Lasting machine with a "device for pinching the heel

The combination of a toe and heel lasting device in a single machine brings a significant simplification all the tweaking work with it, which so far has mostly been done on different machines, namely a tip tweaking machine and a special heel lasting machine will.

The combination of a toe and heel wrapping device in however, a single machine presents certain difficulties opposite. These are due to the fact that the position of the heel part to the front part of a last is of the size and mainly depends on the breakdown of the groin. Should both right and left shoes be on such a machine be pinched, then it must be taken into account that the heel in relation to the front part is to the right and the other is offset to the left. Accordingly, the curve of the groin floor in the heel area also falls once to the left side and the other time to the right side stronger

The present invention is based on the task For a lasting machine to create a device for lasting the heel au, which makes it possible to precisely adjust the heel slide on the position of the bottom of the strip in the predetermined by the blast and size of the last inserted into the machine Align the heel area. To solve this problem, the invention proposes that the holder for the heel slide to adapt the position of the slide to the angle of the angle of the last used in the machine to the horizontal plane by pivoting in a vertical plane parallel to the vertical strip center plane as well as in their height with respect to the groin base by a movement perpendicular to the groin base and to adapt to the Preferably the size of the last in respect of its longitudinal axis is continuously adjustable.

When using the device according to the invention for pinching the heel can adjust the bracket for the toe slide regardless of the size and size of the last Last training can be left unchanged, so that only the holder for the heel slider changed too needs to be.

If both right and left shoes are to be pinched on the same machine, the invention provides that the holder for the heel slider can be moved transversely to the longitudinal axis of the groin and around an axis

109825/0328

can be pivoted perpendicular to the strip bottom. To this also the different course of the curvature of the groin base To be taken into account, depending on whether a right or a left Shoe is to be pinched, according to the invention, the holder for the heel slide in its angular position to the horizontal plane by pivoting in a vertical plane perpendicular to the vertical strip center plane, preferably be infinitely adjustable.

The invention is described below with reference to the embodiment shown in the drawing, further features of the invention are explained. In the drawing, for the sake of simplicity, the tip pinching device is shown omitted.

The heel lasting device according to the invention rests on a bearing designated as a whole by 1. On this, a slide 2 is displaceable towards and away from the last in the direction of the longitudinal axis of the last. For this purpose, groove-like guides are provided on the two inner longitudinal sides of the bearing, which are formed by the strips 3 screwed to the bearing. The slide 2, hereinafter referred to as the longitudinal slide for short, is designed as a hydraulic cylinder. A piston 4, which can be acted upon twice and which continues ^{into a piston rod 4 1 on either side, can be displaced in this.} The piston is arranged stationary with respect to the cylinder or longitudinal slide.

A cam plate 5 comes against both sides of the bearing 1 to the system, which by means of the contra-angles 6.7 on the machine

109825/0328

frame is posted. .In.the.circular.curve 8 run two an.den side walls of the bearing mounted rollers 9, 10. The bearing is by means of the clamping lever 11 against a the cam plates 5 can be clamped. On one of the cam plates are the bearings 12, 13 for one at its upper end with a Shaft 14 provided with handwheel 23, on which a snap 15 is formed, which communicates with worm wheel 16 cooperates. The worm wheel sits on a shaft 17 which extends below the longitudinal slide 2 and through provided in the cam plates bearing bores is passed. On the side of the machine on which the Worm wheel is located, the relevant end of the shaft 17 is received by a bracket-shaped bearing piece 18. On the shaft 17 sits a sprocket 21 over which the chain 19 is placed (FIG. 2). One end of the chain is attached to the sprocket and the other end to the bracket 20, which is screwed to the bearing 1 (screw 22).

By operating the handwheel 23, the angular position of the bearing 1 and thus also that of the slider (scissors) head described in detail below can be roughly adjusted depending on the respective size of the footwear to be tweaked. By applying pressure medium supplied to one or the other side of the piston 4 via the connection 4 ″ provided on each piston rod, the slide 2 is moved in the direction of the longitudinal axis of the bars either towards or away from the bars

109825/0328

the carriage 2 and thus again the scissor head adjust depending on the shoe size. The control this movement will be described later

On the longitudinal slide 2 is the guide for a total of 24 designated slide, which is in the right Angle to the longitudinal slide 2 is displaceable; the sled 24 is hereinafter referred to as the cross slide for short. The guide provided on each side of the cross slide is used in each case formed from a pair of strips 25, 26 which is attached to the longitudinal slide. The overhead ledges are 25 of the slide 24 under grips, so & ss this is fixed in the vertical direction at the same time. Of the Carriage 24 is forked to the front, that is, towards the strip carrier, not shown, and has at the fork ends each has an upwardly protruding tab 24 *.

