Description
The present invention relates to be used to monitor and control the material of strip of wrapping material or similar articles or the device of position defective, this monitoring and control setup have detector, these detectors are used to detect continuous strip of wrapping material, and these detectors are photoemitter and receptor preferably; This device is applicable to package packing machine especially.
Interrelate with package packing machine, need monitoring material band, particularly strip of wrapping material.On the other hand, importantly will discern defect in material, for example the material band joint of adhesive tape is adopted in hole or tear in addition, or the like.When detecting such defective, just one or more parcels of making of the packing that contain these defectives-come out as cigarette case-go-on-go.Yet, further, also need to monitor the operation conditions of material band, that is to say and will monitor its relative position.When existing, just utilize suitable adjusting parts that material piece is adjusted on the correct sense of motion with desired position deviation.
At EP-A-25, a kind of such supervision and control setup have been described in 563.In this known solutions, a same Electro-Optical Sensor Set of reel carrier is cooperated, this Electro-Optical Sensor Set is made of by the detector that certain distance is provided with each other two row.Strip of wrapping material is from passing therebetween, and all has detector column to stretch in each side of material band, and these detectors are settled by fine pitch each other.Further, two lateral detectors (projector and receptor) are arranged in each row detector, they are used to the edge of test material band and survey have or not distortion.In this known devices, these last-mentioned detectors or error signal are used to start servomotor torque constant, and this servomotor torque constant is revised adjusting to reel or roller stand.
Although this known devices is suitable for monitoring the material and the position defective of material band, with regard to its installation and operation, this device needs higher expense.
The present invention based on purpose be to propose to be used to monitor the material of material band and a kind of device of position defective, this device is not only easy but also easy with regard to its installation, but it is unusual failure-free in operation.
In order to reach this purpose, determine that by at least two detectors or two groups of detectors these two groups of detectors are independently of one another according to device of the present invention, and be used for the test material band several materials or make feature.
In the optimum implementation of this invention, two groups of detectors independent of each other are arranged, these two groups of detectors can independent of each otherly start.First group only comprises two detectors, and specifically a projector and a receptor are used for monitoring the quality of materials of material band.In this occasion, be emitter design optical transmitting set (infrared transmitter) preferably, and receptor is designed to photodiode.The material band is carried between projector and receptor, and the light intensity that receives changes and is received device and notes, for example thicker the or thin part of material, tear, be used for interconnective material band termination adhesive tape altogether not, or the like.The error signal that receptor produced is used to coming out from one or more parcel go-on-gos of defective material band scope.
According to the present invention, one group of detector in addition, specifically, a projector and two receptors that are provided with by certain mutual spacing are used to monitor a material band (paper tinsel shape is opened band) that is added on the material band.In this case, receptor is by certain mutual spacing setting, and this spacing is opened the width of band less than this paper tinsel shape, covers so that make these two receptors be opened band by paper tinsel shape.Open band at this and departed under the entopic situation, just have on more illumination to one or another detector, and derive an error signal thus.
According to this invention, this group detector also has further function, monitors the relative position of packing section exactly, and these material segments divide from the material band to cut off together with opening carrying material.In order to reach this purpose, each paper tinsel shape open with on made a mark (colored resolution mark), the relative position of this mark is detected device and detects.The variation of its position also means a undesirable variation of packing section relative position.
According to further scheme of the present invention, these detectors and, if-suitably-other detector be set among the public single support of a U-shaped or on.These detectors of settling relative to one another (projector and receptor) are positioned on (level) straight-arm, the material band in a side has the scope of seam of opening by from carrying in the past between these detectors.These detectors are installed on the public U-shaped plate as carrier,
A kind of monitoring device of design-calculated is easy and simple to handle by this way, particularly be easy to assembling and ,-if necessary-replace.This whole device is configured to marketable device easy to use.
Other features of this invention are relevant with the structure design of this monitoring device, and relevant with its parts.
The concrete instance that is used as this invention of example below with reference to accompanying drawings is described in detail, in these accompanying drawings:
Fig. 1 is a lateral plan, the figure illustrates the device that is used to monitor the material band, and wherein the demonstration to monitoring component is a principle;
Fig. 2 is an end elevation, the figure illustrates device and material band according to Fig. 1, and its size has been dwindled;
Fig. 3 is a birds-eye view, and this figure interrelates with Fig. 2;
Fig. 4 has shown corresponding another embodiment as an example with Fig. 3.
Shown in the accompanying drawings, the monitoring as an example and the embodiment of control setup are particularly suitable for cooperating with wrapping machine, preferably cigarette packer.A material band 10 is made of the material such as the plastic foil film, and is infeeded a wrapping machine or a package packing machine (for example, a paper tinsel film device) constantly, and the relative position of this paper tinsel film, defective etc. are detected.These detections comprise material band 10 quality irregular (hole, tear, undesirable reinforcement) and be used for engaging the adhesive tape 11 of material band 10 in succession.
This monitoring device by one independently shell 12 form, or fully be contained in this shell 12.This device generally is oblong or cuboid in the present circumstance, it can entirely be installed among the wrapping machine or on, and can change as required.
