[0035] The technical solution of the present invention will be described in detail below using examples.

[0036] like Figures 1-3 The diagram shows a double-outlet bag-handling structure for a bag-making machine. This structure is installed in the gathering and bundling stage of the bag-making process to gather and arrange the hot-sealed and cooled packaging bags. It includes at least a rotating bag-stacking device 3, a bag-shaking device 4, a lifting bag-stacking device, a rotating bag-flipping device 6, and a clamping device 7, wherein:

[0037] The rotating bag stacking device 3 is used to stack the packaging bags to be collected, and includes at least a rotating shaft 30 and a stacking frame 31, the stacking frame 31 rotating about the rotating shaft 30 as the axis;

[0038] The bag shaking device 4 is set on the side of the stacking rack 31 near the bag inlet of the packaging bag 1, and includes at least a shaking rod 40 and a shaking plate 41. The shaking rod 40 is connected to the shaking plate 41, and the shaking plate 40 is close to the stacking rack 31. The shaking of the shaking rod 40 pushes the packaging bags 1 to be collected on the stacking rack 31 to complete the stacking.

[0039] The lifting and stacking device is located below the rotating and stacking device 3 and is used to carry the stacked packaging bags 1 to be collected. It includes at least a lifting platform 50 and a lifting control mechanism. The lifting control mechanism controls the up and down movement of the lifting platform 50 to move the packaging bags 1 to be collected out of the stacking area.

[0040] The rotating bag-turning device 6 is located downstream of the lifting and stacking bag device and outside the lowered lifting and stacking bag device. It is used to transfer the removed packaging bag 1 to the clamping device 7. It includes at least a turning table 61 and a turning frame 60. The turning table 61 is located outside the turning frame 60 and is used to carry the packaging bag 1 to be transferred by the turning frame 60.

[0041] The clamping device 7 is located downstream of the rotating bag-turning device 6 and is used to clamp the packaging bag 1 to be collected on the turning table 61 and tie it onto the strapping device.

[0042] Based on the above structure, this embodiment describes the structure of the double-outlet bag sorting machine in detail through the following structure.

[0043] The double-out bag arranging machine is installed on the bag making machine frame 2, specifically on the last process of gathering and bundling the packaging bags 1. The bag making machine at least includes a packaging bag conveying device for conveying the cut packaging bags 1 to the gathering and bundling process. Generally, the bag making machine packaging bag conveying device adopts a belt conveying device 20. In this embodiment, the belt conveying device 20 is divided into two parts. With the packaging bag conveying direction (the direction indicated by the arrow in the figure) as the reference, one part is the conveying part of all packaging bags, and the other part is the conveying part of qualified packaging bags. The two parts of the belt conveying device have a waste bag outlet 23. The waste bag outlet 23 is the outlet for unqualified packaging bags. That is, the processed packaging bags are sorted at this outlet, and the qualified packaging bags 1 are output. Above the waste bag outlet 23 is a bag blocking device 21. When an unqualified packaging bag is detected, the bag blocking device 21 is controlled by the control system of the bag making machine to press down the unqualified waste bag, so that the waste bag is discharged from the waste bag outlet 23. The qualified product automatically passes through the outlet and enters the qualified packaging bag conveying part. A cover 22 is provided outside the bag making machine frame 2 for dust prevention and aesthetics. The main structure of the double-out bag arranging machine is located inside the cover 22.

[0044] In this embodiment, the rotating stacking device 3 is installed at the tail end of the belt conveying device 20. The stacking rack 31 of the rotating stacking device 3 includes at least two stacking surfaces, and the two stacking surfaces are arranged at a right angle with the rotation shaft 30 as the center. Among the stacking surfaces arranged at a right angle, the stacking surface in the horizontal position faces one side of the belt conveying device 20, and is used to carry and stack the packaging bags 1 to be gathered. The stacking surface in the vertical direction serves as a baffle for the bag shaking device 4 to shake and arrange the bags.

