Definitions
- the invention relates to a device for feeding bundles of bristles into receiving openings of target plates, having at least one sliding drive and at least one sliding pin for pushing a bundle of bristles into a receiving opening of a target plate.
- the invention also relates to a brush manufacturing machine with such a device and a method for operating a device for feeding bundles of bristles into receiving openings of target plates with at least one sliding drive and at least one sliding pin for pushing a bundle of bristles into a receiving opening of a target plate.
- bundles of bristles can be inserted individually or in groups into receiving openings of a target plate.
- the target plates equipped with bristle bundles can serve as auxiliary means with which the bristle bundles can be fed to further processing steps that are to be carried out to produce the brush.
- the object of the invention is to provide a device, a brush manufacturing machine and a method of the type mentioned at the outset, with which the manufacture of brushes can be simplified.
- a device for feeding bundles of bristles into receiving openings of target plates with at least one sliding drive and at least one sliding pin for pushing a bundle of bristles into a receiving opening of a target plate is proposed, which is characterized in that the device has at least one Has a sensor with which a force transmitted from the sliding drive to the at least one sliding pin can be determined at least indirectly.
- the at least one sensor can be a force sensor and/or a pressure sensor, for example.
- the at least one sensor can be a piezo force transducer. Such a sensor is set up for the precise measurement of tensile and compressive forces with the highest resolution.
- a device for feeding bundles of bristles which enables the force transmitted from the sliding drive to the sliding pin to be monitored.
- the force is a process parameter when operating such a device, which allows conclusions to be drawn about various factors that can influence the process quality.
- the force to be applied during operation of the device can, for example, allow conclusions to be drawn about the condition of the device, about the bristle bundles to be pushed in with the device and/or about the pushing-in process. It is thus possible to influence a manufacturing process of brushes in a targeted manner as a function of the force determined with the at least one sensor.
- an increased force can be detected at the beginning of the travel of the at least one sliding pin, this can indicate that the device is dirty and that cleaning is required. It is also possible that in this case the at least one sliding pin ft and/or one Guide for the slide pin are dirty and/or worn.
- An increased force in a rear or last area of the adjustment path can indicate, for example, that the inserted bundle of bristles is too long and is therefore already in contact with a stop of the device.
- An increase in the force detected in a rear or last area of the adjustment path which goes beyond a normal increase, can thus be taken as an opportunity to control an upstream process for producing the bristle bundles and, if necessary, to adjust the length of the bristle bundles to be inserted.

Even when idling, i.e. when no bundles of bristles are pushed into the target plate with the aid of the device, but the push pin is moved without bundles of bristles, the force that can be measured can indicate that the device is dirty and/or the device is worn.
- an increase in the force can be determined at the beginning of the positioning/sliding path of the sliding pin, this can indicate that a cutting device with which the bristle bundles are separated has become blunt.

It can also be useful to monitor the force when the at least one sliding pin of the device is pulled back with the aid of the at least one sensor.
