Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a pallet lock device, a vehicle elevating device having the pallet lock device, and a mechanical parking facility having the vehicle elevating device. More specifically, the present invention relates to a pallet lock device for fixing a pallet for mounting on a vehicle on a vehicle elevating device, as well as a vehicle elevating device and a mechanical parking facility.
[0002]
2. Description of the Related Art
As a conventional pallet lock device, for example, a lock device disclosed in Japanese Utility Model Publication No. 3-55718 is known.
[0003]
This pallet lock device includes a rocking body having a pallet locking portion provided on an elevating floor for elevating and lowering the pallet, and a movable base for moving the pallet to the elevating floor and the parking floor. The movable platform is provided so as to be able to advance from the elevator floor to the parking floor, and the pallet is moved by the chain conveyor from the elevator floor to the parking floor and from the parking floor to the elevator floor. In other words, the movable platform is a horizontal pallet transport device.
[0004]
In the vicinity of the side of the elevating floor, a rocking body having a pallet locking portion for locking to the pallet for positioning is provided. When the pallet is placed on the elevating floor, the pallet locking portion is locked on the side of the pallet. When the movable platform advances toward the parking floor, the action section of the movable platform engages with the lever of the rocking body to push down the pallet locking section, thereby releasing the locking with the pallet.
[0005]
However, in order to release the lock between the pallet locking portion and the pallet, it is necessary to advance the horizontal transport device toward the parking floor. Such a lateral transport device needs to be provided at the front and rear ends of the elevating floor corresponding to the front and rear ends of the pallet. As a result, the structure of the lift floor becomes complicated and the weight increases. Further, since the rocking member is elastically locked to the pallet by a biasing means including a spring, there is a problem that the locking force is reduced by an external force such as an earthquake.
[0006]
The present invention has been made to solve such a problem, and has a pallet lock device capable of positioning a pallet on the lifting device with a simple configuration and releasing the pallet, and a vehicle including the pallet lifting device. It is an object of the present invention to provide an elevator device and a mechanical parking facility provided with a vehicle elevator device.
[0007]
[Means for Solving the Problems]
The pallet lock device of the present invention
A connecting member that is disposed on an elevating device that raises and lowers the pallet, detachably connects the elevating device and a parking shelf on which the pallet is mounted, and on which a pallet can move,
A pallet locking member disposed on the lifting device, the pallet locking member being displaceable between an operating position for locking the pallet and a non-operating position where the pallet cannot be locked;
A drive member disposed on the connection member, displacing the pallet locking member to a non-operation position as the connection member connects the parking shelf and the elevating device, and displacing to the operation position as the connection is released; and It has.
[0008]
With this configuration, when the pallet is placed on the lifting device, the lifting device reaches the designated parking shelf, and the connecting member simply connects the shelf and the lifting device to release the pallet lock on the lifting device. Also, the pallet on the lifting device is locked by simply releasing the connection between the shelf and the lifting device. As described above, the pallet lock and the release thereof can be performed by skillfully using the connecting member, which is an essential member of the lifting device.
[0009]
And the connecting member is configured to connect the parking shelf and the elevating device by advancing toward the parking shelf, and the pallet engaging member has an engaging portion at an end on the parking shelf side. And the locking portion is swingably mounted so as to be displaced between an upper working position and a lower non-working position, and the driving member moves the locking portion together with the advancement of the connecting member. Pallet locking devices that operate to lower to a non-working position are preferred. This is because the configuration becomes simple.
[0010]
Further, the pallet locking member has a base portion formed on the opposite side of the locking portion, a pivot portion pivotally supported by an elevating device formed between the locking portion and the base portion, The driving member has an upper end edge which moves while being in contact between the locking portion and the base portion with the advance and retreat, and the upper edge portion is concavely curved from the base portion to the locking portion. A pallet lock device in which the vicinity of the parking shelf side end constitutes a locking portion is preferred. This is because the driving member can drive the pallet locking member only by being in contact with the pallet locking member, so that the configuration is further simplified. This is because if the driving member moves while contacting the upper edge of the concavely curved pallet locking member as the connecting member advances and retracts, the driving member necessarily pushes down the locking portion.
