Description

Technical Field

[0001] The invention relates to the field of regulating valve production, and in particular to a detection system for the capacity of a three-dimensional storage material frame. Background Art

[0002] Automated high-bay warehouses first appeared in logistics warehousing. With the popularization of various industries, they are now widely used in manufacturing warehousing. The high-rise rationalization of high-rise warehouse equipment, automated access, and simple operation make automated high-bay warehouses a high-level form of warehousing. In the current trend of intelligent production development, automated high-bay warehouses have become an indispensable part of production.

[0003] In existing automated stereoscopic warehouses, the volume of material frames is generally large and can store a variety of materials. However, in actual use, the material volume utilization rate in the material frames is low, resulting in a large waste of the volume of the material frames. How to quickly detect the volume ratio of the material frames and maximize the use of the space of the material frames is an urgent problem that the existing automated stereoscopic warehouses need to solve. Therefore, it is necessary to provide a detection system for the capacity of stereoscopic storage material frames. Summary of the invention

[0004] The purpose of the present invention is to provide a detection system for the capacity of a three-dimensional storage material frame to solve the problem that the volume ratio of the material frame cannot be quickly detected during actual use, resulting in a low volume utilization rate of materials in the material frame.

[0005] In order to solve the above technical problems, the technical means of the detection system of the capacity of the three-dimensional storage material frame adopted by the present invention are as follows: it includes a bottom cover matched with the material frame and a measuring box containing a measuring medium, and the measuring box is fixed above the bottom cover; the bottom cover is provided with a plurality of through holes, and a piston cylinder is installed in each of the through holes, and the protruding end of the piston cylinder is flush with the bottom of the bottom cover; a downwardly telescopic piston rod is provided in the piston cylinder, and a counterweight ball is connected to the lower end of the piston rod, and the counterweight ball makes the piston rod extend to the lowest point in normal state; the upper part of each piston cylinder is also connected to a measuring branch pipe, and the other end of the measuring branch pipe is connected to a measuring main pipe, and the other end of the measuring main pipe is connected to the bottom of the measuring box, and an exhaust pipe is fixed through the top of the measuring box; when the piston rod is extended to the shortest, the measuring medium in the measuring box is at the highest point; when the piston rod is extended to the longest, the measuring medium in the measuring box is at the lowest point.

[0006] The above-mentioned technical scheme has the following technical advantages for detecting the capacity of a three-dimensional storage material frame: the piston rod of the present invention always droops and stretches to its longest point under the action of the counterweight ball, and each piston rod represents the height of the idle space in a certain area of ​​the material frame, that is, it can also represent the volume of the idle area in the area; when the counterweight ball at the lower part of the piston rod contacts the material in the material frame, the piston rod will push the measuring medium in the piston cylinder back into the measuring box; since the volume of the measuring box is equal to the volume of all piston cylinders, the expansion and contraction of all piston rods can be reflected in the liquid level of the measuring box, and the expansion and contraction of each piston rod can be reflected in the liquid level of the measuring box. The length represents the idle height of a certain area, so when the volume being measured is equal to the volume of all piston cylinders, the volumetric ratio of the idle part in the measuring box is the volumetric ratio of the idle space in the material frame, and the idle space volumetric ratio in the material frame is converted into the idle space volumetric ratio in the measuring box. The measuring process is simple and the speed of detecting the volume of the material frame is fast. The present invention indirectly reflects the idle space volumetric ratio of the material frame on the liquid level of the measuring box, which not only enables the idle space volumetric ratio of the material frame that is difficult to measure to be measured, but also has a fast measuring speed and a simple measuring process. The volumetric ratio is measured so that the storage space of the stereoscopic warehouse can be fully utilized later.

[0007] As a preferred solution, the measuring medium is transformer oil; transformer oil has good fluidity, a high ignition point, and is safe and non-flammable.

[0008] As a preferred solution, the body of the measuring box is a cylinder and the measuring box is made of transparent plastic material; the measuring box made of transparent plastic material is convenient for observing the liquid level of the measuring medium in the measuring box so as to obtain the idle volume ratio in the storage warehouse.

