Example

[0064] According to the first embodiment of the present invention, the detection mechanism 36 is formed by a measuring instrument for measuring the potential difference, such as a voltmeter, the terminal of which is electrically connected to the cam 32 and the other terminal of which is electrically connected to the cam follower 30A , 30B. The second terminal of the detection mechanism 36 may be electrically connected to the arm 18, for example.

[0065] When the cam 32 is properly insulated from each cam follower 30A, 30B by the insulating layer 34, a detection mechanism 36 formed by a voltmeter thus measures a potential difference equal to P2-P1.

[0066] When a voltage dip is observed, this means electrical contact between at least one of the cam followers 30A, 30B and the cam 32 . From this, it is inferred that the contact layer 34 is broken. The appropriate action is thus initiated.

[0067] The detection mechanism 36 is connected, for example, to an audible or visual ...

Example Embodiment

[0069] According to the Figure 5 In the second embodiment of the invention shown above, the detection mechanism 36 is formed by an electric dipole, such as a lamp or LED, capable of detecting the flow of current and is interposed between the source of the second electrical signal "P2" and the cam 32 in the circuit. Thus, when the contact layer 34 is damaged or broken, electrical contact between the cam 32 and at least one of the cam followers 30A, 30B causes current to flow inside the electric dipole.

[0070] According to a variant of the invention not shown, the opening and closing of the jaws of the clamping part can be controlled by means of a cam follower supported by the clamping part cooperating with a fixed cam. The invention described above can thus be applied to such control components.

[0071] Such a device 10 thus allows rapid detection of a break in the contact layer 34 .

[0072] In addition, the return spring 28 is also made of a conductive material, and th...

Abstract

The invention relates to a device for transporting hollow bodies, which comprises: - at least one means for grasping a hollow body, said means comprising at least one cam follower (30A) made of an electrically conductive material; - at least one fixed cam (32) which is intended to engage with the cam follower (30A), the cam (32) being made of an electrically conductive material; - a contact layer (34) which is made of an electrically insulating material and is interposed between the cam (32) and the cam follower (30A); characterized in that the cam follower (30A) is connected to a first electrical signal (P1) whereas the cam (32) is connected to a second electrical signal (P2), a member (36) being positioned so as to detect electrical contact between the cam follower (30A) and the cam (32).

Description

technical field [0001] The invention relates to a conveying device for conveying hollow bodies made of thermoplastic material. [0002] The invention relates more particularly to such a conveying device for conveying hollow bodies made of thermoplastic material, comprising: [0003] - at least one gripping part for gripping the hollow body, intended to be moved along a defined track and comprising at least one cam follower made of electrically conductive material; [0004] - at least one fixed cam controlling the gripping part, arranged along at least a section of the track of the gripping part and intended to cooperate with the cam follower, the cam being made of electrically conductive material; [0005] - A contact layer made of electrically insulating material and interposed between the cam and the cam follower. Background technique [0006] Manufacture of containers of thermoplastic material, such as bottles, from preforms that are thermally conditioned and then molde...
