[0001] The invention relates to the technical field of PVC film stacking, in particular to a stacking device for PVC film production. Background Art

[0002] After the PVC film is produced and rolled, in order to facilitate its overall packaging, transportation and warehousing, a palletizing production line will be set up to stack the formed PVC film rolls neatly from bottom to top, thereby achieving stable positioning of the PVC film rolls, facilitating access, and avoiding scratches and damage caused by scattering and overlapping of PVC film rolls. When implementing the stacking operation of PVC film rolls, in order to improve the stacking efficiency, a matching conveyor line will be set up to facilitate the stacking robot in the stacking operation to pick up goods.

[0003] The stacking and stacking of existing PVC film production, in order to facilitate the stable picking of goods by the stacking robot and prevent wrong grasping or unstable gripping, the PVC film rolls are manually or assisted sorted before transportation, so that the PVC film rolls are actively sorted in advance during the transportation process, thereby ensuring that the PVC film rolls do not scatter during transportation and avoiding the damping between the PVC film rolls due to mutual stacking, which affects the stability of transportation; however, in actual use, since the PVC film rolls are batched when stacking, individual PVC film rolls are actively sorted and stacked before transportation, which has low operation efficiency and requires auxiliary stacking participation, which greatly affects the efficiency of stacking and warehousing. At the same time, after active sorting, they are stacked on the conveying device, which may cause the PVC film rolls to scatter and obstruct each other during the transportation and stacking process due to external factors such as improper operation and the rolling external force of the PVC film rolls on the conveyor belt. The PVC film rolls are piled up on each other during transportation, causing damage to the PVC film rolls.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original stacking and stacking device for PVC film production. Summary of the Invention

[0005] The purpose of the present invention is to provide a stacking and stacking device for PVC film production to solve the problem that the existing stacking and stacking device for PVC film production proposed in the above background technology requires auxiliary stacking, which greatly affects the efficiency of its stacking and warehousing. At the same time, due to external factors such as improper auxiliary operation, the PVC film rolls may be scattered and blocked during the transportation and stacking process, causing damage to the PVC film rolls.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a stacking device for PVC film production, comprising a conveyor belt assembly, a lifting assembly, and a stacking assembly, which are sequentially distributed from right to left, to realize the conveying and stacking of PVC film rolls; The conveyor belt assembly also includes: a conveyor belt assembly, the top surface of which is provided with a 5% slope opposite to its conveying direction, and the width of the conveyor belt assembly is greater than the length of the PVC film roll. At the same time, a one-way limiter is provided on the conveyor belt of the conveyor belt assembly to limit the rolling of the PVC film roll, and a combing device and a limiter are provided in the middle section of the conveyor belt assembly to realize the arrangement of scattered PVC film rolls; The carding frame is installed in a lifting manner below the carding device, and a rotating frame is symmetrically installed on the carding frame. The rotating frame realizes the centering and positioning of the PVC film roll through the elastic airbag on it.

[0007] Preferably, a blocking plate is fixed at the discharge position of the PVC film roll on the conveyor belt assembly, and the blocking plate is funnel-shaped to prevent the PVC film roll from falling and facilitate the discharge of the PVC film roll.

[0008] Preferably, the one-way limiter includes a positioning piece embedded and fixed on the conveyor belt, on which a damping pressure plate is rotatably mounted. The damping pressure plate is used to limit the PVC film roll, and an elastic member is installed between the damping pressure plate and the positioning piece.

[0009] Preferably, the contact surface between the damping pressure plate and the PVC film roll is made of damping rubber material, and the direction of the damping pressure plate's rotational compression deformation is the same as the 5% slope direction of the conveyor belt, wherein the combined maximum elastic force of the elastic parts maintains balance with the gravity of a single PVC film roll.

[0010] Preferably, an electromagnet is also fixed on the positioning plate, which corresponds to the permanent magnet on the back of the damping pressure plate and is arranged with like poles repelling each other. When the one-way limiter moves to the vertical projection surface and the left side of the comber, the electromagnet limits the damping pressure plate by repelling the permanent magnet.

[0011] Preferably, the turrets are symmetrically arranged on the combing frame and about their vertical coaxial lines, the two turrets rotate synchronously and in different directions, and the turrets and the elastic airbags are also arranged in a relative rotation structure.

