The push area of break-in conveying mechanism is positioned at above the second load-transfer device 21.During work, on the first load-transfer device 20, place product; First load-transfer device 20 rotates, the second load-transfer device 21 rotates simultaneously, but the velocity of rotation of the second load-transfer device 21 is greater than the velocity of rotation of the first load-transfer device 20; Just accessed by the input end of the second load-transfer device 21 when product is output from the mouth of the first load-transfer device 20, the product that both velocity contrasts make just to enter into the second load-transfer device 21 increases suddenly with the spacing of product of the mouth being in the first load-transfer device 20, spacing between so adjacent product is widened, should reach the product spacing of setting under normal circumstances, the first load-transfer device 20, second load-transfer device 21 of differential motion forms the grouping parts on product conveyor structure.
After arrangement pitches adjustment between adjacent product, product is carried by break-in conveying mechanism position on the second load-transfer device 21.When product moves to second place sensor 18 position, second place sensor 18 detects product, simultaneously primary importance sensor 19 starts situation about detecting below it, if primary importance sensor 19 detects that product is positioned at below it, then represent that the spacing between these two adjacent product is abnormal, arrangement pitches is less than setting value, and now preceding product can not to be promoted by break-in through push area.And then, the product of original position below primary importance sensor 19 moves to the below of second place sensor 18, primary importance sensor 19 starts situation about detecting below it, if primary importance sensor 19 detects and have product to be positioned at below it, then represent that the spacing between these two adjacent product is also abnormal, arrangement pitches is less than setting value, and now preceding product can not to be promoted by break-in through push area; If primary importance sensor 19 detects and do not arrive product and be positioned at below it, then represent that the spacing of these two adjacent product is normal, arrangement pitches is more than or equal to setting value, and the product be now positioned at below second place sensor 18 is admitted to push area.
3rd conveying mechanism is driven by the 3rd servomotor 26, the 4th conveying mechanism is driven by the 4th servomotor 29.The power of the 3rd conveying mechanism, the 4th conveying mechanism is all independent power.3rd conveying mechanism, the 4th conveying mechanism synchronously move in the same way, and geo-stationary between third gear plate 24 and fourth gear plate 27, the width dimensions of such push area is constant.When the normal product of spacing is transported to push area, the 3rd conveying mechanism and the 4th conveying mechanism synchronously move in the same way, and product is promoted relative load-transfer device by fourth gear plate and laterally shifts out, in the storage space thus in product introduction cyclic permulation mechanism.
Cyclic permulation mechanism 30 is also positioned at the below of break-in conveyer 23 structure, and the storage space in cyclic permulation mechanism is relative with the push area of break-in conveying mechanism.Storage space sense of motion is identical with push area sense of motion, but both sense of motions are all vertical with the throughput direction of product conveyor structure.
Third gear plate, fourth gear plate do straight-line displacement at the straight line portion of Timing Belt, therefore push area moves on straight operating path; Meanwhile, next push area synchronously follows up, enter pause motion behind the top of the second load-transfer device, wait the second load-transfer device by product qualified for spacing input push area time servomotor again start, then product is promoted relative load-transfer device by fourth gear plate and laterally shifts out.Each push area only promotes a product at every turn.Storage space in cyclic permulation mechanism often receives a product with regard to motion certain distance, so that next storage space aims at the push area of break-in conveying mechanism.
Each product below second place sensor and the spacing in the conveying direction between the product of its rear adjacent normal, this product all can be pushed by break-in in thrust zone, the product of spacing exception can be exported by the mouth from the second load-transfer device, now cylinder shrinks, baffle plate 22 shifts out above the second load-transfer device 21, and product is discharged smoothly; Telescopic-cylinder formula makes baffle plate 22 move up and down, so baffle plate 22 could protrude on the second load-transfer device, and also can principle second load-transfer device.According to the operating mode of reality, baffle plate 22 can also be horizontal reciprocating movement, or hunting motion, plays barrier effect as long as the position relationship between guarantee baffle plate 22 and the second load-transfer device can be carried product and ensures the effect that product passes through smoothly.
Push area enters above load-transfer device continuously, and product input process and push area enter process coordinating and coordinate, and makes product in high speed course of conveying, can be laterally moved out load-transfer device fast.The distance of push area and load-transfer device is determined by product thickness, and position relationship is between the two reconciled by lifting mechanism, need when product thickness is thin push area and load-transfer device from must close to, namely third gear plate, fourth speed plate are little from the vertical distance of load-transfer device; Need when product thickness is thick push area and load-transfer device from must away from, namely third gear plate, fourth speed plate are large from the vertical distance of load-transfer device, ensure that side plate can not stop product.
Product to push another size then can adjust push area width by online mode, concrete, 3rd servomotor 26 stop motion, the 4th servomotor 29 are according to new width value outputting power, fourth gear plate 27 is followed the 4th Timing Belt 28 and is moved, 4th Timing Belt 28 can do the rotation of both forward and reverse directions under the driving of the 3rd servomotor 26, make bending part be that dislocation is changed back to the distance between the third gear plate 24 and fourth gear plate 27 of relation, this change can be that distance increases, also can be distance reduction.The width adjusting mode of push area realizes based on the distance changed between third gear plate 24 and fourth gear plate 27, so, adjustment mode can also be that the 4th servomotor 29 stop motion, the 3rd servomotor 26 are according to new width value outputting power, third gear plate 24 is followed the 3rd Timing Belt 25 and is moved, and makes bending part be that dislocation is changed back to the distance between the third gear plate 24 and fourth gear plate 27 of relation; Adjustment mode can also be that the 3rd servomotor 26 velocity of rotation is less than or is greater than the 4th servomotor 29 velocity of rotation, the kinematic velocity of third gear plate 24 on the 3rd operating path and the kinematic velocity of fourth gear plate 27 on the 4th path inconsistent, relative motion between third gear plate 24 and fourth gear plate 27, when the distance between third gear plate 24 and fourth gear plate 27 adjusts to setting value, the 3rd conveying mechanism and the 4th conveying mechanism change to from asynchronous movement and are synchronized with the movement.The width of push area is maximum is the thickness that distance between adjacent third gear plate 24 deducts fourth gear plate 27, together with now third gear plate 24 contacts with fourth gear plate 27, due to third gear plate 24, place is provided with recess, thus both contact after the bending part of fourth gear plate 27 stretch between the bending part of third gear plate 24.The width of push area is minimum is the thickness that the half of distance between adjacent third gear plate 24 deducts fourth gear plate 27, and now fourth gear plate 27 is positioned at the centre of third gear plate 24, and fourth speed plate is all equal to the distance of adjacent third gear plate 24.
Product is pushed to cyclic permulation mechanism by the baffle plate of break-in conveying mechanism at the second load-transfer device 21 on the direction of the throughput direction of vertical second load-transfer device 21, in break-in process, product reduces at the kinematic velocity of the throughput direction of the second load-transfer device 21, on the throughput direction of conveying mechanism, obtaining less kinematic velocity, product enters in the storage space of cyclic permulation mechanism with lower-speed state simultaneously.
