Technical Field

[0002] In the field of packaging technology, a movable bag collecting device is a device used to stack and organize small bags before transferring them to a larger bag for packaging. However, the mechanical configuration of existing devices results in a mismatch between the efficiency of the small bag stacking and arranging devices and the efficiency of the larger bag packaging devices. This means that the efficiency of the larger bag packaging devices is not fully utilized, resulting in low efficiency for the entire packaging process.

[0032] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] In the detailed description that follows, reference may be made to the various drawings that form part of this application and illustrate specific embodiments of the present application. In the drawings, similar reference numerals describe substantially similar components in different figures. Each specific embodiment of the present application is described below in sufficient detail to enable a person of ordinary skill in the art to implement the technical solutions of the present application. It should be understood that other embodiments may be utilized or that structural, logical, or electrical changes may be made to the embodiments of the present application.

[0034] Figure 1 FIG. 1 is a schematic diagram of the overall structure of a movable package collection device 100 according to an embodiment of the present application. Figure 1 As shown, the movable packaging device 100 includes an overall frame 101, and the overall frame 101 is equipped with one or more warehouse units. Each warehouse unit includes a buffer bin 102 and a replacement bin 103 arranged opposite each other from top to bottom to form a blanking channel. The buffer bin 102 of each warehouse unit is located at the blanking position. During the packaging process, the first packaging bag first falls into the buffer bin 102 and is then output at the discharge position of the warehouse unit through the replacement bin 103. In the embodiment of the present application, the discharge positions of more than one warehouse unit are shared, that is, the discharge positions of more than one warehouse unit are the same discharge position. The replacement bin 103 is connected to the translation mechanism 104. Under the control of the controller, the translation mechanism 104 drives the replacement bin 103 to make the more than one warehouse unit reciprocate between their respective blanking positions and the shared discharge position.

[0035] In some embodiments, optionally, a movable packaging device may include two warehouse units, wherein the replacement bin 103 can be moved in the warehouse unit. When the replacement bin 103 is located below the cache bin 102, the entrance of the replacement bin 103 corresponds to the exit of the cache bin 102, and the neatly stacked first packaging bags discharged from the cache bin 102 enter the replacement bin 103. Then, the replacement bin 103 moves horizontally to the discharge position to discharge the first packaging bags inside. After the replacement bin 103 discharges the first packaging bag, it moves horizontally back to the bottom of the cache bin 102 and then proceeds to the next delivery. The two replacement bins located on the translation mechanism 104 can alternately transport the first packaging bag of the cache bin 102 to the same discharge position under the action of the translation mechanism 104.

[0036] An embodiment of the present application proposes a movable packaging device, in which more than one bin unit can simultaneously stack first packaging bags in their respective bins, thereby improving the stacking efficiency of the first packaging bags.

[0037] In some embodiments, optionally, the discharge position is the opening of the second packaging bag of the bag-loading mechanism. The bag-loading mechanism can be understood as the large bag packaging device mentioned above. The first packaging bag can be understood as a small bag (i.e., a bag of smaller size), and the second packaging bag can be understood as a large bag (i.e., a bag of larger size). A large bag can be used to package multiple small bags. The movable bag collecting device proposed in this application can cooperate with the large bag packaging device (i.e., the bag-loading mechanism) to transport the stacked small bags to the large bag opening of the large bag packaging device, and then the large bag packaging device will perform secondary packaging on the stacked small bags to package them into large bags.

[0038] In this way, driven by the translation mechanism 104, the neatly stacked first packaging bags in multiple relay bins 103 can be discharged alternately at the same discharge position, so that the bag loading mechanism (i.e., the large bag packaging device) located below the discharge position can process the packaging bags stacked in multiple buffer bins as uninterruptedly as possible, thereby improving the utilization rate of the bag loading mechanism, and further improving the work efficiency of the bag loading mechanism and the entire packaging process.

