Description
FORMING AND FEEDING ASSEMBLY FOR A SHEET hATERIAL PRESS
The invention relates to sheet material presses and especially to a forming and feeding assembly for a sheet material press used in the production of decorative and industrial laminates of fibre-reinforced resin systems and for the finishing of chipboards, fibreboards and the like with layers of synthetic resins applied to a surface thereof.
Prior art forming and feeding assemblies include an assembly table on which the laminate components are combined to form a substantially rectangular mat of material to be compressed, and a feeder assembly for moving the mat to a press. The feeder assembly includes feeder arms having mat clamping members, which arms are movable back and forth in a direction of feed of the assembly. The mats of uncompressed material are gripped by the clamping members, transported into an open sheet material press by the feed stroke of the feeder arms and released after being inserted into the press. The assembly may be constructed so that the clamping members tension the mats during the feed stroke and then move towards each other to permit the mats to sag within the open sheet material press. The edges of the mats gripped by the clamping members then being released to essentially achieve a rolling out of the mats on the press table.
This substantially prevents floating of the mats while they are being positioned on the press, which interferes with the exact positioning of the mats in the press.
The term "laminate components" within the framework of the present invention includes, for example, woven and/or non-woven fibreglass pre-impregnated with synthetic resin, especially epoxy-base resin. The synthetic resin employed for impregnation is generally in a pre-polymerized or partly polymermized condition and is completely polymerized to its final condition through the use of pressure and heat. The term "laminate components" further includes foils, for example, metal foils, for the production of industrial or decorative laminates, for example, for the finishing of chipboards and fibreboards or the like. Thus, a mat of uncompressed material may also include a generally thin chipboard, fibreboard or the like, and a fini chin~ layer.
In prior forming and feeding assemblies, the assembly table is located i ~ tely adjacent the sheet material press. This arrangement is disadvantageous. Uhen the laminate components are manually stacked and adjusted to correct their orientation in superposition the feeder arms, which are mounted along the edges of the assembly table, interfere with these operations. This contributes to unsatisfactory and extended cycle times. In fact, the cycle times in prior art assemblies are dependent to a lesser degree on the press time than on the time required for the assembly of the uncompressed mats.
These disadvantages are overcome with a forming and feeding assembly for a sheet material press in accordance with the invention, which includes a transfer platform that is located between an assembly table and a sheet material press. The transfer platform can be raised and lowered from the level of the assembly table to the level of the feeder arms carrying the clamping members. The feeder arms reciprocate between the sheet material press and the transfer platform. A transfer bridge, which is reciprocally movable on the feeder arms, moves assembled mats from the assembly table to the transfer table. The transfer bridge includes gripping arms which are positioned parallel with the direction of movement of the feeder arms for selectively gripping an end of a mat on the assembly table, pulling the mat onto the transfer platform and releasing it.
It is an advantage of the present invention that the assembly of the laminate components to form an uncompressed mat may be readily achieved without interference from by the feeder arms and their clamping members, which are mounted along the sides of the transfer platform rather than the sides of the assembly table as in prior art constructions. Uhen laminates are formed using equipment in accordance with the present invention, cycle times are more dependent on press times than on the mat assembly time.
It is an object of the invention to provide a forming and feeding assembly of a construction as described above so that the layering of the laminate components may be easily achieved within a reasonable time period and with accurate orientation and superposition.
Accordingly, the invention provides a forming and feeding assembly for a sheet material press for the production of decorative or industrial laminates of fibre or filament reinforced resin systems and for the finishing of chipboard or fibreboard with layers of synthetic resin applied to a surface thereof, comprising:
an assembly table for permitting the assembly of laminate components to form a mat of material to be compressed, the mat having a substantially rectangular layout; and a feeder apparatus having feeder arms which carry clamping members for selectively gripping the edges of the mat;
the feeder arms being reciprocally movable in a direction of feed of the assembly for transporting a mat gripped by the clamping members into the open sheet material press.
The feeder apparatus further includes a transfer platform positioned between the assembly table and the sheet material press, which transfer platform is selectively positioned at the height of the assembly table or the height of the feeder arms. The feeder arms are reciprocally movable along the transfer platform. A transfer bridge having gripping arms which extend towards the assembly table parallel with the direction of movement of the feeder arms, selectively grips an end of an assembled mat from the assembly table and pulls the mat from the assembly table to the transfer table. The transfer platform is positioned at the height of the assembly table while the mats are moved from the assembly table to the transfer platform.
In a preferred embodiment of the invention, the transfer platform is provided with notches spaced-apart along its longitudinal edges, which notches are overlapped by an uncompressed mat on the transfer platform. The clamping members of the feeder arms are movable into the notches for gripping the edges of a mat when the transfer platform is at the level of the feeder arms. In a first embodiment of the invention, a platform section of constant level may be positioned between the transfer platform and the assembly table, which platform section extends towards the assembly table. The transfer platform may be mounted on a hydraulic ram or a hoist for raising and lowering it.
