DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0043] Example 1

[0044] Reference Figure 1-Figure 9 , which is the first embodiment of the present invention, is an infusion bag sorting device with a deviation correction function, comprising:

[0045] A workbench for carrying objects;

[0046] The deviation correction unit 100 is provided with a deviation correction component 102 for correcting the direction of the infusion bag and a driving component 101 for driving the deviation correction component 102 to correct the direction of the infusion bag;

[0047] The transport screening unit 200 is provided with a screening component 206 for screening and transporting infusion bags with different orientations according to the deviation correction result of the deviation correction unit 100 on the orientation of the infusion bags;

[0048] The deviation correction unit 100 and the transport screening unit 200 are both fixedly arranged on a workbench.

[0049] The driving assembly 101 includes a support frame 1015 fixedly mounted on a workbench, a transmission shaft 1 is rotatably mounted on the support frame 1015, a cam 1011 is fixedly mounted on one end of the transmission shaft 1, and a motor 1013 is also mounted on the support frame 1015, and a driving shaft of the motor 1013 is in driving connection with the other end of the transmission shaft 1;

[0050] The workbench is also provided with a correction component 102, on which a transmission shaft 2 is rotatably provided. Bat-shaped pendulum block 1 1021 and bat-shaped pendulum block 2 1022 are fixed at both ends of the transmission shaft 2, and a reciprocating part which swings back and forth as the cam 1011 rotates is provided on the bat-shaped pendulum block 2 1022.

[0051] The reciprocating member includes a connecting rod 1012 hingedly provided on the cam 1011, and the other end of the connecting rod 1012 is hingedly provided with a fixing block 1016;

[0052] A mounting block 1014 is fixedly provided on one side of the bat-shaped pendulum block 1021 . A through slot is provided on the mounting block 1014 , and the fixing block 1016 is fixedly installed in the through slot of the mounting block 1014 .

[0053] Among them, the driving shaft of the motor 1013 is connected with the transmission shaft 1 through transmission. When the motor is started, the driving shaft drives the transmission shaft 1 to rotate. A cam 1011 is fixed at one end of the transmission shaft 1. As the transmission shaft 1 rotates, the axis of the hinged end of the cam 1011 performs periodic lifting and lowering motion. One end of the connecting rod 1012 is hinged on the cam 1011, and the other end is hinged on the fixed block 1016, and the fixed block 1016 is installed in the through groove of the mounting block 1014. Therefore, when the axis of the hinged end of the cam 1011 rises and falls, the connecting rod 1012 drives the fixed block 1016 to move back and forth in the through groove of the mounting block 1014, but the fixed block 1016 is fixedly connected in the through groove of the mounting block 1014, so when the axis of the hinged end of the cam 1011 rises and falls, the mounting block 1014 will perform periodic swinging; the bat-shaped pendulum block 1021 and the bat-shaped pendulum block 2 1022 are respectively fixed at the two ends of the transmission shaft 2. Since the transmission shaft 2 is rigidly connected to the bat-shaped pendulum block, when the fixed block 1016 swings back and forth, the transmission shaft 2 is driven to rotate, thereby causing the flexible cloth 1024 on the bat-shaped pendulum block 1022 to swing back and forth.

[0054] The deviation correction component 102 includes two mounting rods 1023 fixedly mounted on the second bat-shaped pendulum block 1022. The two mounting rods 1023 are symmetrically mounted on the second bat-shaped pendulum block 1022. Flexible cloths 1024 are fixedly mounted on the two mounting rods 1023.

