Description

Technical Field

[0001] The present invention relates to the technical field of automatic bag-breaking machines, in particular to an automatic plasma bag-breaking machine and its usage method. Background Art

[0002] The plasma collected from healthy human bodies is contained in standard plasma bags and frozen into ice-like bodies for storage. Before producing blood products, the plasma bags that have been cleaned and disinfected need to be bag-broken so as to take out the ice-like plasma and put it into a plasma melting tank for melting.

[0003] In existing blood product manufacturing enterprises, the bag-breaking treatment of plasma bags is usually carried out manually, that is, a frozen plasma bag is grasped manually, cut with a knife, and then the ice-like plasma is squeezed out of the bag so that the ice-block plasma falls into a collection container. This not only takes a long time and has low efficiency, but also cannot ensure that the plasma blocks can fall smoothly after the plasma bag is cut, and is extremely likely to cause plasma pollution, and there is even a safety hazard that the operator may cut himself.

[0004] In the prior art, there are also bag-breaking machines that replace manual operations to perform automatic bag-breaking of plasma bags. The blade is driven by a power mechanism to make openings similar to a "cross" or "feng" character on the bottom surface of the plasma bag. During the process of plasma flowing out and falling, it is extremely easy to contact the surface of the opening of the cut plasma bag, resulting in plasma pollution. Moreover, since the plasma bag itself is made of a relatively soft plastic material, bag-cutting failure will also occur. Summary of the Invention

[0005] To solve the above problems, the present invention provides a plasma bag automatic bag-breaking machine with a reasonable structure and its usage method, thereby greatly improving the output, ensuring the quality, effectively reducing or even avoiding plasma pollution, and saving labor costs.

[0006] The technical solution adopted by the present invention is as follows:

[0007] An automatic plasma bag-breaking machine includes a machine base. A circular rail platform is convexly arranged in the middle of the machine base. A circumferential conveying component is installed along the circumference of the circular rail platform, and clamping mechanisms are installed at intervals on the circumferential conveying component. A circumferential groove is concavely arranged in the machine base outside the circular rail platform. A cutting station, a cutting detection station, a bag-clamping roller mechanism, and a waste bag recycling station are arranged in sequence along the circumferential groove.

[0008] As a further improvement of the above technical solution:

[0009] The circumferential groove includes a collection pool and a liquid collecting trough. The width and depth of the collection pool are both larger than the corresponding dimensions of the liquid collecting trough. The collection pool is located below the cutting station, the cutting detection station, and the bag-clamping roller mechanism. The collection pool penetrates through the machine base and is connected to a tank body groove.

[0010] The structure of the circular conveying assembly is as follows: it includes a track seat installed on the top of the circular track platform in the circumferential direction, the top surface of the track seat supports a circular track, and a clamping mechanism is installed on the circular track at intervals along the circumferential direction; a plurality of sprockets are installed at intervals on the circular track platform located on the inner side of the track seat, and a chain is installed around the plurality of sprockets, and one of the sprockets is dynamically connected to the conveying power; the clamping mechanism is fixed to the corresponding link of the chain.

[0011] V-shaped grooves are respectively provided on both sides of the annular track, and a guide wheel group is installed on the clamping mechanism, which is fitted into the V-shaped groove to form a sliding fit; lateral wheels are also installed on the clamping mechanism, and the circumferential surface of the lateral wheels is fitted on the side of the track seat.

[0012] The structure of the clamping mechanism is as follows: it includes a support installed on the annular conveying assembly, the support has a vertical wall extending toward the annular groove, a frame body is installed on the vertical wall, guide rods are installed on the upper and lower insides of the frame body, support plates are slidably installed on each guide rod, and elastic parts are respectively mounted on the guide rods located between the support plates and the inner wall of the frame body, and the elastic parts urge the upper and lower support plates to approach each other; L-shaped clamping arms are respectively installed on the same sides of the two support plates, and the horizontal arms of the two clamping arms approach each other for clamping.

[0013] The clamping mechanism is a non-powered clamping mechanism. A clamping and unlocking mechanism is respectively installed at the cutting station and the waste bag recycling station. The clamping and unlocking mechanism includes a horizontally laterally retractable inserting knife. The inserting knife is facing the gap between the upper and lower support plates, and the clamping of the clamping mechanism is unlocked by the clamping and unlocking mechanism.

