Description
Technical Field
The invention relates to the technical field of manufacturing of nursing and sanitary products, in particular to an output method of a sanitary product coiled material.
Background
With the increasing living standard, nursing and sanitary articles such as roll paper are widely popularized and used. Since such articles are consumable articles, the amount of use is large, and accordingly, the amount of production is also extremely large, so that the production cost is reduced as much as possible. The manufacture of such articles typically involves: at least one reel for winding the raw material, a processing device for processing the raw material. During production, the processing device pulls the raw material to enable the raw material to gradually withdraw from the winding drum, or the winding drum actively rotates to output the raw material, and the output raw material forms a finished product sheet by sheet or a finished product roll by processes of adding other materials, cutting and the like. When the raw material is completely output, the reel wound with the raw material needs to be replaced by a new reel, and the production can be continuously carried out in such a circulating way.
However, the prior output method of the sanitary product roll has the following technical defects: because the time for replacing the reel is determined according to the rated length of the raw material wound on the reel, the length of the raw material wound on the reel inevitably has certain error with the rated length in the actual production process, and when the actual length is greater than the rated value, the raw material is wasted; when the actual length is less than the rated value, it may cause a production interruption, or cause a failure and waste of the finished product.
Disclosure of Invention
The invention aims to provide an output method of a hygienic product coiled material, which can effectively reduce the waste of raw materials and ensure the normal production and manufacture of finished products.
In order to achieve the purpose, the invention adopts the following technical scheme:
the output method of the sanitary product coiled material comprises at least one coiling block for outputting the coiled material, a manufacturing device for manufacturing the coiled material output by the coiling block into the sanitary product and a control device, and specifically comprises the following steps:
a. the front end part of the coiled material with the original reel is provided with a sensing element, a sensing device capable of sensing the sensing element is arranged in front of the manufacturing device, the coiled material wound on the original reel is wound on the reel, and the sensing element is positioned at the tail end of the coiled material on the reel;
b. when the sensing device senses the sensing element on the coiled material output from the reel, the control device enables the manufacturing device to pause, manually replaces the reel with the coiled material, and then presses the start button to restart the manufacturing device, so that the continuous production of the sanitary products is maintained.
It is known that different sanitary articles need to be made of different types of rolls or other non-roll type materials. The manufacturing plant according to the invention therefore comprises at least one reel for feeding out the web material, a manufacturing device for forming the web material fed out from the reel into sanitary products. Different from the prior art, the invention is provided with the sensing element at the front end part of the coiled material wound on the original reel, and then the coiled material wound on the original reel is rewound on the reel, and the sensing element is positioned at the tail end of the coiled material on the reel, thereby facilitating the arrangement of the sensing element.
It will be appreciated that when the web material is wound on the original reel, we can conveniently place the inductive element at the leading end of the web material; when the web material is wound onto the reel, the inductive element is naturally wound onto the tail end of the web material.
Thus, in step b, when the coiled material on the winding drum is gradually output to the position close to the end of use, the sensing element at the tail end of the coiled material moves to the sensing device, the sensing device senses the sensing element on the coiled material at the moment and then outputs an electric signal to the control device, the control device can pause the manufacturing device, and after the winding drum with the coiled material is manually replaced, the start button can be pressed down to restart the manufacturing device, so that the continuous production of the hygienic products is maintained.
That is, in the present invention, one does not need to precisely control the actual length of the web material, and can accurately know the amount of the remaining web material by sensing the sensing element, thereby timely stopping the manufacturing apparatus and replacing the new roll having the web material.
Preferably, the diameter of the roll is D, the inductive element is a magnet strip affixed to the roll in the axial direction of the roll, the magnet strip is at a distance s from the end of the roll, the length of the roll to the inductive device is L, and 1.2 (L + π D). Ltoreq.s.ltoreq.1.5 (L + π D).