[0009] As a preferred solution, the outside of the measuring box is provided with scale values ​​from top to bottom, and the scale values ​​display the percentage of the volume of the measuring medium in the measuring box to the volume of the measuring box in percentage; the scale values ​​facilitate the convenient deriving of the volume ratio of the material frame.

[0010] As a preferred solution, a sealing plug is further provided in the measuring box, which separates the exhaust pipe from the measuring medium in the measuring box; the sealing plug can slide up and down in the measuring box to ensure that the pressure in the measuring box is balanced with the outside when the piston rod is extended and retracted.

[0011] As a preferred solution, the outlet end of the exhaust pipe is connected to an airbag. When the piston rod is extended to the shortest, the airbag is in a positive pressure state. The airbag can play a certain balancing role in the measuring box and its closed pipeline, ensuring that the measuring medium flows normally and smoothly in the piston cylinder, the measuring main pipeline, the measuring branch pipeline and the measuring box sealing plug.

[0012] As a preferred solution, the volume of the airbag is larger than the volume of the measuring box.

[0013] As a preferred solution, a liquid level sensor is further provided in the measuring box, and the liquid level sensor is used to detect the height of the measuring medium in the measuring box; the liquid level sensor can directly collect the measured volume data of the material frame and generate it to the WMS after calculation.

[0014] As a preferred solution, a guide frame is provided at the bottom of the bottom cover, the guide frame is located on the inner side of the material frame, and the cross-section of the guide frame is a triangle or an isosceles trapezoid; the guide frame facilitates the docking of the bottom cover with the upper part of the material frame, thereby improving the efficiency of detection.

[0015] As a preferred solution, a bracket is provided at the upper end of the bottom cover, the measuring box is mounted on the bracket, and the bottom cover is mounted on a multi-axis robotic arm through the bracket; the detection device is more efficient in conjunction with the multi-axis robotic arm.

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] Example 1

[0025] like Figure 1As shown, the detection system of the capacity of the three-dimensional storage material frame includes a bottom cover 2 matched with the material frame 1 and a measuring box 8 filled with a measuring medium, the measuring box 8 is fixed above the bottom cover 2, and the measuring medium 10 is preferably transformer oil; a plurality of through holes are provided on the bottom cover 2, and an inverted piston cylinder 3 is installed in all the through holes, and the extended end of the piston cylinder 3 is flush with the bottom of the bottom cover 2; a piston rod 4 that telescopes downward is provided in the piston cylinder 3, and a counterweight ball 5 is connected to the lower end of the piston rod 4, and the counterweight ball 5 makes the piston rod 4 extend to the lowest point in a normal state; the upper part of all piston cylinders 3 is also connected to a measuring branch pipe 7, and the other end of the measuring branch pipe 7 is connected to a measuring main pipe 6, and the other end of the measuring main pipe 6 is connected to the bottom of the measuring box 8, and an exhaust pipe 14 is fixed through the top of the measuring box 8;

[0026] like Figure 3 As shown, when the piston rod 4 is extended to the shortest position, the measuring medium in the measuring box 8 is at the highest point; Figure 2 As shown, when the piston rod 4 is extended to the longest position, the measuring medium in the measuring box 8 is located at the lowest point, and the volume of the measuring box 8 is equal to the volume of the test medium that all piston cylinders 3 can accommodate, so that the liquid medium in the measuring box 8 can directly reflect the extension and retraction of the piston rod 4 and indirectly reflect the volume in the material frame 1.

[0027] like Figure 4 As shown in the figure, for the convenience of explanation, the piston cylinder 3 and the piston rod 4 are arranged at six locations in the length direction of the material frame 1 and at four locations in the width direction. In actual use, the more piston cylinders 3 and piston rods 4, the better, so that the smaller the measured area of ​​the piston cylinder 3, the more accurate the measured volume ratio. Generally, the distance between adjacent piston cylinders 3 is less than 5 cm, and the measured data is closer to the actual controlled volume ratio.

