Description

Technical Field

[0001] The invention belongs to the technical field of feeding equipment, and in particular relates to a feeding device for large rolls of double-sided tape, transparent tape, easy-tear tape, foam tape and the like. Background Art

[0002] Based on the convenience of carton transportation and the humanization of use, the demand for double-sided tape, easy-tear tape and other tapes for carton boxes is becoming more and more common.

[0003] In the prior art, the automated equipment that sticks these tapes to the paper boxes is called a taping head. The taping head is equipped with a loading mechanism, but the specifications and dimensions of the material roll are basically fixed, the inner core is 3 inches, the maximum outer diameter of the film roll is generally within 400mm (even if it is heightened, the maximum can only be within 500mm), and the width of the material roll is within 100mm. This structure will have major disadvantages when there are large-scale production tasks. Specifically, the production staff must always pay attention to whether the material roll is running out. If it is running out, they must stop the machine and replace the material roll. Sometimes they even need to re-test and debug, which seriously affects production efficiency.

[0004] In view of this, the present invention aims to provide a feeding device, which is mainly for large rolls of double-sided tape, transparent tape, easy-tear tape, foam tape, etc. After the transportation of the present invention, it can directly skip the loading mechanism of the head and enter the swing arm mechanism of the head or directly enter the actuator. Moreover, the present invention can automatically detect whether the material roll is about to run out. The material roll can be replaced conveniently and quickly without re-debugging, and the efficiency is high. Summary of the invention

[0005] The purpose of the present invention is to provide a feeding device to address the shortcomings of the prior art of frequent material roll replacement in the pasting head. The feeding device is mainly used for large rolls of double-sided tape, transparent tape, easy-tear tape, foam tape, etc. After the transportation of the present invention, the loading mechanism of the pasting head can be directly skipped and the swing arm mechanism of the pasting head or the actuator can be directly entered. In addition, the present invention can automatically detect whether the material roll is about to run out. The material roll can be replaced conveniently and quickly without re-debugging, and the efficiency is high.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] A feeding device includes a frame, a driving source, a driving shaft arranged on the frame, a material roll, a material seat, a fixing rod and a swinging rod. The material roll is loaded on the material seat. The driving source drives the driving shaft to rotate, and during operation, the material roll meshes with the driving shaft. The material shaft of the material seat is installed on a material shaft mounting seat, and a bearing seat is arranged on the material shaft mounting seat. The material shaft mounting seat is arranged on a guiding seat, and a first sensor is arranged at the lower end of the guiding seat. The material tape on the material roll is sent to the next process after passing through the fixing rod and the swinging rod.

[0008] Compared with the prior art, in the present invention, by arranging a first sensor at the lower end of the guiding seat, and during operation, the material roll and the driving shaft always maintain a meshing state. During the conveying process of the material roll, the material shaft mounting seat for installing the material shaft moves downward along the guiding seat until the first sensor senses the material shaft mounting seat, indicating that the material roll is almost used up. The first sensor feeds back a warning signal (or a signal to stop the production line), prompting to prepare for replacing the large roll of material. In this way, it is not necessary for production personnel to always pay attention to whether the material roll is almost used up, which reduces the pressure on production personnel and reduces the occurrence of production accidents.

[0009] As an improvement of the feeding device of the present invention, the material seat is further connected with a pull rod fixing pin, and a handle is arranged on the material shaft mounting seat. After the material roll is used up, the handle on the material shaft mounting seat is lifted manually, and the material seat is positioned by the pull rod fixing pin. After installing the material roll, the pull rod fixing pin is restored, and the material roll relies on its own weight to mesh with the driving shaft.

[0010] As an improvement of the feeding device of the present invention, a corner limit shaft and a first limit shaft are arranged on the fixing rod.

[0011] As an improvement of the feeding device of the present invention, the corner limit shaft is connected to the second connecting rod through the first connecting rod, and the first connecting rod can move up and down on the second connecting rod, and the second connecting rod can move horizontally or swing on the fixing rod.

[0012] As an improvement of the feeding device of the present invention, a long groove is arranged on the swinging rod, and a second limit shaft is arranged in the long groove.

[0013] As an improvement of the feeding device of the present invention, the swinging rod is arranged on the frame through a rotating pin, the swinging rod is further connected to the frame through a spring, and an arc-shaped plate is connected to the end of the swinging rod. A second sensor for detecting the arc-shaped plate is also arranged on the frame. When the second sensor detects the arc-shaped plate, it transmits a signal to the driving source to start the feeding operation.

[0014] As an improvement of the feeding device of the present invention, an arc-shaped limiting groove is provided on the arc-shaped plate, and the arc-shaped plate is fixed to the swing rod by a limiting screw passing through the arc-shaped limiting groove and embedded in the swing rod.

