Description

Stripper for stripping a breaker ply from a storage tyre component and storage box comprising same

Technical Field

The utility model relates to a stripper that is used for following storage tire part, for example side wall tape strip, peels off the spacer fabric layer when rolling up from the storage material. The utility model discloses still relate to including stripper's storage box.

Background

Known strippers include a plurality of rollers for guiding the stock tire components and the breaker ply layer from the stock roll along a stock path and a breaker ply path, respectively. The stock path and the cloth liner path are separated at a separation position. At a downstream location at the separation location, a magazine path is connected to a release station, which guides the magazine tire components further to a tire component server or tire component production device. The end point of the cloth liner path is a cloth liner roll, which collects the separated cloth liner.

SUMMERY OF THE UTILITY MODEL

A disadvantage of the known stripper is that the magazine tyre components are not always separable from the laying cloth layer, and there is a tendency for the laid cloth layer to be pulled together downstream of the separation position from the magazine path towards the laying cloth path. If this is not found in time, the magazine tyre components will be wound onto the blanket roll together with the blanket layer, so that the discharge or feed to the release station will be interrupted.

An object of the utility model is to provide a stripper and contain stripper's storage box, wherein floorcloth layer can separate more reliably with storage tire part.

According to a first aspect, the present invention provides a stripper for stripping a backing layer from a stock tyre component when the stock tyre component is unwound from a stock roll, wherein the stripper comprises a plurality of rollers for guiding the stock tyre component and the backing layer from the stock roll along a stock path and a backing path, respectively, wherein the plurality of rollers comprise a separation roller located downstream of a separation position, wherein the backing path is permanently separated from the stock path at the separation position, the stripper further comprising a drive element coupled to the separation roller for rotating the separation roller faster than the other rollers of the plurality of rollers.

By the rotation speed of the separation roller being faster than the other rollers of the plurality of rollers, a speed difference between the stock tire component and the laying cloth layer at the separation position can be created. The speed difference can effectively separate the material storage tire components from the cloth liner layer, so that the material storage tire components are ensured to continue on the material storage path, and meanwhile, the cloth liner layer returns to the cloth liner material coil through the cloth liner path.

Preferably, the plurality of rollers includes a driving roller, the driving element is the driving roller, and the stripper includes a transmission element for transmitting the rotation of the driving roller to the separation roller at a transmission ratio corresponding to more than one rotation of the separation roller per one rotation of the driving roller. By using one of the other rollers as the drive element, there is no need to provide a special or additional drive element. In particular, the other rollers rotate or are driven to rotate as a result of the layers of matting and/or stock tire components passing thereover. Furthermore, since the other rollers automatically rotate as the breaker ply and/or stock tire component is pulled through the stripper, there is no need to provide a control unit or similar component to control the speed of rotation of the other rollers. Thus, the pulling of the breaker ply and/or stock tire component through the stripper causes the separation roller to be rotated by the one other roller.

In one embodiment, the transmission element is a transmission belt. The drive belt is an efficient way of transferring rotation from one rotating object to another.

In one embodiment, the belt is arranged to surround the drive roll at a first diameter and surround the separation roll at a second diameter, wherein the first diameter is larger than the second diameter. Thus, one revolution of the drive roll corresponds to more than one revolution of the separator roll, thereby creating a transmission ratio.

In a further embodiment, the drive roller and the separation roller each have a roller body with a third diameter that is the same for the drive roller and the separation roller, wherein the drive roller comprises a pulley extending with the first diameter to match the drive belt. The above-mentioned transmission ratio can be obtained by locally increasing the diameter of the drive roll at the pulley.

In a preferred embodiment, the third diameter is equal to the second diameter. The conveyor belt can thus engage the separating roller with the same diameter as the roller body.

In an alternative embodiment, the drive roller and the separation roller each have a roller body with a third diameter that is the same for the drive roller and the separation roller, wherein the one other roller comprises a pulley extending at the second diameter to match the drive belt. The above-mentioned transmission ratio can be obtained by locally reducing the diameter of the separating roller at the pulley.

