Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a grooving machine, and more specifically, for example, by cutting vertical grooves, a plurality of band-shaped unit plate parts are formed between the vertical grooves. A processing machine is used to cut horizontal grooves into decorative board materials made of wood to further enhance the decorative effect.

BACKGROUND TECHNOLOGY This type of grooving is known as a processing machine, for example, in
No. 9502, Utility Model No. 189104, Utility Model Application No. 1983
-189105, those described in each publication can be mentioned. These groove processing machines generally have a bar (52) equipped with a cutting body (51), as shown in FIG.
A pair of left and right cylinders (53) (
The bar (52) is moved by connecting to the piston rod (54) (54) of the cutting body (51) and driving both cylinders (53) (53) in synchronization.
A horizontal groove is cut into the workpiece (55) at the step. Then, vertical grooves (56) of the workpiece (55)...the number of bars (52) corresponding to the number of band-shaped unit plate parts appearing between them (four in this case) are arranged in parallel, Each bar (52)... is equipped with a drive mechanism similar to the above, and the cutting body (
51)..., horizontal grooves are cut into the corresponding band-shaped unit plate portions. Furthermore, the above grooved grooves are used in a processing machine to provide a pair of upper and lower rails (
57) (57) are arranged, and an appropriate number of upper surface positioning members (58) are installed between both rails (57) (57) at the lower position of the bar (52). (58)...The upper surface of the workpiece (55) that is being pushed up from below is fixed by the upper surface positioning member (58).
... to make the upper surface of the workpiece (55), that is, the surface on the side where the lateral groove is to be cut, flattened, thereby controlling the depth and width of the lateral groove formed by the cutting body (51). It is made to remain constant.

Problems to be Solved by the Invention The above-mentioned grooving machine has the following problems. First, when it is necessary to change the cutting depth of the lateral groove or the cutting position of the lateral groove in the lateral direction depending on the type of workpiece (55), the bar (52) moves in a balanced manner from side to side. In order to be able to do this, it is necessary to adjust the cylinders (53), (53), etc. so that they are driven symmetrically, but this adjustment requires a lot of effort. Secondly, if the length of the horizontal groove to be cut is short, especially if the length of the horizontal groove is shorter than the width of / This is a problem in that it is physically difficult to cut such lateral grooves. Thirdly, when it is necessary to process workpieces with different numbers of vertical grooves, for example, when the above-mentioned grooved processing machine has five band-shaped unit plate parts of the workpiece, grooved It is necessary to add a new set of bars etc. to the processing machine, but this problem is difficult because the dimensions of each bar etc. are different. Fourth, a pair of left and right cylinders (53) (53)
Since the configuration is such that the bar (52) is moved by the
As a result, the problem with grooving is that the entire processing machine becomes larger. Fifthly, in order to keep the depth and width of the lateral groove constant, the lateral groove cutting portion of the workpiece (55) is flattened, that is, the upper surface positioning member (58)... is attached to the workpiece (
The workpiece (55) is supported by being brought into contact with the machined surface of the workpiece (55), but with this method, some deflection still remains in the workpiece (55), so the depth and width of the lateral groove cannot necessarily be made constant. This is the problem.

This invention was made to solve the various problems mentioned above, and its purpose is to easily adapt to changes in the length of the lateral groove to be cut and the position of the lateral groove in the lateral direction.
Grooving can also be done even when the length of the horizontal grooves to be cut is very short, and it can also be easily accommodated when the number of vertical grooves changes, especially when it increases. Our goal is to provide processing machines.

Another object of the present invention is to provide a groove processing machine that can be constructed compactly as a whole.

A further object of the present invention is to provide a grooving machine that can make the depth and width of the lateral grooves to be cut constant.

Means for Solving the Problem Therefore, the groove processing machine according to claim (1) of the present invention has the following features:
Consisting of fixed rails that are parallel on both sides, and a movable cutting unit that is installed on both fixed rails, the cutting unit includes a transverse bar, a cutting body that is movably attached to the transverse bar, and a cutting unit that is movably mounted on the transverse bar. The gist of the present invention is to include a driving means for driving the cutting body on the transverse bar, and a regulating means for regulating the driving range of the cutting body.

Further, the gist of the grooving machine according to claim (2) of the present invention is that the driving means is a rodless cylinder.

Furthermore, the groove processing machine according to claim (3) of the present invention includes:
The gist of the present invention is to include a tracing cutting mechanism for causing the cutting body to follow the surface shape of the workpiece while the cutting body is moving.

Effect As a result of the above, in the grooving machine according to claim (1), for example, a number of cutting units corresponding to the number of lateral grooves to be cut are installed on the fixed rail.

