Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hanging production lines, in particular to an anti-backward structure and a hanging lifting arm. Background Art
[0002] A hanging production line usually has a hanging lifting arm before the hanger exits the work station. The main function of the lifting arm is to lift and convey the clothes hangers that have completed work at the work station or the bridging station back to the main track of the production line, so that the sewing materials on the clothes hangers can enter the next process for processing;
[0003] However, during the process of the clothes hanger roller entering the bottom of the lifting arm, the back-and-forth swing of the clothes hanger body will cause the clothes hanger roller to move backward. If the lifting arm push block happens to run to prepare to lift the clothes hanger roller at this time, it may cause the clothes hanger roller not to be lifted normally due to the misalignment between the lifting arm push block and the clothes hanger roller, or the lifting arm may be stuck due to the interference between the lifting arm push block and the misaligned clothes hanger roller, and the lifting motor may be blocked. Summary of the Utility Model
[0004] Based on this, in view of the problem that the lifting arm may not be able to lift the clothes hanger roller normally due to the backward movement of the clothes hanger roller during the process of the clothes hanger roller entering the lifting arm, it is necessary to provide an anti-backward structure and a hanging lifting arm in which the clothes hanger roller does not move backward during the process of entering the hanging lifting arm.
[0005] The present application first provides an anti-backward structure, including an entrance track tube and a clothes hanger roller. The clothes hanger roller is clamped on the top of the entrance track tube and can roll along the entrance track tube. The anti-backward structure further includes an anti-backward member. The anti-backward member is arranged on the entrance track tube and has an anti-backward surface. At least part of the anti-backward surface is located above the entrance track tube and corresponds to the clothes hanger roller in the X-axis direction. The anti-backward surface is used to abut against the clothes hanger roller after the clothes hanger roller passes the anti-backward member in the positive X-axis direction, so as to block the clothes hanger roller from rolling in the negative X-axis direction.
[0006] In one embodiment, the anti-backward member is fixed to the top of the entrance track tube. The clothes hanger roller includes a roller shaft and roller discs fixed at both ends of the roller shaft. An annular rolling groove is formed between the two roller discs and the roller shaft. The anti-backward member is fixed to the top of the entrance track tube, and the anti-backward member can be embedded in the rolling groove.
[0007] In one embodiment, a guiding portion is arranged at one end of the anti-backward member in the negative X-axis direction. The width of the guiding portion gradually decreases in the negative X-axis direction, so that the projection of the guiding portion in the Z-axis direction is triangular.
[0008] In one embodiment, the anti-back-off member includes an orbit portion and an anti-back-off portion located at one end of the orbit portion along the positive X-axis direction. The orbit portion is parallel to the X-axis direction, one end of the anti-back-off portion slopes upward along the positive X-axis direction, and the anti-back-off surface is located on the anti-back-off portion.
[0009] In one embodiment, the anti-back-off structure further includes an anti-back-off assembly. The anti-back-off assembly includes the anti-back-off member and an elastic member. The anti-back-off member is hinged to the inlet orbit tube, and the elastic member connects the inlet orbit tube and the anti-back-off member. In the initial state, at least a part of the anti-back-off surface of the anti-back-off member is located above the inlet orbit tube and corresponds to the hanger roller along the X-axis direction.
[0010] In one embodiment, the anti-back-off member is located on the side surface of the inlet orbit tube along the Y-axis direction, and the rotation center line of the anti-back-off member is parallel to the Y-axis direction.
[0011] In one embodiment, the anti-back-off assembly further includes a fixed base. The fixed base is fixed to the bottom of the inlet orbit tube and protrudes from the inlet orbit tube along the Y-axis direction. The anti-back-off member is hinged to the fixed base, and a limiting protrusion is fixedly provided on the anti-back-off member. In the initial state, the anti-back-off member is located in the first quadrant of the XOZ plane with the hinge point as the center, and the limiting protrusion abuts against the fixed base to prevent the anti-back-off member from rotating counterclockwise.
