Hereinafter, an embodiment of the man conveyor and the gate device for the man conveyor will be described with reference to FIGS. 1 to 10. In each drawing (the same applies to FIGS. 11 and 12), the dimensional ratio of the drawings does not always match the actual dimensional ratio, and the dimensional ratios between the drawings do not necessarily match. do not have.

As shown in FIGS. 1 and 2, the man conveyor 1 according to the present embodiment sandwiches the structure 11 installed on the skeleton, the transport unit 12 for transporting a person, and the transport unit 12 in the first direction D1. It is provided with a pair of balustrade portions 13 (only one is shown in FIGS. 1 and 2) arranged in. Further, the man conveyor 1 includes a drive unit 14 for driving the transport unit 12 and the balustrade unit 13, and a control unit 15 for controlling the entire device.

In each figure, the first direction D1 is the first horizontal direction D1 which is a direction parallel to the horizontal direction, and the second direction D2 is a direction parallel to the horizontal direction and is the first horizontal direction D1. The second horizontal direction D2 is orthogonal to each other, and the third direction D3 is the vertical direction D3 orthogonal to the first horizontal direction D1 and the second horizontal direction D2.

The man conveyor 1 according to the present embodiment is an escalator having a stepped tread for transporting a person, but the structure is not limited to this. For example, the man conveyor 1 may be a moving walkway (moving walkway) having a flat tread for transporting a person.

For example, as in the present embodiment, the transport unit 12 is rotatable about an annular traveling unit 12a that rotates endlessly by being driven by the driving unit 14 and a first lateral direction D1 with respect to the traveling unit 12a. It may be provided with a plurality of steps 12b which are connected to and have a tread on which a person rides. Then, in step 12b, for example, in the region where the tread surface is exposed, the step 12b moves along the transport direction for transporting a person.

Further, for example, a pair of traveling portions 12a may be provided apart from each other in the first lateral direction D1, and the plurality of steps 12b may be arranged between the pair of traveling portions 12a and 12a. Then, the step 12b may be configured to be rotatably connected to each traveling portion 12a. Although not particularly limited, the traveling portion 12a may be, for example, a roller chain.

The balustrade portion 13 includes an annular handrail belt 13a that rotates endlessly when driven by the drive portion 14. The balustrade portion 13 may include, for example, a balustrade main body portion 13b that supports the handrail belt 13a and a guard portion 13c that is arranged at the lower portion, as in the present embodiment.

The drive unit 14 includes a drive source 14a for traveling the step 12b and rotating the handrail belt 13a. Then, for example, as in the present embodiment, the drive unit 14 has a pair of first drive rotation units 14b, 14b around which the traveling unit 12a is wound so that the step 12b is inverted, and a handrail belt 13a. The two drive rotation unit 14c may be provided with a drive transmission unit 14d that transmits the drive of the drive source 14a to the first and second drive rotation units 14b and 14c.

As a result, the drive source 14a for moving the step 12b and the drive source 14a for rotating the handrail belt 13a are the same. The first and second drive rotating portions 14b and 14c may be configured to rotate about the first lateral direction D1, for example. Further, although not particularly limited, the drive source 14a can be, for example, a motor, and the first and second drive rotation units 14b, 14c can be, for example, a sprocket.

Further, the man conveyor 1 is provided with a boarding port 1a on which a person rides on step 12b at the upstream end in the transport direction, that is, at the end of the second lateral direction D2. Although not particularly limited, for example, when the man conveyor 1 transports a person diagonally upward as in the present embodiment, the entrance 1a is arranged at the lower end portion of the man conveyor 1. For example, when the man conveyor 1 conveys a person diagonally downward, the entrance 1a is arranged at the upper end of the man conveyor 1.

As shown in FIGS. 3 and 4, the man conveyor 1 includes a gate device for the man conveyor 1 (hereinafter, also simply referred to as “gate device”) 2 arranged at the entrance 1a. In this embodiment, two gate devices 2 are provided. The gate device 2 may be detachably configured on the balustrade portion 13 as in the present embodiment, for example.

The gate device 2 includes a gate 3 that opens and closes a part of the entrance 1a. That is, the gate 3 is configured to move between the closed position where the entrance 1a is closed and the open position where the entrance 1a is opened. Further, the gate device 2 may include a housing 4 as in the present embodiment, for example. It is preferable that at least a part of the gate 3 is always arranged outside the housing 4 and exposed.

