Description

Wood Processing Machine

The present invention relates to a wood processing machine for processing a sheet material, and more specifically, the rough top and bottom surface of the plate can be cut in a certain width after the cutting work in a single wood processing machine, the performance of the surface mill An excellent wood processor.

Plates made of solid wood with a considerable thickness have sharp saw marks on the cut surface, which is rough. Therefore, these rough plates are difficult to use.

Surface trimming is done in wood-only surface machines with face-to-face features.

In addition, the plated board is made of timber by turning it to have a certain width according to the purpose, which is used for cutting.

Above all, the roughing of the top and bottom of the plate and the turning on of the plated wood are performed on two wood machines with different functions. Poor profitability.

In light of this, it is urgent to make it possible to collectively process the rough surface of the plate and to re-timber the plated plate with a predetermined width.

On the other hand, the surface roughening machine that roughly roughens the top and bottom surfaces of the plate could only process the end face.

Therefore, to chamfer both sides, it has to go through two rounds. As such, the cutting operation efficiency was low and the processing cost was relatively high.

In addition, it was not necessary to equalize the thickness when the top and bottom surfaces of the sheet were chamfered.

This is because it does not have a function to adjust the thickness of the noodles.

In order to obtain the even quality wood, it is necessary to accurately determine the cutting thickness according to the roughness, so the reliability of the quality of the processed wood has to be low.

On the other hand, the plate material also differs in the cutting resistance received by the cutter, the driving motor, the feeding means, etc., depending on the roughness of the surface to be faced.

That is, the cutting resistance is small when the weak part is chamfered, but the cutting resistance is large when the rough surface is chamfered.

In this case, the cutting speed of the plate is usually artificially controlled to be fast or slow in the case of receiving a small cutting force and vice versa.

If the surface of the board is normal and suddenly receives a large cutting resistance at any point, the machining operation temporarily stumbles and the machining state is poor, and there is a great deal of pressure on the cutter and motor as well as the driving force relay that connects these elements dynamically. Is applied.

It is too inefficient to artificially adjust the feed rate of the plate according to the cutting resistance of the plate.

The object of the present invention is to provide a wood processing machine which can efficiently process the surface treatment machine, various functionalities, and turn-on and turn-off work in one wood processing machine.

This task is to cut the plate of the upper and lower sides of the plate with the upper and lower cutters straight from the cutting machine connected to the discharge end and cut it to a predetermined width. This can be achieved by providing a structured wood cutting machine.

In Figure 1, the wood processing machine combines the cutting machine 40 for turning on the plated plate to a predetermined thickness in the discharge end of the surface roughening machine 10 to smooth the rough top and bottom of the plate in a row to achieve a specific problem. It is characterized by the configured points.

Referring to FIG. 2 with respect to the face grinder 10, as a type of wood processing machine that smoothly smoothes rough surface such as saw marks remaining when turning on the input of the plate material of a considerable thickness in a separate wood milling machine. , The lower cutter 12 and the guide roller 13 installed on the upper surface of the planar body 11, the upper cutter 15 and the feed rollers 16 and 16a installed on the head 14, and the face thickness adjusting device to be described later. 20 and an electric drive 30 that exhibits a function of adjusting the cutting speed according to the cutting resistance.

The lower cutter 12 is a cutting tool for chamfering the bottom surface of the plate, and is located close to the inlet side of the plate, and the upper cutter 15 is a cutting tool for trimming the upper surface of the plate. The lower cutter 12 is located on the head 13 away from the main body 11. It is arrange | positioned at the back of (12).

In addition, the lower cutter 12 and the upper cutter 15 are respectively connected to the motors M1 and M2 in a dynamic manner so as to sequentially rotate the bottom surface and the upper surface of the plate, which are inserted while rotating at a high speed in the opposite direction to the plate feeding direction. By grinding, the cutting resistance at the time of grinding is lowered.

