Description

Technical Field

[0001] The present invention belongs to the technical field of conical object transportation, and particularly relates to a device for transporting conical objects by air flow. Background Art

[0002] In the textile industry, thin-walled and lightweight conical paper yarn tubes formed of paper are used for the yarn delivered by spinning mills, and thin-walled and lightweight conical rubber cores formed by injection molding are widely used for the finished pagoda yarns in the textile thread manufacturing industry. These conical-structured objects (hereinafter referred to as conical objects) need to be sent to a designated area by means of corresponding air flow transportation equipment during the process of putting, collecting and processing.

[0003] In the prior art, most of the conical objects are transported by pipeline transportation. However, these conical objects are prone to nesting with each other. When transported through the pipeline, the conical objects are easily nested into a long strip structure. These nested conical objects with too long length will be blocked and unable to pass through in the bending area of the pipeline, resulting in the situation that the conical objects cannot be transported normally. Summary of the Invention

[0004] The present invention provides a device for transporting conical objects by air flow, aiming to solve the problem that the conical objects cannot be transported normally because the nested conical objects are blocked and unable to pass through in the bending area of the pipeline due to their too long structure.

After the conical object passes through the second sensor, the fourth gate closes, the third gate opens, and the air flow generated by the blower enters the output pipe through the third gate and then pushes the conical object to move.

The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0029] An embodiment of the present invention provides a device for pneumatically conveying conical objects, such as Figures 1-7 shown, the device for pneumatically conveying conical objects includes:

[0030] 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 both ends of the conveying mechanism 200. One end of the input pipe 120 far from the conveying mechanism 200 is the input end of the conical object. The end of the conveying mechanism 200 is connected to the output pipe 110. The output pipe 110 is the conveying end of the conical object.

[0031] The conveying mechanism 200 includes a first three-way joint 220, a second gate 350, a buffer pipe 210, a clamping jaw 340, a storage pipe 250, a fourth gate 330, and a second three-way joint 230. The input pipe 120, the first three-way joint 220, the second gate 350, the buffer pipe 210, the clamping jaw 340, the storage pipe 250, the fourth gate 330, the second three-way joint 230, and the output pipe 110 are connected in series in sequence.

[0032] A second gate 350, a buffer pipe 210, a clamping jaw 340, a storage pipe 250, and a fourth gate 330 are provided between the first three-way joint 220 and the second three-way joint 230. The conveying mechanism 200 further includes a support column 201 and a support plate 202. The support plate 202 is disposed in the middle section of the support column 201. The fourth gate 330 is assembled on the support plate 202. The second gate 350 is disposed at the top of the support column 201. The conveying mechanism 200 provides a supporting function by means of the support column 201 and the support plate 202. The fourth gate 330 is connected to the side of the storage pipe 250 far from the first three-way joint 220.

[0033] In the initial state, the fourth gate 330 is in the closed state. The conical objects input through the input pipe 120 will be blocked by the fourth gate 330 when they fall into the storage pipe 250. After the storage pipe 250 is filled with conical objects, the gripper unit 340 is activated to clamp and block the subsequent conical objects sent into the buffer pipe 210. The conical objects located in the storage pipe 250 will enter the second three-way pipe 230 under the action of their own weight after the fourth gate 330 is opened. As the conical objects in the storage pipe 250 leave the fourth gate 330, it will be closed in time, and the third gate 320 is opened, repeating the above operations;

[0034] The device for pneumatically conveying conical objects further includes a suction fan and a blower. The suction fan and the blower form an air flow for moving the conical objects inside the pipe. The connection port provided on the side wall of the first three-way pipe 220 is connected to the suction fan, and the connection port provided on the side wall of the second three-way pipe 230 is connected to the blower. A first gate 310 is provided at the connection port on the side wall of the first three-way pipe 220, and a third gate 320 is provided at the connection port on the side wall of the second three-way pipe 230. During the feeding and discharging process of the conical objects, the fourth gate 330 and the second gate 350 will cooperate with the movement of the conical objects to perform opening and closing operations to complete the conveying of the conical objects;

