Rake 42 attachment0

The frame 55, on which are also mounted the mechanisms allowing to synchronize the operation of the device.

Thus, the frame 55 is connected to a rod 57 having a dog 58 for engaging with the shelf 4 in the loading zone thereof. In addition, a cam 59 is attached to the frame 55, which is operable to interact with an L-shaped lever 60 mounted on the latch 61 of the two shoulders 62, one arm of which has the ability to interact with the pushrods 63 of the feed 3 and the outlet 7 sections of the conveyor system and the other with a latch 61. The conveying elements of the discharge section 7 have the ability to slip, while non-driving roller tables 64 and 65, respectively, are mounted in the supply areas of untreated 4 and clean 5 shelves.

The rotary mechanism 11 has the possibility of a stepped rotation of 180 °, with the angle os from the forced rotation mechanism 31 and the angle (180 ° C) from its self-rotation. A centrifugal speed limiter 66 is provided for adjusting the self-rotating speed of the mechanism 11.

The device performs the following periodic operations during one turning cycle: I - forced turning of the rotary mechanism 11 by the angle ot; II - self-rotation mechanism II

The second angle is the accumulation of O both potential and kinematic

energy. First, the turning mechanism 11, together with the weight (shelf 4 and cheese heads 1), rises from a horizontal position to a vertical position, in. second, the rotated body has inertia, which contributes to maintaining its speed.

Thus, in the upper position, the mechanism 11 has the amount of stored energy for performing the subsequent operations. Ratchet in this position

20, the wheel is freed from the interaction of the pawl 34 due to the speed difference, and the roller 50 engages the protrusion 44 and begins to rotate the lever 33. This starts the second operation. The speed of self-rotation of mej, Khanizm II, is adjusted with the help of limiter 66. When rotated (180-ot), roller 45 first rolls around the circumference according to the radius of the circular sector 48, and at the end of the cycle, due to the presence of the string 51, changes trajectory.

energy output, i.e., to carry out a 25 V operation. At the end of the feed 3 sections of the conveyor system.

The sequence of these operations is carried out according to the sequence diagram of the device (Fig. 9). Before the start of operation I, all the mechanisms take their initial positions, i.e., raw shelf 4 is in the loading area between the gripping mechanism 18 and the lower transporting body 17, the fixture 25 receiving and removing the shelves bearing the dangerous shelf 8, the rotary mechanism 11 occupies the extreme positions, and they are shifted towards the axes 13 and 14. The rotary mechanism 11 is reported to have a forced rotary motion at an angle ot. In this case, the lever 33 by means of the pneumatic cylinder 32 is rotated through the angle OS, as a result of which the dog 34 drives the semi-axis 14.

At the beginning of turning, the gripping mechanism 18 lifts shelf 4 from the feeding section 2, after rotating the mechanism I1 at some angle, the compressed air moment of the self-rotating mechanism 11 Q rotates the upper roller 50 of the unloaded transport body 17 through the self-lifting bridge 52, which passes through the linear sector 49, and the pneumatic chamber 23 through the hose 26, channels 27 and 29 communicates with the atmosphere.

During the execution of the I operation, the III operation is also performed, and during the implementation of the II operation, the IV operation is also carried out. Its sequence is carried out in the following order. The rotating market 55 step 36 by means of the cable block system 37 of the cone-shaped drum 38 and the counterweight 39 causes the shaft 40 to rotate, the wheel 41 of which converts the rotational

ha through channels 27, the hose 26 communicates with the pneumatic chamber 23 of the lower (loaded) transporting body 17, which, inflating, presses the heads of the cheese

I shelf 4 to preserve their initial placement during roll over. In order to fix the position of the carriage 16, the roller 50 engages with the circular sector 47 of the guide 46. When the mechanism is turned

The second angle is the accumulation of O both potential and kinematic

energy. First, the turning mechanism 11 together with the load (shelf 4 and cheese heads 1) rises from a horizontal position to a vertical position, and secondly, the rotating body has inertia, which contributes to maintaining its speed.

Thus, in the upper position, the mechanism 11 has the amount of stored energy for performing the subsequent operations. Ratchet in this position

0, the wheel, due to the speed difference, is released from the engagement of the pawl 34, and the roller 50 engages with the protrusion 44 and begins to rotate the lever 33. With this, the II operation begins. The self-spinning speed, khanizm II, is adjusted with the help of the limiter 66. When rotated (180-ot), the roller 45 first rolls around the circumference according to the radius of the circular sector 48, and at the end of the cycle, due to the presence of the string 51, changes the trajectory.

the drive 24 is released from the interaction of the rotary mechanism 11, which at the same time takes a horizontal position, further maintained due to the support of the roller 50 on the straight sector 49

The moment of self-rotating mechanism 11, the upper roller 50 of the unloaded transport body 17, through the presence of a self-lifting bridge 52, passes through the straight sector 49, and the pneumatic chamber 23 through the hose 26, channels 27 and 29 communicates with the atmosphere.

