The invention relates to processing equipment for rod-like objects, for example, electrical contacts, connect & A device for stacking rod-shaped objects is known, comprising a feeder made in the form of a hopper and a multi-slot vibratrack fixed on flat springs, a cassette whose upper walls of the openings have grooves of a length greater than the objects passing over the diameter of the objects in the lower part of the cassette , a horizontal movable comb on which the pins are fixed, and their length corresponds to the deepest axial bore of the objects, moreover, the pins are fixed parallel to the tooth At the distance from the last one, equal to half of the largest diameter of objects, the mechanism of single discharge with the left and right ends, gear reflector of the drive of the feeder 1. The disadvantage of the device is low productivity due to the fact that at the moment of orientation of rod-like objects it is necessary to turn off the vibration of the rod. In addition, the reliability of the device when laying rod-like objects prone to adhesion is reduced, since the objects accumulating in the grooves of the multi-slot vibrating channel are interlocked with each other and are not separated when the piece dispensing mechanism is triggered. The closest to the invention according to the problem to be solved and the effect achieved is a bunker for. accumulation and distribution of rod-shaped products. containing one bottom of another, mounted with the possibility of moving the cutter and bar, each of them has a number of windows and slots with slots. Moreover, the bunker is installed with the possibility of rotation about the horizontal axis, and the bottom of the window has a gate-cutter, a cassette. in the upper part of which there are grooves of a length greater than the length of the objects, passing in the lower part of the cassette into the holes with a diameter greater than the diameter of the objects, a comb moving in the horizontal plane, the width of the slot with the grooves smaller than the diameter of the collar of the objects and the bottom of the grooves combs for a distance equal to the sum of half the diameter of the collar and half the larger diameter of one of the ends of the object. The sleaze consists of two parts, one of which is rigidly attached to the bottom of the bunker, and the other - to the base of the device. The windows in the bottom of the bunker are located coaxially with the slits of the slits. the slots of the anvil and the teeth of the comb 2. The disadvantage of the device is its low productivity due to the presence of idle strokes of the shutter and the duration of the hopper rolling to sink rod-like objects into its window. In addition, the reliability of the device is reduced due to the fact that after stopping the bunker in its initial (right extreme lower) position, not all rod-shaped objects roll into the right side of the bunker bottom, and some of them are held up by objects sunk into the bottom windows, which makes it possible issuing in the same groove multi-slice more than one object. The purpose of the invention is to increase the productivity of the bunker by eliminating idle strokes of the shutter. The goal is achieved by the fact that in the bunker for the accumulation and delivery of rod-like products, containing bottom plates located one above the other, mounted with the possibility of movement, a cutter and a bar, each of which has a row of windows, and a slice with eyes, a bottom, a cutter and a bar additional rows of windows, the number of which is chosen so that the total number of rows for each of them is even, but not less than four, the rows are placed with the formation of sections, including two rows, with the bottom of the window of each section being offset relative to the windows of the adjacent sections for a distance equal to twice the distance between the slits of the slits, the window shutter of each section is offset relative to each other by a distance equal to the distance between the slits of the slits, the windows of the “Lanka” section are coaxially, while the windows of one cutter section are aligned with the windows of the corresponding the bottom section, and the windows of the other section - with the windows of the other section of the rail. FIG. 1 shows a device for laying rod-shaped objects, side view; in fig. 2 is a view A of FIG. one; in fig. 3 is a view B in FIG. one; in fig. 4 - cut-off with windows; in fig. 5 - slat with windows; in fig. 6 - sections BB, GG, dd E-E in FIG. 2 (shut-off valve in the extreme right position); in fig. 7- sections IB of D-D and E-E in FIG. 2 (shut-off valve in the leftmost position); in fig. 8 - an emphasis with grooves; and fig 9 is an orientation scheme of objects that have entered the stop grooves with longer ends (sections); in fig. 10 is an orientation scheme for objects that have entered the grooves with shorter ends (sections). The hopper for accumulating and dispensing rod-like objects (Fig. 1) contains a base 1, on which an electromagnet 2 is fixed, a cassette 3, flat springs 4, to the upper ends of which a multi-slot vibratory