Description
Technical field
The invention belongs to stacking machine technical fields, and in particular to the stacking of chest is piled up in a kind of container or cargo
The shovel board of parallelogram connection-rod assistance for lifting mechanism is carried on machine.
Background technology
The stacking machine that chest is piled up in container or cargo being capable of high efficiency, low cost, easy to operate to quantity
Huge all kinds of packing cases carry out automatically piling up chest operation in narrow container or cargo, improve vanning effect
Rate, reduce labor intensity, improve dress compartment operating condition, improve compartment in charging ratio, effectively shorten manufacturing enterprise shipment when
Between；But there are still following defects for existing stacking machine：(1) due to the limitation of shovel board thickness and elevating mechanism size, in compartment
All there are certain spaces can not carry out chest stacking for body top；(2) it is passed in and out for convenience of stacking machine, shovel board or so will reserve enough
Space, lead to close to carriage body two side position that also there are certain spaces can not carry out chest stacking；(3) chest is whole when filling compartment
Row released from shovel board, for prevent lower layer's chest gap stop release chest, there are one stretch out plate, but existing stretchings plate and
Shovel board is the same can not to be suitable for piling up close to the chest of carriage body two side position；(4) the chest blocking mechanism of shovel board front end does not have
Self-locking function causes chest misaligned in shovel board, influences to pile up effect.First three defect is for size chest less than normal
It is especially apparent, it is seen then that a kind of novel shovel board that can overcome aforementioned four defect of design, is vital for stacking machine.

Dynamic pair.
This carries the shovel board of parallelogram connection-rod assistance for lifting mechanism, and operation principle is as follows：
Lift driving motor drives the second driving pulley, hoisting belts 12 and the second driven pulley to rotate through transmission shaft, the
Two driven pulleys band movable slider 11 lifts；To which sliding block 11 drives 23 edge of bottom plate of parallelogram connection-rod assistance for lifting mechanism 20
Rack 10 lifts；Parallelogram connection-rod assistance for lifting mechanism 20 drives shovel board component 30 to move up and down；About 30 shovel board component
When movement, under the weight effect of shovel board component 30,24 head of lever of parallelogram connection-rod assistance for lifting mechanism 20 is downward
It tilts, the lever 24 of bottom is attached on the transverse slat of 23 bottom of bottom plate；When the sliding block 11 of main hoist moves to lowest limit position
When setting, 30 energy close proximity to ground of shovel board component, to ensure the stacking of stacking machine lowermost layer.Parallelogram connection-rod assistance for lifting
The bottom plate 23 of mechanism 20 is along the lever rear support 21 that rack 10 rises to 20 rear end of parallelogram connection-rod assistance for lifting mechanism
Block bearing 27 when touching the frame levers rear support block 13 being fixed in rack 10, sliding block 11 is in hoisting belts 12
Continue to rise under drive, the bottom plate 21 of assistance for lifting mechanism 20 rises with sliding block, and lever rear support 21 is in frame levers rear fulcrum
Under the blocking of block 13, no longer rise, two levers 24 are swung around lever shaft 25, are hinged on the shovel board peace of two 24 front ends of lever
The lever 24 that dress seat 22 drives shovel board component 30 to continue to rise to top is attached on the transverse slat at 23 top of bottom plate, to meet shovel board group
Part rises to the maximum height near or above rack 10, meets the needs for piling up highest point chest.
Shovel board component 30 for convenience of robot palletizer disengaging carriage body needs, width cannot be too wide, pile up chest when again
The full carriage body both sides of 30 yards of shovel board component are asked, so one piece of unpowered lateral accessory plate of shovel board is respectively arranged in 30 both sides of shovel board component
31, the lateral accessory plate of unpowered shovel board 31 is not provided with power；The mechanism of action of the lateral accessory plate of unpowered shovel board 31 is as follows：Work as code
After pile robot enters carriage body, need the chest of stacking when on shovel board component 30 by laterally pushing away draw box mechanism crosswise pushing, chest pushes away
It moves the unpowered lateral accessory plate 31 of shovel board to move to 30 both ends of shovel board component, ensures that chest can pile up carriage body both sides；Work as chest
After releasing shovel board component 30, the unpowered lateral accessory plate 31 of shovel board returns under the reply force effect of return spring 32 close to shovel
The position of board group part 30.
30 bottom of shovel board component is provided with extension ejecting plate component 50, and the stretching plate mounting plate 54 of extension ejecting plate component 50 is being stretched
Under the driving of ejecting plate driving motor 55, released along 30 direction of advance of shovel board component；Extension ejecting plate 52 and two pieces of extension side panel 51
It is released forward with plate mounting plate 54 is stretched out, is also secured to the guide groove fixing axle 53 on the bottom support plate of shovel board component 30 along preceding
The guide groove sliding for stretching out side plate 51, since the guide groove of extension side panel 51 is broken line or curve, so extension side panel 51
Front end under guide groove effect, stretch out 54 end extended of plate mounting plate from trend.The setting of extension ejecting plate 52 prevents lower layer's case
Chest is released in the gap blocking of son；Extension ejecting plate component 50 coordinates the lateral accessory plate 31 of unpowered shovel board to use so that stacking is arrived
The chest of carriage body both sides can also prevent the gap of lower layer's chest from stopping and smoothly releasing.
Blocking linkage 40 is for blocking chest to be palletized on shovel board component 30 so that chest shovel board component 30 most before
Hold marshalling.When the chest on shovel board component 30 needs to release, the countercheck rod driving electric cylinders 42 of blocking linkage 40 push
Drive link 43, drive link 43 push swing rod to swing forward so that drive shaft 49 is rotated around Pivot Point Center drives countercheck rod to connect
The drive rod 48 of bar assembly 45 is swung, to pull block 46 to swing by stop links 47, the blocking being fixed on block 46
41 downward swing open of bar, makes the chest on shovel board component 30 smoothly release；Countercheck rod link assembly 45 is in original state (blocking
State) under, the axis of rotation and stop links 47 at 48 both ends of drive rod are in same plane with the hinged axle center of drive rod 48,
Chest pushes countercheck rod 41 at this time, block 46 cannot be made to generate swing, to generate self-locking.
