Reference numeral 29 denotes a geared motor with a brake capable of forward and reverse movement for reciprocating the longitudinal carriages 24 and 24', and connects a directly coupled shaft 30 supported by the guide rail 27 to the longitudinal transfer path 2.
The shaft 2' is rotatably disposed at one outer end of the shaft 2', and rotation is transmitted by gears 31 to a transmission shaft 32 which is also supported on the guide rail 27 in parallel with the direct connection shaft 30.

Reference numeral 33 denotes a fixed shaft fixed to the guide rail 27 at the outer end of the vertical transfer path 2, 2' facing the direct connection shaft 30 and the transmission shaft 32.

34 is a sprocket provided on each of the direct coupling shaft 30 and the transmission shaft 32 so as to rotate together, and 35 is four sprockets rotatably provided on the fixed shaft 33.

Reference numerals 36 and 37 are drive chains 7 for the longitudinal carriages 24 and 24', which are fixed at both ends via sprockets 34 and 35, respectively, to short rails 26 provided at both ends of one longitudinal carriage 24 or 24'. By rotating the gear motor 29 in the forward and reverse directions, the longitudinal carriages 24, 24 and 24', 24' for one set are reciprocated in opposite directions.

38, 38', 39, 39' are groove-shaped guide rails that open upward on the floor surface of the central part of the vertical transfer paths 2, 2' in the extensions of both ends of the horizontal transfer paths 1, 1'; The groove-shaped guide rails 38 and 38' and the intermediate guide rails 39 and 39' are opened upwardly and fixed on the floor in the same row with a space of an appropriate length between them, and the pallets 10 and 11 are connected to the pallets 10 and 11, respectively.

This makes it possible to perform auxiliary guidance during linear movement of 0 or 11.

50 is a fork-shaped lift that doubles as a rail for loading and unloading provided in the hoistway 3, 51 and 52 are lift guide rails and balance weight guide rails, 53 is a forward/reverse mode with brake for lifting the lift, and 54 is a balance weight. It is.

The movement of the pallet between the vertical transfer path 2 on the side of the hoistway 3 and the lift 50 is carried out by independent operation of the lateral movement mode 21 on the side of the lateral transfer path 1'. The attached rollers 56 cooperate with each other.

In addition, the grooved guide rail L/38, 38', 39,
As shown in FIG. 14, 39' has a bent part near the middle part and is shifted by a dimension e, and the connecting female metal fittings 12 and
15 and the dimensions of each part of the connecting male fittings 13 and 14 w12w
22w3. e is slightly smaller than W2, and W
1" W3 + 28, and the pallets 10 and 11 are slightly meandered during vertical transport to prevent collisions between the connecting fittings (15th to
Figure 17).

Also, the distance 11 between the transverse wheel 18 and the outer end of the bracket 17 is
and transverse rails 7, 7' or extension rails 8, 8',
The relationship between the flanged rollers 19 provided at 9 and 9' and the distance 12 (an example is shown in Fig. 20) between the ends of the short rails 26 (the same applies to the bracket 17' side) is 11>12. As illustrated in FIG. 21, when the pallet 10 moves in the direction of the arrow from the position shown in FIG. This is to prevent the pallet 10 from falling.

Furthermore, the inner end of the bracket 17 (the same goes for the bracket 17' side) is slightly extended as shown in FIGS.
By providing an arcuate notch 17a that is slightly longer than the diameter of the flanged roller 14 in the normal vertical movement position, the collision with the flanged roller 19 during vertical movement of the pallet is avoided, and the transverse wheel 18 is When there is no short rail 26 below, the pallet 10 is supported by the engagement of the notch 17a and the flanged roller 19.
Or, it is like preventing the 11th spatial infiltration.

57 is an auxiliary parking space provided beside the vertical transfer path 2 on the extension of the horizontal transfer path 1, and a crossing rail 59 with flanged rollers 58 is located on the extension of the transverse rails 7, 7 and extension rails 8, 8. Two auxiliary parking rails 60 are arranged through the parking lot.

The rail 60 is pivoted around the center by a bracket 61 as appropriate, and the vertical transfer path 2 side can be slightly raised by extension of the cylinder 62 with an auxiliary parking pallet 10' having exactly the same configuration as the pallet 10 mounted thereon. 63 is a stopper that prevents the pallet 10' from moving during the ascent, and is engaged with the traversing wheels 18 to prevent the pallet 10' from moving.
It is designed to ensure a predetermined stopping position.

