[0034] In order to make the purposes, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0035] In the following detailed description, reference can be made to the various drawings that form a part of the present specification, which are used to illustrate specific embodiments of the present application. In the drawings, like reference numerals describe generally similar components throughout the several views. Various specific embodiments of the present application are described in sufficient detail below so as to provide a thorough understanding of the technical solutions of the present application for those with ordinary skill in the relevant art. It will be understood that other embodiments can be utilized and structural, logical, and electrical changes can be made without departing from the scope of the present application.

[0036] Figure 1 is a schematic diagram of a warehouse unit structure within the overall framework according to an embodiment of the present application. Figure 2 is a schematic diagram of an overall structure according to an embodiment of the present application. In combination with Figure 1 and Figure 2 As shown, the multi-stage bag collecting device 200 comprises an overall framework 201, and at least one warehouse unit is arranged in the overall framework 201. The warehouse unit comprises a buffer warehouse 101 and a replacement warehouse 102 arranged in correspondence from top to bottom, and the internal spaces of the two form a falling material channel. In Figure 1 and Figure 2 In the embodiment shown, two warehouse units are arranged in the overall framework 201.

[0037] The warehouse body of the buffer warehouse 101 is provided with a multi-stage plugboard mechanism assembly, which comprises one or more plugboard mechanisms 103 that are sequentially and spacedly sleeved on the outer wall of the warehouse body from top to bottom. Each plugboard mechanism 103 is fixedly connected with the overall framework, and one or more plugboard mechanisms 103 in the multi-stage plugboard mechanism assembly are controlled to move by a controller (not shown in the figure) during the process of the first packaging bag being transferred from the inlet of the buffer warehouse 101 to the outlet of the buffer warehouse 101, so as to make the falling material channel be sequentially blocked or connected, and then make the first packaging bag be uniformly stacked in the warehouse body of the buffer warehouse 101 during the falling process. Among them, the plugboard mechanisms 103 are sequentially arranged along the falling direction, and the plugboard mechanisms can be opened or closed under the control of the controller. When the plugboard mechanism 103 is opened, the stacked first packaging bag falls from the plugboard mechanism to the next stage plugboard mechanism or the replacement warehouse 102; when the plugboard mechanism 103 is closed, the first packaging bag falling from the upper plugboard mechanism falls on the plugboard mechanism of the current stage, and the falling of the first packaging bag is buffered.

[0038] By arranging a plurality of plugboard mechanisms 103 in a plurality of buffer warehouses 101, the small bags can be buffered during stacking, preventing the deformation of the packaging bags caused by the falling material channel being too high, and thus preventing the problem of poor stacking effect. The multi-stage bag collecting device 200 proposed in the present application makes the stacking of small bags more beautiful and neat.

[0039] In some embodiments, optionally, the setting interval between any two adjacent plugboard mechanisms is greater than the thickness of a first packaging bag. As Figure 1As shown, the plugboard mechanism 103 of the buffer bin 101 is sequentially the first layer, the second layer, the third layer, and so on from top to bottom. The distance between the first layer plugboard mechanism 103 and the second layer plugboard mechanism 103, the second layer plugboard mechanism 103 and the third layer plugboard mechanism 103, the third layer plugboard mechanism 103 and the fourth layer plugboard mechanism 103, and so on, is greater than the thickness of one first packaging bag. When the distance between the adjacent two plugboard mechanisms is greater than the thickness of one first packaging bag, at least one layer of first packaging bags can be stacked on the plugboard mechanism. The thickness of the first packaging bag refers to the thickness of the first packaging bag when it is full of material when falling into the multi-level packing device.

