The present invention relates to a three-dimensional parking device, in particular sliding and hooking bottle-type conveying (Sliding, Hooking) configuration of the pallet traverse device provided in the cart (Cart), lift and pallet in a multi-level multi-level flat reciprocating parking lot using a pallet Conreying) is characterized by the configuration.

As is well known, the multi-level multi-level flat reciprocating parking lot using pallets can be classified according to the arrangement of lifting lifts or the characteristics of pallet traversing devices provided in carts and lifting lifts. The advantages and disadvantages of substituting the lifting lift arrangement method are as follows.

34 to 35 degrees show the format of the multi-tiered multi-plane flat reciprocating parking lot value by the arrangement of lifting lifts.

FIG. 34 illustrates a case in which the cart 100 is installed at a cart driving path 110 in the center, and the left and right row parking lots 220a and 220b are arranged horizontally on both sides thereof, and the lifting lift is also left and right lifting lift 300c. (300d) is a two-sided arrangement that must be installed on both sides, respectively, the left column lifting lift (300c) to the left column parking lot (220a) side, the right column lifting lift (300d) only crosses the pallet to the right column parking (220b) side As a form which can be used, this form is a format in which the pallet transverse device provided in the cart 100 and the lifting lifts 300c and 300d can move the pallet only in one direction.

FIG. 35 illustrates that in the case where the cart 100 is installed in the cart driving path 110 in the center and the left and right row parking lots 220a and 220b are arranged side by side on both sides of the cart driving path 110, only one lifting lift 300 is provided on either side. As a side-by-side arrangement method, the cart 100 transversely exchanges one lifting lift 300 and the pallet to move the pallet horizontally by using the left and right row parking lots 220a and 220b on both sides. As a form of this, the pallet traversing device installed in the cart 100 can move the pallet in both directions.

The basic configuration of the multi-level multi-level flat reciprocating parking lot using pallets is formed of parking lots, carts, lifting lifts and pallets.

Parking lots are partitioned into appropriate spaces so that pallets can be stacked, and they are installed in vertical and horizontal rows according to the direction in which pallets enter and exit each floor across multiple floors.

The cart is installed on the runway that is in contact with the rows of parking lots on each floor. Although there are some differences depending on the type of the parking lots and the lift lifts, the cart is a flat driving system that flatly reciprocates between the parking lots of the lift lifts and the lift lifts. It is equipped with a pallet transversing device which transfers a pallet (car) to a cart and parks it on a parking lot, or, conversely, a pallet (car) parked on a parking lot is loaded on a cart and reloaded on a lifting lift.

The configuration of the lifting lift is controlled to move up and down by a known lifting device, and serves only to vertically transfer the car between the car entrance and each parking floor. The lifting lift is installed in one space or divided into separate spaces during the parking row.

In the multi-level multi-level flat reciprocating parking lot formed with this basic configuration, the arrangement of the parking lot and the lift lift, which determines the cost, economics, the number of cars, and the constructability of the parking lot, uses pallets between the cart and the lift lift or between the cart and the parking lot. There are many restrictions due to the construction of the pallet traversing device.

Representative pallet traversing devices provided so far include a so-called vertical hook type shown in 38 to 40 degrees, a slide reciprocating type by a double rack pinion shown in 41 to 43 degrees, and a push shown in 44 and 45 degrees. (PUSH) expressions are provided.

In the vertical hook (hook) shown in FIGS. 38 to 40 degrees, the sprockets 13, 14 and 15 are respectively installed at the front and rear ends of the cart 72b. Vertical hooks 11 and 12 are attached to the chain 10 in a symmetrical manner, and the pallet 80 placed by the wheels 81 on the parking stand 20 has a bracket 83 below the side facing the cart 72b. The hook 11 attached to the chain 10 by rotating the sprockets 13, 14, 15 in the direction of the arrow in the cart 72b as shown in FIG. (12), the transfer pin 84 of the pallet 80 is pulled toward the cart 72b side, and the pallet 80 is horizontally transversely mounted on the cart 72b like the hummer 11, or, conversely, the cart 72b. The sprockets 13, 14 and 15 of the cart 72b are rotated to the opposite side by rotating the pallet 80 mounted on the hook 11 above. Moving the pallet 80 in the opposite direction to the parking lot ( 20) can be reduced to the configuration.

