The chain type feeding mechanism 2 with the feeding guide ruler 1 is arranged between the first workbench B and the second workbench C and used for transversely moving a first workpiece 3 and a second workpiece 4 processed in the first tenoning machine according to a main conveying direction 5 until a second end of the processed workpiece D reaches a preset position required by processing operation of the second tenoning machine 6. The chain type feeding mechanism 2 is provided with a plurality of processing workpieces D, and the first workpiece 3 and the second workpiece 4 both belong to the processing workpieces D.
In particular, prismatic workpieces one 3, two 4 made of wood of unequal length are conveyed by the chain feeder 2 transversely to its longitudinal axis through a not shown tenoner arranged offset longitudinally on both sides of the intermediate chain feeder 2, the feed guide bar push surfaces 1.1 of the chain feeders acting at a main conveying speed in a main conveying direction 5 on their upstream workpiece-side surfaces 3a, workpiece-side surfaces 4 a.
In the pushing process of the chain type feeding mechanism 2, the pushing surface 1.1 of the feeding guide ruler pushes one end part 3b and the two end parts 4b of the unprocessed workpiece, and the first workpiece 3 and the second workpiece 4 are continuously pushed transversely along the crossed path under the cooperation of the transverse pushing belt 7 until the one end part 3b and the two end parts 4b of the workpieces reach the preset position of the processing operation of the second tenoner 6. Further downstream, they reach the transverse positioning guides 8, on which transverse positioning guides 8 their end faces are aligned for subsequent machining operations.
Wherein the transverse push belt 7 surrounds the drive wheel 10 and the guide wheel 11 at an angle 9 to the main conveying direction 5 and is supported vertically on the surface of a support 12 arranged between the drive wheel 10 and the guide wheel 11, the workpiece is pressed under the pressing device 13, and in the main conveying direction 5 of the working area of the guide wheel 11 at least one pressure roller three 14 is supported by force from above in a rolling manner on the workpiece, the rolling direction of which is indicated by an arrow 14a, is inclined in a rolling manner at an angle of attack 15 relative to the main conveying direction 5, so that the workpiece leaves the working area of the guide wheel 11 of the transverse push belt 7 before being lifted to an impermissible extent from the feed guide push surface 1.1 of the chain feeder 2.
In the lateral pushing area, the workpieces one 3, two 4 arranged on the chain feeder 2 are acted upon by an upper pressure device 13 (in the case shown, a spring-loaded pressure lip 13 a) and are supported in a controlled frictional manner on the chain feeder 2 and its feed guide bar push surface 1.1.
In the main conveying direction 5 in the region of the transverse pushing path, at least one pressure roller four 16 is supported on the workpiece in a rolling manner from above under the action of force, and the rolling direction indicated by an arrow 16a is inclined relative to the main conveying direction by an angle of attack 17> angle 9, so that the workpiece is pushed more smoothly under the action of the pressure roller four 16.
As shown in fig. 1, 2, 3 and 4, the workpiece 4 leaves the transverse pushing belt 7 at the point marked X at the angle of attack 15 by the action of the third pressure roller 14 and is fed crosswise until it reaches the second, oppositely positioned pressure roller 18, the second pressure roller 18 being arranged on the second roller frame 19, and then the transverse positioning guide 8 is aligned by the action of the second pressure roller 18 and of the other similarly positioned pressure rollers (the first pressure roller 20, suspended individually or in pairs, the first pressure roller 20 being arranged on the same first roller frame 21). Pressure roller three 14 and pressure roller two 18 are disposed on a common spring-loaded roller stand two 19, a lower surface portion 18b of pressure roller two 18 being lower than a corresponding lower surface portion 14b of pressure roller three 14 supported on the workpiece.
