Description

Machines are already known for the manufacture of grating boards with obliquely arranged shingles by mechanical means, in which the supply of grooves from shops is carried out by endless conveyors with grabs. In the proposed machine, with the aim of mechanizing the process of making grating boards, two pairs of hook-shaped grippers are used to grip shingles on the conveyor belt, which can be lowered to grip the bottom row of the first store panties and rise up to remove the second store boxes that are lighter than the bottom row. Dranok the first store.

In FIG. 1 shows a schematic side view of the machine; Fig.2- then in the top view; FIG. 3-section of the machine; FIG. 4 and 5 sections of the store; FIG. 6 shows a section of the table of the machine showing the position of the grippers; FIG. 7, also in a plan view, FIG. 8 is a section of the store and part of the table of the machine; FIG. 9 is a side view of a modified machine; FIG. 10 is the same in top view; FIG. 11 view from above

a mechanism for pushing the basket; FIG. 12 is the same in the side view; FIG. 13 is the same in section; FIG. 14 is a top view of the slots in the mite of the second conveyor; FIG. 15 is a side view of the removable protrusion of the mechanism for pushing the troughs; FIG. 16 is the same in section; fng 17 is a side view of the spring grip for the slats; FIG. 18 - the same in the top view; FIG. 19 is a section of the store with the indication of a device capturing shingles from it.

The bed of the proposed machine consists of tubes 5, 6, (Fig. 1-3). The tubes are equipped with two magazines 7 and 7 located either perpendicularly or at an angle to each other. Shops are equipped with sockets 8 at the top and notches 25, delineated in such a way that shingles 9 can be more conveniently stacked in shops with bundles (from 20 to 200 shtyuk). A light table 20 is attached to the tubes 5, on which the lower row 15 of dry cups 9 of the store 7 and a row of 6 draynok 9 of the store 7 are located, with the row of 9

store 7 is located above a number of 15 draanok 9 store 7.

The tubes 5 are also reinforced with pulleys 3 carrying an endless flexible band (or chain) / provided with straps 2, the pulleys 5 being driven in rotation by the handle 4.

When the handle 4 is rotated, the tape 1 receives movement, and the shingles coming from stores 7 and 7 in the manner indicated below are arranged in the form of a grid shield 10, which is then cobbled by hand with nails.

Laying pails from stores 7 and 7 is done this way. Store 7 (Fig. 4-8) has a longitudinal slot 22 at its bottom, which can pass out the bottom shingles captured by some mechanism. The grip mechanism for tins consists of two hook-shaped grippers 13 and 13 attached to the strips 2 tapes /. The grippers 13 and 75 when moving the tape over the notch 30 in the table 20 fall down and do not extend their upper ends beyond the upper edges of the strips 2 of the tape. This is achieved in that the protrusions 28 on the grippers 13 and 13 are held in the recesses 24 of the strips 2 and are made so that the grips 13 and 13 can go below the located 15 rows of saucers 9 of the store 7 and remove the next shingle 16 from the store 7 .

When approaching the magazine 7, the gripper 13, having passed the notch 30 of the table 20, is raised by the inclined plane 2 and the spring 27 to the position shown in FIG. 8, and upon further movement of the belt 1, pushes the next shingles 16 out of the magazine 7 onto the belt 2, with the shingles directed from above by a visor 14 (Fig. 8).

For a smooth grip of the drank during the rapid course of the tape 1, a spring 29 serves (fig. 4, 7).

As the nails are hammering, the endless shield 10 comes off the machine and is cut into pieces of the desired length.

The machine described above can be modified, and instead of one conveyor with an endless mite /, a second conveyor is also used with a drilling direction perpendicular to the first one. In this case, as in the previous one, the machine bed consists of tubes 5, in (figs. 9, 10) on whose pulleys 5 an infinite belt is placed / driven by rotation of the handle 4. Handle 4 is provided with a pinch // when entering the upper part of their path into the forks 12 of the pulley 5.

When passing through the lower part of the trajectory, the spike // enters the forks 17 fixed on the axis of the gear wheel 18 connected to the gear wheel 19 mounted on the end of the rod 21 carrying the gear wheel 23 at the other end. The wheel 23 interlocks with the gear wheel 31, mounted on the drum axle 32, on which the endless belt of the second conveyor 55 is placed, provided with slots 34. The belt 55 also covers another drum 35, which is used for laying in the manner described below, drapes 9 from the magazine 36 onto the belt 55.

