In addition, a plurality of sheets may be stacked and transported. Therefore, it is considered to send out in a vertical posture so as not to apply weight, but when the horizontal posture is set in the subsequent process, it is necessary to change from the vertical posture to the horizontal posture during the transportation.
As a transport device for switching the transport posture of the transported object, for example, an aligned transport device for square objects as described in Patent Document 1 is known. The square object is composed of a large number of square sheets bundled together, and has a first alignment conveyor in which two belt conveyors are arranged in a V shape, and a loading conveyor that loads the square object into the first alignment conveyor. It is configured to include a receiving conveyor for receiving the square objects discharged from the first alignment conveyor.
In the first conveyor for alignment, the lower surface of the square of the square is in contact with one belt conveyor, the side surface in the thickness direction is in contact with the other belt conveyor, and one side corresponding to the corner of the lower surface of the square and the side surface of the rectangle is V-shaped. It is transported in a constant tilted posture along the valley of. In that state, it falls on the transport surface of the receiving conveyor, and is aligned horizontally on the transport surface of the receiving conveyor, with one side of the corner between the lower surface and the side surface as a fulcrum, and the lower surface is in contact with the transport surface. It has become like.

The inclined conveyor 32 is composed of an endless belt hung between a pair of rollers 33, 34 arranged at the upstream end and the downstream end of the conveying direction X, and the rollers 33, 34 convey the inclined conveyor 32. It is rotatably supported by the first side frame 36a and the second side frame 36b located at the ends orthogonal to the transport direction with respect to the direction, and one of the rollers 33 and 34 is driven by a motor and the other. The rollers are configured to drive and rotate.
The transport surface of the inclined conveyor 32 is horizontal with respect to the transport direction, and is an inclined transport surface 32a that is inclined in one direction with respect to the horizontal in the direction orthogonal to the transport direction. It is arranged along the lower side edge of 32. Due to the inclined structure of the inclined transport surface 32a, the falling pouch P is tilted with the reference side A as a fulcrum and the upper side is tilted to the opposite side to the reference guide 35, and the fallen pouch P is slid toward the reference guide 35. It has become.

Fall to the side. The fallen pouch P is configured to slide the pouch P to the side where the height of the inclined transport surface 32a is low due to the component force of gravity.
The inclination angle θ of the inclined conveyor surface 32a of the inclined conveyor 32 is preferably in the range of about 10 ° to 60 °.
As shown in FIG. 2A, the arrangement relationship between the inclined transport unit 30 and the vertical feed unit 10 is such that in the rolling station 20, the reference side A at the lower end of the pouch P that abuts against the abutting member 22 and falls is the inclined conveyor. It is a region between both side edges of 32, and is arranged at a position offset to the first side frame 36a side so as to fall in the vicinity of the lower side edge 32a1. Then, the distance in the direction orthogonal to the transport direction from the drop position of the reference side A of the pouch P to the side edge 32a2 on the higher side of the inclined conveyor 32 is set to be larger than the width of the maximum size pouch P. There is. As shown in FIG. 1, the second side frame 36b may be provided with a side guide 36c that guides the upper side of the fallen pouch P.
Further, the distance between the upstream end of the inclined conveyor 32 in the transport direction and the abutting member 22 is larger than the length of the maximum size pouch P in the transport direction, and the downstream end of the inclined conveyor 32 in the transport direction is the abutting member. A sufficient distance is set from 22 until the reference side A of the pouch P that has fallen on the inclined conveyor surface 32a comes into contact with the reference guide 35.

Further, in the middle of the transport direction of the inclined conveyor 32, a vibrating roller 37 that vibrates the inclined conveyor 32 up and down to promote the movement of the pouch P that has fallen on the inclined conveyor 32 toward the reference guide 35 is arranged.

The vibrating roller 37 is provided at the same position in the transport direction as the guide roller 38 arranged at the intermediate position in the transport direction of the rollers 33 and 34. A reference guide 35 is arranged in the guide roller 38, and a vibrating roller 37 is arranged on a high side opposite to the reference guide 35.
The vibrating roller 37 has a configuration in which a plurality of protrusions 37a are provided on the outer peripheral surface, and the protrusions 37a intermittently lift the inclined conveyor 32 to vibrate the inclined conveyor 32 up and down at a predetermined cycle. As a result, the frictional force with the pouch P mounted on the inclined conveyor 32 is reduced, the movement to the lower side due to the component force of gravity is promoted, and the movement to the reference guide 35 side is facilitated.

