DESCRIPTION:
BRIEF SUMMARY
Applicant hereby claims priority under 35 USC 120 and 365(c), of PCT Application No. PCT/EP 85/00052, filed Feb. 15, 1985.
The invention relates to a device for emptying containers, especially for emptying refuse bins into collecting containers, in which a lifting and tipping device, or a tipping device, driven by at least one pressure medium motor is provided with a lifting and tipping frame, or with a tipping frame, that holds the container to be emptied, wherein the pressure medium motor or motors is/are controlled by means of a pressure medium valve inserted in the pressure medium-power circuit, which pressure medium valve is connected directly or indirectly with its actuating mechanism to a control circuit that contains a time switch determining the timed valve control of the valve for the sequence of movement.
A device of this kind is known from DE-A No. 27 21 059, in which a pressure switch disposed laterally with respect to the tipper and intended for hand-actuation is provided as the element starting up the emptying process. It is necessary first of all to position the container to be emptied on the tipping frame, or lifting and tipping frame, or at least approximately to bring the container into a suitable position, and then to actuate the hand switch starting up the automatic sequence of the emptying process. In practice it is inevitable that the containers brought towards or placed on the lifting and tipping frame, or the tipping frame, will sometimes not be gripped correctly by this. The device known from DE-A No. 27 21 059 therefore carries an increased risk of accidents.
Furthermore, DE-PS No. 1,028,935 discloses a dustbin tipper in which the control valve for the pressure medium motor is provided with a hand-actuating element which, when the valve has been brought into the actuating position for the pressure medium motor, may be inserted behind a retaining bolt. A disconnecting lever, likewise arranged in the pressure medium-power circuit, is allocated to this retaining bolt in such a manner that it pushes the hand-actuating element of the control valve behind the retaining bolt forward and, to return the control valve to its initial position, releases it as soon as the load of compressed air on the disconnecting lever has reached a corresponding level. The disconnecting lever itself is controlled from an overflow valve which is actuated by the pivot axle of the tipping device, or lifting and tipping device. If it is desirable to provide for the container to be emptied to be vibrated when it is in its tipping-in position, then a suitable actuating cam could be provided on the pivot axle of the tipping device, or lifting and tipping device, for the overflow valve, and a flow throttle could be provided in the feed line to the disconnecting lever. By this means, a repeated tipping in and tilting back movement is caused when the tipping device, or lifting and tipping device, is towards the end of its tipping range, until the disconnecting lever is loaded sufficiently by pressure medium to release the hand-actuating element from the retaining bolt, so that the control valve is able to return to its initial position. This known device requires, firstly, pneumatic pressure medium-power circuits, and above all requires the emptying process to be initiated by hand actuation of the control valve, and the hand-actuated element of the control valve to be locked.
These two known devices also make it essential, when operation is carried out by a single individual, that either the container to be emptied is hooked onto appropriate devices of the lifting and tipping frame, or tipping frame, or that the operator simultaneously keeps hold of the container to be emptied and operates the control valve, which frequently results in the container being incorrectly held on the lifting and tipping frame, or tipping frame, and/or in incorrect operation of the control valve. To ensure that the container to be emptied is safely held on the lifting and tipping frame, or tipping frame, and to ensure reliable operation o
