CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY
[0001] The present application claims no priority from any of the patent application(s).
TECHNICAL FIELD
[0002] The present invention relates to the field of an article loading system. More particularly, the present invention relates to a double parallelogram mechanism for the article loading system.
BACKGROUND
[0003] This section is intended to introduce the reader to various aspects of art, which may be related to various aspects of the present disclosure that are described or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure. Accordingly, it should be understood that these statements in this background section are to be read in this light, and not as admissions of prior art. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.
[0004] Loading platforms for lifting or displacing a product are widely used in various industrial applications. Further, a linkage mechanism for driving such loading platforms is designed and developed considering the factors like location, space, power source, and type of application. There are various industrial segments like logistic industry, warehouse material handling, material feeding in manufacturing industry, automated assembly lines, and many others where the loading platform with linkage mechanism is used. Additionally, there are various configurations of the linkage mechanism are formed with respect to the specific operational requirement. These linkage mechanisms are fixedly or detachably attached to the loading platform carrying the product. Moreover, the operation of such linkage mechanism is performed by an actuator which can be hydraulically, or pneumatically, or electrically powered.
[0005] In one of the configurations of conventional linkage mechanism, a parallelogram linkage mechanism is used for driving the loading platform carrying the product. Further, the parallelogram linkage mechanism is also known as a four-bar mechanism. In the combination of the conventional parallelogram mechanism with the loading platform, one link of the linkage mechanism is attached to the loading platform, and the opposite like of the same is attached to an actuator. Further, the actuator operates the parallelogram linkage mechanism causing movement of the loading platform from initial position to final position forming a circular trajectory. More specifically, the conventional mechanism only allows the aligning of the loading platform with a space where the product is to be unloaded.
[0006] In such conventional mechanism, the movement of the loading platform is restricted only up to a circular motion. Also, the circular motion achieved by the conventional mechanism fails to facilitate the unloading operation of the product from the loading platform. More specifically, the conventional parallelogram linkage mechanism fails to facilitate a linear motion of the loading platform followed after completion of the circular motion. Additionally, the conventional linkage mechanisms include heavier links which affects operational efficiency and maintenance of the entire mechanism. Also, the coupling of the actuator with any one of the links of the conventional linkage mechanism is complex and causes failure during transfer of power from the actuator to the parallelogram linkage mechanism.
[0007] In light of the above stated discussion, there exists a need of an improved parallelogram linkage mechanism for driving a loading platform to overcome at least one of the above stated problems.

The article loading system (100) as claimed in claim 1, wherein the pinion (108) is rotated in a clockwise direction and an anti-clockwise direction by the actuator (112), wherein the pinion (108) rotates in the clockwise direction on a forward movement (F) of the actuator (112), wherein the pinion (108) rotates in the anti-clockwise direction on a rearward movement (R) of the actuator (112), wherein the rotation of the pinion (108) in the clockwise direction and the anti-clockwise direction facilitates the cranking motion of the crank pin (106c) in the clockwise and anti-clockwise direction.
12. The article loading system (100) as claimed in claim 11, wherein the actuator (112) comprises a rack (118), wherein the rack (118) is configured to engage with the pinion (108), wherein the forward movement (F) and the rearward movement (R) of the actuator (112) is transferred by the rack (118) to the pinion (108), wherein the pinion (108) is rotated in the clockwise and the anti-clockwise direction with the forward movement (F) and the rearward movement (R) respectively.
13. The article loading system (100) as claimed in claim 1, wherein the actuator (112) may include at least one of hydraulic actuator, pneumatic actuator, electrical actuator, or any combination thereof.
14. The article loading system (100) as claimed in claim 1, wherein the tray (110) comprises a conical ring (120) at front portion (110a), wherein the conical ring (120) is adapted to be placed securely against an conical opening (114a) of the hollow tube (114), wherein the linear motion of the tray (110) facilitates concentric securing of the conical ring (120) with the axis (116) of the hollow tube (114) at the conical opening (114a).
15. The article loading system (100) as claimed in claim 1, wherein a ramming actuator is provided at the rear portion of the tray (110), wherein the rear portion of the tray (110) is provided with a stopper, wherein the stopper is configured to hold the article placed within the tray (110) from rear side, wherein the ramming actuator is configured to load the article to the hollow tube (114) by displacing the stopper.
