    A machine for cutting up lumps of crude rubber (synthetic or natural) and weighing out an accurate quantity to be fed to a mixer in accordance with a selected formula, comprising two band saws having special blades with teeth having no "set" and lying entirely within the plane of the blades; crude rubber blocks are fed to a first of two band saws on two conveyor belts which pass one to either side thereof, one of the two conveyors being laterally displaceable and able to convey one of the portions into which the block of crude rubber is cut by the first band saw to be cut by the second band saw, the lateral position to which this portion is conveyed determining the relative size and therefore weight of the two pieces into which this portion is cut; all the cut portions and pieces are fed to an output conveyor which feeds them selectively to a hopper under the control of an automatic weighing machine.

    2. A machine as claimed in claim 1, in that it is equipped with pushers for the single-piece feeding of blocks
    or pieces of rubber on the feeding units, installed on the supply side.
    The invention relates to the manufacture of rubber products, for example tires, for preparatory operations, i.e. to produce weyen portions of raw cotton, which are then fed for further processing into a rubber mixer. Closest to the invention is a machine for cutting and weighing blocks or pieces of rubber and feeding them into a rubber mixer, comprising a feed member for feeding blocks of rubber to a cutting device, pressure devices for pressing blocks or pieces of rubber to a distributor, a cutting device and exhaust conveyor However, in the known device, the cutting of blocks is not carried out accurately and, as a result, the final adjustment of the weight of the portions is required to be done manually. In addition, blocks or pieces of rubber are cut by a guillotine, so the cut pieces are made in different sizes, since knives of this type are more likely to produce not a piece, but splitting off. The aim of the invention is to increase the speed and accuracy of cutting. The purpose of the invention is to ensure that in a machine for cutting and weighing blocks or pieces of rubber and feeding them into a rubber mixer containing a supplying member for feeding blocks of rubber to a cutting device, clamping blocks or pieces of rubber to the feeding unit, the cutting device and the discharge conveyor, the feeding body are made in the form of two feeding units, the first of which contains a pair of parallel belt conveyors, the second carriage installed with the possibility of reciprocating movement parallel to the belt conveyors of the first node of the node, and the conveyor mounted on the carriage with the possibility of lateral movement relative to the latter, and the cutting device is made in the form of Two cutting nodes with endless band saws, the teeth of which lie in the plane of the tapes themselves , than the tape. saws of the first cutting unit size: 1en between the belt conveyors of the first feeding unit, and the carriage of the second sub-axle unit installed between the cutting units, The exhaust conveyor is made in the form of two parallel conveyors, one of which is connected to the transport vehicles of the first delivery unit, and the other output conveyor is in contact with the second delivery node, and the machine is equipped with means for retracting the movement of the output conveyor depending on the output signals of automatic weighing, er magoguint. In addition, the machine is equipped with pushers for single-piece feeding of blocks or pieces of rubber to the feeding units, installed on the supply side. 1 shows the proposed machine, front view} in figure 2 is the same, top view; FIG. 3 is a view A (in FIG. 2). | A machine for cutting and weighing blocks or lumps of rubber and transferring them to a rubber mixer contains a feed unit for feeding rubber blocks in the form of two feed units 1 and 2. Supplements node .1 contains a pair of parallel conveyors 3 and 4, a feed node 2 - a carriage 5 installed with the possibility of reciprocating movement parallel to the belt conveyors 3 and 4 of the first feeding unit. On the carriage 5, a conveyor 6 is installed with the possibility of lateral movement relative to the latter. The machine contains a cutting device, made in the form of two cutting units 7 and 8 with endless cutting band-toothed saws 9 and 10, the teeth of which lie in the plane of the tapes themselves. The saw blade 9 is positioned between the conveyor belts 3 and 4. The carriage 5 is installed between the cutting units 7 and 8. Above the feeding units i it 2 there are clamping devices 11 and 12 for clamping the rubber blocks. The machine also contains an exhaust conveyor in the form of two parallel conveyors 13 and 14. Conveyor 13 s is engaged with belt conveyors 3 and 4 nepLoro under the entire node, and the other output conveyor 14 through the additional conveyor 15 is in contact. em with the second feed node.
    A conveyor 14 is provided from a set of inclined plates 16 which are hinged on an endless chain 17. A roller 18 is mounted on one end of each inclined plate 16 mounted on an endless train 19 located inside the endless chain 17.
    In addition, the machine is equipped with pushers 20 for single-piece feeding of blocks 21 and 22 to the delivery units 1 and 2. Moreover, the machine is equipped with means for controlling the movement of the output conveyor 14, for example, in the form of a computer controlled by an automatic weighing machine electrically connected ) with conveyor.
    The conveyor 14 is provided with a stopper 23, with which the inclined plates are stopped in the accumulation zone 24. In the course of the conveyors 13 and 14, a bunker 25 is installed.
    The device works in the following way.
    The rubber blocks 21 and 22 are pushed by the pushers 20 onto the feeding units 1 and 2. On the first feeding unit, the belt 21 is cut by means of conveyor belts 3 and 4 and is cut in half by means of a gear saw 9. These halves are transmitted to the conveyor 13. The second rubber block 22 enters the carriage 5 and the conveyor 6 is installed. The pressing device 12 moves synchronously with the conveyor 6 by a step corresponding to the thickness of the rubber piece being cut. When this occurs, the rubber block 22 is cut into pieces, with the carriage 5 moving parallel to the conveyors 3 and 4, and the conveyor 6 across the movement thereof, respectively.
    As a result of the reciprocating movement of the carriage 5 and the step-by-step conveyor b, from block 22, pieces are cut off, which are conveyed by conveyor 15 to conveyor 14 one by one. Each of the pieces is placed on a respective inclined plate 16 and guided along it to an accumulation zone 24, where they are stopped by a stopper 23. The endless chain 17 continues to move, taking the pieces from the conveyor 15.
    Further along the movement of the conveyors 13 and 14 a bunker is installed.
    25, into which, by a command of an automatic weighing device (not shown), the required number of pieces are cut off from block 22 and assembled in accumulation zone 24 of conveyor 14.
    The weighing device may be a known electric or electronic weighing device, which sends a signal that the required weight is almost reached, while. also indicated underweight weight. Those. The total measurement of the weight of raw rubber is made by loading into an automatic v3 device from a conveyor 13 a certain number of halves of the blocks 21, and then WBS is exactly normalized by adding a certain amount of pieces cut off from the blocks 22 using the conveyor 14..
    The block 22, from which the pieces are cut, does not completely break due to the difficulty of retaining and directing the remaining part when it becomes too small. The pieces are cut from about the first half of the block 22, after which the remaining part is automatically ejected from the carriage 5 onto the conveyor 13. Thus, the device cuts raw rubber blocks into pieces of two substantially different sizes. The first size pieces have a weight of about 15 K and are obtained by cutting blocks 21 into two, parts, and pieces of the second size have a weight of about 0.5 kg and are obtained by cutting from the block 22 a series of pieces, which usually have a thickness of about 10 mm.
    Therefore, metering is based on the use of a number of identical pieces in order to achieve a zyoshannogo weight with a deficiency of about 0.5 kg. This ensures accuracy within 1% if a sufficiently large zsschanny weight is used.
    In addition, cutting with such a band saw makes it possible, if necessary, to cut pieces with a thickness of up to about 5 mm, which are easy to manipulate, since they have a flat surface that is large enough so that the conveyor 15 can grab them, and they can served by suction intake devices or similar devices, with which one chunk is captured for each cut.
