hollow sleeve 98. The flax of the sleeve 98 is pivotally mounted with the possibility of vertical movement of the working tool 92. The piston rod 99 of the air motor 100 is installed with the possibility of swinging on the axle 101 mounted on the suspension 86. The piston rod 99 slides in the hub 102, in which the load cylinder 103 is hinged. To ensure the vertical movement of the working tool 92, the air motor 100 moves the power cylinder 103.

The working tool 92 in the form of a wire brush is installed in such a way that the bottom surface of the edge of the brush is located between the teeth 75 of the plug 74,. On block 96, an electric motor 104 is rigidly mounted, which is connected by a pulley 105, a belt 106 and a pulley 107 to a shaft 108 rotating in floor sleeve 98.

The shaft 108 is connected via a pulley 109, repair; 110 and a pulley 111 with working tool 92, so that the working tool 92 is rotated.

Between the crossbar 68 and the suspension 86 ka shaft 72 fortified cam 112.. On the flange 113, mounted on the housing 85, pivotally sits the lever 114. A spool 115, mounted on the flange

113, has a rod 116, movably fixed in the body of the spool with the possibility of movement from the lever

114. The walking rod 116 is pressed against the upper part of the lever 114 with compressed air entering the valve 115 through the hose 117. The roller 118, which is in the lower part of the lever 114, contacts the edge of the cam 112 using the valve stem 116 under the action of the compressed air entering the hose 117. The spool 115 and the hydraulic motor 89 are connected to one another and to the hydraulic system in such a way that they form a servo-mechanism of a known construction in which the relative movement in one or the other direction of the spool 115 you yvaet corresponding in magnitude to the movement in one direction or the other relative to the piston rod 89 of the hydraulic motor.

A liner 119 is attached to the housing 85. Continued 120 of the spool housing 121 is mounted for sliding reciprocating to the liner 119.

A compression spring 122 located between clip 123 fixed on the liner 119 and clip 124 fixed on the body of spool 121 presses against the slide and its extension 120 until roller 125 in front of the continuation 120 of the slide begins to contact the surface 126 cam 127.

The cam 127 deflects forward to the shaft 128 fixed on the housing 85. In front of the shaft 128, the cam 127 is mounted on the stem 129 secured to the coupling link 130. The other end of the coupling lip 130 is deflected with a pin 131 to the tooth 132 fastened on the block 96.

The spool pin 133 of the spool 121 moves in a straight-line return-post manner in the spool housing and in the extension of the spool 120. A port 134, installed in the extension 120 of the spool, is connected to one end of the spool rod 133. The pipe 134 passes through a slot in the insert 119, so that the pipe and hose 135, which is worn on the pipe, are reciprocally mounted relative to the insert 119. Hose 135 is connected to a source of air transported through the nozzle 134 into the cavity, extending the spool 120, thereby pressing the spool pin 133 backwards. The movement of the spool rod back is limited by the pin 136 mounted on the end of the lever 137. The lever 137 is movably seated on the pin 138 located on the housing 85.

The end of the lever 137, the opposite end with the pin 136, is in line with the piston rod 139 of the air motor 140, located on the housing 85. The piston rod 139 is directed backward from the air motor 140 and is pressed forward by the return spring of the air motor 140.

The spool 120 and the hydraulic motor 94 are so connected with each other and with the source of hydraulic fluid that they form a follow-up servo-mechanism in which the relative movement in one or the other direction of the spool rod

133 relative to the middle position in the body of the spool 120 causes a corresponding movement in one 5 or other direction of the piston rod 95 relative to the hydraulic engine 94. A shaft 141 is located on the shaft 72. At one end of the rod 141 there is a probe 142, 10 passing under the teeth 75 of the fork 84 and in between. A cap 143 is put on the back of the shaft 72, and the spool body 144 is rigidly connected to the cap 143. The spool 144 has a new stem 145, mounted with the possibility of reciprocating movement in the spool body 144. One of the spool ends

145 moves in coordination with one of the 20 parts of the rod 141. Spool

stem 145 is pressed back by spring

146 shrink located between the rear part of the body of the spool 144 and the flange 147 of the spool valve.

