Abstract
Description
Technical Field
[0001] The utility model mainly relates to the field of material sample collection and processing equipment, in particular to a transceiver device used for pneumatic transportation. Background Art
[0002] In the sampling, sample preparation and testing of material (such as ore and coal), the prepared samples need to be transported from the workstation (laboratory) of this link to the workstation (laboratory) of the next link for the next stage of work. In the process of sample transportation, the quality accuracy control and transportation speed of the samples are particularly important. In the existing sample transportation work, some pneumatic pipeline transportation is used, which requires the establishment of a transceiver workstation at one end of the pneumatic transmission pipeline. Some practitioners have designed a transceiver for pneumatic conveying, which consists of a sealed door, a buffer pipe and a bottle pusher assembly. The buffer pipe is connected to the pneumatic conveying system. When the sample bottle enters the buffer pipe through the pneumatic conveying system, the airflow will push the sample bottle forward until it is close to the sealed door. When the detection proximity switch senses the sample bottle, the pneumatic conveying system stops outputting power, the bottle pusher cylinder starts, and the pusher head of the bottle pusher assembly pushes the sample bottle close to the sealed door. A card reader is provided on the sealed door, which can identify the detailed information of the sample bottle and write it into the database of the automatic storage and inspection cabinet. After the card reading is completed, the bottle pusher cylinder is retracted, and then the sealed door is opened, and the manipulator of the automatic storage and inspection cabinet moves to the docking position of the buffer pipe, and then the pusher head of the bottle pusher assembly is pushed out again, contacts the sample bottle and pushes it from the buffer pipe into the manipulator of the storage and inspection cabinet to collect the sample bottle. However, the above device still has the following defects:
[0003] In the device, the bottle pusher assembly is located at the rear end of the buffer pipe, and can extend into the buffer pipe at a preset angle under the drive of the cylinder. This design ensures that the bottle pusher assembly will not hinder the conveying process of the sample bottle in the buffer pipe when it retracts to the extreme position. However, this structural layout makes the moving trajectory of the pusher head occupy half of the layout space of the transceiver, and limits the transceiver to receiving only one sample bottle at a time. When there are two sample bottles in the buffer pipe, or the sample bottle is in the pusher head extended position, the pusher head of the bottle pusher assembly may get stuck with the sample bottle, causing equipment failure, and this failure state cannot be automatically restored.
[0004] Since the automatic storage and inspection cabinet and the pneumatic conveying system are two independent systems, they not only support automatic operation, but also allow manual intervention. In some cases, the sample bottle in the buffer pipe may not be correctly sensed by the detection sensor, causing the system to mistakenly judge that there is no sample bottle in the buffer pipe, thereby executing the second bottle sending action. In this case, multiple sample bottles may coexist in the sending and receiving device, which will cause the bottle pusher assembly to get stuck and cause failure. Utility Model Content

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0028] Embodiment 1
[0029] like Figures 1 to 5 As shown, the present embodiment discloses a transceiver device for pneumatic transport, including a buffer pipe 1, a port at one end of the buffer pipe 1 is used to communicate with the main pipe of the pneumatic transmission system, and a port at the other end of the buffer pipe 1 is provided with a sealing door assembly 2, and the sealing door assembly 2 is used to open and close the buffer pipe 1, and also includes a bottle pushing mechanism 3, the bottle pushing mechanism 3 includes at least a push hook assembly 31 and a drive assembly 32, the push hook assembly 31 is arranged under the buffer pipe 1, and is used to push the sample bottle forward, and a slot for the push hook assembly 31 to enter and exit is provided at the bottom of the buffer pipe 1, and the drive assembly 32 is used to drive the push hook assembly 31 to extend into or withdraw from the buffer pipe 1 from the slot and drive the push hook assembly 31 to reciprocate in the buffer pipe 1.
[0030] When the driving component 32 is in the initial state, the push hook component 31 is located below the buffer pipe 1 and does not enter the buffer pipe 1, thereby not causing any obstruction to the movement of the sample bottle in the buffer pipe 1; when it is detected that the sample bottle enters the buffer pipe 1, the driving component 32 drives the push hook component 31 to move, so that the push hook component 31 extends into the buffer pipe 1 and moves forward under the drive of the driving component 32, thereby pushing the sample bottle forward and realizing the collection of the sample bottle; the transceiver for pneumatic transportation in this embodiment combines the stroke of the driving component 32 with the sample bottle storage area in the buffer pipe 1, thereby realizing efficient use of space. On the premise of keeping the overall layout space of the transceiver unchanged, more storage space is provided for the sample bottle, which greatly reduces the failure rate of the equipment.
[0031] In this embodiment, the bottle pushing mechanism 3 also includes a base 33 and a slide rail 34. The push hook assembly 31 is installed on the base 33, and the base 33 is connected to the slide rail 34; the push hook assembly 31 includes a push hook 311, a torsion spring 312 and a stop pin 313. The push hook 311 is connected to the torsion spring 312, and the stop pin 313 is used to resist the push hook 311 when the push hook 311 is in the initial position; the driving assembly 32 is a cylinder 321, and the cylinder 321 is used to drive the base 33 to move on the slide rail 34.
