Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides a steel frame installed in a parking space with two upper and lower parts.
The trays arranged in parallel on the tiers are transferred in the left-right direction by the circular drive of the endless chain S, and at both ends of the tray row, the upper tray is pivoted down to the lower tier, and at the same time the lower tray is pivoted to the upper tier. (2) This relates to a circular circulation parking device that is raised.

(Prior Art) As a circular circulation type parking system of the above-mentioned type, a stratified parking system has been proposed, for example, in Japanese Patent Publication No. 45-13613.
5. The device consists of a chain lever arranged in a row at appropriate intervals on a two-ring moving endless chain lever, a barre 71 whose one end is pivoted to the chain lever, and a barre 71 mounted on the other end of the pallet. a guide rail provided along the endless chain to engage with and guide the guide roller, and a guide rail provided to allow the balent shaft to pass through the curved portion of the guide rail; The apparatus includes an opening/closing means and a rotation support means for horizontally rotating the pallet while supporting the guide rollers when the pallet passes through the curved portion of the guide rail.

In addition, there are other facilities for storage and storage of cargo such as automobiles, etc. ! ! "Transportation Device", Utility Model Publication No. 45-2874
3 r Two-tier parking device J and Jitsugyo Kosho 46-1954 r
Parking devices j and the like have also been proposed and are publicly known.

(Problems to be Solved by the Invention) In all of the above-mentioned circular circulation parking devices, the lateral feeding speed of the pallet or container rows is the same, and the feeding speed of the pallets or containers at the turning parts at both ends of one row is If the cross-feeding speed of the balent or container is the same, the loaded vehicle will interfere with or come into contact with the preceding loaded vehicle, so the circumferential speed at the turning section must be faster than the cross-feeding speed.
In reality, for example, when a balent or a container moves at a constant velocity of 12 m/min, it must rotate once, so the circumferential speed of the rotating section is approximately three times as high as 34 m/min.

Therefore, in each of the above-mentioned parking devices, a horizontal rotation support means, a parallelogram link means, or a mechanical conversion device is installed in the revolving part in order to accelerate the feeding speed of the pallet or container in the revolving part. The structure is complicated and the cost is high, and if the center of the leading (trailing) pallet or container does not reach the center of the driving wheel (driven wheel), the next pallet or container will be placed at the starting end (terminal end) of the rotating section. position)
Driving becomes intermittent because it doesn't reach .

There are difficulties in implementing high-speed specifications, and the disadvantage is that it takes time for one person to leave the warehouse.

In addition, since the support of the balent or container is unstable, there is a risk of it falling off when turning and causing various troubles.
In order to increase the traversal speed (circulation speed) in order to shorten the time taken for people to leave the warehouse, the circumferential speed of the above-mentioned rotating section becomes in direct proportion and becomes unintentionally high, making it uneconomical to increase the IJ force. Next door.

In history, the number of barrels in the swing section was 1-
Another disadvantage is that the entire device becomes longer due to the outward protrusion of the container, which reduces the efficiency of use of the upper surface.

The object of the present invention is to provide a circular circulation parking system that has good space utilization efficiency and can operate at high speed continuously to shorten the time taken for vehicles to enter and exit the parking lot, thereby reducing noise, and by simplifying the structure and reducing costs. It is about providing.

Next, a pair of plummer bearings 27 are provided on both sides of the bearing frame 26 which is bridged inside and above the drive part frame 1. Synchronous coupling shaft 30 with driven sprocket 29
is pivotally installed, and the driven sprocket 29 on the motor 18 side
A drive chain 32 is installed between the drive sprocket 31 attached to the intermediate shaft 20 of the reduction gear [21],
When the engine is operated, the driven sprocket 23 attached to the output shaft 19 of the $i speed machine 21 rotates, and the double drive chain 2
Power is transmitted to the main driving sprocket 16 via 4,
The main drive wheel 14 integrated with the sprocket performs appropriate rotational movement, and at the same time the drive sprocket 1-31 attached to the intermediate shaft 20 of the reducer 21 rotates, and the power is synchronized via the drive chain 32 and the driven sprocket 29. The signal is transmitted to the connecting shaft 30, and is input to the main drive wheel (both not shown) through the drive sprocket, slave drive sprocket, and main drive sprocket of the reducer on the opposite side having the same number of teeth. The driving main wheels 14 are operated synchronously.

