Description

Technical Field

[0001] The present invention relates to the technical field of sock packaging, and more specifically, to a sock packaging machine and a method for using the same. Background Art

[0002] Socks are a kind of clothing item worn on the feet, which are necessities and consumables in people's lives, with a short renewal cycle and a huge market. After socks are produced, in order to facilitate display and sales, socks need to be packaged.

[0003] Traditional packaging equipment for socks mainly consists of a conveying mechanism and a packaging mechanism. The conveying mechanism is used to convey folded or wound socks to the packaging area. The packaging mechanism imports the folded or wound socks into a packaging bag and performs the work of sealing the bag mouth and cutting individual packaging bags. However, during the process of conveying the folded or wound socks, the following problems still exist:

[0004] First, due to the different sizes and thicknesses of socks, the thickness of the folded or wound socks will also vary. For thin long stockings, mid-calf stockings, and ankle socks, the stability between the folded surfaces is relatively strong and the thickness is relatively low. Therefore, they will not become loose during the conveying process, but may still shift out of the middle position of the conveying mechanism, resulting in the final packaging process being unable to align with the bag mouth, and manual correction is required, which is a relatively cumbersome process.

[0005] Second, for thick socks, due to the influence of their materials, after being folded, the stability between the folded surfaces of the thick socks is poor, that is, they are very likely to become loose, resulting in uneven shapes of the packaged socks, affecting the appearance. Even the size of the loose socks may exceed the bag mouth size, resulting in the inability to complete the packaging smoothly, and manual correction is also required. At the same time, the top of the folded thick socks is in a fluffy state, and it is very easy to hang on the bag mouth during the process of entering the packaging bag, which is very likely to affect the subsequent sealing work.

[0006] In order to address the above problems, there is an urgent need for a sock packaging machine and a method for using the same. Summary of the Invention

[0007] The purpose of the present invention is to provide a sock packaging machine and a method for using the same to solve the problems raised in the above background art.

[0008] To achieve the above object, one of the objects of the present invention is to provide a sock packaging machine, which includes a packaging table, a main conveyor belt installed on the side of the packaging table, and a secondary conveyor belt installed on the side of the main conveyor belt. A driving device is connected between the main conveyor belt and the secondary conveyor belt. Through the driving device, the main conveyor belt and the secondary conveyor belt are driven to synchronously transmit, so as to convey socks in different states. A plurality of pairs of horizontal clamping plates are slidably arranged on the outer side of the secondary conveyor belt. An interval for positioning the socks during the conveying process is reserved between the two horizontal clamping plates. Vertical clamping plates are arranged on the adjacent sides of the two horizontal clamping plates. The vertical clamping plates slide along the vertical direction of the side surface of the horizontal clamping plates and are located directly above the interval formed by the two horizontal clamping plates;

[0009] A horizontal limiting component is arranged between the side surfaces of each pair of horizontal clamping plates to limit the horizontal sliding route of each pair of horizontal clamping plates. When each pair of horizontal clamping plates follow the horizontal limiting component and are driven to the middle area, the two horizontal clamping plates approach each other along the outer side of the secondary conveyor belt, shortening the interval width and gathering the socks located at the inner end of the interval to the middle area thereof;

[0010] A vertical limiting component is arranged at the top of the horizontal limiting component. The vertical limiting component limits the vertical sliding route of the vertical clamping plates, so that when each vertical clamping plate follows the horizontal clamping plate at the corresponding position and is driven to the middle area, the vertical limiting component applies a thrust to the top of the vertical clamping plate, prompting the vertical clamping plates that are in contact with each other above the interval to move downward to squeeze the fluffy socks.

