SCRATCH FRAMEWORK

Technical field

Bie Erfendung is concerned with a scratching machine for textile flat geoilce with at most one driven reel, with several, each with at least one rougher roller equipped with different types of rollers, as well as rotatable and lockable receiving devices being stored in the side windows of the reel. With a scraper machine for textile mushrooms, the speed of the difference between the textile fabric to be smoked and the roughening rollers roughened the surface of the textile fabric (rough effect) and thus, in particular, increased heat retention and a woolly, fluffy feel. To achieve roughening effects, roughing rolls of the same type of roll (counter-coarse roughing rolls or line-roughing rolls) or roughing rolls of different types of rolls (counter-stroking and line-roughing rolls in the same or different ratios to one another) are used. It is also possible to use different scratching strokes for the roughing rollers. State of the art

A scraper roughening machine with a plurality of pick-up devices, which are mounted in the side windows of the tampour and have a revolver-shaped design, has already been proposed (German patent specification No. 401 721). Each recording device is equipped with several roughening elements such that only one roughening element of each recording device is in the working position and that the textile fabric is first roughened with a blunt and then, in accordance with the progressing process, with a sharper scratch fitting.

By means of a corresponding pinion gear drive which is connected to the receiving devices, it is only possible to adjust aiie receiving devices together so that after the adjustment the textile fabric can be roughened again first with a blunt and then, according to the progressing operation, with a sharper scratch fitting.

Presentation of the invention

The invention seeks to remedy this. The invention is based on the disclosure of creating a scraper roughening machine in which the ratio of those in the working position by at least one unlocking, adjusting and locking device

Roughing rolls of one type of roll can be changed to roughing rolls of another type of roll.

This object is achieved by the features of the characterizing part of the first claim, namely that - adjusting device

Gesteuert has a lifting device which can be actuated in a controlled manner,

╌ is articulated to a segment carrier which is movable by the lifting device between an initial position and a recording device to be rotated at a defined angle and

Segment the active position of the segment carrier rests against a rud fixedly arranged on the receiving device to be rotated,

- The adjusting device is assigned an unlocking device

╌ has a further controllable lifting device,

╌ on which an unlocking segment which is movable by the further lifting device between an initial position and an unlocking of the active position which is to be rotated at a defined angle is anchored and

╌ aas the unlocking segment in its operative position on a locking device arranged on the recording device to be rotated prior to rotating the relevant recording device causing the unlocking.

Further features of the invention include the first

Claim following claims.

The advantages achieved by the invention are essentially to be seen in the fact that the ratio of the working Positioning roller rollers of the one to the other roller type can be changed - there is also such a reason to be understood, where only one roller type can be found in the working position - and other roughening effects can thereby be achieved. It is also essential that the surface of the textiles can remain on the Tamdour while changing the roughness of the roughness rollers, which are in the working position, so that relatively long changeover times can be avoided.

The scratching machine has, among other things, a driven drum stored in a machine frame 1 which is not shown. Essentially mener recording devices 1, which are mounted peering ends in bearing blocks 3 arranged on the pad sheaths 2, are associated with this drum. For the sake of clarity, FIG. 1 shows only one reel spool 2. Each pick-up device 1 is provided with two types of brush rollers 4, in accordance with the exemplary embodiment with two counter-brush roller 4.1 - also referred to below as 3 - and a line brush roller 4.2 - also referred to as 8 below - Equipped, where the roughening rollers 4 located on the pitch circle 2.1 are found in the working position. For reasons of clarity, the corresponding reference numerals were used only for two pickup devices 1 and the types of brush rollers 4 stored therein. The brush rollers 4 are supported at both ends in the pickup devices 1, preferably only the brush rollers 4 in the working position being driven.

The receiving devices 1 mounted in the reel disks 2 are, as will be described below, locked in their initial position and unlocked, then correspond to the division of the roughening rollers 4 in the receiving device 1 appropriate angle and then locked again in our new cage. This makes it possible to change the roughness of the begenstrichraunwalzen 4.1 in the working position to the Gerichraunwalzen 4.2. 5o, the following variants of the riveting of the roughing rollers 4 located in the division of labor are preferably possible:

The scratching machine also includes an input traction roller 5 and an output traction roller 6, both of which are mounted in the machine frame and with which textile textile structures 7 running over the drum are transported and at the same time are held under a certain tension. Other elements belonging to the scratching machine, such as drive, entrance and exit of the scratching machine, cleaning rollers, were also not shown for reasons of clarity. the ratio of those in work position To unlock roller rollers 4 of one roller type to the other roller type, an unlocking device, a locking device and a locking device, as shown in FIGS. 2 and 3, are provided. 2 shows the unlocking device in its operative position, ie in a position already initiated in the unlocking process for a defined receiving device 1.

