Abstract
Description
Technical Field
[0001] This invention relates to the field of workwear conveyor technology, specifically to a workwear feeding mechanism for a workwear conveyor and its usage method. Background Technology
[0002] Workwear conveyor lines are used to hang work clothes on hangers and transport them into workwear dryers and folding machines. These lines typically have multiple manual feeding stations. Due to inconsistent feeding speeds, hangers moving along the conveyor line can become too clustered or too loose, hindering subsequent drying and folding processes. Furthermore, existing workwear conveyor lines have fixed hanging heights, which inconveniences operators of different heights, affecting hanging efficiency and garment feeding. Therefore, these problems urgently need to be addressed. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide a workwear feeding mechanism and its usage method for a workwear conveyor line, which realizes uniform and sequential feeding of workwear and avoids excessive clustering or loosening of the hangers moving on the conveyor line, thereby facilitating subsequent work.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The innovative feature of the workwear feeding mechanism for a workwear conveyor line of the present invention is that the workwear feeding mechanism includes a fixed base, track I, track II, track III, track IV, a chain, a drive assembly, a hook assembly, a tension adjustment assembly, and a height adjustment assembly; the fixed base is arranged vertically and horizontally, and track III is horizontally fixed at the upper edge of its front surface, and track IV is vertically fixed at the left edge of its front surface; track II and track I are arranged in a V-shape with left and right intervals, and the left end of track II is located directly below the lower end of track IV, corresponding to the position on the front surface of the fixed base. The vertical rotation connection is as follows: the right end of track I is positioned at the lower right of the right end of track III, and is vertically rotatably connected to the front surface of the fixed base; the chain passes through track I, track II, track III, and track IV in a ring shape, and rotates counterclockwise under the drive of the drive component, and several hook components matching the clothes hanger are evenly distributed on it; a height adjustment component is also provided on the upper surface of track I, and the height of the left end of track I is adjusted by the height adjustment component; a tension adjustment component is also provided between the right end of track I and the right end of track III, and the tension adjustment component ensures that the chain is always in a taut state;
[0005] The operation method of the workwear feeding mechanism includes the following steps:
[0006] Step 1: When working, first manually give the photoelectric sensor a signal, the motor will start and drive the chain to rotate counterclockwise; at this time, the extension end of the blocking cylinder will extend and limit the clothes hanger on the front track;
[0007] Step 2: When proximity switch I detects the hook assembly, the extension end of the blocking cylinder retracts, the hanger begins to slide down the front track, and at the same time the extension end of the blocking cylinder extends again to limit the next hanger on the front track.
[0008] Step 3: When proximity switch II detects the hook assembly, the motor stops working. At this time, one of the hook assemblies moves with the chain to the inlet and waits. Then, the previously released hanger falls into the inlet with the second guide rod and rests on the corresponding hook assembly.
[0009] Step 4: Then manually give the photoelectric sensor signal again, the motor will work again and drive the chain to continue to rotate counterclockwise. At this time, the hanger moves to the hanging position with the hook assembly. During this process, the proximity switch I detects the next hook assembly, and at the same time the extension end of the blocking cylinder retracts and releases the next hanger.
[0010] Step 5: When the hanger moves to the hanging position, proximity switch II detects the next hook assembly. At this time, the motor stops working, and the next hook assembly moves with the chain to the inlet to wait. At the same time, the extension end of the first cylinder extends and clamps the hanger to secure it. At this time, the hanging operation can be performed.
[0011] Step Six: After the hanging operation is completed, manually send a signal to the photoelectric sensor again. The motor will start working again and drive the chain to continue rotating counterclockwise. When it moves to the L-shaped plate, the hanger will be detached from the corresponding hook assembly by the unloading plate and then fall onto the first guide rod, which will then convey it to the subsequent process. Repeat the above steps to form a cycle to complete the feeding and conveying.
[0012] Step 7: When the height of the hanging position needs to be lowered, under the drive of the electric push rod, guide rail I slides to the left along track I. Then, with the cooperation of guide rail I, hinge and guide rail II, track I rotates counterclockwise around its right end and track II rotates clockwise around its left end, thereby lowering the height of the hanging position. At this time, under the action of the spring, the chain is kept taut through the cooperation of the adjusting plate and adjusting gear.