[0012] Preferably, a toothed disc coaxially distributed with the rotating axis of the rotating frame is further provided at the bottom of the combing frame, and the outer wall of the toothed disc is meshed with the gear at the top shaft end of the elastic airbag.

[0013] Preferably, the elastic airbag utilizes the rotating frame driving position, as well as its own rotation and elastic compression deformation external force to achieve the centering of the PVC film roll, and a raised rubber strip is provided on the outside of the elastic airbag, which is weakly adhered to the outer wall of the PVC film roll.

[0014] Preferably, the limiter is arranged on the left and right sides of the conveyor belt assembly, and the limiter includes a positioning plate fixed on the conveyor belt assembly, and a movable baffle positioned on the positioning plate by bolts, wherein the movable baffle and the positioning plate are respectively provided with a brush and a ball.

[0015] Preferably, the spacing between adjacent positioning plates is smaller than the length of the PVC film roll, wherein the top surface of the positioning plate is used to receive both ends of the PVC film roll, and the obliquely arranged brush is oriented in the same vertical direction as the conveyor belt assembly.

[0016] Compared with the prior art, the present invention has the following beneficial effects: the stacking and stacking device for PVC film production can improve the stability and efficiency of cargo grabbing when stacking PVC film rolls, and at the same time, it is not necessary to actively place the PVC film rolls neatly before transporting and stacking, thereby realizing automated production line-type stable stacking. The specific contents are as follows: 1. The conveyor belt assembly, lifting assembly and stacking assembly are used to complete the entire set of PVC film roll transportation, lifting and stacking. During stacking, the conveyor belt assembly automatically arranges the PVC film rolls in transit, which speeds up the stacking efficiency and avoids problems such as difficulty in grabbing the stacking gripper and unstable grabbing during the stacking process. Furthermore, the slope and one-way limiter auxiliary settings of the conveyor belt assembly enable the PVC film roll to be placed directly on the conveyor belt assembly. When the conveyor belt assembly is conveying, the PVC film roll rolls due to the slope and automatic gravity. Under the action of the one-way limiter, a single PVC film roll is conveyed away by the conveyor belt assembly, while multiple superimposed PVC film rolls are deformed and compressed due to gravity pressure, thereby preventing the stacking and squeezing of the PVC film rolls during transportation. Furthermore, by setting up a combing device, it utilizes the combing frame, rotating frame and elastic airbag on it to center and sort the PVC film roll when it is conveyed but discharged in a displaced position, so as to prevent the displaced PVC film roll from being scattered and rolling and stacking due to friction resistance and its own stability during continuous conveying, and accumulating on the conveyor belt to affect subsequent stacking operations.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1-11The present invention provides a technical solution: a stacking and stacking device for PVC film production, comprising a conveyor belt assembly 1, a lifting assembly 2 and a stacking assembly 3, which are sequentially distributed from right to left, to realize the conveying and stacking of PVC film rolls; in the above technical solution, after the PVC film roll is placed on it, it is conveyed from right to left by the conveyor belt assembly 1. When it is conveyed to the position of the lifting assembly 2, the lifting assembly 2 conveys the PVC film roll from the conveyor belt assembly 1 to the transfer platform 301. The transfer platform 301 is located between the stacking assembly 3 and the top of the lifting assembly 2. Then, the lifting arm 303 on the stacking assembly 3 is lifted and lowered, driving the telescopic The arm 304 changes the positioning height. Under the synchronous action of the telescopic arm 304 and the movably connected stacking gripper 305, the PVC film roll on the transfer platform 301 is taken and placed to complete the stacking of the PVC film roll. The operation is convenient, and the PVC film roll is directly placed on the conveyor belt assembly 1 for transportation. There is no need for auxiliary dynamic adjustment of the stability of the PVC film roll placement. The PVC film roll can be automatically sorted, adjusted and positioned when being transported on the conveyor belt assembly 1 through the combing device 5, so that the stacking assembly 3 can be stably guided, which is convenient for the subsequent PVC film rolls of the stacking assembly 3 to be quickly and accurately grasped and stacked.