Note that the power transmission system installed on the drive section frame 1 on the opposite side of the two is exactly the same as the power transmission system except for the electric motor 18 on the drive side, and only the mounting directions thereof are opposite to each other.

Furthermore, as shown in FIG.
A driven main wheel 35 is rotatably mounted on each of the support shafts 34 attached to the main wheels 3, and the power transmission system for these two main wheels has a power transmission system other than the electric motor 18 on the driving side and the synchronous connecting shaft 3°. The explanation will be omitted since it is exactly the same except that it is installed opposite to the transmission system.

Next, between the driving main wheel 14 and the driven main wheel 35 is a jll (Seiaki link chain 3) guided by the upper chain guide 6 and the lower chain guide 7.
6 is mounted on the link chain, and the same number of attachment-link plates 37 as the number of cars accommodated are attached at equal pitches to the link chain, and a pair of flanged chains are attached to both ends of the base of these attachment link plates. Rollers 38 (4 rollers in total) are installed on the attachment link plates 37 on the front and back or on both sides.At the free end of the attachment link plate, there is a reamer bolt (see figure) for rotatably supporting a loading tray, which will be described later. A metal bearing (head block) 39 is installed that can be divided into two parts by removing the head block (not shown).

In addition, as shown in FIGS. 1, 3, 4, and 5, the loading trays 40 on which automobiles are placed, which are arranged in two rows (upper and lower), have an upper tray 41 and an opening with a smaller width than the upper tray 41. It is formed integrally with the letter-shaped lower tray hend 42 via knock pins (not shown), and is constructed so that it can be separated or assembled, and a pair of supporting shafts are provided at the central portions of both sides in the longitudinal direction of the lower tray hend. 43 are mounted opposite to each other, and these supporting shafts are pivotally supported by metal bearings or hend blocks 39 mounted on the free ends of the attachment link plates 37, whereby the loading trays 4
It is constructed so that it can support a load from zero load to no load and is rotatable. Furthermore, a plate 45 having two guide rollers 44 at its tips is rotatably attached to the free end of the five-sided support shaft 43, and a three-point support system between these guide rollers and the support shaft is provided. Loading tray 4
0 is always held horizontally when driving or turning, and a keystone plate ( (not shown) is under tension.

Next, tensioning devices 4 for the drive link chain 36, which mainly consist of a pressing bolt 46 and a coil spring 47, are provided oppositely below the intermediate frame 2 and the driven frame 3, thereby tightening both frames. The coil spring is tensioned by a strong compressive force to constantly absorb the expansion and contraction that occurs when the chain is driven and rotated.

Furthermore, the circular circulation parking device according to the present invention has a second
As shown in the figure, a forklift 49 that is buried in the ground F and that lifts and lowers the upper tray 41 of the loading tray 40 is installed on the side of the drive frame l. A pair of lift columns 51 and a drive roller chain 52, which are arranged opposite to the frame 50, and a drive sprocket 53 and a driven sprocket 54, etc., installed at the lower and upper parts of the lift column on which the chains are mounted. The elevating frame 50 is raised or lowered by rotation of the drive sprocket driven by a drive device (not shown) as appropriate.

(Function) The circular circulation parking device according to the present invention operates in the upper and lower stages of the intermediate frame 2! 12 The transverse feeding of the load tray 40 in the left-right direction and the rotational feeding from the upper stage to the lower stage in the driving part frame l and the driven part frame 3 or vice versa are performed smoothly and continuously by the drive of the brake-equipped prime mover 18. . That is, as shown in FIG. 3, when the prime mover 18 with brake is started, the reducer 21 is driven via the gear coupling 22, and the output shaft 19 of the reducer is driven.
The driven sprocket 23 rotates, and the double drive chain 24 attached to the sprocket rotates the main drive sprocket 16 in the counter-hour direction (or in the hour hand direction).
a main driving wheel 1 which rotates to
4 also rotates in the same direction. On the other hand, the rotation of the drive sprocket 31 attached to the intermediate shaft 20 of the 2-speed reducer 21 causes the driven sprocket 29 to rotate via the drive chain 32, and the synchronous connecting shaft 30 integrated with the sprocket to rotate. The driving main wheel on the opposite side rotates synchronously using a completely similar drive mechanism except for the prime mover with a brake in the drive mechanism of the main driving wheel 14.

