  In order to facilitate understanding of the present invention, first, the background of the present invention will be described. In the case of buildings, etc., when they are constructed beyond a predetermined floor area, in order to respond to disasters such as fires and earthquakes, for example, the Fire Service Act quotes the Building Standards Act and fire prevention such as fire shutters. Facilities are to be provided. Buildings include storage warehouses for articles, buildings such as manufacturing facilities, and transportation facilities.

Specifically, for fire prevention compartments in buildings, for example, floor area ≧ 1,500 m ² etc., installation of fire prevention equipment etc. is obligated by predetermined area divisions (Building Standard Act Enforcement Ordinance Article 112), fire fighting It is also cited in the law.

For example, FIG. 31 is a diagram for explaining the relationship between a transfer device as a background art and a shut-off facility (hereinafter also referred to as a shut-off wall or a shut-off facility) that shuts off a predetermined section, such as fire prevention equipment, as shown in FIG. In addition to the building pillars 17 and the like, a fire prevention facility 15 including facilities for guiding a barrier wall (fire shutter, etc.) is provided in the building having a larger area than the prescribed size (the barrier wall itself). Is not shown). When the transfer device 1 is disposed across the fire prevention equipment 15, if the barrier wall descends along the guide of the fire prevention equipment 15 when a disaster such as a fire occurs, the corresponding part of the transport path under the barrier wall or the barrier wall It will be damaged. Further, when the obstacle detection function is provided on the lower surface of the blocking wall, there is a problem that the conveyance device is stopped by detecting it and the fire prevention function is not performed.

  The present invention focuses on detecting the lowering of the blocking wall in advance, and features a blocking mechanism that detects the lowering of the blocking wall and retreats the corresponding portion of the conveyance path below the blocking wall.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view for explaining a blocking mechanism of a transport device according to an embodiment of the present invention, FIG. 2A is a plan view, and FIG. 2B is a side view. In each figure, the same symbol indicates the same object.

  In FIG. 1, as a blocking operation, for example, in a place where the facility 5 that drops and blocks a predetermined section is disposed, the transfer device 1 includes a transfer device 11 and a transfer device 12. Is provided with a gap. A roller 13 that forms a conveyance path is disposed in the gap. A guide rail 51 is arranged in the shut-off facility 5 to guide when the shut-off wall descends. In the present invention, the barrier wall descending along the guide rail 51 is detected in advance, and the roller 13 serving as a conveyance path in the gap between the conveyance devices is retracted. A detection mechanism 4 for detecting the blocking wall is provided. The detection mechanism 4 includes a blocking wall detection unit 41 and an air changeover switch 42. Air supply / discharge air pipes 43 and 44 are attached to the air changeover switch 42 of the detection mechanism 4. The detection unit 41 of the detection mechanism 4 only needs to detect the blocking operation of the blocking wall. For example, a detection pin (also called a bar switch) can be used. Hereinafter, in the present embodiment, the detection pin 41 will be described. The detection pin 41 is attached so as to cross the guide rail of the blocking wall. When the detection pin 41 rotates downward as the blocking wall is lowered, the air changeover switch 42 is operated and the roller 13 is retracted.

  The roller 13 is attached to one end of the rotating side plate 2, the piston rod 31 of the air cylinder 3 is attached to the other end of the rotating side plate 2, and the rotating side plate 2 with the rotating shaft 21 as an axis is indicated by an arrow a. It can be rotated.

  One end of the air cylinder 3 is attached to the fixed portion 34 so as to be swingable with respect to the side plate of the transport device, and rotates the rotating side plate 2 with respect to the rotating shaft 21 of the rotating side plate 2 according to the movement of the piston rod 31.

The air cylinder 3 is provided with air supply / exhaust ports 321 and 322 on both sides, and is connected to the air pipes 32 and 33. When the blocking wall is lowered, the roller 13 is retracted, and the blocking wall can be lowered with respect to the conveyance path to be blocked. That is, the air cylinder 3 constitutes an urging mechanism (urging means) that urges the conveyance path (roller) 13 to rotate through the piston rod 3 1.

  As shown in the plan view of FIG. 2A, air cylinders 3a and 3b are provided as urging mechanisms for urging the rollers 13 to rotate downward on both sides of the conveyance path including the roller conveyor 111. Air pipes 32a, 33a, 32b, 33b for supplying and discharging air are connected to the air cylinders 3a, 3b, respectively, and are controlled by a common air supply route as will be described later.

As shown in the side view of FIG. 2B, air supply / discharge air pipes 43 and 44 connected to the air changeover switch 42 of the barrier wall detection mechanism 4 described above are air supply sources of the air cylinders 3a and 3b. The air changeover switch 42 is operated by driving the detection pin 41 of the detection mechanism 4 to perform air control of the air cylinders 3a and 3b. This air control will be described with reference to FIGS. 3A to 5.

  2A and 2B, the gap A including the roller 13 indicates a clearance that takes into consideration the operating range of the blocking wall.

  FIG. 3A is a diagram illustrating an air pressure supply route according to an embodiment in which an air cylinder is used as the blocking mechanism of the transport device of the present invention.

  In FIG. 3A, the air cylinders 3a and 3b and the blocking wall detection mechanism 4 are connected to an air gas supply source (for example, an air tank) 39 by an air supply pipe. From the air gas supply source 39, air is supplied to the air cylinders 3a, 3b via the pipes 32a, 33a, 32b, 33b via the air switch 38 and air is supplied from the pipe 43 to the air changeover switch 42. In the illustrated example of FIG. 3, air is supplied to the left supply / exhaust ports 321a and 321b of the air cylinders 3a and 3b by the air switch 38, and the piston rods 31a and 31b of the air cylinders 3a and 3b are moved to the right side, that is, FIG. As shown in FIGS. 2A and 2B, the roller 13 disposed in the gap is pressed in the direction to support.

  Here, when the detection pin 41 of the blocking wall detection mechanism 4 detects the lowering of the blocking wall and rotates downward, the air changeover switch 42 is switched to connect the air pipe 43 and the air pipe 44, and the air pipe 44 is connected. Thus, air pressure is applied to the air switch 38, and the air switch 38 switches the air supply to the right side of the figure. Accordingly, the air supply / discharge to the air cylinders 3a and 3b is reversed, and the piston rods 31a and 31b are moved to the left side. That is, when the air cylinder of FIGS. 1 and 2B operates in the reverse direction, the roller 13 is urged downward, and is rotated and retracted from the gap.

  On the other hand, at the time of recovery, by returning the detection pin 41 to the original state, the air pressure applied to the air switch 38 is released, the air gas route is restored, and the rollers 13 are returned to their original positions by the operation of the air cylinders 3a and 3b. .

  In addition to such a return, a release switch 45 may be provided to drive the air switch 38.

  Although the detection pin is illustrated as the detection unit 41 of the detection mechanism 4, 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 affected. It will never be done. Further, another embodiment of the detection unit 41 will be described later.

  FIG. 3B is a diagram illustrating an air pressure supply route according to the second embodiment when an air cylinder is used as the blocking mechanism of the transport device of the present invention.

