Description

Technical Field

[0001] The present invention relates to the technical field of feeding, and in particular to an automatic material distributor and a material distribution method. Background Art

[0002] In the production of products, it is necessary to separate materials such as components from a material pile (a large amount of materials) to achieve material distribution, feeding or loading. In the prior art, generally, a vibrating disk is used to achieve material distribution, feeding or loading. The vibrating disk can arrange the materials in an orderly manner through vibration. However, during the vibration of a large amount of materials by the vibrating disk, the materials will jump, resulting in violent impact collisions between the materials and between the materials and the vibrating disk, which is likely to cause damage to the materials, and will also generate relatively large noise. In addition, the capacity of the vibrating disk for storing materials is small, and frequent replenishment of materials is required. Especially for some easily scratched materials, it is impossible to perform material distribution, feeding or loading through the vibrating disk; for example, the material distribution mechanism and the automatic material distribution system disclosed in the Chinese patent document with the application number 201710237636.1 in the existing patent. Therefore, the defects are very obvious, and a solution is urgently needed. Summary of the Invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide an automatic material distributor and a material distribution method.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] An automatic material distributor includes a material bin having a top port, a swing plate rotatably connected to the inner wall of the material bin, a swing driving mechanism installed in the material bin and used to drive the swing plate to swing, a material distribution carrier mold arranged in the material bin in a lifting manner and located outside one end of the swing plate, a lifting driving mechanism installed in the material bin and used to drive the material distribution carrier mold to lift, and a surplus material cleaning mechanism arranged at the top of the material bin and used to clean the surplus materials on the material distribution carrier mold. A baffle plate extending downward is installed on one side of the material distribution carrier mold close to the swing plate, the side surface of the baffle plate is slidably connected to one end of the swing plate, the circumferential surface of the swing plate is slidably connected to the inner wall of the material bin, and a material storage space is formed among the swing plate, the inner wall of the material bin and the baffle plate. A material distribution cavity is recessed on the top surface of the material distribution carrier mold, and a material incoming sensor is embedded in the material distribution cavity. The lifting driving mechanism is electrically connected to the material incoming sensor.

[0006] Further, a plurality of support rods are linearly installed on the inner wall of the material bin, the support rods are located below the swing plate, and the support rods are used to support the swing plate.

[0007] Further, a hopper is installed on one side of the top port of the material bin, and the hopper is located above one end of the swing plate away from the material distribution carrier mold.

[0008] Further, a through hole communicating with the inner cavity of the silo is formed in the bottom surface of the silo, and the baffle plate can extend out of the bottom surface of the silo through the through hole.

[0009] Further, the surplus material cleaning mechanism includes a side enclosure plate installed on the outer side wall of the top port of the silo. The side enclosure plate is in a C shape. A plurality of air blowing holes are formed in the inner wall of the side enclosure plate. The material distribution and loading mold can rise into the side enclosure plate, and all the air blowing holes are arranged around the material distribution and loading mold. The gas blown out of the air blowing holes is used to blow the material into the material distribution cavity of the material distribution and loading mold or blow the surplus material on the material distribution and loading mold into the storage space.

[0010] Further, the surplus material cleaning mechanism includes a cleaning driver installed on the silo and a cleaning member installed on the driving end of the cleaning driver. The cleaning member is movably arranged above the top port of the silo. The cleaning driver is used to drive the cleaning member to move reciprocally. The cleaning member is used to scrape the material into the material distribution cavity of the material distribution and loading mold or scrape the surplus material on the material distribution and loading mold into the storage space.

[0011] Further, a detection sensor is installed on the silo. The detection sensor is used to detect the swing plate and is electrically connected to the swing driving mechanism.

[0012] Further, the swing driving mechanism includes a rotating shaft rotatably connected to the two inner side walls of the silo and a rotating driver installed on the silo and used to drive the rotating shaft or the swing plate to rotate. One end of the swing plate close to the baffle plate is installed on the peripheral wall of the rotating shaft.

[0013] Further, a guide plate is arranged in the silo. The guide plate is provided with an arc surface. One end of the swing plate far from the baffle plate is in sliding contact with the arc surface.

[0014] Further, a telescopic plate is elastically telescopically and slidably connected to the top surface of one end of the swing plate far from the baffle plate. The telescopic plate is in sliding contact with the inner wall of the silo.

[0015] Further, the swing plate is in an L shape. One end of the swing plate is installed on the rotating shaft. Two side baffle plates are arranged in parallel on both sides of the other end of the swing plate. The two side baffle plates and the swing plate enclose a semi-closed swing bin. The opening of the semi-closed swing bin faces downward to the material distribution and loading mold.

