1,255,192. Conveying shrimps. MACHINEFABRIEK B. & S. BEDRIJVEN V. D. WOERDT N.V. 12 March, 1969 [14 March, 1968], No. 13005/69. Heading A2U. [Also in Divisions B2 and B8] Apparatus for sorting shrimps on a conveyer belt 1 comprises a stop with converging walls (7), (8), Fig. 3 (not shown) one of which may be parallel to the direction of conveyance. The downstream end of the stop is open whereby pieces of shrimp and straight shrimps may pass directly through the stop whereas curved shrimp are held by the stop and are released in timed relation upon upward movement of the stop. A plate 11 positioned in the stop ensures that shrimps are released by the stop when it is raised. In a further embodiment, Fig. 4 (not shown) a gripper (20), (22) is positioned upstream of the stop and a rotary brush 27 with a peripheral recess 28 is located downstream of the stop. The recess 28 is synchronised with the gripper such that pieces of shrimp, straight shrimps and incorrectly orientated shrimps, i.e. shrimps travelling head first which advance into the stop beyond the reach of the gripper, are brushed from the conveyer whereas those shrimps which are correctly orientated, i.e. heads trailing, are received in the stop and then gripped by the gripper to be released when the stop is raised and in timed relation with the recess 28 to pass through said recess. In a further embodiment, Fig. 6 (not shown) two stops (44), (45) are mounted on a yoke (43) with their narrow ends adjacent each other and with a gripper (46) therebetween. The arrangement being such that pieces of shrimp and straight shrimps pass through the stops and are subsequently removed from the conveyer, whereas correctly orientated curved shrimps, i.e. head trailing, are stop by the stop 44 and then released as the stop is raised and incorrectly orientated shrimps, i.e. head leading, have their heads gripped by the gripper (46) whereupon the stops and the gripper are raised, turned through 180‹ and then lowered back to the conveyer to release the now correctly orientated shrimp.

WOERDT N.V. 1969年3月12日[1968年3月14日]，第13005/69号。标题A2U。 [也在B2和B8区中]用于在传送带1上对虾进行分选的设备包括具有汇聚壁（7），（8），图3（未示出）的挡块，其中一个可以平行于输送方向。塞子的下游端是敞开的，从而虾片和直虾片可以直接通过塞子，而弯曲的虾则被塞子保持住，并在塞子向上运动时以定时关系释放。定位在止动件中的板11确保虾在举起时被止动件释放。在另一实施例中，图4（未示出）的抓具（20），（22）位于止动件的上游，而具有外围凹口28的旋转刷27位于止动件的下游。凹部28与抓具同步，使得虾，直虾和不正确取向的虾的碎片，即先行前进的虾前进到超出抓具范围的止挡位置，从传送带上刷去，而正确取向的那些虾当头部抬起并且与凹部28成定时关系穿过所述凹部时，即，头部的尾部被接收在止挡中，然后被抓具夹持以被释放。在另一实施例中，图6（未示出）将两个挡块（44），（45）安装在轭架（43）上，它们的窄端彼此相邻并且在其间具有抓取器（46）。这样的布置使得虾片和直虾片穿过挡块并随后从输送机中移出，而正确定向的弯曲虾，即头部拖尾，被挡块44挡住，然后在挡块被抬起并错误定向时释放虾（即头顶）的头部被抓爪（46）抓紧，随即停止并抬起抓爪，转过180°，然后放回传送带，以释放正确定向的虾。
