Description

Technical Field

[0001] The utility model relates to the field of sock turning machines, in particular to a sock turning machine with a sock unloading mechanism. Background Art

[0002] The sock turning machine includes a clamping mechanism, a sock turning sleeve and a negative pressure component. The clamping mechanism puts the socks on the outer wall of the sock turning sleeve and then moves in the opposite direction to turn the socks. At the same time, the negative pressure component works to generate negative pressure in the sock turning sleeve, so that the sock turning sleeve sucks away the turned socks.

[0003] When the socks fold during the sock turning process, resulting in increased thickness, the socks become difficult to enter the sock turning sleeve and cannot be sucked away. When the negative pressure component stops working, the negative pressure in the sock turning sleeve disappears, and the socks fall down on their own. However, because the gripping mechanism has claws, if the socks are caught in the claws, they cannot fall down smoothly, affecting the subsequent sock turning process. Utility Model Content

[0019] The second blade is made of flexible material.

[0020] After adopting the above technical solution, the utility model has the following beneficial effects.

[0021] 1. The utility model proposes a sock turning machine, which provides a rotating first roller assembly under the sock turning sleeve, so that the socks that have not been sucked away are driven by the rolling first roller assembly after falling and are separated from the sock turning machine. Even if the socks are hooked by the clamping mechanism, due to the force between the first roller assembly and the socks, the socks in contact with the first roller assembly can be driven by the first roller assembly to separate from the clamping mechanism to realize the sock withdrawal, thereby avoiding the clamping mechanism from hooking the socks that have not been sucked away and affecting the normal operation of the sock turning machine, thereby avoiding the retention of unturned socks and affecting the subsequent sock turning process, and improving the sock withdrawal efficiency of the sock turning machine for unturned socks.

[0022] 2. By adopting the first belt and the socks falling on the first belt, the friction between the socks and the first belt makes it easy for the socks falling on the first roller assembly to be driven by the first roller assembly and thus detach from the sock turning machine; secondly, the first roller assembly also includes a first roller shaft arranged on the front side and a first driven shaft arranged on the rear side, and the first belt is sleeved on the first roller shaft and the first driven shaft, thereby increasing the effective area of ​​the first belt, making it easier for the first belt to catch the fallen socks, and the contact area between the first belt and the socks is larger, which increases the friction between the first belt and the socks, making it easier for the socks to be driven by the first roller assembly and thus detach from the sock turning machine, thereby improving the efficiency of the sock turning machine for removing socks that have not been turned over.

[0023] 3. A waist hole connected to the second fixing bracket is provided on the bottom of the base plate, and a screw hole is provided on the second fixing bracket. The screw passes through the waist hole to screw the second fixing bracket to the base plate. In this way, the installation position of the second fixing bracket on the base plate can be adjusted. On the one hand, the first roller shaft and the first driven shaft can be adapted to different belts. On the other hand, the adjustment of the position of the second fixing bracket changes the tension of the first belt, so that the first belt is not too tight or over-fed, thereby increasing the service life of the first belt and maintaining the friction between the first belt and the socks.

[0024] 4. Through the first roller shaft and a plurality of first blades circumferentially arranged on the first roller shaft, the friction between the socks and the first blades and the impact force of the first blades on the socks make it easy for the socks to separate from the clamping mechanism and thus escape from the sock turning machine even if the socks are hooked by the clamping mechanism; the first blades are made of flexible material, which avoids the socks being damaged when contacting the socks due to the use of too hard materials. The socks that have escaped the sock turning machine can be further packaged and sold after being turned over again.

[0025] 5. After the socks fall, they land in the sock discharge area. The force between the socks and the first roller assembly drives the socks to move forward into the sock discharge area. By reasonably setting the spacing of the sock discharge gap, when the socks pass through the sock discharge gap, they are acted upon by the second roller assembly and the first roller assembly respectively. Moreover, since the first roller assembly and the second roller assembly at least partially overlap in the sock discharge area, the force acting on the socks by the first roller assembly and the second roller assembly is further increased. Even if the socks are hooked on the clamping mechanism, they can be easily detached, thereby improving the efficiency of the sock turning machine for removing socks that have not been turned over properly.

