Description

The The invention relates to a method and a system for generating Upholstery elements in which a padding material web from a roll is unrolled and supplied to a cushioning element machine becomes.

A corresponding pad element machine is for example from the DE 698 31 450 T2 known. With such a pad element machine padding elements are typically prepared by a paper web is on the one hand crumpled laterally to form a three-dimensional, resilient pad and on the other hand, the paper web is cut into strips, so that the padding elements each have a predetermined length. Such cushion-like padding elements on the one hand have good cushioning properties, since they are relatively easily deformable. On the other hand, depending on the requirements, they can also be packed more tightly and thus securely cushion sensitive objects in packaging. Due to their relatively low density, the transport costs for appropriately packaged goods are relatively low. Such packages have also proven to be cheap because they are biodegradable, recyclable and renewable and therefore quite environmentally friendly.

machinery for the production of upholstered elements usually have machine-specific recordings on, in which the respective padding material is inserted before it is processed. In a roll feed are appropriate Receptacles, usually metal rods, provided on which the Roller is inserted in the upholstery element machine, so that the material web is unrolled and fed to the respective processing plant can be, in which the cushion element is formed.

at Such commercial upholstered element machines are Paper rolls used that are manually manageable, that is transportable and can be inserted into the upholstery element machine. The paper rolls are therefore depending on the amount and processing speed in the generation of cushioning elements used up relatively quickly and have to be renewed. On top of that, for the respective machines usually needed special paper rolls whose cores in terms of width and diameter to the respective Machine are adapted. The paper roll sits loosely on the receiving element and the paper web is passed through an in-machine Drive deducted, at the same time the deformation of the paper web causes.

From the US 5,472,153 A An arrangement for feeding a paper web from a roll to a printing device is known. The paper web is thereby removed from the roll by a motor, a loop is formed, the loop is scanned and the motor, depending on the loop size, is driven in such a way that a continuous feed of the paper web to the printing device can take place. A similar rollfeed arrangement is known from US 4,848,634 A known. From the EP 1 085 451 A2 a printing system is known in which a paper web is fed to a printing device.

The previously mentioned publications are hereby by Reference is included in the description.

It It is an object of the invention to provide a method and a system for the production of upholstery elements with which the supply of a cushion material web from a roll to a deformation of the cushioning material web effecting the upholstery forming work reliably and easy to handle is possible.

to Solution to this problem is inventively a Upholstery material web unrolled from a roll and a pad element machine fed, with the unwinding with a regulated drive takes place and the cushion elements in the upholstery element machine the padding material web are formed in sections.

According to the invention was Recognized that by using a controlled drive when unrolling the cushion material web a secure continuous feed is possible. Furthermore, it was recognized that by use a controlled drive also very large pad material web rolls are veritable. For example, it can be paper rolls be processed, which are several hundred kilograms, more than fifty inches wide and one diameter of more than fifty centimeters. With such a big one Paper rolls can use very large quantities of upholstery elements getting produced. The upholstery material webs need accordingly be changed much less often than in conventional Upholstery element systems. Through the electronically controlled unwinding process the supply of the cushioning material web to the upholstery element machine takes place very efficient.

In a preferred embodiment of the invention, a loop of the cushion material web is generated for driving control, the loop automatically scanned, in particular the position of the lower end and used the scanning signals generated thereby to drive a drive motor for the rolling motion. In particular, the length of the loop can be scanned and accelerated when falling below a predetermined lower limit for the loop length of the engine, in particular be set in motion and when exceeding a predetermined upper limit for the loop length of the drive motor is delayed, in particular stopped. The scanning signals can be generated with at least one optical and / or one acoustic sensor arrangement. For this purpose, in particular a light barrier sensor or an ultrasonic sensor can be used.

By the scanning of the loop can be the loop position and thus the paper supply for the supply of the paper web held to the cushioning element machine within predetermined limits. In particular, the boundaries can be independent of the roll diameter are maintained when the peripheral speed the role changes because z. B. the drive over a motor that acts on the roll core.

The Drive control can in particular via a torque-controlled Drive motor done. The drive motor is in particular of a controlled electrical control that processes the Abtastsignale.

To the Driving the roller, the drive motor on at least one drive element act, which rests against the peripheral surface of the roller and / or on which the roller rests and causes its rolling movement. This Drive element may comprise, for example, one or more rollers, a mandrel inserted into the core of the roll or also flexible bands that drive the roller by friction.