[0012] In one embodiment, a supporting plate is fixed to the bottom of the inlet orbit tube. The supporting plate protrudes from both sides of the inlet orbit tube along the Y-axis direction to support the roller discs on both sides.
[0013] In one embodiment, a feeding adjustment portion is provided at one end of the supporting plate along the negative X-axis direction. One end of the feeding adjustment portion slopes downward along the negative X-axis direction.
[0014] The second aspect of the present application provides a hanging lifting arm, which includes a lifting assembly, a lifting orbit tube, and the above anti-back-off structure. The lifting orbit tube is connected to the end of the inlet orbit tube along the positive X-axis direction. The lifting push block of the lifting assembly is used to rotate along the lifting path to drive the hanger roller to lift along the lifting orbit tube. Among them, the anti-back-off surface is located on the lifting path.
[0015] In the above anti-backward structure, when the blocking point releases the hanger roller to freely slide down along the entrance track tube, the hanger roller can cross the anti-backward part along the positive direction of the X-axis under the action of inertia. At this time, the anti-backward surface can be used to block the hanger roller, thereby preventing the hanger roller from rolling along the negative direction of the X-axis to exceed the anti-backward surface, playing a role in preventing the hanger roller from moving backward, and further avoiding the situation that the lifting arm cannot be normally lifted due to the misalignment or jamming of the hanger roller and the lifting push block when the lifting arm is started.

The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.
[0032] For the convenience of description, in the present application, the length direction of the inlet track tube 10 at the position where the anti-backward member 31 is located is defined as the X-axis direction, and the side close to the lifting device is defined as the positive direction of the X-axis. The length direction of the lifting track tube 60 is defined as the Z-axis direction, and the direction perpendicular to both the X-axis and the Z-axis directions is defined as the Y-axis direction.
[0033] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown, the present application first provides an anti-backward structure, including an inlet track tube 10 and a hanger roller 20. The hanger roller 20 is clamped to the top of the inlet track tube 10 and can roll along the inlet track tube 10. The anti-backward structure further includes an anti-backward member 31. The anti-backward member 31 is disposed on the inlet track tube 10 and has an anti-backward surface 31a. At least a part of the anti-backward surface 31a is located on the upper side of the inlet track tube 10 and corresponds to the hanger roller 20 in the X-axis direction. The anti-backward surface 31a is used to abut against the hanger roller 20 after the hanger roller 20 passes the anti-backward member 31 in the positive X-axis direction, so as to block the hanger roller from rolling in the negative X-axis direction.
[0034] In the present application, when the blocking point releases the hanger roller 20 to freely slide down along the inlet track tube 10, the hanger roller 20 can cross the anti-backward member 31 in the positive X-axis direction under the action of inertia. At this time, the anti-backward surface 31a can be used to block the hanger roller 20, thereby preventing the hanger roller 20 from rolling in the negative X-axis direction to exceed the anti-backward surface 31a, playing a role in preventing the hanger roller 20 from moving backward, and further avoiding the situation that the lifting arm cannot be normally lifted due to the dislocation or jamming of the hanger roller 20 and the lifting push block when the lifting arm starts.
[0035] It should be noted that since the anti-retreat surface 31a is located on the lifting path of the lifting push block 51, as long as the swinging amplitude of the hanger roller 20 back and forth does not exceed the anti-retreat surface 31a, it can be ensured that the lifting push block 51 can normally push the hanger roller 20 to complete the lifting along the entrance track tube 10 and the lifting track tube 60.
[0036] Specifically, the anti-retreat member 31 can be fixed to the entrance track tube 10 or hinged to the entrance track tube 10. The present application does not limit the connection method and connection position of the anti-retreat member 31, as long as the anti-retreat surface 31a of the anti-retreat member 31 can block the hanger roller to prevent it from retreating in the negative X-axis direction.
