Referring now to the drawings, and more particularly to
In a molding process of molding articles, a mold (not shown) defining a mold volume (not shown) circulates, or is positioned, below a filler apparatus 10 of the molding process for receiving a moldable material (not shown), such as a wet or a dry moldable material. The wet or dry moldable material may include, without limitation, concrete, composite concrete and the like. The mold may include one cavity or a plurality of cavities having the same cavity volume or cavities of different volumes. The one or more cavities may have a plurality of different shapes such as to form a plurality of concrete articles of different shapes and configurations. These concrete articles may be installed in garden and/or driveway areas, used in the creation of landscaping designs, may be veneer products, roof tile products, building work and masonry products and the like.
In accordance with an embodiment, the mold may be conveyed via a conveyor (not shown) below the filler apparatus 10.
The filler apparatus 10 includes a main frame 16 and a filler container 18. The filler container 18 is slidably and releasably in engagement with the main frame 16 for receiving the moldable material. The filler container 18 is slidable between a first position (i.e., where the filler container 18 is being filled with the moldable material) and a second position (i.e., where the filler container 18 pours the moldable material on a volumetric container 22). The filler container 18 further defines an opening 20 for providing the moldable material to exit the filler container 18 towards the volumetric container 22 below the filler container 18. The filler apparatus 10 further includes a volumetric container 22 releasably mounted on the main frame 16 below the filler container 18. The volumetric container 22 includes one or a plurality of mold openings 24 where each mold opening 24 defines a mold opening volume 26 which is substantially equivalent to a mold volume defined by the mold (i.e., each one of the plurality of mold openings 24 corresponds to a corresponding cavity (not shown) of the plurality of cavities of the mold). Each mold opening 24 is for receiving the moldable material, which exits the opening 20 of the filler container 18. The filler apparatus 10 further includes a sliding plate 28 slidably and releasably supported to the main frame 16 below the volumetric container 22. The sliding plate 28 is slidable between a filling position and a releasing position.
In operation of the filler apparatus 10, when the sliding plate 28 is in the filling position, the sliding plate 28 blocks the mold opening(s) 24 of the volumetric container 22 to form a mold section (or mold sections) for receiving the moldable material. On the other hand, when the sliding plate 28 is in the releasing position, the moldable material may be released from the mold opening(s) 24 of the volumetric container 22, thereby allowing the moldable material to be released into the mold below the volumetric container 22 (i.e., the mold can travel below the filler apparatus 10 on a conveyor).
It is to be noted that one of the advantages of the filler apparatus 10 is that, according to its configuration, it can be assembled and disassembled very quickly and in a single sub-assembly unit for maintenance, cleaning and/or replacement procedures.
Thus, at least one of the filler container 18, the volumetric container 22 and the sliding plate 28 may be released, detached, demounted or disconnected from the main frame 16 of the filler apparatus 10. Then, the filler container 18, the volumetric container 22 and/or the sliding plate 28 may be uninstalled at any moment from the main frame 16 such as a washing and/or a repairing/maintenance process may be provided to these parts (i.e., the filler container 18, the volumetric container 22 and the sliding plate 28) of the filler apparatus 10. When the filler container 18, the volumetric container 22 and the sliding plate 28 are detached, demounted, disengaged and/or disconnected from the main frame 16, the process can still operate using alternative filler containers 18, volumetric containers 22 and/or sliding plates 28.
As shown, the filler apparatus 10 further includes a supporting plate 30 for supporting the filler container 18. The supporting plate 30 includes mating connectors 118 for releasably connecting with corresponding mating connectors 126 of a washing and maintenance support station 100 (as described below) for receiving parts of the filler apparatus 10. The supporting plate 30 may include a plurality of mating connectors 118. As shown, the supporting plate 30 has four openings 32 for connecting with the corresponding mating connectors 126 of the washing and maintenance support station 100. It is to be mentioned that is it possible to use two or more filler apparatus 10 for face mixing processes.
