Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a pulley coating, i.e., rounding on the circumferential surface of a belt pulley, a processing roll, etc., which improves belt pulling force, eliminates slippage, increases belt life, and promotes belt alignment. This concerns common precautions for elastomeric tread products. The M product is equally applicable to many types of rolls used in industry, such as conveyor belt idler seals and pressurizing rolls or drive rolls.

Rubber coatings are most commonly used in steel, steel 7 1J-, roll II
Rubber companies that have special equipment for this purpose (thus, apply it to the rubber company).When the coating wears out, the rubber is removed from the equipment and replaced in 07'tJ6'1.
”-The 0 sent to the covering m facility is usually 1 ;1゜,
This requires a temporary shutdown of the user's production line, which is otherwise costly and time consuming.

Several years ago, the applicant developed a system for attaching a coating to a pulley, which has the advantage of being used in such areas as desired by the user. It is necessary to supply it to the end user through this site. This unit is mounted on a roll of the indicated diameter, for example, on the circumference of a four-wheel
X@ has the curvature it takes to connect. A related construction is shown in U.S. Pat. No. 3,354,734S, in which the backing plate is designed to be assembled into guide and retaining members that are welded or otherwise fastened to the Gooley surface. This particular structure has the advantage of being applied and regenerated as required by the kneader. A somewhat similar technique for using the resulting curvature sheath bolted to the face of a 1-Lee is shown in US Pat.

One of the drawbacks of the coating products available to date is that moisture, sand, and other abrasive particles act on their own under the metal plate, corroding and wearing away the metal plate support for the product. .

In the case of U.S. Patent No. 3,354,735, the retainer) IJ is melted in one rotation! I! As such, it is naturally fixed, thus reducing flexibility in the positioning of the covering on the sill 1 and almost inevitably resulting in unbalanced deflection. Also, some relative motion is inherent between the sheathing and the retaining strip, which wears down the roll circumference, resulting in component wear and premature failure.

Attempts have been made to round off tires to obtain fully a-endless tires that tend to be driven around two wheels of corresponding diameter. Jin's technology requires the manufacture of cars with special dimensions and diameters. The override of such requirements is U.S. Pat. No. 1,636,492, 1

Kl because the fabric reinforcement belt is covered in the 9th one that is used for a limited time! The used 9@*ml ec is to cut the belt into a relatively narrow strip of width #lc, and the strip/fi is then cut into a spiral shape by K1N adhesive on the 1-G.
The belt strips are tied together, covered with 10 strips, tapered at various points, and fastened at opposite ends of the belt strips. This type of sheathing is susceptible to stretching and premature failure, and its action is essentially in a single direction, in the direction of tension of the belt strip on the v-ru. Furthermore, there are disadvantages in working with the cements and adhesives required and universally used for the attachment of belt strips. ! Installation of Ik adhesive is costly and sandy, and it is difficult to handle 4IK over a wide temperature range and 111IK of moisture.

The 61S material of the present invention comprises an inner sheet of flexible, non-stretchable material, a relatively thick layer of elastomeric coating material on the usually outer side of the sheet, and a layer of elastomeric rubbery material on the usually lower side of the sheet. It is a laminated, integrally lined structure consisting of a relatively thin coating or electrolyte. The laminate sandwich structure is flexible and easily slips onto the outer surface of a pulley or roll.

I jump to myself. The circumferentially spaced nine ends of the #1 cover S# are tightened to the circumference of the outermost ring 1, and the rubber-like coating of the coating member is frictionally engaged with the outer circumference of the fourth ring. This rubber under m;
- Prevents slippage and movement between the covering member and the roll, prevents corrosion and abrasion, provides tight protection against moisture and foreign matter that enters the interface between the 1-lead and the rolled member, and prevents irregularities in the covering member. - Modifies contact with the roll surface, facilitates contouring to the curvature of the product'iO-ru, and prevents twisting or sharpening of the inner non-extensible sheet. The performance of the intermediate sheet is to form a non-stretch or 'yield' laminate, to prevent distortion or movement of the assemblies during rotation, such as the ridge 1 in front of the point of load application, and to prevent 1 of the covering member 1. - Conclusion to Lee - To support collaboratively. Third outer layer (ksly)
or lay@r) is designed to contact the workpiece, and there are many designs such as pulley coating, 1 [material feeding, rice milling], food processing (f o odproc), etc.
essing), etc.

