[0002] After the fruits are sorted, they often need to be transported and packaged. There are many ways to package fruits, such as bag packaging, box packaging and carton packaging. At present, the automatic box packaging machines for fruits on the market are often large in size and high in price. At the same price, the degree of automation is low, and the protection of the packaged fruits is not sufficient. The degree of damage to the fruits is serious, which reduces the fruit quality and economic benefits of customers.

[0003] The automatic box packaging machines seen on the market are relatively large in size and complex in structure, which provide customers with limited space for layout, restricting the effective use of customer resources. Moreover, at the same price, they have a relatively low degree of automation, which increases customers' labor costs, time costs, and usage costs. The packaging efficiency is not ideal, or the structure is not conducive to fruit protection, which damages customers' economic benefits and service experience.

[0053] The following specific embodiments illustrate the specific implementation manners of the present invention. Those skilled in the art can easily understand the advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented in other different ways, that is, without departing from the scope disclosed by the present invention, different modifications and changes can be made.

[0054] Embodiment: As Figures 1 to 19 shown, an automated gentle fruit packaging device, Figure 1 , 2 and as shown in 3, the fruit packaging device includes a support mechanism 1. The support mechanism is equipped with a horizontal bracket 2 and a horizontal driving unit 3 capable of driving the horizontal bracket to move in a horizontal plane. The horizontal bracket is equipped with a conveying bracket 4 and an up-and-down driving unit 5 capable of driving the conveying bracket to lift up and down in a vertical plane. The conveying bracket is equipped with a conveying mechanism 6 for conveying fruits and a full-box automatic induction filling device 7. Define the side where the full-box automatic induction filling device is located as the front, and the side opposite to it as the rear. The full-box automatic induction filling device is located downstream of the conveying mechanism. The full-box automatic induction filling device includes a support frame 71, and the support frame is equipped with a buffer mechanism 72 and a rotary induction discharging mechanism 73; a packing box 10 is located below the full-box automatic induction filling device;

[0055] The fruits are conveyed to the full-box automatic induction filling device through the conveying mechanism, and then fall into the packing box through the buffer mechanism and the rotary induction discharging mechanism; at the same time, the horizontal driving unit drives the horizontal bracket to move to realize the movement of the conveying mechanism and the full-box automatic induction filling device in a horizontal plane, and the up-and-down driving unit drives the conveying bracket to move to realize the lifting of the conveying mechanism and the full-box automatic induction filling device in a vertical plane. As Figure 4 shown, the support mechanism includes a bottom support frame 11 and an upper support frame 12, and the upper end of the bottom support frame is detachably connected to the lower end of the upper support frame.

[0056] The support mechanism is a height-adjustable support mechanism. The specific structure capable of realizing the height adjustment of the support mechanism is as follows: The bottom support frame 11 includes support legs 111, the support legs are provided with threads, and the upper support frame has threaded holes. The upper support frame is fixedly connected to different heights of the support legs through nuts 112 to realize the height adjustment of the support mechanism, but it is not limited to this, and other structures capable of realizing the above height-adjustable function are also acceptable.

[0057] The bottom support frame is a triangular support frame, and a reinforcing plate 113 for improving the support strength is connected between adjacent lower support legs.

[0058] In this embodiment, the support legs of the bottom support frame are welded parts of square tubes and threaded rods, and the bottom reinforcement plate is a bent sheet metal part, which has the characteristics of simple structure, high support strength and low cost, and provides support for the entire device. There are load-bearing wheels 114 at the bottom of the bottom support frame, which facilitate the overall movement of the packaging machine.

[0059] The upper support frame 12 is provided with a first photoelectric sensor mounting bracket 121 for mounting a photoelectric sensor for detecting the movement range of the detection horizontal bracket in the horizontal plane, a rotating shaft sleeve 122 for mounting the rotating shaft assembly of the horizontal bracket, and a horizontal drive unit mounting bracket 123 for mounting the horizontal drive unit.

