Description

Technical Field

[0001] The invention belongs to the technical field of food processing and relates to an orange processing device, in particular to an orange segmenting machine. Background Art

[0002] Oranges, also known as mandarins, are a type of fruit in the Rutaceae family, the genus Citrus. Canned oranges are made from peeled segments, and separating the segments is an important process.

[0003] Traditional citrus segmentation relies on manual labor, which is a typical labor-intensive process with high labor intensity, low production efficiency and uncontrolled health, safety and quality issues.

[0004] In order to solve the problems existing in traditional manual citrus peeling, the applicant has proposed an orange peeling machine (application number 201811038636.X). During operation, the peeled oranges are first placed on the orange carrying column; then the camera captures the image of the oranges loaded on the orange carrying column to obtain the position information of the orange peeling line; then the orange carrying column loaded with oranges is moved to the orange rotating position corresponding to the orange rotating mechanism, and then the guide hole of the orange rotating mechanism is moved to a fixed position corresponding to the guide column of the orange carrying column; finally, the orange rotating mechanism rotates the orange according to the peeling line position information, so that the multiple peeling lines of the orange correspond to the positions of the peeling saw in turn. When the peeling saw corresponds to the peeling line position, the peeling line of the cutting part of the peeling saw is controlled. The orange peeling machine has the following shortcomings in the production process: the orange carrying column is fixed on the conveyor plate, and the end of the orange carrying column facing away from the conveyor plate is rotatably connected to the guide rod and the orange supporting plate, and the oranges are mounted on the guide rod and supported by the orange supporting plate; if the friction resistance between the guide rod and the orange supporting plate and the orange carrying column is large, when the oranges are soft, the orange turning mechanism cannot drive the guide rod and the orange supporting plate to rotate synchronously, which causes the peeling line to be unable to align with the peeling saw, and even causes the oranges to be damaged; if the friction resistance between the guide rod and the orange supporting plate and the orange carrying column is small, the oranges will naturally rotate due to vibration and bumps during the process of being transported from the camera shooting area to the position directly below the orange turning mechanism, which causes the peeling line to be unable to align with the peeling saw; in the actual process, due to problems such as contamination and wear of components, the friction resistance between the guide rod and the orange supporting plate and the orange carrying column varies, which makes it difficult to ensure that the friction resistance between the guide rod and the orange supporting plate and the orange carrying column is always within the required range; further, the above-mentioned technical problems will affect the orange peeling qualification rate. Summary of the Invention

[0005] The present invention provides an orange segmenting machine, and the technical problem to be solved by the present invention is how to improve the orange segmenting qualification rate of the orange segmenting machine.

[0006] The technical problem to be solved by the present invention can be achieved through the following technical solutions: Solution 1: An orange sorting machine includes a frame and an orange-carrying column, a conveyor belt assembly is installed on the frame, and the conveyor belt assembly includes a supporting member that can move horizontally; one end of the orange-carrying column is a guide section for inserting oranges, and one end of the orange-carrying column is installed with an orange-supporting tray, and the other end of the orange-carrying column is rotatably connected to the supporting member; a lower orange-carrying assembly and an upper orange-carrying assembly located directly above the lower orange-carrying assembly are installed on the frame, and the upper orange-carrying assembly includes an upper pressure plate; when the supporting member drives the orange-carrying column to move, the orange-carrying column can move between the lower orange-carrying assembly and the upper orange-carrying assembly, and the orange-carrying column is in a vertical state with the guide section facing upward. In this state, the lower orange-carrying assembly can be connected to the other end of the orange-carrying column and can drive the orange-carrying column to rotate, and the upper orange-carrying assembly can connect the upper pressure plate with the oranges loaded on the guide section and can make the upper pressure plate and the orange-supporting tray rotate synchronously.

