[0001]

[Technical field to which the invention belongs]

 The present invention relates to a sawing machine, and more particularly to a sawing machine for cutting an object to be cut such as metal or wood with a band-shaped saw blade.

[0002]

[Prior art]

 Conventionally, a vertical band sawing machine has been known as a sawing machine. This includes a driving wheel driven by an electric motor, a driven wheel disposed above the driving wheel, an annular band saw wound around the outer peripheral surface to connect the driving wheel and the driven wheel, and a driving wheel. And a table arranged between the driven wheels, and the band saw is rotated by the rotation of the driving wheel, so that the band saw is continuously moved in the vertical direction with respect to the workpiece mounted on the table. Things.

[0003]

[Problems to be solved by the invention]

 However, in the conventional band sawing machine, the band saw penetrates a predetermined position of the table and does not move in the horizontal direction. Therefore, when cutting the object placed on the table, the object is cut. Had to be pressed against the saw blade of the band saw. That is, the operator had to cut while moving the object to be cut. In other words, since a manual feeding operation was required, the burden on the operator was large, and the number of work steps could not be reduced. In addition, the work involved in moving the object to be cut with respect to the rotating saw blade involved a great deal of mental burden on the operator.

In view of the above, an object of the present invention is to provide a sawing machine capable of automatically feeding an object to be cut with a simple configuration.

[0005]

[Means for Solving the Problems]

 The sawing machine according to the first aspect of the present invention includes a saw blade that moves in the vertical direction, a fixed base that is perpendicular to the moving direction of the saw blade, and a cutting plane that is laid on the upper surface of the fixed base and that is parallel to the cutting direction. A linear guide rail, a slide member slidable along the guide rail, a movable table attached to the guide rail via the slide member, and an object to be cut mounted on an upper surface; A wire guide member provided near one end of the guide rail, a wire connected to one end of the movable table and suspended through the wire guide member, and a wire attached to a lower end of the wire; A weight member for moving from the other end of the guide rail toward the one end.

Therefore, according to the sawing machine of the present invention, first, the operator holds the movable table fixed to the other end of the guide rail, and opposes the movable table, particularly the saw blade. The object to be cut is set at the site to be cut. When setting an object to be cut, it is desirable to fix the object to the movable table with a pin or an angle. When the fixed state of the movable table is released, one end of the movable table is pulled through the wire by the gravity of the weight member, and the movable table is moved to one end of the guide rail by sliding between the slide member and the guide rail. Move towards. That is, the movable table moves while pressing the object to be cut against the saw blade moving upward and downward. Thus, the object is cut by the saw blade.

A sawing machine according to a second aspect of the present invention is the sawing machine according to the first aspect, wherein a sliding resistance of the movable table with respect to the fixed base is changed, and a moving speed of the movable table by the weight member. And a speed adjusting member for adjusting the speed.

[0008] Therefore, according to the sawing machine of the invention of claim 2, in addition to the operation of the invention of claim 1, even if the weight of the weight member, that is, the tensile force of the movable table is the same, the speed adjusting member. By changing the sliding resistance of the movable table with respect to the fixed base, the moving speed of the movable table changes.

A sawing machine according to a third aspect of the present invention is the sawing machine according to any one of the first to second aspects, wherein the movable table comprises two movable plates arranged in parallel with a gap therebetween. And a connecting member for connecting the two movable plates, and the slide members are respectively provided near both ends of the bottom surface of each movable plate.

Therefore, according to the sawing machine of the invention of claim 3, in addition to the operation of the invention of claim 1 or 2, the saw blade is vertically inserted into the gap between the two movable plates constituting the movable table. By allowing the movable plate to move, the movable plate and the saw blade do not come into contact with each other. Also, since the two movable plates are connected by the connecting member, they move simultaneously as an integral part. Further, since the slide members are provided near both ends of each movable plate, each movable plate is supported in a stable state.

[0011]

[Embodiment of the invention]

 Hereinafter, a sawing machine according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG. 1 is a side view showing the configuration of the entire sawing machine, FIG. 2 is an enlarged side view showing a part of a table unit in the sawing machine, and FIGS. 3 to 5 are perspective views showing the configuration of the table unit. It is a figure and a front view.