channel 5 with grooves 6 is attached, and supports 7 on which axes 8 (Fig. 2) the tray 9 (fig. 1) is rotatable relative to the horizontal axis. In the bottom of the rotary chute 9, windows 10 and 11 are provided, under which cutter 12 (fig. 1, 4) with windows 13 and 14 and fixed plate 15 (fig. 1, 5) with windows 16 are mounted with the possibility of movement perpendicular to their longitudinal axis. and 17. The length of the windows 10, 11, 13, 14, 16 and 17 (Fig. 1, 2, 4, 5) is longer and the width of the collar of the collar is larger than the diameter of the rod-shaped objects 18, with windows 10 and 11 in the bottom of the tray 9, Windows 13 and 14 in the cutter 12 and Windows 17 and 16 in the bar 15 are made in two rows, the total number of rows for each of them is even, but not less than four rows are placed with the formation of sections, including two plots yes. The thickness of the trimmer 12 is equal to the larger diameter of the collar of the rod-shaped object 18. Between the rotary chute 9 (Fig. 1) and the multi-groove vibrating channel 5 there is a multi-slider slot with 19 grooves consisting of two parts, the left part 20 of the slice is rigidly fixed to the bottom of the rotary chute 9 and the right part 21 is fixed motionless on the supports 7 (the supports 7 are fixed to the base 1). The bottoms of windows 13 and 14 of each section are offset relative to the windows of the adjacent section by a distance equal to twice the distance between the slots 19 of the slide. In the right-hand side of the multi-slot vibrating channel 5 (fig.), Above the cassette 3, a comb 22 in the horizontal plane is mounted with teeth 23, above which a stop 24 with grooves 25 is fixed. The grooves 25 width (fig. 8) in the stop 24 are smaller than the diameter of the collar 18 (FIG. 1), and the bottom of the grooves 25 is spaced from the upper plane of the teeth 23 movable in the horizontal plane of the comb 22 at a distance equal to the sum of half the diameter of the collar and half the larger diameter of one of the sections (ends) of the objects 18. Windows 16 and 17 of the bar 15, grooves 19 left 20 and right 21 parts of the multi Zoom, the grooves 6 of the multi-section vibrating channel 5, the grooves 25 of the fixed stop 24 and the tooth 23 in the horizontal plane of the comb 22 are aligned coaxially with each other. In the initial position, the cutter 12 (Fig. 6, B-B and G-D) of the window 13 and the window 10 of the bottom of the tray 9, the window 14 (Fig. 6, D-D and EE) and the window 17 of the bar 15 are respectively aligned between the windows 11 of the bottom of the bunker 9 are offset relative to the windows 14 of the cutters 12 by an amount equal to the pitch of the grooves 19 of the multi-slot tray, and the windows 16 (Fig. 6, B-B and G-D) in the bar 15 are offset relative to the windows 13 same side and same size. The total number of windows 10 and 11 (Fig. 2, 4, 5, 6, 7) in the bottom of the tray 9, windows 13 and 14 in the cutter 12, windows 16 and 17 in 15 are equal to each other and equal to twice the number of notches 19 multi-slot sliza. To move the comb 22 in a horizontal plane (Fig. I) to the extreme right position serves electromagnet 26, which is fixed by means of a bracket 27 on cassette 3, and to move the selector 12 (Figs. 1 and 2) to the extreme right positions, use right} (not shown). Limiters 28 (Fig. 3) are designed to control the stroke of the comb 22 which is movable in a horizontal plane. A drive (not shown) serves to inform the rotary chute 9 (Fig. 1) of the swinging motion in the vertical plane. The electromagnet 2 (Fig. 1) and the flat springs 4 are designed to vibrate the multi-slot vibrating channel 5, and the spring 29 is intended to return the comb 22 in the horizontal plane to its original position. The device works as follows. When turning on the drive of the rotary tray 9 (Fig. 1 and 2), the latter is rotated in a vertical plane on the axes 8, and rod-shaped objects 18 poured in bulk in the rotary tray 9 fall into the windows 10 and 11 of the tray 9. Objects 18 sunk in Windows 11 (Fig. 6 D-D and E-E) of tray 9, are kept from falling down by a plane a cutter 12, and only one item 18 falls into each window 11 of this row, and items that fall into window 10 ( 6, B-B and D-Y) of the tray 9 of the other row, moving under the action of its own weight, enter windows 13 from The shoal 12 and is kept from falling down by the plane into the strips 15, while freeing the windows 10 of the tray 9, into which as the tray 9 is further rotated, the objects 18 again fall. Thus, by simultaneously sinking the objects 18 into the windows 10 and 11 of both rows of the tray 9 A preliminary accumulation of objects 18 in windows 11 is carried out in an oriented position relative to their longitudinal axis for feeding objects 18 to the orientation and laying position. After all the windows 13 of the shutter 12, which are combined with the windows 10 of the tray 9, are filled with rod-shaped objects 18, the drive of the rotary tray 9 (Fig. 1) is turned off and the latter stops in the initial position (right-most bottom). At the same time, most of the