Description

[Detailed description of the invention] Industrial application field This invention is a rack-type multi-level parking system that stably holds pallets for loading automobiles in predetermined positions in automobile storage racks even in the event of an earthquake. This invention relates to a pallet position regulating device in a device.

Prior Art A rack-type multilevel parking system has been proposed in which cars loaded on pallets are stored in multiple stacks in a car storage rack, and a stacker crane is used to carry out the loading and unloading operations of the cars (for example, , Japanese Unexamined Patent Publication No. 176770/1983).

This item is made from the structural material of a car storage rack.
A pallet holder is installed horizontally, and the pallet holder supports both ends of a pallet loaded with automobiles from below.
The vehicle is configured so that the vehicles can be stored in multiple stacks in an orderly manner in the vehicle storage rack, and the vehicles can be carried in and out of the vehicle storage rack together with pallets using a stacker crane. When compared to conventional parking-type parking devices, since cars can be parked in multiple stacks, the number of cars that can be parked per unit land area can be significantly increased.

Problems to be Solved by the Invention According to the prior art, since the automobiles are loaded on pallets and stored in multiple stacks in the automobile storage rack, there is no risk of damage caused by an earthquake. If the shaking of the car storage rack becomes excessive, it cannot be said that there is no possibility that the pallet may come off the pallet receiver, causing an unexpected serious disaster. That is, the problem with conventional automobile storage racks is that the pallets are simply supported at both ends by pallet holders, and no special safety measures are taken.

Therefore, in view of the actual state of the prior art, the purpose of this invention is to take measures to actively control the position of pallets supported on pallet receivers, thereby making it possible to prevent automobile storage racks from being damaged in the event of an earthquake. Even if shaking occurs, pallets will not be accidentally dropped from the pallet receiver, and at the same time, special support will not be applied to loading and unloading of automobiles using stacker cranes. It is an object of the present invention to provide a new and considerate pallet position regulating device in a rack-type multilevel parking system.

Means for Solving the Problems The structure of this invention to achieve the above object is that the pallet holder is attached to the structural member of the car storage rack and supports both ends of the pallet for loading the car. First to third regulating pieces protruding from the upper surface are arranged, and the first regulating piece regulates the position of the pallet in the forward direction, and the second regulating piece regulates the position of the pallet in the forward direction.
The regulating piece regulates the position of the pallet in the left and right direction, the third regulating piece regulates the position of the pallet in the backward direction, and the first regulating piece regulates the position of the pallet in the backward direction.
The gist is to form it higher than the third regulating piece.

With this configuration, when a pallet is stored in a predetermined position on the upper surface of the pallet receiver using a stacker crane, the first regulating piece regulates the forward limit of the pallet, and Since the third regulating piece can regulate the position of the pallet in the left and right direction, the pallet can be easily placed in a fixed position.

In this way, even if an earthquake occurs while the pallets are supported and stored in the pallet holder and the car storage rack shakes violently, the
The pallet is controlled by the first to third regulating pieces.
Since the movement of the pallet back and forth and left and right is restricted, there is no fear that the pallet will inadvertently come off the pallet receiver and fall off.

Note that the above explanation holds true regardless of whether or not a car is loaded on the pallet.

It works as described above.

Example Examples will be described below with reference to the drawings.

The pallet position regulating device in the rack type multi-level parking system has a first regulating piece 2 on each of the pallet receivers 10, 10 for supporting the pallet P.
1, a second regulating piece 22, and a third regulating piece 23 (FIGS. 1 and 2).

The pallet P is a rectangular plate-like body on which a car C can be loaded, and its upper surface has grooves Pa, Pa for driving the tires Ct, Ct... of the car C, and grooves Pa, Pa for stabilizing the tires Ct, Ct... recess for positioning
Pb, Pb... are formed.

The pallet receivers 10, 10 support the structural members Ra, Ra...
A pair of objects are protruded horizontally from each other, facing each other. However, the car storage rack R is a structure formed by combining vertical structural members Ra, Ra... and the outer wall surface Rb, and is designed to accommodate the cars C loaded on the pallet P in multiple stages. It is assumed that the Further, if necessary, by arranging similar ones on the left and right sides, it is also possible to accommodate a large number of cars C in the form of shelves.

One side of the wall surface Rb of the vehicle storage rack R is open, and by inserting telescopic fork devices F, F of a stacker crane (not shown) under the pallet P and moving it up and down, the vehicle C can be opened.
A pallet P is carried in in the direction of arrow K in Fig. 1 with or without loading, and
It shall be possible to carry it out in the opposite direction.

The pallet receiver 10 has a front arm member 11 and a rear arm member 12 horizontally protruding from the front and rear structural members Ra, Ra, and the tips of both arm members 11 and 12 are connected to each other via a beam member 13. are connected. However, here, the front arm member 11 is bent into a hook shape, while the rear arm member 12 is formed in a straight line, but the shape of these arm members is different from the front and rear structural members.
It can be determined arbitrarily depending on the relative relationship between the spacing between Ra and Ra and the short side dimension of the pallet P. Furthermore, the length of the girder 13 is longer than the short side dimension of the pallet P, and the length of the girder 13 is longer than the short side dimension of the pallet P.
The spacing between the girders 13 and 13 of 0 and 10 is based on the pallet P.
It shall be shorter than the long side dimension of.