[0016] The present invention also provides a material distribution method. Based on the application of the above automatic material distribution machine, the specific method steps include:

[0017] 1). At the beginning, the material distribution and loading mold is at the highest position. The top surface of the material distribution and loading mold is flush with the top end surface of the silo. The bottom side surface of the baffle plate abuts against one end of the swing plate. The swing plate is in a horizontal state. The swing plate, the baffle plate and the inner wall of the silo enclose a sealed storage space. A large amount of material is stored in the storage space. The swing plate bears the material in the storage space.

[0018] 2) When the incoming material sensor detects that there is no material in the material distribution cavity of the material distribution carrier mold, the incoming material sensor feeds back a signal to the lifting drive mechanism, causing the lifting drive mechanism to first drive the material distribution carrier mold to descend a preset distance, and the material in the storage space will move into the material distribution cavity of the material distribution carrier mold;

[0019] 3) When the incoming material sensor senses that there is material in the material distribution cavity, the incoming material sensor feeds back a signal to the lifting drive mechanism and the surplus material cleaning mechanism, causing the lifting drive mechanism to drive the material distribution carrier mold together with the material to rise to the highest position. Then, while the surplus material cleaning mechanism cleans the surplus material on the material distribution carrier mold, it also correctly / flatly loads the material in the material distribution cavity;

[0020] 4) After the external transfer manipulator takes away the material carried by the material distribution carrier mold, the incoming material sensor detects that there is no material in the material distribution cavity, and the incoming material sensor feeds back a signal to the lifting drive mechanism, causing the lifting drive mechanism to drive the material distribution carrier mold to descend a preset distance again according to the control of the program;

[0021] 5) When the height positions of the N - th descents of the material distribution carrier mold are the same, N≥1, N is a positive integer, and the incoming material sensor detects that there is no material in the material distribution cavity of the material distribution carrier mold, it proves that the material distribution carrier mold cannot load the material in the storage space when descending to this height position. Then the distance of the (N + 1) - th descent of the material distribution carrier mold will be greater than the distance of the N - th descent of the material distribution carrier mold. The height difference of each descent of the material distribution carrier mold is set to a fixed value in the program until the incoming material sensor detects that there is material in the material distribution cavity of the material distribution carrier mold;

[0022] 6) Repeat the above step actions to enable the material distribution carrier mold to continuously distribute and supply materials upward;

[0023] 7) In step 5), when the material distribution carrier mold descends to the lowest position and the incoming material sensor cannot detect that there is material in the material distribution cavity, it proves that the amount of material in the material bin is small. At this time, the swing drive mechanism drives one end of the swing plate away from the baffle plate to swing upward by a preset angle, causing the swing plate to continuously tilt to guide the material in the material bin to the material distribution cavity;

[0024] 8) In step 7), as time goes by or the material in the material bin decreases, the swing drive mechanism can control the swing angle range of the swing plate to gradually increase, so that the material in the material bin can smoothly enter the material distribution cavity of the material distribution carrier mold; when the swing plate swings upward to the limit angle position and the incoming material sensor cannot detect that there is material in the material distribution cavity, it proves that there is no material in the material bin. At this time, the machine stops working and issues an alarm to remind the operator to add material to the material bin.

[0025] Further, in step 2), the swing plate is fixed or driven by a swing driving mechanism to swing reciprocally within a preset range, so that the materials in the storage space can smoothly move into the material distribution cavity of the material distribution carrier mold.

