Description

8-101704-8 10 15 20 25 30 35 2 Consequently, during the operation of the known device, waiting times arise which the printing plant needs to require the necessary working time to record information. at high working speed. For such a device, the printing plant is only a subordinate component, which should not lead to any decisive increase in cost. the device.

The object of the invention is to provide a device of the type described in the introduction, which, despite the use of simple printing presses, is characterized by a high working speed. This object is achieved according to the invention in that a switch, which reacts for a tear-off of the receipt part from the information carrier and which serves as a trigger for the printing unit for recording the permanent pressure on the information carrier, is assigned to the tear-off edge of the device. As a result, a considerable part of the function of the printing unit will automatically take place during the periods of time which are still not used for any other function of the device. The operator, for example the seller who serves the price-calculating scale, is busy tearing down and producing the receipt to complete the purchase by handing over the receipt to the buyer and receiving the purchase price. This period of time is now used according to the invention by the device for preparing at least essential parts of the permanent print on the receipt which is to be available for a future purchase. Thereafter, the device is immediately prepared for subsequent work. Thus, waiting times are eliminated.

Depending on the nature and quantity of the relevant item hereafter intended for purchase, the associated individual data is registered on the receipt, which manual feed cells are determined according to the weight of the item or in terms of calculation. The registration work required for each individual item in the printing plant is in comparison with the small-scale permanent printing and is therefore no longer important.

In any case, the extensive registration work in the area of permanent printing has already been completed. 10 15 20 25 30 35 8101704-8 3 There are various possibilities to use the tear-off process as a trip pulse for the printing unit so that it registers the permanent pressure. A simple possibility lies in arranging the tear edge itself resiliently movable and using the tear-away movement of the tear edge towards a spring force holding a spring force in the initial position for said release of the pressure unit. Namely, it is sufficient to arrange the actuating means for said switches in the path of movement of the tearing edge or for holding means which are arranged to follow the movement of the tearing edge. It is sufficient to make the tear edge displaceable parallel to itself, - which can be achieved by links arranged at the tear edge.

For price reasons and above all space reasons, it is appropriate not to use different printing elements for the permanent print on the one hand and the variable data on the other hand when producing a receipt, without using the same uniform printing plant on the other side for all records of the printing plant. is suitably designed as a matrix printing unit. Such a matrix printing unit has a collection of point-like printing elements, which by activating several elements and / or multiple activation of a single element causes an alphanumeric symbol to appear. In this way, image parts in the said permanent print of the receipt can also be illustrated without further ado. In the simplest case, such a matrix printing unit consists of a row arrangement of a collection of point-like printing elements, which are assigned a specific feed of the paper strip used for receiving the symbol adapted to the function of the printing elements. In this way, with little space requirements and a very affordable printing press, you gain a great deal of freedom in the design of the records. In this respect, however, the time required for the recording plays an important role due to the multiple activation of the printing elements for illustrating a symbol in the recording of the above-mentioned permanent print. In practice, it turned out that on average five items of goods are recorded on a receipt, whereby the time required for recording in this area becomes comparable to the time required for producing the permanent print 8101704-8 l0 15 20 25 30 35 4 4 on the receipt. Without this measure taken according to the invention, according to which time is utilized which otherwise remains useless for recording the said permanent print on the paper strip, the working speed of the printing plant would be reduced by half. Thus, if the invention had not been accomplished, considerable waiting times would have arisen.

On the basis of such a matrix printing plant, it is further advantageous to interchangeably arrange an insert in a space or a pocket in the printing unit, the insert containing the printing unit's control program for the permanent pressure and, when the insert is inserted in the said printing unit space, the pressure profile is triggered according to the invention. The control program in the insert suitably consists of an integrated connection, in particular the insert contains a programmable reading memory. If the switch for the printing unit's tripping becomes effective when the receipt is torn off the paper strip, the printing works asks for the information stored in the insert, after which the entire control program stored therein is played. If another permanent print is desired on the receipt, only the previous insert needs to be removed and a new insert inserted in the printing unit's space or pocket, which insert has the corresponding correct control program. A change of the device in accordance with current requirements is thus very quickly and conveniently feasible. Only the insert needs to be replaced.

