Description

  The present invention relates to an adjustment technique provided in a conveyance system between a seismic isolation part and a non-base isolation part.

There are seismic isolation warehouses with seismic isolation parts in the whole warehouse or in a part of the warehouse. This seismic isolation warehouse is provided to prevent the collapse of cargo in a warehouse during a disaster such as a major earthquake by providing a seismic isolation structure to the storage racks in the entire warehouse or a part of the warehouse. Yes.
When delivering goods between such seismic isolation warehouses, deliver goods between general conveyors such as conveyors and traveling carts provided in the seismic isolation part and the non-isolation part. There is a need. Considering the shaking of the earthquake, it is not possible to directly connect the seismic isolation part to the non-isolation part. The part and the non-base-isolated part are configured so that they will not be damaged by direct contact even when the earthquake shakes.
This seismic isolation clearance is usually about 200 mm to 500 mm, and the clearance is larger than that of about 100 mm to 150 mm, which is a clearance between general conveying devices. This will hinder the delivery of articles between the installed conveyors.

  Therefore, in order to allow delivery of goods beyond the seismic isolation clearance, an expansion roller conveyor or a conveyor with a load feeder is installed between the seismic isolation part and the non-seismic isolation part. Conventionally, it has been possible to deliver articles.

JP 11-79347 A

However, in the seismic isolation countermeasure conveyor device of the above-mentioned Patent Document 1, since the entire seismic isolation countermeasure conveyor operates in the same manner due to the shaking of the earthquake, the seismic isolation countermeasure becomes large, and further, the seismic isolation part or the non-isolation part Because it is necessary to incorporate a seismic isolation device on the logistics equipment side, there is a problem that it is very time-consuming and expensive. In addition, the telescopic roller conveyor has a disadvantage that it can only carry articles with a small load of about 40 kg because the roller is attached to a scissor-type bracket. It cannot be applied at all between transport devices.
An object of this invention is to provide the conveyance mechanism for adjustment installed between the conveyor of a base isolation part, and the conveyor of a non-base isolation part.

The present invention is an interfacing system installed between a conveyor device provided in each of a seismic isolation part and a non-seismic isolation part, and includes a frame having two columns and an upper reed with a roller. A pair is provided in the transport direction, and the lower end installation part and the upper end installation part of the support are respectively pin-bonded, and elastic bodies that act inward of the frame are provided in the lower half and the upper half of the support, respectively. The frame support provided on the frame is provided with an approaching elastic body and a separating elastic body, and the support of one frame is provided in the seismic isolation part and the support of the other frame is provided in the non-isolation part. Features.
Further, the support column is connected to the pedestal, and the pedestal is provided with a stopper for regulating the tilting range of the support column.

The present invention has realized a transport mechanism for adjustment that is installed between a seismically isolated conveyor and a non-isolated conveyor that can operate smoothly during an earthquake.
According to the interworking system of the present invention, a frame with a simple configuration is configured by pin joining, and an elastic body, an approaching elastic body, and a separating elastic body are allowed to act on the frame, so that seismic isolation measures can be greatly increased. Therefore, it is possible to safely carry the article between the seismic isolation part and the non-seismic isolation part even at the time of an earthquake without taking time and effort. The support of the frame is connected to the seismic isolation part and the non-isolation part, and it can not be applied with a large load for installation, for example, it does not require a fixture such as a scissor bracket Therefore, the articles to be conveyed are not limited to those having a small load.
In addition, when a stopper that prevents the column from falling is provided, the angle of the column does not tilt beyond a certain level, so the conveyance surface itself does not tilt so as to drop the article being conveyed, and stable conveyance is achieved. It can be carried out.
When the column is installed through the pedestal, the column can be installed more easily. In addition, when the stopper is provided on the pedestal, since the space between the support column and the stopper can be set accurately, the interfacing system of the present invention can be installed more easily.

It is a front view of one Embodiment of this invention, Comprising: The movable range of a flame | frame is shown. It is a figure which shows the side surface of the normal state of one Embodiment of this invention. It is a figure which shows the side surface at the time of separation of one Embodiment of this invention. It is a figure which shows the side surface at the time of approach of one Embodiment of this invention.

