Description

Technical Field

[0001] The invention relates to the technical field of granular material packaging, in particular to an energetic material filling and weighing device. Background Art

[0002] The production line of granular materials usually includes a material packaging process, that is, the granular materials are weighed according to the specified amount and then sent to the next process.

[0003] At present, most of the material packaging and processing methods are as follows: ① Manual weighing and packaging, but the manual method not only has high labor costs, high labor intensity, low work efficiency, low weighing accuracy, and difficulty in unifying weighing quality, but is also not suitable for operation in special work scenarios.

[0004] ② Adopting an automated weighing and packaging method, such as configuring a feeding mechanism, a weighing device and a manipulator in the production line, wherein the feeding mechanism can be combined with a silo (or a vibrating plate) and a conveying channel according to demand, the weighing device is arranged at the discharge port of the conveying channel, and the manipulator can place or remove the receiving container on the weighing device, that is, the manipulator places the receiving container on the weighing device, and after the material delivered by the conveying channel falls into the receiving container, the manipulator removes the fully loaded receiving container from the weighing device and places it at a designated location. Although the above-mentioned automated weighing and packaging method saves manpower and improves work efficiency to a certain extent, it still has the following shortcomings: a) The feeding error of the feeding mechanism is large, resulting in low material packaging accuracy. b) The manipulator is responsible for transferring the receiving container, and needs to transfer between at least three stations, such as the supply station of the empty receiving container, the weighing station, and the unloading station of the full receiving container. There are many tasks, which can easily lead to slow processing and poor connection with the previous and next processes. If multiple manipulators are configured, it will increase production costs and occupy a large space, which cannot meet production requirements well.

[0005] In view of this, the present invention is proposed. Summary of the invention

The plurality of groups of receiving mechanisms 31 can be moved one by one to below the discharge port of the discharge bin 11 and to a preset material receiving station. When the receiving mechanisms 31 are moved to below the discharge port of the discharge bin 11, the receiving mechanisms 31 can control the receiving containers 30 to be arranged with the opening facing upwards. At that time, the container transfer mechanism 32 can transfer the receiving containers 30 to the receiving mechanisms 31. 1 and the weighing device 2 to transfer the receiving container 30 from empty to fully loaded. It can be understood that the container transfer mechanism 32 can transfer the empty receiving container 30 from the receiving mechanism 31 to the weighing device 2, and transfer the fully loaded receiving container 30 from the weighing device 2 to the receiving mechanism 31; and when the receiving mechanism 31 moves to the material receiving station, the receiving mechanism 31 can control the receiving container 30 to flip over, so as to tilt and pour the fully loaded receiving container 30.

[0043] From the above, it can be seen that ① on the one hand, the energetic material filling and weighing equipment described in this application integrates functions such as high-precision filling, high-precision weighing, high automation and intelligent unloading, with high integration, automation and intelligence, and high processing accuracy and processing efficiency; on the other hand, the structural design of the energetic material filling and weighing equipment described in this application is reasonable and novel, the various devices are organically coordinated and highly matched, and the explosion-proof performance is good, so that it can well meet the production needs of energetic materials. ② In the energetic material filling and weighing equipment described in this application, the connection between the filling device and the previous process, and between the material receiving and transferring device and the subsequent process are very smooth, which greatly improves the processing rhythm and processing stability of the entire production line. ③ The structural design of the energetic material filling and weighing equipment described in this application is simple, the production cost is controllable, and it occupies less space, which is conducive to production implementation. In addition, the energetic material filling and weighing equipment can also be applied to various granular materials and packaging operations in various work scenarios, and its versatility is very good.

[0044] The specific structure and working method of the energetic material filling and weighing equipment described in this embodiment are described in detail below.

[0045] First, let us discuss the filling device 1 .

[0046] In this embodiment, the filling device 1 is one of the core devices and is used to accurately fill the energetic material.

