SU1212785A2 - Log feeding conveyer in front of machine - Google Patents

Description

I

The invention relates to lumbering, in particular, to the mechanisms for locating and feeding the logs to the milling units in front of the sawing frames when sawing logs to produce process chips, and is an improvement to the device according to the author. No. 1110631.

The aim of the invention is to increase the useful yield of sawn timber by increasing the accuracy of base stocking.

Not FIG. 1 shows the device, the view in FIG. 2 is the same, top view J in FIG. 3, section A-A in FIG. 1.

The device consists of a carriage 1 moving along the guides 2, the pneumatic machine 3, the pillar 4, the lower 11 directing to the cich knives 5 with t gami 6, the drive, for example, in the form of the pneumatic cylinder 7, the pressing knives 8, the pneumatic cylinder 9, inclined cylindrical 10 and exhaust rolls 11

The device works as follows.

 A log oriented on the frame carriages is fed to the front machine conveyor to form the outer layers of the beam. The carriage 1 by means of a pneumatic cylinder 3 is allotted to the extreme left position. When the top of the log is positioned between the lower guides, the knife 5 and the clamping knives 8, a command is given to bring them closer together, the log is clamped and fed between the inclined cylindrical heads

10, the formation of the outer layers of the beam with the receipt of technological chips. The knives 5 and 8 are pressed against the log with the same force using pneumatic cylinders 7 and 9 having the same parameters, which provides the necessary displacement clamped in the vertical plane without effort when relocating the curves of the logs in the vertical plane on the frame carriages. After fixing the top of the log with the upper rollers, 11 the guides 5 and the clamping 8 knives open, they return to the carriage 1 in the direction of the clamp 2 with the help of the pneumatic cylinder 3 to the initial position.

In this way, the basement of the log is provided in the initial period 20 of processing of the lumber plates with inclined cylindrical heads.

The inclined cylindrical heads 10 and suction rolls 11 are installed in the same vertical plane. They are set up relatively to the set, more precisely, the extreme saws in the set, using a ruler having a thickness equal to the thickness of the extreme side board, the rod is the width of the teeth to one side. The ruler is applied to the vertical suction rollers, which are brought to the back of the ruler contact with the extreme side saw.

In this way, the inclined cylindrical heads are adjusted for cutting out the required thickness of the side boards.