[0011]
Further, it is preferable that the pallet locking member has a pallet lock device in which the weight on the locking portion side with respect to the pivot portion is larger than the weight on the base portion side. This is because the pallet locking member descends to the non-operating position by its own weight by the drive member moving from the base side of the pallet locking member to the locking portion side beyond the pivotal support portion, and the structure is further simplified by such action. This is because that.
[0012]
In the vehicle elevating device according to the present invention, any one of the pallet lock devices described above is disposed near the four corners of the elevating device, and the pallet on the elevating device is positioned in the lateral direction by each pallet locking member. It is configured to:
[0013]
With this configuration, the same operation and effect as described above can be obtained.
[0014]
The mechanical parking equipment of the present invention includes the above-described vehicle elevating device of the present invention, and a plurality of stages of vehicle parking shelves provided on both sides of the hoistway of the vehicle elevating device.
[0015]
With this configuration, the same operation and effect as described above can be obtained.
[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of a pallet lock device, a vehicle elevating device and a mechanical parking facility of the present invention will be described with reference to the accompanying drawings.
[0017]
FIG. 1 illustrates an elevator-type multi-story parking facility (hereinafter simply referred to as parking facility). FIG. 1A is a front sectional view thereof, and FIG. 1B is a sectional view taken along line II of FIG. 1A.
[0018]
In the parking facility 1, a pallet 2 on which a vehicle M is mounted is moved up and down by an elevator 3 to be accommodated and taken out. The elevator 3 has a substantially rectangular shape and moves up and down the hoistway 1a located at the center of the parking facility 1 in plan view. Wires (or chains) 4 are connected to the four corners of the elevator 3 as ropes. The end of the wire 4 is connected to a counterweight 5, and the drive unit 6 rotates the motor 6a in the normal and reverse directions, thereby pulling and driving the wire 4 to move the elevator 3 up and down.
[0019]
Pallet mounting shelves (parking shelves) 8 are arranged on both sides of the hoistway 1a of the elevator 3 so as to form parking spaces 7 on upper and lower floors. 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 8a standing on the floor. The shelf 8 is inclined so as to be 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 designated parking space 7 floor, then pulls out the empty pallet 2 or the pallet 2 on which the vehicle M is mounted from the shelf 8 and enters and exits the floor. Transport to In this parking facility 1, the entrance / exit floor is the lowest floor (the first floor). The elevator 3 is provided with a pallet moving device, described later, for pulling out the pallet 2 from the shelf 8 and inserting it back into the shelf 8. As the pallet moving device, known devices such as a chain carrier type disclosed in Japanese Patent No. 598708 and a crank arm type disclosed in Japanese Patent Publication No. 7-33734 can be used. It is preferable that the pallet also has a pallet turning function to be described later (see FIGS. 11 to 14).
[0020]
When the pallet 2 is transferred between the elevator 3 and the shelf 8, it is convenient to fix the elevator 3 so that, for example, the upper surface of the elevator 3 and the upper surface of the shelf 8 are substantially in the same horizontal plane. For this purpose, as shown in FIG. 2, at the four corners of the elevator 3, level adjusters 9 for fixing the elevator 3 to the shelf 8 and positioning the elevator 3 in the vertical direction are provided. The level adjusting device 9 includes a connecting member 10 provided on the elevator 3 and a first engaging roller 13 provided on the shelf 8. The connecting member 10 extends from the elevator 3 to the shelf 8 when the elevator 3 reaches each shelf 8 and engages with the first engagement roller 13 to connect the two 3 and 8. When connected by the level adjusting device 9, the upper surfaces of the two 3 and 8 are at the same level, and the pallet 2 can be easily transferred from one to the other by the pallet moving device. As described later, the connecting member 10 also functions as a lock release mechanism in pallet lock devices (hereinafter, simply referred to as lock devices) 11 and 12.
[0021]
Here, the lock device refers to a first lock 11 for fixing the pallet 2 on the elevator 3 and a second lock 12 for fixing the pallet 2 on the shelf 8. Each of the locks 11 and 12 is provided to prevent the mounted pallet 2 from slipping on the elevator 3 or the shelf 8 due to vibration or the like and inadvertently moving. .
