Description

Technical Field

[0001] The present invention relates to the field of material transportation, and particularly to a storage cabinet discharging device and a discharging method thereof. Background Art

[0002] Since the longitudinal section of the material accumulation in the storage cabinet is approximately trapezoidal, the amount of material at the head and tail sections is very small. When the storage cabinet discharges materials, the running speed of its conveying mechanism is constant, resulting in a small discharge amount at the head or tail stage, causing a drastic fluctuation in the material flow rate entering the downstream equipment, which has a greater impact on some key process parameter indicators. Especially in the tail stage, the material cannot be cleared for a long time, greatly lengthening the discharging time. Summary of the Invention

[0061] Next, the technical solutions in the embodiments will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0062] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the protection scope of the present invention.

[0063] In the related art, the longitudinal section of the material in the storage cabinet is approximately trapezoidal, and there is very little material at the head and tail sections. During the discharging stage of the material head, as the conveying mechanism 7 operates, the material between the subsequent material and the dialing roller is squeezed. Then the dialing nails rotate and tear the material and throw it down, resulting in the occurrence of crushing phenomenon. During the discharging stage of the material tail, the amount of material is small and there is no subsequent material to support it forward with the conveying mechanism 7. At this time, the material keeps rolling backward under the action of the dialing roller, resulting in the inability to clear it for a long time. Moreover, the waiting time for the whole production line to enter or transfer the cabinet due to the long tail material time is relatively long, making the production time tight. Furthermore, it will also cause severe fluctuations in the feeding accuracy or the moisture of the cut tobacco at the head and tail stages of the main equipment downstream of the storage cabinet, such as the feeding machine and the cut tobacco dryer.

[0064] Based on this, the present disclosure provides a storage cabinet discharging device for alleviating the problem of unstable material flow.

[0065] As Figures 1 to 4 shown, some embodiments provide a storage cabinet discharging device, which includes a storage cabinet 6, a first dialing roller mechanism 1, a second dialing roller mechanism 2 and a power mechanism 3.

[0066] The storage cabinet 6 is used for storing materials.

[0067] The first dialing roller mechanism 1 includes a first dialing roller 11 for loosening and dialing the material, and the first dialing roller 11 is arranged in the storage cabinet 6.

[0068] The second dialing roller mechanism 2 includes a second dialing roller 21 for loosening and dialing the material, and the second dialing roller 21 is arranged in the storage cabinet 6 and is located below the first dialing roller 11.

[0069] The power mechanism 3 is drivingly connected to the second dialing roller mechanism 2, and the power mechanism 3 is configured to drive the second dialing roller mechanism 2 to horizontally move in a direction close to or away from the first dialing roller mechanism 1.

[0070] Wherein, the first dialing roller 11 and the second dialing roller 21 are configured to work simultaneously or one of them works.

[0071] The first dialing roller 11 and the second dialing roller 21 are provided with a plurality of dialing nails along the extending direction of their own lengths.

[0072] During the head stock material discharging stage and the tail stock material discharging stage in the storage cabinet 6, the power mechanism 3 can drive the second roller mechanism 2 to move away from the first roller mechanism 1 and reach the first preset position; and control the first roller 11 not to work and the second roller 21 to work. During the intermediate material discharging stage between the head stock and the tail stock in the storage cabinet 6, the power mechanism 3 can drive the second roller mechanism 2 to move towards the first roller mechanism 1 and reach the second preset position, and control the first roller 11 and the second roller 21 to work simultaneously.

[0073] Therefore, for the storage cabinet material discharging device provided by the embodiments of the present disclosure, during the head stock material discharging stage when there is less material, the second roller 21 located below the first roller 11 is controlled to move away from the first roller 11 and work independently, avoiding the simultaneous operation of the first roller 11 and the second roller 21 and reducing the material crushing phenomenon. During the tail stock material discharging stage when there is less material, the material keeps turning over backward, causing the material to slip on the conveyor belt and unable to be cleared for a long time. By moving the second roller 21 away from the first roller 11 and working independently, it is beneficial to loosen the tail stock material and quickly dial it down. During the intermediate material discharging stage when there is more material, the first roller 11 approaches the second roller 21 and works simultaneously with the second roller 21, which is beneficial to loosen the material and quickly dial it down.

[0074] In some embodiments, the number of the first rollers 11 is two, and the first rollers 11 are arranged vertically one above the other, which is beneficial to loosen the material and quickly dial it down.

[0075] For example: as Figure 1 shown, the number of the first rollers 11 is two, the two first rollers 11 are arranged vertically one above the other, and both are located above the second roller 21.

[0076] In some embodiments, the first roller mechanism 1 further includes a first motor 12, a chain 13, and a plurality of sprockets 14. The first motor 12 is drivingly connected to one of the plurality of sprockets 14, each sprocket 14 is connected by the chain 13, and each sprocket 14 is correspondingly connected to a first roller 11. The first motor 12 is configured to provide power to rotate each first roller 11.

