Description

Technical Field

[0001] This utility model relates to the field of packaging machines, specifically to a linear cam bag-picking device for a bag-feeding packaging machine. Background Technology

[0002] Existing automated packaging machines typically employ a modular design, including a material supply and metering system, a packaging execution system, and a control system. Their workflow is as follows: the supply system delivers the product to the packaging position in a directional and quantitative manner; the packaging execution system performs bag removal, packaging and sealing in sequence, and finally the finished product is output by the conveyor belt.

[0003] During the bag-retrieving process, packaging machines generally have modular bag-retrieving devices. Existing bag-retrieving devices generally include a storage tank and a bag-retrieving structure. The bag-retrieving structure picks up the packaging bags from above the storage tank by negative pressure adsorption. As the packaging bags are consumed, the stacking height decreases, requiring the bag-retrieving structure to adapt in real time, and the process needs to be paused when replenishing packaging bags. Utility Model Content

[0004] The purpose of this invention is to provide a linear cam bag-picking device for a bag-packing machine, which solves the problem caused by the decrease in storage height of existing bag-picking devices.

[0005] This utility model achieves the above objectives through the following technical solutions: A linear cam bag-picking device for a bag-packing machine includes a first frame, a second frame, a bag-storing mechanism disposed on the first frame, and a bag-picking mechanism disposed on the second frame. The bag-retrieving mechanism includes a linearly sliding slide, a swing arm oscillating on the slide, and an adsorption assembly on the swing arm. The second frame is provided with a guide groove, and the axial portion of the swing arm is eccentrically provided with a guide corresponding to the guide groove. The guide is used to drive the swing arm to oscillate when the slide slides linearly.

[0006] As a preferred embodiment of this utility model, the second frame is provided with a track adapted to the slide, and a telescopic component for driving the slide to slide is also provided. This embodiment guides the slide by setting a track, specifically, the track is set as an I-shaped strip track.

[0007] In a preferred embodiment of this utility model, the guide component is a guide wheel, which is rotatably connected to a cam located at the end of the shaft. By setting a cam and a guide wheel on the shaft, the guide wheel can guide the cam to rotate in the guide groove, thereby driving the shaft to rotate. Setting a guide wheel can reduce friction and improve the guiding effect.

[0008] As a preferred embodiment of this utility model, the adsorption assembly includes a rail that slides along the swing arm, at least one pair of sliders that slide on the rail, and an adsorption part disposed on the slider. The swing arm is perpendicular to the rail. In this embodiment, the adsorption assembly is further configured as a pair of adsorption parts with adjustable spacing, which can be adaptively adjusted according to the width of the packaging bag.

[0009] As a preferred embodiment of this utility model, the slider and the rail have a locking structure. By setting the locking structure, the slider is fixed in position on the rail. The locking structure can be set as a bolt, which is tightened to fix it.

[0010] As a preferred embodiment of the present invention, the bag storage mechanism includes at least one pair of baffles disposed on the first frame, and a plurality of supporting ribs are disposed between the bottom of the baffles for supporting the packaging bag. The width of the packaging bag is limited by the baffles, and the supporting ribs are disposed across the bottom of the baffles for supporting the packaging bag. The gaps between the supporting ribs are used for bag retrieval.

[0011] In a preferred embodiment of this utility model, one of the baffles is slidably connected along the first frame, and the first frame is provided with an adjustment mechanism for adjusting the position of the baffle. In this embodiment, by setting the adjustment mechanism, the spacing between the baffles can be adjusted to adapt to the width of different packaging bags. In this embodiment, one end of the support rib is connected to the fixed baffle, and the other end is slidably connected to the movable baffle.

[0012] As a preferred embodiment of this utility model, the surface of the baffle is provided with a fixing block and an adjusting block for limiting the two ends of the packaging bag, respectively. The baffle is provided with an adjusting groove for the adjusting block to move and a fixing bolt for fixing the adjusting block. This solution is used to adapt to the length of the packaging bag. The adjusting block is adjusted and the fixing bolt is used to press and fix it.

[0013] The beneficial effects of this utility model are as follows: by setting a linear motion slide, and setting a swing arm and a guide component eccentrically set with the axis of the swing arm on the slide, the slide drives the swing arm to rotate during the linear motion, thereby making the adsorption component lift the bag upwards, and then turn to pick up the bag from the bottom of the bag storage mechanism after removal. There is no impact from the change in stacking height, and it is not necessary to stop when replenishing packaging bags. Attached Figure Description

Detailed Implementation

[0015] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0016] Example 1 like Figure 1-5 As shown, a linear cam bag-picking device for a bag-packing machine includes a first frame 1, a second frame 2, a bag-storing mechanism 3 disposed on the first frame 1, and a bag-picking mechanism 4 disposed on the second frame 2. The bag-taking mechanism 4 includes a linearly sliding slide 42, a swing arm 44 oscillating on the slide 42, and an adsorption assembly on the swing arm 44. The second frame 2 is provided with a guide groove 21, and the shaft portion 43 of the swing arm 44 is eccentrically provided with a guide corresponding to the guide groove 21. The guide is used to drive the swing arm 44 to oscillate when the slide 42 slides linearly.

