Description

Technical Field

[0001] This invention relates to the technical field of material transfer, and in particular to a non-standard tube conveying system. Background Technology

[0002] The rapid development of molecular biology has brought about many new technologies, one of which is eight-tube PCR. PCR (polymerase chain reaction), as an important molecular biology tool, is widely used for DNA amplification and detection. Eight-tube PCR, as a variant of PCR, provides scientists with a more efficient and accurate method for DNA amplification and analysis, greatly advancing research in the field of molecular biology.

[0003] The PCR tubes (also known as PCR reaction tubes or test tubes) used in PCR technology are made of medical-grade high-transparency polypropylene. Their smooth surface ensures high efficiency and uniformity between samples, meeting the requirements for accurate and efficient PCR reactions. They are used in fields such as gene detection, disease diagnosis, and drug development.

[0004] These irregularly shaped tubes face many difficulties in transporting on assembly lines due to their bottle diameter-to-height ratio, light weight, and non-flat bottom. Moreover, these irregularly shaped tubes are generally made of plastic-like materials, which are prone to deformation and have inaccurate bottle mouth positioning, causing many problems for subsequent filling and other processes.

[0005] Existing shaped pipe conveying systems are prone to deformation during the conveying of shaped pipes. Qualified shaped pipes are typically multi-unit pipes, and the openings of each smaller pipe should be flush. Figure 1 The eight-tube joint shown is prone to deformation and becoming Figure 2 and Figure 3 This condition can easily lead to filling errors during subsequent filling processes. Summary of the Invention

[0006] The purpose of this invention is to provide a non-standard tube conveying system to solve the problem that non-standard tubes are easily deformed when conveying them in existing non-standard tube conveying systems.

[0007] To solve the above-mentioned technical problems, the present invention provides a non-standard tube conveying system.

[0008] The irregular tube conveying system of the present invention includes:

[0009] The tube handling device is used to comb irregularly shaped tubes into a radially upward, queued arrangement and then export them.

The platform is fixedly connected to the base and is used to support the shaping modules. The pusher is located above the platform and is used to periodically push multiple shaping modules forward. The traction device is used to push the pusher forward or backward periodically to convey the shaping modules. The tilting device is used to rotate the pusher before it moves backward so as to avoid the shaping modules during the backward movement.

[0017] Furthermore, the pusher platform is provided with a plurality of equally spaced slots, which are used to accommodate the shaping module so as to push the shaping module through the slot wall.

[0018] Furthermore, the base is provided with a slide rail, the pusher platform is rotatably connected to the slide rail and can slide along the guide of the slide rail, and the output end of the traction device is connected to the pusher platform to push the pusher platform forward or backward periodically.

[0019] Furthermore, the slide rail includes a frame and a rotating shaft disposed on the frame, and the pusher table is hinged to the rotating shaft and can slide along the rotating shaft.

[0020] Furthermore, one end of the flipping device is hinged to the base, and the other end is hinged to the pusher table and can slide relative to the pusher table.

[0021] Furthermore, the shaping module includes a base and at least one constraint component disposed on the base. The base is provided with a plurality of positioning holes adapted to the shaped tube at intervals. The constraint component is used to press the shaped tube into the positioning holes to eliminate the deformation of the shaped tube.

[0022] Furthermore, the constraint assembly includes a limiting member and a pressure rod. The limiting member is fixed on the base, and one end of the pressure rod is hinged to the base. The pressure rod can be engaged in the limiting member to limit the shape of the tube.

[0023] Furthermore, the limiting member includes a fixing part and a snap-fit ​​part. The fixing part is fixed on the base, and the snap-fit ​​part has a limiting groove for the pressure rod to snap into.

[0024] Furthermore, the snap-fit ​​portion includes a support section and a guide section, the support section and the guide section forming an acute angle to form the limiting groove, and the guide section being arranged at an angle to guide the pressure rod.

