Description

TECHNICAL FIELD

[0001] The present disclosure relates to a system for taking out an article from a packaging box, and more particularly, to a system for taking out an article from a packaging box, by which a heavy article held in a packaging box having an open upper surface is taken out. BACKGROUND

[0002] As a packaging container for shipping and storing an article, a box having a cubic shape is widely used.

[0003] Figure 1 A packaging box of a widely used form is illustrated.

[0004] The packaging box 1 is mainly made of paper panels coated with a synthetic resin film, and is closed by four panels, in which the top surface and the bottom surface of the packaging box extend from the side surfaces.

[0005] Since the top surface and the bottom surface of the packaging box have the same structure, the top surface will be described. Figure 1 The four panels 2 to 5 are made in two pairs, and are folded from the edges of the side surfaces to close the upper surface when the ends of the four panels abut or are adjacent to each other. One pair of panels 4 and 5 is folded in a facing state, and then the other pair of panels 2 and 3 is folded in a facing state, and is placed in a perpendicular orientation to the previously folded pair of panels 4 and 5.

[0006] In this way, the upper surface of the packaging box is closed, and the abutting ends of the first pair of panels 2 and 3 folded and placed above are coupled to each other by a tape, and are closed to prevent the packaging box 1 from being opened by an external force.

[0007] After the packaging box 1 is first constructed to close the bottom surface in the same mode as the upper surface, and then an article is put in and held in the inner portion of the packaging box 1 from the upper surface of the packaging box, the panels 4, 5 forming the top surface are folded as described above, and the ends of the pair of panels 2 and 3 are coupled with a tape, thereby closing the packaging box 1. The closed packaging box 1 is shipped.

[0008] Meanwhile, when the packaging box 1 constructed in this way and containing an article is attempted to be opened, and then the article is taken out, the tape connecting the panels 2 and 3 to each other is cut, and then the panels 2 to 5 are all unfolded outward to open the upper surface. Then, the article held in the inner portion of the packaging box 1 is taken out.

[0009] In the case of general consumer goods held in the packing box 1, there is no special problem. However, in the case of goods used in mass production manufacturing factories, in order to take out the goods from the packing box 1 and then put the goods into the manufacturing factory, the operation of aligning and transporting the goods in a given direction is a work requiring a great amount of labor force, although it is a very simple operation, and becomes a cause of increasing manufacturing costs.

[0010] Especially in the case of goods held in the packing box 1 which are heavy in weight and easily damaged, excessive force is applied to the worker's body in the process of taking out the goods by the worker, and thus the worker can cause an industrial accident. In particular, since the worker cannot cope with the weight of the goods when taking out the goods, there can be a case in which the goods fall to the ground and are damaged.

[0011] Meanwhile, in Korean Patent Publication No. 10-1554009 (Document 1), an invention entitled "Packing box having window structure for withdrawing stick cake goods" is disclosed. The packing box according to Document 1 proposes a configuration to more easily withdraw goods held in the packing box.

[0012] However, the packing box according to the invention of Document 1 only discloses a configuration in which a consumer stores goods in the packing box and easily withdraws the goods one by one when necessary, but does not propose a configuration suitable for taking out goods from a packing box required in a mass production manufacturing factory.

[0013] In addition, in Korean Patent Publication No. 10-1527654 (Document 2), an invention entitled "Packing box for easily withdrawing products" is disclosed. The packing box according to the invention of Document 2 proposes a structure to easily withdraw goods.

[0014] However, the packing box of Document 2 only facilitates the operation of opening the packing box and withdrawing the goods, and does not propose a configuration or a device for automating the withdrawal operation.

[0015] As described above, the prior art proposes a technology to easily withdraw goods held in a packing box, and such a packing box has a special form to make the withdrawal easy. However, in the prior art, there is neither a disclosure of a system to make it possible to automatically withdraw heavy or easily damaged products from a packing box having a general configuration, nor a consideration of a system to make it possible to automatically withdraw heavy or easily damaged products from a packing box having a general configuration. SUMMARY

[0016] Technical Problem

[0017] The present disclosure aims to provide a system for taking out an article from a packaging box.

