Description

[Detailed explanation of the idea] The present invention relates to a material feeding tool for wood cutting equipment.

Conventional wood cutting equipment conveys the movement of the material belt to the material using friction, so in order to obtain the necessary frictional force, the material belt must be strongly pressurized. Not only does the friction between the material and the material feeding table increase, which increases the power required for material feeding, but strong pressure on the material feeding belt can also cause the blade to sag, resulting in uneven cutting thickness or crushing of the blade. It deteriorates the cutting performance and durability of the blade, it also damages the material and causes scratches on the finished surface, making the cutting condition worse. Due to the large tension, even if they were made of expensive thick rubber, they would be damaged in a short period of time.

The present invention was devised in view of this drawback, and involves engaging the locking member of the main plate that frictionally engages with the material conveying belt with the friction piece to the end of the material, thereby transmitting the material feeding force to the material, The object of the present invention is to provide a material feeding tool that can reliably feed materials by applying light pressure on a material feeding belt.

Next, an embodiment of the material feeding tool for a wood cutting device according to the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a frame of a wood cutting device, on the upper side of which a material feeding table 2 is provided, and in the center of the material feeding table 2, a cutter 3 and a blade nozzle 4 are equipped.

Reference numeral 5 denotes a column erected on the frame 1 on one side of the table 2, which supports a head 6 which is raised and lowered by means of raising and lowering adjustment means (not shown in the drawings) such as a feed screw. The rollers 7 and 8 are mounted in a cantilevered manner,
A material feeding belt 9 corresponding to the material feeding table 2 is stretched, and a pressure member 10 such as a roller is engaged with the back side of the portion of the material feeding belt 9 corresponding to the material feeding table 2. A reversible electric motor 12 is linked via a speed reducer 11 to rotate the material conveying belt 9 in the material feeding or returning direction.

It should be noted that the head 6 is equipped with a cushion means (not shown in the drawings) such as a spring as is well known in the art for elevating and lowering adjusting means.

A is a material feeding tool, and a friction piece 14 made of the same effective material as the material feeding belt 9, that is, rubber, is attached to the upper surface of the main plate 13 made of metal, etc., and is in surface contact with the material feeding belt 9. As shown in Figure 2 of the drawing, the material 1 is made to protrude downward from both ends of the main plate 13.
A hook-shaped locking member 16 to be engaged with the edge of the material 15 is provided, and a contact piece 17 made of rubber or the like that hits the upper surface of the material 15 is attached between the locking members 16. As shown in FIG. 2 of the drawings, protrusions 19 made of wood, rubber, plastic, etc. are protruded below the locking member 16 at the front and rear ends, and if the material feeding tool A is not placed on the material 15, Even when the material is fed under the conveying belt 9, the protrusion 19 hits the cutter 3, and the locking member 1
This is to prevent the blade 6 from hitting the blade 3 and damaging the blade 3.

The friction piece 14, the contact piece 17, and the protrusion 19 in the material feeding tool A have grooves 20 in the vertical direction as shown in FIG. Even if a regular force is applied, each part can be expected to absorb this force and prevent it from spreading to the whole body. The head 24 or nut 25 of the mounting bolt 21 is housed in a recess 23 that is preformed on the surface side to match the hole 22 of the mounting bolt 21, and the head 24 or nut 25 of the bolt 21 is connected to the material conveying belt 9, material 15, This is to prevent the material from hitting the material feeding table 2 and damaging it.

One embodiment of the material feeding tool for a wood cutting device according to the present invention is constructed as described above, so that the material feeding tool A is
touches the upper surface of the material 15, and the rear locking member 16
The material conveying belt 9 is placed on the material 15 so as to engage with the rear end of the material 15.
When the material is fed downward, the friction piece 14 in the material feeding tool A is made of the same effective material as the material feeding belt 9 and comes into surface contact with the material feeding belt 9, so a small contact pressure produces a strong frictional force. The movement of the material feeding belt 9 is transmitted to the material feeding tool A, and the hook-shaped locking member 16 of the material feeding tool A is caught on the edge of the material 15, and the material feeding tool A is
In order to transmit the movement to the material 15, the material 15 can be reliably transported simply by applying slight pressure to the material conveying belt 9 and moving it in the material feeding direction.

The present invention consists of a main plate made of metal or the like, a friction piece made of a material with the same quality as the belt and fixed on the upper surface of the main plate and brought into surface contact with the material conveying belt.
Since the main plate is provided with a locking member that protrudes from the lower side of one or both ends and locks it to the end of the material, the movement of the material conveying belt is transmitted to the material by the locking member of the main plate, and the material is secured. Not only can the belt be fed reliably, but at this time, the main plate is in contact with the material conveying belt through a friction piece with the same effectiveness as the material conveying belt, and no slipping occurs. The material force is transmitted to the material without loss, reducing the friction between the material feeding table and the material, so the power required for material feeding can be greatly reduced, and the light pressure on the material feeding belt prevents the cutter from collapsing. As a result, uniform cutting with no unevenness in thickness is performed, and the blade does not collapse, resulting in better cutting performance and durability of the blade, and also prevents the material from collapsing and scratches on the finished surface. As a result, the cutting condition becomes good and the tension of the overlying material feeding belt is reduced, so that even if the material feeding belt is made of an inexpensive thin belt, it is economical and can be used for a long period of time.