[0037] Please refer to Figure 2 and Figure 3 As shown, in some embodiments, the hanger roller 20 includes a roller shaft 21 and roller discs 22 fixed to both ends of the roller shaft 21. An annular rolling groove 23 is formed between the two roller discs 22 and the roller shaft 21; the anti-retreat member 31 is fixed to the top of the entrance track tube 10, and the anti-retreat member 31 can be embedded in the rolling groove 23.
[0038] After the blocking point releases the hanger roller 20, the roller shaft 21 rolls along the entrance track tube 10 to the upper side of the anti-retreat member 31 and rolls along the anti-retreat member 31 in the positive X-axis direction under the action of inertia to cross the anti-retreat member 31.
[0039] Since the anti-retreat member 31 can be embedded in the rolling groove 23, during the rolling process of the hanger roller 20, the two side surfaces of the anti-retreat member 31 in the Y-axis direction can abut against the inner side surfaces of the two roller discs 22 to realize the limit of the hanger roller 20 in the Y-axis direction, so as to avoid the situation that the hanger roller 20 tilts in the Y-axis direction due to a heavier load on one side of the hanger, resulting in the hanger roller 20 being unable to enter the lifting arm.
[0040] Preferably, the anti-retreat member 31 is made of plastic and fixed to the entrance track tube 10 by screws.
[0041] Please refer to Figure 2 and Figure 3 As shown, in some embodiments, a guiding portion 311 is provided at one end of the anti-retreat member 31 in the negative X-axis direction. The width of the guiding portion 311 gradually decreases in the negative X-axis direction, so that the projection of the guiding portion 311 in the Z-axis direction is triangular. The triangular guiding portion 311 can play a guiding and positioning effect in the Y-axis direction to prevent the hanger roller 20 from tilting and shifting in the Y-axis direction during the process of rolling onto the anti-retreat member 31.
[0042] Preferably, the thickness of the guiding part 311 also gradually decreases along the negative X-axis direction, so as to facilitate the rolling of the hanger roller 20 onto the anti-backward part 31.
[0043] Please refer to Figure 4 As shown, in some embodiments, the anti-backward part 31 includes a track part 312 and an anti-backward part 313 located at one end of the track part 312 along the positive X-axis direction. The track part 312 is parallel to the X-axis direction. One end of the anti-backward part 313 along the positive X-axis direction slopes upward, and the anti-backward surface 31a is located on the anti-backward part 313; the upward-sloping anti-backward part 313 can increase the height of the anti-backward surface 31a, thereby increasing the blocking effect of the anti-backward surface 31a on the hanger roller 20, preventing the situation where the hanger roller 20 swings along the negative X-axis direction and crosses the anti-backward surface 31a, and improving the anti-backward reliability of the present application.
[0044] Please combine Figure 5 and Figure 6 As shown, in some embodiments, the anti-backward structure further includes an anti-backward assembly 30. The anti-backward assembly 30 includes an anti-backward part 31 and an elastic part 32. The anti-backward part 31 is hinged to the entrance track tube 10, and the elastic part 32 connects the entrance track tube 10 and the anti-backward part 31; in the initial state, at least part of the anti-backward surface 31a of the anti-backward part 31 is located above the entrance track tube 10 and corresponds to the hanger roller 20 in the X-axis direction.
[0045] During the process that the hanger roller 20 rolls past the anti-backward part 31, the hanger roller 20 will overcome the elastic force of the elastic part 32 and squeeze the anti-backward part 31. When the hanger roller 20 passes the anti-backward part 31, the anti-backward part 31 reversely resets under the action of the elastic force of the elastic part 32.
[0046] Please combine Figure 5 and Figure 6 As shown, in some embodiments, the anti-backward part 31 is located on the side surface of the entrance track tube 10 along the Y-axis direction, and the rotation center line of the anti-backward part 31 is parallel to the Y-axis direction.
