Next, a description will be given of the operation when a drive signal is transmitted from the control device 31 to drive the attitude changing roller 30 to rotate, and the transfer conveying section 5 is changed from the conveying attitude to the retracted attitude.

When a drive signal is transmitted from the control device 31 to the motor of the posture changing roller 30 , the rotating shaft portion 33 rotates and the main body tubular portion 32 rotates relative to the rotating shaft portion 33 . Then, as shown in FIG. 10(a), the transfer conveying section 5 connected to the main tube portion 32 also rotates around the main tube portion 32 in the circumferential direction and assumes a retracted posture. That is, the transfer conveying section 5 rotates toward the side where the transfer roller 50 separates from the other conveying device 200 as the main tube section 32 rotates.
At this time, in the present embodiment, the movable range of the regulating portions 52a and 52b is restricted by the connecting member 13a, and the connecting members are arranged so as not to exceed the over-retraction posture even if the transfer transport unit 5 rotates beyond the retraction posture. It is locked at 13a.
Specifically, in the excessive retraction posture, the connecting member 13a passes outside the small-diameter wall portions 71 of the restricting portions 52a and 52b and comes into contact with one locking wall portion 73, as shown in FIG. 10(b). Posture change is regulated so that the handover conveying unit 5 does not exceed the over-conveyance posture. That is, the restricting portions 52a and 52b are stopped by the connecting member 13a and are at the bottom dead center, and the rotation is physically restricted. As a result, it does not rotate beyond the over-retraction posture, and eventually becomes the retraction posture shown in FIG. 10(a) due to its own weight or the like.

Next, the positional relationship of each member in the retracted posture of the conveying device 1 of this embodiment will be described.

As shown in FIGS. 2 and 4, the transfer transport section 5 is accommodated in the storage space 8 of the main transport section 2, and the passage space 6 between the main transport section 2 and another transport device 200 is open. ing. Therefore, the fire shutter 201 can enter the passage space 6 as shown in FIG.
The transport side frames 10a and 10b are connected by main transport rollers 11a to 11d and connecting members 13a and 13b.
As shown in FIG. 4, the fixed plate portions 55a and 55b are respectively fixed to intermediate portions of the posture changing rollers 30 between the transport side frames 10a and 10b.
The interval between the support plate portions 56a and 56b is wider than the interval between the fixed plate portions 55a and 55b, and supports the rotary shaft portions 63 and 63 forming both ends of the transfer roller 50. As shown in FIG.
The base end of the wiring member 65 of the transfer roller 50 is covered with a protective cover 53 as shown in FIG. That is, the connecting portion (see FIG. 8) of the wiring member 65 to the rotary shaft portion 63 is protected by the protective cover 53 .

Next, the positional relationship of each member in the over-retraction posture of the transport device 1 of the present embodiment will be described.

As shown in FIG. 10B, the transfer roller 50 is rotated from the conveying posture beyond the retracted posture, and is further away from the passage space 6 than in the conveying posture.
The roller support portions 51a and 51b are slightly inclined with respect to the perpendicular line L passing through the centers of the fixing holes 70 of the restricting portions 52a and 52b.
The inclination angle θ of the roller support portions 51a and 51b with respect to the perpendicular line L shown in FIG. 12(a) is preferably 10 degrees or more and 30 degrees or less. Within this range, it is easy to grasp the posture by visual observation, and it is less likely to be an obstacle in terms of space.
The lowest point of the transfer roller 50 in the excessive retraction posture is higher by a height H than the lowest point of the transfer roller 50 in the retraction posture of the retraction posture or the hanging posture.

Subsequently, a drive signal is sent from the control device 31 to drive the posture changing roller 30 to rotate in the direction opposite to that when changing to the retracted posture, thereby causing the transfer conveying section 5 to move to the retracted posture or hang down. The operation when changing from the posture to the transport posture will be described.

When a drive signal is transmitted from the control device 31 to the motor of the posture changing roller 30 , the rotating shaft portion 33 rotates and the main body tubular portion 32 rotates relative to the rotating shaft portion 33 . Then, as shown in FIG. 11(a), the transfer conveying section 5 connected to the main tubular portion 32 also rotates in the circumferential direction around the main tubular portion 32 and assumes the conveying posture. In other words, the transfer roller 50 of the transfer conveying unit 5 moves toward the other conveying device 200 as the main tubular portion 32 rotates.
At this time, as shown in FIG. 11(a), the connecting member 13a passes outside the small-diameter wall portions 71 of the restricting portions 52a and 52b and comes into contact with the locking wall portion 74 on the other side. That is, the restricting portions 52a and 52b are locked by the connecting member 13a to reach the top dead center, and the rotation is physically restricted. As a result, even if the control device 31 always energizes the posture changing rollers 30 and drives the posture changing rollers 30 to rotate, the transfer conveying unit 5 does not rotate and the conveying posture is maintained.
In this embodiment, the Hall signal of the brushless motor of the posture changing roller 30 is detected by the control device 31, and when the transfer conveying unit 5 reaches the conveying posture, it is stopped by the connecting member 13a and the Hall signal of the brushless motor is detected. no change in When there is no change in the Hall signal of the brushless motor, the control device 31 determines that the sheet is in the conveying attitude, and reduces the output to the brushless motor to set the holding state. Therefore, it is possible to suppress the power consumption in the transport posture.

Next, the positional relationship of each member in the transport posture of the transport device 1 of this embodiment will be described.

As shown in FIG. 11( a ), the transfer conveying section 5 is positioned between the main conveying section 2 and another conveying device 200 so as to close the passage space 6 .

The term "substantially the same height" as used herein means substantially the same height, and specifically means that the height difference is 3 mm or less.
In this embodiment, the top of the transfer roller 50 is lower than the tops of the main transport rollers 11a to 11d of the main transport section 2 by about 1 mm.

Next, a description will be given of the operation when the orientation changing roller 30 is deenergized due to a power failure or the like, and the conveying orientation or the retraction orientation is changed to the hanging orientation.

When the orientation changing roller 30 is deenergized, the orientation changing roller 30 has a built-in brushless motor, so that a short brake is applied to the orientation changing roller 30, and the conveying orientation is slowly changed to the hanging orientation. be.
At this time, as shown in FIG. 11(b), the transfer conveying unit 5 hangs down from the attitude changing roller 30 due to its own weight, and the transfer roller 50 is the lowest point.

According to the conveying device 1 of the present embodiment, the connecting member 13a that connects the conveying-side frames 10a and 10b that support the main conveying rollers 11a to 11d allows the transfer conveying section 5 to change its posture beyond the conveying posture. to lock. That is, since the transport posture is physically maintained, it is safe, the number of parts can be reduced compared to the conventional art, and the cost can be reduced.
Further, according to the conveying apparatus 1 of the present embodiment, when changing from the conveying posture to the retracted posture and when changing from the retracted posture to the conveying posture, the connecting member 13a moves relative to the restricting portions 52a and 52b. , and engages with the locking walls 73 and 74 to maintain the conveying posture. Therefore, the structure can be simplified further.
