Abstract
The utility model provides a servo-tracking controlled conveying car which is characterized in that the side face of a car body is provided with a Y-axis servo motor for loading and unloading goods, an X-axis servo motor is arranged below the car body, the Y-axis servo motor and the X-axis servo motor are respectively connected with a first encoder and a second encoder, the inside of an electric control box is provided with a programmable controller, and the input end of the programmable controller is respectively connected with the output ends of the X-axis servo motor, the Y-axis servo motor, the first encoder and the second encoder. The servo-tracking controlled conveying car provided by the utility model has the advantages that: because of the application of a servo drive control technique, the accuracy and reliability of each address of the conveying car are realized, the control accuracy is improved, and the flexibility of servo tracking is also improved; and the continuous closed-loop speed regulation/control of the conveying car is realized, so that the conveying car has stable and quick starting performance and braking performance. The range of application of the conveying car is expanded, therefore, the conveying car can be widely applied to automated stereoscopic straight/annular-rail garages.
Description
Technical field
The utility model relates to a kind of servo tracking control transport trolley, is used for automatic stereowarehouse, can make transport trolley positioning control quick and precisely when operation, thus the precision and the operational efficiency of the tracking Control that the raising transport trolley is in operation.
Background technology
The transport trolley location is general at present adopts optoelectronic switch and laser ranging to locate.Wherein, optoelectronic switch is to position through reflective sheeting, and localization method is simple and economical, but its shortcoming be, belong to discrete relative positioning, sensitivity is low, bearing accuracy is low, operational shock is bigger, in high-speed cruising, is prone to situation such as the location is inaccurate.And the laser ranging location is to adopt laser ranging to position, and belongs to continuous absolute fix, and its bearing accuracy is high, but shortcoming is on the track in straight tunnel, to use, and can't apply to become in the automatic stereowarehouse of track or circular orbit.Therefore, no matter adopt the optoelectronic switch location, or the laser ranging location all there be weak point and shortcoming separately.
Summary of the invention
The purpose of the utility model provides a kind of application scenario of widening, and improves the accuracy of control and the transport trolley of operational efficiency.
In order to achieve the above object; The technical scheme of the utility model has provided a kind of servo tracking control transport trolley; Comprise the car body of being located on the track; Two ends at car body are respectively equipped with impact damper, swing to device and electric control box and are located on the car body, it is characterized in that: be equipped with in the side of car body and be used for the Y axle servomotor of unloading goods; X axle servomotor is housed below car body; Y axle servomotor and X axle servomotor link to each other with first scrambler and second scrambler respectively, in electric control box, are provided with Programmable Logic Controller, and the input end of Programmable Logic Controller connects the output terminal of X axle servomotor, Y axle servomotor, first scrambler and second scrambler respectively.
The advantage of the utility model is: use the servo-drive control technology, realized accuracy and the reliability of transport trolley to each address, improved control accuracy, also improved the dirigibility of servo tracking; Realized the continuous closed-loop VSC of transport trolley, made transport trolley have the startability and the braking ability of quick and stable.Improved the application scenario of transport trolley, can be widely used in straight way, the circular orbit automated three-dimensional storehouse.
Description of drawings
A kind of servo tracking control transport trolley synoptic diagram that Fig. 1 provides for the utility model.
Embodiment
For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
As shown in Figure 1; A kind of servo tracking control transport trolley that the utility model provides comprises the car body of being located on the track 11, is respectively equipped with impact damper 9 at the two ends of car body; Swing to device 10 and electric control box 8 is located on the car body; Be equipped with in the side of car body and be used for the Y axle servomotor 6 of unloading goods, X axle servomotor 7 is housed below car body, Y axle servomotor 6 and X axle servomotor 7 link to each other with first scrambler 3 and second scrambler 2 respectively; In electric control box 8, be provided with Programmable Logic Controller, the input end of Programmable Logic Controller connects the output terminal of X axle servomotor 7, Y axle servomotor 6, first scrambler 3 and second scrambler 2 respectively.
In the present embodiment, also be provided with a touch-screen, touch-screen connects Programmable Logic Controller.During use; Draw a Profibus-DP bus from the DP interface of Programmable Logic Controller; Touch-screen, X axle servomotor 7, Y axle servomotor 6, first scrambler 3 and second scrambler 2 are connected on the Profibus-DP bus; Form a Profibus-DP communication network, and, realize data communication its corresponding components and parts through visiting different DP bus addresss for each element that is connected on the DP network all distributes different DP bus addresss.Simultaneously, carry out the programming of PLC with Programmable Logic Controller statement list language, and operate on the Programmable Logic Controller, automatically transport trolley is positioned and VSC, thereby realized control of transport trolley hi-Fix and VSC.
