Description

[Detailed description of the invention] This invention is a woodworking machine, such as a manual planer, in which a ruler plate is vertically perpendicular to the surface plate, and the ruler plate is attached to the ruler plate to press the workpiece from an oblique direction. The purpose of the present invention is to provide a feed device for a woodworking machine that is capable of retracting the feed roller from the transfer path of a workpiece when the feed device is not in use. be.

Hereinafter, the illustrated embodiment embodying the present invention will be described in detail. The drawing shows the case where the proposed feeding device is implemented in a hand planing machine, and a surface plate 2 is mounted on the upper part of the machine base 1 of the hand planing machine. A ruler plate 3 is disposed horizontally at one end of the surface plate 2 in the longitudinal direction and is perpendicular to the surface of the surface plate 2 .

In addition, a cutting tool (not shown) such as a planer blade is installed in a notch formed in the transverse direction at approximately the center of the surface plate 2 in the longitudinal direction.

The feeding device is installed on the side of the ruler plate 3 from which the workpiece W is fed with respect to the cutting tool (on the left side in FIG. 1), and a fixed bracket is installed on the upper surface of the ruler plate 3 at an angle of approximately 45°. 4 is fastened diagonally, and on this fixed bracket 4 there is a support hole 5 for supporting a swing bracket, which will be described later. First and twentieth locking holes 6 and 7 are provided at two locations, respectively.

A swing bracket 9 is rotatably mounted on the fixed bracket 4 with a support shaft 8 that fits into the support hole 5, and the base end of the swing bracket 90 has a shape shown in FIGS. 3 and 7. The support bulges 10, 10 project upward, and furthermore, a support piece 12 is integrally formed in one of the sides thereof, through which a locking hole 11 corresponding to the first and twentieth locking holes 6, 7 is formed. prominently.

Further, a stopper piece 13 is integrally projected from the other side.

Note that the swing bracket 9 also has an oblique shape with respect to the ruler plate 3, similar to the fixed bracket 4.

Reference numeral 14 denotes a supporting member in which a mounting piece 14a and a support piece 14b are integrally formed in a substantially L-shape. The support member 14 is tiltably supported by a support shaft 15 relative to the support bulges 10, 10 of the bracket 9, so that the support member 14 is tilted in the same direction as the feed direction of the workpiece W.

Note that a part of the mounting piece 14a is brought into contact with an adjusting screw rod 16 screwed into the fixing bracket 4, so that a tilting range in the clockwise direction in the figure is restricted, and the support member 1
The support piece 14b of No. 4 has two dovetails 18, 18 formed in the longitudinal direction of one side with a groove 17 between them, and within this groove 17, a screw shaft 20 with a handle 19 at the upper end is rotatably mounted. Supported.

21 is a roller shaft head and a support piece 14bK of the support member 14
On the other hand, it has dovetail grooves 22°22 that fit into the dovetails 18 and 18,
The screw shaft 20 is slidably attached to the screw shaft 20 with a boss portion (not shown), and a roller shaft located at an angle of 45 degrees with respect to the ruler plate 3 is located in the center of the screw shaft 20. 2
3 is rotatably supported, and one end (right side in FIG. 2) of this roller shaft 23 is connected to a drive motor 24 attached to the roller shaft head 21 via a speed reduction mechanism (not shown). The other end is located above the surface plate 2 and is provided with a threaded portion.

Fixing nuts 25 are attached to the threaded portion of the roller shaft 23 from both sides.
A feed roller 26 is fixed so that its position can be adjusted, and this feed roller 226 is made of rubber or the like,
On both sides thereof, pressing surfaces 26at26b are formed which are parallel to the surface plate 2 and the ruler plate 3, respectively.

Therefore, the supporting member 14 is always moved in a clockwise direction as shown in FIG. The feed roller 26 is configured to be inclined downward in the direction so that its weight is applied to the contact portion of the feed roller 26 with respect to the workpiece W.

As shown in FIG. 7, the pivoting bracket 9 is connected to the fixed bracket 4 by a fixing pin 27 that is fitted into the engagement hole 11 of the support piece 12 and is connected to the first and second engagement holes 6, 7.
When the insertion hole 11 of the support piece 12 and the tenth locking hole 6 match and are fixed by the fixing pin 27, the feed roller 26 is fixed to the surface plate 2. When the support member 14 is positioned on the transfer path of the upper workpiece W, and the engagement hole 11 and the 20th locking hole 6 are aligned and fixed by the fixing pin 27, the support member 14 is moved around the support shaft 15 The feed roller 26 is positioned such that it is tilted in the feeding direction of the workpiece W, and the feed roller 26 is retracted from the transport path of the workpiece W.

