Description

Technical Field

[0001] This invention relates to the field of cable tie machine technology, and more specifically to a material feeding mechanism for cable tie machines. Background Technology

[0002] Cable ties, as the name suggests, are straps used to bundle things together. They are designed with a backstop function, meaning they can only be tightened further as they are tied. They are commonly used in cables for electromechanical products, such as computer and electronic products, and automotive wiring harnesses.

[0003] For the cable tie conveying mechanism of a cable tie machine, patent announcement number CN213384876U discloses a cable tie conveying mechanism for a cable tie machine, which specifically discloses a feeding mechanism for conveying cable ties to a pushing mechanism, a pushing mechanism for pushing the cable ties one by one, and a guiding mechanism for guiding the pushed cable ties out one by one; the pushing mechanism includes a pushing cylinder, a pushing seat, a guide rail, a pushing rod, and a pushing block; the pushing seat is fixed on the output shaft of the pushing cylinder and is slidably disposed on the guide rail; a pushing groove extending in the front-back direction is provided on one side of the pushing block, and the pushing groove is used to place the cable ties; the pushing rod is fixed to one side of the pushing seat and is located on the pushing groove; the front end of the pushing rod is L-shaped to limit the cable tie, and the pushing rod is used to push the cable tie. A guide block is provided at the end of the pusher block, and the front end of the pusher groove extends to the guide block. A trapezoidal discharge groove is formed in the guide block, and a discharge port is formed at the end of the discharge groove. The guide block is used to cooperate with the guiding mechanism. A fiber optic sensor for detecting the cable ties in place is also provided on the pusher block. The feeding mechanism includes a feeding tray, a support plate, a distributing gear, a motor, and a transparent limiting plate. The feeding tray is fixedly installed, and a groove is provided on the feeding tray, with one end of the groove communicating with the pusher groove. The support plate is fixed on the feeding tray, and the motor is fixed on the support plate. The distributing gear is fixed on the output shaft of the motor, and the upper end of the distributing gear passes through the groove. The transparent limiting plate is fixed on the feeding tray, and the transparent limiting plate is located above the groove.

[0004] However, the cable tie conveying mechanism of the aforementioned cable tie machine still has some drawbacks. For example, during the cable tie conveying process, a pusher cylinder drives a pusher rod to move the cable tie on the pusher groove to the guide block, and the guide mechanism blows the cable tie to the next step. Since the cable ties conveyed by the feeding mechanism are sequential and continuous, when the pusher rod pushes the first cable tie on the pusher groove, it acts as a separator between the first and second cable ties, thus preventing the second cable tie from entering the pusher groove, i.e., achieving material separation. Furthermore, since one side and the top of the pusher groove are open, if the cable tie is already at the tail end during the feeding mechanism's conveying process... In cases of slight bending, such as a slight upward or downward bend at the tail, using a pusher rod for material distribution can easily cause the cable tie to bend further during movement due to contact with the bottom of the pusher groove or the guide block. This can lead to the cable tie getting stuck on the guide block due to its increased maximum height, preventing it from being smoothly discharged by the guiding mechanism, thus causing a jam and affecting the normal conveying of the cable tie. In addition, if the cable tie bends further during movement, its own elasticity may cause it to pop directly out of the pusher groove during the material distribution process, resulting in material detachment. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this invention is to provide a material distribution mechanism for cable tie feeding in a cable tie machine. By improving the material distribution method, the cable tie is less prone to bending during material distribution and subsequent movement, and is less prone to jamming during transmission, thereby reducing the occurrence of jamming in the equipment. In addition, it also makes it less likely for the cable tie to come off during transmission, thus ensuring the stability of the cable tie movement.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] A cable tie feeding mechanism for a cable tie machine includes a feeding assembly for outputting cable ties; and a distributing assembly for cooperating with the feeding assembly. The distributing assembly includes a distributing cover plate and a distributing drive device and a distributing base respectively fixedly disposed thereon. A protrusion is provided on one side of the distributing base, and a distributing groove extending in a front-back direction is formed on the top surface of the protrusion. The distributing cover plate is mounted on the output end of the distributing drive device, and the distributing drive device can drive the distributing cover plate to move back and forth on the distributing groove. During the rearward movement, the distributing cover plate can cooperate with the side of the distributing base and the bottom surface of the distributing groove to form a distributing cavity extending back and forth for accommodating cable ties.

