Description

DEVICE AND METHOD FOR SEPARATING PRODUCT PARTS OF A MULTIPLE PRODUCT

The invention is in the field of promotion and further processing of sheet products, especially printed products. The invention relates to a device for separating product parts of a multi-part, flat product, comprising at least one receiving unit, which forms a receptacle for receiving the product, and at least one S epari ermechani smus for separating two product parts, wherein the S epari ermechani smus a to a Positioning pivot axis in the receiving compartment to the product in the receptacle now and then from the receiving pocket out pivoting swivel module with at least one vacuum element with a suction-active element for producing a temporary suction contact with a first product part contains.

The invention also relates to a method for separating the product parts of a multi-part, flat product using the device according to the invention.

Folded printed products are characterized by a folded edge, along which the printed product is folded and forms a first and second product part. The folded edge opposite the free edges of the product parts are arranged. Folded printed products usually have to be opened at least once in the course of their further processing in order to produce further print jobs between their product parts. Products, such as newspapers, brochures, brochures, flyers, samples or other other, usually flat inserts to insert.

In order to facilitate the opening of folded products or to make it possible at all, it is customary that the one product part has a so-called pre-fold. The pre-fold is a surface portion on one of the product parts in the region of the free edge, which lies opposite the folded edge. Said surface portion is characterized in that it protrudes from the free edge of the other product part. The one product part thus forms a free area with respect to the other product part.

The prefold can be z. By attaching an asymmetric, i. on the outside, produce folded seams. Correspondingly, printed products without a prefold are usually folded in the middle or cut after folding. Such a prefold allows, for example, the one product part at the prefold, z. B. by means of a clamp or a nipple to take or fix. The two parts of the product can now be moved apart, for example with gravity support, keeping the other part of the product. In this way, the product parts can be separated and the printed product can be opened quickly and easily.

Representing a variety of patent publications, which have opening devices for the subject, which operate according to the opening principle described above, the European patent publication WO 2013/163768 Al mentioned at this point.

WO 2013/163768 Al describes a device for opening and inserting Hachen articles in a folded printed product. The apparatus includes a circulation system having a plurality of compartments movable along a closed, circular orbit about an axis of rotation. The compartments have Partial floors, which are limited in the direction of circulation of partitions. The compartments further have openings for introducing the printed products along the circumference. The compartments each contain a clamp, by means of which the prefold of a trailing product part is held on the trailing compartment wall.

The compartments are guided down a rail track, the compartment openings being moved down the outer circumference. In this process, the leading product part pivots due to gravity down to the opposite, leading compartment wall, while the trailing product part is held by the clamping legs on the trailing compartment wall. In this way, the printed product opens completely and the insert can be inserted. Producing a prefold to facilitate processing of printed products, therefore, causes a significant amount of cut waste when it needs to be removed. The cut waste must be disposed of with appropriate effort.

Furthermore, appropriate units are provided which are able to separate the prefold. In addition to ecological aspects, the additional consumption of raw material and thus the additional costs are important from a business economic point of view, without resulting in an additional benefit for the end product. If a prefold could be dispensed with in the wide-area machining process, this would mean a considerable material saving. The material savings would consequently lead to a reduction in production costs. In addition, such material savings would also help conserve resources. Furthermore, by eliminating the pre-fold, an operation could be omitted which involves the separation of the pre-fold. Since the prefold usually only serves to open the printed product, a direction would therefore be useful, which is able to open printed products without Vorfalz. However, it is to be considered that the opening of the printed products is not only a very important but also an extremely delicate process step. On the one hand, the opening and keeping open of the products should be fast and reliable, on the other hand the product should be treated as gently as possible during this process so that it is not damaged. It is therefore an object of the present invention to provide a device which is able to separate adjacent product parts of a multi-part, sheet-like product from each other so that a subsequent opening of the product can be easily performed. The purpose of the package is to be able to separate two product parts from products without prefolded products as well as from products with prefolded seams.