  3B is different from FIG. 3A in that air remaining in the air wiring (piping) is used in place of the air gas supply source (for example, air tank) 39. If the air wiring (pipe) 392 is connected to the air gas supply source 39 from the connection port 393 as an air gas supply and is not connected to the air gas supply source 39, the air wiring (pipe) 392 and / or the existing air wiring The cylinder 3 can be driven because the remaining air in (piping) can be continuously maintained for a predetermined time. Of course, it may be connected to the air gas supply source 39, or may be connected after elapse of a predetermined time.

  FIG. 4 is a diagram illustrating an air pressure supply route according to the third embodiment when an air cylinder is used as the blocking mechanism of the transport device of the present invention.

  4, in addition to the air gas supply source (air tank) 39 to the cylinders 3a and 3b shown in FIG. 3A, an auxiliary air gas supply source (auxiliary tank) 391 is further provided. In order to maintain the conveyance path (roller) 13 in a predetermined state, it is necessary to continuously supply air to the air cylinders 3a and 3b to maintain the air pressure. In FIG. 4, air is supplied from an air gas supply source 39 and an auxiliary air gas supply source 391 in order to maintain the conveyance path (roller) 13 by the piston rods 31a and 31b in the air cylinders 3a and 3b. Even if the air supply pressure 39 decreases, the conveyance path 13 can be maintained continuously during normal use, and air control during retraction can be performed. Also, when the transport path 13 is once retracted and restored after being retracted, the air gas supply source is duplicated, so that the restoration operation is ensured. It is also effective when repeatedly performing evacuation and recovery driving as a test operation.

  Further, as shown in FIG. 4, a compressor 390 may be connected to each of the air gas supply source 39 and the auxiliary air gas supply source 391 to prevent the air pressure from decreasing. It is possible to prevent the air pressure from decreasing with the passage of time of the air gas supply source 39 and the auxiliary air gas supply source 391. In the illustrated example, the compressor 390 is provided in common to both the air gas supply source 39 and the auxiliary air gas supply source 391. However, the compressor 390 may be provided separately, or may be provided in either one. . Further, even when the auxiliary tank illustrated in FIG. 3A is not used, the compressor 390 may be connected to the air gas supply source 39.

  FIG. 5 is a diagram illustrating an air pressure supply route according to the fourth embodiment when an air cylinder is used as the blocking mechanism of the transport device of the present invention.

  5 differs from that shown in FIGS. 3A, 3B, and 4 in that an air changeover switch 381 using a solenoid valve in addition to an air changeover switch 382 operated by the detection mechanism 4 is provided in the air supply route. . In addition, although shown as what changes an air route directly from the detection mechanism 4 not via the air changeover switch 42, you may be via the air changeover switch 42 like FIG. 3A.

  In FIG. 5, the air supplied from the air gas supply source (air tank) 39 by the air wiring (air piping) a <b> 1 enters the air changeover switch 382 of the detection mechanism 4. The air output from the air changeover switch 382 is input to the air changeover switch 381 via the air wiring (air piping) a2 or a3. The air changeover switch 381 is provided with a route for allowing the air output a2 or a3 from the air changeover switch 382 to pass through as it is and a route for selectively outputting by the electromagnetic valve. The solenoid valve provided in the air changeover switch 381 outputs air in one direction while power is supplied through the electric wiring 383.

  In the example illustrated in FIG. 5, as the air route of the air changeover switch 381, during the air output of the air changeover switch 382 that operates according to the detection result by the detection mechanism 4, in addition to the route indicated by the broken line a <b> 3, The air route indicated by the solid line during the supply is maintained, and in the case of a power failure or the like in which no power is supplied from the electric wiring 383, the air route is changed to a broken air route.

  Therefore, in the example illustrated in FIG. 5, while the transfer device is normally operated and the normal power is supplied, the air route from the air gas supply source 39 includes, for example, the air wiring (air piping) a1 and the air changeover switch 382. Air (or air pressure) is supplied to the cylinders 3a and 3b via the air wiring (air piping) a2, the air changeover switch 381, and the air wiring (air piping) a4, and the piston rod is maintained to maintain the conveyance path in an operating state. doing.

  In addition, when the detection mechanism 4 detects a blocking wall blocking operation in the event of a disaster such as a fire, the air switching switch 382 is switched, and the air route from the air gas supply source 39 to the air wiring (air piping) a1 and the air switching switch 382 is switched. The air (or air pressure) is supplied to the cylinders 3a and 3b in the direction of retracting the piston rod via the air wiring (air piping) a3, the air changeover switch 381, and the air wiring (air piping) a5 to retract the conveying path. . In this case, it does not matter whether the regular power supply is maintained.

In addition, when a power failure occurs, the solenoid valve of the air changeover switch 381 operates as the power from the power supply line 383 is stopped, and the air route from the air gas supply source 39 to the air wiring (air piping) a1 and the air changeover switch 382, air wiring (air piping) a2, air changeover switch 381, air wiring (air piping) a5, air (or air pressure) is supplied to the cylinders 3a and 3b in the direction of retracting the piston rod, and the conveying path is retracted. Let In this case, it is not related to the presence or absence of the blocking operation of the blocking wall.
When the power supply is restored, the solenoid valve of the air changeover switch 381 is restored and the air circuit is returned to the normal state. That is, the transport path is restored.

  Note that the air route initialization (initial setting) in the air changeover switch 382 and the air changeover switch 381 may be performed by the release switch 45 via the control line SS as described with reference to FIG. 3A.

  Further, the example illustrated in FIG. 5 is described as an example in which the air changeover switch 382 and the changeover switch 381 that directly change the air route from the detection mechanism 4 are described, but the present invention is not limited to this, and FIG. 3B and FIG. 4 may be applied. Further, the auxiliary air gas supply source (auxiliary air tank) 391, the compressor 390 and the like shown in FIGS. 3A, 3B, and 4 may be provided.

  The air wiring (air piping) used in the air circuit and air route described in the above embodiment is preferably made of non-combustible material and / or metal pipe from the viewpoint of disaster prevention against disaster such as fire. As the metal tube, a copper tube may be used considering the ease of wiring and the ease of bending.

Moreover, in the said embodiment, you may drive-control the piston rod of the air cylinder 3 by starting based on the notification information from alarm devices, such as a fire alarm and a smoke detector.

  As described above, in the embodiment of the present invention described with reference to FIGS. 1 to 5, it should not be limited to the illustrated configuration, and the illustrated one includes a schematic diagram and is limited to its dimensions and the like. Should not be done. In the illustrated example, the air cylinders are disposed on both sides of the conveyance path as the retraction structure of the roller 13 provided in the gap. However, if dynamic operation and mechanical strength are considered, An air cylinder may be provided only on the side surface. In addition, the air supply / exhaust port of the air cylinder is configured assuming both retraction and return operations, but only supports retraction operation that discharges air in one direction in an emergency, and return is performed manually. It may be. Moreover, although the roller conveyor was demonstrated to the example as a conveyance path, it is not limited to this roller conveyor, You may apply in the thing of a belt conveyor structure, and another conveyance means.

  In the embodiment of the present invention, the type in which the barrier wall is lowered is shown, but the barrier wall is stored under the floor and the barrier wall is raised from the floor surface or the like.

