Description

Technical Field

[0001] This invention relates to the field of garment production line equipment technology, specifically to an outgoing control device for a garment hanging line system. Background Technology

[0002] With the popularization of industrial automation, automated equipment for the garment industry has been widely used, especially in garment hanging line production lines. (See appendix) Figure 1 and attached Figure 2 The garment hanging line system uses a track 1 and hanger assemblies 2 mounted on the track 1. Each hanger assembly 2 includes rollers 201 and a hanger body 202 connected to the rollers 201. The track 1 transports the hanger assembly 2 to various workstations via the movement of the rollers 201. Each workstation is equipped with an exit control device to prevent the hanger assembly 2 from moving and to allow it to exit, thus controlling its departure.

[0003] Currently, the outbound control devices for garment hanging line systems on the market mainly utilize pneumatics as the primary actuator to achieve blocking and releasing functions. See the attached diagram for their structure. Figure 2 As shown, the departure control device mainly includes a cylinder 3, a lowering frame 5, and a claw 6. The lowering frame 5 is fixedly mounted on the track 1. The cylinder 3 is hinged to the lowering frame 5, and the claw 6 is hinged to the lowering frame 5 and also hinged to the piston rod 301 of the cylinder 3. The cylinder 3 is bidirectional and has two ports. By controlling the air intake of the two ports, compressed gas is used to drive the extension and retraction of its piston rod 301. When the solenoid valve switches the air path direction to change the air intake and exhaust of the two ports, the piston rod 301 of the cylinder 3 will extend or retract. When a user requests passage or a sensor detects feedback, the piston rod 301 of cylinder 3 retracts backward when the solenoid valve is ventilated, driving the chuck 6 to rotate counterclockwise. The front blocking part 601 on the front side of the chuck 6 no longer blocks the roller 201 of the first hanger assembly 2. Then, the roller 201 of the first hanger assembly 2 slides down freely under gravity or compression. At the same time, the rear side of the chuck 6 blocks the roller 201 of the second hanger assembly 2 from continuing to slide down. Then, the solenoid valve switches the air path direction, causing the piston rod 301 of cylinder 3 to push forward. The chuck 6 rotates clockwise back to its initial position. The front side continues to block the roller 201 of the second hanger assembly 2 and maintains this position, while the rear side disengages from the blocking roller 201. The above operation is repeated to achieve the cycle of blocking and releasing. In the initial state, when the air pressure in the garment factory is low or the production line is shut off after get off work, the piston rod 301 of cylinder 3 is in the extended state (i.e., the maximum stroke of cylinder 3). If no continuous and reasonable pressure is provided, the roller 201 of the hanger assembly 2 will cause the claw 6 to rotate counterclockwise under gravity or compression, causing the piston rod 301 of cylinder 3 to retract under force. Then the first hanger assembly 2 will automatically slide down and roll off under force, affecting the reasonable use of the production line. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the technical problem to be solved by the present invention is to provide an exit control device for a garment hanging line system, which can reliably prevent the movement of the hanger assembly and avoid the problem of the hanger assembly being released due to insufficient driving fluid in the power cylinder.

[0005] To achieve the above objectives, the present invention provides a departure control device for a garment hanging line system, used to control the departure of hanger assemblies on a track. The device includes a power cylinder, a lowering frame, and a clamp. The power cylinder is hinged to the lowering frame and can be either a pneumatic or hydraulic cylinder. The departure control device has an entry side for the hanger assembly and a departure side for the hanger assembly exiting. The clamp is hinged to the lowering frame and has a front blocking part and a rear blocking part, with the front blocking part located on the side of the rear blocking part closer to the departure side. The piston rod of the power cylinder can drive the clamp to rotate to either the front blocking position or the rear blocking position. When the clamp is in the front blocking position, the front blocking part can prevent the hanger assembly from moving towards the departure side on the track, while the rear blocking part cannot prevent the hanger assembly from moving. When the clamp is in the rear blocking position, the rear blocking part can prevent the hanger assembly from moving towards the departure side on the track, while the front blocking part cannot prevent the hanger assembly from moving. The departure control device also includes a connector. The system comprises a mechanism, a one-way valve, and a drive control mechanism. The power cylinder has an A port and a B port for the entry of power fluid, and a return spring for driving its piston rod. When power fluid enters the power cylinder through the A port, the power fluid drives the piston rod to move in a first direction, and the spring force of the return spring drives the piston rod to move in a second direction. The connector mechanism includes a C port, a D port, and an on / off control component. The on / off control component can control the connection or disconnection of the C port and the D port. The D port is connected to the B port of the power cylinder. The one-way valve is connected to the connector mechanism, with one end connected to the D port and the other end connected to the external fluid environment. The one-way valve is normally closed and opens when the pressure at the D port is lower than that of the external fluid environment. The A port of the power cylinder is connected to the drive control mechanism. The drive control mechanism is used to provide power fluid to the A port of the power cylinder and to control the operation of the on / off control component.

