acquisition component. The support assembly is arranged on the ground.

The image acquisition component is arranged on the loading platform. A controller of the lifting machine acquires a positioning image through the image acquisition component. The positioning image includes a detection image corresponding to a detection mark arranged on the shelf. The controller determines whether the loading platform reaches the specified height according to a distance difference between the center position of the detection image and the center position of the positioning image, so as to determine whether the loading platform deviates from the preset height.

During the installation and debugging stage of the equipment, the loading platform can be controlled to move to each shelf for equipment calibration and debugging. During the later use stage, the lifting height of the loading platform can be corrected according to the difference between the loading platform and the corresponding shelf, so as to avoid the influence of belt aging.

[0024] When the center position of the detection image coincides with the center position of the positioning image or is within a reasonable distance range, it indicates that the running state of the loading platform is normal, and the loading platform can be normally docked with the carrier on the shelf.

[0039] In order to enable persons skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by persons skilled in the art without creative labor should fall within the protection scope of the present application.

[0040] ​​In the description of the embodiments of the present application, the terms "first", "second" are only used for descriptive purpose and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise explicitly specified.

[0041] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "fixing" and other terms should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrated; it can be mechanical connection; it can be direct connection, or indirect connection through intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0042] In the present application, unless otherwise explicitly specified and limited, the first feature is "on" or "under" the second feature, which can be direct contact between the first and second features, or indirect contact between the first and second features through intermediate medium. Moreover, the first feature "above", "over" and "on" the second feature can be that the first feature is directly above or obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "under" and "under" the second feature can be that the first feature is directly below or obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0043] In the field of logistics, the elevator is one of the common devices of the warehouse system. The elevator is arranged in the shelf and is used for circulating goods between the shelf and the ground.

[0044] In the related art, the elevator includes a belt lifting assembly and a carrier table for placing goods. The belt of the belt lifting assembly is connected with the carrier table, and the driving motor of the belt lifting assembly drives the belt to move through the belt pulley to control the carrier table to ascend and descend, so as to lift the goods on the carrier table to the designated layer of the shelf. The existing mode is to detect the position of the carrier table by setting the photoelectric switch sensor, but the photoelectric switch can only detect whether the position of the carrier table is aligned, and cannot obtain the specific difference from the specified position.

[0045] Firstly, in the initial installation and debugging stage, problems are prone to occur. When the photoelectric switch sensor alarms, the installer needs to climb up the shelf to troubleshoot the problem, which requires a large amount of manpower and cost.

[0046] Moreover, after the lifting machine is used for a period of time, the belt is prone to stretch due to aging. At this time, the belt cannot lift the loading table to the specified height of the shelf after the driving motor rotates for a predetermined time, resulting in that the loading table cannot reach the standard height of the shelf set layer, and thus the articles cannot be circulated between the loading table and the shelf. If the problem that the loading table cannot reach the specified height of the shelf cannot be found in time, safety accidents such as falling or jamming of articles from a high place are likely to occur.

[0047] To safely lift the articles to the specified height, the application provides a lifting machine with a positioning function and a warehouse system. The schemes provided by the embodiments of the application will be described in detail below in combination with the accompanying drawings.

[0048] Figure 1 is the first schematic view of the lifting machine with the positioning function provided by the first embodiment of the application and the shelf 600. Figure 2 is Figure 1 the second schematic view of the lifting machine in and the shelf 600.

[0049] In the first aspect, referring to Figure 1 and Figure 2 , the application provides a lifting machine with a positioning function, which comprises a support assembly 100, a lifting driving assembly 200, a loading table 300, and an image acquisition component 400. The support assembly 100 is vertically arranged on the ground. The lifting driving assembly 200 is arranged on the support assembly 100. The loading table 300 is slidingly connected with the support assembly 100 and is connected with the lifting driving assembly 200. The lifting driving assembly 200 drives the loading table 300 to ascend and descend along the support assembly 100 so that the loading table 300 reaches the specified layer of the shelf 600. The image acquisition component 400 is arranged on the loading table 300. The image acquisition component 400 is electrically connected with the controller of the lifting machine. The controller acquires a positioning image 800 through the image acquisition component 400.

