Modes for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described in detail. For the sake of convenience of explanation, members having the same functions as those shown in each embodiment are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

[0011] [Embodiment 1] An embodiment of the present invention will be described with reference to FIGS. 1 to 3.

[0012] (Overview of the transfer system) FIG. 1 is a perspective view showing an overview of the transfer system 1 according to the present embodiment. FIG. 2 is a plan view showing an overview of the transfer system 1. The transfer system 1 is for transferring articles 2 in a logistics warehouse or the like. As shown in FIGS. 1 and 2, the transfer system 1 of the present embodiment includes a conveyance unit 11, a transfer unit 12, a camera unit 13, a support frame 14, a control unit 15, and a terminal unit 16.

[0013] (Conveyance unit) The conveyance unit 11 conveys the first container 17 and the second container 18 that accommodate the articles 2 in the Y direction (front-rear direction, first direction). Specifically, the conveyance unit 11 includes loading conveyors 11a and 11b provided on the lower side in the Z direction and unloading conveyors 11c and 11d provided on the upper side in the Z direction. The first container 17 and the second container 18 are respectively conveyed to the front side in the Y direction by the loading conveyors 11a and 11b. Also, the first container 17 and the second container 18 are respectively conveyed to the rear side in the Y direction by the unloading conveyors 11c and 11d.

[0014] Furthermore, the conveyance unit 11 includes a moving mechanism 11e and a housing 11f. The moving mechanism 11e sequentially moves the first container 17 from the loading conveyor 11a to the first transfer position P1 and sequentially moves the second container 18 from the loading conveyor 11b to the second transfer position P2. Also, the moving mechanism 11e sequentially moves the first container 17 arranged at the first transfer position P1 to the unloading conveyor 11c and sequentially moves the second container 18 arranged at the second transfer position P2 to the unloading conveyor 11c. The housing 11f houses the moving mechanism 11e.

[0015] (Transfer unit) The transfer unit 12 is installed on the front end side (one end side) in the Y direction of the transport unit 11, holds the article 2 accommodated in the first container 17 arranged at the first transfer position P1, and transfers it to the second container 18 arranged at the second transfer position P2. The transfer unit 12 is installed by a gantry or the like (not shown) above the Z direction of the moving mechanism 11e and the housing 11f of the transport unit 11.

[0016] The transfer unit 12 includes a picking head 12a that holds the article 2, and a drive unit 12b that moves the picking head 12a up and down in the Z direction and moves the picking head 12a in two directions in the X direction and the Y direction in a plan view. The picking head 12a is composed of, for example, one or more suction pads that adsorb the article 2. The picking head 12a adsorbs the article 2 accommodated in the first container 17 from above and holds the article 2 in a suspended state.

[0017] The drive unit 12b includes a fixed rail 12c, a first movable rail 12d, a second movable rail 12e, and a support arm 12f. The fixed rail 12c is installed along the X direction. The first movable rail 12d is installed along the Z direction and reciprocates in the X direction along the fixed rail 12c. The second movable rail 12e is installed along the Y direction and reciprocates in the Z direction along the first movable rail 12d.

[0018] The support arm 12f is installed along the Z direction and reciprocates in the Y direction along the second movable rail 12e. Further, the picking head 12a is attached to the lower side in the Z direction of the support arm 12f. Thereby, the transfer unit 12 can reciprocate the picking head 12a in three directions of XYZ by controlling the operation of the drive unit 12b.

[0019] The transfer unit 12 has a simpler structure than a transfer unit such as a 6-axis robot, for example, and is more adaptable to a multi-row conveyor layout. Therefore, by using the transfer unit 12, the degree of freedom in the layout design of the transfer system 1 is improved.

[0020] (Camera unit) The camera unit 13 is disposed above the transfer unit 12 and is configured to photograph the article 2. The camera unit 13 includes a first camera 13a and a second camera 13b. The first camera 13a photographs one or more articles 2 accommodated in the first container 17 by photographing the first container 17 disposed at the first transfer position P1. The second camera 13b photographs one or more articles 2 accommodated in the second container 18 by photographing the second container 18 disposed at the second transfer position P2. Note that the camera unit 13 may include lights 13c and 13d and a reflector 13e.

