Straw bag is put in order automatically, queuing and apparatus for feeding be by material feeding platform, row arrangement, highly arrangement, queuing and adjust five parts such as spacing and form.Structure is seen Fig. 3.
The material feeding platform
The material feeding platform is by wide 3 meters; Long 10 meters chain scraper conveyor or roller conveyor constitute; Its load-bearing is by per 3 meters long of arbitrary place, and 1.5 meters wide table tops bear at least that 30 material bags calculate and the moment impact load design when on traction, transportation and supporting construction, satisfying minimum intensity and rigidity requirement and tolerance and bearing scraper and unload.
The material feeding platform is accepted hay grabbing machine and is caught material and be surrounded by preface or the relatively poor material grasping bag of order, and the hay grabbing machine material of grabbing of will grab bucket is placed on earlier on the half of platform near hay grabbing machine, unclamp grab bucket and upward catching grab bucket; After picking up last layer; Reversing is left the edge of nearly hay grabbing machine one side of lower floor's straw bag until the grab bucket leading edge in the platform projector, falls grab bucket near platform the time; It is motionless to keep grab bucket; The straw bag of nearly hay grabbing machine one side of platform that the mode of advancing with hay grabbing machine will be put down is inwardly shifted onto on second half platform, puts down the straw bag in the hay grabbing machine grab bucket, makes this time catch the array that straw bag on the platform forms one deck ten row three row.This operation will begin after the stop motion of material feeding platform immediately, and accomplishes in before overline begins to move again about 1 minute.Each grabs hay grabbing machine the material that place and wraps on the platform by above requirement operation.Straw bag is put in order automatically, queuing and apparatus for feeding carry out next step conveying after should accomplishing on this basis again.But device is also considered to wrap the disposal ability under the local irregularity situation by the material that a variety of causes causes.
This device material feeding platform should be accepted above-mentioned operating type, and is firm in structure durable.The in heaps little side bag of the irregular arrangement that hay grabbing machine possibly ship, material feeding platform except that should be enough big, platform away from hay grabbing machine one side should be provided with intensity enough block facility, the back material bag in heaps that prevents to unload overflows or hay grabbing machine pushes away the platform that falls when wrapping forward.But the material bag that blocks facility reply motion is enough smooth, does not impact the material contracted affreightment is moving.
The material feeding platform is accomplished separating the 1 meter wide 3 meters long big square formation material bag of each row material bag from platform with the capable collator co-operating in downstream, sends into highly arrangement and queue machine with the attitude of full line.Therefore require the material bag on the material feeding platform wholely to move back and forth.Concrete control action is in the explanation of control section detailed sequence.Two kinds of schemes of a large platform that can have three synthetic large platforms of the chain-wales of controlling respectively and a cover to drive to this should be with definite after cost and the minimum optimization of running cost relatively.
The row collator
The task of row collator is to cooperate with the material feeding platform, co-operating accomplish with the 1 meter wide 3 meters long big square formation material bag of each row material bag from platform separately, and will wrap with parlor also front and back and separate the distance more than 0.7 meter, deliver to and highly put in order and queue machine.
Reality, the collator of structurally going is the start-up portion of the rod conveyer belt of highly arrangement and queue machine, and the drive different with velocity of downstream of oneself just arranged.The row collator is intermittent duty, after position sensor detects delegation's material and all sees this scope off, and the stall of row collator; Start material feeding platform main story simultaneously; A platform material bag that rises is moved forward, after previous row material bag shifts out platform driving scope, adopt the back bag to push away before bag mode with its shift onto two be rolled in the middle of; Stop to travel forward of platform and change motion backward into by limit switch, after making next line material guarantee for returns trip collator roller-way, stop transport.And by next line straw bag position signalling and the capable collator of platform stoppage in transit signal enabling, till straw bag is all seen off, the action before repeating.
Queue machine in up collator of frame for movement and downstream is seamless link, but the speed of row arrangement is lower than queue machine speed.When each bag shift out in the process of capable collator since before and after both sides' the speed difference two bags leave distance, this distance should be controlled at more than 0.7 meter, adopts the obstacle method of toppling over to regulate material for downstream and wraps the attitude height and create conditions.
The speed of queue machine left and right sides slideway also is different, be the power that the material bag turns to formation, but two parts slideway on the row collator can adopt constant speed, to simplify driving mechanism.
Highly put in order and queue machine
Be expert at downstream of collator of arrangement and queue machine highly, the two frame for movement is identical, drive each one, the method for operation is different, highly arrangement is to move continuously with queue machine.Be provided with one side in the direction of advance left side of queue machine and expect to protect the close smooth enclosure wall of minimum constructive height, rise near queue machine outlet somewhere, the latter half of enclosure wall is furnished with the proal belt feeder of vertical direction.Order gets into to such an extent that material bag queuing is to lean on two to intersect and make the material movement direction not only near the left side wallboard, because the speed of two roller-ways that a join left side is slow right fast, the material bag between two roller-way slits is rotated counterclockwise, thereby has changed the attitude of material bag.Should control two roller table speed differences just in time makes the material bag turn over 90 degree with the distance that the material bag walks to by wall.For not making the material bag that leans on the wall motion continue to rotate to undesirable direction, the belt team of metope bottom leans on the material bag of having put in order of wall motion to apply the power of motion forwards, and sees it off queue machine jointly with the roller-way driving force again.
Belt feeder is connected side with queue machine diameter of cylinder is bigger, and the most last roller of queue machine outlet should design is right after belt feeder cylinder top absolute altitude, so that the material bag is steadily tided over.Queue machine output material bag overlook center line should with the central lines of the Belt Length direction of belt feeder, occupy belt central authorities when making material wrap on the belt motion.
The spacing of two bags makes the terminal plough glassware operate as normal of belt feeder before and after being on the adjustment belt, the rotating-speed tracking belt feeder rotating speed of the master roller (perforation person) of queue machine, and form certain difference, make material wrap behind the belt feeder before and after about 1 meter of two bag distance.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and replacement, these improvement and replacement also should be regarded as the protection domain of the utility model.