Furthermore, a door type that opens and closes like a hinge door may be used. In the case of the door that opens and closes, the blocking distance (interval) that blocks the conveyance 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 each embodiment will be described with the type of a descending type as a blocking operation of the blocking wall, but is not limited to the direction of operation of these blocking walls.

  FIG. 6 is a perspective view for explaining a blocking mechanism of the transport device according to the second embodiment of the present invention.

A spring member 30 that pulls the rotating side plate 2 in the direction of rotation is attached between the two. When the rollers 13 are in an operating state by connecting the conveying devices and serving as a conveying path, the piston rod 31 of the air cylinder 3 presses and maintains the conveying path against the tensile force of the spring member 30. When the detection mechanism 4 detects a blocking wall blocking operation, the air switch is switched by the changeover switch 42, and the piston rod 31 of the air cylinder 3 moves and urges the conveying path 13 in the retracting direction. At the same time, the spring member 30 is pulled.

  In the present invention according to FIG. 6, when the force urging the retracting drive of the conveyance path by switching the air supply route to the air cylinder 3 is weak, for example, even when the air pressure is reduced, the spring member 30 provided together with the air cylinder 3 is switched. It can be completely retracted by the pulling force (shrinking force). In addition, even when retracting (falling) due to the weight of the conveyance path, the spring member 30 can be provided together so that it can be completely retracted by its tensile force (shrinking force).

  FIG. 7 is a perspective view for explaining a blocking mechanism of the transport apparatus according to the third embodiment of the present invention.

  7 differs from that described in FIG. 1 as an urging mechanism (retraction mechanism) for retracting the conveyance path (roller) 13 in addition to air driving by the air cylinder 3 (for example, a belt member, (A string-like member, a wire member, or the like, also simply referred to as a wire) 302 and a weight 304 are provided.

  In FIG. 7, the other end side where the piston rod 31 of the air cylinder 3 is attached to rotate the rotating shaft 21 of the rotating side plate 2 to which the conveyance path (roller) 13 is attached, from the end portion 303 to the fixed portion 34. A wire member 302 is stretched between the side and the piece member 305, and a weight 304 is attached via the piece member 305. When the rollers 13 are in an operating state by connecting the conveying devices and serving as a conveying path, the piston rod 31 of the air cylinder 3 presses and maintains the conveying path against the tensile force generated by the wire member 302 and the weight 304. When the detection mechanism 4 detects a blocking wall blocking operation, the air route is switched by the changeover switch 42, and the piston rod 31 of the air cylinder 3 is moved and urged in the direction of retracting the conveyance path 13. At the same time, the wire member 302 pulled by the weight 304 pulls the rotating side plate 2.

  In the present invention according to FIG. 7, as in the case illustrated in FIG. 6, when the force urging the conveyance path retracting drive by switching the air supply route to the air cylinder 3 is weak, for example, the air pressure decreases. Even when the wire member 302 is present, it can be completely retracted by the tensile force of the wire member 302 and the weight 304 provided therewith. Further, even when the conveyance path is retracted (falls) due to its own weight, the wire member 302 and the weight 304 can be provided together to be completely retracted by the tensile force.

Further, the end portion 303 of the rotating side plate 2 may be directly connected to the weight 304 without passing through the piece member 305.

  8A and 8B show a configuration of a detection mechanism that detects a blocking operation according to an embodiment used in the blocking mechanism of the transport device of the present invention, and FIG. 8B shows an operation corresponding to the blocking operation of the blocking wall. This is to explain the operation corresponding to the return operation of the blocking wall.

  As an example of the detection unit 41 of the detection mechanism 4 that detects the blocking operation of the blocking wall described above with reference to FIG. By using this detection pin, it rotates when at least a part of the blocking wall and / or a wall surface, for example, an end surface (also referred to as a lower surface, a lower side, or an operating side) hits. The changeover switch 42 is driven by this rotation operation. On the other hand, when the transportation apparatus is restored, the blocking wall is returned to the original position. In this case, when it is a detection pin, when the blocking wall is restored to the original position, a force is applied to the detection pin in the reverse direction. At this time, the detection pin may be damaged. 8A and 8B are invented to prevent the detection pins from being damaged.

  In FIG. 8A, the detection mechanism includes a changeover switch (for example, an air changeover switch when an air circuit is used as described above) 42, a detection pin 411, and a flexible member (for example, synthetic resin) that covers the detection pin. Tube material) 412.

8B, the flexible member 412 covering the detection pin 411 follows the operation of the detection pin 411 and is caught when the detection pin 411 is driven to rotate as the blocking operation of the blocking wall 52 as illustrated in FIG. 8B. Since it can be freely deformed, it can be flexibly adapted to the wall surface of the blocking wall. Further, the detection pin can be prevented from being damaged.
Further, while the blocking wall can be prevented damage to the flexible member is shaped to follow the blocking wall instead detect pins to cover the detection pin when restored.
Further, when the detection pin returns to the original position, the changeover switch is restored and the conveyance path returns to the original state.

  FIG. 9 is a configuration diagram of a detection mechanism that detects a blocking operation according to the second embodiment, which is used in the blocking mechanism of the transport device of the present invention.

  9 is different from FIG. 8A in that the detection unit 41 of the detection mechanism is composed of only a flexible member (for example, a tube material made of synthetic resin or the like) 413.

  The flexible member 413 may be a tube-like tube attached like a ring like the previous one, or a rubber-like balloon attached.

With this configuration, the flexible member 413 rotates following the blocking operation of the blocking wall to drive the changeover switch 42. In the illustrated example, the flexible member 413 also serves as a detection pin and can be deformed, so that it can flexibly correspond to the wall surface of the blocking wall. In addition, restoration at the time of restoration becomes easy. That is, the blocking wall shape changes to follow the flexible member is cut off the wall when restored. When the flexible member is returned, the changeover switch is restored and the conveying path is restored to the original state.

  FIG. 10A and FIG. 10B show the block diagram of the detection mechanism which detects the interruption | blocking operation | movement based on 3rd Embodiment used for the interruption | blocking mechanism of the conveying apparatus of this invention, and FIG. It is a figure explaining the corresponding | compatible operation | movement.

  10A, the detection mechanism includes a changeover switch (for example, an air changeover switch when an air circuit is used as described above) 42, a spring member 416 as a detection unit, and a member 415 having an inclination. .

  In the state shown in FIG. 10A, the spring material 416 and the member 415 of the detection unit are in a state in which the spring material 416 presses the inclined member 415 toward the cutoff facility, and the cutoff wall 52 is indicated by an arrow line. When descending, the member 415 is pushed. In other words, the detection unit functions as a slider by the spring material 416 and the member 415.

In FIG. 10B, the member 415 moves against the spring material 416 as indicated by the left arrow line as the blocking wall 52 is lowered, and the changeover switch 42 is operated.
Moreover, member 415 when the blocking wall is restored selector switch returns to the original position is restored.

  FIG. 11 is a configuration diagram of a detection mechanism for detecting a blocking operation according to the fourth embodiment used in the blocking mechanism of the transport device of the present invention.

  8A to 10B described above show an example in which at least a part of the blocking wall is directly detected as the detection unit of the detection mechanism, but in FIG. 11, the operation of the wall surface of the blocking wall is detected. It is a thing.

