Description

Technical Field

[0001] The invention relates to the technical field of knitting machine equipment, and in particular to a knitting machine with the functions of automatic product stacking and rubber band bundling. Background Art

[0002] Flat knitting machines, also known as flat knitting machines for short, are a type of knitting machinery. They generally refer to flat knitting machines, that is, machines that use horizontal knitting needle beds for knitting. When the product is knitted, a common way to collect it is to open a channel on the side or bottom of the flat knitting machine. The knitted product is sent to the collection basket outside the machine through the channel, and then manually sorted, collected and packaged. In addition, the products are generally sold in bundles, so during the sorting process, the products need to be tied with rubber bands.

[0003] The rubber band bundling work of products woven by knitting machines on the market is mostly done manually. In order to reduce labor costs and improve work efficiency, additional rubber band bundling machines are now being equipped to perform product bundling work. For example, Chinese patent CN202122521567.1 discloses an automatic glove bundling machine, which is independently arranged from the knitting machine, and the automatic bundling machine only has a one-way rubber band bundling function for stacked products. The equipment occupies a large space, and the feeding and bundling efficiency of the rubber bands is low. There are still many manual operation steps involved in the middle. In addition, the rubber band feeding process is cumbersome, and each rubber band needs to be placed in a fixed position manually in advance, which is not simple enough.

[0004] The above-mentioned automatic glove strapping machine is only one of the rubber band strapping machines on the market. Other strapping machines generally involve operation steps such as rubber band feeding, rubber band feeding, rubber band opening, product strapping, etc., and generally require the products in the collection basket to be manually taken out and sorted and stacked in advance. The process is complicated, the equipment occupies a large space, the maintenance cost is high, the product strapping efficiency is low, and the strapping flatness is poor. Summary of the invention

[0065] Specific implementation plan: see Figure 1-Figure 17 The present invention is a knitting machine with the functions of automatic stacking and rubber band bundling of products, comprising a knitting machine body 100, and a manipulator 200 and a material discharging platform 500 installed at the unloading end of the knitting machine body 100, the manipulator 200 is used to continuously transport the knitted product a to the top of the material discharging platform 500, the material discharging platform 500 is provided with a rotation auxiliary device 600 and a material pressing device 700, the knitting machine body 100 is also provided with a sorting and feeding device 300 and a material taking and bundling device 400, wherein the rotation auxiliary device 600 has:

[0066] The rotating disk 630 is installed above the material discharging platform 500, and the products a are placed on the rotating disk 630 in a stacked state; the first driving source cooperates to drive the rotating disk 630;

[0067] The pressing device 700 includes:

[0068] A lifting and adjusting assembly is installed on the unloading platform 500;

[0069] A second driving source cooperates to drive the lifting and adjusting component;

[0070] The pressure bar 750 is installed on the lifting and adjusting assembly, and the pressure bar 750 is located above the product a;

[0071] The sorting and feeding device 300 includes:

[0072] The belt assembly 330 is provided with a third driving source;

[0073] A storage position, installed at the end of the belt assembly 330, for storing a quantitative rubber band b;

[0074] The material taking and bundling device 400 has:

[0075] A drive assembly 410;

[0076] A transmission assembly, linked with the drive assembly 410;

[0077] A plurality of umbrella-shaped grippers 440 are installed on the transmission assembly at intervals along the circumferential direction, and all the umbrella-shaped grippers 440 perform synchronous pendulum motion between the storage position and the product a through the linkage of the driving assembly 410 and the transmission assembly.

[0078] Specifically, a first support frame 350 and a second support frame 510 are fixedly installed on the knitting machine body 100, wherein the sorting and feeding device 300 and the material picking and bundling device 400 are both installed on the first support frame 350, and the rotation auxiliary device 600 and the pressing device 700 are both installed on the second support frame 510. In this embodiment, the discharge platform 500 includes a second support frame 510 and an outer support plate 520 installed on the second support frame 510, and an induction switch is provided on the outer support plate 520, and the induction switch here is preferably a capacitive proximity switch 530.

