Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, when actually operating a conveyor device such as a roller conveyor in a warehouse or the like, a plurality of conveyor devices may be arranged side by side to construct a large-scale conveyor device. Here, the inventor of the present application considered that in such a conveyor device, a roller member is arranged at a portion that forms a boundary between one adjacent conveyor device and another conveyor device, so as to smooth the movement of the conveyed object from one conveyor device to another conveyor device.

[0006] However, in such a large-scale conveyor device, there may be a case where the height of the conveying surface is different between one conveyor device and another conveyor device. That is, a deviation occurs in the conveying surface of adjacent conveyor devices. In such a case, it is preferable to adjust the installation height of the roller member located at the boundary, but it is necessary to disassemble the conveyor device and move each part, and the adjustment work is complicated.

[0007] An object of the present invention is to provide a conveyor device that can be manufactured at low cost with a simple structure and can facilitate the adjustment work of the installation position of the roller, and a roller mounting member.

Means for Solving the Problems

[0008] One aspect of the present invention for solving the above problems is a conveyor device in which a roller member is attached to a frame member, wherein the frame member is provided with a roller mounting hole which is an elongated hole into which a shaft portion of the roller member can be inserted, the roller mounting hole has a contact portion at one end in the longitudinal direction, and further has a roller mounting member, the roller mounting member has a first piece portion in which a first roller mounting hole is formed, and can be fixed to the frame member in a first posture in which the first roller mounting hole and a part of the roller mounting hole communicate with each other, and by fixing the roller mounting member to the frame member in the first posture and supporting the shaft portion in a state where the roller mounting member contacts the shaft portion inside the first roller mounting hole, the shaft portion is supported at a position different from a state where the shaft portion contacts the contact portion and the roller mounting member further has a second piece portion in which a second roller mounting hole is formed, and the roller mounting member can be fixed to the frame member in one posture selected from the first posture and a second posture in which the second roller mounting hole and a part of the roller mounting hole communicate with each other. The roller mounting member is fixed to the frame member in either the first posture or the second posture, and supports the shaft portion in a state where the shaft portion is in contact with the inside of the first roller mounting hole or the second roller mounting hole. In a state where the roller mounting member is fixed in the first posture and a state where the roller mounting member is fixed in the second posture, the positions where the shaft portion is supported are different, and the first piece portion and the second piece portion are continuous via a boundary portion that is a bent or curved portion A conveyor device characterized by the above.

[0009] In this aspect, by simply removing the roller member from the frame member, fixing the roller mounting member to the frame member, and then attaching the roller member as it is, the roller member can be supported at different positions. From this, the adjustment work for the installation position of the roller can be facilitated. Further, the roller mounting member can have a simple structure in which only a first roller mounting hole is formed in the first piece portion.

[0010] In the above aspect, the roller mounting member further has a second piece portion in which a second roller mounting hole is formed. The roller mounting member can be fixed to the frame member in one posture selected from the first posture and a second posture in which the second roller mounting hole and a part of the roller mounting hole communicate with each other. The roller mounting member is fixed to the frame member in either the first posture or the second posture, and supports the shaft portion in a state where the shaft portion is in contact with the inside of the first roller mounting hole or the second roller mounting hole. In the state where the roller mounting member is fixed in the first posture and the state where it is fixed in the second posture, the positions where the shaft portion is supported are different. Yes.

[0011] According to such an aspect, when fixing the roller mounting member to the frame member, by changing the posture of the roller mounting member and then fixing it, the position where the roller member is supported can be made different positions. That is, it becomes possible to easily support the roller member at various positions, and diversification of the positions where the roller member is supported can be achieved.

[0012] The above-mentioned Aspect is that the first piece portion and the second piece portion are continuous via a boundary portion that is a bent or curved portion. Yes.

[0013] According to such an aspect, alignment during attachment of the roller mounting member can be facilitated.

[0014] In the more preferable aspect described above, it is further preferable that the first roller mounting hole and the second roller mounting hole are each an elongated hole having a different length and are continuous at the boundary portion.

[0015] According to such an aspect, in either the case of inserting the shaft portion inside the first roller mounting hole or the case of inserting the shaft portion inside the second roller mounting hole, the operation of inserting the shaft portion becomes easy.

[0016] In the above-described preferable aspect, an identification portion is provided on at least one of the first piece portion and the second piece portion, and the identification portion indicates the difference in the position where the shaft portion is supported in a state where the roller mounting member taking the first posture supports the shaft portion and in a state where the roller mounting member taking the second posture supports the shaft portion. It is more preferable.