[0050] The positioning image 800 includes a detection image 700 corresponding to a detection mark 500 arranged on the shelf 600. The controller determines whether the loading table 300 reaches the specified height according to the distance difference between the center position of the detection image 700 and the center position of the positioning image 800, so as to determine whether the loading table 300 deviates from the preset height. For example, the detection mark 500 can be arranged on the side of the shelf 600. The image acquisition component 400 is arranged on the side of the loading table 300 facing the detection mark 500. The image acquisition component 400 passes through the detection mark 500 during the ascending and descending process of the loading table 300, and thus acquires the detection image 700 of the detection mark 500.

[0051] The technical scheme of the present application can obtain the difference between the carrier table and the corresponding goods layer. In the equipment installation and debugging stage, the carrier table can be controlled to move to each goods layer for equipment calibration and debugging. In the later use stage, position correction can also be automatically performed to avoid the influence of belt aging.

[0052] When the center position of the detection image 700 coincides with or is within a reasonable distance range of the center position of the positioning image 800, it indicates that the carrier table 300 is in a normal operating state and can normally dock with the carrier on the goods shelf 600. When the center position of the detection image 700 is beyond the reasonable distance range of the center position of the positioning image 800, it indicates that the carrier table 300 cannot normally dock with the carrier on the goods shelf 600. At this time, the elevator alarms and stops, and the staff timely performs maintenance to avoid safety accidents such as falling or jamming of goods due to the failure of the carrier table 300 to normally dock with the carrier. The reasonable distance range can be set according to requirements and is not limited herein.

[0053] It should be noted that the method for the controller to obtain the distance between the center position of the detection image 700 and the center position of the positioning image 800 according to the positioning image 800 is a prior art known to those skilled in the art and is not improved in the present application, and thus will not be described herein.

[0054] In addition, the technical scheme of the present application can obtain the difference between the carrier table 300 and the corresponding goods layer. The difference can be calculated according to the distance difference between the center position of the detection image 700 and the center position of the positioning image 800 and the distance between the image acquisition component 400 and the detection mark 500. The calculation method is a conventional method in the art, and the present application does not involve improvement of the method, and thus will not be described herein.

[0055] In the equipment installation and debugging stage, the carrier table 300 can be controlled to move to each goods layer for equipment calibration and debugging. In the later use stage, the lifting height of the carrier table 300 can also be positionally corrected according to the difference between the carrier table 300 and the corresponding goods layer to avoid the influence of belt aging.

[0056] Each goods shelf 600 has a plurality of goods layers. In some examples, a detection mark 500 is provided on each goods layer of each goods shelf 600 to determine whether the carrier table 300 can reach the preset height each time. In other examples, detection marks 500 are not provided on each goods layer, but only selected parts of the goods layers are provided with detection marks 500. The image acquisition component 400 acquires detection images 700 of the detection marks 500 and compares and judges the detection images 700 with the positioning image 800, so as to determine whether the carrier table 300 needs to be corrected and how to correct it.

[0057] Exemplarily, when the positioning capable lifting machine is a frame type lifting machine, the support assembly 100 is a frame type structure, i.e. a frame type support column. The positioning capable lifting machine can also be a single column lifting machine or a double column lifting machine. The single column lifting machine has one column, and the double column lifting machine has two oppositely arranged columns. The columns are connected to the crossbeam of the shelf 600. In these examples, the lifting driving assembly 200 can be configured as one of a synchronous belt lifting structure, a chain lifting structure and a steel wire rope lifting mechanism, all of which are prior art and not improved by the present application, and will not be described here.

[0058] In addition, in other examples, the positioning capable lifting machine is a winch type lifting machine, the support assembly 100 includes a frame type support column and a guide mechanism, the guide mechanism is vertically arranged on the frame type support column, and the carrier platform is connected with the guide mechanism and is lifted along the frame type support column through the guide mechanism. Exemplarily, the guide mechanism can be configured as a guide rail. In these examples, the lifting driving assembly 200 includes at least one set of lifting driving motor, which is arranged at the top of the shelf (i.e. the top of the frame type support column), and the lifting driving motor is connected with the carrier platform 300 through a winding belt, thereby driving the carrier platform 300 to lift.