[0040] In some embodiments, optionally, the distance between any two adjacent plugboard mechanisms is set to correspond to the total thickness of two layers of first packaging bags. As shown in the figure, Figure 1 As shown, the distance between the first layer plugboard mechanism 103 and the second layer plugboard mechanism 103, the second layer plugboard mechanism 103 and the third layer plugboard mechanism 103, the third layer plugboard mechanism 103 and the fourth layer plugboard mechanism 103, and so on, is equal to the thickness of two first packaging bags. In some embodiments, optionally, the distance between any two adjacent plugboard mechanisms is adjustable. The plugboard mechanisms on the buffer bin 101 can be distributed at equal distances from the falling direction, or can be distributed in a way of equal value increasing distance, which is not limited in the present application, as long as the first packaging bags dropped by the upper plugboard mechanism can be arranged smoothly on the current plugboard mechanism, and the first packaging bags dropped by the current plugboard mechanism can be arranged smoothly on the lower plugboard mechanism. The greater the distance between the adjacent two plugboard mechanisms, the more first packaging bags can be stacked on the next level plugboard mechanism.

[0041] Figure 3 It is a schematic diagram of the overall structure of the buffer bin according to an embodiment of the present application. As shown in the figure, Figure 3 As shown, each plugboard mechanism includes two movable plugboards 301 arranged correspondingly on the same plane. The movable plugboards 301 reciprocate through the side wall of the bin body 302 for buffering the first packaging bags entering the bin body 302. The plugboard mechanism 103 is provided with two movable plugboards 301, which can pass through the side wall of the bin body 302 to enter the bin body for material falling. The opening or closing of the plugboard mechanism 103 is completed by the two movable plugboards 301, and the closed two movable plugboards 301 are used to receive the dropped first packaging bags. The plugboard mechanism is provided with a power source 303 for the movement of the movable plugboards 301.

[0042] In some embodiments, optionally, the movable plugboard is inserted or extracted from the two sides of the buffer bin 101 through a slot (not shown in the figure).

[0043] In some embodiments, optionally, one end of the movable insert plate is provided with a pivot (not shown in the figure), and the other end rotates along the plane around the pivot, rotating in or out of the slot. It should be noted that this application does not limit the movement mode of the movable insert plate, as long as it can satisfy the requirement that the insert plate mechanism can complete the open and closed states.

[0044] See also Figure 1 ,like Figure 1 As shown, the buffer compartment 101 also includes a photoelectric sensor, which is disposed above the first-stage insertion mechanism 103 of the multi-stage insertion mechanism assembly, and is used to generate a sensing signal when it is blocked by the first packaging bag. Alternatively, the photoelectric sensor can be disposed above any stage of the insertion mechanism in the multi-stage insertion mechanism assembly, and the photoelectric sensor on each stage of the insertion mechanism can be used to sense the falling first packaging bag.

[0045] The controller is electrically connected to a photoelectric sensor to receive sensing signals and calculate the number of first packaging bags falling onto the multi-stage insert mechanism assembly based on the sensing signals. When the number of first packaging bags on the multi-stage insert mechanism assembly exceeds a preset value, the controller controls multiple insert mechanisms to sequentially block or connect the material drop channels, ensuring that the first packaging bags are evenly stacked within the buffer bin 101; and / or,

[0046] The controller is used to determine whether the stacking height of the first packaging bag on the multi-stage insert mechanism assembly exceeds the set height of the photoelectric sensor on the multi-stage insert mechanism assembly based on the sensing signal, and when the stacking height of the first packaging bag exceeds the set height of the photoelectric sensor on the multi-stage insert mechanism assembly, it controls multiple insert mechanisms to block or connect the material drop channel step by step, so that the first packaging bag is evenly stacked in the buffer bin 101.

[0047] In some embodiments, the photoelectric sensor is optionally positioned 5-10 cm above the first-stage insert mechanism in the multi-stage insert mechanism assembly. The height of the photoelectric sensor on the first-stage insert mechanism can be 10 cm, approximately equivalent to the thickness of two first packaging bags.

