Technical Field

The invention relates to an object transportation system for transporting objects and for transferring objects from one section to another section, which enables mechanisms and units to be moved on a machine or plant along a long or short linear or non-linear line.

Known State of Art

Linear bearing systems are used to move or transport an object, product or goods from one point to another. Linear bearing systems are among the systems with a wide range of applications. These systems are sometimes used for a bearing system, sometimes integrated into a product transport carriage and used for linear motion on a long line. They are equipped with different techniques and mechanisms depending on the area and zone to be used.

Currently used bearing and motion systems have a multi-part structure, consisting of multiple sets of balls and bearings or a lubrication system. In most cases, they are capable of moving in one axis.

During the patent research for linear bearing, motion systems and product transportation systems;

A US patent with the number US8635960B2 was found. This application relates to a deep groove ball bearing having a structure in which an omnidirectionally rotatable ball (the main ball) is protruding and suitable for application to a support table, a turntable, and the like, used for carrying or placing objects.

In a US patent US20120068035A, the free ball bearing includes a retaining ball pressing ring, the retaining ball pressing ring including a substantially cylindrical pressing member disposed toward a base end in an inner cavity between the hemispherical recessed surface and the main ball; the retaining ball pressing ring is moved from a pressing position to a rest position along the center axis of the unit by the ring movement mechanism, the pressing member comprising a structure that restricts or prevents rotation of a plurality of retaining balls by pressing multiple retaining balls while the retaining ball pressing ring is in the pressing position.

The field of the invention with Application No. US6786318B1 relates to apparatus for facilitating the movement of heavy structures and, more particularly, to a low-friction transfer apparatus to be incorporated with the working surface of a table on which the heavy object is designed to rest.

As a result, the existence of the above problems and the lack of an existing solution necessitated a development in the relevant technical field.

Objective of the Invention

Detailed Description of Invention

Figure-1 illustrates the general perspective view of the Object Transportation System (1000). The system can be positioned and designed according to the needs of all kinds of facilities, machines, assemblies, units and different spaces for different purposes. The h and hi lengths of the system can vary and it is possible to make the desired length according to the area to be used. Likewise, the Object Transportation System (1000) is not limited to linear movement on the same line. As can be seen in the figure, it can have semi-circular radius lines as well as S and zigzag lines. The Object Transportation System (1000) can be used not only in automation systems in industry or in continuous flow systems, but also in different stores and sales markets. For example, in a hardware store, a sales center selling electrical systems and companets, it is a feature that can meet the needs of transferring objects and products from long-distance points to different points.

The object transportation system (1000) comprises a slide assembly (2100) having a modular line (2600) configuration that allows the formation of linear, circular, semi-circular and curved lines, and at least one carriage (3600) that travels on linear and non-linear curved and semi-circular lines on said slide assembly (2100). However; providing maneuverability of the carriage (3600) on circular, semi-circular and curved lines, an execution pressure device (3640) having tension springs (3642) that apply continuous pressure to the wheel according to the circular structure of the track on curved lines (2700), and an execution pressure device (3640) having a wide-angle execution element (3620) that is brought into contact with the track edge (2121 ) on curved lines by means of said tension springs (3642).

The slide assembly (2100) is preferably a rectangular structure consisting of 4 linear slides (2110) and 4 semi-circular slides (2120). However, it is not limited to 4 pieces, but it is possible to have multiple or monolithic structures. Two of the linear slides (2110) are positioned in the x-axis direction and the other two in the y-axis direction. Semi-circular slides (2120) are connected to the linear slides (2110) at the transition from x-axis to y- axis.

The slide pulley drive element (2200) is the structure that gives the first drive to the slide drive pulley (2300) and is supported by a servo motor. The slide drive pulley (2300) is the structure that is driven by the slide pulley drive element (2200) and makes a circular motion, and this circular motion is transmitted to the slide idler pulleys (2400).

