TECHNICAL FIELD
The invention concerns a device for conveying carbonaceous paste obtained from a mixture of liquid pitch and crushed coke intended to be fed to machines for forming molded blocks to be used to create electrodes, particularly anodes, for aluminium electrolysis.
BACKGROUND ART 2013231114 01 May 2017
Any discussion of background art, any reference to a document and any reference to information that is known, which is contained in this specification, is provided only for the purpose of facilitating an understanding of the background art to the present invention, and is not an acknowledgement or admission that any of that material forms part of the common general knowledge in Australia or any other country as at the priority date of the application in relation to which this specification has been filed.
Aluminium electrolysis using the Hall-Heroult process requires the prior production of carbonaceous anodes. The anodes are produced from liquid pitch and crushed coke, mixed and kneaded to obtain a relatively homogeneous paste. The obtained paste must then be molded into blocks in machines which compact them by vibration-compaction. The molded blocks are then introduced into ring furnaces, where they are baked to obtain the electrolysis anodes.
Vibration-compaction machines are known, also called vibration forming machines, vibro-compaction machines, or vibratory compactors. These essentially include a mold that is generally parallelepipedic in shape with a rectangular transverse cross-section, removably mounted onto a vibrating table constituting the bottom of the mold, and a pressing weight able to be introduced axially into said mold by the upper end of the mold. The vibrating table is secured to a frame by suspension means and is vibrated in a substantially vertical direction, along the axis of the mold, due to the effect of vibration actuation means.
This is the case in patent US 3,767,351, which describes a machine for producing blocks, and more particularly anode blocks, from granulates. The device consists of a vibratory or shaking table resiliently mounted on springs and to which a mold is attached. Under the vibratory table there are at least two rotating unbalanced weights which are mounted and rotated such that the horizontal components of the oscillations they generate in the table cancel each other out. The rotation of the unbalanced weights causes a substantially harmonic and vertical oscillation of the vibratory table, the vibrations thus compressing the granulates introduced into the mold and forming them into a compact block.
Such a known machine 1’ is represented in figures 1 and 2 of the present application. In that regard: 2013231114 01 May 2017
Figure 1 is a perspective view of an example of a vibration-compaction forming machine, in which the cover and the pressing weight are raised above the mold which is secured to the vibrating table; and
Figure 2 is a front cross-sectional view of the vibration-compaction forming machine represented in figure 1.
The machine 1’ essentially consists of a mold 1 that is generally parallelepipedic and has a rectangular transverse cross-section with a substantially vertical axis, vertically movable and removably mounted onto a vibrating table 2, and a pressing weight 3. After a paste 4 composed of liquid pitch and crushed coke is introduced into the mold 1, the paste mixture is compacted by the pounding of the pressing weight 3. For this purpose, unbalanced shafts 5 rotate in opposing directions and excite the table 2 which then assumes a vertical sinusoidal motion. Usually, the table 2 is installed on an elastic suspension 6 which limits the transmission of vibrations to the ground 7 and/or to the vicinity of the machine 1’.
The lower end of the pressing weight 3, known as the contact area 8, enters the mold 1 to give the shape of its lower surface to the molded block. Due to the effect of the vertical displacements the table 2 imposes on the paste 4, the pressing weight 3 bounces against the top of the block during shaping.
Said mold 1 is conventionally mounted onto guides 9a that slide vertically in sleeves 2a secured to the table 2, and is actuated by hydraulic cylinders 10 connected by the free end of their rod to the mold 1 and by the lower end of their cylinder to the table 2, said hydraulic cylinders 10 serving to limit the movement of the mold 1 on the table 2, and being used in unmolding to lift the mold 1 above the table 2 to allow lateral removal of a molded block from above the table 2.
