Description

  The present invention conveys a carriage loaded with a plurality of articles to an article storage place along a preset route, and instructs a stop position of the carriage to an operator who supplies each article to a predetermined article storage place. In particular, the present invention relates to the presentation of a stop position of a carriage for the convenience of an operator.

  When a part is received from a supplier in a vehicle assembly factory, each part is supplied to a predetermined part place and used in a predetermined assembly process. The work of transporting and supplying the parts to the parts storage is performed according to a predetermined supply course and schedule set in the monthly transportation plan. Specifically, the work is performed according to the following procedure.

  First, when a part is received from a supplier, the part is loaded on an article conveying cart (hereinafter simply “cart”). When the number of incoming parts is large, a plurality of carts are prepared and loaded sequentially. When the predetermined time indicated on the diagram is reached, a parts supply instruction list showing the parts loaded on the carriage and the parts storage to which each part is supplied is issued. The operator connects a cart with parts loaded on the towing vehicle. If the parts are loaded on multiple trolleys, the trolleys are connected in tandem. Then, the worker conveys the tow truck along a predetermined supply course, stops the tow truck at the part supply destination with reference to the received parts supply instruction list, and gets out of the tow truck to search for a corresponding part. . Then, the found parts are taken out from the carriage and supplied to the parts storage. When the parts supply to the parts storage is completed, the vehicle gets into the towing vehicle and heads for the next supplier.

  As described above, the worker conveys the towing vehicle along a predetermined route and supplies the parts to the corresponding parts storage.

JP 2004-1949 A

  However, conventionally, there has been a case where it is necessary to walk more than necessary for supplying parts. An example will be described as to how far the worker walks during the component supply operation.

  FIG. 9 shows a towing vehicle 2, three carts 4 connected to the towing vehicle 2 in a column, and a parts storage 6 serving as a supply destination of each part. In addition, as can be understood from the content example of the parts supply instruction list shown in FIG. 9, the worker supplies D parts at address 1, C parts at address 2, A parts and B parts at address 3, respectively. Will do. Accordingly, the operator causes the tow vehicle 2 to be conveyed according to the supply course and stopped at the first address that reaches first. And as shown to Fig.9 (a), an operator moves to the 3rd car, takes out D components, and carries it to the 1st address. Here, after supplying the parts, the vehicle returns to the loading vehicle and then returns to the towing vehicle.

  The worker gets on the tow truck 2 and transports it to the second address as the next supply destination. And after stopping, as shown in FIG.9 (b), an operator moves to the 2nd car, takes out C parts, and carries it to the 2nd address. Here, the worker carries the B part loaded in the second car to the third address.

  An operator gets on the tow truck 2 and transports it to the third address which is the next supply destination. And after stopping, as shown in FIG.9 (c), an operator moves to the 1st car, takes out A components, and carries it to the 3rd address.

  Now, calculate the walking distance of the worker. For example, it is assumed that the total length of each carriage 4 is 1, and the interval of each component storage 6 is 1. As for the walking distance, only the traveling direction of the carriage (the arrangement direction of the parts storage 6) is obtained, and the distance in the interval direction between the carriage 4 and the parts storage 6 is ignored. The length of the towing vehicle 2 is also ignored. The parts outlet of each truck is assumed to be in the center of the truck. Therefore, the movement distance when the worker who gets off the towing vehicle takes out the parts from the first car is 0.5 (= 1/2) half the length of the carriage, and the movement distance when the parts are taken out from the second car is the whole of the first car And half the length of Car 2 (1.5) (= 1 + 1/2). In addition, it is assumed that the component supply port of each component storage 6 is in the center of the storage.