The guide roller 13 is disposed before and after the lower cutter 12 to hold the plate stably in the process of chamfering the plate after input and input so that the guide roller 13 can be effectively chamfered and discharged in place according to the weight of the plate and the moving speed thereof. The empty road is idle.

The head 14 accommodates the upper cutter 15 and the feed rollers 16 and 16a. The head 14 is mounted on the slider 22 of the chamfering thickness adjusting device 20 to be described later and always floats on the upper surface of the main body 11. In addition, the surface thickness of the sheet is determined by adjusting the height of the surface roughness roughening device 20 by the distance between the lower cutter 12 and the upper cutter 15.

The feed rollers 16 and 16a disposed before and after the upper cutter 15 are to push the raw sheet portion and the faceted plate portion without hitch in the direction to be taken out after processing, and the feed rollers 16 and 16a. The pressure roller 16 disposed at the potential of the upper cutter 15 is formed to have a rough main surface in order to increase the pressure feeding force, and the pressure roller 16a disposed at the rear thereof has a mark on the plate surface when the plated sheet is taken out. The main surface is formed smoothly so that it does not come out.

The head 14 is inserted into a vertical roller groove 18 perforated in various places of the head 14 by standing one screw rod 17 at the front and rear ends thereof, and the adjustment nut installed on the upper surface of the head 14 ( 19) by adjusting the height so as not to impede the role of conveying the plate according to the change of the cutting depth with respect to the upper surface of the plate.

1 and 3, the cutting thickness adjusting device 20 is mounted on the front and back of the surface of the surface machine main body 11 to determine the thickness of the plate by determining the cutting depth of the upper surface of the plate by adjusting the height of the head 14 The left and right pairs of longitudinal rails 21 are mounted side by side on the front and rear surfaces of the surface chamfering machine 11, and the sliders 22 rising and falling in the rail direction are inserted into the longitudinal rails 21 of each side, and the slider 22 At the upper end of the head 14, the head 14 is mounted to determine the surface thickness of the plate by the lifting width of the slider 22, and the slider 22 is pushed up by inserting the screw rod 23 at the lower end of the slider 22, or To be pulled down.

The screw rod 23 is connected to the output side of the reducer 24 installed on the base of the face machine main body 11, and the handle 25 is attached to the opposite side of the output shaft of the reducer 24 to operate the screw rod 23. ), The lifting and lowering of the slider 22 is realized.

The input shaft of the speed reducer 24 is connected to the motor shaft of the motor M4 for the convenience of the electric-manual combined use, and the surface roughness of the plate is precisely operated by turning the handle 25.

In this figure, the motor M1 is the driving means of the lower cutter 12, and the other motor M2 is mounted on the slider 22 on one side as the driving means of the upper cutter 15. As shown in FIG.

Another motor M3 is the driving means of the pressure roller 16, 16a.

Sprockets 16b of the same size are mounted on the shaft ends of each of the pressure rollers 16 and 16a exposed to one side of the head 14, and they are connected to the invisible driving sprockets by a chain 16c by the motor M3. As a result, the sheet material is pressed in the same direction.

In Fig. 4, after the output of the motor M3 is decelerated in the reducer, the driving force is transmitted to the roller shaft S of the pressure roller 16a, and the output shaft 32 and the roller shaft S of the reducer are universal joints ( 33), the power of the motor M3 is transmitted to the roller shaft S without a hitch even when the height of the drive-side pressure roller 16a is changed.

By the way, when looking at the plate in the surface machine 10, the progress of the plate may suddenly flicker.

This often happens when the cutting thickness of the plate does not follow the cutting capability of the upper and lower cutters 15 and 12, and there is a protrusion on the cut surface of the plate, which impedes cutting.

In this case, if the upper and lower cutters 15 and 12 do not follow the feed rollers 16 and 16a at the constant speed, the upper and lower cutters 15 and 12 and the feed rollers 16 and 16a and the motor, respectively. (M3), the electric drive (30), etc. are all considerable.