Reference numeral 11a denotes the tip of the hook, 11b denotes the transfer pin restraint of the hook, and 11c denotes a fixing portion that fixes the hook to the chain 10, and 22 denotes a parking stand 20. The guide rail of (77) is the guide rail of the cart (72b), (H) is the operating height of the cart, (H1) is the height of the cart device portion, (H2) is the height of the chain row.

The characteristic characteristics of the vertical hook-type pallet traverse device of this configuration is that the guide rail 22 and the wheel 81 load the pallet 80 even under a heavy load in which the vehicle 80 is mounted on the pallet 80. By dispersing in and transporting by the hooks 11 and 12, the drive unit of the pallet transverse device can be configured to have a relatively simple and inexpensive low output type, and the cart 72b can be Advantages of minimizing the waiting time to exhibit a high feed rate, the pallet holding state of the hooks (11) and (12) during the transfer of the pallet 80 is firmly constrained in the pallet transfer direction or at right angles to the transfer, so there is no fluctuation and stability This high and the advantage of being able to precisely stop the position, and the trajectory to pull the transfer pin 84 to the hook (11) (12) is formed as a cam diagram to converge the transfer pin 84 to a certain groove, the transfer pin (84) ) Position is incorrect It can be easily pulled even if it is prevented from malfunctioning, and the process is reduced and the structure is simplified in the transverse movement of pallets, so it has excellent reliability and maintainability with low malfunction and defect rate compared to other types controlled by many sensors. Although there are advantages, the transverse movement of the pallet 80 can be reduced and re-entered in the direction pulled back to the hooks 11 and 12, but it cannot be moved to the opposite side, so that the lifting lift can be moved as shown in FIG. 34. Although it can be employed to form a single side array type as shown in Figure 35 there is a disadvantage that can not be employed.

In addition, the chain (10) of the caterpillar chain (10) attached to the hook (11) 12, which is the main configuration of the pallet traversing device is a cart 72b because the chain row height (H2) is significantly increased by the tension sprocket (15) ) Height (H1) and working height (H) also increases proportionally.

As is well known, the cart 72b installed on each floor should have a certain height so that the carts on the upper and lower floors do not interfere with each other when the car is mounted and run on a car. The height from the low floor lifting lift, which is the unit floor height, to the rising pallet surface is also increased. Accordingly, the number of parking floors within the effective building height is reduced, so the space utilization rate is very low, and the number of parking spaces is also reduced.

41-43 shows the structure of the slide reciprocating pallet transverse apparatus by the double rack pinion.

The cart 72a reciprocating between the parking lots 20 is provided with multi-stage sliders 51 and 52 which are expanded and contracted in a scope type, and the slider is moved to the parking lots 20 on the left and right to pallet with clamps 53 installed on the sliders. It is the structure which became able to transversely move the pallet by walking the step piece 82 of (80).

The main components of the pallet transverse system are fixed with three racks 56, 57, 58 and one pinion 59 in the super gear 66 rotated by the transfer motor 64 as shown in FIG. Roller guide groove 61 of fixed guide 60 fixed to frame 75, consisting of a double stroke differential mechanism that combines guide 60, 1-stage slider 51, and 2-stage slider 52. The first and second sliders 51 and 52 are installed in the cart by the slider roller 62 guided to the left and right parking lots and the lift side.

In the middle portion of the two-stage slider 52, a clamp 53 is mounted to the upper surface by a solenoid operating mechanism.

This clamp protrudes when the two-stage slider 52 is fed to the bottom of the pallet 80, and is fitted in the fitting piece 82 formed on the bottom of the pallet 80. As shown in FIG.

In this configuration, the pallet traverse device installed in the cart 72a is operated by operating the feed motor 64 in the forward and reverse directions while the cart 72a is stopped. The second stage slider 52, which is slid upward in proportion to the movement distance of the first stage slider 51, which is moved to the single slider 51, is moved, and the reduction operation of the second stage slider 52 is performed by the transfer motor ( If the rotation control 64 is reversed, the differential gear train is operated in the opposite direction to the above operation to perform the left and right multistage telescopic telescopic operation of reducing the two-stage slider 52 to the correct position of the cart 72a.

