Description

Technical Field

[0001] This invention relates to the field of feed packaging technology, and in particular to an automatic palletizing device for feed packaging bags. Background Technology

[0002] In the field of feed production and packaging technology, after feed is processed, it is packaged into bags and sealed. Then, palletizing equipment is used to automatically stack these bags into a stack. In existing technologies, palletizing robot grippers typically use a symmetrical rotating mechanism on both sides to open and close. When the grippers are open, the grippers are tilted at a large angle, causing the feed on both sides to tend to converge towards the center as the bag falls. The bag falls with a downward convex shape in the middle, and upon landing, it may come into contact with the bag below, easily causing misalignment. This results in an uneven stack shape and affects stability. Furthermore, because the grippers require space to rotate and open, the bag needs to be placed at a certain height from the lower layer. The vibration generated when the bag is placed can easily cause the edge of the stack to shift or even fall off. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies where the two sides of the gripper are tilted at a large angle, causing feed on both sides of the feed bag to tend to converge towards the middle when it falls, and causing the feed bag to come into contact with the feed bag below it after falling, resulting in easy displacement, and requiring the feed bag to be placed at a certain height from the lower layer, resulting in an uneven stack shape and affecting stability, this invention provides an automatic feed bag stacking device.

[0005] Optionally, the translational support assembly includes two support units distributed perpendicularly to each other. Each support unit includes a first mounting frame fixedly connected to the rotating part of the first electric shaft, a plurality of first electric straight-moving mechanisms connected to the first mounting frame, a fixed frame connected to all the first electric straight-moving mechanisms, a mounting plate fixedly connected to the fixed frame, an adjustable support module connected to the mounting plate, and a dust removal module connected to the mounting plate; wherein the dust removal module is connected to the adjustable support module.

[0006] Optionally, the adjustable support module includes a second electric straight-moving mechanism connected to the mounting plate, a plurality of support mechanisms connected to the second electric straight-moving mechanism, and a tilting mechanism connected to the mounting plate; wherein the tilting mechanism is connected to all the support mechanisms, and the support mechanism includes a connecting frame fixed to the mounting plate, a support plate movably connected to the connecting frame via a connecting block and a rotating shaft, and a plurality of guide rollers rotatably connected to the support plate.

[0007] Optionally, the highest and lowest points of the outer annular surface of the guide roller are exposed on the upper and lower surfaces of the support plate, respectively.

[0008] Optionally, the tilting mechanism includes two fixed plates respectively fixed to both ends of the mounting plate, two second electric shafts respectively connected to the two fixed plates, two connecting plates respectively fixed to the rotating parts of the two second electric shafts, a sliding rod fixed to both connecting plates via a connecting rod, and two rotating rings respectively rotatably connected to both ends of the sliding rod; wherein, each side of the mounting plate has an arc-shaped limiting groove for limiting the sliding rod and the rotating rings, and each side of the mounting plate has an arc-shaped through groove matching the two arc-shaped limiting grooves; the axes of the two second electric shafts coincide with the axis of the rotating shaft at the movable connection between the support plate and the connecting frame.

[0009] Optionally, the limiting assembly includes two limiting units respectively connected to the two supporting units. Each limiting unit includes a plurality of first electric push rods fixed to the mounting plate via a connecting block and a limiting plate fixed together with the telescopic ends of the plurality of first electric push rods.

[0010] Optionally, the rolling assembly includes two rolling units respectively connected to the two supporting units. Each rolling unit includes a plurality of second electric push rods fixedly connected to the fixed frame, a second mounting frame fixedly connected to the telescopic ends of the plurality of second electric push rods, two mutually symmetrical third electric push rods fixedly connected to the lower side of the second mounting frame, two elastic telescopic plates fixedly connected to the telescopic ends of the two third electric push rods respectively, and a telescopic member rotatably connected to the telescopic ends of the two elastic telescopic plates via a rotating shaft.

[0011] Optionally, the telescopic member is configured as a cylindrical bidirectional telescopic rod.

[0012] Optionally, the dust removal module includes two dust removal mechanisms respectively connected to the two support units. Each dust removal mechanism includes a vacuum cleaner fixed to the mounting plate and a plurality of vacuuming components connected to the vacuum cleaner; wherein each vacuuming component is connected to a corresponding support plate.

[0013] Optionally, the dust collection component includes an air duct frame fixedly connected to the support plate, a plurality of dust collection boxes communicating with the air duct frame, and a telescopic tube communicating with the air duct frame; wherein, the mounting plate has a through slot for the telescopic tube to move; each dust collection box is directly opposite to the outer ring surface of a corresponding guide roller, each dust collection box is provided with bristles that contact the outer ring surface of the corresponding guide roller, and each dust collection box has a plurality of dust collection holes on the side facing the outer ring surface of the corresponding guide roller.