[0045] Generally, the height of the stacking surface in the horizontal position on the stacking rack 31 is lower than the horizontal plane of the belt conveying device 20, and the height difference between the two is equivalent to the height of the packaging bags 1 to be carried. It needs to be explained that, since the packaging bag bundling is performed on a specific number of stacked packaging bags 1, a synchronous signal counting device (also available using the counting device uniformly configured for the packaging bag making machine) is generally provided on the gathering and bundling process of the bag making machine to calculate the number of stacked packaging bags 1. When the specified number of packaging bags 1 is stacked, the bundling process gathers and bundles the packaging bags 1. The specific number of stacked packaging bags 1 has a certain height. The height difference between the belt conveying device 20 and the horizontal part of the stacking rack 31 is equivalent to or slightly higher than the height of the stacked packaging bags 1.

[0046] In this embodiment, the horizontal stacking surface of the stacking rack 31 adopts parallel tooth distribution, and a plurality of racks of teeth are arranged horizontally to form the stacking surface to carry the packaging bags 1 to be gathered. The overturning angle of the stacking rack 31 is preferably 0-90°.

[0047] In the embodiment, the bag shaking device 4 is installed below the belt conveying device 20, which is convenient for shaking and arranging the stacked bags 1 on the stacking frame 31 and saves space; the shaking rod 40 is connected with a driving device, and the driving device drives the shaking rod 40 to shake; the driving device can be a commonly used driving motor; the height of the shaking plate 41 can be equivalent to or slightly higher than the height of the stacked bags 1.

[0048] In the embodiment, the lifting platform 50 of the lifting bag stacking device is a frame structure, wherein the upper surface 500 of the frame structure is provided with a toothed structure, and the upper surface 500 and the lower surface 501 are supported by the support columns 502; based on the structure, in some embodiments, the toothed structure of the upper surface 500 and the support columns 502 are integrated, that is, the support columns 502 are columnar structures, a plurality of support columns 502 are arranged longitudinally and transversely, there is a gap between adjacent two support columns 502, and the upper surface of the support column 502 serves as the upper surface 500 of the lifting platform 50 to carry the bags 1 to be rolled up; in other embodiments, the upper surface 500 and the support columns 502 are independent of each other, and each tooth of the upper surface 500 can be supported by one or more support columns 502, and there is a gap between adjacent two teeth on the upper surface 500; in some other embodiments, the outer circle of the teeth of the upper surface 500 is provided with an outer frame which surrounds three sides to fix the teeth, and one side is left open to allow the rotating bag turning mechanism 6 to enter the lifting platform 50 to remove the bags 1 to be rolled up; in some other embodiments, the support column 502 is a columnar structure, and a plurality of parallel grooves or protrusions are arranged on the upper surface of the columnar structure, the upper surface of the protrusion part of the groove or protrusion is the upper surface 500 of the lifting platform 50, and the rotating bag turning mechanism 6 enters the lifting platform 50 through the recessed part of the groove or protrusion to remove the bags 1 to be rolled up; the above several embodiments can all achieve the transfer of the bags 1 to be rolled up.

[0049] It should be noted that no matter which form the lifting platform 50 adopts, the toothed structure of the upper surface 500 of the lifting platform 50 and the toothed structure of the stacking frame 31 are staggered, when the bags 1 to be rolled up need to be transferred, the lifting platform 50 is located below the stacking frame 31, the teeth of the stacking frame 31 are rotated downward, the bags 1 to be rolled up are placed on the upper surface 500 of the lifting platform 50, and then are rotated out through the gap of the support columns 502 to perform the stacking operation of the next batch of bags, so that the bags 1 to be rolled up are conveniently transferred and are not scattered during the transfer.

[0050] In the embodiment, the lifting platform 50 is driven to lift by a lifting control mechanism, which can be a servo motor combined with a lifting track or a servo motor combined with a lifting pulley, as long as the lifting platform 50 can be freely lifted.

