Description
Background of the Invention
1. Field Of The Invention
This invention relates to automated picking devices for picking fruit and more particularly, to an automated picking device for picking large fruit with stems such as oranges, apples and the like.
2. Background Of The Invention
The use of automated machinery in farming has resulted in high crop yields and minimum labor costs and has resulted in low cost fruit and vegetables products to be available throughout the world. The prior art has successfully automated the planting, irrigation, fertilization and the application of insecticides to various types of crops. Although the aforementioned procedures have been highly automated in the farming industry, the task of picking or removing fruit from the tree has heretofore not been successfully automated for many types of fruit and vegetables crops. Once the crop is manually picked, the farming industry has automated the processing of fruits and vegetables for transportation or for packaging for retail sales.
The task of removing fruit or vegetables from a tree or plant has heretofore not been totally resolved by the prior art due a number of problems existing in the removal process. First, the fruit must be removed in an automated fashion without damage to the fruit or vegetable. Secondly, the fruit must be removed without damage to the tree or plant producing the fruit or vegetable. Third, the automated picking apparatus must be of such a character as to be extremely mobile enabling the automated machinery or apparatus to remove fruit or vegetables located or distributed about the various positions of the tree or plant. Although the automated picking devices of the prior art have been able to successfully remove fruit or vegetables from a plant or tree without damage to the fruit or vegetable or without damage to the plant or tree, the apparatuses have been overly complex and bulky. Accordingly, these automated devices have not obtained the mobility required for the rapid removable of fruit or vegetables from a tree or plant in an automated process. Furthermore, many of these devices have not been successful in picking or removing substantially all of the fruit or vegetables from the tree or plant due to the lack of mobility of the apparatus. Accordingly, the fruit or vegetables remaining on the plant or tree must be picked or removed in a manual fashion, thus adding to the labor costs of producing the fruit or vegetable to market.

It should be appreciated by those skilled in the art that the above dimensions are by was of example and that numerous variations in materials and dimensions may be resorted to without departing from the scope of the invention. Furthermore, it should be appreciated by those skilled in the art that the above dimensions should be modified based on the desired fruit 11 to be picked by the apparatus 10.
As shown in FIG. 4 the first and second array of picking arms 131 and 132 extend radially outwardly from the rotatable member 100 with the plurality of picking arms 130 being in a parallel relationship defining a space 148 between each of the plurality of picking arms 130. Preferably, the space 148 between each of the plurality of picking arms 130 is less than the diameter of the fruit 11.
A first and a second retaining plate 151 and 152 are secured to the picking arms 130 adjacent the first and second end walls 111 and 112 of the rotatable member 100 for retaining the fruit 11 therebetween. Preferably, the first and second retaining plates 151 and 152 are constructed of a durable, transparent polymeric material. The transparency the first and second retaining plates 151 and 152 will not obstruct the vision of an operator.
FIGS. 10-15 illustrate the rotation of the first and second array of picking arms 131 and 132 about the shaft 44. FIG. 10 illustrates the apparatus 10 moved by the coupling boom 16 in proximity to the tree 12 with the first array of picking arms 131 located adjacent to the fruit 11 on the tree 12.
FIG. 11 illustrates a partial counterclockwise rotation of the rotating member 100 relative to FIG. 10 whereby the fruit 11 enters the pathway 145 to enter the retaining region 146 to entrap the fruit 11 within the retaining region 146. The stem 11A of the fruit 11 extend within the spaces 148 between adjacent one of the plurality of picking arms 130 within the extracting portion 142. The retaining portion 143 retains the picked fruit 11 within the retaining region 146 defined by the extracting portion 142 and the retaining portion 143.
FIG. 12 illustrates a partial counterclockwise rotation of the rotating member 100 relative to FIG. 11 wherein the extracting portion 142 of the plurality of picking arms 130 removing the fruit 11 from the tree 12 by the force of rotation of the rotating member 100. The rotation of the rotating member 100 results in the extracting portion 142 severing and removing the fruit 11 from the tree 12. The removed fruit 11 is retained within the retaining region 146 now defined solely by the extracting portion 142 by action of gravity.
FIG. 13 illustrates a partial counterclockwise rotation of the rotating member 100 relative to FIG. 13 wherein the rotational position of the rotatable member 100 results in the action of gravity initially moving the picked fruit 11 from the retaining region 146 along the transfer portion 141. Concomitantly therewith, the second array of picking arms 132 are entrapping fruit 11 within the retaining region 146A in an identical manner as explained with reference to FIG. 11.
FIG. 14 illustrates a partial counterclockwise rotation of the rotating member 100 relative to FIG. 13 wherein the rotational position of the rotatable member 100 results in the action of gravity moving the picked fruit 11 from the retaining region 146 along the transfer portion 141. Concomitantly therewith, the second array of picking arms 132 extract and remove the fruit 11 from the tree 12 by the force of rotation of the rotating member 100 in an identical manner as explained with reference to FIG. 11.
FIG. 15 illustrates a partial counterclockwise rotation of the rotating member 100 relative to FIG. 15 wherein the rotational position of the rotatable member 100 results in the action of gravity migrating the picked fruit 11 along the transfer portion 141. The picked fruit 11 migrates through the aperture 121 in the rotating member 100 and through the input opening 78 of the collector 60 to enter the collector volume 76. It should be appreciated that continued rotation of the rotatable member 100 results in the fruit 11 picked by the second array of picking arms 132 moving through the aperture 122 in the rotating member 100 and through the input opening 78 of the collector 60 for entering the collector volume 76.
After the fruit 11 enters the collector volume 76, the rotation of the auger 50 moves the fruit 11 to the discharge aperture 88. The fruit 11 is discharged from the collector 60 through the discharge aperture 88 and the void 115 defined by the bracket 115 into the chute 32 for transfer to the volume 30 of the trailer 24.
The present invention provide an apparatus which is light-weight and may be mounted on a coupling boom of conventional design for use with a mobile vehicle. The apparatus may be controlled and manipulated by an operator within a mobile vehicle and automatically transfers picked fruit to the mobile vehicle. The apparatus provides a simple, low cost reliable and efficient solution for the fruit picking art.
