Abstract
A press has a framework (1) which supports a pressure plate (3). The pressure plate is attached to a fluid operated ram assembly (4) by means of gimbals (20) so that the pressure plate (3) may adopt different angular attitudes relative to the load being compressed. In order to prevent the ram assembly (4) being subjected to stress the ram assembly (4) is mounted on the framework (1) by means of gimbals (18). The freedom of movement of the pressure plate (3) laterally is restrained by opposed pins (26) which engage loosely in slots (27) on the frame and stops (28) on the opposed pins. The press may be used to compress a palletized load, such as cardboard box blanks, prior to banding.
Claims5
A press for the compression of a load comprising a frame (1) defining a compression area, a pressure member (3) movable relative to the load for compressing the load located within the compression area, means mounting said pressure member (3) to be able during compression to tilt about a first horizontal axis and to tilt about a second horizontal axis substantially perpendicular to said first horizontal axis so as to adopt different angular positions relative to the load whereby irregularity in the shape of the load may be accommodated, and guide means (26, 27, 28) for guiding the pressure member (3) during said movement, said guide means (26, 27) including, at each of two opposed sides of the pressure member, a projection portion (26) and a portion (27) receiving said projection portion, one of said portions being elongate and provided on the frame (1), and the other of said portions being on the pressure member (3).
A press for the compression of a load comprising a frame defining a compression area, a pressure member movable relative to the load for compressing the load located within the compression area, the pressure member during compression, being able to adopt different angular positions relative to the load so as to accommodate irregularity in the shape of the load, and guide means for guiding the pressure member during said movement characterised in that the guide means comprises two projection pins projecting one from each of two opposed sides of the pressure member, which engage loosely in respective elongate slots in guide plates on the frame and which restrain lateral movement of the pressure member in a first general direction and rotational movement of the pressure member about the axis of movement of the pressure member, and an inwardly curved plate on each of the projection pins which restrain lateral movement of the pressure member in the other generally transverse direction and rotational movement of the pressure plate about a substantially horizontal axis.