[0018] Specifically, the present disclosure aims to provide a system for automatically taking out an article from a packaging box, the upper surface of which is open.

[0019] Further, the present disclosure aims to provide a taking-out system having a configuration in which, when an article held in a packaging box is heavy and easily damaged, the article is allowed to be pulled out without using human power during the process of taking out the article, without being damaged by falling, impact, or the like.

[0020] Technical Solution

[0021] According to the present disclosure for achieving at least one of the above-mentioned objects, there is provided an article taking-out system configured to take out an article held in a packaging box, the upper surface of which is open.

[0022] The article taking-out system of the present disclosure includes:

[0023] a first stage configured to hold a packaging box, the upper surface of which is open, and to turn over the packaging box so that an article held in the packaging box falls downward; and a second stage configured to support and hold the article falling downward from the first stage.

[0024] The first stage can include a support unit configured to support the packaging box and to move the packaging box upward and downward, a box holding frame on which the support unit is installed, a linear motion frame to which the box holding frame is rotatably coupled, a main frame located on and supported by the ground, wherein the linear motion frame is coupled to and supported by the main frame to be linearly movable, and a first rotation driving device provided on the linear motion frame and configured to rotatably drive the box holding frame.

[0025] The second stage can include an article holding frame having a holding surface complementary in shape to that of the article to hold the article falling downward from the first stage, a fixed frame located on and supported by the ground, wherein the article holding frame is rotatably coupled to the fixed frame, and a second rotation driving device configured to rotate the article holding frame with respect to the fixed frame.

[0026] When the packaging box containing the articles is seated on the support unit of the first loading table, the article holding frame of the second loading table can be rotated with respect to the fixed frame so that the holding surface faces downward.

[0027] After the linear motion frame of the first loading table is linearly moved so that the open upper surface of the packaging box faces the holding surface of the article holding frame, the packaging box can be raised by the support unit so that the upper surface of the packaging box approaches or comes into contact with the holding surface.

[0028] The box holding frame of the first loading table and the article holding frame of the second loading table can be rotated with respect to the linear motion frame and the main frame, respectively, in a state in which the upper surface of the packaging box approaches or comes into contact with the holding surface, so that the position of the packaging box is turned over, and so that the articles held in the packaging box fall down to be held in the holding frame.

[0029] The operation of the article extraction system according to the configuration will be described.

[0030] The box holding frame of the first loading table is separated from the article holding frame of the second loading table. In this state, the articles are held in the box holding frame of the first loading table, and the packaging box having the open upper surface is placed in the box holding frame.

[0031] Subsequently, the article holding frame of the second loading table is rotated with respect to the fixed frame so that the holding surface faces the bottom side, and the linear motion frame is linearly moved with respect to the main frame on the first loading table so that the box holding frame is placed below the article holding frame. Accordingly, the open upper surface of the packaging box faces the holding surface of the article holding frame of the first loading table.

[0032] In this state, the packaging box is raised by the support unit so that the open top surface of the packaging box approaches or abuts against the holding surface. Then, the box holding frame of the first loading table and the article holding frame of the second loading table are rotated with respect to the linear motion frame and the main frame, respectively, so that the position of the packaging box is turned over, and the articles held in the packaging box fall down to be held in the article holding frame.

[0033] Accordingly, the articles are deviated from the packaging box, and held on the holding surface of the article holding frame. Subsequently, the support unit is moved upward or downward with the packaging box supported, moved backward from the holding surface of the article holding frame, and returned to the initial state.

[0034] As described above, the articles are extracted from the packaging box, and each of the packaging box and the articles is transported to a place to be used or a dump by a separate transport unit.

[0035] As a specific embodiment aspect of the article extraction system of the present disclosure, in the article extraction system of the present disclosure,

[0036] The support unit of the first stage can include a first plate configured to support a bottom surface of the packaging box, a first actuator configured to actuate the first plate to move upward or downward, two second plates respectively configured to compress and support opposite sides of the packaging box at opposite sides of the rotation axis of the box holding frame, a second actuator configured to actuate the second plates to approach or separate from the sides of the packaging box, a fixed plate on which the second actuator is provided, and a first actuator configured to move the fixed plate upward or downward and fixed to the box holding frame.

