[0036] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0037] Unless otherwise specified or defined, the "first, second..." used in this article is merely used to distinguish names and does not represent a specific quantity or order.

[0038] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.

[0040] It should be noted that the automatic bag opening machine 100 is used to automatically open the material bag 200 containing the material. Specifically, in this embodiment, the automatic bag opening machine 100 is used to remove the collection tube 202 containing the virus specimen from the bag body 201 and automatically separate and collect the collection tube 202 and the bag body 201. Of course, in other embodiments, the automatic bag opening machine 100 can also be used to automatically open the bag of other materials and the bag body 201, and there is no special limitation here. For the convenience of description, the following mainly describes the automatic opening of the collection tube 202.

[0041] The present invention provides an automatic bag opening machine 100, such as Figures 1 to 7 As shown, it is used to automatically unpack a material bag 200, wherein the material bag 200 refers to a structure in which the material is encapsulated in a bag body 201, which includes the material and the bag body 201. The automatic bag unpacking machine 100 includes a feeding mechanism 1, a positioning mechanism 2, a conveying mechanism 3, a cutting mechanism 4 and a separating mechanism 5;

[0042] The loading mechanism 1 is disposed above the positioning mechanism 2 ; the loading mechanism 1 is used to load the material bag 200 and transfer the material to the positioning mechanism 2 .

[0043] The positioning mechanism 2 includes a placement table 21 and a first extruding member 22. The loading mechanism 1 transfers the material to the placement table 21. The first extruding member 22 is movably arranged on the placement table 21 and there is a first gap between the placement table 21. The first extruding member 22 pushes the material bag 200 when it moves relative to the placement table 21, so as to position the material in the material bag 200, such as the collection tube 202, relative to the bag body 201 and push the material bag 200 to the conveying mechanism 3; specifically, since the collection tube 202 may be in any position relative to the bag body 201 in the initial state, such as being located at the center of the bag body 201, or being placed obliquely in the bag body 201, in order to facilitate the next step of conveying and cutting operations, it is necessary to position the collection tube 202 in the bag body 201 Processing, wherein a first extruding member 22 is movably arranged on the placement table 21 and there is a first gap between the first extruding member 22 and the placement table 21, wherein the height of the first gap is greater than the thickness of the bag body 201 and less than the thickness of the collection tube 202, so when the first extruding member 22 moves relative to the placement table 21, the bag body 201 can pass through the first gap, while the collection tube 202 cannot pass through the first gap, thereby pushing the collection tube 202, so that the collection tube 202 moves relative to the bag body 201 in the bag body 201 to the side position of the bag body 201, and then the collection tube 202 is in a relatively static state in the bag body 201. At this time, the first extruding member 22 continues to push the collection tube 202 so that the collection tube 202 drives the bag body 201 to move from the placement table 21 to the conveying mechanism 3 for further transmission.

[0044] The cutting mechanism 4 is movably arranged on one side of the conveying mechanism 3, and is used for cutting the bag body 201 to form a cutting opening in the bag body 201, that is, when the conveying mechanism 3 conveys the material bag 200 to the bottom of the cutting mechanism 4, the cutting mechanism 4 cuts a cutting opening in the bag body 201. At this time, the material such as the collection tube 202 is still located in the bag body 201, but the bag body 201 is no longer in a sealed state, but has a cutting opening, wherein the size of the cutting opening should be sufficient to ensure that the collection tube 202 can be separated from the bag body 201.

[0045] The separation mechanism 5 includes a conveying table 51 and a second extrusion member 52. The conveying table 51 is located at the end of the conveying mechanism 3, and the second extrusion member 52 is spatially arranged on opposite sides of the conveying mechanism 3 with the cutting mechanism 4; there is a second gap between the second extrusion member 52 and the table surface of the conveying table 51, and the conveying table 51 conveys the material bag 200 in the direction of the second extrusion member 52. When the material bag 200 formed with the cutting opening is transported from the conveying mechanism 3 to the conveying platform 51, the conveying platform 51 transports the material bag 200 to the second extrusion member 52. Since the second extrusion member 52 is spatially arranged on the opposite sides of the conveying mechanism 3 with the cutting mechanism 4, it should be noted that the second extrusion member 52 and the cutting mechanism 4 are arranged on the opposite sides of the conveying mechanism 3, which means that the second extrusion member 52 and the cutting mechanism 4 are respectively located on the first side of the conveying mechanism 3 along its own conveying direction and the second side opposite to the first side, but does not limit the specific positions of the second extrusion member 52 and the cutting mechanism 4 on the opposite sides of the conveying mechanism 3; therefore, the side of the bag body 201 with the cutting opening faces away from the second extrusion member 52, and since the second gap height of the second extrusion member 52 is greater than that of the bag body The thickness of 201 is less than the thickness of the material such as the collecting tube 202. Therefore, when the conveying platform 51 conveys the material bag 200, the bag body 201 can pass through the second gap, while the collecting tube 202 cannot pass through the second gap, thereby pushing the collecting tube 202 to make the collecting tube 202 and the bag body 201 move relative to each other, and the collecting tube 202 rolls out from the cutting opening of the bag body 201, and the bag body 201 continues to move along the movement trajectory of the conveying platform 51. The collecting tube 202 is blocked by the second squeezing member 52 and remains on the conveying platform 51. Since the collecting tube 202 can form inertia when being conveyed by the conveying mechanism 3, it can continue to move from the conveying platform 51 along the extension direction of the movement trajectory of the conveying mechanism 3. Therefore, a collecting device can be set at the end of the conveying platform 51 to collect the conveyed collecting tube 202.

