Description

Technical Field

[0001] The utility model relates to the technical field of garment production lines, in particular to an anti-overrun 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 hangers that have completed work at the work station or the bridging station and convey them back to the main track of the production line, so that the sewing materials on the hangers can enter the next process for processing;

[0003] Generally, the lifting push block in the lifting arm rotates cyclically under the drive of the motor to lift the hanger roller that enters the bottom of the lifting arm through the lifting arm entrance to the lifting arm exit at the top;

[0004] However, when the motor of the lifting arm is powered off and stops, the lifting push block may continue to slide down to the lifting arm entrance position under the action of inertia or its own gravity. When the subsequent hanger roller slides to the lifting arm entrance position, it will be blocked by the lifting push block and cannot enter the bottom of the lifting arm, resulting in problems such as the lifting push block lifting empty or a single lifting push block lifting double hangers after the lifting arm motor is restarted. Summary of the Utility Model

[0005] Based on this, in view of the problem that the lifting push block may overrun to the lifting arm entrance position after the lifting arm motor is turned off, resulting in subsequent problems such as empty lifting and double hangers, it is necessary to provide an anti-overrun structure and a hanging lifting arm in which the lifting push block will not overrun after the lifting arm motor is turned off and will not affect the subsequent operation of the lifting arm.

[0006] The present application first provides an anti-overrun structure, including a housing, a lifting assembly, and a lifting push block. The lifting assembly is disposed in the housing and is used to drive the lifting push block to move along a lifting track.

[0007] The anti-overrun structure further includes a braking member fixedly disposed on the housing. The braking member includes a braking portion located on the lifting track. When the lifting push block passes through the braking portion, the braking portion contacts and presses the lifting push block.

[0008] In one embodiment, the braking member extends along the Z-axis direction, and the braking member is located on one side of the lifting push block along the Y-axis direction.

[0009] In one embodiment, the anti-overrun structure further includes an adjusting member disposed on the housing. The adjusting member is located on the side of the braking member away from the lifting push block along the Y-axis direction;

[0010] The braking member can contact the adjusting member, and the contact position between the two is located between the fixed point and the braking portion of the braking member. The adjusting member can adjust the contact position with the braking member.

[0011] In one embodiment, the adjusting member is threadedly connected to the housing by a screw.

[0012] In one embodiment, the adjusting member is provided with an adjusting hole therethrough. The anti-overrun structure further includes an adjusting screw, which is threadedly connected to the adjusting hole, and the adjusting screw can contact the braking member.

[0013] In one embodiment, the adjusting member is provided with a plurality of the adjusting holes therethrough, and the adjusting holes are arranged at intervals along the length direction of the adjusting member.

[0014] In one embodiment, the adjusting member and the braking member are both fixed on the outer surface of the housing. The housing is provided with a through groove along the Y-axis direction, and at least a part of the braking portion penetrates through the through groove into the interior of the housing.

[0015] In one embodiment, the braking portion is V-shaped, and the top of the V-shape is used to contact the lifting push block.

[0016] In one embodiment, the anti-overrun structure further includes a Hall sensor. The Hall sensor is located on the front side of the braking member along the lifting track. A magnet is fixed on the lifting push block. The Hall sensor is used to detect the magnet, and the Hall sensor is electrically connected to the motor of the lifting assembly.

[0017] The second aspect of the present application provides a hanging lifting arm, including the above anti-overrun structure.

[0018] In the above anti-overrun structure, by providing a braking member, when the lifting push block slides down to the position of the braking member under the influence of inertia or its own gravity, since the braking portion is located on the lifting track, the lifting push block will contact and squeeze the braking portion, and the braking portion will undergo elastic deformation to clamp the lifting push block, that is, the braking member applies a frictional force to the lifting push block through the braking portion to realize the braking of the lifting push block, thereby preventing the lifting push block from sliding to the entrance position of the lifting arm and effectively preventing situations such as empty lifting and double clothes hangers.