Then, each cutting unit is moved and displaced as appropriate along the fixed rail to determine the vertical position where the horizontal groove should be cut, and in each cutting unit, the cutting body cuts the horizontal groove at the position of the band-shaped unit plate. The driving range is adjusted in each regulating means so that it is possible to do so. Next, each cutting body is driven by each driving means, and the lateral groove is cut within the above driving range.

Here, if the length of the lateral groove to be cut and the position of the lateral groove in the lateral direction are changed depending on the type of workpiece, the cutting body drive range will be adjusted according to the changed length and position. Regulatory measures need to be readjusted. In addition, the cutting units do not interfere with each other in the lateral direction, so the cutting body can move over almost the entire area on the transverse bar, and the drive range of the cutting body can be adjusted appropriately at any position on the transverse bar. Therefore, if the length of the lateral groove to be cut is very short, the cutting body drive range can be regulated according to the length of the lateral groove at the corresponding position. A horizontal groove like this will be cut. In addition, when the number of vertical grooves on the workpiece is changed, especially when it is increased, by adding a pre-prepared cutting unit to the fixed rail and installing it, the horizontal grooves can be cut into the increased band-shaped unit plate. Try to remove it.

Further, in the groove processing machine according to claim (2), by using a rodless cylinder as a driving means, this rodless cylinder also serves as a transverse bar.

Furthermore, in the processing machine, the grooving according to claim (3) allows the cutting body to be cut by the profiling cutting mechanism during horizontal groove cutting even when the cutting surface of the workpiece is curved or uneven. It will move following the shape of the surface.

Embodiment Next, an embodiment of the groove processing machine of the present invention will be explained based on the drawings.

1 to 10 show an embodiment of the present invention. In Figures 1 and 3, (1) and (1) are digits,
A pair of rail support frames (2) (2) on both sides are supported in parallel between these girders (1) (1). As shown in FIG. 3, a workpiece support stand (4) that supports a workpiece (3) is arranged below the rail support frame (2) (2), and this workpiece support stand (4) is equipped with a cylinder. Mechanism (5
) (5) allows it to be raised and lowered. The fixed rails (
6) (6) is laid, and both fixed rails (6) (6)
A cutting unit (7)... is installed.

As shown in FIGS. 4 and 5, the cutting unit (7) includes a transverse bar (6) extending across the fixed rails (6) (6).
8). Rail sliding members (9) (9) are attached to both ends of this lateral 'lfr bar (8), respectively, and the fixed rails (6) (6) are connected to each other via these rail sliding members (9) (9). It is movably supported on the top. Furthermore, as shown in Fig. 5 and Fig. 8, the fixed rail (6) (
6) has an inverted trapezoidal cross section, and by fitting the rail sliding members (9) (9) into this, it can be fixed even if an upward force is applied to the cutting unit (7). It is made so that it does not come off the rail (6) (6). Further, as shown in Fig. 4, a screw (10) is screwed into the rail sliding member (9) (9) from the side, and this screw ([0) causes the rail sliding member (9) (9) to be screwed into the rail sliding member (9) (9). , and in turn, the cutting units (7)... are fixed at appropriate positions along the fixed rails (6) (6).

On the other hand, a cutting body (11) is attached to the transverse bar (8), as shown in FIG. As shown in FIGS. 4 to 6, this cutting body (11) has a boss ( 13), and is movable on a transverse bar (8). In this case, as shown in FIG. 6, since the outer circumferential shape of the transverse bar (8) is circular, in order to prevent the slider (12) from rotating, the rail sliding members (9) (9) The slider (12) is provided with a guide (15) that slidably engages with an upper surface guide (14) installed between the sliders and the upper surface guide for holding down the upper surface of the workpiece (3). Note that the support structure of the cutting body (11) with respect to the boss (13) will be described later.

By the way, the above-mentioned transverse bar (8) is constituted by a rodless cylinder (16) as a driving means. That is, as shown in principle in Fig. 10, the cylinder tube (1
7) A boat (18) provided at each end of the
The piston (20) is moved by the action of compressed air supplied by operating the solenoid valve (19) from either side of (18), and the slider (12) is moved by the magnetic force of the magnet (33). It is something.

Further, on the outer periphery of the transverse bar (8), as shown in FIGS. 1 to 5, on both sides of the cutting body (11),
Positioning stopper (21) as a regulating means (21
') is installed. This positioning stopper (21
) (21) is a transverse bar (8) as shown in FIG.
) is formed into a cylindrical shape so as to be slidably fitted to the outer periphery of the cross bar (8), and is fixed at a predetermined position of the transverse bar (8) by screwing the screw (22) from the outer periphery. being done. In other words, this positioning stopper (21)
(21) are fixed at appropriate positions on both sides of the slider (12) (thereby, the driving range of the cutting body (11) is restricted to the range between the positioning stops (21) and (21). be.

