Description

Technical Field

[0001] The utility model relates to the technical field of fruit packaging, in particular to a fruit returning mechanism used in a fruit packaging machine. Background Art

[0002] The existing kiwi packaging machine mainly includes a chain conveyor and a suction cup manipulator. The chain conveyor is provided with a plurality of joint roller rows. Two adjacent joint rollers in the same joint roller row can support one kiwi. The kiwi is put into the input end of the chain conveyor and neatly distributed. Then, it is transported to the bottom of the suction cup manipulator. The suction cup manipulator moves several kiwis to the tray groove of the packaging box to complete the first loading of the kiwi. However, before the chain conveyor delivers the kiwi to the position of the suction cup manipulator, there is no kiwi between two adjacent joint rollers, that is, an empty space, resulting in the inconsistency between the number of kiwis sucked by the suction cup manipulator and the number of tray grooves, and the kiwis in the packaging box need to be manually filled.

[0003] Therefore, it is urgent to design a fruit return mechanism that can fill the empty space to ensure that the number of kiwi fruit packages matches the number of corresponding tray grooves. Utility Model Content

[0004] The purpose of the utility model is to overcome the defects and shortcomings in the prior art. To this end, the utility model provides a fruit returning mechanism for a fruit packaging machine, which can return fruits and fill empty spaces before the suction cup manipulator operates to ensure that the number of kiwis is consistent with the number of tray grooves.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a fruit return mechanism for a fruit packaging machine, comprising a bracket, a liftable baffle is provided below the bracket, and a plurality of photoelectric sensors installed on the bracket and used for detecting fruits are provided in front of the baffle; the baffle is configured to block the fruit and fill the empty space with the fruit when the photoelectric sensor detects an empty space for the fruit.

[0006] Furthermore, a limiting plate for preventing fruit from piling up is provided in front of the baffle.

[0007] Furthermore, two cylinders for driving the baffle to rise and fall are symmetrically arranged on the top of the bracket.

[0008] Furthermore, the cylinder body of the cylinder is hinged to the bracket, the push rod of the cylinder is hinged to the connecting plate, support rods are vertically fixed at both ends of the front side of the connecting plate, and the support rods are hinged to the bracket at one end away from the connecting plate; the baffle is fixed on the connecting plate.

[0009] Furthermore, the baffle includes a fixing plate and a rubber layer coated on the fixing plate; a pressure strip is provided on the outer side of the top of the baffle and is integrally bolted to the connecting plate.

[0010] Compared with the prior art, the utility model has the following beneficial effects: a photoelectric sensor is used to detect whether there is an empty space for fruit and control the lifting and lowering of the baffle; through the cooperation of the baffle and / or the limit plate, the fruit can be replenished to the corresponding empty space of the chain conveyor, ensuring that the number of fruits sucked by the suction cup manipulator is not missed, that is, it is consistent with the number of tray grooves in the packaging box.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention. Example

[0017] See also Figures 1 to 3 The utility model provides a fruit return mechanism for a fruit packaging machine, which includes a bracket 1, a liftable baffle 2 is provided below the bracket 1, and a plurality of photoelectric sensors 5 installed on the bracket 1 and used for detecting fruits are provided in front of the baffle 2.

[0018] Specifically, two cylinders 4 for driving the baffle 2 to move up and down are symmetrically arranged on the top of the bracket 1 .

[0019] The cylinder body of the cylinder 4 here is hinged to the bracket 1, and the push rod of the cylinder 4 is hinged to the connecting plate 6. Support rods 7 are vertically fixed at both ends of the front side of the connecting plate 6, and the support rods 7 are hinged to the bracket 1 at one end away from the connecting plate 6; the baffle 2 is fixed on the connecting plate 6 to further improve the stability of the baffle 2 in lifting and lowering.

[0020] As an embodiment of the utility model, a limiting plate 3 for preventing fruit from piling up is provided in front of the baffle 2, so that the fruit can move in a wave-like manner under the limiting plate 3. The limiting plate 3 here is fixed to the brackets on both sides of the chain conveyor, and the details are not repeated.

[0021] As an embodiment of the present utility model, the baffle plate 2 includes a fixing plate and a rubber layer covering the fixing plate; a pressure strip is provided on the outer side of the top of the baffle plate 2 and is integrally bolted to the connecting plate 6 .

[0022] like Figure 3 As shown, when the photoelectric sensor 5 detects that there is an empty space for fruit, the chain conveyor stops conveying, and the cylinder 4 drives the baffle 2 to descend and block the kiwi fruit. Then, under the action of the chain conveyor, the baffle 2 can block a row of kiwi fruit and make the kiwi fruit move in a wave-like manner under the limit plate to fill the empty space, thereby achieving the purpose of returning the fruit. Finally, the corresponding rows of fruit are transported to the bottom of the suction cup manipulator for subsequent packaging operations. The whole process can ensure that the suction cup manipulator can completely absorb the corresponding number of fruits, and it is stable and reliable.

[0023] In addition, the utility model is also applicable to small nearly round fruits such as mangosteen and orange, and the details are not repeated here.

[0024] The utility model can be summarized in other specific forms that do not violate the spirit or main features of the utility model. Therefore, no matter from which point of view, the above embodiments of the utility model can only be regarded as an explanation of the utility model and cannot limit the utility model.