[0047] Please continue to refer to the attached Figure 1 To Attachment Fig. 9 As shown, in the structure of the filling device 1 described in this embodiment, the two groups of explosion-proof flow channels 10 are each provided with a flow channel body 100, an explosion-proof direct vibration feeder 101 connected to the flow channel body 100 and capable of driving the energetic material in the flow channel body 100 to flow along its feeding direction, and a protective cover 102 provided on the flow channel body 100; wherein, in order to achieve precise filling, the present embodiment, on the one hand, controls the vibration frequencies of the two explosion-proof direct vibration feeders 101 in the two groups of the explosion-proof flow channels 10 to be different, so that the feeding speeds of the two flow channel bodies 100 are different; on the other hand, it also controls the start and stop actions of the two explosion-proof direct vibration feeders 101 to be asynchronous, specifically: after the explosion-proof direct vibration feeder 101 with a large vibration frequency stops working, the explosion-proof direct vibration feeder 101 with a small vibration frequency is started to work. It can be understood that by performing the above-mentioned optimal control on the vibration frequency and working order of the two explosion-proof direct vibration feeders 101, the explosion-proof flow channel 10 with a high feeding speed (high vibration frequency) is responsible for the coarse feeding work, and the explosion-proof flow channel 10 with a low feeding speed (low vibration frequency) is responsible for the fine feeding work, thereby achieving high-precision and high-efficiency filling operations.

[0048] Furthermore, regarding the explosion-proof direct vibration feeder 101, a pneumatic explosion-proof direct vibration feeder or an electric explosion-proof direct vibration feeder can be used, among which the electric explosion-proof direct vibration feeder is preferred, which has the advantages of low noise, adjustable vibration frequency, high precision, etc., and is more suitable for various processing scenarios. As for the specific structure of the explosion-proof direct vibration feeder 101, the preferred design of this embodiment is as follows: Please refer to the attached Figure 4 and attached Figure 5 As shown, the explosion-proof direct vibration feeder 101 is provided with an upper mounting plate 1010 connected to the flow channel body 100, a lower fixing plate 1011 located below the upper mounting plate 1010, two spring sheets 1012 connected between the upper mounting plate 1010 and the lower fixing plate 1011, a plurality of rubber pads 1013 installed on the bottom side of the lower fixing plate 1011, a counterweight block 1014 installed on the lower fixing plate 1011, and a small explosion-proof vibration motor 1015 connected to the counterweight block 1014, through the operation of the small explosion-proof vibration motor 1015, the upper mounting plate 1010 can be driven to continuously perform high-frequency reciprocating motion to attach Figure 5 Taking the direction shown as a reference, the upper mounting plate 1010 can move back and forth between the upper left and lower right directions, thereby driving the energetic material in the flow channel body 100 to flow along the feeding direction (toward the left direction). In summary, ① by adopting the above-mentioned preferred design of the explosion-proof direct vibration feeder 101, the energetic material can be quickly and evenly spread over the entire flow channel surface in the flow channel body 100, avoiding the accumulation and agglomeration of energetic materials in the flow channel body 100, achieving efficient and orderly transportation of energetic materials, and greatly improving production efficiency. ② The explosion-proof direct vibration feeder 101 has good explosion-proof performance, which can greatly improve the safety of the explosion-proof flow channel 10 in special environments, and build a solid safety line for the stable operation of the entire production line.

[0049] As for the flow channel body 100, it can preferably adopt a long strip structure with a V-shaped vertical cross section (see the attached Figure 7 As shown in FIG. 1 ), this is more conducive to the flow and transportation of granular materials; one side of the flow channel body 100 in the length direction is open to form the discharge port of the flow channel body 100, and the other side of the flow channel body 100 in the length direction is closed to serve as the feeding side of the flow channel body 100; in addition, the two discharge ports of the flow channel body 100 are arranged opposite to each other (see FIG. 1 ). Figure 4 and attached Figure 6As shown in the figure, a sensor 13 (such as a through-beam sensor) is installed next to the feeding side of the two flow channel bodies 100 for real-time sensing of the feeding status of the energetic material in the flow channel body 100. When the sensor 13 detects that there is no energetic material in the flow channel body 100, the explosion-proof direct vibration feeder 101 will stop working and alarm to ensure the stability and safety of the production process.

