Effect of the Invention

[0014] When a roller conveyor is used to transport an object in a forward direction, the object is transported in the forward direction when all of the rollers are rotated in the forward direction. When the roller conveyor is used to transport an object in the reverse direction, the object is transported in the reverse direction by rotating all the rollers in the opposite direction to the forward direction. When a roller conveyor conveys an object in one width direction of the roller conveyor, adjacent rollers are rotated so that they rotate in opposite directions. When the roller conveyor is used to transport the object in the other width direction, the adjacent rollers are rotated in opposite directions from when the object is transported in one width direction.

[0015] The adjacent rollers are arranged in a roller conveyor in such a manner that the adjacent rollers are sequentially arranged symmetrically with respect to the boundary between the adjacent rollers in the forward direction and the reverse direction to the forward direction, with the oblique conveying direction being mutually inclined. Therefore, when adjacent rollers are rotated in the opposite direction, the object to be transported placed on the roller conveyor is transported to the common roller conveyor width side at the tip end side of the inclination direction of the rollers attached to the adjacent rollers. The object is transported to the end of the roller conveyor that is attached to adjacent rollers and has a common inclined end. When the rotation direction of each of the adjacent rollers is made opposite to that of the previous roller, the transported object placed on the roller conveyor is transported to the opposite side of the width of the roller conveyor from the previous one.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Reference numeral 11 denotes a roller conveyor. Reference numeral 51 denotes legs of the roller conveyor 11, and reference numeral 52 denotes casters. The roller conveyor 11 is folded and stored between the front and rear legs. The roller conveyor 11 will now be outlined. Reference numeral 21 denotes rollers constituting the roller conveyor 11. The roller conveyor 11 has a plurality of rollers 21 arranged in sequence in a forward direction F, which is a direction in which an object to be conveyed (not shown) is conveyed. The roller conveyor 11 can rotate in a direction in which an object to be conveyed placed on the roller conveyor 11 is conveyed in the forward direction F, or in a direction opposite to the forward direction F. The roller conveyor 11 has roller shafts 22, which are the rotation axes of the unit roller unit assemblies 31, aligned in the conveying direction, and rotates the unit roller unit assemblies 31 in conjunction with the rotation of the roller conveyor 11 to convey the placed object to be conveyed.

[0018] Rollers 21 transport an object placed on transport surface M, which is an imaginary plane on rollers 21 connecting the upper ends of rollers 21 that contact the object. The surface obtained by connecting the contact points with the object, which are the upper end faces of rollers 21, becomes transport surface M. In plan view, this is transport surface M. 1 to 3, G is a forward end, and H is a reverse end. The conveying surface M of the roller conveyor 11 is set horizontally. The conveying surface M contacts the conveyed object at the upper ends of the rollers 21 and applies a driving force to the conveyed object.

[0019] The roller 21 has a plurality of roller units 41, which are smaller than the roller 21, inclined on the surface. The rollers 21 obtain a conveying direction for the conveyed object that is oblique to the forward direction F depending on the setting direction of the unit roller unit 41 relative to the rollers 21. The roller 21 is made up of a roller 21(B) and a roller 21(C) that are unit roller units 41 with different inclination directions. One of the rollers, 21(B), has a diagonal transport direction at 45 degrees to the right with respect to the forward direction F in a planar transport plane M. The other roller, 21(C), has a diagonal transport direction at 45 degrees to the left with respect to the forward direction F in a planar transport plane M. The rollers 21(B) and 21(C) are alternately arranged in the forward direction F. Adjacent rollers 21 are sequentially arranged in line symmetry with respect to a boundary J between adjacent rollers 21 in the forward direction F and the opposite direction to the forward direction F, which are oblique to each other.

[0020] Roller 211, roller 213, roller 215, roller 217, roller 219, and roller 221 shown in Figs. 1 and 2 are one roller 21(B). Rollers 212, 214, 216, 218, 220 and 222 shown in Figs. 1 and 2 are the other rollers 21(C). Adjacent roller shafts 22 are arranged parallel to each other.

