Definitions

  • the present invention relates to a method and apparatus for sorting and packaging vegetables and fruit, such as, for instance, cucumbers, gherkins, and cauliflowers.
  • this invention relates to a method for characterizing, selecting, classifying, sorting, and packaging products, such as vegetables and fruits, comprising the successive steps of:
  • packaging requires a special treatment. This is the case in particular when each product is to be packaged individually.
  • sealing machines which wrap the respective products individually with plastic and subsequently close this wrapper with a heat seal. These machines are generally known to work best with a continuous product supply and also at a constant speed.
  • the invention provides a method for packaging products, such as vegetables and fruits, utilizing a sorting machine, the method comprising the following steps:
  • the method according to the invention comprises:
  • the major advantage of the method according to the invention is that only a single stream of products needs to be taken into account, so that logistics, both in terms of the construction of the apparatus and in terms of the control thereof, can be simplified considerably.
  • the uninterrupted in-feed of the products into the packaging unit takes place after collection and feed-through of these products with a buffer track.
  • the present invention also provides an apparatus for sorting and packaging products, such as vegetables and fruits, comprising:
  • the apparatus comprises:
  • the uninterrupted in-feed of the other products referred to is carried out with a buffer track.
  • the buffer track linking up with the main conveyor track, comprises, in succession, a first flat conveyor track, a roller track, and a second flat conveyor track, while the uninterrupted in-feed is effected from the control unit by controlling and configuring the individual speeds of the tracks.
  • a supply stream 1 of products is supplied to a sorting apparatus 10.
  • the products first enter a generally known feed roller track 11, for instance a single feed row with elongate rollers extending in transverse direction, or, for instance, hourglass-shaped rollers for more spherical products. In a known manner, these rollers are connected to endless chains on either side.
  • the products are passed along detection means 12, which, in a known manner, determine various characteristics of each product, such as weight, shape, color, and contaminations present on the surface.
  • detection means 12 which, in a known manner, determine various characteristics of each product, such as weight, shape, color, and contaminations present on the surface.
  • the data thus obtained are supplied as labels to a computer 14 along a signal path a.
  • the products are passed on to a main conveyor track 13, for instance a single row of transversely directed elongate cups for elongate products, or several rows of squarer cups for more spherical products.
  • discharge conveyor tracks 15 and/or packaging tracks 16 Connected to this track 13 are several discharge conveyor tracks 15 and/or packaging tracks 16, which, in most cases, pass under track 13, so that the products can be discharged from track 13 onto tracks 15, 16, typically endless conveyor belts, sometimes in the form of brush conveyors.
  • the discharge of the products takes place through control from a control unit of the computer along signal path a, in accordance with product classes previously set for the tracks 15, 16 and assigned to the products in accordance with the data obtained.
  • the products in tracks 15, 16 are discharged as output streams 2 for direct transport, or to a packaging unit 17, for instance to be sealed, whereafter the packaged products are discharged as output stream 3 for further transport.
  • Fig. 2 shows a diagram of a sorting apparatus according to the present invention.
  • the diagram which for a number of components corresponds to that of Fig. 1, it can be seen that it is exclusively sorting that takes place along discharge conveyor tracks 15. This is to indicate that the packaging of the products does not proceed by this route. Instead, the output stream 2 of the products to be packaged is passed further to a buffer track 18. From the buffer track 18 the products proceed as a packaging supply stream 4 to the packaging unit 17 downstream thereof, whereafter they are carried off as packaged stream 5 for any further handling.
  • control unit of the computer 14 provides for the control and configuration of the individual speeds of the main conveyor track 13, of this buffer track 18, and of the packaging unit 17, indicated in the figure with the signal paths a, b, and c.
  • Fig. 3 shows in detail an exemplary embodiment of the apparatus according to the invention, in which buffer track 18 further comprises, in succession, a first flat endless track 20, a horizontal endless roller track 21, and a second endless flat track 22.
  • buffer track 18 further comprises, in succession, a first flat endless track 20, a horizontal endless roller track 21, and a second endless flat track 22.
  • corresponding signal paths b20, b21, and b22 are indicated.
  • buffering i.e., accumulating a store on buffer track 18 to thereby ensure an uninterrupted stream 4
  • the packaging unit 17 generally runs at a constant speed, all preceding operations will have to be adjusted accordingly as much as possible.
  • the speed of the main conveyor track 13 will be greater than that of the packaging unit 17.
  • the buffer track 18 constitutes the bridge between track 13 and the packaging unit 17.
  • roller conveyor 21 as schematically indicated in Fig. 3, comprises freely rotating and transversely extending rollers, the whole being designed as an endless track. With it, the supply, and in particular the interruptions in the supply, can be taken up. Also track 21 will continue to rotate as much as possible. If an interruption occurs in track 13, track 21 will continue to rotate until on track 22 the supply is interrupted to an undue extent. If the supply from track 13 is too large, track 21 is going to run slower for a while. The freely rotating rollers will generally be able to take up any damming up. When the stream is continuous again, the preceding speeds will be adjusted accordingly.
  • control unit must be supplied with or driven by signaling with product stream monitors, such as photocells, cameras, or the like. Depending on the selected control logic, a suitable number of monitors are arranged above or next to the buffer track 18.
  • a minimum of products also referred to as buffer limit, is furnished on track 22.
  • This limit will to a large extent determine the switch-on and switch-off and speed settings.
  • the products that have been passed to the packaging unit and have been packaged therein can optionally be fed into the sorting apparatus again to be subsequently sorted according to class. Naturally, such products which have meanwhile been packaged will then be selected as products that do not need to be packaged.
