  Next, a control system for a gaming machine production line according to the present invention will be described below with reference to the accompanying drawings by way of preferred embodiments. In the embodiment, in a production line for manufacturing a pachinko machine, an operator uses various members in a predetermined work area with respect to a pachinko machine (hereinafter referred to as a work target product) to which various members such as decorative members and electronic parts are attached. An inspection line control system for inspecting the mounting state, operating state, and the like will be described as an example.

  FIG. 1 is an explanatory diagram schematically showing an inspection line KL of the gaming machine manufacturing line according to the embodiment. The inspection line KL is composed of two lines, a first transfer line 10 and a second transfer line 11 for transferring the work target product X in a predetermined direction, and the work target product X to which various members are attached in the previous process is supplied to the supply line. The first and second transport lines 10 and 11 are supplied via the 30. Here, the first transport line 10 and the second transport line 11 have basically the same configuration, and are separated in the transport direction of the work target product X in the main line ML and the main line ML extending linearly. And a plurality of sublines SL that branch in a direction orthogonal to the main line ML, and each subline SL is configured to have one work area SA that can perform a predetermined inspection work. In the following description, the main line ML of the first transport line 10 is referred to as a first main line ML1 and the main line ML of the second transport line 11 is referred to as a second main line ML2 as necessary. The sub lines SL branched from the first main line ML1 are referred to as first to third sub lines SL1 to SL3 in order from the upstream side, and the sub lines SL branched from the second main line ML2 are fourth from the upstream side. To sixth sublines SL4 to SL6.

  The first main line ML1 and the second main line ML2 are installed so as to extend substantially in parallel, and the first to third sublines SL1 to SL3 and the fourth to sixth sublines SL4 to SL6 are respectively It is provided so as to branch in the opposite direction from the corresponding main lines ML1, ML2, and is configured so that the first to third sublines SL1 to SL3 and the fourth to sixth sublines SL4 to SL6 do not interfere with each other. . That is, in FIG. 1, the first to third sublines SL1 to SL3 extend upward from the first main line ML1, and the fourth to sixth sublines SL4 to SL6 downward from the second main line ML2. It is extended.

  A pachinko machine (hereinafter referred to as a work-completed product Y (FIG. 6) in which inspection work in the work area SA has been completed is located below the first and second transfer lines 10 and 11 (main lines ML and sub-lines SL). (Refer to FIG. 9)) and a carry-out line 40 (see FIG. 2) for carrying out) are provided, and the inspection line KL and the carry-out line 40 have a two-stage structure. Thus, the inspection line KL and the carry-out line 40 have a two-stage structure that prevents the entire manufacturing line from being enlarged in the width direction. Note that the first and second transfer lines 10 and 11 positioned in the upper stage are set so as to be substantially at the waist height position of the worker, and the worker can easily work in a standing posture in the work area SA. It is like that.

(Main line)
Each main line ML includes a plurality of first rotary transfer devices (transfer means) 13 and first transfer devices (transfer means) 16 that can transfer and stop transfer of an arbitrary work target product X. It is configured, and by operating each of the conveying devices 13 and 16 based on the control of the control means 50 (see FIG. 2), the work target product X can be conveyed in a predetermined conveying direction (left direction in FIG. 1). It has become. Here, each of the first rotary transfer device 13 and the first transfer device 16 is an independent small roller conveyor type, and is individually activated and deactivated by the control means 50 and necessary. Accordingly, the work product X can be transported by operating the transport devices 13 and 16 according to the above. And each said conveying apparatus 13 and 16 is set to the magnitude | size which can hold | maintain one work object X in the stop state at the time of the operation stop. Each of the first rotary transfer device 13 and the first transfer device 16 includes support means (not shown) that supports the upper side of the work target item X. It is configured to prevent the work target product X being conveyed from falling.

  Three first rotary transfer devices 13 are provided in each main line ML, and each of the sub-lines SL is branched corresponding to each first rotary transfer device 13. Here, each of the first rotary transfer devices 13 is controlled by the control means 50 to a first position where the work target product X can be transferred toward the downstream side of the corresponding main line ML (FIG. 3 ( a)), and a second position (FIG. 3) at which the work target product X can be transported toward each of the sub-lines SL corresponding to the first rotary transport devices 13 by rotating approximately 90 ° from the first position. (see (b)), and the conveyance direction of the work target product X can be appropriately changed by rotating the first rotary conveyance device 13. The first rotary transport device 13 is always positioned at the first position, can transport (replenish) the work target product X toward the downstream side of each main line ML, and from the upstream side. It is held so as to be able to accept the work object X to be conveyed. Further, by rotating the work target product X by 90 ° by the first rotary transfer device 13, the work area SA arrives in a posture in which the front side of the work target product X is directed to the worker side. You can work easily.

  Each main line ML is configured such that two first transfer devices 16, 16 are positioned upstream of the first rotary transfer device 13, and one first rotary transfer device 13. In addition, a standby area TA (see FIG. 1) in which a maximum of three work target items X can be waited is set by the two first transfer devices 16 and 16 located upstream thereof. In the following description, the standby areas TA corresponding to the first to sixth sublines SL1 to SL6 are referred to as first to sixth standby areas TA1 to TA6 as necessary.

