Description

  The present invention relates to a stopper device and an automatic warehouse.

  In a warehouse such as an automatic warehouse that accommodates a large number of conveyed items, it is preferable that the movement of the conveyed items is regulated by a stopper so that the position of the conveyed items that are accommodated by an external force such as an earthquake does not shift. In particular, a stopper is indispensable when a transported object having a shape that is easy to roll, such as a barrel shape, is accommodated.

  For example, Patent Document 1 discloses a configuration in which a stopper device is fixedly disposed at a storage position of a stored item, and the movement of the stored item is regulated by the stopper device. Further, Patent Document 2 discloses a stopper that can be attached to and detached from an accommodation portion by an operator.

JP 2000-344308 A JP 2001-139145 A

  By the way, some warehouses accommodate a plurality of transported objects arranged in a straight line with respect to one storage unit. In such a type of warehouse, it is not necessary to regulate the movement because other than the transported object placed at the end is sandwiched between other transported objects. Therefore, it is only necessary to restrict the movement of the transported object arranged at the end.

  However, since the ends of the transported objects arranged in a straight line vary depending on the number of transported objects, the position of the end is fluid. Therefore, if it is going to apply the stopper device described in patent documents 1, it is necessary to install many stopper devices to one storage part. Therefore, the work load for installing the stopper device becomes enormous and the maintenance work efficiency deteriorates.

  According to the stopper disclosed in Patent Document 2, it can be installed only on a transported object arranged at the end, and the number of stoppers can be reduced. However, an operator needs to attach and detach one by one. The work burden is not light. In particular, when the storage portion is located at a high position, the labor required for the worker to safely reach the storage portion is large, and the work efficiency is extremely deteriorated.

  The present invention has been made in view of the above-described problems, and minimizes the number of stopper devices required in a warehouse in which a plurality of conveyed items are accommodated in a straight line with respect to a single accommodating portion. The stopper device can be easily installed.

  The present invention adopts the following configuration as means for solving the above-described problems.

  1st invention is a stopper apparatus, Comprising: The driving | running | working which is moved between the said rails by being pushed by the conveyance trolley which is guided to a pair of rail in which a conveyed product is mounted, and moves the said conveyed product A stopper having an upper end portion which is supported rotatably about a horizontal axis perpendicular to the moving direction of the traveling vehicle with respect to the traveling vehicle and which protrudes upward; Urging means for urging a reference posture disposed above a lower end position of the conveyed product, and a direction in which the upper end portion tilts the upper end portion toward the conveying cart when not pushed by the conveying cart A configuration is adopted in which a lock mechanism is provided that restricts the rotation only so as not to rotate, and releases the restriction when being pushed by the transport carriage.

  According to a second invention, in the first invention, the lock mechanism includes a projecting plate fixed to the stopper, and an opposing plate that is disposed to face the projecting plate and restricts the movement of the projecting plate. A contact portion disposed at a position that contacts the transport carriage, a slide rail that supports the contact portion movably along the rail, and the contact portion when the contact portion is pushed in by the transport carriage. A contact portion biasing means for removing the counter plate from the position facing the projecting plate and disposing the counter plate at a position facing the projecting plate when the contact portion is not pushed in by the transport carriage; A configuration of providing is adopted.

  In a third aspect based on the second aspect, the contact portion is disposed on the traveling vehicle, and a through hole is provided at a position overlapping the contact portion and the traveling vehicle as viewed from above. The configuration is adopted.

  According to a fourth invention, in any one of the first to third inventions, the traveling vehicle includes a base portion and a wheel provided on the base portion and abutting against a side portion of the rail. A wheel that is in contact with one of the rails is a fixed wheel fixed to the base portion, and a wheel that is in contact with the other rail of the wheels is supported so as to be movable in the horizontal direction with respect to the base portion. The configuration that is said to be adopted.

  5th invention is an automatic warehouse provided with the accommodation shelf which has a pair of rail in which a conveyed product is mounted, and the conveyance trolley which is guided to the said rail and moves the said conveyed product, Comprising: The said 1st-1st 4 The structure which is provided with the stopper apparatus which is either invention is employ | adopted.