[0039] Figure 2 This is a front view of the structure within the overall frame of a movable packaging device according to an embodiment of the present application. Figure 2As shown, the translation mechanism 104 may include: a driving source 1041, a guide bracket 1042 and a moving body 1043. The driving source 1041 is connected to the replacement bin 103 and is used to provide power for the movement of the replacement bin 103. Optionally, the driving source 1041 includes but is not limited to a cylinder, a servo motor or a hydraulic drive module. Taking the cylinder as an example, the replacement bin 103 can be pushed or pulled to move in the axial direction by filling or discharging gas into the cylinder. The guide bracket 1042 is provided with a guide rod 1044, and the moving body 1043 can be sleeved on the guide rod 1044. The moving body 1043 is connected to the replacement bin 103, and a guide wheel 1045 can be provided inside the moving body 1043, and the guide wheel 1045 moves on the guide rod 1044 along the axial direction of the guide rod 1044. In this way, under the limiting action of the guide rod 1044 and the moving body 1043, the replacement bin 103 can stably move along the extension direction (i.e., axial direction) of the guide rod 1044, preventing the replacement bin 103 from moving or shaking in the vertical direction under the action of gravity.

[0040] When the number of the relay bins 103 is two and the driving source 1041 is a cylinder, the translation mechanism 104 can be provided with four cylinders. The four cylinders are arranged in two layers, upper and lower, and two cylinders can be provided in the upper layer. The two cylinders in the upper layer can both be connected to the same relay bin 103, and the two cylinders in the upper layer can be respectively on the front and back sides of the relay bin 103. The movable rod end of the cylinder can be connected to the relay bin 103, and the cylinders on both sides drive the relay bin 103 to translate by stretching or contracting. In addition, the two cylinders in the lower layer can be connected to another relay bin 103 to provide power for the translation movement of the other relay bin 103. It should be noted that the present application does not impose any specific restrictions on the arrangement of the cylinders, as long as the relay bin can be translated.

[0041] In some embodiments, optionally, the guide wheel 1045 is provided with a groove (not shown in the figure) along 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 clamped in the groove, so that the guide wheel can roll and limit on the guide rod.

[0042] In other embodiments, the guide rod may optionally be provided with a guide rail along its axial direction, and the guide wheel may roll along the guide rail. For example, the guide rail may be a groove extending along its axial direction, and the guide wheel may be positioned within and roll along the groove. The cooperation between the guide wheel and the guide rod allows for smoother translation of the relay bin on the guide rod.

[0043] Continue to see Figure 2The buffer bin 102 may include a bin body 1021 and a secondary buffer bin plug-in mechanism. The secondary buffer bin plug-in mechanism may include a first plug-in mechanism 201 and a second plug-in mechanism 202 arranged in sequence along the blanking direction of the first packaging bag. The first plug-in mechanism 201 and the second plug-in mechanism 202 are sequentially sleeved on the bin body 1021 from top to bottom, and are respectively connected to the first plug-in mechanism 201 and the second plug-in mechanism 202. Figure 1 The overall frame 101 shown is connected. Figure 3 The functions of the first plug-in mechanism 201 and the second plug-in mechanism 202 are described in detail.

[0044] Figure 3 FIG. 1 is a schematic diagram of a buffer structure in a movable package collection device according to an embodiment of the present application. Figure 3 As shown, the first plug-in plate mechanism 201 and the second plug-in plate mechanism 202 each include two movable plug-ins 301 arranged on the same plane. The movable plug-ins 301 move through the side walls of the warehouse body 1021 to block or connect the material drop channel. The side walls are provided with slots for the plug-ins 301 to pass through. The plug-in plate mechanism 201 can move the movable plug-ins 301 horizontally via a cylinder 302. When the two movable plug-ins 301 enter the interior of the warehouse body 1021 and the distance prevents the first packaging bag from continuing to fall, the two movable plug-ins 301 are said to be in a closed state. When the two movable plug-ins 301 move toward the outside of the warehouse body 1021 and the first packaging bags located on the two movable plug-ins 301 fall, the two movable plug-ins 301 are said to be in an open state.

