Description

  The present invention relates to a gaming machine manufacturing line, and more particularly to a gaming machine manufacturing line configured to transport a product to be transported for which a required operation has been completed via the transporting line.

Generally, at a gaming store, when a gaming machine is introduced and used for a predetermined period of time, even if it is still usable, it is replaced with another gaming machine so that the player does not get bored. At this time, from the viewpoint of waste reduction and effective use of resources, the old game machines that are discharged from the game stores as industrial waste are collected, and various parts attached to the collected game machines are replaced with new ones. Reuse as much as possible in gaming machines is performed (see, for example, Patent Document 1). The state of the gaming machine (parts) collected depends on the usage status of the gaming machine at the gaming store, etc., varies from one gaming store to another. For this reason, gaming machines (parts) that have been manufactured by reusing inferior gaming machines (parts) for gaming stores (parts) that are used for reuse in relatively good conditions. If the product is delivered, the amusement store will be dissatisfied. Therefore, when a gaming machine (part) is reused, consideration is given to delivering a reused product manufactured using that gaming machine (part) to the gaming store where the gaming machine (part) is collected. Yes.

It may be determined that the product (50) to be transported on the transport line (10) is retracted to the retreat line (12, 14) until the reading position closest to the selected transport means (18) is reached.

Then, according to the gaming machine production line according to 請 Motomeko 1 of the present application, the transport target article being conveyed by the conveyor line, if different types of transport target product was contaminated through the selection conveying means Since different types of products to be transported can be temporarily retracted to the evacuation line, only the same type of products to be transported can be reliably transported to the unloading line, and the products to be transported evacuated to the evacuation line are required. Accordingly, it can be conveyed to the carry-out line via the selective conveying means. In this way, different types of products to be transported are temporarily retracted to the evacuation line, and then transported to the unloading line together with the same type of products to be transported, so that the products to be transported are automatically sorted by type. Therefore, it is possible to improve work efficiency and reduce work mistakes as compared with the case where the worker performs manual work. In addition, since the sorting work is automatically performed, a certain work efficiency can be ensured. Furthermore, the identification information given to the product to be conveyed is read by the first reading means provided on the conveyance line, the second reading means provided on the retreat line, and the third reading means provided on the carry-out line, Based on the identification information, it is possible to automatically carry out the sorting work of the products to be transported. That is, compared with the case where sorting work is performed manually, there is an advantage that work efficiency can be greatly improved and work errors can be reduced.

In addition, according to the gaming machine manufacturing line according to claim 2 , by transferring the product to be transported in the evacuation line to the carry-out line with priority over the product to be transported in the transport line, the product to be transported is in the evacuation line. In addition to preventing stagnation, it is possible to prevent the product to be transported from being retracted to the retreat line.

Furthermore, according to the gaming machine production line according to claim 3 , since the transport target product of a different type from the transport target product transported last time in the carry-out line can be retracted to the retreat line, it can be reliably sorted. In the case where the product to be transported retracted to the retreat line is the same as the product to be transported last time on the unloading line, the product to be transported on the retreat line can be preferentially sent to the unloading line.

Furthermore, according to the gaming machine manufacturing line according to claim 4 , the identification information given to the product to be transported is composed of a plurality of pieces of rank information having different priorities, so that the rank information having a higher priority. Can be preferentially carried out to the carry-out line when there is a coincident conveyance target product on the upstream side of the conveyance line.

According to the gaming machine manufacturing line according to claim 5 , the transport target product on the transport line and the transport target product on the evacuation line match the transport target product transported last time on the carry-out line with higher priority information. Since the product to be transported is configured to be sent to the carry-out line, a finer sorting operation can be performed. In addition, if the order information of the same priority order is the same for the product to be transported on the transport line and the product to be transported on the evacuation line, the priority order of the product to be transported on the unload line is the same priority, Since the product is sent to the carry-out line, it is possible to prevent the product to be transported from staying in the retreat line and to prevent the product to be transported from being retreated to the retreat line.

According to the gaming machine manufacturing line of claim 6 , the highest priority order information of the identification information of the product to be transported at the reading position closest to the selected transport means in the transport line is the storage means. The storage means stores the highest priority order information of the identification information of the products to be transported at other reading positions on the transport line even if the corresponding order information in the stored identification information does not match. When the corresponding order information in the identification information is matched, the transport target product on the transport line is retracted to the retreat line, so that the transport target product with the higher priority is preferentially sent to the unload line. This enables accurate and fine sorting of products to be transported.

  Next, the gaming machine production line according to the present invention will be described below with reference to the accompanying drawings by way of preferred embodiments.

Further, above the lines 10, 12, 14, 16 and the rotary conveying device 18, support means (not shown) is provided for supporting the upper part of the object 50 to be conveyed in a standing posture. Thus, the product to be transported 50 is prevented from overturning.

  Here, based on the control of the control means 36, the rotary transport device 18 can receive a transport target product 50 transported by the transport line 10 (first position, see FIG. 3A). Between the first retraction line 12 and the first retraction line 12 and the second retraction line 14 and the first retraction line 14. 2nd delivery position (second position, see FIG. 3 (b)) and delivery position (3rd position, see FIG. 3 (a)) where the product 50 can be delivered to the carry-out line 16 It is configured to be able to rotate (move) between. In addition, the said rotary conveying apparatus 18 is comprised so that it can rotate in the clockwise and counterclockwise arbitrary directions in FIG. 1, and can rotate each roller part forward and backward. That is, by rotating the rotary conveying device 18 clockwise or counterclockwise, the receiving position, each delivery position, and the delivery position are displaced. In the embodiment, the rotary transport device 18 is in the same posture at the receiving position and the sending position, and at the first delivery position and the second delivery position (see FIGS. 3A and 3B). ). Accordingly, by rotating the rotary transport device 18 based on the control means 36, the product 50 to be transported received from the transport line 10 at the receiving position and the sending position is sent to the unloading line 16 as it is. obtain. Further, the rotary conveying device 18 is rotated based on the control means 36, and at the first delivery position and the second delivery position, the direction of rotation of the roller portion is reversed, so that the article 50 to be conveyed is first and In addition to being able to be retracted to the second retreat lines 12, 14, the retracted conveyance target product 50 can be received (can be delivered).

(About the transfer line)
The transport line 10 extends linearly so that its downstream end is connected to the left end of the rotary transport device 18 in FIG. 1, and the transport line 10 is operated based on the control of the control means 36. The product to be transported 50 can be transported to the rotary transport device 18. Further, conveyance reading sensors (first reading means) 21 to 26 capable of reading the identification information given to the conveyance target product 50 are arranged at six locations along the extending direction of the conveyance line 10, and each conveyance is performed. Identification information (hereinafter referred to as read information) of the conveyance target product 50 read by the reading sensors 21 to 26 is output to the determination means 40 of the control means 36. In the following description, the first conveyance reading sensor 21, the second conveyance reading sensor 22, the third conveyance reading sensor 23, the fourth conveyance reading sensor 24, in order from the conveyance reading sensor closest to the rotary conveyance device 18. The fifth conveyance reading sensor 25 and the sixth conveyance reading sensor 26 are designated as well, and the positions at which the first to sixth conveyance reading sensors 21 to 26 read the identification information of the conveyance target product 50 are first to first correspondingly. This is referred to as 6 reading position. Further, when the first transport reading sensor 21 reads the identification information of the transport target product 50, the control means 36 controls to stop the transport line 10.

(Evacuation line)
The first and second evacuation lines 12 and 14 are formed to have a size capable of stopping and holding one conveyance target product 50, and the lower end portion of the first evacuation line 12 in FIG. The upper end of the second retreat line 14 is arranged so as to connect to the lower end of the rotary transfer device 18. Each of the first and second evacuation lines 12 and 14 is individually controlled to be operated and stopped by the control means 36, and the first and second evacuation lines 12 and 14 are operated. The retracted product to be transported 50 can be transported to the rotary transport device 18. Further, on the first and second evacuation lines 12 and 14, evacuation reading sensors (second reading means) 31 and 32 that can read the identification information given to the conveyance target product 50 are respectively arranged correspondingly. Thus, the identification information (hereinafter referred to as “evacuation information”) read by each of the retraction reading sensors 31 and 32 is output to the determination means 40 of the control means 36. In the following description, the sensor provided in the first retraction line 12 is referred to as a first retraction reading sensor 31, the sensor provided in the second retraction line 14 is referred to as a second retraction reading sensor 32, and these A position at which each of the retraction reading sensors 31 and 32 reads the identification information of the conveyance target product 50 is referred to as a retraction position. That is, the product to be transported 50 retracted to the first retreat line 12 or the second retreat line 14 is temporarily waiting at each corresponding retreat position.

(About the unloading line)
As shown in FIG. 1, the carry-out line 16 extends linearly so that the upstream end is connected to the right end of the rotary transfer device 18, and operates the carry-out line 16 based on the control of the control means 36. By doing so, the product 50 to be transported from the rotary transport device 18 can be transported to the shipping line. Further, an unloading reading sensor (third reading means) 34 for reading the identification information given to the object to be conveyed 50 is provided in the vicinity of the upstream end of the unloading line 16 (near the rotary conveying device 18). Yes. The identification information read by the carry-out reading sensor 34 is set to be output to the storage means 38 (see FIG. 2) of the control means 36 and stored in the storage means 38 as storage information. The information stored in the storage means 38 is set so as to be updated every time the carry-out reading sensor 34 reads the identification information of the product 50 to be conveyed, and the storage means 38 uses the carry-out line 16 for the shipment process. The identification information (first and second order information) of the latest transported product 50 that has been transported is always stored.

