Definitions

  • the object of the invention is an apparatus for laying out root vegetables and other Solanaceae tubers in accordance with the preamble of claim 1.
  • Apparatuses are used to facilitate the laying out and choosing of root vegetables and potatoes and other Solanaceae tubers.
  • these apparatuses are called, among others, root vegetable automatons and/or potato automatons. These are most commonly used to ease both the work of the shop personnel and to help persons who shop to choose unpackaged root vegetables and potatoes.
  • the apparatus usually comprises a frame element and a lift unit/mechanism.
  • a storage box intended for products to be laid out is arrangeable on top of a lift cage lowered inside the frame element.
  • the apparatus is generally dimensioned so that the storage box can be hoisted approximately to a meter's height from the floor level.
  • the apparatus further comprises a front car which can be placed to the front part of the frame element.
  • a front car In its upper part there usually is a product bin, into which the products to be laid out run from a raised storage box for laying out and choosing.

  • the said guide track is substantially parallel to the direction of power generated by the said power generation device.
  • the power transmission device does not take up effective width of the apparatus.
  • the apparatus according to it has fewer danger inducing movable parts and that the location of these movable parts can be arranged to a safer place than in the apparatuses of previous solutions.
  • Figures 1 and 2 illustrate in an exemplary manner a side view of an embodiment of an apparatus of the invention for laying out root vegetables and potatoes and other Solanaceae tubers.
  • the apparatus has a frame element 10 with lift mechanism inside.
  • the power generation device 16 is attached to the lower part of the frame element 10.
  • the power transmission device 18 is attached from its first end to the power generation device 16 and from its second end to the lift cage 12.
  • the fastening of the power generation device 16 is anchored to the stationary frame element 10 and the fastening of the power transmission device 18 to the lift cage 12 moves as the lift cage 12 moves.
  • the guide track 14 has a groove, which is arranged to guide the travel of the bearing roller 24 and the lift cage 12 attached to it between planes. These planes are substantially parallel to the horizontal plane of the frame element 10 and/or the plane, onto which the frame element 10 can be placed.
  • FIG 1 there is illustrated the lift cage 12 belonging to the lift mechanism in its upper position, in which the push arm of the power transmission device 18 protrudes considerably from the inside of the power generation device 16.
  • Figure 2 the lift cage 12 is in its lower position, so that the power transmission device 18 and its push arm are considerably inside the power production device 16.
  • the joint length of the power transmission device and power generation device extends/shortens.
  • the power generation device 16 can be any device generating power, which can be arranged to generate the power needed to hoist the lift cage 12. It is obvious for one skilled in the art that the power generation device 16 used is required to have the elevating force and holding power required for the lift cage 12 and the load to be put in it.
  • the apparatus comprises one power generation device 16, which is an electric spindle motor according to known technology.
  • the apparatus also comprises control equipment for the power generation device 16 (not shown in the Figures 1-2 ).
  • the said control equipment is arranged to control the moving of the lift cage 12.
  • the control equipment switches can be located outside the frame element 10.
  • the switch boxes of the said control equipment containing the actual control system can be located inside or outside the frame element 10.
  • the push arm of the power transmission device 18 comprises a screw, i.e. a threaded arm part and a nut rotating in it.
  • the spindle motor is arranged to rotate the said nut, in which case, depending on the direction of rotation of the motor, the joint length of the spindle motor and screw either extends or shortens.
  • the spindle motor can be a motor in which the screw is rotated, and the nut remains unrotated.
  • the part to be hoisted i.e. the said lift cage 12
  • the joint of the push arm end with the lift cage 12 must be pivoted so that the rotary movement of the screw is not transmitted to the said lift cage 12.
  • the lift mechanism can also comprise more than one power generation device 16 and power transmission device 18. In this case the elevating and holding force required of an individual power generation device decrease.
  • the power generation device 16 such as a spindle motor, comprises a clutch mechanism protecting from mechanical overloading.
  • the clutch mechanism is arranged to slide when the elevating and/or holding force of the spindle motor is exceeded.
  • the switch mechanism prevents the hoisting of a load too large in relation to the strength of the apparatus.
  • the apparatus comprises an inductive position sensor (i.e. reed switch).
  • the inductive position sensor is arranged to define one or several automatic stopping points for the hoisting height of the lift cage 12.
  • the inductive position sensor is placed to the desired joint length of the power generation device 16 and power transmission device 18. In other words, the inductive position sensor is set to the desired hoisting height. In some embodiments, this means that the said position sensor is locked to the power generation device 16 or power transmission device 18 with appropriate fastening elements.
  • the apparatus comprises a component identifying the position data.
  • the component identifying the position data is arranged to identify the combined length of the power generation device 16 and power transmission device 18 (i.e. the hoisting height of the lift cage 12) and to inform this identified joint length electronically to the control equipment for the said power generation device 16.

  • the power generation device 16 can be, for example, a hydraulic cylinder, pneumatic cylinder or electric cylinder.
  • the power generation device 16 comprises substantially a frame with fasteners, a cylinder element and piston element.
  • the power transmission device 18 further comprises a push arm with fasteners substantially attaching to the piston element.
  • the hydraulic cylinder is arranged to be used by the power of a hydraulic pump or hydraulic circuit.
  • the said pneumatic cylinder is arranged to be used by the power of a compressor or pneumatic circuit.
