Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber production and post-processing, in particular to a glass fiber yarn roll transfer device. Background Art

[0002] The automated packaging production line for glass fiber mainly includes a feeding process, a packaging process, and a glass fiber yarn roll transfer device connecting the two processes; first, the glass fiber yarn roll is transported from the feeding process to the transfer starting point of the glass fiber yarn roll transfer device, and then the glass fiber yarn roll transfer device transfers it to the corresponding transfer end point, that is, the starting point of the packaging position, and then the packaging equipment at this position grabs and packages it; and whether the packaging equipment can accurately grab the glass fiber yarn roll to be packaged will affect the quality and efficiency of subsequent packaging; and to achieve the above-mentioned accurate grabbing, the glass fiber yarn roll needs to be accurately positioned, which requires the cooperation of the transfer device; therefore, the glass fiber yarn roll transfer device is a key equipment connecting various production links, and its performance and efficiency directly affect the operation of the entire production line. The transfer device widely used on the market is a conveyor belt. When working, the glass fiber yarn roll is directly placed on the conveyor belt, and the conveyor belt sends it to the packaging position, but this traditional conveying mode has many shortcomings, mainly the following three points:

[0003] First, product positioning is imprecise. On the one hand, fiberglass products may vary in shape and size, and their outer surfaces are easily damaged, making accurate positioning difficult during transportation. On the other hand, fiberglass products may be affected by vibration, friction, and other factors during transportation, causing the product to shift position when it reaches the baler. Especially when the product first arrives at the baling location, it is easily affected by inertia and cannot stop accurately at the target position, which is not conducive to accurate grasping and packaging by the subsequent baling equipment.

[0004] Second, low efficiency. To reduce the impact of the above-mentioned factors such as vibration and friction, as well as to reduce inertial force and ensure the most accurate positioning of products, the speed of traditional conveyor belts is often slow, which seriously affects the efficiency of the entire production line.

[0005] Third, poor coordination. On automated packaging lines, transfer devices must closely coordinate with the feeding and packaging processes at the front and back ends to achieve a continuous and efficient production process. However, in the traditional conveying mode described above, the offset time and distance must also be taken into account to truly achieve continuous and efficient production. However, the uncertainties of offset time and distance can easily lead to mismatched conveying speeds. This means that traditional conveyor belts often struggle to form a good linkage with the equipment before and after them, leading to production line jams and delays, impacting overall production efficiency.

[0006] In summary, there are many deficiencies in the application of existing conveyor belts in glass fiber automated packaging production lines, and there is an urgent need to develop a new transfer device that can solve the above problems and improve production efficiency. Utility Model Content

[0007] In view of the deficiencies in the prior art, the present invention provides a glass fiber yarn roll transfer device, which solves the problems of inaccurate product positioning, low efficiency and low coordination in the prior art.

[0008] According to an embodiment of the present invention, a glass fiber yarn roll transfer device is provided between the feeding process and the packaging process on an automated glass fiber packaging production line, and comprises:

[0009] A translation precision control assembly, comprising a guide rail arranged between the feeding process and the packaging process and a slider matched with the guide rail, wherein the slider is connected to a reciprocating precision control mechanism for controlling its reciprocating motion;

[0010] The tray is connected to the slider and is provided with a yarn roll placement through hole extending in a vertical direction, and the width of the yarn roll placement through hole is smaller than the diameter of the glass fiber yarn roll.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) Accurate product positioning. The feeding process delivers the glass fiber yarn roll to the pallet located at the starting point of the guide rail transfer, and then starts the round-trip precision control mechanism to make its control slider slide on the guide rail to the transfer end point, thereby driving the pallet and the glass fiber yarn roll on the pallet to slide to the transfer end point. At this time, the packaging equipment at this position grabs the glass fiber yarn roll and performs subsequent packaging operations. After the glass fiber yarn roll is grabbed, the round-trip precision control mechanism controls the empty pallet to return to the transfer starting point, waiting for the next glass fiber yarn roll to be delivered. During this process, since the pallet is provided with a yarn roll placement hole with a width smaller than the diameter of the glass fiber yarn roll, on the one hand, it is convenient to place and position the glass fiber yarn roll on the pallet at the starting point of the transfer; on the other hand, the yarn roll placement hole has a better limiting effect on the glass fiber yarn roll with a certain weight, making it less likely to roll back and forth due to vibration, friction or inertia; therefore, the glass fiber yarn roll can always be well positioned on the pallet, and its position depends entirely on the position of the pallet; and because the pallet is connected to the slider on the guide rail, and the slider slides smoothly along the accurate sliding path on the guide rail under the control of the reciprocating precision control mechanism, as long as the transfer starting point and transfer end point on the guide rail are accurately positioned, the positioning of the pallet can be guaranteed, and ultimately the positioning of the glass fiber yarn roll can be guaranteed accurately.