  Thus, by providing the first to sixth standby areas TA1 to TA6 corresponding to the first to sixth sublines SL1 to SL6, the first to sixth standbys corresponding to the sublines SL1 to SL6 are provided. The work target product X waiting in the areas TA1 to TA6 is sent out, and the work target product X is replenished from the upstream standby area TA to the downstream standby area TA in each main line ML as necessary. Yes. In the following description, as shown in FIG. 3, the first rotary transport device 13 in each standby area TA is placed upstream of the first standby position and the first rotary transport device 13. The first transport device 16 that is positioned is referred to as a second standby position, and the first transport device 16 that is positioned one upstream from the second standby position is referred to as a third standby position. Here, in the embodiment, in the standby area TA, the control means 50 causes each of the transfer devices 13, the control means 50 to preferentially wait for the work target product X in the order of the first standby position, the second standby position, and the third standby position. 16 is controlled.

  Further, as shown in FIG. 2, each of the transfer devices 13, 16, 16 corresponding to the first to third standby positions has a first detection sensor 14 for detecting the work target product X, a second detection, and the like. A sensor 17 and a third detection sensor 18 are provided correspondingly. Here, the detection results of the detection sensors 14, 17, and 18 are output to the storage means 52 of the control means 50, and the storage means 52 is connected to each standby area based on the detection results of the detection sensors 14, 17, and 18. The waiting number of the work target product X in the TA (hereinafter simply referred to as the waiting number of the waiting area TA) can be individually stored. Based on the standby number of the work target product X stored in the storage unit 52, the control unit 50 individually activates and deactivates the first rotary conveyance device 13 and the first conveyance device 16. It is like that.

  That is, when the work target product X is sent from any of the first rotary transfer devices 13 (that is, the first standby position) toward the downstream standby area TA or the corresponding subline SL, the first rotation is performed. The work target product X at the second standby position in the standby area TA to which the type transport device 13 belongs is transported to the first standby position, and the work target product X at the third standby position is transported to the second standby position. Thus, by providing the standby areas TA for waiting for the work target product X at the branch positions between the main line ML and the subline SL, the work on the work target product X is completed in the work area SA of any subline SL. In this case, the next work target product X can be quickly sent to the subline SL.

  Here, the storage means 52, when the work target product X is sent from the first rotary transfer device 13 to the downstream standby area TA or the corresponding subline SL, the standby for sending the work target product X. It is set so that the waiting number of the work target product X corresponding to the area TA is decremented by one. Specifically, when the first detection sensor 14 of the first rotary transport device 13 in the first standby area TA1 does not detect the work target product X, the standby number in the first standby area TA1 is decremented by 1, and similarly When the first detection sensor 14 of the first rotary transfer device 13 in the second to sixth standby areas TA2 to TA6 no longer detects the work target product X, the corresponding second to sixth standby areas TA2 to TA6 The waiting number is decremented by one.

  Further, when the work target product X is replenished (conveyed) from the upstream side to the downstream standby area TA, the transport devices 13 and 16 to which the work target product X transported from the upstream standby area TA is to be replenished. The first to third detection sensors 14, 17, 18 detect the work target product X so that the number of standby in the downstream standby area TA to which the work target product X is replenished is incremented by one. Is done. Specifically, in a state where the work target item X is not waiting in the standby area TA (that is, a state where the standby number is “0”), the first rotary transport device 13 corresponding to the first standby position has the first. When the detection sensor 14 detects the work target product X, the waiting number is incremented by 1, and in the state where one work target product X is waiting in the standby area TA (that is, the state where the standby number is “1”), When the second detection sensor 17 of the first transfer device 16 corresponding to the 2 standby position detects the work target product X, the standby number is incremented by 1, and two work target products X are kept waiting in the standby area TA. In the state (that is, the state where the standby number is “2”), the standby number is incremented by 1 when the third detection sensor 18 of the first transport device 16 corresponding to the third standby position detects the work target product X. .

  In addition, regarding the replenishment (conveyance) of the work target item X from the standby area TA located on the upstream side to the standby area TA located on the downstream side, the control means 50 is adjacent to the storage means 52 stored therein. When the number of standbys of the work target product X in the matching standby area TA is compared, and the standby number of the standby area TA located on the upstream side is smaller, the work target product X to the standby area TA located on the downstream side Is replenished (conveyed), and after the standby number of work target products X in the standby area TA located on the upstream side becomes equal to or more than the same number, the work target products X are replenished (transferred) to the downstream standby area TA. Thus, each of the first rotary transfer device 13 and the first transfer device 16 is controlled to be operated.

  However, when comparing the number of standbys in the upstream standby area TA and the downstream standby area TA, the control means 50 moves the work target item X in the upstream and downstream standby areas TA to be compared. Is set to compare the number of standbys after each stop. That is, after the addition / subtraction of the waiting number is completed and the waiting number of each waiting area TA is determined, the waiting number of the waiting area TA adjacent to the upstream side and the downstream side is compared, and the work object is moved from the upstream side to the downstream side. By conveying the product X, the work target product X is excessively supplied to the downstream standby area TA, and the shortage of the work target product X in the upstream standby area TA can be prevented.

