Description

But the roller conveyor that centering is regulated

Technical field

The utility model relates to a kind of roller conveyor, but the roller conveyor that specifically a kind of centering is regulated.

Background technology

At present, on the roller conveyor aligning gear need be set usually, make article move by required throughput direction.This aligning gear generally adopts the cross roll road in certain section of conveyer, and the article oblique line is carried, the straight line conveying of keeping to the side again, thus reach the alignment of keeping to the side.The major defect of this version is: the alignment of can only keeping to the side, and can not align center.And the different article of oad, line of centers is again on the straight line when keeping to the side.On the article delivery line for the needs detection; Its detection probe be arranged on usually article through the time the center above or below; If article center-biased one side through the time, can cause detecting inaccurate, generally can only readjust probe installation location in this case; Just can guarantee to detect accurately, therefore make troubles to use.

Summary of the invention

But the purpose of the utility model provides the roller conveyor that a kind of articles conveyed centering is regulated, can be with article operation along the travel line center, to be fit to the detection needs of different in width article on same travel line.

The utility model is achieved in that and comprises frame, roller-way and actuating device; Frame is provided with the aligning gear in the middle of the articles conveyed guiding roller-way; Said aligning gear is formed along the vertically disposed belt feeder of article delivery direction by two; Each belt feeder comprises three vertically disposed cylinders, adhesive tape and adhesive tape tightening device, and first cylinder is fixed on the frame of article upstream end, and second, third cylinder is fixed on the travel(l)ing rest along the article delivery direction; Make the segment of tape between second, third cylinder be parallel to the article delivery direction, said travel(l)ing rest is fixed on the frame along roller-way longitudinal travel adjustable ground.Adhesive tape between first, second cylinder of two belt feeders forms guide section to intermediate, inclined; Adhesive tape between second, third cylinder is parallel to each other and forms the stage casing; At the article of roller-way upper offset one side by this side guide section adhesive tape guiding operation rearward through passing through in the middle of the adhesive tape of stage casing, thereby realize that centering regulates.Because both sides can be by the travel(l)ing rest position adjustments to the width in the middle of the adhesive tape of stage casing, thereby the centering that can be fit to the different in width article is detected needs.

Said adhesive tape tightening device comprises spring and permanent seat thereof; Permanent seat is fixed on the frame of first drum front end; First rolling stand is fixed on the frame along article delivery direction displacement adjustable ground, and both ends of the spring is separately fixed on the permanent seat and first rolling stand.This tensioning device structure is simpler, is convenient to install.

A preferred version of the utility model is: the roller-way below is provided with electric double-way screw mandrel and the pilot bar that laterally arranges with roller-way; Two travel(l)ing rests of fixing two second, third cylinders of belt feeder are threaded with electric double-way screw mandrel two ends respectively, have the pilot hole that cooperates with pilot bar on two travel(l)ing rests.Adopt the electric double-way screw mandrel to drive two travel(l)ing rests and realize that synchronous backward moves; Not only easy to adjust; And be easy to adopt the rotating cycle of electrical control means accuracy control reducing motor, control the stroke of two-way screw mandrel, thereby realize the width between two parallel-segment adhesive tapes of accuracy control.

Can know that by technique scheme the utility model moves and regulates the width between the stage casing through the guide section of two belt feeders, thereby the article of various different sizes are carried out accurate centering.Simple in structure, adopt two-way screw mandrel can be synchronously accurately to regulate, the article after the centering are in the midway location of travel line, alignment deviation can be as accurate as ± 5mm in, the centering that is particularly suitable for the boxlike article is carried.

Fig. 4 be among Fig. 1 A to local enlarged diagram.

The specific embodiment

To shown in Figure 3, roller-way 2 two ends are rotatably mounted on the machine frame at two sides 1 like Fig. 1, and every side frame 1 below is provided with former and later two and supports 11,12.The actuating device of roller-way 2 comprises sprocket wheel 21 and chain 22, and motor (not drawing among the figure) drives chain 22 walkings, but drive sprocket 21 and roller-way 2 rotations make boxlike article 10 along arrow direction among the figure.

Aligning gear is formed along article delivery direction symmetry and vertically disposed belt feeder by two; Each belt feeder comprises three vertically disposed cylinders 41～43, adhesive tape 3 and adhesive tape tightening device, and first cylinder 41 is fixed on this side frame 1 of article upstream end by support 5.Be fixed with crossbeam 13 between the back support 12 of machine frame at two sides 1; Crossbeam 13 upper ends are provided with regulates the control apparatus of travel(l)ing rest 6 along roller-way 2 longitudinal travels; This control apparatus comprises electric double-way screw mandrel 7,

pilot bar

81 and 82 and two fixed supports 9; Two fixed supports 9 are separately fixed at crossbeam 13 two ends, and electric double-way screw mandrel 7 and

pilot bar

81,82 two ends are supported on respectively on the fixed support 9, and travel(l)ing rest 6 lower ends are provided with connecting panel 61; This connecting panel 61 extends to roller-way 2 belows and is fixed on the electric double-way screw mandrel 7 one terminal filament bars through being threaded; Have the pilot hole that cooperates with

pilot bar

81,82 on the connecting panel 61, when 7 rotations of electric double-way screw mandrel, connecting panel 61 moves back and forth along

pilot bar

81,82 through pilot hole.Second,

third cylinder

42,43 is fixed on the travel(l)ing rest 6 along the article delivery direction, makes second, third cylinder 42, the adhesive tape between 43 32 be parallel to article 10 throughput directions, and the adhesive tape 32 of two belt feeders is parallel to each other and forms the stage casing.First, second cylinder 41, the adhesive tape between 42 31 form guide section to intermediate, inclined.