The shingles 9, laid on the tape 55 to the position 57 (Fig. 11), are then dropped by the claws 58 into the slots 34 and fall onto the 5P shingles 7 laid (from the store 7), forming the upper shingles of the endless shield 10. Transferring movement from the handle 4 made so that when the tape is moving / the tape 55 is at rest and vice versa.

Store 36 (Fig. 19) has a longitudinal slit 40 ALY of shing 9 output and transverse slits 42 in the bottom and lower side of the side wall for the passage of pushes 9 pushing the gibber 9. The tabs 41 are located on the drum 55 supporting the second conveyor belt 55 and pushing the shing 9 from magazine 5; it is fed under a visor 14, which directs shingles to the conveyor belt 55. The feeding of the curtains 39 from the magazine 7 is made either by the method described above in the description of the first machine, or it can be done in the same way as the feed from the store 36.

After filing shingles 9 in this way at position 57, it should be submitted to shingles 39 (Fig. 12),

which are fed to the tape in advance. This supply of trowels to position 47 through the slots 84 of the conveyor belt 55 can occur in two ways, namely: 1) all shingles 55 are simultaneously dropped by the clamps 55, or 2) shingles are reset one after the other by the grips 58 after each advance of the tape doo shields 10.

The process of feeding the panties to the position 47 on the strips 89 is carried out in this way (Figs. 10-15, 17, 18): the conveyor belt 55, while moving, rests on the beams 48 installed to eliminate the ribbon sag, with axes 44 fixed on the beams 48, on which the pruning claws 58 rotate, pressed by the springs 45 to the tape having a system of notches 84, located on the left side (Fig. 14) in one order, and on the right side in reverse order to the first.

The grippers 58 are provided with protrusions 46, which are pressed all the time to the conveyor belt 55 by means of the spring 45. All the grippers 58 are the same, but are arranged somewhat displaced one with respect to the other (Fig. 14).

When the conveyor belt 55 moves, the protrusions 46 of the grippers 58 will simultaneously fall into the slots, with the grippers 58 falling on the shingles located at position 57 and dropping them down to position 47 through the slot 84 with their brackets 48 (Fig. 11-13). The moments of dropping the drapes 57 to the position 47 are coordinated with the moment the tape stops.

When the conveyor belt 55 moves, the shingles 57 are held in a position defined on it by means of springs 62 (Fig. 11), which cover the shingles in the lateral position 57c, simultaneously with its exit from the magazine 86. Rod 49 serves to eliminate the possibility of the spring 62 engaging the magazine 86 The spring 58 can be replaced by a combination of two springs 50 and 51 (FIG. I), the first of which limits the lateral movement of the shingles in position 57i and the second presses the shingles from above. The spring 51 is made in such a form that it rises when passing past the side wall of the magazine 86 and presses the bar at position 57, falls on it as soon as it passes the wall of the shop.

Once laid, the tape 55 on the tape / shingles in position 47 (Fig. 12) is compressed laterally by means of a spring 52, which has the purpose to hold the shingles in a certain position 47 when the tape is moving / until removed from the last after being stitched together.

The springs 52 have the form shown in FIG. 12, 17, 18. Spring 52 can be sunk downward, rotating on its axis 58, and held in a recessed position by abutment on the belt / hems 68 as the spring 52 moves over the notch in the table 20. The spring transition from the lower position to the position shown in fig. 12 is made using protrusions 59 installed in a recess of the table 20 and provided with upwardly extending longitudinal grooves 60 at the level of inclined platforms 56. As the springs 52 exit, the springs 52 move apart and become in the position shown in FIG. 12. The tape / stops before the spring 52 leaves the grooves 60, and after the tape stops / the tape 55 comes in motion and the shingles are reset from position 57 to position 47 between the pins of the spring 52 moved apart. Then tape 55 stops and tape 1 begins to move, causes the release of the springs 52 from the grooves 60 and the compression of the shingles by the spring 52,

Springs 52 are two to stack each longitudinal bar. The protrusions 59 are also made two for each longitudinal row, and the notches in the table 10 are under the tape in an amount equal to the number of longitudinal rows of drains.

Thus, after the filing of tins from position 87 on shingles 89, a rectangular grid of troughs is obtained in the form of either individual shields 10 or an endless ribbon, which is knocked off on the table 53

(Fig. 10) and then removed from the table or cut with manual or mechanical scissors into pieces of the desired length. The projections 46 on the arms 38 can be made removable (Figs. 15-16).

The subject matter of the invention.
