Description

Technical Field

[0002] Large-volume injections, commonly known as large infusions, usually refer to sterile liquid preparations with a volume greater than or equal to 50 ml that are directly infused into the body by intravenous drip. Existing large-volume infusion packaging containers mainly include several commonly used types such as glass bottles, hard plastic bottles and infusion bags. Among them, upright infusion soft bags are widely used because they are easy to take and easy to quickly observe the information on their surface. After filling, the upright soft bags need to be transported through a conveyor line. During the transportation process, the upright soft bags need to be turned for transportation. At this time, the soft bags need to be converted from uniform horizontal transportation to longitudinal transportation in groups of two.

[0003] The current steering conveying method is to connect a high-speed conveyor belt to the tail of the horizontal conveyor belt, and connect a steering conveyor belt to the tail of the high-speed conveyor belt. By using the high-speed movement of the high-speed conveyor belt, two upright soft bags are conveyed to the steering conveyor belt at the same time, and then transported to the next link through the steering conveyor belt.

[0044] like Figure 3 and Figure 4 As shown, two second magnetic blocks 11 are installed on the bracket 1 at the input end of the second conveyor belt 3, and the second magnetic blocks 11 correspond to the first magnetic blocks 524. When the upright soft bag is pushed into the guide rail 31 by the clamp 52, the first magnetic block 524 will move to the second magnetic block 11, and the second magnetic block 11 will adsorb and fix the corresponding first magnetic block 524, so that the two clamping plates 521 rotate and separate from each other. At this time, the second conveyor belt 3 will transport the upright soft bag, thereby realizing the steering transportation of the upright soft bag.

[0045] like Figures 4 to 6 As shown, a winding disk 45 and a plurality of guide wheels 46 are rotatably connected to the bracket 1, and the winding disk 45 is connected to the slide 41 by a pull rope 47, and the pull rope 47 passes around each guide wheel 46 in turn; a gear 461 is coaxially connected to the winding disk 45, and a rack 48 extending along the length direction of the first conveyor belt 2 is meshed on the gear 461, and the rack 48 is slidably connected to the bracket 1 along its own length direction, and the rack 48 and the bracket 1 are jointly connected with a third spring 49; an inclined guide surface 431 is provided on the insertion rod 43, and a second push block 23 is installed on the positioning seat 21 located at an even-numbered position on the first conveyor belt 2.

[0047] The working principle of the present application is as follows: when the two upright soft bags on the first conveyor belt 2 move to the corresponding clamps 52, the first push block 22 will push the insertion rod 43 to move out of the slot 411, and then the first push block 22 will flip downward and be out of the insertion rod 43, the first spring 42 will drive the slide 41 to move toward the second conveyor belt 3, and the slide 41 will drive the clamp 52 to move toward the upright soft bag on the first conveyor belt 2; the upright soft bag will enter between the two clamps 521, and the two rotating The hinge of the movable rod 523 will be blocked by the upright soft bag, so that the two rotating rods 523 rotate and close and clamp the upright soft bag together, the two clamping plates 521 will also rotate and clamp the upright soft bag, and the two end plates 522 will fit each other and abut against the side of the upright soft bag facing the second conveyor belt 3, so that the upright soft bag is automatically and stably clamped in the clamp 52; then the clamp 52 will push the upright soft bag onto the second conveyor belt 3, so that the upright soft bags can be automatically loaded in groups of two.

[0048] The upright soft bag pushed onto the second conveyor belt 3 will be embedded in the guide rail 31, and the second magnetic block 11 will adsorb and fix the corresponding first magnetic block 524, so that the two clamping plates 521 rotate and separate from each other. At this time, the second conveyor belt 3 will transport the upright soft bag, and the upright soft bag will move forward stably under the limiting action of the guide rail 31 and the pressure plate 32.

[0049] Then the second push block 23 will push the rack 48 to move, the rack 48 will drive the gear 461 to rotate, and the gear 461 will drive the reel 45 to reel in the drawstring 47; then the second push block 23 will flip downward and disengage from the rack 48, and the drawstring 47 will pull the slide 41 to move and reset to the side of the first conveyor belt 2 away from the second conveyor belt 3, and the insertion rod 43 will rebound under the elastic force of the second spring 44 and be reinserted into the slot 411, so that the slide 41 is re-locked and fixed for subsequent loading of upright soft bags.