[0022]
The first lock device 11 and the connecting member 10 as a first lock release mechanism thereof will be described with reference to FIGS. 3, 4, and 5. FIG. The pallet 2 has rollers 14 for traversing on the lower surfaces at the front and rear ends. When the pallet 2 traverses, the traversing rollers 14 roll on the traveling path on the elevator 3, the upper surface of the connecting member 10 and the traveling path on the shelf 8.
[0023]
A pallet locking member (hereinafter simply referred to as a locking member) 15 is attached to each of the left and right front and rear ends of the elevator 3 by pins 16 so as to be swingable. 7 and 8, the locking member 15 is pivotally supported at an intermediate portion in the thickness direction of the beam forming the elevator 3. The first lock 11 includes the locking member 15 and a driving projection 23 described later. The locking member 15 has an upper surface curved in a substantially J-shape. Of course, it may be curved substantially in an L shape, or may be curved in an arc shape. The vicinity of the leading end of the locking member 15 on the shelf side, that is, the portion where the upper surface stands up forms a locking portion 17 with which the traversing roller 14 is locked. The position where the locking portion 17 is locked to the traversing roller 14 is the operation position for the locking member 15 and the locking portion 17. In order to more securely lock the locking portion 17 to the traversing roller 14, the shape of the locking portion 17 in the operation position is such that the upper end of the locking portion 17 is higher than the center position of the traversing roller 14 as shown in the drawing. do it.
[0024]
In addition, the vicinity of the end on the opposite side of the locking portion 17 is a base 18. The upper surface is formed linearly from the end of the base 18 to the engaging portion 17 via the pivotal support 16. The weight of the locking member 15 on the locking portion side with respect to the pivot portion 16 is larger than the weight on the base portion side. Therefore, unless the locking member 15 is supported by an external force, the locking member 17 rotates to lower the locking portion 17 side (FIG. 4), so that the locking member 15 is in a non-operating position where it cannot lock with the traversing roller 14. A stopper pin 21 that abuts on the locking member 15 is protruded from a member of the elevator 3 so that the rotation of the locking member 15 stops at a predetermined position.
[0025]
On the other hand, the connecting member 10 is provided on a beam in the lateral direction of the elevator 3 (longitudinal direction of the shelf 8) so that the upper surface thereof is flush with the upper surface of the elevator 3, and extends horizontally toward the shelf 8. It is provided in. The connecting member 10 has a guide elongated hole 19 extending horizontally. On the other hand, two guide rollers 20 are attached to a bracket 20a fixed to the lower surface of the elevator 3 at a horizontal interval. The guide roller 20 is engaged with the elongated hole 19. Further, a drive cylinder 22 for moving the connecting member 10 forward and backward is attached to the elevator 3. In addition, a drive projection 23 is provided on the side surface of the connecting member 10 to protrude. The driving projection 23 is in contact with the upper surface of the locking member 15. In a state where the connecting member 10 is housed in the elevator 3, the driving projection 23 is in contact with the upper surface of the base 18 of the locking member 15, so that the locking member 15 rotates and the locking portion 17 does not act. It is prevented from falling into position (FIG. 3).
[0026]
Since the first locks 11 are installed at the four corners of the elevator 3, the pallet 2 is positioned on the elevator 3 in a stable state with the traversing rollers 14 on the left and right sides positioned from outside by the locking members 15 as shown in FIG. And is prevented from inadvertently traversing. This is the first locked state.
[0027]
In addition, the elevator 3 is provided with a pallet turning device (hereinafter, simply referred to as a turning device) 30 that operates only on the entrance / exit floor of the parking facility. When the pallet is turned by the turning device 30, the pallet 2 lifts the pallet 2 slightly upward from the pallet mounting surface of the elevator 3, turns the pallet by 180 °, and then mounts the pallet 2 on the pallet mounting surface again. When the pallet is re-mounted, even if the pallet slightly displaces from the initial position as shown by the two-dot chain line in FIG. Since the rollers 14 are guided, the pallet 2 is positioned at a predetermined position. This is because the distance between the upper ends of the left and right locking portions 17 is larger than the distance between the outer ends of the left and right traversing rollers 14 as shown in the figure. The reason is that the upper surface of the locking portion 17 draws a smooth curve.
