Description

  The present invention relates to a flat plate punching device for punching by pressing a plate-like member such as a corrugated cardboard sheet, cardboard, or film.

  Conventionally, punched materials such as corrugated board sheets supplied in a stacked form to the punched material supply unit are intermittently supplied one by one to the conveying means, and after pressing a predetermined die on the supplied punched material, the product As a flat plate punching device for punching a part, as shown in Patent Document 1, a press part that presses a predetermined die onto a punched material, and a product part and a gripper margin are left from the pressed punched material. Stripping part that removes the product part, knock-off part that separates the product part from the gripper margin, delivery part that accommodates the product part separated by the knock-off part, and material to be punched are intermittently applied to the pressing part, stripping part, and delivery part In general, there is known one having a conveying means for sequentially conveying.

In the above general flat plate punching apparatus, the position of the punched material from the press to the delivery unit is determined when the punched material supply unit transfers the material to the conveying means.
Therefore, it is also important to accurately place the punched material on a predetermined position of the punched material supply unit.
On the other hand, in order to improve productivity, when trying to increase the conveying speed of the conveying device, the speed at which the punching material such as corrugated cardboard sheets supplied in a laminated form is intermittently supplied one by one by the conveying means is markedly increased. It must be made faster, and misalignment is likely to occur during transfer from the punched material supply unit to the conveying means.

If the supply position from the punched material supply unit to the conveying means is deviated, a defective product is generated.
In particular, the material to be punched is pre-designed with letters, designs, etc., and if the design and the position to be punched deviate even a little, it becomes a defective product, and the incidence of the defective product increases. There was a problem that productivity was lowered. For this reason, the current situation is that the processing speed (conveyance speed) of the flat plate punching apparatus cannot be sufficiently increased.

The conveying means 10 is such that the punched material 2 stacked on the feeder section 3 is pulled out one by one to the set plate 15 by the conveyor 14 so that the punched material 2 is sent out, and the punched material whose position is corrected by a supply position correcting means 18 described later. 2, the gripper margin is held by the holding unit 11, and the endless roller chain 12 is intermittently rotated so as to sequentially pass through the press unit 4, the stripping unit 5, and the delivery unit 9 while holding the punched material 2. I try to drive it.

  The press unit 4, the stripping unit 5, and the delivery unit 9 are sequentially arranged at equal intervals, and are held by the holding unit 11 when the roller chain 12 of the conveying unit 10 is driven to rotate intermittently. Further, the holding portions 11 are provided on the roller chain 12 at equal intervals so that the plurality of punched materials 2 are simultaneously stopped at the fixed positions of the press portion 4, the stripping portion 5 and the delivery portion 9.

A press unit 4 is provided on the discharge side of the feeder unit 3 to press a predetermined die against the punched material 2. The press unit 4 is fixed above the punched material 20 so as to sandwich the punched material 20 therebetween. The fixed plate 6 on which the mold is mounted and the press plate 17 which is positioned below the punched material 2 and moves up and down with respect to the fixed plate 16 are configured.
In this press part 4, the die is pressed so as to separate the product part, the gripper margin and the non-product part into the punched material 2.

A stripping section 5 is provided on the downstream side of the press section 4. In the stripping section 5, only the non-product portion is removed from the pressed punched material 2 leaving the product portion and the gripper margin.
And between the feeder part 2 and a conveyance means, the position correction | amendment means 18 which correct | amends the position of the to-be-punched material 2 sent to the conveyance means 10 from the feeder part 2 is provided.
As shown in FIGS. 3 to 6, the position correction means 18 is provided with guide beams 20 whose both ends are supported by support plates 19 in the width direction perpendicular to the traveling direction of the punched material 2 of the flat plate punching device 1, Position correction tools 21 (described later) are provided on both ends of the guide beam 20 so as to be slidable in the left-right direction in FIG.