[0077] For example: as Figure 2 shown, the number of the first rollers 11 is two, the first roller mechanism 1 includes two sprockets 14, the two sprockets 14 are connected by the chain 13, the first motor 12 is drivingly connected to one of the two sprockets 14, and each sprocket 14 is connected to a first roller 11 through a connecting shaft.

[0078] In some embodiments, the second roller mechanism 2 further includes a second motor 22, and the second motor 22 is drivingly connected to the second roller 21 to rotate the second roller 21.

[0079] In some embodiments, such as Figure 3 shown, the power mechanism 3 includes a third motor 31, a slide rail 32, and a slider 33.

[0080] The slide rail 32 is provided at the bottom of the storage cabinet 6. The slider 33 is connected to the third motor 31 and the second roller mechanism 2. The third motor 31 is configured to provide power to enable the slider 33 to drive the second roller mechanism 2 to move horizontally relative to the first roller mechanism 1.

[0081] In some embodiments, the power mechanism 3 further includes a turbine 34 and a worm 35.

[0082] The turbine 34 is connected to the third motor 31.

[0083] The worm 35 is in meshing transmission with the turbine 34, and the worm 35 is connected to the slider 33.

[0084] The third motor 31 is configured to provide power to drive the turbine 34 to rotate. The turbine 34 meshes with the worm 35 to drive the worm 35 to move. The worm 35 drives the slider 33 to move horizontally, and further the slider 33 drives the second roller mechanism 2 to move horizontally relative to the first roller mechanism 1.

[0085] In some embodiments, the storage cabinet discharging device further includes a first detection element 41 and a second detection element 42 for detecting the materials in the storage cabinet 6. The first detection element 41 is provided above the second detection element 42.

[0086] The first roller 11 and the second roller 21 are configured to work simultaneously when both the first detection element 41 and the second detection element 42 detect materials.

[0087] The first roller 11 and the second roller 21 are configured to stop working for the first roller 11 and work for the second roller 21 when the first detection element 41 does not detect materials while the second detection element 42 detects materials.

[0088] Optionally, both the first detection element 41 and the second detection element 42 include photoelectric switches.

[0089] In some embodiments, the storage cabinet discharging device further includes a third detection element 43 and a fourth detection element 44 for detecting the position of the second roller mechanism 2. The third detection element 43 is closer to the first roller 11 than the fourth detection element 44.

[0090] The second roller mechanism 2 is configured to stop moving further when the third detection element 43 detects the second roller mechanism 2 during the process of moving in the direction close to the first roller 11.

[0091] The second roller mechanism 2 is configured to stop moving further when the fourth detection element 44 detects the second roller mechanism 2 during the movement in the direction away from the first roller 11.

[0092] Optionally, both the third detection element 43 and the fourth detection element 44 include proximity switches.

[0093] In some embodiments, as Figure 5 shown, the storage cabinet discharging device further includes a controller 5. The controller 5 is electrically connected to the first roller mechanism 1, the second roller mechanism 2, and the power mechanism 3. The controller 5 is configured to control the power mechanism 3 to drive the second roller mechanism 2 to move horizontally in the direction close to or away from the first roller 11; and control the first roller 11 and the second roller 21 to work simultaneously or alternatively, and control the rotation direction of the second roller 21.

[0094] Optionally, the controller 5 includes a PLC (programmable logic controller).

[0095] In some embodiments, the storage cabinet discharging device further includes a conveying mechanism 7. The conveying mechanism 7 is arranged below the storage cabinet 6 and is configured to transport the materials in the storage cabinet 6. The controller 5 is electrically connected to the conveying mechanism 7, and the controller 5 is configured to control the conveying speed of the conveying mechanism 7.

[0096] In some embodiments, the conveying mechanism 7 includes a conveyor belt and a motor.

[0097] In some embodiments, after the second roller 21 moves in the direction close to or away from the first roller 11, a proper gap is maintained between the second roller 21 and the conveyor belt of the conveying mechanism 7.

[0098] In some embodiments, the storage cabinet discharging device includes an independently operating first roller mechanism 1 and a second roller mechanism 2. Combined with the adjustable conveying speed of the conveying mechanism 7, it alleviates the problems of less discharging amount in the head or tail stage of the materials, unstable material flow rate, and severe fluctuation of the material flow rate entering the downstream equipment.

[0099] Some embodiments provide a discharging method for the above storage cabinet discharging device, which includes:

[0103] Among them, the first preset position is farther from the first roller mechanism 1 than the second preset position.

[0104] In some embodiments, in the head discharging stage of the materials in the storage cabinet 6 and the tail discharging stage of the materials in the storage cabinet 6, the second roller 21 rotates counterclockwise; In the intermediate discharging stage between the head and the tail of the materials in the storage cabinet 6, both the first roller 11 and the second roller 21 rotate clockwise.

