Abstract

PURPOSE:To securely mount a number of long size articles one by one on respective mounting zone for long size articles without excess or shortage in the number of long size articles, by distributing and supplying a number of long size articles into transfer lines placed one by one on respective mounting zones by driving a long size article-distributing means. CONSTITUTION:When a cucumber K is not placed in the recessive mounting zone Tb of a lining-up tray T transferred to the mounting position on a circulating conveyor, a CPU judges that there is no cucumber K on the basis of the detected signals output from respective photoelectric sensors Sc of the third sensor group S3. And at the same time, the mounting timing of recessive mounting zone Tb which has been judged as no-load and respective cucumbers K transferred by respective feed conveyors 9 is calculated on the basis of the detected signal output from the respective photoelectric sensors Sa of the first sensor group S1. And respective opening or closing cylinders of the third cylinder group are opened and the respective distributing plates 45 of the first distributing plate group and the respective distributing plates 48 of the second distributing group are actuated to supply a cucumber to the recessive mounting zone Tb judged as no-load.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a long object placing apparatus used for packing long objects such as cucumber, carrot, potato, and eggplant.

[0002]

2. Description of the Related Art Conventionally, as a method of packing cucumbers as in the above example, for example, as shown in FIG. 7, a large number of each cucumber K ... Then, a large number of cucumbers K ... are sequentially mounted on the concave mounting portions Tb ... Of the alignment tray T supplied to the end portion on the feed side of the belt conveyor 60. After mounting, as shown in FIG. 5, each concave mounting portion Tb of the aligning tray T is formed by each suction pad 32 ... Which constitutes the cucumber box packing machine 6.
There is a method of adsorbing and holding each cucumber K ...

[0003]

However, when a large number of cucumbers K ... are continuously conveyed by the belt conveyor 60 as described above, the belt conveyors 60 are arranged so that the cucumbers K. Even when the cucumbers are placed on the top, the orientation of the cucumbers K ... Placed on the belt conveyor 60 becomes disordered due to the vibration generated during the conveyance, and the cucumbers K are placed on the concave placement portions Tb ... of the alignment tray T. It is difficult to place one by one. If a plurality of cucumbers K ... are simultaneously mounted on the concave mounting portions Tb ... of the alignment tray T, the number of cucumbers K to be mounted will be excessive or insufficient, and immediately after the mounting. , Each of the concave mounting portions Tb of the alignment tray T ... Collects extra cucumber K placed between them by a worker's hand, or to the concave mounting portion Tb of the alignment tray T that is fed in an empty manner. On the other hand, the cucumber K must be replenished by the operator's hand, and the intervention of human work is required to collect and replenish the cucumber K, which causes a problem that the placing work is troublesome and time consuming. ing.

In view of the above problem, the present invention drives a long object allocating means to distribute a large number of long objects to a conveyor line which is placed one by one for each long object placing section. By supplying, there is no excess or deficiency in the number of long objects to be placed, and it is possible to reliably place a large number of each long object one by one on each long object placing section. The purpose is to provide a mounting device.

[0005]

SUMMARY OF THE INVENTION According to the present invention, the long object is placed or not placed on each of the long object placing portions supplied to the feed-side end portion of the conveyor. A long object detecting means for detecting whether or not there is one, and a large number of each long object conveyed by the conveyor for conveyance are placed on the conveyor line for placing one long object on each long object placing section. When it is determined that the long object is not placed on the long object placing portion based on the detection by the long object allocating means for distributing and supplying the long object, the long object allocating means It is characterized in that it is a long object placing device provided with a distribution control means for driving the means.

[0006]

According to the present invention, based on the detection by the long object detecting means, the long object is placed or not placed on each long object placing portion supplied to the feed side end of the conveyor. It is determined by the distribution control means whether it is a storage device. When it is determined that the long object is not placed, the long object allocating means is not driven, and the long object conveyed by the conveyer for the conveyor is supplied to the transfer line which is determined not to be placed. When it is determined that the long object has been placed, the long object allocating means is driven to distribute and supply the long object conveyed by the conveyor for conveyance to the conveyance sign that is determined not to be placed. A large number of each long object can be placed one by one on each long object placing portion.

[0007]

According to the present invention, a large number of each long object conveyed by the conveyor for conveying is distributed and supplied to the conveyor line in which one long object is placed on each long object placing section. Therefore, there is no excess or deficiency in the number of long objects to be placed, and a large number of each long object can be reliably placed one by one on each long object placing portion. Moreover, it is possible to save the trouble and work of collecting the surplus long object and replenishing the short object like the conventional method, and to mount the long object having the unique shape on the machine. Since it can be performed automatically, it is possible to reduce the number of workers by eliminating the need for human intervention, and to reduce the labor and efficiency of the placement work.
