DETAILED DESCRIPTION

[0040] The following describes the details and working principle of the implementation and embodiment of the utility model in conjunction with the accompanying drawings. In the drawings, the X axis is the horizontal direction, also the left-right direction; the Y axis is the longitudinal direction, also the front-back direction; and the Z axis is the vertical direction, also the up-down direction.

[0041] The feeding mechanism of the infusion set includes a conveying device 8 and a receiving device 9, wherein the receiving device includes a receiving piece 91 for receiving the infusion set, and the receiving piece is provided with a transversely passing material passage 92, which is larger than the narrower part of the infusion set and smaller than the wider part of the infusion set. The infusion set 1 is suspended on the receiving piece 91. Figure 6 The infusion set 1 is composed of an infusion hose 13, a syringe 11, a bottle stopper piercer 14 and a flow rate regulator 12. The infusion hose 13 is the thinnest, and the flow rate regulators 12 and bottle stopper piercers 14 at both ends of the infusion hose are larger in size. A flange 15 is provided on the shell surface of the syringe 11, and the outer diameter of the flange is larger than the syringe shell. Figure 4In the embodiment, the material receiving parts 91 are provided with several groups, and the several groups of material receiving parts 91 are evenly arranged in the longitudinal direction. Each group of material receiving parts is provided with an upper material receiving plate 911 and a lower material receiving plate 912, and the upper material receiving plate and the lower material receiving plate are provided with material passing channels, namely, an upper material passing channel 921 and a lower material passing channel 922, respectively. The spacing between the upper material receiving plate and the lower material receiving plate matches the spacing between the housing flange 15 and the flow rate regulator 12. The syringe housing is smaller than the upper material passing channel 921, and the flange 15 on the housing surface is larger than the upper material passing channel 921, the infusion hose 13 is smaller than the lower material passing channel 922, and the flow rate regulator 12 is larger than the lower material passing channel 922, so that the infusion set 1 is suspended on the upper material receiving plate 911 and the lower material receiving plate 912, and the upper material receiving plate and the lower material receiving plate play a dual material receiving role.

[0042] The conveying device 8 includes a material picking piece 81 and a delivery piece 83. The material picking piece and the delivery piece clamp at least two infusion pumps 1 at a time, and the number of clamps is the same. The material picking piece 81 is connected to a rotating shaft 82, and the rotating shaft drives the material picking piece to flip between the discharging station and the transfer station. In the figure, the rotating shaft is horizontally arranged and connected to a power member that drives it to rotate. The power member drives the rotating shaft to rotate forward or reverse, and the rotating shaft drives the material picking piece to flip back and forth between the discharging station and the transfer station. At the discharging station 200, the material picking piece 81 clamps the infusion pump 1 up and down, and at the transfer station 300, the material picking piece clamps the infusion pump horizontally. In the attached figure, the material picking piece 81 clamps the infusion pump horizontally at the transfer station 300, and the clamped infusion pump 1 hangs vertically. The delivery piece 83 moves longitudinally and laterally relative to the material receiving piece 91. The infusion pump 1 is placed at the discharge station 200, and the rotating shaft 82 drives the material picking piece 81 to flip toward the discharge station 200. The material picking piece 81 clamps one end of the infusion pump 1 at the discharge station 200, and the rotating shaft 82 rotates in the opposite direction, driving the material picking piece 81 to flip in the opposite direction to the transfer station 300. The delivery piece 83 moves to the transfer station 300 and clamps the infusion pump 1 transported by the material picking piece. The material picking piece releases the infusion pump, and the delivery piece moves to send the infusion pump to the material transfer channel 92 of the material receiving piece. The material receiving piece 91 receives the infusion pump transported by the delivery piece, and the infusion pump is suspended on the material receiving piece 91.

[0043] The material picking member 81 includes a first clamping plate 811 and a second clamping plate 812 for clamping cooperation. The first clamping plate and the second clamping plate are provided with a plurality of clamping openings. When the material picking member is in a horizontal clamping state, the second clamping plate is close to the material discharging station 200 relative to the first clamping plate, and the second clamping plate moves horizontally and horizontally relative to the first clamping plate. The material picking member clamps the syringe of the infusion device and is close to the end of the flow rate regulator 12, and has a certain distance from the end of the syringe 11. The utility model avoids the infusion device 1 of the material discharging station 200 by horizontally and horizontally moving the second clamping plate 812 relative to the first clamping plate 811, and avoids the collision with the infusion device 1 when the material picking member is picking up materials at the material discharging station 200. After picking up materials, the material picking member 81 flips toward the material receiving member, and in the horizontal clamping state, the material picking member moves horizontally toward the material receiving member to the transfer station 300. The horizontal movement of the material taking member 81 allows the infusion sets 1 after taking the material to make way for the discharging station 200, so as to facilitate the next group of infusion sets 1 to be sent to the discharging station.

