[0002] With the diversification of infusion product packaging forms in the market, the infusion market currently mainly includes plastic bottles / stand-up bags, glass bottles, plastic ampoules, soft bags, etc. Among the many packaging forms, plastic bottles (stand-up bags) account for the largest proportion. Among large-scale (above 1000ml) infusion products, soft bag packaging accounts for a relatively high proportion, especially in the peritoneal dialysis products and surgical wound irrigation products developed in recent years, which basically adopt the soft bag packaging form.

[0003] The production of large-sized soft bag infusion products has the following difficulties: product leakage control, product transportation and handling, and product packaging. Among them, due to the heavy weight and soft nature of the product, it is not as easy to achieve transportation and diversion as hard products.

[0004] When a new workshop is built, product conveying design will be carried out according to process requirements. However, the use of conveyor belt conveying will often take up a lot of workshop layout space, which is not conducive to the rational use of space and the aesthetics of the workshop.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] Example 1

[0046] like Figure 1 As shown, this embodiment provides a reversing device suitable for large-sized infusion bags, including a mounting top plate 4 connected to the top of a mechanism bracket 14, a rotating structure connected to the mounting top plate 4, a lifting structure connected to the rotating structure, and a clamping structure connected to the bottom end of the lifting structure.

[0047] Specifically, the rotating structure includes a mounting base 2 connected to a mounting top plate 4, a rotary cylinder 1 is connected to the mounting base 2, a rotating shaft 6 is connected to the rotary cylinder 1, the rotating shaft 6 passes through the mounting top plate 4, and is connected to a plane bearing 3 above the mounting top plate 4, and is connected to a seated self-aligning bearing 5 below the mounting top plate 4.

[0048] When the transport direction of the material 29 needs to be adjusted, the rotary cylinder 1 is rotated to adjust the angle, so that the direction of the material 29 can be adjusted, thereby achieving the effect of adjusting the material 29 in multiple directions.

[0049] Specifically, the clamping structure includes a clamping cylinder 11 connected to the lifting structure through an upper connecting plate 9, the lower end of the clamping cylinder 11 is connected to a lower connecting plate 13, and two symmetrically arranged hooks 12 are hinged on the lower connecting plate 13. A pull rod plate 10 is hinged between each pull hook 12 and the upper connecting plate 9, and one end of the pull rod plate 10 is hinged to the upper connecting plate 9, and the other end is hinged to the pull hook 12.

[0050] The main function of the clamping structure is to clamp and lift the material 29 transported to the phase-changing device, and to cooperate with the rotating structure to adjust the direction of the material 29.

[0051] Specifically, the lifting structure includes upper and lower cylinders 8 , and the tops of the upper and lower cylinders 8 are connected to the rotating shaft 6 through a fixing plate 7 .

[0052] The main functions of the lifting structure are, on the one hand, to lift the material 29 after clamping the material 29 , and on the other hand, to move the clamping structure downward to clamp new material 29 after transferring the material 29 to a designated position.

[0053] The working principle of the reversing device is as follows: after the material 29 is transported to the bottom of the reversing device 28, the upper and lower cylinders 8 drive the clamping structure to move downward, so that the material 29 is located between the two hooks 12, and then the clamping cylinder 11 is started, and the hook 12 is clamped by the clamping cylinder 11. The clamped material 29 is lifted up by the upper and lower cylinders 8, and then the angle is adjusted by the rotation of the rotary cylinder 1, and then the angle of the clamped material 29 is adjusted, and the upper and lower cylinders 8 move the material 29 downward, and finally the clamping cylinder 11 releases the material 29, completing the reversal of the material 29. After the reversal is completed, the upper and lower cylinders 8 are lifted up, and the rotary cylinder 1 restores the upper and lower cylinders 8 and the clamping cylinder 11 to their original positions, and performs reversal transfer of the next material 29.

[0054] Example 2

[0055] like Figure 2 As shown, this embodiment provides a reversing device suitable for large-sized infusion bags. Compared with Example 1, the difference of the reversing device 28 of this embodiment is that the structure of the hook 12 is composed of a first hook plate 15 and a second hook plate 16, and the connection angle between the first hook plate 15 and the second hook plate 16 is 95°.

