Description

Technical Field

[0001] This utility model belongs to the field of conical object conveying technology, and in particular relates to a device for conveying conical objects by airflow. Background Technology

[0002] In the textile industry, the yarn delivered by spinning mills uses thin-walled, lightweight, conical paper yarn tubes, and the finished pagoda-shaped yarn in the textile thread-making industry uses a large number of injection-molded thin-walled, lightweight conical rubber cores. These conical objects (hereinafter referred to as conical objects) need to be transported to designated areas by corresponding airflow conveying equipment during the collection and processing process.

[0003] In existing technologies, most conical objects are transported via pipelines. However, these conical objects are prone to nesting with each other. During pipeline transport, conical objects can easily nest into long strip structures. These long strip structures nested within the conical objects can cause blockages in the bends of the pipeline, preventing the conical objects from being transported normally. Utility Model Content

[0004] This invention provides a device for conveying conical objects using airflow, aiming to solve the problem that the conical objects cannot be conveyed normally because the excessively long structure of the conical object becomes blocked in the curved area of ​​the pipe after being nested.

[0005] This invention is implemented as follows: a device for conveying a conical object using airflow, comprising:

[0006] An input pipe, an output pipe, and a conveying mechanism are provided, wherein the input pipe and the output pipe are respectively connected to both ends of the conveying mechanism;

[0007] The conveying mechanism includes a first three-way valve and a second three-way valve. The end of the first three-way valve that is away from the ground is connected to the input pipe, and the end of the second three-way valve that is close to the ground is connected to the output pipe.

[0008] A buffer pipe and a storage pipe are provided between the first tee and the second tee. The buffer pipe and the storage pipe are equipped with a gripper unit. After the conical object input into the input pipe passes through the first tee and fills the storage pipe, the gripper unit blocks the conical object between the buffer pipe and the storage pipe. The conical object located in the storage pipe slides into the output pipe through the second tee under its own weight.

[0009] Preferably, a second gate is provided between the first tee and the buffer pipe, and a fourth gate is provided between the storage pipe and the second tee.

[0010] Preferably, the connection port on the side wall of the first tee is connected to the exhaust fan, and the connection port on the side wall of the second tee is connected to the blower.

[0011] Preferably, a first gate is provided at the first tee sidewall connection port, and a third gate is provided at the second tee sidewall connection port.

[0012] Preferably, the first gate includes a locking seat, a base plate, a first push rod, and a gate plate. The locking seat is disposed on the base plate, and a conveying channel is provided between the locking seat and the base plate. The locking seat has a locking cavity that communicates with the conveying channel. The gate plate extends into the locking cavity from the first push rod and blocks the conveying channel.

[0013] Preferably, the first gate, the second gate, the third gate, and the fourth gate have the same structure.

[0014] Preferably, the gripper unit includes grippers, an outer cover plate, and a support plate. The outer cover plate has a U-shaped structure, and the outer cover plate and the support plate form an operating cavity. The grippers are arranged in the operating cavity and grip the conical object passing through the operating cavity.

[0015] Preferably, both the outer cover plate and the support plate are provided with circular material inlets, the buffer tube is connected to the material inlet on the outer cover plate, and the end of the first tee closer to the second tee is connected to the end of the buffer tube away from the second tee.

[0016] Preferably, the conveying mechanism further includes a support column and a pallet, the pallet being disposed in the middle section of the support column, the fourth gate being mounted on the pallet, and the second gate being mounted on the top of the support column.

[0017] Compared with the prior art, the embodiments of this application have the following main advantages:

[0018] The device for conveying conical objects by airflow provided by this utility model ensures that the length of the conical object entering the output pipe is maintained within a certain range by switching between the interception state of the gripper unit and the opening and closing state of the gate structure. This avoids the situation where too many conical objects form a long structure due to nesting and travel in the pipe, causing the conical object to be unable to pass through the subsequent curved output pipe, resulting in blockage of the output pipe in the curved area and poor conveying of the conical object.

[0030] This utility model embodiment provides a device for conveying a conical object using airflow, such as... Figures 1-7 As shown, the device for conveying a conical object by airflow includes:

[0031] The system includes an input pipe 120, an output pipe 110, and a conveying mechanism 200. The input pipe 120 and the output pipe 110 are respectively connected to the two ends of the conveying mechanism 200. The end of the input pipe 120 away from the conveying mechanism 200 is the input end of the conical object, and the end of the conveying mechanism 200 is connected to the output pipe 110. The output pipe 110 is the end point for conveying the conical object.

[0032] The conveying mechanism 200 includes a first tee 220, a second gate 350, a buffer pipe 210, a gripper 340, a storage pipe 250, a fourth gate 330, and a second tee 230. The input pipe 120, the first tee 220, the second gate 350, the buffer pipe 210, the gripper 340, the storage pipe 250, the fourth gate 330, the second tee 230, and the output pipe 110 are connected in series.

