Description

  The present invention relates to a storage device for dropping stored items such as potatoes into a storage box by a discharge conveyance mechanism such as a vertical conveyor.

2. Description of the Related Art A storage material input device that stores an object such as a potato in a storage box such as a shipping container is used.
The stored item charging device includes a vertical conveyor (slide loader) having an endless body that is driven endlessly in the vertical direction with the lower end facing the opening of the storage box.

  In addition to the endless body, the vertical conveyor includes a plurality of support members arranged in series along the transport direction on the endless body, and from a main transport mechanism that lifts and transports stored items to a predetermined height position. The stored item is inherited by the support member directly or via a relay transfer mechanism, and the stored item supported by the support member is transferred toward the lower end portion according to the downward movement of the endless body, and the lower end According to the direction change of the endless body in the section, the stored item supported by the support member is dropped and discharged into the storage box.

  In order to reduce the impact applied to the stored items when the stored items discharged from the vertical conveyor are dropped into the storage box, the stored item charging device has the following configuration.

  The vertical conveyor is movable in the vertical direction, and the storage device is further provided with an elevating mechanism for moving the vertical conveyor in the vertical direction, and a height of a stack of stored materials stored in the storage box. And a control device that controls the operation of the elevating mechanism.

  The control device, based on a signal from the height sensor, when the distance between the position of the lower end of the vertical conveyor and the upper end of the deposit of stored items stored in the storage box is less than a predetermined distance, The elevating mechanism is operated so as to raise the vertical conveyor by a predetermined distance.

  The conventional stored item throwing apparatus having such a configuration can effectively reduce the impact when the stored item lands by suppressing the fall distance of the stored item discharged from the lower end of the vertical conveyor. Although useful in terms of being able to be made, there were the following disadvantages.

That is, in the conventional storage device, the relative position of the vertical conveyor with respect to the storage box in the plan view (the horizontal relative position of the vertical conveyor with respect to the storage box) is fixed. The discharged stored items are accumulated in a mountain shape with the vicinity immediately below the lower end of the vertical conveyor as a vertex, and it is likely that the entire storage space of the storage box cannot be used effectively.
In particular, the problem increases as the storage box becomes larger.

  In this regard, for example, Patent Document 1 below includes a conveyor that conveys the stored item obliquely upward and discharges the stored item obliquely upward along the conveyance direction at the conveyance end portion, and is discharged from the conveyor. Storage device for storing the stored material in a storage box installed below, the storage material input configured to cause uneven speed in the peripheral speed of the rotary transmission element that moves the endless body in the conveyor A device has been proposed.

  In the storage device throwing device described in Patent Document 1, the discharge speed of the storage material discharged from the conveyance terminal portion of the conveyor is changed according to the change in the peripheral speed of the rotation transmission element, thereby storing the storage material. It is supposed that the fall position in the box is changed to prevent the stored items from being deposited locally in the storage box.

However, in practice, it is very difficult to cause the endless body moving speed to change as the fall position of the stored item varies depending on the peripheral speed change of the rotation transmission element.
Moreover, the structure of the said patent document 1 has the horizontal direction component in the moving speed of the stored matter discharged | emitted from the said conveyor, ie, the said conveyor is a horizontal direction (it includes diagonally upward or diagonally downward). It is a precondition that it is transported to a storage device, and cannot be applied to the stored material input device having the vertical conveyor.

  The control device first positions the first drop position changing means 100 (1) at a reference position (see FIG. 4) around the pivot shaft 105 (step S1), and the first displacement side vertical distance is a predetermined distance. It is determined whether it is less than that, that is, whether or not an appropriate amount of storage has already been put in the first displacement position (step S2).

  In the case of NO in step S2, that is, when there is an empty space at the first displacement position, the control device causes the first drop position changing means 100 (1) to be positioned at the first guide position. The moving mechanism 150 is operated to drop the stored items discharged from the first vertical conveyor 11 (1) to the first displacement position (step S3), and the process returns to step S2.

  The control device maintains this state until the determination in step S2 becomes YES, that is, until there is no free space at the first displacement position.

  In the case of YES in step S2, that is, when there is no free space at the first displacement position, the control device determines whether or not the second displacement side vertical distance is less than a predetermined distance, that is, there is a stored item at the second displacement position. It is determined whether or not an appropriate amount has already been charged (step S4).

The moving mechanism 150 is actuated to drop the stored items discharged from the first vertical conveyor 11 (1) to the second displacement position (step S5), and the process returns to step S4.

  The control device maintains this state until the determination in step S4 becomes YES, that is, until there is no free space at the second displacement position.

  In the case of YES in step S4, that is, when there is no free space at the second displacement position, the control device determines whether or not the central vertical distance is less than a predetermined distance, that is, an appropriate amount of storage has already been thrown into the reference drop position. It is determined whether or not it has been performed (step S6).

  If NO in step S6, that is, if there is an empty space at the reference drop position, the control device moves the moving mechanism 150 so that the first drop position changing means 100 (1) is located at the retracted position. , The stored items discharged from the first vertical conveyor 11 (1) are dropped to the reference drop position (step S7), and the process returns to step S6.

  The control device maintains this state until the central vertical distance is shorter than a predetermined distance based on the detection signal of the central sensor 90, that is, until an appropriate amount of storage items is put into the reference drop position (step S18). ).

In the case of YES in step S18, that is, when an appropriate amount of storage items is thrown into the reference drop position, the control device determines whether or not the first vertical conveyor 11 (1) is raised to the upper limit position ( Step S19).
In the case of NO in step S12, that is, when there is no storage space at the reference drop position, the control device performs the process of step S19.

  The determination in step S19 can be made based on, for example, a detection signal from a position sensor separately provided in the stored item throwing device 1 or control data from the control start time.

  If NO in step S19, that is, if the first vertical conveyor 11 (1) has not been raised to the upper limit position, the control device raises the first vertical conveyor 11 (1) by a predetermined distance. Thus, the lifting mechanism 30 is operated (step S20), and the process returns to step S12.

  According to the loading control mode according to the third example, even if there is a variation in the amount of loading of the stored items per hour by the first vertical conveyor 11 (1), the entire storage space of the storage box 5 is evenly distributed. The state in which the stored items are stored can be automatically displayed.

  As a closing control mode using the central sensor 90, the first displacement sensor 91, the second displacement sensor 92, and the timer means, it is possible to adopt a closing control mode according to the following fourth example.

(1) is positioned at the first guide position, and the stored items discharged from the first vertical conveyor 11 (1) are dropped to the first displacement position.

  On the other hand, when the first displacement side vertical distance has already reached less than the predetermined distance at this time, the control device skips the first guide position and adopts the second guide position as the next operation position. Then, the first drop position changing means 100 (1) is moved to the second guide position, and the stored items discharged from the first vertical conveyor 11 (1) are dropped to the second displacement position.

  That is, in the input control mode according to the fourth example, the fall position where the empty space is filled is basically performed by sequentially dropping the stored items to the plurality of drop positions every predetermined time until the empty space is filled. If there is a drop, the drop position where the empty space is filled is skipped, and the stored items are sequentially dropped to the remaining drop positions where the empty space remains. The first vertical conveyor 11 (1) is raised when an appropriate amount of the stored item is dropped.