5 The cap 148 is attached to the back of the spool body 144. The pipe 149 is connected to a compressed air source so that the air can overcome the force of the spring 146

0 and squeeze the spool rod 145 forward in the body of the spool 144.

The spool 144 and the air motor 64 are so interconnected and with a source of hydraulic fluid

5 systems that form a trace w 1st servo mechanism, built in such a way that reciprocating movement in one or the other direction of the slide valve stem 145

Q causes a corresponding movement in or in another direction of the piston rod 65 relative to the air motor 64.

On the plug 74 gfy pomosh springs 150

5 the screen 151 is strengthened, located between the teeth of the 75 forks 74 and above the probe 142.

In the non-working state of the machine, the piston rod 11 protrudes from the air motor 10 for mounting the stand 5 and the elements located on it — the caliper 6 and the toe stop 20. The first finger 56 is relatively far from the pin 3 and the pin 4. The piston rod 14 is retracted into the air motor 13 for installation of the ladder stop 6 in position. The piston rod 16 of the second pneumatic flexor 15 is elongated to place the toe support in the stalk.

The cam 21 is retracted from the spool. The slider 2 is at one end of the turntable 7 The second finger 57 is engaged with the lever 46, and the cam 47 is turned in such a way by the spring 48 that the valve 51 is open. The pin 4 is in line with the axis of rotation of the turntable 7 and the axis of the working tool 92.

Shaft 37 rotates. The pneumatic clutches 27, 31 and 34 are disengaged. As a result, the gear sprockets 41 rotate on the fixed shaft 24 with an asterisk 39, the sprocket sprocket 43 is driven into rotation on the fixed shaft 30 by an asterisk 42. The shaft 33 is stationary. The cam 53 on the shaft 30 is in the position shown in FIG. 9.

The piston rod 61 is extended from the air motor 62, with the result that the pawl 59 on the pin 60 is turned inward and is in the recess 58 of the turntable 7, fixing it. The pressurized air does not enter the cap 148 through the nozzle 149, and therefore the spring 146 pushes the spool rod 145 to the rear position in the body of the spool 144. As a result, the central follower servo mechanism connecting the spool 144 to the air motor 64 moves the piston rod 65 in the air motor 64 and thus places the caliper 66 together with the working tool 92.

Piston rods 71 are extended from the engines 70 and position the working tool 92 in the upper position. The spring 84 tends to turn the fork 74 counterclockwise with respect to the axis of the trunnions 76. In this case, the teeth 75 of the fork 74 are lowered down to the position in which the nozzle 81 abuts against the surface 83.

The piston rod 79 is pulled back from the air motor 77 to a position at a certain distance from the protrusion 80. Compressed air enters the body of the spool 115 through a hose 117, tends to move the spool rod 116 to the left (Fig. 20), pressing it to the upper end of the lever 114. The cam 112 actuates the lever 114, which moves the spool valve

gage 116 in the middle position in the body of the spool 115. As a result, the following servo-mechanism, connecting spool 115 and hydraulic motor 89 remain in the middle position in the hydraulic motor 89. At the same time, the tooth 75 of the fork 74 is located almost in the horizontal plane, and the axes rotation of the pulley 111 and the working tool 92 are located in a horizontal plane. Air motor 140 pushes the piston | Stroke 139 backward, thereby causing the pin 138 to move the spool pin 133 forward in the body of the spool 121. This overcomes the resistance of the compressed air that enters the continuation cavity 120 of the spool across the spindle 135 through the nozzle 134, with the result that the servo-mechanism, located between the spool 121 and the pneumatic engine 94, pushes the piston rod 95 forward relative to the air motor 94. As a result, the working tool 92 is located in a forward position relative to the air juice 85, while the working tool 92 is in the front position with respect to the tooth 75 of the fork 74. npysQiHa 122 pushes the spool 121 forward, the roller 125 rests against the cam surface 126. Power cylinder 103 is pushed up above the piston rod 99, fixing the working tool 92 in the upper position relative to the block 96 and in the raised position above the teeth 75 of the fork 74. The electric motor 104 rotates the working tool 92.

The machine works as follows.