[0021] (Support Frame) The support frame 14 is a frame that supports the camera unit 13. The support frame 14 includes support portions 14a and 14a that are respectively installed adjacent to the transfer unit 12 in the X direction (left - right direction, second direction) orthogonal to the Y direction in a plan view, and beam members 14b and 14b that are installed between the support portions 14a and 14a. The first camera 13a and the second camera 13b are installed at appropriate positions on the beam member 14b on the front side in the Y direction. Note that the beam member 14b may be one, or three or more.

[0022] Each of the support portions 14a and 14a includes two column members 14c and 14d, a girder member 14e, and a reinforcing member 14f. The column members 14c and 14d are arranged in the Y direction and are fixed to the installation location of the transfer system 1 by fixing members 14g and 14h. The girder member 14e and the reinforcing member 14f are installed between the column members 14c and 14d.

[0023] Note that the beam members 14b and 14b may be installed on the girder member 14e or on the column members 14c and 14d. Also, the reinforcing member 14f may be two or more, or may be omitted. Further, when each of the support portions 14a and 14a is erected by four or more column members, the beam members 14b and 14b may be omitted. In this case, the first camera 13a and the second camera 13b may be respectively installed at appropriate positions on the support portions 14a and 14a.

[0024] In the examples of FIGS. 1 and 2, on the beam member 14b where the first camera 13a and the second camera 13b are installed, the reflector 13e is installed so as to project outwards on both sides in the Y direction. Also, lights 13c and 13d are respectively installed at appropriate positions of the reinforcing members 14f and 14f in the support portions 14a and 14a. Thereby, the light from the lights 13c and 13d is reflected by the reflector 13e, and the first container 17 and the second container 18 can be illuminated.

[0025] (Control unit) The control unit 15 controls each part in the transfer system 1. The terminal unit 16 is for an operator to perform operations on the transfer system 1.

[0026] In the transfer system 1 having the above configuration, the control unit 15 first instructs the loading conveyors 11a and 11b of the conveying unit 11 to carry in the first container 17 and the second container 18 from the rear in the Y direction to the front end in the Y direction, and continues this. Also, the control unit 15 instructs the unloading conveyors 11c and 11d of the conveying unit 11 to carry out the first container 17 and the second container 18 from the front end in the Y direction to the rear in the Y direction, and continues this.

[0027] Next, the control unit 15 instructs the moving mechanism 11e of the conveying unit 11 to move the loaded first container 17 and second container 18 to the first transfer position P1 and the second transfer position P2 respectively. Next, the control unit 15 instructs the transfer unit 12 based on the captured images of the first container 17 and the second container 18 captured by the camera unit 13, holds the article 2 accommodated in the first container 17 at the first transfer position P1, and transfers it to the second container 18 at the second transfer position.

[0028] Next, the control unit 15 instructs the moving mechanism 11e of the conveying unit 11 to move the first container 17 at the first transfer position P1 to the unloading conveyor 11c, and at the same time, move another loaded first container 17 to the first transfer position P1, instructs the transfer unit 12 to perform the above transfer, and repeats this. The first container 17 moved to the unloading conveyor 11c is carried out to the rear in the Y direction.

[0029] Then, when the required article 2 is stored in the second container 18, the control unit 15 instructs the moving mechanism 11e of the conveying unit 11 to move the first container 17 at the first transfer position P1 to the unloading conveyor 11c and move the second container 18 at the second transfer position P2 to the unloading conveyor 11d. The first container 17 moved to the unloading conveyor 11c and the second container 18 moved to the unloading conveyor 11d are unloaded rearward in the Y direction.

[0030] (Guard) FIG. 3 is a front view, two side views, and a plan view among the six views showing the outline of the guard provided in the transfer system 1 of the present embodiment. In the present embodiment, automatic transfer in which the transfer unit 12 holds and transfers the article 2 can be executed. Therefore, as shown in FIGS. 1 to 3, a guard is provided around the transfer unit 12 to prevent a person or a part of the person from coming into contact with the transfer unit 12 from the viewpoint of safety.

