[0023] The utility model is further described below in conjunction with the accompanying drawings.

[0024] Example 1

[0025] like Figure 1 As shown, a fixed-point weighing sorting machine track, used for a tilting-plate ring sorting machine, includes a base 1, a main track 2 and a weighing module. The weighing module includes a weighing track 3, a weighing component 4 and a gap adjustment component 5. The main track 2 is fixed on the base 1; the main track 2 is an annular structure in the horizontal plane, and a partition section is provided on one of the straight sections. The partition section forms two butt ends on the main track 2 that face each other.

[0026] The weighing assembly 4 is mounted on the base 1. The weighing track 3 is mounted on the weighing assembly 4; the weighing assembly 4 is used to weigh the weighing track 3 and the sorting trolley 5 above it. The longitudinal section shape of the weighing track 3 is the same as the longitudinal section shape of the main track 2. The weighing track 3 is located in the partition section, and the two ends are aligned with the two docking ends on the main track 2 and are close to each other. The gap size between the end of the weighing track 3 and the docking end on the main track 2 is adjusted by the gap adjustment assembly 5.

[0027] like Figure 4 As shown, the length L of the weighing track 3 satisfies the following relationship: L w <L<P;L w is the axis center distance between the front and rear support wheels of the sorting trolley 5; P is the pitch of the sorting trolley 5 in the sorting machine. This ensures that all support wheels on the sorting trolley 5 can be supported by the weighing track 3 at the same time, and ensures that there is a moment when only one sorting trolley 5 is supported on the weighing track 3; specifically, the LL after the rear support wheel of a sorting trolley 5 reaches the weighing track 3 w During the trip, only one sorting trolley 5 is fully supported on the weighing track 3. Testing at this time can prevent the supporting wheels of two adjacent sorting trolleys 5 from being on the weighing track 3 at the same time, which affects the weighing accuracy.

[0028] like Figure 2 and 3 As shown, the weighing assembly 4 includes a support plate 4-1 and four weighing sensors 4-2. The support plate 4-1 is fixed on the top of the base 1. The fixed ends of the four weighing sensors 4-2 are respectively installed on the four corners of the top surface of the support plate 4-1. The height of the weighing sensor 4-2 and the weighing track 3 can be adjusted by replacing pads of different thicknesses between the weighing sensor 4-2 and the support plate 4-1; the four corners of the bottom surface of the weighing track 3 are respectively supported on the detection ends of the four weighing sensors 4-2. According to the output signals of the four weighing sensors 4-2, the weight of the weighing track 3 and the sorting trolley 5 above it is obtained.

[0029] In some embodiments, the connection structure between the weighing sensor 4-2 and the weighing track 3 is as follows: a connecting frame is fixed to the bottom of the weighing track 3. A connecting hole is provided on the connecting frame. A vertical screw structure is provided at the weighing end of the weighing sensor 4-2. The screw structure passes through the connecting hole on the connecting frame and is locked and fixed to the connecting frame by a nut.

[0030] like Figure 2 As shown, the two gap adjustment components 5 are both mounted on the base 1 and are respectively located on both sides of the weighing track 3. The gap adjustment component 5 includes two mounting brackets 5-1, two connecting pieces 5-2, and one or more adjusting screws 5-3. The two mounting brackets 5-1 are both fixed on the base 1. The two connecting pieces 5-2 are respectively fixed to the two butt ends on the main track 2. The bottoms of the two connecting pieces 5-2 are respectively slidably connected to the tops of the two mounting brackets 5-1. The connecting piece 5-2 can slide along the length direction of the weighing track 3, so that the spacing between the two connecting pieces 5-2 can be adjusted.

[0031] The specific connection structure between the connecting piece 5-2 and the mounting bracket 5-1 is as follows: a slot is provided at the top of the mounting bracket 5-1. The width direction of the slot is parallel to the length direction of the weighing track 3; a guide rod is installed in the slot; the two ends of the guide rod are respectively fixed to the two opposite side walls of the slot. The guide hole at the bottom of the connecting piece 5-2 is slidably connected to the guide rod. The width of the slot is greater than the thickness of the connecting piece 5-2.

