[0006]

In both the prior art 1 and prior art 3 pallet lifting and lowering devices in the parking equipment, the stopper works when the pallet is at a fixed position. When the pallet is raised and lowered, it is necessary to release the stopper while the load on the pallet is being applied. In addition, in the prior art 1, the elevating chain is hung around the pallet, so that the installation space and the chain itself are uneconomical factors.

In the lifting device according to the prior art 2, the chain is freely hung by the weight of the engaging member attached to the end thereof. Therefore, when the drive sprocket is operated from a state in which the chain is slack, a time lag occurs in starting the movement of the chain until the slack is completely removed. Further, other lifting devices according to the prior art 2 must be provided with a mechanism such as a chain guide and an engaging means for gripping the chain.

In the lifting device according to the prior art 4, the upper pallet is directly raised and lowered by a chain, but the lower pallet is raised and lowered via a pulley (guide roll). Are greatly different from each other.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and a single drive means individually raises and lowers each of the upper and lower vehicle accommodation means by a short transmission means. There is no time lag at the start of driving due to the slack of the transmission means as described above, and no load is applied to the operation of the stopper as in the prior arts 1 and 3,
It is an object of the present invention to provide an elevating device in which the driving conditions do not change when the pallet is raised and lowered as in the prior art 4.

[0010]

SUMMARY OF THE INVENTION According to the present invention, there is provided an elevating device, comprising: a parking space; an upper housing means and a lower housing means which are arranged vertically in the parking space and which can move up and down; A first fixed pulley disposed in the upper part of the parking space, a first pulley disposed in the upper receiving means, a second pulley disposed in the lower receiving means, and supporting the upper receiving means from below. An engagement pulley that can be engaged and disengaged so as to perform, and a flexible transmission means for vertically moving the two storage means separately,
Driving means capable of moving the transmission means in its longitudinal direction;
At least a locking means for stopping and fixing the upper housing means at the ascending position, wherein the transmission means engages at least the engagement pulley from below with one end thereof fixed to the parking space portion. This was suspended, then engaged at least with the first fixed pulley from above, then engaged at least with the second pulley from below and suspended it, and then engaged with at least the first pulley from above. The other end is fixed to the parking space.

Therefore, when the upper storage means is at the upper position in the parking space and the lower storage means is at the reference position at the lower position in the parking space, the transmission means is set to a length which causes little slack. Become. Then, the lower pulley of the lower receiving means is lifted in a state where the upper receiving means is fixed to the upper row by the locking means, or if the transmission means is moved so as to descend, the lower receiving means can be raised and lowered. it can. At this time, when the lower storage means is located at a position other than the lower end, the engaging pulley detached from the upper storage means hangs down the slack of the transmission means by its own weight. When the lower storage means is located at the lower end, the transmission means hardly sags, and the engagement pulley engages with the upper storage means. In addition, if the transmission means is moved from the reference position so as to lower or lift the engagement pulley with the lock means released, the lower storage means lowers the upper storage means while being stationary at the lower end by its own weight.・ Can be raised.

That is, there is no time lag in the start of movement of the storage means because the transmission means on the side of the storage means to be lifted and lowered does not slack. Since both accommodation means are raised and lowered via the pulleys, the required torque and the required time for driving do not greatly differ between ascending and descending. Further, when the locking means is operated, the fifth pulley and the first pulley can be slightly lifted by the driving means, so that the load on the locking means with respect to the locking means can be released. In addition, the above operation can be achieved by the short transmission means.

According to another aspect of the present invention, there is provided a parking space, an upper housing means and a lower housing means which are vertically disposed in the parking space and which are capable of moving the vehicle up and down. The first fixed pulley disposed in the upper part of the space, the first pulley and the fifth pulley disposed in the upper receiving means, the second pulley disposed in the lower receiving means, and the two receiving means are separated. A transmission means having flexibility to move the transmission means up and down, a driving means capable of moving the transmission means in the longitudinal direction thereof, and a lock means for stopping and fixing the upper-stage accommodation means at least at the ascending position. A transmission means, one end of which is fixed to the parking space, is engaged with at least the fifth pulley from below to suspend it, and then is engaged with at least the first fixed pulley from above, and then at least Engage the second pulley from below Hanged les, then the other end after having engaged from above on at least the first pulley is fixed to the parking space.

