Description

[Detailed Description of the Invention] This invention relates to an improvement of a conveying device for conveying cylindrical objects such as rolled steel materials (round bars, pipes).

To explain the conventional conveyance device with reference to FIG. 1, 1 is a cylindrical object, 2 and 2' are chain transfers, and 3 is a walking beam for delivery provided at an intermediate position between the chain transfers 2 and 2'. 5 is the chain transfer 2,
On the loading platform 2', the cylindrical object 1 is loaded onto the loading platform 5 and transported to the X position by the chain transfer 2, and then transferred to the loading platform 5 at the Y position by the walking beam 3. It is designed to be conveyed in the direction of the arrow by a chain transfer 2'. Reference numeral 4 in FIG. 2 shows another conventional example of the above-mentioned delivery device, in which the cart portion runs on the floor in the direction of the arrow, while the loading platform moves up and down in the direction of the arrow to transfer the chain transfer of the columnar object 1. 2 to the chain transfer 2'. FIG. 3 shows another conventional example of the chain transfer 2, 2', in which a cylindrical object 1 is supported and conveyed by a rolling rail 6 and a rolling top roller 7. There is. FIG. 4 is an enlarged view of the loading platform 5 shown in FIGS. 1 and 2, in which the cylindrical object 1 is supported on the loading surface 5a of the loading platform 5 and conveyed. As mentioned above, there are two types of intermediate transfer devices: the walking beam system shown in Fig. 1 and the running trolley system shown in Fig. 2.
There are the loading platform method shown in the figure and the rolling method shown in FIG. 3, and these are arbitrarily selected depending on the surrounding conditions.

In the above-mentioned conveyance device, the () delivery device can only deliver a conveyed product in units of handling (one cylindrical object in FIGS. 1 and 2). () Furthermore, it is necessary to stop the chain transfers 2, 2' at the time of delivery, which takes time. () Chain transfer 2 as the original conveyance equipment,
In addition to 2', a delivery device is required, increasing equipment costs. () The downstream end of the chain transfer 2 in the conveyance direction and the upstream end of the chain transfer 2' in the conveyance direction are overlapped, and each chain transfer 2, 2' is driven synchronously to convey the If the products are directly transferred from the chain transfer 2 to the chain transfer 2', the transfer device becomes unnecessary and the problems of (), (), and () described above can be solved. However, when one of the chain transfers 2 and 2' is of the rolling type shown in Fig. 3, and the other is of the loading platform type shown in Fig. 4,
As shown in FIG. 5, when the conveyed article 1 is transferred, the loaded surface 5a of the loading platform 5 pushes the conveyed article 1 on the rolling rail 6, and the conveyed article 1 is moved between the conveyed article 1 and the loading surface 5a (see Z). ), which may cause damage to the conveyed product 1, which is undesirable.

This proposal addresses the above-mentioned problems by wrapping the downstream and upstream ends of the rolling type chain transfer and loading platform type chain transfer in the conveyance direction, and also In a conveying device that drives synchronously to convey a cylindrical conveyed product from one side of each chain transfer to the other, the above-mentioned loading platform type chain transfer has a conveying chain and a conveyor chain mounted on the conveying chain along the longitudinal direction of the chain. Each loading platform has wheels that roll on traveling rails, a top roller attached to the top of one end of the loading platform, and a loading platform that is tilted lower toward the top roller of the adjacent loading platform. The purpose of the conveyance device is to transfer a transfer from one of a rolling type chain transfer and a loading platform type chain transfer to the other. An object of the present invention is to provide an improved conveying device that can prevent damage to conveyed goods due to slips.

Next, the conveying device of the present invention will be explained using an embodiment shown in FIGS. 6 and 7. 11 is a loading platform with rollers;
The loading platform 11 with rollers has an inclined loading surface 12 on its upper part, and a pair of loading platform roller supports 13 are provided at the inclined upper end of the loading surface 12. A loading platform top roller 15 is rotatably supported. The conveyed article 1 is loaded onto the above-mentioned loading surface 12 and is configured to be supported by the loading platform top roller 15 of another adjacent loading platform 11 . Loading platform wheels 16 for supporting a load are rotatably attached to both ends of the loading platform 11 with rollers via wheel pins 17, and run on wheel rolling rails 18. There is. Loading platform with rollers 1
The traveling drive of No. 1 is achieved by attaching a loading platform mounting flange portion 19 provided at the bottom of the loading platform 11 with rollers and a special flange portion 22 provided at the top of the outer chain link 21 of the conveyance chain 20 using bolts and nuts 23. , by pulling the conveying chain 20. The conveyance chain 20 is
This is a chain with a special shaped attachment.
That is, the chain inner link 24 and the special flange 22
Additional chain outer links 21 are arranged alternately and connected by chain pins 25, and chain link rollers 26 are attached to the connecting portions.

Next, the operation of the conveyance device will be explained. Conveyed goods 1
is a loading platform 11 with rollers due to an inclined loading surface 12.
However, since the loading platform 12 of the roller-equipped loading platform 11 is inclined as described above, it is supported by the adjacent loading platform top roller 15.
It is transported in the pulling direction of the transport chain 20. The conveyed goods 1 are therefore not damaged when transferred from one chain transfer to another. Next, this point is shown in Figures 8 to 13.
This will be explained in detail with reference to the drawings. FIGS. 8 to 10 show the case where a conveyed article is transferred from a rolling type chain transfer on the left side to a loading platform type chain transfer on the right side. That is, (a) the conveyed article 1 on the rolling rail 6 is conveyed while being pushed by the rolling top roller 7 and rolling on the rail 6 (FIG. 8). (b) The rolling top roller 7 reaches the transfer section and sinks downward, but at this time, the conveyed product 1 on the rolling rail 6 is pushed by the loading platform top roller 15 and begins to be conveyed by rolling (Fig. 9) . (c) The article 1 transferred from the rolling rail 6 to the loading platform 11 with rollers is supported and conveyed by the loading surface 12 and the top roller 15 of the adjacent loading platform, and the transfer is completed (FIG. 10). In addition, FIGS. 11 to 13 are
This figure shows the case where a conveyed product is transferred from the loading platform type chain transfer on the right side to the rolling type chain transfer on the left side. That is, (a) the conveyed article 1 is supported and conveyed by the loading surface 12 of the roller-equipped loading platform 11 and the top roller 15 of the adjacent loading platform (FIG. 11). (b) From the loading surface 12 to the rolling rail 6
The conveyed product 1 transferred to the loading platform top roller 15
It is pushed and conveyed by rolling (Fig. 12). (c) The loading platform 11 with rollers reaches the transfer section and sinks downward, but at this time, the conveyed product 1 on the rolling rail 6 is pushed by the rolling top roller 7 and is conveyed by rolling,
The transfer is completed (Figure 13).

The conveying device of the present invention overlaps the transfer sections of the two chain transfers as described above, and drives them synchronously, eliminating the need for the transfer device and solving the problems of () () () above. However, in addition, the loading table type chain transfer is configured as described above, which has the effect of preventing slips that occur during delivery and preventing damage to the transported goods.