[0031] (Horizontal guard part) As shown in FIGS. 1 to 3, each of the support parts 14a·14a includes a horizontal guard part 21 that partitions the transfer unit 12 and the outside thereof in the X direction. The horizontal guard part 21 includes a transparent plate 22 and a frame member 23 that holds the transparent plate 22. Thereby, it is possible to prevent a person or a part of the person from entering from the X direction and coming into contact with the transfer unit 12, and as a result, the safety of the transfer system 1 can be improved.

[0032] Furthermore, since the horizontal guard part 21 is provided on each of the support parts 14a·14a, there is no need to newly provide a guard part that partitions the transfer unit 12 and the outside thereof in the X direction outside the support parts 14a·14a in the X direction. As a result, the space saving of the transfer system 1 can be achieved.

[0033] Incidentally, since the two support portions 14a, 14a are installed adjacent to the transfer portion 12 in the X direction, they are also adjacent to the housing 11f of the transfer portion 11 located below the transfer portion 12 in the Z direction. Therefore, in the present embodiment, in the lower region of the support portion 14a, that is, in the region facing the housing 11f, the horizontal guard portion 21 is omitted. As a result, the area where the horizontal guard portion 21 is provided can be reduced. On the other hand, entry of a person or a part of a person from below the support portion 14a and contact with the transfer portion 12 can be prevented by the housing 11f. That is, the housing 11f serves as a partition between the transfer portion 12 and the outside in the X direction in the lower region of the support portion 14a.

[0034] (Front guard portion) As shown in FIGS. 1 to 3, the transfer system 1 is provided with a front guard portion 24 (terminal side partition portion) that partitions the outside on the opposite side of the transfer portion 11 with respect to the transfer portion 12 in plan view, that is, the outside on the front side in the Y direction of the transfer portion 12, and the transfer portion 12. The front guard portion 24 is connected to the two support portions 14a, 14a.

[0035] Incidentally, as shown in FIGS. 1 and 2, the transfer system 1 of the present embodiment is capable of performing both automatic transfer in which the transfer portion 12 holds and transfers the article 2 and manual transfer in which an operator holds and transfers the article 2. For this reason, a work area 25 for performing the above-described manual transfer is set between the transfer portion 12 and the front guard portion 24. That is, the front guard portion 24 is provided adjacent to the work area 25 around the work area 25.

[0036] Specifically, the front guard portion 24 includes a plurality of fixed guard portions 26 and a movable guard portion 27 connected together. The fixed guard portion 26 includes a transparent plate 31 and a frame member 32 that holds the transparent plate 31. The lower corner portion in the Z direction of the frame member 32 is fixed to the installation location of the transfer system 1 by a fixing member 26a.

[0037] The movable guard part 27 includes a fixing frame member 33 and a movable member 34 provided within the fixing frame member 33. The lower corner of the fixing frame member 33 in the Z direction is fixed to the installation location of the transfer system 1 by a fixing member 33a. The movable member 34 includes a transparent plate 35 and a frame member 36 that holds the transparent plate 35. Also, the fixed guard parts 26·26 on the rear side in the Y direction are respectively connected to the front side in the Y direction of the support parts 14a·14a.

[0038] This can prevent people from inadvertently entering the work area 25 and coming into contact with the transfer part 12. As a result, the safety of the transfer system 1 can be improved. Also, since the front guard part 24 is provided adjacent to the work area 25, an increase in the installation space of the transfer system 1 due to the provision of the front guard part 24 can be suppressed.

[0039] When the transfer system 1 is only capable of automatic transfer, the work area 25 may be set as a monitoring area for a monitor to monitor the transfer part 12. Alternatively, the work area 25 may be omitted. At this time, the front guard part 24 may be provided adjacent to the transfer part 12 on the front side in the Y direction of the transfer part 12.