  Here, a specific example shown in FIGS. 4 to 9 will be described. As shown in FIG. 4, two work target items X stand by in the first standby area TA1 (standby number “2”), and two work target items X stand by in the second standby area TA2 (standby number “2”). In addition, in the state where the three work target items X are waiting in the third waiting area TA3 (the number of waiting is “3”), the number of waiting in the second waiting area TA2 is smaller than the number of waiting in the third waiting area TA3. Therefore, the replenishment of the work target item X from the second standby area TA2 to the third standby area TA3 is temporarily stopped. On the other hand, since the number of standbys in the first standby area TA1 is “2” and the number of standbys in the second standby area TA2 is “2”, the third standby position in the second standby area TA2 from the first standby area TA1. The work target product X is replenished (conveyed) (see FIG. 5). At this time, since the first detection sensor 14 of the first rotary transfer device 13 in the first standby area TA1 does not detect the work target product X, the number of standby in the first standby area TA1 is decremented by one. Becomes “1”. However, at this time, the waiting number in the second waiting area TA2 is not added and the waiting number remains “2”. Note that the work target item X at the second standby position in the first standby area TA1 is transported to the first standby position. However, in this case, the number of standby in the first standby area TA1 does not increase or decrease because the work target item X moves within the same standby area TA (first standby area TA1).

  Furthermore, when the work in the work area SA of the second subline SL2 is completed, the work target product X is transported from the second standby area TA2 toward the second subline SL2. At this time, since the first detection sensor 14 of the first rotary transfer device 13 in the second standby area TA2 does not detect the work target product X, the standby number in the second standby area TA2 is decremented by 1, and the standby number. Becomes “1” (see FIG. 6). Thereafter, as shown in FIG. 7, the work target item X at the second standby position in the second standby area TA2 is conveyed to the first standby position. Here, the number of standby in the second standby area TA2 is “1”, but the work target item X transported from the first standby area TA1 arrives at the third standby position and the third detection sensor. When 18 detects the work target product X, the waiting number in the second waiting area TA2 is incremented by 1, and becomes “2”. In addition, since the work target product X has moved from the second standby position in the second standby area TA2, the work target product X that has arrived at the third standby position from the first standby area TA1 moves to the second standby position. However, in this case, because the work target item X moves within the same waiting area TA (second waiting area TA2), the number of waiting in the second waiting area TA2 does not increase or decrease.

  Furthermore, when the work in the work area SA of the third subline SL3 is completed, the work target product X is transported from the third standby area TA3 toward the third subline SL3. At this time, since the first detection sensor 14 of the first rotary transfer device 13 in the third standby area TA3 does not detect the work target product X, the number of standby in the third standby area TA3 is decremented by one. Becomes “2”. After that, as shown in FIG. 8, the work target item X in the second standby position in the third standby area TA3 is conveyed to the first standby position, and the work target item X in the third standby position is moved to the second standby position. Be transported. However, in this case, the number of standby in the third standby area TA3 does not increase or decrease because the work target item X moves within the same standby area TA (third standby area TA3).

  At this time, the number of waiting in each of the second and third waiting areas TA2, TA3 is “2”, but the work target product X is moving in the second and third waiting areas TA2, TA3. The number of waiting in the waiting area TA is not compared. Therefore, as shown in FIG. 8, when the work target product X that has arrived at the first and second standby positions in the second standby area TA2 waits as it is and the work in the work area SA of the second subline SL2 is completed. The work target product X at the first standby position is transported toward the second subline SL2. In addition, when the work target product X arrives at each of the first and second standby positions in the third standby area TA3 before the work target product X is transported toward the second subline SL2 (see FIG. 9), Since the standby numbers of the two standby areas TA2 and TA3 are compared, and the standby numbers of both standby areas TA2 and TA3 are the same (both standby numbers are “2”), the second standby area TA2 to the third standby area TA3 The work target product X is replenished (conveyed) to the second standby position in the standby area TA3. At this time, as described above, when the first detection sensor 14 of the first rotary transport device 13 in the second standby area TA2 no longer detects the work target product X, the standby in the second standby area TA2 is performed. The number is decremented by 1 and the waiting number becomes “1”. At this time, the waiting number in the third waiting area TA3 is not added and the waiting number remains “2”. In this way, by increasing / decreasing the standby number of each standby area TA based on the above-described conditions, and comparing the standby number of the standby area TA after the movement of the work target product X in each standby area TA is stopped, The work target product X can be made to wait substantially evenly in each standby area TA. Note that the work target item X is sequentially supplied from the supply line 30 to the first standby area TA1.

(About sublines)
As shown in FIG. 1, each of the sub-lines SL is connected to the second transfer device 20 connected to the first rotary transfer device 13 and the second transfer device 20, and the work area SA is A third conveying device 23 provided and a lift means 27 connected to the third conveying device 23 and moving work completion products Y from the work area SA to the carry-out line 40 are arranged in a row. Has been. In other words, in the embodiment, an operator is positioned in the vicinity of the third transfer device 23, and a predetermined inspection work is performed on the work target product X stopped at the third transfer device 23. .

  The second and third conveying devices 20 and 23 are small roller conveyor types that are independent from each other, and are individually activated and deactivated by the control means 50, similar to the first conveying device 16. Are controlled, and the work target product X or the work completed product Y is transported from the first rotary transport device 13 toward the lift means 27 by the operation of the transport devices 20 and 23. Each of the second and third transfer devices 20 and 23 is set to a size that can hold one work target product X or work completed product Y in a stopped state when the operation is stopped. That is, the work target product X sent from the first rotary transfer device 13 to the corresponding sublines SL1 to SL6 is caused to temporarily stand by the second transfer device 20, and the work in the work area SA is completed. Later, the work completion product Y is transported to the lift means 27 and the work target product X is transported from the second transport device 20 to the third transport device 23 (work area SA) to be the next work target product X. In contrast, inspection work is performed. Each of the second and third transfer devices 20 and 23 is provided with a support means (not shown) for supporting the upper side of the work target product X, and work carried by each of the transfer devices 20 and 23. It is configured to prevent the target product X from falling.

