Description

Technical Field

[0001] The invention relates to the technical field of automatic packaging of infusion sets, and in particular to a device for realizing posture adjustment and folding. Background Art

[0002] Disposable infusion sets are a common medical consumable used for intravenous infusion. Disposable infusion sets usually consist of nine parts: intravenous needle, needle cap, infusion hose, liquid medicine filter, flow rate regulator, drip pot, bottle stopper puncture device, trachea, and air filter. The overall length of disposable infusion sets is relatively long. Disposable infusion sets need to be wrapped and packaged in packaging bags before leaving the factory. Manually wrapping and packing disposable infusion sets into packaging bags is inefficient and costly. There are some automated equipment on the market that can replace manual winding and packaging operations.

[0003] The existing automatic wrapping packaging equipment mainly includes a material taking device, a wrapping device, a transfer device, a bag feeding device, a bag opening device, and a packaging bag sealing device. An infusion set to be processed is clamped by the material taking device and moved to the wrapping device, and then the wrapping device wraps the infusion set into a roll, and then the bag opening device opens the entrance of the packaging bag, and then the transfer device transfers the rolled infusion set to the bag opening device, and then the bag feeding device sends the rolled infusion set into the packaging bag, and finally the packaging bag sealing device seals the packaging bag. The specific structure of the existing automatic wrapping packaging equipment can refer to the invention patent application with application publication number CN111348279A and the name of the automatic material taking, wrapping and bagging device for infusion sets.

[0004] However, the transfer device for transferring the roll infusion device to the bag opening device or the entrance of the packaging bag adopts two sets of clamps to clamp the roll infusion device and translate it. During the translation process of the roll infusion device with the two sets of clamps, the two sets of clamps pass through the first transmission through hole of the bag entry transition mold and the second transmission through hole of the bag entry mold in sequence; during the translation process of the roll infusion device with the two sets of clamps, the roll infusion device is located in the horizontal plane. Since the position of the trachea in the roll infusion device processed by the winding device is not fixed but random, the roll infusion device cannot smoothly enter the bag entry transition mold and the bag entry mold, and the roll infusion device cannot be smoothly loaded into the packaging bag at the subsequent workstation. The reliability of the entire roll infusion device being loaded into the packaging bag needs to be improved. In addition, the bag entry transition mold is a rectangular structure. The two sets of clamps carry the roll infusion device through the internal space of the bag entry transition mold. The roll infusion device is relatively loose, and the width of the entire roll infusion device is large (that is, the distance between the left and right sides of the entire roll infusion device is large), which is not conducive to the subsequent reliable loading into the packaging bag.

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

[0059] The specific embodiments described below are only preferred implementations of the present application, and the protection scope of the present application is not limited thereto. For those skilled in the art, some changes or variations can be made based on or according to the principles, concepts, and spirits of the present application, and the technical solutions formed by these changes or variations should be included in the protection scope of the present application.

[0060] For the automatic wrapping packaging equipment for infusion sets, the air tube posture adjustment device can adjust the posture of the air tube of an infusion set to be processed. Figure 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, the left clamping jaw 7 and the right clamping jaw 8 are located in the vertical direction, and 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; Figure 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. Figure 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 an open state, and the left limit plate 9 and the right limit plate 10 are also in an 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 portion for the hose. Those skilled in the art can understand that the clamping portion of this specific structure is only a specific structural selection; it can be seen from the figure that the finger cylinder 6 is of 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 selection, and 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 air tube 13-5. When the left clamp 7 and the right clamp 8 are closed, the hose 13-1 of the infusion set is clamped, for example, the portion of the hose 13-1 close to the air tube 13-5 can be clamped. Figure 8 Middle Figure (b) and Fig. 9As shown, when the left clamp 7 and the right clamp 8 are closed, the arc groove 7-1 on the left side and the arc groove 8-1 on the right side clamp the part of the hose 13-1 close to the trachea 13-5, and at the same time, the left limit plate 9 presses down the trachea 13-5 to bend the trachea 13-5 downward. Under the action of the left limit plate 9, the trachea 13-5 is arranged downward as a whole, avoiding the trachea 13-5 being on a substantially horizontal plane or tilted upward. As shown in the figure, the rear end of the left limit plate 9 is connected to the left clamp 7, and the shape of the left limit plate 9 is an overall arc, and the height H of the edge of the left limit plate 9 gradually increases from the rear end to the front end of the left limit plate 9 (as shown in FIG. 1 ). Fig.25 As shown in the figure, this shape is a preferred shape, but the specific shape of the left limit plate 9 is not limited thereto, and may also be other shapes that can press the air pipe 13-5 downward. When the left clamp 7 and the right clamp 8 are closed to clamp the hose, there is a situation where the right limit plate 10 presses down the air pipe so that the air pipe is arranged downward as a whole. In other words, whether the right limit plate 10 or the left limit plate 9 works depends on the placement of the air pipe before the left limit plate 9 or the right limit plate 10 acts on the air pipe.

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

[0063] Regarding other specific shapes of the left limit plate and the right limit plate, for example: Figure 26-29 As shown, the left limiting plate 16 is planar in shape as a whole, and the right limiting plate 17 has the same shape as the left limiting plate 16 . Figure 26-29 The finger cylinder is in the open state, and the two limit plates are in the open state. Fig.30 , 31 As shown, the finger cylinder is in a closed state and the two limit plates are in a closed state. Fig.32 , from the rear end to the front end of the left limit plate 16, the height h of the edge 16-1 of the left limit plate 16 gradually increases. When the left limit plate 16 is working, the edge 16-1 presses down the air pipe 13-5. Similarly, the height of the edge of the right limit plate 17 gradually increases.

