  First, the background of the present invention will be described. In buildings, etc., when constructed beyond a predetermined floor area, in order to respond to disasters such as fires and earthquakes, for example, the Fire Service Law refers to the Building Standard Act and refers to fire protection such as fire protection shutters Equipment is to be provided. The buildings also include storage warehouses for articles, etc., and buildings such as manufacturing facilities and transport facilities.

Specifically, the fire rating in buildings, for example, floor space ≧ 1,500 m ^2, etc., (Article 112 Building Standard Law Enforcement Order) installed are obliged such fire protection by a predetermined area compartment fire It is also cited in the law.

  For example, FIG. 9 is a view for explaining the relationship between a transport device as a background art and a blocking facility (hereinafter also referred to as a blocking wall or a blocking facility) for blocking a predetermined section such as a fire protection facility, as shown in FIG. In addition to the columns 92, 93, etc. of the building, fire protection equipment 94 including equipment for guiding a blocking wall (fire protection shutter etc.) is provided in a wide area building of a size larger than the specified area. The wall itself is not shown). When the transfer device 91 is disposed across the fire protection facility 94, when the blocking wall descends along the guide of the fire protection facility 94 at the occurrence of a disaster such as a fire, the corresponding part of the transfer path under the blocking wall or the blocking wall It will break itself. Further, in the case where the lower surface of the blocking wall has a function of detecting an obstacle, there is also a problem that the detection is stopped by detecting the transfer device and the fire prevention function is not performed.

  Therefore, it is also considered to separate the conveyance path of the conveyance device 91 into two and provide a movable conveyance path between them so as not to prevent the lowering of the blocking wall of the fire protection equipment 94.

  In addition, in the case where there is a level difference in the conveyance path of the divided conveyance device, it is also considered to provide an inclined plate between the conveyance paths.

  The present invention relates to a sloped transport path provided to connect the stepped transport paths of transport devices having different heights, and a combination of two elastic sheet materials is used in this transport path. It is an object of the present invention to provide a shutoff mechanism which normally functions as a sloped conveyance path and which facilitates evacuation when it is necessary to shut off based on new ideas. Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view for explaining a blocking mechanism of a transport path according to an embodiment of the present invention.

  As shown in FIG. 1, as a blocking operation, for example, at a place where equipment 2 for lowering and blocking a predetermined section is disposed, the transport apparatus 1 has a first transport apparatus 11 having different heights. And the second transport device 12 and arranged to avoid this blocking gap. A belt conveyor is shown as an example of the transport paths 111 and 121 in both the first transport device 11 and the second transport device 12. These belt conveyors are shown by way of example and are not limited to the belt conveyor type, and may be of a roller conveyor configuration or by other conveying means. Hereinafter, it is simply referred to as a conveyor, or a conveyor is used synonymously with a transport path. A guide rail 21 is provided in the blocking facility 2 for guiding when the blocking wall (not shown) descends. A transport path connecting between the transport path (conveyor) 111 of the transport device 11 and the transport path (conveyor) 121 of the transport device 12 disposed in a predetermined gap (indicated by arrow A) including the lowering portion of the blocking wall. 13 are provided. Upper upper side portions of the conveyance path 13 are rotatably attached to a shaft 131 at an end of the conveyance device 11. The transport path 13 is inclined so as to absorb a step between the transport path (conveyor) 111 and the transport path (conveyor) 121. That is, the transport path 13 functions as an inclined plate.

  One feature of the present invention is that the transport path (inclined plate) 13 is constituted by a plate-like body having different materials. The plate-like body may be a plate-like plate having a flat surface, and the elasticity of the portion disposed on the upper side is different from the elasticity of the portion disposed on the lower side, the elasticity of the portion disposed on the lower side is increased, and the retraction operation is performed. And affinity with the downstream conveyance path (conveyor).

  The plate-like body (conveying path 13) may be constituted by one member (one plate-like thing), but in the illustrated example, it will be described below with a two-sheet structure. The plate-like member (conveying path 13) is constituted by a plate 13a made of a material having a first elasticity and a plate 13b made of a material having a second elasticity having a greater elasticity than the elasticity of the first plate 13a. Is shown. In addition, a board | plate material should just be a plate-shaped shaped thing, and the material is not limited to a wood or steel materials. Further, as a plate material having elasticity, it may be elastic, easy to deform and recoverable, and it may be flexible or flexible (the same applies to the following).

  Usually, the transport device 11 and the transport device 12 are used as a device for transporting articles and the like by the transport path 13 connecting the two. For example, it is used in a physical distribution system or the like, and in the illustrated example, articles and the like are sent from the left side to the right side to the transport path (conveyor) 111, the transport path (inclined plate) 13 and the transport path (conveyor) 121. For articles and the like, it is not limited to various goods, and is also used for the conveyance of conveying materials (including scraps, broken materials, waste materials, unnecessary materials, and recycled materials) such as cardboard that has become unnecessary after opening.