Therefore, when the upper storage means is at the upper position in the parking space and the lower storage means is at the reference position at the lower position in the parking space, the transmission means is set to a length which causes little slack. Become. Then, the lower pulley of the lower receiving means is lifted in a state where the upper receiving means is fixed to the upper row by the locking means, or if the transmission means is moved so as to descend, the lower receiving means can be raised and lowered. it can. At that time, when the lower storage means is located at a position other than the lower end, the portion of the transmission means separated from the fifth pulley of the upper storage means is suspended by its own weight. When the lower housing means is located at the lower end, the transmission means engages with the fifth pulley with little slack. Also, if the transmission means is moved from the reference position to lower or lift the fifth pulley in a state where the locking means is released, the lower storage means lowers the upper storage means while being stationary at the lower end by its own weight.・ Can be raised.

That is, since the transmission means on the side of the storage means to be lifted and lowered does not slack, there is no time lag at the start of movement of the storage means. When the lower storage means is located at a position other than the lower end, the portion of the transmission means hangs down by its own weight as described above. However, since this is not a part on the side of the storage means (lower storage means) to be lifted and lowered, There is no time lag to start moving. Since both accommodation means are raised and lowered via the pulleys, the required torque and the required time for driving do not greatly differ between ascending and descending. Further, when the locking means is operated, the transmission means is moved in the direction in which the fifth pulley is lifted, so that the upper housing means can be slightly lifted, so that the load load of the housing means on the locking means can be released. It is possible. In addition, the above operation can be achieved by the short transmission means.

According to still another aspect of the present invention, there is provided a parking space and a vertically movable space disposed in the parking space.
Upper and lower accommodation means for accommodating a vehicle, a first fixed pulley and a second fixed pulley arranged at an upper part in the parking space, and a third fixed pulley arranged at a lower part in the parking space And a first pulley and a fourth pulley disposed in the upper receiving means, a second pulley and a third pulley disposed in the lower receiving means, and the flexibility of vertically moving the two receiving means separately. Transmission means, a driving means capable of moving the transmission means in the longitudinal direction thereof, and a lock means for stopping and fixing the upper housing means at least at the ascending position, the transmission means having one end parked. After being fixed to the space portion, it engages at least the third pulley from above, then engages at least the third fixed pulley from below, then engages at least the second fixed pulley from above, and then at least Fourth name To engage from below and suspend it, then engage at least the first fixed pulley from above, then engage at least the second pulley from below to suspend it, and then at least The other end is fixed to the parking space after engaging with one pulley from above.

Therefore, when the upper storage means is at the upper position in the parking space and the lower storage means is at the reference position at the lower position in the parking space, the lower storage means is fixed to the upper storage by the lock means. By moving the transmission means so as to raise or lower the second pulley of the means, the lower housing means can be raised and lowered. Also, if the transmission means is moved from the reference position to lower or lift the fourth pulley with the locking means released, the upper storage means rises while the lower storage means remains stationary at the lower end by its own weight.・ It can be lowered.

At this time, the transmission means hardly sags in all the states of the housing means. Therefore, there is no time lag at the start of the movement of the storage means, and the slack processing of the transmission means when the lower storage means is located at a position other than the lower end is unnecessary.

Further, since all the storage means can be raised and lowered via the pulley, the required torque and the required time for driving do not greatly differ between the rise and the fall. Also,
When the locking means is operated, the fourth pulley and the first pulley can be slightly lifted by the driving means, so that it is possible to release the load on the locking means from the accommodation means.

Still another lifting device according to the present invention includes a parking space, an upper housing means and a lower housing means which are vertically arranged in the parking space and which can move up and down, and which house the vehicle. A first fixed pulley and a second fixed pulley disposed in the upper part of the space, a first pulley disposed in the upper receiving means, a second pulley disposed in the lower receiving means, Flexible transmission means for moving up and down separately,
Driving means capable of moving the transmission means in its longitudinal direction;
At least a lock means for stopping and fixing the upper storage means at the ascending position and a lock means for stopping and fixing the lower storage means at the lowered position, the transmission means having one end fixed to the parking space. Then, at least the first fixed pulley is engaged from above, then at least the first pulley is engaged from below and suspended, and then at least the second fixed pulley is engaged from above. The other pulley is engaged with the second pulley from below and suspended, and the other end is fixed to the parking space.

