Summary of the Invention

Problems to be Solved by the Invention

[0004] Conventional conveying rollers are composed of metal pipes, and the metal pipes are rotated to move the conveying part. Since conventional conveying rollers are made of metal, their surfaces are hard. Therefore, when a conveyed object is loaded, there is a concern that the conveyed object may be damaged. Also, when the conveyed object collides with the conveying roller, noise may occur.

[0005] In particular, when the conveyor device is used in an inclined posture, there is a concern that noise may occur or the conveyed object may be damaged. For example, there may be a conveyor line on the upper floor and also a conveyor line on the lower floor, and a conveyor device may be installed in an inclined posture between the upper floor and the lower floor. For convenience of explanation, a conveyor device installed in an inclined posture is referred to as an inclined conveyor device. For example, when moving a conveyed object from an upper floor to a lower floor, the conveyed object is transported to the end of the inclined conveyor device on the upper floor side by a conveyor line on the upper floor. Then, the inclined conveyor device is driven to lower the conveyed object onto the conveyor line on the lower floor.

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

[0007] The present invention solves the above-mentioned problems of the prior art, and an object thereof is to provide a conveying roller, a conveyor device, and an inclined conveyor that can reduce impacts such as collisions, are less likely to generate collision sounds, and are less likely to damage conveyed objects.

[0009] In the conveying roller of this aspect, a plurality of blade-like pieces are provided on the core member, and the conveyed object is moved by the rotation of the blade-like pieces. Since the blade-like pieces are elastically deformable, they easily deform when the conveyed object collides, reducing the impact of the collision. Therefore, even when the conveyed object collides, noise is less likely to be generated. Also, the conveying part is less likely to be damaged.

[0010] In the above aspect, it is desirable that the blade-like pieces are in a thin plate shape, one end side is joined to the core member, and the other end side is a free end.

[0011] According to this aspect, the deformability of the blade-like piece is high, and the effect of reducing the impact of collision is strong.

[0012] In the above-described aspect, it is desirable that the blade-like piece has a curved cross-sectional shape, and the free end side of the blade-like piece is at a position overlapping with an adjacent blade-like piece and / or a position covering a part of an adjacent blade piece.

[0013] According to this aspect, the blade-like pieces are distributed without gaps in the circumferential direction. Therefore, the impact on the conveyed object is small.

[0014] In each of the above-described aspects, it is desirable that the blade-like pieces are arranged at regular intervals around the core member, and there is a region where the phase of the arrangement of the blade-like pieces is shifted in the axial direction.

[0015] According to this aspect, the chance of holding any part of the conveyed object with any blade-like piece increases.

[0016] In each of the above-described aspects, it is desirable that the roller is composed of a plurality of roller pieces, and the blade-like piece is provided on the shaft portion of the roller piece.

[0017] According to this aspect, by changing the number of roller pieces, the overall length of the conveying roller can be changed, and conveying rollers of a plurality of lengths can be manufactured with a small number of types of parts. Therefore, the conveying roller of this aspect has high component compatibility.

[0018] In the above-described aspect, the roller piece has an engaging portion for engaging with and aligning with an adjacent roller piece, and it is desirable that by aligning the engaging portions, the phase of the arrangement of the blade-like pieces of the adjacent roller pieces is shifted.

[0019] According to this aspect, the chance of holding any part of the conveyed object with any blade-like piece increases.

[0020] Another aspect for solving the same problem is a conveying roller that contacts a conveyed object and moves the conveyed object, characterized in that it has a core member and a deformable portion, the deformable portion being elastically deformable and provided around the core member. A specific aspect for solving the same problem is rotated by power ru A conveying roller that biases and moves a conveyed object on the conveying roller, having a plurality of large-diameter portions and a plurality of small-diameter portions, with the large-diameter portions and small-diameter portions alternating in the axial direction, and the large-diameter portions characterized in that it has a core member and a deformable portion, the deformable portion being provided around the core member, and there being a cavity between the annular portion that actually contacts the conveyed object and the core member and the deformable portion being elastically deformable.

[0021] In the conveying roller of this aspect, a deformable portion is provided on the core member, and the conveyed object is moved by the rotation of the deformable portion. The deformable portion easily deforms when the conveyed object collides, reducing the impact of the collision. Therefore, even if the conveyed object collides, it is difficult to damage the conveying part.