The shoe blank 152 consists of the top of the shoe taut on the shoe 153 and the insole located on the track of the shoe. A shoe with a padded bottom top shoe is placed with the sole upwards on pin 4, which fits into the usual blind hole of the heel part of the shoe, with the nose part facing rack 5. Then the pneumatic control valve 10 is started to move the rack 5 together with the insole stop 6, with the toe rest 20 and the first PSC 56 from the pin 3 under the action of the elastic force of the compressed air until the toe rest 20 contacts the toe of the pad. As a result of this contact, the lever 18 and the toe support 20 rotate clockwise (Fig. 1) around the axis of the finger 19, as a result of which the cam 21 intersects and displaces the valve. When the slide is shifted, the pneumatic motors 13 and 15 are started. As a result, the pneumatic motor 13 raises the stem support 6, and the pneumatic motor 15 lowers the lever 18 and the nose support 20.

The toe stop 20 has, on the side opposite to the lever 18, a protrusion movably mounted on the finger 19.

When the toe pad is lowered, it moves away from the edge of the toe of the shoe upper, which, as a result, does not interfere with the operation of tousling the pulling edge of the workpiece. Raising the stack support 6 under the action of an elastic force of compressed air allows it to come into contact with the front part of the shoe blank and tilt it relative to pin 4 until pin 4 touches the edge of the blind hole in the block 153. fixing the workpiece on the slider 2 to perform the operation.

After fixing the shoe, the shoe includes a spool on the slider to start the air motors 70, retract the piston rods 71 and direct the air into the nipple 149. As a result of the air motors 70 start, the shaft 72 is lowered, with it the working tool 92 and the tooth 75 of the fork 74, turning them about the axis of the rods 69 under the action of the elastic force of compressed air, which actuates the air motors 70. The compressed air flowing through the nozzle 149 controls the movement of the spool pin 145 forward relative to the spool body 144 , the pre-elastic spring force of the spring 146, as a result of which the rod 141 and the probe 142 move forward. This movement is forward by means of a servo-mechanism tracking mechanism connecting the slide valve 144 and the air motor 64, which actuates the air motor 64, which pushes its piston rod 65 forward , moving forward the caliper 66 together with the working tool 92 and the teeth 75 of the fork 74.

The movement of the working tool 92 and the teeth 75 of the fork 74 stops when the tooth 75 of the fork 74 engages over the edge of the workpiece top 152 in one of its front portions, causing the fork 74 to rotate clockwise relative to the axis of the pins 76 against the action of the squads 84 until until the piston rod 79 contacts the protrusion 80. Moving the working tool 92 and the teeth 75 of the plug 74 forward stops when the probe 142 touches the side of the shoe upper, then moves back on the shaft 72. With this movement of the probe 172 slide valve stem 145 moves back in spool body 144 against the action of compressed air in cap 148 until spool pin 145 reaches middle position in spool body 144. Slide rod 145 is mounted in the middle position caused by installing rods 141 in the middle position on the shaft 72, causes the next servo mechanism, connecting the spool 144 to the air motor 64, to stop moving the piston rod 65 forward.

After these actions, the spool is shifted.

The slide of the spool serves as a means of triggering the air motor 100 towards the lowering of the power cylinder 103 under the action of compressed air, which leads to the lowering of the working tool 92 relative to the axis of the hollow arm 98 until the elements of the working tool 92 contact the edge of the shoe upper 152 between the teeth 75 forks 74. The slide of the spool also starts the air motor 62, turning at this time the pawl 59 from the recess 58 in which it was located, uncoupling the turntable 7. Then the coupling 31 is turned on, which connects the rotating tooth sprocket 43 with shaft 30 to rotate shaft 30. Rotation of shaft 30 through gears 28 and 29 is transmitted to a turntable 7, which rotates relative to the axis of the flange 25 and rotates the slider 2 and the top shoe of the shoe 152, tightened on the shoe, the center, which is in line with the pin 4 and lies in the center of the curvature of the cable track portion.