[0014] The structure of the cutting station is as follows: it includes a cutting mechanism, a support seat is installed on the annular groove between the cutting mechanism and the corresponding clamping mechanism, the support seat supports the plasma bag, the end of the plasma bag with a tube extends between the upper cutter and the lower cutter of the cutting mechanism, and the other end of the plasma bag is clamped by the clamping mechanism; it also includes a bag pushing mechanism, which pushes the plasma bag on the support seat along the conveying direction.

[0015] The structure of the bag clamping roller mechanism is as follows: it includes a support seat, on which a bag clamping cylinder is installed, a horizontal cylinder is installed at the output end of the bag clamping cylinder, and a roller is installed at the output end of the horizontal cylinder through a roller frame for rotation; it also includes a bag clamping block fixed on the wall of the annular groove, and the roller and the bag clamping block are arranged opposite to each other.

[0016] The structure of the waste bag recycling station is as follows: it includes a bag collecting groove laterally connected to the annular groove, a baffle is installed along the cross-sectional direction of the bag collecting groove, and baffle bars are installed facing each other on the two side walls of the bag collecting groove where it connects with the annular groove; a side pushing mechanism is installed on the wall surface of the annular groove facing the bag collecting groove, and a downward pushing mechanism is also installed above the notch of the annular groove.

[0017] A method for using the automatic plasma bag opening machine comprises the following steps:

[0018] Place the plasma bag flat on the support seat, with the end of the plasma bag with the tube extending between the upper cutter and the lower cutter, and the other end of the plasma bag located at the clamping mechanism;

[0019] The end of the plasma bag is clamped by the clamping mechanism, and the upper cutter in the cutting mechanism moves downward relative to the lower cutter to cut the end of the plasma bag with the tube;

[0020] The blood plasma bag on the support seat is pushed out into the annular groove along the conveying direction by the bag pushing mechanism;

[0021] The end of the plasma bag is clamped by the clamping mechanism so that the cutout faces downward and the plasma in the plasma bag falls into the annular groove;

[0022] The annular conveying assembly drives the clamping mechanism holding the plasma bag to move from the cutting station to the cutting detection station, and determines whether the cutting is successful by collecting and judging the color of the plasma bag; if it is not cut, an alarm is sounded, and if it is cut, it continues to move to the bag clamping roller mechanism;

[0023] The roller in the bag clamping roller mechanism moves from top to bottom against the plasma bag, squeezing the residual liquid in the plasma bag downward into the annular groove;

[0024] The clamping mechanism drives the empty plasma bag to move to the waste bag recovery station for waste bag recovery.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The invention has a compact and reasonable structure. By automatically cutting the plasma bag, the liquid flows into the tank tank through the collection pool for collection, and the empty broken bags are automatically collected, which not only greatly improves the output and ensures the quality, but also effectively reduces or even avoids the plasma pollution and saves the labor cost. The arrangement and layout of the ring rail platform and the ring conveying components thereon are ingenious and compact, which realizes the rapid and automatic recycling of the clamping mechanism and facilitates the reasonable layout of each workstation. While ensuring the efficiency and effect, it effectively saves the occupied space and has good practicality.

[0027] The present invention also includes the following advantages:

[0028] The annular trough is divided into a liquid collection trough and a larger collection pool, which not only ensures the main liquid collection function of the collection pool, but also effectively avoids the influence of the liquid collection trough on the normal collection of liquid in the collection pool through the size difference. The residual liquid of the broken bag can also be reliably collected through the liquid collection trough and collected in the collection pool, reducing or even avoiding waste, and avoiding pollution caused by residual liquid dripping;

[0029] A cutting mechanism in the form of an upper cutter and a lower cutter is used to cut the end of the plasma bag, which effectively ensures the cutting effect and the size of the incision. After the plasma bag is pushed from a horizontal state to a vertical state by the bag pushing mechanism, the plasma clot can fall smoothly from the incision with almost no contact or contamination with the surface of the bag, effectively ensuring the cutting and breaking effect of the bag and ensuring the smooth and rapid separation of the plasma clot from the plasma bag.

