[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a measure for efficiently transferring a vehicle between a transport means and a storage shelf in a mechanical parking apparatus in which a plurality of storage shelves are provided in front and rear of a transport path.
[0002]
[Prior art]
For example, as disclosed in JP-A-11-241520 and JP-A-11-247485 as a mechanical parking device in which two storage shelves are arranged on the front and rear of a conveyance path like a double shelf. In addition to mounting the swivel arm type lateral feed device on the transport carriage as the transport means and mounting the chain carrier type lateral feed device on the storage shelf in the back, it is possible to move forward and backward by the linkage operation of the above two types of lateral feed devices. 2. Description of the Related Art A plane reciprocating parking apparatus is known that efficiently transfers a vehicle between two storage shelves and a transport carriage.
[0003]
[Problems to be solved by the invention]
However, in the above-described plane reciprocating parking apparatus, since different types of lateral feeding devices having completely different lateral feeding mechanisms are adopted for the transport carriage and the rear storage shelf, the equipment cost increases.
[0004]
In other words, the swivel arm type lateral feed device of the transport carriage is such that the engaging roller at the tip of the crank arm is engaged with the guide groove on the back surface of the pallet and the empty pallet or the in-vehicle pallet is laterally fed by the turning motion of the crank arm. is there. On the other hand, the chain carrier type lateral feed device for the rear storage shelf is configured such that the endless chain is wound around a pair of sprockets, and the engaging member attached to the endless chain is engaged with the engaged member attached to the pallet. The empty pallet or the in-vehicle pallet is laterally fed by chain driving. As described above, the both lateral feed devices have completely different lateral feed mechanisms.
[0005]
Naturally, two different types of engaged means (guide grooves, engaged members) must be provided on the pallet side corresponding to two types of horizontal feeding devices having different horizontal feeding mechanisms, and the structure of the pallet is complicated. It will lead to a rise in costs.
[0006]
Further, since the lateral feed device of the transport carriage is of a swing arm type, in order to laterally feed the pallet, the crank arm must be swung and the engagement roller at the tip must be engaged with the guide groove on the back of the pallet. During this time, the pallet cannot be laterally fed, which is a loss time from the viewpoint of improving the loading / unloading efficiency.
[0007]
The present invention has been made in view of the above points, and the object of the present invention is to reduce the facility cost and to promptly enter / exit.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is characterized in that both the lateral feeding device of the conveying means and the lateral feeding device of the storage shelf are unified into a chain carrier type.
[0009]
Specifically, in the present invention, a plurality of storage shelves are provided in front of and behind the transport path, and the vehicle is laterally fed and transferred between the transport means moving on the transport path and the storage shelves. The following solutions were taken for mechanical parking devices that were designed to store and remove vehicles.
[0010]
That is, the invention according to claim 1 is provided with guide rollers for pallet delivery arranged in two places on the left and right sides when viewed from the transport path side of the storage shelf and two places in the front and rear of the transport means in the moving direction. Only one location that is close to the inside of the guide roller that supports the side where the front and rear weight of the vehicle mounted on the pallet is larger in the storage shelf excluding the front storage shelf on the transport path side among the storage shelves in the front and rear in the moving direction. Both include a chain carrier type lateral feed device including a pair of sprockets and an endless chain that is wound around the sprockets and has an engaging member that engages with the pallet and laterally feeds the pallet. It is characterized by that.
[0011]
With the above configuration, the invention according to claim 1 employs the same type of lateral feed mechanism for the conveying means and the rear storage shelf, so only one type of lateral feed device may be used, and the structure of the pallet. The equipment cost can be greatly reduced compared to the case of adopting different types of horizontal feeding devices. Further, since the lateral feed device is a chain carrier type, the pallet can be laterally fed immediately at the same time as the endless chain is driven, and there is no loss time as in the case of the swivel arm type lateral feed device. In addition, the lateral feed device is provided only at one position that is close to the inside of the guide roller that supports the side where the front and rear weight of the vehicle mounted on the pallet is large in the storage shelf excluding the front storage shelf on the conveyance path side. The pallet is difficult to bend even if the weight of the vehicle is applied, so that the pallet is not bent. There is no need to secure the ceiling height, and the storage portion can be set shallower by that amount. In addition, the cost can be halved compared to the case where the transverse feeding device is provided on both sides. Furthermore, since the transverse feeder is installed only on the side front and rear heavy weight vehicles, be provided with a transverse feeder on only one side, the generation of a force to incline the vehicle pallet obliquely in plan view as much as possible suppressed, smooth Can be moved straight.
