Description

Technical Field

[0001] This utility model relates to the field of fruit defective product sorting equipment, and more specifically, to a defective product sorting device for fruit processing. Background Technology

[0002] Fruits are juicy, edible plant fruits with a predominantly sweet and sour taste. Fruits are rich in vitamins and dietary fiber, which can promote digestion.

[0003] Currently, fruit production and processing involves processes such as washing, sorting, and removing substandard fruit. The process of removing substandard fruit requires workers to visually inspect and select the substandard fruit, which requires a large amount of manpower. Furthermore, manual selection can easily miss substandard fruit, resulting in generally low efficiency in the process. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a defective product sorting device for fruit processing.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A defective product sorting device for fruit processing includes an image detection device and an infrared detection device, as well as a chain conveyor, a storage box, a detection chamber, a rotating assembly, a mounting plate, an electric push rod, a mounting block, spikes, an unloading assembly, and a PU conveyor belt.

[0007] Several storage boxes with a circular main body are spaced apart on the conveyor chain of the chain conveyor, and the inside of the storage boxes is wider at the top and narrower at the bottom;

[0008] The testing chamber is mounted on a chain conveyor and is equipped with image detection devices and infrared detection devices distributed at the front and rear.

[0009] The rotating components are mounted on the chain conveyor and distributed in front of and behind the testing chamber;

[0010] The mounting plate is connected to a rotating assembly and has an electric push rod positioned directly above one of the storage boxes.

[0011] The mounting block is connected to an electric push rod and has spikes on it.

[0012] The unloading assembly is mounted on the mounting block and engages with the spikes;

[0013] The PU conveyor belt is located on one side of the chain conveyor.

[0014] Furthermore, the rotating assembly includes a drive box and a connecting roller. The drive box is provided on one side baffle of the chain conveyor. The drive box contains a drive assembly and the drive assembly is connected to the connecting roller. One end of the connecting roller is connected to a mounting plate.

[0015] Furthermore, the drive assembly employs gear transmission.

[0016] The above solution uses a rotating component to drive the secondary fruit to move above the PU conveyor belt after the spikes pierce it, and then transfers and removes the secondary fruit.

[0017] Furthermore, the unloading assembly includes a cylinder and an unloading ring. Cylinders are symmetrically arranged on the mounting block, and the cylinders are connected to the unloading rings with spikes passing through the central hole of the unloading rings.

[0018] The above solution can automatically separate the fruit from the thorns through the unloading component.

[0019] Furthermore, each of the storage boxes is equipped with an infrared transmitter, and an infrared receiver is provided on the mounting plate, which is distributed and electrically connected to the infrared transmitter.

[0020] The above solution can accurately start and stop the chain conveyor by using an infrared transmitter and an infrared receiver, thus making the movement position of the storage box more accurate.

[0021] Furthermore, a rubber layer is provided on the inner wall of the storage box.

[0022] The above solution uses a rubber layer to allow the fruit to make flexible contact with the storage box during placement, thereby reducing wear on the fruit surface. At the same time, it avoids direct hard contact between sharp points and the inner wall of the storage box, extending the service life of the device.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] Compared to existing technologies, this device can automatically transport fruits to complete quality inspection, and fruits that fail the inspection can be automatically transferred and removed. It does not require a lot of manual assistance for selection, reducing labor intensity and significantly reducing the probability of selection oversights. The process of selecting substandard fruits is optimized and the degree of automation is improved. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0031] like Figures 1 to 3 As shown, a defective product sorting device for fruit processing includes an image detection device and an infrared detection device, as well as a chain conveyor 1, a storage box 11, a detection chamber 12, a rotating assembly, a mounting plate 15, an electric push rod 16, a mounting block 17, spikes 18, a discharge assembly, and a PU conveyor belt 3.

[0032] Several storage boxes 11 with a circular main body are spaced apart on the conveyor chain of the chain conveyor 1, and the interior of the storage box 11 is wider at the top and narrower at the bottom (that is, there is an empty chain plate between the chain plates installed on two adjacent storage boxes 11).

[0033] The detection chamber 12 is mounted on the chain conveyor 1 and is equipped with image detection devices and infrared detection devices distributed at the front and back (it should be noted that the detection chamber 12 has an entrance and an exit at the front and back respectively, which are not shown in the figure).

[0034] The rotating components are mounted on the chain conveyor 1 and distributed in front of and behind the detection chamber 12;

[0035] Mounting plate 15 is connected to a rotating assembly and has an electric push rod 16 located directly above one of the storage boxes 11;

[0036] Mounting block 17 is connected to electric push rod 16 and has spikes 18 on it;

[0037] The unloading assembly is mounted on the mounting block 17 and mates with the spike 18;

[0038] The PU conveyor belt 3 is set on one side of the chain conveyor 1.