As also shown, the volumetric container 22 includes a frame 34, which has mounts 120 for releasably mounting to the mount receiving sections 128 of the washing and maintenance support station 100. The frame 34 may include a plurality of mounts 120 or one mount 120. As shown, the frame 34 has four downwardly extending legs 40 for corresponding with the corresponding mount receiving sections 128 of the washing and maintenance support station 100. According to an embodiment, the mount receiving sections 128 are v-shaped in order to facilitate mounting and unmounting with the mounts 120. The mount receiving sections 128 (v-shaped or not, or having another shape adapted to fulfill the same function) are also used as guides for aligning the filler apparatus 10 with the main frame 16 or the support station 100 upon engagement and disengagement of the filler container 18, the volumetric container 22 and the sliding plate 28.
As also shown, the sliding plate 28 defines a substantially flat section 36 to be received by a receiving support 38 of the washing and maintenance support station 100.
It is to be noted that the mating connectors 118, the corresponding mating connectors 126, the mounts 120, the mount receiving sections 128, the substantially flat section 36 and the receiving support 38 of the filler container 18, the volumetric container 22, the sliding plate 28 and the washing and maintenance support station 100 may be of any shape and configuration such as to correspond with a corresponding mating connector/mount receiving section/receiving support and allowing the parts (i.e., filler container 18, volumetric container 22 and sliding plate 28) to be received, engaged, connected, mounted and/or supported by the washing and maintenance support station 100.
According to another embodiment, the hook section and/or the latch section of the corresponding mating connector 126 may include a support portion 200 and an engagement portion 202 pivotally extending from the support portion 200. The engagement portion 202 is capable of pivoting relative to the support portion 200 between an engaged position where the hook section and/or the latch section of the corresponding mating connector 126 is releasably connected with the opening 20 and a disengaged position.
In accordance with another embodiment and referring now to
In operation, an operator, using a vehicle (i.e., such as, without limitation, a lift vehicle 140 with forward forks 141), a robot, a travelling crane, or an automated mechanism release the filler container 18, the volumetric container 22 and the sliding plate 28 from the main frame 16 of the filler apparatus 10. The operator needs to align the forward forks 141 of the lift vehicle 140 underneath the surface of the sliding plate 28 and to lift the parts of the filler apparatus 10 in an upwardly direction (i.e., the parts being the filler container 18, the volumetric container 22 and the sliding plate 28). Then, the operator, having the filler container 18, the volumetric container 22 and the sliding plate 28 supported by the forward forks 141 may circulate towards a washing and maintenance support station 100 which will receive these parts of the filler apparatus 10. The operator may want to release the parts from the filler apparatus 10 for washing purposes, for maintenance purposes, or simply for changing the volumetric container 22 such as to provide an alternative volumetric container 22 which have plurality of cavities of other shapes and configurations to created molded articles of different shapes and configurations.
According to another embodiment, at least one of the filler container 18, the volumetric container 22 and the sliding plate 28 may be displaced in a horizontal direction, a vertical direction, an angled direction, any combination and the like, relative to the main frame 16 of the filler apparatus 10 or to the support main frame 124 of the washing and maintenance support station 100 such as to dislodge the filler container 18, the volumetric container 22 or the sliding plate 28 from the main frame 16 of the filler apparatus 10 or from the support main frame 124.
According to another embodiment, the volumetric container mount receiving section 128 comprises a plurality of volumetric container mount receiving sections 128 for releasably mounting a plurality of volumetric container mounts 120. Each one of the plurality of volumetric container mount receiving sections 128 extends outwardly from the external frame portion 204 of the support main frame 124.
According to another embodiment, each one of the plurality of volumetric container mount receiving sections 128 may include a first plate member 206 and a second plate member 208 distant from the first plate member 206. The first and second plate members 206, 208 defines a mounting passage 210 for receiving a corresponding volumetric container mount 120.
According to another embodiment, the volumetric container mount receiving section 128 further includes a substantially flat receiving section 212 for receiving a bottom portion 214 of the volumetric container 22.