  Each of the second transport device 20 and the third transport device 23 is provided with a fourth detection sensor 21 and a fifth detection sensor 24 for detecting the work target product X or the work completion product Y, When the fifth detection sensor 24 provided in the third transport device 23 no longer detects the work completion product Y, the work target product X of the second transport device 20 is transported to the third transport device 23 (work area SA). Thus, the control means 50 controls the operation of the second transport device 20. Similarly, when the fourth detection sensor 21 provided in the second transport device 20 no longer detects the work target product X, the corresponding first rotary transport device 13 is rotated to the second position, and the second The work target product X is transported from one rotary transport device 13 to the second transport device 20.

  In addition, a switch 25 (see FIG. 2) connected to the identification means 54 provided in the control means 50 is provided in the vicinity of each work area SA. The identification means 54 identifies whether or not the SA (subline SL) is operating. That is, when starting the inspection work, when the operator turns on the switch 25 corresponding to the work area SA, the identification means 54 recognizes that the corresponding work area SA (subline SL) is in operation, When the switch 25 is turned off, the identification means 54 recognizes that the corresponding work area SA (subline SL) is not operating. In the embodiment, the switch 25 of the work area SA provided in the sixth subline SL6 in the second transport line 11 is OFF, and the first transport line 10 is provided in the first to third sublines SL1 to SL3. Three work areas SA are operating, and two work areas SA provided on the fourth and fifth sublines SL4 and SL5 are operating in the second transport line 11.

  Here, based on the identification information of the identification means 54, the control means 50 waits for the work item X in the standby area TA corresponding to the working area SA (subline SL) that is in operation and is in operation. The operation of each of the first rotary transfer device 13 and the first transfer device 16 is controlled so that the work target product X does not wait in the waiting area TA corresponding to the non-working area SA (subline SL). Specifically, the work target product X is placed in each of the first to fifth standby areas TA1 to TA5 excluding the sixth standby area TA6 corresponding to the sixth subline SL6 provided with the work area SA that is not operating in the embodiment. The control means 50 controls the operation of each of the transfer devices 13 and 16 so as to wait (see FIG. 1). Thus, the work area SA to be operated can be determined according to the production plan by causing the work target product X to stand by in the first to fifth standby areas TA1 to TA5 corresponding to the work area SA that is operating. It has become.

  Further, the lift means 27 moves to a receiving position where the work completion product Y from the work area SA (third transfer device 23) can be received, and moves downward from the receiving position, and then completes the work completion product to the carry-out line 40. It is configured to be movable up and down to a delivery position where Y can be delivered, and is always positioned to the delivery position so as to accept the work completion product Y. Then, when the sixth detection sensor 28 provided in the lift means 27 detects the work completion product Y, the control means 50 controls the operation so that the lift means 27 is moved to the delivery position. The lift means 27 incorporates a small roller conveyor type transport device so that the work completion product Y can be transported from the lift means 27 to the carry-out line 40 after moving to the delivery position. . In this way, by configuring the lift means 27 to transport the work completion product Y to the carry-out line 40, it is possible to save the operator from having to move the work completion product Y to the carry-out line 40 after the work is completed, thereby improving work efficiency. Is planned.

(About supply line)
The supply line 30 for supplying the work target product X toward the first and second transfer lines 10 and 11 includes a supply conveyor 32 connected to the first transfer line 10 (first main line ML1), and the supply The conveyor 32 is branched from the downstream end of the conveyor 32 so as to extend to the second conveyance line 11 side, and is connected to the second conveyance line 11 (second main line ML2). The work target product X is supplied from the supply conveyor 32, and the work target product X from the supply conveyor 32 is supplied to the second transport line 11 via the connection conveyor 34. A branch position between the supply conveyor 32 and the connection conveyor 34 is a third position where the workpiece X can be conveyed toward the first main line ML1, and the connection conveyor 34 after being rotated approximately 90 ° from the third position. A second rotary transport device 36 that can change the work target product X to a fourth position where the work target product X can be transported is provided, and the first transport line 10 (first main line ML1) or the second transport device 36 is provided as necessary. The work target product X can be transported to the second transport line 11 (second main line ML2).

  Each of the supply conveyor 32 and the connection conveyor 34 is of the roller conveyor type as described above, and its operation and operation stop are controlled by the control means 50. Here, the control means 50 controls the supply conveyor 32 to stop while the seventh detection sensor 37 provided in the second rotary transfer device 36 detects the work target product X. Yes. Then, the work target product X is transported from the second rotary transport device 36 toward the first transport line 10 (first main line ML1) or the second transport line 11 (second main line ML2). When the seventh detection sensor 37 no longer detects the work target product X, the supply conveyor 32 is operated to move the work target product X to the second rotary transfer device 36.

  Specifically, the control means 50 compares the number of working areas SA in the first and second transport lines 10 and 11 identified by the identifying means 54 and responds to the ratio of the number of working areas SA. The number of work target articles X supplied to the first and second main lines ML1 and ML2 is adjusted. That is, in the embodiment, as described above, three work areas SA are operating in the first transfer line 10, and two work areas SA are operating in the second transfer line 11, so that the operation is always performed. The supply number of the work target product X to the first transfer line 10 and the second transfer line 11 is adjusted so that the ratio of the numbers (ie, 3 to 2) is obtained. As for the supply order, after supplying the three work target products X to the first transfer line 10 (first main line ML1), the two work target products X to the second transfer line 11 (second main line ML2). As a whole, the supply of the work target product X to both the main lines ML1 and ML2 is controlled so as not to be biased.

