Abstract
The invention provides a stroke switch control structure of a chain loader, relating to the technical field of mechanical structures of chain loaders. The stroke switch control structure of the chain loader ensures stable and accurate control of a stroke switch. The stroke switch control structure of the chain loader comprises a tray and the stroke switch and is characterized in that a cam connecting rod is installed at the upper part of an upper contact of the stroke switch and is installed on the seat board through a rotating shaft, the arc surface and the raised contact position of the cam connecting rod are attached to the upper contact tightly, a connecting rod close to the raised end of the cam connecting rod is connected with a pressing wheel, a connecting rod far away from the raised end of the cam connecting rod is connected with a spring, and the bottom surface of the tray is lower than the upper part of the pressing wheel and is higher than the cam connecting rod.
Description
Technical field
The present invention relates to the mechanical structure technical field of chain transfer, be specially stroke switch control structure of chain loader.
Background technology
The main transfer criteria pallet of chain transfer is widely used in the Automatic Warehouse.In its control system, important one is position probing to pallet.It is in the place of needs induction, travel switch is installed, and existing stroke switch control structure of chain loader is seen Fig. 1, when pallet 1 through out-of-date, the bottom of pallet 1 or other parts are pressed onto the feeler lever 3 of travel switch 2, thereby change the state of travel switch 2, pallet 1 relative feeler lever 3, size is larger, Heavy Weight, so break easily feeler lever 3, cause forming the inefficacy of switch 2 so that the control of travel switch 2 unstable, easily make mistakes.
Summary of the invention
For the problems referred to above, the invention provides stroke switch control structure of chain loader, it is so that the control of travel switch is stable, accurate.
Stroke switch control structure of chain loader, its technical scheme is such: it comprises pallet, travel switch, it is characterized in that: the top of the upper contacts of described travel switch is equipped with cam link, described cam link is by being installed on around the shaft seat board, the arc surface of described cam link and the contact position of protrusion are close to described upper contacts, a described end link that protrudes near cam link connects pinch roller, described other end connecting rod linking springs away from the cam link protrusion, the bottom surface of described pallet is lower than described pinch roller top, and the bottom surface of described pallet is higher than described cam link.
After adopting structure of the present invention, during the pallet operation, pressing pinch roller, pinch wheel descending causes the protrusion of cam link to press down, and protrudes to rotate around the axis, the other end connecting rod that protrudes away from cam link rises, protrusion rotates and is pressing the upper contacts of travel switch, so that the travel switch action, this control structure is so that the control of travel switch is stable, accurate.
Description of drawings
Fig. 1 is existing stroke switch control structure of chain loader schematic diagram;
Fig. 2 is structural representation of the present invention.
Embodiment
See Fig. 2, it comprises pallet 1, travel switch 2, the top of the upper contacts 3 of travel switch 2 is equipped with cam link 4, cam link 4 is by 5 being installed on seat board 6 around the shaft, the arc surface of cam link 4 is close to upper contacts 3 with the contact position that protrudes 7, protrudes 7 a end link 8 connection pinch rollers 9 near cam link 4, protrudes 7 other end connecting rod 10 linking springs 11 away from cam link 4, the bottom surface of pallet 1 is lower than pinch roller top, and the bottom surface of pallet 1 is higher than cam link 4.