The invention will be described in more detail below with reference to the accompanying drawings. Fig. 1 shows a price calculating scale designed according to the invention.

Pig. 2 shows a schematic detail view of a printed matter used therewith. Pig. 3 shows an example of a receipt issued by the printing company. Fig. 4 shows a section through the main parts in a concrete embodiment of the printing plant.

The device shown in Fig. 1 consists of a two-part price calculating scale which is composed of a weight determination unit 11 and an evaluation unit 10.

'Both units would also in compact design lunnuavara united in a common enclosure. The weight determining unit receives a product 12, the weight of which is to be determined, on a load shell 13, which has an effect not shown in more detail. per se known measuring device, which transmits the measuring signals via a connection line 14 to the evaluation unit 10 connected to the measuring device. g The evaluation unit 10 comprises an input device 15, which has numeric keys for entering unit and unit prices as well as various instruction keys. Furthermore, an indicating device 16 is provided, which - both towards the seller's side and towards the buyer's side, has reading windows of various kinds for visual presentation of the unit price, the weight of the goods and the commodity price indicated via the counter. Finally, the evaluation unit 10 also comprises a printing unit 20 which according to Fig. 1 is incorporated in the housing. Admittedly, the printing plant 20 could also be arranged in a special unit, connected to the printing plant via an electrical connection. Tryckverket tjenartillattavgeett buy documentary receipt 19, on which the individual goods are listed with regard to prices and / or weights. Pig. 2 schematically shows the construction of such a printing plant according to the invention.

Pig. 3 shows an example of the receipt 19 issued by the printing plant.

The printing plant comprises a data carrier which in the present case consists of a long paper strip 17, which by means of a transport plant 21 is pulled off from a paper roll 18.

The transport unit 21 is provided with a feed motor 22, which provides a feed of the paper strip 17 adapted to the printing process in the arrow 23 drawn in Fig. 2, a purchase by direction. The receipt intended for production always consists of the end part of the paper strip 17, which the end of the purchase process is torn off. The housing 24 containing the printing unit has an opening 25, from which the end part 19 emerges, as shown in Fig. 2. Through an inspection window (Fig. 1) it can be checked whether the paper roll 18 is consumed. In the area of the casing opening 25 there are one or more tear edges 26, which, for example, have a sharp toothing.

If you grab the end part projecting from the opening 25 8101704-8 10 15 20 25 30 35 6 19 and pull it towards one of said edges 26, the end part is separated from the rest of the paper strip 17, whereby the unfinished receipt 19 can be taken out.

As can be seen from Fig. 3, such a receipt 19 comprises two substantially different sections 28, 29. In the exemplary embodiment shown, the receipt comprises in its head a permanent print 28, which may be composed of a company box 30, a unit strip 31. and possibly additional fixed tasks, such as a number 32 on the device. This permanent print 28 may have predefined alphanumeric and image parts.

In the exemplary embodiment shown in Fig. 3, in the company box 30, in addition to pre-given text information 34, there are also printed image parts, namely a company image emblem 35, for example a trademark for the point of sale, and decorative details, for example a company window surrounding frame 36. comprises the units intended for printing in the underlying receipt sections 29 in separate columns. This primarily includes the weight information "kilograms" in the first column, then the unit price in the intermediate column, respectively the current currency unit per kilo and finally in the last column the currency unit for the commodity price determined from the mentioned values.

On the other hand, the lower section 29 of the receipt 19 shows, arranged in rows, the individual items of the goods included in this purchase, the individual values of which are printed listed below the symbols in the unit list 3. In the exemplary embodiment shown, the first three items and the fifth item comprise goods whose product price has been calculated from the respective established weight for the product and the associated unit price. The fourth item is a unit price, where the item intended for sale is in a pre-packaged, priced item. Finally, the variable data in this section 29 includes at the foot of the receipt the final sum, which is calculated by adding the individual commodity prices in the price column 19 of the receipt.

