CONSTITUTION:A slider 13 provided on a table 3 is engaged liftably with a guide rail 12 provided on the housing 11. Then one end of a chain 15 having the other end sucured to the slider 13 is geared through a sproket 16 with the sprocket 17a of an induction motor 17 and a ballance weight 20 is suspended from the leading edge. While a sensor 21 is provided at the position suitable for folding the continuous paper 2 in the housing 11 and connected through a control circuit 10D to the exciting coil 9e for relay 9D.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a method of controlling a power stacker device for folding perforated continuous paper.

(2) Background of the technology Normally, in this type of device, the top surface of the folded paper is placed at a predetermined height in the stacker device so that the paper is continuously stacked in good condition. Must be held in position.

(3) Prior art and problems Figure 3 is a sectional view showing a conventional power stacker device, Figure 4
The figure is a control block diagram of a conventional power stacker device.

The conventional power stacker device 1, as shown in FIG.
As the motor for driving the table 3 on which the continuous paper 2 is folded, a reversible motor 5 capable of one rotation in forward and reverse directions (6) is used. ') r, the goople 3 fixed on the belt 6 was moved vertically along the guide rail 7. However, in this method, for controlling the motor 5, relays 9A and 9B and a control circuit 10 for stopping and reversing the motor 5 are used, as shown in FIG.
A and 10B are required, which has the disadvantage that the circuit for controlling the motor becomes complicated and large.

(4) Object of the Invention In order to eliminate the above-mentioned drawbacks, it is an object of the present invention to provide a control method for a bower stacker device that can simplify and downsize a circuit for controlling a motor.

(5) Structure of the Invention In other words, the present invention is configured such that the table is raised using a motor and lowered by the table's own weight.

(6) Examples of the invention Hereinafter, the present invention will be described in detail based on the drawings.

FIG. 1 is a diagram showing an example of a power stacker device to which the present invention is applied, and FIG. 2 is a control block diagram of the power stacker device of FIG. 1.

As shown in FIG. 1, the power stacker device 1 includes a housing 1.
1, and a guide rail 12 is provided on the housing 11. A slider 13 having a table 3 on the top thereof is engaged with the guide rail 12 so as to be movable in the vertical direction in the figure, that is, in the directions of arrows A and B.
One end of a chain 15 is fixed to the slider 13. The chain 15 meshes with a sprocket 17a fitted to the output shaft of the induction motor 1T via a sprocket 16 rotatably supported by the housing 11.
Furthermore, the chain 15 connects the chain 15 to the sprocket 16.
Kite ball 19 provided to ensure reliable engagement with the
? The balance weight 20 is suspended from the tip thereof. A sensor 21 consisting of a light emitting element 21a and a light receiving element 21b is provided at a position of the housing 11 suitable for folding the continuous paper 2, and the sensor 21 is connected to a control circuit 101 as shown in FIG. )′
It is connected to the excitation coil 9e of the relay 9D via Jk. A power source 23 and an induction motor 17 are connected to a contact point 9f which is driven to open and close by a coil 9e of L/-9D.

Since the power stacker device 1 has the above configuration, when the device 1 is not in use, as shown in FIG. , the sensor 21 is driven and the light 21c is sent from the light-emitting cable 21a to the light-receiving element 211 when the folding is fully started.
), and as shown in FIG. 2, the output signal S1 of the sensor 21 becomes Ill, I. Then, the Mf control circuit 10
D is relay 9 after a certain period of time when signal S1 becomes 11L1.
1) The excitation coil 9ei is excited and the contact 9f is closed. Then, the motor 17 is driven together with the sprocket 17a, and the slider 13 and therefore the table 3 are moved along the guide rail 12 through the chain 15 in the direction of the arrow in FIG. The surface 3a faces the sensor 21, and light 21t;t: from the light emitting element 21a;
Pull it up with a cutting sword. When the light 21C is cut off, the output signal S1 becomes Hn, i1j! I side j circuit 10D←
- Stops the excitation of the coil 9e, opens the contact 9f, and stops driving the motor 17.

Surtur and Goople 3's ascent in the incoming direction is interrupted, and now they begin to gradually descend in the B direction due to their own weight. Furthermore, since a balance weight 20 is provided at the other end of the chain 15, the goople 3 is gently lowered. The table 3 is lowered after a certain period of time after the light 21C from the light-emitting cable 21a enters the light-receiving cable 211) again and the utility signal S1 becomes 11L'.
3a continues at a position lower than the sensor 21 by a certain distance, and then the motor 17 is driven again by the control circuit 10I) and the table 3 is raised.

On the other hand, a continuous sheet of paper 2 printed with a line printer or the like is sent from the printer in Figure 1 and is sequentially folded onto the folding surface 3a. 3, the folded paper 2 blocks the light 21ck from the sensor 21, so Google 3
The uppermost surface 2a of the folded paper 2 is positioned to face the sensor 21, that is, a position suitable for continuous folding of the paper 2. Therefore, paper 2 on table 3
The top surface 2a of the paper 2 is always held in the vicinity of the sensor 21 over a certain range in the directions of arrows A and B, and is raised by the motor 17 and lowered by the weight of the table 30.
The folding process is done in perfect condition. Incidentally, even if the paper 2 is tangled to some extent on the goople 3, the torque required by the motor 17 to pull up the goople 3 can be reduced due to the action of the balance weight 20.

(7) As described in detail, in the present invention, the raising of the table 3 is carried out using the motor of the induction motor 17#, and the lowering is carried out by the weight of the table 3. The control circuit 10 is used only when the table 3 is raised, and therefore it is sufficient to control the rotation of the motor in only one direction.
The number of A, IOB, and relays 9A and 9B can be halved, contributing to the simplicity and miniaturization of the circuit for controlling the motor. Since the motor is driven only when the table 30 is raised, the energization time is about half that of the conventional device, and it is possible to reduce power consumption and power consumption of the device 1.