[0008] Furthermore, it also includes a blowing assembly; the blowing assembly is fixedly installed and can cooperate with the dispensing cavity to blow the cable ties inside the dispensing cavity backward.

[0009] Furthermore, the blowing assembly includes a positioning seat fixed below the material distribution cover and an air blowing pipe installed on the positioning seat, with the air outlet of the air blowing pipe facing the front end of the material distribution trough; a connecting part is provided at the rear end of the material distribution trough, and an outlet corresponding to the material distribution cavity is provided in the connecting part; the positioning seat and the connecting part are respectively located at the two ends of the material distribution cavity, so that the positioning seat and the connecting part can respectively form the front and rear sidewalls of the material distribution cavity, and the perimeter of the material distribution cavity is either sealed or unsealed; the gas blown out by the air blowing pipe can be used to blow the cable ties in the material distribution cavity toward the outlet.

[0010] Furthermore, a pressure sensor is connected to the air blowing pipe. The pressure sensor is in communication with the gas inside the air blowing pipe. The pressure sensor is calibrated and set to a pressure value when there is no jamming of the cable tie. When there is no jamming, the pressure sensor detects a pressure value below the set pressure value. When jamming occurs, the pressure sensor detects a pressure value higher than the set pressure value, and when it detects a pressure value higher than the set pressure value, the pressure sensor outputs an electrical signal.

[0011] Furthermore, a downwardly extending side plate is provided on the side of the material distribution cover away from the material distribution base, which is used to cooperate with the side of the material distribution base and the bottom surface of the material distribution groove, so that the side plate can be used to form one side wall of the material distribution cavity.

[0012] Furthermore, a front-to-back extending baffle is provided on the side of the material distribution trough, and the baffle and the material distribution base form an area for limiting the two sides of the cable tie; the bottom surface of the side plate abuts against the top surface of the baffle; a notch is left between the front end of the material distribution trough and the front end of the baffle for the head of the cable tie to pass through; a downward extending blocking plate is provided at the front end of the side plate for cooperating with the notch, so that the blocking plate can be used to seal the notch after the material distribution cover plate moves backward into place.

[0013] Furthermore, it also includes a material blocking assembly; the material blocking assembly includes a material blocking block and a material blocking drive device for driving the material blocking block to move up and down; a through hole is opened on the bottom surface of the material distribution groove near the front end; the upper end of the material blocking block passes through the through hole; the material blocking drive device can be used to drive the upper end of the material blocking block to extend upward out of the through hole and to block the head of the cable tie.

[0014] Furthermore, a pressure plate is provided on the rear end of the material distribution cover plate, located above the material distribution groove, for limiting the head of the cable tie.

[0015] Furthermore, the material distribution cover can be slidably mounted on the material distribution base, and a buffer damper that cooperates with the material distribution cover is provided at the end of the material distribution base to buffer the material distribution cover.

[0016] Furthermore, a sliding groove with a narrow upper end and a wide lower end, extending forward and backward, is provided on the material distribution base; a slider is provided on the material distribution cover plate for fitting and engaging within the sliding groove. The sliding groove and slider are used to ensure the stability of the material distribution cover plate's movement.

[0017] The beneficial effects of this invention are as follows:

[0018] This invention improves the material distribution method, creating a material distribution cavity after the material distribution cover moves backward. The first cable tie is accommodated in this cavity and separated from subsequent cable ties, thus achieving material distribution. The cable tie is then blown backward by the blowing assembly to the connecting part and finally moves to the next step. Furthermore, during the formation of the material distribution cavity (i.e., as the material distribution cover moves backward), the cable tie, which is initially slightly bent at the tail, can be compressed to a certain extent, limiting its maximum height to the height of the material distribution cavity. Moreover, due to the limiting effect of the material distribution cavity during and after material distribution, the cable tie is less likely to become increasingly bent, reducing the risk of jamming during transport and minimizing the possibility of the cable tie slipping out, thereby ensuring the stability of the cable tie transport.

[0029] The invention will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely exemplary and does not limit the scope of protection of the invention.

