What gather due to video camera 102 is the photo of multi-layered paper 103, if therefore there is larger space in multi-layered paper 103 between each layer of paper, so can cause space between paper under strong illumination and form shade on paper, thereby cause the imaging shade of video camera 102, make to occur shade on collected photo and be mistaken for paper defects.
For solving the space problem between multi-layered paper 103, in a preferred implementation of checkout equipment of the present invention, consult Fig. 2, in order to improve the accuracy of paper medical diagnosis on disease, checkout equipment also comprises a hold-down mechanism, for multi-layered paper 103 is pressed, to make each layer of paper seamless being close together as much as possible.Hold-down mechanism comprises a bowed roller 104.Bowed roller 104 is arranged on the walking path of multi-layered paper 103, and is positioned at the top of multi-layered paper 103.Light source 101 and video camera 102 are along the direction of travel AB of multi-layered paper 103 and after being arranged on bowed roller 104.By the effect of bowed roller 104, multi-layered paper 103 through it can be unfolded to bowed roller 104 two ends, to avoid multi-layered paper 103 to form fold, while, due to the effect of the arcwall face of bowed roller 104, in the time of multi-layered paper 103 process bowed roller 104, can make multi-layered paper 103 be close together, to reduce as much as possible the each layer of gap between paper, thereby avoid causing follow-up imaging shade because of the space between paper, can reduce thus the probability of erroneous judgement, improve the accuracy detecting.And, by each paper is pressed on together, can make the light transmission multi-layered paper 103 better of light source 101, the photo that video camera 102 is gathered is more clear, to improve the diagnosis of paper flaw.Multi-layered paper 103 is unfolding and pressing after effect through bowed roller 104, walk along AB direction, the high light line transmission multi-layered paper 103 of light source 101 when through light source 101, video camera 102 is uninterrupted gathers the photo of its below through the multi-layered paper 103 of the light transmission of light source 101, thereby diagnoses reference is provided for follow-up paper surface flaw.
Further, hold-down mechanism also comprises spreader roll 105 and hollow air roll 106.Spreader roll 105 and hollow air roll 106 are all arranged on the walking path of multi-layered paper 103, and contact with multi-layered paper 103.Wherein, spreader roll 105 is along the direction of travel AB of multi-layered paper 103 and before being arranged on bowed roller 104, and is positioned at the below of multi-layered paper 103.Hollow air roll 106, after the direction of travel of multi-layered paper 103 is positioned at bowed roller 104, and is positioned at the top of multi-layered paper 103.Each paper is at the formation multi-layered paper 103 that is superimposed after spreader roll 105, and multi-layered paper 103 passes through successively the effect of bowed roller 104 and hollow air roll 106 and is close together afterwards.Spreader roll 105 is for paper is unfolded to its two ends, and to avoid paper to form fold in high-speed cruising, hollow air roll 106 matches to make each paper to be close together better with bowed roller 104.Wherein, hollow air roll 106 is same plane with surface of contact and the bowed roller 104 of multi-layered paper 103 with the surface of contact of multi-layered paper 103, thereby makes multi-layered paper 103 flatly pass through the top of light source 101.
Owing to adopting intense light source to irradiate multi-layered paper 103, the light of light source 101 is stronger, and its heating is also comparatively serious, larger on the life-span impact of light source 101.Therefore, in order to extend the serviceable life of light source, consult Fig. 3, in checkout equipment of the present invention, be also provided with a cooling device 107.At least partly contiguous light source 101 of cooling device 107 arranges, and for light source 101 is dispelled the heat, remains in setting range with the temperature that makes light source 101.This setting range can be for example between 40-45 degree, or between 43-50 degree etc.In present embodiment, cooling device 107 is water-cooling apparatus, comprises water tank 1071, water pump 1072, water pipe 1073 and cooling dome 1074.Wherein, cooling dome 1074 covers are established the non-exiting surface of light source 101, and are connected with water tank 1071 by water pipe 1073.Water pump 1072 is connected with water tank 1071, passes through cooling dome 1074 with the water circulation of controlling water tank 1071.In the time of water circulation process cooling dome 1074, the heat of light source 101 can be taken away, thereby light source 101 is dispelled the heat.Wherein, can regulate by controlling water the heat-sinking capability of cooling device 107 through the speed of cooling dome 1074, or the temperature of the water by controlling 1071 li, water tank regulates the heat-sinking capability of cooling device 1071, thereby keeps within the specific limits with the temperature that makes light source 101.In addition, in order to improve the utilization factor of light, can smear reflection horizon in the face of the one side of light source 101 at cooling dome 1071, with by the light reflection that is irradiated to cooling dome 1071 to multi-layered paper 103.