[0060] In this embodiment, the upper support frame is mainly welded by rectangular tubes and 10-mm thick sheet metal parts, and is spray-coated as a whole after welding to improve the anti-rust and anti-corrosion capabilities, extend the service life of the structure, and at the same time play a role in decoration and beauty. The upper support frame has a simple structure, low cost and high strength. The rotating shaft sleeve is processed from high molecular polyethylene, which has high strength and high wear resistance, and can ensure small friction and stable operation during translation. The horizontal bracket can be moved left and right through the horizontal drive unit to achieve the purpose of changing boxes.

[0061] The support mechanism further includes a fruit inlet guiding buffer plate 124, and the inlet buffer guiding plate is installed on the upper support mechanism, and the height of the fruit inlet guiding buffer plate relative to the upper support frame can be adjusted. For example, it can be adjusted through oblong holes. This is prior art and will not be elaborated here.

[0062] The fruit inlet guiding buffer plate is located upstream of the conveying mechanism. The structure has the advantages of simple structure, convenient installation, high strength and low cost.

[0063] In this embodiment, the fruit inlet guiding buffer plate uses a sheet metal part as the base plate, and is covered with 6-mm thick EPE foam and 2-mm thick TPU as buffer materials. The middle of the fruit inlet guiding buffer plate is bent (such as a 150° angle), which plays a guiding role and can divide the incoming fruits into two parts, left and right, and enter the conveying mechanism. The 6-mm thick EPE foam and 2-mm thick TPU plastic skin as buffer materials can prevent fruit damage and contamination.

[0064] In this embodiment, the structure for adjusting the height between the bottom support frame and the upper support frame can adjust the height within a range of 0 - 350 mm. Between the upper support frame and the fruit inlet guiding and buffering plate, through an oblong hole, the height of the fruit inlet guiding and buffering plate can be adjusted within a small range, and the adjustable height range is between 0 - 20 mm. When the height of the fruit inlet guiding and buffering plate needs to be adjusted within a small range, the height of the inlet buffering guiding plate can be directly adjusted, thus avoiding the need to only adjust the relatively heavy horizontal support, which is convenient for adjustment, saves labor, and ensures safe operation.

[0065] The horizontal support is rotationally connected to the support mechanism. The horizontal driving unit drives the horizontal support to rotate around a certain fulcrum of the support mechanism to achieve the movement of the conveying mechanism and the full - box automatic induction filling device in the horizontal plane. One end of the horizontal driving unit is installed on the support mechanism, and the other end is installed on the horizontal support. The horizontal support rotates around the fulcrum by the telescopic movement of the horizontal driving unit.

[0066] In this embodiment, the horizontal driving unit is a linear actuator (also known as an electric cylinder), and of course, it can also be of other types, such as a cylinder, etc.

[0067] The horizontal support provides an installation bracket for the up - and - down translation driving unit. The horizontal support is mainly welded by square tubes and sheet metal parts, with low material cost, high strength, and reduced installation time.

[0068] As Figure 4 and Figure 5 shown, at the bottom of the horizontal support, there is a rotating shaft assembly 21. The rotating shaft assembly is rotationally connected to the rotating shaft sleeve 122 of the horizontal support. The rotating shaft assembly is welded by a stepped shaft with a keyway and a 10 - mm - thick sheet metal part, with high strength, ensuring the safe operation during the rotation of the translation mechanism.

[0069] As Figure 6 shown, in this embodiment, at the bottom of the horizontal support, there is also a horizontal driving unit connecting plate 22, which is welded by sheet metal parts and rectangular tubes, providing support for the horizontal driving unit.

