Control device for a loading device for bulk goods containers
First Claim
1. Control arrangement for a loading device for bulk goods containers, in particular trash vehicle collecting containers with a loading chamber receiving the bulk goods and a motor driven feeding shovel which executes a movement cycle, for feeding the bulk goods from the loading chamber into the bulk goods container, which is separated into sequential movement phases which are initiated during the course of the movement cycle which actuates control members, characterized in that an electronic control device (39) is provided which actuates the control members (33) in dependency from electronic switches (41a, b;
- 43) which react to operating conditions of the loading device, and that the electronic control device (39) is provided with an arrest circuit (FIG.
15) which reacts only to the switch pulse of the next following switch in the movement cycle, after receiving the switch pulse (Je1 '"'"' Je2, Je3, Je4) of a switch (41a, b;
43), and leaves all other remaining switches unaffected so that in the event that one of the remaining switches emits an incorrect switch pulse or signal the arrest circuit assures that the feeding shovel cannot execute an inadmissible movement cycle.

Abstract
A control arrangement for a loading device for bulk goods containers is proposed. The movement cycle of the loading device is controlled by an electronic control device. The control device has an input which is connected to several electric control signal transmitters which at a certain position of the loading device generate a signal. The output of the control device is connected to electric control members which switch on the drive of the loading device for different movement steps thereof. This is achieved by the control device through switching from one control member to another control member when the respective control signal transmitter generates a signal that the movement step of the loading device has occurred in a correct manner. In order to prevent any faulty controls, which occur when the control signal transmitters are not working properly, an arrest circuit is provided which prevents that the control signal transmitter transmits signals to the control device in an incorrect sequence. Consequently, undesired or even dangerous movement steps of the loading device are prevented.