  In FIG. 11, the detection mechanism includes a changeover switch (for example, an air changeover switch when an air circuit is used as described above) 42 and a detection pin 411. On the other hand, the blocking wall 52 is provided with a protrusion 53 on the wall surface.

As illustrated in FIG. 11, when the blocking wall 52 performs a blocking operation in the direction indicated by the arrow, the projection 53 of the wall surface of the blocking wall hits the tip of the detection pin 411 of the detection mechanism. The detection pin 411 of the detection mechanism is pushed by the protrusion 53 and rotates in the direction indicated by the arrow, thereby driving the changeover switch 42.
Further, when the detection pin of the detection mechanism returns to the original position, the changeover switch is restored as in the previous case.

  As described with reference to FIGS. 8A to 11, various configurations are shown as the detection unit of the detection mechanism that detects the movement of at least a part of the barrier wall or the wall surface. However, the obstacle is detected as the barrier wall moves. Even if it has the function to perform, it should just detect and move with a pressing force less than the pressing force detected as an obstacle. In other words, even when there is a pressure switch or the like that detects an obstacle on at least a part of the blocking wall or the wall surface, the detection mechanism may be made operable with a pressing force that does not activate it. In addition, as a detection mechanism, a mechanism that uses an air circuit to switch the air route is described as an example of detecting the physical contact with the blocking wall. However, as described later, it is detected without contact with the blocking wall. You may do. For example, a light detection mechanism, a sound wave detector, or a wireless device may be used. In the case of these non-contact detection mechanisms, transmission detection may be performed across the gap in the blocking range of the blocking wall, or reflection may be detected.

  FIG. 12 is a perspective view for explaining a blocking mechanism of the transport apparatus according to the second embodiment of the present invention.

  12 is different from the configuration of FIG. 1 in that a roller 13 disposed in a gap between the transport device 11 and the transport device 12 is slid toward the transport device 11 side. The tip of the piston rod 31 of the air cylinder 3 is fixed to a roller holding member 25 that holds the roller 13. A sliding member 23 is arranged under the roller holding member 25, and when the blocking wall is lowered by sliding in the lateral direction of the arrow line a on the rail 24 arranged under the conveying device 11, the roller 13 is withdrawn. Further, in this case, since a retreat path for the roller 13 is provided, a retreat space can be formed by closing a part of the roller gap of the roller conveyor 11.

  The mechanism for detecting the lowering of the blocking wall is the same as in FIG. 1 and is not shown. When this detection mechanism detects the lowering of the blocking wall, air is supplied from the air pipe 33 instead of the air supply from the air pipe 32 of the air cylinder 3, so that the roller 13 slides to the left in the figure and is retracted from the gap. In this way, it is possible to prevent damage or the like associated with the lowering of the blocking wall.

  In the illustrated example, only one side of the conveyance path is shown as the retracting structure of the roller 13 provided in the gap, but it is provided on both sides and driven synchronously. If dynamic operation and mechanical strength are taken into consideration, a retracting structure in which a drive device is provided only on one side may be used.

  FIG. 13 is a perspective view for explaining a blocking mechanism of the transport apparatus according to the third embodiment of the present invention.

  13 is different from the configuration of FIG. 12 in that a belt conveyor is used for the conveying path of the conveying device 1. The conveying path includes a belt conveyor 112 on the conveying device 1 side, a belt conveyor 113 having a retracting structure from the gap, and a belt conveyor 121 on the conveying device 12 side through the gap.

  The belt conveyor 113 disposed in the gap is formed by arranging two to three rotating bodies that guide the conveyance belt in the horizontal direction in the figure.

  The retracting structure of the belt conveyor 113 is slid to the conveying device 1 side as shown in FIG. The tip of the piston rod 31 of the air cylinder 3 is attached to a roller holding member 25 that holds the belt conveyor 113. A sliding member 23 is arranged under the roller holding member 25, and when the blocking wall is lowered by sliding in the lateral direction of the arrow a on the rail 24 arranged on the lower side of the conveying device 1, the roller 13 is withdrawn. In this case, the retreating path of the retracting conveyor 113 may be provided with a mechanism for adjusting the length of the belt as in the case of the roller conveyor.

  The mechanism for detecting the lowering of the blocking wall is the same as in FIG. 1 and is not shown. When the detection mechanism detects the lowering of the blocking wall, air is supplied from the air pipe 33 instead of the air supply from the air pipe 32 of the air cylinder 3 so that the roller 13 is slid to the left in the figure and retracted from the gap. In this way, it is possible to prevent damage or the like associated with the lowering of the blocking wall.

  Further, the slider bed may be retracted in place of the central roller of the belt conveyor.

  In the illustrated example, as the retracting structure of the belt conveyor 113 provided in the gap, only one side of the conveyance path is shown, but it is provided on both sides and driven in synchronization. If dynamic operation and mechanical strength are taken into consideration, a retracting structure in which a drive device is provided only on one side may be used.

  FIG. 14 is a perspective view for explaining a blocking mechanism of the transport apparatus according to the fourth embodiment of the present invention.

  In FIG. 14, the belt conveyor is used for the conveyance path like the structure shown in FIG. As a conveyance path having a retraction mechanism, a belt conveyor 114 having a retraction structure is disposed in a gap between the conveyor 112 and the conveyor 121.

  The belt conveyor 114 disposed in the gap includes, for example, three rotating bodies (rollers) for guiding the conveyance belt arranged in parallel in the horizontal direction in the drawing, and is connected to each other by a spring material 254 so that the belt conveyor 114 can expand and contract. .

  The belt conveyor 114 is held on both sides by the belt conveyor holding member 25. As a retracting structure of the belt conveyor 114, a rotating body (roller) is disposed below a rotating body (roller) that guides the conveyor belt, and the lower rotating body (roller) is moved downward as indicated by an arrow a. Thus, the interval between the upper rotating bodies is reduced and retracted. A mounting plate 253 having a rotating shaft 251 is provided at the lower portion of the belt conveyor holding member 25, a shaft of the lower rotating body is mounted at one end 252, and a piston rod 31 of the air cylinder 3 is mounted at the other end of the mounting plate 253. is there. The piston rod 31 is driven to pull or push. When the blocking wall is lowered, the piston rod 31 is retracted to give the mounting plate 253 a rotational motion, and the distance between the upper rotating bodies is reduced in the direction of the arrow b, so that the belt conveyor 114 is retracted.

In addition, a mechanism for moving the central rotating body (roller) downward among the three rotating bodies (rollers) is provided, and moved in the same manner as the lower rotating body (roller), so that the upper rotating body (roller) is moved. The interval may be narrowed.

Moreover, you may use together with a sliding slide mechanism similarly to the previous example.

  Further, as a retreat path for the belt conveyor 114, a retreat space can be formed by being controlled so as to close a used roller gap in a part of the conveyor 112.

  The detection mechanism for detecting the blocking operation of the blocking wall is the same as that shown in FIGS. 1 to 5, etc., and is not shown in FIG. When the blocking wall (not shown) is lowered, the detection mechanism detects the blocking operation, and the air cylinder 3 is driven to rotate the mounting plate 253 to retract the belt conveyor 114 from the gap. In this way, it is possible to prevent breakage of the blocking wall and the retracting conveyor accompanying the blocking operation of the blocking wall.

