Description

Technical Field

[0001] The invention relates to the technical field of material mixing, and in particular to a material mixing detection system. Background Art

[0002] Mixing devices are widely used in metallurgy, mining, coal, electricity, ports and other industries. They are one of the important equipment for mixing materials during bulk material transportation. In the actual production process, two or more materials need to be mixed. Generally, multiple materials are put into a mixing hopper for full mixing. Finally, after uniform mixing, they are input into a designated container for repackaging for use in the next process. The current problems are:

[0003] 1. During the material mixing stage, it is easy to make the materials unclear, which makes it easy to make mistakes in material mixing, further leading to material waste, thereby increasing processing costs.

[0004] 2. During the charging stage of mixed materials, for example, when the charging container is in a barrel shape (i.e., a semi-finished product barrel), if the outlet flow rate of the mixing device is too small, the materials will accumulate into a material cone in the semi-finished product barrel, causing the material cone to block the outlet of the mixing device, and workers are required to flatten the material cone to fully fill the internal space of the semi-finished product barrel. This is time-consuming and labor-intensive, and affects the charging efficiency of the materials. Summary of the invention

[0005] The object of the present invention is to provide a mixing detection system, which can avoid the problem of wrong material taking during mixing, resulting in waste of material and thus increasing processing costs.

[0006] In order to achieve the above-mentioned purpose, a mixing detection system is provided, including a controller, a display screen, an RFID reading device, a two-dimensional code scanning device and a semi-finished product barrel; the RFID reading device is arranged on the mixing device, and is used to read the electronic tag set on the raw material bag; the electronic tag stores the basic information of the material raw material; a two-dimensional code label is placed on the outer barrel wall of the semi-finished product barrel; the two-dimensional code scanning device is arranged on the front side of the discharge port of the mixing device, and is used to scan the two-dimensional code label on the outer barrel wall of the semi-finished product barrel, and the two-dimensional code label stores the raw material formula information; the display screen is used to display the basic information stored in the electronic tag and the two-dimensional code label scanned by the two-dimensional code scanning device, and the controller is used to compare whether the basic information of the material raw material and the raw material formula information are consistent, and if they are inconsistent, an alarm message is generated.

[0007] Furthermore, it also includes an audible and visual alarm, which is used to broadcast according to the alarm information.

[0008] Furthermore, the semi-finished barrel is placed on a rotating device, which includes a base and a turntable. The turntable is rotatably connected to the base and driven by a servo motor. A plurality of pressure sensors distributed in a matrix are provided on the upper surface of the turntable. The pressure sensors and the servo motor are electrically connected to the controller.

[0009] Further, the controller comprises:

[0010] Pressure distribution detection module: used to detect and analyze the pressure distribution diagram of the semi-finished barrel on the pallet based on the pressure sensors distributed in a matrix;

[0011] QR code scanning auxiliary module: when the semi-finished barrel is analyzed to be empty according to the pressure distribution diagram, the servo motor drives the turntable to rotate, so that the QR code scanning device scans the QR code label on the outer barrel wall of the semi-finished barrel. If no alarm information is obtained, the material discharge prompt information of the mixing device is generated;

[0012] Rotating material leveling module: when receiving the material discharge prompt information, the servo motor drives the turntable to rotate according to the pressure distribution diagram.

[0013] Furthermore, the turntable is provided with a plurality of indication patterns arranged in a concentric circle shape and used to indicate the placement position of the semi-finished barrels, the indication patterns include size information of the semi-finished barrels, and the turntable is concentric with the indication patterns.

[0014] Furthermore, the controller further comprises:

[0015] Placement accuracy analysis module: used to obtain the size information of the semi-finished barrel and the weight information when fully filled according to the read QR code label, and then analyze whether the placement position of the semi-finished barrel is correct according to the pressure distribution diagram. If not, analyze the offset, and combine the weight information when fully filled and the rotation speed of the turntable to analyze whether there is a risk of sliding due to overall offset of the semi-finished barrel. If so, a risk warning and a placement prompt will be given to indicate that the semi-finished barrel is placed incorrectly.