[0050] Regarding the protective cover 102, it has an explosion-proof function and is fixedly disposed on the upper side of the flow channel body 100 to prevent the energetic material from splashing out of the flow channel body 100 during transportation. Preferably, the protective cover 102 can be made of explosion-proof glass, which not only has good explosion-proof performance, is conducive to the flat transportation of energetic materials, but also is easy to observe.

[0051] Furthermore, based on the working contents of the above two groups of explosion-proof flow channels 10, the flow channel body 100 connected to the explosion-proof direct vibration feeder 101 with a large vibration frequency is defined as a roughing flow channel body, and the flow channel body 100 connected to the explosion-proof direct vibration feeder 101 with a small vibration frequency is defined as a finishing flow channel body, wherein no functional parts are arranged in the roughing flow channel body, so under the drive of the explosion-proof direct vibration feeder 101, the energetic material can be quickly and evenly spread over the roughing flow channel body to achieve a large / large flow rate and efficient transportation of energetic materials; and in the finishing flow channel body, a plurality of the diverter components 12 are arranged at intervals along the feeding direction thereof to enable the energetic material located in the finishing flow channel body to flow into the lower bin 11 particle by particle to achieve precise transportation of energetic materials.

[0052] Please continue to refer to the attached Figure 7 To Attachment Fig. 9 As shown, the diverter 12 in this embodiment preferably adopts the following implementation structure: each of the diverters 12 is provided with a main body 120 and a diverter 121, wherein the main body 120 is a vertical plate structure matching the cross-sectional shape of the inner cavity of the finishing channel main body, and is fixedly built into the finishing channel main body, so as to divide the inner cavity of the finishing channel main body into a plurality of sub-chambers 1000 arranged at intervals along its feeding direction; the diverter 121 is a hole groove or through-hole structure integrally provided on the upper or lower part of the main body 120, and by optimizing the size of the diverter 121, the energetic material can be well diverted step by step and orderly in the above-mentioned plurality of sub-chambers 1000, so that the energetic material can be arranged and transported one by one in the last sub-chamber 1000 (i.e., a sub-chamber 1000 adjacent to and connected to the lower bin 11) until it flows into the lower bin 11. That is, the energetic materials in the finishing flow channel body can be diverted and combed step by step by means of the plurality of diverting members 12 , so that the energetic materials flow into the lower hopper 11 particle by particle.

[0053] The specific structure of the diverter 12 is further described as follows: Figure 7 Taking the V-shaped inner cavity cross-section of the fine flow channel body as an example, the main body 120 adopts a triangular plate structure accordingly; the diverter 121 can be a through hole structure provided on the lower part of the main body 120 (see the attached Figure 8 As shown in FIG. 1 ), it may also be a hole-groove structure provided on the upper portion of the main body 120 (see FIG. 1 ). Fig. 9 Of course, in practical applications, the shape of the main body 120 and the shape and layout of the diverter 121 are not limited to the above-mentioned situations.

[0054] Please continue to refer to the attached Figure 3 and attached Figure 4 As shown, in the structure of the filling device 1 described in this embodiment, the preferred implementation structure of the feed bin 11 is: the feed bin 11 is provided with a feed bin body 110 which is connected with the discharge ports of the two flow channel bodies 100, and a feed pipe 111 which is sleeved outside the discharge port of the feed bin body 110 and can move up and down, a valve is installed in the discharge port of the feed bin body 110, the feed port of the feed pipe 111 can be inserted into or detached from the material receiving container 30, and a lid 112 for closing the opening of the material receiving container 30 is fixedly sleeved outside the feed pipe 111. It can be understood that by designing the feed bin 11 as a split structure and designing the feed pipe 111 to be able to move up and down (the feed pipe 111 can be understood as an extension of the discharge port of the feed bin body 110), it is mainly to avoid the processing operation of the material receiving and transferring device 3 (especially the container transfer mechanism 32) described below, which is beneficial to the operation of the material receiving and transferring device 3 described below; and by providing the cover 112, it is to avoid the splashing of energetic materials and other adverse phenomena when the feed bin 11 is filling the material receiving container 30.

