Description

  The present invention relates to a transport device that transports personnel from a starting point boarding / unloading unit to an ending point side boarding / unloading unit, such as an escalator or a moving sidewalk, by placing a person on the transport surface of a staff transport mechanism. Thus, the present invention relates to a transfer device that facilitates the user to get on and off between the start point or end point part of the floor surface and the start point side getting on / off part of the personnel transfer mechanism or the end point side getting on / off part.

In some conventional escalators, the moving speed of the steps is reduced at the getting-on / off part and at the intermediate part to make it easier for the user to get on and off, and to improve the transportation efficiency. In other words, a variable speed traction device is provided that extends in the horizontal direction and pulls each step while changing the moving speed over the lower floor side getting-on / off part and the required range of the front and rear parts of the lower floor side. The required range is a deceleration part where the base step and the overhanging step are gradually deepened and shrunk, and the moving speed is gradually reduced. The acceleration part where the moving speed gradually increases as the step is gradually separated and extended, and the base step and the overhanging step are extended apart from this acceleration part to the next deceleration part. It is configured as a high-speed portion that moves at high speed by being hooked and pulled by a step ahead in the traveling direction (see, for example, Patent Document 1).
JP 11-79640 A

  However, in the above-mentioned conventional escalator, the speed of the step is certainly reduced at the getting-on / off part and increased at the intermediate part, so that the user can easily get on and off, and the transportation efficiency may be improved. However, there is a variable speed traction device that extends in the horizontal direction and pulls each step while changing its moving speed over the lower floor side getting on and off part and the required part of the horizontal part before and after it. The speed reduction part and the acceleration part provided between them have a structure in which the base step and the overhanging step are deeply overlapped to expand and contract, and the structure is complicated as a whole. In addition, it is necessary to provide the variable speed traction device as described above. For these reasons, it has not been possible to modify the existing escalator using a constant escalator.

  Therefore, the present invention addresses such problems, and with a simple structure, the user's between the starting point or end point part of the floor surface and the starting point side getting on / off part or end point side getting on / off part of the personnel transport mechanism. It is an object of the present invention to provide a transfer device that can easily get on and off.

  In order to achieve the above-described object, the transport device according to the present invention is provided with a personnel transport mechanism that is formed in an endless belt shape and is driven to rotate between a start point portion and an end point portion that are separated by a predetermined distance on the floor surface. A transport device that transports personnel from a starting point boarding / unloading unit to an ending point boarding / unloading unit by placing a person on the transport surface, the starting point side boarding / stopping unit and the end point side boarding / unloading unit at both ends of the personnel transport mechanism, and the floor An installation space is provided between the start point portion and the end point portion of the surface, and the driving force is supplied from the personnel transport mechanism in these installation spaces to decelerate at a predetermined rate with respect to the transport speed of the personnel transport mechanism. A transfer traveling unit that is driven and travels in the horizontal direction is provided.

  With such a configuration, it is installed in the installation space provided between the starting point side getting on / off part and the end point side getting on / off part at the both ends of the person conveying mechanism and the starting point part and the end point part of the floor surface, respectively. By getting on and off via the transfer traveling unit that is decelerated at a predetermined rate with respect to the conveyance speed, for example, the speed difference when the user changes from the starting point part of the floor surface to the starting point side getting on and off part of the personnel conveying mechanism. Decrease. Similarly, the speed difference when the user moves from the end point getting on / off portion of the personnel transport mechanism to the end point portion of the floor surface is reduced.

As a result, it is possible to get on and off the moving sidewalk via the transfer running section, and the speed difference when changing is reduced.

  Furthermore, the driving force is supplied from the personnel transport mechanism to the transfer traveling unit by taking out the driving force from a rotating shaft of a sprocket that rotationally drives the personnel transport mechanism using a chain or a toothed belt. It is transmitted to the sprocket of the part. As a result, the driving force is taken out from the personnel transport mechanism, and the driving force is supplied to the transfer traveling unit.

  The transfer travel unit is driven to decelerate at a rate of approximately ½ of the transport speed of the personnel transport mechanism. Thereby, the speed difference at the time of boarding / exiting to a personnel conveyance mechanism via a transfer running part from a floor surface becomes about 1/2.

  According to the first aspect of the present invention, when the user gets on and off through the transfer traveling unit that is driven to decelerate at a predetermined rate with respect to the conveyance speed of the personnel conveyance mechanism, for example, the user starts from the start point of the floor to the personnel. The speed difference when changing to the starting point side boarding / alighting part of the transport mechanism can be reduced. Similarly, it is possible to reduce the speed difference when the user moves from the end point side getting on / off portion of the personnel transport mechanism to the end point portion of the floor surface. Therefore, it is possible to easily and safely get on and off between the start point or end point part of the floor surface and the start point side getting on / off part or the end point side getting on / off part of the personnel conveyance mechanism. In addition, since the transfer travel unit is only added to the personnel transport mechanism that is the main part of the transport apparatus, the structure is simplified as a whole. Furthermore, since the structure of the personnel transport mechanism need not be changed, it can be modified by using an escalator having a constant transport speed.

  Further, according to the invention according to claim 2, in the escalator, it is possible to get on and off via the transfer traveling unit that is driven to decelerate at a predetermined rate with respect to the transfer speed of the personnel transfer mechanism, and the speed difference when changing Can be reduced. Accordingly, it is possible to easily get on and off between the start point or end point part of the floor surface and the start point side getting on / off part or the end point side getting on / off part of the personnel conveyance mechanism.

  Further, according to the invention according to claim 3, on a moving sidewalk, it is possible to get on and off via the transfer traveling unit that is decelerated and driven at a predetermined rate with respect to the conveyance speed of the personnel conveyance mechanism, and the speed when changing The difference can be reduced. Accordingly, it is possible to easily get on and off between the start point or end point part of the floor surface and the start point side getting on / off part or the end point side getting on / off part of the personnel conveyance mechanism.

  Furthermore, according to the invention which concerns on Claim 4, a driving force can be taken out from the part which rotationally drives a personnel conveyance mechanism, and a driving force can be supplied to a transfer running part. Therefore, it is not necessary to provide a separate drive source for driving the transfer travel unit, and the structure is simplified.

  Moreover, according to the invention which concerns on Claim 5, the speed difference at the time of boarding / alighting to a personnel conveyance mechanism via a transfer running part from a floor surface can be made into about 1/2. Therefore, it is possible to easily and safely get on and off between the start point or end point part of the floor surface and the start point side getting on / off part or the end point side getting on / off part of the personnel transport mechanism.
