Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a carrier device used for transferring an object such as a car body between an upper carrier type carrier device and a lower carrier type carrier device. The present invention relates to a transfer device.

2. Description of the Related Art Conventionally, as an apparatus of this type, for example, the actual construction of Shokai 63-77914 is used.
The structure found in the publication is provided. That is, in this conventional structure, a pair of columns arranged in parallel are provided with lifting bodies, respectively, and a common lifting drive device that interlocks with these lifting bodies. An article support member is provided on each lifting body via an arm.

According to this conventional structure, the articles conveyed through the hanger by the upper overhead conveyor are supported on both sides by the article support members by the elevation of the elevating body, and both elevating bodies are lowered after the hanger retreats. Goods are handed to the lower floor conveyor.

According to the above-mentioned conventional structure, a large bending moment acts on each of the two arms, and in order to withstand the large bending moment, the arm, the lifting body, the column, and the like must have a strong structure, which leads to an increase in size. It is also possible to make the left and right lifting bodies rigid with an intermediate frame, but this allows the accuracy of the standing pitch of both struts, the standing accuracy (tilt) of both struts, and the amount of extension of both chains in the lifting drive device to be increased. Due to a step or the like between the two lifting bodies due to the difference, the movement (rolling) of the guide roller on the lifting body side with respect to the guide rails on both the support columns becomes a catching or clogged shape, and the lifting and lowering side cannot be smoothly moved.

Therefore, recently, both ends of the intermediate frame are connected to both elevating bodies via a pair of upper and lower horizontal pins and links, respectively, or one end of the intermediate frame is vertically swingable to one elevating body via the horizontal pins. There is provided a structure in which the other end is connected to the other elevating body so as to be vertically swingable and slidable in the side by side direction via a roller.

Problems to be Solved by the Invention Among the above-mentioned conventional structures, in the structure in which each of the four horizontal pins is connected through a link, since each of the four horizontal pins is a swinging pivot fulcrum, it is easy and large in the parallel arrangement direction of the columns. It will shake, especially when going up and down. In the latter sliding type, it is difficult to assemble at the site because the roller is fitted into the long hole in the side-by-side direction formed on the side of the lifting body, and therefore it is easy to transport from the factory to the site. Absent.

An object of the present invention is to provide a transfer device between transfer devices that can be assembled on site and can reduce shaking while using an intermediate frame to cope with a bending moment.

Means for Solving the Problems In order to achieve the above-mentioned object, a transfer device between transfer devices according to the present invention is a transfer device between transfer devices for transferring an object to be transferred between an upper transfer device and a lower transfer device. A device,
Elevators are provided on a pair of columns that are arranged side by side, a common lifting drive device that interlocks with these elevators is provided, and an intermediate frame is provided between both elevators. A hinge with a link, which is swingably connected via a hinge having a horizontal axis that is orthogonal to the side-by-side installation direction and has a pair of upper and lower horizontal axes parallel to the horizontal axis and a link, is provided on the other lifting body. The intermediate frame is provided with a delivery tool for the transported object.

According to the configuration of the present invention, by raising and lowering both the lifting and lowering bodies integrated by the intermediate frame by the lifting and lowering drive device, it is possible to receive the object to be transported which has been transported by the upper transporting device by the transfer tool, and both the lifting and lowering bodies. By lowering
The transported object can be passed to the lower-level transport device. Further, by the opposite action, the object to be conveyed which has been conveyed by the lower conveying device can be transferred to the upper conveying device. In such an operation, since both the lifting bodies are integrated by the intermediate frame, it is possible to cope with bending moment while being compact. Further, when ascending / descending, swinging of the link in the hinge with a link can cope with a change in the pitch of the two support posts arranged side by side, and can also cope with a step difference between both the ascending / descending bodies due to extension of the chain. In addition, the swing of the intermediate frame can be small because one hinge has no links. Since both hinges can be easily fixed to the lifting body or the intermediate frame with bolts or the like, assembly at the site can be easily performed.

The bracket 47 is fixed to the other end of the intermediate frame 35 by a bolt 48 or the like. Therefore, the intermediate frame 35 and the other lifting body 27B are located at the upper left-right axis 49
And a lower left-right axis 50 are swingably connected. The intermediate frame 35 is provided with a delivery tool 52 for the vehicle body 9. The delivery tool 52 is a pair of front and rear forks, and a receiving portion 54 that supports the lower surface of the vehicle body 9 is provided on the upper surface of the final stage actuating member 53. You can move in and out freely.

