Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of garment production lines, in particular to an anti-overrun structure at the outlet and a hanging lifting arm. Background Art
[0002] A hanging production line usually has a hanging lifting arm before the hanger exit station. The main function of the lifting arm is to lift the hanger on which the work at the workstation or the bridging station is completed and convey it back to the main track of the production line, so that the sewing material on the hanger can enter the next process for processing.
[0003] The lifting push block in the lifting arm rotates cyclically under the drive of the motor to lift the hanger roller entering the bottom of the lifting arm through the lifting arm inlet to the lifting arm outlet at the top. Normally, when the lifting push block reaches the outlet position, the lifting push block will stop lifting, and the hanger roller will roll forward under the action of gravity and enter the exit station.
[0004] However, when the lifting push block overshoots without accurately stopping at the outlet position, it will drive the hanger roller to overshoot together and cause the hanger roller to interfere and jam with the C-shaped pipe or other structures of the lifting arm, resulting in the hanger roller being unable to leave the station normally. Summary of the Utility Model
[0005] Based on this, in view of the problem that the hanger roller currently overshoots at the outlet position of the hanging lifting arm, it is necessary to provide an anti-overrun structure at the outlet and a hanging lifting arm that are not prone to overrun.
[0006] This application first provides an anti-overrun structure at the outlet, including a housing, a lifting assembly, a track pipe, and a hanger roller. The track pipe includes a lifting pipe and a discharge pipe fixed to the top of the lifting pipe. A lifting track is formed between the housing and the lifting pipe. The upper side of the discharge pipe is a discharge track. The lifting assembly is arranged inside the housing and is used to lift the hanger roller along the lifting track. An anti-overrun member is also arranged on the housing and / or the track pipe. The anti-overrun member corresponds to the discharge track and at least partially protrudes from the lifting track. One end of the anti-overrun member faces the discharge track to block the hanger roller rising along the lifting track and guide it to the discharge track.
[0007] In one embodiment, the anti-overrun member is fixed relative to the housing and / or the track pipe.
[0008] In one embodiment, a C-shaped pipe is fixed on the discharge pipe. The anti-overrun member has a guiding surface for abutting against the hanger roller. The height of the end of the guiding surface close to the C-shaped pipe along the Z-axis direction is less than or equal to the height of the upper inner wall of the C-shaped pipe.
[0009] In one embodiment, the guiding surface is arc-shaped and spans the lifting track in the X-axis direction.
[0010] In one embodiment, an anti-backward member is also fixed to one end of the discharge pipe close to the lifting track.
[0011] In one embodiment, the anti-overrun member is hinged to the housing, and a limit pin for abutting against the anti-overrun member is also fixed to the housing to limit the anti-overrun member between an initial state and an avoidance state;
[0012] In the initial state, the anti-overrun member blocks the lifting track in the Z-axis direction; in the avoidance state, an opening communicating with the discharge track is formed between the anti-overrun member and the discharge pipe, and the anti-overrun member is used to guide the hanger roller through the opening to the discharge track.
[0013] In one embodiment, in the avoidance state, the length direction of the anti-overrun member is between the positive X-axis direction and the positive Z-axis direction.
[0014] In one embodiment, an elastic reset member is also connected between the anti-overrun member and the housing to drive the anti-overrun member to return to the initial state.
[0015] In one embodiment, the anti-overrun member includes an anti-overrun rod and a check rod. One end of the anti-overrun rod is hinged to the housing, and the check rod is fixed to the other end of the anti-overrun rod;
[0016] In the initial state, the anti-overrun rod blocks the lifting track in the Z-axis direction, and the check rod blocks the discharge track in the X-axis direction.
[0017] The second aspect of the present application provides a hanging lifting arm, including the above-mentioned outlet anti-overrun structure.
[0018] The above-mentioned outlet anti-overrun structure is provided with an anti-overrun member corresponding to the discharge track and at least partially protruding from the lifting track, so that when the lifting assembly drives the hanger roller to rise along the lifting track to the outlet position, the anti-overrun member can block the hanger roller and limit its further rise to avoid the situation of interference with other parts caused by the overrun of the hanger roller; in addition, one end of the anti-overrun member faces the discharge track, and the extrusion force between the hanger roller and the anti-overrun member can drive the hanger roller to leave the lifting track in the X-axis direction and enter the discharge track.