[0033] A second gate 350, a buffer pipe 210, a gripper 340, a storage pipe 250, and a fourth gate 330 are provided between the first tee 220 and the second tee 230. The conveying mechanism 200 also includes a support column 201 and a pallet 202. The pallet 202 is located in the middle section of the support column 201, and the fourth gate 330 is mounted on the pallet 202. The second gate 350 is located at the top of the support column 201. The conveying mechanism 200 uses the support column 201 and the pallet 202 to provide support. The fourth gate 330 is connected to the side of the storage pipe 250 away from the first tee 220.

[0034] Initially, the fourth gate 330 is closed. The conical object input from the input pipe 120 falls into the storage pipe 250 and is blocked by the fourth gate 330. As the conical object fills the storage pipe 250, the gripper unit 340 is activated to clamp and block the conical object subsequently fed into the buffer pipe 210. The conical object in the storage pipe 250 will enter the second tee 230 under its own weight after the fourth gate 330 is opened. As the conical object in the storage pipe 250 leaves, the fourth gate 330 will close in time, and the third gate 320 will open. The above operation is repeated.

[0035] The device for conveying a conical object by airflow also includes an exhaust fan and a blower. The exhaust fan and blower form an airflow inside the pipe to move the conical object. The connection port on the side wall of the first tee 220 is connected to the exhaust fan, and the connection port on the side wall of the second tee 230 is connected to the blower. A first gate 310 is provided at the connection port on the side wall of the first tee 220, and a third gate 320 is provided at the connection port on the side wall of the second tee 230. During the feeding and discharging process of the conical object, the fourth gate 330 and the second gate 350 will cooperate with the movement of the conical object to open and close to complete the conveying of the conical object.

[0036] Initially, the second gate 350 is closed and the first gate 310 is open. At this time, the conical object is attracted to the first tee 220 under the negative pressure of the exhaust fan. The input pipe 120 is equipped with a first sensor near the first tee 220 to detect the passage of the conical object. After the first sensor detects the object, it sends a signal to the controller, the first gate 310 closes, the second gate 350 opens, the conical object slides into the buffer tube 210, passes through the gripper unit 340, enters the storage tube 250, and is blocked by the fourth gate 330. The second gate 350 closes after a delay, and the first gate 310 reopens. The first gate 310 and the second gate 350 repeat the operation.

[0037] After the conical object fills the storage tube 250, a fourth sensor is installed at the connection between the storage tube 250 and the gripper unit 340. This fourth sensor detects that the storage tube 250 is full. The principle here is that the light signal of the fourth sensor is blocked for a prolonged period, rather than interrupted briefly and then restored, indicating that the storage tube 250 is full. The gripper unit 340 then activates and blocks subsequent conical objects. The fourth gate 330 opens, and the third gate 320 closes. The conical object will then be affected by its own weight after the fourth gate 330 opens. The conical object enters the second three-way valve 230 and continues to slide towards the output pipe 110. A second sensor is installed at the connection between the output pipe 110 and the second three-way valve 230. When the conical object passes the second sensor, the fourth gate 330 closes and the third gate 320 opens. The blower generates airflow, which blows the conical object in the output pipe 110 forward. At the same time, the gripper unit 340 releases the obstruction of the upper buffer tube 210 from the subsequent feeding of conical objects, allowing it to fill the storage tube 250. The subsequent operation is the same as described above.

[0038] In this application, the clamp unit 340 intercepts and the fourth gate 330 blocks, switching between these states to ensure that the length of the conical objects entering the output pipe 110 remains within a certain range and is placed into the output pipe 110 at certain intervals. This prevents too many conical objects from forming long structures due to nesting, which would prevent the conical objects from passing through the subsequent curved output pipe 110 and causing blockages in the curved areas, thus hindering the smooth transport of the conical objects. Secondly, since the conical objects in the pipe cannot form long nested structures through interval operation, the subsequent output pipe 110 can be arranged as needed without designing large-arc curved areas, reducing the space occupied in the workshop.

[0039] In a preferred embodiment of this invention, the first gate 310 includes a locking seat 311, a base plate 312, a first push rod 313, and a gate plate 314. The locking seat 311 is disposed on the base plate 312, and a conveying channel is provided between the locking seat 311 and the base plate 312. The locking seat 311 is provided with a locking cavity, which communicates with the conveying channel. The gate plate 314 extends into the locking cavity from the first push rod 313 and blocks the conveying channel.

[0040] Both the locking seat 311 and the base plate 312 are provided with an external connector and a through hole. The external connector mainly helps the locking seat 311 or the base plate 312 to connect with the corresponding port. The structure of the external connector can be seen in detail. Figure 6 When connecting the outer side of the locking seat 311 to the pipeline, the existing technology of clamps and other structures are used as connecting fasteners, and the through hole in the first gate 310 serves as a channel for airflow.

