Description

Technical Field

[0001] This utility model relates to the field of material buffering and conveying technology, and in particular to a T-type diversion and merging buffering and conveying system. Background Technology

[0002] In the cigarette packaging production process, the rod-shaped material buffer conveyor is a crucial component of the cigarette-making and packaging production line. Its main functions are twofold: first, conveying the rod-shaped materials between the cigarette-making machine and the packaging machine; and second, matching upstream and downstream production capacity. When the upstream cigarette-making machine and the downstream packaging machine experience a mismatch in production speed or a short-term shutdown due to a malfunction, the rod-shaped material buffer conveyor can collect or release the rod-shaped materials in real time, thus achieving upstream and downstream production capacity matching, ensuring normal production line operation, improving equipment efficiency, and reducing material waste.

[0003] Patent application CN 201810984732.7 discloses a device for conveying and storing rod-shaped materials. In this material buffering and conveying device, the material provided by the upstream rod forming equipment is first lifted to a higher conveying channel. A cylindrical storage device is positioned between the rod forming equipment and the downstream packaging machine. To save space, the cylindrical storage device is located below the higher conveying channel. The material diversion device in this device is F-shaped. Figure 1 As shown, in this prior art material diversion device, the material inlet 100 for connecting to the high-level conveying channel and the conveying port 200 for connecting to the cylindrical storage device are located on the upper and lower sides in the vertical direction, respectively. When the upstream bar forming equipment stops, the cylindrical storage device needs to supply material to the downstream packaging machine. When the material is discharged to the left from the conveying port 200 of the cylindrical storage device, in order to keep the inside of the diversion device always full of material (if there are gaps in the conveying channel, the conveyed bar material will become disordered, and the material cannot be kept neat and orderly, so the downstream packaging machine cannot directly package), the material conveyed to the left from the conveying port 200 will squeeze the material at the bottom of the vertical discharge section 300 of the diversion device, thereby damaging the bar material and causing a decrease in the quality of the conveyed bar material. Therefore, it is necessary to improve the design of the existing material buffer conveying device to solve the impact of the existing material diversion structure on the quality of the conveyed bar material. Utility Model Content

[0011] In some embodiments, the height values of the conveying channels of the T-shaped diverging, converging and buffering conveying system are consistent. The height value of the conveying channel of the T-shaped diverging, converging and buffering conveying system is defined as the dimension of the conveying channel in the direction perpendicular to the conveying direction and perpendicular to the length direction of the conveyed rod-shaped materials.

[0012] In some embodiments, the T-shaped diverging, converging and buffering conveying system further comprises:

[0013] A first servo motor is installed at the inlet horizontal conveying channel and used to drive the movement of the first conveying surface.

[0014] A second servo motor is installed at the vertical lifting conveying channel and used to drive the movement of the second conveying surface.

[0019] The seventh servo motor is installed in the converging conveying channel and is used to drive the seventh conveying surface to move.

[0020] In some embodiments, the T-shaped split-converging buffer conveying system further comprises a first material level detector installed at the inlet of the vertical lifting conveying channel and used to detect the thickness value of the rod-shaped material layer at the inlet of the vertical lifting conveying channel in real time.

[0021] In some embodiments, the T-shaped split-converging buffer conveying system further comprises a second material level detector installed at the top of the inner side of the converging conveying channel and used to detect the thickness value of the rod-shaped material layer conveyed by the converging conveying channel in real time.

[0022] In some embodiments, the T-shaped split-converging buffer conveying system further comprises a third material level detector installed at the top of the inner side of the material bin of the T-shaped split device and used to detect the thickness value of the rod-shaped material layer in the material bin of the T-shaped split device in real time.

[0028] The T-type diversion and merging buffer conveying system provided by this utility model first conveys the rod-shaped material produced by the upstream equipment through the inlet horizontal conveying channel, and then lifts it through the vertical lifting conveying channel before directly connecting it to the T-type diversion device. The right interface of the T-type diversion device is connected to the buffer via a bidirectional conveying buffer conveying channel, and the left interface is connected to the downstream packaging machine via a merging conveying channel. The conveying planes of the left and right interfaces of the T-type diversion device are on the same horizontal plane. This improved design eliminates the need for the high-level conveying channel in the prior art before the material is diverted and merged into the buffer. Therefore, the vertical feeding section (e.g., ...) is eliminated in the diversion device. Figure 1 In the vertical feeding section 300, when the upstream rod-shaped material production equipment stops, the material in the vertical lifting conveyor channel is in a static state. The buffer feeder inputs material to the right interface of the T-shaped diverter through the buffer conveyor channel. After passing horizontally through the T-shaped diverter, the material is output to the downstream packaging machine from the left interface of the T-shaped diverter. During this process, the material input to the T-shaped diverter through the buffer conveyor channel and the material in the vertical lifting conveyor channel are in different horizontal planes, which will not cause compression to the material in the vertical lifting conveyor channel. Therefore, it can solve the problems existing in the prior art and improve the quality of the conveyed rod-shaped material. Attached Figure Description

