Problems solved by technology

Thus, damage to the operating tongs results in a period of time during which the tongs cannot be replaced, or during which the manufacturing unit has to be stopped
This leads to a decrease in production
[0014] These clamps can also be expensive to replace, especially if the order is piecemeal and requires very fast delivery
[0015] Thus, the situation where one or more clamps are damaged is problematic as this leads to reduced production, even downtime, and high costs to be able to quickly replace the clamps

Embodiment Construction

[0090] The term "hollow body" is used hereinafter to denote preforms and final containers which have undergone at least one blow molding operation or stretch blow molding operation.

[0091] refer to figure 1 , shows the operating tongs 1 for operating the hollow body. Such a handling gripper 1 is used in a manufacturing cell of plastic containers comprising the following machines: blow molding machines, filling machines, labeling machines and the like.

[0092] The operating tongs 1 comprise two arms 10 .

[0093] The two arms 10 are designed to be held by holding members (not shown) of the manufacturing unit. For this purpose, each arm 10 comprises cooperating means 20 for cooperating with the retaining member to establish the coupling of the arm 10 with the retaining member.

[0094] The arm 10 serves to grip the hollow body by its neck. These two arms 10 together define a receiving space 100 for receiving the hollow body when it is gripped.

[0095] The hollow body is...

Abstract

The invention relates to an arm (10) of a handling clamp (1) for handling hollow bodies in a unit for manufacturing plastic containers, comprising two arms (10) for being held by a holding member and for gripping hollow bodies, each arm (10) comprising a base (2) having a leading edge (30) for contacting a hollow body, and a jaw (3) extending from the base (2), the arm (10) is formed by: a metal core (4) extending in the jaw (3) after the leading edge (30); -a plastic complement (5) at least partially covering the metal core (4), the plastic complement (5) forming at least the leading edge (30) and being fixed to the metal core (4).

Description

technical field [0001] The field of the invention is that of the maintenance of manufacturing units for manufacturing containers from plastic preforms. [0002] More specifically, the invention relates to handling tongs for handling hollow bodies, which grip the hollow bodies to be transported within the manufacturing unit. Background technique [0003] For the production of plastic containers, such as PET (polyethylene terephthalate) containers, the preforms are first heated in a heating unit before being sent to the forming unit. In the forming unit, a preform is inserted into a mold, and a pressurized fluid is injected into the preform to stretch the plastic material against the walls of the mold to form the container. [0004] In the remainder of the description, hollow bodies will be used to denote preforms and final containers that have undergone at least one blow molding operation or stretch blow molding operation. [0005] In the container manufacturing cell, opera...
