Description
Technical field
The utility model is specifically related to a kind of chain broken chain detecting device of automatic production line.
Background technology
Along with the continuous increase of cost of labor, increasing conventional production equipment starts the manufacturing line replacement that is progressively automated.And chain conveying is as a kind of economy, stable, reliable, easy to maintenance type of transmission, also certainly will be widely used in various manufacturing line.And for automatic production line, owing to considering safety factor, all devices has all carried out strict physical isolation when mounted with personnel, some hidden danger existed in manufacturing line have so just been made to be found by maintainer in time, such as chain chain rupture.
Utility model content
Therefore, the utility model is for chain chain rupture in prior art, nobody finds and there is the technical matters of potential safety hazard, object is to provide a kind of chain broken chain detecting device that automatically can identify chain whether chain rupture, this device continues to report to the police so that maintainer's Timeliness coverage processing after discovery chain rupture, various automation chain type conveying device can be widely used in, on the full-automatic manufacturing line of especially robot manipulation.
Chain broken chain detecting device of the present utility model, comprising:
One spring;
One chain pipe link, its lower end is connected with described spring, and upper end can connect for described chain;
One permanent seat, described chain pipe link penetrates in described permanent seat movably;
One chain position probing block, to be installed on described chain pipe link and position between described permanent seat and described upper end;
One tensioning detecting sensor, is fixedly arranged on described permanent seat, for described chain position probing block during the described chain tension of detection;
One chain rupture detecting sensor, to be fixedly arranged on described permanent seat and to be positioned under described tensioning detecting sensor, for described chain position probing block after the described chain chain rupture of detection.
Wherein, described permanent seat has:
Plate on one, described chain pipe link penetrates movably on the upper plate of described permanent seat, described upper plate has a sensor contiguous block, described tensioning detecting sensor and described chain rupture detecting sensor are fixedly arranged on the sensor contiguous block of described upper plate;
At least two back-up blocks, for the described upper plate of support, be fixedly arranged on the below of described upper plate symmetrically, jointly form the inner chamber of a hollow with described upper plate, described spring is positioned at described inner chamber.
Chain broken chain detecting device of the present utility model, by increasing spring and sensor, and sensor model number is connected in PLC system, realize the real-time monitoring to chain state, once there is chain chain rupture, chain broken chain detecting device of the present utility model can send a signal to PLC control system the very first time and automatically cut off the operation of manufacturing line, sends lasting warning sound, so that maintainer carries out maintenance work in time, avoid larger economic loss.Chain broken chain detecting device of the present utility model has the advantages such as structure is simple, result of use is obvious, Installation and Debugging are simple, cost is extremely low, safe and reliable.

Detailed description of the invention
As shown in Figure 1, be chain broken chain detecting device 30 of the present utility model, comprise:
Permanent seat 31, shape is
there is upper plate 311, two back-up block 312, for the upper plate 312 of support, be fixedly arranged on the below of plate 311 symmetrically, jointly form the inner chamber 313 of a hollow with upper plate 311.Spring 34, is positioned at the inner chamber 313 of permanent seat 31.Chain pipe link 32, penetrate the upper plate 311 in permanent seat 31 movably, lower end is connected with spring 34, and upper end can connect for chain 23.Chain position probing block 33, to be installed on chain pipe link 32 and position between the upper plate 311 and the upper end of chain pipe link 32 of permanent seat 31.Tensioning detecting sensor 35, is fixedly arranged on the sensor contiguous block 314 on plate 311, for the chain position probing block 33 during detection chain tension.Chain rupture detecting sensor 36, to be fixedly arranged on the sensor contiguous block 314 on plate 311 and to be positioned under tensioning detecting sensor 35, for the chain position probing block 33 detected after chain chain rupture.
As shown in Figure 1, during assembling first by the spring 34 on chain broken chain detecting device 30 through on chain pipe link 32, and then by chain pipe link 32 through permanent seat 31, again chain position probing block 33 is contained on chain pipe link 32, then chain pipe link 32 is connected with the chain 23 on transmission device 20.Permanent seat 31 is fixed on arbitrary plane, tensioning detecting sensor 35 and chain rupture detecting sensor 36 are contained on permanent seat 31.After chain 23 is connected with drive end sprocket wheel 21, driven end sprocket wheel 22, the contiguous block 12 in load 10 is connected with the other end of chain 23, finally the clump weight 11 in load 10 is connected with chain connecting block 12.
When system is in normal operating condition, the permanent seat 31 inside chain broken chain detecting device 30 can be fixed on a specific plane, now because the effect of load 10 makes the chain 23 of whole transmission device 20 be in tensioning state.Now spring 34 is due under tension, can tightly be pressed on permanent seat 31.At this moment the chain position probing block 33 be contained on chain pipe link 32 is in the high position shown in Fig. 2, and is just in time in the detection range of tensioning detecting sensor 35, and not in chain rupture detecting sensor 36 detection range.Now tensioning detecting sensor 35 can by signal feedback to control system, indication equipment normal operation.Once there is chain 23 chain rupture, the pulling force meeting pop-off suffered by spring 34, now spring 34 can flick by nature, and the chain after driving chain pipe link 32, chain position probing block 33 and part to disconnect moves down together.As shown in Figure 3, along with spring 34 flick and mobile after chain position probing block 33 will be in low level, and just in time leave the detection range of tensioning detecting sensor 35, be in the scope of chain rupture detecting sensor 36 detection.Now chain rupture detecting sensor 36 can by signal feedback to control system, and control system will be run by auto-programming cutting system, and continue to send warning prompt tone, and indication equipment is abnormal.Now maintainer can go to deal with problems before the very first time, avoids the manufacturing line loss brought out of service for a long time.
