[0037] In the related art, the shelf includes multiple columns and multiple beams, which are arranged vertically and staggered to form multiple cargo positions. After the shelf is installed, workers need to inspect and calibrate each cargo position in the shelf in turn to ensure that the surfaces of the beams in the same cargo position are on the same horizontal plane.
[0038] However, due to the large number of cargo spaces and the small space, workers' inspection efficiency of cargo spaces is low.
[0039] In order to solve the above problems, the embodiments of the present application provide a cargo location detection device and a shelf detection system. The solutions provided by the embodiments of the present application will be described in detail below in conjunction with the drawings in the specification.
[0040] Figure 1 It is a schematic diagram of the overall structure of a cargo position detection device according to an embodiment of the present application; Figure 2 yes Figure 1 A top view of the cargo position detection device in FIG. Figure 3 yes Figure 1 A side view of a cargo position detection device in FIG. Figure 4 yes Figure 1 Electrical schematic diagram of the cargo position detection device in FIG.
[0041] Reference Figures 1 to 4 As shown, in a first aspect, an embodiment of the present application provides a cargo position detection device, including a mounting frame 100 , a first distance measuring component 200 and a controller 420 .
[0042] The first distance measuring component 200 is connected to the mounting frame 100, and the first distance measuring component 200 is used to measure the distance between the first distance measuring component 200 and the crossbeam of the shelf. The controller 420 is electrically connected to the first distance measuring component 200, and the controller 420 determines the corresponding cargo position according to the distance value measured by the first distance measuring component 200, that is, determines whether the cargo position meets the standard, which greatly improves the detection efficiency of the cargo position.
[0043] In some examples, there are at least two first distance measuring components 200, each of which is connected to the mounting frame 100, and at least two first distance measuring components 200 are arranged at intervals, and the first distance measuring components 200 are used to measure the distance between the first distance measuring components 200 and the beam of the shelf; the controller 420 is electrically connected to all the first distance measuring components 200, and the controller 420 determines the corresponding cargo position according to the distance values measured by all the first distance measuring components 200. In other words, multiple first distance measuring components 200 can detect multiple distance values. The controller 420 calculates the vertical distance value between the corresponding distance measuring component and the beam according to the distance value measured by each distance measuring component, and then compares and calculates the multiple vertical distance values obtained, and finally determines whether the cargo position is tilted, twisted, etc.
[0044] In some examples, the first distance measuring component 200 is arranged on the mounting frame 100 in the vertical direction, and the first distance measuring signal 220 emitted by it is vertically directed toward the crossbeam, then the measurement value of the first distance measuring component 200 is the vertical distance value between the first distance measuring component 200 and the crossbeam. In some other examples, the first distance measuring component 200 is tiltedly arranged on the mounting frame 100, and the first distance measuring signal 220 emitted by it is tilted toward the crossbeam. In this case, the controller 420 calculates the vertical distance value between the first distance measuring component 200 and the crossbeam according to the angle between the first distance measuring signal 220 and the crossbeam, and the measurement value of the first distance measuring component 200. It should be noted that the vertical distance referred to here can be the vertical distance between the first distance measuring component 200 and the upper crossbeam of the cargo position, or the vertical distance between the first distance measuring component 200 and the lower crossbeam of the cargo position. In the embodiment of the present application, the first distance measuring component 200 is connected to the mounting frame 100, and its first distance measuring signal 220 is emitted downward in the vertical direction toward the beam of the cargo position.
[0045] When the cargo position detection device is provided with only one first distance measuring component 200, it can be installed on the cargo fork of the stacker, and the distances between cargo positions at different positions on the cargo position can be detected by moving the cargo fork.
