Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article stocker used for storing a large number of articles in a physical distribution facility and individually conveying the articles by a conveyor or the like.

[0002]

2. Description of the Related Art Conventionally, an article stocker for storing a large number of articles is arranged in a physical distribution facility in which a conveyor such as a belt conveyor is arranged. Various articles are stored in this article stocker and discharged to a conveyor such as a belt conveyor according to an order. However, the article stocker is arranged on the lower outlet side and can be used together with a picking apparatus for picking articles. Many.

In a conventional picking device, a kicker is reciprocally moved as a means for sequentially discharging the articles stacked vertically from the bottom layer (for example, Japanese Patent No. 3).
No. 057368) or a method of rotating an endless belt provided with a protruding piece (for example, Japanese Patent Laid-Open No. 7-
No. 315573, No. 7-315574, and Japanese Patent No. 2987061). An air cylinder is mainly used in the method of moving the kicker back and forth, and a method in which a timing belt is stretched between a pair of rotating sprockets is used in the method of rotating an endless belt provided with protruding pieces. is there. Further, in response to a recent demand for high-speed picking, a rotary plate type picking device has been developed in which a rotary plate that sequentially presses (picks) the lowermost article is provided at the discharge port on the lower side of the article stocker.

FIGS. 14 and 15 show an example of an article stocker 104 for accommodating a group of articles 105 in a stack and a picking device of a system for moving a kicker back and forth. Picking device P
Is a kicker (picking means) 10 on the mounting base 101.
An air cylinder 102 is provided as a driving means for
The kicker 103 is connected to the air cylinder rod. On one side of the mounting base 101, the kicker 103
Is provided, and a conveyance discharge port 106 through which the lowermost layer article 105a passes is provided on the other side. Picking device P
When the kicker 103 moves backward, the article 105 descends, the lowermost layer article 105a is taken out from the article stocker 104 onto the mounting base 101, and then the forwarder of the kicker 103 moves the lowermost layer article 105a to the transport and discharge port 106. It is pushed out and dropped onto the belt conveyor 107 and conveyed. A weight support member 111 is arranged at the outlet 106 of the article stocker 104 to support the load on one side of the article group 105.

[0005]

In the conventional picking device, the weight support member 111 is the same as that of the article 1 regardless of whether the kicker is reciprocated or the endless belt is rotated.
05 was supported so as to lift only one end side. When a large number of article groups 105 are loaded, the cumulative load increases as the lower layer articles on the discharge port 106 side (the lowermost layer article 105a is the largest). The weight support member 111 is arranged in order to separate it from the lowermost layer article 105a and the second and subsequent articles. However, such one-sided support has a problem that the article group 105a is clogged in the article stocker 104 or the position of the article 105 is displaced unless it is precisely interlocked with the picking means.

On the other hand, in the case of a rotary plate type picking device capable of high-speed picking, the weight of the article becomes heavy,
When a large amount of articles are loaded, a large torque is required to push out and rotate the articles during picking. With a motor with a small rated output, the current value exceeds the rated current value, and there are problems that picking is not possible, the motor heats up due to overcurrent, and the motor life is shortened.A motor with a large rated output is required. Was there. Further, in a servo motor that performs precise position control at high speed, the stop position accuracy is maintained by using a servo lock function that electrically fixes and locks the motor shaft at the motor stop position. If the weight of the article becomes heavy or if a large amount of it is loaded, a current exceeding the rated current value will flow to the servo motor not only during the push-out rotation of the article but also during the servo lock state to hold this stop position. , It will be stopped by the rotation stop command signal from the servo amplifier. afterwards,
When restarting, complicated home return work must be performed, and as a countermeasure, a servo motor with a large rated output and a servo amplifier that controls the servo motor are adopted, which is a major factor in cost increase. Was becoming. In addition, the servo lock does not work when the power is cut off or the power is cut off during non-operating hours, and erroneous picking occurs when the servo motor rotates due to the weight of the article.As a method to prevent this, non-excitation braking means and self-locking ( A worm gear speed reducer with an automatic tightening function is required.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to support the total weight of articles stacked and stored as they are, without hindering the picking operation, and capable of handling high-speed picking. To provide. In addition, when a rotating plate type picking device is used, load torque due to the weight of the article is not applied to the rotating shaft that drives the rotating plate, and the motor is driven by the weight of the article when the power is cut off or the power is cut off during non-operating hours. An object is to provide an article stocker that prevents wrong rotation and picking.

