Automatic waste material handling/transportation system in industry Introduction: In Industries ( esp. in material processing workshops ), a lot of waste material will be produced. Although this material may be recycled/reused, a major concern in this regard is the handling process that is employed for transporting the materials from the processing location to the storage area. In most of the cases this is done manually and sometimes by using machines like trolleys e.t.c. But in big workshops many kilos of material is to be handled per day and requires definite material handling path. The below discussed handling system, we believe may reduce handling path and also eliminates (to the maximum extent) human involvement. Basic working of the system: The automatic handling system consists of a tunnel shaped passage through which a slider (having space for holding the material) slides. Sliding is carried by suitable guides provided in the underside of the passage. The passage is usually inclined to the shop floor to permit the material to be transmitted to a higher elevation, which then drops into the storage area. passage Conical basin Guide

Th he workm men collecct the wasstes from their macchines annd disposee the sam me into the t conicaal basin arranged at the side of thhe wall. When W thee level off the wasste reach hes a certtain limitt, a sensoor placed in the baasin autom matically switches on the syystem. Th he slide and a valve mechaniism invollved in thhis system m is show wn in fig22. As shoown the sllide has rectangula r ar slots onn both toop and boottom facces whichh assist iin collectting as well w as disposal d o of waste material. m There iss an undeer plate which w alsoo slides along a witth the slidder up to o the spacce where the passaage openns (see fig g3). Wheen the slide reachees the mechanica m ally operaated valvve (providded to thhe passage), the vaalve platee automattically oppens thus allowingg the wastte to f alll into the slide. Thhe slide iss a cabin shaped structure s which haas enoughh space to o hold thhe waste. When thhe slide passes thee valve thhe valve plate p autoomaticallyy closes tthus non permittinng waste (if any) to t fall thrrough the passage. By this w way the slide s colleects the waste w from m different conicaal basins and a finallly transpoorts to thee storage area. a

9 System helps in clean maintenance of the layout. 9 Confusion free workspace. Requirements: It is required to estimate the cost incurred in installing the system and compare this cost with the cost incurred by manual system (involving ordinary handling system of trolleys e.t.c.). Any other limitations is to be evaluated by experienced personals. Prototype: The prototype of similar system will be developed and brought at the time of contest with suitable charts (for explaining the system clearly).
