CROSS-REFERENCE TO RELATED APPLICATION

This application is a National Stage of International Patent Application No. PCT/JP2018/013708, the entire content of which is incorporated herein by reference.

BACKGROUND

Technical Field

The present disclosure relates to a work management system that manages work of resupplying a component storage member to a mounting machine, which mounts components supplied from a component supply device attached with the component storage member on a board, and work of collecting waste materials related to the component storage member, and relates also to a component mounting system including the work management system.

Background Art

A mounting machine mounts electronic components (hereinafter simply referred to as “components”) such as chips and ICs, on a board, such as a printed wiring board, to produce a component mounting board. This mounting machine has a component supply device that can be attached with a component storage member storing the components therein. In production of component mounting boards, a production line made up of a plurality of mounting machines is assembled, and parts are resupplied to the component supply device of each mounting machine according to a state of consumption of the components.

Meanwhile, as the components are consumed, waste materials related to the component storage member are generated at each mounting machine. For example, when the component storage member is a component supply tape, the waste materials include a carrier tape from which the components has been removed, a cover tape peeled from the carrier tape, and a reel having run out of the component supply tape wound around it. If these waste materials are not collected at proper timing, the waste materials overflow a waste material storage area of the mounting machine, raising a concern that it may affect the operation of the mounting machine.

In a conventional case of waste material collection, a worker visually checks the waste material storage area when making a patrol of the production line, and executes waste material collection when considering it necessary. JP 2017-216379 A discloses a component mounting system in which, when a new tape cassette for component supply is attached to a mounting machine, an empty tape cassette having supplied the entire components it carries is collected from the mounting machine. These conventional methods pose a problem that waste materials cannot be collected in a timely manner or that a worker needs to move for the sole purpose of waste material collection.

SUMMARY

Accordingly, the present disclosure provides a work management system that allows efficient execution of resupply work of resupplying a component storage member to a component supply device that a mounting machine has and collection work of collecting waste materials from the mounting machine, and to provide a component mounting system using the work management system.

A work management system according to an aspect of the present disclosure is a work management system that, on a production line including a plurality of mounting machines each provided with a component supply device to which a component storage member is attachable, each mounting machine mounting components supplied from the component supply device on a board to produce a component mounting board, manages resupply work of resupplying each mounting machine with the component storage member and collection work of collecting a waste material related to the component storage member from each mounting machine. This work management system includes a part resupply management unit configured to manage a plan of the resupply work for the component supply devices that the plurality of mounting machines have; and a collection management unit configured to collect waste material data on a state of generation of the waste material at the plurality of mounting machines, thereby managing the collection work to be executed in future, for each of the plurality of mounting machines. The part resupply management unit includes a resupply target specifying unit configured to monitor a state of component supply by each of the component supply devices, and specify a resupply time zone in which the resupply work is allowed to be executed and a target mounting machine to be subjected to the resupply work; and a work planning unit configured to extract a plurality of the target mounting machines with the resupply time zones overlapping each other, and create a work plan to make a patrol of the target mounting machines for executing the resupply work at the target mounting machines. The work planning unit is configured to refer to a state of management of the collection work by the collection management unit, and when a need of the collection work to be executed has arisen at the target mounting machine, create a work plan to execute both the resupply work and the collection work for the target mounting machine.

A component mounting system according to another aspect of the present disclosure includes a plurality of mounting machines each provided with a component supply device to which a component storage member is attachable, each mounting machine mounting components supplied from the component supply device on a board to produce a component mounting board; and the above work management system configured to manage resupply work of resupplying each of the plurality of mounting machines with the component storage member and collection work of collecting a waste material related to the component storage member from each mounting machine.
