2. Description of the Related Art Partition doors are excellent in heat retention, dustproof and insect repellent effects because they can pass through necessary partitions without opening the entire door by pushing only the door open. It is often used as an entrance door and partition for warehouses.

FIG. 5 shows a conventional drive device for driving a partition door. The partition door described above hangs a large number of partition door sheets 102 that are cut into strips on a long-sized support member 101, and the support member 101 is attached to a guide rail 103 provided along the upper portion of the doorway 100. The partition sheet 102 is openably and closably supported by being slidably supported along the partition sheet 102.

The drive device 200 is for reciprocating the support member 101 along the guide rails 103, and the pulleys 2 provided at both ends of the guide rails 103, respectively.
The chain 203 is wound substantially endlessly between 01 and 202, and one end and the other end of the chain 203 are attached and fixed to the support member 101 via attachment members 204 and 205. A drive motor 206 is connected to the above-mentioned one pulley 202 via a drive belt 207, and an endless chain 203 is rotated by the drive rotation of the drive motor 206, and the support member 101 is pulled by the chain 203 to partition the partition. The door seat 102 is configured to move in the opening direction or the closing direction.

However, in the above-mentioned conventional drive mechanism 200, the chain 203 is endlessly hung between the two pulleys 201 and 202, and the two pulleys 201 and 201 are provided.
Since it is a method of opening and closing the partition door in the range of 02, at least two pulleys are required and
The space occupied by the pulleys 201 and 202 and the chain 203 becomes large, and the drive mechanism inevitably becomes large in size.

Therefore, in the case where a partition door which is manually opened and closed is already installed at the entrance and exit and the opening and closing drive is automatically performed by adding a drive unit to the existing partition door, it is constructed based on the above-mentioned driving method. When attempting to install a drive mechanism, it was often impossible to automate the opening and closing because space was not available.

An object of the present invention is to provide a method for driving a partition door in which the space occupied by the drive mechanism is reduced and the drive mechanism can be downsized, thereby obstructing the automation of the existing manual partition door in terms of space. It is to be able to do without causing.

[0009]

In order to achieve the above object, the present invention constructs a partition door by suspending a partition door sheet on a horizontally extending support material, and the support material is long at the upper part of the doorway. A method of driving a partition door that opens and closes an entrance and exit by slidably supporting in a vertical direction, wherein a transmission member such as a belt or a chain is additionally suspended between both ends of the support member, and the transmission member is provided. Is hung on the outer periphery of the upper part of the drive car mounted and supported by the fixed structural member at the upper part of the doorway, the drive car is driven and rotated in a predetermined direction by the drive motor, and the engagement position of the drive car with respect to the transmission member is shifted to fix the The transmission member and the supporting member are horizontally moved with respect to the driving vehicle, and the partition door is moved in the opening direction or the closing direction within the length of the supporting member, and the driving motor The limit switch controlling the operation is intended to stop the partition door in a predetermined closed and open positions.

[0010]

According to the above-mentioned means, the long support material for suspending the partition door sheet is supported horizontally at the upper part of the doorway and slides in the length direction. By this sliding, the partition door sheet suspended on the support material opens and closes the doorway. A transmission member such as a belt or a chain is additionally hung between both ends of the support member. And
The intermediate portion of the transmission member is hung around the outer periphery of the upper portion of the drive vehicle mounted and supported by the fixed structural member above the entrance and exit, and the drive vehicle and the transmission member are engaged with each other at the hung portion.

Therefore, when the drive wheel is driven and rotated in the predetermined direction by the drive motor, the engagement position between the drive wheel and the transmission member is relatively displaced, and the drive wheel is fixed to the fixed structural member. The transmission member and the supporting member slide horizontally to the left and right, whereby the partition door moves in the opening direction or the closing direction. Further, as described above, the partition door which moves horizontally is stopped at a predetermined closed position and open position by stopping the operation of the drive motor by the limit switch.

