Description

ROLLER SUPPORT FOR CONVEYOR BELT SYSTEM Field of the Invention The invention relates to a conveyor belt system. More particularly, this invention relates to a support bar mounting apparatus that supports a conveyor belt. Still more particularly, this invention relates to a support bar mounting apparatus which is adapted to be inserted between standard supporting industrial tension rollers of the conveyor system so as to support a conveyor belt with a decrease in mechanical strength and friction. . This invention also relates to a support bar mounting apparatus having sides that can be adjusted in different widths and at different inclinations to accommodate conveyor systems of different configurations.

Problem It is common to use conveyor belts in order to move bulk materials from one place to another.

For example, in the energy plates, coal is transported from storage piles outside a location to hoppers that are in a distant processing area using a series of conveyor belts. A first REF. 147836 problem with the use of conveyor belts is the spill of material. A second problem is the air pollution that comes from the dust created by the conveyor belts. The generated dust can be volatile and can be ignited by any temperature rise or spark introduced into the environment. Spillage of material commonly occurs at a conveyor transfer point, where the bulk material is passed from a conveyor belt to a second conveyor belt. Often, the transfer involves the drop of bulk material from the first conveyor belt on the second conveyor belt. As the bulk material hits the second conveyor belt, this material is scattered and some material falls on the side parts of the second conveyor belt. Vibrations caused by nearby machinery can shake or shake the conveyor belt and can cause bulk material to spill over the edges of the belt. Air pollution is caused by the induced air flow in a conveyor belt system. The bulk material that falls or protrudes from the first conveyor belt on the second conveyor belt forms a material flow. The individual particles in the material flow transmit a mechanical resistance by friction in the surrounding air. The surrounding air begins to flow in the direction of the material flow and reaches a velocity that approximates the velocity of the flow of bulk material. This is called an induced air flow. The bulk material is suddenly stopped at the end of its fall and is compacted by impact on the second conveyor belt. The velocity pressure of the induced air flow is converted into static pressure by the impact of the material. A region of high air pressure is created by static pressure. The air that is in the region of high air pressure flows in the direction of the region of low air pressure. This air flow contains small particles of bulk material. In an open system, this air movement of the air is evident because a cloud of dust is formed which grows from a loading point of the second conveyor belt. It is common to use a housing in order to enclose the second conveyor belt in order to prevent the dust from growing and reducing spillage of material. A rubber skirt seal hangs on the lower edge of the housing and creeps against the upper surface of the inclined sides of the conveyor belt to completely enclose the area. In order to maintain contact with the rubber skirt seal and with the inclined sides of the belt conveyor surface, a support is placed below the conveyor belt. The support often includes bars or beams running in the longitudinal direction below the bottom surface of the conveyor belt along each side. Also, this support can include large rollers separated at their centers a distance of 1.20 meters (4 feet) below the conveyor belt. The bars or beams can cause excessive mechanical resistance or friction with the lower surface of the conveyor belt. This can cause an excessive load on the motor that turns the conveyor belt and / or can wear the side skirt and can also cause belt wear. The mechanical resistance could also heat general that can melt the belt or beams. With the use of large rollers separated at their centers by a distance of 1.20 meters (4 feet) or a greater distance, the belt may buckle or flex between the rollers and may cause excessive clearance between the inclined sides of the conveyor belt and The rubber skirt seal. This allows the spill of material and the shock or hitting at the points, where the material is squeezed between the slanted sides of the belt and the coating wear, where the belt buckles between the rollers. This causes damage to the conveyor belt. Solution The above problems and others are solved and with which, an advance in the techniques is achieved by the provision of a support bar mounting apparatus that is susceptible to being introduced, which has an inclined support, capable of being adjusted, inclined rollers. A first advantage of the support bar mounting apparatus is that the support moves or rocks the inclined sides of the conveyor belt at an inclination that can be adjusted to prevent spillage of material. A second advantage of the invention is that the support bar mounting apparatus has a series of inclined rollers which are supported on the lower part of the inclined sides of the conveyor belt. These rollers reduce friction between the support bar mounting apparatus and the conveyor belt. The rollers are placed with a reduced spacing between them to prevent buckling that could cause excessive clearance between the flexible rubber skirt seals and the slanted sides of the conveyor belt. A third advantage of this invention is that the angle of inclination of the sides of the support bar assembly with rollers can be adjusted, so as to allow the roller plate of the invention to be used with a range of standard conveyor corrugation angles. of the industry with infinite angle adjustments that are available between those standard conveyor angles.