[0017] According to such an aspect, it is possible to suppress the occurrence of problems such as the operator making a mistake in the posture of the roller mounting member when fixing the roller mounting member to the frame member.

[0018] Another aspect of the present invention is a roller mounting member for mounting a roller member to a frame member in a conveyor device, wherein the frame member is provided with a roller mounting hole which is an elongated hole into which the shaft portion of the roller member can be inserted, and the roller mounting hole has a contact portion at one end in the longitudinal direction and has a first piece portion in which a first roller mounting hole is formed, and can be fixed to the frame member in a first posture in which the first roller mounting hole and a part of the roller mounting hole communicate with each other, and is fixed to the frame member in the first posture, and the shaft portion is supported in a state of being in contact with the inside of the first roller mounting hole, whereby the shaft portion is supported at a position different from the state of being in contact with the contact portion. and further has a second piece portion in which a second roller mounting hole is formed, and can be fixed to the frame member in one posture selected from the first posture and a second posture in which the second roller mounting hole and a part of the roller mounting hole communicate with each other. The roller mounting member is fixed to the frame member in either the first posture or the second posture, and supports the shaft portion in a state where the shaft portion is in contact with the inside of the first roller mounting hole or the second roller mounting hole. In a state where the roller mounting member is fixed in the first posture and a state where the roller mounting member is fixed in the second posture, the positions where the shaft portion is supported are different, and the first piece portion and the second piece portion are continuous via a boundary portion that is a bent or curved portion A roller mounting member characterized by the above.

[0019] Also in such an aspect, it is possible to facilitate the adjustment work of the installation position of the roller. Further, the roller mounting member can have a simple structure.

Modes for Carrying Out the Invention

[0022] Hereinafter, the conveyor device 1 according to the embodiment of the present invention will be described in detail with reference to the drawings, but the present invention is not limited to these examples.

[0023] As shown in Fig. 1, the conveyor device 1 of the present embodiment is formed by arranging and connecting two conveyor devices, namely a first conveyor device 2 and a second conveyor device 3. The first conveyor device 2 and the second conveyor device 3 are similar devices. The first conveyor device 2 will be described in detail, and duplicate detailed descriptions of the second conveyor device 3 will be omitted.

[0024] The first conveyor device 2 has a conveyor device main body 10 and an outer frame member 11 (frame member). The conveyor device main body 10 is a so-called transfer device, which is a device capable of conveying a conveyed object in any one of a plurality of directions (one direction selected from a plurality of directions). The conveyor device main body 10 of the present embodiment has a main conveyor section 20, a sub-conveyor section 21, and a lifting mechanism (not shown). The lifting mechanism is a mechanism for lifting at least one of the main conveyor section 20 and the sub-conveyor section 21, and is not particularly limited. However, in the present embodiment, it is a mechanism for lifting both the main conveyor section 20 and the sub-conveyor section 21. That is, the lifting mechanism is a mechanism for lifting one of the main conveyor section 20 and the sub-conveyor section 21 while lowering the other, and lowering one while raising the other.

[0025] The main conveyor section 20 has a plurality of unit bodies 20a. Each unit body 20a is provided with a plurality of roller members, and these roller members are arranged at a predetermined interval in the conveying direction (main conveying direction) of the conveyed object. In this main conveyor section 20, a conveying surface is formed by the upper parts of the plurality of roller members. The "conveying surface" is the part on which the conveyed object is placed when the conveyed object is conveyed by the main conveyor section 20.

[0026] The sub-conveyor section 21 is a roller conveyor and includes two conveyor frames 21a (frame members) extending parallel to each other and a plurality of conveyor rollers 21b (driving bodies). For ease of drawing, only a part of the conveyor rollers 21b are labeled, and labels for the others are omitted. Similarly, for other members, labels are attached only to a part as necessary, and labels for the others are omitted.

[0027] The plurality of conveyor rollers 21b are each rotatably supported by the two conveyor frames 21a and are arranged at predetermined intervals in the conveyance direction (sub-conveyance direction) of the conveyed object. In this sub-conveyor section 21, a conveyance surface is formed by the upper portions of the plurality of conveyor rollers 21b. The "conveyance surface" is the portion on which the conveyed object is placed when the sub-conveyor section 21 conveys the conveyed object. Also, the unit body 20a of the main conveyor section 20 described above is arranged at a position between two adjacent conveyor rollers 21b in plan view.