Therefore, when the upper storage means is at the upper position in the parking space and the lower storage means is at the reference position at the lower position in the parking space, the lower storage means is fixed in the upper position by the locking means. By moving the transmission means so that the second pulley is lifted or lowered, the lower housing means can be raised and lowered.
Also, if the transmission means is moved from the reference position to lower or raise the first pulley in a state where the lower storage means is fixed to the lower level by the lock means, the upper storage means can be lowered and raised.

At this time, the transmission means on the side of the storage means to be lifted and lowered by the drive means does not slack, so that there is no time lag for starting the movement of the storage means. Since both accommodation means are raised and lowered via the pulleys, the required torque and the required time for driving do not greatly differ between ascending and descending.
When the lock means of the upper housing means is operated, the first pulley can be lifted slightly if the lower housing means is stopped and fixed by the lock means. It is possible to release the load on the storage means. In addition, the above operation can be achieved by the short transmission means.

Still another lifting device according to the present invention includes a parking space, an upper housing means and a lower housing means which are vertically arranged in the parking space and which can move up and down, for housing a vehicle; A first fixed pulley and a second fixed pulley disposed in the upper part of the space, a first pulley disposed in the upper receiving means, a second pulley disposed in the lower receiving means, Flexible transmission means for moving up and down separately,
Driving means capable of moving the transmission means in its longitudinal direction;
At least a lock means for stopping and fixing the upper storage means at the ascending position and a lock means for stopping and fixing the lower storage means at the lowered position, the transmission means having one end fixed to the parking space. Then, at least engage the first fixed pulley from above, then engage at least the second pulley from below and suspend it, then engage at least the second fixed pulley from above, and then at least The first pulley is engaged with the first pulley from below and suspended, and the other end is fixed to the parking space.

Therefore, when the upper storage means is at the upper position in the parking space and the lower storage means is at the reference position at the lower position in the parking space, the lower storage means is fixed to the upper storage by the lock means. By moving the transmission means so that the second pulley is lifted or lowered, the lower housing means can be raised and lowered.
Also, if the transmission means is moved from the reference position to lower or raise the first pulley in a state where the lower storage means is fixed to the lower level by the lock means, the upper storage means can be lowered and raised.

At this time, the transmission means on the side of the storage means to be lifted and lowered by the driving means does not slack, so that there is no time lag for starting the movement of the storage means. Since both accommodation means are raised and lowered via the pulleys, the required torque and the required time for driving do not greatly differ between ascending and descending.
When the lock means of the upper housing means is operated, the first pulley can be lifted slightly if the lower housing means is stopped and fixed by the lock means. It is possible to release the load on the storage means. In addition, the above operation can be achieved by the short transmission means.

In any one of the above-described lifting devices, the driving means rotationally drives the first fixed pulley, and the transmission means is moved in the longitudinal direction by rotation of the first fixed pulley. For those configured in
Since it is not necessary to separately provide a driving means on the moving path of the transmission means, the whole apparatus becomes simple.

The pulleys and the transmission means include:
Sprockets and chains can be selected.

It is a side view which shows the state raised.

The lifting device described below is similar to that of FIG.
This is a lifting device that can be applied to the first parking facility 51. Of course, as shown in FIG. 11, the number of rows of the pallet is not limited to three, but may be one or more.

The elevating device 1 shown in FIG. 1 is disposed in a pair at the back of the upper pallet 2 and the lower pallet 3 in the parking space S on the opposite side to the vehicle entrance E. Although the pallets 2 and 3 are shown in the form of a flat plate for easy understanding, the actual pallets are bent to form grooves or the like for guiding the wheels. First, the drive shaft 4 is disposed so as to correspond to an upper portion of the parking space S near the rear edge of the upper pallet 2 at the upper position. The drive sprocket 5 is located at each end of the drive shaft 4, that is, at a position corresponding to above both ends near the rear edge of the upper pallet 2.
Is attached. Further, a driving device 6 for rotating and driving the driving shaft 4 is provided. First sprockets 7 are arranged at both ends near the rear edge of the upper pallet 2, and second sprockets 8 are arranged at both ends near the rear edge of the lower pallet 3. The portion where the drive shaft is provided may be a wall or a beam of the parking space S.