Shell 12 has seam 13, stitches 13 off-center and in a side opening is arranged.Because seam 13, it is the shape of U-shaped basically that shell 12 has, and it is by arm 14 and 15 and the crosspiece 16 that arm 14 and 15 is joined to one another in a side formed.Material band 10 passes seam 13, and transversal with the length direction of shell 12.Material band 10 preferably moves along the direction of level.Monitoring component; Particularly optical detector or photodetector and device indicating and electronics and electrical device, all being installed in U-shaped shell 12 or design has in the shell of seam 13, seam 13 has opening in a side, and the main carrier of these devices is plates 17, it be U-shaped or with seam 13 designs together.At the edge of this piece plate,, formed the cross wall 18 that continues all around particularly along contour.This cross wall 18 also defines the both sides of seam 13.To suitably be connected to the outside as the covering wall 19 of the part of closed shell 12.
In the shown here optimum implementation as an example, defect in material with the first monitoring system test material band 10, this first monitoring system is made up of projector 20 and receptor 21, projector 20 is positioned at seam 13 thereby a side of material band 10 just, and receptor 21 is positioned at its opposite side.Projector 20 is launched a kind of detection media, Mai Dong infrared ray preferably, and this infrared ray is received device 21 and receives after passing material band 10.Radiation or intensity variations cause the corresponding evaluation of evaluation circuit, and if suitably, will produce error signal, this evaluation circuit is connected on after the receptor 21.In the scope of (upper and lower) cross wall 18, carry infrared ray by the flat window on the cross wall 22 and 23 respectively.Amplifier 24 is connected in the back of receptor 21.
In this embodiment as an example, (off-center ground) is connected to material band on the material band 10-especially open band 25-to monitor, this monitoring is independent of material band 10.Such unlatching generally is in the outside of the packing of parcel with 25, can be particularly on the outer paper tinsel shape packing of cigarette packs.For the purpose of the demonstration that makes Fig. 3 and Fig. 4 is clear, on material band 10, made imaginary horizontal partition line 26, horizontal partition line 26 be by material segment 27 determine that each material segment 27 is used to parcel of packing, these material segments 27 will divide from material band 10 after this and cut off.Unlatching stretches on the whole length of material segment 27 with 26, just stretches on material band 10.The leader that is used for grasping 28 that suppresses in advance is indicated at the not end of each packing section 27, and leader 28 time is used for grasping opening parcel.
In shown embodiment as an example, usefulness independently system is monitored existence and its accurate relative position of opening with 25, and this autonomous system is to be made of common emitter 29 and two receptors 30 and 31 by certain mutual spacing setting.Amplifier 32 is positioned at after above-mentioned each receptor.
Receptor 30 and 31 is by certain mutual spacing setting, and for example, about 1 millimeter, this spacing is slightly less than the width of opening with 25.Its result, when unlatching was with 25 to be disposed in the normal position, two receptors 30 and 31 were subjected to the latter's covering or are subjected to the irradiation of light.Departing under the entopic situation, in the receptor 30,31 one or another be receiving infrared-ray point-blank, has consequently triggered an error signal and begins unlatching is revised with 25 supply.
Under existing conditions, the monitoring system that has projector 29 and receptor 30 and 31 plays double action.For this purpose, in the embodiment as an example of Fig. 4, be used in the zone of leader 28 of grasping, provide on 25 in unlatching (colored) explanation sign 26.In this device, this is used as additional monitoring subsidiary, and the accurate relative position that especially is used for monitoring material segment 27 with respect to the article (not shown) that will pack, material segment 27 will divide from material band 10 and cut off.In order to reach this purpose, (colour) resolution mark 36 is detected with projector 29 or receptor 30,31.By rights its result is carried out evaluation, thereby when detecting the difference of relative position, just change the transfer movement of material band 10, thereby changed the relative position of packing section 27.
Because these monitoring systems are separate, therefore can regulate their sensitivity respectively according to the monitoring purpose.Further, with regard to the speed and the size and Orientation of device value of action, can divide other setting and adjusting to the control apparatus that interrelates with wrapping machine.
Infrared ray emits (2-5KHg) periodically by projector, in order that stop the influence of external light basically.In detect opening with 25 process, can select the relative position of parts so that make receptor 30,31 band that is unlocked separately cover half, in other words, provide they may provide power roughly half.In unlatching with 25 under the situations of centre operation, thereby initial value by amplifier 32 independently determine-these amplifiers are connected-make them about equally with each receptor 30,31, and its output signal is not represented any defective.(threshold value is to determine according to the lateral excursion that can allow.）
In this device, can carry out evaluation to signal in various manners.When in the amplifier 32 one or two all sent error signal, this can be sent to mouth to it as defective by the AND gate operation.Select as another kind, each amplifier 32 can send different signals, and for example one side is positive voltage and is negative voltage on the other hand.These two signals are sent to summing amplifier, and when unlatching moved in correct mode with 25, the output of this summing amplifier was zero.As the result who lags behind,, can determine to open allowed band with 25 offset from zero positions by means of potentiometric adjusting according to the positive and negative values of mouth.Simultaneously, by Correction and Control, can be with these on the occasion of the position of opening band being regulated again with negative value.Further, can produce a kind of signal thus, sort signal is used to defective parcel go-on-go is come out, or makes wrapping machine out of service.