Preferably, the third diameter is equal to the first diameter. The conveyor belt may thus engage the drive roller with the same diameter as the roller body.

In another embodiment, the drive roll is the last roll that guides the scrim layer along the scrim path at the separation location. The drive roll may thus be driven by a cloth liner passing along said drive roll. Thus, the peripheral speed of the drive roll may be equal to the conveying speed of the scrim layer.

In another embodiment, the separation roller is the first roller defining the stock path immediately downstream of the separation location. In other words, the separating roller is the first of the plurality of rollers to guide only the magazine tire component along the magazine path, independently of the breaker ply. Thus, the separation roller is arranged to directly contact the magazine tyre component, e.g. without a breaker ply in between. The separating roller can thus effectively accelerate the speed of the magazine tyre component independently of the layer of matting and thus create a speed difference between the magazine tyre component and the layer of matting.

In another embodiment the drive roll and the separator roll form a pair of rolls, wherein the laying cloth path passes through the middle of the pair of rolls and the stock path passes through the same side of the pair of rolls. The cloth laying path and the stock path can thus be effectively separated at the roller pair.

In a further alternative embodiment, the transmission element comprises a gear chain having at least two meshing gears. A gear chain may provide an effective alternative to the drive belt discussed above. The above-mentioned gear ratios can also be achieved by selecting appropriate gear ratios.

In another embodiment, the plurality of rollers further comprises a set of peel rollers for peeling the layer of dunnage from the stock tire component at a peeling location upstream of the separation location, wherein the layer of dunnage is rejoined with the stock tire component between the peeling location and the separation location. The stripping roller set may be released well from the blanket layer or substantially disengaged from the magazine tire component, in advance of or in preparation for the actual separation of the magazine tire component from the blanket layer at the separation location.

In another embodiment, the drive roller and the separation roller are parallel to each other. Thus, the transmission element can convey the rotation between the drive roller and the separation roller in a single plane perpendicular to the roller axis.

According to a second aspect, the present invention provides a storage case, comprising a stripper according to the first aspect of the present invention. The magazine may be inserted or housed in a release station for a tire component server or tire component production device. A stripper may be provided on the magazine to supply magazine tyre components to the release station and collect the cloth liner onto the cloth liner roll.

The various aspects and features described and illustrated in this specification may be applied separately or randomly. These various aspects, in particular the aspects and features described in the appended dependent claims, may be carried out by divisional patent applications.

Detailed Description

Fig. 1 illustrates a magazine carrier or magazine 300 for insertion into a discharge station (not shown) of a tire component manufacturing apparatus (not shown).

The stock carrier cart 300 includes a stock roll F and a blanket roll G. The stock material roll F is wound with a plurality of turns of a strip-shaped stock tire component a, such as a sidewall or a run-flat reinforcing tape. Each winding is spaced by a scrim layer B to prevent each layer from adhering to each other. The stock roll F and the laying cloth roll G cooperate in a known manner to unwind the stock tyre components a from the stock roll F while simultaneously collecting the laying cloth layer B on the laying cloth roll G. Typically, the blanket roll G is actively driven to pull the blanket layer B and wind it onto the blanket roll G.

The magazine carrier 300 includes a separating device or stripper 1 for stripping and eventually separating the breaker ply B from the magazine tyre component a when said magazine component a is unwound from the magazine reel F. In particular, the stripper 1 is located at a position between the stock roll F and the blanket roll G. Once the layer B of laying cloth is separated from the stock tire component a, the separated layer B of laying cloth is returned and collected or wound onto a roll G of laying cloth, while the separated stock tire component a is discharged from the stock carrier cart 300 in the discharge direction Z to a discharge station (not shown). The payout station may be provided with adjustment rollers to control the speed at which the stock tire component a enters the payout station.

