Even if a part of the plate 1 is in a disturbed state so as to be aligned by the guide of the guide surface 173a in the ascending process.

Hereinafter, the operation of the sensing device 100 according to the present invention will be described with reference to the accompanying drawings.

First, the sensing device 100 is positioned on an upper portion of the paper sheet 1 in which a plurality of sheets are stacked on a lift (not shown).

At this time, by moving the vertical movement bracket 120 in the vertical direction by using the adjustment member 131, the distance between the uppermost layer of the laminated paper plate (1) and the rotating member 153 descending by the elevating rod 141. Set it.

That is, as shown in FIG. 9, the contact roller 157 of the rotating member 153 can set the pressure on the surface of the paper sheet 1.

The setting value according to the above setting is input to the control device (not shown), and the control device receives and calculates the setting value and the signal transmitted from the sensor 180 to lift and lift the paper sheet 1 laminated. .

When the vertical movement of the vertical movement bracket 120 is completed, the horizontal movement plate 110 is moved to the left side in the drawing of FIG. 9 while holding the handle 113 of the horizontal movement plate 110 to arrange the alignment bar 173. ) To push the rear surface of the laminated sheet of paper (1) to support it in an aligned state.

At this time, since the alignment bar 173 is lowered by the driving of the alignment cylinder 171 as shown in FIG. 9, one side of the alignment bar 173 pushes the rear surface of the paper plate 1 stacked.

Thereafter, the pressure unit 150 is lowered along with the lowering of the elevating rod 141 by the elevating cylinder 140.

The lowering of the lifting rod 141 proceeds until the contact roller 157 reaches the position of FIG. 9 in the direction of the arrow of the contact roller 157 while the contact roller 157 makes initial contact with the upper surface of the laminated paper sheet 1. do.

At this time, the rotating member 153 is rotated about the rotating protrusion 152 to make the progress of the contact roller 157, in this process the contact roller 157 by the rotation of the rotating member 153 paper plate material The upper surface of (1) is pressed.

At the same time, the elastic member 165 is contracted by the rotating member 153 rotating as shown in FIG. 9 to impart elasticity to the rotating member 153 so that the lowering pressure of the lifting rod 141 is directed to the upper surface of the paper plate 1. Prevent delivery.

In addition, the rotation bar 160 is interlocked with the rotation member 153 and sensed by the detection sensor 180 as shown in FIG. 9.

In this case, the detection sensor 180 transmits the detected signal to the control device, and the control device determines that the sheet of paper sheet 1 can be withdrawn and does not proceed with the lifting of the paper sheet 1 stacked on the lift. Do not.

Subsequently, when the paper sheet 1 laminated by the picker (not shown) is continuously drawn out one by one, the stack height of the paper sheet 1 due to the exhaustion of the paper sheet 1 gradually decreases.

In this process, the rotating member 153 is gradually rotated by the repelling force of the contracted elastic member 165 and the paper sheet 1 drawn out, and at any moment, the rotation member 153 is in a state as shown in FIG. 10.

At this time, since the rotation bar 160 also interlocks with the rotation member 153, the sensor 130 is out of the sensor 180 as shown in FIG. 10 at any moment.

In this case, the detection of the detection sensor 180 is cut off and at the same time, the control device places the uppermost layer of the laminated paper sheet 1 while driving the lift upward, as shown in FIG. 9.

In this process, the rotating member 153 rotates as shown in FIG. 9 and presses the upper surface of the paper plate 1 to the contact roller 157 by the contraction of the elastic member 165.

Since the above process is made by the sensor 180 for detecting the rotating bar 160 to rotate, the paper plate 1 stacked on the lift is repeatedly carried out until the exhaustion of all.

As described so far, the paper sheet stacking height sensing device of the present invention, when taking out the paper sheet laminated on the lift to form the paper sheet into a paper box, even if the thickness of the paper sheet to be formed is changed or set separately By detecting the height of the paper plate exhausted position in accordance with the withdrawal in response to the thickness of the various paper sheet without the process, the delay of the process due to the need to reset the sensing devices or reset the lifting height of the lift as in the conventional First of all, the setting is accurate, so there is an excellent effect of preventing the equipment from being stopped.

As described above, the paper sheet stacking height sensing apparatus of the present invention has been described with reference to the preferred embodiments and the accompanying drawings, which are not intended to limit the technical scope of the present invention, but are intended to help the understanding of the present invention.
