Description

Full-automatic waste discharge device and full-automatic waste discharge method

Technical Field

The invention relates to waste discharge of self-adhesive labels, in particular to a waste discharge device and a waste discharge method.

Background

The self-adhesive label 202 is also called self-adhesive label material (or self-adhesive label), and is a composite material which uses paper, film or special material as face material, and its back surface is coated with adhesive, and its silicon-coated protective paper is used as base paper. The adhesive coated facestock is used as a final product for attachment to a package.

In the production process of the self-adhesive product, the self-adhesive product is generally subjected to die cutting and molding in a required shape, waste materials (namely label waste materials 205) outside the required shape are discharged and collected, and the rest materials are formed products (main materials, namely finished products 204) and delivered to end customers for use, as shown in fig. 1, and when the self-adhesive product is used, the self-adhesive product is generally used in an automatic labeling mode.

The waste materials in the adhesive sticker production process are generally collected in a winding drum manner, which can also be called winding collection. When the diameter of the coil is increased, the equipment needs to be stopped and replaced so as to coil and collect the coil again. This is not only common but also quite inefficient, and the downtime does not meet the requirement of automation production operation with high efficiency. As a demand for automation, there is also an automated collection method, for example, extraction is performed under negative pressure, rolling cutting is performed, and full-automatic collection is completed (hereinafter, referred to as "air draft waste discharge").

The air draft waste discharge has the obvious defects and shortcomings that: when the negative pressure air extracts the waste material, the extracted waste material obviously rolls, and the extraction force of the negative pressure air fluctuates and changes in the rolling process, obviously, the extraction force corresponds to the tension acting on the waste material, and the fluctuating and changed extraction force corresponds to the fluctuation and change of the tension. Since the scrap consists of the remainder of the desired shape after die cutting, the more compact the desired shape is theoretically aligned with the desired shape, the more cost effective. Since the desired shape is arranged in a compact manner, the maximum tension experienced by the surface of the material is smaller, and the tension of the wound up scrap is smaller in actual production. Tension fluctuation and change generated by the rolling phenomenon during negative pressure air extraction can easily cause the material breaking phenomenon of the waste materials. Particularly when the brittle material or the shaped mark is used, the higher the sensitivity to tension, the more easily the brittle material is broken, and the failure of the production is caused. The defects of suspended waste exposed in the air and easy material breakage exist in air draft waste discharge.

It is clear that the waste in the hanging path, especially the most pronounced in the profile shape, is seen in fig. 2, i.e. the weak point of the waste in the traveling seed becomes very easily stretchable due to the tension, while the stretched waste becomes narrower and narrower than the actual material width, the more pronounced and sensitive the weak point of the waste, fig. 3.

Both of the above approaches cannot be addressed, particularly the extremely sensitive tensile characteristics of irregularly shaped scrap. The shaped scrap shown in fig. 1 is broken because when the weakest point of the shaped scrap is usually the most variable position in the run, the surface tension of the material is changed greatly, the weak point is often the most easily stretched, and all applied tension on the whole scrap surface is concentrated at the weak point.

The length of a unit of a common finished product of the self-adhesive label is at least 50mm, generally speaking, the larger the shape of the finished product is, the larger the shape change of the finished product is (such as a special shape), the hollow parts on the stripped waste correspond to the finished product, and the waste discharge difficulty of the self-adhesive label is also higher. If the length specification of the finished product unit of the self-adhesive label is less than 50mm, the finished product unit can be arranged and combined in a plurality of rows for economy. The more the array, the less difficult the waste discharge in general. If the finished product unit length specification is smaller, more rows can be arranged, the more waste discharge pulling points are arranged, otherwise, the larger the finished product unit length specification is, the fewer the rows are arranged, and the fewer the waste discharge pulling points are arranged; in addition, the larger the specification is, the larger the length-width ratio of the shape is, or the more irregular the shape is, the greater the waste discharge difficulty is, and the more difficult the waste discharge difficulty is relatively smaller and the shape is not easy to break. The waste discharging difficulty is high, the waste is easy to break, the waste is called as the waste of the self-adhesive label with the easy-to-break specification, such as the waste of the self-adhesive label with special shape, large size and the like, and the hollow edge of the waste is easy to break.

