As shown in fig. 3, each board inserting mechanism comprises two movable boards 301 correspondingly arranged on the same plane, and the movable boards 301 relatively reciprocate through the side wall of the bin 302 for buffering the first packaging bag entering the bin 302. Wherein, two movable plugboards 301 are arranged on the plugboard mechanism 103, the plugboards can pass through the side wall of the bin body 302 and enter the blanking passage in the bin body, the opening or closing of the plugboard mechanism 103 is completed by the two movable plugboards 301, and the two closed movable plugboards 301 are used for receiving the dropped first packaging bags. The card mechanism is provided with a power source 303 for moving power of the movable card 301.

In some embodiments, the removable inserts may alternatively be inserted into or withdrawn from opposite sides of the cache compartment 101 through slots (not shown).

With continued reference to FIG. 1, as shown in FIG. 1, the cache compartment 101 further includes a photoelectric sensor disposed above the fork strap mechanism 103 of the first stage of the multi-stage fork strap mechanism assembly for generating a sensing signal when occluded by the first package. The photoelectric sensor can also be arranged above any stage of plugboard mechanism in the multistage plugboard mechanism assembly, and the photoelectric sensor on each stage of plugboard mechanism can be used for sensing the dropped first packaging bag.

The controller is electrically connected with the photoelectric sensor and is used for receiving the induction signals, calculating the number of the first packaging bags falling onto the multi-stage plugboard mechanism assembly according to the induction signals, and controlling the plurality of plugboard mechanisms to block or communicate the blanking channels step by step when the number of the first packaging bags on the multi-stage plugboard mechanism assembly is larger than a preset value, so that the first packaging bags are uniformly stacked in the bin body of the cache bin 101; and/or the number of the groups of groups,

the controller is used for judging whether the stacking height of the first packaging bag on the multi-stage plugboard mechanism component exceeds the setting height of the photoelectric sensor on the multi-stage plugboard mechanism component according to the sensing signal, and when the stacking height of the first packaging bag exceeds the setting height of the photoelectric sensor on the multi-stage plugboard mechanism component, the plurality of plugboard mechanisms are controlled to block or communicate the blanking channels step by step, so that the first packaging bag is uniformly stacked in the bin body of the cache bin 101.

In some embodiments, the photoelectric sensor is optionally disposed 5-10cm above a first stage fork strap mechanism in the multi-stage fork strap mechanism assembly. The height of the photoelectric sensor on the first-stage plugboard mechanism can be 10cm, which is approximately equal to the thickness of two first packaging bags.

As shown in fig. 1, the number of the bin units configured in the integral frame 201 is two, wherein the cache bin 101 of each bin unit is positioned at a blanking position, and the first packaging bag falls into the cache bin 101 and is output at a discharging position of the cache bin 101 through the take-over bin 102; and the discharging positions of the two bin body units are shared. The take-over bin 102 is connected with the translation mechanism 105, and the translation mechanism 105 drives the take-over bin 102 to enable the two bin body units to reciprocate between respective blanking positions and a common discharging position. In some embodiments, optionally, one multi-stage bag-collecting device may comprise two cartridge body units, wherein the take-over cartridge 102 is movable in the cartridge body units. When the take-over bin 102 is located below the buffer bin 101, an inlet of the take-over bin 102 corresponds to an outlet of the buffer bin 101, the first packing bags which are discharged from the buffer bin 101 and are orderly stacked enter the take-over bin 102, and then the take-over bin 102 translates to a discharging position to discharge the first packing bags. After the take-over bin 102 has ejected the first package, it will translate back under the buffer bin 101, followed by the next conveyance. The two pick-up bins on the translation mechanism 105 can alternately transport the first packages of the buffer bin 101 to the same discharge position under the action of the translation mechanism 105.

The first package may be understood as a small pouch (i.e. a smaller sized pouch) and the second package may be understood as a large pouch (i.e. a larger sized pouch) in which a plurality of small pouches may be enclosed. The bag collecting device provided by the application can be matched with a large bag packaging device (namely a bag feeding mechanism), the stacked small bags are conveyed to the large bag opening of the large bag packaging device, and then the large bag packaging device is used for carrying out secondary packaging on the stacked small bags to form the large bags.

In this way, under the drive of the translation mechanism 105, the first packaging bags stacked in order in the multiple take-over bins 105 can be alternately discharged at the same discharging position, so that the bag feeding mechanism (i.e. the large bag packaging device) below the discharging position can process the packaging bags stacked in the multiple buffer bins as intermittently as possible, namely, the utilization rate of the bag feeding mechanism is improved, and the working efficiency of the bag feeding mechanism and the whole packaging process is improved.

Alternatively, drive source 1051 includes, but is not limited to, a cylinder, a servo motor, or a hydraulic drive module. Taking a cylinder as an example, the take-over chamber 103 may be pushed or pulled to move in the axial direction by, for example, charging and discharging gas into and from the cylinder. The guide bracket 1052 is provided with a guide rod 1054, and the movable body 1053 can be sleeved on the guide rod 1054.

In this way, under the limiting action of the guide rod 1054 and the moving body 1053, the take-over bin 102 can stably move along the extending direction (i.e., the axial direction) of the guide rod 1054, so that the take-over bin 102 is prevented from moving or shaking along the vertical direction under the action of gravity.