  The identification information includes shipping destination information (rank information) indicating the shipping destination hole of the transport target product 50 and spec information (rank information) indicating the specifications of the transport target product 50, such as a two-dimensional code. It is given to the object to be transported 50 using various codes, IC tags, and other conventionally known means. Here, in order to simplify the shipping operation of the conveyance target product 50, it is preferable to group the conveyance target products 50 for each of the items with the same shipment destination, and further classify them into items with the same specifications. That is, the identification information is composed of two pieces of rank information having different priorities. In the following description, shipment destination information having a high priority is referred to as first rank information, and specification information having a low priority is denoted as a second rank. This is referred to as information. Each of the conveyance reading sensors 21 to 26, each of the retraction reading sensors 31, 32, and the unloading reading sensor 34 reads each of the first and second order information.

Here, each of the lines 10, 12, 14, 16 and the rotary transport device 18 includes a transport source line that is a transport source of the transport target product 50 by the control unit 36, and a transport destination of the transport target product 50. It operates based on the determination of the transport destination line. When the control unit 36 determines the transfer source line and the transfer destination line, the determination unit 40 stores the storage information (first and second order information) stored in the storage unit 38. The reading information (first and second rank information) read by each of the conveyance reading sensors 21 to 26 and the evacuation information (first and second rank information) read by each of the evacuation reading sensors 31 and 32 are collated. Is set. In other words, based on the collation result of the determination unit 40, the control unit 36 selects either the transport target product 50 transported by the transport line 10 or the transport target product 50 retreated to each of the retreat lines 12 and 14. In addition to determining whether to carry to the carry-out line 16, it is determined whether or not the object to be conveyed 50 conveyed on the conveyance line 10 is to be retreated to the retreat lines 12 and 14.

  When at least one of the first evacuation reading sensor 31 and the second evacuation reading sensor 32 is reading the evacuation information, the determination means 40 determines the first rank information and the second rank information of the evacuation information. The first rank information and the second rank information of the stored information stored in the storage means 38 are sequentially collated from the top in accordance with the priority order (that is, the second rank information is collated after collating the first rank information). Yes) If there is order information that does not match between the saved information and the stored information, the first order information and the second order information of each read information read by the first to sixth transport reading sensors 21 to 26 are displayed. The first order information and the second order information of the stored information are sequentially collated from the top in accordance with the priority order. Then, as a result of collating the first and second order information from the top of the priority order, the product to be transported is based on the lowest priority order that matches each of the saved information, the stored information, and the read information and the stored information. 50 transfer source lines and transfer destination lines are determined (detailed in paragraphs [0029] to [0057]).

  Here, when the control means 36 determines to transport the transport target product 50 of the transport line 10 to the carry-out line 16 (that is, when the transport line 10 is a transport source line and the transport line 16 is a transport destination line). ), The rotary transport device 18 is rotated to the receiving position (sending position) to receive the product to be transported 50 from the transport line 10, and the transport target product 50 is transported from the rotary transport device 18 in the same position. Each of the lines 10, 12, 14, 16 and the rotary transfer device 18 is controlled to be sent to the printer 10. Further, when the control means 36 determines to retract the product 50 to be transported on the transport line 10 to the first or second retreat lines 12 and 14 (that is, the transport line 10 is the transport source line, the first or second 2, when the retreat lines 12 and 14 are transport destination lines), the rotary transport device 18 is rotated to the receiving position to receive the product 50 to be transported from the transport line 10, and then the rotary transport device 18 is moved to the first position. Alternatively, each of the lines 10, 12, 14, 16 and the rotary transfer device 18 are controlled to rotate so as to rotate to the second delivery position and send the conveyance target product 50 to the corresponding retreat lines 12, 14. Further, when the control means 36 decides to convey the product 50 to be conveyed on the first or second evacuation line 12, 14 to the carry-out line 16 (that is, the first or second evacuation line 12, 14 is transferred from the conveyance source). And the unloading line 16 as a transfer destination line), the rotary transfer device 18 is rotated to the first or second delivery position, and the transfer target product 50 is received from the corresponding evacuation lines 12 and 14, and thereafter The operation is controlled so that each of the lines 10, 12, 14, 16 and the rotary transport device 18 is controlled so that the rotary transport device 18 is rotated to the delivery position and the product 50 to be transported is sent to the carry-out line 16. Is done.

  In other words, in the embodiment, the rotary transport device 18 can be rotated to the receiving position, each delivery position, and the delivery position, so that the product 50 to be transported by the transport line 10 can be transferred to the first retreat line 12, 2 It can be arbitrarily conveyed to either the evacuation line 14 or the carry-out line 16, and the conveyance target product 50 temporarily evacuated to the first evacuation line 12 and the second evacuation line 14 can be conveyed to the carry-out line 16. It is configured. As described above, when the conveyance target products 50 of different types (shipping destinations and specifications) are mixed in the conveyance target products 50 conveyed by the conveyance line 10, the different types of conveyance target products 50 are designated as the first. Alternatively, it is possible to temporarily retract to the second retreat lines 12 and 14 and then transport the same type of transport target product 50 to the shipping process. That is, since the transport target product 50 can be automatically sorted and transported to the shipping line for each type, work efficiency can be improved as compared with the case where the worker manually sorts the transport target product 50. It becomes possible to reduce work mistakes.

  Next, the determination of the transfer source line and the transfer destination line of the transfer target product 50 by the control means 36 will be described.

(When the product to be transported is retracted to the first or second retreat line)
“When the save information and the stored information match each of the first and second rank information”
As a result of the collation by the determination unit 40, the control unit 36 has the first and second rank information (all rank information) of the evacuation information read by the first or second evacuation reading sensors 31 and 32 as described above. When the storage unit 38 matches the first and second rank information of the stored information (see pattern 1 in Table 1), it corresponds to the retraction reading sensors 31 and 32 that read the corresponding retraction information. It is determined that the product 50 to be transported in the evacuation lines 12 and 14 is transported to the carry-out line 16 (the transport source line is the first or second evacuation line 12 and 14, and the transport destination line is the carry-out line 16), and the paragraph number [0027 ] Is set to control the operation of each of the lines 10, 12, 14, 16 and the rotary transfer device 18 in accordance with the conditions described in FIG. 4 (see the flow of steps S111 to S116 in FIG. 4 described later). That is, when the same type of transport target product 50 having the same shipping destination and specifications as the transport target product 50 transported toward the previous shipping process by the unloading line 16 is in the first or second retreat line 12, 14. The transport target product 50 on the evacuation lines 12 and 14 is controlled to be transported to the unloading line 16 with priority over the transport target product 50 on the transport line 10. Thus, the conveyance target product 50 is prevented from staying in the retreat lines 12 and 14, and the conveyance target product 50 is prevented from being unable to be retreated to the retreat lines 12 and 14.

“When only the first rank information matches between the saved information and the stored information”
As a result of the collation by the determination means 40, the rank information having the lowest priority order in which any one of the saved information is matched only in the stored information and the first rank information and each read information and the stored information is matched. In the case of the first rank information (see pattern 2 in Table 1), it is determined that the conveyance target product 50 of the corresponding evacuation line 12, 14 is conveyed to the carry-out line 16 (the conveyance source line is the first or second evacuation line). 12 and 14, the transfer destination line is set to control the operation of each of the lines 10, 12, 14 and 16 and the rotary transfer device 18 in accordance with the conditions described in paragraph [0027]. (See steps S112 → S122 → S123 in FIG. 4 described later). That is, as a result of collation from the top in accordance with the priority order, the lowest priority order information that matches the saved information and the stored information is the lowest priority order information that matches any of the read information and the stored information. Is determined to be transported to the carry-out line 16. In other words, when the number of rank information that matches the read information and the storage information from the top of the priority order is the same as the number of rank information that matches the save information and the storage information from the top of the priority order. In addition, the products 50 to be conveyed on the first or second evacuation lines 12 and 14 are conveyed to the carry-out line 16. As described above, when the transport target product 50 on the transport line 10 and the transport target product 50 on the evacuation lines 12 and 14 match only the first rank information with the transport target product 50 transported last time on the carry-out line 16. In this case, the conveyance target product 50 in the evacuation lines 12 and 14 is preferentially sent to the carry-out line 16, so that the conveyance target product 50 is prevented from stagnation in the evacuation lines 12 and 14, and the evacuation line. This prevents the conveyance target product 50 from being retracted to 12,14.

Similarly, as a result of the collation by the determination means 40, any of the saved information matches only with the stored information and the first rank information, and none of the read information matches with the stored information at least with the first rank information. In the case (refer to pattern 3 in Table 1), it is determined that the conveyance target product 50 of the corresponding evacuation line 12, 14 is conveyed to the carry-out line 16 (the conveyance source line is the first or second evacuation line 12, 14). The transport destination line is set to carry out operation control of each of the lines 10, 12, 14, 16 and the rotary transport device 18 in accordance with the conditions described in the paragraph number [0027]. 4) (see steps S112 → S122 → S123). That is, as a result of collation from the top in accordance with the priority order, the rank information that does not match between any of the saved information and the stored information has a lower priority than the rank information that does not match between the read information and the stored information, It is determined that the product to be transported 50 on the evacuation lines 12 and 14 is transported to the carry-out line 16. In other words, when the number of pieces of rank information that matches between the saved information and the stored information from the top of the priority order is larger than the number of rank information that matches the top order of priority between the read information and the stored information. In addition, the products 50 to be conveyed on the first or second evacuation lines 12 and 14 are conveyed to the carry-out line 16. In this way, in the transport target product 50 on the transport line 10 and the transport target product 50 on the evacuation lines 12 and 14, the higher priority ranking is given to the transport target product 50 transported last time on the carry-out line 16. Since the transport target products 50 of the evacuation lines 12 and 14 having the same information (the first order information is the same) are preferentially sent to the carry-out line 16, more detailed sorting work can be performed. ing.

