Abstract

Conveyor of bulk product according to Claim 1 of the main patent, characterised in that means are provided for modifying, as desired, the length of the active portion of the transporting band supporting the product, so as to position the unloading point, moving it towards or away from the supply point. <IMAGE>

Description

 This Addition Certificate concerns a variant of the bulk material loading gantry described in the main patent.

 In the system described in the main patent, the conveyor belt is of constant length and the carrier stations are joined to each other by flexible links of constant length, the carrier station located furthest forward being joined to its front at a positively driven carriage capable of exerting traction or pressure on all the supporting stations, so as to keep behind this carriage the necessary and sufficient active length of conveyor belt, the non-active length of conveyor belt being compensated by deflection rollers mounted respectively on this pouring carriage and on the end of the loading boom, the chute for taking the products to be discharged into the vessel being moved by the same means as those which control the pouring carriage.

 This arrangement is very clearly superior to the previous system of telescopic boom which must gradually come to be housed in the structure of the handling installation, but it still has, despite this improvement, the drawback of requiring arrangements for storing small trolleys in the maximum retraction phase of the strip, which still leaves a certain distance from the feed point to the loading point.

The purpose of this addition certificate is to further reduce this distance from the feed point to the unloading point and to simplify the structure of said installation in the feed area.
To this end, according to the variant which is the subject of this
Certificate of addition, the conveyor belt is always of constant length throughout its development, but it is carried in its active part, by a series of horizontal and oblique roller supports mounted on tilting gantries installed at regular intervals and at fixed position in the structure of the conveyor to allow the free movement of the roller-carrying carriage for returning the conveyor belt.

The tilting from the horizontal to vertical position of each gantry roll holder is made automatic as and when
measurement of the deployment of the active part of the strip
conveyor on the one hand thanks to oblique ramps integral
of the return roller carriage on the one hand, and on the other hand,
thanks to rollers secured to tilting gantries. In the
retraction phase, the erasing of said gantries is carried out
by collision of these with said carriage to arrive in
horizontal position simply by gravity.

The product conveyed by the conveyor belt falls into
a hopper fixed to the return carriage and located to the right of the
first deflection roller of said strip, so that
all running on a raceway required the
particular design of said hopper by dividing it in two
bilateral conduits which surround the parts of the strip
non-active conveyor and the lower part of the structure
of the conveyor. The two bilateral conduits are joined at their base in a common chute.

The invention will be better understood by the description below
after the embodiment and illustrated by the accompanying drawings
whose
FIG. 1 represents the entire conveyor,
- Figure 2 shows a perspective view of the
conveyor belt unloading system without its hopper,
- Figure 3 shows a perspective view of the
evacuation hopper.

Referring first to Figure 1, there is shown a conveyor as a whole according to the invention
consisting of a main structure (1) supporting the entire
system and a secondary reinforcement structure (2) connected to the first in its lower part. They are produced by bars of metal profiles, but any other method of metal construction can be envisaged.

The very hollow interior of the main structure (1) made it possible to install a carriage (4) and its raceway
(4 ') over its entire length. Motorization means by winches (6) and (6 ') make it possible to make return journeys of said carriage (4).

 A conveyor belt (3) of flexible material of known manufacture has a constant length in its development and passes successively in a series of scroll rollers 5A - 5B - 5C - 5D but of which at least two (5) and (5 ') are coupled to the carriage (4).

 If, by known means, bulk product P is deposited on the conveyor belt, it will be conveyed to the roller 5 then from there will fall by gravity. To avoid its dispersion, it will be recovered in a hopper (7) fixed to said carriage (4).

 By translating the trolley (4) roller (5) hopper (7) assembly, it is possible at any point along the length of the conveyor to place the product P 'to be discharged at the desired location.

 To stabilize the product in the central part of the conveyor belt (3) and relieve it of its load, carrier rollers (10) associated with guide rollers (11). mounted obliquely, arranged at regular intervals, transform said conveyor belt into a movable gutter.

 It will be easily understood that any movement of the carriage (4) and of its assembly modifies the active length of the conveyor belt (3) and therefore that the movable gutter must adapt and conform as the displacement occurs, which implies to take certain measures for the pairs of supporting rollers (10) and oblique guide rollers (11) which can no longer remain at a fixed door.

 The known solution described above and which consists of conveying the pairs of rollers (10) and (11) using small carriages still leaves an unusable travel of the active belt of the conveyor in particular by approaching the feed zone and gradually concentrating a non-negligible mass due to the rolling means.

 On the other hand, by providing eclipsable or retractable means which are the subject of the present invention, the possibilities of the conveyor are improved.

 Such means are described below with reference to Figure 2 where we see some elements of the main structure (1) and secondary (2), the carriage (4) with its deflection rollers (5) and ( 5 ') of the conveyor belt (3), the hopper (7) is deliberately not shown. It is in an intermediate position where a gantry 9a is clearly distinguished in a horizontal position, while the gantry 9b is in a vertical position and comes to support the conveyor belt (3) by the roller (10) while the flatness of said band is modified in the form of a gutter by the compulsory guide rollers (11).

Each gantry can tilt by oscillating around two articulation axes (13) connected to the side members of the structure (2).

 The lifting kinematics of the gantry 9a for example is produced by the inclined ramps (14) integral with the carriage (4) and by the two lateral rollers (12) integral with the gantry 9v when the carriage (4) moves along the arrow (F ) the bottom of the ramp (14) approaches the roller (12) then, when these two parts come into contact, if the progress of the carriage (4) continues, the roller (12) will follow a trajectory defined by the displacement of the ramp (14) generating the elevation of said roller and consequently the progressive lifting of the gantry 9a When the roller (12) has reached the top of the ramp (14) said gantry will be substantially vertical. adequate purity of the system the roller (12) will escape from the ramp (14) only after pressing said gantry on its stop (15) and in this position it will have slightly exceeded the verticality V by a small angle, this particularity has the effect of maintaining perfectly in support said gantry and avoiding its re conversely by certain reactions of the conveyor belt (3) during travel.

 When the carriage (4) reverses its direction of travel, it will collide with the gantry erected on its path which, after having exceeded verticality V, will fall by gravity onto rest stops (16).

 FIG. 3 shows the particular arrangement of the hopper T recovering the product P conveyed by the conveyor belt (3) returned in the opposite direction by the roller (5). A first receptacle in the form of a box (17) receives the product P fallen by gravity and the bottom of which is divided into two conduits (18a) - (18b) deviating on either side of the axis of the conveyor which allows the conveyor belt (3) to pass in its return path and the lower part (2) of the structure of said conveyor. The two conduits (18a) - (18b) meet at their respective base in a common chute (19) concentrating the product P to be discharged. The shape of this hopper is not limiting since it depends on the architecture given to the structure of the conveyor.