When the number of the take-over bins 102 is two and the driving source 1051 is a cylinder, the translation mechanism 105 may be provided with four cylinders. Four cylinders are divided into an upper layer and a lower layer, and two cylinders can be arranged on the upper layer. The two cylinders of the upper layer can be connected with the same take-over bin 102, and the two cylinders of the upper layer can be respectively arranged on the front side and the rear side of the take-over bin 102. The movable rod end parts of the air cylinders can be connected with the take-over bin 102, and the air cylinders on two sides drive the take-over bin 102 to translate through stretching or shrinking. In addition, two cylinders of the lower deck may be coupled to the other take-over chamber 102 to power the translational movement of the other take-over chamber 102. The arrangement of the cylinders is not particularly limited, as long as the take-over chamber can be translated.

In some embodiments, the guide wheel 1055 may optionally be provided with grooves (not shown) in the circumferential direction, the inner surface of the grooves being in contact with the outer surface of the guide bar, i.e. the guide bar may be snapped into the grooves so that the guide wheel can roll and rest on the guide bar.

For example, the guide rail may be a groove open in the axial direction, and the guide wheel may be located in the groove and roll along the groove.

The mechanical sensor is arranged to control the moving distance of the take-over bin and the opening and closing of the plugboard mechanism in the bin and the plugboard mechanism under the bin.

With continued reference to fig. 1, the cache bin may further include: an interface bin 107. The interface bin 107 is funnel-shaped, and the narrow mouth end of the interface bin 106 is fixedly connected with the upper opening of the bin body. The funnel-shaped interface bin can facilitate the first packaging bag to enter the bin body.

According to the illustration of fig. 1, the working process of the multi-stage bag collecting device will be described in detail below, wherein the numerical threshold of the first package bag in the controller is set to be 4, the photoelectric sensor is arranged above the first-stage board inserting mechanism 103 in the multi-stage board inserting mechanism assembly, the height is equal to the sum of the thicknesses of the two first package bags, specifically 10cm, the first package bag can be simply called a small package bag, the second package bag can be simply called a large package bag, the board inserting mechanism is in an initial state of being closed, the board inserting mechanism 103 at the uppermost part is in a first layer, and the second layer and the third layer are sequentially arranged from top to bottom.

The first pouch is dropped onto the fork strap mechanism 103 and then the second pouch is dropped onto the first fork strap mechanism 103, the second pouch is arranged side by side with the first pouch, and the first pouch and the second pouch form the first pouch. The third and fourth pouches are then dropped onto the first layer 103 of the fork mechanism, with two pouches on the first layer fork mechanism 103. The photoelectric sensor sends out sensing signals for 4 times in total, and the calculated number of the photoelectric sensors is 4. Moreover, because the occlusion time exceeds 1s, the controller considers the stack height of the pouches on the tucking mechanism to be more than 10cm, and then the controller controls the first layer tucking mechanism 103 to open. The two-layer small bags fall on the second-layer board inserting mechanism 103, the conveying belt continuously conveys the small bags to the first-layer board inserting mechanism 103, the controller continuously counts the small bags entering the buffer bin, when the two-layer small bags are stacked on the first-layer board inserting mechanism 103 again, the first-layer board inserting mechanism 103 and the second-layer board inserting mechanism 103 are opened and are not closed any more, at the moment, four-layer small bags are stacked on the third-layer board inserting mechanism 103, after the sixth-layer small bags are stacked on the third-layer board inserting mechanism 103, the photoelectric sensor senses that the stacking height exceeds a preset height value, the controller controls the third-layer board inserting mechanism 103 to be opened and not closed any more, six-layer small bags are stacked on the fourth-layer board inserting mechanism 103, after the eighth-layer small bags are stacked on the fourth-layer board inserting mechanism 103, the photoelectric sensor senses that the height exceeds the preset height value, then the controller controls the fourth-layer board inserting mechanism 103 to be opened and not closed any more, the five-layer small bags are stacked on the fifth-layer board inserting mechanism 103, the fifth-layer board inserting mechanism 103 is stacked up, the photoelectric sensor senses that the stacking height exceeds the preset height value, the small bags fall into the buffer bin, the fifth-layer bags fall into the buffer bin, the stack bin is opened, the small bags fall into the position of the largest bin, and the small bags are stacked in turn sequentially, and the small bags fall into the largest bin, and the position of the small bags are stacked in sequence, and the largest bin is sequentially, and then sequentially stacked in the position. After the small bags in the buffer bin 101 are discharged, the plugboard mechanism in the buffer bin 101 is restored to the initial position, and the stacking work of the small bags is continued.

In some implementations, optionally, the number of photosensors is two, one for counting the number of pouches dropped in the buffer bin 101, and when the number of pouches dropped in the buffer bin 101 exceeds a predetermined value, the stacked pouches in the buffer bin 101 are discharged from the buffer bin; the other is used for sensing whether the stacking height of the small bags in the cache bin 101 exceeds a preset value, and when the stacking height of the small bags exceeds the preset value, the controller controls the plugboard mechanism to be opened one by one.

In summary, by arranging the plurality of plugboard mechanisms in the plurality of buffering bins, the small bags can be buffered in the stacking process, and the problem of poor stacking effect caused by deformation of the packaging bags due to too high blanking channels is prevented. The multi-stage bag collecting device provided by the application enables the small bags to be stacked more attractive and tidier.

The above embodiments are provided for illustrating the present application and not for limiting the present application, and various changes and modifications may be made by one skilled in the relevant art without departing from the scope of the present application, therefore, all equivalent technical solutions shall fall within the scope of the present disclosure.