[0017] This solution sets up a linear motion slide 42, and sets a swing arm 44 on the slide 42 and a guide component that is eccentrically set with the shaft 43 of the swing arm 44. This allows the slide 42 to drive the swing arm 44 to rotate during linear motion, thereby causing the adsorption component to pick up the bag upwards. After the bag is removed, it turns to pick up the bag from the bottom of the bag storage mechanism 3. There is no impact from changes in stacking height, and it does not need to stop when replenishing packaging bags. When using, such as Figure 4 As shown, the guide groove 21 has three sections: vertical at both ends and inclined in the middle. The slide 42 moves linearly in the vertical direction. The eccentric guide has no effect when it is in the vertical section of the guide groove 21 and will not drive the swing arm 44 to rotate, so that the swing arm 44 is in a lifting motion. When the guide enters the inclined section, it drives the shaft 43 to rotate, which in turn causes the swing arm 44 to rotate, changing the direction of the adsorption component, which facilitates bag picking and subsequent packaging.

[0018] Preferably, the second frame 2 is provided with a track 41 adapted to the slide 42, and also with a telescopic member 48 for driving the slide 42 to slide. In this solution, the track 41 is set to guide the slide 42. Specifically, the track 41 is set as an I-shaped strip rail.

[0019] Preferably, the guide is a guide wheel 410, which is rotatably connected to a cam 49 located at the end of the shaft 43. By setting the cam 49 and the guide wheel 410 on the shaft 43, the guide wheel 410 can guide the cam 49 to rotate in the guide groove 21, thereby driving the shaft 43 to rotate. Setting the guide wheel 410 can reduce friction and improve the guiding effect.

[0020] The adsorption assembly includes a rail 45 slidably mounted along a swing arm 44, at least one pair of sliders 46 slidably mounted on the rail 45, and adsorption parts 47 mounted on the sliders 46. The swing arm 44 is perpendicular to the rail 45. This design further configures the adsorption assembly as a pair of adsorption parts 47 with adjustable spacing, allowing for adaptive adjustment based on the width of the packaging bag. A locking structure exists between the sliders 46 and the rail 45, fixing the sliders in place on the rail 45. The locking structure can be a bolt, tightened for secure fixation. The adsorption parts 47 are connected to an external negative pressure source via a pipe.

[0021] The bag storage mechanism 3 includes at least one pair of baffles 31 disposed on the first frame 1. Several support ribs 37 are disposed between the bottom of the baffles 31 to support the packaging bag. The width of the packaging bag is limited by the baffles 31. Support ribs 37 are disposed across the bottom of the baffles 31 to support the packaging bag. The gaps between the support ribs 37 are used for bag retrieval.

[0022] Preferably, one of the baffles 31 is slidably connected along the first frame 1, and the first frame 1 is provided with an adjustment mechanism 32 for adjusting the position of the baffle 31. By setting the adjustment mechanism 32, the spacing of the baffles 31 can be adjusted to adapt to the width of different packaging bags. Specifically, the adjustment mechanism 32 can be a threaded rod, and the sliding baffle 31 is connected to the threaded rod. The baffle 31 is adjusted by rotation. In this scheme, one end of the support rib 37 is connected to the fixed baffle 31, and the other end is slidably connected to the movable baffle 31.

[0023] The surface of the baffle 31 is provided with a fixed block 33 and an adjusting block 35 for limiting the two ends of the packaging bag. The baffle 31 is provided with an adjusting groove 34 for the adjusting block 35 to move and a fixing bolt 36 for fixing the adjusting block 35. This solution is used to adapt to the length of the packaging bag. The adjusting block 35 is moved to a certain position and then pressed and fixed by the fixing bolt 36.

[0024] Please see Figure 4-5The dotted line represents a positional diagram of the swing arm 44 during its movement. When the guide wheel 410 is at the highest point of the guide groove 21, the suction part 47 moves towards the packaging bag, and then the slide 42 descends, pulling the packaging bag downwards. When the guide wheel 410 enters the inclined section of the guide groove 21, the cam 49 drives the shaft 43 to rotate, causing the swing arm 44 to swing. The suction part 47 drives the packaging bag to change direction, as shown by the dotted line, to facilitate further operation of the packaging bag by the subsequent packaging mechanism. When resetting, the telescopic part 48 pushes the slide 42 back along the original path.

[0025] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
