Embodiments for Carrying Out the Invention

[0024] Next, an embodiment of the present disclosure will be described in detail with reference to the drawings. The diagrams used in the following explanation are all schematic, and the dimensional relationships and ratios of each element shown in the diagrams do not necessarily correspond to reality. Furthermore, the dimensional relationships and ratios of each element do not necessarily correspond between multiple diagrams.

Also, the arrow X in the diagrams indicates the X-axis direction (horizontal), the arrow Y indicates the Y-axis direction (horizontal), and the arrow Z indicates the Z-axis direction (up and down, vertical). The X-axis, Y-axis, and Z-axis directions are mutually orthogonal.

[0025] [Conveying device 10] Figure 1 is a top view of a conveying device 10 according to one embodiment of the present disclosure. Figure 2 is a view of the conveying device 10 from the Y-axis direction in Figure 1. Figures 3(A) and 3(B) are views of the conveying device 10 from the X-axis direction in Figure 1. Note that in Figure 2, the configuration of the downstream conveying section 16 is omitted in order to make the structure of the conveying device 10 easier to understand. Similarly, in Figures 3(A) and 3(B), the configuration of the upstream conveying section 12 is omitted in order to make the structure of the conveying device 10 easier to understand.

[0026] The conveying device 10 is for conveying objects (for example, products M on pallet 1). The conveying device 10 comprises an upstream conveying section 12, a direction changing device 14 for unloading objects brought in from the upstream conveying section 12 in an unloading direction (also called the Y-axis direction) that is approximately perpendicular to the loading direction (also called the X-axis direction) without changing the orientation of the objects, and a downstream conveying section 16 for conveying objects unloaded from the direction changing device 14 to the downstream side. Here, "approximately perpendicular" means within the range of 85 to 95 degrees, and is not limited to 90 degrees. The same applies hereafter.

[0027] (Upstream transport section 12) The upstream transport unit 12 transports the transported material toward the direction changing device 14, which will be described in detail later, without using a drive source, and is located upstream of the direction changing device 14 in the loading direction.

[0028] The upstream transport section 12 includes a pair of roller rows 18a and 18b that extend in the X-axis direction and are rotatable to transport objects in the X-axis direction, and a plurality of legs 20a to 20d that support the roller rows 18a and 18b from below and extend vertically (also called the Z-axis direction). The roller rows 18a and 18b are arranged in parallel on the upper surfaces of the legs 20a to 20d such that their spacing (width) in the Y-axis direction is similar, equal, or identical. The spacing between roller rows 18a and 18b in the Y-axis direction is narrower than the Y-axis width of the pallet 1, and the pallet 1 is configured to be transportable on the roller rows 18a and 18b.

[0029] Each of the roller rows 18a and 18b has a plurality of rollers 22 and a guide member 24 that rotatably supports the upper ends of the plurality of rollers 22 with their upper ends exposed. Each of the plurality of rollers 22 has a cylindrical portion and a rotation axis 26 extending in the Y-axis direction from approximately the center of the cylindrical portion. Each rotation axis 26 is supported by the guide member 24, and the plurality of rollers 22 are configured to rotate around the rotation axis 26 extending in the Y-axis direction.

[0030] The upstream ends of roller rows 18a and 18b in the transport direction (X-axis direction) are supported from below by legs 20a and 20b, respectively. The downstream ends of roller rows 18a and 18b in the transport direction (hereinafter referred to as "transport direction X") are supported from below by legs 20c and 20d, respectively. The upper surfaces of the legs 20a and 20b on the upstream side in transport direction X are positioned higher vertically than the upper surfaces of the legs 20c and 20d on the downstream side in transport direction X. In other words, roller rows 18a and 18b are supported in an inclined state such that the downstream roller rows 18a and 18b in transport direction X are lower than the upstream roller rows 18a and 18b in transport direction X.

[0031] In other words, the upstream conveying section 12 is inclined such that the downstream end of the direction of direction change device 14 in the direction of input (X-axis direction) is lower than the upstream end. To put it another way, the upstream conveying section 12 is inclined such that the downstream end of the conveying section 12 in the conveying direction X is lower than the upstream end of the conveying direction X. Furthermore, the vertical height of the downstream end of the conveying section 12 in the conveying direction X is set to be higher than the direction change device 14 in a horizontal state. As a result, the upstream conveying section 12 can convey objects toward the direction change device 14 without using a drive source.