[0011] As a further improvement of this technical solution, the horizontal limiting component is a pair of horizontally arranged horizontal frames. A plurality of fixing rods for fixing their positions are connected to the side surfaces of the two horizontal frames. The two horizontal frames are respectively arranged at the horizontal positions on both sides of the secondary conveyor belt. The side surfaces of the adjacent horizontal clamping plates are in sliding contact with the side surfaces of the corresponding horizontal frames and are parallel to each horizontal clamping plate. A horizontal sliding area for each pair of horizontal clamping plates is formed between the two horizontal frames, and the width of both ends of the horizontal sliding area is greater than the width of the middle position thereof.

[0012] As a further improvement of this technical solution, the vertical limiting component includes a folding plate. The folding plate is arranged at the middle upper position of the secondary conveyor belt. A plurality of connecting plates are arranged on the side surface of the folding plate. The bottom ends of the connecting plates are fixed at the side surface positions of the horizontal frames. The folding plate is in a Z-shaped structure, and the height of the folding plate near the main conveyor belt end is lower than the height of the other end.

[0013] As a further improvement of this technical solution, a plurality of sliding grooves are formed on the outer side of the auxiliary conveyor belt. A sliding block is provided at the bottom end of the horizontal clamping plate, and the sliding block is slidably engaged with the inner end of the sliding groove. An inner column is fixedly arranged at the inner end of the sliding groove. The two sliding blocks are respectively sleeved on the outer sides of both ends of the inner column, and a limiting spring is connected between the side surfaces of the two sliding blocks and the middle position of the inner column.

[0014] As a further improvement of this technical solution, clamping rods are arranged on both sides of the outer end of the sliding groove. The two clamping rods are respectively arranged on both sides of the two horizontal clamping plates, and cooperate with the two horizontal clamping plates to form a space surrounded on four sides for defining the placement area of the socks.

[0015] As a further improvement of this technical solution, a side groove is formed on the side surface of the horizontal clamping plate. One side of the vertical clamping plate extends into the inner end of the side groove and slides vertically along the inner end of the side groove. A sliding column is arranged at the inner end of the side groove. The side surface of the vertical clamping plate is sleeved on the outer side of the sliding column, and a reset spring is connected between the bottom end position of the side surface of the vertical clamping plate and the bottom end position of the sliding column.

[0016] As a further improvement of this technical solution, a top groove is formed at the top end of the vertical clamping plate. A plurality of rollers are arranged at equal intervals at the inner end of the top groove, and the rollers are in rolling connection with the inner end of the top groove.

[0017] As a further improvement of this technical solution, a pressing plate is arranged at the bottom end of the vertical clamping plate. Plug posts are arranged at the respective corner positions of the top end of the pressing plate, and the plug posts are in plug-in fit with the corresponding positions at the bottom end of the vertical clamping plate. A buffer spring is connected between the top end of the plug post and the inner end of the vertical clamping plate.

[0018] The second object of the present invention is to provide a method for using a sock packaging machine, including the following method steps:

[0019] S1. Place the socks to be packaged in turn at the inner ends of the intervals formed by each pair of horizontal clamping plates. Drive the main conveyor belt and the auxiliary conveyor belt to move synchronously through the driving device, so that the auxiliary conveyor belt drives each pair of horizontal clamping plates to carry the socks to be packaged and move synchronously towards the packaging table position;

[0020] S2. Cooperate with the horizontal limiting component to limit the horizontal movement position of each pair of horizontal clamping plates, so that when each pair of horizontal clamping plates passes through the middle area of the horizontal limiting component, the horizontal limiting component applies a thrust to the two horizontal clamping plates, prompting the two horizontal clamping plates to approach each other, shortening the interval width formed therebetween, thereby synchronously pushing the socks that have left the middle area on both sides to gather them in the middle area;