[0012]

Is characterized in that the lateral feed drive is performed independently of the other lateral feed device.
[0013]
With the above configuration, in the invention according to claim 2, even if the transport means is not waiting on the side of the storage shelf, the storage shelf's lateral feed device enables the pallet to be laterally fed by the front and rear storage shelves, The next loading / unloading operation is ready and the loading / unloading efficiency is improved.
[0014]
According to a third aspect of the present invention, in the first aspect of the invention, the transverse feeding device for the storage shelf includes an overshoot prevention member provided in the vicinity of the engaging member, and the rear storage of the front storage shelf is provided. When the pallet is not stored on the shelf, the pallet movement is restricted by the above-mentioned overshoot prevention member so that the pallet paid out from the transport means does not exceed the storage area of the front storage shelf. .

[0018]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0019]
FIG. 3 shows a plane reciprocating parking apparatus as a mechanical parking apparatus according to an embodiment of the present invention. This plane reciprocating parking apparatus mounts a vehicle C on a pallet P (appears in FIGS. 1 and 2). It is a type to enter and exit.
[0020]
In FIG. 3, 1 is a storage unit provided in the basement, and this storage unit 1 is communicated with a loading / unloading port (not shown) of a loading / unloading unit provided on the ground by a loading / unloading lift 2. ing. One carriage traveling path 3 serving as a conveyance path is provided substantially at the center of the storage unit 1, and the carry-in / out lift 2 is juxtaposed with the carriage traveling path 3.
[0021]
A plurality of storage shelves 4 a and 4 b for storing the vehicle C together with the pallet P are arranged on both sides of the bogie travel path 3 along the bogie travel path 3 in two front and rear rows. Two traveling rails 5 are laid on the floor surface of the carriage traveling path 3, and a transportation carriage 6 is disposed on the two traveling rails 5 as a conveying means for carrying and conveying the vehicle C together with the pallet P. Has been.
[0022]
As shown in FIG. 1, the transport cart 6 includes a cart body 7 formed of a rectangular frame, and four wheels 8 are provided at both ends of two front and rear axles 9 at four corners of the cart body 7. The wheels 8 are mounted one by one so as to be rotatable, and these wheels 8 are mounted on the travel rail 5 so as to be able to roll by the activation of a travel motor (not shown).
[0023]
Five guide rollers 10 for delivering the pallet P are lined up and supported by guide frames (not shown) at two locations in the front and rear of the carriage body 7 in the moving direction. The feeding device 11 is supported and mounted on a support frame (not shown). The first lateral feed device 11 includes a pair of sprockets 12 provided at both ends in the width direction of the carriage main body 7 and two endless chains 13 wound around the sprocket 12, and the two endless chains. The lower middle part 13 is wound around two idlers 14 and interlocking sprockets 15. The two interlocking sprockets 15 of the pair of front and rear first lateral feed devices 11 are connected by a shaft 16, and this shaft 16 is connected to a first geared motor 17 as a drive source by a drive sprocket 18 and a driven sprocket 19. When the first geared motor 17 is activated, the pair of front and rear first lateral feed devices 11 are synchronously chain driven.
[0024]
Further, an engagement pin (not shown) as an engagement member is attached between the two endless chains 13 of each first lateral feed device 11. Since this engagement pin is the same as the engagement pin 26 (see FIG. 2) of the second lateral feed device 20 described later, the same reference numeral is used in the following description. The engaging pins 26 are engaged with grooves p2 of engaged pieces p1 as engaged members provided at the four corners of the pallet P so that the pallet P is placed between the front storage shelf 4a and the transport carriage 6. Alternatively, it is transferred laterally between the loading / unloading lift 2 and the transport carriage 6 for delivery.
[0025]
On the other hand, on the left and right sides of the front storage shelf 4a and the back storage shelf 4b as viewed from the cart traveling path 3 side, five guide rollers 10 for delivering the pallet P are respectively supported by guide frames (not shown) and arranged in rows. Of the storage shelves 4a and 4b, the chain carrier type second lateral is also provided only at one position close to the inside of one guide roller 10 of the back storage shelf 4b excluding the front storage shelf 4a on the cart traveling path 3 side. The feeding device 20 is supported by a support frame (not shown) and is installed close to it. The second lateral feed device 20 is installed on the side where the front and rear weights of the majority of vehicles C mounted on the pallet P are large, such as the engine side or the storage battery side. In this way, the second lateral feed device 20 is installed only on the side where the majority of the vehicles C are heavy in the front-rear weight, even if the second lateral feed device 20 is provided only on one side, the in-vehicle pallet P can be viewed in plan view. This is to suppress the generation of a force to incline obliquely as much as possible and to move it smoothly and straight. Even if the second lateral feed device 20 is provided only on one side in this way, the second lateral feed device 20 is not required to have as much positional accuracy as the first lateral feed device 11 of the transport carriage 6 and will be described later. In addition, since the lateral feed speed is set slower than that of the first lateral feed device 11, no practical problem occurs. On the other hand, the first lateral feed device 11 is mounted on the transport cart 6 at two positions in the front and rear, because the transport cart 6 is a moving body, and if the position shifts, the delivery is hindered or the support state is unstable. Because it is dangerous.
