Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to an intelligent defective product rejection device for a food production line. Background Technology

[0002] Food processing refers to the process of transforming raw ingredients into food products with specific qualities, flavors, forms, and nutritional value, and which are easier to preserve, transport, and consume, through a series of physical, chemical, or biochemical methods and techniques. In food processing, substandard products need to be removed to ensure food quality.

[0003] Chinese patent CN216369048U discloses a defective fruit removal device for fruit processing. This patent improves fruit quality by setting up a sorting device to pick out defective fruits. It uses an image detection device to detect the shape and color of the fruit, an infrared detection device to detect the inside of the fruit, an electric slide rail to drive the clamp to move left and right, and a first hydraulic press to drive the clamp to move up and down, and the clamp to pick up the defective fruit.

[0004] The aforementioned patent can only roughly sort the fruit. When the fruit is transported on the conveyor, the vibration may cause the fruit to roll or even crowd together, making it difficult for the clamps to accurately pick up the bad fruit. It may even accidentally touch the good fruit next to it and damage it. This not only affects the quality of food processing but also causes additional costs. Furthermore, the damaged fruit may also have a negative impact on the hygiene of the conveyor. Utility Model Content

[0005] The purpose of this invention is to provide an intelligent defective product rejection device for food production lines, which effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] An intelligent defective product rejection device for a food production line includes a fruit conveyor belt, a sorting conveyor belt, a defective product conveyor belt, and a clamp. The outer surface of the sorting conveyor belt is evenly distributed with partitions. A diversion mechanism is installed between the fruit conveyor belt and the sorting conveyor belt, which can transfer fruits one-to-one between adjacent partitions. An image detection device and an infrared detection device are respectively installed on both sides of the outer surface of the sorting conveyor belt. A top plate is installed between the sorting conveyor belt and the defective product conveyor belt, downstream of the image detection devices and the infrared detection devices, via the rejection mechanism. The clamp is located below the top plate, and a pair of first clamping plates are installed below the clamp.

[0008] Furthermore, the diversion mechanism includes two symmetrically arranged fixed plates, with a rotating cylinder rotatably mounted between the two fixed plates. The outer surface of the rotating cylinder has a plurality of diversion channels arranged in a circular array. Each diversion channel includes several diversion channels distributed along the axis of the rotating cylinder, and the width of the diversion channels is consistent with the spacing between two adjacent partitions. A first servo motor is mounted on the outer surface of one of the fixed plates, and the end of the output shaft of the first servo motor is connected to the rotating cylinder.

[0009] Furthermore, the rejection mechanism includes a support plate installed between the sorting conveyor belt and the defective product conveyor belt. A turntable is rotatably mounted on the upper surface of the support plate, and an electric push rod is mounted on the upper surface of the turntable. The telescopic end of the electric push rod is connected to the bottom of the top plate. A second servo motor is mounted on the lower surface of the support plate, and the end of the output shaft of the second servo motor is connected to the turntable.

[0010] Furthermore, two parallel guide rods are installed through the interior of the first clamping plate. A limit block is installed at one end of each guide rod, and a second clamping plate is installed at the other end of the two guide rods. A spring is sleeved on the outer surface of the guide rod, and the two ends of the spring abut against the first clamping plate and the second clamping plate, respectively.

[0011] Furthermore, a control panel is installed on the outer surface of the defective conveyor belt.

[0012] Furthermore, the number of clamps is multiple and even, and the multiple clamps are distributed coaxially and at equal angles below the top plate.

[0013] Furthermore, rubber pads are installed on the inner wall of the diversion trough and the outer surface of the sorting conveyor belt, and the opening edges of the diversion trough are rounded.

[0014] Furthermore, the conveying width of the fruit conveyor belt is matched with the length of the rotating drum.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] 1. This utility model uses a first servo motor to drive a rotating drum, causing the fruit conveyor belt to drop into a diversion trough. The size of the diversion trough is adjusted according to the size of the fruit to ensure that only one fruit can fall into each trough. As the drum continues to rotate, the fruit in the diversion trough can fall onto the sorting conveyor belt, and each fruit will fall separately between two adjacent partitions, achieving individual separation and conveying of the fruit. Therefore, it can ensure that the clamps can accurately pick up damaged fruit and avoid accidentally touching good fruit, thereby ensuring the quality of food processing, avoiding additional costs, and preventing the damage to the sorting conveyor belt and the defective product conveyor belt from adversely affecting their hygiene.