[0021] Reference numeral 22 denotes a roller shaft. The roller shaft 22 is a rotation axis of the roller 21. All the roller shafts 22 are installed perpendicular to the forward direction F. The motors 23 (231 to 241) have the same capacity and the driving forces are the same. The motor 231 is attached to and drives the roller 211. The motor 232 is attached to and drives the roller 212. Thereafter, the motors 23 are attached to the roller shafts 21 in order. A motor 233 is attached to the roller 213 and drives it. A motor 234 is attached to the roller 214 and drives it.

[0022] A motor 235 is attached to roller 215 and drives it. A motor 236 is attached to roller 216 and drives it. A motor 237 is attached to roller 217 and drives it. A motor 238 is attached to roller 218 and drives it. A motor 239 is attached to the roller 219 and drives it. A motor 240 is attached to the roller 220 and drives it. A motor 241 is attached to the roller 221 and drives it. A motor 242 is attached to the roller 222 and drives it.

[0023] Motor 23 (231 to 241) is controlled by the control unit to rotate all rollers 211 to 222 in the forward direction F (rotating so as to transport the loaded object in the forward direction F), rotate all of them in the direction opposite to the forward direction F, rotate every other roller in the forward direction F and the direction opposite to the forward direction F, or rotate every other roller in the forward direction F, the reverse direction and the forward direction F.

[0024] Reference numeral 31 denotes a unit roller unit assembly. Reference numeral 32 denotes a rotation shaft hole of the unit roller unit assembly 31. The rotation shaft of the unit roller unit assembly 31 is the roller shaft 22, which is the rotation shaft of the unit roller unit assembly 31. The unit roller unit assembly 31 rotates as a roller 21 with the roller shaft 22, which is the rotation shaft of the unit roller unit assembly 31, passing through the rotation shaft holes 32 of the multiple unit roller unit assemblies 31 as the axis.

[0025] Reference numeral 41 denotes a unit roller unit. Reference numeral 42 denotes a unit roller unit rotation shaft. The unit roller unit rotation shaft 42 is the rotation shaft of the unit roller unit 41. The unit roller unit 41 rotates as a roller by itself with the unit roller unit rotation shaft 42 as its axis. Roller 21 has a plurality of unit roller unit assemblies 31 attached to its surface, and is made up of a plurality of unit roller unit assemblies 31. Unit roller unit assemblies 31 are made up of a plurality of unit roller units 41.

[0026] The unit roller unit 41 will be further described. The roller unit 41 is smaller than the roller 21, and a plurality of roller units 41 are attached to the surface of the roller 21 as shown in FIG. 8 and other figures in this embodiment, and can rotate on a roller unit rotation shaft 42. All of the roller unit rotating shafts 42 transmit a conveying force to the conveyed object in contact with the roller unit 41 as the roller shafts 22 rotate by the motors 23 of the same capacity. The unit roller unit rotation shafts 42 are all attached at the same angle for each roller 21 to the roller shaft 22 which is the rotation shaft of the unit roller unit assembly 31. The unit roller unit rotation shafts 42 are attached at an angle of 45 degrees to the roller shaft 22 which is the rotation shaft of the unit roller unit assembly 31.

[0027] In this embodiment of the invention, the oblique conveying direction is set at the same angle of 45 degrees for each roller 21 with respect to the forward direction F. The mounting angle of the unit roller unit 41 with respect to the roller 21 determines the oblique conveying direction of the conveyed object. As shown in FIG. 2, in the unit roller unit 41 attached to one roller 21 (B), the unit roller unit rotation shaft 42 is inclined 45 degrees to the left in the conveying direction oblique to the reverse direction to the forward direction F. Therefore, as shown in FIG. 2, in the unit roller unit 41 attached to one roller 21 (B), the conveying direction oblique to the reverse direction to the forward direction F is inclined 45 degrees to the right.

[0028] As shown in Figs. 2 and 4, in the unit roller unit 41 attached to the other roller 21(C), the unit roller unit rotation shaft 42 is inclined 45 degrees to the right in the oblique conveying direction relative to the reverse direction to the forward direction F. Therefore, as shown in Figs. 2 and 4, in the unit roller unit 41 attached to the other roller 21(C), the conveying direction oblique to the reverse direction to the forward direction F is inclined 45 degrees to the left.

[0029] Since the unit roller units 41 are inclined with respect to the rollers 21, the tips of the rotation shafts of the unit roller units 41 face the same width direction, L1 or L2, of the roller conveyor 11. The tip direction and inclination direction of the unit roller unit rotation shafts 42, which are the rotation shafts of the attached multiple unit roller units 41, also face the same width direction, one width direction L1 or the other width direction L2. Therefore, the respective conveying directions are the same direction.

