In addition, the rotation mechanism 112 is equipped with a housing 120 having a cavity 121, the bracket 122 and the trailing portion 123, made in the form of a toothed rack that is installed vertically lower end of the sleeve 20 with the return is positive displacement. On the upper housing 120 is made a hole 124 in which is placed one end of the rod retainer 125, incoming at a given point in the groove 118 and connected to the second end with two shoulders lever 126, through which the axis 127 pivotally mounted housing 120, provided with a lateral stop 128 by spring 129 double action, two locking position two shoulders of the lever 126 is neutral and the locking position. The free end of the two shoulders of the lever 126 is in contact with the stop 17 at the upper position of the housing 120, and a lateral stop 128 is in contact on the job with the lugs 26 and 27 of the mechanism 22 of the switch during movement of the housing 120, which has not reached the lower position, providing the output of the latch 125 with grooves 118 on the shaft 117. To ensure rotation of the two shoulders of the lever 126 in the locking position of the latter is connected with a spring 129 double action and the electromagnet 130, fixed to the body 120 of the bracket 122 and electrically connected to electromachine 9 and 14, mounted on the table 7 and 13 respectively. In addition, the rotation mechanism 112 is connected with the clamping mechanism 131 of the shafts 67 and 68, which is provided with a gear rack 132 installed horizontally in the sleeve 19 mounted on the lower horizontal rack 4. At the junction of the side pestom axis 133, fastened to the frame (hardware not shown), has a wide gear 134, one part of which is in engagement with the teeth of the rack 123, and the second part with the teeth of the rack 132, thus providing movement in a horizontal plane in a reciprocating movement poloski 135 the guide plate 18 in turn, the roller 42 under the roller 43 earrings 37, respectively. On Polushka mechanism 135 131 clamp through the axis 136 pivotally mounted thrust Playground 137 beveled "a" and "b". Inside support area 137 spring-loaded up the hard spring 138, one end of which abuts against pultusku 135, and the other in the thrust pad 137. To limit the compression spring 138 on Polushka 135 has an adjusting screw 139, the lower end of which rests against the spring 138.Hard Polushka 137 are made so that when the horizontal position earring 37 (see Fig.1) on the thrust pad 137 bevel and applies roller 42 and the bevel b of the roller 43, being thus in the course when you stop poloski 135 lock earrings 37 in the neutral position.Machine for machining skin works as follows.Before turning on the motors 61 and 62 on Polushka 135 mechanism regulirovanie screw 139, when this thrust area 137 remains in a horizontal position. Then at the entrance carry out the adjustment of the given force pressing the upper conveyor shaft 69 to the lower shaft 70 by svorachivaniya adjusting screw 59, the shaft 69 applies shaft 70. Then similarly, at the output are also adjusting the force of the spring 58 compression by svorachivaniya screw 60. Before the start position of the machine corresponds to the position shown in Fig.1. In this case, earrings 37 are in a horizontal position, i.e., neutral with clamping shafts 67 and 68, the clamping mechanism 131 can detect this situation thrust pad 137, which slanted "a" is in contact with the roller 42 and the bevel "b" movie 43 earrings 37. In this neutral position the pinch rollers 67 and 68 are at the same a considerable distance from the blade shafts 64 and 65, respectively, providing free passage through the channel processing of any material, in this case the skin 8. In the neutral position, the clamping mechanism 131 on the guide plate 18 is centered with respect to the source and at the moving point of poloski 135.The electromagnet 30 is disabled, because the machine is not enabled, electrodance 9 and 14 in table 25 on the rod 28 is rotated to the left (see Fig.5), and the pin 24 in the slot 28 of the sleeve 25 can detect this situation, from which the stop 27 is rotated in the passage area of the lateral stop 128 of the rotation mechanism 112 and the stop 26 stays away from the passageway side of the stop 128. On the mechanism 112 turning the electromagnet 130 is also disabled.Two shoulders lever 126 on the housing 120 under the action of the spring 129 double action fixed in the allotted neutral position together with the retainer 125. Machine is ready for operation. Include the electric motors 61 and 62. The rotation from the pulley of the motor 61 is transmitted to the pulley 81 by a belt 95 in the direction of rotation counterclockwise (as shown in Fig.1) the knife shaft 64. At the same time from the pulley 92 of the motor 62 to the pulley 82 by a belt 96 in the direction of clockwise rotation is transmitted to the second knife shaft 65. However, the second pulley 91 of the motor 62 to the pulley 94 in the same direction of rotation passes through the belt 97 of the gear 63. In turn, the sprocket gear 93 