[0059] According to the type of the carrier platform 300, the lifting machine can be divided into a layer changing lifting machine and a bin lifting machine. The carrier platform 300 of the layer changing lifting machine is configured as a vehicle carrying platform, which is arranged corresponding to the aisle between two shelves 600 and is used to carry a shuttle vehicle. The carrier platform 300 of the bin lifting machine is configured as a cargo carrying platform, which is arranged corresponding to the shelf 600 and is used to carry a bin.

[0060] Figure 1 The lifting machine in FIG. 1 is a single column lifting machine, which is installed between two shelves 600. In order to show the installation position of the image acquisition component 400 in the lifting machine, Figure 1 only one side of the shelf 600 crossbeam of the lifting machine is shown, and the other side of the shelf 600 is not shown. As shown in FIG. 1, Figure 1 the lifting machine has one column, and the column is vertically installed on the ground. The lifting driving assembly 200 is installed on the column, and the carrier platform 300 is slidably arranged on the column through the guide rail assembly. The lifting driving assembly 200 is configured as a synchronous belt lifting assembly. The driving motor of the synchronous belt lifting assembly is fixedly installed on the column, and the synchronous belt in the synchronous belt lifting assembly is connected with the carrier platform 300 by passing around the top of the column. The driving motor drives the carrier platform 300 to lift along the column through the synchronous belt.

[0061] In this example, the carrier table 300 is configured as a cargo carrying table, which includes a roller conveying assembly for conveying cargo. In other examples, the carrier table 300 can be configured as a vehicle carrying table, which includes a shuttle limiting assembly cooperating with the shuttles to limit the shuttles so as to avoid movement of the shuttles during lifting and facilitate layer changing of the shuttles in the rack 600. The carrier table 300 can be adapted according to the type of the objects to be lifted and transferred. If the objects are cargo or containers, the carrier table 300 is configured as a cargo carrying table. If the objects are shuttles, the carrier table 300 is configured as a vehicle carrying table. It should be noted that the carrier table 300 and the cargo carrying table are prior art and are not improved parts of the present application, and will not be described here.

[0062] For example, the image acquisition component 400 is arranged on the side of the carrier table 300 facing the rack 600. Specifically, as shown in FIGS. 4 and 5, in some examples, the image acquisition component 400 is directly fixedly installed on the side of the carrier table 300 facing the rack 600, and each layer of the rack 600 is fixedly installed with a detection mark 500 on the side thereof. In other examples, the image acquisition component 400 is installed on the carrier table 300 through a fixed support. In these examples, the fixed support is not necessarily fixed on the side of the carrier table 300, but can also be fixed on the top or bottom surface of the carrier table 300, as long as the image acquisition component 400 located on the fixed support faces the rack 600 and can acquire the detection image 700 located on the rack 600. Figure 1 Figure 2 For example, the image acquisition component 400 is configured as a camera capable of acquiring a static image. The detection mark 500 is configured as a two-dimensional code or a regular geometric figure having a geometric center, such as a circle, a rectangle, an equilateral triangle, or an equilateral polygon. It should be noted that the size of the detection mark 500 is smaller than the size of the positioning image 800 acquired by the image acquisition component 400, so as to ensure that the detection image 700 can be located in the positioning image 800. Of course, the size of the detection mark 500 is not limited, and can be selected according to requirements by those skilled in the art.

[0063] In other examples, a plurality of detection marks 500 are arranged at intervals on the side of the column, and each detection mark 500 corresponds to each layer of the rack 600. The image acquisition component 400 on the carrier table 300 faces the column to acquire the image of the detection mark 500 arranged on the side of the column.

[0064] For example, the image acquisition component 400 is configured as a camera capable of acquiring a static image. The detection mark 500 is configured as a two-dimensional code or a regular geometric figure having a geometric center, such as a circle, a rectangle, an equilateral triangle, or an equilateral polygon. It should be noted that the size of the detection mark 500 is smaller than the size of the positioning image 800 acquired by the image acquisition component 400, so as to ensure that the detection image 700 can be located in the positioning image 800. Of course, the size of the detection mark 500 is not limited, and can be selected according to requirements by those skilled in the art.

