Description

Technical Field

[0001] The utility model relates to the technical field of clothing production line equipment, in particular to an exit control device of a clothing hanging line system. Background Art

[0002] With the popularization of industrial automation, clothing automation equipment has been widely used, especially in the production line of clothing hanging line system. Figure 1 and attached Figure 2 The clothing hanging line system is provided with a track 1 and a hanger assembly 2 installed on the track 1. The hanger assembly 2 includes a roller 201 and a hanger body 202 connected to the roller 201. The track 1 transports the hanger assembly 2 to each workstation through the movement of the roller 201 on the track 1. An exit control device is provided at the workstation to realize the function of blocking the movement of the hanger assembly 2 and releasing it, thereby controlling the exit of the hanger assembly 2.

[0003] At present, the exit control device of the clothing hanging line system on the market mainly uses gas as the main actuator to realize the functions of blocking and releasing. Its structure is shown in the attached Figure 2 As shown, the exit control device mainly includes structures such as a cylinder 3, a lower frame 5 and a claw 6. The lower frame 5 is fixedly arranged on the track 1, the cylinder 3 is hinged to the lower frame 5, the claw 6 is hinged to the lower frame 5, and is hinged to the piston rod 301 of the cylinder 3. When the user has a release demand or the sensor automatically senses the feedback, the piston rod 301 of the cylinder 3 retracts backward when the solenoid valve is ventilated to drive the claw 6 to rotate counterclockwise, and the front blocking part 601 on the front side of the claw 6 no longer blocks the roller 201 of the first hanger assembly 2 on the front side, and then the roller 201 of the first hanger assembly 2 slides freely under gravity or extrusion, and at the same time, the rear side of the claw 6 blocks the roller 201 of the subsequent second hanger assembly 2 from continuing to slide down, and then the solenoid valve switches the air path direction to make the piston rod 301 of the cylinder 3 push forward, and the claw 6 rotates clockwise to return to the initial position, and the front side continues to block the roller 201 of the subsequent hanger assembly 2 and maintains it, and the rear side disengages from the blocking roller 201, and the above operation is repeated to realize the blocking and releasing cycle. In the initial state, when the gas source pressure in the garment factory is low or the production line is cut off after get off work, the piston rod 301 of the cylinder 3 is in an extended state (i.e., the maximum stroke of the cylinder 3). If continuous and reasonable pressure is no longer provided, the roller 201 of the hanger assembly 2 will cause the claw 6 to rotate counterclockwise under gravity or extrusion, causing the piston rod 301 of the cylinder 3 to retract under force, and then the first hanger assembly 2 will automatically slide down and roll under the force, affecting the reasonable use of the production line.

[0045] It should be noted that the structures, proportions, sizes, etc. drawn in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0046] See also Figures 1 to 7 The utility model provides an exit control device for a clothing hanging line system, which is used to control the exit of a hanger assembly 2 on a track 1. The exit control device includes a power cylinder, a lower rack 5 and a claw 6. The lower rack 5 is fixedly arranged beside the track 1. The power cylinder is hinged to the lower rack 5. The power cylinder is a gas or hydraulic cylinder, which is driven by a driving fluid such as gas or hydraulic oil. The power cylinder is a bidirectional cylinder with two interfaces. The air or oil intake of the two interfaces is controlled to drive the telescopic movement of its piston rod 301. The power cylinder is an existing structure, and the specific structural principle will not be described in detail. The side of the exit control device for the hanger assembly 2 to enter is the entry side, and the side for the hanger assembly 2 to exit is the exit side. In this application, for the convenience of explanation, the direction of the hanger exit movement is the front, that is, the exit side of the exit control device is its front side, and the progress side is its rear side. The claw 6 is hinged to the lower rack 5, and is provided with a front blocking portion 601 and a rear blocking portion 602, and the front blocking portion 601 is located on the side of the rear blocking portion 602 close to the exit side (i.e., the rear side), and the claw 6 can be rotated to a front blocking position or a rear blocking position; when the claw 6 is located at the front blocking position, the front blocking portion 601 can block the hanger assembly 2 from moving toward the exit side on the track 1 and the rear blocking portion 602 cannot block the movement of the hanger assembly 2; when the claw 6 is located at the rear blocking position, the rear blocking portion 602 can block the hanger assembly 2 from moving toward the exit side on the track 1 and the front blocking portion 601 cannot block the movement of the hanger assembly 2. The exit control device also includes a self-locking transmission mechanism 7 connecting the piston rod 301 of the power cylinder and the claw 6. When the piston rod 301 of the power cylinder moves, it can drive the claw 6 to rotate through the self-locking transmission mechanism 7. When the claw 6 rotates to the front blocking position, the self-locking transmission mechanism 7 is in a locked posture and can lock the position of the claw 6 so that the claw 6 cannot rotate toward the rear blocking position. When the piston rod 301 of the power cylinder moves, the self-locking transmission mechanism 7 can release the locked posture.

