The present invention relates to a palletless rack type parking system which parks a large amount of vehicles in a rack for loading and unloading without using a separate transport pallet. Preferably, the present invention relates to an entry / exit rack of a palletless parking system that is installed in a rack loading space of a rack and functions as a waiting space for loading / unloading a vehicle that is received from or outside the rack. .

With the spread of automobiles, there was an absolute shortage of parking spaces, which caused traffic congestion, air pollution, and parking difficulties. In particular, in urban centers with a lot of traffic, the limited parking space inevitably increases the difficulty of parking.

As a result, various efforts have been made to solve the parking shortage by mandating the installation of parking lots in each building to cope with the rapidly increasing parking demand. However, due to the limited land, the expansion of parking facilities is bound to reach its limit.

Therefore, as a way to efficiently store a large number of vehicles in a small space, a parking system for storing vehicles on a floor by a mechanical device has been widely used.

Such a parking system is divided into a circulation type, a puzzle type, and an elevator type according to a driving method, and an elevator type is mainly used due to an advantage of allowing a vehicle to be easily, quickly, and shipped in and out.

The elevator parking system installs racks having a plurality of loading spaces in a grid at regular intervals, and has a transport device such as a lift or a stacker crane for transporting vehicles in the spaces between the racks. For example, a fixed code number is assigned to a vehicle and a loading table, and the vehicle is automatically parked and unloaded by interlocking with a control computer.

On the other hand, such an elevator parking system is divided into a pallet method and a pallet-free method according to the presence or absence of a pallet for mounting a vehicle, and the adoption of a pallet-free method, which is more advantageous in terms of structural and arrival and departure time of a vehicle, is gradually increasing.

For example, a non-pallet type parking system can be found in JP-A-5-52058, JP-A5-85953, JP-A-8-120964, and JP-A-10-2004-0024178. It can be seen that this method consists of a rack rack and a fork of a transport device composed of a number of side-by-side bars (bar) by crossing up and down to alternately overlap each other to transfer the vehicle to each other.

However, this method consists of a rack of racks and a fork of a transport device composed of a number of side-by-side bars (bar) to cross each other up and down to alternately overlap each other bar, so that the vehicle stable There is a problem that it is difficult to get in and out and to ensure the safe getting on and off of the occupants.

That is, since the transport fork directly moves the vehicle on the loading fork without mounting the vehicle on a separate pallet, in order to park the vehicle stably in the loading fork of the rack, it must be carried out at the correct position. Not only is it difficult for a passing vehicle to be in the correct position, but it also carries the risk that the occupant must walk on an unstable loading fork.

The present invention was devised to solve the above-mentioned conventional problems, so that the vehicle installed in the rack of the pallet-free parking system can be stably transferred to a transport device such as a stacker crane stably at a correct position. The purpose is to provide a loading and unloading rack of a palletless parking system that allows passengers to get on and off safely.

In order to achieve the above object, the pallet loading / unloading rack according to the present invention includes a rack having a plurality of loading forks, and a stacker crane for loading or withdrawing a vehicle to the rack. In the pallet-free parking system including a rack, the fork of the rack and the transport fork of the stacker crane alternately overlap each other to move the vehicle up and down,

A plurality of fork bars arranged side by side at regular intervals to be orthogonal to the traveling direction of the vehicle, spaced apart from each other to support only the front and rear wheels of the vehicle, and forming a front and rear fork group; An entry and exit passage of the carrying fork formed of narrow and long spaces open toward the carrying fork so that the fork bars of the carrying fork are moved in and out one by one between the fork bars; High information for arranging orthogonal to the fork bars, and fixing each fork bar at the bottom of the fork bar so that the passage end of the fork bar has a cantilever shape; A plurality of rollers installed at predetermined intervals along the longitudinal direction so that the rotation centers are placed in the width directions of the fork bars, and the main surface protrudes from the upper surface of the fork bars and is in rolling contact with the wheels of the vehicle; A floor installed above the high information on the loading space of the rack except the front and rear fork groups; It is characterized in that it comprises a; and the entrance and exit position adjusting means for properly moving the vehicle on the fork bar in the longitudinal direction of the fork bar to be placed in a predetermined wearing or leaving position.

