DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0002]

2. Description of the Related Art For example, a hoistway of a car in elevator equipment is constructed by combining a number of guide rails made of long material. In general, guide rails that constitute an elevator shaft are linear and have the same dimensions.

Therefore, conventionally, when a large number of guide rails are connected with an elevator or the like to form a hoistway, many guide rails manufactured without considering the mutual relation between the individual rails at all. They are randomly selected from within and combined.

[0004] On the other hand, recently, the height of buildings has been increasing, and in particular, it has been required for a super-high-speed elevator provided in a skyscraper to operate a car at an ultra-high speed.

However, when the elevator is operated at high speed,
Depending on the combination of rails, vibration may occur in the car. This is thought to be due to the fact that each rail has its own bent shape.If rails are combined without considering the shape of the rails, the car may cause vibration in the lateral direction. This is because there is a possibility that a combination for applying a force may be established.

FIG. 19 is a view showing a state where a guide rail is formed by a conventional technique. If the guide rails are installed in such a combination as shown in the figure, there is a possibility that a large vibration is generated in the car traveling on the hoistway. It is also known that the vibration of an elevator increases almost in proportion to its speed.

[0007] In order to reduce the vibration generated in the elevator car, the problem can be solved by removing the bending of the individual guide rails. However, there are many problems such as high processing accuracy and quality control are required. .

Further, the rails may be installed so that a combination for applying a lateral force that causes vibration to the car is not established, but what kind of combination of rails can reduce vibration is as follows. Not fully understood.

In addition, ELEVATOR TECHNOL

The cleaning device 3 is provided on a transport line between the transport rollers 2a and 2b. A transfer device 5 is disposed between the transport rollers 2b and 2d.

The transfer device 5 has a pair of parallel conveyors 5a and 5b arranged in a direction perpendicular to the direction of conveyance of the guide rail 1 by the conveyance device 2, and the conveyors 5a and 5b The guide rails 1 and 1 'are moved in parallel in a direction perpendicular to the transport direction.

The operation is controlled by the control device 8 housed in the control panel 15.

The following operation is performed in the rail shape measuring device 30. First, before the measuring sensor 12 measures the degree of bending of the guide rail 1 carried in by the transport device 2, dust and dirt on the rail surface are removed by air by the cleaning device 3.

(4) The shape measurement data calculated by the calculation device 9 and expressed as Expressions (1) to (4) is stored in the memory of the combination simulation device 10.

Next, the combination simulation apparatus 10 in the control panel 15 will be described in detail. FIG. 4 is a block diagram illustrating a configuration of a main part of the guide rail combination determination device according to the present embodiment.

The combination simulation apparatus 10 shown in FIG. 2 stores a calculation result of the calculation apparatus 9 and a memory for storing a classification table and other processing contents in the simulation apparatus 10;

In accordance with the determination progress status, the combination determination unit 33 and the joint determination unit 34 perform a combination or a joint search to perform the search.

Next, the combination simulation apparatus 10
Will be described with reference to FIG. In other words, the combination is a combination of rails serving as a hoistway that can reduce vibration even in a high-speed elevator.

FIG. 5 is a flowchart for explaining a guide rail combination determining operation in the guide rail combination determining apparatus of the present embodiment. First, the simulation device 1
At 0, the shape data of each guide rail is read from the memory (S1), the shape data is analyzed by the pattern classifying unit 35, and the shapes having similar shapes are grouped and classified (S2).

For example, it is assumed that the patterns are classified into patterns A to J as shown in FIG. FIG. 6 is a diagram illustrating a classification pattern of guide rails. After the pattern classification is performed, the pattern classification unit 35 further performs, for example, grade classification as shown in FIG. 7 by focusing on the degree of bending of the rail for each pattern (S3).

FIG. 7 is a diagram illustrating the grade of the guide rail. Here, the grade a rail has the highest accuracy, and the accuracy gradually decreases from a to f. Therefore, at this stage (S3), the data is grouped by the two elements of the shape pattern and the grade, and for example, a classification table as shown in FIG. 8 is created.