[0026] In use, the shaped tubes are first placed into the tube handling device, which combs them into a radially upward-facing, queued arrangement and then exports them. The transfer module transfers the exported, combed shaped tubes to the shaping module located at the first set position. Then, the second conveying module conveys the shaping module from the first set position to the second set position. During the conveying process, the pressing module presses down on the deformed shaped tubes on the shaping module to eliminate the deformation.

As a result, the subsequent filling process is smoother and more convenient, and filling errors are less likely to occur. This can greatly improve production efficiency and product quality, and also help reduce labor costs and improve the level of automation. Attached Figure Description

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0043] The invention is described more specifically by way of example in the following paragraphs with reference to the accompanying drawings. The advantages and features of the invention will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the invention.

[0044] The following is in conjunction with the instruction manual appendix. Figures 4 to 8 The irregular tube conveying system of the present invention will be introduced.

[0045] In one embodiment, such as Figure 4 As shown, the irregular tube conveying system includes a tube body sorting device 41, a first conveying module, a transfer module, a pressing module 47, and a second conveying module.

[0046] The tube handling device 41 is used to comb the irregular tubes 101 into a radially upward, queued state and then export them.

[0047] The first conveying module includes a material conveyor belt and a plurality of shaping modules 31 arranged at intervals on the material conveyor belt. The shaping modules 31 are used to accommodate the shaped tubes 101, and the material conveyor belt is used to convey the shaping modules 31 to a first set position.

[0048] The transfer module is used to transfer the exported and combed irregular tube 101 to the shaping module 31 located at the first set position.

[0049] The pressing module 47 is used to press the deformed shaped tube 101 on the shaping module 31 to eliminate the deformation of the shaped tube 101.

[0050] The second conveying module is used to convey the shaping module 31 at the first set position to the second set position. At the second set position, another device will remove the shaped tube 101 from the shaping module 31.

[0051] In use, the shaped tube 101 is first placed into the tube body sorting device 41, which sorts the shaped tube 101 into a radially upward, queued state and then leads it out. The transfer module transfers the sorted shaped tube 101 to the shaping module 31 located at the first set position. Then, the second conveying module conveys the shaping module 31 from the first set position to the second set position. During the conveying process, the pressing module 47 presses the deformed shaped tube 101 on the shaping module 31 to eliminate the deformation of the shaped tube 101. The deformation of the shaped tube 101 is corrected, so that the openings of each small tube are restored to the same horizontal plane. As a result, the subsequent filling process is smoother and more convenient, and filling errors are less likely to occur. This can greatly improve production efficiency and product quality, and also help reduce labor costs and improve the level of automation.

[0052] In one embodiment, the tube handling device 41 includes a centrifugal drum and a drive unit for driving the centrifugal drum to rotate. The centrifugal drum has a receiving cavity for accommodating the shaped tube 101. A spiral conveying groove is provided on the inner side wall of the centrifugal drum. The spiral groove communicates with the discharge port on the outer side wall of the centrifugal drum for the shaped tube 101 to be discharged.

[0053] Specifically, the outer wall of the centrifugal drum is provided with a tube discharge trough 42 that communicates with the spiral conveying trough. The tube discharge trough 42 is arranged inclined from the discharge port toward the tube queue track 43. The end of the tube discharge trough 42 constitutes the discharge port. The driving component can be a drive motor, which can drive the centrifugal drum. Under the action of centrifugal force, the irregular tubes 101 inside the centrifugal drum gradually change to a radially upward and queued state and enter the spiral conveying trough, and finally exit from the discharge port.

[0054] In one embodiment, such as Figure 4As shown, the transfer module includes a tube body queue track 43 and a clamping assembly. The tube body queue track 43 is located below the tube body outlet to receive the shaped tube 101. The clamping assembly is used to clamp the shaped tube 101 on the tube body queue track 43 onto the shaping module 31 at the first set position. Specifically, after the shaped tube 101 enters the tube body outlet trough 42, it is guided to the tube body queue track 43. The clamping assembly includes a tube body gripper 44 and an actuator 45. The tube body gripper 44, driven by the actuator 45, clamps the shaped tube 101 and places it on the shaping module 31 located at the first set position.