In addition to the operation control of the pallet traverse device, the basic step of transversely moving the pallet 80 in the parking lot or the lifting lift onto the cart 72a is to move the two-stage slider 52 in the stopped state of the cart 72a. 80) Go to bottom → Solenoid operation → Insert clamp 53 into step 82 of pallet 80 → Reduction operation of two-stage slider 52 → Position of two-stage slider 52 on cart 72a The basic process of carrying out the transverse movement completion of the alignment → pallet 80, and the transverse movement of the pallet 80 loaded on the cart 72a by the lifting lift or the parking lot is carried out in the stationary state of the cart 72a. Transversely move the two-stage slider 52 carrying 80) to the parking lot (elevation lift) side → Move the pallet 80 to the parking lot 20 → Arrange the solenoid operation → Remove the clamp 53 from the pallet step piece 82 → Two-stage Reduction of the slider 52 → Sealing of the two-stage slider 52 on the cart 72a It is

A characteristic of such a scope-type reciprocating slider-type pallet traverse device is that the two-stage slider 52 is moved to the bottom of the pallet 80 in both directions of the front and rear parking lots, so that the clamp of the two-stage slider 52 53) can be configured to be pulled into the stepped piece 82 on the bottom of the pallet 80 to be pulled out, so that the arrangement of the lifting lift can be configured not only in both sides but also in one side, and the drive unit of the pallet traverse device is relatively simple and inexpensive. It can be configured as a low output type, and the overall configuration of the pallet traversing device can be accommodated in a frame of relatively low height cart 72a, but there are advantages in that the height of the lifting lift or the cart 72a can be made low. If the step piece 82 is always aligned to a certain position and the extension stroke of the two-stage slider 53 cannot be accurately controlled, the clamp 53 of the slider sets the step piece 82 of the pallet 80. There are drawbacks such as high malfunction and frequent accident rate due to the lack of fastening, which requires precise control and precise manufacturing.In the parking administration for entering and exiting cars, the pallet 80 loaded on the cart 72a is lifted or lifted to the parking side. After the transfer, the two-stage slider 52 must be completely returned onto the cart 72a, and then the next process can be operated. On the contrary, the pallet 80 on the lifting lift or parking lot is transversely moved onto the cart 72a. In this case, since the two-stage slider 52 must be operated to the bottom of the pallet 80 while the cart 72a is stopped, the waiting time of the cart 72a becomes long, and thus the operating time in the traverse device is long. .

In addition, since the basic conveying operation of the pallet 80 by the pallet traversing device must be performed in a number of unit processes and sequential control, the execution time of each process is significantly longer, and thus the overall loading and unloading time is very slow. In the operation control of the pallet traverse device, which is stretched into a shape, it is necessary to perform a multi-stage process with many sensors. Therefore, when operating the solenoid, which is the driving source of the clamp 53 which hangs the pallet 80 while there is a lot of malfunction due to the response error of each sensor, Due to frequent malfunctions, safety, reliability, and maintainability were very low.

The PUSH type configuration shown in FIGS. 44 and 45 is provided with a horizontally arranged two-row trackless chain 30 horizontally on a cart 72c, and a horizontal pallet moving piece 31 ( 32 is attached symmetrically and the pallet 80 is installed with a vertical pin 86 below the side contacting the cart 72c to rotate the chain 30 to control the pallet (31, 32). By pulling the vertical pin 86 of 80, the pallet 80 is configured to transverse to each other from the parking lot 20 to the cart 72c side or from the cart 72c to the parking lot 20 side.

According to this configuration, the conveying operation of the pallet 80 is carried out in a continuous operation, so that the transverse travel time is shortened, and even if there is some gap between the cart 72c and the lifting lift, the length of the pallet moving pieces 31 and 32 is adjusted. Since the pallet 80 can be pulled down, there is less restriction on the selection of the lift lift, and since the pallet can be moved horizontally freely in both the left and right directions, the lift lift can be freely configured not only in both sides but also in the pin side arrangement. Although there is an advantage, the movement of the pallet 80 becomes severe as the moving pieces 31 and 32 installed in the cart 72c do not securely restrain the vertical pins 86 of the pallet. This low, stop position is uncertain, there is a disadvantage that can not perform the next process without a separate brake or alignment device, installed in the chain 30 of the track on the cart (72c) Pallet moving pieces 31 and 32 the transport direction component force when the line pull or push the pallet 80 at a rotational orbit of the chain 30 is smaller consumption component force will have been a lot of large power loss disadvantages.