[0030] like Figures 1-8As shown, a cable tie feeding and separating mechanism for a cable tie machine includes a feeding assembly 1 for outputting cable ties; and a separating assembly 2 for cooperating with the feeding assembly. The separating assembly 2 includes a separating cover plate 21 and a separating drive device 22 and a separating base 23 respectively fixedly disposed. A protrusion is provided on one side of the separating base 23, and a separating groove 24 extending in the front-back direction is formed on the top surface of the protrusion. The separating cover plate 21 is installed on the output end of the separating drive device 22, and the separating drive device 22 can drive the separating cover plate 21 to move back and forth on the separating groove 24. During the backward movement, the separating cover plate 21 can cooperate with the side of the separating base 23 and the bottom surface of the separating groove 24 to form a separating cavity 25 extending in the front-back direction for accommodating cable ties. Thus, the separating cavity 25 can be used to separate the first and second cable ties in the sequentially fed cable ties, that is, to form a separating mechanism. The above configuration allows the feeding assembly 1 to easily deliver the cable ties into the distribution slot 24, enabling the output of the cable ties. Then, the distribution drive device 22 can drive the distribution cover plate 21 to move backward, thereby forming a distribution cavity 25 that houses the cable ties on the distribution slot 24, where the distribution cover plate 21 and the distribution base 23 cooperate with the protrusion. This completes the distribution of the first cable tie to the remaining cable ties. Furthermore, during the formation of the distribution cavity 25, i.e., as the distribution cover plate moves backward, the cable ties, which are bent at the tail, can be pressed down to a certain extent, limiting their maximum height to the height of the distribution cavity 25. Moreover, during the distribution process and subsequent movement after distribution, the cable ties are less likely to become increasingly bent due to the limitation provided by the distribution cavity 25. This prevents the cable ties from jamming during transport and avoids cable tie detachment, ensuring the stability of the cable tie transport.

[0031] The structure of the feeding component 1 is based on existing technology and will not be described in detail here.

[0032] like Figure 5 As shown, it also includes a blowing assembly 3; the blowing assembly 3 is fixedly installed and can cooperate with the dispensing cavity 25 to blow the cable tie in the dispensing cavity 25 backward, so that the cable tie can be sent to the next step by the blowing assembly 3.

[0033] like Figure 3 and Figure 5As shown, the blowing assembly 3 includes a positioning seat 32 fixed below the distribution cover plate 21 and an air blowing pipe 31 installed on the positioning seat 32. The air outlet of the air blowing pipe 31 faces the front end of the distribution groove 24, while the air inlet of the air blowing pipe 31 is used to connect to an external air supply device. A connecting part 7 is provided at the rear end of the distribution groove 24, and an outlet 71 corresponding to the distribution cavity 25 is provided in the connecting part 7. Specifically, the size of the inlet port of the outlet 71 should be set to be consistent with the size of the outlet port of the distribution cavity 25, so as to achieve a better blowing effect and reduce the probability of jamming. The positioning seat 32 and the connecting part 7 are located at the two ends of the distribution cavity 25, so that the positioning seat 32 and the connecting part 7 can respectively form the front and rear side walls of the distribution cavity 25, and the distribution cavity 25 is either sealed or unsealed. The gas blown out by the air blowing pipe 31 can be used to blow the cable ties in the distribution cavity 25 toward the outlet 71, that is, toward the connecting part 7. Because of the limiting of the material distribution cavity 25, the cable tie is less likely to bend as it moves through the blowing assembly 3 to the connecting part 7, so that the cable tie can be smoothly inserted into the connecting part 7 without jamming, and the blowing assembly 3 can finally blow the cable tie to the next step.

[0034] It should be noted that when the material distribution cavity 25 is designed to be unsealed, it means that there may be some gaps between the components forming the material distribution cavity 25, but there will only be slight air leakage, and there will not be a large amount of air leakage, so as to prevent most of the gas blown out by the air blowing pipe 31 from leaking to the outside and causing the cable ties to not be blown quickly and stably. When the material distribution cavity 25 is designed to be sealed, it means that except for the air inlet pipe 31 and the material outlet 71, the other parts are sealed, so that the gas blown out by the air blowing pipe 31 can only be discharged from the material outlet 71, thereby ensuring the effect of air intake and exhaust.

[0035] Preferably, the gas in the air blowing pipe 31 is compressed air.

