Description

Technical Field

[0001] The present invention relates to an improved invention of an infusion set packaging device, in particular to an automatic feeding mechanism of an infusion set. Background Art

[0002] The disposable infusion set is used to deliver liquid medicine to the human body, and is mainly composed of an infusion hose, a syringe, a bottle stopper puncture device and a flow rate regulator. Existing disposable infusion sets are packaged in a film bag after being wound, and one packaging bag contains one infusion set. When winding, only one infusion set can be clamped, so the infusion sets should be arranged neatly and adjacent infusion sets should be separated to facilitate winding and clamping.

[0003] At present, the infusion sets are mainly arranged manually. Among them, the invention with publication number CN208086211U and invention name "An automatic tube wrapping bagging machine for infusion sets" adopts manual hanging of infusion sets, that is, manually taking out the infusion sets from the spare hanging area, fixing the upper bottle needle part of the infusion set at the upper fixing buckle in the first rotary conveying mechanism, and the lower part of the infusion set is vertically and freely suspended. Among them, the invention patent with publication number CN109809169B and invention name "An infusion set loading device" combines manual placement of infusion sets with mechanical straightening of infusion sets. Specifically, the operator places the infusion sets one by one on the carrier, so that one side of the puncture needle of the infusion set is just stuck on the head carrier, and the other side of the infusion set is placed on the tail carrier. The loading methods of the infusion sets in the above two patents are different, one is hanging and the other is lying flat, but the infusion sets are still mainly arranged manually, so that the infusion sets are separated and placed in the set position. Therefore, the existing infusion set loading mechanism has problems such as low efficiency and complicated operation. Summary of the invention

[0004] In view of the technical problems existing in the background technology, the technical problem solved by the present invention is to provide an automatic feeding mechanism for an infusion set, so as to realize automatic material sorting and automatic feeding of the infusion set.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solution: the automatic feeding mechanism of the infusion set is characterized by comprising a material sorting device, a conveying device and a material receiving device.

[0006] The material sorting device has a material discharging station at its front end, and comprises a material supporting plate and a material sorting plate arranged longitudinally.

[0007] The material sorting plate is arranged on both sides of the supporting plate.

[0008] The material support plate is lifted up and down and moves forward and backward relative to the material sorting plate, and the material support plate delivers the infusion device on the material sorting plate to the material discharging station;

[0009] The material receiving device comprises a material receiving piece for receiving the infusion set;

[0010] The conveying device conveys the infusion device at the discharging station to the receiving piece at the receiving station.

[0011] Preferably, at least two groups of limit groups are provided on the support plate, each group of limit groups is provided with at least two limit grooves, and the spacing between adjacent limit grooves of the group of limit groups close to the material storage area is smaller than the spacing between adjacent limit grooves of the group of limit groups close to the material discharge station;

[0012] At least one guide group is provided on the material sorting plate, and one guide group is provided with at least two guide grooves, the guide grooves are arranged up and down, and the entrances thereof are at the top, the entrances of the guide grooves correspond to the upper group of adjacent limiting grooves with smaller spacing, and the bottoms of the guide grooves correspond to the lower group of adjacent limiting grooves with larger spacing;

[0013] When sorting materials, the entrance of the guide groove receives the infusion hose sent in by a set of limit groups on the support plate, and the guide groove increases the distance between adjacent conveyors. Then, a set of limit groups under the support plate lifts the infusion hose in the guide groove upward to make it out of the guide groove. The support plate and the sorting plate cooperate to separate the closely arranged infusion devices in an orderly manner, and increase the distance between the infusion devices at the discharge station, which is convenient for subsequent grabbing of the infusion devices.

[0014] Preferably, the material support plate comprises a material storage section and a grading and sorting section, and the material sorting plate is arranged on both sides of the grading and sorting section;

[0015] The two sides of the material storage section are provided with material blocking pieces. When the material storage section moves upward, its upper surface is higher than the upper surface of the material blocking piece, and when the material storage section moves downward, its upper surface is lower than the upper surface of the material blocking piece. A number of infusion sets are laid flat on the material storage section. When the material support plate moves in a U-shape once, the infusion sets in the material storage section move forward one position; and the infusion sets in the grading material sorting section move forward one level.