[0021] S3. Each vertical clamping plate follows the horizontal displacement of the corresponding horizontal clamping plate synchronously, and fits against the side surface of the vertical clamping plate on the opposite side. When the two mutually - fitted vertical clamping plates are in the middle area, they will be squeezed by the vertical limiting component, prompting the two mutually - fitted vertical clamping plates to move vertically downward along the upper part of the interval, so as to squeeze the loose socks.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. In the sock packaging machine and its using method, by applying a thrust to the two horizontal clamping plates through the horizontal limiting component, the two horizontal clamping plates are prompted to approach each other, shortening the width of the interval formed between them, so as to synchronously push the socks that have left the middle area on both sides, making them gather in the middle area. At the same time, each vertical clamping plate follows the horizontal displacement of the corresponding horizontal clamping plate synchronously, and fits against the side surface of the vertical clamping plate on the opposite side. When the two mutually - fitted vertical clamping plates are in the middle area, they will be squeezed by the vertical limiting component, prompting the two mutually - fitted vertical clamping plates to move vertically downward along the upper part of the interval, so as to squeeze the loose socks and shape them, continuously maintaining the folded or wound state, and improving the folding or winding stability of the socks before packaging.

[0024] 2. In the sock packaging machine and its using method, by setting the roller, the contact area between the top of the vertical clamping plate and the bottom of the folding plate is reduced. Since the contact area is proportional to the frictional resistance, reducing the contact area reduces the frictional resistance formed between the two, thereby reducing the interference during the position adjustment of the vertical clamping plate.

[0041] Embodiment 1

[0042] Please refer to Figures 1-7As shown in the figure, one of the purposes of this embodiment is to provide a sock packaging machine, which includes a packaging table 10, a main conveyor belt 20 installed on the side of the packaging table 10, and a secondary conveyor belt 30 installed on the side of the main conveyor belt 20. A driving device 210 is connected between the main conveyor belt 20 and the secondary conveyor belt 30. The main conveyor belt 20 and the secondary conveyor belt 30 are driven to synchronously transmit by the driving device 210 to convey socks in different states. A plurality of pairs of horizontal clamping plates 60 are slidably arranged on the outer side of the secondary conveyor belt 30. An interval for positioning the socks during the conveying process is reserved between the two horizontal clamping plates 60. Vertical clamping plates 610 are arranged on the adjacent sides of the two horizontal clamping plates 60. The vertical clamping plates 610 slide along the vertical direction of the side of the horizontal clamping plates 60 and are located directly above the interval formed by the two horizontal clamping plates 60.

[0043] A horizontal limiting component 40 is arranged between the sides of each pair of horizontal clamping plates 60 to limit the horizontal sliding route of each pair of horizontal clamping plates 60. When each pair of horizontal clamping plates 60 follows the horizontal limiting component 40 to be transmitted to the middle area, the two horizontal clamping plates 60 approach each other along the outer side of the secondary conveyor belt 30, shortening the interval width, and gathering the socks located at the inner end of the interval to the middle area thereof.

[0044] A vertical limiting component 50 is arranged at the top of the horizontal limiting component 40. The vertical limiting component 50 limits the vertical sliding route of the vertical clamping plates 610, so that when each vertical clamping plate 610 follows the corresponding horizontal clamping plate 60 to be transmitted to the middle area, the vertical limiting component 50 applies a thrust to the top thereof, prompting the vertical clamping plates 610 that are attached to each other above the interval to move downward to squeeze the fluffy socks.

[0045] During specific use, during the packaging process of the socks, first place the socks to be packaged in turn at the inner end of the interval formed by each pair of horizontal clamping plates 60. The driving device 210 drives the main conveyor belt 20 and the secondary conveyor belt 30 to move synchronously, prompting the secondary conveyor belt 30 to drive each pair of horizontal clamping plates 60 to carry the socks to be packaged and move synchronously towards the position of the packaging table 10. During this process, due to the different placement states of different socks, it is easy for the socks to deviate from the middle area of the main conveyor belt 20 and the secondary conveyor belt 30, or for the socks that are folded or wound before and after transmission to become loose, resulting in the inability to smoothly pass through the bag mouth position to complete the packaging work.