[0105] In some embodiments, the storage cabinet discharging device includes a first detection element 41 and a second detection element 42 for detecting the materials in the storage cabinet 6;

[0106] When the first detection element 41 does not detect the materials and the second detection element 42 detects the materials, it is determined that it is in the head discharging stage of the materials in the storage cabinet 6 or the tail discharging stage of the materials in the storage cabinet 6.

[0107] When both the first detection element 41 and the second detection element 42 detect the materials, it is determined that it is in the intermediate discharging stage between the head and the tail of the materials in the storage cabinet 6.

[0108] In some embodiments, the storage cabinet discharging device includes a third detection element 43 and a fourth detection element 44 for detecting the position of the second roller mechanism 2, and the third detection element 43 is closer to the first roller 11 than the fourth detection element 44;

[0109] When the third detection element 43 detects the second roller mechanism 2, it is determined that the second roller mechanism 2 reaches the second preset position;

[0110] When the fourth detection element 44 detects the second roller mechanism 2, it is determined that the second roller mechanism 2 reaches the first preset position.

[0111] Optionally, when the second roller 21 reaches the second preset position, it is located diagonally below the first roller 1, and the first roller 1 is closer to the middle of the storage cabinet 6 than the second roller 21. In embodiments with more than two first rollers 1, the first rollers 1 are arranged vertically, and from top to bottom, the first rollers 1 are gradually arranged in a direction away from the middle of the storage cabinet 6.

[0112] In some embodiments, the storage cabinet discharging device further includes a conveying mechanism 7, and the conveying mechanism 7 is arranged below the storage cabinet 6 and is configured to transport the materials in the storage cabinet 6;

[0113] In the head discharging stage of the materials in the storage cabinet 6: The conveying mechanism 7 operates at a speed lower than the normal speed;

[0114] During the tail-end discharging stage in the storage cabinet 6: The conveying mechanism 7 operates at a speed higher than the normal speed;

[0115] During the intermediate discharging stage between the head and the tail in the storage cabinet 6: The conveying mechanism 7 operates at the normal speed.

[0116] The following lists a specific embodiment of the storage cabinet discharging device provided by the present disclosure, as well as the discharging method of the storage cabinet discharging device.

[0117] In this specific embodiment, the storage cabinet discharging device includes a first roller mechanism 1 and a second roller mechanism 2. The first roller mechanism 1 includes two first rollers 11, and the second roller mechanism 2 includes one second roller 21. The storage cabinet discharging device includes a first detection element 41, a second detection element 42, a third detection element 43, and a fourth detection element 44.

[0118] During the head-end discharging stage:

[0119] The two first rollers 11 in the first roller mechanism 1 are stationary; The fourth detection element 44 detects and corrects whether the second roller 21 is in the first preset position of the first roller 11. After the second roller 21 is in the first preset position, the controller 5 controls the second motor 22 to reverse, causing the second roller 21 to rotate counterclockwise. Since the mass of the materials in the storage cabinet 6 is very large when the cabinet is full, increasing the speed of the conveying mechanism 7 will cause a significant increase in the load of the transmission system. Therefore, during the head-end discharging stage, the conveying mechanism 7 operates at a constant speed lower than the normal speed. The second roller 21 loosens and quickly discharges the materials.

[0120] During the intermediate discharging stage:

[0121] When the first detection element 41 detects a high material level, it enters the in-material state. The third motor 31 provides power and drives the slider 33 through the transmission of the worm gear 34 and the worm 35. The slider 33 drives the second roller 21 to move towards the second preset position. When the third detection element 43 detects the second roller 21, the third motor 31 is powered off and the second roller 21 stops translating. The two first rollers 11 in the first roller mechanism 1 both rotate clockwise; The second roller 21 in the second roller mechanism 2 rotates from counterclockwise to clockwise under the control of the controller 5. The conveying mechanism 7 operates at a constant normal speed. Under the combined action of the first roller 11 and the second roller 21, the materials are loosened and evenly discharged.

[0122] Tail-end discharging stage:

[0123] When the second detection element 42 detects a low material level, it enters the tail material state. The two first rollers 11 in the first roller mechanism 1 are stationary. The third motor 31 provides power and drives through the worm gear 34 and the worm 35 to push the slider 33. The slider 33 drives the second roller 21 to move to the first preset position. When the fourth detection element 44 detects the second roller 21, the third motor 31 is powered off and the second roller 21 stops translating. The second roller 21 in the second roller mechanism 2 rotates counterclockwise from clockwise under the control of the controller 5. Since the amount of residual material in the storage cabinet is very small at the end of the material, the load of the conveying mechanism 7 is greatly reduced, making it possible for the conveying mechanism 7 to accelerate. At this time, the conveying mechanism 7 runs at a constant speed higher than the normal speed. Under the combined action of the conveying mechanism 7 and the second roller 21, the tail material smoothly and stably falls into the discharge port until the discharging is completed.