Now, to explain the support structure of the cutting body (11) and the boss (13), that is, the copy cutting mechanism, as shown in FIG. 6, the boss (13) has a through hole (
23) is formed, and a substantially central portion of the cutting body (11) is fitted into this through hole (23). and the cutting body (
There are upper collars (24) on both sides of the mating part of 11).
A coil spring (28) is interposed between the lower collar (25) and the boss (13) to attach the cutting body (11) downward. I'm trying to strengthen myself. In addition, the upper color (24
) is for preventing the cutting body (11) from being pulled out downward due to the biasing force of the coil spring (28). On the other hand, near the tip of the cutting body (11) is a workpiece sliding body (29) made of a material such as synthetic resin, polyethylene, or nylon.
is installed. The workpiece sliding body (29) has its proximal end fixed to the cutting body (11), and its distal end can slide on the cutting surface of the workpiece (3). Note that the length of the cutting edge of the cutting body (11) protruding downward from the lower surface of the workpiece sliding body (29) defines the cutting depth.

Next, the operating state of the grooving machine with the above configuration will be explained.

Vertical grooves (30) of the workpiece (3)...the number of cutting units (7a) corresponding to the number of band-shaped unit plate parts appearing between them.
- (7d) are installed on the fixed rails (6) (6). In this case, each cutting unit (7a) to (7d) is sequentially placed on the end of the rail support frame (2) (2), and then the rail sliding member (9) (9) is placed on the fixed rail (6). )(6
). Next, the work support stand (4)
Each cutting unit (7a) to (7d) moves to a predetermined position in the vertical direction where a horizontal groove is to be cut on the workpiece (3) installed in the
is moved and displaced, and the screw (10) is operated at that position to fix it to the fixed rail (6) (6). At the same time, in each cutting unit (7a) to (7d), the positions of the positioning stoppers (21) (21) on the transverse bar (8) are adjusted, the screws (22) are operated and fixed, and the cutting body ( 11)
to set the driving range. For example, when cutting a horizontal groove in the second band-shaped unit plate from the top in FIG. The positions of the positioning stoppers (21) and (21) are adjusted so that (11) moves. In order to chamfer the edges of the workpiece (3), a special tool is constructed by connecting two cutting bodies (11) (11) to each other with a connecting member (31) on a transverse bar (8). The cutting unit (7e) (7f') is connected to the fixed rail (6
) (6). Next, operate the solenoid valve (■9) so that the cutting body (11) is positioned at one of the longitudinal grooves, and move the slider (12) to one positioning stopper (21).
Initialize it so that it is in contact with the

After rotating the cutting body (11), the cylinder mechanisms (5) and (5) are driven to raise the workpiece (3) so that the cutting surface of the workpiece (3) hits the lower part of the upper surface guide (14). make contact with them. At this time, the cutting edge of the cutting body (11) will be located within one of the vertical grooves. Next, the solenoid valve (19
) to drive the cutting body (11) on the transverse bar (8) towards the other positioning stop (21). Thereafter, the slider (12) comes into contact with the positioning stopper (21), and the progress of cutting the lateral groove is stopped. At this time, the cutting body (11) is located in the other vertical groove. Then, the cylinder mechanism (5) (5) is operated to lower the workpiece (3) and take it out, then a new workpiece is installed, and the same operation as described above is repeated.

During the above-mentioned horizontal groove cutting, the cutting body (11) behaves as follows. That is, the workpiece sliding body (29) in contact with the workpiece (3) moves in the vertical direction following the surface shape of the workpiece (3). In conjunction with this, the cutting body (11) also moves in the vertical direction, and as a result, the cutting body (11) is driven to follow the surface shape of the workpiece (3). Therefore, the work (
3) Even if the surface of the cutting body (11) has some degree of deflection or is uneven, it will behave in accordance with the shape, and the distance relationship between the cutting body (11) and the workpiece (3) will remain constant. It will be preserved.

Here, when the type of workpiece (3) is changed and horizontal groove cutting is to be performed on a workpiece with a different width of the band-shaped unit plate portion, the cutting units (7a) to (7r) are moved as appropriate to the fixed rails (6) (6) and (7r).
) on the positioning stopper (21
) The position of (21) on the transverse bar (8) may be adjusted so that the cutting body (11) is driven in accordance with the width of the band-shaped unit plate portion of the workpiece. In this case, each cutting unit (
Since 7a) to (7d) do not interfere with each other in the lateral direction, it is possible to cut the lateral grooves even on narrow strip-shaped unit plates with narrow intervals between the vertical grooves (30). can be carried out.

