Description

Technical Field

[0001] This invention relates to the technical field of threading board processing, and particularly to an automatic pin insertion machine for threading boards. Background Technology

[0002] When a computerized flat knitting machine is knitting, a raising device is needed to pull and raise the fabric. The raising device includes a threading plate and a wire conveying assembly, with raising needles mounted on the threading plate. The wire conveying assembly drives the wire to move, and the wire passes through the raising needles. After the first row is knitted, the pressure rollers within the wire conveying assembly begin to push the wire until it passes through the raising needle. Then, the raising device descends, and the threading plate pulls the fabric evenly, completing the raising process.

[0003] In related technologies, positioning pins need to be installed on the threading plate before installation. The common practice in these solutions is to manually tighten multiple pins one by one into the pin holes on the threading plate to assemble the threading plate and pins, facilitating subsequent connection of the threading plate to other components in the lifting device.

[0004] In the aforementioned related technologies, manually assembling pins on the threading board requires loading, assembling, and unloading the threading board and pins, which is labor-intensive, has low processing efficiency, and is not suitable for the needs of large-scale production. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic pin insertion machine for threading boards, which can realize the automatic assembly of threading board pins and improve the processing efficiency of threading boards.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0007] This invention provides an automatic pin insertion machine for a threading board, the automatic pin insertion machine comprising:

[0008] frame;

[0009] A pin feeding mechanism includes a vibratory feeder and a feeding tube. The vibratory feeder is mounted on the frame, and the feeding tube is connected to the vibratory feeder. The vibratory feeder is used to feed the loaded pins into the feeding tube. The feeding tube has an opening facing downwards at one end away from the vibratory feeder.

[0010] The loading mechanism includes a material support, a pin, and a lifting assembly. The material support is disposed on the frame and has an assembly hole adapted to the pin. The pin is directly opposite the assembly hole and is adapted to the assembly hole. The lifting assembly can drive the pin to move vertically up and down.

[0011] A pin transfer mechanism is provided on the frame and moves between the lower end of the feeding tube and the material receiving seat. The pin transfer mechanism is capable of gripping and releasing the pin.

[0012] The upper plate mechanism is used to clamp and fix the threading plate. The threading plate has a pin hole. The upper plate mechanism can clamp the threading plate and move it to a position where the pin hole is directly below the assembly hole.

[0013] Furthermore, the pin transfer mechanism includes a pneumatic gripper, a transfer track, a transfer seat, and a transfer cylinder. The transfer track is fixedly mounted on the frame, the transfer seat is slidably fitted onto the transfer track, the pneumatic gripper is fixedly connected to the transfer seat, and the transfer cylinder is connected to the transfer seat to drive the pneumatic gripper to move between the lower end of the feeding tube and the assembly hole.

[0014] Furthermore, the frame is provided with a pin support facing the lower end of the feeding tube; a clamping hole is formed between the two jaws of the pneumatic gripper, and the jaws of the pneumatic gripper can move onto the pin support so that the clamping hole faces the lower end of the feeding tube.

[0015] Furthermore, the frame is provided with a pipe end clamping mechanism, the position of which can be adjusted relative to the frame in the up and down, left and right, and front and back directions, and the lower end of the feeding pipe is fixedly connected to the pipe end clamping mechanism.

[0016] Furthermore, the automatic pin-insertion machine also includes a feeding control mechanism, which includes a control cylinder and a control push rod. The control push rod is connected to the piston rod of the control cylinder. A control groove is provided at the lower end of the feeding tube. The control groove is connected to the inner cavity of the feeding tube. The piston rod can drive the control push rod to insert into the control groove and abut against the pin inside the feeding tube.

[0017] Furthermore, the feeding pipe includes a first pipe section and a second pipe section. The first pipe section is fixedly mounted on the frame by the pipe end clamping mechanism, and the second pipe section is connected between the first pipe section and the vibratory plate. The first pipe section is a rigid pipe, the second pipe section is a flexible pipe, and the first pipe section and the second pipe section are detachably connected.

