Example 1

As shown in fig. 1, 3, 4 and 5:

the utility model provides a cigarette case parcel seals scalds preceding rake angle detection device, including cigarette case transmission device 1, cigarette case transmission device 1's both sides are equipped with the rake angle detector that is used for detecting whether there is the rake angle defect in the cigarette case, the rake angle detector adopts correlation formula photoelectric detector 2, the contained angle has between the detection light of correlation formula photoelectric detector 2 transmission and the transmission direction of cigarette case transmission device 1, the contained angle between the detection light of correlation formula photoelectric detector 2 transmission and the transmission direction of cigarette case transmission device 1 is the acute angle. As the most preferable detection scheme, the embodiment adopts the angle between the detection light emitted by the opposite-type photoelectric detector 2 and the transmission direction of the cigarette case transmission device 1 to be 45 degrees.

The opposite-emitting photoelectric detector 2 comprises an emitting end 201 and a receiving end 202, and the emitting end 201 and the receiving end 202 are respectively positioned at two sides of the cigarette case conveying device 1. The mounting bracket 3 is fixed on two sides of the cigarette case transmission device 1, and the transmitting end 201 and the receiving end 202 are respectively fixed on the inner walls of two opposite sides of the mounting bracket 3.

As shown in fig. 7, correlation formula photoelectric detector 2 still is connected with the PLC controller, acquire correlation formula photoelectric detector 2's detected signal through the PLC controller, when there is 7 defects in the cigarette case, when passing through correlation formula photoelectric detector 2, the rake can shelter from correlation formula photoelectric detector 2's light transmission path, make receiving terminal 202 can not receive the light that transmitting terminal 201 launched, correlation formula photoelectric detector 2 transmits the signal to the PLC controller that will sense this moment, PLC controller control cigarette case transmission device 1 stops the transmission, and keep this stop signal, cigarette case transmission device stops carrying the cigarette case, can avoid the cigarette case that has the rake defect to enter into little transparent machine, avoid cigarette case packing defect. Meanwhile, an alarm indicator lamp 5 connected with the manual reset switch 4 is turned on to prompt workers that problems exist in the production line and need to be treated in time.

When the working personnel take out the cigarette case with the rake defect from the cigarette case transmission device 1, the manual reset switch 4 is manually pressed, the manual reset switch 4 sends a signal to the PLC controller to switch on the control switch of the cigarette case transmission device, the cigarette case is restored to be supplied to the small transparent machine, and the alarm indicator lamp 5 is turned off.

Example 2

As shown in fig. 2, 3, 4 and 5:

the structure of the embodiment is basically the same as that of the embodiment 1, but the difference is that the number of the opposite-type photodetectors 2 in the embodiment is two, and an included angle between the detection light emitted by one opposite-type photodetector 2 and the transmission direction of the cigarette case transmission device 1 is 45 °. The contained angle between the detection light that another correlation formula photoelectric detector 2 launches and the transmission direction of cigarette case transmission device 1 is 90, through the correlation formula photoelectric detector 2 that sets up two different angles, even if there is the rake of a certain cigarette case and when the parallel cigarette case that leads to correlation formula photoelectric detector 2 to fail to discern the existence rake defect of light that one of them correlation formula photoelectric detector 2 took place, another correlation formula photoelectric detector 2 also can discern, realize the detection at all-round no dead angle.

As shown in fig. 5, the direction of the tilt angle of the cigarette case is parallel to the direction of the forward transmission of the cigarette case, and the tilt angle is detected by a 90-degree opposite-emitting photoelectric switch. As shown in fig. 6, the direction of the tilt angle of the cigarette case is perpendicular to the direction of the forward transmission of the cigarette case, and the defect is detected by a 45-degree opposite-emission photoelectric switch.

Example 3

As shown in fig. 7, the present embodiment has a structure substantially the same as that of embodiment 1, and is different in that a high-speed counter is further used in the present embodiment, the high-speed counter is connected to two opposite emission photodetectors respectively arranged at an included angle of 45 ° and 90 °, an output signal of the emission photodetector is connected in series by two output terminals of a solid-state relay, and then the output terminal of the solid-state relay is connected to an input terminal of the high-speed counter, the output terminal of the solid-state relay is a dc contactless switch, and the response is rapid, and the output terminal of the high-speed counter is connected to a PLC controller.