At the printing plant shown in Fig. 2, a tent-mounted printing device 37, 33 is provided for producing a receipt 19. The pre-given information 28 associated with the receipt 19, 10 15 20 25 30 35 8101704-8 7 the pre-given information is placed on a cliché 39, which when released in cooperation with a back pressure plate 40 carries the information on the paper strip 17. The release of said device 38 takes place by means of a sensor which reacts to tear off the end part of the paper strip serving as receipt 19. .

For this purpose, each of the two tear edges 26 is resiliently arranged by the force hose spring 41 at a stop 42 in the initial position. In this case, the tear edges 26, as indicated by the arrows indicating the movement 44, are slidably guided. If one grips the end part 19 and pulls it towards one of the tear edges 26 for tearing, the tear edge is first displaced back against the action of the spring force 41, whereby the tear edge encounters an actuator 43 for a switch 45 arranged in its path of movement. the movable tear edge 26 of the end part 19, whereby this can be taken out as a receipt. In this case, however, the switch 45 has become active and sends, as indicated by the line 46, a control pulse first to the printing device 38, which via its cliché 39 applies the permanent print 28 on the paper strip 17.

At the same time, the transport authority 21 can thereby feed the paper strip a certain piece. As a result, the head in the subsequent, for the next receipt for future purchases intended piece of paper strip 17 has been completed.

Now the printing device 37 is also prepared to gradually record the coming variable data 29 on this next receipt 19 in the active connection transport unit 21.

In the exemplary embodiment of the printing device 37 shown in Fig. 2, type wheels which, in step with the printing, co-operate with a counter-surface 48 movable here, the type wheels being brought into a correct rotational position in a manner known per se via an impulse line 50 of an associated gear 49. the printing process. Via said impulse line 50, the corresponding drive motor 22 of the transport unit 21 is also stepped further correspondingly. This is done as long as goods are to be listed as individual items on the associated section 29 of the receipt intended for printing 8101704-8 l0 15 20 25 30 35 8. Finally, when the sum key is pressed on the input device 15 mentioned in connection with Fig. 1, the added final sum will be printed at the foot of the receipt.

Fig. 4 shows a preferred embodiment of the invention, which uses the same uniform printing unit 51 both for the permanent print 28 and for the recording of the variable data 29 on a receipt 19. For designation of identical components the same reference numerals have been used as in the first embodiment, which is why the present description applies to that extent. The following deviations can then be determined: The data carrier here consists of a record carrier S2 which is intended to be thermally provided with writing and whose roll lies in a plastic bowl 53. The web 52 of the data carrier is passed over an angled edge 54 on the bowl 53 to a printing plant 51, which consists of a thermal_works and matrix printing plant. From this, the web 52 passes a tear edge 26, through an opening 25 in a flap S5, which covers the entire casing 24 together with the plastic bowl 53 inserted therein and, as can be seen from the dashed position 55 ', is openable and closable to provide access to the interior of the housing when changing the roller 18 to the web 52.

The tear edge 26, which may consist, for example, of a toothed blade, has been made displaceable parallel to itself in a guide 56 and is connected to a holding member designed as a link S7. The link 57 is provided with a 1-angle curved arm 58, the pivot path of which around a bearing point 59 for the link 57 again contains the actuator 43 for a switch 45. A spring 41 also here provides a starting position for the link 57 and thus for the tear edge blade. 26, which is determined by a stop 60. Towards the spring 41, the tear edge blade 26 is displaceable in the direction of the arrow 61 shown. This displacement takes place when an end part 19 of said web 52, which projects out of the opening 25 in the closed flap É5, is moved by hand towards the tear-edge blade 26 to be cut off. As a result, the displacement 61 of the blade 26 is effected, which via the actuator 43 triggers the switch 45. As a result, as already in the first exemplary embodiment in Fig. 2, the device shown in FIG. 3 permanent pressure 28 on a future receipt already when the previous end part 19 is cut off at the tear edge blade 26 to serve as a receipt for the already completed, previous purchase. The matrix printing plant 51 comprises a collection of point-like active elements 62, which over a pivotable member 63 is pressed against the thermally sensitive web 52, which in this area runs around a roller 64. This is provided with a drive device (not shown) and provides a specific. transport of the web 52 in relation to the thermal recording activity of the elements of the die printing plant 51.

