Description

  The present invention relates to a seismic isolation mechanism in a conveyor system of a belt conveyor type (hereinafter also referred to as a conveyor type or a conveyor type) installed in a building or between buildings.

  Conventionally, in offices, hospitals, libraries, etc., various other offices also run on conveyors laid in buildings or across buildings, buckets supported by rails and containers, etc. In addition, a transport facility is provided for unattended transport of documents and other articles to an arbitrary destination point.

  When an earthquake occurs in such a transport facility as described above, there is a risk that the conveyors and rails installed between the buildings may be displaced or broken due to the shaking of the buildings due to the earthquake. Such fears are particularly noticeable when the building's mode of vibration (vibration) is different, such as when one building has a seismic isolation structure and the other building has a seismic structure. Appear.

  The applicant of the present invention has previously proposed a seismic isolation mechanism useful as a rail-type transfer facility installed between buildings as Patent No. 3436896. Since it is a structure that uses the shearing of bolts to perform seismic isolation, there is a problem that it is indispensable to restore facilities such as bolts that have been broken after the earthquake has subsided.

On the other hand, in the so-called ferry system that does not continue the conveyance path between buildings disclosed in Patent Document 1 as the prior art, extra time is required for transfer in the part of the ferry system in normal conveyance, There is a problem that the conveyance efficiency is lowered.
Japanese Patent Laid-Open No. 2002-19604

  In view of the problems of the prior art as described above, the present invention provides a rational seismic isolation mechanism in a conveyor system of a belt conveyor type installed between a base isolation building and a non-base isolation building. Let it be an issue.

The structure of the seismic isolation mechanism of the present invention made for the purpose of solving the above problems is to separate the middle of a conveyor for transportation built in or between buildings with a space of an appropriate length, An intermediate conveyor having a length that is substantially the same as or partially overlapping between the opposite ends of the separated conveyor is suspended by a hanging stay above the separated conveyors. A baggage that is arranged so as to be able to swing back and forth with respect to the separated conveyor and is carried on the upper surface of the separated conveyor is hooked or suspended on an intermediate conveyor arranged between the separated conveyors. was supported become so as to convey, interrupted the separate conveyor conveying line thus luggage being displaced back and forth also the intermediate conveyor direction be displaced in its longitudinal direction by the vibration of an earthquake It is characterized in that it has a strange.

In addition, another configuration of the seismic isolation mechanism of the present invention is such that the middle of a conveyor for transportation built in or between buildings is separated with a space of an appropriate length, and the lower part between the separated conveyors In addition, the front and rear end portions of the conveyor are separated from each other by suspending an intermediate conveyor having a length substantially the same or partially overlapping between the opposite ends of the separated conveyor by a suspension stay. A load that is swingably disposed and supported and transported on the lower surface side of the separated conveyor is transported while being supported in a loading posture on an intermediate conveyor disposed between the separated conveyors. Thus, even if the conveyor separated by vibration such as an earthquake is displaced in the front-rear direction, the intermediate conveyor is also displaced in the front-rear direction, so that the load transportation line is not interrupted.

  Separating the middle of a conveyor for transportation between buildings or between buildings with a space of an appropriate length, facing the conveyor with separated front and rear ends above the separated conveyors An intermediate conveyor having a length overlapping with the end of the conveyor is arranged, and the load loaded on the upper surface of the separated conveyor is caught or suspended on the intermediate conveyor arranged between the separated conveyors. Since it was supported and transported in a posture, even if the separated conveyor is displaced in the front-rear direction due to vibration such as an earthquake, the intermediate conveyor does not interrupt the load transportation line. It becomes possible to resume the transport without any restoration work.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view schematically showing a conveyor-type transfer facility laid on the ceiling side with an example of the seismic isolation mechanism of the present invention, and FIG. 2 is a ceiling with another example of the seismic isolation mechanism of the present invention. FIG. 3 is a schematic side view for explaining an installation example of an intermediate conveyor in the seismic isolation mechanism of FIG. 1.

