Summary of the Invention

Problems to be Solved by the Invention

[0004] In the heat treatment system of Patent Document 1, the lid alignment mechanism can only correct the inclination of the lid with respect to the width direction of the lid conveyor by the stopper. Therefore, there is a possibility that variations in the position of the lid in the width direction of the lid conveyor may occur. If variations in the position of the lid occur, it may become difficult to attach the lid by the downstream lid attachment mechanism.

[0005] An object of the present invention is to provide a heat treatment system capable of appropriately aligning lids conveyed by a lid conveyor.

Means for Solving the Problems

[0006] The heat treatment system according to the present invention includes a heat treatment unit (10), a heat treatment transfer conveyor (20), a lid transfer conveyor (40), and a lid alignment mechanism unit (90). The heat treatment unit can heat-treat a workpiece (8). The heat treatment transfer conveyor is provided so as to pass through the heat treatment unit and conveys a container (3) that houses the workpiece and a lid (6) attached to the container. The lid transfer conveyor conveys the lid of the container that houses the workpiece heat-treated in the heat treatment unit.

[0007] The lid alignment mechanism unit can align the lids conveyed by the lid transfer conveyor. The lid alignment mechanism unit has a stopper (91) and a width adjustment unit (92). The stopper can correct the inclination of the lid with respect to the width direction of the lid transfer conveyor by contacting the lid on the front side in the conveyance direction of the lid. The width adjustment unit can adjust the position of the lid in the width direction of the lid transfer conveyor by contacting the lid from both sides in the width direction of the lid transfer conveyor.

[0008] In the present invention, not only can the inclination of the lid with respect to the width direction of the lid transfer conveyor be corrected by the stopper of the lid alignment mechanism unit, but also the position of the lid in the width direction of the lid transfer conveyor can be adjusted by the width adjustment unit. Therefore, it is possible to appropriately align the lids conveyed by the lid transfer conveyor. In a first aspect of the present invention, the stopper has a stopper roller support portion (911) provided so as to be movable upward or downward in the vertical direction, and a stopper roller (912) provided rotatably in the stopper roller support portion and capable of abutting against the lid. In a second aspect of the present invention, a plurality of stoppers are provided in the lid conveyance direction in the lid conveyance conveyor. In a third aspect of the present invention, the lid conveyance conveyor conveys lids arranged in a plurality in the width direction of the lid conveyance conveyor. A fourth aspect of the present invention further includes a lid attachment mechanism portion (72) capable of attaching the lid conveyed by the lid conveyance conveyor to the container.

The conveying rollers 300 are rotatable in a predetermined direction by a driving device (not shown).

[0040] The container lifter 73 is provided between the adjacent conveying rollers 300 in the y-axis direction so as to be movable in the vertical upward or downward direction (z-axis direction) by a driving device (not shown).

[0041] The first support portion 701 has a claw portion 75 and a pressing portion 76. The claw portion 75 has a claw body 751 and a claw support 752. The claw body 751 is formed in a rectangular plate shape and is provided along the zy plane. The claw support 752 is formed to protrude in the horizontal direction (x-axis direction) from the lower end portion of the claw body 751. Two claw portions 75 are provided at a predetermined interval in the x-axis direction such that the claw supports 752 face each other in the x-axis direction. The two claw portions 75 are movable in the x-axis direction so as to approach each other or move away from each other. The pressing portion 76 is formed in a long plate shape. Two pressing portions 76 are provided at a predetermined interval in the y-axis direction while along the x-axis. The pressing portion 76 is reciprocally movable in the vertical direction (z-axis direction).

[0042] The rail 77 is formed in a rod shape, and both ends thereof are supported by the support portion 705. Two rails 77 are provided at a predetermined interval in the y-axis direction while along the x-axis. The first support portion 701 is provided on one of the two rails 77. The first support portion 701 is reciprocally movable in the x-axis direction along the rail 77 by a driving portion 78 supported by the upper end portion of the support portion 705.

[0043] The second support portion 702 is provided on the other of the two rails 77 and is reciprocally movable in the x-axis direction along the rail 77 by the driving portion 78. Since the second support portion 702 has the same configuration as the first support portion 701, the description thereof is omitted.