It is an object of the present invention to provide flat surfaces without the need for pre-contouring.
It can be reliably rolled out in the desired condition, and can be easily cut into lengths to fit into one piece or roll of various straight throughs and lengths by the gourd. Tons can be cut in the heat, and at the user's location in the field with ordinary worksite equipment and with ordinary techniques.
It is intended to provide a coating product that can be easily and quickly installed. As a result, the user needs to use all the pulleys and handles on a daily basis! - It is necessary to store only one size of sheathing for sheathing to be attached to pulleys, etc., and thus pre-formed sheets of various sizes and shapes can be used to fit different size pulleys or rolls. The need to keep covering members on hand is eliminated.

Another object of the invention is to provide a flexible post-installation product and method of attachment that allows selection of coverage to the required circumferential area of a pulley or roll.

Another object of the invention is to obtain rapid and effective installation as well as cooling and shrinkage of the intermediate bonded sheet to t-1! In fact, it ensures that the rubber undercoating adheres to a sealed fit grip-like layer.
! The purpose of having a covering member on one surface of the aK yori reference 1-ri is to provide fortification in an elegant and effective manner.

The invention has other objects and advantages, some of which are illustrated in the drawings and which form part of this specification and will now be described with reference to preferred forms of the invention. However, nine variations shown in the figures and in the description can be adopted and implemented within the scope of the invention according to the claims.

The covering member 6 of the present invention is designed to be attached to a peripheral wall 7 of a belt pulley, a process roll, etc., and can be easily attached to a thin, flexible, non-stretchable sheet 9; A layer of flexible covering material 12 which is adhered to the outer surface of the sheet and typically H! The elastomeric layer 13 supports the outer circumferential surface under torsional stress and is bonded to the outer circumferential surface (ms+t).
lng) It includes means 28 for attaching a covering member t-m1i to the outer periphery (1ii16) of the wall 7 by cutting out the outer MIIK* so as to occupy the circumferential surface of the wall 7.

According to the invention, and as a basic gist of the invention, the covering member 6#i is most conveniently and economically cast in a flat, integrally bonded and laminated form with rubber grafts, the form a It can be supplied to industrial users so that the covering member can be cut to a size to be wrapped and fastened around the outer surface of a belt pulley, 10 ce/grol, etc.

In its preferred form, the internally extensible sheet 9 comprises an axial violet sheet metal that is flexible enough to be wrapped snugly around the circumferential wall of the pulley, yet sufficiently flexible. It can give a certain amount of tension.

Sheet steel up to a thickness of approx. 611 m has been found to be satisfactory for a wide range of applications in which the product has been tested. The laminated carcass has a relatively thick layer of covering material, essentially an elastomeric tread-like material, attached to the outer side of the sheet 11, usually the outer side of the sheet 11, and a relatively thick layer of covering material, usually an elastomeric tread-like material, attached to the outer side of the sheet 11. and a relatively thin coating or laminate of elastomeric material 13 that is adhered. The entire product is thus completely flexible and can be marked on the circular periphery of the pulley or roll.

The lightweight metal insert supports the fastening means and the shear stresses that the product experiences and creates dimensional security, while the elastomeric undercoating 13 forms a torsion glyph and dampens the loads on the fastening means. , I! of a pulley or a link as a fastening means! 7 and 9 motion friction-engaging rubber undercoating retains gold 1! Just ask.

