Description

Technical Field

[0001] This invention relates to a conveyor table device, and more specifically, to a fabric roll conveyor table. Background Technology

[0002] Fabric rolls used in enterprise production are usually large in volume and weight, and handling them requires a lot of manpower. Fabric rolls are usually transported by fabric roll conveying devices. Existing fabric roll conveying devices usually rely on their own length to achieve the transportation distance. This means that the length or volume of the conveying device also needs to be set according to the transportation distance, which limits the practicality of the fabric roll conveying table.

[0003] For example, Chinese Patent Publication No. CN111908227A, published on November 10, 2020, entitled "An Intermittent Fabric Conveying Device," discloses a fabric transport device including a conveying platform and a conveying cavity within the platform. Multiple parallel movable grooves are provided along the length of the bottom surface of the conveying platform, and a conveying strip is movably placed in each groove. The conveying strip is movably mounted on the conveying plate. This design can ensure the stability of the fabric during transport. However, the conveying distance of this device is limited by its own length; to increase the conveying distance, the device's length must be increased, making its use easily limited. Summary of the Invention

[0004] This invention overcomes the problem that the conveying distance of existing fabric conveying devices is affected by their own length, and provides a fabric conveying platform. In this solution, the conveying distance of the fabric conveying platform can reach at least twice its own length, which greatly improves the practicality of the fabric conveying platform.

[0005] To address the aforementioned shortcomings, this invention employs the following technical solution: a fabric roll conveyor, comprising a base and a conveying platform. The conveying platform is slidably connected to the base, and its two extreme positions can slide to the extreme positions of the base. The base is equipped with a driving device for driving the conveying platform to slide on the base. The driving device allows the conveying platform to slide on the base, and the left extreme position of the conveying platform can slide to the right extreme position of the base, and the right extreme position of the conveying platform can slide to the left extreme position of the base. Therefore, the distance that the fabric roll can be transported is twice the length of the conveying platform plus the length of the base. That is, the conveying distance of the fabric roll conveyor is at least twice its own length, greatly improving the transport distance of the fabric roll conveyor. This solution not only allows for normal use but also enables long-distance transport in long and narrow spaces without increasing the volume of the conveying equipment.

[0006] Preferably, the conveying platform is provided with a plurality of transmission blocks along its sliding direction, and a transmission block is provided at each of the extreme positions at both ends of the conveying platform. The driving device includes a transmission bar that engages with at least one transmission block at any given time. A transmission block is provided at each of the extreme positions at both ends of the conveying platform to ensure that the conveying platform does not disengage when sliding to its extreme position. The driving device is provided with a transmission bar that engages with the transmission blocks. The driving device drives the transmission bar, thereby moving the transmission blocks and causing the conveying platform to slide. Specifically, the transmission bar must engage with at least one transmission block on the conveying platform at any given time to prevent the conveying platform from disengaging and becoming immobile, or even causing the conveying platform to detach from the base and resulting in a safety accident.

[0007] Preferably, the transmission block is fixed to the conveying platform. To ensure that the conveying platform can be driven by the transmission bar, the transmission block needs to be fixed to the conveying platform. When the transmission block engages with the transmission bar, it can drive the conveying platform to slide.

[0008] Preferably, the transmission block is rotatably connected to the conveying platform, and the transmission block has a circumferential arc hole, within which a stop block fixed to the conveying platform is installed. To reduce the impact stress when the transmission bar and transmission block are just engaged, the transmission block is rotatably connected to the conveying platform. When the transmission bar and transmission block are engaged, the transmission block rotates slightly. Only when the arc hole on the rotating block contacts the stop block can it restrict the rotation of the transmission block, thereby driving the conveying platform to move. This provides a buffer time when the transmission block and transmission bar first contact, thus reducing the impact stress at that moment. Simultaneously, since the outer circle of the transmission block contacts the transmission bar, and the arc hole is inside the transmission block, the linear velocity at the location of the arc hole is less than the linear velocity of the outer circle of the transmission block, achieving a speed-reducing impact effect. This transforms the originally high-speed impact into a low-speed impact, effectively preventing violent impacts between the transmission block and transmission bar, and increasing the service life of both. Damping can also be added between the arc hole and the stop block to further improve the buffering effect.

