Description

(5) DEVICE FOR RECHARGE OF VOLCANIZERS WITH LONG-DIMENSIONAL RUBBER PRODUCTS 1 The invention relates to the manufacture of products from polymeric materials, can be used in rubber products factories and. intended for accumulation of rubber sleeves for their subsequent vulcanization in a vulcanization boiler. A device for recharging cylindrical vulcanizers containing a storage drive with wheels and support posts for mounting it to the loading and unloading station G1 is known. The disadvantage of this device is the low degree of utilization of the useful volume of the vulcanizer, due to the low filling capacity. Closest to the invention is a device for re-charging vulcanizers with long rubber products, comprising a movable cart with wheels, having racks for laying products and locking pivoting devices, and an actuator for loading and unloading products from the C 2 cart. In this device, the racks are made in the form of discs mounted on a common shaft and having radial slots for placing the products to be processed, and the locking devices are freely mounted in guides on the lateral surface of the discs having a window for the passage of the product and an outer locking lug. In addition, on the support racks of the device are mounted lugs that interact with the locking tabs. However, such a device is cumbersome, has a large mass, and it must be moved from the position of unloading to the loading position by the overhead workshop transport. The process of loading and unloading takes a lot of time with the use of manual labor, which increases the number of service personnel. In addition, when vulcanizing in the boiler, a temperature difference is created between the upper and the zones. As a result, the sleeves located in the lower zone of the boiler will always be uncured. and have low quality.

The aim of the invention is to simplify the levers 9.

device design to improve product quality.

The goal is achieved by the fact that in the device for recharging vulcanizers, containing a movable cart with wheels, having racks for laying products and locking devices, and a drive for loading and unloading products from the cart, the racks for laying products are made in the form of a unit of cantilevered shelves hinged mounted on a trolley with an offset to one of its ends to create a constant tilt of the shelf unit, and the drive for loading and unloading products from the trolley is made in the form of swinging levers with mechanical zmami .povorota for their one end interact with the flange unit and the other is kinematically coupled with a mechanism for rotating them.

The locking pivoting devices are made in the form of pivotally mounted rods on each of the shelves with fixed stops and locking knobs fixed to them for turning the rods and fixing them in the required position.

1 shows a device at the loading position, a cross-section; figure 2 is the same, top view; on fig.Z - the same on the unloading position.

The device comprises a trolley 1 with wheels 2, having racks 3 for stacking products k and locking devices 5, and an actuator for loading and unloading products C from trolley 1. Shelves 3 are made in the form of a unit 6 of cantilever mounted shelves 7 pivotally mounted on teleic 1 Hinge 8 is offset to one of the ends of the carriage 1 to create a constant tilt of the shelf unit 6.

The drive for loading and unloading products k from the trolley 1 is made in the form of pivoting levers 9 with a mechanism for turning them, with one end

The locking pivoting devices 5 are made in the form of pivoting rods 15 mounted on each of the shelves 7 with fixed stops 16 and handles 17 to rotate the rods 15 and fix them in the required position.

The device works as follows.

At the loading position, the device has a natural tilt to the right under the action of the force of the right of the block 6 from the hinge 8.

First zagr; Shelf 7. For this purpose, the stoppers 16 of the upper and middle shelves 7 are lowered down at an angle. The limiter 16 of the lower shelf 7 lifts up. The sleeves from the standing table on the right (not shown) are fed to the upper shelf 7 and rolled along the stops 16 to the lower shelf 7. After the lower shelf 7 has been fully loaded, the stopper 16 of the middle shelf 7 is rotated up, thereby directing the sleeve to the middle shelf 7 After loading the middle shelf 7, the stopper 16 of the upper shelf 7 rises up and the sleeves of the upper shelf 7 are loaded.

Thus, the device fully loaded with sleeves is sent for vulcanization into a vulcanization boiler.

After the vulcanization cycle, the device rolls out of the boiler for unloading.

Claims (2)

Unloading is as follows. The drive is turned on. The power cylinder T with gear 12 and toothed rack 13 drives a rotary shaft 10 with levers 9. The shaft starts to rotate, and with the levers 9 on the carriage 1 from the bottom, tilts it around the hinge 8. The tipping angle can be adjusted depending on the diameter of the machined products. In the upturned position, the levers 9 abut 6 shelves interacting with the block, and the other kinematically connected with the mechanism for their rotation. The latter is made in the form of a rotary shaft 10 mounted in bearings 11 and interacting by means of gear 12 mounted on the wapa with a gear rack 13 connected to the power cylinder N. On the 10 V shaft is the lower part of the device to support it. The bottom shelf 7 first unloads. Turn the stopper 16 with the handle 17 down. The sleeves begin to pour out on the stopper 16 onto the table on the left (.in the figure, not shown). Then the limiter 16 of the middle shelf 7 is turned down, and the sleeves are poured out. limiter 16, and then top shelf 7 is unloaded in the same way. After unloading, the drive is actuated in the opposite direction. The shaft 10 with the levers 9 is rotated to its original position, and the device is tilted to its original position by the force of pull of the right side. The device is ready for download. The device, as compared with the known simpler design, requires less manual labor for loading and unloading products. Due to the large capacity increased productivity. The free position of the mandrels on the racks contributes to a better uniform heating of the products and an improvement in their quality. Claim 1. Device for reloading kanizator long rubber products containing movable telekamku with wheels, having racks for stacking products and locking turntables, and a drive for loading and unloading products from the cart, characterized in that, in order to simplify the design of the device to improve the quality of the products, the racks for stacking the products are made in the form of a block of cantilever mounted shelves hinged on a trolley offset to one of its ends to create nnogo inclination of the shelves unit, and the drive for loading and unloading of articles from the cart is designed as a pivoting lever with mechanisms for their turn at one end with a flange interacting unit, and the other end is kinematically coupled with a mechanism for rotating them. 2. The device according to claim 1, characterized in that the locking pivoting devices are made in the form of pivoting rods mounted on each of the shelves with constraints rigidly fixed on them and locking knobs to rotate the rods and fix them in the required position.