[0013] (2) The shape and size of the product are relatively flexible. First, for a certain size of yarn roll placement hole, glass fiber yarn rolls within a certain outer diameter range and with a certain deformation can be well accommodated therein; secondly, the size of the yarn roll placement hole can also be customized according to the outer diameter of the glass fiber yarn roll to be processed; therefore, the shape and size of the product are relatively flexible.

[0014] (3) High efficiency. Traditional conveyor belts convey glass fiber yarn rolls at a relatively slow speed to reduce positioning accuracy issues of glass fiber yarn rolls caused by factors such as vibration, friction, and inertia. In the present application, the glass fiber yarn rolls are stably confined within the yarn roll placement through-hole, and the reciprocating precision control mechanism drives the slider to slide stably on the guide rail, thereby enabling the glass fiber yarn rolls to be conveyed at a relatively fast speed.

[0015] (4) High degree of coordination. Similarly, since the position of the glass fiber yarn roll is completely determined by the position of the tray, and the tray is directly connected to the slider on the guide rail, its position can be precisely controlled, and thus the position of the glass fiber yarn roll can also be precisely controlled; therefore, the transfer device of the present application can form a good linkage relationship with the front and rear equipment, and the degree of coordination is high.

DETAILED DESCRIPTION

[0025] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0026] like Figures 1-8 As shown, an embodiment of the utility model proposes a glass fiber yarn roll transferring device, which is arranged between the feeding process and the packaging process on the glass fiber automated packaging production line, and includes a translation precision control component and a tray 500, the translation precision control component includes a guide rail 200 arranged between the feeding process and the packaging process and a slider 300 matched with the guide rail 200, the slider 300 is connected to a reciprocating precision control mechanism for controlling its reciprocating motion; the tray 500 is connected to the slider 300 and is provided with a yarn roll placement through hole 510 extending in a vertical direction, and the width of the yarn roll placement through hole 510 is smaller than the diameter of the glass fiber yarn roll 100.

[0027] Specifically: the glass fiber yarn roll 100 has the following Figure 1 and Figure 2 The cylindrical structure shown in the figure has a winding drum 110 at its center, on which the glass fiber is wound. The diameter of the winding drum 110, i.e., the inner diameter of the glass fiber yarn roll 100, is usually a certain value, while the outer diameter of the glass fiber yarn roll 100, i.e., the outer diameter, can vary within a certain range. Due to reasons such as the winding process, the outer shape of the glass fiber yarn roll 100 can vary slightly. The yarn roll placement hole 510 is preferably in the shape of a rectangular parallelepiped. In this case, the tray 500 is in the shape of a rectangular frame, and the space enclosed by its frame is the yarn roll placement hole 510. In addition, to reduce weight, the thickness of the tray 500 should not be too large. Under this condition, in order to facilitate the bottom end of the glass fiber yarn roll 100 to be placed in the yarn roll placement hole 510 and to ensure that there is a certain amount of accommodation space below the yarn roll placement hole 510, the tray 500 should be placed at an appropriate height. In addition, all components of the device are made of high-quality aluminum alloy materials and precision processing technology, and have high durability and reliability.

