Description

Technical Field

[0001] The present invention relates to the technical field of feeders, and in particular to a hose feeder and a control method thereof. Background Art

[0002] During radiator production, coolant lines must be installed. EPDM rubber hoses are widely used in radiators of construction vehicles due to their high-temperature and pressure resistance, excellent thermal insulation, and flexibility. Before installing the hoses on the radiator, they must be cut to the appropriate length to meet the specific radiator assembly requirements.

[0003] Chinese utility model patent publication number CN215701978U discloses an anti-drift hose cutting machine, comprising a base, a U-shaped plate, a material guide trough, and a control box. A support frame is fixed to the upper side of the base, and a feed assembly is fixed to the support frame. A second support plate is fixed to the inner wall of the base, and an electric telescopic rod is fixed to the second support plate, one end of which is fixed to the support assembly. A conveyor belt is fixed to the base, and a third hydraulic cylinder is fixed to the U-shaped plate. An auxiliary fixing assembly is fixed to the U-shaped plate. The anti-drift hose cutting machine is provided with a support assembly and an auxiliary fixing assembly. The second hydraulic cylinder assists in adjusting the position of the curved plate, allowing the four sets of curved plates to adjust their inner diameters. Finally, the machine can limit the position of hoses with different inner diameters. The fourth hydraulic cylinder assists in driving the auxiliary fixing plate to move, thereby limiting the position of the hose and preventing it from moving during cutting.

[0004] Typically, hose materials are stored and transported in bundles. The traditional method of loading hoses involves loosening the bundle, placing the hose on the ground or allowing it to rotate freely on a rotating table, and then pulling one end of the hose onto a cutting machine for cutting. Placing the bundled hose on the ground creates significant friction between the ground and the bundled hose, creating significant resistance when the cutting machine's feed rollers drive the hoses. This can cause the hoses to slip, preventing them from accurately delivering the desired length, impacting processing accuracy. Placing the bundled hoses on a rotating table allows them to rotate, overcoming the problem of slippage between the feed rollers and the cutting machine's feed rollers due to the high resistance to movement. However, after the cutting machine's feed rollers stop moving, the rotating table continues to rotate due to its own inertia, causing excessive hose to be delivered, which can easily become entangled in surrounding objects and cause inconvenience. Therefore, the prior art lacks a hose feeder that automatically adjusts the feed speed based on the speed at which the hose material is pulled through the cutting station. Summary of the Invention

The rotary driving member 52 drives the lower roller shaft 35 to rotate through the driving pulley 53 , the driving belt 54 and the driven pulley 55 , thereby realizing the function of driving the lower roller shaft 35 to rotate.

[0041] refer to Figure 1 、 Figures 4 to 7The rotating platform includes a base 61, a fixed sleeve 62, a lifting sleeve 63, a connecting frame 65, an annular guide rail 71, a slider 72, an abutment plate 73, and a material support plate 74.

The slider 72 is slidably connected to the annular guide rail 71, the abutment plate 73 is fixedly mounted on the slider 72, and the lower side of the material support plate 74 abuts the upper side of the abutment plate 73. The connecting frame 65 is fixedly connected to an annular baffle 66, which surrounds the material support plate 74.

The lifting sleeve 63 is slidably connected to the connecting frame 65. The base 61 is fixedly mounted with a lifting drive 64, which is connected to the lifting sleeve 63. The lifting drive 64 is a hydraulic cylinder. The base 61 is fixedly connected to a support column 68, which engages with the underside of a material support plate 74.

The external reinforcing rib 76 is fixedly connected to the support rib 75. An inclined nozzle 78 is fixedly mounted on the connecting frame 65, tilted and facing the support rib 75. The connecting frame 65 is rotatably connected to a plurality of second guide rollers 69 located at the opening 67. The second guide rollers 69 contact the hose material 81 at the opening 67, reducing friction when the hose material 81 passes through the opening 67 and preventing scratches on the surface of the hose material 81.

[0042] A control method for a hose feeder comprises the following steps:

[0043] S1. Place the hose material 81 on the rotating platform, pass one end of the hose material 81 through the guide roller mechanism and the movable space 16 in sequence, and then connect it to the cutting station;

[0044] S2. The tightness detection component detects the tightness of the hose material 81. If the upper sensing unit and the lower sensing unit do not detect the hose material 81, the process proceeds to step S3. If the upper sensing unit detects the hose material 81, the process proceeds to step S4. If the lower sensing unit detects the hose material 81, the process proceeds to step S5.

