Description

Technical Field

[0001] The present invention relates to the technical field of material sealing, and in particular to a sample separation and packaging system. Background Art

[0002] Current intelligent sampling and packaging systems are based on a disc-shaped structure. The disc rotates around a fixed axis and is equipped with multiple positions for positioning and installing material canisters. The system's controller selects the appropriate canister based on the type of material and controls the disc to rotate the canister to the system's feed port, thereby filling the designated material tube.

[0003] First, the intelligent sampling and packaging system requires manual assistance to load and unload material cans. For example, when one or more cans on the disc are full, they need to be manually removed and replaced with empty ones. Second, it lacks the ability to expand workstations. The disc has a fixed number of workstations, making it difficult to flexibly adjust to changes in the actual production process, resulting in poor adaptability.

[0004] In addition, the size of the disc determines the number of all workstations. In order to meet the demand for the number of workstations of the intelligent sampling and packaging system, the size of the disc is increased accordingly, which makes the intelligent sampling and packaging system huge.

[0019] Preferably, the main body module is provided with a first code reading and writing component for reading and writing work material information into the packaging barrel; the work material information includes work material quality and work material type;

[0020] It also includes a controller electrically connected to the main body module, the empty barrel access control component and the packaging barrel reversing device; when the packaging barrel is filled with the main body module, the controller closes the packaging barrel reversing device and opens the empty barrel access control component.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0039] Please refer to Figures 1 to 9 , Figure 1 This is a schematic structural diagram of a first sample separation and packaging system provided by an embodiment of the present invention; Figure 2 This is a structural diagram of a second sample separation and packaging system provided by an embodiment of the present invention; Figure 3 for Figure 2 Front view of Figure 4 for Figure 2 Left view of; Figure 5 A schematic structural diagram of a main module provided in an embodiment of the present invention; Figure 6 for Figure 5 Side view of; Figure 7 for Figure 5 A top view of Figure 8 This is a schematic structural diagram of a third sample separation and packaging system provided by an embodiment of the present invention; Figure 9 This is a structural diagram of the fourth sample separation and packaging system provided by an embodiment of the present invention.

[0040] The present invention provides a sampling and packaging system, comprising a main module 1 for filling and sealing a designated packaging barrel 01 with work materials according to the type of work materials, an empty barrel conveyor belt 2 and a full barrel conveyor belt 3 connected to both ends of a conveyor belt 11 inside the main module 1.

[0041] The conveyor belt 11 inside the main module 1 is used to place and drive multiple packaging barrels 01 to translate relative to the filling device of the main module 1, so that the main module 1 can fill the aforementioned multiple packaging barrels 01 with materials and seal them separately.

[0042] Conveyor belt 11 is used to transport packaging barrels 01 being filled. Therefore, the length of conveyor belt 11 determines the number of filling stations. Similarly, empty barrel conveyor belt 2 is used to transport empty packaging barrels 01. The loading station of packaging barrels 01 is determined by the length of empty barrel conveyor belt 2. Full barrel conveyor belt 3 is used to transport filled packaging barrels 01. The unloading station of packaging barrels 01 is determined by the length of full barrel conveyor belt 3.

[0043] The conveyor belt 11 can move in a single direction. For example, the filling device of the main module 1 fills the aforementioned multiple packaging barrels 01 one by one, then the packaging barrel 01 close to the full barrel conveyor belt 3 is filled first, and the packaging barrel 01 close to the empty barrel conveyor belt 2 is filled last. Therefore, the conveyor belt 11 moves in a single direction from the empty barrel conveyor belt 2 to the full barrel conveyor belt 3. The movement of the conveyor belt 11 can also be adjusted by the control unit of the main module 1 to achieve reciprocating movement. For example, the main module 1 identifies the type of work material and fills a specific type of work material into a designated packaging barrel 01 among the aforementioned multiple packaging barrels 01. When the types of work materials transported by the main module 1 twice are different, the control unit of the main module 1 controls the conveyor belt 11 to move back and forth to ensure that the work material transported in the latter time is filled into the corresponding packaging barrel 01.

