Definitions

  • the motor With the use of one single motor, the motor has to be "over-sized”, resulting in increased physical size, power consumption etc. of the motor.
  • Electro-magnetic coils merely generate a shake motion, but do not allow positioning of the shake table at the desired location. This also applies to separate X and Y plane solutions due to tolerances and to slack.
  • Linear shaking of a mobile plane is generated with the use of an eccentric control device attached to the shaft of the motor, the motion of the control device being limited by means of an opening, so that motion in one direction
  • Orbital shaking of a mobile plane is generated by using two mutually perpendicular mobile planes and two eccentrics.
  • the drawbacks of these solu- tions include wear of the parts, disturbing noise, especially at higher frequencies, and of high cost.
  • the system described below achieves both linear and orbital shaking with the same stepping motor without any separate gear box or change-over switch. Consequently, the actuating means of linear shaking and orbital shaking will be mounted solidly on the same drive shaft of the motor, except for the balance weight, for which a free rotational motion around the drive shaft in question has been provided in the range required for linear shaking.
  • the basic idea of the system is a crank lever mechanism, in which the performance of the motor is ensured during the use of different shake methods by altering the leverage relations.
  • the leverage relations can be altered so that an orbital motion having the desired radius is generated at the desired rotational speed.
  • the leverage relations are altered in a way to decrease the demands on the motor and to attain the desired accelerations and motion distances.
  • the system has, inter alia, the following advantages:
  • a single-motor construction is achieved when the motor rotates continuously in one direction. Linear motion results by having the motor rotate back and forth within a sector narrow enough not to move the counterweight. This solution requires less space, fewer motor controls, reduced cabling and the like. In addition, the construction requires but one single eccentric and one single mobile plane.
  • the construction is as silent and wear reducing as possible, as the motion of the shake plane being the sum of the rotational motions of the different parts and the construction being free of slack.
  • the driving force for the shaking is provided by the stepping motor (7).
  • a crank assembly (9) with a connecting rod (5) equipped with bearings is solidly mounted on the shaft of the stepping motor.
  • One end of the connecting rod is connected to the shake table (1) through the intermediary of a bearing block (12).
  • a linear actuator (10) locks the Y motion of the system by pushing a lock pin through the Y motion locking part (8) and a balance weight (4). This action prevents any motion of the shake table in the Y direction and any motion of the balance weight during linear shaking.
  • the stepping motor moves into a position such that the crank arm
  • the driving force for the shaking is provided by the stepping motor (7).
  • a crank assembly (9) with a connecting rod (5) equipped with bearings is solidly mounted on the shaft of the stepping motor.
  • One end of the connecting rod is connected to the shake table (1) through the intermediary of a bearing block (12).
  • the stop shoulder (11) in the crank assembly moves against the connecting rod, whereby the axis of the connecting rod pointing towards the shake table starts rotating with a radius of 12.5 mm (in this implementation version), thus entailing the same motion in the shake table mounted on bearings in linear guide bars (6). Any vibrations caused by the shaking are eliminated by the pivoted balance weight

Abstract

L'invention concerne un système vibrant prévu pour générer un mouvement de vibration dans une table vibrante (1), un plan vibrant, une palette vibrante ou analogue, la vibration étant généralement utilisée comme procédé de mélange de systèmes de divers types. Le système génère à la fois une vibration linéaire et une vibration orbitale à l'aide du même moteur pas à pas (7) sans aucune boîte de vitesses séparée ni interrupteur permutateur, les actionneurs (10) de la vibration linéaire et de la vibration orbitale étant ainsi solidement fixés sur le même arbre d'entraînement du moteur (7). Le mouvement rotatif libre dans la plage requise pour la vibration linéaire a été fourni pour un poids d'équilibrage (3).