When the inert rollers are arranged more than two, the inert rollers are sequentially connected, and the third feeding distance between the two inert rollers is smaller than or equal to the hollowed-out length of the adhesive label waste with the breakable specification. When more than two inert rollers are used, the hollow parts of single self-adhesive label waste materials with the breakable specifications can be always dragged in the inert roller mechanism, and the hollow parts of the single self-adhesive label waste materials with the breakable specifications cannot be completely in a suspended state.

In addition, the inert roller of inert roller mechanism sets up one or more than two (contain two), has seted up the ring channel on the cylinder face of scraper roller, and the ring channel is followed axial direction align to grid on the cylinder face of scraper roller, can reduce the area of contact of label waste material and scraper roller, scrapes the shovel more easily to reduce the heat that the scraper roller produced during scraping the shovel, the heat dissipation is better. A water cooling channel or an air cooling channel is arranged in the scraper roller, so that the temperature of the scraper roller can be reduced and cooled. The phenomenon that the heat causes the adhesive of the non-setting adhesive to melt so as to influence the normal use of the scraper roller is avoided. The front side and the rear side of the stripping roller are respectively provided with a transition roller for arranging the adhesive sticker in a matching way and stripping the waste materials separately, so that the structure is more reasonable. The scraper is at least provided with one, the scraper can be matched with the label waste on the scraper roller to scrape off, and a plurality of scrapers can peel off the hot melt adhesive with stronger viscosity. The side of the scraper roller is also provided with a material receiving platform, and the label waste materials scraped off by the scraper roller are received and collected by the material receiving platform. Wherein, the tension control device comprises a low-friction cylinder or an ultra-low friction cylinder or an extension spring or a compression spring or a torsion spring or a counterweight cable; the floating frame is arranged in a linear floating mode or in a swinging floating mode.

In order to solve the technical problems, the invention also adopts the following technical scheme: the full-automatic waste discharge method comprises the steps of separating and peeling off the label waste of the self-adhesive sticker and a finished product at a peeling roller, continuously conveying the finished product after the label waste is separated and peeled off, discharging waste on a scraper roller after the label waste is separated and peeled off, and scraping the waste by abutting a scraper on the roller surface of the scraper roller during waste discharge; the label waste is moved by the cooperation of the inert roller between the peeling roller and the scraper roller, after the label waste is separated from the peeling roller, the non-adhesive surface of the label waste moves around the inert roller, the adhesive surface of the label waste after the label waste bypasses the inert roller is wound around the scraper roller, and the label waste on the scraper roller is scraped by the scraper; the first feeding suspension length of the label waste between the stripping roller and the inert roller and the second feeding suspension length of the label waste between the inert roller and the scraper roller do not exceed the hollow length of the self-adhesive label waste with the breakable specification. According to the method, the scraper roller, the stripping roller and the inert roller of the inert roller mechanism are matched, so that continuous waste discharge without shutdown is realized, hollow parts of single self-adhesive label waste materials can be always dragged, the hollow parts of the single self-adhesive label waste materials cannot be completely suspended, the label waste materials are not prone to being broken, the continuous waste discharge effect is better and more stable, the material discharge is smoother, and the waste discharge operation without shutdown is realized.

The following optimization or supplementary explanation can be performed on the technical scheme.

For example, the first sensor detects the signal of the running speed of the label of the self-adhesive sticker before separation and peeling, and the first sensor feeds back and controls the power motor to control the rotating speed of the scraper roller after detecting the signal.

The second sensor detects a position signal of the floating inert roller or a floating frame for mounting the floating inert roller, and the second sensor feeds back and controls the power motor to control the rotating speed of the scraper roller after detecting the signal. The position of the floating frame or the inert roller is sensed in real time by the second sensor, so that the rotating speed of the scraper roller driven by the power motor is controlled in a matched mode, synchronous control is further realized in a matched mode, the scraper roller is enabled to run synchronously in real time and accurately, and the automation degree is higher.