  In the present invention, when the lock mechanism of the stopper device is not pushed in by the transport carriage, the stopper is regulated by the lock mechanism so that the upper end portion does not rotate only in the direction of tilting toward the transport carriage. For this reason, when the transport carriage is separated from the stopper device, even if the transport object is about to move from the side opposite to the direction in which the transport carriage accesses, the stopper does not rotate. Is regulated. The restriction of the stopper by the lock mechanism is only in the above direction when the lock mechanism of the stopper device is not pushed in by the transport carriage. For this reason, when the stopper device is moved while pushing the lock mechanism by the transport carriage or when the stopper device is moved while pulling the stopper device by the transport carriage, even if there is a transported object in the moving direction of the stopper device. Since the stopper abuts on the conveyed product and rotates, the stopper device can be moved beyond the conveyed item. Therefore, according to this invention, a stopper apparatus can be installed in arbitrary places irrespective of an operator. Therefore, according to the present invention, it is possible to minimize the number of stopper devices required and easily install the stopper devices in a warehouse in which a plurality of conveyed items are accommodated in a straight line with respect to one accommodating portion.

Two through holes 10a2 are provided on the front side of the base plate 10a. These through holes 10a2 are provided at positions overlapping the stopper 11 when viewed from above.

  A plurality of wheels 10b are attached to the base plate 10a so as to be rotatable about a rotation axis that faces the vertical direction. These wheels 10b are arranged above the base plate 10a. Further, as shown in FIG. 3B, the peripheral surfaces of these wheels 10b are curved so as to come into contact with the rail 2b having a circular cross section, and are brought into contact with the side portion of the rail 2b. Of these wheels 10b, the wheel 10b that is in contact with one rail 2b is a fixed wheel 10b1 fixed to the base plate 10a, and the wheel 10b that is in contact with the other rail 2b is in the base plate 10a. On the other hand, the movable wheel 10b2 is supported so as to be movable in the horizontal direction (left-right direction).

  The stoppers 11 are provided on both sides of the center of the traveling vehicle 10 when viewed from the front-rear direction. These stoppers 11 are supported so as to be rotatable around a horizontal axis perpendicular to the moving direction of the traveling vehicle 10 by being axially supported by a shaft support pin 12 arranged with its axial direction directed in the left-right direction. Yes. As shown in FIG. 3A, such a stopper 11 has a shape in which the upper side protrudes in the radial direction of the pivot pin 12 as compared with other portions as viewed from the left-right direction. This overhanging portion is referred to as an upper end portion 11a. That is, the stopper 11 has a shape having an upper end portion 11a that protrudes upward as viewed from the left-right direction.

  The pivot pin 12 is provided for each stopper 11 and is fixed to the traveling vehicle 10. The stopper spring 13 is provided for each stopper 11, one end being fixed to the traveling vehicle 10 and the other end being fixed to the stopper 11. The other end of the stopper spring 13 is fixed at a position shifted to the front side at the same height with respect to the pivot pin 12 as shown in FIG. Further, as shown in FIG. 2, the stopper spring 13 is a position displaced in the left-right direction with respect to the stopper 11 when viewed from above, and is disposed at a position that does not hinder the rotation of the stopper 11. Such a stopper spring 13 biases the stopper 11 to a reference posture in which the upper end portion 11 a is disposed above the lower end position of the barrel X.

  The lock mechanism 14 includes a protruding plate 14a, a contact plate 14b (contact portion), a slide rail 14c, a contact plate spring 14d (contact portion biasing means), and a contact plate stopper 14e. ing. The protruding plate 14 a is provided for each stopper 11. Each protruding plate 14a is fixed at a position shifted to the rear side at the same height with respect to the pivot pin 12, and is installed so that the front and back surfaces are directed vertically when the stopper 11 is in the reference posture. Yes.

  The contact plate 14b is disposed on the base plate 10a of the traveling vehicle 10, and has a plate-like base portion 14b1 whose width in the left-right direction is set so as not to interfere with the protruding plate 14a, and a front end of the base portion 14b1. And a counter plate 14b2 provided so as to protrude in the left-right direction with respect to the portion. The amount of protrusion of the opposing plate 14b2 from the base portion 14b1 is set so that the opposing plate 14b2 can enter the lower side of the protruding plate 14a and face the protruding plate 14a. Further, as shown in FIG. 2, a through hole 14b3 is provided on the rear side of the base portion 14b1. The through hole 14b3 is provided at a position overlapping the through hole 10a1 provided in the base plate 10a of the traveling vehicle 10 when viewed from above.