  When a blocking operation such as a fire occurrence or the like causes the descent of the blocking wall to occur, the transport path (inclined plate) 13 rotates downward about the rotation shaft 131 and moves out of the range of the blocking operation. The rotational movement of the inclined plate 13 is due to the fact that the blocking wall is lowered and the lower end of the blocking wall presses the plate 13 a of the inclined plate 13. The inclined plate 13 has a combined structure of a first elastic plate member 13a and a plate member 13b having a larger elasticity than the first plate member 13a. Under normal conditions, the lower end of the plate 13b is disposed on the transport path 12, and articles etc. slide on the conveyor from the inclined surface. Further, the upper end of the plate member 13a may be in an engagement relationship to be held by the rotation shaft 131 with a predetermined holding force. That is, it is sufficient if the holding force of the plate member 13a can be made to be able to rotate with a pressing force less than the pressing force at which the lower end of the blocking wall is detected as an obstacle. That is, even when there is a pressure switch or the like that detects an obstacle at the lower end of the blocking wall, it is sufficient to be able to perform rotational operation with a pressing force at which it does not operate. Even if it can, it can be considered possible.

  In addition, when the transport path (slanted plate) 13 is rotationally moved, the plate 13b has greater elasticity, so that the tip end side contacts the transport path (conveyor) 121 and moves downward against the transport path 121. However, no damage such as damage will occur.

  The elastic plate material 13b may be made of a plastic, a hard vinyl, a plate-like rubber material, or the like, or a flame-retardant material, a non-combustible material, or the like that can withstand abrasion or breakage.

  By using the elastic plate 13b, it is possible to prevent falling off or pinching when moving an article etc. to the downstream conveyance path (conveyor) 121, and it is possible to prevent the falling off and pinching, especially including cardboards. It is suitable for transporting unnecessary materials or recycled materials etc.).

  FIGS. 2A and 2B are side views for explaining the shutoff mechanism of the conveyance path device according to the embodiment of the present invention shown in FIG. 1, and FIG. 2A shows a normal use state and a state before lowering of the shutoff wall. The figure to be described, FIG. 2B is a view for explaining a state in which the transport path is retracted with the lowering of the blocking wall. In both FIG. 2A and FIG. 2B, the same reference numerals as in FIG. 1 denote the same objects (the same applies hereinafter).

  In FIG. 2A, in the normal use state and in the state before lowering of the blocking wall, the upper part of the conveying path (conveyor) 111, the plate 13a forming the conveying path (sloped plate) 13, the plate 13b, and the conveying path (conveyor) 121 Articles are transported from the left side to the right side. The plate members 13a and the plate members 13b forming the transport path (inclined plate) 13 are fixed to each other by adhesion, screws or the like in a state of being mutually offset, and arranged and formed so as to bridge between the transport path (conveyor) 111 and the transport path (conveyor) 121 doing. Both upper sides of the plate 13 a are rotatably attached to the rotating shaft 131. The plate member 13 b is disposed in such a manner that the lower side thereof is placed on the conveyance path (conveyor) 121.

  In this state, when the blocking operation starts and the blocking wall (not shown) is lowered from above by the guide rail 21, the lower end of the blocking wall is pressed from the upper surface of the plate 13a of the inclined plate 13 and the inclined plate Road) 13 will push the whole downward. The inclined plate (conveying path) 13 rotates downward about the upper rotation axis, and is in the state shown in FIG. 2B. At this time, due to the elasticity of the plate 13 b of the inclined plate 13, the end of the conveyance path 121 is bent and deviated, and becomes as illustrated in FIG. 2B. During this time, even if the conveyed product such as an article is passing through the inclined plate, it does not become an obstacle because it slides to the conveyance path 121 by the inclination angle and moves to the conveyance path 121.

  In addition, when the transport material becomes an obstacle, the flow is stopped by stopping the operation of the upper (upper) transport path (conveyor) by the notification of the occurrence of a fire or the like, and the flow is stopped by reverse rotation operation. The conveyor can be coped with by operating for a predetermined time by an emergency power source or the like.

  As described above, since the transport path shutoff mechanism shown in FIGS. 1, 2A and 2B is physically and mechanically movable, it can be effectively retracted even in the event of a power failure due to the occurrence of a fire or the like.

  Further, as shown in FIG. 3A, in the apparatus provided with the transport path 13 having a slope between the first transport path 111 and the second transport path 121, the blocking wall is detected in advance by detecting the blocking operation. The transport path 13 may be retracted without the aid of

  FIG. 3A is a perspective view for explaining a blocking mechanism of a transport path according to a second embodiment of the present invention. The present invention is characterized by, for example, a blocking mechanism which retracts the lower transfer path by detecting the lowering of the blocking wall in advance.