Contacting the teeth 75 of the fork 74 with the edge of the workpiece shoe upper 152 causes the working tool 92 to lower until it touches the edge of the shoe upper shoe 152. At the same time, the heel part of the shoe top edge moves past the work tool 92. This design ensures that the workpiece is extruded the top of the shoe when moving it relative to the working tool 92. If the working tool 92 touched the edge of the workpiece top of the shoe 152, and the top shoe of the shoe on the shoe is fixed, then the working tool Item 92 would wipe the groove in the edge of the shoe upper. This does not occur due to the simultaneous lowering of the working tool 92 until it touches the edge of the top blank of the shoe 152 and the beginning of the movement of the edge of the top blank of the shoe 152 relative to the working tool 92.

During the movement of the heel part of the workpiece shoe upper 152 relative to the working tool 92 and any other shoe top workpiece for the gastric joints, the work tool 92 must move up and down in accordance with the profile of the shoe track, which is ruffled and reciprocating along the contour of the workpiece. blanks for installation at the required distance inwards from the outer periphery of the edge of the upper shoe blank that is processed. The central plane of the working tool, located at a right angle to the axis of rotation, should be inclined during the process of moving the sections of the shoe top workpiece to be machined relative to the working tool 92 so as to be at a right angle to the plane of the workpiece section. shoe upper 152, which is processed.

The reciprocating movement in the vertical plane of the working tool 92 when moving the edge of the workpiece top of the shoe 152 relative to the working tool 92 is performed because the working tool 92 perceives the swinging movement of the cross member 68, and likewise elastically pressed down by the pneumatic motors 70,

The movement of the working tool 92, reciprocating in a vertical plane during the movement of the edge of the top blank of the shoe 152 relative to the working tool 92, is carried out by a probe 142, which is pressed against the side of the top blank of the shoe by compressed air in the cap 148, Following servo mechanism 144 with an air motor 64, is constructed in such a way that the piston rod 65 is stationary, while maintaining the immobility of the working tool 92 in the front-back direction, when the spool rod 145 is on average positioned and in the body of the spool 144, and the rod 141 is in an average position on the shaft 72. The movement of the probe 142 forwards when the side portion of the top shoe of the shoe 152 sideways from the probe moves the spool rod 145 to move in the body of the spool 144, which forces the matching the servomotor is controlled by the air motor 64 in a specific manner. In this position, the piston rod 65 is displaced forward and thus moves the working tool 92 and the probe 142 forward until such time as the probe 142 does not touch again the side of the upper shoe blank 152 and thereby causes the rod 141 to move the spool rod 145 into the middle position in the body of spool 144, movement of the probe 142 back, caused by pushing back the probe 142 by the side side section of the shoe top, causes the rod 141 to move back from its middle position on the shaft 72, at which the rod 141 pushes the piston rod to 145 back in slide housing 144.

As a result, the respective servo mechanism controls the air motor 64 in such a way that the piston rod 65 moves back and moves the working tool 92 and the probe 142 back until then. As long as the side of the shoe top does not stop pushing the probe 142, back and the slide stem 145 will not occupy an average position in the body of slide 144,

The inclination of the center plane of the working tool 92 is effected with the installation of the teeth of the plug 74 together with the housing 85 for rotation about the axis of the shaft 72. In the process of moving the cr4 of the upper shoe 152 past the teeth 75 of the fork 74, which are pressed down to the edge of the upper shoe of the shoe, the tooth 75 is rotated about the axis of the shaft 72 so that the plane connecting the bottom of the teeth is parallel to the plane of the edge of the top shoe of the shoe against which eub 75 rests. This causes the cam 112 to rotate in one direction or the other, and thus The lever 114 causes the slide rod 116 to move in one or the other side of the middle position in the spool body 115. As a result of the slide stem 116 in one direction or in the other from the middle position in the slide body 115, the following servo mechanism connects the slide valve 115 with a hydraulic engine 89, causes the displacement of the piston rod 90 of this engine in the direction of rotation of the housing 85 to one or the other side until the spool rod 116 is again in the middle position in the housing lot 115. Turning the body 85 in this direction causes the working tool 92 to rotate in the corresponding direction until its central plane is in a plane at a right angle to the plane. 75 teeth forks 74.