The sawing machine 1 according to the present embodiment is a vertical band sawing machine. As shown in FIG. 1, a casing 2 having a substantially U-shaped side surface and a driving wheel 3 pivotally supported at a lower portion of the casing 2. And a driven wheel 4 supported on the upper part of the casing 2, an electric motor 5 for rotating the driven wheel 3, and wound around the outer periphery of the driven wheel 3 and the driven wheel 4 so as to connect the driven wheel 3 and the driven wheel 4. An annular band saw 7 is provided, and a table unit 9 for mounting an object H to be cut by the saw blade 6 (see FIG. 3) of the band saw 7 is provided. Since the configuration other than the table unit 9 is the same as that of the conventional band saw machine, detailed description is omitted here, and the table unit 9 will be specifically described below.

As shown in FIGS. 2 to 5, the table unit 9 includes a fixed base 10 fixed to the casing 2, a plurality of support members 11 attached to both side surfaces of the fixed base 10, and a fixed base 10. Four guide rails 12 laid on the upper surfaces of the table 10 and the support member 11, a slide member 13 slidable along the guide rails 12, and a movable member mounted on the guide rails 12 via the slide members 13. And a table 14. The table unit 9 includes, as means for moving the movable table 14, a guide roller 15 supported on one end of the guide rail 12, a wire 16 connected to one end of the movable table 14, and a wire 16. And a weight member 17 attached to a lower end of the weight member 16. Further, the table unit 9 includes a speed adjusting member 18 as means for adjusting the moving speed of the movable table 14.

More specifically, the fixing base 10 is a metal plate-shaped member, and is disposed such that the upper surface thereof is perpendicular to the moving direction (up and down direction) of the saw blade 6. In the vicinity of the center of the fixed base 10, a long hole (not shown) is formed for vertically passing the band saw 7 therethrough.

The support member 11 has a long support member 20 attached to the right side of the fixed base 10 and a short support member 21 attached to the left side of the fixed base 10. These support members 20 and 21 are for supporting the ends of the guide rails 12 protruding from both side surfaces of the fixed base 10, and are formed by angles having a substantially L-shaped cross section. If the length of the fixed base 10 is equal to or longer than the length of the guide rail 12, the support member 11 becomes unnecessary. However, since the fixed base 10 of the present embodiment uses the table in the conventional apparatus as it is, the fixed base 10 is not suitable for the length of the guide rail 12, and therefore, the length required by the support member 11 is required. Is assured.

The guide rail 12 is a linear guide member, and has a recess 23 continuously formed in the front and back surfaces in the longitudinal direction. A stopper 24 for closing one end of the recess 23 is provided on the right end surface of the guide rail 12. The stopper 24 prevents the slide member 13 from coming off the guide rail 12, thereby restricting the movement of the movable table 14. As shown in FIG. 2, the guide rail 12 is attached to the fixed base 10 by screws 19.

The slide member 13 has a substantially U-shaped cross section, and a convex portion 25 that fits into the concave portion 23 of the guide rail 12 is formed on an inner surface thereof. Note that the guide rail 12 and the slide member 13 are commercially available components, and a plurality of small balls are interposed between the concave portion 23 and the convex portion 25 to reduce sliding resistance.

The movable table 14 has a first movable plate 27 and a second movable plate 28 juxtaposed with a gap 30 therebetween, and a connecting member 29 for connecting the two movable plates 27, 28. ing. Each of the movable plates 27 and 28 is a rectangular plate-like member, and a plurality of slide members 13 are attached by screws 26 near both ends of the bottom surface so as to correspond to each guide rail 12. . The connecting member 29 is provided with a locking ring 31 for connecting the wire 16.

The guide roller 15 is a disk-shaped member having a depression (not shown) formed on the outer peripheral surface, and is rotatably supported by a stopper 24. The wire 16 connected to the locking ring 31 is hung over the recess of the guide roller 15 and hangs down from the guide roller 15.