0, the end of operation II ends the turning of the cheese heads. In contrast to the initial situation, the heads of the cheese 1 are located on the supporting element 19 of the upper conveyor body 17, and on them there is a sign of the regiment 8.

During the execution of the I operation, the III operation is also performed, and during the implementation of the II operation, the IV operation is also carried out. Its sequence is carried out in the following order. The rotating lever 36, using the cable-block system 37 of the cone-shaped drum 38 and the counterweight 39, rotates the shaft 40, the wheel 41 of which converts the rotational

the movement in the translational movement of the rail 42, and thus the device 25 to the right (Fig. 1). When moving the device 25, the dog 58 engages with the shelf 4 and leads it to move to the loading area, while the roller forks 53 move the dirty shelf 8 towards the discharge section 6. As the roller forks are mounted with the possibility of embracing section 6 and below the carrying surface, the shelf 8 automatically moves as the forks 53 and section 6 shifts onto the latter.

The achievement of the extreme right position by means of the device 25 coincides with the moment when the turning mechanism 11 moves to a horizontal position. This device is ready for V operation. During the forced rotation of the lever 36 by means of the cable-block system 37 and the cone-shaped drum 38, the counterweight 39 rises, which thereby accumulates the potential energy for moving the device 25 in order to carry out the V operation. As soon as the lever 36 is freed from the action of the mechanism 11, the gravitational force of the counterweight 39 begins to rotate the shaft 40 with the wheel 41 counterclockwise (Fig. 1).

Brackets 54 and forks 53 are driven into motion by means of a rail 42. In this case, brackets 54 engage with the upper gripping mechanism 18 and drive the carriage 16 together with the nodes of the upper and lower transport body 17 attached to it.

Moving the carriage 16 helps to reduce the length of the upper transporting body 17 and increase the length of the lower one. When moving the carriage 16, the relative length of the loops of the carrier element 19 changes. Since the ends of the latter are fixed to the frame 12 of the rotary mechanism 11, the end portion of the carrier element 19 is fixed during this movement of the carriage 16 with respect to the cheese heads 1 being shifted, and therefore it seems to run away from under the cheese heads 1, which are shifted to a clean shelf 5. The transfer of the cheese heads 1 is completed s when kronschteyny 54 m carry one stroke, t. e. when the counterweight 39 opustits down while the lever 36 takes its original upright position. During this movement, the roller forks 53 enter the space between the heads of the cheese 1 and the shelf 8, and

the movements of the fork 53 remove the latter from the heads of the cheese 1, gradually shifting to themselves, i.e. the second part V of the operation is carried out.

At the end moment of movement of the device 25, its cam 59 acts on the lever 60, disengages the latch 61 and releases the two shoulders lever 62. These pushers 63 of the carrier element of the sections 3 and 7 of the conveyor system are released from braking and the shelves start moving, and the shelf 9 is taken out from the transmission zone, and the blank shelf 5 is fed to this zone.

So by pushing the cam 59

the IV operation begins, and after it the III operation. Pushers 63 have the ability to move one step. This is because the cam 59 detaches the latch 61 only when moving to the left, i.e. as it interacts with the lever 60, first turns the latter until it engages with the latch 61, then rotates the lever 60 together with the latch 61, then the latch is released from cam 59 and returns to its original position before fixing

the two shoulders of the lever 62. When the cam 59 returns, the lever 60 deflects freely without interacting with the latch 61.

The device is ready to repeat the above described operations of another cycle.

The proposed design provides process optimization in relation to the operations performed, as well as the resulting static and dynamic loads. During the rotation of the device, primary and secondary energy is accumulated: the accumulated potential and kinematic energy when the rotary mechanism 11 is rotated through an angle from 0 to 90 ° is used for conducting. N operations; the amount of energy available during self-rotation of the device in the range from 90 to 180 ° is converted into work for performing IV operation and raising the counterweight, which consequently accumulates secondary energy for performing I and VI operations. In this case, the proposed device provides a balance of static and dynamic loads. This is facilitated by the supply of a drive that has the ability to accumulate energy, and its design, ensuring the conversion of stored energy into useful work, and making the drum cone-shaped, contributing to the balancing of forces both during accumulation and in energy release.
