Background Art

[0002] The tobacco rod forming in the cigarette machine is usually done by using a rolling mechanism to wrap the tobacco bundle from the supply system in a cigarette paper belt, apply glue, and then use a soldering iron to dry it to form a continuous tobacco rod. The continuous tobacco rod is then transported to the cutter disc and cut by the cutter disc to form a double-length cigarette with uniform length; the movement of the tobacco rod is provided by the cloth belt of the cloth belt wheel. In existing cigarette machine equipment, the cutter disc, cloth belt wheel, paper roller and other components are basically driven by mechanical synchronous belts.

[0022] The embodiments of the present application are written in a progressive manner.

[0023] The embodiment of the present application provides a positionable cutting cigarette making machine device capable of measuring tobacco rod markings, comprising: a frame, a cloth belt wheel, a cloth belt, a cigarette gun, a soldering iron device, a color mark sensor device, a cigarette rod maker, a paper belt roller, a paper belt pre-printed with equally spaced visible markings, a splitting knife device, a glue coating device, a microwave density detection device, a knife disc and a servo control system; the servo control system comprises a servo motor and a servo controller system; the knife disc, the cloth belt wheel and the paper belt roller are independently connected to a servo motor; the tobacco bundle and the paper belt with visible markings are formed by the cigarette gun and dried by the soldering iron to form tobacco rods with equally spaced visible markings; the color mark sensor device has There is a color mark sensor, which is provided at the outlet end of the cigarette gun between the soldering iron device and the cigarette rod maker, and the color mark sensor is located above the cigarette rod. The color mark sensor is connected to the servo controller system, and the color mark sensor is used to identify the visual mark on the cigarette rod and output pulse data to the servo controller system; the microwave density detection device has a cigarette rod detection channel for density detection of the cigarette rod; the servo controller system controls the speed of the servo motors of the paper tape roller and the cloth tape wheel based on the accumulated error value obtained from the color mark sensor pulse data, so that the phase of a certain visual mark on the cigarette rod is adjusted to be consistent with the phase of the cutter on the knife disc.

[0024] In the above scheme, the mechanical synchronous belt drive of the knife disc, cloth belt wheel and paper belt roller in the existing cigarette machine is improved and designed to be driven by an independent servo motor, which improves the speed of the cigarette paper feeding and the control of the synchronous adjustment phase of the cigarette paper; the cigarette paper belt with equidistantly distributed visual marks is wrapped with tobacco and driven by the cloth belt into the cigarette gun for forming, and the glue coating device applies glue on the cigarette paper, and the glue is dried by the soldering iron to form a cigarette rod; at the outlet of the cigarette gun, the color mark sensor continuously identifies the visual mark on the cigarette rod, and the pulse signal generated by the color mark sensor is driven by the servo motor The system receives and obtains continuous measurement of the cumulative error of the spacing between the visual marks on the cigarette rods. The cumulative error value will be used for feedback control of the rotation speed of the cloth belt wheel and the paper supply roller, and adjust the running speed of the cigarette rod in the cloth belt, so that the phase of a certain visual mark on the cigarette rod is adjusted to be consistent with the phase of the cutter on the knife disc. After completing the relative positioning of the visual mark on the cigarette rod to the knife disc cutter, the tobacco rod maker sends the cigarette rod into the detection hole of the microwave density monitor to detect the density of the cigarette rod and then sends it to the knife disc for cutting. The position after cutting will divide the visual mark on the cigarette rod into two halves, thus realizing continuous positioning and cutting of the cigarette rod.

[0025] Furthermore, the synchronous phase control of the cigarette making machine equipment includes: adding a paper supply virtual axis representing the paper supply system, and the paper supply virtual axis follows the virtual main axis of the cigarette making machine equipment for position synchronization; the cloth belt wheel and the paper belt roller follow the paper supply virtual axis for synchronization.