The feeding device of this embodiment is configured as described above, and to explain the case of transferring the workpiece W, first, when the handle 19 on the support member 14 side is operated and the screw shaft 20 is rotated. The roller shaft head 21 is connected to the support member 14 with the roller shaft 23, the dovetails 18, 18, and the dovetail groove 22.
22, it is moved diagonally up and down in the direction of the arrow in the figure.

Further, the fixing nuts 25 of the roller shafts 23 are screwed back from the feed rollers 26, and the feed rollers 26 are attached to the roller shafts 23.
2 in the left-right direction in FIG.

Then, by performing the above-mentioned two actions appropriately, the roller shaft 23 is
The feed roller 26 of
a is pressed against the upper surface of the workpiece W from an angle of 45 degrees.

Therefore, when the drive motor 24 is driven and the roller shaft 23 is rotated via the deceleration mechanism, the feed roller 26 rotates together and automatically presses the workpiece W against the surface plate 2 from an angle of 45 degrees. During this transfer, desired machining is performed using the cutting tool □.

In this case, the workpiece W is pressed against the surface plate 2 by the feed roller 26 at an angle of 45 degrees, and its side surface is also brought into contact with the ruler plate 3.

Therefore, the transfer along the ruler plate 3 is reliably carried out,
As a result, in planer machining, so-called perpendicular machining of the workpiece W, in which the machining surface is at 90° to the side surface abutting the ruler plate 3, can be carried out very reliably, automatically, and safely.

Further, in this case, since the structure is such that the weight of the support member 14, the roller shaft head 21, and each member attached thereto is applied to the contact portion of the feed roller 26 with respect to the workpiece W, In the above-described feeding state, the feed roller 26 reliably presses the workpiece W without lifting up from the workpiece W.

That is, in a state in which the mounting piece 14a of the support member 14 is lifted from the inclined upper surface of the swing bracket 9, the support member 14 is tilted clockwise in FIG. 3 with respect to the swing bracket 9 about the support shaft 15. Therefore, the weight of each member described above is always added to the portion where the feed roller 26 contacts the workpiece W, and the workpiece W can be pressed more reliably.

The feeding device of this example is for transporting the workpiece W as described above, and the feeding device 26. That is, when the feeding device is not used, first, as shown in FIG. After the fixing pin 27 that fixes the rotating bracket 9 and the fixed bracket 4 is removed from the tenth locking hole 11, the pivot bracket 9 is moved relative to the fixed bracket 4 by the supporting shaft 8. The engagement hole 11 of the support piece 12 and the 20th engagement hole 7 of the fixation bracket 4 are rotated approximately 90 degrees along the oblique upper surface of the fixation bracket 4 as a center and are displaced together with the rotation bracket 9. Then, the fixing pin 27 is inserted into the engagement hole 11 and the 20th locking hole 7, and the swing bracket 9 is fixed on the fixed bracket 4 (see FIG. 5).

Therefore, since the support member 14 is pivoted together with the pivot bracket 9, the feed roller 26 is retracted from the transport path of the workpiece W.

(See FIGS. 5 and 6) In this case, the tilted state of the support member 14 is maintained by a part of the support member 14 being supported in contact with the stopper piece 13 of the swing bracket 9.

In addition, when returning the feeding device to its original state, the procedure is reversed to that described above.

As described above, in the present invention, in a woodworking machine □ that carries out a desired cutting process by transporting a workpiece along a surface plate and a ruler plate vertically installed on the surface plate, A fixed bracket is mounted obliquely, a swing bracket is mounted on the fixed bracket so as to be able to swing within a predetermined range, a support member is provided on the swing bracket so as to be tiltable, and the workpiece is mounted on this support member at an angle. A feed roller is installed to suppress and transfer the workpiece from the fixed bracket, and the feed roller is positioned on the transfer path of the workpiece between the surface plate and the ruler plate when the workpiece is transferred to the fixed bracket. □The feed roller is configured to be placed in a fixed position and to be pivoted relative to the fixed bracket when not in use to evacuate the feed roller from the transfer path, and the feed roller is configured to be oriented between the workpiece transfer position and the retraction position. A locking means is provided for removably locking the swing bracket to predetermined positions of the fixed bracket corresponding to the transfer position and the retracted position of the feed roller, respectively, for selective positioning. This not only makes it possible to ideally transfer the workpiece using the feed roller that presses from an oblique direction, but also enables transfer without using the feed roller without having to remove the entire device. The support member equipped with the rollers can be evacuated from the workpiece transfer path by a simple operation of rotating together with the rotation bracket, and has the advantage that this transfer can be handled very easily.
