Abstract

The present invention relates to a movable handling apparatus comprising a movable frame (1) on wheels (2) which carries a vacuum pump (7) actuated by a motor (6), to which pump filters (10) and (12) are branch connected and which are connected to a reserve vessel (13), and a flexible pipe (16), wound up on a winding device (34), is branch connected via one end to said reserve vessel, which pipe (16) is joined via the other end to a rigid suction nozzle carrying a gripping suction pad.

Description

 The present invention relates to a mobile device for handling materials used dry and laid by juxtaposition or interlocking such as tiles, comprising a lance for remotely gripping the material, which lance is associated with a suction means.

 Currently, for example, to cover a roof with tiles, artisans store the tiles in several places, then manually position said tiles on the battens, which requires a multitude of movements and at least four body flexions per tile, making the tedious task.

 The working method is similar for the installation of interlocking pavers; in addition, the craftsman works on the knees.

 The invention, object of the present, overcomes these drawbacks in that it reduces the arduousness of the work; in fact, the device s1 uses in the standing position and allows, in a few movements, the capture of the material at the storage point and the nesting with the other materials already in place.

 The invention, object of the present, comprises a movable frame which carries a vacuum pump actuated by a motor1 to which pump is connected one or more filters, and the last filter is connected to a reserve tank on which tank is connected a lance suction through a flexible conduit, which lance is provided at its end with a suitable suction cup.

 The vacuum pump is operated with an electric motor or an internal combustion engine.

 The suction lance, as required, is simple or telescopic and has one or more elbows along its length to be better adapted to the handling of different materials.

 The invention is set out below in more detail, with the aid of drawings showing only one embodiment by way of nonlimiting example.

 Figure 2 shows a side view, in elevation, of the mobile handling device.

 Figure 4 shows, partially, a telescopic suction lance.

Figure 6 shows another type of suction cup.

 Figure 7 shows a vertical section of a heavy particle filter.

 FIG. 8 represents a vertical section of a vacuum reserve tank.

 Figures 1,2,3,4,5,6, and 7 show a mobile material handling device used dry to be deposited or placed by juxtaposition or nesting, comprising a horizontal chassis 1 substantially rectangular mounted on two wheels 2 to the front, which frame I made of steel tube has its two lateral sides surmounted respectively by an inverted tube 3 forming an inverted V, one end of the tube 3 is fixed near the front wheel 2 and the other extends under the rear chassis 1 forming a stand 4 for the stability of the device in the operating position.

The rear end of the horizontal chassis includes hooks 5 for receiving and adjusting handling arms.

At the front of the chassis 1, are placed the electric motor 6 and the vacuum pump 7, which vacuum pump 7 is connected by a conduit 9 to a first oil bath filter 10, and the latter is connected with a conduit 11 to a second large particle filter 12, which filter 12 communicates with a reserve tank 13 by means of a conduit 14, which reserve tank 13 has a suction port 8 provided with a quick connector 15 for fixing one end of a flexible conduit 16 which connects said tank 13 to a suction lance which can be simple or telescopic. The simple lance comprises a bent tube 17 which carries, near the end connected to the flexible conduit 16, a vacuum control and at the other end a suction cup 18.

In both cases, the suction lance has a vacuum control which comprises a longitudinal lever 19 which pivots by one of its two ends on a rod 20 fixed on the body of the control itself, and at its other end, said lever 19 carries a spherical body 21 with which it obstructs, under the pressure of a hand for example, a depression orifice 22 positioned opposite on the extension of the body of the control, causing by suction the seizure of the material with a or more suction cups.

For the laying of the material, the pressure is released on said lever 19 and the latter rises automatically under the impulse of a piston 23 with spring thus freeing the orifice 22 and creating a vacuum at the level of the control.

The vacuum control contains a valve (not shown) actuated by the handle 19, by any known means, closing the suction circuit before the opening of the depression and opening it after the latter has stopped, to limit the air intake volume during each material entry.

 The suction cup 18 fixed on the end of the lance has a frustoconical shape, made of a flexible material such as rubber, and has circular bulges 24 over the entire height allowing a slight crushing of the suction cup when gripping the material.

 This suction cup fits on the end of said lance, by its narrowest side and is immobilized if necessary by means of a tightening ring 25.

 Naturally, the suction cup 18 is interchangeable and for a different use, the end of the lance receives a head with several branches 26 which are respectively provided with a suction cup 27.

These suction cups can vary in shape for better adaptation to the material.

Inside each suction cup, whatever its shape, is positioned a flat grid 30 performing the function of a filter to retain large particles such as fragments of materials or pieces of plants during suctioning.

 According to a preferred embodiment, the lance is telescopic and comprises a first tube 28 which carries at one end the vacuum control and, its other end slides partially in a second tube 29 of slightly larger section, between which tubes 28 and 29 are placed O-rings to absorb any vibrations.

 To effectively grip and hold the material at the end of the suction cup by suction, the telescopic lance comprises a conduit 38 housed in the tube 28 and fixed at one end to the vacuum control, which conduit 38 exits the tube 28 at the height of the elbow and is connected to a flexible helical sheath 39 which evolves around the tubes 28 and 29, which helical sheath 39 is extended by a conduit 40 to the suction cup. The conduit 40 enters the tube 29, through an opening arranged for this purpose, and is fixed jointly with the latter on the narrow end of the suction cup with any suitable means.

A handle 44 fixed to the tube 29 allows the lance to be maneuvered as desired in terms of length and to pivot the tube 29 to present the suction cup at the desired angle.

 In the case of a simple lance (fig. 5), not telescopic, the tube 17 carries the suction cup 18 at the end and encloses a conduit 38 of a single length which connects the vacuum control to said suction cup 18.

 The tank 13 constituting a vacuum reserve is equipped with an adjustment means 31, for assessing the minimum and maximum vacuum, making it possible to automatically start or stop the motor of the vacuum pump to handle materials in the event of use. temporary.

 The autonomy of the tank 13 allows a reduction in the efforts of the motor and the pump. The reserve tank has at one end a manhole closed with a plate 32 by means of screws allowing internal cleaning.

 The upper end of the two tubes 3 of the chassis carries a horizontal rod 33 on which a reel 34 freely carrying the flexible conduit 16 connecting the reserve tank to the suction lance.

 The filter 12 for large particles comprises a preferably cylindrical tank with an inlet 41 and an outlet 42 of the circuit located at the top of said tank, which inlet 41 of the suction circuit has the conduit 14 which extends to the bottom of the tank and, at the ends of said tank are provided openings for emptying, which are closed during operation of the device with threaded plugs 43.

 According to a preferred embodiment, (FIG. 8), the reserve tank 13 comprises an internal partition 35 arranged in staggered rows and vertically so as to retain the large particles, and the suction openings 36 and 37 are located at the two ends in such a way. that the suction circuit bypasses the entire partition.

This tank thus equipped plays the role of reserve tank and large particle filter, making it possible to remove the filter 12.

 An electric cable 45 connects the sector to an on-off contactor box 46 which controls the electric motor of the vacuum pump, causing suction through all the elements to the suction cup.

 The invention, object of the present, is more particularly conceived for the manipulation of building materials such as mechanical tiles, light elements which can constitute a suspended ceiling, interlocking pavers, etc ... but can be used for any other material suitable for handling with this device.
