Abstract

PROBLEM TO BE SOLVED: To provide an elevator control panel by which both of following sounds (noise) can be suppressed, and which can be made compact in size, especially, in thickness by reducing the depth of an electromagnetic control device though noise generated by an electromagnetic control device is roughly divided into a sound (airborne sound) generated by the electromagnetic control device itself in the open/close operation and the other sound (solid borne sound) generated by the propagation of vibration caused by the open/close operation.SOLUTION: The elevator control panel is mounted with the electromagnetic control device. A housing box constituted of a ceiling wall, respective side walls and a bottom wall is attached to the attaching plane of the elevator control panel. The whole inner wall surface of the housing box is covered with a buffer member constituted of an acoustic material to form an electromagnetic control device housing chamber. The electromagnetic control device is held by the buffer member via an attaching member in the electromagnetic control device housing chamber.

Description

  The present invention relates to attachment of an electromagnetic control device mounted in an elevator control panel for the purpose of controlling the operation of the elevator.

  Most recent elevators are of a type without a machine room in which a control panel is installed in a hoistway. An electromagnetic control device for controlling the operation of the elevator is mounted in the elevator control panel, such as an electromagnetic contactor that opens and closes an electric circuit by the operation of an electromagnet. These electromagnetic control devices emit a loud sound or vibration when opening and closing. The type equipped with a machine room has a dedicated space for installing the control panel, and because the control panel itself is easy to have a sealed structure, there was no need to consider noise caused by electromagnetic control equipment, but it was installed in the hoistway. Noise generated by the electromagnetic control device in the control panel is easily heard by the customers in the car and the people adjacent to the hoistway, so it is necessary to take soundproofing measures. When an electromagnetic control device is mounted on a conventional elevator control panel, the electromagnetic control device is attached to a substrate or stored in a storage box, and a vibration isolating material is provided between the substrate or the storage box and a fixing member of the control panel. To prevent the vibration of the electromagnetic control device from being transmitted to the control panel (for example, Patent Documents 1 and 2).

Japanese Utility Model Publication No. 60-177441 JP 2001-310880 A

  Noise generated by the electromagnetic control device can be broadly divided into sound generated by the electromagnetic control device itself during the opening / closing operation (air propagation sound) and sound due to the propagation of the vibration caused by the opening / closing operation (solid propagation sound). It is mainly designed to suppress solid-borne sound and is not effective in suppressing air-borne sound. Therefore, it is not suitable for a control panel without a machine room where a control panel is installed in the hoistway. is there.

Moreover, in patent document 2, although an air propagation sound can be suppressed with a storage box and a solid propagation sound can be suppressed with a buffer member, since the noise is implemented with a separate measure, Large soundproof space is required. For the type without machine room, downsizing of the control panel, especially thinning, is a major issue in order to secure the effective area of the car on which the customer is placed in the hoistway. It is an obstruction factor. As an example of countermeasures, there is a method of mounting electromagnetic control equipment so that it is arranged on the side part of the control panel. In that case, periodic maintenance work occurs, not only with the problem of workability due to the fact that it is not arranged on the front part. In the elevator control panel, the electromagnetic control device cannot be seen from the front, so that there is a problem that it takes extra time for maintenance work.
The present invention has been made to solve the above-described problems, and suppresses both air-propagation sound and solid-propagation sound generated by the electromagnetic control device and reduces the depth of the electromagnetic control device for control. The purpose is to realize a reduction in the size of the panel, in particular, a reduction in thickness, and to facilitate maintenance and replacement work of electromagnetic control equipment.

  An elevator control panel according to the present invention is an elevator control panel in which an electromagnetic control device is mounted, and a storage box composed of a ceiling wall part, each side wall part, and a bottom wall part is provided on the mounting surface of the elevator control panel. An electromagnetic control device storage chamber is formed by covering and covering the entire inner wall of the storage box with a buffer member made of a sound absorbing material, and the electromagnetic control device is attached to the buffer member via the mounting member in the storage chamber. It is held.

According to the elevator control panel of the present invention, air propagation sound and solid propagation sound are stored in the storage box by directly mounting the electromagnetic control device on the fixed member of the control panel without using a buffer member. Since both of the suppression effects can be obtained, the space required for providing the buffer member outside the storage box is unnecessary, and the control panel can be downsized.
Therefore, it is possible to suppress the sound and vibration generated when the electromagnetic control device mounted in the control panel opens and closes from leaking outside the control panel.
In addition, when applying soundproofing to electromagnetic contactors as in the past, if measures were taken individually for airborne sound and solid-borne sound, an increase in the soundproofing structure was unavoidable due to both measures, and the soundproofing structure increased. Although this is an obstacle to downsizing the control panel, in this invention, it is decided not to cover and suppress the buffer member outside the storage box body, but to take measures against noise inside the storage box body. In addition to the sound insulation effect due to the noise, the sound absorption effect and the vibration isolation effect can be expected by the buffer material having the sound absorption performance, and the storage box can be downsized.

