Description

The invention relates to devices for single-piece feeding of workpieces to woodworking machines, in particular, to machines of a semi-automatic line for producing single-layer slatted floor shitos, and can be used in the forestry and woodworking industry.

The purpose of the invention is to increase productivity by eliminating distortions in the feeding of blanks.

FIG. 1 shows a diagram of the device, a plan view; in fig. 2 shows section A-A in FIG. one.

The device for single-piece feeding of workpieces to a woodworking machine consists of a bed 1, a feed 2 and a feed 3 conveyors, a table 4, which is the upper part of the bed 1, a cutter 5 and a drive 6.

The cutter 5 is made in the form of a spring-loaded two-arm lever 7 L-shaped, mounted on the hinge 8. Its one arm 9 touches the surface of the table 4 and makes an acute angle with the longitudinal axis of the feeding conveyor 3. The second shoulder 10 makes an obtuse angle with the axis of the feeding conveyor 3 and a spring 11

is raised above the table 4 so that between it and the surface of the table 4 is formed a gap exceeding the thickness of the workpiece 12.

The feeding conveyor 3 is made in the form of a chain conveyor with a leading 13 and a driven 14 asterisks, a chain 15 with stops 16 and a torque limit clutch 17. On the table 4 there is a stop-guide 18.

The device works as follows.

The blanks supplied by the brush along the feed conveyor 2 are fed to the G-shaped lever 7, which can pass the workpiece 12 to the feed conveyor 3 only when there is no workpiece over shoulder 9 and shoulder 10 with spring 11 raised.

In this position, the workpiece 12 is conveyed by the conveyor 2 up to the stop-guide 18 on the table 4, the shoulder 9 rises, and the shoulder 10 descends, the compartment 12, from the brush of the workpieces.

With the stop 16 of the chain 15, the workpiece 12 is fed to the machine. As soon as the workpiece 12 passes the arm 9, the latter is lowered, the lever 7 is rotated by the spring 11 relative to the hinge 8, the arm 10 rises and the cycle repeats.
