[Industrial applications]

 The present invention relates to an upside-down device for a box for storing a seaweed bundle, which is used to turn the box containing the seaweed bundle upside down and take out the seaweed bundle from the box.

[0002]

[Prior art]

 The sheet-shaped dry seaweed produced by the dry seaweed production apparatus is folded into two by a predetermined number by the binding means disclosed in, for example, Japanese Utility Model Laid-Open No. 62-33502, and is bound by a tape into a box such as a cardboard box. It is stored and then shipped to fisheries cooperatives.

Dry seaweed brought into a fishery cooperative or the like is shipped to the market after quality inspection. This quality inspection is performed as follows. That is, open the top lid of the box containing the seaweed bundle, turn this box upside down on the table, and take out the inner seaweed bundle onto the table.

Next, this seaweed bundle is placed on a conveyor. An inspection machine such as a metal detector or a weighing machine is installed on the conveyor conveyance line. While conveying the seaweed bundle by the conveyor, the metal detector inspects whether the seaweed bundle contains metal pieces. In addition, the seaweed bundle is inspected with a weigher to see if it has the prescribed weight. The inspector then visually inspects the color of the dried nori to determine the grade of the dried nori.

[0005]

[Problems to be solved by the device]

 The number of boxes mentioned above that are brought into one fishery cooperative is extremely large, and may exceed 1,000 boxes per day. The box weighs about 15 kg, which is quite heavy. In this way, it is extremely hard work to turn over a large number of heavy boxes upside down and take out the seaweed bundles stored inside them into a table.

[0006] Therefore, an object of the present invention is to provide an upside-down device for a seaweed bundle storage box, which can turn the box containing the seaweed bundle upside down and easily take out the seaweed bundle onto a table or the like. To do.

[0007]

[Means for Solving the Problems]

 For this reason, the present invention uses the conveyors 4 and 5 that convey the box 1 containing the seaweed bundle 2 to the upside-down station S, and the sensor 7 that detects that the box 1 has been conveyed to the upside-down station S. At this upside-down station S, the cover member 15 that closes the opened upper surface of the box 1 and the support member 36 that supports the box 1 and the sensor 7 are conveyed to the upside-down station S. If this is detected, the cover material 15 and the up / down reversing mechanism 31 to 34 for reversing the box 1 by rotating the support member 36 in the up / down direction constitute the up / down reversing device for the seaweed bundle storage box. It is a thing.

[0008]

[Action]

 In the above configuration, when the box 1 containing the seaweed bundle 2 is placed on the conveyors 4 and 5, the box 1 stops at the upside down station S. Next, by operating the upside down mechanisms 31 to 34, the box 1 is lifted upside down by the support member 36 while the upper surface of the box 1 is closed by the cover member 15, and is transferred upside down on the table 37 or the like. Next, when the box 1 is pulled up, the seaweed bundle 2 inside is taken out onto the table 37.