The compaction machine 1’ also comprises a system for creating a vacuum in the mold 1, explaining the presence of a cover 13 which cooperates in a fluid-tight manner with the upper surface 14 of the mold 1 by means of removable mechanisms 15 which seal the cover 13 on the mold 1, the cover 13 being vertically movable relative to the mold 1, along with the pressing weight 3, by external means 11 such as a hoist or a hydraulic cylinder attached to a frame 2013231114 01 May 2017 structure (not represented) while being guided by vertical guides 9b for the cover 13 in sleeves 1b integrally attached to the mold 1.
To supply carbonaceous paste to the compaction machine described above, a set of additional equipment is required. A known feed device 100 is represented in figure 3. In that regard:
Figure 3 is a perspective view of a prior art assembly for producing molded blocks, representing the carbonaceous paste supply system and comprising two forming machines.
The feed device 100 essentially consists of a storage hopper 101, fixed relative to two compaction machines 1’a and 1’b positioned side by side. This hopper is used to collect carbonaceous paste produced in an upstream process, said storage hopper 101 acting as a buffer between the generally continuous flow of paste upstream and the discontinuous flow of paste needed to feed the two compaction machines 1 ’a and 1 ’b. A vibrating feeder 103 located under the storage hopper 101 draws out the carbonaceous paste in order to convey it and discharge it into a weighing hopper 104, said weighing hopper 104 being suspended on spring balances which allow determining the exact weight of the paste it contains. A motorized distribution flap 105, driven in a back-and-forth motion, guides the flow of paste between the discharge outlet of the vibrating feeder 103 and the inlet of the weighing hopper 104, thus evenly distributing the paste over the entire length of the weighing hopper 104. When the predefined mass of paste corresponding to the molded block to be produced is reached in the weighing hopper 104, the vibrating feeder 103 is immediately stopped in order to ensure weighing accuracy. The weighing hopper 104 is equipped at its base with an opening/closing system, comprising two half-shells 108 which move in a synchronized manner, said half-shells 108 being actuated by a hydraulic cylinder 109.
When the half-shells 108 of the weighing hopper 104 open, this causes the carbonaceous paste to fall into a conveying hopper 201 of a conveyance device 200. Once the weighing hopper 104 is emptied, the synchronized half-shells 108 are closed by the hydraulic cylinder 109 and the weighing hopper 104 is ready for a new weighing cycle. Once the conveying hopper 201 is loaded, the conveyance 2013231114 01 May 2017 device 200 is moved along two supporting and guiding rails 16, towards a first compaction machine 1’a for example, and when the conveying hopper 201 has reached the appropriate position, the carbonaceous paste contained in the conveying hopper 201 is released into the mold 1 of the machine 1’a by means of an opening/closing device similar to the one for the weighing hopper 104.
After the paste has been discharged, the conveyance device 200 is again moved in order to return the conveying hopper 201 to its position under the weighing hopper 104 where it is ready for a new load to be fed to a second compaction machine 1 ’b.
This system therefore allows two compaction machines 1’a and 1’b to operate simultaneously from a single supply point of carbonaceous paste, which doubles the production a single compaction assembly would achieve: while the first machine 1’a is being loaded with paste by the conveyance device 200 which travels from the feed device 100, the second machine 1’b can be in operation, with its cover 13 sealing the mold 1.
Note that in order to pour carbonaceous paste efficiently into a mold 1, as this paste is sticky in nature, the conveying hopper 201 is advantageously positioned exactly above the mold. This means that the assembly consisting of the cover 13 and the pressing weight as shown in figure 1 of each machine 1’a and 1’b must be separated from the mold 1 and sufficiently raised to allow the conveying hopper 201 to pass between them.
However, the installation described above can only comprise one or at most two compaction machines 1’. The conveying hopper 201 cannot, for example, serve a third compaction machine 1’ in alignment with the first two.
It is also advantageous for the compaction devices 1’ to be aligned along the same axis to facilitate removal of the molded blocks that are produced.
It is therefore not possible in such a configuration to raise the production capacity by increasing the number of compaction machines V to more than two.