  First, as shown in FIG. 9 (a), when the towing vehicle 2 is stopped at the first address, the moving distance from the towing vehicle 2 to the third car is 2.5 one-way and the D parts from the third car to the first address. Since the carrying distance is 2 one way, the walking distance for supply from the third car is 9 (= (2.5 + 2) × 2). As shown in FIG. 9 (b), when the tow truck 2 is stopped at the second address, the moving distance from the tow truck 2 to the second car is 1.5 one way, and the C parts from the second car to the second address are as follows. Since the transportation distance of the B parts from Car 1 and Cars 2 to 3 is one way 2, the walking distance for supply from Car 2 is 9 (= (1.5 + 1 + 2) × 2). Similarly, as shown in FIG. 9C, when the towing vehicle 2 is stopped at the third address, the moving distance from the towing vehicle 2 to the first car is 0.5 one way, and the A parts from the first car to the third address are Since the transportation distance is 0 one way, the walking distance for supply from the first car is 1 (= (0.5 + 0) × 2).

  From the above, the total total walking distance of the worker when the A part is loaded on the first car, the B and C parts on the second car, and the D part on the third car is 19 (= 9 + 9 + 1). Become.

  Based on the above example, for example, in order to supply the D part to the predetermined part 1 part storage place 6, it is more convenient to stop the towing vehicle 2 at the third place instead of the first place. This is because the No. 3 car loaded with D parts can be stopped in front of the first address, so that the transport distance can be reduced to zero.

  However, in the past, information on which parts are loaded on which cart has not been provided to the worker, so it is best to stop the towing vehicle in terms of work efficiency. I couldn't judge. Further, the stop position may be instructed without informing the component loading cart, but in the past, such an instruction has not been given.

  In the above description, for the sake of convenience, the case where three trucks are connected is taken as an example. However, since 6 to 7 trucks are actually connected, the walking distance when supplying the last loaded component is The distance cannot be ignored, which may lead to an increase in workload and a reduction in work efficiency.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a stop position indicating method and a stop capable of indicating a suitable stop position for an operator who supplies an article to an article storage place. The object is to provide a position pointing device.

  In order to achieve the above object, the stop position instruction method according to the present invention transports a carriage loaded with a plurality of articles to an article storage place along a preset route, and each article can be determined in advance. In a stop position instruction method for instructing a stop position of a carriage to an operator to be supplied to the article storage area, the carriage information including the size of the carriage is associated with the carriage and the article loaded on the carriage. Based on the information and position information of each article storage area, all articles having a walking distance obtained by the movement distance when the operator takes out the article from the carriage and the transport distance when supplying the extracted article to the article storage area A stop position determining step for obtaining a stop position of the carriage with the shortest total of the vehicle, and a notification step for notifying an operator of instruction information indicating the stop position of the carriage and an article to be supplied at the stop position. That.

  In addition, the stop position determining step includes an accepting step for receiving an array of carriages when transported, identification information of articles loaded on each carriage, and a position specifying that specifies a stop position with the shortest walking distance for each article. And an information generation step of generating article supply instruction information specifying an article to be supplied from each stop position for each stop position specified by the position specifying step.

  The stop position indicating device according to the present invention is for a worker who transports a carriage loaded with a plurality of articles to an article storage site along a preset route and supplies each article to a predetermined article storage site. In the stop position indicating device for indicating the stop position of the carriage, means for storing the carriage information including the size of the carriage, means for storing the loaded article information in which the carriage is associated with the article loaded on the carriage, It is obtained by means for storing the position information of each article storage, and a movement distance when an operator takes out the article from the carriage and a transport distance when supplying the extracted article to the article storage based on each information. Stop position determining means for obtaining the stop position of the carriage with the shortest total of all articles of the walking distance, and notification means for notifying the operator of the stop position of the carriage and instruction information for instructing the article to be supplied at the stop position Have It is characterized in.

  ADVANTAGE OF THE INVENTION According to this invention, the walk distance of the operator who conveys and supplies articles | goods to a predetermined article storage place can be shortened. As a result, the workload can be reduced.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing an embodiment of a stop position indicating device according to the present invention. FIG. 1 shows an information terminal device 10 mounted on the tow vehicle 2 and a stop position indicating device 20 in the present embodiment.