According to another embodiment, the sliding plate receiving support 38 includes a plurality of sliding plate receiving supports 38. Each one of the plurality of sliding plate receiving supports 38 inwardly extends from the support main frame 124 for defining a receiving plan for horizontally supporting the sliding plate 28.
According to another embodiment, the support main frame 124 defines a passage 216 for allowing the filler container 18, the volumetric container 22 and/or the sliding plate 28 of a filler apparatus 10 to access an internal section 218 defined by the support main frame 124.
According to another embodiment, the washing and maintenance support station 100 may be an automatized washing and maintenance support station 100 and may be, for example, designed as a dish washer, for receiving the filler container 18, the volumetric container 22 and the sliding plate 28.
Then, the operator needs to displace the forks 141 of his lift vehicle 140 such as to displace the filler container 18, the volumetric container 22 and the sliding plate 28 all together above the support main frame 124 of the washing and maintenance support station 100 and such as the mating connectors 118, and the mounts 120 of respectively the filler container 18 and the volumetric container 22 are aligned with their corresponding mating connectors 126 and mount receiving sections 128 on the support main frame 124 of the washing and maintenance support station 100. Once the parts of the filler apparatus 10 are aligned with the support main frame 124 of the washing and maintenance support station 100, the operator may drive up and down (i.e., vertically) the parts relative to the support main frame 124.
Firstly, driving up the parts relative to the support main frame 124, the corresponding mating connectors 126 (i.e., the four latches/hooks 126 upwardly extending from the support main frame 124) on the support main frame 124 will releasably connect/engage with the four openings 32 on the periphery of the supporting plate 30 supporting the filler container 18. Thus, when the operator continues by driving down the forks 141 of the lift vehicle 140, the filler container 18 will be held up by the corresponding mating connectors 126 (latch/hook sections 126) on the support main frame 124 of the washing and maintenance support station 100.
Secondly, when the operator continues to drive down the forks 141 of the lift vehicle 140, the mounts 120 (i.e., the four downwardly extending legs 120 extending from the volumetric container 22) of the volumetric container 22 will releasably mount on the four mount receiving sections (or ledges) 128 of the support main frame 124 of the washing and maintenance support station 100 (i.e., the mount receiving sections or ledges 128 outwardly extending from the support main frame 124 of the washing and maintenance support station 100) such as to provide the volumetric container 22 to introduce within the support main frame 124. Thus, when the operator continues to drive down the forks 141 of the lift vehicle 140, the volumetric container 22 will be held up by the mount receiving sections or ledges 128 on the support main frame 124 of the washing and maintenance support station 100 (i.e., via gravity forces applied on the downwardly extending mounts 120).
Thirdly, when the operator continues to drive down the forks 141 of the lift vehicle 140, the substantially flat section 36 defined by the sliding plate 28 will releasably be supported and/or be in interaction with the receiving support 38 of the support main frame 124 of the washing and maintenance support station 100 (i.e., the receiving support 38 of flat section 36 defined by the support main frame 124 of the washing and maintenance support station 100). Thus, when the operator continues to drive down the forks 141 of the lift vehicle 140, the sliding plate 28 will be hold back and supported by the receiving support 38 on the support main frame 124 of the washing and maintenance support station 100 (i.e., via gravity forces applied on the sliding plate 28).
Thus, when the parts (i.e., the filler container 18, the volumetric container 22 and the sliding plate 28) are releasably mounted on the washing and maintenance support station 100, it may be possible for the operator to wash and/or repair these parts. This allows the operator to continuously operate the molding process without having to stop the plant for maintenance.
On the other hand, when all the parts are washed and/or repaired and/or replaced, the operator may circulate with his lift vehicle 140 towards the washing and maintenance support station 100 which holds/support/connect the filler container 18, the volumetric container 22 and/or the sliding plate 28.
When the operator drives up the forks 141 of the lift vehicle 140, the substantially flat section 36 defined by the sliding plate 28 will release from (unsupported by) the receiving support 138 of the support main frame 124 of the washing and maintenance support station 100. Thus, when the operator continues to drive up the forks 141 of the lift vehicle 140, the sliding plate 28 will be supported by the forks 141 of the lift vehicle 140.