[0018] Furthermore, the first pipe section is provided with a stress groove, which is connected to the inner cavity of the first pipe section and extends along the axial direction of the first pipe section.

[0019] Furthermore, the upper plate mechanism includes a first clamping component, a first horizontal driving component, and a first vertical driving component. The first clamping component is connected to the first vertical driving component, and the first vertical driving component is connected to the first horizontal driving component. The first horizontal driving component is used to drive the first vertical driving component and the first clamping component to move horizontally, the first vertical driving component is used to drive the first clamping component to move vertically, and the first clamping component is used to clamp the threading plate.

[0020] Furthermore, the automatic pin insertion machine also includes a lower plate mechanism, which is disposed on the side of the loading mechanism opposite to the upper plate mechanism;

[0021] The lower plate mechanism includes a second clamping component, a second horizontal driving component, and a second vertical driving component. The second clamping component is connected to the second vertical driving component, and the second vertical driving component is connected to the second horizontal driving component. The second horizontal driving component is used to drive the second vertical driving component and the second clamping component to move horizontally, and the second vertical driving component is used to drive the second clamping component to move vertically. The second clamping component is used to clamp the threading plate.

[0022] Furthermore, the automatic pin insertion machine also includes a pressure plate mechanism, which is vertically and flexibly mounted on the frame and is used to press the threading plate onto the frame.

[0023] In summary, the present invention has the following beneficial effects:

[0024] 1. In this invention, the threading plate is clamped and fixed on the frame by the upper plate mechanism. The upper plate mechanism moves the threading plate to below the material support, so that the pin hole on the threading plate is aligned with the assembly hole on the material support. The vibratory feeder of the pin feeding mechanism loads the pins, and the vibratory feeder vibrates and transports the pins, so that the pins move along the feeding tube. The pin transfer mechanism picks up the pins from the lower end of the feeding tube and moves them to the material support, so that the pins are aligned with the assembly hole. Then, the pin transfer mechanism releases the pins, and the pins fall into the assembly hole. The lifting component of the feeding mechanism drives the pin to descend, and the pin inserts into the assembly hole to push the pin into the pin hole of the threading plate, thereby realizing the automatic assembly of the pins on the threading plate, reducing the intensity of manual labor, and improving the assembly efficiency of the threading plate and the pins.

[0025] 2. The pin transfer mechanism drives the pneumatic gripper to move along the transfer track through the transfer cylinder, so that the pneumatic gripper can clamp the pin at the lower end of the feeding tube and transport the pin to the top of the assembly hole. The feeding tube and the loading mechanism are staggered to avoid the feeding tube interfering with the control of the lifting rod.

[0026] 3. The pin support is directly opposite the lower end of the feed tube. When removing the pin, the pneumatic gripper moves above the pin support and the two halves of the pneumatic gripper separate slightly, which increases the clamping hole. After the pin falls from the feed tube, it lands on the pin support and is located in the clamping hole. At this time, the two halves of the pneumatic gripper close to clamp the pin, which facilitates the clamping of the pin when moving it.

[0027] 4. The pipe end clamping mechanism clamps the lower end of the feeding pipe to fix the feeding pipe on the frame, so that the pin transfer mechanism can pick up the pin from the lower end of the feeding pipe. The pipe end clamping mechanism can be adjusted in position relative to the frame up and down, left and right, and front and back to better clamp the feeding pipe.

[0028] 5. The automatic pin-insertion machine also includes a feeding control mechanism. The feeding control mechanism drives the control rod to extend and retract via a control cylinder, allowing the control rod to insert into the control slot of the feeding tube and press against the pin. Thus, when the pin transfer mechanism leaves the lower end of the feeding tube, the control rod presses against the pin, preventing it from falling. When the pin transfer mechanism is facing the lower end of the feeding tube, the control cylinder controls the control rod to leave the control slot, allowing the pin in the feeding tube to leave the feeding tube and be clamped and moved by the pin transfer mechanism. Therefore, the feeding control mechanism controls the feeding rhythm of the pins in the feeding tube to meet the production cycle.