  The stop position indicating device 20 includes an information receiving unit 22, a stop position setting processing unit 24, and an information transmitting unit 26. Moreover, it has the memory | storage parts 28-34 which memorize | stores each information of loading components information, trolley | bogie information, storage location information, and supply route information. The information receiving unit 22 receives information input at a predetermined place where the received parts are loaded on the cart, generates loaded part information, and registers the information in the loaded part information storage unit 28. The stop position setting processing unit 24 obtains the stop position of the cart that provides the shortest total walking distance when an operator takes out the components from the cart and supplies them to the respective component locations based on various information described later. The worker's walking distance is obtained by the sum of the movement distance from the operator's tow truck to the carriage and the transport distance when transporting and supplying the picked-up parts to the corresponding parts storage, as in the conventional example. The information transmission unit 26 wirelessly transmits component supply instruction information to the worker to the information terminal device 10 mounted on the towing vehicle 2.

  The stop position indicating device 20 can be realized by a general-purpose computer such as a personal computer (PC) having a wireless communication function. The storage units 28 to 34 can be realized by a storage device such as a hard disk drive mounted on a PC. However, the storage units 28 to 34 are not necessarily mounted on the stop position indicating device 20. That is, it is only necessary to be configured to be able to access various information held externally via a network.

  On the other hand, the information terminal device 10 mounted on the tow vehicle 2 includes an information receiving unit 12, an information processing unit 14, and a display unit 16. The information receiving unit 12 receives the component supply instruction information transmitted from the stop position indicating device 20 by radio. The information processing unit 14 displays the component supply instruction information received by the information receiving unit 12 on the display unit 16. The display unit 16 is configured with a liquid crystal screen or the like.

  The information terminal apparatus 10 can be realized by a general-purpose computer such as a personal computer (PC) having a wireless communication function or a portable information terminal apparatus carried by each worker.

  FIG. 2 is a diagram showing an example of the contents of the cart information in the present embodiment. The cart information includes at least the total length of each cart as information on the size of the cart. This information is used to calculate the movement distance of the worker. In the present embodiment, as in the conventional example, the distance in the interval direction between the carriage and the parts storage is neglected, so that the entire length is sufficient as the carriage information. However, if the parts take-out port of the truck is not installed in the central part of the truck, or other data is required when calculating the movement distance of the worker, such as connecting the truck by a method other than the column The data will also be included in the cart information. For convenience, the length of the towing vehicle is ignored as in the conventional example, but if it is taken into account, information on the towing vehicle necessary for calculating the moving distance is registered in advance.

  FIG. 3 is a diagram showing an example of the contents of the placement information in the present embodiment. In this embodiment, an address is assigned to each component storage. In the present embodiment, each position information in the factory premises to which the present embodiment is applied can be specified by coordinate data. Accordingly, the placement information is configured by associating an address for identifying each component place with data indicating position coordinates used by the computer for calculating the walking distance, and further associating the number of the component supplied to each part place. The

  FIG. 4 is a diagram showing an example of the contents of supply route information in the present embodiment. The supply route information is information indicating the above-described supply course with coordinate data so that the computer can recognize it. Assuming that the supply course in the present embodiment is determined by continuous straight lines, the supply route information can be expressed by the coordinate data of the end points of each straight line. Each component place is located on an end point set in the supply path information or a straight line connecting the end points. The cart will also stop on the supply course.

  The above cart information, storage location information and supply route information need to be set and registered in advance before the stop position of the cart is determined. The loaded parts information and the parts supply instruction list to be transmitted to the towing vehicle are information generated in the course of processing and will be described later.

  Next, a series of processes for determining the stop position of the carriage and notifying the operator in the present embodiment will be described with reference to the flowchart shown in FIG.