[0015] As an improvement of the feeding device of the present invention, a third limiting shaft, a fourth limiting shaft and a fifth limiting shaft are further provided on the frame.

[0016] As an improvement of the feeding device of the present invention, the frame includes a horizontal mounting plate, a vertical mounting plate and a main mounting plate. The main mounting plate is connected to the horizontal mounting plate through the vertical mounting plate, and the vertical mounting plate can move back and forth on the horizontal mounting plate, and the main mounting plate can move up and down on the vertical mounting plate.

[0017] As an improvement of the feeding device of the present invention, the driving source is a general motor, a stepping motor or a servo motor; the transmission mode between the driving source and the driving shaft is mechanical transmission, belt transmission, chain transmission, gear transmission or rear direct connection drive.

[0018] The present invention has a wide range of uses and can be used for the transportation of large rolls of double-sided tape, transparent tape, tear tape, foam tape, etc. It can directly skip the loading mechanism of the sticker head and enter the swing arm mechanism of the sticker head or directly enter the execution mechanism. Moreover, the present invention can also automatically detect whether the material roll is almost used up, and it is convenient and quick to replace the material roll without re-adjustment and has high efficiency.

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture (as shown in the attached drawings). If this specific posture changes, the directional indication will also change accordingly.

[0026] In addition, the descriptions involving "first", "second", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0027] As Figure 1-4 shown, a feeding device provided by the present invention includes a frame 1, a driving source 2, a driving shaft 3 arranged on the frame 1, a material roll 4, a material seat 5, a fixed rod 6 and a swing rod 7. The material roll 4 is loaded on the material seat 5. The driving source 2 drives the driving shaft 3 to rotate, and during operation, the material roll 4 meshes with the driving shaft 3. The material shaft of the material seat 5 is installed on a material shaft mounting seat 8, and a bearing seat is arranged on the material shaft mounting seat 8. The material shaft mounting seat 8 is arranged on a guide seat 9. A first sensor 10 is arranged at the lower end of the guide seat 9. The material tape on the material roll 4 is sent to the next process through the fixed rod 6 and the swing rod 7. During actual use, the overall feeding device is erected above the front of the sticker.

[0028] Preferably, there are two driving shafts 3 in the present invention, and its advantage is stable load-bearing. It is also possible to have only one driving shaft 3 or more driving shafts, and the effect of driving the material roll 4 can also be achieved.

[0029] By arranging the first sensor 10 at the lower end of the guide seat 9 in the present invention, and during operation, the material roll 4 and the driving shaft 3 always remain in a meshing state, it can ensure that the linear velocity of the conveyed tape is always consistent. During the conveying process of the material roll 4, as the material roll 4 becomes smaller and smaller, the material shaft mounting seat 8 for installing the material shaft moves downward along the guide seat 9 until the first sensor 10 senses the material shaft mounting seat 8, indicating that the material roll 4 is almost conveyed. The first sensor 10 feeds back a warning signal (or a production line stop signal), prompting to prepare to replace the large roll of material. In this way, it is not necessary for production personnel to always pay attention to whether the material roll is almost used up, reducing the pressure on production personnel and reducing the occurrence of production accidents.

[0030] Among them, the material seat 5 is also connected with a pull rod fixing pin 11, and a handle 12 is arranged on the material shaft mounting seat 8. After the material roll 4 is used up, the handle 12 on the material shaft mounting seat 8 is lifted manually, and the material seat is positioned by the pull rod fixing pin 11. After the material roll 4 is installed, the pull rod fixing pin 11 is restored, and the material roll 4 is engaged with the driving shaft 3 by its own weight.

[0031] A corner limit shaft 13 and a first limit shaft 14 are arranged on the fixed rod 6. Among them, the corner limit shaft 13 is connected to the second connecting rod 16 through the first connecting rod 15, and the first connecting rod 15 can move up and down on the second connecting rod 16, and the second connecting rod 16 can move horizontally or swing on the fixed rod 6. Therefore, the corner limit shaft 13 can freely adjust its height and the swing angle in the horizontal direction.

[0032] A long groove 17 is arranged on the swing rod 7, and several second limit shafts 18 are arranged in the long groove 17. The distance between the second limit shafts 18 can be adjusted and fixed in the long groove 17 according to requirements.