[0014] The beneficial effects of this invention are: 1. The feed packaging bags are placed by sliding and pulling out two supporting units, so that the bottom of the feed packaging bags are close to the lower layer when they are placed. This avoids dust flying when the feed packaging bags are dropped from a certain height, and also avoids the feed packaging bags at the edge of the stack vibrating and shifting due to the dropping. It also avoids the feed packaging bags falling with the middle convex.

[0015] 2. When the support plate is removed, the bidirectional telescopic rod moves synchronously and rolls over the feed packaging bag to flatten the feed inside the bag, ensuring that the feed is evenly distributed after the upper feed packaging bags are placed, thus guaranteeing the stability of the upper feed packaging bags.

[0016] 3. As the support plate is removed, the guide rollers adhere to the surfaces of the upper and lower feed packaging bags, causing powder to stick to them. The powder adhered to the guide rollers rotates and passes through the bristles on the dust collection box. The bristles brush away the powder adhering to the surface of the guide rollers, and the suction holes on the dust collection box generate suction to collect the brushed-off powder. This maintains the adhesion effect during the rolling of the guide rollers, thereby achieving the effect of removing powder from the surface of the upper and lower feed packaging bags and avoiding the impact of a large amount of powder adhering to the surface of the feed packaging bags on the stability of the stack.

Detailed Implementation

[0019] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0020] Example according to Figures 1-9 As shown, this embodiment provides an automatic palletizing device for feed packaging bags, including a robotic arm 1, a limiting component, and a rolling component: wherein, the robotic arm 1 has a first electric shaft 2 installed at its end, and the rotating part of the first electric shaft 2 is connected to a translational support component; the limiting component is disposed on the support component and cooperates with the translational support component to limit the packaging bag; the rolling component is connected to the translational support component and cooperates with the translational support component to roll the packaging bag.

[0021] The translational support assembly includes two mutually perpendicular support units. Each support unit includes a first mounting frame 3 fixedly connected to the rotating part of the first electric shaft 2, a plurality of first electric straight-moving mechanisms 4 connected to the first mounting frame 3, a fixed frame 5 connected to all the first electric straight-moving mechanisms 4, a mounting plate 6 fixedly connected to the fixed frame 5, an adjustable support module connected to the mounting plate 6, and a dust removal module connected to the mounting plate 6. When the feed packaging bags 001 need to be misaligned during the stacking process, the first electric shaft 2 drives the first mounting frame 3 and its connected components to rotate, thereby driving the feed packaging bags 001 to rotate and adjust their orientation.

[0022] The dust removal module is connected to the adjustable support module. In this embodiment, the first electric straight-line mechanism 4 is configured as an electric slide rail and an electric slider. By controlling the electric slider to move on the electric slide rail, the corresponding parts can be moved. In other embodiments, linear drive can also be achieved by means of linear motor, cylinder and gear rack combination, etc.

[0023] The adjustable support module includes a second electric straight-line mechanism 14 connected to the mounting plate 6, a plurality of support mechanisms connected to the second electric straight-line mechanism 14, and a tilting mechanism connected to the mounting plate 6. In this embodiment, the second electric straight-line mechanism 14 is configured as an electric slide rail and an electric slider. By controlling the electric slider to move on the electric slide rail, the connecting frame 15 is moved. In other embodiments, linear drive can also be achieved by means of linear motor, cylinder and gear rack combination, etc. The tilting mechanism is connected to all the supporting mechanisms. The supporting mechanism includes a connecting frame 15 fixed to the mounting plate 6, a support plate 16 movably connected to the connecting frame 15 via a connecting block and a rotating shaft, and a plurality of guide rollers 21 rotatably connected to the support plate 16.

[0024] The highest and lowest points of the outer ring surface of the guide roller 21 are exposed on the upper and lower surfaces of the support plate 16, respectively. This allows the outer ring surface of the guide roller 21 to simultaneously contact the surfaces of the upper and lower layers of feed packaging bags 001, and to adhere powder to the surface of the feed packaging bags 001 by rolling.

[0025] The tilting mechanism includes two fixed plates 18 respectively fixed to both ends of the mounting plate 6, two second electric shafts 19 respectively connected to the two fixed plates 18, two connecting plates 20 respectively fixed to the rotating parts of the two second electric shafts 19, a sliding rod 17 fixed to both connecting plates 20 through a connecting rod, and two rotating rings 1701 respectively rotatably connected to both ends of the sliding rod 17. The mounting plate 6 has an arc-shaped limiting groove 602 on each side for limiting the sliding rod 17 and the rotating ring 1701, and an arc-shaped through groove 603 on each side that matches the two arc-shaped limiting grooves 602. The rotating ring 1701 is limited by the arc-shaped limiting grooves 602. When the sliding rod 17 is driven to rotate by the second electric shaft 19 through the connecting plate 20, the rotating ring 1701 rolls in the arc-shaped limiting groove 602 and rotates on the sliding rod 17 at the same time, which reduces the wear between the rotating ring 1701 and the mounting plate 6. The second electric shaft 19 has a locking function so that the sliding rod 17 is fixed in a preset position. The axes of the two second electric shafts 19 coincide with the axis of the rotating shaft at the movable connection between the support plate 16 and the connecting frame 15.