[0070] As Figures 3 to 5 shown, at the rear end of the horizontal support, there is a conveyor belt inlet guiding plate (23). The rear end of the conveyor belt inlet guiding plate is connected to the fruit inlet guiding and buffering plate (124), and its front end is connected to the conveying mechanism. In this embodiment, the conveyor belt inlet guiding plate is composed of a 2.5 - mm - thick sheet metal part and a 2 - mm - thick TPU plastic skin, playing a role in guiding and buffering.

[0071] The horizontal bracket is rotatably connected to the rear end of the conveying bracket through a first support connecting shaft assembly 24. A tension spring assembly 20 is provided between the horizontal bracket and the conveying bracket. One end of the tension spring assembly is connected to the horizontal bracket, and the other end is connected to the conveying bracket. The conveying bracket is driven by the up-and-down driving unit to rotate with the first support connecting shaft assembly of the horizontal bracket at the rear end of the conveying bracket as the fulcrum, so as to realize the lifting of the conveying mechanism and the full-box automatic induction filling device in the vertical plane.

[0072] One end of the up-and-down driving unit is installed on the horizontal bracket, and the other end is installed on the conveying bracket. The telescopic movement of the up-and-down driving unit drives the conveying bracket to rotate with the first support connecting shaft assembly as the fulcrum.

[0073] In this embodiment, the up-and-down driving unit is a linear actuator (also known as an electric cylinder), and of course, it can also be of other types, such as a cylinder, etc.

[0074] In this embodiment, the tension spring assembly is composed of a tension spring with a wire diameter of 9 mm and an outer diameter of 55 mm and a 2-mm TPU plastic protective sleeve. The tension spring with a wire diameter of 9 mm has high strength and provides sufficient tension for the conveying mechanism to ensure safe operation.

[0075] A second support connecting shaft assembly 44 is provided at the connection between the horizontal bracket and the tension spring assembly. The conveying mechanism is installed on the second support connecting shaft assembly.

[0076] In this embodiment, the second support connecting shaft assembly is welded by a sheet metal part with a thickness of 10 mm and a bushing with an outer diameter of 30 mm, which is used to connect the conveying mechanism and enable the conveying mechanism to move in the vertical plane.

[0077] As Figure 7 and Figure 8 shown, a photoelectric sensor 30 for detecting the moving amplitude of the full-box automatic induction filling device in the vertical plane is provided at the rear end of the conveying bracket.

[0078] In this implementation, the horizontal driving unit provides left and right translation in the horizontal plane for the packaging equipment, the up-and-down driving unit provides movement in the vertical plane for the packaging equipment, and the tension spring assemblies on both sides connect the horizontal brackets of the conveying mechanism, enabling the conveying mechanism and the front-end full-box automatic induction filling device to achieve stable horizontal movement and up-and-down movement.

[0079] As Figure 7 and Figure 8As shown, the conveying mechanism 6 includes a conveyor belt 61, a driving roller assembly 62, and a driven roller assembly 63. The driving roller assembly and the driven roller assembly are installed on the conveying support. The conveyor belt is sleeved on the driving roller assembly and the driven roller assembly, and the conveyor belt is driven to reciprocate by the driving roller assembly and the driven roller assembly.

[0080] As Figure 7 and Figure 8 shown, the conveying support 4 includes a rear section support 41 and a front section support 42. The rear end support is inclined obliquely upward from back to front, and the front section support is inclined obliquely downward from back to front. The conveying mechanism further includes a guide wheel assembly 64 for guiding the conveyor belt. The guide wheel assembly is installed at the connection of the rear section support and the front section support.

[0081] The conveyor belt is a split belt, which means a belt provided with a plurality of spaced-apart partition strips 611 along the conveying direction of the conveyor belt. Fruits are located in the spaces formed by adjacent partition strips.

[0082] The conveying mechanism 6 further includes a guide curtain assembly 65 installed on the conveying support. The guide curtain assembly is located above the conveyor belt corresponding to the front section support. Fruits pass between the conveyor belt and the guide curtain assembly. The conveying support uses a sheet metal part as the support framework, with low cost.

