Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automatic packaging of infusion sets, in particular to a device for realizing posture adjustment and gathering. BACKGROUND

[0002] A disposable infusion set is a common medical consumable used for intravenous infusion. The disposable infusion set is usually composed of a venous needle, a needle cap, an infusion hose, a liquid filter, a flow rate regulator, a drip bottle, a bottle plug piercer, an air tube, and an air filter. The overall length of the disposable infusion set is relatively long. The disposable infusion set needs to be wound and packaged with a packaging bag when it is delivered from the factory. The manual winding and packaging of the disposable infusion set into the packaging bag has the problems of low efficiency and high cost. Some automatic devices on the market can replace manual operation to realize automatic winding and packaging of the disposable infusion set into the packaging bag.

[0003] The existing automatic winding and packaging device mainly includes a taking device, a winding device, a transferring device, a bag feeding device, a bag opening device, and a packaging bag sealing device. A disposable infusion set to be processed is clamped and moved by the taking device to the winding device, and then the winding device winds the disposable infusion set into a roll shape. Then, the bag opening device opens the inlet of the packaging bag, and the transferring device transfers the roll-shaped disposable infusion set to the bag opening device. Then, the bag feeding device feeds the roll-shaped disposable infusion set into the packaging bag, and finally the packaging bag sealing device seals the packaging bag. The specific structure of the existing automatic winding and packaging device can be referred to the invention patent application with the application publication number CN111348279A and the name of infusion set automatic taking, winding, and packaging device.

[0004] However, the transferring device for transferring the roll-shaped disposable infusion set to the bag opening device or the inlet of the packaging bag adopts two sets of clamping jaws to clamp and translate the roll-shaped disposable infusion set. During the translation of the two sets of clamping jaws with the roll-shaped disposable infusion set, the two sets of clamping jaws pass through the first transmission through hole of the bag feeding transition mold and the second transmission through hole of the bag feeding mold in sequence. During the translation of the two sets of clamping jaws with the roll-shaped disposable infusion set, the roll-shaped disposable infusion set is located on the horizontal plane. Since the pose of the air tube in the roll-shaped disposable infusion set processed by the winding device is not fixed but random, the roll-shaped disposable infusion set cannot smoothly enter the bag feeding transition mold and the bag feeding mold, and the roll-shaped disposable infusion set cannot be smoothly fed into the packaging bag at the subsequent station. The reliability of the entire roll-shaped disposable infusion set being fed into the packaging bag needs to be improved. In addition, the bag feeding transition mold is a rectangular structure. The roll-shaped disposable infusion set is relatively loose when passing through the internal space of the bag feeding transition mold with the two sets of clamping jaws. The width of the entire roll-shaped disposable infusion set is relatively large (i.e. the distance between the left and right sides of the entire roll-shaped disposable infusion set is relatively large), which is not conducive to the subsequent reliable feeding into the packaging bag. SUMMARY

DETAILED DESCRIPTION

[0058] The application will be further described in detail below with reference to the accompanying drawings.

[0059] The specific embodiments described below are merely preferred embodiments of the application and the scope of protection of the application is not limited thereto. Based on or according to the principles, concepts and spirits of the application, some changes or modifications can be made by those skilled in the art, and the technical solutions formed by these changes or modifications should be covered within the scope of protection of the application.

[0060] For the automatic winding packaging equipment for infusion devices, the air tube posture adjusting device can adjust the posture of the air tube of one infusion device to be processed. As shown in Figures 1-3As shown, the trachea posture adjustment device includes a support plate 1, a slide rail 2, a slider 3, a connecting block 4, a connecting plate 5, a finger cylinder 6, a left clamp 7, a right clamp 8, a left limit plate 9, a right limit plate 10, a cylinder bracket 11, and a cylinder 12. The slide rail 2 is fixedly mounted on the support plate 1, the slider 3 is connected to the slide rail 2, the connecting block 4 is fixedly mounted on the slider 3, the connecting plate 5 is fixedly connected to the connecting block 4, the finger cylinder 6 is fixedly mounted on the connecting plate 5, the finger cylinder 6 is provided with a left finger 6-1 and a right finger 6-2, the left clamp 7 is connected to the left finger 6-1, the right clamp 8 is connected to the right finger 6-2, the left limit plate 9 is connected to the left clamp 7, the right limit plate 10 is connected to the right clamp 8, the cylinder bracket 11 is fixedly mounted on the support plate 1, the cylinder 12 is mounted on the cylinder bracket 11, and the telescopic rod of the cylinder 12 is connected to the connecting block 4. The finger cylinder 6 is located in the vertical direction, and the left clamping jaw 7 and the right clamping jaw 8 are located in the vertical direction. The opening and closing of the left finger 6-1 and the right finger 6-2 of the finger cylinder 6 can drive the opening and closing of the left clamping jaw 7 and the right clamping jaw 8; Figures 1-3 The left finger 6-1 and the right finger 6-2 are in a closed state, the left clamp 7 and the right clamp 8 are in a closed state, and the left limit plate 9 and the right limit plate 10 are in a closed state. Figures 4-6 As shown, when the left finger 6-1 and the right finger 6-2 of the finger cylinder 6 are opened, the left clamp 7 and the right clamp 8 are in the open state, and the left limit plate 9 and the right limit plate 10 are also in the open state; it can be seen from the figure that the left clamp 7 is provided with a left arc groove 7-1, and the right clamp 8 is provided with a right arc groove 8-1, and the left arc groove 7-1 and the right arc groove 8-1 relatively form a clamping part for the hose. Those skilled in the art can understand that the clamping part of this specific structure is only a specific structural choice; it can be seen from the figure that the finger cylinder 6 is Y-type, and the left finger 6-1 and the right finger 6-2 are opened at a certain angle. It should be noted that the selection of the Y-type finger cylinder is only a better specific choice. The finger structure of the finger cylinder 6 can also be other structures such as parallel running fingers.