[0044] The connection between the empty barrel conveyor belt 2 and the inlet end of conveyor belt 11 means that the outlet end of empty barrel conveyor belt 2 and the inlet end of conveyor belt 11 form a smooth transition. For example, if empty barrel conveyor belt 2 and conveyor belt 11 are both arranged horizontally, they are in the same horizontal plane. If empty barrel conveyor belt 2 and conveyor belt 11 are not in the same horizontal plane, the outlet end of empty barrel conveyor belt 2 and the inlet end of conveyor belt 11 are at the same height. When the empty packaging barrel 01 moves to the outlet end of empty barrel conveyor belt 2 along empty barrel conveyor belt 2, it is driven by the motor of empty barrel conveyor belt 2 and enters the inlet end of conveyor belt 11, realizing automatic loading of empty packaging barrel 01, thereby improving the automation of loading packaging barrel 01 of the sampling and packaging system.

[0045] The connection between the full-bucket conveyor belt 3 and the outlet of conveyor belt 11 creates a smooth transition between the inlet of full-bucket conveyor belt 3 and the outlet of conveyor belt 11. As the filled packaging bucket 01 moves along conveyor belt 11 to the outlet of conveyor belt 11, it is driven by the motor of conveyor belt 11 and enters the inlet of full-bucket conveyor belt 3, enabling automatic unloading of the filled packaging bucket 01. This improves the automation of unloading packaging buckets 01 in the sampling and packaging system.

[0046] In summary, the sampling and packaging system provided by the present invention realizes the filling of materials into multiple packaging barrels 01 through the main body module 1 having a conveyor belt 11, and realizes the loading and unloading of materials for the packaging barrels 01 into the main body module 1 in combination with the empty barrel conveyor belt 2 and the full barrel conveyor belt 3. The packaging barrels 01 are transported in the form of being stacked in sequence on the empty barrel conveyor belt 2 and the full barrel conveyor belt 3, and the station adjustment is realized in the form of being stacked in sequence on the conveyor belt 11. Therefore, the sampling and packaging system can expand the loading station, the filling station and the unloading station respectively by extending the empty barrel conveyor belt 2, the conveyor belt 11 and the full barrel conveyor belt 3. In particular, for the conveyor belt 11, extending the length of the conveyor belt 11 has no effect on the other structures of the main body module 1 except the conveyor belt 11 and its normal operation. Therefore, it can simplify the expansion of the filling station, reasonably and effectively utilize space, and flexibly arrange the layout to adapt to the specific sampling and packaging process line.

[0047] The sample separation and packaging system provided by the present invention will be further described below in conjunction with the accompanying drawings and implementation methods.

[0048] The main body module 1 provided by the present invention may include a conveyor belt 11 , a clamping and positioning assembly 12 disposed adjacent to the belt surface of the conveyor belt 11 , and a filling assembly and an opening cover assembly 14 disposed above the conveyor belt 11 .

[0049] The conveyor belt 11 is usually arranged horizontally, and the opening of any packaging barrel 01 placed on the surface of the conveyor belt 11 faces upward, so that the working material of the filling assembly can fall from the opening into the packaging barrel 01. The conveyor belt 11 can be driven by the main module motor 19 inside the main module 1.

[0050] The clamping and positioning assembly 12 is located adjacent to the conveyor belt 11 and is used to clamp and release the packaging barrel 01 currently being filled. After the clamping and positioning assembly 12 clamps the packaging barrel 01, the filling assembly and the opening and sealing assembly 14 are respectively moved to the upper part of the packaging barrel 01 to sequentially open the lid, fill the packaging barrel, and seal the barrel.

[0051] To facilitate the operation of the card loading and positioning assembly 12, the main module 1 may also be provided with a main module access control assembly 18. When the card loading and positioning assembly 12 is loading a specific packaging bucket 01 on the surface of the conveyor belt 11, the main module access control assembly opens, blocking the packaging bucket 01 and the packaging bucket 01 behind it. During this process, the conveyor belt 11 maintains normal operation; only the packaging bucket 01 is blocked by the main module access control assembly 18 and cannot move synchronously with the conveyor belt 11.