[0044] The delivery member 83 is a first clamping member, and the first clamping member includes a third clamping plate 831 and a fourth clamping plate 832 for clamping cooperation; the third clamping plate and the fourth clamping plate move relative to each other on the first movable seat 833, shortening the moving stroke of the third clamping plate and the fourth clamping plate. The material receiving member 91 is on the side of the material discharging station 200, and the material receiving station 400 in the figure is on the left side of the material discharging station 200. The infusion set 1 is arranged longitudinally at the material discharging station, and the material discharging station and the material receiving member are arranged transversely, reducing the occupied space of the equipment. The delivery member 83 rotates horizontally to turn the longitudinally arranged infusion set 1 horizontally to a transverse arrangement, and finally enters the material transfer channel 92 of the material receiving member. The material picking height of the delivery member matches the material receiving height of the material receiving member, and the material dispensing member 83 only needs to move horizontally without lifting to deliver the infusion set 1 to the material transfer channel of the material receiving member, reducing the movement of the delivery member, reducing the equipment cost, and improving the delivery efficiency. The receiving parts in the figure are provided with six groups, the material taking parts and delivery parts clamp six infusion sets, and the delivery parts can deliver six infusion sets to the receiving parts at one time. The delivery parts are provided with two groups, and the two groups of delivery parts work alternately. When one group of delivery parts is delivering, the other group of delivery parts waits and receives the next group of infusion sets, which ensures work efficiency and reduces equipment costs.

[0045] The receiving device 9 also includes a feeding member 93, which moves horizontally relative to the receiving member 91, and horizontally delivers the infusion devices received by the receiving member to the discharge end of the receiving member one by one. One end of the material passage 92 is for feeding, and the other end is for discharging, that is, the discharge end of the receiving member. When the infusion device at the discharge end of the receiving member is taken away, the feeding member 93 moves the infusion device in the material passage 92 to the discharge end by one position, so that the discharge end remains filled with material, so that the feeding stroke is short and the stability is high. The number of groups of the feeding member and the receiving member is the same; the feeding member is a second clamping member, and the second clamping member includes a second movable seat 933 and a fifth clamping plate 931 and a sixth clamping plate 932 for clamping. Due to the limited space of the receiving station 400, the second movable seat is arranged between adjacent receiving members 91, and the fifth clamping plate 931 and the sixth clamping plate 932 of the adjacent feeding member 93 are arranged on the second movable seat, and the fifth clamping plate and the sixth clamping plate move longitudinally on the second movable seat 933. Figure 4 That is to say, one receiving member 91 is equipped with one feeding member 93, two clamping plates of one feeding member 93 are arranged on two second movable seats 933, and one movable seat serves two feeding members 93. In this way, the space of the receiving station 400 is reasonably utilized and the feeding demand is met. The feeding member 93 is lifted and lowered relative to the receiving member 91. After the feeding is completed, the feeding member 93 moves down to avoid interference with the work of other components.

[0046] The discharging station 200 is provided with a discharging plate 7 and a traction component 6, wherein at least two discharging plates are provided and are longitudinally parallelly arranged, and a plurality of material grooves 71 are evenly arranged on the discharging plate, and the material grooves are equipped with locking groove parts 72; the infusion hose of the infusion device is placed in the material groove, and the orientation of the infusion device on the supporting plate 3 is consistent, and the flow rate regulators 12 and the bottle stopper piercers 14 at both ends droop naturally, and the material groove is closed by the locking groove part to prevent the infusion hose from detaching from the material groove.