[0028] When the present invention is in use: the feeding process transports the glass fiber yarn roll 100 to the tray 500 located at the transfer starting point of the guide rail 200, and then starts the round-trip precision control mechanism to control the slider 300 to slide on the guide rail 200 to the transfer end point, thereby driving the tray 500 and the glass fiber yarn roll 100 on the tray 500 to slide to the transfer end point. At this time, the packaging equipment at this position grabs the glass fiber yarn roll 100 and performs subsequent packaging operations. The specific grabbing can be completed by a robot. After the glass fiber yarn roll 100 is grabbed, the round-trip precision control mechanism controls the empty tray 500 to return to the transfer starting point, waiting for the next glass fiber yarn roll 100 to be delivered.

[0029] In this utility model:

[0030] On the one hand, the product is precisely positioned. During the entire transfer process, since the tray 500 has a yarn placement hole 510 with a width smaller than the diameter of the glass fiber yarn roll 100, on the one hand, it is convenient to place and position the glass fiber yarn roll 100 on the tray 500 at the transfer starting point; on the other hand, the yarn placement hole 510 has a good limiting effect on the glass fiber yarn roll 100 with a certain weight, making it less likely to roll back and forth due to vibration, friction or inertia; therefore, the glass fiber yarn roll 100 can always be well positioned on the tray 500, and its position is completely determined by the position of the tray 500; and because the tray 500 is connected to the slider 300 on the guide rail 200, and the slider 300 slides smoothly along the accurate sliding path on the guide rail 200 under the control of the reciprocating precision control mechanism, as long as the transfer starting point and transfer end point on the guide rail 200 are accurately positioned, the positioning of the tray 500 can be guaranteed, and thus the positioning of the glass fiber yarn roll 100 can be ultimately guaranteed.

[0031] On the other hand, the product shape and size are relatively flexible. First, for a yarn roll placement hole 510 of a certain size, glass fiber yarn rolls 100 within a certain outer diameter range and with a certain deformation can be well accommodated therein; secondly, the size of the yarn roll placement hole 510 can also be customized according to the outer diameter of the glass fiber yarn roll 100 to be processed; thus, the product shape and size are relatively flexible.

[0032] On the other hand, the efficiency is high. Traditional conveyor belts convey the glass fiber yarn roll 100 at a relatively slow speed to reduce positioning accuracy issues of the glass fiber yarn roll 100 caused by factors such as vibration, friction, and inertia. However, in the present application, the glass fiber yarn roll 100 is stably confined within the yarn roll placement through-hole 510, and the reciprocating precision control mechanism drives the slider 300 to slide stably on the guide rail 200, thereby being able to convey the glass fiber yarn roll 100 at a relatively fast speed.

[0033] Finally, the degree of coordination is high. Similarly, since the position of the glass fiber yarn roll 100 is completely dependent on the position of the tray 500, and the tray 500 is directly connected to the slider 300 on the guide rail 200, its position can be precisely controlled, and thus the position of the glass fiber yarn roll 100 can also be precisely controlled; therefore, the transfer device of the present application can form a good linkage relationship with the front and rear equipment, and the degree of coordination is high.

[0034] Further, such as Figure 5-Figure 8 As shown, in order to protect the outer ring quality of the glass fiber yarn roll 100, the inner wall of the yarn roll placement hole 510 and the contact point with the glass fiber yarn roll 100 are in a smooth arc shape. Specifically, the upper half of the inner wall of the yarn roll placement hole 510 along its width direction is designed to be an arc shape that matches the size of the glass fiber yarn roll 100, and even the entire inner wall is designed to be an arc shape, so that the bearing part of the yarn roll placement hole 510 is changed from a sharp right angle to a smooth arc, thereby effectively preventing the glass fiber yarn roll 100 from being cut or crushed. In addition, other design methods of the bearing part, such as chamfering or rounding the sharp right angles of the bearing part, can effectively protect the glass fiber yarn roll 100.

[0035] Further, if Figure 5 As shown, for better positioning, stoppers 520 are protruding from the top of the tray 500 in both rolling directions when the glass fiber yarn roll 100 is placed on the yarn roll placement through hole 510.

