Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable sorting technology, and in particular to a packing device and a fruit and vegetable sorting machine. Background Technology

[0002] As people pursue a higher quality of life, more and more people are demanding higher quality fruits, making fruit sorting an important technology. Fruit sorting involves packing fruits and vegetables into boxes. Currently, the fruits and vegetables are typically transported to receiving trays, and then manually poured into the boxes. This method of packing is inefficient. Utility Model Content

[0003] The present invention aims to provide a packing device and a fruit and vegetable sorting machine to solve the technical problem of low efficiency in the existing fruit and vegetable packing methods.

[0004] The technical problem solved by this utility model embodiment is addressed by the following technical solution:

[0005] A boxing device is provided, including a fruit receiving tray, a drive assembly, and a support frame;

[0006] The fruit receiving tray is hinged to the support frame. The fruit receiving tray includes a first fruit inlet and a second fruit inlet. The first fruit inlet and the second fruit inlet are located at opposite ends of the fruit receiving tray. A first working position is provided below the first fruit inlet, and a second working position is provided below the second fruit inlet. The first working position and the second working position are respectively used to hold fruit boxes.

[0007] The drive assembly is connected to the fruit receiving tray to drive the first fruit inlet of the fruit receiving tray to tilt toward the first working position or drive the second fruit inlet of the fruit receiving tray to tilt toward the second working position.

[0008] In this embodiment, a drive component tilts the first inlet of the fruit receiving tray toward the first workstation, allowing the fruits and vegetables in the tray to be poured into the loading box at the first workstation. Once the loading box at the first workstation is full or reaches a preset weight, the drive component then tilts the second inlet of the fruit receiving tray toward the second workstation, allowing the fruits and vegetables in the tray to be poured into the loading box at the second workstation. Simultaneously, the user can remove the loading box already filled at the first workstation and place an empty loading box there. When the loading box at the second workstation is full or reaches a preset weight, the above steps are repeated until the loading operation is complete.

[0009] In this embodiment, the first and second fruit-pouring ports of the fruit receiving tray are switched between the first and second workstations by the drive component, thereby enabling switching between the first and second workstations for fruit loading, resulting in high fruit loading efficiency.

[0010] In one embodiment, the packing device further includes a control unit, which is communicatively connected to the drive assembly.

[0011] In this embodiment, by setting up a control unit, the drive components can be easily controlled.

[0012] In one embodiment, the packing device further includes a first weighing sensor and a second weighing sensor. The first weighing sensor is located at the first work station and below the first fruit inlet, and the second weighing sensor is located at the second work station and below the second fruit inlet.

[0013] The control unit is also communicatively connected to the first weighing sensor and the second weighing sensor, respectively.

[0014] In this embodiment, when the fruit receiving tray pours fruit into the fruit box at the first workstation through the first pouring port, and when the fruit box reaches a preset weight, the control unit can control the drive assembly to tilt the first pouring port of the receiving tray away from the first workstation. Simultaneously, the drive assembly drives the second pouring port of the receiving tray to tilt towards the second workstation. At this time, the receiving tray pours fruit into the fruit box at the second workstation through the second pouring port. Therefore, in this embodiment, the switching between the first and second pouring ports can be controlled by the control unit, and can also be controlled according to the preset weight set by the user in the control unit, thus meeting various user needs.

[0015] In one embodiment, the packing device further includes a first sensing component and a second sensing component. The first sensing component is disposed at the first work station to sense whether the fruit box is placed at the first work station, and the second sensing component is disposed at the second work station to sense whether the fruit box is placed at the second work station.

[0016] The control unit is also communicatively connected to the first sensing component and the second sensing component, respectively.

[0017] In this embodiment, by setting a first sensing component, it is possible to sense whether the fruit box at the first workstation is placed in the correct position, thus ensuring that the fruits and vegetables on the receiving tray fall accurately into the fruit box at the first workstation through the first fruit pouring spout. Similarly, by setting a second sensing component, it is possible to sense whether the fruit box at the second workstation is placed in the correct position, thus ensuring that the fruits and vegetables on the receiving tray fall accurately into the fruit box at the second workstation through the second fruit pouring spout. By setting a control unit, unified and coordinated control can be achieved.

