  In a conventional passenger conveyor device, a transport band formed by connecting a large number of treads in an endless manner is provided on the main frame, and a tread chain of the transport band is wound around a tread wheel chain. Then, the treadle chain drive is driven by the driving machine provided on the main frame via the winding transmission means, and the transport belt is configured to circulate through the main frame and transport passengers on the transport belt.

Is provided. (See Patent Document 1).

Japanese Examined Patent Publication No. 7-42070 (first to second pages, FIGS. 1 and 6)

  In the conventional passenger conveyor device, the driving rotary brake of the driving machine performs a braking operation when stopping the passenger conveyor, and the conveyance band brake performs a braking operation when an abnormality occurs in the winding transmission means. However, there are cases where both the drive rotation brake of the drive machine and the transport band brake perform a braking operation simultaneously due to the occurrence of an abnormality such as a power failure. And when both of the above brakes simultaneously during operation of the passenger conveyor, the transport zone suddenly stops and an excessive deceleration acts on passengers on the transport zone. For this reason, there has been a problem that passengers on the transport belt may lose balance due to excessive deceleration caused by the simultaneous braking operation of the both.

  In consideration of the simultaneous braking operation of both of the above, if each of the above is designed by setting the braking stop distance of the transport belt by the braking operation to be long, the braking stop distance at the time of each independent braking operation is Longer than the stopping distance during simultaneous braking. For this reason, when an abnormal situation requiring an emergency stop of the passenger conveyor occurs in a situation where the both do not perform a simultaneous braking operation, the braking stop distance of the transport belt exceeds the required braking stop distance.

  The present invention has been made to solve such a problem. For a transport zone that stops due to occurrence of an abnormality, it corresponds to the operation status at that time and corresponds to the operation status of the abnormality detector. The purpose of the present invention is to obtain a passenger conveyor device in which the abnormal stop deceleration of the belt is controlled to stop slowly.

  In the passenger conveyor device according to the present invention, the conveyor belt is endless and arranged in the main frame of the passenger conveyor and circulates, the conveyor belt provided on the main frame and wrapped around the conveyor belt, and the main frame A driving machine that is provided on the vehicle and drives the conveyor belt via the winding transmission means, a driving rotary brake that brakes the rotation of the driving machine, a conveyor belt brake that brakes the rotation of the conveyor belt, and a drive The slow stop flywheel pivotally attached to the rotary shaft of the machine, the electromagnetic clutch for intermittently operating the flywheel of the slow stop flywheel with respect to the rotary shaft of the drive machine, the drive rotary brake and the transport band brake are simultaneously An abnormal-time control device is provided that operates when operated and connects the flywheel action of the slow stop flywheel to the rotating shaft of the drive machine via the function of the electromagnetic clutch to slowly stop the transport belt.

  In the passenger conveyor device according to the present invention, when the passenger conveyor is in operation, a power failure occurs, the drive rotary brake brakes by an abnormality detector operation, etc., and at the same time, a power failure occurs, an abnormality detector operation of the winding transmission means Thus, when the transport band brake is braked, the abnormality control device is activated. Thus, the driving machine is de-energized, the driving rotary brake is braked, the transport band brake is braked, and the electromagnetic clutch is connected. Then, the slow stop flywheel is connected to the rotating shaft of the drive machine and rotates together by the function of the electromagnetic clutch.

  In this state, although the drive rotation brake and the transport band brake are simultaneously braked, the flywheel action of the slow stop flywheel acts on the drive system of the passenger conveyor formed by the drive or the like. For this reason, the conveyance belt gradually decelerates and stops at a preset stop distance. Therefore, even if both the drive rotation brake and the transport band brake are braked simultaneously due to the occurrence of an abnormality such as a power failure, the transport band will stop slowly, and excessive deceleration will not act on passengers on the transport band. . Accordingly, there is an effect of facilitating maintaining a stable posture of the passenger on the transport belt even when both of the above perform braking operation simultaneously.