  In FIG. 3A, the same reference numerals as in FIGS. 1, 2A and 2B indicate the same objects, and the blocking wall serves as a blocking operation, for example, at a place where the facility 2 for blocking the inside of a predetermined section is disposed. The conveying device 1 includes a first conveying device 11 and a second conveying device 12 which have different heights, and a gap is provided between the conveying devices. The conveyance path 13 in which the gap is inclined is disposed. The blocking facility 2 is provided with a guide rail 21 for guiding when the blocking wall descends. According to the present invention, the blocking wall falling along the guide rail 21 is detected in advance, and the transport path (inclined plate) 13 in the gap between the transport devices is retracted. A detection mechanism 4 for detecting the blocking wall, an air changeover switch 42, and air pipes 43 and 44 for air supply and discharge are attached. A detection pin 41 is attached to the detection mechanism 4 so as to cross the guide rail of the blocking wall. When the detection pin 41 rotates downward with the lowering of the blocking wall, the air changeover switch 42 is operated to retract the transport path 13.

  As described in the previous embodiment, the transport path (inclined plate) 13 includes the plate 13 a and the plate 13 b, and is adhered and fixed in a mutually shifted state. Both upper sides of the plate 13 a are rotatably attached to the rotating shaft 131. The lower side of the plate member 13 b is placed on the conveyance path 121. The plate 13a is made of a relatively small elastic material, and the plate 13b is made of an elastic material larger than the elasticity of the plate 13a.

  Further, on both sides of the plate member 13a, piston rods 31 extending from the air cylinder 3 are attached at predetermined positions 311 thereof to support the entire transport path (inclined plate) 13 and to be able to be retracted if necessary. At the time of retraction, the transport path (inclined plate) 13 is rotated as indicated by an arrow a about the rotation shaft 131 as an axis.

  One end of the air cylinder 3 is swingably attached to the fixed portion 34 to the side plate of the conveying device 11, and the inclined plate (conveying path) according to the sliding of the piston rod with respect to the rotary shaft 131 of the inclined plate (conveying path) 13 Turn 13

  The air cylinder 3 has air supply and discharge ports 321 and 322 for supplying and discharging on both sides, and is connected to the air pipes 32 and 33. When the blocking wall is lowered, the transport path (inclined plate) 13 is retracted, and the blocking wall blocks the transport devices. The roles of the plate members 13a and the plate members 13b constituting the transport path (inclined plate) 13 are as described above with reference to FIGS. 2A and 2B. These plate members may be a single plate as a plate-like body as described above.

  FIG. 3B is a perspective view for explaining another embodiment of the transport path having a slope according to the second embodiment of the present invention described in FIG. 3A. In the configuration shown in FIG. 3B, the same reference numerals as used in FIG. 3A indicate the same objects. In FIG. 3B, the characteristic point largely different from the previous embodiment is that the inclined conveyance path 13 is provided on the lower side (downstream) conveyance device 12 side as a retraction mechanism of the conveyance path (inclined plate) 13. It is in.

  A piston rod 31 extending from the air cylinder 3 is attached at a predetermined position 311 on both sides of the plate 13b to support the entire transport path (inclined plate) 13 so that it can be retracted if necessary. At the time of retraction, the transport path (inclined plate) 13 is rotated about the rotation shaft 132 as indicated by an arrow a. Further, when the transport path (inclined plate) 13 is rotated and retracted, it is rotated downward about the rotation shaft 132 to which the plate material 13b is attached, and is opposed to the transport path 111 of the upper plate material 13a. The side moves in the direction of the arrow a.

  One end of the air cylinder 3 is swingably attached to the fixed portion 34 on the side plate of the conveying device 11, and the conveyance path (inclined plate) according to the sliding of the piston rod with respect to the rotary shaft 131 of the conveyance path (inclined plate) 13 Turn 13

  The air cylinder 3 is provided with air supply and discharge ports 321 and 322 for supply and discharge, and is connected to the air pipes 32 and 33. When the blocking wall is lowered, the transport path (inclined plate) 13 is retracted, and the blocking wall blocks the transport devices. Thus, the detection pin 41 detects and rotates the lowering operation of the blocking wall, and the air switching switch 42 can be operated to retract the transport path 13.

  FIG. 3C is a perspective view for explaining still another embodiment of the inclined conveyance path according to the second embodiment of the present invention described in FIG. 3A. In the configuration shown in FIG. 3C, the same reference numerals as used in FIG. 3A indicate the same objects. In FIG. 3C, the characteristic point largely different from the previous embodiment is that the inclined conveyance path 13 can freely rotate back and forth and left and right as the rotation shaft 133 toward the upper side (upstream) conveyance device, for example, a universal joint (Universal joint) is the point where it is connected.

