Description

Technical Field

[0001] The invention belongs to the technical field of automatic feeding of yarn bobbins, and in particular relates to an automatic feeding device for yarn bobbins with tail yarns. Background Art

[0002] The yarn tube is the main component for winding yarn. There will usually be residual yarn tails on the used yarn tube, forming yarn tubes with yarn tails. Before processing, these yarn tubes are mostly piled up in a corner or collection box, and they need to be taken out one by one to deal with the residual yarn tails. The traditional way of taking them out is manual, which is time-consuming, labor-intensive and inefficient, and it is difficult to cooperate with automatic yarn tail removal equipment for feeding.

[0003] In addition, when the yarn bobbins with tail yarns are piled up, the tail yarns on adjacent yarn bobbins tend to be entangled with each other. When one of them is taken out, the entangled yarn will bring out the other one, which may easily lead to abnormal feeding of the automatic tail yarn removal equipment. Summary of the invention

[0032] like Figures 1 to 6As shown, the automatic feeding device for yarn bobbins with tail yarns provided by the present invention comprises a base 10, a storage box 20, a guide plate 30, and a barrel block, wherein the base 10 is a frame-type base, the storage box 20 is used for stacking yarn bobbins with tail yarns, the storage box 20 is arranged on the base 10, and its top is open to form an opening 21, and a bottom plate 22 is provided at the bottom of the storage box 10, and the bottom plate 22 extends obliquely downward from the back to the front, and the rear edge of the bottom plate 22 is connected to the bottom of the storage box 10, and a notch 23 is provided in front of the bottom plate 22; the guide plate 30 is connected to the front edge of the opening 21 and extends obliquely forward and downward, and the front edge of the guide plate 30 is connected to the feeding port of the automatic tail yarn removal device (not shown in the figure); the barrel block is connected to the storage box The inner walls of both sides of 10 are symmetrically arranged on the left and right sides of the notch 23, the barrel block extends in the up-down direction, the upper end surface of the barrel block extends downwardly from the back to the front, the inclination degree of the upper end surface of the barrel block is the same as the inclination degree of the bottom plate 22 and is greater than or equal to the inclination degree of the guide plate 30; specifically, the barrel block includes a plurality of fixed barrel blocks 41 and a plurality of movable barrel blocks 42, the movable barrel blocks 42 are staggered with the fixed barrel blocks 41, and the barrel blocks located at the front and rear are both movable barrel blocks 42; the movable barrel block 42 has an upper working position and a lower working position, and when the movable barrel block 42 is in the upper working position, the front edge of the upper end surface of the movable barrel block 42 is aligned with the fixed barrel block in front of the movable barrel block 42 The rear edge of the upper end surface of the barrel block 41 is flush with each other, and the front edge of the frontmost movable barrel block 42 is flush with the rear edge of the guide plate 30. When the movable barrel block 42 is in the lower working position, the rear edge of the upper end surface of the movable barrel block 42 is flush with the front edge of the upper end surface of the fixed barrel block 41 behind the movable barrel block 42, and the rear edge of the rearmost movable barrel block 42 is flush with the front edge of the bottom plate 22. In this way, the movable barrel block 42 can lift the yarn tubes accumulated on the bottom plate 22 in sequence by moving up and down until they roll onto the guide plate 30; further, the guide plate 30 is also provided with a dividing rod 31 which can be moved up and down, and the dividing rod 31 extends in the up and down direction, and the dividing rod 31 has two and corresponds to the guide plate 30. The two side edges are arranged, the spacing between the two dividing rods 31 is larger than the width of the tail yarn on the yarn bobbin and smaller than the length of the yarn bobbin, and an electric heating strip 32 is mounted on the upper ends of the two dividing rods 31. When the dividing rod 31 moves downward to the extreme position, the electric heating strip 32 is attached to the upper surface of the guide plate 30, and the yarn bobbin on the guide plate 30 can smoothly roll into the feeding port. When the dividing rod 31 moves upward to the extreme position, the yarn bobbin behind the dividing rod 31 on the guide plate 30 is blocked and separated from the yarn bobbin in front, and the electric heating strip 32 burns off the tail yarn entangled between the two yarn bobbins during the movement of the dividing rod 31, thereby realizing the anti-entanglement function. The automatic feeding device has a sophisticated structure, significant effect, low cost, and is easy to promote and use.