[0061] like Figure 7 As shown, the infusion set 13 includes a hose 13-1, a drip pot 13-2, a bottle stopper piercer 13-3, a flow rate regulator 13-4, and an trachea 13-5. When the left clamp 7 and the right clamp 8 are closed, the hose 13-1 of the infusion set can be clamped, for example, the portion of the hose 13-1 near the trachea 13-5 can be clamped. Figure 8 Middle (b) and Figure 9As shown, when the left and right clamping jaws 7 and 8 are closed, the left and right arc-shaped grooves 7-1 and 8-1 clamp the part of the hose 13-1 close to the air tube 13-5, and the left limiting plate 9 presses the air tube 13-5 downward so as to bend the air tube 13-5 downward. Under the action of the left limiting plate 9, the air tube 13-5 is arranged downward as a whole, avoiding the air tube 13-5 being arranged on a substantially horizontal plane or being arranged upward. As shown in the figure, the rear end of the left limiting plate 9 is connected with the left clamping jaw 7, and the left limiting plate 9 is arc-shaped as a whole, and the height H of the edge of the left limiting plate 9 gradually increases from the rear end to the front end (as shown in the figure). Figure 25 As shown, the left limiting plate 9 is arc-shaped as a whole, and the height H of the edge of the left limiting plate 9 gradually increases from the rear end to the front end. The shape is a preferred shape, but the specific shape of the left limiting plate 9 is not limited thereto, and can also be other shapes capable of pressing the air tube 13-5 downward. When the left and right clamping jaws 7 and 8 are closed to clamp the hose, there is a case that the right limiting plate 10 presses the air tube so as to arrange the air tube downward as a whole, that is, whether the right limiting plate 10 or the left limiting plate 9 acts depends on the position of the air tube before the left limiting plate 9 or the right limiting plate 10 acts.

[0062] The structure of the right limiting plate 10 is the same as that of the left limiting plate 9.

[0063] As shown, the left limiting plate 16 is planar as a whole, and the right limiting plate 17 is the same as the left limiting plate 16 in shape. Figures 26-29 As shown, the left limiting plate 16 is planar as a whole, and the right limiting plate 17 is the same as the left limiting plate 16 in shape. Figures 26-29 As shown, the left limiting plate 16 is planar as a whole, and the right limiting plate 17 is the same as the left limiting plate 16 in shape. Figure 30 , 31 As shown, the left limiting plate 16 is planar as a whole, and the right limiting plate 17 is the same as the left limiting plate 16 in shape. Figure 32 As shown, the left limiting plate 16 is planar as a whole, and the right limiting plate 17 is the same as the left limiting plate 16 in shape.

[0064] As shown, the left limiting plate 16 is planar as a whole, and the right limiting plate 17 is the same as the left limiting plate 16 in shape. Figure 33 and 34 As shown, the left limiting plate 16 is planar as a whole, and the right limiting plate 17 is the same as the left limiting plate 16 in shape. Figure 34 As shown, the left limiting plate 16 is planar as a whole, and the right limiting plate 17 is the same as the left limiting plate 16 in shape.

[0065] As shown, the left limiting plate 16 is planar as a whole, and the right limiting plate 17 is the same as the left limiting plate 16 in shape.