  In addition, as a result of the collation by the determination means 40, any of the saved information matches only with the stored information and the first rank information, and any of the read information with the stored information and the first and second rank information (See pattern 4 in Table 1 below), the control means 36 determines whether or not the product to be transported 50 of the transport line 10 is retracted to the retreat lines 12 and 14. (See steps S112 → S122 → S124 in FIG. 4 described later). That is, as a result of collation from the top in accordance with the priority order, the lowest priority order information that matches the stored information with any of the saved information is the lowest priority order that matches the read information with any of the read information. When the priority is higher than the rank information (in this example, the first order information is used for the save information and the second order information is used for each read information), the transport target product 50 of the transport line 10 is set to the first or the first order information. It is determined whether or not to retreat to the second retreat lines 12 and 14. In other words, when the number of rank information that matches between the saved information and the stored information from the top of the priority order is smaller than the number of rank information that matches the top order of the priority between the read information and the stored information. In addition, it is determined whether or not the product to be transported 50 of the transport line 10 is retracted to the first or second retreat line 12 or 14.

  In this case, the reading information of the first conveyance reading sensor 21 that has read the conveyance target product 50 at the first reading position (that is, the reading position closest to the rotary conveyance device 18) is the storage information and the first information. Of the reading information of the second to sixth transport reading sensors 22 to 26 that read the transport target product 50 that does not match in each of the second order information and is in the second to sixth reading positions (other reading positions). If any of the stored information matches the first and second order information (see pattern A in Table 2), the transport target product 50 matches the stored information and the first and second order information. Until the first reading position is reached, the control means 36 determines that the product 50 to be transported on the transport line 10 is retracted to the retreat lines 12 and 14 (the transport source line is the transport line 10 and the transport destination line is First or second evacuation line 1 , 14), and each of the lines 10, 12, 14, 16 and the rotary transfer device 18 are controlled to operate according to the conditions described in paragraph [0027] (step SS202 → S205 in FIG. 5 described later). Refer to the flow of

  Similarly, the reading information of the first conveyance reading sensor 21 that has read the conveyance target product 50 at the first reading position matches only the first order information with the stored information, and the second to sixth reading positions (others) If any of the read information of the second to sixth transport reading sensors 22 to 26 that read the transport target product 50 at the read position) matches the stored information and the first and second order information (table 2), the transport target product 50 of the transport line 10 is retracted until the transport target product 50 whose stored information matches the first and second order information arrives at the first reading position. The control means 36 decides to retreat to 12, 14 (the conveyance source line is the conveyance line 10 and the conveyance destination line is the first or second evacuation line 12, 14), according to the condition described in paragraph [0027]. Each line 10, 12, 1 4, 16 and the rotary transfer device 18 are set to control the operation (see the flow of steps SS202 → S205 in FIG. 5 described later).

  That is, as in the embodiment, a plurality of reading positions where the identification information given to the conveyance target product 50 can be read is provided in the conveyance line 10, so that it is in any of the second to sixth reading positions. While the identification information of the conveyance target product 50 matches the stored information and the first and second order information, the identification information of the conveyance target product 50 at the first reading position is the storage information and at least the first and second items. If the order information does not match, the product to be transported 50 at the first reading position of the transport line 10 is retreated to the first or second retreat lines 12 and 14 to be shipped by the previous unload line 16. The conveyance target product 50 having the same first and second order information as the conveyance target product 50 conveyed to the process can be preferentially sent to the carry-out line 16, and the conveyance target product 50 is accurately and finely sorted. But It becomes possible. In the embodiment, the control means 36 moves the transport target product 50 of the transport line 10 to the retreat line 12, while the transport target product 50 is retracted to the first and second retreat lines 12, 14, respectively. When it is decided to retreat to 14, the notification means 42 (see FIG. 2) notifies the abnormality.

  When determining whether or not the product 50 to be transported on the transport line 10 is retracted to the retreat lines 12 and 14, each of the first and second order information of the read information read by the first transport reading sensor 21 is stored. When the information coincides with the first and second rank information (see pattern C in Table 2), the control means 36 determines to convey the conveyance target product 50 of the conveyance line 10 to the unloading line 16 (conveyance). The original line is the transport line 10, the transport destination line is the carry-out line 16), and the respective lines 10, 12, 14, 16 and the rotary transport device 18 are controlled in accordance with the conditions described in paragraph [0027]. It is set (see the flow of steps S202 → S203 in FIG. 5 described later). As described above, when the transport target product 50 transported to the shipping process by the previous unloading line 16 and the transport target product 50 having the first and second rank information coincide with each other at the first reading position, the matching transport target. Since the product 50 can be transported by the unloading line 16, the transport target product 50 can be accurately sorted.

“When the first order information does not match between the saved information and the stored information”
When the result of collation by the determination means 40 is that none of the saved information matches the stored information and the first rank information, and none of the read information matches the stored information and the first rank information (Refer to pattern 5 in Table 1), the control means 36 conveys the conveyance target products 50 on the retreat lines 12 and 14 corresponding to the retreat reading sensors 31 and 32 reading the retreat information to the carry-out line 16. Determined (the transport source line is the first or second evacuation line 12, 14 and the transport destination line is the carry-out line 16), and the lines 10, 12, 14, 16 and the rotation according to the conditions described in paragraph [0027] It is set to control the operation of each of the transporting devices 18 (see the flow of steps S111 → S118 → S104 in FIG. 4 described later). As described above, the transport target products 50 are required to be grouped at least for items that match the shipping destination (ie, the first order information), and when the shipping destination (ie, the first order information) does not match. There is no advantage to grouping. That is, there is no transport target product 50 whose transport destination (first rank information) coincides with the transport target product 50 transported to the shipping process last time by the unloading line 16 in the transport line 10 and the evacuation lines 12 and 14. If the target products 50 cannot be grouped by shipping destination, the transport target products 50 on the retreat lines 12 and 14 are transported to the unload line 16 with priority over the transport target products 50 on the transport line 10, thereby The conveyance target product 50 is prevented from staying in the lines 12 and 14 and the conveyance target product 50 is prevented from being unable to be retracted to the retreat lines 12 and 14.

  In addition, as a result of the collation by the determination means 40, none of the saved information matches the stored information and the first rank information, and any of the read information matches the stored information at least in the first rank information. When doing so (see pattern 6 in Table 1), as described above, the control means 36 determines whether or not the product to be transported 50 on the transport line 10 is retracted to the retreat lines 12 and 14. (Refer to the flow of steps S111 → S118 → S119 in FIG. 4 described later). That is, as a result of collation from the top in accordance with the priority order, the lowest priority order information that matches the withdrawal information and the stored information is the lowest priority order that matches any of the read information and the stored information. When the priority is higher than the rank information, it is determined whether or not the conveyance target product 50 on the conveyance line 10 is to be retreated to the first or second retreat lines 12 and 14. In other words, when the number of rank information that matches between the saved information and the stored information from the top of the priority order is smaller than the number of rank information that matches the top order of the priority between the read information and the stored information. In addition, it is determined whether or not the product to be transported 50 of the transport line 10 is retracted to the first or second retreat line 12 or 14.

  At this time, the reading information of the first conveyance reading sensor 21 that has read the conveyance target product 50 at the first reading position does not coincide with the stored information at least in the first order information, and is at the second to sixth reading positions. When any of the read information of the second to sixth transport reading sensors 22 to 26 that read a certain transport target product 50 matches the stored information at least in the first rank information (see pattern D in Table 2), It is determined that the product to be transported 50 on the transport line 10 is retracted to the retreat lines 12 and 14 until the product to be transported 50 having identification information matching at least the first rank information with the stored information arrives at the first reading position. (The transfer source line is the transfer line 10 and the transfer destination line is the first or second evacuation line 12, 14), and the lines 10, 12, 14, 16 and the rotation according to the conditions described in paragraph [0027] It is set to operate controls each of the transport device 18 (see the flow of steps S202 → S205 in FIG. 5 to be described later).

  In other words, by providing the conveyance line 10 with a plurality of reading positions where the identification information given to the conveyance target product 50 can be read, the identification information of the conveyance target product 50 at the first reading position in the conveyance line 10 is obtained. Even if the stored information and the first order information do not match, the identification information of the transport target product 50 at the second to sixth reading positions in the transport line 10 matches the stored information at least with the first order information. In this case, the transport target product 50 on the transport line 10 is retracted to the first or second retreat lines 12 and 14 so that the transport target product 50 having the same first rank information is preferentially sent to the unload line 16. As described above, it is possible to accurately and finely sort the products to be transported 50 as described above.

