Description

[Technical Field]

[0001] The present invention relates to a conveyor roller used in a conveyor system, and also to a conveyor system and an inclined conveyor system using the conveyor roller. [Background technology]

[0002] One type of conveyor device is a roller conveyor device, which has conveying rollers arranged in parallel between parallel frames. The roller conveyor device rotates the conveying rollers by power, and urges and moves the objects on the conveying rollers. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2018-135180 Summary of the Invention [Problem to be solved by the invention]

[0004] The conventional conveying roller is made of a metal tube, and the conveying portion is moved by rotating the metal tube. The conveyor rollers of the conventional technology are made of metal and have a hard surface. Therefore, there is a concern that the conveyed object may be damaged when it is inserted. In addition, the conveyed object may collide with the conveyor roller, generating noise.

[0005] In particular, when the conveyor device is used in an inclined position, there is a concern that noise may be generated and the objects being conveyed may be damaged. For example, there may be a case where there is a conveyor line on an upper floor and another on a lower floor, and a conveyor device is installed in an inclined position between the upper and lower floors. For convenience of explanation, a conveyor device installed in an inclined position will be referred to as an inclined conveyor device. For example, when moving an object from an upper floor to a lower floor, the conveyor line on the upper floor carries the object to the upper end of the inclined conveyor device, and then the inclined conveyor device is driven to lower the object onto the conveyor line on the lower floor.

[0006] Here, the conveying surface of the inclined conveyor is inclined, while the conveying surface of the conveyor line installed on the lower floor is horizontal. Therefore, an angle is generated between the conveying surface of the inclined conveyor and the delivery surface of the conveyor line on the lower floor, and when the conveying section is handed over from the inclined conveyor to the conveyor line on the lower floor, the corner of the conveyed object hits the delivery surface of the conveyor line on the lower floor. As a result, noise may be generated and the transported object may be damaged.

[0007] The present invention (related invention) solves the above-mentioned problems of the prior art, and aims to provide a conveying roller, conveyor device, and inclined conveyor that absorbs the impact of collisions and is less likely to generate collision noise or damage the transported object. An object of the present invention is to provide a conveying roller that can increase the chance of holding any part of a conveyed object. [Means for solving the problem]

[0008] An aspect (related invention) for solving the above-mentioned problem is a conveying roller that comes into contact with a conveyed object and moves the object, characterized in that the conveying roller has a core member and a plurality of wing-like pieces that are elastically deformable and are arranged around the core member.

[0009] The conveying roller of this aspect has a core member provided with a plurality of vane-like pieces, and the vane-like pieces rotate to move the conveyed object. The blades are elastically deformable, so they easily deform when an object collides with them, cushioning the impact of the collision. This reduces noise and damage to the conveying section.

[0010] In the above-described aspect, it is desirable that the vane-like piece be a thin plate, one end of which is joined to the core member, and the other end of which is a free end.

[0011] According to this embodiment, the blade-like pieces have high deformability and have a strong effect of cushioning the impact of a collision.

[0012] In the above-mentioned aspect, it is desirable that the wing-like piece has a curved cross-sectional shape and that the free end side of the wing-like piece is located in a position where it overlaps with an adjacent wing-like piece and / or where it covers part of an adjacent wing-like piece.

[0013] According to this aspect, the blade-shaped pieces are distributed without gaps in the circumferential direction, so that the impact on the transported object is small.

[0014] In each of the above-described aspects, it is desirable that the vanes are arranged at regular intervals around the core member, and that there are regions in the axial direction where the vanes are arranged out of phase with one another.

[0015] According to this aspect, the chances of holding any part of the transported object by any of the blades are increased.

[0016] In each of the above-described aspects, it is desirable that the roller is constituted by a plurality of roller pieces, and that the roller pieces have the above-described blade-shaped pieces provided on the shaft portion.

[0017] According to this aspect, the overall length of the conveying roller can be changed by changing the number of roller pieces, and conveying rollers of multiple lengths can be manufactured using a small number of different parts. Therefore, the conveying roller of this aspect has high interchangeability of parts.