[0048] like Figure 1As shown, the number of the warehouse units arranged in the overall frame 201 is two, wherein the buffer warehouse 101 of each warehouse unit is located at the material dropping position, and the first packaging bag is dropped into the buffer warehouse 101 and is output at the discharge position of the buffer warehouse 101 through the replacement warehouse 102; the discharge positions of the two warehouse units are shared. The replacement warehouse 102 is connected with the translation mechanism 105, and the translation mechanism 105 drives the replacement warehouse 102 to reciprocate between the respective material dropping position and the shared discharge position. In some embodiments, optionally, one multi-stage packaging device can include two warehouse units, wherein the replacement warehouse 102 can be moved in the warehouse unit. When the replacement warehouse 102 is located below the buffer warehouse 101, the inlet of the replacement warehouse 102 corresponds to the outlet of the buffer warehouse 101, and the stacked first packaging bag discharged from the buffer warehouse 101 enters the replacement warehouse 102, and then the replacement warehouse 102 is translated to the discharge position to discharge the first packaging bag inside. After the replacement warehouse 102 discharges the first packaging bag, it will be translated back to below the buffer warehouse 101 and then perform the next transportation. The two replacement warehouses located on the translation mechanism 105 can alternately transport the first packaging bag of the buffer warehouse 101 to the same discharge position under the action of the translation mechanism 105.

[0049] The multi-stage packaging device provided in the embodiments of the present application can simultaneously stack the first packaging bags in the respective warehouses, thereby improving the stacking efficiency of the first packaging bags.

[0050] In some embodiments, optionally, the discharge position is the opening of the second packaging bag of the bagging mechanism. The bagging mechanism can be understood as the above-mentioned large bag packaging device. The first packaging bag can be understood as a small bag (i.e., a bag with a smaller size), and the second packaging bag can be understood as a large bag (i.e., a bag with a larger size), and a plurality of small bags can be encapsulated in one large bag. The multi-stage packaging device provided in the present application can cooperate with the large bag packaging device (i.e., the bagging mechanism) to transport the stacked small bags to the opening of the large bag of the large bag packaging device, and then the large bag packaging device encapsulates the stacked small bags again to form a large bag.

[0051] In this way, under the driving of the translation mechanism 105, the stacked first packaging bags in the plurality of replacement warehouses 102 can be alternately discharged at the same discharge position, so that the bagging mechanism (i.e., the large bag encapsulation device) located below the discharge position can as much as possible continuously process the stacked packaging bags of the plurality of buffer warehouses, i.e., improve the utilization rate of the bagging mechanism, and thereby improve the working efficiency of the bagging mechanism and the entire packaging process.

[0052] Continuing to refer to Figure 1The translation mechanism 105 may include a drive source 1051, a guide bracket 1052, and a moving body 1053. The drive source 1051 is connected to the replacement chamber 102 and provides power for the movement of the replacement chamber 102. Optionally, the drive source 1051 may include, but is not limited to, a cylinder, a servo motor, or a hydraulic drive module. Taking a cylinder as an example, for instance, by filling the cylinder with gas, the replacement chamber 102 can be pushed or pulled to move in the axial direction. The guide bracket 1052 is provided with a guide rod 1054, and the moving body 1053 can be sleeved on the guide rod 1054. The moving body 1053 is connected to the replacement chamber 102, and a guide wheel 1055 may be provided inside the moving body 1053. The guide wheel 1055 moves along the axial direction of the guide rod 1054. In this way, under the limiting action of the guide rod 1054 and the moving body 1053, the replacement chamber 102 can move stably along the extension direction (i.e., axial direction) of the guide rod 1054, avoiding the replacement chamber 102 from moving or swaying in the vertical direction under the action of gravity.

[0053] When there are two replacement chambers 102 and the drive source 1051 is a cylinder, the translation mechanism 105 can be equipped with four cylinders. The four cylinders are arranged in two layers, with two cylinders in the upper layer. Both upper cylinders can be connected to the same replacement chamber 102, and can be located on the front and rear sides of the replacement chamber 102 respectively. The movable rod end of the cylinder can be connected to the replacement chamber 102, and the cylinders on both sides drive the replacement chamber 102 to translate by stretching or contracting. Additionally, the two lower cylinders can be connected to another replacement chamber 102, providing power for the translational movement of that other replacement chamber 102. It should be noted that this application does not impose specific restrictions on the arrangement of the cylinders, as long as it enables the translation of the replacement chamber.

[0054] In some embodiments, the guide wheel 1055 is optionally provided with a groove (not shown in the figure) in the circumferential direction, and the inner surface of the groove contacts the outer surface of the guide rod, that is, the guide rod can be locked in the groove, so that the guide wheel can roll on the guide rod and be limited.

