Individual tight chain type travel lines that drive more
Technical field
This utility model relates to a kind of individual tight chain type travel line that drives more, belongs to automation of industry logistics load transfer device technology.
Background technology
In the manufacturing line of modernized factory, the mode of movement of workpiece is a lot, and wherein chain type travel line (aerial or ground) is more commonly used.In order to satisfy the technological requirement of manufacturing line, travel line is all long, needs to adopt a plurality of actuating devices to realize the normal smooth running of a conveyer chain.Existing technology is even for the chain tension that makes whole conveyer chain, and chain is lax, will add in the actuating device back usually that a tightening device absorbs because the chain that actuating device causes undue lax.How many actuating devices whole travel line has just to be equipped with the tightening device of same quantity.
We can understand that from existing travel line version a strip transmission line has a plurality of actuating devices and tightening device.Usually actuating device is a linear pattern, can be arranged on any position of manufacturing line according to the needs of manufacturing line.But tightening device must be " U " type version, and volume is bigger, is difficult to adapt to the integral layout of whole production line.Influence the smooth running of whole conveyer chain, and increase unnecessary investment cost.
Summary of the invention
The purpose of this utility model is to provide a kind of whole travel line both a plurality of actuating devices can be set, and only needs the travel line of single tightening device, realizes the rationally distributed of manufacturing line and individual the tight chain type travel line of many drivings that operates steadily.
In order to achieve the above object, the technical solution of the utility model is: a kind of individual tight chain type travel lines that drive more, comprise conveyer chain and a plurality of actuating device, described actuating device comprises an active drive device and other driven actuating device, is provided with tightening device behind the active drive device; Described driven actuating device comprises motor, reductor and friction clutch, and Ortlinghaus plate clutch is installed on the output shaft of reductor, and conveyer chain cooperates with the output shaft transmission.
Also be provided with the adjustment spring on the described Ortlinghaus plate clutch.
After adopting said structure, load onto Ortlinghaus plate clutch for the sprocket wheel of original driven actuating device, the power that driven actuating device transmits drives the chain wheel drive chain by Ortlinghaus plate clutch.The friction force size of power-transfer clutch can arbitrarily be adjusted by the spring on the power-transfer clutch, also promptly adjust the size of friction force according to the running state (the degree of tightness situation of the chain before the actuating device) of manufacturing line conveyer chain, thereby all permanent operation of the chain that reaches whole conveyer chain, do not have relaxation, and no longer need to increase tightening device.The position of driven actuating device can arbitrarily be set according to the needs of manufacturing line, and does not influence the layout of whole production line.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the driven actuating device of the utility model.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.
As shown in Figure 1, 2, individual tight chain type travel line that drives of the present utility model more, comprise conveyer chain 1 and a plurality of actuating device 2, described actuating device 2 comprises an active drive device 2-1 and other driven actuating device 2-2, is provided with tightening device 3 behind the active drive device 2-1.
As shown in Figure 2, described driven actuating device 2-2 comprises motor 4, reductor 5 and friction clutch 6, and friction clutch 6 is installed on the output shaft 5-1 of reductor 5, and conveyer chain 1 cooperates with output shaft 5-1 transmission, can adjust tensioning to conveyer chain 1.
As shown in Figure 2, also be provided with on the described friction clutch 6 and adjust spring 7, can adjust the friction force of friction clutch 6 as required, reach the effect of different driving power.
As shown in Figure 1, 2, when the utility model used, the motor 4 of described driven actuating device 2-2 rotated, and gave Ortlinghaus plate clutch 6 by the transmitting power of transmission shaft 5-1 after slowing down by reductor 5, gave driving chain 1 transmission of power by Ortlinghaus plate clutch 6 again.Adjust the thrust of spring 7 according to the operation conditions of manufacturing line, thereby adjust the friction force of friction clutch 6, thereby obtain all permanent operation of chain that different propulsive efforts reaches whole conveyer chain, do not have relaxation, and no longer need to increase tightening device.The position of driven actuating device can arbitrarily be set according to the needs of manufacturing line, and does not influence the layout of whole production line.