[0022] In the above aspect, it is preferably composed of a plurality of roller pieces, and the roller pieces are provided with deformable portions on the shaft portions. Another aspect for solving the same problem is a conveying roller that is rotated by power, and in the conveying roller that biases and moves the conveyed material on the conveying roller, it has a large-diameter portion and a small-diameter portion.

There is a cavity between the annular portion that actually contacts the conveyed material and the core member, and it is elastically deformable. It is composed of a plurality of roller pieces, and the roller pieces are provided with deformation portions on the shaft portions. It is a conveying roller characterized by this.

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

[0024] In each of the above aspects, in the axial direction, there are a biasing region and a void region, the biasing region being a region that contributes to the conveyance of the conveyed object, and the void region being a region that does not contribute to the conveyance of the conveyed object.

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

[0026] In each of the above-described aspects, it is preferably composed of a plurality of roller pieces, and the roller pieces have a biasing region and a gap region. The biasing region is a region that contributes to the conveyance of the conveyed object, and the gap region is a region that does not contribute to the conveyance of the conveyed object.

[0028] An aspect of the conveyor device is characterized in that the conveying roller described in any of the above is arranged in parallel.

[0029] According to this aspect, when the conveyed object collides, the conveying roller is easily deformed, reducing the impact of the collision. Therefore, even if the conveyed object collides, the conveying part is less likely to be damaged.

The large-diameter portion of a specific conveying roller is at a position corresponding to the small-diameter portion of the adjacent conveying roller, and the small-diameter portion of the specific conveying roller is at a position corresponding to the large-diameter portion of the adjacent conveying roller. It is preferably that the axial distance between the adjacent conveying rollers is shorter than the diameter of the large-diameter portion.

[0031] According to this aspect, the conveying rollers can be arranged densely. Therefore, the conveyed object has more contact opportunities with the conveying rollers, and the conveyed object is less likely to rattle.

[0032] An aspect related to the inclined conveyor is an inclined conveyor device installed in an inclined posture, having an intermediate region, an upper end region, and / or a lower end region, and the upper end region and / or the lower end region is characterized in that the conveyor device described in any of the above is arranged.

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

[0034] Another aspect for solving the same problem is a conveyor device in which conveying rollers are arranged in parallel. The conveying rollers have a large-diameter portion and a small-diameter portion. The large-diameter portion of a specific conveying roller is at a position corresponding to the small-diameter portion of an adjacent conveying roller, and the small-diameter portion of the specific conveying roller is at a position corresponding to the large-diameter portion of the adjacent conveying roller. The axial distance between the adjacent conveying rollers is shorter than the diameter of the large-diameter portion. A specific aspect for solving the same problem is a conveyor device in which conveying rollers are arranged in parallel, the conveying rollers are rotated by power, and the conveyed material on the conveying rollers is biased and moved.

[0035] According to this aspect, the conveying rollers can be arranged densely.

Embodiments for Carrying out the Invention

[0038] Hereinafter, embodiments of the present invention will be described. The conveying roller 1 of the present embodiment is a member that constitutes the conveying surface of conveyor devices 50 and 51 as shown in Figs. 6 to 8. 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 portion 3 is formed by connecting a plurality of roller pieces 5 in series, and a rotating core 6 is inserted through each roller piece 5.

[0039] The roller piece 5 is formed of resin. As shown in Figs. 3 and 4, the roller piece 5 has a short rotating core component (shaft portion) 10, and a deformed portion is provided around a part of the longitudinal region thereof. The deformed portion of the present embodiment is a blade-shaped piece 11, and a plurality of the blade-shaped pieces 11 are provided. The rotating core component 10 (shaft portion) is a short tube, and a through hole 12 is provided. In the present 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 hexagonal, and it is sufficient if there is a portion that engages with the rotating core 6.

[0040] Each blade-like piece 11 is thin plate-shaped, curved, and in a curved shape. The blade-like piece 11 adopted in this embodiment has an arc-shaped cross-sectional shape. The blade-like piece 11 is an arc of about 180 degrees. The angle of the arc of the blade-like piece 11 is desirably 90 degrees or more. Also, the angle of the arc of the blade-like piece 11 is desirably 270 degrees or less. It is recommended that the diameter of the arc of the blade-like piece 11 be from 50 percent to 200 percent of the diameter of the rotation 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 component 10.