[0044] As shown in FIGS. 6 and 7, the lid conveyor 41 has a support portion 405, a roller support portion 406, a conveying roller 400, etc. The roller support portion 406 is supported by the support portion 405 installed on the floor 9. The roller support portion 406 is provided along the length direction (x-axis direction) on both sides in the width direction (y-axis direction) of the lid conveyor 41. The conveying roller 400 has a rotating shaft 401 and a support wheel 402. The configuration of the rotating shaft 401 and the support wheel 402 is the same as that of the rotating shaft 201 and the support wheel 202. The support wheels 402 are provided, for example, four in the length direction (y-axis direction) of the rotating shaft 401. A plurality of conveying rollers 400 are provided at predetermined intervals in the length direction (x-axis direction) of the lid conveyor 41. The conveying roller 400 is rotatable in a predetermined direction by a driving device (not shown).

[0045] The lid lifter 74 is provided between the adjacent conveying rollers 400 in the x-axis direction so as to be movable in the vertical upper or lower direction (z-axis direction) by a driving device (not shown).

[0046] Next, the operation of the lid removing mechanism unit 71 will be described.

[0047] When the multi-stage container 7 with a lid is conveyed by the post-treatment conveyor 32 to a position vertically above the container lifter 73, the container lifter 73 moves vertically upward from the initial position. As a result, the multi-stage container 7 with a lid moves vertically upward while being supported by the upper end portion of the container lifter 73 (see FIG. 6). Subsequently, when the two claw portions 75 of the first support portion 701 and the second support portion 702 move closer to each other, the claw support bodies 752 enter between the lid 6 and the notch portion 5 of the two multi-stage containers 7 arranged in the y-axis direction from both sides in the x-axis direction. Subsequently, when the pressing portion 76 moves vertically downward, the lid 6 is in a state where both end portions in the x-axis direction are supported by the claw support bodies 752 from vertically below, and the upper surface in the vertical direction is pressed by the pressing portion 76. Subsequently, when the container lifter 73 moves vertically downward, the containers 3 stacked in two stages also move vertically downward, and the lid 6 is removed from the container 3.

[0048] Subsequently, when the first support portion 701 and the second support portion 702 move in the -x direction along the rail 77, the lid lifter 74 moves upward in the vertical direction, and the lid 6 is supported from the lower side in the vertical direction (see FIG. 7). Subsequently, when the pressing portion 76 moves upward in the vertical direction and the two claw portions 75 of each of the first support portion 701 and the second support portion 702 move away from each other, the two lids 6 are supported by the upper end portion of the lid lifter 74. Subsequently, when the lid lifter 74 moves downward in the vertical direction, the two lids 6 are supported by the support wheels 402 of the conveying roller 400. Through the above operations, the removal of the lid 6 from the multi-stage container 7 with a lid conveyed by the post-treatment conveying conveyor 32 and the conveyance of the lid 6 to the lid conveying conveyor 41 are completed.

[0049] As shown in FIGS. 8 and 9, the elevating lifter 81 includes an elevating rail 83, a movable roller support portion 85, a conveying roller 800, etc. The elevating rail 83 is formed, for example, in a columnar shape, and a plurality of them are installed on the floor 9 along the vertical direction. The movable roller support portion 85 is provided along the x-axis direction on both sides of the elevating lifter 81 in the y-axis direction. The movable roller support portion 85 is supported by the elevating rail 83 and is provided so as to be movable upward or downward (in the z-axis direction) along the elevating rail 83 by a driving device (not shown). The conveying roller 800 has a rotating shaft 801 and a support wheel 802. The configurations of the rotating shaft 801 and the support wheel 802 are the same as those of the rotating shaft 201 and the support wheel 202. For example, four support wheels 802 are provided in the length direction (y-axis direction) of the rotating shaft 801. A plurality of conveying rollers 800 are provided at a predetermined interval in the x-axis direction of the movable roller support portion 85. The conveying roller 800 is rotatable in a predetermined direction by a driving device (not shown).

