DD286321A5 - ARRANGEMENT FOR THE AUTOMATIC COMPRESSION OF WOOD MATERIAL COMPONENTS - Google Patents

Abstract

The erfindungsgemäaesze arrangement for automatic pressing of wood-based components is used in the woodworking industry, where decorative elements are applied to furniture fronts with glue. The garment component (1) is prepositioned and held without glue in the alignment line of the pressing process (8), the decorative element (10) outside the alignment line of the pressing process (8) glued with a hot melt adhesive applicator with Duese (15) and in the alignment line of the pressing process ( 8) the press retracted, pressed and anschlieszend in the entrance level of the trim element * which is also the extension plane of interconnected Traeger components (1) and decorative elements (10), extended and removed.

Description

The furniture front is inserted into the component supply and then automatically retracted into the press without glue, positioned in the alignment line of the pressing and held. The decorative element is placed in the carriage, which is located outside the alignment line of the pressing of the press under an automatic hot melt adhesive applicator with nozzle and accurately positioned. After inserting the decorative element arranged above Leimauftragdüse moves automatically, according to the contours of the decorative element and carries the glue bead on. The glue application device runs in a one-dimensional movement and with the carriage the second dimension is realized.

After completion of the glue application, the trim element moves into the press and is positioned and secured in the alignment line of the press cycle. Thereafter, the Verprassen the carrier component with the decorative element along the alignment line of the pressing process. After a pressing time, the holding elements solve the positioning of the carrier component, the carriage moves in the entrance level of the decorative elements and the interconnected components can be removed.

AusfOhrungsbelsplel

An illustrated in Fig. 1 support member 1 is inserted with its front side 2 in the component feeding device 3 and moved with the direction of movement 4 in the entrance plane 26 against the stop 5 on the upper pressure bar 6 of the press. The holding elements 7 on the upper pressure bar β clamp the carrier component 1 and position it in the alignment line of the pressing process 8 with the back 9 at the upper pressure bar 6. Thereafter, the component feeding device 3 moves with the direction of movement 4 in the entry level 26 back to its starting position.

The decorative element 10 is inserted into the carriage 11, v / elcher is in the forward position 12. Thereafter, the carriage 11 travels in the entry level of the trim element 27 in the carriage guide 13 to the middle position 14 and stops under the hot melt application device with nozzle 15. The hot melt application device with nozzle 15 is connected via a heated, flexible glue hose 16 to a hot melt applicator 17 and to a nozzle holder 18 on the trolley 19 attached, with a glue bead 20 is applied. The second dimension in the movement is realized by the carriage 11 in the entrance level of the decorative element 27, which moves to the width of the decorative frame B on the carriage guide 13. Through the combination of both movements, a closed sequence of the hot-melt adhesive application device with nozzle 15 corresponding to the contour of the decorative element 10 is achieved. After applying the glue bead 20 on the decorative element 10 of the carriage 11 moves from the middle position 14 on the carriage guide 13 in the entrance level of the decorative element 27 against the rear stop 21. With the index pin 22 of the carriage 11 in the rear position 23 in the Alignment line of the pressing process 8 and positioned and held in the entrance level of the decorative element 27. After a pressing time open the holding elements 7, the pressure cylinder 28 moves the upper pressure bar 6 with the holding elements 7 and the stopper 5 in the pressure bar guide 24th in the starting position.

The index pin 22 is released, the carriage 11 moves on the carriage guide 13 in the extension plane 27 to the front stop 25 in the front position 12 in which the connected components, the support member 1 and the decorative frame 10 are removed. Thereafter, the process is repeated.

Claims (3)

1. An arrangement for the automatic pre-pressing of wood-based components with Schme 'adhesive for a support member and a decorative element, wherein the glue application is made by means of a glue nozzle, which is connected to a heated, flexible glue hose, and the glue application is two-dimensional, characterized in that the carrier component (Din the alignment line of the pressing process (8) in the press without glue prepositioned and held. 2. Arrangement according to claim 1, characterized in that the decorative element (10) positioned outside the alignment line of the pressing operation (8) of the press and glued and then positioned and pre-pressed for pre-pressing in the alignment line of the pressing process (8) of the press and then for pre-pressing in the alignment line of the pressing process (8) is retracted into the press. 3. Arrangement according to claim 1 and 2, characterized in that the entry level (26) of the support member (1) over the entrance level of the decorative element (27) is arranged and the entrance level of Zierelemontes (27) at the same time the extension plane of the pressed together support components (1 ) and decorative elements (10). For this 1 page drawing Field of application of the invention The inventive arrangement for the automatic Verprassen of wood-based components found in the woodworking industry, when gluing decorative elements on furniture fronts, application. Characteristic of the known state of the art Decorative elements, especially decorative frames, are applied with cold glue in the furniture industry and remain in place for a long time Press, until a corresponding liability has occurred. They can also be pinned in addition. In certain applications decorative elements are also shot with brackets. The application of hot melt adhesive from guns by hand to the corresponding components is also known. Furthermore, there are devices that connect wood panels frontally or longitudinally. A two-dimensional application of adhesive, as 4S is required for decorative frame, can not be realized with it. Ref. DE 3118029 A1
