Description

Technical Field

[0001] The utility model relates to the field of fruit sorting, in particular to a circulating flow conveying line for fruit tray sorting. Background Art

[0002] Patent application number "202011344249.6," titled "A Ring-Shaped Weighing and Sorting Device and Method for Fruit," is a previous application from our company. Existing fruit sorting typically involves lifting and loading the fruit, then transferring it to a hopper, where it is weighed and sorted as the hopper moves forward along a chain. During the loading and sorting process, the fruit is subject to impact. This method is prone to damage for fruits like peaches, pears, and apples, making it unsuitable for sorting and boxing spherical fruits with delicate skin. Therefore, protective fruit trays are required for lifting and conveying.

[0003] The fruit trays carrying the fruits need to be sorted and then packed, and the fruit trays are circulated and transported. The existing circulation conveyor lines are generally ring-shaped and are not suitable for direct application in this production. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a circular flow conveying line for sorting fruit trays, which can realize circular conveying of fruit trays without causing congestion during the process of fruit weighing, sorting and packing.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A circular flow conveyor line for sorting fruit trays comprises a feeding conveyor belt, the feeding conveyor belt being connected in sequence with a weighing conveyor belt, a sorting and selecting conveyor belt, a first lifting conveyor belt, a return conveyor belt and a second lifting conveyor belt in a conveying direction, and an output end of the second lifting conveyor belt being connected with an input end of the feeding conveyor belt;

[0007] One side of the sorting and material conveyor belt is connected with multiple groups of first roller conveyor lines at intervals along the length direction, each group of first roller conveyor lines is connected to a group of box conveyor belts, and the output ends of multiple groups of box conveyor belts are transitionally connected to one side of the segmented return conveyor belt. A second roller conveyor line is provided on one side of the segmented return conveyor belt, adjacent to each group of box conveyor belts, and the other end of the second roller conveyor line is inclined downward and transitionally connected to one side of the return conveyor belt.

[0008] A limiting baffle is provided on the segmented return conveyor belt at one side of the second roller conveyor line.

[0009] The utility model provides a fruit tray sorting and selection circulating flow conveyor line, which has the following technical effects:

[0010] 1) Two conveyor lines are set up at the sorting and material-selecting conveyor belt. One conveys the sorted fruits that meet the weighing specifications to the packing area for packing. The empty fruit trays after packing pass through the segmented return conveyor belt and fall onto the return conveyor belt through the second roller conveyor line; the other conveys those that do not meet the weighing specifications and continues to move forward, passing through the first lifting conveyor belt and falling onto the return conveyor belt. The fruit trays are gathered on the return conveyor belt and then passed through the second lifting conveyor belt back to the loading conveyor belt in the fruit loading area, thus completing the circular transportation of the fruit trays. In addition, weighing, sorting and packing equipment can be effectively installed during the transportation process, and the structure is compact and does not occupy too much area.

[0011] 2) The first roller conveyor line and the packing conveyor belt in this application can be set up in multiple groups according to the sorting level, which is flexible to choose and has no restrictions.

[0012] 3) By setting a limit baffle, the fruit trays after sorting and boxing can be diverted to the return conveyor belt to avoid local congestion. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] like Figure 1-4As shown, a circular flow conveyor line for sorting fruit trays includes a loading conveyor belt 1. The output end of the loading conveyor belt 1 is connected to the input end of a weighing conveyor belt 2, which in turn is connected to the input end of a sorting conveyor belt 3. The output end of the sorting conveyor belt 3 is connected to the input end of a first lifting conveyor belt 4, which in turn is connected to the input end of a return conveyor belt 5. The output end of the return conveyor belt 5 is connected to the input end of a second lifting conveyor belt 6, which in turn is connected to the input end of the loading conveyor belt 1. This constitutes a first circular conveyor line.

[0021] On the basis of the first circulating conveyor line, the side of the sorting and selecting conveyor belt 3 close to the return conveyor belt 5 is transitionally connected to multiple groups of first roller conveyor lines 7 along the length direction. The other side of each group of first roller conveyor lines 7 is connected to the input end of the packing conveyor belt 8. The output ends of multiple groups of packing conveyor belts 8 are located on one side of the segmented return conveyor belt 9. On one side of the segmented return conveyor belt 9, a second roller conveyor line 10 is set adjacent to each group of packing conveyor belts 8. The other end of the second roller conveyor line 10 is tilted downward and transitionally connected to the side of the return conveyor belt 5. This constitutes the second circulating conveyor line.

[0022] Preferably, a stopper plate 9.1 is provided on the segmented return conveyor belt 9 on one side of the second roller conveyor line 10. This stopper plate 9.1 allows the empty fruit trays 11 from various locations after sorting to reach the corresponding second roller conveyor line 10 and then fall off. This allows the empty fruit trays 11 to be diverted to the return conveyor belt 5, avoiding local congestion that could affect normal production.

[0023] Working principle and process:

[0024] like Figure 5 As shown in the figure, a represents the fruit loading area, b represents the internal quality inspection area, c represents the weighing area, d represents the sorting area, e represents the packing area, and f represents the reflow area.

[0025] The quality inspection equipment and weighing equipment in this device can be both set up on the production line or set up separately, depending on production needs.

[0026] 1) During production, the fruit tray 11 is conveyed forward on the device. When passing the feeding conveyor belt 1, that is, at the fruit loading area at a, the fruit is manually placed on the fruit tray 11, one fruit tray 11 corresponding to one fruit. The fruit tray 11 carrying the fruit is conveyed forward.

[0027] 2) When passing the weighing conveyor belt 2, it arrives at the weighing area at c, completes weighing, and is then transported to the sorting and material conveyor belt 3.

[0028] 3) When passing through the sorting and shifting conveyor belt 3, that is, arriving at the sorting area at d, on the one hand, the fruit trays 11 that meet the weighing range are shifted by the fruit shifting mechanism to the first roller conveyor line 7; while the empty fruit trays 11 or the fruit trays 11 that do not meet the weighing range (the fruit is too big or too small) continue to move forward and arrive at the first lifting conveyor belt 4.

[0029] 4) When the fruit trays 11 carrying the fruit on the first roller conveyor line 7 are transported to the end of the boxing conveyor 8, the fruit is manually removed and boxed. The empty fruit trays 11 after the fruit is removed are transported to the segmented return conveyor 9, and then to the return conveyor 5 via the second roller conveyor line 10.

[0030] 5) The fruit trays 11 that have reached the first lifting conveyor belt 4 descend and move to the return conveyor belt 5.

[0031] 6) The fruit trays 11 at the return conveyor belt 5 pass through the second lifting conveyor belt 6 and enter the feeding conveyor belt 1 again, where the fruits are manually placed, or the returned fruits that do not meet the weighing range or have quality problems are removed and then placed.