[0083] In this embodiment, the included angle between the front section support and the rear section support is 113°. Of course, it can also be other angles and can be designed according to actual requirements.

[0084] The conveyor belt adopts a split belt, which can better prevent the mutual collision of easily damaged items such as fruits.

[0085] The guide wheel assembly installed at the connection of the rear section support and the front section support plays a guiding role, guiding the conveyor belt to run more smoothly.

[0086] As Figure 7 and Figure 8 shown, the conveying mechanism further includes a support wheel assembly 66 for improving the conveying stability of the conveyor belt. In this embodiment, the support wheel assembly is installed on the rear end support. Since the length of the rear section support is relatively long, using the support wheel assembly can improve the conveying stability of the conveyor belt.

[0087] As Figure 7 and Figure 8As shown in the figure, a separator strip 43 for preventing the conveyor belt from deviating is provided in the middle of the upper surface of the conveyor belt. The separator strip can be fixed to the conveying bracket or fixed to the conveyor belt and conveyed with it. In this embodiment, it is the former, and the separator strip is a high molecular polyethylene separator strip, but it is not limited thereto.

[0088] In this embodiment, the connection between the conveying bracket and the horizontal bracket adopts a shaft connection to achieve translation and elevation, with low design and production costs and convenient maintenance.

[0089] As Figures 9 to 11 shown in the figure, the buffer mechanism includes a buffer brush 721 and a rotary drive mechanism, and the buffer brush is driven to rotate by the rotary drive mechanism.

[0090] In this embodiment, the buffer brush is made of food-grade nylon filaments with an outer diameter of 0.76 mm, which are adhesively bonded at the ends to form a nylon cluster with a diameter of 25 mm. The nylon cluster is split at about 25 mm in length at the end. After splitting, it is softer and will not damage the fruit cup, increasing friction, preventing the accumulation of fruits on the guiding and peeling surface of the rotary discharging structure, and guiding the fruits to enter the packing box from the discharging port.

[0091] As Figures 13 to 15 shown in the figure, the rotary drive mechanism includes a speed reducer assembly 722 and a chain drive assembly 723. The chain drive assembly includes a tensioning wheel 7231, a chain 7232, and a plurality of sprockets. The chain is wound around the tensioning wheel and the sprockets. The sprockets include a first sprocket 7233 connected to the output end of the speed reducer assembly and a second sprocket 7234 connected to the buffer brush.

[0092] In this embodiment, the sprocket further includes a third sprocket 7235 connected to the conveying mechanism. The third sprocket is connected to the driving roller assembly of the conveying mechanism to provide power for the conveying mechanism.

[0093] The chain drive assembly can provide rotational power for the buffer brush structure. The tensioning wheel can ensure that the chain will not fall off during operation and can improve the transmission efficiency. At the same time, the chain drive assembly in this example also drives the driving roller assembly of the conveyor belt to provide power for the conveying mechanism, improving the utilization rate of electric energy and reducing costs. Of course, the conveying mechanism can also adopt a separate power drive unit.

[0094] The speed reducer assembly provides the original power for the operation of the buffer brush and the conveying mechanism.

[0095] As Figures 9 to 11As shown in the figure, the rotary induction discharging mechanism includes a rotary discharging assembly 731, a full-box automatic inductor 732, a lifting assembly 733, and a rotary driving unit 734 capable of driving the rotary discharging assembly and the lifting assembly to rotate. The lifting assembly is installed on the rotary discharging assembly. The rotary discharging assembly is driven by the rotary driving unit to discharge materials, and the filling degree of fruits in the packing box is sensed through the cooperation of the lifting assembly and the full-box automatic inductor. The full-box automatic induction filling device has the advantages of simple structure, convenient installation, high strength, and low cost, and has a good protective effect on fruits during the packing process.

