O 42 O 20 4 I8 0 3 a I l l l 4 6 2 A o o STAND AND TRANSFER DEVICE SUMMARY OF THE INVENTION My invention comprises a vertical stand provided with a horizontal arm carrying a vertical adjustment screw which can be raised or lowered. A vertical hydraulic cylinder is secured to the stand and is provided with a piston extending out of the top end. A table top is secured to the top end of the piston and is tiltable thereon. Valve means secured to the cylinder, when actuated, raise the piston and table. When the table receives a load and the valve is properly controlled, the table is forced downward by the action of gravity. As the table contacts the screw, it is tilted.
In one application of my invention, loads can be transferred between conveyors of different heights or levels, thus eliminating the necessity of having workers lift and transfer heavy filled containers and the like.
BRIEF DESCRIPTION OF THE DRAWINGS In the drawings:
FIG. I is a side view of my invention in lowered position;
FIG. 2 is a similar view showing my invention in raised position;
FIG. 3 is a cross section taken along line 3-3 in FIG. 1;
FIG. 4 is a perspective view of my invention in use; and
FIG. 5 is a top view of my invention.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS This invention relates to automatic machinery and, more particularly, to a support stand for packing cases and containers which can be adjusted and controlled in rate of speed and movement with the application of air pressure.
The present invention can be used in fruit and vegetable packing houses to eliminate the manpower ordinarily needed to lift and transfer heavy fllled containers onto a moving belt or other suitable surface.
There is a growing need for a product of this type in this industry. It fills a long felt need in a convenient, effective manner and at a cost within the budget of the ultimate user. Inherent advantages over possible competing items are thus available at minimal cost which should rapidly gain acceptance.
Existing facilities may be utilized to minimize tooling and production costs. Materials may be varied to suit such facilities. Standardization of components will minimize inventory costs, whereby costs can be held at low levels with moderate production runs.
This invention operates by means of air pressure and gravity. The table on which the case is placed can be positioned as required and tilted to load and unload. The stand is simply constructed and can be economically manufactured. Its introduction to produce packing houses should create an immediate and sustained response in the form of volume sales over a long term period, with reduction in labor costs.
Referring now to FIGS. I--5, a vertical hollow post I0 extends upwardly from horizontal base 12 and contains a vertical hollow support 14 freely slidable up and down in the hollow chamber 16 in the post. Post 10 has, at its upper end, a horizontally extending arm 16 with a vertical adjustment screw 18 at the free end of the arm and manually adjustable up and down.
A horizontal table 20 having a plurality of parallel horizontal freely rotatable rollers 22 as a bottle receptacle 24 in which the top end of support 14 is disposed and sevured. Receptacle 24 has a horizontal prong 26 with a stop 28 whereby one end ofa chain 30 can be secured slidably on the prong. The other end of the chain is secured to post 10. Table 10 has a vertical pin 42 alignable with screw 18.
A vertical hydraulic cylinder 32 is secured to one side of the post 10 and is rovided with an u wardly extending iston 34 secured pivota ly at 36 to the ta le 20. Cylinder 3 is connected via a manually adjustable throttling valve 44 and hose 46 to a foot operated control valve 38 and from the valve 38 to a source ofhydraulic fluid.
When no foot pressure is exerted on valve 38 hydraulic pressure raises the table to a horizontal position as shown in FIG. 2 with chain 30 limiting the upward travel.
When the foot pressure is exerted, the table is lowered by gravity until its pin strikes the screw and tilts as shown in FIG. 1
Goods from an endless belt conveyor 40 can be loaded onto the table when in raised position whereby the table can be lowered and the goods pushed off onto a lower conveyor.
While I have described my invention with particular reference to the drawings such is not to be considered as limiting its actual scope.
Having thus described this invention what I claim as new is:
l. A stand and transfer device comprising: A vertical hollow post; a vertical member slidable up and down within said post; load support means pivotally secured to the top end of said member; fluid means including a vertically oriented cylinder with piston means movable therein; means for pivotally securing said piston means to said load support means to vertically move same upon operation of said fluid means; a horizontal arm attached to and extending outward from the top end of said post; vertically adjustable means mounted on said arm adjacent the free end thereof; means mounted on said load sup port means vertically aligned and engageable with said adjustable means to pivot said load support means to remove a load therefrom upon lowering of said load support means.
2. A stand and transfer device as defined in claim 1 wherein said load support means includes conveyor means.
3. A stand and transfer device as defined in claim 1 wherein said vertical adjustable means comprises a screw.
4. A stand and transfer device as defined in claim 1 and further including flexible means operative with said fluid means to limit upward movement of said load support means.
5. A stand and transfer device as defined in claim 1 and further including control means located adjacent the base of said post for controlling said fluid means.