When more than two inert rollers are arranged, the label waste is sequentially wound around the inert rollers to operate, wherein the third feeding suspension length of the label waste between the two inert rollers is less than or equal to the hollow length of the adhesive label waste with the breakable specification. When more than two inert rollers are used, the hollow parts of single self-adhesive label waste materials with the breakable specifications can be always dragged in the inert roller mechanism, and the hollow parts of the single self-adhesive label waste materials with the breakable specifications cannot be completely in a suspended state.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention; it should be apparent that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work based on the embodiments of the present invention belong to the protection scope of the present invention.

Referring to the drawings, in the embodiment, the full-automatic waste discharge device includes a doctor roll 206, a peeling roll 203 and an idler roll mechanism. The scraper roller 206 is connected to a power motor in a driving manner, and the scraper roller 206 is driven by the power motor (e.g., a servo motor) to rotate. The waste label 205 and the finished product 204 on the peeling roller 203 are peeled off separately by the adhesive 202 label, the waste label 205 and the finished product 204 of the adhesive 202 are peeled off separately, the hollow position of the waste adhesive label 205 is the position of the finished product 204, and the hollow length is the length of the adhesive 202 in the advancing direction, namely the length of the finished product 204. A scraper 401 is arranged on the roll surface of the scraper roll 206, and the scraper 401 can be matched with the roll surface of the scraper roll 206 so as to scrape and remove the label waste 205 with the adhesive surface attached to the scraper roll 206. An idler roller mechanism is disposed between the doctor roller 206 and the peel roller 203, wherein the idler roller mechanism includes at least one idler roller 301, the idler roller 301 is disposed in engagement between the doctor roller 206 and the peel roller 203, and the idler roller 301 is rotated to engage the cooperating label waste 205 for feeding operation. The label waste 205 is separated from the peeling roller 203, enters from the inlet end of the idler roller mechanism, is output from the outlet end of the idler roller mechanism, the label waste 205 is wound around at least one idler roller 301 in the idler roller mechanism and is output, the output label waste 205 is pasted on the scraper roller 206, and is scraped off along with the rotation of the scraper roller 206 to the scraper 401. The doctor roll 206, the peeling roll 203 and the inert roll 301 are arranged in parallel, and the layout is reasonable.

A first feeding distance is reserved between the inlet end of the inert roller mechanism and the peeling roller 203, the label waste 205 is positioned in a path of the first feeding distance between the peeling roller 203 and the inert roller mechanism, a second feeding distance is reserved between the outlet end of the inert roller mechanism and the scraper roller 206, the label waste 205 is positioned in a path of the second feeding distance between the inert roller mechanism and the scraper roller 206, the label waste 205 respectively passes through the first feeding distance and the second feeding distance in the running (advancing and moving) process, and the parts of the label waste 205 at the first feeding distance and the second feeding distance are in a suspended state.

The structure of this full-automatic waste discharging device is succinct relatively, compact, can realize not shutting down continuous waste discharging, and its continuity waste discharging effect is better, can continuously carry out label waste 205 and get rid of, need not carry out the waste material change of lap at the waste discharging in-process, and efficiency is higher.

On the basis, the first feeding distance and the second feeding distance are respectively smaller than or equal to the hollow length of the adhesive label waste 205 with the fragile specification. In the moving process of the self-adhesive label waste 205 (the self-adhesive label waste 205 for short) with the breakable specification, a single hollow part of the self-adhesive label waste 205 passing through the first feeding distance or the second feeding distance cannot be completely in a suspended state, the head or the tail of the single hollow part can be supported and supported by the stripping roller 203 or the inert roller 301 or the scraper roller 206 and cannot be completely in the suspended state, and the self-adhesive label waste 205 can be relatively flattened and is not easy to break. The lengths of the first feeding distance and the second feeding distance are adjusted, and the set length is adjusted to ensure that the adhesive label waste 205 is not easy to break. After the tag waste 205 and the finished product 204 are peeled off, the waste in the path of each feeding distance is exposed in the air in a very sensitive suspension manner, and the waste is easy to break in the suspension path, which is not beneficial to continuous material collection. In fact, the waste discharge of the scraper 401 and the exhaust waste discharge have the defects that waste is suspended and exposed in the air and the material is easy to break.