[0048] The specific implementation of the present invention is described below in conjunction with the accompanying drawings.

[0049] like Figure 1 and Figure 2 As shown, the automatic blood plasma bag breaking machine of this embodiment includes a machine base 1, a circular track platform 2 is convexly arranged on the middle part of the machine base 1, a circular conveying assembly 40 is circumferentially installed along the circular track platform 2, and a clamping mechanism 4 is installed at intervals on the circular conveying assembly 40; the machine base 1 located on the outer side of the circular track platform 2 is concavely arranged with an annular groove 3, and a cutting station, a cutting detection station 7, a bag clamping roller mechanism 8, and a waste bag recovery station 9 are arranged in sequence along the annular groove 3.

[0050] In this embodiment, liquid is collected by automatically cutting the plasma bag 10, and the empty broken bag is automatically collected; the circular rail platform 2 and the annular conveying assembly 40 thereon are cleverly and compactly arranged, which realizes the rapid and automatic recycling of the clamping mechanism 4 and facilitates the reasonable layout of each workstation, effectively saving space while ensuring efficiency and effect.

[0051] The annular groove 3 includes a collecting pool 31 and a liquid collecting groove 32. The width and depth of the collecting pool 31 are both larger than the corresponding dimensions of the liquid collecting groove 32. The collecting pool 31 is located below the cutting station, the cutting detection station 7, and the bag clamping roller mechanism 8. The collecting pool 31 passes through the machine base 1 and is connected to the tank groove 33.

[0052] In this embodiment, the annular groove 3 is divided into a liquid collecting groove 32 and a larger collecting pool 31, which not only ensures the main liquid collection function of the collecting pool 31, but also effectively avoids the influence of the liquid collecting groove 32 on the normal collection of liquid in the collecting pool 31 through the size difference. The residual liquid of the broken bag can also be reliably collected through the liquid collecting groove 32 and collected in the collecting pool 31, reducing or even avoiding waste, and avoiding pollution caused by dripping residual liquid.

[0053] In this embodiment, the collecting pool 31 is connected to the tank body groove 33 behind the bag clamping roller mechanism 8, and the liquid is filled into the melt tank through the tank body groove 33; from the cutting station toward the bag clamping roller mechanism 8, the bottom surface of the collecting pool 31 is set to a downward inclined structure to effectively ensure that the plasma flows smoothly into the tank body groove 33.

[0054] A limit fence 30 is also installed on the wall of the annular groove 3 between the bag clamping roller mechanism 8 and the waste bag recovery station 9, so that the empty plasma bag 10 can be stably transported backwards by adhering to the wall of the annular groove 3, reducing the risk of the plasma bag 10 falling.

[0055] In actual use, the connection between the tank trough 33 and the collection pool 31 can be set as a detachable and movable assembly structure to facilitate the installation of the waste liquid tank 34 to replace the tank trough 33 at the end of the collection pool 31 for cleaning the collection pool 31.

[0056] In actual use, the liquid collection trough 32 can be set to a structural form inclined toward the collection pool 31, and the waste trough 61 at the cutting station and the bag collecting trough 91 at the waste bag recovery station 9 can also be set to a structural form inclined toward the collection pool 31 and the liquid collection trough 32, which is convenient for the collection of liquids and also facilitates all-round cleaning.

[0057] like Figure 3 As shown, the structure of the annular conveying assembly 40 is as follows: it includes a track seat 401 installed circumferentially on the top of the annular track platform 2, the top surface of the track seat 401 supports an annular track 403, and the annular track 403 is equipped with a clamping mechanism 4 that is slidably installed along the circumferential interval; a plurality of sprockets 402 are installed at intervals on the annular track platform 2 located on the inner side of the track seat 401, and the plurality of sprockets 402 are jointly surrounded by a chain 404, and one of the sprockets 402 is connected to the conveying power 405; the clamping mechanism 4 is fixed to the corresponding link of the chain 404.

[0058] In this embodiment, the conveying power 405 works to drive the chain 404 through the rotation of the sprocket 402 , and the clamping mechanism 4 moves along the annular track 403 with the transmission of the chain 404 .

