Before any detailed explanation of the embodiments of the invention, it should be understood that the invention is not limited, in its application, to the construction details and to the arrangements of elements presented in the following description or illustrated in the drawings below. The invention has other embodiments and can be implemented in various ways.
Let us examine Figure 1, on which is shown a high inclination conveyor 10 having a frame 14, a lower continuous conveyor belt 18, an upper continuous conveyor belt
22, and pressing assemblies
26.
The continuous conveyor belt and the upper continuous conveyor belt 22 are arranged in an endless sandwich configuration for conveying a product 30 (FIG. 3) between the lower conveyor belts with strong inclinations relative to the horizontal. For example, the high inclination conveyor 10 can transport a product on a very steep conveying slope which can
If going to the vertical, that is 90 °.
we examine Figures 1 to 3, the chassis 14 of the steep conveyor 10 extends at an angle to the horizontal and comprises upper chassis elements 34 and side chassis elements 38. In certain modes of embodiment, the frame 14 can include a staircase 42 which goes up along the lower and upper conveyor belts
18, 22. Sets of idler rollers 46 are positioned under the lower conveyor belt 18.
The idler rollers 46 comprise each of the idler rollers which rotate in abutment on a deflection frame 54.
In the embodiment shown, the idler rollers 50 of each idler roller assembly are positioned so that the axes of rotation
3) idler rollers 50 are not aligned (in other words, idler rollers 50 rotate on axes 58 which are perpendicular to each other
Such an arrangement of idler rollers forms a hollow in which a product is received between the lower and upper conveyor belts
If we look at Figure 2, the lower conveyor belt like the upper conveyor belt are continuous belts.
the conveyor belt
Concretely,
lower conveyor 18 understands a band part lower conveyor 62 and a band part of lower reference 66, and the bandaged conveyor
upper 22 includes an upper conveyor belt part 70 and an upper return belt part
74. The lower deflection strip part 66 is supported on lower strip support rollers 78. The upper deflection strip part 74 is supported on upper strip support rollers 82 coupled to the chassis 14.
To return to FIGS. 1 to 3, the pressing assemblies 26 are coupled to the chassis 14 and urge the upper conveyor belt 22 towards the lower conveyor belt 18, as we explain in more detail below. Each of the pressing assemblies 26 comprises a fixing bracket 86 pivotally coupled to the frame 14. The fixing bracket 86 comprises an A-structure 90 and a roller support 94. In the embodiment shown, the A-structure 90 is pivotally coupled to the frame 14 and the roller holder 94 is pivotally coupled to the structure at A 90. The roller holder 94 pivotally supports pressure rollers 98 which are engaged with the upper conveyor belt 22 In the embodiment shown, the pressure rollers 98 are arranged in two rows (Figure 2), with four pressure rollers 98 in each row (Figure 3). Concretely, the roller support 94 comprises articulations 102 which rotate the pressure rollers 98.
Each of the pressing assemblies 26 further comprises a spring support 106 coupled to the chassis 14. In the embodiment shown, the spring support 106 is fixed to the upper chassis element 34 by a welding operation, for example. The spring support 106 includes bolts 110, an upper plate 114, and a lower plate 118 which is adjustably positioned relative to the upper plate 114 by adjusting nuts 122 corresponding to the bolts 110. A spring 130 is included in each of the pressing assemblies and is positioned between the fixing bracket 86 and the chassis
14. In the embodiment shown, the spring 130 is positioned between the fixing bracket 86 and the spring support 106.
The spring support 106 further comprises a cylindrical seat 126 (ie an upper spring seat) extending from the lower plate 118, in which an upper end of the spring 130 is received. shown embodiment, the cylindrical seat 126 is aligned coaxially with the spring 130. Similarly, the fixing bracket 86 of the pressing assembly 26 comprises a lower cylindrical spring seat 134 in which is received one end spring 130. In the embodiments shown, the spring 130 is positioned inside the cylindrical spring seats 126, 134 (that is to say installed in the latter), but in other embodiments. embodiment, the spring 130 can be positioned around the cylindrical spring seats 126, 134 (that is to say outside of the latter; see, for example, the spring seat 126B in FIGS. 5-6) . The spring 130 pushes the fixing bracket 86 and the pressure rollers 98 towards the upper conveyor belt 22 (that is to say towards the upper conveyor belt part 70 and away from the spring support 106) so that the assembly pressing 26 urges the upper conveyor belt 22 towards the lower conveyor belt 18, fixing the product 30 therebetween. By adjusting the position of the lower plate 118 relative to the upper plate 114 by means of the nuts 122 and the bolts 110, the degree of prior tensioning of the spring
130 can be adjusted by an operator.