[0018] In one embodiment, the first sensing component includes a first photoelectric switch and a first arc-shaped contact piece. The first arc-shaped contact piece and the first photoelectric switch are disposed at the first work station. After the fruit box is placed at the first work station, the first arc-shaped contact piece can trigger the first photoelectric switch.

[0019] The second sensing component includes a second photoelectric switch and a second arc-shaped contact piece. The second arc-shaped contact piece and the second photoelectric switch are located at the second work station. After the fruit box is placed at the second work station, the first arc-shaped contact piece can trigger the second photoelectric switch.

[0020] The control unit is communicatively connected to the first photoelectric switch and the second photoelectric switch, respectively.

[0021] In this embodiment, when the fruit box is placed at the first workstation, it pushes the first arc-shaped contact piece, triggering the first photoelectric switch. Upon triggering, the first photoelectric switch sends a first signal to the control unit, indicating that the fruit box at the first workstation is in place. The control unit can then control the drive assembly to tilt the first fruit-pouring opening of the fruit-receiving tray towards the first workstation. When the fruit box is placed at the second workstation, it pushes the second arc-shaped contact piece, triggering the second photoelectric switch. Upon triggering, the second photoelectric switch sends a second signal to the control unit, indicating that the fruit box at the second workstation is in place. The control unit can then control the drive assembly to tilt the second fruit-pouring opening of the fruit-receiving tray towards the second workstation. By setting up the control unit, unified and coordinated control can be achieved. The first and second arc-shaped contact pieces are both arc-shaped. This design ensures elastic contact between the fruit box and the first arc-shaped contact piece, and between the fruit box and the second arc-shaped contact piece. This avoids damage to the fruit box, the first arc-shaped contact piece, and the second arc-shaped contact piece, and also ensures timely triggering of the first and second photoelectric switches.

[0022] In one embodiment, the first sensing component further includes a first mounting frame, a first hinge shaft, and a first limiting shaft. The first mounting frame is provided with a first mounting groove, and the two opposite side walls of the first mounting groove are respectively provided with a first hinge hole and a first arc-shaped hole.

[0023] The first arc-shaped contact piece is provided with the first hinge shaft at both ends. Each first hinge shaft is engaged with a corresponding first hinge hole so that the first arc-shaped contact piece is hingedly installed in the first mounting groove. The first arc-shaped contact piece can tilt towards the first weighing sensor under its own weight. The first arc-shaped contact piece is provided with the first limiting shaft at both ends. The two first limiting shafts are engaged with the corresponding first arc-shaped holes to limit the rotation of the first arc-shaped contact piece.

[0024] The second sensing component also includes a second mounting frame, a second hinge shaft, and a second limiting shaft. The second mounting frame is provided with a second mounting groove, and the two opposite side walls of the second mounting groove are respectively provided with a second hinge hole and a second arc-shaped hole.

[0025] The second arc-shaped contact piece is provided with a second hinge shaft at both ends. Each second hinge shaft is engaged with a corresponding second hinge hole so that the second arc-shaped contact piece is hingedly installed in the second mounting groove. The second arc-shaped contact piece can tilt towards the second sensor under its own weight. The second arc-shaped contact piece is provided with a second limiting shaft at both ends. The two second limiting shafts are engaged with the corresponding second arc-shaped holes to limit the rotation of the second arc-shaped contact piece.