  When a part is received from the supplier, the part is loaded on the carriage at a predetermined loading place. When the number of incoming parts is large, a plurality of carts are prepared and loaded sequentially. When an operator loads a part on a cart, the component to be loaded and each identification number of the cart on which the component is loaded are associated so that it can be understood which component is loaded on which cart. When the predetermined time indicated on the diagram is reached, the operator connects the cart with the parts loaded on the towing vehicle. If the parts are loaded on multiple trolleys, the trolleys are connected in tandem. Then, the worker wirelessly transmits the above-described information associating the parts with the cart and information for clarifying the connection order of the cart to the stop position indicating device 20. The device for transmitting information to the stop position indicating device 20 may be realized by an information terminal device installed at a predetermined loading place, or may be realized by an information terminal device carried by an operator. .

  In the stop position indicating device 20, the information receiving unit 22 receives information sent in response to the operator's operation, generates loaded part information, and registers it in the loaded part information storage unit 28 (step 101). An example of the contents of the loaded parts information is shown in FIG. 6, and the information receiving unit 22 identifies the truck number for identifying the truck and the parts loaded on each truck based on the received information in the order of connection of the truck. Loaded part information is generated by associating with the part number. In this embodiment, it is assumed that the A part is loaded on the first car, the B and C parts are placed on the second car, and the D part is placed on the third car as in the conventional example.

  In order for the stop position setting processing unit 24 to obtain the stop position of the cart that minimizes the total walking distance of the worker, it is only necessary to know the connecting order of the cart and which parts are loaded on which cart. The timing at which the information receiving unit 22 receives is not particularly limited. That is, the worker may send the information on the set of the carriage and the part to the stop position indicating device 20 every time the part is loaded on the carriage, or the parts are transported and supplied according to the diagram. You may make it send in bulk immediately before.

  Subsequently, the stop position setting processing unit 24 determines the stop position of the carriage in the following procedure. First, the stop position setting processing unit 24 calculates the movement distance from the tow truck to each carriage for each part included in the loaded part information (step 102). This moving distance can be obtained by referring to the cart information and the loaded component information. That is, first, since the A part is loaded as a No. 1 car on the No. 1 carriage 1 connected to the towing vehicle, the moving distance is 0.5. Since the B part and the C part are loaded on the truck No. 2 having a total length of 1 connected to the towing vehicle as the second car, the moving distance is 1.5 (= 1 + 0.5). Since the D part is loaded as a No. 3 car on the No. 3 truck 1 connected to the towing vehicle, the moving distance is 2.5 (= 1 + 1 + 0.5).

  Subsequently, the stop position setting processing unit 24 calculates the transport distance from the loaded cart to the component storage for each component included in the loaded component information (step 103). This transport distance can be obtained by referring to the placement information, the supply route information, and the loaded part information. The all stop positions are all candidate positions for stopping the carriage on the supply course. Although details regarding the stop position of the carriage will be described later separately, here, for the sake of convenience, the position corresponding to each component place is assumed. In addition, the positional relationship between each component place and the carriage on the supply course can actually be calculated from coordinate data, but here, the interval between each part place is set to 1 as in the conventional example.

  First, in this embodiment, since the stop position of the carriage is set to a position corresponding to each component place for convenience, the worker stops in order before the first place, the second place,. Can be made. The description will focus on the A part. When the carriage loaded with the A part is stopped before the first address, the transport distance to the third address is two. Next, when stopped before address 2, 1 when stopped before address 3, 0 when stopped before address 4, 1 when stopped before address 5, and 2 The transport distance is calculated for all stop positions (up to address n). The description will be made focusing on the B component. When the carriage loaded with the B component is stopped before the first address, the transport distance to the third address is three. Next, when the vehicle is stopped before the second address, the transport distance is calculated for all stop positions (up to the nth address).

  When the transport distance from all the stop positions is calculated for each part, the stop position setting processing unit 24 specifies the minimum transport distance and the stop position that is the minimum transport distance for each part (step 104). For example, the minimum transport distance in the A part is 0, which is when it is stopped before the third address.