In other words, the degree of compression exerted on the spring 130 in a state of rest of
The pressing assembly can be adjusted by repositioning the lower plate 118 with respect to the upper plate 114. In certain embodiments, the repositioning of the plate to mount and initially position the spring
130 between the cylindrical spring seats 126, 134.

structure and inclination No. 4 609 091 of the company Continental Conveyor and Equipent Company,
As long as it is used within the limits of the capacities indicated by the manufacturer, a high inclination conveyor works correctly and in accordance with its design standards. However, operational problems may arise when the steep conveyor is loaded beyond its nominal capacity (i.e. outside the limits of the capacities indicated). For example, in some cases, a large object whose size exceeds the maximum size limits is placed between the upper and lower conveyor belts 18, 22. When a large quantity of product 30 or a bulky object is positioned between the conveyor belts 18, 22 and pass under the pressing assemblies 26, the spring 130 undergoes excessive compression. When in excessive compression, the spring 130 is pushed (ie ejected) out of the upper and lower spring seats 126, 134. In other words, when the pressing assembly deviates from excessively in order to receive a bulky product 30, the spring 130 compresses to such an extent that the restoring force generated by the spring 130 suddenly causes the spring 130 to come out of its position (in other words, the spring 130 buckles and disengages from the seats spring 126, 134). The fact that the spring 130 detaches from the spring seats 126, 134 is undesirable because of the risk that the spring 130 will fall over long distances, and cause damage and injury. This problem of separation of the spring 130 from the
spring seats 126, 134 is not an obviousness for the skilled person because in normal conditions of operation, the spring 130 is maintained properly in place. As such, the problem of the decoupling of spring 130 compared at the pressing assembly 26 to caus e of excess of
Compression is raised for the first time in this document, together with various embodiments of the invention which solve it.
Let us examine Figures 1 to 4 which represent a spring bearing cup 150 according to a first embodiment of the invention. The spring support cup 150 couples the spring 130 to at least one element among the chassis 14, the fixing bracket 86 or the spring support 106. In the embodiment shown, we see that the support cup spring 150 couples the spring 130 directly to the chassis 14 (i.e., to the upper chassis member 34). The spring support cup 150 comprises a cable 154 (a steel cable, for example). The spring support cup 150 further comprises a first lug 158 at a first end 162 of the cable 154 and a second lug 166 at a second end 170 of the cable 154. Concretely, if we refer to Figure 4, reinforcements 172 allow the first lug 158 and the second lug 166 to be fixed to the cable 154. The spring support cup 150 further comprises an eye bolt 174 coupled to the chassis
14. In other embodiments, the eye bolt 174 can be any suitable fastener to which the second end 170 of the cable 154. Can be fixed. In still different systems, the cable 154 can be a high resistance cable. with a nylon coating (for example an aviation cable), a cable tie or any other suitable cable of sufficient strength.
Let us examine FIG. 4, in which the first lug 158 is coupled to the spring 130 and the second lug 166 is coupled to the eye bolt 174. Concretely, the first lug 158 is positioned around a part of circular section 178 of the spring 130 of so that the first terminal 158 and the corresponding cable 154 are designed to move relative to the spring 130 without causing excessive wear by friction. Likewise, the second terminal 166 is positioned around a circular section portion 182 of the eye bolt 174 so that the second terminal ίο
166 and the corresponding cable are designed to move relative to the eye bolt 174 without causing excessive wear by friction. As such, the first end 162 of the cable 154 is coupled to the spring 130 and the second end 170 of the cable 154 is coupled to any fixed structure adapted around the spring 130. For example, in still different embodiments, the second end 170 of the cable 154 is coupled either to the fixing bracket 86 or to the spring support 106.
Because of the spring support cup 150, the spring 130 is held in the location which surrounds the spring support 106 and the fixing bracket 86. As such, if the spring 130 is detached from the spring seats upper and lower 126, 134 due to the passage of an excessively bulky product in the high inclination conveyor 10, the spring 130 will remain fixed to the rest of the high inclination conveyor 10 by the spring bearing cup 150. In this way , the spring 130 will not be in free fall but will on the contrary be fixed (that is to say anchored) on the zone located directly around the spring 130 (that is to say the chassis 14, the spring support 106, the mounting bracket 86 etc.).
