JP-A-5-177472

  However, the range of component supply devices to be managed by a single operator is limited to component supply devices that belong to a group pre-assigned to one dedicated information code reader. Since the remaining number of parts in all the parts supply apparatuses is displayed, it is very difficult for the operator to instantly grasp the remaining number of parts in the parts supply apparatus within the range that he is in charge of.

  It is an object of the present invention to provide a remaining component number management method and a remaining component number management device that make it easy to grasp the remaining component number in a component supply device within the range handled by an operator.

  The component remaining number management method according to claim 1 includes a plurality of information code readers that read information codes related to components to be replenished to a component supply device belonging to a pre-assigned set, and the components supplied by each component supply device This is a method for managing the remaining number of parts in a production system mounted on a board, wherein the remaining number of parts in each component supply apparatus is displayed by being classified into groups assigned to the same information code reader.

  The remaining component number management method according to claim 2 is the remaining component number management method according to claim 1, wherein the component supply devices are arranged in ascending order of the remaining number of components in a set assigned to the same information code reader. Display side by side.

  According to a third aspect of the present invention, there is provided a component remaining number management device, comprising: a component supply device that supplies a stored component to a component mounting device; A component remaining number management device in a production system that includes an information code reader and mounts a component supplied by each component supply device on a board, and calculates a remaining number of components in each component supply device; and Remaining number display means for displaying the remaining number of parts in each component supplying apparatus by classifying them into groups assigned to the same information code reader is provided.

The component remaining number management device according to claim 4 is the component remaining number management device according to claim 3, wherein the remaining number display means is a remaining number of components in a set assigned to the same information code reader. The component supply devices are displayed side by side in ascending order.

  Since the remaining number of parts in the production system is displayed separately for each set of parts supply devices assigned to the information code reader, the operator can replenish the parts within the range of the parts supply device that he / she manages. The necessary order can be grasped in advance, and replenishment parts can be prepared in advance. As a result, the work efficiency is improved and a situation such as production stoppage due to a delay in replenishment is avoided.

  Embodiments of the present invention will be described with reference to the accompanying drawings. 1 is a diagram showing a configuration of a production system according to an embodiment of the present invention, FIG. 2 is a block diagram illustrating configurations of a management device and a component mounting device according to an embodiment of the present invention, and FIG. 3 is displayed on a display unit. FIG. 4 is a flowchart showing an example of screen information, and FIG. 4 is a flowchart showing a method for managing the number of remaining parts in the production system according to the embodiment of the present invention.

  In FIG. 1, the production system 1 uses a plurality of component mounting apparatuses (here, four component mounting apparatuses M1, M2, M3, and M4 are illustrated) as lower systems, and the plurality of component mounting apparatuses and the bus 2 The management device 3 connected in (1) is configured as an upper system that supervises lower systems. The component mounting apparatuses are connected by a transport rail 4 so that the board can be transported from the upstream component mounting apparatus M1 to the downstream component mounting apparatus M4 via each component mounting apparatus.

  Each component mounting apparatus includes component supply tables TBL1 to TBL8 on both sides of the conveyance rail 4, respectively. Each of these component supply tables TBL1 to TBL8 is provided with a slot for mounting a component supply device such as a tape feeder or a bulk feeder. Each component mounting device receives a component from the component supply device mounted in the slot and receives a substrate. To implement. For example, the component mounting apparatus M1 performs mounting by receiving components supplied from a plurality of component supply apparatuses S1 and S5 mounted in the slots of the component supply tables TBL1 and TBL5 provided on both sides.

  The scanner 1 and the scanner 2 are information code readers that read information codes related to components. The information code is displayed by replacing the specific information regarding the part type, lot number, etc. with a pattern such as a number or a figure. The management device 3 collates parts based on the information code read by the scanner 1 or the scanner 2. Each of the scanner 1 and the scanner 2 is dedicated to one operator, and each operator uses the dedicated scanner 1 or the scanner 2 to collate parts. The information code is not directly attached to the part, but is attached to a carrier such as a carrier tape (reel) or a storage case for storing the part, and reading of the information code regarding the part is attached to the carrier. This is done indirectly by reading the information code.

  The operator defines a range of the component supply table whose work status is to be monitored, and the operator performs component supply and replenishment work in the component supply apparatus mounted on the component supply table determined as the range to be monitored. In the component collation operation, the operator who exclusively uses the scanner 1 reads the information code of the component to be supplied to the component supply device mounted on the component supply table TBL1 to 4 on one side of each component mounting device. The operator who specializes in the scanner 2 reads the information code of the component to be supplied to the component supply device mounted on the component supply table TBL5-8 on the other side.

FIG. 2 is a block diagram showing the configuration of the management apparatus and component mounting apparatus according to the embodiment of the present invention. The management device 3 includes a storage unit 10, a collation unit 11, a totaling unit 12, a remaining number information input unit 13, a total information output unit 14, and a display unit 15.

