Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a nori cage holder transfer mechanism that automatically transfers nori cage holders between mutually independent transport mechanisms for nori cage holders in a nori manufacturing apparatus.

[Prior art and its problems]

In recent years, sheet nori has been mass-produced mechanically.

There are two types of machines for making this plate nori: fully automatic and semi-automatic.

For example, in a seaweed manufacturing device that manufactures sheet nori in a fully automatic manner, in the order of the seaweed processing steps, the sheet-making device,
A dewatering device, drying device, stripping device, and cleaning device are connected in circulation.

The production of plate nori using this nori production apparatus is carried out as follows. That is, in this device, a large number of seaweed cages are circulated and conveyed by the transport mechanism, and the seaweed is first made into sheets on the seaweed cages, then dehydrated, then dried for a predetermined period of time, and then dried. The dried sheets of seaweed are peeled off from the seaweed cage and made into products. Afterwards, the seaweed cage is washed and used for the next papermaking process.

In addition, the conveyance speed of the seaweed cage in the drying equipment is
In order to ensure sufficient drying time, the transport speed is slower than that in other parts, so the seaweed cages are transported by separate transport devices in both parts, and the seaweed cages are transferred between them.

Conventionally, the conveyance device in the drying equipment was formed by a blade chain, and the conveyance device for the main body of the machine for paper making was formed by a claw chain, and the transfer of the nori cage between both chains was carried out by crossing both chains. I was doing it. In this case, the structure around the chain to cross both chains becomes complicated, and the sprocket needs to be placed close to each other at the intersection of both chains, and the sprocket must be placed close to the dryer part and the machine body part. It was necessary to install a feather chain, etc.