[0050] As shown in FIG. 9, guides 95 are provided on the lid conveying conveyors 41 and 42 and the lifting lifter 81. The guides 95 are provided in the vicinity of the roller support portions 406 on both sides in the width direction (y-axis direction) of the lid conveying conveyors 41 and 42, and in the vicinity of the movable roller support portions 85 on both sides in the y-axis direction of the lifting lifter 81. The guide 95 has guide rollers 951. The guide rollers 951 are formed in an annular shape from a ceramic material such as alumina, for example, and are rotatable about a rotation axis along the vertical direction (z-axis direction). A plurality of guide rollers 951 are provided in the length direction (x-axis direction) of the lid conveying conveyors 41 and 42.

[0051] Nine guide rollers 951 are provided side by side in the x-axis direction in the vicinity of the movable roller support portions 85 on both sides in the y-axis direction of the lifting lifter 81. Two guide rollers 951 located on both sides in the x-axis direction among the nine guide rollers 951 are provided at positions shifted toward the movable roller support portion 85 with respect to the other seven guide rollers 951. That is, the rotation axes of the other seven guide rollers 951 are orthogonal to a straight line L1 along the x-axis direction, and the rotation axes of the two guide rollers 951 located on both sides in the x-axis direction are separated from the straight line L1 toward the movable roller support portion 85. The rotation axes of the guide rollers 951 of the guide 95 provided on the lid conveying conveyors 41 and 42 are orthogonal to the straight line L1.

[0052] The lid conveying conveyors 41 and 42 convey the lids 6 arranged in two in the width direction (y-axis direction) of the lid conveying conveyors 41 and 42 (see FIG. 9). In the lid conveying conveyors 41 and 42 and the lifting lifter 81, the distance in the y-axis direction of the guide rollers 951 whose rotation axes are orthogonal to the straight line L1 is set to about 68 cm, for example. The lid conveying conveyors 41 and 42 and the lifting lifter 81 convey the lids 6 arranged in two in the y-axis direction in the -x direction. The guide rollers 951 rotate when they contact the outer edge portion of the lid 6 and can guide the conveyance of the lid 6. When the two lids 6 arranged in the y-axis direction contact each other and are located at the center in the y-axis direction (see FIG. 9), a gap of about 1.5 cm is formed between the guide rollers 951 and the lids 6 on both sides in the y-axis direction with respect to the two lids 6.

[0053] The lid transfer conveyor 41 is divided into the +x direction side and the -x direction side with respect to the lifting lifter 81 (see FIG. 8). The two lids 6 conveyed in the -x direction by the lid transfer conveyor 41 located on the +x direction side with respect to the lifting lifter 81 are conveyed to the transfer roller 800 of the lifting lifter 81 located at the same height as the transfer roller 400 of the lid transfer conveyor 41. Here, when the movable roller support portion 85 moves upward in the vertical direction, the two lids 6 are conveyed to the lid transfer conveyor 42 by the rotation of the transfer roller 800. On the other hand, when the movable roller support portion 85 does not move upward in the vertical direction, the two lids 6 are conveyed to the lid transfer conveyor 41 on the -x direction side with respect to the lifting lifter 81 by the rotation of the transfer roller 800.

[0054] In the present embodiment, among the nine guide rollers 951 arranged in the x-axis direction in the vicinity of the movable roller support portion 85 on both sides in the y-axis direction of the lifting lifter 81, the two guide rollers 951 located on both sides in the x-axis direction are provided at positions shifted toward the movable roller support portion 85 side with respect to the other seven guide rollers 951. Therefore, when the two lids 6 conveyed by the lid transfer conveyor 41 are conveyed to the transfer roller 800 of the lifting lifter 81, it is possible to suppress the front surface in the conveyance direction of the lid 6 from colliding with the guide roller 951 and preventing the conveyance. As a result, the lid 6 can be smoothly conveyed to the transfer roller 800.

[0055] The lid alignment mechanism unit 90 includes a stopper 91, a width adjustment unit 92, a lid lifter 93 with rollers, etc. As shown in FIGS. 10 to 12, the stopper 91 is provided on the lid conveying conveyors 41 and 42. A plurality of stoppers 91 are provided at predetermined intervals in the length direction (x-axis direction) of the lid conveying conveyors 41 and 42. The stopper 91 has a stopper roller support portion 911 and a stopper roller 912. The stopper roller support portion 911 is provided between adjacent conveying rollers 400 in the x-axis direction so as to be movable in the vertical upward or downward direction (z-axis direction) by a driving device (not shown). The stopper roller 912 is formed in a cylindrical shape from a ceramic material such as alumina, for example, and is rotatably provided at the upper end portion of the stopper roller support portion 911. Here, the stopper roller 912 is provided such that its rotation axis is along the y-axis direction. A plurality of stopper rollers 912 are provided in the y-axis direction.