In effect, when one machine 1’ is in operation, with the cover 13 sealing the mold 1, the conveying hopper 201 cannot pass above it, as the cover 13 and the 2013231114 01 May 2017 pressing weight 3 block its path. As a result, the conveying hopper 201 can only move between two machines 1’a, 1’b. One or more other machines 1’ in alignment with the first two would require the conveying hopper 201 to pass beyond the machines already loaded with paste, which is impossible if these machines are in operation.
This therefore limits the rate at which blocks are produced.
Consequently, a new carbonaceous paste conveyance device for an assembly for producing blocks by means of compaction machines in which the block production rate is increased is desirable. SUMMARY OF THE INVENTION.
In accordance with a first aspect of the present invention there is provided a paste conveyance device, able to move along a main roller track extending in a first direction, referred to as the main direction, in order to feed machines for forming molded blocks for use in creating electrodes for aluminium electrolysis, the paste conveyance device comprising: at least one main frame, comprising main rolling means, intended to cooperate with the main roller track in order to move the main frame in the main direction, at least one conveying hopper, supported by the main frame and suitable for being fed carbonaceous paste, and at least one opening/closing device of the conveying hopper, by which the paste is delivered to the forming machines, wherein the openings of said machines are offset to one side of the rails of the main roller track in a second direction, referred to as the secondary direction, perpendicular to the main direction, the main frame comprising guides defining a secondary roller track, extending in the secondary direction, and wherein the paste conveyance device additionally comprises a secondary frame, translationally connected to the conveying hopper in the main direction and secondary direction, and equipped with secondary rolling means cooperating with the guides of the main frame in order to move the secondary frame on the secondary roller track in the secondary direction between: 2013231114 01 May 2017 a retracted position, where the secondary frame is withdrawn within the main frame so that it is positioned between the rails of the main roller track, and a deployed position, where the conveying hopper and the opening/closing device are brought in line with the opening of one of the machines.
The movement of the conveying hopper in the two perpendicular directions thus allows bringing the carbonaceous paste from a single supply station to multiple compaction machines, in practice at least three, while allowing the machines to be running while the conveying hopper is in motion.
Advantageously, and in particular in the field of anode production for aluminium electrolysis, it is preferable that the opening/closing device of the conveying hopper is integrally attached to said hopper. The paste is thus delivered to the mold of a forming machine when the conveying hopper is placed above the mold, which is particularly advantageous in the case where the paste is intended for the production of anodes for aluminium electrolysis.
Preferably, the rolling means of the main frame and of the secondary frame are rollers, which are an efficient and low-cost means for allowing movement of the main frame on the main roller track and movement of the secondary frame on the secondary roller track.
In one embodiment, during the movement of the conveying hopper in the secondary direction, it alternately moves along the guides secured to the main frame, then along the edges of the upper face of the mold or along crosspieces arranged on each side of the mold. The positioning of the guides for the conveying hopper that are integrally attached to the main frame is designed to allow exact positioning in line with the edges of the upper face of the mold or with the crosspieces arranged on each side of the mold.
Preferably, actuating means, which are for example hydraulic or pneumatic cylinders, are placed between the secondary frame and the main frame in order to move the secondary frame relative to the main frame in the secondary direction.
In one particular arrangement, the supports (secondary rolling means) of the secondary frame comprise three pairs of rollers, with one pair of rollers placed on what can be called the rear side of the secondary frame, and two pairs of rollers 2013231114 01 May 2017 spaced apart from each other by a defined distance and placed on what can be called the front side of the secondary frame. This arrangement ensures the continuity of the support system of the secondary frame if, for practical reasons, it is necessary to leave a space with no support between the guides integrally attached to the main frame and the mold. For example, this arrangement allows the use of an additional cart, such as a maintenance cart, traveling above the molds in the main direction.
Advantageously, it is preferable that the conveyance device comprises means for measuring the amount of carbonaceous paste contained in the conveying hopper.