  In the illustrated example, as the retracting structure of the belt conveyor 114 provided in the gap, only one side of the conveyance path is shown, but it is provided on both sides and driven in synchronization. If dynamic operation and mechanical strength are taken into consideration, a retracting structure in which a drive device is provided only on one side may be used.

  FIG. 15A is a perspective view illustrating a blocking mechanism of a transport device according to a fourth embodiment of the present invention, illustrating a configuration before blocking the transport path, and FIG. 15B is a diagram after blocking the transport path. FIG.

  The conveyance path shown in FIG. 15A shows a configuration including belt conveyors 112, 113, and 121, similar to the conveyance path shown in FIG.

  In FIG. 15, the belt conveyor 113 disposed in the gap is rotatably attached as a retracting structure.

  In FIG. 15A, a transport path is formed by the belt conveyors 112 and 113 of the transport device 1 and the belt conveyor 121 of the transport device 12. The belt conveyor 113 disposed in the gap has a shaft of a rotating body (roller) 37 that gives rotation to the belt, and is attached to the holding member 25 so as to be rotatable.

  The tip of the piston rod 31 of the air cylinder 3 is attached to the shaft of the rotating body 36 of the belt conveyor 113.

  The mechanism for detecting the lowering of the blocking wall is the same as in FIG. 1 and is not shown. When the detection mechanism detects the lowering of the blocking wall, the piston rod 31 is retracted into the cylinder by supplying air from the air pipe 33 instead of supplying air from the air pipe 32 of the air cylinder 3. The belt conveyor 113 that has received this action rotates as shown in FIG. 15B with the axis of the rotating body (roller) 37 as the axis of rotation, and the belt conveyor 113 is retracted to form a gap A having a predetermined clearance. In this way, it is possible to prevent damage or the like associated with the lowering of the blocking wall. In this case, the rotation direction of the conveyor 113 performs the same function even in the direction opposite to the figure (upward), and also has the function of retaining the conveyed product flowing on the conveyor 1 side.

  In the illustrated example, as the retracting structure of the belt conveyor 113 provided in the gap, only one side of the conveyance path is shown, but it is provided on both sides and driven in synchronization. As in the previous embodiment, if a dynamic operation and mechanical strength are taken into consideration, a retracting structure in which a drive device is provided only on one side may be used.

  In each of the embodiments described with reference to FIGS. 12 to 15, the elastic member (spring member or the like) 30 as described with reference to FIG. 6 may be provided, and the tension member described with reference to FIG. 7. (Wire member etc.) 33 and weight 304 may be provided side by side.

  FIG. 16 is a perspective view for explaining a blocking mechanism of the transport apparatus according to the sixth embodiment of the present invention.

  FIG. 16 is different from FIG. 1 in that an emergency power source is used as an urging mechanism (retraction mechanism) for retreating the transport path and is operated with the power.

  In FIG. 16, the roller 13 which forms a conveyance path in the gap | interval between the conveying apparatus (conveyor) 11 and the conveying apparatus (conveyor) 12 is arrange | positioned in the place where the interruption | blocking equipment 5 is arrange | positioned. It is the same as in the previous embodiment that the blocking wall descending along the blocking wall guide rail 51 is detected in advance and the conveyance path (roller) 13 is retracted. In FIG. 16, the roller 13 is attached to the shaft 22 at one end of the rotating side plate 2. In addition, the other end side of the rotation side plate 2 is attached to a shaft 21 that can rotate on the side surface of the transport device 11. The rotating side plate 2 can be rotated by a rotating shaft 21. In addition, a driving device 340 that is driven by a power source is provided. A driving rod (bar) 310 that is driven to be pushed out or pulled in by the driving device 340 is provided, and one end 35 of the driving rod is attached to the lower side of the rotating side plate 2.

  The driving device 340 is normally driven by a normal power source and is provided with an emergency power source (which may be an emergency power source or the like) 300. While the regular power supply is being supplied, the emergency power supply 300 may be charged in parallel.

  Even if a power failure occurs due to a disaster such as a fire, the emergency power supply 300 can supply necessary power such as the drive device 340 and the detection mechanism 40.

  Accordingly, even when a power failure occurs in an emergency, the conveyance path can be retracted.

Moreover, you may control the drive device 340 by starting based on the notification information from alarm devices, such as a fire alarm and a smoke detector. The same applies to the embodiments described below.

The driving device 340 normally maintains the roller 13 as a transport path in a state where the driving rod (bar) 310 is pushed out by an ordinary power source.
On the other hand, a detection mechanism 40 that detects a blocking operation when a blocking wall (not shown) of the blocking facility 5 descends along the blocking wall guide rail 51 is provided. The detection mechanism 40 includes a detection unit 410 for blocking operation and a changeover switch 420 for notifying the drive device 340 of the detection result. A switching signal based on the detection result is transmitted to the driving device 340 via the signal line 430.
By this switching signal, the drive device 340 controls the drive rod (bar) 310 to be retracted by motor drive or the like, whereby the rotary side plate 2 rotates around the rotary shaft 21 as shown by the arrow a and serves as a conveyance path. The roller 13 is retracted.

Further, when detecting the cutoff operation by the detection mechanism 40 and, also operate to bias control to the retreat direction the transport path when at least one of the event occurred when switched to emergency power supply 300 during power outages it can.

  As described above, various configurations can be used as the detection unit of the detection mechanism that detects the movement of at least a part of the blocking wall or the wall surface. Further, even if the blocking wall has a function of detecting an obstacle with the movement of the blocking wall, it may be detected and moved with a pressing force less than the pressing force 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, the detection mechanism may be operated with a pressing force that does not activate the switch.

In addition, as a detection mechanism, a circuit that operates with an emergency power supply may be used even when a normal power supply cannot be used. Further, it may be detected without contact with the blocking wall. For example, a light detection mechanism, a sound wave detector, or a wireless device may be used. In the case of these non-contact detection mechanisms, transmission detection may be performed across the blocking range of the blocking wall, or reflection may be detected. Also, by placing the transceiver across a gap in the operating range of the blocking wall, or by determining the detection Tsu also be blocked transmission signal by interrupting the operation of the barrier walls.

  In the illustrated example, the retraction structure of the roller 13 provided in the gap is shown only on one side with respect to the conveyance path, but is provided on both sides and driven synchronously. If dynamic operation and mechanical strength are taken into consideration, a retracting structure in which a drive device is provided only on one side may be used. Further, the roller conveyor has been described as an example of the transport path, but the present invention is not limited to this roller conveyor, but may be applied to a belt conveyor configuration or other transport means, and may be applied to other embodiments. It is the same.

  FIG. 17 is a perspective view for explaining a blocking mechanism of the transport device according to the seventh embodiment of the present invention.

  17 is different from the configuration shown in FIG. 16 in that the retracting structure of the roller 13 disposed in the gap between the transport device 11 and the transport device 12 is slid to the transport device 11 side. The roller 13 is held on both sides by a roller holding member 25. A sliding member 23 is attached to the lower part of the roller holding member 25 and is coupled to a rail 24 provided on the conveying device side. A driving bar 310 is attached to the side surface of the roller holding member 24, and the driving bar 310 is connected to the driving device 340. The drive bar 310 is pulled or pushed out by a motor drive or the like provided in the drive device 340. When the roller holding member 25 is slid in the horizontal direction as indicated by the arrow a on the lower rail 24, the roller 13 is retracted when the blocking wall is lowered.

