[0034] Example 1, refer to Appendix Figure 1-7 .

[0035] This utility model provides a side-feeding bag device, which is installed in a filling machine. The filling machine can be a machine with a filling station, or a machine with a station that cooperates with the filling station. This cooperating station can be a station before the filling station. The device can also be other equipment that requires packaging with bags. The side-feeding bag device of this utility model is preferably used in a filling machine. In this embodiment, the equipment is a filling machine, which includes a filling station and a sealing device. The filling machine is a linear conveyor type filling machine. Reference numeral 400 indicates the filling mechanism above the filling station.

[0036] The device includes a bag feeding position 300, and a bag clamping device 700 picks up a bag from the bag feeding position 300. The bag clamping device 700 is connected to a moving device 701 to transport the bag to the filling station. The device using this invention can have multiple bag feeding positions 300 arranged in a straight line along the conveying direction, and can provide multiple bags 201 simultaneously.

[0037] The bag feeding device includes a bag feeding mechanism, a horizontal bag transport mechanism, and a vertical bag transfer mechanism. The vertical bag transfer mechanism is located in the device and is equipped with a bag receiving mechanism, which is directly opposite the bag feeding position 300.

[0038] The bag feeding device has a bag inlet position 301 and a bag outlet position 302;

[0039] The bag exit position 302 corresponds to the bag receiving mechanism. Through the vertical bag moving mechanism, the bag is moved from the bag exit position 302 to the bag feeding position 300. In this embodiment, the bag exit position 302 is located below the bag feeding position 300.

[0040] The bag inlet position 301 is located on the outside side of the device (outside the side of the main frame 100 of the device). The bag supply mechanism is set to the bag inlet position 301 and can supply bags to the bag inlet position 301. The transverse bag transport mechanism is used to transport the bag 201 from the bag inlet position 301 to the bag outlet position 302. The transverse bag transport mechanism is provided with a bag limiting structure to maintain the position of the transported bag 201 on the transverse bag transport mechanism.

[0041] The bag supply mechanism is provided with multiple horizontally arranged bag guide channels 1, which are spaced at the same distance from the bag supply positions 300. Bag stacks 200 are placed in the bag guide channels 1. The bag supply mechanism also has multiple bag-retrieving robotic arms corresponding to the bag guide channels 1, which can be telescopic suction cup assemblies 2. The horizontal conveying mechanism has linear conveying sections corresponding to the bag inlet positions 301 and bag outlet positions 302. Multiple bag limiting structures are installed on the horizontal conveying mechanism, and the spacing of the bag limiting structures corresponds to the spacing of the multiple bag supply positions 300.

[0042] The vertical bag-moving mechanism is equipped with a lifting mechanism 4, which can be a vertical cylinder. The bag receiving mechanism is connected to the lifting mechanism 4, so that the bag 201 that has reached the bag exit position 302 is transported to the bag feeding position 300. The bag receiving mechanism includes a transverse groove structure, which is aligned with the bag conveying path so that the conveyed bag can enter the transverse groove 40. One side wall 41 of the transverse groove structure is a movable wall that can cooperate with the other side wall 42 to clamp the bag 21. The groove wall is provided with a clamping block corresponding to the bag exit position. The groove wall 41 can be driven by a cylinder 43. Reference numeral 44 is a lifting guide structure. The cylinder 43 is installed on the other side wall 42. When the bag 201 is conveyed into the transverse groove 40 by the transverse conveying mechanism and reaches the bag exit position 302, the cylinder 43 is activated to drive the groove wall 41 and the groove wall 42 to cooperate to clamp the bag. Then, through vertical movement, it is transported to the bag exit position 302.

[0043] The bag transport structure includes a bag support structure and a lateral conveying mechanism to enable vertical bag transport. The lateral conveying mechanism can be a belt conveyor, in which the belt 5 can be vertically arranged. In the attached drawings, reference numeral 51 indicates the drive motor of the belt conveyor.

The back support structure is, for example, a support plate 50, and the vertical belt 5 also serves as the back support for the bag. The bag feeding device has a bag transport tray 3 corresponding to the bottom of the bag 201.

[0044] The bag limiting structure is installed on the transverse conveying mechanism and can move between the bag inlet position 301 and the bag outlet position 302.

[0045] The limiting structure adopts a left and right limiting structure for the bag, such as two L-shaped components 6 on the left and right sides. After being installed on the conveyor belt, they form two left and right limiting grooves. The telescopic suction cup group 2 picks up the bag at the outlet of the storage bag guide channel 1. After retracting, the bag 201 falls between the left and right limiting grooves.

[0046] Along the bag conveying path, the bag feeding device has a bag blocking structure on the front of the bag, which can be a bag blocking rod 7 or a plate.

[0047] like Figure 6 , 7 As shown, the filling machine includes a bag clamping device and a bag opening mechanism.

