DETAILED DESCRIPTION OF THE INVENTION

[0009] (Embodiment 1) 1 and 2 show a component mounting apparatus 1 according to a first embodiment of the present invention. The component mounting apparatus 1 is an apparatus for manufacturing a mounted board by mounting components BH on a board KB, and includes a tray feeder 2 (first equipment) which is a type of component supply unit that supplies the components BH, and a main body 3 (second equipment) that receives the components BH supplied by the tray feeder 2 and mounts them on the board KB.

[0010] 2, the main body 3 includes a base 11, a board transport conveyor 12, a mounting head 13, and a head moving mechanism 14. The board transport conveyor 12 is provided on the base 11 and transports the board KB in a horizontal direction. The board transport conveyor 12 loads, positions, and transports the board KB. For the sake of convenience in the first embodiment, the transport direction of the board KB by the board transport conveyor 12 is defined as the X direction (the left-right direction as seen from the worker OP), the horizontal direction perpendicular to the X direction is defined as the Y direction (the front-to-back direction as seen from the worker OP), and the up-down direction is defined as the Z direction. Furthermore, the back side of the Y direction as seen from the worker OP is defined as the front, and the front side as seen from the worker OP is defined as the rear.

[0011] The tray feeder 2 supplies components BH by positioning a component storage unit 15 containing the components BH at a predetermined component supply height. The mounting head 13 is equipped with a nozzle 13N extending downward, and the component BH is picked up by the lower end of the nozzle 13N. The head movement mechanism 14 is, for example, an XY table, and moves the mounting head 13 horizontally.

[0012] 2, tray feeder 2 includes a cart 21, a magazine storage section 22, a drawer table 23, and a table lifting section 24. Cart 21 is movable on floor surface FL by means of a plurality of wheels 21a, and is coupled to base 11 by approaching it from behind.

[0013] 2, the magazine storage section 22 is installed at the rear of the carriage 21. A plurality of magazines 25 are stored inside the magazine storage section 22. A plurality of component storage units 15 are held in each magazine 25, lined up in the vertical direction. The component storage units 15 inside the magazine 25 can be pulled out from the front side of the magazine 25 to the outside of the magazine 25, and the component storage units 15 outside the magazine 25 can be stored inside the magazine 25 from the front side of the magazine 25.

[0014] The component storage unit 15 consists of a tray 15a and a pallet 15b. The tray 15a has multiple pockets (not shown) that are open upward. Each pocket stores one component BH. The pallet 15b is made of a dish-shaped member and is capable of holding the tray 15a on its upper surface.

[0015] 2, a drawer member 23R is provided on the upper surface side of the drawer table 23. The drawer member 23R is driven by a drawer member drive mechanism (not shown) to move in the Y direction on the drawer table 23. The drawer member 23R can engage with an engagement portion provided on the front side of the component storage unit 15, and by moving the drawer member 23R in the Y direction on the drawer table 23, the component storage unit 15 stored in the magazine 25 can be drawn onto the drawer table 23, or the component storage unit 15 on the drawer table 23 can be returned to the magazine 25.

[0016] In Fig. 2, the table lifting unit 24 is provided on the carriage 21 and is located in front of the magazine storage unit 22. The table lifting unit 24 includes a ball screw 24B extending in the Z direction and a lifting motor 24M that drives the ball screw 24B. The ball screw 24B is threadedly engaged with a nut 23N provided on the drawer table 23, and when the lifting motor 24M rotates the ball screw 24B, the drawer table 23 rises and falls (arrow A shown in Fig. 2). The table lifting unit 24 raises the drawer table 23, with the component storage unit 15 drawn out, to a predetermined height, thereby positioning the component storage unit 15 at a position (component supply height) where the component BH can be picked up by the mounting head 13 (Fig. 1).

[0017] Figure 3 shows the control system of the component mounting device 1. A control device 30 (see also Figure 2) provided in the component mounting device 1 controls the operation of the board transport conveyor 12, tray feeder 2, mounting head 13, and head movement mechanism 14. The board transport conveyor 12 is controlled by the control device 30 to load, position, and unload boards KB, and the tray feeder 2 positions a component storage unit 15 pulled out of a magazine 25 at the component supply height and supplies components BH to the mounting head 13. The head movement mechanism 14 moves the mounting head 13 between the tray feeder 2 and the board KB, and the mounting head 13 picks up the components BH supplied by the tray feeder 2 using nozzles 13N and mounts them on the board KB.