  In FIG. 3C, a piston rod 31 extending from the air cylinder 3 is attached to a predetermined position 311 on one side of the plate 13a, supports the entire transport path (inclined plate) 13, and can be retracted if necessary.

  One end of the air cylinder 3 is swingably attached to the fixed portion 34 on the side plate of the conveying device 11 and the inclined plate (conveying path) according to the sliding of the piston rod with respect to the rotation shaft 133 of the inclined plate (conveying path) 13 Turn 13 At the time of retraction, the inclined plate (conveying path) 13 is rotated about the rotation shaft 132 as indicated by an arrow a, and is retracted (toward the front side in the illustrated example) as indicated by an arrow b. Thus, the detection pin 41 detects and rotates the lowering operation of the blocking wall, and the air switching switch 42 can be operated to retract the transport path 13.

  Although the detection pin 41 is a rod-like one, the tip of the detection pin may be shaped into a curved shape, or a curved elastic body (for example, a tube or a balloon) may be used. It may be added or covered. In this way, when the blocking wall at the time of return rises, the tip of the detection pin is prevented from being caught by the blocking wall, and the air flow can be switched smoothly to cope with it, contrary to the lowering time.

  Although not shown in the drawings, similarly, on the opposite side, the descent of the blocking wall is detected and the conveyance path (inclined plate) 13 is retracted and driven from both ends of the conveyance path (inclined plate) 13 become. In addition, when it is possible to control physically on only one side by the relationship between the members of the transport path and the strength, it is not necessary to provide the same configuration at both ends.

  FIG. 4 is a view for explaining a pneumatic pressure supply route in the case where an air cylinder is used for the shutoff mechanism of the transport path according to the second embodiment of the present invention.

  The air cylinder 3 illustrated in FIGS. 3A and 3B may be provided on both sides of the transport device or at the lower center of the transport path, or may be on one side as long as the stiffness of the transport path (inclined plate) is high. As an example provided in an overlapping manner, in FIG. The distinction between the pipes and the like corresponding to the air cylinders 3a and 3b will be described below with reference to symbols a and b. The cylinder 3 shown in FIG. 3C may be installed on the front side or the opposite side of one side, and only one of the air supply routes described below in FIG. 4 may be used.

  The air cylinders 3a and 3b and the detection mechanism 4 for the blocking wall are connected to an air supply source 39 by an air supply pipe. From the air supply source 39, air is supplied to the air cylinders 3a and 3b through the air switching device 38, the air branch supply device 36, and the air branch supply device 37 through the pipes 32a, 33a, 32b, and 33b. The air is supplied to the air changeover switch 42 from 43. In the example shown in FIG. 4, the air switch 38 supplies air to the left air supply / discharge ports 321a and 321b of the air cylinders 3a and 3b, and the piston rods of the air cylinders 3a and 3b are turned to the right, that is, FIGS. As shown, it supports the inclined plate 13 as a transport path disposed in the gap.

  Here, when the detection pin 41 of the detection mechanism 4 of the blocking wall detects the lowering of the blocking wall and pivots downward, the air changeover switch 42 is switched to connect the air piping 43 and the air piping 44 and the air piping 44 Air pressure is applied to the air switch 38, and the air switch 38 switches the air supply to the right side in the drawing. Accordingly, the air supply / discharge to each air cylinder 3a, 3b is reversely operated, and the piston rods 31a, 31b operate in the direction to be stored on the left side. That is, the air cylinder of FIG. 3A to FIG. 3C operates in the reverse direction to rotationally move the transport path (inclined plate) 13 downward and retract it from the gap. In this case, the transport path (slanted plate) may be rotated and retracted faster by its own weight by removing the air.

  On the other hand, at the time of restoration, the air pressure applied to the air switching device 38 is released by returning the detection pin 41 to the original state, and the air route is returned to the original state, and the inclined plate (conveying path) 13 is at the original position by the operation of the air cylinders 3a and 3b. Return to

  In addition to the return, the air switch 38 may be driven by providing the release switch 45.

  The detection pin 41 is a thin rod-like pin such as a wire, and even if the blocking wall has an obstacle detection function, the detection pin itself is not affected. Moreover, if it is a thing which does not affect detection of the obstacle of a blocking wall, it is not necessarily restricted to a rod-shaped pin, and if it is a thing which detects blocking operation, various shapes and structures can be considered .

  Further, in the embodiment of the present invention described with reference to FIGS. 3A to 3C and FIG. 4, the configuration should not be limited to the illustrated configuration, and the illustrated configuration includes schematic ones and their dimensions, etc. It should not be interpreted as limited to.

