Description

Autonomous tape laying device

The present invention relates to the field of marking floors, in particular pavements and parking areas, by means of marking strips and has for its object an autonomous device for laying such strips.

Currently, the horizontal marking of parking areas, as well as the provisional marking of pavements, in particular of temporary traffic lanes on pavements under construction, are generally carried out by means of strips, possibly self-adhesive, applied with a contribution of heat and pressure. The positioning of the strips is generally carried out manually by prior cutting, then application to the ground, possibly with an addition of heat and additional pressure by means of an appropriate device. For the application of adhesive strips, prior detachment protective film on their adhesive side is necessary, partially complicating the installation work and resulting in a corresponding loss of time. In addition, the manual installation of these strips, which are relatively heavy, usually requires at least two operators and is relatively painful

It has been proposed, by FR-A-2 674 874, an autonomous device for applying self-adhesive tapes constituted by a chassis supporting a means of unwinding tapes, by a roll for applying the tape on the ground, by a device for transferring the tape from the unwinding means to the application roller, by means for peeling off and recovering the protective film from the adhesive surface, by a device for cutting the tape and by a drive assembly of the chassis and of the various devices and means for unwinding, detaching, recovering and sectioning the tape to be bonded. Furthermore, the utility certificate FR-A-2 723 753 discloses an autonomous device for applying adhesive strips, in particular for marking floors, characterized in that it comprises an articulated rolling chassis, the front part of which carries the roll of strip to be unwound, the strip unwinding assembly, the sectioning device t and the means of applying the strip to the ground, so that the unwinding and application assembly can be oriented independently of the rear part of the chassis.

The marking of floors in prefabricated strips is currently evolving, both in terms of adhesives and even strip structures 2 que 1 pose The constantly improving performance of adhesives means that we are currently witnessing a return to directly bonded tapes to the detriment of self-adhesive tapes which require more complex machines, therefore more expensive and more difficult to use and to maintain The ever increasing requirements in terms of speed of application and quality of marking mean that the machines currently available on the market are no longer suitable or even completely obsolete.

The object of the present invention is to provide an autonomous device for laying prefabricated strips, in particular for marking soils, allowing much higher application speeds and therefore a significant reduction in the time during which the road sections under construction or under construction. renovation are blocked For information purposes, and without any limitation being involved here, a tape application device according to the present invention can reach up to 4 km / h for continuous tapes, a speed never before damage in progress and laying of prefabricated strips In addition, an opening to road traffic is possible as soon as the marking is finished and this, whether the marking is temporary or permanent Another advantage of the device of the present invention is that it provides at the same time time a quality of marking (straightness) and a comfort of application largely superior to those of known machines The present invention ap our subject an autonomous device for laying strips, in particular for marking floors, essentially constituted by a rolling chassis for supporting a reel of strip to be unrolled, said reel being mounted on a reel-carrying axis provided with at least one means clamping, by a strip unwinding assembly, by a means of applying the strip to the ground comprising an applicator roller, by a strip cutting device and by a chassis drive and actuation assembly different devices and means of unwinding, characterized in that said strip unwinding assembly and said strip application means are, at least at the time of unwinding and laying of the strip, synchronized in rotation with one another by at least one synchronization means The synchronization means (s) used in the present invention consist (s) of an arrangement of belt (s), pouch (s) and / or double pulley (s) (s) or the like

The tape unwinding assembly is constituted by a fixed axis, a supply roller, an upper traction drum cooperating with at least one upper roller-carrying axis, driver and separator, the rollers of which are produced in the form of rollers or rollers with spikes or with projecting parts, these spikes 3 or projecting parts being produced in the mass or attached and staggered from one roller or roller to the other with intersection of their generatrices.

In a preferred embodiment, the device according to the invention further comprises a means for straightening the strip, for example, in the form of a straightening axis provided with a straightening roller. This straightening means is then parallel to the unwinding assembly and provided with one or more guide means making it possible to adjust the straightening, the width and the holding of the strip. The adjustment of the straightening means is preferably carried out by means of the above-mentioned guide means or means, opposite the means or means for clamping the spool pin. In particular, it can be provided that the adjustment of the guide means or means of the straightening means is carried out in such a way that the strip is slightly stretched on the straightening axis of the straightening means.

As regards the sectioning of the strip to be bonded, this is achieved by a sectioning device making it possible to make so-called "on the fly" cuts.

A cut is said to be "on the fly" when this is done instantly without interrupting the movement of the strip to be cut.