FIG. 8 is a diagram showing an example of a classification table created from the classification patterns and grades of guide rails. In this embodiment, a guide rail combination is determined with reference to this classification table. Before describing the operation after step S4 in FIG. 5, the combination search criterion and the joint search criterion serving as the rail search criterion for making the determination will be described.

Here, the combination refers to a pair of guide rails. For example, elevators are often provided as a set with four guide rails for guiding a car on the same horizontal plane. However, it can be considered that these four guide rails are provided with two sets of two guide rails facing each other, and therefore, in the following description, a set of two guide rails facing each other will be described. Is treated as the above combination.

On the other hand, the term “joining” refers to a method of assembling two guide rails connected in the vertical direction. (Combination Search Criteria) First, a description will be given of a combination search criterion for which the combination determination unit 33 performs the search.

From the classification table shown in FIG. 8, a combination in which the shape of the guide rail is left-right symmetric for each group is searched. For example, a combination of A-a and Fa is a pair of rails facing each other. This combination is the combination having the highest accuracy, and this combination is positioned as a portion where the moving body travels at high speed.

FIG. 9 is a diagram showing a combination pattern of guide rails. In the case shown in FIG. 2A (hereinafter referred to as pattern (a)), a pair of rails facing each other is curved in the same direction, and a pair of rails subsequent thereto are also curved in the same direction.

On the other hand, in the case shown in FIG. 2B (hereinafter referred to as pattern (b)), a pair of rails facing each other are curved in opposite directions and are symmetrical left and right. The pattern (a) can be classified as a parallel movement type because the paired rails are parallel, and the pattern (b) is a left-right symmetric type because the paired rails are symmetrical. Can be classified.

Since the vibration of the elevator is known to increase almost in proportion to the speed, the pattern (b)
Is considered as one condition in determining the order of rail combination.

This will be described in detail with reference to FIG. FIG. 10 is a diagram showing a result of simulating the relationship between the traveling speed of the elevator and the vibration for each combination pattern.

From the simulation results shown in the figure, when the rail shape is of the parallel movement type, that is, in the case of the pattern (a), the elevator car receives the exciting force, so that the vibration increases with the increase of the traveling speed. Increase.

On the other hand, when the rail shape is symmetrical, that is, in the pattern (b), the force acting on the car is canceled by the bending of the rail, and the vibration is reduced.
From the simulation results, it can be seen that when the elevator runs at high speed, it is desirable that the shape of the guide rail be symmetrical in order to reduce vibration. That is, the combination of the guide rails is desirably the configuration of the pattern (b), and if such a combination is used, the elevator will have less vibration and a good ride comfort.

Therefore, in the present embodiment, a combination of guide rails is selected from among a large number of guide rails so that the combination becomes the configuration of the pattern (b) and the combination having the highest symmetry is obtained from the classification table. Is determined.

Next, analysis of the symmetry of the combination will be described with reference to FIG. FIG. 11 shows a method of analyzing the symmetry between each guide rail of a certain group (for example, the pattern A in FIG. 6) and each guide rail of another group (for example, the F pattern in FIG. 6) that is symmetrical to the group. It is shown.

As described above, the shape data of each guide rail in both groups is stored in the memory as d _H 1 _(n) and d _V 1.
_(n) , d _H 2 _(n) , d _V 2 _{(n), and the} like are stored in the form of a sequence. Using the measurement data, the displacement difference between the longitudinal measurement data d _V 1 _(n) of the rail # 1 and the longitudinal measurement data d _V 2 _(n) of the rail # 2 is determined for ten longitudinal positions of the guide rail. Te, formula for obtaining the Sawa T _V of the displacement difference is represented by equation (5).

[0075]

(Equation 1) The same applies to the horizontal measurement data.

[0076]

(Equation 2) Can be represented by

The sums T _H and T _V thus obtained are
Indicates the shape difference between the two rails # 1 and # 2, which are symmetrical to each other. In the present embodiment, the sum T of T _H and T _V is determined for each guide rail between the opposing patterns in the combination pattern. The set of rails having the largest sum T is the set having the highest symmetry.