The infinite angle adjustment compensates for small variations in the equipment, which is common among different manufacturers. The support bar mounting apparatus can also be adjusted in its width in order to accommodate different conveyor systems. The support bar assembly apparatus including the invention, inserted between standard support tension rolls (ie, idler rolls) on an existing conveyor belt, is designed as follows. The support bar mounting apparatus has a central portion oriented substantially in parallel and below the horizontal surface of the conveyor belt. A first support bar assembly on the left side of the belt is inclined so as to support the inclined surface on the left side of the conveyor belt. This causes the left side of the conveyor belt to tilt up and in line with a plane of the horizontal carrier surface of the conveyor belt. The left-side support bar assembly has fixed rollers in its frame with an adjustable joint that keeps the inclined side of the conveyor belt in contact with the rubber skirt seal. This reduces the mechanical strength of the conveyor belt while the left side of the conveyor belt is maintained at an inclination that creates an effective seal. A second right-side support bar assembly (similar to the left side support bar assembly) operates in the same way with respect to the sloped right side of the conveyor belt. A horizontal central portion of the support bar assembly has horizontal tension rollers placed below the belt that are used to reduce the mechanical strength therein and to provide additional support beneath the horizontal carrier surface of the belt. In order to be introduced under the conveyor belts, which have different designs from the manufacturers, the first and second support bar mounting apparatuses include an adjustment joint, which changes the angle of inclination of the rollers to accommodate the angle of the standard support tension rollers in the conveyor belt system. This adjustable articulation may include a base, a support extending upwardly from the base, and a link member capable of being moved which adjusts the rollers on each side at a desired angle of inclination and in a desired horizontal width. The support bar mounting apparatus can be fixed to a mounting bar by couplings. The side rollers in the support bar assemblies have a minimum gap between rollers. Advantageously, the side rollers are of a smaller diameter than the standard support tension rollers which lie below the belt. The minimum spacing between the side rollers and their smaller diameters reduces the amount of unsupported area that lies below the inclined sides of the conveyor belt. The side rollers are small in diameter and have precision sealed bearings in order to increase speed and reduce friction.

The vertical supports 121 are connected to the vertical skirt side walls 106. The vertical supports 121 are further connected to the horizontal skirt wall supports 109, each of which in turn is connected at its outer end with the vertical support element 105, which is connected at its lower end with the spar or vertical member 103 comprising a lower base for the conveyor system 100. The equipment provided in accordance with the present invention includes the apparatus of transport sliding support 119, of which four are shown in Figure 1. The sliding support apparatus 119 includes and the inclined rollers 110, which are shown inclined at an angle of inclination, in order to support the inclined sides of the belt 104. This inclination contains the material moved by the conveyor belt 104 while preventing spillage of material on the inclined sides of the conveyor belt 104. The apparatus provided in accordance with the present invention further includes a series of central support tension rolls 117 below the belt 104. Only one of the central support tension rolls 117 is shown in FIG. Figure 1. However, each sliding support 119 includes a central support tension roller 117. The system of Figure 1 further includes the inclined support tension rolls 116, which comprise a part of the existing conveyor system. The tension rollers 127 and 116 are positioned approximately every four feet along the extension of the conveyor belt 104. The cover 107 encloses the upper portion of the conveyor system 100 and prevents spillage of material on the sides of the belt and furthermore prevents the escape of dust generated by the movement of the material load. Dust escaping and material spillage are further avoided by the rubber strap seals 118 positioned in the upper portion of the vertical skirt side walls 106 (Figure 2), the rubber strap seals 118 and the wear lining 125 have a lower end which press against the upper part of the inclined portion of the belt 104. The tension roller support 115 supports the inclined support tension roller 116 and rests on the conveyor beam 103 of Figure 1. The Figure 2 is a front sectional view of the conveyor system 100 including a conveyor belt 104. Figure 2 discloses a platform 101, the support bar platform 123, a left side plate 102 and a right side plate 102. The side plate left 102 tilts the the left side of the conveyor belt 104 upwards in order to prevent spillage and to maintain the conveyor belt 104 against the rubber strap seal 118. The right side plate 102 tilts the right side of the conveyor belt 104 upwards so as to prevent spillage and maintain the conveyor belt 104 against the rubber strap seal 118. The support bar 123 maintains the tension rollers 117 and the carrier surface of the flat conveyor belt 104. The