Description

The present invention relates to a device for unloading

  material for the stacking or loading of boats and nalogues, which comprises a feeding member and a movable unloading member with respect to the feed member and a conveyor belt passing over a drum end arranged at the place of

the unloading organ.

  It is already known that a stacking means comprises a feed or loading member provided with a separate conveyor belt and a movable unwinding member or, more correctly, relative to the feed member and also provided with a separate conveyor belt. With a versatile discharge member with respect to the choke member, an essentially larger operating radius is obtained compared to a conventional stacking machine with integral and fully loaded feed and unloading devices. of a band of convoyour and, consequently, one can rot. IS IS large amount

  of material x dumane site of the stacking means.

  However, this advantage is achieved due to significantly higher operating costs, for example due to the fact that for the stacking means provided with a versatile offloading means, the material must first be transferred by means of the web. conveyor of the feeding member to a level where the trapping of the melt of the conveyor belt of the feed member to the

  conveyor belt of the unloading member

  by a free fall, before being able to bring this material to the desired level of unloading on the last

gang.

  The present invention therefore relates to the elimination of the disadvantage of the known stacking means provided with a pivotable unloading member, which disadvantage comes from the transfer to the top of the materials that are simply necessary for reloading, and it therefore relates to a means of stacking or

  an unloading device constructed so that no.

  To guide the leaders% 3 a. Absent: "In the case of the traction of the cowydry bend in the throat 3a of the cylindro extreme 3 and the deaerating roll 0 9, bails 35 having two or three support rollers 36 are arranged immediately on the Before the cylinder or relative roller 8, 9 see it can be seen in Figure 6. A feed bag 37 is also egregée in the feeder 1, and in this pocket passes the conveyor belt to receive material Then, the conveyor belt 3 gets closer to the shape

  of bag shown in Figure 3 through the frames 6 arranged-

  in the frame 31 and is then driven in this form until it is again separated to pass extended on the unloading roll 9 for delivery

of his charge.

  In order to be able to turn the unloading member 2

  with respect to the feed member 1, two pulleys -

  39 provided with grooves 38 corresponding to the sectional profile

  transversal elements absorbing the forces of trac-

  tion, are arranged at the end of the frame 30 facing the unloading member, and between these puulies,

  the support part 3A of the charge passes with its -

  elements 4 engaging the grooves 38 of the relative pulley and in contact with each other, and a similar pair of pulleys 40 is arranged for the return portion 3X of the conveyor belt at the end of the

  unloading 2 facing the feeding member.

  These pulleys 39, 40 are, in each pair, arranged symmetrically of the two sides of a radial vertical plane through the axis 15 around which the unloading member 2 can pivot, that is to say that the pulleys each pair have their shafts 41, 42 respectively, adapted to the same perpendicular distance of the radial plane to support the cities of the elements absorbing the forces of

  traction facing each other in this radial vertical plane.

  The pairs 39, 40 of pulleys arranged between the supply member 1 and the unloading member 2 must also be arranged in the relative member 1, 2 so that the axis 15, that is to say ie, the center of rotation of the unloading member, is placed between them when the members 1 and 2 are in line with each other v Even if a pair of pulleys can be placed at a shorter distance from the 15, it is substantially more advantageous for the two pairs 39, 40 to be placed at the same distance from the axis 15, this distance being less than the radius of the

pulleys also large.

  When the unloader member 2 pivots about the axis, the load support portion 3A and the return portion 3B of the conveyor belt extend around the relative sheaves 39, 40 and the resulting length difference.

  is so weak that it is quite negligible when

  the feeding element of 45 in each direction.

  When we turn the unloading device 45, that means

  say 900, this position being schematically illustrated in Figures 9 and 10, where the distance between the axis 15 and the relative pulleys of pulleys is illustrated to be approximately equal to the radius of the pulleys, the difference in length is somewhat greater , but this is compensated by the fact that the end cylinder is movable relative to the frame 31 against the action of a constant counterforce, for example, a counterweight now the

  conveyor belt constantly stretched.

  To guide the tensile forces absorbing elements -4 of the conveyor belt into the groove 38 of the pulleys, a roll bed 6 must be arranged immediately before the relative pair of pulleys. The frame shown in Figure 9 in the direction of movement of the belt after the pulleys is. first frame in the arrangement 29

  disposed on the b & ti 12 of the unloading member.

  At the junction between the protruding arm 17 and the extension arm 22 pivotable relative to the arm 17. two pulleys 43 similarly suspended in the protruding arm, are arranged for the support portion of the load 3A of the conveyor belt has two transmission wheels 45 arranged in an arm 44 of the extension arm 22, between which the return portion 3B of the web passes with its tensile forces absorbing elements 4 in engagement with the guide grooves 46 in one of the two return rollers 45, which guide grooves are arranged in relation

  spaced apart, so as to correspond substantially

  at the distance between the elements 4 absorbing the tensile forces of the strip in the extended state. The deflector 45 provided with the guide grooves 46 is illustrated as two discs 48 attached to a shaft 47, while the other cylinder 45. is cylindrical in shape to accommodate and support the entire width of the web at the same time. pivoting of the extending arm 22 to the right of FIG. 2. In addition, the pulleys 43 and the rollers 45 are arranged in the same manner as the knobs 9, 40 at the junction between the members 1 and 2 relative to each other. at the distance to the shaft 23, a-turn of which can rotate the arm

in extensionr-

  In the context of the invention, it is possible for the return portion of the conveyor belt to hang at its end all the way between the rollers;

  S and 9, mdisdansautrE. In this case, the advantage is gained by

  the strip after the discharge roller 9 and returning it back to its bag shape after the return rollers 45, i.e. the waste exclusion at the return portion 3B of the convoy belt, is lost. . If the band is turned it must be turned again before passing on the extreme cylinder S and a device rotating the band, not shown in detail 9 is arranged for this at the position 30 in 48 and it can consist of return cylinders same type as those designated in or cylinders supporting only one of the two

  elements 4 absorbing tensile forces.

  Instead of the end cylinder 8, on which the band goes to the extended state, a turntable 49 of the type illustrated in FIGS. 7 and 8 can be arranged around which the band 3 with its bag-holding shape will pass with an element 4. absorbing the tensile forces in contact with a separate wheel 50 at a higher level than the other element in engagement with a groove 51 of another wheel 51 of the turntable 49, the wheel 51 operating as the other wheel 50 of the tray all is freely mounted to be able to move relative to the wheel 51 and balance the difference -fitness between the elements 4 absorbing forces action.