The electrodes, in particular, may be anodes.
In accordance with a second aspect of the present invention there is provided an assembly for producing molded blocks for use in creating electrodes for aluminium electrolysis, comprising: at least one conveyance device as herein before described, at least one device for feeding carbonaceous paste, which is supplied with carbonaceous paste from an upstream paste production process, at least one main roller track extending in the main direction, at least one forming machine, offset in the secondary direction relative to the main roller track, perpendicular to the main direction, said forming machine comprising at least one mold equipped with an opening in its upper part, the conveyance device being moved from the feed device to the forming machine by the movement of the main frame on the main roller track in the main direction, then the conveying hopper being brought by the movement of the secondary frame in the secondary direction on the guides of the main frame on the secondary roller track until said conveying hopper is facing the upper opening of the mold of the machine.
In one particularly advantageous embodiment, the assembly for producing molded blocks herein before described comprises at least three forming machines, each machine comprising at least one mold equipped with an upper opening, the upper openings of the molds of each forming machine being aligned with each other in the main direction, and being offset in the secondary direction relative to the roller track. The conveyance device can then bring the paste from a single feed 2013231114 01 May 2017 device to any of the three machines while the two others are in operation, without interfering with the cover displacement system of the machines in operation.
The electrodes, in particular, may be anodes.
The paste conveyance device described in the embodiment of the present invention is able to serve more than two vibration-compaction machines with a single conveyance means and from a single supply point. For this purpose, the carbonaceous paste conveyance device described in the embodiment comprises a conveying hopper whose main frame rolls on a roller track extending in a main direction parallel to the axis of alignment of the compaction machines and sufficiently distanced to allow said conveying hopper to move freely in the main direction without interfering with the components of the vibration-compaction machines. The conveyance device can thus be positioned opposite any compaction machine regardless of the operating state of the other machines. The conveying hopper, intended to hold the carbonaceous paste, is secured to a secondary frame, said secondary frame being mounted for example on rollers and installed on track rails secured to the main frame, said track rails being arranged in a second direction perpendicular to the main direction, i.e. perpendicular to the axis of movement of the main frame.
The conveying hopper benefits from a secondary movement, perpendicular to the main movement parallel to the axis of alignment of the vibration-compaction machines. This secondary movement allows the conveying hopper containing the paste to be brought above the opening of the mold of the vibration-compaction machines. The lower part of the hopper containing the paste is equipped with an opening/closing system consisting, for example, of two hinged symmetrical halfshells, which rotate in a synchronized manner due to gears integrally attached to their axis of rotation, said half-shells being actuated by a hydraulic cylinder which closes the conveying hopper during the loading and conveyance phases and opens it to discharge carbonaceous paste into the mold.

DETAILED DESCRIPTION OF THE INVENTION
Below is a description of a non-limiting example of an assembly for producing molded blocks, particularly for anode production, using carbonaceous paste.
In the following description, the terms "lower" and "upper" and the expressions "above" and "below" are understood to be in reference to the natural orientation of the production assembly and of the forming machines, as illustrated in the figures.
The assembly comprises a carbonaceous paste feed device 100, as described in the introduction, supplied as carbonaceous paste from an upstream paste production process.
The assembly additionally comprises forming machines that form the blocks by compaction. The assembly advantageously comprises at least three forming machines 1 ’a, 1’b and 1’c, as previously herein before described, as will be seen below. 2013231114 01 May 2017
As herein before described with reference to figures 1 and 2, each machine 1’a, 1b and 1’c, for forming anodes by vibration-compaction according to the invention as further described herein, comprises, in the conventional manner, a mold 1 that is generally parallelepipedic with a rectangular transverse cross-section, open at its two opposite horizontal faces which form its base and its upper surface 14, and removably attached to a vibrating table 2, constituting the bottom of the mold 1, and a pressing weight 3 intended to enter the mold 1 by the upper surface 14 of the mold 1 and supported under a cover 13 which is removably attached to the upper surface 14 of the mold 1 to ensure a fluidtight closure. In addition, the table 2 is installed on an elastic suspension 6 intended to limit the transmission of vibrations to the ground.
