Description

Technical Field

[0001] The invention relates to the technical field of tobacco shred conveying equipment, and in particular to a feeder and a feeding control method. Background Art

[0002] Bin feeders are widely used in the silk-making line in cigarette production. As a material buffer device, they are a device that uses volume to implement quantitative feeding of materials. Their main function is to buffer materials between processes to maintain the continuity of the production process and the quantitative supply of material flow, and to ensure the stability of the tobacco material supply flow, thereby achieving the function of material buffering and balanced material transportation for the front and rear processes of the silk-making production line. It is one of the important quantitative feeding equipment.

[0003] The existing silo feeder is mainly composed of a storage silo, a buffer silo and a lifting belt. The storage silo receives the materials conveyed by the upstream wire storage cabinet, and then conveys the materials to the downstream equipment through the buffer silo and the lifting belt. The materials loaded in the wire storage cabinet are approximately trapezoidal in shape. Therefore, in the actual production process, the discharge state of the wire storage cabinet can be divided into the head stage, the production stage and the tail stage. Specifically, when the storage silo receives the materials conveyed by the wire storage cabinet, it acts as a buffer for the materials, and the materials are piled up high. When the downstream of the feeder needs materials, the materials enter the buffer silo from the storage silo through the belt conveyor, and are lifted into the dropper after being leveled by the material roller in the lifting belt, and enter the downstream from the drop port. Because it is a silo-type equipment, there are more materials stored inside and the accumulation is high. When the equipment is running, the materials accumulated in the storage silo will fall into the buffer silo in the form of collapse. In order to ensure uniform and stable flow, the lifting belt needs to convey the materials in the buffer silo at a uniform speed, which causes a large amount of materials in the buffer silo to pile up and roll, increasing the material crushing, and then increasing consumption and cost. Summary of the invention

[0022] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a feeder, including: a wire storage cabinet 1, a material distribution pipe 2, a switching mechanism (not shown in the figure), a storage bin 3, and a lifting belt 4.

[0024] The wire storage cabinet 1 is used to store materials, and a wire storage cabinet tail material detection switch 11 is provided in the wire storage cabinet 1. The wire storage cabinet tail material detection switch 11 is used to detect whether the materials in the wire storage cabinet 1 have reached the tail material state. Specifically, when the wire storage cabinet tail material detection switch 11 does not detect the materials, it indicates that the materials in the wire storage cabinet 1 have reached the tail material state.

[0025] The material distribution pipe 2 has a material distribution pipe feed port 211 , a first material discharge port 221 and a second material discharge port 231 . The material distribution pipe feed port 211 is used to receive the material outputted from the wire storage cabinet 1 .

[0026] The switching mechanism is at least partially disposed in the distribution pipe 2; when the switching mechanism is in the first state, the distribution pipe feed port 211 is connected to the first discharge port 221; when the switching mechanism is in the second state, the distribution pipe feed port 211 is connected to the second discharge port 231.

[0027] A silo feed port 33 is provided above the silo 3, and a silo discharge port 34 is provided at one end. The silo feed port 33 is provided below the second discharge port 231. A bottom belt is provided at the bottom of the silo 3, and the bottom belt is used to transport the materials in the silo 3. A first detection switch 31 and a second detection switch 32 are provided in the silo 3. The first detection switch 31 is located on a side close to the silo discharge port 34, and the second detection switch 32 is located on a side away from the silo discharge port 34. The first detection switch 31 and the second detection switch 32 are both used to detect the material stacking height in the silo 3.

[0028] The lifting belt 4 is located below the first discharge port 221, and the feeding end of the lifting belt 4 is close to the silo discharge port 34. The material output from the silo discharge port 34 can fall onto the lifting belt 4. A high-position detection switch 41 and a low-position detection switch 42 are provided on the side wall of the lifting belt 4. The distance between the high-position detection switch 41 and the upper surface of the lifting belt 4 is greater than the distance between the low-position detection switch 42 and the upper surface of the lifting belt 4. The high-position detection switch 41 and the low-position detection switch 42 are both used to detect the material stacking height at the feeding end of the lifting belt 4.