support bar 123 supports the conveyor belt 104. and the tension roller 117 to prevent them from deforming under the impact of material. The support bar 123 has a support surface oriented substantially parallel to the carrier surface of the conveyor belt 104. The support bar 123 supports the support bar assembly 124 and the carrier surface of the conveyor belt 104. The assembly of end support bar 124 includes the inclined rollers 110. The inclined rollers 110 and the tension rollers 117 are coupled with the support bar 123 by means of the posts 215, 204 and 205. The posts 215 and 204 are fixed to the support bar 123 by the screws 206 which are threaded through the holes in the support bar 123. The tension rollers 117 are fixed in the support bar 123. by the support 211 and the spigot 216. The left side plate is located on the left side of the support bar 123. The left side plate 102 comprises a part of the support bar assembly 124, which is subsequently described in connection with Figure 3 and includes the rollers 110, the elements 212, 122, 204, 205 all are described in further detail in Figure 3. Figure 2 has a right side plate 102 which is identical in all respects to the left side apparatus 102 The support bar assembly 124 supports the inclined lower surfaces of the belt 104 to enclose the trapped dust that is generated by the conveyor and prevent material spillage on the sides of the inclined belt. The support bar assembly 124 comprises the apparatuses listed above and can be adjusted as described in connection with Figure 3 and then in connection with Figures 5, 6 and 7 in order to allow the support bar assembly 124 to be used in different conveyor systems that have different degrees of inclination for the lateral portions of the conveyor belt. The member 212 is able to slide on the element 205 so as to allow the rollers 110 of Figure 3 to be adjusted at an inclined angle corresponding to the angle of the inclined sides of the conveyor belt. The element 212 is capable of being adjusted so as to allow all the series of rollers 110 shown in Figure 3 to be adjusted and slid in different positions in order to accommodate the conveyor belts 104 of different widths and different inclination angles. The sliding element 212 is mounted on the member 205 whose left end is rotatably connected to the element 204, which comprises a portion of the support 206. The right end of the element 205 is fixed by means of the screw 212 with one of the holes 203 in the outer hinge 122 which is a one-piece element that includes the element 122B. The lower part of 122B is rotatably fixed by means of a screw with the element 215 which comprises a part of the support 206. The support bar assembly 124, which comprises the present invention, is capable of being adjusted to be compatible with different conveyor systems. Both left and right side plates 102, as best shown in Figure 3, include member 212, the plates are slidably mounted on member 205. The sliding interaction between member capable of being moved 212 and member 205 allows that the entire support bar assembly 124, including the rollers 110, are capable of being adjusted in width in order to accommodate different belts. The support bar assembly 124, the element 212 and the rollers 110 are also capable of being adjusted with respect to their inclination angles. The tilt angle is adjusted by loosening the set screws 210 to allow the elements 212 and 205 to move relative to each other. Then, the outer hinge 122 is adjusted by rotating it around its pivot point in the element 215, and at the same time, interconnecting the bar 205 and the vertical portion of the outer hinge 122 when inserting the screw 211 through the hole 203 in the vertical portion of the outer hinge 122. Following this, the set screws 210 can then be adjusted and tightened so that the moveable member 212 is fixedly positioned with respect to the slide bar 205. Figure 2 is a sectional front view of the support bar mounting apparatus 124 shown in further detail in Figure 3. The function of the support bar assembly 124 is to support the lower horizontal portion of the conveyor belt 104 by means of the central support tensioning rollers 117 provided by the apparatus of the invention. Another function of the support bar assembly 124 is to support the inclined sides of the conveyor belt 104 with the rollers 110. Each support bar assembly 124 is capable of being adjusted in width by the fixing screws 210, which can be loosened in order to allow the member 212 to slide along the inclined slide bar 205. The support bar assembly 124 together with its rollers 110 can also be adjusted in width in order to accommodate different conveyor belts by means of loosening the screws associated with the supports 206 to slide the support bar assembly 124 to the left or right along the support bar 123 in order to accommodate conveyor belts of different widths. Following adjustment, the screws associated with the supports 206 can be tightened, such as the fixing screws 212. Each support bar assembly 124 is capable of being adjusted at different inclination angles if the screw 211 is removed from a normal hole 203 of the outer hinge 122, by rotating the hinge of a piece 122 and 122B about its pivot point in the hinge 206, by rotating the slide bar 205 about its pivot point connected with a portion of the hinge 206 and the element 215 to locate the rollers 110 of the support bar assembly 124 to an inclination that combines with the inclination of the conveyor belt. Following this, the screw 211 is