Description

Technical Field

[0001] This disclosure relates to a material handling apparatus, and more specifically to a material handling element, such as an impeller, hammer, blade, or paddle having at least one removable element. Background Technology

[0002] For example, mixing, blending, crushing, and sorting operations are common in material handling and manufacturing across a wide range of industries and applications. These processes can be performed by hand or machine and can utilize various agitation modes to blend materials (e.g., rotation, vibration, etc.). For instance, mixing machines typically use rotating or otherwise moving elements or impellers (e.g., paddles or blades) to combine materials together. Due to the typically harsh properties of the materials being mixed and the operating parameters (e.g., mixing time, speed, etc.), wear on these elements can be significant. Therefore, these elements must be replaced quite frequently. In addition to being expensive, routine replacement of these elements can be time-consuming and thus limit overall processing output and efficiency.

[0003] Furthermore, wear on components may be uneven because the operating forces acting on the component tend to be highest at its leading edge and distal end. Therefore, replacing the entire component may be an unnecessary waste. Similarly, the mechanical and physical requirements for certain features or areas of a hybrid component may differ from those for others. In this way, integral components, as found in the prior art, may not be optimal. For example, materials such as stainless steel may be preferred for strength and corrosion resistance in the body of the component and its mounting area (e.g., where the component is attached to the rotating spindle of a machine). In other words, it may be desirable to form the ends, tips, and / or leading edges of the component from a harder and / or more wear-resistant material (e.g., hard tungsten carbide).

[0004] Therefore, an improved component is desired to address the aforementioned shortcomings. Summary of the Invention

[0005] According to embodiments of this disclosure, an element, such as an impeller or impeller assembly, includes a body adapted for operative connection to a material handling machine, and an end removably attached to the body. The body and the end define a first lateral side adapted to impact a leading edge of a material to be mixed, and a second rear lateral side opposite the first lateral side. A plurality of mounting elements removably secure the end to the body. At least a portion of each mounting element extends from the second lateral side through the body and engages with the end.

[0019] Exemplary embodiments of this disclosure will now be described in detail with reference to the accompanying drawings, wherein similar reference numerals denote similar elements. However, this disclosure may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concept of this disclosure to those skilled in the art.

[0020] In the following detailed description, numerous specific details are set forth for illustrative purposes in order to provide a thorough understanding of the disclosed embodiments. However, it will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and apparatuses are illustrated schematically to simplify the accompanying drawings.

[0021] Embodiments of this disclosure include rotating elements, impellers, paddles, or blades adapted for mounting to a machine (e.g., to its rotating output). The element includes a body formed of a first material (e.g., stainless steel) and at least one replaceable end or tip removably attached to the body. The replaceable end may be formed of a second material different from the first material (e.g., hard tungsten carbide). The end defines at least a portion of the leading edge or working surface of the element adapted to contact the material during operation (e.g., mixing, dispersing, milling, etc.). In one exemplary embodiment, the end is secured to the body via one or more fastening devices or fasteners or a fastener system including multiple fasteners. More specifically, the body defines a through-extending fastener opening. The fastener opening includes an open first end remote from the replaceable end and adapted to receive a fastener, and an open second end formed through a mating surface of the body or leading to a mating surface of the body. The fastener opening of the body aligns with a corresponding opening or hole formed in the replaceable end (e.g., a threaded opening formed into an insert embedded in the replaceable end). The fastener is adapted to be inserted into a first end of a fastener opening in the body and engages with an opening in a replaceable end. The engagement of the fastener with the replaceable end (e.g., a threaded connection) is adapted to pull the end abutting against the body to selectively secure it to the body.

[0022] Overall reference Figure 1The diagram illustrates a simplified exemplary element, impeller, paddle, or blade 10. Element 10 includes a body 12 and a pair of removable and / or replaceable ends or tips 50. Element 10 can be described as having two sides 13, 15 arranged opposite each other in the longitudinal direction relative to the center of the element. It should be understood that, apart from their different orientations about the longitudinal axis, the longitudinal ends or sides 13, 15 of element 10 may be identical to each other. Therefore, the applicable description herein will equally apply to either side 13, 15. Sides 13, 15 may be discrete elements each having a body 12 operatively connected to each other, or sides 13, 15 may be formed as a single element having a common body 12. While exemplary embodiments include two replaceable ends 50, it should be understood that the number of replaceable ends may vary (e.g., 1, 3, etc.) without departing from the scope of this disclosure. Furthermore, while exemplary ends 50 are each removable, in other embodiments, one or more ends or tips can be non-removably secured to the body 12 (e.g., integrally formed with or bonded to the body).

