  The above-mentioned conventional storage device having the above-described configuration can reduce the fall distance of the storage product discharged from the lower end portion of the vertical conveyor and effectively reduce the impact when the storage product lands. It is useful in that it can be done, but has the following disadvantages.

That is, in the conventional storage device, the relative position of the vertical conveyor with respect to the storage box in a plan view (the relative position of the vertical conveyor with respect to the storage box in the horizontal direction) is fixed. The discharged articles are piled up in a mountain shape having a vertex near the lower end of the vertical conveyor, and it is likely that the entire storage space of the storage box cannot be effectively used.
In particular, the problem increases as the size of the storage box increases.

  In this regard, for example, Patent Literature 1 below includes a conveyor that conveys a stored product obliquely upward and discharges the stored product diagonally upward along the conveyance direction at a conveyance end portion. A storage container input device configured to store the stored items in a storage box installed below, wherein the input device is configured to cause a speed variation in a peripheral speed of a rotary transmission element that moves an endless body in the conveyor. A device has been proposed.

  In the storage material input device described in Patent Literature 1, the discharge speed of the storage material discharged from the conveyance end portion of the conveyor is changed according to a change in the peripheral speed of the rotary transmission element. It is said that the fall position in the box is changed to prevent the stored items from locally accumulating in the storage box.

However, it is practically very difficult to cause the endless body moving speed to change so that the fall position of the stored item varies depending on the circumferential speed of the rotary transmission element.
Further, in the configuration described in Patent Document 1, the moving speed of the articles discharged from the conveyor has a horizontal component, that is, the conveyor moves the articles horizontally (including diagonally upward or diagonally downward). , And cannot be applied to the storage material input device having the vertical conveyor.

And a second guide region 122 extending to the right.

  The first guide area 121 falls when the first drop position changing means 100 (1) is located at the first guide position on one side around the pivot shaft 105 shown in FIG. 7 from the reference position. It is located on the path, and guides the stored items discharged from the front first vertical conveyor 11 (1) such that the dropped position of the stored items is displaced to one side in the drop position shift direction S from the reference drop position.

  When the first drop position changing means 100 (1) is located at the second guide position on the other side around the pivot shaft 105 shown in FIG. It is located on the path and guides the stored items discharged from the first vertical conveyor 11 (1) such that the falling position of the stored items is displaced from the reference drop position to the other side in the drop position shift direction S.

  According to such a configuration, by dropping the first drop position changing means 100 (1) at the first guide position, the second guide position, and the retreat position, the drop position of the stored item is changed to three positions. can do.

  Further, in the present embodiment, the guide plate 120 is provided on the first vertical conveyor 11 in a state where the first drop position changing means 100 (1) is located at a predetermined reference position around the pivot 105. As viewed in the conveyance width direction (1), as shown in FIG. 4, the shape is a mountain shape having the central region 120C as an apex.

  According to such a configuration, by storing the first drop position changing means 100 (1) at the reference position in addition to the first guide position, the second guide position, and the retreat position, The drop position can be increased.

  Of course, by changing the swing angle of the first drop position changing means 100 (1) about the pivot 105, the drop position of the stored item can be further changed.

  Preferably, a cushion member, such as rubber or felt, may be provided on the upper surface of the guide plate 120, so that the articles discharged from the first vertical conveyor 11 (1) collide with the guide plate 120. The shock at the time can be reduced.

The stored product input device 1 according to the present embodiment includes a moving mechanism 150 that can move the drop position changing unit 100 to a guide position (the first and second guide positions in the present embodiment) and a retreat position. ing.
As described above, in the present embodiment, the drop position changing means 100 is configured to be able to take the guide position and the retreat position around the corresponding pivot 105, and therefore, the moving mechanism 150 The drop position changing means 100 is swung around the pivot 105.
In addition, the storage material input device 1 according to the present embodiment includes the first and second drop position changing units 100 (1) and 100 (2), and the moving mechanism 150 includes the first and second drop position changing units. It is provided corresponding to each of the second drop position changing means 100 (1) and 100 (2).

The moving mechanism 150 can have various forms as long as the position of the drop position changing means 100 can be changed.
In the present embodiment, the moving mechanism 150 has a pair of air cylinders 155 for swinging the pair of swing arms 110 around the pivot shaft.

