Shoe bottom - roughening machine

The invention relates to a shoe floor cleaning machine, with at least one of the lasts with footwear pinched on by retaining bolts and adjustable toe bearings receiving slide, and on both sides next to and above the slide guideway each with one in the work area inwardly rotating roughening brush, which sits on a substantially horizontal pivot arm, which over a common cam control with adjustment elements is operated according to the shoe size so that the relevant roughening brush follows the side edge of the footwear adjacent to it, which with the last is moved past the roughening brush on the carriage.

Such a machine is known from the Offenlogmigsschrift 1 4 ^ 3 ί- »9 *> · Dieee Masyhine but hardly brings a keel gate and acceleration of the work, compared with the conventional roughening, whereby the worker the bottom of the shoe i: tit the hand i-jegen the roughening tool fUIirt. The previously obtained machine must always be set up again by exchanging and adjusting the control cam for the roughening brushes, if only a single piece of footwear is to be roughened with a different shape than the previous workpiece.

This results in unforeseen work breaks.

ψ Forner happens in the known machine, the very critical .Einhaltung the right Aufrauhtiefe in that a reasonably appropriate contact force of AufrauhbUrsten is adjusted prior to the operation after Filled and the worker then a carriage with the set contributed footwear or passes twice under the brushes with such Speed that just the right roughening depth is achieved, a difficult axis that can only be carried out by hand and with a great deal of experience. Depends on the roughness in the respective material.

^ But real series production requires that the Duration of work cycle and arboita just as always ^ can be set and adapted to the cycle times of the voi · - unci subordinate boeworking machines.

This task is performed in a machine of the Gattimi mentioned above; Ex-findungsgomäö solved by the application of eirtex ¹ three-dimensional rotatably mounted squat, similar to a truncated pyramid, whereby the associated scrolls, each acting on a swivel arm, are mounted in a height-adjustable manner opposite this and this bearing in the movement area of a stop ILögs ,, vo Loh.-: .r adjustable in elrit at the bottom of the bchlifcton: r Kulisae

In the case of a machine, this task becomes the one mentioned at the beginning Genus according to the invention solved by the use of a three-dimensional rotatably mounted squat, similar to a. I truncated pyramid, wherein the associated scanning rollers each acting on a swivel arm are adjustable in height relative to this are stored and this storage is in the path of movement of a stop which is adjustable at the bottom of the slide is mounted in a backdrop, which is coupled to the adjustable point bearing along the slide.

Since when fixing the footwear that is pinched on the last in the sled, its toe bearing against the lace is anyway is pushed, this necessarily results in the Presetting of the correct scanning height of the space cam for the length of the respective footwear and last, accordingly the shoe size to be processed. Without additional setup work, the inventive Machine shoes of different sizes raech one after the other to be edited.

The production of the space cam is made much easier if, in a further development of the invention, it consists of an upper and a lower disc and a roller for each scanning roller that bridges both disc edges as a surface line in the scanning area with intermediate rims. In this case, each intermediate roller can be mounted exchangeably for a locking tool, and the disks can sit interchangeably on their drive shaft. However, in order for a shoe model to be different from one another ₍ ^r eometrically similar

Making the right logs becomes whole simply the first roughening process is controlled by hand, with the still full discs with the instead of the intermediate roller The tool used must be marked and then processed according to the marking line.

Each roughening brush is advantageously coupled to the scanning roller on the respective other side of the slide guide via a cross member engaging its pivoting thread. Since the brush rotates inwards on the workpiece to keep the pinch rim tight, it is pressed outwards during this work, i.e. against the opposite control surface of the Rauron cam. This trick saves a pressure spring, which would do violence to the control linkage carrying the follower roller.

A further increase in the performance of the machine results from the fact that the center bearing and the slide end each carry a driver, which interact with corresponding limit switches in the slide track, do a · - in the Machine associated ^ known glass ribbon before roughening against the toe and / or heel of the footwear to be set so that the larger folds that are possible there are ground off in a known manner.

In order to make the work cycle independent of the material of the respective workpiece, in a further development of the invention adjustable feeler fingers are provided next to the guide brushes .be to limit the roughness depth, whereby the

the touching finger first touching the footwear passing through is preferably in the extension of the pivot axis, which is perpendicular to the tool axis of rotation. Me adjusting force is due to the weight, especially the tiltable Swivel arms and roughening brushes are given while the throughput time of the carriage under the brushes complies with the work cycle can be adapted to the upstream or downstream machines and is still the right one in every case thanks to the feeler finger The surface roughness is limited.

A particularly extensive automation and acceleration can be achieved with the machine according to the invention achieve that several carriages are coupled via an endless conveyor chain and a toothed ratchet catch for fixation the height adjustment for the lateral scanning rollers is provided, as well as a limit switch at the end of the movement path the carriage on the carriage guide, which cancels the locking «This reverses the bearing of the follower rollers back to the starting position, so that the full height adjustment range of the follower rollers when the next one enters Sled is available.

Automatic unlocking, for example by means of a limit switch behind the working position of the carriage, can be provided to the last with the respectively roughened and glazed Shoes on a conveyor belt to the next processing machine throw off.