[0023] The body 12 defines a centrally located, generally circular opening or drive feature 14 adapted to receive, for example, a drive spindle of a material handling machine. One or more keyways or splines may be defined within the opening 14 to engage with a corresponding drive key or keyway of the machine spindle, thereby rotatably driving the element 10. The body 12 also includes a tapered surface 11 that defines portions of the leading edge or working surface of the element 10. Similarly, replaceable ends 50 may each include a tapered surface 51 that defines the remainder of a corresponding one of the leading edges of the element 10. Specifically, each end 50 and the tapered surfaces 51, 11 of the body 12 define a continuous, consistent leading edge of the element 10, wherein the end is attached to the body. In this way, the element 10 can be substantially oriented (i.e., adapted to rotate in one direction during operation). As shown, the tapered surface 11 is formed only on each distal end of the exemplary body 12. In other embodiments, the tapered surface 11 may extend over the entire length of each side 13, 15 of the element 10 (i.e., half the total length of the element). In some other embodiments, the front edge portion of element 10 may not be defined by body 12, but may be defined only by end portion 50.

[0024] like Figure 1As shown, the lateral side of element 10 opposite the front edge in the width direction W may include a rear side or edge 17, which may be oriented substantially vertically between the top and bottom surfaces of the body 12 and / or end 50, and may not define a taper. In other embodiments, the tapered front edge of element 10 may be formed on each of its lateral sides. In this embodiment, element 10 can be used to act on or process material in two rotational directions without requiring reorientation of the element relative to the machine.

[0025] Still referencing Figure 1 In some embodiments, the width of the body 12 and the end 50 in the width direction W may be substantially constant over the length of the element 10. However, in other embodiments, the width of the element 10 may taper from the center or opening 14 along its length in each outward radial direction. The same can be true for the thickness of the element 10 (i.e., it may be constant, tapered, or otherwise varied). Furthermore, in the exemplary embodiment shown, each end 50 defines only a portion of the end or free end of the element 10 in the width direction W. This embodiment may be mechanically advantageous because the tapered surface 51, which is generally perpendicular to the end 50, functions and the forces acting on the tapered surface are directly counteracted by the body 12, thereby reducing stress or strain on the mounting element, which is secured to the body by the mounting element. However, in other embodiments, each end 50 may form the entire distal end of the element 10 in the width direction W.

[0026] Now for reference Figures 2 to 4 An exemplary mounting system or arrangement 100 according to a first embodiment is shown for attaching each end 50 to the body 12 of element 10. Specifically, system 100 includes a plurality of mounting elements including a first fastener 102 (e.g., a hex socket head cap screw or headed screw), a second fastener 104 (e.g., a second hex socket head cap screw), a pair of inserts 106, 107 (e.g., threaded Invar plugs), and a pair of locating pins 108 (e.g., slotted spring pins) disposed between the first fastener 102 and the second fastener 104. Body 12 defines two through holes 110, 111 formed in rear edge 17. As shown, each through hole 110, 111 may be a countersunk hole or a countersunk hole for receiving the head of each of fasteners 102, 104.

[0027] A pair of corresponding openings 151, 152 are formed in the end 50 and coaxially aligned with the through holes 110, 111. Inserts 106, 107 are arranged in the corresponding openings of openings 151, 152 and are adapted to receive and threadedly engage the end of each of fasteners 102, 104. The use of metal inserts 106, 107, particularly Invar alloy inserts, provides a temperature-stable, high-strength threaded component to which fasteners 102, 104 can be repeatedly and removably (i.e., threadedly) engaged. In one embodiment, the first fastener 102 is larger (e.g., longer and / or larger in diameter) than the second fastener 104. This can be achieved by tapering the thickness and / or width of element 10 near its end.

[0028] The pair of pins 108 are arranged in openings 112, 113 defined in the body 12 and corresponding coaxial alignment openings 153, 154 defined in the element 50. The pins 108 are used to accurately position the end 50 relative to the body 12 and provide additional strength and stability to the mounting system 100. Furthermore, the pins 108 allow the end 50 to be precisely positioned onto the body 12 before insertion and engagement of threaded fasteners. This improves the ease of assembly of the element 10 (e.g., during replacement). As described in more detail herein, those skilled in the art will recognize that only one pin 108 may be used instead of two pins, or in some other embodiments, no pins may be used at all.

[0029] like Figure 3 and 4 As shown, through holes 110, 111 and openings 112, 113 lead to a generally vertical sidewall or mating surface 121 of the body 12. The sidewall 121 extends generally in the longitudinal or length direction of the body 12. A second vertical sidewall or mating surface 122 is oriented generally perpendicular to the sidewall 121 and extends generally in the width direction W of the body 12. Those skilled in the art will recognize that the angle between sidewalls 121 and 122 can also be acute or obtuse. The first sidewall 121 and the second sidewall 122 define a cavity 125, the dimensions of which are configured to receive an end 50 or complement the end. Similarly, the end 50 defines a corresponding vertical sidewall or mating surface 155, 157 adjacent to the respective sidewalls of sidewalls 121, 122. As shown in the figure, each of the openings 151, 152, 153, and 154 leads to the sidewall 155 for coaxial alignment with the through holes 110 and 11 and the openings 112 and 113 of the body 12.

