Thrust pad 175 is made so that its slanted "a" and "b" clearly come in the span of the rollers 52 and 53 earrings 47, as when you stop poloski 173 clamp the neutral position of earrings 47.Machine for applying processing solution on the skin works as follows.Before turning on the motors 71 and 72 perform the tuning node for finishing leather. In this case, the tub 35 to the specified fill level of the liquid 37, prednaznachen is 38 for the passage of steam or hot water, for heating coil 36, the neck 39 of the tank 35 by turning the valve 40 shall pass a given jet apprecilove fluid 37 and controlauto this position of the valve (not shown) with the lever 42 of the rotation mechanism 41. On the tank 35, the electromagnet 44 is disabled, why under the action of the spring 43 of the lever 42 is rotated to its original position, i.e. the position of overlap of the valve 40. At the entrance to the brackets 63 transporting shaft 80 (Fig. 4) rotate alternately in a predetermined direction adjusting screws 91 and 92, moving thereby the shaft 86 with the sleeves 96 and 97 along the guide rails 90 a slight distance corresponding to the pass apprecilove fluid on the shaft 80. Walls 99 and 100 of the adjusting bolts 103 and 104 are pressed with a small force to the shafts 80 and 86, through deduction from the lateral draining the fluid received in the accumulation zone during initial configuration of the access valve 40. The site for the final touches ready for work. Also, before you start implementing some setting in the car. On Polushka mechanism 173 169 clamp constantly adjust the necessary efforts compression spring 176 by svorachivaniya screw 177, with Playground 175 remains in a horizontal position.Then to recognize what ane 56 by turning the screw 69, then by turning the stop screw 114 carry out the adjustment of the gap between the top 80 and bottom 81 of the conveyor shafts. The gap is set according to the thickness of the thin material (leather). Similarly, the output also carry out adjustment of the force of the spring 68 by a screw 70, while the upper conveyor shaft 82 lies on the lower conveyor shaft 83. Earrings 47 are in a horizontal position (Fig.1) (i.e., neutral), together with the clamping shafts 78 and 79, while the clamping mechanism 169 captures this position thrust pad 175, which for its slanted "a" is in contact with the roller 52 and the bevel "b" roller 53 earrings 47. In this neutral position the pinch rollers are equally away from the polishing shafts 75 and 76, providing free passage of material through the channel of grinding. In the neutral position of the mechanism 169 clamp on the rail 18 is located at the center. The electromagnet 30 is disabled, electrodance 9 and 14 remain off under the action of the spring 31, the sleeve 25 on the shaft 23 is rotated to the left (Fig.5), and the pin 24 in the slot 28 can detect this situation, why stop 27 is rotated in the passage area of the lateral stop 167 rotation mechanism 152 and the stop 26 remains in side. On the rotation mechanism 152 ele is allocated to the neutral position with detent 164. Machine is ready for operation.Include the motors 71 and 72. The rotation of pulley 132 motor pulley 71 123 transfer belt 137 in the direction of rotation at a given speed counterclockwise, as shown in Fig.1, is transmitted to the polishing shaft 75. Simultaneously, the rotation of pulley 134 of the motor 72, the pulley 124 by a belt 138 in the direction of rotation with high speed clockwise to the second grinding shaft 76. However, the second pulley 133 motor 72 transmits the rotation of the pulley 136 in the same direction of rotation by means of a belt 139 gear 73. In turn, the sprocket gear 135 73 transmits the rotation of the sprocket 130 of the shaft 83 at the entrance, in the same direction of rotation through a chain drive 140, the rotation is transmitted to the transporting shaft 83, which through the gear 122 (Fig.5) and the gear 118 transmits rotation in the opposite direction along the shaft 82. However, the rotation of the shaft 83 through the sprocket the sprocket 131 128 by means of a chain drive 143 in the direction of clockwise rotation is transmitted to the clamping shaft 79. At the same time the presser shaft 79 through the sprocket sprocket 127 125 by means of a chain drive 141 rotate in the same direction according to the rotation system-easy installation is the conversion in the same direction of rotation of the transporting shaft 81 at the entrance, through the gear 120 and the gear shaft 115 81 transmits rotation in the reverse direction conveying namasivayam shaft 80, which is starting to rotate through gears 116 and 98 transmits rotation in the direction of movement in the opposite direction the shaft 86. During mutual rotation of the shafts 80 and 86 and subject to the controlled clearance between the shaft 80 is in fluid film thickness, according to the regulation. So, without further stops above the transporting shaft 80, polishing the shaft 75 and the transporting shaft 82 at the output have the same rotation direction counter-clockwise, and polishing