Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is directed to disposing an arbitrary number of trays with traverse wheels on which a vehicle or the like is to be placed in a plurality of rows in parallel in a plane and arranging both ends on one diagonal line thereof. A dead space for one tray is formed in the section, and the trays are moved and circulated in a two-step system by the operation of respective feeders which should be arranged in the horizontal and vertical directions of the tray row. The present invention relates to a vertical tray feeding device in a plane circulation type parking device.

(Prior Art) The above-mentioned type of plane circulation parking device has already been registered as utility model registration No. 861562 (Jitsuko Sho 43-15059) "Plane circulation parking device".
In the parking device, the trays are sequentially driven in a two-step system by mutually driving the horizontal feed device and the vertical feed device with a combination of a horizontal feed fixed rail and a vertical feed moving rail. In this case, the vertical feed device has a pair of endless chains stretched on a structural frame with moving rails for placing trays arranged at equal pitches, and the circulation operation is horizontal. Either the feed or the vertical feed precedes and is alternately operated to move and circulate the tray.

(Problems to be solved by the invention) In the vertical tray feeding device for the above-mentioned plane circulation type parking device, the moving rails arranged at equal intervals in the endless chain have the same size as the traverse wheel gauge of the tray. It must be, and cannot be shortened or extended without regard to the tray wheel gauge. Therefore, since the pitch of the pair of transverse feeds and the total length of the endless chain are always multiples of the rail gauge, the total length of the vertical feed exceeds the full width of the structural frame including the pair of transverse feed devices or trays. In some cases, the entire length of the transport chain cannot be avoided.

Therefore, the plane dimension required for a parking device is such that the space on which the tray on which the automobile is placed, the rails on which the tray runs by wheels, and the structural frame are installed is the minimum. In most cases, the device does not fit in the plane size, so that there is a problem that the building 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, in the above-described tray vertical feeding device, since the starting end portion and the trailing end portion thereof project outward from the tray end edge, the utilization efficiency of the equipment installation space is poor, the structure is complicated, and the cost is high.

An object of the present invention is to shorten the total length of the vertical tray feeder to improve the utilization efficiency of the installation space and to simplify the apparatus structure to reduce the cost.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention adds a tray traverse wheel to the tray in addition to the tray traverse wheel, and operatively engages with the floor side guide during the tray traverse. A tray-side guide is provided, and the parking device has a vertical feed fixed rail laid from the dead space to the end of another tray row facing the dead space, and a vertical feed of the tray moving on the horizontal feed fixed rail. Auxiliary rollers provided at the part of the vertical feed fixed rail corresponding to the mounting position of the wheels, and a tray vertical feed that is installed and installed under the vertical feed fixed rail and drives the tray vertically along the vertical feed fixed rail. Equipment and
This tray vertical feed device includes a drive motor installed on a drive-side mount provided below a vertical feed fixed rail, a drive sprocket operatively connected to the drive motor and rotating in a horizontal plane, and a drive sprocket running vertically. Direction, a driven sprocket that is installed at a predetermined distance, an endless chain that is hung between the driving sprocket and the driven sprocket and that performs a drive circulation operation, and is attached to this endless chain, and is attached to the endless chain when the tray is vertically traversed. A pulling roller for vertically feeding the tray which is operatively engaged with the tray side guide, and the pulling roller can be circulated in the vertical direction within the range of the total length of the tray plus the gap size between the tray rows. What is done is summarized.

A vertical guide, that is, a guide groove 13, into which a tip roller (both not shown) is fitted is provided so that it can be used for both tray horizontal feed and vertical feed. Further, on the same axis of the guide groove, there is a floor side. The tray-side female guide 15 that fits into the male guide 14 and the both ends on the front side are fitted to a pair of floor-side traverse guides 16 that are used to perform tray traverse and tray longitudinal feed. Grooved sideways guide, i.e. tray side guide 17 and 18
Is provided.