The speed adjusting member 18 includes a holding plate 32 hanging down from a front surface 28 a of the second movable plate 28, and a thumb screw 33 screwed to a lower portion of the holding plate 32. According to this, by rotating the thumb screw 33, the degree of pressure contact between the tip of the thumb screw 33 and the front surface 10 a of the fixed base 10 can be changed by the propulsive force. That is, the sliding resistance of the movable table 14 with respect to the fixed base 10 can be changed by operating the thumb screw 33. Since the sliding resistance increases as the amount of tightening of the thumb screw 33 increases, the movable table 14 can be held in a fixed state by tightening the thumb screw 33.

Next, an operation of the sawing machine 1 of the present embodiment, particularly, a method of cutting the workpiece H will be described. First, the operator positions the movable table 14 on the other end side (left side) of the guide rail 12 and tightens the thumb screw 33 screwed to the speed adjusting member 18. As a result, the tip of the thumb screw 33 is strongly pressed against the front surface 10a of the fixed base 10, and the movable table 14 is fixed. Thereafter, the workpiece H is set on the movable table 14 so that the cutting portion of the workpiece H faces the saw blade 6 of the band saw 7 penetrating the movable table 14. When setting, it is fixed to the movable table 14 using a pin or an angle (not shown).

After that, when the thumb screw 33 is loosened to reduce the pressure contact state with the fixed base 10, one end of the movable table 14 is pulled via the wire 16 by the gravity of the weight member 17, and the slide member 13 and the guide rail The movable table 14 moves toward one end (right side) of the guide rail 12 by sliding with the guide rail 12. That is, the movable table 14 moves while pressing the workpiece H against the saw blade 6 moving in the vertical direction. As a result, the workpiece H is cut by the saw blade 6. At this time, since the band saw 7 is located in the gap 30, it does not come into contact with the movable table 14. The moving speed of the movable table 14 can be adjusted by changing the pressure contact state with the fixed base 10 by the hinge 33. Needless to say, the moving speed of the movable table 14 may be adjusted by preparing a plurality of weight members having different weights and exchanging the weight members attached to the wires 16.

As described above, in the sawing machine 1 according to the above-described embodiment, the workpiece H is automatically sent by the gravity of the weight member 17, so that there is no need for an operator to manually send the workpiece H. The number is greatly reduced. In addition, since the dangerous work is eliminated, the mental burden on the worker is reduced.

In the sawing machine 1 of the above embodiment, the moving speed of the movable table 14 can be adjusted by the thumb screw 33 even if the weight of the weight member 17, that is, the tensile force of the movable table 14 is the same. Therefore, the workpiece H can be cut at an appropriate speed without preparing a plurality of types of weight members.

Further, in the sawing machine 1 of the above embodiment, the movable table 14 can be stably supported by the slide member 13 and can be smoothly moved by the four guide rails 12. That is, even if the weight of the weight member 17 is relatively light, the movable table 14 on which the workpiece H is placed can be reliably moved.

As described above, the present invention has been described with reference to the preferred embodiments. However, the present invention is not limited to these embodiments, and as described below, within the scope not departing from the gist of the present invention. Various improvements and design changes are possible.

That is, in the sawing machine 1 of the above embodiment, the rotatable guide roller 15 is shown as a wire guide member, but a member fixedly attached may be used. However, by rotating as in the present embodiment, the resistance of the wire 16 can be reduced, and the tensile force of the movable table 14 can be increased. Further, in the sawing machine 1 of the above embodiment, the guide roller 15 is supported by the stopper 24, but the guide roller 15 may be supported by the guide rail 12 or the long support member 20.

In the sawing machine 1 of the above embodiment, the stopper 24 is provided on the same axis line of the guide rail 12 and the slide member 13 is brought into contact. However, the stopper is provided independently and the stopper The movement of the movable table 14 may be restricted by making contact.

Furthermore, in the sawing machine 1 of the above-described embodiment, the one mounted on the support member 11 at both ends of the fixed base 10 is shown, but the length of the fixed base 10 is increased so that the support member 11 is omitted. No problem. By doing so, the number of parts is reduced, and assembly is facilitated.