[0046] In addition, in some examples, the cargo position detection device includes at least two first distance measuring components 200, and at least two first distance measuring components 200 are spaced apart in the same straight line direction. For example, the cargo position detection device includes two first distance measuring components 200, and the two first distance measuring components 200 are spaced apart along the width direction of the cargo position. Generally, two beams are set in each cargo position, and the two ends of the beams are installed on the columns. When the two beams need to be detected, the two first distance measuring components 200 can be set along the width direction of the cargo position. By controlling the length of the fork extended in sequence, the distance value at both ends of each beam can be tested in sequence. Compared with the test method of testing only one position of the beam, if there is an installation measure at one end of the beam, the difference is larger, easier to detect, and the test is more accurate. The controller 420 obtains two vertical distance values according to the values measured by the two first distance measuring components 200, and then compares the two vertical distance values with the set value. If the difference is less than the set range, it is determined that the cargo position meets the requirements. If the difference is greater than the standard, it is determined that the cargo position does not meet the requirements and needs further maintenance.
[0047] Exemplarily, the cargo position detection device includes three first distance measuring components 200, and any two first distance measuring components 200 are located on the same straight line. This arrangement is suitable for the scenario where the bottom of the cargo position is a support surface. Since three points can determine a plane, three first distance measuring components 200 are provided in this embodiment. The embodiment of the present application utilizes three first distance measuring components 200 to measure the distance between each of them and the cargo position beam, and then determines whether the bottom surface of the corresponding cargo position is located on the same plane, thereby determining the state of the cargo position. Figures 1 to 3 As shown, exemplarily, the cargo position detection device includes four first distance measuring components 200, and the four first distance measuring components 200 respectively measure the two ends of the two beams, that is, after the forks of the stacker are fully extended into place, the distance between the two beams can be measured at one time.
[0048] Reference Figures 1 to 3 As shown, the mounting frame 100 is used to provide a mounting position for other components. Exemplarily, the mounting frame 100 may be a frame-type structure design, including a first rod 110 and a second rod 120. The first rod 110 and the second rod 120 are fixedly connected and perpendicular to each other. Figure 1 As shown, in some examples, the mounting frame 100 includes a first rod 110 and two second rods 120, one end of the first rod 110 is fixedly connected to the middle position of one of the second rods 120, and the other end of the first rod 110 is fixedly connected to the middle position of another second rod 120. The first rod 110 and the two second rods 120 form an I-shaped structure. In order to improve the stability of the connection between the first rod 110 and the second rod 120, a diagonal brace 130 is provided at the connection between the first rod 110 and the second rod 120. In addition, illustratively, the first rod 110, the second rod 120 and the diagonal brace 130 can all be lightweight profiles.
[0049] An electrical box 400 is fixedly provided on the first rod 110, and a power supply, a controller 420 and a wireless module 430 are fixedly provided in the electrical box 400. The power supply is electrically connected to the first distance measuring component 200, the controller 420 and the wireless module 430 respectively, and the power supply is used to supply power to the first distance measuring component 200, the controller 420 and the wireless module 430. The controller 420 is used to control and receive the distance between the first distance measuring component 200 and the beam; the wireless module 430 is used to send the data or signal processed by the controller 420 to the host computer. Exemplarily, the power supply can be configured as a battery 410, which is electrically connected to the charging module 440.
[0050] The first distance measuring assembly 200 is connected to the second rod 120. Specifically, the first distance measuring assembly 200 can be fixedly mounted on the second rod 120, or can be movably arranged on the second rod 120. It can be understood that when the first distance measuring assembly 200 is movably arranged on the second rod 120, the measuring position of the beam can be changed by the position of the first distance measuring assembly 200 on the second rod 120.