The drive mechanism 30 of FIG. 5 is to prepare for such a case, and the output shaft 32 of the reducer and the roller shaft S of the driving side feed roller 16a are connected to the universal joint 33, and When the output shaft 32 and the input end of the universal joint 33 are connected to the friction clutch 34 and a load is applied to the roller shaft S, the output friction plate 35 of the friction clutch 34 and the input friction plate of the universal joint 33 are applied. Although the sliding phenomenon occurs between the 36 and the power of the reducer remains the same, the rotational force through the universal joint 33 is attenuated by a load corresponding to the load on the roller shaft S, so that the feed rollers 16 and 16a are moved up and down. It is a kind of differential electric machine which did not consider the ability of the cutters 15 and 12 to avoid the inadvertent situation of conveying a board | plate material by force.

In FIG. 6, the cutting machine 40 cuts and unloads the board | plate material which is chamfered from the surface grinder 10 to predetermined width, and is disclosed by Utility Model Registration No. 220753 which is owned by me.

For reference, on the base 41, an endless track caterpillar 42 which feeds the sheet material cut in the direction in which the sheet is cut out is provided to pivot the track by the motor 43, and the The rotary saw 45 provided in the orthogonal direction to this in the upper direction is configured to cut out the faceted sheet material fed from the feeding side 46 with a predetermined width while being rotated at high speed by the motor 44.

The rotary saw 45 may be loaded in plural and may change the distance between the rotary saws 45 from the single rotary shaft 47 to the sleeve-type spacer 48.

Next, the process of the roughing and cutting of the rough surface of the plate by using the surface grinder 10, the surface thickness adjusting device 20, the power mechanism 30, the cutting machine 40 will be described.

The height of the upper cutter 15 is adjusted by rotating the screw rod 23 with the motor M4 or the handle 25 in accordance with the thickness of the plate to be chamfered.

When the height of the head 14 changes, an angle difference arises between the output shaft 32 and the roller shaft S of the speed reducer mounted in the surface treatment machine main body 11.

Since this angular difference is handled by the universal joint 33, there is no problem in that the power of the motor M3 is transmitted to the roller shaft S. FIG.

After operating the face grinder 10 and the cutting machine 40, if the board | plate material A is thrown in between the main body 11 and the head 14 of the face grinder 10 in the D direction of FIG. The pressure roller 16 is in close contact with the pressure roller.

Then, from the moment the bottom end of the plate A comes into contact with the lower cutter 12, the bottom surface is cut, and then the upper surface is cut while passing under the upper cutter 15.

In this process, when the progress of the sheet material A is temporarily faltered because the lower cutter 12 and the upper cutter 15 are not able to perform the grinding operation in a timely manner, the friction clutch 34 performs an immediate function so that the roller shaft Attenuate the output of the reducer delivered to (S) as much as the cutting resistance.

After that, when the cutting resistance which has hindered the cutting of the plate (A) disappears, the output of the reducer is immediately recovered, and is transmitted to the roller shaft (S) as it is, so that the grinding operation is normally performed.

The plate A subjected to the chamfering operation is immediately directed to the cutting machine 40, and when the faced plate A is moved to the cutting machine 40, the caterpillar 42 is transferred to the cutting machine 40 in the cutting direction to transfer the rotary saw 45. Let it go.

The plate A is cut at the intervals of the placement of the rotary saw 45 and then loaded on the caterpillar 42 to be taken out of the cutting machine 40.

The wood processing machine according to the present invention can cut the rough upper and the bottom of the plate input by combining the cutting machine into the face cutter, and then process the machined into the plate having the predetermined thickness by cutting it straight to the cutting machine so that it can be cut to a predetermined width on the spot. There is an advantage that it is possible to perform the processing of the sheet and the batch processing of the plated plate very efficiently.

In addition, the surface thickness adjustment device mounted on the surface treatment machine is convenient to freely adjust the processing thickness of the plate, and the differential power mechanism can overcome the sudden cutting resistance situation in the course of the plate during the grinding process, it can overcome the plate without problems It is a very useful design that has the effect of obtaining a good quality plate by performing the grinding work.