In addition, an inverted L-shaped male connecting fitting 19 is provided at the front and rear portions on the left side of each tray 1, and a U-shaped female connecting fitting 20 is provided at the front and rear portions on the right side, and a coupler 21 is formed by the engagement of both connecting fittings. However, a floor guide 22 is provided between both tray rows to prevent lateral deviation when the trays are fed vertically.

Next, from the above-described configuration, the left side tray vertical feeding device 2 and the right side tray vertical feeding device 3 are connected to the tray 1 as shown in FIG.
The total distance between the tray rows and the gap distance between the tray rows, that is, the distance between the inner ends of the trays arranged in one tray row and the other tray row are added, and in this case, Since the left and right tray vertical feed devices have exactly the same structure, only the right tray vertical feed device 3 will be described. As shown in FIGS. 2 to 5, the right tray vertical feed device 3 serves as a drive motor installed on a drive-side mount 23 integrally provided under the vertical feed fixed rails 10, 10. Geared motor 24 (brake 25, motor 26, speed reducer 27), a bevel gear pair 29 directly connected to the motor via a coupling 28, a main driving sprocket 30 and a driven driving sprocket 31 drivingly connected thereto. It has upper and lower drive sprockets 32 coaxially attached to the driven sprocket, and upper and lower driven sprockets 34 on which two endless chains 33, which are cyclically driven by the same, are horizontally hung. In this case, as shown in FIGS. 3 and 4, the bevel gear pair 29 and the main driving sprocket 30 are attached to the drive shaft 36 which is pivotally provided inside the drive-side mount 23 via a pair of bearings 35. The driven sprocket 31 and the upper and lower drive sprockets 32 are mounted on the drive-side mount 23.
Mounted on another drive shaft 38 which is pivotally mounted on the outside of the sprocket 3 through a pair of bearings 37.

Further, the upper and lower driven sprockets 34 are attached to a drive shaft 42 which is pivotally provided outside a driven side mount 40 via a pair of bearings 41 as shown in FIG. 32 and the half of the total length of the two endless chains horizontally mounted on the driven sprocket 34 or in the vicinity thereof are connected by two connecting arms 43 and 44, and are erected on these arms. At the tips of the pins 45 and 46, there are attached pulling rollers 47 and 48 which are fitted to groove-shaped tray side guides 18 (17) formed at both front side corners of the back surface of the tray 1. Pins and rollers are drive sprockets 32
And tray 1 when it comes to the outermost edge of driven sprocket 34
It is set so that it is brought to a position where the gap distance between the tray rows is added to the total length of the tray. Further, chain guides 49 are provided on both sides of the drive-side frame 23 and the driven-side frame 40, and in order to prevent the slack of the two endless chains 33 and to perform smooth drive circulation, the chain guides 49 and the like are provided. Guide rollers 50 and 51 are attached to a plurality of auxiliary guide rollers (not shown) at pitches and two connecting arms 43 and 44, respectively. As is clear from the above description, the drive side mount 23, the geared motor 24, the drive side various members such as the drive sprocket 32, and the driven side mount 40 and the driven side various members such as the driven sprocket 34. The vertical feed devices 2 and 3 are housed within the entire length and width of the tray 1 almost entirely and do not protrude from the plane area (range) of the fixed rail 10, so that the plane area of the parking device can be reduced.

In FIG. 1, the tray moving circulation by the two-step method is performed by a synchronous drive circuit (not shown) of the vertical feeding devices 2, 3 and the horizontal feeding devices 4,5, and both of these feeding devices. Is a vertical drive and a horizontal feed of the tray respectively by an independent drive circuit (not shown).

(Operation) In FIG. 1, the tray 1 is moved in a two-step manner and circulated in a predetermined manner by the operations of the left and right vertical feeds 2 and 3 and the front and rear feeds 4 and 5 which are synchronously moved in opposite directions at the same time. In this case, as shown in FIG. 5 and FIG. 7, the trays 1 connected to each other by the coupler 21 are laterally fed by the operation of the rear lateral feeding device 5. At this time, the traverse wheels 9 travel on the traverse feed fixed rail 8 (the traverse wheels are free), and the tray 1 at the right end is fixed in the dead space 6. Since the groove-shaped tray-side guides 17 and 18 formed on the back surface of the tray cross over the floor-side transverse guide 16, there is no need to argue, and the longitudinal wheel 11 is an auxiliary roller. It is transferred to 12 and can be fed vertically.