[0026]
As shown in FIG. 2, the second lateral feed device 20 includes a pair of sprockets 21 provided on a support frame (not shown) and two endless chains 22 wound around the sprocket 21. The lower back end of the two endless chains 22 is wound around an idler 23 and a tension sprocket 24. In FIG. 1, the idler 23 and the tension sprocket 24 are omitted. The sprocket 21 at the far end of the pair of sprockets 21 is drivingly connected to a second geared motor 25 (appearing in FIG. 1) as a driving source, and the second lateral feed device 20 is activated by the activation of the second geared motor 25. It is designed to drive a chain.
[0027]
An engagement pin 26 as an engagement member is attached between the two endless chains 22. The engaging pins 26 engage with the grooves p2 of the engaged pieces p1 provided as the engaged members provided at the four corners of the pallet P, thereby bringing the pallet P into the front storage shelf 4a and the back storage shelf 4b. It is designed to be handed over between them. That is, the first lateral feed device 11 of the transport carriage 6 and the second lateral feed device 20 of the back storage shelf 4b are provided with the first geared motor 17 and the second geared motor 25, respectively, independent of each other. The lateral feed device 11 (or 20) is laterally driven independently of the other lateral feed device 20 (or 11) by activation of the first geared motor 17 (or 25).
[0028]
Further, the second lateral feed device 20 of the back storage shelf 4b includes a first over-row prevention pin 27 as a first over-row prevention member provided in the vicinity of the engagement pin 26, and the first over-row prevention. A second over-row prevention pin 28 is provided as a second over-row prevention member that is located on the opposite side of the first row prevention pin 27 apart from the pin 27.
[0029]
Then, as shown in FIG. 2 (a), in a state where the pallet P is not stored in the back storage shelf 4b on the back side of the front storage shelf 4a, the first row prevention pin 27 is connected to the front storage shelf 4a. The pallet P is positioned by the first over-row prevention pin 27 so that the pallet P, which is positioned above the endless chain 22 between the rear storage shelf 4b and delivered from the transport carriage 6, does not exceed the storage area of the front storage shelf 4a. The movement is restricted. The engaging pin 26 is in a close position below the first row prevention pin 27. The second over-row prevention pin 28 is located at the back end of the back storage shelf 4b.
[0030]
In the pallet P paid out to the front storage shelf 4a, the engagement pin 26 engages with the groove p2 of the engaged piece p1 by the chain drive of the second lateral feed device 20, and the right side in FIG. As shown, it is pulled into the back storage shelf 4b. In this state, the second over-row prevention pin 28 moves to the upper side of the endless chain 22 between the front storage shelf 4a and the back storage shelf 4b. The first row prevention pin 27 is located at the back end of the back storage shelf 4b.
[0031]
Therefore, as shown on the right side of FIG. 2 (b), in the state where the pallet P is stored in the back storage shelf 4b on the back side of the front storage shelf 4a, as shown on the left side of FIG. When the pallet P is paid out from 6 to the front storage shelf 4a, the pallet P thus delivered hits the second over-row prevention pin 28 and stops. That is, the pallet P discharged from the front storage shelf 4a does not interfere with the pallet P of the back storage shelf 4b beyond the storage area of the front storage shelf 4a so that the pallet P Movement is restricted, and a gap is formed between both pallets P.
[0032]
Further, the lateral feed speed of the second lateral feed device 20 is set slower than the lateral feed speed of the first lateral feed device 11. Thus, when a command for pulling out the pallet P from the back storage shelf 4b is issued in a state where the pallet P is stored in both the front storage shelf 4a and the back storage shelf 4b, the first lateral feed device The two pallets P are prevented from coming into contact with each other even if the 11 and the second lateral feed device 20 are activated simultaneously.