[0028]
As shown in FIG. 4, as the connecting member 10 advances toward the shelf 8, the driving projection 23 slides on the upper surface of the locking member 15, and when the driving projection 23 passes through the pivot point 16, the locking member 15 is moved to the driving projection 23. And the locking member 15 rotates, and the locking portion 17 is lowered to the non-operating position. Then, the traversing rollers 14 of the pallet 2 are unlocked (unlocked), so that the pallet 2 is moved to the shelf 8 by a moving device (not shown). In the inoperative position of the locking portion 17, the upper end of the locking portion 17 is located below the path along which the driving protrusion 23 passes as well as the rolling path of the traversing roller 14. Does not interfere. Therefore, as shown in FIG. 5, as the connecting member 10 retreats toward the elevator 3, the driving projection 23 first contacts the base 18 of the locking member 15 to rotate the locking member 15. Thereby, the locking portion 17 is raised to the operation position.
[0029]
FIG. 10 shows a case where the pallet 2 placed on the shelf 8 is transported to the elevator 3. As described above, when the connecting member 10 is advanced toward the shelf 8, the locking member 15 is rotated, and the locking portion 17 is lowered to the non-operating position. Then, the traversing roller 14 can roll onto the elevator 3 from the shelf 8 via the upper surface of the connecting member 10 without interfering with the locking member 15. When the pallet 2 moves onto the elevator 3, the right end of the pallet is positioned because the locking member on the right side of the elevator (not shown) is in the operating position. Next, since the left locking member 15 returns to the operating position by the retreat of the left connecting member 10 shown in the figure, the left and right pallets 2 are positioned and stabilized (FIG. 9).
[0030]
The illustrated locking member 15 has a banana shape as a whole, but is not particularly limited to this shape. The important point is that the driving projection 23 has an upper surface that can slide smoothly, and one end of this upper surface constitutes a locking portion that can lock the traversing roller 14. Therefore, it is preferable that the upper surface has a J-shape and a smooth L-shape as a whole.
[0031]
Next, the operation of the second lock 12 on the shelf 8 and the operation of the connecting member 10 as a lock release mechanism will be described with reference to FIGS. 3, 4, and 5. FIG. The second lock 12 is formed on a top surface of the shelf 8, a stopper 27 protruding from a side surface of the shelf 8, a contact member 28 protruding downward from the pallet 2 and capable of contacting the stopper 27. And a recess 29 into which the traversing roller 14 fits. Even if the pallet 2 on the shelf 8 slides toward the hoistway 1a, the contact member 28 can contact the stopper 27 and stop.
[0032]
That is, the positional relationship between the recess 29 and the stopper 27 and the positional relationship between the traversing roller 14 and the contact member 28 are determined before the traversing roller 14 in the recess 29 contacts the hoistway-side end of the recess 29. 27 and the contact member 28 are in contact with each other. Both parts 27a and 28a of the stopper 27 and the contact member 28 that contact each other are vertical. Therefore, even when the two 27 and 28 come into contact with each other, no upward reaction force is generated. That is, since no force component is generated to push the pallet 2 upward, the contact member 28 does not jump over the stopper 27 and the pallet 2 does not go out to the hoistway 1a. Furthermore, it is unlikely that an acceleration of 1 G or more is generated in the vertical direction due to the earthquake. This state is a second lock state.
[0033]
As shown in FIGS. 6 to 8, the width (thickness) of the traversing roller 14 is substantially the same as the width of the shelf 8. The abutting members 28 are attached to both sides of the traversing roller 14 so as to function as guide members with the shelf 8 interposed therebetween. The recess 29 is formed at a position where the traversing roller 14 closest to the hoistway 1a fits when the pallet 2 is stored at a predetermined position on the shelf 8. Therefore, the hoistway 1a side (elevator side) of the pallet 2 is at a slightly lower position when it is stored in a predetermined position on the shelf than when rolling on the upper surface of the shelf 8 or the elevator 3.
[0034]
The positional relationship between the stopper 27 and the contact member 28 is as follows. When the pallet 2 is at a predetermined position on the shelf, that is, when the traversing roller 14 is stuck in the recess 29, the contact member 28 is at a position (contact position) where it can contact the stopper 27 in the horizontal direction. is there. When the traversing roller 14 comes out of the recess 29 and is on the upper surface of the shelf 8, the contact member 28 is at a position where it cannot contact the stopper 27 (non-contact position).