[0018] In the above-mentioned aspect, it is desirable that the roller piece has an engagement portion that engages with and aligns with an adjacent roller piece, and that by matching the engagement portions, the phase of the arrangement of the wing-shaped pieces of the adjacent roller pieces is shifted.

[0019] According to this aspect, the chances of holding any part of the transported object by any of the blades are increased.

[0020] Another aspect for solving a similar problem is a conveying roller that comes into contact with a conveyed object and moves the object, and is characterized in that the conveying roller has a core member and a deformation portion that is elastically deformable and is provided around the core member.

[0021] The conveying roller of this aspect has a deformed portion provided on the core member, and the deformed portion rotates to move the conveyed object. The deformable portion easily deforms when an object collides with it, cushioning the impact of the collision. Therefore, even if an object collides with it, the conveying portion is unlikely to be damaged.

[0022] In the above-described aspect, it is preferable that the roller is constituted by a plurality of roller pieces, and that the roller pieces have a deformed portion provided on the shaft portion.

[0023] According to this aspect, the overall length of the conveying roller can be changed by changing the number of roller pieces, and conveying rollers of multiple lengths can be manufactured using a small number of different parts. Therefore, the conveying roller of this aspect has high interchangeability of parts.

[0024] In each of the above-described aspects, it is desirable that an urging region and a void region exist in the axial direction, the urging region being a region that contributes to the transport of the transported object, and the void region being a region that does not contribute to the transport of the transported object.

[0025] According to this aspect, when the transport rollers are arranged in parallel, the distance between the axes of the transport rollers can be shortened.

[0026] In each of the above-mentioned aspects, it is desirable that the roller piece is composed of a plurality of roller pieces, each of which has an urging area and a gap area, the urging area being an area that contributes to the transport of the transported object, and the gap area being an area that does not contribute to the transport of the transported object.

[0027] According to this aspect, when the transport rollers are arranged in parallel, the distance between the axes of the transport rollers can be shortened.

[0028] In one aspect of the conveyor device, the conveying rollers according to any one of the above-described embodiments are arranged in parallel.

[0029] According to this aspect, when an object collides with the transport roller, the transport roller easily deforms, cushioning the impact of the collision. Therefore, even if an object collides with the transport roller, the transport section is unlikely to be damaged.

[0030] In the above-described aspect, it is desirable that the conveying rollers have a large diameter portion and a small diameter portion, the large diameter portion of a specific conveying roller is located at a position corresponding to the small diameter portion of an adjacent conveying roller, the small diameter portion of a specific conveying roller is located at a position corresponding to the large diameter portion of an adjacent conveying roller, and the axis-to-axis distance between the adjacent conveying rollers is shorter than the diameter of the large diameter portion.

[0031] According to this aspect, the transport rollers can be arranged closely together, which increases the chances of the transported object coming into contact with the transport rollers, making it less likely for the transported object to rattle.

[0032] The inclined conveyor is an inclined conveyor device that is installed in an inclined position, and has a middle region and an upper end region and / or a lower end region, and the upper end region and / or the lower end region The present invention is characterized in that any one of the conveyor devices described above is provided.

[0033] According to this aspect, the impact on the transported object is small.

[0034] Another mode for solving the same problem is a conveyor device in which transport rollers are arranged in parallel, the transport rollers having a large diameter portion and a small diameter portion, the large diameter portion of a specific transport roller being located at a position corresponding to the small diameter portion of an adjacent transport roller, the small diameter portion of a specific transport roller being located at a position corresponding to the large diameter portion of an adjacent transport roller, and the distance between the axes of adjacent transport rollers being shorter than the diameter of the large diameter portions.

[0035] According to this aspect, the conveying rollers can be arranged closely together, which increases the chances of the conveyed object coming into contact with the conveying rollers and reduces the chances of the conveyed object rattling, thereby reducing the impact on the conveyed object. An embodiment for solving the above-mentioned problem is a conveyor device in which conveying rollers are arranged in parallel, and the conveying rollers are rotated by power to force and move the objects being conveyed on the conveying rollers, wherein the conveying rollers have a large diameter portion and a small diameter portion, the large diameter portion of a specific conveying roller is located at a position corresponding to the small diameter portion of an adjacent conveying roller, the small diameter portion of a specific conveying roller is located at a position corresponding to the large diameter portion of an adjacent conveying roller, and the distance between the axes of adjacent conveying rollers is shorter than the diameter of the large diameter portions.