[0026] 6. The first roller assembly and the second roller assembly rotate in opposite directions through a pair of meshing gears. The transmission assembly between the first roller assembly and the second roller assembly is relatively simple, and the gear meshing solution is economical and reliable, which is conducive to reducing the cost of the socks removal mechanism.

[0027] 7. Since the second roller assembly exerts a force on the socks above, the gravity of the socks does not act on the second roller assembly, so the friction between the two is very small. By arranging multiple friction parts axially at intervals on the second roller shaft, the rotation of the second roller shaft causes the friction parts to contact the socks and generate friction, thereby driving the socks to move forward, further increasing the force of the second roller assembly on the socks to separate from the sock turning machine, and improving the sock removal effect of the sock turning machine.

[0028] 8. This arrangement further increases the force exerted by the second roller assembly on the socks and improves the sock-removing effect of the sock-turning machine. The friction portion is made of a flexible material, which, on the one hand, can increase the friction between the friction portion and the socks, and on the other hand, prevents the friction portion from damaging the socks when the second roller assembly rotates.

[0029] 9. By providing a second belt on the second roller assembly to cooperate with the first belt, the friction between the second roller assembly and the socks is increased, the force of the socks-removing mechanism on the socks is increased, and the socks-removing effect of the socks-turning machine is improved; at the same time, the second belt has a rough outer surface, which further increases the friction between the second roller assembly and the socks, further increases the force of the socks-removing mechanism on the socks, and further improves the socks-removing effect of the socks-turning machine.

[0030] 10. By providing a second roller shaft and a plurality of second blades circumferentially arranged on the second roller shaft, the friction between the socks and the second blades and the impact force of the second blades on the socks increase the force of the sock-removing mechanism on the socks, making it easier for the socks to detach from the sock-turning machine. At the same time, the second blades are made of flexible materials, which avoids the second blades being made of too hard materials and causing damage to the socks when they come into contact with the socks. The socks that have detached from the sock-turning machine can continue to be packaged and sold after being turned over again.

DETAILED DESCRIPTION

[0045] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0046] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "clockwise", "counterclockwise" and the like to indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, unless otherwise specified, "plurality" or "several" means two or more, unless expressly limited otherwise.

[0048] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0049] like Figures 1 to 8 As shown, a sock turning machine proposed in an embodiment of the present invention includes a conveying mechanism 100, a clamping mechanism 200, a sock turning sleeve 300, and a negative pressure assembly. The conveying mechanism 100 is used to convey socks to be turned. The clamping mechanism 200 clamps the socks to be turned and moves from bottom to top, wrapping the socks around the outer wall of the sock turning sleeve 300. The clamping mechanism 200 then moves in the opposite direction to complete the sock turning and pushes the socks to the lower opening of the sock turning sleeve 300. The negative pressure assembly generates negative pressure inside the sock turning sleeve 300, and the turned socks are sucked out of the lower opening of the sock turning sleeve 300. The socks sucked into the sock turning sleeve 300 pass through the negative pressure pipe and enter the subsequent stacking process.

[0050] Among them, the specific working principle of the sock turning machine can refer to the patent application with publication number CN104652116A and name "A Sock Turning Machine".

[0051] In this embodiment, the sock turning machine also includes a sock withdrawal mechanism 400, which is arranged below the sock turning sleeve 300. The sock withdrawal mechanism 400 includes a motor 410 and a first roller assembly 420 driven by the motor 410 to rotate. The socks that are not sucked away by the sock turning sleeve 300 fall on the first roller assembly 420, and the rotation of the first roller assembly 420 drives the socks out of the sock turning machine.