[0056] When the lid 6 is conveyed by the lid conveying conveyors 41 and 42, the stopper 91 moves upward in the vertical direction from the initial position on the lower side in the vertical direction with respect to the conveying roller 400. As a result, the stopper roller 912 abuts on the lid 6 on the front side (-x direction side) in the conveying direction (-x direction) of the lid 6 (see FIGS. 10 and 11). Thereby, the front surface of the lid 6 in the conveying direction becomes parallel to the y-axis direction, and the inclination of the lid 6 with respect to the width direction (y-axis direction) of the lid conveying conveyors 41 and 42 is corrected (see FIG. 11). After the stopper 91 abuts on the lid 6, it descends and returns to the initial position. Since the stopper roller 912 is rotatably provided, it is possible to suppress wear or damage to the contact portion between the lid 6 and the stopper roller 912 when the stopper 91 descends.

[0057] The guide 95 is provided over the entire range in the length direction (x-axis direction) of the lid conveying conveyors 41 and 42 except for the positions where the stoppers 91 are provided. The guide 95 guides the conveyance of the lid 6 on the lid conveying conveyors 41 and 42, and can suppress a large displacement of the lid 6 in the y-axis direction and a large inclination of the lid 6 with respect to the y-axis direction.

[0058] As shown in FIGS. 13 and 14, the elevating lifter 82 is provided on the -x direction side with respect to the end portion on the -x direction side of the lid conveying conveyor 42. The lid conveying conveyor 41 is divided into a +x direction side and a -x direction side with respect to the elevating lifter 82. The configuration of the elevating lifter 82 is the same as that of the elevating lifter 81.

[0059] The two lids 6 conveyed in the -x direction by the lid conveying conveyor 42 located on the +x direction side with respect to the elevating lifter 82 are conveyed to the conveying roller 800 of the elevating lifter 82 located at the same height as the conveying roller 400 of the lid conveying conveyor 42. When the lid 6 is conveyed to the conveying roller 800, the movable roller support portion 85 moves downward in the vertical direction so that the conveying roller 800 becomes the same height as the conveying roller 400 of the lid conveying conveyor 41. Thereafter, the lid 6 is conveyed to the lid conveying conveyor 41 on the -x direction side with respect to the elevating lifter 82 by the rotation of the conveying roller 800. On the other hand, the two lids 6 conveyed in the -x direction by the lid conveying conveyor 41 located on the +x direction side with respect to the elevating lifter 82 are conveyed to the conveying roller 800 of the elevating lifter 82 located at the same height as the conveying roller 400 of the lid conveying conveyor 41. Thereafter, the lid 6 is conveyed to the lid conveying conveyor 41 on the -x direction side with respect to the elevating lifter 82 by the rotation of the conveying roller 800.

[0060] As shown in FIGS. 15 to 17, the width adjustment portion 92 is provided on the -x direction side with respect to the stopper 91 provided in the vicinity of the end portion on the -x direction side of the lid conveying conveyor 41. The width adjustment portion 92 has a clamping portion 921, a clamping portion support 922, and a width adjustment drive portion 923. The clamping portion 921 is formed in, for example, a rectangular plate shape. The clamping portion 921 is provided along the zx plane in the vicinity of the roller support portions 406 on both sides in the width direction (y-axis direction) of the lid conveying conveyor 41. The clamping portion support 922 is formed in, for example, a rod shape, and one end is provided so as to be connected to the surface of the clamping portion 921 on the roller support portion 406 side. The width adjustment drive portion 923 is provided on the other end side of the clamping portion support 922, and by driving the clamping portion support 922 in the y-axis direction, the two clamping portions 921 can be driven to approach each other or move away from each other in the y-axis direction.

