Description

Technical Field

[0001] This application relates to the field of chemical production equipment, and in particular to an automated sample transfer device for chemical production. Background Technology

[0002] In chemical production processes, it is often necessary to test samples of finished or semi-finished products produced in certain steps. If, due to objective factors, the production station and the testing station are far apart, the samples are usually packaged first and then transported to the testing point for testing. This transportation process involves manual carrying, resulting in high labor and time costs and wasted resources. Summary of the Invention

[0003] To address the aforementioned issues, this application provides an automated sample transfer device for chemical production.

[0004] The automated sample transfer device for chemical production provided in this application adopts the following technical solution:

[0005] An automated sample transfer device for chemical production includes a transfer frame with a transfer body wound around it. A swing tube for holding samples is connected to the transfer body. One end along the direction of the transfer body is the starting point, and the other end is the unloading point. The transfer frame is equipped with a drive source for controlling the operation of the transfer body.

[0006] By adopting the above technical solution, under the action of the driving source, the shuttle tube carrying the sample moves from the starting point to the unloading point with the conveyor. The transportation process is unmanned and automated. At the same time, the air-transfer of the shuttle tube has a strong adaptability to complex transportation environments, which can significantly improve the overall economy of sample testing.

[0007] Preferably, the lower end of the transfer cylinder is provided with a discharge hole, and a sealing cover is movably connected to the transfer cylinder. The sealing cover is used to control the closing or opening of the discharge hole. A receiving bucket is provided on the conveyor frame at the discharge point, and the receiving bucket is located below the conveyor body.

[0008] By adopting the above technical solution, when the discharge hole is closed, the sample can be stably stored in the transfer tube. When the sealing cover is moved, the discharge hole is opened, and the sample in the transfer tube can fall out of the transfer tube.

[0009] Preferably, a control rod is hinged to the transfer cylinder, the control rod is fixedly connected to the sealing cover, and a sealing magnet is connected to the transfer cylinder. The sealing magnet attracts the control rod, and when the sealing magnet abuts against the control rod, the sealing cover closes the discharge hole.

[0010] By adopting the above technical solution, under natural conditions, the attraction of the sealing magnet to the control rod allows the control rod to remain stable relative to the swing cylinder, so that the sealing cover can continuously seal the unloading hole.

[0011] Preferably, an opening assembly is provided at the unloading point. The opening assembly includes a lever, which is located on the side of the receiving bucket near the starting point. The rotation axis of the control rod is horizontal and perpendicular to the movement direction of the transfer cylinder. During the movement of the transfer cylinder past the receiving bucket, the control rod is located on the side of the transfer cylinder facing the starting point, and the hinge axis of the control rod is located at the upper end of the control rod. When the control rod abuts against the sealing magnet, the lower end of the control rod is lower than the transfer cylinder, and the lever abuts against the side of the control rod away from the starting point.

[0012] By adopting the above technical solution, when the transfer cylinder passes the actuating rod, the actuating rod and the control rod abut against each other and have a relative motion tendency. The actuating rod pushes the control rod to swing relative to the transfer cylinder, thereby achieving the purpose of making the sealing cover move relative to the transfer cylinder to open the unloading hole.

[0013] Preferably, the conveyor is a conveyor rope, and a plurality of guide wheels are rotatably connected to the conveyor frame. The conveyor rope passes around each guide wheel in sequence. A suspension body is connected between the conveyor rope and the transfer cylinder. The suspension body is a flexible material. Two guide plates are provided on the conveyor frame at the unloading point. A receiving channel for the transfer cylinder to pass through is formed between the two guide plates. The distance between the two guide plates gradually decreases along the direction of movement of the transfer cylinder. The actuating rod is located on the side of the guide plate away from the starting point.

[0014] By adopting the above technical solution, the guide plate is used to guide and straighten the incoming shuttle tube, improve the stability of the state when the control lever and the toggle lever are in contact, so that the control lever can be opened smoothly.

[0015] Preferably, the two guide plates are fixedly connected to each other and hinged to the conveyor frame. The hinge axis of the guide plate is parallel to the hinge axis of the control rod. The actuating rod is fixedly connected to the guide plate. The lower edge of the guide plate is fixedly connected to the side facing the receiving channel with an abutment slope plate. The length direction of the abutment slope plate is consistent with the length direction of the guide plate. In the natural state, the end of the abutment slope plate away from the starting point is higher than the end near the starting point, and the actuating rod is higher than the abutment slope plate. Both abutment slope plates abut against the ferry tube. The lower end of the control rod is fixedly connected to a bent part, which is inclined relative to the control rod towards the side away from the starting point.

[0016] By adopting the above technical solution, as the swing cylinder continues to move, the thrust from the swing cylinder to the abutting slope increases, causing it to rotate. Its shape changes so that the end near the receiving bucket is lowered to a height below the hinge shaft. During this process, the swing cylinder remains in the receiving channel and remains in contact with the abutting slope until the bent part of the control rod contacts the actuating rod. At this point, the swing cylinder disengages from the abutting slope, the pressure on the abutting slope decreases, and it tends to rotate and reset. At this time, the actuating rod pushes the control rod backward and upward, and the raised swing cylinder begins to swing downward. Driven by inertia, the control rod separates from the sealing magnet, and the unloading hole has a large opening range, which is conducive to the smooth falling of the sample inside.