In the present embodiment, the drop position changing means 100 has a fixed arm 140 that swings integrally around the pivot shaft 105 together with the swing arm 110.
An engaging hole 141 is formed in the fixed arm 140, and by connecting the engaging hole 141 to the air cylinder 151, the drop position changing means 100 can be held at the storage position shown in FIG. It has become.

The storage object input device 1 according to the present embodiment includes a control device (not shown) that controls the operation of the elevating mechanism 30 and the moving mechanism 150.
The control device also controls the transfer operation of the discharge transfer mechanism 10, the main transfer mechanism 40, and the relay transfer mechanism 45.

Hereinafter, a first example of the closing control mode executed by the control device will be described.
FIG. 10 shows a control flow of the closing control mode according to the first example.
The loading control mode according to the first example is based on detection signals from the central sensor 90, the first displacement sensor 91, and the second displacement sensor 92 provided in the storage device 1, and the moving mechanism 150 The operation of the mechanism 30 is controlled.

In the present embodiment, the center sensor 90, the first displacement sensor 91, and the second displacement sensor 92 are connected to the upper end of the stack of stored items at the corresponding drop position and the first vertical conveyor 11 (1). ) Is configured so as to detect the vertical distance from the transport end (lower end).
That is, as shown in FIG. 4 to FIG. 9, in the stored product input device 1 according to the present embodiment, the central sensor 90 includes the upper end portion of the stored product stack at the reference drop position and the The first displacement sensor 91 detects a vertical distance from the center of the vertical conveyor 11 (1), which is a vertical distance from the transport end portion (lower end) of the vertical conveyor 11 (1), with respect to the drop position shift direction S from the reference drop position. A first displacement side vertical distance, which is a vertical distance between the upper end of the pile of stored items at the first displacement position on the side and the transport end of the first vertical conveyor 11 (1), is detected. The two-displacement sensor 92 is provided between the upper end portion of the stack of stored items at the second displacement position on the other side with respect to the drop position shift direction S from the reference drop position and the transport end portion of the first vertical conveyor 11 (1). Detecting the vertical distance of the second displacement side, which is the vertical distance of It has been.
The center sensor 90, the first displacement sensor 91, and the second displacement sensor 92 may be, for example, photoelectric switches.

  The control device activates the closing control mode according to the first example in response to input of a closing work start signal via a start switch or the like.

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

  If NO in step S2, that is, if there is an empty space at the first displacement position, the control device controls the first drop position changing means 100 (1) so that the first drop position changing means 100 (1) is located at the first guide position. The moving mechanism 150 is operated to drop the articles discharged from the first vertical conveyor 11 (1) to the first displacement position (Step S3), and return 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 the second displacement-side vertical distance is less than a predetermined distance, that is, the stored object is at the second displacement position. It is determined whether or not an appropriate amount has already been input (step S4).

  If NO in step S4, that is, if there is an empty space at the second displacement position, the control device controls the first drop position changing means 100 (1) so that the first drop position changing means 100 (1) is located at the second guide position. The moving mechanism 150 is operated to drop the articles 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 vertical distance on the center side is less than a predetermined distance, that is, an appropriate amount of stored items 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 controls the moving mechanism 150 so that the first drop position changing means 100 (1) is located at the retreat position. Is operated to drop the items discharged from the first vertical conveyor 11 (1) to the reference drop position (step S7), and the process returns to step S6.

  The control device maintains this state until the determination in step S6 becomes YES, that is, until there is no free space at the reference drop position.

  In the case of YES in step S6, that is, when there is no free space at the reference drop position, the control device determines whether the first vertical conveyor 11 (1) has been raised to the upper limit position (step S8). .

  The determination in step S8 can be made based on, for example, a detection signal of a position sensor separately provided in the storage object insertion device 1, or control data from the start of control.

  If NO in step S8, 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. The elevation mechanism 30 is operated as described above (step S9), and the process returns to step S2.

  If YES in step S8, that is, if the first vertical conveyor 11 (1) has been raised to the upper limit position, it is determined that the storage box 5 has been filled with stored items, and the loading control mode ends. I do.