[0040] (Rear guard part) As shown in FIGS. 1 to 3, the transfer system 1 is provided with rear guard parts 41·41 (conveyor side partition parts) that are adjacent to the front end in the Y direction of the conveyor part 11 in the X direction and partition the front end and the outside in the X direction thereof. The rear guard part 41 includes a transparent plate 42 and a frame member 43 that holds the transparent plate 42. The front side in the Y direction of the rear guard parts 41·41 is respectively connected (joined) to the rear side in the Y direction of the support parts 14a·14a. Also, the lower corner of the frame member 43 in the Z direction is fixed to the installation location of the transfer system 1 by a fixing member 43a. Furthermore, reinforcing members 44·45 are provided between the rear guard parts 41·41.

[0041] This can prevent a person or a part of a person from entering from the conveying unit 11 and coming into contact with the transfer unit 12, and as a result, the safety of the transfer system 1 can be improved. Further, since the rear guard portion 41 is provided adjacent to the conveying unit 11, an increase in the installation space of the transfer system 1 due to the provision of the rear guard portion 41 can be suppressed.

[0042] In addition, by providing the transparent plate 22 of the side guard portion 21, the transparent plates 31 and 35 of the front guard portion 24, and the transparent plate 42 of the rear guard portion 41 as guards, a monitor of the transfer system 1 can monitor the conveying unit 11 and the transfer unit 12 from the outside of the transfer system 1. Note that, instead of the transparent plates 22, 31, 35, and 42, guards having other shapes such as fences and nets may be used.

[0043] (Modification example) Next, a modification example of the transfer system 1 will be described with reference to FIG. 4.

[0044] FIG. 4 is a front view, a side view, and a plan view among six views showing an outline of a modification example of the camera unit and the support unit in the transfer system 1. The camera unit 13 and the support frame 14 shown in FIG. 4 are different from the camera unit 13 and the support frame 14 shown in FIGS. 1 to 3 in that lights 13c and 13d are provided on the beam member 14b, a support member 14i is added to the upper end portion of the support frame 14, and a reflector 13e is provided on the support member 14i, and the rest are the same. Thus, the lights 13c and 13d and the reflector 13e in the camera unit 13 can be arranged in various ways, and the support member 14i can be added to the support frame 14 according to the arrangement.

[0045] 〔Embodiment 2〕 Another embodiment of the present invention will be described with reference to FIG. 5.

[0046] FIG. 5 is a plan view showing an outline of the transfer equipment in the present embodiment. As shown in FIG. 5, the transfer equipment 3 includes a plurality of transfer systems 1 shown in FIGS. 1 to 3.

[0047] As described above, when a guard is provided around a picking device that performs automatic transfer work in a transfer system, the installation space of the transfer system increases. As a result, the distance between adjacent transfer systems increases.

[0048] In contrast, in the present embodiment, the plurality of transfer systems 1 are arranged side by side in the X direction such that the respective transport units 11 are substantially parallel to each other. As a result, the transfer unit 12 and the outside in the Y direction thereof are partitioned by the lateral guard portions 21 of the support portions 14a, 14a provided adjacent to the transfer unit 12, so that an increase in the distance between adjacent transfer systems 1 can be suppressed.

[0049] By the way, in a building 51 such as a logistics warehouse, generally, column members 52 that support the upper floor or ceiling project at predetermined intervals P. For this reason, from the viewpoint of improving the efficiency of transferring the articles 2, it is desirable that the number of transfer systems that can be installed at the predetermined interval P is large.

[0050] However, when a guard is provided around the picking device, the installation space of the transfer system increases. As a result, the number of transfer systems that can be installed at the predetermined interval P may decrease.

[0051] In contrast, in the present embodiment, with the direction in which adjacent column members 52, 52 are arranged being the X direction, the plurality of transfer systems 1 are arranged side by side. Thereby, an increase in the distance between adjacent transfer systems 1 in the X direction can be suppressed, so that a decrease in the number of transfer systems 1 that can be installed at the predetermined interval P can be suppressed.

