Referring to fig. 4-6, the bag feeding mechanism includes a bag feeding and conveying table 400 and an opening assembly 500, wherein the bag feeding and conveying table 400 is used for receiving and directional outputting single bags transferred by the bag dragging assembly 203. The opening assembly 500 is installed at the discharge end of the bag feeding and conveying table 400 and is used for separating the mouth of the conveyed packaging bag, thereby facilitating the clamping operation of the bag feeding mechanism 300. In order to open the bag mouth and transfer the bag mouth to a filling station for automatic replacement, specifically, the bag loading mechanism 300 comprises a bag tightening arm main body 301, a first controller 302 and a second controller 303, wherein the bag tightening arm main body 301 comprises a first bag tightening arm 3011 and a second bag tightening arm 3012, and one end of the same side of the first bag tightening arm 3011 and one end of the second bag tightening arm 3012 are integrated with a clamping component 3013 capable of extending into the bag mouth of the packaging bag; that is, the bag stretching arm main body 301 is composed of two bag stretching arms arranged at intervals, and the ends of the two bag stretching arms in the same direction are provided with clamping functions, so that the bag opening of the packaging bag can be conveniently clamped, wherein the clamping component 3013 can be in the forms of clamping jaws, clamping claws, sucking discs, magnetic attraction components and the like, and the purpose is to clamp the bag opening of the packaging bag.

The first controller 302 is connected between the first bag stretching arm 3011 and the second bag stretching arm 3012, so as to change the distance between the first bag stretching arm 3011 and the second bag stretching arm 3012 along the first direction, thereby driving the bag stretching arms on the corresponding side to form a change of the distance between the bag stretching arms on the other side, so as to achieve the purpose of opening the bag mouth of the packaging bag. For example, the first and second stretching arms 3011 and 3012 are set to an initial state with a first spacing, in which the two clamping assemblies 3013 are brought into the mouth of the package, and then the distance between the first and second stretching arms 3011 and 3012 is changed to exhibit a second spacing that is greater than the first spacing, so that the two sides of the mouth can be contacted with each other to achieve the purpose of stretching and tightening the mouth. The second controller 303 is connected with the first bag stretching arm 3011 and/or the second bag stretching arm 3012, so as to equally change the positions of the first bag stretching arm 3011 and the second bag stretching arm 3012, thereby achieving the purpose of station transfer, namely representing a structural basis with automatic filling transferred to filling equipment.

Through the technical scheme, the whole packaging bag conveyor consists of three parts of the bag taking mechanism 200, the bag conveying mechanism and the bag feeding mechanism 300, and is used for respectively taking single packaging bags, adjusting and conveying the single packaging bags in a specified pose, and finally transferring the packaging bags in a bag opening expanding mode so as to achieve the purpose of automatic filling. In this embodiment, referring to fig. 2 and 3 again, the bag taking assembly 202 includes a first driving portion 2021 and a first executing portion 2022 that are in transmission connection with each other, and a first adsorbing unit 2023 for adsorbing the packaging bag is mounted on the first executing portion 2022; the first driving part 2021 inputs power to drive the first executing part 2022 to operate, so that the first adsorbing unit 2023 can change the pose to facilitate the adsorbing operation of the packaging bag.

The driving part can be an electric, pneumatic or hydraulic element as power, such as a cylinder, an oil cylinder, a motor and other servo elements capable of realizing automatic operation. The actuator is mainly an element capable of realizing linearity, steering, and/or rotation, for example, a linear drive mechanism, a multi-link rotation mechanism, a gear transmission mechanism, or the like, and any conventional combination mechanism capable of realizing the specified posture of the first suction unit 2023 may be used, and is not limited thereto.

The bag pulling assembly 203 comprises a second driving part 2031 and a second executing part 2032 which are in transmission connection with each other, wherein the second executing part 2032 is provided with a second adsorption unit 2033 for adsorbing packaging bags. Likewise, the driving part and the executing part refer to the above description, and aim to input power through the second driving part 2031 to drive the second executing part 2032 to act, so as to realize the pose change of the second adsorbing unit 2033, so as to facilitate the adsorbing operation of the packaging bag. The adsorption unit can be a flexible adsorption unit for magnetic adsorption, vacuum adsorption, adhesive adsorption or clamping adsorption, and aims to adsorb stacked packaging bags in turn, so that the uppermost packaging bag can be separated smoothly or is not adhered, and the purpose of transferring the single packaging bag to a station is achieved.