[0055] Further, the specific implementation structure of this embodiment to achieve the up and down movement of the feed pipe 111 is as follows: Figure 3 As shown, the filling device 1 is further provided with a lifting drive module 14, which is arranged beside the discharge bin 11 and can drive the discharge pipe 111 to move up and down. Furthermore, the lifting drive module 14 can adopt an explosion-proof cylinder or an explosion-proof motor and screw combination module, etc., which also has good explosion-proof performance.

[0056] Please continue to refer to the attached Figure 2 To Attachment Figure 4As shown, in the structure of the filling device 1 described in this embodiment, two loading bins 15 for accommodating energetic materials are further provided, and the two loading bins 15 are respectively corresponding to and sealedly connected with the loading sides of the two flow channel bodies 100. It can be understood that the two loading bins 15 are respectively used to supply materials to the two flow channel bodies 100.

[0057] Furthermore, the two loading bins 15 are respectively positioned above the loading sides of the two flow channel bodies 100 , and at the same time, the discharge ports of the two loading bins 15 are respectively sealed and extended into the loading sides of the two flow channel bodies 100 .

[0058] In addition, please refer to the attached Figure 1 To Attachment Figure 4 As shown, based on the above structural description of the filling device 1 described in this embodiment, the energetic material filling and weighing equipment is further provided with two feeding bins 4 and a chassis 16 connected to the upper station equipment, wherein the two feeding bins 4 are respectively connected and communicated with the two upper bins 15 through the explosion-proof flow channel A5, that is, it can be understood that the two feeding bins 4 are respectively used to feed materials to the two upper bins 15, and the explosion-proof flow channel A5 has the same structure as the explosion-proof flow channel 10 (so it will not be repeated here); the chassis 16 is used to receive the filling device 1 and the feeding bin 4, etc., as shown in the attached figure. Figure 1 and attached Figure 3 As shown, the feed bin 4 , the explosion-proof flow channel A5 , the upper bin 15 , the explosion-proof flow channel 10 and the lower bin body 110 are respectively installed on the top plate 160 of the chassis 16 , and the lifting drive module 14 is installed on the lower side of the top plate 160 .

[0059] Furthermore, in order to ensure that the energetic material is transported cleanly, the present embodiment further selectively installs a vibrator 6 on the feed bin 4, the upper bin 15 and the lower bin body 110 (see the attached Figure 6 And, to ensure the safety of energetic material transportation, the present embodiment also performs anti-static treatment on the feed bin 4, the upper bin 15, the lower bin body 110 and the lower pipe 111.

[0060] Next, let's talk about the weighing device 2 and the material transfer device 3.

[0061] Please continue to refer to the attached Figure 1 To Attachment Figure 3As shown, in this embodiment, the weighing device 2 preferably adopts an explosion-proof electronic scale, which is positioned below the discharge port of the discharge bin 11 through a support column 7, and a placement slot 20 for placing the receiving container 30 is provided on the weighing device 2. In addition, in this embodiment, a high-sensitivity pressure sensor is also configured on the weighing device 2, so that the weighing device 2 can respond quickly and accurately measure the weight of the energetic material.

[0062] Please continue to refer to the attached Figure 1 To Attachment Figure 3 , and attached Fig.10 As shown, in the structure of the receiving and transferring device 3 of this embodiment, the container transfer mechanism 32 is provided with a lifting cylinder 321 located beside the weighing device 2 and fixedly connected to the top of the support column 7 through a bracket 320, a clamping claw cylinder A322 fixedly connected to the power output end of the lifting cylinder 321, and a pair of contour clamping claws A323 fixedly connected to the clamping fingers of the clamping claw cylinder A322. The pair of contour clamping claws A323 can transfer the empty receiving container 30 from the receiving mechanism 31 to the placement slot 20, or transfer the fully loaded receiving container 30 from the placement slot 20 to the receiving mechanism 31 under the coordinated action of the clamping claw cylinder A322 and the lifting cylinder 321. In addition, in order to ensure the overall explosion-proof performance of the container transfer mechanism 32, the lifting cylinder 321 and the clamping claw cylinder A322 are both explosion-proof cylinders.

