Abstract

The removable brush (26) is arranged under the conveyor belt and presses against the belt surface (10) as the belt (18) runs along the lower side of the conveyor. The brush is held at its ends (32,34) in two support arms (36,38) these arms (36,38) swing around an axis (40). At the other ends of the arms (36,38) a counterweight (50) is fitted. The arms can be considered to have two section a front section pair (42,44) and a rear section pair (46,48). A front section arm (42) is hinged which enable it to be set in two positions the first position parallel to the other front arm (44) so as to hold the brush and a second swung out position to enable the brush to be released. The brush is mounted on apolygonal section hollow shaft (28) which is driven by a motor (30).

Description

ARRANGEMENT OF A REMOVABLE ROTARY BRUSH
CLEANING, PARTICULARLY FOR CONVEYOR BELTS
The present invention relates to an arrangement of a removable rotary brush, in particular of the type used for cleaning conveyor belts.

 It is known that conveyor belts which transport bulk materials such as, for example, tobacco leaves, have their surface loaded with deposits which must be removed as and when required to ensure proper operation. These belts, based on reinforced rubber material, are generally stretched between two drums, one of which is a motor, with support rollers in sufficient number to take up the weight of the load of the belt.

 The two drums and rollers are supported by a frame fixed to the ground.

 The conveyors having limited possibilities of inclination as a function of the material transported and no possibility of orientation in the horizontal plane since such conveyors cannot be curved, resumptions are carried out by several successive conveyors judiciously oriented so as to connect the two starting and ending points, chosen or imposed.

 Each conveyor thus comprises a single mat which decomposes into a part stretched over the top and carrying the load and a return part under the bottom, from the drum motor.

 The well-known solution for cleaning such conveyor belts consists in placing immediately downstream of the motor drum, on the return part of this belt, a rotary brush, motorized to rotate it counter-rotating, arranged in contact with the belt.

This brush, the support shaft of which is transverse to the direction of movement of the conveyor, is generally mounted at
The end of the arms provided with counterweights and articulated in their middle about an axis, thus achieving a tilting assembly. The set of arms, brush and counterweight is adapted and adjusted to ensure a constant and continuous given pressure of the brush on the carpet.

 Such carriers are regularly maintained and satisfactory cleaning of the carpet and the brush and above all its change requires being able to access this brush and to be able to easily remove it from the assembly.

It turns out that this brush is generally accessible to the right of the motor drum because the free space below the conveyor is most of the time reduced and the space at the front of the conveyor, at the point of unloading,
I am even more since there is in this place either a hopper, or another receiving conveyor, or several conveyors. Maintenance personnel are often unable to access the brush except to climb on the belts of other conveyors for example, which is not the right solution.

 It is also known that conveyors are used in large capacity industrial installations, generally operating continuously and maintenance must be carried out in a limited time.

 Also, the present invention provides a particular arrangement of a removable brush for cleaning the conveyor belt which allows very easy disassembly, with lateral access, this arrangement remaining simple and reliable in relation to the needs of the machine on which it is willing.

 To this end, the arrangement according to the invention of a removable rotary brush disposed in abutment on the relaxed part of a conveyor belt, said brush being rotatably mounted between the first ends of two support arms, these arms being tiltable around an axis, the second ends carrying a counterweight, thus determining two upstream half-arms and two downstream half-arms, left and right, by placing themselves upstream of the relaxed part of the belt with respect to the direction of travel of the belt, is characterized in that one of the upstream half-arms comprises articulation means to allow it to take a first position in which this half-arm is substantially parallel to the other and a second position in which this half-arm is open to allow lateral access to the roller.

 According to another characteristic, the brush is mounted coaxial with a drive shaft and comprises means for connecting in rotation with this shaft.

 More particularly, the shaft is of polygonal section and the brush is mounted on a hollow shaft of conjugate section.

 In this embodiment, the drive shaft is mounted fixed in translation and free in rotation relative to the monolithic upstream half-arm.

 Preferably, the drive shaft is driven by a gear motor fixed on the upstream monolithic half-arm.

 According to an improvement, the upstream articulated half-arm comprises locking means in the first position.

The invention is described below according to a particular, non-limiting embodiment, this with regard to the appended drawing in which the figures represent:
- Figure 1, a perspective view of a conveyor belt equipped
a brush,
- Figure 2, a side elevational view of the elements of Figure 1, and
- Figure 3, a sectional view through a horizontal plane along line 3-3
in Figure 2.

 In Figure 1, there is shown a conveyor belt 10 with a motor drum 12 which drives a tensioned part 14 which supports the load 16 and which releases below a relaxed part 18. The arrow 20 determines the direction of rotation of the belt.

 The chassis which supports this assembly is globally referenced by a unique reference 22.

 On the relaxed part, there is disposed a brushing assembly 24 of the carpet.

 This assembly comprises a brush 26, mounted coaxially on a drive shaft 28, advantageously of square section to ensure the rotational drive of the brush whose inner cylinder will have the conjugate profile. This drive shaft 28 is driven by a geared motor 30 and rotates in two bearings 32 and 34 carried by two arms 36 and 38 respectively.

 These two arms thus carry the drive shaft 28, the brush 26, and the gear motor 30.

 These two arms are mounted tilting relative to the chassis 22, about an axis 40 oriented transversely with respect to the direction of movement of the mat, that is to say parallel to the shaft 28 for driving the brush 26. Two left and right upstream half-arms 42 and 44 are thus determined, and two right and left downstream half-arms 46, 48 if one is placed upstream of the brushing assembly 24.

 At the end of the arms, opposite to that which carries the brush, there is provided a single bar for connection with a counterweight 50, adapted to ensure a substantially constant pressure of the brush on the carpet.

 According to the invention, the left upstream half-arm 42 which carries the bearing 34 is articulated relative to the arm 38, in the plane comprising the drive shaft and the brush as well as the two upstream half-arms.

 This articulation, as can be seen in FIG. 3, allows the opening of the half-arm 42 relative to the arm 38.

 The gear motor 30 and the drive shaft 28 supporting the brush 26 are held in cantilever by the right upstream half-arm 44.

The lateral access then allows maintenance personnel to remove the brush from the drive shaft on which it is mounted coaxially, by a simple translation.

 Such an arrangement is particularly practical because it allows the removal and handling of the brush at the place where there is the most space.

 Reassembly, provided that the replacement brush has been prepared in the immediate vicinity, is also quick since it suffices to thread the new brush onto the drive shaft 28 which has remained in place.

 Of course, it is necessary to provide locking means on the end of the drive shaft of the articulated left upstream half-arm 42, such as a screw key 52.

 Similarly, for safety, one can advantageously provide on one of the arms, in this case the arm 48, a key 54 cooperating with the chassis to prevent any untimely tilting of the assembly when the brush is removed.
