Description

  The present invention relates to a transfer apparatus capable of dealing with a division between rooms and between buildings by a blocking wall such as a fire shutter in a transfer facility in which a transfer object is movably arranged between rooms in a building and between buildings. It relates to the shut-off mechanism.

  In recent years, buildings such as three-dimensional automated warehouses, distribution centers and factories equipped with transportation equipment and manufacturing equipment have a large total floor space and many sealed spaces with few windows. Since it led to a fire and had a great influence not only on buildings but also on neighboring residents, the countermeasures have become very important.

  Fire prevention measures are taken at each stage, from prevention to firefighting activities, but the Fire Services Act and Building Standard Act play a role in causing buildings to take various measures. The Fire Service Act is assigned to countermeasures at the initial stage of fire, and the Building Standard Law is assigned to countermeasures in case the initial fire extinguishing stage of fire prevention equipment, evacuation routes, emergency facilities, etc. is broken.

  In particular, the Building Standard Law prevents fires from spreading and secures evacuation routes, as well as assists in fire fighting and rescue activities, depending on the size, type, use, etc. of the building. And division method is established (Building Standard Act enforcement order Article 112).

For example, in a fire-resistant structure with a floor area exceeding 1,500 m ² , it is obliged to divide it with a semi-fire-resistant floor or wall or specific fire prevention equipment every 1,500 m ² or more. Fire shutters and the like need to be provided between the building rooms.

  Fig. 1 shows a fire barrier as a barrier that can be divided into rooms by installing transport equipment that can be moved freely between rooms in a building, such as a three-dimensional automatic warehouse or a distribution center. The schematic diagram in the building which provided the shutter was shown. As shown in FIG. 1, rooms 1-1 and 1-2 partitioned in a building having a size larger than a prescribed size are provided with a quasi-fireproof fireproof shutter 2-1 on the wall 1-3 of the building, Fire prevention equipment provided with the guide rail 2-2, the sensor 2-3, the automatic switch 2-4, etc., and capable of dividing the transfer devices 1-4, 1-5 deployed in different rooms in the event of a fire It has become. And between the conveying devices 1-4 and 1-5 deployed across the fire prevention equipment, a relay conveying device 1-6 that can normally deliver and move a conveyed item freely between rooms is installed. However, in order to avoid the obstacle of the fire prevention shutter 2-1 that descends at the time of a fire, some contrivance is provided for retracting the relay transfer device 1-6.

  For example, Patent Document 1 discloses a transport unit, a guide for preventing a fall of a transported object, a fitting as a retracting mechanism for a relay member that delivers a transported object between transport apparatuses in different rooms and does not become an obstacle to a falling barrier. It is held at the transported object delivery position by a mating tool holder equipped with a coupling and a compression spring and a sphere, and collides with a guide that prevents the transported article from falling on the lowering barrier wall, and the fitted and held state is released. In addition, a mechanism is described in which the transport unit rotates by its own weight and moves to the retracted position.

  In this example, it is described that the blocking wall that descends collides with a guide that prevents the fall of the transported object that constitutes the relay member, thereby avoiding a collision with the transport unit and protecting the transport unit. In the event of a fire that requires sexuality, the fire-resistant and heavy barrier wall descends at a high speed and closes the room, so that it will still collide violently with the guide. Further, since the relay member is held by the fitting of the fitting provided on the relay member and the fitting holder provided with the compression spring and the sphere, the heavy barrier wall that descends at high speed collides with the guide. The impact at the time is extremely large, and the damage to the relay member is considered to be beyond imagination. In addition, such mechanical fitting and evacuation due to its own weight is not guaranteed to work reliably. In addition, a mechanism for quickly restoring the transport facility is not provided, and it is necessary to rely on human power. After the fire is over, in order to quickly restore the transport equipment, and also considering the malfunction of the shutoff wall due to the increased sensitivity of the fire detector, the transport equipment is easily, preferably as the shutoff wall opens and returns. It is desirable to be restored automatically.

  In addition to the above, various relaying mechanisms have been proposed to prevent the intermediate transfer device that delivers the object between the transfer devices in different rooms from being a hindrance to the falling barrier, but the heavy barrier is lowered at high speed. Therefore, the relay transport device can be operated without damaging the relay transport device, and the relay transport device can be quickly restored, that is, the transported object moves between rooms in the building and between buildings. Freely deployed transportation equipment can be quickly and safely restored without any damage to the transportation equipment when it is divided between rooms and buildings by barriers such as fire shutters. A possible transfer device blocking mechanism has not yet been found.

JP-A-10-59521

  The present invention relates to fire prevention equipment that has been enhanced by the social background of preventing the expansion of fire damage accompanying the increase in the scale of buildings such as three-dimensional automatic warehouses and distribution centers equipped with transport facilities, particularly in buildings. In the fire prevention equipment that divides the room and the building by the barrier wall such as fire prevention shutter of the transfer equipment in which the transfer object is movably arranged between the rooms and between the buildings, without damaging the transfer equipment, The objective is to provide a transport device shut-off mechanism that is safe, secure, reliable, and can be quickly restored.

  More specifically, the relay transfer device that transfers the transported objects installed between the transfer devices in different rooms that require fire prevention equipment to divide between rooms and buildings by means of a barrier wall such as a fire shutter is shut off. An object of the present invention is to provide a blocking mechanism for a transport device that can be quickly and reliably retracted without being damaged with respect to the closing of the wall, and that can be quickly restored when the blocking wall is opened.

  The present invention basically includes a relay transfer device that includes a means for detecting the lowering of the barrier wall, and is installed between the transfer devices in different rooms by a signal or power of the detection means. The blocking mechanism is configured to include a driving device or an operating component that can be retracted from the blocking space where the blocking wall descends. However, the detection unit, the relay transfer device, and the blocking of the transfer device characterized by the operating component, respectively. Mechanism.

  For the detection means, the material and configuration of the lever or roller that contacts or collides with the blocking wall, for the relay transport device, a mechanism that rotates, slides, or expands and contracts, and for the drive device, the cylinder and its As for the power source and the like, with respect to the operating parts, the combination of a spring, a weight, a pulley, and the like, and the holding parts and holding method of the relay conveyance device have been studied, thereby completing the present invention.

  That is, the present invention relates to a transport facility capable of moving a transported object between rooms, a transport device having a start / end position between the rooms, and a relay transport unit positioned in a shut-off space in which a barrier wall between the rooms moves up and down. , A detecting means for detecting a blocking operation of the barrier wall, and a double-acting means capable of stopping and driving the relay conveying means, wherein the relay conveying means is a conveyor that is responsive to the conveying device, and is the start or end of the conveying device It is supported by one end of the rotation side plate supported around the rotation axis of the rotation side plate support member provided in the vicinity, and the double-acting means can support the conveyor responding to the conveying device and from the blocking space. It is a blocking mechanism for a transfer device, characterized in that it is connected to a rotating side plate so that it can be rotated and retracted.

  The conveyor that responds to the transfer device applied as the relay transfer means is not particularly limited, and the transfer object can be delivered between the rooms without hindrance, and fits in the blocking space where the blocking wall can be raised and lowered. Any general roller conveyor, belt conveyor, or the like is suitable. In the case of a roller conveyor, it is preferable that there is only one roller that can construct a simple blocking mechanism.

  A pivoting side plate that supports the pivoting side plate and supports the pivoting side plate and is retractably connected from the blocking space while pivotally supporting the relay conveying means and pivoting from the blocking space to be retractable. The moving means may be installed on at least one of the two transfer devices whose start and end positions are located between the rooms, but the function of delivering the transfer material of the relay transfer device and the function of retracting the relay transfer device are stable. Therefore, it is preferable to install on both sides.

  A rotating side plate support member that rotatably supports the rotating side plate that pivotally supports the conveyor may be specially provided, but may be replaced by a side wall of the transport device. Similarly, a support member that fixes the detection unit and the double-action unit may be newly provided, or may be fixed by using the side wall of the transport device.

  Such a blocking mechanism of the transfer device supports the relay transfer means and pivots the rotating side plate support member when a signal is issued from the detection means that detects the blocking operation that the blocking wall descends and closes the room. The double-acting means connected to the pivoting side plate supported around the shaft operates to pivot the pivoting side plate downward to retract the relay conveying means from the blocking space. Conversely, when the detection means detects a connection operation in which the blocking wall rises and opens the room, a switching signal is issued, and the double-action means rotates the rotating side plate upward to move the relay conveying means to the original. It can be returned to the position.

  Therefore, the blocking mechanism of the transfer device according to the present invention includes a double-action unit in which the relay transfer device is rotatably connected based on a signal transmitted from the detection unit without contact between the blocking wall and the relay transfer device. Since the relay transport device can be retracted from the shut-off space by operating, the relay transport device can be retracted reliably and promptly without being damaged, and can be promptly restored when the shut-off wall is opened.

  Furthermore, the blocking mechanism of the transport apparatus according to the present invention is characterized in that the following relay transport means is applied from the viewpoint of reliable and quick evacuation and quick return.

  First, a transport device in which the start and end points are located between rooms, a relay transport unit located in a shut-off space in which a barrier wall between rooms rises and lowers, a detection unit that detects a shut-off operation of the shut-off wall, and a relay transport unit In the shut-off mechanism of the transport device provided with stationary and drivable double-action means, the relay transport means is a conveyor that responds to the transport device, and is provided outside the shut-off space adjacent to the beginning or end of the transport device. Conveyor sliding is supported by a sliding support member that slides on the sliding member, and the double-acting means can slide the sliding support member and slide away from the blocking space. It is connected to a support member.