[0036] Furthermore, if Figure 1-Figure 2 As shown, to enhance structural stability and sliding stability, there are two guide rails 200, which are arranged in parallel. There are four sliders 300, which are symmetrically distributed on the two guide rails 200 and each slider 300 is fixedly connected to the tray 500. In addition, limit blocks 210 are provided at both ends of the guide rails 200 along their length to prevent the sliders 300 from slipping.

[0037] like Figure 1-Figure 2As shown, according to another embodiment of the present invention, the reciprocating precision control mechanism includes a linear slide module 410 and a connecting assembly. The linear slide module 410 includes a linear slide 411, a slide plate 412 and a servo motor 413. The linear slide 411 is arranged in parallel on one side of the guide rail 200. The slide plate 412 is slidably connected to the linear slide 411. The output shaft of the servo motor 413 is fixedly connected to a screw rod, and the screw rod is threadedly connected to the slide plate 412. The linear slide module 410 of the present application is preferably a track-embedded slide module, and its screw rod and the part of the slide plate 412 with a threaded through hole that matches the screw rod are embedded in the interior of the linear slide 411 to achieve a more compact structural design and higher system rigidity. The connecting assembly is connected to both the skateboard 412 and the tray 500. Specifically, the connecting assembly includes a connecting plate 421 and a connecting rod 422. The connecting plate 421 is fixedly connected to the skateboard 412. Specifically, the connecting plate 421 is fixedly connected to the top of the skateboard 412 and the contact area between the two is as large as possible to ensure the stability of the connection. One end of the connecting rod 422 is connected to the connecting plate 421 and the other end is connected to the tray 500. Specifically, the top of the connecting rod 422 is connected to the bottom of the connecting plate 421, and the bottom of the connecting rod 422 is connected to the top of the tray 500 to maximize space saving.

[0038] During use of this embodiment, after the servo motor 413 is activated, its output shaft rotates, driving the screw to rotate, which in turn drives the slide plate 412 to slide linearly along the length of the linear slide 411. The slide plate 412, in turn, drives the slider 300 to slide linearly along the length of the guide rail 200 via the connecting plate 421, the connecting rod 422, and the tray 500, thereby causing the tray 500 to slide linearly along the length of the guide rail 200. In this embodiment, by arranging the linear slide module 410 parallel to one side of the guide rail 200 to drive the slider 300 to slide, this not only fully utilizes the space on one side of the guide rail 200, but also makes assembly more flexible.

[0039] Further, such as Figure 1-Figure 2 As shown, the glass fiber yarn roll transferring device also includes a base plate 700 and a start-up position photoelectric sensor 610; the upper end of the base plate 700 is connected to the guide rail 200, specifically, the top of the base plate 700 is provided with a finishing guide rail positioning groove arranged along the direction of the guide rail 200, and the bottom end of the guide rail 200 extends into the finishing guide rail positioning groove and is connected; the base plate 700 is provided with a plurality of weight-reducing through holes 710 extending in the vertical direction; the linear slide 411 is installed on the base plate 700 and is located on one side of the guide rail 200; the start-up position photoelectric sensor 610 is arranged on the base plate 700 and is connected to the servo motor 413, and it is generally connected to the servo motor 413 through a control system. The control system is a prior art and will not be repeated here; in addition, the start-up position photoelectric sensor 610 is located on the starting end side of the sliding path of the tray 500.