[0026] Advantages of the present invention: In practical applications, at the beginning, the material distribution and loading mold is at the highest position, the top surface of the material distribution and loading mold is flush with the top end surface of the bin, the bottom side of the material baffle is in contact with one end of the swing plate, the swing plate is in a horizontal state, and the swing plate, the material baffle and the inner wall of the bin enclose a closed material storage space. A large amount of materials are stored in the material storage space / bin. The swing plate bears / supports the materials in the bin / material storage space. During operation, when the incoming material sensor detects that there is no material in the material distribution cavity of the material distribution and loading mold, the incoming material sensor feeds back a signal to the lifting drive mechanism, causing the lifting drive mechanism to first drive the material distribution and loading mold to descend a preset distance. During this process, the swing plate can either remain stationary or be driven by the swing drive mechanism to reciprocate within a preset range, so that the materials in the material storage space can smoothly move into the material distribution cavity of the material distribution and loading mold. When the incoming material sensor senses that there is material in the material distribution cavity, the incoming material sensor feeds back a signal to the lifting drive mechanism and the excess material cleaning mechanism, causing the lifting drive mechanism to drive the material distribution and loading mold together with the material to rise to the highest position. Then, while the excess material cleaning mechanism cleans the excess material on the material distribution and loading mold, it also correctly / flatly loads the material into the material distribution cavity. Preferably, the excess material cleaning mechanism can clean the excess material on the material distribution and loading mold into the bin / material storage space to achieve the recycling of the excess material. Finally, the external transfer manipulator can take away the material carried by the material distribution and loading mold to achieve the feeding of the material. When the incoming material sensor detects that there is no material in the material distribution cavity, the incoming material sensor feeds back a signal to the lifting drive mechanism, causing the lifting drive mechanism to drive the material distribution and loading mold to descend a preset distance again according to the program control. When the height of the material distribution and loading mold descending N (N≥1, N is a positive integer) times is the same (the distance of the material distribution and loading mold descending N times is the same), and the materials in the bin / material storage space do not enter the material distribution cavity of the material distribution and loading mold, it proves that the material distribution and loading mold cannot load the materials in the bin / material storage space when descending to this height position. Then the distance of the (N + 1)th descent of the material distribution and loading mold will be greater than the distance of the Nth descent of the material distribution and loading mold. The height difference of each descent of the material distribution and loading mold is set to a fixed value in the program, so that the materials in the bin / material storage space can enter the material distribution cavity of the material distribution and loading mold. Repeat the above actions to achieve the continuous upward material distribution and feeding of the material distribution and loading mold. When the material distribution and loading mold descends to the lowest position and the incoming material sensor cannot detect the material in the material distribution cavity, it proves that the amount of material in the bin / material storage space is small. At this time, the swing drive mechanism drives the end of the swing plate away from the material baffle to swing upward to the limit angle position, causing the swing plate to continue to tilt, so as to tilt and guide the materials in the bin / material storage space into the material distribution cavity. When the swing plate swings to the limit angle position and the incoming material sensor cannot detect the material in the material distribution cavity, it proves that there is no material in the bin / material storage space. At this time, the machine stops working and issues an alarm to remind the operator to add materials to the bin / material storage space.Of course, as time goes by or the material in the silo / storage space decreases, the swing drive mechanism can control the swing angle range of the swing plate to gradually increase, so that the material in the silo / storage space can smoothly enter the material distribution cavity of the material distribution and loading mold. The silo of the present invention has a large capacity for storing materials, good stability in material distribution and feeding, does not require a vibrating disk for feeding, solves the problems of material scratching and high noise caused by using a vibrating disk for feeding during production, does not damage the material, reduces noise, and has good versatility, and can realize the material distribution and feeding of a variety of materials.

[0039] For the convenience of understanding by those skilled in the art, the present invention will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the implementation mode does not limit the present invention.

[0040] As Figures 1 to 10 shown, an automatic material distributor provided by the present invention includes a silo 1 having a top port, a swing plate 2 rotatably connected to the inner wall of the silo 1, a swing drive mechanism 3 installed in the silo 1 and used to drive the swing of the swing plate 2, a material distribution and mold loading 4 arranged in the silo 1 and located outside one end of the swing plate 2, a lifting drive mechanism 5 installed in the silo 1 and used to drive the lifting of the material distribution and mold loading 4, and a scrap cleaning mechanism 6 arranged at the top of the silo 1 and used to clean the excess material on the material distribution and mold loading 4. A downwardly extending material baffle 7 is installed on the side of the material distribution and mold loading 4 close to the swing plate 2. The side surface of the material baffle 7 is slidably connected to one end of the swing plate 2. The circumferential surface of the swing plate 2 is slidably connected to the inner wall of the silo 1. A storage space 8 is formed between the swing plate 2, the inner wall of the silo 1 and the material baffle 7. A material distribution and loading cavity 9 is recessed on the top surface of the material distribution and mold loading 4. An incoming material sensor 10 is embedded in the material distribution and loading cavity 9. The lifting drive mechanism 5 is electrically connected to the incoming material sensor 10.

