Description

Technical Field

[0001] The present invention relates to the field of spinning bobbin collecting, in particular to a bobbin collecting device. Background Art

[0002] After the yarn is wound, it needs to be taken out and replaced with a new yarn bobbin. Generally, textile companies have thousands of yarn bobbins working at the same time. The previous collection method was manual collection by workers, which has low collection efficiency. At the same time, workers use wrist strength to collect quickly for a long time, which causes certain damage to their hands. Although some equipment with collection effects are currently designed on the market, the patent number CN202010693747 disclosed in the prior art is a device for quickly collecting and replacing spinning machine tubes. The defect is that the centripetal force generated by the object during rotation will throw the object out. The faster the rotation speed, the greater the centripetal force. The device cannot determine the landing point of the yarn bobbin, which obviously cannot meet production needs. This also makes it impossible to determine the upper and lower positions of the yarn bobbin during collection, which brings certain difficulties to the later production and processing.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] See also Figure 1-4 .

[0027] The present invention discloses a bobbin receiving device, comprising a device trolley 1 and a first receiving tray 2 and a second receiving tray 3 arranged on the device trolley. The angle between the second receiving tray 3 and the bottom 1 of the trolley is greater than that of the first receiving tray 2. The first receiving tray and the second receiving tray are respectively provided with a plurality of receiving slots 201 and a discharge slot 301 in a circular array. When the trolley is pushed, each of the receiving slots and the discharge slots corresponds to a receiving rod 401 of a spinning machine 4. The receiving slot 201 holds the yarn bobbin on the receiving rod of the spinning machine and transmits the rotation to the discharge slot 301. 1 and then sent out. The upper side of the textile machine is provided with a support plate. The receiving rod 401 can be rotated to pass through the support plate. The function of the support plate is to carry the spinning drum so that it does not contact the bottom equipment. The diameters of the discharge card slot 301 and the receiving card slot 201 are different. The diameter of the yarn drum full of yarn is the smallest, and the yarns at both ends are tapered transition sections. The diameter of the receiving card slot 201 is slightly larger than the diameter of the yarn drum, but smaller than the transition section, and the diameter of the discharge card slot 301 is larger than the maximum diameter of the middle part of the yarn drum. The device trolley 1 is mounted on the There are two sections, namely the material receiving section and the bobbin stacking and loading section; the material receiving section is sequentially provided with a first material receiving tray and a second material receiving tray in the direction of the bobbin stacking and loading section, and an elastic limiting piece 302 is provided on the side of the material discharge slot opposite to its rotation direction, one end of the elastic limiting piece is hinged to the disk surface of the second material receiving tray 3, and a reset torsion spring 3021 is sleeved on the intersection point, and the elastic limiting piece is provided with an arc-shaped groove 3022 with the hinge point as the center of the circle, and the second material receiving tray 3 is provided with a limiting block 303 in the groove 3022, and one end of the reset torsion spring One force arm is fixed on the limit block 303, and the other force arm is close to and fixed on one side of the discharge slot 301. Under normal circumstances, the limit block 303 is at the end of the groove 3022. Under normal circumstances, the gap between the end of the elastic limit piece 302 and the other end of the discharge slot is smaller than the diameter of the yarn bobbin; a collection port 501 is provided on the high point side of the second receiving tray, and a guide is provided between the top of the second receiving tray 3 and the collection port 501; a lifting block 502 is provided at the end of the collection channel below the collection port, and the lifting block pushes the yarn bobbin into the yarn box 6. The rotation of the first and second receiving trays both generate centripetal force that pushes the yarn bobbins outward. When the first receiving tray winds up the yarn bobbins, they are prevented from being thrown out by the receiving rod of the spinning machine. However, when the yarn bobbins are transferred to the second receiving tray and separated from the receiving rod, they are thrown out. The throwing position is uncertain because the centripetal force generated by the worker's pushing speed generates different throwing points. The elastic limiter is set to limit the yarn bobbins transferred to the second receiving tray, so that the yarn bobbins can be smoothly transferred to the collection port.

[0028] The discharge slot 301 is an arc-shaped structure, with the line connecting the center points of the second receiving tray and the discharge slot as the center line A. The side wall of the opening on one side of the elastic limiting piece 302 smoothly opens toward the side away from the center line A, while the other side of the opening is recessed toward the center line. The guide member is an arc-shaped guide rod 7, which is provided above the second receiving tray on the side away from the first receiving tray. The arc-shaped guide rod 7 extends from above the second receiving tray to the outside of the rotation path and is fixed 501 to the collection opening of the collection channel 5. The opening is provided in two forms: the outward-opening side facilitates the smooth guidance of the material to the collection opening under the action of the arc-shaped guide rod, while the recessed side toward the center line acts as a limiter, thereby further controlling the landing position of the yarn bobbin.

[0029] An elastic block 8 is provided on one side of the material collection opening of the material collection channel. Under normal conditions, the elastic limiter passing through the elastic block will be opened by the elastic block. The elastic force of the elastic block is greater than the elastic force of the return torsion spring of the elastic limiter and less than the thrust of the rotation of the second material receiving tray. Before the elastic limiter 302 moves to point B, the elastic limiter 302 contacts the elastic block under normal conditions. During the continued movement, the elastic limiter 302 opens under the action of the elastic block until it reaches point B, where it is fully opened. The yarn bobbin is not subject to the tightening force of the elastic limiter 302 and is pushed into the material collection opening 501 by the action of the discharge slot 301 and the arc-shaped guide rod 7.

