Abstract

Abstract An autonomous strip laying device for marking the ground includes a rolling frame supporting a reel of strip to be unwound, a strip unwinding assembly, elements for applying the strip on the ground including an applicator roll, a device for sectioning the strip and an assembly driving the frame and actuating the different devices and the unwinding elements. The assembly unwinding the strip and the elements for applying the strip are, at least during the unwinding and laying of the strip, mutually synchronized in rotation by synchronizing elements.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 170 words
An autonomous device for laying at least one strip for marking a ground, which comprises: a rolling frame for supporting a reel of strip to be unrolled; an unrolling assembly including unrolling means for unrolling the strip; application means including an applicator roller for applying the strip on the ground; a sectioning device for sectioning the strip; a drive assembly for the frame and for actuating different devices and the unrolling means; and at least one synchronization means for synchronizing in rotation said unrolling assembly and said application means with each other, at least at the time of unrolling and laying the strip; a sectioning of the strip taking place with the unrolling assembly and the application means being unsynchronized; said unrolling assembly comprising a fixed axle, a supply roller, an upper traction drum coacting with at least one upper roller-carrying axle, a driver and separator having rollers with projecting portions made of one piece or connected and disposed in alternation from one roller to another with their generatrices intersecting.
Claim 2
Dependent Claim 170 words
An autonomous device for laying at least one strip for marking a ground, which comprises: a rolling frame for supporting a reel of strip to be unrolled; an unrolling assembly including unrolling means for unrolling the strip; application means including an applicator roller for applying the strip on the ground; a sectioning device for sectioning the strip; a drive assembly for the frame and for actuating different devices and the unrolling means; and at least one synchronization means for synchronizing in rotation said unrolling assembly and said application means with each other, at least at the time of unrolling and laying the strip; a sectioning of the strip taking place with the unrolling assembly and the application means being unsynchronized; said unrolling assembly comprising a fixed axle, a supply roller, an upper traction drum coacting with at least one upper roller-carrying axle, a driver and separator having rollers with projecting portions made of one piece or connected and disposed in alternation from one roller to another with their generatrices intersecting.
Claim 3
Dependent Claim 47 words
The device according to claim 1 , further comprising a tensioning roller-jack assembly to tension or untension a belt connecting said unrolling assembly and said application means; the desynchronization between the unrolling assembly and said application means taking place by unclutching, at the same time as cutting.
Claim 4
Dependent Claim 24 words
The device according to claim 1 , wherein the application means comprises at least one lower roller-carrying axle and at least one guide axle.
Claim 5
Dependent Claim 39 words
The device according to claim 1 , wherein the synchronization means comprise an arrangement of belts, of pulleys, or double pulleys; a belt synchronizing said at least one upper roller-carrying axle with said at least one lower roller-carrying axle.
Claim 6
Dependent Claim 15 words
The device according to claim 1 , further comprising straightening means for straightening the strip.
Claim 7
Dependent Claim 20 words
The device according to claim 5 , wherein the straightening means comprise a straightening axle provided with a straightening roller.
Claim 8
Dependent Claim 29 words
The device according to claim 5 , wherein the straightening means comprise at least one guide means for adjusting the straightening, the width and the maintenance of the strip.
Claim 9
Dependent Claim 35 words
The device according to claim 5 , further comprising a spool mounted on a spool-carrying axle provided with at least one gripping means, and guide means facing said gripping means for adjusting the straightening means.
Claim 10
Dependent Claim 90 words
The device according to claim 1 , wherein the sectioning device comprises a transverse blade guided between carrier slides and actuated at its end opposite to a cutting portion by a sectioning jack, and a counter-blade; said transverse blade being disposed perpendicularly to the plane of the strip between the unrolling assembly and the application means, and coacting, for sectioning, with said counter-blade extending over a support parallel to said transverse blade between the upper traction drum of the unrolling assembly and the applicator roller to produce an instantaneous cut.
Claim 11
Dependent Claim 18 words
The device according to claim 9 , wherein the transverse blade and the counter-blade are of quenched steel.
Claim 12
Dependent Claim 73 words
The device according to claim 9 , further comprising a control and display console having a programmable robot for controlling the laying of the strip, and for adjusting the application of the rollers of said at least one upper roller-carrying axle to the strip, against the upper traction drum and the counter-blade; said console comprising a control member permitting selecting between three ways of carrying out the cut, namely: manually, semi-automatically, or automatically.
Claim 13
Dependent Claim 44 words
The device according to claim 1 , wherein the supply roller, the fixed axle and said at least one upper roller-carrying axle are mounted on a pivoting frame, comprised between two flanks, articulated about the upper roller-carrying axle and positioned by an upper jack.
Claim 14
Dependent Claim 37 words
The device according to claim 1 , further comprising a hydraulic bridge connected to a motor for its movement, said motor being also adapted to drive a compressor to supply air under pressure to different actuating members.
