Description

Technical Field

[0001] The invention belongs to the field of textile machinery and equipment, and in particular relates to a double-channel conveying device and an automatic yarn feeding system. Background Art

[0002] In the industrial production process, yarn production generally includes the following steps: (1) Spinning stage: generally ring spinning, producing bobbin yarn, which includes a bobbin and yarn wound on the bobbin; (2) Winding process: the yarn is unwound from the bobbin, its defects are cleaned and it is rewound into a package, which contains a larger amount of yarn.

[0003] Before unwinding the yarn on the bobbin and winding it into a package yarn through a winder, the bobbin yarn needs to be placed at the unwinding station on the winder. Usually, the bobbin yarn is transported to the winder through a conveying device, and then the bobbin yarn is grabbed manually or by a robot to the unwinding mechanism of the winder for yarn unwinding.

[0004] In the prior art, the bobbin yarn is usually inserted into the upper hollow base, and the base is transported forward by a conveying device. The bobbin yarn is sleeved on the base so that the base carries the bobbin yarn forward. For example, the bobbin yarn conveying device described in the application with the published application number 2018110136862, the conveyor belt rotates in a cycle, and at the end, the empty base is turned around and transported to the conveyor belt running in the opposite direction to continue to sleeve the bobbin yarn. The base sleeved with the bobbin yarn continues to be transported and turns around to the conveyor belt on the other side so that the bobbin yarn is grabbed by the winder, thereby realizing the recycling of the base.

[0005] The prior art has the following problems in use: (1) When the winding machine grabs the bobbin yarn, the yarn may occasionally slip, causing the winding machine to fail to grab the bobbin yarn, but the conveyor belt below is in a continuous transportation state, resulting in the bobbin yarn still being transported to the other side of the base, and the base on the other side is mainly used for sleeved bobbin yarns, and the bobbin yarn still on the base will cause the sleeved yarn to fail, thereby interrupting the entire automated grabbing and sleeved yarn process, greatly increasing the equipment failure rate and manual remediation participation. (2) Due to the problems in (1), the guide groove for conveying the bobbin yarn is made into a forked shape in the prior art, but when the forked unit is divided from one channel into two channels, a guiding mechanism is often not provided, resulting in the bobbin yarn being stuck at the fork. No matter how smooth the guide groove is, the curved shape of the guide groove increases unpredictable friction resistance relative to the bobbin yarn. (3) The conveyor belt is too long. The base with the bobbin yarn can only be turned to the other side when it reaches the top or end, which greatly increases the waiting time, is not conducive to the grabbing and splicing of the bobbin yarn, and is not conducive to improving the efficiency of the entire automated process. Summary of the invention

[0006] In order to solve the above problems, the present invention provides a double-channel conveying device and an automatic yarn feeding system.

[0007] The technical solution of the present invention is:

[0008] A double-track conveying device comprises a frame, on which a first conveyor belt for conveying a material carrier is arranged, a first guide groove frame is arranged above the first conveyor belt, and a first guide groove is formed on the first guide groove frame for the material carrier to move along the conveying direction of the first conveyor belt; the double-track conveying device of the present invention also comprises a second conveyor belt opposite to the conveying path of the first conveyor belt, a second guide groove frame is arranged above the second conveyor belt, and a second guide groove is formed on the second guide groove frame for the material carrier to move along the conveying direction of the second conveyor belt.

[0009] The present invention also includes a third guide groove, wherein the first guide groove and the second guide groove form a third guide groove that is connected to each other, a first detection device for detecting whether the material carrier is loaded with material is provided near the third guide groove on the frame, and a first driving device is provided near the third guide groove on the frame, wherein the first driving device can switch the material carrier between the first guide groove and the second guide groove. The material carrier described in the present invention can be the base for placing bobbin yarn described in the background, and the material can be bobbin yarn. Of course, the present invention can also be used for other purposes and is not limited to the bobbin yarn of the conveyor belt seat and the empty base. The material carrier is as large as possible at the bottom and small at the top, and the upper part is movably clamped in the guide groove. Of course, the material carrier can also be set to other shapes that are convenient for sliding.