The inter-working system of the present invention includes a frame having two support columns and an upper reed with a roller between a seismic isolation unit and a non-seismic isolation unit. Each frame is provided with an elastic body acting inward of the frame, and an approaching elastic body and a separating elastic body are provided on the support of the frame provided in the transport direction. The connection part of the frame employs pin joining.
Due to the functions of the pin joint and the elastic body, the frame is tilted due to an earthquake and is deformed such as separating and approaching.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.
FIG. 1 is a side view of an embodiment of the present invention, in which a pedestal 1 is provided on a base isolation floor 11 of a base isolation part and a non-base isolation floor 12 of a non-base isolation part. Further, the base isolation floor 11 and the non-base isolation floor 12 are each provided with a frame having an upper reed having two columns 2 and rollers 3. In this example, the lower end installation part of the support | pillar 2 is connected to the base 1 each installed in the seismic isolation floor 11 and the non-base isolation floor 12 by pin joining 13a, 13b. The roller 3 is rotatably provided on the upper reed.
The non-base isolation part is provided with a non-base isolation part conveyor 9 as a transport apparatus, and the base isolation part is provided with a base isolation part conveyor 10 as a transport apparatus. In the present embodiment, chain conveyors are used as the non-base isolation part conveyor 9 and the base isolation part conveyor 10.
The two frames are arranged between the non-base isolation part conveyor 9 and the base isolation part conveyor 10. As a result, the frame plays a role as a transfer device between the non-base isolation part conveyor 9 and the base isolation part conveyor 10. The upper reed and the upper installation part of the support column 2 are also connected by pin joints 14a and 14b, respectively.

  FIG. 2 is a front view of an embodiment of the present invention. At both ends of the pedestal 1, stoppers 4 are provided so as to sandwich the column 2. In addition, left and right regulating springs 6 that are elastic bodies acting inward of the frame are provided at the four corners of the upper and lower parts of the frame. The left and right regulating springs 6 are an upper left spring 61L that connects the upper reed and the left strut 2, an upper right spring 61R that connects the upper reed and the right strut 2, and a lower left that connects the floor and the left strut 2 The spring 62L is composed of a lower right spring 62R that connects the floor surface and the right column 2. As shown in FIG. 3 showing the movable range of the frame, the left and right regulating spring 6 (61L, 61R, 62L, 62R) exerts a force to return the frame to a rectangular shape.

  Returning to FIG. 1 again, on the side of the pedestal 1 where the support columns 2 are separated from each other, a spring receiving portion 5 that also serves as a stopper for preventing the support column 2 from falling too much is provided. A front-rear restricting spring 7 as a separating elastic body is provided between the support column 2 and the spring receiving portion 5. The column 2 and the seismic isolation floor 11 are connected to each other by 71a as the front / rear regulation spring 7 and 71b as the front / rear regulation spring 7 of the non-base isolation floor 12 respectively. A pulling spring 72 is provided as an approaching elastic body that pulls the struts 2 toward each other between the struts 2 facing each other.

Here, the operation of the interworking system in the present embodiment will be described.
First, as shown in FIG. 4, in the normal case, the goods or pallets as articles are delivered from the chain conveyor of the seismic isolation part or the non-seismic isolation part to the other chain conveyor via the intermediary system provided between them. Is done. At this time, the article moving between the seismic isolation part and the non-seismic isolation part is conveyed by the roller 3 of the room arrangement system. Since the floor arrangement system is fixed to the seismic isolation part and the non-isolation part via the pedestal 1 by the column 2, it is different from the telescopic roller conveyor attached via a scissors-type bracket or the like. Can be transported without any problem even if it is a heavy load.

Next, the operation during an earthquake will be described.
As shown in FIG. 5, when an earthquake force acts in a direction in which the seismic isolation portion and the non-isolation portion are separated from each other, the force acts in a direction in which the rollers 3 of both frames of the room arrangement system are separated from each other. At this time, the support 2 receives a force in the direction in which the roller 3 approaches due to the action of the pulling spring 72. As a result, the distance between the rollers 3 is larger than usual, but at the same time, the springs 71a and 71b are also moved relative to the support 2. Since the rollers 3 are not separated from each other too much, the gap between the chain conveyor and the roller 3 in the seismic isolation part and the non-isolation part is not increased more than necessary. The article does not fall between the rollers or between the rollers 3.
In addition, since the frame having the support 2 and the upper reed is pin-joined, and the support 2 and the pedestal 1 are also pin-joined, the pulling spring 72, the front / rear regulating spring 7, and the left / right regulating spring 6 Coupled with the action, the struts move smoothly during the earthquake, so that the article does not fall from the floor plan system due to vibration. Moreover, since the support | pillar 2 is not what was attached via fixtures, such as a scissors-type bracket, even when a heavy article is conveyed as an article | item, it can endure a heavy load.

