Arrangement in the case of a

machine for high footwear ■ f

The invention relates to an arrangement in a lace lasting machine for high footwear, in which the last with the The insole and the upper leather are held upright by a heel holder during the flexing and pinching process and then collapse into the heel holder by bending over the heel holder the tree below is released.

Known lasting machines of the aforementioned type for low footwear have a gehauseforxaigen substructure with a back inclined to the i operator top, which carries in the upper part of the VaIk- and lasting assembly, while slightly deeper seated on a generally tunnel-like console, a pneumatically or hydraulically actuated heel holder, under which the listed shoe slides down after being released by the heel holder at the end of the flexing and lasting process, while the operator introduces a new shoe last with insole and upper leather into the shoe and lasting device. As long as the upper part of the shoe has only a small height corresponding to the usual low shoes, the shoe does not cause any difficulties to fall and slide under the heel holder. For high footwear, especially boots, however, the heel holder must be positioned so high above the top of the substructure.

arranges or the top of the substructure be led down so deep that the operator when grasping the slipped down shoe would have to bend down accordingly, what v.'eder assignable is still guaranteed fatigue-free work.

The object of the invention is therefore to provide an arrangement that these pass into the handle portion at the same time a new shoe onset in the fulling and lasting assembly operator without obstructing the shared by Persenhalter shoe IABT ₁ without having to perform this particular tiring movements xuß. According to the invention, this object is achieved in that the support part of the heel holder is designed so that it can be moved laterally when stooping and can be swiveled in the opposite direction against the listed shoe. As a result, the shoe is positively pushed to the side after it has been processed in the machine and, in an advantageous further development of the invention, it can fall into a shoe holder which is arranged below the heel holder and offset to the side and which is inclined towards the operator and holds the shoe thus can slide directly into the grip area of the operator.

A preferred embodiment of the invention is characterized by an on the movable part of a known Bückühr- * " cylinder for the heel support transversely arranged slide guide for a lersenstützenträgar au3, on which de? Supports part of the Heel holder is pivotable, whereby to the side Moving the heel support carrier and pivoting the Support part further power cylinders are provided. The power cylinders are for the lateral advancement of the heel support ^ - carrier and the pivoting of the support parts expediently parallel and at the same time connectable to a compressed air line which the power cylinders simultaneously with the actuation of the ÜUickfuhr cylinder s pressure medium is supplied.

The invention is described below with reference to one in the drawing 815V3T.e-.197 = _{mt12 / 00} - T-ll-

illustrated embodiment explained in more detail. Show it:

Fig. 1 in a schematic representation of the lower part of a Spitasenzwickmaschine, of which Side seen,

FIG. 2 shows, in an enlarged representation, a plan view along line U-II in FIG. 1,

Fig. 5 shows a section along the line λ HI-III in Fig. 1 and in the same size

FIG. 4 shows a plan view similar to FIG. 2 with the Heel holder in the away position.

According to Fig. 1 has the tip-up machine on which the invention is based a housing-shaped base 1, which is at his to the control station (right) inclined top side 2 carries a flexing and lasting device 3 in a known manner, in ■ which the shoe material to be tweaked 4 ,, consisting of upper leather with inserted last and insole is held by a heel holder 5.

The heel holder 5 is attached to a top 2 of the lower

Bracket 6 fastened to the building is carried, on which a square stand 7 rises, on which a pneumatic component cylinder 1o is arranged adjustable in height by means of a clamp 8 and a toggle 9. The piston 11 of the adjusting cylinder «1o carries at its protruding end a slide guide 12 in which a transverse slide 13 is positioned between the stops 14 and. 15 is slidable. On the slide 13 is a support plate 16 with a bracket 1? attached, which carries a sliding cylinder 18, the piston rod 19 of which is supported against the slide guide 12 and when pressure medium is introduced into the cylinder 18, the support plate 16 moves to the right against the action of a pulling spring (not shown) (Fig. 4). \

A bearing block 2o is also attached to the support plate 16, on which a U-shaped lever is attached by means of a hinge pin 21 is pivoted. On one the mouth opening dee U-shaped Lever 22 between its legs by setting pivot axis 23 is pendulum-like νerschwenkbar «in the support part 24 mounted with a support plate 25 protruding on one side, which is suitably made of flexible plastic. A pivot cylinder articulated at the right end of the support plate 14

26 detected with its piston rod extended in the rest position

27 causes a second lever arm 28 of the U-shaped lever 22 and * when it is actuated, during which the piston rod is retracted into the pivot cylinder 26, a pivoting action of the lever 22 with the support part 24 and the support plate 25

On the console 6, seen from the operator's station, there is also a shoe collecting container 29 to the left of the heel holder 5 attached, which falls according to the inclination of the top 2 of the machine base towards the operator and that in it sliding down shoe material into the immediate grip area the operator can get.

To actuate the power cylinders 18 and 26, a device shown in FIG. schematically illustrated 4/2-way valve 3o, on one of which Output 31 the right end of the shift cylinder 18 and the left end of the swivel cylinder 26 are connected in parallel to each other, while the second output line - 32 - of the 4 / 2- "" Directional valve 3o only to the right end of the swivel cylinder 26 leads. In the rest position of the 4/2-way valve 3o shown in FIG. 3, the right end of the pivot cylinder 26 is at a Pressure medium line 33 is connected and holds the U-shaped lever 22 in contact with the bearing block 2o. Are at the same time the left end of the pivot cylinder »26 and the displacement cylinder 18 are vented via a throttle 34, whereby the slide 13 under the effect / tnicJat depicted) return spring in attachment his. ^ beat 15 is held against the slide guide 12 (Fig. 2 and 3> ..— In this position the heel holder is with the support part 24 and the support plate 25 from the adjusting cylinder

in the known manner against a shoe inserted into the vaIk and lasting device 3 and holds it firmly in the machine during processing; 2-way valve 3o switched to the left * bit with reference to Fig. 3 and now lets the pressure medium present in the line 33 reach the right end of the displacement cylinder * 18 and the left end of the swivel cylinder 26. If the question plate 16 with the parts it carries moves to the right, while the U-shaped he "bel 22 with the Stueta-.teil 24 and the support plate 25 is pivoted to the left and the shared shoe to the left ejects (Pig. 4) so that it λ falls in / öchuhduffangbehälter 29 and slides down in this to the operator. While the “U-shaped lever 22 is pivoted out, the right end of the pivot cylinder 26 is vented via a further throttle 35.

The actuation of the 4/2-way valve 3o is only of short duration. As well as this valve under the action of a huck part spring 36 again assumes its right position with reference to Fig. 3, will "" * "' the support plate 16 shifted to the left again and the tJ-shaped Lever 22 back to the Pig position. 2 and 3 pivoted back, and the heel holder can with the help of the adjusting cylinder 1o can be advanced against a new shoe that has meanwhile been inserted into the fulling and weighing device 3, while the operating f person removes the processed shoe from the collecting container 29.

The adjusting cylinder 1o as well as the shifting cylinder 18 and the pivoting cylinder 26 can be actuated pneumatically or hydraulically. Instead, electromagnetic actuation is also conceivable. The arrangement according to the invention can also be reversed, so that the shoe storage container is arranged on the right-TO * heel holder and the support plate 16_JudJa # tafclgwae- aea displacement cylinder 18 is moved to the left, while the U-shaped lever 22 with the support part 24 and the support plate 25 is pivoted to the right.