  Further, as a retreat path for the roller 13, a retreat space can be formed by controlling so as to close a part of the roller gap of the transport device 11.

  The blocking operation of the blocking wall, for example, the mechanism for detecting the lowering is the same as that shown in FIG. 16 and is not shown in FIG. 17, but when the blocking wall (not shown) is lowered in FIG. A drive instruction is issued to the described drive device 340 via a signal line. Accordingly, the driving device 340 retracts the roller 13 from the gap by pulling the driving bar 310 by motor driving or the like and slidingly driving the roller holding member 25. In this way, it is possible to prevent the blocking operation of the blocking wall, such as breakage due to the descent.

  Similarly to the one shown in FIG. 16, the drive unit 340 is supplied with power by an emergency power supply even when the normal service power is cut off, and thus functions effectively even if a power failure occurs during a disaster such as a fire.

  In the illustrated example, the retraction structure of the roller 13 provided in the gap is shown only on one side with respect to the conveyance path, but is provided on both sides and driven synchronously. If dynamic operation and mechanical strength are taken into consideration, a retracting structure in which a drive device is provided only on one side may be used.

  FIG. 18 is a perspective view for explaining a blocking mechanism of the transport apparatus according to the eighth embodiment of the present invention.

  18 is different from the configuration of FIG. 17 in that a belt conveyor is used for the conveyance path. As a conveyance path having a retraction mechanism, a belt conveyor 113 having a retraction structure is disposed in a gap between the conveyance device 11 and the conveyance device 12.

  The belt conveyor 113 disposed in the gap includes two or three rotating bodies that guide the conveyance belt arranged in parallel in the horizontal direction in the figure.

  The retracting structure of the belt conveyor 113 is slid to the conveying device 11 side as shown in FIG. The belt conveyor 113 is held by the belt conveyor holding member 25 on both sides. A sliding member 23 is attached to the lower portion of the belt conveyor holding member 25 and is coupled to a rail 24 provided on an attachment side (not shown) below the conveying device 11. A driving bar 310 is attached to the side surface of the belt conveyor holding member 25, and the driving bar 310 is connected to a driving device 340. The drive bar 310 is pulled or pushed out by a motor drive or the like provided in the drive device 340. The belt conveyor holding member 25 is slid laterally as indicated by the arrow a on the lower rail 24 and the belt conveyor 113 is retracted when the blocking wall is lowered.

  Further, the slider bed may be retracted in place of the central roller of the belt conveyor.

  Further, as the retreat path of the belt conveyor 113, a retreat space can be formed by controlling so as to close a part of the gap of the rollers used in the conveyor of the transport device 11.

  The mechanism for detecting the blocking wall, for example, the mechanism for detecting the lowering is the same as that shown in FIG. 16 and is not shown in FIG. 18, but when the blocking wall (not shown) is lowered, FIG. The detection mechanism detects the same as described above, and the driving device 340 retracts the belt conveyor 113 from the gap by pulling the driving bar 310 by motor driving or the like and slidingly driving the belt conveyor holding member 25. In this way, it is possible to prevent damage or the like accompanying the blocking operation of the blocking wall.

  Similarly to the one shown in FIG. 16, the drive unit 340 is supplied with power by an emergency power supply even when the normal service power is cut off, and thus functions effectively even if a power failure occurs during a disaster such as a fire.

  In the illustrated example, as the retracting structure of the belt conveyor 113 provided in the gap, only one side of the conveyance path is shown, but it is provided on both sides and driven in synchronization. If dynamic operation and mechanical strength are taken into consideration, a retracting structure in which a drive device is provided only on one side may be used.

  FIG. 19 is a perspective view for explaining a blocking mechanism of the transport apparatus according to the ninth embodiment of the present invention.

  In FIG. 19, the belt conveyor is used for a conveyance path like the structure shown in previous FIG. As a conveyance path having a retraction mechanism, a belt conveyor 114 having a retraction structure is disposed in a gap between the conveyance device 11 and the conveyance device 12.

  The belt conveyor 114 disposed in the gap includes, for example, three rotating bodies (rollers) for guiding the conveyance belt arranged in parallel in the horizontal direction in the drawing, and is connected to each other by a spring material 254 so that the belt conveyor 114 can expand and contract. .

  The belt conveyor 114 is held on both sides by the belt conveyor holding member 25. As a retracting structure of the belt conveyor 114, a rotating body (roller) is disposed below a rotating body (roller) that guides the conveyor belt, and the lower rotating body (roller) is moved downward as indicated by an arrow a. Thus, the interval between the upper rotating bodies is reduced and retracted. A mounting plate 253 having a rotating shaft 251 is provided at the lower portion of the belt conveyor holding member 25, a shaft of the lower rotating body is mounted at one end 252 thereof, and a drive bar 310 is mounted at the other end of the mounting plate 253. The drive bar 310 is connected to the drive device 340. The drive bar 310 is pulled or pushed out by a motor drive or the like provided in the drive device 340. When the blocking wall is lowered, the drive bar 310 is retracted to give the mounting plate 253 a rotational motion, thereby reducing the interval between the upper rotating bodies and retracting the belt conveyor 114.

In addition, a mechanism for moving the central rotating body (roller) downward among the three rotating bodies (rollers) is provided, and moved in the same manner as the lower rotating body (roller), so that the upper rotating body (roller) is moved. The interval may be narrowed . Moreover, you may use together with a sliding slide mechanism similarly to the previous example.

  Further, as a retreat path for the belt conveyor 114, a retreat space can be formed by being controlled so as to close a used roller gap in the conveyer 11 conveyor.

  The blocking operation of the blocking wall, for example, the mechanism for detecting the lowering is the same as that shown in FIG. 16 and is not shown in FIG. 19, but will be described with reference to FIG. 16 when the blocking wall (not shown) is lowered. The detection mechanism detects the same as described above, and the drive device 340 retracts the belt conveyor 114 from the gap by pulling the drive bar 310 by motor drive or the like and rotating the attachment plate 253. In this way, it is possible to prevent damage or the like accompanying the blocking operation of the blocking wall.

  Similarly to the one shown in FIG. 16, the drive unit 340 is supplied with power by an emergency power supply even when the normal service power is cut off, and thus functions effectively even if a power failure occurs during a disaster such as a fire.

  In the illustrated example, as the retracting structure of the belt conveyor 114 provided in the gap, only one side of the conveyance path is shown, but it is provided on both sides and driven in synchronization. If dynamic operation and mechanical strength are taken into consideration, a retracting structure in which a drive device is provided only on one side may be used.

  FIG. 20 is a perspective view for explaining a blocking mechanism of the transport device according to the tenth embodiment of the present invention.

  The conveyance path shown in FIG. 20 shows an example in which an object having a belt conveyor structure is used similarly to the conveyance path shown in FIG.

  In FIG. 20, the difference from the configuration of FIG. 18 is that the belt conveyor 113 is arranged in a gap between the transfer device 11 and the transfer device 12 as a transfer path having a retracting mechanism so as to be able to rotate and retract. is there.