[0007] Although the orange-carrying column and the supporting member are connected in a rotational manner, the frictional resistance between the two is increased to prevent the orange-carrying column from rotating naturally when it moves with the supporting member. When the orange-carrying column is located between the lower orange-turning assembly and the upper orange-turning assembly, that is, when the orange-carrying column is at the orange-turning station, at least the lower orange-turning assembly can be used to drive the orange-carrying column to rotate, thereby driving the orange-supporting plate, the oranges, and the upper pressure plate to rotate synchronously; of course, the lower orange-turning assembly and the upper orange-turning assembly can also be used to drive the orange-supporting plate, the oranges, and the upper pressure plate to rotate synchronously. In summary, this orange-slicing machine not only fully utilizes the frictional resistance of the rotational connection between the orange-carrying column and the supporting member to prevent the oranges from rotating naturally during transportation from the camera shooting area to the orange-slicing station, but also eliminates the influence of the frictional resistance of the rotational connection between the orange-carrying column and the supporting member, allowing the oranges, the upper pressure plate, and the orange-supporting plate to rotate synchronously, thereby increasing the alignment rate between the orange-slicing line and the orange-slicing saw and reducing the orange breakage rate, thereby improving the orange-slicing qualified rate of the orange-slicing machine.

[0008] Option 2: An orange sorting machine includes a frame and an orange-carrying column, a conveyor belt assembly is installed on the frame, and the conveyor belt assembly includes a carrier that can move horizontally; one end of the orange-carrying column is a guide section for inserting oranges, and one end of the orange-carrying column is installed with an orange-supporting tray, and the other end of the orange-carrying column is rotatably connected to the carrier, and a rotation locking mechanism for limiting the rotation of the orange-carrying column is installed on the carrier, and an unlocking assembly and an upper orange-turning assembly located directly above the unlocking assembly are installed on the frame, and the upper orange-turning assembly includes an upper pressure plate; when the carrier drives the orange-carrying column to move, the orange-carrying column can move between the unlocking assembly and the upper orange-turning assembly, and the orange-carrying column is in a vertical state with the guide section facing upward. In this state, the unlocking assembly can enable the rotation locking mechanism to release the rotation restriction of the orange-carrying column, and the upper orange-turning assembly can connect the upper pressure plate with the oranges loaded on the guide section and can drive the oranges, the orange-supporting tray and the orange-carrying column to rotate synchronously.

[0009] Although the orange-carrying column and the carrier are connected in a rotational manner, a rotation locking mechanism is used to restrict the rotation of the orange-carrying column during the movement of the orange-carrying column with the carrier, thereby preventing natural rotation. When the orange-carrying column is located between the unlocking assembly and the upper orange-turning assembly, that is, when the orange-carrying column is in the orange-turning station, the unlocking assembly is first used to release the rotation restriction of the orange-carrying column by the rotation locking mechanism, and then the upper orange-turning assembly is used to drive the oranges to rotate; by reducing the frictional resistance between the orange-carrying column and the carrier, when the upper orange-turning assembly drives the oranges to rotate, it drives the orange-supporting plate and the orange-carrying column to rotate synchronously. In summary, this orange-slicing machine not only reduces the rotational frictional resistance between the orange-carrying column and the carrier, so that the oranges, the upper pressure plate and the orange-supporting plate rotate synchronously, thereby improving the alignment rate of the orange-slicing line and the slice saw and reducing the orange breakage rate, thereby improving the orange-slicing qualified rate of the orange-slicing machine; it also prevents the orange-carrying column from rotating naturally when it moves with the carrier by providing a rotation locking mechanism and an unlocking assembly.

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0025] Embodiment 1: An orange segmenting machine includes a frame 1, an orange carrying column 5, a conveyor belt assembly 2, a lower orange transfer assembly 3, an upper orange transfer assembly 4, an orange cutting assembly and an industrial camera.

[0026] like Figure 1 and Figure 2 As shown, the frame 1 includes a main frame 1a and a lifting frame 1b. The main frame 1a is typically placed on the ground. The lifting frame 1b is connected to the main frame 1a via a lifting guide assembly 1c and a lifting drive 1d. The lifting drive 1d thus enables the lifting frame 1b to move stably and flexibly. The accompanying drawings in this specification illustrate that the lifting drive 1d is a cylinder.