FIG. 2 is a diagram conceptually showing a right side surface of a main frame in FIG. 3 is an enlarged view of a portion A in FIG. 2 and a main portion is shown in a longitudinal section, and FIG. 4 is a view showing a state in which the flywheel action in FIG. 3 is blocked. In the figure, a transport belt 4 formed in an endless shape is arranged on a main frame 1 of a passenger conveyor composed of escalators, in which a large number of footboards 2 are connected by a footboard chain 3.

  A transport belt 5 is provided on the main frame 1, and the transport belt 4 is wound around the transport belt 5 via the tread plate chain 3. In addition, a drive machine 6 is provided adjacent to the conveyor belt 5, and the drive machine 6 transmits the rotation of the motor 7, the speed reducer 8, and the shaft 9 of the motor 7 to the input shaft of the speed reducer 8. The flywheel 11 fixedly attached to the shaft 9 of the electric motor 7 and the drive rotation brake 12 provided on the input shaft of the speed reducer 8 are mainly configured.

  The drive rotary brake 12 is composed of an electromagnetic brake and is braked by a brake spring when the motor 7 is de-energized. When the motor 7 is energized, the electromagnetic mechanism is also energized and released against the pressing force of the brake spring. To do. And the winding transmission means 13 which transmits rotation of the output shaft of the reduction gear 8 to the conveyance belt 5 is provided, and the conveyance belt brake 14 which brakes the rotation of the conveyance belt 5 is provided on the main frame 1. The transport band brake 14 is normally held in a released state with the electromagnetic mechanism being energized, and the electromagnetic mechanism is de-energized due to the occurrence of an abnormality such as excessive elongation of the winding transmission means 13 and braking operation is performed via a spring force. Is configured to do.

  An electromagnetic clutch 15 is provided on the end surface of the electric motor 7. The electromagnetic clutch 15 is fixed to the shaft 9 of the electric motor 7 and has a mounting bracket 18 provided with a flange 16 at the end on the motor 7 side and a spline portion 17 provided on the opposite flange 16 side, and surrounds the outer periphery of the mounting bracket 18. The provided electromagnetic coil 19, the center of which is slidably fitted to the spline portion 17, and the side face of the electromagnetic coil 19 is arranged so as to face the electromagnetic coil 19. A compression coil spring 21 provided between 16 and the central portion of the disk 20 and a friction plate 22 mounted on the counter motor 7 side of the disk 20 are configured as main members.

  Then, a slow stop flywheel 23 is pivotally attached to the end of the shaft 9 of the electric motor 7, and the side surface thereof is arranged to face the friction plate 22 of the electromagnetic clutch 15. In the electromagnetic clutch 15, when the electromagnetic coil 19 is deenergized, the disk 20 is pressed against the slow stop flywheel 23 by the compression coil spring 21, and the electromagnetic clutch 15 is fixed between the fixed portion of the electromagnetic clutch 15 and the disk 20. A void B shown in FIG. 3 is formed.

  Further, in the electromagnetic clutch 15, when the electromagnetic coil 19 is energized, the disk 20 is attracted against the pressing force of the compression coil spring 21, and the slow stop flywheel 23 and the friction plate 22 are interposed between FIG. 4 and FIG. Is formed. An abnormality control device 24 is provided. Although not shown, the abnormality control device 24 is an abnormality detector for passenger conveyors such as an overspeed detector for the transport belt 4 and an abnormal elongation detector for the tread plate chain 3. In addition, it is connected to a break / excess elongation detector (not shown) of the winding transmission means 13, a drive rotation brake 12, a transport band brake 14, an electromagnetic clutch 15, and the like.