  According to the input control mode according to the first example, it is possible to automatically appear a state in which the stored items are uniformly stored in the entire storage space of the storage box 5.

  The predetermined distance in step S2, step S4, step S6, and step S9 can be stored in the control device in advance, or an input means (for example, It is also possible to input via a touch panel).

Hereinafter, a second example of the closing control mode executed by the control device will be described.
FIG. 11 shows a control flow of the closing control mode according to the second example.

  The closing control mode according to the second example uses timer means (not shown) instead of the first and second displacement sensors 91 and 92, and uses the moving mechanism based on the central sensor 90 and the timer means. It controls the operation of the lifting mechanism 150 and the lifting mechanism 30.

  Therefore, in the storage object loading device that executes the loading control mode according to the second example, the first and second displacement sensors 91 and 92 are deleted, and a timer unit that measures the passage of time is provided.

  The control device activates the closing control mode according to the second example in response to the input of a start signal via a start switch or the like.

The control device firstly positions the first drop position changing means 100 (1) at a reference position (see FIG. 4) around the pivot 105 (step S11), and determines whether the center-side vertical distance is equal to or more than a predetermined distance. No, that is, it is determined whether or not there is an empty space at the reference drop position where a stored item can be inserted (step S12).
In step S12, it is determined whether or not there is an empty space in the storage box 5 based on the accumulation state of stored items at the reference drop position.

  If YES in step S12, that is, if it is determined that there is an empty space in the storage box 5, the control device sets the first drop position changing means 100 (1) to the first guide position. Then, the moving mechanism 150 is operated to drop the items discharged from the first vertical conveyor 11 (1) to the first displacement position (Step S13).

  The control device maintains this state for a predetermined time based on the time signal from the timer means (step S14).

  In the case of YES in step S14, that is, when the predetermined time has elapsed, the control device operates the moving mechanism 150 so that the first drop position changing means 100 (1) is located at the second guide position, and The items discharged from the first vertical conveyor 11 (1) are dropped to the second displacement position (Step S15).

  The control device maintains this state for a predetermined time based on the time signal from the timer means (step S16).

  In the case of YES in step S16, that is, when the predetermined time has elapsed, the control device operates the moving mechanism 150 so that the first drop position changing means 100 (1) is located at the retreat position, and The items discharged from the vertical conveyor 11 (1) are dropped to the reference drop position (step S17).

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

In the case of YES in step S18, that is, when an appropriate amount of the stored material is put into the reference drop position, the control device determines whether the first vertical conveyor 11 (1) has been raised to the upper limit position ( Step S19).
In the case of NO in step S12, that is, even 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 of a position sensor separately provided in the storage object insertion 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. The elevating mechanism 30 is operated as described above (step S20), and the process returns to step S12.

  If YES in step S19, that is, if the first vertical conveyor 11 (1) has been raised to the upper limit position, it is determined that the storage box 5 has been filled with stored items, and the loading control mode ends. I do.

Also in the loading control mode according to the second example, it is possible to automatically show a state in which the storage items are stored evenly in the entire storage space of the storage box 5.
In particular, the input control mode according to the second example is effective when the input amount per hour of the storage items by the first vertical conveyor 11 (1) is substantially constant.

  The predetermined distance in steps S12, S18 and S20, and the predetermined time in steps S14 and S16 can be stored in advance in the control device. It is also possible to input via an input means (for example, a touch panel) provided separately in the system.

  It is also possible to add a step using detection signals of the first displacement sensor 91 and the second displacement sensor 92 to the closing control mode according to the second example.

FIG. 12 shows a control flow of the closing control mode according to the third example, in which steps using detection signals of the first displacement sensor 91 and the second displacement sensor 92 are added to the closing control mode according to the second example. .
12, the same steps as those in FIGS. 10 and 11 are denoted by the same step numbers.

  As shown in FIG. 12, in the input control mode according to the third example, after steps S14 and S16 in the input control mode according to the second example, steps in the input control mode according to the first example are respectively performed. S2 and S4 are interposed.

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

  As a closing control mode using the central sensor 90, the first displacement sensor 91, the second displacement sensor 92, and the timer means, a closing control mode according to a fourth example described below may be employed.