As seen above, the forming machine 1’a, 1 ’b, 1’c comprises means 15 for locking the cover 13 onto the mold, said cover 13 being suitable for covering the top of the mold 1 in a fluidtight seal.
In addition, the machine 1’a, 1’b, 1’c comprises a system for vertically displacing the cover 13 and the pressing weight 3 by means of a suspension rod 11. This displacement system is generally combined with a system (not represented in detail) for creating a vacuum in the mold 1 once sealed by the cover 13. Said system extends above the mold 1.
As was already described above in reference to figure 3, the machines 1’a, 1’b, 1’c for forming anodes by vibration-compaction are fed with carbonaceous paste by the feed device 100 comprising, in the conventional manner, a storage hopper 101 acting as a buffer between the continuous flow of paste entering the installation and the discontinuous stream of molded blocks exiting the installation, a vibrating feeder 103 located under the storage hopper 101, and a weighing hopper 104 fed a uniform supply along its length due to the motorized distribution flap 105. When the mass of paste in the weighing hopper 104 reaches a defined value, the operation of the vibrating feeder 103 is immediately stopped to prevent additional paste from being fed into the weighing hopper 104.
The manufacturing assembly additionally comprises a conveyance device 200 for conveying and distributing paste from the feed device 100 to the molds 1 of the forming machines. For this purpose, the assembly comprises a main roller track for the conveyance device 200. The main roller track is in the form of two parallel 2013231114 01 May 2017 main rails 16, as illustrated for example in the figures, which extend in a first direction referred to as the main direction.
The conveyance device 200 comprises a conveying hopper 201 supplied with carbonaceous paste by the feed device.
An assembly for producing molded blocks according to the invention is represented in figure 4, comprising three forming machines 1’a, 1’b, 1’c aligned in the main direction, and more specifically the main openings of the molds 1 of the forming machines 1 ’a, 1’b, 1’c are aligned, being understood that there can be any number of aligned molds 1.
The openings of the molds 1 are offset in a second direction, referred to as the secondary direction, relative to the main roller track 16, said secondary direction being perpendicular to the main direction. More specifically, when viewed in a horizontal plane extending in the main direction and in the secondary direction, the openings of the molds 1 are not positioned between the two rails 16 of the main roller track, but are offset to one side, in this case the side opposite the side where the feed device 100 is located, in the secondary direction.
As a result, in order to bring the paste from the feed device to the molds, the conveying hopper 201 is able to move both in the main direction and in the secondary direction.
For this purpose, the conveyance device 200 comprises a main frame 202 supporting a secondary frame 203, the conveying hopper 201 being connected to the secondary frame 203 such that the conveying hopper is secured to the secondary frame 203 in translation within the horizontal plane. In other words, the conveying hopper 201 moves translationally with the secondary frame 203 in the main direction and in the secondary direction.
In one embodiment, means for measuring the amount of carbonaceous paste contained in the conveying hopper 201 can be placed between the conveying hopper 201 and the secondary frame 203. For this purpose, the conveying hopper 201 can be connected to the secondary frame 203 by means of three supports. For example, two first supports are bearings equipped with linking means, with low friction such as metal balls or rollers, and are located on one side of the 2013231114 01 May 2017 conveying hopper 201. The third support, placed on the other side of the conveying hopper 201, can then be equipped with a force sensor, such as a spring balance, which allows measuring the amount of carbonaceous paste contained in the conveying hopper 201. When the spring balance stretches or contracts due to the weight of the amount of paste in the conveying hopper 201, the hopper then swings slightly. The means for measuring the amount of carbonaceous paste contained in the conveying hopper 201 allows ensuring that all the paste was emptied from the conveying hopper 201 into the mold 1.