  Also in this case, the conveyor that responds to the transport device applied as the relay transport means is not particularly limited, and the transported object can be delivered between the rooms without hindrance, and the barrier wall can be raised and lowered. Any material can be used as long as it can fit in the blocking space, and a general roller conveyor, belt conveyor, or the like is suitable. In the case of a roller conveyor, it is preferable that there is only one roller that can construct a simple blocking mechanism.

  Further, a sliding member provided outside the blocking space adjacent to the beginning or end of the conveying device, a conveyor sliding support member that pivotally supports the conveyor and slides on the sliding member, and the conveyor sliding support member are slid. The double-acting means that can be stopped and slidably connected from the shut-off space may be installed on at least one side of either of the two transfer devices in which the start and end positions are located between the rooms. In order for the function of delivering the conveyed product of the apparatus and the function of retracting the relay conveying apparatus to be expressed stably, it is preferable that the apparatus is installed on both sides.

  The sliding member that receives the double-action means and the conveyor sliding support member may be fixed by providing a new support member, or may be fixed by using the side wall of the transport device.

  Such a blocking mechanism of the transfer device is provided outside the blocking space adjacent to the start or end of the transfer device when a signal is emitted from the detection means that detects the blocking operation in which the blocking wall descends and closes the room. When the double-acting means connected to the conveyor sliding support member that slides on the sliding member and pivotally supports the relay conveying means is retracted, the conveyor sliding support member slides and the relay conveying means is shut off. Operates to escape from space. Conversely, when the detection means detects a connection operation in which the blocking wall rises and opens the room, a switching signal is issued and the double-action means expands, causing the conveyor slide support member to slide and relay. The conveying means can be returned to the original position.

  Secondly, a transport device having a start / end position between rooms, a relay transport unit positioned in a blocking space in which a blocking wall between rooms rises and lowers, a detection unit that detects a blocking operation of the blocking wall, and a relay transfer unit In a shut-off mechanism of a transport device having a stationary and drivable double-action means, the relay transport means is a conveyor that is responsive to the transport device, and is a conveyor fixed support outside the shut-off space adjacent to the beginning or end of the transport device One end of the conveyor that responds to the transport device is pivotally supported by the member, and the double-acting means is connected to the other end of the conveyor that responds to the transport device so that it can be supported and rotated from the shut-off space. It is characterized by.

  As the conveyor, a general roller conveyor, a belt conveyor, and the like are suitable. However, in this case, the roller conveyor cannot save the relay conveyance means from the blocking space with one roller, so at least two or more rollers are used. It must be a conveyor with

  When a signal is emitted from the detection means that detects the blocking operation that the blocking wall descends and closes the room, the blocking mechanism of the transfer device is attached to the conveyor fixing support member outside the blocking space adjacent to the start or end of the transfer device. The double-acting means connected to the other end of the relay conveying means whose one end is pivotally supported is retracted, and the relay conveying means is rotated downward to be retracted from the blocking space. Conversely, when the detecting means detects a connection operation in which the blocking wall rises and opens the room, a switching signal is issued and the double-action means expands to return the relay transport means to the original position. Can do.

  In addition, since it is the same as that of the said interruption | blocking mechanism about the installation method and installation place of a conveyor fixed support member and a double acting means, description is abbreviate | omitted.

  Thirdly, a transfer device having the start and end positions between the rooms, a relay transfer means positioned in the blocking space in which the blocking walls between the rooms move up and down, a detection means for detecting the blocking operation of the blocking walls, and a relay transfer means In the shutoff mechanism of the transport device provided with stationary and drivable double-action means, the relay transport means is a conveyor that responds to the transport device and is supported by a conveyor telescopic support member provided near the beginning or end of the transport device In addition, the double-acting means is connected to the conveyor expansion / contraction support member so as to be able to hold the conveyor responsive to the conveying device and to retract from the blocking space.

  In this case, a general belt conveyor or roller conveyor cannot be applied as a conveyor as a relay conveying means, and a spring or the like expands and contracts between support members that pivotally support at least two or more rollers constituting the conveyor. It is necessary to connect the double-acting means so that the means can be provided and the telescopic means can be retracted and the conveyor can be held.

  With such a configuration, when a signal is issued from the detecting means that detects the shut-off operation in which the shut-off wall descends and closes the room, the double-acting means degenerates, so that the rollers that constitute the relay transport means The expansion / contraction means between the supporting members that support the shaft is retracted, the length of the conveyor is shortened, and the relay conveyance means can be retracted from the blocking space. Conversely, when the detection means detects a connection operation in which the blocking wall rises to open the room, a switching signal is issued and the double-action means expands to support the rollers constituting the relay conveyance means. The expansion / contraction means between the support members is also extended, the length of the conveyor is increased, and the relay conveyance means can be returned to the original position.

  In addition, since it is the same as that of the said interruption | blocking mechanism about the installation method and installation place of a conveyor fixed support member and a double acting means, description is abbreviate | omitted.

  Fourth, a transport device having a start / end position between rooms, a relay transport means positioned in a shut-off space in which the barrier walls between the rooms move up and down, a detection means for detecting the shut-off action of the shut-off walls, and a relay transport means In the interrupting mechanism of the transport device provided with the stationary and drivable double-action means, the relay transport means is a roller that responds to the transport device, and the roller that responds to the transport device is pivotally supported by the roller rotation support member. In addition, the roller rotation support member is pivotally supported by using a spherical bearing provided in the spherical bearing support member near the beginning or end of the conveying device, and further, the roller rotation support member is slidably contacted from the blocking space. It is provided with a guide plate, and the double-acting means is connected to the roller-rotating support member so as to be able to support the roller that responds to the conveying device and to be able to retreat horizontally from the blocking space in the vertical direction. Features and Is shall.

  In this case, the relay conveying means is limited to one roller. The L-shaped roller rotation support member on which the roller is pivotally supported is supported by a spherical bearing, and the double-action means is connected to the arm of the L-shaped roller rotation support member so that the double-action means can be extended and A guide plate for guiding the roller to a path that allows the roller to retract from the blocking space and return to the blocking space as it retracts is in slidable contact with the arm of the L-shaped roller rotation support member.

  The roller trajectory by the guide plate of the blocking mechanism having this configuration will be described in more detail. Since the L-shaped roller rotation shaft support member is supported by a spherical bearing, the L-shaped roller rotation shaft support member can move three-dimensionally. Therefore, when the double-acting means connected to the arm of the L-shaped roller rotation shaft support member is extended, the roller supported by the L-shaped roller rotation shaft support member is moved from the transport device installed in a different room. If the guide plate has a shape that pivots upward from the position and the double-action means expands and retracts in a direction perpendicular to the conveying device, the double-action means can be converted into a rotational movement of the roller. It is possible to easily return from the blocking space to the evacuation and blocking space.

  In the case of this shut-off mechanism, the spherical bearing support member, the L-shaped roller rotating shaft support member, and the installation method and location of the double-acting means are different from the shut-off mechanism described above, and the spherical bearing support member and double-acting means are The L-shaped roller rotating shaft support member is naturally provided on one side of the roller of the relay conveying means.

  Fifth, a transfer device in which the start and end are located between the rooms, a relay transfer means positioned in the blocking space where the blocking walls between the rooms are raised, a detection means for detecting the blocking operation of the blocking walls, and a relay transfer means In the interrupting mechanism of the transport device provided with stationary and drivable double action means, a step is provided at the start and end of the transport device, and the relay transport means is a conveyor or an inclined plate that responds to the transport device, and the step is relayed. The conveyor fixing support member or the inclined plate fixing support member outside the blocking space adjacent to the beginning or end of the conveying device is supported at one end of the conveyor or the inclined plate that responds to the conveying device, and the double acting means is It is characterized in that it is connected to a conveyor or an inclined plate that responds to the conveying device so that the conveyor or inclined plate that responds to the conveying device can be pressed and can be retracted by rotating from the blocking space.

  As the conveyor in this case, a general roller conveyor, belt conveyor, or the like can be applied, and the conveyor fixing support member or the inclined plate fixing support member and the double-action means for supporting these are installed on at least one side of the transport device. However, it is preferable to provide it on both sides of the transporting device in order to ensure a stable conveyor or slanting plate retracting and returning. Moreover, although the method of fixing this may provide a new support member, the side wall etc. of a conveying apparatus can be utilized.

  Further, the blocking mechanism of the transport device of the present invention provides the following solution means for the purpose of retracting the relay transport means reliably and promptly and also quickly returning the double-acting means. Yes.

  First, the double-acting means is an air cylinder and an electric cylinder that reciprocates the piston so that the relay conveying means is retracted from the blocking space and the relay conveying means is returned to the blocking space in accordance with an instruction from the detecting means. It is what.

  Air cylinders are powered by compressed air, so they have a simple structure, small size, high safety and clean equipment. They can be used in high-temperature environments and are suitable for double-acting means that are driven in a fire. ing. Further, since the compressed air is elastic, the possibility of damaging the relay transport means is reduced when the relay transport means according to the present invention is retracted and restored.

  The air supply switching valve of the air cylinder includes a pneumatic switching valve and an electromagnetic switching valve, but is not particularly limited. From the viewpoint of not using electricity, a pneumatic switching valve is preferable, and a device using a full pneumatic circuit is possible. However, since the problem of the power source can be solved by applying an emergency power source or a self-power generating device as will be described later, it is desirable to use both in consideration of the switching speed.

  And as an air supply means to the air cylinder, an air tank for storing high-pressure air connected to a compressor via an on-off valve is provided, so that only in the event of a fire, as in the shut-off mechanism of the transport device of the present invention. In the case of using it for the purpose, there is a feature that it is not necessary to enlarge the apparatus. Furthermore, in order to cope with a failure of the main air tank, it is preferable to provide an auxiliary tank via an on-off valve, and it is even more preferable to provide an auxiliary tank connected to the compressor via the on-off valve. In the worst case, the air supply means to the air cylinder should be operated sufficiently with the air piping formed by the air cylinder and the on-off valve, since the shutoff mechanism of the transport device of the present invention is used only in the event of a fire. Is also possible. Thus, the air cylinder is particularly excellent from the viewpoint of safety.