The first suction element 81 and the second suction element 82 are respectively provided with suction parts 80 for suctioning both sides of the bag 201. The suction parts 80 can be air inlets or suction cups, etc. The suction parts 80 of the first suction element 81 and the second suction element 82 are grouped together, with each suction part group targeting one bag 201. This embodiment also provides a simple structure suitable for setting multiple sets of suction parts. The first suction element 81 and the second suction element 82 are both long tube structures, with multiple suction parts 80 arranged along the length of the tube.

[0048] The bag opening assembly also includes an opening and closing drive assembly. The first suction bag element 81 and the second suction bag element 82 are connected to the opening and closing drive assembly and can perform opening and closing movements. The opening and closing drive assembly is connected to a lifting mechanism, and the bag opening assembly is connected to the lifting mechanism. The lifting mechanism is a cylinder 8, which is mounted on the mounting plate 600. During the bag opening action, the first suction bag element 81 and the second suction bag element 82 first move towards the bag to suck up the bag, and then move away from the bag to open it. At the same time, the bag clamp contracts synchronously to facilitate the opening of the bag.

[0049] In this embodiment, the opening and closing drive assembly includes an opening and closing drive power 91, a common connecting rod 92, a first connecting rod 93, and a second connecting rod 94. The opening and closing drive power 91 is connected to the common connecting rod 92, driving it to rotate around an axis perpendicular to the horizontal plane. One end of the first connecting rod 93 and the second connecting rod 94 are rotatably connected to the two ends of the common connecting rod 92, respectively. The other ends of the first connecting rod 93 and the second connecting rod 94 are connected to the first connecting frame 95 and the second connecting frame 96, respectively. The first connecting frame 95 and the second connecting frame 96 are connected to the first suction bag element 81 and the second suction bag element 82, respectively. The opening and closing drive power is connected to the mounting base 9, which is provided with guide sleeves 97 and 98 that cooperate with the guide rods in the first connecting frame 95 and the second connecting frame 96. The mounting base 9 is connected to the cylinder 8.

[0050] Example 2, refer to Figure 8-11 Please also refer to Figure 6 , 7 .

[0051] In this embodiment, the transverse bag transport mechanism adopts a vacuum suction conveyor belt mechanism. The conveyor belt 5b in the vacuum suction conveyor belt mechanism is vertically arranged, and the conveyor belt 5b is equipped with a vacuum suction port 52. The vacuum suction port 52 functions as a bag limiting mechanism, adsorbing the transported bag 201 and maintaining its position on the transverse bag transport mechanism. A vacuum suction mechanism is located behind the conveyor belt. Simultaneously, the vertically arranged conveyor belt 5b and its adsorption function also serve as a rear and bottom support structure for the bag, preventing it from falling off.

[0052] The vacuum suction conveyor belt mechanism extends from the side of the frame 100 of the filling machine at one end of the bag inlet position 301. The vacuum suction conveyor belt mechanism uses the bag outlet conveyor mechanism of the online bag making equipment as its bag supply mechanism. This bag supply mechanism is connected to the end of the vacuum suction conveyor belt mechanism located at the bag inlet position 301, and supplies bags to the vacuum suction conveyor belt mechanism. The attached reference numeral 303 is a punching mechanism that cuts the two layers of plastic film into individual bags by hot-pressing and bonding. The attached reference numeral 304 is a bag pressing and leveling component.

[0053] The vertical bag-moving mechanism is equipped with a lifting mechanism 4b, which can be a cylinder. The bag receiving mechanism is connected to the lifting mechanism. The bag receiving mechanism includes a bag limiting groove directly opposite the bag feeding position 300 and a bag bottom support structure. The bag exit position 302 is located above the bag feeding position 300, and the bag receiving mechanism is located below the bag exit position 302.

[0054] The bag receiving mechanism includes a transverse groove structure and a pair of limiting grooves 42b located above the transverse groove structure. The transverse groove structure is connected to the lifting mechanism 4b. The pair of limiting grooves forms the bag limiting groove. After the bag 201 is transported to the bag exit position 302, it releases air from the corresponding vacuum suction port 52. The bag falls into the bag limiting groove and then its lower end falls into the transverse groove structure. The transverse groove structure serves as the bottom support structure of the bag.

[0055] One side wall 41b of the transverse groove structure is a movable wall that can cooperate with the other side wall 42b to clamp the bag 21. The groove wall 41b can be driven by a cylinder 43b. The other side wall 42b of the transverse groove structure is connected to a lifting mechanism 4b.

[0056] The limiting groove 45 is connected to the spacing adjustment mechanism to adjust the spacing. The spacing adjustment mechanism is installed on the groove wall 42b. The spacing adjustment mechanism can adopt a screw and nut structure 47 driven by a motor 46, wherein the nut is connected to the limiting groove.