[0016] An output section is provided between the material storage section and the grading and sorting section, and the output section moves forward and backward relative to the material storage section;

[0017] When the output section receives the material, it is close to the material storage section and the two are connected. When the output section delivers the material, it is far away from the material storage section and corresponds to the entrance of the first group of guide groups on the material sorting plate. Separating the material storage section and the grading material sorting section is conducive to the sorting and separation of the infusion sets.

[0018] Preferably, the section of the material sorting plate where the guide groove is provided is serrated, so that the entrance of the guide groove is enlarged, which is more convenient for receiving the infusion hose.

[0019] The entrances of the same group of guide grooves gather toward the center of this group of guide groups; while maximizing the entrance of the guide groove, the entrance of the guide groove keeps cooperating with the limit group with a smaller spacing, and the bottom of the guide groove cooperates with the limit group with a larger spacing.

[0020] The bottom of the guide groove is arc-shaped and matches the infusion hose; the position of the infusion set in the guide groove is accurately determined so that it corresponds to the limit groove on the support plate, which is conducive to the support plate to stably take out the infusion set in the guide groove.

[0021] The limiting groove of the grading and sorting section is a depth limiting groove, and the vertical section of the depth limiting groove is U-shaped;

[0022] The limiting grooves of the output section are shallow limiting grooves and are arranged continuously in the longitudinal direction, and the depth of the shallow limiting grooves is not greater than the radius of the infusion hose;

[0023] The material storage section is provided with shallow limiting grooves which are arranged continuously in the longitudinal direction, so that the staff can lay the infusion sets flat on the material support plate. Meanwhile, the shallow limiting grooves make the infusion sets on the material support plate arranged in an orderly and uniform manner, so as to prepare for the orderly separation of the subsequent infusion sets.

[0024] The side surface of the material blocking member is an arc surface;

[0025] The material blocking member extends forward and is arranged on both sides of the material sorting plate; the infusion set is placed transversely on the material supporting plate, and the arc surface increases the transverse width to prevent the two ends of the infusion set from being entangled.

[0026] Beating rods are arranged on both sides of the material blocking member, and the beating rods move left and right relative to the material blocking member. The beating rods beat the two ends of the infusion set to prevent the adjacent infusion sets from being entangled.

[0027] Preferably, the discharging station is provided with a discharging plate and a traction component.

[0028] The discharge plate is arranged on both sides of the support plate, and a material trough is provided on the discharge plate to receive the infusion hose fed by the support plate, and the material trough is equipped with a locking groove member;

[0029] The traction component is arranged on the side of the discharge plate and close to the material receiving device, and the traction component includes a traction member for driving the infusion hose to move downward.

[0030] The traction member and the infusion hose are movably arranged, and the traction member is raised and lowered between the material taking station and the in-place station, and the distance between the in-place station and the material trough is close to the length of the infusion hose. The material support plate sends the infusion device to the material discharging station, and the traction member drives the infusion device at the material discharging station to move down, and the infusion hose moves in the material trough until the traction member moves down to the in-place station, at which time one end of the infusion device is blocked by the material trough and the locking slot member, and the position of the infusion device at the material discharging station is unified, which is convenient for subsequent processing.

[0031] Preferably, the discharge plate and the material sorting plate are designed as one piece;

[0032] The number of the material trough, the set of limit grooves and the set of guide grooves on the discharge plate is the same;

[0033] The locking slot parts cooperate with the entrance of the material trough, and a plurality of locking slot parts are installed on a moving plate, and the moving plate moves forward and backward relative to the discharge plate; the locking slot parts are moved by the moving plate to uniformly close or open the material trough.

[0034] The traction member includes a plug plate that moves left and right, and a slot for the infusion hose to enter is provided on the plug plate, and the width of the slot is smaller than the size of the end of the infusion set. When the plug plate is extended, the infusion hose enters the slot, and when the plug plate moves downward, it pushes the end of the infusion set to move the infusion hose downward.

[0035] Preferably, the conveying device includes a material taking part and a delivery part.

[0036] The material taking piece is connected with a rotating shaft, and the rotating shaft drives the material taking piece to flip between the material discharging station and the transfer station. At the material discharging station, the material taking piece clamps the infusion set up and down, and at the transfer station, the material taking piece clamps the infusion set horizontally.

[0037] The delivery member moves longitudinally and transversely relative to the receiving member;

[0038] The material taking part clamps one end of the infusion set at the material taking station and sends it to the transfer station. The delivery part clamps the infusion set delivered by the material taking part at the transfer station and sends it to the material passing channel of the material receiving part. The material receiving part receives the infusion set delivered by the delivery part. The material taking part cooperates with the delivery part to deliver the infusion set to the material receiving part, so that the infusion set is suspended in the material passing channel of the material receiving part, thereby realizing automatic loading and delivery of the infusion set.