[0030] The reason for setting the elastic block to press against the elastic limit plate is that during the actual rotating feeding process, when the material presses against the arc guide rod, as the second receiving tray continues to rotate, the yarn roll gives the elastic limit plate a force to open in the opposite direction under the action of the arc guide rod. This force continues to increase with the continuous dislocation kinetic energy of the elastic limit plate, and when the yarn roll is detached, the retraction of the elastic limit plate will give the yarn roll an additional power, causing it to pop out and uncontrollable direction. Therefore, when it is about to move to the collection port, the elastic limit plate is restricted from opening, and under the action of the open arc side wall on the other side of the discharge slot and the arc guide rod, it can be smoothly introduced from the collection port to the bobbin stacking and loading interval.

[0031] like Figure 5 The contact surface between the elastic block and the elastic limiting plate is an inclined surface. A spring groove 801 is provided on the side of the elastic block 8 opposite to the inclined surface. The elastic block can move back and forth into the spring groove. A spring 802 is provided between the bottom of the spring groove and the elastic block; the spring groove is fixed to one side of the aggregate channel by screws.

[0032] like Figure 4As shown, a receiving plate 9 is provided below the spring slot. Normally, the bottom of the yarn bobbin 10 does not contact the receiving plate 9. However, when the elastic limiting plate opens under the force of the elastic block, the discharge slot loses its vertical limiting force on the yarn bobbin. As a result, the yarn bobbin moves downward about 1 cm, supported by the receiving plate, and guided into the collection port by the discharge slot and the arc-shaped guide rod.

[0033] like Figure 2 、 4 As shown, a guide slope 11 is provided at the material collection opening on one side of the receiving plate, with the highest point of the guide slope being flush with the receiving plate. When the material is pushed and dropped into the collection opening, a small portion of the bottom portion will be on the receiving plate, thus preventing smooth introduction. When the yarn bobbin is poured into the collection opening, its center of gravity slides smoothly into the collection channel under the action of the guide slope.

[0034] like Figure 6 As shown, the aggregate channel 5 includes two parts, namely a vertical part 503 with an aggregate port 501 at the top and an arc-shaped part 504 at the lower end, the side wall height of the vertical part on one side of which the spring groove is provided is lower than the other side; a conveying trough 505 connected to the discharge port of the arc-shaped part is provided on one side of the discharge port, and the conveying trough is 505 lower than the discharge port of the arc-shaped part, and a lifting block 502 for moving up and down is provided at the bottom of the conveying trough, and an aggregate box supporting platform 11 is provided above the conveying trough, and the feed port 601 of the aggregate box 6 corresponds to the top of the conveying trough, and the lifting block is driven by the power device 12.

[0035] A double-door 602 is hinged on both sides of the feed port at the bottom of the collecting box. A reset torsion spring is provided at the hinge of the double-door. Limit blocks are provided at both ends of the feed port at the lower end of the double-door.

[0036] like Figure 7 、 89, the power device includes a linkage turntable 1201, a guide block 1202, a driving gear 1203 and a driven gear 1204; the upper end of the lifting block 502 is an arc-shaped structure that matches the yarn bobbin, and pushing plates 5021 are provided on both sides of the bottom of the lifting block 502. The two pushing plates are provided with longitudinal limiting grooves 1205 facing each other on the outside, and the inner side surfaces facing each other are arc-shaped, with a cylindrical guide block 1202 provided in the middle. The guide block 1202 is provided with a guide groove 12021, and the guide grooves are symmetrically arranged on both sides and spiral upward. The highest point and the lowest point of the guide grooves on both sides are connected, and the pushing plate on one side is provided with a bearing 1206 that slides in the guide groove. The guide block completes the lifting and lowering action by rotating one circle; a driven gear 1204 is coaxially sleeved on the lower side of the guide block, and a driving gear 1203 is provided on one side of the driven gear. The driving gear and the driven gear are driven by a toothed belt, and a linkage turntable is coaxially provided below the driving gear. The circular array of the linkage turntable has a driving slot 12011, which is inserted into the spinning machine receiving rod and corresponds one to one when pushed and rotated. When the driving slot rotates and engages the next spinning machine receiving rod, the driving gear drives the driven gear, and the driven gear completes one circle of rotation, thereby driving the lifting block to complete a material collection and return work; the provided linkage turntable can realize a linkage with the second receiving disc throwing material, so its setting not only reduces the use of the power device, but also strengthens the linkage of the device. When the yarn bobbin is about to be thrown in, the lifting block completes sending a yarn bobbin into the receiving box, and if there is no yarn bobbin at all in the collecting channel, the thrown-in yarn bobbin will be stuck in rotation. Therefore, the collecting channel needs to have a certain number of yarn bobbins, and at the same time realize linkage so that the topmost yarn bobbin is always at a height position each time the second receiving disc throws material.

[0037] like Figure 7 As shown, two sets of limiting wheels 13 are provided at positions corresponding to the grooves on one side of the spinning machine. The rotating shafts of the limiting wheels are fixed on the trolley, and the trolley is provided with driving wheels around it.

[0038] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's description and drawings, or any direct or indirect application in related technical fields, are also included in the patent protection scope of the present invention.