[0064] like Fig.33 and 34 As shown, two planar left limit plates 16 and right limit plates 17 are symmetrically arranged, and the two sides of the two limit plates gradually become higher in the direction of the symmetry line (refer to Fig.34 direction indicated by the arrow).

[0065] It should be noted that, for the left limiting plate 9 and the right limiting plate 10, both sides of the two limiting plates gradually become higher in the direction of the symmetry line.

[0066] Before the trachea 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 (for example, a 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, and 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 start 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 Figure (b) and Fig. 9 As shown, the posture adjustment of the trachea 13-5 is now completed.

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

[0068] like Fig.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, 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 set to the top of the winding device, the entire material taking device moves downward, the trachea posture adjustment device also moves downward, and the hose of the infusion set 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 Fig.12As shown), the hose clamping mechanism 14-4 then operates 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 works 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 circles, and finally forming a roll, as shown in FIG. Fig.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 may be: the two sets of clamps of the transfer device clamp the front part and the rear part of the rolled infusion set respectively. Fig.12 The rolled infusion set can be divided into an upper part, a lower part, a left part, and a right part, wherein the upper part is the front part and the lower part is the rear part. Then, the two sets of jaws of the transfer device move upward, thereby lifting the rolled infusion set upward, that is, the rolled infusion set is separated from the winding device, and the air tube of the infusion set is in a naturally drooping state.

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

[0072] like Figure 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, and the left guide plate 15-5 is fixedly connected to the hollow gathering block 15-4. The left side of the hollow gathering block 15-4 is connected, the right guide plate 15-6 is connected to the right side of the hollow gathering 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 gathering block 15-4 is provided with a central through hole 15-4-1 whose inner diameter gradually decreases from front to back, and the top of the hollow gathering 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 gathering block 15-4, and along 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 Fig.21The 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 numerical range of the angle α is: 20°<α<60°, and the further preferred numerical range is: 25°<α<40°; for the rear end of the tracheal guide rod 15-7 extending into the central 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 central through hole 15-4-1, and this position structure is only a better choice. The right guide plate 15-6 is provided with an arc-shaped guide concave surface 15-6-1. It should be noted that the provision of the left guide plate 15-5 and the right guide plate 15-6 is a better technical means. The inner side surface of the left guide plate 15-5 can guide the rolled infusion pump to the central 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 rolled infusion pump to the central through hole 15-4-1. The left guide plate 15-5 and the right guide plate 15-6 are used together to form a trumpet-shaped structure; those skilled in the art can understand that the left guide plate 15-5 and the right guide plate 15-6 may not be provided.

[0073] It should be noted that the rear end of the trachea guide rod 15-7 extends into the central through hole 15-4-1 of the hollow gathering block 15-4, refer to Fig. 22 , it can also be set as: the rear end of the trachea guide rod 15-7 is close to the right inner wall of the central through hole 15-4-1.

[0074] refer to Fig.13 The transfer device moves the roll-shaped infusion set to the gathering device 15 in the horizontal plane. Since the air tube of the roll-shaped infusion set is in a naturally drooping state, the air tube will contact the air tube guide rod 15-7 and slide along the air tube guide rod 15-7. Fig.23As shown, as the roll-like infusion set moves toward the central through hole 15-4-1 of the hollow gathering block 15-4, the trachea gradually approaches the body of the roll-like infusion set, and finally the trachea approaches the body of the roll-like infusion set in a posture that is basically in a horizontal plane, and the trachea smoothly enters the central through hole 15-4-1, and then the entire roll-like infusion set is gathered in the central through hole 15-4-1, and the width of the entire roll-like infusion set becomes smaller (that is, the distance between the left and right sides of the entire roll-like infusion set becomes smaller); during the process of the entire roll-like infusion set being gathered in the central through hole 15-4-1, the two sets of jaws of the transfer device will pass through the aisle 15-4-2. The trachea guide rod 15-7 can also adjust the position of the trachea of ​​the roll-like infusion set, so that the position of the trachea of ​​the entire roll-like infusion set output from the central through hole 15-4-1 is basically fixed, which is conducive to the subsequent more convenient and smooth entry of the entire roll-like infusion set into packaging. Finally, the entire roll infusion device output from the central through hole 15-4-1 enters the bagging station, and the entire roll infusion device can be smoothly and reliably loaded into the packaging bag. Fig.24 As shown, Fig.24 The direction of the middle arrow is the translational direction of the entire roll-shaped infusion set. It can be seen that the air tube 13-5 is distributed backwards, so the entire roll-shaped infusion set can enter the packaging bag more conveniently and smoothly. In addition, the air tubes of each roll-shaped infusion set formed by continuous batch operation are distributed backwards, that is, the air tube distribution position of each roll-shaped infusion set is consistent, so that the air tube distribution position of the final roll-shaped infusion set is consistent after being loaded into the packaging bag.

[0075] In some cases, the width of the rolled infusion pump waiting to be gathered is relatively large, so before entering the central through hole 15-4-1 of the hollow gathering block 15-4, the left side of the rolled infusion pump first contacts the left guide plate 15-5 and is thereby guided toward the front entrance of the central through hole 15-4-1, or the right side of the rolled infusion pump first contacts the arc-shaped guide concave surface 15-6-1 of the right guide plate 15-6 and is thereby guided toward the front entrance of the central 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 tracheal guide rod 15-7, the entire rolled infusion set can be transferred reliably and smoothly, thereby improving the transfer effect; this is also beneficial to the gathering operation of the entire rolled infusion set in the hollow gathering block 15-4.