[0018] 2, 3, and 4 (FIG. 4 is an enlarged view of area RY shown in FIG. 1), tray feeder 2, which is the first equipment, is provided with a first connector 31 as a first connecting member that is a connecting member on the first equipment side. Also, main body 3 is provided with a second connector 32 as a connecting member on the second equipment side that is connectable to first connector 31. First connector 31 is attached to the end of cable 31C for electrical wiring that extends from the first equipment (tray feeder 2) side (FIG. 4).

[0019] 4, 5, and 6, an opening 3K that opens rearward is formed on a rear surface 3M, which is a surface along the XZ plane, of a cover member 3C (see also FIG. 1) that covers the base 11 of the main body 3. A space connected to the opening 3K is formed inside the cover member 3C, and two second connectors 32 are provided in that space.

[0020] 4, 5, and 6, the two second connectors 32 each have a connection port 32K facing the opening 3K (rearward) to mate with the first connector 31. The two first connectors 31 provided on the tray feeder 2 and the two second connectors 32 provided on the main body 3 are connected by manually mating the first connectors 31 with the second connectors 32 by an operator OP when the tray feeder 2 is positioned at a predetermined position where it can be coupled to the main body 3. At this time, the first connectors 31 are inserted into the space inside the cover member 3C through the opening 3K formed in the cover member 3C of the main body 3 and connected to the second connectors 32.

[0021] As described above, in the first embodiment, the first connector 31 is connected to the second connector 32 through the opening 3K formed in the second equipment (main body 3). When the first connector 31 and the second connector 32 are connected, the main body 3 and the tray feeder 2 are electrically connected, and electricity can be supplied from the main body 3 to the tray feeder 2 to operate the tray feeder 2.

[0022] When component mounting device 1 mounts components on board KB, first board transport conveyor 12 operates to bring in board KB from outside and position it at a predetermined work position. Once board KB is positioned at the work position, tray feeder 2 operates to draw component storage unit 15 from magazine 25 onto drawer table 23, and table lifting unit 24 raises drawer table 23 to the component supply height.

[0023] Once the component storage unit 15 is positioned at the component supply height, the head movement mechanism 14 is actuated to move the mounting head 13 horizontally, causing the mounting head 13 to reciprocate between the tray feeder 2 and the board KB positioned by the board transport conveyor 12. During this reciprocating movement, the mounting head 13 picks up the components BH supplied by the tray feeder 2 with the nozzle 13N and repeatedly performs a mounting turn to mount them on the board KB.

[0024] When all of the components BH to be mounted on the board KB have been mounted by the mounting head 13 repeatedly performing the mounting turn, the board transport conveyor 12 is activated to transport the board KB to the outside, thereby completing the component mounting operation for one board KB.

[0025] The component mounting device 1 having such a configuration is provided with a safety mechanism 40 for the connection of the electrical connectors (first connector 31 and second connector 32) between the first equipment (tray feeder 2) and the second equipment (main body 3). The safety mechanism 40 will be described below.

[0026] In Figures 4, 5 and 6, the safety mechanism 40 of the component mounting device 1 is configured to have a first engagement body 41 provided on the tray feeder 2 and a second engagement body 42 provided on the main body 3.

[0027] 4, 5 and 6, in the first embodiment, first engagement body 41 is made of a rod-shaped member extending in the X direction from the bottom of tray feeder 2. In the first embodiment, second engagement body 42 has a configuration including engagement member 43, shutter member 44 and guide member 45.

[0028] 5, 6, and 7(a) and (b), the engagement member 43 is made of a flat plate-like member extending along the YZ plane. The engagement member 43 has a notch-like engagement portion 43S that extends upward from its lower edge (and therefore opens downward). The shutter member 44 is made of a rectangular member that extends overall along the XZ plane. One vertical side of the shutter member 44 is connected to the engagement member 43. The guide member 45 is made of a flat plate-like member that extends along the YZ plane. The guide member 45 has two guide grooves 46 that extend in the vertical direction. The lower end of each guide groove 46 is bent horizontally, and the bent portion forms a lock portion 47 (FIGS. 7(b) and 8).

[0029] 5, 6, and 7(a) and (b), two guide pins 48 extending in the X direction are provided side by side, one above the other, on a surface (side surface 3W) along the YZ plane perpendicular to the rear surface 3M where the opening 3K of the cover member 3C is provided. These two guide pins 48 are respectively positioned in two guide grooves 46. A ring-shaped spacer 49 is inserted into each guide pin 48, and is positioned between the guide member 45 and the side surface 3W.

[0030] The second engagement body 42 can take one of two positions: a raised position (FIGS. 5 and 7(a)) in which the guide pins 48 are located in the locking portions 47 of the two guide grooves 46 provided in the guide member 45, and a lowered position (FIGS. 6 and 7(b)) in which the guide pins 48 abut against the upper ends of the two guide grooves 46. The second engagement body 42 can be manually switched between the raised and lowered positions by an operator OP.