[0035] The sensing assembly, the sensing assembly includes a first sensor provided at one end of the input pipe 120 close to the first three-way pipe 220, a second sensor provided at the connection between the output pipe 110 and the second three-way pipe 230, and a fourth sensor provided at the connection between the storage pipe 250 and the gripper unit 340;

[0036] In the initial state, the second gate 350 is in the closed state, and the first gate 310 is in the open state. At this time, the conical objects will be adsorbed to the first three-way pipe 220 under the negative pressure of the suction fan. Here, the first sensor is used to sense the passing of the conical objects; after the first sensor senses, it gives a signal to the controller, the first gate 310 is closed, the second gate 350 is opened, the conical objects slide into the buffer pipe 210, pass through the gripper unit 340 and enter the storage pipe 250, and are blocked by the fourth gate 330. The second gate 350 closes with a delay, and the first gate 310 is opened again; the first gate 310 and the second gate 350 repeat the actions.

[0037] After the conical object fills the storage pipe 250, the fourth sensor is used to sense that the conical object fills the storage pipe 250. The principle here is that the optical signal of the fourth sensor is blocked for a long time instead of being interrupted and then restored in a short time, indicating that the conical object fills the storage pipe 250. The jaw unit 340 is activated to block the subsequent conical objects. The fourth gate 330 is opened, and the third gate 320 is closed. The conical object will enter the second tee 230 under its own weight after the fourth gate 330 is opened and continue to slide towards the output pipe 110. The second sensor is arranged at the connection between the output pipe 110 and the second tee 230 to sense whether the conical object leaves the second tee 230. When the conical object passes through the second sensor, the fourth gate 330 is closed, and the third gate 320 is opened. The air flow generated by the blower will blow the conical object located in the output pipe 110 to continue moving forward. At the same time, the jaw unit 340 releases the block on the subsequent conical object fed into the upper buffer pipe 210 to fill the storage pipe 250. Subsequently, the operations described above are repeated;

[0038] In this application, by switching between the interception of the jaw unit 340 and the blocking state of the fourth gate 330, it is ensured that the length of the conical object entering the output pipe 110 is maintained within a corresponding range and is put into the output pipe 110 at a certain interval. Cooperating with the sensing of the state of the conical object entering the output pipe by the sensing component, the length of the conical object is maintained within a corresponding range, avoiding that too many conical objects form a long structure due to nesting during the pipeline travel, resulting in the conical object being unable to pass through the subsequent curved output pipe 110 and causing blockage of the output pipe 110 in the curved area and poor conveyance of the conical object; secondly, since the conical objects in the pipeline cannot form a long nested structure through interval operations, the subsequent output pipe 110 can be arranged as needed without being designed into a large-curvature curved area, reducing the occupation of space in the workshop.

[0039] As a preferred implementation manner in this embodiment, the first gate 310 includes a locking seat 311, a substrate 312, a first push rod 313 and a gate plate 314. The locking seat 311 is arranged on the substrate 312. A conveying channel is provided between the locking seat 311 and the substrate 312. A locking cavity is provided on the locking seat 311, and the locking cavity communicates with the conveying channel. The gate plate 314 blocks the conveying channel when the first push rod 313 extends into the locking cavity;

[0040] Both the locking seat 311 and the substrate 312 are provided with external connecting pipes and through holes. The external connecting pipes mainly help the locking seat 311 or the substrate 312 to be connected to the corresponding pipe orifice. For the structure of the external connecting pipes, please refer to Figure 6Outside the middle locking seat 311, when connecting to the pipeline, structures such as clamps in the prior art are used as connection and fixing parts, and the through hole in the first gate 310 serves as the air flow channel;

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

[0042] A crossbar is provided at the connection port on the side wall of the first tee 220. The crossbar passes through the center of the connection port. The crossbar blocks the conical object to prevent the conical object from being sucked out of the connection port during the vacuum pumping process by the exhaust fan. The diameters of the main pipes of the first tee 220 and the second tee 230 and the diameter of the input pipeline 120 are 1.3 - 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 a passing area of 40% - 50%, allowing the external exhaust fan to continuously suck out the air in the input pipeline 120. The exhaust fan and the blower mentioned above are both equipment in the prior art.

