[0025] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0026] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or apparatuses.

[0027] The cigarette pack production process includes assembling inner packs and assembling outer packs. After the inner pack production equipment assembles the inner packs, it transmits the assembled inner packs to the outer pack production equipment through a conveyor belt. After the outer pack production equipment receives the inner packs through a conveyor belt, it processes the inner packs to obtain the outer packs of the cigarette packs.

[0028] However, the operating speed of the outsourced production equipment and the conveyor belt transportation speed will affect the output of the outsourced production equipment. At present, the transmission belt motor is manually controlled to manually adjust the conveyor belt transportation speed so that the conveyor belt transportation speed matches the operating speed of the outsourced production equipment.

[0029] In terms of production efficiency, a belt speed that is too slow may cause a bottleneck in the production process of the outsourced production equipment, and the cigarette packs cannot be delivered to the box molds of the subsequent equipment (such as the fifth wheel) in time, causing blockages in the subsequent equipment (such as the fifth wheel). If the belt speed is too fast, when the outsourced production equipment has slowed down, the belt may still run fast, causing the subsequent cigarette packs to collide with the previous cigarette packs, causing them to be skewed and block the subsequent equipment (such as the fifth wheel), which also affects the continuity of production and reduces efficiency. In terms of product quality, if the belt speed does not match the speed of the packaging machine, the product may be squeezed or collided during the belt conveying process, damaging the product appearance and causing defects. How to quickly and accurately realize automated conveyor belt control has become an urgent problem to be solved.

[0030] Figure 1 The present invention provides a schematic structural diagram of a cigarette pack production device according to an embodiment of the present invention, which includes an inner pack production device 1, an outer pack production device 2 and a conveyor belt 3. The inner pack production device 1 conveys the produced cigarette pack inner packs to the outer pack production device 2 via the conveyor belt 3. The outer pack production device 2 processes the cigarette pack inner packs and assembles the cigarette pack outer packs.

[0031] Figure 2 The present invention provides a flow chart of a conveyor belt speed adjustment method. The present invention can be applied to the case where the transport speed of a conveyor belt located between an inner packaging production device and an outer packaging production device is adjusted during the cigarette pack production process. The method can be performed by a conveyor belt speed adjustment device. The conveyor belt speed adjustment device can be implemented in the form of hardware and / or software. The conveyor belt speed adjustment device can be configured in electronic devices such as personal computers and servers. Figure 2 As shown, the method includes:

[0032] Step S101 : determining in advance a mapping relationship between a conveyor belt motor speed and an operating speed of the outsourced production equipment according to relevant operating parameters.

[0033] The relevant operating parameters can be pre-stored in a memory and obtained by reading. They can also be input by an operator through a touch screen. After obtaining the relevant operating parameters, the motor speed corresponding to different operating speeds is determined.

[0034] Optionally, the mapping relationship between the conveyor belt motor speed and the operating speed is determined in advance according to relevant operating parameters, which can be implemented in the following manner:

[0035] Step 1: Obtain a phase pulse signal when the outsourced production equipment is running, and determine the running speed according to the phase pulse signal. Step 2: Determine a mapping relationship between the conveyor belt motor speed and the running speed according to relevant running parameters.

[0036] The faster the equipment speed, the faster the pulse signal sent. The operating speed of the outsourced production equipment can be determined based on the frequency value of the pulse signal. After the operating speed is obtained, the motor speed corresponding to different operating speeds is established, and then the mapping relationship is obtained.

[0037] Wherein, in step 1, determining the running speed according to the phase pulse signal can be implemented as follows:

[0038] The signal frequency is measured according to the phase pulse signal, and the operating speed of the outsourced production equipment is calculated according to the measured signal frequency.

[0039] Furthermore, before step 2, determining the mapping relationship between the conveyor belt motor speed and the operating speed according to relevant operating parameters, the method further includes:

[0040] Relevant operating parameters are obtained through the touch screen, and the relevant operating parameters include: a low-speed operating setting value of the packaging machine, a low-speed motor operating frequency setting value, a maximum operating speed setting value of the packaging machine or a speed compensation value.

[0041] The relevant operating parameters input by the operator can be received through the touch screen. The mapping relationship between the conveyor belt motor speed and the operating speed can be calculated based on the obtained relevant operating parameters.

