Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent stacking of angle steels, and particularly relates to an intelligent adaptive unstacking suction cup for stacking angle steels. Background Art

[0002] At present, when angle steels 1 are stored and stacked, the angle steel pallets are generally interlocked in a positive and negative manner and stacked in sequence. Manual palletizing is mostly used. Limited by the limited storage space of production enterprises, enterprises often cannot stack them separately according to different models. Workers can only stack them centrally according to the temporary situation of the incoming or outgoing of angle steels 1. It is impossible to ensure that the quantity and model of each layer are the same. The long angle steels 1 themselves will also cause misalignment of the angle steel stack due to the accumulation of a small amount of deformation or dimensional tolerance. During the processes of moving, hoisting, and transporting the angle steels 1, the stack shape will further change. When the angle steels 1 are needed, workers often need to manually unstack them. Sometimes they unstack them layer by layer, and sometimes they also unstack them by single-strand cable.

[0003] Due to the high noise and heavy dust at the production site of angle steels 1, workers repeat heavy, boring, and single mechanical palletizing actions for a long time, which is extremely easy to cause fatigue and lead to safety accidents. Only relying on manual palletizing has low efficiency and it is difficult to keep up with the production rhythm. Some domestic manufacturers have introduced some large-scale angle steel mechanical palletizing production lines. The inventor believes that such large angle steel mechanical palletizing production lines have poor flexibility and are suitable for neatly stacking angle steels 1 of specific specifications in large quantities layer by layer and then unstacking them layer by layer when needed. In the face of Figure 1 as shown in the figure, when there are misalignments, shortages, or abnormal stacks 11 with different models of angle steels 1, resulting in uneven heights on the surface of the angle steel stack, they cannot be effectively dealt with. Therefore, it is necessary to design an intelligent adaptive unstacking suction cup for stacking angle steels.

[0004] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute the prior art. Summary of the Invention

[0005] The inventor found through research that affected by the limited storage space of enterprises, the stacked angle steels cannot be guaranteed to be stacked separately according to the differences in angle steel models. When the model specifications of the stacked angle steels have a large gap and the interlayer stacking is not neat, resulting in uneven heights on the surface of the angle steel stack, only manual unstacking can be relied on. Workers are tired and the efficiency is low, which cannot meet the requirements of production efficiency.

[0006] In view of at least one of the above technical problems, the present disclosure provides an intelligent adaptive unstacking suction cup for stacking angle steels, and the specific technical solutions are as follows:

[0007] An intelligent adaptive destacking suction cup for stacking angle steels comprises a suction cup frame, a left horizontal frame and a right horizontal frame are relatively arranged on both sides of the suction cup frame, the left horizontal frame and the right horizontal frame are each slidably matched with a plurality of floating seats, the floating seat of the left horizontal frame and the floating seat of the right horizontal frame are used in pairs, a shock absorber is vertically fixed to the floating seat, a vertical limiting mechanism is arranged at the lower part of the shock absorber, a joint bearing is arranged at the lower end of the shock absorber, and the joint bearings of each group of paired floating seats are jointly equipped with a floating frame, a plurality of electromagnetic suction cups are staggered on the left and right sides of the lower end of the floating frame, positioning guide wheels are relatively vertically arranged on both sides of the floating frame, and clamping noses are relatively arranged at both ends of the floating frame, and the clamping noses press against the vertical limiting mechanism from below.

[0009] In some embodiments of the present disclosure, the floating seat is provided with two axis-penetrating channels, and the axis-penetrating channels are used with the transverse axis.

[0010] In some embodiments of the present disclosure, the shaft-penetrating channel is a through hole or a U-shaped groove.

[0011] In some embodiments of the present disclosure, the shock absorber is a spring shock absorber, and the vertical limiting mechanism is arranged on the lower side of the spring of the spring shock absorber.

[0012] In some embodiments of the present disclosure, the vertical limiting mechanism is a pressure plate or an adjustable nut.