  When the movement distance and the transport distance for each part are obtained, the stop position setting processing unit 24 summarizes which parts are taken out from the loading cart for each stop position and transported to the corresponding parts storage. Thereby, component supply instruction information is generated (step 105). The output result of the generated component supply instruction information becomes a component supply instruction list. An example of the content of the component supply instruction information is shown in FIG. 7, and the following can be understood from FIG. That is, since the information is registered in the parts supply instruction information in the order of stopping, the operator first stops the towing vehicle at “3rd address” and “A part loaded on the first car is set at 3rd address. "Supply", "Supply C parts loaded in Car 2 to address 2," and "Supply D parts loaded in Car 3 to address 1." Subsequently, the tow vehicle is stopped at “address 4” and “the B parts loaded in the vehicle 2 are supplied to address 3”. When supplying a plurality of parts from the same stop position, the stop position setting processing unit 24 arranges the parts so that the movement distance is minimized. Specifically, they may be arranged in the order in which the carts are connected.

  When the stop position setting processing unit 24 generates the component supply instruction information having the above contents, the stop position setting processing unit 24 passes the information to the information transmission unit 26. In addition, you may make it pass to the information transmission part 26 via a memory | storage means. Upon receiving the component supply instruction information, the information transmission unit 26 transmits the component supply instruction information to the information terminal device 10 (step 106).

  When the information receiving unit 12 in the information terminal device 10 receives the component supply instruction information sent from the stop position indicating device 20, the information processing unit 14 displays it on the display unit 16 as a component supply instruction list. Or you may make it print from the printing apparatus which is not illustrated.

  The operator refers to the parts supply instruction list, stops the tow vehicle at the designated stop position, and transports the designated parts to a predetermined parts place.

  Here, a specific example is shown. FIG. 8 is a diagram corresponding to FIG. 9 used in the conventional example. FIG. 8 shows the towing vehicle 2, the three carts 4 connected to the towing vehicle 2 in a column, and the parts storage 6 as a supply destination of each part, as in FIG. 9. The number of parts loaded on each carriage, the loading carriage, and the corresponding parts storage are the same as in the conventional example.

  The operator transports the tow truck 2 according to the supply course, and first stops the tow truck 2 at address 3 as shown in FIG. Then, the worker gets off the towing vehicle 2 and moves to the first car, takes out the A part, and carries it to the third address. Also in this embodiment, after the parts are supplied, it is temporarily returned to the loading cart. Subsequently, the operator moves from the first car to the second car according to the contents of the parts supply instruction list, takes out the C parts, and carries them to the second address. Furthermore, move from No. 2 car to No. 3 car, take out D parts and carry them to No. 1. Thereafter, the operator returns from the third car to the towing vehicle 2.

  The worker gets on the towing vehicle 2 and transports it to the fourth address as the next instruction destination. And after stopping, as shown in FIG.8 (b), an operator moves to the 2nd car, takes out B parts, and carries them to the 3rd address.

  Here, the walking distance of the worker is calculated.

  First, as shown in FIG. 8A, when the towing vehicle 2 is stopped at address 3, the moving distance from the towing vehicle 2 to the first car is 0.5, and the moving distance from the first car to the second car is 1 The travel distance from Car 2 to Car 3 is 1, and the travel distance when returning from Car 3 to Tow Truck 2 is 2.5, so the travel distance when stopping at No. 3 is 5 (= 0.5 + 1 + 1 + 2.5) It is. Each component is 0 (= 0 × 2 + 0 × 2 + 0 × 2) because the transport distance from each cart 4 to each component storage 6 is 0. Therefore, the walking distance when stopping at address 3 is 5 (= 5 + 0).

  Next, as shown in FIG. 8B, when the towing vehicle 2 is stopped at the fourth address, the moving distance from the towing vehicle 2 to the second car is 1.5 one way, so the movement when stopped at the fourth address. The distance is 3 (= 1.5 × 2). And since the transportation distance from the 2nd car to the corresponding parts storage 6 is 0 for B parts, the transportation distance when it stops at the 4th address is 0 (= 0 × 2). Therefore, the walking distance when stopping at address 4 is 3 (= 3 + 0).

  From the above, in this embodiment, the total sum of the walking distance of the worker when the A part is loaded on the first car, the B part and the C part on the second car, and the D part on the third car is 8 (= 5 + 3).

