CZ2000662A3 - Edge processing machine - Google Patents

Abstract

The edge working machine has a machine stand (1) for machining devices (2-4) and chain tracks (5) carrying the workpieces to them. The stand consists of at least two modules (11,11') one behind the other in the feed direction of the chain tracks. Each module has a cavity (11b) for the machining devices and mirror-image endfaces (11a) with flange surfaces, borings and a centering groove for a centering bar (19).

Description

The invention relates to an edge processing machine for strip-shaped or plate-shaped workpieces with a machine stand for mounting machining devices for machining the workpieces and an endless chain conveyor carrying the workpieces for their sequential transport to the machining device.

Current.........state.......technical quality

In the case of these machines with a frame stand design, this may be a finishing device, edge banding device, grinder, drill, etc. The length of such machines depends primarily on the number and type of machining devices arranged one after the other in the direction of workpiece travel.

The essence.....is the climb

The object of the invention is to provide the above-described edge processing machine with a design that enables simple, fast and inexpensive production of machines of various lengths.

This object is achieved according to the invention in that the machine stand consists of at least two modules arranged in the conveying direction of the chain conveyor, each module comprising an interior space for accommodating machining devices and having mirror-image fronts with flanges and also a centering groove for fastening or aligning an integrated linear bearing assigned to the chain conveyor and surfaces and flange bores for mounting the centering bar for the adjacent module, and for chain guide bars also connections for mounting the drive sprocket and the tensioning sprocket.

In this case, the module according to the invention can be designed only as an extension of the lower part.

If only two modules of different lengths, for example 1000 mm and 1500 mm, are selected as basic elements, then machines with different lengths of their chain conveyors can be produced without any problems by means of the appropriate combination. If, in addition, a modified module is created in the form of a lower section extension with, for example, only three different lengths of 500 mm, 1000 mm and 1500 mm, then almost any structure required in practice can be assembled together with the basic modules into an expandable system with a basic size and screw bearings. This results in a chain guide that is independent of the length of the chain wheels. If only two construction sizes are created for the module, only two construction sizes are also required for sound insulation and for the generally identically designed center cross-sections of the device. The production costs are reduced compared to existing designs, and production is also possible independently of the order and also independently of the aggregates. Based on the design according to the invention, the customer has the option of expanding the edge processing machine, if necessary, by means of a problem-free extension of the machine stand at one or both ends.

Even with a completely new concept, the modules can be used in a converted system. In addition, in the event of partial wear, for example in the chain guide, it is not necessary to replace the entire chain conveyor, but only a segment of the module.

Further features of the invention are the subject of the dependent claims and are explained in more detail in connection with further advantages of the invention by means of exemplary embodiments.