  Similarly, the reading information of the first conveyance reading sensor 21 that has read the conveyance target product 50 at the first reading position matches only the storage information and the first rank information, and is at the second to sixth reading positions. When any of the reading information of the second to sixth transport reading sensors 22 to 26 that read the transport target product 50 is identical in both the stored information and the first and second order information (see pattern E in Table 2). Until the transport target product 50 having the identification information in which the stored information and the first and second order information coincide with each other reaches the first reading position, the transport target product 50 of the transport line 10 is moved to the retreat lines 12 and 14. Decided to evacuate (the conveyance source line is the conveyance line 10 and the conveyance destination line is the first or second evacuation line 12, 14), and the lines 10, 12, 14, 16 and rotary carrying It is set to operate controls respective device 18 (see the flow of steps S202 → S205 in FIG. 5 to be described later).

  Therefore, by providing the conveyance line 10 with a plurality of reading positions where the identification information given to the conveyance target product 50 can be read, the identification information of the conveyance target product 50 at the first reading position in the conveyance line 10 can be obtained. Even if only the stored information and the first order information match, the identification information of the transport target product 50 at the second to sixth reading positions in the transport line 10 is the stored information and the first and second orders. When the pieces of information match each other, the transfer target product 50 on the transfer line 10 is retreated to the first or second retreat lines 12 and 14 so that the transfer target product 50 having the same first rank information is preferentially stored. It can be sent out to the carry-out line 16, and the conveyance target product 50 can be accurately and finely sorted as described above.

  When determining whether or not the product to be transported 50 on the transport line 10 is to be retracted to the retreat lines 12 and 14, the read information read by the first transport reading sensor 21 matches only the stored information and the first rank information. When the read information read by the second to sixth transport reading sensors 22 to 26 does not coincide with the stored information at least in the first order information (see pattern F in Table 2), the control means 36 10 conveyance target products 50 are decided to be conveyed to the carry-out line 16 (the conveyance source line is the conveyance line 10 and the conveyance destination line is the carry-out line 16), and each of the lines 10, 10 according to the conditions described in paragraph [0027] 12, 14, 16 and the rotary transfer device 18 are set to control the operation (see the flow of steps S 202 → S 203 in FIG. 5 described later). As described above, when the conveyance target product 50 having the first order information coincides with the conveyance target product 50 conveyed to the shipping process by the previous unloading line 16, the matching conveyance target product 50 is selected. Since it can be transported by the unloading line 16, it is possible to accurately sort the transport target product 50. Since a plurality of reading positions are provided on the transport line 10 and the identification information of the plurality of transport target products 50 is collated with each of the stored information, the first rank information of the read information is the first rank information of the stored information. If the first rank information of the read information of the conveyance target product 50 that matches and is in the second to sixth reading positions does not match the first rank information of the stored information, the conveyance target product in the first reading position It can be quickly recognized that there is no need to retreat 50 to the retreat lines 12 and 14.

  Similarly, when determining whether or not the product to be transported 50 of the transport line 10 is retracted to the retreat lines 12 and 14, the read information read by the first transport reading sensor 21 is stored information and first and second order information. (See pattern G in Table 2), the control unit 36 determines to transport the transport target product 50 of the transport line 10 to the unload line 16 (the transport source line is the transport line 10). The transport destination line is set to carry out operation control of each of the lines 10, 12, 14, 16 and the rotary transport device 18 in accordance with the conditions described in the paragraph number [0027]. (Refer to the flow of steps S202 → S203 in FIG. 5). As described above, when the transport target product 50 transported to the shipping process by the previous unloading line 16 and the transport target product 50 having the first and second rank information coincide with each other at the first reading position, the matching transport target. Since the product 50 can be transported by the unloading line 16, the transport target product 50 can be accurately sorted. In addition, since a plurality of reading positions are provided on the conveyance line 10 and the identification information of the plurality of conveyance target products 50 is collated with each of the stored information, the first rank information of the read information is the first and second of the stored information. If it matches the rank information, it can be quickly recognized that there is no need to retreat the conveyance target product 50 at the first reading position to the retreat lines 12 and 14.

(When the product to be transported is not evacuated to the first and second evacuation lines)
When the transport target product 50 is not retracted in the first and second retreat lines 12 and 14, the control unit 36 determines whether or not the transport target product 50 in the transport line 10 is retreated to the retreat lines 12 and 14. (See the flow of steps S109 to S117 in FIG. 4 described later). Here, as a result of the collation by the determination means 40, if none of the read information matches at least the first rank information with the stored information (see pattern 7 in Table 3), the product to be transported 50 on the transport line 10 Are transferred to the unloading line 16 (the transfer source line is the transfer line 10 and the transfer destination line is the unload line 16), and according to the conditions described in paragraph [0027], the lines 10, 12, 14, 16 and It is set to control the operation of each of the rotary conveying devices 18 (see the flow of steps S117 → S106 in FIG. 4 described later). That is, similarly to the above, there is no transport target product 50 having the same shipping destination (first rank information) as the transport target product 50 transported to the shipping process by the carry-out line 16 last time, and the transport target product 50 does not exist. 50 cannot be grouped for each shipping destination, and the products 50 to be transported on the transport line 10 are transported to the unload line 16 as they are without being retracted to the retreat lines 12 and 14.

  Further, as a result of the collation by the determination means 40, if any of the read information matches at least the first rank information with the stored information (see patterns 8 to 11 in Table 3), It is determined whether or not the product to be transported 50 is retracted to the retreat lines 12 and 14 (the transport source line is the transport line 10 and the transport destination line is the first or second retreat line 12 and 14), and paragraph number [0027] Is set so as to control the operation of each of the lines 10, 12, 14, 16 and the rotary transfer device 18 (see the flow of steps S117 → S119 in FIG. 4 described later).

  In this case, based on the same control as the paragraph numbers [0042] to [0047] described above, the transport source line and the transport destination line of the transport target product 50 are determined. Specifically, the reading information of the first conveyance reading sensor 21 that has read the conveyance target product 50 at the first reading position does not coincide with the stored information at least in the first order information, and the second to sixth readings. When any of the reading information of the second to sixth transport reading sensors 22 to 26 that read the transport target product 50 at the position matches at least the first order information with the stored information (see pattern 8 in Table 3). The transport target product 50 on the transport line 10 is retracted to the retreat lines 12 and 14 until the transport target product 50 having identification information whose at least first order information matches the stored information arrives at the first reading position. (The transport source line is the transport line 10 and the transport destination line is the first or second evacuation line 12, 14), and according to the conditions described in paragraph [0027], the lines 10, 12, 14, 16 and It is set to operate control respectively of formula conveying device 18 (see the flow of steps S202 → S205 in FIG. 5 to be described later).

  Similarly, the reading information of the first conveyance reading sensor 21 that has read the conveyance target product 50 at the first reading position matches only the storage information and the first rank information, and is at the second to sixth reading positions. When any of the reading information of the second to sixth conveyance reading sensors 22 to 26 that read the conveyance target product 50 is coincident between the stored information and the first and second order information (see pattern 9 in Table 3). Until the transport target product 50 having the identification information in which the stored information and the first and second order information coincide with each other reaches the first reading position, the transport target product 50 of the transport line 10 is moved to the retreat lines 12 and 14. Decided to evacuate (the conveyance source line is the conveyance line 10 and the conveyance destination line is the first or second evacuation line 12, 14), and the lines 10, 12, 14, 16 and rotary carrying It is set to operate controls respective device 18 (see the flow of steps S202 → S205 in FIG. 5 to be described later).

  That is, by providing a plurality of reading positions that can read the identification information given to the conveyance target product 50 in the conveyance line 10, in other words, the identification information of the conveyance target product 50 at the first reading position and Compared with the number of rank information that matches the storage information from the top of the priority order, the number of rank information that matches the second to sixth reading positions and the storage information from the top of the priority order is large. Evacuates the conveyance target product 50 at the first reading position of the conveyance line 10 to the first or second evacuation line 12 or 14, and adds identification information having a lot of rank information matching the stored information. The conveyance target product 50 can be preferentially sent to the carry-out line 16, and the conveyance target product 50 can be accurately and finely sorted.

Further, when determining whether or not the product to be transported 50 on the transport line 10 is retracted to the retreat lines 12 and 14, the first rank information of the read information read by the first transport reading sensor 21 is the stored information and the first rank. When the information only matches and the reading information of the conveyance target product 50 at the second to sixth reading positions does not match the stored information at least in the first order information (see pattern 10 in Table 3), the control means 36 decides to convey the product 50 to be conveyed on the conveyance line 10 to the carry-out line 16 (the conveyance source line is the conveyance line 10 and the conveyance destination line is the carry-out line 16), according to the conditions described in paragraph [0027]. Each of the lines 10, 12, 14, 16 and the rotary transfer device 18 is set to control the operation (see the flow of steps S202 → S203 in FIG. 5 described later). Similarly, when determining whether or not the product to be transported 50 on the transport line 10 is retracted to the retreat lines 12 and 14, the first rank information of the read information read by the first transport reading sensor 21 is stored information and first information. When the second order information matches the second order information (see pattern 11 in Table 3 ), the control unit 36 determines to transport the transport target product 50 of the transport line 10 to the unload line 16 (transport source line). Is the transfer line 10, the transfer destination line is the discharge line 16), and the lines 10, 12, 14, 16 and the rotary transfer device 18 are set to be controlled in accordance with the conditions described in paragraph [0027]. (See the flow of steps S202 → S203 in FIG. 5 described later).