[0055] The deviation correction component 102 includes a second support frame 1027, on which two groups of four limiting columns 1025 are obliquely arranged, and the connection between the four limiting columns 1025 and the second support frame 1027 is rectangularly distributed, and the other ends of the four limiting columns 1025 are provided with a limiter 1026, and the limiter 1026 is provided with a limiting groove with a width slightly larger than the width of the infusion bag, and the height of the limiter 1026 is lower than the height of the second support frame 1027;

[0056] A small gap is left between the two groups of the limiting posts 1025, and the flexible cloth 1024 is located in the gap between the two groups of the limiting posts 1025 and is limited by the two groups of the flexible cloth 1024;

[0057] Among them, two groups of four limiting columns 1025 are tiltedly arranged on the support frame 1027 to form a rectangular distribution, and the limiter 1026 is arranged at the other end of the limiting column 1025, and a limiting groove with a width slightly larger than the width of the infusion bag is provided thereon, and the flexible cloth 1024 is located in the gap between the two groups of limiting columns 1025 and is limited by the limiting columns 1025. When the flexible cloth 1024 swings left and right with the mounting rod 1023, the movement range of the flexible cloth 1024 is limited by the limiting column 1025, and at the same time, the limiting groove of the limiter 1026 ensures that the infusion bag will not be subject to excessive resistance or deviate from the predetermined path when passing through;

[0058] In summary, when the motor 1013 is started, its driving shaft rotates and drives the transmission shaft 1 to rotate.

[0059] The rotation of the transmission shaft 1 causes the cam 1011 to perform periodic lifting and lowering motions, and the lifting and lowering of the cam 1011 is converted into the reciprocating swinging of the bat-shaped pendulum block 1022 through the hinged relationship between the connecting rod 1012 and the fixed block 1016; when the infusion bag enters the correction unit 100, its direction may deviate from the predetermined direction. At this time, the motor 1013 is started to drive the flexible cloth 1024 on the bat-shaped pendulum block 1022 to swing back and forth. The swinging of the flexible cloth 1024 and the contact with the infusion bag will generate friction, thereby guiding the infusion bag to move in the predetermined direction to achieve correction, so that the infusion bag is always facing the direction of the limiter 1026 with its head / tail. At the same time, the setting of the limit column 1025 and the limiter 1026 ensures that the infusion bag will not be subject to excessive resistance or deviate from the predetermined path during the correction process. The infusion bag after correction enters the transport screening unit 200, and the transport screening unit 200 screens and transports the infusion bag according to its direction.

[0060] Example 2

[0061] Reference Figures 1 to 8 , which is the second embodiment of the present invention, and this embodiment is implemented based on the previous embodiment;

[0062] The transport screening unit 200 includes a transport member;

[0063] The transporting member includes a conveyor belt 1 201 and a conveyor belt 202 arranged in parallel on the workbench, a conveyor belt 3 203 maintained perpendicular to the conveyor belt 1 201, a transporting portion that transports the infusion bags transported on the conveyor belt 1 201 to the conveyor belt 3 203 according to the screening results, and a screening component 206 located between the conveyor belt 1 201 and the conveyor belt 202 and used for screening infusion bags in different directions;

[0064] One end of the conveyor belt 1 201 away from the screening assembly 206 is connected to the discharge port of the limiter 1026 .

[0065] Among them, conveyor belt 1 201 and conveyor belt 2 202 are arranged in parallel on the workbench, and they are used to transport infusion bags; conveyor belt 3 203 is kept perpendicular to conveyor belt 1 201, and is used to transport the screened infusion bags to the designated location.

[0066] The conveyor belt 1 201 is provided with an acceleration part for accelerating the infusion bag, and the acceleration part is used to expand the distance between two adjacent infusion bags falling on the conveyor belt 1 201;

[0067] The acceleration part includes an auxiliary block 207 symmetrically arranged on the conveyor belt 201. The auxiliary block 207 is a trapezoidal structure. A mounting groove is opened on the auxiliary block 207. An electric roller 208 with a rotation speed greater than the transportation speed of the conveyor belt 201 is rotatably arranged in the mounting groove.

[0068] When the infusion bag on the conveyor belt 201 enters the auxiliary block 207, the electric roller 208 accelerates the infusion bag and expands the distance between adjacent infusion bags because its rotation speed is greater than the transportation speed of the conveyor belt 201.

