AI Technical Summary
[0002]目前，将包装袋送至给袋包装设备，存在以下不足，一是袋仓每次存储的袋子数量有限，需要频繁进行添加袋子的操作；二是要等出袋位的袋子被给袋机的机夹抓取后，另一个袋子才能再被输送至出袋位，上袋速度较慢，影响给袋机包装需求
[0011]采用上述技术方案后，首先，包装袋可侧立起来在立式格栅内堆叠存放，且多个立式格栅进行循环送料，相比普通袋仓结构，既方便了袋子加料，更是极大提高了袋子存储空间，从而实现能够方便更多袋子的上袋输送；其次，最为重要的是，在出袋位，设置袋口吸嘴和袋尾吸嘴同时工作使包装袋整体抬升，于是袋子在等待被给袋机的机夹抓取前，出袋位已经预留留出空间让下一个包装袋能够提前到达出袋位，进而提高上袋速度，更好满足给袋机包装需求。

Description
Technical Field
[0001] This utility model relates to a bag feeding mechanism for feeding packaging bags to a bag packaging equipment. Background Technology
[0002] Currently, there are several shortcomings in feeding packaging bags to bag-feeding packaging equipment. First, the bag hopper can only store a limited number of bags at a time, requiring frequent bag additions. Second, another bag can only be conveyed to the bag-feeding position after the bag at the bag-out position has been gripped by the bag feeder's clamp, resulting in a slow bag loading speed that affects the bag feeder's packaging needs. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bag feeding mechanism that can facilitate the feeding and conveying of more bags, improve the bag feeding speed, and better meet the packaging needs of bag feeding machines.
[0004] This utility model is implemented through the following technical solution: A side-standing horizontal bag-feeding mechanism is characterized by comprising a front bag-feeding device and a rear bag-feeding device, with a bag-transferring device between the front and rear bag-feeding devices. When the bag-transferring device is working, it transfers the packaging bags delivered by the front bag-feeding device to the rear bag-feeding device. The rear bag-feeding device includes a conveyor table driven by a conveyor motor. The conveyor table is provided with a bag-receiving position, a bag-waiting position, and a bag-exit position. The bag-waiting position is provided with a bag-blocking component, which is movably arranged. The bag-exit position is provided with a bag-blocking plate. Above the bag-exit position, a bag-mouth suction nozzle and a bag-tail suction nozzle are movably arranged, which are used to suck up and lift the two ends of the packaging bag at the bag-exit position, respectively.
[0005] The front conveyor is used for side conveying of packaging bags. It includes a support platform and multiple equidistant vertical grids located in the middle of the support platform. The vertical grids can be flipped and connected to the conveyor chain through the pivot at the bend. A side baffle is provided on one side of the support platform.
[0006] The vertical grille consists of a front grille plate and a rear grille plate with a bending angle of no more than 90 degrees. The front grille plate is in a backward-tilted upright position above the conveyor chain, while the rear grille plate overlaps the pivot of the rear vertical grille.
[0007] The bag transfer device includes an upper row of suction cups and a lower row of suction cups. The upper row of suction cups can be flexibly connected to the front suction cup seat, and the lower row of suction cups can be flexibly connected to the rear suction cup seat. The front and rear suction cup seats are reciprocally mounted on a swing seat. The swing seat is connected to the lower end of the swing arm, and the swing arm is driven by the swing arm pusher to swing.
[0008] The swing seat is equipped with a synchronous belt driven by the swing seat motor. The front suction cup seat and the rear suction cup seat are respectively connected to the two transmission sides of the synchronous belt. The movement of the front suction cup seat and the rear suction cup seat is guided by the guide rail, which is fixed on the swing seat.
[0009] The swing base is rotatably connected to the lower end of the swing arm. An adjustable rod is provided between the swing base and the swing arm. One end of the adjustable rod is connected to the swing base, and the other end is connected to the swing arm. The movement of the bag mouth suction nozzle is driven by the bag mouth suction nozzle cylinder through a four-bar linkage, and the movement of the bag tail suction nozzle is driven by the bag tail suction nozzle cylinder.