In the transfer device 21 described above, the intermediate frame 35 is a support column 23A,
It is separated from the 23B and transported from the factory to the site. At the site, the columns 23A and 23B are erected, the upper frame 24 is connected, and the lifting body 2
7A and 27B are attached. A hinge 36 and a hinge 42 with a link are attached to the lifting bodies 27A and 27B.
Then, the bracket 39 of the hinge 36 is connected to one end of the intermediate frame 35 with a bolt 40, etc.
The entire assembly can be performed by connecting the bracket 47 of 42 to the other end of the intermediate frame 35 with a bolt 48 or the like.

Next, using the transfer device 21 assembled as described above, the operation of transferring the vehicle body 9 conveyed by the upper carriage type carrier device 1 to the lower carriage type carrier device 11 will be described.

When the working member 53 of the delivery tool 52 is retracted, the trolley 5 supporting the vehicle body 9 of the upper trolley-type carrier device 1 is stopped facing the transfer device 21. In this state, the transfer tool 52 is operated, and the operating member 53 is projected between the support tools 6 and below the vehicle body 9. Next, the elevating drive device 28 is operated to raise the intermediate frame 35 together with the elevating bodies 27A and 27B, and the vehicle body 9 is lifted via the receiving portion 54. Then, the delivery tool 52 is reversely operated to position the vehicle body 9 between the columns 23A and 23B. At this time, in the lower carriage type carrier device 11, the empty carriage 15 is stopped facing the transfer device 21. Next, the intermediate frame 35 is lowered together with both the lifting bodies 27A and 27B to lower the vehicle body 9 to a predetermined level. Then, the delivery tool 52 is moved so as to project, and the vehicle body 9 is positioned above the reception tool 16 of the carriage 15. In this state, the delivery tool 52 side is slightly lowered, and the vehicle body 9 is delivered onto the delivery tool 16 of the carriage 15. After that, the transfer tool 52 moves back and forth, and the carriage 15 supporting the vehicle body 9 is moved to the next process.

In the transfer device 21 for transferring the vehicle body 9 as described above, when the accuracy of the arrangement pitch of the columns 23A and 23B, that is, the guide rails 25A and 25B is poor, or both columns 23A and 23B are installed upright. When the lifting and lowering operations are performed, the two lifting bodies 27A and 27B try to approach or separate from each other, which can be absorbed by the inward swing of the link 45 with respect to the flange 43. , Therefore the guide rail 25
As the rollers 26A, 26B are guided to A, 25B,
It is performed smoothly without getting stuck or caught.
Also, due to the change in the amount of extension of both chains 33A and 33B, both lifting bodies 2
When a step in the up-down direction occurs between 7A and 27B, this means that the intermediate frame 35 swings up and down relatively with respect to the lifting bodies 27A and 27B about the left-right axis 41, 50, respectively. It can be absorbed by the swing of the link 45, and the lifting and lowering can be performed smoothly. Although the intermediate frame 35 tries to swing during such lifting and lowering, one of the hinges 36 does not have a link, so a brake is applied to the swing.
Therefore, the swing can be reduced. Both lifts 27A, 27B
Since the intermediate frame 35 and the intermediate frame 35 are integrated, it is possible to sufficiently cope with the bending moment while being made compact.

In the above embodiment, the flanges 37 and 43 of both hinges 36 and 42 are used.
The intermediate frame 35 is connected to the intermediate frame 35 by bolts 40 and 48, but this may be welded locally or a combination of bolt-up and welding. Further, in the above-described embodiment, the trolley-type carrier devices 1 and 11 are shown for both the upper and lower layers, but a suspended carrier device may be adopted as the upper-layer carrier device, for example.

Effect of the Invention According to the present invention having the above-described configuration, after the pillars are erected at the site and the lifting body with the hinges is assembled, the intermediate frame is connected to both hinges by bolts or welding, so that the transfer device can be installed. Assembly can be done easily on-site, and therefore transportation from the factory to the site is easy. By the ascending / descending movements of both the lifting and lowering bodies which are assembled in this way and integrated by the intermediate frame and the operation of the transfer tool, it is possible to transfer the transferred object between the upper transfer device and the lower transfer device. . At this time, since both the lifting bodies are integrated by the intermediate frame, the bending moment can be sufficiently dealt with while being compact, and the overall size can be reduced. Furthermore, as for the vertical movement, the link structure of the flanges with links can be swung to accommodate changes in the pitch of both columns and tilted uprights. With the link swing structure described above, it is possible to cope with a step in the vertical direction generated between the two lifting bodies, and as a result, lifting and lowering on the lifting body side can always be performed smoothly without being caught or clogged. Further, when the intermediate frame is moved up and down, one hinge does not have a link, so that the swing can be reduced.
