Detailed implementation manners

[0029] The following details the embodiments of the present utility model. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.

[0030] In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "linkage", "fixation", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] As Figures 1 - 9 shown, a sheathing threading and loading mechanism includes a conveying assembly 2. A vibrating bowl 1 is provided at the inlet end of the conveying assembly 2. The discharge port 101 of the vibrating bowl 1 is connected to the inlet end 210 of the conveying assembly 2. A moving assembly 3 is provided above the conveying assembly 2. The moving assembly 3 is connected with a clamping jaw 6. A storage assembly 4 is provided at the outlet end 211 of the conveying assembly 2. A supporting assembly 5 is provided beside the storage assembly 4.

[0032] Specifically, as Figure 3 、 Figure 4 and Figure 6 shown, one end of the conveying assembly 2 is the outlet end, and the other end is the inlet end. The vibrating bowl 1 serves as the feeding mechanism of the conveying assembly 2. The sheathing 7 enters the inlet end of the conveying assembly 2 from the discharge port of the vibrating bowl 1. The conveying assembly 2 conveys the sheathing 7. The clamping jaw 6 is arranged on the moving assembly 3. The moving assembly 3 drives the clamping jaw 6 to move to grab the sheathing 7 on the conveying assembly 2 and place the grabbed sheathing 7 into the storage assembly 4. Due to the conveying of the conveying assembly 2 for the material, i.e., the sheathing 7, the discharge port of the vibrating bowl 1 is dredged, avoiding the defect that the equipment stops due to a large amount of material accumulation and jamming at the discharge port of the vibrating bowl 1, and improving the production efficiency.

[0033] Furthermore, as Figure 5 and Figure 6 shown, the conveying assembly 2 includes a conveyor belt 201 and a sensor 202. The conveyor belt 201 is driven by a motor 203. A first baffle 204 and a second baffle 205 are provided above the conveyor belt 201. A conveying channel is formed between the first baffle 204 and the second baffle 205. The sensor 202 is installed above the first baffle 204 or the second baffle 205 through a sensor bracket 206.

[0034] It is understandable that the conveyor belt 201 is used to convey the sheaths 7 coming out of the vibrating bowl 1. The first baffle 204 and the second baffle 205 play a role in limiting the position. The sheath 7 comes out of the vibrating bowl 1 and enters the conveying channel between the first baffle 204 and the second baffle 205. During the process of the sheath 7 being transported and moving on the conveyor belt 201, some sheaths 7 stand upright and some are placed lying down. The sensor 202 detects in real time. Specifically, the sensor 202 can be a photoelectric switch. The photoelectric switch detects the standing sheaths 7, while the inverted sheaths 7 cannot be detected by the photoelectric switch due to insufficient height. When the photoelectric switch detects the standing sheath 7, the moving assembly 3 equipped with the clamping jaw 6 acts, and controls the clamping jaw 6 to grab the standing sheath 7.

[0035] As Figure 5 and Figure 6 shown, there are two first baffles 204 and two second baffles 205, forming two conveying channels, which can convey two groups of sheaths 7 simultaneously. At the same time, there are two sensors 202 and two sensor brackets 206, each detecting the sheaths 7 in one conveying channel.

[0036] It is understandable that the conveyor belt 201 is driven by the motor 203. The structure of driving the conveyor belt 201 by the motor 203 belongs to the existing mature technology, and the present utility model will not elaborate on this.

[0037] As Figure 5 and Figure 6 shown, the conveying assembly 2 further includes a support frame, and the support frame plays a role in supporting the motor 203 and the conveyor belt 201. Specifically, the support frame includes an upper support plate 207, a lower support plate 208 and a plurality of support columns 209. The plurality of support columns 209 are arranged between the upper support plate 207 and the lower support plate 208 and connect the upper support plate 207 and the lower support plate 208.

[0038] Furthermore, as Figure 1 shown, the moving assembly 3 includes a first electric cylinder 301. The first electric cylinder 301 is horizontally arranged above the conveying assembly 2, and the first electric cylinder 301 is parallel to the conveyor belt 201. The first electric cylinder 301 is connected with a moving plate 306, and the moving plate 306 is connected with a first cylinder mounting plate 302. The moving plate 306 can move along the direction of the first electric cylinder 301

[0039] Furthermore, as Figure 8 shown, the first cylinder mounting plate 302 is provided with a lifting cylinder 303. The lifting cylinder 303 is connected with a second cylinder mounting plate 304. The second cylinder mounting plate 304 is provided with a clamping jaw driving cylinder 305, and the clamping jaw driving cylinder 305 is connected with the clamping jaw 6.

