Abstract
A new type of picking wheel is proposed for the golf ball pickers characterized by the fact that has a solid configuration with a rim edge on the periphery of the disc and a solid hub , the picking wheel being made of hard but flexible polyurethane with solid lubricant such as graphite or molybdenum disulfide for reducing the wear and the friction coefficient.
Description
IMPROVEMENTS IN THE GOLF BALL PICKERS
BACKGROUND OF THE INVENTION
The invention relates to the picking wheels or discs used for the golf ball pickers, particularly for golf ball picking machines having a vehicle chassis for example like a gardening tractor and attached in front of it the ball picking mechanism in form of a series of picking discs or wheels on a common shaft rolling directly on the ground.
DESCRIPTION OF THE PRIOR ART
There are known wheel or discs used for golf ball pickers made of different plastic materials like nylon, ABS, polypropylene used to pick the golf balls.
These known wheels ,because of the materials used and because they are generally thick, have the following disadvantages:
a)they are very rigid;
b)they have a high coefficient of friction between the golf ball and them;
1 S c)they do not resist well to abrasion inherent in the golf ball picking process d)they are prone to fracture and brittleness;
e)the retaining process of the golf ball between the wheels is based on peripheral elements in form of fingers or ribs which sometime make the ball to escape outside;
f)they have a complicated form-involving ribs and fingers-making the tooling and the production process expensive;
The author made extensive experiments in terms of form and composition of the presently proposed disc/wheel which resulted in optimum operation eliminating/
reducing the above disadvantages.
SUMMARY OF THE INVENTION
In aim to solve the above disadvantages a disc/wheel for golf ball pickers is proposed characterized by the fact that is involving the following:
a) a solid circular disc possessing a certain flexibility, having an outside diameter, a thickness, an axis of rotation/symmetry a front face and a back face and a periphery; also in the centre of the circular disc being a central hole ,this hole having known means to be fixed to a common shaft such as key notches, flat faces or splines;
b) a hollow solid circular cylinder having an outside diameter equal with the outside diameter of the solid circular disc, a thickness, an axis of rotation/symmetry and a height called hereinafter the edge rim;
c)whereby the edge rim or the hollow solid circular cylinder is rigidized to the solid circular disc in such a way that the hollow solid circular cylinder is applied on the front face of the disc, on the periphery of it and their outside diameters and axes of rotation are coinciding;
d)whereby the edge rim or the solid circular disc and the hollow solid circular cylinder can be made integrally together using the same material either by injection moulding or casting so that both the disc and the cylinder can be considered being the same part;
e) a solid cylindrical hub having a height,a front face and a back face, an axis of rotation and a central hole along the axis of rotation ,this hole having known means to be fixed on the common shaft passing through the hole such as key notch/flat faces splines or similar, the said means having the same configuration with the means to be fixed on the common shaft of the above said circular disc , the height of the hub being slightly bigger than the diameter of the known standard golf ball;
f)whereby the solid cylindrical hub being rigidized to the circular disc with solid circular cylinder in such a way that their axes are coinciding and the back face of the solid cylindrical hub is applied on the front face of the solid circular disc;
g)whereby the solid circular disc, the hollow circular cylinder and the solid cylindrical hub rigidized as mentioned above is forming an assembly hereinafter called "picking wheel";
h) whereby on the said common shaft being put through their hubs, one after another a number of picking wheels ,these picking wheels being placed in sequence,or in series one after another in such a way that all the time, everywhere along the said common shaft the front face of the cylindrical hub of one picking wheel is placed/pressed against the back face of the circular discs of the subsequent/ nearby picking wheel so that we have a stack of them on the said common shaft;
I)whereby the picking wheels pressed one in the back of other in a stack are kept together by known fixing means such as nuts ,wedges or splines so that the said picking wheels are not loose on the said common shaft;
j)whereby a standard golf ball by the virtue of the above mentioned flexibility of the circular disc can be squeezed between two subsequent circular discs or two picking wheels but cannot escape from it because of the said edge rim;
The proposed picking wheel as described above being made of a material comprising/involving the following:
a) A casting mould designed in a known way having a configuration to generate by casting/pouring, the form of the picking wheel as described above;
b) Unroyal L-325 Adiprene Polyurethane 100 parts by weight in liquid form;
c) MOCA(4,4' Methylnebis(2-chloroaniline) 26 parts by weight in granular form;
d) Solid lubricant-in powder/flakes form, either graphite or molybdenum disulphide 0.5 % of the weight combined of the Adiprene and MOCA;
e)whereby the said polyurethane ,MOCA and solid lubricant are mixed together at 167 degrees Fahrenheit till the solid lubricant and moca are dispersed-dissolved uniformly in the mass of liquid polyurethane,then cast in the said mould, then cured for one hour at 212 degrees Fahrenheit.
The way of operation of the described picl~ing wheels is as follows:
The assembly made of the stacked picking wheels on a common shaft is free rolling on the ground by being pushed by the tractor type chassis; the golf balls are scattered on the ground and when the picking wheels are passing over them, because of the weight of the stacked picking wheels assembly, the rim edges of the picking wheels are pushed aside enough for the golf ball to enter in the space between the 2 succesive circular discs; then the balls are centrifugated by the Coriolis force on the periphery of the discs but retained by the rim edges and brought to a point where the balls are simply extracted by a stationary finger expelling them out from the discs and deliveredlguided to a subsequent centralizing collecting element part of the mobile golf ball picking machine;the process being possible because of the flexibility of the picking wheels-the material being polyurethane based which essentially had a hard rubber consistency.
The advantages of implementing this proposed picking wheel are as follows:
a) increased abrasion resistance inherent to polyurethanes;
b)increased flexibility improving the fatigue resistance and the picking process;
c)reduced friction coefl'lcient facilitating the centrifugation of the golf ball by the Coriolis forces generated in the rolling/picking process;
d)increased wear life because of reduced friction coefficient and polyurethane base;
e)ease of fabrication because of the simple configuration and hence simple mould configuration BRIEF DESCRIPTION OF THE DRAWING