[0033] For the convenience of description, in this application, the length direction of the lifting track 50 is defined as the Z-axis direction, the length direction of the discharging track 60 is defined as the X-axis direction, and the direction perpendicular to the XOZ plane is defined as the Y-axis direction. Among them, the lifting direction of the lifting track 50 is the positive direction of the Z-axis, and the discharging direction of the hanger roller 40 along the discharging track 60 is the positive direction of the X-axis.
[0034] Please refer to Figure 1 and Figure 2 As shown, this application first provides an anti-overrun structure at the outlet, including a housing 10, a lifting assembly 20, a track tube 30 and a hanger roller 40. The track tube 30 includes a lifting tube 31 and a discharging tube 32 fixed to the top of the lifting tube 31. A lifting track 50 is formed between the housing 10 and the lifting tube 31. The upper side of the discharging tube 32 is the discharging track 60. The lifting assembly 20 is disposed inside the housing 10 and is used to lift the hanger roller 40 along the lifting track 50; an anti-overrun member 70 is also provided on the housing 10 and / or the track tube 30. The anti-overrun member 70 corresponds to the discharging track 60 and at least partially protrudes from the lifting track 50. One end of the anti-overrun member 70 faces the discharging track 60 to block the hanger roller 40 rising along the lifting track 50 and guide it to the discharging track 60.
[0035] In this application, by providing the anti-overrun member 70 corresponding to the discharging track 60 and at least partially protruding from the lifting track 50, when the lifting assembly 20 drives the hanger roller 40 to rise along the lifting track 50 to the outlet position, the anti-overrun member 70 can block the hanger roller 40 and limit its further rise to avoid the situation of interference with other parts caused by the overrun of the hanger roller 40; in addition, one end of the anti-overrun member 70 faces the discharging track 60, and the extrusion force between the hanger roller 40 and the anti-overrun member 70 can drive the hanger roller 40 to leave the lifting track 50 along the X-axis direction and enter the discharging track 60.
[0036] Specifically, the anti-overrun member 70 has a guiding surface 70a for abutting against the hanger roller 40, and the guiding surface 70a abuts against the part of the hanger roller 40 located in the second quadrant. Here, the second quadrant refers to the second quadrant of the XOZ coordinate system with the axis of the hanger roller 40 as the origin;
[0037] Set as such that after the lifting component 20 drives the hanger roller 40 to be lifted until it abuts against the anti-overrun member 70, the reaction force of the anti-overrun member 70 on the hanger roller 40 can be decomposed into a component force along the negative Z-axis direction and a component force along the positive X-axis direction. Among them, the component force along the negative Z-axis direction is used to block the continuous lifting of the hanger roller 40, and the component force along the positive X-axis direction can drive the hanger roller 40 to leave the lifting track 50 and enter the discharge track 60, so as to achieve the effects of preventing the hanger roller 40 from overshooting and guiding it to roll to the discharge track 60 through the anti-overrun member 70.
[0038] Please refer to Figure 1 and Figure 2 As shown, in some embodiments, the anti-overrun member 70 is fixed relative to the housing 10 and / or the track tube 30.
[0039] Specifically, a C-shaped tube 321 is fixed on the discharge tube 32. A discharge track 60 is formed between the C-shaped tube 321 and the discharge tube 32, and the anti-overrun member 70 is fixed to the C-shaped tube 321.
[0040] More specifically, a waist-shaped hole is formed in the anti-overrun member 70 along the Z-axis direction. The anti-overrun member 70 is fixed to the C-shaped tube 321 through a screw passing through the waist-shaped hole, so that the position of the anti-overrun member 70 along the Z-axis direction can be adjusted according to requirements.
[0041] Please refer to Figure 1 and Figure 2 As shown, in some embodiments, the height of the end of the guiding surface 70a close to the C-shaped tube 321 along the Z-axis direction is less than or equal to the height of the upper inner wall of the C-shaped tube 321, so as to prevent the situation that the hanger roller 40 overshoots and gets stuck in interference with the C-shaped tube 321.
[0042] Please refer to Figure 1 and Figure 2 As shown, in some embodiments, the guiding surface 70a is arc-shaped, and the guiding surface 70a spans the lifting track 50 along the X-axis direction.
[0043] Of course, in some other embodiments, the guiding surface 70a can also be an inclined surface or other shapes, as long as it can achieve the effects of blocking and guiding. Examples are not given one by one in this application.
