あった。Recently, the rear end of the conveyor frame has been pivoted to the upper part of the machine frame, and the conveyor frame has been made to be raised and lowered from the horizontal position by a lifting mechanism.The front part of the conveyor frame is supported by a movable frame that is pressed forward by a spring. Conveyor rollers are pivotally supported at the front end of the frame and the pivot joint of the conveyor frame, and a slack belt is passed around the second conveyor roller. A lever facing the bottom of the movable frame is pivoted, a receiver is provided at the pivot point that touches the outer surface of the belt, a tension wheel is provided at the front to hold down the inner surface of the belt, and a lever is attached to the machine frame at the rear of the lever. A cam corresponding to a shaft-mounted roller is connected in series, and when the conveyor frame is horizontal, the top of the cam touches the roller, and as the conveyor frame tilts upward or downward, the point of contact with the roller moves to the bottom. Formed in a chevron shape, the belt is loosened as the conveyor frame rises and falls, and the movable frame is advanced and retreated to raise and lower the front conveyor roller straight, so that the stacking of boards, etc. on the tatami floor is not bent. A presetting machine for woodworking machines was developed that allows the machine to perform straight work, but this machine uses a cam to operate the tensioning wheel.
The movable frame was moved forward and backward by tensioning and loosening the belt, and the front conveyor roller was moved up and down in a straight line. This creates a difference in the amount of movement, deflects the tip of the conveyor to the left and right, and causes fluctuations in the feeding direction, making it impossible to feed and stack materials correctly in a fixed position, and reducing the operating force from the belt to the movable frame. This has the disadvantage that uneven overload acts on the belt and accelerates belt wear, and it also prevents distortion and deformation of all parts such as the machine frame, conveyor frame, levers, cams, etc. If the conveyor is not made to be strong and strong, smooth adjustment of expansion and contraction of the conveyor cannot be expected, which not only increases the production cost of the machine but also increases the weight of the machine, which also has the disadvantage that it is not easy to connect and deploy related equipment when moving the machine. Ta.

軽微で耐用年数以上の安全使用が出来るものである。However, the front removal machine for a woodworking machine according to the present invention has its rear end pivoted to the upper part of the machine frame, and the front part of the conveyor frame, which can freely swing up and down from a horizontal position, is moved forward and backward. A movable frame is freely supported, a conveyor roller is pivotally supported at the front end of the movable frame, and an adjustment roller is pivotally supported at the rear end, and a conveyor roller is pivotally supported at the rear end of the conveyor frame, and a receiving roller is pivotally supported at the lower front end. Then, a belt is passed through each of the above-mentioned ports, and the length of this belt can be adjusted by advancing and retracting the above-mentioned movable frame.At the bottom of the belt conveyor, an operating rod that is longer than the conveyor frame is attached so that its upper end is adjustable. It is pivotally connected to the shaft of the front conveyor roller, and its lower end is arranged so as to roll on a horizontal guide surface at the bottom of the machine frame, and its midpoint is located at the center of the half of the operating rod, which has a fulcrum at the front end of the horizontal guide surface. The belt is pivoted to a length lever, and this lever moves the operating rod up and down, allowing the front conveyor roller to move vertically up and down. Even if there is a movable rod driven by the operating rod, the left and right sides operate equally without being affected by tension differences, and the belt is stretched straight without causing any deflection of the tip, so the direction of article feed is always constant. , which ensures the correct delivery and stacking of articles to a fixed position, and since only the load of the conveyed articles acts on the belt conveyor, wear and tear on the belt is minimal and it can be used safely for longer than its service life. It is.

ることもないものである。One embodiment of the advance picker for a woodworking machine according to the present invention is configured as described above, so that after aligning the rear end of the relay belt conveyor 24 with the delivery position of the material 26 on the woodworking machine 25, When stacking materials in two rows, front and back, the rear half of the truck 4 is inserted between the guide surfaces 2 and 20, and with the front end of the belt conveyor 15 facing the center of the truck 4, the motor 31 If the belt conveyors 15 and 24 are rotated,
The material 26 sent out from the woodworking machine 25 is transferred to the conveyor 24.
15 to the front half of the truck 4, and along with this, the detector 3
5 detects the material 26, sends a rising signal to the elevating mechanism A, and when the elevating mechanism A raises the conveyor 15 by the thickness of the material 26 and stops, the next material 26 is sent and the conveyor 15 is moved in advance. The operator repeatedly steps on the material 26 and activates the detector 35 to raise the conveyor 15, thereby automatically stacking the material 26 onto the cart 4. In this case, the front conveyor roller of the conveyor 15 The shaft 12 of 11 is an operating rod 2 whose lower end is in contact with the horizontal guide surface 2 and whose middle portion is pivoted to a lever 23 having a fulcrum 22 at the front end of the horizontal guide surface 2.
The operating rod 20 is pivoted about the fulcrum 22 of the lever 23 to give it forward and backward movement as it moves up and down, so that its upper end is always vertical as shown in the principle diagram in Figure 4 of the drawing. Since the front conveyor roller 11 moves up and down along the lines B and C, the front conveyor roller 11 moves backward as it rises until it reaches the horizontal position, pushing in the movable frame 10, and adjusting the amount of belt feeding by the adjustment roller 13. is gradually increased to shorten the length of the conveyor 15, but above the horizontal position, it moves forward as it rises, pulls out the movable frame 10, reduces the amount of belt feeding by the adjustment roller 13, and reduces the length of the conveyor 15. Stretch out,
If this operation is not performed, the conveyor 1 moves up and down along an arcuate trajectory centered on the axis 8 of the rear conveyor roller 7.
Not only is it possible to perform accurate automatic stacking without causing any disturbance or bending of the materials by giving vertical movement to the tip of 5, but also by driving the movable frame with the operating rod.
Since the left and right sides of the conveyor are synchronously and evenly expanded and contracted, the tip of the conveyor does not deflect due to expansion and contraction, thereby preventing changes in the feeding direction.
