Description

Technical Field

[0001] The present invention relates to the technical field of filling equipment, and in particular to a bag moving mechanism for a horizontal self-standing spout bag packaging machine. Background Art

[0002] With their excellent shelf presence, ease of use, and excellent content protection, stand-up spout pouches have become a mainstream packaging format for liquid, semi-liquid, and powdered products (such as beverages, dairy products, condiments, and daily necessities). In automated production, horizontal packaging equipment is widely used due to its efficient and continuous operation capabilities. In this type of equipment, the packaging process progresses horizontally, from bag feeding, opening, filling, and capping.

[0003] At the critical beginning of the horizontal packaging process (i.e., the preparatory position before the bags are transported to core processes such as bag opening and filling), there is a core technical problem that significantly affects the overall efficiency, stability and packaging quality of the equipment:

[0004] "Zero-gap" phenomenon: Due to the unique physical structure of self-supporting spout bags (with bottom support gussets, a flexible bag body, and a protruding suction nozzle) that are continuously discharged from bag feeding devices (such as silos and stacking bag feeders), two adjacent bags (especially bag N about to enter the bag opening station and its subsequent bag N+1) are prone to close contact or even nesting during high-speed, continuous conveying. This results in a lack of the necessary operating clearance between bag N and bag N+1, often resulting in a near-zero-gap state.

[0005] Regarding the horizontal movement of self-supporting spout pouches between stations, a commonly used solution in the prior art utilizes two independent ejector mechanisms that alternate with each other to move the pouch between adjacent stations. This approach presents drawbacks such as complex structure, high cost, large space requirements, and limited layout. In particular, the interaction with the pouch requires precise alignment and contact with the pouch's bottom gusset or specific edge. This requires the pouch to maintain a highly consistent and stable position at the previous station. Any deviation in the pouch's posture (e.g., tilt, twist) or positional error (e.g., insufficient forward movement, backward movement, or lateral movement) can prevent the ejector from accurately reaching the target position. During high-speed operation, ensuring that each pouch achieves the precise ejector position and posture required is extremely difficult due to variations in bag feeding, accumulated conveying errors, bag deformation (especially with flexible composite film materials), and disturbances from previous processes (e.g., bag opening). Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a bag moving mechanism for a horizontal self-supporting spout bag packaging machine.

[0007] To achieve the above-mentioned objectives, the present invention discloses a bag moving mechanism for a horizontal self-standing spout bag packaging machine, comprising an equipment frame, a bag separating device and a bag transferring device. A working slot is provided on the top of the equipment frame, and the working slot is used to support the bottom of the suction nozzle of the self-standing suction nozzle bag input into the bag device. The working slot is provided with a bag separating station, a filling station, a cleaning station and a capping station in sequence along the moving direction of the self-standing spout bag.

[0008] The bag-dividing device includes a bag-dividing frame and at least one pair of bag-dividing rods. The bag-dividing frame can be raised and lowered above the bag-dividing station. The pair of bag-dividing rods can be horizontally slidably arranged on the bag-dividing frame, and are opposite to the working slot up and down. The bag-dividing frame is driven downward by a bag-dividing lifting source to allow the pair of bag-dividing rods to be inserted into the openings of two adjacent self-standing spout bags located in the bag-dividing station, and slide to both sides of the bag-dividing frame, so that the two adjacent self-standing spout bags are slidingly spaced along the working slot.

[0009] The bag body transfer device is movably arranged above the working slot, and the bag body transfer device drives the self-standing spout bags in the working slot to translate alternately in the bag separating station, the filling station, the cleaning station, and the capping station.

[0010] Furthermore, the bag separation lifting source is fixedly arranged on the equipment frame, and a horizontal sliding translation driving source corresponding to a pair of the bag separation rods is arranged in the bag separation frame, and the translation driving source drives the bag separation rods to slide horizontally.

[0011] Furthermore, a plug-in portion is provided at the bottom end of the bag-dividing rod.

[0012] Furthermore, the outer contour of the plug-in portion is in the shape of an inverted cone.

[0013] The plug-in portion is made of soft material.

[0014] Furthermore, the bag body transfer device includes a translation plate, which is movably arranged above the working slot, and a number of receiving parts are respectively arranged on the translation plate, which are opposite to the bag dividing station, the filling station, the cleaning station, and the capping station. The translation plate is driven forward by a telescopic driving source to allow the receiving part to be inserted into the neck of the self-standing spout bag located in the working slot, and is driven by a translational power source to move horizontally along the working direction of the self-standing spout bag.

[0015] Furthermore, the bag transfer device also includes a telescopic support frame, which is movably arranged in the equipment frame, the translation plate is slidably arranged on the top of the telescopic support frame, and the telescopic driving source drives the telescopic support frame to move longitudinally.

