Wherein, chassis T ... do not have under the situation of adaptor union, set the actuating device 5 that formerly transports in the downstream of carrying line L1, L2 for the actuating device smaller than the transportation speed of chassis actuating device 2, perhaps, if set brake equipment 4 for, then can with compress this chassis T ... the state of ranks, with certain conveyance speed conveyance continuously.
Below, the conveyer 1 to first embodiment of the invention is described, be the explanation that example is carried out with second carrying line.As shown in Figure 1, catch up with the friction-roller type actuating device 3 of usefulness, the chassis Tcu that catches up with that is used to make the rear end chassis Tre from the second carrying line L2 to separate in updrift side catches up with rear end chassis Tre, as shown in Figure 3 and Figure 4, contact conveyance to catch up with chassis Tcu by the friction roller 17 that rotation is driven with drive surface 10.
In addition, as shown in Figure 3 and Figure 4, the friction-roller type actuating device 3 that catches up with usefulness can be by 11,11 supports of linear guidance device as guiding device, and move along the conveyance direction A of chassis T, by the application of force as the cylinder 12 of force application apparatus and downstream.
Promptly, about the guide rail 11a of linear guidance device 11,11,11a is fixed on the permanent seat 8, carriage 11b, 11b are fixed on the mobile foundation 9, therefore, mobile foundation 9 and the friction-roller type actuating device 3 on this mobile foundation 9 can be with respect to permanent seats 8 and are moved along the conveyance direction A of chassis T.In addition, rotatably support the cylinder main body 12a of cylinder 12 around the left and right directions axle with respect to permanent seat 8, with respect to mobile foundation 9 around the left and right directions axle front end of support piston bar 12b rotatably, therefore, according to the air fed air pressure of cylinder 12, friction-roller type actuating device 3 downstream (arrow A among the figure) of catching up with usefulness are the application of force flexibly.
In addition, with regard to this force application apparatus, it is not limited to cylinder, because by acting on the power of the aftermentioned upstream direction on the friction-roller type actuating device 3 that catches up with usefulness, this actuating device 3 can be resisted the application of force of force application apparatus, and upstream direction (arrow B among the figure) moves, and therefore, also can use for example compression coil spring.
In addition, can support the cylinder main body 21a that separates the cylinder 21 of actuating device as butt joint rotatably around vertical axis F by the carriage up and down 19,19 that is arranged on the stay bearing plate 18 on the mobile foundation 9 and be fixed on this stay bearing plate 18, wherein, described butt joint separates actuating device makes friction roller 17 to the direction of separating with respect to the drive surface 10 of catching up with chassis Tcu, and perhaps Dui Jie direction moves.The leading section of the piston rod 21b of cylinder 21, the leading section 15b with arm 15 rotatably connects around vertical axis.
Therefore, if drive cylinder 21, make piston rod 21b flexible, then because arm 15 rotates around vertical axis C, so can make actuating device 16 that is supported on this arm 15 and the friction roller 17 that drives by these actuating device 16 rotations moves to the direction of direction of separating with respect to the drive surface 10 of catching up with chassis Tcu or butt joint (with reference to the arrow ST of Fig. 3, in addition, arm 15 to the state that catches up with the direction rotation that chassis Tcu separates with reference to the long and two-short dash line among Fig. 3).Wherein, limit switch 32a, 32b are used for the expanding-contracting action of control plunger bar 21b, and detect the position (end of travel) of this piston rod 21b.
Like this, make friction roller 17 separate actuating device owing to have to the butt joint that the direction of direction of separating with respect to the drive surface 10 of catching up with chassis Tcu or butt joint moves, therefore, even the width for chassis is bigger, the leading section of drive surface 10 is the chassis in bight, and friction roller 17 is worked to this drive surface 10 smoothly.
Promptly, at first, drive the cylinder 21 that separates actuating device as butt joint, piston rod 21b is shunk, each at the state that friction roller 17 and the drive surface 10 of catching up with chassis Tcu are separated, by the sensors such as limit switch that do not illustrate among the figure detect catch up with chassis Tcu by the state of conveyance to the friction-roller type actuating device 3 that catches up with usefulness after, drive cylinder 21, so that piston rod 21b stretches out, thereby, the drive surface 10 that can make friction roller 17 contacts catch up with chassis Tcu.In addition, by adjusting the supply gas pressure of cylinder 21, and can be easily the pressure of the friction roller 17 of contact drive surface 10 be adjusted.