[0016] Furthermore, an LED light strip arranged in a ring shape is provided outside the indication pattern, and the LED light strip is electrically connected to a controller, and the controller includes the following modules:

[0017] Placement prompt module: used to obtain the size information of the semi-finished barrel according to the read QR code label, and control the corresponding LED light strip according to the size information.

[0018] Principles and advantages:

[0019] 1. When the material collector mixes the materials, he needs to open the bag of raw materials he has received and put it into the mixing device. The bag of raw materials needs to pass through the RFID reading device, so the RFID reading device can read the basic information of the raw materials stored in the electronic tag and display it on the display. The QR code scanning device is set in front of the discharge port of the mixing device, and the semi-finished product barrel needs to be placed at the discharge port of the mixing device, so the QR code scanning device can scan the QR code label and display it on the display, and then the controller compares the basic information of the raw materials and the raw material formula information to see if they are consistent. If they are inconsistent, an alarm message is generated, and the sound and light alarm is used for an alarm prompt.

[0020] 2. Since the material will be pushed into a material cone in the semi-finished barrel, the material cone will block the outlet of the mixing device. This solution is equipped with a rotating device, and the semi-finished barrel needs to be placed on the rotating device. The pressure distribution detection module can detect and analyze the pressure distribution diagram of the semi-finished barrel on the pallet based on the pressure sensors distributed in a matrix; both the empty barrel state and the loaded state can be distinguished. When the QR code scanning auxiliary module analyzes that the semi-finished barrel is an empty barrel according to the pressure distribution diagram, the servo motor drives the turntable to rotate, and the QR code scanning device scans the QR code label on the outer barrel wall of the semi-finished barrel. If no alarm information is obtained, a discharge prompt information of the mixing device is generated to prompt that the material can be discharged. When the rotating material mixing module receives the discharge prompt information, the servo motor drives the turntable to rotate according to the pressure distribution diagram. The material cone is prevented from blocking the outlet of the mixing device through the action of rotation.

[0021] 3. When the semi-finished barrel is not placed in the right position, that is, when it does not coincide with the center of the turntable, coupled with the weight of the material and the effect of rotation, the semi-finished barrel may slide under the action of centrifugal force, which may cause the semi-finished barrel to leave the turntable or damage the turntable. This solution sets a number of indicator patterns on the turntable that are arranged in concentric circles and are used to prompt the placement of the semi-finished barrel, so as to achieve an obvious prompting effect. Then, according to the pressure distribution diagram, analyze whether the placement of the semi-finished barrel is correct. If not, analyze the offset, and combine the weight information when fully loaded and the rotation speed of the turntable to analyze whether the semi-finished barrel has the risk of sliding due to overall offset. If so, a risk prompt and a prompt that the semi-finished barrel is placed incorrectly are given. Further, the placement prompt module obtains the size information of the semi-finished barrel according to the read QR code label, and controls the corresponding LED light strip according to the size information. The prompt effect is improved by the prompt of the LED light strip, especially in a working environment with poor lighting conditions. BRIEF DESCRIPTION OF THE DRAWINGS

The RFID reader is arranged on the mixing device, and is used to read the electronic tag set on the raw material bag; the electronic tag stores the basic information of the raw material; in this embodiment, the electronic tag is nailed to the raw material bag in the form of a ground cloth nail, so that the RFID reader of the RFID reader of the feeding port of the mixing device can easily identify these electronic tags. The electronic tag is fixed by a cable tie, and the raw material package number is distinguished by color to avoid confusion. The mixing device is an existing mixing device, which stirs and mixes various raw materials.

[0026] A QR code label is placed on the outer barrel wall of the semi-finished barrel; the QR code scanning device is arranged at the front side of the discharge port of the mixing device, and is used to scan the QR code label on the outer barrel wall of the semi-finished barrel, and the QR code label stores the raw material formula information; the QR code label is a paper label or a card-type label; if it is a paper label, it is pasted on the outer barrel wall of the semi-finished barrel; if it is a card-type label, a card slot is set on the outer barrel wall of the semi-finished barrel, and the QR code label is placed in the card slot, wherein the QR code needs to be exposed from the card slot. This embodiment adopts a paper label. The display screen is used to display the basic information stored in the electronic label (the package number and quantity of the raw material package that has been loaded) and the QR code label scanned by the QR code scanning device, and at the same time display whether the basic information of loading and the QR code label are consistent.

