Description

Technical Field

[0001] This utility model belongs to the field of peritoneal dialysis fluid production technology, and relates to the improvement of conveying equipment in peritoneal dialysis fluid bag production line, specifically an automatic flipping device for the lower bag of peritoneal dialysis fluid. Background Technology

[0002] In the peritoneal dialysis fluid production line, soft bag products transition from the unpacking machine to the bag unloading machine. After high-temperature sterilization and cooling, the soft bag film tends to stick to the sterilization tray. Inside the bag unloading machine, grippers on the tray grabbing platform grasp the sterilization tray and rotate it 180°, causing the soft bags to fall onto the wide conveyor belt below. The conveyor belt then intermittently transports the soft bags row by row out of the bag unloading machine, onto the transfer chain conveyor. The transfer chain conveyor then intermittently transports the soft bags to the lifting conveyor, and finally to the light inspection station for inspection. Because the soft bags on the lifting conveyor need to be rotated 180° so that the printed side is facing down for inspection at the light inspection station, a dedicated operator's post must be set up next to the lifting conveyor to handle the rotation of the soft bags. This increases production costs and the labor intensity for the operators is relatively high. If a robotic arm is used to flip the soft bag, the structure and control of the robotic arm are too complex. The complex structure of the robotic arm leads to a high failure rate, which increases the cost of maintenance and repair. In addition, the manufacturing cost of the robotic arm is also very high.

[0003] How to design an automatic bag-turning device for peritoneal dialysis fluid, which can automatically turn the soft bags conveyed from the bag unloading machine 180° during the conveying process and send them to the light inspection station for inspection, reducing manual operation, achieving a high degree of automation, and having a simple structure and low manufacturing cost, is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides an automatic bag-turning device for peritoneal dialysis fluid. During the transportation process, the soft bag products conveyed from the bag unloading machine can be automatically turned 180° and sent to the light inspection station for inspection. This reduces manual operation, has a high degree of automation, and features a simple structure and low manufacturing cost.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An automatic bag-turning device for peritoneal dialysis fluid is characterized by comprising a turning and conveying mechanism, a bag-turning slide plate, a transverse conveying mechanism, and a controller. The turning and conveying mechanism includes a turning chain belt, a turning transmission component, and a turning transmission motor mounted on a turning and conveying frame. The transverse conveying mechanism includes a transverse conveyor belt, a transverse transmission component, and a transverse transmission motor mounted on a transverse conveying frame. The top surface of the transverse conveyor belt is lower than the top surface of the turning chain belt, and the transverse conveyor belt is perpendicular to the conveying direction of the turning chain belt. An inclined bag-turning slide plate is mounted on the turning and conveying frame to connect the turning and conveying mechanism. The transverse conveying mechanism is configured such that the controller is connected to the control terminals of the flipping drive motor and the transverse drive motor respectively. The controller controls the flipping drive motor to operate intermittently, driving the flipping chain belt to rotate through the flipping drive component, and conveying the soft bag products on the top surface of the flipping chain belt to the flipping slide plate. After sliding down and flipping 180°, the soft bag products fall onto the top surface of the transverse conveyor belt. The controller also controls the transverse drive motor to operate continuously, driving the transverse conveyor belt to rotate through the transverse drive component, and conveying the soft bag products that have fallen onto the top surface of the transverse conveyor belt to the light inspection station.

[0007] Improvements to the above technical solution: The bag-turning slide plate is an L-shaped plate made of stainless steel plate, and stainless steel side plates are provided at both ends. The height of the bag-turning slide plate is less than the length of the soft bag product. The upper end of the bag-turning slide plate is lower than the top surface of the flipping chain plate, and the lower end of the bag-turning slide plate is higher than the top surface of the transverse conveyor belt.

[0008] A further improvement to the above technical solution: the longitudinal length of the top surface of the flip chain conveyor is greater than the length of one of the soft bag products, and the transverse width of the top surface of the flip chain conveyor can accommodate at least six soft bag products arranged side by side and longitudinally.

[0009] Further improvements to the above technical solution: There are at least 6 bag-turning sliding plates, which are arranged side by side at intervals.

