Description

[Detailed description of the invention] The present invention relates to a sizing ruler, and more specifically, a multi-stage sizing ruler installed on the side of a plate processing machine, such as a shearing machine, bending machine, or press brake, that supplies plate materials. It's about rulers.

Conventionally, the sizing ruler installed on the sheet material supply side used in the above-mentioned sheet processing machines is called a front gauge, and the sheet material to be supplied is manually fed past the processing line, and then pulled. The tail end of the board is positioned by returning it and pressing it against sizing rulers set at two locations on the left and right. For this purpose, the left and right sizing rulers have, for example, a pure triangular shape with a long side and a short side, or a bell crank shape, and the long side is placed as far away as possible from the rotation axis provided near the pure corner. Because the center of gravity is located and the short side is facing the processing line,
When pushing the plate material on the material feeding table toward the processing line, the short side is pushed by the material and due to the above rotation, it sinks lower than the surface of the material feeding table to allow the material to enter, and after passing the material, Because the center of gravity is on the long side, the short side of the sizing ruler protrudes above the material feeding table surface again, and when the board is pulled back as described above, the tail end of the board comes into contact with the short side of the sizing ruler. The position is determined by

Conventionally, in the rotating sizing ruler as described above, a pair of rulers were manually or electrically positioned and fixed in two grooves provided on the left and right sides of a material feeding table. Therefore, in high-mix, low-volume production, the position of the ruler must be changed frequently, which inevitably reduces work efficiency.

The present invention has been made to overcome the above-mentioned drawbacks, and preferred embodiments thereof will be described in detail with reference to the drawings.

In FIGS. 1 and 2, a pair of left and right sizing rulers 1 are attached to a sliding member 3 so that their positions can be adjusted slightly. The position can be changed by moving with respect to the processing line 9 numerically controlled by a drive mechanism 7, which will be described later.
Further, the groove-shaped guide support 5 is manually moved in the left-right direction parallel to the processing line 9 by a bolt 15 that engages with a T-shaped groove 13 provided on the front surface of the table 11 of the processing machine at its front end near the processing line 9. It is fixable and has a supporting leg 17 near the front end (on the right side in Figure 2).
In the illustrated example, three pairs of sizing rulers 1 are attached, and the rulers at the front and rear ends can be inserted from both sides to adjust and fix the position slightly, and the center ruler is inserted into the elongated hole without a flange. The rulers are moved to the part where the flange is located, adjusted slightly, and then fixed. In the fixed state, the abutting portions of the left ends of each pair of rulers in FIG. 1 are naturally parallel to the processing line 9. Therefore, in response to a command from the operation box 19, the drive mechanism 7 is driven to move the sliding member 3 not only into the groove-shaped guide support but also to the position shown by the imaginary line in FIGS. 1 and 2. It can be moved numerically.

3, 4, 5, and 6 are diagrams for explaining a drive mechanism for moving the sliding member 3 toward and away from the processing line 9 by numerical control.

The left and right grooved guide supports 5 are equipped with a fixed base plate 21 at the end on the side of the processing line 9, and an electric motor 2 with a brake having a rotating shaft in the horizontal direction is provided between the base plate 21 and the front surface of the processing machine.
3 is fixed.

The rotation of the shaft of the electric motor 23 with a brake is transmitted to one lead screw 31 via the reducer 25, the coupling 27, and the bevel gear box 29, and as shown in FIG. , the rotation is transmitted to other lead screws via the spline connector 35, the coupling 37, and the bevel gear box 39 again.
The rotary shaft of an encoder 43 is coupled to the rightmost end in FIG. Therefore, even if the position of the fixed board 21 is changed by moving the bolts 15 within the T-shaped groove 13 provided on the front surface of the table 11 of the processing machine, the expansion and contraction of the spline connector 35 will cause the two parallel The lead screws rotate in the same direction in synchronization.

As shown in FIG. 6, the groove-shaped guide support 5 described above consists of two square pipes 45,
In addition to the two square pipes being joined at the top and the right end in FIG. There is.

Therefore, as shown in FIG. 6, if the connecting member 49 is attached below the sliding member 3, the lower end tubular portion 51 is provided, and the nut member 53 is provided to engage with the lead screw 31. As shown in FIG. 4, the sliding member 3 moves between the front and rear bearing portions 47, and its position can be changed numerically by the electric motor 23. Further, micro switches 55 shown as an example are provided at appropriate locations and engage with a dog 57 provided at the lower end of the connecting member 51 to detect, for example, the forward end and the backward end and prevent overrun.

As can be understood from the description of the embodiments above, the gist of the present invention is to extend a plurality of guide supports connected to the front surface of the table of a processing machine in a direction perpendicular to the processing line of the processing machine. and each guide abutment is provided so that its position can be freely adjusted in the direction along the processing line, and the rear end of each sliding member slidably supported on each guide abutment is positioned close to the processing line. A sizing ruler is provided at multiple locations near the front and rear ends of each sliding member and at suitable locations in the middle of each sliding member. The drive device is attached to the plate material to be machined, and the drive device and each sliding member are interlocked and connected to simultaneously perform movement and positioning of each sliding member using numerical control. The position of the guide support can be adjusted according to the width of the plate, and the plate can be supported without bending or the like. Further, since the rear end of each sliding member is movable to a position close to the processing line, accurate positioning can be performed even when the plate material is short. Furthermore, since the plurality of sliding members are interlocked and connected to a single drive device and are moved and positioned simultaneously using numerical control, the configuration is simplified and the efficiency of positioning the plate material is improved. . Note that by providing the end portion of the sliding member so as to be able to protrude largely from the guide support, the plate material can be positioned over a large range that is longer than the length of the guide support, even if the overall configuration is small. Further, since the movement and positioning of the sliding member can be performed numerically controlled, the movement and positioning can be performed quickly and easily, improving work efficiency.

Note that the present invention is not limited to the above-described embodiments, but can be implemented in other embodiments by making appropriate changes.

Note that this invention can be implemented in other forms than the above-mentioned embodiments by making appropriate design changes. For example, it is possible to attach a magnet or a vacuum device to each sliding member to attract the plate material, and it is also possible to use a contact detection device such as a switch device that detects the contact of the plate material with each sizing ruler. It is also possible to adopt a configuration in which a device is provided. With the above configuration, it is possible to move the sliding member and the plate material integrally, and it is also possible to perform processing after confirming that the plate material is in contact with each sizing ruler. It is what it is. That is, it is also possible to add various functions to the design if necessary.