Note that when the auxiliary parking pallet 10' is placed on the auxiliary parking rails 60, 60 and the rails are raised and lowered, - the pallet 10 (auxiliary parking Only the longitudinal carriage 24 is capable of vertically transporting the pallet 10' between the auxiliary parking space 57 and the lift 50, so that it can be connected to the auxiliary parking pallet 10' when it is on the auxiliary parking space 57. The connecting fittings 12 to 15 between the pallet 10 and the pallet 10 can be automatically engaged and disengaged. It is enough that it can be solved.

Therefore, when the pallets 10 and 11 are circulated on the horizontal transfer path 11' and the vertical transfer path 2 and 2' (at this time, there are no pallets on the lift 50, and there are no auxiliary parking pallets on the auxiliary parking space 57). 10' is in an inclined upward state), and the horizontal transfer modes 21 and 2 are arranged so that one empty space is created in each of the vertical transfer paths 2 and 2'.
Simultaneous opposing transfer by 1 and vertical transfer modes 29, 29
Simultaneous counter-transfer for one pallet is carried out alternately, and when loading or unloading pallets 10 or 11, only the lateral transfer mode 21 on the lateral transfer path 1' side is driven independently, and the auxiliary parking pallet 10 The structure is such that the loading and unloading of the paper is carried out by independently driving both of the transfer modes 21 and the vertical transfer mode 29 on the vertical transfer path 2 side.

First, let's talk about horizontal transfer.

In the stopped state, the roller 16 is always connected to the screws 20 and 20'.
The roller 16 is engaged with the screw at the center of the roller 16, and when the lateral transfer motor 21 is started, the roller 16 is gradually moved.
/2 pallet pitch movement reaches one end of the screw.

At this time, the roller 16 of the succeeding pallet is
20', and further movement of the V2 pallet pitch causes the trailing roller 16 to reach the center of the screw, secure the correct position, and stop.

During the movement, each pallet 10, 11 is guided by the engagement between the traversing wheels 18 and the traversing rails 7, 7'.

During the horizontal transfer, the horizontal transfer paths 1 and 1' and the vertical transfer paths 2 and
Typically, the 20th pallet is moved between 2'
This will be explained with reference to FIG.

In other words, FIG. 20 also shows the state before the pallet 10 is moved from the vertical transfer path 2' to the horizontal transfer path 1, with the short rail 26 of the vertical carriage 24 located adjacent to the left end of the extension rail 9, A gap is formed between the transverse rail 7 and the transverse rail 7.

When the pallet 10 moves to the left as shown by the arrow and the traverse wheel 18 reaches the left end of the short rail 26 as shown in FIG. 21, the left end of the bracket 17 is supported by the flanged roller 19 of the traverse rail 7, Even if the pallet 10 moves further to the left and the wheels 18 and the short rails 26 are disengaged, the engagement between the brackets 17 and the flanged rollers 19 is changed to support the pallet.

This is because 11 in FIG. 20 is longer than 12, and when the pallet moves to the right from the traversing rail 7 side, the traversing wheels 18 transfer to the short rails 26 in the same manner.

Next, regarding vertical transfer, the movement of the pallet 11 located on the vertical transfer path 2' on the right side of the horizontal transfer path 1 in FIG. 4 toward the horizontal transfer path 1' will be explained.

That is, in the pallet 11 located at the upper right, each of the transverse wheels 18 is supported by the short rails 26 at both ends of the longitudinal carriage 24', and by clockwise rotation of the model 29, both the longitudinal carriages 24' and 24' move along the transverse transfer path 1. ’ side, and in the opposite direction move the vertical carriage 24.
24, they move to the side of the horizontal transfer path 1 side by side in an empty state.

In this case, the transverse wheels 18 are prevented from slipping off in the longitudinal direction by engagement between the flanges and the short rails 26. 24 itself is prevented from moving laterally.

Further, the traversing wheels 18 can be disengaged in the lateral direction by using two upper and lower traversing rollers 16 provided on the pallet and a groove-shaped guide rail 39.
39' and the intermediate guide rail 41,
This is prevented by being guided by a combination of at least two of the auxiliary guide rollers 42 to 47 and groove-shaped guide rails 48 and 49 provided on the pallet.

In addition, the connecting fittings 14 and 15 pass through the connecting fitting 13 of the lower pallet 10 and the connecting fitting 12 of the upper pallet 10, respectively, in this case, the first
As shown in Figures 4, 16 and 17, the grooved guide rail 39.
Collision is avoided by meandering by the dimension e by the bent portion formed at 39'.

Note that before the movement starts, the relative position of the bracket 17 and the flanged roller 19 is particularly at the notch 17a as shown in FIG.
This makes it possible to get over the flanged rollers 19, and the vertical carriage 24 is used exclusively for vertically transporting the pallet 10, and the longitudinal carriage 24' is exclusively used for vertically transporting the pallet 11.