[0032] When the cylinder 321 is in the initial state, the stop pin 313 will effectively resist the push hook 311, causing it to rotate in the clockwise direction. At this time, the push hook 311 is located below the buffer pipe 1 and does not enter the buffer pipe 1, thereby ensuring that there is no obstruction to the movement of the sample bottle in the buffer pipe 1. When it is detected that the sample bottle enters the buffer pipe 1, the cylinder 321 drives the push hook 311 to move, and the push hook 311 gradually disengages from the stop pin 313, and rotates in the counterclockwise direction under the reverse rotation force of the torsion spring 312. This process will continue until the push hook 311 contacts the limit structure on the base 33. At this time, the push hook 311 will extend into the buffer pipe 1 to push the sample bottle forward, and it is not easy for the push hook 311 to get stuck with the sample bottle. This structural design can operate normally even if three sample bottles are stacked in the buffer pipe 1, greatly improving the fault tolerance of the device.
[0033] In this embodiment, an inspection ash box 4 is further provided below the buffer pipe 1. The inspection ash box 4 can collect dust and debris inside the buffer pipe 1.
[0034] In this embodiment, a first detection component 5 is provided on the buffer pipe 1 to detect whether there is a sample bottle at the initial position where the bottle pushing mechanism 3 enters and exits the buffer pipe 1. When the first detection component 5 detects that there is a sample bottle at the position where the push hook 311 extends into the buffer pipe 1, the first detection component 5 sends an alarm signal to the system to prompt the staff to intervene, thereby improving the user experience of the equipment and greatly improving the reliability of the equipment.
[0035] In this embodiment, a second detection component 6 is provided on the buffer pipe 1 near the sealing door component 2 to detect whether a sample bottle moves to the sealing door component 2. When it is detected that a sample bottle contacts the sealing door component 2, an external manipulator is called to open the door for sampling.
[0036] In this embodiment, a one-way exhaust valve 7 is provided on the buffer pipe 1, so that the positive pressure driving gas can be discharged from the one-way exhaust valve 7 to the outside of the buffer pipe 1 after the sample bottle passes through. Since the positive pressure driving gas that originally drives the sample bottle to be transported will be discharged from the buffer pipe 1 through the one-way exhaust valve 7, the driving force on the sample bottle is instantly reduced or even lost, so that a buffer is formed for the sample bottle.
[0037] In this embodiment, a buffer is provided on the sealing door assembly 2, and the buffer is used to buffer the impact force of the sample bottle transmitted. The buffer can be any component with elastic compression, such as a spring or a silicone pad, a rubber pad, etc.
[0038] In this embodiment, a frame 8 is also included, and the buffer pipe 1 and the bottle pushing mechanism 3 are installed on the frame 8.
[0039] Working principle: When the sample bottle enters the buffer pipe 1 through the pneumatic conveying system, the airflow will push the sample bottle forward. The first detection component 5 detects whether there is a sample bottle at the initial position of the bottle pushing mechanism 3 entering and exiting the buffer pipe 1. When the detection result is that there is no sample bottle, the cylinder 321 drives the push hook 311 to move, and the push hook 311 gradually disengages from the stop pin 313 and rotates in the counterclockwise direction under the reverse rotation force of the torsion spring 312. This process will continue until the push hook 311 contacts the limit structure on the base 33, and the push hook 311 will extend into the buffer pipe 1. When the second detection component 6 detects the sample bottle, the cylinder 321 drives the push hook 311 to move forward, pushing the sample bottle forward and close to the sealing door component 2. A card reading device is provided on the sealing door component 2, which can identify the detailed information of the sample bottle and write it into the database of the automatic storage and inspection cabinet. After the card reading is completed, the cylinder 321 is retracted, and then the sealing door component 2 is opened, and the manipulator of the automatic storage and inspection cabinet moves to the docking position of the buffer pipe 1, and then the push hook 311 of the bottle pushing mechanism 3 moves forward again, and pushes the sample bottle from the buffer pipe 1 into the manipulator of the storage and inspection cabinet to realize the collection of the sample bottle.
[0040] Embodiment 2
[0041] like Figure 6 As shown, this embodiment is basically the same as the first embodiment, except that, in this embodiment, the push hook assembly 31 includes a push hook 311, the driving assembly 32 includes a cylinder 321 and a lifting assembly 322, the push hook 311 is installed on the base 33 through the lifting assembly 322, the lifting assembly 322 is used to drive the push hook 311 to move up and down in and out of the buffer pipe 1, and the cylinder 321 is used to drive the base 33 to move on the slide rail 34.
[0042] Working principle: When the sample bottle enters the buffer pipe 1 through the pneumatic conveying system, the airflow will push the sample bottle forward. The first detection component 5 detects whether there is a sample bottle at the initial position of the bottle pushing mechanism 3 entering and exiting the buffer pipe 1. When the detection result is that there is no sample bottle, the lifting component 322 drives the push hook 311 to move upward and enter the buffer pipe 1, and then the cylinder 321 drives the push hook 311 to move forward, pushing the sample bottle forward and close to the sealing door component 2. A card reading device is provided on the sealing door component 2, which can identify the detailed information of the sample bottle and write it into the database of the automatic storage and inspection cabinet. After the card reading is completed, the cylinder 321 is retracted, and then the sealing door component 2 is opened, and the manipulator of the automatic storage and inspection cabinet moves to the docking position of the buffer pipe 1, and then the push hook 311 of the bottle pushing mechanism 3 moves forward again, contacts the sample bottle and pushes it from the buffer pipe 1 into the manipulator of the storage and inspection cabinet to realize the collection of the sample bottle.

All technical solutions under the idea of the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should be regarded as the protection scope of the utility model.