The cutting device of the present invention comprises a transverse blade made of hardened steel of a well defined hardness.

Said blade slides, for its cutting, between guide slide holders while being actuated, at its end opposite to the cutting edge, by a cutting cylinder. The sectioning jack can be a pneumatic jack controlled by a solenoid valve with manual or automatic triggering. The pneumatic cylinder is calculated so that its power is high enough to cut all types of existing or future bands. The return stroke of the cylinder is preferably as small as possible. On the other hand, to be able to cut a wide and thick strip or a thin and very malleable strip, it is advantageous to be able to adjust the play existing between the blade and the counter blade as well as the sharpening angles so that the cut is sharp and precise.

The presence of a straightening roller prevents the strip from deflecting to the left or to the right when cutting. Indeed, said roller keeps the strip perfectly perpendicular to the cutting plane, which gives perfectly square cuts. As will be detailed below, the cutting device comprises, in addition to the aforementioned blade, a counter blade, said blade being arranged perpendicular to the plane of the strip between the unwinding assembly and the 4 means of application and cooperates, for cutting, with said counter blade extending on a support parallel to said blade between the upper drum of 1 unwinding assembly and the applicator roller, so as to produce an instant cut without stopping of the machine This “cutting on the fly” device makes it possible to obtain speeds of application of the strip much higher than those which are possible under the devices of the state of the art. As already mentioned, the blade and / or the counter blade is made of hardened steel, to ensure sufficient mechanical resistance of the cutting instruments as well as a high and constant cutting quality

The autonomous tape laying device furthermore comprises a control and display console for controlling the device. This console will be described in detail below and has, in addition to the usual members making it possible to operate the apparatus, a programmable automaton for managing the laying of the strip The device comprising a control and display console having a programmable automaton for managing the laying of the strip is characterized in that said console comprises a control member making it possible to choose between three ways of making the cut, either manually, or semi-automatically, or automatically The invention will be better understood, thanks to the description below, which relates to a preferred embodiment, given as of nonlimiting example, and explained with reference to the appended schematic drawings, in which FIG. 1 is a side elevation view in section of a conforming device me to the invention, Figure 2 is a partial view on a larger scale, in side elevation and in section, of the path and the different means acting on the strip, from the storage reel to the application of the strip on the ground, FIG. 3 is a front view on a larger scale of the different means of FIG. 2, acting on the strip of the storage reel until it is applied on the ground, and FIG. 4 is a partial view in plan, on a larger scale, of the rollers mounted on the upper roller axes of FIG. 2

In accordance with the invention and as shown more particularly in FIG. 1 of the accompanying drawings, the autonomous device 1 for laying strips 2, in particular for marking floors, essentially consists of a rolling chassis 3, an assembly (not shown ) driving the chassis and actuating different devices and means of unwinding the strip 5 2, by a pivot axis 4 on a support roller on the chassis 4 ′, a motor 5, preferably a thermal motor, a compressor 6 for supplying the pneumatic circuits, an air reserve 7, a hydrostatic bridge 8, a control and display console 9 provided with control members 10 and connected to a source of electrical energy such as a battery (not shown)

The traction part of the autonomous device 1 for laying strips 2 can be produced, according to the drive assembly, according to several modes (self-propelled, self-propelled), the mode described below, by way of nonlimiting example, being a self-propelled mode As shown in FIG. 2, the path traveled by the strip 2 goes from the reel 1 1 to its application on the ground at the level of the applicator roller 33. The reel 1 1 for storing the strip 2, mounted on a spool pin 12, is placed in a special housing on the chassis. The unwinding of the strip 2 can be adjusted in its position and in the tension of the strip which passes by means of clamping means 13 produced in the form of flanges 14 or the like located on the spool pin 12

The strip 2 is pulled up, adhesive part 2 'upwards, in the direction of unwinding indicated by the arrow in the direction of the straightening means 15 constituted by a straightening pin 16 provided with a straightening roller 17 located just before the assembly of unwinding 19. As shown in FIG. 3, this rectifier axis 16 is mounted perfectly parallel to the unwinding assembly 19 between flanks 41 and 41 'connected to each other by a cross-member 36', the rotation of the strip 2 around of the axis preventing deterioration of the latter by eliminating friction as much as possible when scrolling. The straightening roller 17 is preferably provided with several guide means 18 such as rings, flanges or the like which regulate and maintain the straightening, the width and the position of the strip 2. Of course, the adjustment of the this or these guide means 18 must be made in the same alignment as the flanges 14 of the clamping means 13 of the spool pin 12. The guide means 18 of the straightening roller 17 can be fixed by blocking means 18 'usual such as, for example, knurled bolts or screws or the like.