[0052] In this embodiment, the main module 1 may further include a slide rail 15 fixed parallel to the conveyor belt 11, and the material dropper 131 of the filling assembly and the unsealing cover assembly 14 are respectively slidably connected to the slide rail 15. When the clamping and positioning assembly 12 clamps the specified packaging barrel 01, first, the unsealing cover assembly 14 moves along the slide rail 15 to the top of the aforementioned packaging barrel 01 and removes the lid of the packaging barrel 01; second, the unsealing cover assembly 14 drives the aforementioned lid to move along the slide rail 15 and reset; then, the material dropper 131 of the filling assembly moves along the slide rail 15 to the top of the aforementioned packaging barrel 01 and fills the packaging barrel 01 with material. After filling, the material dropper 131 of the filling assembly moves along the slide rail 15 and resets; finally, the unsealing cover assembly 14 drives the aforementioned lid to move along the slide rail 15 again to the top of the packaging barrel 01, thereby sealing the lid to the packaging barrel 01.

[0053] The specific structure and function of the filling component are adapted to the production line layout of the sampling and packaging system. Figures 2 to 9 Taking the sample sorting and packaging system provided as an example, the work materials in this system are supplied by a separate work material transport line. Therefore, the filling assembly is solely responsible for dispensing the work materials from this transport line into the multiple packaging barrels 01 on the surface of conveyor belt 11. Based on this structural foundation, the filling assembly primarily serves to guide the work materials down the barrels. Of course, if the work materials in the sample sorting and packaging system are supplied by the filling assembly, the filling assembly will accordingly serve both as a storage material and as a guide for the work materials to fall into the packaging barrels 01.

[0054] The unsealing lid assembly 14 is used to open the lid of the packaging barrel 01 before the filling assembly fills the packaging barrel 01 on the surface of the conveyor belt 11, and is also used to close the lid of the packaging barrel 01 after the filling assembly has completed filling the packaging barrel 01. It can be seen that in this embodiment, each packaging barrel 01 is transported with a sealed lid, and the lid is only opened by the unsealing lid assembly 14 when filling. Therefore, the sampling and packaging system provided by this embodiment can reduce the water loss of the work materials in the packaging barrel 01 during transportation. Obviously, this is for work materials that are prone to water loss. When this sampling and packaging system is used to pack work materials that easily absorb water, it can reduce the amount of water absorbed by the work materials in the packaging barrel 01 during transportation.

[0055] A first photoelectric switch 17 may also be provided in the main module 1 for obtaining the position of the packaging barrel 01 on the surface of the conveyor belt 11 so that the card positioning assembly 12, the opening cover assembly 14 and the filling assembly can be operated in sequence.

[0056] Compared with the existing technology that requires providing a cover body separately to the material tank after filling, the sampling packaging system provided by the present invention realizes the simultaneous transportation of the cover body and the barrel body of the packaging barrel 01. Therefore, one packaging barrel 01 corresponds to one cover body, and there is no need to manually load the cover body.

[0057] The unsealing cover assembly 14 can adopt relevant structures in the existing technology, such as through negative pressure or electromagnetic adsorption of the cover body, thereby driving the cover body close to the barrel opening of the packaging barrel 01 to achieve sealing and driving the cover body away from the barrel opening of the packaging barrel 01 to open the packaging barrel 01.

[0058] Furthermore, the filling assembly includes a dropper 131 , a silo 133 and a weigher 132 .

[0059] The weigher 132 is connected to the silo 133 and is used to weigh the mass of the work material in the silo 133 .

[0060] The hopper 133 is located above the dropper 131 and is fixed directly above the positioning assembly 12. The entrance of the hopper 133 is located adjacent to the material transport line. In other words, the hopper 133 of this filling assembly serves only as a temporary storage for materials, which are then supplied by the material transport line. Because the material transport line is relatively fixed, only the dropper 131 is slidably connected to the slide rail 15 in this filling assembly. The hopper 133 and scale 132 are both fixedly mounted relative to the frame of the main module 1.

[0061] The unsealing cover assembly 14 used in the present invention may include a telescopic rod longitudinally connected to the slide rail 15 and an electromagnet adsorption head fixed to the bottom end of the telescopic rod for adsorbing the cover of the packaging barrel 01 when powered on.