[0017] 2. This utility model uses a second servo motor to drive an electric push rod to rotate, so that whenever one clamp is above the sorting conveyor belt, another clamp is above the defective conveyor belt. As the electric push rod moves the clamp up and down, the clamping of defective products and the placement of defective products on the defective conveyor belt can be carried out simultaneously. Compared with the prior art, which uses an electric slide rail to move defective products back and forth between the sorting conveyor belt and the defective conveyor belt, this utility model only requires the second servo motor to drive the electric push rod to rotate a certain angle to achieve the above purpose, thereby significantly shortening the movement path of the clamps and the time consumed, and improving the efficiency of rejecting defective products.

[0026] Example 1:

[0027] Please see Figures 1-4 This utility model provides an intelligent defective product rejection device for a food production line, including a fruit conveyor belt 100, a sorting conveyor belt 101, a defective product conveyor belt 102, and a clamp 107. The outer surface of the sorting conveyor belt 101 is evenly distributed with partitions 103. A diversion mechanism 200 is provided between the fruit conveyor belt 100 and the sorting conveyor belt 101, which can transfer fruits one-to-one between two adjacent partitions 103. An image detection device 104 and an infrared detection device 105 are respectively installed on both sides of the outer surface of the sorting conveyor belt 101. A top plate 106 is installed between the sorting conveyor belt 101 and the defective product conveyor belt 102, downstream of the image detection device 104 and the infrared detection device 105, via a rejection mechanism 300. The clamp 107 is located below the top plate 106, and a pair of first clamping plates 108 are provided below the clamp 107.

[0028] Fruits are uniformly placed on the fruit conveyor belt 100 for transport. The diversion mechanism 200 transfers the fruits to the sorting conveyor belt 101, ensuring that there is only one fruit between each two adjacent partitions 103. After the fruit passes between the image detection device 104 and the infrared detection device 105, its appearance and internal structure can be inspected. After inspection, the fruit is transported to the area below the clamp 107. When a defective fruit is detected, the rejection mechanism 300 drives the clamp 107 to pick up the defective fruit and place it on the defective product conveyor belt 102, thus achieving the purpose of rejecting defective products.

[0029] It is worth noting that the structure and working principle of the image detection device 104, the infrared detection device 105, and the fixture 107 are consistent with the corresponding devices in the prior art, so they will not be described in detail here.

[0030] The diversion mechanism 200 includes two symmetrically arranged fixed plates 201, with a rotating cylinder 202 rotatably mounted between the two fixed plates 201. The outer surface of the rotating cylinder 202 has a plurality of diversion channels 203 arranged in a circular array. Each diversion channel 203 includes several diversion channels 203 distributed along the axis of the rotating cylinder 202, and the width of each diversion channel 203 is consistent with the spacing between two adjacent partition plates 103. A first servo motor 204 is mounted on the outer surface of one of the fixed plates 201, and the end of the output shaft of the first servo motor 204 is connected to the rotating cylinder 202.

[0031] The first servo motor 204 is started to drive the rotating drum 202 to rotate. The fruit conveyor belt 100 transports the fruit towards the rotating drum 202. When the fruit comes into contact with the outer surface of the rotating drum 202, it will stop due to obstruction. As the rotating drum 202 rotates, the obstructed fruit can fall into the diversion trough 203.

[0032] It is worth noting that the size of the diversion channel 203 is designed according to the type and size of the fruit to be processed, to ensure that only one fruit can fall into each diversion channel 203.

[0033] As the drum 202 continues to rotate, when the opening of the diversion trough 203 tilts downward, the fruit inside rolls down its inner wall under gravity onto the sorting conveyor belt 101. Since the width of the diversion trough 203 is consistent with the spacing between two adjacent partitions 103, each fruit can fall individually between the two adjacent partitions 103 for conveying, achieving individual separation and conveying of the fruit. This ensures that the clamp 107 can accurately pick up the damaged fruit and avoids accidentally touching the good fruit, thereby ensuring the quality of food processing, avoiding additional costs, and preventing the damage to the fruit from negatively impacting the hygiene of the sorting conveyor belt 101 and the defective product conveyor belt 102.