[0039] As a preference,

[0040] The material receiving piece is located at the side of the material discharging station, the infusion device is arranged longitudinally at the material discharging station, and the delivery piece rotates horizontally; the material discharging station and the material receiving piece are arranged transversely, so as to reduce the occupied space of the equipment.

[0041] The material taking height of the delivery component matches the material receiving height of the material receiving component; the material delivery component only needs to move horizontally without lifting to deliver the infusion set to the material passing channel of the material receiving component, thereby reducing equipment costs and improving delivery efficiency.

[0042] The material taking piece includes a first clamping plate and a second clamping plate for clamping cooperation, and a plurality of clamping openings are arranged on the first clamping plate and the second clamping plate. When the material taking piece is in a horizontal clamping state, the second clamping plate is close to the material discharging station relative to the first clamping plate, and the second clamping plate moves horizontally and vertically relative to the first clamping plate.

[0043] After the material is taken, the material picking part flips toward the material receiving part, and the material picking part moves horizontally toward the material receiving part to the material receiving station in a horizontal clamping state. The material picking part can clamp multiple infusion sets at one time to improve the efficiency of transportation, and after the material picking part and the delivery part complete the handover, the second clamping plate moves relative to the first clamping plate to avoid the infusion set, so as to avoid collision with the infusion set when the material picking part is reset.

[0044] Preferably, the material receiving device also includes a feeding piece, which moves laterally relative to the material receiving piece and horizontally delivers the infusion sets received by the material receiving piece to the discharge end of the material receiving piece one by one; when the infusion set at the discharge end of the material receiving piece is taken away, the feeding piece moves the infusion set in the material transfer channel to the discharge end by one position, so that the discharge end remains filled with material, and in this way, the feeding stroke is short and the stability is high.

[0045] The material receiving pieces are provided in a plurality of groups, and the plurality of groups of material receiving pieces are evenly arranged in the longitudinal direction;

[0046] The material taking part and the delivery part clamp at least two infusion sets at a time and the number of clamps is the same;

[0047] The delivery parts are provided with two groups, and the two groups of delivery parts work alternately. The delivery parts deliver multiple infusion sets at one time and dock with multiple receiving parts, which not only ensures work efficiency but also reduces equipment cost.

[0048] Preferably, the number of groups of the material feeding parts and the material receiving parts is the same;

[0049] The delivery member is a first clamping member, and the first clamping member includes a third clamping plate and a fourth clamping plate for clamping cooperation;

[0050] The feeding member is a second clamping member, and the second clamping member includes a second movable seat and a fifth clamping plate and a sixth clamping plate for clamping cooperation;

[0051] The second movable seat is arranged between adjacent material receiving parts, and the fifth clamping plate and the sixth clamping plate of the adjacent material feeding parts are arranged on the second movable seat, and the fifth clamping plate and the sixth clamping plate move longitudinally on the second movable seat; the space of the material receiving station is limited, and the material feeding parts reasonably utilize the space of the material receiving station, and the structural design is reasonable and compact.

[0066] The following describes the details and working principles of the implementation mode and embodiments of the present invention in conjunction with the accompanying drawings. Figure 3 , the X-axis is the horizontal direction, that is, the left-right direction; the Y-axis is the longitudinal direction, that is, the front-back direction; and the Z-axis is the vertical direction, that is, the up-down direction.

[0067] The automatic feeding mechanism of the infusion device includes a material sorting device, a conveying device 8 and a material receiving device 9. The front end of the material sorting device is a material discharging station, and the material sorting device includes a material supporting plate 3 and a material sorting plate 2. The material sorting plates are arranged on both sides of the material supporting plate. The material supporting plate 3 is lifted up and down and moves forward and backward relative to the material sorting plate 2. The material supporting plate delivers the infusion device on the material sorting plate to the material discharging station.