On the one hand, the magnet strip is quite flexible, so that it is convenient to attach it to the coil in the correct position. In particular, the magnetic signal induced by the induction device is facilitated; on the other hand, by properly controlling the relationship between the distance s of the magnet strips to the end of the web and the length L of the web from the reel to the induction device, it can be ensured that the induction device can sense the magnet strips before the web is completely used up and then pause the manufacturing device by the control device.
Due to the inertia of the reel, the manufacturing device, when s < (L + pi D), the remaining coil is liable to come off the reel due to its too short length even if the sensing device senses it. S is more than 1.5 (L + pi D), and although the tail end of the coiled material can be ensured not to be separated from the coiling block all the time, the normal operation of production is maintained, the waste of the tail end of the coiled material is caused.
As an alternative, the roll has a diameter D, the inductive element comprises a foil attached to the tail end of the roll, the foil is provided with a magnet strip extending in the axial direction of the roll, the length of the foil is a, the length of the roll to the inductive device is L, and 1.2 (L + pi D) ≦ a ≦ 2.5 (L + pi D).
In this solution, the sensing element is a film piece connected to the tail end of the roll, and the magnet strip extending along the axial direction of the roll is provided on the film piece, that is, the film piece becomes a part of the tail end of the roll, so we can increase the length a of the film piece appropriately to ensure that the tail end of the roll does not fall off the roll. In addition, the consistency of the distance from the magnet strip to the end of the thin film piece can be ensured.
It should be noted that when the roll is used up, the rest of the film sheet can be used on other rolls, so as to avoid waste.
Preferably, the device further comprises a tension roller which is positioned between the winding drum and the sensing device and can clamp the coiled material, and a position sensor which is close to the winding drum, wherein in the step b, when the coiled material completely falls off from the winding drum, the position sensor senses the fallen coiled material, the control device stops the manufacturing device at the moment, and the manufacturing device is restarted after the winding drum with the coiled material is manually replaced and a start button is pressed.
Because the tensioning roller capable of clamping the coiled material is arranged between the winding drum and the sensing device, even if the final coiled material falls off from the winding drum, the tensioning roller can still enable the moving coiled material to be in a tensioning state, and then normal production of the sanitary product is ensured. Thus, we can shorten the distance s between the magnet strips and the tail end of the coil correspondingly, and then reduce the cost. In step b, whether the coiled material drops from the reel or not is not required to be considered, when the coiled material completely drops from the reel, the position sensor senses the dropped coiled material, the control device pauses the manufacturing device at the moment, and the manufacturing device restarts when the reel with the coiled material is replaced manually and the start button is pressed. That is to say, in this scheme, have dual detection and guarantee to effectual promotion reliability, ensure the normal production of health supplies, furthest reduces loss, the waste of coiled material simultaneously.

When the coiled material passes between last roller, the lower roller and moves forward, can drive roller, lower roller and rotate relatively, rotate the output shaft that the roller can drive DC motor and rotate, DC motor electricity generation to charge for the battery through charging device. That is, the dc motor at this time operates in the generator mode. It will be appreciated that a dc motor operating in generator mode will place a load on the web so that the web between the manufacturing apparatus and the tensioning drum can be maintained in tension at all times and also generate some electrical energy to improve efficiency. In addition, when the coiled material with the winding drum needs to be replaced, the upper winding drum can be driven to rotate positively and negatively by manually driving the rotating handle, and therefore the coiled material is convenient to replace.
Preferably, a driving gear is arranged on a rotating shaft of the upper roller, a driven gear is arranged on an output shaft of the direct current motor, and the transmission ratio of the driving gear to the driven gear is 1/2-1/4.

Detailed Description
The invention is further described with reference to the following detailed description and accompanying drawings.