Ideally, the device should be designed so that an aggregate can be connected for separating two product parts from products without prefold, which is not necessary, for example, when separating two product parts from products with prefold and therefore does not have to be switched on.

The object is achieved by the features of the independent device claim 1 and the method claim 14. Further embodiments are evident from the dependent claims of the description and the drawings. In this case, features of the device can be combined with the features of the method and vice versa.

The device is characterized by the fact that the swivel module contains a swiveling body pivotally mounted about the positioning swiveling axis, and that Swivel module includes a fixed to the swivel body Anlegekörper, and the at least one vacuum element is arranged with its absorbent element on Anlegekörper, and the Anlegekörper is movable relative to the swivel body, wherein the swivel module includes at least one pneumatic element, which is in operative connection with the contact body and is designed to move the application body relative to the swivel body.

The swivel module is in particular pivotable about the pivoting body about the positioning pivot axis from a passive position into a separating position and vice versa. The passive position lies in particular outside the receiving compartment. The Separierposition lies in particular within the receiving compartment.

The term "separating" is understood to mean the separation of two adjacent product parts from a free product edge, in particular from the free product edge, which lies opposite the composite edge, forming a gap between the two product parts. The term "separating" differs from the term "opening" in that the gap created by the separation between the two product parts may be smaller than the gap created during opening of the product for inserting a side dish. Furthermore, the gap for separating the product parts can be arranged only in a portion of the product pointing to the free edge, while the gap in the opened product extends practically over the entire product up to the composite edge.

The multi-part flat products disclosed in the present patent application have at least two product parts which are connected to one another at a composite edge. The product parts are particularly flexible.

The individual product part can be single or mehrblättrig. The product parts in themselves can be connected to one another at an edge extending perpendicularly to the composite edge via a further composite edge. The composite edge may be a collar, a spine, a fold or a folded edge. The product parts may be joined together at the composite edge via a folded edge, an adhesive bond, a seam, a ring binding or a stitching, such as thread stitching or wire stitching, or via a connecting adhesive strip. Other suitable joining techniques are also possible.

The products further form an opening side which faces the composite edge. At the opening side of the products, the leaves of the product parts form free edges. "free edge" means that the leaves are not connected by a fold or otherwise.

The multi-part, sheet products can also several, nested, especially folded partial products such. As newspaper bundles include. The sub-products themselves may contain several product parts, in particular two product parts, which are connected to one another via a composite edge.

The individual product parts may contain one, two or more than two sheets. The latter can be the case, for example, if the products are folded several times.

The product can also form between the folded edge and the free edge also each have a lateral, free edge. However, it is also possible that the product forms a lateral free edge between the folded edge and the free edge on one side and a lateral folded edge on the opposite side. Such Zweifalzprodukte can be opened by means of a Vorfalzes.

The products can z. B. be folded once. Each product part can be formed einblättrig in this case. The products may be, for example, envelopes or folded sheets. The multi-part, sheet products can in particular printed products, such. As sheet, brochures, newspapers, tabloids, magazines or magazines be. The products are in particular simply folded, two-sheet printed products which form four pages.

The receiving unit may be a receiving compartment or a receiving bag. The receiving unit can also be present as a receiving channel. The receptacle corresponds to a receiving space for the product. The receiving unit contains in particular a first and a second support structure, which are spaced from each other and limit the receiving compartment. The support structures support in particular the surface sides of the product parts. Thus, the first support structure supports the surface side of a first product part and the second support structure supports the surface side of a second product part in the open position of the product. The Stiitzstruktur can z. B. as a wall, such as pocket wall or compartment wall, be formed.

The swivel module is in particular pivotable into the separating position between the first support structure and the product in the receiving compartment.

The positioning pivot axis is arranged in particular in the region of the receiving opening. The positioning pivot axis is arranged in particular in the region of the receiving opening on the first or second support structure. The positioning pivot axis is arranged in particular in the region of the Aufnahmeöff ung on the second support structure. This second support structure is trailing in particular in the conveying direction of the first support structure.