[0038] Hereinafter, an embodiment of the present invention will be described. The transport roller 1 of this embodiment is a member that constitutes the transport surface of conveyor devices 50 and 51 as shown in FIGS. As shown in FIG. 1, the conveying roller 1 has pulleys 2 at both ends and a conveying portion 3 in the middle. As shown in FIGS. 1 and 2, the conveying section 3 is made up of a plurality of roller pieces 5 connected in series, with a rotation core 6 inserted through each roller piece 5.

[0039] The roller pieces 5 are molded from resin. As shown in Figures 3 and 4, the roller pieces 5 have a short rotation core component (shaft) 10, and a deformed portion is provided around a portion of the longitudinal direction of the roller pieces 5. In this embodiment, the deformed portion is a wing-shaped piece 11, and multiple wing-shaped pieces 11 are provided. The rotary core constituent part 10 (shaft part) is a short tube and is provided with a through hole 12. In this embodiment, the cross-sectional shape of the through hole 12 is hexagonal. The cross-sectional shape of the through hole 12 is not limited to a hexagon, and it is sufficient if it has a portion that engages with the rotary core 6.

[0040] Each of the blades 11 is thin and curved. The blades 11 employed in this embodiment have an arc-shaped cross section. The blades 11 are arcs of approximately 180 degrees. The arc angle of the blades 11 is preferably 90 degrees or more. The arc angle of the blades 11 is preferably 270 degrees or less. It is recommended that the diameter of the arc of the blade-like piece 11 be 50 to 200 percent of the diameter of the rotating core component 10 (shaft portion). In this embodiment, the diameter of the arc of the blade-like piece 11 is equal to the diameter of the rotation core constituent part 10 .

[0041] One end of each of the blades 11 is connected to the rotary core component (shaft) 10, and the other end is a free end. Therefore, the blades 11 are attached in a cantilevered manner to the rotary core component 10. As a result, the blades 11 easily undergo elastic deformation when subjected to an external force. In other words, when a load is applied from the outside, the blades 11 elastically deform, causing the free end to bend toward the rotary core component 10. The vane-like pieces 11 are arranged radially with respect to the rotary core constituent part 10. The vane-like pieces 11 are also arranged densely around the rotary core constituent part 10. That is, when focusing on the base end of each vane-like piece 11, the gap between adjacent vane-like pieces 11 is extremely small.

[0042] The blade-like pieces 11 are provided in an orientation such that the side facing the rotation core component 10 is concave. 3 and 4, the free end side of the vane-like piece 11 covers the area from the base end to the central region of the adjacent vane-like piece 11. In this embodiment, when an object is placed near the free end of one vane-like piece 11, the vane-like piece 11 bends and hits the vane-like piece 11 below, allowing the vane-like piece 11 to also bear the load of the object. This prevents the vane-like pieces 11 from being excessively deformed. In this embodiment, the free ends of the blades 11 are spaced apart from adjacent blades 11, but the free ends of the blades 11 may also be in contact with adjacent blades 11.

[0043] The region where the vane-shaped pieces 11 are provided is a portion near one end of the rotation core constituent part (shaft part) 10. The length l of the region where the vane-shaped pieces 11 are provided is half or less of the total length L of the rotation core constituent part 10. The length l of the region where the blade-like pieces 11 are provided is preferably about 30 to 45 percent of the total length L of the rotation core component 10 .