[0019] Preferably, a fixing plate is horizontally fixed on the front surface of the fixing base, directly below the right half of the track III and directly above the electric push rod. The fixing plate does not interfere with the transmission of the hook assembly along the chain, and its front surface extends horizontally forward beyond the coverage area of the track III.

The adjusting gear is located on the outer side between the main gear and the driven gear I, and meshes with the chain. The adjusting gear is coaxially sleeved and fixed on the horizontally longitudinally arranged rotating shaft IV, and the rear end of the rotating shaft IV is rotatably connected to the front surface of the adjusting plate at a corresponding position. A spring is also provided on the left side of the adjusting plate. The right end of the spring is fixedly connected to the upper surface of the adjusting plate near its left end position, and does not interfere with the rotation of the adjusting gear. The spring is spaced apart on the rear side of proximity switch I and proximity switch II, and its left end is fixedly connected to the lower surface of the fixed plate near its left end position. Thus, through the cooperation of the spring, the adjusting plate and the adjusting gear, the tension of the chain is adjusted to ensure that the chain is always in a taut state.
[0021] Preferably, it further includes a front rail, a blocking cylinder, a mounting bracket, a second guide rod, a sealing plate, a guide plate, and a rubber plate; the sealing plate is vertically and horizontally spaced in front of the driven gear II, and is screwed to the fixed seat. The sealing plate covers the left end of the driven gear II, the left end of the rail III, and the upper end of the rail IV, ensuring that it does not interfere with the transmission of the hook assembly along the chain; a first chamfer is also provided at the lower end of the sealing plate, and the first chamfer is inclined downward from front to back; the guide plates are vertically and horizontally spaced in front of the rail IV, and are spaced directly below the sealing plate; the guide plates are vertically and horizontally spaced in front of the rail IV, and are spaced directly below the sealing plate; the guide plates are vertically and horizontally spaced in front of the driven gear II, and are spaced directly below the sealing plate; the guide plates are vertically and horizontally spaced in front of the driven gear II, and are screwed to the fixed seat.

[0022] The front track is horizontally inclined longitudinally, and its rear end extends downwards at an angle to near the inlet, and is spaced apart from the sealing plate and guide plate respectively. A second guide rod is provided in an arc transition shape between the rear end face of the front track and the upper end of the guide plate. The upper end of the second guide rod is fixedly connected to the rear end face of the front track at a corresponding position, and its lower end is fixedly connected downwards to the upper end of the guide plate at a position relative to the apex of the second inclination angle. The second guide rod guides the hanger from the front track down into the inlet. A mounting bracket is also provided in the rear half of the front track, and is installed... The frame is fixedly connected to the upper part of the front surface of the sealing plate, and it must be ensured that the mounting frame does not interfere with the action of the hanger falling along the front track to the inlet. A blocking cylinder is also provided on the front track relative to the front side of the mounting frame. The blocking cylinder is electrically connected to the proximity switch I and does not interfere with the action of the hanger falling along the front track to the inlet. The blocking cylinder limits the action of the hanger falling along the front track.

A first cylinder is also horizontally and longitudinally positioned below track I. The tail of the first cylinder is fixedly connected to the rear inner side of the bracket, and its telescopic end is horizontally and longitudinally forward-facing, and fixedly connected to the rear surface of the vertically and transversely positioned clamping plate, thereby driving the clamping plate to move horizontally and longitudinally inside the bracket. When the hook assembly is conveyed to the position inside the bracket by the chain, the distance between the hook assembly and the front inner surface of the bracket must be less than the thickness of the hook end of the hanger. Thus, driven by the first cylinder, the clamping plate abuts the hanger against the front inner side of the bracket, ensuring the stability of the hanging action.