[0009] Preferably, the conveying platform is provided with a transmission bar along its sliding direction, and the driving device includes a transmission block that is engaged with the transmission bar at all times. This solution sets the transmission block on the driving device and the transmission bar on the conveying platform, still achieving the effect of the conveying platform sliding on the base while having at least twice the conveying distance. Furthermore, the transmission block must be engaged with the transmission bar at all times to prevent the conveying platform from disengaging.

[0010] Preferably, a sliding mechanism is provided at the sliding connection between the base and the conveying platform. The sliding mechanism includes a slide rail fixed to the base and a guide block fixed to the conveying platform. The sliding mechanism is used for the conveying platform to slide on the base. The sliding mechanism includes a slide rail and a guide block, the guide block slides within the slide rail, and also has a guiding function to ensure the normal movement of the conveying platform.

[0011] Preferably, one of the slide rail and guide block is provided with several sets of vertically distributed guide wheels, and the other is provided with a guide plate that slides in conjunction with the guide wheels. The slide rail and guide block move through the rolling motion between the guide wheels and the guide plate, and the rolling transmission effectively reduces friction.

[0012] Preferably, the sliding mechanism is connected to a guide plate via a rotating frame. The rotating frame includes rotating rods of varying lengths, with the lengths gradually decreasing along the guide direction. The guide plate is used primarily for transporting the rolled fabric. The rotating rods can rotate to a position horizontal to the conveyor platform or perpendicular to it. When the rotating rods are perpendicular to the conveyor platform, the guide plate can be mounted on the rotating rods, and the rotating rods can be fixed to prevent changes in the guide plate's position. When the rotating rods are rotated to a horizontal position, the guide plate can be disassembled and the rotating rods stored away. The decreasing length of the rotating rods along the guide direction allows the guide plate to be installed in an inclined state, enabling the fabric to be transported under its own weight.

[0013] Preferably, a baffle plate is rotatably connected to the middle of the conveying platform. When the baffle plate is rotated to a horizontal position, it coincides with the conveying platform; when rotated to a vertical position, its height is higher than that of the guide plate. The baffle plate is rotatably connected to the conveying platform and is mainly used to block the rolled fabric, preventing it from rolling off the baffle plate. This method is applicable to situations requiring intermittent conveying of rolled fabric. When the baffle plate is rotated to a vertical position, it is also necessary to ensure that the height of the rolled fabric on the guide plate is less than the maximum height of the baffle plate to achieve the desired baffle effect.

[0014] Preferably, the conveyor platform is also equipped with a conveyor belt, which is level with the conveyor platform. The conveyor belt can serve as another method for conveying rolled fabric on the conveyor platform. When a guide plate is not required, the conveyor platform can be used to convey the rolled fabric, increasing the practicality of the conveyor platform.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) the transport distance of the roll cloth is longer, at least twice that of the conveying platform; (2) the operation of intermittent conveying of the roll cloth can be realized; (3) the transmission structure has the effect of reducing impact stress and can improve the service life of the transmission structure; (4) the transport accuracy is high and the roll cloth can be accurately transported to any position; (5) compared with long-distance transport equipment, the volume is smaller and the floor space is saved; (6) it has two transport modes, which makes it more applicable and more practical.

[0025] The technical solutions of the present invention will be further specifically described below through specific embodiments and in combination with the drawings.

