Description

Technical Field

[0001] The utility model relates to weighing equipment, in particular to a one-fruit-one-tray type fruit weighing and conveying device. Background Art

[0002] Fruit sorting is a key technology in modern fruit processing. It uses weighing sensors and visual image processing technology to quickly and accurately assess fruit quality. In existing, established fruit sorting technology, a lifting mechanism arranges the fruit into rows, which are then individually placed into corresponding fruit cups. The fruit is then weighed as it passes through a weighing sensor. For detailed information, see patent application number "202011344249.6," titled "A Ring-Shaped Weighing and Sorting Device and Method for Fruit." Existing weighing and conveying methods can significantly damage the fruit. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a one-fruit-one-tray type fruit weighing and conveying device, which uses the fruit tray to place the fruit and then moves it forward for weighing, thereby reducing fruit damage during the weighing and conveying process.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A one-fruit-one-tray type fruit weighing and conveying device comprises a feeding mechanism and a weighing mechanism;

[0006] The feeding mechanism includes a feeding conveyor belt, a feeding roller frame is arranged on the outside of the feeding conveyor belt, and the fruit tray carrying the fruit is transported forward by the feeding conveyor belt;

[0007] The weighing mechanism includes a first conveyor belt, wherein the input end of the first conveyor belt is transitionally connected to the feeding conveyor belt; the output end of the first conveyor belt is transitionally connected to the second conveyor belt and the third conveyor belt in sequence; the lower end of the second conveyor belt is installed on the weighing frame through a weighing sensor.

[0008] The speeds of the first conveyor belt, the second conveyor belt, and the third conveyor belt are the same, and the speeds of the first conveyor belt, the second conveyor belt, and the third conveyor belt are greater than the speed of the loading conveyor belt.

[0009] The widths of the loading conveyor belt, the first conveyor belt, the second conveyor belt and the third conveyor belt match the outer diameter of the fruit tray.

[0010] A protective shell is provided on the outside of the weighing mechanism.

[0011] A first photoelectric switch is installed on the first connecting seat of the second conveyor belt.

[0012] The utility model provides a one-fruit-one-tray type fruit weighing and conveying device, which has the following technical effects:

[0013] 1) By setting the width of the feeding conveyor belt, the first conveyor belt, the second conveyor belt and the third conveyor belt to be consistent with the outer diameter of the fruit tray, the fruit tray is transported forward in a single row, and the fruits are placed in the fruit tray one by one manually, so that the fruits avoid colliding with each other or colliding with the equipment, thereby reducing the damage caused by impact to the fruits.

[0014] 2) By setting up three sets of conveyor belts at the weighing mechanism, the speed of the three sets of conveyor belts is kept consistent and greater than the conveyor speed of the feeding conveyor belt. In this way, the fruit trays pass through the weighing mechanism one by one, thus completing the weighing one by one, ensuring the reliability of the weighing data and providing data support for subsequent sorting.

[0015] 3) Two sets of load cells ensure stability and more accurate results. A first photoelectric switch is installed at the second conveyor belt to trigger weighing, allowing the load cells to transmit weighing information to the control system, facilitating subsequent weight sorting and zoning loading. A protective housing provides dust and wind protection, preventing wind from affecting the accuracy of the load cells. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] like Figure 1 As shown, a one-fruit-one-tray type fruit weighing and conveying device includes a feeding mechanism 1 and a weighing mechanism 2. The feeding mechanism 1 is used to place the fruits one by one into the fruit tray 3 and convey them forward, and the weighing mechanism 2 is used to weigh the fruit tray 3 carrying the fruits, which is convenient for later sorting.

[0026] like Figure 1 As shown, the loading mechanism 1 includes a loading conveyor belt 1.1, which is composed of two transverse belt conveyors and two longitudinal belt conveyors. Multiple sets of loading roller racks 1.2 are located on either side of the two longitudinal belt conveyors. These racks are used to hold unsorted fruit (in fruit baskets). The output end of the loading conveyor belt 1.1 transitions to a weighing mechanism 2.

[0027] like Figure 1 As shown, empty fruit trays 3 are passed through the feeding conveyor 1.1 in a single file, and workers place the fruit from the fruit baskets into the corresponding fruit trays 3. One fruit is placed in each fruit tray 3. The fruit trays 3 carrying the fruit are transported forward by the feeding conveyor 1.1 and enter the weighing mechanism 2 one by one.

