Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a pallet transfer device for an elevator parking system.

(Prior Art) Generally, an elevator parking device includes a lifting platform that supports and lowers a pallet on which a vehicle is placed, and a large number of parking shelves on both sides of a hoistway of the platform to accommodate the vehicle and the pallet. are arranged in layers (in multiple stages) along the hoistway of the elevating platform, and the elevating platform and each parking shelf are connected to allow pallets to be transferred between the two.

As a pallet transfer device for such an elevator parking device, a fork for supporting the pallet is provided on the lifting platform, and the fork is moved between the elevator platform and the parking shelf, and is moved up and down on the parking shelf. A system is known in which a pallet is transferred between a lifting platform and a parking shelf by movement (see Japanese Patent Application Laid-Open No. 62-284864).

In addition, a chain suspended from a pair of sprockets is provided on the lifting platform, an engaging member for engaging the pallet is attached to the chain, and the engaging member is run by the chain to transfer the pallet between the lifting platform and the parking section. There are also known devices that do this (see, for example, Japanese Utility Model Publication No. 51-28786).

(Problem to be Solved by the Invention) However, in the case of the above-mentioned pallet transfer device using forks, the fork must be inserted under the pallet in the parking shelf and the pallet must be able to move up and down with the vehicle mounted on the pallet. , it is necessary to widen the space between the upper and lower parking shelves. Furthermore, since the fork must be moved up and down and the distance required to transfer the pallet to the parking shelf and then return the fork to the lifting platform is long, it takes time to transfer the pallet.

On the other hand, in the case of a pallet transfer device using a chain, it is not necessary to move the pallet up and down, but the engaging member can be extended from the hoistway toward the parking shelf side in order to engage with the pallet on the parking shelf. This makes it difficult to avoid interference between the engaging member and the pallet of the parking shelf when raising and lowering the elevator platform.

In other words, an object of the present invention is to solve the problem without increasing the vertical distance between the parking shelves and without causing any hindrance to the raising and lowering of the elevator platform.
The purpose is to allow pallets to be transferred quickly.

(Means for Solving the Problems) In order to solve such problems, the present invention provides a pallet support member on the lifting platform so as to be movable in the pallet transfer direction, and engages the pallet with the pallet support member and supports the pallet. An engaging member is provided that is movable relative to the pallet support member so as to move the pallet.

Specifically, the specific means for this purpose includes a lifting platform that supports a pallet on which a vehicle is placed and moves up and down, and a plurality of parking shelves arranged in layers along the hoistway of this lifting platform and each accommodating a vehicle together with the pallet. A pallet transfer device for an elevator parking system, which connects the lifting platform and each parking shelf to transfer pallets between the two, and is movable in the pallet transfer direction onto the lifting platform. a pallet support member that is provided on the pallet support member and has a running path for supporting the pallet while being movable in the transfer direction; and a pallet support member that is provided on the pallet support member so as to be relatively movable in the pallet transfer direction and that is detachable from the pallet. an engaging member; an engaging member moving means that engages the engaging member with the pallet and moves the pallet in a pallet transport direction so that the pallet travels; and the engaging member engages the pallet supporting member with the pallet of the parking shelf. The present invention is characterized by comprising a support member moving means for moving the support member toward the parking shelf side so as to move the support member to the parking shelf side (hereinafter, this will be referred to as the first means).

In the first means, the parking shelves can be arranged in layers on both sides of the hoistway along the hoistway, and in that case, engagement pieces projecting downward are provided at both ends of the pallet in the transport direction. A sprocket is supported at each end of the pallet supporting member in the pallet transfer direction, an endless conveyor chain is suspended around the sprocket, and an engaging member is attached to the conveyor chain. movable relative to the pallet support member, and engages with the engagement piece of the pallet when the conveyor chain moves from the return side to the carrier side, and disengages from the engagement piece when the conveyor chain moves from the carrier side to the return side. The engaging member moving means can be constituted by a drive motor that causes the conveyor chain to travel in forward and reverse directions (hereinafter referred to as the second means).

