Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and more specifically, to a stacking roller chain conveying device. Background Technology

[0002] To improve production efficiency, various conveyors are commonly used in industrial assembly lines to transport goods between different workstations. For example, stacking roller chain conveyors, which use roller chains as traction and conveying components, can achieve rapid transport and stacking of goods, and therefore have gained widespread application.

[0003] The stacking roller chain conveyor is composed of multiple stacking roller chain conveying devices, each including: a track body with an inner wall defining a cavity; and stacking roller chains placed within the cavity. To prevent the two rollers of the stacking roller chain from directly contacting the inner wall and causing wear or excessive friction, a support member can be provided between the two rollers and the inner wall. The support member is made of a wear-resistant material with a low coefficient of friction. Utility Model Content

[0004] The purpose of this invention is to provide an improved stacking roller chain conveyor, which facilitates the assembly and disassembly of the stacking roller chain conveyor, especially the support components.

[0005] Therefore, according to one aspect of the present invention, a stacking roller chain conveying device is provided, comprising: a track body having: a base; and an arm extending vertically upward from the base to define a cavity together with the base, the cavity defining an upward notch; a cover detachably mounted to the arm, the cover covering a portion of the upward notch to form an opening having a lateral dimension, and the base defining a groove located within the cavity; a support inserted into the groove; and a stacking roller chain placed in the cavity, comprising rollers and rollers located on both lateral sides of the rollers, the rollers being supported by the support, wherein the lateral dimension of the opening is smaller than the lateral dimension of the stacking roller chain, and, viewed in a lateral section, the circumferential edge of the roller extends from the opening on its upper side in the vertical direction.

[0006] Optionally, the cover includes a cap and a protruding edge extending from the cap, the cap snapping into the arm such that the protruding edge covers a cavity near the arm, thereby forming an opening.

[0007] Optionally, the arm includes a head and a neck connected to each other, the lateral dimension of the head being greater than that of the neck, and the inner wall of the cap defining a receiving chamber and a receiving channel communicating with each other, the receiving chamber being configured to receive the head and the receiving channel being configured to receive the neck, such that the cap snaps into the arm.

[0008] Optionally, the head has an inclined surface formed on at least one of its lateral sides, and a mating inclined surface is formed on at least one corresponding side of the receiving chamber defined by the inner wall of the cap. The angle of the inclined surface relative to the vertical direction is greater than the angle of the mating inclined surface relative to the vertical direction, so that when the receiving chamber receives the head, the mating inclined surface is abutted by the inclined surface and elastically deformed.

[0009] Optionally, the tip of the protruding edge forming an opening is close to the upper side of the circumferential edge of the roller and the roller and has an inclined surface facing the cavity, so that the tip of the protruding edge is reduced in size in the vertical direction.

[0010] Optionally, the arm includes a first arm and a second arm extending vertically upward from the lateral sides of the base, respectively, and the cover includes a first cover detachably mounted to the first arm and / or a second cover detachably mounted to the second arm.

[0011] Optionally, the vertical dimension of the first arm is greater than the vertical dimension of the second arm.

[0012] Optionally, the groove includes a first groove and a second groove, and the support includes a first support inserted into the first groove and a second support inserted into the second groove.

[0013] Optionally, the support includes a tail and a body connected to each other, the tail being configured to insert into a groove such that the body is positioned in the cavity and protrudes vertically upward relative to the base to support the roller.

[0014] Optionally, the tail and the groove have a curvature that bends toward the arm.

[0015] Alternatively, the track body is made of a single piece of metal profile, and the cover is made of plastic.

[0016] The stacking roller chain conveyor proposed in this utility model can provide a wider space for the insertion of the support member by means of the lateral dimension of the cavity before the cover is assembled onto the arm. Therefore, the support member can be manipulated with greater freedom of tools during insertion and possible subsequent disassembly and replacement. It is even possible to complete the insertion, disassembly and replacement of the support member with the operator's hands without tools. This is significantly better than inserting the support member with tools when the cover is not removable, and better than directly disassembling and replacing the support member in the longitudinal direction.

[0017] Other features and advantages of the present invention will become clear from the following detailed description of exemplary embodiments of the present invention with reference to the accompanying drawings. Attached Figure Description

[0028] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0029] Technologies and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such technologies and equipment should be considered part of the specification.