In the present embodiment, the gate 3 of one gate device 2 opens and closes about half of the area on one side of the first lateral direction D1, and the gate 3 of the other gate device 2 opens and closes the area of about half of the first lateral direction D1. It opens and closes about half the area on the other side of the. Then, for example, it is preferable that the gate 3 of one gate device 2 is located in the open position when the gate 3 of the other gate device 2 is located in the closed position. Thereby, for example, the position where the person rides on the step 12b can be divided into one side and the other side in the first lateral direction D1.

As shown in FIGS. 5 to 8, the gate device 2 transmits the rotational movement of the rotating body 5 to the gate 3 so that the rotating body 5 rotates by coming into contact with the handrail belt 13a and the gate 3 opens and closes. The transmission unit 6 is provided. The rotating body 5 and the transmission unit 6 may be arranged inside the housing 4, for example, as in the present embodiment.

The transmission unit 6 converts the unidirectional rotational motion of the rotating body 5 into a reciprocating motion and transmits it to the gate 3. For example, the transmission unit 6 has a first conversion unit 6a that converts a unidirectional rotary motion of the rotating body 5 into a linear reciprocating motion and a second conversion that converts the linear reciprocating motion into a rotary reciprocating motion as in the present embodiment. The configuration may be such that the portion 6b is provided.

For example, the first conversion unit 6a has a link unit 6d rotatably connected to the rotating body 5 by the first axis 6c, a slide unit 6f rotatably connected to the link unit 6d by the second axis 6e, and a slide. A guide portion 6g for guiding the portion 6f may be provided. With such a configuration, the rotating body 5 rotates in one direction with respect to the first lateral direction D1, and the slide portion 6f reciprocates linearly along the second lateral direction D2.

Further, for example, the second conversion unit 6b includes a rotation unit 6h that rotates and reciprocates around the vertical direction D3 by engaging with the slide unit 6f, and the gate 3 has a rotation unit 6h. It may be fixed to the rotating portion 6h so as to rotate as a unit. Although not particularly limited, the slide portion 6f and the rotation portion 6h may be configured to have teeth that mesh with each other, that is, the slide portion 6f is a rack and the rotation portion 6h is a pinion.

In this way, the rotating body 5 is driven by the handrail belt 13a, and the rotating body 5 rotates in one direction, so that the gate 3 is in the closed position (FIGS. 5 and 6) and the open position (FIGS. 7 and 8). ) And reciprocating rotation. Therefore, for example, the movable region of the gate 3 (the region through which the gate 3 passes) can be made smaller than that of the configuration in which the gate 3 rotates in one direction.

Further, in the present embodiment, since the gate device 2 is driven by the handrail belt 13a, the drive source 14a for opening and closing the gate 3 is the same as the drive source 14a for moving the step 12b. As a result, when step 12b is moving, the gate 3 continuously opens and closes.

Therefore, since the gate 3 continuously (without stopping) the opening / closing operation while the step 12b is moving, the opening / closing operation of the gate 3 can be easily predicted. As a result, for example, it is possible to prevent a person from colliding with the gate 3 when the person passes through the gate device 2 to get on the step 12b.

Further, since the drive source 14a for opening and closing the gate 3 is the same as the drive source 14a for moving the step 12b, the speed of the opening and closing operation of the gate 3 does not require any special control, and the speed of the opening / closing operation of the gate 3 does not require any special control. It changes in synchronization with the change in movement speed. Specifically, as the moving speed of step 12b becomes faster, the opening / closing operation of the gate 3 becomes faster, and as the moving speed of step 12b becomes slower, the opening / closing operation of the gate 3 becomes slower. ..

Therefore, the switching timing between the open position and the closed position of the gate 3 can be made constant (not only completely the same but also substantially the same) with respect to the moving distance in step 12b. That is, every time step 12b moves a certain distance, the opening and closing of the gate 3 is repeated. Thereby, for example, even if the speed of step 12b changes, the position where the person rides on step 12b can be similarly distributed to one side and the other side of the first lateral direction D1.

For example, as in the present embodiment, the direction in which the gate 3 moves from the closed position to the open position is the direction toward step 12b (in each figure, the direction opposite to the arrow direction of the second lateral direction D2). Is preferable. As a result, the direction in which the gate 3 moves from the closed position to the open position is the same as the direction in which the person goes on step 12b. Thus, for example, it is possible to facilitate a person to pass through the gate device 2 and get on step 12b.

By the way, even if the opening / closing operation of the gate 3 can be easily predicted, there is a risk that a person will collide with the gate 3. On the other hand, as shown in FIGS. 9 and 10, the gate 3 includes a deformable portion 3a that can be deformed with respect to an external force. Although not particularly limited, the deformed portion 3a may be configured to maintain the deformed state when an external force does not act again, for example, as in the present embodiment.

