A bag sealing method for carrying out external packaging on blood bag transportation comprises the following steps: 1) the sealing bag is a heat sealing bag for sealing the near opening end of the outer packaging bag 5, and the heat sealing bag is sealed by using two heat sealing strips which correspond to the upper part and the lower part of a heat sealing machine; the lower heat seal strip is arranged in a heat seal strip groove of the static sieve plate 3, and the upper heat seal strip is arranged on a heat seal machine of the heat seal frame 6 on the heat seal cylinder 14;
when a manipulator with fingertips is used for heat sealing, the heat sealing strips on the heat sealing frame of the heat sealing cylinder are arranged to be arranged in a way that when fingers are used for heat sealing the outer packaging bags, the heat sealing strips can stride over two fingers of the manipulator in the packaging bags, only the heat sealing is carried out on the parts between the fingers of the manipulator and the outer packaging bags at two sides, and the outer packaging bags form the condition of interval heat sealing; the operation sequence is that the manipulator fingers are withdrawn from the outer packaging bag after the two layers of films of the outer packaging bag are adhered together at the opening end part of the outer packaging bag, and the operation sequence is an effective method for preventing all inherent pipelines on the blood bag from escaping from the pressing state of the blood bag and dissociating to the opening of the outer packaging bag;
when using a fingerless manipulator; when fingers of a manipulator push the blood bag into the bottom of the outer packaging bag, the fingers of the manipulator immediately withdraw from the outer packaging bag, the movable sieve plate blows outwards to blow the outer packaging bag on the blood bag, the two layers of films of the outer packaging bag can be attached together at the opening end part of the outer packaging bag, then the outer packaging bag and the static sieve plate are thermally sealed on a frame by a heat sealing cylinder, a pair of sensors in a heat sealing strip groove are arranged on the frame, the opening end of the outer packaging bag is detected by a heat sealing line, and if foreign matters are detected between the two layers of films, a control center stops the thermal sealing action and immediately sends out an alarm signal. If no foreign matter exists between the two layers of films, the heat sealing cylinder pushes the heat sealing strips on the heat sealing frame to butt with the heat sealing strips in the heat sealing strip grooves of the static sieve pore plate, the outer packaging bag is subjected to a heat sealing line of a connecting line, and the outer packaging bag is subjected to heat sealing; the palm of the manipulator with or without fingertips is connected with a manipulator cylinder connecting plate, a transverse baffle extending to the upper part of the palm on the manipulator cylinder connecting plate and a manipulator cylinder connecting plate extend to the lower plate surface and block, and the manipulator palm can only rotate within 90 degrees between the extension line of a manipulator cylinder telescopic rod and a downward vertical conveyor belt;
when the movable sieve plate carries the outer packing bag, the movable sieve plate is in butt joint with the static sieve plate, negative pressure in the cavity of the static sieve plate is utilized, another layer of the outer packing bag is adsorbed, the movable sieve plate is lifted immediately, the movable sieve plate leaves the static sieve plate, an opening of the outer packing bag is opened, and in the process that the outer packing bag is opened, the movable sieve plate is adsorbed on the outer packing bag parts on two sides of the movable sieve plate, can be torn off from two sides of the driven sieve plate and is converted into two sides of the opening of the outer packing bag.