[0046] According to the above, the working principle of the automatic bag opening machine 100 is roughly as follows:

[0047] The material bag 200 is transferred to the placement table 21 of the positioning mechanism 2 by the loading mechanism 1;

[0048] After the placing table 21 of the positioning mechanism 2 receives the material bag 200, the first extruding member 22 moves relative to the placing table 21 and pushes the material in the material bag 200 relative to the bag body 201 to move to one side of the bag body 201, and pushes the material bag 200 to the conveying surface of the conveying mechanism 3;

[0049] The conveying mechanism 3 conveys the material to the cutting mechanism 4, and the cutting mechanism 4 cuts the bag body 201 to form a cutting opening, and then continues to convey the material to the conveying platform 51 of the separation mechanism 5;

[0050] After the conveying platform 51 receives the cut material bag 200, the conveying platform 51 drives the material bag 200 to move in the direction of the second extrusion member 52. The second extrusion member 52 squeezes the material bag 200 and separates the material from the cutting opening relative to the bag body 201. The bag body 201 continues to move along the movement trajectory of the conveying platform 51. The material is blocked by the second extrusion member 52 and remains on the conveying platform 51 and continues to move forward along the extension direction of the movement trajectory of the conveying mechanism 3 through the conveying platform 51.

[0051] In summary, the automatic bag opening machine 100 cooperates with the feeding mechanism 1, the positioning mechanism 2, the conveying mechanism 3, the cutting mechanism 4 and the separating mechanism 5 to automatically load, position, convey, cut and automatically separate the bag body 201 and the material of the material bag 200 after the material is encapsulated in the bag body 201, such as the collection tube 202. The material bag 200 is automatically loaded to the positioning mechanism 2 by the feeding mechanism 1, the positioning mechanism 2 positions the position of the material in the bag body 201 and pushes it to the conveying mechanism 3 for further transmission. The material bag 200 is cut by the cutting mechanism 4 to form a cutting opening during the conveying process of the conveying mechanism 3 and is then conveyed to the separating mechanism 5. The separating mechanism 5 separates the bag body 201 and the material in the material bag 200 to automatically collect the material after the bag is opened. Therefore, the automatic bag unpacking machine 100 can automatically unpack materials packaged in the bag body 201, such as the collection tube 202, and automatically separate the collection tube 202 from the bag body 201, so as to automatically collect the unpacked collection tube 202 without manual bag unpacking, thereby reducing labor costs and improving work efficiency.

[0052] In some embodiments, Figure 1 As shown, the automatic bag opening machine 100 further includes a mounting frame 7, and the feeding mechanism 1, the positioning mechanism 2, the conveying mechanism 3, the cutting mechanism 4 and the separating mechanism 5 are all adapted to be arranged on the mounting frame 7 to make the structure compact.

[0053] In some embodiments, Figure 3 and Figure 4As shown, the first extrusion member 22 includes a first driving device 221, a first connecting member 222 and a first rolling body 223; the output end of the first driving device 221 is connected to the first connecting member 222 and drives the first connecting member 222 to reciprocate above the placement table 21, and the first rolling body 223 is rotatably mounted on the first connecting member 222, and there is a first gap between the first rolling body 223 and the placement table 21. Specifically, the first driving device 221 can be a linear motor module or a linear driving device such as an electric cylinder, and no special limitation is made here; the first driving device 221 drives the first connecting member 222 to reciprocate above the placement table 21, thereby driving the first rolling body 223 to reciprocate above the placement table 21, wherein the first rolling body 223 is arranged parallel to the table surface of the placement table 21 such as a roller, so that the first rolling body 223 maintains the same distance with the placement table 21 during the reciprocating movement above the placement table 21, and the first rolling body 223 moves toward the conveyor. When the bag 201 moves in the direction of the conveying mechanism 3, since there is a first gap between the first rolling body 223 and the placing table 21, the bag 201 can pass through the first gap, but the collecting tube 202 cannot pass through the first gap, so the first rolling body 223 rotates and pushes the collecting tube 202, so that the collecting tube 202 moves relative to the bag body 201 to the side position of the bag body 201 in the bag body 201 for adjustment. After the adjustment is completed, the first rolling body 223 continues to push the collecting tube 202 so that the collecting tube 202 drives the bag 201 to move from the placing table 21 to the conveying mechanism 3 for further transmission.