For example, the gate 3 has a base portion 3b fixed to the rotating portion 6h of the transmission portion 6, a movable portion 3c movable with respect to the base portion 3b, and a movable portion 3c having a vertical direction D3 with respect to the base portion 3b. It may be configured to include a torque hinge portion 3d that is rotatably connected to the shaft. That is, the movable portion 3c and the torque hinge portion 3d may form a deformable portion 3a.

As a result, for example, when a person hits the movable portion 3c and an external force acts on the movable portion 3c, the movable portion 3c rotates with respect to the base portion 3b. Therefore, as the person hits the gate 3, the deformed portion 3a of the gate 3 is deformed, so that the impact given to the person can be reduced. When no external force is applied to the movable portion 3c, the position of the movable portion 3c with respect to the base portion 3b is held by the torque hinge portion 3d.

Then, the housing 4 may be provided with the restoration portions 4a and 4b for restoring the deformation of the deformation portion 3a, for example, as in the present embodiment. For example, the restoration portions 4a and 4b may be configured to restore the deformation of the deformation portion 3a by hitting the gate 3 deformed by the deformation portion 3a. The restoration units 4a and 4b have a first restoration unit 4a that restores the deformation of the deformation unit 3a when the gate 3 is in the open position, and a deformation unit 3a when the gate 3 is in the closed position. It may be provided with a second restoration unit 4b to be restored.

From the above, as in the present embodiment, the man conveyor 1 includes a plurality of steps 12b that move in the transport direction, and a gate 3 that opens and closes at least a part of the entrance 1a. Is preferably configured such that the opening / closing operation is continuously performed while the step 12b is moving.

According to such a configuration, since the gate 3 opens and closes at least a part of the entrance 1a, it is possible to prevent a person from getting on the step 12b when the entrance 1a is closed by the gate 3. Then, since the gate 3 continuously performs the opening / closing operation while the step 12b is moving, the opening / closing operation of the gate 3 can be easily predicted.

Further, as in the present embodiment, the gate device 2 for the man conveyor 1 is a rotating body that rotates by being in contact with a gate 3 that opens and closes at least a part of the entrance 1a and a handrail belt 13a that rotates endlessly. It is preferable to include 5 and a transmission unit 6 for transmitting the rotational movement of the rotating body 5 to the gate 3 so that the gate 3 performs an opening / closing operation.

According to such a configuration, since the gate 3 opens and closes at least a part of the entrance 1a, it is possible to prevent a person from getting on the step 12b when the entrance 1a is closed by the gate 3. Then, when the handrail belt 13a is rotating endlessly, the gate 3 continuously opens and closes, so that the opening and closing operation of the gate 3 can be easily predicted.

Further, as in the present embodiment, in the man conveyor 1, it is preferable that the speed of the opening / closing operation of the gate 3 changes in synchronization with the change of the moving speed of the step 12b.

According to such a configuration, the speed of the opening / closing operation of the gate 3 changes in synchronization with the change of the moving speed of the step 12b, so that the timing of opening / closing the entrance 1a is changed according to the moving speed of the step 12b. be able to. Thereby, the switching timing of opening and closing of the gate 3 can be made constant with respect to the moving distance in step 12b.

Further, as in the present embodiment, in the man conveyor 1, it is preferable that the drive source 14a for opening and closing the gate 3 is the same as the drive source 14a for moving the step 12b.

According to such a configuration, since the drive source 14a for moving the step 12b also performs the opening / closing operation of the gate 3, the speed of the opening / closing operation of the gate 3 does not require any special control, and the moving speed of the gate 3b is not required. It changes in synchronization with the change of.

Further, as in the present embodiment, it is preferable that the man conveyor 1 includes a transmission unit 6 that converts a unidirectional rotational motion into a reciprocating motion and transmits the reciprocating motion to the gate 3.

According to such a configuration, the transmission unit 6 converts the rotational motion in one direction into a reciprocating motion and transmits the reciprocating motion to the gate 3, so that the gate 3 performs an opening / closing operation by performing the reciprocating motion. Thereby, for example, the movable area of the gate 3 can be reduced.

Further, as in the present embodiment, in the man conveyor 1, it is preferable that the gate 3 includes a deformable portion 3a that can be deformed by an external force.

According to such a configuration, since the deforming portion 3a is deformed by an external force, the deforming portion 3a can be deformed in the unlikely event that a person collides with the gate 3. This makes it possible to reduce the impact on humans.

The man conveyor 1 and the gate device 2 are not limited to the configuration of the above-described embodiment, and are not limited to the above-mentioned operation and effect. Of course, the man conveyor 1 and the gate device 2 can be modified in various ways without departing from the gist of the present invention. For example, it is of course possible to arbitrarily select one or a plurality of configurations and methods according to the following various modified examples and adopt them in the configurations and methods according to the above-described embodiment.

