[0023] Example
[0024] like Figure 1-3As shown, the present embodiment provides a volume measuring device applied to warehousing logistics, including a frame 1, a gantry 2 is provided in the middle of the frame 1, a conveyor belt 3 is bolted and fixedly connected to the frame 1 below the gantry 2, the conveyor belt 3 is a belt conveyor belt 3 in the prior art, a first measuring mechanism 4 and a second measuring mechanism 5 are respectively provided on the gantry 2, the first measuring mechanism 4 and the second measuring mechanism 5 are arranged perpendicular to each other, the first measuring mechanism 4 and the second measuring mechanism 5 are used to detect the width and height information of the object 9; an encoder 6 is provided at the bottom of the frame 1, the encoder 6 is arranged against the conveyor belt 3, the moving speed of the conveyor belt 3 is detected by the encoder 6, so as to calculate the length information of the object 9 and track the object 9; a control box 7 is bolted and fixedly installed on the side of the frame 1, and the control box 7 is electrically connected to the first measuring mechanism 4, the second measuring mechanism 5 and the encoder 6 through wires.
[0025] The first measuring mechanism 4 includes a first grating signal transmitter 41 and a first grating signal receiver 42 , and the first grating signal transmitter 41 and the first grating signal receiver 42 are respectively arranged at the top and the bottom of the gantry 2 .
[0026] The second measuring mechanism 5 includes a second grating signal transmitter 51 and a second grating signal receiver 52 , and the second grating signal transmitter 51 and the second grating signal receiver 52 are fixedly connected to two sides of the gantry 2 , respectively.
[0027] The first measuring mechanism 4 and the second measuring mechanism 5 have the same principle. When the measured object 9 passes through the measuring area, the infrared light emitted by the grating transmitter is blocked by the object 9. The grating receiver forms a certain trigger signal according to the blocked infrared light beam and sends it to the controller. The system trigger time is equal to the time when the object 9 passes through the measuring area, and the controller will automatically generate an index number when the system is triggered. The controller also receives the pulse signal of the encoder 6. The controller will track the movement direction and position of the object 9 in the channel according to the pulse signal of the encoder 6. After waiting for the object 9 to pass through the measuring area completely, the controller receives the measurement data sent by the first measuring mechanism 4 and the second measuring mechanism 5. The controller binds the measurement data with the corresponding index number and sends the integrated data to the PLC or the host computer to complete the measurement.
[0028] Furthermore, a notch is provided in the middle of the conveyor belt 3, and the first grating signal transmitter 41 and the first grating signal receiver 42 correspond to the positions of the notch. In the present embodiment, the conveyor belt 3 is divided into two sections, front and rear sections, with a notch left between the two ends to facilitate the passage of the optical signal emitted by the first grating signal transmitter 41.
[0029] Furthermore, a transparent protective cover 43 is provided on the outer side of the first grating signal receiver 42 , and the first grating signal receiver 42 is arranged at the bottom of the gantry 2 , and is protected by the protective cover 43 to prevent dust and the like adhering to the object 9 from falling and being contaminated.
[0030] Furthermore, a dust removal mechanism is also included, the dust removal mechanism includes a dust removal motor 82, a fixed rod 21 is integrally formed at the bottom of the gantry 2, the side bolts of the fixed rod 21 are fixedly connected to the first grating signal receiver 42, the top bolts of the fixed rod 21 are fixedly connected to the blowing pipe 81, the side of the blowing pipe 81 is provided with a blowing port 811 near the first grating signal receiver, and the output end of the dust removal motor 82 is connected to one end of the blowing pipe 81 through a pipeline. By starting the dust removal motor 82 to generate strong wind entering the blowing pipe 81, the dust removal motor 82 generates a strong airflow, and the airflow is transported to the blowing port 811 through the pipeline. The airflow is sprayed to the surface of the transparent protective cover 43 outside the first grating signal receiver 42 at the bottom through the blowing port 811, so that the dust and foreign matter on the surface are cleaned. Not only can the dust accumulation problem of the grating be effectively solved, the measurement accuracy of the grating and the stability of the equipment are improved, but also the convenience of cleaning and maintenance is ensured due to the detachable structure of the protective cover 43.
[0031] Furthermore, the encoder 6 is connected to the frame 1 through a mounting assembly, which includes a fixing plate 61, which is fixedly connected to the frame 1 and located at the bottom of the conveyor belt 3. A mounting rod 62 is fixedly connected to the surface of the fixing plate 61, one end of the mounting rod 62 is fixedly connected to a connecting rod 63, and a rotating rod 64 is hinged at the top of the connecting rod 63. One end of the rotating rod 64 is connected to the encoder 6, and the other end of the rotating rod 64 is fixedly connected to a tension spring 65, and one end of the tension spring 65 is fixedly connected to the bottom of the connecting rod 63. The encoder 6 is installed below the conveyor belt 3, and its roller contacts the belt surface of the conveyor belt 3. The belt runs and the roller rotates, which is used to measure the speed of the belt. When the object 9 enters the measurement area, the encoder 6 sends a pulse to the controller, and the controller tracks the position of the object 9. In addition, the encoder 6 pulls one end of the rotating rod 64 downward through the tension spring 65, thereby driving the encoder 6 upward to press against the bottom of the conveyor belt 3, so that the encoder 6 and the conveyor belt 3 are in close contact, thereby improving the measurement accuracy.
[0032] Among them, the surface of the control box 7 is hinged with a box door, and a controller is arranged inside the control box 7. The controller is an MSC800 controller in the prior art. The controller is provided with a communication interface for connecting with the first measuring mechanism 4 and the second measuring mechanism 5, and communicates with the outside through various flexible interfaces, so as to upload the measurement data to the PLC or the host computer.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present disclosure.
