Definitions

  • the invention relates to the field of sizing vegetables having a essentially elongated shape and mainly finds its application for the automatic calibration of asparagus.
  • the invention relates to a system for calibration automatic of such vegetables intended to be integrated into a processing chain in downstream of means designed to wash these vegetables and, in particular in the case of treatment of asparagus, to give them a uniform length.
  • the main objective of the calibration operation is to sort the vegetables by depending on their size. However, for certain vegetables and mainly for asparagus, such sorting must be carried out according to other criteria, in particular depending on the color of the asparagus (purple or white).
  • Another objective of the calibration is to be able to easily eliminate vegetables unfit for consumption, in the case of asparagus in particular those having a very flowered head or those with significant rust spots for example.
  • a more sophisticated device described in French patent FR 2 570 301 in the name of the applicant allows better sorting of asparagus according to their diameter.
  • this device is also based solely on the exploitation of the sorting criterion constituted by the diameter of the asparagus and therefore does not take into account has other criteria such as the color and shape of the asparagus. Now, such criteria are gaining increasing economic importance.
  • the asparagus is conveyed in buckets longitudinal and the optical recognition device includes taking means view of these asparagus in these pots.
  • the optical recognition device includes taking means view of these asparagus in these pots.
  • the main objective of the present invention is to solve this problem and in particular to propose a system for the automatic sizing of vegetables having an essentially elongated shape such as asparagus allowing optimize the operation of the optical recognition device and thus improve the quality of calibration.
  • Another object of the present invention is to provide such a system which can be implemented at high rates while involving the use a number of important sorting criteria.
  • Yet another object of the present invention is to describe such a system with new mechanical means for rapid sorting vegetables visualized by the optical recognition device.
  • the asparagus is not contained in pots at the time of recognition optics but are supported by a hoop system to remove all risk of the presence of elements other than asparagus, in particular water, time of this operation.
  • Conveying and sorting device modules proposed by the invention including hoops designed to support asparagus, no other element than these can be retained at the time of viewing.
  • these modules may include two or several arches. However in a preferred embodiment of the invention they will each have only two hoops, namely a fixed hoop that does not open pitch and, a movable mounted hoop that can open to release the asparagus and the distribute to the recovery means of the calibration system according to the evaluation of the sorting criteria carried out by the optical recognition device.
  • said means opening of said arch of each module include a bent rotary axis whose cam ends can slide in an upper side slide and in a lower side slide, said side slides being provided members for rotating said rotary axes enabling said passages to pass ends of the upper slide in the lower slide.
  • said members for rotating said rotary axes include keepers provided on said slides and likely to be actuated to allow the momentary lowering of ends of the rotary axes sliding in said slides.
  • these rotation members are preferably actuated by electromagnets. According to another embodiment, they can be also actuated by micro-cylinders.
  • each of the modules therefore has a hollow fixed axis to which the fixed arch is connected, the rotary axis being mounted movable inside this fixed axis.
  • the optical recognition device will be designed to allow the evaluation of several sorting criteria chosen from the constituted group by the diameter, the color, the shape, the presence of stains.
  • the calibration system comprises means 1 for supplying and individualizing the asparagus, an optical recognition device 2 of each asparagus coming from said supply means 1 and a device for conveying and sorting 3 the asparagus from the feed means 1 for sorting it and distributing it towards recovery means 4 according to the four sorting criteria evaluated by said optical recognition device 2 (diameter, color, shape).
  • the means of supply and individualization consist essentially of a carpet with cleats la whose movement is controlled by a geared motor device 1b, the space between two consecutive cleats being designed to receive one and only one asparagus.
  • Such feeding means are preceded by a double loading conveyor strip with conventional cleats (not shown in Figure 1) on which the asparagus, previously washed and cut, is placed.
  • the conveying and sorting device 3 comprises a chain of calibration 3a (not visible in Figure 1 but visible in Figure 2), supporting a plurality of modules 6 which will be described below in more detail, and the movement is controlled by a geared motor 3b.
  • the sorting and conveying device 3 also comprises means for recovery of asparagus sorted by this device including thirteen conveyor belts ejection 4 provided under the calibration chain 3a. Note that this device is also provided with a wheel 17 enabling the asparagus from the batten mat when transferred to the modules 6.
  • the asparagus optical recognition device 2 comprises a camera 5 placed above the sorting device 3 allowing the taking of view of all the asparagus arriving at this device, as well as a unit central 16 analyzing the data recorded by said camera and connected to the device for sort 3.
  • the axes 9 all have a bent end 10 forming a cam.
  • the conveyor and sorting device 3 comprises a side wall 3c provided with an upper slide 11 and a lower slide 1 la, in which the bent ends 10 can slide forming a cam of the modules 6.
  • This wall is moreover provided with passages 11c placing in communication the upper slide 11 and the lower slide 11a and a plurality of keepers 12 for passing the end of the fixed axis 13 from the upper slide 11 to the lower slide 11a through the passage 11c, this movement causing the rotation of this axis 13 and the opening of the arch 8 by separation of finger 8b from finger 8a.
  • These keepers 12 are actuated by electromagnets 14 (visible in FIG. 2) controlled by the central unit 16 of the device optical recognition 2.
  • the asparagus is transported after having been previously washed and cut by the batten mat la and are transferred one by one into modules 6 sorting device 3 scrolling at fast, constant and synchronous speed with that of batting carpet.
  • the wheel 17 maintains the asparagus during this one.
  • the end 10 of the module receiving the asparagus is held in the upper slide 11 of the side wall 3a of the device 3 corresponding to a closed position of the roll bar 8.
  • Each asparagus is then viewed by the camera 5 of the optical recognition 2.
  • the optical data relating to each asparagus is communicated to the central unit 16 which evaluates each of the sorting criteria of said sprinkles (diameter, color, shape) and assigns one of the thirteen outlets from the sorting device 3 corresponding to one of the thirteen ejection conveyor belts 4.
  • the visualization of asparagus is optimized because no other element than asparagus (water, various litter %) cannot be maintained in the module.
  • each asparagus contained in each module 6 to the ejection mat 4 assigned by the central unit 16 is carried out by opening the hoop 8 of this module above this mat.
  • This opening is caused by actuation of the keeper 12 corresponding to said mat, causing the passage of the angled end forming a cam 10 of the axis 9 of the module 6 of the slide upper 11 towards the lower slide 11a, passage causing the axis 9 to rotate and the separation of finger 8b from finger 8a.
  • the strike 12 is actuated caused by the corresponding electromagnet 14.
  • the hoop 7 being fixed and does not not opening, the asparagus is gently placed on the mat 4 which has been allocated to it. Once the asparagus is distributed on the correct conveyor belt, the hoop 8 is closed at the end of calibration chain.
  • the system described here thus makes it possible to quickly sort the asparagus into depending on their color, shape and diameter and provides up to thirteen lots of asparagus sorted according to these sorting criteria, one of the carpets being devoted to the recovery of non-marketable asparagus.
  • Such a system makes it possible to increase the degree of reliability of the sorting carried out while by authorizing very high processing rates.