[0017] Preferably, the conveyor frame has a limiting hole, and a limiting rope is fixedly connected to the guide plate or the abutment slope plate. The other end of the limiting rope passes through the limiting hole and is fixedly connected to a limiting body. The width of the limiting body is greater than the diameter of the limiting hole.

[0018] By adopting the above technical solution, during the rotation of the abutment slope plate, the limiting rope shuttles through the limiting hole. When the limiting body abuts the conveyor frame, the abutment slope plate is in the maximum rotation amplitude state and cannot continue to rotate. Thus, the limiting rope controls the rotation amplitude of the abutment slope plate during the working process.

[0019] Preferably, the suspension body is a suspension chain, which includes several joint units, with adjacent joint units hinged to each other, and the axis of the hinge axis being parallel to the length direction of the transmission rope.

[0020] By adopting the above technical solution, the swing cylinder has a high degree of freedom in left and right swinging during the transmission process, but a low degree of freedom in front and back swinging. This is conducive to the swing cylinder and the suspended body changing their shape naturally when passing the guide wheel, thereby improving the smoothness of the swing cylinder and the suspended body during operation.

[0021] Preferably, the guide wheel is located on one side of the conveyor frame, and a transition guide is fixedly connected to the conveyor frame at the guide wheel. The transition guide is located below the guide wheel, with its middle part located on the side of the guide wheel away from the conveyor frame and its two ends located on the side of the guide wheel close to the conveyor frame.

[0022] By adopting the above technical solution, when the suspension body and the swing cylinder move to the guide wheel, the transition guide body can smoothly move the swing cylinder laterally, and the suspension body bends and deforms laterally, thereby reducing the direct contact between the swing cylinder and the suspension body and the guide wheel surface, and playing a role in structural protection for each component.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. With the setting of the conveyor frame and the conveyor body, under the action of the drive source, the shuttle tube carrying the sample moves from the starting point to the unloading point with the conveyor body. The transportation process is unmanned and automated. At the same time, the air-transfer of the shuttle tube has a strong adaptability to complex transportation environments, which can significantly improve the overall economy of sample testing.

[0025] 2. With the setting of the opening component, when the transfer cylinder runs to the receiving bucket at the unloading point, the unloading hole can be opened by the opening component, and the sample placed inside will naturally fall into the receiving bucket, thus completing the sample transportation.

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses an automated sample transfer device for chemical production, such as... Figure 1As shown, the system includes a conveyor frame 1 and a conveyor body 16. A transfer tube 2 is connected to the conveyor body 16. The conveyor body 16 circulates around the conveyor frame 1. One end of the conveyor body 16 along its circulation direction is the starting point 14, and the other end is the unloading point 15. The transfer tube 2 is connected to the conveyor body 16. The operator puts the sample to be tested into the transfer tube 2 at the starting point 14, and the conveyor body 16 carries the transfer tube 2 from the starting point 14 to the unloading point 15.

[0034] like Figure 1 and 2 As shown, the conveyor body 16 is a conveyor rope. Several guide wheels 11 are rotatably mounted on the conveyor frame 1 along the direction of the conveyor rope's travel. The conveyor frame 1 is equipped with a drive source 17 for controlling the operation of the conveyor body 16. The drive source 17 is a motor, and its output shaft is coaxially and fixedly connected to the guide wheel 11 closest to the unloading point 15. The motor controls the rotation of the guide wheel 11 to provide power for the movement of the conveyor rope. A suspension body 25 is provided between the conveyor rope and the swing cylinder 2. The suspension body 25 is a deformable flexible material used for suspending the swing cylinder 2 on the conveyor rope. The suspension body 25 is a suspension chain, which includes several joint units 251. Adjacent joint units 251 are hinged together, and the axis of the hinge is parallel to the length direction of the conveyor rope. This means that during the conveying process, the swing cylinder 2 has a high degree of freedom in left-right swinging but a low degree of freedom in forward-backward swinging. The top end of the suspension chain is fitted onto the conveyor rope, and the bottom end is fixedly connected to the side wall of the swing cylinder 2.

[0035] like Figure 1 As shown, some guide wheels 11 have their axes vertically aligned for lateral guidance of the conveyor rope, while others have their axes horizontally aligned for longitudinal guidance. All guide wheels 11 are located on the same side of the conveyor frame 1. A transition guide 12 is fixedly connected to the conveyor frame 1 at each guide wheel 11. The transition guide 12 is located below the guide wheels 11, with its middle portion on the side of the guide wheel 11 away from the conveyor frame 1 and its two ends on the side of the guide wheel 11 closer to the conveyor frame 1. When the suspension body 25 and the swing cylinder 2 move to the guide wheel 11, the transition guide 12 can smoothly move the swing cylinder 2 laterally, causing the suspension body 25 to bend laterally. This reduces the direct contact between the swing cylinder 2, the suspension body 25, and the guide wheel 11 surface, providing structural protection for each component.

