Embodiment Construction

[0028] figure 1A device 1 for feeding preforms to a blow molding machine, for example for producing PET bottles, is shown. The device comprises a collection container 2 in which a stock of preforms is provided. The preforms are transported from the collection container 2 via a vertical conveyor 3 to the input of the conveyor 4 . The other end of the conveyor device 4 , namely the output end, is arranged above a sorting device 5 , wherein, for an orderly and as disturb-free delivery of the preforms from the conveyor device 4 to the sorting device 5 , there are two The supply device 6 arranged between. From the sorting device 5 the preforms are sorted to a second conveying device 8 by means of which the preforms are conveyed into a blow molding machine (not shown).

[0029] In Figure 2 is shown the figure 1 The cross-section of the side view of the detail X shown in , wherein the flow direction of the preforms is each indicated by means of the drawn arrows.

Abstract

The invention relates to a device for feeding preforms to, for example, a blow molding machine for the manufacture of containers made of thermoplastic material, having a transfer device, a supply device and a sorting device, the transfer device feeding preforms from The preforms of the piece reserve, the supply device is supplied with preforms by the conveying device, the preforms are sorted in the sorting device and conveyed at a conveying speed along the conveying direction, wherein, The conveyor device is arranged to end above the sorting device, wherein the supply device has a receiving area on the input side and a handover area on the output side, the preforms coming from the conveyor device arrive at the receiving area. The area through which the preforms reach the sorting device is characterized in that the supply device further comprises an orientation area with an orientation device, which is configured such that in the orientation area Orienting the flow of preforms along the direction of the flow of preforms in the sorting device (conveying direction) and thereby passing the preforms in an oriented manner through the delivery area .

Description

technical field [0001] The invention relates to a device and a method for feeding preforms to a machine for producing containers made of thermoplastic material, wherein the containers are shaped by blow molding pressure. Background technique [0002] During the molding of containers by blow molding pressure, preforms made of thermoplastic material, for example PET (polyethylene terephthalate), are supplied to the various processing stations within the blow molding machine . Typically, such blow molding machines have a heating device for heating the preforms and a blowing device, in the region of which the previously temperature-treated preforms are expanded into containers by biaxial orientation . The expansion takes place by means of compressed air which is introduced into the preform to be expanded. DE-OS 43 40 291 describes the technical sequence of the method for such an expansion of preforms. The basic design of a blowing station for container forming is described i...
