Description

Technical Field

[0001] The invention relates to the field of pipe packaging, and in particular to an automatic pipe packaging machine. Background Art

[0002] At present, domestic pipe packaging machines are gradually adopting automated packaging machines to replace traditional manual packaging, which improves the overall production efficiency of the equipment. Since the packaging of pipes requires two necessary processes, film wrapping and bagging, the existing pipe packaging machines set the winding mechanism and the bagging mechanism on the same horizontal axis for continuous processing. Although the running speed of the whole machine can be improved to a certain extent, the winding and bagging are two separate stations, which makes the packaging machine generally a two-section machine, occupying a large plant space, and the passage left between the packaging machines is narrow. At the same time, a pusher trolley is needed to transfer the pipe between the winding mechanism and the bagging mechanism. Only after the pipe is wrapped can it be bagged. The packaging process is: the pipe is wrapped on the winding mechanism, and then the pusher trolley transfers the pipe after film wrapping to the bagging mechanism for bagging. After the bagging is completed, the pusher trolley transfers the pipe to the next process. It takes a certain amount of time for the pusher trolley to carry out the cumbersome transfer process during the packaging process of the pipe, which makes it difficult to greatly improve the overall running speed of the packaging machine and cannot cooperate with the high-speed pipe extrusion device.

[0028] Reference Figure 1 to Figure 7 Taking the pipe packaging equipment using PVC packaging bags as an example, the present invention makes the following embodiments:

[0029] like Figure 1 and Figure 2 As shown, the rack 1000 includes a rack 1000, on which a trustee mechanism 100, a pipe feeding mechanism 200, a wrapping bagging device 300, a sealing mechanism 400, and a lifting mechanism 500 are arranged. The above mechanisms cooperate to package the pipes. There are multiple trustee mechanisms 100, and the multiple trustee mechanisms 100 are arranged at intervals along the left and right directions at the bottom of the rack 1000. The trustee mechanism 100 is used to control the orderly arrangement of the pipes. The pipe feeding mechanism 200 is arranged at the front side of the rack 1000, and the pipe feeding mechanism 200 is arranged above the trustee mechanism 100. The pipe feeding mechanism 200 is used to arrange the pipes to be packaged into the trustee mechanism 100. 0 is provided with a winding and bagging device 300 at the right end of the bottom, and the winding and bagging device 300 is slidably arranged on the frame 1000 along the left and right directions. The winding and bagging device 300 comprises a winding mechanism 310 and a bagging mechanism 320, and the winding mechanism 310 and the bagging mechanism 320 are used to wrap the film and bag the pipe, so as to facilitate the sequential wrapping and bagging of the pipe. The winding mechanism 310 and the bagging mechanism 320 are located on the same horizontal axis, and the trustee mechanism 100, the winding mechanism 310 and the bagging mechanism 320 are sequentially arranged at the bottom of the machine from left to right, and the trustee mechanism 100 includes a trustee slot, and the through holes for the pipe to pass through the trustee slot, the winding mechanism 310 and the bagging mechanism 320 are coaxially arranged.