In other implementations, cooling device 107 also can adopt air-cooling device, for example, use fan light source to be dispelled the heat etc.
In testing process, conventionally need operating personnel to operate, this just makes the high light line of light source 101 easily enter human eye and human eye is damaged, therefore, inject human eye and human eye is damaged for fear of the high light line of light source 101, continuing to consult Fig. 3, in checkout equipment of the present invention, picture collection device also comprises a chopping mechanism 107, and its light that is positioned at light source 101 transmits a side of multilayer dose 103, enters human eye to block the light transmiting from multilayer dose 103.The position of chopping mechanism 107 can arrange according to actual operating position, enters human eye and can not block video camera 102 image acquisition of multi-layered paper 103 is as the criterion can block the light of light source 101.Chopping mechanism 107 comprises window-blind 1071 and two bracing frames 1072.Multi-layered paper 103 is between two bracing frames 1072, and the two ends of window-blind 1071 are separately fixed on two bracing frames 1072, and two bracing frames 1072 can fix on the ground, and multi-layered paper 103 passes through between two bracing frames 1072.Window-blind 1071 is fixed on the diverse location of bracing frame 1072 alternatively, to make the height of window-blind 1071 relative multi-layered papers 103 adjustable, and the light quantity that adjustable blind 1071 shuts out the light thus.Preferably, window-blind 1071 remains on 3～5 centimetres of left and right, paper top apart from the distance of multi-layered paper 103, certainly, can need to adjust according to shading the height of window-blind 1071 relative multi-layered papers 103.Wherein, can window-blind 1071 be suspended on bracing frame 1072 by rope, in the time need to adjusting the height of window-blind 1071, only rope need be tied up to the relevant position of bracing frame 1072; Can also use a support bar through window-blind 1071, the two ends of support bar are separately fixed on bracing frame 1072 so that window-blind 1071 is fixed on bracing frame 1072.
Consult Fig. 4, in the another embodiment of checkout equipment of the present invention, checkout equipment also comprises pick-up unit, for the picture collecting according to picture collection device, multi-layered paper is carried out to disease detection.By the picture of video camera 102 multi-layered paper that collects, pick-up unit can carry out to multi-layered paper 103 the paper disease detection such as joint, perforations adding glue, holes, dark foreign matter and serious dead line, and can carry out respective handling to paper according to paper defects type.
Particularly, pick-up unit comprises parsing module 401 and processing module 402.Parsing module 401 is connected with video camera 102, resolves to obtain paper disease information for the picture of multi-layered paper 103 that video camera 102 is collected.In the time there is not the paper such as holes, dark foreign matter disease on paper, the taken picture of video camera 102 does not generally show shade, in the time there is paper defects on paper, can see the image shade causing due to paper defects on picture.Therefore, paper disease can embody by the shade on picture, and the shadow shapes that dissimilar paper disease shows is not identical.Parsing module 401 resolves to obtain the shade on picture to picture, then obtained shade and predetermined picture shade are compared, thereby size, shape and the monochrome information etc. that obtain the shade on picture that video camera 102 obtains, size, shape and the monochrome information etc. of the shade obtaining are paper disease information.