[0055] In some other embodiments, optionally, the guide rod is provided with a guide rail in the axial direction, and the guide wheel rolls along the guide rail. For example, the guide rail can be a groove formed in the axial direction, and the guide wheel can be located in the groove and roll along the groove. The cooperation between the guide wheel and the guide rod makes the translational movement of the replacement chamber on the guide rod smoother.

[0056] Figure 4 yes Figure 1 A schematic diagram of the structure along direction A. (As shown in the diagram...) Figure 3 and Figure 4As shown, the buffer bin 101 also includes a bag-blocking mechanism 401 above its opening. The bag-blocking mechanism 401 is equipped with at least a movable bag-blocking plate 402 to block the first packaging bags entering from the feeding direction, allowing different first packaging bags to fall side by side. The bag-blocking mechanism 401 is located above the conveyor belt of the first packaging bags. The bag-blocking mechanism 401 is equipped with a movable bag-blocking plate 402 and a power source 403, which provides power for the movement of the movable bag-blocking plate 402. When the first packaging bag is conveyed by the conveyor belt to the vicinity of the buffer bin 101, the first packaging bag can be directly thrown into the buffer bin 101 under the action of the conveyor belt. At this time, the first packaging bag falls into the insertion plate mechanism 103 at a position far away from the conveyor belt. Then, the first packaging bag that is conveyed by the conveyor belt to the vicinity of the buffer bin 101 is blocked by the downward moving movable baffle plate 402. Then the movable baffle plate 402 moves upward. As a result, the force of the first packaging bag being thrown by the conveyor belt when it enters the bin is reduced, and the first packaging bag falls into the insertion plate mechanism at a position closer to the conveyor belt, so that the first packaging bags on the insertion plate mechanism can fall side by side onto the insertion plate mechanism 103.

[0057] By setting up a bag-blocking mechanism, the first packaging bags can be arranged side by side when they fall onto the insert plate mechanism 103, thereby improving the space utilization rate of the upper part of the insert plate mechanism 103 and thus improving the working efficiency of the entire warehouse unit.

[0058] In some embodiments, the moving direction of the movable baffle plate 402 may be set to correspond to the feeding direction, including: horizontal or vertical direction.

[0059] Figure 5 This is a partial structural schematic diagram of the replacement compartment and translation mechanism according to another embodiment of this application. Figure 5 As shown, the replacement bin 102 is equipped with a multi-stage insert mechanism, which includes a movable insert 503. The insert 503 is extendable from the outside of the side wall of the replacement bin 102 to the inside of the replacement bin 102, and is used to close or open the material discharge channel in the bin unit, and to buffer the first packaging bag falling into the replacement bin 102. In some embodiments, the replacement bin 102 is optionally equipped with a two-stage insert mechanism, which includes a bin-center insert mechanism 501 and a bin-bottom insert mechanism 502 in sequence along the material discharge direction of the first packaging bag. When the replacement bin 102 moves to a position corresponding to the material discharge position of the buffer bin 101, the bin-center insert mechanism 501 opens; the first packaging bag falls from the buffer bin 101 into the replacement bin 102, and the bin-center insert mechanism 501 closes. When the replacement bin 102 moves to the discharge position, the bin-bottom insert mechanism 502 opens, and the first packaging bag falls.

[0060] The first packaging bag falling from the buffer bin can be buffered and received by the bin-in-inserting-plate mechanism, so that no large deformation occurs in the replacement bin. In addition, the bin-under-inserting-plate mechanism in the replacement bin can buffer the first packaging bag falling from the bin-in-inserting-plate mechanism.

[0061] Continuing to refer to Figure 5 The bin-in-inserting-plate mechanism 501 and the bin-under-inserting-plate mechanism 502 each include two movable inserting plates 503 arranged on the same plane, and the movable inserting plates 503 move through the side wall of the bin body of the replacement bin 102 to block or connect the material falling channel, and the side wall is provided with a slot 504 for the inserting plate to pass through.

[0062] In some embodiments, the movable inserting plate 503 is optionally inserted or extracted from both sides of the replacement bin 102 through the slot 504.