[0040] Specifically, the base plate 700 serves as the foundational support for the entire device, supporting all other components. It is constructed from lightweight, high-strength aluminum alloy or composite materials to reduce overall weight. The base plate 700 is designed as a hollow structure. In the case of two guide rails 200, the weight-reducing through-holes 710 are preferably spaced between the two guide rails 200 to achieve a weight-reducing design while ensuring rigidity and stability. Furthermore, two precision-machined guide rail positioning grooves are preferably provided, fabricated using high-precision machine tools to ensure parallelism and smooth movement of the guide rails 200. The selection of the start-up position photoelectric sensor 610 is relatively flexible, and is preferably a beam-type or retro-reflective photoelectric sensor with a transmitter and a receiver arranged separately, wherein the transmitter and the receiver are respectively arranged at the two ends of the transfer starting point of the guide rail 200 and are symmetrical; specifically, the height of the transmitter and the receiver are preferably the same as the center height of the glass fiber yarn roll 100, and the connecting line of the transmitter and the receiver has an intersection with the glass fiber part of the glass fiber yarn roll 100, and the intersection is preferably close to the winding drum 110. This arrangement can adapt to glass fiber yarn rolls 100 with more outer diameters when the size of the winding drum 110 is fixed; when in use, when the feeding process accurately puts the glass fiber yarn roll 100 into the yarn roll placement through hole 510 position of the tray 500 located at the transfer starting point, the start-up position photoelectric sensor 610 detects the existence of the glass fiber yarn roll 100 and sends a signal to the control system, indicating that the transfer operation can be performed. After the control system receives the signal that the glass fiber yarn roll 100 has been placed in place, it starts the servo motor 413.

[0041] like Figures 1-4 As shown, according to another embodiment of the present utility model, the linear slide module 410 also includes a limit position slot type sensor 630 and a zero position slot type sensor 620, and there are two limit position slot type sensors 630, and the two limit position slot type sensors 630 are respectively arranged on the linear slide 411 at both ends along the length direction of one side of the slide 412; the zero position slot type sensor 620 is arranged on the linear slide 411 between the two limit position slot type sensors 630; when the signal blocking plate 650 connected to the slide 412 slides with the slide 412 and penetrates into the sensing slot 640 of any one of the two limit position slot type sensors 630 and the zero position slot type sensor 620, the servo motor 413 stops running.

[0042] Specifically: the slot sensor is a type of photoelectric sensor, whose transmitter and receiver are integrated into one body, and the two parts are respectively on both sides of the sensing slot 640 of the slot sensor. Such a structure determines that whenever the object to be detected passes through the sensing slot 640 and blocks the light signal, the switch detection function of the slot sensor will be triggered; the signal blocking piece 650 is the object to be detected, and whenever the signal blocking piece 650 passes through the sensing slot 640 of the slot sensor, it can block the light, thereby prompting the slot sensor to complete the effective control of the signal; compared with other traditional photoelectric sensors, the safety performance of the slot sensor is more reliable, and it is more suitable for signal detection work under high-speed conditions; the zero-position slot sensor 620 and the two-limit position slot sensors 630 all belong to the slot sensors and the three are installed on the same side of the linear slide 411. Preferably, the zero-position slot sensor 620 is close to the limit position slot sensor 630 near the transfer end point, which is better. Optionally, when the slide 412 is at its sliding starting point (corresponding to the position of the transfer starting point), the signal blocking plate 650 is just outside the sensing slot 640 of the limit position slot sensor 630 near the transfer starting point; when the slide 412 slides to the point where the tray 500 is at the transfer end point, the signal blocking plate 650 is then inserted into the sensing slot 640 of the zero position slot sensor 620, and the light signal in the sensing slot 640 of the zero position slot sensor 620 is blocked and a zero position signal (i.e., origin signal) is emitted; when the control system detects the zero position signal, the servo motor 413 immediately decelerates and stops, thereby completing the origin return operation, so that the tray 500 stops accurately at the transfer end point; when the tray 500 needs to return to the transfer starting point from the transfer end point, the servo motor 413 controls the slide 412 to move a preset distance from the origin and reach the sliding starting point, thereby driving the tray 500 to accurately return to the transfer starting point, waiting for the placement of the next glass fiber yarn roll 100.