Processing module 402 is connected with parsing module 401, compare for paper disease information that parsing module 401 is obtained and all paper disease informations of pre-stored, to judge paper disease type corresponding to paper disease information being obtained according to comparative result, and according to paper disease type corresponding to obtained paper disease information, multi-layered paper 103 is done to predetermined process.Particularly, first pre-stored various paper disease informations, and preset every kind of corresponding paper disease type of paper disease information, and preset every kind of corresponding processing mode of paper disease type.After processing module 402 contrasts obtained paper disease information and pre-stored various paper disease informations, in the time that contrast obtains the paper disease information of the pre-stored consistent with obtained paper disease information, paper disease type corresponding obtained paper disease information is judged as to the corresponding paper disease type of paper disease information of this consistent pre-stored, thereby obtains the paper disease type that obtained paper disease information is corresponding.
For example, preset shaded area and be greater than 100 square millimeters, and the corresponding paper disease type of shade being shaped as is into strips joint paper defects.Size, shape and the predefined shadow information of the shade on the picture that processing module 402 is obtained parsing module 401 compare, in the time judging that according to comparative result the size of the shade on the picture obtaining and shape all meet the size and shape of the corresponding shade of joint paper defects, judge that paper disease type corresponding to shadow information on obtained picture is joint paper defects.And for example, the brightness that presets shade is holes paper defects higher than certain value or the inhomogeneous corresponding paper disease type of shade of shadow lightness.Processing module 402 compares the shadow lightness on obtained picture and predetermined brightness, judge according to comparative result when shadow lightness on the picture obtaining and the corresponding shadow lightness of holes paper defects are roughly the same, judge that paper disease type corresponding to shade on obtained picture is holes paper defects.
Obtaining after the paper disease type that obtained paper disease information is corresponding, according to the corresponding predefined processing mode of this paper disease type, the multi-layered paper 103 corresponding to obtained paper disease information does predetermined process.
In actual production process, some paper disease can be allowed to accept, and some paper disease is cannot be received, can preset and belong to acceptable paper disease type, and to the processing mode of this acceptable paper disease type, and preset and belong to unacceptable paper disease type, and processing mode to this unacceptable paper disease type.Particularly, in the present embodiment, processing module 402 obtains after the corresponding paper disease type of obtained paper disease information in judgement, then judges with unacceptable paper disease type whether this corresponding paper disease type is acceptable paper disease type according to predefined acceptance.In the time that processing module 402 judges that paper disease type that obtained paper disease information is corresponding is unacceptable paper disease type, according to the predefined processing mode to unacceptable paper disease type, processing module 402 is controlled ADF door and is opened, corresponding obtained paper disease information multi-layered paper 103 row's of being doors are processed, so that the multi-layered paper with unacceptable paper disease 103 is discharged.In the time that processing module 402 judges that paper disease type that obtained paper disease information is corresponding is acceptable paper disease type, according to the predefined processing mode to acceptable paper disease type, processing module 402 is controlled flag inserter the corresponding multi-layered paper 103 of obtained paper disease information is done to sign inserting processing, on multi-layered paper 103, plug label to carry out mark, to make in subsequent production process can to view by label near the paper that has paper defects label, be convenient to manually paper is again judged and screened, be conducive to improve detection efficiency.
For example, certain client can accept the paper defects of two types of dead line and foreign matter spots, but can not accept joint, perforations adding and three kinds of paper defects of holes.Before production, the paper that operating personnel preset butt junction, perforations adding and three kinds of paper disease types of holes in checkout equipment does the processing of row's door, and the paper of dead line and two kinds of paper disease types of foreign matter spot is done to sign inserting processing.In the time that the paper disease information that processing module 402 is obtained according to parsing module 401 judges that the paper disease type of detected multi-layered paper 103 is any in joint, perforations adding and holes three types, processing module 403 is controlled ADF door and is opened, multi-layered paper with unacceptable paper disease type 103 is got rid of, in the time that processing module 402 judges that the paper defects type of detected multi-layered paper 103 is any in dead line and foreign matter spot, processing module 402 is controlled flag inserter detected multi-layered paper 103 is done to sign inserting processing.By the way, can carry out multilayer detection to multi-layered paper 103, and compared with existing individual layer paper detection technique, can greatly improve detection efficiency, be conducive to reduce cost of labor.