[0052] When the clamping mechanism 200 causes the socks to fold and increase the thickness of the socks during the sock turning process, the negative pressure generated by the negative pressure component causes the socks to be sucked into the entrance of the sock turning sleeve 300 by the negative pressure. Due to the increased thickness of the socks, it is difficult for the socks to be sucked away by the sock turning sleeve 300. After the negative pressure component stops working, the negative pressure in the sock turning sleeve 300 disappears, and the socks that have not been sucked away fall down on their own. The fallen socks come into contact with the rotating first roller assembly 420. Due to the action force between the socks and the first roller assembly 420, the first roller assembly 420 drives the socks to move, so that the socks are separated from the sock turning machine.

[0053] The acting force between the socks and the first roller assembly 420 may be frictional force or other acting forces.

[0054] By arranging a rotating first roller assembly 420 under the sock turning sleeve 300, the socks that have not been sucked away are driven by the rolling first roller assembly 420 after falling and are separated from the sock turning machine. Even if the socks are hooked by the clamping mechanism 200, due to the force between the first roller assembly 420 and the socks, the socks in contact with the first roller assembly 420 can be driven by the first roller assembly 420 and thus separated from the clamping mechanism 200 to realize the sock withdrawal, thereby avoiding the clamping mechanism 200 hooking the socks that have not been sucked away and affecting the normal operation of the sock turning machine, thereby avoiding the retention of unturned socks and affecting the subsequent sock turning process, and improving the sock withdrawal efficiency of the sock turning machine for unturned socks.

[0055] In this embodiment, the sock unwinding mechanism 400 includes a base plate 411 and a fixing frame 412. The fixing frame 412 is mounted on the base plate 411, and the motor 410 is mounted on the fixing frame 412. The fixing frame 412 is connected to the base plate 411 via screws, and the motor 410 is also connected to the fixing frame 412 via screws. Two fixing frames 412 are provided, one on each side of the base plate 411.

[0056] In one embodiment, an explanation is given for a force between the sock and the first roller assembly 420. In this embodiment, as Figures 1 to 8As shown, the first roller assembly 420 includes a first roller shaft 421, a first driven shaft 422, and a first belt 423. The first roller shaft 421 is mounted on the motor shaft of the motor 410. The fixing frame 412 has a mounting slot. The first driven shaft 422 is rotatably restrained in the mounting slot by a bearing, thereby being rotatable relative to the fixing frame 412. The first belt 423 is sleeved at both ends by the first roller shaft 421 and the first driven shaft 422. The motor 410 drives the first roller shaft 421 to rotate, thereby driving the first belt 423 to rotate. Dropped socks land on the first belt 423.

[0057] In this embodiment, the force acting between the first roller assembly 420 and the socks is friction. Since the first belt 423 is made of a flexible material and has a high coefficient of friction on its outer surface, the falling socks come into contact with the rotating first belt 423. The friction between the socks and the first belt 423 drives the socks to move out of the sock turning machine.

[0058] By adopting the first belt 423 and the socks falling on the first belt 423, the friction between the socks and the first belt 423 makes it easy for the socks falling on the first roller assembly 420 to be driven by the first roller assembly 420 and thus detach from the sock turning machine; secondly, the first roller assembly 420 also includes a first roller shaft 421 arranged on the front side and a first driven shaft 422 arranged on the rear side, and the first belt 423 is sleeved on the first roller shaft 421 and the first driven shaft 422, thereby increasing the effective area of ​​the first belt 423, and the first belt 423 is more likely to catch the fallen socks, and the contact area between the first belt 423 and the socks is larger, which increases the friction between the first belt 423 and the socks, and the socks are more easily driven by the first roller assembly 420 and thus detach from the sock turning machine, thereby improving the efficiency of the sock turning machine for removing socks that have not been turned over.