[0021] The present technical solution also includes: a conveyor belt assembly 1, the top surface of which is provided with a 5% slope opposite to its conveying direction, and the width of the conveyor belt assembly 1 is greater than the length of the PVC film roll, and at the same time, a one-way limiter 4 is provided on the conveyor belt of the conveyor belt assembly 1 to limit the rolling of the PVC film roll, and the middle section of the conveyor belt assembly 1 is provided with a comber 5 and a limiter 6 for arranging scattered PVC film rolls; wherein the 5% slope is set, so that when the conveyor belt assembly 1 is conveying the PVC film roll, the PVC film roll will roll under the action of the slope and its own gravity, and its rolling direction is opposite to the conveying direction of the conveyor belt assembly 1, so that the PVC film roll will be pressed onto the one-way limiter 4, and the one-way limiter 4 is used to separate the PVC film rolls.

[0022] On it, since the discharge position for PVC film rolls on the conveyor belt assembly 1 is fixed with a blocking plate 101, the blocking plate 101 is funnel-shaped, which prevents the PVC film rolls from falling when they are placed in batches on the conveyor belt assembly 1 for transportation. At the same time, it is convenient for the PVC film rolls to be placed in batches on the conveyor belt assembly 1, and the batch PVC film rolls can be independently transported in layers and automatically sorted and adjusted in batches.

[0023] Furthermore, since the one-way limiter 4 includes a positioning piece 401 embedded and fixed on the conveyor belt, a damping pressure plate 402 is rotatably installed on the positioning piece 401, and the damping pressure plate 402 is used to limit the position of the PVC film roll, and an elastic member is installed between the damping pressure plate 402 and the positioning piece 401; the contact surface between the damping pressure plate 402 and the PVC film roll is made of damping rubber material, and the direction of the compression deformation of the damping pressure plate 402 during rotation is the same as the 5% slope direction of the conveyor belt, wherein the combined maximum elastic force of the elastic members is balanced with the gravity of a single PVC film roll; in the above-mentioned one-way limiter 4 for separating the PVC film rolls When a single PVC film roll is separated, the elastic member and the damping pressure plate 402 jointly support the PVC film roll, so that the PVC film roll is brought to the position of the comber 5 by the one-way limiter 4 and the conveyor belt assembly 1 for combing. When multiple PVC film rolls press the one-way limiter 4 at the same time, the elastic member is compressed, and the damping pressure plate 402 rotates and compresses, so that the PVC film roll rolls from the compressed one-way limiter 4 due to the 5% slope of the conveyor belt assembly 1 to the initial position of the blocking plate 101, and performs subsequent repetitive independent separation, and then combs at the position of the comber 5.

[0024] Based on the above technical solution, an electromagnet 403 is also fixed on the positioning piece 401, and the electromagnet 403 corresponds to the permanent magnet on the back of the damping pressure plate 402, and the magnetic poles are arranged to repel each other, and when the one-way limiter 4 moves to the vertical projection surface and the left side of the combing device 5, the electromagnet 403 limits the damping pressure plate 402 by repelling the permanent magnet. When the combing device 5 is in the position, the magnetic action of the electromagnet 403 enables the one-way limiter 4 to be unfolded and positioned, thereby achieving the effect of limiting the PVC film roll. Even if the PVC film roll and other external loads apply compressive external force to the one-way limiter 4 at this time, the one-way limiter 4 can remain stable, thereby facilitating the combing device 5 to organize the PVC film roll. Why the PVC film roll needs to be organized, please refer to the following. Figure 10 For example, in order to realize batch conveying and stacking of PVC film rolls, the width of the conveyor belt component 1 needs to be expanded to facilitate the reception and splicing of the PVC film rolls. When the PVC film rolls are not centered, it will also affect the subsequent splicing of the lifting component 2. During the splicing process, the PVC film rolls are prone to get stuck and piled up, so a combing device 5 is set to organize the PVC film rolls.

[0025] In this technical solution, first, a hydraulic component is provided on the carding device 5 to drive the carding frame 501 to move up and down, thereby temporarily intercepting the PVC film roll.