[0029] 6. The feeding pipe includes a first section and a second section. The first section is clamped and fixed to the frame by a pipe end clamping mechanism. The second section connects the vibratory feeder and the first section to transport the pins from the vibratory feeder to the first section. The first section is made of rigid tubing, which allows it to be stably fixed to the frame, facilitating the removal of the pins from their fixed position. This makes it easier for the pin transfer mechanism to clamp and transport the pins, and also facilitates the feeding control mechanism to press the pins against the first section. The second section is made of flexible tubing, which can be bent at any angle to facilitate connection between the vibratory feeder and the first section. The first and second sections are detachably connected for easy assembly and disassembly of the feeding pipe.

[0030] 7. The upper plate mechanism clamps the threading plate through the first clamping component. The first vertical drive component drives the first clamping component to lift and lower, so as to adjust the vertical position of the threading plate and avoid collision with the structure on the frame when the threading plate moves. The first horizontal drive component drives the first clamping component to clamp the threading plate horizontally, so that the threading plate moves to the bottom of the material support, and the pin hole and the assembly hole are aligned, thereby realizing the automatic feeding of the threading plate.

[0031] 8. After the pins are installed on the threading plate, the lower plate mechanism clamps the threading plate through the second clamping component. The second vertical drive component drives the second clamping component to rise and fall, and the second horizontal drive component drives the second clamping component to move the threading plate horizontally away from the material support, thereby realizing the automatic unloading of the threading plate.

[0032] 9. The pressure plate mechanism is mounted on the frame in a height-adjustable manner. The pressure plate mechanism presses the wire threading plate tightly, so that the wire threading plate is not easy to shift or shake when assembling the pins. Attached Figure Description

[0045] The invention will now be further described with reference to the accompanying drawings.

[0046] This embodiment discloses an automatic pin insertion machine 1000 for threading boards, referring to... Figure 1 The automatic pin-insertion machine 1000 includes a frame 100, a pin feeding mechanism 200, a loading mechanism 300, a pin transferring mechanism 400, and a plate-mounting mechanism 500. The pin feeding mechanism 200, the loading mechanism 300, the pin transferring mechanism 400, and the plate-mounting mechanism 500 are mounted on the frame 100.

[0047] Reference Figure 1 and Figure 2In this embodiment, the automatic pin-attaching machine 1000 is used for assembling pins on the threading plate 2000. Specifically, the threading plate 2000 is a long strip, and multiple pin holes 2100 that mate with pins are provided on the threading plate 2000. The loading mechanism 500 transports the threading plate 2000 to the loading mechanism 300 on the frame 100. The pin feeding mechanism 200 is used for automatic pin feeding. The pin transferring mechanism 400 transfers the pins transported by the pin feeding mechanism 200 to the loading mechanism 300. The loading mechanism 300 inserts the pins into the pin holes 2100 of the threading plate 2000, thereby realizing the automatic assembly of pins on the threading plate 2000.

[0048] Reference Figure 1 and Figure 3 The pin feeding mechanism 200 includes a vibratory feeder 210 and a feeding tube 220. The vibratory feeder 210 is mounted on the frame 100, and the feeding tube 220 is connected to the vibratory feeder 210. The vibratory feeder 210 contains a plurality of pins, and the vibratory feeder 210 sequentially feeds the loaded pins into the feeding tube 220.

[0049] In this embodiment, an upper support 110 is fixedly mounted on the frame 100, and a vibratory feeder 210 is fixedly mounted above the upper support 110, so that the vibratory feeder 210 is located above the frame 100. The end of the feeding pipe 220 away from the vibratory feeder 210 extends downward, and the opening of the end of the feeding pipe 220 away from the vibratory feeder 210 is set downward, so that the pin falling from the lower end of the feeding pipe 220 can be clamped by the pin transfer mechanism 400.

[0050] In this system, the vibratory feeder 210 drives multiple pins to be arranged and moved sequentially along the axial direction, and the feeding pipe 220 is connected to the discharge port of the vibratory feeder 210. The inner diameter of the feeding pipe 220 is slightly larger than the outer diameter of the pins. The pins leave the vibratory feeder 210, enter the feeding pipe 220, and move along the axial direction of the feeding pipe 220.