[0044] 3 and 4, engaging portions 15 and 16 are provided on both ends of the rotary core forming portion 10. The engagement portion 15 on the front side (the side of the blade-like pieces 11) is a protrusion as shown in FIG. 3, and the engagement portion 16 on the back side (the side of the blade-like pieces 11) is a recess as shown in FIG. The angles of the engagement portions 15 and 16 relative to the rotation core constituent portion 10 are different as shown in FIGS. In this embodiment, the engagement portion 15 on the front side (the side of the blade 11) is located at the base of the blade 11 as shown in Figure 3, while the engagement portion 16 on the back side (the side of the blade 11) is located between the bases of the two blades 11. Therefore, when the engaging portions 15, 16 are brought together to join the two roller pieces 5, the positions of the blade-like pieces 11 are shifted as shown in FIG. That is, the engaging portions 15 and 16 are for positioning, and by matching the engaging portions 15 and 16, the phases of the arrangement of the vane-like pieces 11 of the adjacent roller pieces 5 are shifted.

[0045] As shown in Figures 1 and 2, the conveying roller 1 is made up of multiple roller pieces 5 joined together, with the rotating core components 10 connected to form a series of core members 20, and a hexagonal rotating core 6 inserted into the through hole 12. Pulleys 2 are attached to both ends of the rotating core 6 .

[0046] When the conveying section 3 of the conveying roller 1 is viewed generally, regions where the core member 20 is provided with the vanes 11 and regions where the vanes 11 are not present are alternately present. The area of ​​the core member 20 where the vane-like pieces 11 are provided is a large diameter portion 30 with a large apparent diameter, and the area where the vane-like pieces 11 are not present is a small diameter portion 31 with a small apparent diameter. In the conveying roller 1 of this embodiment, large diameter portions 30 and small diameter portions 31 are alternately arranged in the axial direction. The large diameter portion 30 is a region that comes into contact with the object and is a biasing region that contributes to the transport of the object, while the small diameter portion 31 is a gap region that does not come into contact with the object and does not contribute to the transport of the object.

[0047] Furthermore, the conveying roller 1 has a plurality of large diameter portions (urging regions) 30, among which some of the large diameter portions have misaligned blades 11.

[0048] FIG. 6 shows an inclined conveyor device 40 according to an embodiment of the present invention. The inclined conveyor device 40 is divided into three regions as shown in FIG. That is, the inclined conveyor device 40 is divided into an upper end region 60, an inclined region 61 and a lower end region 62. In this embodiment, the upper end region 60, the inclined region 61, and the lower end region 62 are each a separate conveyor device, and the conveying roller 1 of this embodiment is used in the upper end region 60 and the lower end region 62.

[0049] In the inclined conveyor device 40 of this embodiment, the upper conveyor device 50 constituting the upper end region 60 and the lower conveyor device 51 constituting the lower end region 62 both have curved conveying surfaces. Specifically, the upper conveyor device 50 has the conveying rollers 1 arranged so that the conveying surface is convex upward. The lower conveyor device 51 has the conveying rollers 1 arranged so that the conveying surface is convex upward.

[0050] Taking the lower conveyor device 51 as an example, the lower conveyor device 51 has a motorized roller 57 and a plurality of transport rollers 1 arranged in parallel on frames 55 and 56 arranged in parallel. As shown in FIG. 7(b), the frames 55 and 56 are curved in a downward convex shape. A motorized roller 57 is attached to one end of the frames 55 and 56 . In other areas, a plurality of conveying rollers 1 are arranged in parallel. Specifically, a plurality of conveying rollers 1 are attached in parallel.

[0051] In this embodiment, the positions of the large diameter portions 30 and the small diameter portions 31 of the adjacent conveying rollers 1 are offset from each other. That is, when focusing on a specific conveying roller 1, the position of the large diameter portion 30 of the specific conveying roller 1 corresponds to the position of the small diameter portion 31 of the adjacent conveying roller 1, and the position of the small diameter portion 31 of the specific conveying roller 1 corresponds to the position of the large diameter portion 30 of the adjacent conveying roller 1.