[0045] By setting up a plug-in plate, the first packaging bag can be cushioned when it falls into the interior of the warehouse body 1021. When a secondary plug-in plate mechanism is used, the first plug-in plate mechanism 201 is used to cushion and receive the side-by-side first packaging bags that fall from the conveyor belt, and the second plug-in plate mechanism 202 is used to cushion the first packaging bag that falls from the top to prevent the first packaging bag from undergoing significant deformation.

[0046] In some embodiments, optionally, the movable insert plate 301 can be inserted into or pulled out from both sides of the cache bin 102 through the slot.

[0047] In other embodiments, optionally, a rotating shaft is provided at one end of the movable plug plate 301, and the other end rotates along a plane with the rotating shaft as the center, and rotates in or out of the slot.

[0048] like Figure 2As shown, the spacing between the first and second latch mechanisms 201, 202 corresponds to or is not less than the thickness of a layer of first packaging bags. The thickness of the first layer of packaging bags is the thickness of the first packaging bags that land on the first latch mechanism 201. It should be noted that the spacing between the first and second latch mechanisms 201, 202 can be adjusted based on usage needs. In some embodiments, the spacing between the first and second latch mechanisms 201, 202 corresponds to the thickness of a layer of first packaging bags. The first latch mechanism 201 can be stacked with a layer of first packaging bags before the movable latch mechanism is opened, allowing the second latch mechanism 202 to receive a layer of first packaging bags. Therefore, the spacing between the first and second latch mechanisms 201, 202 can correspond to the thickness of a layer of first packaging bags. Based on this, it can be inferred that the spacing between the first and second latch mechanisms 201, 202 can also correspond to the thickness of two or more layers of first packaging bags, although this is not a limitation in this application. As long as the first packaging bags dropped when the first plate mechanism 201 is opened can be arranged smoothly on the second plate mechanism 202, the larger the spacing between the first plate mechanism 201 and the second plate mechanism 202, the more first packaging bags can be stacked on the second plate mechanism 202.

[0049] Continue to see Figure 3 ,like Figure 3 As shown, the buffer bin 102 may also include an insert mechanism 303 and a servo lifting mechanism 304, wherein the insert mechanism 303 is connected to the servo lifting mechanism 304, and the servo lifting mechanism 304 is connected to the overall frame mechanism 101. The insert mechanism 303 is sleeved on the side wall of the bin body 1021, located below the lowest plug-in plate mechanism 202, and the insert mechanism 303 is provided with two movable inserts 305 and a guide block 306 located on the same plane. The insert fingers 307 in the movable insert 305 move up and down and / or horizontally along the insert slot 309 located on the first side surface 308 of the bin body 1021, and the movable insert 305 is used to receive the first packaging bag that falls from the plug-in plate mechanism 202 in sequence. The up and down movement refers to the movement of the insert fingers 307 along the length direction of the insert slot 309; the horizontal movement refers to the insertion or extraction of the insert fingers 307 from the insert slot 309. When the strip mechanism 303 moves to the bottom of the buffer bin 102 , the movable strip 305 opens, and the multi-layer first packaging bags on the movable strip 305 are discharged from the buffer bin 102 and fall into the replacement bin 103 below.

[0050] The guide block 306 moves up and down along the slider guide rail 311 provided on the second side surface 310 of the housing 1021, and is used to limit the up and down movement of the strip mechanism 303. The servo lifting mechanism 304 is used to drive the up and down movement of the strip mechanism 303. In some embodiments, the servo lifting mechanism can optionally include a servo motor 312 and a synchronous belt 313.