  The slide rails 14c are provided on the base plate 10a of the traveling vehicle 10, and are provided on both sides of the center of the base plate 10a when viewed from the front-rear direction. These slide rails 14c support the contact plate 14b from below, and can move the contact plate 14b in the front-rear direction.

  One end of the contact plate spring 14d is fixed to the upper surface of the base plate 10a of the traveling vehicle 10, and the other end is fixed to the upper surface of the base portion 14b1 of the contact plate 14b. The contact plate spring 14d removes the opposing plate 14b2 from the position facing the protruding plate 14a when the contact plate 14b is pressed by the transport carriage 5, and the contact plate 14b is pressed by the transport carriage 5. The contact plate 14b is urged so that the opposing plate 14b2 is disposed at a position facing the protruding plate 14a when there is not.

  The contact plate stopper 14e is provided on the base plate 10a of the traveling vehicle 10 in the front side of the contact plate 14b and the region exposed by the through hole 14b3 provided in the base portion 14b1 of the contact plate 14b. These contact plate stoppers 14e are set to contact with the contact plate 14b moved in the front-rear direction with respect to the traveling vehicle 10 and define the end of the contact plate 14b moving range on the travel vehicle 10. To do.

  In such a lock mechanism 14, as shown in FIG. 4A, when the contact plate 14 b is not pushed in by the transport carriage 5, the opposing plate 14 b 2 is disposed opposite to the protruding plate 14 a. For this reason, when the stopper 11 tries to rotate so that the upper end portion 11a tilts toward the transport carriage 5 (rear side), the movement of the stopper 11 is restricted by the interference of the protruding plate 14a with the opposing plate 14b2. However, even when the opposing plate 14b2 is arranged opposite to the lower side of the protruding plate 14a, the stopper 11 can be rotated so that the upper end portion 11a tilts toward the arrangement side (front side) of the barrel X. Further, when the contact plate 14b is pushed by the transport carriage 5, as shown in FIG. 4B, the opposing plate 14b2 is removed from the position facing the protruding plate 14a, and the restriction is released. For this reason, the stopper 11 can be rotated in any direction.

  The operation using the stopper device 8 configured as described above will be described with reference to FIGS. 5 and 6, only the fork 5a is shown for the transport carriage 5, and the stopper device 8 is shown in a simplified manner.

  When the barrel X already placed on the rail 2b is moved, the stopper device 8 arranged in front of the barrel X is pressed by the fork 5a of the transport carriage 5 as shown in FIG. Thus, when the stopper device 8 is moved by the fork 5a of the transport carriage 5, the stopper 11 comes into contact with the barrel X, and the reaction force against the pressing force by the transport carriage 5 exceeds the urging force of the contact plate spring 14d. As a result, the contact plate 14 b is pushed into the traveling vehicle 10. As a result, the lock on the stopper 11 is released, and as shown in FIG. 5B, the stopper 11 rotates so as to tilt the upper end portion 11a toward the transport carriage 5 side. As a result, the upper end portion 11a of the stopper 11 is pushed down, and the stopper device 8 moves forward beyond the barrel X on the near side.

  Thereafter, as shown in FIG. 5C, the barrel X on the near side is moved by the fork 5 a of the transport carriage 5. At this time, the stopper device 8 is already arranged in front of the barrel X arranged next to the movement target. Further, since the transport carriage 5 is separated from the stopper device 8, the stopper 11 cannot be rotated so that the upper end portion 11a is tilted toward the transport carriage 5 side. Therefore, the movement of the barrel X can be restricted by the stopper device 8.

  On the other hand, when the barrel X is added on the rail 2b, the fork 5a of the transport carriage 5 that moves the barrel X to be added is hooked on the stopper device 8 as shown in FIG. More specifically, the fork 5a is inserted into the through hole 14b3 of the contact plate 14b and the through hole 10a1 of the base plate 10a, and the fork 5a is hooked on the stopper device 8 thereby.

  Subsequently, the transport cart 5 is moved backward, and the stopper device 8 is pulled by the transport cart 5. Thereby, the stopper device 8 is moved backward. At this time, the lock of the stopper 11 by the lock mechanism 14 is not released, but even in this case, the stopper 11 tilts toward the barrel X on which the upper end portion 11a is placed first. It can rotate. Therefore, as shown in FIG. 6B, the stopper 11 rotates so that the upper end portion 11a tilts toward the barrel X on which the stopper 11 is placed first when it hits the added barrel X. As a result, the stopper device 8 is placed over the added barrel X and in front of the added barrel X as shown in FIG. When the transport carriage 5 is retracted, the transport carriage 5 is separated from the stopper device 8, so that the stopper 11 cannot be rotated so that the upper end portion 11 a is tilted toward the transport carriage 5. Therefore, the stopper device 8 can regulate the movement of the added barrel X.