[0052] Further, the distance W between the axes of the adjacent conveying rollers 1 is shorter than the diameter of the large diameter portion 30. Therefore, the large diameter portion 30 and the small diameter portion 31 of the adjacent conveying rollers 1 are in a mating state. In other words, when focusing on a specific conveying roller 1, the large diameter portions 30 of adjacent conveying rollers 1 are sandwiched between the large diameter portions 30 of the specific conveying roller 1, and the outer contours of the large diameter portions 30 of the adjacent conveying rollers 1 are approaching the core member 20 of the specific conveying roller 1. Therefore, as shown in Fig. 7(a), the lower conveyor device 51 has the blades 11 arranged densely, and the entire surface of the lower conveyor device 51 functions as a conveying surface. In other words, the entire surface of the lower conveyor device 51 is an urging area.

[0053] In this embodiment, each of the conveying rollers 1 is driven by a motorized roller 57 as a power source. That is, the motorized roller 57 is provided with a drive pulley 35, and a belt 36 is suspended between the drive pulley 35 and one pulley 2 of the adjacent first conveying roller 1. A belt 36 is suspended between the other pulley 2 of the first conveying roller 1 and the pulley 2 of the adjacent second conveying roller 1. In this way, the belt 36 is successively suspended between the adjacent conveying rollers 1, and by rotating the motorized roller 57, all of the conveying rollers 1 are rotated. In this embodiment, the conveying roller 1 rotates in a direction in which the base end side of the vane-like piece 11 is in the front and the free end side is in the rear. The orientation (winding direction) of the vane-like piece 11 and the rotation direction of the conveying roller 1 are not limited and may be reversed. Furthermore, vane-like pieces 11 with different winding directions may be mixed.

[0054] Assuming that an object is to be lowered from an upper floor to a lower floor, the inclined conveyor device 40 has an upper conveyor device 50 whose conveying surface is curved in an upward convex shape, and the conveying surface at the connection portion to the inclined region 61 has a gentle curve, so that the object can smoothly move to the inclined region 61. In addition, in the inclined conveyor device 40 used in this embodiment, the conveying surface of the lower conveyor device 51 is curved in a downward convex shape, and the conveying surface at the connection portion from the inclined region 61 has a gentle curve, so that the transported object can smoothly move from the inclined region 61 to the lower conveyor device 51.

[0055] 7(a), the lower conveyor device 51 has the vane-like pieces 11 arranged closely, and the entire surface of the lower conveyor device 51 functions as a conveying surface. Therefore, there are many opportunities for the conveyed object to come into contact with the conveying rollers 1, and the conveyed object is less likely to rattle when it is transferred from the inclined region 61 to the lower end region 62. In particular, in this embodiment, the conveying roller 1 has a plurality of large diameter portions (urging regions) 30, some of which have misaligned vane-like pieces 11. Therefore, when an object reaches the lower conveyor device 51 and comes into contact with one of the conveying rollers 1, the object is supported by one of the vane-like pieces 11. Therefore, when the object is transferred from the inclined region 61 to the lower end region 62, the object is less likely to rattle.

[0056] Furthermore, when an object is transferred from the inclined region 61 to the lower end region 62, if a corner of the object collides with the lower conveyor device 51, the blades 11 of the transport roller 1 deform to absorb the impact. That is, the blades 11 are curved and tightly surround the core member, so the corners of the transported object hit one of the blades 11. The blades 11 are attached in a cantilevered manner, so they are flexible and have high deformability. Therefore, when a corner of the transported object hits the lower conveyor device 51, the blades 11 of the transport roller 1 deform and absorb the impact. This means that the transported items are less likely to be damaged and there is also less noise generated.

[0057] In the embodiment described above, the motorized roller 57 is used as a power source to rotate the multiple conveying rollers 1, but the power source for the conveying rollers 1 is arbitrary. For example, a geared motor or the like may be used as the power source. Alternatively, the motorized roller 57 may be used as a core member, and blade-shaped pieces may be provided on the roller body of the motorized roller 57 to form a conveying roller.

[0058] In the embodiment described above, pulleys 2 are provided on both ends of the conveying roller 1, and a belt 36 is suspended between adjacent conveying rollers 1 to transmit power sequentially. However, multiple pulleys may be provided on one side of the conveying roller 1, and a belt 36 may be suspended between adjacent conveying rollers 1 to transmit power sequentially. In the embodiment described above, power is transmitted to each conveying roller 1 by the belt 36, but the power transmission mechanism is not limited to a belt. For example, gears or chains may be used.