[0043] In this embodiment, the slot width of the slot sensor is the detection distance of the product, and in this application, a slot sensor with a slot width of about 5 mm is preferred, which is very compact and can be integrated into the linear slide module 410; and the slot sensor supports signal detection in high-speed state, further ensuring the transfer efficiency; and because the slot sensor is very sensitive, the servo motor 413 can be stopped quickly, at this time, on the one hand, the position accuracy of the origin and the transfer end point is guaranteed, and on the other hand, it further reflects that the limiting effect of the yarn roll placement through hole 510 in the tray 500 is very good, and the glass fiber yarn roll 100 will not be shifted in the fast stop state; in addition, the setting of the zero position slot sensor 620 ensures the accuracy of the transfer starting point and transfer end point of the tray 500; finally, the two limit position slot sensors 630 prevent the slide 412 from slipping, thereby increasing the safety of the device. Finally, preferably, this embodiment is a further optimization based on the aforementioned embodiments.

[0044] When using:

[0045] Initial state ( Figure 1-Figure 3 ): The device is in standby mode, the tray 500 is at the initial position of the transfer starting point, and the glass fiber yarn roll 100 has not yet been placed on the yarn roll placement hole 510. The infrared light emitted by the transmitter of the power-on position photoelectric sensor 610 (taking the infrared light-emitting photoelectric sensor as an example, the same below) is completely received by its receiver and will not trigger its output to start the servo motor 413 to run; the signal blocking plate 650 is just outside the sensing slot 640 of the corresponding limit position slot sensor 630, and it is not inserted into the sensing slot 640 of any of the two limit position slot sensors 630 and the zero position slot sensor 620. The infrared light (taking infrared light as an example) emitted by the transmitter at one end of each of the sensing slots 640 can be completely received by the receiver at the other end, and will not trigger the output of a signal to shut down the servo motor 413; accordingly, the slide 412 is also at its sliding starting point.

[0046] Placement of the glass fiber yarn roll 100: The glass fiber yarn roll 100 delivered from the feeding process is put into the equipment, and after being grabbed by a robot, it is accurately placed in the yarn roll placement hole 510; at this time, the infrared light emitted by the transmitter of the power-on position photoelectric sensor 610 is blocked by the glass fiber yarn roll 100, and its receiver cannot receive the complete light signal, thereby triggering it to output a signal to the control system to start the servo motor 413.

[0047] Transfer start: After the control system receives the signal for starting the servo motor 413 from the start-up position photoelectric sensor 610, it starts the servo motor 413, and at the same time the control system starts to detect the zero position signal (i.e., the origin signal); the output shaft of the servo motor 413 rotates, driving the screw to rotate, and then driving the slide plate 412 to slide in a straight line along the length direction of the linear slide 411, and the slide plate 412 drives the slider 300 to slide in a straight line along the length direction of the guide rail 200 through the connecting plate 421, the connecting rod 422 and the tray 500, so that the tray 500 and the glass fiber yarn roll 100 also slide in a straight line along the guide rail 200 toward the transfer end point; at this time, correspondingly, the signal blocking plate 650 moves away from the limit position slot sensor 630 near the transfer starting point, and starts to run toward the zero position slot sensor 620.

[0048] Transfer into place: When the slide 412 moves to the signal blocking piece 650 and inserts into the sensing slot 640 of the zero position slot sensor 620, the infrared light emitted by the transmitter at one end of the sensing slot 640 of the zero position slot sensor 620 is blocked, so that the receiver at the other end cannot receive the complete light signal, thereby triggering the zero position slot sensor 620 to send a zero position signal. After the control system detects the zero position signal, it controls the servo motor 413 to decelerate and stop running immediately. The output shaft of the servo motor 413 stops rotating, and the lead screw also stops rotating, thereby causing the slide 412 to stop running, and then the slider 300 and the tray 500 both stop running. At this time, the position of the tray 500 is the end point of the transfer, and it is also the starting point of the packaging process; after the tray 500 stops, the glass fiber yarn roll 100 on it stops steadily at the target position due to the limiting effect of the yarn roll placement through hole 510, and the transfer operation is completed.

[0049] Subsequent processing: After being transferred into place, the grabbing equipment of the packaging process, such as another robot, immediately processes or transports the glass fiber yarn roll 100; the rear servo motor 413 controls the slide plate 412 to return from the origin to the sliding starting point, and the empty pallet 500 also returns to the initial position of the transfer starting point, ready for the next round of operations.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