[0055] In one embodiment, such as Figure 5 and Figure 6 As shown, the second conveying module includes a base 21, a platform, a pusher platform 33, a traction device 35, and a tilting device 37. The platform is fixedly connected to the base 21 and is used to support the shaping modules 31. The pusher platform 33 is located above the platform and is used to periodically push multiple shaping modules 31 forward. The traction device 35 is used to push the pusher platform 33 forward or backward periodically to convey the shaping modules 31. The tilting device 37 is used to rotate the pusher platform 33 before it moves backward so as to avoid the shaping modules 31 during the backward movement.

[0056] Specifically, the traction device 35 can push the pusher platform 33 forward or backward periodically. When moving forward, the pusher platform 33 can move the shaping module 31 on the platform a set distance. After each set distance, the flipping device 37 drives the pusher platform 33 to rotate to avoid the material. Then, the traction device 35 drives the pusher platform 33 to move backward. During this process, because the pusher platform 33 rotates, it will not interfere with the shaping module 31 during the backward movement. After moving to the correct position, the flipping device 37 drives the pusher platform 33 to rotate in the opposite direction to reset it. Since the space occupied by the pusher platform 33 after rotation is small, it is not necessary to reserve too much space for the pusher platform 33 after rotation. This reduces the installation space required for the material transfer device on the production line, which is beneficial for the miniaturization of the material transfer device on the production line.

[0057] Furthermore, in one embodiment, the platform may be a fixed mesh belt 39, which is fixedly connected to the base 21 via a mounting plate 3101 and a fixing seat 3100.

[0058] Furthermore, in one embodiment, the pusher platform 33 is provided with a plurality of equally spaced slots 331, the slots 331 being used to accommodate the shaping module 31 so as to push the shaping module 31 through the slot wall of the slot 331.

[0059] The width of the slot 331 is slightly larger than the width of the shaping module 31 to accommodate the shaping module 31.

[0060] Preferably, to prevent the pusher platform 33 from interfering with the shaping module 31 during its return process, the forward and backward distances of the pusher platform 33 are equal to the moving distance of the shaping module 31 plus half the difference in width between the slot 331 and the shaping module 31. In the initial state, the shaping module 31 is located in the middle of the slot 331. For example, assuming the width of the slot 331 is 53m, the width of the shaping module 31 is 4.53m, and the set distance for the shaping module 31 to move in each cycle is 83m, then the forward and backward distances of the pusher platform 33 are both 8 + (5 - 4.5) ÷ 2 = 8.253m.

[0061] Since there are a large number of slots 331, the distance that all shaping modules 31 move in each cycle is fixed. Each shaping module 31 will be gradually moved to the last slot 331 of the pusher table 33 and pushed off the pusher table 33 in the next cycle. During the transfer process, the distance between two adjacent shaping modules 31 is fixed.

[0062] In one embodiment, a slide rail 38 is provided on the base 21, the pusher platform 33 is rotatably connected to the slide rail 38 and can slide along the guide of the slide rail 38, and the output end of the traction device 35 is connected to the pusher platform 33 to push the pusher platform 33 to periodically move forward or backward.

[0063] Preferably, the slide rail 38 is fixed to the base 21 by a fixing plate 3103 and a mounting base 3102.

[0064] Furthermore, the slide rail 38 includes a frame and a rotating shaft mounted on the frame. The pusher 33 is hinged to the rotating shaft and can slide along the rotating shaft, so that the pusher 33 can periodically move forward or backward under the push of the pusher. The flipping device 37 can push the pusher 33 to rotate around the rotating shaft, so that the pusher 33 can avoid the shaping module 31 by flipping.

[0065] Preferably, the traction device 35 includes a traction device base 351 and a first push rod on the traction device base 351. The first push rod is an electric push rod, which is convenient to control and has good stability. In other embodiments, the first push rod can also be a pneumatic push rod.