[0096] As Figures 9 to 11 shown in the figure, the support frame is provided with a longitudinally extending partition plate 711. The support frame is divided into left and right parts by the partition plate, so that the fruits can come out separately in the left and right parts. The advantage of this design is that it can prevent the collision between fruits. In this embodiment, a suspended partition plate is adopted, which can provide a transmission space for the rotary discharging structure at the lower end, improve the space utilization rate, and reduce the structural cost.

[0097] As Figures 13 to 15 shown in the figure, the support frame is provided with a first buffer guiding curtain 712, a second buffer guiding curtain 713, and a third buffer guiding curtain 714 at the moving track of the fruits. The first buffer guiding curtain, the second buffer guiding curtain, and the third buffer guiding curtain are all made of food-grade 3mm thick PU leather, which has high tensile and tear resistance strength, improves the service life, avoids fruit damage, and does not pollute the fruits. And they are connected to the support frame by sheet metal pressing strips and bolts, which is convenient for installation and maintenance.

[0098] A buffer guiding plate 715 is provided below the first buffer guiding curtain.

[0099] The part of the support frame in contact with the fruits is provided with side anti-collision buffer EPE foam. The side anti-collision buffer EPE foam is composed of 10mm EPE foam covered with 0.3mm TPU pasted on the sheet metal part. The EPE foam has good buffering effect, which can prevent the fruits from directly hitting the sheet metal part and being bruised when entering from the entrance. 0.3mm TPU is a food-grade raw material, which does not pollute the fruits and is convenient for cleaning.

[0100] As Figures 16 to 18 shown in the figure, the rotary discharging assembly 731 includes a hollow rotary shaft 7311, a core rod 7312, an elastic resetting member 7313, and a discharging frame 7314. The discharging frame is arranged on the rotary shaft, and the discharging frame is provided with a rotary discharging structure;

[0101] The lifting component is installed on the discharge rack, and the end close to the core rod is located directly below the core rod. The core rod is located inside the rotating shaft. The elastic resetting member is installed at the lower end of the core rod. When the fruits in the packing box push the lifting component to jack up the core rod, and under the action of the elastic resetting member, the core rod returns to its original position.

[0102] In this embodiment, the rotation driving unit is a reduction motor. In this embodiment, the full-box automatic sensor is a photoelectric sensor. The full-box automatic sensor is installed on the outer shell of the reduction motor. By detecting the upper end of the core rod with the full-box automatic sensor, the filling degree of the fruits can be judged. In this embodiment, the elastic resetting member includes a reset spring and a stop head. The reset spring is sleeved on the core rod, and one end of it abuts against the stop head while the other end abuts against the rotating shaft.

[0103] As Figure 12 and 17 shown, the lifting component 733 includes a baffle curtain 7331, a baffle rod 7332 and a baffle plate 7333. The upper end of the baffle curtain is installed on the baffle rod. The baffle plate is installed on the side of the baffle rod close to the core shaft and is located directly below the core shaft.

[0104] In this embodiment, the baffle curtain is cut and sewn from food-grade 3mm thick PU, and the baffle plate is a welding plate welded to the baffle rod.

[0105] In this embodiment, as Figure 10 、 16 and shown in 18, a plug 73121 is installed at the upper end of the core rod. By detecting the upper end of the core rod with the full-box automatic sensor, the filling degree of the fruits can be judged. The function of the rotating discharge assembly is to transmit rotational power to the rotating outlet, and the function of the core rod is to provide a limiting function for the full-box automatic induction filling device.

[0106] As Figure 16 and Figure 17 shown, the discharge rack includes a plurality of hanging rods 73141 arranged at intervals in the circumferential direction. Each hanging rod extends radially. The rotating discharge structure includes a guiding hanging skin 73151 and a hanging skin through rod 73152. The hanging skin through rod is arc-shaped. One side of the guiding hanging skin passes through the hanging rod, and the other side passes through the hanging skin through rod. Each guiding hanging skin is in an arc shape and tapers from top to bottom and forms a discharge port at its end. In this embodiment, the guiding hanging skin is also provided with a buffer protrusion 73153, and the buffer protrusion is directly sewn on the guiding hanging skin.

