Description

Technical Field

[0001] The invention relates to the technical field of packaging machinery, in particular to a box-setting machine. Background Art

[0002] Carton packaging plays a very important role in the storage, transportation, and sales of goods. When the materials are processed on the production line, they need to be packaged with cartons at the end. For some square strip materials (such as slide rails), the packaging method is usually box-type packaging, that is, the carton is placed on the end of the material to form a package, and the gap between the carton and the material is generally small, so that the carton will be close to the surface of the material and not easy to slide off. Therefore, the size of the carton port is similar to that of the material end, which makes it difficult for existing cartoning machines to quickly and accurately put the carton on the end of the material. Summary of the invention

[0003] In order to overcome the defects in the prior art, the task of the present invention is to provide a box-sleeving machine which can quickly and accurately sleeve a paper box onto a material.

[0004] The task of the present invention is achieved through the following technical solutions:

[0005] A box-sleeving machine comprises a machine base, a material conveying mechanism arranged on the machine base, a carton feeding mechanism arranged on one side or both sides of the material conveying mechanism, and a box-sleeving mechanism arranged at the end of the carton feeding mechanism, wherein the box-sleeving mechanism comprises a carton pushing mechanism, a carton-sleeving guiding mechanism and a material positioning mechanism, wherein the carton-sleeving mechanism comprises a push plate and a first transverse movement mechanism for driving the push plate to move transversely, wherein the carton-sleeving guiding mechanism comprises a U-shaped guide cover with an opening facing downward, a first lifting mechanism for driving the guide cover to move up and down, and a second transverse movement mechanism for driving the first lifting mechanism to move transversely, wherein the guide cover comprises a cover body and an elastic cover protruding outward from one end of the cover body, wherein the elastic cover comprises a plurality of spring sheets inclined inwardly in a natural state, wherein the base of each spring sheet is respectively connected to the inner side wall of the cover body and is flush therewith, and the port of the elastic cover faces the carton-sleeving mechanism.

[0006] As a preferred technical solution, the material positioning mechanism includes a positioning plate and a second lifting mechanism that drives the positioning plate to move up and down.

[0007] As a preferred technical solution, the box guide mechanism further includes a guide channel fixedly arranged between the paper box ejection mechanism and the guide cover.

[0008] As a preferred technical solution, the material conveying mechanism includes a first material conveying mechanism, a stacking material sorting mechanism and a second material conveying mechanism arranged in sequence from front to back, the stacking material sorting mechanism includes a lifting frame, a limiting side plate, a support plate, and a third lifting mechanism for driving the lifting frame to move up and down, and the upper surface of the lifting frame is a slope inclined downward.

[0009] As a preferred technical solution, a fourth lifting mechanism for driving the lifting movement of the pallet is provided below the pallet.

[0010] As a preferred technical solution, the first material conveying mechanism includes a material conveying belt for conveying materials from front to back, and a limiting strip arranged above the material conveying belt.

[0011] As a preferred technical solution, the second material conveying mechanism includes a conveying channel, a U-shaped bracket with an upward opening arranged in the conveying channel, a fifth lifting mechanism for driving the bracket to move up and down, and a longitudinal movement mechanism for driving the fifth lifting mechanism to move forward and backward.

[0012] As a preferred technical solution, the carton supply mechanism includes a carton bin, a carton grabbing mechanism, a carton conveyor belt, and a paper folding and sealing mechanism arranged on the outside of the carton conveyor belt.

[0013] As a preferred technical solution, the carton conveyor belt is arranged below the carton bin, and the carton conveyor belt is composed of chains arranged in parallel. The latch teeth arranged at intervals on the two chains cooperate to form a carton bracket. The carton grabbing mechanism is located between the two chains and directly below the carton bin. The carton grabbing mechanism includes a suction cup and a sixth lifting mechanism for driving the suction cup to lift and lower.

[0014] As a preferred technical solution, the two side edges of the material conveying mechanism and the paper box feeding mechanism and the box-setting mechanism on the corresponding side edges are separately mounted on the base through frames, wherein at least one side of the frame is movably mounted on the base and can be driven to move laterally through a third transverse movement mechanism, thereby being able to adjust the distance between the frames on both sides.