[0037] In addition, the packaging box in which the granules should be taken out in the article taking-out system of the present disclosure can be provided with an upper surface panel covering the upper surface.

[0038] The upper surface panel can be opened before being introduced into the article taking-out system of the present disclosure, and then folded from the upper surface, but can be an obstacle to actuation of the article taking-out system.

[0039] The support unit can be provided with a vacuum suction unit configured to suction the upper surface panel under vacuum in a state in which the upper surface panel closing the upper surface of the packaging box is unfolded from the upper surface, and maintain the unfolded state.

[0040] As an additional feature of the present disclosure, the article taking-out system of the present disclosure can be configured such that:

[0041] The box holding frame and the article holding frame can be disposed at positions facing each other, and

[0042] The rotation axis of the box holding frame and the rotation axis of the article holding frame can be parallel to each other, disposed at the same height from the ground, and perpendicular to the direction of movement of the linear motion frame with respect to the main frame. Due to the linear motion of the linear motion frame with respect to the main frame, the rotation axis of the box holding frame and the rotation axis of the article holding frame can overlap each other to form a common rotation axis.

[0043] According to this structure, only by the movement of the box holding frame linearly moving with respect to the main frame and the movement of the box holding frame and the article holding frame facing each other, the box holding frame and the article holding frame can face each other and can be rotated and flipped around the same axis.

[0044] As an additional feature of the present disclosure, the article taking-out system of the present disclosure can be configured such that:

[0045] A fourth actuator configured to drive the up-and-down movement plate to move upward and downward is provided between the holding surfaces of the article holding frame, and the up-and-down movement plate is configured to support the article and move downward when the article falls downward from the packaging box supported in the article holding frame and is handled by the article holding frame.

[0046] When the article holding frame and the box holding frame are rotated and turned together in a state in which the packaging box is disposed between the frames while facing each other, the article falls downward from the packaging box supported on the box holding frame toward the holding surface of the article holding frame.

[0047] Advantageous Effects

[0048] According to the article taking-out system, the operation of taking out the article from the packaging box is automatically performed, and does not require operation based on a worker. Therefore, the worker is prevented from performing unreasonable operation due to time delay of the worker caused by taking out a heavy article or repeated taking out of a heavy article.

[0049] Further, the article is prevented from colliding with another object or falling to the ground to suffer damage.

[0050] According to the article taking-out system of the present disclosure, the upper surface panel folded from the packaging box is allowed to be maintained in an unfolded state without becoming an obstacle that blocks the article.

[0051] During the falling of the article, in a case where a gap between the position of the article at the packaging box and the holding surface of the article holding frame is large, the article can be subjected to an impact caused by the falling. However, according to the article taking-out system of the present disclosure, when the lifting plate is contracted in a state in which the lifting plate approaches and supports the article, an impact caused by the falling does not occur when the article falls from the packaging box to the holding surface frame of the article holding frame.

[0056] Hereinafter, as details for implementing the present disclosure, the configuration and operation of the retrieval system according to the embodiment of the present disclosure will be described with reference to the accompanying drawings.

[0057] The retrieval system according to the present embodiment is configured to retrieve an article from a packaging box as illustrated in Figure 1 .

[0058] The upper surface panels 2 to 5 covering the upper surface of the packaging box 1 are all opened and unfolded, and the film roll 9 rolled into a cylindrical shape is accommodated in the space of the inner portion of the packaging box as an article to be retrieved by the retrieval system according to the present embodiment.

[0059] The film roll 9 takes the form of a roll in which a film is wound, and is very heavy. Some components of the retrieval system according to the present embodiment are configured to be suitable for retrieving the film roll 9, but the article retrieved by the retrieval system according to the present embodiment is not limited to the film roll, and thus includes all articles held within the packaging box 1 and can be detached from the packaging box 1 by turning over the packaging box 1.

[0060] Figure 2 and Figure 3 The retrieval system according to the embodiment of the present disclosure is illustrated in Figs. 1 to 3. The configuration of the retrieval system of the present disclosure will be described with reference to these drawings.