[0030] Now for reference Figures 5 to 7 Another embodiment of a mounting system or arrangement 200 for attaching end 50 to body 12 of element 10 is shown. Similar to Figures 2 to 4In one embodiment, system 200 includes a plurality of mounting elements, including threaded fasteners 102, a pair of locating pins 108, and the same associated through holes 110 and openings 112, 113, 151, 153, 154 as described above. The second threaded fastener 104 and associated insert 107 of the previous embodiment have been replaced with a retaining screw 201. Specifically, the countersunk through hole 111 of the previous embodiment has been replaced with a threaded through hole 211 into which the retaining screw 201 can be threadedly engaged. End 50 defines a corresponding coaxial alignment opening 252 adapted to receive the end of the retaining screw 201. In one embodiment, the retaining screw 201 defines a conical head, and the opening 252 defines a corresponding tapered opposing face or bottom wall 252', as... Figure 5 and 7 As shown in the image. Similar to... Figures 2 to 4 In one embodiment, each of the openings and through holes is formed in and / or leads to the same opposing sidewalls 121, 155 of the body 12 and the end 50.

[0031] Figures 8 to 10 Another embodiment of a mounting system or arrangement 300 for attaching end 50 to body 12 of element 10 is shown. System 300 includes a plurality of mounting elements, said plurality of mounting elements including identical second threaded fasteners 104 and corresponding through holes 111, and according to Figures 2 to 4 The embodiment includes an opening 152 and an insert 107. Similarly, a pin 108 and corresponding openings 112, 113 and 153, 154 for the body 12 and the end 50 are also provided. Figures 2 to 4 The first fastener in the embodiment has been replaced with fastener 302.

[0032] The fastener 302 extends at an angle or at an incline relative to the width and / or length direction of the element 10. In one embodiment, a countersunk through-hole 310 is formed from the rear edge 17 toward the end 50 at an angle δ of approximately 45 degrees to the longitudinal axis of the element 10 through the body 12. A corresponding coaxial alignment opening 351 is formed into the element 50, and similarly fitted with an Invar alloy or metal insert 306 suitable for threaded engagement with the fastener 302. The angled nature of the fastener 302 provides additional traction at the end 50, thereby... Figures 2 to 7 The embodiments do not implement a method that pulls sidewalls 122 and 157 into adjacent contact. Therefore, Figures 8 to 10 The embodiments provide means of generating compressive forces between each of a pair of opposing sidewalls 121, 122, 155, 157, thereby improving the strength and stability of the connection between end 50 and body 12.

[0033] Similarly, Figure 12 Implementation examples include those similar to those described above. Figures 8 to 10 The described features, and more specifically, include multiple mounting elements comprising threaded fasteners 104 and inclined fasteners 302. However, with Figures 8 to 10 Unlike the previous embodiment which utilized a pair of pins 108, this embodiment uses only a single pin 108 between fasteners 104 and 302. As in the previous embodiment, the pin 108 is arranged between opposing sidewalls 121 and 155 and provides similar strength, stability, and positioning benefits. However, this configuration simplifies manufacturing, assembly, and replacement operations and reduces overall component and production costs.

[0034] Figure 11 Another improved embodiment of a mounting system or arrangement 400 for attaching end 50 to body 12 of element 10 is shown. Similar to Figures 8 to 10 In one embodiment, system 400 includes a plurality of mounting elements, the plurality of mounting elements including a second threaded fastener 104 and corresponding through holes 111, openings 152 and inserts 107. System 400 also includes one of pins 108 and corresponding openings 113, 154 formed therein in the body 12 and the end 50, respectively.

[0035] Similar to the previous embodiments, system 400 includes fasteners 402 that are oriented obliquely (e.g., at an angle δ of approximately 45 degrees) relative to the width and / or length direction of element 10. However, unlike system 300 where through-holes 310 and openings 351 open onto vertical sidewalls 122, 157 respectively, countersunk through-holes 410 and coaxially aligned openings 451 open onto opposing sidewalls 121, 155 of body 12 and end 50 respectively. In this way, all openings and through-holes are formed in or open onto the same sidewalls 121, 155 of each of body 12 and end 50. This simplifies the manufacturing process of system 400 while retaining the benefit of applying tension to end 50, which pulls the end into abutment contact with each of the opposing sidewall pairs 121, 155 and 122, 157. As shown in the figure, the opening 451 of the end 50 may also be fitted with a metal insert 406, such as an Invar alloy insert, which is adapted to receive the end of the fastener 402 by thread.