Therefore, the pair of guide rails is determined in ascending order of the shape difference T between the rails. (Joint Search Criteria) Next, a joint search criterion for which the joint determination section 34 performs the search will be described.

As the joining search criteria, two types of search criteria will be described below. In the present embodiment, the determination operation shown in FIG. 6 is performed using the joint search criterion 1, but the joint search criterion 2 or 3 may be used as the joint search criterion for this.

Joint search criterion 1: When a number of guide rails are joined to form an elevator shaft, as shown in FIG. 12, if joints are not smooth, vibrations may occur. .

FIG. 12 is a diagram showing a state of joining the guide rails. Therefore, as shown in FIG. 13, it is necessary to determine the installation order of the guide rails so that not only the left-right symmetry of the combination but also the rail shape of the joint portion becomes smooth.

FIG. 13 is a diagram showing a case where the combination of guide rails in the elevator route has good symmetry and good joint. The suitability of the guide rail splicing is determined from the inclination of the rail end. Guide rails in which the inclination R _H of the rail end for the horizontal bending and the inclination R _V of the rail end for the vertical bending match each other are determined to have the highest suitability for splicing.

FIG. 14 is a diagram showing a method of determining the suitability of the joint according to the present embodiment. As shown in the drawing, the inclination of the rail end is obtained from the displacement of the guide rail at two places at the rail end. The following equations (7) and (8) are equations for calculating the inclinations R _H and R _V of the rail end in the lateral bending.

[0084]

(Equation 3)

[0085]

(Equation 4)

Next, a guide rail having high joining suitability is searched for from both patterns adjacent in the longitudinal direction of the traveling path. As described above, the guide rails having the same rail end inclinations R _H and R _V have the highest suitability for splicing. Therefore, for example, the following bends in the vertical direction so that the rail end inclinations become equal. Search for a combination of guide rails that satisfies equation (5).

[0087]

(Equation 5)

When a combination of symmetrical guide rails is determined, the suitability of joining the rails is determined for each combination. Splice search criterion 2: Another method for determining the suitability of splice will be described.

As an example, let us consider a case where there are seam search groups 1, 2, 3 as shown in FIG. FIG. 15 is a diagram exemplifying a joining set of guide rails.

For each of the figures, the difference between the reference straight line and the shape curve (the shaded area shown) is determined, and the group ((2) in the figure) that minimizes this difference is determined to be the one with the highest accuracy. In other words, assuming that, for example, a portion above the reference straight line is positive and a portion below the reference straight line is negative, an integrated value is obtained for the joint set, and the pair having the smallest value is selected.

Then, such a group is allocated to a portion that runs at the highest speed. Splice search criterion 3: This splice search criterion is a combination of the above seam search criterion 1 and search criterion 2.

When searching for a guide rail to be joined to a certain guide rail, in this method,
First, all sorts of guide rails having an integral value within an allowable range are searched from the classification table 31 based on the search criterion 2 based on the search criterion 2, and the guide rails are set as candidates for the guide rails to be joined.

Next, the search criterion 1 is applied to each of the candidates, and the guide rail having the highest compatibility is determined as a guide rail to be joined to the certain guide rail.

The combination search criteria and the joint search criteria serving as the rail search criteria have been described above. Next, the operation of determining the guide rail combination based on these search criteria will be described from step S4 in the flowchart shown in FIG.

In step S3, after the classification table is created, the rail combination determining / progressing unit 32
It is determined whether or not all combinations of the highest speed part have been determined (S4).

Next, first, at the start of the determination of the combination of the highest speed portion, one guide rail of the highest grade in the classification table is arbitrarily selected and set as the first one. On the other hand, if it is not the first one, the seam determination unit 34 performs a seam search for a rail to be connected to any of the guide rails combined in step S6 described below (S5). In this embodiment, the joint search criterion 1 is used among the above-described search criteria, but the search criterion 2 or 3 may be used.

Next, in step S5, the selection of the combination for the jointed rails is determined by the combination determination unit 3.
