The lifting / lowering cylinder device (for example, an air cylinder is used) 22 and a transfer frame (transfer support body) 23 provided at a predetermined height by the lifting / lowering cylinder device 22 so as to freely move up and down. Yes.

  As shown in FIGS. 2, 3, and 5, the transfer frame 23 is erected on a horizontal support plate 24 connected to the lifting cylinder device 22 and on the horizontal support plate 24 at predetermined intervals. A plurality of mounting plates (for example, five locations) 25 (which are rising portions and, of course, are provided at positions corresponding to each other between the conveying rollers 13 and 13), and a plurality of mounting plates 25 respectively. A rotating ring body (for example, a belt pulley is used) 26 that is rotatably provided around an axis orthogonal to the conveying roller 13 is wound endlessly around each rotating ring body 26. And a transfer belt (in an example of an endless belt, specifically, a rubber belt having a round cross section) for transferring the article in contact with the bottom surface of the article W; To rotate a predetermined rotating ring body 26 And a rotary driving device 28..

  Here, the rotating wheel body 26 will be described. A plurality of supporting rotating wheel bodies 31, a driving rotating wheel body 32 for driving a transfer belt, and a tension for tensioning the transfer belt 27. The rotating ring body 33, the pressing rotating ring body 34 for pulling the transfer belt 27 inward and pressing it against the supporting rotating ring body 31 side, and the transfer belt 27 coming out of the tension rotating ring body 33 It is comprised from the rotation wheel body 35 for a guide for guiding up upwards.

  The rotary drive device 28 for rotating the drive rotary wheel body 32 is disposed on the support plate member 24 and the motor 37 having the rotary drive wheel body 36 attached to the output shaft and the mounting plates 25. The driving belt 40 wound endlessly across the rotating driven wheel 39 attached to one end of the connecting shaft 38 for connecting the driving rotating wheels 32 to each other and the rotating driving wheel 36. It consists of and. That is, when the driving belt 40 is driven by the electric motor 37, the driving rotating wheel body 32 is rotated via the rotating driven wheel body 39 and the connecting shaft body 38 on one end side, and all (for example, five) are transferred. The belt 27 is driven. Therefore, the article W supported (placed) on the upper surface thereof is moved to the lower-side transport conveyor 4 side and transferred.

The mounting positions of these rotating wheel bodies 26 (31 to 35) will be described.
For example, six (first to sixth) support rotating wheels 31 are sequentially arranged on the upper edge of each mounting plate 25 in the transfer direction b orthogonal to the transport direction.

  The driving rotating wheel body 32 and the tension rotating wheel body 33 are arranged closer to the lower conveying conveyor 4 from the center in the width direction of the upper conveying conveyor 2, specifically, the driving rotating wheel body 32. Is arranged immediately below the fifth supporting rotating wheel body 31E and the sixth supporting rotating wheel body 31F, and the tension rotating wheel body 33 is located below the fifth supporting rotating wheel body 31D in more detail. Is disposed immediately below the driving rotary body 32 and on the upper side (in the transfer direction) in the transfer direction.

The guide rotating wheel 35 is disposed near the center of the mounting plate 25, that is, at a position immediately below between the third supporting rotating wheel 31C and the fourth supporting rotating wheel 31D.
The driving direction (movement direction) of the tension rotating wheel body 33 is a direction between the driving rotating wheel body 32 and the guide rotating wheel body 35, specifically, closer to the lower-side conveyor 4. For example, in a direction from the lower side of the mounting plate 25 toward the upper center of the mounting plate 25, for example, on a substantially bisector of the central angle connecting the centers of the driving rotating wheel 32, the tension rotating wheel 33 and the guiding rotating wheel 35. Therefore, each mounting plate 25 is formed with a guide groove 25a that can guide the bearing portion 38a of the tension rotating wheel 33 in the direction thereof, and each mounting plate 25 has the bearing portion 38a below. A tensioning device (not shown) such as a weight is provided for pulling.

  In this way, the attachment portion of the attachment plate 25 on which the tension rotating wheel body 33 is movably provided has a triangular shape (also referred to as a trapezoid) that protrudes downward at a position closer to the lower-side conveyance conveyor 4. Since the guide rotating wheel 35 for guiding the transfer belt 27 is also arranged at the center and above the mounting plate 25, at least a portion on the opposite side of the lower conveyor belt 4 from the mounting plate 25 and for guiding. Since the lower part of the rotating ring body 35 is made an empty space (lower space part) and the lifting cylinder device 22 for raising and lowering the transfer frame 23 is arranged in this empty space, for example, the entire transfer frame 23 is The overall height of the main body frame (conveyor frame including the transfer device) in the transport facility is made lower than that in which the lifting and lowering cylinder device 22 is arranged so as to be supported from the bottom surface. It is possible.