[0026] Embodiment 1: As Figures 1 to 6A cloth winding and conveying table as shown includes a conveying platform 2 and a base 1. The conveying platform 2 is slidably connected to the base 1 through a sliding mechanism 8. Rotating frames 13 are provided on both sides of the conveying platform 2. The rotating frame 13 includes two groups of rotating rod frames 15, and the length of the rotating rod frame 15 gradually decreases along the conveying direction of the cloth roll 27. The cloth guiding plate 14 is fixed on the rotating rod frame 15 through cloth guiding screws 18 and is arranged obliquely to prevent the cloth roll 27 from vibrating when it falls on the cloth guiding plate 14, shaking the cloth guiding plate 14 out of the rotating rod frame 15 and dropping, damaging the cloth guiding plate 14. When the cloth roll 27 is transported onto the cloth guiding plate 14, the cloth roll 27 can roll under its own gravity and be transported to the next working station. Among them, the number of cloth guiding plates 14 is two, and they are respectively arranged on both sides of the conveying platform 2, so that the cloth roll 27 can be supported at both ends and is more stable during the conveying process and not prone to instability. A cloth blocking plate 16 is further provided on the conveying platform 2 between the two cloth guiding plates 14. The cloth blocking plate 16 is rotatably connected to the conveying platform 2 and is driven by a cylinder 26, so that the cloth blocking plate 16 can rotate around the surface of the conveying platform 2. When the cloth blocking plate 16 rotates to the horizontal position, the cloth blocking plate 16 is flush with the conveying platform 2. When the cloth blocking plate 16 rotates to the vertical direction, the highest point of its vertical position is higher than the height where the cloth guiding plate 14 is located, and it can block the cloth roll 27 from rolling.

[0027] The sliding mechanism 8 includes a guide block 10 and a slide rail 9. A guide plate 12 is provided on the guide block 10. Guide wheels 11 are arranged vertically in the two tracks of the slide rail 9. The guide wheels 11 are fixed to the inner side wall of the slide rail 9 by guide wheel screws 23 and can rotate freely about a fixed axis. The vertically arranged guide wheels 11 can engage with the guide plate 12, and the transmission generated by the guide plate 12 on the guide wheels 11 is rolling, which can greatly reduce the resistance inside the sliding mechanism 8. First left limit blocks 19 and first right limit blocks 20 are respectively provided on both sides of the guide block 10. The first left limit blocks 19 and the first right limit blocks 20 are both close to the end positions of the guide block 10 and are arranged on non - same ends of the guide block 10. Second right limit blocks 21 and second left limit blocks 22 are respectively provided on the two inner side walls of the slide rail 9 corresponding to the first left limit blocks 19 and the first right limit blocks 20. When the guide block 10 moves in the slide rail 9, when the guide block 10 moves to the limit position, the first left limit block 19 and the second right limit block 21 can be in contact or the first right limit block 20 and the second left limit block 22 can be in contact, which can prevent the guide block 10 from slipping out of the slide rail 9 and causing safety accidents. Moreover, the vertical arrangement of the guide wheels 11 can reduce the vibration during the movement of the guide block 10, making the cloth roll 27 transported more smoothly. In addition to the above settings, the guide plate 10 and the guide wheels 11 can also be implemented in the following way: the guide plate 12 is arranged on the two inner side walls of the slide rail 9, and the guide wheels 11 are arranged on both sides of the guide block 10 and engage with the guide plate 12, and this scheme can also achieve the above - mentioned movement effect. The sliding mechanism 8 is fixed on the base 1, and the top of the guide block 10 is fixedly connected to the conveying platform 2. The relative sliding between the guide block 10 and the slide rail 9 can be converted into the relative sliding between the base 1 and the conveying platform 2. A number of rolling bearings 31 are also provided on the two side walls of the slide rail 9 at the positions corresponding to the guide plate 12, which can further reduce the sliding resistance of the guide plate 12 inside the slide rail 9 and make the sliding of the guide plate 12 smoother.