The main frame 202 comprises, for example, a U-shaped framework 204, i.e. having an open side, and comprises main rolling means, cooperating with the main rails 16 of the main roller track, allowing the conveyance device 200 to move in the main direction, parallel to the direction of alignment of the molds 1. For example, the main rolling means are in the form of four rollers 205 connected in pairs, placed at the four corners of the framework 204.
The main frame 202 additionally comprises a guide 206, secured to the framework 204, defining a secondary roller track which runs parallel to the secondary direction. In practice, the guide can be in the form of two parallel secondary rails 207 extending in the secondary direction.
The secondary frame 203 is in the form of a rectangular frame, and is slidingly mounted on the main frame via the secondary rolling means 208, 209, for example rollers 208, 209, placed on what can be referred to as the front side of the secondary frame 203 and on what can be referred to as the back side of the secondary frame 203.
The secondary frame 203 can thus be moved relative to the main frame 202 by the movement of the rollers 208, 209 on the secondary rails 207 of the main frame 202.
Actuating means, such as a pneumatic or hydraulic cylinder 210, bear on the main frame 202 in order to move the secondary frame 203 in the secondary direction.
The conveying hopper 201 also comprises an opening/closing device which allows unloading the carbonaceous paste into the molds 1. 2013231114 01 May 2017
The opening/closing device is integrally attached to the conveying hopper 201, and is located for example on the lower side of the conveying hopper 201. The opening/closing device is then for example as described above, and comprises two half-shells 211 actuated by a pneumatic or hydraulic cylinder 212. In fact, as was already described above, the nature of the carbonaceous paste used in the production of anodes for aluminium electrolysis, and in particular its viscosity, requires that the opening of the conveying hopper 201 have the best possible alignment with the opening of the mold. The paste then flows more easily due to gravity.
It is understood that other solutions are conceivable, according to the nature of the paste to be poured. In fact, depending on the viscosity of the paste, the opening/closing device of the conveying hopper 201 may, for example, be an integral part of the main frame 201, such that the movement of the secondary frame 203, and therefore of the conveying hopper 201, moves the opening of the conveying hopper 203 and causes paste to be delivered into the mold 1.
As will be seen below, the secondary frame 203 and the conveying hopper 201 are placed above the rails 16 of the main roller track.
First, the conveyance device is in a retracted position, where the secondary frame 203 is retracted within the main frame 202 so that it is positioned between the two rails 16 of the main roller track. The front side of the secondary frame 203 is then facing the open side of the framework 204 of the main frame. The conveying hopper 201 is loaded with paste by bringing its upper opening level with the opening of the weighing hopper 104 of the feed device 100, which assures that the amount of paste loaded into the conveying hopper 201 corresponds to the exact amount necessary for producing a molded block.
The conveyance device 200 is then moved in the main direction by rolling the main frame 202 on the main roller track 16. When the device 200 is level with a mold 1 of a first forming machine 1’a, the movement in the main direction is stopped, and the secondary frame 203 is moved in the secondary direction so that it extends at least partially beyond the rails 16 of the main roller track. Thus the conveying hopper 201 can be shifted beyond the rails 16 of the main roller track, meaning that when viewed in a horizontal plane extending in the main direction and secondary direction, the conveying hopper 201 is not positioned between the 2013231114 01 May 2017 two rails 16 of the main roller track, but is offset to one side, in this case the side where the openings of the molds 1 are located, in the secondary direction. More specifically, the cylinders 210 of the main frame 202 are actuated to achieve this. The secondary frame 203 exits the main frame 202 through the open side of the framework 204 and, with the conveying hopper 201, passes above the rails 16 of the main roller track to avoid any interference, moving in the secondary direction on the secondary roller track by rolling along secondary rails 207 on the main frame 202.