Moreover, when the operator continues to drive up the forks 141 of the lift vehicle 140, the mounts 120 (i.e., the four downwardly extending legs 120 extending from the volumetric container 22) of the volumetric container 22 will release from the mount receiving sections or ledges 128 of the support main frame 124 (i.e., the four volumetric container ledges 128 outwardly extending from the support main frame 124 of the washing and maintenance support station 100). Thus, when the operator continues to drive up the forks 141 of the lift vehicle 140, the volumetric container 22 and the sliding plate 28 will be supported by the forks 141 of the lift vehicle 140.
When the operator continues to drive up the forks 141 of the lift vehicle 140, the corresponding mating connectors 126 (latch/hook sections 126) (i.e., the four latches/hooks 126 upwardly extending from the support main frame 124) on the support main frame 124 will release from the openings 32 on the periphery of the supporting plate 30 supporting the filler container 18. Thus, when the operator continues to drive up the forks 141 of the lift vehicle 140, the filler container 18, the volumetric container 22 and the sliding plate 28 will be held back and supported by the forks 141 of the lift vehicle 140.
Then, the operator may circulate away from the washing and maintenance support station 100 and if he wants to reinstall the parts on the main frame 16 of the filler apparatus 10, he may need to align the forks 141 of his lift vehicle 140 such as to displace the filler container 18, the volumetric container 22 and the sliding plate 28 all together above the main frame 16 of the filler container 18 and such as the mounts 120 of the volumetric container 22 are aligned with their corresponding mount receiving sections 42 on the main frame 16 of the filler apparatus 10. Once the mounts 120 of the volumetric container 22 are aligned with the main frame 16, the operator may drive down the parts toward the main frame 16 of the filler apparatus 10 and drive back/forward the lift vehicle 140. The filler apparatus 10 and thus the molding process may then be used again.
It is to be noted that one or more from: the filler container 18, the volumetric container 22 and the sliding plate 28 may be releasably mounted/connected/supported from, to and by the main frame 16 of the filler apparatus 10 and the support main frame 124 of the washing and maintenance support station 100. Furthermore, it is to be mentioned that any suitable flat section 36, receiving supports 38, mating connectors 118, mount 120, mating connectors 126, and mount receiving sections 128 on the filler apparatus 10, the washing and maintenance support station 100, the filler container 18, the volumetric container 22 and/or the sliding plate 28 may be suitable such as it allows a person and/or a lift vehicle 140 to releasably connect, one or more parts of the filler apparatus 10 at the same time. It is also to be mentioned that while the flat section 36, receiving supports 38, mating connectors 118, mount 120, mating connectors 126, and mount receiving sections 128 are configured such as to allow an operator to move downwardly the forks 141 of the lift vehicle 140 to releasably connect the parts on the support main frame 124 of the washing and maintenance support station 100, it is possible that the flat section 36, receiving supports 38, mating connectors 118, mount 120, mating connectors 126, and mount receiving sections 128 are configured such as to allow the operator to move up the forks 141 of the lift vehicle 140 to releasably connect the parts on the support main frame 124 of the washing and maintenance support station 100.
According to another embodiment and referring to
According to another embodiment, the method may further include washing and/or maintaining the filler container 18, the volumetric container 22 and/or the sliding plate 28.
According to another embodiment, the method further includes engaging the parts of the filler apparatus by: displacing upwardly relative to the support main frame 124 the sliding plate 28, displacing upwardly relative to the support main frame 124 the sliding plate 28 supporting the volumetric container 22, and displacing upwardly relative to the support main frame 124 the sliding plate 28 and the volumetric container 22 supporting the filler container 18.
While preferred embodiments have been described above and illustrated in the accompanying drawings, it will be evident to those skilled in the art that modifications may be made without departing from this disclosure. Such modifications are considered as possible variants comprised in the scope of the disclosure.
This application claims priority of U.S. provisional patent application No. 61/882,128 filed on Sep. 25, 2014, the specification of which is hereby incorporated by reference.