[0046] Therefore, it is necessary to cooperate with the horizontal limit component 40 to limit the horizontal movement positions of each pair of horizontal clamping plates 60, so that when each pair of horizontal clamping plates 60 passes through the middle area of the horizontal limit component 40, the horizontal limit component 40 applies a thrust force to the two horizontal clamping plates 60, prompting the two horizontal clamping plates 60 to approach each other, shortening the interval width formed therebetween, thereby synchronously pushing the socks that have left the middle area on both sides, making them gather in the middle area. At the same time, each vertical clamping plate 610 follows the corresponding horizontal clamping plate 60 to move horizontally synchronously and fits against the side of the vertical clamping plate 610 on the opposite side. When the two mutually attached vertical clamping plates 610 are in the middle area, they will be squeezed by the vertical limit component 50, prompting the two mutually attached vertical clamping plates 610 to move vertically downward along the upper side of the interval, squeezing the loose socks and shaping them, continuously maintaining the folded or rolled state, improving the folding or rolling stability of the socks before packaging. The socks after orientation will maintain a stable state and follow the secondary conveyor belt 30 to be guided to the middle position of the main conveyor belt 20, and then be transported to the packaging table 10 through the main conveyor belt 20 for packaging. Moreover, the height of the secondary conveyor belt 30 is higher than that of the main conveyor belt 20, and there is a gap between the two for the horizontal clamping plates 60 to pass through freely. At the same time, the interval width formed between the two horizontal clamping plates 60 is greater than the width of the main conveyor belt 20, so they will not contact each other during the transmission process. When the horizontal clamping plates 60 move to the end position of the secondary conveyor belt 30, the inner end of the interval formed by the two horizontal clamping plates 60 slopes downward, sliding the socks onto the upper side of the main conveyor belt 20 for transportation.

[0047] Further, the horizontal limit component 40 is a pair of horizontally arranged horizontal frames 410. A number of fixing rods 420 for fixing their positions are connected to the sides of the two horizontal frames 410. The two horizontal frames 410 are respectively arranged at the horizontal positions on both sides of the secondary conveyor belt 30. The side surfaces of the adjacent horizontal clamping plates 60 are in close contact and sliding with the side surfaces of the corresponding horizontal frames 410, and are parallel to each horizontal clamping plate 60. A horizontal sliding area for each pair of horizontal clamping plates 60 is formed between the two horizontal frames 410, and the width of both ends of the horizontal sliding area is greater than the width of its middle position;

[0048] As Figures 2-3 shown, in the initial state, in order to increase the interval width and reduce the obstruction during the sock placement process, each pair of horizontal clamping plates 60 slides from one end of the horizontal sliding area to the other end. The interval width formed by each pair of horizontal clamping plates 60 located at the end of the horizontal sliding area is at the maximum value. Driven by the secondary conveyor belt 30, each pair of horizontal clamping plates 60 will carry the socks from the end of the horizontal sliding area to the middle position. During this process, the width of the horizontal sliding area passed by each pair of horizontal clamping plates 60 gradually decreases. In order to pass smoothly, the two horizontal clamping plates 60 passing through will approach each other horizontally, shortening the interval width. At the same time, the socks not in the middle position of the interval are pushed to gather them to the middle position for alignment with the later bag mouth position.

[0049] Furthermore, the vertical limit component 50 includes a folding plate 510 which is arranged above the middle of the auxiliary conveyor belt 30. A plurality of connecting plates 520 are arranged on the side of the folding plate 510, and the bottom ends of the connecting plates 520 are fixed at the side position of the horizontal frame 410. The folding plate 510 is in a Z-shaped structure, and the height of one end of the folding plate 510 close to the main conveyor belt 20 is lower than that of the other end;