[0031] When connecting the tray feeder 2 to the main body 3, the second engaging body 42 is positioned in the raised position, and the tray feeder 2 is moved closer to the main body 3. When the tray feeder 2 is positioned so that it can be connected to the main body 3, the first engaging body 41 is positioned almost directly below the second engaging body 42 (FIG. 5).

[0032] When the tray feeder 2 is positioned so that it can be coupled with the main body 3, the operator OP moves the second engagement body 42 from the raised position to the lowered position (FIG. 5 → FIG. 6 and FIG. 7(a) → FIG. 7(b)). As a result, the engagement portion 43S formed on the engagement member 43 of the second engagement body 42 receives the first engagement body 41, the first engagement body 41 is positioned within the engagement portion 43S, and the first engagement body 41 and the second engagement body 42 are engaged (FIG. 6 and FIG. 7(b)). When the first engagement body 41 and the second engagement body 42 are engaged, movement between the tray feeder 2 and the main body 3 is restricted, and the first equipment (tray feeder 2) and the second equipment (main body 3) cannot be separated.

[0033] As described above, positioning the second engagement body 42 in a lowered position when the tray feeder 2 is positioned so that it can be connected to the main body 3 means engaging the first engagement body 41 with the second engagement body 42, and in embodiment 1, the lowered position of the second engagement body 42 when the first engagement body 41 and the second engagement body 42 are engaged will be referred to as the ``engagement position'' below.

[0034] On the other hand, when the second engagement body 42, which is in the lowered position (engaged position), is moved to the raised position, the engagement member 43 of the second engagement body 42 moves upward away from the first engagement body 41, and the engagement between the first engagement body 41 and the second engagement body 42 is released. In the state in which the engagement between the first engagement body 41 and the second engagement body 42 is released, movement between the first equipment and the second equipment is not restricted, and the first equipment (tray feeder 2) and the second equipment (main body 3) can be pulled apart.

[0035] Positioning the second engagement body 42, which is positioned in the lowered position (engagement position) as described above, to the raised position means disengaging the first engagement body 41 and the second engagement body 42, and the raised position of the second engagement body 42 when the engagement between the first engagement body 41 and the second engagement body 42 is released will be referred to as the ``disengagement position'' in the following in embodiment 1.

[0036] As described above, the component mounting device 1 in embodiment 1 is configured to include a first engagement body 41 provided on the first equipment (tray feeder 2) and a second engagement body 42 provided on the second equipment (main body 3), which, when positioned at an engagement position where it engages with the first engagement body 41, prevents the first equipment and the second equipment from being separated, and when positioned at a disengagement position where it disengages from the first engagement body 41, allows the first equipment and the second equipment to be separated.

[0037] 5 and 7(a), when the second engaging body 42 is in the disengagement position, all or part of the opening 3K formed in the main body 3 is closed by the shutter member 44 of the second engaging body 42, preventing connection between the first connector 31 and the second connector 32. Therefore, when the second engaging body 42 is in the disengagement position and the first engaging body 41 and the second engaging body 42 are not engaged, the operator OP cannot connect the first connector 31 to the second connector 32.

[0038] On the other hand, when the second engaging body 42 moves from the disengaged position to the engaged position (FIG. 5 → FIG. 6 and FIG. 7(a) → FIG. 7(b)), the opening 3K formed in the main body 3 is opened, and the first connector 31 and the second connector 32 can be connected. Therefore, when the second engaging body 42 is located at the engaged position and the first engaging body 41 and the second engaging body 42 are engaged, the operator OP can connect the first connector 31 to the second connector 32, and can also pull out the first connector 31, which is connected to the second connector 32, from the second connector 32.

[0039] In this way, when the second engaging body 42 is in the disengaged position, it prevents the first connector 31 and the second connector 32 from being connected, and when the second engaging body 42 is in the engaged position, it allows the first connector 31 and the second connector 32 to be connected, so that when the first connector 31 and the second connector 32 are connected, the first engaging body 41 and the second engaging body 42 are always in an engaged state. Therefore, the first equipment and the second equipment will not be pulled apart while the first connector 31 and the second connector 32 remain connected, and a situation in which the connection portion of both equipment (the first connector 31, the second connector 32, and the cable 31C) is damaged by the action of pulling the equipment apart (the first equipment and the second equipment) is prevented.

