Description

Изобретение относитс к устройствам дл изготовлени резино-кордиых оболочек, оно может быть ).1ьзовано дл нрнкатки резиновых лент к резнно-кордным обо.ючкам с вентилем, например, нротектора к баллонам иинно-пневматнческих муфт.The invention relates to devices for the manufacture of rubber-cord shells, it can be). It is suitable for rolling rubber bands to cordage windows with valves, e.g., a nitro-vector to cylinders of pneumatics couplings.

Известно устройство дл прикатки резиновых лент к резино-кордн1) оболочкам, содержащее шарнирно смонтированн)е а основании подпружиненные рычаги со свободно вращающимис центральными и боковыми прикаточ1п 1ми роликами 1.A device for stitching rubber bands to rubber cords, 1) shells, comprising spring hinged levers with freely rotating central and lateral attachment rollers 1, is hinged on the base.

В известьом устройстве при ос ществлеиин нрикатки барабан с обрабатываемой резино-кордной обе)лочкои неременгаете к нрикаточным ро;1икам, что затрудн ет обсл живание устройства.In a lime device, when the drum is rolled out with the rubber-cord being processed, both the barrel and the drum are not shaken to the clippers, which makes it difficult to maintain the device.

Этот ь:едостаток устранен в другом нзвестио .м устройстве, содержащем шарнирно с.1онтирова:11 1о на оенованш- раму со свободно вран1а10 ди.1ис боковыми прикаточиыми рол1и ами, шарннрно с.монтированный на ней носредством иодиружинеиного рычага свободно вращающийс центра.чьиый прикаточный р(1.-1ик и ме.ханизм дл неревода рамы в рабочее положение 2.This: the rest of the device is eliminated in another device that contains a hinged p. 1: 11 1 on a frame with a freely wedged 10 d.1 with side stitching rollers, pivotally mounted on it by means of a single arm and rotating arm, a free-rotating center. p (1.-1ik and meh.khanizm for not having the frame in working position 2.

Однако указанное стройство не может быть использовано дл обработки резино-кордиых оболочек с выстунакмцим вентилем,так как в этом случае з-за последнего lUiiTpayibиа чаеть ленты остаетс ненрпкаташим.However, this device cannot be used to handle rubber-cord shells with a valve, since in this case, the last lUiiTpayib and the tape remains unprotected.

Цель изобретени - обеспечение воз.можноети обработки резино-кордных обо.ючек с выстунающи.м вентилем,The purpose of the invention is to provide the possibility of handling the rubber cord obyuchek with a valve,

Поетавленна цель достигаетс те.м, что хстройство снабжено механизмом нодьема центрального прикаточного ролика ири иодходе вентил в зону прикатки. Л е анизм подъема вынолнен в виде смонтированного на подпружиненном рычаге копирного ролпка и взаимодействуюитего с ним ,1 к)щего диска, вращающегос синхронно с обрабатываемой обо.ючкой.The potaled goal is achieved by tem that the structure is equipped with a nodiem mechanism of a central stitching roller and valve in the rolling zone. The lift is carried out in the form of a copier roller mounted on a spring-loaded lever and interacting with it, 1 k) of a drive disk rotating synchronously with the processed skidding unit.

На фиг. 1 изображено предлагаемое устройство; на . 2 - то , вид в плане; на фиг, 3 - расположение прикаточных роликов в момент захода участка с вентилем в ЗОН} прикатки.FIG. 1 shows the proposed device; on . 2 is a plan view; in FIG. 3, the arrangement of the stitching rollers at the moment of entering the section with the valve in the ZON} of the rolling process.

Claims

The proposed device contains a frame 1 with frame 2, which is pivotally attached to it by means of axis 2, pa which, using an axis 4 cm), types freely rotating side press rollers 5 and 6. On axis 4, the arms 7 and 8 are hingedly mounted, the last of which is spring loaded 9 relative to the frame 3. On the levers 7 and 8, by means of the axis 10, a freely rotating central stitching roller 11 is mounted. The device has a mechanism for raising the central stitching roller, which is designed as mounted on a spring-loaded lever 8 a copy roller 12 and a control disc 13 interacting with it, rotating synchronously with the casing being machined. The disk 13 is made with flat “a. The mechanism for shifting the frame 3 to the working position is made in the form of a cylinder 14 pivotally connected to the frame 3 via a system of hinged levers 15. When the device is operated, the rubber-sheath to be processed 16 with the valve 17 is mounted on the drive drum 18, on the axis of which is mounted and control disk 13. The device operates as follows. The frame 3 is lifted by the cylinder 14 and the rollers 5, 6 and 11 press the protector 19 against the rubber-cord sheath 16 located on the drum 18, and the roller 12 presses the spring 9 onto the control disk 13. As the drum 18 rotates, the protector 19 rolls to the sheath 16 three rollers 5, 6 and 11. When the valve 17 approaches the roller 11, the cam roller 12 hits the track “of the disk 13 rotating synchronously with the drum 18, and the spring 9, which presses roller 12 to the flat”, rolls roller 11 from the tire tread, the valve passes 17. The rollers 5 and 6 remain in the working position. With further turning of the drum 18 with the disk 13, the roller 12 goes to the cylindrical part of the disk 13 and turns the lever 8, the roller 11 moves to the tread. The roller 11 continues to roll in the center of the tread. The proposed device allows the central part of the casing to be rolled in, which improves the quality of the bonding of the applied rubber tape to the casing and, consequently, the quality of the finished rubber-cord casing. Claim 1. Gadget for stitching rubber tapes to rubber-cord shells containing a frame hingedly mounted on the base with freely rotating side press rollers, hingedly mounted on it by means of a spring-loaded lever a freely rotating center press roller and a mechanism for translating the frame into a working position , characterized in that, in order to enable the processing of rubber-cord shells with a protruding valve, it is equipped with a central prikatoch lifting mechanism th roll when approaching fan in the stitching zone. 2. The device according to claim 1, characterized in that the lifting mechanism is designed as a copier roller mounted on a spring-loaded lever and a control disk cooperating with it, rotating synchronously with the shell being processed.