This full-automatic waste discharge device's structure is succinct relatively, compact, scraper roller 206, peel off roller 203 and the cooperation structure of the inertia roller 301 of inertia roller mechanism can drag the fretwork department that attaches (holds) single adhesive label waste material 205 of the single easy-to-break specification all the time, can not let the fretwork department of that kind of single adhesive label waste material 205 of easy-to-break be in unsettled state completely, the head or the tail of single fretwork part can be held the support, label waste material 205 is difficult for the material that breaks, its continuity waste discharge effect is better, it is more stable, it is more smooth to arrange the material, so that realize not shutting down and arrange waste operation. Of course, the full-automatic waste discharge device is also suitable for discharging the adhesive label waste 205 which is regular, small in size, multi-column unit and not easy to break.

As shown in fig. 7, assuming that the length specification of the finished products 204 is 50mm as an example, each hollowed-out length of each corresponding finished product 204 is 50mm, the first feeding distance between the inlet end of the inert roller mechanism and the peeling roller 203 is 20mm, when the 50mm length specification of the hollowed-out portion is not completely peeled off and suspended, the front end hollowed-out portion is already attached to the roller surface of the inert roller 301 of the inert roller mechanism, the dragging and attaching effect of the roller surface of the inert roller 301 on the label waste 205 is already generated, and the hollowed-out label waste 205 is not completely suspended and exposed in the air, so that the risk of material breakage is not generated. When the empty label waste 205 leaves the inert roller mechanism by 20mm, the empty label waste is contacted with the roller surface of the scraper roller 206, the structure is compact, and the aim is to ensure that the empty length of 50mm is in a dragged state, but the empty single adhesive sticker 202 is not allowed to be completely suspended in the air.

The following optimization or further explanation can be made on the basis of the above embodiment.

For example, the fully automatic waste discharge device further comprises a first sensor 50, and the first sensor 50 is used for detecting the running speed signal of the label of the non-setting adhesive 202 before being peeled. The first sensor 50 may be an encoder such as a code wheel type sensor, and if the first sensor 50 has other specific products as far as possible, the first sensor 50 may be directly disposed at the peeling roller 203. The first sensor 50 is connected with the power motor, and senses the running speed of the adhesive sticker 202 label in real time by using the first sensor 50 so as to be matched with the power motor to control the rotating speed of the scraper roller 206 driven by the power motor, so that the linear speed of the scraper roller 206 can be matched with (i.e. synchronized with) the running speed of the adhesive sticker 202 label, and the synchronous control is realized by matching, so that the scraper roller 206 can accurately track and run synchronously in real time, and further automatic operation is realized.

For example, as shown in fig. 5, when the adhesive sticker 202 rotates for 1 pulse through the peeling roller 203, the first sensor 50 feeds back a signal to an upper computer (such as a computer, a PLC, or a single chip microcomputer) in real time, the power motor of the scraper roller 206 is controlled by the upper computer, and the instant reaction is performed, so that the purpose of synchronously conveying the scraper roller 206 and the peeling roller 203 is achieved through the virtual gear ratio principle and the corresponding number of rotating pulses.

To explain further, one of the inert rollers 301 is provided; or when more than two idler rollers 301 are provided. When more than two inert rollers 301 are arranged, the inert rollers 301 are sequentially connected, and the third feeding distance between the two inert rollers 301 is smaller than or equal to the hollow-out length of the self-adhesive label waste 205 with the breakable specification. When the inert rollers 301 are more than two, the hollow parts of the single self-adhesive label waste 205 with the breakable specification can be always dragged in the inert roller mechanism, and the hollow parts of the single self-adhesive label waste 205 with the breakable specification can not be completely in a suspended state. The structure is most compact when the idler rollers 301 are arranged one by one. Wherein, the roller surface of the inert roller 301 can be additionally processed in an anti-sticking way, such as Teflon processing, so that the adhesive surface of the label waste 205 can be wound by some inert rollers 301 to run more smoothly.