[0013] In some embodiments of the present disclosure, the angle between the action directions of the two electromagnetic suction cups staggered left and right is 90 degrees.

[0014] In some embodiments of the present disclosure, the positioning guide wheel includes a connecting rod, which is vertically slidably connected to a floating frame, a wheel frame is provided at the lower end of the connecting rod, a roller is provided in the wheel frame, a support spring is provided between the wheel frame and the floating frame, and the lower end of the electromagnetic suction cup does not protrude beyond the lower end of the roller.

[0015] In some embodiments of the present disclosure, the roller is a ball bearing.

[0019] 3. Through the use of positioning guide wheels and floating frames, the positioning guide wheels can provide alignment guidance for the floating frame, so that the left and right staggered electromagnetic suction cups can contact the middle of the outer surface of the angle steel, ensuring the contact area between the electromagnetic suction cups and the angle steel, thereby ensuring the adsorption quality, making the angle steel destacking operation safer and more reliable.

[0029] As shown in the attached figure Figures 1 to 6 As shown, an intelligent adaptive destacking suction cup for stacking angle steels is designed, including a suction cup frame 2, a left cross frame 21 and a right cross frame 22 are relatively arranged on both sides of the suction cup frame 2, and the left cross frame 21 and the right cross frame 22 are respectively slidably matched with a plurality of floating seats 3, the floating seat 3 of the left cross frame 21 and the floating seat 3 of the right cross frame 22 are used in pairs, and a shock absorber 4 is vertically fixed to the floating seat 3, and a vertical limiting mechanism 41 is arranged at the lower part of the shock absorber 4, and a joint bearing 42 is arranged at the lower end of the shock absorber 4, and a floating frame 5 is commonly provided with the joint bearings 42 of each group of paired floating seats 3, and a floating frame 5 is commonly provided with a plurality of electromagnetic suction cups 51 staggered on the left and right sides of the lower end of the floating frame 5, and positioning guide wheels 52 are relatively vertically arranged on both sides of the floating frame 5, and clamping noses 53 are relatively arranged at both ends of the floating frame 5, and the clamping noses 53 are relatively pressed against the vertical limiting mechanism 41 from below, and the floating frame 5 and the electromagnetic suction cup 51 can float up and down through the arrangement of the floating seat 3 and the floating frame 5.

[0030] In the above implementation, three embodiments are listed to implement the above technical solution:

[0031] Example 1

[0032] like Figures 1 to 6As shown, the present embodiment discloses an intelligent adaptive destacking suction cup for stacking angle steels, including a suction cup frame 2, a left cross frame 21 and a right cross frame 22 are arranged on opposite sides of the suction cup frame 2, the left cross frame 21 and the right cross frame 22 are each slidably matched with a plurality of floating seats 3, the floating seat 3 of the left cross frame 21 and the floating seat 3 of the right cross frame 22 are used in pairs, a shock absorber 4 is vertically fixed to the floating seat 3, a vertical limiting mechanism 41 is arranged at the lower part of the shock absorber 4, a joint bearing 42 is arranged at the lower end of the shock absorber 4, and a floating frame 5 is jointly provided with the joint bearings 42 of each group of paired floating seats 3, and a floating frame 5 is provided with a plurality of electromagnetic suction cups 51 staggered on the left and right sides of the lower end of the floating frame 5, positioning guide wheels 52 are arranged vertically on both sides of the floating frame 5, and clamping noses 53 are arranged at opposite ends of the floating frame 5, and the clamping noses 53 press against the vertical limiting mechanism 41 from below, and through the arrangement of the floating seat 3 and the floating frame 5, the floating frame 5 and the electromagnetic suction cup 51 are arranged in a vertical direction. It can float up and down, and can ensure that when the stacking surface of the angle steel 1 is uneven, the adsorption surface of the electromagnetic suction cup 51 can contact the angle steel 1 that needs to be destackered, so as to realize destacking on demand. The electromagnetic suction cups 51 on different surfaces of each floating frame 5 can be controlled separately to realize destacking on demand; through the matching of the joint bearing 42 and the floating frame 5, the floating frame 5 and the electromagnetic suction cup 51 can better adapt to the slight deformation of the long strip angle steel 1, or the uneven stacking angle, so as to ensure that the adsorption surface of the electromagnetic suction cup 51 can contact the angle steel 1 that needs to be destackered, so as to realize destacking on demand; through the matching of the positioning guide wheel 52 and the floating frame 5, the positioning guide wheel 52 can provide an alignment guide for the floating frame 5, so that the left and right staggered electromagnetic suction cups 51 can contact the middle part of the outer surface of the angle steel 1, so as to ensure the contact area between the electromagnetic suction cup 51 and the angle steel 1, thereby ensuring the adsorption quality, making the angle steel destacking operation safer and more reliable.