[0033] For the convenience of setting, in the present embodiment, the dividing rod 31 is movably arranged up and down on the material guide plate 30. Furthermore, the up and down movement of the dividing rod 31 is synchronized and reversed with the up and down movement of the movable baffle block 42. The synchronization means that when the movable baffle block 42 moves, the dividing rod 31 also moves. The reverse direction means that when the movable baffle block 42 moves upward, the dividing rod 31 moves downward, and when the movable baffle block 42 moves downward, the dividing rod 31 moves upward.

[0034] In this embodiment, an I-shaped connecting plate 43 is provided below the notch 23, and the I-shape means that the projection of the connecting plate 43 in the up and down direction is an I-shape, and the two cross bars of the connecting plate 43 are connected to the lower ends of all the movable baffle blocks 42, and the middle part of the longitudinal bar of the connecting plate 43 is connected to a first vertical rod 431 extending downward; a cross beam 33 extending in the left and right direction is provided below the guide plate 30, and the two ends of the cross beam 33 are connected to the lower ends of the two material dividing rods 31, and the middle part of the cross beam 33 is connected to a second vertical rod 331 extending downward. At the same time, a first transmission rod 11 and a second transmission rod 12 are provided on the base 10, and the first transmission rod 11 extends in the left and right direction, and the middle part of the first transmission rod 11 is rotatably connected to the base 10 On, the rotation axis line of the rotation extends horizontally along the front-to-back direction, the left end of the first transmission rod 11 is rotationally and slidingly connected to the output end of the driving mechanism 13, and the right end of the first transmission rod 11 is rotationally and slidingly connected to the lower end of the first vertical rod 431; the second transmission rod 12 extends along the front-to-back direction, and the middle part of the second transmission rod 12 is rotatably connected to the base 10, and the rotation axis line of the rotation extends horizontally along the left-to-right direction, the rear end of the second transmission rod 12 is rotationally and slidingly connected to the right end of the first transmission rod 11, and the front end of the second transmission rod 12 is rotationally and slidingly connected to the lower end of the second vertical rod 331. The rotational sliding connection can be achieved by the cooperation of the waist-shaped hole and the cross piece inserted in the waist-shaped hole, which will not be repeated here.

[0035] The advantage of such a setting is that it can not only realize the synchronous reverse movement of the above-mentioned dividing rod 31 and the movable barrel block 42, but also enable the first transmission rod 11 and the second transmission rod 12 to form a lever structure, so as to adjust the amplitude of the up and down movement of the dividing rod 31 and the movable barrel block 42 and the force distance for driving the dividing rod 31 and the movable barrel block 42 to move up and down, so as to adapt to yarn bobbins with tail yarns of different models and different tail yarn thicknesses.

[0036] In this embodiment, the driving mechanism 13 is fixed on the left side of the base 10. In order to control the rhythm of driving the material dividing rod 31 and the movable stopper block 42 to move up and down, the driving mechanism 13 is a combination of a stepping motor and a screw pair.

[0037] Since the diameters of yarn tubes of different models are different, in order to further improve the applicability of the automatic loading device, in this embodiment, the front edge of the upper end surface of the barrel block is connected to an extension plate 44 extending forward and downward, and the inclination degree of the extension plate 44 is the same as the inclination degree of the upper end surface of the barrel block. The total length of the upper end surface of the barrel block and the upper surface of the extension plate 44 in the front-to-back direction is 1.1 to 1.9 times the diameter of a single yarn tube, and the extension plate 44 is integrally formed with the barrel block where it is located.

[0038] To ensure that the yarn tube rolls smoothly on the guide plate 30, further, the guide plate 30 has flanges 34 folded upward vertically on both sides, and the feed rod 31 is located on the inner side of the flange 34. When the yarn tube rolls on the guide plate 30, the flange 34 is used to flatten the end face of the yarn tube.

[0039] To facilitate material replenishment, in the present embodiment, the opening 21 is lower at the front and higher at the back, and the plane where the edge of the opening 21 is located is the same plane as the plane where the material guide plate 30 is located.

[0040] It should be noted that in order to facilitate the smooth rolling of the yarn tube on the guide plate 30 with a moderate rolling speed, the inclination of the guide plate 30 (the angle between the plane where the guide plate 30 is located and the horizontal plane) is preferably controlled at 5 to 15 degrees. Specifically in this embodiment, the inclination is 10 degrees.

[0041] Similarly, in order to facilitate the lifting of the yarn bobbin and maintain a moderate lifting efficiency, the inclination between the upper end surface of the bobbin block and the bottom plate 22 is preferably controlled at 15 to 25 degrees. Specifically in this embodiment, the inclination is 10 degrees.

[0042] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