  In addition, when a predetermined condition is satisfied, the control unit 50 includes a first area corresponding to the work area SA operating on the most downstream side of the first transfer line 10 stored in the storage unit 52. The number of standbys in a specific standby area TA (third standby area TA3 in the embodiment) and the second specific standby area TA (corresponding to the work area SA operating on the most downstream side of the second transfer line 11) In the embodiment, the number of standbys in the fifth standby area TA5) is compared, and the work target product X can be preferentially supplied to any of the main lines ML1 and ML2 to which the specific standby areas TA3 and TA5 having a small number of standbys belong. The supply line 30 is controlled to operate. Here, the “predetermined condition” includes a point where a certain time has elapsed, or a point in time when the number of waiting in any specific waiting area TA3, TA5 reaches the maximum number (that is, the waiting number “3”), or any other arbitrary Each time the set condition is satisfied, the number of standbys in both specific standby areas TA3 and TA5 is compared, and the work target product for each of the transfer lines 10 and 11 (main lines ML1 and ML2) The supply number of X is adjusted.

(About the unloading line)
Since the carry-out line 40 has basically the same configuration as that of the inspection line KL, members having the same functions are described with the same reference numerals. The carry-out line 40 is provided below the main lines ML, and is provided below the two first collection lines 42 and 42 for conveying the work completion product Y to a shipping process (not shown) and the sub-lines SL. And a second recovery line 44 joined to the first recovery lines 42 and 42 (see FIG. 2). Here, each of the first recovery lines 42 is configured by connecting the first rotary transfer device 13 and the first transfer device 16, and the first recovery line 42 is first connected to the second recovery line 44. The rotary conveyance device 13 is arranged.

  That is, by positioning the first rotary transport device 13 in the first recovery line 42 at the first position, the work completion product Y can be transported along the first recovery line 42, and the first By rotating the rotary transport device 13 to the second position, the work completion product Y transported by the corresponding second recovery line 44 can be received in the first recovery line 42. Note that two second transfer devices 20 are connected between the lift means 27 in the second recovery line 44 and the first rotary transfer device 13 in the first recovery line 42.

  Here, the first recovery line 42 is provided with an eighth detection sensor 45 for detecting the work completed product Y at a position corresponding to the top and bottom of the third standby position in the standby area TA of each main line ML. The second recovery line 44 is provided with a ninth detection sensor 46 for detecting the work completion product Y at a position corresponding to the third transport device 23 in the sub-line SL and above and below. Then, the work completion product Y is preferentially carried out from the collection lines 42 and 44 corresponding to the detection sensors 45 and 46 that have detected the work completion product Y before any of the eighth detection sensor 45 and the ninth detection sensor 46. The first rotary transfer device 13 is rotated as described above.

  Specifically, when the eighth detection sensor 45 of the first collection line detects the work completion product Y before the ninth detection sensor 46 of the second collection line 44, each of the second collection lines 44 The second transfer device 20 is stopped, and the first rotary transfer device 13 is positioned at the first position to transfer the work completion product Y on the first recovery line 42 to the shipping process. On the other hand, when the ninth detection sensor 46 of the second recovery line 44 detects the work completion product Y before the eighth detection sensor 45 of the first recovery line 42, each first The transport device 16 is stopped to stop the transport on the first recovery line 42, and the first rotary transport device 13 is rotated to the second position so that the work completion product Y on the second recovery line 44 is the first. The first rotary transfer device 13 is rotated to the first position after the receipt, and the transfer in the first recovery line 42 is resumed and transferred to the shipping process. Yes.

  Next, an example of the control mode of the supply line KL and the transport lines 10 and 11 will be described with reference to FIGS.

(About supply of work items from the supply line to each transfer line)
The work target product X for which the assembly of various parts has been completed in the previous process is sequentially transported toward the inspection line KL by operating the supply line 30 based on the work target product supply process shown in FIG. First, it is determined whether or not the seventh detection sensor 37 provided in the second rotary transfer device 36 located on the downstream side of the supply conveyor 32 has detected the work target product X (step S101). At this time, when the seventh detection sensor 37 does not detect the work target product X, the work target product supply process is finished as it is. When the seventh detection sensor 37 detects the work target product X, the process proceeds to step S102 to determine whether or not a predetermined condition such as a predetermined time is satisfied. If the predetermined condition is not satisfied, the step is performed. The process proceeds to S103, and if the predetermined condition is satisfied, the process proceeds to Step S106. That is, in the work object supply process, the process after step S103 is always performed, and the process after step S106 is performed every time a predetermined condition is satisfied.

  In step S103, the operating number of the work area SA in the first transfer line 10 identified by the identification unit 54 is acquired, and the operating number of the work area SA in the second transfer line 11 is acquired (step S104). ), The work target product X is supplied to the first main line ML1 and the second main line ML2 according to the ratio of the number of working areas SA in each of the transfer lines 10 and 11 (step S105). Specifically, as described above, three work areas SA are operating in the first transfer line 10, whereas two work areas SA are operating in the second transfer line 11. The ratio between the supply number of the work target product X to the first transfer line 10 (first main line ML1) and the supply number of the work target product X to the second transfer line 11 (second main line ML2) is 3: 2. Then, the supply line 30 is activated.

