The clamping mechanism 312 can clamp the edges or corners of the bag body, compatibility with various types of bag bodies is achieved, and the bag body can be clamped only in a limited mode. For example, different bag bodies have different expanding amplitudes, but the top edge or the bottom edge of the bag body can be clamped by a butt clamp, and similarly, any angle of the bag body can be clamped by the butt clamp, so that the special design is not required for the bag body under certain expanding conditions or large and small size conditions, the compatibility is greatly improved, and the clamping requirements of different bag bodies during bag breaking are met. The bag body is driven to move through the lifting component when the bag is broken, so that the bag breaking piece 332 can be used for breaking the bag body practically, and the materials are prevented from remaining in the bag body.

The rotation range H means that the operation such as clamping and releasing of the arm can be performed to cover the corresponding devices, for example, the bag breaking device 330 and the waste bag collecting device 500. It is not to be understood restrictively that these relevant devices must be completely within this range H in the view of fig. 3, i.e. the range of rotation H need not completely cover all the equipment in the view of fig. 3, but can also be functionally compatible with each device. By designing the position of the waste bag recycling device 500 and the position of the material collecting device 200, the space occupied by the whole automatic unpacking system 1000 is not large, and the site is saved. And through setting up useless bag recovery unit 500, can retrieve the empty bag after breaking open, avoid having the adnexed dust pollution operation environment on the empty bag.

And through further blowing, can make the bag body swell, more be favorable to dropping of material, reduced the material as far as possible and remain.

Referring to fig. 4, the lifting mechanism includes a vertical column 3221, a driving member 3222, and a lifting driving member 3223, the vertical column 3221 is connected to the lower supporting base 321, the driving member 3222 is disposed on the vertical column 3221 and connected to the suspension arm 311, and the lifting driving member 3223 drives the suspension arm 311 to lift and lower through the driving member 3222. Wherein, the lower supporting seat 321 includes a mounting seat 3211, a rotating electrical machine 3212 and a limit switch 3213, the bottom of the upright post 3221 is disposed on the mounting seat 3211, the rotating electrical machine 3212 and the limit switch 3213 are also disposed on the mounting seat 3211, and the rotating electrical machine 3212 can drive the top platform of the mounting seat 3211 to rotate through an intermediate structure such as a synchronous belt, so as to drive the upright post 3221 to rotate. A plurality of limit switches 3213 may be disposed on the mounting base 3211, and when the top platform of the mounting base 3211 triggers the limit switches 3213, the rotating electrical machine 3212 stops working, and starts again when a new command arrives. The lower supporting seat 321 can drive the cantilever 311 to rotate by driving the upright 3221 to move, the upright 3221 provides a lifting track for the lifting of the cantilever 311, and the cantilever 311 can be stably driven to move up and down by combining with the lifting driving member 3223.

In detail, the transmission member 3222 may be a timing belt or a chain. In this embodiment, a timing belt is used. The lifting driving member 3223 is a lifting motor, and the lifting motor drives the synchronous belt to rotate, so as to drive the cantilever 311 to lift on the upright 3221. The specific driving member 3222 may be selected according to the weight of the bag body or the stroke of the up-and-down movement, so as to meet the actual requirements. It is understood that a travel switch 32211 may be disposed on the pillar 3221 to facilitate the controller 100 to determine the height position of the cantilever 311.

Referring to fig. 6, the bag breaking member 332 in the present application is a knife. In the embodiment of fig. 6, two cutters are adopted in the embodiment to stand side by side, and when the bag body impacts the cutters from top to bottom, the bag body can be easily cut, so that the reliability of bag breaking is guaranteed. The cutting tools can be arranged in a crossed mode, for example, a cross structure is formed, or other shapes are crossed, a plurality of blades can be connected end to form a polygonal outline, or the cross structure and the end-to-end connection structure are used simultaneously, various patterns can be arranged according to bag breaking requirements, and the bag body can be broken.

That is, when the lifting unit drives the bag body and strikes downwards, the bag body can be effectively broken by the cooperation cutter, and the problem of bad bag breaking success rate is improved. It will be appreciated that the number and form of the cutters may be of other designs, such as increasing or decreasing the number, the cutters may be straight or toothed or curved, etc. Or the bag breaking piece can be designed into a thick prick, so long as the bag body can be punctured and a large-caliber crevasse is formed when the bag body is impacted. It should be understood that the knife or the pricker of the present application are only examples, and any sharp object with a sharpness enough to break the bag body may be used as the bag breaking member.