[0030] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0032] A stacking roller chain conveyor is composed of multiple stacking roller chain conveyor units (hereinafter referred to as conveyor units) assembled together. (See reference...) Figure 1 The X-axis of the orthogonal coordinate system indicates the longitudinal direction of the conveying device 20, the Y-axis indicates the transverse direction, and the Z-axis indicates the vertical direction. Here, the conveying device 20 mainly includes a track body 22, a stacking roller chain 10, covers such as a first cover 24 and a second cover 26, and supports such as a first support 28 and a second support 30. Furthermore, this is merely for illustrative purposes and does not reflect the actual situation. Figure 1 In the middle, the track body 22, the stacked roller chain 10, the first cover 24 and the second cover 26, and the first support 28 and the second support 30 have different dimensions (i.e., length) in the longitudinal direction.

[0033] The track body 22 may be made of a single metal profile, such as an aluminum profile, and the track body 22 includes a first part 22a and a second part 22b that are connected to each other, for example, by a connecting part 22c located between the first part 22a and the second part 22b. Alternatively, the first part 22a and the second part 22b may be directly connected together.

[0034] like Figures 2 to 4 As shown, the stacked roller chain 10 includes a series of links linked together to form a circular chain. Figure 2 (Only a portion of the chain links are shown in the diagram). Each chain link typically includes a pin 11, a sleeve 12, a roller 13, two rollers 14 located on either side of the roller 13, an outer chain plate 15, and an inner chain plate 16. The outer chain plate 15 is riveted to the pin 11. The inner chain plate 16, sleeve 12, and rollers 14 are rotatably mounted on the pin 11, and the roller 13 is rotatably mounted on the sleeve 12. The diameter of the roller 13 is larger than the diameter of the roller 14, and when an item is placed on the stacking roller chain 10, the bottom of the item contacts the roller 13. Therefore, as the item supported on the roller 13 moves forward with the stacking roller chain 10, if the item is blocked in front, sliding occurs between the roller 13 and the sleeve 12, keeping the item in its current position, thus achieving stacking. When the obstruction is removed, the item can continue to be conveyed forward.

[0035] Continue to refer to Figures 2 to 4 The outer link plate 15 and the inner link plate 16 are adjacent to each other, the sleeve 12 is disposed between a pair of inner link plates 16, and the two rollers 14 are respectively disposed at both ends of the pin 11. Additionally, in Figures 2 to 4 In this embodiment, not all sleeves 12 are fitted with rollers 13; rather, one roller 13 is provided on every other sleeve 12. However, it should be noted that the conveying device 20 of this application may adopt a structure different from the stacked roller chain 10 described and shown above, and may include stacked roller chains 10 with various structures known in the art. For example, rollers 13 may be provided on all sleeves 12, or more pairs of chain plates, rollers 14, and sleeves may be provided.

[0036] like Figure 5 and Figure 6 As shown, the first portion 22a includes: a base 32; and arms, such as a first arm 34 and a second arm 36, extending substantially vertically upward from both lateral sides of the base 32. A first cover 24 is detachably fitted to the first arm 34, and a second cover 26 is detachably fitted to the second arm 36. The base 32, the first arm 34, and the second arm 36 together define a first cavity 38, wherein the first cavity 38 defines an upward notch, and the first cover 24 and the second cover 26 together cover a portion of the upward notch such that the remaining portion of the upward notch forms an opening 40, the lateral dimension H1 of the opening 40 being smaller than the lateral dimension H2 of the first cavity 38, or in other words, the lateral dimension H1 of the opening 40 being smaller than the lateral dimension H3 of the stacked roller chain 10, and the base 32 defines a groove, such as a first groove 42 and a second groove 44, located within the first cavity 38 on the lower side of the first portion 22a in the vertical direction.

[0037] The first support member 28 includes a first tail portion 28a and a first body 28b connected to each other. The second support member 30 includes a second tail portion 30a and a second body 30b connected to each other. The first tail portion 28a is configured to insert into a first groove 42, and the second tail portion 30a is configured to insert into a second groove 44, so that the first body 28b and the second body 30b can be positioned in the first cavity 38 and protrude vertically upward relative to the base 32 to support the two rollers 14 of the stacked roller chain 10 placed in the first cavity 38, respectively. At the same time, in a transverse section, the circumferential edge of the roller 13 protrudes from the opening 40 on the upper side in the vertical direction, thereby supporting the conveyed items. The transverse dimension H1 of the opening 40 is larger than the transverse dimension of the roller 13, so that the upper part of the roller 13 can protrude from the opening 40. The first support member 28 and the second support member 30 are disposed between the two rollers 14 and the base 32 to avoid the two rollers 14 directly contacting the base 32 and causing wear or excessive friction.

[0038] For example, the shape of the first tail 28a matches the shape of the first groove 42, and the shape of the second tail 30a matches the shape of the second groove 44, wherein the first tail 28a and the first groove 42 have curvatures that bend toward the first arm 34, and the second tail 30a and the second groove 44 have curvatures that bend toward the second arm 36, so as to facilitate the insertion of the first support 28 and the second support 30.