[0079] The first support frame 350 is used to fix the sorting and feeding device 300 and the material picking and bundling device 400 on the frame of the knitting machine body 100, and the second support frame 510 is used to fix the rotation auxiliary device 600 and the material pressing device 700 on the frame of the knitting machine body 100, and finally form a knitting machine integrating product sorting, stacking and bundling functions.

[0080] In order to facilitate the understanding of the subsequent content, the workflow of the knitting machine involved in this embodiment for automatically stacking and bundling product a is briefly described here:

[0081] Product unloading and stacking: The robot 200 is installed at the unloading end of the knitting machine body 100, and is used to grab the products a woven by the knitting machine one by one onto the unloading platform 500, and specifically place them above the rotating disk 630. Here, the products a are stacked one by one on the rotating disk 630 to form a product stack. In the process of stacking each product a, the pressure bar 750 will first move upward under the drive of the lifting and adjusting component, so that the product a can be smoothly unloaded by the robot 200, and then the pressure bar 750 will press down and hold the product stack. At this time, the robot 200 will be retracted and the action of smoothing the top layer of product a will be completed.

[0082] Rotation of product stack and bundling action with rubber band b: When the number of products a in the product stack reaches a predetermined number, the robot 200 stops grabbing the material. At this time, the working mode of the rotation auxiliary device 600 is divided into three situations (the first driving source controls the rotation of the rotating disk 630):

[0083] 1. The part of the product stack that needs to be tied has been aligned with the conveying direction of the rubber band b: the rotating disk 630 does not rotate, and the material picking and bundling device 400 grabs the rubber band b from the storage position of the sorting and feeding device 300 through the umbrella-shaped gripper, and expands and conveys the rubber band b to be tied to the product stack;

[0084] 2. The part of the product stack that needs to be tied is not aligned with the conveying direction of the rubber band b: the rotating disk 630 rotates so that the part of the product stack that needs to be tied is aligned with the conveying direction of the rubber band b, and the material-taking and bundling device 400 grabs the rubber band b from the storage position of the sorting and feeding device 300 through the umbrella-shaped gripper 440, and expands and conveys the rubber band b to be tied to the product stack. Note that the rotating disk 630 can rotate multiple times here so that the material-taking and bundling device can bundle multiple parts of the product with the rubber band b;

[0085] 3. When the outer dimensions of the product stack do not fit the position where the material picking and bundling device 400 grabs the rubber band b for bundling (space needs to be left for bundling): the manipulator 200 pushes the product stack and partially moves it to the top of the outer support plate 520, that is, the position that the capacitive proximity switch 530 (or other types of sensors) can sense. At this time, the rotating disk 630 rotates at different angles and cooperates with the mechanical action of the manipulator 200 to enable the product stack to move 360° in all directions, thereby making the part of the product stack that needs to be bundled fit the position where the material picking and bundling device grabs the rubber band b for bundling.

[0086] Unloading of the bundled product stack: The robot 200 pushes the bundled product stack away from the rotating disk 630 and prepares for the next round of product stack loading and bundling. The bundled product stack can fall into a receiving frame or onto another conveying device.

[0087] As a preferred implementation of this embodiment, the material belt assembly 330 includes at least one material belt rod installed on the third driving source and spaced from each other, wherein at least one material belt rod is a screw rod, and all material belt rods are driven by the third driving source to rotate synchronously, and the rotation direction of the tooth grooves in all screw rods is consistent. In addition, a limit plate 340 is generally provided at the end of the storage position, and the limit plate 340 is used to prevent the rubber band b sorted to the storage position from escaping from the storage position.