[0030] It can be understood that in order to cooperate with the left and right sliding of the wrapping bag device 300, the trusteeship mechanism 100 can be raised and lowered, and the sliding of the wrapping bag device 300 is intermittent. When the wrapping bag is paused, the tube is wrapped with film. When the wrapping bag is completed, the wrapping bag device 300 slides to the left to bag the tube. When the wrapping bag device 300 slides left and right, in order to avoid collision with the trusteeship mechanism 100, the trusteeship mechanism 100 closest to the wrapping bag device 300 will move downward along the trajectory direction of its left and right sliding to wrap the tube. The sliding of the bagging device 300 provides a sliding space. A sealing mechanism 400 is provided above the wrapping bagging device 300. The sealing mechanism 400 is relatively arranged at the left and right ends of the frame 1000. The sealing mechanism 400 includes two heat-sealing plates arranged in front and back. The two heat-sealing plates can be driven by cylinders to move relative to each other to heat-seal the PVC packaging bag. In order to transport the pipe material along the up and down direction of the frame 1000, a lifting mechanism 500 is also provided on the frame 1000. The lifting mechanism 500 and the pipe feeding mechanism 200 are respectively arranged at the rear side of the frame 1000. On the front side, the lifting mechanism 500 includes a pipe unloading assembly 510 and a lifting assembly 520. The pipe unloading assembly 510 is arranged above the sealing mechanism 400, and the lifting assembly 520 is arranged at the bottom of the frame 1000. The lifting assembly 520 can be lifted up and down, and the lifting assembly 520 is used to transport the pipe material to the sealing mechanism 400. The present invention combines a winding mechanism 310 and a bagging mechanism 320 to form an integrated winding and bagging device 300, thereby realizing the continuous processing of winding and bagging at the same workstation, and can utilize the sliding of the winding and bagging device 300 itself to perform winding and bagging simultaneously. Not only does it not require a pushing trolley to perform tedious transfer operations between winding and bagging, but it also greatly improves the operating speed of the entire machine, can cooperate with a high-speed pipe extrusion device, and is conducive to shortening the overall length of the pipe packaging machine, making it convenient to shorten the two-section machine into one-section machine, thereby reducing the site space occupied by the packaging machine.

[0031] Among them, refer to Figure 3The wrapping bagging device 300 is slidably arranged on two sets of first linear guide rails 330, and the two sets of first linear guide rails 330 are arranged parallel to each other at the bottom of the frame 1000 along the front and back. The multiple trusteeship mechanisms 100 are arranged on the inner side of the two sets of first linear guide rails 330. The right ends of the two sets of first linear guide rails 330 are provided with first mounting seats 340. The front and rear sides of the bottom of the first mounting seat 340 are oppositely provided with two first sliders. The four first sliders are relatively sleeved on the two sets of first linear guide rails 330. The wrapping mechanism 310 and the bagging machine The structure 320 is fixedly connected to the first mounting seat 340, that is, the sliding of the wrapping and bagging device 300 in the left and right directions is realized, and the wrapping process and the bagging process are located at the same workstation, so that the wrapping mechanism 310 and the bagging mechanism 320 can realize synchronous sliding on the two sets of first linear guide rails 330 along with the first mounting seat 340, so that the film wrapping process and the bagging process can be carried out simultaneously and continuously. Compared with separating the wrapping process and the bagging process at two workstations, the operating speed of this embodiment is greatly improved, and the packaging efficiency is higher.

[0032] Furthermore, first transmission chains 350 are arranged on the outer sides of the two groups of first linear guides 330, and the first transmission chains 350 are arranged in parallel with the first linear guides 330. The two groups of first transmission chains 350 are respectively fixedly connected to the first mounting seat 340 through the connecting seat 360, and each group of first transmission chains 350 is tensioned on the first transmission sprocket and the first driven sprocket 380. The first driving sprocket 370 is arranged at the left end of the first transmission chain 350, and the first driven sprocket 380 is arranged at the left end of the first transmission chain 350. 50, the first driving sprocket 370 arranged on the same side is connected through the first driving shaft, and the first driven sprocket 380 arranged on the same side is connected through the first driven shaft. The first driving shaft is provided with a driving motor and a reducer. The first transmission chain 350 can drive the winding bag mechanism 320 to slide left and right on the first linear guide rail 330 through the connecting seat 360. The transmission mode of the winding bag device 300 can be selected from belt drive and chain drive. In the embodiment of the present invention, chain drive is selected, which has high transmission accuracy and fast running speed.

[0033] In some embodiments, in order to push the pipe in the trusteeship mechanism 100 into the wrapping bagging device 300, a second mounting seat 610 is slidably provided at the left end of the two sets of first linear guide rails 330, and a pipe-pushing mechanism 600 is provided on the second mounting seat 610, that is, the pipe-pushing mechanism 600 can slide left and right along the first linear guide rail 330, and the pipe-pushing mechanism 600 includes a first pipe-pushing assembly. The first pipe-pushing assembly includes a telescopic rod 601, which extends in the left and right directions, and the telescopic rod 601 is driven by a cylinder. It can be extended left and right, and a first tube jacking plate 602 is provided at the right end of the telescopic rod 601. Under the action of the telescopic rod 601, the first tube jacking plate 602 pushes the pipes in the trusteeship mechanism 100 into the winding bagging device 300. The telescopic rod 601 can be used for tube jacking of pipes of different lengths. When the first tube jacking plate 602 is used for tube jacking, the pipes can be pushed to be aligned. When in use, the first tube jacking plate 602 contacts one end of the pipe, and the telescopic rod 601 is extended to push the pipe into the winding bagging device 300.

