- the drive wheel is formed in conventional devices as a gear, which is in engagement with the conveyor chain.
- the gear has a fixed pitch that corresponds to the original pitch of the conveyor chain.
- the drive wheel is associated with an auxiliary drive element which is arranged for producing an operative connection between the drive wheel and the conveyor element at least in a partial region of the circumference of the drive wheel between the drive wheel and the conveyor element. Due to the decoupling of the drive wheel on the one hand and the conveying element on the other hand, the dependence of the divisions of drive wheel and conveyor element is canceled, so that the basis for a pitch adjustment is created by the auxiliary drive element.
- auxiliary drive element is arranged at least in a partial region of the drive wheel between the drive wheel and the conveyor element, namely in the contact or engagement region of the drive means and conveyor element, pitch fluctuations of the conveyor chain, which occur predominantly in conveyor chains with old and new chain sections balanced become.
- the conveying element is a
- Conveyor chain and the auxiliary drive element an intermediate chain, wherein the intermediate chain is formed of a plurality of chain links and has slots for changing the pitch.
- the intermediate chain has a loose strand and a solid strand.
- the loose strand is located in the region of the Einfädeins the intermediate chain in the conveyor chain.
- the fixed strand also called tensile strand, is formed in the region of the Ausfädeins the intermediate chain from the conveyor chain.
- FIG. 1 is a side view of a first embodiment of the device or arrangement for conveying in particular rod-shaped articles
- FIG. 2 is a side view of another embodiment of the device or
- the devices and arrangements shown serve to convey, in particular, rod-shaped articles in the tobacco-processing industry, but can also be used for any other type of article or article.
- FIGS. 1 and 2 show the sections of preferred embodiments of an arrangement 10 for conveying rod-shaped products which are relevant to the invention.
- the assembly 10 essentially comprises a formschlüssig drivable conveying element 11 and a device 12 for driving the conveying element 11.
- the conveying element 11 is an endless chain, an endless belt or the like and has on its side facing away from the drive receptacles or troughs 13 for receiving and for holding the articles to be promoted.
- the Förde ⁇ nittel 11 is formed and biased in the embodiments shown as a curved conveyor chain.
- the standing under a bias conveyor chain is formed of a plurality of chain links 14 which are pivotally connected to each other via chain pins 15 formed.
- the conveyor chain can be made of different materials.
- the conveyor chain is made of plastic.
- the conveying element 11 can also be designed as a belt, band or the like.
- the device 12 for driving the form-fit drivable conveying element 1 1 will be described in more detail below.
- the device 12 comprises a conveyor element 11 adapted to the drive element 16.
- the drive element 16 is associated with an auxiliary drive element 17.
- the auxiliary drive element 17 is used for production
- the auxiliary drive element 17 is sandwiched between the drive element 16 and the conveyor element 11 in a contact or effective area IS.
- the Antnebselement 16 thus serves only indirectly to drive the conveyor element 11 by the drive torque is transmitted from the drive element 16 to the auxiliary drive element 17.
- the auxiliary drive element 17 the drive torque is then transferable to the conveyor element 11.
- the auxiliary drive element 17 is an intermediate chain 19.
- Plastic-made intermediate chain 19 is endless. It consists of a plurality of chain links 20 which are hinged together in the region of the chain pin 21 and surrounds the drive element 16 completely. This means that the length of the intermediate chain 19 is greater than the circumference of the drive element 16 is formed.
- Each of the chain links 20 has slots 22. Within the slots 22, the chain pins 21 are guided. In other words, the Kettenbolzerv 21 game within the slots 22.
- the pitch of the intermediate chain 19 is variable. In the stretched state, the intermediate chain has e.g. a different division than in the compressed state. Depending on the slots or their size, the division of each chain link 20 and thus the entire intermediate chain 19 is arbitrary. However, the variable pitch can alternatively be achieved by providing only some of the chain links 20 with slots 22. For example, each second chain link 20 may be provided with two slots 22 each.
- the drive element 16 is formed as a gear 23.