[0027] The conveyor belt assembly 2 includes a carrier 2a and a motor. The carrier 2a is in the shape of a strip plate. There are multiple carriers 2a, which are arranged in a ring and connected to each other. The drawings in the specification only illustrate three petal processing stations. The number of petal processing stations can be adaptively increased according to actual conditions. The carriers 2a are also shown in only three numbers. The number of orange cutting assemblies is the same as the petal processing stations and is arranged in a one-to-one correspondence. The orange cutting assemblies are installed on the main frame 1a. The carrier 2a is connected to the main frame 1a through an annular guide structure. The annular guide structure has a horizontal guide section, so that the carrier 2a can move horizontally. The motor is installed on the main frame 1a. The main shaft of the motor is connected to the carrier 2a through a transmission structure, so that the motor can drive the carrier 2a to move repeatedly along the guide direction of the above-mentioned annular guide structure.

[0028] like Figures 1 to 5 As shown, the orange-carrying column 5 is arranged perpendicularly relative to the plate surface of the supporting member 2a. One end of the orange-carrying column 5 is a guide section 5a for inserting oranges. An orange-carrying tray 8 is mounted on one end of the orange-carrying column 5. The orange-carrying tray 8 and the orange-carrying column 5 are connected by a key circumferential positioning connection, a tight fit, adhesive bonding, or a fixed connection using fasteners. The other end of the orange-carrying column 5 passes through the supporting member 2a. The orange-carrying column 5 and the supporting member 2a are rotationally connected via a first bearing 10. Here, the first bearing 10 is used to improve the rotational stability of the orange-carrying column 5, and does not need to significantly reduce the rotational friction resistance of the orange-carrying column 5. In other words, the rotational friction resistance of the first bearing 10 can limit the natural rotation of the orange-carrying column 5. When the supporting member 2a is located in the horizontal guide section of the annular guide structure, the orange-carrying column 5 is in a vertical state.

[0029] like Figures 1 to 8 As shown, the lower turntable assembly 3 and the upper turntable assembly 4 are arranged in a one-to-one correspondence, and the upper turntable assembly 4 is located directly above the lower turntable assembly 3. The number of lower turntable assemblies 3 and upper turntable assemblies 4 corresponds to the number of petal separation processing stations. The accompanying drawings in the specification show three petal separation processing stations, so only three sets of lower turntable assemblies 3 and upper turntable assemblies 4 are shown.

[0030] The lower turntable assembly 3 comprises a lower turntable driver 3a and a connecting cap 3b. The accompanying drawings illustrate lower turntable driver 3a as a motor. Lower turntable driver 3a is mounted on the lifting frame 1b, and connecting cap 3b is connected to the main shaft of lower turntable driver 3a via a lower transmission shaft 3c. The other end of the support column 5 is fixedly connected to a connecting plate 9 that fits within connecting cap 3b. Depending on the application, the mounting positions of connecting plate 9 and connecting cap 3b can be interchanged, with connecting plate 9 mounted on the lower transmission shaft 3c and connecting cap 3b mounted on the support column 5.

[0031] like Figure 1As shown, when the carrier 2a drives the orange-carrying column 5 to move horizontally above the lower turntable assembly 3, the lifting drive 1d drives the lifting frame 1b to move upward, so that the connecting plate 9 and the connecting cap 3b can contact each other. The cooperation between the connecting plate 9 and the connecting cap 3b generates a large friction force, and then the lower turntable drive 3a drives the orange-carrying column 5 to rotate through the lower transmission shaft 3c, the connecting plate 9 and the connecting cap 3b. Figure 9 As shown, the lifting drive member 1d drives the lifting frame 1b to move downward to separate the connecting plate 9 and the connecting cap 3b, thereby preventing the lower rotating orange assembly 3 from interfering with the supporting member 2a to drive the orange column 5 to move.

