Description

[Detailed description of the invention] (a) Industrial application field This invention is based on, for example, weighing the total weight of fruits such as oranges and persimmons and other items packed in boxes in a cardboard box, The present invention relates to a boxing amount correcting device that is used for replenishing a box or the like having a predetermined boxing weight or less with an insufficient amount of fruits or the like.

(B) Conventional technology Conventionally, as a means for measuring the box body into which the oranges of the above-described example are put, for example, as shown in FIG. The container 2 is conveyed in the direction A, and at a calibration position C set in the middle of the conveyance of the roller conveyor 21, the weight of the box 2 is measured by the calibrator 22, and the total weight of the oranges K put into the box 2 is calibrated. Then, for example, two oranges K for a predetermined boxing weight
When the weight is insufficient, the worker F waiting at the calibration position C throws the mandarin K into the box 2 in a number corresponding to the insufficient weight.

(C) Problems to be Solved by the Invention However, at the calibration position C set during the conveyance of the roller conveyor 21, the total weight of the oranges K put into the box 2 in a large amount is measured. Until the work is completed, a large number of boxes 2 stagnate behind the box 2 stopped at the calibration position C, so that not only the box 2 requiring replenishment of the orange K but also the predetermined boxed weight is reduced. There is a problem in that the transfer processing of the box 2 having the same is also hindered.

In addition, since at least one worker F is required for the weighing and replenishment work, not only the labor required for the worker F but also the cost required for the boxing work is increased, and the weighing error of the worker F Also, there is a problem that the box 2 is shipped without being weighed.

(D) Means for solving the problem In this invention, a calibration position and a return position are set in the middle of a transport route for transporting a box, and these positions are connected by a detour route. Calibration means for weighing the total weight of the packaged articles put in a predetermined amount in the box at the calibration position, and extraction means for transferring only the underweight box to the detour path based on the calibration by the calibration means. Provided at the replenishment position of the bypass route, replenishment means for replenishing the box body with the insufficient weight of the boxed articles based on the calibration by the calibration means, and at the return position of the transport path, the replenishment means The present invention is characterized in that it is a boxing amount correcting device provided with a return means for transferring a box body replenished with a boxed item of insufficient weight to the transport path side.

(E) Function According to the present invention, the continuously conveyed boxes are individually calibrated by the calibrating means provided at the calibrating position of the transport path.
The total weight of the boxed articles put in a predetermined amount in this box is weighed. For example, if the weight of two boxed articles is insufficient for a predetermined boxing weight, based on the weighing by the weighing means, Then, the extracting means provided at the calibration position is driven to transfer only the box body with insufficient weight to the bypass route side.

Next, the box is conveyed along the bypass route, and the replenishing means provided at the replenishing position is driven based on the calibration by the calibration means, and two boxed articles corresponding to the insufficient weight are refilled into the box. After that, the return means provided at the return position is driven to transfer the box refilled with the boxed articles to a predetermined boxing weight to the transport path side, and to transport the box along the transport path.

(F) Effect of the present invention As described above, according to the present invention, only boxes having a weight equal to or less than the predetermined boxing weight are transferred from the transport route to the bypass route, and the quantity of the boxed items corresponding to the insufficient weight at the calibration position is reduced. When refilling a box, the shortage of a large number of boxes can be prevented from stagnating on the transport path, and a regular box having a predetermined boxing weight can be prevented. The body can be transported smoothly.

In addition, since the replenishing device is driven based on the calibration of the box by the detection means and mechanically replenishes the packaged articles in an amount corresponding to the insufficient weight, the calibration of the packaged articles put in the box, Insufficient weight can be reliably refilled in boxes, labor and calibration work can be saved, labor costs required for these works can be reduced, and shipping capacity can be increased.

In addition, a calibration means is provided at the calibration position of the above-described transport path, and a replenishing means is provided on the detour path whose starting end is connected to the calibration position, and the arrangement positions of the calibration means and the replenishing means are respectively set at different positions. Since the setting is performed, the transport direction of the regular weight box and the underweight box can be quickly separated (separated) into the transport route and the bypass route based on the calibration result by the above-described calibration means, and the weight can be reduced. There is an effect that only the insufficient box is conveyed to the bypass route, and the box having the insufficient weight can be appropriately replenished by the replenishing means of the bypass route.
