Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco packaging equipment, and in particular relates to a diagnostic system for detection equipment on a mold box conveying channel of a packaging machine. Background Art

[0002] The GD type packaging machine mainly completes the packaging of cigarettes into cigarette packs and strip packs. The cigarettes are transported into the cigarette mold box (hereinafter referred to as the "mold box") through the lower cigarette channel to form a mold box cigarette group (hereinafter referred to as the "cigarette group"). The cigarette group is transported forward on the cigarette mold box conveying channel (hereinafter referred to as the "conveying channel"). The detailed conveying process is as follows: Figure 1 As shown, the cigarettes are conveyed downward to the lower cigarette channel 13 through the lower cigarette warehouse in the direction indicated by the second flow direction arrow 131, and the cigarette pushing row 14 reciprocates back and forth in the direction indicated by the movement direction arrow 141. The cigarette pushing row 14 pushes the cigarettes 12 onto the conveyor belt 11 to form a mold box cigarette group. A mold box horizontal smoke and disordered smoke detection device 15, a mold box cigarette group filter side blockage detection device 16, a mold box cigarette group filter missing detection device 17, and a mold box cigarette group empty head detection device 18 are arranged on the conveying channel. The above-mentioned detection equipments respectively perform quality inspection on the cigarette group on the conveying channel. If it is a defective cigarette group, it is rejected online at the rejection port 19 on the conveying channel in the direction indicated by the rejection flow direction arrow 191. If it is a qualified cigarette group, it is conveyed forward in the direction indicated by the first flow direction arrow 121 into the first round 192 of the packaging machine for subsequent packaging.

[0003] However, each detection device on the conveying channel only performs functional testing on the cigarette group at the detection position, without any diagnosis and judgment on whether the status of the detection device itself is normal. It is easy for the detection device itself to malfunction, resulting in the cigarette group being mistakenly rejected, causing increased production costs, or the detection device itself malfunctions without diagnostic monitoring, causing defective products to enter the market, posing a huge product quality risk.

[0004] The existing technology only monitors and diagnoses the safety interlock of the GD packaging machine, but is not suitable for diagnosing the various detection devices on the conveying channel of the cigarette mold box of the GD packaging machine. Therefore, how to diagnose the various detection devices on the conveying channel to avoid the problem of increased production costs and greater product quality risks due to the failure of various detection devices and the lack of relevant detection functions has become a technical problem that technicians in this field need to solve urgently.

[0026] In order to enable those skilled in the art to better understand the technical solution of the utility model, the solution will be further described in detail below in conjunction with specific embodiments.

[0027] like Figure 2 and Figure 3 As shown, an embodiment of the utility model provides a diagnostic system for detection equipment on a mold box conveying channel of a packaging machine, which includes a controller and an empty mold box detection equipment 31. The empty mold box detection equipment 31 is used to detect whether there are cigarettes in the mold box on the conveying channel, and the empty mold box detection equipment is arranged behind the rejection port 21 of the conveying channel; the mold box horizontal smoke and disordered smoke detection equipment, the mold box cigarette group filter side blockage detection equipment, the mold box cigarette group missing filter detection equipment, the mold box cigarette group empty head detection equipment and the empty mold box detection equipment 31 on the conveying channel are electrically connected to the controller respectively; the controller is electrically connected to the packaging machine control system, and the packaging machine control system is electrically connected to the upper monitoring platform of the packaging machine.

[0028] The diagnostic system for detection equipment on the mold box conveying channel of the packaging machine provided by the embodiment of the utility model has a controller that can make judgments and analyses based on the detection result signals transmitted by the empty mold box detection equipment 31, the mold box cigarette group filter missing detection equipment, the mold box cigarette group filter side blockage detection equipment, the mold box horizontal smoke and disordered smoke detection equipment and the mold box cigarette group empty head detection equipment, so as to better diagnose whether there is a fault in the detection equipment, and display the fault information on the upper monitoring platform through the packaging machine control system, so that the staff can promptly discover the fault of the detection equipment through the upper monitoring platform, and thus can effectively avoid the problems of increased production costs and greater product quality risks caused by the failure of various detection equipment and the lack of relevant detection functions.

