Abstract
In a method and apparatus for transferring bulk material in two opposite directions using a flexible tubular endless belt (1), the outward run of the belt extends in tubular form between first loading and unloading points (2, 3) positioned spaced apart. The return run of the belt is utilized for transferring another bulk material. Thus, in its return run the belt is twisted through 180 DEG after the first unloading station and before a second loading station (26) where the belt is opened to receive the second bulk material. The belt is re-closed to tubular form to carry the second bulk material to a second unloading station (5) at which the belt is opened to discharge the second bulk material. The belt is then again twisted through 180 DEG before passing to the first loading station. <IMAGE>
Description
SPECIFICATION
A method and apparatus for transferring bulk material
The present invention relates to a method and apparatus for transferring bulk material in two opposite directions using a flexible tubular belt, and more particularly relates to a method and apparatus for conveying and elevating bulk material such as powder, granule, fibres, pellet, chunks, earth, mud, sludge, pulverized material, and a mixture thereof, enclosed within a flexible tubular endless belt in two opposite directions.
Flexible tubular endless belt conveyor system for transferring such aforesaid materials is known, but in such system the tubular belt is empty during its return passage. The belts used in such a system usually comprise an outer surface layer which contacts support rollers and has a large abrasionresistance, and an inner surface layer which enwraps the bulk material. Hence, this flexible tubular endless belt cannot be ailowed to roll inside out. If this happens bulk material attached to the inner surface of the belt is dropped in the return path, thereby causing environmental contamination. Further, both sides of the tubular belt, which overlap one another along its longitudinal direction, should always be positioned uppermost so that the bulk material may not be split from the belt.However, when the belt is rolled inside out the sides of the belt cannot be so positioned.
It is an object of the present invention to provide a method and apparatus for transferring bulk material in two opposite directions using a flexible tubular endless belt, free from the aforementioned inconveniences.
According to the present invention there is provided a method for transferring bulk material to and from both ways using a flexible tubular endless belt, wherein a pipe-formed flexible tubular endless belt is extended between loading and unloading points spaced apart one another at a certain distance in any heights, and is opened at the loading and the unloading points, and wherein both side edges of the flexible tubular endless belt, overlapping one another along its longitudinal direction, are positioned upside in the going path, the improvment which comprises the steps of (a) twisting the flexible tubular endless belt passed through the unloading point through 180 degrees in the return path, (b) loading bulk material into the flexible tubular endless belt opened, (c) transferring the bulk material enclosed within the pipe-formed flexible tubular endless belt, (d) unloading the bulk material from the flexible tubular endless belt opened again, and (e) twisting again the flexible tubular endless belt through 180 degrees in the return path before the loading point.
According to the present invention there is also provided an apparatus for transferring bulk material to and from both ways using a flexible tubular endless belt, wherein a pipe-formed flexible tubular endless belt is extended between loading and unloading points spaced apart one another at a certain distance in any heights, and is opened at the loading and unloading points, and wherein both side edges of the flexible tubular endless belt, overlapping one another along its longitudinal direction, are positioned upside in the going path, the improvement which comprises (a) first twisting means which twists the flexible tubular endless belt passed through the unloading point through 180 degrees in the return path, (b) means for feeding bulk material into the flexible tubular endless belt opened, (c) means for rolling up the flexible tubular endless belt so as to wrap completely the bulk material therein, (d) support rollers which support the pipe-formed flexible tubular endless belt transferring the bulk material in the return path, (e) means for opening the pipe-formed flexible tubular endless belt, (f) means for discharging the bulk material from the opened flexible tubular endless belt, and (g) second twisting means which twists again the flexible tubular endless belt through 180 degrees in the return path before the loading point.

Referring now to the drawings, there is shown in
Figures 1 - 9 one embodiment of an apparatus for transferring bulk material in two opposite directions using a flexible tubular endless belt according to the present invention. Axes of all rollers and drums to be described are perpendicular to the direction of movement of a flexible tubular endless belt 1, unless otherwise stated.
