Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a sensor mounting device for a mechanical parking facility. More specifically, a vertical circulation type parking facility that sequentially accommodates vehicles while circulating a plurality of vehicle accommodation pallets up and down, or a vehicle placed on a pallet in an entry / exit room and ascending and descending to a predetermined hangar floor. The present invention relates to a device for mounting a vehicle position confirmation sensor disposed in a parking facility for moving a vehicle.

[0002]

2. Description of the Related Art In a mechanical parking facility, a vehicle is placed on a pallet for transporting the vehicle, and is moved up and down and transported. When the vehicle gets on such a pallet, it is necessary to confirm whether or not the vehicle is within a predetermined range E on the pallet P as shown in FIG. This is because the vehicle M
Is used to prevent a part of the equipment from interfering with a part of the equipment, and is also used to confirm that no person remains on the pallet P. It is also necessary to check the open / closed state of the door of the entrance L to the pallet.

For such confirmation, a photoelectric sensor S or the like is conventionally provided at a predetermined height at a predetermined location near each boundary of the predetermined range E as shown in FIG. Thereby, an accident is prevented by, for example, issuing an alarm when a portion of the vehicle is out of the predetermined range. A plurality of sensors are provided in the height direction and the horizontal direction so as to correspond to various sizes and types of vehicles to be accommodated.

FIG. 6 shows a conventional sensor mounting device 51.
It is.

[0005] The sensor mounting device 51 comprises a base member 52 fixed to the floor surface and a mounting member 53 nested on the base member 52. Mounting member 5
A fixed plate 54 inclined to the light emitting direction or the light receiving direction of the sensor S is fixed to 3 by welding or the like, and the sensor is fixed to this fixed plate 54 via a bracket 55 in a predetermined direction. ing.

A bolt hole 56 is formed in the base member 52, and a long hole 57 for position adjustment is formed in a corresponding portion of the mounting member 53. By doing so, it is possible to adjust the vertical position of the mounting member 53, and thus the vertical position of the sensor S, within the range of the elongated hole 57. Normally, the lengths of the base member 52 and the mounting member 53 are determined in advance according to the type of vehicle to be accommodated, and the vertical position is finely adjusted at the stage of installation.

[0007]

However, according to the above-described conventional sensor mounting device 51, only one sensor can be mounted at one location. If a plurality of units are to be mounted, the fixing plate 54 and the bracket 55 will have a complicated shape, and the mounting will be troublesome. Therefore, a significant cost increase must be accepted. In addition, since the adjustment width in the vertical direction is extremely small, and in addition, since the directivity direction of the sensor is fixed, the level of the installation surface of the sensor mounting device 51 is changed due to various factors, or the plan of the accommodation vehicle type is changed. Then, the adjustment becomes impossible immediately, and the sensor mounting device 51 itself must be replaced.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and has as its object to provide a sensor mounting device for mechanical parking equipment which can easily change and adjust the mounting position of a sensor with a simple structure. I have.

[0009]

With this configuration, the sensor is mounted on the mounting member, and then the mounting member is moved along the support column and fixed at a desired position, so that the sensor can be steplessly set within the length of the support column. Can be adjusted. Of course, the sensor may be mounted after setting the position of the mounting member.

Therefore, if the support column is installed vertically, the vertical position of the sensor is adjusted steplessly, and if it is installed horizontally, the horizontal position of the sensor is adjusted steplessly.

The mounting member includes a holding means movably attached along the supporting column and a sensor mounting bracket mounted on the holding means, and holds the holding means at an arbitrary position on the supporting column. By being configured to be fixed, mounting of the sensor becomes easy,
Furthermore, by adopting a means of clamping, a means that enables movement along the support column and fixation at a desired position can be easily selected.

[0013] Further, the holding means comprises an abutting portion which abuts on the support column, a pair of bolt portions projecting from both sides of the support column to both sides of the support column, and a nut which can be screwed to the bolt portion. By configuring the sensor mounting bracket and the contact portion to clamp the support column by tightening a nut to a bolt portion, a commercially available product can be used,
Moreover, the structure can be simplified. With such a structure, the above-described functions and effects can be obtained.

Further, by combining the abutment portion and the bolt portion with a u-bolt, the utilization rate of commercially available products is increased, the structure is further simplified, and the handling is facilitated.

