Patent number: 10858777Abstract: Laundry items by way of devices are fed to mangles, for example. The laundry items by way of the corners thereof are transferred to clamps, for example spreader clamps during the feeding procedure. Tails of the laundry item that project beyond the clamping locations of the spreader clamps are usually formed herein. Said tails lead to so-called ears in particular on the front periphery of the laundry item that is tautly stretched by the spreader clamps. Said ears compromise the quality of the laundry items, specifically of mangled laundry items. The invention provides for the tails in the spreader clamps to be eliminated in that the tails are transported through the spreader clamps so far until the corners of the laundry item are still held in the spreader clamps only at the outermost corner points. The tails are effectively eliminated in that ears can no longer be formed.Type: GrantFiled: September 15, 2017Date of Patent: December 8, 2020Assignee: Herbert Kannegiesser GmbHInventors: Wilhelm Bringewatt, Thomas Klarhorst, Arthur Malikowski, Engelbert Heinz

Patent number: 10738416Abstract: The automatic sorting of laundry items requires a knowledge of all sorting criteria. One strives to read these out from data storage media attached to the laundry items. The problem is when laundry items lack data storage media, or they are not readable because they have been damaged, for example. The invention calls for deriving sorting criteria which cannot be otherwise obtained from at least one imaging recording of an imaging device, such as a 3D-camera. Such sorting criteria, which cannot be derived from the picture or recording of the 3D-camera, are derived from supplemental information which can be obtained in different ways. Thus, it is also possible to sort laundry items without data storage medium or with damaged data storage media in a fully automatic or at least largely automatic manner.Type: GrantFiled: November 13, 2018Date of Patent: August 11, 2020Assignee: Herbert Kannegiesser GmbHInventors: Engelbert Heinz, Wilhelm Bringewatt, Jürgen Sielermann, Peter Holtz

Publication number: 20200240072Abstract: A method and apparatus that makes provision for two identical folding machines to be arranged one beside the other, and for these to be operated synchronously, so that the large operating width which is necessary for ironing large laundry items, in particular transversely, is also available for folding such laundry items. If large laundry items are to be ironed, and folded, in particular transversely, this requires ironers and folding machines with an appropriately large operating width. Such large operating widths currently cannot be realized technologically in folding machines.Type: ApplicationFiled: January 23, 2020Publication date: July 30, 2020Applicant: Herbert Kannegiesser GmbHInventors: Wilhelm Bringewatt, Engelbert Heinz

Publication number: 20200224359Abstract: A method that facilitates the automatic identification of the long edge or the short edge of the item of laundry by determining the lengths or the angles of the edge areas of the item of laundry extending from a lower corner of the item of laundry. It may be derived from the determined angles or lengths of the edge areas whether the respective edge area belongs to the long edge or to the short edge of the item of laundry. With this information, a targeted transverse or longitudinal feed of rectangular items of laundry may be carried out to a downstream inserting machine. The fully automated feeding of items of laundry to, for example, an inserting machine is carried out in a targeted way with either the long edge of the item of laundry extending transversely to the feed direction or the short edge extending transversely to the feed direction.Type: ApplicationFiled: January 6, 2020Publication date: July 16, 2020Applicant: Herbert Kannegiesser GmbHInventors: Wilhelm Bringewatt, Engelbert Heinz

Publication number: 20200165768Abstract: The automatic supply of items of laundry to a feeding machine for supplying the items of laundry to a mangle requires the formation of adjacent corners of an edge of the item of laundry, which edge is to be spread upstream of the feeding machine, which hitherto has not been able to be achieved automatically with sufficient reliability. The invention brings the respective item of laundry into a U-shaped configuration before same is supplied to the feeding machine and, starting from said configuration, to stretch apart said item of laundry with a spreading device having a conveyor cascade. This reliably forms the adjacent corners of the edge, which is to be stretched out, of the item of laundry, said corners being required for automatically feeding the item of laundry into the feeding machine. A reliable automatic supply of the respective item of laundry to the feeding machine is therefore ensured.Type: ApplicationFiled: November 19, 2019Publication date: May 28, 2020Applicant: Herbert Kannegiesser GmbHInventors: Wilhelm Bringewatt, Markus Nolte, Engelbert Heinz

Publication number: 20200165771Abstract: A method that provides to partially automate the feeding of pieces of laundry to an insertion machine by steps which necessitate long distances to be traveled being performed manually. With large pieces of laundry such as, for example, tablecloths and bed sheets, for complete automation a large amount of space is required and the clamps holding corners of the pieces of laundry are required to travel long distances. To achieve this, it is provided to temporarily store the respective piece of laundry after it has been separated and before it is delivered to an insertion machine. It is furthermore provided that in a first corner of the piece of laundry is supplied or held ready by an automatic separator for an operator to manually locate the second corner of the piece of laundry. Partial automation can be achieved without the cycle time being adversely affected owing to manual handling processes.Type: ApplicationFiled: November 14, 2019Publication date: May 28, 2020Applicant: Herbert Kannegiesser GmbHInventors: Eduard Regier, Wilhelm Bringewatt, Engelbert Heinz