[0051] Figure 4 The side of the buffer bin in a movable package collection device according to an embodiment of the present application Figure 2 A-direction structural diagram. Figure 3 and Figure 4 As shown, a synchronous belt 313 is arranged along the direction of the first packaging bag's delivery. This synchronous belt 313 includes an upper pulley 401 and a lower pulley 402. The upper pulley 401 is connected to a servo motor 312. Under the action of the servo motor 312, the synchronous belt 313 located on the pulleys begins to rotate. Because the insertion mechanism 303 is connected to the synchronous belt 313, the insertion mechanism 303 moves up and down under the action of the synchronous belt 313. The guide block on the insertion mechanism 303 moves up and down along the sliding guide rail 311, ensuring smooth and stable movement of the insertion mechanism.

[0052] The inserting fingers 307 in the insertion strip mechanism 303 can be pulled out or inserted into the warehouse body. Under the action of the cylinder 314, the two movable insertion strips 305 of the insertion strip mechanism 303 are pulled out from the interior of the warehouse body or inserted into the interior of the warehouse body. When the two movable insertion strips 305 are close to each other and can receive the fallen first packaging bag, the insertion strip mechanism 303 is in a closed state; when the two movable insertion strips 305 are away from each other and the first packaging bags are all fallen, the insertion strip mechanism 303 is in an open state.

[0053] By setting up the insertion mechanism 303, the falling of the first packaging bag in the buffer bin 102 can be controlled and stable, and the first packaging bag will not be deformed when entering the replacement bin 103 due to excessive height difference, resulting in stacking disorder.

[0054] Continue to see Figure 3 ,like Figure 3 As shown, the buffer bin 102 also includes a bag blocking mechanism 315 above its opening. The bag blocking mechanism 315 is configured with at least a movable bag blocking plate 316 for blocking first bags fed from the feed direction, allowing different first bags to be dropped side by side. The bag blocking mechanism 315 is positioned above the conveyor belt for the first bags and is provided with a movable bag blocking plate 316. When the first bags are delivered by the conveyor belt to the buffer bin 102 near its opening, they are directly thrown into the buffer bin 102 under the action of the conveyor belt. At this point, the first bags fall onto the inserting plate mechanism 201 at a position farther from the conveyor belt. The first bags then enter the buffer bin 102 near its opening and are blocked by the downwardly moving movable bag blocking plate 316. The bag blocking plate 316 then moves upward, reducing the force exerted by the conveyor belt on the first bags as they enter the opening. The first bags fall onto the inserting plate mechanism at a position closer to the conveyor belt, allowing the first bags on the inserting plate mechanism to drop side by side onto the inserting plate mechanism 201.

[0055] By providing the bag blocking mechanism, the first packaging bags can be arranged side by side when they fall onto the inserting plate mechanism 201, thereby improving the space utilization rate of the upper part of the inserting plate mechanism 201 and further improving the working efficiency of the entire warehouse unit.

[0056] In some embodiments, optionally, the moving direction of the movable baffle plate 316 is set to correspond to the feeding direction, including: a horizontal direction or a vertical direction.

[0057] In some embodiments, optionally, the cache bin may further include a photoelectric sensor, which is disposed above the plug-in plate mechanism and is configured to generate an induction signal when blocked by the first packaging bag.

[0058] The controller is electrically connected to the photoelectric sensor and is used to receive the sensing signal and calculate the number of the first packaging bags dropped onto the secondary plug-in plate mechanism of the buffer bin according to the sensing signal, and when the number of the first packaging bags on the secondary plug-in plate mechanism of the buffer bin is greater than a value, control the servo lifting mechanism to move the plug-in plate mechanism downward by a preset target distance and / or control the plug-in plate mechanism to open or close; and / or,

[0059] The controller is configured to determine, based on the sensing signal, whether the stacking height of the first packaging bags on the secondary plate mechanism of the buffer bin exceeds the height set by the photoelectric sensor on the secondary plate mechanism of the buffer bin. When the stacking height of the first packaging bags exceeds the height set by the photoelectric sensor on the secondary plate mechanism of the buffer bin, the controller controls the servo lift mechanism to move the insert mechanism downward by a preset target distance and / or controls the plate mechanism to open and close. The opening and closing of the secondary plate mechanism of the buffer bin includes opening and closing the plate within the blanking channel.