Wherein, be acceptable paper disease type to exist the multi-layered paper 103 of paper disease to carry out sign inserting while processing to this when processing module 402 judges the paper defects type of multi-layered paper 103, be to carry out after paper knife cuts action to the sign inserting of multi-layered paper 103.But, from picture collection, judge that paper defects type is can life period poor to sign inserting processing procedure, this according to the difference of the speed of cutting a sheet of paper and difference mistiming, therefore in the time that the multi-layered paper that need to carry out sign inserting processing is carried out to mark, may there is sign inserting error, even speed of cut is too fast or excessively slow, likely cause label to be inserted in need to carrying out sign inserting multi-layered paper above or below.For example, once cut a multi-layered paper, in the time carrying out sign inserting processing, when speed of cut too fast, the a paper that makes to carry out sign inserting processing does not also have enough time to do sign inserting just to be processed and is covered by follow-up other paper that cut, and in the time that flag inserter carries out sign inserting, now label has just been inserted on other paper of paper top that need to carry out sign inserting processing; Otherwise, when speed of cut too slow, flag inserter has carried out that sign inserting is prepared but the paper that need to carry out sign inserting processing does not also have croppedly, and the label that now flag inserter does will be inserted in the below that need to carry out the paper of sign inserting processing, will cause thus sign inserting error.And owing to being that multilayer cuts, when detecting that the wherein a piece of paper in multi-layered paper opens with paper defects, system shows that this multi-layered paper has problem, can all carry out sign inserting processing to this multi-layered paper, therefore also can cause the error of actual paper defects position.
In present embodiment, can, by speed of cut being set to reduce sign inserting error, make label be positioned as close to the paper position with paper defects, preferably, can make sign inserting error be controlled in 10 cutter paper.Wherein, quire refers to the paper number once cutting, 10 cutter paper are exactly to cut rear obtained paper number for 10 times, and for example, the paper number once cutting is 5, once cut 5 layers of paper simultaneously, quire is 5 paper, and 10 cuttves are 50 paper, if the paper number once cutting is 3, quire is 3 paper, and 10 to cause be 30 paper.Therefore, sign inserting error is controlled at 10 cutter paper and refers to that with interior control need to carry out within the paper of sign inserting and label be all positioned at 10 cutter paper, so that follow-up personnel find paper defects position according to sign inserting quickly and accurately, confirm paper defects situation, this sign inserting error can be controlled by the control speed of cutting a sheet of paper.
Consult Fig. 5, in the another embodiment of checkout equipment of the present invention, pick-up unit also comprises computing module 403.Computing module 403 is for obtain total number of plies of the multi-layered paper that has paper disease according to the comparative result of processing module 402, to calculate the qualification rate of paper.After all paper disease informations of the paper disease information that processing module 402 is obtained parsing module 401 and pre-stored compare, in the time relatively obtaining the paper disease information of the pre-stored consistent with obtained paper disease information in the paper disease information in all pre-stored, illustrate that detected multi-layered paper exists paper defects, thereby obtain the number of plies of multi-layered paper, it is paper number, according to the constantly cumulative paper number with paper defects of the comparative result of processing module 402, thus can be by the paper number with paper defects divided by all paper numbers, thus qualification rate obtained.In addition, the paper disease type that computing module 403 can also judge according to processing module 402, adds up the paper number of various paper disease types, to calculate the accounting of different paper disease type, thinks that follow-up optimization production provides data foundation.
Checkout equipment of the present invention, in picture collection device, pass through to adopt intense light source 101, can make light transmission multi-layered paper 103, can make thus video camera 102 obtain the photo of multi-layered paper 103, while making arbitrary layer of paper in multi-layered paper 103 have paper defects, can be detected, the multilayer that therefore can realize paper detects, and greatly improves detection efficiency.And, by pick-up unit, can carry out paper disease detection to obtained picture, and automatically divide paper disease type, and the paper of different paper defects types is carried out to respective handling, and further improve detection efficiency, be conducive to reduce artificial and time cost.
The respective embodiments described above are all to describe as an example of paper example, checkout equipment of the present invention also can be used for the material that multilayer film, multilayer cloth etc. have similar features and carries out disease detection, its disease type of different materials is not identical, therefore can set according to actual conditions, not carry out repeating one by one at this.