[0029] The control unit is electrically connected to the wire storage cabinet 1, the lifting belt 4, the bottom belt and the switching mechanism, and is used to control the start or stop of the wire storage cabinet 1, the lifting belt 4, the bottom belt and the switching of the switching mechanism between the first state and the second state.

[0030] In some embodiments, the feed pipe 2 comprises: The first tube body 21 has a feed inlet 211 for a material distribution pipe at its upper end; The second tube body 22 is disposed below the first tube body 21. The second tube body 22 is connected to the first tube body 21. The lower end of the second tube body 22 is provided with a first discharge port 221. The third tube body 23 is disposed below the first tube body 21 . The third tube body 23 is connected to the first tube body 21 . A second discharge port 231 is disposed at the lower end of the third tube body 23 .

[0031] Furthermore, the switching mechanism includes: A rotating baffle (not shown in the figure) is provided at the upper end of the second tube body 22 or the upper end of the third tube body 23; The driving mechanism (not shown in the figure) is connected to the rotating baffle, and the driving mechanism is used to drive the rotating baffle to rotate between the upper end of the second tube body 22 and the upper end of the third tube body 23 .

[0032] Specifically, the first discharge port 221 at the bottom of the second tube body 22 and the second discharge port 231 at the bottom of the third tube body 23 are respectively arranged above the feed end of the lifting belt 4 and above the feed port 33 of the storage bin, and a rotating baffle and a driving mechanism that can drive the rotating baffle to rotate between the upper ends of the second tube body 22 and the third tube body 23 are provided in the distribution pipe 2. When the material supply is insufficient at the head stage at the beginning of production, the driving mechanism on the distribution pipe 2 drives the rotating baffle to rotate to the upper end of the second tube body 22 to block the upper end of the second tube body 22. At this time, the first tube body 21 is not connected to the second tube body 22, and the third tube body 23 of the distribution pipe 2 is connected to the first tube body 21, and the wire storage cabinet 1 transports materials to the storage bin 3. When the material enters the storage bin 3, the material will first gradually accumulate below the second discharge port 231 until the height of the material reaches the detection area of ​​the first detection switch 31. At this time, the bottom belt begins to move the material along the bottom belt. Figure 1 The material is transported in the Y direction. When the material is transported to the detection area of ​​the second detection switch 32, the detection ends of the first detection switch 31 and the second detection switch 32 will be blocked by the material. When the control unit receives a signal that the first detection switch 31 and the second detection switch 32 have detected the material, the control unit will control the motor driving the bottom belt to stop working, so that the bottom belt stops transporting the material, and the driving mechanism of the control switching mechanism drives the rotating baffle to rotate to the upper end of the third tube body 23 to block the upper end of the third tube body 23. At this time, the first tube body 21 is not connected to the third tube body 23, and the second tube body 22 is connected to the first tube body 21. The material in the wire storage cabinet 1 is transported to the belt of the lifting belt 4 through the first tube body 21 and the second tube body 22 of the distribution pipe 2.

[0033] When the material in the wire storage cabinet 1 has not reached the tailing state, it means that the material in the wire storage cabinet 1 is sufficient, and the wire storage cabinet continues to transport the material to the lifting belt 4. In the process of transporting the material to the lifting belt 4, when the stacking height of the material at the feeding end of the lifting belt 4 is higher than the high-level detection switch 41, the wire storage cabinet 1 stops transporting the material to the lifting belt 4, and when the stacking height of the material at the feeding end of the lifting belt 4 is lower than the low-level detection switch 42, the wire storage cabinet 1 starts to transport the material to the lifting belt 4. When the stacking height at the feeding end of the lifting belt 4 is higher than the high-level detection switch 41 or lower than the low-level detection switch 42 again, the above operation is repeated until the wire storage cabinet tailing detection switch 11 in the wire storage cabinet 1 detects no material.

