Problems solved by technology

Of course, this interruption results in a loss of yield for the method due to the reduction in production time
In addition, the products obtained directly after the lubrication of the parison mold are usually defective and must be rejected according to the table shown on page 10 of the certification of the document WO2007138226
[0015] Moreover, the lubrication methods in the prior art, whether performed manually or by robots, have an impact on the service life of the mold through oxidation resulting from the deposition of the lubricating layer

Embodiment Construction

[0068] therefore, figure 1 Lubrication performed by the pressure blowing or blowing production method according to the invention is shown. The parison mold comprises two half-molds 101 , 102 with a double part closed at each production cycle, two glass gobs 103 loaded into the parison mold by gravity. After the two halves 101 , 102 of the parison mold are opened, a transfer arm 104 is used to transfer the gob 103 from the parison mold to the blow mould. The transfer arm 104 is able to perform a bi-directional movement between the parison mold and the blow mold by passing between the two halves 101, 102 of the parison mold, in order to transfer the preformed gob 103 from the parison mold to the blow mold. plastic mold.

[0069] The method includes lubrication of the parison mold including spraying by nozzles 105a, 105b carried by a Y-arm 105 of a mobile robot moving along the parison mold side of the I.S. machine. The mobile robot is configured to:

Abstract

A method for producing a hollow glass product by an I.S. machine, said method being a press-blow or blow-blow method and implementing at least one parison mould and one blow mould, said method comprising the lubrication of said parison mould, the lubrication comprising spraying via a nozzle (105a, 105b), said nozzle (105a, 105b) being carried by the arm (105) of a mobile robot movable along the parison mould side of the I.S. machine, characterized in that said mobile robot is configured to (iv) bring said nozzle (105a, 105b) into the lubricating position after the glass gob has left the parison mould for the blow mould; (v) spray the lubricant into said parison mould; (vi) withdraw said nozzle (105a, 105b) from the lubricating position before the transfer arm returns between the two half-moulds of the parison mould.

Description

technical field [0001] The present invention relates to the production of hollow glass products such as bottles, vials or jars. Background technique [0002] This production implements I.S. [individual part] machines, where each part is designed to process one or more gobs simultaneously, each gob being received and processed in a dedicated parison mold (and then a dedicated blow mold). [0003] The parison mold consists of two mold halves defining vertical joint surfaces. [0004] The two mold halves are closed on the collar mold at the lower end of the parison mold. The parison mold also includes a stamp whose rising movement produces the punching of the parison. [0005] The loading of the gob into the parison mold is performed by gravity from its open upper end. [0006] In the press-blow method, this loading is performed in the bottom position of the stamp. The upper end of the parison mold is then closed by the bottom, and the stamp moves from the collar mold towar...