[0088] Then, the third driving source includes a third motor 310 and a synchronous belt assembly 320, the synchronous belt assembly 320 includes a main step wheel 321 and at least one driven wheel 323, a synchronous belt 322 is provided between the driving wheel 321 and the driven wheel 323, the driving wheel 321 is linked and installed on the motor shaft of the third motor 310, and one end of the material carrying rod is connected to the driven wheel 323. In this embodiment, the third motor 310 drives the driving wheel 321 to work, and the driving wheel 321 drives the driven wheel 323 to work synchronously through the synchronous belt 322, thereby driving the material carrying rod installed on the driven wheel 323 to rotate, and the rotation of the material carrying rod will drive the rubber band b placed on the screw rod to be transported to the storage position.

[0089] It should be noted that in this embodiment, the rotation direction of the tooth groove of the screw in the material rod is required to be consistent. If there are both positive thread screw and negative thread screw, the positive thread screw and negative thread screw are driven to rotate in opposite directions to ensure that the rotation direction of the tooth groove of all screws is consistent. In addition, the rubber band b is placed on the material rod at will, and does not need to be deliberately arranged, as long as it is not placed in the storage position. The third motor 310 is used to cooperate with the synchronous belt assembly 320 and the material belt assembly 330 to transport the rubber band b to the storage position and make it present a relatively fixed state. Then, the reverse rotation of the screw rod is used to make the remaining rubber band b that has not entered the storage position move downward, so that the materials that need to be taken and the materials that do not need to be taken can be separated, and the rubber band b can be sorted, which is convenient for the subsequent manipulator 200 to take the rubber band b.

[0090] In addition, the contour of the rubber band b and the socket of the screw rod need to match each other. When the rubber band b enters the socket, it becomes relatively fixed. At this time, the rubber band b can move along with the socket. Moreover, the height of the storage position corresponds to the sum of the inner diameters of the maximum set number of rubber bands b, so that the storage position is sufficient to store the required number of rubber bands b.

[0091] As another preferred implementation manner of this embodiment, the driving assembly 410 includes a fourth motor 411 and a driving rod 412 connected to each other, a mounting head 413 is provided at one end of the driving rod 412, and the transmission assembly includes a fixing auxiliary part 420, a worm 430 and a worm wheel 450, wherein the worm 430 and the fixing auxiliary part 420 are both fixedly mounted on the mounting head 413, the worm wheel 450 is mounted on the fixing auxiliary part 420 by a connecting screw 443, the worm wheel 450 is meshed with the worm 430, and the umbrella-shaped gripper 440 is fixedly mounted on the worm wheel 450.

[0092] It should be noted that the fixing auxiliary component 420 includes a fixing body and a plurality of fixing joints evenly spaced along the circumference of the fixing body. The worm gear 450 is fixedly mounted on the fixing joints by connecting screws 443 , and ensures that all worm gears 450 are engaged with the worm 430 .

[0093] In order to make the driving rod 412 rotate more smoothly and increase the service life of the product, a bearing 414 and a coupling 415 are generally installed at the end of the driving rod 412.

[0094] In addition, the free end of the umbrella-shaped gripper 440 is provided with a snap-in socket 441 for the rubber band b to snap-in, and the end of the snap-in socket 441 close to the worm gear 450 is provided with a limit block 442 extending outward, and the umbrella-shaped gripper 440 is provided with a clearance groove 444 for accommodating the edge of the fixing auxiliary component 420.

[0095] In this embodiment, the second support frame 510 includes an integrally formed connecting plate 511 and a bottom supporting plate 512, the connecting plate 511 is fixedly mounted on the knitting machine body 100, the rotation auxiliary device 600 also includes a plurality of diamond-shaped bull's eyes 620 mounted on the upper end of the bottom supporting plate 512, and the rotating disk 630 is placed above the diamond-shaped bull's eyes 620. The first driving source is the fifth motor 610, and the free end of the motor shaft of the fifth motor 610 is welded to the center of the rotating disk 630.

