摘要:
A conveyor system comprising a series of buckets (10) supported by entrainment means such as a chain (15A,15B) along a predetermined endless path having straight portions (19,20,21) and at least one internal curve (28C). An individual pivoting arm (12) supports a respective bucket (10) on the chain (15A,15B). Each pivoting arm (12) is pivotally attached to the entrainment means (15A,15B) at a first end in fixed orientation to the chain (15A,15B), and pivotally supports the bucket (10) at the opposite second end. A chain guide (50 or 52) engages the chain (15A,15B) in advance of an internal curve (28C) in the path to cause the buckets (10) to move apart and then allow the second end of the pivoting arm (12) to which the bucket (10) is attached (at 14) to pivot outwardly and the buckets (10) in turn to follow a diverging curved path (27A) of greater radius than the radius of the curve (28C) in the path being transited and thereby space the buckets (10) further apart prior to negotiating the internal curve (28C) in the path than when the buckets (10) are proceeding along a straight portion (19,20,21) of the path.

A tipping mechanism for buckets carried by a conveyor or elevator. Each bucket 28 is attached to a chain 26 by a swing link 29 and each bucket carries a sector shape cam 30. As the buckets are carried around a sprocket 27 the cam 30 contacts a peg 31, so as to cause the bucket to progressively tip and empty. The movement of the buckets back to their horizontal position is fully controlled and is smooth by virtue of the contact between a French curve on the cam 30 and a cam surface 35 of substantially wedge shape located above or below the conveyor or elevator chain.

L'invention a pour objet un dispositif de transport à réceptables et une caméra ayant le chant oblique à l'axe des réceptacles et un système de basculement des réceptacles sur un demi-tour. En se référant à la figure, (8) est la came qui pivote sur un demi-tour, (13) est un des systèmes de déclenchement (pour exemple: qui commandé peut faire basculer la came, avec une languette qui maintiendrait ou désarmerait le système de déclenchement), (10) est le téton de la came qui la maintient à l'horizontal, en coulissant dans une glissière et arrête le basculement de la came sur un demi-tour, (14) est l'orifice qui permet à l'embout de sortir de la glissière, (7) est l'axe solidaire de la came et des réceptacles qui passe à travers un maillon de la chaîne, (15) est une languette à ressort qui empêche le soulèvement de l'embout par l'orifice en cas de non déclenchement du crochet.

Eine Entladestation für ein Pendelbecherwerk, bei dem Pendelbecher (10) an mindestens einem Zugglied (12) um eine horizontale, über ihrem Schwerpunkt liegende Achse (11) drehbar aufgehängt sind, besteht aus einem gestellfest drehbar gelagerten Hebel (17) mit einem im Abstand von der Hebel-Drehachse (18) angeordneten Zapfen (19). Um die Drehbeschleunigung des Pendelbechers (10) beim Kippen zu vergleichmäßigen, ist der Zapfen (19) mit einer an dem Pendelbecher (10) vorgesehenen Klaue (21) in Eingriff bringbar.
摘要:
An apparatus for tipping a bucket (11) carried by a conveyor chain around a circuit to empty the contents thereof at a predetermined location comprising a sprocket (90) mounted concentric with the pivot about which the bucket (11) rotates and fixed for rotation with the bucket (11). The sprocket (90) has a plurality of radially outwardly-extending uniformly spaced-apart projections (90a,...90e) and at least one space on the sprocket (90) defined by the absence of a projection. An elongate rack (95) is positioned adjacent the chain at the bucket tipping position and has sprocket engaging means (96,.,..,101) thereon positioned in engaging alignment with the projections (90a,...,90e) of the sprocket (90) as the bucket (11) passes, thereby to arrest rotation of the bucket while the bucket is in its inverted position to permit the contents to empty entirely.
