という問題があつた。 However, during the loading operation of garbage, during the raking operation by the raking plate B, between the raking plate B and the inner wall of the input box 2,
In addition, if a problem occurs such as a state in which dust is caught between the pushing plate A and the scraping plate B during the pushing operation by the pushing plate A, the conventional sequence control of the contact point The worker had no choice but to judge each movement of the upper plate B while monitoring it 24/7. Furthermore, in order to resolve this problem, the operator must perform a predetermined operation, which is extremely troublesome. This is a big problem in that it significantly reduces work efficiency, as it is necessary to collect garbage from a wide range of areas within a limited time, and while speedy garbage collection work is desired. It was hot. Furthermore, when a worker performs a loading operation, there is a risk that the pushing plate A and the lifting plate B may malfunction due to an erroneous operation, and as a result, the two plates A and B collide with each other. Similarly, if a worker incorrectly operates the operation order of storage box 1 and input box 2 during the discharge operation, it may cause damage to the garbage truck.
There was also the possibility that this could lead to personal injury. Therefore, the present applicant has proposed sequence control of contacts that executes a corrective sequence control operation that can automatically determine and eliminate the above-mentioned problems (Japanese Patent Application Laid-Open No.
-100719). However, in the sequence control described above, since processing is performed using contact points, there is a problem in that failures are likely to occur and the reliability of the device itself is significantly reduced.

Effects of the Invention According to the present invention, during the garbage loading operation, a situation in which garbage is caught between the scraping plate and the inner wall of the input box and between the pushing plate and the scraping plate does not occur. Even if a malfunction occurs, the operation of the pushing plate and scraping plate is controlled so that the malfunction is automatically determined and resolved, so there is no need for the worker to monitor the operation of the two plates. Since there is no need to perform any operations to resolve the above-mentioned problems, the worker can concentrate on collecting the garbage into the dumping box, and the work can be done quickly, greatly improving work efficiency and covering a wide area within a limited time. Local garbage collection can be realized. Further, even if the operator makes a mistake during the loading operation, it is possible to prevent the pushing plate and the scraping plate from operating outside of the predetermined order, and the two plates will not collide. Similarly, even if the operating order of the storage box and input box is incorrectly operated during the ejection operation, it can be prevented from operating, making it possible to prevent damage and personal injury, thereby greatly improving safety. Moreover, in the present invention, since the processing is performed by non-contact microcomputer control, breakdowns are less likely to occur and the reliability of the device itself is greatly improved.
