Mode for Carrying Out the Invention

[0009] Hereinafter, an embodiment will be described with reference to the drawings. In the following description, the terms "first" and "second" are merely for distinguishing between the same types of configurations and the like, and do not mean superiority or inferiority of each configuration

[0010] The production facility 1 shown in Fig. 1 is a facility provided, for example, inside a factory for producing products through processing, assembly, inspection, etc. As shown in Fig. 1, the production facility 1 can be used individually or with multiple units connected. The production facility 1 can produce products automatically or semi-automatically. "Automatically" means that in the production of products using the production facility 1, there is no operation by an operator, i.e., a human. "Semi-automatically" means that in the production of products using the production facility 1, there is a partially human operation. In the following description, the installation surface side of the production facility 1, i.e., the vertically downward side, is defined as the lower side of the production facility 1, and the side opposite to the installation surface, i.e., the vertically upward side, is defined as the upper side of the production facility 1. Also, the left side of the paper in Fig. 2 is defined as the front side of the production facility 1, and the right side of the paper in Fig. 2 is defined as the rear side of the production facility 1. Furthermore, the direction orthogonal to the vertical and front-rear directions, i.e., the depth direction of the paper in Fig. 2, is defined as the left-right direction of the production facility 1.

[0011] As shown in Figs. 2 and 3, the production facility 1 includes a first device 10, a second device 20, and a position adjustment device 30. The first device 10 and the position adjustment device 30 are installed on the installation surface, which is the working floor surface inside the factory. In the production facility 1, the first device 10 is arranged to face the second device 20 and the position adjustment device 30 in the front-rear direction. Note that the first device 10 may be configured to be detachably attached to the position adjustment device 30.

[0012] The first device 10 has a frame body 11, a transfer table 12, and a cover body 13. The frame body 11 has vertical members 111 and horizontal members 112 and is formed in a substantially rectangular outer shape. The vertical members 111 and the horizontal members 112 are, for example, made of square steel pipes. The vertical members 111 extend in the vertical direction, and a plurality of them are provided at intervals in the front-rear direction. The horizontal members 112 extend in the front-rear direction and are provided at the upper and lower parts of the plurality of vertical members 111, respectively. The frame body 11 is configured as a pair on the left and right. The pair of frame bodies 11 are connected by a bridging member (not shown) and integrated. The frame body 11 is supported on the installation surface via legs 113. The legs 113 are, for example, composed of level adjusters, etc., and a plurality of them are provided. In this case, the vertical position and posture of the frame body 11 are adjusted by the legs 113.

[0013] The transfer table 12 is installed on a pair of frame bodies 11. The transfer table 12 is formed, for example, in a substantially rectangular plate shape and constitutes a horizontal surface. Here, the term "horizontal" does not mean a completely horizontal and flat surface, but rather a surface that can be considered horizontally practical. The transfer table 12 functions as a first device side mounting surface. The transfer table 12 is detachably mounted with the products during production. The cover body 13 is configured in a box shape so as to cover the upper surface 12a of the transfer table 12. An accommodation space is formed inside the cover body 13.

[0014] The second device 20 is configured to be detachable from the first device 10 and the position adjustment device 30. The second device 20 is located behind the first device 10 and above the position adjustment device 30 when attached to the first device 10 and the position adjustment device 30. As shown in FIG. 1, the second device 20 is configured to be transportable by the transport device 90 when removed from the first device 10 and the position adjustment device 30. The transport device 90 can be manually moved within the factory by an operator. That is, the second device 20 can be attached to and detached from any first device 10 and position adjustment device 30 arranged in the factory by being transported by the transport device 90.

[0015] The second device 20 has a support frame body 21, a workbench 22, a connecting plate 23, and a lifting mechanism 24. The support frame body 21 constitutes the main body of the second device 20 and is configured in a pair on the left and right. The vertical dimension of the support frame body 21 is smaller than the vertical dimension of the frame body 11 of the first device 10. The support frame body 21 has vertical members 211 and horizontal members 212 and is formed in a substantially rectangular outer shape. The vertical members 211 and the horizontal members 212 are made of, for example, square steel pipes.

