Description

DESCRIPTION

THE ATTACHING MEMBERS USED IN CONVEYOR BELTS AND APPLICATION

METHOD

The present invention relates to attaching members used in conveyor belts; in which it is a interconnect component that has rubber (1), metal plate (3), rivet bearing (5) and cord fabric (2) in sequential plates in order to make conveyor belts piece together. The attaching members used in conveyor belts of prior art have been all produced from metal. As it is known, metal materials had a low strength against overextension and elastic resistance. Therefore, producing said attaching members of conveyor belts form metal has been reduced the attachment member resistance and consequently the conveyor belt resistance. In this case, it could be seperated from related attachment member joint of the conveyor belt or cleavage and breakage on metal body could occur during conveyor belt movements especially during drum gear turns caused high tension. Therefore, metal base conveyor belt attachment members could find a field of application only for conveyor belt systems which had a large drum gear diameter. In conveyor belt systems which had a small drum gear diameter, pressure amount per unit area of metal conveyor attachment member has increased and conveyor belt attachment member could be broken easily, since the turning radius occured in the course of conveyor belt movement has been small in proportion to drum gear radius.

Another problem caused by the usage of metal conveyor belt attachment member in present was the friction of metal conveyor attachment member to metal drum gear or to conveyor belt movement elements as roller and as a result of this friction there was damage on both conveyor belt movement systems and conveyor belt attachment members. The damages caused by these frictions have reduced the bench life of both conveyor belt movement elements and conveyor belt attachment member. Again, during the friction of the conveyor belt movement elements for example drum gear, roller and the like and the conveyor belt attachment members made of metal, the sound in the production plant has increased and the working performance of the staff working in production area could become poorer.

l Besides the above-mentioned metal conveyor belt attachment members, rubber conveyor belt attachment members could also be used. Said rubber conveyor belt attachment members could be made by user's skill and manual methods. In this case, the performance of this connection between two conveyor belts was related to the process performance of the staff member. Therefore, attachment members used along conveyor belt could not be mounted with same stability and breakage could happen in weak parts during the movement of conveyor belt; as a result of this production was shut down. The present rubber conveyor belt attachment members were attached by screwing nuts or bolts on rubber body and by the principle of providing the connection of conveyor belt attachment members. The length of nuts or bolts used in attachment process was chosen as rule of thumb by the staff member who would practice the application. Since the decision of nut or bolt length was under the initiative of said staff member, various mistakes could arise during application. The nuts or bolts were screwed on rubber body and the remaining part under said rubber body after screwing was left under conveyor belt. The nuts or bolts one end of which stayed out on conveyor could harm roller and drum gear that were the movement elements of conveyor system during the movement of conveyor belt. Besides, installation could not be completed or the disintegration risk could occur during the movement of conveyor belt when nuts or bolts used for said connection were short.

As well as mounting by manual systems and staff member skill, the present rubber conveyor belt attachment members could increase the production cost since the application period was too much and more workforce was needed.

Since rubber conveyor belt attachment members have not had stable screw application, they were not convenient in order to make a conveyor belt which had stable thickness. Therefore, this has caused pressure and damage in scraper systems. The present rubber conveyor belt attachment member applications were produced from rubber in a single piece. Since only rubber was used as a material in attachment member structure, resistance of the attachment member has decreased. Since any arrangement has not been made in order to facilitate said attachment on smooth rubber body, installation process would extend and also become harder. Description of Figures

4. Rubber centering apparatus

5. Rivet bearing

The present invention namely conveyor belt attachment members have a flexible structure, since they are made of flexible materials for example rubber and the like. By this way, it minimizes the severances and breakages occured in metal attachment members continuously. Since the installation of conveyor attachment members according to present invention is performed with erecting equipment but not with manual systems, the defects occured in manual installation can be prevented. Again, production cost is minimized through usage of erecting equipment. The present invention prevents the friction of conveyor belt comprises rubber outer coating with conveyor belt movement elements and as a result of this friction prevents drum gear and roller which are conveyor belt system movement elements from damaging. Besides these, the situation of not only being produced from rubber increases the resistance of said attachment member. Also, the comfort of voice-reduced production field during production is increased by removing metal-to-metal friction.

Since conveyor attachment members according to present invention comprise various resistance enhancer materials and installation facilitator materials in rubber outer coating, both the installation of conveyor belt systems is facilitated and the resistance of attachment members is maximized. Metal plates (3) disposed in rubber (1) is supported both rivet system and cord fabric (2) so that the resistance of belt joint is increased. Thus, the thickness of conveyor belt which will be attached is protected and working performance coupled with belt strippers can be provided.

The present invention relates to attachment members used in conveyor belts; in which they include at least two cord fabric (2) plates positioned as various plates in outer coating, metal plates (3) on which settled rivet bearings (5) (nail channels) facilitating rivet installation are provided, at least one rubber centering apparatus (4) facilitating the installation of conveyor belt attachment member and rivet bearing (5) which is a channel extending from the top side to the bottom side of conveyor attachment member and also is designed in proper shape and dimension that the rivet used for installation can pass into it.

Since the external structure of conveyor attachment members according to present invention is covered with rubber (1), it has high resistance to heat, chemicals, oil and abrasion. In case of applications with different purposes, above-mentioned rubber (1) plate can be replaced. If appropriate, rubber (1) polyurethane can be used instead of rubber (1) plate or rubber (1) can be covered with teflon. There are at least two cord fabric (2) plates at inner side of said rubber (1) structure. In said body, the cord fabric (2) is positioned as at least two lines under metal plates (3). Said cord fabric (2) is a flexible material made of high quality polyester and nylon. The weaving quality of cord fabric (2) (warp and weft resistance) can be arranged depending upon applied conveyor belt. In applications required high elasticity resistance (in conveyor belt applications used with lower drum gear diameter), the quality of attachment member is increased by enhancing cord fabric (2) quality. Metal plates (3) are positioned on the top side of cord fabric (2) disposed as two lines. Metal plates (3) include settled nail slots in other words rivet bearings (5) in its structure. Said rivet bearings (5) is positioned consecutively on metal plates (3) preferably as it constitutes 7 neat holes. Each hole group comprising preferably 7 nail holes is positioned consecutively and equidistantly on metal plate. Each nail hole positioned on metal plate (3) constitutes a rivet bearing (5). Said rivet bearings (5) reset for rivets in compatible with their physical dimensions and shapes.

On the main body of conveyor belt attachment members according to present invention, at least one rubber centering apparatus (4) is positioned as the main body of said rubber (1) is present at focal point. Thus, the centering process for attachment members can be performed easily during installation.

The conveyor belt attachment members according to present invention provides the attachment of conveyor belts by rivets positioned on above-mentioned rivet bearings (5). A suitable area is formed by primarily stripping the upper parts of required conveyor belts with a stripping apparatus. Said stripping apparatus is a blade mechanism which can be adjusted preferably on specific dimensions for cutting process. The attached parts of each conveyor belt after this process should be thinned properly. The prepared conveyor belt is combined with an installation apparatus. Said conveyor belts equipped with installation apparatus are fastened with a rivet from convenient points impeccably and homogeneously by aligning through rubber centering apparatus (4). Conveyor attachment members are aligned with installation apparatus on both sides of conveyor belts that will be attached. After the aligning process, rivets are driven by means of rivet drivers optionally running manually or automatically on installation apparatus. After the riveting process, a part of rivet is projected from bottom side of installation apparatus by digging into two conveyor belts. By planning this excessive rivet projected from bottom side of installation apparatus, a flat surface is formed under conveyor belt attachment part.