[0040] 4 and 8, the first connector 31 connected to the second connector 32 is located on the path of movement of the second engagement body 42, which is located in the engagement position, when it is moved (upward) to the disengagement position, so the second engagement body 42, which is located in the engagement position, is prevented from moving to the disengagement position by the first connector 31 and second connector 32, which are connected. Therefore, in order to disengage the first engagement body 41 and the second engagement body 42, it is necessary to first disconnect the first connector 31 and the second connector 32, and the equipment will not be separated while the first connector 31 and the second connector 32 remain connected. This also prevents the connection between the two equipment from being damaged by the act of separating the equipment.

[0041] In embodiment 1, the second engagement body 42 was configured by combining an engagement member 43 manufactured as a part having the function of engaging with the first engagement body 41 and a shutter member 44 manufactured as a part having the function of preventing the connection between the first connector 31 and the second connector 32.However, the second engagement body 42 may also be manufactured as a single component having a part (engagement function part) having the function of engaging with the first engagement body 41 and a part (shutter function part) having the function of preventing the connection between the first connector 31 and the second connector 32. (Embodiment 2) Next, a second embodiment of the present invention will be described. Figures 9(a) and 9(b) show a safety mechanism 40A provided in a component mounting device 1 according to the second embodiment. The components of the component mounting device 1 according to the second embodiment, other than the safety mechanism 40A, are the same as those of the first embodiment, and components having the same functions as those of the first embodiment are given the same reference numerals as those of the first embodiment. Furthermore, in the configuration of the safety mechanism 40A, components having the same functions as those of the first embodiment are given the same reference numerals as those of the first embodiment.

[0042] 9(a) and 9(b), in the second embodiment, the first engaging body 41 provided on the first equipment is made of a member extending rearward and has a flange portion 41F extending in the vertical direction at its rear end. The second engaging body 42 provided on the second equipment is made of a member having an engaging portion 42F that can be positioned in front of the flange portion 41F of the first engaging body 41.

[0043] 9(a) and 9(b), the second engaging body 42 is provided with a guide groove 46A extending in the vertical direction. Two locking portions 47A that bend and extend horizontally are provided at the lower end and middle portion of the guide groove 46A. The second equipment is provided with a moving guide base 51 that extends in the vertical direction, and the moving guide base 51 is provided with two guide pins 52 that are inserted into the guide groove 46A.

[0044] In the safety mechanism 40A of the second embodiment, the second engagement body 42 can be in one of two positions: an engagement position (FIG. 9(a)) in which the upper guide pin 52 abuts against the upper end of the guide groove 46A, and a raised position (FIG. 9(b)) in which the two guide pins 52 are positioned within the two locking portions 47A of the guide groove 46A. The second engagement body 42 is manually switched between the lowered and raised positions by an operator OP. In the second embodiment, as shown in FIGS. 9(a) and 9(b), the two locking portions 47A extend further upward from their horizontally extending tips. When the second engagement body 42 is positioned in the raised position (FIG. 9(b)), the two guide pins 52 are positioned in the upwardly extending portions, thereby enhancing the stability of the posture of the second engagement body 42 in the raised position.

[0045] When the second engagement body 42 is moved from the lowered position to the raised position (FIG. 9(a) → FIG. 9(b)), the engagement portion 42F of the second engagement body 42 is positioned behind the flange portion 41F of the first engagement body 41, and the first engagement body 41 and the second engagement body 42 engage with each other (FIG. 9(b)). In the state in which the first engagement body 41 and the second engagement body 42 are engaged with each other, the movement of the first equipment and the second equipment is restricted, and the first equipment and the second equipment cannot be separated.

[0046] Thus, in the second embodiment, the upper part of the second engagement body 42 is a part (engagement function part) that has the function of engaging with the first engagement body 41. In the second embodiment, positioning the second engagement body 42 in the raised position while the first equipment is positioned in the coupled position relative to the second equipment means engaging the second engagement body 42 with the first engagement body 41, and the raised position of the second engagement body 42 when the first engagement body 41 and the second engagement body 42 are engaged will be referred to as the "engagement position" in the second embodiment hereinafter.

[0047] On the other hand, when the second engagement body 42, which is in the raised position (engaged position), is moved to the lowered position, the engagement portion 42F of the second engagement body 42 is no longer positioned behind the flange portion 41F of the first engagement body 41, and the engagement between the first engagement body 41 and the second engagement body 42 is released. In the state in which the engagement between the first engagement body 41 and the second engagement body 42 is released, movement between the first equipment and the second equipment is not restricted, and the first equipment and the second equipment can be pulled apart.

[0048] In this way, in embodiment 2, positioning the second engagement body 42, which is located in the raised position (engagement position), to the lowered position means disengaging the first engagement body 41 and the second engagement body 42, and the lowered position of the second engagement body 42 when the engagement between the first engagement body 41 and the second engagement body 42 is disengaged will be referred to as the "disengagement position" in the following in embodiment 2.