[0063] The structures of the plurality of material receiving mechanisms 31 are the same, and are all provided with a rotating cylinder 310, a clamping jaw cylinder B311 fixedly connected to the power output end (or called a turntable) of the rotating cylinder 310, and a pair of profiling jaws B312 fixedly connected to the clamping fingers of the clamping jaw cylinder B311, and the pair of profiling jaws B312 can clamp and fix the material receiving container 30. As mentioned above, the rotating cylinder 310 and the clamping jaw cylinder B311 are also explosion-proof cylinders.

[0064] The specific implementation structure that multiple groups of the material receiving mechanisms 31 can be moved one by one to the lower part of the material discharge port of the material discharge bin 11 and the preset material receiving station is as follows: the material receiving and transferring device 3 is also provided with an electric indexing turntable 33 (specifically driven to rotate by an explosion-proof motor) and a receiving plate 34 fixedly connected to the power output end of the indexing turntable 33, the indexing turntable 33 is fixedly connected to the top plate 160 through a connecting frame 35, and the rotating cylinders 310 of multiple groups of the material receiving mechanisms 31 are fixedly arranged on the receiving plate 34 at intervals. That is, through the driving of the indexing turntable 33, multiple groups of the material receiving mechanisms 31 can be moved one by one to the lower part of the material discharge port of the material discharge bin 11 and the material receiving station.

[0065] Next, about other institutions.

[0066] Please continue to refer to the attached Figure 1 As shown, according to production requirements, in this embodiment, a first receiving bin 81 for collecting qualified products and a second receiving bin 82 for collecting unqualified products are arranged in the receiving station according to the walking track of the receiving mechanism 31. In addition, vibrators are installed on both the first receiving bin 81 and the second receiving bin 82, so that the materials in the first and second receiving bins are stacked tightly.

[0067] Please continue to refer to the attached Figure 1 To Attachment Figure 3 As shown, according to production requirements, this embodiment is also provided with a material clearing mechanism, which is provided with a material receiving pipe 90, one end of which is connected to the material receiving container 91, and the other end of which can be connected to or separated from the material discharge port of the material discharge pipe 111. That is, when the energetic material filling and weighing equipment completes its work, the other end of the material receiving pipe 90 will move to connect to the material discharge port of the material discharge pipe 111, and at this time, the energetic material remaining in the material discharge bin 11 will flow into the material receiving container 91 through the material receiving pipe 90 for temporary storage, so as to avoid various potential problems caused by the residue in the material discharge bin 11.

[0068] Furthermore, the receiving tube 90 adopts an anti-static tube, and the cleaning mechanism is also provided with an explosion-proof rodless cylinder 92. The rodless cylinder 92 can be installed on the top plate 160 or the support column 7, and the rodless cylinder 92 can drive the other end of the receiving tube 90 to be close to or away from the discharge port of the discharge tube 111.

[0069] Finally, according to the above structural description of the energetic material filling and weighing device described in this embodiment, it can be known that the processing method of the energetic material filling and weighing device is:

[0070] S1: The energetic material obtained by the previous process flows into the feed bin 4, and then the explosion-proof flow channel A5 is started, so that the energetic material flows into the upper bin 15 with high efficiency and stability.

[0071] S2: Start the indexing turntable 33 and drive the receiving containers 30 (in an empty state) on one group of the receiving mechanisms 31 to move between the weighing device 2 and the unloading port of the unloading bin 11; then the lifting cylinder 321 drives the clamping cylinder A322 and the contour clamping claw A323 to rise together, and the clamping cylinder A322 drives the contour clamping claw A323 to close, so that the contour clamping claw A323 clamps the receiving container 30;

[0072] After the clamping jaw cylinder B311 on the receiving mechanism 31 drives the contour clamping jaw B312 to open, the lifting cylinder 321 drives the clamping jaw cylinder A322 and the contour clamping jaw A323 to descend together until the receiving container 30 is placed in the placement groove 20, and then the clamping jaw cylinder A322 drives the contour clamping jaw A323 to open;

[0073] Next, the lifting drive module 14 drives the feed tube 111 to descend and insert into the receiving container 30 . At this time, the cover 112 is closed on the opening of the receiving container 30 to prevent the energetic material from splashing.