  Further, the tensioning direction for tensioning the tension rotating wheel 33 is between the driving rotating wheel 32 and the guide rotating wheel 35 disposed on both sides of the tension rotating wheel 33. Therefore, even if the tension rotating wheel 33 is moved during the tension (adjustment), it can be made to coincide with the tension direction of the tension rotating wheel 33 by the transfer belt 27. Since the winding angle of the transfer belt 27 with respect to the tension rotary body 33 does not change so much, the driving force is not changed.

  Further, on the upper transport conveyor 2 side in the transport facility 1, a stopper device 41 for positioning the transported article W at a predetermined position above the transfer device 3 and the lower transport conveyor 2 from the lower transport conveyor 2. A guide roller device 42 used for transferring the article W onto the side conveyor 4 is provided, and the stopper W 41 is operated by detecting the article W conveyed on the upper conveyor 2. A stock detection sensor (for example, a photo sensor) 43 is provided.

  The stopper device 41 includes a cylinder device 44 attached to the front lower connecting frame 11A connected between the front bottom surfaces of the left and right side frames 12, and the front and rear transport rollers 13 at a predetermined position by the cylinder device 44. , 13 is formed of a flat plate-like stopper portion 45 that can be moved up and down above the conveying surface c.

  Further, the guide roller device 42 is bolted to each end on the lower-side transport conveyor 4 side of the front and rear lower connection frames 11A and 11B connected between the front bottom surfaces and the rear bottom surfaces of the left and right side frames 12. 46 and a double nut 47, respectively, and a guide roller 49 (also referred to as a feed roller) supported at both ends by the support brackets 48. The bolt 46 is fixed to the lower surface of the support bracket 48 in the vertical direction.

  In the above configuration, when the article W to be transferred to the lower transport conveyor 4 is transported by the upper transport conveyor 2, the stopper device 41 is actuated by the detection signal from the stock detection sensor 43, and the stopper section As the 45 is raised, the conveyed article W is stopped at that position and positioned.

  When the positioning is performed, the cylinder device 44 is actuated to raise the transfer frame 23, and the article W is transferred via the transfer belt 27 wound around the support rotary ring 31 provided on each mounting plate 25. Is lifted above the conveying surface c.

  When the article W is lifted, each driving rotary wheel 32 is rotated by the electric motor 37, and the article W is transferred to the lower conveyance conveyor 4 side by the transfer belt 27 via the guide roller 49. .

  As described above, the drive rotary wheel 32 and the guide rotary wheel 35 disposed below the support rotary wheel 31 are shifted to either one of the width directions of the transfer conveyor 2, for example, the lower transfer conveyor 4. Ascending / descending to move the transfer frame 23 of the transfer device 3 in the space below the guide rotating wheel 35 and the guide rotating wheel 35 disposed on the other side. Since the lifting cylinder device 22 is arranged, that is, the lifting cylinder device 22 is juxtaposed to the side of the tension rotating wheel 33, for example, the entire bottom surface of the transfer frame 23 is supported by the lifting cylinder device. Compared with the configuration, the overall height of the main body frame in the transport conveyor 2 can be reduced, and therefore the transport equipment can be made compact.

  Further, the tensioning direction (movement direction) of the tension rotating wheel body 33 is set to be between the driving rotating wheel body 32 and the guide rotating wheel body 35 disposed on both sides of the tension rotating wheel body 33. Therefore, the moving direction can be made to coincide with the pulling direction by the transfer belt 27, and therefore the winding angle of the transfer belt 27 changes so much even when the tension rotating wheel 33 is moved during tension. Therefore, there is no change in driving force.

  The stopper device 41 is connected to the left and right side frames 12 and 12 and is attached to the front and rear lower connection frames 11 which are firmly connected to each other by the support plate 21. Compared with the case where it is attached not to the connecting frame 11 but to a support frame provided separately in the width direction of the conveyor 2, the number of components can be reduced, and the number of manufacturing steps can also be reduced. .

  Further, with respect to the guide roller device 42, the support bracket 48 is attached to the end portions of the front and rear lower connecting frames 11 via bolts 46 and double nuts 47 fixed to the support bracket 48 side. For example, the height of the guide roller 49 can be adjusted very easily as compared with a structure in which the support bracket 48 is formed on the side frame 12 using a mounting plate parallel to the side surface. More specifically, holes (both at least one of which is a vertically long hole) are formed on both sides of the side frame or the mounting plate, and bolts are inserted into both holes and tightened with nuts to fix the support bracket. In the case of mounting on the side frame, it is necessary to loosen the nut when adjusting the height of the guide roller. In this case, the mounting plate, that is, the guide roller is held and the height is adjusted. On the other hand, in the case where the bolt is fixed directly to the lower surface of the mounting plate and attached with a double nut, the height is adjusted only by rotating the nut without holding the guide roller side. Can do.