[0086] When ( V h ≤ 10 / stick / min) and ( V l ≤ 10 / stick / min) and ( R 2≥ S f ), it is a full-stop shunt compensation operation condition, under which the rod-shaped material production equipment and the packaging machine are both in a stopped state, and since R 2≥ Sf In order to prevent the silo from being blocked, the T-shaped shunt device 3 at this time shunts a small amount of rod-shaped objects in the channel to the buffer 5 for storage;

[0087] When (V V h ≤10 / branch / minute) and (V V l ≤10 / branch / minute) and (V R 2≤ S h When the running condition is full stop compensation, the rod-shaped material production equipment and the packaging machine are both in a stopped state, and since R 2≤ S h In order to prevent the silo from being emptied, the buffer 5 outputs a small amount of material to the T-shaped shunt device 3 at this time.

[0088] Preferably, after determining the running condition of the current system based on the preset condition judgment rule, the method for controlling the running speed of the sixth servo motor M06 by the sixth driving device U06 according to the running condition of the current system is:

[0089] When the running condition of the current system is the full-in shunt running condition, the main controller 18 calculates the fourth running speed value according to the fourth formula, and the fourth formula is:

[0090] V 4=( V l + R 2)× k 4

[0091] When the running condition of the current system is the full-out shunt running condition, the main controller 18 calculates the fifth running speed value according to the fifth formula, and the fifth formula is:

[0092] V 5=( V h + R 2)× k 4

[0093] When the running condition of the current system is the high-speed shunt differential compensation running condition, the main controller 18 calculates the sixth running speed value according to the sixth formula, and the sixth formula is:

[0094] V 6=( V l - V h + R 2)× k 4

[0095] When the current system operating condition is the high-speed confluence difference compensation operating condition, the main controller 18 calculates a seventh operating speed value according to a seventh formula, which is:

[0096] V 7=( V h – V l + R 2)× k 4

[0097] When the current system operating condition is the low-speed split-flow difference compensation operating condition, the main controller 18 calculates an eighth operating speed value according to an eighth formula, which is:

[0098] V 8=( S i + R 2)× k 4

[0099] When the current system operating condition is the low-speed confluence difference compensation operating condition, the main controller 18 calculates a ninth operating speed value according to a ninth formula, which is:

[0100] V 9=( S i + R 2)× k 4

[0101] When the current system operating condition is the full-stop split-flow compensation operating condition, the main controller 18 calculates a tenth operating speed value according to a tenth formula, which is:

[0102] V 10 = R 2× k 4

[0103] When the current system operating condition is the full-stop confluence compensation operating condition, the main controller 18 calculates an eleventh operating speed value according to an eleventh formula, which is:

[0104] V 11 = R 2× k 4

[0105] In the above fourth / fifth / sixth / seventh / eighth / ninth / tenth / eleventh formulas, V 4 to V 11 are the fourth operating speed value to the eleventh operating speed value calculated under various conditions, respectively, R2 is the current detection value of the third material level detector 11, k 4 is the fourth preset adjustment correction coefficient; wherein, when the main controller 18 calculates the fourth / sixth / eighth / tenth running speed value, the running speed value of the sixth servo motor M06 is controlled by the sixth driving device U06 to be the current calculated fourth / sixth / eighth / tenth running speed value, and the sixth servo motor M06 is controlled to rotate in the positive direction so that the buffer 5 buffers the material inward; when the main controller 18 calculates the fifth / seventh / ninth / eleventh running speed value, the running speed value of the sixth servo motor M06 is controlled by the sixth driving device U06 to be the current calculated fifth / seventh / ninth / eleventh running speed value, and the sixth servo motor M06 is controlled to rotate in the reverse direction so that the buffer 5 transports the material outward; the main controller 18 controls the sixth servo motor M06 at the same time, and also controls the fifth servo motor M05 to follow the sixth servo motor M06 to move synchronously through the fifth driving device U05.

[0106] It is worth noting that in the above first formula to eleventh formula, all physical parameters adopt the standard unit set in advance, and only the numerical value of each physical quantity (without unit) is taken for calculation. Among them, the standard unit set in advance of each physical parameter is: the unit of running speed is "branch / minute", the unit of rod-shaped material diameter is "mm" (millimeter), the unit of conveying channel height is "mm" (millimeter), the unit of rod-shaped material layer thickness value is "mV" (millivolt), S f and S h the unit of is "mV" (millivolt), S i the unit of is "branch / minute".