Embodiment 1 FIG.
1 is a cross-sectional view showing an elevator control panel according to Embodiment 1 of the present invention.
The electromagnetic control device 4 is held and attached by a buffer member 70 via an attachment member 50 as will be described later in an electromagnetic contact device storage box 60 attached to the attachment surface 3 a of the back plate 3.
An electromagnetic control device storage chamber R is formed in the electromagnetic contact device storage box 60 by covering the entire inner wall with buffer members 71 to 75, and the electromagnetic control device 4 is mounted in the storage chamber R. 50 and is held by the buffer member 70.

The electromagnetic contact device storage box 60 is made of a sound insulating material (for example, sheet metal), and is configured in a box shape with a ceiling wall portion 63, a bottom wall portion 64, and four side wall portions 61 and 62.
The shock absorbing member 70 is a member having a sound absorption and vibration proofing effect. The electromagnetic control device storage chamber R includes a ceiling wall cushioning member 73 that covers the ceiling wall, a bottom wall cushioning member 74 that covers the bottom wall, and four sides. It is comprised by the side wall buffer member 71,72,75 which covers the surrounding side wall part. Here, a buffer member having an adhesive sheet on one side may be used for covering the inner walls of the buffer members 71 to 75, or a double-sided tape (not shown) is accommodated with the buffer member. It may be arranged between the inner walls of the box and bonded.

  Thus, in the electromagnetic contact device storage box 60, the ceiling wall 63 is the ceiling wall cushioning member 73, the bottom wall 64 is the bottom wall cushioning member 74, and the side walls 61 and 62 are the side wall cushioning. Since the members 71, 72, and 75 are respectively held, the buffer member 70 originally propagated the vibration of the electromagnetic control device 4 in addition to the holding function for holding the electromagnetic control device in the storage box. There is an anti-vibration effect against the vibration of the mounting plate 51. Further, a sound absorbing effect can be expected by using a material having sound absorbing performance for the buffer member. Further, since the electromagnetic control device 4 is covered with the storage box 60, there is a sound insulation effect. By taking such various measures, noise caused by the electromagnetic control device 4 can be suppressed.

  Further, when a plurality of electromagnetic control devices 4 are desired to be stored in the storage box 60 at a time by using the mounting plate 51, it is easy to fix the plurality of electromagnetic control devices 4 to the mounting plate 51 at regular intervals. Since it becomes feasible, it is more useful.

  1, the mounting member 50 is composed of a U-shaped mounting plate 51, a DIN rail 52, a mounting screw 53, and a mounting screw hole 53a. However, when mounting the electromagnetic control device 4, the DIN rail 52 is mounted. There is no problem even if the mounting plate 51 is screwed directly to the mounting plate 51 without being used. Here, holding | maintenance of the attachment member 50 in the electromagnetic control apparatus storage chamber R shall be achieved only by the buffer members 71-75 to the last. With this structure, for example, when the electromagnetic control device 4 is replaced after the elevator is installed, the mounting member 50 can be easily taken out after the storage box ceiling portion 60 is removed. There is an advantage that can be implemented in time.

Embodiment 2. FIG.
The mounting plate 51 for fixing the electromagnetic control device 4 is structured to be held by the buffer member 70, but the original performance of the mounting plate for mounting the electromagnetic control device 4 on the mounting plate 51 as shown in FIG. 2 is not impaired. A hole for avoiding contact with the buffer member 70, for example, a square hole 51c, may be provided in a portion where the mounting plate 51 and the buffer member 70 are in contact with each other, that is, a surface in contact with the buffer member 70.
The mounting plate 51 has a U-shaped cross section having a mounting plate upper side portion 51a and a mounting plate lower side portion 51b, and the square holes 51c are also provided in the mounting plate upper side portion 51a and the mounting plate lower side portion 51b. Yes.

  The vibration generated by the electromagnetic control device 4 propagates to the mounting plate 51, but a damping effect can be expected by the buffer member 70. Here, by providing a hole in the mounting plate 51, the contact area between the mounting plate 51 and the buffer member 70 can be reduced, and the electromagnetic control device 4 can contact the vibration propagated to the contact surface of the buffer member 70 via the mounting plate 51. Since the area can be reduced, noise generated by the electromagnetic control device 4 can be further suppressed. That is, the amount of vibration itself propagating to the outside by the mounting plate 51 can be reduced, and the anti-vibration effect in the storage box is further enhanced.