As shown in fig. 1, an output method of a sanitary product coiled material, the sanitary product comprises a sanitary paper, a sanitary towel, a paper diaper and the like, the manufacturing equipment of the sanitary product comprises at least one coiling block 1 for outputting the coiled material, a manufacturing device 2 for manufacturing the coiled material 9 output by the coiling block into the sanitary product, and a control device, of course, the manufacturing device can also manufacture the coiled material output by the coiling block into the sanitary product together with other materials; alternatively, the manufacturing device can also form the sanitary product together from several different rolls from which the rolls are fed. The method specifically comprises the following steps:
a. the sensing element 3 is arranged at the front end of the coiled material wound on the original reel, then the coiled material wound on the original reel is wound on a production reel, the sensing element is positioned at the tail end of the coiled material on the reel, and a sensing device capable of sensing the sensing element is arranged in front of the manufacturing device. Note that, the side of the manufacturing apparatus close to the roll is referred to as a front side, and the side away from the roll is referred to as a rear side;
b. in the production process of the hygienic products, when the coiled materials on the winding drum are gradually reduced and the sensing device senses the sensing element on the coiled materials output on the winding drum, the control device enables the manufacturing device to pause and send out a corresponding alarm signal, at the moment, an operator can replace the winding drum which is about to get close to the coiled materials, then replace the new winding drum with the coiled materials, reconnect the front ends of the coiled materials on the winding drum, then press the start button to restart the manufacturing device, and the continuous production of the hygienic products can be maintained.
It will be appreciated that the types of webs required may vary from one hygiene article to another and that some may be made from other non-web materials. Since the basic construction of the sanitary article, i.e., the production manufacturing method, is prior art, the present embodiment is not developed in detail.
The present invention creatively provides a sensing element at the leading end of the web material wound on the original reel, and then rewinds the web material wound on the original reel on the reel, while the sensing element is at the trailing end of the web material on the reel. Thus, in step b, when the coiled material on the winding drum is gradually output to the position close to the end of use, the sensing element at the tail end of the coiled material moves to the sensing device, the sensing device senses the sensing element on the coiled material at the moment and then outputs an electric signal to the control device, the control device can pause the manufacturing device, and after the winding drum with the coiled material is manually replaced, the start button can be pressed down to restart the manufacturing device, so that the continuous production of the hygienic products is maintained. That is, by arranging the sensing element, the residual quantity of the coiled material before the coiled material needs to be replaced can be accurately controlled, and then the waste of the coiled material is reduced to the maximum extent.
Preferably, as shown in fig. 2, the diameter of the winding drum is D, the sensing element is a magnet strip adhered to the coil in the axial direction of the coil, and the distance between the magnet strip and the end of the coil is s. That is, the magnet strips are adhered transversely to the web. It will be appreciated that the magnet strip may emit a magnetic field signal and accordingly the sensing means may be a hall element or the like to accurately sense the magnetic field signal of the magnet strip.
Furthermore, with a length L of web material between the reel and the sensing device, we can control the distance s in the following range: 1.2 (L + π D). Ltoreq.s.ltoreq.1.5 (L + π D), so as to ensure that the induction means can sense the magnet strips before the roll has been completely used up, and the production device is then halted by the control means.
The distance s is a distance between the magnet piece and a leading end portion of the web material wound on the capstan, or a distance between the magnet piece and a trailing end portion of the web material wound on the bobbin.
As another preferred option, shown in fig. 3, the roll has a diameter D and the inductive element comprises a membrane 91 attached to the trailing end of the web, the membrane then forming part of the trailing end of the web, the membrane being provided with strips of magnet sheet extending in the axial direction of the web.
Furthermore, the length of the film sheet is a, and the length of the web from the roll to the sensing device is L, the length a of the film sheet can be controlled in the following range: 1.2 A is more than or equal to (L + pi D) and less than or equal to 2.5 (L + pi D).