[0045] S3, the control module controls the driving mechanism to operate at a slow speed, and the rotation speed of the rotating driving member in the driving mechanism is 200-300 rpm, and then enters step S6;

[0046] S4, the control module controls the driving mechanism to run rapidly, and the rotation speed of the rotating driving member in the driving mechanism fast running state is 500-600 rpm, and then enters step S6;

[0047] S5, the control module controls the driving mechanism to stop running, and then enters step S6;

[0048] S6. Enter step S2 loop.

[0049] This embodiment has the following advantages:

[0050] The end of the hose material 81 away from the rotating platform is connected to the cutting station, and the hose material 81 can be pulled and taken out by the equipment of the cutting station or manually. The cutting station and the guide roller mechanism are both located higher than the activity space 16. Therefore, when the cutting station tightens the hose material 81, the hose material 81 can be tightened and swing upward in the activity space 16 to between the upper laser emitter 14 and the upper laser sensor 15. The hose material 81 blocks the laser emitted from the upper laser emitter 14 to the upper laser sensor 15, causing the upper laser sensor 15 to change its sensing signal, thereby enabling the upper sensing unit to sense the hose material 81. When the guide roller mechanism conveys the hose material 81 too fast, the hose material 81 relaxes and swings downward in the activity space 16 under gravity to between the lower laser emitter 23 and the lower laser sensor 24. The hose material 81 blocks the laser emitted from the lower laser emitter 23 to the lower laser sensor 24, causing the lower laser sensor 24 to change its sensing signal, thereby enabling the lower sensing unit to sense the hose material 81, thereby realizing the function of detecting the tightness of the hose material 81 through the tightness detection component.

[0051] By detecting the tightness of the hose material 81, it is determined whether the speed at which the guide roller mechanism conveys the hose material 81 matches the speed at which the hose material 81 is used in the cutting station, and the conveying speed of the hose material 81 by the guide roller mechanism can be dynamically adjusted according to the tightness of the hose material 81, so that the speed at which the guide roller mechanism conveys the hose material 81 and the speed at which the hose material 81 is used in the cutting station maintain a dynamic balance, preventing the guide roller mechanism from conveying the hose material 81 too fast or too slow, thereby preventing the guide roller mechanism from conveying the material too fast and causing the hose material 81 to bend, sag, and accumulate on the ground, thereby preventing the hose material 81 from being entangled with other objects, and preventing the hose mechanism from conveying the material too fast and causing the production efficiency of the cutting station to decrease, thereby realizing the function of automatically adjusting the feeding speed according to the pulling speed of the hose material 81 in the cutting station.

[0052] The inspection component has a simple and reliable structure, detecting the tightness of the hose material 81 without relying on control signals from the cutting station, thereby providing a basis for the control module to adjust the speed of the drive mechanism. In other words, regardless of whether the cutting station uses machine cutting or manual cutting, as long as the cutting station can pull the material according to its material requirements, the hose feeder can adapt to the cutting station. It has good adaptability to various cutting stations and can deliver hose materials 81 to different cutting stations within the factory.

[0053] By vertically sliding the first upper sliding sleeve 12, the second upper sliding sleeve 13, the first lower sliding sleeve 21, and the second lower sliding sleeve 22 on the frame 11, the position height of the upper sensing unit and the lower sensing unit can be adjusted, so that the position height of the activity space 16 can be adjusted, so that it can adapt to cutting stations of different heights.

[0054] When the guide roller mechanism conveys too quickly and causes the hose material 81 to sag between the lower laser emitter 23 and the lower laser sensor 24, the blocking rod 25 blocks the hose material 81 to prevent the hose material 81 from continuing to sag below the lower laser emitter 23 and the lower laser sensor 24, thereby causing the guide roller mechanism to continue conveying the hose material 81, thereby ensuring the reliability of the equipment.