[0068] The support plate 3 is provided with at least two limit groups, each of which is provided with at least two limit grooves 34. Figure 6 , six limit grooves form a group, the infusion device 1 is transported from the storage area 100 to the discharge station 200, the transport direction is forward, the spacing between adjacent limit grooves of the limit group near the storage area is smaller than the spacing between adjacent limit grooves of the limit group near the discharge station. The material sorting plate 2 is arranged on both sides of the material support plate 3, and at least one group of guide groups is provided on the material sorting plate 2, and one group of guide groups is provided with at least two guide grooves 21, the guide grooves are arranged up and down, and their entrances are on the top, the entrance 211 of the guide groove corresponds to the limit grooves of the previous group with smaller adjacent spacing, and the bottom 212 of the guide groove corresponds to the limit grooves of the next group with larger adjacent spacing. When sorting materials, the support plate moves up and forward so that the upper limit group on the support plate moves to the top of the entrance 211 of the guide groove, and then the support plate 3 moves down. The entrance 211 of the guide groove receives the infusion hose 13 sent by the limit group with a smaller spacing between adjacent limit grooves on the support plate. The infusion device is guided into the bottom 212 of the guide groove through the guide groove. The guide groove 21 increases the spacing between adjacent conveyors. The support plate 3 retreats, and the infusion device entering the bottom of the guide groove corresponds to the limit group with a larger spacing between the next group of adjacent limit grooves. The support plate 3 moves up again, and the next limit group of the support plate lifts up the infusion hose 13 in the guide groove 21 to make it detach from the guide groove 21. The support plate 3 moves forward again, and the limit group on the support plate sends the second group of infusion tubes with a smaller spacing to the top of the guide groove 21, while the limit group on the support plate sends the infusion tubes with a larger spacing forward. By setting more limit groups on the support plate 3 and more guide groups on the material sorting plate 2, the distance between adjacent infusion pumps 1 can be gradually increased during the forward conveyance process, and finally the required output distance is reached, and the last limit group of the support plate sends the infusion tube to the discharge station.

[0069] See attached Figure 5The section of the guide groove 21 provided on the material sorting plate 2 is serrated, that is, the partitions between adjacent guide grooves are serrated, reducing the space occupied by the partitions between adjacent guide grooves, so that the entrance 211 of the guide groove is as large as possible, which is more conducive to receiving the infusion hose 13. The entrances of the same group of guide grooves are gathered toward the center direction of this group of guide groups, and the partitions are inclined toward the center direction. Under the condition of maximizing the entrance of the guide groove, the entrance 211 of the guide groove is kept matching with the limiting group with a smaller spacing, so as to receive the infusion hose, and the bottom 212 of the guide groove is matched with the limiting group with a larger spacing, so that the infusion set 1 in the guide groove 21 enters the limiting groove of this group. The bottom 212 of the guide groove is arc-shaped and matches the infusion hose 13. The longitudinal position of the infusion set is accurately determined by the bottom 212 of the guide groove, so that the infusion hose corresponds to the limiting groove 34 on the material support plate, which is conducive to the material support plate 3 to stably take out the infusion set in the guide groove. The vertical section of the limiting groove 34 is U-shaped, and the infusion hose goes deep into the limiting groove 34, so that it can be kept in the limiting groove when it leaves the guide groove.

[0070] The material support plate 3 includes a material storage section 31 and a graded material handling section 32. The infusion sets are densely distributed in the material storage section 31. The infusion sets are gradually separated in the graded material handling section 32, and the spacing between adjacent infusion sets gradually increases. The material handling plate 2 is arranged on both sides of the graded material handling section, and material blocking pieces 4 are arranged on both sides of the material storage section. After the material storage section moves up, its upper surface is higher than the upper surface of the material blocking piece, and after the material storage section moves down, its upper surface is lower than the upper surface of the material blocking piece. The material storage section 31 cooperates with the material blocking pieces 4 on both sides, and the material support plate 3 moves up to lift up the infusion set 1, and the infusion set is higher than the material blocking piece 4. The material support plate moves forward with the infusion set, and after moving forward, the material support plate moves down and is lower than the material blocking piece 4, and the infusion set is placed on the material blocking piece. That is to say, the material support plate 3 moves in a U-shaped motion once, and the infusion set 1 of the material storage section 31 moves forward by one position. The grading material sorting section cooperates with the material sorting plates 2 on both sides, and the supporting plate 3 moves in a U-shape once, and the infusion device of the grading material sorting section 32 moves forward one level.