Next, a method for moving the auxiliary parking pallet 10' to the side of the lift 50 from the state shown in FIGS. 1 and 4 will be explained.

As shown in FIG. 12, the pallets 10' are in an inclined upward position, and the upper pallet group is moved to the left, and the lower pallet group is moved to the right by simultaneous reverse operation of both lateral transfer modes 21, 21.

The pallet 10 at the left end of the upper row reaches the upper side of the vertical transfer path 2, and the transverse wheels 18 are placed on the short rails 26 at both ends of the longitudinal carts 24, 24.
is supported.

Next, when the pallet 10' is lowered by shortening the cylinder 62, the connecting fittings 12-15 are automatically engaged.

If only the model 21 on the lateral transfer path 1 side is reversed, the upper pallet group will integrally move to the right (only 1 pitch),
Traversing wheels 18 of pallet 10' are supported on short rails 26 of longitudinal carriages 24, 24.

In this case, when the transverse wheels 18 of the pallet 10' cross the gap formed on the side of the short rail 26 of the left longitudinal carriage 24 of the vertical transfer path 2, the flanged wheels 18 provided on the crossing rail 59
The brackets 17 and 17' are supported by the brackets 8 to ensure safe crossing.

Next, only the model 29 on the vertical transfer path 2 side is driven to move the pallet 10' to the lower row, that is, to the side of the lift 50, so that it is automatically connected to the pallet 11 at the left end of the lower row.

The pallet 10' can be stored in the auxiliary parking space 57 in exactly the reverse order.

Next, loading the pallet onto the lift 50 will be described.

After the desired pallet 10 or 11 is circulated until it comes to the lateral position of the lift 50, only the model 21 on the lateral transfer path 1' side is driven to move the pallet group one pitch to the left, and the target pallet is loaded onto the lift 50. Then, when the lift is raised by operating the lifting mode 53, the connecting fittings 12~
15 can automatically disengage and move the destination pallet to the entry compartment 4.

In this case, for example, when loading the pallet 11 on the vertical transfer path 2 in Figures 1 and 4 onto the lift 50, the traverse wheels 18 of the pallet are extended in the same manner as explained in Figures 20 and 21 above. It crosses the space between the rail 8' and the short rail 26, passes through the crossing rail 55, and transfers onto the rail of the lift 50, but what follows is the pallet 10, which is located on the vertical transfer path 2. is a vertical carriage 24' for transporting the pallets 11.

However, in this case as well, the traversing wheel 18 is connected to the extension rail 8'.
Even if the bracket 17 comes off and reaches the space, the rear part of the bracket 17 continues to engage with the flanged roller 19 of the extension rail 8', and the bracket 17 reaches the stop position (in this case, the state shown in FIG. 22, but as shown in FIG. The notch 17a provided in the bracket 17 is supported by the flanged roller 19, and the pallet 10 is slightly lower than its normal position, but there is no problem from the side.

The rear side of the pallet is also supported in the same manner as described above.

When the pallet 10 or 10' is mounted on the lift 50, the relationship between the longitudinal carriage 24 and the pallet 11 is established, and in this case, the pallet is supported in exactly the same manner as described above.

The pallet can be carried into the circulation path from the entry room 4 in the same manner as described above.

In addition, in the above explanation (in this case, the horizontal pallet circulation section and the auxiliary parking space were explained in one layer and the lift was installed only on one side), but if the length of the lift is increased, it can be made into a multi-layer structure, or even with a lift on both sides. It can be carried out in the same manner, and the pallet traversing means and the longitudinal carriage driving means are not limited to the above-mentioned structure, but may also be a known pinion and rack or crank lever system.

In addition, there are two types of pallets, one with widely spaced traversing wheels and one with narrowly spaced traversing wheels, and the same can be said of the traversing cart by reciprocating both wide and narrow traversing wheels that match the traversing wheels. It is possible to implement

Furthermore, the auxiliary parking rail can be raised and lowered between the upper and lower sides while maintaining the horizontal state using an appropriate lifting mechanism, or the auxiliary parking rail can be moved slightly vertically in the pallet using an appropriate drive device. It is possible to engage and disengage the connecting fittings.

As described in detail above, according to the present invention, the auxiliary parking space is provided in the space corresponding to the lift with a simple configuration, and is completely unrelated to the drive of the horizontal circulation section, and it is easy to enter and exit the auxiliary parking space. Since this can be done in a short time, it is possible to improve parking efficiency by effectively utilizing parking spaces at low equipment costs.