[0035]
In order to achieve such an effect, as shown in FIG. 5, the depth h of the recess 29 is made larger than the vertical overlapping dimension D of the stopper 27 and the contact member 28. In other words, the distance between the upper end T of the first engaging roller 13 of the shelf 8 and the bottom of the recess 29 is determined based on the dimension between the upper end T of the notch 26 of the connecting member 10 and the upper surface of the connecting member 10. The reduced dimension is larger than the vertical overlapping dimension D of the stopper 27 and the contact member 28. The vicinity of the tip of the shelf 8 including the formation of the recess 29 is narrowed. When the connecting member 10 advances, it overlaps the narrow portion, and the sum of the width of the narrow portion and the thickness of the connecting member 10 is approximately the same as the thickness of the traversing roller 14 and the width of the shelf 8. It becomes.
[0036]
Next, a second lock release mechanism for releasing the lock between the pallet 2 and the shelf 8 will be described. As described above, the connecting member 10 is the second lock release mechanism. A first engaging roller 13 is mounted near the end of the shelf 8 on the hoistway side. A notch 26 for engagement which can be engaged with the first engagement roller 13 when the connecting member 10 advances is formed at a tip of the connecting member 10 on the shelf side. The width of the notch 26 at the back is substantially the same as the outer diameter of the first engagement roller 13, but the open end of the notch 26 is inclined to open. Even if there is a level difference between the upper surface of the elevator 3 and the upper surface of the shelf 8 due to the notch 26 whose tip is inclined and opened, as long as the level difference is within the open width of the tip of the notch 26, the connection member 10 When the first engagement roller 13 is engaged with the inside of the notch 26, the level of the upper surface of the elevator 3 and the level of the upper surface of the shelf 8 match (FIG. 4).
[0037]
As described above, the moving surface of the connecting member 10 is made to be flush with the upper surface of the elevator 3, and a downward inclined portion 10a is formed at the tip of the shelf side. Therefore, as shown in FIG. 10, when the connecting member 10 is engaged with the first engagement roller 13, the inclined portion 10 a enters below the traversing roller 14 and pushes up the traversing roller 14. Thereby, the pallet 2 is pushed up to a position where the lower end of the contact member 28 is higher than the upper end of the stopper 27. 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 the unlocking of the second lock 12.
[0038]
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 such a configuration. If the inclined portions 10a and 10b are formed at the front and rear ends of the uppermost surface as shown in the figure, the uppermost surface may be positioned higher than the upper surface of the elevator 3.
[0039]
11, 12 and 13 show the elevator 3 and the turning device 30 assembled to the elevator 3. FIG. 11 is a plan view showing the elevator 3, FIG. 12 is a vertical sectional view showing the elevator 3 in a state where the elevator 3 has landed on the entrance / exit floor E, and FIG. 3 is a vertical sectional view showing the elevator 3 of FIG.
[0040]
The elevator 3 includes a lift main body 31, a frame base 32 and a turning frame 33 integrated via a bearing 34. Therefore, the revolving frame 33 is configured to be revolvable with respect to the frame base 32. The frame base 32 and the lifting / lowering main body 31 are not allowed to pivot with respect to each other. As will be described later, the lifting / lowering main body 31 and the integrated body of the frame base 32 and the revolving frame 33 are assembled so as to be relatively displaceable in the vertical direction by a certain dimension (see FIGS. 12 and 13). .
[0041]
A pallet placing portion 43 for placing the pallet 2 is formed on the turning frame 33. A traversing rail 44 for placing the pallet 2 and guiding the pallet 2 on the elevating main body 31 is provided. The traversing rail 44 extends in the width direction of the elevating main body 31, and is positioned so as to be substantially continuous with the rail 42 of the shelf 8 when the elevator 3 stops at a predetermined position corresponding to the shelf 8. The frame base 32 is supported by the elevating body 31 so as to be vertically movable. When the elevator 3 descends to the entrance / exit floor E, the frame base 32 lands on the floor F in the pit and does not go down any further, but the elevating body 31 continues to descend slightly, so that the frame base 32 is moved up and down. Is slightly displaced upward by a certain dimension (FIG. 12). As a result, the pallet 2 is placed on the pallet placing portion 43 of the turning frame 33.