Wherein, a telescopic connection capable of moving reciprocally is formed between the first driving part 2021 and the first executing part 2022, so that the first adsorbing unit 2023 can shake the packaging bag reciprocally in a telescopic manner when adsorbing the packaging bag, thereby facilitating the second adsorbing unit 2033 to adsorb and transfer the adsorbed single packaging bag; that is, the first driving unit 2021 and the first executing unit 2022 are connected by a telescopic connection, and the telescopic connection can form reciprocal motion between the two, so that the first adsorption unit 2023 drives the packaging bag to shake reciprocally through repeated telescopic connection, and the packaging bag adhered to the lower layer can shake smoothly, thereby achieving the purpose of transferring a single packaging bag. The reciprocating telescopic connection can be realized through a linear telescopic mechanism, such as a screw rod turbine assembly, a gear rack assembly and the like; it can also be realized by a direct-connection telescopic mechanism, such as a telescopic cylinder, an electric telescopic rod and the like; it may also be realized by a multiple link assembly, for example a crank block mechanism, with the aim of forming a telescopic connection between the first driving part 2021 and the first executing part 2022, without being limited thereto.

In addition, the direction of telescopic reciprocal shake is unanimous with during operation wrapping bag stack direction to be convenient for fully shake off the wrapping bag of adhesion, shake reciprocally promptly according to wrapping bag stack direction, shake off the effect better. Through above technical scheme, can be when first adsorption unit 2023 snatchs preliminarily, through the single wrapping bag of remaining adsorbed after the reciprocal shake, the second adsorption unit 2033 of control again adsorbs the transfer, not only does not increase the occupation of land of equipment, can keep the single wrapping bag transfer operation of high efficiency moreover, compare in traditional mode that snatchs the direct wrapping bag of snatching of mechanism, can avoid appearing wrapping bag adhesion phenomenon during the transfer.

To further ensure the anti-blocking effect, in some embodiments, the novel bag taking mechanism 200 further includes a bag sucking assembly 201, where the bag sucking assembly 201 includes a third driving part 2011 and a third executing part 2012 that are in transmission connection with each other, and the third executing part 2012 is provided with a third adsorbing unit 2013 for adsorbing the packaging bag, so that the third adsorbing unit 2013 adsorbs the blocking lower packaging bag when the first adsorbing unit 2023 adsorbs the packaging bag. Through this technical scheme, can be through inhaling the third adsorption unit 2013 of bag subassembly 201 and carry out physical separation when the wrapping bag adhesion takes place, that is, first adsorption unit 2023 has adsorbed one deck or multilayer wrapping bag (generally one deck) when adsorbing the wrapping bag, control third drive portion 2011 this moment and drive the action of third executive component 2012 for third adsorption unit 2013 contacts and adsorbs the wrapping bag of lower floor, then carries out the physical separation of wrapping bag and the upper strata wrapping bag of this lower floor through the mode of whole displacement, reaches abundant anti-adhesion's purpose.

The driving part, the executing part and the adsorption unit can be used for expanding the related content configuration. However, in consideration of that the motion of the bag sucking assembly 201 and the motion of the bag taking assembly 202 form a high fit, and no motion interference occurs, in this embodiment, the third driving portion 2011 includes a first moving assembly 20111 and a second moving assembly 20112, both of which have fixed ends as mounting ends, and the motion ends as output ends, for example, a conventional linear motion mechanism or a motion mechanism converted into a linear output is adopted.

The second moving assembly 20112 is mounted at an output end of the first moving assembly 20111, and the third executing portion 2012 is mounted at an output end of the second moving assembly 20112, so that the third adsorbing unit 2013 can form an opposite acting direction with the bag taking assembly 202, that is, an opposite adsorbing direction with the first adsorbing unit 2023. That is, the third adsorbing unit 2013 and the first adsorbing unit 2023 are respectively opposite in acting force when adsorbing the package bags, so as to adapt to the position requirement that the lower package bag is separated from the uppermost package bag. And the above-mentioned motion interference is avoided by adopting a two-stage displacement mode, namely, the first moving component 20111 moves to drive the second moving component 20112 to move, and the second moving component 20112 moves to drive the third adsorbing unit 2013 to move, so that a transfer route of the first adsorbing unit 2023 when adsorbing the packaging bags from the stacking pile can be avoided well.

