Description

Binding machine for the application of bunch of perforated strips to sheets and semi-finished products for the production of

Issue Paper Tape

The invention is based on a staple strip machine for applying staple perforated strips to sheet material with a staple strip supply device, a feed device and an application device, the staple strip being movable in the longitudinal direction from the staple strip supply device by positive engagement of the feed device in the staple strip to the application device.

In the following, sheet goods are referred to as folded or unfolded paper or plastic sheets, cardboard boxes or other sheet-like documents which are to be provided with a perforated strip for filing.

There is already a stapling tape machine according to the preamble of claim 1, which is provided for staple strips with double perforation. After the sheet material has been inserted into the application device, a release device is actuated, which leads to a tack strip of a predetermined length being applied to the sheet product. To transport the stitching tape material to the sheet material, a feed device is provided, which consists of a spiked roller and whose spike-shaped pins engage in transportation holes of the stitching tape material. When a triggering switch is actuated, the spiked roller is rotated by a predetermined angle so that the stitching strip lies on the sheet material in the required length and can be connected to it. It is thus possible to apply staple perforation strips for double perforation to the edge area of sheet material with the known staple strip machine. Binding strips with other types of holes, for example four-hole punching, must be applied manually. This is a considerable disadvantage in the handling of staple strips for sheet goods, which are intended for storage by means of different types of holes.

The invention is therefore based on the object of providing an automatic strip dispenser with which various types of holes can be applied to sheet material.

To achieve this object, the automatic stapling machine according to the invention has means which control the feed device in such a way that the appropriate length of the feed can be generated for at least two different types of holes.

For this purpose, it is expedient that the stitching tape material used is prepared in such a way that the holes are arranged on adjacent sections of the stitching tape material in such a way that the standard-compliant distances are maintained, for which reference is also made to the exemplary embodiment.

In a preferred embodiment of the invention, the feed device is controlled in such a way that, for example, for the application of a tack hole strip with double perforation, the spiked roller, which in this case acts as a feed device, makes a half turn, while when applying a stitch hole strip with a quadruple punch. Perforation on sheet goods the spike roll a whole Revolution. It is thus advantageously possible to apply staple perforated strips with double perforation and quadruple perforation to the edge areas of sheet goods. Manual work or the use of two different automatic tape dispensers for different types of holes is therefore no longer necessary.

The invention further relates to a semifinished product for the production of stapled perforated strips, consisting of tape material with filing holes successively made in the direction of the longitudinal extent in repeating units.

A known semi-finished product for the manufacture of staple strips comprises a strip material with filing holes successively made in the direction of the longitudinal extent in repeat units for double punching for the formats A 4, A 5 and A 6 according to DIN 821. For this purpose, the filing holes are on one side of the strip material with a hole center distance of 80 mm with a hole diameter of 5.5 mm. The length of the repetition unit, ie the length of the stitching strip for a double punch, is approximately 110 mm. At certain intervals, transport holes are made in the longitudinal center of the strip material for engaging a spiked roller of an automatic strip machine. A double-sided adhesive strip with a protective film is applied to the longitudinal edge of the tape material opposite the filing holes. The previously known semi-finished product for the production of staple strips for double punching is fed into a staple strip machine by means of a spiked roller, cut off at the intervals of the repeating units and onto the A 4, A 5 and A 6 format edge area of a piece of writing is applied by means of the double-sided adhesive tape strip.

It is also known to design individual stitching strips with stitching holes for quadruple punching for A4 format according to DIN 821. There are filing holes on the edge at a distance of 80 mm from one another on the stapling strip of a certain length, which is applied to the A4 material using an adhesive tape strip.

It is true that the automatic staple strip can be used to apply perforated strips for double perforation to the edge area of documents. Prepared stitching strips with four holes must still be applied manually. This is a considerable disadvantage in the handling of staple strips for documents which are intended to be stored by means of different types of perforations.