The tubular endless belt 1 is made of a flexible or elastic material such as rubber, flexible plastics material or the like, and is formed such that in its relaxed state it adopts a tubular form, curved through appreciably more than 360 , so that its two sides are overlapped along the longitudinal direction of the belt. Alternatively a conventional flat flexible endless belt capable of being directed into tubular form can be used. The flexible tubular endless belt 1 is stretched between a lower idler drum 2 and an upper drive drum 3 which are positioned at loading and unloading points spaced apart from each other and the belt 1 is opened at the loading and the unloading points to adopt a flattened form on and around the lower and the upper drums 2 and 3.The endless belt 1 is moved in an upper outward path and a lower return path la and 1h respectively. The endless belt 1 leaving the upper drum 3 is moved in the return path 1b via a first guide roller 4, loading means 26 and discharge means 5 to be hereinafter described, and a second guide roller 6, to the lower drum 2.
As shown in Figure 1, the endless belt 1 is supported by a plurality of first support frames 7 in its middle part and by a plurality of second support frames 8 in its lower and upper end parts. The first support frames 7 and second support frames 8 are all parallel and are supported at spaced intervals by beams 9. Each first support frame 7 comprises upper and lower chambers 7a and 7b, divided by partition plates, as shown in Figure 2, and each second support frame 8 comprises an upper chamber (not shown) and a lower chamber 8a, in a similar manner to the first support frame 7, as shown in Figure 4.
A plurality of roller supports 10, each comprising a base plate 1 Oa and a pair of spaced side plates 1 Ob extending from the ends of the base plate 10a in a direction perpendicular to the base plate 10a, are arranged radially in a circular form in each chamber 7a or 7b of the support frame 7. A support roller 11 is rotatably mounted in the side plates lOb of each roller support 10, so that the support rollers 11 are arranged radially around the periphery of the tubular belt 1 and support the tubular belt 1 in contact therewith.
The belt 1, in its opened condition, is turned around the lower drum 2 from the lower return path 16 to the upper outward path la, and then is closed gradually into its tubular form by its own restoring force aided by support with guide rollers 12 and 13 on its bottom and both sides, while a first bulk material 15 is fed onto the belt 1 from a hopper 14 which is arranged above the lower drum 2, as shown in Figure 3.
Then, the tubular belt 1, now completely enclosing the first bulk material 15 is passed through the upper chambers of the support frames 8 and then the upper chambers 7a of the support frames 7 along the outward path of the belt, the belt being supported by the support rollers 11 in the upper chambers of the support frames 7 and 8. On this occasion, the overlapping sides of the belt are situated uppermost along the outward path la of the belt 1.
Next, at the upper end of the belt conveyor, the tubular endless belt 1 is opened again gradually around the upper drum 3 by belt extension means 16 having a symmetrical construction to the belt closing means positioned in the lower end of the outward path la, as described above. The lower part of the belt is supported by guide rollers in the same manner as at the lower end of the belt 1, and the first bulk material 15 is discharged into a receiver 17 from the opened endless belt 1 as it passes around the upper drum 3.
The flattened endless belt 1 leaving the upper drum 3 is passed over the first guide roller 4, and then is again rolled into tubular form in the return path 1 b by first belt closing means 18 having the same construction as the closing means arranged in the lower end of the outward path la. The tubular endless belt 1 is then passed through the lower chambers 8a of the second support frames 8.
As shown in Figure 4, a plurality of roller supports 19, each comprising a base plate 19a and a pair of side plates similar to the plates 10 of Figure 2, and support rollers 20 are arranged radially around the lower chamber 8a of each second support frame 8 and held by bolts 22 and nuts, in the same manner as the first support frame 7 Figure 2.
In this embodiment, as shown in Figure 5, one support roller 20 on each frame 8 or a plurality of support rollers 20 (desirably all of them) on each frame is or are inclined by inserting a U-shaped spacer 21 (one embodiment of which is clearly shown in Figure 6) between the second support frame 8 and one end of the base plate of each roller support 19 and mounting them by the bolts 22 and the nuts. Each such roller 20 mounted as a twisting roller on the second support frame 8 by using a spacer 21, is inclined in the same direction at a certain angle with reference to the surface of the second support frame 8 perpendicular to the axis of the tubular endless belt 1.
