On the basis of the above sorting machine goods supply table, the embodiment further provides a goods supply method, as shown in fig. 3, the goods supply method specifically includes the following steps:

s1, placing the first parcel on a first conveying mechanism of the parcel placing section 100, wherein the first parcel is conveyed at a constant speed at a first speed V1 along a first direction.

Specifically, a package is picked up from the stack of packages manually by hand or manually using an external device (e.g., a pick-and-place robot) and placed at a pick-and-place station of the pick-and-place section 100. To describe the flow of the supply method and to facilitate distinguishing between packages at different locations on the supply station, the package is designated as the first package.

Since the length of transmission of the decapping segment 100 is L1, the time T0 required for the first packet to pass through the decapping segment 100 is L1/V1. At this time, if the length L0 of the first packet itself is much smaller than the transmission length of the packet release section 100 by L1, the length L0 of the first packet itself is ignored in calculating time, and when the length L0 of the first packet itself is not negligible, T0 is (L1+ L0)/V1.

S2, the second transport mechanism of the weighing section 200 docks the first package in the first direction at a first velocity V1.

The second transmission mechanism is in butt joint with the first parcel at the same transmission speed as the first transmission mechanism, and the stability of the transition of the first parcel in the placing section 100 and the weighing section 200 is improved, so that the situation that the parcel is toppled over to cause damage to articles in the parcel and displacement of the center position is avoided.

S3, selecting a weighing mode by a weighing mechanism of the weighing section 200, and weighing the first package, wherein the time length required by weighing is T1;

after weighing is finished, the second conveying mechanism accelerates to a second speed V2, and the first package is conveyed for a time period of T2 and reaches the junction of the weighing section 200 and the upper package section 300.

Specifically, with continued reference to fig. 3, the selection of the weighing mode by the weighing mechanism of the weighing section 200 and the weighing of the first package specifically includes the following steps:

judging whether a third parcel is on the upper parcel section 300;

if yes, the second transmission mechanism decelerates to 0, and the weighing mechanism performs static weighing on the first package;

if not, the second transport mechanism continues to transport at the first speed V1 and the weighing mechanism dynamically weighs the first package.

S4, docking the first parcel with the third conveyance mechanism of the upper parcel section 300 at a second speed V2 in the first direction;

after the first parcel has been transported for a time period of T3 at the second speed V2, the third conveyance mechanism is accelerated to the third speed V3, and the first parcel arrives at the intersection of the upper package section 300 and the sortation line after being transported for a time period of T4 at the third speed V3.

According to the supply method, after weighing is finished, the second conveying mechanism is accelerated to the second speed V2 from the first speed V1, and after the third conveying mechanism is in butt joint with the packages, the second speed V2 is accelerated to the third speed V3, so that the time required by the packages to pass through the supply table is shortened, and the operation efficiency of the whole supply table is improved.

Optionally, as shown by continuing to refer to fig. 3, the step S1 specifically includes the following steps:

placing the first wrap on a first transport mechanism of the placing section 100;

judging whether a second package is on the weighing section 200;

if yes, the first transmission mechanism stops transmission;

if not, the first conveying mechanism continues to convey the first parcel in the first direction at a constant speed at a first speed V1.

The second parcel here is the parcel which is downstream of and closest to the first parcel described above.

Alternatively, the detection mechanism 400 may determine whether a second package is on the weigh segment 200. Specifically, detect the second parcel as first time point with detecting structure, first time point plus the time that the second parcel required through section 200 of weighing is the second time point, detect to put first parcel as the third time point on putting the package station with parcel detection sensor 101, regard as the fourth time point with the third time point plus the time that the first parcel passes section 100 of putting the package. Judging whether a second package exists on the weighing section 200 or not by comparing the sequence of the second time point and the fourth time point, and if the second time point is smaller than the fourth time point, determining that the weighing section 200 does not have the second package; if the second time point is greater than or equal to the fourth time point, the weighing section 200 has a second parcel.

Alternatively, the detection mechanism 400 and the high-precision encoders disposed on the driving motors of the first conveying mechanism and the second conveying mechanism may be used to determine whether the weighing section 200 has the second parcel. Specifically, the detection structure detects a second parcel as a first time point, the detection structure detects a first parcel as a second time point, the high-precision encoder is used for obtaining the distance S transmitted between the two time points by the second transmission mechanism, and if S is greater than the transmission length L2 of the weighing section 200, the weighing section 200 has no second parcel; if S is less than or equal to the conveying length L2 of the weighing section 200, there is a second package on the weighing section 200.

the detection mechanism 400 at the junction of the bale-placing segment 100 and the weighing segment 200 acquires the projected area and the center point of the first bale.

Since the end of the upper block 300 has the inclined connecting surface, the position where the parcel enters the upper block 300 is different, and the distance L3 transmitted on the upper block 300 is also different, and a specific L3 value can be calculated by obtaining the center position of the parcel using the sensing mechanism 400. And by acquiring the projected size of the parcel, it is convenient to calculate the time required for the parcel to pass through the weighing section 200 and the wrapping section 300 at a later stage.

Further, with continued reference to fig. 5, the control mechanism, while the detection mechanism 400 acquires the projected area and the center point of the first parcel, may further perform the following steps:

T0＝T1+T2+T3+T4②,T1>＝T_weighing,T2>＝0,T3>＝0,T4>0；

L2 ═ T1 ═ V1+ T2 ═ V2, V1 and L2 are all constant values;

l3 ═ V2 × T3+ V3 × T4, L3 is a fixed value, and it can be directly obtained from the position of the center point of the first parcel obtained by the detection means 400;

v3 is V0/cos (alpha), V0 and alpha are both fixed values;

by the above formula and the limitation conditions, suitable T1, T2, T3, T4 and V2 can be deduced by using mathematical software.

In the present embodiment, V0 is 2 m/s; v1 ═ 1.1 m/s; v2 ═ 1.8 m/s; v3 ═ 2.3 m/s; a is 30 °.