[0047] It is not difficult to understand that the anti-backward part 31 is hinged to the entrance track tube 10 along the Y-axis direction. Compared with the scheme that the anti-backward part 31 is directly fixed to the entrance track tube 10, the height of the anti-backward surface 31a of the latter cannot be too high, otherwise it may cause the situation that the hanger roller 20 cannot cross the anti-backward part 31 due to insufficient inertia of the hanger roller 20;
[0048] However, in the former case, since the anti-backward part 31 can rotate around the Y-axis direction and the anti-backward part 31 can reversely reset after the hanger roller 20 passes, the height of the anti-backward surface 31a can be designed higher than that of the latter to obtain a more reliable anti-backward effect.
[0049] Please combine Figure 6 、 Figure 7as well as Figure 8 As shown, in some embodiments, the anti-backoff assembly also includes a fixed base, which is fixed to the bottom of the inlet track tube 10 and protrudes from the inlet track tube 10 along the Y-axis direction. The anti-backoff member 31 is hinged to the fixed base, and a limiting protrusion 31b is also fixed on the anti-backoff member 31. In the initial state, the anti-backoff member 31 is located in the first quadrant of the XOZ plane centered on the hinge point, and the limiting protrusion 31b is abutted against the fixed base to prevent the anti-backoff member 31 from rotating counterclockwise to determine the initial position of the anti-backoff member 31.
[0050] Specifically, a rotating pin along the Y-axis direction is fixed on the fixed base, and the anti-backoff member 31 is rotatably connected to the rotating pin. A fixed shaft along the Y-axis direction is also fixed on the fixed base, one end of the elastic member 32 is connected to the fixed shaft, and the other end is clamped with the anti-backoff member 31.
[0051] Preferably, two anti-retraction members 31 are provided on both sides of the inlet track tube 10 along the Y-axis direction to increase the anti-retraction stability.
[0052] In some embodiments, the fixed base is a part of the supporting plate 40; of course, in some other embodiments, the fixed base may also be an independent part, and the present application does not make further limitations here.
[0053] It should be noted that when a heavier piece is mounted on the hanger, the hanger tends to tilt to one side, thereby causing the hanger roller 20 to tilt. After the hanger roller 20 tilts, it may interfere with the outer shell of the lifting component 50, thereby causing the hanger roller 20 to be unable to enter the lifting path of the lifting component 50.
[0054] In this regard, please combine Figure 2 as well as Figure 3 As shown, in some embodiments, a supporting plate 40 is fixed to the bottom of the inlet track tube 10 , and the supporting plate 40 protrudes from both sides of the inlet track tube 10 along the Y-axis direction to support the roller plates 22 on both sides.
[0055] The support plate 40 has the same height on both sides along the Y-axis direction, and is used to support the roller plates 22 on both sides to ensure that the roller plates 22 on both sides of the hanger roller 20 are straightened without tilting along the Y-axis direction, thereby ensuring that the hanger roller 20 can enter the lifting path of the lifting assembly 50 along the inlet track tube 10.
[0056] Please combine Figure 2 as well as Figure 3 As shown, in some embodiments, a feeding adjustment portion 41 is provided at one end of the supporting plate 40 along the negative direction of the X-axis, and the feeding adjustment portion 41 is inclined downward at one end along the negative direction of the X-axis.
[0057] The feeding adjustment part 41 can play a guiding and adjusting role for the roller disc 22. When the hanger roller 20 is tilted, one side of the roller disc 22 will tilt downward. By setting the feeding adjustment part 41, as the hanger roller 20 advances along the entrance track pipe 10, the downward-tilted roller disc 22 will first contact the feeding adjustment part 41 and gradually straighten under the support of the feeding adjustment part 41.
[0058] Please refer to Figure 9 As shown, the second aspect of the present application provides a hanging lifting arm, including a lifting component 50, a lifting track pipe 60, and the above anti-backward structure. The lifting track pipe 60 is connected to the end of the entrance track pipe 10 along the positive X-axis direction. The lifting push block 51 of the lifting component 50 is used to rotate along the lifting path to drive the hanger roller 20 to lift along the lifting track pipe 60. Among them, the anti-backward surface 31a is located on the lifting path.
[0059] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0060] The above embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