(Timing station)
On the downstream side of the inclined conveyor 32 of the inclined conveyance unit 30, a timing station 50 in which a timing roller pair 52 for sending out the pouch P and a timing stopper 54 are arranged is provided.
A guide roller 55 that presses the pouch P from above is provided at the downstream end of the inclined conveyor 32 in front of the timing station 50 to prevent the pouch P from rising.
As shown in FIG. 4, the timing roller pair 52 has a plurality of roller main bodies 52b intermittently arranged in the axial direction on the roller shaft 52a which is parallel to the inclined conveyance surface 32a of the inclined conveyor 32 and extends in the direction orthogonal to the conveying direction. In this example, the timing stoppers 54 are provided at three locations, and the timing stoppers 54 are arranged at two locations between the roller main body 52b of the timing roller vs. 52.
By arranging them in two places, the minimum size is temporarily stopped by the timing stopper 54 on the side of the reference guide 35, and the timing is taken, and the minimum size is sent out by the two timing roller pairs 52. On the other hand, the maximum size pouch P is paused by two timing stoppers 54, timed, and sent out by the timing roller pair 52.
On the further downstream side of the timing roller pair 52, a feed roller 56 is provided as a feed roller for feeding the pouch P to the horizontal transport unit 40 on the further downstream side.
The timing stopper 54 is L-shaped and includes a stopper piece 54a extending between the timing roller pair 52 via a bent portion and an operating piece 54b extending upward. For example, the operating piece 54b is held so as to always be in the stopped position in the transport stopped state (see FIG. 4B), and the stopper piece 54a is retracted from the transport path by the pouch discharge request signal in the transport instruction state. It may be configured to switch to the evacuation position (see FIG. 4 (A)).
The presence or absence of the pouch P is detected in the region between the downstream end of the inclined conveyor 32 and the abutting member 22 in the plan view of the first side frame 36a on the reference guide 35 side of the inclined conveyor unit 30. A pouch sensor 58 is arranged to detect the pouch P, and after a lapse of a predetermined time, a pouch discharge request signal is output.

(Horizontal transport unit 40)
The horizontal transfer unit 40 is arranged on the downstream side of the inclined transfer unit 30, and includes a horizontal conveyor 42 having a horizontal transfer surface 42a that is horizontal to the transfer direction and also horizontal to the direction orthogonal to the transfer direction. .. ing. The transport direction of the pouch P is arranged parallel to the transport direction of the tilted transport unit 30, and the two sides parallel to the transport direction in the plan view substantially coincide with the two side sides parallel to the transport direction of the tilted transport unit. On one side, a reference guide 45 extending on an extension of the reference guide 35 of the inclined conveyance unit 30 is provided.
The horizontal conveyor 42 is hung on a pair of rollers 43, 44 arranged at the upstream end and the downstream end in the transport direction. The rollers 43 and 44 are rotatably supported by a pair of side frames 46a and 46b arranged to the left and right with respect to the transport direction of the horizontal transport unit, one roller is driven by a motor, and the other roller is driven to rotate. It is configured to do.
The horizontal transport surface 42a of the horizontal conveyor 42 has the same height as the side edge 32a1 on the reference guide 35 side of the inclined conveyor 32, and the side edge 42a1 on the reference guide 45 side is the side edge of the reference guide 35 of the inclined conveyor 32. Located on an extension of 32a1, the other side edge 42a2 is lower than the other side edge 32a2 of the inclined conveyor 32.

Next, the operation of the transfer device for the sheet-shaped conveyed object will be described.
In this example, on the upstream side of the vertical feed unit 10, a pouch feeding section (not shown) that feeds the pouches P in a vertical posture one by one is arranged, and the pouches P sent from the pouch feeding section are vertically fed one by one. It is fed to the unit 10 and is transported along an arc-shaped transport path W1 composed of a plurality of transport roller pairs 12 of the vertical feed unit 10, and is fed from the most downstream transport roller pair 121 to the abutting member 22 of the rolling station 20. It is discharged toward.
The pouch P separated from the most downstream transfer roller pair 121 of the vertical feed unit 10 protrudes forward due to inertia, the tip of the pouch P abuts against the abutting member 22 and stalls, and the inclined conveyor 32 of the downward inclined conveyor unit 30 due to its own weight. It falls on the inclined conveyor surface 32a and the lower reference side A comes into contact with the inclined conveyor surface 32a. Due to the inclination of the inclined transport surface 32a, the upper side with the reference side A as a fulcrum falls to the side opposite to the reference guide 35, that is, the side having a higher height, and the reference side A of the pouch comes into contact with the reference guide 35 in parallel.
The position where the reference side A of the pouch falls may be the side edge 32a1 of the reference guide 35, and in this case, the side edge 32a1 is preferably inclined at an inclination angle of the inclined conveyance surface 32 or more.