[0026] The limiting assembly includes two limiting units respectively connected to the two supporting units. Each limiting unit includes a plurality of first electric push rods 7 fixedly connected to the mounting plate 6 via a connecting block and a limiting plate 8 fixedly connected to the telescopic ends of the plurality of first electric push rods 7.

[0027] The rolling assembly includes two rolling units respectively connected to the two supporting units. Each rolling unit includes a plurality of second electric push rods 9 fixedly connected to the fixed frame 5, a second mounting frame 10 fixedly connected to the telescopic ends of the plurality of second electric push rods 9, two mutually symmetrical third electric push rods 13 fixedly connected to the lower side of the second mounting frame 10, two elastic telescopic plates 11 fixedly connected to the telescopic ends of the two third electric push rods 13 respectively, and a telescopic member rotatably connected to the telescopic ends of the two elastic telescopic plates 11 via a rotating shaft.

[0028] The telescopic component is configured as a cylindrical bidirectional telescopic rod 12. In other embodiments, the telescopic component can also be configured as a pentagonal, hexagonal, or other bidirectional telescopic structure that can roll by friction.

[0029] The dust removal module includes two dust removal mechanisms connected to the two supporting units respectively. Each dust removal mechanism includes a vacuum cleaner 23 fixed to the mounting plate 6 and several dust removal components connected to the vacuum cleaner 23. The dust is collected by the dust removal components through the suction generated by the vacuum cleaner 23 and then uniformly collected in the vacuum cleaner 23. After the work is completed, the collected dust can be uniformly processed. Each of the vacuuming components is connected to a corresponding support plate 16.

[0030] The dust collection component includes an air duct frame 1601 fixedly connected to the support plate 16, a plurality of dust collection boxes 22 communicating with the air duct frame 1601, and a telescopic tube 1602 communicating with the air duct frame 1601. The mounting plate 6 has a through slot 601 for the movement of the telescopic tube 1602; by setting the telescopic tube 1602 and the through slot 601, the telescopic tube 1602 is prevented from being damaged by rigid tension when the support plate 16 rotates. Each of the dust collection boxes 22 is directly opposite to the outer ring surface of a corresponding guide roller 21. Each dust collection box 22 is provided with bristles that contact the outer ring surface of the corresponding guide roller 21. Each dust collection box 22 has a number of dust collection holes on the side facing the outer ring surface of the corresponding guide roller 21.