The movement directions of the first moving component 20111 and the second moving component 20112 may form an included angle, so as to adapt to the direction-changing movement, but in this embodiment, for example, the first moving component 20111 moves in a horizontal direction, and the second moving component 20112 moves in a vertical direction. When the adhesion of the packaging bag is detected, the first moving component 20111 and the second moving component 20112 can be controlled to act according to the front-back sequence. The detection mode may be thickness detection, weight detection, infrared interval detection, etc., but in view of simplification and effectiveness of the detection mode, in this embodiment, the novel bag taking mechanism 200 further includes a weighing sensor 2024 communicatively connected to the third driving portion 2011, where the weighing sensor 2024 is used to sense the weight of the bag absorbed by the first absorbing unit 2023, for example, the weighing sensor 2024 is disposed between the first driving portion 2021 and the first executing portion 2022 or between the first driving portion 2021 and the mounting platform, and the weight of the bag taking assembly 202 can be detected in whole or in part, so as to determine the weight of the gripped bag according to the weight change before and after the gripping, and further determine the number of the gripped bags.

On the basis of the above scheme, considering that the separation efficiency can be improved on the one hand and the buffer effect can also be carried out on the lower-layer packaging bag separated from the third adsorption unit 2013 in the process of carrying out adsorption separation on the two-layer packaging bag by the third adsorption unit 2013 and the first adsorption unit 2023, the novel packaging bag taking mechanism 200 further comprises an air blowing component 204, and an air nozzle 2041 of the air blowing component 204 is arranged between the bag taking component 202 and the packaging bag stacking station and is used for forming an air flow effect on the lower-layer packaging bag when the third adsorption unit 2013 adsorbs the adhered lower-layer packaging bag. In different embodiments, if the air tap 2041 of the air blowing component 204 is disposed between the bag taking component 202 and the bag sucking component 202, the physical separation of the two-layer packaging bag can be promoted, if the air tap 2041 of the air blowing component 204 is disposed between the bag sucking component 202 and the packaging bag stacking station, the lower-layer packaging bag separated from the third adsorption unit 2013 can be buffered, so that the third adsorption unit 2013 is smoothly separated, and the lower-layer packaging bag smoothly falls to the packaging bag stacking station, if the air tap 2041 of the air blowing component 204 can be acted on the two positions, the separation promotion and the packaging bag falling buffering can be performed.

In addition, the bag taking mechanism 200 further includes a positioning assembly 205, where the positioning assembly 205 is mounted at a bag stacking station (for example, on the mounting frame of the bag taking assembly 202 or the frame 100 of the complete machine) and is used for stacking and positioning the adhered lower-layer packaging bags after separation, that is, limiting or positioning the packaging bags when the air tap 2041 acts, so as to prevent the packaging bags from being excessively deviated from the bag stacking station in the falling process, and affect the continuous action. Of course, the positioning assembly 205 may further have a side trimming function, that is, trimming the stacking pile, so as to facilitate the accuracy of continuous grabbing operation, the side trimming structure may be that push rods capable of moving normally are disposed at two sides of the stacking pile of the packaging bag, the axial direction of the push rods is consistent with the stacking direction of the packaging bag, and when the push rods move towards the stacking pile of the packaging bag under the action of the linear motion mechanism, the edges of the stacking pile of the packaging bag are leveled.

In some embodiments, in order to perform a sufficient and stable adsorption on the uppermost packaging bag, the first adsorption units 2023 are plural, the first adsorption units 2023 are all mounted on the surface of the first execution portion 2022 near the side where the packaging bags are stacked, and the first adsorption units 2023 form an array corresponding to the corners of the packaging bags, that is, the first adsorption units 2023 adsorb the corners of the packaging bags simultaneously, so as to achieve the purpose of sufficient and stable adsorption. For example, in this embodiment, the first executing portion 2022 is a spool, the size of which matches the size of the packaging bag, the size of the spool can be changed by adjusting the two of the packaging bags corresponding to different letter types, the lower surface of each end of the spool is formed with the first adsorbing unit 2023, and the four first adsorbing units 2023 can adsorb the four corners of the packaging bag after vertical movement.