[0032] The connecting piece 5-2 is provided with adjustment holes equal in number to and corresponding to the adjustment screws 5-3. The adjustment screws 5-3 pass through the corresponding adjustment holes on the two connecting pieces 5-2. Two adjustment nuts 5-4 are screwed onto the adjustment screws 5-3. The two adjustment nuts 5-4 are respectively located on opposite sides of the two connecting pieces 5-2. By rotating the two adjustment nuts 5-4, the distance between the two adjustment nuts 5-4 can be adjusted, so that the two connecting pieces 5-2 drive the two butt ends of the main rail 2 to move closer to or away from each other, so as to adjust the gap size between the weighing rail 3 and the main rail 2, so that the sorting trolley 5 can pass through the gap smoothly.

[0033] The relative movement of the two butt ends of the main body rail 2 is provided by the overall deformation of the main body rail 2 and / or the adjustment margin of the connection between different parts of the main body rail 2 and the base 1.

[0034] In some embodiments, a locking nut (not shown) is also installed on the adjusting screw 5-3. The locking nut can abut against the adjusting nut 5-4 or the connecting piece 5-2, so that the locking nut locks the relative position of the adjusting nut 5-4 and the connecting piece 5-2 in the form of a top nut structure.

[0035] The working principle of the utility model is as follows:

[0036] Before sorting, the gap between the main rail 2 and the weighing rail 3 is adjusted by two gap adjustment components 5; if necessary, the height of each weighing sensor 4-2 is adjusted to improve the smoothness of the sorting trolley 5 when passing through the joint between the main rail 2 and the weighing rail 3.

[0037] During the sorting operation, every time a sorting trolley 5 passes through the weighing track 3, the weighing sensor 4-2 can output the total weight of the weighing track 3, the sorting trolley 5, and the goods carried on the sorting trolley 5; the weight of the goods can be obtained by subtracting the sum of the weights of the weighing track 3 and the sorting trolley 5 from the total weight.

[0038] Example 2

[0039] A fixed-point weighing sorting machine track, the difference between this embodiment and embodiment 1 is that the weighing module also includes two in-place detection sensors. The detection part spacing of the two in-place detection sensors is equal to LL wEach sorting trolley 5 is provided with a contact piece corresponding to the in-place detection sensor.

[0040] The relative positions of the contact piece and the rear supporting wheel of the sorting trolley 5 in the horizontal direction are consistent with the relative positions of the in-place detection sensor and the output end edge of the weighing track 3 in the horizontal direction.

[0041] This achieves the following results:

[0042] When the contact piece triggers the first in-place detection sensor, the rear support wheel of the sorting trolley 5 corresponding to the contact piece just reaches the edge of the input end of the weighing track 3.

[0043] When the contact piece triggers the second in-place detection sensor, the front supporting wheel of the sorting trolley 5 corresponding to the contact piece just reaches the edge of the output end of the weighing track 3.

[0044] The time period during which the contact piece triggers the first in-place detection sensor but does not trigger the second in-place detection sensor can be used to weigh the sorting trolley 5 .

[0045] Example 3

[0046] A fixed-point weighing sorting machine track, the difference between this embodiment and embodiment 1 is that: two weighing modules are provided, and two partition sections are provided on the main track 2. The two weighing modules are respectively arranged in the two partition sections. The two weighing modules are close to each other; during the sorting operation, the two weighing modules weigh the goods on the same sorting trolley 5 successively, and the control module compares the two sets of package weight data obtained. If the two sets of package weight data are consistent, the package is placed normally. If they are inconsistent, the package enters the abnormal port and waits for subsequent processing, so as to improve the reliability of package sorting.

[0047] In the above embodiment, the rear support wheel refers to the support wheel located at the rear of the sorting trolley 5; the rear of the sorting trolley 5 is the end of the sorting trolley 5 that is away from the running direction of the sorting trolley 5. The input end of the weighing track 3 refers to the end of the weighing track 3 that is away from the running direction of the sorting trolley 5; the output end of the weighing track 3 refers to the end of the weighing track 3 that is away from the running direction of the sorting trolley 5.