[0016] Furthermore, the receiving portion includes a number of receiving positions corresponding to the number of the bag-dividing rods, and the receiving positions are arranged at intervals along the length direction of the translation plate.

[0017] Furthermore, the outer contour of the receiving position is semicircular, and the distance between the two receiving positions corresponds to the distance between the two self-supporting spout bags after the bag separation work is completed.

[0018] Furthermore, a conveying device is provided on the outer side of the end of the working slot, and the bag body transfer device outputs the self-standing spout bag in the capping station from the end of the working slot and places it on the conveying device, which then transports it forward to the next process.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The bag-splitting device can effectively limit the distance between two adjacent spout bags input into the packaging machine. At the same time, the bag-splitting structure cleverly utilizes the open state of the nozzle of the spout bag before filling, and sets the bag-splitting rod to cooperate with the spout bag to achieve horizontal movement.

[0021] 2. The translation plate utilizes the nozzle structure of the self-standing spout bag, and the corresponding receiving position is inserted to drag the self-standing spout bag horizontally to each workstation. The interval distance between the receiving positions on the translation plate is matched with the interval distance between the two bag-dividing rods on the bag-dividing structure, ensuring the moving distance of the self-standing spout bag and the setting distance in each workstation are accurate, further improving the work effect.

[0029] During use, the bag feeding device 4 pushes the bunch of self-standing spout bags 9 into the bag-dividing station 12 of the working slot 11 in an orderly manner. When the self-standing spout bags 9 are located in the bag-dividing station 12, the two sides above the working slot 11 are used to support the bottom of the suction nozzle on the self-standing spout bag 9.

[0030] Reference Figure 2 As shown, the bag-splitting device 2 includes a bag-splitting frame 21, at least a pair of bag-splitting rods 22, and a bag-splitting lift source 23. In this embodiment, the bag-splitting lift source 23 is a pneumatic cylinder. The bag-splitting frame 21 is movably mounted above the equipment frame 1. The bag-splitting lift source 23 is fixedly mounted on the equipment frame 1, with its movable end fixedly connected to the top of the bag-splitting frame 21. The pair of bag-splitting rods 22 are slidably mounted on the bag-splitting frame 21, and are aligned with the working channel 11 in a vertical direction.

[0031] An inserting portion 221 is provided at the bottom end of the bag-dividing inserting rod 22 . In this embodiment, the outer contour of the inserting portion 221 is in an inverted cone shape.

[0032] Furthermore, the plug-in portion 221 is made of soft material (such as silicone) to avoid damage to the opening of the self-standing spout bag.

[0033] Specifically, a pair of translation drive sources 24 corresponding to the number of the pair of bag separation rods 22 are slidably provided in the bag separation frame 21. In this embodiment, the translation drive source 24 is a driving structure such as a rodless cylinder for driving linear motion.

One end of the connecting block 25 is fixedly connected to the translation driving source 24 , and the other end of the connecting block 25 is fixedly connected to the top end of the bag dividing rod 22 .

[0035] Reference Figure 1 , reference Figure 3As shown, the bag transfer device 3 includes a translation plate 31, a telescopic support frame 32, a telescopic power source (not shown in the figure) and a translation power source 33. The telescopic support frame 32 can be moved back and forth and is arranged in the equipment frame 1. The translation plate 31 is slidably arranged on the top of the telescopic support frame 32, and it is located on the inner side above the working slot 11.

[0036] The telescopic power source is fixedly arranged on the rear side of the equipment frame 1, and its movable end is fixedly connected to the rear side of the telescopic support frame 32. The telescopic power source drives the telescopic support frame 32 to move forward and backward, so that the front side of the translation plate 31 moves to / away from the top of the working slot 11.

[0037] The translational power source 33 is arranged on the rear side of the equipment frame 1, and its movable end is fixedly connected to the top surface of the translation plate 31. The translational power source 33 drives the translation plate 31 to move horizontally back and forth along the moving direction of the self-standing spout bag 9.

[0038] In this embodiment, the bottom of the translation plate 31 and the top of the telescopic support frame 32 are slidably connected by means of a slider and a guide rail.

[0039] The telescopic driving source of this embodiment is a common driving structure commonly used to drive forward and backward movement, which will not be described here; the translational power source 33 is a common driving structure commonly used to drive horizontal movement, which will not be described here.

[0040] Reference Figure 2 、 Figure 3 As shown, the front side of the translation plate 31 is provided with a plurality of receiving portions 311 facing inward. The receiving portions 311 are spaced apart along the conveying direction of the self-standing spout pouch 9. In this embodiment, the number of receiving portions 311 corresponds to the number of workstations on the working channel 11. In the initial state, the receiving portions 311 are respectively aligned front-to-back with each workstation on the working channel 11.