The unrolled cushioning material web is preferably the upholstery element machine over at least one guide element fed in such a way that the padding material web centric in a Bahnverarbeitungswerk is introduced, in which the padding material web sections is molded in upholstery elements. The upholstery element machine crumpled and cuts the cushioning materials in particular such that the upholstery elements as crumpled, for example oblong shaped elements are output. The forms can thereby vary arbitrarily, for example as a pillow shape, as a spiral or as a ball. The cushion material web is preferably of paper, in particular of printed paper.

According to one second aspect of the invention, in common or independent executed by the aforementioned aspects of the invention can be, is a web-shaped for the production of upholstery elements Record carrier printed in a printing device, the printed record carrier rolled up on a roll and the record carrier is unrolled from the roll again and a cushioning element machine for producing the cushioning elements fed.

According to this Aspect of the invention has been recognized that cushioning element machines advantageously equipped with printed record carriers can be used to produce upholstery elements. From the Knowledge results in a number of interesting economic Advantages. A salient advantage of the invention is then achieved when printing in the course of tests of the printing device and / or testing other devices or processes for informational output takes place during development, manufacturing and / or installation these devices or process. For example, fall Testing for High Performance Digital Printing Equipment, from a few tens to well over a thousand pages per minute print, as part of the development and testing processes several hundred thousand Print pages, which conventionally disposed of as waste paper Need to become. With the present invention, this Disposal process omitted and instead the in the printing process anyway on rolls available printed paper webs advantageous be used for the production of upholstery elements. This will be considerable resources both in papermaking and in Saves the processing of waste paper. For the operator the upholstery element machine can in particular be a cost saving result in the fact that he no longer needs new paper, but cheaper, used and printed test paper.

The Processing can preferably be carried out so that the from Print device output in a reel is rolled up, the role removed from there and transported to a unrolling device, is inserted there and then supplied to the pad member machine.

A Paper pad element machine that produces padding elements from paper, is supplied with a paper web by means of a printed roll a regulated drive is unrolled. With the scheme can can be achieved that the paper feed exactly as much Paper supplies as for the upholstery production is needed. This is especially in a discontinuous Operation of advantage. The printed paper roll can be used in a test procedure for Pressure devices are generated. This can be environmentally friendly the paper printed in the test is sent for reuse and save new paper.

In a further advantageous embodiment of this aspect of the invention, document information is used as printing information, in particular images and / or logos, which are used for a later packaging process in which the Upholstery elements are used, are usable. As a result, for example, targeted company or product information can be printed for the manufacturer, processor or consignor of the packed goods packed with the upholstery elements. In a corresponding system, the printing device is then connected to a data source which provides information, in particular test images, for a test of the printing device and / or information output processes which, during the development of the printing device or the information output processes, are transmitted to the printing device so that they are printed become.

It demonstrate:

1 : A flow chart for the creation of upholstery elements from a printed record carrier web and

2 : Details of feeding a padding material web to a padding machine.

In 1 Systematically a system and a process for the production of padding elements made of paper are shown. The upholstery elements 14 become from a paper web 6 generated in a pressure device 1 is printed. The printing process takes place in a printing center or at a pressure equipment manufacturer in the course of a test process for the printing device. The data to be printed is transmitted via the data connection 18 from a print server 2 to a character generator 5 which exposes, for example, with LED lines or with a laser scanner on a photoconductor drum and according to the well-known electrophotographic printing process on the paper web 6 transfer-printed.

Of course, the printing device has further components, such as a fixing device, which are not shown in the schematic diagram. This is again at this point on the EP 1 085 451 A2 verwiessen and there especially on the 1 and 5 with the corresponding descriptions.

Instead of An electrophotographic printing device can also be a digital printing device be used that works on a different pressure principle, for example an inkjet printing device.

The paper web 6 becomes the printing device 1 from a roll of paper fed into a dispenser 7 is inserted. The printed paper web 6 will turn on a roll of paper 9 in a reel 8th is inserted, rolled up in a reeling direction B. Inside the pressure device 1 becomes the paper web 6 along a paper transport direction A through the printing unit 3 emotional.

The print server 2 can as input data via a data connection 17 Data from a user computer 16 receive. The data connection can be made online via a network or offline with a data medium. The print server 2 and the printing device 1 may be located in particular in a test printing center and the user computer in a sometimes far away logistics and packaging center. On the user computer 16 In particular, it is possible to generate data for printing which are relevant for a later-described packaging process, for example names, product information or logos of the manufacturers, packagers or packaged goods forwarding agents.