The drive for the cross slide 24 is constructed as follows ™:

From the sides of the cross slide that are on the outside of the device ago a bore 27, 28 is introduced into these in each case, in which a piston 29 or 30 can be displaced u. The pistons can be acted upon on one side with pressure medium, which flows from the ends 31 and 32 to the cylinder bores 27 and is fed. The pistons are arranged stationary with respect to the cross slide. They support themselves with their

1098 25/0328

beat side opposite end against that of Figure 2 visible strips 33 »34- which are connected to bearing 1 are. The bars 33 »34- also serve as a stop s limit for the movement of the cross grinding. To this Purposes act the bars 33ι 34 with the cross slide provided screws 35 »36 together, which are adjusted by hand can be that the necessary lateral displacement of the cross slide results in the individual case. This is moved to one side or the other, ^ e after, whether right or left shoes should be pinched.

In addition to the rough adjustment for the angular position described above of the longitudinal slide or the scissor head, a fine adjustment is also provided for the angular position. This will formed by the following pieces of equipment:

In the space delimited by the fork of the cross slide 24 there is a pivot bearing 38 (FIG. 4) which is designed similarly (forked) to the cross slide. The two pivot axes 37 are each mounted on the upper end of the tabs 24 * of the cross slide 24 and the tabs 38 '(FIG. 5) of the pivot bearing 38, which likewise extend upward from the fork. The pivot bearing 38 is supported on the cross slide 24 by means of the adjusting screw 39. By manually adjusting the screw, the inclination of the pivot bearing with respect to the cross slide 24 can be adjusted and thus the angular position of the scissors head to the strip base can also be changed. _109825/0 3 ₂ 8

On the pivot bearing 38 by means of the screws 41 is a 40 is attached to the holder, on which the actuating means for the directly on the base plate 42 of the total with 43 bez eichneten scissor head acting adjustment devices are provided.

Vie from Figure 5 can be seen in the holder 40 of the left and right side of the device a hole 45, 45 * introduced, which act as a cylinder for the piston 46 or 47 serves, which can be acted upon with pressure medium from the left or right side of the device. The respectively charged KöJLben presses down on one of the base plate 42 projecting driver 48 and consequently causes a pivoting about the central axis 44 'of a shaft 44, its bearing will be described. As a result of this pivoting, the scissors head 43 can about an axis perpendicular to the strip base be pivoted and thus aligned against the vertical center plane of the last. This setting option proves to be useful when left and right shoes are to be pinched on the device.

The base plate 42 is also adjustable in height, the height adjustment being carried out with a pivot of the base plate about an axis running parallel to the longitudinal axis of the bar in order to change the inclination of the side head 43 is coupled transversely to the longitudinal axis of the bars. This places the scissors in the arch of the groin in the heel customized.

109825/0328

For the two last-mentioned adjustments, two cylinder-piston assemblies are accommodated in the holder 40. For this purpose, a (vertical) cylinder bore 51, 52 is formed in the bearing to the left and right of the shaft 44, in which the pistons 49 and 50 can be displaced (FIGS. 4 and 5). The pistons are acted upon from the lower end of the cylinder bores. The working end of the pistons presses directly against the base plate 42. The setting of the base plate is regulated by a switching valve, generally designated 53, which is connected to the base plate 42 (FIG. 4) and on its (working) side facing the bar, corresponding to the base of the bar ( concave) is worked out. If, in the course of the height adjustment, the working side of the valve to the left or right of the shaft 44 comes to rest against the bottom of the strip, then the piston acting on the side in question is brought to a standstill. However, the piston on the other side continues to work until the pin 53 'protruding from the working side of the valve is completely pushed back into the valve body. In this way, the entire pressure medium supply is then also switched off. In this way, the base plate 42 has leveled off in a position corresponding to the curvature of the strip bottom. This is possible in that the shaft 44 is accommodated in a conical bore 54 (FIG. 5) of the bearing 40, within which it can perform a pendulum movement to the left or right side of the device. The shaft 44 is also rigidly connected to the base plate 42 for the scissor head. For this purpose the shaft is with a