[0034] When the material in the wire storage cabinet 1 reaches the tailing state, it means that the material in the wire storage cabinet 1 is insufficient, and the bottom belt in the storage bin 3 conveys the material to the lifting belt 4 to prevent material breakage. In the process of conveying the material to the lifting belt 4, when the stacking height of the material at the feeding end of the lifting belt 4 is higher than the high-level detection switch 41, the bottom belt stops conveying the material to the lifting belt 4, and when the stacking height of the material at the feeding end of the lifting belt 4 is lower than the low-level detection switch 42, the bottom belt starts conveying the material to the lifting belt 4. When the stacking height at the feeding end of the lifting belt 4 is higher than the high-level detection switch 41 or lower than the low-level detection switch 42 again, the above operation is repeated until all the materials in the storage bin are conveyed.

[0035] In some embodiments, the lifting belt 4 is provided with multiple rows of rake spikes spaced apart along the conveying direction of the lifting belt 4. During the conveying process of the lifting belt 4, the rake spikes can prevent the material on the lifting belt 4 from falling, so as to facilitate the smooth progress of tobacco production.

[0036] Furthermore, if Figure 2 As shown, the feeder further includes two telescopic baffles, which include a first telescopic baffle 61 and a second telescopic baffle 62. The first telescopic baffle 61 and the second telescopic baffle 62 are arranged at intervals on both sides of the first discharge port 221 along the conveying direction of the lifting belt 4. The first telescopic baffle 61 and the second telescopic baffle 62 are both in the extension direction of the lifting belt 4 (such as Figure 2 The first telescopic baffle 61 is used to control the height of the material when being transported on the upper surface 44 of the lifting belt 4, and the second telescopic baffle 62 is used to prevent the material from slipping out of the lifting belt 4.

[0037] The feeder of the present invention arranges the first telescopic baffle 61 and the second telescopic baffle 62 at intervals on both sides of the first discharge port 221 along the conveying direction of the lifting belt 4, that is, the second telescopic baffle 62 is arranged on the side of the first discharge port 221 close to the storage bin 3, and the first telescopic baffle 61 is arranged on the side of the first discharge port 221 away from the storage bin 3. When the wire storage cabinet 1 conveys materials to the feeding end of the lifting belt 4, the second telescopic baffle 62 can block the materials to prevent the materials from sliding out of the lifting belt 4; when the materials are conveyed on the surface of the lifting belt 4, the first telescopic baffle 61 can control the stacking height of the materials to prevent the subsequent materials from blocking the materials, thereby failing to ensure that the materials are conveyed at a uniform flow rate.

[0038] In some embodiments, Figure 1 and Figure 2 As shown, brackets 45 are provided on both sides along the width direction of the lifting belt 4, and the first telescopic plate 61 and the second telescopic plate 62 are connected to the brackets 45 by bolts. For example, the first telescopic plate 61 and the second telescopic plate 62 are provided with strip holes 63, and the strip holes 63 extend in a direction perpendicular to the upper surface 44 of the lifting belt 4. The bolts pass through the strip holes 63 and are connected to the brackets 45. The design of the strip holes 63 can facilitate the operator to move the first telescopic baffle 61 and the second telescopic baffle 62 closer to or away from the upper surface 44 of the lifting belt 4 in a direction perpendicular to the upper surface 44 of the lifting belt 4 according to actual production needs.

[0039] Furthermore, the feeder also includes a buffer bin 5 , which is arranged between the storage bin 3 and the feeding end of the lifting belt 4 , and the buffer bin 5 is used to receive materials from the storage bin 3 .

[0040] Since the connection between the lifting belt 4 and the storage bin 3 forms a steep angle, i.e., an obtuse angle greater than 90°, the material discharged from the storage bin outlet 34 falls at the steep angle. Due to the gravity of the material, it is not easy to be transported to the next process by the lifting belt 4. Figure 1 As shown, the present application sets a buffer bin 5 between the bin discharge port 34 and the feeding end of the lifting belt 4 .