[0032] like Figures 4 to 8 As shown, the lower transmission shaft 3c comprises a lower transmission section 3c1 and an upper transmission section 3c2 sleeved thereon. The lower and upper transmission sections 3c1 and 3c2 are connected by a circumferential positioning structure, enabling axial movement between the upper and lower transmission sections 3c2 and 3c1, but preventing circumferential rotation. The lower transmission shaft 3c also includes a first elastic member 3c3, which ensures constant axial movement between the upper and lower transmission sections 3c2 and 3c1 and contributes to the axial extension of the lower transmission shaft 3c. When the lifting drive 1d drives the lifting frame 1b upward, not only does it cause the connecting plate 9 and the connecting cap 3b to contact, but it also compresses the first elastic member 3c3, significantly reducing the control accuracy of the lifting drive 1d's travel, ensuring that the abutment force between the connecting plate 9 and the connecting cap 3b remains essentially constant. This prevents the lower turntable assembly 3 from dislodging components such as the carrier 2a and the turntable column from their set positions. The connection structure between the upper transmission section 3c2 and the lower transmission section 3c1; more specifically, a strip-shaped limit groove 3c4 is provided on the lower transmission section 3c1, and the upper transmission section 3c2 is fixedly connected with a limit pin 3c5 embedded in the limit groove 3c4. The first elastic member 3c3 is sleeved on the lower transmission section 3c1, and the first elastic member 3c3 is in contact with the lower end surface of the upper transmission section 3c2.

[0033] The lower end of the lower transmission shaft 3c is connected to the main shaft of the lower rotary drive member 3a via a coupling 3d. Specifically, the lower end of the transmission lower section 3c1 is connected to the coupling 3d, the lower end of the first elastic member 3c3 abuts against the coupling 3d, and the connecting cap 3b is fixedly connected to the top of the transmission upper section 3c2. This structure also enables transmission when the axis of the lower transmission shaft 3c is offset from the axis of the main shaft of the lower rotary drive member 3a. In other words, in this state, the lower transmission shaft 3c is tilted. In other words, this structure reduces the accuracy of the position of the support member 2a and the support column 5.

[0034] The connecting cap 3b has radially extending connecting spokes 3b1. The connecting cap 3b is made of an elastic material, as is the connecting disc 9. When the axis of the carrier column 5 deviates from the main axis of the lower rotary drive member 3a, the connecting spokes 3b1 of the connecting cap 3b are always in close contact with the side areas of the connecting disc 9, and are partially deformed, thereby improving the transmission efficiency and stability between the connecting disc 9 and the connecting cap 3b.

[0035] The upper transmission section 3c2 secures the conical block 3e, which is fitted with a conical positioning ring 3f, secured to the lifting frame 1b. When the lower orange transfer assembly 3 is separated from the orange column 5, the upper transmission section 3c2, under the elastic force of the first elastic member 3c3, forces the conical block 3e against the side of the tapered inner hole of the tapered positioning ring 3f, effectively positioning the lower transmission shaft 3c. This ensures consistent positioning of the lower transmission shaft 3c when the orange sorting machine is in this state, increasing the success rate of successful docking between the connecting plate 9 and the connecting cap 3b. When the lifting drive member 1d drives the lifting frame 1b upward and the first elastic member 3c3 is compressed, the conical block 3e separates from the side of the tapered inner hole in the tapered positioning ring 3f, ensuring that the lower transmission shaft 3c can swing freely. The top of the lower transmission shaft 3c is conical, and a pre-positioning hole 9a is provided at the center of the bottom surface of the connecting disk 9. When the lifting drive member 1d drives the lifting frame 1b to move upward, the top of the lower transmission shaft 3c is first embedded in the pre-positioning hole 9a to achieve pre-positioning, and then the connecting disk 9 contacts the connecting cap 3b. This structure further improves the success rate of effective docking between the connecting disk 9 and the connecting cap 3b each time.

[0036] The upper turntable assembly 4 includes an upper platen 4a and an upper turntable driver 4b. The accompanying drawings illustrate the upper turntable driver 4b as a motor. The main shafts of the upper platen 4a and upper turntable driver 4b are connected via an upper transmission shaft 4c. The upper transmission shaft 4c of the upper turntable assembly 4 is connected to the frame 1 via a guide structure and a platen lift cylinder. The connecting structure between the upper turntable driver 4b and the frame 1 is not shown in the accompanying drawings.

[0037] By explaining the use process of the orange peeling machine, the functions and advantages of each component are further explained. The industrial camera, conveyor belt assembly 2, lower orange transfer assembly 3, upper orange transfer assembly 4 and orange cutting assembly are all electrically connected to the control circuit.