A chain 9 as a transmission means is looped around these sprockets 5, 7, 8. That is, the chain 9 is mounted on a pallet 2 (which may be a wall surface or a beam) at one end of the parking space S at the upper position U in the parking space S, and then the floating engagement sprocket 1
0 from below and suspends it, then engages with the drive sprocket 5 from above, and then lower pallet 3
The lower pallet 3 is engaged with the second sprocket 8 from below.
And then the first sprocket 7 of the upper pallet 2
And the other end is attached near the lower end of the middle position M of the parking space S. Then, the drive sprocket 5 is rotated in the forward and reverse directions by the drive unit 6, and the chains 9 are moved in both longitudinal directions, whereby the pallets 2, 3 are raised and lowered.

FIG. 1 shows a state where the upper pallet 2 is at the upper position in the parking space S and the lower pallet 3 is at the lower position in the parking space S. In this state, for example, a middle pallet (not shown) in an adjacent row can traverse and reach an empty space (hereinafter, also referred to as a middle position) M between the upper pallet 2 and the lower pallet 3. Therefore, the state of the pallets 2 and 3 shown in FIG. 1 is also referred to as a traversing reference position.

The engaging sprocket 10 is configured to be able to engage with the upper pallet 2 above it by being lifted by the chain 9. The upper pallet 2 is also raised by further lifting the engagement sprocket 10 in the engaged state.

FIG. 2 shows the details of the engagement sprocket 10. 2A is a front view of the engagement sprocket 10, FIG. 2B is a cross-sectional view taken along line BB of FIG.
FIG. 2C is a front view showing a state in which the engaging sprocket 10 is engaged with the upper pallet 2, and FIG.
FIG. 2 (e) is a plan view of FIG. 2 (c).

A sprocket wheel 10a is rotatably supported on the shaft 11. This shaft 11 has a chain guide 1 covering the outer periphery of the lower half of the sprocket wheel 10a.
2 and a support plate 13 for supporting the shaft 11
Are attached so as to surround the chain guide 12 in the lateral direction. A roller chain is used as the chain 9. On the other hand, an engaging portion 14 is formed on a side edge of the upper pallet 2. That is, the engagement sprocket 1
In order to stably move the chain 9 up and down, a pair of guide holes 15a for guiding the movement of the chain 9 is formed, and a guide rod 15b for engaging with and guiding the chain 9 is formed on the inner peripheral edge of the guide hole 15a. It is fixed. Further, the shaft 11
The engagement plates 16 that can be engaged with both side portions of the sprocket wheel 10a are fixed. The engagement plate 16 is formed of a plate member bent in a U-shape, and has cutouts 16a at both end edges thereof with which the shaft 11 can be engaged.

As shown in FIG. 1, at the upper position U, an upper lock device 17 for disabling the upper pallet 2 located there is provided. The upper lock device 17 is configured to be swingably driven between an operation position where the stopper arm 17a is engaged with the lower surface of the upper pallet 2 and a non-operation position where the engagement is released.

In this embodiment, the upper locking device 17 is used.
Is also used as a fall prevention device for the upper pallet 2. Therefore, the upper lock device 17 is located slightly below the normal ascent stop position of the upper pallet 2 so that the upper pallet 2 will not fall even if the chain 9 is cut or the brake fails. 17a.

As shown in FIGS. 1 and 3, a balance chain 20 is provided on both sides of each of the upper pallet 2 and the lower pallet 3. When the pallets 2 and 3 are lifted and lowered, the balance chain 20 applies a lifting force to the rear portions of the pallets 2 and 3 even when the pallets 2 and 3 are lifted.
Is to move up and down while keeping it almost horizontal. A pair of front and rear balance sprockets 21, 2 are provided at the front and rear ends of both sides of each pallet 2, 3, respectively.
2 are provided. Then, on both sides of the upper pallet 2, one end of each of the balance chains 20 is fixed to the upper position U of the parking space S, then engages with the front balance sprocket 21 from below, and then attaches to the rear sprocket 22 from above. After engaging, the other end is at the middle position M
It is fixed to. On both sides of the lower pallet 3, the balance chain 20 has one end thereof at the middle position M of the parking space S.
, And then engages the front balance sprocket 21 from below, then engages the rear sprocket 22 from above, and the other end is fixed at the lower position L.