[0059] In this embodiment, the first belt 423 is arranged horizontally. In this arrangement, the friction between the socks and the first belt 423 is maximized, and the socks are more easily driven by the rotating first belt 423 to escape from the sock turning machine.

[0060] In some other embodiments, the first belt 423 may also be arranged at an angle.

[0061] In this embodiment, the first belt 423 preferably has a rough outer surface. This arrangement further increases the friction between the first belt 423 and the socks, making it easier for the socks to be driven by the first roller assembly 420 and thus to escape from the sock turning machine.

[0062] In another preferred embodiment, the fixing frame 412 includes a first fixing frame 4121 and a second fixing frame 4122. The first fixing frame 4121 is arranged on the front side of the base plate 411, and the second fixing frame 4122 is arranged on the rear side of the base plate 411. A waist hole 4111 connected to the second fixing frame 4122 is provided on the bottom of the base plate 411. The second fixing frame 4122 is provided with a screw hole, and the screw passes through the waist hole 4111 to screw the second fixing frame 4122 to the base plate 411.

[0063] The motor 410 is mounted on the first fixing frame 4121 , and thus the first roller shaft 421 is mounted on the first fixing frame 4121 ; and the first driven shaft 422 is mounted on the second fixing frame 4122 .

[0064] In this way, the installation position of the second fixing frame 4122 on the base plate 411 can be adjusted. On the one hand, the first roller shaft 421 and the first driven shaft 422 can be adapted to different belts. On the other hand, the adjustment of the position of the second fixing frame 4122 changes the tension of the first belt 423, so that the first belt 423 will not be too tight or over-fed, thereby increasing the service life of the first belt 423 while maintaining the friction between the first belt 423 and the socks.

[0065] In one embodiment, another force acting between socks and the first roller assembly 420 is explained. In this embodiment, the first roller assembly 420 includes a first roller shaft 421 and a plurality of first blades circumferentially arranged on the first roller shaft 421. The motor 410 drives the first roller shaft 421 to rotate, thereby driving the first blades to rotate. The first roller shaft 421 is located below the sock turning sleeve 300. Falling socks are struck by the first blades and are released from the sock turning machine.

[0066] The width direction of the first blade is substantially perpendicular to the rotation direction of the first roller shaft 421 , so that the contact and striking area between the rotating first blade and the falling socks is maximized.

[0067] It is understandable that the width direction of the first blade and the rotation direction of the first roller shaft 421 may also form a certain angle.

[0068] In this embodiment, the force between the first roller assembly 420 and the socks is a combination of friction and striking force. The falling socks come into contact with the rotating first blade, which drives the socks to move and thus escape from the sock turning machine.

[0069] Through the first roller shaft 421 and a plurality of first blades circumferentially arranged on the first roller shaft 421, the friction between the socks and the first blades and the striking force of the first blades on the socks make it easy for the socks to separate from the clamping mechanism 200 and thus escape from the sock turning machine even if the socks are hooked by the clamping mechanism 200.

[0070] In a preferred embodiment, the first blade is made of a flexible material, wherein the flexible material may be rubber, silicone or plastic.

[0071] Such arrangement avoids the situation that the first blade is made of too hard material and causes the socks to be damaged when it comes into contact with the socks, and the socks that have left the sock turning machine can continue to be packaged and sold after being turned over again.

[0072] In one embodiment, in order to further improve the sock discharging efficiency of the sock discharging mechanism 400, as shown in FIG. Figures 2 to 8 As shown, the sock removal mechanism 400 further includes a second roller assembly 430 and a transmission assembly 440. The first roller assembly 420 drives the second roller assembly 430 to rotate in the opposite direction of the first roller assembly 420 via the transmission assembly 440. The second roller assembly 430 is positioned above the first roller assembly 420. A sock exit gap is defined between the first and second roller assemblies 420, allowing socks to pass through. The first roller assembly 420 has a sock drop-off area 424 at the rear and a sock exit area 425 at the front. The sock drop-off area 424 is positioned below the sock turning sleeve 300. The projection of the second roller assembly 430 on the first roller assembly 420 at least partially overlaps with the sock exit area 425.

