Description

The present invention relates to a pallet fall prevention device for a mechanical parking device.

For example, in an elevator type parking device, when a vehicle is warehousing, the vehicle is placed on a pallet at the warehousing / delivery section, the pallet is placed on a cage to move up and down in the hoistway, and one of a plurality of shelves arranged along the hoistway. Transfer the pallets to one and store the pallets on the shelves.
On the contrary, when the vehicle leaves the garage, the cage is raised and lowered to stop at the target shelf, the pallet is transferred from the shelf to the cage, the cage is raised and lowered to the warehousing / delivery section, and the vehicle is lifted from the pallet at the warehousing / delivery section. Issue the goods.

In the elevator parking device described above, each pallet can move horizontally between the cage and the shelf. Therefore, a pallet holding device is provided to prevent the pallet from moving into the hoistway except when entering and leaving the warehouse.

The pallet holding device described above is disclosed in, for example, Patent Documents 1 and 2.

The "pallet holding device in a mechanical three-dimensional parking device" of Patent Document 1 has a stopper lever that can swing about a horizontal axis at a cage-side end of a shelf. The stopper lever has a regulating member fixed to the shelf side end portion thereof to prevent the pallet from moving into the hoistway at a descending position, and a release member fixed to the cage side end portion of the stopper lever. The release member engages with a release striker provided on the cage, and the restricting member swings to the release position by its lowering operation to release the engagement with the stopper pin.

The "pallet holding device of a mechanical parking device" of Patent Document 2 includes a stopper member attached to each storage shelf and capable of turning around a horizontal axis below the pallet. The stopper member has long and short striker portions that are orthogonal to each other, and one of them is positioned upward. The long striker section is set long so as not to hinder the movement of the pallet, and the short striker section is set short so as not to hinder the movement of the pallet. By rotating the swivel arm when loading the pallet, the long striker part is swiveled by the swivel arm to open the position, and by rotating the swivel arm when feeding the pallet, the short striker part is swiveled by the swivel arm and closed after paying out. To position.

Japanese Unexamined Patent Publication No. 2013-83073 Japanese Unexamined Patent Publication No. 11-324381

In the pallet holding device of Patent Document 1, a dedicated actuator for driving the release striker provided in the cage between the retracted position and the protruding position is required.

Further, in the pallet holding device of Patent Document 1, the release striker is moved from the retracted position to the protruding position above the shelf traversing the pallet, and the cage is once moved through the release striker at the height of the target shelf. Remount in a fixed position to maintain cage height and level.
This remounting operation is called a "soft landing operation", and the mechanism is called a "soft landing mechanism".

This soft landing operation had the following problems.
Before stopping the cage on the stop floor, extra operations such as "stop at a height slightly above the stop height" and "move the positioning stopper from the retracted position to the support position" are required. On the contrary, before raising or lowering the cage to the next stop floor from the state of being stopped on the stop floor, "rise and stop from the stop height to a height slightly above" and "from the support position of the positioning stopper". Extra operations such as "move to evacuation position" are required.
Therefore, due to the soft landing operation, the time for entering and leaving the vehicle becomes long, and the smoothness is lowered.

Further, in the pallet holding device of Patent Document 1, since the cage is replaced with the fixed position via the release strikers provided at the four corners, when the cage stops on the stop floor, the stopper levers provided on both sides of the cage are released. It becomes.
Therefore, if an earthquake occurs while the pallet is traversing, the pallet stored on the non-traversing side may move to the cage side and interfere with the traversing pallet. In addition, there is a possibility that the parking device itself cannot be continuously operated.

The pallet holding device of Patent Document 2 has an advantage that a dedicated actuator and a soft landing operation are not required.
However, in the pallet holding device of Patent Document 2, it is necessary to attach a stopper member to the central portion of each shelf on the cage side corresponding to the central axis of the swivel arm on the cage. Therefore, the stopper member and the frame supporting the stopper member are located between the upper and lower shelves, which may interfere with the traveling vehicle. Therefore, a dead space corresponding to the height of the stopper member and the frame supporting the stopper member is generated on each shelf, and it is necessary to increase the height of the entire parking device or limit the vehicle to be stored to a vehicle having a low vehicle height. Occurs.

The present invention has been devised to solve the above-mentioned problems. That is, an object of the present invention is to provide a pallet fall prevention device for a mechanical parking device that does not require a dedicated actuator and a soft landing operation, does not malfunction due to an earthquake, and has no dead space between the upper and lower pallets. There is.

