Is cut off from the sides of the workpiece and the work is finished to a predetermined size.

By the way, the second transfer table of the sizer described above is provided with an adjustable work stopper for fixing the transferred work at a predetermined position on the transfer table. This work stopper is usually configured to be slid by a drive mechanism using a servo motor, and is slid on the basis of a preset program to be positioned and fixed at a predetermined position on the carrying table. It was supposed to be.

[0006]

However, the work stopper positioning structure in the above-described conventional sizer device is a structure in which the servo motor is slid and adjusted using the drive source, and the servo motor is relatively broken. However, in this case, the sizer device itself cannot be used until the failure of the servomotor is repaired, and the device cannot be used for one week or two weeks or more. In addition, when setting the dimension of the work newly,
It had the drawback that it had to be changed from the program and could not be dealt with easily.

The present invention has been made in view of the above circumstances. Even if the moving mechanism of the work stopper is out of order, the present invention can easily cope with the work stopper and the work stopper in the sizer device. An object is to provide a positioning structure.

[0008]

According to the present invention, in order to achieve the above object, a work stopper is slidably provided on a carrying table, and the work stopper is provided in accordance with the size of the work to be cut. The sizer is positioned and fixed at a predetermined upper position, the workpiece conveyed on the conveyor table is relatively pressed against the workpiece stopper to be positioned, and in this state, the opposite side end portion of the workpiece is cut off. In the above, the work stopper is slidably provided on a stopper support base provided on the carrying table, and a plurality of holes are formed at predetermined intervals along the slide direction of the work stopper on the mutually opposing surfaces of the work stopper and the stopper support base. Every other time, the distance between the holes is different depending on the distance between the holes on the stopper side and the distance on the stopper support side. Wherein one of the workpiece stopper side of the hole of one of said stopper support base side of the hole is selected, respectively, are configured to perform positioning of the workpiece stopper by inserting a pin in a state in which overlapping of the holes.

According to the work stopper positioning structure in the sizer device of the present invention, the work stopper is slid to the desired position, and at this time, one of the matching holes on the work stopper side and the corresponding hole on the stopper support base side. Insert the pin into one of. With such a positioning structure, even if the work stopper moving mechanism fails, it can be switched to the manual mode, and the problem that the sizer is stopped for one week or two weeks or more can be avoided.

Further, since the distance between the holes on the work stopper side and the distance between the holes on the work support side are made different, a combination of these holes is arbitrarily selected and a pin is inserted, so-called vernier. Since the structure is a formula, it is possible to finely adjust the movement amount of the work stopper.

May be positioned by an appropriate adjusting means, and the work W may be moved by a dedicated moving mechanism, and the end of the work W is abutted against the work stopper to position the work.

Further, this second sizer machine also has a fixing means 28 similar to that used in the first sizer machine for the work positioned by the ruler or the moving plate ( (Not shown), this may be omitted if necessary. Reference numeral 142 is a guide provided at the rear end of the ruler 120, which allows the work W transported on the transport table 7 to escape in the X ₂ direction.

Next, the operation of the sizer device will be described. A panel-shaped work W, in which face materials are bonded to both surfaces of a core material, is transferred by a pressing machine (not shown) on the transfer path 1 and transferred to the transfer table 6 of the first sizer machine 3 (FIG. 2, see FIG. 3).

On the transport table 6, the work W is transported by the transport rollers 10 in the forward direction, and when the rear end of the work W passes the rear end of the transport table 6, the effect is that the rear end of the transport table 6 is reached. Is detected by an optical sensor (not shown) provided in the
Reverse rotation for a very short time. As a result, the work W is stopped at a position where its rear end substantially coincides with the rear end of the transport table 6.

Then, the work W is positioned at a predetermined position on the carrying table 6 by the positioning means 26.

Specifically, the air cylinder is operated, and the first lateral end stopper 3 provided at the corner of the carrying table 6 is provided.
1 and the vertical end stopper 46 are arranged at a position projecting above the upper surface of the transfer table 6 so that the workpiece W on the transfer table 6 can be engaged with the cylinder 80. Then, the positioning pin 48 is in the extended state.

Almost at the same time, the pulse motor 7
0 is driven, and the motor base 66 supporting the lateral sizer blade 14 is moved in the Y ₂ direction via a power transmission system such as a chain. The movement of the motor base 66 is performed at a high speed in the initial state, but is performed at a low speed after the presence of the work W is detected by the optical sensor 72 provided on the side edge portion of the motor base 66. In addition, while the motor base 66 is moving in this way, it switches to a low speed,
The cylinder 82 is actuated and the second lateral end stopper 32 projects laterally from the motor base 66.

Along with the movement of the motor base 66, a motor (not shown) is driven to rotate the bolt member 38 in a predetermined direction, and the transfer ruler 30 is moved in the X ₁ direction in the drawing. At this time, the side end surface 30a of the transfer ruler 30 comes into contact with the side edge of the opposing work W, and moves the work W in the same direction. The front and rear end surfaces of the work W are brought into contact with the first and second lateral end portion stoppers 31, 32, whereby the workpiece W is laterally positioned.