  In the illustrated example, air cylinders are disposed on both sides of the transport path as a retracting structure of the transport path 13 provided in the gap, but in consideration of mechanical operation and mechanical strength, the inclined plate 13 The air cylinder may be provided only at the central part or one side of the housing. In addition, although the air supply and discharge port of the air cylinder is configured to assume both the evacuation operation and the return operation, the lateral pressure of the piston rod by the air cylinder is applied in one direction, and the conveyance path is It may be evacuated. In the case of only the evacuation operation in this emergency, the return may be performed manually. In the case of this manual return, the air supply to the air cylinder 3 may be only the supply route in the direction in which the conveyance path 13 is pressed and maintained. In the case of retracting the conveyance path, only the air pressure is released.

  Since the remaining time in the existing air wiring (piping) can be continuously maintained for a predetermined time from the detection of the shutoff operation until the evacuation control of the transport path is completed, the air supply source (for example, air tank) 39 can be maintained. Alternatively, air remaining inside the air wiring (pipe) can be used. In addition to the air supply source (air tank) 39, an auxiliary air supply source (auxiliary tank) may be further provided. At the time of operation, it is necessary to maintain the conveyance path. Even if the air supply pressure of the air supply source (for example, air tank) 39 is lowered, the conveyance is performed by supplying air by the air supply source 39 and the auxiliary air supply source. The road can be maintained continuously, and air control can be performed at the time of retraction. Furthermore, the air pressure of each of the air supply source 39 and the auxiliary air supply source may be maintained by a compressor to prevent a drop in air pressure.

  Also, in place of the air cylinder 3 shown in FIGS. 3A to 3C, a spring material is used to maintain the lateral pressure of the transport path 13 in one direction, and the stopper is removed when the blocking operation of the blocking wall is detected. You may An embodiment using a spring, a weight or the like as an example of the spring material will be described later.

  Using an air cylinder, a spring material, a weight or the like has an advantage of being able to cope with a power failure such as a power failure.

  Also, in place of the air cylinder 3, the lateral pressure rod (equivalent to a piston rod) may be extended and contracted by motor drive or the like. Alternatively, the motor may be driven using a pinion and rack gear combination. As a drive power supply for driving the motor or the like, an emergency power supply (also called an emergency power supply, a standby power supply, or an uninterruptible power supply UPS) may be used in the event of a power failure such as a disaster or an emergency. When an emergency power supply or the like is used as the evacuation mechanism, the detection mechanism 4 may be a drive circuit by power supply and may transmit the detection result to the evacuation mechanism through a signal line.

  Also, prior to the retraction operation of the transport path (inclined plate) 13 accompanied by the operation of the blocking wall, the upstream transport path 111 is reversely rotated or / and the transported object is temporarily retained on the upstream side with the start of the retraction operation. , May be driven to switch. This makes it possible to prevent the inflow of the conveyed article from the upstream conveyance path 111 during the retraction operation of the conveyance path (inclined plate) 13.

  Further, the downstream conveyance path 121 may be continuously driven for a predetermined time along with the blocking operation of the blocking wall. Thereby, retention of conveyance articles before and behind conveyance path (inclined plate) 13 can be prevented.

  As a drive power supply for the conveyance path (inclined plate) 13, a drive power supply for the conveyance path 111, and the conveyance path 121, etc. These power supplies for emergency use, emergency power supplies (emergency power supplies, standby power supplies, An uninterruptible power supply UPS can also be used.

  In the embodiment of the present invention described with reference to FIGS. 3A to 3C, the blocking wall is of the falling type, but in the case of detecting the blocking operation in advance, the blocking wall is below the floor or the like. Even if it is a type which accommodates the blocking wall and the blocking wall rises upward from the floor surface etc., it can be configured similarly. In the case of the type in which the blocking wall is elevated, a detection mechanism for detecting the blocking operation of the blocking wall may be provided below the transport path of the transport device. In addition, the blocking wall may be accommodated in a lateral wall surface or the like, and may be a sliding door type, a bellows type (accordion type), or the like that slides from the lateral direction at the time of the blocking operation. In the case of the blocking wall which performs the blocking operation from the lateral direction, the detection mechanism may be disposed in parallel in the transport path. Furthermore, it may be a type of door that opens and closes like a hinged door. In the case of the door to be opened and closed, the blocking distance (interval) for blocking the transport path may be determined in consideration of the width (range) of the opening and closing operation of the door.

  The same applies to the following, and the embodiments of the present invention will be described with the type that descends as the blocking operation of the blocking wall, but the embodiments are not limited to the operating directions of these blocking walls.

  FIG. 5 is a view for explaining the configuration of the main part of a blocking mechanism of a conveyance path according to a third embodiment of the present invention.