  The above-described abnormality detector corresponding to the cause of the abnormality is activated by the occurrence of an abnormality in the passenger conveyor, and the drive rotary brake 12 is braked through this operation. Further, the conveyance band brake 14 performs a braking operation through the operation of the breakage / excess elongation detector of the winding transmission means 13. Furthermore, if a power failure occurs during the operation of the passenger conveyor, both the drive rotary brake 12 and the transport band brake 14 are simultaneously braked. Then, by the simultaneous braking operation of both the above, the control device 24 at the time of abnormality is operated, and the slow stop flywheel 23 is connected to the shaft 9 of the electric motor 7, that is, the rotating shaft of the driving device 6 through the function of the electromagnetic clutch 15. The

  In the passenger conveyor device configured as described above, each of the drive unit 6, the drive rotary brake 12, the transport band brake 14 and the electromagnetic clutch 15 corresponds to the state of the passenger conveyor as shown in Table 1 below. To be controlled.

すなわち、乗客コンベヤーの第一状況として乗客コンベヤーが停止中であるときは、駆動機６は消勢、駆動回転制動機１２は制動、搬送帯制動機１４は制動の態様となり、電磁クラッチ１５は図３に示す接続状態、すなわち緩停止用フライホイール２３における慣性量すなわち、はずみ車作用がフライホイール１１のはずみ車作用と共に駆動機６等の乗客コンベヤーの駆動系に作用した態様となる。

That is, when the passenger conveyor is stopped as the first situation of the passenger conveyor, the drive unit 6 is de-energized, the drive rotary brake 12 is braked, the transport band brake 14 is braked, and the electromagnetic clutch 15 is 3, that is, the inertia amount in the slow stop flywheel 23, that is, the flywheel action acts on the drive system of the passenger conveyor such as the drive machine 6 together with the flywheel action of the flywheel 11.

When the passenger conveyor is in operation as the second situation of the passenger conveyor, the driving machine 6 is energized, the driving rotary brake 12 is released, the transport band brake 14 is released, and the electromagnetic clutch 15 is connected as described above. It becomes an aspect.
As a third situation of the passenger conveyor, the passenger conveyor is in operation, and the driver 6 is de-energized by human operation, or the driver 6 is operated by the operation of an abnormality detector such as an overspeed detector in the transport zone 4. When is stopped after being deenergized, the mode is as described below.

  That is, the drive machine 6 is de-energized, the drive rotary brake 12 is braked, the transport band brake 14 is released, the electromagnetic clutch 15 is shut off as shown in FIG. 4, that is, the flywheel action of the slow stop flywheel 23 is the drive machine 6 etc. It becomes the aspect which does not act on the drive system of a passenger conveyor. As a result, the drive unit 6 is braked by the braking function of the drive rotation brake 12, the transport band 4 is gradually decelerated by the flywheel action of the flywheel 11, and stops at a predetermined stop distance set in advance.

  At this time, since the electromagnetic clutch 15 is in the disconnected state, the slow-stop flywheel 23 is idled, and the flywheel action thereof does not act on the drive system of the passenger conveyor such as the drive machine 6. Further, after the passenger conveyor is stopped, the electromagnetic coil 19 of the electromagnetic clutch 15 is de-energized, and the idling continuation operation of the slow stop flywheel 23 is braked.

  Then, as a fourth situation of the passenger conveyor, when the passenger conveyor is in operation and the operation of the break detector of the winding transmission means 13 occurs, the following mode is set. That is, the driving machine 6 is energized, the driving rotary brake 12 is released, the transport band brake 14 is braked, and the electromagnetic clutch 15 is in the disconnected state shown in FIG. However, this does not act on the drive system of the passenger conveyor such as the drive machine 6. As a result, the rotation of the transport band vehicle 5 is braked by the braking function of the transport band brake 14, and the transport band 4 is decelerated to stop at a predetermined stop distance set in advance.

  Further, as a fifth situation of the passenger conveyor, when the passenger conveyor is in operation, a power failure occurs and the drive unit 6 is de-energized, and the conveyance band brake 14 is braked or the conveyance band 4 is overspeeded. When the operation of an abnormality detector such as a detector and the operation of the excessive elongation detector of the winding transmission means 13 occur and the drive rotation brake 12 and the transport band brake 14 are simultaneously braked, the following mode is adopted. . That is, at this time, the abnormality control device 24 is activated, the drive unit 6 is de-energized, the drive rotation brake 12 is braked, the transport band brake 14 is braked, and the electromagnetic clutch 15 is connected.