Therefore, the tubular endless belt 1 passing through the lower chambers 8a of the second support frames 8 in the return path 1b is gradually twisted through 180 degrees around the axis of the tubular endless belt 1 by the twisting roller or rollers, until the overlapping sides of the tubular endless belt 1 are positioned uppermost.
Then, the tubular endless belt 1 is opened gradually, as shown in Figure 8, by belt opening means which comprises horizontal support rollers 24 supporting the central bottom of the belt 1, and inclined opening rollers 25 holding the inner side ends of the belt 1. At this time, a second bulk material 27 is fed into the opened endless belt 1 by a first belt conveyor 26 which extends in the direction perpen circular to the moving direction of the belt 1 in the return path 1b, and whose front end is positioned above the opened endless belt 1.
Then, the opened belt 1 carrying the second bulk material 27 is gradually closed into tubular form by belt closing means 28 having the same construction as the belt closing means 18 described above, with the overlapping sides of the belt positioned uppermost. The tubular endless belt 1 is then passed through the lower chambers 7b of the first support frames 7 in contact with the support rollers 11 in the lower return path 1b.
When the endless belt 1 enclosing the second bulk material 27 reaches a predetermined discharge position, the endless belt 1 is opened to flattened form by belt extension means 29 having the same construction as the belt extension means 16 described above.
The flattened endless belt 1 is moved to the discharge means 5 comprising a plurality of discharge rollers 5a, Sb, Sc and 5d, the axes of which form a trapezoidal pattern. The flattened belt 1 is thus moved downwards and around the discharge rollers 5a, Sb, Sc and 5d in a loop of the return path 1b.
A second belt conveyor 30 extends in the direction perpendicular to the direction of movement of the belt 1 in the return path ib, and its rear end is positioned in the discharge means 5 under the discharge roller 5a so that the second bulk material 27 may be transferred from the flattened belt 1 around the discharge roller 5a on the second belt conveyor 30, as shown in Figure 9.
The flattened endless belt 1 passing through the discharge means 5 is then again roller up into tubular form by belt closing means 31 which possesses the same construction as the belt closing means 18 in the return path 1 b. Then, the tubular endless belt 1 is again twisted through 180 degrees by a second twisting roller or rollers (not shown) in the same manner as the first twisting roller or rollers, as described herein before in connection with Figures 4 - 6. The overlapping sides of the belt 1 are thus positioned at the lowermost port of the belt. Then, the tubular belt 1 is opened again into flattened form by belt extension means having the same construction as the belt extension means 16 described above, and the flattened endless belt 1 is moved around the lower drum 2 via the second guide roller 6.
Although six support rollers are shown radially arranged around the periphery of the tubular endless belt in each upper or lower chamber of the support frame, it will be understood that the number of the support rollers can be varied freely as occasion demands. Further, the number of the twisting rollers can be also varied freely depending on the mechanical properties of the flexible endless belt,the number of the second supportframes, and so forth.
In Figures 10 and 11 there is shown an alternative embodiment of the belt twisting means, wherein the same reference numbers as those of the abovedescribed embodiment denote the same members as those thereof. In a lower chamber 51a of a second supportframe 51 corresponding to the second support frame 8 of Figures 4 and 5, the support rollers 11 are arranged radially around the belt 1 in contact therewith in the return path 1b in the same manner as described above. A bracket 52 is mounted on the lower beams 9 in parallel with the support frame 51 and adjacent thereto.
A U-shaped roller support 53 comprising a base
plate 53a and a pair of side plates 53b, having the same construction as the support 10 of Figure 2, is
pivotally mounted in the centre of the bracket 52 via a vertical pivot pin 54. The side plates 53b of the roller support 53 rotatably support a twisting roller 55 therebetween in contact with the bottom of the belt 1 in the return path 1b.
A mount plate 56 is integrally connected to the base plate 53a of the roller support 53, and extends horizontally in the direction perpendicular to the moving direction of the belt. To the free end of the mount plate 56 a lever 57 for pivoting the twisting roller 55 is integrally attached.