[0036] like Figure 8As shown, a pressure sensor 33 is also connected to the air blowing pipe 31. The pressure sensor 33 is connected to the gas in the air blowing pipe 31. The pressure sensor 33 is calibrated and set to a pressure value when there is no jamming of the cable tie. When there is no jamming, the pressure sensor 33 detects a pressure value below the set pressure value. When jamming occurs, the pressure sensor 33 will detect a pressure value higher than the set pressure value. When the pressure sensor 33 detects a pressure value higher than the set pressure value, it will output an electrical signal. Specifically, the electrical signal output by the pressure sensor 33 will be input to the control center. Therefore, by setting pressure sensor 33, it can be used to detect whether the cable tie is stuck in the material distribution cavity 25. When the cable tie is stuck, the air blowing pipe 31 will not be able to blow away the cable tie in the material distribution cavity 25, and the gas will not be able to be discharged smoothly. This will eventually cause the gas to accumulate pressure and be detected by pressure sensor 33 as an increase in air pressure value. When pressure sensor 33 detects that the air pressure exceeds the preset air pressure value within a few milliseconds after the air blowing pipe 31 blows air (pressure sensor 33 will not detect when the air blowing just begins), it will output an electrical signal to notify the control center to activate the alarm device and issue a warning, so that the staff can deal with the jammed equipment in a timely manner.

[0037] like Figure 8 As shown, a solenoid valve 34 with a control switch is also connected to the air blowing pipe 31, so that the opening or closing of the air blowing pipe 31 can be easily controlled.

[0038] like Figures 4-8 As shown, preferably, a side plate 211 extends downward from the side of the distributing cover plate 21 away from the distributing base 23 to engage with the side of the distributing base 23 and the bottom surface of the distributing groove 24. This allows the side plate 211 to form one side wall of the distributing cavity 25. Specifically, the side plate 211, in conjunction with the side of the distributing base 23, the bottom surface of the distributing groove 24, the bottom surface of the distributing cover plate 21, the positioning seat 32, and the connecting portion 7, can respectively form the four sides of the distributing cavity 25, enabling the distributing cavity 25 to be formed quickly, facilitating the subsequent operation of the blowing assembly 3. It should be noted that, in the initial state, the bottom surface of the distributing cover plate 21 is slightly higher than the maximum height of the cable tie to prevent the distributing cover plate 21 from dragging the cable tie when moving.

[0039] like Figures 4-7As shown, in this embodiment, in order to facilitate the limiting of the side plate 211, a front-to-back extending baffle 26 can be provided on the side of the material distribution groove 24. The baffle 26 and the material distribution base 23 form an area for limiting the two sides of the cable tie. The bottom surface of the side plate 211 abuts against the top surface of the baffle 26. A notch 27 is left between the front end of the material distribution groove 24 and the front end of the baffle 26 for the head of the cable tie to pass through. A blocking plate 214 extending downward and cooperating with the notch 27 is also provided at the front end of the side plate 211. The blocking plate 214 can be used to seal the notch 27 after the material distribution cover plate 21 moves backward into place, preventing the subsequent cable ties from continuing to move into the material distribution groove 24. Therefore, the side plate 211 and the blocking plate 214 can play the role of separating the first and second cable ties arranged in sequence, realizing material distribution. By setting a notch 27, the head of the cable tie can pass through, so as to facilitate feeding. Of course, when the feeding component 1 conveys the cable tie to the distribution groove 24, the height of the baffle 26 is generally required to be lower than the height of the strip part of the cable tie, so as to prevent the cable tie from not being able to move smoothly into the distribution groove 24.

[0040] like Figures 3-5 As shown, it also includes a baffle assembly 4; the baffle assembly 4 includes a baffle block 41 and a baffle drive device 42 for driving the baffle block 41 to move up and down; a through hole 43 is opened on the bottom surface of the distribution groove 24 near the front end; the upper end of the baffle block 41 passes through the through hole 43; the baffle drive device 42 can be used to drive the upper end of the baffle block 41 to extend upward out of the through hole 43 and to block the head of the cable tie. By setting the baffle assembly 4, the cable tie can be positioned after it moves into place on the distribution groove 24, preventing the cable tie from swinging. In specific use, when the feeding assembly 1 conveys the cable tie to the distribution groove 24, the baffle drive device 42 drives the baffle block 41 to move upward until the upper end of the baffle block 41 passes through the through hole 43 and blocks the rear end of the cable tie head, thus using the baffle block 41 to block the cable tie.

