摘要： PROBLEM TO BE SOLVED: To make a position-adjusting operation of a positioning member easy in a work timber positioning device for a woodworking machine equipped with the positioning member for positioning the work timber with respect to a working edge. SOLUTION: A ruler-adjusting arm 31 is fixed or released from fixation by pushing against or separating a setscrew 83 of a locking mechanism 8 from a projected part 51 by moving it on or back by carrying out a pivotal operation in a vertical direction of an operating lever 7 in a planer. Further, a ruler adjusting arm 31 is allowed to horizontally pivot by using a pin 33 as a fulcrum by carrying out horizontally pivotal operation of the operating lever 7 in a fixation-released state. The ruler 3 is moved in front or in rear and positional control of the ruler 3 to the planer is carried out thereby.

摘要： PROBLEM TO BE SOLVED: To raise a precision for a positional display by ensuring an action of an indicator in order to solve the problems that the action of the indicator is instable and its positional display precision is bad since a display for a position of a cutting edge for confirming the position of the cutting edge arranged at a rear surface side of a table from a front surface side of the table is conventionally so constituted as to interlock the indicator to movement of the cutting edge by using a pulley and a cord. SOLUTION: The indicator 70 for displaying the position of the cutting edge 12 is arranged at the front surface side of the table 2. The indicator 70 is coupled to a reversal side of a chain for transferring a cutter main body via a functioning wire 71 and the indicator 70 is moved by the same distance in the same direction as those of the cutter main body.

摘要： PROBLEM TO BE SOLVED: To properly set the pressing force which is maintained by a following-up type fixed pressing function. SOLUTION: When a head comes into contact with a charged material to be cut, a supporting nut 11 is screwed upward by the rotation of a screw shaft 8, and a dog 17 stops at a position where an LS 1 is turned on (an LS 2 is off). At this time, a load to the material to be cut, which is obtained by the compression of a coil spring 12, is maintained as a fixed pressing. In the meantime, when a slide plate 27 to which the LS 1 is attached is vertically slid, an adjustment of the fixed pressing becomes possible, but a coil spring 13 is arranged under the supporting nut 11, and the weights of the head and a frame are loaded, and the fixed pressing can be selected in a total area which is not more than the weights of the head, etc., and also, in a range of normal usage.

摘要： PROBLEM TO BE SOLVED: To enhance operability of a positioning apparatus by providing a cutting apparatus equipped with the positioning apparatus capable of adjusting an operating position, in a horizontal type panel saw (a cutting apparatus) wherein a table for setting a cutting object matter is horizontally arranged, the positioning apparatus of the cutting object matter is provided on an opposite side to an operation position, then conventionally an operator has to move to the opposite side of the table to executes its adjusting operation. SOLUTION: A positioning apparatus 101 is equipped with a positioning stopper 133 for controlling a position in a direction crossing at right angles a cutting direction of a cutting material W by allowing the cutting material W to abut thereagainst, and a position of the positioning stopper 133 is enabled to be adjusted by rotary operation of a handle 120 provided on a cutting operating position side of a table 111. Rotation of the handle 120 is transmitted to screw shafts 126 and 126 via a support 121 and a chain transmission mechanism, and block bodies 130 and 130 are transferred thereby.

摘要： PROBLEM TO BE SOLVED: To improve the operability of a material thickness detecting device for automatic wood planing machine, by making the initialization of a photoelectric sensor easier. SOLUTION: A material thickness detecting device 13 is constituted of a gate 15, and a photoelectric sensor composed of a first light emitting device 16 and a second light receiving device 17 positioned to one end section 15a of the gate 15, and a second light emitting device 18 and a second light receiving device 19 positioned to the other end section 15a of the gate 15. The gate 15 is attached to a bridge 14 so that the lower surface of the gate 15 may be set at the highest cutting height. The light emitting and receiving devices are positioned in parallel with each other, so that the light beam L1 between the first light emitting and receiving devices 16 and 17 may be separated slightly from the lower surface of the gate 15, and the light beam L2 between the second light emitting and receiving devices 18 and 19 may be separated form the light beam L1 by the maximum cutting amount. In addition, the head sections 25 and 25 of adjusting screws 24 and 24 which are screwed in the lower surface section of the bridge 14 are inserted into the rear surface section of the gate 15, so that the height of the gate 15 may be changed when the screw 24 and 24 are turned while the gate 15 is temporarily fixed.

摘要： PROBLEM TO BE SOLVED: To adjust the wood transfer interval quickly and accurately. SOLUTION: When either one of a lifting button 13 or a lowering button 14 is ON-operated once by utilizing an inverter, the acceleration driving and the inching control for controlling a brake can be carried out by a reversible motor 7 so that a head 3 can be lifted and lowered by the minimum unit of 0.1 mm by a controller built in an operation panel 11. Also the number of rotations of a driving shaft 8 sensed by a rotary cutter 10 is fed back to the controller to correct the control error. Therefore, the head 3 is lifted by 0.5 mm by repeating five times the operation of the lifting button 13 in a mm display when the lifting distance to a target value is set as 0.5 mm.