According to one preferred feature of the present invention, the entry and exit position adjusting means, a pair of guide rails are installed side by side at intervals between the two high information, and the guide rail is supported between the two guide rails Slider reciprocating along the road, and a plurality of side by side to be alternately positioned with the fork bar on the slider and protrudes between each fork bar at the time of entry and exit of the vehicle to push the wheels of the vehicle on the fork bar to the left or right It consists of a push bar and an actuator for raising and lowering these push bars.

According to another preferred feature of the present invention, the fork bars are provided with protrusion tabs of an appropriate height at the bottom thereof, and are connected to the respective high information through the protruding tabs to allow transporting forks such as stacker cranes to pass over the high information.

Accordingly, the present invention, it is possible to reliably transfer the vehicle in or out of the pallet-free parking system in the correct position of the stacker crane, as well as the passengers can safely get on and off the pallet-free It has a great effect on the ease of getting in and out of the parking system and improving the speed and reliability.

Such specific features and other advantages of the present invention will become more apparent from the following description of the preferred embodiments with reference to the accompanying drawings.

1 and, no pallet mount type parking system where the mounting table (1) Shipping & Receiving of the present invention is applied (S) as shown in Figure 2, multiple loading fork to the bottom storage space consists of a lattice (L _F ) to have the rack is spaced horizontally (R), and enters the side of the loading fork (L _F), - the lifting-retracted, carrying a loaded or withdrawn with respect to the fork (L _F) loading the vehicle (V) the fork (T consists _F) have between two adjacent racks (R) of the stacker crane is driven in the three axis directions (S _C a).

The illustrated configuration is Korean Patent Publication No. 10-2004-0024178, which is the applicant's prior application, wherein the loading forks L _F of the rack R are properly spaced from each other to support only the front and rear wheels of the vehicle V, respectively. It is divided into the front fork group F ₁ and the rear fork group F ₂ .

The loading / unloading loading table 1 of the palletless parking system according to the present invention is preferably installed directly in any loading space of the rack R, for example, on the first floor of the entrance side edge of the rack R. do.

As shown in Figs. 3 to 6, the loading and unloading loading table 1 is basically a plurality of fork bars 10 which are arranged side by side at intervals, and between the fork bars of the transport forks T _F. Entry and exit passages (P _a ) of the transport forks formed of narrow and long spaces that are open toward the transport forks so that the fork bars are moved in and out one by one; Arranged and orthogonal to these fork bars 10 to fix each fork bar 10 to the rack R, and the roller 20 which is supported so that the main surface protrudes upward on each fork bar 10 ( 30), the floor 40 covering the high information 20 of the loading space excluding the fork bar 10, and the vehicle V placed on the fork bar 10 laterally along the roller 30. It is comprised with the entrance and exit position adjustment means 50 which slides suitably.

The fork bar 10 has a front fork group 10a that supports the front wheels W _f of the vehicle V and a rear fork group that supports the rear wheels W _r , similarly to the loading forks L _F of the rack R. (10b) is arranged at intervals, the entry and exit passage of the conveying fork formed of narrow and long spaces open toward the conveying fork so that the fork bar of the conveying fork (T _F ) one by one between the fork bar between To form (P _a ). As shown in FIG. 5, the front fork group 10a determines the stop position of the vehicle V and maintains stable support so that each fork bar 10 corresponds to the outer circumference of the front wheel W _f . It is configured to form an arc, and the rear fork group 10b is configured to have a wide width so as to park all the vehicles V having different lengths.

The fork bar 10 may be formed in various forms in consideration of the installation of the roller 30 together with its structural stability.

First, as shown in Figs. 7 and 8, it has an approximately U-shaped cross section to accommodate most of the roller 30 therein, and the rotation shaft 31 of the roller 30 is coupled to both side walls 11 thereof. The support hole 12 is formed.