- the gear 23 serves to drive the intermediate chain 19 and has for this purpose (not explicitly shown) teeth which engage in the intermediate chain 19 and drives them over the chain pins 21.
- the intermediate chain 19 surrounds the gear 23 completely or includes this.
- the intermediate chain 19 also surrounds a support roller 24.
- the support roller 24 is arranged offset to the gear 23. This means that the center or pivot points 25 and 26 are spaced apart in parallel planes (see FIG. 1).
- the support roller 24 has a tooth-free, im substantially smooth peripheral surface 27. On the peripheral surface 27 is at least partially, but preferably completely a friction lining 28 is formed or arranged.
- the intermediate chain 19 is on the iris side, that is formed on the gear 23 and the support roller 24 side facing substantially smooth.
- the intermediate chain 19 has a tooth-shaped profile.
- the profile is formed from individual teeth 29, wherein each chain link 20, a tooth 29 is associated.
- the teeth 29 are designed to engage in the conveyor chain.
- the support roller 24 emerges quasi in the intermediate chain 19 and thus also in the conveyor chain. This means that the already provided with a bias conveyor chain snugly against the intermediate chain 19 and the support roller 24, whereby the resulting radial force F leads to the fixation of the current division.
- the radial force F causes friction between the intermediate chain 19 and the support roller 24.
- the endless intermediate chain 19 can be in a loose strand. 30 and a fixed strand 31 divide.
- the loose strand 30 is the part of the intermediate chain 19, which is tension-free, that is provided with a game that is determined by the size of the slots 22.
- the loose strand 30 is located in the region of the Einfädeins the intermediate chain 19 in the conveyor chain.
- the fixed strand 31 is formed in the region of Ausfädeins the intermediate chain 19 from the conveyor chain.
- the drive of the gear 23 takes place in the counterclockwise direction. The direction of rotation is variable.
- the drive element 16 is a roller, roller or wheel 32, which is formed with a substantially smooth or tooth-free peripheral surface 33.
- On the peripheral surface 33 is at least partially, but preferably completely a friction lining 34 is formed or arranged.
- the intermediate chain 19 is similar to the already described intermediate chain 19 formed in accordance with Figure 1, but with the difference that the intermediate chain 19 is formed according to Figure 2 is shorter.
- the length of the intermediate chain 19 is slightly larger than the circumference of the wheel 32.
- the wheel 32 is immersed in the intermediate chain 19 and thus also in the conveyor chain. This means that the already provided with a bias conveyor chain snugly against the intermediate chain 19 and the wheel 32, whereby the resulting radial force F leads to the fixation of the current division. Namely, the radial force F creates friction between the intermediate chain 19 and the wheel 32. This friction also serves to transmit the torque from the wheel 32 to the intermediate chain 19.
- the device 12 does not have to be part of the arrangement 10. Rather, the device 12 can also be used as a separate drive means or in connection with other conveyors.
- the gear 23 is driven in the illustrated side view counterclockwise.
- the torque is transmitted to the intermediate chain 19.
- the intermediate chain 19 is positively driven via the chain pins 21.
- the intermediate chain 19 drives in turn by means of the teeth 29 on the outside conveyor chain.
- the intermediate chain 19 threads in loose strand 30 in the conveyor chain and pushes itself almost automatically to the current division.
- the intermediate chain 19 extends in a length adapted to the pitch of the conveyor chain. Due to the existing due to the bias of the conveyor chain radial force F is generated friction between the intermediate chain 19 and the support roller 24 and the friction lining 28, whereby the current pitch is fixed. In the area of the fixed run 31, the intermediate chain 19 again threads out of the conveyor chain.
- the embodiment according to FIG. 2 works in principle similar to the embodiment just described.
- the intermediate chain 19 drives in turn by means of the teeth 29 on the outside conveyor chain.
- the intermediate chain 19 threads into the conveyor chain and pushes on the current division. This is possible because the intermediate chain 19 is loose due to the existing game immediately before threading. Due to the bias of the
- Conveyor chain existing radial force F creates friction between the injuredJcette 19 and the wheel 32 and the friction lining 34, whereby the current pitch is fixed.