[0016] The vertical members 211 extend in the vertical direction, and a plurality of them are provided at intervals in the front-rear direction. A closing plate 213 is provided at the lower part of the vertical member 211. The closing plate 213 is made of, for example, metal and closes the lower opening of the vertical member 211. The horizontal members 212 extend in the front-rear direction and are provided at the upper and lower parts of the plurality of vertical members 211 respectively. The support frame body 21 is configured as a pair on the left and right. The pair of support frame bodies 21 are connected by an intermediate member 214 and integrated.

[0017] The workbench 22 is installed on the pair of support frame bodies 21. The workbench 22 is formed, for example, in a substantially rectangular plate shape that is long in the front-rear direction and constitutes a horizontal surface. The workbench 22 forms a plane parallel to the transfer table 12. The workbench 22 functions as a second device side attachment surface. In a state where the second device 20 is attached to the first device 10, the workbench 22 and the transfer table 12 are separated in the front-rear direction. Also, in a state where the second device 20 is attached to the first device 10, the height positions of the upper surface 22a of the workbench 22 and the upper surface 12a of the transfer table 12 are substantially the same. Although not shown in detail, the workbench 22 can transfer the products in production placed on the transfer table 12, for example, through the opening formed in the cover body 13. That is, the transfer table 12 and the workbench 22 are configured to be able to transfer products. The workbench 22 is, for example, for performing processing, assembly, inspection, etc. of products. On the workbench 22, devices (not shown) for performing processing, assembly, inspection, etc. of products are installed. A covering member 221 configured in a box shape is installed on the workbench 22 so as to cover the upper surface 22a of the workbench 22.

[0018] As shown in FIGS. 2 and 3, the connecting plate 23 is provided below the support frame body 21. The connecting plate 23 is arranged at a predetermined interval from the support frame body 21. The connecting plate 23 is made of, for example, metal and is composed of a substantially rectangular plate-shaped member. The lifting mechanism 24 is for changing the relative position in the vertical direction of the workbench 22 with respect to the installation surface. A plurality of lifting mechanisms 24 are provided between the support frame body 21 and the connecting plate 23. The plurality of lifting mechanisms 24 are respectively provided between the lower part of the vertical member 211, that is, between the closing plate 213 and the connecting plate 23.

[0019] As shown in FIG. 4, the lifting mechanism 24 can be configured to include a jack bolt 241 and a plurality of nuts 242. The plurality of nuts 242 are attached to the jack bolt 241. Then, the plurality of nuts 242 are respectively arranged in contact with the closing plate 213 or the connecting plate 23. In this case, through holes (not shown) are formed in the closing plate 213 and the connecting plate 23 at positions corresponding to the lifting mechanism 24. The through holes are formed to be able to insert the jack bolt 241. By rotating the plurality of nuts 242 with respect to the jack bolt 241, an operator can adjust the vertical position of the workbench 22.

[0020] The position adjusting device 30 detachably supports the second device 20 from below. The position adjusting device 30 can be configured to include an extension member 31, a facing member 32, and a support member 33. The extension member 31 is, for example, a member having a substantially rectangular cross section and extends along the front-rear direction. The extension members 31 are configured in a pair on the left and right. The extension member 31 is in contact with the lower surface of the connecting plate 23 in a state where the second device 20 is attached to the position adjusting device 30. The width dimension and the length dimension of the extension member 31 are set to be substantially the same as the width dimension and the length dimension of the connecting plate 23.

[0021] As shown in FIGS. 3 and 4, the connecting plate 23 and the extension member 31 are detachably attached by a fastening member 311, such as a cap screw. The fastening member 311 is arranged, for example, near the lifting mechanism 24. In this case, insertion holes (not shown) are formed in the connecting plate 23 and the extension member 31 at positions corresponding to the locations where the fastening member 311 is provided. The inner surface of the insertion hole of the connecting plate 23 is provided with female screw processing that can be fitted with the shaft portion of the fastening member 311 that has male screw processing. The insertion hole of the extension member 31 is configured to be able to insert the shaft portion of the fastening member 311. Note that the inner surface of the insertion hole of the extension member 31 may be provided with female screw processing. By attaching the fastening member 311 to the extension member 31 through the connecting plate 23, an operator can connect the second device 20 to the position adjusting device 30. On the other hand, by removing the fastening member 311 from the extension member 31, an operator can release the connection between the second device 20 and the position adjusting device 30.