In addition, in the first means, a transition rail is provided at the end of the pallet support member on the parking shelf side, which is perpendicular to the pallet transport direction, and extends between the travel path of the pallet support member and the parking shelf to allow the pallet to travel. The pallet support member is supported so as to be vertically swingable by a horizontal support shaft, and the tip of the crossing rail and the parking shelf are engaged with each other by moving the pallet support member toward the parking shelf, and the pallet rail is allowed to swing vertically. (hereinafter, this will be referred to as jfi3 means).

(Function) In the above first means, the pallet is transferred from the lifting platform to the parking shelf by moving the pallet support member to the parking shelf so that the engaging member can be engaged with the pallet when it is on the parking shelf by the support member moving means. Do this with it pulled to the side. That is, by engaging the engaging member with the pallet of the pallet support member and moving it toward the parking shelf by the engaging member moving means, the pallet is caused to run on the travel path of the pallet support member and sent to the parking shelf. .

In this case, since the pallet support member is moved toward the parking shelf as described above, the engaging member can completely feed the pallet to the parking shelf. Then, the pallet support member can be moved toward the parking shelf to a position where the engaging member of the pallet traveling means can be engaged with the pallet on the parking shelf.
After the pallet is transferred to the parking shelf, the distance traveled to return the pallet support member to the elevator platform is short. Of course, there is no need to move the pallet support member up and down when placing the pallet on the parking shelf.

Furthermore, when transferring a pallet from a parking shelf to an elevator platform, the pallet support member is moved toward the parking shelf side as described above, thereby causing the engaging member to engage with the pallet on the parking shelf, and vice versa. By moving the pallet in the direction, the pallet can be transferred from the parking shelf onto the lifting platform.

As described above, since the pallet support member is movable on the elevator platform, when the elevator platform is raised or lowered, the pallet support member is retracted from the parking shelf side onto the elevator platform. Alternatively, the engaging member can be prevented from interfering with the parking shelf side.

In the second method, when there is a pallet on the lifting platform, by running the conveyor chain in either forward or reverse direction, the engaging member is sent from the return side to the carrier side at one end of the conveyor chain, and the pallet is palletized. The pallet can be engaged with the engaging piece at one end, sent to the parking shelf in front of the other end, and disengaged from the engaging piece at the other end of the conveyor chain, and the conveyor chain can be moved in the other direction. When running, the engaging member is sent from the return side to the carrier side at the other end of the conveyor chain to engage the engaging piece at the other end of the pallet, and this pallet can be sent to the parking shelf in front of one end. . In either case, the pallet support member is moved toward the parking shelf to which the pallet is to be transferred.

Also, when transferring a pallet from a parking shelf to a lifting platform, the pallet support member is moved toward the parking area, and the conveyor chain is run in either the forward or reverse direction to move the engaging member to the parking shelf. By sending the pallet from the return side to the carrier side at the end of the side, the pallet of the parking shelf is engaged with the engagement piece located near the hoistway, and the pallet can be transferred onto the elevator platform.

In the third means, when the pallet support member is moved toward the parking shelf, the engaging portion at the tip of the crossing rail provided at the end of the pallet supporting member engages with the engaging portion of the parking shelf, and the connecting rail will form a communication path for transferring pallets between the pallet support member and the parking shelf. and,
This crossover rail is supported by the pallet support member so as to be able to swing up and down, and is engaged with the parking shelf to allow this vertical swing, so there is no vertical misalignment between the pallet support member and the parking shelf. If this occurs, the crossing rail will tilt according to the positional shift.

In other words, when a vehicle is transferred from the pallet support member of the platform to the parking shelf, the load acting on the platform decreases as the vehicle moves toward the parking shelf, and vice versa. When doing so, the load acting on the lifting platform increases. However, in the case of the above-mentioned method in which the lifting platform is suspended by wire lobes and raised and lowered, the wire lobes normally expand and contract slightly depending on the tensile force they receive. The platform expands and contracts slightly, and the height of the pallet support member of the elevator rises and falls accordingly, creating a step between it and the parking shelf.

At this time, the transition rail is tilted to maintain communication between the pallet support member and the parking shelf, and the transition rail does not come off from the parking shelf or is damaged.