[0006] Furthermore, the power cylinder is a pneumatic cylinder.

[0007] Furthermore, the first direction of movement of the piston rod of the power cylinder is the retraction direction, and the second direction of movement is the extension direction. When the piston rod of the power cylinder extends to the maximum stroke position, it drives the drive pawl to rotate to the front blocking position.

[0008] Furthermore, the on / off control component of the connector mechanism includes a plunger, a disconnect holding spring, and a control interface. The drive control mechanism is connected to the control interface and can control the flow of power fluid into the control interface. The plunger can move to a blocked position and an open position. When no power fluid enters the control interface, the disconnect holding spring can drive the plunger to the blocked position and disconnect the C and D interfaces. When power fluid enters the control interface, it can drive the plunger to the open position and connect the C and D interfaces.

[0009] Furthermore, the connector mechanism is provided with an internal channel connecting the C interface and the D interface, and the plunger is provided with a connecting hole. When the plunger moves to the blocking position, the connecting hole is outside the internal channel and the plunger blocks the internal channel. When the plunger moves to the open position, the connecting hole is inside the internal channel.

[0010] Furthermore, the drive control mechanism includes a solenoid valve, a tee connector, and a pipeline. The inlet of the solenoid valve is used to connect to a power fluid source, and the outlet of the solenoid valve is connected to one interface of the tee connector through the pipeline. The other two interfaces of the tee connector are respectively connected to the control interface of the connector mechanism and the A interface of the power cylinder through the pipeline.

[0011] Furthermore, the hanger assembly includes rollers mounted on a track. When the claw is in the front blocking position, the front blocking part enters the movement path of the roller and can block the roller; when the claw is in the rear blocking position, the rear blocking part enters the movement path of the roller and can block the roller.

[0012] Furthermore, the chuck is located on the upper side of the track, and both the front and rear blocking parts enter the movement path of the roller from above.

[0013] Furthermore, the claw is made of plastic.

[0014] As described above, the departure control device of the present invention has the following beneficial effects:

[0015] By setting the power cylinder to a one-way action and setting a joint mechanism, a one-way valve, and a drive control mechanism to control the extension and retraction of the power cylinder, the pressure in the rodless chamber of the power cylinder can remain unchanged when blocking the exit state, thereby achieving the effect of locking the power cylinder, preventing the clothes hanger assembly from sliding out of the station, and allowing the clothes hanger to be released smoothly without affecting efficiency. The operation is stable and reliable, and it can effectively avoid the impact of oil or air entering the power cylinder. It can be improved on the existing structure with low modification cost, solves the problems in the use of the existing device, and improves the overall competitiveness of the product.

[0058] See Figures 1 to 9This invention provides a departure control device for a garment hanging line system, used to control the departure of a hanger assembly 2 on a track 1. The departure control device includes a power cylinder, a lowering frame 5, and a claw 6. The lowering frame 5 is fixedly installed beside the track 1, and the power cylinder is hinged to the lowering frame 5. The power cylinder can be a pneumatic or hydraulic cylinder, driven by a kinetic fluid such as compressed gas or hydraulic oil. The side of the departure control device used for the hanger assembly 2 to enter is called the entry side, and the side used for the hanger assembly 2 to exit is called the departure side. In this application, for ease of explanation, the direction of hanger departure movement is considered forward, that is, the departure side of the departure control device is its front side, and the entry side is its rear side. The chuck 6 is hinged to the lowering frame 5. The chuck 6 is provided with a front blocking part 601 and a rear blocking part 602. The front blocking part 601 is located on the side of the rear blocking part 602 closer to the exit side (i.e., the rear side). The piston rod 301 of the power cylinder 3 can drive the chuck 6 to rotate to the front blocking position or the rear blocking position. When the chuck 6 is in the front blocking position, the front blocking part 601 can prevent the hanger assembly 2 from moving toward the exit side on the track 1 and the rear blocking part 602 cannot prevent the hanger assembly 2 from moving. When the chuck 6 is in the rear blocking position, the rear blocking part 602 can prevent the hanger assembly 2 from moving toward the exit side on the track 1 and the front blocking part 601 cannot prevent the hanger assembly 2 from moving.

