0 is placed mandrel 148 for winding the assembled conveyor, on which cables 149 with grippers are fastened

150. Assembled product: bar

151, plate 152.

5 Lini works as follows.

The plates 152 of the vibrating hoppers 1 through the trays 2 are fed to the assembly device 8 and fall into the sockets 48 of the stops 41 in a vertical position.

0 Manually, at the initial moment of operation of the line, install the centering mandrel 107 (hereinafter, the mandrel is fed automatically) into the guide 83 of the bar feed mechanism 16. The Start button located on the control panel (not shown) is turned on. The rods 151 from a special tare box come into the mechanized bunker 17, In this case the agitator 95 using si

0 of the left cylinder 93 performs the turning of the bars 151, causing the latter to fall into the broken grooves formed by the plates 106, the Bar 151 ,. imprisoned between dog lips

5, 100 with end walls of the cut-offs 98, driven by the cylinder 93, is fed to the assembly area. At the end of the stroke of the cutters 98, the pins 101 sliding along the copiers 102 are lowered and

0 dogs 100 release the bar, which pbL4 along the ramp 84 falls into the guide 83. The power cylinder 91 uses the lever 90 to move the carriage 86, which moves the pusher 89. The last bar moves the bar 151 in the direction of the plates 152, and the bar, in turn, pushes in front of itself the centering mandrel 107, which

centers the plates 152 over the hole

When the centering element 107 of the platinum clamp mechanism 11 passes by, the power cylinder 30 moves the rod of which moves downward and, with the aid of the pulling rod 28, moves the outer clamps 27, fixing the 151 oriented through the hole of the plate. After the mandrel 107, the bar 151 passes through the holes in the plates 152 The centrifugal mandrel 107 enters the grip 116 of the mechanism 19 for displacing the mandrel and interacts with the limit switch 60, which turns on the lifting mechanism 13, and the power cylinder 42 lowers the stops 41.

In addition, the signal from the limit switch 60 is fed to a counting-pulse relay (not shown), which measures the total length of the conveyor belt being assembled, and at the same time commands the idling of the steamer 15. The actuator 30 actuates, the rod moves upwards and spreads the outer clamps 27, which push the inner clips 26 apart, the plates 152 unclamp, and they hang on the bars 151. When the clips are maximally divergent, when the bars 28 take a horizontal position, the inner clips 26 displace the plates 152 into the grooves 151. Fixation of the rods 151 is provided by prismatic grooves of the L-shaped clamp 39, which presses the rods in the assembly zone. A spring 35 installed inside the stem 32, a bottom end through the lower support 36 and a retaining ring 38 acts on the rod 32. The upper end of the spring 35 acts through the upper support 34 and the pin 37 on the housing 31, thereby providing a constant force that guides the rod down. and, therefore, the constant pressing of the rod and its orientation in the prismatic grooves of the L-shaped clamp 39.

When the conveyor 15 is idling, the movable rods 63 with dogs through the cylinder 65 move the crawler 115 with the grip 116 and the centrifugal mandrel 107 in it with the aid of the rocker arm 118. At the end of the travel of the slider 115 the centering mandrel 107 falls into the groove on the plate

centering mandrel 107. On command from end switch 60, carriage 86 moves to its original position, stops 87 against clamp 113 and moves closed cable 111, raising the slider 109 with bar 110 and centering mandrel 107 on the bar. the centering mandrel 107 over the ramp 84 rolls down into the guide 83. Then the power cylinder 65 makes a working stroke and through the arms 66 and the legs 69 moves the movable rods 63 with the pawls 72. The latter take the rods 151 and move the assembled conveyor one step. When this movable rod 63 through the beam 118 returns the slider 115 with the seizure 116 of the original position.

When moving the assembled conveyor to a step, the roller 51 of the counting mechanism 14 of the controlled conveyor length, interacting with the rod 151 of the assembled conveyor, turns the limit switch 53 by means of a spring-loaded pusher 50 and the cam 52. The signal from the limit switch is fed to the pulse-counting relay. Stationary rod 61 with dogs 62 fix the position of the collected conveyor when idle movable rod 63.

After the end of the working stroke of the step conveyor 15, the lugs 41 of the lug lift mechanism 13 are raised and the plates 152 are delivered to the assembly area by cutters 3. The assembly cycle of the conveyor link is over.

When the controlled length of the collected conveyor is counted, the length counting mechanism 14 gives a signal for fixing the assembled conveyor. The power cylinder 77 is turned on and the middle 76 and levers 78 are raised in the guide bushings 74 of the slider 75, providing a rigid fixation of the assembled conveyor during its testing for strength, elongation and misalignment of the branches using the assembly quality control mechanism 21. The power cylinder 124 by means of the earring 122 and the lever 123 moves the slider 125. At the same time, the pawls 128 pivotally mounted on the rocker arm 127 capture the bar 151 and transfer the predetermined load created by the power cylinder 124 to the assembled product.

this load limit switch 126 controls the allowable elongation of the conveyor. Limit switches 129 control the permissible misalignment of the conveyor branches. At different lengths of the branches of the assembled product, the yoke 127 rotates about the axis and when the branches are more distorted, the one of the limit switches 129 turns on. A signal about the presence of a defect is transmitted to a control panel (not shown). At a time relay signal (not shown), the assembly quality control mechschism 21 returns to its original position. Simultaneously with the control of the assembled product, a trace is assembled in the assembly zone on the assembly device 8: a polished link.

The separation of the assembled conveyors of a given length is carried out as follows.

When the end switch 60 counts the total length of the conveyor, it sends a signal to prohibit bar 151 (the power cylinder 91 is not turned on), which ensures the separation of the previous conveyor from the subsequent one when the line is operating continuously. The reset of the counting from the counting-relay relay, counting the total length of the conveyor to be assembled, is effected by a signal from the limit switch 40 of the bar-presser mechanism 12. The absence of the bar 151 under the clamp 39 allows the rod 32 under

the action of the spring 35 is lowered down and using the lower support 36 to turn on the limit switch 40, the winding of the assembled conveyor is carried out by a winding mechanism 23, on the roller prisms 139 of which the mandrel 148 is installed up to the stop 140, the clamps 150 fixed on the cables 149 capture the first bar of the assembled product . Manually move the quill 147 to the bottom with the mandrel 148. The drive 141 is turned on, which transmits rotation from the engine 142 through the gearbox 143 and the chain drive 144 to the shaft 145 "The control of the winding of the assembled conveyor is carried out by the control mechanism 22, the collecting conveyor at the stepping slides along the slopes 133, rigidly connected to the shaft 131. The slopes 133 balance the levers 134 with the counterweights 135. When the slopes 133 are lowered under the assembled conveyor belt, the cam 136 turns on the limit switch 137, the signal from which goes to drive 141. When the assembled product is tensioned, the chutes 133 rise, the end switch 137 turns off the drive 141, the table 138 is rotated by 90, and the mandrel 148 with the coiled product is withdrawn from the winding zone, then the assembled product with the mandrel 148 is removed and transported to place of assembly of machines, t-shi storage.