  As a result, the slow stop flywheel 23 is connected by the function of the electromagnetic clutch 15 to the state shown in FIG. 3 and rotates together with the shaft 9 of the electric motor 7. In this state, although the drive rotation brake 12 and the transport band brake 14 are simultaneously braked, the flywheel action of the slow stop flywheel 23 and the flywheel 11 is affected by the shaft 9 of the motor 7, that is, the passenger conveyor such as the drive 6. Acts on the drive train. For this reason, the conveyance belt | band | zone 4 decelerates gradually and stops by the predetermined stop distance set beforehand.

  Accordingly, even when both the drive rotation brake 12 and the transport band brake 14 are simultaneously braked due to an abnormality such as a power failure, the transport band 4 does not stop suddenly and is excessively reduced for passengers on the transport band 4. Speed does not work. For this reason, the passenger on the transport belt 4 can maintain a stable posture even when the both perform braking operation simultaneously.

  In addition, if the relationship between the brake torque, the inertia amount, and the stop distance in the passenger conveyor is arranged, the stop distance of the transport belt 4 is inversely proportional to the brake torque and proportional to the square of the inertia amount. When the brake torque is T, the inertial amount of the flywheel is I, and the stop distance is S, the following equation 1 is obtained.

ここで、ａ及びｂは乗客コンベヤーの運転条件やシステム性能により決まる定数である。厳密には慣性量として踏板２など駆動系全体の慣性量及びブレーキトルクとして踏板２などの走行ロスが影響するがここでは単純化のため省略する。
また、駆動回転制動機１２のブレーキトルクをＴ_Ｂ、搬送帯制動機１４のブレーキトルクをＴ_Ｍ、フライホイール１１の慣性量をＩ_１、緩停止用フライホイール２３の慣性量をＩ_２とする。

Here, a and b are constants determined by the operating conditions and system performance of the passenger conveyor. Strictly speaking, the inertia amount of the entire driving system such as the tread plate 2 as an inertia amount and the travel loss of the tread plate 2 as a brake torque are affected, but they are omitted here for simplification.
Further, the brake torque of the drive rotary brake 12 is T _B , the brake torque of the transport band brake 14 is T _M , the inertia amount of the flywheel 11 is I ₁ , and the inertia amount of the slow stop flywheel 23 is I ₂ . .

When the above-described passenger conveyor is stopped as a third situation, because the acting is the inertia amount I ₁ of the brake torque T _B and the flywheel 11 rotated brakes 12, the stopping distance S ₁ of the following Equation 2 is obtained.

また、前述の乗客コンベヤーが第五状況として停止する場合に、作用するのは駆動回転制動機１２のブレーキトルクＴ_Ｂ、搬送帯制動機１４のブレーキトルクをＴ_Ｍ、フライホイール１１の慣性量Ｉ_１及び緩停止用フライホイール２３の慣性量Ｉ_２であるので、停止距離Ｓ_２は次の式３のようになる。

In addition, when the above-described passenger conveyor stops as the fifth situation, the brake torque T _B of the drive rotary brake 12, the brake torque of the transport band brake 14 T _M , and the inertial amount I of the flywheel 11 act. since ₁ and the inertia amount I ₂ of slow stop the flywheel 23, the stopping distance S ₂ is as following equation 3.

