Description

The utility model relates to equipment for the production of composite reinforcement containing a spiral winding, in particular to a tool facilitating the process of threading the roving of the coils of the block forming the periodic profile of the composite reinforcement.

According to the patent RU 76659, a technological line for the manufacture of composite reinforcement is known, including a matrix that forms a flat ribbon from roving threads and converts a flat ribbon of rovings into a cylindrical shape, the first spiral winding unit in which a single rod is formed, the second spiral winding unit in which secondary winding is performed a bundle, while both blocks of the spiral winding work simultaneously.

The disadvantage of the known device is the low productivity of the equipment associated with interruptions in operation caused by the need for frequent replacement of coils in the nodes of the spiral winding.

The closest to the claimed technical solution is the device for the spiral winding of a technological line for the production of composite reinforcement, known from the description of the patent RU 2636061, containing a frame, located in series two spiral winding units, each of which consists of a pipe fixed in bearings and driven in rotary motion through a mechanical transmission from an electric motor, a coil mounted on bearings with the possibility of rotation relative to the pipe, while each coil is made with the possibility of rigid engagement with the pipe and disengaging with the main pipe, while during the period when the coil is disengaged with the pipe, it is provided free rotation relative to the pipe and the supply of the bundle winding to the above coil, while both spiral winding units work alternately, in the first unit the operating mode changes and the thread is wound onto the flow of the reinforcement support rod, and in the second unit the cat is refilled ears with a thread from the threading device.

The disadvantage of the known device is the inconvenience in operation due to the absence of a device for moving the filling package for alternately filling the coils, as a result of which it becomes necessary to use a separate filling device for filling each coil.

The technical result of the claimed utility model is to improve the usability of the unit for forming a periodic profile of composite reinforcement in the process of threading the coils with twisted thread for spiral winding of the reinforcement rod directly during the operation of the unit for forming the periodic profile of composite reinforcement, eliminating the need to duplicate the unit for threading the coils with thread for each individual coil ...

The technical result is achieved by the fact that the device for threading the roving of coaxial coils of the block forming the periodic profile of the composite reinforcement, according to the utility model, is made in the form of a platform with a rotating device installed on it with an electric drive, made with the possibility of vertical placement of the roving bobbin on it, while the platform made with the ability to move along horizontal guides located in the lower part of the frame of the unit for forming a periodic profile of the composite reinforcement along its longitudinal axis.

Implementation of the device for threading the roving of coaxial coils of the block forming the periodic profile of the composite reinforcement in the form of a movable platform, with a unit for placing the filling reel located on it, allows you to move the filling reel of roving of a standard format (height 260 mm; diameter 185 mm; weight 9-15 kg , with unwinding along the inner diameter) along the guides for the bobbin that needs threading, thereby eliminating the need to use a separate threading device for threading each bobbin, i.e. the need to duplicate the filling unit. At the same time, a rotating device placed on the platform, driven by its own electric drive, makes it possible to twist the roving threads directly in the process of rewinding it onto spools.

Thus, the claimed utility model allows creating a unit for threading the roving thread that is convenient for use directly in the process of operation of the unit for forming a periodic profile and an easy-to-use unit for threading the bobbins.

The essence of the claimed utility model is illustrated by figures:

FIG. 1 shows a general view of the block for forming a periodic profile of a composite reinforcement.

FIG. 2 shows a general view of the platform for moving the roving filler reel.

The block for forming a periodic profile of composite reinforcement contains a frame 1, coils 2 with drives 3, devices 4 for spiral winding of the supporting rod of the reinforcement, a device for threading roving of coaxial coils 2 of the block for forming a periodic profile of composite reinforcement is a platform 6 made with the ability to move along horizontal guides 5 with a rotating device 8, equipped with its own electric drive 7, a roving bobbin 9 is vertically placed on the rotating device 8. Units of the same type are designated in the drawings with the same reference numbers.

Both coils for spiral winding operate in different modes, in the first unit a periodic profile is formed by winding the thread onto the flow of the reinforcement rod, and in the second unit the thread is rewound and twisted onto the upper spool from a bobbin of a standard format installed on the platform. When the yarn is completely unwound from the unit working to form a periodic profile, a short stop occurs to reinstall the yarn from the reserve spool already wound by that time, then the platform is moved under an empty spool, a new bobbin is installed on the rotating device, and the "threading" process is repeated simultaneously with the formation of a periodic profile. The platform can be moved along the guides by means of rollers, both manually and automatically. The platform can be equipped with fixing elements with bolted fasteners installed along the edges of the platform, which ensures reliable fixation of the platform in its extreme positions during the rotation of the bobbin and rewinding of the roving onto the upper reel and eliminates its displacement due to vibration.