[0033]
Thus, in this embodiment, the chain carrier type first lateral feed device 11 is mounted on the transport carriage 6, and the chain carrier type second lateral feed device 20 is also installed on the back storage shelf 4b. Therefore, the structures of the lateral feed device and the pallet P can be unified, and the equipment cost can be greatly reduced as compared with the case where different types of lateral feed devices are employed. In addition, since both the first lateral feed device 11 and the second lateral feed device 20 are of the chain carrier type, the pallet P can be immediately laterally fed as soon as the endless chains 13 and 22 are driven. It is possible to improve the loading / unloading efficiency by eliminating the loss time as in the case of the horizontal feeding device.
[0034]
Further, in this embodiment, the first lateral feed device 11 of the transport carriage 6 is chain-driven by the first geared motor 17, and the second lateral feed device 20 of the back storage shelf 4 b is chained by the second geared motor 25. Since the carriage 6 is not driven to the side of the front storage shelf 4a, the front storage shelf 4a and the rear storage shelf 4b are used by the second lateral feed device 20 of the back storage shelf 4b even if the transport cart 6 is not waiting on the side of the front storage shelf 4a. The pallet P can be laterally fed in preparation for the subsequent loading / unloading operation, and the loading / unloading efficiency can be further improved.
[0035]
Further, in this embodiment, when the pallet P is not stored in the back storage shelf 4b, the first row is prevented from exceeding the storage area of the front storage shelf 4a so that the pallet P paid out from the transport cart 6 does not exceed the storage area of the front storage shelf 4a. Since the movement of the pin 27 is restricted, the pallet P delivered from the transport carriage 6 to the front storage shelf 4a can be positioned at a normal position of the front storage shelf 4a. By driving the chain 20, the engaging pin 26 can be reliably engaged with the groove p <b> 2 of the engaged piece p <b> 1 of the pallet P, and the pallet P can be reliably laterally fed to the inner storage shelf 4 b. Further, in a state where the pallet P is stored in the back storage shelf 4b, the pallet P paid out from the transport carriage 6 does not interfere with the pallet P of the back storage shelf 4b beyond the storage region of the front storage shelf 4a. Since the movement restriction is made by the second over-row prevention pin 28, the interference between the pallet P of the back storage shelf 4b and the pallet P paid out to the front storage shelf 4a from the transport carriage 6 is prevented. Can do.
[0036]
In addition, in this embodiment, the second lateral feed device 20 is located close to the inside of the guide roller 10 that supports the side where the front and rear weight of the vehicle C mounted on the pallet P in the back storage shelf 4b is large. Since it is provided only at one location and corresponds to the end in the longitudinal direction, not near the center of the pallet P, the pallet P is difficult to bend even if the weight of the vehicle C is applied. In order to prevent interference with the storage shelf, it is not necessary to secure an extra ceiling height of the storage shelf, and the storage portion 1 can be set shallower by that amount. Further, the cost can be halved compared to the case where the second lateral feed device 20 is provided on both sides.
[0037]
Furthermore, since the transverse feed speed of the second transverse feed device 20 is set slower than the transverse feed speed of the first transverse feed device 11, the first transverse feed device 11 and the second transverse feed device 20 are activated simultaneously. Further, the two pallets P of the front storage shelf 4a and the back storage shelf 4b can be prevented from contacting each other.
[0038]
In addition, in this embodiment, although the case where the mechanical parking apparatus was a plane reciprocating parking apparatus was illustrated, if it is a mechanical parking apparatus having a plurality of storage shelves before and after the conveyance path, the elevator slide parking The present invention can also be applied to other mechanical parking devices such as devices and elevator parking devices. Further, the number of rows arranged before and after the storage shelf is not limited to two, and may be three or more.
[0039]
【The invention's effect】
As described above, according to the present invention, since the chain carrier type lateral feed device is provided on both the transport means and the storage shelf excluding the front storage shelf on the transport path side of the storage shelf, the structure of the lateral feed device and the pallet is provided. Can be unified and an inexpensive apparatus can be obtained. Further, the chain carrier type lateral feed device can efficiently feed and unload the pallet simultaneously with the driving of the device. In addition, the lateral feed device is provided only at one position that is close to the inside of the guide roller that supports the side where the front and rear weight of the vehicle mounted on the pallet is large in the storage shelf excluding the front storage shelf on the conveyance path side. The pallet is difficult to bend even if the weight of the vehicle is applied, so that the pallet is not bent. There is no need to secure the ceiling height, and the storage portion can be set shallower by that amount. In addition, the cost can be halved compared to the case where the transverse feeding device is provided on both sides. Furthermore, since the transverse feeder is installed only on the side front and rear heavy weight vehicles, be provided with a transverse feeder on only one side, the generation of a force to incline the vehicle pallet obliquely in plan view as much as possible suppressed, smooth Can be moved straight.