[0022] The facing member 32 is provided at the lower part of the extending member 31. The facing member 32 is composed of a substantially rectangular flat plate and constitutes the bottom surface of the position adjusting device 30. As shown in FIG. 3, a horizontal cross member 34 is provided on the facing member 32. The horizontal cross member 34 is provided on the rear side of the facing member 32 and rises upward from the facing member 32. The horizontal cross member 34 extends in the left-right direction between the pair of extending members 31. The support member 33 is provided on the facing member 32 and is placed on the installation surface. The support member 33 is composed of, for example, a level adjuster or the like, and a plurality of support members 33 are provided. The vertical position and posture of the extending member 31 and the facing member 32 with respect to the installation surface are adjusted by the support member 33.

[0023] Before attaching the second device 20 to the position adjusting device 30, the operator operates the support member 33 to preliminarily adjust the height position of the extending member 31 so that the heights of the upper surface 12a of the transfer table 12 of the first device 10 and the upper surface 22a of the work table 22 of the second device 20 are generally aligned. Also, before attaching the second device 20 to the position adjusting device 30, the operator adjusts the height position of the second device 20 using the elevating mechanism 24. After that, when it is necessary to adjust the height between the upper surface 12a of the transfer table 12 and the upper surface 22a of the work table 22 after attaching the second device 20 to the position adjusting device 30, the operator operates the support member 33 to adjust the vertical position of the extending member 31 with respect to the installation surface. In this way, the height positions of the first device 10 and the second device 20 can be adjusted. Note that, with the second device 20 attached to the position adjusting device 30, the operator may adjust the height of the second device 20 using the elevating mechanism 24. In this case, the elevating mechanism 24 changes the vertical relative position with respect to the position adjusting device 30. Then, the second device 20 can adjust its vertical position with respect to the installation surface while being supported by the position adjusting device 30. Also, the method for adjusting the height positions of the first device 10 and the second device 20 is not limited to this.

[0024] Next, with reference to FIGS. 5 to 8 as well, the attachment and detachment between the first device 10 and the second device 20 will be described in detail. As shown in FIG. 5, the first device 10 has a restricting portion 14. The second device 20 has a contact portion 25. The restricting portion 14 and the contact portion 25 cooperate with each other to define the positions of the first device 10 and the second device 20 in the horizontal direction, that is, the front-rear direction and the left-right direction. The restricting portion 14 restricts the movement of the second device 20 toward the first device 10. As shown in FIG. 5, the restricting portion 14 is provided on the rear side of the carrier 12, and a plurality of, in this case two, are provided near the end portions on both the left and right sides. The restricting portion 14 is attached to the carrier 12 by, for example, a screw member or the like. The rear end of the restricting portion 14 protrudes rearward beyond the rear end of the carrier 12.

[0025] The restricting portion 14 is configured to have a substantially L-shaped cross section. In this case, as shown in FIG. 6 and the like, the restricting portion 14 has a standing wall portion 141 and a flat plate portion 142. The standing wall portion 141 is provided on the upper surface 12a of the carrier 12 and is configured to extend upward. As shown in FIG. 6 and the like, the standing wall portion 141 has a through hole 141a formed therein. The through hole 141a is formed to penetrate the standing wall portion 141 in the thickness direction. The through hole 141a is formed as, for example, a long hole.

[0026] The flat plate portion 142 is connected to the upper end of the standing wall portion 141 and extends in the front-rear direction. The flat plate portion 142 has a guide portion 142a and a flat plate portion side through hole 142b. The guide portion 142a and the flat plate portion side through hole 142b are located above the workbench 22 in a state where the second device 20 is supported by the position adjusting device 30. The guide portion 142a is formed at the rear end of the flat plate portion 142 and is formed as a V-groove. The flat plate portion side through hole 142b is formed to penetrate the flat plate portion 142 in the thickness direction.

[0027] In this embodiment, as shown in FIG. 8, the workbench 22 has a workbench-side through hole 22b. The workbench-side through hole 22b is formed to penetrate the workbench 22 in the thickness direction. The workbench-side through hole 22b faces the flat plate portion-side through hole 142b in a state where the second device 20 is attached to the first device 10. The flat plate portion-side through hole 142b and the workbench-side through hole 22b are configured such that the pin member 41 can be inserted therethrough. The pin member 41 is composed of, for example, a pin with a head.