As shown in fig. 1 and 2, the peeler 1 includes a plurality of rollers R1-R6 for guiding the magazine tire component a and the laying cloth layer B from the magazine roll F along the magazine path S and the laying cloth path L, respectively. Preferably, the rollers R1-R6 are rotatable about mutually parallel rollers X1-X6, respectively.

The plurality of rollers R1-R6 includes a set of peel rollers R1-R3 for peeling the backing layer B from the stock tire component a at the peeling position P. Thus, the breaker ply B is peeled off from the magazine tire component a and then re-bonded to the magazine tire component a. The above-mentioned peeling is ready for the subsequent separation of the blanket layer B on the peeler 1.

More specifically, the peeling roller groups R1-R3 include a first peeling roller R1, a second peeling roller R2, and a third peeling roller R3, which collectively form a loop on the blanket path L. When the magazine 300 is set, the operator manually guides the scrim layer B through the loop, and the magazine tire component a is guided directly from the first peeling roller R1 to the third peeling roller R3. The breaker layer B was separated from the magazine tire component a at the first stripping roller R1 and then rejoined with the magazine tire component a at the third stripping roller R3.

The plurality of rollers R1-R6 includes a drive roller R4 and a separator roller R5 for permanently separating the stock tire component a from the blanket layer B. Specifically, the drive roller R4 is located at a separation position Q, downstream of the peeling position P where the stock path S is permanently separated from the blanket path L, and the separation roller R5 is located at a position downstream or immediately downstream of the separation position Q. More specifically, the drive roller R4 is the last roller that guides the scrim layer B along the scrim path L at the separation position Q. In other words, the drive roller R4 defines both the laying cloth path L and the magazine path S, and supports or guides the laying cloth B and the magazine tire component a. In contrast, the separation roller R5 first defines the stock path S immediately downstream of the separation position Q. More specifically, the separation roller R5 defines the stock path S separately or independently from the cloth liner path L. In other words, the separation roller R5 defines only the magazine path S, and supports or guides only the magazine tire component a.

Thus, the drive roller R4 and the separation roller R5 constitute a roller pair R4, R5 in which the blanket path L passes through the middle of the roller pair R4, R5, and the magazine path S passes along the same side of the roller pair R4, R5, thereby effectively separating the magazine tire component a from the blanket layer B.

The plurality of rollers R1-R6 also includes a return roller R6 for returning the blanket layer B to the blanket roll G. Specifically, the blanket layer B is separated from the magazine tire component a at the drive roller R4 and then directed directly to the return roller R6, away from the magazine path S.

The driving roller R4, as a driving element, is coupled or connected to the separating roller R5 such that the separating roller R5 rotates at a faster speed than the other rollers R1-R4, R6 of the plurality of rollers R1-R6. As a result, the separating roller R5 can pull the magazine tire component a faster than the drive wheel R4 guides the laying cloth layer B, thereby creating or creating a speed difference between the magazine tire component a and the laying cloth layer B at the separating position Q. When the cloth layer B is actively pulled toward the cloth roll G in fig. 1, the friction between the cloth layer B and the drive roll R4 causes the automatic rotation of the drive roll R4. Accordingly, the peripheral speed of the drive roll R4 is equal or substantially equal to the speed at which the scrim layer B is drawn toward the web G.

In order to achieve the connection of the drive roller R4 with the separation roller R5, the stripper 1 comprises a transmission element 4. The transmission member 4 is provided to transmit the rotation of the drive roller R4 to the separation roller R5. In the present embodiment, the transmission element 4 is a wire or a transmission belt 40. As shown in fig. 2, the drive belt 40 is disposed around the drive wheel R4 at a first diameter D1 and around the separator roller R5 at a second diameter D2, wherein the first diameter D1 is greater than the second diameter D2. Thus, each revolution of drive roller R4 produces more than one revolution of separator roller R5, thereby producing a gear ratio. The transmission ratio between drive roll R4 and separator roll R5 may be, for example, 1:1.1, meaning that for every revolution of drive roll R4, separator roll R5 rotates 1.1 (one and one tenth) revolutions.