  Thus, the supply number of the work target product X to each of the transfer lines 10 and 11 (each of the main lines ML1 and ML2) is set in accordance with the ratio of the number of working areas SA in the first and second transfer lines 10 and 11. By adjusting, the supply ratio of the work target product X to each operating work area SA can be made uniform, so that there is an advantage that the supply efficiency of the work target product X to each of the transfer lines 10 and 11 can be improved. . In addition, since it is set to supply the two work target products X to the second main line ML2 after supplying the three work target products X to the first main line ML1, as a whole, to both the main lines ML1 and ML2. The supply of the work target product X is not biased, and the production efficiency is not lowered.

  When the process proceeds from step S102 to step S106, the third standby area TA3 (first specific standby area) in the first transport line 10 (first main line ML1) stored in the storage unit 52 is stored. ) And the standby number of the fifth standby area TA5 (second specific standby area) in the second transport line 11 (second main line ML2) (step S106, step S107). Then, the acquired number of standbys in the third standby area TA3 and the number of standbys in the fifth standby area TA5 are compared (step S108). If the number of standbys in both the standby areas TA3 and TA5 is equal to or greater than the same, the step S103 is performed. Then, the work target product X is supplied in accordance with the ratio of the number of working areas SA in each of the transfer lines 10 and 11.

  On the other hand, if it is determined in step S108 that the number of standbys in the third and fifth standby areas TA3 and TA5 is not the same, the process proceeds to step S109, and the number of standbys in the third standby area TA3 is equal to that in the fifth standby area TA5. It is determined whether the number is smaller than the number of waiting. When the number of standby in the third standby area TA3 is smaller, the work target product X is supplied toward the first transfer line 10 (first main line ML1) (step S110), and the third standby area When the number of standbys of TA3 is larger, the work target product X is supplied toward the second transfer line 11 (second main line ML2) (step S111).

  In this way, the work target product X is preferentially supplied to the transport lines to which the standby areas TA3 and TA5 with a small number of standbys belong, so that the transport lines 10 and 11 (main line Since the work target product X can be supplied to ML1, ML2), the production efficiency can be improved. Further, every time a predetermined condition such as the passage of a predetermined time is satisfied, the number of waiting in the third and fifth waiting areas TA3 and TA5 is compared, and the conveying line that preferentially supplies the work target product X. 10, 11 (main lines ML1, ML2) are reviewed, so that the number of waiting in each waiting area TA of both conveying lines 10, 11 can always be kept substantially equal. In particular, even when the work speed varies depending on the skill level of the operator, such as the inspection work shown in the embodiment, the work target product X is supplied to each work area SA according to the work speed. Thus, there is an advantage that the working efficiency can be greatly improved.

(About the transfer of work target items in each transfer line)
Next, the conveyance of the work target product X supplied from the supply line 30 to each conveyance line (main line) to the work area SA will be described. In addition, in the said 1st conveyance line 10 and the 2nd conveyance line 11, it is the same regarding the conveyance control of the work target product X to the work area SA provided in each, and the said control means 50 is the said waiting area TA. With each unit as one unit, the same work object transport process (see FIG. 11) is performed for each standby area TA.

  As shown in FIG. 11, first, it is determined whether or not there is a work target product X at the first standby position (first rotary transfer device 13) in the standby area TA (step S201). That is, when the first detection sensor 14 provided in the first rotary conveyance device 13 detects the work target product X, the process proceeds to step S202, and the first detection sensor 14 detects the work target product X. If not, the process proceeds to step S207 described later. In step S202, it is determined whether or not the work target product X exists in the second transport device 20 in the subline SL corresponding to the standby area TA. That is, when the fourth detection sensor 21 provided in the second transfer device 20 does not detect the work target product X, the process proceeds to step S203, and the fourth detection sensor 21 detects the work target product X. In this case, the process proceeds to step S212 described later. In other words, when the work in the work area SA is completed and the work target product X is transferred from the second transfer device 20, the process proceeds to step S203, and the second operation is being performed in the work area SA. When the work target product X is waiting on the transfer device 20, the process proceeds to step S212.

  In step S203, the corresponding first rotary transfer device 13 is rotated to the second position, and the work object is transferred from the first rotary transfer device 13 (first standby position) to the second transfer device 20. The product X is transported (step S204). Then, after subtracting 1 from the standby number of the work target product X stored in the storage means 52 with respect to the standby area TA (step S205), the process proceeds to step S206 and the first rotary transfer device 13 is moved to the first. The position is rotated, and then the process proceeds to step S207. That is, when the work target item X is not waiting at the first standby position, the process proceeds to step S207. As described above, since the first rotary transfer device 13 is configured to be rotatable to the first position and the second position, the work target product X transferred along each main line ML is automatically handled. It can be sent toward the subline SL. That is, there is an advantage that the work target product X can be efficiently supplied to the work area SA provided in each subline SL.

  In addition, a second transport device 20 that can be individually activated and deactivated is provided in each of the sublines SL, and the work target product X from the first rotary transport device 13 is once on standby in the second transport device 20. By doing so, the work target product X can be reliably supplied to the corresponding work area SA, and the productivity can be further improved. In particular, in the configuration in which the first rotary transport device 13 is rotated to the first position and the second position as in the embodiment, when the work target product X in the standby area TA is sent to the subline SL, as described above. Since the operation | movement which displaces the 1st rotary conveying apparatus 13 from a 1st position to a 2nd position is required, the work target product X cannot be rapidly supplied with respect to the subline SL. Even in such a case, by providing the second transfer device 20, the work target product X that is made to wait in the second transfer device 20 can be quickly supplied to the work area SA, and further, After that, the work target product X is supplied to the second transfer device 20 to be put on standby, so that the production efficiency can be improved.