[0061] When roughly classified, the retrieval system of the present disclosure is composed of the first carrier tables 10 to 40 that turn over the packaging box 1 so as to hold the packaging box 1 in a state in which the upper surface of the packaging box is open, and the second carrier tables 50 and 60 that support and hold the film roll 9 dropped from the first carrier table 20.

[0062] Regarding the first carrier tables 10 to 40, there are provided a main frame 10 that is placed and supported on the floor and extends in a long length to be placed on the floor and fixed to the floor, a linear motion frame 20 that moves on the main frame 10 in the longitudinal direction C of the main frame 10, a box holding frame 30 that is rotatably coupled to the linear motion frame 20, and a support unit 40 that is installed on the box holding frame 30 and supports the bottom and side portions of the packaging box 1.

[0063] Regarding the second carrier tables 50 and 60, there are provided a fixed frame 50 that is placed and supported on the floor, and an article holding frame 60 that is rotatably coupled to the fixed frame 50.

[0064] The article holding frame 60 is provided with a pair of holding plates 62 disposed apart from each other in a diameter direction of the film roll 9, having a concave curved surface complementary to a cylindrical shape of the film roll 9 as a holding surface so as to accommodate the film roll 9 dropped from the package box 1 supported on the support unit 40 on the first stage 10 to 40.

[0065] First, the configuration of the first stage will be described in detail.

[0066] The main frame 10 in the first stage 10 to 40 is configured such that a plurality of pillars 11 placed on the ground are vertically disposed, and a long box-shaped cross beam 12 is integrally formed with the pillars 11 and placed at upper end portions of the pillars 11.

[0067] A screw feed unit is embedded at each of the upper surfaces of the pillars 11, and a linear motion frame 20 is engaged with a screw shaft 13 of the screw feed unit so as to linearly move in a longitudinal direction of the main frame 10 according to rotation of the screw shaft 13.

[0068] The linear motion frame 20 is configured in the shape of a box, an upper surface and a rear surface of which are open, and is disposed apart from an upper surface of the main frame 10, and a first driving motor 21 as a rotational driving device for rotating the box holding frame 30 is fixedly coupled inside the linear motion frame 20. The first driving motor 21 is composed of a servo motor whose rotational angle is controlled and a reducer which reduces output of the servo motor, and a rotational shaft of the first driving motor 21 refers to an output shaft of the reducer.

[0069] The box holding frame 30 is fixed to the rotational shaft of the first driving motor 21 and rotates according to rotation of the first driving motor 21.

[0070] The following description will be made together with FIG. 2 illustrating a longitudinal cross-sectional view of the first stage 10 to 40. Figure 4

[0071] The box holding frame 30 is composed of a first portion 31 holding the package box 1, on which the support unit 40 is installed, extending along a rotational axis A of the box holding frame 30 and having an upper surface and one side open, and a second portion 32 extending vertically upward from the portion of the box and coupled to the first driving motor 21.

[0072] In the support unit 40 in the first stage 10 to 40, a first plate 41 on which a lower surface of the package box 1 is placed is disposed on a lower surface of the first portion 31 of the box holding frame, and two first actuators 42 actuating the first plate 41 upward and downward are fixed to one side of the first portion 31 of the box holding frame 30.​

[0073] The two second plates 43 that press the opposite side portions of the packaging box 1 at the opposite side portions of the rotation axis A of the box holding frame 30 are respectively provided on the upper side portions of the side walls (32) of the first portion 31 of the box holding frame 30. The second actuators 44 that actuate the second plates 43 to approach and separate from the side portions of the packaging box 1 are provided on one of the second plates 43 in pairs in parallel and are fixed to the fixed plate 45 that is provided horizontally. Figure 4

[0074] The third actuator 46 that actuates the fixed plate 45 up and down in the vertical direction and is fixed to the box holding frame 30, and a pair of linear guides 47 that guide the up and down actuation of the fixed plate 45 and are provided in parallel with the third actuator 46 are fixed to the first portion 31 of the box holding frame 30.

[0075] The support plate 49 that surrounds the four corners of the lower surface of the packaging box 1 at the corners is provided on the first plate 41.

[0076] According to this configuration, the first plate 41 is placed on the lower surface of the first portion 31 of the box holding frame 30, supports the lower surface of the packaging box 1, is actuated up and down by the actuation of the first actuator 42, and moves the packaging box 1 up and down.