[0049] 9(a), when the second engaging body 42 is in the disengagement position, all or part of the connection port 32K of the second connector 32 is covered by the second engaging body 42, preventing connection between the first connector 31 and the second connector 32. Therefore, when the second engaging body 42 is in the disengagement position and the first engaging body 41 and the second engaging body 42 are not engaged, the worker OP cannot connect the first connector 31 and the second connector 32. In this way, in the second embodiment, the lower part of the second engaging body 42 serves as a portion (shutter function portion) that has the function of preventing connection between the first connector 31 and the second connector 32.

[0050] 9(b), when the second engaging body 42 is in the engaging position, the connection port 32K of the second connector 32 is not covered by the second engaging body 42, and the first connector 31 and the second connector 32 can be connected. Therefore, when the second engaging body 42 is in the engaging position and the first engaging body 41 and the second engaging body 42 are engaged, the worker OP can connect the first connector 31 to the second connector 32, and can also pull out the first connector 31, which is connected to the second connector 32, from the second connector 32.

[0051] As described above, also in the second embodiment, when the second engaging body 42 is in the disengaged position, it prevents the first connector 31 and the second connector 32 from being connected, and when the second engaging body 42 is in the engaged position, it allows the first connector 31 and the second connector 32 to be connected, so that when the first connector 31 and the second connector 32 are connected, the first engaging body 41 and the second engaging body 42 are always in an engaged state. Therefore, the first equipment and the second equipment will not be pulled apart while the first connector 31 and the second connector 32 remain connected, and a situation in which the connection between the two equipment is damaged by the action of pulling the equipment apart is prevented.

[0052] 9(b), the first connector 31 connected to the second connector 32 is located on the path of movement of the second engagement body 42, which is located in the engagement position, when it is moved (downward) to the disengagement position. Therefore, the second engagement body 42, which is located in the engagement position, is prevented from moving to the disengagement position by the first connector 31 and the second connector 32, which are connected. Therefore, in the second embodiment as well, in order to disengage the first engagement body 41 and the second engagement body 42, it is necessary to first disconnect the first connector 31 and the second connector 32, and the equipment will not be separated from each other while the first connector 31 and the second connector 32 remain connected. This also prevents the connection between the two equipment from being damaged by the operation of separating the equipment from each other. (Embodiment 3) Next, a third embodiment of the present invention will be described. Figures 10(a) and 10(b) show a safety mechanism 40B of a component mounting device 1 according to the third embodiment. The components of the component mounting device 1 according to the third embodiment, other than the safety mechanism 40B, are the same as those of the first embodiment, and components having the same functions as those of the first embodiment are given the same reference numerals as those of the first embodiment. Furthermore, in the configuration of the safety mechanism 40B, components having the same functions as those of the first embodiment are given the same reference numerals as those of the first embodiment.

[0053] 10(a) and 10(b), in the third embodiment, the first engagement body 41 provided on the first equipment has an engagement opening 41G that opens downward. The second engagement body 42 provided on the second equipment is made of a rectangular flat plate member and is configured to be movable in the vertical direction. In the third embodiment, the upper end of the second engagement body 42 is a portion (engagement function portion) that has the function of engaging with the first engagement body 41, and the lower end is a portion (shutter function portion) that has the function of preventing the first connector 31 and the second connector 32 from being connected.

[0054] 10(a) and (b), the second engagement body 42 can take one of two positions: an engagement position (FIG. 10(a)) in which the upper end (engagement function portion) is inserted into the engagement opening 41G of the first engagement body 41 and engages with the first engagement body 41, and a disengagement position (FIG. 10(b)) in which the upper end (engagement function portion) is removed from the engagement opening 41G and disengaged from the first engagement body 41. The second engagement body 42 is manually switched between the engagement position and the disengagement position by an operator OP.

[0055] When the second engagement body 42 is in the engaged position (FIG. 10(a)), movement between the first and second equipment is restricted, and the first and second equipment cannot be separated. On the other hand, when the second engagement body 42 is in the disengaged position (FIG. 10(b)), the engagement between the first engagement body 41 and the second engagement body 42 is released. When the engagement between the first engagement body 41 and the second engagement body 42 is released, movement between the first and second equipment is not restricted, and the first and second equipment can be separated.

[0056] 10(b), when the second engaging body 42 is in the disengagement position, all or part of the connection port 32K of the second connector 32 is covered by the second engaging body 42, preventing connection between the first connector 31 and the second connector 32. Therefore, when the second engaging body 42 is in the disengagement position and the first engaging body 41 and the second engaging body 42 are not engaged, the worker OP cannot connect the first connector 31 and the second connector 32.