[0026] In this embodiment, the two first hinge shafts are coaxially arranged, and each first hinge shaft passes through a corresponding first hinge hole. This arrangement allows the first arc-shaped contact piece to rotate hingedly relative to the first mounting frame. Furthermore, since the two first limiting shafts pass through corresponding first arc-shaped holes, the cooperation between the first limiting shafts and the first arc-shaped holes can limit the movement of the first arc-shaped contact piece, preventing it from getting too close to the first workstation or the first photoelectric switch. Moreover, the first arc-shaped contact piece can tilt towards the first workstation under its own weight. This arrangement allows the first arc-shaped contact piece to rotate towards the first photoelectric switch when a fruit box is placed at the first workstation, triggering the first photoelectric switch. When the fruit box is removed from the first workstation, the first arc-shaped contact piece can tilt towards the first workstation under its own weight, returning it to its initial position, thus serving a resetting function. Similarly, the two second hinge shafts are coaxially arranged, each passing through a corresponding second hinge hole. This arrangement allows the second arc-shaped contact piece to rotate hingedly relative to the second mounting frame. Furthermore, since the two second limiting shafts pass through corresponding second arc-shaped holes, the cooperation between the second limiting shafts and the second arc-shaped holes limits the movement of the second arc-shaped contact piece, preventing it from getting too close to the second workstation or the second photoelectric switch. Moreover, the second arc-shaped contact piece can tilt towards the second workstation under its own weight. This arrangement allows it to rotate towards the second photoelectric switch when a fruit box is placed at the second workstation, triggering the switch. When the fruit box is removed from the second workstation, the second arc-shaped contact piece tilts back towards the second workstation under its own weight, returning to its initial position and thus serving a reset function.

[0027] In one embodiment, the packing device further includes an alarm component, and the control unit is also communicatively connected to the alarm component.

[0028] In this embodiment, the alarm component can emit an alarm sound or activate an alarm via light. Unified and coordinated control can be achieved by setting up a control unit.

[0029] In one embodiment, the driving assembly includes a driving element, one end of which is hinged to the support frame and the other end of which is hinged to the bottom of the fruit receiving tray, so as to drive the first fruit inlet of the fruit receiving tray to tilt toward the first working position or drive the second fruit inlet of the fruit receiving tray to tilt toward the second working position.

[0030] In this embodiment, when the telescopic end of the drive element pushes the first fruit-discharging opening downwards, the first fruit-discharging opening tilts towards the first working position, and the second fruit-discharging opening tilts away from the second working position. By setting the drive element, the rotation control of the fruit tray is facilitated. The drive element and the control unit are communicatively connected, and unified control is achieved through the control unit.

[0031] In one embodiment, the drive assembly further includes a fixed housing, which includes a mounting plate and two side plates. The mounting plate is disposed on the support frame, and the two side plates are connected to opposite sides of the mounting plate. A receiving channel is formed between the two side plates and the mounting plate. One end of the drive element is hinged to the mounting plate and located within the receiving channel.

[0032] In this embodiment, the mounting plate is used to mount the driving element, and the receiving channel formed by the two side plates and the mounting plate is used to accommodate the driving element. The receiving channel protects the driving element and also limits its movement. When the telescopic end of the driving element extends or retracts, and both ends of the driving element are hinged and rotated, the driving element remains within the receiving channel and will not deviate excessively.

[0033] On the other hand, this utility model also provides a fruit and vegetable sorting machine, including the aforementioned packing device.

[0034] Compared with existing technologies, in this invention's packing device, users can transport fruits and vegetables to the receiving tray via a belt conveyor or manually. Before packing, the packing boxes are pre-placed at the first and second workstations. A drive assembly tilts the first inlet of the receiving tray towards the first workstation, allowing the fruits and vegetables in the tray to flow into the packing box at the first workstation. Once the packing box at the first workstation is full or reaches a preset weight, the drive assembly then tilts the second inlet of the receiving tray towards the second workstation, allowing the fruits and vegetables to flow into the packing box at the second workstation. Simultaneously, the user can remove the packing box already filled at the first workstation and place an empty packing box there. Once the packing box at the second workstation is full or reaches a preset weight, the above steps are repeated until the packing operation is complete.

[0035] In this invention, the first and second fruit-discharging ports of the fruit receiving tray are switched between the first and second working positions by the drive component, thereby enabling switching between the first and second working positions for fruit loading. Therefore, the fruit and vegetable loading device of this invention has high efficiency. Attached Figure Description

[0045] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0046] The following detailed description, in conjunction with all the accompanying drawings, describes a packing device 100 and a fruit and vegetable sorting machine provided in this application through specific embodiments.