[0028] In the first conveying device 2, as described above, the main conveyor section 20 and the sub-conveyor section 21 are moved up and down by the elevating mechanism. As a result, the state where the conveyance surface of the main conveyor section 20 is at a higher position than the conveyance surface of the sub-conveyor section 21 and the state where the conveyance surface of the main conveyor section 20 is at a lower position than the conveyance surface of the sub-conveyor section 21 are switched. When the conveyance surface of the main conveyor section 20 is at a high position, the introduced conveyed object is conveyed in the main conveyance direction. On the other hand, when the conveyance surface of the main conveyor section 20 is at a low position, the introduced conveyed object is conveyed in the sub-conveyance direction. In this embodiment, the main conveyance direction and the sub-conveyance direction are orthogonal to each other in plan view, and the main conveyance direction is orthogonal to the longitudinal direction of the conveyor frame 21a in plan view.

[0029] In the first transfer device 2 of the present embodiment, two outer frame members 11 are arranged at positions separated in a predetermined direction and extend parallel to each other. And a transfer device main body 10 is arranged between the two outer frame members 11. Specifically, the two outer frame members 11 are arranged at positions separated in one direction of the horizontal direction and in the transfer direction (main transfer direction) of the transfer device main body 10 located therebetween.

[0030] That is, one outer frame member 11 is arranged at a position adjacent to the outside of one conveyor frame 21a. Similarly, the other outer frame member 11 is arranged at a position adjacent to the outside of the other conveyor frame 21a. And each outer frame member 11 extends in the same direction as the conveyor frame 21a.

[0031] As shown in FIG. 2, the outer frame member 11 has a top plate portion 25, a bottom plate portion 26, and a side wall portion 27, and these are continuously formed in a substantially U shape. Both the top plate portion 25 and the bottom plate portion 26 are flat plate-like portions and are arranged to face each other with a space therebetween in the vertical direction. The side wall portion 27 is a vertical plate-like portion, the upper end side portion is continuous with the top plate portion 25, and the lower end side portion is continuous with the bottom plate portion 26. Here, the outer frame member 11 of the present embodiment is arranged in a state where the side wall portion 27 is located on the side of the conveyor frame 21a close to the inside. That is, the side wall portion 27 is arranged between the ends on the conveyor frame 21a side of the top plate portion 25 and the bottom plate portion 26, and the space between the top plate portion 25 and the bottom plate portion 26 is an open space on the outside (opposite to the transfer device main body 10 side).

[0032] As shown in FIG. 1, a plurality of roller attachment portions 30 are provided at positions separated in the longitudinal direction on the outer frame member 11 of the present embodiment. This roller attachment portion 30 is a portion where an inter-device roller 31 (roller member) can be attached. Note that, as shown in FIG. 1 and the like, the outer frame member 11 is located between two conveying devices (conveying device main body 10) in a plan view. In other words, it is located between the conveying surfaces of one conveying device and the conveying surface of the other conveying device among the two conveying devices. Therefore, the outer frame member 11 is a frame member arranged between two conveying devices (at the boundary position), and the inter-device roller 31 attached to this outer frame member 11 is a roller attached between two conveying devices.

[0033] As shown in FIG. 2, the inter-device roller 31 has a roller body 31a with a substantially cylindrical shape in general outline and a shaft portion 31b. The shaft portion 31b protrudes outward from each of both end portions in the longitudinal direction of the roller body 31a. The shaft portion 31b in the present embodiment is not particularly limited, but is a rod-shaped member having a substantially hexagonal cross-sectional shape and extending.

[0034] In the roller attachment portion 30, a part of the top plate portion 25 and the side wall portion 27 is missing. Further, in the roller attachment portion 30, two attachment plate portions 35 are respectively arranged at positions separated in the longitudinal direction of the outer frame member 11 and are spaced apart and opposed to each other. Although not particularly limited, in the present embodiment, the two attachment plate portions 35 are connected via a vertical plate-shaped connecting plate portion.

[0035] The attachment plate portion 35 is a vertical plate-shaped portion, and the thickness direction thereof is the same as the longitudinal direction of the outer frame member 11. In the present embodiment, the top plate portion 25 and the attachment plate portion 35 are arranged so as to form an L shape (substantially L shape) and are connected (joined) to each other. That is, the attachment plate portion 35 is arranged below the top plate portion 25, and the upper surface of the attachment plate portion 35 is in contact with the lower surface of the top plate portion 25. Further, the top plate portion 25 and the attachment plate portion 35 are arranged such that the end surface facing the missing portion side of the top plate portion 25 and one main surface of the attachment plate portion 35 are located in the same plane (or substantially the same plane). And a corner portion 30a is formed at a portion that is the boundary between the upper surface (top surface) of the top plate portion 25, the end surface of the top plate portion 25, and one main surface of the attachment plate portion 35.