Optimization is also possible, wherein at least one inert roller 301 is arranged on the floating frame 30, that is, at least one inert roller 301 in the inert roller mechanism is arranged on the floating frame 30, some inert rollers may not be arranged on the floating frame 30, and certainly, a plurality of floating frames 30 can be arranged for different inert rollers 301; in addition, a tension control device is connected to the floating frame 30. The floating frame 30 is matched to float (move back and forth), the floating of the general floating frame 30 is a micro-motion, and a limit structure (such as a limit block) can be arranged to limit the floating range of the floating frame 30. The tension control device is matched to keep the tension stable, the label waste 205 wound on the inert roller 301 keeps the tension relatively stable, the label waste 205 runs under the state of keeping the stable tension, and the label waste 205 is ensured not to be easily broken. Meanwhile, the running speed between the scraper roller 206 and the peeling roller 203 before and after the inert roller 301 can be compensated, and when the scraper roller 206 and the peeling roller 203 are inconsistent and asynchronous, the running speed is compensated through floating, so that the synchronization is realized. For example, the idler roller 301 will float to compensate when there is an accumulated error inherent in the equipment during continuous production. The inert roller 301 can compensate the speed and the tension, the inert roller 301 has a slight amount of floating, in the floating range, the first feeding distance (between the peeling roller 203 and the inert roller 301) and the second feeding distance (between the inert roller 301 and the scraper roller 206) do not exceed the hollowed-out length of the adhesive sticker label waste 205 with a fragile specification, and the effect of the adhesive sticker label waste 205 is more obvious when the hollowed-out specification of the label waste 205 is larger. The function of doctor roll 206 is to accomplish a continuous, uninterrupted scraping of waste material. Even if the adhesive label waste 205 is in a floating state, the first material conveying distance and the second material conveying distance are respectively less than or equal to the hollow length of the adhesive label waste 205 with the fragile specification.

Wherein, the tension control device comprises a low-friction cylinder or an ultra-low friction cylinder or an extension spring or a compression spring or a torsion spring or a counterweight cable and the like; the floating frame 30 is linearly arranged in a floating manner or arranged in a swinging manner, the linear floating can be arranged on a linear guide rail, and the linear floating direction can be vertical, horizontal or oblique; the oscillating float may be provided on an oscillating arm, the oscillating shaft of which may be provided on the frame 10 alone or coaxially with the doctor roll 206 or with the peeling roll 203, see fig. 5, 6, 10.

It is further preferred that the floating frame 30 is equipped with a second sensor (not shown) for detecting a position signal of the floating frame 30 or of the idler roller 301 on the floating frame 30, which second sensor is coupled to a power motor. The position of the floating frame 30 or the inert roller 301 is sensed in real time by using a second sensor (such as an encoder or a potentiometer) so as to be matched with the control of the rotating speed of the scraper roller 206 driven by the power motor, and further matched with the control to realize synchronous control, so that the scraper roller 206 is synchronously tracked in real time and accurately, and the automation degree is higher. For example, as shown in fig. 5, the inert roller 301 will jog (i.e., float) to the right or left, when the inert roller 301 is to the left, the second sensor will feed back a signal to an upper computer (such as a computer, a PLC, or a single chip microcomputer, etc.) in real time, and the power motor of the scraper roller 206 should reduce a certain pulse amount during production, conversely, when the inert roller 301 is to the right, the power motor of the scraper roller 206 should increase a certain pulse amount during production, and this compensation pulse amount will make the inert roller 301 float at a relative equilibrium position; the position of the idler roller 301 is sensed by the second sensor, and when the idler roller 301 floats and deviates from the corresponding position, the rotating pulse quantity of the power motor can be reduced or increased in a matched mode, so that the rotating speed of the power motor can be changed.