  On the other hand, the double-acting means of the blocking mechanism of the transfer device of the present invention is an electric cylinder because it has characteristics different from those of an air cylinder.

  In particular, the electric cylinder has a great feature that it has excellent controllability, the position and speed can be easily adjusted, and the initial movement is fast. Therefore, the high controllability can prevent damage, and the speed of the initial movement is suitable for the evacuation of the relay conveying means requiring urgency.

  The need for a power supply can be solved by applying an emergency power supply or a self-power generation device, as will be described later.

  Secondly, the double-acting means of the present invention is an air cylinder or an electric cylinder that reciprocates the piston so that the relay conveying means is retracted from the blocking space and the relay conveying means is returned to the blocking space according to the instruction of the detecting means. It is a mechanism in which mechanical expansion and contraction devices are arranged side by side.

  In this way, by arranging the mechanical expansion and contraction device in parallel with the air cylinder or the electric cylinder, it assists the reciprocating motion of the pinstone of the air cylinder or the electric cylinder, and only reduces the load of the power source related to the air cylinder or the electric cylinder. Instead, it controls the operation of the relay conveying means.

  Although it does not specifically limit as a mechanical expansion-contraction apparatus, It is preferable that they are a wire with a weight, a compression spring, and a tension spring. In the case of a wire with a weight, the relay transport means is urged to operate quickly when the relay transport means is retracted. In the case of the compression spring, the holding of the relay transfer device that delivers the transfer device in a different room is assisted, and elasticity is given to the operation of the relay transfer device in the evacuation to prevent damage to the relay transfer device. And in the case of a tension spring, like a wire with a weight, it prompts the relay conveying means to operate quickly.

  Further, in a transport facility capable of moving a transported object between rooms, a transport device having a start / end position between the rooms, a relay transport means positioned in a blocking space where the blocking wall between the rooms moves up and down, and a blocking wall As a feature of the shut-off mechanism of the transport apparatus of the present invention, which includes a detecting means for detecting the shut-off operation, and a double-acting means capable of stopping and driving the relay transport means, a detecting means can be mentioned.

  The detection means of the present invention includes a lever that is located in the blocking space and contacts or collides with the blocking wall as the blocking wall descends, a switching device that converts the displacement of the lever into a signal, Or it has the wiring which transmits to a conveying apparatus.

  By providing the detection means of the present invention, it is possible to shift to the retracting operation of the relay transport means without contact or collision between the blocking wall and the relay transport means, so that it is possible to suppress damage to the relay transport means. Depending on the position of the lever of the detecting means, it is possible to shift to the retracting operation of the relay conveying means and to stop the conveying apparatus. It is also possible to prevent the transported item from falling.

  On the contrary, after the fire is extinguished or the blocking wall malfunctions, the blocking wall rises and the signal is switched by the lever of the detection means, and the relay transfer means moves the transfer object between transfer devices in different rooms. It can be returned to the original position for delivery.

  Furthermore, such a detecting means can induce a retracting operation and a returning operation of the relay conveying means that does not require a power source by devising a lever that contacts or collides with the blocking wall as the blocking wall descends and rises. it can. That is, the detection means is a wheel-shaped power generation roller that rotates in contact with the blocking wall and is pivotally supported by a first detection roller support member fixed near the beginning or end of the transport device, and is provided with an amplifier. It is connected to an electric power generator in a rotatable manner, and is wired with an air cylinder, and is used as a power source for driving an electromagnetic switching valve of the air cylinder. This detecting means has a feature that the air cylinder can be driven and the relay conveying means can be retracted and returned without requiring any power source. It can also be a power source when an electric cylinder is used.

  On the other hand, when the shut-off mechanism of the transport device of the present invention uses an air cylinder or an electric cylinder as the double-acting means for retracting the relay transport means, the detecting means need not be a lever that contacts or collides with the shut-off wall, It may be a fire alarm and / or a sprinkler. Since the fire alarm and / or sprinkler signal is transmitted to the double-acting means and / or the transport device, it is possible to shift to the retracting operation of the relay transport device and to stop the transport device. It is possible not only to quickly save the conveying means but also to prevent the conveyed object from dropping from the conveying device.

  As described above, when double acting means that requires a power source, such as an air cylinder or an electric cylinder, is used in the interrupting mechanism of the transport device of the present invention, a power failure is expected in the event of a fire. It is preferable to be able to switch.

  In this way, in a transport facility capable of moving a transported object between rooms, a transport device having a start / end position between rooms, a relay transport unit positioned in a shut-off space in which a barrier wall between the rooms moves up and down, and a shut-off Although the relay conveying means and the detecting means have been described as the features of the blocking mechanism of the conveying apparatus of the present invention, comprising the detecting means for detecting the wall blocking operation and the double acting means capable of stationary and driving the relay conveying means. Furthermore, the solution means which combined the detection means and the double action means was found.

  The conventional double-acting means used to retract and return the relay conveying means by utilizing the reciprocating motion of the piston of the cylinder using water, air, oil, electricity, etc. as the power source. The double-acting means of the present invention shown is characterized in that the double-acting means capable of moving in a state where an applied pressure is applied during reciprocating motion without using a power source such as air or electricity is applied. There is.

  That is, the blocking mechanism of the transfer device according to the present invention is a transfer facility in which transfer objects can be moved between rooms. A relay conveying means located; a detecting means for detecting a blocking operation of the blocking wall; and a double-acting means capable of stationary and driving the relay conveying means, wherein the relay conveying means is a conveyor responsive to the conveying device, It is pivotally supported by a conveyor sliding support member that slides on a sliding member provided outside the blocking space adjacent to the beginning or end of the transport device, the double-acting means is a tension spring, and the conveyor slide supports by a stopper A winding device having a lever that is connected to a conveyor sliding support member so that the member can slide and retract from the blocking space and can be retracted, and the detection means includes a lever located in the blocking space, the stopper And winding device , The blocking wall is characterized in that the contact or collision with the stopper is releasably connected to the lever. A weight can be used instead of the tension spring.

  Since this relay mechanism is retracted by the detection means coming into contact with or colliding with the barrier wall, the relay transport means is not damaged, and the spring or weight is used as the power source. This is a high-security shut-off mechanism by the relay operation of the relay conveying means. Also, it does not require a power source and is suitable as a device that operates in the event of a fire.

  As described above, in a transport facility capable of moving a transported object between rooms, a transport device having a start / end position between the rooms, a relay transport unit positioned in a blocking space where the blocking wall between the rooms moves up and down, and a blocking wall The blocking mechanism of the transfer apparatus provided with the detecting means for detecting the blocking operation and the double-action means capable of stopping and driving the relay transfer means has been described. However, the realization of a shut-off mechanism that is the subject of the present invention, that is not damaged to the transport facility due to the lowering of the shut-off wall, that is safe, secure, and can be reliably handled, and that can be quickly restored is such a configuration. However, the present invention can be realized by a shut-off mechanism that does not require a power source and is characterized by combining various parts.

  As a blocking mechanism for such a transfer apparatus of the present invention, first, in a transfer facility capable of moving a transfer object between rooms, the transfer apparatus whose start and end are located between the rooms and the blocking wall between the rooms are raised and lowered. A relay conveying means located in the blocking space, a locking means capable of stopping the relay conveying means, and a detecting means for detecting a blocking wall blocking operation, and a detecting means for detecting the blocking wall blocking operation and the relay conveying. The intermediate transfer means release arm is integrated with the locking means that can be stopped, and the intermediate transfer means release arm is supported around the axis of the support column provided near the start or end of the transfer device. Is a roller that responds to the conveying device, and is provided at one end of the rotating side plate provided with a suspension pin that is supported with the rotating shaft of the rotating side plate supporting member provided near the start or end of the conveying device as a fulcrum. Supported and suspended by locking means With Jisuru hanging the turning plate using a pin, detection means, it is possible to increase the cut-off mechanism of the transfer device which is a switching device including a lever located on the shut-off space. In this blocking mechanism, the blocking means comes into contact with or collides with the lever due to the lowering of the blocking wall, and the latching means releases the suspension of the rotating side plate so that the relay means is retracted.

  According to this blocking mechanism, the relay conveyance means can be withdrawn promptly with a very simple structure without contact or collision between the blocking wall and the relay conveyance means. Conversely, since it has a simple structure, it is not automatic, but it can be easily recovered.

  By attaching a bearing to the suspension pin of this shut-off mechanism, the retracting operation of the relay conveying means can be made smoother, which is preferable. On the contrary, the relay conveyance means is stably held by connecting the lever, which is the detection means, and the column provided near the start or end of the conveyance device with a tension spring.

  A second shut-off mechanism that does not require a power supply and is characterized by combining various parts. An apparatus, relay transfer means located in the blocking space where the blocking wall between the rooms is raised and lowered, locking means capable of stopping the relay transfer means, and detection means for detecting the blocking action of the blocking wall. A relay conveying means retracting arm in which the detecting means for detecting the blocking operation and the relay conveying means are integrated, and the relay conveying means is a roller that responds to the conveying device and is pivotally supported at the tip of the relay conveying means retracting arm. The relay conveying means retracting arm is supported around the axis of the support column provided near the beginning or end of the conveying apparatus, and the locking means is a compression spring, which is fixed to the conveying apparatus and is connected to the relay conveying means retracting arm. Press and inspect It means, it is possible to increase the cut-off mechanism of the transfer device which is a switching device including a lever located on the shut-off space. According to this shut-off mechanism, the relay means retracts when the shut-off wall comes into contact with or collides with the lever due to the lowering of the shut-off wall and the locking means retracts.