However, the fork bar 10 having such a structure is open at the top thereof, and foreign substances may accumulate on the inner bottom after prolonged periods, which may prevent the rotation of the roller 30, and the bottom 13 of the fork bar 10 A plurality of foreign matter discharge holes 14 are formed along the longitudinal direction as foreign matter deposition preventing means.

On the other hand, the foreign matter deposition prevention means as shown in Figures 9a and 9b by covering the cover 15 so as to expose only a part of the main surface of the roller 30 to the upper opening of the fork bar 10 is configured to block the foreign matter inflow itself Alternatively, as shown in FIG. 9C, the foreign matter discharge hole 14 may be formed in the bottom 13 of the fork bar 10, and the upper opening may be covered with the cover 15. .

In addition, when the roller 30 is damaged due to prolonged use, the roller 30 may need to be removed from the fork bar 10 to be repaired or replaced, for example, as shown in FIGS. 10A and 10B. Cover 15 for opening the upper portion of the support hole 12 formed in the side wall 11 for easy separation of the support hole 12 to form a U-shaped groove, and covers the upper opening of the fork bar 10 Vertically provided with a plurality of pressing pieces 16 supporting the pressing shaft 16 of each roller 30 from above on both side edges of the roller 30 to prevent foreign substances from entering and detaching the roller 30. Disassembly can also be ensured.

Such fork bars 10 may be directly attached to the high information 20 by welding, but the fork bar 10 is provided with a roller 30 and the like, so that the high information ( 20) is preferably attached. To this end, for example, as shown in FIG. 7, the forkbars 10 are bonded onto two binder beams 18 in the form of channels arranged side by side to be orthogonal thereto, and these binder beams ( 18 may be coupled to insert the corresponding high information 20 and fastened with bolts 23.

On the other hand, as shown in Figures 1 to 3, in the case of the intermediate rack (R ₂ ) is mounted in two rows of vehicles (V), the transport fork (T _F ) to enter from both sides of the loading fork (L _F ), respectively In this case, since the entrance and exit of the occupant of the loading fork (L _F ) is considerably dangerous, in the loading and unloading loading table 1 of the present invention, the transport fork (T _F ) is formed of narrow and long spaces open toward the fork By entering only one side of the entry and exit passage (Pa) of the transport fork is to secure the spare portion of the fork bar 10 to the passenger's passage.

This is because the loading / unloading rack 1 of the present invention functions as a temporary waiting space of the vehicle V simply entering and leaving the vehicle V, rather than parking the vehicle V like the other loading forks L _F of the rack R. This is because the transport fork T _F of the stacker crane S _C does not necessarily have to enter and exit from both sides, and also to increase the safety of the entry and exit of the vehicle V as much as possible.

Here, in the case of the outer rack (R ₁ ) there is no space to secure the passage of the occupant is secured by expanding the passage separately on the fixed end side of the fork bar 10 as shown in FIG.

The high information 20 is the middle of one end of the fork bar 10, regardless of whether or not the loading and unloading rack 1 of the present invention is installed in the rack (R ₁ ) located on the outside or in the rack (R ₂ ) located in the middle It consists of two first and second high information (21, 22) fixed to the lower portion of the fork bar 10 is configured to take the cantilever form.

Here, both ends of each of the high information (21, 22) is bonded to the two short-sided horizontal beam (B) and the post (P), respectively, connecting the posts (P) of the rack (R), accordingly preferably Each of the old information 21, 22 may be replaced by a horizontal beam on the long side of the rack (R).

On the other hand, since the second height information 22 supports the approximately middle lower portion of the fork bar 10, the transport fork T _F of the stacker crane S _{C is} connected to the fork bar 10 for the transfer of the vehicle V. There is a need for adequate operating margin to avoid overlapping entry, lift and retraction.

Such a working margin may be secured by fixing the support beam with a protrusion tab of an appropriate height in the middle of the fork bar bottom of the transport fork (T _F ), or protruding at the bottom of the fork bar 10 of the loading table 1. It is also possible to secure it by providing the tab 17 and connecting it on the high information 20, or by providing the projection tab in both.