As a basic form of the present invention, the to-be-machine member surrounds the to-be-followed member @
By simply fastening the nine ends 17 and 18 spaced apart in the circumferential direction of the covering member, it can be easily used for a circular shape or a shape. can. Any convenient type of fastening can be used, such as bolting or crotch-nailing or riveting or welding to the ends such as threads; - by fixing it around the wall of the
;, it is noteworthy to do. The elastomeric underbooting 13 forms the threaded p-glyph 1 and cooperates with the clasp &2B to carry the load.

One of the nine features of the present invention is that the forces experienced by the sheathing member in use, such as during the drive of a conveyor belt or the like, are initially shear forces and that the sheathing supported by the wall The pressure created by the belt on the member is to maintain the covering member in 1-Sea IIK pressure contact. Resistance to shear is determined by the non-extensible member 9 and the inner and outer laminae 12 bonded thereto. ) It has been found that it can be easily obtained by combining with 3. As mentioned above, different elastomeric materials can be used for the two laminae 12 and 13; it is only required that the elastomeric material be adhered to the inner reinforcing sheet 9. is about 5 for most purposes
Elastomeric materials having a hardness of 0 to 60 Shore men can be used as the thin layer.

Member 9 is provided with sufficient tension, but 1 - 1 wall circumference! ! It is preferably formed of approximately 16-28 gauge sheet metal so that it is flexible enough to be wrapped snugly around this wall.

Other non-metallic materials may be used to provide the requisite non-stretch strength, adhesion to elastomeric products, and flexibility for wrapping around belt pulleys or four-wheels. Be yourself. For such use rounding, fiberglass reinforced phenolic epoxy resins, polycarbonates, polyester resins, urea resins and 7 omaldehydes, AB8 (acrylic v1 ethryl butadiene/styrene) and Krealst
lc) (TM) 6 members 9 (suggested to be non-stretchable plastics) are arranged in the body of the elastomeric article to form a relatively thin bottom 13) structure extending from the central plane. The elastomeric materials making up layers 0, 1, and 13 can be the same, or they can be easily selected to obtain the best properties for each individual use. Preferably the rubber material of the bottom 13 is 1-
Seawax 7 and OII are adapted to obtain a high coefficient of friction when in contact and at the same time with a minimum of imperfections to prevent movement 11 of the coated product during operation. ik
It protects metal inserts from corrosion and abrasion, making them especially useful in food processing operations! ! It is relatively soft to prevent material from getting between the covering member and the first lea, which is a protective material. At the same time, a nine-bottom rubber layer 13 permanently bonded to the back m of the metal sheet helps prevent kinking and wrinkling of the metal when bending to fit small diameter one-sheet surfaces. It has been found that this thin rubber backing, in combination with a non-stretchable sheet, reliably stops the coated product from slipping on the pulley or roll wall unless used in close contact with the pulley or roll wall to create further compression. .

In the form of the invention shown in FIGS. 81 to 4, the covering member has a length of strip extending in the circumferential direction of the pulley wall 7, and as shown in FIG. d
It is generally arranged so that a large number of Nostrits 1 are lined up horizontally along the line (imens ion), and a large amount of information is obtained. The coated strips 1 are conveniently made with a relatively narrow width of 5 to 10,000 meters and a convenient production length of 300 to 1,000 meters or more. The thus sized FE preparation is conveniently supplied to the knees in flat elongated form or in the form of a coil. 3. The laser then cuts from the supplied long material a piece having a length corresponding to the circumference of the roll to be coated.

1- When installing the covering product on the sea, it is good to have experience with rubber lining, so it is tight! When pressure is applied to the rounding sheath, the rubber backing acts to prevent movement and maintains the dragon/bully in its initial position.

To obtain 100% contact between the coating and the 1-sea surface,
Some IQIJ of the position of the covering member on the 1st column is very much needed, if not required. The deviation of the length of the covering member from the cross section orthogonal to the axis of 1-9- results in a gap at one edge of the covering member due to the contact of the covering member with the pulley at a radius of 9. On one side of the component product T1, there is a K111 screw that facilitates proper and accurate installation, and a K111 section that allows the positioning of the coating to be precisely matched to the contact surface.
Add 11th floor agent.

