Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting machine for cutting off unnecessary stems and leaf tips prior to shipping harvested green onions, and to remove old peels and other deposits. That is, the present invention relates to a long green onion cutting / peeling machine and a control method therefor, which continuously perform a cutting process and a blowing process.

[0002]

2. Description of the Related Art The applicant of the present invention is a blow processing machine for removing old skins and deposits without relying on manpower in order to reduce the manpower dependence in the shipping work of the onion that has been harvested so far and to improve the shipping quality. Moreover, we have developed a cutting machine that removes unnecessary parts of the stem base and leaf tips that are not used for food. In other words, we have developed a machine aiming at labor saving, efficiency improvement of shipping work, and further improvement of shipping quality.

The automatic peeling machine disclosed by the present applicant in Japanese Utility Model Publication No. 64-5512 blows compressed air from the root side of the harvested long onion to the root side to remove old peels or adhered. It is a kind of cleaning machine that blows away dirt and sand. Further, the automatic cutting machine disclosed by the present applicant in Japanese Patent Application No. 7-150 relies on human beings for unnecessary parts of the base and leaf tips of long green onion, that is, parts of little utility value for food. Without the need for mechanical cutting. In particular, a feature of the cutting technique is that the cutting position at the base of the stem is appropriately positioned according to the size of the onion, that is, the cutting is performed so that unnecessary portions can be suppressed to the minimum.

However, as is well known, the above-mentioned automatic peeling machine using compressed air for removing unnecessary old skins and deposits, and the above-mentioned automatic cutting processor for the stem portion and the leaf tip portion are individually known. It is configured as a general processing machine. That is, it is individually configured as a single machine. Therefore, at least two machines must be prepared in order for the long green onion producer to carry out both the removal treatment of old skins and adhered substances and the removal treatment of the stem part and the leaf tip part before shipping. I was forced to leave. Therefore, purchasing and preparing two machines for a producer with a weak management base is a heavy burden and causes a high shipping cost, which is a bottleneck for the spread of the machines themselves.

Therefore, the applicant of the present invention, as in Japanese Patent Application No. 8-8886, uses a cutting machine for cutting off the unnecessary stem and leaf tips prior to the shipping of harvested long onion, old peels and the like. We proposed a long-green onion cutting and peeling machine that strips off the deposits, that is, cuts and blows continuously. This long green onion cutting and peeling machine has a conveying means for conveying the long green onion in a horizontal state,
Positioning means for determining the cutting position of the stem base portion according to the size of the onion, and cutting means for cutting the stem base portion and the leaf tip portion of the long green onion which is positioned by the positioning means and is conveyed by the conveying means. The present invention is roughly configured by a peeling means for blowing old air and other deposits attached to the onion, which has been cut by the cutting means, by blowing compressed air to blow it off.

[0006]

By the way, in the above-mentioned cutting and peeling machine for green onion, the set green onion is transferred by the transfer means, and the stem part and leaf tips of the onion are transferred by the cutting means. It is possible to cut the part and then blow off compressed old air and other deposits attached to the onion that has been cut by the peeling means to blow it away and process it continuously. One operator is required to set, and each cut green onion is grasped one by one, and the old peel and other deposits attached to the green onion are blown by blowing compressed air with a peeling means. One operator was required to perform the treatment (peeling treatment), and a total of two operators were required, and it was not possible to operate by one operator. Further, the operation mode is not configured to be switchable so that only one operator can continuously perform the cutting process only, or only the peeling process can be exclusively performed continuously so that only one operator can operate.

Further, when the cut onion is conveyed to the position of the peeling means, the conveying means is temporarily stopped, and the peeling means compresses old peels and other deposits attached to the peeling onion. When the blowing process (peeling process) of blowing and blowing air is completed, the conveying means is started after a certain waiting time, but when the operator becomes familiar with the peeling process work, the cutting process is performed. The long onions that have been cut off have to wait until they are conveyed to the position of the skin peeling means, and the waiting time is long, which is an impediment to operability and productivity.

In view of the above, the present invention makes it possible for two operators to carry out the cutting process and the peeling process of the onion in a continuous manner, and only the cutting process is dedicated so that even one operator can operate. The operation mode can be switched so that it can be continuously performed or only the skin removing process can be continuously performed, and the skin removing process can be smoothly performed according to the skill level of the operator. It is an object of the present invention to provide a cutting / peeling processing machine for long green onions and a control method thereof for solving the above-mentioned problems.

[0009]