[0073] The second roller assembly 430 is fixed to the fixing frame 412. The second roller assembly 430 can be fixed to the first fixing frame 4121; one end of the second roller assembly 430 can be fixed to the first fixing frame 4121 and the other end can be fixed to the second fixing frame 4122; or another fixing frame can be provided on the bottom plate 411, and the second roller assembly 430 can be fixed to the other fixing frame.

[0074] The transmission assembly 440 may be a pair of gears meshing with each other, or a synchronous belt with two synchronous wheels arranged in an antiparallelogram.

[0075] After the socks fall, they land in the sock landing area 424. The force between the socks and the first roller assembly 420 drives the socks to move forward into the sock exit area 425. By reasonably setting the spacing of the sock exit gap, when the socks pass through the sock exit gap, they are respectively acted upon by the second roller assembly 430 and the first roller assembly 420. Moreover, since the first roller assembly 420 and the second roller assembly 430 at least partially overlap in the sock exit area 425, the force of the first roller assembly 420 and the second roller assembly 430 on the socks is further increased. Even if the socks are hooked on the clamping mechanism 200, they can be easily detached, thereby improving the efficiency of the sock turning machine for removing socks that have not been turned over.

[0076] Among them, the sock outlet gap can be configured to be slightly smaller than the thickness of the socks. In this way, when the socks pass through the sock outlet gap, they are squeezed and compressed by the first roller assembly 420 and the second roller assembly 430, thereby increasing the force between the socks and the first roller assembly 420 and the second roller assembly 430, further improving the force of the sock withdrawal mechanism 400 on the socks, and improving the sock withdrawal efficiency of the sock turning machine for socks that have not been turned over.

[0077] In a preferred embodiment, the transmission assembly 440 includes a first gear 441 and a second gear 442 that mesh with each other. The first gear 441 rotates with the first roller assembly 420 , and the second roller assembly 430 rotates with the second gear 442 .

[0078] In this embodiment, a fixing frame 412 is provided with a receiving groove 443 , and the first gear 441 and the second gear 442 are disposed in the receiving groove 443 .

[0079] The receiving groove 443 may be disposed on the first fixing frame 4121 or on the second fixing frame 4122 .

[0080] In some other embodiments, other fixing frames may be provided on the bottom plate 411 , and the other fixing frames may be provided with a receiving groove 443 or a mounting position, and the first gear 441 and the second gear 442 may be provided in the receiving groove 443 or on the mounting position.

[0081] With such an arrangement, the transmission assembly 440 between the first roller assembly 420 and the second roller assembly 430 is relatively simple, and the gear meshing solution is economical and reliable, which is conducive to reducing the cost of the socks unloading mechanism 400.

[0082] In order to further improve the force of the second roller assembly 430 on the socks, in one embodiment, as shown in FIG. Figures 6 to 8 As shown, the second roller assembly 430 includes a second roller shaft 431 and a plurality of friction portions 434 axially spaced apart from each other on the second roller shaft 431 .

[0083] Since the second roller assembly 430 exerts a force on the socks above it, the gravity of the socks does not act on the second roller assembly 430, so the friction between the two is very small. By axially spaced apart multiple friction parts 434 are provided on the second roller shaft 431, the rotation of the second roller shaft 431 causes the friction parts 434 to contact with the socks to generate friction, thereby driving the socks to move forward, further increasing the force of the second roller assembly 430 on the socks to separate from the sock turning machine, and improving the sock removal effect of the sock turning machine.

[0084] In a preferred embodiment, the friction portion 434 is described as a friction ring sleeved on the second roller shaft 431 .

[0085] In another preferred embodiment, the friction portion 434 is described as a friction block embedded on the second roller shaft 431. A plurality of friction blocks are sequentially and spaced apart on the second roller shaft 431.

