4. DESCRIPTION.

Technical field of invention:
Present invention in general relates to design and implement an automated glycerin soap cutting machine and in particular to develop a mechanism to enhance the productivity of glycerin soap production unit.

Prior art:
Productivity is an important parameter to measure the performance or efficiency of any plant. In India, there are many soap producing industries, which produces variety of soaps in different sizes and types. However, there are few companies which produce glycerin soaps. The production of glycerin soap is crucial, since it contains glycerin as a major ingredient, which makes it transparent. The presence of glycerin makes the processes such as cutting and handling of soaps complicated that gives rise to many defects such as edge damage, crosscuts, less surface finish, cutting marks on soap surface, as a result the percentage rejection in these units is relatively high, hence needs special purpose machines.
Machine of this type has been disclosed in patent no. 164400 granted on June 15, 1875 in the name of Charles F. Sieber at United States Patent office. Such machines are having fixed cutter-frame provided with a series of adjustable cross-wires and inter mediate cutting -frame sliding vertically in grooved ways on the fixed cutting-frame. Due to the use of wires and two frames for cutting such machines deals with the problem of regular tightening of wires, breaking of wires and uneven shapes of cut soaps because of loose wires. The loosening of wires also may results into crosscuts, weight and size variations among the cut pieces and also cutting marks on the cut surface.
Another soap cutting machine is disclosed in United Patent series no. 273176, granted on February 27, 1883 in the name of W. Dean Smith of Boston, Massachusetts. This machine also makes use of cutting wires to cut the soap, and thus deals with the same issues as discussed with the above invention. Also, in this machine the entire base along with the support section is having grooved ways and the complete base is needed to be moved towards the cutting wires, this is done manually which required more human power and leads to jerky operation resulting unsmooth soap surface. This machine is also having a restriction of cutting material in only cubical blocks.
Such type of soap cutting operation on a soap cutting machine is also disclosed in a patent no. 852190 of United States patent office granted on April 30, 1907 in the name of Hugh William McEwen of Chicago, Illinois. In his machine, cutting wires are used for cutting the soaps, thus the problems discussed with the first inventions remains same here. In addition the feeding of soap bar on the cutting wires damages the surface of soaps causing wire marks on the surface. The surface of soap also gets damaged when its falls down after cutting. This machine is particularly useful for cutting a long soap bar of circular cross-section into small pieces only and not for the soap bar having elliptical cross-section.

STATEMENT:
Accordingly following invention provides a design and implementation of an automated glycerin soap cutting machine. Soap cutting machine is used to cut the soaps, as per the required weight or size. Soap cutting is a shearing operation, in which the small pieces of required weight or size are sheared off from the long soap bar. The soap bar (12) which is to be cut into small pieces as per the required size and weight is kept on the input conveyor (11), as the input conveyor (11) starts moving, the soap bar (12) is feed between the pusher (9) and the blade assembly (2). The soap bar (12) touches the stopper (35) provided at the end of input conveyor (11) and gets stopped. A proximity sensor (21) is provided at the stopper end to detect the presence of soap bar (12) thus, as the bar is detected at the stopper end, the input conveyor (11) stops and the pusher (9) moves forward as it is connected to the piston rod end of the hydraulic cylinder (18). The pusher (9) carries the soap bar (12) with it towards the blade assembly (2), and then the blades (26) start cutting the soap bar (12) till the end of the stroke. At the end of stroke, the pusher pushes the cut soap tablets on the tilt plate (13). Thus the soap tablets falls on the output conveyor (14) due to gravity. At the end of the forward stoke, the presence of pusher is detected by another proximity sensor (19) and thus the forward stroke stops and the return stroke of pusher starts. At the end of reverse stroke, the pusher is detected by the third proximity sensor (20) which makes the blade cleaning assembly move down and then up, cleaning the accumulated soap material from the blade surface with the help of Teflon flat (34). At the same time, the presence of pusher detected by the proximity sensor (19) also starts the input conveyor (11) again and thus the awaited soap bar on the input conveyor (11) again enters between the pusher and blade assembly and the process cycle is repeated. As the solenoid operated direction control valve and three proximity sensors (19) (20) (21) are used, the human interference and the dry running of the machine is avoided, and provides a safe alternative with high productivity. The preferred embodiment mainly comprises of blade assembly, pusher, hydraulic cylinder, blade cleaning assembly, pneumatic cylinders, proximity sensors, table, hydraulic power pack, linear bearings, conveyor, tilt plate, bracket, hex nut, guide pins, frame, Teflon flat, rubber strip, etc.

Working:-
The working of machine can be seen clearly with the help of given drawings. The soap bar (12) which is to be cut into small pieces as per the required size and weight is kept on the input conveyor (11), As the input conveyor (11) starts moving, the soap bar (12) is fed between the pusher (9) and the blade assembly (2). The soap bar (9) touches the stopper (35) provided at the end of input conveyor (11) and gets stopped. A proximity sensor (21) is provided at the stopper end to detect the presence of soap bar (12) thus, as the bar is detected at the stopper end, the input conveyor (11) stops and the pusher (9) moves forward as it is connected to the piston rod end of the hydraulic cylinder (18). The pusher (9) carries the soap bar (12) with it towards the blade assembly (2), and then the blades (26) start penetrating into the soap (12) till the end of the stroke. At the end of stroke, the pusher pushes the cut soap tablets on the tilt plate (13). Thus, the soap tablets falls on the output conveyor (14) due to gravity. At the end of the forward stoke, the presence of pusher is detected by another proximity sensor (19) and thus the forward stroke stops and the return stroke of pusher starts. At the end of reverse stroke, the pusher is detected by the third proximity sensor (20) which makes the blade cleaning assembly (4) to move down and then up, cleaning the accumulated soap material from the blade surface with the help of Teflon flat (34). At the same time, the presence of pusher detected by the proximity sensor (19) also starts the input conveyor (11) again and thus the awaited soap bar on the input conveyor (11) enters between the pusher and blade assembly and the process cycle is repeated. As the solenoid operated direction control valve and three proximity sensors (19) (20) (21) are used, the human interference and the dry running of the machine is avoided, and provides a safe alternative with high productivity.