[0008]

It is characterized in that it abuts on the other end side of the support member.

According to the present invention, one control member may be attached so as to surround the rotary shaft of the rotary plate.
Further, since the outer periphery of the control member continuously contacts the other end side of the weight support member, the weight support member can be smoothly rotated by only one control member.

The article stocker according to claim 5 of the present invention is
The other end of the weight support member is provided so as to support the weight of a group of articles to be stored, and the control member, when positioned on the perpendicular line of the center of the rotation axis of the rotary plate, is different from the weight support member. It is characterized in that the end side is supported while being kept in a horizontal posture with respect to the posture of the articles of the article group.

According to the present invention, the control member keeps the other end side of the weight support member in a horizontal posture with respect to the article posture of the article group when the control member is located on the perpendicular of the center of the rotation axis of the rotary plate. Therefore, the rotating shaft of the rotating plate is rotated when the rotating plate is in the stopped state or in the standby state (including the state where the rotating plate is stopped and the power is cut off during non-operating hours or a power failure occurs). The load torque due to the total load of the article group is not generated on the rotary shaft of the rotary plate.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings.

(First Embodiment) In this embodiment, as shown in FIGS. 1 and 2, at a discharge port 6 below an article stocker S for accommodating a large number of articles 5 in a stack, a control member J is provided.
And a weight supporting member G controlled by the rotary plate K rotatably around a rotation axis Ka.
And a motor that is a driving unit 4 that rotationally drives the rotation axis Ka. A plurality of article stockers S are arranged in parallel along a conveyor 7 that conveys the articles 5 in a predetermined direction.
Such an article stocker S may be vertically arranged, and recently, it may be used while being slightly inclined. In the present embodiment, a servo motor having good controllability and large torque is used as the motor, but the present invention is not limited to this.

The article stocker S includes left and right side plates Sa and Sb.

0 has an arc-shaped cross section, is arranged along the rotation direction of the rotary plate K, and plays a role of preventing contact with the article 5 discharged from another article stocker S.

The rotating plate K, as shown in FIGS.
It is made of synthetic resin and is detachably provided at two positions in the axial direction of the drive shaft of the motor which is the drive means 4, that is, the rotation shaft Ka. The base end side and the tip end side of the rotation shaft Ka are attached to the left and right fixed plates 8, 8 provided below the left and right side plates Sa, Sb of the article stocker S. The rotating shaft Ka is connected to the driven shaft from the motor shaft via a coupling C.

Each rotary plate K has a first pressing vane 1, a second pressing vane 2 and a third pressing vane 3 at equal intervals of 120 degrees.
The pressing wings 1, 2, 3 are provided with outer peripheral support surfaces 1a, 2a, 3a each having an outer peripheral surface formed in an arc shape.
And pressing surfaces 1b, 2b, 3b and mounting surfaces 1c, 2c, 3
c is formed (FIG. 4). Therefore, when the rotary plate K rotates counterclockwise about the rotation axis Ka, the pressing surface 1b of the first pressing blade 1 presses the side surface 5d of the lowermost layer article 5A, and then the first pressing blade 1 moves. The outer peripheral support surface 1a supports the bottom surface 5c of the second article 5B from the lowermost article 5A, and then the mounting surface 2c of the second pressing blade 2 receives (places) the bottom surface 5c of the article 5B. Repeat the operation. In the present embodiment, three pressing wings 1, 2, 3 are provided, but it is also possible to provide one, two, or four or more. The pressing surfaces 1b, 2b, 3b and the mounting surfaces 1c, 2
c and 3c are L-shaped predetermined opening angles θ (about 100
Formed in the direction of the central axis of these (mounting surfaces 1c, 2
notches 1e, 2 at the end portions in the central axis direction of c, 3c)
e, 3e are formed. These cutouts 1e, 2
e and 3e are formed so as not to damage the corners of the article 5 when the article 5 is received.

