SUMMARY OF THE INVENTION A pallet lock device of the present invention comprises a shelf for mounting a pallet for mounting on a vehicle,
A pallet lock device in a multilevel parking facility comprising an elevator for raising and lowering this pallet, and a moving means for moving the pallet between the elevator and the shelves,
A stopper protruding laterally from the shelf and a contact member protruding downward from the pallet so that the pallet can contact the stopper in the horizontal direction at the contact position where the pallet is placed on the shelf. The elevator is provided with a connecting member that detachably connects the shelf and the pallet is movable on the shelf, and the connecting member is an abutting member when the pallet moves on the connecting member. Is configured to be pushed upward from the shelf so that the pallet is in the non-contact position over the stopper.

With this structure, when the pallet is on the shelf, the stopper and the contact member come into contact with each other to prevent the pallet from sliding off the shelf. Then, when the connecting member connects the shelf and the elevator, the contact member crosses the stopper as the pallet moves over the connecting member from the shelf to the elevator or from the elevator to the shelf. It is possible to easily transfer the pallet between the rack and the shelf. Further, the stopper is projected on the shelf, and the contact member is projected on the pallet. That is, since both are fixed, the structure is strong and simple, and the maintenance is easy.

Another pallet lock device of the present invention is a shelf for mounting a pallet for mounting on a vehicle, an elevator for moving the pallet up and down, and a moving means for moving the pallet between the elevator and the shelf. A pallet locking device in a multilevel parking facility comprising: a pallet that laterally abuts on the stopper at a contact position where the pallet is placed on the shelf and a stopper that projects laterally from the shelf. A contact member projecting downwardly from the elevator, and a connecting member disposed on the elevator or shelf that detachably connects the elevator and the shelf and on which the pallet can move. The connecting member pushes the pallet upward from the shelf so that the abutting member is in the non-abutting position over the stopper when the member is bridged between the shelf and the elevator. Is constructed sea urchin.

According to this structure, the pallet is prevented from slipping out of the shelf and has the same effect as the above-mentioned invention. Then, when the connecting member connects the shelf and the elevator, the pallet is pushed up and the contact member moves to the position beyond the stopper, so that the pallet can be easily transferred between the elevator and the shelf. Furthermore, since the stopper and the abutment member are not movable but are projected, they are strong and easy to maintain.

In the above pallet lock device, in which the connecting member is formed on the lower surface of the pallet in the pallet lock device in which the front and rear ends of the moving surface of the pallet of the connecting member are respectively formed with inclined portions inclined upward. It is easy to enter and the pallet on the shelf is easy to move onto the connecting member. As a result, the pallet can easily reach the non-contact position.

In the pallet lock device in which the contact member is in the non-contact position when the connecting member is bridged between the shelf and the elevator, the rack, the connecting member, and the elevator disposed on the pallet are placed above the shelf. The roller further includes a rolling roller and a recess formed on the upper surface of the shelf downwardly so that the roller can be engaged. When the roller engages with the recess, the pallet on the shelf contacts. The pallet is set to the non-contact position when the roller comes out of the recess and moves upward from the recess.When the connecting member connects the shelf to the elevator, the pallet is pushed up by pushing the roller upward. A pallet lock device configured to be in the abutting position is preferable.

This is because the pallet can be easily moved by the roller, and the two-stage locking mechanism is constituted by the engagement between the roller and the recess and the contact between the stopper and the contact member.

Further, the connecting member is attached to the elevator so that it can advance toward the shelf, and a roller is arranged on the connecting member. When the connecting member advances toward the shelf, the roller is provided. Even in the pallet lock device in which the pallet is in the non-contact position by contacting the lower surface of the pallet and pushing the pallet upward, the pallet can be easily moved.

The multi-level parking facility of the present invention comprises a shelf for mounting a pallet for mounting on a vehicle, an elevator for moving the pallet up and down, and a moving means for moving the pallet between the elevator and the shelf. One of the above-mentioned pallet lock devices for locking the pallet on the shelf is provided.

With this structure, the pallet can be prevented from sliding off the shelf.

When the connecting member of the pallet lock device connects the elevator and the shelf, the pallet mounting surface of the shelf and the pallet mounting surface of the elevator are arranged at substantially the same height position.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a pallet lock device and a multilevel parking facility according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 (a) is a front sectional view showing an embodiment of an elevator type multi-level parking facility of the present invention (hereinafter simply referred to as parking facility), and FIG. 1 (b) is a sectional view of FIG. 1 (a). I
It is a -I line sectional view.