It should be noted in this embodiment that the drive roller R4 and the separation roller R5 each have a roller body 2 having a third diameter D3. Specifically, the roller body 2 has a circumferential main surface, an outer circumferential surface or guide surface 20 extending at a third diameter D3 for guiding the magazine tire component a and/or the laying cloth layer B. The third diameter D3 of drive roll R4 and separator roll R5 is the same. In other words, the guide surface 20 of the drive roller R4 and the separation roller R5 have the same diameter.

In order to provide the first diameter D1 and the second diameter D2 for the drive roll R4 and the separation roll R5, respectively, the diameter of the drive roll R4 may be locally increased or enlarged and/or the diameter of the separation roll R5 may be locally decreased or reduced. In this embodiment, the drive roller R4 is provided with a pulley 3 extending at a first diameter D1 for mating with the drive belt 40. The pulley 3 is mounted around the roller body 2 of the drive roller R4, for example, in a circular ring shape, or it may be attached to or extend from the roller body 2 on the drive roller R4 side in the axial direction. The pulley 3 may be provided with grooves or ridges to more securely receive and/or accommodate the drive belt 40.

In the embodiment shown in fig. 2, the transmission belt 40 extends or is disposed around the roller body 2 of the separation roller R5. Thus, in this example, the second diameter D2 is equal to the third diameter D3. Alternatively, another pulley (not shown) may be provided on the separation roller R5 to receive the drive belt 40 at the second diameter D2. In this example, the second diameter D2 may be larger than the third diameter D3 as long as it is smaller than the first diameter D1. Alternatively, the separation roller R5 may be provided with grooves or recesses (not shown) to receive the drive belt 40 within the third diameter D3. Thus, the second diameter D2 may also be smaller than the third diameter D3, thereby further increasing the gear ratio described above.

Fig. 3 shows an alternative stripper 101 according to a second embodiment of the invention, which differs from the previously discussed stripper 1 in that it is provided with or comprises a pulley 103 on the separation roller R5, instead of the drive roller R4, extending with a second diameter D2 for matching the drive wheel 40. The pulley 103 is smaller than the guide surface 20 of the separating roller R5 extending with the third diameter D3 and can therefore be recessed with respect to said guide surface 20. The pulley 103 may also be an integral part of the separation roller R5, such as a part of the neck, or as an extension of one axial side of the separation roller R5.

The drive belt 40 may be adapted to be disposed about the drive roller R4 at a third diameter D3, in this case, the third diameter D3 is equal to the first diameter D1. Alternatively, the pulley 3 shown in fig. 2 may be applied to the drive roller R4 to further increase the transmission ratio as described above.

Fig. 4 shows another alternative stripper 201 according to a third embodiment of the invention, which differs from the previously discussed strippers 1, 101 in that the transmission element 204 comprises or is formed by a gear chain 240. The gear chain 240 includes at least two meshing gears 241,242, such as a first gear 241 connected to the drive roller R4 and a smaller second gear 242 connected to the separator roller R5. Thus, a similar transmission ratio can be produced. More gears (not shown) may be added to further increase the transmission ratio.

Other mechanical means for driving rotation from the drive roll R4 to the separation roll R5, such as a toothed belt or chain, are clearly known or conceivable to those skilled in the art, as long as the same or similar technical effect is achieved.

It is also clear to the skilled person that any other roller R1-R3, R6 of the plurality of rollers R1-R6 may be used as a driving element, as long as the selected roller can be automatically rotated at a desired speed by the passing clothing sheet B, thereby creating a transmission ratio at which the separation roller R5 rotates at a faster speed than the other rollers R1-R4, R6 around it.

It is to be understood that the above description is intended to illustrate the operation of the preferred embodiments and is not intended to limit the scope of the invention. Many variations, modifications, or combinations that are apparent to those skilled in the art based on the above discussion are intended to be included within the scope of the present invention.