[0066] Before the tracheal posture adjustment device works, the infusion set is straightened, and the device for achieving the straightening function can be a commonly used device in the prior art (such as the related device disclosed in the invention patent application with application publication number CN118545341A). Figure 8 In the middle figure (a), the starting position of the left clamp 7 and the right clamp 8 before moving is the position in front of the drip pot 13-2 on the hose. The left clamp 7 and the right clamp 8 are closed at this position. At this time, the left limit plate 9 or the right limit plate 10 does not contact the trachea 13-5; then the cylinder 12 is started, and the telescopic rod of the starting cylinder 12 is extended to move the finger cylinder 6 forward, and the finger cylinder 6 moves the left clamp 7 and the right clamp 8 forward, the infusion set is stationary, the left clamp 7 and the right clamp 8 slide along the hose of the infusion set, and the left limit plate 9 and the right limit plate 10 move forward. When the left limit plate 9 and the right limit plate 10 move to the position of the trachea 13-5, the left limit plate 9 presses down on the trachea 13-5 so that the trachea 13-5 is arranged downward as a whole, as shown in FIG. Figure 8 Middle (b) and Figure 9 As shown, the posture adjustment of the trachea 13-5 is completed.

[0067] After the posture of trachea 13-5 is adjusted, the material taking device moves the entire infusion set to a position close to the winding device, specifically to the top of the winding device. When the material taking device moves, the trachea posture adjusting device also moves therewith.

[0068] like Figure 10 and 11 As shown, the winding device adopts a common structure in the prior art. The winding device 14 may include a rotary drive motor 14-1, a turntable 14-2, a winding column 14-3, and a hose clamping mechanism 14-4. The turntable 14-2 is connected to the output shaft of the rotary drive motor 14-1, the four winding columns 14-3 are connected to the turntable 14-2, and the hose clamping mechanism 14-4 is installed on the edge of the turntable 14-2.

[0069] When the material taking device, the left clamping jaw 7 and the right clamping jaw 8 move with the infusion device to the top of the winding device, the entire material taking device moves downward, the trachea posture adjustment device also moves downward, and the infusion device hose moves downward to the clamping mechanism 14-4. At this time, since the trachea 13-5 is arranged downward and the clamping mechanism 14-4 is located at the edge of the entire winding device, the trachea 13-5 will be located at the edge of the turntable 14-2 (such as Figure 12As shown), the hose clamping mechanism 14-4 is actuated to clamp the hose of the infusion set (the trachea is still arranged downward at this time), and then the left clamping jaw 7 and the right clamping jaw 8 are opened, the trachea posture adjustment device is withdrawn, the material taking device releases the infusion set and withdraws, and then the rotary drive motor 14-1 is operated to rotate the turntable 14-2, and the four winding columns 14-3 rotate with the rotation of the turntable 14-2, thereby winding the entire infusion set into several turns, and finally forming a roll, as shown in FIG. Figure 12 After the entire infusion set is wound into a roll, the rotary drive motor 14-1 stops, and the hose clamping mechanism 14-4 releases the hose.

[0070] Next, the transfer device takes away the rolled infusion set. The specific process can be: the two sets of clamps of the transfer device clamp the front part and the back part of the rolled infusion set respectively. Figure 12 The roll-shaped infusion set can be divided into an upper portion, a lower portion, a left portion, and a right portion. The upper portion is the front portion, and the lower portion is the back portion. The two sets of jaws of the transfer device then move upward, lifting the roll-shaped infusion set, freeing it from the winding device. The infusion set's air tube now hangs naturally downward.

[0071] Next, the transfer device moves forward, refer to Figure 13 , that is, the transfer device moves toward the gathering device 15 in the direction of the arrow in the figure.