[0010] In the present invention, a plurality of third guide grooves can be provided, and the third guide grooves can be provided not only at the middle position of the present invention but also at other required positions, and the first driving device and the first detecting device also match the number and position of the third guide grooves. The material carrier is transported to the vicinity of the third guide groove by the first conveyor belt, and a first detecting device for detecting whether there is material on the material carrier is provided before the first driving device near the third guide groove. If the first detecting device detects and confirms that the material carrier is empty, the first driving device pushes the empty material carrier from the first conveyor belt through the third guide groove to the second guide groove on the second conveyor belt, and the empty material carrier continues to move forward in the reverse second guide groove until the empty material carrier is sleeved with material. The material carrier sleeved with material moves forward in the second guide groove until it reaches the vicinity of the third guide groove, and the first detecting device detects that the material carrier is sleeved with material, and the first driving device pushes the material carrier sleeved with material through the third guide groove to the first guide groove, and the material carrier sleeved with material is driven by the reverse first conveyor belt and moves forward in the first guide groove, and this cycle repeats.

[0011] The first detection device is arranged before the first driving device along the moving direction of the first conveyor belt or the second conveyor belt as a standard, the action direction of the first driving device is directly opposite to the direction in which the material carrier moves out of the second guide groove or the first guide groove through the third guide groove path, the first driving device is a rodless cylinder, and the first detection device is a photoelectric sensor. The position of the first detection device in the present invention is in front to facilitate detection of whether the material carrier carries material, and inform the first driving device to act. The rodless cylinder of the present invention is convenient and fast, greatly saving installation space.

[0012] Preferably, the first guide groove includes a plurality of guide groove units, each of which includes a double channel portion and a single channel portion interconnected with each other, and a second detection device for detecting whether the material carrier carries material is provided on one side channel of the double channel portion, and the second guide groove is a linear guide groove. In the present invention, the second detection device is arranged on the outer channel of the double channel portion, and of course, it can also be arranged at the inner channel of the double channel portion as required. The second detection device is used to detect whether there is material on the material carrier. If it is determined that there is material, the material is grabbed away by an external gripper or other equipment, such as a manipulator, and only the material carrier is left to continue moving forward. In the present invention, the part at the fork where the single channel portion branches to the double channel portion is a curved curve. In order to allow the material carrier to enter the outer channel of the double channel portion first, the curve is bent inward so that the running material carrier moves toward the outside of the double channel portion under the action of inertia. Of course, as long as the operation of different channels without affecting each other is achieved and they converge into one channel, the guide groove unit using this cross-circulation method belongs to the scope of the present invention, and the guide groove unit includes a three-channel portion and a single channel portion.

[0013] Preferably, a rotating member is provided at the entrance where the single channel portion communicates with the double channel portion, and the rotating member is partially located in the double channel portion. When the rotating member contacts the moving material carrier, it rotates in contact. The rotating member contacts the moving material and rotates in contact, and the contact rotation guides the movement of the material carrier. The rotating member here can be a miniature bearing or a shoulder screw plus a sleeve, etc. The axis of the rotating member is perpendicular to the upper plane of the first guide groove, or the axis of the rotating member is in the same direction as the axis of the material carrier. The rotating member is partially located in the fork of the double channel portion, that is, a part of the rotating member protrudes out of the fork entrance of the double channel portion. With this design, the material carrier can first contact the rotating member and the rotating member rotates to guide the material carrier to move, thereby preventing the material carrier from being blocked or scratched.

[0014] Preferably, a lower curved plate is further provided below the side edge of the first guide groove, and the side edge of the lower curved plate is a smooth curved surface, and the smooth curved surface of the side edge of the lower curved plate contacts the moving material carrier and guides the material carrier to move. Here, the lower curved plate contacts the material carrier first, and at this time, the material carrier does not touch the clamping edges on both sides of the first guide groove, and the smooth curved surface of the side edge of the lower curved plate guides the material carrier to move, thereby preventing the material carrier from being blocked.

