Description

Description: [Industrial field of application] The present invention relates to an automatic wood marking device, and more particularly to a wood marking device that can quickly and reliably carry out wood marking prior to wood processing. The present invention relates to the automatic blacking device.

[Conventional technology]

The timber that constitutes a wooden building can be roughly divided into pillars and horizontal members that are horizontally fixed between the pillars.

Since each horizontal crossing material has a different processing shape, it takes a lot of time for so-called blacking, which is performed on the wood before processing so that the wood is processed according to the processing shape. .
Moreover, since the blacking operation requires a great deal of skill, automation of the blacking operation to be performed on wood has been strongly desired these days due to lack of manpower.

[Problems to be Solved by the Invention]

However, there has not yet been proposed an apparatus that can perform the blacking operation with good yield in a short time.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an automatic wood sanitizing device capable of reliably sanitizing wood prior to processing the wood with good yield and in a short time.

[Means for Solving the Problems]

The present invention is a shape measuring means for measuring the width, height and length of the loaded wood, respectively, and digging the wood,
Prior to performing processing such as drilling, it comprises an inking machine for inking wood and a controller, and the controller stores shape measurement data from the shape measuring means and is stored in advance. Various product wood Compared with the product shape data of wood, which consists of width, height and length, it is judged whether or not it is possible to perform processing such as grooving and drilling, and processing If possible, from the pre-stored product shape data, select the wood product shape that can be processed with the highest yield, and select the product shape thus selected for the wood shape. So as to be processed, it is characterized in that it has a function of issuing a sanitizing instruction for sanitizing wood.

Next, one embodiment of the automatic wood marking device of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view showing an embodiment of an automatic wood marking device of the present invention, FIG. 2 is a sectional view taken along the line AA of FIG. 1, and FIG. It is a front view which shows a state.

As shown in FIGS. 1 to 3, the carry-in conveyor 1 carries in wood (square wood) 2 having an arbitrary size into a processing line 3 constituted by the conveyor.

The shape measuring means 4 is for measuring the length dimension of the wood 2, the length measuring instrument 5 for measuring the length dimension of the wood 2, the width measuring instrument 6 for measuring the width dimension of the wood 2, and the height dimension of the wood 2. And a height measuring device 7 of The length measuring instrument 5 is of a photoelectric type and is provided along the entry side processing line 3A. The width measuring device 6 is composed of a pair of clamps that are freely moved by a cylinder along the width direction of the wooden piece 2 and an encoder attached to the cylinder. The height measuring device 7 is provided close to the width measuring device 6, and the wood 2
It is composed of a holding bar that can be freely moved up and down by a cylinder in the height direction and an encoder attached to the cylinder. The measurement data from the shape measuring means 4 is
It is sent to the controller described later.

The cutting machine 8 has a function of cutting off the tip of the wooden piece 2 and cutting the wooden piece 2 into a predetermined length in accordance with a command from the controller.

The sanitizing machine 9 is for sanitizing the wood 2 prior to performing processing such as digging and drilling on the wood 2, and operates according to a command from the controller, as shown in FIG. As shown, a pair is provided on both sides of the processing line 3. The blacking machine 9 has a base 10 fixed in parallel with the processing line 3.
A vertical arm 11 movably attached along the base 10, a horizontal arm 12 attached to the vertical arm 11 so as to be vertically movable and horizontally movable, and a scribing pen 13 attached to the tip of the horizontal arm 12. It consists of Scribble pen
13 is a horizontal arm by an actuator (not shown)
Inkjet head mounted on 12 so that it can rotate freely
Ink is supplied from.

The centripetal clamps 15 are respectively installed in the machining lines 3 on the inlet side and the outlet side of the summing machine 9, and the control is performed so that the central axis of the wood 2 to be summed matches the machining line 3. It has a function of fixing the wood 2 in accordance with a command from the vessel.

The lifting conveyor 16 located on the processing line 3 between the pair of black-printing machines 9 is lifted and lowered by the cylinder 17. That is, the lifting conveyor 16 is the wood 2 fixed by the centripetal clamp 15.
When black-printing is carried out, it descends according to a command from the controller in order not to hinder black-printing.

The stopper 18 has a processing line 3 inside the processing line 3B on the outlet side.
It is provided so as to be movable along. The stopper 18
When the wood 2 is cut by the cutting machine 8 and the wood 2 is blackened by the blacking machine 9, the wood 2 is positioned in accordance with a command from the controller.

The controller (not shown) compares the shape measurement data from the shape measuring means 4 with the product shape data of the wood, which is made up of the width, height and length of various product woods stored in advance, and It is judged whether or not the wood 2 can be processed such as grooving and drilling, and if it can be processed, it is processed with the highest yield from the product shape data stored in advance. It is possible to select a product shape of wood, and issue a sanitizing command for sanitizing the wood 2 so that the wood 2 is processed into the product shape thus selected. It has a function to output to.

The carry-out conveyer 19 is provided in the work-out processing line 3B and has a function of carrying out the wood 2 ′ that has been blackened to the outside of the processing line 3.

According to the automatic wood marking device of the present invention configured as described above, the wood is automatically redacted in the following manner.

That is, when the wood 2 is carried into the entrance side processing line 3A from the carry-in conveyor 1, the length measuring device 5 automatically measures the length of the wood 2, and then the width of the wood 2 is measured by the width measuring device 6. The height of the wood 2 is automatically measured by the height measuring device 7.

In this way, the shape measurement data 5 obtained by the shape measuring means 4 are sent to the respective controllers. Based on these measurement data, the controller determines whether or not the wood 2 carried into the processing line 3 can be processed into the product shape stored in advance in the controller. When it is determined that the wood 2 can be processed, a product shape that can be processed with the highest yield is selected, and a sanitizing command is issued to sanitize the wood 2 so that the wood 2 can be machined in the machined shape. Send to 9.

According to this instruction, the sanitizing machine 9 sanitizes the wood 2 that is determined to be workable. That is, the wood 2 is cut to a predetermined length by the cutting device 8, conveyed to the black-printing machine 9, and then fixed in position by the centripetal clamp 15. Then, after the elevating conveyor 16 descends, the sanitizing machine 9 sanitizes the wood 2. That is, the third
As shown in the figure, when blackening the left and right surfaces of the wood 2, the marking pen 13 of the blacking machine 9 horizontally rotates, while
When performing sanitization on the upper and lower surfaces of the wood 2, the scribing pen 13 of the sanitizing machine 9 rotates vertically, and in this state, the vertical arm
By moving 11 and the horizontal arm 12, the wood 2
Blacking is performed on each side of.

The wood 2, which the controller judges to be unworkable, passes through the working line 3 as it is and is carried out of the carrying-out conveyor 19 to the outside of the working line 3.

In this way, all sanitization of the wood 2 is automatically performed.

〔The invention's effect〕

As described above, according to the present invention, an extremely useful effect is obtained that the blacking operation performed on wood prior to the processing of wood can be performed with good yield in a short time and reliably.