Preferably, water with a wetting agent, such as a 1s thialcohol solution, is also sufficient.As a feature of the present invention, the bottom layer 13 is formed with a plurality of longitudinally spaced, laterally extending grooves 6, Grooves are added to the pulley wall and the back 11IIK of the sheathing member and spaced longitudinally t, with an I/c open passage between them for the drainage of the lubricant exuded from the land 17 when the sheathing member is fastened to the wall of the product. A land 17 is formed which engages the pulley IIK and extends laterally.

In the configuration of the present invention shown in FIGS. 1-4, the laser cuts the length of the coating member according to the circumference of the pulley wall to be coated. The volatile liquid lubricant is then applied to the pulley wall or
The strip is applied to the back side of the member, and the strip is placed around the sheath wall in its precise position I/cv4- such that its ends 21 and 22 are oriented in an oriented relationship as shown in FIG. Preferably, banding means 3 (FIG. 5) are utilized on the strip to compress it against the 1-Lee wall in the local direction □' to obtain 100 mm face-to-face contact. This operation squeezes excess lubricant into the grooves 16. The standard band shaft fixing tool is Band-It (Band-It).

An aqueous neoprene solution sold by Oporation is a suitable material for this use. Latex-based paint is hard and fully tack-free.
The up-filled pulley seals the surface against rust and corrosion and cooperates with a rubber backing to securely hold the coating in place.

As a feature of the present invention, the strip width of the coated foreign material is limited to a manageable width for accurate installation of the pulley@I/C and full intimate contact with the pulley wall by the clamp 71 member 23. At the same time, the relatively narrow width of the coating strip allows for easy placement of a plurality of longitudinally transverse strips 1-I)- as seen in FIG. The user can thus easily select the amount of pulley surface to be coated. In many cases,
1 - It is only necessary to cover the surface αI~70. The circumferential groove around the completed pulley 4) will thus absorb the water carried by the belt placed around the sheathing,
A groove is easily formed to remove mud and other things, and one or more of such grooves can be used as a guide groove for a belt, etc.

Fixing the covering strip here means both 11!1 and 221-Lee-11K or 51i! of the covering strip. .

A modified form of the present invention is shown in Figure 8, where the product consists of a wide sheet 31 of collapsible elastomeric material, a relatively thick outer sheath 12a and a relatively thin protective and wall grip underside. The coatings 13 (1) are coplanar and parallel to the central plane of the sheet 31, laterally spaced apart and vertically contiguous (conterminous),
It consists of a plurality of flat IA and thin malleable metal or other non-extensible members 9α which are integrally bonded thereto. The latter is formed of a plurality of longitudinally spaced and transversely extending blocks for the release of the lubricant or adhesive as shown in the 1sl embodiment, but the use of lubricant is not a feature of the present invention. Although this shape is not considered limiting, an important feature of this design is that the sheet can be cut into a volume J6 between members 9a to form a plurality of elastomeric strips similar to the strips 78 described above. To], the strips are designed to keep the lugs side by side in a number of strips along the length of the pulley wall, and the strips are designed to keep the lugs side by side along the circumferential direction of the pulley wall as described above. Once the length of the strip extending is wrapped around the 1-CIIIVC and secured, the strip can be cut transversely to the desired length. The product is made into large sheets using a molding press as shown in Figure 8. The lateral spacing between the reinforcing members 9α allows easy slicing of the elastomeric material between said members to form strips of predetermined length. Thick elastomer on the outside to facilitate slicing the sheet into individual strips! g F1 member 91! The slits can be formed with a plurality of longitudinally extending slits that are parallel to each other and spaced apart from each other to facilitate and accurately cut the elastomeric material.