[0041] In practical applications, at the beginning, the material distribution and loading mold 4 is at the highest position, the top surface of the material distribution and loading mold 4 is flush with the top end surface of the material bin 1, the bottom side of the material blocking plate 7 abuts against one end of the swing plate 2, the swing plate 2 is in a horizontal state, and the swing plate 2, the material blocking plate 7 and the inner wall of the material bin 1 enclose a closed material storage space 8. A large amount of materials are stored in the material storage space 8, and the swing plate 2 bears / supports the materials in the material storage space 8. During operation, when the incoming material sensor 10 detects that there is no material in the material distribution cavity 9 of the material distribution and loading mold 4, the incoming material sensor 10 feeds back a signal to the lifting drive mechanism 5, so that the lifting drive mechanism 5 first drives the material distribution and loading mold 4 to descend a preset distance. During this process, the swing plate 2 can either remain stationary or be driven by the swing drive mechanism 3 to swing reciprocally within a preset range, so that the materials in the material storage space 8 can smoothly move into the material distribution cavity 9 of the material distribution and loading mold 4. When the incoming material sensor 10 senses that there is material in the material distribution cavity 9, the incoming material sensor 10 feeds back a signal to the lifting drive mechanism 5 and the redundant material cleaning mechanism 6, so that the lifting drive mechanism 5 drives the material distribution and loading mold 4 together with the materials to rise to the highest position. Then, while the redundant material cleaning mechanism 6 cleans the redundant materials on the material distribution and loading mold 4, it also correctly / flatly loads the materials into the material distribution cavity 9. Preferably, the redundant material cleaning mechanism 6 can clean the redundant materials on the material distribution and loading mold 4 into the material bin 1 / the material storage space 8 to realize the recycling of the redundant materials. Finally, the external transfer manipulator can take away the materials carried by the material distribution and loading mold 4 to realize the feeding of the materials; when the incoming material sensor 10 detects that there is no material in the material distribution cavity 9, the incoming material sensor 10 feeds back a signal to the lifting drive mechanism 5, so that the lifting drive mechanism 5 drives the material distribution and loading mold 4 to descend a preset distance again according to the control of the program. When the height of the material distribution and loading mold 4 descending N (N≥1, N is a positive integer) times is the same (the distance of the material distribution and loading mold 4 descending N times is the same), and the materials in the material bin 1 / the material storage space 8 do not enter the material distribution cavity 9 of the material distribution and loading mold 4, it proves that the material distribution and loading mold 4 cannot load the materials in the material bin 1 / the material storage space 8 when descending to this height position. Then the distance of the (N + 1)th descent of the material distribution and loading mold 4 will be greater than the distance of the Nth descent of the material distribution and loading mold 4. The height difference of each descent of the material distribution and loading mold 4 is set to a fixed value in the program, so that the materials in the material bin 1 / the material storage space 8 can enter the material distribution cavity 9 of the material distribution and loading mold 4. Repeat the above actions to realize that the material distribution and loading mold 4 can continuously distribute and feed materials upward;When the material distribution and loading mold 4 descends to the lowest position and the incoming material sensor 10 fails to detect the material in the material distribution cavity 9, it proves that the amount of material in the material bin 1 / storage space 8 is small. At this time, the swing drive mechanism 3 drives the swing plate 2 to swing upward to the limit angle position at the end away from the material blocking plate 7, causing the swing plate 2 to continuously tilt, so as to tilt and guide the material in the material bin 1 / storage space 8 into the material distribution cavity 9. When the swing plate 2 swings to the limit angle position and the incoming material sensor 10 fails to detect the material in the material distribution cavity 9, it proves that there is no material in the material bin 1 / storage space 8. At this time, the machine stops working and issues an alarm to remind the operator to add material to the material bin 1 / storage space 8. Of course, as time goes by or the material in the material bin 1 / storage space 8 decreases, the swing drive mechanism 3 can control the swing angle range of the swing plate 2 to gradually increase, so that the material in the material bin 1 / storage space 8 can smoothly enter the material distribution cavity 9 of the material distribution and loading mold 4. The material bin 1 of the present invention has a large capacity for storing materials, good stability in material distribution and feeding, does not require feeding by a vibrating disk, solves the problems of scratching materials and high noise caused by feeding with a vibrating disk during production, does not damage materials, reduces noise, and has good versatility, and can realize the distribution and feeding of various materials.;

[0042] Specifically, the depth of the material distribution cavity 9 is a positive integer multiple of the thickness of the material; this structural design enables the material distribution cavity 9 to load multiple materials at one time, and the multiple materials are stacked, improving the efficiency of upward material distribution and feeding.

[0043] Specifically, the number of incoming material sensors 10 is one or more. The multiple incoming material sensors 10 detect the material in the material distribution cavity 9, improving the stability of material detection, preventing the problem that one incoming material sensor 10 cannot detect the material due to grooves in the material itself, and being able to identify the front and back of materials with different front and back sides.

