Abstract
Abstract Machine and service truck assembly for loading, unloading and storing ceramic tiles comprises a loading-unloading machine provided with a vertically mobile head constituted by a plurality of horizontal, parallel projecting brackets which are coplanar and each of which is provided upperly with a motorized roller. The head is arranged for sideways insertion into a truck constituted by a plurality of flat vertical parallel frames provided with horizontal transverse equidistant bars which overall constitute support surfaces, with the brackets inserted between the frames.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
186 words
A machine and service truck assembly for loading, unloading and storing ceramic tiles, comprising: a horizontal frame substantially of L shape in plan, arranged to move vertically on vertical guides; a set of horizontal conveying belts disposed orthogonally on one arm of said L frame and terminating in a belt conveyor system; a set of motorised projecting rollers branching in plan from the other ram of said L frame and having a length approximately equal to the width of the set of conveyor belts, and forming a roller surface, said rollers each having spaces therebetween; a service truck comprising a plurality of vertical adjacent frames each provided with equidistant horizontal cross members, said frames being disposed in planes parallel to said projecting rollers, the distance between adjacent frames being greater than the outer dimension of a projecting roller and the thickness of each frame being less than the spaces between rollers so that the frames can be received in the spaces between rollers; and means for vertically moving said L shaped frame; and means for moving said truck parallel to the axis of said projecting rollers.
Claim 2
Dependent Claim
186 words
A machine and service truck assembly for loading, unloading and storing ceramic tiles, comprising: a horizontal frame substantially of L shape in plan, arranged to move vertically on vertical guides; a set of horizontal conveying belts disposed orthogonally on one arm of said L frame and terminating in a belt conveyor system; a set of motorised projecting rollers branching in plan from the other ram of said L frame and having a length approximately equal to the width of the set of conveyor belts, and forming a roller surface, said rollers each having spaces therebetween; a service truck comprising a plurality of vertical adjacent frames each provided with equidistant horizontal cross members, said frames being disposed in planes parallel to said projecting rollers, the distance between adjacent frames being greater than the outer dimension of a projecting roller and the thickness of each frame being less than the spaces between rollers so that the frames can be received in the spaces between rollers; and means for vertically moving said L shaped frame; and means for moving said truck parallel to the axis of said projecting rollers.
Claim 3
Dependent Claim
85 words
An assembly as claimed in claim 1, wherein said horizontal L shaped frame is essentially constituted by three small carriages each individually slidable on a vertical guide and connected together by two cross members to define said L shaped frame, said carriages being connected respectively to three endless chains disposed parallel to said guides and supported thereby, three sprockets driven by a common self-braking electric motor disposed above said piers, said three chains passing respectively over said three sprockets and being driven by said sprockets.
Claim 4
Dependent Claim
86 words
An assembly as claimed in claim 1, comprising means mounting each roller on said other arm for rotation; a drive sprocket for each roller on an outside of said arm; a chain extending around said sprockets; an electric motor driving said chain; an end of each roller remote from said other arm being supported by a bracket connected to the arm and extending parallel with and beneath its corresponding roller, each bracket having a transverse dimension not greater than the outer dimension of its corresponding roller.
Claim 5
Dependent Claim
21 words
An assembly as claimed in claim 1, wherein each roller comprises a covering of elastic material substantially over its entire length.
Claim 6
Dependent Claim
37 words
An assembly as claimed in claim 1, wherein said set of horizontal conveyor belts disposed on one arm of the L frame is substantially at the same level as the upper generating line of said roller surface.
Claim 7
Dependent Claim
68 words
An assembly as claimed in claim 1, wherein said service truck comprises a platform, flanged wheels on the platform and arranged to run on rails, and above said platform a vertically extending parallelepiped framework within which said plurality of vertical frames are removably disposed with said horizontal cross members disposed parallel to the axes of the wheels, said frame cross members defining a plurality of horizontal loading surfaces.
Claim 8
Dependent Claim
69 words
An assembly as claimed in claim 1, wherein inner opposing faces of the lower and upper cross members of the parallelepiped framework of the service truck comprise comb structures, one at each of said cross members, and each of which includes a plurality of like spacers distributed at a constant pitch, and between each pair of which is defined a passage to receive a vertical frame for upward withdrawal.
Claim 9
Dependent Claim
66 words
An assembly as claimed in claim 1, wherein the means for moving the service truck in a direction parallel to the axes of the rollers of said roller surface comprises a second truck movable on track rails parallel to the axes of the rollers, and on which is disposed a rail section orthogonal to said track rails, said service truck being disposed on said rail section.