  In step S207, it is determined whether there is a work target item X at the second standby position. Specifically, when the second detection sensor 17 provided in the first transport device 16 corresponding to the second standby position detects the work target product X, the process proceeds to step S208 and the first transport is performed. The apparatus 16 is operated to transport the work target item X at the second standby position to the first standby position (first rotary transport device 13), and the process proceeds to step S209. If the second detection sensor 17 has not detected the work target product X, the process proceeds to step S209. In step S209, it is determined whether or not there is a work target item X at the third standby position. That is, when the third detection sensor 18 provided in the first transport device 16 corresponding to the third standby position detects the work target product X, the first transport device 16 is operated to perform the third operation. The work target product X at the standby position is conveyed to the second standby position (step S210), and when the third detection sensor 18 has not detected the work target product X, the process proceeds to step S211 and the work target product replenishment process is performed. (See FIG. 12).

  On the other hand, when it is determined in step S202 that the work object X is present in the second transport device 20, and the process proceeds to step S212, it is determined whether or not the work object X is present in the second standby position. That is, when the second detection sensor 17 provided in the first transfer device 16 corresponding to the second standby position detects the work target item X, the process proceeds to step S213 and the work target item X is set to the third standby position. It is determined whether or not there is. In step S212, if there is no work target product X at the second standby position (the second detection sensor 17 has not detected the work target product X), the process proceeds to step S209 to reach the third standby position. It is determined whether or not there is a work target product X, and if there is a work target product X at the third standby position as described above, the work target product X at the third standby position is transported to the second standby position. (Step S210) When there is no work target product X at the third standby position, the process proceeds to Step S211 to perform work target product replenishment processing (see FIG. 12). In step S213, when there is a work target item X at the third standby position (that is, the third detection sensor 18 provided in the corresponding first transport device 16 detects the work target item X). When the work target product transport process is completed and the third detection sensor 18 has not detected the work target product X, the process proceeds to step S210, and the work target product replenishment process (see FIG. 12) is performed.

  Thus, by providing the standby area TA for waiting for the work target product X at the branch position of each main line ML with respect to the sub line SL, the work for the work target product X is completed in the work area SA in any of the sub lines SL. In this case, since the next work target product X can be sent out quickly to the work area SA (subline SL), the production efficiency of the production line can be improved. In addition, since the work target product X is preferentially placed on standby at a standby position located downstream in the standby area TA, the work target product X is placed on the corresponding subline SL or the downstream standby area TA. Since it can be sent out promptly, the supply efficiency of the work target product X to the standby area TA on the downstream side or from all the standby areas TA to the corresponding subline SL can be improved.

  In addition, since each of the standby areas TA is configured to be able to wait for up to three work target products X, even if the work target product X is replenished to the downstream standby area TA, the upstream standby The work target product X can be left in the area TA, and even when it is necessary to supply the work target product X to the corresponding work area SA, it is possible to respond quickly. Furthermore, by making a plurality of work target articles X stand by in each standby area TA, the work target articles X supplied from the supply line 30 can be sequentially stocked in each standby area TA. The supply of the work target product X can be performed smoothly. That is, since it is not necessary to stop the supply line 30 as much as possible, the work in the previous process is not adversely affected.

(Replenishment of work items from the upstream standby area)
As shown in FIG. 12, in the work object replenishment process, a standby area TA (hereinafter referred to as a reception-side standby area TA) to be replenished with the work object X stored in the storage means 52, The waiting numbers in the waiting area TA located upstream (hereinafter referred to as sending-side waiting area TA) are compared (step S301). Here, when the waiting number in the waiting area TA on the sending side is smaller, the work target product X in the waiting area TA on the receiving side until the waiting number in the waiting area TA on the sending side becomes the same number. Is temporarily stopped (step S302, step S303). When the number of waiting in the waiting area TA on the sending side and the receiving side becomes the same, the process proceeds to step S304 to determine whether or not the first rotary transfer device 13 in the waiting area TA on the sending side is in the first position. After the first rotary transport device 13 is displaced to the first position, the work target product X is transported from the first rotary transport device 13 to the standby area TA on the receiving side (step S305). When the work object X is conveyed from the waiting area TA on the sending side, 1 is subtracted from the waiting number in the waiting area TA on the sending side stored in the storage means 52 (step S306). If it is determined in step S301 that the number of standbys in the waiting area TA on the sending side is equal to or greater than the number of standbys in the waiting area TA on the receiving side, the process proceeds directly to step S304.

  In this way, by comparing the number of standbys in the waiting area TA adjacent to the sending side and the receiving side and transporting the work target product X, an excessive supply of the work target product X to the receiving side standby area TA, and It is possible to prevent a shortage of work target items X in the waiting area TA on the sending side. That is, since the work target product X can be uniformly supplied to the work area SA corresponding to each standby area TA, there is an advantage that it is possible to prevent the work load in the work area SA from being varied.

