Description

Technical Field

[0001] The present application relates to the technical field of feeding equipment, and in particular to an automatic filling system for industrial salt. Background Art

[0002] Industrial salt refers to salt substances used in various process flows in industrial production, including but not limited to sodium chloride, potassium chloride, calcium chloride, etc. These salts are widely used in chemical industry, metallurgy, food processing, medicine and other fields. Industrial salt usually has a high purity and the content of impurities must be strictly controlled to ensure that it plays the expected role in various industrial processes. However, due to its granular or powdered physical properties, industrial salt needs to be handled and filled with special equipment during storage, transportation and use to avoid pollution and waste.

[0003] In the related technologies, the filling methods of industrial salt are mainly manual filling and semi-automatic filling equipment. Manual filling usually requires operators to use bagged industrial salt to put it in batches, and use simple tools (such as shovels or funnels) to add industrial salt to the corresponding equipment. Semi-automatic filling equipment relies on vibration feeders, screw conveyors and other devices to transport and put salt. This type of equipment improves the efficiency of filling to a certain extent, but still requires manual intervention and cannot achieve fully automated operation.

[0004] In view of the above-mentioned related technologies, the filling method has the following shortcomings: First, the manual filling process is cumbersome and inefficient, especially when dealing with large batches of industrial salt, it often takes a long time and easily causes personnel fatigue; second, the use of semi-automatic filling equipment still requires manual quantitative delivery, and it is difficult to accurately control the amount of each filling, which easily leads to over- or under-filling and affects the stability of the production process. Therefore, there is an urgent need for an automated and precise industrial salt filling system to improve filling efficiency, reduce manual intervention, and improve the reliability and safety of the filling process.

[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The present application embodiment discloses an industrial salt automatic filling system. Figure 1 The automatic filling system for industrial salt includes a feeding bracket 1, a tray 2, a sliding platform 3, a lifting device 4, a supporting device 5, a clamping device 6, a transfer device and a control system (not shown in the figure). The feeding bracket 1 is provided with a first slide rail 11, a second slide rail 12, a third slide rail 13 and a fourth slide rail 14. The first slide rail 11 is arranged horizontally and located at the bottom of the feeding bracket 1, the fourth slide rail 14 is arranged horizontally and located at the top of the feeding bracket 1, the second slide rail 12 and the third slide rail 13 are both arranged vertically and located between the first slide rail 11 and the fourth slide rail 14, and the top and bottom of the second slide rail 12 and the third slide rail 13 are connected; the tray 2 is used to hold the salt bag, and the sliding platform 3 is slidably connected to the first slide rail 11 , used to send the tray 2 along the first slide rail 11 to the bottom of the second slide rail 12; the lifting device 4 is arranged between the second slide rail 12 and the third slide rail 13, and is used to control the tray 2 to be lifted and lowered along the second slide rail 12 or the third slide rail 13; a plurality of supporting devices 5 are arranged at intervals along the length direction of the second slide rail 12, and are used to support the tray 2 on the second slide rail 12; the clamping device 6 is slidably arranged on the fourth slide rail 14, and is used to clamp the salt bag on the tray 2 and put it into the transfer device; the transfer device is used to receive the salt bag from the clamping device 6, and transport the salt in the salt bag to the destination for feeding; the control system is used to control the sliding platform 3, the lifting device 4, the supporting device 5, the clamping device 6 and the transfer device.

[0030] When the automatic filling system for industrial salt is in operation, the staff places the salt bags on the pallet 2, and places the pallet 2 with the salt bags on the sliding platform 3 through a forklift or other means of transportation. The sliding platform 3 receives the control system command and moves along the first slide rail 11, so that the pallet 2 enters the bottom of the second slide rail 12. The lifting device 4 receives the control system command and lifts the pallet 2 along the second slide rail 12 to a specified height. The supporting device 5 supports the pallet 2 so that the pallet 2 loaded with salt bags is stabilized at the height. This cycle is repeated until all the pallets 2 carrying salt bags in this batch are stabilized on the second slide rail 12. The control system controls the transfer device to move to the feeding range of the clamping device 6 according to demand. The clamping device 6 clamps the salt bags on the second slide rail 12 and delivers them to the transfer device. After the transfer device receives the salt bags, it delivers the salt in the salt bags to the destination. During this process, the pallet 2 with the salt bags removed is transferred to the third slide rail 13 through the lifting device 4, and descends along the third slide rail 13 to the bottom of the loading bracket 1 for stacking. The subsequent staff will transfer the empty pallet 2 together to facilitate the filling of the next batch of salt. The entire filling process requires less manual intervention. Through automated and precise control of the stacking of salt bags and the delivery of salt, the reliability and safety of the filling process are improved, and the efficiency of the industrial salt filling system is greatly improved.