[0054] Specifically, the first connecting member 222 includes a vertical plate and a horizontal plate connected to the top of the vertical plate, the first driving device 221 is arranged on the side of the placing table 21, the bottom of the vertical plate is arranged on the output end of the first driving device 221, the horizontal plate is provided with a hanging frame, and the first rolling body 223 is passed through the hanging frame and can roll relative to the hanging frame. The placing table 21 is a rectangular table body, the length of the first rolling body 223 is consistent with the length of the long end of the placing table 21, and the first rolling body 223 is arranged above the placing table 21 along the long end direction of the placing table 21, and the first rolling body 223 reciprocates along the short end direction of the placing table 21.

[0055] In some embodiments, Figure 3 As shown, a baffle 31 is provided on the side of the conveying mechanism 3 opposite to the placement table 21 and away from the placement table 21. The baffle 31 can limit the material bag 200 transferred from the placement table 21 to the conveying mechanism 3, so as to prevent the first extrusion member 22 from pushing the material bag 200 away from the conveying mechanism 3. In addition, guide plates 32 can also be provided on opposite sides of the conveying surface of the conveying mechanism 3. The guide plates 32 are in an arc shape or a relatively inclined structure, so that the material bag 200 is guided and conveyed to the middle position along the guide plates 32, so as to prevent the material bag 200 from deviating during the conveying process.

[0056] In some embodiments, Figure 2 and Figure 6 As shown, the second extrusion member 52 includes a second connection member 521 and a second rolling body 522, the second connection member 521 is arranged at the end of the motion track of the conveying platform 51, the second rolling body 522 is rotatably sleeved on the second connection member 521, and a second gap exists between the second rolling body 522 and the table surface of the conveying platform 51. The material bag 200 with the cutout formed therein is conveyed to the conveying platform 51 by the conveying mechanism 3, so that the material bag 200 can be conveyed to the conveying platform 51 in an orderly manner, so that the second extrusion member 52 can separate the bag body 201 and the material in the material bag 200 in an orderly manner. Specifically, by arranging a second rolling body 522 such as a roller above the conveying platform 51, when the conveying platform 51 conveys the material bag 200 to the second rolling body 522, the conveying platform 51 continues to convey, which can drive the second rolling body 522 to roll. Under the combined action of the conveying of the conveying platform 51 and the rolling of the second rolling body 522, the material such as the collection tube 202 can be pushed out from the cut on the bag body 201, and the bag body 201 continues to move along the movement trajectory of the conveying platform 51. The collection tube 202 is blocked by the second rolling body 522 and remains on the conveying platform 51, thereby realizing automatic separation of the bag and the tube. In addition, it should be noted that the second rolling body 522 can be fixedly arranged at a height relative to the conveying platform 51, or can be telescopically moved in the up-and-down direction above the conveying platform 51 to adjust the gap between the second rolling body 522 and the conveying platform 51 to adapt to the sizes of different collection tubes 202.

[0057] In some embodiments, the outer surface of the second rolling body 522 is a surface with friction, and the friction of the surface can be increased by using stripes or corrugated structures, or by increasing the roughness of the surface, etc.

[0058] In some embodiments, the second rolling body 522 can be fixedly mounted on the second connecting member 521, or can be detachably mounted on the second connecting member 521, so that second rolling bodies 522 of different specifications can be replaced according to the size of the collection tube 202, thereby improving the bag-tube separation efficiency.

[0059] In some embodiments, Figure 6 As shown, the conveying platform 51 is tilted along the conveying path of the conveying mechanism 3, and the height of the end of the conveying platform 51 close to the conveying mechanism 3 is higher than the height of the end of the conveying platform 51 away from the conveying mechanism 3. The tilted conveying platform 51 can make the collection tube 202 move downward along the tilted platform surface of the conveying platform 51 under the action of the second extruding member 52 and the inertia of the conveying of the conveying mechanism 3, combined with the gravity of the collection tube 202 itself, so as to be separated from the bag body 201 and fall at the end of the conveying platform 51, and the fallen collection tube 202 can be automatically collected.