[0032] Therefore, a drive source is not required to rotate each roller 22 in the upstream conveying section 12. As a result, the conveyed object is transported by its own weight (gravity) from the upstream side to the downstream side on the upstream conveying section 12, and then transported to the direction changing device 14 located downstream of the upstream conveying section 12.

[0033] (Downstream transport section 16) The downstream transport section 16 transports the transported material discharged from the direction changing device 14 without using a drive source, and is located downstream of the direction changing device 14 in the discharge direction.

[0034] The downstream transport section 16 includes a pair of roller rows 28a and 28b extending in the Y-axis direction and rotatable to transport objects in the Y-axis direction, and a plurality of legs 30a to 30d supporting the roller rows 28a and 28b from below and extending in the Z-axis direction. The roller rows 28a and 28b are arranged in parallel on the upper surfaces of the legs 30a to 30d such that their spacing (width) in the X-axis direction is similar, equal, or identical. The spacing between roller rows 28a and 28b in the X-axis direction is narrower than the width of the pallet 1 in the X-axis direction, and the pallet 1 is configured to be transportable on the roller rows 28a and 28b.

[0035] Each of the roller rows 28a and 28b has a plurality of rollers 23 and a guide member 25 that rotatably supports the upper ends of the plurality of rollers 23 with the ends exposed. Each of the plurality of rollers 23 has a cylindrical portion and a rotation axis 27 extending in the X-axis direction from approximately the center of the cylindrical portion. Each rotation axis 27 is supported by the guide member 25, and the plurality of rollers 23 are configured to rotate around the rotation axis 27 extending in the X-axis direction.

[0036] The upstream ends of roller rows 28a and 28b in the transport direction (Y-axis direction) are supported from below by legs 30a and 30b, respectively. The downstream ends of roller rows 28a and 28b in the transport direction (hereinafter referred to as "transport direction Y") are supported from below by legs 30c and 30d, respectively. The upper surfaces of the legs 30a and 30b on the upstream side in the transport direction Y are positioned higher vertically than the upper surfaces of the legs 30c and 30d on the downstream side in the transport direction Y. In other words, roller rows 28a and 28b are supported in an inclined state such that the downstream roller rows 28a and 28b in the transport direction Y are lower than the upstream roller rows 28a and 28b in the transport direction Y.

[0037] In other words, the downstream conveying section 16 is inclined such that the downstream end of the direction-changing device 14 in the discharge direction (Y-axis direction) is lower than the upstream end. To put it another way, the downstream conveying section 16 is inclined such that the downstream end of the conveying direction Y is lower than the upstream end of the conveying direction Y. Furthermore, the vertical height of the upstream end of the downstream conveying section 16 in the conveying direction Y is set to be lower than the downstream end of the direction-changing device 14 in the discharge direction when it is inclined. As a result, the downstream conveying section 16 can convey the transported material discharged from the direction-changing device 14 to the downstream side without using a drive source.

[0038] Therefore, a drive source is not required to rotate each roller 23 in the downstream conveying section 16. As a result, the conveyed object is transported from the upstream side to the downstream side on the downstream conveying section 16 by its own weight (gravity).

[0039] (Direction change device 14) Next, the details of the direction changing device 14 will be explained using Figures 1, 3(A), and 3(B). Figure 3(A) shows the state in which no conveyed goods have been loaded into the direction changing device 14, and Figure 3(B) shows the state in which conveyed goods have been loaded into the direction changing device 14.

[0040] Here, "the state in which no goods are loaded into the direction-changing device 14" includes not only the state in which the pallet 1 with the product M is not loaded onto the base 50 that constitutes the direction-changing device 14, but also the state in which part of the pallet 1 is loaded onto the base 50. Furthermore, "the state in which goods are loaded into the direction-changing device 14" refers to the state in which the entire pallet 1 with the product M is loaded onto the base 50 that constitutes the direction-changing device 14, and does not include the state in which only part of the pallet 1 with the product M is loaded. Note that the pallet 1 with the product M is loaded into the direction-changing device 14 in the state shown in Figure 3(A) (the pallet 1 with the product M is placed on the base 50 when the base 50 is in a horizontal state, as described later), so Figure 3(B) can be said to be a diagram showing the state in which the pallet 1 with the product M that has been loaded into the direction-changing device 14 is unloaded.