The receiving unit may form a bottom, which forms a stop for the composite edge of the inserted product or a insertion limit for the product unit. The product stands with the composite edge on the ground and is supported to the ground. The bottom can be adjustable so that the insertion or insertion depth can be adjusted and, for example, adapted to the product format. However, it can also be provided that the floor is not part of the receiving unit but is otherwise supported on the device support, which cooperates with the receiving units and supports the products on their composite edge. The receiving unit further includes a receiving opening, via which the product is introduced into the receiving compartment, and to which the free edge of the product introduced into the receiving unit is directed. The opening faces the floor in particular. The receiving unit may also include side limiting elements, such as lateral guide plates, which laterally guide or align the products. The side boundary elements thus form a lateral stop.

The receiving unit may further contain adjustment means which allow the adjustment of the side boundary elements, in particular the adjustment of the distance between the side boundary elements. This allows the distance between the side boundary elements to be adapted to different product formats. The suction-active element is characterized by a suction opening, via which a suction is generated, which is able to produce a suction contact between the suction-active element and the product part.

The suction opening of the at least one negative pressure member, hereinafter called the first lower drawer member, is in a separating position which will be described below directed in particular to the product in the receiving compartment or to a second support structure.

The vacuum element is in particular connected via a pneumatic line, in particular a vacuum line, to a pneumatic device, in particular a vacuum generating device. This generates the necessary negative pressure.

The pneumatic element of the swivel module contains, in particular, a pneumatic element which has a variable extent along a movement axis as a function of the gas pressure or gas volume in the pneumatic element. By changing the extent of the pneumatic element, the contact body can be moved relative to the swivel body. The application body is in particular movable from a waiting position on the swivel body in a contact position to the product or to the second support structure and vice versa.

As is described below, the contact body can be moved toward and away from the product in the receiving compartment or to a second support structure via the at least one pneumatic element relative to the swivel body.

The pneumatic element may be a gas-inflatable bellows body. The pneumatic element may also be a piston guided in a cylinder and piston moved by means of gas pressure. The gas is especially air. The pneumatic element is in particular connected via a pneumatic line to a pneumatic device.

The pneumatic element is controlled in particular via a negative pressure. In this case, the pneumatic element is controlled by a negative pressure generating device. The pneumatic line is in particular a vacuum line. The at least one vacuum element and the at least one pneumatic element can in this case be subjected to negative pressure via the same vacuum generating device.

According to a possible alternative solution, the pneumatic element is controlled with compressed air. The associated pneumatic device comprises in particular a compressor. According to a first embodiment, the swivel module is designed to move the contact body by means of the pneumatic element in a linear movement relative to the swivel body to the product in the receiving compartment or to a second support structure and / or away therefrom. However, according to a second embodiment, the contact body can also be fastened pivotably on the swivel body via an application swivel axle. According to this embodiment, the swivel module is designed to move the contact body by means of the pneumatic element in a swiveling motion relative to the swivel body to the product in the receiving compartment or to a second support structure now and then away from it.

The Positionierschwenkachse and Anlegeschwenkachse are according to the second embodiment, in particular at an angle, for. B. perpendicular, arranged to each other. The Positionierschwenkachse and Anlegeschwenkachse can also be parallel but offset from each other.

The separating mechanism is in particular associated with a specific recording unit. If a plurality of recording units are provided, in particular each recording unit is assigned a respective separating mechanism. According to a development of the invention, the swivel module is pivotally attached to the receiving unit via the positioning pivot axis.

According to a first embodiment, the swivel module is connected to at least one swivel bush, which is guided on an axle element, such as axle rod or axle rod. In the following, the term "rod" should generally also include the term "rod".

The swivel module is rotatably mounted on the axle via the pivot bushing. The axle element in particular has a round, such as circular, cross-section.

The swivel module may be coupled to a control member which cooperates with a particular stationary control link. The control member may include a control roller disposed outside the positioning pivot axis of the pivot module, which control roller is guidable along the control link.