[0015] Further, the mounting bracket is formed with a pivoting portion capable of pivoting one point of the sensor so as to swing freely.
An arcuate guide portion for guiding the swing of the sensor is formed at a position separated from the pivot portion, and the sensor mounting device has a fixing means for fixing the sensor at an arbitrary position of the arcuate guide portion. Thus, the directivity direction of the sensor can be easily adjusted. For example, if a pivot portion and a guide portion are provided on a vertical portion of the bracket, the directivity direction can be adjusted vertically, and if a pivot portion and a guide portion are provided on a horizontal portion, the directivity direction can be adjusted horizontally. A known means such as a bolt may be used as the fixing means.

In addition, the mounting bracket has a horizontal plate portion and a vertical plate portion that can be horizontally moved and fixed on the upper or lower surface of the horizontal plate portion, and the sensor is mounted on the vertical plate portion. In the sensor mounting device configured to be mounted, the horizontal position adjustment of the sensor is also possible.

[0017] In the claims, "horizontal",
"Vertical" means that when the support column is installed substantially vertically, the direction perpendicular to the support column is called horizontal, and the longitudinal direction of the support column is called vertical, and it is absolutely horizontal. It is not used as the direction and the vertical direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a sensor mounting device according to the present invention will be described with reference to the accompanying drawings. First, FIG.
(A) is a front view of the sensor mounting device 1, and FIG.
Is a side view thereof.

In this embodiment, the support columns 2 are installed vertically on the floor F. However, the present invention is not limited to the vertical direction, and may be horizontal or inclined. In addition, although a pipe having a circular cross section is used as the support column 2, it is not limited to a circular cross section. However, in the present embodiment, since the U-bolt 3 is used as a means for holding the support column 2, the support column 2 preferably has a circular cross section.

It is desirable that the inner radius of the U-bolt 3 is substantially the same as or slightly larger than the outer radius of the support column 2. A sensor mounting bracket (hereinafter, simply referred to as a bracket) 4 having two bolt holes is attached to the U-bolt 3 by a nut 5 so that the support column 2 is sandwiched between the U-bolt 3 and the U-bolt 3.

As is clear from FIG. 2 as well,
The bracket 4 includes a horizontal plate member 6 and a vertical plate member 7. The horizontal plate member 6 is formed of a plate material having an L-shaped cross section, and the vertical portion 6a has the above-mentioned bolt hole 6b for the U-bolt 3, and the horizontal portion 6c has the vertical plate member 7 bolted thereto. Bolt holes 6d are formed. The vertical plate member 7 is also formed of a plate material having an L-shaped cross section, and the horizontal portion 7a has the horizontal plate member 6 formed thereon.
The vertical portion 7c has a bolt hole 7d for pivotally supporting the sensor S and a guide hole comprising an arc-shaped long hole for guiding the swing of the sensor S. 7e are formed.

The bolt hole 6d of the horizontal portion 6c of the horizontal plate member 6
Are formed to adjust the mounting position of the vertical plate member 7 in the horizontal direction (arrow G in FIG. 2). Of course, six or more bolt holes 6d may be formed so that the positions can be adjusted at three or more locations. Further, instead of four or more bolt holes, a long hole may be formed in the lateral direction so that the position can be adjusted steplessly.

The sensor S is connected to the vertical plate member 7 at one point.
The bolt 8 is pivotally supported by a bolt 8 through a bolt hole 7d, and a point separated from the one point is supported by the bolt 9 through the guide hole 7e. By doing so, the sensor is swung up and down (arrow H in FIG. 1) about the pivot point and fixed by bolting at an arbitrary angle. Thereby, the vertical direction of the light emitting unit (or light receiving unit) of the sensor S can be adjusted.

Further, by loosening the nut 5 of the U-bolt 3, the vertical position of the sensor S with respect to the support column 2 can be changed and adjusted. Further, by using the support pillar 2 having a circular cross section, the U-bolt 3 can be rotated around the support pillar 2, so that the directivity direction of the sensor S can be changed and adjusted in the horizontal direction (arrow V in FIG. 1). . Of course, by using a support pillar having a rectangular cross section, the U-bolt 3 may not be able to be rotated around the support pillar.

As shown in FIG. 1, a plurality of sets of the sensor S and the bracket 4 may be attached to the support column 2 as necessary.