[0034] The rejection mechanism 300 includes a support plate 301 installed between the sorting conveyor belt 101 and the defective product conveyor belt 102. A turntable 302 is rotatably mounted on the upper surface of the support plate 301, and an electric push rod 304 is mounted on the upper surface of the turntable 302. The telescopic end of the electric push rod 304 is connected to the bottom of the top plate 106. A second servo motor 303 is mounted on the lower surface of the support plate 301, and the end of the output shaft of the second servo motor 303 is connected to the turntable 302.

[0035] When the image detection device 104 and the infrared detection device 105 detect defective products and transport them to the area below the clamp 107, the electric push rod 304 lowers the clamp 107 to pick up the defective products. Then, the electric push rod 304 rises, and the second servo motor 303 rotates it, causing the clamp 107 to pick up the defective products and place them on the surface of the defective product conveyor belt 102 for transport. Furthermore, the perpendicularity tolerance of the telescopic end of the electric push rod 304 should be controlled within ±0.05mm to ±0.1mm to ensure its service life and motion accuracy.

[0036] Since the defective fruit is directly clamped from the sorting conveyor belt 101, and the lifting height of the electric push rod 304 is consistent each time, in order to avoid the bottom of the defective fruit colliding with the defective product conveyor belt 102, the height of the defective product conveyor belt 102 should be slightly lower than that of the sorting conveyor belt 101. This ensures that when the electric push rod 304 lowers the defective fruit, there is a certain gap between the bottom of the defective fruit and the defective product conveyor belt 102. Then, the clamp 107 releases the defective fruit, causing it to fall onto the defective product conveyor belt 102.

[0037] A control panel 500 is installed on the outer surface of the defective conveyor belt 102.

[0038] The control panel 500 provides unified control of the fruit conveyor belt 100, sorting conveyor belt 101, defective product conveyor belt 102, first servo motor 204, and other devices, ensuring the orderly operation of the entire equipment. By controlling the intermittent operation of the sorting conveyor belt 101, it ensures that the fruit can accurately fall from the diversion trough 203 to between two adjacent partitions 103.

[0039] Rubber pads are provided on the inner wall of the diversion trough 203 and the outer surface of the sorting conveyor belt 101, and the opening edges of the diversion trough 203 are rounded.

[0040] The rubber pads provide a cushioning effect when the fruit falls into the diversion trough 203 and onto the sorting conveyor belt 101. The rounded corners also prevent the fruit from colliding with the edge of the opening of the diversion trough 203, thus avoiding damage to the fruit.

[0041] The conveying width of the fruit conveyor belt 100 is matched with the length of the drum 202.

[0042] When the fruit stops moving due to the obstruction of the rotating drum 202, it is prevented from falling from the sides.

[0043] Example 2, based on Example 1, optimizes some of the structures:

[0044] Please see Figure 3 and Figure 4Two parallel guide rods 400 are installed through the interior of the first clamping plate 108. A limit block 401 is installed at one end of the guide rod 400, and a second clamping plate 402 is installed at the other end of the two guide rods 400. A spring 403 is sleeved on the outer surface of the guide rod 400, and the two ends of the spring 403 abut against the first clamping plate 108 and the second clamping plate 402 respectively.

[0045] Because the fruits are of varying sizes, directly clamping them with the first clamp 108 can easily cause damage due to the clamping force. Therefore, the design of the second clamp 402 and the spring 403 provides a larger buffer space when the first clamp 108 drives the second clamp 402 to clamp the damaged fruit. The elastic force of the spring 403 applies clamping force to the damaged fruit, which can effectively prevent the damaged fruit from breaking.

[0046] Example 3: Based on Example 1, some structures are optimized:

[0047] Please see Figure 3 and Figure 4 The number of clamps 107 is multiple and even, and the multiple clamps 107 are distributed coaxially and at equal angles below the top plate 106.

[0048] This design ensures that whenever one clamp 107 is above the sorting conveyor belt 101, another clamp 107 is above the defective conveyor belt 102. As the electric push rod 304 drives the clamps to rise and fall, the clamping of defective products and the placement of defective products on the defective conveyor belt 102 can be performed simultaneously. Compared to the prior art where defective products are moved back and forth between the sorting conveyor belt 101 and the defective conveyor belt 102 via an electric slide rail, this invention only requires the second servo motor 303 to drive the electric push rod 304 to rotate at a certain angle to achieve the above purpose. This significantly shortens the movement path of the clamps 107 and the time consumed, thereby improving the efficiency of rejecting defective products.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