[0071] See attached Figure 4The side of the material stopper 4 is an arc surface, and the material stoppers on both sides are roughly cylindrical. The infusion set is placed horizontally on the support plate 3, and the two ends of the infusion set are drooping. The arc surfaces of the material stoppers on both sides can increase the horizontal width, increase the distance between the two ends of the infusion set, and avoid the two ends of the infusion set from being entangled; and the arc formed by the natural droop of the infusion set 1 from the support plate is relatively consistent with the arc surface of the material stopper, so that the infusion set 1 and the material stopper 4 have a large contact area, so that during the transfer process, the shaking of the infusion set can be reduced, and the transportation is more stable and accurate. The material stopper 4 can also extend forward and be arranged on both sides of the material sorting plate 2, and play the same role on the graded material sorting section 32. The infusion set is long, and the drooping parts of adjacent infusion sets may also be entangled. To solve this problem, a beating rod 5 is provided on both sides of the material stopper 4, and the beating rod 5 moves left and right relative to the material stopper 4. The beating rod reciprocates to push the drooping part of the infusion set 1, so that the entangled infusion set is dispersed.

[0072] The material storage section can directly deliver the infusion pump 1 at its tail end directly to the first group of guide grooves of the material sorting plate 2. Since the infusion pumps in the material storage section 31 are densely distributed, the group of infusion pumps that are about to enter the guide groove 21 will be affected by the next group of infusion pumps. In order to improve the stability of graded transportation, an output section 33 is provided between the material storage section 31 and the graded material sorting section 32, and the output section moves forward and backward relative to the material storage section 31. When the output section receives materials, it is close to the material storage section 31 and the two are connected, so that the infusion pump at the tail end of the material storage section 31 enters the output section; when the output section feeds materials, it is away from the material storage section 31 and corresponds to the entrance of the first group of guide groups on the material sorting plate 2, and the infusion pump entering the first group of guide grooves is separated from the next group of infusion pumps through the output section, so that the first group of guide grooves on the material sorting plate 2 only receives the infusion pump 1 of the output section and will not be disturbed by the next group of infusion pumps, thereby improving stability; and the output section 33 moves forward a distance to provide space for material sorting, and at the same time, the forward and backward moving stroke of the material storage section is independent of the forward and backward moving stroke of the grading material sorting section in front.

[0073] The limiting groove 34 of the grading material sorting section is a depth limiting groove, and the vertical section of the depth limiting groove is U-shaped. The depth of the depth limiting groove is deep, so that the infusion set can be kept in the limiting groove 34 when it is separated from the guide groove 21. The storage section 31 is provided with shallow limiting grooves and arranged continuously in the longitudinal direction. The depth of the shallow limiting grooves is not greater than the radius of the infusion hose 13, so that it is convenient for the staff to lay the infusion set flat on the support plate 3. At the same time, the shallow limiting grooves make the infusion sets on the support plate orderly and uniformly arranged, preparing for the orderly separation of the subsequent infusion sets. In order to better connect the output section 33 with the storage section 31, the limiting grooves 34 of the output section also adopt shallow limiting grooves and are arranged continuously in the longitudinal direction.

[0074] The material storage section 31 is connected to a first power member that drives it to move forward and backward on the first lifting plate. A power member 35 that drives the output section 33 to move forward and backward is installed on the material storage section 31. The material storage section 31 is connected to a second power member that drives it to move forward and backward on the second lifting plate. The forward and backward movement of the material storage section 31 and the grading material handling section 32 on the frame is driven by different power members, so that the forward and backward movement strokes of the material storage section 31 and the grading material handling section 32 are different, which is more convenient for operation and control. The lifting of the first lifting plate and the second lifting plate can be driven by one power drive or two power drives. In addition, the grading material handling section can also be divided into two or three blocks according to the number of guide groups of the material handling plate 2. For example, there are three guide groups of the material handling plate 2, the length of the first guide group is the shortest, and the length of the third guide group is the longest. The material support plate of the grading material handling section 32 can be divided into three blocks, and the forward and backward movement of each support plate is independently equipped with power, so that the spacing between adjacent guide groups can be shortened, and the conveying stroke of the support plate 3 can be shortened. If one power is used, the structure is simple and the cost is low, but the minimum stroke of the supporting plate 3 moving forward and backward is the length of the third guide group, and a corresponding distance must be reserved between adjacent guide groups, so that the infusion pump can be sent to the guide groove 21 of the corresponding guide group through a supporting plate 3.