  In FIG. 5, a spring 5 is provided to bias the inclined transport path 13 in the gap between the transport devices, and one end 52 of the spring 5 is slidably attached to the guide plate 53, the spring It is pulled by 531 and 532, and is fixed and maintained by the stop pin 54, and the other end is attached to the side wall 51 of the transport path 13.

  On the other hand, the detection mechanism 4 for detecting the blocking operation of the blocking wall includes a detection pin 41 for detecting the lowering of the blocking wall, and a wire 56 is connected to the detection mechanism 4 instead of the air changeover switch. The wire 56 is connected to the stop pin 54 through the piece 55.

  When the blocking wall is lowered and the detection pin 41 detects that the blocking wall is lowered, the detection mechanism 4 rotates and pulls the wire 56. The tension generated in the wire 56 pulls out the stop pin 54, and one end 52 of the spring 5 is pulled leftward in the drawing by the springs 531 and 532, and the transport path 13 having inclination is rotated leftward from the gap and retracted. . In this way, it is possible to prevent damage or the like caused by lowering of the blocking wall.

  FIG. 6 is a view for explaining the main configuration of a blocking mechanism of a conveyance path according to a fourth embodiment of the present invention.

  In FIG. 6, a spring 6 is provided to bias the inclined transport path 13 in the gap between the transport devices, and a weight 621 is attached to one end 62 of the spring 6, and the guide plate 63 is vertically It is slidably mounted in the direction, fixed and maintained by the stop pin 64, and the other end is mounted on the side wall 61 of the transport path 13.

  On the other hand, a detection mechanism for detecting the lowering of the blocking wall is the same as that shown in FIG. 5 and is not shown, but a wire is connected to the stop pin 64 via the pieces 65 and 66.

  When the blocking wall is lowered and detected, the detection mechanism rotates and pulls the wire. The tension generated in the wire causes the stop pin 64 to come off, or rotates in the direction of the spring 6 and descends downward along the guide plate 63 by the weight of the weight 621 to connect the other end of the spring 6. The side wall 61 of 13 is pulled leftward in the drawing, and the transport path (inclined plate) 13 retracts from the gap. In this way, it is possible to prevent damage or the like caused by lowering of the blocking wall.

  FIG. 7A is a side view for explaining the main configuration of a blocking mechanism for a conveyance path according to a fifth embodiment of the present invention.

  In FIG. 7A, the transport device 11 and the transport device 12 are disposed with a predetermined gap at the boundary of the blocking facility 2, and the transport path 13 in which the gap between the transport devices is inclined is disposed to be able to rotate and retract. The conveying device 11 and the conveying device 12 have different heights, and the conveyance path formed between the devices is formed by the conveyor 111 provided in the conveyance device 11, the conveyance path (inclined plate) 13, and the conveyor 121 disposed in the conveyance device 12. Ru.

  The roller retracting structure involved in the detection of lowering of the blocking wall in FIG. 7A differs from FIGS. 3A to 3C described above in that the mechanical retraction is performed without using the air supply / discharge mechanism.

  As a mechanism for detecting the lowering of the blocking wall 22, a wheel 72 is used as a rotating body in contact with the side surface of the blocking wall 22, and a wheel 72 and a free wheel 73 are fixed to both ends of the arm 71. The idler 73 side of the arm 71 is rotatably attached to the transfer device 11 side, and is pressed to the wheel 72 side by a pressing spring 76. A stopper 78 is provided to prevent the entire arm 71 from moving downward due to the force acting downward as the wheel 72 slides on the wall of the blocking wall 22.

  It can be said that the mechanism for detecting the lowering of the blocking wall 22 is configured by the wheel 72, the arm 71, the idle wheel 73, the pressing spring 76 and the like.

  On the other hand, a weight 77 having a predetermined weight is attached to the other end of the transport path (inclined plate) 13 on the side wall of the transportable fixing member 79.

  In addition, a wire 75 is attached around the idler wheel 73 between an end 762 of the fixing member 79 to which the weight 77 is attached and the rotation axis of the wheel 72.

  When the wheel 72 slides and rotates the wall of the blocking wall 22 as the blocking wall 72 descends, the wire 75 is wound around the wheel shaft, and the weight 77 is pulled up via the idler wheel 73. Along with this, the fixing member 79 is rotated, and the transport path (inclined plate) 13 is rotationally moved about the upper rotation shaft (not shown) and retracted from the gap.

  According to the present invention, since the wall surface of the blocking wall is used to detect the blocking operation, the automatic stopping function by the obstacle detection on the lower surface of the blocking wall is not affected with the lowering of the blocking wall. That is, the fixing member 79 is rotated in accordance with the upward movement of the weight 77, and the transport path (inclined plate) 13 is rotated and retracted from the gap to a predetermined position. In this way, it is possible to prevent damage or the like caused by lowering of the blocking wall.