[0041] The direction changing device 14 comprises a base 50, legs 52a and 52b as first support parts positioned below the upstream end of the base 50 in the discharge direction (also called the Y-axis direction) and supporting the base 50 in a horizontal state, legs 52c and 52d as second support parts positioned below the downstream end of the base 50 in the discharge direction and supporting the base 50 in an inclined state, and a shaft 54 ​​that supports the base 50 from below and extends in the X-axis direction relative to the base 50. The legs 52a to 52d each extend in the vertical direction (also called the Z-axis direction). The upper surfaces of the legs 52c and 52d are lower in the vertical direction than the upper surfaces of the legs 52a and 52b.

[0042] The platform 50 is composed of a pair of roller rows 38a and 38b that extend in the X-axis direction and are rotatable to load objects in the X-axis direction, and a pair of roller rows 48a and 48b that extend in the Y-axis direction and are rotatable to unload objects in the Y-axis direction. The roller rows 38a and 38b and the roller rows 48a and 48b are integrally constructed using fasteners such as screws so that their upper ends are at the same, equivalent, or identical height, form the same, equivalent, or identical surface, and their relative positions to each other remain constant.

[0043] The roller rows 38a and 38b are arranged in parallel and continuous along the X-axis direction, with the exception of a portion (roller row 28a) of each roller row 18a and 18b. The distance (width) between roller row 38a and roller row 38b in the Y-axis direction is equal to or the same as the distance between roller row 18a and roller row 18b in the Y-axis direction. Furthermore, the distance between roller row 38a and roller row 38b in the Y-axis direction is narrower than the width of pallet 1 in the Y-axis direction, so that pallet 1 can be transported on roller rows 38a and 38b. Roller row 38a constitutes the downstream end in the unloading direction on the platform 50. Roller row 38b constitutes the upstream end in the unloading direction on the platform 50.

[0044] Furthermore, roller rows 48a and 48b are arranged in parallel and continuous along the Y-axis direction on roller rows 28a and 28b, respectively. The distance (width) between roller row 48a and roller row 48b in the X-axis direction is the same as or identical to the distance between roller row 28a and roller row 28b in the X-axis direction. In addition, the distance between roller row 28a and roller row 28b in the X-axis direction is narrower than the width of pallet 1 in the X-axis direction, so that pallet 1 can be transported on roller rows 48a and 48b. Roller row 48a constitutes the upstream end in the loading direction on the platform 50. Roller row 48b constitutes the downstream end in the loading direction on the platform 50.

[0045] Each of the roller rows 38a and 38b has a plurality of first rollers 56 and a guide member 58 that exposes the upper ends of the plurality of rollers 56 and supports them so that they can rotate. Each of the plurality of rollers 56 has a cylindrical portion and a rotation axis 60 extending in the Y-axis direction from approximately the center of the cylindrical portion. Each rotation axis 60 is supported by the guide member 58 and configured so that the plurality of rollers 56 can rotate around the rotation axis 60 extending in the Y-axis direction.

[0046] Each of the roller rows 48a and 48b has a plurality of second rollers 57 and a guide member 59 that exposes the upper ends of the plurality of rollers 57 and supports them so that they can rotate. Each of the plurality of rollers 57 has a cylindrical portion and a rotation axis 61 extending in the X-axis direction from approximately the center of the cylindrical portion. Each rotation axis 61 is supported by the guide member 59 and configured so that the plurality of rollers 57 can rotate around the rotation axis 61 extending in the X-axis direction.

[0047] Rollers 56 and 57 are each chamfered. The chamfering is formed over the entire circumference of both ends of the cylindrical portion of rollers 56 and 57 in the width direction (also called the rotation axis direction). In this way, friction between the pallet 1 and rollers 57 when loading into the direction changing device 14 and friction between the pallet 1 and rollers 56 when unloading from the direction changing device 14 can be reduced.

[0048] The platform 50 is equipped with weights 62 for adjusting the center of gravity of the platform 50. The weights 62 are detachably attached to the underside of the platform 50. The platform 50 is also configured to allow adjustment of the weight of the weights 62 (also known as the number of weights 62) and the installation position of the weights 62. In this way, by adjusting at least one of the weight of the weights 62 and the installation position of the weights 62, the center of gravity of the platform 50 and the transported object can be adjusted according to the weight of the transported object, and the timing of the platform 50's tilt can be adjusted (optimized, etc.).

