DE486158C - Machine for centering and fastening the heel when shoes are inserted - Google Patents

Description

The invention relates to a machine of the type used for centering and securing the heel when the footwear is inserted, in which a centering rod, tool and fastening means are felt through a hole in the last. The invention enables a precise setting of the heel and automatically compensates for the difference in the different thicknesses of insole, last and heel height, so that the tools can work immediately in the correct setting for the footwear and the fasteners achieve their exact position in the scabbard; The machine has 'all-round' accessibility for mounting the shoes and attaching the individual tools, as well as a good overview so that the work can be carried out quickly and the efficiency is increased. According to the invention, the machine has a pivotable support for the footwear with a last and heel; the axis of rotation of this carrier lies outside of the Zentriei pin; the latter and the tools themselves are stored in the stationary machine frame next to each other on an arc of a circle, which is described by the hole in the strip when the carrier is pivoted. In otherwise well-known machines of the present type, the workpiece carrier has the possibility of a pivoting movement in the horizontal plane about a vertical axis, but the relative position of this axis of rotation and the individual tools is significantly different, whereby the advantages of the subject invention ¹ are lost.

'To explain the invention, an embodiment is shown on the drawing, namely shows:

Fig. Ι a front view with a partial section through the upper bearing eye,

Fig. 2 is a side view,

Fig. 3 is a plan view of part of the machine frame, Fig. 4 the associated front view and

Fig. 5 shows the corresponding side view.

After the heel b is loosely put on, the inserted shoe is clamped in the bracket ei by the pressure spindle e in such a way that the hole in the last is exactly above the hole in the support tP- .

The bracket d can be rotated about the bracket k. A centering sleeve q, which carries stops / 7, is vertically displaceable and resiliently mounted in the eye g · ^{1 of} the machine frame g. This centering bush has a through bore q ¹ for the passage of a centering rod / deir can be brought by a bayonet / ¹ occasionally in fixed connection with the Zentrierbüehse q. Furthermore, the eye g ^{1 has} two bores h ¹ and i ¹ for the passage of a drilling spindle h and a screwdriver i, on which there are single stops η and ο . Hand levers / and tn allow the spindles h to be pushed up

and i, die.jin. suitably get their drive by bevel and spur gears. The through-holes q ¹ , h ¹ and i ¹ lie in an arc of a circle around the axis of the pivot pinÄ on the lug d; a vertical bracket s is attached to the machine frame g ^{, which is stranded with a slot, s 1 and} enables the passage of a threaded bolt p ¹ which is screwed firmly into the stop ρ; tightening is done by a nut / ·.

The stops t limit the 'pivoting movement of the Böckc'hens d in such a way that the hole in the ledge and the support ii ¹ coincide exactly with the holes h ¹ and i ¹ .

For the work of the machine, the centering rod / is first so hochgesäbobeni that. he through the bayonet lock / ¹ . the centering sleeve q can be determined .; while the lug d is in the position according to Fig. 1. Then the inserted shoe with heel & is placed on the centering pin / and the spindle e is turned down so far that a firm clamping takes place. Any differences in the last, insole and heel height cause the centering rod / together with the sleeve q and its stops /? are moved downwards against the spring action · The centering rod · / is then removed from the last, and the bolting work and the tightening of the fastening screw can then be carried out quickly and accurately by means of the corresponding pivoting movements the other auxiliary organs involved in the adjustment can still be modified in many ways without the invention suffering a fundamental change as a result.

Claims (2)

Patent claims: i. Machine for centering and fastening the heel "in the case of inserted shoes with a hole in the last for the passage of the centering rod, tool and fastening means, characterized in that The like) are clamped, the axis of rotation of which lies outside the axis of the centering rod (/), and the latter and the tools (drill, screwdriver, etc.) are placed next to each other in the machine frame on an arc of a circle that starts from the hole in the bar Pivoting the carrier (d) is described. 2. Machine according to claim 1 with a stop to limit the advance of the tools when driving the fastening means, characterized in that the stop (/?) For the work spindles is arranged on a spring-mounted bushing (q) mounted on the upper bearing eye of the frame (g) which is determined on the machine frame in a position corresponding to the driving depth of the fastening means, for which the 'centering pin (/) is used as a depth tool.