According to the present invention, a cage on which a pallet on which a vehicle is placed is placed to move a moving path, a traversing device installed on the cage to horizontally traverse the pallet, and a traversing device arranged along the moving path to store the pallet. Equipped with a storage shelf
The traversing device has a traversing arm that extends horizontally and is swiveled around a swivel vertical axis.
The pallet is a pallet fall prevention device for a mechanical parking device that traverses horizontally with an adjacent storage shelf by turning the traversing arm.
The pallet has a stopper pin extending horizontally in the longitudinal direction at the longitudinal end on the moving path side.
The storage shelf abuts on the stopper pin at the locking position at the longitudinal end on the moving path side to prevent the pallet from moving to the moving path side, and drops to release the contact with the stopper pin at the releasing position. Has a prevention lever
The cage is provided with a pallet fall prevention device for a mechanical parking device, which has a lever release device for moving the fall prevention lever from the locking position to the release position by turning the traversing arm.

According to the present invention, since the cage has a lever release device that moves the fall prevention lever from the locked position to the release position by turning the traverse arm by the traverse device, an actuator dedicated to the pallet fall prevention device is unnecessary.

Further, since the lever release device can be operated by the traversing device without stopping the cage on the stop floor by the soft landing mechanism, the soft landing operation is unnecessary.

Further, since the pallet has a stopper pin at the longitudinal end on the moving path side and the storage shelf has a fall prevention lever at the longitudinal end on the moving path side, the upper and lower storage shelves other than the longitudinal end of the storage shelf. There is no member located in the middle of the movement path side of the shelf, and there is no dead space between the upper and lower pallets of the storage shelf. Therefore, there is no possibility that the traversing vehicle and the fall prevention lever interfere with each other, and a vehicle having a high vehicle height can be stored without increasing the height of the entire parking device.

It is a traction type (friction drive type) hoisting machine installed on the upper part of the.
In this example, the moving path 3 is a hoistway, and the cage 5 is moved up and down.
Further, the elevator type parking device 100 is not limited to the traction type, and may be a drum type.
Furthermore, the present invention is not limited to the elevator type parking device 100, and can be applied to other mechanical parking devices.

FIG. 2 is a perspective view showing the elevating mechanism of FIG.
In FIG. 2, the elevator type parking device 100 includes a plurality of (4 sets in this example) suspension ropes 12, counterweights 14, and cables 16 (elevator cables).

The plurality of suspension ropes 12 suspend the cage 5 on which the vehicle 1 is placed, extend vertically upward, and are moved up and down in synchronization with each other from the upper part of the hoistway 3.
In this example, the four sets of suspension ropes 12 have one ends 12a fixed to the four corners of the cage 5 on which the vehicle 1 is placed, suspend the cage 5 and extend vertically upward, and are inverted by the upper sheave 8 at the upper part of the hoistway 3. Extends downward. The hanging rope 12 is preferably a wire rope.
The number of suspension ropes 12 in each set is one in this figure, but it is preferable that there are two or more. The diameter of the upper sheave 8 (pulley) can be reduced by forming each set of hanging ropes 12 with two or more ropes.

In FIG. 2, the upper sheave 8 is a fixed pulley fixed to the upper part of the hoistway 3, and in this example, four first sheaves 8a, two second sheaves 8b, one third sheave 8c, and one. It consists of a fourth sheave 8d. The upper sheave 8 guides the hanging rope 12 from the cage 5 to the counterweight 14 in order.
In this example, a drive sheave 9 for frictionally driving the suspension rope 12 located between the second sheave 8b and the third sheave 8c is installed. The hoisting machine 7 rotationally drives the drive sheave 9.

In FIG. 2, the counterweight 14 is suspended from the other end 12b of the four sets of hanging ropes 12 and moves up and down. The counterweight 14 is preferably set to a weight that reduces the drive load by adding the weight distribution in the presence or absence of the vehicle 1 (for example, the weight of the pallet 2) to the weight of the cage 5.

The cable 16 is a power line and a signal line, one end 16a is fixed to the cage 5, the other end 16b is fixed to the rear inner wall 3a of the hoistway 3, and the intermediate portion is loosened downward and hung. ..

FIG. 3 is a schematic side view of FIG. 2, and FIG. 4 is a view taken along the line AA of FIG.

In FIG. 4, the elevator parking device 100 includes a cage 5, a traversing device 20, and a storage shelf 4.
The cage 5 carries a pallet 2 on which the vehicle 1 is placed and moves up and down the hoistway 3. The traversing device 20 is installed on the cage and traverses the pallet 2 horizontally. The storage shelf 4 is arranged along the hoistway 3 and stores the pallet 2.

