With reference to accompanying drawing, the whole conveyer of label 1 expression, by installing 1, the reel of forming by the band material 2 winding and be sent to a uncoiling station or decoiling equipment 4 from the loading platform 3.

Reel 2 in turn is placed in from a side to opposite side on the loading platform 3, the center of reel be parallel to axis 5 coaxial alignments of loading platform 3 longitudinal sizes and be advanced to the uncoiling position 11 that occupies successively by leading reel 2 continuously, shown in the label 2a among Fig. 1.

Loading platform 3 shown in Fig. 1 has first feedway 7 to be used for supporting and advancing reel 2, and for example it is by being formed along the closed ring belt 6 that is parallel to above-mentioned axis 5 directions extension.

The top branch of belt 6 is crossed a stay bearing plate 8 (not shown) that links to each other with a frame rigidly, belt 6 is closed hoop around a preceding belt pulley 12, preceding belt pulley occupies the position that coincides with winding 11, and the position below leading reel 2a, the rear end of belt 6 also are closed hoop around the power driven belt pulley (Fig. 1 is not shown) of a routine.

Also having among belt 25(Fig. 1 and only illustrate one) side that is positioned at reel is used for carrying and also plays horizontal restriction simultaneously when reel 2 shifted to winding position 11.

Still with reference to Fig. 1, disclosed conveyer 1 has interactional first conveyer 10 with leading reel 2a, its settles and is operated in the preceding of loading platform 3 and near reel position 11, and this device 10 comprises be designed to the plant oneself actuating device of the releasing position that moves on to a bottom leading reel 2a from loading platform 3.In the example of Fig. 1, first conveyer 10 is made up of the L shaped carriage 27 of an above-mentioned belt pulley 12 and a supporting pivot 26, this belt pulley 12 is contained in rotationally and places on the spool axis 5 rectangular pivots 26, its ancon install to rotationally pivot 27 ' carriage 27 link to each other (connection mode is not shown) with stay bearing plate 8 rigidly and the pivot 26 of parallel belts wheel.Lift between position (dotting among Fig. 1) and the extended position one, by an actuator 28, carriage 27 can relative pivot 27 ' on shake, lifting the position, the foremost portion of belt 6 is positioned to the side face of leading reel 2a and contacts, extended position then the above-mentioned same area of belt 6 and the side face of reel 2a separate a distance, by second transmitting device 9 that includes support 17, make reel be seated at the position one 9 ' the position.

Or rather, hold the seat 9 of leading reel 2a ' be enclosed in being between divergent shape upper end 20a and the 21a by a pair of

diaphragm plate

20 and 21.

Seat 9 ' be positioned at the plane place that is lower than loading platform 3 horizontal surfaces, and the

plate

20 and 21 of present 9 ' two sides has been formed the part of carrier 17, rigidly connected and another plate 21 of one of them plate 20 and carrier 17 is the hinge shape by a pivot 22 and support and links to each other.

Seat 9 ' and the side face of reel between do not contact always, have only when single reel 2a arrives winding position 11 and makes reel be discharged on plate 20 and the plate 21 owing to the decline of belt pulley 12 just to come in contact between the seat and reel side face.

Device 1 also has second conveyer or release gear to represent its integral body with label 24, and whereby, in order to interrupt the support to leading reel suitable the time,

diaphragm plate

20 and 21 should be able to launch.For this purpose, by pivot 22, flap 21 links to each other with carrier 17, like this, by be connected in actuator 24 between plate (20,21) and the carrier (17) ', make the flap revolution, promptly the respective end 20a that is in more close adapter plate 20 from the upper end 21a that is divergent shape with form one 9 ' the position, forward the position that above-mentioned corresponding two

end points