After the printing process becomes the printed paper roll 9 in a transport process C to a dispenser 10 spent. This is preferably done by the paper roll 9 from the reel 8th taken, transported with a suitable vehicle to the more or less distant packaging location and there in the dispenser 10 is inserted. But it is just as possible to provide a combined up / unwinding, which is mobile and the paper roll 9 to transport together with the up / unwinding device. The transport can be done within a production or test site, for example, from a test room for printing equipment to a packaging room for printing equipment and device components. There will be the dispenser 10 set up and the paper web 6 from the roll of paper 9 unrolled in the unwinding direction D and a pad element machine, here a paper crumbler, supplied in the paper web 6 is processed into upholstery elements and the upholstery elements 14 in a dolly 12 be stored. The upholstery elements 14 can just as well be fed to another process, for example directly to a packaging process. The paper crumpling machine can do this 11 be integrated directly into a larger packaging system, are provided in the other packaging machines. From the paper crumpling machine 11 are in 1 only schematically a crumple 31 shown in the paper web 6 is deformed into a three-dimensional creased upholstery, as well as a knife 32 , with which the deformed paper web sections in upholstery elements 14 be cut with a given, in particular adjustable, length. With the trolley 12 become the upholstery elements 14 transported to a packing station (Transport F) and there in packaging 13 introduced for padding of goods. In 1 is a packaged example, for example, a sensitive fixing roller 15 shown for electrophotographic printers.

2 shows the dispenser 10 and the paper crunching machine 11 more in detail. The paper roll 9 is on a frame 22 of the unwind 10 mounted, with the roll core 21 the roll of paper 9 on a drive pin 20 of the unwind 10 rests, with a drive motor 19 is drivable, so that the paper roll 9 in the unwinding direction D rotates. For controlling the drive motor 19 is a motor control 27 provided on the basis of sensor signals of an upper ultrasonic sensor 23 and a lower ultrasonic sensor 24 the drive motor 19 controls. The sensors 23 . 24 feel the bottom edge 33 the paper loop 25 the paper web 6 from (and therefore the length of the loop), due to the gravity of the paper web 6 formed. The loop 25 forms in a horizontal loop area 34 because of the paper web 6 loosely over the guide elements 26a . 26b of the unwind 10 running. The rolling movement can by means of the controller 27 be regulated so that the loop 25 always in the vertical loop area 35 located.

Regarding further possible details of the retractor 8th and Abrollers 10 will be at this point again on the US 4,848,634 and the US 5,472,153 directed.

The paper web 6 becomes the paper crunching machine 11 via a lower input roller 28 and other guide rollers 29a . 29b fed. With a funnel 30 becomes the paper web 6 continue to be aligned so that they are centered in the crumple 31 enters. The edges of the funnel are so rounded that a tearing of the paper web 6 is avoided. This is still an additional guide element 26c intended. In the funnel 30 If desired, the paper web can already be tapered on one or more axes so that it is preformed, in particular pre-crumpled, before it enters the crumple 31 passes, which is formed for example by a plurality of meshing, toothed and driven wheels. After passing through the crumb 31 is the paper web with a knife 32 , which is rotatable in the direction of E, cut into predetermined lengths.

With regard to other possible details of upholstery element machines is at this point again on the DE 698 31 450 T2 directed.

It embodiments of the invention have been described. It is clear that instead of the components described others Components can be used. For example, instead of the Knüllprinzip described for the upholstery elements also another processing of the paper web for the production of Padding elements can be used, for example, a plant for the production of paper shreds. Furthermore, instead of the described ultrasonic sensors of the unwinder also other Suitable sensors, such as retro-reflective sensors or transmitted light barriers be used. Finally, it is also clear that the paper crumpling machine not only has the described mechanical components, but For their part, also suitable for their tasks electro nic Control. This control can also be used with the control of the unwinder be combined to further optimize the overall process, z. B. to even higher processing speeds reach when the dispenser is not only on the signals of the loop sensor assembly can resort to, but in addition to any control signals the pad element machine, z. B. on a "stop" signal.

The Upholstery element machine may be in addition to that described Coupling with a regulated driven dispenser also a conventional one Recording for paper rolls without drive or with one Have unregulated drive, especially for smaller Paper rolls that are easy to handle manually. An attached there Drive can z. B. operable with a foot switch be to give an operator the possibility of paper to be supplied automatically as needed.

When Padding material is preferably paper, but it can also consist of other materials, or include these, for example Plastics, in particular webs of air-cushion plastics.