Patent number: 10662576Abstract: A method and device allowing the items of laundry which are to be ironed to enter the ironer gap in a manner directed downwards. For this purpose, the inlet region is preferably arranged below the outlet region. The invention ensures a disturbance-free and crease-free entry of items of laundry to be ironed into the band ironer. In the case of band ironers, the inlet region, and outlet region have to lie tightly together in order to bring about as large a wrapping angle of the ironer body by means of the ironer band as possible. This makes the inlet of items of laundry to be ironed into the ironer gap emerging from the inlet region problematic. This invention described herein provides a solution to this problem.Type: GrantFiled: June 18, 2018Date of Patent: May 26, 2020Assignee: Herbert Kannegiesser GmbHInventors: Wilhelm Bringewatt, Engelbert Heinz

Patent number: 10619283Abstract: Washed laundry that has been rinsed still contains bound acidic or basic rinsing liquid. In many cases this must be neutralized. This used to be conducted on the basis of values gained from experience, which generally resulted in only partial neutralization. Herein, sample liquid is taken continuously from the neutralization chamber (18) and, after the fine filtration of same, the pH value of the sample liquid is continuously measured by a pH value measurement device (31). In this manner a pH value control system is possible which ensures an automatic and complete neutralization of the rinse liquid still bound in the laundry after rinsing.Type: GrantFiled: April 3, 2014Date of Patent: April 14, 2020Assignee: Herbert Kannegiesser GmbHInventors: Wilhelm Bringewatt, Engelbert Heinz

Publication number: 20200056315Abstract: Methods and apparatuses that provide for laundry to be washed and rinsed in a washing device in a state in which it lies spread out on an upper strand of a belt conveyor and, directly thereafter, to be dried in a likewise spread-out state on an upper strand of a belt conveyor. During the washing, rinsing and also the drying operations, the laundry rests on the belt conveyors, which also transport the laundry through the washing device and the dryer. The items of laundry here are washed, and also rinsed, by being sprayed with jets of liquid. The procedure described provides for a compact washing and drying system and is gentler on the items of laundry.Type: ApplicationFiled: November 2, 2017Publication date: February 20, 2020Applicant: Herbert Kannegiesser GmbHInventors: Wilhelm Bringewatt, Engelbert Heinz

Publication number: 20190352840Abstract: A method and apparatus that makes provision for a length of a transverse edge of a laundry item to be spread out to be measured upstream of a spreading device, to be precise preferably from above. It is thereby possible to individually determine the length of the transverse edge for each individual laundry item before the laundry item is situated in the spreading device. The length dimension of the transverse edge determined upstream of the spreading device can then be used to move apart the spreading clamps of the spreading device in a targeted and controlled manner in order to spread out the transverse edge in as gentle a manner as possible.Type: ApplicationFiled: May 10, 2019Publication date: November 21, 2019Applicant: Herbert Kannegiesser GmbHInventors: Wilhelm Bringewatt, Engelbert Heinz

Method and apparatus for feeding items of laundry to a laundry treatment device, preferably a mangle
Patent number: 10480118Abstract: Items of laundry are fed to mangles by insertion machines, which have a spreading device with moveable spreading clips which spread out and center a front transverse edge of the item of laundry upstream of a feed conveyor. A plurality of loading stations are located upstream of the spreading device. The spreading clips retrieve an item of laundry from the loading stations, which, in the case of outer loading stations, requires long movement distances of the spreading clips, which reduces the cycle time of the insertion machine. The invention makes provision to transfer items of laundry from outer loading stations to transfer clips which move the items of laundry from the outer loading stations into the vicinity of the center of the feed conveyor, then transfer the item of laundry to the spreading clips in the center of the feed conveyor, thus reducing the travel distances of the spreading clips.Type: GrantFiled: September 26, 2017Date of Patent: November 19, 2019Assignee: Herbert Kannegiesser GmbHInventors: Wilhelm Bringewatt, Thomas Klarhorst, Arthur Malikowski, Engelbert Heinz -
Publication number: 20190345664Abstract: A method and device for supporting the isolating of pieces of laundry from a pile of laundry by means of an imaging apparatus. A further imaging apparatus serves for raising a front edge region of the piece of laundry onto the feed conveyor in an aligned manner. Furthermore, the gripping of corners or also edges, in particular the alignment thereof, can be detected by means of an imaging apparatus. The gripping and aligning of the pieces of laundry can be controlled or regulated by way of the positions and edge contours of the same which are determined by the imaging apparatuses. As a result, reliable, fully automated isolating of pieces of laundry and/or fully automated, targeted feeding of pieces of laundry to a folding machine or another such laundry subsequent handling apparatus is ensured.Type: ApplicationFiled: May 4, 2017Publication date: November 14, 2019Applicant: Herbert Kannegiesser GmbHInventors: Wilhelm Bringewatt, Jürgen Sielermann, Engelbert Heinz

Patent number: 10351991Abstract: A method and device for directly determining the region of the respective laundry item to be inserted into a clamp. In this way, it is possible to determine whether the clamp has actually been loaded with a laundry item and whether the region of the laundry item designated for this has also been properly inserted into the clamp. During the transport and the spreading out of laundry items being washed it is customary at commercial laundry establishments to hang the laundry items from clamps, which are transported further by a conveyor to various processing stations. It happens that the clamps may move away before having been loaded with the laundry item. This results in operational disruptions in most cases.Type: GrantFiled: January 5, 2018Date of Patent: July 16, 2019Assignee: Herbert Kannegiesser GmbHInventors: Wilhelm Bringewatt, Engelbert Heinz