[0041] like Figures 4-6 As shown, a pressure plate 212 is also provided on the rear end of the distribution cover plate 21, located above the distribution groove 24, for limiting the head of the cable tie. The pressure plate 212 can then lightly press down on the head of the cable tie to limit its movement. Alternatively, the pressure plate 212 can cooperate with the stop block 41 to limit the cable tie, thereby improving its stability. Furthermore, the pressure plate 212 can be positioned slightly higher than the head of the cable tie to avoid pressing down on it and causing the distribution cover plate 21 to move uncomfortably.

[0042] like Figure 2 and Figure 5As shown, a fiber optic sensor 5 is also provided on the material distribution base 23, extending into the material distribution slot 24 and used to detect whether the cable ties are in place. By setting this fiber optic sensor 5, it is possible to easily sense whether the cable ties on the material distribution slot 24 have moved into place, so that the material distribution drive device 22 and the material blocking drive device 42 can be activated.

[0043] like Figure 4 As shown, preferably, the material distribution cover 21 can be slidably mounted on the material distribution base 23, thereby improving the movement stability of the material distribution cover 21. At the end of the material distribution base 23, a buffer damper 6 that cooperates with the material distribution cover 21 is also provided. Thus, when the material distribution cover 21 slides on the material distribution base 23, the buffer damper 6 can play a limiting and buffering role, which can further improve the reliability of the overall mechanism and extend its service life.

[0044] like Figure 4 and Figure 8 As shown, preferably, the material distribution base 23 is provided with a groove 231 that is narrower at the top and wider at the bottom and extends forward and backward; the material distribution cover plate 21 is provided with a slider 213 that is fitted into the groove 231, that is, the shape of the slider 213 matches the shape of the groove 231. By providing corresponding grooves 231 and sliders 213, it can be ensured that the material distribution cover plate 21 will not fall out during movement. Of course, this structure can also improve the stability of the material distribution cover plate 21.

[0045] like Figure 1 As shown, specifically, the buffer damper 6 is installed at the end of the slide 231.

[0046] Preferably, the feeding assembly 1, the dispensing drive device 22, the dispensing base 23, the positioning seat 32, the blocking drive device 42, and the connecting part 7 are all fixedly installed on a fixed plate 8.

[0047] In this embodiment, both the material distribution cover plate 21 and the material blocking block 41 are cylinders to facilitate driving. However, those skilled in the art should know that if the material distribution drive device 22 and the material blocking drive device 42 can achieve the same effect using other structures, then other structures can also be used for the material distribution drive device 22 and the material blocking drive device 42, which will not be specifically exemplified here.

[0048] The specific operating principle of this invention is described below to help you understand it:

[0049] First, multiple cable ties are conveyed from the vibratory feeder to the feeding assembly 1; then, the feeding assembly 1 drives the multiple cable ties to be conveyed sequentially to the distribution trough 24; when the fiber optic sensor 5 senses the first cable tie on the distribution trough 24, the blocking drive device 42 drives the blocking block 41 to move upward until the upper end of the blocking block 41 blocks the head of the cable tie 9, and at this time the pressure plate 212 is also almost pressed against the top surface of the head of the cable tie 9; immediately afterward, the distribution drive device 22 drives the distribution cover plate 21 to move backward until it contacts the buffer damper 6. When the distribution cover plate 21 moves into place, it forms A material distribution cavity 25, i.e., the first cable tie 9 on the material distribution trough 24, is located within the material distribution cavity 25. Simultaneously, the side plate 211 and the blocking plate 214 separate the subsequent second cable tie 9 from the first cable tie 9 within the material distribution cavity 25, creating a material distribution effect. Then, the solenoid valve 34 opens, and the material blocking drive device 42 drives the material blocking block 41 to descend, causing gas to be blown out through the air blowing pipe 31 into the material distribution cavity 25, simultaneously moving the cable tie 9 within the material distribution cavity 25 towards the discharge port 71 until it is discharged at the discharge port to the next step, thus completing the transfer of one cable tie. When a jam occurs, the pressure sensor 33 senses the increase in air pressure and sends an electrical signal to the control center. After the transfer of the first cable tie is completed, the material distribution cover plate 21 and the solenoid valve 34 reset, allowing the second cable tie 9 to be input into the material distribution trough 24, and then a new round of cable tie transfer begins.

[0050] This invention is not limited to the above-described embodiments. If any modifications or variations to this invention do not depart from the spirit and scope of this invention, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this invention, then this invention also intends to include such modifications and variations.