The early-stage experiment of the project finds that: the traditional electromagnetic relay is adopted and has no response to the defect of the rake angle vertical to the advancing direction of the cigarette packet (the photoelectric switch has a short pulse output, but the electromagnetic relay has no time to act), and the situation can be avoided by a high-speed counter.

After the high-speed counter catches a pulse transmitted by two correlation type photoelectric detectors 2 of 45 degrees or 90 degrees, the numerical value of the high-speed counter counting becomes 1, meanwhile, the normally open contact of the output module of the high-speed counter is closed, the output signal has a self-holding function, the high-speed counter can not be reset until the manual reset switch 4 is pressed down, the numerical value of the counter counting becomes 0, and the normally open contact of the output module of the high-speed counter is opened.

The high-speed counter transmits the sensed warping angle defect signal to the PLC, the PLC controls the cigarette case transmission device 1 to stop transmission, the stop signal is kept, the cigarette case transmission device stops conveying the cigarette case, the cigarette case with the warping angle defect can be prevented from entering a small-sized transmission machine, and the cigarette case packaging defect is avoided. Meanwhile, an alarm indicator lamp 5 connected with the manual reset switch 4 is turned on to prompt workers that problems exist in the production line and need to be treated in time.

When a worker takes out the cigarette case with the corner defect from the cigarette case transmission device 1, the manual reset switch 4 is manually pressed, the manual reset switch 4 gives a signal to the PLC to cancel the holding stop signal, the small transparent machine is allowed to start and recover to supply the cigarette case to the small transparent machine, and the alarm indicator lamp 5 is turned off.

Example 4

The difference between this embodiment and embodiment 3 is that, as shown in fig. 8, this embodiment may also use a high-speed counter alone without using a PLC controller, the high-speed counter is connected to two correlation photodetectors arranged at 45 ° and 90 °, the output ends of two solid-state relays connect the output signals of the two correlation photodetectors in series, and then the output ends of the two solid-state relays are connected to the input end of the high-speed counter, the output end of the solid-state relay is a dc contactless switch, and the response is rapid, the output end of the high-speed counter is connected to an electromagnetic relay, and the contacts of the relay respectively control the small transparent machine to stop, the cigarette case transmission device 1 to stop transmission, and the alarm indicator 5 to light up.

When a worker takes out the cigarette case with the corner defect from the cigarette case conveying device 1, the manual reset switch 4 is manually pressed, the manual reset switch 4 directly resets the high-speed counter, a holding and stopping signal is cancelled, the small transparent machine is allowed to start and recover to supply the cigarette case to the small transparent machine, and meanwhile, the alarm indicator lamp 5 is turned off.

Similarly, the results of the preliminary experiments of the project are as follows: the traditional electromagnetic relay is adopted and has no response to the defect of the rake angle vertical to the advancing direction of the cigarette packet (the photoelectric switch has a short pulse output, but the electromagnetic relay has no time to act), and the situation can be avoided by a high-speed counter.

The working principle is as follows:

when the invention is used, the cigarette case is conveyed on the cigarette case conveying device 1 and conveyed to the small transparent machine for wrapping and sealing transparent plastic paper, in order to detect the corner rising phenomenon at the front end of the cigarette case in advance and avoid the phenomenon that the small transparent machine cannot work normally or causes packaging defects caused by the corner rising, a correlation photoelectric detector 2 is arranged on the cigarette case conveying device 1 to detect the corner rising of the cigarette case, the detection is carried out by whether the light rays of the transmitting end 201 and the receiving end 202 are blocked by the corner rising, the detected signals are transmitted to a high-speed counter or a PLC (programmable logic controller) to be collected and control the small transparent machine to stop and the cigarette case conveying device 1 to stop conveying, when the defective cigarette case is taken out from the cigarette case conveying device 1, a manual reset switch 4 is pressed manually, the manual reset switch 4 is switched on a control switch of the cigarette case conveying device, the cigarette case is supplied to the small transparent machine again, meanwhile, the alarm indicator lamp 5 is turned off, and packaging is continued. The invention can automatically detect whether the cigarette case has a corner warping phenomenon before the cigarette case is wrapped and sealed, improve the working efficiency of the small-case transparent paper packaging machine and avoid the packaging defect.

The connection mode of the PLC controller and the high-speed counter in fig. 6 given in this embodiment is only for reference, the arrangement of the PLC controller and the high-speed counter is not a design point of the present invention, and the selection and the connection mode of the PLC controller and the high-speed counter may be a common connection mode in the art.
