Description

Technical Field

[0001] The utility model relates to an online bag stacking machine. Background Art

[0002] Grain, feed, salt, seeds, milk powder and other powders and granules need to be stacked after vacuum bagging. The current market mostly uses cartons for vacuum packaging. In order to save packing costs, the market has gradually adopted the packaging method of heat shrink film, which can basically meet the transportation and storage needs like carton packing, and greatly reduce costs; currently stacking usually relies on manual stacking. With the market demand, relying solely on manual stacking has the following disadvantages: 1. Manual stacking is inefficient and cannot meet the needs of the existing market; 2. Manual stacking is uneven, which makes subsequent packaging inconvenient. Therefore, the packaging industry has an increasing demand for high-speed stacking machines. Before stacking, the material bags need to be transferred and pushed, etc. The current pushing often has problems such as inadequate pushing or excessive pushing, which causes the position of the material bags to shift, affecting the subsequent stacking effect, and needs to be improved urgently.

Specific Embodiments

[0023] To make the above features and advantages of the present utility model more obvious and understandable, specific embodiments are hereinafter given and described in detail in conjunction with the accompanying drawings as follows.

[0024] As Figures 1-6 shown, an in-line packing machine for material packets includes a main frame 1 and a packing conveying mechanism 23 arranged in the main frame. The packing conveying mechanism is composed of a synchronous lifting component and a conveying mechanism. The synchronous lifting component includes a driving shaft 24. Two groups of synchronous pulleys 25 are arranged at intervals up and down at the top end of the driving shaft, and the driving shaft drives the synchronous pulleys to rotate. The two groups of synchronous pulleys are respectively synchronously linked with two lifting groups 27 through synchronous belts 26. The two synchronous belts are vertically offset and horizontally extended to be connected with two lead screw synchronous pulleys for linkage. Each lifting group is composed of two ball screws 28, a lifting table 29, a lead screw synchronous pulley 30, and a lead screw synchronous belt 31. The two ball screws are arranged vertically. One of the ball screws is provided with lead screw synchronous pulleys at both the upper and lower ends. The lead screw synchronous pulley at the top end is connected with the synchronous belt, and the lead screw synchronous pulley at the lower end is linked with the lead screw synchronous pulley arranged at the lower end of the other ball screw through the lead screw synchronous belt. The two ball screws are connected with the lifting table through lead screw nuts, and the lifting tables are horizontally extended and fixedly connected together to support the conveying mechanism. The two ball screws are respectively arranged on both longitudinal sides of the conveying mechanism.

[0025] In the embodiment of the present utility model, the two lifting groups are horizontally arranged at intervals below the conveying mechanism. Fixed plates 32 are arranged in parallel above and below the lifting table. Guide holes 33 are vertically formed on both horizontal sides of the lifting table. Vertically extending guide posts 34 are slidably fitted in the guide holes. The upper and lower ends of the guide posts are respectively fixedly connected to the fixed plates, and the fixed plates are fixedly connected to the main frame.

[0026] In the embodiment of the present utility model, the lower end of the driving shaft is connected with a speed reducer 36 and a servo motor 37 through a coupling 35; limit switches 38 for restricting excessive lifting are arranged on the lifting paths of the lifting tables, and a proximity switch 39 is arranged on the fixed plate located below.

The conveyor belt is driven by a motor, which is a common setting and will not be elaborated here.

[0028] In an embodiment of the present utility model, a pushing mechanism for pushing the material packages into the stacked package conveying mechanism is further disposed in the frame above the stacked package conveying mechanism. The pushing mechanism includes a pushing conveyor belt 2, and a pushing frame 3 is disposed above the pushing conveyor belt. A lifting cylinder 4 is fixedly connected to the pushing frame. A pushing plate 5 is fixedly provided at the bottom of the telescopic end of the lifting cylinder. The pushing frame is driven to reciprocate and slide by a longitudinal pushing cylinder 6. At the end of the pushing of the pushing plate, a drawing mechanism 7 for receiving or drawing the package is provided. The drawing mechanism includes a horizontal support plate 8. Both sides of the support plate are slidably connected to the main frame through connecting seats 9. The support plate is driven by a drawing cylinder 10 arranged in parallel with the pushing cylinder. Along the end of the pushing of the pushing cylinder, an overshoot baffle 11 for blocking the over-pushing of the material package or blocking the material package from being linked by the support plate during drawing is provided on the main frame of the pushing cylinder.