[0051] Reference Figure 3 and Figure 4 The feeding pipe 220 includes a first pipe section 221 and a second pipe section 222. The first pipe section 221 is vertically fixed above the frame 100, and the second pipe section 222 is connected between the first pipe section 221 and the vibratory plate 210.

[0052] In this embodiment, the second pipe segment 222 is a flexible pipe, specifically bent into a downward arc shape to facilitate the connection between the first pipe segment 221 and the vibratory feeder 210 for transmitting the pins. The first pipe segment 221 is a rigid pipe, which allows the first pipe segment 221 to be stably fixed on the frame 100, making it easier for the pins to leave the fixed position from the first pipe segment 221, thereby facilitating the pin transfer mechanism 400 to clamp and transport the pins.

[0053] In this embodiment, a support frame 600 is provided on the frame 100. The support frame 600 includes a plurality of vertically arranged columns 610 and a support plate 620 fixedly disposed above the columns 610. The support plate 620 is provided with a through hole, through which the first pipe segment 221 passes and is fixed to the support plate 620. In addition, in other embodiments, the first pipe segment 221 may also be fixed above the frame 100 in other suitable ways.

[0054] In this embodiment, the first pipe segment 221 and the second pipe segment 222 are detachably connected, facilitating the assembly and disassembly of the feeding pipe 220. Specifically, in this embodiment, the end of the second pipe segment 222 furthest from the vibratory feeder 210 is sleeved onto the upper end of the first pipe segment 221.

[0055] Reference Figure 5 In this embodiment, a long strip-shaped stress groove 223 is formed on the periphery of the first pipe segment 221. The stress groove 223 communicates with the inner cavity of the first pipe segment 221 and extends along the axial direction of the first pipe segment 221. As a result, when the pin moves in the inner cavity of the first pipe segment 221, the friction between the pin and the first pipe segment 221 can be reduced. At the same time, the first pipe segment 221 can deform and release stress near the stress groove 223, reducing the wear between the pin and the first pipe segment 221.

[0056] Reference Figures 3 to 5 A pipe end clamping mechanism 700 is provided on the frame 100. The lower end of the first pipe section 221 is fixedly connected to the pipe end clamping mechanism 700. The first pipe section 221 is fixed together by the pipe end clamping mechanism 700 and the support plate 620, so that the first pipe section 221 is installed more firmly and reliably, so as to fix the feeding pipe 220 on the frame 100, and facilitate the pin transfer mechanism 400 to clamp the pin from the lower end of the feeding pipe 220.

[0057] Reference Figure 5 and Figure 6The pipe end clamping mechanism 700 can be adjusted in position relative to the frame 100 in terms of up and down, left and right, and front and back, so as to adjust its position and better clamp the feeding pipe 220. Specifically, in this embodiment, the pipe end clamping mechanism 700 includes a first clamping arm 710 and a second clamping arm 720. One end of the first clamping arm 710 is provided with a first clamping hole 711 and a first clearance groove 712 communicating with the first clamping hole 711. The first clearance groove 712 extends through the end of the first clamping arm 710 in a direction away from the first clamping hole 711. The first clamping arm 710 is provided with two opposing first connecting holes 713 in a direction perpendicular to the first clearance groove 712. The first connecting holes 713 communicate with the first clearance groove 712. A column 610 of the support frame 600 is inserted into the first clamping hole 711. A bolt passes through the first connecting hole 713 and is locked with a nut, thereby reducing the size of the first clearance groove 712 and the first clamping hole 711. The inner wall of the first clamping hole 711 hugs the column 610, thus achieving a fixed connection of the first clamping arm 710 on the frame 100. After loosening the nut, the first clamping arm 710 can be rotated relative to the column 610 or moved vertically to adjust the position of the first clamping arm 710.