[0030] The tip of the rotation shaft of the unit roller unit 41 attached to the roller shaft 22, which is the rotation shaft of the adjacent unit roller unit aggregate 31, faces the same width direction of the roller conveyor 11, that is, one width direction L1 or the other width direction L2. Therefore, the respective conveying directions are the same. The inclination directions of the unit roller units 41 attached to the roller shafts 22, which are the rotation shafts of the adjacent unit roller unit assemblies 31, are opposite to each other, and the unit roller units 41 attached to the adjacent roller shafts 22 face each other or face away from each other.

[0031] The roller unit assembly 31 will now be described in further detail. As shown in the figure, the unit roller unit assembly 31 is attached with a plurality of unit roller units 41 (nine in this embodiment) attached along the outer periphery so that the roller surfaces of the unit roller units 41 are exposed to the outside and form a transport surface M for transporting the object. The unit roller unit assembly 31 is cylindrical as a whole as shown in Figures 4 to 11, and has a rotation shaft hole 32 for the unit roller unit assembly 31 provided in the center. The roller shaft 22, which is the rotation shaft of the unit roller unit assembly 31, passes through the rotation shaft hole 32 of the unit roller unit assembly 31, and a plurality of unit roller unit assemblies 31, six unit roller unit assemblies 31 in this embodiment, are passed through and fixed.

[0032] Reference numeral 32 denotes a rotation shaft hole of the roller unit assembly 31 . The rotation shaft of the unit roller unit aggregate 31 is the rotation shaft of the unit roller unit aggregate 31 . In this embodiment, the rotation shaft of the unit roller unit assembly 31 is made up of a roller shaft 22 which is the rotation shaft of the roller 21. The roller shaft 22 penetrates through a rotation shaft hole 32 of the unit roller unit assembly 31.

[0033] The unit roller unit assembly 31 is generally cylindrical as shown in Figures 4 to 11. One of both end faces of the cylindrical unit roller unit assembly 31 is one end face 33, and the other is the other end face . The unit roller unit rotating shaft 42 on which the unit roller unit 41 is attached has its tip attached near the outer periphery of one cylindrical end face 33 and its other end attached near the outer periphery of the other cylindrical end face 34 . Both mounting ends of unit roller unit rotation shaft 42 are inclined (25 degrees to 60 degrees) rather than parallel to roller shaft 22 to which unit roller unit aggregate 31 is attached, and are attached near both end faces of unit roller unit aggregate 31. In this embodiment, unit roller unit aggregate 31 is attached at an angle of 45 degrees rather than parallel to roller shaft 22, which is the rotation shaft of unit roller unit aggregate 31 to which unit roller unit aggregate 31 is attached. The angle may also be 30 degrees.

[0034] In this embodiment of the present invention, the unit roller unit 41 is attached at an angle of 45 degrees to the rotation direction of the roller shaft 22 (the rotation shaft of the unit roller unit aggregate 31), which is the rotation shaft of the roller 21. As shown in the figure, by tilting the unit roller unit 41 45 degrees to the right with respect to the roller shaft 22, the oblique conveying direction of the roller 21 and the unit roller unit 41 becomes 45 degrees to the right. The left end of unit roller unit 41 faces diagonally 45 degrees to the left in the forward direction. By tilting the unit roller unit 41 45 degrees to the left with respect to the roller shaft 22, the oblique conveying direction of the roller 21 and the unit roller unit 41 becomes 45 degrees to the left. The right end of the unit roller unit 41 faces diagonally 45 degrees to the right in the forward direction.

[0035] The adjacent rollers 21 are arranged diagonally to the right and diagonally to the left with respect to the forward direction F, so that the conveying directions are opposite to each other. 2, the adjacent rollers 21 are sequentially installed so that the oblique transport directions are symmetrical with respect to the boundary J between the adjacent rollers 21 in the forward direction F and the opposite direction to the forward direction F. The oblique transport directions in the forward direction F and the opposite direction to the forward direction F are installed so as to be line-symmetrical with respect to the boundary J between the adjacent rollers 21.

