Description

Technical Field

[0001] The invention belongs to the field of mechanical technology and relates to a rice dumpling processing system, in particular to a safety monitoring device for rice dumpling feeding and conveying and a monitoring method thereof. Background Art

[0002] Zongzi, originated from the Han Chinese, is said to be related to the commemoration of the ancient poet Qu Yuan who committed suicide by drowning. It is one of the items for the Dragon Boat Festival. Legend has it that zongzi was made to commemorate Qu Yuan who committed suicide by drowning. The purpose was to prevent Qu Yuan's body from being eaten by fish and damaged, so zongzi was used as bait. Therefore, on that day every year, people would send zongzi to each other as a commemoration of Qu Yuan.

[0003] Now, zongzi is not only eaten as food for the Dragon Boat Festival, but also eaten as breakfast or snacks in daily life. The demand for zongzi is very large. At present, the production process of zongzi generally adopts semi-automatic production, and the material needs to be packed manually during the production process. Generally, the zongzi material is placed at the worker's workstation by manual transportation, and the worker grabs the appropriate zongzi material for packaging according to his own feeling. However, the weight of the zongzi material grabbed by different workers is also different, and the weight of the zongzi material grabbed by the same worker each time is also different, resulting in different sizes of packaged zongzi. Now a device for automatically distributing zongzi material has also been designed, wherein during the process of feeding and conveying, the amount of zongzi material in each conveying trough cannot be monitored, which causes the zongzi material to spill during the transmission process, causing equipment pollution, and it is easy to breed bacteria for a long time, affecting the quality of the zongzi material, leading to food safety problems; in addition, it increases the difficulty of cleaning the equipment and reduces production efficiency. Summary of the invention

[0004] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose a safety monitoring device and a monitoring method for zongzi feeding and conveying that controls the amount of zongzi materials transmitted by setting multiple monitoring points to avoid spilling of excess zongzi materials.

[0005] The object of the present invention can be achieved through the following technical scheme: a safety monitoring device for feeding and conveying zongzi, comprising a controller, a feeding box and a conveying pipeline, a feeding hopper is arranged at the bottom of the feeding box, an electric valve is arranged on the outlet of the feeding hopper, a rotary conveyor belt is arranged in the conveying pipeline, the rotary conveyor belt comprises a horizontal input section, a lifting section and a horizontal output section, the horizontal input section is connected to the lower end of the lifting section, the horizontal output section is connected to the upper end of the lifting section, a material receiving port is arranged on the upper side of the horizontal input section, the material receiving port is connected to the lower side of the feeding hopper, a discharge port is arranged on the lower side of the horizontal input section, a collecting box is arranged below the discharge port, a discharge hopper is arranged below the end of the horizontal output section, and conveying troughs are evenly spaced in the middle of the surface of the rotary conveyor belt along the length direction, the conveying troughs are separated by partitions, and there are two sides of the rotary conveyor belt The side extends outward to form a transmission edge that contacts the transmission wheel; photoelectric sensor 1 and photoelectric sensor 2 are fixedly installed on the side of the material receiving port of the horizontal input section, and the photoelectric sensor 1 and photoelectric sensor 2 are arranged front and back along the conveying direction of the horizontal input section. A lifting and scraping assembly is arranged between the photoelectric sensor 1 and the photoelectric sensor 2, and the lifting and scraping assembly includes a lifting cylinder located on both sides of the material receiving port, and the lifting cylinder has an upward telescopic rod, and a horizontal axis is fixedly connected between the two telescopic rods, and a scraping roller is rotatably sleeved on the horizontal axis; a material receiving distance sensor is set above the material receiving port, and the material receiving distance sensor is located in front of the photoelectric sensor 1, and the probe of the material receiving distance sensor is downwardly aligned with the inner cavity of the conveying trough; the controller connects the electric valve, photoelectric sensor 1, photoelectric sensor 2, lifting cylinder and material receiving distance sensor through a circuit.

[0006] In the safety monitoring equipment for feeding and conveying zongzi, the rotary conveyor belt forms a Z-shaped structure, and the zongzi materials are lifted and conveyed from the lower part to the upper part through the rotary conveyor belt, providing continuous feeding for the next processing step.

