BR-102024017319-A2 - DEVICE FOR TRANSPORTING PARTS
Abstract
The present invention presents a system for maintaining a continuous flow of materials on the line, eliminating inventory on the line as well as eliminating packaging, keeping the side line clean. It is a continuous flow assembly line supply system, utilizing advanced manufacturing concepts through the elimination of packaging and the determination of fixed locations for each piece on the Sushi box trays, eliminating the need for the pieces to be shipped with their packaging. The determination of fixed locations allows the operator to know the position of each piece, reducing search time.

Description
FIELD OF APPLICATION [001] The present invention applies to the field of transport and storage. More specifically, the invention provides a continuous flow production line supply cart. FUNDAMENTALS OF THE INVENTION [002] Within the context of transporting and storing parts, especially in large production lines, the organization, optimization, ease, and versatility of the transport method are key to effective production. The transport method chosen by the company responsible for the production line must take into account various characteristics, such as weight, fragility, size, material, risk, and other important characteristics of the elements to be transported. [003] One of the most widely used methods for storing and transporting products on production lines is industrial carts. Known for meeting most of the needs of a production line, they are capable of holding and transporting a wide variety of materials with simple and low-cost technology, in addition to having high durability, reliability and robustness. [004] Despite the aforementioned advantages related to existing market technology, there are still several limitations that hinder the logistics of production lines from being even better in terms of efficiency, optimization, and productivity. Existing models of industrial carts are for generic use and do not utilize the technique of organizing parts in fixed positions, which makes it difficult to find the desired part, and they also present a high-cost traction system. Furthermore, due to the robustness of the equipment, as well as the large volume of elements it accommodates, the parts to be stored and/or transported require extra protection, such as specific packaging, to prevent damage. [005] Thus, the present invention presents an industrial supply car for a continuous flow production line, of the Sushi box type, with a system for organizing parts in specific positions, using advanced manufacturing concepts, thus eliminating the need for packaging. The traction system uses bidirectional maneuvering, allowing the formation of convoys of up to 4 units for each tug. These characteristics influence the cost, weight and optimization of the system, both in the context of its manufacture and utility and in the context of the production line itself. State of the art. [006] Document JP 2007188158 A describes a system consisting of an RFID (Radio Frequency Identification) tag attached to a semi-finished product, transported along a production line, which transmits an identification signal at fixed intervals. A component supply cart moves automatically while following the semi-finished product. In this way, the component supply cart, positioned between a conventional large-scale component supply system using an AGV 8 and the production line, is controlled to minimize the difference in the reception times of the radio waves transmitted by the RFID tag. [007] In the document, the material is made available in a flow-rack close to the point of use, requiring the operator to move the material to the point of application. Whereas in the present invention, the Sushi box rack is attached to the cart being assembled, this keeps the material close to the point of application, avoiding repetitive movement by the operator and thus preventing material loss due to improper handling. [008] In this way, the present invention differs from other documents by presenting a cart with separation in the trays and a dedicated location for each material, that is, the same material will always remain in the same place, thus reducing the operation time, since the operator does not waste time looking for the material in the cart, as it will always be in the same place, in addition to avoiding errors when handling similar materials. SUMMARY OF THE INVENTION [009] The present invention presents a system for maintaining a continuous flow of materials on the line, eliminating stock on the line as well as eliminating packaging, keeping the line side clean. It is a continuous flow assembly line supply system, using advanced manufacturing concepts by eliminating packaging and determining fixed locations for each piece on the Sushi Box cart trays, eliminating the need for the pieces to go with the packaging. The determination of fixed locations allows the operator to know the position of each piece, reducing search time.