[0059] In this invention, the outbound control device further includes a connector mechanism 9, a one-way valve 7, and a drive control mechanism 8; wherein the power cylinder is unidirectional, that is, the piston rod 301 of the power cylinder moves in only one direction driven by the power fluid, and moves in the other direction driven by a return spring. The power cylinder 3 has an A port and a B port for the power fluid to enter, and a return spring for driving its piston rod 301 to move. The internal chambers of the power cylinder 3 located on both sides of the piston are respectively referred to as the rod chamber and the rodless chamber. The piston rod 301 is located in the rod chamber, and the return spring is located in the rodless chamber. The A port and the B port are connected to the rod chamber and the rodless chamber, respectively. When the power fluid enters the power cylinder 3 through the A port, the power fluid drives the piston rod 301 to move in the first direction, and the elastic force of the return spring drives the piston rod 301 to move in the second direction. The specific structural principle of the power cylinder is existing and will not be described in detail. The connector mechanism 9 includes a C-port 901, a D-port 902, and an on / off control component. The on / off control component can control the connection or disconnection of the C-port 901 and the D-port 902. The D-port 902 is connected to the B-port of the power cylinder. A one-way valve 7 is connected to the connector mechanism 9, with one end connected to the D-port 902 and the other end connected to the external fluid environment. The one-way valve 7 is normally closed and opens when the pressure at the D-port is lower than that of the external fluid environment. The A-port of the power cylinder is connected to a drive control mechanism 8. The drive control mechanism 8 provides power fluid to the A-port of the power cylinder and controls the operation of the on / off control component. In this application, the external fluid environment connected to the one-way valve 7 refers to an environment containing sufficient power fluid and with a basically stable pressure. The specific environment depends on the type of power fluid. For example, if the power fluid is air, the external fluid environment can be a stable atmospheric environment; if the power fluid is hydraulic oil, the external fluid environment can be a stable oil tank.

[0060] The main working principle of the departure control device involved in this invention is as follows: the first direction of the piston rod 301 of the power cylinder can be either a retracting direction or an extending direction. Furthermore, the piston rod 301 of the power cylinder can drive the chuck to rotate towards the forward blocking position when moving in the first direction, and drive the chuck to move towards the rear blocking position when moving in the second direction, or vice versa, in which case the working principle is the same. Taking the first direction of the piston rod 301 of the power cylinder as the retracting direction, and at this time driving the chuck to rotate towards the forward blocking position as an example, its working process is as follows: (a) In the initial state, see... Figure 8The claw 6 is located in the front blocking position, the front blocking part 601 is located within the path of the hanger assembly 2, and can block the foremost hanger assembly 2 so that it cannot move forward. At the same time, the rear blocking part 602 leaves the path of the hanger assembly 2, without affecting the subsequent hanger assembly 2 to enter and approach the foremost hanger assembly 2. The exit control device is in the exit blocking state. (b) When exiting the station, the drive control mechanism 8 supplies power fluid to the A port of the power cylinder. Simultaneously, the on / off control component connects the C port 901 and the D port 902, allowing power fluid to enter the A port of the power cylinder. This power fluid drives the piston rod 301 to retract in the rod chamber, causing the chuck 6 to rotate counterclockwise. During the retraction process, the return spring is compressed, reducing the volume of the rodless chamber in the power cylinder. The pressure of the power fluid increases and exceeds the external fluid environment connected to the one-way valve 7. The one-way valve 7 is normally closed, and the power fluid in the rodless chamber of the power cylinder is discharged through the B port, D port 902, and C port 901, ensuring the piston rod 301 can retract smoothly. The power cylinder drives the chuck 6 to rotate to the rear blocking position. (See [link to relevant documentation]). Figure 9The front blocking part 601 moves towards the exit side (front side) and leaves the path of the hanger assembly 2, no longer blocking the hanger assembly 2. At the same time, the rear blocking part 602 enters the path of the hanger assembly 2 and is located between the two foremost hanger assemblies 2, preventing the rear hanger assembly 2 from sliding forward. At this time, the exit control device is in the exit release state. Then, the drive control mechanism 8 stops supplying power fluid to the A port of the power cylinder, and at the same time controls the on / off control component to disconnect the C port 901 and the D port 902. The return spring drives the piston rod 301 to extend and move, and drives the pawl 6 to rotate clockwise. During the extension of rod 301, the volume of the rodless chamber in the power cylinder increases and the pressure decreases. When the pressure is less than the opening pressure (the pressure of the external fluid environment), the one-way valve 7 opens under the pressure of the external fluid environment. The power fluid in the external fluid environment is replenished into the rodless chamber of the power cylinder through the one-way valve 7 and the B interface to balance the pressure on both sides of the piston and prevent negative pressure from forming in the rodless chamber. This ensures that the piston rod 301 can extend smoothly under the action of the return spring. The piston rod 301 drives the pawl 6 back to the front blocking position, the exit control device returns to the initial state, and the one-way valve 7 also returns to the normally closed state. When the chuck 6 returns to the front blocking position, since the C-port 901 and D-port 902 are disconnected and the one-way valve 7 is normally closed, the pressure in the rodless chamber of the power cylinder can remain basically constant. At this time, although the hanger assembly 2 applies a forward force F to the front blocking part 601 of the chuck 6, the pressure in the rodless chamber and the elasticity of the return spring will cause the piston rod 301 to provide resistance to the chuck 6, preventing the chuck 6 from rotating counterclockwise to the rear blocking position. Therefore, even if the pressure of the power fluid source (air source or hydraulic oil source) is insufficient, that is, the pressure of the oil or air supplied to the power cylinder is insufficient, the hanger assembly 2 will not push the front chuck 6 away, thus ensuring the stable and reliable blocking effect.