[0062] The telescopic rod is longitudinally fixed to the first slider of the slide rail 15. As the first slider moves along the slide rail 15, the telescopic rod translates relative to the already mounted packaging bucket 01. When the telescopic rod moves above and aligns with the packaging bucket 01, it extends and retracts, moving the lid, attached to the bottom of the telescopic rod, closer to and farther from the packaging bucket 01. Correspondingly, the discharge port is fixed to the second slider of the slide rail 15, which drives the discharge port to translate relative to the already mounted packaging bucket 01.

[0063] The electromagnet adsorption head is connected to a power source. When the power is on, the bottom end of the telescopic rod generates magnetism to adsorb the cover; when the power is off, the magnetism at the bottom end of the telescopic rod disappears and the cover is separated from the bottom end of the telescopic rod.

[0064] This embodiment adopts the electromagnetic adsorption principle to realize the opening of the packaging barrel 01. The electromagnetic adsorption head is in full contact with the cover body, which greatly increases the reliability and stability of opening the cover, reduces the impact of the coal dust environment on opening the cover, and has strong environmental adaptability.

[0065] Based on the above embodiment, the unsealing cover assembly 14 also includes a signal transmitter for sending an unlocking signal to the cover of the package barrel 01 that has been positioned before filling, and sending a locking signal to the cover after the filling is completed and the electromagnet adsorption head drives the cover to reset.

[0066] The signal transmitter of the unsealing lid assembly 14 is based on the password lid receiving controller of the packaging barrel 01 and its lid. In short, the signal transmitter of the unsealing lid assembly 14 can only send an opening signal and a locking signal to the packaging barrel 01 and its lid that are equipped with the aforementioned password lid receiving controller. After the signal transmitter sends the opening signal to the packaging barrel 01 and its lid, the radial restraining force between the packaging barrel 01 and the lid is lifted, and the unsealing lid assembly 14 drives the lid to move away from and closer to the packaging barrel 01 along the axial direction via the telescopic rod, thereby achieving opening and sealing. When the unsealing lid assembly 14 drives the lid to approach the packaging barrel 01 along the axial direction via the telescopic rod and contacts the packaging barrel 01, after the signal transmitter sends a locking signal to the packaging barrel 01 and its lid, the lid, under the action of the password lid receiving controller, applies a radial restraining force to the packaging barrel 01 to achieve locking.

[0067] The sample sorting and packaging system provided by the present invention also includes a circulating conveyor belt 4 located outside the main module 1. The inlet end of the circulating conveyor belt 4 is connected to the full barrel conveyor belt 3, and the outlet end of the circulating conveyor belt 4 is connected to the empty barrel conveyor belt 2. The empty barrel conveyor belt 2 is equipped with an empty barrel access control component 5, and the connection between the full barrel conveyor belt 3 and the circulating conveyor belt 4 is equipped with a packaging barrel reversing device.

[0068] The endless conveyor belt 4 can be driven by an endless conveyor belt motor 41 .

[0069] The packaging bucket reversing device is used to move partially filled packaging buckets 01 placed on the surface of the full bucket conveyor belt 3 onto the circulating conveyor belt 4. Therefore, in this embodiment, the filling material is distributed along both the surface of the conveyor belt 11 and the surface of the circulating conveyor belt 4. The partially filled packaging buckets 01 circulate within the closed loop formed by the conveyor belt 11, the partially full bucket conveyor belt 3, the circulating conveyor belt 4, and the partially empty bucket conveyor belt 2. Conversely, when the full bucket conveyor belt 3 moves a filled packaging bucket 01 out of the main module 1, the packaging bucket reversing device does not operate, and the filled packaging bucket 01 is discharged along the full bucket conveyor belt 3, completing the unloading of packaging buckets 01.