[0042]
Further, when the lifting / lowering main body 31 is lifted, the lifting / lowering main body 31 is slightly displaced upward relative to the frame base 32 by a certain dimension, and the traversing rollers 14 of the pallet 2 are placed on the traversing rails 44 of the lifting / lowering main body 31. (Figure 13).
[0043]
The traversing rollers 14 roll on the traversing rails 44 and the rails 42 of the shelf 8. The pallet placing portion 43 of the revolving frame 33 is shaped so that the lower surface of the pallet 2 directly rests thereon.
[0044]
The relative vertical movement between the frame base 32 and the elevating main body 31 can be easily understood by comparing FIG. 12 and FIG. It is the elevating body 31 that is actually lifted during elevating and lowering by contacting the abutting part 35 formed on the elevating body 31 with the frame base 32 as shown in FIG. The table 32 is lifted together with the turning frame 33. At this time, the elevating main body 31 is moving relatively upward with respect to the frame base 32. As shown in FIG. 12, when the elevator 3 is landing on the floor of the entrance / exit floor E, the frame base 32 is landing. That is, the frame base 32 is supported by the floor surface, so to speak, and the elevating main body 31 moves downward relative to the frame base 32 by its own weight.
[0045]
A turning drive for turning the turning frame 33 with respect to the frame base 32 is attached to the elevating body 31. This turning drive includes a first motor 36a and a second motor 36b. By these motors 36a and 36b, the revolving frame 33 is revolved via first and second revolving arms 37a and 37b which can reciprocate. That is, as will be apparent with reference to FIGS. 11 and 12, when the elevator 3 lands, the engaging projection 38 formed at the tip of the first pivot arm 37a and the engaging projection 38 formed at the pivot frame. Since the joint portion 39 is engaged, the turning arms 33a and 37b are turned so that the turning frame 33 turns. The engaged portion 39 has a shape that allows the engaging protrusion 38 to pass in the vertical direction, but does not allow relative movement in the rotation direction when engaged. This enables the turning device 30 to operate only when the elevator 3 lands on the entrance / exit floor E. The frame base 32, the turning frame 33, and the turning driving device constitute the turning device 30.
[0046]
Next, the aforementioned moving device for the elevator 3 to receive and return the pallets 2 from the shelves 8 will be described. The turning arms 37a and 37b perform the function of the moving device. That is, after the second engagement roller 40 provided at the tip of the second swing arm 37b is engaged with the engagement groove 41 (see FIG. 13) provided on the lower surface of the pallet 2, the swing arm 37a, The pallet is traversed by turning the 37b. As shown in FIGS. 13 and 14, the engagement groove 41 has a shape that allows the second engagement roller 40 to pass in the longitudinal direction of the pallet and does not allow relative movement in the pallet width direction (the transverse direction of the pallet).
[0047]
The pallet returning operation and the receiving operation (traversing operation) will be briefly described with reference to FIG. As shown in FIG. 14A, the first turning arm 37a is turned in a predetermined direction by the two motors 36a and 36b so that the angle between the turning arms 37a and 37b does not change, and the second engagement roller 40 Is engaged with the engagement groove 41. Next, as shown in FIG. 14B, the second engagement roller 40 is appropriately driven by the two motors 36a and 36b so as to move in the pallet width direction. Thus, the pallet 2 is traversed toward the shelf 8. As shown in FIG. 14C, when the pallet 2 is settled on the shelf 8, the second turning arm 37b is turned so that the first turning arm 37a does not rotate, and the second engaging roller 40 is moved from the engaging groove 41. Release (indicated by the two-dot chain line). When a pallet is received from the shelf 8, the two turning arms 37a and 37b are operated in the reverse procedure. The driving of the swing arms 37a and 37b is described in detail in Japanese Patent Application No. 2001-239116 filed by the present applicant.
[0048]
【The invention's effect】
According to the present invention, when a pallet is placed on the elevating device, the elevating device reaches the designated parking shelf, and the connecting member connects the shelf and the elevating device only by the pallet lock on the elevating device. The pallet on the lifting device is locked simply by releasing the connection between the shelf and the lifting device.
