Description

The invention relates to devices for transferring glassware and can be used in glass industry in the production of glasses.

A device for transporting glass products from a glass-forming conveyor to a annealing furnace is known, comprising a pusher with a chain conveyor, enveloping sprockets associated with a drive, a variator, a gearbox and a transmission shaft, and a plate installed in the swinging supports Cl.

The said device does not reliably transfer the blanks of the cups from the transfer conveyor to the receiving one, since the center of gravity of such products is in the upper part due to the profit that is cut off after heat treatment, and when they are pushed by pushing plates, products may overturn. can break up, cause a chaotic arrangement on the trunk, which degrades the quality of their roasting, increases the percentage of the stack. ,

The closest in technical essence and the achieved effect to

The device according to the invention is a rearrangement of glassware from one conveyor to the underlying other conveyor by means of a mechanical pusher and a reducer in the form of a metal tray with an upper stop 23.

A disadvantage of the known device is that the products can only be transported at a certain height due to the upper limiter in the tray. Therefore, blown glass products with a profit having a height of inconsistent dimensions cannot be transferred, and due to the location of the center of gravity of the product in its upper part of the workpiece during transmission from one to another the conveyor will be tilted. In addition, the device does not allow the products to be installed in this order for annealing, which worsens the heat treatment conditions.

The purpose of the invention is to increase the reliability of transferring blown blanks with a profit and to improve the annealing conditions due to their orientation.

The goal is achieved by the fact that the device for transferring glassware from one conveyor to another, below, contains one frame and a descender, located between the conveyors, equipped with a sensor for the presence of glassware and contactless end switches, and the reducer is made of inclined guides along the profile of glassware with reversible arrows and safety devices installed under them in the form of levers, at one end of which there are down-concave legs, and on the other flags interacting with one of the contactless limit switches. Moreover, in the device, the sensor of the presence of glassware can be hinged on the frame under the safety device at a distance equal to the height of the glass products, and made with a return element at the end. The inclined guides can be made of heat insulating material and are placed with a step equal to the diameter of the glassware. FIG. 1 shows the proposed device, a side view of FIG. 2 the same in terms of; in fig. 3 is a view along arrow A in FIG. 2; in fig. 4 an electric switch control circuit; A device for transmitting glass products contains a pneumatic cylinder 1 driven by an inclined chute 2 which receives glass decks 1 and 3 with profit 4 from a blow molding machine 5, an auxiliary conveyor 6 an orientation table 7, an article supply conveyor 8, conveyors are driven into motion by a gearmotor 9 and a chain 10, conveyors can change the angle of inclination of the orientation shaft depending on the mass of glassware 3. At the end of the conveyor a reducer is installed, transmitting the glass whether on the underlying conveyor in the form of Lera 11 annealing. A coil reducer made of inclined guides 12, made along the profile of glassware 3 and cross-over arrows 13 installed in them for dividing the current of products into even and odd rows. The lower also includes traversal devices installed under the guides, made in the form of levers 14, at one end of which are placed concave down legs 15 and 16, and on the other - flags 17 and 18. The device has non-contact limit switches, one of which 19 interacts with a sensor 20 Neschy glassware 3, made, for example, with a return element 21 in the form of a load or spring at the end and installed hingedly to the frame 22. under the inclined guides 12. Other non-contact limit switches 23 and 24 interact with the flag and 17 and 18 catchers glassware. The catchers are driven by pneumatic cylinders 25 and 26. The throw-over arrows 13 are actuated by a pneumatic cylinder 27. The guides 12 are made of thermal insulating material, and are spaced apart from each other. another equal to the diameter of glassware. The sensor 20 for the presence of glassware is placed under catchers and a distance equal to the height of glassware 3. The automatic blower 5 periodically feeds four cup blanks 3 onto an inclined tray 2, actuated by a pneumatic cylinder 1, throws the glass blanks onto an auxiliary conveyor that feeds them on the table 7 orientation. On the table, the orientation of the workpiece take a vertical position. Oriented glass products are supplied to the conveyor 8 of the product feed. The force from the gear motor 9 is transmitted through the chain 10 simultaneously to both conveyors 6 and 8. Glass products from the feed conveyor in a vertical position are fed to a descender, where along inclined guides 12, for example, along odd rows, they slip into their lower part. The product with its own weight presses the catcher lever 14, then enters its legs 16. While the product begins to press the lever, the flag 18 located at its end enters the non-contact limit switch 24 and the presence sensor 20 commands the pneumatic actuator .26 for lowering the catcher lever and translating the arrows 13. The product delivered to the annealing sheet 11 gradually comes off the catcher legs 16. At this time, the newly received cup blanks are transferred to even rows of guides 12 by the sliding arrows AG with a flag 17 and fall into the catcher's feet. The flag 17 enters the non-contact limit switch 23, and the presence sensor issues a command to the pneumatic cylinder 25 to lower the catcher lever and translate the arrows 13. The second ends of the catcher levers have flags 17 and 18, which alternately enter the proximity switches 23 and 24 and the command from they are fed to pneumatic cylinders 25 and 26 for lifting the even and odd catcher levers. The products on the annealing layer are shifted relative to each other by the distance selected for each product, set in staggered order. which improves the annealing mode and eliminates the fight products during the installation.