[0041] One end side of the blade-like piece 11 is connected to the rotation core component (shaft portion) 10, and the other end side is a free end. Therefore, the blade-like piece 11 is attached to the rotation core component 10 in a cantilever manner. For this reason, when the blade-like piece 11 receives an external force, it easily elastically deforms. That is, when receiving a load from the outside, it elastically deforms and the free end side bends toward the rotation core component 10 side. The blade-like pieces 11 are arranged radially with respect to the rotation core component 10. Also, the blade-like pieces 11 are arranged in a dense state around the rotation core component 10. That is, when paying attention to the base end portions of the respective blade-like pieces 11, the gap between adjacent blade-like pieces 11 is extremely small.

[0042] The blade-like piece 11 is provided in a posture where the rotation core component 10 side is concave. The free end side of the blade-like piece 11 covers the area from the base end of the adjacent blade-like piece 11 to the central region as shown in FIGS. 3 and 4. In this embodiment, when the conveyed object is placed near the free end of one blade-like piece 11, the blade-like piece 11 bends and hits the lower blade-like piece 11, and the lower blade-like piece 11 can also bear the load of the conveyed object. Therefore, excessive deformation of the blade-like piece 11 can be prevented. In this embodiment, the free end of the blade-like piece 11 is separated from the adjacent blade-like piece 11, but the free end of the blade-like piece 11 may be in contact with the adjacent blade-like piece 11.

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

[0044] Engagement portions 15 and 16 are provided at both ends of the rotary core component 10 as shown in FIGS. 3 and 4. The engagement portion 15 on the front side (the side of the blade-shaped pieces 11) is a protrusion as shown in FIG. 3, and the engagement portion 16 on the back side (the side of the blade-shaped pieces 11) is a recess as shown in FIG. 4. The angles of the engagement portions 15 and 16 with respect to the rotary core component 10 are different as shown in FIGS. 3 and 4. In the present embodiment, the engagement portion 15 on the front side (the side of the blade-shaped pieces 11) is at the base of the blade-shaped pieces 11 as shown in FIG. 3, while the engagement portion 16 on the back side (the side of the blade-shaped pieces 11) is between the bases of the two blade-shaped pieces 11. Therefore, when the two roller pieces 5 are coupled together with the engagement portions 15 and 16, the positions of the blade-shaped pieces 11 are displaced as shown in FIG. 5. That is, the engagement portions 15 and 16 are for alignment, and by aligning the engagement portions 15 and 16, the phases of the arrangements of the blade-shaped pieces 11 of the adjacent roller pieces 5 are displaced.

[0045] The conveying roller 1 is formed by coupling a plurality of roller pieces 5 as shown in FIGS. 1 and 2, communicating the rotary core components 10 to form a series of core members 20, and inserting a hexagonal rotary core 6 into the through hole 12. Also, pulleys 2 are attached to both ends of the rotary core 6.

[0046] Looking at the conveying portion 3 of the conveying roller 1, regions where the blade-shaped pieces 11 are provided on the core member 20 and regions where the blade-shaped pieces 11 do not exist alternate with each other. The region where the blade-shaped pieces 11 are provided on the core member 20 is a large-diameter portion 30 with an apparently large diameter, and the region where the blade-shaped pieces 11 do not exist is a small-diameter portion 31 with an apparently small diameter. In the conveying roller 1 of the present embodiment, the large-diameter portions 30 and the small-diameter portions 31 are alternately present in the axial direction. The large-diameter portion 30 is a portion that contacts the conveyed object and is a biasing region that contributes to the conveyance of the conveyed object. The small-diameter portion 31 is a gap region that does not contact the conveyed object and does not contribute to the conveyance of the conveyed object.

[0047] Also, the conveying roller 1 has a plurality of large-diameter portions (biasing regions) 30, and among them, those with the position of the blade-shaped pieces 11 shifted are mixed.

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

[0049] In the inclined conveyor device 40 of the present embodiment, the upper conveyor device 50 that constitutes the upper end region 60 and the lower conveyor device 51 that constitutes the lower end region 62 both have a curved conveying surface. Specifically, in the upper conveyor device 50, the conveying rollers 1 are arranged such that the conveying surface is convex upward. In the lower conveyor device 51, the conveying rollers 1 are arranged such that the conveying surface is convex upward.