  The belt conveyor 113 arranged in the gap corresponding to the shut-off facility is configured by arranging a plurality of rotating bodies that guide the conveyor belt in the horizontal direction in the figure.

  The retracting structure of the belt conveyor 113 is driven to rotate toward the conveying device 11 side. The belt conveyor 113 includes a belt conveyor holding member 25 that holds the shaft 37 of a roller member that controls the conveyor from both sides, and one end of a drive bar 310 that is connected to a driving device 340 that provides rotational driving. It is configured to be connected to a rotation axis 36 of a certain roller member.

  As a conveyance path arranged in a gap corresponding to the blocking facility 5, it is normally supported by the holding member 25 and one end of the drive bar 310 as shown in the illustrated example.

  When the belt conveyor 113 is withdrawn from the gap, the drive bar 310 is pulled by the drive device 340 and is connected to the front end side of the drive bar 310 with the axis 37 of the roller member held by the holding member 25 as the rotation axis. The roller member is rotated in the direction indicated by the downward arrow line a.

  Accordingly, the mechanism for detecting the lowering of the blocking wall when it is lowered as the blocking operation of the blocking wall (not shown) is the same as that shown in FIG. 16 and is not shown in FIG. The driving device 340 receives the detection result. As a result, the driving device 340 retracts the belt conveyor 113 from the gap by pulling the driving bar 310 by a motor drive or the like to rotate the belt conveyor 113. In this way, it is possible to prevent damage or the like associated with the lowering of the blocking wall.

  Similarly to the one shown in FIG. 16, the drive unit 340 is supplied with power by an emergency power supply even when the normal service power is cut off, and thus functions effectively even if a power failure occurs during a disaster such as a fire.

  In the illustrated example, as the retracting structure of the belt conveyor 113 provided in the gap, only one side of the conveyance path is shown, but it is provided on both sides and driven in synchronization. If dynamic operation and mechanical strength are taken into consideration, a retracting structure in which a drive device is provided only on one side may be used.

  FIG. 21 is a perspective view for explaining a blocking mechanism of the transport apparatus according to the eleventh embodiment of the present invention. FIG. 21 shows a case where a transport path having a retracting mechanism is formed between transport paths having steps with different heights.

FIG. 21 shows a case where the transport path of the transport apparatus 11 and the transport path of the transport apparatus 12 are stepped with respect to the floor surface, and a transport path (inclined plate) having an inclination between the transport apparatus 11 and the transport apparatus 12. ) 115 is connected. Even when the conveyance path 115 having a retreat function is formed corresponding to the shut-off equipment 5 during this period, drive control corresponding to an emergency of the conveyance apparatus 11, the conveyance apparatus 12, and the conveyance path 115 is performed.
In FIG. 21, an inclined conveyance path (inclined plate) 115 has a rotating shaft 1140 on the upper side of the inclined plate 115 and is attached to a support column 114 provided on the conveying device 11 side.

  The inclined plate 115 is driven to rotate downward, for example, as indicated by an arrow a, and is retracted so as not to prevent the blocking operation of the blocking wall of the blocking facility 5, for example, the lowering. Note that a detection mechanism, a driving device, and the like for the blocking operation can be the same as those shown in FIG.

  Here, as the direction of rotation retreat of the inclined plate 115, in addition to the arrow line a, as shown by the arrow line b, it may be revolved upward from the transport device 11. Further, as the rotation axis of the inclined plate 115, the lower end surface of the lower part may be fixed so as to become the rotation axis instead of the upper part. In this case, it is as the rotation of the inclined plate 115 or in the direction indicated by the arrow c.

  The configuration of the inclined plate 115 may be a single plate, but in the illustrated example, the plate member 115a made of a material having the first elasticity and the second plate member having a elasticity greater than the elasticity of the first plate member 115a. It may be constituted by a plate material 115b made of an elastic material. When the inclined plate 115 rotates and moves in the direction of the arrow a, the plate member 115b has greater elasticity, so that the tip side contacts the conveyance path (belt conveyor) 12 and moves downward against the conveyance path 12. Is also effective in preventing damage such as damage. The elastic plate material 115b may be a flame retardant material, a non-combustible material, or the like that can withstand abrasion or breakage, such as plastic, hard vinyl, or a plate rubber material. The plate material is not limited to these, and the plate material may be a plate-like shape, and the material is not limited to wood or steel. Further, the elastic plate material may be elastic, flexible and easily recoverable, and may be flexible or flexible. Further, by using this elastic plate member 115b, it is possible to prevent dropping or pinching when moving articles or the like to the subsequent conveying path (belt conveyor) 12, and in particular, conveying materials (end materials, broken materials including cardboard). , Waste materials, unnecessary materials, recycled materials, etc.).

  Although not shown in the figure, the drive unit is powered by the emergency power supply even if the normal utility power is cut off, as in the case shown in FIG. 16, so it is effective even if a power failure occurs during a disaster such as a fire. To work.

  The driving devices are provided on both sides of the conveyance path and are driven in synchronization. If dynamic operation and mechanical strength are taken into consideration, a retracting structure in which a drive control unit is provided only on one side may be adopted.

  FIG. 22 is a diagram for explaining the main configuration of the blocking mechanism of the transport apparatus according to the twelfth embodiment of the present invention.

  In FIG. 22, a spring 7 that biases the roller 13 in the gap in the gap direction is provided, and one end 72 of the spring 7 is slidably attached to the guide plate 73 and pulled by the springs 731 and 732. At the same time, it is fixed and maintained by a stop pin 74, and the other end is attached to the shaft 71 of the roller 13.

  On the other hand, the detection mechanism 4 that detects the lowering of the blocking wall includes a detection pin 41 as a detection unit that detects the lowering of the blocking wall, and a wire 76 is connected to the detection mechanism 4 instead of the air changeover switch. The wire 76 is connected to the stop pin 74 via the frame 75.

  When the blocking wall is lowered and the detection pin 41 detects the lowering of the blocking wall, the detection mechanism 4 rotates and pulls the wire 76. The stop pin 74 is pulled out by the tension generated in the wire 76, one end 72 of the spring 7 is pulled in the left direction in the figure by the springs 731 and 732, and the roller 13 is retracted from the gap in the left lateral direction. In this way, it is possible to prevent damage or the like associated with the lowering of the blocking wall.

  FIG. 23 is a diagram illustrating the configuration of the main part of the blocking mechanism of the transport device according to the thirteenth embodiment of the present invention.

  In FIG. 23, a spring 8 that biases the roller 13 in the gap in the gap direction is provided, and a weight 821 is attached to one end 82 of the spring 8 and attached to the guide plate 83 so as to be slidable in the vertical direction. The other end is fixed to the shaft 81 of the roller 13.

  On the other hand, the detection mechanism for detecting the lowering of the blocking wall is the same as that shown in FIG. 22 and is not shown, but the wire is connected to the stop pin 84 via the frames 85 and 86.

  When the blocking wall is lowered and detected, the detection mechanism rotates and pulls the wire. The roller 13 connected to the shaft 81 at the other end of the spring 8 is shown by the stop pin 84 being pulled out by the tension generated in the wire or rotating in the direction of the spring 8 and moving downward along the guide plate due to the weight of the weight 821. Pulled leftward, the roller 13 retreats from the gap. In this way, it is possible to prevent damage or the like associated with the lowering of the blocking wall.