[0039] Furthermore, the second part 22b is provided with a second cavity 46, and the inner wall defining the second cavity 46 is further formed with a first protrusion 48 and a second protrusion 50 that are opposite to each other and are used to support the two rollers 14 of the stacked roller chain 10, respectively. Similarly, the first protrusion 48 and the second protrusion 50 can be respectively fitted onto the third support and the fourth support to avoid direct contact between the first protrusion 48 and the second protrusion 50 and the two rollers 14, which would cause wear or excessive friction.

[0040] It is understandable that each support component is made of a wear-resistant material with a low coefficient of friction.

[0041] Here, the vertical dimension (i.e., height) of the first arm 34 is greater than that of the second arm 36 in the vertical direction, so as to limit the conveying range of the items and prevent the items from falling from the lateral side of the conveying device 20.

[0042] Optionally, such as Figure 7 As shown, the first arm 34 includes a first head 34a and a first neck 34b connected to each other. For example, the lateral dimension L1 of the first head 34a is greater than the lateral dimension L2 of the first neck 34b. Correspondingly, the first cover 24 includes a first cap portion 52, which includes a first cap top 52a and a first cap brim 52b and a second cap brim 52c extending substantially vertically downward from the lateral sides of the first cap top 52a, respectively. The tips of the first cap brim 52b and the second cap brim 52c, away from the first cap top 52a, are laterally enlarged. Thus, the inner walls of the first cap top 52a, the first cap brim 52b, and the second cap brim 52c together define a first receiving chamber 54 and a first receiving channel 56 that communicate with each other, and the lateral dimension L3 of the first receiving chamber 54 is greater than the lateral dimension L4 of the first receiving channel 56. The first receiving chamber 54 is configured to receive the first head 34a, and the first receiving channel 56 is configured to receive the first neck 34b, such that the first arm 34 is snapped into engagement with the first cap portion 52 of the first cover 24.

[0043] For example, the first head 34a forms a first inclined surface 34a1 on at least one of its lateral sides, for example, the angle of the first inclined surface 34a1 relative to the vertical direction is 5 degrees. Correspondingly, the inner wall of at least one of the first brim 52b and the second brim 52c forms a first mating inclined surface 53 on a portion defining the first receiving chamber 54, for example, the angle of the first mating inclined surface 53 relative to the vertical direction is 4 degrees. Thus, the angle of the first inclined surface 34a1 relative to the vertical direction is greater than the angle of the first mating inclined surface 53 relative to the vertical direction. When the first receiving chamber 54 receives the first head 34a, the first mating inclined surface 53 is abutted against by the first inclined surface 34a1 and slightly elastically deformed to help securely snap the first cap portion 52 of the first cover 24 to the first head 34a of the first arm 34.

[0044] The first cover 24 also includes a first protruding edge 58 extending laterally from the tip of the second brim 52c, away from the first cap top 52a. The first protruding edge 58 shields the first recess 38 near the first arm 34 to shield as much of the stacked roller chain 10 as possible, except for the rollers 13, i.e., to enclose the environment of the first recess 38 as much as possible, thereby preventing the rollers 14 and sleeves 12 of the stacked roller chain 10 from contacting the object and causing scratches, etc. However, if the first protruding edge 58 is too close to the rest of the stacked roller chain 10, such as the rollers 14, the stacked roller chain 10 may interfere with the first cover 24 or even lift it up during movement due to slippage. Optionally, the tip of the first protrusion 58, which is away from the second cap 52c and defines the opening 40, is close to the upper side of the circumferential edge of the roller 13 and one of the two rollers 14 and has a first inclined surface 58a facing the first cavity 38, so that the vertical dimension (i.e., thickness) of the tip of the first protrusion 58 is reduced, thus making room for the stacked roller chain 10 placed in the first cavity 38.

[0045] Similarly, such as Figure 8As shown, the second arm 36 includes a second head 36a and a second neck 36b connected to each other. For example, the lateral dimension L5 of the second head 36a is greater than the lateral dimension L6 of the second neck 36b. Correspondingly, the second cover 26 includes a second cap portion 60, which includes a second cap top 60a and a third cap brim 60b and a fourth cap brim 60c extending substantially vertically downward from the lateral sides of the second cap top 60a, respectively. The tips of the third cap brim 60b and the fourth cap brim 60c, away from the second cap top 60a, are laterally enlarged, thereby defining a second receiving chamber 62 and a second receiving channel 64 that communicate with each other, and the lateral dimension L7 of the second receiving chamber 62 is greater than the lateral dimension L8 of the second receiving channel 64. The second receiving chamber 62 is configured to receive the second head 36a, and the second receiving channel 64 is configured to receive the second neck 36b, such that the second arm 36 is snapped into contact with the second cap 60 of the second cover 26.