  According to the present embodiment, the total walking distance under the same conditions as in the conventional example is 8, which can be significantly reduced compared to 19 in the conventional example.

Embodiment 2. FIG.
In the first embodiment, the position where the transport distance is minimized in the process of generating the component supply instruction information is determined as the stop position of the component (step 104 in FIG. 5). In the first embodiment, since it is a condition that the current position corresponding to the component place is a candidate for the stop position, a position where the transport distance is 0 is always selected. However, depending on the number and configuration of parts loaded on the carriage, even if the transportation distance can be minimized to zero, the movement distance from the tow truck to the predetermined carriage increases, and the calculation is based on the movement distance and the transportation distance. The walking distance is not always the optimum value (minimum value). For example, as illustrated in FIG. 9B of the conventional example, if the piggyback is carried on the supply of the C component and the B component is carried to the next component storage site, the moving distance is reduced even if the carrying distance increases. I can.

  In the present embodiment, as described above, the position where the transport distance is 0 is not limited to the stop position of the part, but remains as a stop position candidate from the stop position to one stop position before and after the stop position. I asked for the distance. As a result, the minimum walking distance can be obtained more reliably.

  However, since the transport distance is the distance that the operator carries the parts, it may be desirable to prioritize the transport distance to be 0 rather than minimizing the total walking distance depending on the weight of the parts and the quantity to be carried. Accordingly, the weight of the component can be set as a condition for determining the stop position, and the setting condition is taken into consideration when generating the component supply instruction information. Thereby, it is possible to instruct a stop position more suitable for the operator.

  In this case, it is assumed that there is a stop position candidate up to one stop position before and after, and the optimal solution is assumed to be in the stop position where the transport distance is 0 or in the parts storage place one before or one after. In this embodiment, the stop position candidates are left up to one stop position before and after, but the stop position candidates may be expanded two times before (after) or three times before (after).

  By the way, in each said embodiment, it was on condition that the immediate position corresponding to a components place is made into the candidate of a stop position. However, it may be possible to minimize the walking distance by stopping at an intermediate position between the adjacent component places instead of the current position corresponding to the parts place. In fact, it is possible to stop the vehicle if it is on a supply course excluding a part where stoppage is prohibited, such as at an intersection with a pedestrian passage such as between parts storage.

  Therefore, the condition that the current position corresponding to the parts place is a candidate for the stop position is removed, and the stop position that minimizes the walking distance is determined with all the positions that can be stopped on the supply course as candidates for the stop position. It may be.

  As a specific process, for example, a 1 m stop position (candidate) is advanced on the supply course with reference to the supply route information. And a movement distance and a conveyance distance are calculated for every component in a stop position (candidate). Since the position of the parts place and each position that is a candidate for the stop position of the supply course are defined as coordinate data, it can be basically calculated by the same calculation method as in the above embodiments. Then, the travel distance and the transport distance are calculated in the same manner by further advancing the 1 m stop position (candidate). In this way, the stop position (candidate) is shifted forward by 1 m and finally the optimum stop position is obtained. Of course, the interval of 1 m is an example. In order to reduce the processing load, the interval may be widened, and in order to further improve the accuracy, the interval may be narrowed. Furthermore, the stop positions (candidates) need not be equally spaced.

  As described above, if the entire supply course is set as a stop position candidate, the load required for the calculation is enormous, but the stop position where the walking distance is minimized can be surely found.

  Further, when attention is paid to the work load, not only the walking distance focused in each of the above embodiments, but also getting on and off the towing vehicle is considered as a load on the worker. Since the number of times of getting on and off the tow vehicle is equal to the number of stops of the tow vehicle, the number of stops may be set as a condition for determining the stop position to determine the stop position.

  In the present embodiment, the case where the parts received from the supplier in the vehicle assembly factory are supplied to the predetermined parts storage place has been described as an example. However, the application of the present invention is limited to such a case. There is nothing.