[0047] Please refer to Figure 1 and Figure 2One embodiment of this utility model discloses a boxing device 100, including a fruit receiving tray 10, a driving assembly 20, and a support frame 30. The fruit receiving tray 10 is hinged to the support frame 30. The fruit receiving tray 10 includes a first fruit inlet 12 and a second fruit inlet 14, which are located at opposite ends of the fruit receiving tray 10. A first working position 101 is provided below the first fruit inlet 12, and a second working position 102 is provided below the second fruit inlet 14. The first working position 101 and the second working position 102 are respectively used to hold fruit boxes. The driving assembly 20 is connected to the fruit receiving tray 10 to drive the first fruit inlet 12 of the fruit receiving tray 10 to tilt toward the first working position 101 or drive the second fruit inlet 14 of the fruit receiving tray 10 to tilt toward the second working position 102.

[0048] In this embodiment, the user can transport fruits and vegetables to the receiving tray 10 via a belt conveyor or manually. Before loading, the fruit boxes are pre-placed at the first station 101 and the second station 102. The first inlet 12 of the receiving tray 10 is tilted towards the first station 101 by the drive assembly 20, so that the fruits and vegetables in the receiving tray 10 are poured into the fruit box at the first station 101 through the first inlet 12. When the fruit box at the first station 101 is full or reaches a preset weight, the second inlet 14 of the receiving tray 10 is tilted towards the second station 102 by the drive assembly 20, so that the fruits and vegetables in the receiving tray 10 are poured into the fruit box at the second station 102 through the second inlet 14. At the same time, the user can move the fruit box with fruits and vegetables loaded at the first station 101 away and place an empty fruit box at the first station 101. Once the fruit box at the second workstation 102 is full or reaches the preset weight, repeat the above steps until the fruit loading operation is completed.

[0049] The above is just an example of fruit loading operations; it can be understood that loading can also begin from the second station 102. The user can control the drive assembly 20 via a built-in switch or an external control unit. The middle part of the fruit receiving tray 10 is hinged to the top of the support frame 30 via a pivot or similar means. The first station 101 and the second station 102 refer to the areas used for placing fruit boxes.

[0050] In this embodiment, the first fruit-pouring port 12 and the second fruit-pouring port 14 of the fruit receiving tray 10 are controlled by the drive component 20 to switch between the first work station 101 and the second work station 102, thereby enabling switching between the first work station 101 and the second work station 102 for fruit loading. Therefore, the fruit and vegetable loading efficiency of the packing device 100 in this embodiment is high.

[0051] To facilitate control of the drive component 20, in one embodiment, the packing device 100 further includes a control unit, which is communicatively connected to the drive component 20.

[0052] In this embodiment, the control unit can be a control module in the sorting system; specifically, the control unit can be a PLC controller. The control unit and the drive component 20 can be electrically connected or connected via signals. By setting up the control unit, the drive component 20 can be easily controlled.

[0053] In one embodiment, the packing device 100 further includes a first weighing sensor 40 and a second weighing sensor 50. The first weighing sensor 40 is located at the first station 101 and below the first fruit inlet 12. The second weighing sensor 50 is located at the second station 102 and below the second fruit inlet 14. The control unit is also communicatively connected to the first weighing sensor 40 and the second weighing sensor 50 respectively.

[0054] When the receiving tray 10 pours fruit into the fruit box at the first workstation 101 through the first pouring port 12, and when the fruit box reaches the preset weight, the control unit can control the drive assembly 20 to tilt the first pouring port 12 of the receiving tray 10 away from the first workstation 101. Simultaneously, the drive assembly 20 drives the second pouring port 14 of the receiving tray 10 to tilt towards the second workstation 102. At this time, the receiving tray 10 pours fruit into the fruit box at the second workstation 102 through the second pouring port 14. Therefore, in this embodiment, the switching between the first pouring port 12 and the second pouring port 14 can be controlled by the control unit, and can also be controlled according to the preset weight set by the user in the control unit, thus meeting various user needs. The control unit and the first weighing sensor 40 and the second weighing sensor 50 can be electrically connected or connected via signal. By setting the control unit, unified and coordinated control can be achieved.

