A capping device for a medical disc-type filling apparatus and a capping method therefor, belonging to the technical field of intelligent filling. A bottle clamping device (206) is mounted on a body of a trapezoidal base (1), and a displacement sensor (205) is mounted on a connection block (202) of a capping unit (2), such that a screwed state of a bottle cap (4) can be recorded in real time, and the length of the bottle cap (4) that moves down by screwing is recorded, and a rubber piece (5091) made of a rubber material is provided at an end portion of an arc-shaped support column (507) and a slide block (5082) of the bottle clamping device (206), the rubber piece (5091) on the periphery of a filling bottle (3) effectively prevents the traces leaving on the filling bottle (3) due to excessive clamping force, the rubber piece (5091) is provided with a rhombic knurl pattern on the surface thereof, so as to prevent the filling bottle (3) from sliding. The mechanical mode for fixing the filling bottle reduces the labor intensity of an operator, and using a servo motor to control a tightening joint (2064) and using the displacement sensor (205) to record the screwed state of the bottle cap (4) improve the qualification rate of the product.
A: A pipeline type intelligent spraying robot and a working method thereof. The robot comprises a frame (1), multi-wheel drive units (2), and a pre-tensioning and reducing mechanism 3. Three multi-wheel drive units (2) are provided on the body of the frame (1), drive wheels (205) are distributed at 120°, and a drive motor (206) and the drive wheel (205) are fixed on the same support, so that the drive unit (2) is simplified, thereby economizing a design space. In order to prevent the drive wheel (205) from slipping, a rubber material is surrounded on the periphery of the drive wheel (205) to increase a static friction coefficient. A synchronous belt (212) is used as the transmission mode of the drive motor (206) and the drive wheel (205), so that a constant transmission ratio during transmission is maintained, stable transmission and vibration damping are implemented, and maintenance can be facilitated during use. Three independent torque motors are used so that the robot is driven to smoothly pass through a circular bend pipe by means of differential speeds between three wheels.
B: A device and method for detection of liquid impurities in bottle set filling; the detection process thereof is as follows: at initial bottle-pickup station (1010), set clamping mechanism (30) simultaneously gripping a set of filling bottles (66) from a plurality of bottle guide slots (65) of bottle feed mechanism (60); the set of filling bottles (66) to be tested is moved to a detection station (1023) equipped with a lighting system (70), and the set of filling bottles (66) is rotated at high speed, the rotational motion of the liquid inside the bottle forcing precipitated impurities in the liquid to rise; while the liquid in filling bottles (66) is in rotation, a sequence of images are taken, of the liquid in rotation, by image acquisition system (50) electrically connected to computer analysis control system (90), and computer analysis system (90) analyzes the images, calculates the size of the insoluble impurity particles, and determines whether same exceed specifications; lastly, a sorting mechanism (80) sorts out acceptable product. The design approach of the detection device and method makes use of set-type gripping, simultaneous movement, simultaneous detection, and simultaneous bottle unloading, and the invention has the advantage of a high detection rate.
C: Disclosed is a non-contact hot-filling valve, comprising a hollow cavity (1) arranged on a frame, a valve rod (2) arranged in the hollow cavity (1) and capable of moving up and down, a liquid inlet (3) in communication with the hollow cavity (1), a filling opening (4) arranged below the hollow cavity (1), a driving mechanism (5) for driving the valve rod (2) to move up and down to connect or disconnect the liquid inlet (3) from the filling opening (4), a filling backflow opening (6) in communication with the hollow cavity (1), and a control mechanism (7) for controlling opening and closing of the filling backflow opening (6). The valve uses non-contact filling, thereby preventing material splashing and reducing waste of drinks. By arranging the filling backflow opening and the control mechanism, no liquid remains in the valve after hot filling, and it is possible to ensure a liquid enters filling bottles at a preset temperature.
D: An industrial full-automatic capping machine, comprising a machine frame (1), a conveying device, a control device, a support device (2), a cap feeding device (3) and a tightening device (4); the cap feeding device (3), the tightening device (4), the support device (2) and the conveying device being arranged on the machine frame (1) successively, from top to bottom; the support device (2) comprising an inner support device, (5) an outer support device (6), and an ultrasonic detector (7) being provided above the inner support device (5); one end of the tightening device (4) being arranged in a sliding manner, the inside of the other end being provided with a rotating chain (8), and a pressure sensor (9) being provided on the rotating chain (8). The full-automatic capping machine can realize automation of a capping process, not only being capable of effectively controlling the cap tightening degree, reducing the production cost, but also reducing the difficulty of work, increasing working efficiency, being practical and having a wide scope of application.