[0075] The material discharging station 200 is provided with a material discharging plate 7 and a traction component 6. The material discharging plate 7 is arranged on both sides of the material supporting plate 3. The material discharging plate 7 is provided with a material trough 71. The material trough 71 receives the infusion hose 13 sent by the material supporting plate, and the material trough 71 is equipped with a locking groove. The traction component 6 includes a traction member that drives 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-position station. The distance between the in-position station and the material trough 71 is close to the length of the infusion hose 13.

[0076] See attached Figure 2The 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. The flow rate regulators 12 and bottle stopper piercers 14 at both ends of the infusion hose are relatively large in size. The shell surface of the syringe 11 is provided with a flange 15, and the outer diameter of the flange is larger than the syringe shell. The infusion hose is placed on the support plate 3, and the infusion set is oriented in the same direction on the support plate, and the flow rate regulators 12 and bottle stopper piercers 14 at both ends droop naturally. The supporting plate delivers the infusion pump to the material trough 71 of the discharging station 200, and the locking groove part closes the material trough. Assuming that the bottle stopper piercer 14 is on the side of the traction part, the traction part moves downward relative to the infusion hose 13. When the traction part moves downward and hits the bottle stopper piercer 14, it drives the infusion pump 1 to move downward, and the infusion hose 13 moves in the material trough until the traction part moves down to the position in place. At this time, the flow rate regulator 12 at the other end of the infusion pump 1 is blocked by the material trough and the locking groove part to prevent the infusion pump from leaving the material trough 71. At this time, the position of the infusion pump at the discharging station 200 is unified, so that the position of the material taking part of the conveying device to take the infusion pump is consistent. The discharging plate 7 is designed as an integral part with the material sorting plate 2, that is, the material sorting plate 2 extends to the discharging station 200 to form the discharging plate 7, which is easier to install. The number of the material trough, a set of limit grooves, and a set of guide grooves on the discharging plate is the same, see the attached Figure 4-6 , a group of six. The locking groove member 72 cooperates with the entrance of the trough 71, and several locking groove members are installed on the moving plate 73. The moving plate moves forward and backward relative to the discharge plate 7. The multiple locking groove members 72 are moved simultaneously by the moving plate 73, and the trough is closed or opened uniformly. The traction member can be a clamping member, and the clamping opening of the clamping member is larger than the infusion hose but smaller than the end of the infusion device, so that the clamping member and the infusion hose are movably arranged. See attached Figure 7 The traction member includes a plug plate 61 that moves left and right. The plug plate 61 is provided with a slot 62 for the infusion hose 13 to enter. The width of the slot is smaller than the size of the end of the infusion set. The end of the infusion set refers to the flow rate regulator 12 or the bottle plug piercer 14 at both ends of the infusion hose 13, that is, the flow rate regulator or the bottle plug piercer cannot pass through the slot 62. When the infusion set is sent to the discharge station 200, the plug plate extends, the infusion hose enters the slot, and the plug plate moves downward to push the end of the infusion set, so that the infusion hose moves downward. The structure is simple and the use effect is good.

[0077] The conveying device delivers the infusion device at the discharging station to the receiving device at the receiving station. The conveying device 8 includes a material picking device 81 and a delivery device 83. The material picking device and the delivery device can clamp at least two infusion devices 1 at a time, and the number of clamps can be the same. The material picking device 81 is connected to a rotating shaft 82, which drives the material picking device to flip between the discharging station and the transfer station. See the attached Figure 8The rotating shaft is arranged horizontally, and is connected to a power member that drives the rotating shaft to rotate forward or reversely, and the rotating shaft drives the material taking member to flip back and forth between the material discharging station and the transfer station. At the material discharging station 200, the material taking member 81 clamps the infusion set 1 up and down, and at the transfer station 300, the material taking member clamps the infusion set horizontally, see the attached Figure 8 and 9 , the material picking member 81 is at the transfer station 300, horizontally clamping the infusion set, and the clamped infusion set 1 hangs vertically. The delivery member 83 moves longitudinally and transversely relative to the receiving member 91. The infusion set 1 is placed at the discharge station 200, and the rotating shaft 82 drives the material picking member 81 to flip toward the discharge station 200. The material picking member 81 clamps one end of the infusion set 1 at the discharge station 200, and the rotating shaft 82 rotates in the opposite direction, driving the material picking member 81 to flip in the opposite direction to the transfer station 300. The delivery member 83 moves to the transfer station 300 and clamps the infusion set 1 transported by the material picking member. The material picking member releases the infusion set, and the delivery member moves to send the infusion set to the material transfer channel 92 of the receiving member. The receiving member 91 receives the infusion set transported by the delivery member, and the infusion set is suspended on the receiving member 91.