[0015] During operation, the material conveying mechanism conveys the material to the box-setting station, and then the positioning pressure plate of the material positioning mechanism moves downward to press the material to position the material, and then the guide cover of the box-setting guide mechanism moves downward to cover the material, wherein the cover body covers the end of the material, and the elastic cover extends outward, and then the carton pushing mechanism pushes the carton located at the end of the carton feeding mechanism toward the end of the material until it is sleeved on the outside of the elastic cover. Since the spring pieces of the elastic cover are inclined inward, the carton port can be easily sleeved on the outside of the elastic cover, and then the guide cover and the material pushing mechanism move laterally synchronously. Since the spring pieces of the elastic cover are elastic, the elastic cover can expand outward and sleeve on the outside of the material end under the squeezing of the material end when it moves to the end of the material, and at the same time, the carton port is still sleeved on the outside of the elastic cover, and then the guide cover continues to move laterally and is pulled out from between the carton port and the material end, at this time, the carton is sleeved on the end of the material, and after the carton is completely sleeved on the end of the material, the material positioning mechanism, the guide cover, and the carton pushing mechanism are all reset, waiting for the next box setting.

[0016] Compared with the prior art, the box-sleeving machine of the present invention has the following advantages: ① By setting a box-sleeving guide mechanism, the box port and the material end can be quickly and accurately put on the material even if the sizes are similar; ② By setting a guide channel, when the box-pushing mechanism pushes the box to move, the box can be guided so that it can be accurately put on the outside of the elastic cover; ③ By setting a stacking and sorting mechanism, when the first material conveying mechanism conveys the material to the top of the lifting frame, the lifting frame moves upward to lift the material and flip it forward, so that multiple materials can be stacked and neatly stacked under the limiting action of the limiting side plate; ④ By setting a limiting strip, the material on the first material conveying mechanism can be limited; ⑤ By setting a U-shaped bracket, the bracket can be used to The U-shaped groove of the rack drags the material to the box-setting station and limits the material in the front and back directions. At the same time, the outer edge of the bracket can be used to drag the previously boxed material forward; ⑥ The cartons in the carton bin are generally pre-pressed cardboard. When the cardboard is grabbed by the suction cup and moved to the carton bracket formed by the cardboard teeth, the cardboard is formed into a carton under the action of the carton bracket, and then transported to the end by the carton conveyor belt. During the transportation process, the cover plate of the outer port of the carton is sealed under the action of the paper folding and sealing mechanism. There is no cover plate on the inner port of the carton, which is used to be sleeved on the end of the material; ⑦ By setting up a movable frame and a third transverse movement mechanism, the distance between the frames on both sides can be easily adjusted according to the length of the material, so that the box-setting machine has a wider range of application for materials.

[0027] like Figure 3 , 4 As shown, the box-setting mechanism 4 includes a carton pushing mechanism 41, a box-setting guiding mechanism and a material positioning mechanism. The carton pushing mechanism 41 includes a push plate 411 and a first transverse movement mechanism 412 for driving the push plate 411 to move laterally. The box-setting guiding mechanism includes a U-shaped guide cover 421 with an opening facing downward, a first lifting mechanism 422 for driving the guide cover 421 to move up and down, and a second transverse movement mechanism 423 for driving the first lifting mechanism 422 to move laterally. The guide cover 421 includes a cover body 4211, and an elastic cover 4212 protruding outward from one end of the cover body 4211. The elastic cover 4212 is composed of three spring pieces 42121 that are inclined inwardly in a natural state. The base of each spring piece 42121 is respectively connected to the upper, left and right inner walls of the cover body 4211 and is flush therewith. The port of the elastic cover 4212 is directly opposite to the carton pushing mechanism 41.

[0028] During operation, the material conveying mechanism 2 conveys the material 5 to the box-setting station, and then the positioning pressure plate of the material positioning mechanism moves downward to press the material to position the material, and then the guide cover 421 of the box-setting guide mechanism moves downward to cover the material, wherein the cover body 4211 covers the end of the material, and the elastic cover 4212 extends outward, and then the carton pushing mechanism 41 pushes the carton 6 located at the end of the carton feeding mechanism 3 toward the end of the material until it is sleeved on the outside of the elastic cover 4212. Since the spring pieces 42121 of the elastic cover 4212 are inclined inwardly, the carton port can be easily sleeved on the outside of the elastic cover 4212, and then the guide cover 421 and the material pushing mechanism are simultaneously The elastic cover 4212 moves laterally.