[0058] One end of the second clamping arm 720 is connected to the end of the first clamping arm 710 away from the first clamping hole 711. The end of the second clamping arm 720 away from the first clamping arm 710 has a second clamping hole 721 and a second clearance groove 722. The second clearance groove 722 extends through the end of the second clamping arm 720 in a direction away from the second clamping hole 721. The second clamping arm 720 has two opposing second connecting holes 723 in a direction perpendicular to the second clearance groove 722, and the second connecting holes 723 communicate with the second clearance groove 722. The lower end of the first pipe section 221 passes through the second clamping hole 721. A bolt passes through the second connecting hole 723 and is locked by a nut. When the nut is tightened, the end of the second clamping arm 720 deforms, causing the second clearance groove 722 and the second clamping hole 721 to shrink and grip the lower end of the first pipe section 221, thus clamping the first pipe section 221.

[0059] The first clamping arm 710 and the second clamping arm 720 are adjustablely connected. Specifically, the first clamping arm 710 has an elongated hole 714 along its extension direction, and the second clamping arm 720 has one, two, or more mounting holes 724, at least some of which are aligned with the elongated hole 714. The first clamping arm 710 and the second clamping arm 720 are fixedly connected by bolts passing through the elongated hole 714 and the mounting hole 724 and nuts that mate with the bolts. When the bolts and nuts are loosened, the second clamping arm 720 can be adjusted along the length direction of the elongated hole 714.

[0060] Reference Figure 5 and Figure 7A control groove 224 is provided at the lower end of the first pipe section 221. The control groove 224 is connected to the inner cavity of the feeding pipe 220, and the opening of the control groove 224 is connected to the space outside the first pipe section 221. A feeding control mechanism 800 is provided on the frame 100. In this embodiment, the feeding control mechanism 800 includes a control cylinder 810 and a control push rod 820. The control push rod 820 is connected to the piston rod of the control cylinder 810. A support base 120 is provided on the frame 100. The control cylinder 810 is horizontally arranged on the support base 120, so that the control push rod 820 and the control groove 224 are at the same height, so that the piston rod can drive the control push rod 820 to insert into the control groove 224 and abut against the pin in the feeding pipe 220.

[0061] When the pin transfer mechanism 400 leaves the lower end of the feeding tube 220, the control push rod 820 presses against the pin to prevent it from falling. When the pin transfer mechanism 400 is facing the lower end of the feeding tube 220, the control cylinder 810 controls the push rod 820 to leave the control groove 224, allowing the pin in the feeding tube 220 to leave the feeding tube 220 and be clamped and moved by the pin transfer mechanism 400. Thus, the feeding rhythm of the pins in the feeding tube 220 is controlled by the feeding control mechanism 800 to meet the production cycle.

[0062] The frame 100 is provided with a pin support 130 facing the lower end of the first pipe section 221 of the feed pipe 220. The pin of the first pipe section 221 rests above the pin support 130 so that the pin transfer mechanism 400 can clamp and transfer the pin.

[0063] Reference Figure 1 , Figure 5 and Figure 7 The pin transfer mechanism 400 is installed on the frame 100. The pin transfer mechanism 400 is located between the lower end of the feeding pipe 220 and the loading mechanism 300. The pin transfer mechanism 400 can clamp and release pins.

[0064] In this embodiment, the pin transfer mechanism 400 includes a pneumatic gripper 410, a transfer track 420, a transfer seat 430, and a transfer cylinder 440. The transfer track 420 is fixedly mounted on the frame 100 and extends from the lower end of the feeding pipe 220 to the loading mechanism 300. The transfer seat 430 is slidably fitted onto the transfer track 420 along its length, and the pneumatic gripper 410 is fixedly connected to the transfer seat 430. The cylinder body of the transfer cylinder 440 is fixed on the frame 100, and the piston rod of the transfer cylinder 440 is connected to the transfer seat 430 to drive the pneumatic gripper 410 to move between the lower end of the feeding pipe 220 and the assembly hole 311.

[0065] The pin transfer mechanism 400 drives the pneumatic gripper 410 to move along the transfer track 420 via the transfer cylinder 440, so that the pneumatic gripper 410 can clamp the pin at the lower end of the feeding tube 220 and transport the pin to the area above the assembly hole 311. By setting the pin transfer mechanism 400, the feeding tube 220 and the loading mechanism 300 can be staggered, avoiding interference between the feeding tube 220 and the control rod 820 lifting and lowering.

