Description

 The invention relates to devices for manipulating thin flexible sheets and can be used for stacking cash tickets, bonds, lottery tickets and other securities, rejecting sticky, wrinkled, torn sheets, as well as sheets whose thickness is beyond the established parameters, and issuing stacked sheets to the user.

 A device for processing sheets (Europatent 0499458, MKI G 07 F 19/00, publ. 12.07.1995) containing a conveyor for feeding sheets, a detection unit for defective sheets, means for stacking sheets in a stack, a conveyor containing endless flat belts for issuing a foot to the user.

 However, this device has a significant drawback in operation - after passing the defective sheet through the defective sheet detection unit, the defective sheet is detected, after which the sheet is placed in the common stack of sheets to be dialed, the set of sheets is stopped and the already collected stack of sheets, with the rejected sheet, is transported to the cassette storing defective sheets, after which the set of sheets begins anew. As a result, the time for collecting a stack of sheets for delivery to the customer increases, the number of sheets transported to the cassette storing defective sheets increases, which in turn reduces the overall device operating time between collections.

 The closest in technical essence and adopted by us for the prototype is a device for issuing sheets (Europatent 0155174, MKI B 65 N 29/40, publ. 12.03.85), containing the first transporting device for transporting sheets to the place of stacking in the foot; defective sheet detection unit; a deflecting device comprising a movable guide cooperating with the first conveying device and guiding the sheets along the first conveying device and moving in accordance with the output signal of the defective sheet detection unit to reject defective sheets to the first transporting reject device supplying the defective sheet to the defective sheet storage cassette; a device for laying sheets in the foot after the first conveying device; a device for clamping the foot to the second conveying device; a second conveying device delivering the stack from the stacking position to the dispensing window.

 In front of the dispensing window, there is a second deflecting device for guiding the stack along the second transporting device to the dispensing window or along the second transporting device for rejecting the defective sheet storage cassette, if the wrong number of sheets was typed or the user decided not to accept the stack of sheets.

 The disadvantage of this device is the design complexity: a large range of belts and pulleys that are part of the first transporting device, the second transporting device, the first transporting rejection device, the second transporting rejection device; the presence of two deflecting devices, guiding the sheets or a stack of sheets on different ways of transportation. All this together reduces the reliability of the device, complicates the control system, increases the complexity and cost of manufacturing.

 The technical result of the invention is to increase reliability, simplify design and management, reduce the complexity and cost of manufacturing the device.

 The technical result is achieved in that in the device for issuing sheets containing a detection unit for defective sheets, a conveyor consisting of rubberized shafts with parallel axes for transporting the sheets to the place of stacking them in the stack, a deflecting device with a movable guide for guiding the defective sheet along the rejection conveyor to cassette for storing defective sheets in accordance with the output signal of the unit for detecting defective sheets, a device for stacking sheets in the stack, consisting of a number of stacking wheels on a common shaft and a holder for receiving sheets and forming a stack, a device for clamping a stack of sheets to a conveying device consisting of a series of endless belts driven by two pulleys with parallel axes and enveloping a series of rollers with parallel axes for transporting a stack of sheets to the dispensing window or transporting it in the cassette for storing defective sheets in case the client does not accept the foot, the rejection conveyor is made in the form of three rubberized shafts with parallel axes and special guides, made в in the form of figured plates, and the holder for receiving sheets and forming the stack is made in the form of a series of plates connected on one common shaft with the possibility of rotation around its axis and the direction of the stack of sheets in the storage cassette of defective sheets, a cam mounted for rotation is also introduced around its axis and having two leading channels for setting the trajectory of the holder for receiving sheets and forming a stack and a device for clamping a stack of sheets to a conveying device.

 The essence of the invention lies in the fact that the rejection conveyor is made in the form of three rubberized shafts with parallel axes and special guides made in the form of curly plates, the holder for receiving sheets and forming the stack is made in the form of a series of plates connected with the possibility of rotation around its axis and the direction of the stack of sheets in the cassette storing defective sheets, also introduced a cam installed with the possibility of rotation around its axis and having two leading channels for defining the path of two zheniya holder for receiving and forming the sheet stack and pressing the stack of sheets to the conveying device apparatus, allowing to simplify the structure, reduce the complexity and manufacturing cost, simplify the device management, increased reliability of the device.