A sensor mounting device 11 shown in FIG. 3 is provided with a bracket 12 having a different form from that shown in FIG. 1 (attached to a lower portion of the support column 2). The bracket 12 corresponds to the bracket 4 shown in FIG.
Is rotated 180 degrees. That is, the horizontal plate member 13 is attached to the support column 2 so that the horizontal portion 13a faces downward, and the vertical plate member 14 is attached so as to hang down on the lower surface of the horizontal portion 13a. Further, the vertical portion 14 of one vertical plate member 14
A plurality of sensors S are attached to a. Each of the sensors S can be adjusted in the lateral direction as in FIG. 1, and is mounted so as to be swingable in the vertical direction.

In the brackets 4 and 12 shown in FIGS. 1 to 3, the vertical plate members 7 and 14 are moved laterally on the horizontal plate members 6 and 13 so that the positions thereof can be adjusted. The present invention is not particularly limited to such a structure. For example, a plurality of types of vertical plate members 7 and 14 having different lengths of the horizontal portion are prepared, and the vertical position of the sensor S with respect to the support column 2 can be determined by selecting the vertical plate members 7 and 14 as necessary. Can be changed. Also, in place of the bracket in which the horizontal plate member and the vertical plate member have a separate structure as shown in FIGS. 1 to 3, the present invention uses a bracket in which the horizontal plate member and the vertical plate member are integrated. You may. That is, the lateral mounting position of the sensor S on the horizontal portion is different,
In addition, a plurality of types of brackets having different numbers of sensors S attached to one bracket are prepared, and if the brackets are selected as necessary, the position of the sensors S in the lateral direction with respect to the support column 2 and the number of mountings can be changed. Can be. By doing so, fine adjustment operations are omitted. Further, by making all the support columns the same thickness and the same length, making all the sizes of the U-bolt 3 and the like the same, and preparing the above-mentioned plural kinds of brackets, it is possible to standardize the parts of the sensor mounting device.

Either form of the bracket described above can be used to change the lateral mounting position of the sensor S as shown in FIGS. In FIG. 1, the sensor S is attached along the center line of the support column 2, in other words, the direction of the sensor S is the radial direction in the cross section of the support column 2 (see FIG. 1A). . Further, in FIG. 3, the sensor S is mounted such that the sensor S is shifted laterally from the center line of the support column 2, in other words, the directional direction of the sensor S deviates from the radial direction in the cross section of the support column 2 (FIG. a)).

FIG. 4 shows a sensor mounting device 21 according to a different embodiment.

In this sensor mounting device 21, the support column 22 is composed of two column elements 22a parallel to each other. And, instead of the above-mentioned U-bolt, a holding plate 23a in which a plurality of bolt holes 23b are formed in a row in the vertical direction.
And two bolts 23 penetrating into the bolt holes 23b.
c). The gap between the two pillar elements 22a has a size just enough to insert the bolt 23c. By doing so, the position of the holding means 23 can be adjusted up and down in a state where it cannot rotate around the support column 22.

The horizontal plate member 25 of the bracket 24
In the horizontal portion 25a, a bolt hole 25b for pivotally supporting the vertical plate member 26 and a guide hole 25c formed of an arc-shaped long hole for guiding the horizontal swing of the vertical plate member 26 are formed. . By doing so, the vertical plate member 26
Is mounted by pivotally supporting one point of the horizontal portion 26a in a horizontal direction by a bolt 27, and supporting a point apart from the one point by the bolt 28 through the guide hole 25c. By doing so, the vertical plate member 26 is swung laterally about the pivot point together with the sensor, and is fixed at an arbitrary angle by bolting. Thereby, the horizontal directivity of the light emitting unit (or light receiving unit) of the sensor S can be adjusted.

The structure of the vertical plate member 26 is the same as that shown in FIGS. In addition, the bolt 23c is attached to the holding plate 2
Instead of being separated from 3a, it may be protruded from the holding plate 23a by implantation or the like.

Further, such a vertical plate member capable of swinging in the lateral direction and a corresponding horizontal plate member can be applied to the sensor mounting devices 1 and 11 shown in FIGS. This is particularly useful in the case of a structure in which the Eubolt cannot be rotated using a support column having a rectangular cross section.

In the above embodiment, the U-bolt and the holding means shown in FIG. 4 are used for fixing to the support column, but the present invention is not limited to using the function of holding for fixing. For example, as shown in FIG. 4, a member or the like that is inserted into the gap between two column elements and fixed by utilizing frictional force while elastically protruding against both column elements may be used.

[0035]

According to the present invention, the sensor can be fixed at a desired position on the support column by moving the holding means along the support column. Moreover, the position of the sensor can be adjusted steplessly within the range of the length of the support column.
In addition, standardization of the sensor mounting device becomes possible.