[0066] Reference Figure 7 and Figure 8 In this embodiment, the pneumatic gripper 410 includes two gripper halves that can move towards or away from each other. Each of the two gripper halves has a semi-circular groove on its facing side, forming a circular clamping hole 411 between the two gripper halves. When the pneumatic gripper 410 moves, the gripper halves can move onto the pin support 130 so that the clamping hole 411 is aligned with the lower end of the feed tube 220. When removing the pin, the pneumatic gripper 410 moves above the pin support 130, and the two halves of the pneumatic gripper 410 slightly separate, making the clamping hole 411 larger. After the pin falls from the feed tube 220, it lands on the pin support 130 and is located in the clamping hole 411. The clamping hole 411 limits the pin so that it is not easy to tip over. Then the two halves of the pneumatic gripper 410 close, making the clamping hole 411 smaller to clamp the pin, thereby facilitating the clamping of the pin when transferring it.

[0067] Reference Figure 3 and Figure 9 In this embodiment, the loading mechanism 300 includes a material support 310, a pin 320, and a lifting assembly 330. The material support 310 is disposed above the frame 100 and has an assembly hole 311 adapted to the pin, which extends through the upper and lower sides of the material support 310. The pin 320 is directly opposite to and adapted to the assembly hole 311. The lifting assembly 330 can drive the pin 320 to move vertically up and down so that the pin 320 is vertically inserted into or disengaged from the assembly hole 311.

[0068] When the automatic pin-fitting machine 1000 assembles pins on the threading plate 2000, the threading plate 2000 is clamped and fixed on the frame 100 by the upper plate mechanism 500. The upper plate mechanism 500 moves the threading plate 2000 to below the material support 310, so that the pin hole 2100 on the threading plate 2000 is aligned with the assembly hole 311 on the material support 310. The vibratory feeder 210 of the pin feeding mechanism 200 loads the pins. The vibratory feeder 210 vibrates and conveys the pins, causing the pins to move along the feeding pipe 220. The pins fall from the lower end of the first section 221 of the feeding pipe 220 onto the pin support 130 and are confined in the clamping hole 411 of the pneumatic gripper 410. After the pneumatic gripper 410 clamps the pins, it moves along the material transfer track 420 to above the material support 310, so that the pins are aligned with the assembly hole 311. Then the pins are released and fall into the assembly hole 311. After the material transfer cylinder 440 drives the pneumatic gripper 410 to move away from the material support 310, the lifting component 330 of the loading mechanism 300 drives the pin 320 to descend. The pin 320 inserts into the assembly hole 311 and pushes the pin into the pin hole 2100 of the wire threading plate 2000, thereby realizing the automatic assembly of the pin on the wire threading plate 2000, reducing the intensity of manual labor, and improving the assembly efficiency of the wire threading plate 2000 and the pin.

[0069] In this embodiment, the lifting assembly 330 specifically includes a vertically arranged cylinder. The cylinder body is fixed on the support plate 620, and the piston rod of the cylinder extends vertically downward and is fixedly connected to the pin 320.

[0070] In this embodiment, two pins 320 are provided, and correspondingly two assembly holes 311, two pin feeding mechanisms 200, and two pin transferring mechanisms 400 are provided, so that two pins can be assembled simultaneously, thereby improving processing efficiency.

The cylinder body of the lifting and adjusting cylinder 340 is fixed on the frame 100, and the piston rod of the lifting and adjusting cylinder 340 is connected to the material support 310. When the upper plate mechanism 500 clamps and moves the threading plate 2000, the lifting and adjusting cylinder 340 drives the material support 310 to move upward to avoid interference between the threading plate 2000 and the material support 310. After the threading plate 2000 is placed, the lifting and adjusting cylinder 340 drives the material support 310 to move downward, so that the mounting hole 311 on the material support 310 is aligned and connected with the pin hole 2100 of the threading plate 2000.
