Abstract

PROBLEM TO BE SOLVED: To enable a foot switch for lifting up and down a table or a head to be used on the side of an operator on a woodworking machine. SOLUTION: A table 3 is actuated to ascent/descent by a foot switch part 9, and pins 13 are provided on a part of a hand-push table 7, and further, holes for engagement are formed on the foot switch part 9 so that the holes are engaged with the pins 13. Thus the foot switch part 9 can be used as an on-hand switch by hooking the part 9 on the pins 13, when a small-size wood or a small quantity of material is lifted up and down.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foot switch for raising and lowering a table or a head of a woodworking machine such as an automatic planer or a super-finish planer.

[0002]

2. Description of the Related Art Conventionally, in a wood processing machine such as an automatic planer board or a super-finish planer board, a lift switch for raising and lowering a table or a head is connected to a body and can be operated remotely by a foot switch or a body. There is a hand switch built into the main unit.

[0003]

[0006] Both the foot switch and the hand switch have advantages and disadvantages. In the former case, when a long material is supported on the table, the operator can lift and lower the table with a foot even if he is away from the body to hold one end of the material. Although the inching operation is performed, there is a problem that the inching operation is difficult because the switch is operated by stepping on the foot.
In the latter case, when the switch is inchingly operated for manual operation, a small amount of elevating operation can be performed, whereas when a long material is supported on the table as described above, the elevating operation is performed because it is separated from the body of the body. There was a problem that could not be done.

As described above, the foot switch and the hand switch have contradictory problems. If both switches are provided, the above problem can be solved, but there is a problem that the cost increases.

An object of the present invention is to solve the above-mentioned problems of the prior art and to enable both remote operation and inching operation of a switch with an inexpensive configuration.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a woodworking machine in which a table or a head moves up and down, wherein a switch for moving the table or the head up and down is operated as a foot switch which can be operated separately from the machine body. This is achieved by providing mounting means for detachably mounting the foot switch.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a side view of an automatic planer with a hand-carrying part, FIG. 2 is a side view showing a state in which a foot switch is hooked on a hand-held table in FIG. 1, and FIG. FIG. 4 is a sectional view taken along line BB of FIG. In the present embodiment, an automatic planer with a hand-operated planer of a table elevating type will be described as an example of a woodworking machine.

In the figure, a table 3 is moved up and down by using a column 2 erected on a base 1 as a guide. A head 4 is fixed to the upper end of the column 2, and the material placed on the table 3 is cut by a planer blade 5 provided in the head 4. The side of the head 4 has a hand pusher 6.
The hand pusher section 6 includes a hand push table 7 on which the material is placed and a planer blade (not shown) for cutting the material. An elevating motor 8 for automatically elevating and lowering the table 3 is provided below the table 3, and the elevating and lowering of the table 3 is operated by a foot switch unit 9 connected to the body. Foot switch section 9
Is composed of two foot switches 10 and 11 and is provided on the mounting member 12. The table 3 is raised by one foot switch 10, and the table 3 is lowered by the other foot switch 11.

As shown in FIGS. 3 and 4, a pin 13 serving as an attachment means is screwed on a side surface of the hand pushing table 7, and a gourd-shaped hole 12a is formed in the attachment member 12. By passing the hole 12 a through the pin 13, the foot switch 9 can be hooked on the side surface of the table 7 for pushing.

In the above construction, the long material is placed on the table 3
When the table 3 is to be lifted and lowered by being placed on the top, the foot switch section 9 is usually separated from the main body, and the foot switches 10 and 11 are operated by stepping on the ground. When the small body can be operated on the body side, such as when the small material is placed on the table 3, or when a small amount of elevating is to be performed, the hole 12a of the mounting member 12 is passed through the pin 13 and the foot switch 9 is connected to the side of the hand pushing table 7. If it is hooked on, it can be moved up and down by hand, and it can be used as a hand switch.

As another embodiment, in the case of FIGS. 5 and 6,
A hook 14 serving as an attachment means is provided on a side surface of the head 4, and the hook 14 has a width capable of accommodating the foot switch section 9.
The hook 14 is attached to the mounting member 12 of the foot switch 9.
The foot switch unit 9 is supported on the side surface of the head 4 and can be operated as a hand switch. FIG.
In this case, the pin 13 is screwed on the side surface of the table 3 and hooked on the pin 13 in the hole 12 a of the foot switch portion 9, whereby the foot switch portion 9 can be leaned on the side surface of the table 3.

FIG. 8 shows an embodiment in which the table 3 is fixed and the head 4 is moved up and down by an automatic planer with a hand-operated planer.
As in FIG. 1, the pin 13 is screwed on the side surface of the hand pushing table 7 and the hole 12 of the foot switch portion 9 is hooked on the pin 13, so that the foot switch portion 9 is hooked on the side surface of the hand pushing table 7. Can be. Although not shown, the same effect can be obtained by attaching the foot switch unit 9 to the head 4 as shown in FIG. 5 or the table 3 as shown in FIG.

[0013]

According to the present invention, the foot switch is detachably attached to the body, so that when the foot switch is detached from the body, the foot switch is used for remote control.
If attached to the fuselage, it can be used as a hand switch.