[0060] The photoelectric sensor includes an infrared sensor, among other things. When a first package bag enters the secondary plate mechanism of the buffer bin, it passes through the photoelectric sensor and then blocks it, generating a sensing signal. A controller receives this sensing signal and counts the number of first packages dropped or determines whether the stack of first packages exceeds the height set by the photoelectric sensor above the plate mechanism. The controller can determine whether to count this sensing signal toward the number of first packages or to determine the stack height of the first packages based on the duration that the first package bag blocks the photoelectric sensor. In some embodiments, a time value of 1 second can be set within the controller. If the first package bag blocks the photoelectric sensor for less than 1 second, the received sensing signal can be used to count the number of first packages. If the first package bag blocks the photoelectric sensor for more than 1 second, it can be determined that the stack height of the first packages exceeds the height set by the photoelectric sensor on the plate mechanism. Furthermore, based on whether the calculated number of first packages or the stack height exceeds the height set by the photoelectric sensor on the secondary plate mechanism of the buffer bin, the controller can determine whether to open the secondary plate mechanism of the buffer bin or move the inserting mechanism downward by a preset target distance.

[0061] By setting up a photoelectric sensor in conjunction with a controller, the embodiment of the present application can flexibly control the opening and closing of the plug-in mechanism and the up and down movement of the plug-in mechanism by setting the preset value of the first packaging bag and the height of the photoelectric sensor on the secondary plug-in mechanism of the buffer bin in the controller.

[0062] Figure 5 This is a partial schematic diagram of the replacement bin and translation mechanism of another movable packaging device according to an embodiment of the present application. Figure 5 As shown, the relay bin 103 is equipped with a two-stage relay bin insert mechanism, which includes a center insert mechanism 501 and a bottom insert mechanism 502 along the direction of the first package bag's discharge. When the relay bin 103 moves to the position corresponding to the discharge position of the buffer bin 102, the center insert mechanism 501 opens; the first package bag falls from the buffer bin 102 into the relay bin 103, and the center insert mechanism 501 closes. When the relay bin 103 moves to the discharge position, the bottom insert mechanism 502 opens, and the first package bag falls.

[0063] The first packaging bag dropped from the buffer bin can be cushioned and received by arranging the inter-bin inserting plate mechanism in the replacement bin, thereby ensuring that no significant deformation occurs in the replacement bin. In addition, the lower bin inserting plate mechanism is arranged in the replacement bin to cushion the first packaging bag dropped from the inter-bin inserting plate mechanism.

[0064] Continue to see Figure 5The middle-bin plug-in mechanism 501 and the lower-bin plug-in mechanism 502 each include two movable plug-ins 503 arranged on the same plane. The movable plug-in plates 503 move through the side walls of the bin body of the replacement bin 103 to block or connect the blanking channel. A slot 504 for the plug-in plates to pass through is provided on the side wall.

[0065] In some embodiments, optionally, the movable plug plate 503 is inserted into or pulled out from both sides of the replacement compartment 103 through the slot 504 .

[0066] In some embodiments, optionally, a rotating shaft is provided at one end of the movable plug plate 503 , and the other end rotates along a plane with the rotating shaft as the center, and rotates in or out of the slot 504 .