[0031] For details, please refer to Figure 2 and Figure 3 , two stop blocks 21 are integrally formed at both ends of the tray 2, so that the tray 2 can be stably lifted during the lifting process, the second slide rail 12 and the third slide rail 13 are both door-shaped, and the top and bottom of the second slide rail 12 and the third slide rail 13 are connected, so that the tray 2 can freely shuttle between the second slide rail 12 and the third slide rail 13. In order to improve the sliding stability of the sliding platform 3, the tray 2 and the clamping device 6, the first slide rail 11, the second slide rail 12, the third slide rail 13 and the fourth slide rail 14 are symmetrically provided with two along the vertical plane, and the second slide rail 12 and the third slide rail 13 are provided with a slide groove adapted to the stop block 21 on the tray 2, and the connecting section at the top of the second slide rail 12 and the third slide rail 13 is also provided with a slide groove and connected with the slide grooves of the second slide rail 12 and the third slide rail 13, and the bottom of the second slide rail 12 and the third slide rail 13 is provided with a notch, so that the stop block 21 can enter the second slide rail 12 or the third slide rail 13 in the horizontal direction.

[0032] Please refer to Figure 2 and Figure 4, two legs 22 are symmetrically provided at the bottom of the tray 2, and an avoidance groove 23 is formed between the two legs 22 and the bottom surface of the tray 2. The lifting device 4 includes a lifting slide 41 and a lifting bracket 42. The lifting slide 41 is vertically slidably arranged between the second slide rail 12 and the third slide rail 13. Specifically, the loading bracket 1 is vertically provided with a limit column between the second slide rail 12 and the third slide rail 13. The two ends of the lifting slide 41 are respectively sleeved between the two limit columns, so that the lifting slide 41 can be stably lifted and lowered. The lifting drive mode of the lifting slide 41 includes but is not limited to a sprocket chain or a linear motor drive mode; the lifting bracket 42 is a rectangular frame, and both ends of the top of the lifting bracket 42 are welded with limit strips 421. The lifting bracket 42 is slidably connected to the lifting slide 41 in the horizontal direction. The sliding drive mode of the lifting bracket 42 includes but is not limited to a gear rack or a cylinder drive mode. The thickness of the lifting bracket 42 is smaller than the thickness of the avoidance groove 23, so that the lifting bracket 42 can slide through the avoidance groove 23 to the bottom of the tray 2, and the lifting slide 41 slides upward to make the lifting bracket 42 abut against the bottom surface of the tray 2 and lift the tray 2. The two limit bars 421 can effectively reduce the possibility of the tray 2 detaching from the lifting bracket, and the limit bar 421 close to the second slide rail 12 can push the tray 2 from the second slide rail 12 to the third slide rail 13.

[0033] When the lifting device 4 lifts the tray 2 on the sliding platform 3 at the bottom of the second slide rail 12, please refer to Figure 4 and Figure 5 , the lifting bracket 42 slides horizontally to the range of the third guide rail, the lifting slide 41 drives the lifting tray 2 to lower the bottom of the third slide rail 13, the lifting bracket 42 slides horizontally and passes through the limiting groove at the bottom of the tray 2 to enter the range of the second slide rail 12, the lifting slide 41 drives the lifting bracket 42 to rise, and the tray 2 can be lifted; when the salt bag on the tray 2 is taken away, the lifting bracket 42 lifts the tray 2 from the bottom of the tray 2 to the top of the second slide rail 12, the lifting bracket 42 slides horizontally, and the limiting strip 421 on the lifting bracket 42 drives the tray 2 to the range of the third slide rail 13, the lifting slide 41 drives the lifting bracket 42 to descend to the bottom of the third slide rail 13, and the empty tray 2 can be unloaded.

[0034] The supporting device 5 includes a supporting support 51, a supporting plate 52 and a supporting drive. The supporting support 51 is vertically adjustable and arranged on the loading bracket 1. The adjustment drive of the supporting support 51 includes but is not limited to a linear motor or a gear rack and other driving methods. The supporting plate 52 is rotatably connected to the supporting support 51. Specifically, the supporting plate 52 can be rotated to a horizontal state (supporting state) or a vertical state (storage state). The supporting drive is used to drive the supporting plate 52 to rotate between the supporting state and the storage state. The supporting drive includes but is not limited to a servo motor or an electric push rod 87. The supporting devices 5 are grouped in two, and the two supporting devices 5 of the same group are symmetrically arranged on both sides of the loading bracket 1, so that two supporting plates 52 of the same height support the two ends of the tray 2 respectively, thereby improving the stability of the tray 2.