When the top shoe is rotated, tucked into the shoe, the second finger 57 comes out of contact with the lever 46, with the result that the spring 48 brings the cam 47 close to the spool 51. When the shaft 30 rotates 180 from its initial position (Fig.9), The cam 54 pushes the valve 55 at this moment and opens it. The instant opening of the spool 55 triggers the pneumatic clutch 34, which connects the shaft 33 to rotate in conjunction with the shaft 37. The instant opening of the spool 55 also causes the pneumatic clutch 31 to shut off, resulting in the rotation of the shaft 30 and the rotary table 7. The instant opening of the spool 55 also actuates the air motor 62, switching the pawl 59 into the recess 58 to fix the rotary seat

7. After the turntable 7 is turned 180, the result is that the working tool 92 can tangle the heel part of the edge of the shoe top from one area to another, the turntable 7 rotates, as well as the shoe top, then on the pads, stops, the turntable is fixed in a stationary position and the shaft 83 begins to rotate. The rotation of the shaft 33 is transmitted by means of gears 26 and 32 to the shaft 24 and gear 23, through which the rack 22 moves along with the slider 2 and the top blank. drive, tucked into the shoe, in the longitudinal direction relative to the working tool 92 in such a way that the working tool 92 touches the side of the top blank of the shoe 152, and the top blank of the shoe moves in the direction from the heel to the toe of the shoe blank relative to the working tool 92, and the tool thus ruffles the side portion of the shoe's top blank. This longitudinal movement of the shoe blank in the direction from the heel to the toe relative to the working tool 92 continues until the first finger 56 touches the lever 46, which interacts with this finger after the second finger 57 disengages the lever 46 during the rotation of the shoe upper 152 relative to its axis.

The described movement of the finger 56 in the direction of the pin 3 with the help of the air motor body 10 continues until the toe stop 20 touches the end of the toe of the top of the shoe, and the first finger 56 is in the position when the center of curvature of the right part of the pad track coincides with the axis of rotation of the turntable 7 formed by the center of the flange when the slider 2 finishes moving in the longitudinal direction on the stationary turntable 7, and the top shoe preparation finishes moving in the direction from heel to toe relative to the working tool 1enta 92.

When the first finger 56 of the lever 46 is engaged, the cam 47 opens the valve 51. As a result of opening the valve 51, the air motor 62 rotates the pawl 59, withdrawing it from the outlines 58 in which it was located, so as to allow the rotary table 7 to rotate. As a result of opening the spool 51, the pneumatic clutch 34 is deflected and movement in the longitudinal support slide stops, which leads to a rotation of the rotary table 7. In the toe section of the upper workpiece strut, the bottom of the shoe has a tip upward to the inner SIDE of the shoe blank. Before this time, the tooth 75 of the fork 74 is located almost horizontally, since the piston rod 79 rests on the protrusion 80, and the working tool 92 is mounted relative to the probe 142 by means of an air motor 94 so that the tooth 75 of the fork 74 is flush with the edge of the workpiece shoe upper movement. Due to the inclination of the footwear edge of the shoe upper and inward in the toe part of the shoe upper, this relatively extended position of the working tool 92 relative to the probe 142 may cause the working tool to contact the shoe upper edge of the shoe more than when the outside of the shoe upper is tangled. toe part. In order for this not to occur and for the tooth 75 of the fork 74 to continue to contact the edge of the top of the shoe in the toe part, the working tool 92 is retracted relative to the probe 142 by adjustment, the tooth 75 of the fork 74 is given the opportunity to turn upwards relative to the axis of the pins 76 by adjusting in the process of moving the workpiece top of the shoe relative to the working tool. Opening the spool 51 with the first finger 56 also causes air to descend into the air motor 77, with the result that the downwardly resilient force applied to the plug 74, supported by the shoe upper, on the side of the air motor 70 rotates the fork 74 upwards relative to the axis of the pins 76, while The piston rod 79 is drawn into the air motor 77 until the tooth 75 of the fork 74 is in a plane almost parallel to the surface of the edge of the shoe top.