[0028] The contact portions 25 are provided on the front side of the workbench 22, and in this case, a plurality (two in this case) are provided near the end portions on both the left and right sides. The contact portions 25 are arranged at positions corresponding to the restricting portions 14. The contact portions 25 are provided at positions that overlap the restricting portions 14 in the front-rear direction in a state where the second device 20 is supported by the position adjusting device 30. The contact portions 25 are attached to the workbench 22 by, for example, a screw member or the like.

[0029] The contact portion 25 has a base portion 251, a protruding portion 252, and a mounting hole 253. The thickness dimensions of the base portion 251 and the protruding portion 252 (in this case, the dimensions in the front-rear direction) are set to be the same. The base portion 251 is provided on the upper surface 22a of the workbench 22 and is composed of a block-shaped member that is long in the left-right direction. The protruding portion 252 extends upward from the base portion 251. The protruding portion 252 has, for example, an oval cross-section, and its front and rear surfaces are flat. The protruding portion 252 is arranged at a position that overlaps the guide portion 142a in the front-rear direction (i.e., within the region of the guide portion 142a) in a state where the second device 20 is supported by the position adjusting device 30. The protruding portion 252 is configured to be movable along the guide portion 142a toward the first device 10 side (i.e., forward). The upper end of the protruding portion 252 is located above the upper surface of the flat plate portion 142 (i.e., above the upper surface of the restricting portion 14).

[0030] The mounting hole 253 is formed to penetrate the contact portion 25 in the thickness direction. The mounting hole 253 is formed, for example, at a position straddling the base portion 251 and the protruding portion 252. In a state where the second device 20 is supported by the position adjusting device 30, the mounting hole 253 faces the through hole 141a of the restricting portion 14. In the present embodiment, the inner surface of the mounting hole 253 is subjected to female screw processing. As shown in FIG. 7 and the like, the mounting hole 253 is detachably attached to the connecting member 42 via the through hole 141a. The connecting member 42 is constituted by, for example, a hexagonal bolt.

[0031] As the connecting member 42 is screwed into the mounting hole 253, the contact portion 25 moves forward along the guide portion 142a. That is, by screwing the connecting member 42 into the mounting hole 253, the vertical and horizontal positions of the workbench 22 with respect to the transfer table 12 can be defined. In this way, with the contact portion 25 in contact with the guide portion 142a, the contact portion 25 and the restricting portion 14 are integrally connected by the connecting member 42, whereby the second device 20 is attached to the first device 10. Then, as described above, in a state where the second device 20 is attached to the first device 10, the position of the second device 20 with respect to the first device 10 is ensured by inserting the pin member 41 through the flat plate portion side through hole 142b and the workbench side through hole 22b. On the other hand, when the pin member 41 is removed from the flat plate portion side through hole 142b and the workbench side through hole 22b and the connection between the connecting member 42 and the mounting hole 253 is released, the second device 20 is removed from the first device 10.

[0032] Next, with reference to FIGS. 9 to 14 as well, the conveyance of the second device 20 by the conveyance device 90 will be described in detail. In the following description, the front-rear direction of the conveyance device 90 is described as being the same as the front-rear direction of the production facility 1. The conveyance device 90 can be configured to include a vehicle body 91, a gripping portion 92, a transfer mechanism 93, a contact body 94, a receiving device 95, and a conveyance device side connecting portion 96. The vehicle body 91 constitutes the main body of the conveyance device 90. The vehicle body 91 has a base body 911, a receiving portion 912, a plate surface member 913, side plates 914, and a pedestal 915. The base body 911 is disposed at a position facing the installation surface and constitutes the bottom surface of the vehicle body 91. The base body 911 is configured as a substantially rectangular frame body by combining, for example, square steel pipes. A plurality of wheels 911a are attached to the base body 911. The wheels 911a are configured as, for example, rubber tires and are rotatable with respect to the base body 911.

[0033] The receiving portion 912 is provided near the rear end of the base body 911. The receiving portion 912 is configured by combining, for example, square steel pipes. Both ends of the receiving portion 912 rise upward from the base body 911 and are bent at a substantially right angle and extend in the left-right direction. A plurality of wheels 912a are attached to the receiving portion 912. The wheels 912a are configured as, for example, rubber tires and are rotatable with respect to the receiving portion 912. The outer diameter of the wheels 912a is larger than the outer diameter of the wheels 911a.