[0010] The conveyor has multiple spaced circular belts. The movement of the bag-blocking component is driven by the bag-blocking component cylinder. The head of the bag-blocking component is a hook. When the bag is blocked, the hook enters the gap between two adjacent circular belts.
[0011] After adopting the above technical solution, firstly, the packaging bags can be stacked and stored upright in the vertical grid, and multiple vertical grids can be used for cyclic feeding. Compared with the ordinary bag bin structure, this not only facilitates bag feeding but also greatly increases the bag storage space, thus enabling more bags to be loaded and transported. Secondly, and most importantly, at the bag outlet position, the bag mouth suction nozzle and the bag tail suction nozzle work simultaneously to lift the packaging bag as a whole. Thus, before the bag is grabbed by the bag feeder's clamp, the bag outlet position has reserved space to allow the next packaging bag to arrive at the bag outlet position in advance, thereby increasing the bag loading speed and better meeting the packaging needs of the bag feeder.

[0014] As shown in the figure, the side-standing horizontal bag-feeding mechanism of this utility model includes a front bag-feeding device 1 and a rear bag-feeding device 3. The front bag-feeding device 1 is used for side-standing conveying of packaging bags and includes a support platform 10 and multiple equidistant vertical grids located in the middle of the support platform 10. The vertical grids are rotatably connected to the conveyor chain 12 via a pivot 16 at the bend. The conveyor chain 12 is driven by a conveyor chain motor 11. A side baffle 17 is provided on one side of the support platform 10 to accommodate packaging bags of different lengths. An upper baffle 13 is provided above the packaging bag delivery end of the vertical grids. The upper baffle 13 makes the packaging bags... The delivered packaging bag can be adjusted vertically; the vertical grille consists of a front grille plate 14 and a rear grille plate 15 with a bending angle of no more than 90 degrees. The front grille plate 14 has a notch 141 at the top center and recesses 142 at the lower parts of both sides. The rear grille plate 15 has protruding lugs 151 at the top sides that allow it to overlap the rear vertical grille pivot. Above the conveyor chain 12, the front grille plate 14 is in a backward tilted upright state, at which time the rear grille plate 15 overlaps the pivot 16 of the rear vertical grille.
[0015] A bag transfer device 2 is provided between the front bag feeding device 1 and the rear bag feeding device 3. When the bag transfer device 2 is working, it transfers the packaging bags sent out by the front bag feeding device 1 to the rear bag feeding device 3. The bag transfer device 2 includes an upper row of suction cups 23 and a lower row of suction cups 26. The upper row of suction cups 23 can be elastically connected to the front suction cup seat 25, and the lower row of suction cups 26 can be elastically connected to the rear suction cup seat 27. The front and rear suction cup seats are reciprocally mounted on the swing seat 21. Specifically, the swing seat 21 is provided with a synchronous belt 24 driven by the swing seat motor 28. The front suction cup seat 25 and the rear suction cup seat 27 are respectively fixedly connected to the two conveying sides of the synchronous belt 24. The movement of the front suction cup seat 25 and the rear suction cup seat 27 is guided by the guide rail 22, which is fixed to the swing seat 21. In this way, when the swing seat motor 28 drives the synchronous belt 24 to move back and forth in both directions, it can drive the front suction cup seat 25 and the rear suction cup seat 27 to move back and forth. The swing seat 21 is rotatably connected to the lower end of the swing arm 52. An adjustable pull rod 53 is provided between the swing seat 21 and the swing arm 52. One end of the adjustable pull rod 53 is connected to the swing seat 21, and the other end is connected to the swing arm 52. By adjusting the length of the adjustable pull rod 53, the swing seat 21 can move at different angles, thereby enabling the upper suction cup 23 and the lower suction cup 26 to better pick up the packaging bags in the vertical grid at the packaging bag delivery end of the front bag feeding device 1. The swing arm 52 is driven to swing by a swing arm pusher, which is a swing arm push motor 20. When the swing arm push motor 20 is working, it pulls the swing arm 52 to swing by rotating the eccentric block 29 and then by connecting rod 51.