[0015] Preferably, a plurality of observation ports are provided on the upper surface and the left and right sides of the first guide slot frame and the second guide slot frame; the first guide slot and the second guide slot are both made of segmented aluminum alloy profiles. The plurality of observation ports are conducive to observing the position and state of the material carrier. At the same time, because the first guide slot is filled with material carriers loaded with materials, and because the material is bobbin yarn, there are thread ends on the bobbin yarn, and the thread ends will always fall or wrap around a part of the first guide slot frame or the second guide slot frame during operation, the plurality of observation ports can facilitate the airflow to pass through when the air gun is flushing the first guide slot, the second guide slot, and the first guide slot frame and the second guide slot frame, so as to blow away the thread ends or other debris. For debris that is not easy to flush away by the air gun, the plurality of observation ports facilitate manual clamping. The aluminum alloy profile in the present invention is convenient for batch production and because it is made with the same mold, it is convenient to align the respective first guide slots and the second guide slots during installation.

[0016] Preferably, the second detection device is a photoelectric sensor, which is arranged on both sides of a bracket on the outer channel of the dual-channel part, and the bracket is an inverted U-shaped bracket, which is installed on both sides of the outer channel of the dual-channel part. A door-shaped bracket is also arranged at the front entrance of the inverted U-shaped bracket, and the lower space formed by the door-shaped bracket and the inverted U-shaped bracket allows the material carrier to pass smoothly while the material is blocked from passing. The photoelectric sensor here is a through-beam photoelectric sensor, which makes the detection result more accurate. The inverted U-shaped bracket is convenient for installing the photoelectric through-beam sensor, and the door-shaped bracket reinforces the inverted U-shaped bracket. Guide plates are also arranged on both sides of the door-shaped bracket, and the guide plates are trumpet-shaped openings. The guide plates with trumpet-shaped openings allow the material carrier to pass more smoothly.

[0017] The present invention also provides an automatic yarn feeding system, comprising at least one or a double-channel conveying device, and at least one feeding station, wherein the feeding station is the bracket as described above, the height of the bracket is lower than the height of the material on the material carrier, and the second detection device is located at the feeding station. When the material arrives at the feeding station, because the height of the bracket is lower than the height of the material, the material is prevented from being grabbed by an external grabbing manipulator at the feeding station.

[0018] Preferably, there are multiple double-track conveying devices, and the first guide grooves and the second guide grooves of the multiple double-track conveying devices are connected end to end respectively; connected end to end to form a straight line or other required shape. In the middle section of the automatic yarn feeding system, multiple double-track conveying devices of the first driving devices in different orientations are staggered, that is, in the double-track conveying device of the odd-numbered sections, the first driving device is located at the outside of the second guide groove, and the first driving device pushes the base with bobbin yarn in the second guide groove into the first guide groove, and in the double-track conveying device of the even-numbered sections adjacent to it, the first driving device is located at the outside of the first guide groove, and the first driving device pushes the base without bobbin yarn in the first guide groove into the second guide groove; in the first section of the automatic yarn feeding system, the third guide groove is located at the head of the double-track conveying device, and there is no first driving device, so that it is the second driving device that moves the material carrier from the second guide groove to the first guide groove; in the tail section of the automatic yarn feeding system, the third guide groove of the double-track conveying device is located at the tail of the double-track conveying device, and there is no first driving device, so that it is the second driving device that moves the material carrier from the first guide groove to the second guide groove. In the present invention, the first driving devices of adjacent double-track conveying devices are arranged at opposite positions. This design can improve the efficiency and accuracy of the movement of the material carrier, and avoid excessive accumulation of the material carrier and the material. In the present invention, the first guide grooves and the second guide grooves of multiple double-track conveying devices are connected end to end to form an annular channel. The material carrier circulates in the annular guide groove, and the material carrier is continuously sleeved with materials or the sleeved materials are continuously taken away, thereby realizing the recycling of the material carrier and improving the work efficiency.