  That is, by providing a plurality of reading positions that can read the identification information given to the conveyance target product 50 in the conveyance line 10, in other words, the identification information of the conveyance target product 50 at the first reading position and Compared with the number of rank information that matches the stored information from the top of the priority order, the number of rank information that matches the second to sixth reading positions and the storage information from the top of the priority order is small. Can preferentially send the transport target product 50 at the first reading position whose order information is more consistent with the transport target product 50 transported to the shipping process by the previous transport line 16 to the transport line 16; Accurate and fine sorting of the conveyance target product 50 is possible.

  In the state where the product to be transported 50 is not transported to the shipping process on the unloading line 16 (that is, the state in which the storage unit 38 does not have stored information), such as when the production line starts, the control unit 36 When the product to be transported 50 is retracted to either the first or second retreat line 12, 14, the transport target product 50 of the retreat line 12, 14 is determined to be transported to the unload line 16 (conveying source If the line is the first or second evacuation line 12, 14, the conveyance destination line is the carry-out line 16), and the conveyance target product 50 is not evacuated to the first and second evacuation lines 12, 14, the conveyance line 10 It is determined that the product to be transported 50 is transported to the carry-out line 16 (the transport source line is the transport line 10 and the transport destination line is the carry-out line 16), and according to the conditions described in paragraph [0027], the lines 10, 2,14,16 and is set to operate controls respective rotary transport device 18 (see the flow of steps S102 → S103 in FIG. 4 to be described later). That is, when the transport target product 50 is in the first or second retreat line 12 or 14 in a state where the transport target product 50 is not transported toward the shipping process by the carry-out line 16, the retreat line 12 or 14. The transport target product 50 is controlled so as to be transported to the unloading line 16 preferentially and the transport target product 50 is prevented from stagnation in the evacuation lines 12 and 14.

  Thus, the identification information given to the conveyance target product 50 is the first and sixth conveyance reading sensors 21 to 26 provided on the conveyance line 10 and the first and second conveyance lines 12 and 14 provided on the first and second retraction lines 12 and 14. 2 The reading operation is performed by each of the retraction reading sensors 31 and 32 and the unloading reading sensor 34 provided in the unloading line 16, so that the sorting work of the conveyance target product 50 can be automatically performed based on the identification information. That is, compared with the case where sorting work is performed manually, there is an advantage that work efficiency can be greatly improved and work errors can be reduced.

(Regarding the control mode of each line and rotary conveyor)
Next, an example of the control mode of each of the lines 10, 12, 14, 16 and the rotary transfer device 18 will be schematically described with reference to FIGS. 4 to 7.

  When various inspection operations such as operation check in the work area are completed, the product to be transported 50 in the work area is transported via the transport line 10, and the product to be transported 50 is subjected to each process shown in FIGS. Based on the first retreat line 12, the second retreat line 14, or the carry-out line 16. In the carry-out process shown in FIG. 4, first, the identification information of the conveyance target product 50 that has arrived at the first to sixth reading positions of the conveyance line 10 is sequentially read by the corresponding first to sixth conveyance reading sensors 21 to 26 (steps). S101). In step S102, it is determined whether the storage unit 38 stores identification information. At this time, if the storage unit 38 stores the identification information, the process proceeds to step S108, and if the storage unit 38 does not store the identification information, the process proceeds to step S103. That is, when the product 50 to be transported has already been transported to the shipping process via the carry-out line 16, the process proceeds to step S108, while the product 50 to be transported still remains via the carry-out line 16 as in the initial operation of the production line. If it has not been transported to the shipping process, the process proceeds to step S103.

  In step S103, it is determined whether or not the product to be transported 50 is retracted to the first or second retreat line 12 or 14. Here, when the transport target product 50 is retracted to any of the retreat lines 12 and 14, the retreat lines 12 and 14 on which the transport target product 50 is waiting are stored in the storage unit 38 as transport source line information. At the same time, after the carry-out line 16 is stored in the storage means 38 as the transfer destination line information (steps S104 and S105), the process proceeds to step S116 and a carry-out execution process (see FIG. 7) described later is performed. In addition, when the conveyance target product 50 is evacuated to each of the first and second evacuation lines 12, 14, the first evacuation line 12 is set to be stored as conveyance source line information. On the other hand, when it is determined in step S103 that the conveyance target product 50 is not retracted in any of the retreat lines 12 and 14, the transport line 10 is stored in the storage unit 38 as the transport source line information and the unloading line. 16 is stored in the storage means 38 as transport destination line information (steps S106 and S107), and then the process proceeds to step S116 and a carry-out execution process (see FIG. 7) is performed. That is, at the beginning of the operation of the production line, the transport target product 50 retracted in the first and second retreat lines 12 and 14 is transported to the transport line 16 in preference to the transport target product 50 in the transport line 10. Thus, the conveyance target product 50 is prevented from staying in the retreat lines 12 and 14.

  Further, when the process proceeds from step S102 to step S108, the storage information stored in the storage unit 38 is acquired, and then whether or not there is a product 50 to be transported in the first or second evacuation line 12, 14 is determined. Determination is made (step S109). That is, when the conveyance target product 50 is retracted to the first or second retraction line 12 or 14 (at least one of the first and second retraction reading sensors 31 and 32 reads the identification information of the conveyance target product 50). The identification information of the evacuated conveyance target product 50 is read by the first and second evacuation reading sensors 31 and 32 (step S110), and the read evacuation information and the stored information are collated. It is determined whether the first rank information matches (step S111). Here, if the first rank information matches between the save information and the storage information, whether or not the second rank information matches between the save information for the save information that matches the first rank information. Is further determined (step S112). If there is evacuation information that also matches the second rank information with the stored information, each of the first and second rank information of the stored information is stored in the storage means 38 as specific information (step S113). . Then, the evacuation lines 12 and 14 corresponding to the evacuation reading sensors 31 and 32 that read the evacuation information that matches the specific information are stored in the storage means 38 as the conveyance source line information, and the carry-out line 16 as the conveyance destination line information. The data is stored in the storage means 38 (steps S114 and S115), and a carry-out execution process (see FIG. 7) described later is performed (step S116).

  That is, as a result of the collation by the determination means 40, all the rank information of the evacuation information read by the first or second evacuation reading sensor 31, 32 is stored in the respective ranks of the storage information stored in the storage means 38. If the information matches the information, the conveyance target product 50 having the matching identification information is sent from the evacuation lines 12 and 14 to the carry-out line 16. In this way, when the same type of transport target product 50 having the same shipping destination and specifications as the transport target product 50 transported to the shipping process by the unloading line 16 is present in the retreat line 12, the retreat line 12. , 14 can be transported preferentially and reliably to the unloading line 16, so that the transport target product 50 can be prevented from stagnation in the evacuation lines 12, 14.

  In step S111, if there is no evacuation information that matches the stored information and the first rank information, the process proceeds to step S118, and the read information read by the first to sixth transport reading sensors 21 to 26 is added to the read information. It is determined whether there is a match between the stored information and the first rank information. If none of the read information matches the stored information and the first rank information, the process proceeds to step S104, and the evacuation lines 12 and 14 on which the transfer target product 50 is waiting are stored as transfer source line information. And the unloading line 16 is stored in the storage means 38 as the transfer destination line information (step S105), and unloading execution processing (see FIG. 7) described later is performed (step S116).

  That is, the control unit 36 determines that the save line 12 and the first rank information of the read information do not match the first rank information of the storage information as a result of the collation in the determination unit 40. , 14 are delivered to the carry-out line 16. In other words, as described above, the products to be transported 50 are required to be grouped for each shipping destination (that is, the first rank information), but the products to be transported previously transported to the shipping process by the unloading line 16. When there is no transport target product 50 having the same shipping destination (first order information) as that of the transport line 10 and the retreat lines 12 and 14, the transport target product 50 of the retreat lines 12 and 14 is given priority. Then, the product 50 is conveyed to the carry-out line 16 and the conveyance target product 50 is prevented from staying in the retreat lines 12 and 14.

  If any of the first rank information of the read information read by the first to sixth transport reading sensors 21 to 26 matches the first rank information of the stored information in step S118, the process proceeds to step S119. move on. In step S119, for the read information that matches the stored information and the first rank information, it is further determined whether the stored information and the second rank information also match. If there is read information that also matches the second rank information with the stored information, each of the first and second rank information of the stored information is stored as specific information in the storage means 38 (step S120). If there is no read information that also matches the second rank information, only the first rank information of the stored information is stored as the specific information in the storage means 38 (step S121), and later-described save determination process (see FIG. 5). Is performed (step S125).

  Further, in step S112, when there is no match between the storage information and the second rank information for the saved information that matches the stored information and the first rank information, the process proceeds to step S122. In step S122, it is determined whether or not there is a match between the stored information and the first rank information and the second rank information in each read information. At this time, if none of the read information matches in both the first rank information and the second rank information of the stored information, the process proceeds to step S123 and the first rank information of the stored information is stored in the storage means 38 as the specific information. Then, the process proceeds to step S114, and the evacuation lines 12, 14 corresponding to the evacuation reading sensors 31, 32 reading the evacuation information that matches the specific information are stored in the storage means 38 as the conveyance source line information, and the carry-out line 16 is stored in the storage means 38 as transport destination line information (steps S115 and S116), and a carry-out execution process (see FIG. 7) described later is performed (step S116).