[0107] Further, when the current working condition is any one of the split flow working condition, the main controller 18 controls the electronic gear ratio of the third servo motor M03 to be 1:1.2, controls the electronic gear ratio of the fourth servo motor M04 to be 1:1, and the third servo motor M03 runs in overdrive. When the current working condition is any one of the flow merging working condition, the main controller 18 controls the electronic gear ratio of the third servo motor M03 to be 1:1, controls the electronic gear ratio of the fourth servo motor M04 to be 1:1.2, and the fourth servo motor M04 runs in overdrive.

[0108] In other preferred embodiments, as shown in Figure 2 the T-shaped split-flow and flow-merging buffer conveying system further comprises a buffer amount detector 13 installed in the buffer 5, which is used to detect the current buffer amount of the buffer 5 in real time and feed back the current buffer amount to the main controller 18; the main controller 18 controls the upstream rod-shaped material production equipment or the downstream packaging machine according to the current buffer amount to further improve the adaptive matching degree of the T-shaped split-flow and flow-merging buffer conveying system with the upstream and downstream production rhythm.

[0109] The flexible beat control of the upstream rod material production equipment is that: when the second driving device U02 starts the second servo motor M02 (i.e., the lifting operation control unit 14 enters the self-starting state), the main control unit 18 judges whether the buffer 5 is full according to the current buffer amount; if yes, a running prohibition prompt signal is sent to the upstream rod material production equipment; otherwise, a running permission prompt signal is sent to the upstream rod material production equipment, and the current buffer amount is continuously monitored to see whether it reaches the preset first buffer amount, and when the current buffer amount reaches the preset first buffer amount, a speed reduction prompt signal is sent to the upstream rod material production equipment.

[0110] The flexible beat control of the downstream packaging machine is that: when the sixth driving device U06 starts the sixth servo motor M06 (i.e., the buffer operation control unit 15 enters the self-starting state), the main control unit 18 judges whether the buffer 5 is empty according to the current buffer amount; if yes, a running prohibition prompt signal is sent to the downstream packaging machine; otherwise, a running permission prompt signal is sent to the downstream packaging machine, and the current buffer amount is continuously monitored to see whether it reaches the preset second buffer amount, and when the current buffer amount reaches the preset second buffer amount, a speed reduction prompt signal is sent to the downstream packaging machine.

[0111] Preferably, the buffer amount detector 13 selects an incremental absolute value encoder to detect the rotation range of the buffer 5 in real time, and the real-time range value of the buffer 5 is fed back to the main control unit 18 through the EtherCAT bus communication mode, and the main control unit 18 converts the real-time range value of the buffer 5 into a number through a preset program as the current buffer amount.

[0112] The working process of the T-shaped branch and convergence buffer conveying system provided by the utility model is as follows:

[0113] Step 1, system initialization: the main control unit 18 starts the buffer start when the system is powered on for the first time, executes the related program according to the code structure, and automatically runs the window application program, and each servo driver enters the ready state.

[0114] Step 2, system self-diagnosis: check whether the communication of each substation is normal, check whether the device hardware is ready, and accurately locate the fault point of the device through the self-diagnosis function to give the corresponding processing method.

[0115] Step 3, system operation mode selection: divided into automatic mode and manual mode.

[0116] Among them, the automatic mode is applied to the normal production process of the winding wire, and the starting priority of the buffer operation control unit 15 is the highest in the automatic mode, and the starting of the lifting operation control unit 14 is the second. The manual mode is applied to the equipment debugging and maintenance, and single mechanism point operation and large component linkage can be realized. The starting priority of the buffer operation control unit 15 is the highest in the manual mode, and the starting of the lifting operation control unit 14 is the second.

[0117] Step 4, receiving the start button signal

[0118] Among them, the stop button has the highest priority, and in any state, the device stops running and enters the stop state by pressing the stop button; the second is the reset button, and the device should be reset first in the stop state. The state is reset, the start button is triggered after the reset is successful, and the device enters the start standby mode.

[0119] Step 5, system running: if the start button signal in the automatic mode is received in the previous step, the system enters the automatic running program, and if the start button signal in the manual mode is received in the previous step, the system enters the single machine manual running program. After entering the automatic running program, the main controller 18 calculates the above-mentioned various running speed values and controls the motors, while realizing the flexible beat control of the upstream cigarette machine and the flexible beat control process of the downstream packaging machine.

[0120] In the self-diagnosis initial stage of step 2 and the real-time running process of step 5, if the system monitors an exception or a fault, the system automatically enters the stop state, and after the reset button is reset successfully, the subsequent process can be entered.

[0121] In addition, the system also sets an emergency mode, mainly including a device emergency stop operation mode and a buffer limit position emergency mode. The emergency stop operation function is mainly used for emergency stop of the device during running or debugging. The buffer limit position emergency function is mainly used for protecting the buffer, and when the running position of the buffer is out of limit, the emergency function is triggered to stop the device running.

[0122] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
