Definitions
- the invention relates to a method and a device for sorting bulk goods in two fractions Color and / or shape according to the preamble of the main claim, corresponding to that known from EP-A-0 396 290 State of the art.
- Methods and devices for sorting out have become more recent increasingly for sorting out certain stones Particle size or color from a bulk material flow for Sorting ergot from bulk grain, for Sorting out glass of different colors and for sorting out of impurities from glass, for sorting from plastic to color or transparency and to Sort food and pharmaceuticals by Color, e.g. B. with French fries and corn flakes, or by shape, e.g. B. in case of tablet breakage and according to minimum sizes, e.g. B. of fruit, related.
- Color e.g. B. with French fries and corn flakes
- shape e.g. B. in case of tablet breakage and according to minimum sizes, e.g. B. of fruit, related.
- EP 0 550 944 Another device of the generic type is known from EP 0 550 944 known in the non-transparent particles of transparent Particles are separated.
- the device described there has the task set to sort particles of different sizes.
- the different trajectory is problematic here objects of different sizes. This is through a with grooves provided conveyor belt released. After the particles have separated from the conveyor belt, they go through a Flight route, being observed by a CCD camera whose signal to control blow-out nozzles, which correspond to the individual pixels of the CCD camera assigned, is used.
- the device is from the cited document unable to bulk different Shapes or sizes according to these characteristics sort by.
- EP 0 426 893 relates to one similar device in which by scanning at two Wavelengths are a color differentiation from green and brown glass should be made. A more universal Adaptation to other colors is not without further possible, and the image processing speed conceptually too slow to work efficiently to be able to.
- the invention is therefore based on the object of a method or a method To create device with which a sorting of various Bulk goods is possible and improved Sorting with the least possible wrong sorting at high throughput.
- Backlit camera instead of one in the bulk material flow Backlit camera also uses cameras be working under reflected light, or there may be one Combination of two cameras facing each other are used, each under reflected or transmitted light conditions work. Preferred is one under incident light conditions working camera with two fluorescent tube elements on both sides of the observation beam path are arranged. This can be used for Most applications have achieved low-cost lighting become.
- This enables an aluminum chip, that flies differently on longer free fall routes than for example broken glass on the chute from the broken glass is taken away so that it is the same Speed reached.
- the bulk material slide makes it possible to individual bulk particles on a conveyor belt to isolate a vibrating device.
- the vibrating device without bulk chute would leave upon leaving otherwise uneven output speeds produce. Through the bulk chute the output speeds have evened out.
- the advantageously easily replaceable bulk chute can also be provided with guide grooves with trapezoidal Cross section in the direction of the extension of the Bulk chute ensure that transverse movements of individual Bulk particles largely in straight motion is transferred. It is also advantageous that Bulk goods chute for different materials to produce different materials. Except for one Plastic version used in some applications due to electrostatic charges from a Bulk slide made of glass can also be replaced conceivable for food technology applications (e.g. Sort rice or cereals) a bulk chute made of metal with profiled guide grooves.
- the successive Line signals a two-dimensional, for a brief picture of the bulk material flow generated.
- Two-dimensional images are usually in the Television technology by scanning a two-dimensional Image area reached. However, it is also possible to use one to scan one-dimensional line if that Bulk goods, as in the present case, moved on uniformly.
- This two-dimensional image can be produced on a Screen are displayed, being particularly advantageous is when the ones to be blown out after image signal processing Particles are displayed in a different color.
- This allows the user to put him on the conveyor apparent sorting ratio with that of the device to visually compare the rejected sorting ratio.
- the correct detection of the objects clearly presented to the user at all times become.
- objects should be essential other shape or number on the screen Image signal processing than actually for example Seeing on the conveyor is a parameter the device, e.g. B. readjust the speed.
- this readjustment can also be automatic according to the blow-out statistics recorded and the user to carry out this readjustment appropriate signals, for example to a control center or alarm signals are announced.
- a is particularly advantageous here recursive filter, which is to be sorted out with homogeneously distributed Bulk particles, for example ergot and rye grain, with changing sorting statistics notify the user in good time can.
- the color is on both sides of an object can be checked independently of one another, so that if necessary both transmitted light and incident light information through combination in electronic image signal processing can be determined for a single object and this can be sorted accordingly.
- Fig. 1 they are both in the lateral directions up and down in guides 22 movable like pivotable blow-out nozzles 10 by a compressed air control 24 are controlled, shown.
- the guides 22, 36, etc., for adjusting the Angular and spatial relations of the individual parts to each other serve, are each laterally on the side walls of the Ball bearing guides arranged by machine.
- a conveyor belt equipped with a vibrating device (not shown) is in the upper area from the right the bulk material comes onto the bulk material chute 12 convey on which it is sliding down to the desired one Speed is accelerated, the bulk flow "pulled apart" and thus the particles isolated become. With an essentially straight-line continuation of their flight movement they become, as by the solid line and the one particle indicated, fall.