In the parking facility 1 shown in FIG. 1, a pallet 2 on which a vehicle M is mounted is lifted and lowered by an elevator 3 to be stored.
It is something to get out. The elevator 3 has a substantially rectangular shape and moves up and down the hoistway 1a located in the center of the parking facility 1 in plan view. Wires (or chains) 4 as ropes are connected to the four corners of the elevator 3. The end portion of the wire 4 is connected to the counterweight 5, and the driving device 6 rotates the motor 6a in the forward and reverse directions to pull the wire 4 to drive the wire 4 to move up and down the elevator 3.

Pallet mounting shelves 8 are arranged on both sides of the hoistway 1a of the elevator 3 so as to form parking spaces 7 on the upper and lower floors, respectively. The shelf 8 is composed of beams extending at positions corresponding to the front end and the rear end of the pallet 2, and is fixed to a shelf column 8a standing on the floor. The shelves 8 are inclined so as to point very slightly upward toward the hoistway 1a. The elevator 3 moves up and down between the parking spaces 7 on both sides, moves to the floor of the designated parking space 7, and then pulls out the empty pallet 2 or the pallet 2 on which the vehicle M is mounted from the shelf 8 to enter the vehicle entry floor. Transport to. In this parking facility 1, the entry floor is the lowest floor (1
The floor). Elevator 3 has pallets 2 and shelves 8
There is provided a pallet moving device (not shown) for pulling out of the pallet and inserting it back into the shelf 8. As the pallet moving device, known devices such as a chain carrier type device disclosed in Japanese Patent No. 598708 and a crank arm type device disclosed in Japanese Patent Publication No. 7-33734 can be used.

When transferring the pallet 2 between the elevator 3 and the shelf 8, it is convenient to fix the elevator 3 so that the upper surface of the elevator 3 and the upper surface of the shelf 8 are substantially in the same horizontal plane. Therefore, as shown in FIG. 2, level adjusting devices 9 for fixing the elevator 3 are arranged at the four corners of the elevator 3. This level adjusting device 9 extends from the elevator 3 to the shelf 8 and connects the two when the elevator 3 reaches each of the shelves 8. When connected by the level adjusting device 9, the upper surfaces of the both 3 and 8 become the same level, and the pallet moving device can easily transfer the pallet 2 from one to the other. The level adjusting device 9 includes a connecting member 10 and an engaging roller 19, and also functions as a lock release mechanism 11b in a pallet lock device (hereinafter, simply referred to as a lock device) 11 as described later.

The parking facility 1 is provided with a lock device 11. The lock device 11 is provided to prevent a situation in which the pallet 2 placed on the shelf 8 slips on the shelf 8 and falls into the elevator hoistway due to vibration or the like. The locking device 11 is a pallet locking mechanism 1
1a and the lock release mechanism 11b are provided.

The locking device 11 is shown in detail in FIGS. 3 and 4. The pallet locking mechanism 11a is provided with a stopper 12 projecting from the side surface of the shelf 8, an abutting member 13 projecting downward from the pallet 2, and a recess 1 formed in the shelf 8.
It is composed of 5 and. Even if the pallet 2 on the shelf 8 slides toward the hoistway 1a, the contact member 13 contacts the stopper 12 and can stop. That is, the positional relationship between the recess 15 and the stopper 12 and the positional relationship between the roller 14 and the contact member 13, which will be described later, are the same as those of the recess 1
Before the roller 14 in 5 contacts the end of the recess 15 on the hoistway side, the stopper 12 and the contact member 13 contact each other. The portions 13a, 12a of the stopper 12 and the abutting member 13 that are in contact with each other are both vertical surfaces. Therefore, even when the both 12 and 13 come into contact with each other, a reaction force upward does not occur. That is, since a force component that pushes the pallet 2 upward is not generated, the contact member 13
Does not jump over the stopper 12 upward and the pallet 2 does not go out to the hoistway 1a. Furthermore, it is unlikely that an acceleration of 1 G or more will occur in the vertical direction due to an earthquake. This state is the lock state.

A plurality of rollers 14 are provided on the lower surface of the pallet 2.
Are provided (only one of these is shown),
The rollers 14 roll on the upper surface of the shelf 8, the moving surface that is the upper surface of the connecting member 10 and the upper surface of the elevator 3, so that the pallet 2 moves between the elevator and the shelf. As shown in FIG. 4, the width (thickness) of the roller 14 is substantially the same as the width of the shelf 8. The contact member 13 is mounted on both sides of the roller 14 so as to sandwich the shelf 8 so as to function as a guide member. The recess 15 is formed on the upper surface of the shelf 8 for the roller 14 to fall into. The recess 15 is formed at a position such that the roller 14 closest to the hoistway 1 a is fitted into the recess 15 when the pallet 2 is stored at a predetermined position on the shelf 8. Therefore, the hoistway 1a side of the pallet 2 is at a slightly lower position when it is stored at a predetermined position on the shelf than when it is rolling on the upper surfaces of the shelf 8 and the elevator 3.