[0060] In some embodiments, the conveyor platform 51 may be a conveyor belt, and the conveying method thereof may be a mesh chain conveyor, a belt conveyor, or a cloth belt conveyor. The conveyor platform 51 may convey a plurality of material bags 200 at the same time.

[0061] In some embodiments, the second connecting member 521 includes a truss and two connecting rods disposed at both ends of the truss, one end of the two connecting rods is elastically connected to the truss, and the other end of the two connecting rods is connected to the roller of the second rolling body 522.

[0062] In some embodiments, a receiving device (not shown) for receiving the collection tube 202 is provided near the lowest end of the conveying platform 51. The receiving device is a receiving box or a receiving transmission line. When the receiving device is a receiving box, the receiving box needs to be manually removed to take out the collection tube 202 for the next process. When the receiving device is a receiving transmission line, the separated collection tube 202 can be orderly transmitted to the next process.

[0063] In some embodiments, Figure 2 , Figure 5 and Figure 6 As shown, the automatic bag opening machine 100 also includes a guide mechanism 6, which is arranged above the conveying surface of the conveying mechanism 3, and the guide mechanism 6 is arranged opposite to the cutting mechanism 4. The guide mechanism 6 has a guide channel, and the guide channel is used for the material in the material bag 200 to pass through. Among them, in this embodiment, the conveying mechanism 3 is a conveyor belt, and the material bag 200 is conveyed to the guide mechanism 6 through the conveying mechanism 3. The guide channel of the guide mechanism 6 is adapted to the shape and size of the material in the material bag 200, such as the collection tube 202, wherein the collection tube 202 and the bag body 201 covering the collection tube 202 can pass through the guide channel, and the remaining bag body 201 is located on the outside of the guide channel. Therefore, when the bag body 201 equipped with the collection tube 202 passes through the guide mechanism 6, the collection tube 202 and the bag body 201 covering the collection tube 202 pass through the guide channel. At the same time, the remaining bag body 201 located on the outside of the guide channel touches the cutting mechanism 4, and the cutting mechanism 4 cuts the bag body 201 to form a cutting opening. The collection tube 202 and the bag body 201 covering the collection tube 202 continue to be transported backward along the guide channel, thereby completing the bag cutting and guiding process of the bag body 201 equipped with the collection tube 202.

[0064] In some embodiments, Figure 2 and Figure 5As shown, the guide mechanism 6 includes a first bracket 61 and a guide wheel 62. The guide wheel 62 is rotatably arranged on the first bracket 61, and the guide wheel 62 is located on the conveying surface of the conveying mechanism 3. The guide wheel 62 is provided with a guide groove 621 along its own circumferential direction, and the guide groove 621 is a guide channel. The guide groove 621 provided on the guide wheel 62 is adapted to the shape and size of the collection tube 202. Under the combined action of the conveying of the conveying mechanism 3 and the rotation of the guide wheel 62, the collection tube 202 can be continuously conveyed backward along the direction of the guide groove 621. In addition, in some embodiments, the guide groove 621 is concave toward the central axis of the guide wheel 62 to form an arc groove, which can be adapted to the shape of the collection tube 202 to avoid collision with the collection tube 202.

[0065] In some embodiments, Figure 5 As shown, a plurality of guide wheels 62 are provided, and each guide wheel 62 is arranged in sequence along the extension direction of the motion trajectory of the conveying mechanism 3. The width of the guide groove 621 of the guide wheel 62 located at the first position and close to one end of the positioning mechanism 2 is greater than the width of the guide grooves 621 of the remaining guide wheels 62. The plurality of guide wheels 62 cooperate with each other, and the width of the guide grooves 621 becomes narrower in sequence, which can further limit the guiding conveying of the collection tube 202, improve the guiding effect, and effectively prevent the material bag 200 from being deflected and causing material jamming when it reaches the separation mechanism 5.

[0066] In some embodiments, Figure 2 As shown, the guide mechanism 6 further includes a fourth driving device 63 disposed on the first bracket 61. The output end of the fourth driving device 63, such as a rotating motor, is connected to the guide wheel 62 and drives the guide wheel 62 to rotate, so that the guide wheel 62 can adjust the rotation speed according to the conveying speed of the conveying mechanism 3, so as to cooperate with the conveying mechanism 3 to allow the collection tube 202 and the bag body 201 covered on the collection tube 202 to continue to be conveyed backward along the guide groove 621. In addition, when multiple guide wheels 62 are provided, the multiple guide wheels 62 can be connected to a rotating motor through a transmission mechanism, so that the multiple guide wheels 62 can be driven to rotate synchronously by one rotating motor, thereby improving the compactness of the structure and the synchronization of movement.