[0029] In an embodiment of the present utility model, a pushing component is composed of a pushing frame, a lifting cylinder, a pushing plate, a pushing cylinder, and a pushing slide rail, and an adjusting component is composed of a lead screw, an overshoot baffle, a transverse connecting plate, an adjusting slide rail, a bearing seat, and a crank.

[0030] In an embodiment of the present utility model, a package blocking plate 12 is arranged along the transverse conveying direction of the pushing conveyor belt, and the top of the package blocking plate is driven to vertically lift and lower by a package blocking cylinder 13.

[0031] In an embodiment of the present utility model, two groups of the pushing conveyor belts are provided and are horizontally butted. Lifting cylinders are fixedly provided at the near ends of the transverse two sides of the corresponding pushing frame to respectively push the material packages on the two pushing conveyor belts. The pushing cylinder extends longitudinally, and its telescopic end is fixedly connected to the middle of the pushing frame. Both transverse ends of the pushing frame are slidably connected to the pushing slide rails 14 through sliders, and the pushing slide rails are fixedly connected to the main frame.

[0032] In an embodiment of the present utility model, two groups of the baffle plates and the package blocking cylinders are correspondingly arranged, and are respectively arranged above the input ends of the two pushing conveyor belts to prevent the subsequent material packages from being input together.

[0033] In an embodiment of the present utility model, the overshoot baffles both extend transversely and two groups are symmetrically arranged. The two overshoot baffles are fixedly connected into one body through a transverse connecting plate 15. The middle of the transverse connecting plate is penetrated by a longitudinal lead screw 16 and is driven to longitudinally slide by it. Both ends of the transverse connecting plate are slidably connected to the longitudinal adjusting slide rails 17 through sliders, and the adjusting slide rails are fixedly connected to the main frame.

[0034] In an embodiment of the present utility model, two groups of the support plates are symmetrically arranged. The two groups of support plates are fixedly connected through a linkage plate 18. The telescopic end of the drawing cylinder is hinged to the linkage plate. The tops of the connecting seats are slidably connected to the longitudinal slide rails 19 fixedly connected to the main frame through sliders.

[0036] In the embodiment of the present utility model, an electric control box 20 which is electrically connected to both the bag stacking and conveying mechanism and the bag pushing mechanism is also fixedly provided on the frame.

[0037] In the embodiment of the present utility model, after the specification of the material bag is selected, the position of the overshoot baffle needs to be adjusted by manually shaking the crank first. When the material bags are respectively conveyed onto the two bag pushing conveyor belts, the bag blocking cylinder descends, and the bag pushing conveyor belt stops conveying. Blocked by the bag blocking plate, then the lifting cylinder descends, and the bag pushing plate abuts against the edge of the material bag. Then the bag pushing cylinder contracts to drive the bag pushing plate to longitudinally push the material bag onto the support plate, and the overshoot baffle blocks to prevent excessive longitudinal pushing and dropping. Finally, the bag extracting cylinder contracts and drives the support plate to longitudinally slide, so that the material bag does not move with the support plate under the blocking action of the overshoot baffle, and the material bag freely falls onto the bag stacking conveyor belt for stacking after the support plate moves. At this time, the conveying mechanism is lifted to the highest position by the synchronous lifting assembly, and with each stacking, it descends by the height of one material bag thickness driven by the ball screw to ensure the stability of each conveying and stacking. When the lifting table triggers the travel switch at the bottom, the servo motor stops running, and the proximity switch also monitors that the lifting table reaches the initial position. The conveying mechanism starts to drive the stacked material bags to the next process, and then the synchronous lifting assembly drives the conveying mechanism to rise to the receiving position again for the next round of repeated actions.

[0038] The present utility model is not limited to the above best embodiment, and anyone can obtain other various forms of on-line bag stacking machines for material bags under the inspiration of the present utility model. All equal changes and modifications made according to the scope of the patent application of the present utility model shall fall within the scope covered by the present utility model.