[0012]

As described above, according to the present invention, the transmission member is hung around the upper outer periphery of the drive wheel mounted and supported by the fixed structural member at the upper part of the entrance and exit, and the drive wheel is driven and rotated in the predetermined direction by the drive motor. By shifting the engagement position of the drive wheel with respect to the transmission member, the partition door is moved in the opening direction or the closing direction within the range of the length of the support member. Since only one is required, the structure of the drive mechanism can be significantly downsized and simplified as compared with the conventional case where a chain is stretched between two gears to open and close the partition door. It will be possible. In addition, even when automating a manual partition door that is already installed at the entrance / exit, it is possible to attach a drive mechanism to the partition door simply by additionally suspending a transmission member between both ends of the support member. Therefore, the existing manual type partition door can be easily modified as an automatic opening / closing type partition door without causing a space problem.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 show a drive device b for driving the partition door a.

The drive device b is, as shown in FIGS. 3 and 4,
The partition door a is provided above the doorway c provided on the partition wall of the room and horizontally reciprocates.

The partition door a is composed of a plurality of partition door sheets 2 formed by cutting a transparent resin sheet into strips.
It is configured by suspending the long-sized support member 1 extending in the horizontal direction at regular intervals, and the support member 1 is mounted along a guide rail 7 that is horizontally fixed to the wall surface above the doorway c. By being slidably supported, the entrance / exit c can be opened and closed by the partition door sheet 2.

The supporting member 1 is attached to the supporting member 1a made of a long-sized angle member whose one side edge is bent in a substantially U-shaped cross section, and the supporting member 1a in a state of being overlapped along the upper surface of the supporting member 1a. It is composed of a strip-shaped additional member 1b which is integrally fastened together with the support metal fitting 8a5. By screwing the upper end of the partition sheet 2 to the suspending metal fittings 2a attached to the support member 1 at regular intervals in the length direction, the partition sheets 2 are suspended as described above, and Traveling vehicles 8 are provided at regular intervals along the length direction. As described above, each traveling vehicle 8 is engaged so as to be able to travel along the guide rail 7 that is horizontally fixed and attached to the upper wall surface of the entrance / exit c.

The traveling vehicle 8 is constructed by pivotally supporting a total of four wheels 8b by a support shaft metal fitting 8a protruding in a T shape from the upper surface of the support member 1. Then, the traveling vehicles 8 attached in a line along the support material 1 are fitted in a guide rail 7 formed in a substantially U-shaped cross-section in a state capable of traveling.

The guide rail 7 is made of a long angle member having a substantially U-shaped cross section that opens downward, and the rail portion on which the wheels 8b of the traveling vehicle 8 travel by bending both edges of the opening inward. 7a is formed. An appropriate number of receiving fittings 7b are fitted on the outer periphery of the guide rail 7 at regular intervals in the length direction, and the receiving fittings 7b are connected to the entrance c.
It is attached and fixed to the upper wall surface by an anchor bolt or the like, whereby the guide rail 7 is horizontally attached and supported at the upper portion of the entrance / exit c. Therefore, the support material 1 for suspending the partition door seat 2 is suspended by the guide rail 7 via the traveling vehicle 8, and the traveling vehicle 8 travels along the inside of the guide rail 7 so that the guide rail 7 is supported. Slide along.

The partition door a has the same structure as an existing partition door which is manually opened and closed. That is,
The partition door a can be installed at the doorway c as well as newly installed. By the way, the above-mentioned supporting member 1a is originally provided as a supporting member in a manual partitioning door, and a strip-shaped additional member 1b is added to this supporting member (supporting member 1a).
The timing belt 5 which will be described later is suspended between the both ends of the support member 1 by attaching it later, whereby the manual partitioning door can be changed to an automatic opening and closing type that can be automatically opened and closed by the drive device b.

A timing belt 5 for driving is provided on the upper surface side of the above-mentioned supporting member 1 with its tooth surface facing downward, and an intermediate portion thereof is pivotally supported by the output shaft 3 of the drive motor 30. It is hung around. The drive motor 30 is
The output shaft 3 mounted and supported on the side surface of the support plate 9 having an L-shaped cross section, which is mounted and fixed to the upper wall of the entrance / exit c, is projected horizontally to the inside of the support plate 9 toward the guide rail 7 directly above the support member 1. It has been extended.

