Conventionally, in a transfer plate loading device for placing a cutting work object on a transfer plate in a machine such as a cutting press and transferring the transfer plate directly below the cutting press, a rail is attached to the outside of the transfer plate and guides the rail. The rail guide is formed on the outside of the base top plate so that the rail of the transfer plate moves on the rail guide of the base top plate.

In such a configuration, the noise is severely generated by the friction of the rail and the rail guide during the transfer of the transfer plate, and as the number of transfers of the transfer plate increases, the rail and the rail guide wear out due to the friction of the rail and the rail guide. have.

In addition, since the inner side of the transfer plate has a fine gap with the base top plate, there is a problem that the transfer plate is bent as the number of cutting press operations increases. As such, when the cutting object is cut while the transfer plate is bent, a problem arises in that precise cutting is not made.

Therefore, there is a demand for the development of a new type of loading device capable of preventing warpage of the transfer plate without causing problems such as noise during transfer of the transfer plate.

Therefore, the present invention has been made in order to solve the above-mentioned conventional problems and to meet the above-mentioned conventional requirements, to suppress the occurrence of noise during loading and unloading of the transfer plate and to prevent the bending of the transfer plate due to press work. It is an object of the present invention to provide a loading device of a conveying plate floating type.

In this embodiment, the present invention is applied to a cutting press apparatus.

As shown in the drawings, the conveying plate floating type loading apparatus according to the present invention comprises a conveying plate 10 and the cylinder 20.

The transfer plate 10 is to mount the workpiece, the wheel 12 is provided on the four corners of the lower surface and the wheel 12 along the guide rail 32 formed on both outer sides of the base top plate 30 Move. At this time, the lower surface of the transfer plate 10 maintains a predetermined distance from the base upper plate 30.

The transfer of the transfer plate 10 is performed by the transfer gear 60 and the motor 60 and the belt 69 for forward and reverse rotation of the transfer gear 60. A coupling portion 66 is gear-coupled to the transfer gear 60, and an upper portion of the coupling portion 66 is fixed to a lower surface of the transfer plate 10.

Here, for example, when the motor 60 rotates forward, the turning power of the motor 60 is transmitted to the transfer gear 60 via the belt 69 to transfer the plate 10 fixed to the coupling part 66. To the cutting press 50. On the other hand, for example, when the motor 60 rotates in reverse, the reverse rotational power of the motor 60 is transmitted to the transfer gear 60 via the belt 69 to transfer the transfer plate 10 fixed to the coupling part 66. Move outward from the press 50.

In addition, the base upper plate 30 is provided with sensors 62 and 64 for detecting the position of the transfer plate 10 so that the transfer plate 10 is at an initial position outside or of the cutting press 50. Detect if it is located directly below.

The wheel lifting means is installed on the guide rail 32 corresponding to the wheel 12 of the transfer plate 10 when the transfer plate 10 is located directly below the cutting press 50, the cutting press 50 The wheel 12 is lowered during the cutting press operation so that the lower surface of the transfer plate 10 abuts on the base upper plate 30, and after the cutting press operation, the wheel 12 is raised to raise the transfer plate 10. The lower surface of the base plate 30 to maintain a predetermined interval.

When the wheel lifting means transfers the transfer plate 10, the upper portion 22 of the cylinder shaft maintains the same surface as the guide rail 32, and the transfer plate 10 is directly under the cutting press 50. The cylinder shaft is lowered in a state in which the lower surface of the conveying plate 10 and the base upper plate 30 abut, and when the cutting press operation is completed with respect to the object on the conveying plate 10, the cylinder axis is raised. It is preferable that the upper portion 22 of the cylinder shaft is constituted by the cylinder 20 so as to maintain the same surface as the guide rail 32.