[0026] The synchronous phase control relationship of cigarette making machine equipment specifically includes: The electric servo motor of the cutter disc drives the cutter disc to cut the tobacco rod, and synchronizes the position of the cutter disc with the virtual main axis of the cigarette making machine equipment, and the synchronization phase is offset1=0; The paper feeding virtual axis of the cigarette making machine equipment is synchronized with the virtual main axis, and its synchronization phase is offset2. The synchronization phase value is set and adjusted by the servo controller system; The cloth belt wheel servo motor drives the cloth belt wheel to synchronize its speed with the paper feeding virtual axis, and its synchronization phase is offset3=0; The paper roller servo motor drives the paper tape roller to synchronize its speed with the paper feed virtual axis, and its synchronization limit is offset4=0.

[0027] The cutter of the cutter disc is at zero position (i.e., the position when the cutter cuts the tobacco strip), and the center of the light spot of the color mark sensor is located at a position where the distance from the cutter disc is set to an integer multiple of the visual mark spacing. Preferably, the color mark sensor is arranged at the node where the tobacco strip has just completed wrapping and forming for mark detection. Here, after the cigarette paper wraps the tobacco shreds, a stable cylindrical tobacco strip is formed at the outlet on the left side of the cigarette gun, which reduces the adverse effects of uncertainty factors such as tensile deformation and slippage of the cigarette paper band on the positioning mark detection accuracy. At this time, the tobacco strip has not yet run to the cutter disc to enter the cutting position. Here, the control program completes the quick adjustment of the tobacco strip cut position on the tobacco strip to align with the target position, avoiding the problem that the adjustment range of the tobacco strip will be limited after the cutter disc enters the cutting position. At the same time, it can shorten the adjustment time, reduce the waste of raw materials, and improve the working efficiency of the equipment. Therefore, it is best to arrange the color mark sensor here.

[0028] Each time the cigarette making machine is started and before the cigarette rod making machine makes the cigarette rod, the phase of the visual mark on the cigarette rod can be monitored online based on the color mark sensor and dynamically compared with the position difference of the cutter on the cutter disc. The servo system controls the speed of the servo motor of the cloth belt wheel to adjust the phase of a visual mark on the cigarette rod to be consistent with the phase of the cutter on the cutter disc.

[0029] Furthermore, the soldering iron device includes a soldering iron stand, a soldering iron and a telescopic driving member; the soldering iron is arranged on the soldering iron stand, and a soldering iron hinge is provided on the soldering iron stand, and the soldering iron hinge is rotatably connected to the frame; the frame and the soldering iron stand are both provided with a telescopic driving member hinge, and the two ends of the telescopic driving member are respectively arranged on the telescopic driving member hinge. The telescopic driving member is a cylinder, an oil cylinder or an electric push cylinder. The telescopic driving member of the present application is a cylinder, and the telescopic driving member hinge includes a cylinder hinge 1 and a cylinder hinge 2. Further, the color mark sensor device is arranged on the soldering iron stand and follows the movement of the telescopic driving member. Specifically, the color mark sensor device includes a color mark sensor stand and a color mark sensor, and the color mark sensor is arranged on the color mark sensor stand, and the color mark sensor stand is arranged and connected to the soldering iron stand. A heat insulation board is arranged between the color mark sensor stand and the soldering iron stand.

[0030] See also Figures 1 to 8The cigarette making machine equipment of the present application includes the following parts: 1. frame, 2. cloth belt wheel, 3. cloth belt, 4. tensioning wheel, 5. cigarette gun, 6. soldering iron, 7. soldering iron bracket, 8. cylinder, 9. heat insulation board, 10. color mark sensor bracket, 11. color mark sensor, 12. strip making machine, 13. marked cigarette strip, 13.1. target position for cutting on the cigarette strip, 14. microwave detection device, 15. microwave device detection hole, 16. knife disc, 17. knife disc cutter, 18. cylinder hinge 1, 19. soldering iron bracket hinge, 20. cylinder hinge 2.