The rotary plate K is rotated by the drive means 4 to rotate the rotary shaft Ka.
When driven to rotate, the first, second and third pressing wings 1,
2 and 3 are connected to each other to press (pick) one side surface 5d of the article 5 while rotating. Such a rotary plate K is designed according to the type and size of the article 5 and is attached to the rotary shaft Ka.

A weight support member G is arranged so as to be located between the two rotary plates K. The weight support member G has an L-shaped cross section, its base end side (upper side) is connected by a shaft Z, and the bottom surface support part Ga on the front end side (the other end side) rotates by a predetermined angle via the shaft Za. (Figs. 2 and 3). The axis Z is the rear plate Sc of the article stocker S.
Is rotatably attached by a fixing plate 9 fixed to
The bottom surface support portion Ga on the tip side (the other end side) is swung by a predetermined angle. The bottom surface support portion Ga is the bottom layer article 5
The bottom surface 5c of A is temporarily supported and then quickly rotated to be inclined and discharged. The tip side Gb is formed in an arc shape in cross section so as to facilitate discharge of the lowermost layer article 5A to the conveyor 7. Has been done. Bottom support G on the other end
a is longer than the center of gravity position Q of the article group 5, and supports the total load of the article group 5 from the lower surface of the article group 5.

The control member J (J1, J2, J3) is shown in FIG.
Further, as shown in FIG. 6, the rotation of the bottom surface support portion Ga on the other end side of the weight support member G is arranged on the outer periphery of the rotation axis Ka of the rotary plate K. That is, although the rotation axis Ka is located at the center of the rotation plate K, the three axes J1, J2, J3 that are the control members are
Mounted on the outer peripheral side of the rotating shaft Ka at equal intervals of 120 degrees, the mounting surfaces 1c, 2c of the pressing wings 1, 2, 3 are attached.
3c is provided at a position to maintain the bottom surface support portion Ga of the weight support member G in a horizontal position when the weight support member 3c is in the horizontal position. That is, the two mounting plates 1c, 2c, 3c are located below the horizontal posture and are provided so as to penetrate the two rotary plates K. Therefore, the mounting surfaces 1c, 2 of the rotary plate K are
At the moment when c and 3c are in the horizontal position, the article group 5 is all supported horizontally from the bottom surface 5c of the lowermost article 5A. When picking, the horizontal posture is immediately released by the rotation of the rotation axis Ka. The radius of the rotary plate K1 of the present embodiment is about 62 mm, and the placing surface 1c is formed to be slightly longer than this length.
By providing the three control members J, that is, the shafts J1, J2, and J3 at 120-degree intervals on the outer circumference of the rotation shaft Ka,
The load of the article group 5 is controlled by the axes J1 to J2 which are the control members J
(Transfer from the axis J2 to the axis J3, and from the axis J2 to the axis J3) (FIGS. 8 to 11). In addition, each pressing wing 1, 2,
3 and each control member J1, J2, J3 must correspond.

Next, the operation of this embodiment will be described. In addition, the article stockers S arranged in parallel on the transport conveyor 7
Stores articles 5 of different types, and the computer program controlling all the article stockers S temporarily rotates only the articles 5 necessary for conveyance on the rotary plate K of the article stocker S. Then, it is discharged (picked) onto the transport conveyor 7.

