Description

Technical Field

[0001] The invention relates to the field of plastic film production equipment, in particular to an automatic winding and transporting device. Background Art

[0002] After the existing film winding device completes the work of winding and unloading the film roll, the film roll needs to be packed manually. There are many patents about film winding devices in the prior art, such as:

[0003] The patent application with publication number CN109095238A discloses a PET film winder, including a frame and a guide roller assembly, a tension roller assembly, a slitting assembly, a traction roller assembly, a winding device, a film cutting device, a rolling pressing device and a turning device which are sequentially arranged on the frame. When the winder is working, the film is pulled by the traction roller assembly, passes through the guide roller assembly and the tension roller assembly in sequence, and then the thick edges on both sides are cut off by the slitting assembly, and then passes through the traction roller to enter the winding device for film winding to form a film roll. After the wound film roll is compressed by the rolling pressing device, the film is cut and the roll is changed by the film cutting device and the turning device.

[0004] For another example, the patent application with publication number CN111137724A discloses a CPP film winding machine, including a swing frame, a clamping assembly, a guide roller assembly, a trimming assembly, a traction roller assembly, a tension roller assembly, a floating roller assembly for controlling the flatness of the film winding, a flying knife assembly, a winding roller drive assembly, a roll changing assembly, an air shaft clamping and exhaust device, a roll unloading trolley, a roller device of an automatic film roll transfer device, a swing frame drive device, a linear displacement sensor, and a displacement detection device; the linear displacement sensor feeds back a signal to the roll unloading trolley so that the roll unloading trolley moves corresponding to the position of the swing frame when unloading the roll, so as to realize precise positioning of the roll unloading trolley and the air shaft.

[0005] Most of the current technical improvements are limited to the winder itself, and there are few changes to the subsequent packing process. The applicant has previously applied for a film unloading device for the winder, which can unload the film roll on the winder for transportation, but there is no improvement in the subsequent process. It still requires manual work to pack the unloaded film roll, and it is impossible to achieve full automation. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide an automatic winding and transporting device, which can automatically complete the film roll unloading, transport and boxing work, thereby greatly improving the degree of automation.

[0026] Example 1

[0027] As attached Figure 1 , 2 As shown, the automatic winding and transfer device of this embodiment includes a double four-station film winding machine 1, a paper tube conveyor belt 2, a paper tube loading device 3, a film roll unloading device 4, a roll unloading platform 5, a first conveyor belt 6, a second conveyor belt 7, a third conveyor belt 10, a material shifting device 8 and a robot 12.

[0028] The double four-station film winder 1 includes a wall panel 101 and two four-station winding devices arranged between the two wall panels 101. There are two four-station winding devices, which are installed in an upper and lower structure. The upper four-station winding device is close to the wall panel on one side, and the lower four-station winding device is close to the wall panel on the other side.

[0029] Specifically, the four-station winding device includes a positioning bar 102 arranged on the wall panel 101, a turntable 103 arranged on the positioning bar 102, and four air-expansion shafts 104 evenly arranged on the turntable 103. The air-expansion shafts 104 are provided with convex keys 106 for tightening the paper tube to fix it. The winding positions of the upper and lower four-station winding devices are staggered, and at the same time, the air-expansion shafts 104 are also staggered to a certain extent. Specifically, the winding positions on the air-expansion shafts 104 in each four-station winding device are the same, but the winding positions between the two four-station winding devices are relatively staggered and overlapped to a certain extent.

[0030] Under the premise of being equipped with a longer reel, for example, if the finished product is 2 meters long and the length of a single reel is 1200mm, the reeling positions on the two four-station reeling devices are staggered by 400mm. Even when an odd number of paper tubes are rolled at the same time, one of the paper tubes can be placed on an air expansion shaft at the staggered position. When rewinding, the die center and the reeling center can still be ensured to be on the same center line, thereby realizing the production of finished products with more width specifications.

[0031] If there is no staggered overlap, the length of the winding shaft of each four-station winding device is 1000mm, and the film width can only be evenly divided and wound on two winding devices. However, if the total width is slit into an odd number of specifications, for example, a total width of 2000mm is slit into 5 400mm wide pieces, it cannot be evenly divided on two 1000mm winding shafts, and products of this specification cannot be produced. At this time, the production specifications of the winding machine are relatively simple.

[0032] For example, if Figure 8 As shown, the structure of this embodiment can realize the production of multiple different regular combinations. The film can be rolled on 5 paper tubes at the same time on two four-station winding devices, or on 6 paper tubes at the same time, and the width of the paper tube can also be combined in multiple specifications.

[0033] In this embodiment, the length of the air expansion shaft 4 is 1200mm, and the staggered length is 400mm. When producing a film roll of 400mm×5 specifications, two paper tubes corresponding to the 400mm width film roll can be placed on the air expansion shafts of the two four-station winding devices, and the other can be installed on the upper four-station winding device or the lower four-station winding device, as long as the winding center of the five paper tubes is aligned with the center of the die head.

[0034] For another example, when producing film rolls of 500mm×2, 300mm×2, and 400mm×1, the paper tubes corresponding to the two 500mm width film rolls are installed on the air expansion shaft of a four-station winding device, and the other three paper tubes are installed on the air expansion shaft of another four-station winding device. Even if the number of paper tubes installed on the air expansion shaft in the two stations is inconsistent, due to the staggered winding positions, the position of the paper tube on the air expansion shaft can still be adjusted to ensure that the winding center is aligned with the center of the die head.

[0035] Figure 8 Other rule combinations in can still be produced according to the above principles.