  Further, as shown in FIG. 6, when an earthquake force acts in a direction in which the seismic isolation portion and the non-isolation portion approach, the force acts in a direction in which the rollers 3 approach each other. At this time, if the pulling spring 72 is bent and becomes shorter than the length in which no force is applied, the force of the pulling spring 72 causes a force in the direction of pulling the column 2, that is, the direction of pulling the rollers 3 together. Rather, the force that causes the rollers 3 to approach one of the chain conveyors in the direction of inclining the column 2 toward the respective chain conveyors is applied. At this time, the front / rear restricting springs 7 (71a, 71b) provided between the spring receiving portion 5 and the support column 2 also bend, but cannot bend more than a predetermined length. As a result, the front / rear restricting springs 7 (71a, 71b) ) Is sandwiched between the support 2 and the spring receiving part 5 so that the support 2 can be prevented from falling to the chain conveyor side of the seismic isolation part and the non-isolation part over a predetermined angle. As a result, the roller 3 comes into contact with the chain conveyor. Thus, the chain conveyor or the roller 3 can be prevented from being damaged. When the seismic force is applied in the direction in which the seismic isolation part and non-isolation part approach, the column 2 moves in the standing direction from the normal time, and the distance between the chain conveyors of the seismic isolation part and the non-isolation part approaches. Since the distances between the rollers 3 are close to each other, the article being conveyed does not fall. At this time, the frame having the support 2 and the upper reed is pin-bonded, and the support 2 and the pedestal 1 are also pin-connected. Therefore, the pulling spring 72, the front / rear restricting spring 7, the left / right restricting spring Since the movement of the column during the earthquake is smoothly performed in combination with the action of 6, the article does not fall from the floor plan system due to vibration.

Even when the seismic force works so that the heights of the seismic isolation part and the non-isolation part are different, the pulling spring 72 exerts the force in the direction that pulls the struts 2 toward each other, and the movement of the frame is smoothed by pin connection As a result, the gap between the rollers 3 is not increased more than necessary, and a certain inclination is provided from the high chain conveyor to the low chain conveyor via the roller 3 of the interposition system. Also, the articles being transported never fall.
If the seismic isolation part and the non-isolation part are shifted to the left and right, the chain conveyors do not face each other, and the seismic force acts in a direction that shifts to the left and right, the force of the left and right regulating spring 6 causes the support 2 and the roller 3 is constrained and deformed parallel to the left and right. For this reason, the roller 3 forms a conveyance path obliquely from one chain conveyor to the other chain conveyor. At this time, if the support column 2 tries to tilt more than a certain amount to the left and right, the stopper 4 and the support column 2 come into contact with each other to prevent the support column 2 from tilting further in the left-right direction. can do. In addition, because the left and right regulating spring 6 (61L, 61R, 62L, 62R) exerts a force to return the frame to the rectangular shape, the frame returns to the original rectangular shape as the earthquake attenuates. In addition, the left and right regulating spring 6 (61L, 61R, 62L, 62R) and the pin are smoothly operated by the pin connection. Therefore, there is no problem in the delivery of goods between the seismic isolation part and the non-seismic isolation part even during shaking.

  In an actual earthquake, not only the distance between the seismic isolation part and the non-isolation part changes, but also the height direction or only the left-right direction shifts. However, even if these movements occur at the same time, all the above-mentioned operations only occur at the same time. Therefore, the left / right regulating spring 6 (61L, 61R, 62L, 62R) and the front / rear regulating spring 7 (71a, 71b) The entire frame moves in conjunction with the action of the pulling spring 72, the stopper 4, and the spring receiving portion 5. At this time, since the frame is connected by pin joining, the chain conveyor between the seismic isolation portion and the non-seismic isolation portion Even when an earthquake occurs, the goods can be delivered without dropping the goods and the chain conveyor can be damaged even during an earthquake. The can be performed even without stable it. In addition, unlike the telescopic roller conveyor, the interlining system of the present invention does not require a large load for installation, such as a scissor bracket, so that it is large. It can handle loads, and can be manufactured and installed at a lower cost than a conveyor with a load feeding device or a conventional large-scale seismic isolation conveyor.

In the interworking system of this embodiment, the column is connected to the pedestal, and further, the pedestal is provided with a stopper that regulates the tilting range of the column. It can also be fixed to the floor of non-seismic isolation parts. Moreover, even if it is a case where a support | pillar is fixed using a base, it is good also as a structure which does not provide a stopper and a spring receiving part. It is also possible to provide a stopper and spring receiving part as a separate member from the pedestal. In this case, the column is directly fixed to the floor surface of the seismic isolation part and non-isolation part without using the pedestal. However, a stopper and a spring receiving part can be provided. The stoppers are not provided only on the left and right sides of the support but can be provided in a cylindrical shape surrounding the support so that the tilt angle of the support can be kept within a certain range regardless of the orientation.
In this embodiment, a chain conveyor is used as a transport device for the seismic isolation unit and the non-seismic isolation unit. It can be applied to belt conveyors, traveling carts, etc. as devices, and it is also possible to make each of them different without using the same type of conveying device as the conveying device provided in the seismic isolation part and non-isolation part. is there.

The technical scope is not limited to these embodiments unless specifically described to limit the present invention. That is, the above-described components in the embodiment of the present invention can be appropriately replaced with existing components and the like, and various variations including combinations with other existing components are possible.