[0033] Among them, the left cross frame 21 is composed of two cross axes, which are parallel to each other, the right cross frame 22 has the same structure as the left cross frame 21, and the floating seat 3 is provided with two through-axis channels 31, which are matched with the cross axis, and the through-axis channels 31 are through holes, which are slidably matched with the cross axis, and the cooperation of the double axis and the double hole makes the movement of the floating seat more stable; the shock absorber 4 is a spring shock absorber, and the vertical limit mechanism 41 is arranged on the lower side of the spring of the spring shock absorber, and the vertical limit mechanism 41 is an adjustable nut, and the buffering margin of the shock absorber is adjusted by the adjustable nut; the angle between the action directions of the two electromagnetic suction cups 51 staggered on the left and right is 90 degrees can ensure that the two adjacent electromagnetic suction cups 51 are consistent with the outer structure of the angle steel, and the adsorption is more stable and safe during destacking; the positioning guide wheel 52 includes a connecting rod 521, and the connecting rod 521 is vertically slidably connected to the floating frame 5. The lower end of the connecting rod 521 is provided with a wheel frame 522, and the wheel frame 522 is equipped with a roller 523. A supporting spring is provided between the wheel frame 522 and the floating frame 5. The lower end of the electromagnetic suction cup 51 does not protrude from the lower end of the roller 523, ensuring that the roller 523 can preferentially contact the angle steel 1 to achieve the effect of guiding and positioning. The roller 523 is a ball bearing, which is easy to purchase and durable and reliable.

[0034] When in use, assemble the suction cup frame 2 with the lifting machinery, and hang the suction cup frame 2 above the stacked angle steels 1 so that the floating frame 5 is roughly parallel to the angle steel 1 to be destackered. The suction cup frame 2 is lowered by the lifting machinery, and the positioning guide wheel 52 first contacts the angle steel 1 to be destackered. Continue to lower the suction cup frame 2, and the spring of the positioning guide wheel 52 contracts to realize the guiding function. The electromagnetic suction cup 51 of the floating frame 5 can fully contact the angle steel 1. Open the electromagnetic suction cup 51 that needs to adsorb the angle steel 1, and lift the floating frame 5 to realize single destacking.

[0035] The suction cup frame 2 is suspended above the stacked angle steels 1 so that the floating frame 5 is roughly parallel to the angle steel 1 to be destackered, and the suction cup frame 2 is lowered by the lifting machinery. The positioning guide wheel 52 first contacts the angle steel 1 to be destackered, and the suction cup frame 2 is continued to be lowered. The spring of the positioning guide wheel 52 contracts to realize the guiding function. Under the action of the shock absorber, each floating frame 5 realizes flexible floating, until the electromagnetic suction cup 51 of each floating frame 5 can fully contact the corresponding angle steel 1, and the electromagnetic suction cup 51 that needs to adsorb the angle steel 1 is opened, and the floating frame 5 is lifted, so that the destacking of a single piece or a whole layer can be realized, which can well deal with the problems of different quantities in each layer of angle steel stacks, missing quantities, random stacking, and non-uniform specifications of angle steel stacks, resulting in different quantities in one layer, and height difference problems of stacking angle steels on the same layer.
