Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of packaging equipment, and in particular to an automatic bag-feeding device for stand-up pouches. Background Technology
[0002] Stand-up pouches, as a common form of liquid or semi-fluid packaging, are widely used in the food, daily chemical, and pharmaceutical industries. On their filling production lines, the formed stand-up pouches are typically hung one by one on continuously running conveyor rails or hanging frames for subsequent filling, sealing, and other processes.
[0003] Currently, in most production lines, especially in small- to medium-sized production scenarios or those requiring high flexibility, the aforementioned mounting operations generally rely on manual labor. Operators need to stand beside the conveyor line, manually pick up stand-up pouches, and precisely insert or snap the hanging holes or specific parts of the pouches onto the hooks on the moving guide rails. This manual mounting method has many drawbacks: First, manual operation is inefficient, heavily reliant on the worker's skill level and physical strength, making it difficult to match the speed of high-speed automated filling and sealing sections, thus becoming a bottleneck restricting the improvement of overall production efficiency; second, prolonged repetitive operations easily lead to worker fatigue, increasing labor and management costs, and also easily causing problems such as incomplete mounting, detachment, or missed mounting due to decreased attention, affecting production continuity and product qualification rate.
[0004] Furthermore, the consistency of manual operation is poor, and uneven force or angular deviations may cause unnecessary mechanical damage to the stand-up pouches or guide rails. In addition, with the continuous rise in labor costs and the increasing demands for automation and intelligence in production, a common pre-emptive technical challenge exists in the current manual hanging operation of stand-up pouches. Because the stand-up pouches in the previous process's conveyor or collection container are usually stacked randomly, their suction nozzles are oriented randomly and haphazardly. After manually picking them up, operators must first visually judge and manually adjust the nozzle to the correct direction, ensuring it is accurately aligned with the hook or slot opening on the guide rail before hanging can be completed.
[0005] In conclusion, the traditional manual mounting method is increasingly unable to meet the needs of modern, efficient, stable, and low-cost production. Utility Model Content

[0013] Furthermore, the output end of the conveying device is provided with a stop block, and the stop block is provided with a limit photoelectric sensor. The limit photoelectric sensor is electrically connected to the transfer device. The suction nozzle of the stand-up pouch abuts against the stop block and provides an electrical signal for the transfer device to start through the limit photoelectric sensor.
[0014] Furthermore, a pair of clamping blocks are symmetrically arranged vertically on the installation station.
[0015] The top of the clamping block has a downward penetrating clamping channel, which is connected to the left side of the clamping block.
[0016] Furthermore, the width of the clamping channel is greater than the width of the bag collection guide rail.
[0017] Furthermore, clamping components are provided on the front and rear inner sides of the clamping channel, and the clamping components move to abut against the outer side of the bag collection guide rail.

[0046] The operating principle of this equipment is as follows:
[0047] 1. The stand-up pouches to be filled are conveyed to the material sorting device 1. The centrifugal force generated by the rotation of the material sorting device 1 separates the stacked stand-up pouches. The stand-up pouches in the material sorting device 1 are output individually from its output end to the conveying device 5.
[0048] 2. The conveying device 5 conveys the filling bag forward to the detection position 51. The visual detection module 22 determines the front and back of the stand-up pouch. Specifically, the stand-up pouch is in the front direction when the spout faces the bag insertion device 4, and in the back direction when it faces away.
[0049] 3. When the vision detection module 22 determines that the stand-up pouch in the detection position 51 is reversed, the air pipe 23 blows air towards the surface of the conveying device 5, thereby blowing the stand-up pouch into the recycling box 6 for reuse.
[0050] 4. The bag collection guide rail 8 is vertically embedded in the installation station 431. Specifically, the bag collection guide rail 8 is embedded in the clamping channel 451, and the clamping component 452 abuts against the front and rear sides of the bag collection guide rail 8 to limit its position.
[0051] 5. The drive module drives the rotating frame 43 to rotate, rotating the empty bag collection guide rail 8 to below the positioning frame 42. At the same time, the bag collection guide rail 8 is vertically aligned with the positioning channel 421.
[0052] 6. The upright bag is conveyed forward by the conveyor 5 until it contacts the stop block 54. Then, the transfer device 3 grabs the upright bag at the end of the conveyor 5 and moves it above the positioning frame 42 and downward, so that the suction part of the upright bag passes through the positioning channel 421 along the guide frame 422 to the bag collection guide rail 8. At the same time, the transfer device 3 resets.
[0053] 7. The movable rod of the pressing module 44 moves downward to press down the suction nozzle of the stand-up pouch, causing the stand-up pouch at the top of the bag collecting guide rail 8 to slide down, thereby completing the bag insertion process of the stand-up pouch.
[0054] Compared to existing technologies, this equipment achieves fully automated selection of stand-up pouch nozzle orientation and bag insertion, greatly reducing manual intervention. It boasts advantages such as high efficiency and stable bag insertion results, and provides a guarantee for realizing a fully automated stand-up pouch production line.
[0055] In this embodiment, the bag collection guide rail and the bag insertion rotating frame are equipped with quick-installation and quick-disassembly functions, which provides a foundation for fully automated production line operation and improves the pick-and-place speed of the bag collection guide rail.