[0040] As Figure 1 、Figure 7 and Figure 8 As shown in Figure 8 , there are two first cylinders, and the two first cylinders are arranged in parallel at the same height. At the same time, there are two first cylinder mounting plates 302, lifting cylinders 303, second cylinder mounting plates 304, jaw driving cylinders 305, moving plates 306 and jaws 6. That is, the moving assembly 3 and the jaws 6 can simultaneously grasp and move two groups of sheaths 7, significantly improving the working efficiency.

[0041] Specifically, the first electric cylinder 301 is supported and fixed by a support beam 307. One end of the support beam 307 is connected to the first electric cylinder 301, and the other end of the support beam 307 is fixed on the bottom plate 8.

[0042] When the sensor 202 detects the standing sheath 7, the moving plate 306 moves under the drive of the first electric cylinder 301 and comes above the sheath 7. The lifting cylinder 303 operates to place the second cylinder mounting plate 304, the jaw driving cylinder 305 and the jaws 6 downward. After reaching the appropriate height for grasping, the jaw driving cylinder 305 operates to drive the jaws 6 to grasp the standing sheath 7.

[0043] As an implementation method, when the sensor 202 detects the sheath 7, the conveyor belt 201 immediately stops rotating, and the first electric cylinder 301 translates the jaws 6 directly above the sheath 7 to clamp the sheath 7.

[0044] As an implementation method, when the sensor 202 detects the sheath 7, the conveyor belt 201 runs for a few seconds to convey the sheath 7 to the designated position and then stops rotating. The first electric cylinder 301 translates the jaws 6 directly above the sheath 7 to clamp the sheath 7.

[0045] As another implementation method, when the sensor 202 detects the sheath 7, the conveyor belt 201 continues to move. The first electric cylinder 301 translates the jaws 6 directly above the sheath 7. During the grasping process, the first electric cylinder 301 drives the jaws 6 to move together with the sheath 7, and the jaws 6 are relatively stationary with respect to the sheath 7.

[0046] Furthermore, as Figure 9 shown, the stock storage assembly 4 includes a number of stock storage pins 401 and a number of pin bases 402. The stock storage pins 401 are arranged on the rotating plate 403 through the pin bases 402, and the rotating plate 403 is connected to a rotating cylinder 404.

[0047] The stock storage pins 401 are used to place the inserted sheaths 7. Specifically, there are four stock storage pins 401. As Figure 9 shown, one of the stock storage pins 401 does not have a sheath 7 placed on it, and several sheaths 7 are inserted on the other three stock storage pins 401, so that the sheaths 7 are stacked and arranged together.

[0048] After the gripper 6 grabs the standing sheath 7, the first electric cylinder 301 drives the moving plate 306 to move, moving the sheath 7 above the stockpiling needle 401. The gripper 6 releases the sheath 7, allowing it to fall naturally until the stockpiling needle 401 fills up with the sheath 7 or enough sheaths 7 are threaded onto the stockpiling needle 401. Then, the rotary cylinder 404 drives the rotary plate 403 to rotate, switching to other stockpiling needles 401 to thread the sheaths 7.

[0049] As an implementation, as Figure 9 shown, there are four stockpiling needles 401 and needle seats 402 each. The rotary plate 403 is rectangular, and the four stockpiling needles 401 are arranged at the four top corners of the rectangular rotary plate 403 through the needle seats 402.

[0050] As an implementation, there are six stockpiling needles 401 and needle seats 402 each. The rotary plate 403 is regular hexagon-shaped, and the six stockpiling needles 401 are arranged at the six top corners of the regular hexagon-shaped rotary plate 403 through the needle seats 402.

[0051] That is to say, the number of the stockpiling needles 401 and the needle seats 402 and the shape of the rotary plate 403 are not fixed. Those skilled in the art can set them as needed. The present utility model does not specifically limit the number of the stockpiling needles 401 and the needle seats 402 and the shape of the rotary plate 403. Any number of the stockpiling needles 401 and the needle seats 402 and the shape of the rotary plate 403 that can cooperate with the conveying component 2 and the moving component 3 to thread the sheaths 7 are within the protection scope of the present utility model.

[0052] Furthermore, as Figure 9 shown, the material supporting component 5 includes a second electric cylinder 501. The second electric cylinder 501 is vertically arranged and parallel to the stockpiling needle 401. The second electric cylinder 501 is connected with a lifting plate 502. The lifting plate 502 is connected with a third cylinder mounting plate 503. The third cylinder mounting plate 503 is connected with a material supporting cylinder 504. The material supporting cylinder 504 is connected with a material supporting plate 505.

