Background technology
The sheet metal such as steel plate or iron plate be industry make in it is very common, its advantage be have very strong rigidity with
Hardness, and the drawback is that density is larger, and volume is also larger, causes the quality of steel larger, is not easy to feeding feeding.Tradition is main
To rely on two ways to carry sheet metal, first, manually carry out carrying sheet metal, such a mode be only applicable to size compared with
Small sheet metal;Second, the carrying of steel plate is carried out by auxiliary clamp or driving.Both are required for operator directly right
Sheet metal is operated, there are artificial intensity it is larger and occur Personal Risk's accident a series of problems, such as.
Notification number is that the patent of CN204355781U discloses a kind of steel plate feeder, including organic frame, in rack
Stent, the steel plate loading assemblies for being set up on stent and being set towards rack.Wherein, steel plate loading assemblies, which include, is set up in

Be installed with steel plate upper flitch in the at one end that one end is connected with cylinder, the steel plate upper flitch be equipped with it is some towards rack set
Vacuum cups;Being equipped between the rack and upper flitch can be along the steel plate placement plate of stent longitudinally adjust.
Although above-mentioned patent can realize the automatic transporting feeding of steel plate, vacuum cups is integrally fixed in rack, right
In rough steel plate or when vacuum cups is not at same plane, it can not ensure that whole vacuum cups adsorb steel
Plate, therefore there are security risk.And since the sheet metal of present industrial production is usually all there are punching, inhaled using vacuum
When head adsorbs the sheet metal for having punching, vacuum cups may cover punching, so that can be inadequate there are adsorption capacity
The problem of, there is larger security risk.Therefore, the automatic conveying device of present sheet metal be usually using magnechuck come
Instead of vacuum cups.And utilize magnechuck adsorbing metal plate when, due to magnechuck magnetism can with sheet metal into
Row transmits, so magnechuck easily produces suction to several pieces of sheet metals at the same time, does not reach production requirement, and presence is very big
Security risk.

Disembark structure, the separating mechanism includes fixed link and mobile bar, and fixed link is horizontally placed on the outer wall of cylinder block, fixed link
On slidably connect motion bar, spring is arranged with fixed link, both ends of the spring is connected with cylinder block and motion bar respectively, activity
The lower end of bar is equipped with separating plate, the wedge shaped shape in both ends of separating plate;Mobile bar is horizontally placed on the lower part of the piston rod of cylinder,
End of the mobile bar away from cylinder, which is equipped with separating plate to match somebody with somebody vertically, merges the wedge block for promoting separating plate, and wedge block, which is located at, to be divided
From the top of plate;Controller with horizontal transport mechanism, lifting transmission mechanism, cylinder, magnechuck, pressure sensor, close
Switch is electrically connected;
The technique comprises the following steps:
(1) start horizontal transport mechanism, drive lifting transmission mechanism to move to the surface of sheet metal, then stop;
(2) start lifting transmission mechanism, drive carrying mechanism to move downward, until giving control close to switch feedback signal
Device;
(3) cylinder is started, cylinder piston rod drives magnechuck and mobile bar to move downward, until pressure sensor is fed back
Signal is to controller;
(4) magnechuck, magnechuck adsorbing metal plate are started;
(5) start lifting transmission mechanism and horizontal transport mechanism, drive sheet metal to move to above workbench, Ran Houting
Only;
(6) start lifting transmission mechanism, drive sheet metal to drop on workbench;
(7) stop magnechuck, start cylinder, cylinder is done drawback movement;
(8) start lifting transmission mechanism, drive carrying mechanism to move upwards;
(9) repeat step (1) to (8), starts the carrying of sheet metal next time.
The operation principle of this base case is:Horizontal transport mechanism is driven to do horizontal fortune in frame upper end by controller
It is dynamic, lifting transmission mechanism is transported to the surface of the sheet metal of stacking, since carrying mechanism is positioned at lifting transmission mechanism
Lower end, so carrying mechanism can be located at the surface of sheet metal.Then driving lifting transmission mechanism so that lifting transmission mechanism
Carrying mechanism is driven to decline.Since the lower end of supporting beam is equipped with close to switch, when the spacing close to switch and sheet metal reaches
Certain value, close switch meeting feedback signal is to controller, so that controller stops lifting transmission mechanism, makes under carrying mechanism stopping
Drop.The end of the wedge shape of separating plate is just directed at the gap of two pieces of sheet metals at this time.
Then cylinder is started so that the piston rod of cylinder moves downward.And mobile bar is located on the piston rod of cylinder, so
Mobile bar can move downward, therefore the wedge block of mobile boom end can also move downward.And separating plate is located at the lower section of wedge block
And the wedge shaped shape in separating plate both ends, so wedge block moves downward meeting and the outer end in contact of separating plate wedge shape, wedge block meeting
One horizontal thrust is produced to separating plate, so that separating plate can be moved into the gap of two pieces of sheet metals so that separating plate position
Between two pieces of sheet metals.
Since the piston rod bottom of cylinder is connected with magnechuck, and magnechuck is equipped with pressure sensor, so working as
After magnechuck touches sheet metal, pressure sensor can perceive pressure so as to which feedback signal is stopped to controller, controller
The only action of the cylinder.Pressure sensor on each magnechuck perceives pressure, i.e., each magnechuck with gold
Belong to plate fitting.Then start magnechuck, magnechuck is adsorbed sheet metal.Then lifting conveyer is started
Structure, lifting transmission mechanism drive carrying mechanism to move upwards, are moved upwards so that some magnechucks adsorb sheet metal.By
In separating plate between two pieces of sheet metals, so the suction that magnechuck produces the sheet metal of lower floor is smaller, can not
The sheet metal of lower floor is had an impact.Then using transmission mechanism and horizontal transport mechanism is lifted, sheet metal is transported to
The top of workbench.Then stop magnechuck, start cylinder so that the piston rod of cylinder does drawback movement, while separating plate
Under the action of the spring can be to the movement outside of sheet metal, when the piston rod of cylinder returns to initial position, separating plate can be complete
Positioned at the outside of sheet metal.Lifting transmission mechanism and horizontal transport mechanism are recycled, carrying mechanism is transported to the gold of stacking
Belong to the surface of plate, prepare the carrying of sheet metal next time.
The beneficial effect of this base case is:In the prior art, it is typically directly to transport sucker to lift transmission mechanism
Onto sheet metal, lifting transmission mechanism has a larger inertia force when declining so that when sucker is contacted with sheet metal
Larger impact force can be born, is easily damaged sucker.And this programme is switched by being positioned proximate to so that lifting transmission mechanism declines
It can stop acting to after reaching certain value with the distance of sheet metal, also have a spacing between magnechuck and sheet metal at this time
From avoiding magnechuck and be subject to impact force, so as to protect magnechuck, extend the service life of magnechuck.
This programme sets magnechuck by setting cylinder on adjustable shelf on the piston rod of cylinder, so that often
A magnechuck can move up and down within the specific limits.Even if therefore the surface of sheet metal is not substantially flat,
Each magnechuck also can be adsorbed onto the surface of sheet metal.So that the present apparatus can be to the sheet metal of different size
Carried, possess multifunctionality.
This programme is by setting separating mechanism so that and when cylinder declines, separating plate can enter between two pieces of sheet metals,
So as to prevent magnechuck from being adsorbed to polylith sheet metal, security is improved.
Further as this programme is improved, and the horizontal transport mechanism includes motor, chain, two guide rails and two silks