The elements 62 are in the present case arranged in a single row and lie next to each other. The row length is equal to the desired width available for recording of the web 52. Each of the elements 62 is provided for its thermal heating with electrical supply and discharge lines 65, which are electrically connected via plugs 66 or the like to control lines (not shown) on a conductor plate 67. The supply and discharge pipes 65 can be arranged in a flexible plastic flap, where they are insulated in relation to each other and in cooperation with the pressing means 63 provide for a specific position of the thermal elements 62 in relative to the roller 64. The pressing means 63 is under load of a spring 68, which provides an operative position of the thermal element 62. For insertion of the web 52 into the area of the roller 64, the pressing means 63 against spring load 68 can be pivoted back to an inactive position.

The plastic bowl 53 has a space or a pocket 69, which is intended to receive an insert 70 and becomes accessible when the flap SS 'is folded up. The insert 70 contains in its interior a programmable read-only memory 71 in which the control program for a receipt 19 permanent print 28 is stored. Plug elements 72, which are connected to the programmable read only memory, protrude from the insert 70 and when the insert 70 is inserted into the pocket 69, the plug elements 8101704-8 10 15 20 25 30 35 10 72 are connected to the inside. in the pocket arranged coupling means 73, which via wires 74 are electrically connected to conductor paths (not shown) in the conductor plate 67.

The conductor plate 67 has a collection of electrical components which are responsible for the control and operation of the die printing unit 51.

These include a control means 75, which is designed as a microcomputer and to which the programmable read-only memory 71, the switch 45 and an additional memory 76 in the form of an integrated connection are connected, in which there is size and shape of all available, numerical or alphanumeric symbols applied to the section denoted by Fig. 3 in the form of variable data. However, the outputs of a main memory counter, the evaluation means and the input device 15 are also connected to the microcomputer 75, whereby the data appearing in Fig. 1 in the display device 16 are received by the microcomputer 75 and by interrogating the memory 76 are converted to controlling the punctual element 62 of the matrix printing unit 51. By exchanging the memory 76 for another memory, the shape of the symbols required for the variable data 29 of the receipt 19 can be changed.

As can be seen from the above, the elements 62 of the matrix printing plant 51 serve to record both the permanent print 28, for example in the header of the receipt 19 in Fig. 3, and the individually different variable data in the other sections 29 of the receipt 19. the control pulse triggered via the tear edge blade 26 in the switch 45 first automatically queries the microcomputer 75 for the entire control program for illustrating the permanent pressure 28. This data is stored in the programmable read-only memory 71. The element 62 of the matrix printing unit 51 is for illustrating all images. and textual information in the print 28 operating in conjunction with a determined transport movement of the roller 64, until the work process for preparing said permanent print 28 is completed. Thereafter, the printing plant is stopped for the time being and the control is now ready to become active after the operation of the input device 15 and the weight measuring device in the weight unit 11 in Fig. 1. In this case, the microcomputer 75 cooperates with the above-mentioned components connected to the computer the store scale. The previously (shown in Fig. 4) at the sharp tear edge of the blade 26 cut off the end of the web 52 has already, when the permanent pressure 28 has been pressed, stepped out of the opening 25 in the flap 55 and could be gripped by hand. The recording of the variable data 29 on the receipt 19 could, after the entire purchase, be carried out uniformly in a single swipe, if until then data for the individual items are stored in an intermediate memory. However, it is also possible that each individual item in the purchase is printed separately on the receipt 19. The invention is useful in both cases.