[0059] V-shaped grooves 4031 are respectively provided on both sides of the annular track 403, and a guide wheel group 47 is installed on the clamping mechanism 4, which is fitted into the V-shaped groove 4031 to form a sliding fit. With the transmission of the chain 404, the guide wheel group 47 and the V-shaped groove 4031 form a moving guide for the clamping mechanism 4, which effectively ensures the stability and reliability of the movement of the clamping mechanism 4; the clamping mechanism 4 is also equipped with a lateral wheel 46, and the circumferential surface of the lateral wheel 46 is attached to the side of the track seat 401, further ensuring the stability of the movement of the clamping mechanism 4.

[0060] In this embodiment, the guide wheel group 47 may include a shaft mounted on the support 41 of the clamping mechanism 4, and the guide wheel is rotatably mounted on the bottom end of the shaft. The guide wheel is circumferentially fitted into the V-groove 4031. During the movement of the clamping mechanism 4, the guide wheel moves in the V-groove 4031.

[0061] like Figure 4 As shown, the structure of the clamping mechanism 4 is as follows: it includes a support 41 installed on the annular conveying assembly 40, the support 41 has a vertical wall extending toward the annular groove 3, a frame body 43 is installed on the vertical wall, guide rods 42 are installed on the upper and lower sides of the inner side of the frame body 43, and support plates 44 are slidably installed on each guide rod 42. Elastic parts are respectively mounted on the guide rods 42 located between the support plates 44 and the inner wall of the frame body 43, and the elastic parts urge the upper and lower support plates 44 to approach each other; L-shaped clamping arms 45 are respectively installed on the same side of the two support plates 44, and the horizontal arms of the two clamping arms 45 approach each other for clamping.

[0062] In this embodiment, the support 41 is fixed to the corresponding link of the chain 404 via the locking member 48 , so that the clamping mechanism 4 is driven to move synchronously via the transmission of the chain 404 .

[0063] In this embodiment, the clamping mechanism 4 is a non-powered clamping mechanism, and a clamping and unlocking mechanism 12 is respectively installed at the cutting station and the waste bag recovery station 9. The clamping and unlocking mechanism 12 includes a horizontally laterally retractable inserting knife, and the inserting knife is facing the gap between the upper and lower support plates 44, so that the horizontal arms of the upper and lower clamping arms 45 move away from each other up and down, and the clamping of the clamping mechanism 4 is unlocked by the clamping and unlocking mechanism 12.

[0064] In actual use, the clamping mechanism 4 can also be set as a self-powered mechanism, which can also achieve clamping and releasing of the plasma bag 10.

[0065] In this embodiment, the clamping mechanism 4 is configured as a non-powered clamping mechanism, and the clamping and unlocking mechanism 12 is arranged only at the position where clamping and unlocking are required, which effectively simplifies the structure, saves costs, and also realizes and ensures normal use.

[0066] like Figure 5As shown, the structure of the cutting station is as follows: it includes a cutting mechanism 6, a support seat 64 is installed on the annular groove 3 between the cutting mechanism 6 and the corresponding clamping mechanism 4, the support seat 64 supports the plasma bag 10, the end of the plasma bag 10 with the tube extends between the upper cutter 603 and the lower cutter 604 of the cutting mechanism 6, and the other end of the plasma bag 10 is clamped by the clamping mechanism 4; it also includes a bag pushing mechanism 63, which pushes the plasma bag 10 on the support seat 64 out along the conveying direction.

[0067] In this embodiment, a cutting mechanism 6 in the form of an upper cutting knife 603 and a lower cutting knife 604 is used to cut the end of the plasma bag 10, which effectively ensures the cutting effect and the size of the incision. After the plasma bag 10 is pushed from a horizontal state to a vertical state by the bag pushing mechanism 63, the plasma clot can fall smoothly from the incision with almost no contact or contamination with the surface of the bag body, effectively ensuring the cutting and breaking effect of the bag, and ensuring the smooth and rapid separation of the plasma clot from the plasma bag 10.

[0068] In this embodiment, the bag pushing mechanism 63 may include a linear force 631 fixed on the machine base 1 or the ring track table 2. The output part of the linear force 631 is equipped with a support arm 632. The end of the support arm 632 is equipped with a push rod 633. The push rod 633 is arranged along the width direction of the annular groove 3. Through the operation of the linear force 631, the push rod 633 facing the plasma bag 10 on the support seat 64 is driven to move along the length direction of the annular groove 3, thereby pushing the plasma bag 10 off the support seat 64. With the synchronous movement of the clamping mechanism 4 at the end of the plasma bag 10, the plasma bag 10 is turned from a horizontal state to a vertical state with the incision facing downward, and the plasma block can fall under the action of its own gravity.

