Description

  The present invention relates to a machining device for machining a panel-shaped workpiece, preferably at least partly made of wood, wood or the like, according to the preamble of claim 1.

Prior art The above type of machining apparatus includes conveying means for conveying a panel-shaped workpiece to be machined, and this type of apparatus further includes a pressing means having a pressing plate, whereby the machine A panel-shaped workpiece to be processed can be pressed against the conveying means. Pressing the panel-shaped workpiece ensures that the workpiece is guided during machining. The pressing plate needs to be adjusted each time according to the thickness of the workpiece to be machined. It is important here that the pressing plate should always extend essentially parallel to the conveying means in order to press the workpiece uniformly and reliably throughout the conveying and machining processes. is there.

  In the case of a machining apparatus having a relatively short length, the pressing plate is often adjusted by a central movable table provided with an adjusting spindle. However, in the case of a machine having a relatively long length, the force acting on the pressing plate becomes larger, and a plurality of guide mechanisms having a spindle associated with the pressing plate are required. These spindles are typically driven in the center by common drive chains and chain wheels (sprockets) or by a set of intermediate shafts and bevel gears or worm gears. As a result of this configuration, the structural design becomes complicated and undesirable.

DESCRIPTION OF THE INVENTION The present invention is based on the problem of providing a machining device of the type described above, which has a simple design and is comparable in conveying means and pressing means and / or pressing plates. Even when the target is long, the pressing plate can be adjusted.

  According to the invention, this problem is solved by a machining device according to claim 1. In particular, advantageous embodiments of the invention are described in the dependent claims.

  The invention is based on the concept of adjusting the pressing plate with components that undergo simple linear motion, so that an adjustment spindle that is completely different from the previous approach is used. For this purpose, the invention foresees that the guide means of the preamble-based machining device has at least one inclined guide member provided slidably with respect to the pressing plate, the guide member comprising: It has an inclined guide surface extending at an angle in the direction of conveyance of the conveying means.

  In this way, components required in the prior art such as chain wheels, intermediate shafts or bevel gears and / or sets of worm gears may be dispensed with. This greatly simplifies the structural design of the machining device according to the present invention, and at the same time enables accurate and reliable adjustment of the pressing plate.

Further features and advantages of the present invention will be more effectively described based on the following detailed description of the preferred embodiments.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS In the following, various preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  A machining apparatus 1 according to a preferred embodiment of the present invention is schematically shown as a partial perspective view in FIG. Although not shown in more detail here, the machining device 1 is used for machining panel-shaped workpieces made of, for example, wood, wood or other composites. Thus, examples of panel-shaped workpieces may include furniture front panels, work tables, and work surfaces or the like.

  First, the machining apparatus 1 has a conveying means 2 in the form of, for example, a belt conveyor or a chain conveyor for conveying a plate-shaped workpiece to be machined. Above the conveying means 2 is a pressing means 4. Since the pressing means has a pressing bar (plate) 6, it is possible to press a panel-shaped workpiece to be machined against the conveying means. More precisely, in this embodiment, since a plurality of pressing rollers 16 are provided on the pressing plate 6, a conveying gap for a panel-shaped workpiece is formed between the pressing roller 16 and the conveying means 2. The

  The pressing means 4 is connected to the conveying means 2 via holding means 8 in the form of two essentially U-shaped supports.

  Although not shown in the drawings, in the case of the machining apparatus 1 of the present invention, a machine tool or a machining assembly for machining a panel-shaped workpiece is provided along the conveying means 2. Examples of these machine tools or machining assemblies include edge banding assemblies, flush milling assemblies, scrapers, or any other type of suitable assembly for machining the above panel-shaped workpieces. Articles or tools may be included.

  In this embodiment, the guide means designed to guide the pressing plate 6 in the direction of running perpendicular to the transport direction of the transport means 2 is arranged between each of the pressing plate 6 and the support 8. The

  In this embodiment, as a result of providing the guide groove 13 in the pressing plate, the guiding means has two inclined guide members 10 and 12 that are slidable with respect to the pressing plate 6. The inclined guide members 10 and 12 each have inclined guide surfaces 10 ′ and 12 ′ extending at an angle in the direction of conveyance of the conveying means 2. In this embodiment, the inclined guide surfaces 10 ′, 12 ′ have an angle of about 40 ° with respect to the transport direction of the transport means 2.

  The guiding means also includes two sliding members 10 ", 12", in this embodiment the sliding member is designed as a sliding block and is tilted by one sliding surface or It is arranged to contact or slide along twelve inclined guide surfaces 10 'or 12'. The sliding members 10 ", 12" are securely connected to the holding means 8 and each pass through the opening 6 'towards the inclined guide surfaces 10', 12 'of the inclined guide members 10, 12; The opening is provided in the pressing plate 6.

  As best seen in FIG. 2, the opening 6 ′ extends essentially perpendicular to the lower end of the pressing plate or in the direction of conveyance of the conveying means 2. Furthermore, these openings 6 ′ and sliding members 10 ″, 12 ″ are slidable relative to at least one sliding member 10 ′, 12 ′ in the direction in which the pressing plate 6 extends. Are adapted to each other.

  As can best be seen from FIG. 1, the machining device 1 according to the invention further comprises adjusting means 14, in this embodiment the adjusting means has a spindle and is inclined with respect to the pressing plate 6. 10 and 12 are designed to move or fix. Therefore, by rotating the spindle, the inclined guide members 10 and 12 are pressed so that an appropriate transfer gap between the pressing plate 6 and the transfer means 2 is adjusted for each panel-shaped workpiece. Move relative to the plate 6. Since the sliding members 10 ″ and 12 ″ slide along the inclined guide surfaces 10 ′ and 12 ′, the inclined guide members 10 and 12 move up and down together with the pressing plate 6. Therefore, the height of the pressing plate 6 can be accurately adjusted so as to be essentially perpendicular to the conveying means 2 without requiring a complicated conveying mechanism.

It is a figure which shows schematically the fragmentary perspective view of the 1st part of the machining apparatus which is an Example with this invention. FIG. 2 schematically shows a more detailed partial view of FIG. 1. FIG. 2 is a partial perspective view of different parts of the machining apparatus of FIG. 1.