the shaft 76 rotation direction clockwise. Respectively on the bottom of the entrance conveying shaft 81, pinch rollers 78 and 79, as well as transporting the shaft 83 at the output of all received the same rotation direction clockwise. When the shaft 83 through the axis 122 is transmitted to the rotation drive mechanism 153 152. The disc 152 through the connecting rod 155 moves the rod 157 in the cavity 160 of the housing 159 in a reciprocating motion, in this case 159 remains stationary in the middle position and is held by a gear 172 which engages with the toothed rails 162 and treatment 22 in the neutral position to rotate the earrings. The machine is ready to process the different length of the material greasing the front side of the skin apprecilove fluid and subsequent polishing, in order to avoid stains on the Shine.Processing normal length saddle-cloth of the skin is performed without setting the neutral position of earrings 47 with clamping shafts 78 and 79, and the short length of the skin, such as a crank, pieces and so on is handled with automatic installation the neutral position of the Chuck shafts 78 and 79. The skin is of smaller length than the saddle-cloth is processed on the machine as follows. Take the skin 8 and placed face down on table 7, moving at the entrance under the first pair of shafts 80 and 81, and the skin 8 on the table 7 is in contact with electrodata 9, which simultaneously gives the command to activate the electromagnet 44 of the mechanism 41 of the rotation of the crane, the electromagnet 30 of the switching mechanism 22 and the electromagnet 168 rotation mechanism 152. Under the action of an electromagnet 44, overcoming the force of the spring 43, the lever 42 is rotated from the source to the working position by rotation of the valve 40, opening the passage apprecilove fluid 37 from the bath 35 on the pipe 39 in the accumulation zone (Fig. 4) between the rotating shafts 80 and 86, while pure and below the top 80 of the shaft skin to become transported towards the polishing shaft 75 and simultaneously applied aprettywoman liquid 37, the lower rubber shaft under the pressure of the spring 67 presses rough skin to smooth shaft 80, providing a uniform impregnation of the skin along the entire length. From beginning to end promazyvanija skin the valve 40 is opened, so that the skin 8 continues to have contact with electrodata 9. At the same time when the electromagnet 30 under the action of the spring 31, the sleeve 25 on the rod 23 of the switching mechanism 22 is rotated to the left (Fig. 5), and the pin 24 in the slot of the sleeve 25 can detect this situation, why stop 27 is rotated in the passage area of the lateral stop 167 rotation mechanism 152 and the stop 26 remains in side. When the electromagnet 168 rotation mechanism 152 disk 153 continues to rotate together with the shaft 83 and move through the connecting rod 155 in the reciprocating movement of the piston rod 157 in the cavity 160 of the housing 159, which is held in position corresponding to the neutral position of earrings 37 (Fig.1). When the drive rod 153 155 together with the rod 17 is at top dead center and starts to fall towards the bottom dead point, the rotation mechanism 152 under the action of solenoid 168, overcoming the spring force, the lever 165 is rotated into the operating position by moving the latch 164 in the hole 163 in the direction of the rod 157. the I electromagnet 168 head enters the groove 158. At this point the rod 157 on the disk 153 is located at the middle position of the moving fixed on the housing 159 and continues to move toward the bottom dead point. Thus, with this moment together with the rod 157 starts to fall casing 159 with gear rack 162, which, interacting with the gear 172 rotates it in a given direction, while the gear 172 is in engagement with gear rack 170, moving it in the sleeve 19 together with poloskei 173 along the guide 18 to the left, i.e., forward position in the direction of installation of the roller 52 on the ring 47. Polushka 173 resistant Playground slant "and" acts on the roller 52 and sets its equal place under the roller thereby effecting rotation of earrings 47 with the shaft 45 in the sleeve 33, together with the clamping shafts 78 and 79 in the position shown in Fig.2. In this case, when turning the earrings 47 presser shaft 78 is lifted in the direction of the polishing shaft 75, and the pressure roller 79 is lowered relative to the polishing shaft 76, as additional balance due to the displacement axis of the shaft 45. At this point the skin 8, passing through the conveyor 80 and Promisory 81 shafts, respectively rests on the guide plate 146 and is supplied to the pressure balm to polishing the shaft 75. When moving down the body 159 with gear rack 162 on prijemnom the lever 165 side emphasis 167 reaches the installation of the stop 27 is rotated in a zone of contact with the sleeve 25 and the electromagnet 30 continues to be disabled. When interacting side stops 167 articulated emphasis 127 lever 165 is rotated to its original position, deriving from the groove 158 of