[0096] Working principle of the material picking and bundling device: the fourth motor 411 drives the driving rod 412 to rotate, and the worm 430 fixedly mounted on the mounting head 413 will rotate synchronously. At this time, the worm wheel 450 meshing with the worm 430 will rotate, and then the umbrella-shaped gripper 440 mounted on the worm wheel 450 will rotate with the worm wheel 450 as the rotation point. Figure 7-Figure 9 , Figure 7 This is a state diagram of the material rubber band b being taken from the storage position of the self-sorting feeding device, at which time the umbrella-shaped gripper 440 rotates to the storage position; Figure 8 This is a state diagram when the rubber band b is expanded to the maximum during the process of taking the rubber band, and at this time, the umbrella-shaped gripper 440 rotates to be perpendicular to the driving rod 412; Fig. 9The diagram shows a state in which the rubber band b is sleeved onto the bundling position of the product a during the process of taking the rubber band. At this time, the umbrella-shaped gripper 440 rotates to the bundling position of the product a. When bundling is completed, the umbrella-shaped gripper 440 forms a pendulum-like motion through the reverse rotation of the worm gear 450 and the worm 430, swings back to the storage position, and then performs the next round of action. In this way, the bundling of the product a can be continuously achieved, and the work efficiency is extremely high.

[0097] In this embodiment, the manipulator 200 includes a rocker transmission assembly 210, a clamping assembly 220 and a telescopic drive assembly 230, wherein the rocker transmission assembly 210 includes an active rod 211, a connecting rocker 212 and a support sleeve 213, the active rod 211 is connected to a driving motor, and the connecting rocker 212 is located between the active rod 211 and the support sleeve 213; the clamping assembly 220 includes a first motor 221, a push rod 222 and a chuck 223, the first motor 221 controls the operation of the chuck 223 by driving the linear displacement of the push rod 222; the telescopic drive assembly 230 includes a second motor 231 and a first rack 233, the first rack 233 passes through the support sleeve 213, the motor shaft of the second motor 231 is provided with a first gear 232 meshing with the first rack 233, and the end of the first rack 233 is connected to the chuck 223.

[0098] When the support sleeve 213 rotates to be parallel to the upper end surface of the rotating disk 630, the pressure bar 750 presses one end of the product a, and the clamp 223 slightly loosens the product a and moves horizontally toward the other end of the product a following the extension and contraction of the first rack 233 to smooth the product a.

[0099] Working principle of the manipulator: the driving motor drives the active rod 211 to work, and the swing rod movement is formed by connecting the swing rod 212 and the support 213 sleeve, so that the support sleeve 213 moves. Since the first rack 233 passes through the support sleeve 213 and is fastened to the support sleeve 213, it is equivalent to the telescopic drive component 230 being installed on the support sleeve 213. In addition, the clamp 223 is connected to the end of the first rack 233, which is equivalent to the clamping component 220 being installed on the first rack 233. The movement of the support sleeve 213 will drive the telescopic drive component 230 and the clamping component 220 to move together.

[0104] The second driving source is a sixth motor 710 . A second gear meshing with the second rack 720 is disposed on the motor shaft of the sixth motor 710 .

[0105] In this embodiment, the sixth motor 710 controls the up and down displacement of the second rack 720 by driving the second gear, and drives the connecting arm 740 and the pressure bar 750 installed at the upper end of the second rack 720 to move up and down, so that the pressure bar 750 cooperates to press the product stack during the process of smoothing the product a, and ensures that the edges of the product stack are laid flat, and all products a are in a smoothed state.

[0106] In order to accurately control the lifting and lowering amplitude of the lifting and adjusting assembly and make the pressure bar 750 just abut and slightly press down on the product a located on the top layer of the product stack, it is preferred to install a magnetic switch 730 on the second rack 720, and the magnetic switch 730 is fixed on the sixth motor 710, but maintains a close abutment state with the second rack 720. Therefore, the magnetic switch 730 can accurately measure the displacement of the second rack 720 in the up and down directions.