In FIG. 4, the traversing device 20 has a traversing arm 22 that extends horizontally and is swiveled around a swivel vertical shaft 24a. The pallet 2 traverses horizontally with the adjacent storage shelves 4 due to the rotation of the traversing arm 22.

In FIG. 4, the traversing device 20 has a traversing drive device 24 and an engaging dock 26.
The traverse drive device 24 rotationally drives a swivel vertical shaft 24a in which the inner end portion of the traverse arm 22 is fixed and extends in the vertical direction. In this example, the traverse drive device 24 rotationally drives the swivel vertical shaft 24a via the gear reducer 24b.
The engagement dock 26 is provided at the outer end of the transverse arm 22 and extends upward.
In this figure, the swivel vertical shaft 24a is different from the center O in the width direction and the length direction of the cage 5, and is shifted to one of the length directions.
Note that this configuration is not essential, and the swivel vertical shaft 24a may be installed at or near the center O.

The pallet 2 has a dock rail 2a extending in the longitudinal direction at the end in the width direction and having an inverted U-shaped cross section.
With the engaging dock 26 engaged with the dock rail 2a, the pallet 2 traverses horizontally (vertically in the figure) with the adjacent storage shelf 4 due to the rotation of the traversing arm 22.
In this figure, the storage shelf 4 has a horizontal support member 4a extending horizontally at both ends in the longitudinal direction thereof, and a plurality of free rollers 4b fixed to the horizontal support member 4a and freely rotating about a horizontal axis.
Further, the cage 5 has a horizontal support member 5a extending horizontally at both ends in the longitudinal direction thereof, and a plurality of free rollers 5b fixed to the horizontal support member 5a and freely rotating about a horizontal axis.
Both ends of the pallet 2 in the longitudinal direction are supported by free rollers 4b and 5b, and the pallet 2 traverses horizontally (vertically in the figure).

In FIG. 4, the turning positions of the engaging dock 26 are indicated by A, B, C, D, and E.
The turning position A is a standby position in which the engaging dock 26 is not engaged with the dock rail 2a.
When the engaging dock 26 turns from the turning position A (standby position) to the turning position B (engagement start position), the engaging dock 26 engages with the dock rail 2a of the lower pallet 2 in the figure.

By turning the engaging dock 26 to the right in the figure from the turning position B to the turning position D (position on the cage), the pallet 2 can be traversed on the cage from the lower side in the figure. This operation is called "palette capture".
At the time of "pallet uptake", the pallet 2 is guided in the width direction (vertical direction in the figure) by the free roller 4b provided on the storage shelf 4 and the free roller 5b provided on the cage 5.
In the state where the engaging dock 26 is engaged with the dock rail 2a at the turning position D, the pallet 2 does not protrude from the cage 5, and the cage 5 can be moved up and down as it is.
In the case of "pallet take-in" in which the pallet 2 is traversed from the upper side onto the cage in the figure, the turning direction is opposite to the above (turning to the left).

When the pallet 2 is traversed from above the cage to the lower storage shelf 4 in the figure, the engaging dock 26 is turned left in the figure from the state where the engaging dock 26 is engaged with the dock rail 2a at the turning position D. Then, the pallet 2 can be traversed to the lower storage shelf 4 in the figure. This operation is called "pallet payout".
When the engaging dock 26 turns to the turning position B, the engaging dock 26 is disengaged from the dock rail 2a, and the engaging dock 26 can return to the turning position A while leaving the pallet 2 on the storage shelf 4.
In the case of "pallet payout" in which the pallet 2 is traversed from the cage to the upper storage shelf 4 in the figure, the turning direction is opposite to the above (right turning).

In FIG. 4, the pallet fall prevention device 30 according to the present invention has a plurality of fall prevention levers 32.
The fall prevention levers 32 are provided at both ends in the longitudinal direction on the moving path side (in this example, the hoistway side) of each storage shelf 4. Therefore, in this example, two fall prevention levers 32 are provided on each storage shelf 4, and they are configured to be opposite (symmetrical) in the width direction and the length direction, respectively.

FIG. 5 is a view taken along the line BB of FIG. In this figure, the right side is the storage shelf 4 and the left side is the cage 5. This figure shows a state in which the cage 5 is stopped at a height traversing the pallet 2 facing the storage shelf 4 on the right side.