  The storage unit 10 stores component type data and scanner group data to be assigned to a component supply table for each scanner. Of these, the product type data is data associated with the component supply tables TBL1 to TBL8 for the types of components handled in the production system 1. The scanner group data is data in which a set of component supply devices is assigned to each of the scanner 1 and the scanner 2. The scanner 1 is assigned with component supply devices mounted on the component supply tables TBL1 to TBL4, and the scanner 2 is allocated with component supply devices mounted on the component supply tables TBL5 to TBL8.

  The collation unit 11 identifies the type of part from the information code read by the scanner 1 and the scanner 2 and collates with the type data stored in the storage unit 10. Each component supply device is equipped with an alarm function to notify the operator that the component is out, and the operator who receives the notification will supply a new component. In order to confirm in advance whether the product is an equivalent product (appropriate component), it is necessary to use an exclusive scanner 1 or scanner 2 to read an information code related to the component attached to the supply carrier.

  The totaling unit 12 totals the remaining number of components in all the component supply apparatuses mounted on the component supply tables TBL1 to TBL8 for each scanner group. Here, the remaining number of components for each component supply device mounted on the component supply tables TBL1 to TBL4 assigned to the scanner 1 and the component supply device mounted on the component supply tables TBL5 to 8 assigned to the scanner 2 are used. The total is divided into the number of remaining parts for each part. This totaling unit 12 realizes a remaining number calculating means for calculating the remaining number of components in each component supply device.

  The display unit 15 displays the remaining number of parts counted for each scanner group in real time, including the decrease during the mounting operation. The remaining number information input unit 13 inputs the remaining number information of components sent from all the component supply devices mounted on the component supply tables TBL1 to TBL8 to the counting unit 12 of the management device 3. The tabulation information output unit 14 outputs the remaining number of components for each scanner group tabulated by the tabulation unit 12 to the component mounting apparatuses M1 to M4.

  Each of the component mounting apparatuses M1 to M4 includes a storage unit 21, a remaining number calculation unit 22, and a display unit 23, respectively. The storage unit 21 stores the remaining number of components in a plurality of component supply devices mounted on each of the storage units 21. The remaining number calculation unit 22 calculates the remaining number from the number of parts consumed by the mounting work, and updates the remaining number stored in the storage unit 21. Thereby, the storage unit 21 is in a state where the remaining number in real time including the decrease during the mounting operation is stored, and this remaining number is sent to the remaining number information input unit 13 in real time. The display units 23 are provided on both sides of each of the component mounting apparatuses M1 to M4 with the conveyance rail 4 interposed therebetween, and the remaining number of components sent from the total information output unit 14 is classified and displayed for each scanner group. To do.

  An example of screen information displayed on the display unit 23 is shown in FIG. In this screen information, the scanner group 1 (component supply devices mounted on the component supply tables TBL1 to 4 assigned to the scanner 1) is on the left, and the scanner group 2 (component supply tables TBL5 to 5 assigned to the scanner 2) is on the right. The remaining number of parts is displayed for each scanner group. Each of the component supply tables TBL1 to TBL8 is provided with a plurality of slots, and component supply devices are mounted in these slots. Accordingly, the table number and slot number are displayed on the screen to identify an arbitrary component supply device. Depending on the scale of the production system 1, a very large number of component supply devices belong to each scanner group, so here, the component supply devices with a small number of remaining components are displayed in descending order.

  The display unit 15 provided in the management device 3 and the display unit 23 provided in each of the component mounting devices M1 to M4 respectively display the remaining number of components in a plurality of component supply devices, and classify them for each allocation of information code readers. A display means is realized. In this way, the remaining number of parts in the production system 1 is classified and displayed on the screen for each scanner group, and further displayed in ascending order of the remaining number. Therefore, the operator needs to replenish parts in the scanner group that he is responsible for. It is possible to grasp the order in advance and prepare parts for supply in advance. This improves the work efficiency and does not cause a situation such as production stoppage due to a delay in replenishment.

  FIG. 4 is a flowchart showing a method for managing the number of remaining parts in the production system according to the embodiment of the present invention. When production in the production system 1 starts (ST1), the remaining number calculation unit 22 calculates the remaining number of parts in each component supply device, and updates the remaining number stored in the storage unit 21 (ST2). The remaining number information updated in each of the component mounting apparatuses M1 to M4 is input to the totaling unit 12 of the management apparatus 3 by the remaining number information input unit 13 (ST3). The totaling unit 12 totals update information input from the component mounting apparatuses M1 to M4 for each scanner group (ST4). The management device 3 displays the remaining number counted for each scanner group on the display unit 15 (ST5). In parallel with this, the totaling result in the totaling unit 12 is output to the component mounting apparatuses M1 to M4 by the totaling information output unit 14 (ST6). Each of the component mounting apparatuses M1 to M4 displays the remaining number counted for each scanner group on each display unit 23 (ST7).

  Since the processes of ST2 to ST7 are repeatedly performed during production in the production system 1, the remaining number of parts in each part supply apparatus is displayed in real time in a state of being divided for each scanner group.

  The present invention is useful for managing the remaining number of parts in a production system including a plurality of parts supply apparatuses.