[0038] The peeled oranges are called orange balls 100. The orange balls 100 are first inserted into the guide section 5a of the orange-carrying column 5, and the orange-carrying plate 8 holds the orange balls 100; the conveyor belt assembly 2 drives the orange-carrying column 5 and the orange balls 100 to move horizontally to the bottom of the industrial camera, and under the illumination of the fill light, the industrial camera takes a photo of the top surface of the orange balls 100.

[0039] The conveyor belt assembly 2 continues to drive the orange column 5 and the orange meat ball 100 to move horizontally between the lower orange transfer assembly 3 and the upper orange transfer assembly 4. In this process, the rotational friction resistance of the first bearing 10 ensures that the orange column 5 is restricted from rotating naturally.

[0040] The control circuit then controls the pressure plate lift cylinder to insert the lower end of the upper drive shaft 4c into the orange ball 100 and bring the upper pressure plate 4a into contact with the orange ball 100. The control circuit also controls the lift actuator 1d to bring the connecting plate 9 into contact with the connecting cap 3b. All lower transfer assemblies 3 are mounted on the same lift frame 1b, ensuring effective, synchronized connection between all lower transfer assemblies 3 and all orange-carrying columns 5, while also simplifying the structure and reducing manufacturing costs.

[0041] In the above process, the control circuit performs graphic processing on the photo. Since the brightness of the dividing line area between adjacent orange petals is significantly lower than that of the other areas, the control circuit can obtain virtual dividing lines that correspond one-to-one to the 100 dividing lines of the orange flesh ball based on the contrast of the photo.

[0042] Next, the control circuit controls the upper and lower rotating orange drive members 4b and 3a to rotate synchronously by the desired angle. During this process, the orange column 5, the orange tray 8, the orange ball 100, and the upper pressure plate 4a rotate synchronously until one of the virtual split lines coincides with the saw blade of the orange cutting assembly. The orange cutting assembly is then controlled to cause the saw blade to cut along the split line of the orange ball 100, completing one split. The above steps are repeated until the saw blade has cut along all the split lines of the orange ball 100.

[0043] Finally, the control circuit controls the pressure plate lifting cylinder to separate the upper transmission shaft 4c and the upper pressure plate 4a from the orange flesh ball 100. The control circuit also controls the lifting drive 1d to separate the connecting plate 9 and the connecting cap 3b. After the separation is completed, the control circuit controls the conveyor belt assembly 2 to operate. The conveyor belt assembly 2 continues to drive the orange column 5 and the orange flesh ball 100 to move horizontally, thereby the orange flesh ball 100 leaves the petal processing station.

[0044] Example 2: The structure and principle of this example are basically the same as those of Example 1. The basic similarities will not be described in detail, and only the differences will be described. The differences are as follows: the orange sorting machine does not include a lower orange rotating component 3, but also includes a rotation locking mechanism 6 for limiting the rotation of the orange carrying column 5 and an unlocking component 7 that can enable the rotation locking mechanism 6 to release the rotation restriction of the orange carrying column 5.

[0045] The frame 1 may not be divided into the main frame 1a and the lifting frame 1b; the orange column 5 and the supporting member 2a are rotatably connected via a second bearing 11. The second bearing 11 is not only used to improve the rotation stability of the orange column 5, but also to significantly reduce the rotational friction resistance of the orange column 5. In other words, a second bearing 11 with extremely small rotational friction resistance is preferred.

[0046] The rotation locking mechanism 6 is mounted on the carrier 2a and includes a pressure plate 6a, which is connected to the carrier 2a via a second elastic member 6b. The elastic force of the second elastic member 6b causes the pressure plate 6a to abut against the bottom surface of the orange-carrying column 5, thereby restricting the rotation of the orange-carrying column 5. This state is referred to as the locked state of the rotation locking mechanism 6. Specifically, a mounting seat 6c is fixedly connected to the carrier 2a. One end of the pressure plate 6a is pivotally connected to the mounting seat 6c via a first rotating shaft 6d. The other end of the pressure plate 6a is pivotally connected to a spring locator 6e via a second rotating shaft 6f. The spring locator 6e extends through the mounting seat 6c. A second elastic member 6b is mounted on the spring locator 6e, with one end of the second elastic member 6b abutting against the mounting seat 6c and the other end against the spring locator 6e. As a result, under the elastic force of the second elastic member 6b, the pressure plate 6a consistently tends to swing toward the bottom surface of the orange-carrying column 5.