[0077] The pair of second plates 43 is provided so as to abut against the opposite side portions 5 of the packaging box 1, and is supported or separated by the extension and contraction of the second actuators 44.

[0078] The fixed plate 45 provided with the second plates 43 and the second actuators 44 is moved up and down by the third actuator 46, but is synchronized with the up and down actuation of the first plate 41 to move the packaging box 1 up and down.

[0079] In the present embodiment, the first actuator 42, the second actuator 44, and the third actuator 46 are all constituted by pneumatic cylinders and are extended and contracted. However, these actuators are not necessarily pneumatic cylinders, and any element that performs linear extension and contraction can be used.

[0080] The vacuum suction units 48 are respectively provided at the fixed plate 45 and the first plate 41. The positions at which the vacuum suction units 48 are provided are positions at which the upper surface panels 3 and 4 that are unfolded from the upper surface of the packaging box 1 when the packaging box 1 is placed are placed at the first portion 31 of the box holding frame 30.

[0081] ​When the box holding frames 30 in the first loading platforms 10 to 40 and the article holding frames 60 of the second loading platforms 50 and 60 face each other to flip the packaging box 1, the upper surface panels 3 and 4 of the packaging box are placed between the box holding frames 30 and the article holding frames 60 so as not to become obstacles blocking the machine actuation, and the vacuum suction unit 48 respectively extracts (or sucks) the upper surface panels 3 and 4 of the packaging box 1 and allows the upper surface panels 3 and 4 to remain in the unfolded state.

[0082] The longitudinal cross-sectional view of the second stages 50 and 60 will be Figure 2 and Figure 3 Together, refer to Figure 5 The configurations of the second stages 50 and 60 are described.

[0083] As the fixing frame 50 for the second loading platforms 50 and 60, there are provided pillars 52 extending perpendicularly to a bottom plate 51 placed on the ground, and crossbeams 53 placed at the upper ends of the pillars. A box-shaped motor fixing frame 54 is attached to the crossbeam 53, and a second drive motor 55 serving as a rotation drive device is provided on the inner side of the motor fixing frame 54.

[0084] The second drive motor 55 is also composed of a servo motor and a speed reducer. The rotation angle of the servo motor is controlled, and the rotation axis of the second drive motor 55 is also the output axis of the speed reducer.

[0085] The article holding frame 60 is configured in the form of a box with an upper surface and one side portion opened, and a side portion opposite to the open one side portion is coupled to a rotation shaft of the second driving motor 55 .

[0086] The article holding frame 60 is provided with a side wall 61 on the opposite side of the rotation axis B in the diameter direction, and a pair of retaining plates 62, the retaining plates 62 having a concavely curved surface complementary to the cylindrical shape of the film roll 9, and the retaining plates 62 are provided in the diameter direction from the upper end portion of the side wall 61 to the inner side portion of the article holding frame 60.

[0087] A pair of vertical movement plates 63 , fourth actuators 64 that move the respective vertical movement plates 63 upward or downward, and linear guides 65 that guide the vertical movement of the vertical movement plates 63 are provided between the holding plates 62 and on the lower surface of the article holding frame 60 .

[0088] When the film roll 9 is moved upward or downward by the fourth actuator 64 and falls from the box holding frame 30 in the first loading platform 10 to 40 to the article holding frame 60 in the second loading platform 50 and 60, the upper and lower moving plates 63 support the film roll 9 and move upward or downward to allow the film roll 9 to rest on the holding plate 62 of the article holding frame 60 while moving downward without being impacted.

[0089] Meanwhile, the rotation axis A of the case holding frame 30 in the first load table 10 to 40 and the rotation axis B of the article holding frame 60 in the second load table 50 and 60 are parallel to each other, and the case holding frame 30 is linearly moved by the linear motion of the linear motion frame 20 between a position on the plane where the case holding frame 30 is separated from the article holding frame 60 and a position where the case holding frame 30 is overlapped with the article holding frame 60.

[0090] The case holding frame 30 is rotatable in the up-down direction with respect to the article holding frame 60 between a position located below and a position located above due to the rotation caused by the first drive motor 21.