[0031] During installation, the robotic arm 1 is fixedly installed at the end of the existing feed packaging bag 001 conveying equipment. During production, after the feed is filled and sealed, the conveying equipment transports the sealed feed packaging bag 001 to the designated position, so that the feed packaging bag 001 is in a flat position waiting to be grasped. The robotic arm 1 drives the translational support assembly to move, so that the upper surface of the support plate 16 is flush with the bottom surface of the feed packaging bag 001. At the same time, the two support units drive the corresponding fixing frame 5 and its connected parts to move through their respective first electric straight-moving mechanism 4, so that the two fixing frames 5 separate from each other. Figure 1 Based on this, the right-hand fixed frame 5 and its connected parts move to the right, and the front fixed frame 5 and its connected parts move to the front. Then, the robotic arm 1 moves the translational support assembly to a preset position, whereby the translational support assembly is ready to support the feed packaging bag 001. Next, the two fixed frames 5 and their connected parts are controlled to move and reset. The movement distance of the two fixed frames 5 is controlled according to the specifications of the feed packaging bag 001. The first electric push rod 7 is extended to push the limiting plate 8 to move, so that the limiting plate 8 limits the side of the feed packaging bag 001 after the fixed frame 5 has moved. Then, several support plates 16 support the bottom of the feed packaging bag 001, and the two limiting plates 8 limit the side of the feed packaging bag 001. The state is as follows. Figure 1 As shown, to accommodate feed packaging bags 001 of different specifications, and to prevent the feed packaging bags 001 filled with powdered feed from sinking or even falling when supported by several spaced-apart support plates 16, the connecting frame 15 and the support plates 16 are moved by the second electric linear mechanism 14 before support. This allows adjustment of the spacing between the support plates 16, preventing the packaging bags filled with powdered feed from sinking due to excessive spacing between the support plates 16, which would lead to uneven feed distribution and affect stacking quality. The same spacing adjustment operation can also be used to support smaller feed packaging bags 001. By reducing the spacing between the support plates 16, more support plates 16 can be involved in supporting the smaller feed packaging bags, increasing the support for the smaller bags. The stability of the 001 support gives the translational support assembly good adaptability. After the translational support assembly supports the feed packaging bag 001, the robotic arm 1 moves the feed packaging bag 001 to a designated position on the pallet, so that the guide roller 21 on the support plate 16 contacts the upper side of the pallet. Then, the two fixed frames 5 are controlled to separate from each other, and the first electric push rod 7 on them extends synchronously, so that the two limiting plates 8 always maintain the limiting state of the feed packaging bag 001, preventing the feed packaging bag 001 from shifting or misaligning due to friction when the support plate 16 is pulled away from the bottom surface of the feed packaging bag 001. When placing the second layer and subsequent higher layers of feed packaging bags 001, before controlling the two fixed frames 5 to separate from each other and pull the support plate 16 away from the bottom surface of the feed packaging bag 001, Figure 1Taking the right-hand support unit as an example, by controlling the rotation of the second electric shaft 19, the connecting plate 20 is driven by the connecting rod to rotate the slide rod 17 counterclockwise by a preset angle, causing the rotating ring 1701 to roll in the arc-shaped limiting groove 602. This, in turn, causes the slide rod 17 to drive the support plate 16 to rotate about the axis of connection with the connecting frame 15, thus tilting the support plate 16. This reduces the contact pressure between the support plate 16 (except at one end) and the surface of the lower feed packaging bags 001, preventing the feed packaging bags 001 from shifting or misaligning due to friction when the support plate 16 is removed, thus ensuring the stability of the stack. By having the guide roller 21 contact the lower feed packaging bag 001, some of the sliding friction is converted into rolling friction, further reducing the friction force. After the support plate 16 is completely removed, the feed packaging bag 001 is placed in the preset position. The feed packaging bag 001 is placed by the two supporting units being moved and removed, so that the bottom surface of the feed packaging bag 001 is close to the lower layer for placement. This avoids dust flying when the feed packaging bag 001 is dropped from a certain height, and also avoids the situation where the feed packaging bag 001 at the edge of the stack vibrates and shifts due to placement. It also avoids the situation where the feed packaging bag 001 falls with a convex shape in the middle.

[0032] For feed bags 001 with high feed flowability, to ensure the feed is evenly distributed after the feed bags 001 are placed to guarantee the stability of the upper feed bags 001, before the support plate 16 is removed, the second electric push rod 9 is extended according to the specifications of the feed bags 001. This causes the second mounting bracket 10 and its connected parts to move downwards a preset distance, bringing the bidirectional telescopic rod 12 into contact with and being compressed by the feed bags 001. This compresses the elastic telescopic plate 11, thereby causing the bidirectional telescopic rod 12 to exert pressure on the feed bags. A preset pressure is applied to bag 001, so that when the support plate 16 is pulled away, the bidirectional telescopic rod 12 moves synchronously to roll over the feed packaging bag 001, flattening the feed inside the feed packaging bag 001. Before rolling, the elastic telescopic plate 11 is driven by the retraction of the third electric push rod 13 to retract the bidirectional telescopic rod 12, so that the bidirectional telescopic rod 12 can adapt to feed packaging bags 001 of different specifications. This ensures that the bidirectional telescopic rod 12 has an appropriate length while avoiding the bidirectional telescopic rod 12 being too long and obstructed by the feed packaging bags 001 placed next to it.

[0033] When there is loose powder on the surface of feed packaging bag 001, the large amount of powder adhering to the surface of feed packaging bag 001 will produce a solid lubricant effect, which will reduce the friction between the upper and lower layers and thus affect the stability of the stack. When the support plate 16 is removed, the guide roller 21 rolls against the surface of the upper and lower feed packaging bags 001 to adhere the powder. At the same time, the vacuum cleaner 23 is started. The suction hole on the vacuum box 22 generates suction through the telescopic tube 1602 and the air pipe frame 1601. At the same time, the powder adhering to the guide roller 21 rotates and passes through the bristles on the vacuum box 22. The bristles brush off the powder adhering to the surface of the guide roller 21. The suction hole on the vacuum box 22 generates suction to collect the brushed-off powder, so that the guide roller 21 maintains the adhesion effect during the rolling process. This achieves the effect of removing part of the powder on the surface of the upper and lower feed packaging bags 001 and avoids the impact of a large amount of powder adhering to the surface of the feed packaging bags 001 on the stability of the stack.