Opening the spool 51 with the first finger 56 also lowers the air from the engine 140 in such a way that the return spring of this air motor pulls the piston BJTOK 139 forward into this air motor, moving the pin 136 backward relative to the spool rod 133. As a result, the compressed air enters the cavity. spool 120 through hose 135, moving the spool rod 133 backward until it again engages with pin 136. This backward movement of the spool rod leads to its displacement from the middle position neither in the body of spool 121, and as a result, using a servo mechanism connecting the spool 121 to the engine 94, the air motor 94 moves its piston rod 95 back, moving the cross bar 93 of the working tool 92 and the block 96 together with the working tool 92 backwards relate to the axis of the pins 91. As a result of this backward movement of the block 96, the rocker 130 is lowered, which raises the cam 127 relative to the axis of the i 128 pin. The cam surface 126 has a gradually increasing radius from top to bottom relative to the axis of the pin 128. After that (the surface of the cam 126 pushes the pusher 125 along with the extension of the spool 120 and the body of spool 121 back until the spool rod 133 is again in the middle position in the body of spool 121, as a result of which the air motor 94 stops backward movement of the piston rod 95 and the working tool 92.

When the upper shoe is rotated, the first finger 57 stops interacting with the lever 46, as a result of which the spring 48 moves the cam 47 to the spool 51. When the shaft 30 rotates 180 from the initial position, rotate the toe of the shoe upper 180 along the working tool 92 , cam 53 pushes slide 54, opening it.

As a result of opening the spool 54, the pneumatic clutch 31 is turned off and the air motor 62 turns the pawl 59, inserting it into the recess 58, as a result of which the rotation of the turn 191 stops

of the company table 7 because of its lock

Opening the spool 54 also turns off the air motor 140, which causes the piston rod 139 to be pushed back and the slide 136 of the spool rod 133 forward relative to its average position in the valve body 121 against the action of the compressed air flowing through the piston. The following servo-mechanism connecting the spool 121 and the air motor 94 causes the air motor 94 to move the piston rod 95 forward in response to the forward movement of the spool rod 133. As a result of the forward movement of the air motor 94, the cross bar 93 of the working tool 92 and the block 96 together with the working tool move forward of the axis of the pins 86. As a result of this forward movement of the block 96, the linkage 130 rises, which leads to lowering of the cam 127 relative to the axis of the pin 128. When lowering the cam 127, the cam surface 126 moves away from In this case, the cam follower 125 together with the spool 121 moves forward following the outgoing cam surface 126 under the action of the spring 122 until the piston rod 133 is again in the middle position in the spool body 121, resulting in an air motor 94 stops the forward movement of the piston rod 95 and the working tool 92, and the working tool 92 is now in the initial extended position relative to the probe 142.

The opening of the spool 54 also causes the air motor 77 to engage, pushing the piston rod 79 back toward the protrusion 80, as a result of which the fork 74 pivots down relative to the axis of the pins 76 and lowers the tooth 75 of the fork 74, returning to the position where their bases are again in the horizontal plane.

The opening of the spool 54 also includes a pneumatic clutch 27 connecting the rotating

2382920

gear sprocket 41 with shaft 24, as a result of which shaft 24 and gear 23 begin to rotate in the direction opposite to the direction in which J rotated earlier, in response to

turning on the pneumatic clutch 34. The gear 23, rotating, moves the toothed rack 22 together with the slide 2 and the top shoe of the shoe in the longitudinal direction relative to the working tool 92 so that the working tool 92 touches the side of the shoe top when the shoe of the shoe upper moves from the toe 15 to the heel relative to the working tool.

The top shoe is moving in the direction from toe to heel with respect to working tool 92 20 until the second finger 57 starts to interact with the lever 46, which intersects at this moment with the second finger 57, due to the fact that the first finger 56 came out of

25 contact with the lever 46 during the rotation of the shoe shoe. Contacting the first pin 56 with the lever 46 causes the cam 47 to open the slide 51 again.

As a result of this, the opening of the spool 51 of the pneumatic clutch 27 is switched off and the movement of the shoe top blank relative to the working tool is stopped. The machine elements are returned to a non-operating state and the work cycle is completed. After that, the top of the shoe with ruffled pulling edge is removed from the machine. By rotating the turntable 7

0 between the toothed rack 22 and the gear 23 must not be reciprocally moved so that the slider 2 remains stationary relative to the turntable 7. The engagement of the teeth of the rail 23 and

The 2 gears 23 are usually sufficient to prevent relative movement.

However, if necessary, the corresponding muft 27 or 34 can be

Q is included during one or the other of these rotations in order to rotate gear 23 in the direction preventing this relative movement.