It is also possible to provide several reels 1 1 of strip 2 on the reel holder 12, for example, to produce a pavement marking produced in the form of two parallel lines. It is then advisable to add additional pairs of flanges 14 on the spool pin 12 as well as additional pairs of guides on the rectifier axis 16. 6 simultaneously two or more reels of tape and obtain a perfectly parallel marking

In addition, a symmetrical positioning of the coils 1 1 following 1 reel holder axis 12 will also allow symmetrical marking, for example, with respect to the median axis of the roadway

Leaving the storage reel 1 1, the strip 2 is guided and led by the rectifier axis 16, just before being introduced into the unwinding assembly 19 of the strip 2 which is in particular composed of a roller feed 20 made, for example, of natural rubber or polyurethane, of a series of upper roller-bearing axes 21, 22, 23 and of a fixed axis 24 (FIGS. 2 and 3) At this point, the strip is pinched between the first upper roller carrier axis 21 and the small supply roller 20 mounted in contact with the point rollers of this first axis. The combination of the straightening roller 17 with the continuous nipping between the upper roller holder axis 21 and the supply roller 20 guarantees that the strip 2 cannot move laterally, neither to the left nor to the right. These means associated with the spool pin 12, also fixed to the chassis, and the flanges 14, which are adjustable, in particular in width, and which tighten the sides of the storage spool 1 1, make it possible to hold the strip 2 always slightly taut on the rectifier shaft 16, the flanges 14 on the sides of the coil preventing the latter from continuing to rotate at the time of cutting under the effect of inertia

As shown in particular in FIGS. 2 and 4, the rollers of the upper roller-carrying axes 21, 22 and 23, entrainers and separators, are advantageously produced in the form of rollers with points or projecting parts 25, these points or projecting parts 25, made in the mass or attached may be sharp or slightly broken Figure 4 shows that the rollers of the upper roller carrier axes 21, 22, 23 are staggered from one roller to another and with intersection of their generatrices 21 ' , 22 ', 23' and they are integral in rotation with one another by means of the synchronization means produced here in the form of the pulleys 21 ", 22", the double pulley 23 "and the flexible upper belt 26 The axis 23 also drives, by means of the double pulley 23 ", the pulley 31" and the lower flexible belt 26 ′, the lower roller carrier axis 31 which in turn drives the roller carrier axis lower 32 through p oulies 32 ", 32 '" and lateral belts 35 and 35' It is thus possible to carry out a perfect drive of the strip 2. In order to avoid any risk of jamming of the strip 2, in particular when the latter is cut, and in particular for products such as aluminized strips, the lower roller axes 31, 32 being located just below 7 the blade 30, and which are, moreover, produced in a similar manner to the upper roller axes 21, 22, 23, are therefore also synchronized in rotation with the unwinding assembly 19 located above the blade 30 by synchronization means similar to those used for synchronization of the upper roller-carrying axes 21, 22, 23, namely, the pulleys 31 ", 32", 32 '", the flexible belts 26, 26', and lateral 35 , 35 'A belt 26' synchronizes in particular the axis (s) of the roller carrier (s) 21, 22, 23 with the axis (s) of the roller carrier (s) ιnféπeur (s) 31, 32, the rollers of one or more axis (s) of the roller carrier ιnféπeur (s) 31, 32 which can cause the front or front end of the new portion of strip to be cut which avoids jamming (FIG. 3)

The width of the arrangement of the strip 2 has been optimized so as to have a larger surface, and therefore a number of points or projections 25 of the rollers, thereby reducing the pressure exerted on the strip 2 This considerably increases the flexibility of the course, taking into account that all the axes which carry the rollers are synchronized in rotation, with the exception of the fixed axis 24 and the guide axes 42, 43, 44 not driven The rollers of the different axes support rollers are preferably mounted in staggered rows and are in turn drive-separators, when the strip passes over the rollers with spikes or projecting parts 25 Synchronization also makes it possible to reduce the pressure applied to the upper cylinder 36 The advancement comfort of this device autonomous installation 1 of bands 2 is increased by the presence of an additional hydrostatic bridge 8 connected to a motor 5 for its displacement, said motor 5 in. uvant also to drive a compressor 6 intended to supply pressurized air for the supply of different actuating members, for example, of the jack type 36, 40 Unlike a gearbox whose ratios are constant, the hydrostatic bridge 8 allows advancement of the autonomous device 1 for laying strips 2 with a flexible advance controlled at all times