[0036] In other words, the inclination direction of the unit roller units 41 attached to the rotation shafts of adjacent unit roller unit assemblies 31 is such that the roller shafts 22 of adjacent unit roller unit assemblies 31 are mutually obliquely arranged in a linear symmetrical manner with respect to the boundary J between the unit roller unit assemblies 31 that are adjacent rollers 21 in the forward direction F and the opposite direction to the forward direction F.

[0037] Adjacent rollers 21 are sequentially installed in line symmetry with respect to a boundary J between adjacent rollers 21 in the oblique transport directions in the forward direction F and the reverse direction relative to the forward direction F. Roller 21 (B) has a diagonal transport direction oriented 45 degrees to the right relative to the reverse direction relative to the forward direction F. Roller 21 (C) has a diagonal transport direction oriented 45 degrees to the left relative to the reverse direction relative to the forward direction F. Adjacent rollers 21 installed on the roller conveyor 11 are arranged symmetrically with respect to a boundary J. One roller 21 (B) is inclined 45 degrees to the left with respect to the forward direction F, and the other roller 21 (C) is inclined 45 degrees to the left with respect to the forward direction F. The inclination direction may be reversed between one roller 21 (B) and the other roller 21 (C). One roller 21(B) may be inclined 30 degrees to the right with respect to the forward direction F, and the other roller 21(C) may be inclined 30 degrees to the left with respect to the forward direction F. The roller shaft 22, which is the rotation shaft of the unit roller unit assemblies 31 of the adjacent rollers 21 installed on the roller conveyor 11, is installed in parallel with the roller shaft 22.

[0038] The unit roller unit rotation shaft 42 is attached so as to be inclined in the opposite direction to the roller shaft 22 which is the rotation shaft of the unit roller unit aggregate 31 and to the roller shaft 22 which is the rotation shaft of the adjacent unit roller unit aggregate 31 . Therefore, when the roller shaft 22, which is the rotation shaft of the adjacent unit roller unit assemblies 31, is rotated in reverse by the motor 23, the transported object is transported to the common width side of the roller conveyor 11, which is the tip side in the inclined direction of the unit roller unit rotation shaft 42, which is respectively attached to the roller shaft 22, which is the rotation shaft of the adjacent unit roller unit assemblies 31. The transported object is transported left and right, which is the width direction, in a forward direction F, which is the direction in which the object is transported by the rollers 21.

[0039] When the roller shafts 22, which are the rotation shafts of two adjacent roller unit assemblies 31, rotate in the forward direction F of the conveying directions of the roller conveyor 11, the conveyed object is conveyed in the forward direction F. Although the unit roller units 41 rotate in an oblique direction, a component force in a lateral direction relative to the forward and reverse transport directions of the roller conveyor 11 is offset by the mutually opposite oblique rotation of adjacent unit roller units 41. When the roller shafts 22, which are the rotation shafts of two adjacent roller unit assemblies 31, rotate in the opposite direction of the conveying direction of the roller conveyor 11, the articles are conveyed in the opposite direction. Although the unit roller units 41 rotate in an oblique direction, a component force in a lateral direction relative to the forward and reverse transport directions of the roller conveyor 11 is offset by the mutually opposite oblique rotation of adjacent unit roller units 41.

[0040] In an embodiment of the present invention, the objects to be conveyed can be conveyed not only in the forward direction F and in the direction opposite to the forward direction F, but also in the directions of 3 o'clock and 9 o'clock when the direction of travel of a conventional conveyor (forward direction F) is taken as 12 o'clock. When the roller conveyor 11 is to transport an object in a forward direction F, the roller shafts 22, which are the rotation shafts of all the roller unit assemblies 31, are rotated in the same direction, that is, the forward direction F, by the motor 23, thereby transporting the object in the forward direction F. When the roller conveyor 11 conveys the object in the direction opposite to the forward direction F, all the rollers 21 are rotated in the direction opposite to the forward direction F by the motor 23. When roller shafts 22, which are the rotation shafts of all roller unit assemblies 31, are rotated by motor 23 in the direction opposite to forward direction F, the transported object is transported in the reverse direction.

[0041] When the roller conveyor 11 is to convey an object in one width direction L1 of the roller conveyor 11, the roller shafts 22 which are the rotation shafts of the adjacent rollers 21, i.e., the roller unit assemblies 31, are rotated by the motors 23 so as to rotate in opposite directions.