[0034] The plate surface member 913 is attached to the base body 911 via a height adjustment portion 916. The height adjustment portion 916 is configured to include, for example, a jack bolt and a nut, and while supporting the plate surface member 913, it is configured to be able to adjust the vertical position of the plate surface member 913 with respect to the base body 911. The operator can change the vertical position of the plate surface member 913 with respect to the base body 911 by operating the height adjustment portion 916. The plate surface member 913 is, for example, a plate-shaped member made of metal with a plurality of openings 913a formed therein and is perforated.

[0035] The side plate 914 is provided so as to rise upward from the plate surface member 913. The side plate 914 is composed of, for example, a thin plate-like member and extends along the side of the plate surface member 913. The side plate 914 is for guiding the second device 20 in the front-rear direction when inserting and removing the second device 20 from the conveying device 90. The pedestals 915 are provided, for example, in plural at intervals in the front-rear direction near the center of the plate surface member 913. The pedestals 915 can be composed of, for example, a combination of metal members. The pedestals 915 support the support plate 931 of the transfer mechanism 93 from below.

[0036] The gripping portion 92 is a portion that an operator grips when moving the conveying device 90. The gripping portion 92 is, for example, configured in a portal shape as a whole and is attached to the upper surface of the receiving portion 912. The vicinity of the upper end of the gripping portion 92 is formed to be inclined in a direction away from the vehicle body 91 as it goes upward.

[0037] The transfer mechanism 93 is for transferring the second device 20 when inserting and removing the second device 20 with respect to the conveying device 90. The transfer mechanism 93 can be configured to include a support plate 931, a rotating shaft 932, an operation portion 933, a ball screw 934, a linear guide 935, and a mounting table 936. The support plate 931 is, for example, a plate-like member made of metal and has a plurality of openings 931a formed therein and is perforated. The support plate 931 constitutes the bottom surface of the transfer mechanism 93. The support plate 931 is supported from below by the receiving portion 912 and the pedestals 915. The rotating shaft 932 is rotatably supported by bearings (not shown) provided at the front end and the rear end of the support plate 931. An operation portion 933 is attached to the tip of the rotating shaft 932. The operation portion 933 is configured to be rotatable around the rotating shaft 932. The operation portion 933 is provided on the rear side of the vehicle body 91 and receives the operation of the operator.

[0038] The ball screw 934 converts the rotational motion of the operation unit 933 into linear motion. The ball screw 934 functions as a drive source for the linear guide 935. The linear guide 935 includes a guide rail 935a and a slider 935b. The guide rail 935a is made of, for example, all-metal, and is configured with a substantially rectangular cross-section. The guide rail 935a is placed on the support plate 931, and is configured in a pair on the left and right along the longitudinal direction of the support plate 931, in this case, the front-rear direction.

[0039] The slider 935b is made of, for example, metal, and is formed with a substantially U-shaped cross-section. The slider 935b is fitted from above so as to straddle the guide rail 935a. The slider 935b is reciprocally movable along the longitudinal direction of the guide rail 935a. The mounting table 936 is configured by, for example, a substantially rectangular plate member. The mounting table 936 is located above the ball screw 934 and the linear guide 935, and is attached to the ball screw 934 and the slider 935b.

[0040] As shown by the black arrow in FIG. 9, the slider 935b and the mounting table 936 are reciprocally movable along the guide rail 935a in response to the drive of the ball screw 934 based on the operation on the operation unit 933. In this case, for example, when the operation unit 933 is rotated clockwise, the slider 935b and the mounting table 936 move rearward, while when the operation unit 933 is rotated counterclockwise, the slider 935b and the mounting table 936 move forward.

[0041] The contact body 94 is provided near the rear end of the mounting table 936. The contact body 94 is configured to have a wall surface 941 that rises upward from the mounting table 936 and extends in the left - right direction. A tip member 942 is attached to the wall surface 941. The tip member 942 is formed to protrude rearward from the wall surface 941. The receiving device 95 is provided near the rear end of the support plate 931. The receiving device 95 faces the contact body 94 in the front - rear direction, that is, in the traveling direction of the mounting table 936. The receiving device 95 has a wall surface 951 that rises upward from the support plate 931 and extends in the left - right direction. A buffer mechanism 952 is provided on the wall surface 951. The buffer mechanism 952 is configured to include, for example, a coil spring and a shock absorber, and protrudes forward from the wall surface 951. The buffer mechanism 952 is arranged to face the tip member 942.