[0070] Based on the above structure, multiple packaging barrels 01 can be placed in a closed loop formed by the conveyor belt 11, the partially full barrel conveyor belt 3, the circulating conveyor belt 4, and the partially empty barrel conveyor belt 2. Multiple packaging barrels 01 can be used to load different types of materials. Since the main module 1 cannot fill a packaging barrel 01 completely in a single filling operation, and the materials transported by the main module 1 during multiple consecutive filling operations may belong to the same type of materials or different types of materials, the multiple packaging barrels 01 in the aforementioned closed loop circulate, and the main module 1 fills the same type of materials into the same packaging barrel 01. When the main module 1 transports materials that do not belong to the aforementioned packaging barrel 01 during the next filling operation, the closed loop drives all packaging barrels 01 to move until the packaging barrel 01 corresponding to the material moves to the filling position of the main module 1.

[0071] In this embodiment, empty packaging barrels 01 enter the main module 1 from the empty barrel conveyor belt 2. Because the empty barrel conveyor belt 2 is equipped with an empty barrel access control assembly 5, which is designed to prevent empty packaging barrels 01 from entering the empty barrel conveyor belt 2 when there are no empty spaces on the surface of the circulating conveyor belt 4, the empty barrel access control assembly 5 closes when there are no empty spaces on the surface of the circulating conveyor belt 4. However, the empty packaging barrels 01 are blocked by the empty barrel access control assembly 5 and cannot enter the main module 1 with the empty barrel conveyor belt 2. Only when there are empty spaces on the surface of the circulating conveyor belt 4 does the empty barrel access control assembly 5 open. At this point, the empty packaging barrels 01 enter the main module 1 with the empty barrel conveyor belt 2, completing the loading of packaging barrels 01. Thus, the empty barrel access control assembly 5 cooperates with the empty barrel conveyor belt 2 to load packaging barrels 01, ensuring that the closed loop in this embodiment is always full of packaging barrels 01, ready for filling of different types of materials.

[0072] To achieve better technical results, a refill access control assembly 6 is installed at one end of the endless conveyor belt 4 near the empty barrel conveyor belt 2. This assembly is used to prevent unfilled packaging barrels 01 from moving onto the empty barrel conveyor belt 2 when there is space on the endless conveyor belt 4. This arrangement prevents packaging barrels 01 on the endless conveyor belt 4 from entering the empty barrel conveyor belt 2, giving way to the empty barrel conveyor belt 2 as the empty barrel conveyor belt 2 replenishes the main module 1, thereby preventing movement interference between the packaging barrels 01 on the endless conveyor belt 4 and the empty packaging barrels 01.

[0073] The refill access control assembly 6 can be electrically connected to the same control circuit as the packaging barrel reversing device. When the packaging barrel reversing device is inactive, no packaging barrels 01 are being unloaded from the closed loop, resulting in no empty spaces on the circulating conveyor, and the refill access control assembly 6 is inactive. When the packaging barrel reversing device is active, packaging barrels 01 are being unloaded from the closed loop, creating empty spaces on the circulating conveyor. The refill access control assembly 6 then actuates a number of times, corresponding to the number of actuations of the packaging barrel reversing device, to prevent unfilled packaging barrels 01 from being moved onto the empty barrel conveyor belt 2.

[0074] Furthermore, the full-bucket conveyor 3 is equipped with a full-bucket access control assembly 7, which is used to prevent unfilled packaging buckets 01 from moving off the full-bucket conveyor 3. The full-bucket access control assembly 7 is located adjacent to the packaging bucket reversing device. This configuration aims to prevent unfilled packaging buckets 01 from moving off the full-bucket conveyor 3, thereby providing the packaging bucket reversing device with ample response time and preventing malfunction of the packaging bucket reversing device.

[0075] For the sample separation and packaging system provided by the present invention, the main module access control component 18, the empty bucket access control component 5, the replenishing bucket access control component 6 and the full bucket access control component 7 can all refer to the gate lever settings in the prior art.

[0076] A second photoelectric switch 51 can be provided at the empty bucket access control assembly 5, a third photoelectric switch can be provided at the refill bucket access control assembly 6, and a fourth photoelectric switch 71 can be provided at the full bucket access control assembly 7. The second, third, and fourth photoelectric switches 51, 71 are used to detect the position of the packaging bucket 01, allowing the empty bucket access control assembly 5, the refill bucket access control assembly 6, and the full bucket access control assembly 7 to respond to the corresponding position information.

