That is, the bolt 132 fixed to the upper plate 121 is raised by the rotation of the nut 133, thereby vertically moving the vertical movement bracket 120 upward and downward.

In this embodiment, the adjusting member 131 is composed of the bolt 132 and the nut 133, but the structure is not limited because it can be applied to various structures.

The lifting cylinder 140 is fixed to the bottom surface of the upper side plate 121 of the vertical movement bracket 120 and has a lifting rod 141 moving downward in the downward direction.

The pressing unit 150 is installed at the tip of the lifting rod 141 of the lifting cylinder 140 and descends with the lifting rod 141 driven by the lifting cylinder 140. When the lifting rod 141 descends, The rotation member 153, the rotation bar 160, and the elastic member 165 by pressing the paper sheet 1 with elasticity while rotating in a state of being in contact with the upper surface of the plate member 1, .

The fixing member 151 is fixed to the tip of the lifting rod 141 in the shape of a rectangular plate and has a rotation protrusion 152 protruding downward on the left side of the fixing member 151 (Figs. 6 and 7) Respectively.

The rotary member 153 is rotatably coupled to the rotation protrusion 152 on the lower side of the fixing member 151 and has a contact roller 157 which is in contact with the upper surface of the paper sheet 1 at one side.

In order to apply the above structure, the rotary member 153 is formed with a rotary coupling piece 154 which is coupled to the rotary protrusion 152 of the fixing member 151 through the rotary pin 155, 6 and 7), there is formed a roller engaging piece 156 to which a contact roller 157 that contacts the upper surface of the paper sheet 1 is engaged.

The elastic member 165 is brought into contact with the upper surface of the paper sheet 1 on which the contact roller 157 is stacked through the descent of the lifting rod 141. Thereafter, when the descending of the lifting rod 141 is continued, 153 are supported by the elastic member 165 so that the load applied from the lifting rod 141 is dispersed.

If the load applied from the lifting rod 141 is transmitted to the paper sheet material 1 through the contact roller 157 without the rotation of the rotary member 153 and the elastic member 165, Resulting in defective products.

The detection sensor 180 is fixed to the second slot 124a formed on the one side plate 124 of the vertical movement bracket 120 and is connected to the rotation bar 160 according to the rotation of the rotation member 153 of the pressing unit 150. [ When the rotation bar 160 is sensed, the driving of the lift in which the paper sheet material 1 is stacked is stopped, and when the rotation bar 160 is not detected, the upper side of the laminated paper sheet material 1 It is determined that the paper sheet 1 is exhausted and the upper end of the paper sheet material 1 stacked through the lift is moved to the initial position.

At this time, it is preferable that the detection sensor 180 is a proximity sensor, so that the detection according to the rotation of the rotation bar can be accurately performed, thereby assuring the promptness of the lift driving.

In this embodiment, since the rotation bar 160 can be detected through various sensors, the type of the sensor is not limited.

It is preferable that the horizontal moving plate 110 is provided with an alignment unit 170 for aligning the rear surfaces of the sheet materials 1 fed in a stacked state on the rear surface of the vertical piece 112.

The aligning unit 170 includes an aligning cylinder 171 having an aligning rod 172 disposed at the rear of the horizontal moving plate 110 as shown in Figs. 6 and 8 and having an ascending and descending position, And an alignment bar 173 formed as a vertical plate and supporting the rear surface of the laminated paper sheet 1.

At this time, it is preferable that the lower end of the alignment bar 173 in the longitudinal direction is further formed with a guide surface 173a which is bent obliquely in a direction opposite to the laminated paper sheet 1, Even if a part of the plate material 1 is in a disordered state, it is aligned by the guidance of the guide surface 173a in the ascending process.

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

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

At this time, the distance between the uppermost layer of the laminated paper sheet material 1 by moving the vertical movement bracket 120 in the vertical direction using the adjusting member 131 and the rotating member 153 descending by the lifting rod 141 is Setting.

That is, as shown in Fig. 10, the setting is such that the contact roller 157 of the rotating member 153 can apply pressure to the surface of the paper sheet 1.

The set value according to the above setting is input to a control device (not shown), and the control device receives and computes a set value and a signal transmitted from the detection sensor 180, thereby raising and lowering the stacked lift of the paper sheet 1 .

When the vertical movement of the vertical movement bracket 120 is completed, the horizontal movement plate 110 is moved in the left direction of the drawing of FIG. 10 while holding the handle 113 of the horizontal movement plate 110, Are stacked on the back side of the paper sheet material 1 so as to be supported in an aligned state.

At this time, since the aligning bar 173 is lowered by driving the aligning cylinder 171 as shown in FIG. 10, one side of the aligning bar 173 pushes the rear side of the laminated paper sheet 1.

Thereafter, the pressurizing unit 150 is lowered by the lifting cylinder 140.

The lowering of the pressurizing unit 150 is continued until the contact roller 157 reaches the position shown in Fig. 10 along the direction of the arrow of the contact roller 157 in the state where the contact roller 157 first contacts the upper surface of the laminated paper sheet 1 do.

At this time, the rotary member 153 rotates about the rotation protrusion 152 so that the contact roller 157 proceeds, and in this process, the contact roller 157 is rotated by the rotation of the rotary member 153, Thereby pressing the upper surface of the substrate 1.

At the same time, the elastic member 165 is contracted by the rotating member 153 rotating as shown in Fig. 10 to give elasticity to the rotating member 153 so that the lowering pressure of the lifting rod 141 is applied to the upper surface of the paper sheet 1 .

At this time, the rotary bar 160 is interlocked with the rotary member 153 and sensed by the sensing sensor 180 as shown in FIG.

In this case, the detection sensor 180 transmits the sensed signal to the control device, and the control device judges that the sheet material 1 can be drawn out one by one, so that the sheet material 1 stacked on the lift is not elevated Do not.

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

In this process, the rotation member 153 is gradually rotated by the repulsive force of the contracted elastic member 165 and the paper sheet 1 drawn out. At this moment, ≪ / RTI >

In this case, the control device recognizes this and drives the lift in the upward direction to position the uppermost layer of the laminated paper sheet 1 as shown in FIG.

At this time, the rotating member 153 again presses the upper surface of the paper sheet 1 as shown in FIG.

Since the above process is performed by the detection sensor 180 sensing the rotating bar 160, the paper sheet 1 stacked on the lift is repeatedly processed until it is exhausted.

The feeding belt variable device 200 is configured such that the first and second moving blocks 215 and 215 'are connected to the first and second vertical blocks 212 and 212' through the first and second feeding belts 219 and 219 ' The first main plate 211 and the second main plate 211 ", which are provided so as to be movable in a state of being accommodated in the first and second feeding belts 219, 219" And a pair of vertical plates 210 for shifting the position of the first and second feeding belts 219 and 219 'in accordance with the size and thickness of the paper sheet material 1 to convey the paper sheet material 1 in the Y- A feeding unit 220; An X-axis moving unit (not shown) which supports the pair of vertical plates 210 in an upright state and moves the first and second vertical blocks 212 and 212 'of the vertical plate 210 in both X and Y directions, 230 and the first and second movable blocks 215 and 215 'while being fixed to the main base 201.