なお、従来の乗客コンベヤー装置においては、式３における慣性量Ｉ_２を見込むことができず、停止距離は慣性量Ｉ_２分減少して急停止となる。これに対して、緩停止用フライホイール２３を設けてブレーキ力に合わせて慣性量を調整することによって、前述の乗客コンベヤーの第五状況に係わらず予め設定された適切な停止距離によって搬送帯を緩停止させることができる。

Note that in the conventional passenger conveyor apparatus can not be expected inertial quantity I ₂ in Formula 3, the stopping distance becomes abruptly stopped to decrease the inertia weight I ₂ minutes. On the other hand, by providing the slow stop flywheel 23 and adjusting the amount of inertia in accordance with the braking force, the transport band is set at an appropriate stop distance set in advance regardless of the fifth situation of the passenger conveyor. It can be stopped slowly.

  Further, by providing the slow stop flywheel 23 and the electromagnetic clutch 15 on the shaft 9 of the electric motor 7 that rotates at a high speed, a large inertia amount can be obtained with a small size. However, even in a configuration in which the slow stop flywheel 23 and the electromagnetic clutch 15 are provided on the input shaft, the output shaft, and the like of the speed reducer 8, the operation according to the embodiment of FIGS. 1 to 4 can be obtained. .

  Moreover, even if it is the structure which added the flywheel for slow stop and electromagnetic clutch different from the flywheel for slow stop 23 and the electromagnetic clutch 15 to the input shaft etc. of the reduction gear 8, Embodiment of FIG. The same effect can be obtained. Furthermore, the same operation as that of the embodiment of FIGS. 1 to 4 can be obtained for a passenger conveyor including a moving sidewalk in which the transport belt 4 is configured by a wide belt.

Embodiment 2. FIG.
FIG. 5 is a flowchart showing another embodiment of the present invention and explaining the operation of each device of the passenger conveyor. In addition, the passenger conveyor apparatus is comprised similarly to the above-mentioned FIGS. The passenger conveyor is equipped with various abnormality detectors (not shown) such as an overspeed detector for the transport belt 4 and is connected to an abnormality control device (not shown) to generate abnormalities for passengers and passenger conveyor equipment. When the abnormality is detected, the abnormality control device is operated to perform the abnormality control to stop the passenger conveyor.

  In addition, for example, when an abnormality detector that operates when a passenger puts shoes or the like in the gap between the treads 2 operates, it is necessary to immediately stop the passenger conveyor. However, if the passenger conveyor is immediately stopped in response to the operation of the abnormality detector having a relatively low degree of urgency, an excessive deceleration may act on the passenger on the transport belt 4 and the passenger may lose balance. In order to prevent the occurrence of such a situation, various abnormality detectors of the passenger conveyor are classified in advance into those that require an emergency stop and those that do not require an emergency stop.

  Hereinafter, the abnormality control by the operation of the abnormality control device for the operation of the abnormality detector will be described with reference to FIG. That is, when the passenger conveyor of step 101 is stopped and in a standby state, the drive unit 6 is de-energized, the drive rotary brake 12 is braked, and the electromagnetic clutch 15 is connected. Then, when the passenger conveyor is operated by proceeding to step 102, the process proceeds to step 103, where the drive rotary brake 12 is released and the drive unit 6 is energized to operate the passenger conveyor. If no driving operation is performed in step 102, the process returns to step 101.

  Next, the routine proceeds to step 104, and if the abnormality detector operates during operation of the passenger conveyor, the routine proceeds to step 105. If the abnormality detector does not operate in step 104, the process proceeds to step 106. If the passenger conveyor is not stopped, the process returns to step 103. If the passenger conveyor is stopped, the process proceeds to step 107. In step 105, if the operated abnormality detector does not require an emergency stop of the passenger conveyor, the process proceeds to step 107.

  In step 105, if the operated abnormality detector is an abnormality detector or the like that operates when a passenger puts shoes or the like in the gap between the treads 2, and if an emergency stop is required, the process proceeds to step 108. The driving machine 6 is de-energized, the driving rotary brake 12 is braked, and the electromagnetic clutch 15 is disconnected. In this situation, the inertia amount of the drive system of the passenger conveyor is small and the routine proceeds to step 109, where the passenger conveyor, that is, the transport belt 4 is quickly stopped. Next, the routine proceeds to step 110.