[0042] That is, roller 211 rotates in the opposite direction to the forward direction F (rotates so as to transport the loaded object in the opposite direction to the forward direction F), and roller 212 adjacent to roller 211 rotates in the forward direction F (rotates so as to transport the loaded object in the forward direction F). Roller 213 is rotated in the opposite direction to the forward direction F, and roller 214 adjacent to roller 213 is rotated in the forward direction F. Roller 215 rotates in the opposite direction to the forward direction F, and roller 216 adjacent to roller 215 rotates in the forward direction F. Roller 217 rotates in the opposite direction to the forward direction F, and roller 218 adjacent to roller 217 rotates in the forward direction F. Roller 219 rotates in the opposite direction to the forward direction F, and roller 220 adjacent to roller 219 rotates in the forward direction F. The roller 221 is rotated in the opposite direction to the forward direction F, and the roller 222 adjacent to the roller 221 is rotated in the forward direction F.

[0043] Roller 211 rotates in the opposite direction to the forward direction F (rotating so as to transport the loaded object in the opposite direction to the forward direction F), and roller 212 adjacent to roller 211 rotates in the forward direction F (rotating so as to transport the loaded object in the forward direction F). The roller 211 and the roller 212 adjacent to the roller 211 are in a state of inward rotation, so to speak. The rotational forces in the forward and reverse transport directions of the roller conveyors 11 of the adjacent collective shafts are cancelled out, and the object is transported to the L1 side, which is combined by the inclination direction of the adjacent roller 211 and the unit roller unit 41 attached to the roller 211. The same is true for roller 213 and roller 214 adjacent to roller 213. The same is true for roller 215 and roller 216 adjacent to roller 215. The same is true for roller 217 and roller 218 adjacent to roller 217. The same is true for roller 219 and roller 220 adjacent to roller 219. The same is true for roller 221 and roller 222 adjacent to roller 221.

[0044] Roller 212 rotates in a forward direction F (rotating so as to transport the loaded object in the forward direction F), and roller 213 adjacent to roller 212 rotates in the opposite direction to the forward direction F (rotating so as to transport the loaded object in the opposite direction to the forward direction F). Roller 212 and roller 213 adjacent to roller 212 are in a state of abduction, so to speak. The rotational forces of the roller conveyors 11 in the forward and reverse conveying directions of the adjacent collective shafts are diffused. The same is true for roller 214 and roller 215 adjacent to roller 214 . The same is true for roller 216 and roller 217 adjacent to roller 216. The same is true for roller 218 and roller 219 adjacent to roller 218 . The same is true for roller 220 and roller 221 adjacent to roller 220.

[0045] When the roller conveyor 11 transports the object in the other width direction L2, the adjacent rollers 21, i.e., the roller shafts 22 which are the rotation shafts of the unit roller unit assemblies 31, are rotated in the opposite direction by the motor 23 from when the object is transported in one width direction L1. When the roller conveyor 11 conveys an object in one width direction L1 of the roller conveyor 11, the roller shafts 22 which are the rotation shafts of the adjacent roller unit assemblies 31 are rotated by the motors 23 so as to rotate in opposite directions. When the roller conveyor 11 transports the object in the other width direction L2, the roller shafts 22, which are the rotation shafts of adjacent roller unit assemblies 31, are rotated in the opposite direction by the motor 23 from when the object is transported in one width direction L1.

[0046] When the roller conveyor 11 conveys the object in one width direction L1 of the roller conveyor 11, the roller shafts 22, which are the rotation shafts of the adjacent roller unit assemblies 31, are rotated by the motors 23 so as to rotate in the opposite directions. When the roller conveyor 11 transports the object in the other width direction L2 of the roller conveyor 11, the adjacent rollers 21, i.e., the roller shafts 22 which are the rotation shafts of the unit roller unit assemblies 31, are rotated in the opposite direction by the motor 23 from when the object is transported in one width direction L1.

