[0002] An infusion bag is a bag used to hold infusion liquids. Commonly used are single-tube infusion bags and double-tube infusion bags. A single-tube infusion bag has only one tube opening, while a double-tube infusion bag has two tube openings side by side.

[0003] According to requirements, infusion bags must be inspected visually to ensure the liquid is free of fibers, color spots, foreign matter, or white lumps. Traditional inspection involves manually moving the product from the conveyor belt to an inspection table. One person holds the bag by the mouthpiece and the other by the hanging ring, slightly above the inspection table, and carefully inspects the bag visually.

[0004] With the increasing popularity of intelligent equipment, intelligent inspection machines are also gaining popularity. To achieve a more fully automated approach, robots are often used to transfer products from conveyor belts to the inspection table, where they are hung on the intelligent inspection machine's hanging port using the bag's tube. However, these robots are expensive, and the high cost significantly increases the burden on businesses.

[0005] To address this issue, our company designed a full-line conveyor that automatically transports infusion bags to a light inspection device. However, during operation, unexpected situations often occurred when transferring infusion bags from conventional conveyor belts to the full-line conveyor, such as the infusion bags failing to fit properly into the box of the full-line conveyor.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0055] like Figures 1-4 As shown, the bag hanging machine for infusion bag light inspection disclosed in this embodiment includes an infusion bag conveying device and an array conveying device arranged in sequence along the transmission direction. The array conveying device includes a conveyor belt mechanism 2 and a bag sorting mechanism 4. The conveyor belt mechanism 2 includes a motor and a second conveyor belt 21. At least one column of boxes 3 is provided on the second conveyor belt 21. Each column of boxes 3 is evenly arranged along the transmission direction. The arranged boxes 3 are used to receive the infusion soft bags 8 delivered by the infusion bag conveying device one by one.

[0056] like Figure 5 As shown, the infusion bag conveying device includes a first conveyor belt 1, the first conveyor belt 1 has at least one conveying channel, the number of conveying channels is equal to the number of columns of boxes 3 and corresponds one-to-one to each column of boxes 3, and the outlet of the first conveyor belt 1 is located above the inlet of the second conveyor belt 21.

[0057] Optionally, in some embodiments, the infusion bag conveying device further includes a bag pressing mechanism 5, comprising a pressure rod 51 disposed at the outlet end of the first conveyor belt 1. The pressure rod 51 corresponds one-to-one with each transmission channel and is located above the corresponding transmission channel. For a double-tube infusion bag, the pressure rod 51 can be positioned at the centerline of the transmission channel. During transportation, the two tube openings 81 are located on the left and right sides of the pressure rod 51, respectively. The pressure rod 51 also serves to guide and separate the two tube openings 81.

[0058] like Figure 6 、 Figure 7 As shown, the pressure rod 51 includes a straight section 511, and the straight section 511 is provided with a downwardly protruding arc-shaped convex portion 512, and the arc-shaped convex portion 512 is located at the exit of the first conveyor belt 1. In some embodiments, the straight section 511 is inclined downward from front to back.

[0059] Optionally, in some embodiments, a transition roller 6 is provided at the exit of the first conveyor belt 1. The transition roller 6 is rotatably connected to the frame, is perpendicular to the conveying direction of the first conveyor belt 1, is located between the first conveyor belt 1 and the box 3, is lower than the top surface of the first conveyor belt 1, and the pressure rod 51 is located above the transition roller 6. During operation, the infusion bag 8 moves backward under the action of inertia, passes through the transition roller 6, and falls into the box 3. The friction force of the infusion bag 8 causes the transition roller 6 to rotate, thereby reducing the friction between the infusion bag 8 and the transition roller 6.

[0060] The front end of the pressure rod 51 is connected to the gantry support 52. The first conveyor belt 1 passes under the crossbeam of the gantry support 52. The two legs of the gantry support 52 are fixed on the support. The height of the pressure rod 51 can be adjusted or not.

[0061] Optionally, in some embodiments, Figure 7 As shown, a connecting base 53 is mounted on the gantry support 52. The connecting base 53 has a vertical through-hole, in which a vertical rod 54 is mounted. The vertical rod 54 is locked to the connecting base 53 by a first fixing pin 55. Loosening the fixing pin 55 allows the vertical rod 54 to be moved up and down. The front end of the pressure rod 51 is fixedly connected to the vertical rod 54. The pressure rod 51 can be threadedly connected to the vertical rod 54 or manufactured integrally.

[0062] In some embodiments, there is a horizontal through hole on the vertical rod 54, and the front end of the pressure rod 51 is a horizontal section. The horizontal section is installed in the horizontal through hole and locked by a second fastening pin 56. By loosening the second fastening pin 56, the pressure rod 51 is moved forward and backward to adjust the front and rear position of the pressure rod 51.

