Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an upstream machining apparatus and a downstream machine when a plurality of machining apparatuses are arranged in series to machine a workpiece. By assigning multiple work elements to the work transfer device placed between the processing equipment, it is easy to build the production line, more flexibly respond to fluctuations in production volume, and improve the quality of processing. It relates to a machining production system for work that can be expected. 2. Description of the Related Art Conventionally, when there are a plurality of machining elements of a work and a required amount of production cannot be secured by one machining apparatus, a plurality of machining apparatuses are arranged in series and arranged.
In addition to the transfer device that supplies the material to the machine processing device arranged at the most upstream, a transfer device such as a work transfer robot is arranged between the upstream machine processing device and the downstream machine processing device. A machining device (hereinafter, abbreviated as a machining device as necessary) shares the machining elements of the work with each other,
It has been common practice to adopt a production line configuration that shortens product tact time by sequentially transferring, transferring, and processing workpieces from upstream to downstream. An example of such a production line configuration will be described below with reference to, for example, a glass substrate chamfering processing line shown in FIG. For example, in a glass substrate, edges of four sides of a rectangular glass substrate are chamfered, and four corners are ground. The flow will be described specifically. The material 1 is transferred from the material shelf to the first processing device 11 by the first transfer device 41 such as a robot, and two horizontal chamfers 1a of the glass substrate are performed. This horizontal chamfering is completed. Then, the component processing material is transferred by the second transfer device 42 to the next second processing device 12 on the downstream side. The other two sides, that is, the chamfer 1b in the vertical direction are performed by this processing apparatus.
Then, next, in the third transfer device 43, the next third processing device 1
3 and four corner processes 1c are performed. When the corner processing is completed, the finished product 2 is transferred to the finished product shelf by the fourth transfer device. [0004] In this way, each of the processing apparatuses has a line configuration in which the grinding processing is divided into parts.
The transfer device is merely responsible for the work elements that are sequentially transferred from the upstream side to the downstream side. However, in such a production line configuration,
More specifically, the production tact of the horizontal chamfer, the vertical chamfer, and the corner processing of the glass substrate are different from each other, but the production tact of the entire processing line is arranged in series. Is determined by one of the longest machining tacts, and a waiting state occurs in another machining apparatus, so that there is a problem that the equipment capacity cannot be used 100%. There is also a problem that if a trouble such as a failure occurs in any one of the processing apparatuses constituting the line, the entire line stops. Further, since a plurality of processing devices partially share the processing of the work, it is possible to produce the entire quality only by combining the respective processing qualities, and to maintain the quality stability. Had problems.