[0036] Taking into account the influence of force, when slitting into an odd number of film rolls, it is preferred to place two paper tubes on the upper four-station winding device for production, and place three paper tubes on the lower four-station winding device for production, which will make the whole machine more stable.

[0037] The present embodiments are all based on examples of 2000mm finished products. In practice, 4500mm finished products can also be produced. In this case, the winding shaft is 2500mm long and the winding positions are staggered by 500mm. The principle is the same as that of the present embodiment. By analogy, finished products of other specifications can also be produced.

[0038] The paper tube conveyor belt 2 is arranged corresponding to the position where the air inflation shaft of the two four-station winding devices lifts up and passes through the paper tube, and an upper paper tube device 3 is provided on one side of the paper tube conveyor belt 2.

[0039] As attached Figure 3 , 4 As shown, the upper paper tube device 3 includes a frame 301, a paper basket 306 arranged on the frame 301, and a lifting device arranged on one side of the paper basket 306. There are two paper baskets 306 for placing paper tubes of different specifications, and the two paper baskets 306 correspond to a lifting device respectively. The top unloading position of the lifting device corresponds to the position of the paper tube conveyor belt 2, and the paper tube can be lifted from the paper basket 306 to the paper tube conveyor belt 2.

[0040] The lifting device includes a lifting chain 303 and lifting blocks 304 evenly arranged on the lifting chain 303. The lifting chain 303 is inclined, and also causes the lifting blocks 304 to be inclined. The bottom plate 302 of the paper basket 306 is also inclined. The paper tube can roll onto the lifting blocks 304 under the action of its own weight, so that it can move upward together with the lifting blocks 304.

[0041] Preferably, a protective cover 305 is provided on the top of the lifting device and above the paper tube conveyor belt 2.

[0042] Different paper tube loading devices are used to load paper tubes on the two four-station winding devices respectively, and each paper tube loading device can hold two paper tubes of different specifications, so as to realize the production of films with various widths and specifications.

[0043] There are two film unloading devices 4, which correspond to the two unloading positions of the double four-station film winder 1, and two unloading platforms 5 and first conveyor belts 6 are also provided correspondingly. The film roll 105 dropped from the film unloading device passes through the unloading platform 5 and falls onto the first conveyor belt 6. The film unloading device 4 adopts the existing patent structure, which will not be described here.

[0044] The first conveyor belt 6 is arranged on the first conveyor belt bracket, and a film roll baffle is arranged on its outer side to prevent the film roll from falling. At the same time, baffles are also arranged on both sides of the second conveyor belt 7 to also prevent the film roll from falling.

[0045] The second conveyor belt 7 is arranged between the two first conveyor belts 6, and the film rolls of the two first conveyor belts 6 are conveyed in opposite directions, both conveying toward the second conveyor belt 7. Through the forward and reverse reciprocating movement of the second conveyor belt 7, the film rolls on the two first conveyor belts 6 can be conveyed to the middle position of the second conveyor belt 7 corresponding to the material shifting device 8.

[0046] The material-discharging device 8 is located above the middle position of the second conveyor belt 7 , the third conveyor belt 10 is located on one side of the middle position, and the third conveyor belt 10 is perpendicular to the second conveyor belt 7 .

[0047] As attached Figure 5 As shown, the material diverting device 8 includes a material diverting gantry 801, baffles 802 arranged at the left and right ends of the gantry 801, and a material diverting plate 804 arranged at the middle position of the material diverting gantry 801, and the baffle 802 is connected to a lifting rod, and the material diverting plate 804 is arranged on a moving rod 803 which can move forward and backward.

[0048] The lifting timing of the baffle 802 of the material-dispensing device 8 should be coordinated with the movement direction of the first conveyor belt 6 and the second conveyor belt 7. The second conveyor belt 7 moves back and forth, and circulates left and right to transport the film rolls on the first conveyor belts 6 on both sides.

[0049] In actual use, according to the different material arrival timings of the two second conveyor belts 7, the baffle 802 on the corresponding side is lifted upwards. When a film roll enters between the two baffles 802, the baffle 802 falls down, so that a film roll is located between the two baffles 802. Then the material removal plate 804 moves to the side close to the third conveyor belt 10, pushing the film roll onto the third conveyor belt 10.

[0050] The robot 12 is located at the end of the third conveyor belt 10 and packs the film rolls on the third conveyor belt 10 .

[0051] Example 2

[0052] This embodiment is further improved on the basis of embodiment 1. Figure 1 , 6 As shown in Figures 7 and 8, a lifting device 9 is provided at the end of the third conveyor belt 10, and the lifting device 9 includes a material blocking plate 902 provided at the end of the third conveyor belt 10 and lifting plates 901 provided on the left and right sides of the third conveyor belt 10, wherein the material blocking plate 902 is provided above the third conveyor belt 10 and behind the lifting plates 901. When the film roll is transported to the position of the material blocking plate 902 by the third conveyor belt 10, the two lifting plates 901 move upward to lift the film roll for easy grasping by the robot.

[0053] Example 3

[0054] This embodiment is further improved on the basis of embodiment 1. Figure 1 As shown, a deflection push rod 11 is connected to the first conveyor belt 6, and the first conveyor belt 6 is installed on a first conveyor belt bracket. One end of the deflection push rod 11 is hinged to the base, and the other end is hinged to the first conveyor belt bracket.

[0055] The deflection push rod 11 enables the first conveyor belt 6 to have two working positions, one corresponding to the position of the unloading platform 5, and the other corresponding to the position of the second conveyor belt 7.