[0028] On both sides of the conveying platform 2, there are respectively three driving blocks 4. The driving blocks 4 are in the structure of notched gears and are respectively located at the left and right extreme positions and the middle position of the conveying platform 2. Inside the driving block 4, there is a main fixing hole 24 and two auxiliary holes 25, and the driving block 4 is fixed to the conveying platform 2 by screws. The two auxiliary holes 25 can effectively prevent the driving block 4 from loosening during transmission and prevent the driving block 4 from falling off. There is also a driving device 3 on the base 1. The driving device 3 includes two driving motors 32 and two rotating bars 5. And on both sides of the conveying platform 2, there is respectively a driving motor 32 and a transmission bar 5. In the figure, the rotating bar 5 is in the structure of a transmission chain, and the transmission bar 5 is arranged along the entire length of the conveying platform 2. The teeth on the driving block 4 can be engaged in the chain openings of the transmission chain; since the driving block 4 is fixed on the conveying platform 2 and cannot rotate, when the driving block 4 is engaged with the transmission bar 5, the movement of the transmission bar 5 will drive the driving block 4 to move horizontally, and then drive the conveying platform 2 to move horizontally. Among them, the driving block 4 adopts the structure of a notched gear, and the notch direction is away from the position where the driving block 4 is engaged with the transmission bar 5. On the one hand, it ensures that there are teeth that can be engaged with the transmission bar 5, and on the other hand, it can avoid the notch interfering with the movement of the conveying platform 2.

[0029] The specific movement process is as follows: As Figure 2As shown in the figure, when the conveying platform 2 moves to the left, the driving motor 32 rotates counterclockwise, the transmission bar 5 moves to the left, and the left transmission block on the conveying platform 2 disengages from the transmission bar 5. However, the middle and right transmission blocks still engage with the transmission bar 5 and continue to drive the conveying platform 2 to move to the left. As the conveying platform 2 moves, the middle transmission block also disengages from the transmission bar 5, but the right transmission block still engages with the transmission bar 5 and continues to drive the conveying platform 2 to move to the left. When the right transmission block is about to disengage from the transmission bar 5, the driving motor 32 stops rotating, and at this time, the conveying platform 2 stops moving to the left. If the driving motor 32 fails to stop rotating, the conveying platform 2 will continue to move to the left. Similarly, before the right transmission block disengages from the transmission bar 5, the first right limit stop 20 and the second left limit stop 22 will first come into contact, thereby preventing the conveying platform 2 from moving to the left and preventing safety accidents.至此,为输送平台2向左运动全过程;以上述结束状态为输送平台2向右运动的初始状态,其向右运动的具体过程如下:驱动电机32向右转动,带动传动条5向右运动,进而带动右边的传动块向右运动,输送平台2开始向右运动,随着输送平台2向右运动,中间的传动块和左边的传动块依次与传动条5卡合,输送平台2继续向右运动,右边的传动块和中间的传动块依次脱离传动条5,在左边的传动块脱离传动条5之前,驱动电机32停止转动,输送平台2停止向右运动,如果驱动电机32出现故障没有停止转动,则在左边의传动块将要脱离传动条5之前,第一左极限挡块19和第二右极限挡块21会先抵触,从而阻止输送平台2继续向右运动。由此,输送平台2的双向运动完成。

[0030] During the movement of the conveying platform 2, the conveying distance of the rolled fabric 27 by the conveying platform 2 is: the sum of the lengths of the two conveying platforms 2 plus the length of the base 1 or the length of the slide rail 9. Therefore, this solution can achieve a longer conveying distance of the rolled fabric 27 without increasing the volume of the transportation equipment, and has higher practical value.

[0031] Two conveyor belts 17 are also provided on the conveying platform 2. The conveyor belts 17 are respectively located adjacent to the sliding mechanism 8 and inside the sliding mechanism 8. When it is not necessary to use the fabric guiding plate 114 to convey the rolled fabric 27, the conveyor belts 17 can be used to convey the rolled fabric 27 instead. First, remove the fabric guiding screw 18 that fixes the fabric guiding plate 14, remove the fabric guiding plate 14, then rotate the rotating rod holder 15 to the horizontal position, and finally control the cylinder 26 to contract, pull down the fabric blocking plate 16 until it reaches the horizontal position and coincides with the conveying platform 2. At this time, the rolled fabric conveying platform can adopt the transportation method of the conveyor belts 17, and the transportation of the conveyor belts 17 is in the horizontal direction.