In addition, supplementary optimization shows that the inert roller 301 of the inert roller mechanism is provided with one or more than two (including two), see fig. 5, 6, and 8 to 10, the roller surface of the scraper roller 206 is provided with annular grooves, the cross sections of the annular grooves can be in a triangular or square-angle shape, and the annular grooves are uniformly arranged on the roller surface of the scraper roller 206 along the axial direction, so that the contact area between the label waste 205 and the scraper 401 and the scraper roller 206 can be reduced, scraping is easier, heat generated by the scraper roller 206 is reduced during scraping, and heat dissipation is better. A water cooling channel or an air cooling channel is arranged in the scraper roller 206, water or ventilation can be used for cooling, a water source or an air source can be connected through a rotary joint, and the temperature of the scraper roller 206 can be reduced and cooled; the phenomenon that the heat causes the adhesive of the adhesive sticker 202 to melt, which affects the normal use of the scraper roller 206, is avoided. The front side and the rear side of the stripping roller 203 are respectively provided with a transition roller 201 which is used for arranging the adhesive sticker 202 to bypass and convey and separating and stripping waste materials, and the structure is more reasonable. Doctor blade 401 scrapes against doctor roller 206 and doctor blade 401 may be adjusted to adjust the spacing from doctor roller 206. Scraper 401 disposes one at least, and scraper 401 can cooperate and scrape the label waste material 205 on the scraper roller 206 and shovel down, and many scraper 401 (more than two) then can peel off stronger viscous hot melt adhesive, and the adhesive of non-setting adhesive 202 has a variety, and it is common for waterborne adhesive and hot melt adhesive, and when adopting the hot melt adhesive, many scraper 401 can peel off the operation to stronger viscous hot melt adhesive. The scraper roller 206 is further provided at a side thereof with a receiving platform 101, the scraped label waste 205 is received and collected by the receiving platform 101, the receiving platform 101 is movably disposed (for example, slidably disposed), or the receiving platform 101 is disposed to convey the receiving platform 101, and the scraper roller 206 has a conveying structure (for example, a conveying belt or a conveying roller) to collect and convey the scraped label waste 205.

The embodiment also provides a full-automatic waste discharge method corresponding to the full-automatic waste discharge device. The full-automatic waste discharge method comprises the steps that label waste 205 of adhesive sticker 202 and finished products 204 are separated and peeled off at a peeling roller 203, the separated and peeled finished products 204 are conveyed continuously, the separated and peeled label waste 205 is discharged on a scraper roller 206, and a scraper 401 abuts against the roller surface of the scraper roller 206 to scrape during waste discharge; the peeling roller 203 and the scraper roller 206 are matched with each other by an inert roller mechanism to move, the label waste 205 moves around the inert roller 301 of the inert roller mechanism after the label waste 205 is separated from the peeling roller 203, the adhesive surface of the label waste 205 after the label waste 205 passes around the inert roller 301 is attached to the scraper roller 206, the scraper roller 206 carries and pulls the label waste 205, and then the scraper 401 scrapes the label waste 205 on the scraper roller 206; the inert roller mechanism is at least provided with one inert roller 301 (such as one or more than one inert rollers), the inlet end of the inert roller mechanism is used for the label waste 205 to enter, the label waste 205 is discharged from the outlet end of the inert roller mechanism, and the inert roller mechanism is matched and connected between the stripping roller 203 and the scraper roller 206 and is matched for carrying out the waste discharge operation movement of the label waste 205; wherein, the first feeding suspension length of the label waste 205 between the stripping roller 203 and the inlet end of the inert roller mechanism and the second feeding suspension length of the label waste 205 between the outlet end of the inert roller mechanism and the scraper roller 206 do not exceed the hollow length of the self-adhesive label waste 205. In the moving process of the self-adhesive label waste 205 (the self-adhesive label waste 205 for short) with the breakable specification, a single hollow part of the self-adhesive label waste 205 passing through the first feeding distance or the second feeding distance cannot be completely in a suspended state, the head or the tail of the single hollow part can be supported and supported by the stripping roller 203 or the inert roller 301 or the scraper roller 206 and cannot be completely in the suspended state, and the self-adhesive label waste 205 can be relatively flattened and is not easy to break.

This full-automatic waste discharge method, by scraper roller 206, peel off roller 203 and the inert roller 301 of inert roller mechanism cooperate, can realize not shutting down the waste discharge, continuous waste discharge, on this basis, wherein can drag the fretwork department of single adhesive label waste material 205 all the time, can not let the fretwork department of single adhesive label waste material 205 be in unsettled state completely, the difficult disconnected material of label waste material 205, its continuity waste discharge effect is better, more stable, arrange the material more smoothly to realize not shutting down the waste discharge operation. But also applies to the waste discharge of the adhesive label waste 205 which is regular, small in size, multi-column unit and not easy to break.