[0044] In this embodiment, several support rods 11 are linearly installed on the inner wall of the material bin 1. The support rods 11 are located below the swing plate 2 and are used to support the swing plate 2. When the swing plate 2 is in a horizontal state, at this time, the amount of material in the storage space 8 is large, and the load borne by the swing plate 2 is large. Therefore, the horizontal swing plate 2 is supported by the support rods 11, playing a protective role for the swing plate 2.

[0045] In this embodiment, a hopper 12 is installed on one side of the top port of the material bin 1. The top port of the hopper 12 is in a flared shape, and the hopper 12 is located above the end of the swing plate 2 away from the material distribution and loading mold 4. In practical applications, when it is necessary to add material to the material bin 1, the operator adds material to the hopper 12, and the material in the hopper 12 moves into the inner cavity of the material bin 1, so that the material is stored in the inner cavity / storage space 8 of the material bin 1, facilitating the operator to add material to the inner cavity / storage space 8 of the material bin 1.

[0046] Specifically, two insertion rods 13 are installed at the top port of the silo 1, and two slots are recessed at the bottom port of the hopper 12. When the hopper 12 is assembled on the silo 1, the two insertion rods 13 are respectively inserted into the two slots to achieve the positioning and assembly of the hopper 12 and the silo 1, improving the position accuracy and stability of the hopper 12 assembled on the silo 1, and facilitating the disassembly and assembly of the hopper 12 and the silo 1.

[0047] Specifically, a handle 14 is provided on the outer side wall of the hopper 12, and the provision of the handle 14 facilitates the operator to pick up the hopper 12.

[0048] In this embodiment, a through hole communicating with the inner cavity of the silo 1 is opened on the bottom surface of the silo 1, and the baffle 7 can extend out of the bottom surface of the silo 1 through the through hole. This structural design enables the silo 1 not to hinder the baffle 7 from rising and falling with the material distribution carrier mold 4, makes the structure of the baffle 7 and the silo 1 compact, and the through hole plays a guiding role in the rising and falling of the baffle 7, making the rising and falling of the baffle 7 and the material distribution carrier mold 4 more stable.

[0049] In this embodiment, the residual material cleaning mechanism 6 includes a side enclosure plate 15 installed on the outer side wall of the top port of the silo 1. The side enclosure plate 15 is in a U shape. A plurality of air blowing holes 16 are opened on the inner wall of the side enclosure plate 15. The plane height where the air blowing holes 16 are located is higher than the top surface of the material distribution carrier mold 4. The material distribution carrier mold 4 can rise into the side enclosure plate 15, and all the air blowing holes 16 are arranged around the material distribution carrier mold 4. The gas blown out of the air blowing holes 16 is used to blow the material into the material distribution cavity 9 of the material distribution carrier mold 4 or blow the excess material on the material distribution carrier mold 4 into the storage space 8.

[0050] In practical applications, when the material distribution carrier mold 4 together with the material rises to the highest position, the material distribution carrier mold 4 is located within the side enclosure plate 15, and all the air blowing holes 16 horizontally blow out positive pressure gas. This positive pressure gas can not only make the material evenly loaded in the material distribution cavity 9 (correct the material), but also blow the excess material on the material distribution carrier mold 4 away from the material distribution carrier mold 4 and drop back into the storage space 8 to achieve the sorting of the material loaded in the material distribution cavity 9 and the cleaning of the excess material on the material distribution carrier mold 4.

[0051] Specifically, the top port of the material distribution cavity 9 is in a flared horn shape, which is conducive to the smooth entry or removal of the material into or from the material distribution cavity 9.

[0052] Specifically, the side enclosure plate 15 includes three side plates, and the three side plates enclose a U shape. The air blowing holes 16 are communicated with a blower.

[0053] In this embodiment, the surplus material cleaning mechanism 6 includes a cleaning driver 17 installed in the material bin 1 and a cleaning member 18 installed at the driving end of the cleaning driver 17. The cleaning member 18 is movably arranged above the top port of the material bin 1. The cleaning driver 17 is used to drive the cleaning member 18 to reciprocate. The cleaning member 18 is used to scrape the material into the material distribution cavity 9 of the material distribution carrier mold 4 or scrape the surplus material on the material distribution carrier mold 4 into the storage space 8. Specifically, the cleaning driver 17 can be a cylinder.

[0054] In practical applications, when the material distribution carrier mold 4 rises to the highest position together with the material, the cleaning driver 17 drives the cleaning member 18 to translate from the outside to the inside above the material distribution carrier mold 4, so that the cleaning member 18 can push the surplus material on the material distribution carrier mold 4 back into the storage space 8 to achieve the cleaning of the surplus material.