[0028] like Figure 7 As shown, the fruit tray 3 here includes an outer frame, and multiple layers of support plates are arranged from top to bottom in the outer frame. Each layer of support plates is composed of multiple pieces of rubber support plates, which can support and limit the fruit. At the same time, due to the use of rubber material, it can also provide buffering and prevent collisions.

[0029] Among them, Figure 2-3 As shown, the weighing mechanism 2 includes a first conveyor belt 2.1, a second conveyor belt 2.2, and a third conveyor belt 2.3, which are arranged in order from front to back. The first conveyor belt 2.1, the second conveyor belt 2.2, and the third conveyor belt 2.3 are each driven by an independent first motor 2.4.

[0030] The speeds of the first, second, and third conveyor belts 2.1, 2.2, and 2.3 are the same, and are greater than the speed of the loading conveyor belt 1.1. The ratio of the speeds of the first, second, and third conveyor belts 2.1, 2.2, and 2.3 to the speed of the loading conveyor belt 1.1 can be 4 to 6:1. Because the speeds of the first, second, and third conveyor belts 2.1, 2.2, and 2.3 are much greater than the speed of the loading conveyor belt 1.1, the fruit trays 3 carrying the fruit can be weighed one by one as they pass through the first, second, and third conveyor belts 2.1, 2.2, and 2.3.

[0031] like Figure 2 As shown, first positioning plates 2.5 are installed on the left and right sides of the first and third conveyor belts 2.1 and 2.3, respectively. The spacing between the left and right first positioning plates 2.5 is consistent with the diameter of the fruit tray 3. The input ends of the left and right first positioning plates 2.5 are both open outward to provide guidance and facilitate the entry of the fruit tray 3.

[0032] like Figure 4-5 As shown, the weighing frame 2.6 below the second conveyor belt 2.2 has four sets of through holes, each corresponding to a first screw 2.7. The lower ends of the first screws 2.7 freely pass through the through holes in the weighing frame 2.6. A first nut 2.8 is threadedly connected to the first screw 2.7 at the upper end of the weighing frame 2.6, providing positional support for the first screw 2.7. A second nut 2.9 is threadedly connected to the first screw 2.7 above the first nut 2.8. The first mounting plate 2.10 has corresponding adjustment holes. The first mounting plate 2.10 passes through the adjustment holes and is supported by the second nut 2.9. The first mounting plate 2.10 is provided with two groups of weighing sensors 2.11, which are arranged at both ends of the second conveyor belt 2.2 in the length direction and on the left and right sides respectively. The upper end of each weighing sensor 2.11 is connected to the first connecting plate 2.12, and the left and right ends of the first connecting plate 2.12 are connected to the first connecting seat 2.13 of the second conveyor belt 2.2. The first connecting seat 2.13 is used to place the belt, rotating shaft, etc. of the second conveyor belt 2.2.

[0033] By providing two sets of weighing sensors 2.11, it is possible to weigh the fruit trays 3 carrying fruits passing through the second conveyor belt 2.2, and to facilitate subsequent sorting according to weight.

[0034] Preferably, first photoelectric switches 2.14 for detecting fruit trays 3 carrying fruits are provided on both sides of the upper end of the second conveyor belt 2.2.

[0035] like Figure 6As shown, preferably, the weighing mechanism 1 is provided with a protective housing 2.15 above and below. The left and right sides of the protective housing 2.15 are provided with observation windows made of transparent acrylic panels. The front and rear of the protective housing 2.15 are provided with baffles made of PU rubber, each having a through hole for the fruit tray 3 to pass through.

[0036] Working principle and process:

[0037] 1) First, the worker places the fruit basket filled with fruit on the loading roller rack 1.2, and then starts the loading conveyor 1.1 at the loading mechanism 1. The fruit trays 3 are continuously transported from the return belt (not shown) on the input side of the loading conveyor 1.1 to the loading conveyor 1.1.

[0038] 2) The fruits are placed manually one by one on the corresponding fruit trays 3, and the fruit trays 3 carrying the fruits are transported forward to the weighing mechanism 2.

[0039] 3) Since the speeds of the first conveyor belt 2.1, the second conveyor belt 2.2 and the third conveyor belt 2.3 at the weighing mechanism 2 are much greater than the speed of the feeding conveyor belt 1.1, the fruit trays 3 carrying the fruits pass through the weighing mechanism 2 one by one, and when passing through the second conveyor belt 2.2, they are weighed and quickly conveyed forward.