The following optimization or further explanation can be made on the basis of the above embodiment.

For example, a signal indicating the label running speed of the pressure sensitive adhesive 202 before separation and peeling is detected by the first sensor 50, and the first sensor 50 (e.g., an encoder) detects the signal and feeds back and controls the power motor to control the rotation speed of the doctor roller 206. The first sensor 50 is used for sensing the running speed of the adhesive sticker 202 label in real time so as to cooperatively control the rotating speed of the scraper roller 206 driven by the power motor, so that the linear speed of the scraper roller 206 can be matched with (i.e. synchronized with) the running speed of the adhesive sticker 202 label, synchronous control is cooperatively realized, the scraper roller 206 is synchronously operated in real time and accurately tracked, and the scraper roller 206 is synchronously operated in real time and accurately tracked so as to further realize automatic operation.

Preferably, at least one idler roller 301 is floated, either linearly or in a swinging motion, the floating idler roller 301 is provided with a tension control device for providing tension, the respective idler roller 301 is disposed on the floating frame 30 so that the respective idler roller 301 floats, and the tension control device is directly connected to the floating frame 30 to maintain tension on the label waste 205 moving around the idler roller 301. The inert roller 301 is provided with tension, so that the tension can act on the label waste 205 wound on the inert roller 301, the label waste 205 can run in a state of keeping the tension, and the label waste 205 is not easy to break; meanwhile, the floating frame 30 is matched for floating (jogging), so that buffer change can be performed, and the tension is kept stable in a matching manner. When the speeds of the scraper roller 206 and the peeling roller 203 are inconsistent and asynchronous, the running speeds of the scraper roller 206 and the peeling roller 203 are compensated by the inert roller 301 through floating, so that the synchronization is realized; for example, the idler roller 301 will float to compensate when there are accumulated errors inherent in the equipment during continuous production.

It is further preferred that a second sensor detects a position signal of the floating idler roll 301 or the floating frame 30 to which the floating idler roll 301 is attached, and the second sensor (e.g., an encoder or a potentiometer, etc.) detects the position signal and feeds back and controls the power motor to control the rotation speed of the doctor roll 206. The position of the floating frame 30 or the inert roller 301 is sensed in real time by the second sensor, so that the rotating speed of the scraper roller 206 driven by the power motor is controlled in a matched manner, synchronous control is further realized in a matched manner, the scraper roller 206 is enabled to run synchronously in real time and accurately, and the automation degree is higher.

When the number of the inert rollers 301 is more than two, the label waste 205 sequentially winds the inert rollers 301 to run, wherein the third material feeding suspension length of the label waste 205 between the two inert rollers 301 is less than or equal to the hollow length of the self-adhesive label waste 205 with the breakable specification. When more than two inert rollers 301 are used, the hollow parts of the single self-adhesive label waste materials 205 with the breakable specifications can be always dragged and attached in the inert roller mechanism, and the hollow parts of the single self-adhesive label waste materials 205 which are easy to break can not be completely in a suspended state.

In the full-automatic waste discharge device and the full-automatic waste discharge method, the structure is compact, the linear speed of material operation is fed back accurately in real time, for example, the control utilizes the virtual gear ratio principle, and the scraper roller 206 is tracked synchronously accurately in real time. When a slight error occurs in synchronization, the idler roller 301 slightly moves leftwards or rightwards as shown in fig. 5, and the change of the moving value is fed back to the upper computer in real time, and the upper computer instantaneously reduces or increases the rotation speed of the doctor roller 206 in real time. Generally, such very precise, minute amounts of line speed compensation are typically controlled by increasing or decreasing the pulses of the motor power of doctor roll 206, momentarily increasing or decreasing the amount of pulses, to achieve a synchronized control process.