[0061] The lid lifter 93 with rollers is provided at a position corresponding to the width alignment portion 92 in the length direction (x-axis direction) of the lid conveyor 41 (see FIGS. 15 and 16). The lid lifter 93 with rollers has a lifter roller support portion 931 and a lifter roller 932. The lifter roller support portion 931 has a first lifter roller support portion 941 and a second lifter roller support portion 942. The first lifter roller support portion 941 and the second lifter roller support portion 942 are provided between the adjacent conveyor rollers 400 in the x-axis direction so as to be movable in the vertical upward or downward direction (z-axis direction) by a driving device (not shown). The first lifter roller support portion 941 is provided on the side opposite to the second lifter roller support portion 942 with respect to the conveyor roller 400 in the x-axis direction.

[0062] The lifter roller 932 is formed in an annular shape from a ceramic material such as alumina, for example, and is rotatably provided at the upper ends of the first lifter roller support portion 941 and the second lifter roller support portion 942. Here, the lifter roller 932 is provided such that the rotation axis 201 is along the x-axis direction. A plurality of lifter rollers 932 are provided in the y-axis direction in the first lifter roller support portion 941 and the second lifter roller support portion 942.

[0063] When the lid 6 is conveyed by the lid conveyor 41, the stopper 91 moves from the initial position on the lower side in the vertical direction with respect to the conveyor roller 400 to the upper side in the vertical direction. As a result, the stopper roller 912 comes into contact with the lid 6 on the front side (-x direction side) in the conveying direction (-x direction) of the lid 6. Thereby, the front surface of the lid 6 in the conveying direction becomes parallel to the y-axis direction, and the inclination of the lid 6 with respect to the width direction (y-axis direction) of the lid conveyor 41 is corrected. Subsequently, when the lid lifter 93 with rollers moves upward in the vertical direction, the lid 6 moves to a position corresponding to the sandwiching portion 921 while being supported by the lifter roller 932 from the lower side in the vertical direction.

[0064] Subsequently, when the two clamping portions 921 are driven by the width adjustment drive unit 923 to approach each other, the two lids 6 arranged in the y-axis direction are clamped by the two clamping portions 921 from both sides in the width direction (y-axis direction) of the lid conveyor 41. Thereby, the position of the lid 6 in the width direction (y-axis direction) of the lid conveyor 41 can be adjusted. When the two lids 6 arranged in the y-axis direction are clamped by the two clamping portions 921, the lifter roller 932 that contacts the lower surface of the lid 6 in the vertical direction rotates. Thereby, the position of the lid 6 can be adjusted while suppressing wear or damage due to sliding between the lifter roller 932 and the lid 6 in the y-axis direction.

[0065] Subsequently, when the two clamping portions 921 are driven by the width adjustment drive unit 923 to move away from each other, the lid lifter 93 with rollers moves downward in the vertical direction, and the two lids 6 are placed on the conveying rollers 400. The stoppers 91 and the width adjustment portions 92 of the lid alignment mechanism unit 90 correct the inclination with respect to the y-axis direction, and the two lids 6 aligned by adjusting the positions in the y-axis direction are conveyed to the downstream lid attachment mechanism unit 72.

[0066] As shown in FIGS. 18 and 19, the lid attachment mechanism unit 72 has a container lifter 73, a lid lifter 74, a first support portion 701, a second support portion 702, a rail 77, a drive unit 78, a support portion 705, etc., similar to the lid removal mechanism unit 71. The configurations of the container lifter 73, the lid lifter 74, the first support portion 701, the second support portion 702, the rail 77, the drive unit 78, and the support portion 705 are the same as those in the lid removal mechanism unit 71.

[0067] As shown in FIG. 18, the pre-treatment conveyor 62 has conveying rollers 600. The conveying rollers 600 have a rotating shaft 601 and support wheels 602. The configurations of the rotating shaft 601 and the support wheels 602 are the same as those of the rotating shaft 201 and the support wheels 202. For example, two support wheels 602 are provided in the length direction (x-axis direction) of the rotating shaft 601. A plurality of conveying rollers 600 are provided at predetermined intervals in the length direction (y-axis direction) of the pre-treatment conveyor 62. The conveying rollers 600 are rotatable in a predetermined direction by a drive device (not shown).