[0028] The measuring box 8 is a cylindrical body, and the measuring box 8 is made of transparent plastic material, so that the overall telescopic condition of the piston rod 4 can be obtained directly by checking the depth of the transformer oil in the measuring box 8; the outer part of the measuring box 8 is provided with scale values ​​from top to bottom, and the scale values ​​are used to show the percentage of the volume of the measuring medium 10 in the measuring box 8 to the volume of the measuring box, and the data size gradually increases from top to bottom; the measuring box 8 is also provided with a sealing plug 11, and the sealing plug 11 separates the exhaust pipe 14 from the inside of the measuring box 8. For example, the height of the measuring box 8 is divided into ten equal parts, and the scale values ​​corresponding to the scale are marked with percentages. The volume of the measuring box 8 is equivalent to the volume of all piston cylinders 3, so it can intuitively reflect the telescopic length of the piston rod 4, thereby indirectly reflecting the volume condition in the storage material box 1, and the percentage measurement value on the measuring box 8 is also equivalent to the size of the volume ratio in the material frame 1. The bottom of the bottom cover 2 is provided with a guide frame to facilitate the bottom cover 2 to be docked and installed on the material frame 1, and the guide frame is located on the inner side of the material frame 1, and the cross section of the guide frame is a triangle or an isosceles trapezoid. A bracket is provided at the upper end of the bottom cover 2, the measuring box 8 is mounted on the bracket, and the bottom cover is mounted on the multi-axis robot arm through the bracket.

[0029] Example 2

[0030] like Figure 5 As shown, the difference between Example 2 and Example 1 is that, in Example 2, a sealing plug 11 is not provided, but a liquid level sensor 9 is provided in the measuring box 8. The liquid level sensor 9 is used to detect the height of the measuring medium in the measuring box 8. The liquid level sensor 9 is preferably a float type liquid level sensor or a buoy type liquid level sensor; an air bag 13 is provided and connected to the air outlet end of the exhaust pipe 14. When the piston rod 3 is retracted to the shortest, the air bag 13 is in a positive pressure state. The volume of the air bag 13 is larger than the volume of the measuring box 8, preferably 1.2 times the volume of the measuring box 8; the inflated air bag 13 can keep the pressure of the sealed pipeline at a certain level at all times during operation, and does not affect the operation of the liquid level sensor 9.

[0031] Working principle and process: When using the present invention, the best way is to install the device on a multi-axis robotic arm or a multi-axis truss. In normal state, the piston rod 4 always droops and retracts to the longest point under the action of the counterweight ball 5. When measuring, the piston rod 4 at each location represents a part of the volume that has been subdivided in the material frame. Before measurement, the robotic arm moves to the top of the material frame 1 and aligns with the material frame. During testing, the robotic arm moves vertically downward until the bottom cover 2 contacts the material frame 1 and stops moving downward. In the process of the robot arm driving the bottom cover 2 to move downward, when the weight ball 5 at the bottom of the piston rod 4 contacts the material in the material frame 1, the piston rod 4 will return the measuring medium in the piston cylinder 4 to the measuring box. Since the volume of the measuring box 8 is equal to the volume of all piston cylinders 4 that can hold the test medium, the expansion and contraction of the piston rod 4 corresponds to the volume ratio of a certain area (that is, the expansion and contraction length of the piston rod 4 represents the vacant height of a certain area), so the expansion and contraction of all piston rods 4 can be reflected in the liquid level of the measuring box, and the length of each piston rod 4 represents the idle height of a certain area, so it is obvious that when the volume in the measuring box is equal to the volume of all piston cylinders 3, the volume ratio of the idle part in the measuring box 8 is the volume ratio of the idle space in the material frame 1; the present invention indirectly reflects the idle space volume ratio of the material frame on the liquid level of the measuring box 8, which not only enables the idle space volume ratio of the material frame 1 that is difficult to measure to be measured, but also has a fast measurement speed and a relatively accurate volume ratio, so that the volume of the material frame 1 can be effectively detected, so that the storage space of the stereoscopic warehouse can be fully utilized later.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