[0019] Furthermore, in addition to the third guide groove at the head end, the first section of the double-track conveying device of the present invention can also be provided with a third guide groove and a corresponding first detection device and a first driving device in the middle part of the first section of the double-track conveying device. The added third guide groove improves the conveying efficiency.

[0020] Preferably, at the tail section of the automatic yarn feeding system, the double-channel conveying device has two third guide grooves, namely the third-first guide groove and the third-second guide groove. The third-first guide groove guides the material carrier of the first guide groove to the second guide groove from the inner side of the tail end of the double-channel portion, and the third-second guide groove guides the material carrier of the first guide groove to the second guide groove from the outer side of the tail end of the double-channel portion, and the third-first guide groove and the third-second guide groove are both provided with a second drive. In the automatic yarn feeding system of the present invention, there are two third guide grooves of the double-channel conveying device at the tail section of the automatic yarn feeding system. This design facilitates multiple bases to enter the second guide groove through the third guide groove at the same time, so as not to cause congestion and jamming or overturning.

[0021] Furthermore, in addition to the third guide groove being provided at the tail end, the double-track conveying device of the tail section of the present invention can also provide the third guide groove and the corresponding first detection device and first driving device in the middle part of the double-track conveying device of the tail section. The added third guide groove improves the conveying efficiency.

[0022] Preferably, the second drive is a rotating body arranged between the first conveyor belt and the second conveyor belt, the axis of the rotating body is parallel to the conveying direction of the first conveyor belt and the second conveyor belt, and the width of the gap between the first conveyor belt and the second conveyor belt is smaller than the width of the material carrier. The rotating body here can be a bearing or a sleeve. When the base moved by the conveyor belt reaches the second drive, there is no space to continue moving forward, but the conveyor belt is still rotating. The rotation thrust of the conveyor belt moves the base to the rotating body, and the rotating body rotates, and the base moves to the conveyor belt on the other side via the rotating body being rotated.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] The present invention can enable bases with or without bobbin yarns to be placed in correct positions in a timely manner without any jamming or blocking during the process; even if an empty base or a base with bobbin yarns is misplaced, the automatic yarn loading system of the present invention can automatically correct the incorrect position of the empty base or the base with bobbin yarns; the entire process does not require manual intervention or intervention, and automation is completely and smoothly realized.

[0025] The double-track conveying device in the middle part of the automatic yarn feeding system of the present invention is also provided with a third guide groove. The provision of the third guide groove saves the running time of the empty base or the base with bobbin yarn with a stroke error, improves the error correction efficiency, fundamentally saves the time of the entire process, and improves the work efficiency and work quality. The provision of the third guide groove timely adjusts the position of the empty base or the base with bobbin yarn, and also ensures the correctness and continuity of the actions performed in conjunction with the entire automated process.

After the second detection device detects whether there is material 18 on the base, if there is material 18, the external manipulator grabs the material 18. The material carrier 1 without material 18 continues to move forward to the third guide groove 4e. The first detection device 5 detects that there is no material 18. Then the first drive device 6 pushes the material carrier 1 to move to the second conveyor belt 3 running in the opposite direction on the other side. The empty material carrier 1 continues to move forward in the second guide groove 3e and is sleeved with material 18 at the corresponding position. The material carrier 1 with material 18 continues to move forward in the second guide groove 3e. When passing through the third guide groove 4e, the first detection device 5 detects that it carries material 18. Then the first drive device 6 pushes the material carrier 1 to move to the first conveyor belt 2 running in the opposite direction on the other side. If there is material 18 that runs into the wrong channel or an empty base, it will be pushed back to the corresponding second guide groove 3e or first guide groove 2e after being detected by the first detection device 5 at the corresponding third guide groove 4e.