[0068] Next, the operation of the lid attachment mechanism unit 72 will be described.

[0069] When the two lids 6 aligned by the lid alignment mechanism unit 90 are conveyed by the lid conveyance conveyor 41 to a position above the lid lifter 74 in the vertical direction, the lid lifter 74 moves upward in the vertical direction from the initial position. As a result, the two lids 6 move upward in the vertical direction while being supported by the upper end portion of the lid lifter 74 (see FIGS. 18 and 19). Subsequently, when the two claw portions 75 of the first support portion 701 and the second support portion 702 move closer to each other, the claw support bodies 752 enter from both sides in the x-axis direction below the lower surfaces of the two lids 6 arranged in the y-axis direction. Subsequently, when the pressing portion 76 moves downward in the vertical direction, the lids 6 are in a state where both end portions in the x-axis direction are supported by the claw support bodies 752 from below in the vertical direction, and the upper surface in the vertical direction is pressed by the pressing portion 76. Subsequently, when the lid lifter 74 moves downward in the vertical direction, the upper end portion of the lid lifter 74 is separated from the lid 6.

[0070] Subsequently, the first support portion 701 and the second support portion 702 move in the -x direction along the rail 77 and are positioned above the container lifter 73 in the vertical direction. When the two-stage stacked container 3 containing the workpiece 8 before processing is conveyed by the pre-processing conveyor 62 to a position above the container lifter 73 in the vertical direction, the container lifter 73 moves upward in the vertical direction from the initial position. As a result, the two-stage stacked container 3 moves upward in the vertical direction while being supported by the upper end portion of the container lifter 73. Subsequently, when the pressing portion 76 moves upward in the vertical direction and the two claw portions 75 of the first support portion 701 and the second support portion 702 move away from each other, the lid 6 is attached to the upper end portion of the two-stage stacked container 3 (multi-stage container 7 with a lid). Subsequently, when the container lifter 73 moves downward in the vertical direction, the two multi-stage containers 7 with lids are supported by the support wheels 602 of the conveying roller 600. Through the above operations, the attachment of the lid 6 to the container 3 conveyed by the pre-processing conveyor 62 is completed.

[0071] As described above, (1) this embodiment includes a heat treatment unit 10, a heat treatment transfer conveyor 20, a lid transfer conveyor 40, and a lid alignment mechanism unit 90. The heat treatment unit 10 can heat-treat the workpiece 8. The heat treatment transfer conveyor 20 is provided so as to pass through the heat treatment unit 10 and conveys the container 3 that houses the workpiece 8 and the lid 6 attached to the container 3. The lid transfer conveyor 40 conveys the lid 6 of the container 3 that houses the workpiece 8 heat-treated in the heat treatment unit 10.

[0072] The lid alignment mechanism unit 90 can align the lids 6 conveyed by the lid transfer conveyor 40. The lid alignment mechanism unit 90 has a stopper 91 and a width adjustment unit 92. The stopper 91 can correct the inclination of the lid 6 with respect to the width direction of the lid transfer conveyor 40 by contacting the lid 6 on the front side in the conveyance direction of the lid 6. The width adjustment unit 92 can adjust the position of the lid 6 in the width direction of the lid transfer conveyor 40 by contacting the lid 6 from both sides in the width direction of the lid transfer conveyor 40.

[0073] In this embodiment, not only can the inclination of the lid 6 with respect to the width direction of the lid transfer conveyor 40 be corrected by the stopper 91 of the lid alignment mechanism unit 90, but also the position of the lid 6 in the width direction of the lid transfer conveyor 40 can be adjusted by the width adjustment unit 92. Therefore, it is possible to appropriately align the lids 6 conveyed by the lid transfer conveyor 40.

[0074] Also, (2) in this embodiment, the lid transfer conveyor 40 is provided parallel to the heat treatment transfer conveyor 20 and has substantially the same length as the heat treatment transfer conveyor 20.

[0075] Therefore, in the lid transfer conveyor 40, a large number of lids 6 can be stocked. As a result, the number of stocked lids 6 that can be held in case of a problem increases, and the time required for recovery work can be saved. Further, by providing the lid transfer conveyor 40 and the heat treatment transfer conveyor 20 in parallel, the installation space of the heat treatment system 1 can be reduced.