In addition, the height discrepancy between the pallet and the parking shelf may be caused by changes in the load after the lifting platform has stopped, such as the expansion and contraction of the wire lobes, or due to an error in the stopping position of the lifting platform itself in the hoistway. In that case, by providing a guide means between the engaging part of the crossing rail and the engaging part of the parking shelf to guide the mutual engagement, it is possible to set the crossing rail in an inclined state and move the pallet. It is possible to communicate between the support member and the parking area.

(Effect of the invention) According to the first means, a pallet support member movable in the pallet transfer direction is provided on the lifting platform, and by moving this pallet support member toward the parking shelf side, Since the engaging member can be engaged with the pallet on the parking shelf, it is possible to bring the pallet supporting member closer to the parking shelf and shorten the return distance of the pallet supporting member after the pallet is transferred from the lifting platform to the parking shelf. In addition, there is no need to move the pallet support member up and down when placing a pallet on the parking shelf, and the lifting platform can be raised and lowered without interfering with the parking shelf, which ultimately reduces the vertical spacing of the parking shelf. Pallets can be quickly transferred without increasing the space and without hindering the lifting and lowering of the lifting platform.

According to the second means, in which parking shelves are arranged on both sides of the hoistway, engaging pieces are provided at both ends of the pallet, and the engaging members are engaged with the engaging pieces of the pallet by the running of the conveyor chain. Since the pallet can be removed, the pallet can be smoothly transferred between the lifting platform and any of the parking shelves on both sides of the hoistway by running the conveyor chain in the forward and reverse directions.

According to the third means, the rail across the end of the pallet support member on the parking shelf side is supported so as to be able to swing up and down by a horizontal support shaft perpendicular to the pallet transport direction, and the tip of the crossing rail and the parking shelf are supported in a vertically swingable manner. Since an engaging portion is provided between the pallet support member and the parking shelf so that the pallet support member engages with each other when the pallet support member moves toward the parking shelf and allows vertical swinging of the crossing rail, a step is created between the pallet support member and the parking shelf. However, it is possible to connect the pallet support member and the parking shelf with the transition rail tilted, and when transferring the pallet, the above-mentioned steps can cause sudden vertical movement of the pallet, impact, and even collisions. The pallet can be smoothly transferred between the pallet support member and the parking shelf without causing any problems.

2 and the engagement bin 63,
The engagement pin 63 is reliably fitted into the engagement recess 62 by being guided by the guide surface 62a of the engagement recess 62.

In this case, the crossing rail 42 rotates around the horizontal support shaft 61 of the running rail 37 so that its tip is at a high position or at a low position, but this rotation is caused by the engagement with the engagement pin 63 of the shelf rail 9a. The mating recess 62 functions as a hinge and is allowed, and the crossing rail 42 and the like will not be damaged.

(3) Transfer of pallet The pallet 12 is transferred to the parking shelf 9 side by the pallet moving means 32. That is, when the pallet 12 is on the pallet member 31, the engaging pins, for example 45a, 45c, are inserted into the engaging recesses 18a, 18g of the engaging pieces 18.18 on both sides.
are in an engaged state at the same time.

Therefore, when the target parking shelf 9 is the one on the right side in FIG. 4, the conveyor chain 47 is rotated clockwise by the operation of the drive motor 23, so that the engagement pin 45a at the left end in the figure is attached to the parking shelf 9 on the right side. Move it to the side. As a result, the wheels 17 of the pallet 12 are transferred from the top of the running rail 37 of the pallet support member 31 to the shelf rail 9a of the parking shelf 9 on the right side via the crossing rail 42, so that the pallet 12 is moved to the right side. It is transferred to the parking shelf 9. Then, after the engagement pin 45a is removed from the engagement recess 18a by turning from the carrier side to the return side of the conveyor chain 47, the engagement piece 18 is pushed back by the following engagement pin 45b to further push the pallet 12. Move the pallet to the parking shelf 9
It can be completely transferred to

The pallet 12 rides on the inclined transfer surface 81a of the outer stopper 81 of the shelf rail 9a at the end of the transfer by the pallet transfer means 32, thereby avoiding a sudden stop and stopping at a predetermined position without causing a large impact. do.