When a finger-less manipulator is used when a blood bag is loaded into the bottom of an opened outer package bag, the manipulator cylinder withdraws the fingers of the manipulator from the outer package bag. The cavity of the movable sieve pore plate is changed from negative pressure to positive pressure and blows air outwards, after the outer packaging bag adsorbed on the movable sieve pore plate is blown to the blood bag, the movable sieve pore plate is lifted up again, the palm brushes at the lower ends of the side columns of the movable sieve pore plate move transversely to turn to the outer packaging box under the condition that the blood bag cannot be swept, and the space above the static sieve pore plate is vacated; the two films of the outer packing bag at the opening end of the outer packing bag are adhered together, and then the outer packing bag opening end is detected by a heat sealing line by utilizing a pair of sensors which are arranged on a heat sealing frame of a heat sealing cylinder and in a heat sealing strip groove of a static sieve plate, if foreign matters are detected between the two films, the control center stops the heat sealing action and immediately sends out an alarm signal. If no foreign matter exists between the two films, the heat sealing cylinder 14 pushes the heat sealing strip on the heat sealing machine to the static sieve pore plate 3 through the heat sealing frame 6 to carry out continuous heat sealing line, and the heat sealing of the outer packaging bag is carried out; after the two layers of films of the outer packaging bag 5 are sealed by heat sealing at intervals, the heat sealing cylinder 14 retracts to drive the heat sealing strips of the heat sealing machine on the heat sealing frame 6 to return to the high position above the static sieve pore plate 3; after the movable sieve plate 2 is quickly returned to be in butt joint with the outer packing box 4 and the opening end of the outer packing bag 5 is fully and tightly adsorbed by the passive sieve plate 2, the movable sieve plate 2 sucks the outer packing bag 5 out of the outer packing box 4 at a very slow speed, the movable sieve plate 2 is returned to be in butt joint with the outer packing box 4 again, and the movable sieve plate 2 transversely moves the outer packing bag 5 to the sieve hole surface of the static sieve plate 3 to be in butt joint with the sieve hole surface of the static sieve plate 3; in the process of transversely transferring the movable sieve plate to the static sieve plate, the side columns on the side wall of the movable sieve plate and the palm brushes at the lower ends of the side columns can sweep from the upper plane of the static sieve plate, blood bags with regular planes on the static sieve plate are swept out of the upper plane of the static sieve plate and pushed to a bag material box 15 outside the packaging machine; then, the regular blood bags are subjected to outer packing work repeatedly in the steps; after the first conveyor belt 10 conveys the blood bag to the second conveyor belt 8 through the bell mouth, the first conveyor belt 10 stops conveying the blood bag to the second conveyor belt 8; after the bag of blood has been packed and pushed into the magazine 15, the first conveyor belt 10 is put into operation again, until the next bag of blood is transported to the second conveyor belt 8 or the conveyor plate through the bell mouth, and the first conveyor belt 10 is put out of operation again.
The operation mode of the heat-seal cylinder 14 for sealing the bag adopts a manipulator 7 without fingertips, and when the heat-seal cylinder 14 for sealing the bag adopts a manipulator 19 with fingertips, the outer packaging bag 5 is heat-sealed and sealed by an interval heat-seal method: the heat sealing strips of the heat sealing machine on the heat sealing frame 6 on the heat sealing cylinder 14 right above the heat sealing strip grooves of the static sieve pore plate 3 are arranged into two upward grooves, and the two upward groove parts just cross over two fingers of a fingertip manipulator 19 to form spaced heat sealing; the upper convex surface of the groove is slightly lower than or equal to the upper plane of the static sieve plate; when two fingers and fingertips of the manipulator 19 are still in the external packaging bag 5 filled with the regular blood bag, the heat-sealing cylinder 14 pushes the heat-sealing strips on the heat-sealing machine to the static sieve plate 3 through the heat-sealing frame 6 and is butted with the heat-sealing strips on the heat-sealing strip grooves on the static sieve plate 3, after two layers of films of the external packaging bag 5 are sealed by heat-sealing and bonding at intervals, the heat-sealing cylinder 14 retracts, and the heat-sealing strips of the heat-sealing frame 6 on the heat-sealing cylinder 14 return to the high position above the static sieve plate 3; then the fingers and fingertips of the manipulator 19 are withdrawn from the outer packaging bag 5 with the sealed opening at intervals through the manipulator cylinder 12, so as to prevent the heat sealing machine from heat sealing all the pipelines on the blood bag.
The sieve mesh end far away with quiet orifice plate sets up to being less than quiet sieve mesh face horizontal position, and when the outer packing bag bottom was packed into to the blood bag, the blood bag can be in and be less than quiet sieve mesh face horizontal position of quiet orifice plate, prevents just to be pressed below the blood bag, and inherent one pipeline escape bleeding bag pushes down on the blood bag, and the free condition takes place before being heat-sealed to blood bag outer packing bag, in order to do benefit to going on of carrying out the heat seal process to blood bag outer packing bag simultaneously.
