Definitions

  • the present invention relates to an inclination indicator for loading machines having gripping means which are adjustable to an arbitrary angle of inclination in relation to a reference plane, for instance the fork on a fork truck.
  • the purpose of this is to enable the driver of the loading machine to adjust the inclination of the gripping means to a position which is most suitable for gripping the go ⁇ ds.
  • the fork When loading piled goods as boards with a fork truck the fork is entered into spaces in the pile of goods. It is then important that the fork has the same inclination as the spaces, or otherwise the fork may damage the boards where it is entered.
  • the clamping means When loading cylindrical objects as paper rolls with a clamping truck, the clamping means bearing on the cylindrical surface of the roll, it is important that the contact of the clamping means with the roll is parallel to the axis of the roll. If the clamping occurs at an angle to the axis the roll is damaged by the shearing in the outer layers of the roll which is caused when the roll during .the continued clamping movement strives to turn towards a position where the axis of the roll is parallel to the clamping contact line.
  • an inclination indicator suitably of an electronic type, consisting of a sensor, for instance a potentiometer, which detects the angular position of the fork in relation to a reference plane, for instance the plane defined by the supporting surfaces of the wheels, and a pointer which shows the position detected by the sensor.
  • Fig. 1 shows a fork lift truck with a fork for piece goods or piled goods and an inclination indicator according to the invention.
  • Fig. 2 shows a clamping truck with clamping means for gripping a paper roll or similar and an inclination indicator according to the invention. The figure shows the clamping means in their correct position.
  • Fig. 3 shows the same clamping truck as in Fig. 2 but with the clamping means in an incorrect position.
  • the truck 10 shown i Fig. 1 is in a known way provided with a fork 11 which is vertically adjustable on a lifting frame 12.
  • the fork is placed at 90 angle to the frame.
  • the frame can be inclined to different angles and in the figure an inclination forwards is marked xo and an inclination rearwards is marked yo.
  • the angles are related to the line 15 which is perpendicular to the plane 16 of the ground.
  • the lifting frame is inclined a certain angle forwards or rearwards the fork 11 is inclined by the same angle downwards respectively upwards in relation to the plane 16 of the ground, the plane 16 thus being the reference plane for the inclination of the fork.
  • the inclination of the frame and the fork is detected by the sensor 13 and registered on the pointer device 14, so that the truck driver can adjust the fork to the desired position.
  • the horizontal position is used when the fork is entered between the boards in a pile, an inclination upwards is used in order to prevent the goods from sliding off, and an inclination downwards is used for unloading.
  • Figs. 2 and 3 show another type of loading machine, a truck with a clamping device for gripping objects.
  • the clamping device has two clamping arms 20 adapted to grip on opposite sides of a paper roll 21 placed with its axis vertically.
  • Fig. 2 shows the clamping device adjusted to the correct angular position so that the clamping contact surfaces of the clamping arms are parallel to the axis of the paper roll and thus bear on the surface of the roll.
  • Fig. 3 shove an incorrect angle of the gripping device, which results in a point contact between the clamping surfaces and the paper roll, with subsequent damage on the roll at the contact points.
  • the ground is the reference plane.
  • the indicator will thus register the inclination in relation to the sloping plane. If instead it is desired to register a horzontal position independently of the possible inclination of the truck, this can be achieved by means of a plummet device to which the indicator is related.

Abstract

Indicateur d'inclinaison (14) pour machines de chargement (10) ayant des moyens de prise (11, 20) qui sont reglables avec un angle arbitraire d'inclinaison par rapport a un plan de reference (16). Les moyens de prise (11, 20) peuvent etre par exemple la fourche (11) d'un chariot elevateur (10) ou les moyens agrippeurs (20) d'un chariot elevateur agrippeur (10). Le but de l'invention est de permettre au conducteur du vehicule de chargement (10) de regler l'inclinaison des moyens agrippeurs (11, 20) sur une position la plus appropriee a la prise ou manipulation des marchandises (21).