[0047] The main working principle of the exit control device involved in the utility model is: (a) in the initial state, refer to Figure 6 , the claw 6 is located at the front blocking position, the front blocking portion 601 is located within the path of the hanger assembly 2, and can block the frontmost hanger assembly 2 from moving forward, and at the same time the rear blocking portion 602 leaves the path of the hanger assembly 2, does not affect the subsequent hanger assembly 2 from entering and approaching the frontmost hanger assembly 2, and the exit control device is in the exit blocking state; (b) when it is necessary to release the exit, the piston rod 301 of the power cylinder moves, see Figure 7 , the self-locking transmission mechanism 7 drives the claw 6 to rotate counterclockwise to the rear blocking position, so that the front blocking portion 601 moves toward the exit side (front side) and leaves the path of the hanger assembly 2, no longer blocking the hanger assembly 2, and at the same time, the rear blocking portion 602 enters the path of the hanger assembly 2 and is located between the two front hanger assemblies 2, blocking the rear hanger assembly 2 from sliding forward. At this time, the exit control device is in the exit release state; then the piston rod 301 of the power cylinder moves in the opposite direction, and the self-locking transmission mechanism 7 drives the claw 6 to rotate clockwise back to the front blocking position, see Figure 6 , the front blocking portion 601 of the claw 6 resumes blocking the hanger assembly 2 which is now at the front, and the exit control device returns to the initial state. At this time, the self-locking transmission mechanism 7 is in a locked position and can lock the position of the claw 6 so that the claw 6 cannot rotate toward the rear blocking position. At this time, even if the hanger assembly 2 applies a forward force F to the front blocking portion 601 of the claw 6, the claw 6 will not rotate. At this time, even if the oil or gas pressure of the power cylinder is insufficient, the hanger assembly 2 will not push the front claw 6 away, thereby ensuring a stable and reliable blocking effect. When the piston rod 301 of the power cylinder moves, the self-locking transmission mechanism 7 can be released from the locked position, which will not affect the normal rotation of the claw 6 driven by the piston rod 301.

[0048] The exit control device of the utility model can achieve a self-locking effect when blocking the exit state to prevent the hanger assembly 2 from sliding down and out of the station. It works stably and reliably, can effectively avoid the influence of oil or gas entering the power cylinder, and can be improved on the existing structure with low modification cost.

[0049] See also Figure 5 , Figure 6 and Figure 7In this embodiment, as a preferred design, the self-locking transmission mechanism 7 includes a fixed frame 703, a transmission link 701 and a locking assembly. The fixed frame 703 is fixedly mounted on the lower frame 5. One end of the transmission link 701 is hinged to the claw 6 through the hinge point B, and the other end is hinged to the piston rod 301 of the power cylinder through the hinge point C. The locking assembly is mounted on the fixed frame 703 and connected to the transmission link 701. When the claw 6 rotates to the front blocking position, the locking assembly applies a force F2 to the transmission link 701, and the force F2 is parallel to the line connecting the hinge point C and the hinge point B and points to the hinge point B. Further, the locking assembly includes a locking link 702, one end of the locking link 702 is hinged to the fixed frame 703 through the hinge point D, and the other end is hinged to the hinge point C of the transmission link 701 and the piston rod 301. When the claw 6 rotates to the front blocking position, the hinge point B, the hinge point C and the hinge point D are collinear. When the claw 6 rotates to the front blocking position, see Figure 6 At this time, the hanger assembly 2 will apply a forward force F to the front blocking portion 601 of the claw 6, and the force F will form a torque M to drive the claw 6 to move in the counterclockwise direction. The claw 6 will apply a force F1 along the line connecting the hinge point C and the hinge point B to the transmission link 701. At this time, since the hinge point B, the hinge point C and the hinge point D are collinear, the locking link 702 will apply a force F2 to the transmission link 701. The force F2 is along the line connecting the hinge point C and the hinge point B and points to the hinge point B. It is opposite to the force F1 and can prevent the transmission link 701 from moving, thereby preventing the claw 6 from rotating. The entire self-locking transmission mechanism 7 is in a locked posture, realizing the position locking of the claw 6, so that it cannot rotate toward the rear blocking position. When the piston rod 301 of the power cylinder moves, it can drive the hinge point C, so that the hinge points B, C and D are no longer collinear, and the locking state is released, and the locking link 702 and the transmission link 701 can rotate smoothly and normally.

[0050] See also Figure 5 , Figure 6 and Figure 7 In this embodiment, further, when the claw 6 rotates to the front blocking position, the hinge point C is located between the hinge point B and the hinge point D, that is, the locking link 702 and the transmission link 701 are in the same line and in opposite directions. Of course, the locking link 702 and the transmission link 701 can also be in the same line and in the same direction, that is, the hinge point B and the hinge point D are both located on the same side of the hinge point C.