[0055] Specifically, the cleaning member 18 can be a soft material member. The soft material member can be a brush, or there are air blowing holes 16 on the soft material member to realize the combination of air blowing and material pushing of the soft material member.

[0056] In this embodiment, the material bin 1 is equipped with a detection sensor 19. The detection sensor 19 is used to detect the swing plate 2 or the movement of the material. The detection sensor 19 is electrically connected to the swing driving mechanism 3. Specifically, the detection sensor 19 can be a pair of photoelectric sensors. In practical applications, when the detection sensor 19 detects the movement or passing of the material to form a high or low level signal, it proves that the material can move under the lifting swing of the swing plate 2, so that the material in the storage space 8 can move into the material distribution cavity 9. At this time, the detection sensor 19 feeds back a signal to the swing driving mechanism 3, and the lifting angle of the swing plate 2 does not need to continue to increase, so that the swing driving mechanism 3 stops driving the swing of the swing plate 2 or maintains the angle of the swing plate 2 at this time or maintains the angle range of the reciprocating swing of the swing plate 2.

[0057] In this embodiment, the swing driving mechanism 3 includes a rotating shaft 20 rotatably connected to the two inner side walls of the material bin 1 and a rotating driver 21 installed in the material bin 1 and used to drive the rotating shaft 20 or the swing plate 2 to rotate. One end of the swing plate 2 close to the baffle 7 is installed on the circumferential wall of the rotating shaft 20.

[0058] In practical applications, the swing driving mechanism 3 drives the swing plate 2 or the rotating shaft 20 to rotate according to program control, so that the swing plate 2 swings. The swinging swing plate 2 can make the material in the storage space 8 smoothly move into the material distribution cavity 9 of the material distribution carrier mold 4.

[0059] In this embodiment, a guide plate 22 is arranged in the silo 1. The guide plate 22 is provided with an arc surface 23. One end of the swing plate 2 away from the baffle plate 7 is in sliding contact with the arc surface 23. During the swinging process of the swing plate 2, the swing plate 2 is always in sliding contact with the arc surface 23, avoiding the generation of a gap between the swing plate 2 and the arc surface 23 and preventing the problem of material leakage.

[0060] Specifically, a positioning step 24 is recessed in the peripheral wall of the rotating shaft 20. One end of the swing plate 2 is mounted on the positioning step 24 via a locking member. The side surface of the baffle plate 7 is tangentially connected to the rotating shaft 20. Specifically, the locking member can be a locking bolt. When assembling the rotating shaft 20 and the swing plate 2, one end of the swing plate 2 is placed on the positioning step 24. The positioning step 24 positions the swing plate 2, improving the position accuracy and stability of the swing plate 2 assembled on the rotating shaft 20, and enabling relative rotation between the swing plate 2 and the rotating shaft 20.

[0061] Specifically, the lifting drive mechanism 5 includes a lifting driver 25 mounted on the silo 1 and a lifting plate 26 mounted on the lifting end of the lifting driver 25. The material distribution and loading mold 4 is mounted on the lifting plate 26. In practical applications, the lifting driver 25 drives the lifting plate 26 and the material distribution and loading mold 4 to lift and lower synchronously.

[0062] Preferably, the lifting driver 25 includes a mounting seat 27 mounted on the outer side wall of the silo 1, a lead screw 28 rotatably connected to the mounting seat 27, a guide rod 29 mounted on the mounting seat 27 and parallel to the lead screw 28, a lifting nut 30 threadedly sleeved on the lead screw 28, and a drive motor 31 mounted on the mounting seat 27 and used to drive the lead screw 28 to rotate. The lifting plate 26 is mounted on the lifting nut 30 and slidably penetrates through the guide rod 29. In practical applications, the drive motor 31 drives the lead screw 28 to rotate. Under the limitation of the lifting plate 26 and the guide rod 29, the rotating lead screw 28 drives the lifting nut 30 to move up and down along the axial direction of the lead screw 28. The lifting nut 30 moving up and down drives the lifting plate 26 to move up and down along the guide rod 29, and the lifting plate 26 moving up and down drives the material distribution and loading mold 4 to lift and lower.

[0063] Specifically, a lifting groove is formed in the side wall of the silo 1 in the height direction. The lifting plate 26 extends into the inner cavity of the silo 1 through the lifting groove, and the lifting plate 26 can lift and lower along the lifting groove. This structural design is beneficial for the lifting plate 26 to drive the material distribution and loading mold 4 in the silo 1 to lift and move, making the structure of the lifting plate 26 and the silo 1 compact, and the lifting groove plays a guiding role in the lifting and moving of the lifting plate 26, improving the moving stability of the lifting plate 26.

