Description

[Detailed Description of the Invention] The present invention relates to a two-sided sawing material feeding device used in a sawmill.

Conventionally, the material feeding device used in double-side sawing machines such as twin band saws has been a trolley-type device in which a rail is passed between a pair of saws and a trolley moves forward and backward along this rail.
In the case of small-diameter wood such as thinned wood, there was a drawback that the cart became unstable and the wood could not be sawn accurately.

This invention was devised to eliminate this drawback.
To provide a material feeding device for two-sided sawing, in which a running board having a wood grip is sandwiched between sliding boards, and the material can be sawn stably and accurately even in the case of small-diameter wood.

Next, an example of the implementation of the device related to the present invention will be explained based on the drawings.

1 and 2 of the drawings, reference numerals 1 and 1 denote a pair of frames in a twin band saw A, on which an idling saw wheel 2 and a driving saw wheel 4 rotated by a motor 3 are pivotally supported,
A band saw 5 is attached to each of the saw wheels 2 and 4, and the frames 1 and 1 are rotated in conjunction with a deceleration motor 6, and the frames 1 and 1 are rotated in opposite directions by left-handed and right-handed screws. This is done by engaging the walking means 7 for moving.

B is the left and right band saws 5, 5 in the Twin Pantone-A.
A material feeding member for feeding material between the running plates 8 and 8 has a fixed wooden grip 9 at one end and a movable wooden grip 11 moved forward and backward by a cylinder 10 at the other end.

Reference numeral 12.12 denotes a support plate for the running plate 8, which is erected on the platform 13 at a predetermined interval, and inside thereof there are sliding plates 14, 14 made of synthetic resin such as Duracon, which has a low coefficient of friction and high wear resistance. are arranged, and the contact plates 15, 15 provided on the outside thereof are held down by hollow push screws 16.16 screwed into the support plate 12.12, and nuts 17 are placed on the inside of the slide plates 14, 14.
, 17 is inserted, and this nut 17.17 is pulled by the drawing screws 18, 18 screwed into the hollow push screws 16, 16, and the running plate 8 is made light without rattling by the sliding plate 14.14. Please support us as we advance and retreat.

Reference numeral 19 denotes a means for advancing and retracting the running board 8, which uses a check 7 that is stretched parallel to the running board 8 in the platform 13, fixed at one point to one end of the running board 8, and rotated forward and backward by a motor 20.

Reference numerals 21 and 21 denote circular saw holders attached to the front parts of the frames 1 and 1 of the twin band saw A described above, and horizontal guides 23 and 23 in which motor stands 22 and 22 are movably engaged are provided on the upper part of the holders. It is.

24. 24 is a motor attached to the above-mentioned motor stand 22.degree. 22, and a circular saw 26.degree.

Reference numeral 27.27 is a walking means such as a feed screw for moving the motor stand 22.22, which is rotated by the reduction gear motors 28, 2B to adjust the distance between the band saw 5 and the circular saw 26.

29. Reference numeral 29 is a tensioning means of the band saw 5.5 in the above-mentioned twin band saw A, and the weight of the weight 30 is transmitted to the lifting means 33 of the spall 32 by a balance 31 to apply an appropriate tension to the band saw 5.

34. 34 is a saw, sandwiching the band saws 5, 5 described above,
Suppress that vibration.

35. 35 is the frame 1, 1 with the running board 8 mentioned above in between.
It is rotated in the direction of material feeding by a conveyor for discharging offcuts provided above.

Reference numeral 36.36 denotes a side discharge plate for offcuts provided at the rear with respect to the material feeding direction of the carry-out conveyor 35.35, and is inclined laterally.

Reference numeral 37.37 denotes a plate carrying-out means for carrying out the plate that falls between the advance/retreat path 38 of the running plate 8 and the discharge plate 36.36.

In the device constructed as described above, the support plate 12.12
A sliding plate 14.14 with a contact plate 15 is placed on the inside of the plate.This sliding plate 14.14 is held down by hollow set screws 16, 16 screwed to the supporting plate 12.12, and a nut 17 is embedded inside. .17 is pulled and positioned by the draw screw 18.18 screwed into the hollow push screws 16, 16, the running plate 8 is inserted between them, and the push screw 16.16 and the draw screw 1B, 18 By relatively adjusting these, the running plate 8 is parallel to the bandsaws 5, 5 and 26, 26 without any wobbling, and
It is supported by sliding plates 14°14 so that it moves forward and backward with ease.

Therefore, the wooden grips 9 and 1 provided at both the front and rear ends of the running board 8
1, for example, if thinned wood is gripped and the running plate 8 is advanced toward the saws 5, 5 and 26° 26 by the advance/retreat means 19, the material is first cut into scraps from both sides by the circular saws 26 and 26. is sawn off, and then sawn into the main product for corners in the center and the sub-products for plates on both sides by band saws 5, 5, completing the main and sub-product removal and scrap removal at the same time. However, during this sawing, the running plate 8 held between the pair of sliding plates 14, 14 maintains a completely parallel state with the saws 5, 5 and 26, 26, is stable, and does not tilt against the cutting load. The resulting product is accurate and has a good grinding surface because it does not generate vibrations or vibrations.

The device related to the present invention adjusts a hollow push screw screwed into the support plate and a draw screw whose tip is threaded through the hollow push screw and screwed into the embedded nut of the sliding plate, so that the sliding plate can be attached to both sides of the running plate. If it is fixed in the pressed state, the running plate with wood grips can be supported by the pair of sliding plates so that it moves easily and advances easily without wobbling, so that the material feeding by the running plate is not affected by the cutting load. This device performs stably without tilting or vibration, and even when two-sided sawing is used to cut small angles or boards from thinned wood or other small-diameter wood, it is possible to obtain extremely accurate and fine-grained products. Because it has a simple structure in which the running plate is sandwiched between a pair of sliding plates, it can be implemented at low cost, and when the sliding plate wears out, it can be easily corrected by adjusting the screw, maintaining initial accuracy for a long time. This has the unique effect of making it possible to