[0047] The traction component 6 includes a traction member for driving the infusion hose 13 to move downward. The traction member and the infusion hose 13 are movably arranged. The traction member is lifted and lowered between the material taking station and the in-place station. The distance between the in-place station and the material trough 71 is close to the length of the infusion hose 13. The bottle plug piercer 14 is on the traction member side. The traction member moves downward relative to the infusion hose 13. When the traction member moves downward and hits the bottle plug piercer 14, it drives the infusion set 1 to move downward, and the infusion hose 13 moves in the material trough until the traction member moves downward to the in-place station. At this time, the flow rate regulator 12 at the other end of the infusion set 1 is blocked by the material trough and the locking slot member to prevent the infusion set from being separated from the material trough 71. At this time, the position of the infusion set at the material discharging station 200 is unified, so that the position of the traction member taking the infusion set is consistent. The number of the material troughs on the discharge plate is the same as the number of the clamping openings of the material taking part. In the figure, there are six material troughs 71. The locking groove part 72 cooperates with the entrance of the material trough. Several locking groove parts are installed on the moving plate 73. The moving plate moves forward and backward relative to the discharge plate 7. The multiple locking groove parts 72 are moved simultaneously by the moving plate 73, and the material trough 71 is closed or opened uniformly. The traction part can be a clamping part. The clamping opening of the clamping part is larger than the infusion hose but smaller than the end of the infusion device. In this way, the clamping part and the infusion hose are movably arranged. In the figure, the traction part includes a plug plate 61 that moves left and right. The plug plate is provided with a slot 62 for the infusion hose to enter. The width of the slot is smaller than the size of the end of the infusion device. The end of the infusion device refers to the flow rate regulator 12 or the bottle stopper piercer 14 at both ends of the infusion hose 13, that is, the flow rate regulator or the bottle stopper piercer cannot pass through the slot 62. When the infusion set is delivered to the discharging station 200, the insert plate 61 extends, the infusion hose 13 enters the slot 62, and the insert plate 61 moves downward to push the end of the infusion set, so that the infusion hose 13 moves downward. The structure is simple and the use effect is good.

[0048] The power parts such as motors and cylinders used for the movement and rotation of the components of the utility model can be driven independently or linked through a transmission structure. Usually, an independent power part driving structure is adopted, which is more streamlined and easier to control the movements of the components, but the cost is relatively higher.

[0049] The working principle of the preferred embodiment is further described below in conjunction with the accompanying drawings: at the discharge station, the infusion set is sent to the material trough 71 of the discharge station 200, the movable plate 73 moves, the locking slot part 72 closes the material trough 71, the plug plate 61 extends, and the infusion hose 13 enters the slot 62. Then, the plug plate 61 moves downward, and when the plug plate moves downward and hits the bottle plug piercer 14, the infusion set 1 is pulled downward, and the infusion hose 13 moves in the material trough 71 until the plug plate moves downward to the position in which it is in place. At this time, the flow rate regulator 12 at the other end of the infusion set is blocked by the material trough and the locking slot part, and the position of the infusion set at the discharge station is unified. At this time, the infusion set of the transfer station 300 has been taken away by the delivery component, the second clamping plate of the material picking component is away from the first clamping plate, the material picking component moves horizontally toward the discharge station, and the rotation of the shaft drives the material picking component to rotate toward the discharge station, the material picking component is at the discharge station, the second clamping plate is below the first clamping plate, the second clamping plate moves horizontally toward the first clamping plate, and the second clamping plate moves upward, the first clamping plate and the second clamping plate clamp the syringe up and down. The moving plate 73 moves in the opposite direction, the trough 71 opens, the shaft rotates in the opposite direction, the material picking component rotates to the transfer station 300, and the trough of the discharge station receives the next group of infusion sets. The third and fourth clamping plates of the delivery component are opened, and the delivery component moves horizontally to the transfer station. The delivery component is above the material-picking component, and the third and fourth clamping plates are closed to clamp the infusion pump at the transfer station, and the clamping position is below the flange of the shell. Then the material-picking component releases the infusion pump, and the delivery component rotates horizontally to change the longitudinally arranged infusion pumps into a transverse arrangement. The delivery component moves horizontally to deliver a group of infusion pumps to the corresponding material receiving component's material transfer channel, and then the delivery component releases the infusion pump, and the flange of the shell is placed on the upper material receiving plate. The delivery component exits the material receiving station, rotates horizontally toward the transfer station, and waits for the next delivery. At the material receiving station, each time an infusion pump is output, the feeding component clamps the infusion pump at the material receiving station and moves one position toward the discharge end. When a group of infusion pumps of the material receiving component is about to run out, the delivery component replenishes them in time.