In addition, since the second height information 22 bears the most load of the vehicle V in its position, deflection for measuring the amount of deflection of the second height information 22 in the center thereof, as shown in FIGS. 4 and 5. By installing a weight sensor such as a detector (90), by measuring the load of the vehicle (V) as a result of the detection of the deflection detector (90) at the time of wearing the vehicle (V) by controlling the operation of the stacker crane (S _C ) accordingly It is desirable to determine whether the vehicle (V) is wearing.

In this case, when it is determined by the deflection detector 90 that the load of the vehicle V exceeds a certain load, an alarm buzzer (not shown) and / or an alarm that notifies the driver or manager of the overload load by signaling the signal Etc. can be provided together.

The roller 30 has the fork bar 10 so that the rotating shaft 31 is rotated in a direction orthogonal to the vehicle V entry direction by being mounted on the support holes 12 formed in the two side walls 11 of the fork bar 10. To be simply supported, a plurality of dogs along the longitudinal direction of the fork bar 10 are arranged at regular intervals.

At this time, when the distance between each roller 30 is too wide or excessively protrudes to the upper portion of the fork bar 10, the sliding of the vehicle V and the sliding to the side is not smooth and smooth, so that the possible roller 30 It is desirable to protrude only as high as possible to move the clouds while closing the gap.

The floor 40 is installed to surround the upper end of the high information 20 and the fixed end side of the fork bar 10 except the front and rear fork groups 10a and 10b in the loading and exit loading space. The floor 40 has the same level as the upper surface of the fork bar 10, and preferably, the floor 40 around which the transfer of the vehicle V is not made is blocked by the wall 41 for the safety of the occupant, The upper part of the floor 40 installs the ceiling 42.

Entry and exit position adjustment means 50 may be configured in various forms. For example, as shown in Figs. 11 and 12, between two guide rails 51 and two guide rails 51 that are installed side by side at intervals between two pieces of high information 21 and 22, respectively. A slider 52 supported and traveling, and a plurality of push bars 53 supported on the slider 52 and selectively projecting on the fork bar 10 to push and move the vehicle V to the left or the right; And an actuator 54 for elevating the push bar 53.

The guide rails 51 are formed in a channel shape, and both ends thereof are fixed to two pieces of high information 21 and 22 so that the openings face each other.

The slider 52 has a plurality of wheels 55 each inserted into the guide rails 51 corresponding to both sides to move in a cloud, and a driving motor 56 connected to the wheels 55 so as to be electrically connected to one side thereof. To reciprocate between the two pieces of old information 20.

The push bars 53 are installed on the fixed plate 57 so as to be alternately positioned with the fork bar 10, and both ends of each push bar 53 are caught by the wheels W _f of the vehicle V. The groups 53a are formed to protrude upward, respectively.

These push bars 53 hingely connect one end of the fixed plate 57 to the slider 52 by the link 58, and the other end of the fixed plate 57 is installed in the piston rod of the actuator 54 perpendicular to the slider 52. It lifts with respect to the fork bar 10 by fixing to 54a.

By the way, the vehicle (V) is to be set to the exact position, regardless of its size, preferably the wheel (W) of the vehicle (V) sliding to the side at the time of entry and exit at approximately the middle of the upper surface of each fork bar (10) _f ) A sliding stop tab 59 for frictionally contacting (W _r ) and limiting the sliding thereof is provided to protrude.

That is, at the time of the wearing, the wheels W _f and W _r of the vehicle V are blocked by the sliding stop tab 59, whereby the wearing position is set.

However, not all vehicles V are set at the entry and exit positions by the sliding stop tab 59 regardless of the width thereof, and the sliding stop tab 59 merely determines the limit position at which the vehicle V slides to the wearing side. Substantially sliding of the vehicle V is performed by the driving stroke of the slider 52 using the above-described push bar 53.

Therefore, depending on the width of the vehicle V, the wheels W _f (W _r ) may stop without reaching the sliding stop tab 59, in particular, the inertia acts on the vehicle V sliding on the roller 30. Even if the sliding stop tab 59 will not be exceeded.