[0027] The semi-finished barrel is placed on a rotating device, which includes a base and a turntable. The turntable is rotatably connected to the base and driven by a servo motor. The upper surface of the turntable is provided with a plurality of pressure sensors distributed in a matrix. A battery and a microcontroller are provided in the turntable. The pressure sensor and the servo motor are both electrically connected to the microcontroller. The microcontroller is remotely connected to the controller.

[0028] The turntable is provided with a plurality of indication patterns which are arranged in a concentric circle and are used to indicate the placement positions of the semi-finished product barrels. The indication patterns include the size information of the semi-finished product barrels, and the turntable is concentric with the indication patterns.

[0029] An LED light strip arranged in a circular ring shape is arranged outside the indication pattern, and the LED light strip is electrically connected to the microcontroller.

[0030] The controller comprises:

[0031] Comparative analysis module: used to compare whether the basic information of raw materials and the raw material formula information are consistent. If they are inconsistent, an alarm message is generated.

[0032] Alarm module: used to allow the sound and light alarm to broadcast according to the alarm information.

[0033] Pressure distribution detection module: used to detect and analyze the pressure distribution diagram of the semi-finished barrel on the pallet based on the pressure sensors distributed in a matrix;

[0034] QR code scanning auxiliary module: when the semi-finished barrel is analyzed to be empty according to the pressure distribution diagram, the servo motor drives the turntable to rotate, so that the QR code scanning device scans the QR code label on the outer barrel wall of the semi-finished barrel. If no alarm information is obtained, the material discharge prompt information of the mixing device is generated;

[0035] Rotating material leveling module: when receiving the material discharge prompt information, the servo motor drives the turntable to rotate according to the pressure distribution diagram.

[0036] Placement accuracy analysis module: used to obtain the size information of the semi-finished barrel and the weight information when fully filled according to the read QR code label, and then analyze whether the placement position of the semi-finished barrel is correct according to the pressure distribution diagram. If not, analyze the offset, and combine the weight information when fully filled and the rotation speed of the turntable to analyze whether there is a risk of sliding due to overall offset of the semi-finished barrel. If so, a risk warning and a placement prompt will be given to indicate that the semi-finished barrel is placed incorrectly.

[0038] This solution is equipped with a rotating device, and the semi-finished barrels need to be placed on the rotating device. The pressure distribution detection module can detect and analyze the pressure distribution diagram of the semi-finished barrels on the pallet based on the pressure sensors distributed in a matrix; both the empty barrel state and the loaded state can be distinguished. When the QR code scanning auxiliary module analyzes that the semi-finished barrel is an empty barrel based on the pressure distribution diagram, the servo motor drives the turntable to rotate, and the QR code scanning device scans the QR code label on the outer barrel wall of the semi-finished barrel. If no alarm information is obtained, a discharge prompt information of the mixing device is generated to prompt that the material can be discharged. When the rotating material mixing module receives the discharge prompt information, the servo motor drives the turntable to rotate according to the pressure distribution diagram. The material cone is prevented from blocking the outlet of the mixing device through the rotation.

[0039] This solution sets up several indicator patterns arranged in concentric circles on the turntable to achieve an obvious prompting effect. Then, the pressure distribution diagram is used to analyze whether the semi-finished barrel is placed correctly. If not, the offset is analyzed, and the weight information when fully loaded and the rotation speed of the turntable are combined to analyze whether the semi-finished barrel has a risk of sliding due to overall offset. If so, a risk warning and a placement prompt that the semi-finished barrel is not placed correctly are given. The placement prompt module is further used to control the corresponding LED light strip according to the size information. The prompt effect is improved by the prompt of the LED light strip, especially in working environments with poor lighting conditions.