  In step S122, if there is information that matches the first rank information and the second rank information of the stored information among the read information read by the first to sixth transport reading sensors 21 to 26, Proceeding to step S124, each of the first and second rank information of the stored information is stored as specific information in the storage means 38, and a later-described save determination process (see FIG. 5) is performed (step S125).

  In the save determination process, as shown in FIG. 5, first, the specific information stored in the storage unit 38 is acquired (step S201). In step S202, it is determined whether the reading information of the first conveyance reading sensor 21 (first reading position) in the conveyance line 10 matches the specific information stored in the storage unit 38. The process proceeds to step S203, and if they do not match, the process proceeds to step S205. That is, the process proceeds from step S120 or step S124 in the unloading process of FIG. 4 to the evacuation determination process, and the first and second rank information of the identification information of the conveyance target product 50 at the first reading position is the rank of correspondence of the stored information. If the information matches the information, the process proceeds to step S203, the process proceeds from step S121 in the unloading process of FIG. 4 to the saving determination process, and only the first rank information of the identification information of the conveyance target product 50 at the first reading position is stored information. If the corresponding rank information matches, the process proceeds to step S203. In step S203, the transport line 10 is stored in the storage unit 38 as transport source line information, and the carry-out line 16 is stored in the storage unit 38 as transport destination line information (step S204), and the evacuation determination process ends. In other words, when a conveyance target product 50 having at least the same first order information as the conveyance target product 50 conveyed to the previous shipping process by the carry-out line 16 is in the first reading position, the conveyance target product 50 is carried out. It can be conveyed to the line 16.

  When the process proceeds from step S202 to step S205, the first evacuation / reading sensor 31 reads the identification information of the product 50 to be conveyed on the first evacuation line 12, and the first evacuation / reading sensor 31 performs the first evacuation based on the reading result. It is determined whether or not there is an “empty” line 12 in which the product to be transported 50 can be evacuated (step S206). That is, when the first retraction reading sensor 31 has not read retraction information, the first retreat line 12 has “empty” in which the conveyance target product 50 can be retreated, and the process advances to step S207 to convey the conveyance line 10. The original line information is stored in the storage unit 38 and the first evacuation line 12 is stored in the storage unit 38 as the transfer destination line information (step S208), and then the evacuation execution process (see FIG. 6) is performed (step S209). ). As described above, when the conveyance target product 50 at the first reading position is retracted, if the first retraction line 12 is “empty”, the conveyance target product 50 is retracted to the first retraction line 12.

  On the other hand, when the first evacuation reading sensor 31 is reading the evacuation information, there is no “empty” in the first evacuation line 12 in which the conveyance target product 50 can be evacuated. The sensor 32 reads the identification information of the conveyance target product 50 in the second evacuation line 14, and “vacant” can evacuate the conveyance target product 50 to the second evacuation line 14 based on the reading result of the second evacuation reading sensor 32. It is determined whether or not there is (step S211). That is, when the second retraction reading sensor 32 has not read retraction information, the second retreat line 14 has “empty” that can retreat the conveyance target product 50, and the process proceeds to step S 212 to convey the conveyance line 10. The original line information is stored in the storage unit 38, and the second save line 14 is stored in the storage unit 38 as the transfer destination line information (step S213), and then the save execution process (see FIG. 6) is performed (step S209). ). As described above, when the conveyance target product 50 at the first reading position is retracted, if there is no “empty” in the first retracting line 12 and “empty” in the second retracting line 14, the second The conveyance target product 50 is retracted to the retreat line 14.

  In step S211, if the second retraction reading sensor 32 is reading retraction information, there is no “empty” in the second retreat line 14 that can retreat the conveyance target product 50, and the process proceeds to step S214 to notify. The means 42 is activated. That is, since the product 50 to be transported has already been retracted to each of the first and second retreat lines 12 and 14 and the product 50 to be transported cannot be retracted, the operator is notified of the abnormality. Yes.

  In step S209, the save execution process shown in FIG. 6 is performed. In the evacuation execution process, based on the conveyance source line information stored in the storage means 38 in step S207 or step S212 in FIG. 5, the rotary conveyance device 18 is set at the receiving position corresponding to the conveyance line 10 as the conveyance source line. Rotate (step S301), and move the conveyance target product 50 waiting at the first reading position of the conveyance line 10 to the rotary conveyance device 18 (step S302). Next, based on the transport destination line information stored in the storage means 38 in step S208 or step S213 in FIG. 5, the rotary transport device 18 corresponds to the first or second retreat line 12, 14 as the transport destination line. (Step S303), and moves to the first or second evacuation line 12, 14 as the conveyance destination line on which the conveyance target product 50 received in step S302 should be evacuated (step S303). Step S304). Thereafter, the transfer source line information, the transfer destination line information, and the specific information stored in the storage unit 38 are deleted (steps S305 and S306), and the save execution process ends.

  Next, the carry-out execution process according to step S116 in FIG. 4 will be described. In the carry-out execution process, as shown in FIG. 7, it is first determined whether or not the storage unit 38 stores the transfer source line information (step S401). That is, when the transfer source line information has been deleted in step S305 of the save execution process (see FIG. 6), the carry-out execution process ends. When the storage unit 38 stores the transport source line information, based on the transport source line information, the receiving position or the evacuation line 12 corresponding to the transport line 10 as the transport source line based on the rotary transport device 18. , 14 (step S402). That is, when the process proceeds from step S107 in the unloading process or step S204 in the evacuation determination process to the unloading execution process, it corresponds to the transport line 10 stored as the transport source line information in the storage unit 38 in step S106 or step S203. When the rotary conveying device 18 is rotated to the receiving position and the process proceeds from step S105 or step S115 in the unloading process to the unloading execution process, the storage unit 38 stores the first source line information stored in step S104 or step S114. The rotary transfer device 18 is rotated to the delivery position corresponding to the first or second retreat line 12 or 14.

  Then, the transport target product 50 waiting at the first reading position of the transport line 10 as the transport source line, or the transport target product 50 retracted to the first or second retreat position of the retreat lines 12 and 14, It moves to the rotary transfer device 18 (step S403). Next, based on the transport destination line information stored in the storage means 38, the rotary transport device 18 is rotated to the delivery position corresponding to the carry-out line 16 as the transport destination line (step S404), and the rotary transport device. The product 50 to be transported received by 18 is moved to the carry-out line 16 as a transport destination line (step S405). Thereafter, the transfer source line information, the transfer destination line information, and the specific information stored in the storage unit 38 are erased (steps S406 and S407). When the carry-out reading sensor 34 reads the identification information of the conveyance target product 50 received by the carry-out line 16, the storage information in the storage means 38 is updated to the identification information read by the carry-out read sensor 34, and then the carry-out line. 16 is operated to convey the product 50 to be shipped toward the shipping process, and the unloading execution process ends (steps S408 and S409).

(Effects of Example)
Next, the conveyance of the conveyance target product 50 will be described with reference to specific examples shown in FIGS. Here, in the specific examples shown in FIGS. 8 to 24, the product 50 to be transported of the specification A (second order information) to be shipped to a predetermined number of halls (first order information) is transported by the transport line 10. Thereafter, the product 50 of the specification B (second order information) to be shipped to a predetermined number of upper halls (first order information) is transported on the transport line 10, and thereafter, a predetermined number of second holes (first order information). In the case of transporting the transport target product 50 of the specification A (second rank information) to be transported toward the first rank information) on the transport line 10, the transport target product 50 transported on the transport line 10 is of a type (first This shows a state in which products 50 to be conveyed having different order information and second order information) are mixed. That is, the storage means 38 stores identification information [first rank information (layer A hall) and second rank information (spec A)] of the object 50 to be transported last time by the unloading line 16 to the shipping process. Yes. Further, the product to be transported 50 is not retracted in any of the first and second retreat lines 12 and 14. Further, the rotary transport device 18 is held at the delivery position by the previous transport of the product to be transported 50 to the shipping process. In order to facilitate understanding of the transport state of the transport target product 50, in FIGS. 8 to 24, “top”, “second” and second rank information indicating the first order information are shown for each transport target product 50. “A” and “B” are attached.

  When the conveyance target product 50 conveyed by the conveyance line 10 reaches the first reading position (see FIG. 8), the conveyance line 10 is stopped and the conveyance read by the first to sixth conveyance reading sensors 21 to 26 is performed. The reading information (first and second order information) of the target product 50 is collated with the storage information (first and second order information) stored in the storage unit 38 and the determination unit 40. At this time, the reading information read by the first transport reading sensor 21 and the storage information stored in the storage means 38 are both “first hall information” and second order information “spec”. A ”matches. Therefore, the conveyance line 10 is operated to move the conveyance target product 50 waiting at the first reading position to the rotary conveyance device 18 (see FIG. 9). Then, the transport target product 50 received by the rotary transport device 18 is sent to the transport line 16 as it is (see FIG. 10), and the first transport reading sensor 21 identifies the next transport target product 50 (first information). When the rank information (the former hall) and the second rank information (spec B)] are read, the conveyance line 10 is stopped. Then, the storage information of the storage means 32 is updated to the identification information newly read by the carry-out reading sensor 34 provided on the carry-out line 16 [first rank information (class A hall) and second rank information (spec A)]. To do.