[0072] like Figures 14-20 As shown, the gathering device 15 includes a base 15-1, a left column 15-2, a right column 15-3, a hollow gathering block 15-4, a left guide plate 15-5, a right guide plate 15-6, a trachea guide rod 15-7, and a trachea guide rod bracket 15-8. The left column 15-2 and the right column 15-3 are respectively fixedly connected to the base 15-1, the upper ends of the left column 15-2 and the upper ends of the right column 15-3 are respectively fixedly connected to the hollow gathering block 15-4, the left guide plate 15-5 is fixedly connected to the hollow gathering block 15-4, and the left guide plate 15-5 is fixedly connected to the hollow gathering block 15-4. The left side of the hollow collecting block 15-4 is connected, the right guide plate 15-6 is connected to the right side of the hollow collecting block 15-4, the trachea guide rod bracket 15-8 is fixedly connected to the right column 15-3, the trachea guide rod 15-7 is connected to the trachea guide rod bracket 15-8, the hollow collecting block 15-4 is provided with a central through hole 15-4-1 whose inner diameter gradually decreases from front to back, the top of the hollow collecting block 15-4 is provided with an aisle 15-4-2, and the aisle 15-4-2 is connected to the central through hole 15-4-1. The rear end of the trachea guide rod 15-7 extends into the central through hole 15-4-1 of the hollow collecting block 15-4. In the vertical direction, the front end of the trachea guide rod 15-7 is lower than the rear end of the trachea guide rod 15-7; refer to Figure 21, the included angle between the tracheal guide rod 15-7 and the longitudinal section of the hollow gathering block 15-4 is α, 0° < α < 90°, the further preferred value range of the included angle α is: 20° < α < 60°, and the further preferred value range is: 25° < α < 40°; for the rear end of the tracheal guide rod 15-7 extending into the center through hole 15-4-1 of the hollow gathering block 15-4, the figure shows that the rear end of the tracheal guide rod 15-7 is close to the left inner wall of the center through hole 15-4-1, and this position structure is only a preferred choice. The right guide plate 15-6 is provided with an arc-shaped guide concave surface 15-6-1, and it should be noted that the preferred technical means of arranging the left guide plate 15-5 and the right guide plate 15-6 is that the inner side of the left guide plate 15-5 can guide the roll-shaped infusion device to the center through hole 15-4-1, and the arc-shaped guide concave surface 15-6-1 of the right guide plate 15-6 can guide the roll-shaped infusion device to the center through hole 15-4-1, and the left guide plate 15-5 and the right guide plate 15-6 are used at the same time to form a flared structure; those skilled in the art can understand that the left guide plate 15-5 and the right guide plate 15-6 can not be arranged.

[0073] It should be noted that for the rear end of the tracheal guide rod 15-7 extending into the center through hole 15-4-1 of the hollow gathering block 15-4, refer to Figure 22 , the rear end of the tracheal guide rod 15-7 can also be close to the right inner wall of the center through hole 15-4-1.

[0074] Refer to Figure 13 , the transfer device moves the roll-shaped infusion device to the gathering device 15 in the horizontal plane, since the trachea of the roll-shaped infusion device is in a natural downward state, the trachea will contact and slide along the tracheal guide rod 15-7, as Figure 23As shown, as the roll-shaped infusion device moves towards the center through hole 15-4-1 of the hollow gathering block 15-4, the air tube gradually approaches the body of the roll-shaped infusion device, and finally the air tube approaches the body of the roll-shaped infusion device in a substantially horizontal posture, and the air tube smoothly enters the center through hole 15-4-1, and then the entire roll-shaped infusion device is gathered in the center through hole 15-4-1, and the width of the entire roll-shaped infusion device becomes smaller (i.e. the distance between the left and right sides of the entire roll-shaped infusion device becomes smaller); during the gathering of the entire roll-shaped infusion device in the center through hole 15-4-1, the two groups of clamping jaws of the transfer device pass through the passageway 15-4-2. The air tube guide rod 15-7 can also adjust the position of the air tube of the roll-shaped infusion device, so that the pose of the air tube of the entire roll-shaped infusion device output from the center through hole 15-4-1 is substantially fixed, thereby facilitating the subsequent entry of the entire roll-shaped infusion device into the package more conveniently and smoothly. Finally, the entire roll-shaped infusion device output from the center through hole 15-4-1 enters the bagging station, and at this time the entire roll-shaped infusion device can be smoothly and reliably packed into the packaging bag. The pose of the air tube of the entire roll-shaped infusion device output from the center through hole 15-4-1 is as shown in Figure 24 Figure 24 The arrow direction is the forward translation direction of the entire roll-shaped infusion device, and it can be seen that the air tube 13-5 is distributed backward, so that the entire roll-shaped infusion device can more conveniently and smoothly enter the packaging bag. In addition, the air tube of each roll-shaped infusion device formed by continuous batch operation is distributed backward, that is, the position of the air tube distribution of each roll-shaped infusion device is consistent, so that the position of the air tube distribution is consistent after the final roll-shaped infusion device is packed into the packaging bag.

[0075] In some cases, the width of the roll-shaped infusion device waiting for gathering processing is large, so before entering the center through hole 15-4-1 of the hollow gathering block 15-4, the left side of the roll-shaped infusion device first contacts the left guide plate 15-5 to be guided to the front entrance direction of the center through hole 15-4-1, or the right side of the roll-shaped infusion device first contacts the arc-shaped guide concave surface 15-6-1 of the right guide plate 15-6 to be guided to the front entrance direction of the center through hole 15-4-1, or the left guide plate 15-5 and the right guide plate 15-6 act simultaneously.

[0076] Under the action of the air tube guide rod 15-7, the entire roll-shaped infusion device can be reliably and smoothly transferred, and the transfer effect is improved; it is also beneficial to the gathering operation of the entire roll-shaped infusion device in the hollow gathering block 15-4.​