[0031] The present application also provides a positioning adjustment method capable of measuring a cigarette rod mark, comprising the above-mentioned cigarette making machine device, comprising the following steps: Start and operate cigarette making machine equipment; The color mark sensor samples and obtains the visual mark data on the cigarette rod; Based on the sampling data of the color mark sensor, it is calculated and analyzed to determine whether there is a cumulative error between the color marks on the cigarette rod. If there is a cumulative error, a corresponding speed compensation value is given according to the average error between the color marks; It is determined whether the tobacco rod cut position is at the target position. If the tobacco rod cut position is not at the target position, the servo controller system adjusts the synchronous phase of the tobacco rod until the tobacco rod cut position is stabilized at the target position.

[0032] It should be noted that there are measurable tobacco rod marks on the tobacco rod. The distance between the cut section of the tobacco rod and the visual mark is not at the target position. The servo controller system adjusts the synchronous phase of the tobacco rod until the tobacco rod cut position is aligned with the target position (the alignment of the tobacco rod cut position with the target position refers to the center line position between two adjacent visual marks of the tobacco rod), see Figure 8 , the target position of the cut on the tobacco rod with the mark; whether the tobacco rod cut position is aligned with the target position can be ensured by the synchronous phase adjustment in the above manner. After the tobacco rod cut position is aligned with the target position, the control program of the cigarette making machine equipment switches to the automatic operation mode, the rod cutter works, and the tobacco rod with the visual mark passes through the microwave detection device and is cut by the knife disc. At the same time, manual sampling can be further used to determine whether the tobacco rod cut position is aligned with the target position.

[0033] Furthermore, the method of calculating and analyzing the sampling data of the color mark sensor to determine whether there is a cumulative error between the color marks on the cigarette rod, and if there is a cumulative error, giving a corresponding speed compensation value according to the average error between the color marks, specifically includes: The color mark sensor identifies multiple visual marks on the cigarette rod online and outputs pulse data to the servo controller system. The servo controller system calculates the actual distance between the multiple visual marks based on the pulse data and the rotation speed information of the cloth tape wheel, and compares it with the theoretical distance between the same number of visual marks to obtain the cumulative error between the multiple visual marks; the cumulative error value is used for feedback control of the rotation speed of the cloth tape wheel and the paper feed roller to adjust the running speed of the cigarette rod in the cloth tape, so that the center of the visual mark on the cigarette rod is aligned with the center of the tight end position of the cigarette.

[0034] It must be pointed out that in the process of evaluating whether the incision position of the cigarette rod is accurately aligned with the predetermined target position, it is also possible to further randomly sample the cigarettes produced by the device of the present invention and use a vernier caliper to accurately measure the cutting position size of the sampled cigarettes to verify whether it is within the tolerance range set by the process specification. In other words, the incision position of the cigarette rod should be located at the center line position of two adjacent visual marks. In addition, the use of other means such as image recognition detection technology is also an effective way to verify the alignment.

[0035] Through the above adjustment method, after the cigarette making machine equipment starts running, the color mark sensor starts sampling and transmits the signal to the servo controller. After receiving the signal, the servo controller starts calculating the distance between the color marks and determines whether there is an error between the color marks on the cigarette rod. If there is a cumulative error, a corresponding speed compensation value is given according to the average error between the color marks. The speed compensation value is used to eliminate the cumulative error between the color marks, so that the incision position of the cigarette rod is stabilized at a certain position; then the servo system will determine whether the incision position of the cigarette rod after eliminating the cumulative error is at the target position. If it is not at the target position, the servo system will automatically adjust the synchronization phase of the cigarette rod until the incision position of the cigarette rod is stabilized at the target position, that is, the phase of a certain visual mark on the cigarette rod is adjusted to be consistent with the phase of the cutter on the knife disc; according to the positioning adjustment method of the present application, the cigarette making machine equipment can adjust the cigarette rod with a visual mark to be periodically cut to a fixed position at different speeds (acceleration, deceleration, uniform speed, etc.).

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