[0107] The guiding hanging skin is cut and sewn from food-grade 3mm thick PU, and the buffer protrusion is directly sewn on the buffer guiding hanging skin.

[0108] This kind of rotary discharging structure can greatly reduce the impact during fruit discharging, avoid fruit damage to the greatest extent. At the same time, the rotary discharging port is conducive to improving the efficiency of automatic discharging, reducing mutual bruising between fruits, and can also play a certain role in preventing fruit accumulation at the outlet.

[0109] As Figure 19 shown, the filling device further includes a control box 8. The control box is provided with a control system. The control box includes a control box housing 81, an emergency stop switch 82, a power isolation protection switch 83, a control panel 84, and a warning buzzer 85 provided on the control box housing. The emergency stop switch 82, the power isolation protection switch 83, the control panel 84, and the warning buzzer 85 are respectively connected to the controller of the control system. The warning buzzer can well reflect the working state of the packaging equipment. The power isolation protection switch can effectively turn on and off the power supply and protect the device. The emergency stop switch can reflect the working state and alarm to ensure the safety of personnel and the equipment.

[0110] As Figure 1 shown, the packaging equipment further includes a packing box induction and separation mechanism 9. The packing box induction and separation mechanism includes a photoelectric sensor 30 for sensing the presence or absence of a packing box and a separation pipe 91 for separating the packing box left and right. The photoelectric sensor is installed on the support mechanism.

[0111] The separation pipe provides a separation pipe for the left and right packing boxes, and at the same time provides ground support for the packaging equipment to enhance the overall stability of the structure.

[0112] The working principle and process of the present invention are as follows:

[0113] Install the device on the fruit sorting machine equipment and power on the device. At this time, the full-box automatic induction filling device is at a high position in the working position, as Figure 2As shown in the figure, at this time, the buffer brush of the buffer mechanism of the conveying mechanism and the full-box automatic induction filling device does not work. Place the packaging box at the packaging box induction and separation mechanism. The packaging box blocks the light source of the photoelectric sensor of this mechanism, and the photoelectric sensor transmits the recognition signal to the control system in the control box. The control element recognizes through the system that there is a packaging box in the packaging position, and transmits the control signal to the horizontal drive unit. The brake rod of the horizontal drive unit extends or contracts (whether it extends or contracts is determined according to the actual control software setting program). Under the action of the horizontal drive unit, the conveying mechanism and the full-box automatic induction filling device start to move left or right around the rotating shaft assembly. After the signal of the photoelectric sensor used to detect the translation amplitude is blocked when moving, the signal is transmitted to the control system, and the control system sends the signal to stop working to the horizontal drive unit, and the horizontal drive unit stops working; at the same time, the entire upper mechanism (referring to the mechanisms installed on the horizontal bracket) stops moving left and right. At the same time, after the control software receives the signal, it transmits the control signal to the up and down drive unit. The brake rod of the up and down drive unit starts to extend, and the conveying mechanism and the full-box automatic induction filling device start to lower the height until the appropriate set height in the packaging box is reached. At this time, the photoelectric signal of the photoelectric sensor installed on the conveying bracket for detecting the movement amplitude of the full-box automatic induction filling device in the vertical plane will be blocked, so that the signal is transmitted to the control box, and the control box sends the feedback signal to the up and down drive unit, and the brake rod of the up and down drive unit stops moving;