[0050] As Figures 2 to 3 shown, during the process of adjusting the position of the vertical clamping plates 610, when the horizontal clamping plate 60 is at the end of the horizontal sliding area, at this time, each vertical clamping plate 610 is at the highest point. As the vertical clamping plates 610 move synchronously with the horizontal clamping plate 60 to the middle position of the horizontal sliding area, each vertical clamping plate 610 first moves horizontally synchronously with the horizontal clamping plate 60, and the vertical clamping plates 610 are mutually attached. At the same time, the mutually attached vertical clamping plates 610 move from the highest point of the folding plate 510 to the lowest point. During this process, in order to smoothly pass through the bottom end of the folding plate 510, the two mutually attached vertical clamping plates 610 move downward along the trajectory of the bottom end of the folding plate 510, and apply pressure to the top of the socks that have completed the position correction in the middle area below during the downward movement, compact the fluffy socks, and perform plastic treatment on the fluffy socks before packaging to maintain their stability.

[0051] Specifically, a plurality of chutes 310 are formed on the outer side of the auxiliary conveyor belt 30. The bottom end of the horizontal clamping plate 60 is provided with sliders 630 that slide with the inner ends of the chutes 310. Inner columns 320 are fixedly arranged at the inner ends of the chutes 310. The two sliders 630 are respectively sleeved on the outer sides of both ends of the inner column 320, and limiting springs 321 are connected between the sides of the two sliders 630 and the middle position of the inner column 320. It should be noted that there is a height difference between the area for placing socks and the chutes 310. During the extrusion process, the socks extending towards the chutes 310 will not contact the limiting springs 321, thereby preventing the limiting springs 321 under stress from being hooked to the socks;

[0052] As Figure 5As shown, after the two horizontal clamping plates 60 move with the auxiliary conveyor belt 30 to the middle position of the horizontal sliding area, each horizontal clamping plate 60 will be squeezed by the horizontal limiting component 40 on the corresponding side, prompting the two horizontal clamping plates 60 to approach each other. During this process, the slider 630 at the bottom end of the horizontal clamping plate 60 will slide along the inner end of the corresponding chute 310 and slide along the outside of the inner column 320, exerting a thrust on the limiting spring 321, prompting the limiting spring 321 to be in a compressed state until the horizontal clamping plate 60 continues to move with the auxiliary conveyor belt 30 to the end position of the horizontal sliding area. At this time, since the distance formed at the end position of the horizontal sliding area is greater than that at the middle position, each limiting spring 321 will lose the external force and drive the two horizontal clamping plates 60 to move away from each other in the reverse direction, returning to the initial position again, so as to avoid continuous fixation resulting in the inability to smoothly convey the positioned socks from the auxiliary conveyor belt 30 to the main conveyor belt 20.

[0053] In addition, clamping rods 330 are arranged on both sides of the outer end of the chute 310. The two clamping rods 330 are respectively arranged on both sides of the two horizontal clamping plates 60, and cooperate with the two horizontal clamping plates 60 to form a space surrounded on four sides for defining the placement area of the socks.

[0054] As Figure 4 shown, in order to prevent the socks from detaching during the placement process, that is, protruding from both sides of the interval, resulting in a reduction in the extrusion surface of the later folding plate 510, so that only part of the area of the placed socks is squeezed. At this time, a pair of clamping rods 330 are arranged to cooperate with the two horizontal clamping plates 60 to form a space surrounded on four sides to define the placement area of the socks, preventing the worker from misplacing and detaching from the inner end of the interval, which affects the later extrusion effect.

[0055] In addition, a side groove 620 is formed on the side surface of the horizontal clamping plate 60. One side of the vertical clamping plate 610 extends into the inner end of the side groove 620 and slides vertically along the inner end of the side groove 620. A sliding column 621 is arranged at the inner end of the side groove 620. The side surface of the vertical clamping plate 610 is sleeved on the outside of the sliding column 621. A return spring 622 is connected between the bottom end position of the side surface of the vertical clamping plate 610 and the bottom end position of the sliding column 621.