[0051] See also Figure 5 , Figure 6 and Figure 7In this embodiment, as a preferred design, the power cylinder is an air cylinder 3, and two air pipe joints 302 are provided on the air cylinder 3 for connecting with an air source to inlet and outlet air. The telescopic movement of the piston rod 301 is controlled by controlling the inlet and outlet air of the two air pipe joints 302. The end of the piston rod 301 is fixedly connected with a rotating joint 303, and is hinged with the claw 6 through the rotating joint 303 for convenient connection. The locking link 702, the claw 6 and the transmission link 701 are hinged together through a long shaft pin 4, and the long shaft pin 4 passes through the rotating joint 303, the locking link 702 and the transmission link 701 at the same time, and the three are hinged at the same time to form a hinge point C. The long shaft pin 4 adopts a cotter pin for convenient connection.

[0052] In this embodiment, the locking assembly is not limited to the above-mentioned form of the locking link 702, and may also be other suitable structures, which can apply a force F2 parallel to the line connecting the hinge point C and the hinge point B and directed to the hinge point B to the transmission link 701. In addition, the self-locking transmission mechanism 7 is also not limited to the above-mentioned form, and may also be other suitable mechanisms, which can achieve the above-mentioned transmission and locking functions.

[0053] In this embodiment, see Figure 6 When the piston rod 301 of the power cylinder extends, the claw 6 rotates clockwise, and preferably when the piston rod 301 of the power cylinder extends to the maximum stroke, that is, when it is fully extended, the claw 6 is located at the front blocking position, which can better keep the claw 6 stably at the front blocking position. When the piston rod 301 of the power cylinder retracts, the claw 6 rotates counterclockwise, see Figure 7 Preferably, when the piston rod 301 of the power cylinder is retracted to the maximum stroke, that is, when it is fully retracted, the claw 6 is located at the rear blocking position, which can better keep the claw 6 stably at the front blocking position. Of course, in other embodiments, it can also be the other way around, that is, when the piston rod 301 of the power cylinder is retracted, the claw 6 rotates clockwise, the principle is the same, and no further description is given.

[0054] In this embodiment, the hanger assembly 2 includes a roller 201 mounted on the track 1, and a hanger body 202 connected to the roller 201. The roller 201 rolls on the track 1 and moves along the track 1. Of course, the hanger assembly 2 can also move by sliding the hook on the track 1. Preferably, when the claw 6 is located at the front blocking position, the front blocking portion 601 enters the moving path of the roller 201, directly blocking the movement of the roller 201, thereby better blocking the movement of the hanger assembly 2. Similarly, when the claw 6 is located at the rear blocking position, the rear blocking portion 602 enters the moving path of the roller 201 of the hanger assembly 2, directly blocking the movement of the roller 201. Obviously, in other embodiments, the front blocking portion 601 and the rear blocking portion 602 can also be in contact with other suitable positions of the hanger assembly 2 and achieve blocking, so as to block the hanger assembly 2 from moving forward.

[0055] In this embodiment, see Figure 5 , Figure 6 and Figure 7 The claw 6 is located on the upper side of the track 1, and its rotation axis is perpendicular to the track 1 here, and is preferably horizontal. When the claw 6 rotates, the front blocking portion 601 and the rear blocking portion 602 both move downward into the moving path of the roller 201.

[0056] In this embodiment, see Figure 5 , Figure 6 and Figure 7 The lower rack 5 is directly fixedly connected to the lower side of the track 1. Of course, the lower rack 5 can also be fixed to the fixing mechanism around the track 1 to keep it fixed to the track 1. The lower rack 5 is fixed with a support seat 501 and a bracket 502. The bracket 502 is located at the top of the lower rack 5, and the cylinder 3 is hinged on the bracket 502. The support seat 501 is fixed to the inside of the lower rack 5 by screws, and the claw 6 is hinged to the support seat 501 by a rotating pin, which is convenient for installation.

[0057] In this embodiment, preferably, the claw 6, the support seat 501, the locking link 702, and the transmission link 701 are all made of plastic, which meets the performance requirements and can reduce the production cost of parts.

[0058] As can be seen from the above, the exit control device of the utility model has the following beneficial effects:

[0059] By optimizing the transmission structure, a locking effect can be achieved when blocking the exit state, preventing the hanger assembly 2 from sliding down and exiting the station, while allowing the hanger to be released smoothly without affecting efficiency. The operation is stable and reliable, and the influence of oil or gas entering the power cylinder can be effectively avoided. The same cylinder 3 can also be used as the main actuator to improve the existing structure with low modification costs, thus solving the problems encountered in the use of the existing device and improving the overall competitiveness of the product.

[0060] In summary, the utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0061] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