[0039] Further refinements of the embodiments of this utility model, such as... Figure 1 and Figure 2 As shown, the rotating assembly includes a drive box 13 and a connecting roller 14. The drive box 13 is provided on one side baffle of the chain conveyor 1. The drive box 13 is provided with a drive assembly and the drive assembly is connected to the connecting roller 14. One end of the connecting roller 14 is connected to a mounting plate 15. It should be noted that the drive assembly adopts gear transmission. Gear transmission is prior art and is not shown in this application, and its principle is not described.

[0040] Further refinements of the embodiments of this utility model, such as... Figure 2 and Figure 3 As shown, the unloading assembly includes a cylinder 21 and an unloading ring 22. The cylinder 21 is symmetrically arranged on the mounting block 17. The cylinder 21 is connected to the unloading ring 22 and the spike 18 passes through the central hole of the unloading ring 22.

[0041] In a further refinement of the embodiment of this utility model, each storage box 11 is provided with an infrared transmitter, and an infrared receiver is provided on the mounting plate 15 that is distributed and electrically connected to the infrared transmitter. This embodiment is not shown in the figure. By cooperating with the infrared transmitter and the infrared receiver, the intermittent start and stop of the chain conveyor 1 can be accurately completed, thereby making the movement position of the storage box 11 more accurate.

[0042] It should be noted that the chain conveyor 1, drive assembly, image detection device, infrared detection device, electric push rod 16, cylinder 21, PU conveyor belt 3, infrared transmitter and infrared receiver are all electrically connected to the controller, which is not shown in the figure.

[0043] The working process of this utility model is as follows:

[0044] First, the fruit to be tested is placed in storage box 11 (one fruit is placed in one storage box 11). In this application, the fruit to be selected as defective is one of apples, pears, oranges or tangerines, and the fruit type is the same in each round of selection. After the fruit is placed in the storage box 11, the controller controls the chain conveyor 1 to move intermittently, thereby driving the storage box 11 to move. Then the storage box 11 moves to the detection chamber 12 in sequence for detection (only one storage box 11 moves into the detection chamber 12 at a time for the detection process). The image detection device and the infrared detection device have been disclosed in the proposed defective product rejection device for fruit processing in announcement number CN216369048U. They belong to the prior art and their principles will not be described.

[0045] When the inspection is completed and the fruit in the current storage box 11 is unqualified, the image detection device or infrared detection device will send a signal to the controller. Then the controller will control the chain conveyor 1 to move forward one more time so that the current storage box 11 moves directly under the electric push rod 16. Then the controller will control the electric push rod 16 to move so that the spike 18 is inserted into the fruit. The descent depth of the spike 18 is preset according to the type of fruit. For further optimization of the scheme, several protrusions can be set on the spike 18 to increase the friction and ensure that the fruit can be easily taken out of the storage box 11 after it is inserted into the fruit.

[0046] Then, the electric push rod 16 drives the spike 18 to move upward, lifting the fruit. At this time, the controller controls the rotating component to move, thereby transferring the fruit to the area above the PU conveyor belt 3. Then, the fruit is first driven down to the preset unloading height. Then, the controller controls the cylinder 21 to work, which drives the unloading ring 22 to move downward (the initial position of the unloading ring 22 is as shown in the instruction manual). Figure 3 As shown in the diagram, at this time, the spike 18 can move along the center hole of the unloading ring 22, and the unloading ring 22 can push the fruit down. Then the fruit can be removed from the spike 18 and fall onto the PU conveyor belt 3, and then move along the PU conveyor belt 3 to be removed.

[0047] Repeating the above process can automatically remove defective fruits. Meanwhile, qualified fruits move with the chain conveyor belt and can eventually be automatically removed from the storage box 11 for collection. The fruit conveying and defective fruit selection and removal process is accurately controlled and no selection omissions occur. The labor intensity is significantly reduced compared to manual selection and removal.

[0048] Compared to existing technologies, this device can automatically transport fruits to complete quality inspection, and fruits that fail the inspection can be automatically transferred and removed. It does not require a lot of manual assistance for selection, reducing labor intensity and significantly reducing the probability of selection oversights. The process of selecting substandard fruits is optimized and the degree of automation is improved.

[0049] In some embodiments, a rubber layer is provided on the inner wall of the storage box 11, which is not shown in the figure. In this embodiment, the rubber layer can make flexible contact with the storage box 11 during the placement of fruit, thereby reducing the wear on the surface of the fruit. At the same time, it can avoid direct hard contact between the spikes 18 and the inner wall of the storage box 11, thus extending the service life of the device.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