[0049] In other words, when no goods are loaded onto the platform 50, the weight 62 positions the center of gravity of the platform 50 upstream of the axis 54 in the unloading direction (also called the Y-axis direction) (see Figure 3(A)). When goods are loaded onto the platform 50, the weight 62 shifts the center of gravity of the platform 50, pallet 1, and product M downstream of the axis 54 in the unloading direction (also called the Y-axis direction) (see Figure 3(B)). To enable the platform 50 to perform these actions, the direction changing device 14 adjusts at least one of the weight of the weight 62 and the installation position of the weight 62.

[0050] Specifically, when the leading edge of the pallet 1 carrying product M is moved onto the roller row 48b at the downstream end in the loading direction, and the rear end of the pallet 1 is moved onto the roller row 48a at the upstream end in the loading direction, the base 50, which is supported by legs 52a and 52b and is in a horizontal position, begins to tilt with the shaft 54 ​​as the pivot point, with the downstream end in the loading direction moving downward and the upstream end in the loading direction moving upward. Then, the base 50 maintains its tilted state with the downstream end in the loading direction supported by legs 52c and 52d (see Figure 3(B)). The pallet 1 carrying product M is loaded in the loading direction while the base 50 is maintaining its tilted state. Then, when the rear end of the pallet 1 carrying product M passes over the roller row 38a at the downstream end in the unloading direction, the platform 50, which is tilted and supported by the legs 52c and 52d, returns to a horizontal position with the shaft 54 ​​as the pivot point, and the downstream end of the platform 50 in the unloading direction is supported by the legs 52a and 52b (see Figure 3(A)).

[0051] In this way, the direction changing device 14 maintains the platform 50 in a horizontal position when no object is loaded onto the platform 50. When an object is loaded onto the platform 50, the direction changing device 14 tilts the platform 50 from its horizontal position using the axis 54 as a pivot point, so that the downstream end of the platform 50 in the unloading direction, which is approximately perpendicular to the loading direction, becomes lower, and unloads the object from the X-axis direction to the Y-axis direction.

[0052] [Differentiation] In the above embodiment, the case in which the conveyed material is conveyed by the upstream conveying unit 12 and the downstream conveying unit 16 without using a drive source was described. This disclosure is not limited to the above embodiment, and drive sources may be provided in the upstream conveying unit 12 and the downstream conveying unit 16. Specifically, the power of a drive source such as a motor may be transmitted via multiple gears to the rotation shafts 26 of all the rollers 22 of the upstream conveying unit 12, and to the rotation shafts 27 of all the rollers 23 of the downstream conveying unit 16. In this case, the conveyed material can be loaded into the direction changing device 14 by the horizontally positioned upstream conveying unit 12, and the conveyed material discharged from the direction changing device 14 can be conveyed downstream by the horizontally positioned downstream conveying unit 16.

[0053] Furthermore, in the above embodiment, the description was based on the case where rollers 56 and 57 that can rotate in two directions, the X-axis direction and the Y-axis direction, are used as the base 50 of the direction changing device 14. This disclosure is not limited to the above embodiment, and the direction changing device 14 may also use a base 50 that supports the upper ends of a plurality of rotatable spherical balls with the upper ends exposed. In this case, limiting plates are provided at the downstream end in the loading direction and the upstream end in the unloading direction to restrict the movement of the conveyed object. With this configuration as well, the direction changing device 14 maintains the base 50 in a horizontal state when no conveyed object is loaded onto the base 50, and when conveyed object is loaded onto the base 50, it tilts the base 50 from a horizontal state with the axis 54 as a fulcrum so that the downstream end in the unloading direction, which is approximately perpendicular to the loading direction of the base 50, becomes lower, and unloads the conveyed object from the X-axis direction to the Y-axis direction.

[0054] The embodiments of this disclosure have been described in detail above. However, this disclosure is not limited to the embodiments described above, and can be modified in various ways without departing from its essence.

[0055] For example, in the embodiment described above, the transported item was exemplified as a product M placed on a pallet 1. However, the transported item may consist only of the product without a pallet, or it may be a packaging box (e.g., a cardboard box) in which the product is packed. In other words, the pallet is not an essential component for this disclosure.