109825/0328

their upper end provided collar 44- "in the base plate 42 let in. At its lower end 44 "the shaft 44 has a collar 44 '" against which one end of a pressure. spring 109 comes to rest, which is supported with its other end against the bearing 40. Through this spring the Shear head 43 lowered again when the pistons 49, 50 are no longer acted upon by pressure medium.

The above-mentioned valve 53 not only actuates the cylinder-piston assemblies 49, 51 and -50, 52, but also one more Cylinder-piston arrangement 103 identified in warehouse 40, 106 (Figure 4). As soon as the valve pin 53 'is pushed back due to its contact with the bottom of the groin, the piston 103 becomes pressurized from above with pressure medium. This shifts the piston moves back against the force of the spring 104 in the cylinder bore 106 and takes a spanning the bar Frame 105 with, wherein the piston presses on the lower web of the frame. Once the overhead The web of the frame 105 is pressed against the bar, »the movement of the piston 103 comes to a standstill. In order to the bar is clamped on the upper side of the valve 53, which is designed as a bar support. The frame 105 is between the angle pieces 107, 108 (£ igur 6) out, which are attached to the housing of the scissors head 43. The valve 53 also controls the ifcuck in the cylinder-piston arrangements 71, 73 and 72, 74 described below (FIG. 6).

109825/0328

In the base plate 42 of the scissors head 43, as can be seen from FIG take a roller 57 and 58 with two scissor support plates 59, 60 are connected. The two plates are held together by a hinge 61. On the carrier plates the scissor blades 62, 63 are rigidly attached in such a way that the insole when pinching under-reaching work surface of the scissors protrudes over the carrier plates. The two scissor blades are in themselves articulated in a known manner.

The drive provided in the machine according to the invention and described in detail below for the Scissors and the heel cushion are characterized by a particularly compact design. To this end, it is up to both of them Scissor support plates 59, 60 each one end of two Handlebars 64, 65 attached. The other end of the link is by means of the collar bolts 67, 68 with a two-part traverse 66 connected, which is clamped at the same time by means of these bolts with a bush 69, the front end of which " a cross member 70 which is wider than the cross member 66 carries. This is also divided horizontally so that between their two halves the rods 71 ', 72' of the pistons 71 and 72 that can be clamped into the cylinder bores 73, 74 are displaceable and acted upon on both sides.

In the known drive for the scissors, the handlebars are.,

which is the non-positive connection between a drive ^{f 10 9825/03 28}

device and make the scissor support plates, in front of the drive device. This gives the whole scissor drive a comparatively great length. According to the invention the handlebars are essentially next to the operating cylinders, which leads to a considerable saving of space.

If the pistons 71 »72 are acted upon with pressure medium from behind, then the traverse 70 is moved forward, that is to say towards the ledge, with the bushing 69 and thus also the links 64 ·, 65 connected to this are taken along. The movement of the on the base plate 42 by means of the rollers 57ι 58 and the curves 55 »56 guided scissor support plates 59, 60 and thus also of the scissor blades 62, 63 takes place in a manner known per se, so that this does not need to be discussed further. The provision of the scissors into their starting position takes place in that the pistons 71 »72 from the other side, i.e. from the front, pressurized medium is applied.

A ring 77 comes to rest against the rear end of the sleeve 69 and is fixedly arranged on a rod 78 which is guided freely through the sleeve 69. A spring 79, which is supported on the bearing 80, presses against this ring. The spring 79 therefore seeks to move the rod 78 forward. At the front end of the rod 78 a cross member 81 is provided, to which a holder 82, 83 for the heel cushion, not shown, is articulated on both sides of its center. The displacement of the rod 78 after