In any pallet 2, 3, when the first sprocket 7 or the second sprocket 8 is raised by lifting, the rear balance sprocket 22 is also lifted, so that the balance chain 2 is lifted.
The front balance sprocket 21 is lifted by the tension of 0, and as a result, the pallets 2 and 3 are raised while the horizontal state is maintained. When the pallets 2 and 3 are lowered, the pallets 2 and 3 are lowered while maintaining the horizontal state similarly.

The operation of the lifting device 1 will be described with reference to FIGS.
This will be described below with reference to FIG. FIG. 3 shows the rear balance sprocket 22 shifted forward from the actual position for easy understanding.

To lower the upper pallet 2 from the traversing reference position in FIG. 1 to the middle position as shown in FIG.
After swingably driving the stopper arm 17a of the upper locking device 17 from the working position to the non-working position, the drive sprocket 5
Is rotated counterclockwise in the drawing, the engaging sprocket 10 is lowered by its own weight and the own weight of the upper pallet 2, and as a result, the upper pallet 2 is lowered to the middle position, and the landing on the middle position At the same time, the driving machine 6 stops. During this time, the lower pallet 3 remains stationary at its lower end due to its own weight, and no large tension acts on the chain 9 on the lower pallet 3 side of the drive sprocket 5.

To return the upper pallet 2 from the middle position to the upper position U in FIG. 1, the drive sprocket 5 may be rotated clockwise from the state shown in FIG. Then, the engagement sprocket 10 moves up to the upper position U in a state of being engaged with the lower surface of the upper pallet 2. When the upper lock device 17 is operated, the load is not applied to the stopper arm 17a of the upper lock device 17 because the upper pallet 2 is located at the regular ascent stop position slightly above the upper pallet 2. Similarly, no load is applied when the stopper arm 17a is retracted to the non-operating position. Moreover, there is no slack in the chain 9 during the above operation. At the traverse reference position in FIG. 1, the chain 9 has no play and is effectively used.

Next, from the horizontal reference position in FIG.
In order to raise the lower pallet 3 to the middle position as shown in FIG.
The drive sprocket 5 may be rotated in the counterclockwise direction in FIG. As a result, first, the upper pallet 2 together with the engagement sprocket 10 starts to be lowered by its own weight, but the upper pallet 2 is received by the stopper arm 17a at the slightly lowered position. Therefore, since the lowering of the first sprocket 7 is also prevented, the portion of the chain 9 which is engaged with the second sprocket 8 is raised, and the lower pallet 3 is raised. Further, the engagement sprocket 10 is disengaged from the upper pallet 2 by its own weight, and sags the slack portion of the chain 9. As a result, the lower pallet 3 is raised to the middle position, and the driving machine 6 is stopped. Stopped by To return the lower pallet 3 from the middle position to the lower position L in FIG. 1, the drive sprocket 5 may be rotated clockwise from the state of FIG. Then, the engagement sprocket 10 is raised, and the lower pallet 3 descends to the lower position L together with the second sprocket 8 to land on the bottom V of the parking space S. Therefore, the lower pallet 3
Does not land on the bottom V of the parking space S, the chain 9 has a slack portion, but does not have a slack portion at the traverse reference position.

FIG. 4 shows another embodiment. The lifting device 23 is a second fixing device suspended in an upper position for engaging the chain 9 from above between the driving sprocket 5 and the engagement sprocket 10 in the lifting device 1 shown in FIGS. 1 and 3. The lifting device 1 differs from the lifting device 1 in that an additional upper fixed sprocket 24 that is a pulley is provided. As described above, in the present invention, it is possible to add a fixed sprocket to a position that does not affect the elevating function, if necessary, such as a change in the position of the chain around the elevating device 1 of FIG. By adding the fixed sprocket, the first sprocket 7 and the engaging sprocket 1 are further added.
0 can be easily avoided, and the degree of freedom in designing the size and layout of the driving sprocket 5 and the first sprocket 7 can be increased. FIG. 4A is a side view of a main part of the elevating device 23 at a traversing reference position.
FIG. 4 (b) is a side view schematically showing a state where the lifting device 23 lowers the upper pallet to the middle position.
(C) is a side view schematically showing a state where the lifting device 23 raises the lower pallet to the middle position. This lifting device is also provided with a balance chain (not shown) similar to that shown in FIG. The relationship between the rotation direction of the drive sprocket 5 for raising and lowering each of the pallets 2 and 3 and the elevation is, of course, the same as in FIGS. 1 and 3.