[0007] In the above-mentioned safety monitoring equipment for feeding and conveying rice dumplings, the top of the feeding box is open, and a feeding distance sensor is installed above the opening. The probe of the feeding distance sensor is pointed downward at the inner cavity of the feeding box, and the controller is connected to the feeding distance sensor through a circuit.

[0008] In the above-mentioned safety monitoring equipment for feeding and conveying rice dumplings, the partition is inclined toward the forward direction of the rotary conveyor belt, and the inclination angle of the partition is 35° to 50°.

[0009] In the above-mentioned safety monitoring equipment for feeding and conveying rice dumplings, a plurality of transmission wheels are arranged at the transmission edge of the rotary conveyor belt, one of which is fixedly connected to a transmission motor via a rotating shaft, and the controller is connected to the transmission motor via a circuit.

[0010] In the above-mentioned safety monitoring equipment for rice dumpling feeding and conveying, a bracket is arranged beside the horizontal input section, and the bracket includes a vertical beam at the lower part and a horizontal beam at the upper part, the end of the horizontal beam is located directly above the material receiving port, and the material receiving distance sensor is fixedly mounted on the end of the horizontal beam.

[0011] The monitoring method of the safety monitoring equipment for the feeding and conveying of zongzi includes the following contents:

[0012] 1) The glutinous rice dumplings in the feeding box are discharged to the horizontal input section of the rotary conveyor belt through the feeding hopper, poured into the conveying trough through the receiving port, and transported to the horizontal output section through the lifting section. When the rotary conveyor belt is turned over, the glutinous rice dumplings are poured out from the conveying trough and discharged to the next process through the discharging hopper;

[0013] 2) First, set the limit height value 1 and the limit low value 1 of the rice dumpling material in the conveying trough in the controller. When the conveying trough is transmitted to the bottom of the feeding hopper of the feeding box, the moment distance value of the inner cavity of the conveying trough is sensed by the material receiving distance sensor. The material receiving distance sensor to the bottom of the conveying trough is a fixed height value 1. The difference between the fixed height value 1 and the moment distance value is the moment height value of the rice dumpling material in the conveying trough. When the moment height value is lower than the limit height value 1, it means that the rice dumpling material in the conveying trough is not full. The controller controls the rotary conveyor belt to stop until the rice dumpling material in the conveying trough reaches the limit height value 1. The controller controls the rotary conveyor belt to continue running.

[0014] 3) When the conveying trough is loaded with zongzi materials and passes through the photoelectric sensor 1, if the photoelectric sensor 1 does not sense that it is blocked by the zongzi materials, it means that the amount of zongzi materials in the conveying trough is appropriate, so that it will not spill out during the rising process, and the controller does not issue a command, so that the equipment runs as usual;

[0015] 4) If the photoelectric sensor senses that there is a blockage of zongzi materials, it means that there is too much zongzi materials in the conveying trough. The controller controls the lifting cylinder to lower the scraper roller, so that the scraper roller contacts and scrapes off the excess zongzi materials on the top of the conveying trough by rolling. The excess zongzi materials are rolled to the rear conveying trough or fall into the collecting box;

[0016] 5) When the conveying trough is loaded with rice dumplings and passes through the photoelectric sensor 2, the photoelectric sensor 2 is used to check whether the rice dumplings in the conveying trough meet the requirements after scraping. If the photoelectric sensor 2 does not sense that it is blocked by rice dumplings, it means that the amount of rice dumplings in the conveying trough is appropriate, and the controller does not issue a command to keep the equipment running as usual; if the photoelectric sensor 2 senses that it is blocked by rice dumplings, it means that there is still excessive rice dumplings in the conveying trough, and the controller controls the rotary conveyor belt to stop and alarm.

[0017] In the monitoring method of the above-mentioned safety monitoring equipment for feeding and conveying of rice dumplings, firstly, the upper limit height value 2 and the lower limit depth value 2 of the rice dumpling material in the feeding box are set in the controller, and the real-time distance value of the rice dumpling material to the inside of the feeding box is sensed at every moment by the feeding distance sensor. The feeding distance sensor to the bottom of the feeding box is a fixed height value 2, and the difference between the fixed height value 2 and the real-time distance value is the real-time height value of the rice dumpling material in the feeding box. When the real-time height value is higher than the upper limit height value 2, the controller controls to stop pouring the rice dumpling material into the feeding box; when the real-time height value is lower than the lower limit depth value 2, the controller controls to start pouring the rice dumpling material into the feeding box.