[0036] In this embodiment, a roller mounting hole 38 is formed so as to straddle the mounting plate portion 35 and the top plate portion 25. This roller mounting hole 38 has a vertical hole portion 40 which is a long hole portion (notch portion) extending in the vertical direction (or substantially vertical direction), and a horizontal hole portion 41 which is a long hole portion (notch portion) extending in the horizontal direction (or substantially horizontal direction). That is, the roller mounting hole 38 is formed integrally with a vertical hole portion 40 provided in the mounting plate portion 35 and a horizontal hole portion 41 provided in the top plate portion 25 and extending in the longitudinal direction of the outer frame member 11. And a part of the horizontal hole portion 41 is located above the vertical hole portion 40. Further, the vertical hole portion 40 and the horizontal hole portion 41 penetrate the mounting plate portion 35 and the top plate portion 25 in the thickness direction.

[0037] This vertical hole portion 40 enables the shaft portion 31b of the inter-device roller 31 to be inserted from above or from the side. Here, the length in the width direction of the vertical hole portion 40 is set to a size such that the shaft portion 31b of the inserted inter-device roller 31 fits exactly. That is, the shaft portion 31b of the inter-device roller 31 can slide along the longitudinal direction of the vertical hole portion 40 while being inserted into the vertical hole portion 40.

[0038] The vertical hole portion 40 has a frame-side mounting portion 40a (contact portion, frame-side contact portion) on its lower end side portion on which the shaft portion 31b of the inter-device roller 31 can be placed. The frame-side mounting portion 40a has a shape in which a part of the shaft portion 31b fits exactly, and when the shaft portion 31b is placed, the placed shaft portion 31b does not rotate around the axis. That is, the frame-side mounting portion 40a comes into an engaged state in which it engages with a part of the shaft portion 31b by bringing the shaft portion 31b into contact (placement), and in the engaged state, the shaft portion 31b does not rotate around the axis. Specifically, the frame-side mounting portion 40a of this embodiment has inclined surface portions on one side and the other side in the width direction of the vertical hole portion 40. And both of these two inclined surface portions have a downward gradient as they go toward the center side in the width direction of the vertical hole portion 40.

[0039] In the roller mounting portion 30 of the present embodiment, roller mounting holes 38 are arranged at positions separated in the longitudinal direction of the outer frame member 11. When attaching the inter-device roller 31 to the outer frame member 11, one shaft portion 31b and the other shaft portion 31b of the inter-device roller 31 can be inserted into different roller mounting holes 38 and mounted on different frame-side mounting portions 40a, respectively. In addition, in the conveyor device 1 of the present embodiment, when attaching the inter-device roller 31 to the outer frame member 11, as shown in FIG. 2, it is also possible to attach it via an attachment auxiliary member 45 (roller attachment member).

[0040] That is, when attaching the inter-device roller 31 to the outer frame member 11 which is the object to be fixed, the conveyor device 1 can perform direct attachment without using two attachment auxiliary members 45 and attachment with a member interposed using two attachment auxiliary members 45. In direct attachment, the shaft portion 31b of the inter-device roller 31 is placed (contacted) on the outer frame member 11, and in attachment with a member interposed, the shaft portion 31b of the inter-device roller 31 is placed (contacted) on the attachment auxiliary member 45 (details will be described later).

[0041] The attachment auxiliary member 45 is a characteristic member of the present embodiment and is a height adjustment member for adjusting the installation height of the inter-device roller 31 (shaft portion 31b) (details will be described later). As shown in FIG. 3, this attachment auxiliary member 45 is a metal member having an outer shape that is substantially L-shaped plate-like. That is, each of the attachment auxiliary members 45 has a plate-like first plate portion 50 (first piece portion) and a second plate portion 51 (second piece portion), and the first plate portion 50 and the second plate portion 51 are continuous while being bent or curved at a boundary portion 52.

[0042] The first plate portion 50 has a first roller shaft attachment portion 60 (first roller attachment hole), a first identification portion 61 (identification portion), and a first fixing hole 62.

[0043] The first roller shaft mounting portion 60 is a long hole portion (notch portion) that penetrates the first plate portion 50 in the thickness direction, and one end portion in the longitudinal direction is located at the boundary portion 52. That is, the first roller shaft mounting portion 60 extends in a direction away from the boundary portion 52. That is, the first roller shaft mounting portion 60 extends linearly toward the end portion on the side opposite to the boundary portion 52 side of the first plate portion 50.