  Then, in step 110, the electromagnetic clutch 15 enters the connection mode, and the process returns to step 101. In step 107, the driving machine 6 is de-energized, the driving rotary brake 12 is in a braking mode, and the electromagnetic clutch 15 is in a connecting mode. In this situation, the inertia amount of the drive system of the passenger conveyor is large, and the process proceeds to step 111, where the passenger conveyor, that is, the transport belt 4 is stopped gently and the stop distance becomes relatively long. For this reason, the passenger | crew on the conveyance belt 4 can maintain the stable attitude | position at the time of operation | movement of the abnormality detector which does not require an emergency stop. Then, the process returns from step 111 to step 101.

Embodiment 3 FIG.
FIG. 6 also shows another embodiment of the present invention, and is a flowchart for explaining the operation of each device of the passenger conveyor. In addition, the passenger conveyor apparatus is comprised similarly to the above-mentioned FIGS. The passenger conveyor is equipped with various abnormality detectors (not shown) such as an overspeed detector for the transport belt 4 and is connected to an abnormality control device (not shown) to generate abnormalities for passengers and passenger conveyor equipment. When the abnormality is detected, the abnormality control device is operated to perform the abnormality control to stop the passenger conveyor.

  In the passenger conveyor such as an escalator in which the main frame 1 is inclined, the abnormality detector operates in a state where the passenger is on the transport belt 4 and the abnormality control is performed by the abnormality control device. When the passenger conveyor stops, the stopping distance becomes longer when the passenger conveyor is in the descending operation. Further, when the passenger conveyor is in the ascending operation, the stopping distance is shortened, and an excessive deceleration acts on the passengers on the transport belt 4 and the passengers may lose balance.

  With respect to such a situation, the abnormal control related to the driving direction by the operation of the abnormal control device when the abnormality detector operates in the passenger conveyor installed at an inclination will be described with reference to FIG. That is, when the passenger conveyor in step 201 is in a standby state, the drive unit 6 is de-energized, the drive rotary brake 12 is braked, and the electromagnetic clutch 15 is connected. Then, the process proceeds to step 202, and when the passenger conveyor is operated, the process proceeds to step 203 where the drive rotary brake 12 is released and the drive unit 6 is energized to operate the passenger conveyor.

  If no driving operation is performed in step 202, the process returns to step 201. Next, the routine proceeds to step 204, and if the abnormality detector operates during operation of the passenger conveyor, the routine proceeds to step 205. If the abnormality detector does not operate in step 204, the process proceeds to step 206. If the passenger conveyor is not stopped, the process returns to step 203. If the passenger conveyor is stopped, the process proceeds to step 207. In step 205, if the passenger conveyor is in the ascending operation, the process proceeds to step 207.

  In step 205, if the passenger conveyor is not in the ascending operation, the routine proceeds to step 208, where the driving machine 6 is de-energized, the driving rotary brake 12 is braked, and the electromagnetic clutch 15 is disconnected. In this situation, the inertia amount of the drive system of the passenger conveyor is small, and the process proceeds to step 209, where the passenger conveyor, that is, the transport belt 4 is stopped quickly, and the stop distance of the transport belt 4 becomes long when the ascending operation is not performed. To prevent that. Next, the routine proceeds to step 210, where the electromagnetic clutch 15 enters the connection mode and returns to step 201.

  In step 207, the driving machine 6 is de-energized, the driving rotary brake 12 is in a braking mode, and the electromagnetic clutch 15 is in a connecting mode. In this situation, the inertial amount of the driving system of the passenger conveyor is large, and the process proceeds to step 211, where the passenger conveyor, that is, the transport belt 4 is gently stopped and the stopping distance becomes relatively long. For this reason, the passenger | crew on the conveyance belt | band | zone 4 can maintain the stable attitude | position at the time of operation | movement of the abnormality detector in the passenger conveyor in climbing operation. Then, the process returns from step 211 to step 201.
