Description
Technical field
The present invention relates to the device and method for container of the inspection equipped with label.This method and apparatus is from the prior art
It is medium-term and long-term known.When disposing label, it should be noted that multiple standards.Therefore herein it should be noted that：Label is respectively along specific
Orientation, the orientation of such as straight line are arranged on container.One of this external demand is：Label is arranged on container in a manner of not abandoning
On.In addition, if the edge segments of such as label are deficiently equipped with binding agent, then can result in interference.The edge part
Section is then relatively quickly removed from container.
Background technology
From the inside of the application in the prior art, also have to check in the stickup on label acyclic
Around label on stickup known to so-called flag identification device.The flag identification device usually have grating and reflector with
And blow-out nozzle.Here, container is located at by the disk of servo motor driven.Similarly, belt driver equipped with the disk with
And slide is adjusted, so as to always in the identical angular position of container and also can be along fortune in the case where holding diameter difference
Defeated direction positioning identification object.
Tangentially-arranged grating inspection：Whether protruded during container rotates in labeller capstan head around label.This
It is used as checking：Whether the final sizing applicator at unit correctly works.Superposition between label beginning and tag ends
Flat burner is for example provided at region, when the flat burner will in case of a fault be identified around label, i.e. non-abundant
Or cause prominent in the case of lacking sizing or wave.Grating interrupts in case of a fault.
Because adjusting the superposed positions on container platform according to type under different container diameters, sensor is installed
Onto section slide, the section slide can be directed to according to type at the corresponding position on container platform.In addition it is also necessary to
Depth of field regulating device for the identification of accurate flag and the height adjustment device for each sensor, so as to match
In different viscose glue height.Fig. 1 a and 1b illustrate the processing mode.
The shortcomings that processing mode is：Grating always must be away from chamber wall extremely near-earth setting or the container that must recline
Wall is set.When container switches, it is necessary to carry out corresponding mechanical adjustment.
In addition, by grating being made to interrupt change hardly possible in case of a fault for good and all to rotate label ends turn away.This
Outside, in this design scheme disadvantageously：Sensor unit must always be matched with corresponding label height when type switches
Position.In addition, the device being made of the sensor and reflector of grating is necessarily placed on the outside of labelling machine capstan head, i.e., along
Tangent line setting at tracks.
Finally, also disadvantageously identification certainty.If such as superposition of the label with about 10mm and container with
Such as the cross section of 54mm, then label is 190mm long.If now the label surround 270 ° of container and --- such as scheming
In the vertical view shown in 1b --- it is protruded in a manner of shown, then 135.2mm reclines container, and remaining 58.8mm
It is protruded as flag.In this case, the vessel radius of 28.7mm is subtracted, is retained on the outer tangent line of tracks
26.1mm.Sensor in this case in order to by failure rate be kept as it is small and must be away from external tangent line about 10mm.It must be reliable
Interrupt the sensor hot spot of such as 7mm diameters in ground so that retain the spare portion of about 9mm in this example.
The inspection of label is infeasible at band, because container is transported with arbitrary turned position, with being no longer aligned with.
It is interfered by the frictional influence mode between machine outflux and/or the transition part of conveyer belt and/or container and container or railing
The similar turned position of the container taken.
