Description

[Detailed Description of the Invention] The present invention relates to an improvement of pallet connecting fittings in horizontal circulation type parking equipment.

Conventionally, multiple pallets for vehicle loading were arranged on a transfer path consisting of two vertical and horizontal rows arranged in a rectangular shape so that two opposite corners were empty when stopped, and these pallets were fixed on both sides of each pallet. Adjacent pallets are connected horizontally to each other using the connecting fittings described later, and vertically and
There was a horizontal circulation type parking facility that alternately moved and circulated from one horizontal pitch to another. However, the pallet connection in this type of parking equipment was
As disclosed in Japanese Patent No. 46-18177, U- or U-shaped metal fittings were fitted from above and below.

In this case, in consideration of misalignment when the fittings are engaged with each other, the fittings have a considerable play, and the entrance portions are largely chamfered.

However, the more play there is in the fitting part mentioned above, the greater the positional deviation between the pulling side and the pushing side when they stop, and no matter how slow the vertical transport speed of the pallets is, the contact impact noise when they pass each other will be reduced. Unavoidably, sometimes a situation occurs in which mating becomes impossible.

In view of the above-mentioned current situation, this invention has a pair of female and male connecting fittings on the left and right sides of the pallet, with a level difference in the front and back, and is placed at the same level on the left and right sides. It is an object of the present invention to provide a pallet for use in horizontal circulation type parking equipment, the purpose of which is to eliminate any contact with the connecting fittings of the installed pallet.

To explain in detail the embodiment shown in the figure, 1, 1' and 2, 2' are a horizontal transfer path and a vertical transfer path formed parallel to each other in a rectangular shape, and 3 is an anti-lateral transfer path of the vertical transfer path 2. A lift 4 is provided as appropriate in a hoistway formed upward from the 1' side.

5, 5' are two lateral rails fixedly arranged in parallel on the lateral transport paths 1, 1', respectively;
Reference numerals 6', 7, 7' denote extension rails fixedly disposed at appropriate intervals from the ends of the transverse rails 5, 5' within the vertical transport paths 2, 2' on the extension lines of both ends of the transverse rails 5, 5'.

Reference numeral 8 designates a pallet for mounting on a vehicle, which is arranged so that when the circulating movement is stopped, there is empty space diagonally in both the vertical transfer paths 2, 2', and all of the horizontal transfer paths 1, 1' and the vertical transfer paths 2, 2'. One piece is connected and placed in the other.

The pallet 8 has female and male metal fittings 9a and 10a fixedly installed at the same level at the upper front of the left and right sides, and male and female metal fittings 10b at the same level at the lower rear of the left and right sides with a difference in level between the front and rear. The base ends of the female metal fittings 9a and 9b are appropriately fixed to the side surface of the pallet 8, and the other ends are fixed to the side surface of the pallet 8.
The male fittings 10a, 10 are bent in a letter shape.
In b, the proximal end of the drip plate-shaped portion is fixed to the side surface of the pallet 8, and the other end is bent at a right angle so as to fit into the U-shaped portion of the female metal fitting.

Reference numeral 11 denotes two flanged transverse wheels arranged at appropriate intervals on both ends of the lower surface of the pallet 8 in the vertical direction, and these wheels support the pallet by engaging with the transverse rails 5 and 5', and are driven by an appropriate driving method. This makes it possible to move the pallets in an integrated manner.

Reference numerals 12 and 12' designate vertical rails, which are arranged in sets of two each with a spacing slightly wider than the length of the extension rails 6, 6', 7, and 7', and are connected to the vertical transfer path 2,
2', it can be reciprocated between positions aligned with the transverse rails 5, 5' by an appropriate drive mechanism (not shown).

Thus, the horizontal and vertical transport of the pallet 8 is carried out alternately vertically and horizontally, and the opposing vertical and horizontal transport rows simultaneously move in opposite directions. Vertical transfer on the ' side will be explained.

In the vertical transfer, the vertical rail 12 on which the number pallet 8 is placed is transferred from the lateral transfer path 1' side to the lateral transfer path 1 side by driving a suitably arranged drive mechanism (not shown). In this case, between the number pallets 8 and 8, the female metal fittings 9a and the male metal fittings 10a, as well as the male metal fittings 10b and the female metal fittings 9b, can be separated in the vertical direction. ,8
will automatically break the connection. Then, as the transfer progresses further, the female fitting 9b of the number pallet 8 is transferred to the female fitting 9a of the number pallet 8 waiting on the side of the horizontal transfer path 1.
However, as shown in Fig. 4, both female metal fittings 9
Since there is a level difference between the upper and lower portions b and 9a, they do not come into contact with each other.

Then, at the final stage of the vertical transfer described above, the female metal fittings 9b and male metal fittings 10a of the number pallet 8 are transferred to the fifth and fifth pallets, respectively.
As shown in Figure 6, the male fitting 10b of pallet 8
is connected to the female fitting 9a in a fitted state, and the vertical transfer is completed.

In addition, the female metal fittings 9a, 9b and the male metal fitting 10
As long as the left and right pair of a and 10b are arranged at the same level, it is possible to use female metal fittings on one side or to change the top and bottom heights at the front and rear.

However, when loading the pallet 8 on a lift and transporting it to an entrance provided above or below the storage position, the female metal fittings 9a, 9b, male metal fittings 10a,
The openings and protrusions of the lift 10b must be arranged so that the connected side on the lift faces opposite to the entrance/exit, and the unconnected side faces toward the entrance/exit.

As detailed above, according to the present invention, a pair of male and female connecting fittings are arranged on the front and rear left and right sides at the same level position on the left and right sides with a difference in level between the front and back, and when the pallet is vertically transported, Since the connecting fittings do not come into contact with the connecting fittings of adjacent pallets, there is no need to increase the looseness of the connecting fittings.
In addition, there is no impact noise when pallets pass each other, and the spacing between pallets can be narrower than before, which improves site utilization efficiency and parking efficiency. Simple improvements to the connecting fittings can have great effects. It is.

An explanatory diagram of the state of the metal fittings when they pass each other, and FIGS. 5 and 6 are diagrams explanatory of the fitted state of the metal fittings. In the figure, 1 and 1' are horizontal transfer paths, 2 and 2' are vertical transfer paths, 8 is a pallet for mounting on a vehicle, 9a and 9b are female metal fittings, and 10a and 10b are male metal fittings.