[0065] In other examples, a plurality of detection marks 500 are arranged at intervals on the side of the column, and each detection mark 500 corresponds to each layer of the rack 600. The image acquisition component 400 on the carrier table 300 faces the column to acquire the image of the detection mark 500 arranged on the side of the column.​

[0066] Figure 3 is a schematic diagram of the positional relationship between the detection image 700 and the positioning image 800 when the object table 300 is in a normal state, provided by an embodiment of the present application; Figure 4 is a schematic diagram of the positional relationship between the detection image 700 and the positioning image 800 when the object table 300 is in an abnormal state, provided by an embodiment of the present application; Figure 5 is a schematic diagram of the positional relationship between the detection image 700 and the positioning image 800 when the object table 300 is in another abnormal state, provided by an embodiment of the present application.

[0067] The image collected by the image collection component 400 is referred to as a positioning image 800, which is an image frame of a certain area. In an ideal state, when the object table 300 is in a normal state, i.e., the lifting driving assembly 200 drives the object table 300 to stop at a preset position, the image collection component 400 collects the positioning image 800, and at this time, the detection image 700 is located at the center of the positioning image 800, i.e., the geometric centers of the detection image 700 and the positioning image 800 coincide, as shown in FIG. 8A. Figure 3 It can be understood that, due to the rotation accuracy of the driving motor and other errors, the geometric centers of the detection image 700 and the positioning image 800 are difficult to completely coincide, and thus, when the distance between the geometric centers is within a reasonable range, it can be considered that the object table 300 has reached the specified position, and it is determined that the object table 300 is in a normal state, can reach the preset height position, and can complete the docking with the carrier on the shelf 600. In some examples, the reasonable range of the distance between the geometric centers of the detection image 700 and the positioning image 800 is 0-10 mm.

[0068] If the lifting driving assembly 200 excessively lifts the object table 300, the height of the object table 300 will exceed the preset position, and at this time, after the image collection component 400 collects the positioning image 800, the detection image 700 will be located in the lower middle part of the positioning image 800, as shown in FIG. 8B. Figure 4 If the lifting driving assembly 200 does not sufficiently lift the object table 300, or because the synchronous belt in the lifting driving assembly 200 is aged and relaxed, the height of the object table 300 will be lower than the preset position, and at this time, after the image collection component 400 collects the positioning image 800, the detection image 700 will be located in the upper middle part of the positioning image 800, as shown in FIG. 8C. Figure 5

[0069] ​The controller determines whether the loading platform 300 is in a normal state according to the distance between the geometric centers of the detection image 700 and the positioning image 800. Specifically, if the distance difference is within a preset reasonable range, it is considered that the loading platform 300 is in a normal state, and the loading platform 300 can complete the docking with the carrier on the shelf 600; if the distance difference exceeds the preset reasonable range, it is considered that the loading platform 300 is in an abnormal state, the elevator stops and alarms, and waits for the staff to repair in time to avoid safety accidents such as falling or jamming of goods due to the failure of the loading platform 300 to dock with the carrier normally.

[0070] In some examples, the image acquisition component 400 has at least two, and the at least two image acquisition components 400 are respectively arranged on both sides of the loading platform 300, and the at least two image acquisition components 400 respectively face the detection mark 500 on the corresponding side to acquire the positioning image 800. Two image acquisition components 400 can respectively acquire the positioning image 800, and the controller obtains two loading platform 300 state determination results according to the positioning images 800 acquired by the two image acquisition components 400, and the two loading platform 300 state results are verified with each other, and if the two loading platform 300 state results are different, it is determined that the loading platform 300 is in an abnormal state. It can be understood that using two image acquisition components 400 to acquire images of the detection marks 500 on both sides to determine the state of the loading platform 300 can avoid the occurrence of loading platform 300 state determination errors caused by errors in image acquisition by a single image acquisition component 400, and greatly improves the accuracy of loading platform 300 state determination.