[0029] It can be understood that the mold box cigarette group missing filter detection equipment is used to detect whether the cigarette group in the mold box lacks filters, that is, whether there is a missing filter defect; the mold box cigarette group filter side blockage detection equipment is used to detect whether there is a filter blockage defect in the cigarette group; the mold box horizontal smoke and random smoke detection equipment is used to detect whether there are horizontal cigarettes and random cigarettes in the cigarette group of the mold box; the mold box cigarette group empty head detection equipment is used to detect whether the cigarette group in the mold box has an empty head defect; the empty mold box detection equipment is arranged at the rear of the rejection port of the conveying channel, that is, in the conveying direction of the mold box, the empty mold box detection equipment is located downstream of the rejection port 21.

[0030] Furthermore, the controller is electrically connected to the packaging machine control system via a photoelectric coupler.

[0031] Preferably, the controller and the photoelectric coupler are both arranged in an electrical cabinet.

[0032] Furthermore, the empty mold box detection device 31 is connected to one side of the conveying channel through a mounting bracket.

[0033] Specifically, the empty mold box detection device 31 is arranged at the next mold box station of the rejection port of the conveying channel.

[0034] Preferably, the empty mold box detection device 31 is a photoelectric detector, such as a photoelectric detection switch. A high-speed module may be provided in the controller to process the signal output by the photoelectric detection switch at high speed, so as to ensure that the signal output by the photoelectric switch can be transmitted to the controller at high speed and stably.

[0035] The general diagnostic method of the above diagnostic system of the utility model is:

[0036] The empty mold box detection equipment, the mold box cigarette group filter missing detection equipment, the mold box cigarette group filter side blockage detection equipment, the mold box horizontal smoke and disordered smoke detection equipment and the mold box cigarette group empty head detection equipment respectively transmit the detection result signal to the controller;

[0037] When at least one of the mold box cigarette group missing filter detection device, the mold box cigarette group filter side blockage detection device and the mold box horizontal smoke and disordered smoke detection device detects that the cigarette group is defective, if the empty mold box detection device detects that there is a cigarette group in the mold box, the controller will determine that there is a rejection fault, and the controller will send a rejection fault signal to the packaging machine control system. The packaging machine control system transmits the rejection fault signal to the upper monitoring platform and displays it on the upper monitoring platform. At this time, it can be displayed as "rejection mechanism failure: rejection failure"; if the empty mold box detection device detects that there is no cigarette group in the mold box, the controller will not send a rejection fault signal to the packaging machine control system;

[0038] When the mold box cigarette group missing filter tip detection device, the mold box cigarette group filter tip side blockage detection device and the mold box horizontal smoke and disordered smoke detection device have not detected any defects in the cigarette group, if the empty mold box detection device detects that there is no cigarette group in the mold box, the controller will determine that there is an equipment failure and send an equipment failure signal -1 to the packaging machine control system. The packaging machine control system transmits the equipment failure signal -1 to the upper monitoring platform and displays it on the upper monitoring platform. At this time, it can be displayed as "detection equipment failure -1", indicating that the mold box cigarette group missing filter tip detection device, the mold box cigarette group filter tip side blockage detection device and At least one of the mold box horizontal smoke and disorderly smoke detection devices has a fault, and the staff needs to inspect and repair the above three detection devices one by one to eliminate the fault; in one embodiment, in order to facilitate the identification of which one or two of the above three detection devices have a fault, the detection result signals transmitted to the controller by the mold box cigarette group missing filter detection device, the mold box cigarette group filter side blockage detection device and the mold box horizontal smoke and disorderly smoke detection device can be numbered; if the empty mold box detection device detects that there is a cigarette group in the mold box, the controller does not send a device fault signal to the packaging machine control system;