[0056] For example, the connection angle between the first hook plate 15 and the second hook plate 16 may also be 90°, 100°, etc., and may also be specifically designed according to the size and shape of the material 29 to be clamped and supported.

[0057] Specifically, the first hook plate 15 and the second hook plate 16 are an integrally formed structure; an arc-shaped supporting bottom 17 is provided at the bottom of the second hook plate 16 .

[0058] Compared with Example 1, the advantage of this embodiment is that the first hook plate 15 and the second hook plate 16 are set to a structure with a certain angle, which can improve the stability of the material 29 clamping. At the same time, an arc-shaped support bottom 17 is set at the bottom of the second hook plate 16 to prevent the material 29 from slipping during the turning process. The combination of the two makes the material 29 very stable during the turning process.

[0059] Example 3

[0060] like Figure 3 As shown, this embodiment provides a control system for the reversing device 28 of Embodiment 1 and Embodiment 2, wherein the hardware includes a host control box 19, a PLC controller 25, and a solenoid valve island assembly 26 and a sensor unit connected by electrical cables.

[0061] The host control box 19 includes a start button 21 , a stop button 22 , a human-machine interface 24 , a power indicator light 20 and an emergency stop button 23 .

[0062] The PLC controller 25 includes a CPU module, an I / O unit, and a communication unit.

[0063] The solenoid valve island group 26 includes a rotary solenoid valve, an up and down solenoid valve and a gripper solenoid valve.

[0064] The PLC controller 25 and the solenoid valve island group 26 are installed in the main engine control box 19.

[0065] The sensor unit includes a capacitive sensor 27 for material 29 detection and a cylinder state detection (magnetic switch).

[0066] The electrical system includes power circuit breakers, switching power supplies, axial fans, communication wires, terminal blocks, etc.

[0067] The control principle of the control system is:

[0068] S1: The material 29 (product) moves to the right under the drive of the conveyor and is detected by the "capacitive sensor 27";

[0069] S2: The PLC controller 25 triggers a delay (the delay time will be set on the human-machine interface 24). After the delay time is reached, the program controls the "up and down" solenoid valve to act, and the upper and lower cylinders 8 "go down";

[0070] S3: After the upper and lower cylinders 8 are “down” in place and the detection sensor is triggered, the program controls the “gripping hand” solenoid valve to actuate, and the gripping hand cylinder 11 “clamps”;

[0071] S4: After the hand-gripping cylinder 11 is “clamped” in place, the detection sensor is triggered, and the program controls the “up and down” solenoid valve to release, and the upper and lower cylinders 8 “go up”;

[0072] S5: After the upper and lower cylinders 8 are “up” in position detection sensors are triggered, the program controls the “rotation” solenoid valve to operate, and the rotary cylinder 1 “rotates”;

[0073] S6: After the rotary cylinder 1 is “rotated” to the position detection sensor and is triggered, the program controls the “gripping” solenoid valve to release the gripping cylinder 11;

[0074] S7: After the gripper cylinder 11 is “loose” into position detection sensor is triggered, the program controls the “rotation” solenoid valve to operate, and the rotary cylinder returns 1 time.

[0075] The program repeatedly executes the above process to achieve the reversal of continuous large-size products on the production line.

[0076] Program Description:

[0077] 1. PLC is selected as the main control, which is convenient for program monitoring and optimization. With the help of human-machine interface 24, parameter setting and action monitoring can be realized quickly;

[0078] 2. Adopt the control principle of logical "steps" and strictly follow the above action flow to switch between "steps" to ensure the safe operation of the equipment;

[0079] 3. On the human-machine interface 24, the automatic operation and manual operation interfaces are designed with separate pages and are electrically interlocked to ensure the safety of operators.

[0080] The control system is a complete automatic closed-loop control system. Each sensor can detect whether each action of the mechanism is in place. If a fault occurs, it can promptly alarm on the human-machine interface 24 and emit a buzzer alarm. The time beat of each action can be quickly set and monitored through the human-machine interface 24 to ensure that the products are placed stably. The system can also count products and calculate the pass rate to ensure the reliability of product data. The equipment is simple, the investment cost is low, the failure rate is low, and the speed can reach 30 bags / minute.

[0081] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model.