- the arranged essentially vertically to this Blow-out nozzles 10 cause certain air to be blown out Bulk particles in a sorting bulk channel 26.
- a bulkhead 16 is provided in bulk material with a pivoting device 18 via a continuous straight rod or plate connection coupled is to the exact location of the top edge of the partition 16 desired to place.
- Below shafts 26 and 32 are interchangeable drawers to catch the sorted good shown in the figure. Of course can larger containers or more here Processing plants follow.
- lighting means 14th provided that each consist of two parallel to Extension of the bulk material slide, i.e. perpendicular to the Fluorescent tubes parallel to the drawing exist between which there is a distance.
- this distance which is also a slit a radiation allowed from outside the device, the Line cameras used according to the invention the bulk material flow observe.
- at least one Camera (not shown) on the right and / or top left from the part of the device shown in the drawing placed to watch.
- Bulk particles either on the transparent bulk chute or preferably due to the lower optical interference observed just behind the bulk chute.
- reference numeral 34 is a device for pivoting the bulk chute 12 shown with reference numerals 36 the side guides to the Height adjustment of the bulk material slide. This is also also adjustable sideways, like this too for the blow-out nozzles through the guides 22 and for the Light elements 14 by provided in their attachment Guided tours are provided.
- the two-dimensional generated with this device Image is displayed on a color monitor, in particular it is advantageous that an image to build his many lines a certain time, for example one half a second needed while the rest of the picture stands still. During this half a second, a captured Bulk particles are stationary on the screen be recognizable so that its scope, color and size as well the amount of such particles is easily read by the user can be. Only after the line scan camera is sufficient Lines in the same place, but with moving bulk material flow recorded to fill an entire image, the display is replaced by a new one Image replaced.
- a user can use this for a comparatively long time Viewing time of a pixel can tell whether the summarizing object-indicating pixels to two-dimensional Image objects that should correspond to the bulk particles, is dealt with correctly by the electronics, or whether objects that are too large or too small are recognized. Possibly can be adjusted.
- this Representation also shows object inclusions in a different color can be. This is especially for applications beneficial in ore or rock for inclusions to be examined.
- color information can also be used for an object.
- you can also the color information on the front as well also the back by arithmetic means to one Total color information can be summarized that For example, sorting according to different types of waste glass Colors much easier.
- inclusions can also be recorded, it is possible to use the system also for bulk particles after a relation between own size and Sort out the size of an inclusion. This can be both sorting out those bulk particles, where the bulk goods parts with larger inclusions make processing worthwhile, as well as the reverse Case sorting out those bulk goods parts that have such large inclusions that post-processing or use does not appear to make sense.
- a color line sensor is used for color information acquisition, which has a FZKINT color line camera interface is suggested.
- FIG. 2 the incoming pixel data streams using a multi-stage pipeline processed. As input data serve the three color channels red, green and blue. You need to are available in digitized, 8-bit wide form, like some color line cameras or the FZKSAIM module used for simulation purposes. At the output of the processing stands for each pixel 8-bit wide color class information available on one line, which are fed to an SBIP / L module can.
- the desired color space coding of the individual Classes are created by the content of several lookup tables (LUT's) determined. The following will focus on the individual Processing levels of the pipeline were discussed in more detail.
- the first step is a line delay (Color Divergence). Their function is narrow with the geometric conditions of the camera used linked and was therefore physically the color line camera interface assigned.
- the FZKINT especially does justice to the fact that at some color line cameras the individual colors (red, Green and blue) are assigned to separate CCD sensors are. This creates significant problems in color identification of edges that are parallel to the CCD camera run because the individual sensors first successively receive the new color value. During the Transitional wrong color values are therefore read out.
- the problem can be solved, however, that the individual color channels depending on their spatial separation be delayed accordingly. requirement for this procedure is the constant speed of movement of objects that are also software controlled the corresponding delay time is coupled.
- the blue channel has no delay is provided.
- the objects must always be the first red, then the green and finally the blue color line happen.
- the pixel data stream reaches the FZKINT and reaches the CCD lookup tables on a color line preprocessing facility. There is then a separate LUT for each color channel available (rccd-LUT, gccd-LUT, bccd-LUT). She serves linearization and offset correction of the CCD sensor. It can also be used for white balance.
- Y 0.299 R + 0.587 G + 0.114
- the Color process the use of a recursive filter possible.
- the recursive filter works just like that shading correction on the brightness signal. In contrast to the latter, which the brightness differences within compensate for one line, this works recursively Filters as brightness correction across several lines.
- the color signals in the YUV space are also called chrominance referred to, which is advantageously independent of the Are luminance.
- Fig. 2 is finally within dashed lines
- the optional online statistics are shown, which are guided over the objects recorded in each case.
- the optional morphology processor is used for recursion.
- the angular relationships especially the bulk material slide the exhaust nozzles and the relative position of these to each other along the intended guides and angle adjustment devices if necessary, be changed automatically.
- Suitable sensors for e.g. humidity, temperature or similar environmental factors if necessary be provided additionally.