  This second blocking mechanism also has an extremely simple structure, and the relay conveying means can quickly retract without contact or collision between the blocking wall and the relay conveying means, and the relay conveying means is pressed by the compression spring. Therefore, since the relay conveyance means does not fall freely, it has a feature that it is safe for workers and does not damage the conveyance device.

  Although it is a simple structure, it is not automatic but can be easily restored. In the case of this second blocking mechanism, the blocking wall is devised by devising the lever of the detecting means as described later. It is possible to automatically return the relay transport means as the speed increases.

  Although various types of blocking mechanisms have been described that solve the problems of the present invention, there are various problem-solving means of the present invention common to these. These are the materials and configurations of the levers used as detection means, to alleviate the impact and damage of the barrier and barrier mechanism, and to facilitate the restoration of the transport equipment when opening the barrier. It is intended.

  Even when the lever located in the blocking space provided in the detecting means is displaced by contact or collision with the falling blocking wall, the electrical signal starts the retracting operation of the relay conveying means. Even when the general operation starts the retracting operation of the relay conveyance means, if the lever is at least an elastic structure, the lever can be displaced to function the blocking mechanism of the present invention.

  However, the impact of the barrier wall and the lever that are received by the fire-resistant and heavy barrier wall descending at high speed and contacting or colliding with the lever is extremely large, and it is expected that the barrier wall and the lever will be damaged. The Therefore, it is preferable that the lever of the elastic structure located in the blocking space provided in the detection means is covered with a rubber-like substance or confined in a rubber balloon in order to reduce the impact. Further, it is more preferable that the lever itself is formed of a rubber-like substance having an elastic modulus that does not impair the displacement of the lever due to contact or collision with the blocking wall. Even when the lever made of such a material is displaced by contact with or colliding with the descending barrier wall, even when an electrical signal starts the retracting operation of the relay transport means, the mechanical operation Needless to say, even when the retracting operation of the relay conveying means is started, the blocking mechanism of the present invention can function by displacing like the lever of the elastic structure. Further, since the contact state can be maintained even after the barrier wall is lowered, the frictional force between the barrier wall and the lever causes an electrical signal or mechanical signal of the lever in the return of the relay conveying means accompanying the rising of the barrier wall. The operation can be switched in reverse, and the return of the relay conveying means can be semi-automated or automated.

  As a result of examining not only the material of the lever but also the structure of the lever, the following modifications made it possible to obtain a more favorable result than the lever with an improved elastic structure and material without damaging the original function of the lever. As a result, the present invention was completed.

  A first feature of the lever is that the roller is pivotally supported at the tip of the lever so as to come into contact with the descending blocking wall. Since the roller is displaced while rotating in contact with the descending blocking wall, the impact received by the blocking wall and the lever is further alleviated. At this time, a roller coated with a rubber-like substance or a roller made of a rubber-like substance is more preferable in order to facilitate rotation in contact with the blocking wall and to further reduce the impact. The lever on which the roller is pivotally supported not only relieves the impact, but as described above, the roller that maintains contact with the blocking wall can semi-automate or automate the return of the relay conveying means when the blocking wall rises. Can do.

  Secondly, in the detection means, the lever located in the blocking space is provided with a columnar part that contacts or collides with the lower end of the descending blocking wall and expands and contracts in the cylindrical part. is there. As a method for expanding and contracting the columnar part, a method of holding the columnar part by a compression spring provided in the cylindrical part or a method of holding by a compressed gas in a sealed space formed by the cylindrical part and the columnar part is simple and preferable. . Like the roller material, the tip of the columnar part is preferably a columnar part coated with a rubbery substance or a columnar part formed of a rubbery substance. The lever on which the columnar part expands and contracts not only relieves the impact, but also plays an important role in semi-automating or automating the return of the relay conveying means as the blocking wall rises as described above.

  Furthermore, in addition to the material and configuration of the lever, the problem-solving means of the present invention can also be provided by using a blocking mechanism of the transport device including a blocking wall having features.

  That is, near the lower end of the barrier wall, a lever that constitutes the detection means by lowering the barrier wall, a lever that pivotally supports the roller, or a protrusion at a position that contacts or collides with a columnar part, more preferably a rubber-like member The blocking mechanism includes a protrusion blocking wall to which a protrusion formed of a substance is attached. By adopting such a configuration, direct contact between the blocking wall and the detection means is avoided, so that when the heavy and heavy blocking wall is lowered at high speed, the impact is mitigated by the protrusion. Thus, the impact received by the blocking wall and the lever can be reduced.

  More preferably, a roller is provided near the lower end of the blocking wall and at a position where it contacts or collides with the lever that constitutes the detecting means by the lowering of the blocking wall, the lever that pivotally supports the roller, or the columnar part. 1 is a block diagram of a conveying device including a roller blocking wall; Also in this case, the roller attached to the blocking wall is more preferably a roller covered with a rubber-like substance or a roller formed of a rubber-like substance.

  The protrusion blocking wall and the roller blocking wall are also electrically connected to the lever by contacting or colliding with the lever, the lever supporting the roller, and the columnar part when the blocking wall is raised. It becomes possible to reverse the signal or the mechanical operation, and the return of the relay conveying means can be semi-automated or automated.

  Finally, a combination of various parts such as rollers, pulleys, weights, springs, etc., which does not require a power supply, and as a shut-off mechanism that solves the problems of the present invention, is characterized in that a roller, not a lever, is applied to the detection means. A shut-off mechanism is provided.

  That is, in a transport facility capable of moving a transported object between rooms, a transport device having a start / end position between the rooms, a relay transport unit positioned in a blocking space where a blocking wall between the rooms moves up and down, and a relay transport unit And a detecting means for detecting the blocking operation of the blocking wall, and the relay conveying means is a conveyor that is responsive to the conveying apparatus and is provided near the beginning or end of the conveying apparatus. The detection means is pivotally supported by a first detection roller support member fixed near the start end or the end of the transport device, and is supported by one end of the rotation side plate supported around the rotation axis of the side plate support member. An annular first roller that rotates in contact with the blocking wall, and an annular second roller that is pivotally supported by a second detection roller support member that is fixed near the start or end of the conveying device. It is connected so that it can rotate in reverse and the second rod And the other end of the rotating side plate on which the relay conveying means is pivotally supported at one end, and the other end of the rotating side plate can support the relay conveying means and can retract from the blocking space. It is the interruption | blocking mechanism of the conveying apparatus characterized by being connected with. According to the blocking mechanism, the blocking wall is lowered, the relay transfer device is retracted downward, the blocking wall is raised, and the relay transfer device is returned to the original blocking space. It is a blocking mechanism.

  The mechanical contraction device is preferably a wire with a weight, and more preferably a tension spring in order to realize a stable operation of the blocking mechanism.

  In order to make sure that the first roller makes contact with the descending blocking wall, the first detection roller and the second detection roller are connected by a connecting arm, and the first detection roller, It is preferable that the second detection roller or the connecting arm is connected to expansion / contraction means having one end fixed, and pressure is applied to the first detection roller. The expansion / contraction means is preferably a compression spring or a tension spring with a simple structure depending on the connection method.

  In this way, by adopting a roller that rotates in contact with the descending blocking wall as the detection means, a fireproof and heavy blocking wall that descends at high speed can collide with the detection means. In addition, since only the rollers constituting the detection means rotate, there is no impact received by the blocking wall and the detection means, and the problem of damage to the transport equipment can be solved. In addition, it does not require a power supply, so it is a suitable device in the event of a fire. Further, when the barrier is raised and restored after the fire is extinguished or after a malfunction, the roller constituting the detection means rotates reversely with the rise of the barrier and the relay conveying means can automatically return. .

  As mentioned above, although the interruption | blocking mechanism of the conveying apparatus of this invention was demonstrated, since the interruption | blocking mechanism is used at the time of a fire, all the air piping systems and electrical wiring systems need to be protected with a nonflammable material, and are nonflammable. It is preferably coated with an organic material or a metal material.

  The blocking mechanism of the transfer device according to the present invention includes a transfer device in which a blocking wall such as a fire shutter that descends in the event of a fire is provided in each room, a relay transfer device that transfers a transfer object between transfer devices provided in each room, and the like Without being in direct contact with the transfer equipment, the relay transfer device can be withdrawn from the blocking space where the blocking wall descends. Moreover, since the conventional techniques such as a cylinder, a spring, a roller, and a pulley are used for retracting and returning the relay conveyance device, it is possible to perform a reliable operation against the rising and lowering of the blocking wall. Furthermore, by applying a rubber-like substance lever, roller, piston, etc. to the device that detects the operation of the barrier, the impact caused by the collision between the barrier and the detector can be reduced. Equipment damage can also be avoided.

  Therefore, according to the present invention, fire prevention equipment that has been enhanced by the social background of preventing the expansion of fire damage accompanying the large-scale construction of buildings such as three-dimensional automatic warehouses, distribution centers, etc. where transport equipment is deployed, In the fire prevention equipment that divides the room between buildings and the buildings by the barrier wall such as fire shutter, etc. of the transportation equipment where the transported goods are movably arranged between the rooms in the building and between the buildings, the transportation equipment is damaged. It is possible to provide a transfer device shut-off mechanism that is safe, secure, capable of being dealt with with certainty, and can be quickly restored.

  The operation of this shut-off mechanism is the same as that shown in FIGS. 2A to 2C in the process from the operation of the fire shutter 2-1 to the operation of the air cylinder 5 in both the descending and rising of the fire shutter 2-1; The difference is that the belt conveyor 1-74 rotates largely around the rotation center roller 1-742 of the second relay belt conveyor.