  In the input control mode according to the fourth example, the control device positions the first drop position changing means 100 (1) at the first guide position around the pivot shaft 105, and the first vertical conveyor 11 The items discharged from (1) are dropped to the first displacement position.

  The control device stores whether the first displacement-side vertical distance has reached less than a predetermined distance when the first displacement-side vertical distance has reached less than a predetermined distance, or stores the first displacement-side vertical distance after the predetermined time has elapsed. (1) The drop position changing means 100 (1) is positioned around the pivot shaft 105 from the first guide position to the second guide position, and the articles discharged from the first vertical conveyor 11 (1) are displaced by the second displacement. Drop to position.

  The control device stores whether the second displacement-side vertical distance has reached less than a predetermined distance when the second displacement-side vertical distance has reached less than a predetermined distance, or after the predetermined time has elapsed, and (1) The drop position changing means 100 (1) is positioned around the pivot shaft 105 from the second guide position to the retreat position, and the articles discharged from the first vertical conveyor 11 (1) fall to the reference drop position. Let it.

  The control device stores whether or not the center-side vertical distance has reached a distance less than a predetermined distance when the center-side vertical distance has reached a predetermined distance or less, and then stores the information as to whether the center-side vertical distance has reached a value less than a predetermined distance. The means 100 (1) is moved from the retracted position to the next operating position around the pivot 105.

  At this time, if the first displacement side vertical distance has not reached less than the predetermined distance at this time, the control device adopts the first guide position as the next operating position, and the first drop position changing means 100 (1) is located at the first guide position, and the articles discharged from the first vertical conveyor 11 (1) are dropped to the first displacement position.

  On the other hand, if 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 operating position. Then, the first drop position changing means 100 (1) is moved to the second guide position, and the articles 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 drop position where the empty space is filled is basically performed while sequentially dropping the stored items to a plurality of drop positions at predetermined time intervals until the empty space is filled. If there is, skip the falling position where the empty space is filled, and sequentially drop the stored items to the remaining falling position where the empty space remains at predetermined time intervals. The first vertical conveyer 11 (1) is configured to be raised when a suitable amount of stored items has been dropped.

  According to such a fourth example, even if the amount of storage per hour by the first vertical conveyor 11 (1) fluctuates, the storage is uniformly stored in the entire storage space of the storage box 5. Can appear automatically.

  In the loading control modes according to the first to fourth examples, the first vertical conveyor 11 (1) is raised by a predetermined distance based on the detection signal from the central sensor 90, and the first vertical conveyor 11 (1) is raised. ) Reaches the upper limit position, so that the loading of the stored items is terminated. Therefore, the first drop position changing means 100 (1) is first positioned at the guide position and then at the retreat position. However, when the first vertical conveyor 11 (1) is fixedly installed in the vertical direction, the order in which the first drop position changing means 100 (1) is located can be arbitrarily changed.

  Further, in the present embodiment, the first and second vertical conveyors 11 (1) and 11 (2) acting as the discharge / conveyance mechanism can be moved up and down. The 1st displacement sensor 91 and the 2nd displacement sensor 92 are respectively the upper end part of the pile of the storage thing in the corresponding fall position, and the conveyance end of the said 1st and 2nd vertical conveyor 11 (1), 11 (2). The center sensor 90, the first displacement sensor 91, and the second displacement sensor 92 are configured to detect the vertical distance between the lower and upper portions (lower end). It can take various forms as long as the height of the deposit can be detected.

In the present embodiment, the discharge / conveyance mechanism 10 includes the first and second vertical conveyors 11 (1) and 11 (2), and the first and second vertical conveyors 11 (1) and 11 (1). (2) has been described as an example in which the stored items are supplied via the relay conveyor 46. However, it is needless to say that the discharge / conveyance mechanism 10 can be changed to have a single vertical conveyor. is there.
In this case, for example, the relay conveyor 46 is omitted, and the stored items are supplied from the main conveyor 41 to the single vertical conveyor.

  In the present embodiment, the first and second drop position changing means 100 (1) and 100 (2) are configured so as to be able to take a guide position and a retreat position around the corresponding pivot 105. However, the first and second drop position changing means 100 (1) and 100 (2) can take various forms of movement as long as the guide position and the retreat position can be taken.
