JPS5816805Y2 - Saw-type automatic "tenon" removal device that prevents debris from being splashed by the saw - Google Patents

Description

[Detailed explanation of the invention] This invention is based on a handle saw that is attached to the elevating body by shifting it up and down.
The upper part of the lower part of the barrel saw is covered with plate removal, and the lowering of the lifting body allows the barrel saw and handle saw to cut into the material. When removing paulownia wood, the chips are removed from the lower saw. If the debris falls to the side, the back side of the saw is guided downward by plating to prevent it from falling onto the saw below, preventing the saw from splashing debris, and protecting the safety of the operator and the saw and machine. The present invention relates to a device for preventing debris splashing caused by a saw in a saw-type automatic offset board, and an embodiment thereof will be described below with reference to the drawings.

In the figure, 1 is a machine base, and a vertical guide 2 is erected at the rear of the machine base.

3 is an elevating body supported by the vertical guide 2;
A conveying mechanism 7, such as a chain wire, is attached to chain wheels 4.5 disposed above and below the center of the chain wheel 4, and is rotated in the vertical direction by a reversible motor 6 linked to the chain wheel 4, within a predetermined range. It is designed to be raised and lowered.

A wire 8 is tied to this elevating body 3, and the wire 8 is suspended from the upper part of the guide 2, bypassing a pulley 9 that is a pivot support, and hanging downward from the rear side. A balanced weight (not shown) is suspended so that the elevating body 3 can be moved up and down easily.

Reference numeral 10 denotes a horizontal guide provided at the front of the elevating body 3, which supports a pair of left and right carriages 11.11.
The adjustment members 12 are linked to adjust the corresponding spacing symmetrically by means of right and left side panels (not shown).

Reference numerals 13 and 13 designate a pair of barreled saws that are attached to the lower side (sometimes the upper side) of the carriage 11;

15. Reference numeral 15 denotes a pair of paulownia saws attached to the upper side (or lower side in some cases) of the carriage 11.11 facing forward and backward, and rotated by motors 16,16.

17. 17 is a cover for the saw with a barrel 13°13, and the saw with a barrel 13
．． The outer half of 13 was covered.

18.18 is the plate removal of chips, and the lower edge is cut with a barrel saw 13.1
The upper peripheral surface of 3 is dyed with 1911, and the removing plates 18, 18 are attached to the cover 17.17 and provided above the saw 13.13 so as to coincide with the saw 13. 1
5 and 15 close to the outer surface.

Reference numeral 19 denotes a material holder provided on the machine base 1 on the front side of the elevating body 3, which is shaped like a vise and has a paulownia forming part for holding the material. 15, 15, and when forming a long paulownia tree, this holder 19 is guided by a horizontal guide 20 so that it can be drawn out.

Reference numeral 21 denotes a chip transport conveyor provided at a chip drop position on the machine base 1, which is driven using the lifting power of the elevating body 3 to sequentially transport the fallen chips to the outside.

Reference numeral 22 denotes a safety cover that shields the body saw 13. The machining section is supported by the locking piece 24 of the lifting body 3 and moves along with the lifting body 3, but when the lower end hits the material, it rests on the material and stops. .

In addition, in this device, when the saws 15, 15 are located below, the cutting board 18 for removing chips is provided above the saws 15, 15 in accordance with the above. The accompanying drawings and explanations are omitted.

Conventionally, a vertical guide supports an elevating body that is raised and lowered by a feeding mechanism, and a pair of saws with a body and a paulownia saw are attached to this elevating body in a vertically shifted manner. There was a saw-type automatic retrieval machine that removed paulownia wood by cutting into the material supported by a holder below it when the elevating member was lowered. To cut the sheath with a saw,
Block-shaped chips placed on the lower side of the paulownia wood may fall down, chipping the teeth of the saw, being thrown off by the rotation of the saw and colliding with the machine, or flying outside and causing damage to people and property. This had the disadvantage of causing damage to machinery and property, as well as personal injury.

However, when the apparatus according to the present invention arranges the saws 15, 15 on the upper side and the saw with a barrel 13.13 on the lower side, as shown in the above embodiment, , removal of chips 18.1 with the lower edge adapted to the upper circumferential surface of the saw 13.13
8 is vertically installed above the saw 13.13 so that the inner edge approaches the outer surface of the saw saw 15.15. , 15, even if block-shaped chips are cut off from both sides of the handle a, these chips can be removed by the cutting board 18, which is vertically installed on the body saw 13 and 13 in line with the above. , 18, the barreled saw 13.
13 is guided downward, and is dropped onto the carry-out conveyor 21 without falling onto the barreled saw 13.13.
This has the great effect of preventing chips from being thrown away by the barreled saw 13, 13, and completely eliminating damage to machines and equipment and accidents resulting in injury or death.

[Brief explanation of the drawing]

The drawing shows one embodiment of the device according to the present invention.
The figure is a partially cutaway front view of an automatic delivery board that uses this device. FIG. 2 is a perspective view showing the structure of the device. In the figure, 2 is a vertical guide, 3 is an elevating body, 7 is a feed mechanism, 13.13 is a saw with a barrel, 15.15 is a sawing saw, 19 is a material holder, and 18 is a chip removal plate. .
