Description

TECHNICAL FIELD

[0001] The present application relates to a control system for handling of raw tobacco in a re-drying factory, in particular to a raw tobacco bale layering and unstrapping control method based on a layering and unstrapping mechanism. BACKGROUND

[0002] In the existing control system for re-drying process, the handling of raw tobacco, as the first step of the re-drying process, affects the rhythm and efficiency of the entire re-drying process and is a particularly important process step in the re-drying production. At present, the handling of raw tobacco mainly relies on manual sorting. After the bales of raw tobacco are transported to the site, the packaging bags are manually opened, and the bales of raw tobacco are manually unpacked one by one. The unpacked tobacco leaves are then sent to the conveyor, arranged into a thin layer, and sent to the cutting and unstrapping machine via the conveying equipment. Such a production process requires a large number of manual sorting of raw tobacco bales. Since it relies too much on manual work, the entire production rhythm depends on the working efficiency of the workers. During the curing season, it is difficult to meet the demand for production capacity due to the lack of workers. At the same time, due to the low efficiency and long working time, the energy consumption is large, and the mechanical wear is serious, which further limits the automation level of the factory production. Since the raw tobacco is dry, a large amount of dust is generated during manual layering, which makes the working environment very poor and difficult to protect the health of workers. SUMMARY

[0003] The technical problem to be solved by the present application is to provide a raw tobacco bale layering and unstrapping control method based on a layering and unstrapping mechanism, which overcomes the shortcomings of the prior art. According to the structural characteristics of the raw tobacco bale and the functional characteristics of the layering and unstrapping device, a standard control interface and logic control function based on Step7 are designed, and a control method based on the above raw tobacco bale layering and unstrapping control system is provided.

[0004] To solve the above technical problems, the present application provides a raw tobacco bale layering and unstrapping control method based on a layering and unstrapping mechanism, characterized by comprising the following steps:

[0005] Step 1: position initialization. After the production starts, the lifting conveyor is lifted to the top of the lower half of the layering and unstrapping mechanism, i.e. Figure 7 the position where the lifting conveyor is lifted to the position, the first layering device upper fork and the second layering device upper fork are lifted to two-thirds of the upper half of the layering and unstrapping mechanism, i.e. Figure 7 the position where the layering device is lifted to the position; the first layering device upper fork and the second layering device upper fork are opened to the side of the layering and unstrapping mechanism, i.e. Figure 7 the position where the layering device upper fork 1 and the layering device upper fork 2 are opened to the position; the first layering device lower fork and the second layering device lower fork are opened to the side of the layering and unstrapping mechanism, i.e. Figure 7The lower fork 1 of the middle tiering device and the lower fork 2 of the tiering device are in the opened position;

[0006] After selecting the mode and initializing the position, you can choose between two modes: layered cigarette packs and non-layered cigarette packs.

[0007] a. Non-layered: When the mode is selected as non-layered, the layering device automatically performs position initialization, the horizontal conveyor runs continuously, and directly delivers the incoming tobacco packages;

[0008] b. Layering: A grating sensor is installed at the inlet of the layering machine. As the tobacco pack passes through the grating, the height h of the tobacco pack is obtained by collecting the grating data, and the system automatically sets the number of layers N. Depending on the actual situation and the height of the tobacco pack, it is generally 3 or 4 layers on average.

[0009] Step 2: Packet loading, horizontal conveyor starts running, lifting conveyor detects cigarette packs, horizontal conveyor belt stops running, other equipment remains in the previous state;

[0010] Step 3: Unloading the package. After the package is loaded, the lifting conveyor descends at a speed of 0.05-0.3 m / s to one-third of the lower half of the layer unloading mechanism, i.e., the attached layer. Figure 7 The middle position 1 of the central lifting conveyor; the tiered device lifting platform drives the first and second tiered device upper forks, descending at a speed of 40-60HZ to one-third of the upper half of the tiered unloading mechanism, and then attaches... Figure 7 The intermediate stratification device descends to the deceleration position, reducing its speed to 10-20 Hz, and descends to the bottom of the upper half of the stratification mechanism, i.e., the attached... Figure 7 When the middle stratification device descends to its designated position, other equipment remains in its previous state.

[0011] Step 4: Inserting the bag. After the bag is unloaded, the upper fork of the first layering device and the upper fork of the second layering device are inserted into the middle position of the layering and unloading mechanism, i.e., attached... Figure 7 The positions of the middle layer upper fork 1 and the layer upper fork 2 are in place; the lower fork of the first layering device and the lower fork of the second layering device are inserted into the middle position of the layering unbundling mechanism, i.e., attached. Figure 7 When the middle layer lower fork 1 and the middle layer lower fork 2 are in position, other equipment remains in the previous state;

[0012] Step 5: After the pack is inserted into the layers, the lifting mechanism of the layering device moves the upper fork of the first layering device, the upper fork of the second layering device, and the pack located above the upper fork of the layering device to rise at a speed of 40-60 Hz to the middle of the upper half of the layering and unpacking mechanism, and then attaches... Figure 7 The middle layer device rises to the deceleration position, the speed decreases to 10-20 Hz, and rises to two-thirds of the upper half of the layering mechanism, i.e., the attached layer. Figure 7 When the middle layer device rises to its designated position, other equipment remains in its previous state.