[0039] When the mold box cigarette group empty detection device detects that there are empty cigarettes in the cigarette group, if the empty mold box detection device detects that there are no cigarette groups in the mold box, the controller will determine that there is a device failure, and send a second device failure signal to the packaging machine control system, and at the same time display the failure information through the upper monitoring platform. At this time, the displayed content may be "detection device failure 2", indicating that the mold box cigarette group empty detection device has a failure and needs to be repaired; if the empty mold box detection device detects that there are cigarette groups in the mold box, the controller will not send a second device failure signal to the packaging machine control system;

[0040] When the empty mold box cigarette group detection device does not detect any empty cigarettes in the cigarette group, if the empty mold box detection device detects that there is no cigarette group in the mold box, the controller will determine that there is an equipment failure, and send equipment failure signal 2 to the packaging machine control system. At the same time, the fault information is displayed through the upper monitoring platform. The content displayed at this time may be "Detection equipment failure 2", indicating that the empty mold box cigarette group detection device has a failure and needs to be repaired; if the empty mold box detection device detects that there is a cigarette group in the mold box, the controller will not send equipment failure signal 2 to the packaging machine control system.

[0041] It should be noted that regardless of whether the cigarette group has a hollow defect, that is, regardless of whether the hollow head detection device of the mold box cigarette group detects a hollow defect, the cigarette group should continue to be conveyed forward in the conveying direction on the conveying channel. This is because the cigarette group with this defect is not rejected at the rejection port 21 on the conveying channel, but should be rejected at the next rejection port.

[0042] Furthermore, while the controller sends the second equipment fault signal to the packaging machine control system, the controller calculates the number of steps for the current workstation to reach the next rejection port of the packaging machine and counts the steps. When the calculated number of steps is reached, the controller sends a rejection signal to the packaging machine control system to reject the cigarette group in the mold box at the next rejection port, thereby being able to reject the cigarette group with empty head defects.

[0043] Specifically, while the controller is counting the steps, the packaging machine stops supplying auxiliary materials to the mold box, ie, the mold box containing the empty defective cigarette group, thereby effectively saving auxiliary materials and reducing production costs.

[0044] The utility model realizes the collection of the detection result signals of each detection device through the controller, and then displays the detection result of each detection device on the upper monitoring platform through the packaging machine control system, so that the staff can realize the status monitoring of each detection device on the conveying channel on the upper monitoring platform; at the same time, the upper monitoring platform can not only be used to monitor the status of each detection device on the conveying channel, but also to perform equipment abnormality statistical query, equipment abnormality early warning display and control the opening / closing of the detection function of each detection device, among which the opening / closing of the detection function of each detection device can be realized by parameter setting and transmitting it to the controller via the packaging machine control system.

[0045] The utility model can realize visual monitoring and early warning of the status of each detection device on the conveying channel through the upper monitoring platform (when the controller determines that it is "detection device failure" after analysis, it indicates that the detection device itself has a failure risk. If the failure occurs three times in a row, an upper warning reminder will be issued to remind the staff to replace or repair the detection device in time), so as to reduce the failure rate of each detection device on the conveying channel and improve the supervision of the detection equipment; the controller can have a diagnosis and warning module, in which the logic of judging according to the output signal of each detection device mentioned above, the signal state judgment analysis and the early warning logic are designed in the diagnosis method. The utility model can also use the controller to count the defects caused by the failure of each detection device on the conveying channel, so as to improve the defect classification and statistical function of the packaging machine.

[0046] The utility model can realize the monitoring and diagnosis of each detection device on the conveying channel of the mold box cigarette group of the packaging machine, improve the effectiveness and accuracy of each detection device on the conveying channel, thereby improving the operating efficiency of the packaging machine and reducing the maintenance time of the packaging machine. At the same time, the utility model monitors the status of each detection device on the conveying channel, which makes it easier for the staff to grasp the operating status of each detection device on the conveying channel, reduces the downtime rate of the packaging machine caused by the failure of the detection device, and improves the production efficiency of the packaging machine.

[0047] The above are only preferred implementation modes of the present invention. It should be pointed out that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. Moreover, after reading the contents of the present invention, relevant technical personnel in the field can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