[0041] The first gate 310, the second gate 350, the third gate 320 and the fourth gate 330 have the same structure. It should be noted that the conveying channels in the second gate 350 and the third gate 330 are conveying channels for conical objects.

[0042] The first tee 220 has a crossbar at its side wall connection port, which passes through the center of the connection port. The crossbar blocks the conical object and prevents it from being sucked out of the connection port during the vacuuming process of the exhaust fan. The diameter of the main pipe of the first tee 220 and the second tee 230 and the diameter of the input pipe 120 are 1.3 to 1.6 times the diameter of the large end of the conical object. Even if the conical object stands inside the first tee 220, the first tee 220 still has 40% to 50% of the passage area, allowing the external exhaust fan to continuously draw the air out of the input pipe 120. The exhaust fan and blower mentioned above are existing technology equipment.

[0043] In a preferred embodiment of this invention, the gripper unit 340 includes a gripper 341, an outer cover plate 342, and a support plate 343. The outer cover plate 342 has a U-shaped structure, and the outer cover plate 342 and the support plate 343 form an operating cavity. The gripper 341 is arranged in the operating cavity and grips the conical object passing through the operating cavity.

[0044] In this embodiment, both the outer cover plate 342 and the support plate 343 are provided with circular material inlets. The buffer tube 210 is connected to the material inlet on the outer cover plate 342. The end of the first tee 220 near the second tee 230 is connected to the end of the buffer tube 210 away from the second tee 230. The conical object falling into the input pipe 120 will pass through the outer cover plate 342, the operating cavity and the support plate 343 in sequence. The material inlets on the outer cover plate 342 and the support plate 343 serve as channels for the conical object to pass through.

[0045] The gripper 341 adopts a gripper structure of existing technology. Here, the gripper 341 is mainly used to clamp the conical object. The conical object has a thin wall and will be blocked by the clamping force after being subjected to the clamping force, and will not be able to continue to slide down under its own weight. The conical object that is not subjected to the clamping force will slide into the second three-way 230 as the fourth gate 330 opens. The height distance between the fourth gate 330 and the gripper 341 can accommodate two conical objects facing opposite directions, or three conical objects with their small ends facing upwards at the same time, or four conical objects with their small ends facing downwards at the same time. By limiting the number of conical objects that can pass through the pipe at one time, blockage in the bend area can be avoided.

[0046] As a preferred embodiment of this invention, the conveying mechanism 200 further includes a main controller, and a third sensor is provided in the curved area of ​​the output pipe 110. The third sensor is used to sense the distance between the conical object and the subsequent conical object in the output pipe 110, and to sense whether the two sets of conical objects are nested.

[0047] The main controller is electrically connected to the first sensor, the second sensor, the third sensor, and the fourth sensor, as well as the first gate 310, the second gate 350, the third gate 320, the fourth gate 330, and the gripper unit 340.

[0048] In this embodiment, the first sensor, the second sensor, the third sensor and the fourth sensor are all photoelectric through-beam sensors. One side of the photoelectric through-beam sensor is a laser emitter and the other side is a laser receiver. When a conical object is present between the emitter and the receiver, the laser beam is cut off, which causes the laser receiver to send a signal to the controller.

[0049] When the laser signal of the first sensor is cut off, it indicates that a conical object has passed through the input pipe 120. The main controller closes the first gate 310 to disconnect the external exhaust fan from the conveying mechanism 200, and at the same time opens the second gate 350. The conical object passing between the first sensor and the first three-way 220 slides down under its own weight, passes through the second gate 350 and reaches the buffer pipe 210.

[0050] The fact that the light signal of the fourth sensor was cut off for a long time indicates that the conical object inside the storage tube 250 has been stacked to a certain height, making it impossible for the light signal of the fourth sensor to be restored. Normally, the passage of the conical object will only cause the light signal of the fourth sensor to be interrupted for a short time, and it will be restored immediately after the conical object passes through.

[0051] The main controller identifies whether the conical object has filled the storage tube 250 based on the feedback information from the optical signal of the fourth sensor. When the storage tube 250 is full, the gripper unit 340 is activated and blocks the subsequent conical objects. The fourth gate 330 is opened and the third gate 320 is closed. After the fourth gate 330 is opened, the conical object will enter the second tee 230 under its own weight and continue to slide towards the output pipe 110.

[0052] When the conical object passes the second sensor, it indicates that the conical object has completely left the second three-way 230. The main controller closes the fourth gate 330 and opens the third gate 320 to reconnect the external blower. The external blower blows air into the output pipe 110. The airflow from the external blower will exist in the output pipe 110 and be output along the output pipe 110 to the end of the output pipe 110.