[0043] As a preferred implementation mode in this embodiment, the jaw unit 340 includes jaws 341, an outer cover plate 342, and a support plate 343. The outer cover plate 342 is of a U-shaped structure. The outer cover plate 342 and the support plate 343 form an operation cavity. The jaws 341 are arranged in the operation cavity, and the jaws 341 clamp the conical object passing through the operation cavity;

[0044] In this embodiment, circular material ports are provided on both the outer cover plate 342 and the support plate 343. The buffer pipe 210 communicates with the material port on the outer cover plate 342. One end of the first tee 220 close to the second tee 230 communicates with the port at the end of the buffer pipe 210 far from the second tee 230; The conical objects falling in the input pipeline 120 will sequentially pass through the outer cover plate 342, the operation cavity, and the support plate 343. The material ports on the outer cover plate 342 and the support plate 343 serve as the channels for the conical objects to pass through.

[0045] The jaws 341 adopt the jaw structure in the prior art. Here, the jaws 341 mainly clamp the conical object. After the clamping force is applied to the thin-walled conical object, it will be blocked and unable to continue sliding under its own weight, while the conical object not subjected to the clamping force will slide into the second tee 230 as the fourth gate 330 opens. The height distance between the fourth gate 330 and the jaws 341 can accommodate 2 conical objects with opposite facing directions or 3 conical objects with small ends facing the sky simultaneously or 4 conical objects with small ends facing the ground simultaneously; By restricting the number of conical objects passing through the pipeline at a single time, the situation of blockage in the bend area can be avoided;

[0046] As a preferred implementation manner in this embodiment, the conveying mechanism 200 further includes a main controller. A third sensor is provided in the bending area of the output pipe 110. The third sensor is used to sense the distance between the conical object in the output pipe 110 and the subsequent conical object, so as to avoid the situation where two sets of conical objects are nested front and back.

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

[0048] In this embodiment, the first sensor, the second sensor, the third sensor and the fourth sensor are all photoelectric opposed sensors. One side of the photoelectric opposed sensor is a laser emitter and the other side is a laser receiver. When a conical object exists between the emitter and the receiver, the laser beam is cut off to prompt 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 tee 220 slides down under its own weight and passes through the second gate 350 to reach the buffer pipe 210;

[0050] If the optical signal of the fourth sensor is cut off for a long time, it means that the conical objects in the storage pipe 250 have been stacked to a certain height, completely preventing the optical signal of the fourth sensor from being restored. The passing of a normal conical object will only cause the optical signal of the fourth sensor to be interrupted for a short time, and the optical signal will be restored immediately after the conical object passes;

[0051] The main controller identifies whether the storage pipe 250 is filled with conical objects according to the feedback information of the optical signal of the fourth sensor. When the storage pipe 250 is filled, the jaw unit 340 is activated to block the subsequent conical objects. The fourth gate 330 is opened and the third gate 320 is closed. The conical object will enter the second tee 230 under its own weight after the fourth gate 330 is opened and continue to slide towards the output pipe 110;

[0052] When the conical object passes through the second sensor, it means that the conical object has completely left the second tee 230. The main controller closes the fourth gate 330 and opens the third gate 320 to reconnect to the external blower again. The third gate 320 is opened to connect to the external blower to blow air into the output pipe 110. The air flow of the external blower will output the air existing in the output pipe 110 along the output pipe 110 to the end of the output pipe 110.