In order to improve the semifinished product for the production of stitching tape strips in such a way that stitching tape strips with the perforation type quadruple perforation can also be mechanically applied, it is further provided that the filing holes on the strip material are divided into repetition units each consisting of four successive filing holes, the distance between the filing holes is set up within a repeating unit in accordance with a quadruple perforation. In this way, stapled perforated strips with a quadruple perforation can be produced as semi-finished products and mechanically applied to the edge area of documents. In a further embodiment of the invention, the spacing of the filing holes within a repetition unit is set up in accordance with one quadruple perforation and two double perforations. This makes it possible to process staple strips with double perforation and with quadruple perforation simultaneously or immediately in succession or to apply them to the edge areas of documents, since according to the invention a repetition unit contains one quadruple perforation and at the same time two double perforations. Depending on the use, either a full repetition unit as a quadruple perforation or two half repetition units as stapling tape strips, each with a double perforation, are cut off from the strip material. The separate stocking of tape material for the production of tack strips with double perforations and and with quadruple perforation, as well as completely cut tack strips with a quadruple perforation is no longer necessary.

Further advantageous embodiments of the invention result from the further subclaims.

Embodiments of the automatic tacking tape machine and the used stitching tape strips according to the invention are illustrated with the aid of drawings. Show

FIG. 2 shows a schematic top view of the automatic strip dispenser, FIG. 3 shows a schematic illustration of sheet goods for insertion in the automatic strip machine,

Figure 4 is a schematic plan view of a portion of a stitching strip in a first embodiment and

Figure 5 is a schematic plan view of the semifinished product for the production of stitching strips in a second embodiment.

In FIG. 1, an automatic staple strip 1 is shown schematically in a sectional view. A stitching tape strip material 50 of the first embodiment is guided from a stitching tape supply device 3 via a deflection roller 4 and a guide device 6 to a feed device 48 and passed on to an application device 49. A roll serves as a stapling tape supply device 3, on which the staple tape material 2 is wound and inserted into the guide plate. The roller is fastened by means of a knurled screw 5. The feed device 48 consists of a spiked roller 8, which has pins 10 at regular intervals, which engage in transport holes 43 of the tack strip material 50. The feed device 48 is driven by a motor 26. For better guidance of the stitching tape strip material 50, a pressure bracket 12 which is spring-loaded in the direction of the spike roller 8 and which supports the positive fit between the transport holes 43 of the stitching tape strip material 50 and the pin 10 of the spike roller 8 is arranged on the opposite side of the stitching tape strip material 50. In particular, the stitching tape tape material 50 is skipped on the Spiked roller 8 prevented. The pressure bracket 12 is designed to be pivotable, so that the stitching tape strip material 50 can be inserted more easily.

The application device 49 consists of a stamp 14 on which the sheet material 35 (not shown in FIG. 1) is placed. In order to ensure that the sheet material 35 is placed in the correct position, the stamp 14 has contact rails 29 and 30 to which the sheet material 35 is placed. By pressing one not shown

Switch is now fed the stitching tape strip material 50 in the longitudinal direction by means of the feed device 48, so that it comes to lie above the sheet material 35. Once the required length of the stitching strip 2 has been reached, the pressure plate 16 is lowered in the direction of the stamp 14, the pressure plate 16 being arranged above the stamp 14 provided with the sheet material 35 and with the stitching strip 2, so that the stitching hole located above the sheet material 35 - Strip 2 is pressed firmly onto the sheet material 35. With the knife 18, which is arranged at the end of the application device 49, which faces the feed device 48, the part of the stitching tape 2 lying on the sheet material 35 is then separated from the stitching tape strip material 50. The pressure of the printing plate 13 on the stamp 14 and the sheet thereon would be 35 with the stitching tape 2, fixing the stitching tape 2 on the sheet material 35 by means of the adhesive strip 41 located on the stitching tape 2.

The feed device 48 in the form of the spiked roller 8 generates a corresponding feed, depending on the desired number of holes, so that the desired number of holes is reached becomes. The user can thus choose whether the sheet material 35 is to be provided with a double perforation or a quadruple perforation. The desired number of holes can be entered by pressing an appropriate button or by setting a rotary switch. If double perforation is desired, only the feed of half a turn of the spiked roller 8 is generated. If, on the other hand, quadruple perforation is desired, then the spiked roller 8 makes a complete revolution in order to achieve the required length of the stitching strip 2. For this purpose, a control device 27 is provided in the automatic strip dispenser 1, which is connected to the motor 26 as the drive device of the feed device 48 and controls the corresponding size of the angle of rotation of the spiked roller 8 and thus the feed length depending on the input of the user. This can happen, for example, in that the motor 26 is designed as a stepper motor and the control device 27 specifies the number of motor steps required for the corresponding length of the feed. It is also possible that the control device has one or more sensors that measure the angle of rotation of the spiked roller 8. The operation of the motor 26 is influenced by the control device 27 in accordance with the measurement result and the angle of rotation resulting from the specification of the user.