[0030] For the convenience of description, in the present application, the lifting direction of the lifting assembly 20 is defined as the Z-axis direction, the direction perpendicular to the Z-axis direction in the plane where the lifting track is located is defined as the X-axis direction, and the direction perpendicular to both the X-axis direction and the Z-axis direction is defined as the Y-axis direction.

[0031] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown, the present application first provides an anti-overrun structure, including a housing 10, a lifting assembly 20 and a lifting push block 30. The lifting assembly 20 is disposed in the housing 10 and is used to drive the lifting push block 30 to move along the lifting track. The anti-overrun structure further includes a braking member 40. The braking member 40 is fixedly disposed in the housing 10. The braking member 40 includes a braking portion 41 located on the lifting track. When the lifting push block 30 passes through the braking portion 41, the braking portion 41 contacts and presses the lifting push block 30.

[0032] In the present application, by setting a brake member 40, when the lifting push block 30 slides down to the position of the brake member 40 due to inertia or its own gravity, since the brake part 41 is located on the lifting track, the lifting push block 30 will contact and squeeze the brake part 41, and the brake part 41 will undergo elastic deformation to clamp the lifting push block 30, that is, the brake member 40 applies friction force to the lifting push block 30 through the brake part 41 to achieve braking of the lifting push block 30, thereby preventing the lifting push block 30 from sliding to the entrance position of the lifting arm, effectively preventing the occurrence of empty lifting, double hangers, etc.

[0033] Specifically, the lifting assembly 20 includes a motor, two pulleys and a lifting belt. The two pulleys are rotatably connected to the shell 10. The lifting belt is transmission-connected between the two pulleys. The motor is used to drive one of the pulleys to rotate. The lifting push block 30 is fixed to the outer surface of the lifting belt.

[0034] Please combine Figure 1 , Figure 2 as well as Figure 3 As shown, in some embodiments, the brake member 40 extends along the Z-axis direction, and the brake member 40 is located on one side of the lifting push block 30 along the Y-axis direction.

[0035] When the brake part 41 clamps the lifting push block 30, the other side of the lifting push block 30 abuts against the inner wall of the shell 10, so the lifting push block 30 will not deviate to the other side. The brake part 41 can effectively clamp and brake the lifting push block 30 by relying on its own elastic restoring force.

[0036] Of course, in some other embodiments, the brake member 40 is also disposed on other sides of the lifting push block 30 , such as located on the lower side of the lifting push block 30 along the Z-axis direction, etc., which are not discussed in detail in the present application.

[0037] Please combine Figure 2 , Figure 3 as well as Figure 4 As shown, in some embodiments, the anti-overshoot structure also includes an adjusting member 50 arranged on the shell 10, and the adjusting member 50 is located on the side of the brake member 40 away from the lifting push block 30 along the Y-axis direction; the brake member 40 can contact the adjusting member 50, and the contact position of the two is located between the fixed point of the brake member 40 and the brake part 41, and the adjusting member 50 can adjust the contact position with the brake member 40.

[0038] Since the contact position between the adjusting member 50 and the braking member 40 is located between the fixed point of the braking member 40 and the braking portion 41, when the lifting push block 30 slides down to contact the braking portion 41, under the extrusion of the lifting push block 30, the braking member 40 will deform with the contact position between the adjusting member 50 and the braking member 40 as the fulcrum. By adjusting this contact position, the fulcrum position when the braking member 40 deforms can be adjusted, that is, the lever arm of the extrusion force of the lifting push block 30 on it is changed, and thus the force required for the braking member 40 to deform to the same extent is changed;

[0039] It is not difficult to understand that the greater the force required for the braking member 40 to deform to the same extent, the better the braking effect of the braking member 40 on the lifting push block 30. On the contrary, the braking effect is worse. Therefore, the anti-overrun structure of the present application can change the braking effect by adjusting the contact position between the adjusting member 50 and the braking member 40 to adapt to different actual needs, and has strong versatility.

