Definitions
- the invention relates to a conveyor roller for conveyor systems for conveying containers, pallets, piece goods and the like.
- the invention further relates to a method for producing and balancing, in particular dynamic balancing, such a conveyor roller.
- Conveyor rollers are used for different purposes in logistic applications. Typical areas of application are, for example, mail distribution centers, the food processing industry, assembly lines in the electronics industry, machine linkages in automation, manufacturing systems, shipping and packaging lines, order picking systems for large pharmaceutical distributors, pallet transport in beverage distribution, cargo handling or cash desks in supermarkets.
- a conveyor line is regularly built up, which consists of several rollers arranged side by side, the upper circumferential surface of which serves in each case to receive the conveyed material.
- idle rollers are arranged in these conveyor lines, which are driveless and are only rotatably supported in a conveyor frame.
- driven conveyor rollers which are motor-operated and are set in rotation by an electric drive unit, are arranged in these conveyor lines.
- the motor-driven conveyor rollers serve on the one hand to transport the material to be conveyed directly over the outer peripheral surface of their roller body.
- a transmission element for example a belt drive, by means of which the motor-driven conveyor roller also rotates one or more idler rollers in order to also drive the material to be conveyed via its outer peripheral surfaces.
- Conveyor rollers are preferably constructed in such a way that the roller body is hollow at least in sections and in particular has a hollow end, preferably two hollow ends.
- the drive unit is preferably arranged within an interior of the roller body. If the drive unit is arranged inside the roller body, no mechanical components arranged outside the roller body are required to generate the rotation of the roller.
- a drive unit arranged in the interior of the roller body can, for example, have a clutch unit which is designed and arranged to transmit a torque from the drive unit to an inner circumferential surface of the interior of the roller body.
- Drum motors of the type mentioned at the beginning and their drive units are used in conveyor systems which often have, in addition to drum motors, conveyor rollers without an electrical drive unit.
- a conveyor belt is placed on the drum motors and / or conveyor rollers, e.g. a conveyor belt, a plastic link belt or a modular or modular belt.
- the goods to be transported can rest directly on the drum motors and / or idle rollers.
- one or more conveyor rollers are set in rotation by a drive.
- the conveyor rollers have a drive unit, such a conveyor roller with drive unit also being able to be referred to as a drum motor.
- Conveyor rollers can also be set in rotation, for example, by a drive belt which is connected to a drive unit or a drum motor.
- Conveyor rollers, in particular drum motors and / or idle rollers are known, for example, from DE 10 2006 054 575 A1, EP 1 02 1664 B1, DE 20 2009 012 822 U1, DE 10 2015 104 130 or DE 10 2015 114 030 from the applicant.
- conveyor rollers In particular in the food processing industry, where for example milk products, fish or meat are transported, conveyor rollers have to meet the high hygiene requirements in this industry and withstand washing processes with chemicals and hot water under high pressure.
- Drive systems with geared motors, such as drum motors represent a potential source of contamination in food processing.
- Conveyor rollers, in particular drum motors, for use in the Food processing must therefore be designed and processed in such a way that the risk of contamination is reduced.
- there is often a demand for low-vibration drives in food processing especially in the area of weighing units, which is why dynamically balanced drum motors are often used.
- conveyor rollers, in particular drum motors should be economical and efficient.
- a conveyor roller for conveyor systems for conveying containers, pallets, piece goods and the like comprising a roller body with a roller axis, the outer circumferential surface of which represents a support surface for material to be conveyed or is wrapped around by a conveyor belt, and a head element, which an insertion section is inserted into a hollow end of the roller body, a groove being formed on an end face of the head element facing away from the insertion section for receiving at least one balancing weight.
- the invention is based on the knowledge that the balancing, in particular dynamic balancing of conveyor rollers by negative compensation, in which masses are removed by drilling, grinding or milling, can have negative effects on process safety and reliability with regard to food safety. because bacterial nests prefer to accumulate in such processed areas.
- the term balancing refers to reducing or eliminating an imbalance and can be done statically or dynamically.
- the compensation required for this is usually done negatively in the case of existing conveyor rollers by removing the material of the head element in the form of bores, notches or flat. This creates cavities and it there is a risk of partial through-holes during machining during balancing, which can have a negative effect, since they produce a connection — often not desired — to the interior of the roller body, for example by a drive unit being arranged, to the environment.
- the conveyor roller described here now provides a groove on the head element designed to accommodate at least one balancing weight. This makes it possible to positively balance the conveyor roller by arranging at least one balancing weight in the groove.
- the at least one balancing weight is applied, for example by welding, gluing, clamping or screwing.
- the conveyor roller described here has the advantage that no undesired passages from the environment to the inside of the roller body can occur in the balancing process by removing material. Rather, the groove in the head element can be controlled and introduced reliably, since this groove can be of the same design for all conveyor rollers and does not depend on the imbalance of an individual conveyor roller.