[0069] like Figure 6 As shown, a cutting seat 602 is installed via an extension frame 600 fixed to the machine base 1, a cutting cylinder 601 is installed on the top of the cutting seat 602, the output end of the cutting cylinder 601 is downwardly facing and connected to an upper cutter 603, and cutting is achieved by the upper cutter 603 moving up and down and matching with the lower cutter 604; a guide structure for relative up and down movement can also be provided between the upper cutter 603 and the lower cutter 604.

[0070] like Figure 7 As shown, a waste trough 61 is installed behind the upper cutter 603 and the lower cutter 604, and a plurality of discharge rods 611 are arranged on the waste trough 61 along the width direction. The discharge rods 611 support the tube-edge bag 101 cut from the plasma bag 10, and the end of the waste trough 61 is connected to the waste collection frame 62; as the cutting proceeds, the tube-edge bag 101 moves backwards via the discharge rods 611 to be discharged into the waste collection frame 62.

[0071] like Figure 8As shown, the structure of the bag clamping roller mechanism 8 is: it includes a support seat 81, on which a bag clamping cylinder 82 is installed, and a horizontal cylinder 83 is installed at the output end of the bag clamping cylinder 82, and a roller 85 is rotatably installed at the output end of the horizontal cylinder 83 through a roller frame 84; it also includes a bag clamping block 80 fixed on the wall of the annular groove 3, and the roller 85 is arranged opposite to the bag clamping block 80.

[0072] When the clamping mechanism 4 holding the plasma bag 10 moves to the bag clamping block 80, the plasma bag 10 is located on the surface of the bag clamping block 80, and the horizontal cylinder 83 works to make the roller 85 move along the width direction of the annular groove 3 to approach and fit the plasma bag 10 on the surface of the bag clamping block 80, and then the bag clamping cylinder 82 works to drive the roller 85 to move from top to bottom in contact with the plasma bag 10, thereby squeezing the plasma clots or liquid in the plasma bag 10 downward through the lower incision, making the plasma bag 10 an empty bag, effectively reducing the liquid residue in the plasma bag 10.

[0073] like Fig. 9 As shown, the structure of the waste bag recovery station 9 is as follows: it includes a bag collecting groove 91 laterally connected to the annular groove 3, a baffle 92 is arranged along the cross-sectional direction of the bag collecting groove 91, and baffle bars 95 are installed facing each other on the two side walls of the bag collecting groove 91 at the junction with the annular groove 3; a side pushing mechanism 93 is installed on the wall surface of the annular groove 3 facing the bag collecting groove 91, and a downward pushing mechanism 94 is also installed above the notch of the annular groove 3.

[0074] In this embodiment, when the clamping mechanism 4 moves to the waste bag recovery station 9, the clamping unlocking mechanism 12 unlocks the clamping mechanism 4 for the empty plasma bag 10, the pushing mechanism 94 works to push the plasma bag 10 downward away from the clamping mechanism 4, and the side pushing mechanism 93 works to push the plasma bag 10 laterally into the bag collecting trough 91; the setting of the baffle 95 effectively blocks and prevents the plasma bag 10 entering the bag collecting trough 91 from returning and falling into the annular groove 3. Combined with the setting of the baffle 92, the orderly and reliable collection of the empty plasma bags 10 in the bag collecting trough 91 is effectively guaranteed.

[0075] In this embodiment, a cleaning pipeline 100 can also be arranged above the annular groove 3. The cleaning pipeline 100 is connected to an external water source or cleaning liquid. The cleaning pipeline 100 is arranged with multiple water outlet nozzles toward the annular groove 3 to clean the annular groove 3, and the waste liquid after cleaning is discharged into the waste liquid tank 34 through the connection between the waste liquid tank 34 and the collection tank 31.

[0076] In this embodiment, an isolation and protection cabin 11 may be installed above the machine base 1 to isolate and protect the bag breaking process.

