Device for joining flat individual parts to form a body unit, especially for furniture

The invention relates to a device for joining flat individual parts to form a body unit, especially for furniture.

In the known devices, which are referred to as body presses, the planar to be connected Side and bottom parts inserted and connected to one another by pressing. After completion of this pressing process the back wall is attached using glue or nail clips and then the finished body from the

Press and removed from the area of the press for further Assembly of items still to be brought in ^ transported.

The performance of such a body press is limited, since all the necessary operations have to be carried out in a single press. In addition, a physical exertion int connected to the work of carrying out the manufacture of the furniture body Porson.

The invention is based on the object of designing a device of the type shown so that while reducing the risk of accidents and physical exertion in a certain time unit a much higher number of furniture bodies can be produced.

According to the invention, this object is achieved in that several a multi-station unit forming body presses are rotatably mounted, with a body press a Automatic glue or nailing machine and a case press, a case removal device with a case transport belt assigned.

In a preferred embodiment, the base frame rests on a foundation frame, which is a chassis and can have a locking device, with two multi-station units on the foundation frame are arranged, which are arranged to rotate in opposite directions. The multi-station units are expedient here so arranged to each other that the respective intended for pressing the parts together Carcass presses and the carcass removal devices are arranged next to one another or facing one another.

Only one operator is required to operate the multi-station unit according to the invention even if two such multi-station units are arranged on the foundation frame.

The operator only has the individual two-dimensional Insert parts into the body press. The compression, the attachment of the back wall and the removal of the finished body from the multi-station unit take place automatically. The invention makes a high Rationalisierungseffelct achieved with a simultaneous substantial reduction of physical work and Improvement of accident protection.

_ 10 The carcass arranged in the multi-station unit * "* presses each have a fixed support and an adjustable support, the adjustable support expediently via an upper and is slidably mounted lower on a press frame rigidly arranged guide.

There is the possibility of a laterally adjustable body roll pressure device with an associated To arrange pressing cylinder, the body roll ^ jerk device on the guide of the adjustable support

is stored. This tunnel pressure device is per se only for a limited depth range on the open / ι Front of the body required because only the Stop the front doors serving studs must be pressed against the bottom and top floor. The body stud pressure device can, however, advantageously also be designed in such a length that they simultaneously serves as a support for the floor. If on both sides of the carcass stud pressure device Abutments or brackets are attached, can in

Arrangement of the gusts 52 themselves make these statements also to, d. i.e., the bottoms can also be put into a groove, a fold or flush.

The corpus stud pressure device 9 is laterally adjustable via an associated feeding cylinder 10 and on the Guide 8 of the adjustable support 7 is stored. The embodiment shown in Fig. 2 also serves as a support for the bottom 52, but is not required for the pressing of the body stud in this embodiment. The body stud pressure device 9 can also be designed as an abutment for two side walls to serve.

To adjust the depth for the side walls 51 of the body, the supports 6 are located in the mutually facing sides and 7 one or more cylinders 19, which are continuously adjustable in body depth, are arranged, with the cylinders 19 being in the supports 6 and 7, the inserted side walls 51 strike directly or indirectly against the cylinders 19.

Each support 6 and 7 has a vertically extending guide part 61 with a motor 44

Drivable longitudinal chain drive 45 pulls & assigns. Instead of the chain drive 45, a toothed rack, a cylinder, a spindle or the like can also be arranged be. On this chain drive 45 there is a guide slot 46 which runs parallel to the bottom 52 Guide rail 43 arranged. On each guide rail 43 there is a horizontally displaceable stop element 47 arranged for the side walls 51 and the floors 52, the Aaschlagelement 47 over the slot 11 is connected to a tension element. This stop element 47 can be displaced on the guide rail 43 via a motor 48 arranged at the end of the guide rail.

In order to guide the rear wall 53 in the correct position, an adjusting screw 55 is arranged on the free end face of the guide rail 43, which can be manually or electronically is adjustable. This adjusting screw 55 is one that acts on the other side of the rear wall 53 Associated counter-pressure element 60, which is arranged at the free end of a pivotable protective plate 54. That The protective plate 54 can be pivoted about the pivot point 59. In the stop position of the counter-pressure element 60, the Protective plate 54 on a contact element 58 of a limit switch 57 at. A handle 56 is assigned to the protective plate 54 for manual operation. Likewise can the fender 54 can be operated automatically.

In a variant of the embodiment, several height extensions running parallel to the floor 52 are attached to the chain drive.

Beat 62 for the corpus floors 52 and the intermediate floors 15 arranged, wherein the height stops 62 are adjustable to each other and on one end face each have an adjusting screw 55. In this variant, there is a separately drivable one for the depth stop of the body and guided stop element 63 angeordfvt. For certain versions of the body it is necessary Make the top panel lower than the bottom panel, especially when the door to be attached is on jt 10 hinge on the front of the floor and pull from the top the topsoil is to be covered. In these cases, the carcase depth is set for the sub-floor a longitudinally displaceable contact bracket 50 according to FIG. Arranged, which via an associated drive motor is movable.

The automatic glue or nailer 12 arranged in station II is at right angles on lower guides 21 to the body press 5 arranged to be movable by a cylinder or motor. The glue or nail machine has a base frame 20 on which a lower and an upper transverse guide 24 are rigidly arranged. At (_ "The transverse guides 24 are each a transverse support 23 over the cylinder 25 is mounted displaceably, the cross supports 23 connecting to one another by guides 32 are. On these horizontally displaceable guides 32 are two supports 28 displaceable in the longitudinal direction and 29 arranged. The upper support 29 is a drive motor 30 and the lower support for moving a drive motor 31 is assigned.

A nailer gun 26 and 27 is arranged on each support 28 and 29, each of which can be pivoted through 90 ° about a pivot point 33; 34 located centrally on the supports 28; 29. If the rear wall 53 of the body is to be additionally attached to the sides by means of glue or clamps, the nailer guns 26 and 27 are pivoted through 90 ° about the pivot points 33 and 34. All processes of the process, twisting and fastening, take place automatically, whereby the nail spacing can also be adjusted. A magazine * ■ 'is assigned to each nailer gun 26; 27. The light barrier 35 present on each magazine 18 enables control of the level of the filling with nails or staples in the magazine 18.

Automatic removal takes place in station III of the finished bodies. The body removal device has a base frame 36 with a guide support on. A guide track 38 for receiving a trolley 68 is arranged on the guide support 37. The trolley 68 is moved by means of the motor 39 on the guideway. There are two sides of this Veriahrwagen 68 movable suction arms 40 arranged, which with vacuum ") mammals 41 are provided.

After removing the corpus from the corpus press 5 and placing the body on a conveyor belt 14, which can run to both sides, the pivot Suction arms 40 automatically upwards by 90 ° by means of the cylinder and release the body.