[0063] In some embodiments, one end of the movable inserting plate 503 is provided with a rotating shaft, and the other end rotates around the rotating shaft along the plane and rotates into or out of the slot 504.

[0064] Continuing to refer to Figure 4 As shown in Figure 4 The movable bag collecting device further includes a position sensor connected with the translation mechanism 105 for sensing the position of the replacement bin 102, and a controller connected with the position sensor for determining whether the replacement bin 102 is located below the buffer bin 101 according to the position of the replacement bin 102 sensed by the position sensor, and controlling the driving source 1051 to drive the translation of the replacement bin 102 when the first packaging bag falls on the bin-in-inserting-plate mechanism 501, and determining whether the replacement bin 102 is translated to the material discharging position, and controlling the bin-in-inserting-plate mechanism 501 and the bin-under-inserting-plate mechanism 502 to be opened in sequence when the replacement bin 102 is translated to the material discharging position. When the position sensor senses that the replacement bin is located below the buffer bin, the controller controls the driving source 1051 to stop moving the replacement bin 102, and when the position sensor senses that the replacement bin 102 is located at the material discharging position, the bin-in-inserting-plate mechanism 501 and the bin-under-inserting-plate mechanism 502 are controlled to be opened in sequence. It should be noted that the number of position sensors can be two, one of which can be arranged at one end of the translation mechanism corresponding to the buffer bin opening for sensing whether the replacement bin is located below the buffer bin opening, and the other can be arranged at the material discharging position of the translation mechanism corresponding to the replacement bin for sensing whether the replacement bin is located at the material discharging position.

[0065] By providing the position sensor, the replacement bin can be accurately parked below the buffer bin opening and at the material discharging position.

[0066] In some embodiments, the optional set bag device further comprises a mechanical sensor (not shown in the figure) fixedly connected with the in-warehouse inserting plate mechanism, for detecting the mechanical change on the in-warehouse inserting plate mechanism. The controller is electrically connected with the mechanical sensor, for determining whether the weight of the first packaging bag dropped on the in-warehouse inserting plate mechanism meets the requirement according to the mechanical change on the in-warehouse inserting plate mechanism detected by the mechanical sensor. If the controller monitors that the weight meets a certain range, the controller controls the driving source 1051 to drive the replacement warehouse to translate, and when the replacement warehouse 102 translates to the discharging position, the controller controls the in-warehouse inserting plate mechanism and the under-warehouse inserting plate mechanism to be opened in sequence. The controller can be programmed to control the program, for controlling the replacement warehouse to open the in-warehouse inserting plate mechanism 501 by the power source 505 of the replacement warehouse inserting plate mechanism when the replacement warehouse moves to the discharging position, and opening the under-warehouse inserting plate mechanism 502 by the power source 505 after a certain interval. The controller is also connected with the inserting plate mechanism, for controlling the opening and closing of the inserting plate mechanism. In some embodiments, the mechanical sensor can also be a photoelectric sensor, which is arranged on the in-warehouse inserting plate mechanism and the under-warehouse inserting plate mechanism, for sensing the first packaging bag dropped on the inserting plate mechanism. The controller receives the photoelectric sensor signal and calculates the number or height of the first packaging bag dropped on the in-warehouse inserting plate mechanism 501, and when the number or height of the first packaging bag meets the preset value or height value, the controller controls the driving source 1051 of the translation mechanism to drive the replacement warehouse to move. The type of the sensor is not limited in the present application, as long as it can sense the stacking of the first packaging bag on the replacement warehouse inserting plate mechanism.

[0067] By arranging the mechanical sensor, the moving distance of the replacement warehouse and the opening and closing of the in-warehouse inserting plate mechanism and the under-warehouse inserting plate mechanism can be controlled.

[0068] Continuing to refer to Figure 1 , the buffer warehouse can further comprise an interface warehouse 107. The interface warehouse 107 is funnel-shaped, and the narrow end of the interface warehouse 106 is fixedly connected with the upper opening of the warehouse body. The funnel-shaped interface warehouse can facilitate the first packaging bag to enter the warehouse body.