It should be noted that when the roll is used up, the rest of the film sheet can be used on other rolls, so as to avoid waste. That is, the film sheet provided with the magnet piece strips becomes a standard common part, so that we can suitably increase the length a of the film sheet, ensure that the tail end of the roll does not come off the roll, and ensure the consistency of the distance from the magnet piece strips to the tail end of the film sheet. Of course, the film sheet may be conveniently bonded to the end of the roll.
Further, as shown in fig. 4, the present invention further includes a tension roller 5 disposed between the winding drum and the sensing device, a position sensor, wherein the tension roller is used for clamping the web material to maintain the web material in a tensioned state between the tension roller and the manufacturing device, and the position sensor is used for sensing whether the end of the web material is released from the winding sleeve.
Thus, in step b, when the roll is completely removed from the roll by the last use, the position sensor senses the removed roll, and the control device pauses the manufacturing device, and restarts the manufacturing device when the roll having the roll is manually replaced and the start button is pressed.
Because the tensioning roller capable of clamping the coiled material is arranged between the winding drum and the sensing device, even if the final coiled material falls off from the winding drum, the tensioning roller can still enable the moving coiled material to be in a tensioning state, and then normal production of the sanitary product is ensured. That is, we can shorten the distance s between the magnet strips and the tail end of the roll accordingly, which in turn reduces the cost. In step b, whether the coiled material drops from the reel or not is not required to be considered, when the coiled material completely drops from the reel, the position sensor senses the dropped coiled material, the control device pauses the manufacturing device at the moment, and the manufacturing device restarts when the reel with the coiled material is replaced manually and the start button is pressed.
Preferably, the position sensor is an infrared sensor disposed below the web near the roll, and of course, the infrared sensor includes an infrared transmitting tube and an infrared receiving tube. When the coiled material is used and completely drops from the winding drum at last, the coiled material falls on the infrared sensor, the infrared sensor senses the coiled material approaching after dropping, and then signals are output, at the moment, the control device enables the manufacturing device to pause, and when the winding drum with the coiled material is manually replaced and the start button is pressed, the manufacturing device is restarted.
Finally, as shown in fig. 4 and 5, the tensioning roller comprises an upper roller 51 and a lower roller 52 which are mutually attached, the coiled material passes through the upper roller and the lower roller, one end of a rotating shaft of the upper roller is in transmission connection with an output shaft of a direct current motor 7, the other end of the rotating shaft is provided with a detachable rotating handle 8, and the direct current motor is electrically connected with a storage battery and a charging device. When a new coiled material is replaced and installed, the end part of the coiled material is firstly plugged between the upper roller and the lower roller, then the rotating handle is rotated to drive the upper roller and the lower roller to rotate, and then the coiled material is brought between the upper roller and the lower roller. When the production of the sanitary products is formally started, the moving coiled material drives the upper roller and the lower roller to relatively rotate, then the output shaft of the direct current motor is driven to rotate, the direct current motor generates electricity (the direct current motor is in a generator mode at the moment), and the storage battery is charged through the charging device.
Furthermore, a driving gear 511 is arranged on a rotating shaft of the upper roller, a driven gear 521 is arranged on an output shaft of the direct current motor, and the transmission ratio of the driving gear to the driven gear is 1/2-1/4, so that the rotating speed of the output shaft of the direct current motor is increased, the generated energy is increased, the load is increased, and the tension of the coiled material is ensured.
It should be noted that, both ends of the rotating shaft of the lower roller are rotatably supported on the bearing seats 53 at both ends, the upper side of the bearing seat is provided with a vertical slot 531, and the rotating shafts at both ends of the upper roller are respectively located in the slots at the corresponding end. Therefore, the upper roller can normally rotate and tightly cling to the lower roller under the action of self gravity, and even if the thickness of the coiled material slightly changes, the upper roller can tightly cling to the lower roller with the same acting force all the time and extrude the coiled material.
Of course, the weight of the upper roller and the extrusion force of the coiled material can be controlled by reasonably setting the diameters and the materials of the upper roller and the lower roller.