  Although automatic retraction is possible by retraction and return by vertical movement of the weight 77, the weight can be eliminated by using the timing belt instead of the wire, and the reciprocating movement of the timing belt by the rotation of the wheel 72 is also possible. It is possible to return.

  Although not shown in the drawings, similarly, on the opposite side, the descent of the blocking wall 22 is detected to retract the transport path (inclined plate) 13 and driven from both ends of the transport path (inclined plate) 13 It will be. In addition, when it is possible to control physically on only one side by the relationship between the members of the transport path and the strength, it is not necessary to provide the same configuration at both ends.

  FIG. 7B is a side view illustrating the configuration of the main part of another embodiment of the blocking mechanism of the transport path according to the fifth embodiment of the present invention described in FIG. 7A. In the configuration shown in FIG. 7B, the same reference numerals as used in FIG. 7A indicate the same objects. In FIG. 7B, the feature point largely different from the previous embodiment is that the support arm (support member) 71 is pulled instead of the lateral pressure spring 76 of the arm 71 supporting the rotating body 72 which detects the lowering of the blocking wall 22. A spring 761 is provided at the central portion 762 of the support arm 71.

  At a normal time when the blocking wall 22 does not operate, the arm 71 is biased downward by a tension spring (spring) 761 so that the wheel 72 is at a predetermined position on the blocking facility 2 side. When the blocking wall 22 is lowered, the wheel 72 comes in contact with the wall of the blocking wall 22 with the lowering motion, and the rotation of the wheel 72 causes the falling of the blocking wall 22 to be detected. The tensioning spring (spring) 761 maintains the wheel 72 as the lowering detection means, and maintains the retraction operation of the transport path by the rotation operation of the wheel 72 accompanying the lowering of the blocking wall.

  Although the example which used the spring (spring) for maintenance of a conveyance way and retreat operation was shown above, it is not limited to this, using a spring material corresponding to movement at the time of maintenance and retreat movement of a conveyance way normally. Can.

  7A and 7B, the spring members (springs 76 and 763) can be omitted when the weight of the wheel 72 is equal to or more than a certain weight.

  FIG. 8A is a side view illustrating the configuration of the main part of a blocking mechanism of a conveyance path according to a sixth embodiment of the present invention.

  In FIG. 8A, the transfer device 11 and the transfer device 12 having a level difference are disposed with a predetermined gap at the boundary of the blocking facility 2, and the transfer path 13 in which the gap between the transfer devices is inclined is disposed to be able to rotate and retract. There is. A conveyance path (conveyor) 111 disposed in the conveyance device 11, a conveyance path (inclined plate) 13, and a conveyance path (conveyor) 121 disposed in the conveyance device 12 are formed as the conveyance path for conveying an article or the like.

  8A is different from FIGS. 3A to 3C as the retracting structure of the transport path (inclined plate) 13 in the gap with the detection of the lowering of the blocking wall in FIG. 8A, the mechanical feeding is performed without using the air supply / discharge mechanism. It is.

  Furthermore, the notable feature point is that the rotating body such as a wheel or the protrusion 23 is provided on the side of the predetermined position from the lower side of the blocking wall 22. When the blocking wall 22 descends as indicated by an arrow a, the rotating body or the projection 23 is detected to retract the transport path (inclined plate) 13. In the illustrated example of the rotating body or the projection 23, although it is shown as a rotating body, it may be anything that can be caught and pushed by the tip of the member 81 for detecting the movement of the blocking wall 22, Good.

  In FIG. 8A, the descent detection of the blocking wall 22 and the retraction of the transport path (inclined plate) 13 are performed in the illustrated example using a reverse U-shaped member 81, with the tip of the upper side serving as the detecting portion of the rotating body or protrusion 23; The other end of the member is rotatably attached to the member attachment portion 82 as a rotating shaft 83. The upper side is a drive bar of the member 81. The lower end of the member 81 is attached to the side wall 85 of the transport path (inclined plate) 13, and a pressing spring 86 is attached to the opposite end 84 side. Under normal conditions where the blocking wall 22 is stored, the reverse U-shaped member 81 maintains the conveying path (inclined plate) 13 at a predetermined position by the pressing force of the pressing spring, and the conveyor 111 of the conveying device 11 and the conveying path (inclined plate 13) The conveyance path by the conveyor 121 of the conveyance device 12 is formed. In this case, the lowering force of the blocking wall is assumed to be sufficiently larger than that of the pressure spring.

  Also, instead of the pressing spring 86, a spring may be provided between the rotating shaft 83 and the end 84 in the direction opposite to the direction of the arrow c to maintain the operating position of the transport path 13. Moreover, it can replace with these springs and can also be made to pull with a weight. Further, depending on the balance of the pressing force of the pressing spring 86, a stopper for positioning may be provided.

