Description

[Detailed Description of the Invention] The present invention relates to an automatic planing machine, and more particularly, to a planing machine body having heads at the upper ends of a plurality of columns provided upright on the base, the base is connected to a reversible electric motor. This invention relates to an automatic planing machine equipped with an automatic table that slides on the column and moves up and down by a lifting screw provided in the column.

Conventionally, when finishing wood to a desired thickness using this type of automatic planer, if the amount to be cut exceeds the maximum depth of cut, it is necessary to cut the wood in several steps to the final finished thickness.

Furthermore, when cutting a large number of pieces of wood with different thicknesses at a depth that exceeds the maximum depth of cut of an automatic planer, it is necessary to adjust the cutting size to the final finished size each time, resulting in poor workability.

An object of the present invention is to provide an automatic planer that eliminates the above-mentioned drawbacks and can perform cutting operations efficiently.

The present invention consists of a plane board body having heads at the upper ends of a plurality of columns installed upright on a base, and a lifting screw installed on the base that is linked to a reversible electric motor to slide the columns. In an automatic plane machine that is equipped with an automatic table that moves up and down by a rotary plane blade and performs cutting using a rotary plane blade, the end portion is fixed to the plane body, and the position setting member provided along one of the columns has the above-mentioned A detection piece for detecting the position when the automatic table is raised can be set to a latched state, and a detector is provided to engage with the detection piece to stop the automatic table from rising. That is.

Hereinafter, one embodiment of the present invention will be described based on the drawings. Figure 1 is a front view of the automatic plane machine of the present invention, Figure 2
The figure is a detailed view of part A in Figure 1, Figure 3 is a view taken in the direction of arrow B in Figure 2, and Figure 4 is a block diagram showing the operating circuit of the present invention, where 1 is an automatic table, 2 is a base, and 3 is a head, 4 is a column, 5 is a lifting screw, 6 is a reversible electric motor, 7 is a holding member for holding the detector 8 on the automatic table 1, 9 is a dimensional scale, and 9 is a dimensional scale that covers both sides of the dimensional scale in the vertical direction. This is a position setting member in which a detection piece 10 is slidably provided, and a ball 11 is provided on the detection piece 10 to apply a pressing force by a compression spring 12 provided to prevent escape by a set screw 13. The ball 11 is engaged with one of the plurality of recesses provided on the side surface of the position setting member 9 so that the table 1 can be stopped at a frequently used material feeding interval (the interval between the rotary plane blade and the automatic table 1). The detection piece 10 can be set to a latching state by matching the detection piece 10. In addition, 14 and 15 are normally open switches, 16 and 19 are relay coils, 17 and 20 are normally closed relay contacts, 18 and 21 are normally open relay contacts, and 2
2 indicates a single-phase AC power supply, and Vcc indicates a DC power supply voltage.

In this embodiment, a planer main body is provided with a head 3 at the upper end of a plurality of columns 4 provided upright on a base 2, and a lifting screw 5 provided on the base 2 so as to be interlocked with a reversible electric motor 6. In an automatic plane machine of a conventional structure, which is equipped with an automatic table 1 that moves up and down by sliding a column 4, and performs cutting with a rotary plane blade,
A detection piece 10 that detects the position of the automatic table 1 when it is raised is attached to a position setting member 9 whose end is fixed to the planer body and is provided along one of the columns 4.
is provided so that it can be set to a latched state, and a detector 8 is provided so as to engage with this detection piece 10 to stop the automatic table 1 from rising.

That is, as shown in FIG. 2, the detector 8 is installed on the automatic table 1, and the automatic table 1
rises and the protrusion 8' of the detector 8 moves to the detection piece 10.
The automatic table 1 is stopped by contacting the protrusion 10' of the table. In this case, the detection piece 10 can be set in a latching state by engaging the ball 11 in a recess provided in the position setting member 9 so that the feeding interval becomes the set dimension C.

In Japanese architecture, if it is bamboo wood, it is 1 sun 5 minutes square.
For pillar materials, 3 dimensions and 5 minutes square and 4 dimensions are common. In this way, 1 sun 5 minutes, 3 sun 5 minutes, 4 sun etc.
Since the automatic table 1 can be stopped at frequently used material feeding intervals, it is possible to efficiently cut a large number of pieces of wood having different thicknesses.

Next, the setting of the material feeding interval and the operation of detecting the position and stopping the automatic table 1 via the detector 8 in this embodiment will be explained.

First, from among the plurality of recesses provided in the position setting member 9, a recess with a required material feeding interval is selected and the detection piece 10 is set in the latched state. Here, when the normally open switch 14 is turned on, the relay coil 1
6 is energized, the normally open relay contact 18 is energized, the reversible motor 6 rotates, the lifting screw 5 rotates via the gear, and the automatic table 1 begins to rise. and,
When the detector 8 contacts the detection piece 10 and is opened,
Relay coil 16 is demagnetized and normally open relay contact 18
is deenergized, the rotation of the reversible electric motor 6 is stopped, and the automatic table 1 can be stopped at the position of the set material feeding interval. In this case, the locking position of the detection piece 10 and the mounting position of the protrusion 10' are determined taking into account the inertia of the reversible motor 6, the sliding resistance when the automatic table 1 is raised and lowered, and the like. Note that the position setting member 9 can be provided with an end fixed to either or both of the head 3 and the base 2.

As explained above, according to the present invention, 1 inch 5
The automatic table can be easily stopped at frequently used material feed intervals such as minute, 3-inch, 5-minute, 4-inch, etc., so even when cutting a large number of pieces of wood with different thicknesses to a fixed finished size, the operation is easy. Practical effects can be achieved in that time can be shortened and cutting work can be performed efficiently.
