Description

Technical Field

[0001] The utility model relates to the technical field of garment production lines, in particular to a discharging guiding and assisting structure 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 top lifting arm outlet. Normally, when the lifting push block reaches the outlet position, the lifting push block will stop lifting, and the hanger roller rolls forward under the action of gravity and enters the exit station;

[0004] However, the discharging process relying only on its own weight has poor stability, and it is easy to occur that after the lifting push block reaches the outlet position, the hanger roller gets stuck on the lifting push block and does not enter the discharging track. Summary of the Utility Model

[0005] Based on this, in view of the problem that the discharging stability of the current hanger roller is poor and it is easy to get stuck on the lifting push block, it is necessary to provide a discharging guiding and assisting structure and a hanging lifting arm that can assist the hanger roller to break away from the lifting push block and enter the discharging track.

[0006] This application first provides a discharging guiding and assisting structure, including a housing, a lifting assembly, a track pipe, and a hanger roller. The track pipe includes a lifting pipe and a discharging pipe fixed to the top end of the lifting pipe. A lifting track is formed between the housing and the lifting pipe. The upper side of the discharging pipe is a discharging track. The lifting assembly is arranged inside the housing and is used to lift the hanger roller along the lifting track.

[0007] A guiding and assisting member is hinged to the housing, and a limiting pin for abutting against the guiding and assisting member is also fixed to the housing to limit the guiding and assisting member between the initial state and the guiding state. An elastic reset member is also connected between the guiding and assisting member and the housing to drive the guiding and assisting member to return to the initial state;

[0008] In the initial state, at least a part of the guiding and assisting member protrudes from the lifting track;

[0009] In the guiding state, the length direction of the guiding and assisting member is between the positive X-axis direction and the positive Z-axis direction, and an opening communicating with the discharging track is formed between the guiding and assisting member and the discharging pipe.

[0010] In one embodiment, in the guiding state, the included angle range between the length direction of the guiding assisting member and the positive direction of the Z-axis is ° to °.

[0011] In one embodiment, a C-shaped pipe is fixed on the discharge pipe. The guiding assisting member has a guiding surface for abutting against the hanger roller. In the guiding state, 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.

[0012] In one embodiment, the guiding assisting 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.

[0013] In the initial state, the anti-overrun rod blocks the lifting track along the Z-axis direction, and the check rod blocks the discharge track along the X-axis direction.

[0014] In one embodiment, in the initial state, the anti-overrun rod spans across the lifting track along the X-axis direction, and at least part of the anti-overrun rod corresponds to the discharge pipe along the Y-axis direction.

[0015] In one embodiment, a first limiting protrusion is fixed on the anti-overrun rod.

[0016] In the initial state, the first limiting protrusion abuts against the limiting pin to limit the guiding assisting member from rotating in the negative direction of the Z-axis.

[0017] In one embodiment, a second limiting protrusion is fixed on the anti-overrun rod.

[0018] In the guiding state, the second limiting protrusion abuts against the limiting pin to limit the guiding assisting member from rotating in the positive direction of the Z-axis.

[0019] In one embodiment, one guiding assisting member is hinged on each of the two sides of the housing along the Y-axis direction.

[0020] In one embodiment, a rotating shaft is rotatably connected to the housing. The rotating shaft penetrates through the housing along the Y-axis direction, and both guiding assisting members are fixed to the rotating shaft.

[0021] The second aspect of the present application provides a hanging lifting arm, including the above-mentioned discharge guiding assisting structure.

[0022] The above-mentioned discharging guiding and assisting structure is configured by hinging a guiding and assisting member on a housing and connecting an elastic reset member therebetween, so that the elastic reset member can convert the kinetic energy of the hanger roller into its own elastic potential energy, and after the hanger roller is lifted to the exit position of the lifting track, the elastic potential energy is released to drive the guiding and assisting member to squeeze the hanger roller, so as to achieve the effect of assisting the hanger roller to disengage from the lifting track.

[0035] For the convenience of description, in this application, the length direction of the lifting rail 50 is defined as the Z-axis direction, the length direction of the discharge rail 60 is defined as the X-axis direction, and the direction perpendicular to the XOZ plane is defined as the Y-axis direction, wherein the lifting direction of the lifting rail 50 is the positive direction of the Z-axis, and the discharge direction of the hanger roller 40 along the discharge rail 60 is the positive direction of the X-axis.

