Abstract

This invention provides a man conveyor controller and a man conveyor, to reduce the switching shock and noise while not using the synchronous inspection device, to obtain a low-cost and highly reliable device. In switching from low to high speed operation, a driving electric motor (2) connected to a converter (1) connected to a commercial power supply (R, S, T) is disconnected from the converter (1) and then, with the residual voltage of the electric motor (2) dropped, the electric motor (2) is connected directly to the commercial power supply (R, S, T). Further, in switching from high to low speed operation, the driving electric motor (2) connected directly to the commercial power supply (R, S, T) is disconnected from the commercial power supply (R, S, T) and then, with the residual voltage of the electric motor (2) dropped, the electric motor (2) is connected to the converter (1). This makes it possible to achieve switching between low and high speed operations with an inexpensive arrangement and without a switching shock or noise.

Description of the invention (ui first, when the start switch 5 is switched to the rising side, in the +-3-4-5-7e-6--circuit, the rising contactor 6 is pushed, and the contact h will be Closed and contact 6e is opened. With contact 6d closed, the operating relay M is pushed, and contacts 8a and 8b are closed. At this time, when the speed switch 9 is switched to the low speed side, it is at + -8a —9—ι〇— _ In the circuit, the low-speed relay 1 〇 is pushed 'to form a self-protection circuit by closing the contact i 〇a. In addition, the contact 10 is also closed, and the contacts 10 d to 1 〇 f is open, and the time limit contact 10c is closed after a certain time limit.

Therefore, in the + 15b- > > 14--circuit, the vVVF device operation relay 14 is pushed, the contact 14a is closed, and the contact 14b is opened. By closing the contact 14a, in the + 8b ~ 14a-13c_nd-16 --- circuit, the contactor 16 for the VVVF device is pushed, the contacts 16a to 16d are closed, and the contact 16e is opened. At this time, the contact ioc is closed, and since the contact 16d is in a closed state, a low-speed start command is output, the VVVF device 1 is started, and its output frequency is increased to be printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Commercial Power and Economy.

Therefore, the electromagnetic brake (not shown) is released, and the motor 2 starts to perform low-speed rising operation. At this time, when the speed switch 9 is switched to the high-speed side, in the + -8a-9-9-11- circuit, the high-speed relay u is pushed, the contacts ua to 11d are closed, and the contact 11e is opened. . The low-speed relay 10 is released by the opening of the contact 1❺, the contacts 1 "to 10c are opened, and the contacts 10d to 1 Of are closed.

On the other hand, because the time limit contact 10c is open, and the time limit contact ⑴ = High: output of operation command, VVVF device 1 ^

" The source R, S, T increase with the same frequency, the motor 2 can accelerate the stomach V V VF device! When the output frequency is equal to the frequency of the commercial power supply R, s, and T, the contact 12 is closed, the power frequency detection relay is closed by the pressing contact Ua, and the contact 13b and the time limit contact 13c are open. The contact 10b is already open. Therefore, when the contact is open, the VVVF device operation relay 14 is released from pressing, and the contact is open! The contact 14b is closed. Since the contact Ua is open ', the contactor 16 for the VVVF device connection is released and the contacts 16a to 16d are opened, and the contact 16e is closed. In addition, because the contact 14 is closed, the switching time setting relay 15 is pushed in the 8 "⑶ 一 ι__ _ order circuit, and after a certain time, the time limit contact 15a is closed, and at +- ―In the circuit of 16 and 17 ', the power supply contactor 17 is pushed, and contacts 17a to nc are closed, and contact 17d is open.

Invention Description (13 of The phase difference of the shape is the maximum. As shown in Figure 4, when the operation time of the inverter 1C is reversed with the time ^ ^ ^, the motor 2 will be separated from the VVVF device yvvr device χ and added directly to the air. The voltage V2 will decrease according to the switching time D2. 切换 When switching is set by the relay "5", and-once the switching time T2 is over, the motor 2 is connected to the commercial power supply R, S, T 'and transferred to normal Running time D. In this way, when the switching time T2 is ensured, even if the output of the vvvf device r is not synchronized with the commercial power supply RST, as shown in Part A, a switching operation to reduce switching vibration can be achieved. This is achieved by making the motor 2 The idling reduces the residual voltage V3, so the switching vibration can be reduced. And it is better to set this switching time T2 at about 0.7 seconds to reduce the speed reduction of the human conveyor. For this, if As shown in FIG. 5, when the switching time of the motor 2 is D4, that is, when the idling time is short, the residual voltage V4 does not decrease, so as shown in part β, the “switching vibration also increases.” Turn to low-speed ascent operation as follows Now, the power contactor 7 is pushed, and the motor 2 is connected to the commercial power sources R, S, and T for high-speed rising operation. At this time, when the speed switch 9 is switched to the low-speed side, the low-speed Relay 丨 〇 is pushed 'and the high-speed relay 11 is released by the opening of the contact 10d. In addition,' the contact 10e is opened, so the switching time setting relay 15 is released and the time limit contact 15a is opened . Therefore, the contactor 17 for power supply is released, and the motor 2 is separated from the commercial power supply r, s, and t.

Description of the invention (l4) In addition, due to the switch-off time setting of the relay 15 to release the pressure, the contacts 15b will be closed. At this time, since the contact 10b is in a closed state, the VVVF device operation relay 14 is pushed and the contact 14a is closed. On the other hand, the contact 10f is opened due to the pressing of the low-speed relay 10, and after a certain period of time, the contact 13C is closed due to the time limit, so it is between + —8b — i4a — i3c — 17d — 16 — — In the circuit, the contactor 16 for the VVVF device is pushed, and the motor 2 is connected to the VVVF device}. That is, the motor 2 is temporarily separated from the commercial power sources R, S, T and idling, and then connected to the v v VF device i. At this time, as in the above-mentioned switching from low speed to high speed, since the residual voltage from the motor 2 is lowered before connection, the switching vibration can be reduced. After that, once the time limit contact 11 d is opened after a certain period of time has elapsed since the high-speed relay 11 was released, and the time limit contact 1 oc is closed after a short period of time since the low-speed relay 10 is pushed, the Vv device The output frequency of i will shift from the frequency of the commercial power sources r, S, and T to a low set frequency, and the motor 2 will decelerate. With the above structure, the residual voltage V3 of the motor 2 is lower than when starting to separate from the VV VF device or the commercial power supply R, S, T ', that is, after a certain period of time since the start of separation, such as connection Since it is connected to commercial power sources R, S, and T, or is connected to, for example, the vVVF device 1, it is possible to achieve a switching operation without switching vibration or noise with a low-cost configuration.