[0024] Preferably, the assembly further includes an L-shaped plate, a first guide rod, and a discharge plate. An L-shaped plate is mounted on the right end of track I, with its horizontal edge fixedly connected to the upper surface of track I. The vertical edge of the L-shaped plate is located at the front of track I and extends vertically downwards beyond the lower surface of track I, without interfering with the chain's transmission of the hook assembly. A discharge plate is horizontally and longitudinally mounted on the lower surface of track I relative to the L-shaped plate. A first guide rod is horizontally and longitudinally fixed on the inner surface of the vertical edge of the L-shaped plate near its end. The first guide rod is spaced apart directly below the discharge plate, with its rear end inclined downwards. The front end of the discharge plate extends horizontally and longitudinally forward and bends upwards, without interfering with the chain's transmission of the hook assembly. The discharge plate then limits the rightward movement of the hanger on the corresponding hook assembly, and with the rotation of the chain, the hanger is disengaged from the corresponding hook assembly, falling onto the first guide rod and then conveyed to the subsequent process via the first guide rod.

[0047] like Figures 1-6 As shown, the front track 18 is horizontally inclined longitudinally, and its rear end extends downwards at an angle to near the inlet, and is spaced apart from the sealing plate 36 and the guide plate 23 respectively; a second guide rod is provided in an arc transition shape between the rear end face of the front track 18 and the upper end of the guide plate 23. The upper end of the second guide rod is fixedly connected to the rear end face of the front track 18 at a corresponding position, and its lower end is fixedly connected downwards to the upper end of the guide plate 23 at a position relative to the top of the second inclination angle, thereby guiding the hanger 9 from the front track 18 down into the inlet through the second guide rod; a mounting bracket 20 is also provided in the rear half of the front track 18, and the mounting bracket 20 is connected to the sealing plate 36. The front surface is fixedly connected at a position slightly above, and it must be ensured that the mounting bracket 20 does not interfere with the action of the hanger 9 falling along the front rail 18 to the inlet. A blocking cylinder 19 is also provided on the front rail 18 relative to the front side of the mounting bracket 20. The blocking cylinder 19 is electrically connected to the proximity switch I 12 and does not interfere with the action of the hanger 9 falling along the front rail 18 to the inlet. The blocking cylinder 19 limits the action of the hanger 9 falling along the front rail 18. The distance between the proximity switch I 12 and the proximity switch II 13 must be such that when the hanger 9 is released and falls to the inlet, the motor 7 stops working and one of the hook components 32 stays at the inlet waiting.
[0048] The present invention also provides a photoelectric eye 8 on the lower surface of track II3, slightly to the left of its center. The photoelectric eye 8 is electrically connected to the motor 7 and does not interfere with the movement of the clothes hanger 9 along with the hook assembly 32. Figures 1-6As shown, an inverted U-shaped bracket 29 is also installed on the left end of track I2. The opening slot of the bracket 29 is set along the length of track I2 and does not interfere with the transmission of the hook assembly 32 with the chain 22 and the vertical rotation of track II3, and rotates vertically synchronously with track I2. The two opening ends of the bracket 29 extend vertically downward from the lower surface of track I2, and a first cylinder 30 is horizontally and longitudinally installed inside the bracket 29 at a position relative to the lower part of track I2. The tail of the first cylinder 30 is fixed to the rear inner side of the bracket 29. The connection is made with its telescopic end facing forward horizontally and fixedly connected to the rear surface of the vertically and horizontally arranged clamping plate 31, thereby driving the clamping plate 31 to move horizontally and longitudinally inside the bracket 29; when the hook assembly 32 is conveyed to the position inside the bracket 29 by the chain 22, the distance between the hook assembly 32 and the front inner surface of the bracket 29 must be less than the thickness of the hook end of the hanger 9, so that under the drive of the first cylinder 30, the clamping plate 31 abuts the hanger 9 against the front inner side of the bracket 29, ensuring the stability of the hanging action.