[0053] After the stockpiling needle 401 fills up with the sheath 7 or enough sheaths 7 are threaded onto the stockpiling needle 401, the second electric cylinder 501 of the material supporting component 5 drives the lifting plate 502 to move to a fixed position. The material supporting cylinder 504 acts to extend the material supporting plate 505 to lift the stacked loose sheaths on the stockpiling needle 401 to the topmost position, and then send them to the next working station for processing.

[0054] Furthermore, as Figure 1 、 Figure 2 and Figure 9 shown, the mechanism further includes a bottom plate 8. The conveying component 2, the moving component 3, the stockpiling component 4 and the material supporting component 5 are all arranged on the bottom plate 8.

[0055] Further, the mechanism further includes a feeding device 9, which is arranged on one side of the vibrating bowl 1. The feeding device 9 is used to supply supplementary materials, i.e., the sheaths 7, to the vibrating bowl 1.

[0056] Further, the mechanism further includes a recycling component, which includes a return belt 10. One end of the return belt 10 is connected to the vibrating bowl 1, and the other end of the return belt 10 is connected to the outlet end of the conveying component 2.

[0057] It can be understood that the sensor 202 only realizes the detection and identification of the standing sheaths 7 on the conveyor belt 201, and the clamping jaws 6 only grab the standing sheaths 7 detected and identified by the sensor 202, while the inverted sheaths 7 on the conveyor belt 201 are transported to the outlet end of the conveying component 2 along with the transportation of the conveyor belt 201.

[0058] As an implementation manner, the outlet end of the conveying component 2 is connected to the return belt 10. For example, a conveying pipeline can be arranged at the outlet end of the conveying component 2. The inverted sheaths 7 on the conveyor belt 201 fall from the outlet end of the conveying component 2 into the conveying pipeline and reach the other end of the return belt 10 along the pipeline. The sheaths 7 are sent back into the vibrating bowl 1 via the return belt 10.

[0059] Further, the recycling component further includes a material box, which is arranged directly below the outlet end of the conveying component 2.

[0060] As an implementation manner, a box can also be placed below the outlet end of the conveying component 2. The inverted sheaths 7 on the conveyor belt 201 fall into the box from the outlet end of the conveying component 2. When the number of sheaths 7 in the material box reaches a certain amount, the sheaths 7 in the box are picked up manually onto the return belt 10, and the sheaths 7 are sent back into the vibrating bowl 1 via the return belt 10.

[0061] The rotation of the conveyor belt 201 of the conveying component 2 drives the sheath 7 to move forward. When the sensor 202 detects the sheath 7, the conveyor belt 201 stops rotating. The first electric cylinder 301 first translates the clamping jaws 6 directly above the sheath 7. After the lifting cylinder 303 descends, the clamping jaws 6 close. After the clamping jaws 6 close, the lifting cylinder 303 operates to lift the clamping jaws 6. Then, the first electric cylinder 301 drives the clamping jaws 6 with the sheath 7 to translate directly above the stockpiling needle 401 of the stockpiling component 4. The lifting cylinder 303 operates to lower the clamping jaws 6, and the clamping jaws 6 open. At this time, the sheath 7 naturally falls along the needle body of the stockpiling needle 401 until the stockpiling needle seat is filled with the sheath 7. After the stockpiling needle 401 is filled with the sheath 7, the rotating cylinder 404 drives the rotating plate 403 to rotate 180 degrees, and the sheath 7 is inserted by the stockpiling needle 401 on the other side. The supporting cylinder 504 extends, and the second electric cylinder 501 drives the supporting plate 505 to move upward until the supporting component 5 lifts the supporting plate 505 to the top of the stockpiling needle seat. The threading and feeding of the sheath 7 are completed.

[0062] A sheathing threading and feeding mechanism of the present utility model. The sheathing enters the inlet end of the conveying assembly from the outlet end of the vibrating bowl. The conveying assembly conveys the sheathing. The clamping jaws are arranged on the moving assembly. The moving assembly drives the clamping jaws to move to grasp and thread the sheathing standing on the conveying assembly. The inverted sheathing is sent to the recycling assembly along the conveyor belt of the conveying assembly for recycling, avoiding the defect that materials are accumulated in large quantities at the discharge port of the vibrating bowl, resulting in jamming and equipment shutdown, and improving the production efficiency.

[0063] During the feeding process of the sheathing of the present utility model, there is no need to limit the direction of the sheathing, reducing the requirements and costs for the feeder.

[0064] In the description of this specification, the description with reference to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model.