[0040] Specifically, the adjusting member 50 can change the contact position with the braking member 40 by changing its own positional relationship with the housing 10. At this time, the adjusting member 50 is adjustably arranged on the housing 10. For example, the adjusting member 50 can rotate, translate, etc. relative to the housing 10; or the adjusting member 50 itself can be adjustable. For example, the adjusting member 50 itself can deform, or different shapes and sizes of adjusting members 50 can be selected and installed according to needs, etc.

[0041] Please refer to Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, the adjusting member 50 is threadedly connected to the housing 10 by a screw. After loosening the screw, the adjusting member 50 can rotate around the screw as the center, so as to change the contact position with the braking member 40. After the adjustment is completed, tightening the screw again can complete the fixation.

[0042] Of course, in some other embodiments, other common fixing methods can also be used between the adjusting member 50 and the housing 10. For example, there are multiple clamping positions on the housing 10, and the adjusting member 50 can be clamped to any clamping position, etc. As long as the adjusting member 50 is adjustably arranged on the housing 10 and can adjust the contact position between the adjusting member 50 and the braking member 40 according to needs.

[0043] Please refer to Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, the adjusting member 50 is provided with an adjusting hole 51 through it. The anti-overrun structure further includes an adjusting screw 60. The adjusting screw 60 is threadedly connected to the adjusting hole 51, and the adjusting screw 60 can contact the braking member 40.

[0044] The adjusting screw 60 can extrude the braking member 40 in the Y-axis direction, so that the initial position of the braking portion 41 in the Y-axis direction is changed, thereby realizing fine adjustment of the braking performance of the braking member 40.

[0045] Please refer to Figure 2 and Figure 3 As shown, in some embodiments, the adjusting member 50 is provided with a plurality of adjusting holes 51 penetrating therethrough, and the adjusting holes 51 are arranged at intervals along the length direction of the adjusting member 50; with such a setting, after the adjusting member 50 is rotated and adjusted relative to the housing 10, there is always an adjusting hole 51 corresponding to the braking member 40. Only by installing the adjusting screw 60 into the corresponding adjusting hole 51 can the fine adjustment of the braking performance of the braking member 40 be realized.

[0046] Please refer to Figure 2 , in some embodiments, both the adjusting member 50 and the braking member 40 are fixed on the outer surface of the housing 10. The housing 10 is provided with a through groove 11 in the Y-axis direction, and at least a part of the braking portion 41 penetrates through the through groove 11 into the interior of the housing 10.

[0047] Please refer to Figure 3 and Figure 4 As shown, in some embodiments, the braking portion 41 is V-shaped, and the top of the V-shape is used to contact the lifting push block 30.

[0048] The outer inclined surface of the V-shape can play a certain guiding role, preventing the lifting push block 30 from being stuck with the braking portion 41 while ensuring the provision of frictional force.

[0049] Please refer to Figure 3 As shown, in some embodiments, the anti-overrun structure further includes a Hall sensor 70. The Hall sensor 70 is located on the front side of the braking member 40 along the lifting track. A magnet is fixed on the lifting push block 30. The Hall sensor 70 is used to detect the magnet, and the Hall sensor 70 is electrically connected to the motor of the lifting assembly 20.

[0050] When the lifting push block 30 moves to the position where the Hall sensor 70 is located under the drive of the lifting assembly 20, the Hall sensor 70 detects the magnet on the lifting push block 30, triggers a signal to control the motor of the lifting assembly 20 to power off, and at the same time the braking portion 41 contacts the lifting push block 30 and applies a frictional force to it to complete the braking of the lifting push block 30 and prevent the lifting push block 30 from further slipping under the action of inertia.

[0051] Of course, in some other embodiments, the Hall sensor 70 can also be other sensors, as long as it can detect the lifting push block 30, and the present application does not make further limitations here.

[0052] The second aspect of the present application provides a hanging lifting arm, including the above anti-overrun structure.

[0053] 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 as the scope described in this specification.

[0054] The above-described embodiments only express several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but 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 present utility model patent shall be subject to the appended claims.