The sliding stop tab 59 protrudes from the upper surface of the fork bar 10 to be equal to or slightly higher than the protruding height of the roller 30, and has excellent frictional force to effectively prevent slippage of the wheels W _f and W _r . It is preferably composed of a material.

Here, although only one sliding stop tab 59 may be provided in each fork bar 10, preferably, the auxiliary sliding stop tab 59a is disposed outside the free end outermost roller 30 of the fork bar 10. It is further provided. This is because when the width of the vehicle V is considerably large, when one wheel W _f (W _r ) of the vehicle V comes into contact with the main sliding stop tab 59 provided in the middle of the fork bar 10 and stops, the vehicle ( V) is to prevent excessively biased toward the free end of the fork bar (10) or detached from the fork bar (10).

On the other hand, a stopper 60 is further provided on the downstream side of the front fork group 10a of the loading / unloading loading table 1 to prevent excessive entry of the vehicle V, which preferably enters. The stopper 60 may be configured in various forms. For example, as illustrated in FIG. 13, the front wheels W _f of the vehicle V are located on the downstream floor 40 of the front fork group 10a. It may be composed of a wheel stop roll 61 to block the entry in contact with.

However, since the distance between the front wheel (W _f ) and the front bumper is different depending on the vehicle type, even if the front wheel (W _f ) is caught by the wheel stop roll 61 in the case of large vehicles, the front bumper is a post (P) of the rack (R) There is no fear of bumping into).

Therefore, more preferably, a bumper stop wall 62 is further installed at an appropriate height on the downstream side of the wheel stop roll 61 to restrain the entry by contacting the front bumper of the vehicle V so that the wheel stop roll 61 and the wheel stop roll 61 are provided. Together, it prevents excessive entry regardless of the vehicle type to protect the rack (R) and to prevent the vehicle (W _f ) and the bumper does not fit the rack (R) is not worn.

The remaining 70 is a drop prevention jaw installed at the edge of the floor 40 on the side of the stacking crane S _C carrying port T _F , and the 80 is installed at both sides of the inlet of the loading / unloading table 1. It is a buffer post for protecting the rack R from a collision of the vehicle V that may occur.

Next, the operation of the loading and unloading loading table of the pallet-free parking system according to the present invention configured as described above will be described with reference to FIGS. 3 and 14A to 15E.

First, in the case where the vehicle V is put on, the vehicle V enters into the rack-mounting rack 1 of the rack R from the outside, and the front wheel W _f of the front fork group of the stacking table 1 10a) stop the vehicle (V). At this time, the fork bar 10 of the mounting table 1 is the same size as the loading space of the rack R capable of loading the vehicle V in two rows, and thus only one vehicle V enters and exits, thus being very safe and easy. You can enter.

The wheel stop roll 61 in contact with the front wheel W _f of the vehicle V and the bumper stop wall 62 in contact with the front bumper are provided on the downstream side of the front fork group 10a. The front wheels W _f and the rear wheels W _r of the vehicle V are secured on the front and rear fork groups 10a and 10b of the loading table 1 while effectively preventing excessive entry of the vehicular vehicle V. Put on.

After the vehicle V stops at the fork bar 10, the occupant gets off and exits safely through the passage of the floor 40.

At this time, the entrance and exit position adjusting means 50 is completely moved toward the fixed end of the fork bar 10, as shown in Figure 14a so that the lifting end of the push bar 53 is the wheel (W _f ) (W _r ) of the vehicle (V) ) Will be lowered so as not to interfere.

In this state, after the passenger gets off and exits, the driving motor 56 of the slider 52 is driven so that the slider 52 moves freely along the guide rail 51 as shown in Fig. 14B. The vehicle is driven toward one end, and thus the engaging protrusion 53a provided at the fixed end of the push bar 53 contacts the front and rear wheels W _f and W _{r of} the vehicle V so that the vehicle V is connected to the fork bar. 10) to the free end.