Alternatively, in some other embodiments, the bag breaking member 332 is liftably disposed on the bag breaking cylinder 331 to move toward the cantilever 311. The bag breaking member 332 is designed to be liftable, so that the bag breaking success rate can be improved in an auxiliary manner. Optionally, the bag breaking piece 332 can be designed to move circumferentially around the bag breaking cylinder 331, when the bag body is brought into the range of the bag breaking cylinder 331 by the lifting assembly, the bag body can be cut through a circular cutting mode, the bag breaking success rate is guaranteed, at the moment, the bag body can be lowered without accelerating impact, and the bag can be broken through the movement of the cutter by only reaching the side of the cutter.

In this embodiment, a top cap 3311 made of a flexible material such as cloth is fixed to the upper end of the bag breaking cylinder 331, and a hole is formed in the top cap 3311 to allow a part of the bag to pass through and strike a cutter. By arranging the top cover 3311, a certain buffer can be formed, and the falling position of the bag body can be conveniently determined. And also to avoid the hard cap 3311 from being crushed or the cantilever 311 from being damaged by a reaction force.

Alternatively, the shape of the bag breaking cylinder 331 may be other than the cylindrical shape shown in the drawing of the present embodiment, as long as the knife can be easily set up, and the bag body can be broken to block the popped material in the circumferential direction, thereby preventing the material from escaping in a large amount, and guiding the material to the lower space.

Referring to fig. 1, the unpacking device 300 in the present application further includes a dust removing device 340, and the dust removing device 340 is connected to the bag breaking cylinder 331 and can suck dust in the bag breaking cylinder 331. The dust removing device 340 can be in a negative pressure adsorption mode, so that the bag breaking process becomes dustless, and the working environment of a workshop is not affected by bag breaking. When the dust remover is used, micro negative pressure dust removal is generally adopted, so that dust removal can be guaranteed, and light materials can be prevented from being sucked away as far as possible.

The principle of the embodiment is as follows:

the lifting assembly can drive the cantilever arm 311 to descend, clamp the bag body at the feeding position, then raise and rotate by the driving of the lower support seat 321, for example, can rotate 90 degrees, and at this time, the bag body is aligned with the cutter on the bag breaking cylinder 331.

The lifting motor is driven reversely, so that the bag body is driven by the cantilever 311 to be rushed downwards at an accelerated speed and collide with the cutter, and the bag body can be broken by the sharp cutter. At this time, the dust removing device 340 works synchronously to realize dustless bag breaking process.

Then the cantilever 311 can move up and down under the driving of the lifting motor, and under the cooperative cooperation of the stroke switches 32211, the cantilever 311 can move back and forth in different height ranges, so as to shake the bag body. Through shaking the bag body, can improve the material from the internal exhaust efficiency of bag, can also shake out the material as far as possible simultaneously, like people carry the plastic bag and lead to the nothing in the bag and shake out.

Then the cantilever 311 is lifted again, and the lower supporting seat 321 drives the upright 3221 to rotate 90 ° further, so that the bag body is located above the waste bag recycling device 500. The gripper 312 releases the bag to be collected.

Finally, the lower support 321 and the lifting assembly are driven again, so that the cantilever 311 returns to the initial position for the next operation.

It can be seen that the above operations are completed within the movement track of the cantilever 311, and the overall occupied area is smaller than that of a common unpacking device, thereby saving the factory. And because simple structure, in the process of maintenance and daily clearance, it is all more convenient. And through driving the bag body to descend with higher speed, originally sharp basis at the cutter, further increased the pressure of contact position for the bag body can be broken more easily. After the bag body contacts the cutter, the cantilever 311 still has a descending space, so that the pressure between the two can be increased again, the cutter can be ensured to break the bag body instantly, and the material can fall down smoothly.

The material residue in the bag body can be further reduced by combining the shaking action. The bag body is simply scratched to prior art, and the material is lower from the internal exhaust efficiency of bag, and this application then can improve efficiency through the shake, does benefit to production. In addition, material residue can be reduced, great loss of materials is avoided, and certain benefits are achieved for reducing production cost. Meanwhile, as the residual materials in the bag body are less, when the waste bag body is moved away, the material leakage and the pollution to the production environment can be avoided to a certain degree. And dust collector 340 is removing dust all the time at little negative pressure, can avoid the workshop by dust pollution, when the guarantee personnel are healthy, can not too much suck the material again, reduces the loss of material.

Whole process can manual control also can automated control, and whatever kind of mode, compare in ordinary unpacking operation, all more efficient, and reduced artifical intensity of labour.

To sum up, the unpacking device 300 of the application can clamp the bag body through the cantilever bag clamping device 310, has no limitation on the size and the appearance of the bag body, can clamp edges or corners, is good in compatibility, and can drive the bag body to accelerate the bag breaking piece 332 colliding with the bag breaking device 330 in combination with the driving of the rotary lifting mechanism 320, so that the bag breaking success rate is high, and the existing problem is effectively improved. In combination with the controller 100, an automatic unpacking system 1000 can be formed, so that the bag breaking efficiency is further improved, and the labor is saved.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art.