[0046] For example, the second head 36a has a second inclined surface 36a1 formed on at least one of its lateral sides. Correspondingly, the inner wall of at least one of the third brim 60b and the fourth brim 60c forms a second mating inclined surface 66 on a portion defining the second receiving chamber 62. The angle of the second inclined surface 36a1 relative to the vertical direction is greater than the angle of the second mating inclined surface 66 relative to the vertical direction. Thus, when the second receiving chamber 62 receives the second head 36a, the second mating inclined surface 66 is slightly elastically deformed by the second inclined surface 36a1 to help securely snap the second cap portion 60 of the second cover 26 to the second head 36a of the second arm 36.

[0047] The second cover 26 also includes a second protruding edge 68 extending laterally from one lateral end of the second cap 60a near the first recess 38. The second protruding edge 68 covers the first recess 38 near the second arm 36 to cover as much of the stacked roller chain 10 as possible, excluding the rollers 13. The tip of the second protruding edge 68, away from the second cap 60a and defining the opening 40, is close to the upper side of the circumferential edge of the roller 13 and the other of the two rollers 14 and has a second bevel surface 68a facing the first recess 38, such that the tip of the second protruding edge 68 is reduced in size in the vertical direction, creating space clearance for the stacked roller chain 10 placed in the first recess 38.

[0048] Here, the first cover 24 and the second cover 26 can be made of a material different from that of the track body 22. For example, the first cover 24 and the second cover 26 can be made of plastic so that the first cover 24 and the second cover 26 have a certain degree of elasticity and are easy to assemble and disassemble.

[0049] During the assembly of the conveying device 20, which is particularly related to the first part 22a, it is possible to first place, for example, Figure 5 The first support member 28, in the first orientation shown, is placed into the first recess 38 such that the first tail 28a is aligned with the first groove 42. Then, following the curvature of the first tail 28a and the first groove 42 towards the first arm 34, the first support member 28 is fully inserted into the first groove 42, so that the first support member 28 is positioned as shown in the diagram. Figure 6 The second orientation is shown, where the first orientation is perpendicular to the second orientation. Then, the insertion of the second support member 30 is completed in a similar manner. Here, since the lateral dimension H2 of the first cavity 38 is larger than the lateral dimension H1 of the opening 40, a wider space is provided for the insertion of the first support member 28 and the second support member 30. Therefore, in the insertion of the first support member 28 and the second support member 30, and in possible subsequent disassembly and replacement, tools can be used to manipulate the first support member 28 and the second support member 30 with greater freedom, or even without tools, the insertion, disassembly, and replacement of the first support member 28 and the second support member 30 can be completed solely by the operator's hands. That is, the lateral dimension H2 of the first cavity 38 allows the operator's hands to pass through. Then, the stacking roller chain 10 can be placed in the first cavity 38 so that the two rollers 14 of the stacking roller chain 10 are supported by the first support member 28 and the second support member 30 respectively and can rotate relative to the first support member 28 and the second support member 30. Finally, the first cover 24 can be assembled onto the first arm 34, and the second cover 26 can be assembled onto the second arm 36 to form as shown. Figure 9 The conveying device 20 shown.

[0050] It is understood that although the illustrated embodiment provides a removable first cover 24 and a second cover 26, other embodiments may also have only one removable cover. For example, only a removable first cover 24 may be provided, i.e., the first cover 24 is detachably mounted to the first arm 34 above the second arm 36, and the first cover 24, i.e., the first protrusion 58, covers a portion of the upward notch to form the opening 40. As described above, by removing the first cover 24 from the first arm 34, more space can be provided for the insertion of the first support 28 and the second support 30, and since the first arm 34 and the first cover 24 mounted on the first arm 34 may experience more wear in the process of restricting the transport range of the items (because the second cap 52c is the limiting surface that rubs against the tray), the first cover 24 can be replaced at any time based on the condition of wear. Optionally, since the use of the second cover 26 is eliminated, the second arm 36 may have, for example, a laterally protruding protrusion integrally integrated therewith to cover the first cavity 38 near the second arm 36.

[0051] The assembly process of the conveying device 20 provided by this utility model is significantly better than inserting the first support member 28 and the second support member 30 by tools when the first cover member 24 and the second cover member 26 are not removable, and it is also better than directly disassembling and replacing the first support member 28 and the second support member 30 in the longitudinal direction.

[0052] While specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