The unlocking device has a first working cylinder 9, which is preferably pivotably mounted in a receptacle 8 provided in the maserun frame, and a ramp element 10 which is angled on the piston rod 9.1 of this working cylinder 9 and is pivotably mounted in a bearing point 11 which is also preferably arranged in the machine frame. The side of the run-up element 10 that points toward the spool disk 2 is designed as a run-up curve 10.1, on which a roller 13 mounted on an unlocking lever 12 rolls when the relevant receiving device 1 is unlocked. The unlocking lever 12 is mounted in a receptacle 14, which is preferably attached to the bearing part 3, and articulated by a pulling element 15 on a locking pin 16.

As is also apparent from FIGS. 2 and 3, the adjusting device used for burning via the receiving device 1 concerned has a second working cylinder 18 mounted in a bearing 17 arranged in the machine frame. On the piston rod 18.1 of this second working cylinder 18 is a segment carrier 20 mounted in a bearing 19 arranged in the machine frame. This segment carrier 20 is equipped with a friction segment 20.1, which is connected to a friction disk 21, which is preferably fixedly arranged on a bearing journal of the receiving device 1 in the event of the receiving device 1 drenching.

The locking device has a locking disk 22 with recesses 22.1 which is firmly connected to the receiving device 1. The locking pin 16, which is loaded by a compression spring 23 and articulated by a tension element 15 on the unlocking mist 12, projects into one of the existing cutouts 22. 1, thereby fixing the position of the recording device 1.

2 and 3, only one unlocking device, one adjusting device and one locking device are shown. The unlocking and adjusting device are mounted at a defined point in the machine linkage and in the area of the one reel 2 so that the unlocking and adjusting device in the event of a change in the ratio of the rough rollers 4 in the ardeltsposition of one type of roller to that of the other roller type the defined receiving device 1 acts. A second unlocking and adjusting device is also mounted on a defined position in the machine linkage and in the area of the other spool disk 2 so that it is the same bring about an adjustment (unlocking, draining around a defined angle and locking again) of the relevant receiving device 1 acting together with the other unlocking and adjusting device.

However, it is also possible to store a further pair of the unlocking and adjusting device at a further defined location in the machine frame 1 in order to be able to adjust a further recording device 1.

The locking devices are at both ends in front of all recording devices 1.

The unlocking, adjusting and locking device according to the invention works as follows:

The sequence of the changeover of a recording device 1 is predetermined by a programmable logic controller 25. To detect the position of the drum, an absolute angle sensor 26, which is connected to the stored-program controller 25, is assigned to it. It is thus possible to exactly identify the position of each receiving device 1 with respect to the absolute dren angle α aer spool discs 2 and thus the spool. Within the programmable logic controller 25, each recording device 1 is assigned a reference quantity, in the case of games a number. Equal to this is the relationship between the counter-coarse rollers 4.1 and the line-brush rollers 4.2, and thus the position of each pick-up device device 1 stored in the storable programmable controller 25.

When changing the ratio of the scraper roller 4.1 to the streak roller 4.2, the operator selects the desired ratio of the streak roller 4.1 to the streak roller 4.2, enters this data into the programmable logic controller 25 and starts it and thus the conversion of the corresponding recording devices 1. The programmable logic controller 25 defines the pick-up devices 1 to be converted from the best-performing and the desired ratio of the cross-grained brush rollers 4.1 to the line-brush rollers 4.2. In this case, with certain pick-up devices 1, a double change and thus preferably a renewed reel rotation may be required. The solenoid valves 27, 28 for the first working cylinder 9 and the solenoid valves 29, 30 for the second working cylinder 18 are controlled directly as a function of the absolute rotation angle of the drum, the respective position of the working cylinders 9, 18 by sensors 31, 32, 33, 34 can be checked. Another sensor 35 controls the locking of this receiving device 1 after the changeover of the receiving device 1 by the locking pin 16 in connection with the locking disk 22.