Let us now examine Figures 5 and 6, which show a spring bearing cup 250 according to a second embodiment of the invention. The spring support cup 250 includes a fastener 254 (for example an L-bolt). The L-bolt 254 includes a first end 258 coupled to the bottom plate 118 of the spring support 106 and a second end 262 coupled to a cylindrical spring seat 126B. In other words, the L-shaped bolt 254 extends between the lower plate 118 and the cylindrical seat 126B. The cylindrical spring seat 126B is similar to the cylindrical spring seat 126 of Figures 1 to 4, except that the cylindrical spring seat 126B has a smaller diameter, so that the spring 130 is positioned around the cylindrical spring seat 126B.
Still in connection with FIGS. 5 and 6, the first end 258 of the L-shaped bolt 254 is threaded and passes through a hole 266 formed in the lower plate 118. A corresponding nut 270 fixes the first end 258 to the lower plate 118. The second end 262 passes through a hole 278 formed in the cylindrical spring seat 126B. In the embodiment shown, the hole 266 and the hole 278 have a diameter greater than that of the L-bolt 254, so that the L-bolt 254 can be assembled, for example, by first inserting the second end 262 in hole 278, then inserting the first end into hole 266. Thus, the L-shaped bolt 254 enters an interior space 282 (FIG. 6) defined by an external periphery 286 of spring 130. In other words, a part L-shaped bolt 254 enters the spring 130 (i.e. passes between the turns of the spring). Like the spring support cup 150, the spring support cup 250 maintains the spring 130 in the location which surrounds the spring support 106, fixing the spring 130 to the rest of the high inclination conveyor 10.
Let us now examine Figures 7 and 8 which show a spring support cup 350 according to a third embodiment of the invention. The spring support cup 350 comprises a U-shaped fixing bracket 354 having a first branch 358, a second branch 362, and an intermediate part 366 extending between the first branch 358 and the second branch 362. The intermediate part 366 of the U-shaped fixing bracket 354 extends through the spring 130 and the first branch 358 and the second branch 362 are each coupled to the cylindrical seat 126 of the spring support 106. In particular, fasteners 370 fix the first and second branches 358, 362 to the cylindrical seat 126. The intermediate part 366 partially covers an opening 128 defined by the cylindrical support 126 in which the spring 130 is received. Thus, once the spring bearing cup 350 is assembled, the spring 130 is fixed to the spring support 106. Like the spring support cups 150, 250, the spring support cup 350 keeps the spring 130 in the location which surrounds the spring support. spring 106, fixing the spring 130 to the rest of the high inclination conveyor 10.
Let us now examine Figures 9 and 10 which represent a spring support cup 450 according to a fourth embodiment of the invention. The spring support cup 450 includes a fastener 454 (in this case, an L-bolt). The L-bolt 454 includes a first end 458 coupled to the bottom plate 118 of the spring support 106 and a second end 462 coupled to the cylindrical spring seat 126. In other words, the L-bolt 454 extends between the bottom plate 118 and the cylindrical seat 126. In the embodiment shown, the spring 130 is received in the cylindrical seat 126. The first end 458 of the L-bolt 454 is threaded and passes through a hole 466 formed in the center of the bottom plate 118. A corresponding nut 470 fixes the first end 458 to the bottom plate 118. The second end 462 passes through a hole 478 formed in the cylindrical spring seat 126. In the embodiment shown, the hole 466 and the hole 478 have a diameter greater than that of the bolt in L 454 to facilitate assembly. Thus, the L-bolt 454 enters an interior space 482 (FIG. 10) defined by an external periphery 486 of the spring 130. In other words, part of the L-bolt 454 penetrates into the spring 130 (that is to say passes between the turns of the spring). Like the spring support cups 150, 250, 350, the spring support cup
450 maintains the spring 130 in the location which surrounds the spring support 106, fixing the spring 130 to the rest of the high inclination conveyor 10.
The various features and advantages of the invention are set out in the claims below.
Of course, the invention is not limited to the embodiments described above and shown, from which other modes and other embodiments can be provided, without going beyond the ambit of the invention. .