[0044] Also, as shown in FIGS. 3, 11, and 12, the second device 20 has a second device side connecting portion 26. The second device side connecting portion 26 is provided on the side opposite to the side attached to the first device 10, in this case, on the rear side. In the present embodiment, the second device side connecting portion 26 is provided on the rear surface of the rear vertical member 211a located on the rear side among the vertical members 211 that constitute the support frame body 21. The second device side connecting portion 26 is connected via a connecting jig 50 to the conveying device 90. In this case, as shown in FIGS. 11 and 12, the second device side connecting portion 26 is connected via the connecting jig 50 to the conveying device side connecting portion 96.

[0045] As shown in FIG. 12, the second device side connecting portion 26 has an attachment surface 261 and a groove forming member 262. The attachment surface 261 is fixed to the rear surface of the rear vertical member 211a. The attachment surface 261 is constituted by, for example, a rectangular plate-shaped member that is long in the vertical direction. The groove forming member 262 is provided behind the attachment surface 261. The groove forming member 262 is formed, for example, with a substantially L-shaped cross section. A space Ss that is open toward the inside of the second device 20 is formed by the attachment surface 261 and the groove forming member 262.

[0046] The connecting jig 50 is made of, for example, metal and is used to connect the second device 20 and the transfer device 90. The connecting jig 50 connects the second device 20 and the transfer device 90 by partially accommodating itself in the space Ss of the second device side connecting portion 26 and the space Sh of the transfer device side connecting portion 96. As shown in FIG. 13, the connecting jig 50 has a jig body 51, a handle 52, and a convex portion 53. The jig body 51 is formed, for example, in a substantially plate shape. The thickness of the jig body 51 is slightly smaller than the dimensions in the front-rear direction of the space Ss and the space Sh. The jig body 51 is accommodated in the space Ss and the space Sh when the second device 20 and the transfer device 90 are connected by the connecting jig 50.

[0047] The handle 52 is located at the upper part of the jig body 51. The handle 52 is the part that an operator grips when operating the connecting jig 50. The handle 52 is formed, for example, with a substantially rectangular appearance. The handle 52 has a handle opening 521 formed therein. The handle opening 521 is formed in a substantially rectangular shape penetrating the handle 52 in the thickness direction. The operator can grasp the handle 52 with fingers inserted into the handle opening 521.

[0048] The convex portion 53 is provided protruding from the jig body 51. The convex portion 53 is formed, for example, in a substantially rectangular shape extending in the vertical direction. As shown in FIG. 12, when the connecting jig 50 is attached to the second device 20 and the transfer device 90, the convex portion 53 is disposed between the second device side connecting portion 26 and the transfer device side connecting portion 96. The operator inserts the connecting jig 50 from above the space Ss of the second device side connecting portion 26 and the space Sh of the transfer device side connecting portion 96 with the second device side connecting portion 26 and the transfer device side connecting portion 96 aligned in the front-rear direction, thereby connecting the second device 20 and the transfer device 90 by the connecting jig 50. On the other hand, the operator pulls out the connecting jig 50 from above the space Ss of the second device side connecting portion 26 and the space Sh of the transfer device side connecting portion 96 to release the connection between the second device 20 and the transfer device 90 by the connecting jig 50. The convex portion 53 functions as a guide when inserting or pulling out the connecting jig 50 into / from the second device side connecting portion 26 and the transfer device side connecting portion 96.

[0049] When performing the transfer operation of the second device 20, the operator executes each step shown in steps S11 to S14 of FIG. 14. Hereinafter, the description will be made assuming that the second device 20 is transferred from the state in which the first device 10, the second device 10, and the position adjustment device 30 are attached. First, in step S11, the operator moves the transfer device 90 to the rear of the production facility 1 so that the second device side connection portion 26 and the transfer device side connection portion 96 are aligned in the front-rear direction. Next, in step S12, the operator inserts a plurality of connection jigs 50 between the second device side connection portion 26 and the transfer device side connection portion 96, respectively.