By the way, when the vehicle W is placed on the pallet 12, the load acting on the elevator platform 7 decreases as the vehicle W moves toward the parking shelf 9 side. As a result, the wire rope 13 suspending the lifting platform 7 is slightly shrunk, and the height of the pallet support member 31 of the lifting platform 7 is increased. At that time, the crossing rail 42 rotates around the horizontal support shaft 61 of the traveling rail 37 so that its tip is in a low position, but since this rotation is allowed as described above, the crossing rail 42, etc. No damage will occur.

■ Returning the pallet support member, then moving the pallet support member 31 to the support member moving means 33.
It is returned to the top of the lifting platform 7 (center position) by the operation of . As a result, the stopper 71 at the end of the running rail 37 and the inner stopper 82 of the shelf rail 9a return to their stopper positions. In this case, since the return distance of the pallet support member 31 is short, the lifting platform 7 can quickly move on to the next loading/unloading operation.

In addition, when the parking shelf 9 to which the pallet 12 is to be transferred is on the left side, the pallet support member 31 may be moved toward the left parking shelf 9 side and the conveyor chain 47 may be rotated clockwise.

Therefore, as described above, when the pallet support member 31 is returned to the top of the lifting platform 7, the pallet traveling means 32 does not interfere with the parking shelf 9, so there is no problem in raising and lowering the lifting platform 7.

Transferring the Pallet from the Parking Shelf to the Elevating Platform> With the elevating platform 7 stopped at the desired parking shelf 9 position, the pallet support member 31 is moved toward the parking shelf 9 side by the support member moving means 33. The operations of the crossing rail 42 and stoppers 71 and 82 at this time are the same as in the case of transferring the pallet 12 from the lifting platform 7 to the parking shelf 9 described above.

If the desired parking shelf 9 is the one on the right side in FIG.
Pallet 1 is sent from the return side of 7 to the carrier side.
Engagement recess 18a of engagement piece 18 located on the hoistway 8 side of No. 2
, and the pallet 12 is transferred from the shelf rail 9a through the crossover rail 42 onto the traveling rail 37. Then, the pallet support member 31 is returned to its original position by the support member moving means 33.

In addition, when the target parking shelf 9 is the one on the left side, the pallet support member 31 may be moved toward this left parking shelf 9 side, and the conveyor chain 47 may be rotated clockwise.

Regarding Pallet Travelability> If a height difference occurs between the pallet support member 31 of the lifting platform 7 and the parking shelf 9, the horizontal rail surface 42a of the crossing rail 42 will be tilted due to the rotation of the crossing rail 42. This prevents the occurrence of a sudden level difference between the running rail 37 and the shelf rail 9a, and does not impede the running of the pallet 12.

Therefore, when the horizontal rail surface 42a of the crossover rail 42 slopes upward toward the shelf rail 9a, the pallet support height at the base end of the horizontal rail surface 42a is Since the height is the same, there is no difference in level between the running rail 37 and the crossing rail 42, only the angle of the rail surface is changed. Also, between the transition rail 42 and the shelf rail 9a, the inclined rail surface 42c at the tip of the transition rail 42 connects the horizontal rail surface 42a and the shelf rail 9a, so that no step occurs.

On the other hand, when the horizontal rail surface 42a of the crossover rail 42 slopes downward toward the shelf rail 9a, the arcuate rail surface 42b at the base end of the horizontal rail surface 42a is formed in an arc shape concentric with the horizontal support shaft 61. Since this crossing rail 4
There is no difference in level between 2 and the traveling rail 37. Also, no level difference occurs between the transition rail 42 and the shelf rail 9a, as long as the horizontal rail surface 42a of the transition rail 42 is connected to the shelf rail 9a in an inclined state.

After all, there is no difference in level between the running rail 37 and the shelf rail surface 9a even if the transition rail 42 is rotated up and down, so the pallet 12 can be moved between the running rail 37 and the shelf rail. This means that you can travel smoothly between 9a and 9a.