[0064] Specifically, a displacement sensor or a distance sensor is provided on the bottom surface of the material distribution and loading mold 4. The displacement sensor is used to detect the lifting displacement of the material distribution and loading mold 4, and the displacement sensor or the distance sensor is electrically connected to the lifting drive mechanism 5. The distance sensor is used to detect the distance between the material distribution and loading mold 4 and the bottom wall of the bin 1; preferably, the displacement sensor or the distance sensor can adopt a laser sensor. In practical applications, the lifting displacement (lifting distance) of the material distribution and loading mold 4 is detected by the displacement sensor or the distance sensor and fed back to the lifting drive mechanism 5, so as to improve the lifting position accuracy and stability of the lifting drive mechanism 5 for controlling the material distribution and loading mold 4.

[0065] In another embodiment, a telescopic plate 32 is elastically and slidably connected to the top surface of one end of the swing plate 2 away from the baffle plate 7, and the telescopic plate 32 is in sliding contact with the inner wall of the bin 1; specifically, a telescopic guide groove 33 is provided in the length direction of the swing plate 2, a fixed pull rod 34 is installed on the bottom surface of the swing plate 2, a moving pull rod 35 is installed on the bottom surface of the telescopic plate 32, and the fixed pull rod 34 and the moving pull rod 35 are connected through a tension spring 36. The moving pull rod 35 passes through the telescopic guide groove 33 and can move along the telescopic guide groove 33. The tension spring 36 is located below the bottom surface of the swing plate 2, and the moving pull rod 35 is located inside the fixed pull rod 34. The tension spring 36 is used to apply an outward pulling force to the moving pull rod 35. As the swing plate 2 swings in the bin 1, the telescopic plate 32 can adaptively elastically expand and contract, so that the end of the telescopic plate 32 is always in sliding contact with the inner wall of the bin 1, avoiding the problem of material leakage due to the generation of a gap between the swing plate 2 and the inner wall of the bin 1.

[0066] In one embodiment, an arc-shaped plate extends downward from one end of the swing plate 2 away from the baffle plate 7. The arc-shaped plate is slidably connected to the arc surface 23, and an arc-shaped rack is provided on the inner arc surface 23 of the arc-shaped plate. The rotation drive 21 includes a rotation motor installed on the outer side wall of the bin 1 and a gear sleeved on the output shaft of the motor. The gear is in meshing transmission with the arc-shaped rack. In practical applications, the rotation motor drives the gear to rotate, and the rotating gear meshes with the arc-shaped rack to drive the arc-shaped plate to swing, and the swinging arc-shaped plate drives the swing plate 2 to swing.

[0067] In another embodiment, as Figure 8 and 9 shown, the rotation drive 21 is located inside the bin 1 and is arranged between the bottom plate of the bin 1 and the swing plate 2. The rotation drive 21 can adopt an upward pushing drive structure to realize the reciprocating swing of the swing plate 2. The upper top plate of the upward pushing drive structure can support the swing plate 2 in a horizontal state, such as: a screw rod module, a cylinder, an oil cylinder and other upward pushing drive structures. In practical applications, the output end of the upward pushing drive structure abuts against the bottom surface of the swing plate 2. When the output end (upper top plate) of the upward pushing drive structure pushes the swing plate 2 upward, the swing plate 2 swings upward. When the output end (upper top plate) of the upward pushing drive structure descends or retracts, the swing plate 2 swings downward.

[0068] In yet another embodiment, as Figure 10 shown, the swing plate 2 is L-shaped. One end of the swing plate 2 is mounted on the rotating shaft 20. On both sides of the other end of the swing plate 20, two side baffles are arranged in parallel. The two side baffles and the swing plate 2 enclose a semi-closed swing bin. The opening of the semi-closed swing bin faces downward to the material distribution carrier mold 4. In practical applications, a large amount of materials are stored in the semi-closed swing bin. The rotating drive 21 drives the semi-closed swing bin to swing upward, and the materials in the semi-closed swing bin will slide into the material distribution cavity 9 of the material distribution carrier mold 4.

[0069] In yet another embodiment, the rotating drive 21 can be a rotating motor. The rotating motor is mounted on the outer side wall of the material bin 1. The output shaft of the rotating motor is drivingly connected to the rotating shaft 20 via a coupling. In practical applications, the output shaft of the rotating motor drives the rotating shaft 20 to rotate via the coupling, and the rotating rotating shaft 20 drives the swing plate 2 to swing.

