A multi-station conveying equipment, including a driving device, a conveyance coupling device, and a station combining device, wherein:
- the station combining device includes a plurality of conveying station mechanisms arranged side by side in proper order corresponding to a plurality of stations, wherein each conveying station mechanism is suitable for placing and supporting a material frame;
- the driving device has a fixing portion fixed relative to the conveying station mechanism and a moving portion reciprocable relative to the fixing portion, and the moving portion can drive a plurality of material frames on the plurality of conveying station mechanisms to move synchronously through the conveyance coupling device;
- and
- the conveyance coupling device comprises at least one set of drawstring shifting fork mechanism, wherein the drawstring shifting fork mechanism comprises a drawstring extending on the plurality of stations along the movement direction of the material frame and a plurality of shifting forks distributed on the drawstring at the positions corresponding to each station;
- the moving portion of the driving device is fixedly connected with the drawstring and can drive the drawstring to reciprocate;
- in one movement direction of the drawstring, the shifting forks are in a force transmission engagement with the material frames to drive the material frames to move, while in the other opposite movement direction of the drawstring, the shifting forks are released from the force transmission engagement with the material frame and no longer drive the material frames;
- wherein the driving device is constructed as a cylinder-driven mechanism which comprises a front fixing plate and a rear fixing plate which form the fixing portion, a moving plate which forms the moving portion and is arranged between the front fixing plate and the rear fixing plate, a connecting arm which fixedly connects the moving plate with the drawstring, a cylinder which drives the moving plate to move, and a guiding assembly which guides the moving plate to move between the front fixing plate and the rear fixing plate;
- the conveying station mechanism comprises a bracket, bottom conveying wheels for supporting and conveying the material frames, a guiding wheel for limiting the material frames to enable the material frames to move forwards linearly, and a riding wheel for supporting the drawstring;
- and
- the drawstring shifting fork mechanism comprises a bottom plate fixed on the drawstring, a pin shaft is fixed on the bottom plate, and the shifting fork can rotate around the pin shaft to be in the position in a force transmission engagement with the material frames or be in the position released from the force transmission engagement with the material frames;
- and wherein only one of the plurality of conveying station mechanisms is equipped with the cylinder-driven mechanism, the multi-station conveying equipment is equipped with two sets of drawstring shifting fork mechanisms, two sides of the moving plate of the cylinder-driven mechanism are respectively welded with a connecting arm, and a drawstring of each drawstring shifting fork mechanism is respectively fixed with one connecting arm so as to drive the material frame from two sides of the material frame.