[0034] Furthermore, since the first top tube plate 602 needs to pass through the second through hole of the film clamp when the wrapping bag device 300 slides to one end of the top tube mechanism 600, the cross-sectional area of ​​the first top tube plate 602 should not be too large. In order to meet the needs of pipes with larger cross-sectional areas, the top tube mechanism 600 includes a second top tube assembly, which is arranged on the right side of the first top tube assembly. The second top tube assembly includes a second top tube plate 603, which is in contact with the right side surface of the first top tube plate 602. The cross-sectional area of ​​the second top tube plate 603 is larger than that of the first top tube plate 602. The second top tube plate 603 can be raised and lowered. When the cross-sectional area of ​​the tube to be packaged is larger than that of the first top tube plate 602, the second top tube plate 603 rises, and the first top tube plate 602 presses against the left side of the second top tube plate 603 to provide support for the second top tube plate 603. The first top tube plate 602 and the second top tube plate 603 cooperate in pipe pushing. The cross-sectional areas of the first top tube plate 602 and the second top tube plate 603 can be circular or polygonal.

[0035] Specifically, a hinge shaft is provided on the right side of the second mounting seat 610, and the hinge shaft is arranged along the front and rear. Connecting rods are fixedly provided on the front and rear sides of the second top tube plate 603 respectively. The two connecting rods are hinged to the second mounting seat 610 through the hinge shaft. A cylinder is provided at the bottom of the second mounting seat 610. The output shaft of the cylinder is connected to the second top tube plate 603, which can drive the second top tube plate 603 to swing left and right around the hinge shaft.

[0036] In some embodiments, reference Figure 4The lifting assembly 520 includes a plurality of second linear guide rails 521 extending in the up-down direction, and a second transmission chain 522 is correspondingly provided on one side of each second linear guide rail 521, and the second transmission chain 522 is tensioned on the second driving sprocket 523 and the second driven sprocket 524. A third mounting seat 525 is provided between each second linear guide rail 521 and the corresponding second transmission chain 522, and the third mounting seat 525 is fixedly connected to the second transmission chain 522, and the third mounting seat 525 is slidably connected to the second linear guide rail 521, that is, the second transmission chain 522 can be driven The third mounting seat 525 slides up and down along the second linear guide rail 521. The third mounting seat 525 is provided with a side posture cylinder. The output shaft of the side posture cylinder is connected to a supporting plate 526. The side posture cylinder can drive the supporting plate 526 to swing left and right. The supporting plate 526 is provided with a supporting groove, which is used to accommodate the pipe. The initial state of the supporting plate 526 is a left and right extension state. When the pipe bagging is completed, the side posture cylinder drives the supporting plate 526 to swing to a front and back extension state, which is used to control the orderly arrangement of the pipes. At this time, the pipes are transported to the sealing mechanism 400 for sealing through the second transmission chain 522.

[0037] Furthermore, the pipe unloading assembly 510 includes a rotating shaft 511, which is arranged on the upper side of the frame 1000, and the rotating shaft 511 extends left and right. A plurality of pipe unloading hooks 512 are fixedly penetrated on the rotating shaft 511, and the plurality of pipe unloading hooks 512 are arranged at intervals left and right. The rotating shaft 511 can drive the pipe unloading hooks 512 to swing up and down, and a pipe unloading slide is arranged on the rear side of the pipe unloading hook 512. The pipe unloading hook 512 swings upward to discharge the pipe onto the pipe unloading slide, and the pipe unloading slide is arranged to tilt downward from front to back, and the pipe can be unloaded into the storage rack along the pipe unloading slide. In order to stably unload the pipe on the pipe unloading hook 512 and prevent it from rolling down, The pipe unloading hook 512 is provided with a first curved groove and a second curved groove from top to bottom. The groove depth of the first curved groove is greater than that of the second curved groove. A protrusion is provided on the upper side of the second curved groove. When the pipe is unloaded along the pipe and the pipe is sealed, the pipe is supported in the first curved groove. When the sealing is completed, the pipe unloading hook 512 continues to swing upward, and the pipe rolls from the first curved groove to the second curved groove. The pipe slides along the protrusion onto the pipe unloading slide plate 513. The setting of the protrusion can prevent the pipe from being stuck and ensure the smoothness of pipe unloading. Due to the limitation of the internal space of the frame, the pipe unloading assembly occupies less space than the grabbing type pipe unloading mechanism.