In the present embodiment, the transport roller pair 12 of the pouch P is short of the transport roller pair 121 on the most downstream side, and the upper portion not sandwiched by the transport roller pair 121 is in a free state. On the other hand, the lower edge of the pouch that has passed through the most downstream transport roller pair 121 is engaged with the guide groove 14a of the runway 14 and the discharge direction is directed in the direction parallel to the transport direction of the inclined transport unit 30, but it is restrained. The upper side, which is not provided, tilts freely toward the front side (tilted transport unit 30 side) following the curvature of the transport path W1, and is discharged while tilting forward. Finally, when the rear end passes through the conveyor pair 121 on the most downstream side and is no longer restrained, it hits the abutting member 22 while falling forward, whereby the stalled pouch P falls forward and moves downward. It is designed to assist the operation of falling on the inclined conveyor 32 and falling on the inclined conveyor 32.
In the case of the small size pouch P1, the rear end of the pouch P0 passes through the runway 14 and then comes into contact with the abutting member 22 and falls downward as it is, but in the case of the large size pouch P0, the transport roller pair 121 on the outlet side The rear end of the pouch P0 that has left the pouch P0 is engaged with the runway 14 to prevent the rear end side of the reference side A from slipping forward, and the upper end side of the pouch P0 is oriented so as to surely fall forward. ing.
As described above, in the present embodiment, the curved shape of the transport path W1, the regulation of the pouch P from falling to the back side by the guide roller 16 and the support member 24, and the guide groove 14a of the runway 14 change the posture of the pouch (fall). Construct a means of assistance to assist.
Of course, even if there is no guide groove 14a, the reference side A slides down to the lower side of the inclined conveyor surface due to the inclined structure of the inclined conveyor 32a, so that the assisting means is only the support member 24. But it may be.
The pouch P that has fallen on the inclined transport surface 32a is transported while sliding toward the reference guide 35 by the component force of gravity in the direction orthogonal to the transport direction of the inclined transport surface 32a and toward the reference guide 35, and is transported while sliding toward the reference guide 35. A abuts on the reference guide 35, is guided in the transport direction along the reference guide 35, abuts on the timing stopper 54 located in front of the nip portion of the timing roller pair 52 of the timing station 50, and stops (FIG. 4 (FIG. 4). See A)). At the position in front of the timing station 50, the upper surface of the pouch P is pressed by the guide roller 55 to prevent the pouch P from floating from the inclined conveyor 32. Further, the standby state of the pouch P is detected by the pouch sensor 58, and when the transport start signal is input, the timing stopper 54 moves from the stop position to the retracted position (see FIG. 4B), and the pouch P moves. It is sent out to the horizontal transport unit 40 on the downstream side by the timing roller pair 52 and the feed roller pair 56.
If the timing stopper 54 is provided in this way, the tip of the pouch P whose side position is positioned by the reference guide 35 can be sent out at a predetermined timing regardless of the size of the pouch P.
The pouch delivered by the timing roller pair 52 is delivered onto the horizontal conveyor 42 of the horizontal transfer unit 40 by the feed roller 56 arranged downstream. Since the feed roller 56 nips the feed roller 56 and feeds the feed to the horizontal transport unit 40, the feed roller P can be fed to the horizontal transport surface 42a without shifting the reference side A of the pouch P.

(Other configuration examples of assistive means)
FIG. 5 shows an example in which the rolling station 20 is provided with the rolling lever 25 as an assisting means for assisting the falling operation of the pouch on the inclined conveyor 32. It should be noted that, in FIG. 5B, the reference side A is used as a fulcrum and it is described so that it falls down on the spot, but in reality, it falls downward while falling down, and it is a diagram for explaining the direction of falling down.
The rolling lever 25 has an L-shape in a plan view, and is a fulcrum 2 provided at a bent portion.
It includes an operation piece 252 that is swingably supported in the transport direction about 51 and extends from the bent portion on the movement locus of the pouch P, and an extruded piece 253 that extends from the bent portion to the upstream side in the transport direction.
The extruded piece 253 is provided with a protrusion 254 so as to swing between a retracted position that does not interfere with the back surface of the pouch P and an extruded position that pushes the pouch P forward from the back surface side from the retracted position. It has become.
Then, when the pouch P is discharged, the operation piece 252 is pushed and rotated by the tip of the pouch P, and the extrusion piece 253 is swung from the retracted position to the extrusion position by the rotation of the operation piece 252 to extrude the pouch P. It is configured to assist the movement of falling in the direction.

In the above embodiment, a so-called self-supporting pouch having a gusset portion at the bottom has been described as an example of the sheet-shaped transported object, but it can also be applied to transporting a pouch such as a flat pouch having no gusset portion. Further, regardless of the pouch, it can be widely applied to the transportation of sheet-shaped conveyed materials such as single-wafer sheets, single-wafer films, and various plate-shaped materials.