  In FIG. 1, 1 is the ceiling of one building Bu1, 2 is the ceiling of a building Bu2 that is different from the building Bu1, and 3 is a transport facility constructed between the ceilings 1 and 2 of both buildings Bu1 and Bu2. In the prior art, it was formed by a conveyor 3 penetrating between the ceilings 1 and 2 of Bu1 and Bu2 of both buildings.

  However, when the installation form of the rail 3 penetrating between the ceilings 1 and 2 is taken, for example, two buildings Bu1 and Bu2 are shaken by an earthquake, and the building Bu1 on one ceiling 1 is seismically isolated. If the building Bu2 on the other ceiling 2 has an earthquake-resistant structure, the modes of shaking of the ceilings 1 and 2 are completely different, and the rail 3 passing between the ceilings 1 and 2 is greatly deformed or damaged. There is a concern that it takes damage and takes a lot of time and effort to recover.

  Therefore, in the present invention, even if an earthquake situation such as the above is encountered, the entire conveyor-type transfer facility is not greatly damaged, and of course, the seismic isolation mechanism that can resume the operation of the transfer facility as it is after the earthquake has subsided Is incorporated into a conveyor-type transport facility. Hereinafter, this point will be described with reference to FIG.

  In the present invention, firstly, one conveyor 3 is separated in the vicinity of both buildings Bu1 and Bu2 with a separation distance L1 as an allowable seismic isolation amount, and divided into front and rear conveyors 31 and 32 to form a separating portion 4, An intermediate conveyor 5 is disposed above the separation conveyors 31 and 32 before and after the separation unit 4. The intermediate conveyor 5 has such a length that both side portions (front and rear end portions) can partially overlap with opposing ends of the separation conveyors 31 and 32. In addition, 31a, 32a, 5a is a stay for supporting each conveyor 31,32,5 suspended from the ceilings 1,2.

  The intermediate conveyor 5 is generally a little longer than the distance L1 (allowable seismic isolation amount) of the separating portions 4 of the conveyors 31 and 32 that are separated, but if the length is too long, the weight of the intermediate conveyor 5 is increased. This is not preferable in terms of the structural aspect such as an increase or a complicated structure, or in terms of conveyance efficiency. Therefore, as for the length of the intermediate conveyor 5, for example, when the container 6 having the total length m is located at the end (end portion) of the separation conveyor 31 or 32, the container 6 is about ½ of the length m. It is sufficient that the intermediate conveyor 5 has a length of about 1/2 m of the container 6 being transferred while being transported on the separation conveyor 31 or 32. In particular, as illustrated in FIG. 3, when the intermediate conveyor 5 is provided in a suspended manner on the cantilever type intermediate conveyor support frame 7 erected on either the separation conveyor 31 or 32, The length of the intermediate conveyor 5 is required to be as short as possible so that the weight is not bulky. Incidentally, the length L2 of the intermediate conveyor 5 illustrated in FIG. 3 is equivalent to or slightly larger than the seismic isolation allowance L1. Therefore, in the present invention, the intermediate conveyor 5 may have a length that is approximately the same as or overlapped between the front and rear ends of the separation conveyors 31 and 32.

  On the other hand, the distance H1 in the height direction between the upper surface of the intermediate conveyor 5 and the upper surfaces of the separation containers 31 and 32 is the height H2 of the container 6, more specifically, the container supported by the intermediate conveyor 5 from the bottom surface of the container 6. It is determined by the distance to the support part 6 (flange 6a in the example of the figure). The reason is that the container 6 that is carried on the upper surface of the separation conveyor 31 or 32 is supported by the conveyor 5 and transferred to the conveyor 5 at a portion supported by the intermediate conveyor 5 such as the flange 6a. Because it must be posted.

  An example of a conveyor-type transport facility incorporating the seismic isolation mechanism of the present invention is configured as described above. In a normal state where no earthquake or the like occurs, for example, the container 6 placed on the left conveyor 31 in FIG. Is conveyed to the right and approaches the intermediate conveyor 5, the container 6 is supported and conveyed by the intermediate conveyor 5 with the flange 6 a being locked to the intermediate conveyor 5 from below, and the end of the intermediate conveyor 5 is conveyed. 1 is transferred to the right side of FIG. 1 in the form of being transferred onto the separation conveyor 32 on the right side.