In the event of a change in the ratio of the counter-streak roller 4.1 to the streak roller 4.2, the defi The first working cylinder 9 is loaded with a pressure medium by the first working cylinder 9 and starting from the starting position - this starting position corresponds to the adsolute drenwinkel α ₁ - of the recording device 1, so that the Kolden rod 9.1 and thus the Auflaufeiement 10 in the operative position shown in Fig. 2 emotional. Due to the rotary movement of the spool - this is shown in FIGS. 1 to 3 your arrow 24, and when changing the ratio of counterstretching rollers 4.1 to line-top rollers 4.2 is preferably a relatively low number of drums in front - the roller 13 rolls on the run-up curve 10. i in the first phase so that the unlocking lever 12 mounted in the receptacle 14 lifts the locking pin 16 via the pulling element 15 and the receiving device 1 is thus unlocked. When the angle of rotation α ₂ is reached, the second working cylinder 18 is pressurized with a pressure medium, so that the extending piston rod 18.1 moves the segment carrier 20 into its operative position, that is to say that the friction segment 20.1 bears against the friction disk 21. Due to the rotary movement of the drum, the friction disk 21 rolls on the friction segment 20.1 and thus rotates the recording device 1 until an angle of rotation α _{4 is reached} . When reaching the α between the Drenwirtkeln α ₂ and ₄ lying rotational angle α ₃ takes the opposite actuation of the first operating cylinder 9, so that this back its output! age, as shown in Fig. 3, occupies. When the dren angle α _{4 is reached,} the defined recording device 1 completes a rotary movement of 120 °. Thus, a recess 22.1 in front of the locking disk 22 also reaches a position in which the locking pin 16 engages in this recess 22.1 by the force of the compression spring 23. The defined recording device 1 is thus adjusted by a drenwin angle of 120 ° and locked again. At the same time, this means that a roughing roller 4 that was previously in the working position is now outside of its working position, while the roughing roller 4 located outside the working position is now on the pitch circle 2.1 and thus in the working position.

Sieichfalls the second working cylinder 18 is acted upon in the opposite direction with the pressure medium upon reaching the Drenwinkel α ₄ , so that the latter and thus the segment carrier 20 move back into their starting position.

When the drum is in the area of its third angle α ₅ , the locking of the recording device 1 rotated in front is checked by a sensor 35.

The processes relating to the unlocking angle α for unlocking, draining and locking a pick-up device are shown in FIG. 4. The processes described also run for the unlocking, adjusting and locking device assigned to the other end of the defined receiving device 1 animal facility from the same time and clock.

With the completion of the unlocking, adjusting and locking process in its entirety with a recording device 1, drum continues to grow, unless the preselected recording device 1 - labeled "n" in FIG. 4 - is in the defined, ie. n. located in the position required for unlocking, drilling and locking in relation to the unlocking, adjusting and locking devices. When this position is reached, the unlocking, draining and re-locking of the relevant receiving device 1 takes place, as has already been described and shown in FIGS. 2 to 4. This process is repeated in accordance with the inputs given by the operating programmable control 25.

The size of the angle of 30 ° shown in FIG. 4 is derived from the number of recording devices 1 stored in the drum; in the present exemplary embodiment:

360 °: 12 recording devices 1 = 30 ° / recording device.

However, it is also possible to specify a different angle, such as 60.degree., 90.degree., Etc., for the storage programmable controller 25 for the selection of the measuring devices 1 to be adjusted. If there are fifteen recording devices 1 on the drum, for example, there is an angle of 24 °, which the memory-programmed controller 25 is given as a size. The elements for control shown in FIG. 2, such as wιnκeigeoer 26, solenoid valves 27, 28, 29, 30, sensors 31, 32, 33, 34, 35, the memory-programmed control 25, are shown in FIG. 3 for reasons of clarity not shown. This also applies analogously to the identification of the receiving devices 1 located outside the unlocking, adjusting and locking area.

Industrial applicability

The solution according to the invention is used in scraping machines, as are to be used in the textile finishing industry for finishing textile fabrics 7.

The scraper roughing machine has at least one driven drum, with menrere in the side windows 2 of the drum, each equipped with at least one roughing roller 4 different types of rollers, and rotatable and lockable

Receiving devices 1 are stored.

The advantages achieved by the invention are essentially to be seen in the fact that the ratio of the roughing rollers in the working position of the one to the other roller type can be changed - this is also to be understood as meaning a ratio in which only one roller type is in the working position befinoen - and thus other roughness effects can be achieved. It is also important that the texti le surface area during the change of the Vernisshiß of the working position 1 Raunwalzen one can remain on the reel with the other type of waizen and thus relatively long changeover times can be avoided.