[0052] 〔Special Note〕 In the above embodiment, the first container 17 and the second container 18 that accommodate the article 2 are being transported by the transport unit 11, but the present invention is not limited to this. For example, the first container 17 and the second container 18 may be omitted, and the article 2 itself may be transported by the transport unit 11.

[0053] 〔Summary〕 As described above, the transfer system according to Embodiment 1 of the present invention includes a transfer unit that conveys an article in a first direction, a transfer unit that is installed on one end side of the transfer unit and holds and transfers the article, a camera unit that is installed above the transfer unit and photographs the article, and two support units that support the camera unit, and are respectively installed in a second direction orthogonal to the first direction with respect to the transfer unit in a plan view, and two support units that partition the transfer unit and the outside in the second direction thereof.

[0054] According to the above configuration, it is possible to prevent a person or a part thereof from entering from the outside and coming into contact with the transfer unit. As a result, the safety of the transfer system can be improved. In addition, there is no need to newly provide a partition portion that partitions the transfer unit and the outside in the second direction thereof. As a result, space saving of the transfer system can be achieved.

[0055] The transfer system according to Embodiment 2 of the present invention may further include a terminal side partition portion that partitions the outside on the side opposite to the transfer unit with respect to the transfer unit in a plan view and the transfer unit in Embodiment 1, and is connected to the two support units. In this case, it is possible to prevent a person or a part thereof from entering from the outside and coming into contact with the transfer unit. As a result, the safety of the transfer system can be improved.

[0056] The transfer system according to Embodiment 3 of the present invention may be configured such that a work area for an operator to hold and transfer the article is set between the transfer unit and the terminal side partition portion in Embodiment 2. In this case, it is possible to prevent a person from inadvertently entering the work area and coming into contact with the transfer unit. As a result, the safety of the transfer system can be improved.

[0057] In the transfer system according to Aspect 4 of the present invention, in the above Aspects 1 to 3, in a plan view, two transfer-side partition portions are respectively installed adjacent to the one end in a second direction orthogonal to the first direction, and partition the one end and the outside in the second direction thereof. The transfer system may further include two transfer-side partition portions respectively connected to the two support portions. In this case, entry of a person or a part thereof from the transfer portion into contact with the transfer portion can be prevented, and as a result, the safety of the transfer system can be improved.

[0058] In the transfer system according to Aspect 5 of the present invention, in the above Aspects 1 to 4, the transfer portion includes a moving mechanism that sequentially moves a plurality of containers that accommodate the articles, and a housing that houses the moving mechanism. The housing is adjacent to the two support portions. In a region where the two support portions face each other, the partition between the transfer portion and the outside in the second direction thereof may be omitted. In this case, the area where the partition is provided can be reduced. Note that in the region where the partition is omitted, the housing serves as a partition between the transfer portion and the outside in the second direction thereof.

[0059] In the transfer system according to Aspect 6 of the present invention, in the above Aspects 1 to 5, the transfer portion may include a picking head that holds the article, and a drive portion that raises and lowers the picking head based on a captured image from the camera portion and moves the picking head in the first direction and the second direction in a plan view.

[0060] The transfer equipment according to Aspect 7 of the present invention is transfer equipment including a plurality of the transfer systems according to the above Aspects 1 to 6. In the transfer systems, a plurality of them are arranged side by side in a second direction orthogonal to the first direction in a plan view so that the respective transfer portions are substantially parallel to each other.

[0061] According to the above configuration, since the transfer portion and the outside in the second direction thereof are partitioned by the support portion, an increase in the interval between the adjacent transfer systems can be suppressed.

[0062] The transfer facility according to Aspect 8 of the present invention further includes a plurality of support members protruding at a predetermined interval in the above Aspect 7. With the direction in which the adjacent support members are arranged as the second direction, a plurality of the transfer systems may be arranged side by side in the second direction. In this case, since an increase in the interval between the transfer systems adjacent in the second direction can be suppressed, a decrease in the number of the transfer systems that can be installed at the predetermined interval can be suppressed.

[0063] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope shown in the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention.
