Abstract
In the process of cigarette packing, cigarette groups (10) to be packed into boxes are checked to guarantee the actual cigarette number. As contactless monitoring, a light emitter (22) and a receiver (23) are arranged on a bracket (cantilever (21)) positioned above a transmission channel of the cigarette groups (10). Therefore, if the cigarette number of a top layer (17) is correct and the form of cigarette on the top layer (17) is normal, a checking light beam (26) from the light emitter (22) becomes a reflected light beam (27) through reflection and is received by the receiver (23).
Description
The invention relates to the cigarette in groups (group, of cigarettes) of vertical arrangement or the monitoring device of other elongated article.Be specially adapted in the transmission course, at least the upper strata (top layer) of cigarette detected, not enough or when inferior-quality cigarette occurring at the cigarette number, will trigger a signal.
In the cigarette pack process, to check that usually the single cigarette of cigarette case is put in preparation and whether the quality of one group of cigarette (group, of cigarettes) exists defective.The first step is checked the front and back (end inspection) of cigarette, or rather, generally is to carry out on the cigarette turntable behind the cigarette feeder hopper.The cigarette turntable is to be used for be transferred to the cigarette load-transfer device cigarette branch in groups or them.
Further check, whether complete for the number that detects cigarette in the group, of cigarettes especially, on (straight line) cigarette load-transfer device, carry out.In this case, the cigarette that keeps flat is moved along direction of transfer, can detect (top layer detection) to its upper strata.Up to now, this detection realizes with mechanical means always, mostly is to use profiling parts (tracer pin).Along with the transmitting moving of group, of cigarettes, tracer pin is in the upper surface slide of group, of cigarettes top layer cigarette, and when lacking the Linear Leaf Speedwell cigarette or Linear Leaf Speedwell cigarette quality defectiveness being arranged, the relative position of a tracer pin will change, thereby triggers a signal.
The top layer method of inspection of above-mentioned machinery has a lot of shortcomings.On the one hand, cigarette must be born mechanical pressure, and this can make dirty even damage cigarette.And this cigarette method of inspection is not suitable for high-speed packaging machine yet, because tracer pin can't be followed the tracks of quick relative motion, and produces uncontrollable beating.
U.S. Pat-4147173 discloses and has a kind ofly detected the device of cigarette bottom with optical means, can not damage cigarette, but whether it can not be used for detecting group, of cigarettes cigarette number complete.
The present invention relates generally to the top layer check of group, of cigarettes.Its objective is provides a kind of device of realizing this class check, and it can use on high-speed packaging machine flawlessly, and group, of cigarettes is detected accurately, also can any damage not arranged to cigarette.
In order to realize this goal,, be confirmed as top layer cigarette being done the contact pointless check with optical evaluation facility (optical transmitting set and receptor) according to device of the present invention.
Therefore the optical check method of cigarette does not rely on the relative motion of mechanical part, is unusual failure-free.And, can avoid cigarette to be made dirty and bear mechanical pressure.
According to the present invention, the Inspection equipment arrangement is fixed on the transmission passage top of group, of cigarettes, is equipped with optical detector (projector and receptor).Utilize these equipment, a branch of check light beam irradiates is on top layer cigarette, and the receptor that tilts to install can receive the light beam that reflects back from the cigarette cylindrical surface.If some receptors do not receive a branch of check light beam, Linear Leaf Speedwell cigarette quality defectiveness is just arranged or lack the Linear Leaf Speedwell cigarette at top layer so.As the reaction of this situation, will send a signal, so that in next step packaging process, reject this inferior-quality group, of cigarettes.If many inferior-quality group, of cigarettes are differentiated that wrapping machine will stop, so that the cause of trouble-shooting continuously.
According to the present invention, Inspection equipment is made up of with several projectors and receptor a support that is designed to cantilever.Projector commonly used is a light-emitting diode, and receptor is a photistor, and both numbers are consistent with the number of top layer cigarette.Projector and receptor are corresponding one by one, and are installed in and cigarette position one to one, so that every bundle can shine on the cylindrical surface of every predetermined cigarette from the check light beam of projector, and reflex to receptor.A luminous spot appears on the cylindrical surface of cigarette, because projector and receptor are positioned at suitable bevelled position, hot spot departs from the side regions formation at cigarette top in a circumferential direction as a result.
Projector and receptor preferably are operated in infrared band.Infrared ray or check light beam will be with suitable cycle emissions.Concrete example as, with being about 5 kilo hertzs frequency, emission periodically, like this because the root of the caused error of ambient light just can be got rid of.Projector and receptor are only worked in the time that limits, and in this way, the length of cigarette 95% can obtain check.On the one hand, this can detect cigarette and whether lacks filter tip; On the other hand, when the check light beam is positioned at outside the cigarette, fail.