  Here, although the second relay belt conveyor 1-74 composed of four rolls is shown as the relay conveying means, the present invention is not limited to this, and a blocking space where the fire shutter 2-1 descends or The number of rolls is determined according to the roll diameter and the like. Further, the second relay belt conveyor 1-74 does not need to be a belt conveyor, and a general roller conveyor or the like can also be applied.

  In FIG. 5, a telescopic roller telescopic arm 1-753 that telescopically supports the telescopic roller 1-752 of the relay telescopic transport conveyor 1-75 that is a relay transport means is provided in the second chamber that is a transport device. Attached to the side wall 1-522 of the belt conveyor 1-52, and the relay telescopic conveying conveyor 1-75 can be retracted and returned from the shut-off space by the air cylinder 5, and the distal end of the piston 5-1 of the air cylinder 5 and the relay telescopic conveying It is a perspective schematic diagram which shows the interruption | blocking mechanism of the conveying apparatus included by Claim 4 with which the vertical motion roller 1-751 which comprises the conveyor 1-75 was connected by the relay expansion-contraction belt conveyor support part 5-15.

  Regarding the operation of this shut-off mechanism, the process from the operation of the fire shutter 2-1 to the operation of the air cylinder 5 is the same as that of FIGS. When 1 is lowered, the piston 5-1 of the air cylinder 5 is retracted, and when the fire shutter 2-1 is raised, the piston 5-1 of the air cylinder 5 is extended. In this blocking mechanism, the vertically moving roller 1-751 descends as the piston 5-1 contracts, and the telescopic roller 1-752 constituting the relay telescopic conveyor 1-75 moves along the roller telescopic arm 1-753. It is characterized in that it is degenerated and the relay telescopic conveyor 1-75 is retracted from the blocking space. When the fire shutter 2-1 is raised, the opposite operation is performed.

  FIG. 6 shows a roller rotation support member 1-761 that supports the third relay roller 1-76 and is supported by the spherical bearing 1-762 so as to slide on the roller rotation shaft guide plate 1-763. It is a schematic diagram which shows the interruption | blocking mechanism of the conveying apparatus included in Claim 5 connected with piston 5-1 of the air cylinder 5 by the 3rd relay roller rotation support member support shaft.

  In FIG. 6, the detection lever 4-1, the changeover switch 4-2, and the detection device 4 including signal wiring are omitted, but this blocking mechanism operates in the following process. When the fire shutter 2-1 descends along the guide rail 2-2, it collides with the detection lever 4-1, and that the fire shutter shut-off operation has started is signaled as an electrical signal from the changeover switch 4-2. 3 is transmitted to an air switching valve 5-7 (not shown) connected to a high-pressure air tank supply system 5-8 described later. Based on this signal, high-pressure air is supplied from the air pipe 5-2, the piston 5-1 expands, and the roller rotation support member 1-761 supported by the spherical bearing 1-762 becomes the roller rotation shaft guide plate 1-763. Sliding along the top, the third relay roller 1-76 is lifted upward. Further, when the piston 5-1 is extended, the roller rotation support member 1-761 supported by the spherical bearing 1-762 slides on the roller rotation shaft guide plate 1-763 and is provided in the second chamber. The third relay roller 1-76 is retracted from the blocking space by rotating in the direction perpendicular to the transport direction of the transport device 1-5. Conversely, when the fire shutter 2-1 is raised and the switching lever 4-1 is restored, a signal is transmitted to the air switching valve 5-7 through the same route, and high-pressure air is supplied from the air pipe 5-3. The piston 5-1 contracts, and the third relay roller 1-76 returns to the shut-off space in the reverse process of the saving.

  FIG. 7 is a schematic perspective view illustrating a blocking mechanism in the case where there is a step between the transport device 1-42 in the first room and the transport device 1-52 in the second room. A relay inclined plate rotating roller 1-523 pivotally supported by a relay inclined plate rotating roller supporting member 1-524 provided adjacent to 1-52 in the transport device in the second chamber is a relay serving as a relay conveying means. The tip of the piston 5-1 and the relay inclined plate 1-77 are coupled to the inclined plate 1-77 at the most downstream side in the conveying direction so that the relay inclined plate 1-77 can be retracted and returned from the blocking space by the air cylinder 5. 77 shows the blocking mechanism of the transport device included in claim 6 connected by the relay inclined plate support shaft 5-16 of the relay inclined plate 1-77. However, in the case of FIG. 7, the moving direction of the transported object is opposite to that of the previous embodiments, and the transported object moves from the first room 1-1 to the second room 1-2. It is a form.

  The operation of the blocking mechanism is the same as that of the blocking mechanism shown in FIG. 4 and thus will not be described. However, the relay inclined plate 1-77 does not need to be an inclined plate, and is a roller conveyor or belt conveyor. It is possible to apply a general conveyor such as a slat conveyor. When these driveable conveyors are applied instead of the relay inclined plate 1-77, the moving direction of the conveyed product is not limited, and the first chamber 1-1 to the second chamber 1-2. In both directions and vice versa, the transported object can be moved without any problem.

  As described above, the embodiment using the air cylinder as the double-acting means for operating the relay conveying means in the blocking mechanism of the conveying apparatus of the present invention has been described. The air cylinder is a clean device with a simple structure, small size and high safety because the power is compressed air. It can be used even in high-temperature environments and is suitable for double-acting means to be driven in a fire. And because compressed air has elasticity, it is based on the fact that the possibility of damaging the relay transport means is reduced in the withdrawal and return of the relay transport means of the present invention.

  As the air switching valve of the air cylinder, a pneumatic switching valve and an electromagnetic switching valve are generally used, and the shut-off mechanism of the present invention is not particularly limited. From the point of view of not using electricity, a pneumatic switching valve is preferable, and a device with a total pneumatic circuit is possible, but from the viewpoint of switching speed, an electromagnetic switching valve is superior, and can be selected appropriately. Can be used. In particular, in the shut-off mechanism of the present invention, an emergency power source or a self-power generation device can be used, and therefore, it is preferable to select from both in consideration of the switching speed.

  On the other hand, although the high-pressure air of the power source that expresses the characteristics of the air cylinder is supplied by various methods, typical embodiments of an air supply system suitable for the shut-off mechanism of the present invention are shown in FIGS.

  FIG. 8A shows an embodiment of the high-pressure air supply system 5-8 of the air cylinder 5 that drives the shutoff mechanism of the present invention, and supplies air to the air switching valve 5-7 that switches between supply and exhaust of the air cylinder 5. It is a schematic diagram of piping of the high-pressure air supply system 5-8 included in claim 10, wherein the means is a main air tank 5-81 connected to the compressor 5-84 via the switching valve 5-831.

  As is apparent from the figure, the air cylinder 5 has an air switching valve 5-7, throttle valves 5-5, 5 to 5 from a main air tank 5-81 connected to the compressor 5-84 through an on-off valve 5-831. Air pipes 5-2 and 5-3 are connected via -7, and high-pressure air is supplied and exhausted through air supply and exhaust ports 5-21 and 5-31. Here, the flow of high-pressure air when the piston of the air cylinder 5 is degenerated is shown. The air switching valve 5-7 is not particularly limited, and there is no problem with either a pneumatic switching valve or an electromagnetic switching valve.

  Thus, by providing an air tank for storing high-pressure air connected to the compressor via the on-off valve as the high-pressure air supply means, there is no need to increase the size of the device, and the transfer device of the present invention is shut off. It is suitable when it is used only during a fire like a mechanism.

  However, the shut-off mechanism used in an emergency preferably includes an auxiliary air tank via an on-off valve in order to cope with a failure of the main air tank. One embodiment is shown in FIG. 8B. FIG. 8B is an embodiment related to the high pressure air supply system 5-8 of the air cylinder 5 that drives the shut-off mechanism of the present invention. The main air tank 5-81 in FIG. 8A includes an auxiliary air tank 5-82. It is a schematic diagram of piping of the high pressure air supply system included in claim 11.

  Furthermore, it is more preferable to provide an auxiliary tank connected to the compressor via an on-off valve, and one embodiment thereof is shown in FIG. 8C. FIG. 8C shows an embodiment of the high-pressure air supply system 5-8 of the air cylinder 5 that drives the shut-off mechanism of the present invention. The compressor 5-84 is connected to the main air tank 5-81 of FIG. It is a schematic diagram of piping of the high pressure air supply system included in Claim 11 provided with the auxiliary air tank 5-82 connected via 842.

  In the worst case, the air supply means to the air cylinder 5 can be sufficiently operated by an air pipe formed by the air cylinder and the on-off valve. One embodiment of this is shown in FIG. 8D. FIG. 8D shows an embodiment of the high pressure air supply system 5-8 of the air cylinder 5 that drives the shut-off mechanism of the present invention, and supplies air to the air switching valve 5-7 that switches between supply and exhaust of the air cylinder 5. It is a schematic diagram of the piping of the high pressure air supply system included in Claim 12 whose means is air piping 5-2, 5-3. Thus, the air cylinder is particularly excellent from the viewpoint of safety.

  However, the double-acting means of the blocking mechanism of the transport apparatus of the present invention is not limited to an air cylinder, and an electric cylinder is also preferably used. This is because the electric cylinder has different characteristics from the air cylinder. In particular, the electric cylinder has a great feature that it has excellent controllability, the position and speed can be easily adjusted, and the initial movement is fast. Therefore, the high controllability can prevent damage, and the speed of the initial movement is suitable for the evacuation of the relay conveying means requiring urgency. The need for a power supply can be solved by applying an emergency power supply or a self-power generation device, as will be described later.

