Abstract: A piston and cylinder arrangement for opening and closing entrance or exit doors or both in a milking compartment of a fully automated milking system. The piston and cylinder arrangement comprises an elongated cylinder having two pistons connected in tandem to an elongated piston rod. The cylinder is hermetically divided into two cylindrical portions each containing one of the pistons. The piston acts against a liquid in one portion and in the other portion the piston is actuated by pneumatic pressure. The piston rod is extended through the end of the cylinder and is connected to open and close an entrance door. The cylindrical portion containing the liquid has the liquid on both sides of the piston connected by a check-valve and a by-pass valve. To block movement of the pistons, the by-pass valve is retained in a closed position by pneumatic pressure from a supply of pressurized gas for actuating the piston in the pneumatic side of the cylinder. The by-pass valve is a sliding valve urged into an open position by a compression spring when the valve is not closed by pneumatic pressure. Both the by-pass valve and the check valve are disposed external to the cylindrical housing.

Abstract translation: 一种用于在全自动挤奶系统的挤奶室中打开和关闭入口或出口门或两者的活塞和气缸装置。 活塞和气缸装置包括具有串联连接到细长活塞杆的两个活塞的细长气缸。 气缸被气密地分成两个圆柱形部分，每一个都包含一个活塞。 活塞在一部分中作用在液体上，而在另一部分中，活塞由气动压力致动。 活塞杆延伸穿过气缸的端部并连接以打开和关闭入口门。 容纳液体的圆筒部分通过止回阀和旁通阀连接活塞两侧的液体。 为了阻止活塞的运动，旁通阀通过来自用于致动气缸的气动侧中的活塞的加压气体的气动压力保持在关闭位置。 旁通阀是当阀未被气压关闭时通过压缩弹簧推动到打开位置的滑阀。 旁通阀和止回阀均设置在圆柱形壳体的外部。

Abstract: An apparatus for automatically milking animals, is provided with a milking robot which includes a robot arm that carries teat cups, each teat cup being carried in its own housing in a supporting element in the robot arm. When the teat cups are in an inoperative position, the openings on their upper sides are shielded by the supporting element. Each robot arm portion comprises a plurality of housings, one for each teat cup. Piston and cylinder members are disposed in each housing to move the teat cups from their shielded inoperative position to an open operative position under the teats of the animal to be milked and then upwardly to connect the teat cups to the teats of the animal to be milked. Thereafter the supporting element is lowered and the teat cups which remain on the teats are connected thereto only by flexible members. When the milking of each udder quarter is about completed, each teat cup is pulled against a shoe disposed to receive it in its individual housing by a piston and cylinder device in the housing. Placement of the teat cups on the animal's teats is controlled by a computer guided by two cameras mounted on the supporting element which are pointed towards the animal's teats in different angular directions and which include at least one infrared sensitive camera.
