Description

Technical Field

[0001] The utility model relates to the field of cigarette manufacturing, in particular to an eighth wheel rejection fault alarm system for a packaging machine. Background Art

[0002] At present, packaging machines are one of the main production equipment of cigarette companies. Among them, the small pack machine (such as YB45) is a device that packs cigarettes into small boxes. In actual production, when unqualified products appear in the small pack machine, they need to be rejected. The rejection mechanism of the small pack machine is divided into cigarette rejection, aluminum foil rejection, trademark paper rejection, third wheel rejection, fifth wheel rejection, sixth wheel rejection and eighth wheel rejection.

[0003] Among them, the No. 8 wheel rejection station is used to reject cigarette packs with spliced ​​inner frame paper, cigarette packs without inner frame paper, cigarette packs without trademark paper, cigarette packs with incorrect trademark paper printing, cigarette packs that are burned by long equipment stoppage, and cigarette packs that are inspected by the No. 5 wheel appearance. It plays an important role in ensuring the product quality of small packs of cigarettes in the entire packaging process. However, in actual production applications, the No. 8 wheel rejection process often encounters the problem of excessive rejection leading to channel blockage, and even the No. 8 wheel mold box is blocked. In addition, there will be a situation where defective small packs caused by the failure of the No. 8 wheel rejection mechanism flow directly to the next process without being rejected, which seriously affects the overall quality of cigarette products.

[0004] Specifically, the electrical control of the No. 8 wheel rejection mechanism of the YB45 packaging machine uses a PLC output control relay, which controls the rejection solenoid valve mechanism. The solenoid valve is used to control the gas path conversion to achieve cigarette package rejection. The existing detection device only detects whether the circuit of the solenoid valve is working properly. For example, when the solenoid valve is short-circuited when rejecting a small package, the screen will alarm "No. 8 wheel rejection failure" to prompt maintenance personnel to check whether the No. 8 wheel rejection electrical circuit is normal.

[0005] However, as mentioned above, when the number of defective packets rejected by the No. 8 wheel rejection mechanism of the YB45 packaging machine reaches a certain number, there is currently no perfect detection and processing means. When the rejection channel is blocked, on the one hand, the No. 8 wheel is blocked, causing the equipment to overload and shut down. If the mold box is damaged, the equipment may need to be shut down for a longer time; on the other hand, when the rejection mechanism has a mechanical failure, especially when the air circuit fails, the No. 8 wheel rejection mechanism cannot reject the small packets, causing unqualified cigarette products to flow to the next process, and the existing detection mechanisms of the original machine are unable to achieve reliable detection of the above-mentioned No. 8 wheel rejection failure. Utility Model Content

[0006] In view of the above, the utility model aims to provide a packaging machine No. 8 wheel rejection fault alarm system to solve the above-mentioned technical problems.

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings, in which:

[0021] Figure 1 A schematic diagram of a No. 8 wheel rejection fault alarm system for a packaging machine provided by an embodiment of the utility model;

[0022] Figure 2 This is a reference diagram for assembling a photoelectric switch according to an embodiment of the present utility model. DETAILED DESCRIPTION

[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0024] The utility model proposes an embodiment of an alarm system for the eighth wheel rejection failure of a packaging machine. Specifically, the alarm system is installed at the corner of the filter rod storage bin (this position corresponds to the eighth wheel rejection station). Figure 1 As shown, it specifically includes: a reject barrel 1, a reject channel 2, a reject push rod 4, a reject cylinder 5, a reject solenoid valve 6, a reject relay 7, a controller 8 (the original machine controller can be used, or an independent controller can be configured. As shown in the figure, a control module of model 214-1AD23-0XB0 is selected), an alarm 9, a stop relay 10 and a photoelectric switch 12; wherein, the photoelectric switch 12 is installed on the reject channel 2, and its installation method is specifically as follows: Figure 2It is shown that two bolts 11-4, two second washers 11-6 and two second nuts 11-5 can be used to fix the detection bracket 11; further, the detection bracket 11 can be fixed to the rejection channel 2 using two countersunk bolts 11-2, two first washers 11-1 and two first nuts 11-3. In actual operation, a φ3 countersunk hole can be processed on the rejection channel 2 to fix the detection bracket 11; and a 32×15 square hole (not shown in the figure) can be opened on one side of the rejection channel, so that the probe of the photoelectric switch 12 can effectively detect the defective cigarette packs 3 (small boxes) in the channel through the square hole. Based on this, the square hole can preferably be 280mm away from the top of the rejection channel 2 and 25mm away from the rejection surface.