[0044] The length in the width direction of the first roller shaft mounting portion 60 is the same as or substantially the same as the length in the width direction of the above-described vertical hole portion 40 (see FIG. 2). That is, it is sized such that the shaft portion 31b of the inter-device roller 31 fits exactly. And this first roller shaft mounting portion 60 is shorter in the longitudinal direction than the above-described vertical hole portion 40.

[0045] Also, a first mounting portion 60a (first mounting member side contact portion) is formed at the other end portion in the longitudinal direction of the first roller shaft mounting portion 60. This first mounting portion 60a has the same shape as the above-described frame side mounting portion 40a (see FIG. 2). That is, when the shaft portion 31b is mounted, it is a shape that engages with a part of the shaft portion 31b, and is a shape in which the shaft portion 31b does not rotate around the axis in the engaged state.

[0046] The first identification portion 61 is an engraved portion engraved to indicate characters or the like, or a raised portion formed to protrude more than the surroundings. In this embodiment, it indicates the character "high". Here, the "characters or the like" means one or a combination of a plurality selected from characters, numbers, symbols, figures, patterns, or other signs, and the same applies hereinafter. That is, the first identification portion 61 is a portion that indicates (identifies) predetermined information to the user. The first identification portion 61 of this embodiment indicates the installation height of the inter-device roller 31 when the mounting auxiliary member 45 is interposed in the first posture (details will be described later).

[0047] The first fixing hole 62 is a through hole that penetrates the first plate portion 50 in the thickness direction, and is a hole through which a temporary fastening element such as a screw can be inserted. Note that the "temporary fastening element" is a type of fastening element that is a superordinate concept such as a screw or a combination of a bolt and a nut, and is a fastening element that can be fastened and released without being destroyed in principle. In the present embodiment, the first fixing hole 62 is formed at a position linearly aligned with at least a part of the first roller shaft mounting portion 60, and at a position farther from the boundary portion 52 than the first mounting portion 60a of the first roller shaft mounting portion 60 (a position close to the end portion on the opposite side of the boundary portion 52).

[0048] The second plate portion 51 has a second roller shaft mounting portion 65 (second roller mounting hole), a second identification portion 66 (identification portion), and a second fixing hole 67.

[0049] The second roller shaft mounting portion 65 is a long hole portion (notch portion) that penetrates the second plate portion 51 in the thickness direction, and one end portion in the longitudinal direction is located at the boundary portion 52. That is, the second roller shaft mounting portion 65 extends in a direction away from the boundary portion 52. That is, the second roller shaft mounting portion 65 extends linearly toward the end portion on the side opposite to the boundary portion 52 side of the second plate portion 51.

[0050] The length in the width direction of the second roller shaft mounting portion 65 is the same as or substantially the same as the length in the width direction of the vertical hole portion 40 (see FIG. 2) and the first roller shaft mounting portion 60 described above. That is, it is a size such that the shaft portion 31b of the inter-device roller 31 fits exactly. And this second roller shaft mounting portion 65 is shorter in the longitudinal direction than the above-described vertical hole portion 40 and longer in the longitudinal direction than the first roller shaft mounting portion 60.

[0051] Also, a second mounting portion 65a (second mounting member side contact portion) is formed at the other end portion in the longitudinal direction of the second roller shaft mounting portion 65. This second mounting portion 65a has the same shape as the above-described frame side mounting portion 40a (see FIG. 2) and the second mounting portion 65a. That is, when the shaft portion 31b is mounted, it is a shape that engages with a part of the shaft portion 31b, and is a shape in which the shaft portion 31b does not rotate around the axis in the engaged state.

[0052] Here, the first roller shaft mounting portion 60 and the second roller shaft mounting portion 65 form a series of holes that are continuous at the boundary portion 52. That is, the first roller shaft mounting portion 60 and the second roller shaft mounting portion 65 are different portions of a single long hole. In addition, the first roller shaft mounting portion 60 and the second roller shaft mounting portion 65 form a series of surfaces on the inner surfaces at one end portion in the width direction of each. In addition, a series of surfaces are also formed on the inner surfaces at the other end portion in the width direction.

[0053] The second identification portion 66 is a printed portion printed to indicate characters or the like, or a raised portion formed to be raised more than the surroundings. In the present embodiment, it indicates the character "middle". This second identification portion 66 is also a portion that indicates (identifies) predetermined information to the user. The second identification portion 66 of the present embodiment indicates the installation height of the inter-device roller 31 when the attachment auxiliary member 45 is interposed in the second posture (details will be described later).