[0069] The screening assembly 206 comprises a bearing rod 2062 disposed on a workbench, a bearing frame 2061 is disposed on the bearing rod 2062, a movable groove is provided on the bearing frame 2061, a conveying block 1 2063 and a conveying block 2064 are symmetrically disposed in the movable groove, and a driving member for driving the conveying block 1 2063 and the conveying block 2064 to move away from / approach each other is also disposed on the bearing frame 2061;

[0070] The driving member includes a rotating block 2067 rotatably arranged on the carrier 2061 via a connecting shaft, and a driving rod 1 2065 and a driving rod 2066 are respectively hingedly arranged on the rotating block 2067, the other end of the driving rod 1 2065 is hingedly connected to the conveying block 1 2063, and the other end of the driving rod 2 2066 is hingedly connected to the conveying block 2 2064;

[0071] When the rotating block 2067 rotates counterclockwise, the hinge of the second driving rod 2066 hinged to one side of the rotating block 2067 rises, and the second driving rod 2066 drives the hinge of the second conveying block 2064 to rotate counterclockwise along the rotating connection between the second conveying block 2064 and the carrier 2061. At the same time, when the rotating block 2067 rotates counterclockwise, the hinge of the driving rod 1 2065 on the other side of the rotating block 2067 descends, and the driving rod 1 2065 drives the hinge of the conveying block 1 2063 to rotate clockwise along the rotating connection between the conveying block 1 2063 and the carrier 2061.

[0072] The distance between the hinge of the driving rod 2066 and the hinge of the driving rod 1 2065 on the rotating block 2067 is 2d, the circumference of the shorter edge of the conveying block 1 2063 rotating at the rotating connection between the conveying block 1 2063 and the carrier 2061 is d, the circumference of the shorter edge of the conveying block 2064 rotating at the rotating connection between the conveying block 1 2063 and the carrier 2061 is d, the shorter side length of the conveying block 1 2063 is n1, the shorter side length of the conveying block 2064 is n2, the distance between the rotating connection between the conveying block 1 2063 and the carrier 2061 and the rotating connection between the conveying block 2 2064 and the carrier 2061 is N, n1>n2, and N=n1+n2, the length of the infusion bag is slightly smaller than n1+n2, when the rotating block 2067 is reversed When the needle rotates a quarter of a circle, the conveying block 1 2063 and the conveying block 2 2064 approach each other to form a clamping space. Because the length of n1+n2=N, the infusion bag will not fall out of the clamping space. At this time, the shorter side of the conveying block 1 2063 and the shorter side of the conveying block 2 2064 fit together. When the infusion bag is located in the clamping space between the conveying block 1 2063 and the conveying block 2 2064, the rotating block 2067 rotates in the opposite direction. At this time, the shorter side of the conveying block 1 2063 exceeds the center of gravity of the infusion bag. Therefore, the conveying block 1 2063 can transfer the infusion bag in the clamping space to the conveying block 1 2063. The longer side of the conveying block 1 2063 that rotates back to the original position is an inclined slope. Therefore, when returning to the original position, the infusion bag can slide from the longer side of the conveying block 1 2063 to the conveyor belt 2 202 for transportation.

[0073] The conveying block 1 2063 and the rotating block 2067 are rotatably connected to the carrier 2061 through a connecting shaft, one end of the rotating shaft passes through the carrier 2061 and is provided with a permanent magnet block 1 20671, a motor 20673 is fixed on one side of the carrier 2061, and a permanent magnet block 20672 is provided on the driving end of the motor 20673, and the permanent magnet block 20672 and the permanent magnet block 1 20671 are connected through magnetic coupling;

[0074] It also includes a button 2068 and a signal transmitter installed on the conveying block 2064. A signal receiver and a controller are provided in the rotating block 2067. When the button 2068 is squeezed, the signal is transmitted to the signal receiver through the signal transmitter, and the rotation direction of the rotating block 2067 is controlled by the controller.