In some embodiments, the bag take-out mechanism 200 further includes a bag release assembly (not shown) for sucking and applying the top-level bag on the bag stacking station. Specifically, the bag loosening assembly comprises a fourth driving part and a fourth executing part which are in transmission connection with each other, the fourth executing part is provided with a fourth adsorption unit for adsorbing the packaging bag, power is input through the fourth driving part to drive the fourth executing part to act, so that the fourth adsorption unit can change the pose to facilitate the packaging bag adsorption operation, and the driving part, the executing part and the adsorption unit can be configured according to the related description.

On the basis of the scheme, the fourth adsorption unit is used for adsorbing the position close to the central axis of the packaging bag, so that the fourth adsorption unit and the first adsorption unit 2023 respectively act on different positions to form a larger adsorption and separation area so as to achieve a better adsorption and separation effect. Of course, in order to ensure that the adsorption/separation effect of the fourth adsorption unit and the packaging bag is more sufficient, in this embodiment, the fourth execution portion is a telescopic cylinder, such as a cylinder or an oil cylinder, which is detachably mounted on the frame 100. The fourth adsorption unit is a vacuum chuck, the vacuum chuck is mounted at the telescopic end of the telescopic cylinder, the vacuum chuck is elastic, for example, made of rubber, so that the vacuum chuck can perform elastic action when being adsorbed on the packaging bag, namely, the vacuum chuck has vacuum adsorption action on the packaging bag, and relatively obvious elastic action occurs when the vacuum chuck moves and acts on the surface of the packaging bag, so that the packaging bag has a resonance effect at the adsorbed position, and the packaging bag in the state is separated from the next layer of packaging bag more easily when being adsorbed by the first adsorption unit 2023.

In actual operation, in order to avoid the phenomenon that the first adsorption unit 2023 is easy to adhere when adsorbing the packaging bag, the bag sucking assembly 201 needs to be controlled repeatedly to act, the bag taking assembly 202 further comprises an anti-adhesion assembly 206, and the anti-adhesion assembly 206 is mounted on one side of the bag delivering and conveying table 400, which is close to the bag loosening assembly, i.e. can be in direct short-distance contact with and act on the side of the packaging bag. The anti-adhesion component 206 has an action part and a pressing part connected with each other, and the action part drives the pressing part to act when the first adsorption unit 2023 adsorbs the packaging bag, and presses down the adhered next packaging bag, especially in the range where the blowing component does not act, so as to fully and physically separate the packaging bag adhered on the lower layer in advance, so as to avoid the repeated action of the suction bag component 201.

Through above technical scheme, when the packing bag of the upper most layer forms preliminary breaking away from with next layer packing bag, intervene the effect of anti-adhesion subassembly 206, keep and lower the next layer packing bag to avoid fully breaking away from when first adsorption unit 2023 adsorbs the packing bag of the upper most layer because of the next layer packing bag of abundant adhesion. The motion part refers to a part capable of realizing straight line, steering or rotation, can realize at least two postures, keeps the pressing part not contacted with the uppermost packaging bag in the first posture, and drives the pressing part to be contacted with the next packaging bag and form pressing in the second posture. For example, the action portion is a rotating shaft, the pressing portion is a claw, the claw is integrated on a side wall of the rotating shaft, when the rotating shaft is in a first position, the claw can allow the uppermost packaging bag to pass through, when the sensor detects that the uppermost packaging bag passes through, the rotating shaft is driven to move forward and rotate along with autorotation when entering a second position, so that the claw can press the next packaging bag, and if the claw is not pressed successfully, weight detection is performed through the weighing sensor 2024, so that the purpose of driving the suction bag assembly 201 to act is achieved.

In addition, in this embodiment, in order to enable the bag pulling assembly 203 to smoothly perform station transfer on the packaging bag, especially when the station transfer distance is large, that is, the packaging bag stacking station is transferred to the bag feeding and conveying table 400, the bag pulling assembly 203 may have a corresponding structural foundation, the second driving portion 2031 is a bag pulling cylinder, the second executing portion 2032 is a rotating arm, one end of the rotating arm is hinged to the frame 100, the other end of the rotating arm is integrated with the second adsorbing unit 2033, and the second adsorbing unit 2033 may be a flexible adsorbing assembly or a rigid clamping assembly as described above, for example, by using finger cylinder clamping, the side of the packaging bag can be stably clamped and adsorbed.