[0066] In one embodiment, the flipping device 37 is a second push rod, one end of which is hinged to the base 21 and the other end of which is hinged to the push platform 33. In order to be restricted by the second push rod when the push platform 33 moves forward or backward, the other end of the second push rod can also slide relative to the push platform 33. Specifically, the push platform 33 is provided with a hinge shaft extending along the forward direction of the push platform 33. The length of the hinge shaft is greater than the forward or backward stroke of the push platform 33. When the push platform 33 moves forward or backward, the other end of the second push rod can slide relative to the hinge shaft.

[0067] In this embodiment, the second push rod is an electric push rod. In other embodiments, the second push rod can also be a pneumatic push rod. In other embodiments, the flipping device 37 can also be a swing motor, and the push platform 33 is connected to the output shaft of the swing motor, so that the swing motor drives the push platform 33 to flip.

[0068] In one embodiment, the material conveyor belt is used to transport the shaping module 31 to a set position on the platform, the set position being the position corresponding to the first slot 331 of the pusher platform 33. Preferably, the material conveyor belt is a conveyor mesh belt 36. In use, the shaping module 31 is transported by the material conveyor belt to the first slot 331 of the pusher platform 33, and then the pusher platform 33 transfers the shaping module 31 forward. Each time the pusher platform 33 advances, it flips and retracts once, and then flips back to its original position, so that the first slot 331 can accommodate the new shaping module 31 being transported.

[0069] In one embodiment, the material transfer device on the production line further includes a sensing device 32. The end of the material conveyor belt is adjacent to the designated position, and the sensing device 32 is positioned corresponding to the end of the conveyor belt to detect whether the shaping module 31 is in place. If it is not in place, it prompts the timely replenishment of the shaping module 31. Preferably, the sensing device 32 is an infrared sensor.

[0070] In one embodiment, the pressing module 47 includes a longitudinal electric push rod and a pressing member. The longitudinal electric push rod is disposed on the side of the platform, and the pressing member is disposed at the output end of the longitudinal electric push rod. Under the push of the longitudinal electric push rod, the pressing member can press the shaping module 31 to correct the deformation of the shaped tube 101.

[0071] In one embodiment, in order to improve the pressing accuracy of the pressing module 47, a tube positioning device 46 is also provided on the side of the platform. The tube positioning device 46 is equipped with an infrared sensor to monitor the position of the shaping module 31 in real time. When the shaping module 31 is detected to have reached the set position, the pressing module 47 is activated to press.

[0072] In one embodiment, such as Figure 7 As shown, the shaping module 31 includes a base 311 and at least one constraint component disposed on the base 311. The base 311 is provided with a plurality of positioning holes 312 adapted to the shaped tube 101 at intervals. The constraint component is used to press the shaped tube 101 into the positioning holes 312 to eliminate the deformation of the shaped tube 101.

[0073] As each of the small tubes of the shaped tube 101 is pressed into the positioning hole 312, the deformation of the shaped tube 101 is corrected under the pressing action of the constraint component, so that the openings of each small tube are restored to the same horizontal plane. As a result, the subsequent filling process is smoother and more convenient, and it is less likely to cause filling errors. This can greatly improve production efficiency and product quality, and also help reduce labor costs and improve the level of automation.

[0074] Preferably, the number of positioning holes 312 can be determined according to the number of small tubes in the shaped tube 101. For example, if the shaped tube 101 is an eight-unit tube, the number of positioning holes 312 can be eight; if the shaped tube 101 is a six-unit tube, the number of positioning holes 312 can be six. Of course, it is also possible to use a number of positioning holes 312 greater than the number of small tubes in the shaped tube 101.

[0075] The number of constraint components can be one or more. When the number of individual tubes in the irregular tube 101 is small, a smaller number of constraint components can be set, such as one or two. When the number of individual tubes in the irregular tube 101 is large, the number of constraint components can be increased appropriately. Preferably, in order to constrain the irregular tube 101 more stably, multiple constraint components are arranged at equal intervals.