When the strip 2 is put into place in the unwinding assembly 19, the end of the strip 2 is introduced between the points or projecting parts 25 of the rollers of the first upper roller-carrying axis 21 and the feed roller 20, these two elements being pressurized against each other The user of the machine then actuates the control member or members 10 of the control and display console 9 which corresponds to the supply of the upper cylinder 36 against the upper drive drum 27 The upper roller axes 21, 22, 23 being in contact with said upper drum 27, the user then only has to turn manually, by means of the wheel 37 , the upper drum 27, in the desired direction to advance or retract the strip 2 and thus position it. The strip 2 is then entrained by the rollers of 1 upper roller holder axis 21 and arriving at the upper roller holder axis according to 22, the latter repeats 1 operation until the strip 2 is at the level of the counter blade 28 of the cutting device 29 The strip 2 is thus placed below the carrying axis upper roller 23 where the fixed axis 24 is located, the rollers of which are mounted free and insane with one another, said fixed axis being mounted, integral with the cutting device 29, between the slide carriers 49 and 49 'of the blade 30 (fig 3) From the console 9, the operator triggers the laying of the strip 2 by an electric button starting the automation the applicator roller 33 which is in contact with the ground, and whose movement in lotation is synchronized with the movement of the machine, synchronizes the drum in rotation upper 27 by means of the belt 38 and pulleys 27 "and 33 ', the belt 38 being free and not tensioned at rest The tension roller assembly-veπn 39 comes to tighten, at the time of the setting in motion, the belt 38, and thus causes the synchronized rotation of the upper drum 27 and of the applicator roller 33 and by the same, the movement of the strip 2

The operator then activates, via the control members 10 of the display and control console 9, the programmable automaton for managing the laying of the strip 2, making it possible to choose between three ways of making the cut. , either manually, or semi-automatic, or automatic In manual mode, the operator causes the cut from the console 9, in semi-manual mode, the next pose is done only on the order of the operator, the cut being caused by an electronic management and in the automatic mode the electronic management repeats a cycle of measuring the length of the strip 2, the vacuum to be left between two pieces of strip 2 consecutive and the triggering of the cutting

As can be seen in FIGS. 2 and 3, the sectioning device 29 of the autonomous device 1 for laying strips 2 is constituted by a transverse blade 30 guided between the slide carriers 49 and 49 'and actuated at its end opposite to the cutting edge by a sectioning jack 40 mounted on a crosspiece 40 ', said blade 30 being arranged perpendicular to the plane of the strip 2 between the unwinding assembly 19 and the application means 34 and cooperates, for sectioning, with said counter blade 28 extending on a support 28 parallel to the blade 30 between the upper drum 27 of the unwinding assembly 19 and the applicator roller 33, so as to produce a cut 9 instant without stopping the machine Furthermore, this cutting must be carried out fairly quickly, so that 1 chewing effect does not come to silence the strip 2 between the blade 30 and the counter blade 28, which would have the consequence that the strip 2 would not be cut A satisfactory cutting speed during the travel of the strip 2 is obtained by the correct choice of the power of the sectioning jack 40, by optimizing its supply of compressed air from the compressor 6 and thanks to the air reserve 7 by means of electro-distributors controlled from the control and display console 9 As an indication, the pressure of the compressed air is between approximately 6 and 8 bars Of course, the sectioning jack 40 as well as the other jacks used in the present invention can also be actuated hydraulically or in an equivalent manner In order to guarantee a high and constant quality cut, the blade 30 and / or the counter blade 28 is / are preferably realized in hardened steel, the blade 30 being moved by the sectioning jack 40 It is also noted in FIGS. 2 and 3 that the supply roller 20, the axis fixed 24 and the upper roller-carrying axes 21, 22, 23 are mounted on a pivoting frame, comprised between two sides 47, 47 'connected by a cross-member 48

Said pivoting frame is articulated around the upper roller carrier axis 23 and positioned by an upper cylinder 36, the application of the rollers of said upper roller carrier axes 21, 22, 23 on the strip 2, against the upper drum 27 of traction and the counter blade 28, being adjustable via the console 9 for control and display The sides 47 and 47 ′ keep all of these members perfectly parallel to one another in a compact arrangement also called laying head which is delimited by the side walls 41 and 41 ′ and which connects to the rolling chassis 3 by pivots oscillating around the axis 23 In this way, the laying head can oscillate (pivot) around said axis 23, the latter passing through the assembly of right through and being housed in bearings mounted on the side walls 41, 41 'while being positioned by the upper cylinder 36 fixed on the crosspiece 36' itself fixed on said side walls 41, 41 'by conventional means iques known to those skilled in the art This arrangement has the advantage, when the strip 2 passes under the applicator roller 33, to allow the laying head to perform a slight upward oscillation, the rest of the machine remaining perfectly stable , which ensures perfect straightness for laying the strip 2 on the ground