First, when the article group 5 is stored in the article stocker S, any one of the axes J1, J2 and J3 of the rotary plate K is positioned at a position where the mounting surface 1c of the rotary plate K is maintained in a horizontal posture. (Figs. 8 and 4). At this time, the axis J1 that is the control member is located on the perpendicular O of the center of the rotation axis Ka (in FIG. 4, the axis J1 is located on the perpendicular O of the center of the rotation axis Ka), and the entire article group 5 is Since the weight is supported by the shaft J1, the torque (rotational moment) for rotating the rotation shaft Ka is not generated by the total weight of the article group 5, and as a result, the load torque is not applied to the motor 4. That is,
If the mounting surface 1c of the rotary plate K is kept in the horizontal posture by the motor 4, the shaft J supports the entire weight of the article group 5, so that no load torque is generated (forced rotation). The torque (rotational moment) to turn the plate K is zero). Explaining this in detail, when there is no weight supporting member G controlled by the shaft J1 (or J2, J3) which is a control member (conventional example), the torque (rotational moment) T for forcibly rotating the rotary plate K is , T = Fr. Here, F is the force for rotation (the force due to the total load of the article group 5), and r is the distance from the normal line from the center of gravity Q of the total load of the article group 5 and the center of the rotation axis Ka. , Axis J
When 1 is located on the perpendicular O at the center of the rotation axis Ka, r
Since = 0, the torque (rotational moment) becomes zero, and only bending stress due to the load is generated on the rotation axis Ka. The axis J1 (or J2, J3), which is a control member, is supported by the bottom holding part Ga on the other end side of the weight support member G at the center of gravity position Q of the article group 5, so that the motor 4 is stopped when the motor 4 is stopped. 4 of the brake function (in the case of an induction with a brake, the non-excitation brake, the servomotor function of the servomotor), the total load of the article group 5 that tries to rotate the motor shaft (the rotation shaft Ka of the rotating plate K). The load torque is not generated on the rotary shaft Ka of the rotary plate K. The rotating plate K of the article stocker S is temporarily rotated by the computer program controlling all the article stockers S, and the rest is in the standby state. (Including when the power is cut off or when there is a power failure) during that time) supports the entire load of the article group 5 via the weight supporting member G.

Next, when the rotary plate K is rotated via the rotary shaft Ka by driving the driving means (servo motor) 4, the pressing blades 1, 2 and 3 perform a pinking operation of sequentially pressing from the lowermost layer article 5A. Although it starts, at the same time, the shafts J1, J2, J3, which are the control members J for controlling the weight supporting member G, rotate. When the rotary shaft Ka rotates counterclockwise, the shaft (control member) J1 located on the mounting surface 1c side of the first pressing blade 1 is located.
Simultaneously tilts the weight support member G counterclockwise,
The pressing surface 1b of the first pressing blade 1 presses the one side surface side 5d of the lowermost layer article 5A, and the outer peripheral support surface 1a supports the lower surface of the second article 5B from the lowermost layer article 5A (Fig. 9), the lowermost layer article 5 is discharged (FIG. 10). Next, the shaft J2 located on the mounting surface 2c side of the second pressing blade 2
After pushing up the bottom surface support portion Ja of the weight support member G inclined to a horizontal posture, the weight support member Ja is further rotated and then inclined at a predetermined angle. Subsequently, the weight support member G having the inclined axis J3 located on the mounting surface 3c side of the third pressing blade 3 is pushed up to a horizontal posture, and is further rotated to be inclined (lowered) by a predetermined angle. That is, when the rotary plate K rotates, the axes J1, J2, J3 of the control member J alternately abut on the bottom surface support portion Ga of the weight support member G1 (to make a rattling sound and generate a light sound), and after being in a horizontal position. The operation of tilting is repeated (FIG. 11 is the same as FIG. 8 except for the position of the pressing blade of the rotary plate K). As described above, since the control member J is arranged on the rotary plate K, the high-speed picking due to the rotation is accurately followed, while the first, second and third pressing wings 1, 2, 3 are ,
It is only necessary to exert the force of pressing. That is,
The pressing blades 1, 2, 3 are pressed (picked) in order from the lowermost article 5A with a light force using the centrifugal force generated by the rotation of the rotary plate K (the torque of the motor 4 acts as the rotary picking force as it is). Becomes Further, since the weight support member G is controlled by the rotation of the rotary plate K via the control member J, the start position of the rotary plate K is not displaced by the load of the article 5, and the control member J is driven. It is not necessary to separately provide a driving means for driving.

In this embodiment, since the article stocker S is in the vertical posture, the bottom surface support portion Ja of the weight support member G repeats the horizontal posture, but the article stocker S is inclined. When the weight support member G is used in a tilted state, the article stocker S may be tilted as it is while maintaining the horizontal posture of the weight support member G. In addition, the three axes J that are control members
When changing the mounting positions of 1, J2 and J3, as shown in FIG. 7, the elongated hole 11 is formed in the central axis of the rotating plate K so that the mounting positions of the shafts J1, J2 and J3 are changed. It is possible to That is, the article stocker S
Depending on the angle of inclination of the control member J, the control member J may not be accurate or may be deformed due to long-term use. In such a case, the position of the control member J (J1, J2, J3) is set by the elongated hole 11. It is possible to correspond by adjusting and using.