[0036] In each of the above embodiments, it should be understood that the fastener through-hole and the corresponding threaded fastener can respectively define complementary shoulders and heads, thereby limiting the depth of fastener insertion into the body 12. In this way, tightening or screwing the fastener into the insert at end 50 is operable in at least one direction of the element 10 (i.e., the width direction) and in… Figures 8 to 11In one embodiment, the end 50 is pulled in two directions (i.e., the width direction and the longitudinal direction) of the element 10. Since the threaded connection secures the end 50 to the body 12, embodiments of this disclosure provide a means for adjusting the holding force securing the end to the body. Advantageously, any loosening of the end relative to the body, depending on the difference in the coefficients of thermal expansion between the end 50 of the element 10 and the body 12, can be addressed by periodically retightening or tightening the fasteners.

[0037] In each embodiment, the first end of each through-hole is adapted to receive a tool for rotating or otherwise engaging the fastener with the end 50. The first end of each through-hole is located away from the second lateral or rear side 17 of the body 12 opposite the front edge side. In this way, during operation, material handled by the element 10 is not forcibly introduced into the opening or through-hole, nor is it necessary to remove the element 10 from the machine to access the fastener to remove the end 50. This improves reliability and cleanliness, and increases operational efficiency because the end 50 can be replaced more easily.

[0038] exist Figures 8 to 11 In this embodiment, the lateral outlets of the through holes are achieved by offsetting the central axes of the through holes 310, 410 from the central elongation axis of the body 12 by an exemplary non-zero angle δ (i.e., they are oriented obliquely or non-parallel to each other), such as 45 degrees. This ensures a relatively uniform and / or consistent clamping or compressive force between the adjacent sidewalls of the mating surfaces / faces of the end 50 and the body 12.

[0039] As described above, the end portion 50 may be formed of a first monolithic material, such as carbides, while the insert may be formed of, for example, stainless steel, Invar alloy, or other metallic materials. The insert may be secured within the end portion 50 by any suitable means, including bonding or brazing. In some embodiments, a threaded insert (e.g., a helical insert or HELI-COIL®) may be provided within the opening or insert to form a threaded connection between the end portion 50 and the threaded fastener and / or to increase its strength. In other embodiments, a separate threaded insert is not necessary, as the inherent strength of the insert material may be sufficient to provide a strong and reliable connection with the fastener (i.e., sufficient pull-out strength).

[0040] In some embodiments, the locating pin may be press-fitted, friction-fitted, sliding-fitted, or threaded into any of the corresponding openings formed in the body 12 and the end 50. The pin may be a straight pin, or it may be tapered along its length (or in each direction from its center).

[0041] Furthermore, it should be understood that the overall shape of element 10 shown in the figures is merely exemplary and may vary without departing from the scope of this disclosure. For example, the distal or free end side of each of the removable ends or tips 50 may be substantially round (as shown), or may be square or linearly angled. Similarly, the replaceable ends or tips 50 may be generally flat or planar relative to the body 12 (as shown), or may be bent vertically upward or downward, or vertically upward and downward (i.e., toward a parallel relationship with the axis of rotation of the element). In yet another embodiment, the ends may extend obliquely upward and / or downward from the body.

[0042] Elements according to embodiments of this disclosure are generally suitable for material handling operations, including but not limited to processes involving mixing, dispersing, cutting, milling, hammering, and / or agitating one or more materials (e.g., solid, liquid, and / or semi-liquid materials). Similarly, while elements described herein (e.g., mixing elements) may generally be referred to as impellers, it should be understood that this term includes blades, paddles, hammers, knives, or other similar elements or tools suitable for handling (e.g., mixing) one or more materials.

[0043] Furthermore, areas that are considered familiar to those skilled in the art have not been described herein to avoid unnecessarily obscuring the described invention. Therefore, it must be understood that the invention is not limited to the specific illustrative embodiments, but only to the scope of the appended claims.

[0044] Those skilled in the art should understand that the above embodiments are

[0045] This is illustrative and not restrictive. For example, those skilled in the art can make many modifications to the above embodiments, and the various features described in different embodiments can be freely combined with each other without conflicting in configuration or principle.

[0046] Although several exemplary embodiments have been shown and described, those skilled in the art will understand that various changes or modifications may be made to these embodiments without departing from the principles and spirit of this disclosure, the scope of which is defined in the claims and their equivalents.

[0047] As used herein, elements listed in the singular and beginning with "a" or "an" should be understood to not exclude multiple elements or steps unless such exclusion is explicitly stated. Furthermore, references to "an embodiment" in this disclosure are not intended to exclude the existence of other embodiments that also include the listed features. Moreover, unless expressly stated to the contrary, embodiments that "comprise" or "have" elements or multiple elements having a particular characteristic may include additional such elements that do not have that characteristic.