[0059] In the embodiment described above, the rotating core 6 that engages with the through hole 12 of the rotating core component 10 (shaft portion) is inserted into the through hole 12, and the rotating core 6 is rotated by power to rotate the blade-shaped piece 11, but the rotating core component 10 (shaft portion) may be made freely rotatable relative to the shaft core, and the rotational force may be transmitted to the core member 20 formed by the rotating core component 10 (shaft portion).

[0060] The conveying roller 1 described above is configured by connecting in series a plurality of roller pieces 5. According to the structure of this embodiment, conveying rollers 1 of different lengths can be produced by increasing or decreasing the number of roller pieces 5, resulting in high interchangeability of parts.

[0061] The number of roller pieces 5 is preferably four or more. That is, in the conveyor devices 50 and 51 of this embodiment, the positions of the vane-shaped pieces 11 of adjacent roller pieces 5 are shifted, and the phases are different. In contrast, the positions of the vane-shaped pieces 11 of the roller pieces 5 located every other position are the same, and the roller pieces 5 are in the same phase. Therefore, if the number of roller pieces 5 is four or more, the conveyed object is simultaneously supported by the blade-like pieces 11 of a plurality of roller pieces 5. Therefore, the conveyed object is less likely to rattle. However, the present invention is not limited to this configuration, and the entire structure may be integrally molded.

[0062] In the above-described conveying roller 1, regions where the blade-like pieces 11 are provided on the core member 20 and regions where the blade-like pieces 11 are not present are present alternately. According to this configuration, when the conveyor is incorporated into a conveyor device, the distance between the axes of the conveyor rollers 1 can be shortened, and the urging areas that contribute to the conveyance of the object to be conveyed can be densely arranged. That is, the part that actually comes into contact with the transported object is the uppermost part of the urging area during rotation, which causes a gap between adjacent urging areas. In the conveyor devices 50 and 51 of this embodiment, the large diameter section 30 and the small diameter section 31 of the adjacent conveying rollers 1 are interlocked, and the parts that actually contribute to conveyance are arranged in a staggered pattern, so there are many opportunities for contact with the conveyed object, and the conveyed object is less likely to rattle. However, the present invention is not limited to this configuration, and the blade-like pieces 11 may be provided in the entire area of ​​the transport roller 1 in the axial direction.

[0063] The conveying rollers 1 employed in the conveyor devices 50 and 51 described above are each formed by connecting roller pieces 5 of the same shape, but conveying rollers using roller pieces 5 of different shapes may be mixed. For example, in a conveyor device 80 shown in FIG. 9, transport rollers 81 having a large proportion of large diameter portions (urging regions) 30 and transport rollers 82 having a small proportion of large diameter portions (urging regions) 30 are arranged alternately. In the conveyor device 80, the distance W between the axes of the adjacent transport rollers 81 and 82 is shorter than the diameter of the large diameter portion 30.

[0064] In the embodiment described above, the wing-like piece 11 is shown as an example of the deformed portion, but the shape of the deformed portion is not limited to a wing-like shape. FIG. 10 shows a modified example of the deformation portion. The deformation portion 43 employed in the roller piece 42 shown in Figure 10(a) is composed of linear wing-shaped pieces 45. The wing-shaped pieces 45 of the roller piece 42 are provided in the normal direction to the rotation core constituent part (shaft part) 10. The deformation portion 66 employed in the roller piece 65 shown in Figure 10(b) is composed of a linear wing-like piece 67. The wing-like piece 67 of the roller piece 65 is provided with a tangential component with respect to the rotation core constituent part (shaft part) 10. The deformed portion 71 employed in the roller piece 70 shown in FIG. 10(c) has a structure in which the free ends of all the blade-like pieces 72 are connected in an annular shape. The deforming portion 76 employed in the roller piece 75 shown in FIG. 10(d) is composed of a wing-shaped piece 78 having both ends connected together. [Explanation of symbols]