[0067] Combine Figure 2 and Figure 4 As shown, the movable packaging collection device further includes a position sensor connected to the translation mechanism 104 for sensing the position of the replacement bin 103; a controller connected to the position sensor for determining whether the replacement bin 103 is located below the opening of the buffer bin 102 based on the position of the replacement bin 103 sensed by the position sensor, and for controlling the driving source 1041 to drive the replacement bin 103 to translate when the first package bag lands on the in-bin inserting plate mechanism 501; and for determining whether the replacement bin 103 has translated to the discharge position. When the replacement bin 103 has translated to the discharge position, the controller controls the in-bin inserting plate mechanism 501 and the lower bin inserting plate mechanism 502 to open in sequence. When the position sensor senses that the replacement bin is located below the opening of the buffer bin, the controller controls the driving source 1041 to stop moving the replacement bin 103, and when the position sensor senses that the replacement bin 103 is at the discharge position, the controller controls the driving source 1041 to open in sequence. It should be noted that the number of position sensors can be two, one can be set at one end of the buffer bin opening corresponding to the translation mechanism, for sensing whether the replacement bin is located below the buffer bin opening, and the other can be set at the discharging position of the replacement bin corresponding to the translation mechanism, for sensing whether the replacement bin is located at the discharging position.

[0068] By setting a position sensor, the replacement bin can be accurately docked below the buffer bin opening and at the discharge position.

[0069] In some embodiments, the movable packaging collection device optionally further includes a mechanical sensor fixedly connected to the intermediate hopper mechanism for detecting mechanical changes in the intermediate hopper mechanism. A controller is electrically connected to the mechanical sensor and configured to determine whether the first packaged bag has landed on the intermediate hopper mechanism based on the mechanical changes in the intermediate hopper mechanism detected by the mechanical sensor. When the first packaged bag has landed on the intermediate hopper mechanism, the controller controls the drive source 1041 to drive the relay chamber to translate. When the relay chamber 103 translates to the discharge position, the controller controls the intermediate hopper mechanism and the lower hopper mechanism to sequentially open. A control program can be programmed in the controller to control the relay chamber's hopper mechanism power source 505 to open the intermediate hopper mechanism 501 when the relay chamber moves to the discharge position, and to control the hopper mechanism power source 505 to open the lower hopper mechanism 502 after a predetermined interval. The hopper mechanism power source can be a pneumatic cylinder, or alternatively, an air pump. The controller is also connected to the hopper mechanism to control the opening and closing of the hopper mechanism. In some embodiments, the pressure sensor can also be a photoelectric sensor, which is installed on the intermediate and lower compartment plug-in mechanisms to sense the first package bag falling onto the plug-in mechanisms. This application does not limit the type of sensor, as long as it can sense the first package bag falling onto the replacement compartment plug-in mechanism.

[0070] By setting a mechanical sensor and a controller, the moving distance of the replacement bin and the opening and closing of the middle and lower bin plug-in mechanisms can be controlled.

[0071] Continue to see Figure 2 The buffer bin may further include an interface bin 203. The interface bin 203 is funnel-shaped, and the narrow end of the interface bin 203 is fixedly connected to the upper opening of the bin body 1021. The funnel-shaped interface bin facilitates the first packaging bag to enter the bin body 1021.

[0072] In some embodiments, optionally, the photoelectric sensor is disposed 5-10 cm above the first plugboard mechanism 201 .

[0073] according to Figure 2 The working process of the movable packaging device is described in detail below. Here, the numerical threshold of the first packaging bag in the controller is set to 4, and the photoelectric sensor is set above the first plug-in mechanism 201 at a height equal to the sum of the thicknesses of the two layers of the first packaging bags, specifically 10 cm. The first packaging bag can be referred to as a small bag, and the second packaging bag can be referred to as a large bag. The initial state of the plug-in mechanism is closed.