[0038] Specifically, the working principle of the present invention is as follows: in the first step, the pipes to be packaged are arranged in the trusteeship mechanism 100 through the pipe feeding mechanism 200; in the second step, the pipe pushing mechanism 600 pushes the pipes in the trusteeship mechanism 100 to the right into the wrapping and bagging device 300, and the wrapping and bagging device 300 intermittently slides to the left along the two sets of first linear guide rails 330 to wrap and bag the pipes. When the wrapping and bagging device 300 slides, the trusteeship mechanism 100 moves downward in sequence along the sliding direction of the wrapping and bagging device 300; in the third step, the lifting component 520 of the lifting mechanism 500 transports the pipes to the sealing mechanism 400, and when the pipes are sealed, the pipe unloading component 510 of the lifting mechanism 500 holds the pipes, and the lifting component 520 Descending, specifically, first, the side cylinder drives the supporting plate 526 to swing to the bottom of the pipe, and then, the second transmission chain 522 drives the second mounting seat 610 to slide upward, that is, to lift the pipe upward. When the pipe is lifted to the sealing mechanism 400, the rotating shaft 511 rotates to make the pipe unloading hook 512 swing upward to the bottom of the pipe. At this time, the lifting assembly 520 moves downward, and the pipe is supported on the pipe unloading hook 512. The two heat-sealing plates of the sealing mechanism 400 move relative to each other to heat-seal the two ends of the packaging bag; in the fourth step, after the sealing mechanism 400 completes the sealing, the rotating shaft 511 drives the pipe unloading hook 512 to swing upward again, and the pipe is arranged on the pipe unloading slide. The pipe slides along the pipe unloading slide into the storage rack to complete the pipe unloading.

[0039] In some embodiments, reference Figure 5 The winding mechanism 310 includes an annular rotating disk 311 and an annular driven gear 312 arranged side by side. A film material assembly 313 is provided on the left side of the annular rotating disk 311. The film material assembly 313 is used to provide film material for film wrapping. A film pulling assembly 314 is provided on the inner side of the annular rotating disk 311. The film pulling assembly 314 is used to cut the film material. A transmission bearing 315 is provided between the annular rotating disk 311 and the annular driven gear 312. The outer ring of the transmission bearing 315 is fixedly connected to the first mounting seat 340. The annular rotating disk 311 is connected to the left side of the inner ring of the transmission bearing 315. The annular driven gear 312 is connected to the right side of the inner ring of the transmission bearing 315. The outer circumference of the annular driven gear 312 is meshed and connected There is a driving gear, and multiple driving gears can be set. The driving gear is driven to rotate by a motor. The middle parts of the annular rotating disk 311, the annular driven gear 312 and the transmission bearing 315 are all provided with a first through hole for the pipe to pass through. The annular rotating disk 311, the annular driven gear 312 and the transmission bearing 315 are coaxially arranged. The transmission bearing 315 is arranged between the annular rotating disk 311 and the annular gear. The transmission bearing 315 is used to guide the annular rotating disk 311. Compared with the use of groove guidance, the guidance is more stable, and the annular rotating disk 311 will not swing. The annular rotating disk 311 can be stopped at the same position after each film wrapping is completed, which is convenient for the detection device to accurately detect the film material and ensure the stable film wrapping.