[0057] 10(a), when the second engaging body 42 is in the engaging position, the connection port 32K of the second connector 32 is not covered by the second engaging body 42, and the first connector 31 and the second connector 32 can be connected. Therefore, when the second engaging body 42 is in the engaging position and the first engaging body 41 and the second engaging body 42 are engaged, the worker OP can connect the first connector 31 to the second connector 32, and can also pull out the first connector 31, which is connected to the second connector 32, from the second connector 32.

[0058] As described above, also in the third embodiment, when the second engaging body 42 is in the disengaged position, it prevents the first connector 31 and the second connector 32 from being connected, and when the second engaging body 42 is in the engaged position, it allows the first connector 31 and the second connector 32 to be connected, so that when the first connector 31 and the second connector 32 are connected, the first engaging body 41 and the second engaging body 42 are always in an engaged state. Therefore, the first equipment and the second equipment will not be pulled apart while the first connector 31 and the second connector 32 remain connected, and the connection between the two equipment will not be damaged by the action of pulling the equipment apart.

[0059] 10(b), when the first connector 31 is connected to the second connector 32, the connected first connector 31 is located on the path of movement of the second engagement body 42, which is located in the engagement position, when it is moved (downward) to the disengagement position. Therefore, the second engagement body 42, which is located in the engagement position, is prevented from moving to the disengagement position by the connected first connector 31 and second connector 32. Therefore, in the third embodiment as well, in order to disengage the first engagement body 41 and the second engagement body 42, it is necessary to first disconnect the first connector 31 and the second connector 32, and the equipment will not be separated from each other while the first connector 31 and the second connector 32 remain connected. This also prevents the connection between the two equipment from being damaged by the operation of separating the equipment from each other. (Fourth embodiment) 11(a) and 11(b) show a safety mechanism 40B of the component mounting apparatus 1 according to the fourth embodiment. The configuration of the safety mechanism 40B according to the fourth embodiment is the same as that of the safety mechanism 40B according to the third embodiment, except that the second engagement body 42 moves horizontally (left and right) between the engagement position and the disengagement position, rather than vertically as in the third embodiment. FIG. 11(a) shows a state in which the second engagement body 42 is in the engagement position and engaged with the first engagement body 41, and corresponds to FIG. 10(a) in the third embodiment. FIG. 11(b) shows a state in which the second engagement body 42 is in the disengagement position and disengaged from the first engagement body 41, and corresponds to FIG. 10(b) in the third embodiment. The effects of the fourth embodiment are the same as those of the third embodiment. (Embodiment 5) Next, a fifth embodiment of the present invention will be described. Figures 12(a) and 12(b) show a safety mechanism 40C of a component mounting device 1 according to the fifth embodiment. The components of the component mounting device 1 according to the fifth embodiment, other than the safety mechanism 40C, are the same as those of the first embodiment, and components having the same functions as those of the first embodiment are given the same reference numerals as those of the first embodiment. Furthermore, in the configuration of the safety mechanism 40C, components having the same functions as those of the first embodiment are given the same reference numerals as those of the first embodiment.

[0060] 12(a) and 12(b), the fifth embodiment is the same as the third and fourth embodiments in that the first engagement body 41 provided in the first equipment has an engagement opening 41G that opens downward. The second engagement body 42 is made of a flat member having a fan shape and is configured to be rotatable about a swing shaft 42J that extends horizontally. In the fifth embodiment, the portion of the second engagement body 42 located above the swing shaft 42J is a portion (an engagement function portion) that has the function of engaging with the first engagement body 41, and the portion located below the swing shaft 42J is a portion (a shutter function portion) that has the function of preventing the first connector 31 and the second connector 32 from being connected.

[0061] 12(a) and (b), the second engagement body 42 can move (swing) between an engagement position (FIG. 12(a)) where a portion (engagement function portion) located above the swing shaft 42J is inserted into the engagement opening 41G of the first engagement body 41 to engage with the first engagement body 41, and a disengagement position (FIG. 12(b)) where the portion (engagement function portion) located above the swing shaft 42J is removed from the engagement opening 41G to disengage from the first engagement body 41, and can take either of these two positions. The second engagement body 42 can be manually switched between the engagement position and the disengagement position by an operator OP.

[0062] When the second engagement body 42 is in the engaged position (FIG. 12(a)), movement between the first and second equipment is restricted, and the first and second equipment cannot be separated. On the other hand, when the second engagement body 42 is in the disengaged position (FIG. 12(b)), the engagement between the first engagement body 41 and the second engagement body 42 is released. When the engagement between the first engagement body 41 and the second engagement body 42 is released, movement between the first and second equipment is not restricted, and the first and second equipment can be separated.