[0035] When the supporting device 5 supports the pallet 2, the supporting drive drives the supporting plate 52 to rotate from the storage state to the supporting state, thereby supporting the pallet 2. The supporting device 5 is adjustable in vertical position, so that the spacing between multiple supporting devices 5 can be adjusted, so that the filling system can adapt to salt bags of different specifications.

[0036] Please refer to Figure 6 The clamping device 6 includes a clamping bracket 61, a clamping claw 62 and an adjusting component. The clamping bracket 61 is slidably connected to the fourth slide rail 14. The sliding drive of the clamping bracket 61 includes but is not limited to a linear motor or a sprocket chain drive. The clamping claw 62 is an electric clamping claw, and there are multiple clamping claws. In this embodiment, there are four clamping claws 62, and the four clamping claws 62 are respectively used to clamp the four corners of the salt bag. The clamping claws 62 are movably arranged on the clamping bracket 61, and the adjusting component is used to control the clamping claws 62 to align with the four corners of the salt bag.

[0037] The adjustment component includes a clamping jaw bracket 63, an adjustment rod 64 and a visual sensor (not shown in the figure). The clamping jaw bracket 63 is slidably connected to the clamping bracket 61 in the longitudinal direction. The sliding drive of the clamping jaw bracket 63 includes but is not limited to a linear motor or a sprocket chain drive. The adjustment rod 64 is provided with multiple and corresponds to multiple clamping jaws 62 one by one. One end of the adjustment rod 64 is rotatably connected to the clamping bracket 61, and the rotating shaft is arranged in the longitudinal direction. The rotation drive of the adjustment rod 64 includes but is not limited to a micro motor or a micro cylinder drive, and the other end of the adjustment rod 64 is fixedly connected to the tail of the clamping jaw 62; the visual sensor is arranged at the bottom of the clamping jaw bracket 63, and the visual sensor identifies the boundary position of the salt bag through visual sensing, and cooperates with the control system to control the clamping jaw 62 to align with the corner position of the salt bag.

[0038] When the control system receives the salt adding signal, it controls the clamping bracket 61 to move to the top of the second slide rail 12 so that the clamping claw 62 is located directly above the tray 2. The position of the salt bag is identified by the visual sensor, and one of the corners of the salt bag is found. The adjustment component drives the clamping claw 62 to grab the corner of the salt bag and drag the salt bag to move slightly laterally so that the other corners of the salt bag are completely exposed. The visual sensor identifies the position of the salt bag again and locates the four corners of the salt bag. The adjustment component controls the four clamping claws 62 to grab the four corners of the salt bag respectively, so as to achieve stable grabbing of the salt bag. After the grabbing is completed, the clamping bracket 61 slides to the delivery area and delivers the salt bag to the transfer device for transportation.

[0039] The following is a detailed description of the transfer device, please refer to Figure 7-9 The transfer device includes an AGV trolley 7, a puncture device 8 and a feeding device 9. The puncture device 8 is used to puncture the salt bag so that the salt in the salt bag flows into the feeding device 9, and the feeding device 9 transports the salt to the destination. The control system can accurately control the AGV trolley 7 to enter the feeding range of the clamping device 6. After completing the feeding of the salt bag, the AGV trolley 7 carries the salt bag to the salt adding destination. During this period, the puncture device 8 punctures the salt bag so that the salt in the salt bag flows to the feeding device 9. When the AGV trolley 7 arrives at the salt adding destination, the feeding device 9 completes the transportation and feeding of the salt. The entire feeding process is a machine automation process, thereby improving the reliability and safety of the feeding process, and then greatly improving the efficiency of the industrial salt filling system.

[0040] The unloading device 9 includes a unloading hopper 91 and a screw conveyor 92. Both the unloading hopper 91 and the screw conveyor 92 are mounted on the top of the AGV trolley 7. The unloading hopper 91 is a conical hopper. The feed port of the screw conveyor 92 is connected with the discharge port of the unloading hopper 91. The piercing device 8 pierces the salt bag to allow the salt in the salt bag to flow into the feed hopper. By starting the screw conveyor 92, the salt in the feed hopper can be transported to the salt adding destination.

