Abstract:
Switchboard transport system in particular for a gravity roller table which is switchable between a straight out position and a deflection position for deflecting of transport goods from a main conveyor to a lateral conveyor branching from the main conveyor, comprising a group of roller bodies with horizontally running rotation axes, wherein the roller bodies (40, 140) are disposed rotatable around their rotation axes at in each case a fork (30, 130) and wherein each fork (30, 130) exhibits a bearing bolt (36) disposed vertical downwardly projecting from the fork (30, 130), which bearing bolt (36) is introduced from the top into a vertically disposed, on the top open bearing bush (24, 24a, 124) of a bearing block (20, 120) not participating in the swivel motion, such that the fork (30, 130) is swivelable supported between a first position and a second position around the vertical swivel axis in the bearing block (20, 120), wherein the switch (3) is disposed in the straight out position in case the forks (30, 130) are disposed in each case in the first position and wherein the switch (3) is disposed in the deflection position, in case the forks (30, 130) are disposed in each case in the second position, wherein the forks (30, 130) are lifted such by the lift mechanism during the swiveling from the first position into the second position such that the transport goods (10) are at least partially lifted relative to the transport system by at least one of the roller bodies (40, 140) upon passage of the switch (3) characterized in thateither the fork (30) exhibits a head plate (35) exhibiting recesses (72) at its lower side (11) and is disposed in the end region of the bearing bolt (36) and wherein the wall of the bearing bush (24) is limited on its top by an upper front face (25) exhibiting projections (76), wherein the bearing bolt (36) is introduced from the top into the bearing bush (24) for a swivelable support of the fork (30) around a vertical axis and wherein the lower side (11) rests on the upper front face (25), wherein the projections (76) and the recesses (72) are disposed such that the projections (76) engage into the recesses (72) in the first position of the fork (30) and do not engage in the second position of the fork (30) into the recesses (72) such that the fork (30) is disposed in the second position in a lifted position relative to its position in the first position by the depth of the recesses (72) or the height of the projections (76), or the fork (30) exhibits a head plate (35) disposed in the upper end region of the bearing bolt (36), wherein the lower side (12) of the head plate (35a) is plane and inclined relative to a horizontal, and wherein the wall of the bearing bush (24a) is limited on the top by a plane upper front face (26) inclined relative to a horizontal, wherein the bearing bolt (36) is introduced from the top into the bearing bush (24) for a swivelable support of the fork (30) around the vertical axis and wherein the lower side (12) rests on the upper front face (26), wherein the spatial position of the lower side (12) and of the upper front face (26) are oriented such relative to each other that the fork (30) is disposed in the second position in a lifted position relative to its position in the first position, or the bearing block (120) exhibits recesses (82) and the fork (130) exhibits a rotary plate (131) with projections (86), wherein the rotary plate (131) rests on the upper front face of the bearing bush (124) and wherein the projections (86) engage into the recesses (82) in the first position of the fork (130) and wherein the projections (86) in the second position of the fork (130) rest on the bearing block (120) outside of the recesses (82) such that the fork (130) is disposed in the second position in a lifted position relative to the position in the first position by the depth of the recesses (82) or by the height of the projections (86).