The work W is generally sandwiched between 0 and 0, and in this state, the motor base 66 further moves in the Y ₂ direction. As a result, the positioning pin 48 in the projecting state pushes and moves the end of the work W, and brings the work W into contact with the vertical end stopper 46. As a result, the work W is positioned in the vertical direction.

Next, a clamp 40 which is the fixing means 28.
The workpiece W thus positioned is fixed at that position. Specifically, the air cylinders attached to the upper frames 52 and 54 are actuated to move the work W between the engaging portion attached to the tip of the descending piston rod and the end plate of the lower transport table frame 25. Insert it firmly. At this time, the rear end surface and the side end surface, which are the cut portions of the work W, slightly project outward from the edge surface of the table frame 25.

When the fixing of the work W is completed, the first lateral end stopper 31 and the vertical end stopper 46 are lowered, and the motor base 66 is slightly moved in the Y ₁ direction, and then the second lateral end stopper is moved. The end stopper 32 and the work positioning pin 48 retract backward.

Next, the motor base 5 is driven by the driving means.
0 is moved in the X ₁ direction, and the rear end surface of the work W is cut by the vertical sizer blade 13 attached to the upper part of the 0, and the motor base 66 on the other side is further moved in the Y ₂ direction at the same time. The lateral sizer blade 14 attached to the upper portion cuts the side end surface of the work W.

When the above cutting is completed, both sizers 1
Both 3 and 14 return to their original positions and stop.

After that, the motor (not shown) is driven to rotate the bolt member 38 in the opposite direction to the above, and the transfer ruler 3
0 is moved in the X ₂ direction. At this time, the work W is gripped by the clamp 40 attached to the transfer ruler 30 in advance. Therefore, the work W is moved in the X ₂ direction together with the transfer ruler 30 and the transfer table 6 is moved.
To the center position in the width direction (see FIG. 9).

Next, the carrying roller 1 of the carrying table 6
0 rotates in a predetermined direction to convey the work W forward.

Then, the workpiece W processed as described above.
Are transferred to the second sizer machine 4. Here, the rear end surface Wc, which is an unprocessed portion of the work W, and the other side end surface Wd are cut and processed.

That is, the work W is first conveyed by the conveying roller 1.
By 0, the carrying table 7 is carried to almost the center.
Next, the ruler 120 moves in the Y ₁ direction and the moving plate 122 moves in the X ₂ direction, and abuts on the front end surface Wa and the side end surface Wb of the work W, respectively.

Then, the ruler 120 and the moving plate 122 further move in the same direction to press and move the work W, and the rear end surface Wc and the side end surface Wd of the work W are the positions facing the cutter, respectively. The table 7 is made to project from the edge of the table 7. Then, in this state, the work W is fixed by a fixing means (not shown), and the vertical sizer blade 13
And those edges are cut by the horizontal sizer blade 14, respectively.

Here, when the ruler 120 or the moving plate 122 in the second sizer 4 pushes the work W to move it to a predetermined position on the carrying table 7, for example, the moving plate 122 The positioned pin 126 is lowered and the holes 120b, 1
22b, whereby the movable plate 122 is positioned in the vertical direction. Similarly, for the ruler 120, the ruler side and the stopper support base 140 that are overlapped are similarly formed.
By inserting the pin into the hole on the side, X of the ruler 120 concerned
Positioning is done in the ₁ and X ₂ directions.

At this time, the work W is measured in advance in the vertical and horizontal dimensions by the measuring means 100 in the first sizer machine 3, and therefore in the second sizer machine 4,
The positions of the ruler 120 and the moving plate 122 for positioning the work W are known in advance.

When the sizer processing is completed, the workpiece W is also conveyed by the clamp 40 attached to the ruler 120 when the ruler 120 is returned to its original position.
Is returned to the substantially central portion in the width direction, and then the conveyance roller 10 is driven to feed the processed work W forward (FIGS. 12 and 1).
3).

The sizer device of the present invention is not limited to that shown in the above-mentioned embodiment, but the specific components such as the shape, dimensions, work procedure, etc. of each member can be appropriately changed in practice.

For example, in the above embodiment, the transfer ruler 30 is used as the transfer means for transferring the work W in the lateral direction, and the ruler 30 is transferred by the screwing means of the bolt member 38 and the nut 36. However, the invention is not limited to this, and the work may be directly pressed by an air cylinder or a hydraulic cylinder.

[0079]

As described above, according to the sizer device of the present invention, the work stopper is slidably provided on the stopper support base provided on the carrying table, and the work stopper and the stopper support base are provided on the surfaces facing each other. A plurality of holes are provided at predetermined intervals along the slide direction of the work stopper, and the intervals between these holes are made different depending on the distance between the holes on the stopper side and the distance on the stopper support base side.
Moreover, one of the holes on the side of the work stopper and one of the holes on the side of the stopper support are respectively selected, and the pins are inserted in a state where these holes are overlapped with each other to position the work stopper. Even if the work stopper moving mechanism fails, it can be switched to the manual mode, and the sizer device can be prevented from being forced to stop for a long period of time.

Further, since the distance between the holes on the work stopper side and the distance between the holes on the work support side are made different, by arbitrarily selecting a combination of those holes and inserting a pin, It has excellent effects such as fine adjustment of the movement amount of the work stopper.
