Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a metal plate loading device, and more specifically, the present invention relates to a metal plate loading device, and more specifically, a metal plate loading device for transporting sheet metal plates packed in boxes or loaded on a loading platform. The present invention relates to a metal plate loading device used as a device for loading and unloading onto a conveyor, for example, or as a bailer for stacking the metal plates from the conveying means onto a loading table or packing them into boxes.

<Prior art> Conventionally, boxed or stacked sheet metal plates are processed through continuous processing equipment, such as continuous plating equipment, continuous pickling equipment, continuous coloring equipment, and conveyance means of processing lines such as pressing and shearing. For example, there are many types of metal plate loading devices, such as depilers that load and unload metal sheets onto a conveyor, or metal plate loading devices that are used as foilers that unload metal sheets from a conveyor after processing, stack them on a loading platform, or pack them into boxes. These can be roughly divided into devices that use the following two methods.

First, the first device is a device in which a suction cup is placed over the entire surface of a metal plate, the entire surface of the metal plate is suctioned by the suction cup, and the metal plate is moved to a predetermined position.

An example of such a loading device is shown in FIG. 3a. As shown in FIG. 3a, the loading device 10o can be used both as a bailer and as a depiler, but the case where it is used as a depiler will be described as an example. When used as a device, the loading device 100 loads and unloads the metal plates 106 stacked on loading tables 104 and 104 disposed on both sides of the processing line 102 onto a conveying means 108 such as a roll conveyor of the processing line 102. processing line 102

The suction cup 114 was lowered, removed, and placed on the roll conveyor or belt conveyor of the conveying means 108. At this time, in order to prevent the metal plate 106 from falling during transportation, suction cups were placed at multiple positions on the entire surface of the metal plate 106 to strongly adsorb the metal plate 106, as shown in FIG. 3b. In this way, the metal plate 106 was transferred from the position shown in Figure 3b to the position shown in Figure 3c.

Japanese Patent Publication No. 51-45145 discloses a metal plate loading device using the suction transfer method, which is capable of controlling the pressure inside the suction cup to prevent objects to be transferred such as metal plates from falling during transfer. An object transport device is disclosed.

In addition, in order to ensure that one sheet of metal plate
-Publication No. 61543 discloses that the suction device placed on the edge of the metal plate is lifted first, the ends of the first and second sheets are separated, and the remaining suction devices placed on the entire metal plate are lifted. A method for reliably separating only the first sheet is disclosed.

Next, another second device, as shown in FIG.
Using a permanent magnet as a sorting magnet (e.g. floater 120), floating using the repulsion of the magnetic metal plate 106,
The tip of the metal plate 106 is suctioned by the suction cup 114, lifted up by the elevating means 116, the traveling cart 112 is moved on the frame 110, the metal plate 106 is completely placed on the conveying means 108, and the conveying means 108 moves the metal plate 106 to the processing line. 10
