invention description

a) Title of the invention;

Device for automatically attaching strips, primarily on fan-shaped furniture parts

b) Field of application of the invention;

By means of the device according to the invention, a mechanical fastening of strips, in particular blow bars, for example on cabinet doors and the linking of the individual work steps to a continuous automatic assembly machine is achieved, which can be used both independently and concatenated within a processing line.

c) Characteristics of the known technical solutions

There are known mechanical devices in which the bar to be mounted from a mounted above and across the main transport direction magazine arranged in. the mounting position is added, after, inserted below by means of a pneumatically acting transport system, the furniture part to be equipped, positioned and stretched. Placing and fastening the strip

then follows by means of known, automatically acting screwing tools. By the subsequently supplied furniture part, the assembled assembly is pushed on and removed from the device · These devices are liable as disadvantages the restrictive use of only short ,, relatively stable and stiff perform as well as the screwing as a fixed working method, with unreasonable long processing times arise. Furthermore, by pushing the strip on the surface quality defects in Porm occur. of blisters, uneven glue application and cavitation. Bs devices are still known in which at stationary workstations, the workpieces to be joined, primarily plates frame or blocks, inserted by hand, determined and connected by manually operated spindles or pneumatically acting plunger. The bonding agent used is primarily slow-setting adhesive. Here, the high manual outlay, the insufficient work performance, the different quality and the large space requirement for installing a frequently required multiplicity of devices have proven particularly disadvantageous.

ά.) Object of the invention

The object of the invention is to provide a device which ensures that strips of different materials. Strength and dimensions in the automatic workflow effectively and in good quality primarily on 'flat. Furniture parts are attached ..

e) Presentation of the essence of the invention

The invention has for its object to perform the device so that by the basic arrangement of certain components attaching strips on. Mo-

through the use of effectively acting connection means is achievable, v / if the Higeproseß accelerated by means of force on the materials to be joined

According to the invention the object is achieved in that for receiving the afford stack a known per se Sch eight magazine and a consisting of supports, driver, feed carriage, rack shaft and gear feed unit are provided and with a printing device consisting of a plurality linear aligned, individually driven and depending on the strip length usable, oscillating bearing plunger with positive or cohesive determination and Haiteelementen, which is associated with the furniture parts expiration feeding Haupttransportsystem, is in operative connection, that the _ connecting means, in particular hot melt adhesive, intermittently or continuously on the furniture panels applied and then compressed according to load until complete connection.

The puncture of the device according to the invention is that the inguinal stack in a shaft magazine, which is verstel Ibar in the plane verstel Ibar is entered, from which cyclically below arranged separately guided, but jointly driven mechanisms pass the scattered bar sideways leading a printing device while the remaining ingot stack in the shaft magazine rests on separate stationary supports relieving the individual whirling mechanisms. In accordance with the procedure, the workpieces to be assembled, in particular furniture doors, are supplied by means of a main transport system assigned to the technical device, determined in position by movable, adjustable stops and secured by means of pressure arms. The bonding agent, primarily hot melt adhesive, is applied to the door intermittently or continuously during feeding. The printing device performs at the same time or by a downward movement of the individual plunger in a programmed order, in particular at

flexible, long and thin materials, the bar positionally correct on the door and compresses the workpieces "to complete connection together * The" special advantages of the invention are to be seen therein »that due to the application of advanced processing methods, a significant increase in performance over the known devices Manpower savings and the use of different materials and sizes are achieved and by the fixed, program-specific pressing of the parts all previous quality defects are resolved ·

f) embodiment

The invention will be explained in more detail below using an exemplary embodiment. The accompanying drawings show:.

J thirty. 1 :. Sectional diagram of the entire device. 2: - Basic arrangement of the printing device

The last stack 1 is entered into a slot magazine 2 and supports supports 3 arranged thereunder. This is followed by the transfer of the isolated strip 8 to the printing device 4 by means of the feed carriages 5. The door β is fed from the main transport system 7 below the stand-by bar 8 and at the same time by means of a separate applicator 9 with hot-melt adhesive; * coated. Subsequently, the bar 8 is pressed: and then removed the finished assembly.

The Jhinktionsweise the entire facility is the following:

In an adjustable shaft magazine 2 of the last pile. T inserted «Singulation at the lower end of the shaft magazine. 2 takes place automatically. A plurality of feed carriages 5 arranged in parallel over the entire length of the shaft magazine 2 are each provided with a spring support

th, tiltable driver 10 equipped, both in one direction of movement, the inguinal stack 1 can move under unhindered, as well as in the opposite direction, the Mitneher 10 you rch a snap up the lower bar 8 from the. Leistenstapel 1 pushes and transported on the feed carriage 5 to the printing device 4, while remaining in the shaft magazine 2 rest dss ingot stack 1 rests on the stationary supports 3. The tactual feeding the bar S to the printing device 4 takes place. by pressing z. B. a working cylinder, a rotatably mounted shaft 11 is driven, the form-fitting manner, for example via gear 12 and rack 13 with each arranged between the pads 3 feed carriage 5 is in a squeegee. At the same time, by means of the independently driven main transport system 7, the door 6 is passed under an unspecified hotmelt applicator 9, coated in the defined area with hotmelt adhesive and at a short distance below the in.. Pressing device 4 by means of vacuum actuated Adhesive mechanisms or similar held bar 3 is positioned. By adjustable lateral guides 14 and from above on the door leaf, pressing spring-loaded pressure arms 15 and a dimensionally coordinated with the bar 3, the door leading edge determining and tactically acting stop 16, the main transport system 7 is added functionally reliable. The pressing of the bar 8 on the door β is carried out by means of individual ordered guided and driven plunger of the printing device 4 which in programmie cal HeihenfolgB are successively operated. The thus causing bending of the bar 8 is compensated by means of the pendulum-mounted plunger of the printing device 4. The forces introduced during the pressing process are intercepted by means of a support rail 17 provided underneath the door 6. Compartment for relaxing and releasing the stop 16 becomes the. finished assembly removed by means of the main transport system 7.