[0063] 12(b), when the second engaging body 42 is in the disengagement position, the connection port 32K of the second connector 32 is covered by the second engaging body 42, preventing connection between the first connector 31 and the second connector 32. Therefore, when the second engaging body 42 is in the disengagement position and the first engaging body 41 and the second engaging body 42 are not engaged, the worker OP cannot connect the first connector 31 and the second connector 32.

[0064] 12(a), when the second engaging body 42 is in the engaging position, the connection port 32K of the second connector 32 is not covered by the second engaging body 42, and the first connector 31 and the second connector 32 can be connected. Therefore, when the second engaging body 42 is in the engaging position and the first engaging body 41 and the second engaging body 42 are engaged, the operator OP can connect the first connector 31 to the second connector 32, and can also pull out the first connector 31, which is connected to the second connector 32, from the second connector 32.

[0065] As described above, also in the fifth embodiment, when the second engaging body 42 is in the disengaged position, it prevents the first connector 31 and the second connector 32 from being connected, and when the second engaging body 42 is in the engaged position, it allows the first connector 31 and the second connector 32 to be connected, so that when the first connector 31 and the second connector 32 are connected, the first engaging body 41 and the second engaging body 42 are always in an engaged state. Therefore, the first equipment and the second equipment will not be pulled apart while the first connector 31 and the second connector 32 remain connected, and a situation in which the connection between the two equipment is damaged by the action of pulling the equipment apart is prevented.

[0066] 12(b), when the first connector 31 is connected to the second connector 32, the connected first connector 31 is located on the path of movement of the second engagement body 42, which is located in the engagement position, when it is moved to the disengagement position. Therefore, the second engagement body 42, which is located in the engagement position, is prevented from moving to the disengagement position by the connected first connector 31 and second connector 32. Therefore, in the fifth embodiment as well, in order to disengage the first engagement body 41 and the second engagement body 42, it is necessary to first disconnect the first connector 31 and the second connector 32, and the equipment will not be separated from each other while the first connector 31 and the second connector 32 remain connected. This also prevents the connection between the two equipment from being damaged by the operation of separating the equipment from each other. (Sixth embodiment) Next, a sixth embodiment of the present invention will be described. Figures 13(a) and 13(b) show a safety mechanism 40D of a component mounting device 1 according to the sixth embodiment. The components of the component mounting device 1 according to the sixth embodiment, other than the safety mechanism 40D, are the same as those of the first embodiment, and components having the same functions as those of the first embodiment are given the same reference numerals as those of the first embodiment. Furthermore, in the configuration of the safety mechanism 40D, components having the same functions as those of the first embodiment are given the same reference numerals as those of the first embodiment.

[0067] In the sixth embodiment, as shown in Figures 13(a) and 13(b), the first engagement body 41 provided on the first equipment has an engagement opening 41G that opens downward. This is the same as in the third, fourth, and fifth embodiments. The second engagement body 42 provided on the second equipment is composed of an engagement member 43 and a shutter member 44. The engagement member 43 and the shutter member 44 are each made of a flat plate-shaped member, and the engagement member 43 and the shutter member 44 are each able to slide up and down while their lateral movement is restricted by a guide member (not shown).

[0068] The second equipment is provided with a bifurcated arm 61 having two arms 61W that can rotate freely around a swing shaft 42J extending horizontally. Sliders 62 are provided at the ends of each of the two arms 61W of the bifurcated arm 61, and these sliders 62 are located within slide guides 63 that are provided on the engaging member 43 and the shutter member 44 and extend horizontally. Therefore, when the bifurcated arm 61 swings around the swing shaft 42J, the engaging member 43 and the shutter member 44 move vertically in synchronization with this.

[0069] In the sixth embodiment, by swinging the bifurcated arm 61, the second engagement body 42 can be placed in one of two positions: an engagement position (FIG. 13(a)) in which the engagement member 43 is inserted through the engagement opening 41G of the first engagement body 41 and engaged with the first engagement body 41, and a disengagement position (FIG. 13(b)) in which the engagement member 43 positioned in the engagement position is removed from the engagement opening 41G and disengaged from the first engagement body 41. The second engagement body 42 is manually switched between the engagement position and the disengagement position by an operator OP.

[0070] When the second engagement body 42 is in the engaged position (FIG. 13(a)), movement between the first and second equipment is restricted, and the first and second equipment cannot be separated. On the other hand, when the second engagement body 42 is in the disengaged position (FIG. 13(b)), the engagement between the first engagement body 41 and the second engagement body 42 is released. When the engagement between the first engagement body 41 and the second engagement body 42 is released, movement between the first and second equipment is not restricted, and the first and second equipment can be separated.