  Next, each of the reading information (first and second order information) of the conveyance target product 50 newly read by the first to sixth conveyance reading sensors 21 to 26 is stored in the storage information (first and second). The second order information) and the determination means 40 collate. At this time, the second order information does not match the reading information read by the first transport reading sensor 21 and the storage information stored in the storage unit 38. However, the reading information read by the second transport reading sensor 22 and the like is the same as the storage information stored in the storage means 38 as the first rank information is “Class Hall” and the second rank information is “Spec A”. To do. Accordingly, the conveyance line 10 is operated to move the conveyance target product 50 waiting at the first reading position to the rotary conveyance device 18 (see FIG. 11), and then the rotary conveyance device 18 is moved to the first delivery position. The product to be conveyed 50 that has been rotated and received is retreated to the first retreat line 12 (see FIG. 12). When the first conveyance reading sensor 21 reads the identification information [first rank information (Hole) and second rank information (Spec A)] of the next conveyance object 50, the conveyance line 10 is stopped. The next conveyance target product 50 is put on standby at the first reading position.

  When the conveyance target product 50 is retreated to the first retreat line 12, the determination unit 40 retrieves retraction information (first and second order information) read by the first retraction reading sensor 31 provided on the first retraction line 12. Is compared with the stored information (first and second order information) of the storage means 32. At this time, the evacuation information [first rank information (Hole) and second rank information (Spec B)] and storage information [first rank information (Hole) and second rank information (Spec A)] are Since the two rank information does not match, the determination unit 40 obtains the read information (first and second rank information) of the conveyance target product 50 newly read by the first to sixth conveyance reading sensors 21 to 26, respectively. The stored information (first and second order information) in the storage means 32 is collated again.

  Here, the reading information [first rank information (Hole) and second rank information (Spec A)] read by the first transport reading sensor 21 and the storage information [first rank information stored in the storage unit 38]. The information (the first hall) and the second ranking information (spec A)] match each of the first ranking information and the second ranking information. Therefore, the conveyance line 10 is operated while the rotary conveyance device 18 is rotated to the receiving position, and the conveyance target product 50 waiting at the first reading position is moved to the rotary conveyance device 18 (FIG. 13). Then, the transport target product 50 received by the rotary transport device 18 is sent to the unload line 16 as it is (see FIG. 14), and the first transport reading sensor 21 identifies the next transport target product 50 (first information). When the rank information (class A hall) and the second rank information (spec A) are read, the conveyance line 10 is stopped. Then, the storage information of the storage means 32 is updated to the identification information newly read by the carry-out reading sensor 34 provided on the carry-out line 16 [first rank information (class A hall) and second rank information (spec A)]. To do.

  Note that the identification information of the conveyance target product 50 waiting at the first reading position is that the first rank information is “Class A Hall” and the second rank information is “Spec A”. The specific operations of 14, 16 and the rotary transfer device 18 are as described in the paragraph numbers [0064] and [0065] described above. That is, the transport target product 50 at the first reading position is transported to the carry-out line 16, and a new transport target product 50 [first rank information (second hole) and second rank information (spec A) is transferred to the first read position. ] Has arrived, and the storage information of the storage means 38 is updated to the identification information newly read by the carry-out reading sensor 34 (first rank information (Class Hall) and second rank information (Spec A)) (see FIG. 15 and FIG. 16).

  When the product 50 to be transported is transported on the carry-out line 16, the determination unit 40 performs a verification again. At this time, the evacuation information [first order information (Hole) and second order information (Spec B)] read by the first evacuation / reading sensor 31 is stored in the storage unit 38 [first order information as described above]. The information (former hall) and the second order information (spec A)] do not coincide with each other in the second order information. Therefore, the reading information of the transport target product 50 newly read by the first to sixth transport reading sensors 21 to 26. Each of the (first and second order information) is collated with the stored information (first and second order information) in the storage means 32.

  Here, the read information [first rank information (second hole) and second rank information (spec A)] read by the first transport reading sensor 21 is stored information [first rank information] stored in the storage unit 38. The (first hall information) and the second ranking information (spec A)] do not match the first ranking information and the second ranking information. However, the reading information read by the second transport reading sensor 22 and the like is the same as the storage information stored in the storage means 38 as the first rank information is “Class Hall” and the second rank information is “Spec A”. To do. Further, although the transport target product 50 is retracted to the first retreat line 12, the transport target product 50 is not retracted to the second retreat line 14. Therefore, the conveyance target product 50 waiting at the first reading position by operating the conveyance line 10 is moved to the rotary conveyance device 18 (see FIG. 17), and then the rotary conveyance device 18 is moved to the second delivery position. The product 50 to be conveyed that has been rotated is retreated to the second retreat line 14 (see FIG. 18). When the first conveyance reading sensor 21 reads the identification information [first rank information (Hole) and second rank information (Spec A)] of the next conveyance object 50, the conveyance line 10 is stopped. The next conveyance target product 50 is put on standby at the first reading position.

  Then, under the same conditions as described above, the conveyance target product 50 to which the identification information of the first rank information is the upper hall and the second rank information is the spec A is sequentially transferred from the conveyance line 10 to the carry-out line 16. Be transported. After that, a description will be given of a case where the conveyance target product 50 to which the identification information of the first rank information is “Class Hall” and the second rank information is “Spec B” is conveyed to the first reading position by the conveyance line 10. (See FIG. 19). As described above, as a result of collation by the determination means 40, the retraction information read by the first and second retraction reading sensors 31, 32 and the reading information read by the first to sixth transport reading sensors 21-26. None of the storage information stored in the storage means 38 matches the first and second ranking information. However, the retraction information read by the first retraction reading sensor 31 and the reading information read by the first to sixth transport reading sensors 21 to 26 include the storage information stored in the storage unit 38 and the first order information. Matches as “Hole Hall”. In this case, the transport target product 50 retracted to the first retreat line 12 is transported to the carry-out line 16 in preference to the transport target product 50 of the transport line 10, so that the rotary transport device 18 is used. The product 50 to be conveyed on the first retreat line 12 is moved to the rotary transfer device 18 by rotating to the first delivery position (see FIG. 20), and then the rotary transfer device 18 is sent to the delivery position and received. The product 50 to be conveyed is sent to the carry-out line 16 (see FIG. 21). Then, the stored information of the storage means 32 is updated to the identification information newly read by the carry-out reading sensor 34 provided on the carry-out line 16 [first rank information (Hole) and second rank information (Spec B)]. Is done.

  When the object 50 to be conveyed on the first evacuation line 12 is conveyed on the carry-out line 16, the determination unit 40 performs verification again. At this time, the evacuation information [first rank information (second hall) and second rank information (spec A)] read by the second evacuation / reading sensor 32 is stored in the storage information [first rank information (first hall)). And second order information (spec B)] and the first and second order information do not match, so the reading information (50) of the conveyance target product 50 newly read by the first to sixth conveyance reading sensors 21 to 26 ( Each of the first and second rank information) is collated with the stored information (first and second rank information) in the storage means 32.

  Here, the read information [first rank information (the hall) and second rank information (spec B)] read by the first conveyance reading sensor 21 is the storage information [first rank information stored in the storage unit 38]. The information (the first hall) and the second rank information (spec B)] and the first rank information and the second rank information coincide with each other. Accordingly, the transport line 10 is operated to move the transport target product 50 waiting at the first reading position to the rotary transport device 18 (see FIG. 22), and the transport target received by the rotary transport device 18. The product 50 is sent as it is to the carry-out line 16 (see FIG. 23). When the first conveyance reading sensor 21 reads the identification information [first rank information (Hole) and second rank information (Spec B)] of the next conveyance target product 50, the conveyance line 10 is stopped. The next conveyance target product 50 is put on standby at the first reading position.

  Thereafter, the conveyance target product 50 to which the identification information of the first rank information is the instep hall and the second rank information is the spec B is sequentially conveyed from the conveyance line 10 to the carry-out line 16. Then, a description will be given of a case where the conveyance target product 50 to which the identification information of the first rank information is “B Hall” and the second rank information is “Spec A” is conveyed to the first reading position by the conveyance line 10. (See FIG. 24). At this time, similarly to the above, as a result of the collation by the determination means 40, the retraction information read by the second retreat reading sensor 32 and the read information read by the first to sixth transport reading sensors 21 to 26, respectively. Does not match the storage information stored in the storage means 38 with the first rank information. In this case, the transport target product 50 retracted to the second retreat line 14 is transported to the carry-out line 16 in preference to the transport target product 50 of the transport line 10, so that the rotary transport device 18 is Rotate to the second delivery position to move the object 50 to be conveyed on the second evacuation line 14 to the rotary conveyance device 18 (see FIG. 25), and then rotate the rotary conveyance device 18 to the delivery position and receive it. The product 50 to be transported is sent to the carry-out line 16 (see FIG. 26). Then, the storage information of the storage means 32 is updated to the identification information [first rank information (second hall) and second rank information (spec A)] newly read by the carry-out reading sensor 34 provided on the carry-out line 16. Is done.

  Further, when the conveyance target product 50 in the first evacuation line 12 is conveyed on the carry-out line 16, collation is performed again by the determination means 40. At this time, the read information [first rank information (second hole) and second rank information (spec A)] read by the first transport reading sensor 21 is stored in the storage information [first rank information]. Information (second hall) and second rank information (spec A)], and the first rank information and the second rank information coincide with each other. Therefore, similarly to the paragraph numbers [0064] and [0065] described above, the product 50 to be transported in the transport line 10 is sequentially transported to the carry-out line 16.

