This conveyor terminates in a clod chute which discards to the ground all the material not removed therefrom. Removal of broken fruit is also possible with our technologies. While such electromechanical sorters work very well and have considerably sped up harvesting, they are not perfect. 4 is a fragmentary view in side elevation of a portion of the outwardly-moving clod conveyor shown in FIGS. After the tomatoes have gone through the after-sorting step they fall off an end 70 of the after-sorting conveyor 45 on to a front cross-conveyor 71, which crosses the entire width of the tomato harvester 10 and routes all of the tomatoes to one side. 2-4). Hear what our customers have to say and read some of their testimonials to discover how our technology is driving food safety, profitability and sustainability. The conveyor frame 60 can be rotated about the hinges 61 over a reasonable number of degrees. The vines then are carried out over the rear end 24 and dumped, while the tomatoes fall down below and are collected on a collector conveyor 25. a trash disposal chute in between said pre-sorting conveyor and its said platform segment. The tomato harvester of claim 6 having a trash disposal chute in between said pre-sorting conveyor and its said platform segment. TOMRA Sorting Solutions' pioneering industry expertise continues to result in state-of-the-art machines and exceptional service within the waste and metal recycling industries. 3,348,647. A rotating spinner 18 like that in U.S. Pat. A special feature of the present invention is that the outwardly-moving clod conveyor can be tilted to one side or another to cause many of the tomatoes to roll away from the clods, thereby making the job of transferring good tomatoes easier. They may also remove any green tomatoes, if there are any, although with the current state of the electromechanical sorting art, not many green tomatoes get by the sorter. 3,986,561, may be positioned in this gap 15 for the purposes described in that patent. Since the sorting systems along the two sides of the harvester 10 are identical or symmetrical only one of them will be described, and it will be understood that the other one is identical, though facing in the opposite direction. Photos obtained by CNN are beginning to show where some of the 671 mail sorting machines the United States Postal Service has planned to remove have ended up. Clods and any loose tomatoes that go along with the clod are carried out by the conveyor 50 toward a sorter who may remove good tomatoes and place them with the other good tomatoes. Complete customer satisfaction with service and support provided around the world 365 days per year. FIG. TOMRA tomato sorting machines identify and reject off-colored, rotten, molded, yellow shoulder, sunburned, breakers, under and oversized removal, and all ranges of foreign material including animal matter, metal, cotton stalks, plastic, stones, glass, wood, etc. A message from TOMRA Group CEO Stefan Ranstrand. Using the latest in illumination and detection technology, the Sentinel II outshines its competitors in sorting efficiency, capacity, technical specification, and durability. Discover our solutions here! The clods, not being round, do not roll very well and therefore are more likely to stay put, so long as the inclination is not too steep. In other instances, it is helpful if one side of the conveyor 50 is higher than the other. The common sorting and grading technique is manual sorting. Our UNI ONE, UNI ONE LF jolly and UNICAL 600 electronic sorters guarantee precision and accuracy in the selection of parameters such as color, diameter, volume and shape, in response to demands for enhanced processing in fruit & vegetable processing plants. 1 is a top plan view of a tomato harvester embodying the principles of the invention. A tomato harvester sorting system wherein tomatoes after detachment from the vines are collected and moved rearwardly to a rear cross-conveyor, comprising: a horizontal forwardly-moving pre-sorting conveyor on which fall the tomatoes from said rear cross-conveyor, having an adjacent platform segment for workers to stand on and remove vegetative trash, the tomatoes falling off the forward end of said pre-sorting conveyor. Moreover, when a large amount of green leaves or stems are mixed in with the tomatoes to be sorted, the green of the stems tends to cause the sorter fingers to move to a reject position so that red tomatoes entangled in or following very closely on the green leaves or stems may therefore be sent to the cull chute. One or two persons are stationed on a platform next to the pre-sorting conveyor, and their job is to remove all remaining green leaves, vines, or other vegetative trash. FIG. An electro-mechanical sorter judges the redness or greenness of tomatoes falling from the forward end of the pre-sorting conveyor and impels green tomatoes into a cull chute, while red tomatoes fall on to an elevating conveyor. Some portions are broken away to show parts underneath. 6. The actuated electronic circuit actuates a mechanically moved finger which acts quickly to divert each green tomato or dirt clod into a cull chute and which is then retracted to its normal position, so that red tomatoes can fall freely in a normal trajectory. Another problem with machines having electromechanical sorters is, that if one is to combine them with hand sorting to remove green leaves and stems and overripe tomatoes, then a very compact arrangement has to be made if one is to avoid having to extend the length of the harvester frame. At the bottom of their fall, the red tomatoes are collected on a moving elevator conveyor which has a series of flights and which raises the red tomatoes along an inclined path and deposits them of an after-sorting conveyor belt. Tomatoes can vary greatly in size and relative dimensions. 1. Normal sized tomatoes, such as the beef steak variety, can be sorted with 10 products per second per lane. 2 is a view in side elevation of the tomato harvester of FIG. Tomato sorting and packing machine. Recently, electromechanical sorters have come into use. The main purpose of the sorting workers her (there may be three or four) is to remove from the after-sorting conveyor overripe and defective tomatoes. No. FIG. This outwardly-moving conveyor is the terminal portion of the clod conveyor system, and there is one on each side of the harvester. Alternatively, he may drop the good tomatoes on to the belt 35, depending on which hand he is using, though use of the chute 55 is preferred. The tomatoes are then weighed electronically and sorted into 12 freely adjustable weight classes. a divider above said elevator and said first cull chute for separating tomatoes into a path leading to said elevating conveyor and a path leading to said cull chute. A tomato harvester 10 embodying the invention incorporates a suitable tomato pickup device 11, which may include a severing knife 12, a spaced-bar type of elevator 13, through which loose dirt can pass, and a second and more sharply inclined solid-belt elevator 14. The demands of consumers, however, are much less variable. All these are described in earlier U.S. patents, including U.S. Pat. TOMRA's material handling activities are complementary to its RVM business in North America. After the vines had been severed near their roots, the vines elevated and shaken, and the tomatoes detached from them, the vines were disposed of, and the tomatoes were collected and conveyed on one or more horizontal sorting belts past a long line of workers, typically a dozen or more at each sorting belt, each of whom would do his best to remove culls.