[0036] like Figure 1 and 2As shown, the axes of the two guide wheels 11 at the far end of the conveying direction are horizontal. The lower conveyor rope moves from the starting point 14 to the unloading point 15, while the upper conveyor rope moves in the opposite direction. An unloading hole 21 is provided at the lower end of the transfer cylinder 2. A sealing cover 22 is movably connected to the transfer cylinder 2, controlling the opening or closing of the unloading hole 21. A control rod 23 is hinged to the transfer cylinder 2 and fixedly connected to the sealing cover 22. A sealing magnet 24 is connected to the transfer cylinder 2, attracting the control rod 23. When the sealing magnet 24 abuts against the control rod 23, the sealing cover 22 closes the unloading hole 21. The suspension body 25 is located on one side of the transfer cylinder 2 along its travel direction, and the control rod 23 is located on the side of the transfer cylinder 2 away from its own travel direction. The hinge axis of the control rod 23 is horizontal and perpendicular to the travel direction of the transfer cylinder 2. In its natural state, the control rod 23 abuts against the sealing magnet 24. At this time, the length direction of the control rod 23 is parallel to the axis of the swing tube 2. The hinge axis of the control rod 23 is located at its upper end. The lower end of the control rod 23 is fixedly connected to a bending part 231. The bending part 231 is inclined relative to the control rod 23 towards the side away from the starting point 14.

[0037] like Figure 1 and 3 As shown, a receiving bucket 151 and an opening assembly 3 are provided on the conveyor frame 1 at the unloading point 15. The receiving bucket 151 is located below the conveyor body 16. The opening assembly 3 is used to actuate the control lever 23 of the passing shuttle 2 to open the unloading hole 21. The opening assembly 3 includes an actuating rod 31 and a guide plate 32. Two guide plates 32 are provided, with their surfaces facing each other, forming a receiving channel 34 for the shuttle 2 to pass through. The distance between the two guide plates 32 gradually decreases along the direction of movement of the shuttle 2. The actuating rod 31 is fixedly connected to the side of the guide plate 32 away from the starting point 14. An abutment slope 33 is fixedly connected to the lower edge of the guide plate 32 facing the receiving channel 34. The length direction of the abutment slope 33 is consistent with the length direction of the guide plate 32. The receiving bucket 151 is located on the side of the abutment slope 33 away from the starting point 14, and the bucket opening is lower than the abutment slope 33.

[0038] like Figure 3 , 4As shown in Figure 5, the guide plate 32 is hinged to the conveyor frame 1, with the hinge axis horizontal and perpendicular to the moving direction of the transfer cylinder 2. In its natural state, the end of the abutment slope 33 furthest from the starting point 14 is higher than the end closest to the starting point 14, and the actuating rod 31 is higher than the abutment slope 33. When the transfer cylinder 2 enters the receiving channel 34, both abutment slopes 33 abut against the transfer cylinder 2. As the transfer cylinder 2 continues to move, the thrust from the transfer cylinder 2 on the abutment slope 33 increases, causing it to rotate. Its shape changes so that the end closest to the receiving bucket 151 is lowered to a height below the hinge axis. During this process, the transfer cylinder 2 remains in the receiving channel. The control rod 23 is in contact with the abutment slope 33 until the bent part 231 of the control rod 23 contacts the actuating rod 31. At this time, the swing cylinder 2 disengages from the abutment slope 33, and the pressure on the abutment slope 33 decreases, causing it to rotate and reset. At this time, the actuating rod 31 moves the control rod 23 backward and upward. Simultaneously, the raised swing cylinder 2 begins to swing downward. Driven by inertia, the control rod 23 separates from the sealing magnet 24, and the discharge hole 21 has a large opening range, which is conducive to the smooth falling of the sample inside.

[0039] like Figure 3 , 4 As shown in Figure 5, the conveyor frame 1 has a limiting hole 13. Both ends of the abutment slope plate 33 are fixedly connected to a limiting rope 35. The other end of the limiting rope 35 passes through the limiting hole 13 and is fixedly connected to a limiting body 351. The width of the limiting body 351 is larger than the diameter of the limiting hole 13. During the rotation of the abutment slope plate 33, the limiting rope 35 shuttles through the limiting hole 13. When the limiting body 351 abuts the conveyor frame 1, the abutment slope plate 33 is in the maximum rotation amplitude state and cannot continue to rotate. Thus, the limiting rope 35 controls the rotation amplitude of the abutment slope plate 33 during the working process.

[0040] The implementation principle of an automated sample transfer device for chemical production according to an embodiment of this application is as follows:

[0041] The operator places the sample in the transfer cylinder 2 at the starting point 14, and then the transfer cylinder 2 moves to the unloading point 15. When it reaches the receiving bucket 151, the control rod 23 swings under the action of the opening component 3, the unloading hole 21 is opened, and the sample inside falls into the receiving bucket 151. The sample is taken out by the staff at the unloading point 15. The transfer cylinder 2 continues to move back under the operation of the conveyor rope in order to carry out the next sample transportation operation.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