[0070] The present invention also provides a material distribution method, based on the application of the above automatic material distributor. The specific method steps include:

[0071] 1) At the beginning, the material distribution carrier mold 4 is at the highest position. The top surface of the material distribution carrier mold 4 is flush with the top surface of the material bin 1. The bottom side of the material blocking plate 7 abuts against one end of the swing plate 2. The swing plate 2 is in a horizontal state. The swing plate 2, the material blocking plate 7 and the inner wall of the material bin 1 enclose a closed storage space 8. A large amount of materials are stored in the storage space 8, and the swing plate 2 bears the materials in the storage space 8.

[0072] 2) When the incoming material sensor 10 detects that there is no material in the material distribution cavity 9 of the material distribution carrier mold 4, the incoming material sensor 10 feeds back a signal to the lifting drive mechanism 5, so that the lifting drive mechanism 5 first drives the material distribution carrier mold 4 to descend a preset distance, and the materials in the storage space 8 will move into the material distribution cavity 9 of the material distribution carrier mold 4.

[0073] 3) When the incoming material sensor 10 senses that there is material in the material distribution cavity 9, the incoming material sensor 10 feeds back a signal to the lifting drive mechanism 5 and the surplus material cleaning mechanism 6, so that the lifting drive mechanism 5 drives the material distribution carrier mold 4 together with the materials to rise to the highest position. Then, while the surplus material cleaning mechanism 6 cleans the surplus materials on the material distribution carrier mold 4, it also correctly / flatly loads the materials in the material distribution cavity 9.

[0074] 4) After the external transfer manipulator takes away the materials carried by the material distribution carrier mold 4, the incoming material sensor 10 detects that there is no material in the material distribution cavity 9. The incoming material sensor 10 feeds back a signal to the lifting drive mechanism 5, so that the lifting drive mechanism 5 drives the material distribution carrier mold 4 to descend a preset distance again according to the control of the program.

[0075] 5) When the height positions of the material distribution and loading mold 4 after descending N times are the same, where N ≥ 1 and N is a positive integer, and when the incoming material sensor 10 detects that there is no material in the material distribution cavity 9 of the material distribution and loading mold 4, it proves that the material in the storage space 8 cannot be loaded when the material distribution and loading mold 4 descends to this height position. Then, the distance of the (N + 1)-th descent of the material distribution and loading mold 4 will be greater than the distance of the N-th descent of the material distribution and loading mold 4. The height difference of each descent of the material distribution and loading mold 4 is set to a fixed value in the program until the incoming material sensor 10 detects that there is material in the material distribution cavity 9 of the material distribution and loading mold 4;

[0076] 6) Repeat the above step actions to enable the material distribution and loading mold 4 to continuously distribute and supply materials upward;

[0077] 7) In step 5), when the material distribution and loading mold 4 descends to the lowest position and the incoming material sensor 10 fails to detect that there is material in the material distribution cavity 9, it proves that the amount of material in the material bin 1 is small. At this time, the swing drive mechanism 3 drives the swing plate 2 to swing upward by a preset angle at the end away from the baffle 7, so that the swing plate 2 continuously tilts to guide the material in the material bin 1 to the material distribution cavity 9 in an inclined manner;

[0078] 8) In step 7), as time goes by or the material in the material bin 1 decreases, the swing drive mechanism 3 can control the swing angle range of the swing plate 2 to gradually increase, so that the material in the material bin 1 can smoothly enter the material distribution cavity 9 of the material distribution and loading mold 4; when the swing plate 2 swings upward to the limit angle position and the incoming material sensor 10 fails to detect that there is material in the material distribution cavity 9, it proves that there is no material in the material bin 1. At this time, the machine stops working and issues an alarm to remind the operator to add material to the material bin 1.

[0079] In this embodiment, in step 2), the swing plate 2 remains stationary or is driven by the swing drive mechanism 3 to reciprocate within a preset range, so that the material in the storage space 8 can smoothly move to the material distribution cavity 9 of the material distribution and loading mold 4.

[0080] The material bin 1 of the present invention has a large capacity for storing materials, good stability in material distribution and supply, does not require feeding by a vibrating disk, solves the problems of scratching materials and high noise caused by feeding with a vibrating disk during production, does not damage the materials, reduces noise, and has good versatility, and can realize the distribution and supply of various materials.

[0081] All the technical features in this embodiment can be freely combined according to actual needs.

[0082] The above embodiments are the preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