In further embodiments of the invention, it is also possible to implement other types of holes. In addition to the double and quadruple perforation already described, a sixfold perforation can also be realized, which in the exemplary embodiment described would require a one and a half turn of the spiked roller 8. As a rule, the tape strip material 50 has a protective film 21 when it is unwound from the tape supply device 3, which must be removed before the tape strip 2 is applied to the sheet material 35. The protective film 21 covers the adhesive strip 41 of the stitching tape 2, which - if it were exposed - would hinder the transport of the stitching tape strip material 50. To pull off the protective film 21, a hold-down device 22 is provided on the automatic tab strip dispenser 1, over which the protective film 21 is guided and is pulled off from the stitching tape strip material 50 by means of rollers 24 and 25 arranged opposite one another. In order to maintain the protective effect of the protective film 21 for as long as possible, the device for pulling off the protective film is arranged between the advancing device 48 in the form of the spiked roller 8 and the application device 49.

In a further embodiment, the pressing of the stitching strip 2 of the sheet material 35 can also be achieved by the movement of the stamp 14 and the pressure plate 16 directed against one another or by the movement of the stamp 14. A guide device 20 is provided in the automatic strip dispenser 1 for moving the stamp 14.

In FIG. 2, the automatic tape dispenser 1 according to the invention is shown schematically from above. The stamp 14 with the contact rails 29, 30 to which the sheet material 35 is placed can be seen. Above the stamp 14, the pressure plate 16 is arranged, which clamps the sheet material 35 arranged on the stamp 14 with the support surface 28 with the stitching strip 2. An example of such a sheet material 35 is shown with reference to FIG. 3. A folded sheet material 35 can be seen, for example a technical drawing 35, which has the edges 36 and 37, the folding edge 36 being intended to be provided with a perforated strip 2 for filing. The sheet material 35 is now applied with the edges 36, 37 to the systems 30 and 29 for attaching the stitching strip.

For a better understanding of the invention, FIG. 4 schematically shows a stitching tape strip material 50 for forming individual stitching tape strips 2 in a view from above. The tack hole strip 2 has transport holes 43 into which the spike-shaped pins 10 of the spike roller 8 engage in a form-fitting manner. The tack hole strip 2 also has an adhesive strip 41 which - before the tack hole strip 2 is brought into connection with the sheet material 35 - is still covered with a protective film 21, not shown here. The tack hole strip 2 furthermore has holes 45 which are intended to be used to staple off the sheet material 35 provided with the tack hole strip 2. The holes 45 are made at the intervals provided for the sizes A6, A5 or A4 in the stitching tape 2. The stitching tape strip material 50 consists of sections 47 which form the individual stitching tape strips 2 and, arranged in a row, give the total length of the stitching tape strip material 50. If double or quadruple perforation is desired in accordance with the requirements of the user, then one or two sections 47 or stapling strips 2 are required for the sheet material 35 and are provided by the spike roller 8 by a corresponding feed length. The tack hole strip 2 is prepared in such a way that the tack holes 45 of each segment 47 die have the required clearances for double and quadruple punching. Each section 47 has two pairs of stitching holes 45, one stitching hole 45 of the pair of stitching holes being provided for the double punching and the other stitching hole 45 for the quadruple punching. When the stitching holes 45 in FIG. 4 are numbered from top to bottom, starting with one, the first, third, sixth and eighth stitching holes 45 are for the quadruple punching and the second, fourth, fifth and seventh stitching hole 45 are for the double punching intended.

The automatic tape dispenser 1 can be provided flexibly for different types of holes and both as a stand-alone device and for installation in an automatic folding machine.