[0049] In this invention, an L-shaped plate 33 is also mounted on the right end of track I2, and the horizontal side of the L-shaped plate 33 is fixedly connected to the corresponding position on the upper surface of track I2, such as... Figures 1-6 As shown, the vertical edge of the L-shaped plate 33 is located on the front side of the track I2 and extends vertically and horizontally downward beyond the lower surface of the track I2, without interfering with the transmission of the hook assembly 32 along the chain 22. A discharge plate 35 is also horizontally and longitudinally arranged on the lower surface of the track I2 relative to the L-shaped plate 33, and a first guide rod 34 is horizontally and longitudinally fixed on the inner surface of the vertical edge of the L-shaped plate 33 near its end. The first guide rod 34 is spaced apart directly below the discharge plate 35, and its rear end is inclined downward. The front end of the discharge plate 35 extends horizontally and longitudinally forward and bends upward, without interfering with the transmission of the hook assembly 32 along the chain 22. The discharge plate 35 then limits the right position of the hanger 9 on the corresponding hook assembly 32, and with the rotation of the chain 22, the hanger 9 is disengaged from the corresponding hook assembly 32, so that the hanger 9 falls onto the first guide rod 34 and is then conveyed to the subsequent process via the first guide rod 34.
[0050] A method for using a workwear feeding mechanism in a workwear conveyor line according to the present invention, such as... Figures 1-6 As shown, it includes the following steps:
[0051] Step 1: When working, first manually give a signal to the photoelectric sensor 8, the motor 7 will work and drive the chain 22 to rotate counterclockwise; at this time, the extension end of the blocking cylinder 19 will extend and limit the clothes hanger 9 on the front track 18.
[0052] Step 2: When the proximity switch I12 detects the hook assembly 32, the telescopic end of the blocking cylinder 19 retracts, and the hanger 9 begins to slide down the front rail 18. At the same time, the telescopic end of the blocking cylinder 19 extends again and limits the next hanger 9 on the front rail 18.
[0053] Step 3: When proximity switch II 13 detects hook assembly 32, motor 7 stops working. At this time, one of the hook assemblies 32 moves with chain 22 to the inlet and waits. Then, the previously released hanger 9 falls into the inlet with the second guide rod and rests on the corresponding hook assembly 32.
[0054] Step 4: Then manually give the photoelectric sensor 8 a signal again, the motor 7 will work again and drive the chain 22 to continue to rotate counterclockwise. At this time, the hanger 9 moves to the hanging position with the hook assembly 32. During this process, the proximity switch I12 detects the next hook assembly 32, and at the same time, the telescopic end of the blocking cylinder 19 retracts and releases the next hanger 9.
[0055] Step 5: When the hanger 9 moves to the hanging position, the proximity switch II 13 detects the next hook assembly 32. At this time, the motor 7 stops working, and the next hook assembly 32 moves with the chain 22 to the inlet to wait. At the same time, the telescopic end of the first cylinder 30 extends and clamps the hanger 9 to fix it. At this time, the hanging operation can be performed.
[0056] Step Six: After the hanging operation is completed, manually send a signal to the photoelectric sensor 8 again, and the motor 7 will start working again and drive the chain 22 to continue to rotate counterclockwise. When it moves to the position of the L-shaped plate 33, the hanger 9 will be separated from the corresponding hook assembly 32 by the unloading plate 35, and then fall onto the first guide rod 34, and be conveyed to the subsequent process by the first guide rod 34; repeat the above steps to form a cycle to complete the feeding and conveying.
[0057] Step 7: When the height of the hanging position needs to be lowered, under the drive of the electric push rod, guide rail I25 slides to the left along track I2. Then, with the cooperation of guide rail I25, hinge 28 and guide rail II27, track I2 rotates counterclockwise around its right end and track II3 rotates clockwise around its left end, thereby lowering the height of the hanging position. At this time, under the action of spring 16, the chain 22 is kept taut through the cooperation of adjusting plate 17 and adjusting gear 21.
[0058] The beneficial effects of this invention are:
[0059] (1) The present invention realizes the uniform feeding of work clothes one by one, and avoids the situation of the clothes hangers 9 moving on the conveyor line being too clustered or loose, which is beneficial to subsequent work;
[0060] (2) The present invention facilitates the height adjustment of the hanging position by using electric push rod, track I2, track II3, guide rail I25, guide rail II27 and hinge 28, thus making it suitable for hanging clothes for operators of different heights and with a wide range of applications.
[0061] (3) The present invention uses the spring 16, the adjusting plate 17 and the adjusting gear 21 to facilitate the adjustment of the tension of the chain 22, so that the chain 22 is always in a taut state, ensuring the smooth transport of the work clothes.