The mount plate 56 is provided with a circular arc slot 58 whose circular centre is positioned at the vertical pivot pin 54. A stop bolt 59 is passed vertically through the hole of the bracket 52 and the arc slot 58 and its screw end part beyond the arc slot 58 is engaged with a stop nut 60. The pivotable mount plate 56 is fixed with respect to the bracket 52 by screwing up the bolt 59 and nut 60.
In this embodiment, in order to twist the endless belt 1 in the return path 1b with respect to the moving direction of the belt 1,the nut 60 is loosened, and the pivot lever 57, i.e. the roller support 53 is pivoted to an appropriate angle around the pivot pin 54 so that the twisting roller 55 may be inclined with respect to the moving direction of thw belt 1. Then, the nut 60 is tightened again in order to fix the twisting roller 55 in its inclined position.
Although one twisting roller 55 is shown mounted on the bottom of the lower chamber 51a of the second support frame 51, it will be understood that a plurality of twisting rollers can be arranged in the lower chamber 5a of the second support frame 51, as occasion demands.
In this embodiment of the present invention although the second bulk material 27 may be fed to the opened endless belt 1 by using the first belt conveyor 26, a hopper (not shown) can alternatively be used instead of the belt conveyor 26. Further, the second bulk material 27 can be scraped off by a discharging plate (not shown) which crossed horizontally and diagonally over the flattened endless belt 1, instead of using discharging means 5 which comprises the discharging rollers.
In Figures 12 - 14 there is shown another embodiment of an apparatus for transferring bulk material in two opposite directions using a flexible tubular endless belt according to the present invention, which apparatus possesses the same construction as the first embodiment of the apparatus shown in
Figures 1 - 9, except that the endless belt 1 is twisted through 180 degrees in flattened form by first and second twisting means which comprise a plurality of turnover rollers, as hereinafter described in detail.
In this embodiment, after discharging the first bulk material 15 from the opened endless belt 1 into the receiver 17 around the upper drum 3, the flattened endless belt 1 is passed over the first guide roller 4, third guide rollers 65, and a tension roller 66 into the return path 1b. The tension force is given to the tension roller 66 by a weight 70 which is hung on the tension roller 66 via a pivot shaft.
After passing around the third guide roller 65, the flattened endless belt 1,the inside surface of which initially faces downwards, is gradually twisted or turned over through 180 degrees by the first twisting means, which cmprises airs of first turnover rollers 67. Each turnover roller 67 is provided with flanges 67a in its both ends, which prevent the flexible belt from slipping off the rollers. Each pair of turnover rollers 67 holds the flattened endless belt 1 therebetween. The inclination angle of each pair of turnover rollers 67 is increased gradually in one direction as the endless belt 1 is passed therethrough in the return path 1b, as clearly shown in Figure 13.
This turnover of the flattened endless belt 1 is usually carried out in a distance which is approximately twenty times as long as the width of the belt 1, although this distance can, of course, be varied as occasion demands.
Once the flattened endless belt 1 has been turned over so that its inside surface faces upwardly, the second bulk material 27 is fed onto the belt by the first belt conveyor 26, in the same manner as the first embodiment, as shown in Figure 14.
The endless belt 1 is then closed to tubular form to enclose the second bulk material 27, which is moved on the belt to the discharge means 5 through the lower chambers 7b of the first support frames 7. The second bulk material 27 is discharged from the opened endless belt 1 to the second belt conveyor 30 in the discharge means 5, in the same manner as the first embodiment.
After passing through the discharge means 5, the flattened endless belt 1 is twisted or turned over through 180 degrees by the second twisting means, comprising second turnover rollers 69, each having the same construction as the first turnover roller 67, in the same manner as the first twisting means described above in the return path 1b. Then, the turned-over endless belt 1 is returned to the lower drum 2 through the second guide roller 6.
Although the present invention has been described in some detail byway of illustration and example for purposes of clarity of understanding, it will, of course, be understood that various changes and modifications may be made in the form, details, and arrangements of the parts without departing from the scope of the present invention.
