Definitions

  • the invention relates to a device for moving or grading agricultural products or other objects, which device comprises a frame which is movable along a path and which is provided with a supporting element on which a product may be present, which supporting element can pivot about a pivot axis with respect to said frame, from a substantially horizontal position to a sloping position, in which the product can fall from the supporting element, whereby said pivot axis extends substantially horizontally and in the direction of movement, which supporting element can be maintained in said horizontal position by means of a stop which is movable with respect to the frame, and which can be moved to said sloping position by moving said stop, which device furthermore comprises an electromagnet disposed beside said path, which can be turned on and off.
  • product or products used hereafter especially refers to agricultural products which must not be damaged or be loaded too heavily.
  • a device of this kind is known from GB 2 117 341.
  • a stationary lever mechanism is furthermore disposed along said path, which lever mechanism can be operated by turning the electromagnet on and off.
  • Said lever mechanism can be used for moving the stop of a frame provided with a supporting element, which passes the lever mechanism when moving along said path. The movement of the stop causes the supporting element to pivot from the horizontal position to the sloping position with respect to the frame, so that the product will fall from the supporting element.
  • a drawback of the known device is the fact that it is not very reliable, due to the fact that the lever mechanism must be operated at exactly the right moment each time, that is, at precisely that moment when a stop of a frame provided with a supporting element passes the lever mechanism.
  • the lever mechanism is liable to wear, which furthermore reduces the reliability of the device.
  • Another drawback of the known device is the fact that the lever mechanism is noisy.
  • the object of the invention is to provide a device for moving or grading objects, which does not exhibit the above drawbacks.
  • the device according to the invention is characterized in that the movable stop is provided with a metal part, which can be moved under the influence of the magnetic field of the electromagnet.
  • the stop Since the metal part moves directly under the influence of the magnetic field, the stop is moved without there being any mechanical contact between the moving frame and the operating device, which occupies a stationary position beside said path. Not only does this prevent wear, but also the production of noise is avoided. In addition, timing the movement of the stop is simpler under the direct influence of the electromagnet.
  • the device according to the invention is characterized in that the frame is provided with a stop which determines the exact sloping position of the supporting element in that the supporting element bears against said stop.
  • the device according to the invention is characterized in that more than one supporting element, preferably more than two, are provided on the frame.
  • the length of the frame will be increased as a result of this, which leads to an enhanced stability during transport, whilst the spacing between the respective products can be relatively small.
  • the device according to the invention is characterized in that a guide supports and guides the frame. This prevents the device from sagging with respect to the path, thus enhancing the reliability of the device, whilst the provision of a supporting rail, which is required in the device according to GB 2 117 341, will not be necessary.
  • the guide is made up of an aluminium section comprising two spaced-apart guide channels.
  • the frame and the guide may be shaped to complement each other, seen in cross-sectional view, in such a manner that the frame cannot be removed from the guide when it is present therein.
  • the device according to the invention is characterized in that several frames are interconnected by means of a chain. This makes it easy to move the frames along an endless path.
  • a frame is supported by said guide, whilst the chain is used for moving the frame.
  • the transport of the products will be more reliable.
  • the invention furthermore relates to a method for moving or grading products.
  • Figure 1 shows a frame 1 provided with a supporting element 2, on which a product 3, for example a potato, is present.
  • the frame is supported by a guide 4.
  • Guide 4 forms a path, along which frame 1 can be moved in a direction perpendicularly to the plane of the drawing.
  • Supporting element 2 can pivot with respect to frame 1 about a pivot axis 5, whose axis extends substantially parallel to the direction of movement of the frame, that is, perpendicularly to the plane of the drawing.
  • the supporting element takes up a horizontal position in Figure 1, in which position it supports product 3.
  • Frame 1 is provided on the underside, on either side thereof, with two supporting elements 6, 7, which each cooperate with a channel 8, 9 in guide 4. Supporting elements 6, 7 and channels 8, 9 are complementary to each other, seen in cross-sectional view. Frame 1 can only be removed from guide 4 when it is positioned at one end of guide 4.
  • frame 1 an supporting elements 6, 7 are made of plastic material, and guide 4 is an extruded aluminium section.
  • Supporting element 2 may also be made of plastic material so as to keep the production simple and reduce the noise level.
  • frame 1 is furthermore provided with a chain, the first link 10 of which is visible in Figure 1.
  • frame 1 is supported by guide 4, and the chain only functions to move the frame.
  • Frame 1 comprises a stop 11, which supports a cam 13 at its end, which cam mates with a corresponding cam 14 of supporting element 2.
  • Stop 11 is provided with a metal plate 15.
  • frame 1 has been moved perpendicularly to the plane of the drawing of Figure 1, and frame 1 is just moving past the electromagnet 16, which occupies a stationary position beside the path.
  • the electromagnet 16 is turned on, the metal plate 15 of stop 11 will be moved by the magnetic field, as a result of which stop 11 will pivot and the mating cams 13, 14 will be unlocked.
  • supporting element 2 pivots to a sloping position under the influence of the weight of product 3, in which position product 3 can fall from supporting element 2.
  • stop 11 which is preferably made of plastic material, will spring back to its vertical starting position. Supporting element 2 butts against the underside of frame 1, which forms stop 19.
  • stop 1 is provided with a hook 17, which cooperates with a cam 18 of frame 1. This prevents metal plate 15 from making mechanical contact with the electromagnet 16 upon passing. Electromagnet 16 takes up a slightly sloping position, so that contact between metal plate 15 and electromagnet 16 is prevented on the upper side as well.
  • frame 1 passes a guide rail 20, which rail is disposed perpendicularly to the plane of the drawing.
  • Figure 6 is a side view of a frame 1, which is not provided in a guide. Four supporting elements 2 are provided on frame 1. Figure 6 furthermore shows that the frame is attached to the links 10 of the chain by which frame 1 is moved along the path.
  • the electromagnet can be activated permanently so as to cause the products to fall from every supporting element that passes, but it is also possible to turn the electromagnet on and off each time. This may for example be the case when products must be graded for size or weight.
  • the electromagnet preferably has a laminated core in order to prevent eddy currents and thus generate a magnetic field quickly.