[0061] The present invention will be further described below with reference to specific embodiments:

[0062] See Figure 5 , Figure 6 and Figure 7 In this embodiment, as a preferred design, the power cylinder is cylinder 3, which drives the piston rod 301 by compressed air. At this time, the external fluid environment connected to the one-way valve 7 is the atmospheric environment, resulting in a simpler structure and easier operation. A rotary joint 303 is fixedly connected to the end of the piston rod 301. The rotary joint 303 is hinged to the chuck 6 via a pin 4 for easy connection. An air pipe connector 302 is connected to the A port of cylinder 3 for easy connection to an air pipe.

[0063] See Figure 5 , Figure 6 and Figure 7In this embodiment, as a preferred design, the first direction of movement of the piston rod 301 of the power cylinder is the retraction direction, and the second direction is the extension direction. When the piston rod 301 of the power cylinder extends to its maximum stroke, that is, in the fully extended state, the pawl 6 is in the front blocking position, which can better stabilize the pawl 6 in the front blocking position. When the piston rod 301 of the power cylinder retracts, the pawl 6 rotates counterclockwise, see [reference]. Figure 9 Preferably, when the piston rod 301 of the power cylinder retracts to its maximum stroke, that is, when it is fully retracted, the pawl 6 is in the rear blocking position, which can better stabilize the pawl 6 in 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 retracts, the pawl 6 rotates clockwise, the principle is the same, and will not be described in detail.

[0064] See Figure 5 , Figure 6 and Figure 7 In this embodiment, as a preferred design, the on / off control component of the connector mechanism 9 includes a plunger 905, a disconnect holding spring 906, and a control interface 904. The drive control mechanism 8 is connected to the control interface 904 and can control the flow of power fluid into the control interface 904. The plunger 905 can move to the blocked position and the open position. When the control interface 904 is not receiving power fluid, the disconnect holding spring 906 can drive the plunger 905 to move to the blocked position, and the plunger 905 disconnects the C interface 901 and the D interface 902. When the control interface 904 receives power fluid, it can drive the plunger 905 to move to the open position, and the C interface 901 and the D interface 902 are connected. Furthermore, the connector mechanism 9 is provided with an internal channel 903 connecting the C interface 901 and the D interface 902, and a plunger movement channel 907 is provided. The plunger movement channel 907 passes through the internal channel 903, and the plunger 905 is disposed in the plunger movement channel 907. One end of the plunger movement channel 907 is connected to the control interface 904, and the other end is a plug 908. A disconnect holding spring 906 is disposed between the plug 908 and the plunger 905. The plug 908 limits the disconnect holding spring 906 and provides axial sealing. The plunger 905 is provided with a connecting hole. When compressed gas (power fluid) does not enter the D interface 902, the disconnect holding spring 906 drives the plunger 905 to move to the blocked position. At this time, the connecting hole is outside the internal channel 903, and the plunger 905 blocks the internal channel 903, and the C interface 901 and the D interface 902 are disconnected. See [reference needed]. Figure 6 As shown in the diagram; when compressed gas enters D port 902, the compressed gas drives the plunger 905 to move to the open position, disconnecting the retaining spring 906, which is then compressed. At this time, the connecting hole is located in the internal channel 903, which remains unobstructed through the connecting hole of the plunger 905. C port 901 and D port 902 remain connected. See [reference needed]. Figure 7The connector mechanism 9 is shown in the diagram. It has a one-way valve connection hole 909 that connects to an internal channel 903 for installing a one-way valve 7. The one-way valve 7 is connected to the D interface 902 through the internal channel 903. With this design, when a clothes hanger needs to be released, compressed gas can be supplied simultaneously to the control interface 904 of the connector mechanism 9 and the A interface of the cylinder via the drive control mechanism 8, making operation more convenient.