[0050] Taking the lower conveyor device 51 as an example, the lower conveyor device 51 is composed of motor-integrated rollers 57 and a plurality of conveying rollers 1 that are arranged in parallel on frames 55 and 56 arranged in parallel. The frames 55 and 56 are curved in a downward convex shape as shown in FIG. 7(b). And a motor-integrated roller 57 is attached to one end of the frames 55 and 56. Also, in other regions, a plurality of conveying rollers 1 are arranged in parallel. Specifically, a plurality of conveying rollers 1 are attached in parallel.

[0051] Here, in the present embodiment, the positions of the large-diameter portions 30 and the small-diameter portions 31 of the adjacent conveying rollers 1 are in a staggered relationship. That is, when focusing on a specific conveying roller 1, the position of the small-diameter portion 31 of the adjacent conveying roller 1 corresponds to the position of the large-diameter portion 30 of the specific conveying roller 1, and the position of the large-diameter portion 30 of the adjacent conveying roller 1 corresponds to the position of the small-diameter portion 31 of the specific conveying roller 1.

[0052] Also, the axial distance W between the adjacent conveying rollers 1 is shorter than the diameter of the large-diameter portion 30. Therefore, the large-diameter portions 30 and the small-diameter portions 31 of the adjacent conveying rollers 1 are in an interlocked state. That is, when focusing on a specific conveying roller 1, between the large-diameter portions 30 of the specific conveying roller 1, the large-diameter portion 30 of the adjacent conveying roller 1 enters, and the outer contour of the large-diameter portion 30 of the adjacent conveying roller 1 approaches the vicinity of the core member 20 of the specific conveying roller 1. Therefore, as shown in Fig. 7(a), the blade-like pieces 11 of the lower conveyor device 51 are densely arranged, and the entire surface of the lower conveyor device 51 functions as a conveying surface. In other words, in the lower conveyor device 51, the entire surface is an energizing region.

[0053] In the present embodiment, each conveying roller 1 is driven using the roller 57 with a built-in motor as a power source. That is, a driving pulley 35 is provided on the roller 57 with a built-in motor, and a belt 36 is suspended between the driving pulley 35 and one pulley 2 of the adjacent first conveying roller 1. Also, 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 belts 36 are sequentially suspended between the adjacent conveying rollers 1, and by rotating the roller 57 with a built-in motor, all the conveying rollers 1 rotate. In this embodiment, the conveying roller 1 rotates in a direction where the proximal end side of the blade-shaped piece 11 is in the front and the free end side is in the rear. The direction (winding direction) of the blade-shaped piece 11 and the rotation direction of the conveying roller 1 are not limited and may be reversed. Also, blade-shaped pieces 11 with different winding directions may be mixed.

[0054] Assuming that the conveyed object is to be lowered from the upper floor to the lower floor, in the inclined conveyor device 40, the conveying surface of the upper conveyor device 50 is curved convex upward, and the conveying surface of the connecting portion to the inclined region 61 presents a gentle curved surface. Therefore, the conveyed object smoothly transitions to the inclined region 61. Also, in the inclined conveyor device 40 employed in this embodiment, the conveying surface of the lower conveyor device 51 is curved convex downward, and the conveying surface of the connecting portion from the inclined region 61 presents a gentle curved surface. Therefore, the conveyed object smoothly transitions from the inclined region 61 to the lower conveyor device 51.

[0055] Also, in the lower conveyor device 51, as shown in Fig. 7(a), the blade-shaped pieces 11 are densely arranged, and the entire surface of the lower conveyor device 51 functions as a conveying surface. Therefore, the contact opportunity between the conveyed object and the conveying roller 1 is large, and when the conveyed object is transferred from the inclined region 61 to the lower end region 62, the conveyed object is less likely to rattle. In particular, in this embodiment, the conveying roller 1 has a plurality of large-diameter portions (biasing regions) 30, and among them, those with the positions of the blade-shaped pieces 11 shifted are mixed. Therefore, when the conveyed object reaches the lower conveyor device 51 and comes into contact with any of the conveying rollers 1, the conveyed object is supported by any of the blade-shaped pieces 11. Therefore, when the conveyed object is transferred from the inclined region 61 to the lower end region 62, the conveyed object is less likely to rattle.