The conveyance device 200 is now in a deployed position, where the conveying hopper 201 and its opening/closing device 211, 212 are lined up with the opening of the mold 1 of the first machine 1’a, said opening being offset in the secondary direction relative to the main roller track 16. By activating the hydraulic cylinder 212 that opens the two half-shells 211 of the opening/closing device of the conveying hopper 201, the paste is discharged into the mold 1.
In a first embodiment, illustrated in figures 6 and 7, the rollers 208, 209 of the secondary frame 203 leave the secondary rails 207 of the main frame 202 to roll over the upper surface 14 of the mold 1, until the conveying hopper 201 is positioned above the opening of the mold 1. The guides 207 of the main frame 202 are then substantially in the same plane as the upper surface 14 of the mold 1.
During the transition from the retracted position to the deployed position, the front side of the secondary frame 203 first leaves the rails 207 of the main frame 202. However, for practical reasons, the secondary rails 207 of the main frame are not directly next to the molds. For example, the production assembly may include a maintenance cart, not represented in the figures, which moves above the molds 1 in the main direction. More specifically, in practice, the production assembly comprises a third rail in addition to the two rails 16 of the main roller track, parallel to the two others, such that it forms, with one or two other rails, a branch roller track above the molds. The maintenance cart then shares a rail with the conveyance device 200, which in the case illustrated in the figures is the rail located immediately next to the molds 1.
As a result, in order to allow the maintenance cart to travel on the common rail, the conveyance device 200 in the retracted position, and more specifically the 2013231114 01 May 2017 main frame 202 supporting rails 207, must be distanced from the molds. Thus, in order to move into the deployed position, the secondary frame 203 must cross some space before the rollers 208 on the front side come into contact with the upper surface 14 of the mold 1. In order to limit the overhang for the rollers 209 on the back side as this space is crossed, the front side of the secondary frame 204 is equipped with two pairs of rollers 208, spaced apart from each other by a defined distance that is greater than or equal to the space to be crossed. Thus, when a first pair of rollers 208 of the secondary frame 203 leaves the secondary rails 207 of the main frame 202, the secondary frame 203 continues to bear on the secondary rails 207 via the second pair of rollers 208 of the front side and the pair of rollers 209 of the rear side. Then, when the first pair of rollers 208 of the front side comes into contact with the upper surface 14 of the mold, the second pair of rollers 208 of the front side can also leave the secondary rails 207.
As a variant, not represented, the production assembly comprises crosspieces extending in the secondary direction, on each side of the mold 1 of each machine 1’. The secondary frame 203 of the conveyance device 200 in the deployed position can then roll on the crosspieces in order to position the conveying hopper 201 above the mold concerned.
During the movement of the conveying hopper 201 in the secondary direction, said hopper alternates in travelling on the secondary rails 207 secured to the main frame 202, then on the edges of the upper face 14 of the mold 1 or on crosspieces arranged on each side of the mold 1, which extend the secondary roller track. The position of the secondary rails 207 secured to the main frame 202 is such that it they can be placed exactly in line with the edges of the upper face 14 of the mold or with the crosspieces arranged on each side of the mold 1.
The conveyance device 200 is then returned to the retracted position by actuating the cylinders 210 between the two frames 202, 203. By the reverse movement of the conveyance device 200 along the rails 16 of the main roller track, the conveying hopper 201 is again brought level with the opening of the weighing hopper 104 in order to be loaded with carbonaceous paste. A new cycle to convey paste to the mold 1 of another forming machine 1’b, 1’c can be started.
For example, when a machine 15b positioned between two machines 1’a and 1’c, is operating, meaning the cover 13 is sealing the mold 1, the conveyance device 2013231114 01 May 2017 200 can still move between the two machines 1’a and 1’c in the main direction without interfering with the machine 1’b that is operating.
The conveyance device 200 thus allows feeding more than two forming machines 1’ from a same feed device 100. The production rates are thus increased, while the size of the production assembly is decreased relative to a prior art assembly comprising more than two forming machines 1’.