[0075] The conveying block 1 2063 and the conveying block 2 2064 are both L-shaped structures, and the shorter sides of the conveying block 1 2063 and the conveying block 2 2064 are close to each other, and the longer sides are far away from each other;

[0076] In summary, when the protruding part of the head of the infusion bag is facing the screening component 206, because the length difference between the button 2068 and the wedge block 1 2069 is smaller than the head of the infusion bag, the head of the infusion bag abuts the button 2068 under the transportation of the conveyor belt 1 201, and when the button 2068 is pressed, the signal is transmitted and the rotating block 2067 is controlled by the controller to rotate, so that the conveying block 1 2063 is able to rotate and approach the conveying block 2 2064 under the rotation of the rotating block 2067, and at the same time, the conveying block 2064 also rotates and approaches the conveying block 1 2063 to form a clamping shape; at this time, the rotating block 2067 rotates in the opposite direction, and the conveying blocks 1 2063 and 2064 rotate in the opposite directions and move away from each other, and the infusion bag is transported to the conveyor belt 2 202 by the conveying block 1 2063, so that the infusion bag with its head facing the conveying block 2064 can be transported away.

[0077] Example 3

[0078] Reference Fig. 9 , which is the third embodiment of the present invention, is an infusion bag sorting device with a deviation correction function, which is implemented based on the infusion bag sorting device with a deviation correction function in embodiment 2, and includes:

[0079] The carrier frame 2061 is also symmetrically provided with a locking plate 20610, and the locking plate 20610 is provided with a square limiting groove. The conveying block 2064 is provided with a locking member that cooperates with the locking plate 20610 to lock or unlock according to the orientation of the infusion bag.

[0080] The locking member comprises a wedge block 1 2069 symmetrically and movably arranged on the conveying block 2064, the conveying block 2064 is also provided with a slide groove, a wedge block 20691 is slidably arranged in the slide groove, a limiting ring 20692 is arranged on the outer wall of the wedge block 20691 for preventing the wedge block 20691 from escaping from the conveying block 2064, a rectangular locking block 20694 is arranged at the other end of the limiting ring 20692, a spring 20693 is sleeved on the outer wall of the locking block 20694 and the spring 20693 is located between the limiting ring 20692 and the inner wall of the conveying block 2064 for assisting the locking member to reset;

[0081] One end of the wedge block 1 2069 is wedge-shaped against one end of the wedge block 2 20691 .

[0082] Among them, when the tail of the infusion bag is facing the delivery block 2064, because the length of the wedge block 1 2069 is greater than the length of the button 2068, the tail of the infusion bag first squeezes the two wedge blocks 1 2069, and when the wedge block 1 2069 is squeezed and moved by the infusion bag, it pushes the wedge block 20691 to slide, so that the locking block 20694 extends into the square limit groove of the locking plate 20610 to achieve locking. When locked, if the infusion bag continues to move forward When the button 2068 is pushed and squeezed, because the permanent magnet block 1 20671 and the permanent magnet block 2 20672 are magnetically coupled, the driving end of the motor 2 20673 drives the permanent magnet block 2 20672 to continue rotating, and does not cause damage to the motor 2 20673 itself; if the infusion bag is oriented with the head facing forward, the wedge block 1 2069 is not squeezed, the locking piece remains unlocked, and the operation of transferring to the conveyor belt 2 202 in Example 2 is continued.

[0083] The transporting part includes a support base 204 disposed on a workbench, and a mechanical arm 205 for transporting the infusion bag stopped on the second transport block 2064 is disposed on the support base 204;

[0084] A camera is provided on the clamping end of the mechanical arm 205. When the camera recognizes that an infusion bag stays on the conveying block 2064 for a long time, the mechanical arm 205 is driven to clamp and transport the infusion bag to the conveyor belt 3 203.

[0085] Among them, the camera continuously monitors the situation of the infusion bag on the conveying block 2064; if it is identified that an infusion bag stays on the conveying block 2064 for a long time, such as being locked due to incorrect orientation, the camera sends a signal to the control system; after receiving the signal, the control system drives the clamping end of the robotic arm 205 to move above the infusion bag and clamp the infusion bag; then, the robotic arm 205 moves the infusion bag to the conveyor belt 3 203 for subsequent operations.

[0086] In summary, through the cooperation between the locking parts and the transport parts, the automatic identification and screening of the orientation of the infusion bags and the automatic transport of infusion bags with different orientations are realized, thereby improving the automation level and screening efficiency of the overall equipment.