The positional relationship between the stopper 12 and the contact member 13 is as follows. When the pallet 2 is stored in a predetermined position on the shelf, that is, the roller 14
When it is stuck in the recess 15, the contact member 13
Is in a position (contact position) where it can contact the stopper 12 in the horizontal direction. When the roller 14 comes out of the recess 15 and is on the upper surface of the shelf 8, the contact member 13 is in a position where it cannot contact the stopper 12 (non-contact position). In order to achieve such an effect, the depth h of the recess 15 is determined by the stopper 12 and the contact member 13.
Is larger than the overlapping dimension D in the vertical direction. In other words, from the dimension between the upper end T at the back of the notch of the connecting member 10 and the upper surface of the connecting member 10, the engagement roller 19 of the shelf 8 is determined.
The dimension obtained by subtracting the dimension between the upper end of the stopper and the bottom of the recess 15 is the vertical overlapping dimension D of the stopper 12 and the contact member 13.
Has been made larger. The vicinity of the tip of the shelf 8 including the formation portion of the recess 15 is narrowed. When the connecting member 10 to be described later advances, it overlaps with this narrow portion, and the total width of the narrow portion and the thickness of the connecting member 10 is the roller 14.
And the width of the shelf 8 are almost the same.

Next, an unlocking mechanism 11b for unlocking (unlocking) the pallet 2 and the shelf 8 will be described. As described above, the level adjusting device 9 is the lock release mechanism 11b. Connection member 1 in the unlocking mechanism 11b
0 is a beam in the lateral direction of the elevator 3 (longitudinal direction of the shelf 8),
So that its upper surface is flush with the upper surface of the elevator 3,
Further, it is provided so as to advance horizontally toward the shelf 8. The connecting member 10 has a horizontally elongated guide hole 1
6 is formed. On the other hand, two guide rollers 17 are attached to a bracket 17a fixed to the lower surface of the elevator 3 at intervals in the horizontal direction. The guide roller 17 is engaged with the elongated hole 16. Further, a drive cylinder 18 for advancing and retracting the connecting member 10 is attached to the elevator 3. An engagement roller 19 is attached near the end of the shelf 8 on the hoistway side. A notch 20 for engagement, which can be engaged with the engagement roller 19 when the connecting member 10 advances, is provided at the tip of the connecting member 10 on the shelf side.
Are formed. The width of the notch 20 on the inner side is substantially the same as the outer diameter of the engagement roller 19, but the notch 2
The tip open side of 0 is inclined so as to open. Due to the notch 20 whose tip is inclined and opened, even if there is a level difference between the upper surface of the elevator 3 and the upper surface of the shelf 8, as long as it is within the opening width of the tip of the notch 20, the connecting member 10 is not opened. When the engagement roller 19 is engaged with the back of the notch 20, the level of the upper surface of the elevator 3 and the level of the upper surface of the shelf 8 are made to coincide with each other.

As described above, the moving surface of the connecting member 10 is flush with the upper surface of the elevator 3, and further, a downwardly inclined portion 10a is formed at the tip of the shelf side thereof. Therefore, as shown in FIG. 5, when the connecting member 10 engages with the engagement roller 19, the inclined portion 10 a enters under the roller 14 and pushes up the roller 14. As a result, the lower end of the contact member 13 of the pallet 2 is the stopper 1
It is pushed up to a position above the upper end of 2. That is, the pallet 2 is in the non-contact position, and is in a state where it can be moved from the shelf 8 to the elevator 3 through the moving surface of the connecting member 10 by the pallet moving device. This is unlocking of the lock device 11.

Although the uppermost surface of the connecting member 10 is at the same level as the upper surface of the elevator, the present invention is not limited to this structure. Inclined portion 1 at the front and rear edges of the top surface as shown
If 0a and 10b are formed, the uppermost surface may be positioned higher than the upper surface of the elevator 3.