[0074] First, the first small bag falls onto the first plug-in plate mechanism, and then the second small bag falls onto the first plug-in plate mechanism. 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 onto the first plug-in plate mechanism. At this time, there are two layers of small bags on the first plug-in plate mechanism. The photoelectric sensor sends a total of 4 sensing signals, and the controller calculates the number as 4. Moreover, because the blocking time exceeds 1s, the controller believes that the stacking height of the small bags on the plug-in plate mechanism exceeds 10cm, and then the controller controls the first plug-in plate mechanism to open, and the insertion mechanism moves down the thickness of one layer of packaging bags. At this time, two layers of small bags fall from the second plug-in plate mechanism. The controller can be set to open the second plug-in plate mechanism after the first plug-in plate mechanism is opened for more than the preset time value. Therefore, the controller controls the second plug-in plate mechanism to open, and two layers of packaging bags fall onto the insertion mechanism. During the above process, the first plug-in plate mechanism continues to receive the third, fourth, fifth, and sixth packaging bags, and two layers of small bags are formed on the first plug-in plate mechanism. Each time a layer of small bags is formed, the controller controls the insertion mechanism to move down one layer. Then the first plug-in plate mechanism opens, and the two layers of small bags fall into the second plug-in plate mechanism. Immediately, the second plug-in plate mechanism opens and falls onto the insertion mechanism. In some embodiments, when the controller determines that the height of the small bags on the first plug-in plate mechanism exceeds 10 cm, it controls the servo lifting mechanism to drive the insertion mechanism to move down 10 cm. When falling into the bottom of the buffer bin, the received multi-layer small bags are discharged to the replacement bin. After receiving the small bags, the replacement bin moves to the discharge position, opens the plug-in plate mechanism in the bin at the discharge position, and then opens the plug-in plate mechanism under the bin. Multiple layers of neatly stacked small bags fall into the large bag.

[0075] In some embodiments, two photoelectric sensors are optionally provided. One is used to enable the controller to count the number of small bags dropped into the buffer bin. When the number of small bags dropped into the buffer bin exceeds a predetermined value, the stacked small bags in the buffer bin are discharged from the buffer bin. The other is used to sense whether the stacking height of the small bags in the buffer bin exceeds a preset value. When the stacking height of the small bags exceeds the preset value, the controller controls the insertion mechanism to move downward one level at a time. During the stacking process of the small bags, the first and second insertion plate mechanisms of the buffer bin can be opened simultaneously, or can be opened and then not closed. This can reduce the problem of excessive stacking time caused by the closing and opening of the insertion plate mechanisms. For example, after two layers of small bags are stacked on the first plug-in plate mechanism, the first plug-in plate mechanism opens, and the two layers of small bags fall onto the second plug-in plate mechanism. Then, the first layer is filled with two layers of small bags. At this time, the first plug-in plate mechanism and the second plug-in plate mechanism are opened at the same time and no longer closed. Four layers of small bags fall on the top of the insertion mechanism. Then, the fifth and sixth layers of small bags fall on the insertion mechanism. The photoelectric sensor senses that the stacking height exceeds the preset value, and the controller controls the servo lifting mechanism to descend by the sum of the thickness of the two layers of small bags. Then, the seventh and sixth layers of small bags fall on the insertion mechanism. Eight layers of small bags are stacked on top of the insert mechanism. The photoelectric touch sensor again senses that its height exceeds the preset value. The controller controls the insert mechanism to move downward by the sum of the thicknesses of two layers of small bags. Then, the ninth and tenth layers of small bags are stacked on top of the insert mechanism... and the cycle continues until the number of small bags stacked meets the preset value. The controller controls the insert mechanism to open, and the stacked small bags fall into the relay bin. The relay bin moves horizontally to the discharge position. The middle and lower insert mechanisms of the bin open in turn, and the stacked small bags fall into the opening of the large bag. After the insert mechanism opens, it will close under the control of the controller and rise step by step to its initial position. During the ascent of the insert mechanism, the first and second insert plates close, and continue to receive new small bags from the first to fourth layers. When the insert mechanism rises to its initial position, the insert plates open and stacking continues.

[0076] In summary, the present application effectively increases the equipment capacity while improving the feeding speed through the provision of multiple bin units and the reciprocating motion of the replacement bin in each bin unit. The overall machine has a compact structure and high working efficiency.

[0077] The above embodiments are only used to illustrate the present application and are not intended to limit the present application. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the scope of the present application. Therefore, all equivalent technical solutions should also fall within the scope disclosed in the present application.