  FIG. 24 is a side view for explaining the main configuration of the blocking mechanism of the transport device according to the fourteenth embodiment of the present invention.

  In FIG. 24, the conveying device 11 and the conveying device 12 are arranged with a predetermined gap with the interruption facility 5 as a boundary, and the roller 13 is arranged to be able to rotate and retract in the gap between the conveying devices. The conveyance path is formed by a roller conveyor 111 arranged on the conveyance device 11, a roller 13, and a roller conveyor arranged on the conveyance device 12.

  The roller retracting structure that accompanies the detection of the lowering of the blocking wall shown in FIG. 24 differs from FIG. 1 in that the roller is retracted by a mechanical operation without using an air supply / discharge mechanism.

  As a mechanism for detecting the lowering of the blocking wall 52, a wheel 92 is used as a rotating body that contacts the side surface of the blocking wall 52, and the wheel 92 and the idler 93 are fixed to both ends of the arm 91. The free wheel 93 side of the arm 91 is rotatably attached to the transport device 11 side and is pressed toward the wheel 92 by a pressing spring 96. A stopper 98 is provided so that the entire arm 91 does not move downward due to a force acting downward as the wheel 92 slides on the wall surface of the blocking wall 52.

  It can be said that the wheel 92, the arm 91, the idler 93, the pressing spring 96, etc. constitute a mechanism for detecting the lowering of the blocking wall 52.

  On the other hand, the roller 13 is attached to a rotatable fixing member 99, and a weight 97 having a predetermined weight is attached to the other end.

  Further, a wire 95 is attached around the idler 93 between the end portion 962 of the fixing member 99 to which the weight 97 is attached and the rotating shaft of the wheel 92.

  When the wheel 92 slides and rotates along the wall of the blocking wall 52 with the lowering of the blocking wall 52, the wire 95 is wound around the wheel shaft and the weight 97 is pulled up via the idler 93. Accordingly, the fixing member 99 is rotated, and the roller 13 is lowered and retracted.

Here, the winding force of the weight 97 and the wheel 92 is balanced with the pressing force of the pressing spring 96 against the blocking wall 52 of the wheel 92. According to the present invention, since the wall surface of the blocking wall is used, even if there is an automatic stop function based on obstacle detection on the lower surface of the blocking wall as the blocking wall is lowered, it is not affected.

  That is, the fixing member 99 rotates in accordance with the upward movement of the weight 97, and the roller 13 is moved and retracted from the gap to a predetermined position. In this way, it is possible to prevent damage or the like accompanying the lowering of the blocking wall.

In addition, although it is the structure which enabled automatic return | restoration and return | restoration by the vertical movement of the weight 97, a weight is unnecessary by using a timing belt instead of a wire, and the reciprocating operation of the timing belt by rotation of the wheel 92 is also possible. It becomes possible to return.
Although not shown in the figure, the opposite side surface is similarly configured to detect the lowering of the blocking wall 52 and retract the roller, and is driven from both ends of the roller 13. In addition, when it is possible to physically control only one side due to the relationship between the members of the conveyance path and the strength, it is not necessary to provide the same configuration at both ends.

  FIG. 25 is a view for explaining a blocking mechanism of the transport device according to the fifteenth embodiment of the present invention.

  In FIG. 25, the same reference numerals used in FIG. 24 indicate the same object, and the point of great difference from the previous embodiment is that the lateral pressure spring of the arm 91 that supports the rotating body 92 that detects the lowering of the blocking wall 52. Instead of 96, a spring (spring) 963 for pulling the support arm (support member) 91 is provided in the central portion of the support arm 91.

  During normal use in which the blocking wall 52 does not operate, the arm 91 is urged downward by a pulling spring (spring) 963 so that the wheel 92 is in a predetermined position on the blocking facility 5 side. When there is a blocking operation of the blocking wall 52, the wheel 92 comes into contact with the wall surface of the blocking wall 52 along with this lowering, and the rotation of the wheel 92 is detected to detect the lowering of the blocking wall 52. The pulling spring (spring) 963 maintains the wheel 92 as the descent detecting means, and also maintains the conveying path retracting operation due to the rotation operation of the wheel 92 accompanying the lowering of the blocking wall.

Although the example of using a spring (spring) to maintain the retracting action of the transport path, without being limited thereto, corresponding to the to move during the the saving operation to maintain the conveying path in a normal state A spring material can be used.

When the wheel 92 has a weight and is lowered by its own weight to maintain the equilibrium, a spring member such as a spring (spring) 963 may be unnecessary.
Although not shown, the opposite side surface is similarly configured to detect the lowering of the blocking wall 52 and retract the roller, and is driven from both ends of the roller 13. In addition, when it is possible to physically control only one side due to the relationship between the members of the conveyance path and the strength, it is not necessary to provide the same configuration at both ends.

  FIG. 26 is a side view illustrating the main configuration of the blocking mechanism of the transport device according to the sixteenth embodiment of the present invention.

  In FIG. 26, the detection of the lowering of the blocking wall 52 and the retraction of the roller 13 are performed using an inverted U-shaped member 101 in the illustrated example, with the tip of the upper side serving as the detection unit of the rotating body or the protrusion 53 and the other end of the upper side rotated. The shaft 103 is rotatably attached to the member attaching portion 102. This upper side becomes the drive bar of the member 101. In addition, a shaft 105 of the roller 13 is attached to the tip of the lower side of the member 101, and a pressing spring 106 is attached to the opposite end 104. In the normal state in which the blocking wall 52 is housed, the U-shaped member 101 maintains the roller 13 in a predetermined position by the pressing force of the pressing spring 106, and the roller conveyor of the transport device 11, the roller 13, and the roller conveyor of the transport device 12 are used. A conveyance path is formed. In this case, the lowering force of the blocking wall is larger than that of the pressing spring 106.

  Further, the normal position of the roller 13 can be maintained by providing a spring that pulls in the middle of the rotating shaft 103 and the end 104 in the direction opposite to the direction of the arrow c instead of the pressing spring 106. Moreover, it can replace with these springs and can be pulled with a weight.

  When the blocking wall 52 descends, the rotating body or projection 53 disposed on the side surface of the blocking wall 52 rotates the upper side downward about the rotation shaft 103 of the U-shaped member 101. Along with this, the lower side also rotates against the spring 106 and the roller 13 is retracted from the gap as indicated by the dotted line in the figure.

  In this way, the roller 13 can be moved and retracted from the gap to a predetermined position, and damage due to the lowering of the blocking wall can be prevented.

  Although not shown, the opposite side surface has the same configuration and is driven from both ends of the roller 13. In addition, when it is possible to physically control only one side due to the relationship between the members of the conveyance path and the strength, it is not necessary to provide the same configuration at both ends. Further, the illustrated inverted U-shaped member constituted by the upper side, the lower side, and the side connecting the upper side and the lower side may be made by integral molding. Further, the rotation shaft 103 may be provided in the middle between the position of the mounting portion 102 shown in the figure and the protruding end on the blocking wall side. In addition, the upper limit of the rotation of the member 101 may be provided by providing a stopper for restricting the member 101, or the rotation shaft may be restricted.