[0054] The second fixing hole 67 is a through hole that penetrates the second plate portion 51 in the thickness direction and is a hole through which a temporary fastening element can be inserted. In the present embodiment, it is a position linearly aligned with at least a part of the second roller shaft mounting portion 65, and the second fixing hole 67 is formed at a position farther from the boundary portion 52 than the second mounting portion 65a of the second roller shaft mounting portion 65 (a position close to the end portion opposite to the boundary portion 52).

[0055] As shown in FIG. 4, the attachment auxiliary member 45 of the present embodiment can be attached around the corner portion 30a where the roller attachment hole 38 is formed among the roller attachment portions 30 of the outer frame member 11. At this time, the attachment auxiliary member 45 can be attached to the outer frame member 11 in different postures. Specifically, it is possible to select and attach either the first posture in which the first plate portion 50 is erected (see FIG. 4(a)) or the second posture in which the second plate portion 51 is erected (see FIG. 4(b)).

[0056] As shown in Fig. 4(a), the first posture is such that the first plate portion 50 is in a vertical plate shape and the second plate portion 51 is in a flat plate shape. When attaching the attachment auxiliary member 45 to the outer frame member 11 in the first posture, the corner portion (boundary portion 52) of the attachment auxiliary member 45 is applied to the corner portion 30a of the outer frame member 11 from the outside. As a result, the first plate portion 50 is in a state of being applied to the attachment plate portion 35, and the second plate portion 51 is in a state of being placed on the top plate portion 25.

[0057] Then, while the corner portion of the attachment auxiliary member 45 is being applied, the attachment auxiliary member 45 is slid as necessary to align the position of the second fixing hole 67 of the attachment auxiliary member 45 with the attachment hole of the outer frame member 11, and a temporary fastening element is inserted therethrough. As a result, the attachment auxiliary member 45 is fixed to the outer frame member 11. In this embodiment, since alignment is possible while sliding in this way, the alignment work is easy.

[0058] In the state where the attachment auxiliary member 45 is attached (fixed) in the first posture, as shown in Fig. 5(a), the thickness directions of the first plate portion 50 and the attachment plate portion 35 are in the same direction (or substantially the same direction). Specifically, in a state where the first plate portion 50 and the attachment plate portion 35 are in surface contact with each other, the first plate portion 50 and the attachment plate portion 35 overlap in the horizontal direction. Also, the thickness directions of the second plate portion 51 and the top plate portion 25 are in the same direction (or substantially the same direction). Specifically, in a state where the lower surface of the second plate portion 51 and the upper surface of the top plate portion 25 are in surface contact with each other, the second plate portion 51 and the top plate portion 25 overlap in the vertical direction. Then, the first roller shaft attachment portion 60 and the vertical hole portion 40 overlap in the horizontal direction to form a communication hole, and the second roller shaft attachment portion 65 and the horizontal hole portion 41 overlap in the vertical direction to form a communication hole.

[0059] In this way, when the second roller shaft mounting portion 65 and the horizontal hole portion 41 overlap, when inserting the shaft portion 31b of the inter-device roller 31 into the first roller shaft mounting portion 60, this portion functions as a space for the shaft portion 31b to pass through, so that the shaft portion 31b can be inserted from above. That is, the operation of inserting the shaft portion 31b into the first roller shaft mounting portion 60 can be facilitated.

[0060] Also, when the mounting auxiliary member 45 is fixed in the first posture, the lower end portion (the first mounting portion 60a) of the first roller shaft mounting portion 60 is at a higher position than the lower end portion (the frame-side mounting portion 40a) of the vertical hole portion 40. Then, as shown in FIG. 5(a), by attaching both of the two mounting auxiliary members 45 to the outer frame member 11 in the first posture, the shaft portions 31b at both ends of the inter-device roller 31 can be placed on different first mounting portions 60a respectively. That is, in this way, the inter-device roller 31 can be attached to the outer frame member 11 in a state where the inter-device roller 31 is supported by the two mounting auxiliary members 45 in the first posture. In the attachment of the inter-device roller 31 with the two mounting auxiliary members 45 in the first posture (hereinafter also referred to as the first attachment), compared with the above-described direct attachment (when each of the shaft portions 31b is placed on the frame-side mounting portion 40a), the inter-device roller 31 can be supported at a higher position.

