Description

[Detailed Description of the Invention] This invention relates to a device for removing defective products produced when a plate-shaped wood is divided into a required number of pieces.

Conventionally, when a plate-shaped piece of wood is cut into pieces using rotary saw blades arranged in parallel at intervals corresponding to the cutting width, defective products are produced on both sides.

By sending this out as is, there was a problem that defective products were mixed into the product.

For this reason, it is necessary to manually remove the defective products, and if the product is thick, long, and heavy, many people have to take out the defective products. Ta.

The purpose of this invention is to provide a device in which defective products produced during cutting are taken out outwardly by a movable claw.

Embodiments of this invention will be described below with reference to the accompanying drawings.

In the figure, A is a cutting machine that cuts each plate-shaped wood a into the required width, and this cutting machine A has a first conveyance path 1 for the wood a,
A dividing cutting device 4 is provided in front of the first conveyance path 1, which is composed of a drive shaft 2 that crosses the first conveyance path 1, and a saw blade 3 arranged in a set number of sheets in parallel on the drive shaft 2 at a predetermined interval. and a second conveyance path 5 consisting of a roller conveyor for discharging the divided wood.

In the middle of the second conveyance path 5, a seat member 6 is provided which moves up and down.

Further, two rotating shafts 8 and 9 whose axes are horizontal and sandwich the second conveyance path 2 are supported via an arm 7 connected from the seat material 6, and the rotation shaft 8 is supported between the rollers of the second conveyance path 2. . Hand over, above Cheno 12, 13
The claws 14 and 15 that bite into the space between the cut pieces of wood are fixed.

Furthermore, the pawl 14 that is stopped on the upper forward side of the chino 12 is moved to the left in FIG. 3, and the pawl 15 that is stopped on the upper forward side of the chino 13 is moved to the right in FIG. Let it run.

In addition, a required number of hand switches 16 from 1 to 1 are provided in parallel in the width direction in front of the first conveyance path 1, and a chino 12,
A limit switch 17 is arranged in parallel under the forward side of the handle 13 at an interval equal to the width of the cut wood and is in contact with the claw 14. A limit switch 17 located at the same position as the switch 16 operates, and the claw 14.1 is attached to this limit switch 17.
5, the operation of the drive mechanism 18 of the rotating shafts 8, 9 is stopped so that the pawls 14, 15 are stopped.

Incidentally, the seat 6 is moved up and down by a cylinder 20 that supports the end of the frame 19 and a piston shaft 21 whose tip is fixed to the lower surface of the seat 6.

Further, a roller conveyor is also used in the first conveyance path 1.

In addition, instead of using the chino described above, it is also possible to attach a pawl to the piston of the cylinder and slide the pawl.

The use of the take-out device according to this invention will be explained based on the above-mentioned configuration. Before cutting the plate-shaped wood a, the seat material 6 is lowered by retracting the piston shaft 21.

Next, by feeding the plate-shaped wood a into the cutting device 4 with the leading end of the plate-shaped wood a facing above the base end of the first conveyance path 1, the plate-shaped wood a is divided by each saw blade 3. Can be cut.

At this time, defective products a ” are produced on both sides of the divided wood a′.
By operating the hand switch 16 that corresponds to the hand switch 16, the limit switch 17 at the same position as the hand switch 16 comes to work.

Therefore, when the pawls 14.15 of the traveling chenos 12, 13 come into contact with the limit switch 17, the pawls 14.15 are stopped at this position.

When the split wood a' is discharged to the second conveyance path 5 and stopped, the seat material 6 rises.

At this time, the claws 14 and 15 are respectively injected between the defective product a'' on both sides and the split wood a' on the inside, and then the claws 14 and 15 are inserted on the opposing outer side (claw 14. 1
It travels to the defective product a'' side which is in contact with 5.

Therefore, the defective product a'' is taken out from the second conveyance path 5.

Each divided timber a' is sent out by the next divided timber a', and the seat material 6 is lowered.

As described above, according to the device for removing defective products according to the present invention, the plate-shaped wood is divided by each saw blade of the cutting device, and the defective products on both sides of the divided wood sent to the second conveyance path are removed. , since it is adapted to be taken out laterally after being locked with the pawl rising on the second conveyance path, it has the excellent effect of being able to be taken out automatically, unlike the conventional manual taking out.

In addition, automatic removal using a claw improves operating efficiency.