[0067] In some embodiments, Figure 2 and Figure 7As shown, the feeding mechanism 1 includes a second driving device 11, a gripper 12, a material box 13 and a camera 14; the output end of the second driving device 11 is connected to the gripper 12 and drives the gripper 12 to move between the material box 13 and the placement table 21, and the camera 14 is arranged above the material box 13 and is used to determine the position of the material bag 200 in the material box 13. Specifically, the camera 14 is arranged above the material box 13 to take pictures and perform image processing to obtain the position of the material bag 200 in the material box 13, so that the position of the material bag 200 can be obtained conveniently and quickly, so that when the gripper 12 grips the next material bag 200, the second driving device 11 can accurately drive the gripper 12 to the position of the next material bag 200 and grip the material bag 200 and transfer it to the placement table 21 for positioning, which can improve the efficiency of gripping. The second driving device 11 can be a multi-axis linkage driving device, which can drive the gripper 12 to rotate up, down, left, and right, and the gripper 12 can be a conventional clamping claw structure. In addition, the material box 13 may also be a lifting material box so that it can rise to replenish its height after clamping the material bags 200 multiple times.

[0068] In some embodiments, Figure 2 and Figure 5 As shown, the cutting mechanism 4 includes a second bracket 41, a cutting wheel 42 and a third driving device 43; the second bracket 41 is arranged on one side of the conveying mechanism 3, the cutting wheel 42 is rotatably arranged on the second bracket 41 and is located on the conveying surface of the conveying mechanism 3, and the output end of the third driving device 43 is connected to the cutting wheel 42 and drives the cutting wheel 42 to rotate around its own central axis. In this embodiment, the third driving device 43 can be a rotating motor, the output end of the rotating motor is connected to the cutting wheel 42 and drives the cutting wheel 42 to rotate, and the cutting wheel 42 can synchronously cut the bag passing on the conveying mechanism 3 during the rotation process.

[0069] In addition, it should be noted that the automatic bag opening machine 100 also includes a controller or other related components for automatically controlling the loading mechanism 1, the positioning mechanism 2, the conveying mechanism 3, the cutting mechanism 4, the separation mechanism 5 and the guiding mechanism 6 to move according to a preset program, so as to realize multiple automated processing of materials. Various technical solutions known to ordinary technicians in this field now and in the future can be adopted, which will not be described in detail here.

[0070] The present invention also provides a control method of an automatic bag opening machine 100, including the automatic bag opening machine 100 described above, and the control method includes the following steps:

[0071] The material bag 200 is transferred to the placement table 21 of the positioning mechanism 2 by the loading mechanism 1;

[0072] After the placing table 21 of the positioning mechanism 2 receives the material bag 200, the first extruding member 22 moves relative to the placing table 21 and pushes the material in the material bag 200 relative to the bag body 201 to move to one side of the bag body 201, and pushes the material bag 200 to the conveying surface of the conveying mechanism 3;

[0073] The conveying mechanism 3 conveys the material to the cutting mechanism 4, and the cutting mechanism 4 cuts the bag body 201 to form a cutting opening, and then continues to convey the material to the conveying platform 51 of the separation mechanism 5;

[0074] After receiving the cut material bag 200, the conveying platform 51 drives the material bag 200 to move in the direction of the second extruding member 52. The second extruding member 52 squeezes the material bag 200 and separates the material from the cutting opening relative to the bag body 201. The bag body 201 continues to move along the movement trajectory of the conveying platform 51. The material is blocked by the second extruding member 52 and remains on the conveying platform 51. It continues to move forward along the extension direction of the movement trajectory of the conveying mechanism 3 through the conveying platform 51.

[0075] In summary, the control method of the automatic bag opening machine 100 can automatically load, position, convey, cut and automatically separate the bag body 201 and the material after the material is packaged in the bag body 201 by controlling the loading mechanism 1, the positioning mechanism 2, the conveying mechanism 3, the cutting mechanism 4 and the separation mechanism 5. Therefore, the automatic bag opening machine 100 can automatically unpack the material packaged in the bag body 201, such as the collection tube 202, and automatically separate the collection tube 202 and the sealing bag 201, so as to automatically collect the unpacked collection tube 202 without manual bag unpacking, thereby reducing labor costs and improving work efficiency.

[0076] The above embodiments are not exhaustive enumerations of the present invention, and there may be multiple other implementations not listed. Any replacement and improvement made without violating the concept of the present invention shall fall within the protection scope of the present invention.