[0077] The method for using the automatic blood plasma bag opening machine of this embodiment comprises the following steps:

[0078] Step 1: Place the plasma bag 10 flat on the support seat 64, with the end of the plasma bag 10 with the tube extending between the upper cutter 603 and the lower cutter 604, and the other end of the plasma bag 10 located at the clamping mechanism 4;

[0079] In this embodiment, an automatic feeding mechanism 5 , such as a robot, may be provided in front of the cutting station, and the plasma bag 10 may be grasped or adsorbed by the robot and placed stably and horizontally on the support seat 64 .

[0080] Of course, the plasma bag 10 can also be loaded onto the support seat 64 manually or in other ways.

[0081] Step 2: The end of the plasma bag 10 is clamped by the clamping mechanism 4, and the upper cutter 603 in the cutting mechanism 6 moves downward relative to the lower cutter 604 to cut the end of the plasma bag 10 with the tube; the tube-edged bag 101 cut off from the end of the plasma bag 10 is supported by the discharge rod 611 on the waste trough 61 and finally collected in the waste collection frame 62.

[0082] Step 3: The bag pushing mechanism 63 pushes the plasma bag 10 on the support seat 64 into the annular groove 3 along the conveying direction;

[0083] In this embodiment, the linear force 631 drives the push rod 633 which is laterally facing the plasma bag 10 on the support seat 64 to move along the length direction of the annular groove 3, thereby pushing the plasma bag 10 off the support seat 64.

[0084] Step 4: The end of the plasma bag 10 is clamped by the clamping mechanism 4 and is in an upright state with the cutout facing downward, and the plasma in the plasma bag 10 falls into the annular groove 3.

[0085] Step 5: The annular conveying assembly 40 drives the clamping mechanism 4 holding the plasma bag 10 to move from the cutting station to the cutting detection station 7, and determines whether the cutting is successful by collecting and judging the color of the plasma bag; if it is not cut, an alarm is issued and it is processed manually; if it is cut, it continues to move to the bag clamping roller mechanism 8.

[0086] In this embodiment, the cutting detection station 7 can adopt the existing mature visual inspection device, which can not only judge by the color of the plasma bag, but also judge whether the plasma bag is cut based on the image of the bag shape, and can also judge whether the plasma bag is stably clamped on the clamping mechanism 4 based on the image, so as to facilitate the timely handling of abnormal situations.

[0087] Of course, in actual use, the cutting detection station 7 can also adopt detection methods other than visual detection devices according to needs, such as recognition sensors that can distinguish colors, etc., to determine whether the plasma bag 10 is broken and satisfy the use.

[0088] Step 6: The roller 85 in the bag clamping roller mechanism 8 moves from top to bottom against the plasma bag 10 to squeeze the residual liquid in the plasma bag 10 downward into the annular groove 3;

[0089] When the clamping mechanism 4 holding the plasma bag 10 moves to the bag clamping block 80, the plasma bag 10 is located on the surface of the bag clamping block 80, and the horizontal cylinder 83 works to make the roller 85 move along the width direction of the annular groove 3 to approach and fit the plasma bag 10 on the surface of the bag clamping block 80, and then the bag clamping cylinder 82 works to drive the roller 85 to move from top to bottom in contact with the plasma bag 10, thereby squeezing the plasma clots or liquid in the plasma bag 10 downward through the lower incision.

[0090] Step 7: The clamping mechanism 4 drives the empty plasma bag 10 to move to the waste bag recovery station 9 for waste bag recovery;

[0091] When the clamping mechanism 4 moves to the waste bag recovery station 9, the clamping unlocking mechanism 12 unlocks the clamping mechanism 4 from clamping the empty plasma bag 10, the pushing-down mechanism 94 works to push the plasma bag 10 downward away from the clamping mechanism 4, and the side pushing mechanism 93 works to push the plasma bag 10 sideways into the bag collecting trough 91.

[0092] The overall layout of the present invention is reasonable and ingenious, and occupies a small space. While realizing reliable and effective bag breaking of plasma bags, it greatly improves the output, ensures the quality, effectively reduces or even avoids plasma contamination, and saves labor costs.

[0093] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0094] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any form of modification may be made within the scope of protection of the present invention.