[0032] As Figure 6As shown in the figure, there are also three proximity switches 28 provided on the base 1. The three proximity switches 28 are respectively located at the left and right extreme positions and the middle position of the base 1. Corresponding to the bottom of the conveying platform 2, proximity switch responders 29 corresponding to the three proximity switches 28 are respectively provided. When the proximity switches 28 and the proximity switch responders 29 are in place, they can respectively transmit signals to the driving device 3 to control the driving operation of the driving device 3. In order to be able to detect the position of the rolled fabric 27 on the fabric guide plate 14 or the conveyor belt 17, a photoelectric switch 30 is also provided on the conveying platform 2. This solution can make the conveying distance of the conveying platform 2 more accurate, and can also control the conveying platform 2 to move to any position within its stroke. The driving motor 32 can also rotate forward and reverse at any time, further improving the practicability of the rolled fabric conveying table.

[0033] Embodiment 2: As Figure 7 shown in a rolled fabric conveying table, the difference between it and Embodiment 1 is only that the transmission bar 5 is arranged on the conveying platform 2, and the transmission bar 5 is a straight rack structure. The transmission block 4 is arranged on the driving device 3. The driving device 3 includes three driving motors 32, and respectively controls the rotation of the three transmission blocks 4. At this time, the transmission blocks 4 are all gear structures, and the horizontal movement of the conveying platform 2 is realized through the meshing transmission between the gears and the straight rack.

[0034] The effect of this embodiment is the same as that of Embodiment 1. At any time, it can always be ensured that at least one transmission block 4 is engaged with the transmission bar 5, and at the same time, it can also be ensured that the transportation distance of the conveying platform 2 is at least twice its own length.

[0035] Embodiment 3: As Figure 8 shown in a rolled fabric conveying table, the difference between it and Embodiment 1 is only that the transmission block 4 is rotatably connected to the conveying platform 2, and the auxiliary hole 25 inside the transmission block 4 is replaced with an arc hole 6, and a stop block 7 is provided in the arc hole 6. The technical effect of this embodiment is to increase the effect of reducing the impact stress of the transmission structure on the basis of Embodiment 1.

[0036] In Embodiment 1, since the transmission block 4 is in a fixed state, a large impact stress will be generated between the two when it is engaged with the transmission bar 5. During long-term use, the structure of the transmission block 4 or the transmission bar 5 is likely to be damaged.

[0037] In this embodiment, by changing the transmission block 4, the transmission block 4 is set to be rotatably connected to the conveying platform 2. When the chain opening of the transmission bar 5 is engaged with the teeth of the transmission block 4, it will not immediately cause an impact effect. Instead, the transmission block 4 will first rotate until the arc hole 6 on the transmission block 4 contacts the stop block 7, and when the transmission block 4 stops rotating, the transmission block 4 will be fixed relative to the conveying platform 2, and at this time the conveying platform 2 will start to move horizontally.

[0038] Among them, since the engagement position of the transmission block 4 and the transmission strip 5 is on the outer circle of the transmission block 5, and the arc hole 6 is inside the transmission block 4, when the transmission block 4 rotates, the linear velocity at the arc hole 6 is less than the linear velocity at the engagement position with the transmission strip 5. Therefore, the impact between the arc hole 6 and the stop block 7 is transformed into an impact with a smaller linear velocity, thereby reducing the impact stress. To further reduce the impact stress between the two, a damping can also be provided between the arc hole 6 and the stop block 7; after the damping is provided, it can also reduce the extrusion stress between the transmission block 4 and the transmission strip 5 when the transmission block 4 is relatively fixed.
