Description

;: When working on woodworking machines, uninterrupted supply of blanks to the feeding mechanism and automation of the feeding process are essential. According to the invention, a magazine is offered for receiving blanks and feeding them to a feeding mechanism in which two plates are used, one of which serves as guides when feeding blanks and the other is connected with a slide-carrying carriage with blades for gripping blanks on one of the store and transfer them under the nutritional rollers.

In FIG. 1 shows a perspective view of a magazine and a machine in which it is applied; FIG. 2-side view of the store; FIG. 3-cross section of the guide ruler.

In the front part of the proposed magazine (Figs. 1 and 2) on inclined guides 7 of the turning type, there is a vertical shield 2 mounted on one slide with a rotating drum 3 equipped with blades moved with screws 4 by means of an ejector wheel 5. Guides / have a side scale b with divisions.

On the machine bed, the fixed frame 8 is also fixed, in which it is placed with possibility of movement in the ver (258).

In the ticking direction, the flap 7, hinged to the rulers 9, which are reinforced in turn, is hinged using screws 7 / on the flap 2. The distance between the machine table at which the magazine is applied and the lower edge of the flap 7 is controlled by the steering wheel W, and 7 is fixed in a certain position with the help of the spur wheels 72. Behind the frame 8 supporting the shield 7, the feed rollers 75 and J4 are located, of which the rollers 75 are made grooved along its axis of rotation and mounted on ball bearing supports; rivers its axis of rotation and fastened at an angle to the axis of rotation of the rollers 75. The nutrient Adjacent the nutrient rollers mounted on the machine table perestavnye guide line 75 and J6, having a cross section corresponding to the profile of the workpiece (FIG. 3). The saws 36 and 57 of the machine are fixed on the shaft 38 with the possibility of adjusting the distance between them. The whole feed system rotates from the engine through the transmission (not shown); the drum 3 is transmitted through gears 4} and toothed tension roller 42, which are connected to each other by means of

Gall chains 43. The reversal of the direction of rotation of the feed system is accomplished by installing a cross-belt. Before starting work on the machine, in which the proposed magazine is applied, the flap 2 (Fig. 1, 2) using the spindle wheel 5 is set according to the length of the workpieces according to the scale divisions 6, with the flap 7 fixedly fixed by the steering wheels 12, and the ruler 9 on the shield 2 by loosening the screws 7 /. By installing the flap 2, the screws 7 / are fixed, and the handwheels 72 are loosened and with the help of the helm W, the distance between the flap 7 and the machine table is set according to the thickness of the board. In accordance with the thickness of the boards, guide bars 75 and 16 are also installed. At the end of these preliminary measures, boards are loaded into the store (Figs. 1, 2). The bottom board is picked up from the magazine by the blade of the drum 3 and extends toward the rollers 75. At the time of pulling out the board, the shield 7 rises a little and when the board is lowered to the horizontal position it descends again. The end of the second board, located at the flap 2, cannot be lowered onto the blades of the drum 5 until the first plaque passes the flap 7, after which the second plaque is lowered onto the machine table and onto the drum 3 and is also fed after the first. Thus, the boards are fed one after the other to the rollers 75, J4, from where the boards, guided by the ruler 75, go to saws 36 and 57, where they are trimmed.

The subject matter of the invention.

A magazine for receiving workpieces and feeding them to the feeding mechanism in woodworking machines, characterized by the use of two plates 2 and 7 j of which the plate 7 is placed in the fixed frame 8 and made up and down, and the plate 2 is fixed with a movable screw 4 along the guide rail, bearing drum 3 with blades designed to grip the blanks at one of the magazines and transfer them to the feed rollers 75 and J4.
