Description

the sides of the letters, the belt-roller mechanism of movement, the distributor of a series of paired belt conveyors and valves, the means of rotation by 90 ° along the long axis, made in the form of a curved tray installed transversely to the axis of the conveyor and tilting the letter onto the belt.

The disadvantage of the machine is that the links to each cross conveyor are supplied only in two positions of the brand, index, so the letters need two cross conveyor belts, each with a paired valve and a curved tray, all the mechanisms located on the same plane, which requires a large production area and the additional cost of materials and energy.

The advantage of a sorting, facializing and stamping machine is that it has a two light design. On the first floor, there are devices for recognizing the front side and entering letters into the distributor. On the second floor, transverse conveyors with gable guides mounted above them rotate flat objects 90 ° along the long axis.

The disadvantages of this machine include the difficulty of coordinating the operation of the input device and distributor, cassettes and windows for resetting letters to the gable rails, as well as transporting letters in the distributor in a transverse position on the edge, which leads to an increase in the size of the machine.

The purpose of the invention is to simplify the design of the machine.

This goal is achieved by the fact that in a machine for facing and stamping letters, including a receiving drive, a separator, face recognition devices, a conveyor of the first tier with a U-shaped trajectory of the letters, a gabled track with a second tread conveyor located below it, a couple of means The 90 ° counter-turn around the axis is located directly behind the symbolic device and is equipped with a dead-end trap, in front of which a pair of rollers and a two-position arrow are installed, and The shock absorber is fixed to the peak wall of the trap and there is a slot at the bottom, and a double-sided arrow is installed on the ridge of the gable rail, each side of the conveyor forms an acute angle with the belt plane and has a longitudinal zig forming a canopy above the belt, and in the upper part of the bead they expand, in addition the conveyor of the first tier is roller, and the pressure guide of the driving drum has a U-shape, straight lines

which are rigid and curved - elastic, after the stamping mechanism an interface device is installed, consisting of two conveyors of different lengths and with the possibility of transition from a horizontal position to a vertical one, while the transition sections are provided with pressure guides, it is also possible to use a gable a guide in the form of a two-console plate with a turning axis located parallel to the axis of the conveyor above the plane of the belt.

FIG. Figure 1 shows a machine for facing and stamping flat rectangular objects, a block diagram; in fig. 2 0 the same general view; in fig. 3 and 4 are two versions of a gable guide with a two-position arrow.

The machine contains receiving tank 1, separator 2, identification device.

5 3, two-way arrow 4, tool 5 rotates 180 ° around a short axis, drive for unidentified letters 6, paired tool 7 of counter-rotation 90 ° around the long axis, stamping mechanism 8, tool 9 merging two streams.

FIG. 2, a dead-end trap 7a with a slot and a shock absorber 76 is shown. The means for merging two streams, which is simultaneously mating with the next machine in the line of processed letters, includes two belt conveyors 9a with pressure guides 96.

FIG. 3 shows a two-position

0 arrow 7c on the ridge on the fixed gable rail 7g, the belt conveyor is equipped with flanges 11, having a longitudinal zig in the lower part, forming a canopy above the conveyor belt, and

The 5 parts of the bead are expanded.

FIG. Figure 4 shows an alternative variant of a gable rail, made in the form of a double cantilever swivel plate 12 with an electromagnet 12a and a spring 126.

Receiving drive 1 serves to accommodate a stack of letters to be faceted and stamped. Involves the use of well-known in postal communication

5 drives with the mechanisms for filing a foot of letters. Separator 2 separates the letters one by one from the foot and directs them to the input rollers of the identification device. Separators are widely used in postal services. The most acceptable friction

or friction vacuum separators. The identifying device is used to detect one of the four positions of the possible positions of the front side by the service mark applied along the short edge of the envelope, the photoelectric postcard and consists of two read heads, sensors of standard size, AND, OR circuits, logical unequalities and logical multiplication nodes.

The tool 5 for turning letters through 180 ° around a short axis consists of a driving drum with a U-shaped pressure guide. Its inlet and outlet portions are rigid, and the bend portion is elastic.

The deadlock trap 7 is designed to change the direction of movement of letters from horizontal to vertical, from top to bottom. A two-position arrow 4 is installed at the entrance of the trap, driven by an electromagnet in one direction and returned from the spring. A shock absorber 7a is installed on the dead-end wall of the trap, for example, in the form of a paralon plate. At the bottom of the trap there is a longitudinal slot 7a, the length of which is equal to the envelope diagonal. The two-way arrow 7c sends letters, depending on the position of the tag, through one of the ramps 7g to the conveyor belt 10. The ramps and the borg 11 turn the letters 90 ° along the long axis.

Conveyor 10 fits letters in one position of the stamp to the stamp mechanism 8 for applying a calendar stamp. A longitudinal rectangular ridge at the bottom of the bead serves to form a canopy over the conveyor belt, which prevents the letters from jamming between the conveyor floor and the ramp.

The device 9, when either two streams are used, simultaneously serves as an interface with another machine in a line and consists of two conveyors 9a of different lengths. The plane of the tape of each of them moves from a horizontal position to a vertical one. The clamping guide 96 provides frictional movement of letters. There are two options for placing the device 9 if it is the first, as in FIG. 2, the second - in the opposite direction. The second option requires less production space, since most of the interface device is located under the table of the first tier.

The rotation of the arrows 4 and 7 and the dual console plate 12 in one direction is performed by the electromagnet 12a, in the other direction by the spring 126.

The machine works as follows.

Letters, envelopes in four random positions of the foot mark are fed to the drive. The separator separates the letters one by one and brings them to the identification device on the long edge. Information from the latter through the appropriate time delay circuits is fed to the electromagnets of the trap arrows and the gable guides. Letters in two positions of the mark, for example, in front, are fed to the first trap. Letters with a label on one side are served only on one ramp, letters with a label on the other side - on the 5th opposite ramp. Each letter with marks on opposite sides of the ramps and sides is rotated when pulled by a ribbon through 90 ° and is in one position with its front side on the conveyor belt. The letters are then forwarded to the stamp mechanism.

The machine can operate in two modes: autonomous or as part of a line.

In the first case, the machine contains a receiving drive and a separator at the inlet, as well as a drive at the outlet in the form of boxes or cassettes.

In the second case, the machine is supplied with interface devices both at the input and the output 0.

The use of a simple gable guide with sides inclined at an acute angle to the belt plane makes it possible to rotate letters by 90 ° along the longitudinal axis without energy.

Simplification of the design is achieved by a new device that identifies the front side of the envelope by the service mark applied along the short edge of the envelope, and also by the fact that in the proposed letter machine, manipulations with letters begin immediately after recognition, which allows you to refuse 5 seconds from the letter input device distributor.

The rotation of letters by 180 ° around the long and short axes is solved constructively simply and compactly, which

0 allows you to create a desktop version of the machine.

Equipping small and medium-sized enterprises with such machines increases labor productivity and improves its conditions.

5, how the letter handling operations are performed manually there. The cost and time of manufacture of the machine is reduced, since its structure is simpler and more technological, it takes up less space, its operating costs are lower, so the use of the machine will bring savings in the national economy.
