Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides a method for arranging an arbitrary number of trays with transverse wheels on which vehicles, etc. are to be placed in a plurality of rows in parallel, and placing each tray at the upper end position of one diagonal line. A horizontal circulation parking device that forms a dead space for one vehicle and is configured to move and circulate the tray in a two-step system by operating respective feeding devices that are arranged oppositely in the vertical and horizontal directions. This is related.

(Prior Art) The above-mentioned type of horizontal circulation parking device has already been disclosed and publicly known as Utility Model Registration No. 861562 (Utility Model Publication No. 15059, 1973) as “Flat Circulation Parking Device”.
In this parking device, the trays are sequentially moved and circulated in a two-step system by alternately driving the horizontal feeding device and the vertical feeding device using a combination of a horizontal feeding fixed rail and a vertical feeding fixed rail.
In this case, the vertical feeding device has moving rails on which the trays are placed between a pair of endless chains stretched over the structural frame, which are arranged at equal pitches, and the circulation operation can be performed either horizontally or vertically. The trays are configured to operate in advance and alternately to circulate the tray.

(Problem to be Solved by the Invention) In the tray vertical feeding device of the horizontal circulation type parking device as described above, the moving rails arranged at equal intervals in the endless chain have the same dimensions corresponding to the traverse wheel gauge of the tray. It must be possible to shorten or extend the tray by ignoring its wheel gauge. Therefore, since the pitch of the pair of horizontal feeders and the total length of the endless chain are always multiples of the rail gauge, the total length of the pair of horizontal feeders or the vertical feeder exceeds the entire width of the structural frame including the tray. , there are cases where this must be the entire length of the vertical feed chain.

Therefore, the planar dimensions required for a parking device are as follows: The tray on which the car is placed needs only the rails on which the tray runs on its wheels and the minimum space for the structural frame to be installed. In most cases, the planar dimensions cannot be accommodated, so there is a problem in that the architectural space at the time of planning must be set to a size that can cover the entire length of the vertical feeding device. For example, the above-mentioned vertical feeding device has a starting end and a distal end projecting outward from the edge of the tray, so that the equipment installation space is inefficiently used, and the structure is complicated and the cost is high.

(Means for solving the problem) Therefore, according to the present invention, a tray longitudinal wheel is added to the tray in addition to the tray transverse wheel, and a transverse feed fixed rail on which the transverse wheel runs and the longitudinal wheel A level difference is provided between the tray and the vertical feed fixed rail on which the tray runs, so that the tray can be smoothly fed from horizontal to vertical or vice versa.

(Example) In Fig. 1, 1 is a tray on which a car or the like is placed or is moved and circulated without placing it thereon, 2 is a tray left side vertical feeding device, 3 is a tray right side vertical feeding device, and 4 is a tray. Reference numeral 5 indicates a front cross-feeding device and a tray rear cross-feeding device, in which the trays 1 are arranged in two rows in parallel and adjacent to each other in any number of planes, and the upper end position of one diagonal line is Dead space for one tray 6,
7 is formed, and on the back side of the tray 1 there is a pair of opposing arrangement (4 in total) running on the transverse feed fixed rail 8.
transverse wheels 9) and a pair (total of 4) of vertical wheels 11 running on vertical feed fixed rails 10, arranged oppositely.
is installed. Further, as shown in FIG. 2, near the inner side of the vertical feed fixed rail where the horizontal feed fixed rail 8 and the longitudinal feed fixed rail 10 intersect, a longitudinal wheel 11 is mounted on a supporting member such as an auxiliary roller 12 on which the vertical feed fixed rail 10 is mounted. are installed, and a horizontal feed guide 1 is installed on the horizontal feed fixed rail 8 and the vertical feed fixed rail 10.
3 and a longitudinal feed guide 14 are provided to prevent the transverse wheels 9 and the longitudinal wheels 11 from coming off the rails while running on the rails.

Furthermore, the trays 1 that have been traversed on the traverse fixed rails 8 by the traversing wheels 9 are transferred by the longitudinal wheels 11 onto auxiliary rollers 12 provided on the longitudinal fixed rails 10 during vertical feeding. but,
In order to carry out this roller transfer smoothly and without any trouble, slopes 15 and 16 are formed at the rail intersections, respectively, as shown in FIGS. is set to be slightly (several mm) higher than the level of the transverse feed fixed rail. Therefore, when the tray 1 shifts from horizontal feeding to vertical feeding, the traversing wheels 9 float or separate from the surface of the horizontal feeding fixed rail 8, and naturally the auxiliary roller 12 also moves to the level of the vertical feeding fixed rail 10. It's becoming the same.