[0069] According to the content shown in Figure 1 , the working process of the multi-stage set bag device will be described in detail below. Herein, the first packaging bag threshold value in the controller is set to 4, the photoelectric sensor is arranged above the first-stage inserting plate mechanism 103 in the multi-stage inserting plate mechanism assembly, and the setting height is equal to the sum of the thicknesses of two layers of first packaging bags, specifically 10 cm. The first packaging bag can be referred to as a small bag, and the second packaging bag is referred to as a large bag. The initial state of the inserting plate mechanism is a closed state, and the uppermost inserting plate mechanism 103 is the first layer, followed by the second layer, the third layer, and so on from top to bottom.

[0070] First, the first small bag falls on the plugboard mechanism 103, and then the second small bag falls on the first layer of the plugboard mechanism 103, and the second small bag is arranged side by side with the first small bag, and the first small bag and the second small bag constitute the first layer of small bags. Then, the third and fourth small bags fall on the first layer of the plugboard mechanism 103, and at this time, there are two layers of small bags on the first layer of the plugboard mechanism 103. The photoelectric sensor sends a total of 4 sensing signals, and the controller calculates the number to be 4. Moreover, since the shielding time exceeds 1s, the controller considers that the stacking height of the small bags on the plugboard mechanism exceeds 10cm, and immediately the controller controls the first layer of the plugboard mechanism 103 to open. Two layers of small bags fall on the second layer of the plugboard mechanism 103, and the conveying belt continues to convey the small bags to the first layer of the plugboard mechanism 103, and the controller continues to count the small bags entering the buffer bin. When two layers of small bags are stacked on the first layer of the plugboard mechanism 103 again, the first layer of the plugboard mechanism 103 and the second layer of the plugboard mechanism 103 open and no longer close. At this time, four layers of small bags are stacked on the third layer of the plugboard mechanism 103, and when the sixth layer is stacked on the third layer of the plugboard mechanism 103, the photoelectric sensor senses that the stacking height exceeds the preset height value, and the controller controls the third layer of the plugboard mechanism 103 to open and no longer close. Six layers of small bags are stacked on the fourth layer of the plugboard mechanism 103, and then when the eighth layer of small bags is stacked on the fourth layer of the plugboard mechanism 103, the photoelectric sensor senses that the height exceeds the preset height value, and immediately the controller controls the fourth layer of the plugboard mechanism 103 to open and no longer close. Eight layers of small bags are stacked on the fifth layer of the plugboard mechanism 103, and then when the fifth layer of the plugboard mechanism 103 continues to stack until the tenth layer of small bags is stacked above, the photoelectric sensor senses that the stacking height of the small bags on the fifth layer of the plugboard mechanism 103 exceeds the preset height value, and immediately the controller controls the fifth layer of the plugboard mechanism 103 to open. In turn, until the last plugboard mechanism is opened, the neatly stacked small bags fall into the replacement bin, and then the replacement bin 102 translates to the discharge position, and then the plugboard mechanism 501 in the bin and the plugboard mechanism 502 below the bin are opened in turn, and the neatly stacked small bags fall into the large bag. When the small bags in the buffer bin 101 are discharged, the plugboard mechanism in the buffer bin 101 returns to the initial position and continues to stack the small bags.

[0071] In some embodiments, optionally, the number of photoelectric sensors is two, one is used to calculate the number of small bags falling into the buffer bin 101, and when the number of small bags falling into the buffer bin 101 exceeds the predetermined value, the small bags stacked in the buffer bin are discharged from the buffer bin; and the other is used to sense whether the stacking height of the small bags in the buffer bin 101 exceeds the preset value, and when the stacking height of the small bags exceeds the preset value, the controller controls the plugboard mechanism to open level by level.

[0072] In summary, the application can make the small bags get buffering in the stacking process by setting multiple plugboard mechanisms in multiple cache bins, prevent the packaging bag from deforming due to the too high falling material channel, and further cause the problem of poor stacking effect. The multi-stage bag collecting device makes the stacking of small bags more beautiful and neat.

[0073] The above embodiments are only used to illustrate the application, and are not intended to limit the application. Those skilled in the art can make various changes and modifications without departing from the scope of the application. Therefore, all equivalent technical solutions shall belong to the scope of the present application.
