Description

The invention relates to the woodworking industry, in particular to furniture manufacturing equipment.

The purpose of the invention is to increase productivity and reliability.

FIG. 1 shows a diagram of a device for trimming a rear overhang on a edge facing machine; in fig. 2 is a view A of FIG. 1; . .f; ig.3 - view B in FIG. 1. The device for trimming the rear overhang on the crushing machine contains a stand I, a sawing unit, -2 mounted on the bed 1 using parallel levers 3 parallel to it, and a mechanism 4 for moving the sawing unit. On the rack 5 of the platform 6 of the saw unit 2 with the aid of an axis 7 is fixed, made in the form of a dog, an emphasis 8 with a spring 9 holding the movable end of the emphasis 8 in the initial position. The stop is located higher than the axis of rotation of the saw unit. The movement mechanism 4 of the sawing unit includes the assembly unit 10 for setting the sawing unit to the operating position, a spring 11 attached at one end to the frame 1, the other to one of the arms 3 parallelly arranged, and a stop 12 securing the arms 3 parallelly located in the initial position.

The movement mechanism of the sawing unit is made in the form of a horizontal shaft 13 mounted in bearings 14 attached to the frame 1 from below. At one end of the shaft 13, a stop lever 15 is rigidly mounted, at the other end there is a drive gear wheel 16, in engagement with which there is a driven gear wheel 17 of a vertical shaft 18 mounted in bearings (not shown) of the bed 1. At the other end of the vertical shaft 18 One of the parallel levers 3 are rigidly mounted, the other lever is attached to the frame 1 by means of an axis 19. The part 20 is processed on the device.

The device works as follows. Moving in the zone of the rear overhang removal, the workpiece 20, with its front end, rotates the thrust lever 15 of the sawing unit assembly 10 at a certain angle into the working position, and with it the shaft 13 installed in the bearings 14 with the driving gear 16 and then, through engagement, the driven gear 17, the vertical shaft 18 and the lever 3 parallel to it, thereby causing the sawing unit 2 to retract into the working position and at the same time stretch the spring 11. In this case, the movable end of the stop 8 is pressed the front end and the top plane of the workpiece 20 upwards, where it is held for the time it passes. When the workpiece 20 leaves the rear overhang area, the movable end of the stop 8 first releases, which, under the action of elastic forces of the spring 9, returns to its original position, and then the stop lever 15. When the stop lever 15 is released, the spring force of the spring I, through one of the parallel to the levers 3 on the node 10 installation of the saw unit in the operating position, takes with it the saw unit 2 to its original position. Moving to the limiter 12, the saw unit 2 cuts the overhang on the rear end surface of the workpiece 20, based on the specified surface using the stop 9.

When the next workpiece enters the trimming area of the rear overhang, the cycle repeats. The use of the proposed device for trimming the rear overhang on the edge banding machine improves the operating conditions of the device, increases its reliability and increases productivity by up to 15% by reducing the time interval between the feeds of parts on the edge banding machine.