[0114] At the same time, the working signal is transmitted to the speed reducer assembly of the full-box automatic induction filling device. The speed reducer assembly is powered on and runs. It starts to rotate through the speed reducer assembly, and drives the buffer brush to start rotating through the chain drive assembly. The isolation strips on the conveyor belt can separate the fruits brought in by the conveyor belt and enter the conveyor belt from both sides respectively. When the fruits reach the full-box automatic induction filling device through the conveyor belt, the fruits are divided into left and right parts by the partition plate provided on the support frame. The fruits first pass through the guiding buffer of the first buffer guiding curtain and the first buffer deceleration of the buffer brush, and then pass through the second buffer guiding of the buffer guiding plate. At this time, the fruits enter the guiding hanging skin for the third buffer. After the fourth buffer of the buffer protrusion, they safely fall into the packaging box; the discharge port of the guiding hanging skin not only serves as a buffer guiding outlet, but also can push the fruits piled up at the outlet flat during its continuous rotating operation of packing, so as to prevent the fruits from piling up; and the third buffer guiding curtain and the buffer brush play a role of guiding buffer for the fruits, and can also be used as a baffle to prevent the fruits from falling and being damaged;

[0115] When the fruits in the packing box reach a certain height, the fruits will lift the lifting plate assembly, jack up the core rod, and the lifting height of the core rod is limited between 5-10 mm. When the core rod rises to a certain height, the plug at the top will block the light source signal of the photoelectric sensor at the speed reduction motor. The photoelectric sensor transmits the signal to the control system through the signal line. The control system generates an output signal to the upper and lower driving units according to the set system software. The brake rod of the upper and lower driving units slowly contracts, and the conveying mechanism and the full-box automatic induction filling device are lifted to the system-set height (generally, the lifting amplitude is about 20 cm). At the same time, the core rod descends, and the photoelectric signal of the photoelectric signal sensor returns. This process repeats until the fruits in the packing box are filled to the set weight. The full-box signal is transmitted to the control system, and the control system outputs a signal to the full-box automatic induction filling device, and the conveying mechanism, the buffer mechanism, and the rotary discharging assembly stop working. At the same time, the brake rod of the upper and lower driving units contracts, and the conveying mechanism and the full-box automatic induction device are lifted to the box-changing height. The photoelectric signal of the photoelectric sensor used to detect the moving amplitude of the full-box automatic induction filling device in the vertical plane will be blocked, and the feedback signal is sent to the control system. The control system issues a command signal, and the brake rod of the upper and lower driving units stops contracting. The brake rod of the horizontal driving unit begins to contract. The conveying mechanism and the full-box automatic induction filling device are driven by the brake rod of the horizontal driving unit and start to move right (or left) horizontally, repeating the actions of the initial conveying mechanism and the full-box automatic induction filling device to achieve automatic box-changing. After the box-changing is completed, the packing work starts again. At the same time, the packed packing box can be transferred, and a new empty packing box can be placed at the same time.

[0116] Of course, the lifting, translation, and induction packing processes can also be manually controlled according to the control panel on the control box. The control box 8 mainly installs control components and wiring, and there will be corresponding control components or circuit boards inside. The control box is equipped with a control system. The control box is equipped with a control system, and the control box includes a control box housing 81, an emergency stop switch 82, a power isolation protection switch 83, a control panel 84, and a warning buzzer 85 provided on the control box housing. The emergency stop switch 82, the power isolation protection switch 83, the control panel 84, and the warning buzzer 85 are respectively connected to the controller of the control system.. The warning buzzer can well reflect the working state of the packaging equipment. The power isolation protection switch can effectively switch on and off the power supply and protect the device. The emergency stop switch can reflect the working state and give an alarm to ensure the safety of personnel and equipment. The control panel can manually select the working mode, the automatic mode and the manual mode.

[0117] The present invention is mainly used for a fruit packaging device for boxed packaging of fruit sorting equipment, realizing the functions of packing and box-changing, but does not exclude the application of an automatic induction structure on other similar equipment.

[0118] The above are only embodiments of the present invention, and do not thereby limit the patent scope of the present invention. Any equivalent structures made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are similarly included within the patent protection scope of the present invention.