[0036] Please combine Figures 1 to 4 As shown, the present application first provides a discharging guide assisting structure, including a shell 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 shell 10 and the lifting tube 31, and the upper side of the discharging tube 32 is a discharging track 60, the lifting assembly 20 is arranged inside the shell 10 and is used to lift the hanger roller 40 along the lifting track 50, the shell 10 is hinged with a guide assisting member 70, and the shell 10 is also fixed with a A limit pin 11 is abutted against the guide assisting member 70 to limit the guide assisting member 70 between the initial state and the guiding state. An elastic reset member 80 is also connected between the guide assisting member 70 and the shell 10 to drive the guide assisting member 70 to restore the initial state. In the initial state, the guide assisting member 70 at least partially protrudes from the lifting track 50. In the guiding state, the length direction of the guide assisting member 70 is located between the positive direction of the X-axis and the positive direction of the Z-axis, and an opening connected to the discharge track 60 is formed between the guide assisting member 70 and the discharge pipe 32.

[0037] In the present application, a guide assisting member 70 is hinged on the shell 10, and an elastic reset member 80 is connected between the two, so that the elastic reset member 80 can convert the kinetic energy of the hanger roller 40 into its own elastic potential energy, and after the hanger roller 40 is lifted to the exit position of the lifting track 50, the elastic potential energy is released to drive the guide assisting member 70 to squeeze the hanger roller 40, so as to achieve the effect of assisting the hanger roller 40 to leave the lifting track 50.

[0038] Specifically, after the lifting component 20 drives the hanger roller 40 to contact the guiding and assisting component 70 in the initial state, the hanger roller 40 can drive the guiding and assisting component 70 to rotate against the elastic force of the elastic resetting component 80, that is, convert the kinetic energy of the hanger roller 40 into the elastic potential energy of the elastic resetting component 80; when the guiding and assisting component 70 rotates to the guiding state, the lifting component 20 stops working and the hanger roller 40 no longer rises, and the elastic resetting component 80 releases the elastic potential energy and drives the guiding and assisting component 70 to reverse, thereby driving the hanger roller 40 to leave the lifting track 50 from the opening between the guiding and assisting component 70 and the discharge pipe 32.

[0039] It is worth mentioning that in this application, in the guiding state, the length direction of the guiding and assisting component 70 is between the positive X-axis direction and the positive Z-axis direction. At this time, the guiding and assisting component 70 abuts against the part of the hanger roller 40 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;

[0040] With such a setting, on the one hand, after the lifting component 20 drives the hanger roller 40 to be lifted until it abuts against the guiding and assisting component 70, the reaction force of the guiding and assisting component 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 assist the hanger roller 40 to leave the lifting track 50 through the guiding and assisting component 70;

[0041] On the other hand, when the lifting component 20 drives the hanger roller 40 to be lifted, the hanger roller 40 has an upward extrusion force on the guiding and assisting component 70, and after the extrusion force is orthogonally decomposed, there is also a component force along the positive X-axis direction, which can also assist the hanger roller 40 to leave the lifting track 50.

[0042] In addition, most of the current hanging lifting arms are such that the lifting push block rotates cyclically under the drive of the motor to lift the hanger roller 40 entering the bottom of the lifting arm through the lifting arm inlet to the top lifting arm outlet. Normally, when the lifting push block is lifted to the outlet position, the lifting push block will stop lifting, and the hanger roller 40 rolls forward under the action of gravity and enters the out-station position;

[0043] However, when the lifting push block overshoots without accurately stopping at the outlet position, it will drive the hanger roller 40 to overshoot together and cause the hanger roller 40 to interfere and jam with the C-shaped pipe or other structures of the lifting arm, resulting in the hanger roller 40 being unable to leave the station normally.

[0044] In this application, since the guiding and assisting member 70 at least partially protrudes from the lifting track 50 in the initial state, the guiding and assisting member 70 can also play the role of buffering and blocking the hanger roller 40. Only by the guiding and assisting member 70 can the two effects of preventing the hanger roller 40 from overshooting and assisting it to leave the lifting track 50 be achieved.

[0045] Of course, the two states of the guiding and assisting member 70 can also be actively switched. For example, a sensor can be set at the outlet position of the lifting track 50, a driving member can be set for the guiding and assisting 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 guiding and assisting member 70 to switch to the guiding state. After the hanger roller 40 passes through the outlet position, the driving member drives the guiding and assisting member 70 back to the initial state, thereby driving the hanger roller 40 to leave the lifting track 50.

[0046] In some embodiments, in the guiding state, the included angle range between the length direction of the guiding and assisting member 70 and the positive direction of the Z-axis is 10° to 15°. If the included angle is too small, the guiding and assisting member 70 cannot block the upward movement of the hanger roller 40, and there is a possibility that the hanger roller 40 overshoots. On the contrary, if the included angle is too large, the rotation angle of the guiding and assisting member 70 from the initial state to the guiding state is small, and the elastic potential energy accumulated by the elastic reset member 80 is less, and the assisting effect on the hanger roller 40 is poor. By controlling the included angle range within 10° to 15°, the assisting effect of the hanger roller 40 discharging can be improved as much as possible on the premise of avoiding the overshoot of the hanger roller 40.