[0041] The puncture device 8 includes a puncture bracket 81, a material receiving plate 82, a supporting fence 83, a push plate 84 and a cutting knife 85. The puncture bracket 81 is L-shaped and stands horizontally on the AGV trolley 7. The material receiving plate 82 is fixedly set on the puncture bracket 81. The supporting fence 83 is located on one side of the material receiving plate 82 and is directly above the lower hopper 91. The supporting fence 83 includes a plurality of fence rods arranged at intervals along the horizontal direction. The cutting knife 85 passes through the gap between two of the fence rods to the top of the supporting fence 83, and the blade faces the supporting plate 52. The push plate 84 is located above the supporting plate 52. The push plate 84 is slidably connected to the puncture bracket 81 along the horizontal direction. The sliding drive of the push plate 84 includes but is not limited to a linear motor or a sprocket chain. In this embodiment, the material receiving plate 82 and the supporting fence 83 are located at the same height, and the bottom surface of the push plate 84 is close to but not abutting the top surface of the material receiving plate 82. The push plate 84 is provided with a notch for avoiding the cutting knife 85, so that the push plate 84 can push the salt bag to completely pass through the cutting knife 85, so that the salt bag is completely cut open, thereby reducing the residual amount of salt in the salt bag.

[0042] After the clamping device 6 puts the salt bag into the receiving plate 82, the push plate 84 slides horizontally, so that the salt bag is pushed from the receiving plate 82 to the supporting fence 83. When the salt bag passes through the cutting knife 85, the bottom of the salt bag is cut by the cutting knife 85, and the salt in the salt bag flows into the lower hopper 91 under the action of gravity, thereby facilitating the release of the salt in the salt bag.

[0043] After the salt bag is cut, some salt will be retained on both sides of the incision of the salt bag, resulting in the inability to discharge the salt in the salt bag cleanly, causing salt waste. In order to improve the cleanliness of the discharge of the salt in the salt bag, two sets of material guide components 86 and synchronous drive components are symmetrically arranged under the supporting fence 83. The synchronous drive component is used to drive the two sets of material guide components 86 to squeeze the salt bag, so that the salt in the salt bag flows close to the incision, thereby improving the cleanliness of the discharge of the salt in the salt bag. For details, please refer to Figure 8 The material guide assembly 86 includes a rotating rod 861 and a plurality of guide rods 862. The rotating rod 861 is arranged in the horizontal direction and is rotatably connected to the puncture bracket 81. The plurality of guide rods are arranged at intervals along the length direction of the rotating lever. Each guide rod is located within the interval range of the fence rod, so that the guide rod can pass through the gap of the supporting fence 83 to squeeze the salt bag. The synchronous drive assembly includes two mutually meshing driving gears and a driving motor. The two driving gears are coaxially fixedly connected to the rotating shafts of the two rotating rods 861 respectively. The driving motor drives one of the rotating rods 861 to rotate, so that the driving gear drives the other rotating rod 861 to rotate in the opposite direction, so that the guide rods 862 on the two rotating rods 861 pass through the top surface of the supporting fence 83 and squeeze the salt bag from both sides of the salt bag. The rotating rod 861 should rotate at a low speed so that the two sides of the salt bag are slowly lifted and gradually form a V shape, so that the salt in the salt bag flows toward the incision in the middle of the salt bag, greatly improving the cleanliness of the salt discharged from the salt bag.

[0044] To facilitate the collection of empty salt bags, please refer to Fig. 9 A collecting groove is provided at one end of the puncture bracket 81 away from the receiving plate 82, and the collecting groove is located on the side of the supporting fence 83 away from the cutting knife 85. After the salt bag is discharged, the guide rod 862 is stored under the supporting fence 83 driven by the rotating rod 861, and the push plate 84 continues to push the salt bag toward the collecting groove, so that the salt bag falls into the collecting groove, thereby collecting the empty salt bag.

[0045] Since the empty salt bag is light, it is very easy to get stuck at the entrance of the collection tank, making it difficult for the salt bag to enter the collection tank. Therefore, a push rod 87 is provided above the collection tank so that it can be raised and lowered. The push rod 87 is a vertically arranged round rod. The push rod 87 is slidably connected to the puncture bracket 81 through a connecting frame. The lifting drive of the push rod 87 includes but is not limited to a cylinder or an electric push rod 87. When the salt bag is pushed to the top of the collection tank, the push rod 87 slides downward to push the salt bag into the collection tank, thereby collecting the empty salt bag and reducing the influence of the empty salt bag on the next puncture step to ensure the sustainable operation of the puncture device 8.

[0046] It should be noted that the salt bags in the embodiments of the present application can also be replaced by other materials with physical properties similar to salt.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