  Next, in step S307, it is determined whether or not the number of waiting in the waiting area TA on the receiving side is “0”. If “0”, the work object X is transferred to the first rotary transfer device 13 ( The transport devices 13 and 16 are controlled to be replenished to the first standby position (step S308). If the number of waiting in the waiting area TA on the receiving side is not “0”, the process proceeds to step S309 to determine whether or not the number of waiting is “1”. Each transport device replenishes the product X to the second standby position and replenishes the work target product X to the third standby position when the standby number is not “1” (that is, when the standby number is “2”). 13 and 16 are controlled (steps S310 and S311). When the detection sensors 14, 17, and 18 for the standby position to be replenished detect the work target product X, 1 is added to the standby number in the standby area TA on the receiving side stored in the storage means 52 (step S312). When the waiting number reaches the upper limit, the work target product replenishment process ends. In addition, regarding the replenishment of the work target product X to the first standby area TA1 and the fourth standby area TA4 located on the most upstream side in each main line ML1, ML2, the work target product X supplied from the supply line 30 is used. Based on the processing from step S307 to step S312, one of the first to third standby positions is replenished.

  In this way, the work target product X that has been waiting in any one of the waiting areas TA is sent to the downstream side of the main line ML or the corresponding subline SL, and “free” is present in any of the first to third waiting positions. When this occurs, the work target product X is replenished from the standby area TA located upstream of the standby area TA, so the work target product X is smoothly replenished to the work area SA located downstream. Can do. That is, even when a plurality of work areas SA are provided for the main line ML, the work target product X can be transported to each work area SA without any delay, so that work efficiency can be improved. Accordingly, even when workers having different work capabilities are arranged in each work area SA, the work target product X can be supplied to each work area SA in accordance with the work ability. Is greatly improved. In addition, when providing a plurality of work areas SA, there is no need to unnecessarily increase the main line ML, so that there is an advantage that the problem of space can be solved without increasing the size of the production line.

  Further, as in the embodiment, only when the work target product X is sent from each of the standby areas TA to the downstream standby area TA or the corresponding subline SL, the number stored in the storage means 52 is decremented by one. When the detection sensors 14, 17, and 18 of the transfer devices 13 and 16 to be replenished detect the work target item X from the upstream standby area TA, the storage number of the storage means 52 is incremented by one. Thus, the standby number of the work target product X in each standby area TA can be accurately managed. That is, since the number of standbys of the work target product X is not increased or decreased depending on the movement of the work target product X in the same standby area TA, the standby number of each standby area TA can be accurately grasped, and There is an advantage that the supply of the work target product X can be uniformly supplied to each work area SA by preventing an excessive supply of the work target product X and a shortage of the work target product X in the upstream standby area TA. Further, when the detection sensors 14, 17, and 18 detect, the storage number of the storage means 52 is incremented by 1, so that when the work target product X is replenished to each standby area TA, the work target product X should be replenished. The position can be easily specified.

(About unloading completed products)
The work completion product Y that has completed the work in the work area SA is transported to the lift means 27 by the third transport device 23 and also transported to the unloading line 40 by the lift means 27 to be shipped. Carried to. In this way, since the work completion product Y is transported to the carry-out line 40 by the lift means 27, it is possible for the worker to save the work of moving the work completion product Y to the carry-out line 40 or the shipping process after the work is completed. Improvement is achieved.

  Further, when the work completion product Y is transported by the unloading line 40, the work being transported to the first recovery line 42 is completed at the joining position of the first recovery line 42 and the second recovery line 44 in the unloading line 40. There is a possibility that the product Y and the work completion product Y conveyed to the second collection line 44 may come into contact with each other. Therefore, in the embodiment, the eighth detection sensor 45 is provided in the first recovery line 42, and the ninth detection sensor 46 is provided in the second recovery line 44. Since the work completion products Y of the collection lines 42 and 44 that have detected the above are transported first, the work completion products Y can be transported smoothly.

For example, in the embodiment, two main lines are provided, but one or more main lines may be provided, and the number of sub-lines branching from the main line is limited to three as in the embodiment. Instead of this, it is possible to branch two or more sublines from one main line. In the embodiment, each work area is configured to be able to wait for three work objects. However, the present invention is not limited to this, and one, two, or four or more work objects may be made to wait.

When the work object is sent to the work area, the respective transport means are controlled to replenish the work object from the upstream standby area with respect to the work area, and the work object is always placed in the work area. If the product is made to wait, it can be changed arbitrarily. Similarly, when a work target product is sent from any one of the standby areas to a downstream standby area or a corresponding subline, the work target product in the standby area to be replenished with the work target product stored in the storage means is stored. If the number of waiting for work items in the standby area located upstream is smaller, the number of work items in the waiting area located one upstream is compared. Is temporarily stopped, and after the number of standby work items in the standby area located on the upstream side becomes the same number, the respective work items are replenished to the standby area where the work target product should be supplied. If the operation of the conveying means is controlled, it is possible to adopt a control mode different from the embodiment.

  The control mode of the supply line that supplies the work target product to a plurality of transport lines (main lines) is not limited to that of the embodiment, and can be changed as required. That is, based on the identification information of the identification means, the number of working areas in each transfer line is compared, and the number of work items supplied to each main line is adjusted according to the ratio of the number of working areas. do it. Similarly, the transport means of each main line is controlled so that the number of standby work items in each standby area stored in the storage means is equalized, and work in a predetermined standby area in each transport line is established when a predetermined condition is satisfied. By comparing the number of standbys of the target product and supplying the work target product preferentially to the main line of the transfer line to which the standby area with a small number of standbys belongs, the same effect as the embodiment can be obtained.