[0013] Step 6: Layering, after the completion of the layered dismounting, the lifting conveyor is lifted to the top of the lower half of the layered dismounting mechanism at a speed of 0.05-0.3 m / s, i.e. the position shown in Figure 8. Figure 7 The lifting conveyor is lifted to the position shown in Figure 8, and other devices remain in the previous state;

[0014] Step 7: Smoking, after the completion of the layering, the horizontal conveyor sends the first layer of cigarette packs out, and the horizontal conveyor stops running after the lifting conveyor detects no cigarette packs, and other devices remain in the previous state;

[0015] Step 8: Pack, after the completion of the smoking, the layered device lifter drives the first layered device upper prong and the second layered device upper prong and the cigarette packs located on the upper part of the layered device upper prong to descend to one-third of the upper half of the layered dismounting mechanism at a speed of 40-60 HZ, i.e. the position shown in Figure 9. Figure 7 The speed is reduced to 10-20 HZ and the layered device is lowered to the bottom of the upper half of the layered dismounting mechanism, i.e. the position shown in Figure 10. Figure 7 The layered device is lowered to the position shown in Figure 10, and other devices remain in the previous state;

[0016] Step 9: In position, after the completion of the pack, the first layered device upper prong and the second layered device upper prong are opened to the side of the layered dismounting mechanism, i.e. the position shown in Figure 11. Figure 7 The first layered device upper prong 1 and the layered device upper prong 2 are opened to the position shown in Figure 11; the first layered device lower prong and the second layered device lower prong are opened to the side of the layered dismounting mechanism, i.e. the position shown in Figure 12. Figure 7 The first layered device lower prong 1 and the layered device lower prong 2 are opened to the position shown in Figure 12, and the cigarette packs fall onto the horizontal conveyor, and other devices remain in the previous state; at this time, the number of divided layers n = n+1, and it is judged whether the number of divided layers n is less than the set number of divided layers N.

[0017] The demounting mechanism in the application is divided into an upper half and a lower half at the installation plane of the conveying belt. According to the sensor detection state of the storage cabinet, the application defines a unified data interface, which is as follows:

A method for controlling the layering and unlayering of cigarette packets based on a layering and unlayering mechanism, characterized by: The method comprises the following steps: Step 1: position initialization, after production starts, the lifting conveyor rises to the top of the lower half of the layered unwrapping mechanism, the layered device lifting machine drives the first layered device upper prong and the second layered device upper prong to rise to two-thirds of the upper half of the layered unwrapping mechanism, the first layered device upper prong and the second layered device upper prong open to the side of the layered unwrapping mechanism, and the first layered device lower prong and the second layered device lower prong open to the side of the layered unwrapping mechanism; Mode selection, after position initialization, select two modes of cigarette packet layering and non-layering: a. Non-layering: when the mode selection is non-layering, the layered device automatically performs position initialization, and the horizontal conveyor continuously runs to directly send the incoming cigarette packets out; b. Layering: a grating sensor is installed at the entrance of the layered unwrapping mechanism, the cigarette packet passes through the grating, the height h of the cigarette packet is obtained by collecting grating data, and the system automatically sets the number of layers N; Step 2: packet feeding, the horizontal conveyor runs, the lifting conveyor detects the cigarette packet, the horizontal conveyor stops running, and other devices remain in the previous state; Step 3: packet dropping, after the packet feeding is completed, the lifting conveyor descends to one-third of the lower half of the layered unwrapping mechanism, the layered device lifting machine drives the first layered device upper prong and the second layered device upper prong to descend to the bottom of the upper half of the layered unwrapping mechanism, and other devices remain in the previous state; Step 4: packet insertion, after the packet dropping is completed, the first layered device upper prong and the second layered device upper prong are inserted into the middle position of the layered unwrapping mechanism, the first layered device lower prong and the second layered device lower prong are inserted into the middle position of the layered unwrapping mechanism, and other devices remain in the previous state; Step 5: layered unwrapping, after the packet insertion is completed, the layered device lifting machine drives the first layered device upper prong, the second layered device upper prong, and the cigarette packet located on the upper part of the layered device upper prong to rise to the middle of the upper half of the layered unwrapping mechanism, then the speed is lowered to rise to two-thirds of the upper half of the layered unwrapping mechanism, and other devices remain in the previous state; Step 6: layer lifting, after the layered unwrapping is completed, the lifting conveyor rises to the top of the lower half of the layered unwrapping mechanism, and other devices remain in the previous state; Step 7: cigarette output, after the layer lifting is completed, the horizontal conveyor sends out the first layer of cigarette packets until the lifting conveyor detects no cigarette packet, then the horizontal conveyor stops running, and other devices remain in the previous state; Step 8: packet placement, after the cigarette output is completed, the layered device lifting machine drives the first layered device upper prong, the second layered device upper prong, and the cigarette packet located on the upper part of the layered device upper prong to descend to one-third of the upper half of the layered unwrapping mechanism, then the speed is lowered to descend to the bottom of the upper half of the layered unwrapping mechanism, and other devices remain in the previous state; Step 9, in place, after the completion of the package, the first layer device upper prong and the second layer device upper prong open to the side of the layering handle releasing mechanism, the first layer device lower prong and the second layer device lower prong open to the side of the layering handle releasing mechanism, the cigarette package falls onto the horizontal conveyor, and other equipment remains in the previous state; at this time, the number of layers n = n+1, and it is determined whether the number of layers n is less than the set number of layers N; if the number of layers n is less than the set number of layers N, steps 3 to 9 are repeated, and when the number of layers n is equal to the set number of layers N, step 1 is executed, and the number of layers n is cleared.