the latch 164 and its spring captures this position, after which the casing 159 remains in a predetermined position, and the rod 157 from this moment until the next commit moves on air in the cavity 160. Thus, lifting of the clamping shaft 78 is completed. Leather 8 continues to be processed in two operations at the same time finishing and polishing (Fig.2) until the second end of the short skin ceases to communicate with electrodata 9 in table 7. At this point the installation is performed earrings 47 together with the clamping shaft in a neutral position according to Fig.1, and turn off the electromagnet 44, the rotation mechanism of the valve 40. Under the action of the spring 43 of the lever 42 with the valve 40 is rotated to its original position, i.e. in the direction of closing the valve, why aprettywoman liquid ceases to act on the shafts 80 and 86 in the accumulation zone. Installing earrings 47 stops, which, overcoming the force of spring 31, rotates the sleeve 25 on the shaft 23 in the opposite direction, i.e., puts a stop 26 in the zone of the lateral stop 167.However, is turned on and the solenoid 168 of the rotation mechanism 152, which, again overcoming a spring force, rotates the lever 165 in its working position, and at the time of coincidence of the groove 158 with the location of the latch 164 provides fixation of the stem 157 housing 159 due to hit the head of the latch 164 in the groove 158. When moving toward the bottom dead point and the toothed rack 162 through the gear 172 moves in the opposite direction which is in engagement with it the rack 170 together with poloskei 173 from the extreme front position in the direction opposite its original position, i.e., moves the thrust pad 175 from under the roller 52 under the roller 53 on the ear-rings 47. However, in the process of moving an interrupt occurs, because the side emphasis 167 reaches the zone installation rotated the stop 26, communicates with him via a lever 165 outputs the latch 164 of the groove 158 of the shaft 157, and the stock continues to move up to the bottom dead point. In the specified moment resistant space 175 rotates in the opposite direction earrings 47 due to the vanishing of the roller 52, while the thrust area is Rigi 47 take the horizontal, i.e., the neutral position according to the position of Fig.1. At this point the skin 8, the processed lubrication and polished the first half, coming out of the rear end out from under the shafts 80 and 81, moving along the guide 146 and the pressure roller 79 and forth on the guide rail 141, and then the transporting rollers 82 and 83 at the output of the treated surface and, when the table 13, immediately comes into contact with electrodata 14, which gives the command to turn off the electromagnet 30 to the switching mechanism 22. Under the action of the spring 31, the sleeve 25 on the shaft 23 is rotated to the left, i.e., the stop 27 is rotated in the zone of the lateral stop 167. However, also turns the electromagnet 168, which rotates the lever 165 in working position with the latch 164. Upon further movement of the rod 157 is at top dead center toward the bottom dead point and back to the moment when the groove 158 will be in the area of location of the latch 164, the latter of which is in the groove 158, through the next fixation rod 157 in the housing 159, after which the rod 157 together with the housing 159 and gear rack 162 is moved from the lower extreme position to the upper stop position. When moving the housing 159 and the toothed rack 162, interacting with the gear 172 in reverse naprej 173 from the neutral position to the rightmost position, i.e., in the position according to Fig. 3. While the bevel b of the thrust pad 175 is in contact with the roller 53, and then his plane comes under the roller 53. At a specified point in case 159 rose to its highest position, with the free end of the lever 165 is in contact with the stop 17 on the frame, is rotated to the neutral position, thus moving the latch 165 of the grooves 158, solenoid 168 is disconnected (not shown). At this point the skin 8 continues to be transported polished treated plot shafts 82 and 83, and is not processed by the polishing section is the bottom before the second polishing shaft 76 and touching it until a full treatment of the second half of the skin on the aisle. After completion of processing leather 8 polishing shaft 76 passes through the area of installation transporting the shafts 82 and 83 and the table 13 is supplied to the passage, for example for packing (not shown). The skin 8 output passes through the contact zone with electrodata 14. In the absence of contact with electromachine 9 and 14 automatically on the above described sequence is set to the neutral position earring 47 together with the clamping shafts 78 and 79. Skin treatment normal size (saddle-cloth) is identical in the above sequence that is in the process of processing leather 8 without interruption in series along the first contact with electrodata 9 on the table 7 at the entrance, and then electrodata 14 on the table 13 at the output.