[0025] Continuing from the above, the rejection channel 2, the rejection push rod 4, the rejection cylinder 5, the rejection solenoid valve 6, the rejection relay 7, the controller 8, the shutdown relay 10 and the alarm 9 are all fixed on the packaging machine.

[0026] The rejection signal of the packaging unit is connected to the rejection relay 7 through a hard line. The rejection relay 7 is used to trigger the rejection solenoid valve to be energized to convert the rejection cylinder 5, thereby driving the rejection push rod 4 to reject the defective cigarette pack 3; in addition, the rejection relay 7 is connected to the controller 8 by electrical signals to represent the rejection state; the photoelectric switch 12 is used to detect defective cigarette packs 3. If the defective cigarette packs 3 block the probe of the photoelectric switch during the process of falling into the rejection barrel 1 through the rejection channel 2, the photoelectric switch 12 can feedback the signal of the rejection of the cigarette pack. It can be understood by those skilled in the art that during the rejection work, if the photoelectric switch 12 does not feedback the defective cigarette pack blocking signal, it indicates that there is a fault in the rejection mechanism, and the controller 8 can output an electrical signal to trigger the alarm 9 to output and trigger the shutdown relay 10 to be energized.

[0027] The purpose of setting the photoelectric switch 12 is not limited to the aforementioned detection and removal of defective cigarette packs in the removal process. For example, too many cigarette packs are removed, resulting in the cigarette packs piling up in the removal bucket, that is, there is a problem of clogging the removal channel. The photoelectric switch 12 can also detect that the removal bucket is full (such as the feedback level signal continues, so a first timer connected to the controller electrical signal can be set, and the first timer can be used to set the duration limit of the feedback signal of the photoelectric switch 12). At this time, the alarm can also be triggered and the shutdown can be triggered to prompt the operator to check the small packs in the removal channel in time to prevent excessive clogging of the removal mechanism.

[0028] Those skilled in the art can understand that the purpose of the present invention is to provide a set of hardware systems, and how to use the components therein can be set as needed. For example, in addition to the above-mentioned usage, the photoelectric switch 12 can also assist in detecting the number of rejections, and can trigger an early warning before the rejection barrel is filled. For example, the number of rejected cigarette packs detected by the photoelectric switch within a preset time period exceeds a certain limit. For reference, the number of rejections of at least 20 packs occurs within 1 minute (that is, the signal fed back by the photoelectric switch 12 can be used for counting, and a second timer can be configured to record the duration of the rejection process. The second timer has a different function from the first timer mentioned above), thereby triggering the alarm to output an alarm message. Of course, there is no need to trigger a shutdown in this usage scenario, and only an early warning prompt is required to indicate that the number of small packs rejected is too high.

[0029] In some other preferred embodiments of the present invention, the controller can also be connected to the emptying signal of the packaging machine equipment. The design of this circuit can shield the fault signal of the aforementioned alarm system during the emptying and idling stages of the equipment.

[0030] Finally, it can be added that the selection of relevant components in the aforementioned alarm system can be referenced as follows: the alarm 9 model can be selected as LTE-1081J; the detection bracket 11 can be made of 45# steel; the photoelectric switch 12 model can be selected as WT150-P460; the specifications of the aforementioned bolt 11-4 can be M3×20mm, and the specifications of the second gasket and the first gasket can be SS20×6×1.5; the specifications of the first nut and the second nut can be M3-0.5; the specifications of the shutdown relay can be selected as MY2N-GS24V.

[0031] In summary, the main design concept of the utility model is that it is composed of a rejection barrel, a rejection channel, a rejection push rod, a rejection cylinder, a rejection solenoid valve, a rejection relay, a controller, an alarm, a shutdown relay and a photoelectric switch. The rejection signal of the packaging machine is connected to the rejection relay, thereby triggering the rejection solenoid valve to be energized so that the rejection cylinder drives the rejection push rod to reject the defective cigarette pack; the rejection relay, the alarm and the shutdown relay are respectively connected to the controller electrical signal; wherein the photoelectric switch is installed on the rejection channel, and is used to detect defective cigarette packs and send cigarette pack existence signals to the controller. The utility model has a simple structure and reliable detection effect, and can provide hardware support for detection and alarm functions for a series of faults related to the rejection operation of the eighth wheel rejection mechanism of the packaging machine, thereby improving the operating efficiency of the cigarette equipment and ensuring the product quality of small cigarette packets.