[0086] Wherein, the friction ring and the friction block are both made of flexible materials.

[0087] Such a configuration further increases the force exerted by the second roller assembly 430 on the socks and improves the sock-removing effect of the sock-turning machine; and the friction portion 434 is made of a flexible material, which, on the one hand, can increase the friction between the friction portion 434 and the socks, and on the other hand, prevents the friction portion 434 from damaging the socks when the second roller assembly 430 rotates.

[0088] It is understandable that the solution of this embodiment can be coordinated with the first roller assembly 420 with the first blade, or with the first roller assembly 420 with the first belt 423. The solution of this embodiment is more effective when coordinated with the first roller assembly 420 with the first belt 423.

[0089] In order to further improve the force of the second roller assembly 430 on the socks, in another embodiment, as Figures 2 to 4 As shown, the second roller assembly 430 includes a second roller shaft 431, a second driven shaft 432 and a second belt 433. Both ends of the second belt 433 are sleeved on the second roller shaft 431 and the second driven shaft 432. The first roller assembly 420 drives the second roller shaft 431 to rotate through the transmission assembly 440.

[0090] In this embodiment, the length and width of the second belt 433 are both smaller than those of the first belt 423. The second belt 433 is arranged at the front end of the first belt 423 and the front end of the second belt 433 does not exceed the first belt 423. The front end of the first belt 423 is the sock exit area 425, and the rear end of the first belt 423 is the sock drop area 424. The gap between the first belt 423 and the second belt 433 is the sock exit gap.

[0091] In some other embodiments, the length of the second belt 433 may be smaller than that of the first belt 423 , and the width of the second belt 433 may be equal to or approximately equal to that of the first belt 423 .

[0092] In some other embodiments, the front end of the second belt 433 may also extend beyond the first belt 423 .

[0093] By providing the second belt 433 cooperating with the first belt 423 on the second roller assembly 430, the friction between the second roller assembly 430 and the socks is increased, the force of the sock-removing mechanism 400 on the socks is increased, and the sock-removing effect of the sock-turning machine is improved.

[0094] In this embodiment, the second belt 433 preferably has a rough outer surface. This configuration further increases the friction between the second roller assembly 430 and the socks, further increases the force of the sock-removing mechanism 400 on the socks, and further improves the sock-removing effect of the sock-turning machine.

[0095] In order to further enhance the force exerted by the second roller assembly 430 on the socks, in another embodiment, the second roller assembly 430 includes a second roller shaft 431 and a plurality of second blades circumferentially arranged on the second roller shaft 431 , and the second roller shaft 431 rotates to drive the second blades to rotate.

[0096] The second blade is arranged in the same or similar direction as the first blade.

[0097] In this embodiment, the force between the second roller assembly 430 and the socks is a combination of friction and striking force. The falling socks come into contact with the rotating second blade, which drives the socks to move and thus escape from the sock turning machine.

[0098] By providing the second roller shaft 431 and a plurality of second blades circumferentially arranged on the second roller shaft 431, the friction between the socks and the second blades and the striking force of the second blades on the socks increase the force of the sock-removing mechanism 400 on the socks, making it easier for the socks to detach from the sock-turning machine.

[0099] In this embodiment, the second blade is preferably made of a flexible material, wherein the flexible material may be rubber, silicone or plastic.

[0100] This arrangement avoids the second blade being made of too hard a material, which would damage the socks when it comes into contact with the socks. The socks that have left the sock turning machine can continue to be packaged and sold after being turned over again.

[0101] It is understandable that the solution of this embodiment can be coordinated with the first roller assembly 420 with the first blade, or with the first roller assembly 420 with the first belt 423. The solution of this embodiment works better with the first roller assembly 420 with the first blade.

[0102] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art will understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present invention are intended to be included within the scope of the claims.