[0061] The second posture is a posture in which, as shown in FIG. 4(b), the first plate portion 50 is flat and the second plate portion 51 is vertical. Since the details of the procedure for attaching (fixing) the mounting auxiliary member 45 in the second posture are substantially the same as those for attaching (fixing) in the first posture, detailed description is omitted.

[0062] When the attachment auxiliary member 45 is fixed in the second posture, as shown in FIG. 5(b), the thickness directions of the second plate portion 51 and the attachment plate portion 35 become the same direction (or substantially the same direction). Specifically, in a state where the second plate portion 51 and the attachment plate portion 35 are in surface contact, the second plate portion 51 and the attachment plate portion 35 overlap in the horizontal direction. Also, the thickness directions of the first plate portion 50 and the top plate portion 25 become the same direction (or substantially the same direction). Specifically, the lower surface of the first plate portion 50 and the upper surface of the top plate portion 25 are in surface contact, and the first plate portion 50 and the top plate portion 25 overlap in the vertical direction. Then, the second roller shaft attachment portion 65 and the vertical hole portion 40 overlap in the horizontal direction to form a communication hole, and the first roller shaft attachment portion 60 and the horizontal hole portion 41 overlap in the vertical direction to form a communication hole. Even in this second posture, since the first roller shaft attachment portion 60 and the horizontal hole portion 41 overlap, the operation of inserting the shaft portion 31b into the second roller shaft attachment portion 65 can be facilitated.

[0063] Thus, when the attachment auxiliary member 45 is fixed in the second posture, the lower end portion (second placement portion 65a) of the second roller shaft attachment portion 65 becomes higher than the lower end portion (frame-side placement portion 40a) of the vertical hole portion 40. Note that the position of the second placement portion 65a at this time is lower than the position of the first placement portion 60a (see FIG. 5(b)) when the attachment auxiliary member 45 is attached in the first posture. Then, as shown in FIG. 5(b), by attaching both two attachment auxiliary members 45 to the outer frame member 11 in the second posture, the shaft portions 31b at both ends of the inter-device roller 31 can be placed on different second placement portions 65a, respectively. That is, in a state where the inter-device roller 31 is supported by two attachment auxiliary members 45 in the second posture like this, the inter-device roller 31 can be attached to the outer frame member 11. In the attachment of the inter-device roller 31 with these two attachment auxiliary members 45 in the second posture (hereinafter also referred to as the second attachment), the support height (attachment height) of the inter-device roller 31 can be set higher than the above-described direct attachment and lower than the above-described first attachment.

[0064] From the above, in the conveyor device 1 of the present embodiment, when attaching the inter-device roller 31, by directly attaching it or selecting and attaching any one of the first attachment and the second attachment, the inter-device roller 31 can be attached at different heights. That is, in the conveyor device 1 of the present embodiment, the support height (attachment height and installation height) of the inter-device roller 31 can be changed (adjusted).

[0065] Note that the attachment auxiliary member 45 of the present embodiment has the first identification portion 61 and the second identification portion 66 as described above (see FIG. 3). Therefore, when attaching the attachment auxiliary member 45 to the outer frame member 11, by the user visually recognizing the identification portion, it is possible to confirm whether the portion attached to the attachment plate portion 35 is the first plate portion 50 or the second plate portion 51. That is, when attaching the attachment auxiliary member 45, it is possible to prevent the occurrence of problems such as the user attaching the attachment auxiliary member 45 in the wrong posture.

[0066] Incidentally, as described above, the first identification portion 61 indicates the character "high". That is, by attaching the first plate portion 50 to the attachment plate portion 35 (superposing the vertical hole portion 40 and the first roller shaft attachment portion 60 as the first posture), it indicates that the inter-device roller 31 is attached at a high position. Further, as described above, the first identification portion 61 indicates the character "medium". That is, by attaching the second plate portion 51 to the attachment plate portion 35 (superposing the vertical hole portion 40 and the second roller shaft attachment portion 65 as the second posture), it indicates that the inter-device roller 31 is attached at a medium position. Note that the medium position is a position higher than the above-described direct attachment that results in a low position and lower than the above-described first attachment that results in a high position.

[0067] In the above-described embodiment, an example in which the transfer device main bodies 10 of the first transfer device 2 and the second transfer device 3 are used as the transfer device has been described, but the present invention is not limited to this. The transfer device main body may be a transfer device in which the transfer direction is the position direction, such as a normal belt conveyor or a roller conveyor.