A timing pulley 4 is attached to the output shaft 3 of the drive motor 30, and the above-mentioned timing belt 5 is wound around the outer periphery of the upper half portion of the timing pulley 4 in an inverted U-shape so as to mesh with it. An auxiliary pulley 10 pivotally supported by a support plate 9 is provided on both sides of the timing pulley 4 in such a manner that a bent portion of the timing pulley 4 is pushed from the outside, and the timing belt 5 is inverted U-shaped by the both auxiliary pulleys 10. It is wound around the outer periphery of the upper half of the timing pulley 4 in a bent state so that the timing belt 5 and the timing pulley 4 can be meshed with each other reliably.

Further, both ends of the timing belt 5 are fixed to both ends of the supporting member 1 in a state where appropriate tension is applied. Therefore, the other parts of the timing belt 5 except the part wound around the timing pulley 4 maintain the state in which the tooth surface is attached to the upper surface of the support material 1.

In the above drive device b, since the timing belt 5 which is lightweight and has high transmission efficiency is used as the transmission member, the capacity of the drive motor 30 is larger than that when a chain or V belt is used as the transmission member. Can be made smaller. As the transmission member, a chain, a V-belt or the like may be used in addition to the timing belt. In this case, instead of the timing pulley 4, a sprocket or a V-belt may be used.
A belt pulley or the like will be used.

The drive of the drive motor 30 described above, that is, the opening and closing of the partition door a is performed by a switch d provided near the doorway c. Further, as shown in FIG. 3, limit switches 11 and 12 are provided on both sides of the support plate 9 that supports the timing pulley 4 and the drive motor 30. The limit switches 11 and 12 control the stop of the drive motor 30, and the partition door a that slides along the guide rail 7 by the motor 30 is moved to the fully opened position shown in FIG. 3 and the fully opened position shown in FIG. It is for stopping at the closed position, and each is incorporated in a drive circuit (not shown) of the drive motor 30.

Both limit switches 11 and 12 are mounted on the motor mounting surface of the support plate 9 as shown in FIG. 1. In FIG. 3, the limit switch 11 for fully open stop is on the right side of the support plate 9 and the limit for fully closed stop. The switch 12 is arranged on the left side of the support plate 9. Both limit switches 1 like this
Since the electric systems related to the drive motor 30 can be concentrated on the support plate 9 by mounting the support plates 9 and 12 on the support plate 9, electric wiring can be completed at the same time when the support plate 9 is installed.

On the other hand, one end of the support member 1 has a partition door a.
Limit switch 1 above when is moved to the fully open position
1 is provided with a protrusion 13 that makes the switch 11 off by making contact with the contact of the limit switch 12, and the other end of the support member 1 contacts the contact of the limit switch 12 with the partition door a moved to the fully closed position. A protrusion 14 for turning off the switch 12 is provided. That is, when the partition door a moves to the fully open position or the fully closed position by the drive of the drive motor 30, the projections 13 and 14 come into contact with the limit switches 11 and 12 to stop the drive motor 30 and stop there. It will be.

Next, the drive device b constructed as described above.
The opening / closing operation of the partition door performed by the above will be described.
When the drive motor 30 is driven and rotated in the closing direction by the switch d provided near the doorway c, the timing pulley 4 rotates clockwise in FIG.
The meshing position of the timing pulley 4 with respect to is shifted to the left. As a result, the timing belt 5 is pulled rightward, and the support member 1 slides rightward along the guide rail 7 in opposition to the timing pulley 4 fixed to the wall surface above the entrance / exit c, and is supported. The drive motor 30 stops when the projection 14 at the end of the material 1 contacts the limit switch 12. As a result, the entrance / exit c is closed by the partition door a as shown in FIG.

When the drive motor 30 is driven and rotated in the opening direction by operating the switch d, the timing belt 5 is pulled leftward, and the support member 1 faces the timing pulley 4 leftward along the guide rail 7. When the projection 13 at the end of the support member 1 comes into contact with the limit switch 11, the drive motor 30 is stopped, and the partition door a that was closing the doorway c as shown in FIG. Open.

The limit switches 11 and 12 described above are used.
Although a contact switch that is turned on / off by the contact of the protrusions 13 and 14 is used for the above, a switch that is turned on / off by a sensor such as an optical sensor may be used as the limit switch.