  When the blocking wall 22 is lowered, the rotary body or the projection 23 disposed on the side of the blocking wall 22 pivots the upper side downward about the rotation shaft 83 of the reverse U-shaped member 81. Along with this, the lower side also turns against the spring 86, and the transport path (inclined plate) 13 is retracted from the gap as shown by the dotted line in the figure.

  Thus, the transport path (inclined plate) 13 can be rotated and retracted from the gap to a predetermined position to prevent damage or the like due to the lowering of the blocking wall.

  Although not shown, the same configuration is also provided on the side opposite to the fire protection shutter, and it is driven from both ends of the conveyance path (inclined plate) 13. In addition, when it is possible to control physically on only one side by the relationship between the members of the transport path and the strength, it is not necessary to provide the same configuration at both ends. In addition, as a member having a U shape shown in the drawing formed of an upper side, a lower side and a side connecting the members, it may be made by integral molding.

  FIG. 8B is a side view illustrating the configuration of the main part of another form of the blocking mechanism of the transport path according to the sixth embodiment of the present invention described in FIG. 8A. In the configuration shown in FIG. 8B, the same reference numerals as used in FIG. 8A indicate the same objects. In FIG. 8B, the feature point significantly different from the previous embodiment is that a fulcrum serving as a rotation operation of the upper side member for detecting the lowering operation of the blocking wall is provided at the center of the upper side.

  In FIG. 8B, the rotation shaft 831 is held at the central portion of the member 81 on the upper side for detecting the downward movement of the blocking wall 22, and is rotatably attached to the mounting portion 821. The upper side is a drive bar of the member 81. When the tip end of the upper side member 81 contacts the rotary body or the projection 23 of the blocking wall 22, the other end of the upper side pivots upward and the lower side pivots against the pressure spring 86 and the inclined plate 13 It will be evacuated.

  As in FIG. 8A, in FIG. 8B as well, in place of the pressing spring 86, a spring is provided between the upper portion of the member 81 and the end 84 to pull in the opposite direction to the direction of the arrow c. Thus, the position of the transport path 13 at the time of operation can be maintained. Moreover, it can replace with these springs and can also be made to pull with a weight. Further, depending on the balance of the pressing force of the pressing spring 86, a stopper for positioning may be provided.

  In the embodiment shown in FIG. 8B, the rotary shaft 831 is provided at the center of the upper side, but the rotary shaft has a fulcrum regardless of the case where the rotary shaft 83 is provided at the other end of the upper side described above with reference to FIG. The principle of leverage to give movement can be used. That is, in any of the embodiments, the one end for detecting the lowering of the blocking wall is provided with a fulcrum for giving a rotational operation, and the other end performs the retraction operation of the transport path.

  As described above with reference to the respective drawings, it is possible to safely lower the blocking wall such as a fire protection shutter or the like at the time of disaster or the like without damaging or damaging the conveying device or the like. In the examples described with reference to FIGS. 1 to 8, the shutoff mechanism of the transport path does not depend on the electric power of the electric system, but is air driven or mechanically driven, and can cope with a power failure.

  In addition, in equipment that can ensure an electrical system at the time of a disaster such as a fire, instead of the air drive described in FIGS. 3A to 3C and FIG. It is also possible to retract a certain transport path.

  Each embodiment described in the respective drawings shows an example, and in the relationship between the transport path and the blocking wall, if it is a configuration that can be similarly applied as the retraction and blocking mechanism of the transport path, it is illustrated as the transport path. The present invention is not limited to the belt conveyor type, and may be of a roller conveyor configuration, by other conveying means, or the like.

  In each of the embodiments described above, it is possible to further include means for removing the transported item and / or a part of the transporting route. The means for removing the transfer object may be any mechanism for removing the transfer object on the transfer path within a range that hinders the blocking operation of the blocking wall. The mechanism may be any mechanism as long as it has a function of delivering or discharging the conveyance path by detecting the conveyance object on the conveyance path.

  In each of the embodiments described above, the retraction mechanism is described as an example of retracting to the conveyance device 11 side, but may be configured to retract to the conveyance device 12 side, and is not limited to the retraction direction.

  As described above with reference to the respective drawings, it is possible to safely shut off the breaking wall such as a fire protection shutter or the like at the time of a disaster or the like without damaging or damaging the transporting device or the like. Further, the shutoff mechanism of the transport path can be driven by the emergency power supply even in the event of a power failure or power shutoff, and can be handled independently of the electric power by the air drive or the mechanical drive.

  Further, the present invention is not construed as being limited to the arrangement configuration, each device structure, dimensions, and the like given as an example of illustration. In addition, parts not directly related to the present invention may be omitted, and should not be interpreted as being limited to the illustrated example.