109825/0328

At the front, the bottom of the (U-shaped) heel cushion is shifted in the direction of the rear seam of the upper and is attached there. Then the heel cushion should be pressed against the shaft from the side. For this purpose, a cylinder-piston arrangement with the cylinder bores 84, 85 is provided for each holding arm 82, 83 of the heel cushion, in which the pistons 86 and 87 can be displaced on one side with pressure medium. The piston rods 86 'and 87' are led out of the cylinder bores 84, 85, each of which has a spring 88, 89 which is supported with its rear end against the piston and with its other end against the housing of the shear head 4-3 . At the front end of the piston rods 86 ', 87' is in each case a roller 90 provided iterungsteilen with an obliquely extending guide edge 91 of the H _a 82 cooperates 83 for the heel pad. A spring 92, 93, which is fastened to the handlebar 94 or 95 fixed to the housing, engages each of these mounting parts. The heel cushion is positioned against the last by means of the aforementioned spring 79 and * by acting on the pistons 86, 87. By means of the springs 92, 93, the heel cushion is lifted from the last as soon as the pistons 86, 87 are under the action of the compression springs 88, 89 can be brought back to their original position. The springs 92, 93 are designed to be stronger than the spring 79.

For the longitudinal slide 2 described in detail above

109825/0328

a controller is provided which controls the movement of the Brings the slide and thus also that of the scissor head carried along by it to a standstill as soon as the heel cushion hits the heel butts against the vertex of the inguinal heel. For this purpose there is a Angled sensor 97 is displaceably mounted and a switching valve designated as a whole with 96 is provided. The arm 97 'of the feeler protruding into the space enclosed by the heel cushion comes in the course of the movement of the heel cushion in sighting on the ledges on this to the plant. As a result, the other arm 97 "» which is in a groove one with the guide part 98 connected to the scissors head 43 is displaceable in the longitudinal direction, pushed back, with a roller 99 at one end of a lever 100 which is hinged at its other end to a bearing 101 connected to the valve 96 runs against a bevel provided on the free end of the arm 97 ″. As a result, the lever 100 presses the valve pin 102 into the valve and thus switches the pressure medium supply to the piston 4. The valve 96 controls simultaneously the pressure medium supply to the cylinder-piston assemblies 49, 51 and 50, 52. The switching valve 96 is attached to the guide part 98.

The machine according to the invention described above operates as follows:

In the starting position, taking along the Schrenk head 43 of the cross slide 24 by applying pressure to the cylinder 29

109825> 0328

or 30 placed in the position required for pinching left or right shoes is required. Another setting of the scissor head depending on whether right or lin_ke shoes are to be pinched, is done by beating them the piston 4-6 or 4-7.

After this, by acting on the piston 4 · the longitudinal slide 2 moved up to the ledge. This movement comes to a standstill as soon as the feeler 97 hits the bars strikes and as a result the switching valve 96 is actuated. This releases the pressure medium supply to the cylinder-piston arrangements 49, 51 and 50, 52 off, making the scissor head is raised and pivoting about an axis running parallel to the longitudinal axis of the strips. Through this the position of the scissors is adjusted to the curvature of the groin floor. The activity of the two aforementioned cylinder-piston arrangements comes to a standstill as soon as the valve pin 53 'of the valve 53 has been pushed back into this. This results in a first supply of pressure medium to the cylinder 106 triggered, as a result of which the piston 103 is pressed down and the strips by means of the frame 105 on the strip support is clamped. At the same time, the valve causes a pressure reduction in the cylinders 73 »74- on the side of the Piston 71 »72, which faces the last. The pressure on this side of the pistons 71 »72 was already in the starting position available.

By means of the spring 79, the heel cushion is pressed against the last 109825/0328

- 16 -

in the area, pressed from the rear apex line. The pistons 86, 87 are then acted upon with pressure medium, so that the heel cushion is also pressed against the last against the strings.

The pistons 71 »72 are now from their other, so the Last side facing away from the pressurized medium, whereby the scissors 62, 63 pivot and the shaft edge put it on the insole. At the end of the pivoting movement, the piston 10J with the full one is located in the hydraulic system Pressure is applied so that the bar is placed firmly against the (pivoted) scissors 62, 63, which the Formation of a sharp lasting edge and a good bond between the lasting fold and the insole favors.

From the above it is readily apparent how all Parts of the device according to the invention return to their starting position can be brought so that it does not need to be discussed in detail.