As described above, it can be understood that the overall characteristics of the parking lot value can be determined by the characteristics of the pallet traverse device in the three-dimensional parking device.

Therefore, it is possible to reduce the cost of the parking lot value in the multi-tiered multi-plane reciprocating parking lot, increase the number of parking lots in the unit space, ease of construction, fast parking speed, and generality of the lift lift arrangement, and the manufacturability of carts and lift lifts. High performance pallet traversing devices were required to satisfy the requirements of economy, maintenance, transport speed, safety, reliability, and operability and to lower the height of the cart.

Accordingly, the present invention has been invented in response to such a demand. As a three-dimensional parking device, in particular, a multi-layer multi-level flat reciprocating parking lot device, mounted on a cart and a lift lift, etc., a pallet transverse device for reciprocating transverse travel of a pallet between a parking lot and a cart and a cart and a lift lift Sliding, hooking Conveying (Sliding, Hooking Conveying) is characterized in that it is configured to have the following purposes.

The first purpose is to reduce the parking speed of the parking lot by constructing the pallet traversing device into a continuous operation type with short operating time.

The second purpose is to allow the cart to be accommodated slowly even if the distance between the cart and the parking lot or between the cart and the lift is far.

The third purpose is to ensure the safety and reduce the noise by minimizing the fluctuations with a certain restraint during conveyance of pallets.

The fourth purpose is to accurately and easily control pallet transfer operation and position control on the cart or on the lift lift to minimize the interference factor and the malfunction rate between the parking administration or the operation of the cart and the lift lift.

The fifth purpose is to allow the pallet to move freely in both directions on the cart so that it is not restricted by the arrangement of lifting lifts.

The sixth objective is to completely eliminate the malfunction rate during the initial towing by allowing a certain amount of pulling to allow for the first towing operation of the pallet.

The seventh object is to reduce the manufacturing cost of parking carts and pallets as well as carts in connection with the above-mentioned purpose.

The eighth purpose is to make the overall height of the pallet traverse lower so that the height of the cart and the floor of the parking lot can be greatly reduced to increase the number of parking spaces in the unit space.

Other objects and effects will become apparent from the drawings and the following description.

Hook rollers (140a, 540a, 540b) and the hooking device can be installed only on one side of either side.

In addition, the hook roller for hooking the pallet during the hooking device may be configured in the following embodiments.

As shown in FIG. 36, the left and right ends of the cart 100 are provided with rotation levers 640 installed freely on the brackets 142, respectively, and the rotation levers 640 are the driving motors of the hooking apparatus described above. In conjunction with, the lower end of the pallet 200 can be configured as a hooking device 600, the roller shaft 602 located in the swing trajectory of the rotary lever 640 freely laid on the bracket 604.

The operation of the hooking device of such a configuration is that the rotary lever 640 installed in the cart 100 rotates in a constant direction by the rotation control of the drive motor, and the front end of the rotary shaft 60 of the roller shaft 602 of the pallet 200. It is to perform a hooking operation to be pulled toward the cart 100 side while sliding in the turning trajectory and placed on the above-mentioned primary transfer rollers 160a and 161a.

The sliding and hooking parallel conveying apparatus of the present invention implemented as described above has the following advantages over the conventional pallet traversing apparatuses mentioned above and other pallet traversing apparatuses not mentioned.

The first advantage is the sliding and hooking parallel conveying method as described above for the construction of the pallet traversing apparatus which carries out the pallet transversal moving process, which is essentially carried out in all types of pallet loading and receiving strokes of the three-dimensional parking apparatus as described above. The process of translating pallets between the parking lot and the cart, and between the cart and the lift lift allows the pallet hooking operation to be immediately carried out by the hooking device without waiting time after arranging the position of the cart 100. In the process of translating pallets to the roller conveying device and transversely moving the pallet from the cart to the parking lot, the lift lift side, and the lift lift to the cart side, the cart is aligned without the hooking device. Immediately after conveying operation by roller conveyor Since the transverse movement process of pallets is carried out in time, the number of unit processes in each type of stroke is shorter than before, and the execution time is significantly shortened, and the unit operation processes performing each stroke are continuously performed without waiting time by simple operation. In the operation control and position control of each device to connect each process only, the operation rate is extremely small, so the control is easy and the control speed can be increased. It is possible to drastically reduce the parking speed, which is an important drawback.