[0056] As Figure 6As shown in the figure, when the vertical splint 610 is squeezed by the lowest point of the folding plate 510, it will vertically move downward along the side of the side groove 620. Its bottom end gradually contacts the upper part of the fluffy sock and squeezes it, completing the plastic work on the sock during the conveying process. At the same time, during the downward movement of the vertical splint 610, pressure will be applied to the return spring 622, causing it to compress downward and be in a stressed state until the entire vertical splint 610 follows the horizontal splint 60 to move out of the middle position of the horizontal sliding area, that is, the vertical splint 610 moves out of the lowest point position of the folding plate 510. At this time, the return spring 622 loses the external pressure and will return to its original state, overcoming the gravity of the vertical splint 610 to drive it to reset and return to the initial position, that is, losing the squeezing state of the sock to restore the free placement state of the sock, so as to maintain the plastic state and smoothly transition to the main conveyor belt 20 along the auxiliary conveyor belt 30.

[0057] Furthermore, a top groove is provided at the top end of the vertical splint 610, and a number of rollers 611 are equidistantly arranged at the inner end of the top groove. The rollers 611 are in rolling connection with the inner end of the top groove;

[0058] As Figure 6 shown in the figure, during the contact process between the top end of the vertical splint 610 and the bottom end of the folding plate 510, frictional resistance will be generated between the two, and this frictional resistance will cause interference between the two, affecting the position adjustment of the vertical splint 610. At this time, the contact area between the top end of the vertical splint 610 and the bottom end of the folding plate 510 is reduced by the provided rollers 611, and the contact area is proportional to the frictional resistance. Reducing the contact area reduces the frictional resistance formed between the two, thereby reducing the interference received during the position adjustment of the vertical splint 610.

[0059] As Figure 7 shown in the figure, still further, a pressing plate 640 is provided at the bottom end of the vertical splint 610. Plug posts 641 are provided at each corner position of the top end of the pressing plate 640. The plug posts 641 are in plug-in fit with the corresponding positions at the bottom end of the vertical splint 610. A buffer spring 612 is connected between the top end of the plug post 641 and the inner end of the vertical splint 610. When the vertical splint 610 is squeezed by the folding plate 510, it will drive the pressing plate 640 to move downward synchronously to squeeze the fluffy sock. At this time, the pressing plate 640 will be in direct contact with the sock, and the pressure generated by the direct contact will be buffered by the elastic force generated by each plug post 641, avoiding excessive pressure resulting in too deep creases in the sock and affecting the later use effect.

[0060] The second object of this embodiment is to provide a method of using a sock packaging machine, including the following method steps:

[0061] S1. Place the socks to be packaged successively at the inner ends of the intervals formed by each pair of horizontal clamping plates 60. Drive the main conveyor belt 20 and the auxiliary conveyor belt 30 to move synchronously through the driving device 210, so as to prompt the auxiliary conveyor belt 30 to drive each pair of horizontal clamping plates 60 to carry the socks to be packaged and move synchronously towards the packaging table 10;

[0062] S2. Cooperate with the horizontal limiting component 40 to limit the horizontal movement positions of each pair of horizontal clamping plates 60, so that when each pair of horizontal clamping plates 60 pass through the middle area of the horizontal limiting component 40, the horizontal limiting component 40 applies a thrust to the two horizontal clamping plates 60, prompting the two horizontal clamping plates 60 to approach each other, shortening the interval width formed therebetween, thereby synchronously pushing the socks that have left the middle area on both sides to gather them in the middle area;

[0063] S3. Each vertical clamping plate 610 follows the corresponding horizontal clamping plate 60 to move horizontally synchronously and fits against the side surface of the vertical clamping plate 610 on the opposite side. When the two mutually fitted vertical clamping plates 610 are in the middle area, they will be squeezed by the vertical limiting component 50, prompting the two mutually fitted vertical clamping plates 610 to move vertically downward along the upper part of the interval to squeeze the loose socks.

[0064] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