[0040] Among them, the film material assembly 313 includes a film roll and multiple guide rollers. The film roll is used to store the film material, and the guide rollers are used to tension and guide the film material. After the film material is pulled out from the film roll, it passes around the multiple guide rollers in sequence, which can prevent the film roll from idling. At the same time, in order to maintain the stability of the center of gravity of the annular rotating disk 311 and ensure the smooth rotation of the annular rotating disk 311, a balancing weight block is also provided on the left side surface of the annular rotating disk 311. The film material assembly 313 and the balancing weight block are respectively arranged on the front and rear sides of the annular rotating disk 311 to form a weight balance. The film-drawing assembly 314 includes a film-drawing seat, on which a film-drawing cylinder, a film-drawing rod connected to the film-drawing cylinder, and a heating wire are arranged. The film-drawing rod and the heating wire are both arranged on the left side of the film-drawing seat. The film-drawing rod can be extended left and right. A film hook ring is arranged at the left end of the film-drawing rod. The film hook ring is used to hook the film material to the heating wire so that the film material can be melted by the heating wire. In order to detect the winding condition of the film material, a photoelectric eye is also arranged on the left side of the film-drawing seat. The photoelectric eye is arranged between the film-drawing rod and the film material assembly 313, and the film-drawing rod is arranged on the photoelectric eye. When the photoelectric eye detects the film material, the heating wire is controlled to heat up. When the winding mechanism 310 is wrapping the film, the film pulling rod is in a contracted state. When the film wrapping is completed, the film pulling cylinder drives the film pulling rod to extend and then retract. The film hook ring on the film pulling rod pulls the film material to the heating wire. The film material is melted after touching the heating wire, and the film material is cut off. The remaining film material end is wrapped around the film hook ring of the film pulling rod. The film material is still in a tensioned state, which is convenient for the next film wrapping. There is no need to manually fix the film material end on the pipe.

A guide rod 730 is fixedly connected to the left side of the guide head 710, and a front slide plate 740 is provided at the left end of the guide rod 730. The front slide plate 740 is inserted into the second through hole. It should be understood that when the jacking mechanism 600 pushes the pipe to the right, the pipe is pushed to the front slide plate 740, and the guide A guide wedge 750 is provided on the right side of the head 710, and rollers are provided on the upper and lower sides of the guide wedge 750 and the lower side of the guide head 710. An adjusting screw 760 is provided between the guide head 710 and the guide wedge 750. The guide mechanism 700 is used to open the mouth of the packaging bag and guide the packaging bag between the roll-type packaging bag storage cylinder and the bagging mechanism 320, thereby improving the manual grasping of the packaging bag and opening the bag mouth, and improving the operation efficiency. When in use, the packaging bag will not be wrinkled between the guide head 710 and the limiting roller 720. The front and rear sides of the guide head 710 are relatively provided with limiting grooves, and the limiting grooves are correspondingly matched with limiting rollers 720, which can be stuck in the limiting grooves to lock the packaging bag. It can be understood that a cutting mechanism is provided between the guide mechanism 700 and the bagging mechanism 320 for cutting the packaging bag.

The embracing mechanism 390 includes a trusteeship plate 391 and two clamps 392. The middle part of the trusteeship plate 391 can be used for the pipe to pass through. When the first mounting seat 340 slides left and right, in order to avoid it from colliding with the trusteeship mechanism 100 that is set closest to it, the trusteeship mechanism 100 will be lowered under the pipe. At this time, the trusteeship plate 391 replaces the trusteeship mechanism 100 to control the orderly arrangement of the pipes. The two clamps 392 are arranged in a front-to-back manner, and the two clamps 392 are arranged between the hosting plate 391 and the winding mechanism 310. The two clamps 392 are respectively connected to the output shaft of the first cylinder. The two first cylinders can respectively drive the two clamps 392 to move forward and backward. The front-to-back relative movement of the two clamps 392 is used to clamp and release the pipe. When the two clamps 392 are repeatedly tightened and loosened relative to each other, the pipe can be arranged in order by shaking the pipe. It can be understood that when the winding mechanism 310 is working, the two clamps 392 cooperate to clamp the pipe. When the film wrapping is completed, the two clamps 392 are released, the first mounting seat 340 slides to the left, and the bagging mechanism 320 bags the pipe.
