Abstract
The utility model discloses a synchronous control structure for an assembly technology section and a fast conveying section of an automobile assembly conveying line, comprising an assembly technology section frequency converter and a fast conveying section frequency converter, wherein the assembly technology section frequency converter is connected with a CC-LINK bus network. The synchronous control structure is characterized in that an analog signal positive-phase output terminal and an analog signal negative-phase output terminal of the assembly technology section frequency converter are respectively connected with an analog signal positive-phase input terminal and a negative-phase input terminal of the fast conveying section frequency converter; and a relay normally open contact is connected between a forward starting terminal and a common input terminal of the fast conveying section frequency converter. Compared with the conventional bus control method, the utility model has the advantages that a frequency converter bus communication expansion module is saved, the precious resources at a bus station are saved, particularly the cost-reducing effect owing to the resources saving at the bus station is reflected at the similar control areas.
Description
Technical field
The utility model belongs to the control structure of car assembling travel line, the assembly technology section of a kind of car assembling travel line of specific design and quick transportation section synchro control structure.
Background technology
On the car assembling travel line, exist two kinds of conveyor zones in assembly technology section and quick transportation section and mode of movement.The assembly technology section is meant device rate adjustable (changing according to productive temp) operator carries out the production erecting work synchronously under the situation of equipment operation transportation section; The transportation section is meant the zone of the car assembling parts being derived or fast workpiece being imported to the assembly technology section fast from load segment fast, and in general the speed of quick fraction is more than 5 times of assembly technology section.If the conveying carrier on the travel line jumps at a slow speed and carry motor fast, because two inconsistent long-time high-frequency operations of motor speed can cause the damage of transfer unit, therefore when conveying carrier enters into soon at a slow speed binding site, must assurance speed unanimity (synchronously).Chang Yong method was that control frequency converter with fast slow speed motor is suspended on the bus network in the past, by total line control with adjust the speed of two conveying motors, and was consistent.There is the cost height in this control method, deficiencies such as control complexity.The terminal connections of frequency converter as described in Figure 1.
Summary of the invention
The purpose of this utility model is to provide a kind of assembly technology section and quick transportation section synchro control structure of simple car assembling travel line, to address the above problem.
The technical solution of the utility model is: the assembly technology section of car assembling travel line and quick transportation section synchro control structure, it comprises assembly technology section frequency converter, quick transportation section frequency converter, assembly technology section frequency converter is connected with the CC-LINK bus network, it is characterized in that analog signal positive output end of assembly technology section frequency converter is connected with negative-phase input with analog signal normal phase input end of quick transportation section frequency converter respectively with analog signal negative lead-out terminal; Fast the just commentaries on classics of transportation section frequency converter starts between terminal and the public input terminal and is connected relay normally open contact.
The utility model is connected the frequency converter of assembly technology section with the CC-LINK bus network, utilize bus mastering mode realization speed to adjust at any time, utilizes the quick transportation section of the frequency converter analog quantity output control frequency converter of assembly technology section; Assembly technology section frequency converter speed is after the bus control break, the analog quantity output valve of himself frequency converter is followed change, the corresponding input value of transportation section frequency converter analog quantity setting is fast followed and is changed, and makes the frequency of quick transportation section frequency converter change, and realizes the purpose of speed synchronization.It is simple in structure, and control is convenient.The utility model is compared with conventional bus control method and is saved a frequency converter bus communication expansion module, saved valuable bus station resource, particularly, more can embody the reduction effect of the resource-effective cost that directly brings of bus station in the place that a lot of similar control zone is arranged.

The specific embodiment
Assembly technology section frequency converter 10 in the present embodiment adopts the FR-E740-0.75-CH frequency converter, and transportation section frequency converter 20 adopts the FR-E740-0.75-CH frequency converter fast.The mouth of assembly technology section frequency converter 10 is connected with assembly technology section motor 30.The mouth of transportation section frequency converter 20 is connected with quick transportation section motor 40 fast.The communication module 50 of assembly technology section frequency converter 10 is connected with the CC-LINK bus network.Analog signal positive output end of assembly technology section frequency converter 10 is connected with negative-phase input with analog signal normal phase input end of quick transportation section frequency converter respectively with analog signal negative lead-out terminal; Fast the just commentaries on classics of transportation section frequency converter starts between terminal and the public input terminal and is connected relay K M2335 open contact.The frequency converter run signal is controlled by relay K M2335.
The frequency converter 1 of motor 3M01 is controlled speed governing by the CC-LINK bus network, and motor 4M02 frequency converter 2 run signal are controlled by relay K M2335, and frequency is exported by the analog quantity of frequency converter 1 and controlled.