[0044] Please refer to Figure 1 and Figure 2 As shown, in some embodiments, an anti-backward member 322 is further fixed to the end of the discharge tube 32 close to the lifting track 50; the hanger roller 40 on the discharge track 60 may move backward under the swing of the hanger body, and the anti-backward member 322 can block the hanger roller 40 moving backward along the negative X-axis direction on the discharge track 60, so as to avoid the situation that the hanger roller 40 moves back to the lifting track 50 and drops.
[0045] It is worth mentioning that compared with the solution in which the anti-return piece 322 is arranged at the discharge pipe 32 near the discharge position, the anti-return piece 322 is close to the discharge position where the hanger roller 40 stops. Therefore, a slight shaking of the hanger body will drive the hanger roller 40 to swing and contact the anti-return piece 322. On the one hand, the hanger roller 40 frequently hits the anti-return piece 322, which will affect the service life of the anti-return piece 322. On the other hand, the swing amplitude of the hanger roller 40 is large, and the impact force on the anti-return piece 322 is strong, which will also affect the service life of the anti-return piece 322.
[0046] In the present application, since the anti-retraction part 322 is located at one end close to the lifting track 50, the hanger roller 40 that stays at the discharge position will only contact the anti-retraction part 322 when it swings significantly (swings along the negative direction of the X-axis to a position close to the exit of the lifting track 50). On the one hand, the contact frequency is low, which can increase the service life of the anti-retraction part 322. On the other hand, when the hanger roller 40 swings to contact the anti-retraction part 322, most of its kinetic energy has been converted into gravitational potential energy, that is, at this time, the impact force with the anti-retraction part 322 is relatively small, which can also increase the service life of the anti-retraction part 322.
[0047] Please combine Figure 3 as well as Figure 4 As shown, in some embodiments, the over-punch prevention member 70 is hinged to the housing 10, and the housing 10 is also provided with a limit pin 11 for abutting against the over-punch prevention member 70, so as to limit the over-punch prevention member 70 between the initial state and the avoidance state;
[0048] In the initial state, the anti-overshoot component 70 blocks the lifting track 50 along the Z-axis direction; in the avoidance state, an opening connected to the discharge track 60 is formed between the anti-overshoot component 70 and the discharge pipe 32, and the anti-overshoot component 70 is used to guide the hanger roller 40 to the discharge track 60 through the opening.
[0049] The anti-overshoot component 70 in the initial state can block the hanger roller 40 and play a buffering role when the hanger roller 40 rises along the lifting track 50, so as to avoid overshoot caused by the excessive speed of the hanger roller 40. In addition, since the anti-overshoot component 70 is hinged to the shell 10, the anti-overshoot component 70 can be rotated to the avoidance state after completing the buffering of the hanger roller 40 to release the hanger roller 40, ensuring that the hanger roller 40 can leave the lifting track 50 normally. After the release is completed, the anti-overshoot component 70 returns to the initial state to block and prevent the hanger roller 40 from retreating to the lifting track 50. The exit limit structure of the present application can simultaneously solve the two problems of overshoot and retreat of the hanger roller 40 at the exit position of the lifting track 50 by relying on only one anti-overshoot component 70.
[0050] Specifically, a first limit protrusion 711 and a second limit protrusion 712 are fixed on the overshoot prevention member 70. In the initial state, the first limit protrusion 711 abuts against the limit pin 11 to limit the rotation of the overshoot prevention member 70 in the negative Z-axis direction, so as to prevent the situation that the overshoot prevention member 70 rotates in the negative Z-axis direction and causes the blocking failure when the hanger roller 40 swings back and squeezes the check rod 72, thereby increasing the check safety.
[0051] In the avoidance state, the second limit protrusion 712 abuts against the limit pin 11 to limit the rotation of the overshoot prevention member 70 in the positive Z-axis direction.
[0052] More specifically, an overshoot prevention member 70 is hinged on each of the two sides of the housing 10 in the Y-axis direction to increase the contact stability between the overshoot prevention member 70 and the hanger roller 40 and avoid the situation that the hanger roller 40 deflects in the Y-axis direction.
[0053] In some embodiments, a rotating shaft 90 is rotatably connected to the housing 10. The rotating shaft 90 penetrates the housing 10 in the Y-axis direction, and the two overshoot prevention members 70 are both fixed to the rotating shaft 90, so that the two overshoot prevention members 70 can rotate synchronously, further improving the contact stability between the overshoot prevention member 70 and the hanger roller 40 and avoiding the situation that the hanger roller 40 deflects due to uneven contact.