FIG. 5 shows another embodiment. This lifting device 31 is different from the lifting device 1 of FIGS.
The difference is that a fifth pulley 32 is attached to the upper pallet 2 without detaching in place of the engagement sprocket 10. The fifth pulley is a roller having no engagement teeth for engagement with the chain 9 unlike a sprocket. Other configurations are shown in FIGS. 1 and 3
Therefore, the same reference numerals are given and the description is omitted. FIG. 5A is a side view of a main part of the elevating device 31 at a traversing reference position, and FIG. 5B is a side view of the main part schematically showing a state where the elevating device 31 lowers the upper pallet to the middle position. FIG. 5C is a side view schematically showing a state where the lifting device 31 raises the lower pallet to the middle position.

As shown, the operation of the elevating device 31 is almost the same as that of the elevating device 1. That is, the relationship between the rotation direction of the drive sprocket 5 for raising and lowering each of the pallets 2 and 3 and the raising and lowering of the pallets 2 and 3 is the same as in FIGS. 1 and 3 and is not shown, but is the same as in FIG. A balance chain is provided. The difference between the operations is that the lower pallet 3 is pulled up from the traversing reference position in FIG. 5A to the traversing reference position (FIG. 5C), as shown in FIG. Is the state of the chain 9 when the lower pallet 3 is lowered to the lower position L from FIG. 5A. When the lower pallet 3 is above the lower position L, the fifth pulley 3
Since the chain 2 does not separate from the upper pallet 2, the chain 9 necessarily separates from the fifth pulley 32 by its own weight and hangs down. As described above, the weight of the engaging sprocket 10 is added to the hanging portion of the chain 9 in the lifting device 1 of FIGS. 1 and 3, whereas the lifting device 31 of FIG.
The difference is that only the own weight is added.

Accordingly, in the elevating device 31, there is no need to devise such a method that the engaging sprocket 10 as shown in FIG. Instead, it is necessary to devise a method for securely engaging the fifth pulley 32 again after the chain 9 is separated from the fifth pulley 32 as shown in FIG.

FIG. 6A is a front sectional view of the fifth pulley 32,
FIG. 6B is a sectional view taken along line VI-VI of FIG.
FIG. 7C is a sectional view taken along the line VIc-VIc in FIG.
A roller wheel 32a is rotatably supported by a shaft 33 attached to a side of the upper pallet 2. As shown in FIGS. 6B and 6C, a groove 34 for engaging the chain 9 is formed along the outer periphery of the roller wheel 32a. A guide flange 35 for preventing the coming off is formed. A pair of guide holes 36 for guiding the movement of the chain 9 are formed in the upper surface of the side of the upper pallet 2. A guide rod 37 for preventing the chain 9 from coming off in the radial direction of the roller wheel 32a and for guiding the movement of the chain 9 is fixed to the inner peripheral edge of the guide hole 36. The guide rod 37 linearly extends vertically downward from the guide hole 36 to at least the horizontal diameter portion of the roller wheel 32a. As shown in FIG. 6C, the dimension D between the guide flange 35 and the guide bar 37 is narrow so that the chain 9 cannot pass. Also, the upper and lower ends of the guide rod 37 are slightly curved outward in order to avoid catching on the chain 9. Reference numeral 38 denotes a bearing.

With this configuration, in FIG. 5, when the lower pallet 3 is raised, the chain 9 can be disengaged downward from the fifth pulley 32 without any obstacle. When the lower pallet 3 has landed on the lower position, the chain 9
Can re-engage the fifth pulley 32 without the engagement teeth without any obstacle.