More specifically, using a sensing sensor (e.g., encoder), assume that a doctor roll 206 has a diameter of 100mm, rotates for a pulse amount of 2000psi, corresponds to a pulse angle of 0.18 degrees, and corresponds to an arc length of ≈ 0.016mm. And scraper roller 206 power motor of tracking linear velocity should also rotate arc length 0.016mm correspondingly, supposing that the encoder of power motor is also 2000psi, when diameter 1. When the accumulated errors are increased during continuous production, the displacement errors given by the leftward or rightward movement of the inert roller 301 are fed back to the upper computer from time to time, and the instantaneous pulse of the power motor is compensated by the upper computer to increase or decrease. During production, when the speed is rapidly reduced, accelerated or inching, the speed change is increased, but the acquisition pulse number in a certain time is reflected in the required rotation pulse number of the power motor at any time and is controlled by an upper computer. The compact design and control method not only can realize the continuous and smooth collection of the special-shaped standard wastes without stopping, but also can compensate the rapid change of the speed in the production process through instantaneous and micro-motion pulse number.

The following examples are given in the best mode:

when in use, the self-adhesive 202 material is wound around the peeling roller 203, the label waste 205 and the finished product 204 are separated and peeled off at the peeling roller 203, the label waste 205 is wound around the inert roller 301 of the inert roller mechanism, then the side (namely the adhesive side) with the adhesive of the waste label is attached to the scraper roller 206, and the finished product 204 is continuously produced or wound.

As the label waste 205 passes through the idler roller 301, the idler roller 301 will have an applied tension F, the greater the force applied by the tension F, the greater the tension, and conversely, the less the force applied, the less the tension, generally the tension F being a finely adjustable, controllable force.

When the label waste 205 passes through the scraper roller 206, the scraper 401 on the scraper frame 40 cooperates with the scraper roller 206 to scrape off the label waste 205, and due to the adhesive, the scraped label waste 205 generally forms a regular shape like a folding fan, and naturally falls down to fall onto the receiving table 101 when the scraped waste 207 is accumulated more. The relative positions of the stripping roller 203, the inert roller 301 and the doctor roller 206 can be adjusted correspondingly, and can be set according to requirements.

As described above, referring to fig. 7 and 4, when the label waste 205 of the sticker 202 passes through the peeling roller 203, the idler roller 301, and the doctor roller 206, the label waste 205 has four tangent points a, b, c, and d. As shown, for better describing the invention, it is assumed that the distance between a and b is 20mm, the distance between c and d is 20mm, and the length of the empty space i of the label waste 205 is 50mm (see fig. 4), i.e., neither the spatial distance between a and b nor the spatial distance between c and d has the possibility of completely suspending 50mm empty waste in the air.

As described above, the idler roller 301 is a slightly floatable roller, and the slight floating distance to the left or right is assumed to be 10mm each, so that the floatable space distance between the point of tangency of a and b or the point of tangency of c and d is 10mm to 30mm, and 50mm of empty waste materials are still not suspended in the air, and the risk of waste discharge and breakage is reduced.

Referring to fig. 5, the first sensor 50, such as a high-precision encoder, is a real-time, high-precision, high-resolution encoder-type sensor for sensing the running speed of the adhesive sticker 202 material in real time, and when the adhesive sticker 202 rotates by 1 pulse through the peeling roller 203, the scraper roller 206 is controlled by the upper computer, and should react instantly, and the number of corresponding rotating pulses is calculated according to the principle of virtual gear ratio, so as to achieve the purpose of synchronization.

However, when the continuous production causes an accumulated error inherent in the apparatus itself, the idle roller 301 slightly compensates for the right or left. In general, when the idler roll 301 is to the left, the doctor roll 206 should be produced with a certain amount of pulses reduced, and conversely, when the idler roll 301 is to the right, the doctor roll 206 should be produced with a certain amount of pulses increased. This amount of compensating pulses allows the idler roller 301 to reach a set relative equilibrium position.

As described above, idler roller 301 is a tension roller and also a compensator roller, and generally has a corresponding second sensor for sensing the position of idler roller 301 (e.g., an encoder or potentiometer for sensing the position of the idler roller), and if the position deviates from a desired set position, the amount of motor rotation pulses is reduced or increased.