FIG. 6 shows a lock device 21 according to another embodiment. Also in this embodiment, the level adjusting device 22 is configured as the lock release mechanism 21b. In the level adjusting device 22 according to the present embodiment, the upper surface of the elevator 3 is positioned slightly higher than the upper surface of the shelf 8 when the elevator 3 is fixed to the shelf 8. Further, the pallet locking mechanism 21a is the pallet locking mechanism 11 of FIGS.
It has the same structure as a and has a stopper 12 projecting from the side surface of the shelf 8 and a contact member 1 projecting downward from the pallet 2.
3 and 3. This pallet locking mechanism 21a
Also in the above, both the portions 13a and 12a that are in contact with each other are vertical surfaces. Therefore, even when the both 12 and 13 come into contact with each other, a reaction force upward does not occur. A plurality of rollers 14 are arranged on the lower surface of the pallet 2 (only one of which is shown).

As shown in FIG. 6A, the width of the shelf 8 is approximately the same as the width of the roller 14 up to the tip. No recess 15 is formed on the upper surface of the shelf 8 for the roller 14 to fall into as shown in FIGS. The position of the pallet 2 placed on the upper surface of the shelf 8 is the contact position described above. As described above, the elevator 3 is fixed so that its upper surface is located slightly higher than the upper surface of the shelf 8, so that the pallet 2 is in the non-contact position when reaching the position of the upper surface of the elevator 3.

The connecting member 23 in the unlocking mechanism 21b
Is accommodated in the center of the lateral beam of the elevator 3 in the width direction so that it can horizontally advance toward the shelf 8. The connecting member 23 is formed with a horizontally elongated guide hole 16. On the other hand, two guide rollers 17 are attached at intervals in the horizontal direction so as to penetrate a portion of the elevator 3 that houses the connecting member 10. The guide roller 17 is engaged with the elongated hole 16. Further, a drive cylinder 18 for advancing and retracting the connecting member 23 is attached to the elevator 3. The moving surface of the connecting member 23 is, as shown in the drawing, a downwardly inclined portion 2 facing the tip thereof.
3a is formed, and a moving surface 23b having the same height as the upper surface of the elevator 3 is formed continuously with the inclined portion 23a.

A slit 24 is formed in the central portion of the shelf 8 in the width direction to receive the connecting member 23 that has advanced.
The slit 2 is provided near the end of the shelf 8 on the hoistway side.
The engagement roller 25 is attached so as to cross the path 4.
On the other hand, a notch 20 that can be engaged with the engagement roller 25 is formed at the tip of the connecting member 23 on the shelf side. This notch 2
No. 0 has the same structure as that of the connecting member 10 of FIGS.

As shown in FIG. 7, when the connecting member 23 engages with the engaging roller 25, the inclined portion 23a enters under the roller 14 and pushes up the roller 14 to move the pallet 2 onto the moving surface 23b. Put on. As a result, the pallet 2 is in the non-contact position. In order to achieve such an action, the drop H between the upper surface of the shelf 8 and the upper surface of the elevator 3 (moving surface of the connecting member) when the shelf 8 and the elevator 3 are connected is
It is larger than the vertical overlapping dimension D of the stopper 12 and the contact member 13. In other words, from the dimension between the upper end T behind the notch of the connecting member 23 and the moving surface 23b,
A dimension obtained by subtracting the dimension between the upper end of the engagement roller 25 of the shelf 8 and the upper surface of the shelf 8 is larger than the vertical overlapping dimension D of the stopper 12 and the contact member 13.

In the present lock device 21, the level is adjusted so that the upper surface of the elevator 3 is slightly higher than the upper surface of the shelf 8 as described above, but the present invention is not limited to this structure. For example, if the inclined surface 23c is formed on the rear surface of the connecting member 23 in addition to the inclined portion 23a at the front end as shown in the figure, the upper surface of the shelf 8 and the upper surface of the elevator 3 can be adjusted at the time of level adjustment. It is possible that and are on the same plane.

8 and 9 show a lock device 31 according to different embodiments. Also in this embodiment, the level adjusting device 32 is configured as the lock release mechanism 31b. In the level adjusting device 32 in this embodiment, when the elevator 3 is fixed to the shelf 8, the upper surface of the shelf 8 and the upper surface of the elevator 3 are at the same height position. Also,
In this embodiment, a sled (sliding plate) 33 is attached to the lower surface of the pallet 2 instead of the roller. As shown in FIG. 9, the shelf 8 is composed of two plate members arranged in parallel, and the central portion in the width direction of the shelf 8 (between the plate members).
There are provided a plurality of rollers 34 on which the sled 33 of the pallet 2 rides and moves. The lateral beams of the elevator 3 are also provided with a plurality of rollers 35 for the sled 33 of the pallet 2 to ride on and move. Further, as will be described later, a plurality of rollers 37 for moving the sled 33 on the upper surface of the connecting member 36 are also arranged.