[0033] The swing rod 7 is arranged on the frame 1 through a rotating pin 19. The swing rod 7 is also connected to the frame 1 through a spring. An arc-shaped plate 33 is fixedly connected to the end of the swing rod 7. A second sensor 22 for detecting the arc-shaped plate 33 is also arranged on the frame 1. When the second sensor 22 detects the arc-shaped plate 33, it transmits a signal to the driving source 2 to start the feeding operation. The pulling force of the tape conveyance causes the swing rod 7 to swing around the rotating pin 19 and return to the initial position by the spring pulling force (the spring is omitted and not marked in the figure). Therefore, there are limits to the highest and lowest swing positions. In the non-working state, under the action of the spring force, the second sensor 22 cannot detect the arc-shaped plate 33. Once the conveyance causes swing and the arc-shaped plate 33 enters the detection range of the second sensor 22, a driving signal is output. In other words, when the second sensor 22 detects the swing of the swing rod 7 for feeding, it transmits a signal to the driving source 2 to smoothly convey the material roll 4. On the contrary, when it is detected that the material roll 4 does not need to be conveyed, the driving source 2 is stopped from driving.

[0034] An arc-shaped limit groove 21 is arranged on the arc-shaped plate 33. The arc-shaped plate 33 is fixed to the swing rod 7 through a limit screw 20 passing through the arc-shaped limit groove 21 and embedded in the swing rod 7. In this embodiment, at least two arc-shaped limit grooves 21 are arranged, so that the installation position of the arc-shaped plate 33 can be adjusted, and further the timing when the second sensor 22 detects the arc-shaped plate 33 can be adjusted. In other words, it is the amplitude of swing of the arc-shaped plate 33 that can be detected by the second sensor 22 before a driving signal is output.

[0035] The rack 1 is further provided with a third limiting shaft 23, a fourth limiting shaft 24 and a fifth limiting shaft 25. In this embodiment, there are two third limiting shafts 23, and a connecting plate 29 is connected to the ends thereof. The function of the fourth limiting shaft 24 is to limit the left - right transverse movement position of the tape, and it can be freely adjusted in the left - right position through a fixture. Specifically, the fourth limiting shaft 24 is connected to a connecting rod 31 through a slider 30, and the connecting rod 31 is fixed on the rack 1. The first limiting shaft 14, the second limiting shaft 18, the third limiting shaft 23, the fourth limiting shaft 24 and the fifth limiting shaft 25 all have 2 limiting rings.

[0036] The rack 1 includes a horizontal mounting plate 26, a vertical mounting plate 27 and a main mounting plate 28. The main mounting plate 28 is connected to the horizontal mounting plate 26 through the vertical mounting plate 27, and the vertical mounting plate 27 can move back and forth on the horizontal mounting plate 26, and the main mounting plate 28 can move up and down on the vertical mounting plate 27. The height adjustment of the main mounting plate 28 can be carried out through the vertical mounting plate 27, and the horizontal left - right adjustment can be carried out through the horizontal mounting plate 26. The main mounting plate 28 is mainly used for mounting various components.

[0037] The drive source 2 is a general motor, a stepper motor or a servo motor; the transmission mode between the drive source 2 and the drive shaft 3 is mechanical transmission, belt transmission, chain transmission, gear transmission or direct - drive at the rear.

[0038] In this embodiment, only one of the drive shafts 3 can be driven, or two or more drive shafts 3 can be driven. In this case, synchronous belt transmission is used, so there is a cover 32.

[0039] As Figure 5 shown, when in use, the material roll 5 is loaded on the material seat 6, the material roll 4 relies on its own weight to engage with the drive shaft 3, the drive source 2 starts to drive the drive shaft 3 to rotate, thereby driving the material roll 5 to rotate. The tape of the material roll 5 passes through two third limiting shafts 23, one fourth limiting shaft 24, then through the corner limiting shaft 13, then through at least one first limiting shaft 14 and at least one second limiting shaft 18, and finally through the fifth limiting shaft 25, and the tape is conveyed to the applicator head. The back (non - adhesive surface) of the tape of the material roll 5 is always in contact with these limiting shafts, and the tape needs to be flipped in some cases. The first limiting shaft 14 can pass through less or only the last one, but the second limiting shaft 18 must pass through at least one. Figure 5 The tape - winding method shown in

[0040] The adjustability of the present invention is strong and the applicable range is wide, and it is particularly suitable for the conveying of large-roll double-sided tapes, transparent tapes, easy-tear tapes, foam tapes, etc.

[0041] In this embodiment, the optimal solution adopted by the feeding device is to be placed vertically, and it can also be placed horizontally through optimization. As long as it is a transformation based on this similar principle and function, it should also be within the protection scope of this invention.

[0042] In the embodiments of the present invention, unless otherwise clearly specified and limited, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be directly connected, or indirectly connected through an intermediate medium.

[0043] This embodiment is the preferred embodiment of the present invention. Other designs and their processing technologies whose principles and basic structures are the same as or similar to those of this embodiment, as well as those with similar appearances, are all within the protection scope of this invention. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
