The turnover box 50 sent does straight reciprocating motion along the guide rail 23 on column 111.
Illustrate that turnover box tears the operation process that palletizing apparatus carries out stacking open in the utility model below with a specific embodiment:
When needing stacking, turnover box 50 is entered the transfer unit 30 that the turnover box tears palletizing apparatus open by upstream pipeline;
Before completing to turnover box stacking, movable guide plate 123 is in closed state, stops turnover box for keeping off;In hold assembly 24
When not needing clamping turnover box, clamping jaw 243 is in the open state;Crane 21 is in its lowest order for doing linear reciprocating motion
It sets;
Turnover box 50 along transfer gantry 31, by conveying 32 correcting of guide plate, touch movable guide plate 123 when lived
The gear of action-oriented plate 123 stops, and preset turnover box to level detection sensor issues signal at this time, and transfer unit 30 stops conveying, week
Turnning box 50 is parked in the stacking position immediately below lifting part 20, and the clamping jaw cylinder 244 in lifting part 20 controls clamping jaw at the same time
243 closures, make turnover box 50 be clamped component 24 and clamp;
After hold assembly 24 clamps turnover box 50, the stroke sensor on clamping jaw cylinder 244 issues signal;Receive the signal
Driving equipment 42 starts turning afterwards, and by the connection of power transfering part 43, crane 21 can do linear reciprocation along guide rail 23
Movement: the hold assembly 24 on crane 21 holds turnover box 50 and ramps along guide rail 23, leaves turnover box 50 defeated
Send bracket 31;
After driving equipment 42 starts turning, transfer unit 30 continues to convey, and second turnover box is entered by upstream pipeline
The turnover box tears the transfer unit 30 of palletizing apparatus open;
When driving equipment 42 drives 431 half revolution of first connecting rod, crane 21 reaches highest point, 50 bottom of turnover box
The distance between transfer gantry 31 is greater than the height of a turnover box;Period, when confirmation turnover box 50 and transfer gantry 31 it
Between distance be greater than a turnover box height after, second turnover box just enters stacking position;When second turnover box reaches code
After stack position stops, due to the limit of movable guide plate, second turnover box is in the underface of first turnover box 50, and two
There are prepsetting gaps between chest;
Driving equipment 42 continues to rotate at this time, and the hold assembly 24 on crane 21 clips turnover box 50 along 23 straight line of guide rail
Decline;When declining certain altitude, turnover box 50 is just fallen on second turnover box, the neat stacking success of two chests;Really
Determine after turnover box 50 falls on second turnover box, crane displacement sensor provides signal, and clamping jaw cylinder 244 controls clamping jaw
243 open, no longer clamping turnover box 50;
Driving equipment 42 also is continuing to rotate at this time, and crane 21 continues straight line decline along guide rail 23, and second has enough to meet the need
Case has been stably stacked on turnover box 50.
When driving equipment 42, which just controls first connecting rod 431, to rotate a circle, crane 21 reaches minimum point again;
After crane 21 reaches minimum point again, the clamping jaw cylinder 244 in lifting part 20 controls clamping jaw 243 and is closed,
Make second turnover box be clamped component 24 to clamp;
After hold assembly 24 clamps second turnover box, the stroke sensor on clamping jaw cylinder 244 issues signal;Receive this
Driving equipment 42 starts turning after signal, so that the hold assembly 24 on crane 21 holds second turnover box and turnover box
The 50 2 layers of turnover box pile formed are ramped along guide rail 23, leave transfer gantry 31.
After driving equipment 42 starts turning, transfer unit 30 continues to convey, and third turnover box is entered by upstream pipeline
The turnover box tears the transfer unit 30 of palletizing apparatus open;
……
So in cycles, the turnover box for sequentially entering stacking machine can be piled to 3 layers of turnover box pile, 4 layers of turnover box pile etc.,
And the chest entered at first, in the top, the chest finally entered is in bottom.
After the height of embankment of turnover box pile is met the requirements, sensor 13 detects signal, and driving equipment 42 is stopped rotating, activity
Guide plate cylinder 125 controls movable guide plate 123 and opens to two sides, and transfer unit 30 starts to convey, the turnover box that stacking is completed
Pile advances along transfer unit 30, and into downstream pipeline, so far, the stacking work flow of a turnover box pile terminates.
Illustrate that turnover box tears the operation process that palletizing apparatus carries out bavin pile open in the utility model below with a specific embodiment:
When needing de-stacking, entire operation process is opposite with palletization: turnover box pile along 123 side of movable guide plate into
Enter stacking position, activity-oriented plate closing;Driving equipment 42 rotates, and the hold assembly 24 on crane 21 clips the from the bottom up
Two turnover boxes ramp, and container pile is dismantled;After crane 21 is to highest point, the turnover box of the bottom is by transfer unit
30 send out stacking position;After confirming that the turnover box being transported away leaves stacking position, the hold assembly 24 on crane 21 clips remaining
Turnover box pile continue to decline, reach minimum point;Then clamping jaw is opened, and driving equipment 42 continues to rotate, the folder on crane 21
It holds component 24 and clips second turnover box straight line from the bottom up at this time toward rising, new turnover box pile is dismantled, highest is arrived
The turnover box of the bottom by pipeline sends out stacking position ... repeatedly at this time after point, until container pile is opened completely, institute
There is turnover box successively to enter downstream pipeline with single chest.
According to the technical solution of the utility model embodiment, torn open in palletizing apparatus because using using above-mentioned turnover box
Frame parts is that turnover box is limited and the slider-crank mechanism for utilizing the driving part in above-mentioned apparatus to constitute transports revolution
Turn is changed to the technological means of the linear reciprocating motion of turnover box, in the prior art can not heavier loads turnover so overcoming
Case, the process step of turnover box lifting be complicated, lifting inefficiency, it is inaccurate to turnover box positioning caused by the stacking skills such as unsuccessfully
Art problem, so reach and be able to bear biggish load, structure is simply easily installed, to realize to turnover box safety, high
Effect, the technical effect for fitly carrying out stacking.
Above-mentioned specific embodiment does not constitute the limitation to scope of protection of the utility model.Those skilled in the art answer
Should it is realized that, depend on design requirement and other factors, various modifications, combination, sub-portfolio and substitution can occur.
Any modifications, equivalent substitutions and improvements made within spirit of the present utility model and principle etc. should be included in practical
Within the scope of novel protected.