[0042] Correspondingly, step 2 determines the mapping relationship between the conveyor belt motor speed and the operating speed according to relevant operating parameters, which can be implemented as follows: configuring the mapping relationship between the conveyor belt motor speed and the operating speed according to the low-speed operation setting value of the packaging machine, the low-speed motor operating frequency setting value, the packaging machine maximum operating speed setting value or the speed compensation value.

[0043] The equipment will often be manually cranked. When the equipment running speed is lower than the low speed value I set, the belt motor can be controlled to the low speed motor running frequency setting value. When the equipment running speed exceeds the set low speed value, the belt motor running frequency will follow the equipment speed linearly according to the above four values. Because the maximum running speed value of the equipment is often modified by the operator, and it is not running at a fixed maximum running speed, it is necessary to determine the linear relationship between the motor speed and the running speed by entering the above four values.

[0044] Step S102: In response to a start signal of the outsourced production equipment, the actual operating speed of the outsourced production equipment and the mapping relationship are acquired to determine a target speed of the conveyor belt motor.

[0045] When the outsourced production equipment is started or cranked, a start signal of the outsourced production equipment is received. In response to the start signal, the actual operating speed is calculated according to the operating frequency of the outsourced production equipment. According to the mapping relationship preconfigured in step S101, the target speed of the conveyor belt motor corresponding to the actual operating speed is determined.

[0046] Step S103: controlling the output power of the conveyor belt motor to adjust according to the target speed.

[0047] Optionally, controlling the output power of the conveyor belt motor to adjust according to the target speed may be implemented as follows:

[0048] The target voltage value corresponding to the target speed is determined through an analog module; the target voltage value is sent to the frequency converter through an output channel; the frequency converter is connected to the conveyor motor, and the frequency converter controls the conveyor motor to adjust the output power according to the target voltage.

[0049] Further, after the output power of the conveyor belt motor is controlled and adjusted according to the target speed, the method further includes:

[0050] It is determined whether the cigarette packs produced by the outsourced production equipment are skewed according to the detection signal on the output channel of the outsourced production equipment; if the cigarette packs are skewed, a shutdown alarm signal of the outsourced production equipment is triggered.

[0051] Wherein, judging whether the cigarette packs produced by the outsourced production equipment are skewed according to the detection signal on the output channel of the outsourced production equipment may be implemented as follows:

[0052] The distance signals sent by two photoelectric sensors symmetrically arranged on both sides of the output channel of the outsourced production equipment are obtained; if the two distance signals are different, it is determined that the cigarette package is skewed; if the two distance signals are the same, it is determined that the cigarette package is not skewed.

[0053] Figure 3An electrical schematic diagram adapted for the speed adjustment method of the conveyor belt provided in an embodiment of the present invention, wherein a programmable logic controller (PLC) is used to execute the above method, and a frequency converter is connected to the motor of the conveyor belt to control the motor output.

[0054] For example, the programmable logic controller may be a Siemens 1200 PLC, and the frequency converter may be a Siemens M440 frequency converter. The in-house production equipment may be a FOCKE350S equipment, and the outsourced production equipment may be a GDX2 equipment.

[0055] A Siemens 1200 PLC can be installed in the GDX2 packaging machine electrical cabinet. The PLC is powered by 450 (24V) positive and 451 (24V) negative. Connect the I0.0 pin to the GDX2 packaging machine encoder line 2A5962 / 913. The left cigarette pack detection B1 and the right cigarette pack detection B2 are respectively connected to 450 (24V positive) and 451 (24V) negative power supply (not shown in the figure), and the output lines are respectively connected to the I0.1 input point and I0.2 input point of the 1200 PLC. The detection signal is input through I0.1 and I0.2 to detect whether the cigarette pack is skewed. I0.3 is connected to the normally open contact of the 3K643 contactor in the GDX2 electrical cabinet to detect the packaging machine start signal.

[0056] The analog output channel 0 of the PLC is connected to the 3rd and 4th pins of the Siemens M440 inverter to control the inverter output frequency. The output point Q0.0 of the PLC is connected to the 26th point of the N11 board in the GDX2 packaging electromechanical cabinet to perform a shutdown alarm.

[0057] The L1, L2, and L3 terminals of the Siemens M440 inverter are connected to the lower end of the 3Q643 circuit breaker in the GDX2 packaging electromechanical cabinet to power the inverter. The U, V, and W terminals of the inverter are connected to the channel belt motor. The 5th and 8th terminals of the inverter are connected to another pair of normally open contacts of 3K643 to collect the start signal.