Second advantage is that the characteristics of the pallet traverse device installed on the cart 100 can move the pallet 200 in both directions on the cart as described above, two lifting lifts (300c) (300d) as shown in FIG. In both arrangements installed on both sides of the left and right parking lots 220a and 220b, both parking lots and two lifting lifts 300c and 300d can be used interchangeably, and as shown in FIG. Even in the one-sided arrangement where the lifting lift 300 is installed on only one side of the rear row parking lots 220a and 220b, the pallets can be transferred to both sides of the lifting lift 300 and both sides of the rear row parking lots 220a and 220b. As a result, the arrangement of the lifting lift is not limited. These advantages also add to the advantages of reducing the parking speed, as well as reducing the construction costs of the parking facilities.

The third advantage is that most multi-storey multi-level parking facilities are installed in the structure, a considerable gap is formed between the cart and the lifting lift by the beam 400 of the building, and the conventional pallet traversing device is configured to accommodate this gap. In order to move the various types of transport devices with a separate drive source is installed in each parking floor, the sliding, hooking parallel conveying system pallet traversing device of the present invention cart 100 by the beam 400 of such a building Even though there is a significant gap between the lifting lift 300 and the roller conveyor device 150, 350 to the cart 100 and the lifting lift 300, respectively, as in the configuration and effect of the various embodiments of the present invention described above By installing the pallet 200 transverse movement operation between the cart 100 and the lifting lift 300a by the roller conveying devices 150 and 350 on both sides of the cart 100 and the lifting lift 300, respectively. Since it can be moved to a long distance, the connection roller 410 installed in the beam 400 of the building is composed of idle roller rows in the non-driven state of the installation cost and operating cost of several drive motors for each beam 400 of each floor It is very economical in terms of equipment cost and maintenance in operation compared to installing various types of feed roller rows while installing the rollers. You can set the location.

The fourth advantage is that the pallet is firmly constrained by the hooking device, the roller conveying device, and the side wheels 208 and the slide wheels 206a to b of the pallet 200 during the transverse movement operation. It has the advantage of minimizing the increase of safety, reducing the noise and correct alignment.

Fifth advantage is that the pallet transverse movement and position control on the cart or lifting lift by the hooking and conveying device of the present invention described above is performed by simple movement and simple operation by simple structure. Easy and accurate operation and extremely low failure rate. Accordingly, failure and accidents are minimized by lateral movement of pallet 200, cart and lifting lift, and minimizing interference factor and malfunction rate of adjacent structures during lifting and lifting operation. In principle, it has the advantage of preventing and excellent maintainability.

Sixth advantage is that the left and right hooking devices (130a, 130b) as described above when towing the pallet settled in the parking lot to the side of the circular frame on one side of the pallet (200) And a trail that pulls the rear end of the track is gradually drawn to the cam, so even if there is some error in the alignment of the pallet 200 or the cart 100, it overcomes this and pulls it firmly. This can be prevented completely.

The seventh advantage is that since all the components of the pallet traversing device is configured low on the cart 100, the height of the cart as well as the unit parking floor height can be significantly lowered to significantly increase the number of parking lots in the unit space.

Eighth advantage is that the pallet 200 is used as a bilateral arrangement in relation to the above advantages when moving the space installed in the cart, parking lot, lifting lift and beam 400 of the building to the bottom of the pallet 200 Since the frame surface of the pallet 200 is used without providing a separate rail, the structure of the drive rollers is installed for each parking lot, as well as the pallet structure is simpler than the general pallets provided so far, and the manufacturing cost can be significantly reduced. .

In addition to the above advantages, it is possible to reduce the cost of the parking lot due to the high economical efficiency, ease of installation, and economical operation of the parking facilities due to the fast parking speed, and high performance and high quality of the cart and lift lift. In terms of maintainability, safety, and reliability, very excellent characteristics can be obtained as compared with the conventional one.