[0077] A second code reader / writer assembly 8 can also be installed at the end of the circulating conveyor belt 4 near the empty barrel conveyor belt 2. As the partially filled packaging barrels 01 circulate within the closed loop, the second code reader / writer assembly 8 reads the identity information of each partially filled packaging barrel 01, such as the type and origin (or production line) of the material already filled within the packaging barrel 01, the quality of the material already filled, and the number of times the material has been filled. Based on this information acquired by the second code reader / writer assembly 8 and the matching status of the material to be filled by the main module 1, the control unit of the main module 1 automatically adjusts the movement distance of the closed loop, ensuring that the material to be filled is accurately placed in the same packaging barrel 01.

[0078] The looping conveyor belt 4 employed in the present invention can be comprised of multiple, spliced ​​sub-belt sections; the belt surfaces of all sub-belts are connected end-to-end between the full bucket conveyor belt 3 and the empty bucket conveyor belt 2. This arrangement enhances the layout flexibility of the looping conveyor belt 4, allowing for easy addition and sub-belt adjustments, as well as adjustments to their connection locations, thereby varying the length and path of the looping conveyor belt 4. Similarly, the empty bucket conveyor belt 2 and the full bucket conveyor belt 3 can also be configured using multiple, spliced ​​sections.

[0079] Regarding the layout of the circulating conveyor belt 4, the empty barrel conveyor belt 2 and the full barrel conveyor belt 3 with a splicing structure, the present invention specifically provides three layout methods, which can be referred to respectively. Figure 2 、 Figure 8 and Figure 9 .

[0080] Because the loop conveyor belt 4, the empty bucket conveyor belt 2, and the full bucket conveyor belt 3 are spliced ​​and connected, the closed loop of the sample sorting and packaging system can simultaneously carry multiple, for example, 10 or more packaging buckets 01 in a circular motion, thus providing more than 10 workstations. To accommodate a larger number of workstations, the loop conveyor belt 4 can simply be extended, or the loop conveyor belt 4, the empty bucket conveyor belt 2, and the full bucket conveyor belt 3 can all be extended.

[0081] Compared with the existing technology, the above-mentioned sample sorting and packaging system has more workstations, is easy to expand, and has strong adaptability; it is flexible in layout and convenient for docking with other equipment; it is small in size and can adapt to layout in narrow spaces.

[0082] In any of the above embodiments, the sampling and packaging system also includes a controller electrically connected to the main module 1, the empty barrel access control component 5 and the packaging barrel reversing device; when the main module 1 is filled with the packaging barrel 01, the controller closes the packaging barrel reversing device and opens the empty barrel access control component 5.

[0083] The main module 1 is provided with a first code reading and writing component 16 for reading and writing material information to the packaging barrel 01; the material information includes material quality and material type;

[0084] The main module 1 uses the first code reader / writer component 16 to read the material information of the packaging barrel 01, thereby continuously or intermittently filling the designated packaging barrel 01 with the same type of material. During closed-loop operation, each packaging barrel 01 on the closed-loop will pass through the first code reader / writer component 16. The code reader component obtains the material information of each packaging barrel 01 for matching with the coal sample information of the material transported to the main module 1. If the matching is unsuccessful, the closed-loop operation continues, and no packaging barrel 01 is secured by the clamping and positioning component 12. If the matching is successful, the corresponding packaging barrel 01 is secured by the clamping and positioning component 12, and the closed-loop operation stops, waiting for the filling of the aforementioned packaging barrel 01 to be completed.

[0085] The controller controls the main module 1, the empty bucket access control assembly 5, and the packaging bucket reversing device to circulate a designated packaging bucket 01 on the closed loop to the filling position of the main module 1, thereby filling the packaging bucket 01 with the work material. In addition to matching the packaging bucket 01 with the work material and controlling the main module 1 to achieve filling and capping, the controller also controls the empty bucket access control assembly 5 to load the packaging bucket 01 and the packaging bucket reversing device to unload the packaging bucket 01.

[0086] It should be noted that the above-mentioned controller and the control units in some specific embodiments are all control devices of the sample separation and packaging system. Therefore, the above-mentioned controller and the above-mentioned control unit can be integrated or separately provided.

[0087] The above is a detailed introduction to the sample separation and packaging system provided by the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