[0078] 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 discharge 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 set and is close to the end of the flow rate regulator 12, and is at a certain distance from the end of the syringe 11. The present invention avoids the collision of the material picking member with the infusion set 1 when picking materials at the discharge station 200 by horizontally and horizontally moving the second clamping plate 812 relative to the first clamping plate 811. After picking materials, the material picking member 81 flips toward the material receiving member, and in a horizontal clamping state, the material picking member moves horizontally to the transfer station. The horizontal movement of the material picking member 81 allows the infusion set 1 after picking materials to give way to the discharge station 200, so as to facilitate the next group of infusion sets 1 to be sent to the discharge station.

[0079] The delivery member 83 is a first clamping member, which 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 moving seat 833, shortening the moving stroke of the third clamping plate and the fourth clamping plate. The receiving member 91 is located on the side of the discharging station 200, see the attached Figure 1The receiving station 400 is on the left side of the discharging station 200, and the infusion pump 1 is arranged vertically at the discharging station, and the discharging station and the receiving piece are arranged horizontally, which reduces the space occupied by the equipment. The delivery piece 83 rotates horizontally to turn the vertically arranged infusion pump 1 horizontally to a horizontal arrangement, and finally enters the material transfer channel 92 of the receiving piece. The material picking height of the delivery piece matches the material receiving height of the receiving piece. The material delivery piece 83 only needs to move horizontally without lifting to deliver the infusion pump 1 to the material transfer channel of the receiving piece, which reduces the movement of the delivery piece, reduces the equipment cost, and improves the delivery efficiency. See attached Figure 4 and 5 The receiving parts are provided with six groups, the material taking parts and the 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 not only ensures work efficiency but also reduces equipment costs.

[0080] The material receiving device includes a material receiving piece 91 for receiving the infusion set, and the material receiving piece is provided with a material passing passage 92 which is transversely passed through, and the material passing passage is larger than the narrower part of the infusion set and smaller than the wider part of the infusion set, and the infusion set 1 is suspended on the material receiving piece 91. The material receiving piece 91 is provided with a plurality of groups, and the plurality of groups of material receiving pieces 91 are evenly arranged longitudinally. Each group of material receiving pieces 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 both provided with material passing passages, namely, an upper material passing passage 921 and a lower material passing passage 922, and 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 transfer channel 921, while the flange 15 on the housing surface is larger than the upper material transfer channel 921, the infusion hose 13 is smaller than the lower material transfer channel 922, and the flow rate regulator 12 is larger than the lower material transfer 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.

[0081] 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. Fig.11 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.

[0082] The power parts such as motors and cylinders used for the movement and rotation of each component of the present invention 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 movement of each component, but the cost is relatively higher.

The infusion pump 1 is laid flat on the material storage section 31 of the material support plate, and the head and tail of the infusion pump 1 are in the same direction, and the material storage section 31 of the material support plate can be continuously fed. The material support plate 3 moves up above the material blocking member 4 and the material sorting plate 2 to lift the infusion pump, and the material storage section 31, the first section of the graded material sorting section, and the second section of the graded material sorting section move forward, and the infusion pump 1 moves accordingly. The infusion pumps in the material storage section 31 all move forward one position, and the limit group of the graded material sorting section 32 sends the infusion pump to the next guide group and above the discharge station 200. The output section 33 moves forward relative to the material storage section 31, so that this group of infusion pumps moves to above the first guide group. Then, the supporting plate 3 moves downward, the infusion device of the material storage section 31 is placed on the material stopper 4, and the infusion devices of the output section 33 and the grading material handling section 32 enter the guide groove 21 of the corresponding guide group and the material groove 71 of the material discharging station 200, and the infusion device enters the bottom of the guide groove 21. The infusion devices of the same group pass through the guide groove 21 so that the distance between adjacent ones becomes larger. The output section 33 moves back and resets relative to the material storage section and fits with the tail end of the material storage section. The material storage section, the first section of the grading material handling section, and the second section of the grading material handling section move backward and reset, thus completing one conveying. When the supporting plate moves upward again, the infusion device at this position is lifted.

Then, the plug plate 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 place, at which time the flow rate regulator 12 at the other end of the infusion set is blocked by the material trough 71 and the locking slot part 72, 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 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.

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.
