Description
SAFE MATERIAL HANDLING SYSTEM AND METHOD
Technical Field
The invention relates to a safe material handling system and method providing elimination of collision of material with other stacked materials or other objects in the handling environment during material handling operation and increase in handling operation efficiency and occupational safety.
The invention particularly relates to safe material handling system providing effective prevention of material with other materials or objects within the environment during handling of sheet coil like materials from one point to another in production area; industrial environments and defining the objects detected on the handling route or surrounding and increasing efficiency of handling operation and occupational safety and a working method for this system.
Background of the Invention
In industrial environment where material handling is conducted such as material handling area, production area, storage area etc. handling systems called crane are used for handling materials of sheet coil and others with similar various physical features. Material lifting and handling machines called cranes provides handling cargo hung onto rope, chain, and tong like handling members and movement and handling of the lifted material in different directions. Crane and similar material lifting and carrying machines provide handling of material at a position and a speed determined by the user and interval work steps comprising movement processes such as stopping, speeding up and slowing down etc. during the operation are conducted. Particularly, at the companies conducting sheet trading, sheet coil cutting and at enterprises manufacturing sheet , crane machines are commonly used. While cranes use connection members such as rope or chain during cargo lifting and handling operations, holding material is provided by means of carrying members in holding structure called tong.
In the carrying systems used at prior art, detection of materials stacked before in order to carry sheet coil like materials and locate/stack them properly and recording the data if there is stacked material on the location intended to carry the material into matrix order by means of logical addressing are provided. Upon comparison of logical addressing information to the reference table containing material locations, it is determined if there is stacked material in
target location and thus faulty handling is prevented. However, it is not possible to detect the obstacles or external objects on the route through which the material is carried by this method and it is not likely to understand if there is an obstacle or object expected to be present in production area. For that reason, although object detection is provided by current handling systems, it is not understood if the detected object is an object already on the handling route or an obstacle coming onto the route later and this case causes accidents or unnecessary stopping during handling operation and results in delay in work process, time and cost loss.
The patent document numbered JPH0761772A, in the prior art, discloses a handling system providing sheetcoils. Said system comprises ultrasonic sensors located on tong providing handling of the material. Four ultrasonic sensors located on four axis of the crane provides detection of coils placed onto moving axis of the crane. Upon processing of the signals received from ultrasonic sensors, it is understood if there are any sheet coils on the location planned for placement of the carried sheetcoil. In addition, it also discloses providing placement in single or two stage stacking order onto the empty location under the document. Said document does not disclose any application for detection if there are objects on the route where the sheet coil is carried and determination if the detected object is an obstacle or an object required to be on the route.
Another patent document numbered US2013299440A1 in the related art literature discloses a material positioning system providing detection of position of a crane’s cargo and providing data of position to a mapping module. Said system comprises a map receiver module providing mapping of material handling area and transmitting the taken map to the mapping module, labelling scanner providing scanning of the area around the place where crane is located and determining the obstacles and transmitting obstacle data to mapping module. The data obtained by label scanning, material location data in mapping module are combined with map and obstacle data and displayed on a graphic interface accessible by user. Thus, detection of area around and under the material in motion and prevention of probable hitting are aimed. Said document does not disclose anything about detection of not labelled objects or materials, determination if the detected object or material is an obstacle or an object required to be on the route.
As a result, it is needed to develop a safe material handling system providing effective prevention of material with other materials or objects within the environment during handling of sheet coil like materials from one point to another in production area; industrial environments and defining the objects detected on the handling route or surrounding, determination if the material or objects detected on the route are obstacle or an object required to be on the route
and increasing efficiency of handling operation and occupational safety and a working method for the system.
Purpose of the Invention
The present invention relates to a safe handling system and method for such system meeting the needs mentioned above, eliminating potential disadvantages and providing some additional advantages.
Primary purpose of safe handling system and its method of the invention is to provide a safe material handling system and its method providing effective prevention of material with other materials and accidents by means of providing detection of objects and materials on handling route and recognition of detected materials during carrying of materials from one location to another in industrial environments convenient for handling of materials.
Another purpose of the invention is to provide an efficient safe material handling system and its method preventing prevention of hitting and accidents thus preventing delays in handling operation by means of discovering if the materials or objects detected on the handling route are obstacles or the objects expected to be on the route.
A further purpose of the invention is to provide a fast and effective safe material handling system providing prevention of unnecessary stopping or slowing down during handling operation and thus providing reduction in time of operation and cost thereof.
