Description

Technical Field

[0001] The utility model relates to the technical field of material conveying and mixing equipment, and particularly relates to a full-automatic interlayer material transfer and mixing system. Background Art

[0002] In the fields of food, tablets, and chemical production mixing, the production equipment is large in volume and usually involves multiple floors. The supply of materials needs to be transported through the floors.

[0003] The problems existing in the prior art are as follows: In such production environments, it is usually necessary to set up feeding, production mixing, packaging and other links on different floors to standardize the process and management. During production, according to the process requirements, the required materials are transported between equipment on different floors through elevators, hoists and other means. This results in long material transfer time, a large amount of labor, and incoherence, affecting the overall efficiency of interlayer production.

[0004] Therefore, it is necessary to design a full-automatic interlayer material transfer and mixing system to realize the automatic production linkage of each equipment between different floors and provide the detection and feedback interaction of key production information. Summary of the Utility Model

[0005] In order to solve the above technical deficiencies, the utility model provides a full-automatic interlayer material transfer and mixing system.

When the feeding port is docked with the hopper feed inlet, the first docking airbag expands to fix the relative position between the feeding port and the feed inlet. The airbag pressure sensor detects the air pressure signal of the first docking airbag, and the piston rod position sensor detects the position signal of the extension and retraction state of the piston rod of the lifting cylinder;

[0011] The discharging station is provided with a second valve opener and a second valve opener position sensor at the position corresponding to the discharging butterfly valve. The second valve opener drives the opening and closing of the discharging butterfly valve, and the second valve opener position sensor detects the position signal of the extension and retraction states of the second valve opener; the second diagonal position sensor detects the diagonal position signal of the hopper moving frame at the material receiving station.

[0012] A further setting of the present utility model: The mixer is provided with an assembly position sensor, a middle limit sensor of the electric push rod, a mixing station sensor of the electric push rod, and a pop-up position sensor of the anti-falling device.

[0013] A further setting of the present utility model: The blanking pipeline is provided with an inflation port and an inflation mechanism. The inflation mechanism includes an air source pipe, a three-position five-way double-electric control solenoid valve, a three-way pipe, and a first pressure sensor. The three-position five-way double-electric control solenoid valve conducts air from the air source to the inside of the blanking pipeline according to the signals of the second diagonal position sensor and the second airbag air pressure sensor, and cuts off the air source passage according to the signal of the first pressure sensor.

[0014] A further setting of the present utility model: The blanking pipeline is provided with a lead-out interface on the downstream packaging floor. The lead-out interface is provided with a discharging valve. The packaging machine equipment is provided with a receiving hopper, and the receiving hopper is communicated with the lead-out interface. The receiving hopper is provided with a high material position sensor and a low material position sensor along the vertical direction. The low material position sensor is signal-linked with the discharging valve to control the opening and closing of the discharging valve;

[0015] The blanking pipeline is provided with an exhaust port and an exhaust mechanism. The exhaust mechanism includes an air source pipe, a vacuum generator, a three-way pipe, a second pressure sensor, and a two-position three-way single-electric control solenoid valve. The two-position three-way single-electric control solenoid valve opens and closes the air source passage according to the signal of the high material position sensor; The packaging machine equipment is provided with a star valve on the discharging side of the receiving hopper.

[0016] Advantages of the present application: Through the feedback of sensor information set at the upstream feeding floor, the middle production floor, and the downstream packaging floor, the present application realizes the acquisition and linkage of multiple key information on the states of various equipment at the feeding station, the states of hoppers, the states of mixers, the states of various equipment at the discharging station, and the states of packaging machines, thereby realizing the production process of automatic transfer, mixing, and packaging of materials between floors.

[0017] Specifically, at the material receiving station, a diagonal position sensor is used to determine whether the hopper has moved to the designated material receiving station. The lifting cylinder drives the extension section of the pipeline at the feeding port to be docked with the hopper inlet. After the feeding port and the hopper inlet are aligned, the first docking airbag expands to fix the relative position between the feeding port and the inlet. At the same time, the airbag pressure sensor detects the air pressure signal of the first docking airbag, and the piston rod position sensor detects the position signal of the extension and retraction states of the piston rod of the lifting cylinder to generate a feedback signal. Then, the first valve opener is started to open the butterfly valve at the inlet. The position sensor of the first valve opener generates a feedback signal. According to the above feedback signals, the upstream feeding floor recognizes that the hopper has entered the material receiving state, and the material handling equipment (such as a vacuum suction crane, an AGV automatic guided vehicle) assists the bagged material to enter the automatic unpacking machine, and then the material enters the feeding pipeline and the hopper.

[0018] After the upstream feeding is completed, according to the signal for closing the blanking valve and after a few seconds of delay, the sensor signals for the closing of the valve opener, the detection that the airbag pressure is exhausted, the lifting cylinder being retracted in place, and the valve opener being retracted in place are detected. After verification, the hopper is transferred to the mixer. At this time, the diagonal position sensor signal is lost and fed back to the upstream feeding floor.

[0019] When the hopper is assembled to the mixer, according to the assembly position sensor, it is confirmed that the hopper is assembled in place and the frame is in a vertical position. Then, the electric push rod synchronously lifts the hopper, and the top servo and the clamping servo are started and stopped at the set torque. The hopper is synchronously lifted to the mixing position, and the mixer starts mixing until it stops according to the preset process.

[0020] After the mixer stops, the hopper is unloaded and moved to the discharging station. The second diagonal position sensor is triggered to generate a signal that the hopper is in place. Then, the blanking interface of the blanking pipeline is docked with the hopper outlet. The second airbag is inflated to fix the docking state and generates an air pressure signal. At the same time, the inflation mechanism set in the blanking pipeline is started. After detecting that the air pressure in the pipeline meets the requirements, it is closed and a signal is generated. Then, the second valve opener is started according to the above signals to open the outlet butterfly valve, and the material enters the blanking pipeline from the hopper and then falls into the receiving hopper of the packaging machine equipment.

[0021] The receiving hopper is provided with a high-level material position sensor and a low-level material position sensor in the depth direction to detect the remaining amount of material in the receiving hopper. When the material in the receiving hopper is insufficient, the material height is lower than the low-level material position sensor, generating a signal, and then controlling the discharge valve to open to replenish the discharged material. When the material exceeds the high-level material position sensor, a signal is generated to control the start of the exhaust mechanism. When the material in the packaging machine equipment is insufficient, the star valve is opened to allow the material in the receiving hopper to enter the packaging machine equipment.

[0041] Specific settings are as follows: At the material receiving station 18, the diagonal position sensor determines whether the hopper 2 has moved to the specified material receiving station 18. The lifting cylinder 163 drives the extension section 162 of the pipeline at the feeding port to be docked with the feeding port of the hopper 2. When the feeding port is aligned with the feeding port of the hopper 2, the first docking airbag 164 expands to fix the relative position between the feeding port and the feeding port.