[0041] The receiving portion 311 includes a plurality of receiving positions 311 - 1 . The number of the receiving positions 311 - 1 in this embodiment corresponds to the number of the bag-dividing rods 22 . Two receiving positions 311 - 1 are spaced apart along the length direction of the translation plate 31 .

[0042] The outer contour of the receiving portion 311 - 1 in this embodiment is semicircular, and the semicircular receiving portion 311 - 1 is conducive to clamping the neck of the nozzle of the self-standing spout bag 9 .

[0043] Furthermore, the distance between the two receiving positions 311 - 1 corresponds to the distance between the two self-supporting spout bags 9 after the bag-dividing device 2 has performed the bag-dividing operation.

[0044] Reference Figure 1As shown, a conveying device 8 is further provided outside the end of the working slot 11. In this embodiment, the conveying device 8 is a belt conveyor. The starting end of the conveying device 8 is located below the end of the working slot 11. The conveying device 8 is used to receive the self-supporting spout pouches 9 output from the working slot 11 and convey them forward to the next process.

[0045] The working steps of this device are:

[0046] S1. A pair of translation drive sources 24 drive a pair of bag-dividing rods 22 to move horizontally, so that they are respectively opposite to the two self-standing spout bags located in the bag-dividing station 12. Then, the bag-dividing lifting source 23 drives the bag-dividing frame 21 to move downward, so that the insertion parts 221 of the pair of bag-dividing rods 22 are respectively and simultaneously inserted into the openings of the corresponding self-standing spout bags;

[0047] S2, a pair of translation drive sources 24 moves to the left side of the bag-dividing frame 21, and then the translation drive source 24 located on the right side of the bag-dividing frame 21 moves to both sides of the bag-dividing frame 21. At this time, the moving bag-dividing rods 22 drive the self-standing spout bags to slide along the working groove 11, so as to separate and space the two self-standing spout bags that are in contact with each other, thereby meeting the working requirements of the subsequent process;

[0048] S3, the telescopic power source drives the telescopic support frame 32 to reset, so that the several receiving parts 311 on the translation plate 31 are away from the upper part of the working slot 11, and the translation power source 33 drives the translation plate 31 to reset so that the several receiving parts 311 are respectively opposite to the front and back of the bagging station 12, the filling station 13, the cleaning station 14, and the capping station 15;

[0049] S4, the telescopic power source drives the telescopic support frame 32 to move toward the working slot 11, so that the receiving position 311-1 is inserted into the neck of the nozzle of the self-standing spout bag located on the working slot 11, and then the translation power source 33 drives the translation plate 31 to move horizontally along the conveying direction of the self-standing spout bag. When the translation plate 31 moves, the self-standing spout bag on the working slot 11 is alternately moved in the bag separation station 12, the filling station 13, the cleaning station 14, and the capping station 15 in sequence;

[0050] S5. At the same time, the receiving portion 311 opposite to the capping station 15 is used to bring the self-supporting spout pouch with the capped end away from the working slot 11 to the conveying device 8.

[0051] This embodiment can effectively limit the distance between two adjacent spout bags input into the packaging machine by providing a bag dividing device 2. At the same time, the bag dividing structure cleverly utilizes the setting state of the nozzle part of the spout bag being open before the filling operation, and provides a bag dividing rod 22 to cooperate with the spout bag to realize horizontal movement. The overall structure of the bag dividing device 2 is simple and reasonable, and has the advantages of easy maintenance, stable and efficient working effect.

[0052] Furthermore, the translation plate 31 of this embodiment utilizes the nozzle structure of the self-standing spout bag, and the corresponding receiving position 311-1 is arranged to drag the self-standing spout bag horizontally to each workstation in a plug-in manner. The spacing distance between the receiving positions 311-1 on the translation plate 31 is matched with the spacing distance between the two bag-dividing insertion rods 22 on the bag-dividing structure, ensuring that the moving distance of the self-standing spout bag and the setting distance in each workstation are accurate, thereby further improving the work effect.

[0053] When filling self-supporting spout bags with high-bubble and large-capacity materials, the translation method disclosed in this embodiment can effectively reduce the supporting pressure of the equipment due to the shaking of the bag body and reduce the possibility of collision between two adjacent self-supporting spout bags to avoid leakage and material overflow (this equipment uses linear reciprocating motion, and the packaged products are not affected by centrifugal force).

[0054] Of course, the above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly. They cannot be used to limit the scope of protection of the present invention. Any modifications made based on the spirit of the main technical solution of the present invention should be included in the scope of protection of the present invention.