[0051] In addition, in order to ensure the accuracy of the distance measured by the first distance measuring component 200, the first distance measuring component 200 includes a plurality of first distance measuring modules 210, all of which are fixed in parallel on the module mounting seat 600, and the module mounting seat 600 is connected to the mounting frame 100. In addition, each first distance measuring module 210 is electrically connected to the controller 420, and the controller 420 controls the first distance measuring module 210 to send a first distance measuring signal 220 to measure the distance. If the distance difference measured by all the first distance measuring modules 210 meets the requirements, the controller 420 determines the vertical distance value of the position according to the average value of the distance values measured by all the first distance measuring modules 210; if the distance value measured by one of the first distance measuring modules 210 is significantly different from the distance values measured by the other first distance measuring modules 210, the distance value is discarded, and the controller 420 determines the vertical distance value of the position according to the average value of the distance values measured by all the other first distance measuring modules 210. Measurement errors caused by the inability of a single distance measuring module to receive a reflected signal can be avoided.
[0052] In addition, the first distance measuring module 210 can be configured as a laser distance measuring sensor, a laser range finder, an ultrasonic distance measuring sensor or a visual sensor, which is not limited to any specific method, as long as it can measure the distance between the remaining shelf beams. The controller 420 can be configured as a PLC control module.
[0053] Continue to refer to Figures 1 to 3 As shown, in some examples, the cargo position detection device further includes a second distance measuring component 300, the second distance measuring component 300 is connected to the mounting frame 100, the second distance measuring component 300 is electrically connected to the controller 420, and the second distance measuring component 300 is used to measure the distance between the second distance measuring component 300 and the column of the shelf, so as to determine whether the horizontal direction of the cargo position meets the installation requirements. In the embodiment of the present application, the second distance measuring component 300 sends a second distance measuring signal 320 to the column of the cargo position in the horizontal direction to measure the distance.
[0054] Referring to the measurement method of the first measurement component 100, the second distance measurement component 300 may be one or more. In addition, illustratively, the second distance measurement component 300 includes a second distance measurement module 310. Like the first distance measurement module 210, the second distance measurement module 310 may be fixedly mounted on a module fixing seat, and the second distance measurement module 310 may also be configured as a laser distance measurement sensor, a laser rangefinder, an ultrasonic distance measurement sensor or a visual sensor, without specific limitation.
[0055] Continue to refer to Figures 1 to 3As shown, in order to facilitate the adjustment of the measuring position, that is, to adjust the distance between the two adjacent first distance measuring components 200 and the position of the second distance measuring component 300. The mounting frame 100 also includes a first position adjustment component 140. The first distance measuring component 200 and the second distance measuring component 300 are both fixedly mounted on the first position adjustment component 140, and the first position adjustment component 140 is connected to the mounting frame 100. Through the action of the first position adjustment component 140, the relative position of the first distance measuring component 200 and the second distance measuring component 300 relative to the mounting frame 100 can be changed. Exemplarily, the first position adjustment component 140 includes a sliding member 510 and a locking member (not shown in the figure), the sliding member 510 is slidably connected to the mounting frame 100, the locking member is connected to the sliding member 510 and the mounting frame 100, and the locking member is used to selectively fix the sliding member 510 on the mounting frame 100, and the first distance measuring component 200 and the second distance measuring component 300 are fixedly arranged on the sliding member 510 through the module mounting seat 600. The sliding member 510 can be a slide rail or a profile, and the locking member can be a limit pin or a locking bolt. The operator can use the locking member to adjust the extension length of the sliding member 510 relative to the mounting frame 100 according to actual needs, thereby adjusting the positions of the first distance measuring component 200 and the second distance measuring component 300.
[0056] In the second aspect, the embodiment of the present application provides a shelf detection system, including a stacker and a cargo position detection device of the first aspect, the cargo position detection device is connected to the cargo fork of the stacker, and the stacker places the cargo position detection device in each cargo position of the shelf in turn to detect the condition of the shelf. Compared with the manual measurement method in the prior art, this shelf detection system greatly improves the efficiency of shelf detection and calibration. In addition, since the shelf detection system includes the cargo position detection device in any of the technical solutions in the above schemes, it has all the beneficial effects of the cargo position detection device in any of the technical solutions in the above schemes, which will not be repeated here.