The first regulating piece 21 is a plate material protruding from the tip of the beam member 13 of the pallet receiver 10 (see FIG. 3).
(Fig. 4), the protrusion height h1 from the upper surface of the pallet receiver 10 is the height h1 of the pallet P lifted upward from the upper surface of the pallet receiver 10 during loading and unloading.
It is assumed that h1>d for the flying distance d.

The second regulating piece 22 is a plate member with an L-shaped cross section that protrudes from the upper surface of the rear arm member 12 (FIGS. 4 and 5), and is located above the side end facing the pallet P. A diagonal notch 22a is formed in the. A pair of second regulating pieces 22, 22 are provided so as to sandwich the long sides of the pallet P (FIG. 2). Further, the height h2 is set to be somewhat smaller than the thickness dp of the pallet P (FIG. 5).

The third regulating piece 23 is a plate material fixed to the rear end surface of the beam member 13 and bent diagonally to protrude from the upper surface of the pallet receiver 10 so as to have a height h3 lower than the thickness dp of the pallet P. Yes (Figures 4 and 5).
However, this height h3 is different from that of the other regulating pieces 21 and 22.
h1>h2>h3 compared to the respective heights h1 and h2.

Now, using a stacker crane (not shown),
Consider the case where a pallet P is stored on the upper surface of the pallet receivers 10, 10. In addition, at this time, the automobile C may be loaded on the top surface of the pallet P.
Also, it does not have to be loaded.

Since the pallet P conveyed from the outside is placed on the telescopic fork devices F, F of the stacker crane, the stacker crane is stopped at an intermediate position between the pair of pallet receivers 10, 10, and then , the bottom surface of pallet P is pallet receiver 10,10
The telescopic fork devices F, F are positioned so that they are higher than the upper surface by a flying distance d. After that, if the telescopic fork devices F and F are extended, the pallet P
moves forward in the direction of arrow K in FIGS. 1 and 4 and is inserted above the pallet receivers 10, 10 at a distance of floating distance d.

Here, since the first regulating pieces 21, 21 have a height h1 larger than the floating distance d, the pallet P
The forward limit of the front long side is the first regulating piece 2.
1 and 21, and can regulate its position in the forward direction. Generally, the extension distance of the telescopic fork devices F, F should be controlled separately, and the pallet P is not positioned by the contact between the first regulating pieces 21, 21 and the pallet P. . However, the first regulating pieces 21, 21 are
In this way, it can function as a safety device that backs up the operation of the telescopic fork devices F, F.

Next, when the telescopic fork devices F, F are lowered and positioned below the pallet receivers 10, 10, the pallet P is transferred from the telescopic fork devices F, F to the pallet receivers 10, 10, and both ends thereof are , and is supported by the pallet receivers 10, 10. Here, even if the lowering position of the pallet P has a slight error to the left and right from the predetermined position, the second regulating pieces 2 disposed on the left and right
2, 22, especially the notches 22a, 22a, the position of the pallet P in the long side direction can be corrected. Therefore, the second regulating piece 22,
Reference numeral 22 makes it possible to effectively control the position of the pallet P in the left and right direction.

In this way, the long side of the rear side of the pallet P placed on the pallet receivers 10, 10 is on the forward direction side than the third regulating pieces 23, 23, so that
Thereafter, the position of the pallet P is regulated by the first regulating pieces 21, 21 in the forward direction, and by the second regulating pieces 22, 22 in the left-right direction.
Accordingly, the position of the vehicle in the backward direction is further regulated by the third regulating pieces 23, 23, respectively. Therefore, an earthquake occurred,
Even if the automobile storage rack R is shaken violently, the possibility that the pallet P will inadvertently come off the pallet receivers 10, 10 and fall off can be minimized.

When carrying out the pallet P on the pallet receivers 10, 10, the telescopic fork devices F, F are inserted below the pallet P, and then raised to make the pallet P float above the pallet receivers 10, 10. It is sufficient to transfer it onto the telescopic fork devices F, F by using the above method, and then shorten the telescopic fork devices F, F. At this time, it goes without saying that it is sufficient for the pallet P to float higher than the height h3 of the third regulating pieces 23, 23.

In addition, each height of the first regulating pieces 21, 21, the second regulating pieces 22, 22, and the third regulating pieces 23, 23
Since h1, h2, and h3 are set as h1>h2>h3, when carrying in the pallet P, first the first regulating piece 21,
21 becomes effective in the forward direction, and then the regulation by the second regulating pieces 22, 22 and the third regulating piece become effective.
Since the restrictions by the third restriction pieces 23, 23 become effective in this order, not only can the loading operation be carried out smoothly, but also the height of the third restriction pieces 23, 23 can be
Since h3 is the minimum, the floating distance d of the pallet P required for loading and unloading can be minimized.

Effects of the invention As explained above, according to this invention, the first to third regulating pieces are arranged on the upper surface of the pallet receiver that supports the pallet, and each regulating piece is arranged in the forward direction of the pallet and in the left and right directions. By regulating each position in the direction and backward direction, even if the car storage rack shakes during an earthquake, the position of the pallets on the pallet receiver can be controlled from each direction. This makes it possible to effectively eliminate the risk of pallets inadvertently shifting their position and falling from the pallet holder.Furthermore, the restriction piece is particularly effective when loading and unloading pallets using a stacker crane. It has the excellent effect of not being a hindrance and being able to be effectively used for positioning during transport.