[0054] It should be noted that the two states of the overshoot prevention member 70 can be actively switched or passively switched. As long as the overshoot prevention member 70 can be switched to the avoidance state after the hanger roller 40 is lifted to the exit position of the lifting track 50 and restored to the initial state after the hanger roller 40 passes through the exit position, this application does not make further limitations here.
[0055] Taking the active switching as an example: A sensor can be set at the exit position of the lifting track 50, a driving member can be set for the overshoot prevention member 70, and the sensor is electrically connected to the driving member. When the sensor detects the hanger roller 40, the driving member is controlled to start and drive the overshoot prevention member 70 to switch to the avoidance state. After the hanger roller 40 passes through the exit position, the driving member drives the overshoot prevention member 70 back to the initial state.
[0056] Taking the passive switching as an example: When the overshoot prevention member 70 is hinged or slidably connected to the housing 10 and / or the track tube 30, after the hanger roller 40 is lifted to contact the overshoot prevention member 70, the overshoot prevention member 70 will be switched to the avoidance state under the extrusion force of the hanger roller 40 and restored to the initial state after the hanger roller 40 passes through the exit position. The overshoot prevention member 70 can be restored by an elastic member or by its own gravity, and this application also does not make limitations here.
[0057] Please combine Figure 3 and Figure 5As shown, in some embodiments, in the avoidance state, the length direction of the overshoot prevention member 70 is between the positive X-axis direction and the positive Z-axis direction.
[0058] With such a setting, when the lifting assembly 20 drives the hanger roller 40 to rise until it abuts against the overshoot prevention member 70, the overshoot prevention member 70 abuts against the second quadrant part of the hanger roller 40, so that the overshoot prevention member 70 has a component force in the positive X-axis direction on the hanger roller 40, thereby achieving the effect of assisting the hanger roller 40 to leave the lifting track 50.
[0059] Please refer to Figure 2 , Figure 6 and Figure 7 As shown, in some embodiments, an elastic reset member 80 is further connected between the overshoot prevention member 70 and the housing 10, and is used to drive the overshoot prevention member 70 to return to its initial state.
[0060] When the overshoot prevention member 70 is in the avoidance state, that is, when the hanger roller 40 rises to correspond to the outlet position of the lifting track 50 along the X-axis direction, the overshoot prevention member 70 presses the hanger roller 40 under the elastic action of the elastic reset member 80, and this pressing force is bound to have a component force in the positive X-axis direction to drive the hanger roller 40 to smoothly disengage from the lifting track 50 along the positive X-axis direction, and can also achieve the effect of assisting the hanger roller 40 to leave the lifting track 50.
[0061] Specifically, the elastic reset member 80 is a torsion spring, one end of the torsion spring is connected to the rotating shaft 90, and the other end is connected to the housing 10.
[0062] Please refer to Figure 4 and Figure 7 As shown, in some embodiments, the overshoot prevention member 70 includes an overshoot prevention rod 71 and a check rod 72. One end of the overshoot prevention rod 71 is hinged to the housing 10, and the check rod 72 is fixed to the other end of the overshoot prevention rod 71; in the initial state, the overshoot prevention rod 71 blocks the lifting track 50 along the Z-axis direction, and the check rod 72 blocks the discharging track 60 along the X-axis direction.
[0063] When the hanger roller 40 rises along the lifting track 50, it will contact the overshoot prevention rod 71 located in the lifting track 50. The hanger roller 40 overcomes the elastic force of the elastic reset member 80 and presses the overshoot prevention rod 71, so that the kinetic energy of the hanger roller 40 is converted into the elastic potential energy of the elastic reset member 80, and the overshoot prevention rod 71 is used to prevent the hanger roller 40 from overshooting.
[0064] When the hanger roller 40 leaves the lifting track 50 and no longer contacts the anti-overrun member 70, the anti-overrun member 70 returns to its initial state under the action of the elastic reset member 80. At this time, the check rod 72 protrudes from the discharge pipe 32 in the Z-axis direction. Therefore, when the hanger roller 40 swings along the discharge track 60, it can block the hanger roller 40 to prevent it from retreating to the lifting track 50.
[0065] The second aspect of the present application provides a hanging lifting arm, including the above-mentioned outlet anti-overrun structure.
[0066] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.
[0067] The above-described embodiments only represent several implementation manners of the present utility model, and the description is relatively specific and detailed. However, it should not be construed as a limitation on 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 shall be subject to the appended claims.