[0056] Furthermore, when the corner of the conveyed object collides with the lower conveyor device 51 when the conveyed object is transferred from the inclined region 61 to the lower end region 62, the blade-shaped piece 11 of the conveying roller 1 deforms and absorbs the impact. That is, since the blade-like pieces 11 are curved and surround the core member without any gaps, the corners of the conveyed object will hit one of the blade-like pieces 11. Since the blade-like pieces 11 are attached in a cantilever manner, they are easily bent and have a high deformability. Therefore, when the corner of the conveyed object collides with the lower conveyor device 51, the blade-like pieces 11 of the conveying roller 1 are deformed to absorb the impact. Therefore, it is difficult to damage the conveyed object. Also, less noise is generated.

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

[0058] In the embodiment described above, pulleys 2 are provided at both ends of the conveying roller 1, and a belt 36 is suspended on the adjacent conveying roller 1 to sequentially transmit power. However, a plurality of pulleys may be provided on one of the conveying rollers 1, and a belt 36 may be suspended on the adjacent conveying roller 1 to sequentially power it. 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, a gear or a chain may be used.

[0059] In the embodiment described above, the rotating core 6 that engages with the through hole 12 is inserted into the through hole 12 of the rotating core component 10 (shaft portion), and the blade-like pieces 11 are rotated by rotating the rotating core 6 with power. However, the rotating core component 10 (shaft portion) may be freely rotatable with respect to the axis, and a rotational force may be transmitted to the core member 20 constituted by the rotating core component 10 (shaft portion).

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

[0061] It is desirable that the number of the roller pieces 5 is 4 or more. That is, in the conveyor devices 50 and 51 of the present embodiment, the adjacent roller pieces 5 have the positions of the blade-like pieces 11 shifted and different phases. On the other hand, the roller pieces 5 at every other position have the positions of the blade-like pieces 11 coinciding and the same phase. Therefore, if the number of the roller pieces 5 is 4 or more, the conveyed object is supported by the blade-like pieces 11 of a plurality of roller pieces 5 at the same time. Therefore, the conveyed object is less likely to rattle. However, the present invention is not limited to this configuration, and the whole may be integrally formed.

[0062] In the above-described conveying roller 1, the regions where the blade-like pieces 11 are provided on the core member 20 and the regions where the blade-like pieces 11 do not exist alternately exist. According to this configuration, when incorporated into the conveyor device, the axial distance between the conveying rollers 1 can be shortened, and the biasing regions contributing to the conveyance of the conveyed object can be provided densely. That is, what actually contacts the conveyed object is the portion located at the top of the biasing region during rotation. Therefore, valleys are formed between adjacent biasing regions. In the conveyor devices 50 and 51 of the present embodiment, the large-diameter portions 30 and the small-diameter portions 31 of the adjacent conveying rollers 1 are in an interlocked state, and the portions actually contributing to the conveyance are arranged in a staggered pattern, so the contact opportunity with the conveyed object is large 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 all regions in the axial direction of the conveying roller 1.

[0063] The conveying rollers 1 employed in the conveyor devices 50 and 51 described above are all formed by connecting roller pieces 5 having the same shape, but conveying rollers using roller pieces 5 having different shapes may be mixed. For example, in the conveyor device 80 shown in FIG. 9, the conveying rollers 81 having a large ratio of the large-diameter portion (biasing region) 30 and the conveying rollers 82 having a small ratio of the large-diameter portion (biasing region) 30 are arranged alternately. Regarding the conveyor device 80 as well, the axial distance W between the adjacent conveying rollers 81 and 82 is shorter than the diameter of the large-diameter portion 30.

[0064] In the embodiment described above, as an example of the deformed portion, the blade-shaped piece 11 was shown, but the shape of the deformed portion is not limited to the blade-shaped one. FIG. 10 shows a modification example of the deformed portion. The deformed portion 43 adopted by the roller piece 42 shown in FIG. 10(a) is constituted by a linear blade-shaped piece 45. The blade-shaped piece 45 of the roller piece 42 is provided in the normal direction with respect to the rotation core constituent portion (shaft portion) 10. The deformed portion 66 adopted by the roller piece 65 shown in FIG. 10(b) is constituted by a linear blade-shaped piece 67. The blade-shaped piece 67 of the roller piece 65 is provided with a component in the tangential direction with respect to the rotation core constituent portion (shaft portion) 10. The deformed portion 71 adopted by the roller piece 70 shown in FIG. 10(c) has a structure in which the free end sides of all the blade-shaped pieces 72 are annularly connected.