[0047] That is, roller 211 rotates in a forward direction F (rotates so as to transport the loaded object in the forward direction F), and roller 212 adjacent to roller 211 rotates in the opposite direction to the forward direction F (rotates so as to transport the loaded object in the opposite direction to the forward direction F). The roller 213 is rotated in a forward direction F, and the roller 214 adjacent to the roller 213 is rotated in a direction opposite to the forward direction F. Roller 215 rotates in a forward direction F, and roller 216 adjacent to roller 215 rotates in a direction opposite to the forward direction F. Roller 217 rotates in a forward direction F, and roller 218 adjacent to roller 217 rotates in a direction opposite to the forward direction F. Roller 219 rotates in a forward direction F, and roller 220 adjacent to roller 219 rotates in a direction opposite to the forward direction F. The roller 221 is rotated in a forward direction F, and the roller 222 adjacent to the roller 221 is rotated in a direction opposite to the forward direction F.

[0048] That is, roller 211 rotates in a forward direction F (rotating so as to transport the loaded object in the forward direction F), and roller 212 adjacent to roller 211 rotates in the opposite direction to the forward direction F (rotating so as to transport the loaded object in the opposite direction to the forward direction F). The roller 211 and the roller 212 adjacent to the roller 211 are in a state of abduction, so to speak. The rotational forces of the roller conveyors 11 in the forward and reverse conveying directions of the adjacent collective shafts are diffused. The same is true for roller 213 and roller 214 adjacent to roller 213. The same is true for roller 215 and roller 216 adjacent to roller 215. The same is true for roller 217 and roller 218 adjacent to roller 217. The same is true for roller 219 and roller 220 adjacent to roller 219.

[0049] Roller 211 rotates in a forward direction F (rotating so as to transport the loaded object in the forward direction F), roller 212 adjacent to roller 211 rotates in the opposite direction to the forward direction F (rotating so as to transport the loaded object in the opposite direction to the forward direction F), and roller 213 rotates in the forward direction F. The roller 211 and the roller 212 adjacent to the roller 211 are in a state of abduction, so to speak. The rotational forces in the forward and reverse transport directions of the roller conveyors 11 of the adjacent collective shafts are cancelled out, and the object is transported to the L1 side, which is combined by the inclination direction of the adjacent roller 211 and the unit roller unit 41 attached to the roller 211. The same is true for roller 213 and roller 214 adjacent to roller 213. The same is true for roller 215 and roller 216 adjacent to roller 215. The same is true for roller 217 and roller 218 adjacent to roller 217. The same is true for roller 219 and roller 220 adjacent to roller 219. The same is true for roller 221 and roller 222 adjacent to roller 221.

[0050] When the roller shaft 22, which is the rotation shaft of the adjacent unit roller unit assemblies 31, is rotated in reverse by the motor 23, the transported object placed on the roller conveyor 11 is transported to the common width side of the roller conveyor 11 on the inclined tip direction side of the unit roller unit rotation shafts 42, which are respectively attached to the roller shafts 22, which are the rotation shafts of the adjacent unit roller unit assemblies 31.

[0051] When the roller conveyor 11 is to transport an object in the forward direction, the object is transported in the forward direction when all the rollers 21 are rotated in the forward direction. When the roller conveyor 11 is to convey the object in the reverse direction, the object is conveyed in the reverse direction by rotating all the rollers 21 in the direction opposite to the forward direction. When the roller conveyor 11 is used to convey an object in one width direction of the roller conveyor 11, the adjacent rollers 21 are rotated so as to rotate in opposite directions. When the roller conveyor 11 is used to transport the object in the other width direction, the adjacent rollers 21 are rotated in the opposite directions from when the object is transported in one width direction.

[0052] Adjacent rollers 21 are roller conveyors 11 which are sequentially installed symmetrically with respect to a boundary J between adjacent rollers 21 in the forward and reverse directions relative to the forward direction, so that the oblique conveying directions are mutually inclined. Therefore, when adjacent rollers 21 are rotated in the opposite direction, the object to be transported placed on the roller conveyor 11 is transported to the common width side of the roller conveyor 11 at the tip end side of the inclined direction of the rollers 21 attached to the adjacent rollers 21, respectively. The rollers 21 are attached to adjacent rollers 21, and the objects to be conveyed are conveyed to the end side of the roller conveyor 11 on the common end side of the inclined ends of the rollers 21. When the rotation direction of the adjacent rollers 21 is made opposite to that of the previous roller, the transported object placed on the roller conveyor 11 is transported to the width side of the roller conveyor 11 opposite to the previous one.