  In the stopper device 8 as described above, when the lock mechanism 14 is not pushed in by the transport carriage 5, the lock mechanism 14 prevents the upper end portion 11a from rotating only in the direction of tilting toward the transport carriage 5 side. 11 is regulated. For this reason, even when the barrel X is about to move from the side opposite to the direction in which the transport carriage 5 accesses when the transport carriage 5 is separated from the stopper device 8, the stopper 11 does not rotate. The movement of the barrel X is restricted. The restriction of the stopper 11 by the lock mechanism 14 is only in the above direction when the lock mechanism 14 of the stopper device 8 is not pushed in by the transport carriage 5. For this reason, when the stopper device 8 is moved while pushing the lock mechanism 14 by the transport carriage 5 or when the stopper device 8 is moved while pulling the stopper device 8 by the transport carriage 5, the stopper device 8 is moved forward in the moving direction. Even if the barrel X exists, the stopper 11 comes into contact with the barrel X and rotates, so that the stopper device 8 can be moved beyond the barrel X. Therefore, according to the stopper device 8, the stopper device 8 can be installed at an arbitrary place regardless of the operator. Therefore, according to such a stopper device 8, in the automatic warehouse 1 in which a plurality of barrels X are accommodated linearly with respect to one accommodating portion 2a, the number of necessary stopper devices 8 is minimized and The stopper device 8 can be easily installed.

  In the stopper device 8, the lock mechanism 14 includes a protruding plate 14 a fixed to the stopper 11, and a counter plate 14 b 2 that is disposed to face the protruding plate 14 a and restricts the movement of the protruding plate 14 a, and is attached to the transport carriage 5. A contact plate 14b disposed at a contact position, a slide rail 14c that supports the contact plate 14b so as to be movable along the rail 2b, and a counter plate when the contact plate 14b is pushed in by the transport carriage 5. 14b2 is removed from the position facing the projecting plate 14a, and provided with a contact plate spring 14d for disposing the facing plate 14b2 at the position facing the projecting plate 14a when the contact plate 14b is not pushed by the transport carriage 5. . According to such a stopper device 8, the stopper 11 can be locked and unlocked only by the power of the transport carriage 5 without using an actuator.

  Further, in the stopper device 8, a contact plate 14b is disposed on the traveling vehicle 10, and a through hole 10a1 and a through hole 14b3 are provided at positions overlapping the contact plate 14b and the traveling vehicle 10 when viewed from above. . For this reason, the conveyance cart 5 can be easily hooked to the stopper device 8.

  Further, in the stopper device 8, the wheel 10b that contacts the one rail 2b of the wheels 10b is a fixed wheel 10b1 fixed to the base plate 10a, and the wheel 10b that contacts the other rail 2b of the wheels 10b is the base plate 10a. The movable wheel 10b2 is supported so as to be movable in the horizontal direction. For this reason, even if it is a case where the width | variety of the rail 2b changes, the stopper apparatus 8 can be made to drive | work reliably.

  Moreover, since the automatic warehouse 1 of this embodiment regulates the movement of the barrel X using the stopper device 8 as described above, the number of necessary stopper devices 8 is minimized and the stopper device is used. It is an automatic warehouse where 8 can be installed easily.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the said embodiment. Various shapes, combinations, and the like of the constituent members shown in the above-described embodiments are examples, and various modifications can be made based on design requirements and the like without departing from the spirit of the present invention.

  Moreover, in the said embodiment, the structure whose conveyance thing is the barrel X was demonstrated. However, the stopper device of the present invention is not limited to this, and can be installed even in an automatic warehouse that accommodates any conveyed items. It can also be installed in a warehouse other than an automatic warehouse.

  Moreover, in the said embodiment, the structure using the conveyance trolley 5 which lifts and conveys the barrel X was demonstrated. However, the automatic warehouse of the present invention is not limited to this, and it is possible to adopt a configuration using a transport cart that moves the barrel X while rolling it.