[0091] The operation of the take-out system according to the present embodiment having the aforementioned configuration will be described.

[0092] Figure 2 and Figure 3 An initial state of the take-out system is illustrated. In this state, the article holding frame 30 of the first load table is in a state where the position of the article holding frame 30 does not overlap with the position of the article holding frame 60 of the second load table 50 and 60 on the plane, and the first portion 31 is disposed below with respect to the rotation axis A of the case holding frame 30 so as to allow the packaging case to be disposed on the article holding frame 60.

[0093] Figure 6 A state in which the packaging case is introduced into the take-out system according to the present embodiment is illustrated.

[0094] In this state, the packaging case 1 is disposed and supported by a transport robot or other transport unit on the first plate 41 of the support unit 40 attached to the case holding frame 30 in the first load table 10 to 40. The support plate 49 mounted to the corner portion of the first plate 41 is used to support the packaging case 1 so that the packaging case 1 does not move on the horizontal plane.

[0095] Further, due to the extension of the second actuator 44, the second plate 43 of the support unit 40 is moved toward the packaging case 1 to abut and support the side portion 8 of the packaging case 1, and the vacuum suction unit 48 disposed on the first plate 41 and the fixed plate 45 extracts the respective upper surface panels 3 and 4 of the packaging case 1 which is open and unfolded, and fixes the upper surface panels 3 and 4 of the packaging case 1 in place.

[0096] Figure 7 A preparation step of taking out the film roll from the packaging case is illustrated.

[0097] In a state where the packaging box 1 is placed in the article holding frame 30, the linear motion frame 20 is linearly moved along the main frame 10, and the box holding frame 30 is moved in the longitudinal direction of the main frame. The rotation axis A of the box holding frame 30 and the rotation axis B of the article holding frame 60 overlap each other, and both have a common rotation axis.

[0098] Thus, in a state illustrated in FIG. 6, the box holding frame 30 of the first object table 10 to 40 is disposed below the article holding frame 60 of the second object table 50 and 60, and the article holding frame 60 is rotated by 180 degrees and faces the packaging box 1 disposed in the box holding frame 30, below which the holding plate 62 and the up-and-down motion plate 63 are disposed. Figure 7

[0099] Figure 8 FIG. 6 illustrates a step of supporting the packaging box 1 between the box holding frame 30 and the article holding frame 60.

[0100] In this step, the support unit 40 disposed in the article holding frame 30 is actuated.

[0101] The first plate 41 supporting the lower surface of the packaging box 1 and the fixed plate 45 are respectively moved upward by the first actuator 42 and the third actuator 46, and the second plate 43 supporting the side of the packaging box 1 is coupled to the fixed plate 45. Thereby, the packaging box 1 is moved toward the article holding frame 60. The up-and-down motion plate 63 disposed on the lower surface of the article holding frame 60 is moved downward by the extension operation of the fourth actuator 64.

[0102] Thus, the packaging box 1 is disposed between the box holding frame 30 and the article holding frame 60.

[0103] Figure 9 FIG. 6 illustrates a state of flipping of the article holding frame 60 and the box holding frame 30.

[0104] The box holding frame 30 and the article holding frame 60 are rotated together in one direction by an angle of 180 degrees with respect to the common rotation axes A and B, so that the article holding frame 60 is disposed below the box holding frame 30.

[0105] Thus, the film roll 9 held in the packaging box 1 which has been supported on the box holding frame 30 is supported on the holding plate 62 and the up-and-down motion plate 63 of the article holding frame 60 of the second object table 50 and 60.

[0106] In an early stage, the film roll 9 is supported by the up-and-down motion plate 63, and is supported and placed by the up-and-down motion plate 63 while the fourth actuator 64 is contracted.

[0107] ​Next, the support unit 40 on the first load table performs a contraction actuation, and the package case 1 is separated from the article holding frame 60 holding the film roll 9. Specifically, the first plate 41 and the fixing plate 45 perform a backward movement operation so that the package case 1 is in close contact with the first portion 31 of the case holding frame 30 and is separated from the article holding frame 60.

[0108] Accordingly, the film roll 9 held in the package case 1 is discharged from the package case 1 and held in the article holding frame 60.