[0071] 13(b), when the second engaging body 42 is in the disengagement position, all or part of the connection port 32K of the second connector 32 is covered by the shutter member 44 of the second engaging body 42, preventing connection between the first connector 31 and the second connector 32. Therefore, when the second engaging body 42 is in the disengagement position and the first engaging body 41 and the second engaging body 42 are not engaged, the operator OP cannot connect the first connector 31 and the second connector 32.

[0072] 13(a), when the second engaging body 42 is in the engaging position, the connection port 32K of the second connector 32 is not covered by the shutter member 44, and the first connector 31 and the second connector 32 can be connected. Therefore, when the second engaging body 42 is in the engaging position and the first engaging body 41 and the second engaging body 42 are engaged, the worker OP can connect the first connector 31 to the second connector 32, and can also pull out the first connector 31, which is connected to the second connector 32, from the second connector 32.

[0073] As described above, also in the sixth embodiment, when the second engaging body 42 is in the disengaged position, it prevents the first connector 31 and the second connector 32 from being connected, and when the second engaging body 42 is in the engaged position, it allows the first connector 31 and the second connector 32 to be connected, so that when the first connector 31 and the second connector 32 are connected, the first engaging body 41 and the second engaging body 42 are always in an engaged state. Therefore, the first equipment and the second equipment will not be pulled apart while the first connector 31 and the second connector 32 remain connected, and a situation in which the connection between the two equipment is damaged by the action of pulling the equipment apart is prevented.

[0074] 13(b), when the first connector 31 is connected to the second connector 32, the connected first connector 31 is located on the path of movement of the second engagement body 42, which is located in the engagement position, when it is moved to the disengagement position. Therefore, the second engagement body 42, which is located in the engagement position, is prevented from moving to the disengagement position by the connected first connector 31 and second connector 32. Therefore, in the sixth embodiment as well, in order to disengage the first engagement body 41 and the second engagement body 42, it is necessary to first disconnect the first connector 31 and the second connector 32, and the equipment will not be separated from each other while the first connector 31 and the second connector 32 remain connected. This also prevents the connection between the two equipment from being damaged by the operation of separating the equipment from each other.

[0075] As described above, in the component mounting device 1 according to the first to sixth embodiments, when the second engaging body 42 is in the disengagement position, it prevents the first connector 31 from connecting with the second connector 32, and when the second engaging body 42 is in the engagement position, it allows the first connector 31 to connect with the second connector 32. Therefore, when the first connector 31 and the second connector 32 are connected, the first engaging body 41 and the second engaging body 42 are always in an engaged state. Therefore, the first equipment and the second equipment are not pulled apart while the first connector 31 and the second connector 32 remain connected, and the connection portion of the two equipment (the first connector 31, the second connector 32, and the cable 31C) is prevented from being damaged by the action of pulling the equipment apart.

[0076] Furthermore, in the component mounting device 1 according to the first to sixth embodiments, the first connector 31 connected to the second connector 32 is located on the path of movement of the second engaging body 42, which is located at the engaging position, when it is moved to the disengaging position. Therefore, the second engaging body 42, which is located at the engaging position, is prevented from moving to the disengaging position by the connected first connector 31 and second connector 32. Therefore, in order to disengage the first engaging body 41 and the second engaging body 42, it is necessary to first disconnect the first connector 31 and the second connector 32. Therefore, the first connector 31 and the second connector 32 are not disconnected from each other while they are connected. This also prevents the connection between the two pieces of equipment from being damaged by the operation of disconnecting the two pieces of equipment.

[0077] While the embodiments of the present invention have been described above, the present invention is not limited to the above and various modifications are possible. For example, in the above-described embodiments, two first connecting members (first connectors 31) and two second connecting members (second connectors 32) are provided, but there may be one first connecting member and one second connecting member, or three or more first connecting members. Furthermore, in the above-described embodiments, the first connecting member and the second connecting member are connectors for electrical wiring, but they may also be connectors for air supply piping, etc.

[0078] Furthermore, in the above-described embodiment, the first equipment on which the first engaging body 41 is provided is the tray feeder 2, which is a component supply unit of the component mounting device 1, and the second equipment on which the second engaging body 42 is provided is the main body 3 of the component mounting device 1. However, the first equipment on which the first connecting member and the first engaging body are provided may be the main body 3, and the second equipment on which the second connecting member and the second engaging body are provided may be the tray feeder 2. Furthermore, it is sufficient that one of the first equipment and the second equipment is a component supply unit, and the other may be a device other than the main body 3 (for example, a magazine stocker that replenishes magazines to the tray feeder).