As can be seen very clearly in FIGS. 2 and 3, the strip 2 passes, in its advancement, between the blade 30 and the counter blade 28 and under the lower roller-bearing axes 31 and 32 which are rotated by the 31 "pulley mounted on the lower roller carrier axis 31 and interconnected by the belts 10 lateral 35, 35 ', the axis 31 being driven in turn by the upper and lower flexible belts 26, 26' moved by the upper roller-bearing axes 21, 22, 23. The rollers (not all shown) of the two lower roller bearing axes 31 and 32 are also staggered therebetween, the aforementioned axes being mounted on sealed bearings as are preferably all the rotary axes of the present invention. The strip 2 continues its routing and arrives by means of application 34 of the strip 2 on the ground, essentially constituted by at least one lower roller-bearing axis 31, 32, at least one guide axis 42, 43, 44 and the applicator roller 33 which can be a second driving drum. The guide pin (s) 42, 43 and 44 are mounted fixed in front of the applicator roller 33, seen in the direction of travel, between the lateral support pieces 50 and 50 'and have rollers (not all shown) which rotate, free and crazy, between circlips (not shown). Passed under the axis 44, the strip 2 touches the ground and the autonomous laying device 1, moving forward, causes the applicator roller 33 to catch the end of the strip 2 which it passes under it. Thus, the strip 2, brought by the unwinding assembly 19 is perfectly guided and applied to the ground.

The application means 34 of the strip 2 is in drive connection with the unwinding assembly 19 by means of a belt 38 mounted between the pulleys 27 "and 33" provided respectively on the upper traction drum 27 and the shaft of the applicator roller 33, the tension roller-jack assembly 39 playing the role of a clutch by tensioning the belt 38 in service. The tension roller-jack assembly 39 may be constituted, as shown in FIG. 2 of the accompanying drawings, by a roller 45 mounted at the end of the piston rod 46 of a control jack or by one pulleys 27 "and 33" formed as a pulley with variable diameter under the action of a jack, a cam, or the like. Furthermore, it will be noted that all the jacks are controlled by solenoid valves controlled by the automation of the console 9 for control and display. In a particular embodiment, a device according to the invention is characterized in that the upper drum 27, the applicator roller 33 (lower drum), the upper roller axes 21, 22, 23 and lower 31, 32, entrainers and separators, are mounted on ball bearings and are, at least during the unwinding and installation, synchronized in rotation with one another by at least one synchronization means 21 ", 22", 23 ", 26, 26 ', 27 ", 31", 32 ", 32" ', 33 ", 35, 35', 38.

The device according to the invention operates as follows: after insertion of the start of the strip 2 in the unwinding assembly 19 and connection of the electrical circuits of the console 9 for control and display by unlocking a general switch (not shown), 1 operator initiates the work cycle by engaging the forward gear and by actuating the clutch produced by the 'roller tensioner-véπn 39 of the drive of the unwinding assembly 19 The roller-bearing axes upper (s) 21, 22, 23 and ιnféπeur (s) 31, 32 as well as the fixed axis 24 and the or the guide pin (s) 42, 43, 44 and the application means 34 then allow a guided progression from the strip 2 towards the blade 30 Before cutting the blade 30, the aforementioned clutch is disengaged to avoid advancing the strip 2 during the cutting time After returning to the rest position of the transverse blade, the aforementioned clutch is again brought into the engaged position with the unwinding assembly 19 of the strip 2 The latter is then driven by the lower roller axle (s) s 31, 32 and guided by the applicator roller 33 and the axis (s) 41, 42, 43 to the ground It is, of course, also possible to carry out a continuous laying of the strip 2 Finally, after setting off the electrical control means by action on a general safety switch, the operator can move with the device 1 without unrolling and placing the strip 2. Thanks to the invention, it is possible to produce an autonomous laying device 1 of strips allowing rapid and quality fitting of said strips 2, without effort or constraint up to the applicator roller 33, and without risk of deterioration of the strips during laying

Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the protection field of the invention.