[0047] Please refer to Figure 1 and Figure 5 As shown, in some embodiments, a C-shaped pipe 321 is fixed on the discharge pipe 32. A discharge track 60 is formed between the C-shaped pipe 321 and the discharge pipe 32. The guiding and assisting member 70 has a guiding surface 70a for abutting against the hanger roller 40. In the guiding state, the height of the end of the guiding surface 70a close to the C-shaped pipe 321 along the Z-axis direction is less than or equal to the height of the upper inner wall of the C-shaped pipe 321, so that the hanger roller 40 can enter the discharge track 60 under the guidance of the guiding and assisting member 70, and the situation where the hanger roller 40 overshoots and interferes with and jams the C-shaped pipe 321 is avoided.

[0048] Please refer to Figure 3 、 Figure 4 and Figure 5 As shown, in some embodiments, the guiding and assisting 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.

[0049] 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 discharge track 60 along the X-axis direction.

[0050] When the hanger roller 40 leaves the lifting track 50 and no longer contacts the guide assisting member 70, the guide assisting member 70 returns to its original state under the action of the elastic reset member 80. At this time, the hanger roller 40 on the discharge track 60 may retreat under the swing of the hanger body. In the initial state of the present application, the check rod 72 protrudes from the discharge pipe 32 along the Z-axis direction. Therefore, it can block the hanger roller 40 when the hanger roller 40 swings along the discharge track 60 to prevent it from retreating to the lifting track 50.

[0051] In some embodiments, in the initial state, the check rod 72 is located on the side of the discharge track 60 close to the lifting track 50;

[0052] Such arrangement is compared with the scheme of setting the check rod 72 at the discharge pipe 32 close to the discharge position. Since the check rod 72 is close to the discharge position where the hanger roller 40 stops, a slight shaking of the hanger body will drive the hanger roller 40 to swing and contact the check rod 72. On the one hand, the frequent collision of the hanger roller 40 with the check rod 72 will affect the service life of the check rod 72. On the other hand, the swing amplitude of the hanger roller 40 is large, and the impact force on the check rod 72 is strong, which will also affect the service life of the check rod 72.

[0053] In the present application, since the check rod 72 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 check rod 72 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 check rod 72. On the other hand, when the hanger roller 40 swings to contact the check rod 72, most of its kinetic energy has been converted into gravitational potential energy, that is, at this time, the impact force with the check rod 72 is relatively small, which can also increase the service life of the check rod 72.

[0054] Please combine Figure 1 as well as Figure 3 As shown, in some embodiments, in the initial state, the anti-overshoot rod 71 spans the lifting track 50 along the X-axis direction, and at least part of the anti-overshoot rod 71 corresponds to the discharge pipe 32 along the Y-axis direction to avoid the hanger roller 40 from overshooting through the gap between the anti-overshoot rod 71 and the discharge pipe 32, thereby improving the anti-overshoot safety.

[0055] Specifically, the anti-overshoot rod 71 can be a straight rod, a curved rod or other shapes, as long as it can play a guiding and assisting effect. The present application does not give examples one by one here.

[0056] Please combine Figure 3 , Figure 4 as well as Figure 5 As shown, in some embodiments, a first limiting protrusion 711 and a second limiting protrusion 712 are fixed on the anti-overshoot rod 71;

[0057] In the initial state, the first limiting protrusion 711 abuts against the limiting pin 11 to limit the rotation of the guiding and assisting member 70 in the negative Z-axis direction, so as to prevent the situation that the guiding and assisting 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;

[0058] In the guiding state, the second limiting protrusion 712 abuts against the limiting pin 11 to limit the rotation of the guiding and assisting member 70 in the positive Z-axis direction.

[0059] Please refer to Figure 1 and Figure 2 As shown, in some embodiments, a guiding and assisting member 70 is hinged on each side of the housing 10 in the Y-axis direction; to increase the contact stability between the guiding and assisting member 70 and the hanger roller 40 and avoid the situation that the hanger roller 40 deflects in the Y-axis direction.

[0060] Please refer to Figure 1 and Figure 2 As shown, 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 both guiding and assisting members 70 are fixed to the rotating shaft 90, so that the two guiding and assisting members 70 can rotate synchronously, further improving the contact stability between the guiding and assisting member 70 and the hanger roller 40 and avoiding the situation that the hanger roller 40 deflects due to uneven contact.

[0061] In some embodiments, the elastic resetting 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] The second aspect of the present application provides a hanging lifting arm, including the above-mentioned discharging guiding and assisting structure.

[0063] The technical features of the above-mentioned embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above-mentioned 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.

[0064] The above-mentioned embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it cannot be understood 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 invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