[0076] In order to better constrain the irregular tube 101, the diameter of the positioning hole 312 is slightly larger than the outer diameter of each small tube in the irregular tube 101.

[0077] In one embodiment, the constraint assembly includes a limiting member 315 and a pressure rod 314. The limiting member 315 is fixed to the base 311, and one end of the pressure rod 314 is hinged to the base 311. The pressure rod 314 can be engaged in the limiting member 315 so that the pressure rod 314 limits the shape tube 101, thereby eliminating the deformation of the shape tube 101.

[0078] Furthermore, in one embodiment, such as Figure 8 As shown, the limiting member 315 includes a fixing part 3151 and a snap-fit ​​part. The fixing part 3151 is fixed to the base 311. For example, the fixing part 3151 can be fixed to the base 311 by welding. In other embodiments, the fixing part 3151 can also be fixed to the base 311 by a threaded connector.

[0079] Preferably, the snap-fit ​​part has a limiting groove 3154 for the pressure rod 314 to snap into. After the pressure rod 314 is pressed into the limiting groove 3154, it can press the shaped tube 101, thereby eliminating the deformation of the shaped tube 101 and restoring the openings of each small tube to the same horizontal plane. As a result, the subsequent filling process is smoother and more convenient, and filling errors are less likely to occur.

[0080] Specifically, the engaging portion includes a support section 3152 and a guide section 3153. The support section 3152 and the guide section 3153 form an acute angle to create the limiting groove 3154. The guide section 3153 is arranged at an angle to guide the pressure rod 314. The engaging portion can be made of a flexible metal sheet. The pressure rod 314 can slide along the inclined outer surface of the guide section 3153. During sliding, the guide section 3153 is compressed and moves towards the support end. After the pressure rod 314 passes the guide section 3153, the guide section 3153 returns to its original position. At this point, the pressure rod 314 enters the limiting groove 3154 and is constrained.

[0081] Furthermore, to accommodate the space occupied by the limiting member 315, the supporting segment 3152 and the fixing part 3151 form a right angle. Of course, in other embodiments, the angle between the supporting segment 3152 and the fixing part 3151 can also be an obtuse angle.

[0082] Furthermore, the constraint assembly also includes a reset member disposed on the base 311, the reset member being used to reset the pressure rod 314. Preferably, the reset member is a reset torsion spring 313.

[0083] In use, when the pressure rod 314 is pressed, it swings towards the locking part, causing the return torsion spring 313 to elastically deform. When the pressure rod 314 is removed from the locking groove 3154 of the locking part by the pressing module 47, the elastic potential energy in the return torsion spring 313 is released, causing the pressure rod 314 to return to its original position. It should be noted that after the shaping module 31 is transported to its destination, the pressure rod 314 is removed from the locking groove 3154 by another mechanism, which will not be described further in this invention.

[0084] In one embodiment, the base 311 is a cuboid block, and a plurality of positioning holes 312 are arranged sequentially at intervals along the length of the base 311, thereby making more reasonable use of the space of the base 311 and reducing the overall volume of the shaping module 31.

[0085] In one embodiment, after the pressure rod 314 is engaged with the limiting member 315, its extension direction is perpendicular to the arrangement direction of the plurality of positioning holes 312. This arrangement can reduce the contact area between the pressure rod 314 and the shaped tube 101, thereby avoiding contamination of the shaped tube 101 and ensuring the quality and safety of the shaped tube 101.

[0086] Furthermore, after the pressure rod 314 is engaged with the limiting member 315, the projection of the pressure rod 314 on the base 311 is located in the gap between two adjacent positioning holes 312. When the shaped tube 101 is located on the base 311, the pressure rod 314 will press on the connection position between two adjacent small tubes of the shaped tube 101, so that the shaped tube 101 will not interfere with the subsequent operation process.

[0087] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