[0065] See Figure 5 , Figure 6 and Figure 7 In this embodiment, as a preferred design, the drive control mechanism 8 includes a solenoid valve 801, a three-way connector 802, and a pipeline 803. The inlet of the solenoid valve 801 is connected to a gas source (power fluid source), and the outlet of the solenoid valve 801 is connected to one port of the three-way connector 802 via the pipeline 803. The other two ports of the three-way connector 802 are respectively connected to the control port 904 of the connector mechanism 9 and the A port of the cylinder 3 via the pipeline 803. During the release operation, the solenoid valve 801 controls one of the outlets to supply compressed gas to the three-way connector 802. The three-way connector 802 simultaneously supplies gas to the A port of the cylinder 3 and the control port 904 of the connector mechanism 9. The C port 901 and the D port 902 are connected, and the cylinder 3 retracts. When resuming the blocking operation, the gas supply is stopped by the solenoid valve 801.

[0066] In other embodiments, the on / off control component may also adopt other suitable structures. Its operation may be controlled by gas or hydraulic oil, or by electrical signals or mechanical control. It can be used to promptly act when the piston rod 301 of the power cylinder moves and control the connection or disconnection of the C interface 901 and the D interface 902.

[0067] In this embodiment, as a preferred design, the C-port 901 of the connector mechanism 9 is also connected to a gas source via a gas pipe, and an element is provided in the middle that only allows gas to pass through in one direction. In this way, when the gas in the rodless chamber of the cylinder 3 is discharged, it can return to the gas source for recycling. The C-port 901 can also be directly connected to the atmospheric environment, thereby discharging the gas into the atmospheric environment.

[0068] 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 hanger moves along the track 1 by the roller 201 rolling on the track 1. Alternatively, the hanger assembly 2 can also move by sliding a hook on the track 1. Preferably, see [reference needed]. Figure 5 , Figure 8 and Figure 9When the claw 6 is in the front blocking position, the front blocking part 601 enters the movement 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 in the rear blocking position, the rear blocking part 602 enters the movement path of the roller 201 of the hanger assembly 2, directly blocking the movement of the roller 201. In other embodiments, the front blocking part 601 and the rear blocking part 602 may also contact other suitable positions of the hanger assembly 2 to achieve blocking, as long as they can prevent the hanger assembly 2 from moving forward.

[0069] In this embodiment, see Figure 5 , Figure 8 and Figure 9 The chuck 6 is located on the upper side of the track 1, and its rotation axis is perpendicular to the track 1 at this location, preferably horizontal. When the chuck 6 rotates, the front blocking part 601 and the rear blocking part 602 both move downward into the movement path of the roller 201.

[0070] In this embodiment, see Figure 5 The lowering frame 5 is directly fixed to the lower side of the track 1. Alternatively, the lowering frame 5 can be fixed to a fixing mechanism around the track 1, maintaining its fixation to the track 1. A support base 501 and a bracket 502 are fixed to the lowering frame 5. The bracket 502 is located at the top of the lowering frame 5, and the cylinder 3 is hinged to the bracket 502. The support base 501 is fixed inside the lowering frame 5 with screws, and the chuck 6 is hinged to the support base 501 via a rotating pin, facilitating installation.

[0071] In this embodiment, preferably, the claw 6 is made of plastic, which meets the performance requirements and can reduce the production cost of the parts.

[0072] As can be seen from the above, the departure control device of the present invention has the following beneficial effects:

[0073] By setting the power cylinder to a one-way action and setting a connector mechanism 9, a one-way valve 7, and a drive control mechanism 8 to control the extension and retraction of the power cylinder, the pressure in the rodless chamber of the power cylinder can remain unchanged when blocking the exit state, thereby achieving the effect of locking the power cylinder, preventing the clothes hanger assembly 2 from sliding out of the station, and allowing the clothes hanger to be released smoothly without affecting efficiency. The operation is stable and reliable, and it can effectively avoid the impact of oil or gas entering the power cylinder. It can be improved on the existing structure with low modification cost, solves the problems in the use of the existing device, and improves the overall competitiveness of the product.

[0074] In summary, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0075] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can 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 those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