[0016] The bag delivery device 3 includes a conveyor table 30, which has multiple spaced circular belts 31. The circular belts 31 are driven by a conveyor motor. The conveyor table 30 is equipped with a bag receiving position, a bag waiting position, and a bag exit position. The bag receiving position is used to receive the packaging bags delivered by the bag transfer device 2. The bag waiting position is equipped with a bag blocking member 32, which is movably set. The movement of the bag blocking member 32 is pushed by a bag blocking member cylinder 37. The head of the bag blocking member 32 is a hook. In the bag blocking state, the hook enters the gap between two adjacent circular belts 31 to block the bag. The bag exit position is fixedly equipped with a bag blocking member. The bag plate 34 has a bag mouth suction nozzle 38 and a bag tail suction nozzle 39 movably mounted above the bag exit position. The bag mouth suction nozzle 38 is used to suck up and lift the first end of the packaging bag at the bag exit position, and the bag tail suction nozzle 39 is used to suck up and lift the last end of the packaging bag at the bag exit position, so that the bag exit position has reserved space for the next packaging bag to arrive at the bag exit position in advance before the bag is grabbed by the clamp of the bag feeder. The movement of the bag mouth suction nozzle 38 is driven by the bag mouth suction nozzle cylinder 36 through the four-bar linkage 35, and the movement of the bag tail suction nozzle 39 is driven by the bag tail suction nozzle cylinder 33.
[0017] The invention works as follows: Packaging bags are placed sideways and stacked back-to-back in a vertical grid. Both ends of the bags are supported by a support plate 10 and limited on one side by a side baffle 17. At the bag delivery end, an upper baffle 13 slightly adjusts the vertical position of the delivered bags. At this time, the stacked bags in the vertical grid are backed by their front grid plate 14, and the bottom of the foremost bag is blocked and limited by a folded edge 9 on the support plate 10. The swing arm 52 swings forward, and the upper suction cups 23 at the suction position come over to suck up the bags in the vertical grid at the bag delivery end. After suction, the swing arm 52 swings backward. During the backward swing, the upper suction cups 23 move to the other side, while the lower suction cups 26 reach their suction positions. The upper suction cups 23 then place the sucked bags onto the receiving position of the conveyor table 30, where they are conveyed by the circular belt 31. Then, the swing arm 52 swings forward again, and the lower suction cups 26 come over to suck up the bags in the vertical grid, repeating the process. As described above, the packaging bags inside the vertical grid are transferred one by one to the conveyor table. When all the packaging bags in one vertical grid are removed, the photoelectric sensor sends a signal to control the next vertical grid filled with packaging bags to reach the delivery end. When the packaging bags reach the receiving position of the conveyor table 30, the circular belt 31 conveys the packaging bags. The packaging bags are limited by the bag baffle 34 at the bag exit position, and the subsequent packaging bags are temporarily blocked by the bag baffle 32 at the bag baffle position. At this time, the bag mouth suction nozzle 38 and the bag tail... When the suction nozzle 39 operates, it sucks up the opening and tail of the bag at the bag exit position, causing the entire bag to be lifted away from the bag exit position and wait to be grabbed by the clamp of the bag feeder. Since the bag exit position has reserved space at this time, the bag blocking cylinder 37 pushes the front end of the bag blocking component 32 to rise. Thus, the next bag blocked by the bag blocking component 32 can reach the bag exit position in advance before the previous bag is grabbed by the clamp of the bag feeder. By repeating the above actions, this utility model can complete the side-standing horizontal bag loading operation.