63 sprocket 88 of the shaft 72 at the output in the same direction of rotation through a belt drive 98 passes transporting shaft 72. However, the rotation of the shaft 72 through the sprocket 89 sprocket 86 by means of a chain drive 102 in the direction of rotation clockwise clamping shaft 68 through the sprocket the sprocket 85 83 by means of a chain 99 rotation in the same direction according to the rotation of the shaft 68 is transmitted to the clamping shaft 67. The presser shaft 67 through the sprocket 84 by means of a chain drive 100 transmits rotation in the same direction of the lower conveyor shaft 70 at the entrance. The upper shaft 69, lying on the lower shaft 70 starts to rotate in the reverse direction relative to the shaft 70. Accordingly, the output of the upper conveyor shaft 71, lying on the lower shaft 72 also rotates in the reverse rotation direction counterclockwise with respect to the lower shaft 72. So, without further stops above the transporting shaft 69 at the entrance, knife shaft 64 and the transporting shaft 71 at the output have the same rotation direction counter-clockwise, and the knife shaft 65 has received rotation in the direction of clockwise. Respectively on the bottom of the entrance conveying shaft 70, pinch rollers 67 and 68 also transporting the shaft 72 at the output received is identical to the rotation direction clockwise. When the shaft 72 through the axis 80 is transmitted to the rotation of the disk 113 of the rotation mechanism 112. The disk 113 through the connecting rod 115 moves the rod 117 in the housing cavity 120 in a reciprocating motion, in this case 120 remains stationary in the middle position and held pore of the clamping mechanism 131.When the machine is switched on, the electromagnet 30 is enabled by setting mechanism 22 of the switch in the neutral position to rotate earrings 37. Machine is ready for operation and can miss in a row without sorting lengthy skin 8 (in this case the saddle-cloth) or along the length of the small skin (for example, tap wrenches, and so on).Compact leather is processed on a machine with regard to automatic installation of earrings with 37 clamping shafts 67 and 68 in the neutral position, and the normal length leather is processed by the machine without installing the neutral position of earrings 37.Compact leather is processed on the machine as follows. Take the skin 8 and put it on the table 7, moving at the entrance under the first pair of rotating conveying shafts 69 and 70, and the skin 8 on the table 7 is in contact with electrodata 9, which gives the command to switch on the electromagnet 30 to the switching mechanism 22 and the electromagnet 130 rotation mechanism 112.Under the action of the spring 31, the sleeve 25 on the rod 23 of the switching mechanism 22 is rotated to the left (see Fig.5), and the pin 24 in the slot 28 of the sleeve 25 can detect this situation, therefore, the stop 27 is rotated in the passage area of the lateral stop mechanism 128 to pavarottis together with the shaft 72 and to move through the connecting rod 115 in the reciprocating movement of the rod 117 in the housing 120, which is held in position corresponding to the neutral position of earrings 37 (see Fig.1). When the drive rod 113 115 together with the rod 117 is at top dead center and starts to fall towards the bottom dead point, the rotation mechanism 112 under the action of the solenoid 130, overcoming the force of spring 129, the two shoulders, the lever 126 is rotated into the operating position by moving the latch 125 in the hole 124 in the direction of the rod 117. When the rod groove 117 118 will be in the area of location of the retainer 125, the latter under the force of the electromagnet 130 head is in the groove 118. To the specified torque (see Fig. 1) the rod 117 on the disk 113 is located at the middle position move together with the already fixed on the housing 120 and continues to move toward the bottom dead point. Thus, with this moment together with the rod 117 starts to fall the housing 120 with the rack 123, which, interacting with the gear 134 rotates it in a given direction, while the gear 134, being in engagement with gear rack 132, moves it into the sleeve 19 together with poloskei 135 along the guide 18 to the left, i.e. in the forward position in the direction of the installation roller 42 on the ring 37. At poluchistsya thus rotate earrings 37 with the shaft 35 in the sleeve 33, together with the clamping shafts 67 and 68 in position, it is shown in Fig.2. In this case, when turning the earrings 37 presser shaft 67 rises toward the knife shaft 64 and the pressure roller 68 is lowered relative to the knife shaft 65, as ballast by mixing axis. At this point the skin 8 is supplied under the transporting rollers 69 and 70, rests on the guide plate 105 and is supplied to the pressure roller 67, which in this initial moment, and carries out the pressing of the skin for treatment with the specified force to the knife shaft 64. When moving down the body 120 with the rack 123 on the two shoulders of the lever 126 side stop 