 The device (Fig. 1-3) comprises a defective sheet detection unit 1 located between the two panels 21 and 22, a conveyor consisting of rubberized shafts 2 with parallel axes for transporting the sheets to the stacking place, a deflecting device 4 with a movable guide for guiding defective sheet on the rejection conveyor, which is driven by an electromagnet 5. The rejection conveyor consists of rubberized shafts 3 with parallel axes. Between the rubberized shafts 2 and the rubberized shafts 3 there are special guides 6 for guiding the sheet between the rubberized shafts 2 and 3 to the place of laying sheets in the stack 19 or in the cassette 16 storing defective sheets. The device also contains a number of laying wheels 7 on a common shaft and a holder 8 for receiving sheets and forming a stack of 19 sheets, a device 9 for clamping a stack of 19 sheets to the endless belts 10 of the conveying device. The conveying device located between the holder 8 for receiving and forming the foot 19 and the dispensing window 20 consists of pulleys 11 with parallel axes, rollers 12 with parallel axes and endless belts 10 that run around these pulleys 11 and rollers 12.

 On the panel 21 (Fig. 2) there is a common drive motor 13 and a drive motor 14 of the device 9 for clamping the feet 19 to the endless belts 10 of the conveying device and the holder 8 for receiving and forming the foot 19. On the panel 21 there is also a cam 17 (Fig. 2 and figure 3), by means of which the device 9 clamps the tables 19 to the endless belts 10 of the conveying device and the holder 8 for receiving and forming the foot 19 is driven. On the panel 22 (figure 2) there is a motor 15 of the drive of the conveying device consisting of pulleys 11, rollers 12 and endless belts 10.

 The device also contains control units 18 (Fig. 1) for controlling the movement of individual sheets and a stack of 19 sheets along the track and finding them in certain positions and a cassette 16 for storing defective sheets, consisting of two compartments "A" and "B" (Fig. 1 ) Branch "A" is intended for receiving sheets rejected by the defective sheet detection unit 1, department "B" for receiving a stack of 19 sheets in the event that the wrong number of sheets is collected or the user decided not to accept the stack of sheets.

 In the device case (not shown in the drawing) there is a dispensing window 20 for issuing a stack of 19 sheets to a client.

 The device operates as follows. Sheets coming from the sheet storage cassette (not shown in the drawing) are transported using rubberized shafts 2 between special guides 6 to the place of laying sheets in the stack. During transportation, the sheet passes through the block 1 detection of defective sheets, which captures a double or wrinkled sheet, as well as a sheet whose thickness is beyond the specified parameters. If the sheet meets the specified parameters, then it is transported to the laying wheel 7, which lays the sheet on the holder 8 for receiving sheets and forming a stack.

 In the case of passing through the block 1 detection of defective sheets of a sheet whose parameters do not meet the established standards, in accordance with the output signal of the block 1 for detecting defective sheets, the electromagnet 5 activates a deflecting device 4 with a movable guide, which in turn guides the defective sheet with rubberized shafts 3 along special guides 6 to compartment "A" of the cassette 16 for storing defective sheets.

 After collecting the number of sheets ordered by the customer and forming a stack of 19 sheets on the holder 8, the clamping device 9, which presses the formed stack of 19 sheets to the belts 10 of the conveying device, is actuated by the motor 14 and cam 17. At the same time, the holder 8, also by means of the engine 14 and cam 17, rotates around the axis and forms a path of movement of the stack of sheets in the compartment "B" of the cassette 16 storing defective sheets.

 The pulleys 11 through the engine 15 drive the belts 10, which, running around the rollers 12, transport a stack of 19 sheets to the window 20 issuance.

 If the client for some reason does not take a stack of sheets, after a certain period of time, it is transported by the belts 10 of the transporting device to the compartment "B" of the cassette 16 for storing defective sheets, after which the holder 8 and the clamping device 9, by means of an engine 14 and cam 17 are returned to their original position, that is, the position for receiving bills from the laying wheel 7 (FIG. 1).

 The advancement of individual sheets and the stack of 19 sheets along the track and their location in certain positions is controlled by control units 18, which are an optical pair (phototransistor and LED).