When the lower pallet 3 is located at a position other than the lower end, a part of the chain 9 hangs down from the fifth pulley 32. However, since this is not the portion on the lower pallet 3 side to be raised and lowered, the pallets 2, 3 There is no time lag at the start of movement. When the upper pallet 2 is moved up and down, the chain 9 does not sag. Further, the upper pallet 2 can be slightly lifted by driving the chain 9, so that the upper pallet lock device 17 is not operated with a load applied.

FIG. 7 shows another embodiment. This elevating device 41 differs from the elevating device 23 of FIG. 4 in that the fifth pulley 32 shown in FIG. 6 is attached to the upper pallet 2 without being detached, instead of the engagement sprocket 10. Other configurations are the same as those of the lifting device 23 of FIG.
FIG. 7A is a side view of a main part of the lifting / lowering device 41 at a traversing reference position, and FIG. 7B is a side view of a main part schematically showing a state where the lifting / lowering device 41 has lowered the upper pallet to the middle position. FIG. 7C is a side view schematically showing a state where the lifting device 41 raises the lower pallet to the middle position.

In the lifting device 41, similarly to the lifting device 31 shown in FIG. 5, when the lower pallet 3 is located above the lower position L, the fifth pulley 32 does not separate from the upper pallet 2, so that the chain 9 is inevitably. Is separated from the fifth pulley 32 by its own weight and hangs down. Then, similarly to the above-described lifting device, there is no time lag at the start of the movement of the pallets 2 and 3, and the upper locking device 17 is not operated with a load applied.

FIG. 8 shows still another embodiment. The lifting device 25 has an additional third sprocket 26 serving as a third pulley on both sides of the lower pallet 3 in the lifting device 1 shown in FIGS. 1 and 3. Further, on both sides of the upper pallet 2, fourth sprockets 18, which are fourth pulleys which are always integrated with the upper pallet 2, are disposed in place of the engagement sprockets 10 described above. Also,
At the upper position U, two additional upper fixed sprockets 24 (which may be one or three or more) as a second fixed pulley are suspended, and at the lower position L, an additional upper fixed sprocket 24 which is a third fixed pulley. The lower fixed sprocket 27 is protruded upward (two or even three or more) upward.

The difference between the lifting and lowering device 25 and the lifting and lowering device 1 shown in FIG.
After being engaged from below, is not immediately fixed to the upper position U, engages the two upper fixed sprockets 24 from above, then engages the two lower fixed sprockets 27 from below, and then engages the lower After engaging with the third sprocket 26 of the pallet 3 from above, the other end is fixed at the lower position L. The relationship between the rotation direction of the drive sprocket 5 for raising and lowering each of the pallets 2 and 3 and the vertical movement is the same as in FIGS. 1 and 3. However, the slack portion of the chain 9 that is about to be generated on the upper pallet 2 side from the drive sprocket 5 by the raising and lowering drive of the lower pallet 3 is integrated with the lower pallet 3 via the upper fixed sprocket 24 and the lower fixed sprocket 27. Sprocket 26
As a result, the chain 9 does not sag. Therefore, in this embodiment, the chain 9 does not sag during the process of lifting and lowering all the pallets. In addition, since the upper pallet 2 can be slightly lifted by driving the chain 9, the upper pallet 2 does not operate with a load applied thereto.

FIG. 8A is a side view of a main part of the lifting device 25 at the traverse reference position, and FIG. 8B schematically shows a state in which the lifting device 25 lowers the upper pallet to the middle position. FIG. 8C is a side view schematically showing a state where the lifting device 25 raises the lower pallet to the middle position. This lifting device is also provided with a balance chain (not shown) similar to that shown in FIG.

In all of the above-described lifting devices 1, 23, and 25, the drive of the chain 9 is the drive sprocket 5, but the present invention does not particularly limit the drive of the chain to the drive sprocket 5.

FIG. 9 shows another lifting device 28. In this lifting / lowering device 28, the driving sprocket 5 and one upper fixed sprocket 24 (or two or more) may be provided at the upper position U, the first sprocket 7 may be provided on the upper pallet 2, and the lower pallet 3 may be provided on the lower pallet 3. A second sprocket 8 is provided. The chain 9 has one end fixed to the upper position U, then engages with the driving sprocket 5 from above, then engages with the first sprocket 7 of the upper pallet 2 from below and suspends it, and then It engages with the fixed sprocket 24 from above, then engages with the second sprocket 8 of the lower pallet 3 from below, suspends it, and fixes the other end to the middle position M. Although not shown, a balance chain similar to that shown in FIG.