[0026] Secondly, the rotating frame 502 is symmetrically arranged on the combing frame 501 and about its vertical coaxial line. The two rotating frames 502 rotate synchronously and in different directions, and the rotating frame 502 and the elastic airbag 503 are also arranged in a relative rotation structure. A toothed disc 504 is also provided at the bottom of the combing frame 501 and is coaxially distributed with the rotation axis of the rotating frame 502. The outer wall of the toothed disc 504 is meshed with the gear 505 at the top shaft end of the elastic airbag 503. The elastic airbag 503 utilizes the driving position of the rotating frame 502, as well as its own rotation and elastic compression deformation external force to achieve the centering of the PVC film roll, and a raised rubber strip is provided on the outside of the elastic airbag 503, which is weakly adhered to the outer wall of the PVC film roll. The combing frame 501 that subsequently descends drives the rotating frame 502 to rotate or swing through the started motor assembly. The elastic airbag 503 on the rotating frame 502 and the weak viscosity of the rubber strip thereon give the PVC film roll that is not neatly centered a thrust from the end and the center, so that the PVC film roll is centered by external force. During this process, the one-way limiter 4 supports the back of the PVC film roll. At the same time, when the elastic airbag 503 on the rotating frame 502 moves synchronously and external force is applied to the PVC film roll, the toothed disc 504 and the combing frame 501 are synchronously stationary, and the toothed disc 504 and the gear 505 are engaged with each other. When the elastic airbag 503 moves, it also rotates due to the meshing transmission, stably assisting the PVC film roll to be centered.

[0027] Then, the PVC film roll is centered and the PVC film roll that is pushed and moved in the center is limited by the limiter 6 to prevent it from being deflected again due to external force load, wherein the bottom surface of the limiter 6 is in contact with the top surface of the conveyor belt of the conveyor belt assembly 1.

[0028] The limiter 6 is arranged on the left and right sides of the conveyor belt assembly 1, and the limiter 6 includes a positioning plate 601 fixed on the conveyor belt assembly 1, and a movable baffle 602 positioned on the positioning plate 601 by bolts, wherein the movable baffle 602 and the positioning plate 601 are respectively provided with a brush 604 and a ball 603; the spacing between adjacent positioning plates 601 is less than the length of the PVC film roll, wherein the top surface of the positioning plate 601 is used to receive the two ends of the PVC film roll, and the obliquely arranged brush 604 is oriented in the same vertical direction as the conveyor belt assembly 1; In the above scheme, when the PVC film roll is centered, the hydraulic component on the combing device 5 realizes the upward movement and reset of the combing frame 501 and the structure thereon, while the rotating frame 502 is still rotating and swinging. Under the action of external force, the two ends of the PVC film roll can be pushed to the positioning plate 601, and the movable baffle 602 is used to limit the end portions of the PVC film roll to prevent the PVC film roll from moving axially. At the same time, the two ends of the PVC film roll are pushed to the positioning plate 601, and the ball 603 reduces the contact friction between the two ends of the PVC film roll. force, and at the same time, the middle section of the PVC film roll is still blocked by the one-way limiter 4 and driven by the power of the conveyor belt assembly 1, so that the PVC film roll is stably and continuously transported to the lifting assembly 2 and the stacking assembly 3 under the joint action of the limiter 6 and the one-way limiter 4 and the conveyor belt assembly 1 for subsequent stacking, wherein the retaining brush 604 can prevent the end of the PVC film roll from contacting the movable baffle 602 and causing collision and blocking, and at the same time, the retaining brush 604 can also form a damping obstacle for the reverse movement of the PVC film roll, thereby facilitating the transportation of the PVC film roll.

[0029] In the above solution, the movable baffle 602 is positioned by bolts, which facilitates the adjustment of the spacing according to PVC film rolls of different lengths, thereby completing efficient and orderly PVC film roll transportation.

[0030] Example 2: Based on Example 1, the present invention further discloses another rotation driving structure for driving the elastic airbag 503 to move synchronously with the rotating frame 502. The specific contents are as follows: Figure 12 A rotating wheel is fixed at the upper end of the elastic airbag 503, and a torsion rope 506 is wound around the outside of the rotating wheel. At the same time, the other end of the torsion rope 506 is fixed to the combing frame 501, and the elastic airbag 503 is also provided with a torsion spring at the through-rotating connection with the rotating frame 502. Therefore, when the elastic airbag 503 is displaced, due to the action of external force and the action of the torsion spring and the torsion rope 506, the elastic airbag 503 is also rotated and reset during displacement, pushing the PVC film roll to achieve the effect of centering and positioning.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