  As described above, in the specific examples shown in FIGS. 8 to 26, the product to be transported 50 transported to the shipping process by the carry-out line 16 is the transport target whose shipping destination is “Exhibition Hall” based on the first rank information. The product 50 and the product to be transported 50 whose shipping destination is “Otsu Hall” are grouped and transported to the shipping process, and the products to be transported in the group (for example, the shipping destination is “Koh Hall”) are further grouped. Based on the second rank information (“Spec A” or “Spec B”), it becomes possible to finely sort.

[Example of change]
Note that the gaming machine production line according to the present invention is not limited to the example, and various modifications can be made. For example, in the embodiment, the two evacuation lines, the first and second evacuation lines, are provided as the evacuation lines. However, it is possible to provide one or three or more evacuation lines. In the embodiment, the configuration is such that one transport target product can be retracted to the retreat line, but the present invention is not limited to this, and two or more transport target products may be retracted to the retreat line. Here, in a case where a plurality of conveyance target products can be retreated to the retreat line, it is preferable to retreat the same type of conveyance target products to the retreat line. In other words, when different types of products to be transported are retracted to the retreat line, if there is a product to be transported on the front side of the retreat line (position close to the selected transport means), the back side of the retreat line (selected This is because there is a problem that the product to be transported that has been retreated to a position away from the transport means cannot be moved to the unload line. When multiple items to be transported are retracted to the retreat line, the product to be transported can be retreated to the retreat line by reading the identification information given to each product to be transported by the second reading means. It is possible to accurately determine whether or not there is a “vacant”.

  In the embodiment, the configuration in which one rotary transport device is provided as the selective transport unit has been described as an example. However, a plurality of the selective transport units may be provided. For example, as shown in FIG. 27, a plurality of rotary transfer devices 18 may be provided adjacent to each other, and two retreat lines 55 may be provided for each rotary transfer device 18. That is, in the state in which the rotary transport device 18 is rotated to the delivery position, the product to be transported 50 is transported to the rotary transport device 18 on the downstream side (the unloading line 16 side), so that it can be transported to any retreat line 55. The product 50 can be retracted, and the product 50 to be transported retracted to the retreat line 55 at an arbitrary position can be sequentially transported to the downstream side after being delivered to the corresponding rotary transport device 18. The effect of this can be obtained. Furthermore, since a large number of evacuation lines 55 can be installed, it is possible to evacuate more products to be transported 50, and it is possible to reliably perform the sorting operation of the products to be transported 50. In addition, although the example which provided 3 units | sets was shown in FIG. 27, it is not restricted to this. In FIG. 27, the same members as those in the embodiment are denoted by the same reference numerals.

  Further, the arrangement of the transfer line, the evacuation line, and the carry-out line is not limited to the arrangement shown in the embodiment, and can be arranged radially around the selected conveyance means or arranged so as to be positioned up and down. . Moreover, as said 1st conveyance line and 2nd conveyance line, it is not restricted to the roller conveyor type thing shown in an Example, If conventionally the conveyance object goods can be conveyed and conveyance stop, it is well-known conventionally Various conveying means can be employed. In the embodiment, the shipping destination information and the specification information are provided as the identification information given to the products to be transported by the first transport line. However, the present invention is not limited thereto, and arbitrary information may be included. In addition, as long as the number of rank information included in the identification information is 1 or more, any number of rank information can be provided.

  Further, in the embodiment, the rotary conveying means is used as the selective conveying means connected to the conveying line, the evacuation line and the unloading line. However, the present invention is not limited to this, and the selective conveying means can be moved in parallel. It is also possible to do. For example, when each line is arranged apart from the top and bottom, it can be connected to the retreat line and the receiving position where it can be connected to the transport line and receive the object to be transported by using the selective transport means that can move in the vertical direction. Thus, the selective conveying means can be moved to a delivery position where the goods to be conveyed can be delivered, and a delivery position where the goods to be conveyed connected to the carry-out line can be delivered to the carry-out line. Similarly, when each line is spaced apart from each other in the left and right direction, it is possible to use a selective conveying means that can move in the left and right direction, so that it can be connected to the conveying line and can be used as a receiving position and a retreat line that can receive the object to be conveyed. The selected conveying means can be moved to a delivery position where it can be connected to deliver the object to be conveyed, and a delivery position where it can be connected to the carry-out line and sent to the carry-out line. The same effect as the example can be obtained. In addition, as shown in the embodiment, by using a rotary conveying means as the selective conveying means, the receiving position, the delivery position, and the sending position are compared with the case where the conveying means that moves up and down or moves in the left-right direction is used. There is an advantage that the selective conveying means can be efficiently moved to each of the above.

  In the embodiment, a plurality of reading positions (six positions in the embodiment) are set on the transport line, but the number of reading positions can be arbitrarily determined. When the reading position is one place, the identification information read by the second reading means of the save line matches the identification information stored in the storage means as a result of collation by the determination means. And when the identification information read by the first reading means of the conveyance line matches the identification information stored in the storage means, it is determined to send the conveyance target product of the conveyance line to the carry-out line, If none of the identification information read by the first and second reading means coincides with the identification information stored in the storage means as a result of the collation by the judging means, the product to be conveyed on the evacuation line is transferred to the carry-out line. What is necessary is just to set so that it may decide to send. The identification information read by the first reading unit does not match the identification information stored in the storage unit as a result of the collation by the determination unit, and the conveyance target product can be retreated to the retreat line. In addition, the control unit may determine to retract the product to be transported on the transport line to the retreat line. That is, when the product to be transported on the transport line is of a different type from the product to be transported on the previous unloading line, the product to be transported on the transport line can be temporarily retracted to the retreat line.

  The control mode of each line and the selected transport means is not limited to that of the embodiment, and the identification information given to the product to be transported is composed of a plurality of rank information having different priorities. 2 When the rank information of the identification information read by the reading means and the corresponding rank information in the identification information stored in the storage means are sequentially collated from the top according to the priority order, and there is rank information that does not match, The determination means is set so as to collate the rank information of each identification information read by the first reading means with the corresponding rank information in the identification information stored in the storage means, and the identification information read by the second reading means And the identification information stored in the storage means, the priority order of the order information that matches the identification information read by the first reading means and the identification information stored in the storage means. Or the priority of the rank information that matches the identification information read by the second reading means and the identification information stored in the storage means is the same as the identification information read by the first reading means. In the case where the order is lower than the priority order of the order information that matches the identification information stored in the storage means, it is decided to transport the product to be transported in the evacuation line to the carry-out line, and the identification read by the second reading means The lowest priority order in which the lowest order information matching the information and the identification information stored in the storage means matches the identification information read by the first reading means and the identification information stored in the storage means If the priority is higher than the information, it may be determined whether or not the product to be transported on the transport line is to be retreated to the retreat line.

  In this way, in the transport target product on the transport line and the transport target product on the evacuation line, the transport target product that matches the transport target product transported last time on the unload line with higher priority information is sent to the unload line. Thus, as in the embodiment, a finer sorting operation can be performed. In addition, if the order information of the same priority order is the same for the product to be transported on the transport line and the product to be transported on the evacuation line, the same priority order as that of the product to be transported on the previous unloading line is given priority. Since it is sent to the carry-out line, it is possible to prevent the product to be transported from staying in the retreat line and to prevent the product to be transported from retreating to the retreat line.

  Further, when a plurality of reading positions are provided in the transfer line so that the first reading means can read the identification information of the article to be transferred that has arrived at each reading position, the first reading means can read the first information at the plurality of reading positions. The determination means is set so that the rank information of the identification information given to the article to be conveyed read by the reading means matches the corresponding rank information of the identification information stored in the storage means, and the first reading means The rank information with the highest priority in the identification information of the conveyance target product at the reading position closest to the selected conveyance means read by the image does not match the corresponding rank information in the identification information stored in the storage means, and If the rank information with the highest priority of the identification information of the conveyance target product at another reading position matches the corresponding rank information in the identification information stored in the storage means, the storage means stores it. The determination means determines that the transport target product on the transport line is retracted to the retreat line until the transport target product whose priority information matches the other information arrives at the reading position closest to the selected transport means. Can be.

  As described above, the highest priority order information of the identification information of the transport target product at the reading position closest to the selected transport means in the transport line matches the corresponding order information in the identification information stored in the storage means. Even if not, when the highest priority order information of the identification information of the conveyance target product at another reading position in the conveyance line matches the corresponding order information in the identification information stored in the storage means By moving the product to be transported on the transport line to the retreat line, it is possible to preferentially send the product to be transported with the highest priority to the carry-out line, enabling accurate and detailed sorting of the products to be transported. It becomes.

  In addition, as a product to be transported, it is not limited to a game board to which various members as in the embodiment are attached. For example, any finished product as a gaming machine or any other member related to the manufacturing of a gaming machine may be used. Even if it is a thing, it is employable. In particular, in the case of a game board or a completed game machine that can be a target of sorting work in a shipping process or the like, there is an advantage that a product to be transported can be efficiently sorted and transported. Furthermore, the gaming machine is not limited to a pachinko machine, and the present invention can be applied to slot machine machines, arrange ball machines, and other various gaming machines. Note that the present invention is not limited to the case where the conveyance target product that has been subjected to the inspection work is conveyed toward the shipping process, but can be applied to various conveyance processes of the conveyance target item in the gaming machine manufacturing line.