[0051] In the embodiment, the structure of the turnover frame 60 in the rotary bag turning device 6 and the stacking frame 31 is basically the same, at least including a turnover surface 601 and a turnover shaft 600, wherein the turnover surface 601 adopts a parallel tooth structure distribution, a plurality of tooth-shaped frame bodies are arranged into a turnover surface, each turnover frame 60 includes at least two turnover surfaces 601, and the two turnover surfaces 601 are distributed at right angles with the turnover shaft 600 as the axis; the difference from the stacking frame 31 is that the turnover angle of the turnover frame 60 is preferably 0-180°; the tooth structure of the turnover surface 601 is staggered with the tooth structure of the upper surface 500 of the lifting platform 50, and is used to move the stacked packaging bags 1 on the upper surface 500 of the lifting platform 50 out of the lifting platform 50.

[0052] The rotary frame 60 of the rotary bag turning device 6 is connected with a translation device, and the movement of the turnover frame 60 in the horizontal direction is controlled through the translation device; when the packaging bags 1 need to be transferred, one of the turnover surfaces of the turnover frame 60 is horizontal and faces the side of the lifting platform 50; at this time, the translation device drives the turnover frame 60 to move to the side of the lifting platform 50, and the tooth structure on the turnover surface 601 in the horizontal position passes through the gap between the tooth structures of the upper surface 500 of the lifting platform 50; the packaging bags 1 to be collected are moved to the turnover frame 60, the translation device is driven towards the direction of the turnover platform 61, the turnover frame 60 is moved out of the lifting platform 50 and moves to the side of the turnover platform 61; at this time, the turnover frame 60 is rotated through the turnover shaft 600, the packaging bags 1 to be collected are moved to the turnover platform 61, and are clamped by the clamping device 7 on the side of the turnover platform 61.

[0053] The double-out bag arranging machine for the bag making machine further includes a bundling device 8 located in the next working position of the clamping device 7; since the volume of the bundling device 8 is large, the bundling device is generally arranged outside the cover shell 22, and a conveying device is generally arranged on the bundling device 8; when the clamping device 7 places the clamped packaging bags 1 to be collected on the bundling device 8, the conveying device conveys the packaging bags 1 to a suitable position for bundling.

[0054] Based on the above structure, in the embodiment, the process flow of the double-out bag arranging and bundling machine is as follows: after the packaging bags 1 are cut into independent packaging bags 1 after processing, the packaging bags 1 are conveyed to the packaging bag folding and bundling process through the belt conveying device 20. During the conveying process, when the detection device of the bag making machine detects a packaging bag that does not meet the requirements, the packaging bag is removed from the waste bag outlet 23 through the bag blocking device 21. The remaining packaging bags 1 that meet the requirements enter the packaging bag folding and bundling process and are conveyed to the rotary bag stacking device 3 through the belt conveying device 20, and are stacked on the stacking frame 31. At this time, the synchronous signal counting device of the bag making machine calculates the number of conveyed packaging bags. When the specified stacking number is reached, the control system controls the bag arranging device 4 to arrange the packaging bags 1 on the stacking frame 31, and controls the lifting control mechanism to drive the lifting platform 50 to move upward. The rotary bag stacking device 3 rotates to move the packaging bags 1 to be folded to the lifting platform 50. The stacking frame 31 rotates to move out of the lifting platform 50. The lifting control mechanism moves the lifting platform 50 downward to move out of the rotary bag stacking device 3. The rotating bag turning device 6 is controlled by the translation device to move to the lifting platform 50. The packaging bags 1 to be folded on the lifting platform 50 are removed from the lifting bag stacking device and moved to the turning table 61. The clamping device 7 clamps and transfers the packaging bags 1 to the bundling device 8 for bundling. Thus, the folding and bundling process of the packaging bags 1 to be folded is completed.