Therefore, the driving main wheel 14 and the driven main wheel 35
The drive link chain 36, which is endlessly mounted on the drive wheel, moves leftward (or rightward) by eight rotations of the drive wheel in the counter-hour direction (or in the hour hand direction);
Attachment link plate 37 to the link chain
The loading tray 40 attached via the tray is traversed to the left (or right).

Therefore, when storing a car, as shown in FIG. A is held in a horizontal position by a three-point support system (isosceles triangle with this support axis as the apex) of two horizontal holding guide rollers 44 and a support shaft 43 that pivotally supports the vertical attachment link plate 37. When the lateral feed continues from this state, the guide rollers pass through the semicircular outer guide rail 8 and the arcuate inner guide rail 10, respectively, and at the same time, the attachment link plate turns 90 degrees to the left. The loading tray 40 is continuously circulated until it reaches the A' position, that is, the hoistway position (lift installation part), and is then stopped.

Note that the loaded tray 40 that has been called out has its rotation direction determined by an appropriate sorting device (not shown), and is operated so as to arrive at the lift section (position A') through the closest route.

Next, when the elevating frame 50 of the forklift 49, which had been at the lowest stage, is raised by the operation of the lift, the elevating frame forms a loading tray, and the upper tray 41, which is wider than the U-shaped tray bed 42, forms a loading tray. The material is scooped up, reaches the solid line position shown in FIG. Next, when a car gets on the upper tray 41 on the elevating frame 50, the forklift 49 is operated to lower the elevating frame and transfer the upper tray to the lower tray head 42 waiting at the solid line position of the turning section. After that, the elevating frame descends to the lowest stage. Subsequently, the loading tray 40 on the A' side with the car loaded thereon is rotated to the upper (or lower) stage through the route closer to the warehousing location, and then transversely fed to the right to be warehoved at a predetermined position. However, in this case, as described above, the horizontal holding of the loading tray 40 at the rotating portion is achieved by the guide rollers 44 fitting and sliding into the semicircular outer guide rail 8 and the arcuate inner guide rail 10, respectively. This is brought about by supporting and shifting the eccentric load while acting alternately due to the correlation with the supporting shaft 43 of the U-shaped lower tray bend 42 at each point where each guide roller is displaced. loading tray 4 in
By the zero half rotation, the subsequent loading tray 40 is traversed by one inch and becomes in a standby state for loading and unloading automobiles.

(Effects) Since the present invention is configured as described above, it can produce the effects described below.

(1) Although the feeding speed of the loaded tray in the revolving section is slightly increased compared to the lateral feeding speed, it is less than half that of conventional equipment, and is achieved by stable continuous high-speed operation, shortening loading and unloading time, and downsizing of power. It is possible to improve economic efficiency and reduce noise.

(2) Unlike conventional devices, the structure is simple and has a low failure rate because there are no horizontal rotation support means, two parallelogram link means, or a mechanical conversion device to increase the speed in the swing section. The length of the entire device is shortened, and the efficiency of land and space use is high, with emphasis on space saving.

(3) The loading tray is attached to the supporting shaft of the lower tray hend and the end of the supporting shaft.
Since the three-point support system using the guide rollers allows the machine to maintain a horizontal state at all times even when traveling or turning, there is no chance of the load tray falling off and there is no risk of any trouble occurring.

(4) The flanged chain roller attached to the drive link chain reciprocates on the upper and lower guide rails, which have channels facing each other in cross section.
3! Since it is possible to keep the load tray parallel to the longitudinal position regulation, i? 1. It is possible to travel while suppressing overturning or tilting of the lei.