[0055] The preset weight can be customized according to user needs. For example, the preset weight can be 10kg. When the receiving tray 10 pours fruit into the fruit box at the first workstation 101 through the first pouring port 12, and when the first weighing sensor 40 detects that the weight of the fruit box has reached 10kg, the control unit controls the drive assembly 20 to switch the receiving tray 10 from the first pouring port 12 to the second pouring port 14. The first workstation 101 refers to the area where the first weighing sensor 40 is placed, and the second workstation 102 refers to the area where the second weighing sensor 50 is placed.

[0056] In one embodiment, the packing device 100 further includes a first sensing component 60 and a second sensing component 70. The first sensing component 60 is located at a first station 101 to sense whether a fruit box is placed at the first station 101. The second sensing component 70 is located at a second station 102 to sense whether a fruit box is placed at the second station 102. The control unit is also communicatively connected to the first sensing component 60 and the second sensing component 70 respectively.

[0057] By setting the first sensing component 60, it can sense whether the fruit box at the first workstation 101 is placed in the correct position, thus ensuring that the fruits and vegetables from the receiving tray 10 fall accurately into the fruit box at the first workstation 101 through the first fruit pouring opening 12. Similarly, by setting the second sensing component 70, it can sense whether the fruit box at the second workstation 102 is placed in the correct position, thus ensuring that the fruits and vegetables from the receiving tray 10 fall accurately into the fruit box at the second workstation 102 through the first fruit pouring opening 12. The control unit can be electrically connected to the first sensing component 60 and the second sensing component 70, or connected via a signal. By setting the control unit, unified and coordinated control can be achieved.

[0058] Please refer to the above as well. Figures 3 to 5 In one embodiment, the first sensing component 60 and the second sensing component 70 have the same or similar structures. The first sensing component 60 includes a first photoelectric switch 62 and a first arc-shaped contact 64. The first arc-shaped contact 64 and the first photoelectric switch 62 are located at the first workstation 101, with the first photoelectric switch 62 positioned on the side of the first arc-shaped contact 64 furthest from the first weighing sensor 40. That is, the first photoelectric switch 62 and the first weighing sensor 40 are located on opposite sides of the first arc-shaped contact 64. When a fruit box is placed at the first workstation 101, the first arc-shaped contact 64 can trigger the first photoelectric switch 62. The second sensing component 70 includes a second photoelectric switch 72 and a second arc-shaped contact 74. The second arc-shaped contact 74 and the second photoelectric switch 72 are located at the second workstation 102, with the second photoelectric switch 72 positioned on the side of the second arc-shaped contact 74 furthest from the second weighing sensor 50. That is, the second photoelectric switch 72 and the second weighing sensor 50 are located on opposite sides of the second arc-shaped contact 74. After a fruit box is placed at the second workstation 102, the first arc-shaped contact 64 can trigger the second photoelectric switch 72; the control unit is communicatively connected to the first photoelectric switch 62 and the second photoelectric switch 72 respectively.

[0059] In this embodiment, when the fruit box is placed at the first station 101, the fruit box pushes the first arc-shaped contact piece 64, which triggers the first photoelectric switch 62. After being triggered, the first photoelectric switch 62 sends a first signal to the control unit, indicating that the fruit box at the first station 101 has been installed in place. The control unit can then control the drive assembly 20 to tilt the first fruit-pouring opening 12 of the fruit receiving tray 10 towards the first station 101. When the fruit box is placed at the second station 102, the fruit box pushes the second arc-shaped contact piece 74, which triggers the second photoelectric switch 72. After being triggered, the second photoelectric switch 72 sends a second signal to the control unit, indicating that the fruit box at the second station 102 has been installed in place. The control unit can then control the drive assembly 20 to tilt the second fruit-pouring opening 14 of the fruit receiving tray 10 towards the second station 102. The control unit, the first photoelectric switch 62, and the second photoelectric switch 72 can be electrically connected or connected via signals. By setting up the control unit, unified and coordinated control can be achieved. The first arc-shaped contact piece 64 and the second arc-shaped contact piece 74 are arc-shaped. This design allows for elastic contact between the fruit box and the first arc-shaped contact piece 64, and between the fruit box and the second arc-shaped contact piece 74. This avoids damage to the fruit box, the first arc-shaped contact piece 64 and the second arc-shaped contact piece 74, and also ensures that the first photoelectric switch 62 and the second photoelectric switch 72 can be triggered in a timely manner.

