Изобретение относитс к конвейер ному транспорту, а именно к устройствам дл переворачивани ленты коН Ъейера.The invention relates to a conveyor transport, namely, devices for turning the belt over.

Известно устройство дл переворачивани обратной ветви крнвейерной ленты на IBO с помощью направл ющих роликов, свертываиедих ленту в трубу и установленных с наклоном к плоскости , перпендикул рной оси конвейера 1A device is known for turning a reverse branch of a conveyor belt onto an IBO using guide rollers, rolling the ribbon into a pipe and installed inclined to a plane perpendicular to the axis of the conveyor 1

Недостатками этого устройства вл ютс : значительное рассто ние между соседними р дами роликов, обусловленное их взаимным расположением относительно плоской кольцевой рамы, перпендикул рной к продольной оси конвейера, позвол ющее ленте частично развернутьс , вследствие чего возможно качение-одного из роликов по торцовой.поверхности борта ленты, вызывающее повышенный износ бортов, а также сложность регулировки угла наклона роликов к плоскости кольцевой рамы роликоопоры при наладке и эксплуатации устройства в измен ющихс погодных услови х (в цел х устранени излишнего проскальзывани и регулировки величины пере .ворачиваквдего момента необходимоThe disadvantages of this device are: a significant distance between adjacent rows of rollers, due to their relative position relative to a flat annular frame, perpendicular to the longitudinal axis of the conveyor, allowing the belt to partially unfold, as a result of which it is possible to roll one of the rollers along the end surface of the board tape, causing increased wear of the sides, as well as the difficulty of adjusting the angle of the rollers to the plane of the annular frame of the roller carriages during adjustment and operation of the device in varying weather s conditions (for the purpose of eliminating unnecessary slippage and adjust the value the time necessary to re .vorachivakvdego

However, this design is complicated due to the large number of special rollers for giving the tape a tubular shape and significant wear of the edges of the tape is observed due to the increased pressure on them in the process of rolling it into a pipe.

Claims

0 which is particularly undesirable, the transfer of the tape with the load-carrying side outwards, which leads to an increase in the number of spills in the areas of overturning and on the stand, increased wear of the rollers of the device and the instability of its work. The purpose of the invention is to increase the reliability of the device and the durability of the conveyor belt. This goal is achieved by the fact that the ends of the spiral holders have adjustment screws and are located on the side of the tape edges, and the guide rollers mounted on the ends of the holders are parallel to the planes of the tape near its edges and are set tangentially to the elongated loop-like curve. FIG. i shows a device for turning the conveyor belt side view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view along arrow B in FIG. 2; in fig. 4 is a view along arrow B in FIG. 2. The device for turning the conveyor belt consists of guide rollers mounted on spiral frames (holders / shh) 2 on both sides in a checkerboard order to prevent the belt from touching the edges of the rollers. The holders 2 of the spiral rollers are suspended on the frame 3 of the conveyor near the head drum 4 so that the second and subsequent spiral roles of the co-supports (when installing several spiral roller supports on the roll section) are rotated relative to the first axis around the axis of the overturned ribbons in the direction of its twist by an angle providing the twist angle flax you ranging from 1 to Yu. Smaller angles (from 1 to) for ribbons with a metal cord, smaller (from 3 to 4) for cord ribbons and the largest (from 4 to 10 °) for rubber-fabric tapes. The rollers cover the outside with a coil with the load-carrying side inside the tape 5 so that the ends of the spiral holders with spacer elements in the form of adjusting screws 6 are located on the side of the edges of the tape. At the boundaries of the coup and the rest of the conveyor belt, the belt is supported by deflecting drums 7 and the rollers of the lower branch 8. In the tail end of the conveyor, the same holders with rollers are installed and have opposite inclination (opposite direction of the turns of the helix). When the conveyor is operating, the belt 5 guides the head 4 and the deflecting 7 reels of the conveyor, after which its reverse branch is folded with guide rollers by the side of the Inside in the form of a lemniscate loop or strophoid (horseshoes with folded ends). After the device rolls out of the device rollers, the tape is turned over onto the rollers 8 of the lower branch with a clean side. In the tail part of the conveyor belt, a similar device with the opposite direction of the turns with the helium roller roller returns to its original position. During adjustment of the device during installation and operation, the angle of inclination of the rollers is adjusted by means of spacer elements 6 of adjustable length, adjustment of the tape's torsion angle by appropriate installation of the spiral rollers against each other. Such an embodiment of the device provides a reduction in the unit pressure of the rollers of the device onto the tape, and hence an increase in its durability, as well as due to the possibility of using the rollers in the device from the upper branch of the conveyor where the tape is turned, which greatly simplifies the operation of the device and reduces its cost. . In addition, the stability and reliability of the device is improved due to the fixed position of the tape in the device and the absence of a change in the torsion angle Y, depending on its rigidity, and the amount of load spilling at the coup area and along the conveyor belt is reduced, since the transfer of the tape to the rollers is avoided. and reduced edge deformations. Apparatus of the Invention A device for inverting a conveyor belt comprising guide rollers arranged around a transversely folded belt inclined to a two-row perpendicular axis of a conveyor plane in a staggered order on both sides of the holders made in the form of spiral turns, the ends of which are wedge-shaped They are spacers, characterized in that, in order to increase the reliability of the device and the durability of the conveyor belt, the ends of the spiral holders have adjustment screws and are located side edges of the belt and guide rollers mounted on the ends of the holders, parallel to the planes of the tape near its edges and installed tangentially to an elongate loop curve.