[0074] S3: First start the roughing explosion-proof flow channel, and the energetic material therein is fed into the main body of the feeding bin 110 with large / or relatively large flow, high efficiency and high stability, and falls into the receiving container 30 through the feeding pipe 111; the weighing device 2 accurately weighs the energetic material falling into the receiving container 30 in real time, and when the weighing reaches the set value (generally set to be close to the rated value), the roughing explosion-proof flow channel stops working, and correspondingly, the fine-adding explosion-proof flow channel starts working, at which time the energetic material in the fine-adding explosion-proof flow channel is fed into the main body of the feeding bin 110 grain by grain, and falls into the receiving container 30 through the feeding pipe 111; when the weighing reaches the rated value, the valve in the main body of the feeding bin 110 is closed, and the fine-adding explosion-proof flow channel stops working. At that time, the precise filling operation is completed.

[0075] Note: ① The explosion-proof flow channel 10 of the explosion-proof direct vibration feeder 101 with a large vibration frequency is defined as a "rough explosion-proof flow channel", and the explosion-proof flow channel 10 of the explosion-proof direct vibration feeder 101 with a small vibration frequency is defined as a "fine explosion-proof flow channel". ② When performing the above-mentioned filling operation, the controller will analyze and judge the quality of the energetic material based on parameters such as filling weight and filling time. For example, if the filling weight is within the set weight threshold range, but the filling time is not within the set time threshold range, the controller will determine that the quality of the energetic material is poor.

[0076] S4: The lifting drive module 14 drives the material discharge pipe 111 to rise and separate from the material receiving container 30; then, the clamping claw cylinder A322 drives the contour clamping claw A323 to close, and the lifting cylinder 321 drives the clamping claw cylinder A322 and the contour clamping claw A323 to rise together, so that the fully loaded material receiving container 30 separates from the placement slot 20;

[0077] After the clamping jaw cylinder B311 on the receiving mechanism 31 drives the contour clamping jaw B312 to close and clamp the receiving container 30, the clamping jaw cylinder A322 drives the contour clamping jaw A323 to open, and the lifting cylinder 321 drives the clamping jaw cylinder A322 and the contour clamping jaw A323 to descend and reset together;

[0078] The indexing turntable 33 is started again, driving a group of the receiving mechanisms 31 receiving the fully loaded receiving containers 30 to move to the first receiving bin 81 or the second receiving bin 82 (determined according to the quality determination result of the energetic material), and at the same time driving another receiving mechanism 31 receiving the empty receiving container 30 to move between the weighing device 2 and the unloading port of the unloading bin 11. In addition, when the receiving mechanism 31 moves to the first receiving bin 81 or the second receiving bin 82, the rotating cylinder 310 drives the clamping cylinder B311 and the receiving container 30 thereon to rotate and unload the material.

[0079] S5: Repeat the above steps S2 to S4 until the filling and weighing process is completed.

[0080] S6: The rodless cylinder 92 drives the other end of the receiving tube 90 to connect with the discharge port of the discharge tube 111, so that the energetic material remaining in the discharge bin 11 flows into the receiving container 91 for temporary storage. After the material cleaning operation is completed, the rodless cylinder 92 drives the other end of the receiving tube 90 to reset.

[0081] From the above, it can be seen that the processing method of the energetic material filling and weighing equipment described in the present application is logically reasonable, and the operation is closely connected, efficient and orderly, thereby ensuring accurate and efficient processing of energetic materials.

[0082] Note: In this specification, the prefixes "first", "second", etc. of the component names (such as the first material receiving bin, the second material receiving bin, etc.), and the suffixes "A", "B", etc. of the component names (such as gripper cylinder A, gripper cylinder B, etc.) are only for the convenience of description and are not used to limit the scope of implementation of the patent of this invention.