  FIG. 9 shows an embodiment of the interrupting mechanism of the transport apparatus of the present invention that employs an electric cylinder as the double-action means. FIG. 9 shows a rotating side plate support / cylinder provided on a side wall 1-512 of a belt conveyor 1-51 provided in a second chamber serving as a conveying device, with the first relay roller 1-71 being pivotally supported. The turnable rotation side plate 6 attached to the fixed member 7 is connected to the tip of the piston 10-1 of the electric cylinder 10 by the rotation side plate support shaft 10-11 so that it can be retracted and returned from the shut-off space by the electric cylinder 10. It is the isometric view schematic diagram which shows the interruption | blocking mechanism of the conveying apparatus included by Claim 13 made.

  The electric cylinder 10 includes a motor 10-2 that double-activates the piston 10-1, and is provided with a rotating side plate support and cylinder fixed on a side wall 1-512 of a belt conveyor 1-51 provided in a second chamber. The electric cylinder fixing member 10-5 of the member 7 is fixed and connected to the power source 11 and the signal wiring 4-3 of the detection device 4 via the controller / PLC 10-3, and the electric cylinder 10 is driven according to the instruction of the detection device 4. To do.

  As described above, the double-acting means that controls the retracting and returning of the relay conveying means of the interrupting mechanism of the conveying device of the present invention preferably uses a cylinder, particularly an air cylinder or an electric cylinder. In order to reduce the load and control the operation of the relay conveying means, it is preferable to adopt a mechanism in which a mechanical expansion / contraction device is provided in parallel with the cylinder. One embodiment of such a blocking mechanism is shown in FIGS. 10A and 10B.

  10A is included in claims 14 and 15 in which, in the air cylinder 5 of the shut-off mechanism of FIG. 2A, an air cylinder auxiliary mechanism 9 having a weight 9-1 as a mechanical expansion / contraction device is provided in parallel with the air cylinder 5. It is a perspective schematic diagram which shows the interruption | blocking mechanism of a conveying apparatus. The wire connecting portion 9-21 and the weight 9-1 of the rotating side plate 6 are supported by the wire 9-2 via the wire guide pulley 9-22 and supported by the rotating side plate 6 by the roller rotating shaft 6-2. The first relay roller 1-71 is connected so as to be retractable and returnable from the shut-off space, and prompts the first relay roller 1-71 to quickly retract.

  FIG. 10B is included in claims 14 and 16 in the air cylinder 5 of the shut-off mechanism of FIG. 2A in which an air cylinder auxiliary mechanism 9 having a spring 9-3 as a mechanical expansion and contraction device is provided in parallel with the air cylinder 5. It is a perspective schematic diagram which shows the interruption | blocking mechanism of a conveying apparatus. The spring connecting portion 9-21 of the rotating side plate 6 and the spring connecting portion of the air cylinder fixing member 5-4 are connected by a spring 9-3. As the spring 9-3, a compression spring and a tension spring are used depending on the purpose. In the case of a compression spring, the first relay roller 1-71 pivotally supported on the rotating side plate 6 by the roller rotation shaft 6-2 is stably held, and the first relay roller 1-71 is operated to be retracted. It provides elasticity and compensates for preventing damage to the first relay roller 1-71. In the case of a tension spring, the first relay roller 1-71 is promptly evacuated.

  As described above, in a transport facility capable of moving a transported object between rooms, a transport device having a start / end position between the rooms, a relay transport unit positioned in a blocking space where the blocking wall between the rooms moves up and down, and a blocking wall Regarding the blocking mechanism of the transport apparatus of the present invention, comprising a detecting means for detecting the blocking operation and a double-acting means capable of stopping and driving the relay transport means, the detecting means includes a lever that contacts or collides with the blocking wall; Using a detecting device composed of a switching device that converts the displacement of the lever into a signal and a wiring that transmits the signal to the double-acting means, and using a cylinder as the double-acting means, the retracting operation and the return operation of the relay conveying means Embodiments included in claims 1 to 17 characterized by the above have been described. Next, an embodiment of the shut-off mechanism of the present invention characterized by the detection means will be described.

  FIG. 11 shows the transfer device of the present invention included in claim 18, characterized in that a power generation shutter contact roller 11-1 is used instead of the detection device 4 as detection means of the blocking mechanism of FIG. 2A. It is a general | schematic schematic diagram which shows the interruption | blocking mechanism. As is apparent from the figure, the detection means includes a power generation shutter contact roller 11-1 and an amplifier-equipped generator 11-2 fixed to a power generation device support member 11-4, and both are connected by a generator drive wire 11-2. Is a self-power generating device that is directly coupled so as to be rotatable in conjunction with each other. When the power generation shutter contact roller 11-1 is brought into contact with the fire protection shutter 2-1 where the power generation shutter contact roller 11-1 descends and rotates, and is transmitted through the wiring 11-5 to the electromagnetic switching valve 5-71 connected to the air cylinder 5. The piston 5-1 of the air cylinder 5 is retracted, and the first relay roller 1-71 pivotally supported on the rotating side plate 6 is retracted. Conversely, when the fire shutter 2-1 is raised, the piston 5-1 is extended and the first relay roller 1-71 is restored.

  This detection device capable of self-power generation can also operate an electric cylinder by connecting to the electric cylinder.

  In the case of using double-acting means that operates with a power source, for example, the detection means is connected not only to the detection device 4 and the power generation contact roller 11-1, but also to a fire alarm and / or a sprinkler (not shown). . Similarly, although not shown in the figure, when a double-acting means that requires a power source is used in the interrupting mechanism of the transfer device of the present invention, a power failure is expected in the event of a fire, so it can be switched to an emergency power source. is there.

  Next, in a transport facility capable of moving a transported object between rooms, a transport device having a start / end position between the rooms, a relay transport unit positioned in a blocking space where the blocking wall between the rooms moves up and down, and a blocking wall As a shut-off mechanism of the transport device of the present invention, comprising a detecting means for detecting the shut-off operation of the present invention and a double-acting means capable of stopping and driving the relay transport means, an air that combines the detecting means and the double-acting means. An embodiment in which double-acting means capable of moving in a state in which an applied pressure is applied during reciprocating movement without using a power source such as electricity or electricity is illustrated.

  FIG. 12A is an embodiment of a shut-off mechanism to which double-acting means that does not use a power source such as air or electricity is applied. The second chamber is a transport device that supports the second relay roller 1-73 and supports it. The second relay roller support member 1-731 slidable on the second relay roller slide rail 1-733 attached to the roller conveyor 1-51 provided in the tension conveyors 12-31, 12- 22 is a schematic side view showing a blocking mechanism of a transport device included in claim 21, which is connected to the blocking space so as to be retractable and returnable by a second relay roller tension spring drive device 12-3-1 using 32. FIG. .

  The meaning of “combining the detection means and the double-action means” means a detection composed of a fire shutter detection lever 12-1, a wire winding device 12-2, a wire 12-21, and a wire guide pulley 12-22. And double tension means comprising a first tension spring 12-31, a second tension spring 12-32, a second tension spring stopper 12-33, and a second tension spring stopper holding member 12-34. This is based on a blocking mechanism that interlocks with the second relay roller tension spring drive device 12-3-1 to retract the second relay roller. That is, in this blocking mechanism, when the fire shutter 2-1 is lowered, the fire shutter detection lever 12-1 is rotated downward, and the wire take-up device 12-2 pulls the wire 12-21 and the second pull. The second tension spring stopper 12-33 held by the spring stopper holding member 12-34 is released upward, and the second relay roller 1 is joined by the first tension spring 12-31 and the second tension spring 12-32. -73 performs an operation of evacuating from the blocking space. When the fire shutter 2-1 is lifted, the fire shutter detection lever 12-1 is returned to lower the second tension spring stopper 12-33, and the second relay roller 1-73 is returned although it is semi-automatic. Can do. The first tension spring 12-31 does not necessarily have to be a spring, but relaxes the operation of the second relay roller 1-73, and is connected to the roller conveyor 1-51 provided in the second chamber. A compression spring is preferred to prevent damage due to collision.

  FIG. 12B is also an embodiment of the present invention, in which the second relay roller 1-73 is pivotally supported, and the second relay roller 1-51 attached to the roller conveyor 1-51 provided in the second chamber, which is a transport device. The second relay roller support member 1-731 that can slide on the relay roller slide rail 1-733 is moved from the blocking space by the second relay roller weight driving device 12-3-2 using the weight 12-35. It is a side surface schematic diagram which shows the interruption | blocking mechanism of the conveying apparatus included in Claim 22 connected so that retraction | saving and return were possible.

  In this case, the detection means operates with the same mechanism as in FIG. 12A, but the second relay roller weight driving device 12-3-2 that retracts the second relay roller 1-73 is connected to the first tension spring 12-. 31, a weight 12-35, a weight stopper 12-36, and a weight stopper holding member 12-37. When the wire 12-21 is pulled, the weight stopper 12-36 is released and the weight 12-35 falls. By doing so, the second relay roller 1-73 is retracted. The return of the second relay roller 1-73 and the first tension spring 12-31 are the same as in FIG. 12A.

  Furthermore, the present invention combines various parts with the problem of realizing a shut-off mechanism that is safe and secure, can be dealt with reliably, and can be recovered quickly without damage to the transport equipment due to the drop of the shut-off wall. It is also realized by a shut-off mechanism that does not require a power source. One embodiment thereof is shown in FIGS. 13A, 13B, and 14. FIG.

