[Industrial applications]
The present invention relates to a long object placing apparatus used for packing long objects such as cucumbers, carrots, yams, and long eggplants.
[0002]
[Prior art]
Conventionally, as a method of boxing cucumbers as in the above-described example, for example, as shown in FIG. 7, a large number of cucumbers K.. A large number of cucumbers K are sequentially placed on each of the concave placement portions Tb of the alignment tray T supplied to the feed-side end portion of the belt conveyor 60. After the placement, as shown in FIG. 5, each of the cucumber K ... placed on each of the concave placement portions Tb ... of the alignment tray T is sucked and held by each of the suction pads 32 ... constituting the cucumber box filling machine 6. Then, there is a method of packing in a cardboard box B.
[0003]
[Problems to be solved by the invention]
However, when a large number of cucumber K are continuously conveyed by the belt conveyor 60 as described above, even if the cucumber K brought in from the producer side is aligned straight and placed on the belt conveyor 60, Due to the occasional vibration, the orientation of each cucumber K placed on the belt conveyor 60 becomes disordered, and the cucumber K can be placed one by one on each concave placement portion Tb ... of the alignment tray T. Have difficulty. If a plurality of cucumbers K are placed at once in each of the concave placement portions Tb ... of the alignment tray T, the number of cucumbers K to be placed becomes excessive or insufficient, and immediately after placement. An extra cucumber K placed between the concave placement portions Tb of the alignment tray T is collected by a worker's hand, or is transferred to the recessed placement portion Tb of the alignment tray T which is fed empty. On the other hand, cucumber K must be replenished by the operator's hand, and human intervention is required to recover and replenish cucumber K. ing.
[0004]
In view of the above problems, the present invention drives a long object sorting means,Long objects conveyed by one conveyor line that constitutes a conveyor are transferred to another conveyor line.By distributing and supplying, there is no excess or shortage in the number of long objects to be placed, and many long objects can be reliably placed one by one on each long object mounting part.

Next, as shown in FIG. 3, a large number of cucumber K distributed on each of the charging conveyors 9 is placed on each of the concave placement portions Tb of the alignment tray T, and the same cucumber K is placed on the same. The cucumber K ... placed on each of the concave mounting portions Tb ... of the tray T is moved to the inclined side, and the front end of each cucumber K ... is placed on an alignment plate Tc formed at the longitudinal front end of the alignment tray T. Abut and align them horizontally. As shown in FIG. 4, after stopping the conveyance of each of the two aligning trays T, T at the aligning position on the circulating conveyor 2, the cucumber aligning machine 5 is driven and placed on the aligning tray T on the rear row side. The rear ends of the cucumbers K are brought into contact with an alignment plate Tc formed at the rear end on the longitudinal side of the alignment tray T so as to be aligned in a horizontal direction. At the same time, the cardboard box B placed on the box carrying conveyor 43 is conveyed to the lower part of the box packing position, the box elevating table 36 is vertically raised, and the cardboard box B assembled in a box form is supplied to the box packing position.
[0034]
Next, after stopping the transportation of the two alignment trays T, T at the alignment positions on the circulating conveyor 2, the cucumber box stuffing machine 6 is driven to drive the two alignment trays T, as shown in FIG. , T mounted on each of the suction pads 32... Are sucked and held by the suction pads 32, and are horizontally moved from the aligned position to the boxed position, and the 18 cucumbers K sucked and held by the suction pads 32. ... are gathered in the boxing interval. Immediately before packing, each flap Ba ... of the cardboard box B is opened by each of the four open plates 33 ..., and the cucumber K ... held by the suction pads 32 ... is stored in the cardboard box B at once. By releasing the adsorption, the boxing work of the cucumber K for one stage is completed. Similarly, the cucumber K placed on each of the alignment trays T, T in the next row is sucked and held by each suction pad 32, and is packed in a cardboard box B as appropriate.
[0035]
After packing a predetermined number of cucumbers K in a box, the box elevating table 36 is vertically lowered, the boxed cardboard box B is transferred to the box unloading conveyor 44, and the same cardboard box B is placed in the next step (for example, bag sealed). (Box process, box sealing process). Then, the cucumber arranging machine 5 and the cucumber box stuffing machine 6 are driven, and the cucumber K placed on each of the two alignment trays T, T is sequentially boxed into the next cardboard box B.
[0036]
As described above, a large number of cucumbers K conveyed by the respective feeding conveyors 9 are distributed and supplied to the conveyance lines on which the cucumbers K are mounted one by one with respect to each concave mounting portion Tb of the alignment tray T. Therefore, there is no excess or deficiency in the number of cucumbers K to be placed, and a large number of cucumbers K can be surely placed one by one on each of the concave mounting portions Tb... Of the alignment tray T. In addition, the labor and work of collecting the surplus cucumbers K and replenishing the insufficient cucumbers K as in the conventional method can be omitted, and the work of placing the cucumbers K having a peculiar shape can be performed mechanically. This eliminates the need for manual work intervention, reduces the number of workers, and saves labor and improves efficiency in mounting work.