[0050] In step S13, the operator disconnects the connection between the second device 20 and the first device 10 and the position adjustment device 30. Specifically, regarding the disconnection of the connection between the second device 20 and the first device 10, the operator removes the pin member 41 from the flat plate portion side through hole 142b and the workbench side through hole 22b, and disconnects the connection between the connecting member 42 and the mounting hole 253. In addition, regarding the disconnection of the connection between the second device 20 and the position adjustment device 30, the operator removes the fastening member 311 from the extension member 31 to disconnect the connection between the second device 20 and the position adjustment device 30.

[0051] Next, in step S14, the operator rotates the operation portion 933 of the transfer device 90 clockwise to pull the second device 20 connected to the transfer device side connection portion 96 via the connection jig 50 toward the front side, that is, the rear side. In this case, the lower surface of the connecting plate 23 of the second device 20 slides rearward on the plate member 913 of the transfer device 90, so that the second device 20 moves rearward. When there is a step due to the non-matching of the height between the lower surface of the connecting plate 23 of the second device 20 and the plate member 913, the operator operates the height adjustment portion 916 before pulling in the second device 20 to adjust the vertical position of the plate member 913 with respect to the base body 911. The operator rotates the operation portion 933, for example, until the contact body 94 contacts the receiving device 95. Thereby, the second device 20 can be stably placed on the transfer device 90. Then, in step S15, the operator operates the gripping portion 92 to move the transfer device 90 to transfer the second device 20 to a predetermined position.

[0052] In addition, to attach the second device 20 placed on the transfer device 90 to the first device 10 and the position adjustment device 30, the reverse procedure of steps S12 to S14 may be performed. That is, the operator rotates the operation unit 933 counterclockwise to push the second device 20 forward, i.e., to the side opposite to the front side. Next, the operator connects the connecting member 42 to the mounting hole 253, attaches the pin member 41 to the through-hole 142b on the flat plate side and the through-hole 22b on the workbench side, and attaches the fastening member 311 to the extending member 31. Thereby, the second device 20, the first device 10, and the position adjustment device 30 are connected. Then, the operator pulls out each of the plurality of connecting jigs 50 from between the second device side connecting portion 26 and the transfer device side connecting portion 96.

[0053] Also, since the weight of the second device 20 is greater than the weight of the transfer device 90, if the second device 20 is inserted or removed while the second device 20 is connected to the transfer device 90, the transfer device 90 may move in the front-rear direction. Therefore, in the transfer operation of the second device 20, a configuration using the connection assist device 60 may be adopted. As shown in FIG. 15, the connection assist device 60 is configured to be lockable to the cross member 34 of the position adjustment device 30 and the base body 911 of the transfer device 90. That is, the transfer device 90 can be connected to the position adjustment device 30 fixed to the installation surface via the connection assist device 60. By using the connection assist device 60 in this way, when the second device 20 is inserted or removed with respect to the transfer device 90, the transfer device 90 can be prevented from moving in the front-rear direction. Therefore, the safety of the transfer operation of the second device 20 can be improved.

[0054] According to the embodiments described above, the production facility 1 is for producing products.

According to this, the attachment and detachment between the first device 10 and the second device 20 can be performed with a simple configuration. Thereby, the layout of the production facility 1 can be easily changed.

[0057] The restricting portion 14 has a guide portion 142a formed by a V-groove. The contact portion 25 is movable toward the first device 10 along the guide portion 142a. According to this, the attachment position of the second device 20 with respect to the first device 10 can be defined without increasing the number of parts.

[0058] The second device 20 has a lifting mechanism 24. The lifting mechanism 24 changes the vertical relative position with the position adjusting device 30. According to this, the height position of the second device 20 supported by the position adjusting device 30 can be adjusted by the lifting mechanism 24. Thereby, the positioning of the second device 20 can be efficiently performed. As a result, the layout of the production facility 1 can be easily changed.

[0059] The second device 20 has a second-device-side connecting portion 26. The second-device-side connecting portion 26 is provided on the side opposite to the side attached to the first device 10, and is connected via a connecting jig 50 to a transfer device 90 movable on the installation surface. According to this, by making the second device 20 that constitutes a part of the production facility 1 transportable by the transfer device 90, the layout of the production facility 1 can be easily changed.