Embodiment 3 FIG.
In FIG. 2 described above, a hole is provided in a portion where the mounting plate 51 and the buffer member 70 are in contact with each other, but the hole shape may be an ellipse 51d or a circle (not shown) as shown in FIG.
When the electromagnetic control device 4 operates, the mounting plate 51 also vibrates, and there is a concern that the durability of the buffer member 70 in contact with the mounting plate 51 may be impaired. Therefore, it is generally effective to deburr the holes when the mounting plate 51 is provided. However, the mounting plate 51 can be easily deburred by rounding the perforated shape of the mounting plate 51. This makes it possible to further suppress the damage of the buffer member 70 in the vicinity of the perforated location where there is a concern without impairing workability.

Embodiment 4 FIG.
Further, it has been described that the buffer member 70 originally has a function of holding the electromagnetic control device 4 inside the storage box. 2 and 3, the vibration damping effect is enhanced by providing the holes 51c and 51d in the contact portion between the mounting plate 51 and the buffer member 70. Instead of providing the mounting plate 51 with a hole, FIG. In this way, a plurality of small buffer members 71a, 72a, 73a, 74a are arranged within a range that does not impair the main purpose of the buffer member 70 for holding the mounting plate 51 in the storage box, that is, the buffer member 70 is divided into a plurality of walls. A structure may be adopted in which the parts are arranged with a predetermined separation distance.

According to this structure, the contact area between the mounting plate 51 and the buffer member 70, that is, the contact area of the vibration that the electromagnetic control device 4 propagates to the buffer member 70 through the mounting plate 51 can be reduced. At the same time, the durability of the buffer member 70 can be improved. Note that the size and the number of the buffer members 70 to be used may be determined in consideration of the purpose of holding the mounting plate 51 in the storage box 60 and the improvement of the vibration proofing effect by reducing the contact area with the mounting plate 51. .

Embodiment 5 FIG.
Further, in FIG. 1, a storage box body 60 configured in a box shape with a ceiling wall portion 63, a bottom wall portion 64, and four side wall portions 61 and 62 is attached to the back plate 3 of the control panel 1. However, as shown in FIG. 5, the bottom wall portion 64 facing the mounting surface 3a of the back plate 3 is removed from the wall surface of the storage box body to expose the buffer member 74, and the buffer member 74 is exposed. The exposed surface 740 may be brought into surface contact with the mounting surface 3a, and the bottom of the storage box 60 may be substituted with the back plate 3 of the control panel.
According to this structure, since the four wall portions are directly fixed to the back plate 3 of the control panel, the thickness of the bottom wall portion of the storage box body is maintained while maintaining the sealing property of the storage box body 60, that is, the sound insulation effect. Therefore, it is possible to further reduce the height and thickness of the control panel (the depth of the control panel is the bottom plate).

Embodiment 6 FIG.
Further, in FIG. 5, the storage box body is assembled by providing mounting screws 55 on the ceiling wall portion 63 of the storage box body. However, as shown in FIG. 6, the side wall portion of the storage box body 60 is The ceiling wall portion side 601 and the anti-ceiling wall portion side 602 are divided into two parts, and tongue-like joint portions 601a and 602a for joining the two portions are provided in the divided portions, and both the joint portions are screwed with mounting screws 56. You may make it the structure which stops and assembles.
According to this structure, since it is not necessary to fix the screw to the ceiling wall portion 63, the height of the screw head portion is unnecessary, so that the height of the control panel for the mounting screw head can be further reduced.

As shown in FIG. 7, the mounting screw 56 is not hidden by the mounting screw 54 when viewed from the front, that is, both (the screwing position for screwing the joint portions 601a and 602a and the screw of the storage box body). By disposing the stop position 602b) and allowing it to be screwed from the same direction (front side: arrow A direction in FIG. 6), the entire storage box 60 can be removed with the control panel door open. Since it can be carried out easily, assembly can be realized without impairing workability and maintenance workability.
This configuration also reduces the height of the control panel by eliminating the need for extra screw protrusions on the ceiling wall of the storage box without compromising the efficiency of the storage box mounting work during work or maintenance. Becomes even more possible. In addition, since the storage box containing the electromagnetic control device can be directly fixed to the fixing member of the control panel, the buffer member outside the conventional storage box can be eliminated and the workability is improved. To do.