  In FIG. 13A, the first relay roller 1-71 is pivotally supported by a roller rotation shaft 6-2 and is attached to a side wall 1-512 of a roller conveyor 1-51 provided in a second chamber as a transport device. The rotation side plate suspension pin 12-42 of the rotation side plate 6 that can be rotated by the rotation side plate rotation shaft 6-1 is integrated with the fire prevention shutter detection lever 12-1 and the rotation side plate suspension lever 12-41. 24. The conveying device included in claim 23, wherein the first relay roller releasing arm 12-4 is suspended so that the first relay roller 1-71 is retracted from the blocking space as the fire shutter is lowered. It is a perspective schematic diagram which shows the interruption | blocking mechanism. Moreover, it is a perspective schematic diagram which also shows the interruption | blocking mechanism of the conveying apparatus included by the bearing 12-42 provided in the rotation side board suspension pin 12-42.

  The operation of this blocking mechanism is very simple, and the first relay roller releasing arm 12-4 in which the fire shutter detecting lever 12-1 and the rotating side plate suspension lever 12-41 are integrated is pivotally supported. Using the first relay roller release arm rotating shaft 12-44 fixed to the relay roller release arm support member 12-43 as a fulcrum, the first relay roller 1-71 is pivotally supported by the roller rotation shaft 6-2, Since the rotating side plate 6 attached to the side wall 1-512 of the roller conveyor 1-51 provided in the second chamber that can be rotated by the rotating side plate rotating shaft 6-1 is suspended, a fire-proof shutter When 2-1 descends and collides with the fire shutter detection lever 12-1, the rotating side plate suspension lever 12-41 rotates about the first relay roller release arm rotating shaft 12-44 as a rotating shaft. Easily from side plate suspension pins 12-42 Is, first relay rollers 1-71 is retracted from breaking space. The fitting of the bearing 12-45 to the rotation side plate suspension pin 12-42 means that the rotation side plate suspension lever 12-41 uses the relay roller release arm rotation shaft 12-44 as a rotation axis to suspend the rotation side plate suspension. This brings about an effect of further easily detaching from the holding pins 12-42. The work of raising the fire shutter 2-1 to restore the shut-off mechanism is not automatically performed. However, because of the simple structure, the rotation side plate suspension pin 12-42 and the rotation side plate suspension lever 12- 41 can be easily suspended and restored.

  13B shows that the fire prevention shutter detection lever 12-1 and the first relay roller release arm support member 12-43 of FIG. 13A are suspended by the rotation side plate suspension lever stabilization spring 12-46. It is the isometric view schematic diagram which shows the interruption | blocking mechanism of the conveying apparatus included in Claim 25 which was assisted. This rotating side plate suspension lever stabilization spring 12-46 uses a tension spring, enables stable delivery of the first relay roller 1-71 and facilitates the work of restoring the blocking mechanism. There is an effect to make.

  In FIG. 14, the fourth relay roller retracting arm 12-5 in which the fire shutter detection lever 12-1 and the fourth relay roller 1-78 are integrated is a column 12-51 of the fourth relay roller retracting arm. The fourth relay roller 1-78 is pivotally supported by a fourth relay roller retracting arm support shaft 12-52 fixed to the shaft, and the fourth relay roller 1-78 is retracted from the blocking space by the lowering of the fire shutter 12-1. FIG. 27 is a schematic side view illustrating a blocking mechanism of the transport device included in claim 26, which is pressed to hold the fourth relay roller 1-78 by the fourth relay roller retracting arm holding spring 12-53. .

  In this blocking mechanism, the fourth relay roller retracting arm holding spring 12-53, which is a compression spring, is fixed by the fourth relay roller retracting arm holding spring fixing member 12-532, and the fourth relay roller retracting arm is fixed. Since the fourth relay roller retracting arm 12-5 is pressed by the retracting arm connecting portion 12-531, the fourth relay roller 1-78 is connected to the roller conveyor 1-41 provided in the first chamber. The delivery of the transported object is stably performed with the roller conveyor 1-51 provided in the second room, but when the fire shutter 2-1 is lowered, the fire shutter of the fourth relay roller retracting arm 12-5 is fired. The fourth relay roller retracting arm 12-5 collides with the detection lever 12-1, and the fourth relay roller retracting arm holding spring 12-53 is retracted, and the fourth relay roller retracting arm support is supported. The fourth relay roller 1-78 is retracted from the blocking space by rotating about the shaft 12-52 (the fourth relay roller 1-78 is retracted to the broken fourth relay roller 1-78 ′. .) Since the fire shutter 2-1 is raised and the fire shutter detection lever 12-1 is returned to its original position, the shut-off mechanism is restored by the action of the fourth relay roller retracting arm holding spring 12-53. The relay roller retracting arm 12-5 is restored, and the fourth relay roller 1-78 is automatically restored to the original position.

  As described above, the embodiments of various types of blocking mechanisms that solve the problems of the present invention have been described. However, these are merely examples, and the present invention is not limited thereto, and does not depart from the scope of the claims. Various modifications can be made within the range. Furthermore, the present invention describes various embodiments of the material and configuration of the lever used for the detection means as various problem solving means common to the above-described blocking mechanism. These are mainly intended to alleviate the impact and damage to the barrier wall and the barrier mechanism, and to facilitate the restoration of the transport facility when the barrier wall is opened. Here, the detection device 4 composed of the detection lever 4-1, the changeover switch 4-2, and the signal wiring 4-3 will be described with reference to a representative example, but another embodiment of the present invention will be described. The present invention can also be applied to the detection lever 12-1.

  FIG. 15A shows that the detection lever 4-1 is an elastic substance detection lever when the detection means of the present invention is a detection device 4 having a detection lever 4-1, a changeover switch 4-2, and a signal wiring 4-3. 4-11 is a schematic diagram showing a detection device provided with an elastic material detection lever 4-11 pivotally supported by a changeover switch 4-2. This elastic substance detection lever 4-11 switches the displacement caused by direct contact with or colliding with a heavy barrier wall that descends at high speed, such as a fire shutter, to an electrical signal and starts the retracting operation of the relay conveying means. It must be a structure having at least elasticity. The same applies to the case where the displacement caused by contacting or colliding with a heavy barrier wall that descends at a high speed, such as the detection lever 12-1, is switched to a mechanical operation. Accordingly, in the following embodiment, the detection device 4 including the detection lever 4-1, the changeover switch 4-2, and the signal wiring 4-3 will be described as a representative example. Since it is applicable to the detection lever 12-1 of another embodiment, the description is omitted. It shall be described only when there is a special significance or effect.

  However, contact or collision with a heavy barrier wall that descends at high speed has an impact beyond imagination and can lead to damage or destruction of the detection device and barrier as well as the detection lever that contacts or collides . Therefore, it is preferable that the detection lever that is in direct contact with or collides with the blocking wall is covered with a rubber-like substance that reduces the impact.

  15B, the elastic substance detection lever 4-1 of FIG. 15A includes a rubber-like substance covering detection lever 4-12 in which the elastic substance 4-121 is coated with a rubber-like substance, and the rubber-like substance covering detection lever 4-12. Is a schematic diagram showing a detection device 4 that is pivotally supported by a changeover switch 4-2. The rubber-like substance 4-121 covering the elastic substance 4-121 is not particularly limited as long as it is an organic polymer material having a low elastic modulus, but is preferably natural rubber or synthetic rubber, and in particular, butadiene rubber. Chloroprene rubber, nitrile rubber and various thermoplastic elastomers are suitable. If repeated use is not considered, thermoplastic polymer materials can also be applied. The elastic material 4-121 in this case may be the same elastic body as the elastic material detection lever 4-11 in FIG. 15A, but it is suitable for covering with a rubber-like material, for example, a rubber-like material. It is preferable that the elastic structure has good adhesion.

  15C, for the same purpose, the detection lever 4-1 of FIG. 15A includes a rubber balloon covering detection lever 4-13 in which an elastic material 4-131 is covered with a rubber balloon 4-132, and the rubber balloon covering detection lever. 4-13 is a schematic diagram showing the detection device 4 that is pivotally supported by a change-over switch 4-2 so as to be pivotable. In this case, the elastic material 4-131 may be the same elastic body as the elastic material detection lever 4-11 shown in FIG. 15A, but is preferably an elastic structure suitable for covering a rubber balloon.

  In FIG. 15D, for the same purpose, the detection lever 4-1 in FIG. 15A includes a rubber-like substance detection lever 4-14 formed of only a rubber-like substance, and the rubber-like substance detection lever 4-14 is a changeover switch. It is a schematic diagram which shows the detection apparatus pivotally supported by 4-2. In this case, since it does not have an elastic structure, it is the same material system as the rubber-like substance used for covering the elastic structure, but preferably has a higher elasticity.

  For the same purpose, FIG. 15E shows a rubber in which the detection lever 4-1 shown in FIG. 15A has a roller wheel 4-151 covered with a rubber roller tire 4-152 attached to the tip of an elastic arm 4-153. It is a schematic diagram showing a detection device provided with a detection lever 4-15 with a rubber-like substance covering roller, and the detection lever 4-15 with a rubber-like substance covering roller pivotally supported by a changeover switch 4-2. This detection lever has the most excellent impact mitigation effect because the roller rotates. In addition, although the rubber-like roller tire 4-152 is used here, it does not necessarily need to be a tire of a rubber-like substance, and if it is an organic polymer material, it will not specifically limit. Further, the roller wheel 4-151 is not necessarily required, and it is more preferable that the entire roller is a rubber-like tire.

  In FIG. 16A, the detection lever 4-1 in FIG. 15A is a spring-type elasticity detection lever 4-16, and the spring-type elasticity detection lever 4-16 is pivotally supported by a changeover switch 4-2. It is an outline schematic diagram showing a detection device. As is apparent from the figure, the spring-type stretchable detection lever 4-16 has a compression spring 4-163 inserted into a cylindrical member 4-161, a columnar member 4-162 fitted therein, and the compression spring 4 The piston is directly connected to -163 and degenerates by contact or collision with the blocking wall. Although the figure shows that the columnar member 4-162 is formed of a rubber-like substance, it may be a columnar part covered with a rubber-like substance or a columnar part of which only the tip is formed of a rubber-like substance. .