[0068] In the above-described embodiment, an example of attaching the inter-device roller 31 by member-interposed attachment with the attachment auxiliary member 45 interposed therebetween has been shown, but the present invention is not limited thereto. For example, in a roller conveyor, when attaching (pivotally supporting) a conveyor roller (roller member) to a conveyor frame (frame member), a structure may be adopted in which the above-described direct attachment and member-interposed attachment can be selected.

[0069] In the above-described embodiment, an example in which identification parts (first identification part 61, second identification part 66) are provided on both the first plate part 50 and the second plate part 51 has been shown, but the present invention is not limited thereto. For example, an identification part may be provided only on one side. For example, an identification part is provided only on the first plate part 50, and a structure is adopted in which the second plate part 51 is not provided with an identification part. In this case, it can be understood that the hole formed in the first plate part 50 having the identification part is a hole for supporting the roller member at a high position, and the hole formed in the second plate part 51 having no identification part is a hole for supporting the roller member at a middle position. At this time, the first identification part 61 may be a symbol such as "〇", for example.

[0070] In the above-described embodiment, an example in which the lengths in the width direction of the first roller shaft attachment part 60 and the second roller shaft attachment part 65 are the same as or substantially the same as the length in the width direction of the vertical hole part 40 has been shown, but the present invention is not limited thereto. The lengths in the width direction of these may be sufficiently longer than the length in the width direction of the vertical hole part 40.

[0071] In the conveyor device 1 of the above-described embodiment, an example in which a plurality (two) of inter-device rollers 31 are attached in a state of being arranged in a row at intervals has been shown, but the present invention is not limited thereto. For example, as shown in FIG. 6, the inter-device rollers 31 may be attached in a matrix. That is, a plurality of (two) rows of inter-device rollers 31 may be provided. Also, the inter-device rollers 31 do not necessarily have to be arranged in a row. For example, they may be attached at two locations separated in a diagonal direction in plan view, that is, at two locations separated in both the parallel direction of the two outer frame portions 111 (X direction in FIG. 6) and the longitudinal direction of the two outer frame portions 111 (Y direction in FIG. 6). The number and position of the inter-device rollers 31 arranged between the two transfer devices (transfer device main body 10) may be changed as appropriate.

[0072] The attachment auxiliary member 45 of the above-described embodiment can also be used when attaching a roller member to a conveyor device 200 having a branch portion as shown in FIG. 7. The conveyor device 200 of the present embodiment includes an upstream conveyor 201, a transfer device 202 capable of switching the transfer direction, a downstream conveyor 203, and a sub-conveyor 204. The upstream conveyor 201, the downstream conveyor 203, and the sub-conveyor 204 are roller conveyors in the present embodiment, and include a pair of conveyor frames extending parallel to each other and a plurality of transfer rollers attached to the conveyor frames.

[0073] This conveyor device 200 can convey the conveyed object in the main conveyance path composed of the upstream conveyor 201, the transfer device 202, and the downstream conveyor 203, and can also convey the conveyed object in the sub-conveyance path composed of the sub-conveyor 204. That is, the transfer device 202 is arranged at the branch portion of the conveyor device 200, and it is possible to convey the conveyed object from the upstream to the downstream conveyor 203 and to the sub-conveyor 204.

[0074] In the conveyor device 200 of the present embodiment, an inter-device frame member 211 is provided between the transfer device 202 and the sub-conveyor 204. The inter-device frame member 211 has the above-described roller mounting portion 30, and the inter-device roller 31 is mounted via the mounting auxiliary member 45. In the inter-device frame member 211 of the present embodiment, two roller mounting portions 30 are provided at positions separated in the longitudinal direction of the inter-device frame member 211 (the conveyance direction of the main conveyance path). And the inter-device roller 31 is mounted via the mounting auxiliary member 45 to each of the two roller mounting portions 30.

[0075] The inter-device frame member 211 may be provided at a position between the upstream conveyor 201 and the transfer device 202 or at a position between the downstream conveyor 203. That is, it may be provided between any two conveyor devices. Further, the inter-device roller 31 may be, for example, attached by extending a pair of conveyor frames belonging to the sub-conveyor 204 and attaching it to this conveyor frame. When two conveyor devices are arranged side by side, the inter-device roller 31 may be attached at a position adjacent to the downstream side of the conveyance surface of the upstream conveyor device (or at a position slightly separated from the downstream side). Similarly, the conveyor frame of the upstream conveyor 201 or the downstream conveyor 203 may be extended, and the inter-device roller 31 may be attached to this conveyor frame. Naturally, the attachment of these inter-device rollers 31 is carried out via the attachment auxiliary member 45 as necessary.