128 reaches the installation stops 27, tapped at the zone of contact spring 31 together with the sleeve 25 and the electromagnet 30 continues to be disabled. When interacting side stops 128 articulated emphasis two shoulders 27 of the lever 126 is rotated to its original position, deriving from the groove 118 of the retainer 125 and the spring 129 captures this position, after which the housing 120 remains in a predetermined position, and the rod 117 from this moment until the next commit is moved to idle. Thus, lifting of the clamping shaft 67 is completed. Leather 8 continues to be processed first blade shaft 64, pressed the holding shaft 67, as shown in Fig.2, until the second end of the short leather 7 together with the clamping shaft in a neutral position according to the position of Fig.1.Turns on the electromagnet 30 of the switching mechanism 22, 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 stops 128. However, turns on the electromagnet 120 rotation mechanism 112, which, again overcoming the force of spring 129 on the housing 120, rotates the lever 126 into position and at the time of coincidence of the groove 118 with the location of the retainer 125 provides fixation of the stem 117 of the housing 120 through the contact head retainer 125 in the groove 118. When moving toward the bottom dead point and the toothed rack 123 through the gear 134 moves in the opposite direction which is in engagement with it the rack 132 together with poloskei 135 from the extreme anterior position to the rearmost position (the original), i.e., moves the thrust pad 137 from under the roller 42 under the roller 43 on the ear-rings 37. However, in the process of moving side stop 128 reaches the zone turned the stop 26, communicates with him via a lever 126 outputs the latch 125 of the grooves 118 on the shaft 117 and the stock continues to move up to the bottom dead point. In the specified moment resistant space 137, turning earrings 37 due to the vanishing of the roller 42, rotates poslednom "and" again in contact with the roller 42, and the bevel b is in contact with the roller 43, making earrings 37 take the horizontal, i.e., the neutral position (see Fig.1). At this point the skin 8, processed in half along the length, enters the rear end out from under the conveyor shafts 69 and 70, moving along the guide 105, enters the guide 106 and the pressure roller 68 and forth on the guide rail 111, and then the conveying rollers 71 and 72 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 stops 128. However, also turns the electromagnet 130, which rotates the lever 126 in the operating position with the latch 125. Upon further movement of the piston rod 117 of the top dead center toward the bottom dead point and back to the moment when the groove 118 will be in the area of location of the retainer 125, the latter of which is in the groove 118, creating yet another fixing rod 117 in the housing 120, after which the rod 117 together with the housing 120 and the rack 123 is moved from the lower extreme position to the upper stop put to the supports of the latter, which, interacting with the gear rack 132, moves it together with poloskei 135 from the neutral position to the rightmost position, i.e. in the position shown in Fig.3. While the bevel b of the thrust pad 137 is in contact with the roller 43, and then his plane comes under the roller 43. At a specified point in the casing 120 is raised to its highest position, with the free end of the two shoulders of the lever 126 is in contact with the stop 17 on the frame 1 of the rack 3, is rotated to the neutral position, thus moving the latch 125 of the grooves 118, the solenoid 130 is turned off (not shown). At this point the skin 8 continues to transport the treated surface shafts 71 and 72, and not treated area is below the second blade shaft 65 and is pressed against the knife shaft 65 to complete processing of the second half of the skin 8. After skin treatment 8 blade shaft 65 passes last zone setup conveying shafts 71 and 72 and the table 13 is output, for example on styling (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 of earrings 37 together with the clip is sledovatelnot with the only difference being when processed this skin, do not set the neutral position of earrings is 37, because in the process of normal length (saddle-cloth) leather 8 without interruption consecutively during processing is in contact with the first electrodata 9 on the table 7 at the entrance, and then electrodata 14 on the table 13 at the output. After processing the previous skin 8 handle another skin on the above described sequence.The effect of the invention is to increase the technological capabilities due to the fact that the machine provides automatic installation of the clamping shafts with earrings in neutral position and it became possible to pass through the machine without any setups small length and large skin, as well as increased reliability of operation of the machine, since the neutral position eliminates the capture knives freely passing under the blade shafts of the skin.