Below, to passing through chassis actuating device 2, with the second carrying line L2 of the certain continuous transportation vehicle T of conveyance speed ranks, the action of catching up with after chassis Tcu pulls up to the rear end chassis that the rear end chassis Tre with this carrying line L2 is separated in updrift side describes.As mentioned above, the friction roller 17 that rotation drives contacts with drive surface 10, to catch up with chassis Tcu than the fireballing speed conveyance of the conveyance of second carrying line, after the rear end chassis Tre that goes ahead of the rest that pulls up to as shown in Figure 2, the speed of catching up with chassis Tcu that the friction roller 17 of the friction-roller type actuating device 3 by catching up with usefulness drives earlier, become conveyance speed with the carrying line L2 of the ranks of certain continuous transportation vehicle T of conveyance speed, therefore, the friction-roller type actuating device 3 that catches up with usefulness is acted on the push-pull effort of upstream direction.
Here, needing will be as the application of force of the cylinder 12 of force application apparatus, it is little to set the multiply each other friction force that produced of the vertical resisting force that puts on contact surface than being contacted with the drive surface 10 of catching up with chassis Tcu by friction roller 17 and friction coefficient for, and still, friction force is by the variations such as state of contact surface.Therefore, if use as the cylinder 12 of force application apparatus, then by the air fed pressure of adjustment, and can easily suitably be adjusted the application of force.
If to above-mentioned updrift side effect push-pull effort, the friction-roller type actuating device 3 that then catches up with usefulness is movably along the conveyance direction of aforesaid chassis T, support by linear guidance device 11,11 as guiding device, by side (arrow A among the figure) application of force as the cylinder 12 of force application apparatus and downstream, therefore, the opposing application of force of cylinder 12 and upstream direction (arrow B among the figure) moves.
Like this, according to the velocity contrast that catches up with chassis Tcu and rear end chassis Tre, the friction-roller type actuating device 3 that catches up with usefulness can upstream direction (arrow B among the figure) move, so, because the rotative speed of friction roller 17 does not produce deviation with the actual speed of catching up with chassis Tcu, then make friction roller 17 and catch up with between the drive surface 10 of chassis Tcu not produce slip.Therefore, can suppress the wearing and tearing of friction roller 17.In addition, because can then can not improve the durability of this reductor from the excessive torque of reductor effect of load side to using the actuating device 16 of friction-roller type actuating device 3.
In addition, as shown in Figure 3, limit switch 31a, 31b are installed, operating body 20a, 20b before and after being equipped with in the right back end of mobile foundation 9 in the right back end of permanent seat 8.Therefore, can detect the front and back position that the friction-roller type actuating device 3 that catches up with usefulness is stipulated when the conveyance direction moves.
Especially, chassis T ... have under the situation of adaptor union, if after catching up with chassis Tcu and pulling up to rear end chassis Tre, chassis Tre is connected with the rear end, then needn't provide propulsive effort to catching up with chassis Tcu because catch up with the friction-roller type actuating device 3 of usefulness, therefore, can further reduce to catch up with the shift motion of friction-roller type actuating device 3 upstream direction of usefulness.
Chassis T ... do not have under the situation of adaptor union, after catching up with chassis Tcu and pulling up to rear end chassis Tre, catch up with chassis Tcu up to driving by chassis carrying device 2, the friction-roller type actuating device 3 that need catch up with usefulness drives and catches up with chassis Tcu.Like this, chassis T ... do not have under the situation of adaptor union, as long as detection drives the state that catches up with chassis Tcu by chassis actuating device 2 sensor is set.The sensor of limit switch etc. can be set in the position that chassis actuating device 2 drives the state that catches up with chassis Tcu particularly.
This sensor is set, detecting when catching up with the state that chassis Tcu driven by chassis actuating device 2, if the piston rod 21b of cylinder 21 shrinks, friction roller 17 separates with the drive surface 10 of catching up with chassis Tcu, then because can suppress the wearing and tearing of friction roller 17, can't increase actuating device 16 loads, so, even at the chassis T that forms with compressive state without adaptor union with certain continuous conveyance of conveyance speed by chassis actuating device 2, the carrying line of ranks in, also can reduce to catch up with the shift motion of the friction-roller type actuating device 3 of usefulness in the conveyance direction.Like this, owing to can shorten the sliding distance of linear guidance device 11 and the flexible stroke of cylinder 12, therefore, can realize the densification and the cost degradation of friction-roller type actuating device 3.
