JPS5914173Y2 - Core log removal device in rotary race - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for removing core logs removed from the chuck after stripping of the rotary race from outside the rotary race.

Conventionally, the lower race base (cradle) of the log, which is firmly held in the rotary race chuck, has a flat surface, so when the stripping is finished, the core log removed from the chuck is placed on the race base, so the work is done. It had been manually removed from the rotary race.

In addition, the core logs may break or break during stripping, resulting in wood chips.

Wood chips, broken core logs, etc. also accumulated on the lace base, so workers had to remove them by hand.

As a result, the rotary race cannot be operated while the worker removes the core logs and debris, resulting in extremely low work efficiency.

In addition, to improve work efficiency, workers can use core logs while working.
This method had some problems, such as requiring dangerous actions to remove debris.

In order to solve these problems, the surface of the lower race base of the log that is firmly held in the chuck of the rotary race is made into a sloped surface, or a cradle with a sloped surface is installed on the race base so that it can be removed from the chuck after the log is peeled off. The removed core log was removed from the rotary race by rolling it down the slope.

However, in this direction, if the core log is in a normal state (cylindrical shape), it will roll out, but wood chips or broken core logs that are splintered or split during stripping cannot roll out. The rotary race remains on the slope, and as shown above, the worker must remove it by hand, which does not allow the rotary race to operate at full capacity, reducing work efficiency and creating a dangerous situation. There are some problems, such as the work involved.

This invention removes the core log (including wood chips or broken core logs caused by chips or cracks) removed from the chuck after stripping is completed and removed from the rotary race without the operator's intervention. The purpose is to run the system at full capacity and improve work efficiency.

The structure of the present invention is that a conveyor 9 is disposed in front of the rotary race 1, and one end of the conveyor 9 is attached to the lower part of the tool rest 4 below the log that is firmly supported by the chuck 3 of the rotary race 1, and an arbitrary inclined surface is formed. This device relates to a core log removing device for a rotary race in which a skirt 7 with a base 7 is disposed so that its tip is in contact with the surface of a race base 8, and the skirt 7 moves in the same direction as the tool post 4 moves.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A description will be given below based on embodiments of the present invention shown in the drawings.

1 is a rotary race and 2 is a conveying device (not shown)
The spindle 2 firmly holds the log transported by the
3 is a chuck disposed at the tip of the spindle 2.

The raw wood transported by the transport device is firmly held by the chuck 3 at the tip of the spindle 2 so that its center coincides with the axis of the spindle 2.

The held raw wood is rotated and cut into a veneer of constant thickness by the action of the knife attached to the tool rest 4 and the pressure bar of the saw stand 5.

The tool rest 4 and the saw rest 5 are integrally constructed, and are moved horizontally on a slide 6 by a drive device (not shown) while being guided by a guide plate 10.

The turret 4 and the saw holder 5 move horizontally toward the spindle 2 to cut a band-shaped veneer.The rotary race 1 cuts a strip of veneer. A skirt 7 having a surface is arranged so that its tip is in contact with the surface of a lace base 8.

Since one end of the skirt 7 is attached to the tool rest 4, it moves horizontally in the same direction as the tool rest 4 moves horizontally.

The raw wood is cut into a band-shaped veneer by horizontal movement of the tool rest 4 and the saw stand 5 toward the spindle 2, and at this time, wood chips due to cracks and the like fall onto the race base 8.

The fallen wood chips are gradually pushed by a skirt 7 attached to the turret 4 toward a conveyor 9 disposed in front of the rotary race 1.

After being removed from the chuck 3, the core log 11 that has been stripped falls onto the lace base 8 or the skirt 7, and at the same time is conveyed by the skirt 7 to the conveyor 9 together with the previously mentioned wood chips.

As described above, the present invention utilizes the movement of the tool rest 4 during cutting by attaching the skirt 7 such that one end is fixed to the tool rest 4 and the other end is in contact with the race base 8. Wood chips fallen on base 8, core log 1
1 to the outside of the rotary race 1, there is no need to install any driving device, there is no need for wood chips or core logs to accumulate on the race base 8, and the rotary race 1 can be operated at full capacity.

Therefore, productivity is improved and the work can be performed safely without requiring any workers other than the rotary race operator.