Then, the wheels W _f (W _r ) of the vehicle V placed on the rollers 30 protruding to the upper portion of each fork bar 10, the thrust of the push bar 53 as the slider 52 travels. By sliding the rollers 30 by sliding to the free end of the fork bar 10.

Subsequently, as shown in FIG. 14C, after the slider 52 moves toward the second height information 22, the driving motor 56 stops and the wheels W _f and W _r of the vehicle V slide. Stops. At this time, the right and left widths of the vehicle V are particularly large, and the wheels W _f and W _r contact the sliding stop tabs 59a before the slider 52 is completely moved so that the sliding is stopped and the vehicle V is worn. Is rejected.

In addition, when the deflection detector 90 installed in the center of the second height information 22 measures the weight of the vehicle V, the wearing is also rejected when the measured weight exceeds the set allowable weight, and an alarm is issued accordingly. do.

After the normal arrival, the driving motor 56 is driven in the reverse direction, and as shown in Fig. 14D, the slider 52 moves completely toward the first height information 21, and this is caused by the slider 52 being the second height. This is because when it is located at the bottom of the information 22, it interferes with the entry of the transport fork (T _F ).

Next, after the slider 52 has returned to the initial position, the stacker crane S _C which is in standby is operated, and as shown in Fig. 14E, the transport fork T _F is moved to the fork bar 10 of the mounting table 1. ), The vehicle is transported to the loading fork L _F of the empty rack R after the vehicle V is transferred, retracted and retracted horizontally through the entry and exit passage of the transport fork T _F.

On the other hand, when the vehicle V is shipped, the above-described wearing operation is reversed as shown in Figs. 15A to 15E. That is, when the shipping signal drops, the stacker crane S _C moves to the loading fork L _F of the rack R, moves the vehicle V on the transport fork T _F , and loads the vehicle V on the transport fork T _F , as shown in FIG. 15A. The vehicle V is transported onto the loading and unloading rack 1 by moving in and out and retracted horizontally through the entry and exit passage of the transport fork T _F to move.

Subsequently, as shown in FIG. 15B, the slider 52 located on the first height information 21 travels toward the second height information 22, whereby the fixed end locking projection 53a of the push bar 53 is moved. It stops when caught by the wheels W _f (W _r ) of the vehicle V placed on the fork bar 10.

After the slider 52 moves to the bottom of the first height information 21 and stops, the actuator 54 is operated as shown in Fig. 15C to push up the free end of the push bar 53 upwards. Accordingly, the free end of the push bar 53 protrudes upward between the fork bars 10 to maintain a horizontal state.

Thereafter, the driving motor 56 is driven in the reverse direction so that the slider 52 is moved toward the first height information 21. Accordingly, as shown in FIG. 15D, the free end locking protrusion 53a of the push bar 53 is moved. Is pushed toward the fixed end of the fork bar 10 by walking the inner surface of the wheel (W _f ) (W _r ) of the vehicle (V).

Then, the wheels (W _f ) (W _r ) of the vehicle (V) placed on the rollers 30 protruding onto the fork bar (10) is sliding while rotating the roller 30, the slider 52 Reaches the first height information 21, the driving motor 56 stops and the wheels W _f (W _r ) pushed by the push bar 53 stop.

After the vehicle V is stopped at the shipping position, as shown in Fig. 15E, the actuator 54 is turned off to lower the free end of the push bar 53 again, and in this state the driver Boarding V) to exit the loading platform (1) to complete the delivery.

As described above, according to the loading and unloading rack of the pallet-free parking system according to the present invention, a vehicle, which is loaded or unloaded, can be stably transferred at a precise position where a transport device such as a stacker crane is set. You can get on and off safely.

In addition, since only one vehicle enters and exits a loading space capable of parking in two rows, a waiting space for entry and exit is secured to facilitate entry of the vehicle, and in particular, the wearing position and storage position of the vehicle can be kept constant.

Therefore, the present invention has a very excellent effect that greatly contributes to the ease of entering and unloading and reliability of the parking vehicle in the palletless parking system.