[0058] When the GDX2 packaging machine is in production, the 1200PLC will collect the 2A596 phase pulse signal of the GDX2 packaging machine encoder, measure the signal frequency, calculate the running speed of the packaging machine, set the corresponding parameters on the Siemens touch screen interface and send them to the 1200PLC to determine the proportional relationship between the belt motor speed and the packaging machine running speed. When the packaging machine is manually turning or running, the 1200PLC receives the running signal, and then sends the corresponding analog voltage value to the Siemens M440 inverter through the 1200PLC analog module output channel 0 to control the motor speed to track the GDX2 packaging machine speed for automatic adjustment. Two photoelectric sensors are added to the channel to detect the end faces on both sides of the cigarette pack, and the sensor signals are collected through the Siemens 1200PLC. When the cigarette pack is skewed, the two sensors will not detect the cigarette pack at the same time, and the 1200PLC will stop the alarm signal GDX2 packaging machine to prevent the cigarette pack from blocking the fifth wheel.

[0059] By automatically adjusting the speed of the channel belt between the FOCKE350S packaging machine and the GDX2 packaging machine, it can match the running speed of the GDX2 packaging machine, preventing the fifth wheel from being blocked due to excessive or slow belt speeds, and can be adapted to different packaging machine's fastest production speeds. It is more efficient to adjust than changing the belt speed by mechanically changing the pulley transmission ratio. A cigarette pack skew detection is also installed to prevent the fifth wheel of GDX2 from being blocked to the greatest extent.

[0060] The speed adjustment method of the conveyor provided by the embodiment of the present invention determines the mapping relationship between the conveyor motor speed and the operating speed of the outsourced production equipment in advance according to relevant operating parameters; in response to the start signal of the outsourced production equipment, the actual operating speed of the outsourced production equipment and the mapping relationship are obtained, the target speed of the conveyor motor is determined, and the output power of the conveyor motor is controlled and adjusted according to the target speed. Compared with the current manual adjustment of the conveyor motor, the speed adjustment method of the conveyor provided by the embodiment of the present invention can determine the target speed of the conveyor motor according to the operating speed of the outsourced production equipment and the predetermined mapping relationship after the outsourced production equipment is started. According to the target speed, the conveyor motor is controlled to adjust, and then the transmission speed of the conveyor is adjusted in real time according to the operating speed of the outsourced production equipment, so as to realize automatic, fast and accurate conveyor control and improve the efficiency and accuracy of conveyor control. When the conveyor transport speed matches the operating speed of the outsourced production equipment, the problem of subsequent equipment being blocked due to the slow conveyor transport speed can be avoided. By adjusting the conveyor transport speed and detecting the skewness of the cigarette box, the problem of subsequent equipment being blocked due to the skewness of the cigarette box can be avoided, and the reliability of cigarette pack production can be improved.

[0061] Figure 4 1 is a flow chart of a method for adjusting the speed of a conveyor belt provided by an embodiment of the present invention, comprising:

[0062] Step S201, obtaining relevant operating parameters through the touch screen, wherein the relevant operating parameters include: a low-speed operating setting value of the packaging machine, a low-speed motor operating frequency setting value, a maximum operating speed setting value of the packaging machine or a speed compensation value.

[0063] Step S202: Acquire a phase pulse signal of the outsourced production equipment when it is running, and determine the running speed according to the phase pulse signal.

[0064] Step S203, configuring a mapping relationship between the conveyor belt motor speed and the operating speed according to the packaging machine low speed operating setting value, the low speed motor operating frequency setting value, the packaging machine maximum operating speed setting value or the speed compensation value.

[0065] Step S204: In response to the start signal of the outsourced production equipment, the actual operating speed of the outsourced production equipment and the mapping relationship are acquired to determine the target speed of the conveyor belt motor.

[0066] Step S205, determining a target voltage value corresponding to the target speed through an analog module; sending the target voltage value to a frequency converter through an output channel; the frequency converter is connected to the conveyor motor, and the frequency converter controls the conveyor motor to adjust output power according to the target voltage.

[0067] Step S206: Acquire distance signals sent by two photoelectric sensors symmetrically arranged on both sides of the output channel of the outsourced production equipment.

[0068] Step S207: If the two distance signals are different, it is determined that the cigarette package is skewed, and a shutdown alarm signal of the outsourced production equipment is triggered.

[0069] Step S208: If the two distance signals are the same, it is determined that the cigarette package is not skewed, and the shutdown alarm signal of the outsourced production equipment is canceled.
