Along with this, the work a is transferred in the Y-axis direction,
It can be scraped out of the cutting table 1.

On the other hand, the unloader device B is provided in a continuous manner with the cutting device body A in the vicinity of the end of the cutting device body A on the work scraping side. The unloader device B has a pair of elevating frames 5 facing each other with a required space (for example, a space slightly wider than the lateral width of the work a), and the elevating frame 5 is supported by the lifter 6 to support the work a. It extends horizontally in the scraping direction.

The lifter 6 is provided with four ball screws which are respectively provided upright at four corners of a work stock space C which is continuously provided at an end of the cutting device body A on the work scraping side.
61, and each of these ball screws 61 has a ball nut 62.
Is screwed.

A sprocket is provided on the outer periphery of each ball nut 62.
63 is fitted and fixedly connected to the ball nut 62 by a screw 64. The chain 64 is wound around these four sprockets 63 and any one sprocket is
The motor 63 is rotated by a motor 65 (hereinafter referred to as a lifting motor).

On the upper part of the sprocket 63, there is an elevating cylinder 66 fitted on a ball screw 61 so as to be vertically slidable.
The bracket 51 provided on the elevating frame 5 is connected to the frame attachment attachment 69 which is rotatably engaged with the small diameter portion 66b formed on the upper part of the elevating cylinder 66 via the stepped portion 66a via the bearing 68. It is fixed.

When a predetermined sprocket 63 is driven by a motor to rotate the lifter 6, all the sprockets 63 are simultaneously rotated through a chain 64, and a ball nut 62 connected to these sprockets 63 is rotated. Therefore, the ball nut 62 moves up and down according to the rotation direction, and by moving the ball nut 62 up and down, the sprocket 63 and the elevating cylinder 66 that are sequentially connected to the ball nut 62 also elevate, and the attachment 69 fitted in the elevating cylinder 66 is attached. The attached lifting frame 5 is moved up and down.

Rotating shafts 52 are mounted on both ends of the elevating frame 5 in its extension direction (hereinafter referred to as front-rear direction), and one rotating shaft 52 is rotationally driven by a motor 53 (hereinafter referred to as a plate driving motor). It has become so. A pair of left and right sprockets 54 is provided on each rotary shaft 52, a chain 55 is wound around the sprockets 54 on the same left and right sides, and the work receiving plate 7 is extended across the left and right chains 55, 55. It is provided.

The work receiving plate 7 is constructed by arranging a large number of plate units 71 having a narrow width side by side in a saw-like shape. Both ends in the length direction of each plate unit 71 are left and right chains 55, 55.
It is fixed via attachment 72.

The work mounting plate 7 is a chain.
It is provided on almost half of the circumference of 55, and the inner surface of the chain with respect to the running track is the work receiving surface 7a. Thus, the work receiving plate 7 travels with the chain 55 as the sprocket 54 is rotated by the motor.

In such an unloader device B, when the lifting frame 5 is at the uppermost position and the work receiving surface 7a of the work receiving plate 7 is continuous with the cutting table 1 of the cutting device main body 7, the unloader device B is almost the same as the table 1. It is located upwards on the same height plane.

Therefore, when the cutting of the corrugated cardboard a by the cutting device body A is completed and the work transfer device 2 scrapes the work a from the cutting table 1, the work a moves onto the work receiving plate 7 of the unloader device B. To do.

The unloader device B is equipped with the device B.
A stopper 56 for fixing the position of the work on the work receiving plate by hitting the front end of the work a transferred to is provided between the elevating frames 5 and 5.

A stock carriage D is provided in a work stock space C surrounded by a line connecting the four ball screws 61 of the lifter 6.

In this state, the lifting motor is driven to lower the lifting frame to a height position where the work receiving plate is close to the upper surface of the work stock carriage D or the upper surface of the work a'which is already stocked on the carriage D. Then, when the work receiving plate driving motor 53 is driven, the work receiving plate 7 inverts upward and travels around so that the work a supported by the plate 7 is placed on the upper surface of the carriage D or already the carriage D. The work a ′ stocked on D falls on the upper surface and is stocked.

That is, since the tip of the work a on the work receiving plate 7 is in contact with the stopper 56, the plate driving motor can be operated while the work a is on the plate 7.
Even if 53 is driven to move the work receiving plate 7,
The work a cannot be moved together with the plate 7, and the plate 7 is pulled out from the lower surface of the work a. The work a is gradually pulled from the end where the support is removed by the pulling out of the plate 7 to the upper surface of the carriage D or already the carriage D. The work a ′ that has been stocked above falls down so as to slide down.

Therefore, the plate driving motor 53, the sprocket 54, the chain 55, etc. constitute plate removing means for removing the plate from under the work a.

Since the work receiving plate 7 is close to the upper surface of the dolly D or the upper surface of the work a'which has already been stocked on the dolly D, the work a is dropped at a short distance and gradually from the end. The cutouts will not come off the cardboard and fall apart.

The driving of the lifting motor 65 and the plate driving motor 53 is controlled by a controller (not shown) based on the detection of the sensors 8 and 9, respectively.

That is, the unloader device B requires the first sensor 8 for confirming whether the work a transferred from the cutting ink device main body A is moved to a predetermined position of the work receiving plate 7 and the elevating frame 6. A second sensor 9 for confirming whether or not it has descended to a different height position is provided, and the control unit outputs the detection signal of the first sensor 8 to drive the lifting motor 65 in the direction of lowering the lifting frame 5.
The plate driving motor 63 is rotationally driven, and the plate driving motor 63 is rotationally driven in the direction in which the work receiving plate 7 is inverted upward by the detection signal output of the second sensor 9.

The first and second sensors 8 and 9 each comprise a beam sensor, and the first sensor 8 outputs a detection signal when it detects the tip of the work a at the position of the stopper 56,
The second sensor 9 is provided in the lower part of the elevating frame and outputs a detection signal when detecting the upper surface of the dolly D or the uppermost work a'stocked on the dolly D.

In the embodiment described above, the work receiving plate is made flexible, and it is pulled out from the bottom of the work by connecting it to an endless chain driven by a motor, running it upside down and turning around. However, if the work receiving plate is rolled into one side like a shutter door, or if there is room in the factory, the work receiving plate will be a flat plate without flexibility and be pulled out horizontally as it is. It is also possible to have such a configuration. In the figure, E is a stocker for supply.

[0030]

The present invention is configured as described above, and has the following effects. (1). The work scraped out from the main body of the cutting device is received by the receiving plate, and the whole plate is moved to a height close to the upper surface of the work stock carriage or the work already stocked on the carriage, and its position The plate can be pulled out from the bottom surface of the work with the work piece, and the work piece can be gradually dropped and moved from the end to the top surface of the stock base or the top surface of the already stocked work piece at a close distance. Even if it is not moved to, it is possible to stack it on a dolly or the like in order and stock it in order, and there is no fear that the cut out parts will come apart from the work and fall apart. (2). Since the lifting and lowering of the work by the lifter and the withdrawal of the work receiving plate from the work can be controlled based on the position detection by the sensor,
The work can be easily taken out and stocked after the cutting is completed, and labor can be saved.
