[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facility for collecting and shipping long products such as cucumbers, carrots, yams, and eggplants which are used for mechanically packing long fruits and vegetables.

[0002]

2. Description of the Related Art Conventionally, as a method of packing cucumbers as in the above example, for example, after sorting a large number of cucumbers brought in from a producer side by grade, a plurality of cucumbers of the same grade are used. There is a method in which a human operator holds the pieces one by one by hand and packs them in a cardboard box assembled in an open top form.

[0003]

[Problems to be Solved by the Invention] However, as described above, when a large number of cucumbers are boxed by a worker's hand, a large number of cucumbers brought in from the producer are packed in a box, so the boxing is performed. A plurality of workers are required for the work, and the packing work takes time and effort. In addition, there is a problem that the working efficiency per unit time is unstable because the working ability varies depending on the skill level of the worker.

There is also a method in which a large number of cucumbers are adsorbed and held by an appropriate suction means and packed in a box. For example, if the orientations and intervals of the cucumbers are not uniform, the cucumbers are adsorbed and held by the appropriate suction means. It is difficult to do this, and just before the adsorption, the direction and spacing of each cucumber must be adjusted by the operator's hand, and manual intervention is required. Is difficult.

In view of the above problems, the present invention can mechanically perform the entire operation from supply of long fruits and vegetables selected according to the class to packing, thereby saving labor and improving efficiency of the packing operation. The purpose of this facility is to provide a long collection and shipping facility.

[0006]

The long object collecting and shipping facility of the present invention is provided with a load receiving conveyor for transporting each of the containers in which the plurality of long fruits and vegetables are aligned and discharged to a discharge position on a transport path. At the discharge position on the conveyer for receiving
A long object discharging means for discharging each of the long fruits and vegetables put into each of the containers is provided, and a large number of each of the long sheets discharged by the long object discharging means are provided on a side of a discharging position on the conveyer for receiving goods. Separation conveyors for separating and conveying fruits and vegetables at appropriate intervals are provided, and a number of long fruits and vegetables formed in such a size that a predetermined number of long fruits and vegetables are arranged in parallel at the lower end of the separation conveyor. A long conveyor is provided to supply the long object aligning table, and each of the long object aligning tables is moved from the input position on the circuit path to the aligning position, and the respective long objects are arranged at the aligning position on the circular conveyor. A long object collection and shipping facility provided with a long object box packing means for adsorbing and holding a predetermined number of each long fruit and vegetable placed on the object sorting table with a suction pad at box packing intervals and packing the inside of the box. It is characterized by.

[0007]

The long object collecting and shipping facility of the present invention sequentially transports each container, in which a large number of long fruits and vegetables are lined up and arranged, to the discharge position on the receiving conveyor, and drives the long object discharging means. A large number of long fruits and vegetables put in each container are sequentially discharged onto a separation conveyor. A large number of long fruits and vegetables released on the separation conveyor are aligned and transported at appropriate intervals while being separated at appropriate intervals. The long fruits and vegetables of the number are sequentially transferred. Each long object aligning table is sequentially moved from the loading position on the orbiting conveyor to the aligning position, and the long object box packing means is driven, and a predetermined number of each length aligned and mounted on each long object aligning table is driven. Suction of fruits and vegetables with suction pads
Since the clothes are held and packed in the box, no human intervention is required.

[0008]

[Effect of the Invention] According to the invention, the long fruits and vegetables selected according to the rank are separated at appropriate intervals, transferred to the long object sorting tables, and aligned on the long object sorting tables. Each of the long fruits and vegetables is transported and supplied to the long object box packing means while being placed, so that the labor and work of packing the long fruits and vegetables by the operator's hand as in the conventional example can be omitted, and the long fruits and vegetables can be removed. There is no need to align the directions and the intervals. Since there is no need for human intervention, the entire operation from the supply of long fruits and vegetables to the packing of boxes can be performed mechanically, and the labor and efficiency of boxing can be reduced. In addition, the packaging unit price is lower than in a box packing method in which a predetermined number of long fruits and vegetables are packaged together in a packaging container or the like, and the time required for the box packing operation and the packaging cost can be reduced.

The illustrated embodiment is configured as described above, and the boxing operation of the cucumbers K by the cucumbers collection and shipping facility 1 will be described below. First, as shown in FIGS. 1 and 2, a large number of each of the transporting containers C brought in from the producer side are sequentially transported to the rollover position on the conveyer 2 for loading, and at the same time, the container rollover machine 3 is driven. And two transport containers C,
Conveyor 4 for separating many cucumbers K put into C
Release all at once. The released empty containers C are transported and supplied to a recovery step (not shown).

Next, a large number of the cucumbers K discharged onto the separation conveyor 4 are arranged and transported in two rows while being separated at appropriate intervals in the front-rear direction, and are arranged side by side at the lower end side of the separation conveyor 4. A large number of cucumbers K are transferred one by one between the respective feed rollers 10 of the respective roller conveyors 7. At the same time, each of the plurality of alignment trays T... Is transported one by one to a loading position on each of the circulating conveyors 5, 5 arranged side by side at the lower end side of each of the roller conveyors 7, 7. Each cucumber K supplied from 7, 7 is supplied to each shooter 11, 1
Each of the concave mounting portions Tb of the alignment tray T, which is guided to fall by 1 and is conveyed to the loading position on each of the circulating conveyors 5 and 5,.
Are transferred one by one.

Next, each of the alignment trays T is connected to a corresponding one of the guide plates 5e, 5e provided in the middle of the path on each of the circulating conveyors 5, 5.
Are turned by 90 degrees, and the two alignment trays T, T are conveyed to the alignment positions on the circling conveyors 5, 5, respectively. As shown in FIG. 3, when the conveyance of the two alignment trays T, T is stopped immediately before the alignment position on each of the circulating conveyors 5, the cucumber aligners 45, 45 are driven, respectively.