[0060] In one embodiment, the first sensing component 60 further includes a first mounting frame 66, a first hinge shaft, and a first limiting shaft. The first mounting frame 66 is provided with a first mounting groove 662, and the opposite side walls of the first mounting groove 662 are respectively provided with a first hinge hole 664 and a first arc-shaped hole 666. The two ends of the first arc-shaped contact piece 64 are respectively provided with a first hinge shaft, and the two first hinge shafts respectively cooperate with the corresponding first hinge hole 664 so that the first arc-shaped contact piece 64 is hingedly installed in the first mounting groove 662. The first arc-shaped contact piece 64 can tilt towards the first station 101 under its own weight. The two ends of the first arc-shaped contact piece 64 are respectively provided with a first limiting shaft, and the two first limiting shafts respectively cooperate with the corresponding first arc-shaped hole 666 to control the first arc-shaped contact piece 64. 4. Limiting: The second sensing component 70 also includes a second mounting frame 76, a second hinge shaft, and a second limiting shaft. The second mounting frame 76 is provided with a second mounting groove 762. The two opposite side walls of the second mounting groove 762 are respectively provided with a second hinge hole 764 and a second arc-shaped hole 766. The two ends of the second arc-shaped contact piece 74 are respectively provided with a second hinge shaft. The two second hinge shafts are respectively engaged with the corresponding second hinge hole 764 so that the second arc-shaped contact piece 74 is hingedly installed in the second mounting groove 762. The second arc-shaped contact piece 74 can tilt towards the direction closer to the second work station 102 under its own weight. The two ends of the second arc-shaped contact piece 74 are respectively provided with a second limiting shaft. The two second limiting shafts are respectively engaged with the corresponding second arc-shaped hole 766 to limit the second arc-shaped contact piece 74.

[0061] In this embodiment, the structure of the second sensing component 70 is the same as or similar to that of the first sensing component 60. Two first hinge shafts are coaxially arranged, each passing through a corresponding first hinge hole 664. This arrangement allows the first arc-shaped contact piece 64 to rotate hingedly relative to the first mounting frame 66. Furthermore, since the two first limiting shafts pass through corresponding first arc-shaped holes 666, the cooperation between the first limiting shafts and the first arc-shaped holes 666 can limit the first arc-shaped contact piece 64, preventing it from getting too close to the first workstation 101 or the first photoelectric switch 62. Moreover, the first arc-shaped contact piece 64 can tilt towards the first workstation 101 under its own weight. This arrangement allows the first arc-shaped contact piece 64 to rotate towards the first photoelectric switch 62 when a fruit box is placed at the first workstation 101, triggering the first photoelectric switch 62. When the fruit box at the first station 101 is moved away, the first arc-shaped contact piece 64 can tilt towards the first station 101 under its own weight, thus returning the first arc-shaped contact piece 64 to its initial position, thereby having a resetting function. Similarly, the two second hinge shafts are coaxially arranged, and the two second hinge shafts are respectively inserted into the corresponding second hinge holes 764. This arrangement allows the second arc-shaped contact piece 74 to rotate hinged relative to the second mounting frame 76. In addition, since the two second limiting shafts are respectively inserted into the corresponding second arc-shaped holes 766, the cooperation of the second limiting shafts and the second arc-shaped holes 766 can limit the second arc-shaped contact piece 74, preventing the second arc-shaped contact piece 74 from getting too close to the second station 102 or too close to the second photoelectric switch 72. Furthermore, the second arc-shaped contact 74 can tilt towards the second workstation 102 under its own weight. This design allows the second arc-shaped contact 74 to rotate towards the second photoelectric switch 72 when a fruit box is placed at the second workstation 102, triggering the switch. When the fruit box is removed from the second workstation 102, the second arc-shaped contact 74 can tilt towards the second workstation 102 under its own weight, returning it to its initial position, thus serving a resetting function.

[0062] In one embodiment, the packing device 100 further includes an alarm component 80, and the control unit is communicatively connected to the alarm component 80. The alarm component 80 can emit an alarm sound or light alarm.