[0076] Further, (3) in this embodiment, a plurality of stoppers 91 are provided in the conveyance direction of the lid 6. Therefore, the inclination of the lid 6 can be corrected a plurality of times during the conveyance path of the lid 6.

[0077] Note that the plate-shaped lid 6 may be distorted when heated in the heat treatment unit 10. Further, in this embodiment, since the lid conveyance conveyor 40 is provided parallel to the heat treatment conveyance conveyor 20 and has substantially the same length as the heat treatment conveyance conveyor 20, the conveyance path of the lid conveyance conveyor 40 becomes relatively long. Therefore, there is a risk that the lid 6 may meander or tilt during the conveyance path. In this embodiment, since a plurality of stoppers 91 are provided in the conveyance direction of the lid 6, the inclination of the lid 6 can be corrected even at the end of the conveyance path of the lid conveyance conveyor 40.

[0078] Further, (4) in this embodiment, the lid conveyance conveyor 40 conveys the lids 6 arranged in the width direction of the lid conveyance conveyor 40. Therefore, in the lid conveyance conveyor 40, a large number of lids 6 can be stocked, and a large number of lids 6 can be conveyed within a predetermined time.

[0079] Further, (5) this embodiment further includes a lid attachment mechanism unit 72. The lid attachment mechanism unit 72 can attach the lid 6 conveyed by the lid conveyance conveyor 40 to the container 3. In this embodiment, since a lid alignment mechanism unit 90 capable of aligning the lids 6 conveyed by the lid conveyance conveyor 40 is provided, the lid attachment mechanism unit 72 can attach the aligned lids 6 to the container 3. Therefore, it is possible to suppress the incompleteness of attaching the lid 6 to the container 3 and attach the lid 6 to the container 3 with high accuracy.

[0080] Further, (6) in this embodiment, the lid attachment mechanism unit 72 includes a lid lifter 74, a claw portion 75, and a pressing portion 76. The lid lifter 74 can lift the lid 6 from the lid conveyance conveyor 40. The claw portion 75 can support the lid 6 lifted by the lid lifter 74 from the lower side in the vertical direction. The pressing portion 76 can press the lid 6 supported by the claw portion 75 from the upper side in the vertical direction.

[0081] The lid attachment mechanism portion 72 can stably hold the lid 6 by the claw portion 75 and the pressing portion 76. Therefore, it is possible to suppress the failure in attaching the lid 6 to the container 3 and to accurately attach the lid 6 to the container 3.

[0082] (Other embodiments) In other embodiments, the lid conveyance conveyor does not have to be provided in parallel with the heat treatment conveyance conveyor. Also, the lid conveyance conveyor does not have to be provided to have substantially the same length as the heat treatment conveyance conveyor.

[0083] Also, in the above-described embodiment, an example in which a plurality of stoppers are provided in the conveyance direction of the lid has been shown. In contrast, in other embodiments, a plurality of stoppers do not have to be provided in the conveyance direction of the lid.

[0084] Also, in the above-described embodiment, an example in which the lid conveyance conveyor conveys the lids arranged in two in the width direction of the lid conveyance conveyor has been shown. In contrast, in other embodiments, the lid conveyance conveyor may convey the lids arranged in one or three or more in the width direction of the lid conveyance conveyor according to the number of lids to be conveyed within a predetermined time or the like.

[0085] Also, in other embodiments, the length of the heat treatment section may be appropriately changed according to the amount of the workpiece to be processed and other conditions. Also, the lengths of the heat treatment conveyance conveyor and the lid conveyance conveyor may be appropriately changed according to the length of the heat treatment section.

[0086] Also, in other embodiments, the dimensions of the container and the lid may be appropriately changed according to the amount of the workpiece to be processed and other conditions.

[0087] Also, in the above-described embodiment, an example in which each member and part of the heat treatment system are arranged along each axial direction in the xyz coordinates has been shown. In contrast, in other embodiments, each member and part of the heat treatment system do not have to be arranged along each axial direction in the xyz coordinates.

[0088] Thus, the present disclosure is not limited to the above-described embodiments and can be implemented in various forms without departing from the gist thereof.