(Second Embodiment) In the present embodiment, as shown in FIG. 12, one control member J is integrally attached to a rotary shaft Ka of the rotary plate K. That is, the rotation control portions Ja, Jb, Jc corresponding to the plurality of pressing wings 1, 2, 3 are formed in one control member J in a substantially triangular shape. In the present embodiment, the rotating plate K is 3
This is an example of the case where the pressing blades 1, 2, and 3 are provided, and for example, the rotation control units Ja and Jb when the rotary plate K has the two pressing blades 1 and 2 correspond to the numbers. There will be two. In this way, the rotation control parts Ja, Jb of the control member J,
Although Jc is provided in a number corresponding to the plurality of pressing wings 1, 2, and 3, in terms of manufacturing, it suffices to manufacture one control member J having the substantially triangular shape.

The two control members J of this embodiment are provided below the weight support member G.
It is also possible to provide one just under a. Further, the control member J may be detachably attached to the rotary plate K (or the rotary shaft Ka) so that the control member J can be changed and used.

Therefore, when the rotary plate K is rotated by the drive of the drive means 4 via the rotary shaft Ka, the control member J for controlling the weight supporting member G rotates, but the control member J of the present embodiment is Since it has a substantially triangular shape and is integrally attached to the outside of the rotation axis Ka, as in the first embodiment, the shafts J1 to J2 (the shafts J2 to J3, which are the control members J) are attached. The bottom of the weight support member G1 is arranged along the outer periphery of one control member J, instead of transferring the entire load of the article group 5 that is stacked and stored so as to be transferred from the shaft J3 to the shaft J1). The support portion Ja comes into contact with each other to ensure smooth rotation at a predetermined angle without generating sound. That is, even when the number of rotation control parts Ja, Jb, Jc corresponding to the first embodiment is small (even when the number of pressing wings is small), the bottom support part Ga of the weight support member G can be smoothly moved by a predetermined angle. While rotating, the rotational torque (load torque) due to the total load of the article group 5 applied to the rotation axis Ka at the stop position is zero, and only the bending stress due to the load is generated on the rotation axis Ka. . If the control member J has a gentle arcuate outer peripheral surface as shown in FIG. 13, the weight support member G can be rotated more smoothly.

As described above, the article stocker S of this embodiment is
The method of rotating the rotary plate K1 as a picking means at a high speed by a motor such as a servo motor has been described, but the present invention is a method of reciprocating (oscillating) within a predetermined angle range by using an air cylinder or an air cylinder as a driving means. It is also applicable to.

[0034]

The article stocker of the present invention comprises a weight support member for supporting an article, which is stacked and accommodated in the lower discharge port, in which one end is pivotally supported and the other end is rotatable, from the lower side thereof, Since the control member for controlling the rotation of the other end side of the weight support member is provided, if this control member is rotationally controlled,
The rotation angle of the weight support member in which one end side is pivotally supported and the other end side is rotated is controlled to a predetermined angle, and the weight support member rotates the predetermined angle after supporting the total weight of the articles stored in the stack. The articles to be stacked and stored will be discharged accurately in the predetermined direction in order from the lowest layer article.

When the control member is attached to a rotating plate which is pressed in order from the lowest layer article while rotating, and is applied, when the rotating plate is rotated by the rotation of the rotating shaft by the driving means, the control member is rotated. The control member can control the rotation of the other end side of the weight supporting member in accordance with the movement of the rotating plate that is pressed (picked) while rotating, and it is necessary to separately provide a driving means for driving the control member. Disappears. Further, it is possible to reduce the load torque applied to the rotary shaft of the rotary plate during the extrusion rotation of the article, and to eliminate the load torque due to the total load of the article group at the stop position of the rotary plate during the stop of the driving means. Even when performing high-speed and precise position control like
The control can be performed without trouble by an inexpensive small motor or servo amplifier, and it is not necessary to provide the motor with a self-lock function or the like. Further, it becomes possible to prevent erroneous picking in which the driving means (motor) rotates due to the weight of the article when the power is cut off or the power is cut off outside the operating hours.