[0063] Optionally, in some embodiments, Figure 5 As shown, the infusion bag conveying device also includes a bag sorting brush 7 mounted on the bracket. The brushes 7 correspond to each transfer channel and are located above the corresponding transfer channel. The width of the brush 7 matches the width of the transfer channel and the width of the infusion bag 8. The distance between the end of the bristles of the brush 7 and the top surface of the transfer channel is less than the thickness of the infusion bag 8 when it is in a collapsed state. The brush 7 can be used to smooth out curled infusion bags 8, facilitating subsequent boxing.

[0064] Optionally, in some embodiments, Figure 8 As shown, the bag sorting brush 7 is mounted on an adjustable mechanism, which includes a mounting base 71, a vertical rod 72, a crossbar 73, and a mounting block 74. The mounting base 71 is fixed to the frame. The vertical rod 72 passes through the through-hole of the mounting base 71 and is locked by a first locking pin 76. The mounting block 74 is fixed to the vertical rod 72. The crossbar 73 passes through the through-hole of the mounting block 74 and is locked by a second locking pin 75. The bag sorting brush 7 is mounted on the crossbar 73. Loosening the first locking pin 76 adjusts the height of the bag sorting brush 7 and crossbar 73; loosening the second locking pin 75 adjusts the left and right position of the bag sorting brush 7 and crossbar 73.

[0065] like Figure 10 As shown, the box 3 includes a vertical plate 31 and a side plate 32, and the left and right sides of the vertical plate 31 are respectively connected to the side plates 32. The vertical plate 31 and the side plates 32 on both sides form a three-sided structure, which is convenient for the infusion soft bag 8 to slide into the box 3 from the top.

[0066] In some embodiments, the tops of the side panels 32 and the tops of the vertical panels 31 are provided with outwardly inclined guide plates 34. The guide plates 34 facilitate guiding the infusion bag 8 into the box 3. To facilitate connection between the vertical panels 31 and the second conveyor belt 21, the bottoms of the vertical panels 31 are connected to horizontal plates 33 with mounting holes. The vertical panels 31 are fixedly connected to the second conveyor belt 21 via the horizontal plates 33 connected to their bottoms.

[0067] It is worth noting that the number of rows of boxes 3 can be appropriately set as needed. To improve transmission efficiency, at least two rows of boxes 3 are provided on the second conveyor belt 21. In some embodiments, the conveyor belt includes three rollers arranged in a triangular shape, and the second conveyor belt 21 is wound around the three rollers. The drive motor can be a stepper motor.

[0068] like Figure 9 、 Figure 11-13 As shown, the bag sorting mechanism 4 includes guide bars 41 arranged along the transport direction. At least two guide bars 41 are mounted above each row of boxes 3. A gap is formed between the guide bars 41 for the nozzles 81 of the infusion bags 8 to pass through. The nozzles 81 of the infusion bags 8 have a flange. To ensure that the flange of the nozzle 81 can be hooked, the distance between two corresponding guide bars 41 should be less than the outer diameter of the flange.

[0069] If it is a single-tube infusion bag, each row of boxes 3 is equipped with two guide bars 41; if it is a double-tube infusion bag, each row of boxes 3 is equipped with three guide bars 41, and the space between the two guide bars 41 is for one tube opening 81 to pass through. The distance between the guide bars 41 and the box 3 is reasonably set according to the specifications of the infusion bag. Taking the transportation of double-tube infusion bags as an example, there are three guide bars 41 arranged at equal intervals above each row of boxes 3, and the space between the two guide bars 41 is for two tube openings 81 to pass through, and the pressure rod 51 is directly opposite to the guide bar 41 in the middle position among the three guide bars 41. Figure 4 As shown, in particular, the rear end of the pressure rod 51 is connected to the guide bar 41 in the middle position, which has two beneficial effects: on the one hand, the rear end of the pressure rod 51 is fixed; on the other hand, the pressure rod 51 is made continuous with one of the guide bars 41, thereby achieving continuous guidance of the two pipe openings 81.

[0070] Optionally, in some embodiments, Figure 13As shown, in order to facilitate the tube mouth 81 of the infusion soft bag 8 to slide smoothly into between the two guide bars 41, the front end of the guide bar 41 has a guiding slope, and the guiding slope is located on the side facing the tube mouth; the guiding slopes of the two guide bars 41 are arranged relative to each other to form a flared portion 410, and the setting of the flared portion 410 is more conducive to the sliding in of the tube mouth 81.

[0071] Optionally, to facilitate the installation of the guide bar 41 , at least two gantries 42 are installed on the frame along the transmission direction, the second conveyor belt 21 passes under the gantries 42 , and the guide bar 41 is connected to the at least two gantries 42 respectively through connecting rods 44 .