Next, when the geared motor 24 of the vertical tray feeding device 3 (2) shown in FIGS. 2 to 5 is driven to rotate the main driving sprocket 30 in the hour hand direction, the driven driving sprocket is moved through the chain 39. 31 also rotates in the direction of the hour hand, so that the upper and lower drive sprockets 32 mounted coaxially with this sprocket rotate (see FIGS. 3 and 4).
2), the two endless chains 33 mounted between the upper and lower driven sprockets 34 are, as shown in FIG.
It is moved and circulated in the direction of arrow A on a horizontal plane. Along with this chain movement circulation, a pulling roller 47 (48) attached to the tip of a pin 45 (46) attached to the endless chain 33 via a connecting arm 43 (44) is formed on the back surface of the tray 1. As shown in FIGS. 6 and 7, the tray 1 is engaged with the tray-shaped guide 17 (18) and is vertically fed in the direction of arrow B with the coupler 21 removed. At the start of the vertical feeding of the tray 1, the pin 46 and the pulling roller 48 are located at the outermost end of the driven sprocket 34, that is, the position corresponding to the dead point for the movement in the vertical direction B. It starts accelerating from zero and starts accelerating gradually. Then, when the pin 46 and the pulling roller 48 move in the parallel portion of the endless chain 33, the tray 1 is transported at the same circulation speed as the endless chain 33. Then, when the pin 46 and the pulling roller 48 come into contact with the drive sprocket 32 on the opposite side, the tray 1 is gradually decelerated, and when the target position is reached, the pin 46 is moved.
Since the pulling roller 48 is located at the outermost end of the drive sprocket 32, that is, the position corresponding to the dead center for the movement in the longitudinal direction B, the moving speed of the tray 1 becomes zero.
Therefore, when the tray 1 is driven by the vertical feed, a quiet vertical feed operation is realized without being impacted by a sudden operation. And tray 1 is the first
At the same time as it is moved to the solid line position shown in the figure, the operation of the other tray vertical feed device 2 causes the tray 1 that had been in the dead space 7 until then to be vertically fed in the opposite direction and moved to the solid line position. A predetermined tray loading / unloading operation is performed by performing tray moving circulation in a two-step system by mutual operation of both feeding devices.

(Effects of the Invention) From the above, according to the present invention, in addition to the tray traverse wheels, the longitudinal wheels are provided, and the trays are vertically arranged within the range in which the gap distance between the tray rows is added to the total length of the trays. Since the tray vertical feeder having the drive sprocket that rotates in the horizontal plane for moving is installed, the height of the vertical feeder can be kept small. Further, by this vertical feeding device, the tray which has been laterally moved by the traverse wheels is transferred onto the auxiliary rollers of the longitudinal feed fixed rail at the intersection of the transverse feed fixed rail and the vertical feed fixed rail. The tray can be vertically fed. Therefore, the tray can be vertically fed by the horizontal circulating drive of the endless chain without using the moving rail by the endless chain that is circulated in the vertical direction. By shortening the overall length and reducing the total plane area of the device, the three-dimensional space efficiency can be improved and the cost can be reduced.

In addition, the vertical feeding of the tray starts from zero at the initial speed by the vertical feeding device and is accelerated, and when it reaches the arrival point next time, it is moved vertically while being decelerated so that the speed becomes zero. A quiet vertical feed operation can be realized without being impacted by a sudden operation during the feed drive.

Further, the present invention is limited to a parking device of a type in which a dead space for one tray is formed in the corner portion of a multi-row tray, and the trays can be moved and circulated in a two-step system by the operation of a horizontal feed device and a vertical feed device, or one layer Of course, it can be applied to a multi-layered parking device without being damaged.