[0055] The lower support block 34 is rotatably connected to a first driven roller 41 and a second driven roller 42. The lower roller shaft 35, the first driven roller 41, and the second driven roller 42 are arranged sequentially along the extension direction of the hose material 81. Three upper roller shafts 33 are provided, located directly above the lower roller shaft 35, the first driven roller 41, and the second driven roller 42. The lower roller shaft 35 is fixedly connected to a first synchronous pulley 43. The first driven roller 41 is fixedly connected to a second synchronous pulley 44 and a third synchronous pulley 45. The second driven roller 42 is fixedly connected to a fourth synchronous pulley 46. A first synchronous belt 47 is wound between the first and second synchronous pulleys 43, 44, and a second synchronous belt 48 is wound between the third and fourth synchronous pulleys 45, 46. When the lower roller shaft 35 rotates, the first driven roller 41 and the second driven roller 42 are simultaneously driven to rotate at the same speed and in the same direction through the first synchronous belt 47 and the second synchronous belt 48. Therefore, the lower roller shaft 35, the first driven roller 41 and the second driven roller 42 can contact the hose material 81 and drive the hose material 81 to move, thereby preventing the hose material 81 from slipping with the guide roller mechanism, and ensuring that the guide roller mechanism can stably transport the hose material 81.

[0056] A screw 36 threadedly connected to the lower support block 34 is inserted through the upper support block 32. A spring 37 is provided between the upper and lower support blocks 32, 34. The screw 36 is inserted through the spring 37, and the ends of the spring 37 are respectively engaged with the upper and lower support blocks 32, 34. The upper support block 32 is lifted upward by the spring 37. Then, the screw 36 is rotated. During the rotation, the screw 36 moves vertically on the lower support block 34, and drives the upper support block 32 to move vertically, thereby adjusting the spacing between the upper roller 33 and the lower roller 35. This allows the upper and lower rollers 33, 35 to clamp hoses of different diameters and adapt to hoses of different diameters.

[0057] The first mounting plate 31 is rotated with a plurality of first guide rollers 38 , which are in contact with the hose material 81 to prevent the material hose from rubbing against the first mounting plate 31 and causing scratches, thereby protecting the hose material 81 .

[0058] The hose material 81 is placed on the material support plate 74. The hose material 81 on the material support plate 74 is spirally wrapped around the outside of the lifting sleeve 63. When the guide roller mechanism pulls one end of the hose material 81 along one end, the hose material 81 rotates due to the pulling force on one side. The material support plate 74, the abutment plate 73 and the slider 72 rotate on the annular guide rail 71, so that the hose material 81 can be unfolded during the rotation process, reducing the resistance encountered by the guide roller mechanism when pulling the hose material 81.

[0059] When the hose material 81 needs to be placed on the material support plate 74, the lifting drive 64 drives the lifting sleeve 63 to move downward, driving the connecting frame 65 and the material support plate 74 to move downward, lowering the height of the material support plate 74, thereby facilitating the transportation of the hose material 81 to the material support plate 74.

[0060] After the material support plate 74 moves downward onto the support column 68, the support column 68 supports the material support plate 74 and continues to drive the lifting sleeve 63, connecting frame 65, and annular baffle 66 downward relative to the material support plate 74. This prevents the lifting sleeve 63 and annular baffle 66 from blocking the hose material 81 during placement onto the material support plate 74, facilitating placement of the hose material 81 onto the material support plate 74. After the hose material 81 is placed onto the material support plate 74, the driving member drives the lifting sleeve 63, connecting frame 65, annular baffle 66, annular guide rail 71, slider 72, and abutment plate 73 upward, causing the abutment plate 73 to engage with the underside of the material support plate 74. The driving member then continues to drive the driving sleeve upward, driving the material support plate 74 and the hose material 81 upward, bringing the height of the hose material 81 closer to the guide roller mechanism, reducing the height difference between the hose material 81 and the guide roller mechanism, and reducing the resistance required by the guide roller mechanism when driving the hose material 81.

[0061] The support ribs 75, outer ribs 76, and inner ribs 77 enhance the structural strength of the material support plate 74. The inner ribs 77 engage the abutment plate 73, providing a position limit for the material support plate 74 and preventing it from sliding horizontally on the abutment plate 73. When the guide roller mechanism stops driving the hose material 81 to move, the inclined nozzle 78 sprays air toward the supporting ribs 75 along the inclined direction, and the air generates thrust on the supporting ribs 75, causing the supporting ribs 75, the material support plate 74 and the hose material 81 to tend to rotate in opposite directions. That is, the rotation direction of the air blown out by the inclined nozzle 78 to drive the supporting ribs 75, the material support plate 74 and the hose material 81 to rotate is opposite to the rotation direction of the guide roller mechanism pulling the hose material 81 to rotate, thereby tightening the hose material 81 between the rotating platform and the guide roller mechanism, preventing the hose material 81 between the rotating platform and the guide roller mechanism from sagging to the ground, preventing the hose material 81 from bending and sagging and accumulating on the ground, and further preventing the hose material 81 from being entangled with other objects.