In FIG. 5, the pallet 2 has a stopper pin 2b extending horizontally in the longitudinal direction at the longitudinal end of the moving path side (in this example, the hoistway side). The stopper pin 2b has a flat plate shape in this example, but may have another shape, for example, a rod shape.
The fall prevention lever 32 can swing up and down in the drawing around the rotation shaft 33 between the locking position F and the releasing position G, and abuts on the stopper pin 2b at the locking position F on the moving path side of the pallet 2. The movement to (hoistway side) is blocked, and the contact with the stopper pin 2b is released at the release position G.
Further, the fall prevention lever 32 is urged to the locking position F by the spring 34. The storage shelf 4 is provided with a stopper 4c so as to hold the rotation of the fall prevention lever 32 by the spring 34 at the locking position F.

In FIG. 4, the pallet fall prevention device 30 according to the present invention further includes a plurality of lever release devices 40.
The lever release device 40 is provided with one set on each side of the cage 5 in the width direction (two sets in total). The lever release device 40 has a function of moving the fall prevention lever 32 from the locking position F to the release position G by turning the traverse arm 22.

In FIG. 4, the traverse arm 22 has a release roller 28 fixed to the lower portion thereof and extending in the vertical direction.
The lever release device 40 has a release lever 42 and a release pusher 50.
The release lever 42 comes into contact with the release roller 28 and swings around the swing vertical shaft 43. In this example, the two lever release devices 40 are configured to be opposite (symmetrical) in the width direction.
In this example, two release pushers 50 are provided on each release lever 42 at positions facing the fall prevention levers 32 at both ends in the longitudinal direction on the hoistway side. Further, the two release pushers 50 at both ends in the longitudinal direction are configured to be opposite (symmetrical) in the longitudinal direction.

In FIG. 5, the release pusher 50 projects toward the adjacent storage shelf side due to the swing of the release lever 42, abuts on the fall prevention lever 32, and moves the fall prevention lever 32 from the locking position F to the release position G.
In this figure, the release pusher 50 has a pair of parallel links 52a, 52b, a pusher body 54, and a spring 56.

The pair of parallel links 52a and 52b are fixed to the horizontal support member 5a via a pair of horizontal shafts 57, and are fixed to the pusher main body 54 via a pair of horizontal shafts 58. The distance between the pair of horizontal axes 57 and the pair of horizontal axes 58 is the same, and the distance between the horizontal axes 57 and the horizontal shafts 58 is also the same. Further, in this example, the pair of horizontal axes 57 are located horizontally in the transverse direction of the pallet 2.
With this configuration, the pusher main body 54 can be moved to the protruding position H and the returning position I (positions shown in the figure) protruding toward the storage shelf side while always holding the pusher main body 54 horizontally.

In this example, the end of the control cable 49 is fixed to the lower end of the parallel link 52a below the horizontal axis 57, and the pusher body 54 is moved between the protruding position H and the returning position I by moving the control cable 49. It is designed to do.

The control cable 49 includes an elongated hollow pipe and a cable inserted inside the control cable 49. The hollow pipe is fixed along a predetermined path in the cage, and the cable is movable along the inside of the hollow pipe in the length direction thereof. The control cable 49 is similar to, for example, a bicycle brake cable.

Further, in this example, the spring 56 is installed between the parallel link 52b and the horizontal support member 5a, and the parallel link 52b is always urged to the return position I side.

In FIG. 4, the release lever 42 and the release pusher 50 are connected to each other by a control cable 49 and are interlocked with each other. That is, one end of the two control cables 49 is fixed to the single release lever 42, and the other ends of the two control cables 49 are fixed to two release pushers 50 adjacent to the same storage shelf 4.
Therefore, the movement of the release lever 42 and the movement of the release pusher 50 by the control cable 49 are interlocked with each other.

FIG. 6 is an explanatory view of the release lever 42, and shows the release lever 42 on the lower side of FIG.
In this figure, the release lever 42 has a disc-shaped or semi-disc-shaped cable moving wheel 41 that can rotate around a swinging vertical shaft 43 fixed to the upper surface of the cage 5.
One ends of the two control cables 49 are fixed to the outer edge of the cable moving ring 41, and the control cable 49 is moved in the length direction by the rotation of the cable moving ring 41.

In this figure, the release lever 42 further includes a second drive lever 44, a first drive lever 45, and a spring 46.

In this figure, the positions shown by the solid lines of the second drive lever 44 and the first drive lever 45 are the return positions I of the release pusher 50, and the positions shown by the broken lines are the protrusion positions H of the release pusher 50.
The second drive lever 44 is a flat plate-shaped member whose end portion is fixed to the cable moving wheel 41 and extends horizontally in the length direction (right side in the figure) of the pallet 2 at the return position I, and is attached to the tip end portion thereof. It has an auxiliary vertical shaft 48.