In another preferred embodiment, the assembled mats on the assembly table are readily and securely moved to the transfer platform over a tiltable intermediate table which is intermediate a platform section of fixed height and the assembly table. The intermediate table is provided with a table top, which in its elevated condition is downwardly inclined in the direction of feed, and includes grooves for accommodating at least part of the gripping arms of the transfer bridge to permit those arms to reliably grip an end of the mat.
The invention will now be further described by way of example only and with reference to the following drawings, wherein:
Fig. 1 illustrates a longitudinal cross-sectional view of a forming and feeding assembly in accordance with the invention;
Fig. 2 is a top plan view of the assembly shown in Fig. l;
Fig. 3 shows an enlargement of an area indicated by reference A
in Fig. l; and Fig. 4 is a top plan view of the area indicated by reference A in Fig. 1.
The preferred forming and feeding assembly in accordance with the invention as illustrated in the drawings is used for loading a sheet material press 1 during the production of decorative or industrial laminates of fibre or filament reinforced resin systems or during the finishing of chipboards, fibreboards and the like with a layer of synthetic resin. The sheet material press 1 is partially shown on the right-hand side of Fig. 1. The preferred embodiment of the invention includes a feeding apparatus 4 and an assembly table 2 on which laminate components are stacked to form a mat 3 of material to be compressed, which mat has a generally rectangular layout. The feeding apparatus, generally referred to by reference numeral 4, includes feeder arms 5 which are reciprocally movable in the direction of feed of the assembly, as indicated by a double arrow in Fig. 2. The feeder arms 5 include clamping members 6. A mat 3 is gripped by the clamping members 6, picked up by the feeder arms 5 and transferred into the open sheet material press 1 during each feed stroke of the feeder arms 5. The mat 3 is released by the clamping members 6, once the mat is positioned in the press. The feeding apparatus is constructed so that the clamping members 6 tighten a mat 3 during the feeding stroke of the feeder arms. Subsequently, the clamping members 6 may be moved towards each other so that the mat 3 sags between the feeder arms 5 in the open sheet material press 1. The clamping members 6 thereafter release the mat 3 so that the mat 3 rolls out on the press table 7.
This step prevents the entrapment of air under a mat being placed on the press table and thus helps prevent the mat from floating over the table when it is released. The mat 3 may be raised or lowered prior to this step.
The movements of various parts of the assembly described above are indicated by arrows. Of course, it will be readily apparent to a person skilled in the art that appropriate drives and controls are required for the operation of the assembly in accordance with the invention, which drives and controls have been omitted from the drawings for clarity and ease of underst~nding.
A transfer platform 8 is positioned between the assembly table 2 and the sheet material press 1, which transfer platform can be raised and lowered between the height of the assembly table 2 and the height of the feeder arms 5 and their clamping members 6. The feeder arms 5 are reciprocally movable in a direction of feed along the sheet material press 1 and the transfer platform 8. A transfer bridge 9 which is reciprocally movable on the feeder arms 5 is provided with gripping arms 10 which extend toward the assembly table 2, parallel with the direction of movement of the feeder arms 5. The transfer bridge 9 is movable relative to the feeder arms 5 to permit an assembled mat to be gripped by the gripping arms 10 and pulled from the assembly table 2 to the transfer platform 8. The forming and feeding assembly is constructed to permit transfer of a mat 3 held by the gripping arms 10 to the transfer platform 8 by movement in the direction of feed of the transfer bridge 9 and the feeder arms 5. The mat 3 is released onto the transfer platform 8 when the transfer platform 8 is at a lowered position. Once again, the movements of various parts of the assembly are indicated by double arrows. Each Z037;~30 movable part requires at least one appropriate drive and control, which are not illustrated.
Turning now to Figs. 2 and 4, it is apparent that transfer platform 8 is provided with notches 11 along its longit~ldin~l edges, which notches 11 are overlapped by a mat 3 placed on the platform 8.
The clamping members 6 of the feeder arms 5 are moved into the notches 11 for gripping the longitudinal edges of the mat 3, after the transfer platform 8 has been raised to the height of the feeder arms 5. A platform section 12 of fixed height is positioned between the transfer platform 8 with the assembly table 2, the function of which is described below. The raising and lowering of the transfer platform is achieved by a lifting mech~ni~ 13 (see Fig. 1), which is preferably a lazy tong mechanism powered by hydraulic ram, or a hoist.
A downwardly tiltable intermediate table 14 is positioned between the platform section 12 of fixed height and the assembly table 2. The intermediate table has a table top 15, which is downwardly inclined in the direction of the assembly. Table top 15 is provided with grooves 16, which accommodate a lower jaw of the gripping arms 10 of transfer bridge 9 to facilitate the gripping of an end of a completed mat on the assembly table. As is apparent from an inspection of Fig. 3, the assembly table 2 is easily accessible from all sides when the intermediate table 14 is in its downwardly tilted position, facilitating the stacking of the laminate components and expediting the st~cking of the components. The lower jaws of the gripping arms 10 are moved into the notches 16 for easy and precise pick up of the end of mat 3. Thus, very short cycle times may be achieved with a forming and feeding assembly in accordance with the present invention.
Various other constructions and realizations are possible within the framework of the invention and will be readily apparent to a person skilled in the art.