[0109] Subsequently, the linear motion frame 20 in the first load table 10 to 40 is linearly moved along the main frame 10, and the case holding frame 30 is separated from the article holding frame 60 of the second load table 50 and 60, is rotated again at an angle of 180 degrees with respect to the linear motion frame 20, and returns to the initial state.

[0110] Only the empty package case 1 remains on the case holding frame 30 in the first load table 10 to 40, and the film roll 9 remains on the article holding frame 60 of the second load table 50 and 60.

[0111] The package case 1 and the film roll 9 are transported from the case holding frame 30 and the article holding frame 60 by a robot or other transport unit, respectively.

Claims

1. An article retrieval system for retrieving articles held in a packaging box, wherein the upper surface of the packaging box is open, the article retrieval system comprising: a first loading platform configured to overturn a packaging box to hold the packaging box with an open upper surface and allow the articles held in the packaging box to fall downward; as well as a second loading platform configured to support and hold the article dropped downward from the first loading platform; wherein the first loading platform comprises: a supporting unit configured to support the packaging box and move the packaging box upward or downward; a box holding frame, the supporting unit being mounted on the box holding frame; a linear motion frame, the box holding frame being rotatably connected to the linear motion frame; a main frame, the main frame being located and supported on the ground, wherein the linear motion frame is connected to the main frame and supported on the main frame for linear movement; and a first rotation driving device, the first rotation driving device being arranged in the linear motion frame and used to rotatably drive the box holding frame, The second loading platform includes: an article holding frame having a holding surface with a shape complementary to that of the article so as to hold the article dropped from the first loading platform; a fixed frame located and supported on the ground, wherein the article holding frame is rotatably connected to the fixed frame; and a second rotation driving device for rotating the article holding frame relative to the fixed frame. When the packaging box holding the article is placed on the support unit of the first stage, the article holding frame of the second stage is rotated relative to the fixed frame so that the holding surface faces downward. After the linear motion frame of the first stage moves linearly along the main frame so that the open upper surface of the packaging box faces the holding surface of the article holding frame of the second stage, the packaging box moves upward by the supporting unit so that the upper surface of the packaging box approaches or abuts against the holding surface, and The box holding frame of the first loading platform and the article holding frame of the second loading platform rotate relative to the linear motion frame and the main frame respectively when the upper surface of the packaging box is close to or abuts against the holding surface, so that the position of the packaging box is flipped and the articles held in the packaging box fall downward and are held in the article holding frame.

2. The article retrieval system according to claim 1, wherein: The supporting unit of the first loading platform includes a first plate for supporting the lower surface of the packaging box, a first actuator configured to actuate the first plate in an upward or downward direction, a plurality of second plates abutting opposite side portions of the packaging box on opposite sides of the rotation axis of the box holding frame, a second actuator configured to actuate the second plates to approach or separate relative to the side portions of the packaging box, a fixed plate on which the second actuator is provided, and a third actuator fixed to the box holding frame and configured to actuate the fixed plate to move the fixed plate upward or downward in a vertical direction.

3. The article retrieval system according to claim 2, wherein: The supporting unit is provided with a vacuum suction unit configured to extract the upper surface panel under a vacuum condition to allow the upper surface panel to remain in an expanded state in which the upper surface panel closing the upper surface of the packaging box is expanded from the upper surface.

4. The article retrieval system according to claim 1, wherein: The box holding frame and the article holding frame are arranged at positions facing each other, and The rotation axis of the box holding frame and the rotation axis of the article holding frame are parallel to each other, arranged at the same height from the ground, and perpendicular to the movement direction of the linear motion frame relative to the main frame, and due to the linear movement of the linear motion frame relative to the main frame, the rotation axis of the box holding frame and the rotation axis of the article holding frame overlap with each other to form a common rotation axis.

5. The article retrieval system according to claim 1, wherein: An up-and-down moving plate configured to move upward or downward and a fourth actuator configured to drive the up-and-down moving plate to move upward or downward are provided between the holding surfaces of the article holding frame, so that when the article falls downward from the packaging box supported in the box holding frame and is handled by the article holding frame, the up-and-down moving plate in a raised state supports the article and moves downward.
