Description

In the proposed sanding machine for wooden rulers and the like of flat products, equipped with an endless sanding belt, a strap is used associated with the said belt and used to remove the bottom polished rulers from their groups placed in the store, under which to eliminate the working deflection parts of the tape placed the board.

In FIG. 1 is a side view of the machine, partly in section; FIG. 2 is a cross section of it.

The grinding belt 1 of the proposed machine (Fig. 1, 2), carrying glass paper 14 glued onto it and provided with a transverse bar 13, is located on drums 3 and 5, of which drum 3 is mounted on a common axis with a pulley 2 being rotated from the flexible gear 4, and the drum 5 is placed on racks 6, moving along the bed 7, in order to strengthen or relax the tension of the tape 1. A magazine 9 is located above the tape 1, in which groups of 10 rulers are placed to be ground, each the groups are under pressure from above the heavy plates 11, provided with lugs 12 for ease of lifting. In order to prevent the working part of the grinding belt 1 from bending, underneath the magazine 9 there is a board 8dl placed to allow the output of 9 polished rulers from the store, the walls of the latter are positioned above the tape at a height corresponding to the thickness of one ruler, and to avoid pulling out the lower rulers by polishing the tape on the wall suspended rotary shield 15, equipped with OS "spring 16.

According to the load in the store 9 of a certain number of rulers and installation above their groups of plates 11, the drum 3 is rotated, and the belt, moving as it rotates, produces the polishing of the lower rulers. When the bar 13 reaches store 9, it removes from the groups 10 through the space between the walls of the store and the tape 1, the ground polished rulers, and at the time the rulers leave the store, the shield 15 is turned under pressure from the rulers 13. Upon leaving the lower rulers of the group 10, they are lowered onto the tape under the weight of the rulers and plates 11 lying above, and their new lower rows are clipped.

Invented by the invention.

A wood sanding machine for iHbix rulers and the like of flat products, equipped with an endless sanding belt, characterized in that a cross bar 13 is connected to the belt to remove the bottom polished rulers of their 10 groups placed in the magazine 9

and under the pressure of the heavy plates 11, in which the device, to prevent the lower rulers from pulling out with a sanding tape, a rotary shield 15 suspended from the axis 16 with a spring 16 is suspended on the wall of the magazine; board 8.