[0041] Specifically, refer to Figure 1 and Figure 3 A material-dispensing roller 43 is provided above the upper surface of the lifting belt 4. The material-dispensing roller 43 extends along the width direction of the lifting belt 4 and can surround the material-dispensing roller 43. Figure 3 The material-picking roller 43 rotates in the R direction as shown, and a certain distance is spaced between the material-picking roller 43 and the upper surface of the lifting belt 4.

[0042] In some embodiments, the material-moving roller 43 is provided with a plurality of rake nails at intervals around its own circumference. The purpose of providing the rake nails on the material-moving roller 43 is that when the material is tobacco, the rake nails are easy to insert into the tobacco, so that the tobacco can be hung on the rake nails, and the rake nails are used to loosen the tobacco to prevent the tobacco from clumping together, so that the tobacco is evenly located on the lifting belt 4.

[0043] Specifically, the control unit is electrically connected to the wire storage cabinet 1, the lifting belt 4, the bottom belt and the driving mechanism, and is used to control the start or stop of the wire storage cabinet 1, the lifting belt 4, the bottom belt and the driving mechanism.

[0044] In some embodiments, the control unit may be a PLC controller, which is used to control the start or stop of the wire storage cabinet 1, the lifting belt 4 and the bottom belt to transport materials according to the detection results of the first detection switch 31, the second detection switch 32, the low-level detection switch 42, the high-level detection switch 41 and the wire storage cabinet tail material detection switch 11, and to drive the rotating baffle to rotate between the upper end of the second tube body 22 and the upper end of the third tube body 23 through the solenoid valve control driving mechanism.

[0045] Thus, by setting the material distribution pipe 2 in the feeder and setting the control unit on the basis of setting the material distribution pipe 2, the control unit can automatically control the bottom belt, the wire storage cabinet 1 and the action of the switching mechanism in the material distribution pipe 2 according to the material supply situation on the lifting belt 4, so that the materials on the wire storage cabinet 1 or the bottom belt will not be transported to the lifting belt 4 at one time to cause material blockage. It can not only ensure the continuous supply of materials, but also effectively reduce the rolling and friction of materials in the lifting belt 4, thereby reducing the crushing of materials and reducing unnecessary material consumption.

[0046] Based on the same concept, Figure 4 The present invention also provides a feeding control method for the feeder provided in the above embodiment, the feeding control method comprising: Step 101: Control the switching mechanism to operate to the second state, and the wire storage cabinet 1 conveys materials to the storage bin 3 through the material distribution pipe 2. Specifically, when the control unit receives a signal for the start of production, the control unit controls the driving mechanism of the switching mechanism to drive the rotating baffle to rotate to the upper end of the second tube body 22, and the materials in the wire storage cabinet 1 are conveyed to the storage bin 3 through the first tube body 21 and the third tube body 23 of the material distribution pipe 2.

[0047] Step 102: Determine whether the first detection switch 31 and the second detection switch 32 detect materials; If the first detection switch 31 detects material and the second detection switch 32 does not detect material, the bottom belt is controlled to convey material toward the end away from the silo discharge port 34. Specifically, since the second discharge port at the lower end of the third tube body 23 is arranged close to the silo discharge port 34, the material distribution pipe 2 conveys material into the silo 3, and the material will accumulate at the end close to the silo discharge port 34 to the height set by the first detection switch 31. When the control unit receives the signal that the first detection switch 31 detects material, the control unit will control the bottom belt to continue conveying material to the end away from the silo discharge port 34, so as to store the material in the silo 3.

[0048] If the first detection switch 31 detects material and the second detection switch 32 detects material, the bottom belt in the storage bin 3 stops running, and the switching mechanism is controlled to run to the first state, and the wire storage cabinet 1 conveys material to the lifting belt 4 through the material distribution pipe 2. Specifically, when the material reaches the setting height of the first detection switch 31 but does not reach the setting height of the second detection switch 32, the bottom belt continues to convey the material from the storage bin discharge port 34 to the end away from the storage bin discharge port 34, and the material in the storage bin 3 will block the first detection switch 31 and the second detection switch 32. When the control unit receives a signal that both the first detection switch 31 and the second detection switch 32 detect material, the control unit controls the motor driving the bottom belt to stop working, that is, the bottom belt stops conveying material, and controls the driving mechanism of the switching mechanism to drive the rotating baffle to rotate to the upper end of the third tube body 23, and the material in the wire storage cabinet 1 is conveyed to the feeding end of the lifting belt 4 through the first tube body 21 and the second tube body 22 of the material distribution pipe 2.