The slide idler pulley (2400), of which there are 3, is the structure that enables the circular motion transmitted from the slide drive pulley (2300) by the sled motion transmitter (2500) to be continuously rotated in a closed loop.

The sled motion transmitter (2500) is the structure that provides motion transmission by connecting the slide drive pulley (2300) and the slide idler pulleys (2400) by winding them together at a certain tension and contains a belt made of rubber material. The carriage (3600) is a movable structure that moves stably on the slide assembly (2100). The carriage body (3610) consists of a wide angle executive element (3620), a narrow angle executive element (3630), an execution pressure assembly (3640) and an execution fitting (3650). The wide-angle executive element (3620) is 2 in number and is positioned at the base of the carriage body (3610), with a certain distance between them. The narrow-angle executive element (3630) is 2 in number and has a certain distance between it and the wide-angle executive elements (3620) on the y-axis. The narrow-angle executive elements (3630) and the wide-angle executive elements (3620) are engaged with the slide assembly (2100), ensuring contact of the slide assembly (2100), and are engaged with the slide assembly (2100), allowing it to move along the slide assembly (2100). When changing direction from the x-axis to the y-axis or from the y-axis to the x- axis, i.e. when changing direction from the linear slide (2110) to the semi-circular slide (2120), the narrow-angle executive element (3630) engages the linear slide (2110) on the y- or x-axis in a narrow arc. In order to engage the linear slide (2110) on the y-axis or x- axis by drawing a wide arc when the wide-angle executive elements (3620) change direction from the x-axis to the y-axis or from the y-axis to the x-axis, that is, when changing direction from the linear slide (2110) to the semi-circular slide (2120), a pressing force perpendicular to the slide assembly (2100) is continuously applied by the execution pressure assembly (3640). By means of this pressing force, the wide-angled executive elements (3620) are permanently connected to the slide assembly (2100). The execution pressure assembly (3640) is a structure which continuously applies a pressing force perpendicular to the slide assembly (2100) to the wide angle execution elements (3620). The executive compression assembly (3640) consists of a pressure fitting (3641 ), a tension spring (3642), a tension adjusting member (3643) and a tension transmission element (3644). The pressure fitting (3641 ) connects the execution pressure assembly (3640) to the carriage body (3610) in the y-axis and also provides a fulcrum for the pressure force. The tension spring (3642) is a 2-piece structure, which is connected to the pressure fitting (3641 ) at one end and to the tension transmission element (3644) at the other end, and which creates tension force for the wide-angle executive elements (3620). The tension adjusting element (3643) is connected to the tension spring (3642) via the pressure fitting (3641 ) and adjusts the stiffness of the tension spring (3642). Tension transmission element (3644), 2 pieces, located concentrically with the wide- angle executive elements (3620) and transmitting the tension force generated by the tension spring (3642) to the wide-angle executive elements (3620). Execution fitting (3650) is mounted to the carriage body (3610) from the y-axis and is the structure that provides the connection of the sled motion transmitter (2500). Tension springs (3642) apply continuous pressure on the wheels in curved lines (2700) according to the circular structure of the line. This constant forced pressure allows the curved line to be gripped and the carriage to move in a rigid and stable manner without slideding.

Thanks to the compression adjustment of the springs used in the system, it is possible to adjust the slide stiffness in accordance with the desired load. However; thanks to the pressure of the springs in the system, the slide carriage has the ability to move in different radiuses on the same line.

On the other hand, thanks to the system's specially made slides and precise slide wheels, the slide carriage can reach a speed of 3000 rpm.

Figures 10, 11 and 12 illustrate representative top views of the object transportation system (100) as it is moved along a long open line with no closed line. The carriage (3600) does not have to be operated on a closed line. On the contrary, it is possible to operate it on open long or short lines. Likewise, the said carriage (3600) can be driven directly on the linear slide (2110) of the slide assembly (2100) without the need for an external drive system and can be driven on the long line with its own drive element.
