Description

[Detailed Description of the Invention] Conventionally, a plurality of pallets for loading onto vehicles are arranged on a transfer path consisting of two vertical and horizontal rows arranged in a rectangular shape so that two opposite corners are empty spaces when stopped. Examples of horizontal circulation parking equipment that alternately moves and circulates one pitch are, for example, the Special Publication Publication No. 45-32568 and the Special Publication Publication No. 45-3.
There are devices such as those shown in Publication No. 8445, etc., and in these devices, a moving rail is fixed on a conveyor that circulates on a vertical transfer path so as to be an extension of a horizontal transfer rail, and the moving rail is The pallets are mounted on rails via fixed wheels for lateral transfer and are moved.

The vertical transfer conveyor in this case requires a chain whose total length is four times the normal transfer pitch in order to perform circulation drive.

In order to accommodate the entire conveyor, even if the sprocket diameter is increased somewhat, the length of the vertical transfer path must be parallel.
It will be longer and protrude significantly from both outside sides of the two lateral transfer paths.

Furthermore, increasing the diameter of the sprocket means making the pit deeper, which not only increases the cost of the foundation work required for the bit, but also inevitably reduces parking efficiency due to the large area occupied by the vertical transfer path.

In addition, as shown in Japanese Patent Publication No. 42-15251, a horizontal transfer rail is extended on the vertical transfer path, and a large number of wheels are arranged in two rows perpendicular to the extended horizontal transfer rail. In addition, a vertical transport wheel train that can be raised and lowered is provided,
On the other hand, on each pallet side, two rows of vertical transfer rails that can be engaged with the vertical transfer wheels are fixed together with traverse wheels, and the pallets transferred onto the vertical transfer path are transported by the upper load of the vertical transfer wheels. There is a system in which the vertical transport wheels are rotated by an appropriate drive means after being made independent of the traversing rails, thereby vertically transporting the pallet.

In this case, each pallet must be provided with vertical transport rails in addition to traversing wheels, and an additional lifting device for the vertical transport wheel train must be provided, so the cost is quite high. Moreover, since the vertical wheel train needs time to move up or down between the horizontal and vertical movement operations, there is a drawback that the time required for entering and exiting the warehouse becomes longer.

In view of the above-mentioned circumstances, the present invention arranges an extension rail on a vertical transfer path with a slight gap from the end of the transverse rail, and provides a set of four longitudinal transfer rails capable of filling the gap so as to be movable back and forth. While the pallet supported on the four vertically moving rails has moved slightly in the direction of the horizontally moving rails, the vertically moving rails move at high speed toward the gap on both sides of the extension rail at the opposite position, and the pallet moves horizontally. The pallet is conveyed vertically by supporting the pallet sent from the horizontal transfer path in line with the rail, and when the wheels provided on the pallet pass through the gap, the wheels provided on the pallet This relates to a flat circulation type parking facility characterized in that a pallet is supported by engagement between an auxiliary rail and a support wheel provided near the end of the transverse rail. By reciprocating the row movement rail, the structure of the vertical transfer device is made smaller and simpler, thereby providing a flat circulation parking facility that is efficient in parking without delaying pallet circulation time and is inexpensive in equipment cost. This is the purpose.

To explain in detail based on the embodiment shown in the figure, 1.1' and 2.

Reference numerals 4, 4', 5, and 5' designate extension rails fixedly disposed within the vertical transfer paths 2, 2' on the extension lines of both ends of the transverse rails 3, 3', respectively, at appropriate intervals from the ends of the transverse rails.

6 is a pallet for mounting on a vehicle, with both vertical transfer paths 2 and 2 diagonally arranged.
If there is an empty space in the ' section, one piece per each row should be connected and arranged on the horizontal transfer path 1.
8, so that they can be connected to each other, and four flanged wheels 10 are provided on the back surface so as to engage with the pin racks 9 at appropriate pitches and the traverse rails 3 and 3' to enable integral lateral movement of the pallet. Furthermore, auxiliary rails 11 of an appropriate length are vertically provided on both outer sides of the pin rack 90.

Reference numeral 12 denotes a forward/reverse motor for traversing drive, which includes a reduction gear 13, a rotating shaft 14, and a wheel 1 that meshes with the pin rack 9.
The pallet 6 is moved across the pallet 6 through the pallet 5.

16 and 16' are longitudinal moving rails, and near both ends there are transverse rails 3 and 3, 3' and 3' and short rails 17 and 17 at equal intervals.
17' and 17' are formed to protrude upward, and a set of two of each extension rail 4, 4', 5, 5' is moved onto the vertical transfer path 2, 2' while maintaining a spacing slightly wider than the length of the extension rails 4, 4', 5, 5'. It is arranged so that it can reciprocate between positions that are in line with the transverse rails 3, 3 or 3', 3'.

The short rails 17 and 17' are the transverse rail 3 and the extension rails 4 and 5, or the transverse rail 3' and the extension rails 4' and 5.
The length shall be sufficient to fill the gap between

18, 19 and 18', 19' are longitudinal movement rails 16
and 16' drive chain, both ends of which are fixed to both ends of the longitudinal transfer rail 16 or 16', and the longitudinal transfer path 2
・2' each fixed at appropriate intervals on both ends of
Through the sprocket 21 or 22 which is pivotally supported between the channels 20 and 20 for each individual, and the second stage sprocket 23, it is stretched by the second stage sprockets 24 and 25 arranged between the lateral transfer paths 1 and 1', and the second stage sprocket 25 is connected to a transmission-equipped reversible common drive source consisting of a transmission 26 and a forward/reverse rotation motor 27, and is arranged so that the longitudinal movement rail 16 or 16' is reciprocated by the drive of the motor 27.

