Definitions

  • the invention relates to a movement device, in particular a movement device that is associable with a conveying apparatus for conveying products or articles and is arranged for moving and adjusting, for example, the position of side guides that act as an abutment along a movement path of the aforesaid products.
  • the conveying apparatus is, for example, an air conveying apparatus for empty plastic containers, a rolling shutter conveying apparatus for empty and full plastic or glass containers, a conveyor belt for bundles and boxes.
  • the empty container made of plastics typically a bottle
  • the bottle has an elongated body of tubular shape, of any section, for example circular, oval, square, etc., and an end portion with a decreasing section, called the neck, provided with an annular ridge .
  • the conveying apparatus comprises a pair of supporting guides arranged along the movement path to engage with the annular ridge of the bottle, which thus hangs on and is supported by said supporting guides and can slide longitudinally along the guides .
  • the conveying apparatus further comprises air conveying apparatuses that emit jets of pressurised air in such a manner as to advance the bottle along the movement path.
  • the conveying apparatus includes a pair of lateral abutting guides that are parallel to the supporting guides and are arranged at a lower vertical height to ensure correct positioning and transverse alignment of the bottle during advancing.
  • Such guides are at a distance from one another that is little greater than a transverse dimension of the body of the bottle, in such a manner that the bottle, when inserted between the two guides, is preventing from oscillating transversely during advancing.
  • a device for moving a supporting guide comprising a pneumatic actuator arranged transversely to the guide and provided with a piston provided with a stem the free end of which is fixed to the guide.
  • a further movement device which is structurally and functionally shaped liked the preceding one, is fixed to a further guide in such a manner that the pair of movement devices, which are opposite and aligned on one another, is able to vary the distance between the two guides .
  • These devices are further used to move the lateral abutting guides and adjusting a reciprocal distance thereof in function of the dimensions of the body of the bottle.
  • a drawback of such devices is that they enable the guides to be positioned exclusively in two positions, corresponding substantially to the beginning and end-stroke configuration of the piston. In this manner, the guides can be arranged at a distance that can have only two values and consequently such guides are able to receive only bottles having two preset sizes.
  • a further movement device comprising two pneumatic actuators arranged in succession transversely to the abutting guide that ensure that the guide is positioned in three distinct positions.
  • a drawback of this device is that it is relatively complex and thus has rather high purchase, assembly and maintenance costs .
  • a further drawback of this device is that the number of positions that the guide can assume still remains limited. Further, such positions are extremely stiff and are not susceptible to any adjustment.
  • a further movement device comprising a linear electric actuator fixed to a guide and arranged for moving this guide in a plurality of different positions.
  • a drawback of this device is the high cost of the linear electric actuator.
  • each electric actuator needs an electronic control system and this technical solution is thus very expensive.
  • using electric devices requires suitable and costly electrical insulation systems and it is not recommended for certain applications, for example in the food industry.
  • the nut screw is provided with two series of radial fins that are arranged alongside one another and are angularly staggered, shaped in such a way as to be pushed by the linear actuators acting along a direction that is transverse to the longitudinal axis.
  • the linear actuators comprise two pairs of pneumatic actuators that are opposite one another with respect to the nut screw; each pair of actuators acts on the two series of fins to rotate the nut screw according to a respective rotation direction.
  • the aforesaid device enables an object to be moved linearly (for example a supporting guide or a lateral abutting guide) in a great number of different positions, nevertheless, it does not enable an initial or reference position of said object to be defined that is, for example, necessary for running an automatic guide-size change procedure in an air- conveying apparatuses plant.
  • this movement device is significant because of the opposite arrangement of the linear actuators .
  • An object of the invention is to improve movement devices, in particular movement devices that are associable with product or article conveying apparatuses and are arranged for moving abutting and/or supporting guides of the aforesaid products.
  • a further object of the invention is to obtain a movement device that enables an object to be moved linearly, for example an abutting guide or support, in a great number of different positions and an initial or reference position of said object to be defined with precision.
  • Another object is to make a movement device that is simple and cheap to make, having precise and reliable operation and very compact and reduced dimensions.
  • a device for moving an object linearly, in particular a guide for products in a conveying apparatus, according to claim 1.
  • a movement device provided with a movement element that is movable along a longitudinal axis in a large number of positions, with an end of said element an object to be moved being associable, in particular an abutting guide or supporting guide of an air conveying apparatus for conveying empty containers, or of a rolling shutter conveying apparatus for empty and full plastic or glass containers, or of a belt conveying apparatus for bundles and boxes .
  • the movement element that is movable along the longitudinal axis according to consecutive steps that have a preset value driven by the linear actuator means, comprising for example pneumatic cylinders, having a constant and defined stroke.
  • the reciprocating movement of the linear actuator means is in fact transformed by fin means of nut screw means in a rotation by constant and consecutive angular leads of the latter.
  • the movement element is engaged with the nut screw means by threaded coupling.
  • the movement element further comprises and end provided with first stopping means arranged for abutting on second stopping means of the nut screw means and locking in a defined initial reference position the movement element.
  • first stopping means and the second stopping means when abutting, prevent further movement of the movement element along the longitudinal axis in an advancing direction.
  • the initial position of the movement element is defined precisely and can be assumed as a reference position for the subsequent positioning of the movement element.
  • the linear actuator means comprises a pair of actuators that are alongside and suitable for rotating the nut screw means according to a rotation direction and a pair of further actuators that are alongside and suitable for rotating said nut screw means according to a further rotation direction opposite the rotation direction.
  • the pair of actuators and the pair of further actuators are housed inside respective seats made in the casing and are substantially superimposed, in particular opposite and specular to a plane passing through the longitudinal axis and parallel to a traverse driving direction of said actuators.
  • the actuators are grouped compactly on a single side with respect to the nut screw means, enabling the overall space requirement and dimensions of the casing and of the entire movement device to be reduced.
  • a conveying apparatus comprising at least one movement device of the first aspect of the invention and according to claim 10. Owing to this aspect of the invention, it is possible to obtain a conveying apparatus for containers provided with abutting and/or supporting guides that are moveable in a large number of positions starting from a defined and precise initial reference position such as to interact with a great number of sizes of containers.
  • a guide can in fact be connected that is movable together with the movement element along a direction that is transverse to an advancing direction of the containers along the conveying apparatus. The guide is moved along the transverse direction according to consecutive steps having a preset value.

Abstract

L'invention concerne un dispositif permettant de déplacer un objet de manière linéaire (81, 82, 83, 84; 91, 92; 201, 202) et comprenant un élément mobile (2), qui peut être associé à l'objet (81, 82, 83, 84; 91, 92; 201, 202) et qui présente une partie filetée (22) pouvant coopérer avec un moyen à vis-écrou (3), et un moyen d'actionnement linéaire (4, 5, 6, 7) agissant le long d'une première direction (A1) transversale à un axe longitudinal (B) de l'élément mobile (2) de façon à faire tourner le moyen à vis-écrou (3) selon des avances angulaires consécutives (a) et à déplacer l'élément mobile (2) le long de l'axe longitudinal (B). L'élément mobile (2) comprend une extrémité (23) dotée d'un premier moyen d'arrêt (24) conçu pour buter contre un second moyen d'arrêt (31) du moyen à vis-écrou (3) et bloquer l'élément mobile (2) dans une position initiale définie (P), ceci empêchant ledit élément mobile (2) de se déplacer davantage le long de l'axe longitudinal (B) dans une direction d'avance (C1, C2).