[0049] Step 103: Determine whether the low-level detection switch 42, the high-level detection switch 41 and the wire storage cabinet tail material detection switch 11 detect material; If the wire storage cabinet tail material detection switch 11 and the low-level detection switch 42 detect materials and the high-level detection switch 41 does not detect materials, the wire storage cabinet 1 is controlled to continue to convey materials to the lifting belt 4, and the lifting belt 4 is running at the same time to convey the materials on the lifting belt 4. Specifically, when the wire storage cabinet tail material detection switch 11 detects that there are materials in the wire storage cabinet 1, it indicates that the materials in the wire storage cabinet 1 are sufficient. At this time, if the low-level detection switch 42 detects materials and the high-level detection switch 41 does not detect materials, it indicates that the materials at the feeding end of the lifting belt 4 are sufficient and not excessive. At this time, the control unit will control the lifting belt 4 to start running, convey the materials at the feeding end of the lifting belt 4 to the next process, and control the wire storage cabinet 1 to continue to convey new materials to the lifting belt 4.

[0050] If the high-level detection switch 41 detects material, the wire storage cabinet 1 is controlled to stop conveying material to the lifting belt 4. Specifically, when the high-level detection switch 41 detects material, it indicates that the material at the feeding end of the lifting belt 4 is excessive. At this time, the control unit controls the wire storage cabinet 1 to stop conveying material to the lifting belt 4, so that only the feeding end of the lifting belt 4 continues to convey material along the X direction, and no new material is added to the feeding end of the lifting belt 4.

[0051] Furthermore, when the low-level detection switch 42 detects no material, it indicates that the material supply at the feeding end of the lifting belt 4 is insufficient. The control unit will control the wire storage cabinet 1 to start conveying materials to the lifting belt 4 until the high-level detection switch 41 detects material again, that is, the material at the feeding end of the lifting belt 4 is oversupplied again. The wire storage cabinet 1 will be controlled to stop working again, and the above steps will be repeated until the wire storage cabinet tail material detection switch 11 detects no material.

[0052] If the wire storage cabinet tail material detection switch 11 does not detect the material, the bottom belt in the storage bin 3 is controlled to transport the material to the lifting belt 4 in the direction of the storage bin discharge port 34 to prevent material breakage. Specifically, when the control unit receives a signal that the wire storage cabinet tail material detection switch 11 does not detect the material, it indicates that the material in the wire storage cabinet 1 has reached the tail material state, that is, the wire storage cabinet 1 has entered the tail material stage. At this time, in order to keep the lifting belt 4 able to continuously and evenly output the material to the outside, the control unit controls the motor driving the bottom belt on the storage bin 3 to reverse, that is, the upper surface of the bottom belt runs toward the storage bin discharge port 34, and the material in the storage bin 3 is transported to the lifting belt 4 through the bottom belt, so that the lifting belt 4 always keeps the material on the next process for output.

[0053] Exemplarily, the first detection switch 31, the second detection switch 32, the low-position detection switch 42, the high-position detection switch 41, and the wire storage cabinet tail material detection switch 11 are all opposing-beam photoelectric switches; When the through-beam photoelectric switch is blocked by the material, the through-beam photoelectric switch sends a signal to the control unit, and the control unit determines that the material has reached the set height of the through-beam photoelectric switch; When the through-beam photoelectric switch is not blocked by the material, the through-beam photoelectric switch will not send a signal to the control unit, and the control unit determines that the material has not reached the set height of the through-beam photoelectric switch.

[0054] In some embodiments, the setting height of each through-beam photoelectric switch can be set according to the type of material.