The end of the first drive lever 45 is connected to the second drive lever 44 via the auxiliary vertical shaft 48, and the first drive lever 45 can rotate about the auxiliary vertical shaft 48. Further, the first drive lever 45 is a flat plate-shaped member that extends horizontally inward (upper in the figure) in the width direction of the pallet 2 at the return position I, and its tip portion is located on the rotation locus of the release roller 28.

Both ends of the spring 46 are tension springs fixed to an intermediate portion of the first drive lever 45 and an end portion of the second drive lever 44, respectively.
A stopper 47a is fixed to the second drive lever 44 so that the angle formed by the second drive lever 44 and the first drive lever 45 does not become smaller than a predetermined angle (about 90 ° in this example). ..
Further, a stopper 47b is fixed to the upper surface of the cage 5, and the second drive lever 44 is positioned at a predetermined return position I (in this example, the length direction of the pallet 2) at the return position I. There is.

According to the above configuration, when the transverse arm 22 turns downward in the drawing, the release roller 28 turns horizontally from the standby position a through the operation start position b to the operation end position c.
At the operation start position b, the release roller 28 contacts the tip of the first drive lever 45, and the release lever 42 swings around the swing vertical shaft 43 until the operation end position c, and the release lever at the operation end position c. Stay away from 42.
The swing of the release lever 42 from the operation start position b to the operation end position c causes the cable moving wheel 41 to rotate counterclockwise in the figure, and this rotation moves the control cable 49 in the length direction (H direction in the figure). ..

When the release roller 28 is separated from the release lever 42 at the operation end position c, the control cable 49 is urged to the return position I side, so that the release lever 42 moves to the right in the drawing centering on the swing vertical shaft 43. It swings and returns to the return position I by the stopper 47b.

For example, at the time of payout, when the release roller 28 turns left in the figure and returns to the standby position a, the release roller 28 comes into contact with the left side surface in the figure of the first drive lever 45. In this case, as shown in FIG. 7C described later, the release pusher 50 does not operate and is held at the return position I.
Therefore, in this example, the first drive lever 45 swings to the right in the drawing about the auxiliary vertical shaft 48 and retracts from the release roller 28 so as not to receive the operating force in the reverse direction by the release roller 28. ing.

The release lever 42 is not limited to this example, as long as it can come into contact with the release roller 28 and swing around the swing vertical shaft 43 to move the control cable 49 in the length direction (H direction in the figure). And may have other structures.

FIG. 7 is an operation explanatory view of the pallet fall prevention device 30.
In this figure, (A) shows the time when the pallet is prevented from falling, (B) shows the time when the pallet is taken in, and (C) shows the time when the pallet is discharged.
In FIG. 7A, the fall prevention lever 32 has a concave groove 32a, a release operating surface 32b, and a tapered surface 32c.

When the pallet is prevented from falling (A), the concave groove 32a abuts on the stopper pin 2b at the locking position F to prevent the pallet 2 from moving toward the cage side.
At the time of pallet loading (B), the release operating surface 32b moves the release prevention lever 32 from the locking position F to the release position G by moving the release pusher 50 toward the storage shelf.
At the time of pallet dispensing (C), the tapered surface 32c abuts on the stopper pin 2b due to the horizontal movement of the pallet 2 from the cage 5 (left side in the figure) to the storage shelf side, and the fall prevention lever 32 is released from the locking position F. Move to position G.

According to the above-described embodiment of the present invention, since the cage 5 has a lever release device 40 for moving the fall prevention lever 32 from the locking position F to the release position G by turning the traverse arm 22 by the traverse device 20, the pallet falls. There is no need for an actuator dedicated to the prevention device.

Further, since the lever release device 40 can be operated by the traversing device 20 without stopping the cage 5 on the stop floor by the soft landing mechanism, the soft landing operation is unnecessary.

Further, since the pallet 2 has the stopper pin 2b at the longitudinal end on the moving path side and the storage shelf 4 has the fall prevention lever 32 at the longitudinal end on the moving path side, other than the longitudinal end of the storage shelf 4. There is no member located in the middle of the moving path side of the upper and lower storage shelves 4, and there is no dead space between the upper and lower pallets 2 of the storage shelves 4. Therefore, there is no possibility that the traversing vehicle 1 and the fall prevention lever 32 interfere with each other, and the vehicle 1 having a high vehicle height can be stored without increasing the total height of the parking device.

Further, as described above, the present invention is not limited to the elevator type parking device 100, and can be applied to other mechanical parking devices.

It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the gist of the present invention.