At the lower position L of the elevating device 28, a lower lock device (not shown) for disabling the lower pallet 3 located there is provided. The lower lock device is, for example, an upper lock device 17 shown in FIG.
The upper and lower pallets 2 are completely inverted. The stopper arm is configured to swing between an operation position where the stopper arm is engaged with the upper surface of the lower pallet 3 from above and a non-operation position where the engagement is released.

It is preferable that the upper lock device (not shown) of the present embodiment also has a function of disabling the upper pallet 2 from being further raised at the normal lifting stop position. However, a simple fixed contact member may be provided at an appropriate position of the upper position U to prevent the upper pallet 2 from rising above the lifting stop position.

FIG. 9A is a side view of a main part of the lifting device 28 at the traversing reference position, and FIG. 9B is a schematic diagram showing a state in which the lifting device 28 lowers the upper pallet 2 to the middle position M. 9 (c) is a side view schematically showing a state in which the elevating device 28 raises the lower pallet 3 to the middle position M.

In order to lower the upper pallet 2 at the traversing reference position (FIG. 9A)
The drive sprocket 5 may be rotated counterclockwise in the drawing while the lower pallet 3 is fixed by a lower lock device (not shown). To return to the traverse reference position, the drive sprocket 5 is rotated clockwise. In order to raise the lower pallet 3 to the middle position, the upper pallet 2
It is sufficient to rotate the driving sprocket 5 clockwise in the drawing while fixing the position, and to return it to the traverse reference position, rotate it counterclockwise. When the pallets 2 and 3 are lifted, the chain 9 between the driving sprocket 5 and the upper fixed end slacks (indicated by the symbol H in FIG. 9), but between the driving sprocket 5 and the pallets 2 and 3 to be lifted and lowered. The portion of the chain 9 does not slack, so that a time lag does not occur when the drive sprocket 5 starts moving up and down. In addition, if the lower pallet 3 is kept stationary and fixed by the lower lock device, the upper pallet 2 can be slightly lifted, so that the upper pallet device 17 is not operated with a load applied. The above-mentioned normal lifting stop position includes this slight lifting dimension. Also, it is possible to add a fixed sprocket to the lifting device 28 within a range where the lifting function does not change.

FIG. 10 shows another lifting device 29. FIG. 10A is a side view of a main part of the elevating device 29 at the traversing reference position, and FIG. 10B is a schematic diagram showing a state in which the elevating device 29 lowers the upper pallet 2 to the middle position M. FIG. 10C is a side view schematically showing a state where the lifting device 29 raises the lower pallet 3 to the middle position M.

This elevating device 29 is different from the elevating device 28 of FIG. 9 in that the arrangement of the first sprocket 7 and the second sprocket 8 on both sides of the upper fixed sprocket 24 is reversed as shown in the figure. It is. That is, in the elevating device 29 shown in FIG. 10, the chain 9 that has been engaged with the drive sprocket 5 and hung down first engages the second sprocket 8 from below, and then engages the upper fixed sprocket 24 from above. The first sprocket 7 is engaged from below. In this elevating device 29 as well, the chain 9 between the driving sprocket 5 and the upper fixed end slacks (indicated by the symbol H in FIG. 10), but the chain 9 between the driving sprocket 5 and the pallets 2 and 3 to be raised and lowered. Since the portion of the chain 9 does not slack, no time lag occurs when the drive sprocket 5 starts moving up and down. In addition, if the lower pallet 3 is kept stationary and fixed by the lower lock device, the upper pallet 2 can be slightly lifted, so that the upper pallet device 17 is not operated with a load applied. Further, it is possible to add a fixed sprocket to the elevating device 29 as long as the elevating function does not change.

Each of the lifting and lowering devices 28 shown in FIGS.
Although the drive sprocket 5 drives the chain 9 in 29, the chain drive is not particularly limited to the drive sprocket 5 in the present invention.
