Description

The invention relates to reloading devices used in the manufacture of building materials, and can be used to unload ceramic products of drying cars onto a conveyor. A device for unloading drying trolleys with multi-colored shelves on which pallets with products are arranged contains a fixed cage, inside which is installed a drive-lifting pad for trolleys, a pusher for pushing products from pallets onto a conveyor belt, a pallet end sealer with products and an actuator for feeding the trolleys into the cage 1. The known device has a relatively low productivity and does not ensure a fixed position of the framework on the drying trolley when pushing articles with it. The purpose of the invention is to increase productivity. The goal is achieved by the fact that the device is equipped with a pusher mounted on the lifting pads for stepping the trolley along it and a latch for holding pallets on the trolley shelves consisting of a spring-loaded lever mechanism controlled by a stop fixed on the pusher for pushing products from the pallets. FIG. 1 shows the proposed device, a general view; in fig. 2 is a view along arrow A in FIG. one; in fig. 3 - capture the pallets in the initial position; in fig. 4 grab pallets in working position. The device consists of a stationary stand 1 with a lifting winch 2, inside which a lifting platform 3 is suspended, carrying a drying trolley 4. On the platform 3, a pusher 5 is installed to stepwise move the trolley pushing products from pallets 6 mounted on a drying trolley along a slip 7 on a conveyor belt 8 The trolley 4 is moved by a chain drive 9 and an emphasis 10. The discharge pallet 6 is held by means of a clamp 11 with a hook 12 pivotally connected by a pull 13 with a crank 14, equipped with a pressure roller 15 with a spring 16 returning to Yuka 12 to its original position, the latch 11 interacts with the abutment 17, the pusher 5. In order to equalize the pallet milling cutter 18 is provided.

The device works as follows. The chain drive 9 by means of the anvil 10 feeds into an upright platform 3 an existing trolley 4 with a brick laid on pallets 6. The end facet 18 of the pallets operates, after which the lifting winch 2 is activated, while the platform 3 with the existing wagon 4 rises to the unload position of the two upper pallets 6. The pusher 5 pushes the products along the slip 7 onto the belt conveyor 8. When the pusher moves, -. 5, the stop 17 interacts with the pressure roller 15, and by means of the crankshaft 14 and the pull rod 13 rotates the hook 12 to the position where it holds the pallets b from the shifting. When moving the pusher 5 in the opposite direction, the stop 17 moves away from the pressure roller 15 and the spring 16 returns the hook 12 of the pallets 6 and the entire kinematic connection to its original position. Winch 2 successively raises the platform with the trolley to the unloading position of all the trains of the original trolley 4. After pushing the next rush of the products, the pusher 5 turns on, moving the trolley 4 along the rails of the platform 3 by a step. equal to the distance between p. The pusher 5 is unloaded; - the right half of trolley 4 in the reverse i-KjM order is from the lower pjjyca to the ver. (1. After that, the odor; enio includes the valuable actuator 9, which supplies the loaded BaroiiCTKV 4 to the elevating 3 and then: 1kat (: 5. pushes the empty trolley from the site 3. All mechanisms of the device are connected by the system; 1 sensors.