[0047] The unlocking assembly 7 is installed on the frame 1 and is located directly below the upper turntable assembly 4. Therefore, when the supporting member 2a drives the orange-carrying column 5 to move between the unlocking assembly 7 and the upper turntable assembly 4, the unlocking assembly 7 can enable the rotation locking mechanism 6 to release the rotation restriction of the orange-carrying column 5.

[0048] The other end of the pressure plate 6a has an unlocking force-bearing portion 6a1. The unlocking assembly 7 includes an unlocking driver 7a fixed to the frame 1. The accompanying drawings show the unlocking driver 7a as a cylinder. The piston rod of the unlocking driver 7a is fixedly connected to an unlocking pusher 7b, which is positioned opposite the unlocking force-bearing portion 6a1. When the piston rod of the cylinder extends, the unlocking pusher 7b contacts the unlocking force-bearing portion 6a1 of the pressure plate 6a and pushes the pressure plate 6a to swing, thereby separating the pressure plate 6a from the bottom surface of the orange-carrying column 5. The second elastic member 6b is compressed, allowing the orange-carrying column 5 to rotate flexibly and stably. This state is referred to as the rotation locking mechanism 6 being in the unlocked state. When the piston rod of the cylinder retracts, the unlocking pusher 7b separates from the unlocking force-bearing portion 6a1 of the pressure plate 6a. Under the elastic force of the second elastic member 6b, the pressure plate 6a rests against the bottom surface of the orange-carrying column 5 again. Since the unlocking assembly 7 can be separated from the rotation locking mechanism 6, the movement of the orange-carrying column 5 and the carrier 2a is prevented from being affected.

[0049] When the upper pressure plate 4a of the upper orange rotating assembly 4 is connected to the oranges loaded on the guide section 5a and the rotation locking mechanism 6 is in the unlocked state, the control circuit controls the upper orange rotating driving member 4b of the upper orange rotating assembly 4 to rotate to the required angle. During this process, the upper pressure plate 4a, the orange flesh ball 100, the orange supporting plate 8 and the orange loading column 5 rotate synchronously; until one of the virtual splitting lines coincides with the saw blade of the orange cutting assembly.

[0050] Embodiment 3: The structure and principle of this embodiment are basically the same as those of embodiment 1. The basic similarities are not described in detail, and only the differences are described. The differences are as follows: the upper turntable assembly 4 does not have an upper turntable drive member 4b, and the upper pressure plate 4a and the upper transmission shaft 4c are rotatably connected via a third bearing; the third bearing is not only used to improve the rotation stability of the upper pressure plate 4a, but also must significantly reduce the rotational friction resistance of the upper pressure plate 4a. In other words, a third bearing with extremely small rotational friction resistance is preferred; thereby ensuring that when the control circuit controls the lower turntable drive member 3a to rotate to the required angle, the orange carrying column 5, the orange supporting plate 8, the orange meat ball 100 and the upper pressure plate 4a rotate synchronously.

[0051] Example 4: This example has essentially the same structure and principle as Example 1. The similarities are omitted here, and only the differences will be described. The differences are as follows: the frame 1 need not be divided into a main frame 1a and a lifting frame 1b; each lower turntable assembly 3 also includes a conical ring driver. Both the lower turntable driver 3a and the conical ring driver are mounted on the frame 1. The conical ring driver is connected to the conical positioning ring 3f. Obviously, the conical positioning ring 3f cannot be fixed to the frame 1. When the conical ring driver drives the conical positioning ring 3f upward, the elastic force of the first elastic member 3c3 causes the upper transmission section 3c2 to move upward until the connecting plate 9 and the connecting cap 3b are connected. As the conical ring driver drives the conical positioning ring 3f further upward, the conical positioning ring 3f separates from the conical block 3e. As the conical ring driver drives the conical positioning ring 3f downward, the connecting plate 9 and the connecting cap 3b separate, and the first elastic member 3c3 is gradually compressed.