items roll into the right side of the bottom of the bunker 9, and some are held up by the collars of the objects sunk into the windows 10 and 11 of the bottom of the tray 9. Simultaneously with turning on the drive of the rotary bunker 9, the electromagnet 26 is turned on (Fig. 3) and is movable in the horizontal plane the comb 22 moves to the extreme right position until it stops at the stop 28, as a result of which orienting windows C are formed (Figs. 9 and 10). After the time required for orientation of the objects 18, the electromagnet 26 (FIG. 3) is turned off and the comb 22 in the horizontal plane is returned to its original position (leftmost) by the action of the spring 29, after which the actuator 12 (Fig. 7) turns on and the latter is moved to the extreme left position by an amount equal to the step between the slits 19 of the slide. The windows 13 (Fig. 7, B-B and D-D) of the shutter 12 are combined with the windows 16 of the bar 15 and the windows 14 (Fig. 7, D-D and EE) with the windows 11 of the bottom of the tray 9, and objects 18, sunk into the windows 13 (Fig. 7, B-B and D-Y), are separated from the main mass by a shut-off valve 12 and under the action of their own weight enter the windows 16 of the bar 15 and then into the slots 19 of the left part 20 the multi-tray slit, moving along them, goes into the slots 19 of the right part 21 (FIG. 1) of the slip and then into the slots 6 of the multi-slot vibrating channel 5. Subsequently, under the action of vibration generated by the electromagnet 2, the rod-shaped for etya 18 move along the grooves 6 of the multi-slot vibrating channel 5 and go into the grooves 25 (figs. 9 and 10) of the fixed stop 24 with longer or shorter sections (ends), resting their shoulder on the surface d of the fixed stop 24. At the same time Items 18 (Fig. 7, D-D and E-E), sunk into the windows 11 of the bottom of the tray 9, under the action of their own weight, go into the windows 14 of the shut-off device 12. The drive of the tray 9 is activated again (Fig. 1) and an electromagnet 26 of the comb 22 being movable in a horizontal plane. Tray 9 is set in oscillating motion, in which objects 18 again fall into the windows 10 and 11 of tray 9, i.e., the next defined portion of rod-shaped items 18 are being prepared and accumulated for delivery to orientation and styling. When the electromagnet 26 (Fig. 2) is turned on, the comb 22 in the horizontal plane moves to the extreme right position until it stops at the stops 28 and the orienting windows C are re-formed (Fig. 9 and 10), and the objects 18 are kept from moving after the comb 22 by the surface d a fixed stop 24. When forming the orienting windows C, a short portion (end) of objects 18 is released. 18. Objects. 18 (Fig. 9), which are clamped into the slots 25 of the fixed stop 24 with longer sections (ends), rotate around the left end of the teeth 23 and the comb 22 in the horizontal plane, pass into the slots of the cassette 3, which are moved along the stack or tare (not shown), shorter sections (ends) down, and objects 18 (Fig. 10), which entered the grooves 25 of the fixed stop 24 with shorter sections (ends), rotate around the right end of the grooves 6 of the vibratory tray 5, moving into the slots of the cassette 3, moving in which, are placed in the product or tara also shorter sections (ends) down. Thus, no matter which section — longer or shorter — the objects 18 are clamped into the slots 25 of the fixed support 24, they are placed in the product with the shorter section down. After orienting the objects 18 (Fig. 3), the electromagnet 26 is turned off, and in the horizontal plane the comb 22 is movable under the action of the spring 29 returns to the initial (leftmost position). Tray 9 (Fig. 1) has already occupied its initial (rightmost lower) position by this time, the cutter 12 is switched on again, the latter is moved to the initial (rightmost) position. The windows 14 (Fig. 6, D-D, E-E) of the cutter 12 are combined with the windows 17 of the bar 15 and the windows 13 (Fig. 6, BB, G-D) - with the windows 10 of the bottom of the tray 9, and Objects 18 that fall into windows 14 (Fig. 6, D-D and E-E) are separated from the main mass by a cutter 12, under the action of their own weight, slats 15 enter windows 17 and then into grooves 19 of the left part 20 of a multi-slot tray scaling, and the cycle repeats. Equipping the bunker with a window with windows, making windows in the bottom of the bunker, gate of the cutter and bar in two rows and arranging them in each of the rows in staggered order, installing the gate shutter with the ability to move perpendicular to the longitudinal axis of the bottom windows of the bunker allows to increase device performance by eliminating idle strokes of the shut-off valve and shortening the hopper sweep time due to the provisional accumulation of objects in the bottom windows of the bunker; increase the reliability of the device by eliminating the influence on the cut-off of objects that are not rolled into the lower part of the bottom of the bunker, and eliminating the influence of the adhesion of the product (paled)