The transmission 26 has two speeds, high and low, and is on the low speed side when moving with the pallet 6 on the longitudinal movement rails 16 and 16'. - When the 16' moves in an empty state, it receives an appropriate signal and switches to the high speed side.

28 is the vertical movement rail 16 on the vertical movement path 2, 2'.
・A guide member erected along both sides of the moving path of 16', each with a guide rail 29 protruding from the side, and a dog/small dog that is pivotally supported on both sides of the vertical moving rails 16 and 16' in two stages, upper and lower. It engages with four guide rollers 30, 31 to guide the longitudinal movement rails 16, 16' during reciprocating movement.

Furthermore, the guide member 28 is located at both ends of the transverse rails 3 and 3'. It also serves as a support member at both ends of the extension rails 4, 4', 5, 5'.

Reference numeral 32 denotes support wheels protruding outward from the sides near both ends of each of the transverse rails 3 and 3', and the pallet 6 supports the gap between the transverse rails 3 or 3' and the extension rails 4 and 5 or 4' and 5'. The pallet 6 is arranged so that it can engage with the auxiliary rail 11 and support one end of the pallet 6 when passing over the pallet.

In addition, if the short rails 17 and 17' are formed with a slight groove in the center or a curved surface with a recess in the center, the wheels can be easily used when the pallet 6 is mounted and moved. 10
It can be used to prevent the product from coming off.

Next, the effect will be explained.

The horizontal and vertical transfer of the pallet 6 is carried out in such a manner that the vertical and horizontal transfer rows, which are often intersecting with each other and are opposed to each other, are simultaneously moved in opposite directions.

The pallet 6 is laterally transferred by rotating the wheel 150, which is driven by the drive unit 1 of the motor 12 and engages with the pin rack 9 via the speed reducer 13.

The vertical movement is driven by the motor 27, and the longitudinal movement rail is moved by the chains 18, 19 or 18', 19' via the transmission 26, second stage sprockets 25, 24, 23 and second stage sprocket 22 or sprocket 21. 16.1
By moving the pallet 6 or 16' and 16', the pallet 60 mounted on the short rail 17 or 17' of the moving rail via the wheels 10 is transferred at a low speed to the opposite position side.

In this case, the guide rollers 30 and 31 are connected to the guide rail 29.
The upper and lower surfaces roll in a supporting manner to provide guidance during vertical movement.
In addition, the connection between the pallets 6 and 6 is made using fishing-shaped connecting fittings 7 and 8.
Since it is free in the vertical transport direction, the connection is automatically released.

FIG. 5 is an enlarged detailed view of the pallet state at the right end of the lower row in FIG. 1, viewed from the front, and FIGS. 7 A-E show that the right end pallet 6 in FIG. ) shows the counterclockwise horizontal transfer state after being vertically transferred to the vertical transfer rail 16'.
It also shows a state in which the pallet 16' returns to the lower row by high-speed movement and a lower row pallet 6 newly transferred into the vertical transfer path 2' is loaded thereon.

In addition, FIG. 6 shows an extension rail 5 from the transverse rail 3' of the lower row pallet 6 in an intermediate state between B and C in FIG.
′.

In FIG. 7A, counterclockwise lateral transfer is started as shown by the arrow, and in FIG. 10 has been transferred onto the extension rail 5, and the front wheel 10 of the first (right end) pallet 6 in the lower row is still on the transverse rail 3'l.

From this state, the vertical movement rails 16', 16' begin to return at high speed to the lower row side.

Then, as the pallet further advances, the front wheel 10 of the lower leading pallet 6 reaches the gap between the transverse rail 3' and the extension rail 5', as shown in FIG. The front wheels 10 are engaged with the support wheels 32 of the pallet to support the entire pallet, thereby allowing the front wheels 10 to be safely transferred to the extension rail 5', resulting in the state shown in FIG. 7C.

At this time, the vertical movement rails 16' and 16' have returned to the intermediate position between the upper and lower rows.

Further, in the state shown in FIG. 7D, the rear wheels 10 of the upper row rear pallet 6 have already been transferred onto the transverse rail 3, but when the wheels 10 pass through the gap between the transverse rail 3 and the extension rail 5, The auxiliary rail 11 and the support wheels 3 are also connected in exactly the same manner as the front wheels of the lower leading pallet 6 in FIG.
The rear part of the pallet is supported by the engagement of the parts 2 and 2.

Further, the longitudinal movement rails 16', 16' have completed their return and are now in a straight line with the transverse rail 3'.

Therefore, as shown in FIG. 7E, the lower leading pallet 6 moves further to the right and the vertically moving rail 16' has completed its return.
・Move onto 16' and stop.

Further, the upper row rear pallets 6 advance to a position where they do not interfere with the next vertical transfer and stop at the same time.

Vertical/horizontal transfer and reverse circulation movement on the vertical transfer path 2 side are also performed in the same manner as described above.

As detailed above, according to the present invention, the vertical movement rail as a vertical transfer device returns to its original position at a higher speed than when the pallet is moved slightly toward the transverse rail after the pallet is transferred at a low speed. supports the pallet moving into the next vertical transfer path, and during this time, when the pallet passes through the gap between the transverse rail and the extension rail, the front of the pallet or Since the rear part is supported, it can be used as a small and simple transportation means that only moves back and forth, and therefore can be used as a flat circulation parking facility with low equipment cost and high parking efficiency without delaying the circulation time. It's something you get.