then inserted into the suitable hole 203 of the vertical joint 122 to accommodate the desired inclination of the support bar assembly 124. Next, the screws and fastening screws associated with this adjustment they are tightened to fix the support bar assembly 124, in the desired width along the support bar 123, at the desired angle of inclination and in the desired position in the element 205. The support bar 123 supports the apparatus for mounting the support bar, as well as the tension rollers 117 supporting the horizontal carrier surface of the flat conveyor belt 104. The support bar 123 prevents the conveyor belt 104 from deforming under the impact of the material load. The support bar 123 and the tension roller 117 provide a support surface below the carrier surface of the conveyor belt 104. The support bar 123 also supports the inclined rollers 110 and their associated members. The conveyor system 200 of Figure 2 includes the side aprons 107 and the top cover 108. The side aprons 107 and the cover 108 are located above and enclose the conveyor belt 104. The supports 109 attach the side aprons 107 by means of the vertical members 121 with the base of the conveyor belt system 200 by means of the conveyor rails 105. The wear liners 125 are a function of the lower end of the aprons tables 107. The wear liners 125 engage with the upper portions of the conveyor belt 104 to prevent material from spilling out from the sides of the conveyor belt 104. The skirt seals 118 extend outwardly from the wear liners 125 and further engage with the conveyor belt 104. Figure 4 is a bottom side view of the elements of the support bar assembly 124. This show to the inclined support tension rollers 116 of the existing conveyor system. In addition, it shows the inclined rollers 110 of the support bar assembly 124. It further shows the supports 207 which are fixed to the ends of the support bar 123 shown in Figures 2 and 3. In addition the upper and lower supports 128A and 128B that mount the rollers 110 with the support of the support bar assembly 124. The entire assembly of this apparatus is mounted on the frame 103 referred to as the "conveyor beam", as shown in Figure 1. Figure 4 also shows the supporting tension rollers 117, which as shown in Figure 1, are oriented in the horizontal direction below the lower surface of the conveyor belt in order to provide additional support for the horizontal portion of the conveyor belt . The horizontal support tension roller 117 comprises an integral part of each element 119 in Figure 1, which is called the "sliding support". Each support bar assembly 124 includes two sliding support members 117 and thus, two horizontally oriented support tension rollers 117 furthermore of the series of inclined rollers 110. The rollers 110 are smaller in diameter than the rollers of inclined tension 116 of existing conveyor systems. This allows the rollers 110 to be spaced very little apart in order to minimize unsupported belt extension of the inclined portion of the belt 104 between the rollers 110 in order to minimize buckling of the inclined portion of the belt. This provides improved material support for the inclined portion of the belt and, as best shown in Figure 2, allows the rubber belt seal 118 and the wear liner 125 to engage with the inclined portion of the belt 104 with the purpose of reducing the escape of dust and minimizing the spillage of material on the inclined sides of the conveyor belt 104. In a preferred embodiment of the invention, the rollers 110 are of small diameter and have sealed precision bearings. This encourages the improved sealing for the conveyor belt 104, thereby preventing spillage of material. Figures 5, 6 and 7 illustrate the first side plate 102 in a variety of angles for mounting under different conveyor belts. In Figure 5, the side plate 102, shown in position 500, is at an angle of 45 degrees with respect to the plane of the carrier surface of the conveyor belt. In the embodiment shown, the first side plate 102 is placed in position 500 when a screw is inserted through the highest hole 501 in a joint member capable of being moved 122.

In Figure 6, the side plate 102 is placed in the position 600, which is at an angle of 35 degrees with respect to the plane of the carrier surface of the conveyor belt 104. In the embodiment shown, the first side plate 102 is positioned in position 600 by inserting a screw through a middle hole 601 in the connecting member capable of being moved 122. In Figure 7, the first side plate 102 is in position 700, at an angle of 20 cm. degrees with respect to the plane of the carrying surface of the conveyor belt 104. In the embodiment shown, the first side plate 102 is placed in position 700 when a screw is inserted through the lowermost hole in the connecting member capable of being moved 122. DETAILED DESCRIPTION OF FIGURE 8 Figure 8 describes the additional details of the support bar 123 of Figure 3 and how it interacts with the supports 206 and their associated screws. The single support bar 123 of Figure 3 actually comprises two sepa bars 123A and 123B of Figure 8. There is a spacing between the bars 123A and 123B which allows the screw 301 to extend downwardly through the spacing to hold together the upper and lower portions of the support 206 when the screw 301 is tightened. The front and rear screws 302 on the front and back of the plates 206 in Figure 3 can be tightened or loosened in order to rigidly control the fixation of the plates 206 with the front and rear platform bars 123A and 123B.