In addition, when cutting horizontal grooves on a workpiece (3) with a different number of vertical grooves (30), that is, the number of band-shaped unit plate parts (for example, five band-shaped unit plate parts), Install the separately prepared cutting unit (7) onto the fixed rails (6) (6).
The construction site will be added to the building.

As described above, in the above embodiment, by appropriately resetting the drive range of the cutting body (11) using the positioning stoppers (21) (21), the length of the lateral groove to be cut and the position of the lateral groove in the lateral direction can be adjusted. can easily respond to changes. In addition, cutting units (7a) to (7d)
They do not interfere with each other in the lateral direction, and therefore the cutting body (11)... can move over the entire range on the transverse bar (8), so by making appropriate restrictions within that range, the cutting body (11) can be moved over the entire range. It is possible to cut horizontal grooves with extremely short lengths. Moreover, if the number of vertical grooves is changed, especially increased, a cutting unit may be added to the fixed rail (6) (6) 1. : It is possible to easily accommodate this by constructing a bridge. Further, since the rodless cylinder (1B) serving as the driving means also serves as the transverse bar (8), the grooved structure has the effect of making the entire processing machine compact. Furthermore, since the cutting body (11) moves in accordance with the shape of the surface to be cut of the workpiece (3), the depth and width of the lateral groove to be cut can be made constant.

11 to 13 show other embodiments of the invention. In this embodiment, the copy cutting mechanism is configured as follows. That is, as shown in FIG. 13, the upper end of the L-shaped support member (35) is connected to the slider (
12), and a pair of left and right guide rods (3B) (
3B) is erected. As shown in FIG. 12, a T-shaped boss (37) is slidably fitted over both guide rods (3B) (3B), and a T-shaped boss (37) is fitted over both guide rods (3B).
B) Spring holder (3g) at the top end of (3B)
(38) is installed, and the spring holder (38) (38)
A spring (39) (39) is interposed between the boss (37) and the boss (37). A through hole (40) is formed in the axial center of the boss (37), and the cutting body (11) is fitted and fixed in this through hole (40). Furthermore, the boss (3
A workpiece sliding body (41) is fixed to the lower end portion of 7). In other words, when the workpiece sliding body (41) receives an upward force depending on the shape of the cutting surface of the workpiece (3), the boss (37)
) The cover springs (39) rise against the biasing force of the springs (39), thereby maintaining a constant distance relationship between the cutting body (11) and the workpiece (3). In addition, in this embodiment, a fixed rail (42) having a circular cross section is further employed. In addition, an L-shaped support member (
35) from rotating around the transverse bar (8), a guide rod (44) is installed between the rail sliding members (43) as shown in FIG. As shown, a slide member (45) that fits around the outer circumference of the guide rod (44) is attached to the support member (35). In this embodiment, the same parts as in the above embodiment are given the same reference numerals, and their explanations are omitted. Also in this embodiment, it is possible to achieve the same effects as in the above embodiment.

In the present invention, the cutting body (11) can be of various types, such as an air motor type or a high frequency motor type.

In addition to adopting the rodless cylinder (16) as described above as the driving means, a pneumatic or hydraulic cylinder may be attached to the transverse bar (8) to drive the cutting body (11). It is also possible to rotate the motor etc. using a chain feed mechanism, rack and pinion feed mechanism,
The cutting body (11
) may also be adopted.

Furthermore, as a regulating means, in addition to using the abutting type positioning stopper (21) (21) as described above,
It is also possible to integrate the driving means and the regulating means by using a limit switch or by using a stepping motor as the driving means.

Effects of the Invention As described above, the grooving according to claim (1) of the present invention can be performed in a processing machine by appropriately resetting the drive range of the cutting body using the regulating means to control the length and width of the lateral groove to be cut. It is possible to easily accommodate changes in the position of the lateral grooves in the direction. In addition, the cutting units do not interfere with each other in the lateral direction, so the cutting body can move over the entire range on the transverse bar, making it possible to cut horizontal grooves even if the length is very short. be. Furthermore, if the number of vertical grooves is changed, especially increased, this can be easily accommodated by adding a cutting unit and installing it on the fixed rail.

In addition, in the case of the groove according to claim (2), since the rodless cylinder serves as both the transverse part and the driving means in the processing machine, it does not require space, and therefore the groove allows the entire processing machine to be constructed compactly. It is possible to do so.

Furthermore, in the grooving according to claim (3), in a processing machine, the cutting body moves in accordance with the shape of the surface to be cut of the workpiece, so the depth and width of the lateral groove to be cut are kept constant. can do.
