Definitions
- the invention relates to a conveyor system for hanging objects according to the preamble of claim 1.
- a conveyor system is known from EP 1690811 B1, in which a strand of a revolving drive chain that can be driven in a conveying direction is arranged in a transport rail.
- the drive chain is designed with downwardly protruding pins.
- Below the drive chain there are holding elements mounted on rollers in the transport rail, which are designed at their lower end with an opening for receiving the hook of a hanger with a piece of clothing.
- the holding elements each have stops at their upper ends, which protrude between adjacent bolts, so that a positive drive connection is established between the drive chain and the holding elements.
- the conveyor system referred to as a transport system, has no device that would allow holding elements to accumulate while the drive chain is being driven uninterruptedly.
- EP 2363358 B1 discloses a conveyor system capable of accumulating, in which a run of a revolving drive chain that can be driven in a conveying direction is arranged in a transport rail.
- the drive chain is slidable in the chain guide against the force of gravity and is designed with upper coupling parts projecting downwards.
- Below the drive chain holding elements mounted on rollers are provided in the transport rail.
- the holding elements each have lower coupling parts at their upper ends, so that a drive connection is established between the drive chain and the holding elements. When the holding elements are dammed up, the upper coupling parts climb up onto the lower coupling parts and the drive connection is reduced.
- EP 623497 B1 discloses an accumulating conveyor in which carriers for goods to be conveyed are mounted on a mounting rail by means of rotatably mounted rollers and can be driven in a conveying direction by a traction means in the form of a friction belt also mounted on the mounting rail.
- a stop device with a holding finger is provided, which can be moved into the movement space of the carrier and acts on a spreading device attached to the carrier, causing a lateral pivoting and thus lifting the carrier from the friction belt.
- DE 40 17 821 C2 discloses a conveyor system in which carriages for conveyed goods guided on running rails are conveyed with the aid of bristles which are arranged as drivers on a driven belt strand and come into frictional contact with part of the carriage.
- the carrier carriage is stopped, while the bristles continue to run regardless and exert a residual frictional force on the carrier carriage.
- the bristles are intended to act like a slipping clutch, which represents a drive connection that can be released without any other criteria and allows the conveyed item to be accumulated without gaps, regardless of its thick dimensions.
- the type of drive connection in which the drivers engage the bristles and are moved relative to one another during an accumulation operation subjects the brushes to significant wear.
- DE 297 09 547 U1 discloses an overhead conveyor system in which hanger carriers mounted on rollers and driven by a conveyor chain located above them can be moved on a main conveyor line.
- drivers are attached to the conveyor chain at regular intervals, which cooperate with rigid coupling elements on the bracket carriers.
- bracket carriers can be diverted from the main conveyor line to the side onto a buffer line, which releases the drive connection.
- the further drive of the derived stirrup carriers is effected by a separate drive device.
- a stopping device referred to as an accumulation barrier, is provided, on which hanger carriers accumulate.
- the requirement for the drive of the shackle carriers to be accumulated in the accumulation section to have to allocate its own complicatedly constructed drive device makes the overhead conveyor system extremely complex.
- a conveyor system is known from DE202017107908U1, in which a strand of a revolving drive chain that can be driven in a conveying direction is arranged in a transport rail.
- the drive chain is designed with flat-down top clutch magnets.
- Below the drive chain holding elements mounted on rollers are provided in the transport rail.
- the holding elements each have lower coupling magnets at their upper ends.
- the upper and lower coupling parts are coupled to each other without contact.
- the drive connection between the drive chain and the holding elements is created by the magnetic forces.
- the disadvantage of the conveyor is a limited transport speed due to the weak drive connection between the upper and lower coupling parts.
- the system can also fail when conveying heavy objects.
- Another disadvantage is the formation of dust in the system due to the magnets.
- EP 2752378 B1 discloses an accumulation-capable conveyor system in which a conveyor chain driven in a conveying direction with friction rollers is arranged in a conveyor rail.
- the drive chain is designed with push bodies that are elastically resilient downwards.
- holding elements mounted on rollers are provided in the transport rail.
- the holding elements each have lower coupling parts at their upper ends, so that a drive connection is established between the drive chain and the holding elements.
- rise when damming up the holding elements the springy thrust bodies of the chain and rub over the couplings of the holding elements.
- the disadvantage of the conveyor is high noise, high energy consumption and strong pressure when piling up the holding elements.
- a resilient thrust body breaks off, the part can jam in the transport rail, which can lead to the failure of the transport system.
- WO 2017109042A1 discloses an accumulation-capable conveyor system in which a conveyor chain driven in a conveying direction is arranged in a transport rail.
- the drive chain is designed with driver elements that are laterally resilient downwards.
- Adapters mounted on rollers are provided in the transport rail below the drive chain.
- the adapters each have coupling parts at their upper ends, so that a drive connection is established between the drive chain and the adapters.
- the disadvantage of the conveyor is high volume and strong pressure when piling up the adapters, which can lead to wear and tear of the system.
- a resilient thrust body breaks off, the part can jam in the transport rail, which can lead to the failure of the transport system.
- the invention is based on the object of further developing the generic conveyor system in such a way that a multifunctional, reliable, low-wear, low-wear system that automatically adapts to the operating requirements for sorting, conveying, accumulating and storing different objects is created with few parts.
- the means for the vertical 16 displacement of the upper coupling parts 12 for closing and releasing the drive connection with the lower coupling parts 13 consist of a bearing 2 for the drive chain 4 that is installed in the transport rail 1 so that it can be displaced vertically 16.
- the stepless displacement of the bearing 2 is Solved using a drive 3, which is preferably an inexpensive pneumatic drive 3.
- 1 stops 9 are provided in the transport rail.
- sensors for controlling the drives 3 are provided to produce an automatic operation of the conveyor system. The sensors record the operational process and, depending on the current requirements, they control the conveyor system.
- a simple, inexpensive one-piece construction of the bearing 2 is provided, which is milled or extruded.
- a further advantageous embodiment of the bearing 2 with a stable base body 15 is achieved with claim 7 .
- Advantageous drive connections of the upper coupling parts 12 and lower coupling parts 13 for different requirements for sorting, conveying, accumulating and storing objects 6 are achieved with claims 8 to 10 .
- the fully automatic possibility of alternately conveying and accumulating the objects 6 is particularly advantageous.