[0010] Further improvements to the above technical solution: The upper end of the bag-turning slide plate is hinged to the flipping conveyor frame and fastened by an adjustable locking component to adjust the tilt angle of the bag-turning slide plate.

[0011] A further improvement to the above technical solution is made: infrared sensors are installed on the flipping transmission frames on both sides of the flipping chain belt, and the infrared sensors are connected to the controller.

[0012] Further improvements to the above technical solution: The flip-over conveyor frame includes 4 legs, and the lower ends of the 4 legs on the flip-over conveyor frame are all provided with height-adjustable feet. The transverse conveyor frame includes 4 legs, and the lower ends of the 4 legs on the transverse conveyor frame are provided with height-adjustable feet.

[0013] The advantages and positive effects of this utility model are:

[0014] 1. This utility model relates to an automatic bag-turning device for peritoneal dialysis fluid, comprising a turning and conveying mechanism, a bag-turning slide plate, a transverse conveying mechanism, and a controller. The bag-turning slide plate is inclinedly mounted on the turning and conveying frame to connect the turning and conveying mechanisms. This allows the soft bag products on the top surface of the turning conveyor belt to be transported onto the bag-turning slide plate. During the slide, the soft bag products automatically turn 180°, landing with the printed side facing up on the top surface of the transverse conveyor belt. When the soft bag products are transported to the light inspection station, they are easily inspected by testing personnel. This improves automation, reduces manual operation, and lowers labor costs.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings:

[0022] See Figures 1-4This utility model discloses an embodiment of an automatic bag-turning device for peritoneal dialysis fluid, comprising a turning and conveying mechanism, a bag-turning slide plate 2, a transverse conveying mechanism, and a controller. The turning and conveying mechanism includes a turning chain belt 1, a turning transmission component, and a turning transmission motor 7 mounted on a turning and conveying frame 9. The transverse conveying mechanism includes a transverse conveyor belt 3, a transverse transmission component, and a transverse transmission motor 5 mounted on a transverse conveying frame 10. The top surface of the transverse conveyor belt 3 is lower than the top surface of the turning chain belt 1, and the transverse conveyor belt 3 is perpendicular to the conveying direction of the turning chain belt 1. The bag-turning slide plate 2 is inclinedly mounted on the turning and conveying frame 9 to connect the turning and conveying mechanisms. The controller is connected to the control terminals of the turning transmission motor 7 and the transverse transmission motor 5, respectively. The controller controls the turning transmission motor 7 to operate intermittently, driving the turning chain belt 1 to rotate through the turning transmission component, conveying the soft bag product 8 on the top surface of the turning chain belt 1 to the bag-turning slide plate 2. The soft bag product 8 slides down and turns 180° before falling onto the top surface of the transverse conveyor belt 3. The controller is used to control the continuous operation of the transverse transmission motor 5, drive the transverse conveyor belt 3 to rotate through the transverse transmission component, and transport the soft bag products 8 that fall onto the top surface of the transverse conveyor belt 3 to the light inspection station.

[0023] Furthermore, the aforementioned bag-turning slide plate 2 is an L-shaped plate made of stainless steel plate, and stainless steel side plates are provided at both ends. The height of the bag-turning slide plate 2 is less than the length of the soft bag product 8. The upper end of the bag-turning slide plate 2 is lower than the top surface of the flipping chain plate 1, and the lower end of the bag-turning slide plate 2 is higher than the top surface of the transverse conveyor belt 3.

[0024] Furthermore, the longitudinal length of the top surface of the aforementioned flip chain plate 1 is greater than the length of one soft bag product 8, and the transverse width of the top surface of the flip chain plate 1 can accommodate at least 6 soft bag products 8 arranged side by side and longitudinally.

[0025] Furthermore, there are at least 6 of the aforementioned bag-turning sliding plates 2, which are arranged side by side at intervals. Figure 1 The embodiment shown has 8 bag-turning slide plates 2.