The pallet locking mechanism 31a is composed of a step 38 as a stopper formed on the upper surface of the shelf 8 and an abutting member 39 projecting downward on both sides of the sled 33 of the pallet 2. . The step 38 is formed as a convex portion 40 near the tip of the shelf 8. The portions 38a and 39a where the step 38 and the contact member 39 contact each other are both vertical surfaces. Then, when the pallet 2 is on the roller 34 of the shelf 8, the position of the pallet 2 is the abutting position where the abutting member 39 and the step 38 can abut.

The connecting member 36 in the unlocking mechanism 31b
Is a shelf 8 at the center of the lateral beam of the elevator 3 in the width direction.
It is housed so that it can move horizontally toward.
The connecting member 36 is formed with a horizontally extending guide long hole 16, and two guide rollers 17 fixed to the elevator 3 at a horizontal interval are engaged with the long hole 16. . Further, a drive cylinder 18 for advancing and retracting the connecting member 36 is attached to the elevator 3.
An engagement roller 41 is attached near the hoistway side end of the shelf 8 so as to extend over both plate members. On the other hand, a notch 20 that can be engaged with the engagement roller 41 is formed at the tip of the connecting member 36 on the shelf side. The notch 20 has the same structure as the connecting member 10 shown in FIGS.

As shown in FIG. 10, when the notch 20 of the connecting member 36 engages with the engaging roller 41 of the shelf 8 to connect the shelf 8 and the elevator 3, the roller 37 of the connecting member 36.
The upper end of the rack 8 is higher than the upper end of the roller 34 of the shelf 8 by a dimension L. The height difference L is larger than the vertical overlapping dimension D of the step 38 and the contact member 39. In other words, the connecting member 3
From the dimension between the upper end T of the back of the notch 6 and the upper end of the roller 37, the upper end of the engaging roller 41 of the shelf 8 and the roller 3 of the shelf 8 are determined.
4 is larger than the vertical overlapping dimension D of the step 38 and the contact member 39. Therefore, when the connecting member 36 advances and engages with the engaging roller 41, the roller 37 of the connecting member 36
Pushes up the lower surface of the warp 33 of the pallet 2 by the dimension L to raise the pallet 2 to the non-contact position.

All the lock release mechanisms 11b described above,
The connecting members 10, 23, 36 in 21b, 31b are
When engaged with the shelf 8, the pallet 2 is lifted to the non-contact position. However, the present invention is not limited to such a configuration. Even if the pallet has not reached the non-contact position when the connection member engages with the shelf, the pallet may reach the non-contact position before contacting the stopper in the process of moving on the connection member. It is also easy to configure. For example, in FIG. 3, the recess 15 is formed to be long in the longitudinal direction of the shelf 8, and the predetermined position where the pallet 2 should be placed on the shelf 8 is set at the back of the shelf 8. This is facilitated by fixing the shelf 8 so as to be inclined slightly upward toward the hoistway 1a as described above. If the shelf 8 is configured in this way, the connecting member 10 can be attached to the shelf 8
The pallet 2 is moved to the non-contact position during the movement by pulling the pallet toward the elevator 3 by the moving device after the pallet 2 is engaged with the contact member 13 and can cross the stopper 12.

In the locking device shown in FIG. 6 and the locking device shown in FIG. 8, it is possible to similarly perform the same operation by placing the pallet at the back of the shelf 8.

In the embodiment of FIGS. 3 and 6, the connecting member 1
0 and 23 are provided in the elevator, and the engagement rollers are also 19.
25 are provided on the shelves. However, the present invention is not limited to such a configuration. The connecting members 10 and 23 are provided on the shelf,
The engagement rollers 19 and 25 may be provided in the elevator.
For example:

Inclined portions are formed at the front and rear ends of the moving surfaces of the connecting members 10 and 23, respectively. Then, the connecting member is housed on the back side of the shelf from the roller 14 closest to the elevator of the pallet on the shelf. Then, if the connecting member is advanced toward the elevator, the connecting member can push up the pallet to the non-contact position.

In the above embodiment, the level adjusting device is used as the lock releasing mechanism (lock releasing mechanism). That is, the configuration is such that both the level adjustment and the lock release can be performed. However, the present invention is not limited to such a configuration. A conventional level adjusting device may be provided separately from the locking device of the present invention.
