摘要:
A method and apparatus for crushing and sorting cans to collect waste cans in an optimal weight-to-volume ratio. The can crushing and sorting method adapted to crush and sort cans by use of a can crushing device, into which the cans are sequentially supplied, involves an object determining step for determining, by a proximity sensor (124) installed at a can supply unit (120), whether or not an object is supplied, and then whether or not the supplied object is a can or a foreign matter, a can supplying step for if it is determined that the supplied object is a can, opening an opening/closing plate (122) installed at the can supply unit, thereby supplying the can into a crushing/sorting/discharging unit (30), and a can crushing/sorting/discharging step for crushing the supplied can by a crushing plate (35) installed in the crushing/sorting/discharging unit (30), sorting the crushed can using an electromagnetic force applied to the crushing plate by electromagnets (34) mounted to the crushing plate (35), in accordance with the material of the can, and then discharging the sorted can.

The improved upper magnetic plate for anchoring molds, is constituted by a body made of steel with high magnetic permeability in which recessed seats (3) are provided for accommodating coils (4) adapted to generate an attracting magnetic field, the improvement consisting in that the coils (4) are constituted by turns of wire (5) made of a material such as a fluorocarbon resin perfluor alkoxy (PFA) and wrapped by a peripheral containment lapping (7) made of an adhesive tape which has a vitreous base; the coils (4) are arranged in the corresponding recessed seats (3) and are locked therein by means of a thermosetting silicone containing filling material (8) which is initially inserted in the plastic and malleable state; the seats can be closed in an upward region with plates (9) made of diamagnetic material.

Poinçonneuse à commande électromagnétique dotée d'un moteur de poussée à commande électromagnétique comprenant un enroulement à solénoïdes refroidis par ventilateur ainsi qu'un enduit mobile monté dans un emplacement élevé agencé pour (a) isoler le circuit magnétique de l'outillage de découpage à colonnes, (b) isoler le chauffage électrique de la bobine de l'outillage, (c) positionner la bobine et l'enduit à un emplacement élevé où ils sont facilement accessibles, (d) permettre un réglage pratique de: la longueur de la course, la hauteur "ouverte" et la hauteur "fermée", (e) permettre un réglage facile de la position de l'enduit, (f) assurer un accès par quatre voies à l'outillage, (g) libérer la partie inférieure de la poinçonneuse, (h) permettre le montage côte à côte au même emplacement élevé des moteurs à commande électromagnétique multiples, (i) permettre d'empiler des moteurs à commande électromagnétique multiples à des niveaux d'élévation multiples les uns sur les autres, (j) ménager un emplacement de plate-forme élevé où il est possible d'installer des robots ou des actuateurs pneumatiques de manipulation de matières et/ou de manipulation d'outils, (k) produire un moteur de poussée à commande électromagnétique amovible et interchangeable parmi des blocs à colonne multiples. Une pièce polaire navette destinée à amplifier l'énergie disponible s'étend vers le haut jusque dans l'ouverture de l'enroulement et elle est montée mobile avec une sollicitation élastique vers le haut afin de permettre à la pièce polaire navette de se déplacer vers le bas de manière à réduire le choc, le bruit et les vibrations de l'impact lorsqu'elle est frappée par l'enduit descendant lorsque s'achève sa course de travail. On a prévu des supports anti-glissement pour les roulements à bille et les cages des bagues des roulements à bille portant l'outil mobile afin d'empêcher le glissement vers le bas de ces bagues et de leur cage lorsque l'outil mobil effectue un poinçonnage contre la matière d'usinage.

Beschrieben wird ein Foulard mit möglichst geringem Flottenauftrag. Hierzu wird eine Rakel (12) an den Umfang einer Umschlingungswalze (1) mittels abstoßender Magnetkraft gehalten. Die Rakel hat nebeneinander eine Vielzahl von Aussparungen, die als Durchlässe für die Flotte wirken. Durch die abstoßende Magnetkraft werden eventuelle Unrundheiten der Umschlingungswalze ausgeglichen, so daß die Rakel über ihre gesamte Länge gleichförmig am Umfang der Walze anliegt.

The production and operation of high-performance press-rollers having the usual design always entails considerable production and maintenance costs to set and maintain the pressure in the working slit of the roller arrangement at a constant value over the length of the roller. The new roller arrangement avoids the undesirable warping of the rollers. The roller arrangement has a magnetic circuit that includes both rollers. The magnetic circuit consists of a cylindrical magnetic core (4), several poles (5) axially distributed on the magnetic core, a cylindrical exciter (3) and control windings (14) arranged between said poles, a magnetic shell that encloses the whole circumference of one roller and is made of two parts separated by a ring-shaped secondary air gap (11), and a continuous magnetic shell in the axial direction arranged at the outer circumference of the other roller. When used to process webs of material in the textile, paper, plastic and metallurgical industries, this electromagnetic roller arrangement achieves high quality standards with a high productivity. The solution provided by the invention is shown on the figure above.

A magnetic calender comprises a pair of rotatable parallel rolls (1, 2) and an electromagnet provided with two pole pieces (6, 7) extending parallel to the rolls (1, 2) and joined to a common base (5) through a plurality of magnetic cores (8) having an arrangement which is specularly symmetrical with respect to both the transverse mid-plane and the longitudinal mid-plane of the calender. A coil (9) and a control solenoid (10) located adjacent to the relevant pole piece (6, 7) are wound around each of said cores (8), and the intensity of the current circulating in the coil (9) is controlled by an adjusting unit (11) which is in turn controlled by a control unit (12) which receives and processes the magnetic flux reading carried out by the control solenoid (10).

An electromagnetically-driven punch press having an electromagnetic drive thrust motor comprising a fan-cooled solenoid winding and movable armature mounted in an elevated location arranged for (a) isolating the magnetic circuit from the die set tooling, (b) isolating electrical heating of the coil from the tooling, (c) positioning the coil and armature in an elevated location where they are readily accessible, (d) enabling convenient adjustment of: stroke length, 'open' height and 'shut' height, (e) enabling easy adjustment of the armature position, (f) providing four-way access to the tooling, (g) freeing the bottom of the punch press, (h) enabling multiple electromagnetic drive motors to be mounted side-by-side at the same elevated location, (i) enabling multiple electromagnetic drive motors to be stacked at multiple elevational levels one-above-another, (j) providing an elevated platform location where material-handling and/or tool-handling robots or pneumatic actuators can be installed, (k) providing an electromagnetic drive thrust motor which is removable and interchangeable among multiple die sets. A shuttle pole-piece for boosting available energy extends upwardly into the winding opening and is movably mounted with a resilient upward bias for permitting the shuttle pole-piece to move downwardly for reducing impact shock, noise and vibration upon being struck by the downwardly-moving armature upon completion of its work stroke. There are anti-skid supports for the ball bearings and ball cages of the ball-bearing bushings which carry the movable tool for preventing downward skidding of these balls and their cages when the moving tool punches down against the work material. Adjustable resilient cushioning arrests tool travel for minimizing 'tool whip' and tool wear at the end of the work stroke.