[0026] Furthermore, the upper end of the aforementioned bag-turning slide plate 2 is hinged to the flipping conveyor frame 9 and secured by an adjustable locking component to adjust the tilt angle of the bag-turning slide plate 2. The hinge connecting the upper end of the bag-turning slide plate 2 to the flipping conveyor frame 9 can use bolts as the hinge shaft, and the adjustable locking component can use nuts. Tightening the nuts secures the plate, while loosening them adjusts the tilt angle of the bag-turning slide plate 2. In this way, the appropriate tilt angle of the bag-turning slide plate 2 can be adjusted according to the different heights of the soft bag products 8, ensuring that the soft bag products 8 land on the top surface of the transverse conveyor belt 3 after sliding and flipping 180°.

[0027] To ensure the normal transport of the soft bag products 8 and prevent their accumulation on the top surface of the flipping conveyor belt 1, this invention can also install infrared sensors on the flipping transmission frames on both sides of the flipping conveyor belt. These infrared sensors are connected to the controller. The controller controls the flipping drive motor 7 and the transfer mechanism 11 to operate synchronously, delivering the first row of soft bag products 8 from the top surface of the flipping conveyor belt 1 to the flipping slide plate 2. During the slide, the soft bag products 8 automatically flip 180° and fall onto the transverse conveyor belt 3. Meanwhile, the second row of soft-bag products 8 is conveyed to the top surface of the flipping conveyor belt 1 by the transfer mechanism 11. When the second row of soft-bag products 8 blocks the light emitted by the infrared sensor, the controller receives the blocking signal from the infrared sensor and controls the flipping drive motor 7 and the transfer mechanism 11 to stop running for a period of time. During this period, the first row of soft-bag products 8 is just conveyed to the light inspection station by the transverse conveyor belt 3, leaving space for the second row of soft-bag products 8 to slide down. Then, the controller controls the flipping drive motor 7 and the transfer mechanism 11 to start and run synchronously, sending the second row of soft-bag products 8 from the top surface of the flipping conveyor belt 1 to the flipping slide plate 2. The soft-bag products 8 automatically flip 180° during the sliding process and fall onto the transverse conveyor belt 3. At the same time, the transfer mechanism 11 conveys the third row of soft-bag products 8 to the top surface of the flipping conveyor belt 1. The above operating mode is repeated continuously.

[0028] Specifically: the aforementioned flipping conveyor frame 9 includes four legs, each with a height-adjustable foot at its lower end; the transverse conveyor frame 10 also includes four legs, each with a height-adjustable foot at its lower end. This facilitates adjustment of the height difference between the top surface of the flipping chain belt 1 and the top surface of the transverse conveyor belt 3, and allows for adjustment of the tilt angle of the bag-turning slide plate 2.

[0029] The method of using the automatic turning device for the lower bag of peritoneal dialysis fluid of this utility model is as follows: See Figures 1-4Inside the unloading machine, the sterilization tray is gripped by claws on the gripping platform and rotated 180°, causing the soft bag products to fall onto the wide conveyor belt below. The wide conveyor belt then intermittently transports the soft bag products row by row out of the unloading machine and onto the transfer chain plate of the transfer transmission mechanism 11. Then, the transfer chain plate and the flipping chain plate 1 operate synchronously, intermittently transporting rows of soft bag products 8 to the top surface of the flipping chain plate 1 of the flipping transmission mechanism in this utility model. Only one row of soft bag products 8 can be placed on the top surface of the flipping chain plate 1 at a time. When the flipping chain plate 1 is running, it transports the row of soft bag products 8 on its top surface to the bag-turning slide plate 2. The soft bag products 8 automatically rotate 180° during the sliding process, and when they fall onto the top surface of the transverse conveyor belt 3, the printed side faces upwards. The running transverse conveyor belt 3 then transports the soft bag products 8 to the light inspection station for easy light inspection by the inspection personnel. When the flipping conveyor belt 1 transports a row of soft bag products 8 from its top surface to the flipping slide plate 2, the transfer conveyor belt transports the next row of soft bag products 8 to the top surface of the flipping conveyor belt 1. Then, after pausing for a few seconds, the above steps are repeated.

[0030] The above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