The position corrector 21 is fitted to a screw shaft 24 driven by a sheet width setting motor 23 via a gear transmission mechanism 22 to slide the paper width setting slider 25 to the left and right to thereby slide the paper width setting slider. A slider 27 in which a contact tool (plate-like member) 26 made of a metal plate material is erected on the upper surface of the moving element 25 is brought into contact with and separated from the side edge portion of the punched material 2 by a cam mechanism 28. It is designed to slide.
The cam mechanism 28 pivotally supports a rotating shaft 29 between the support plates 19, 19, and a side cam plate 30 that can slide on the rotating shaft 29 by a spline or a key groove and cannot rotate relatively. The roller 31 suspended from the slider 27 provided with the abutment tool 26 is brought into contact with the cam surface 32 of the side cam plate 30 by an abutment biasing spring 32 (see FIG. 3).

A sprocket 32 is attached to the central portion of the rotating shaft 29, and the sprocket 33 is connected to a driving portion (both not shown) of the conveying means 10 by a chain so that the conveying means 10 is intermittently driven. It is connected so as to be interlocked, that is, interlocked with the intermittent feed drive from the feeder section 32 to the roller chain 12 of the conveying means 10.
Reference numeral 33 in the figure denotes a back pusher that is fed from the feeder section 2 to the set plate 15 side by the feed conveyor 14 and pushes the punched material 2 away from the feed conveyor 14 to the set plate 15 side.

A procedure for using the flat plate punching device 1 according to the present invention configured as described above will be described below.
First, the material to be punched 2 having a design such as a character or a pattern is laminated on the surface of a printed cardboard sheet or the like and placed on the feeder unit 3.

Next, the flat plate punching device 1 is activated, and the punched material 2 at the lowermost end set in the feeder portion 3 in a laminated form is sucked and sequentially sent to the transport means 10 by the delivery conveyor 14. .

As shown in FIG. 6, the punched material 2 is sent to the conveying means 10 by the delivery conveyor 14, pushed out by the back pusher 33 and pushed to the position held by the conveying means 10, and the cam mechanism of the position correction tool 21. The 28 rotation shafts 29 are rotationally driven.
Then, immediately before the punched material 2 is held by the conveying means 10, the side cam plate 30 is rotated by the rotating shaft 29 rotating the cam mechanism 28, and the roller 31 is moved inward by the cam surface 32. .
When the roller 31 is moved inward, the contact tool 26 slides inward, and if the punched material 2 is misaligned, it is corrected by pushing it to the correct position.

Thus, since the punched material 2 is held by the conveying means 10 immediately after the correction, the subsequent processes from punching to punching and separation can be performed accurately, such as characters and designs shown on the surface. The punching process can be performed accurately according to the design.
Thereby, it is possible to prevent as much as possible the occurrence rate of defective products due to the punching process at the shifted position.
Even while the position is being corrected by being placed on the set plate 15, a part of the succeeding punched member 2 is placed above the preceding punched member 2 because the delivery conveyor 14 is continuously driven. For this reason, the position of the preceding punched member 2 is likely to be shifted, but even in such a case, the punching material 2 is held by the conveying means 10 immediately after being corrected by the position correction tool 21, It is prevented that it shifts.

Further, by continuously driving the delivery conveyor 14 as described above, it has become possible to supply a part of the subsequent punched member 2 so as to overlap the preceding punched member 2. Therefore, it is not necessary to intermittently drive the delivery conveyor 14, and the feeding speed of the delivery conveyor 14 is significantly lower than the speed in the case of intermittent feeding while feeding the punched member 2 one by one. Can be.
In other words, even if the conveying speed of the conveying means 10 is increased, the driving speed of the delivery conveyor 14 can be made to correspond to this, and the productivity can be improved.

As in the above embodiment, the cam is not limited to the sprocket 33 connected to the driving unit of the conveying unit 10 and interlocked with the intermittent driving of the conveying unit 10, and the cam is driven by the motor that is timed directly from the control device. The rotating shaft 29 of the mechanism 28 may be rotated, or the side cam plate 30 can be rotated.
Further, in place of the cam mechanism 28, the contact tool 26 can be driven by an air cylinder or solenoid in conjunction with intermittent conveyance of the punched material 2.