[0018] In the monitoring method of the above-mentioned safety monitoring equipment for feeding and conveying of rice dumplings, an inclined structure is formed inside the conveying trough by the inclined setting of the partition, so that the rice dumpling materials can be held during vertical lifting, so that the rice dumpling materials can be safely conveyed in the vertical direction.

[0019] In the monitoring method of the safety monitoring equipment for feeding and conveying of rice dumplings mentioned above, in step 2), when the height value at a moment is zero, it means that the conveying trough is in an empty state, the controller controls the rotary conveyor belt to stop, and the controller controls the electric valve at the outlet of the feeding hopper to open to the maximum state to feed the conveying trough.

[0020] In the monitoring method of the above-mentioned safety monitoring equipment for feeding and conveying of rice dumplings, in step 4), when the photoelectric sensor does not sense being blocked by rice dumpling materials, it means that the amount of rice dumpling materials in the subsequent conveying trough is appropriate, and the controller controls the lifting cylinder to raise the scraper roller to separate the scraper roller from the rice dumpling materials.

[0021] Compared with the prior art, the safety monitoring device and monitoring method for feeding and conveying zongzi have the following advantages:

[0022] The distance sensor is used to measure the amount of zongzi material in the vertical direction, and the photoelectric sensor is used to monitor the amount of zongzi material in the horizontal direction. The two work together to effectively control the appropriate amount of zongzi material in the conveyor trough to avoid spilling of zongzi material during vertical transportation, thus reducing the cleaning operation of the equipment, ensuring a clean environment for the equipment, ensuring food quality, and improving production efficiency.

[0032] The monitoring method of the safety monitoring equipment for the feeding and conveying of zongzi includes the following contents:

[0033] 1) The glutinous rice dumplings in the feeding box 1 are discharged to the horizontal input section 5 of the rotary conveyor belt through the feeding hopper 2, poured into the conveying trough through the receiving port, and transported to the horizontal output section 13 through the lifting section 12. When the rotary conveyor belt is turned over, the glutinous rice dumplings are poured out from the conveying trough and discharged to the next process through the discharging hopper 14;

[0035] 3) When the conveying trough is loaded with zongzi materials and passes through the material receiving distance sensor 8, if the material receiving distance sensor 8 does not sense that it is blocked by zongzi materials, it means that the amount of zongzi materials in the conveying trough is appropriate so that it will not spill out during the rising process, and the controller does not issue any command, so that the equipment operates as usual;

[0036] 4) If the material receiving distance sensor 8 senses that there is a blockage of zongzi materials, it means that there is too much zongzi materials in the conveying trough.

The excess zongzi materials are rolled to the rear conveying trough or fall into the collecting box 6;

[0037] 5) When the conveying trough is loaded with rice dumplings and passes through the photoelectric sensor 11, the photoelectric sensor 11 is used to check whether the rice dumplings in the conveying trough meet the requirements after scraping. If the photoelectric sensor 11 does not sense that it is blocked by rice dumplings, it means that the amount of rice dumplings in the conveying trough is appropriate, and the controller does not issue any instructions to keep the equipment running as usual; if the photoelectric sensor 11 senses that it is blocked by rice dumplings, it means that there is still excessive rice dumplings in the conveying trough, and the controller controls the rotary conveyor belt to stop and alarm.

[0038] First, set the upper and lower limit values ​​2 and 3 of the rice dumpling material in the feeding box 1 in the controller, and sense the real-time distance value of the rice dumpling material to the feeding box 1 at every moment through the feeding distance sensor 3. The feeding distance sensor 3 to the bottom of the feeding box 1 is a fixed height value 2, and the difference between the fixed height value 2 and the real-time distance value is the real-time height value of the rice dumpling material in the feeding box 1. When the real-time height value is higher than the upper and lower limit values ​​2, the controller stops pouring the rice dumpling material into the feeding box 1; when the real-time height value is lower than the lower and lower limit values ​​2, the controller starts pouring the rice dumpling material into the feeding box 1.

[0039] By setting the partition plate in an inclined manner, an inclined structure is formed inside the conveying trough, so that the rice dumpling materials can be held during vertical lifting, thereby allowing the rice dumpling materials to be safely conveyed in the vertical direction.
