- In particular, the present invention relates to a machine to drill into panels made of wood or the like of the type comprising an elongated base extending in a first, substantially horizontal direction; a roller support device, which is mounted on the base so as to define a support surface for the panels; a feeding device to feed the panels along a feeding path extending between a panel loading station to load the panels onto the roller support device and a panel unloading station to unload the panels from the roller support device; and a drilling station obtained along the panel feeding path.
- The feeding device generally comprises at least one clamp member, which is mounted and configured so as to grab and hold the panels in the area of a side of theirs parallel to the first direction and is movable along the base in order to feed the panels on the roller support device and through the drilling station.
- The drilling station is normally provided with at least one drilling head comprising a plurality of lower vertical drill bits, which are mounted under the support surface, a plurality of upper vertical drill bits, which are mounted above the support surface, and a plurality of horizontal drill bits.
- The horizontal and vertical drill bits generally are movable in a second, substantially horizontal direction, which is transverse to the first direction, and in a third, substantially vertical direction, which is orthogonal to the panel support surface.
- In use, holes are vertically drilled into each panel by moving the vertical drill bits in the third direction and holes are horizontally drilled into each panel by moving the panel in the first direction.
- Machines to drill into panels made of wood or the like of the type described above are affected by some drawbacks, which are mainly due to the fact that the configuration of the drilling head and the combination of the movements of the panel in the first direction and of the horizontal and vertical drill bits in the aforesaid second and third directions allow users to drill into one single panel at a time, hence ensuring a relatively small productivity.
- Furthermore, since horizontal drilling is carried out by moving the panels in the first direction and, hence, without locking the panels on the support surface, machines to drill into panels made of wood or the like of the type described above feature a relatively limited precision.
- The object of the present invention is to provide a machine to drill into panels made of wood or the like, which is designed to eliminate the aforementioned drawbacks in a straightforward, relatively low-cost manner.