Next, since the tray left vertical feeding device 2 and the tray right vertical feeding device 3 have completely similar structures, only the right side will be explained. A driving sprocket 19 having a rotating shaft on which a bevel gear that meshes with an attached bevel gear (not shown) is attached, a driven sprocket 19' having a rotating shaft provided opposite to this, and a chain hooked on these. 18, a vertical feed drive sprocket 21 ₁ is attached to the rotating shaft of the driven sprocket 19', and a driven sprocket 21 ₂ is provided at a position opposite thereto, and an endless chain 20 is attached to these sprockets. In this case, the vertical feed drive sprocket pair is installed corresponding to the necessary stroke to vertically feed the tray 1 from the front tray row to the rear tray row, and the two upper and lower endless chains 20 are Two pins 22 corresponding to the vertical feed pitch are installed to bridge the upper chain and the lower chain to prevent pin runout. It engages with groove-shaped latches 23 and 24.

(Function) In FIG. 1, the tray is moved and circulated in a two-step manner by the operation of the left and right vertical feed devices 2, 3 and the front and rear cross feed devices 4, 5, which are moved simultaneously in opposite directions in synchronization. In this case, as shown in FIG. 3 and FIG. The transverse wheels 9 run on the auxiliary rollers 12 (the longitudinal wheels 11 are free), and then the longitudinal wheels 11 are smoothly transferred onto the auxiliary rollers 12 without any hindrance, allowing vertical feeding. becomes.

That is, the trays 1 connected at the coupler 25 are individually moved laterally by the running of the traversing wheels 9 on the traversing fixed rail 8 by the operation of the front traversing device 4, and the traversing wheels 9 of the preceding tray 1 are At the same time as it climbs the slopes 15 and 16 provided on the transverse feed fixed rail, the longitudinal wheel 11 lifts up, rides on the auxiliary roller 12 and stops, and the transverse wheel 9 rises slightly away from the transverse feed fixed rail surface. Therefore,
When the tray 1 is fed vertically, it can be moved vertically without contacting the rail surface.

In addition, there are parts where the horizontal feed fixed rail 8 and the vertical feed fixed rail 10 intersect, where the horizontal feed guide 13 and the vertical feed guide 14 are not provided, but this is to prevent the traveling tray 1 from becoming free. When vertically feeding, the cutter 25 of the adjacent tray 1
The mutual engagement of the coupler pullers 25 of the tray 1 in the vertical feed section is followed by the length of the coupler, and during horizontal feed, the longitudinal direction of the vertical feed guide 14 provided on the tray side during vertical feed is followed. It's becoming more and more difficult to get free.

Next, the traversing device 4 shown in FIG.
5 and the vertical feed device 3 driven in synchronization with each other, the endless chains 20 rotate in a horizontal plane, and the pins 22 attached to these chains engage with the latches 23 provided on the back surface of the tray. Tray 1
is removed from the coupler 25 and moved to the dead space 6 position, and at the same time it is moved to the other vertical feeding device 2.
It is moved to the dead space 7 at , and the two-step vertical feeding is completed.

In the embodiment described above, when the tray 1 shifts from horizontal feeding to vertical feeding, slopes 15 and 16 are provided on the horizontal feeding fixed rail 8 to change the level of the vertical feeding fixed rail 10 to the horizontal feeding. Although the case where the level is slightly higher than that of the fixed rail has been described, in order to achieve the same purpose, it is possible to provide a slope on the vertical feeding fixed rail and a supporting member such as an auxiliary roller on the horizontal feeding fixed rail. Therefore, the level of the horizontal feed fixed rail may be slightly higher than the level of the vertical feed fixed rail. It is also possible to use a swinging restoring arm with a spring-loaded arcuate surface instead of the auxiliary roller as the carrier member.

(Effects of the Invention) As described above, according to the present invention, a vertical wheel is provided in addition to a tray horizontal wheel, a level difference is created between a vertical feeding fixed rail and a horizontal feeding fixed rail, and a high level is achieved. Since a supporting member on which the longitudinal wheels (or transverse wheels) are mounted is provided on the rail, the tray that has been traveling transversely on the transverse wheels can be transferred to the longitudinal fixed rail by the longitudinal wheels at the intersection of both rails. Therefore, since it is possible to vertically feed the tray without using a moving rail system using an endless chain, the total length of the tray vertical feeding device can be shortened and the total flat area of the device can be increased. By reducing the size, space can be used efficiently and costs can be reduced.

Further, the present invention is further limited to a parking device of the type that forms a dead space for one tray at the corner of a plurality of tray rows and moves and circulates the tray in a four-step system by operating a horizontal and vertical feeding device. Of course, it can also be applied to a multi-layered parking device without any problems.