(1) In the man conveyor 1 according to the above embodiment, the gate device 2 is configured to be detachably attached to the balustrade portion 13. However, the man conveyor 1 is not limited to such a configuration. For example, as shown in FIGS. 11 and 12, the gate device 2 may be permanently installed in a detachable manner.

(2) Further, in the man conveyor 1 according to the above embodiment, the gate device 2 includes a rotating body 5 in contact with the handrail belt 13a, that is, is driven by the handrail belt 13a. However, the man conveyor 1 is not limited to such a configuration. For example, as shown in FIGS. 11 and 12, the gate device 2 may be connected to the first drive rotation unit 14b of the drive unit 14, that is, may be driven by the first drive rotation unit 14b. ..

For example, in the gate device 2 according to FIGS. 11 and 12, as in the above embodiment, the first conversion unit 6a that converts the unidirectional rotational movement of the first drive rotation unit 14b of the drive unit 14 into a linear reciprocating motion.

Then, as shown in FIG. 12, the second conversion unit 6b may include a plurality of rotation units 6h, 6i, 6j that rotate about the vertical direction D3.

For example, the first rotating portion (for example, a pinion) 6h rotates and reciprocates around the vertical direction D3 by engaging with the sliding portion (for example, a rack) 6f. The second rotating portion 6i is configured to rotate in conjunction with the first rotating portion 6h, and the third rotating portion 6j is configured to rotate in conjunction with the gate 3. The conversion unit 6b may be configured to include a transmission material (for example, a belt, a chain) 6k wound around the second rotation unit 6i and the third rotation unit 6j.

In the gate device 2 according to FIGS. 11 and 12, the gate 3 has a first closed position that closes one side of the first lateral direction D1 of the entrance 1a and the other of the first lateral direction D1 of the entrance 1a. It reciprocates and rotates between the second closed position that closes the side. As a result, the gate device 2 has a state in which one side of the first lateral direction D1 of the entrance 1a is closed, a state in which the entrance 1a is opened, and a state in which the other side of the first lateral direction D1 of the entrance 1a is closed. I'm repeating.

The speed of operation changes in synchronization with the change in the moving speed in step 12b. However, the man conveyor 1 and the gate device 2 are not limited to such a configuration.

For example, the drive source for opening and closing the gate 3 may be different from the drive source 14a for moving the step 12b. Specifically, the gate device 2 may be configured to include another drive source (for example, a motor) that opens and closes the gate 3. Then, for example, the speed of the opening / closing operation of the gate 3 may be constant regardless of the change in the moving speed of the step 12b.

(4) Further, in the man conveyor 1 and the gate device 2 according to the above embodiment, the transmission unit 6 is configured to convert the rotational motion in one direction into a reciprocating motion and transmit it to the gate 3.

For example, the transmission unit 6 may include a first conversion unit 6a that converts a one-way rotary motion into a curved reciprocating motion, and a second conversion unit 6b that converts the curved reciprocating motion into a rotary reciprocating motion. good. Although not particularly limited, the first conversion unit 6a may convert a unidirectional rotational motion into a curved (arc) reciprocating motion by, for example, a link mechanism. As described above, the configuration of the transmission unit 6 is not particularly limited, and for example, the transmission unit 6 may be configured by combining a link mechanism, a gear mechanism, and the like.

(6) Further, in the man conveyor 1 and the gate device 2 according to the above embodiment, the gate 3 includes a deformable portion 3a that can be deformed with respect to an external force, and the gate device 2 restores the deformation of the deformable portion 3a. The configuration is such that the restoration units 4a and 4b are provided. However, the man conveyor 1 and the gate device 2 are not limited to such a configuration.

(6-1) For example, the gate 3 may be configured not to be deformed by an external force. In such a configuration, for example, the gate device 2 may include a stopping means for stopping the opening / closing operation of the gate 3 when an external force acts on the gate 3. For example, the transmission unit 6 may be provided with a torque limiter as a stopping means.

(6-2) Further, for example, the gate 3 may be configured so that the deformation of the deformed portion 3a can be restored by eliminating the external force. Although not particularly limited, the deforming portion 3a may be configured to include, for example, an elastic material (for example, a spring) that elastically deforms when an external force acts on the gate 3.

Further, for example, the deforming portion 3a may be configured to be permanently deformed (for example, broken) by an external force acting on the gate 3. In such a configuration, for example, the gate 3 may be formed of styrofoam or the like, and the gate 3 may be replaced each time it is deformed (for example, broken).