  However, even if an earthquake or the like occurs and the buildings Bu1 and Bu2 approach or separate from each other and the distance on the X axis in the plane between the buildings Bu1 and Bu2 changes, the amount of change is the allowable seismic isolation amount L1. Or within the range of overlap between the ends of the separation conveyors 31 and 32 and the end of the intermediate conveyor 5, the conveyance of the container 6 is not stopped by the action of the seismic isolation mechanism of the present invention. Can continue. Even if stopped, the conveyance can be resumed as it is. If the positions of the buildings Bu1 and Bu2 change in the Y-axis direction and the Z-axis direction, restoration work is performed.

  FIG. 2 schematically shows an example of the seismic isolation mechanism of the present invention applied to a transport facility in which the transport shape (support form) of the containers 6 of the separation conveyors 31 and 32 and the intermediate conveyor 5 is different from the example of FIG. .

  In other words, in the example of FIG. 1, the separation conveyors 31 and 32 are of the type in which the container 6 is placed and supported on the upper surface of the conveyor and conveyed, and the intermediate conveyor 5 is hooked and supported by the flange 6a of the container 6 for conveyance. In the example of FIG. 2, the separation conveyors 31 and 32 hook and support the flange 6a of the container 6, and the intermediate conveyor 5 places and supports the container 6 on the upper surface thereof for transport.

  As a result, the intermediate conveyor 5 is arranged at a lower position than the conveyors 31 and 32 in the separation unit 4 of the separation conveyors 31 and 32. In addition, the relationship between the conveyors 31, 32 and 5 in the length and height direction of the overlapping portions of the conveyors 31, 32 and 5, including the allowable seismic isolation amount L1 (distance of the separation unit 4) in the transport facility of FIG. Is basically the same as in FIG.

  In the seismic isolation mechanism of the present invention, the support by the suspension form of the container 6 of the intermediate conveyor 5 in FIG. 1 or the separation conveyors 31 and 32 in FIG. 2 is not limited to the hook support of the flange 6a, but other than the flange 6a. It may be a hook support or a suspension support of the part.

  In addition, the seismic isolation mechanism of the present invention is configured such that the intermediate conveyor 5 and the separating conveyors 31 and 32 before and after the intermediate conveyor 5 are arranged with a difference in the height direction, so that the separation portion 4 can be separated by an earthquake etc. Corresponding to the relative displacement of the conveyors 31 and 32 in the front-rear direction, there is no loss of function as a transport facility.

  Accordingly, the intermediate conveyor 5 and the front and rear separation conveyors 31 and 32 have a difference in installation in the height direction, and it is sufficient that the containers 6 to be transported can be continuously delivered by the conveyors 31, 5, and 32. The container support types of the conveyors 31, 5 and 32 are not necessarily different. For example, if the support position for the container 6 is varied in the height direction, the seismic isolation mechanism of the present invention can be formed even if the conveyors 31, 5, and 32 to be used are all of the container 6 hook support system.

The present invention is as described above, and the seismic isolation mechanism of the conveyor-type transport facility is separated in the middle of the transport conveyor erected between the buildings or between the buildings through a space of an appropriate length, An intermediate conveyor having a length substantially the same as or partially overlapping between the opposite ends of the separated conveyor is suspended by a suspension stay above the separated conveyors. A baggage which is arranged so as to be able to swing back and forth with respect to the separated conveyor and is carried on the upper surface of the separated conveyor is hooked or suspended on an intermediate conveyor arranged between the separated conveyors. It becomes so as to convey by supported, uninterrupted conveying line luggage by displacing the separate conveyors longitudinal also intermediate conveyor direction be displaced in its longitudinal direction by the vibration of an earthquake Even if the distance in the X-axis direction between buildings changes due to the influence of an earthquake, etc., the transport equipment will be used again without impairing the transport function and without requiring restoration work. It is extremely practical.
