AI Technical Summary

Problems solved by technology

Preforms become impure due to prolonged contact of preforms with tiny dirt particles, which can lead to low-quality bottles in the subsequent blow molding process

Embodiment Construction

[0054] figure 1 The device according to the invention is shown schematically. The device 1 comprises a storage container 5 . The storage container 5 is filled directly by pouring the delivered packs into the storage container 5 . The storage container 5 is for example held by a holder 19 and rests on a corresponding main pillar. The storage container 5 comprises an opening 9 at its lower end, via which opening 9 the interior 4 of the storage container is connected to the slideway arrangement 2 . The bottom of the container 5 is preferably sloped towards the opening 9 so that the preforms automatically slide into the opening 9 . The height of the opening 9 is set so that not too many preforms are slid out from the storage container each time, and the height of the opening 9 is about 2 to 8 times the diameter of the preform.

[0055] The preforms can slide down via the slideway arrangement 2 towards the discharge conveyor 3 . The inclination angle α of the slideway device 2...

Abstract

The present invention relates to a device and a process for supplying preforms to a blow mold. The device (1) has a storage container for the preforms or a supply container for the preforms, and a discharge conveyor for the preforms or a storage container for the preforms. In order to remove dirt and overflow the preforms, a bent chute having a plurality of perforated openings is arranged between the storage container and the discharge conveyor.

Description

technical field [0001] The invention relates to a device for feeding preforms towards a blow molding machine and a method for feeding preforms. The preform is a preform made of thermoplastic and blow molded in a blow molding machine into a hollow body such as a bottle or container. Background technique [0002] In the prior art, the preforms are slid out of the store container via a surge hopper into an ascending conveyor. The preforms are fed from this ascending conveyor to the blow molding machine via a roller sorter. However, during the bottle manufacturing process, substandard and low-quality bottles repeatedly appeared. [0003] The present invention has found that impurities are the cause of the above-mentioned problems. The storage container is filled directly from the delivery package by dumping the delivery package. Here too, dust, dirt and preform flash that is detached during transfer are introduced. Currently, these contaminants are carried along with the pr...