  In FIG. 16B, the detection lever 4-1 in FIG. 15A is an air piston type stretchable detection lever 4-17, and the air piston type stretchable detection lever 4-17 is pivotable by a changeover switch 4-2. It is a general | schematic schematic diagram which shows the supported detection apparatus. The air piston type stretchable detection lever 4-17 is an air cylinder in which air 4-173 is sealed and fitted in a cylinder 4-171 with a piston 4-172, and is brought into contact with or colliding with a blocking wall. Degenerate. In this case, the piston 4-172 needs to seal the air 4-173, and the rubber-like substance 4-174 is fixed, covered, or integrally molded to the tip of the main body made of a material that slides with the cylinder 4-171. You need to use something.

  In addition to avoiding damage or destruction of the detection device and the barrier wall due to contact or collision with the heavy barrier wall that descends at high speed, the purpose of employing such a detection lever is as follows. First, the frictional force in contact with a blocking wall such as a fire shutter is increased, and the detection lever can be reliably operated. Moreover, it becomes easy to reversely switch the electrical signal or mechanical operation of the detection lever due to the rising of the barrier after the fire is extinguished or after the malfunction of the barrier, and the return of the relay conveying means can be semi-automated or automated.

  FIG. 17A is a schematic diagram showing a situation in which the rubber-like substance covering detection lever 4-12 in FIG. 15B comes into contact with the fire shutter 2-1 to operate the changeover switch 4-2. Since the rubber-like substance 4-122 is coated, as the fire shutter 2-1 is lowered, it is surely rotated and displaced downward by the frictional force, and passes through the signal wiring 4-3 from the changeover switch 4-2. Thus, a signal is transmitted to the cylinder so that the relay conveyance means can be retracted from the blocking space. On the other hand, when the fire shutter 2-1 is raised to restore the shut-off device, the rubber-like substance covering detection lever 4-12 is surely restored, and the changeover switch 4-2 passes through the signal wiring 4-3. A signal is transmitted to the cylinder to return the relay conveying means to the original position. As is apparent from this figure, since the rubber-like substance 4-122 is coated, damage to the rubber-like substance covering detection lever 4-12, the detection device 4, and the barrier wall due to the collision with the barrier wall is prevented. can do.

  FIG. 17B is a schematic diagram illustrating a situation where the detection lever 4-15 with a rubber-like material covering roller in FIG. 16E comes into contact with the fire shutter 2-1 to operate the changeover switch 4-2. In this case, since the rollers 4-151 and 4-152 rotate, the effect of the present invention is more than that of the rubber-like substance coating detection lever 4-12 shown in FIG. 17B. In particular, the rotation of the rollers 4-151 and 4-152 during recovery makes it possible to operate the detection device 4 more reliably.

  FIG. 17C is a schematic diagram showing a situation where the air piston type stretchable detection lever 4-17 in FIG. 17B comes into contact with the fire shutter 2-1 to operate the changeover switch 4-2. The detection lever 4 can operate the detection device 4 more reliably because the piston 4-171 presses the fire shutter 2-1 using the air 4-173 as a power source.

  Furthermore, in addition to the material and configuration of such a lever, a protrusion or roller is provided near the lower end of the blocking wall, at a position where it contacts or collides with various detection levers that constitute the detecting means by lowering the blocking wall. By using a protrusion blocking wall or a roller blocking wall as a blocking mechanism of the conveying device including the blocking mechanism, direct contact between the blocking wall and the detection means is avoided, so that the blocking wall has fire resistance and weight. However, when descending at a high speed, the impact is reduced by the protrusion or the roller, and the impact received by the detection means and the blocking wall can be reduced. Also in this case, when the blocking wall rises, the projections and rollers come into contact with or collide with the various detection levers, so that the electrical signals or mechanical operations of the various detection levers can be switched in reverse, and relay conveyance is performed. The return of the means can be semi-automated or automated.

  FIG. 18A and FIG. 18B show examples of these embodiments, but it is possible to use a blocking mechanism of a combination of various detection levers and fire shutters. FIG. 18A shows a combination of a rubbery material coating detection lever 4-12 and a fire shutter 2-1 provided with a detection lever pressing projection 2-12. FIG. 18B shows a rubbery material coating detection lever 4-12 and detection. It is a schematic diagram which shows the condition which operates the detection apparatus 4 by the combination with the fire shutter 2-1 which provided the lever press roller 2-11. In the figure, an example in which the detection lever pressing projection 2-12 is firmly fixed to the fire shutter with a rubber-like substance is shown. The detection lever pressing roller 2-11 is a roller wheel that is pivotally supported by an elastic arm 2-113. Although a roller in which 2-111 is covered with rubber-like roller tire 2-112 shows an example in which an elastic arm 2-113 and a fire-proof shutter are fixed by welding or the like, it is not limited thereto.

  In particular, the fire shutter 2-1 provided with the detection lever pressing roller 2-11 is an effective solution for achieving the object of the present invention. It shows in FIG.

  FIG. 19 shows a shut-off mechanism including a fire-proof shutter 2-1 provided with a detection lever pressing roller 2-11 in the shut-off mechanism of the transport apparatus shown in FIG. A fixed roller wheel (not shown) 2-111 is covered with a rubber roller tire 2-112 and the fire shutter detection lever 12-1 comes into contact with the fourth relay roller retracting arm 12-5. It is a side surface schematic diagram which shows the condition which act | operates. As is apparent from the figure, the detection lever pressing roller 2-11 provided on the fire shutter surely rotates and displaces the fire shutter detection lever 12-1 when the fire shutter is lowered, and the fourth relay. The fourth relay roller retracting arm 12-5 rotates downward with the roller retracting arm support shaft as a fulcrum, and the fourth relay roller 1-78 can retract from the blocking space (fourth relay roller 1). -78 is retracted to the broken fourth relay roller 1-78 '). On the other hand, when the fire shutter 2-1 is raised, the detection lever pressing roller 2-11 is reliably displaced by turning the fire shutter detection lever 12-1 upward when the fire shutter is lowered, and the fourth relay roller is retracted. The fourth relay roller retracting arm 12-5 rotates upward with the arm support shaft as a fulcrum, and the fourth relay roller 1-78 can return to the original position.

  Finally, a combination of various parts such as rollers, pulleys, weights, springs, etc., which does not require a power supply, and as a shut-off mechanism that solves the problems of the present invention, is characterized in that a roller, not a lever, is applied to the detection means. An embodiment of the blocking mechanism is shown in FIGS.

  FIG. 20A shows a second detection roller 13-2 for driving a first relay roller connected to rotate reversely with the first detection roller 13-1 in contact with the fire shutter 2-1; The relay roller 1-71 is pivotally supported by the roller rotation shaft 6-2, and the rotation side plate rotation shaft 6-1 attached to the roller conveyor 1-51 provided in the second chamber as a transport device is the center. The first relay roller 1-71 is retracted from the blocking space by the rotation of the first detection roller 13-1 that contacts the fire shutter when the fire shutter 2-1 is lowered. And the rotation side plate 6 and the rotation side plate holding weight 13-23 are connected so as to hold the first relay roller 1-71. It is a side surface schematic diagram which shows the interruption | blocking mechanism of an apparatus.

  Here, the first detection roller 13-1 that contacts the fire shutter is preferably an annular pulley that covers a circumference that contacts the fire shutter 2-1 with a rubber-like substance.

  This blocking mechanism operates to retract and return the first relay roller as follows. When the fire shutter 2-1 is lowered, the first detection roller 13-1 that is in contact with the fire shutter fixed to the first detection roller support member 13-11 is rotated, and a wire or the like is rotated so as to be rotated in reverse thereto. The second detection roller 13-2 that drives the first relay roller fixed to the second detection roller support member 13-21 connected in (1) also rotates. Then, the first relay roller 1-71 is pivotally supported by the roller rotation shaft 6-2, and the rotation side plate rotation shaft attached to the roller conveyor 1-51 provided in the second chamber which is a conveying device. Rotation side plate drive wire 13-22 attached to the rotation side plate support shaft 13-25 of the rotation side plate 6 that rotates about 6-1 is a second detection roller 13 that drives the first relay roller. The rotation side plate support shaft 13-25 side of the rotation side plate 6 is lifted with the rotation side plate rotation shaft 6-1 as a fulcrum, and the rotation side plate holding weight 13-23 is lifted. The first relay roller 1-71 is pivoted downward to be retracted (the first relay roller 1-71 is retracted to the broken first relay roller 1-71 ′, and so on). . Conversely, when the fire shutter 2-1 is raised, the two detection rollers 13-1 and 13-2 are rotated in reverse, so that the rotating side plate holding weight 13-23 is lowered and the roller supporting shaft 6 of the rotating side plate 6 is lowered. The -2 side is lifted with the rotation side plate rotation shaft 6-1 as a fulcrum, and the first relay roller returns to the original position.

  This shut-off mechanism requires fire prevention equipment that divides between rooms and buildings using a shut-off wall such as a fire-proof shutter, which is the subject of the present invention, using only the lowering motion of the shut-off wall without using a power source. The relay transfer device installed between the transfer devices in different rooms, which delivers and transfers the object to be transported, is surely and quickly withdrawn without being damaged with respect to the closing of the barrier wall. Provides a shut-off mechanism for a transport device that can be quickly restored.

In addition, the detection roller connecting arm 13-3 connects the first detection roller 13-1 that contacts the fire shutter and the second detection roller 13-2 that drives the first relay roller, and the second chamber. The first detection roller 13 that is in contact with the fire shutter is connected to the side wall 1-512 of the roller conveyor 1-51 and the second detection roller 13-2 that drives the first relay roller by a compression spring.