[0072] The height of the guide bar 41 can be adjusted or not. There are two ways to achieve the height adjustment of the guide bar 41: Method 1, the lower end of the connecting rod 44 is vertically passed through the through hole of the crossbeam of the gantry 42 and connected to the guide bar 41. By lifting or moving the connecting rod 44 up or down, the guide bar 41 can be driven to move up and down, and the connecting rod 44 is locked to the gantry 42 by two locking nuts; Method 2, the connecting rod 44 is threadedly connected to the crossbeam of the gantry 42, and the lower end of the connecting rod 44 is rotatably connected to the guide bar 41. By rotating the connecting rod 44, the connecting rod 44 can be driven to spirally rise or fall, thereby driving the guide bar 41 to move up and down.

[0073] Because the guide strips have a certain length, in order to keep the guide strips parallel for a long time, in some embodiments, the bag sorting mechanism 4 further includes a distance component 43, such as Figure 15 As shown, the distance component 43 includes a crossbeam 431 and a foot 432 . The number of the foot 432 is equal to and corresponds to the number of the guide bars 41 . One end of the foot 432 is fixedly connected to the crossbeam 431 , and the other end of the foot 432 is fixedly connected to one of the guide bars 41 .

[0074] Optionally, in order to facilitate the infusion soft bag 8 to slide onto the light inspection device, in some embodiments, such as Figure 14 As shown, the guide bar 41 includes a horizontal section 411, an arcuate section 412, and an inclined section 413, which are connected in sequence from front to back. The length of the horizontal section 411 matches the length of the second conveyor belt 21, and the outlet end of the inclined section 413 is lower than the inlet end. The guide bar 41 may be manufactured integrally or not.

[0075] It is worth noting that it is best if the inclined section 413 is connected to a distance component 43 , and the distance component 43 of the inclined section 413 is connected to the nearest gantry 42 via a reinforcing bar 45 .

[0076] Taking the transport of double-tube infusion bags as an example, in some embodiments, the first conveyor belt 1 is divided into two transport channels by a divider bar 11. Two rows of boxes 3 are arranged on the second conveyor belt 21, each of which fits into one of the transport channels. Above each row of boxes 3 are three guide bars 41. Three gantries 42 and three distance components 43 are spaced apart along the transport direction. Each guide bar 41 is connected to each of the three gantries 42 via three connecting rods 44. Each distance component 43 has six feet 432, each of which is connected to one of the guide bars 41.

[0077] The method of using the infusion bag light inspection hanging bag machine in this application:

[0078] like Figure 16 、 Figure 17 As shown, the light inspection device 9 is placed at the rear end of the entire array of conveying devices. A plurality of hooks 91 are provided on the light inspection device 9 along the circumferential direction. For a single-tube infusion bag, the hook 91 has two fingers 92; for a double-tube infusion bag, the hook 91 has three fingers 92, and a gap is formed between each pair of fingers for the tube mouth 81 of the infusion bag 8 to slide into.

[0079] The rear end of the guide bar 41 is used for docking with the hook 91 on the light inspection device 9. The docking here can be a contact docking or a docking with a gap.

[0080] The infusion bag 8 is transported from front to back by the first conveyor belt 1. Under the action of inertia and gravity, the infusion bag 8 falls from the first conveyor belt 1 into the box 3 on the second conveyor belt 21. The nozzle 81 of the infusion bag 8 also slides between the guide bars 41 and the guide bars 41. Under the action of the second conveyor belt 21, the infusion bag 8 moves to the outlet end of the second conveyor belt 21.

[0081] As the second conveyor belt 21 reverses direction, the infusion bag 8 escapes from the box 3. Due to the flange on the nozzle 81, the infusion bag 8 continues to hang on the two guide bars 41. Under the action of inertia and gravity, the infusion bag 8 slides along the guide bars 41 toward the light inspection device 9 and hangs on the hook 91 of the light inspection device 9. The second conveyor belt 21 delivers the infusion bag 8 one by one at a certain frequency. The light inspection device 9 rotates circumferentially at an adapted frequency, thereby automatically hanging the infusion bag 8 one by one on the light inspection device 9. Through the cooperation of the first conveyor belt 1, the second conveyor belt 21 and the light inspection device 9, the bag hanging and light inspection are automatically completed.

[0082] Optionally, in some embodiments, a bag arrival detection device (not shown) is provided at the outlet of the infusion bag conveyor. Both the bag arrival detection device and the motor are connected to a control system. The bag arrival detection device can be an existing detection device such as an infrared detector, and its description is omitted here. When the bag arrival detection device detects the arrival of an infusion bag 8, it drives the motor of the second conveyor belt 21 to rotate by a certain angle, and accordingly, the light detection device 9 also rotates by a certain angle.

[0083] The above specific implementation methods further illustrate the purpose, technical solutions and beneficial effects of this application in detail. It should be understood that the above are only specific implementation methods of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
