Abstract

Conventionally, loading and unloading pallets occurred in a factory like environment, wherein traditional systems were used for stacking pallets vertically for retrieval thereof. However, these pallets arrive from a roller conveyer and such set-ups are purely based on the concept of storage purpose and lack in palletizing and depalletizing in effective manner. Embodiments of the present disclosure provide pallet loading and unloading apparatus for automated objects manipulation, wherein pallet(s) from a forklift jack arrives on a linear slider assembly for movement of pallet from loading area to manipulating area using two double-sided cylinders associated thereof. Rollers comprised in apparatus provide flexibility to linear slider to slide freely on top. Manipulator performs palletizing and depalletizing as applicable. During depalletizing, empty pallet is slide down using actuator(s) and guided pins and pushed back to bottom rollers which is below a L-channel and is pushed out towards bottom ramp at pallet exit area.

First claim

We claim:

1. An apparatus for automated objects manipulation to and from pallets, the apparatus comprising:
a mobile base;
a plurality of pallet receivers mounted on one end of the mobile base, wherein each of the plurality of pallet receivers are configured to accommodate a pallet;
a linear slider having a first double sided piston at a first end and a second double sided piston at a second end of the linear slider, wherein the first end and the second end of the linear slider are opposite to each other, wherein a first pallet receiver accommodates a first pallet in a first area, wherein the first pallet is locked by the linear slider, the first double sided piston and the second double sided piston, and wherein the linear slider is configured to slide the first pallet from the first area to a second area of a second pallet receiver such that a second pallet is configured to occupy the first area;
a plurality of sensors mounted on the mobile base; and
a robotic manipulator mounted on other end of the mobile base, wherein the robotic manipulator is in communication with the plurality of sensors for (i) navigating to a desired position and manipulating one or more objects placed on the first pallet and (ii) loading the manipulated one or more objects to a desired location, and wherein when the first pallet is empty, the first pallet is indexed to a bottom layer of the mobile base and the second pallet is moved to the second area, using a first piston pin of the first double sided piston and a second piston pin of the second double sided piston of the linear slider.

2. The apparatus as claimed in claim 1 , wherein the robotic manipulator is in communication with plurality of sensors for (i) navigating to a desired location and manipulating one or more objects placed inside the second pallet and (ii) loading the manipulated one or more objects to another desired location.

3. The apparatus as claimed in claim 1 , wherein the apparatus is configured to dynamically move from a first position to a second position within the desired location based on space occupied by the one or more objects being manipulated.

4. The apparatus as claimed in claim 3 , wherein the apparatus dynamically moves from the first position to the second position by a specific length obtained from a loading planner.

5. The apparatus as claimed in claim 1 , wherein the first area and the second area are one of (i) a pallet loading or unloading area or (ii) an object manipulating area comprised in a pallet.

6. A method for manipulating objects by a pallet loading and unloading apparatus, the method comprising:
receiving, by a first pallet receiver of the pallet loading and unloading apparatus, a first pallet in a first area;
locking, the first pallet, using (i) a first double sided piston positioned at a first end of a linear slider of the pallet loading and unloading apparatus and (ii) a second double sided piston positioned at a second end of the linear slider, wherein the first end and the second end of the linear slider are opposite to each other;
sliding, via the linear slider, the first pallet from the first area to a second area of a second pallet receiver; and
manipulating, via a robotic manipulator of the pallet loading and unloading apparatus, one or more objects placed on the first pallet for loading the manipulated one or more objects to a desired location.

7. The method as claimed in claim 6 , wherein the one or more objects are manipulated by the robotic manipulator of the pallet loading and unloading apparatus based on navigation information and manipulating information obtained from a plurality of sensors mounted on the pallet loading and unloading apparatus.

8. The method as claimed in claim 6 , wherein when the first pallet is slid to the second area, the first pallet receiver is configured to accommodate a second pallet in the first area.

9. The method as claimed in claim 8 , wherein the robotic manipulator is in communication with plurality of sensors for (i) navigating to a desired location and manipulating one or more objects placed inside the second pallet and (ii) loading the manipulated one or more objects to a desired location.

10. The method as claimed in claim 6 , further comprising upon determining that the first pallet is empty, automatically indexing the first pallet to a bottom layer of the mobile base and sliding the second pallet from the first area to the second area, using a first piston pin of the first double sided piston and a second piston pin of the second double sided piston of the linear slider.

11. The method as claimed in claim 6 , further comprising dynamically moving of the pallet loading and unloading apparatus, from a first position to a second position by a specific length obtained from a loading planner, wherein the pallet loading and unloading apparatus dynamically moves from the first position to the second position within the desired location based on space occupied by the one or more objects being manipulated.