The swivel module can further cooperate with a return member which exerts a restoring force on the swivel module. The restoring force is in particular a torque which acts on the swivel module. The restoring force acts on a provision of the swivel module either in its passive position or in its Separierstellung.

A change in position of the control member or the control roller relative to the positioning pivot axis through the control link causes a pivoting of the pivot module either in the direction or against the restoring force.

The return member may be designed as a torsion spring screws leather. The torsion spring may be arranged on the axle rod. The axle rod may correspond to the rotary bar described below, to which an engaging element is pivotally mounted. The rotary rod is rotatably mounted accordingly, z. B. over storage. The swivel module and the rotary rod, and with this the engaging element, are correspondingly pivotable independently of each other.

According to a second embodiment, the swivel module is rotatably connected to a rotary rod and mounted pivotally about this. The rotary rod may be coupled to a control member which cooperates with a particular stationary control link. The control member may include an outside of the axis of rotation of the rotary rod or the positioning pivot axis arranged control roller, which is guided along the control link. The control roller can be connected via a control arm with the rotary rod. The rotatability of the rotary rod on the receiving unit can be realized via a corresponding storage.

The rotary rod can cooperate with a return member, which exerts a restoring force on the swivel body and thus holds the swivel body in a passive position on the receiving unit or moves the swivel body back from the separating position to the passive position. The restoring force may in particular be a torque which acts on the rotary rod.

The rotary rod can also cooperate with a return member, which exerts a restoring force on the rotary rod and thus on the swivel module. The restoring force is in particular a torque which acts on the rotary rod. The Rückstellkralt. acts on a provision of the swivel module either in its passive position or in its Separierstellung out.

A change in position of the control member or the control roller relative to the positioning pivot axis through the control link causes a pivoting of the pivot module either in the direction or against the restoring force. The reset organ can be executed as a torsion spring screws eder. The torsion spring may be arranged on the rotary rod. The receiving unit can be pivotally mounted on the device via a pivot axis. Thus, the receiving unit, for example, with the receiving opening relative to the ground to be pivoted forward, so that the first product part due to gravity is moved to the first support structure and spaced from the back held, second product part.

The pivoting of the receiving unit can be done by a control link. Thus, the receiving unit may be coupled to a control member, such as control roller, which is guided along a particular stationary control link. The pivoting position is adjusted via a change in position of the control member caused by the control link.

According to a development of the invention, the separating mechanism comprises a further vacuum element with a suction-active element, hereinafter referred to as a second vacuum element. The second vacuum element is designed to hold the second product part by means of a suction contact against the second support structure. The suction-active element is arranged with its suction-effective opening in particular in the region of the second support structure and directed to the first support structure. The device contains according to an embodiment of the invention, an engagement with an engaging element. The engagement element is movable between the two separated product parts for the purpose of maintaining the separation of the product parts.

The engagement member is movable between the product parts to prevent re-merging of the product parts. The engagement device or the engagement element can be actuated via a control link. Thus, the engagement means may be coupled to a control member which cooperates with a particular stationary control link. By a change in position of the control member, which is triggered by the control link, the engaging element between the product parts is moved in or out of this.

The engagement means may further cooperate with a return member which exerts a restoring force on the engagement member. The restoring force acts on a provision of the engagement element either in its engagement position between the product parts or in a passive position outside the product parts.

The pivot module thus serves to provide accessibility for insertion of an engaging element between the product parts. The insertion of the engaging element serves as a preparation for a subsequent opening of the product.

The engagement device may in particular be designed as a clamping device for clamping holding the second product part to the receiving unit. The Kl emmeinrichtung may be formed in particular for clamping holding the second product part to the second support structure.

For this purpose, the engagement element is moved in the execution of a clamping leg between the product parts. In the holding position of the clamping leg cooperates with the receiving unit or the second support structure or a further clamping leg, so that the second product part is clamped or held.

The clamping leg may be pivotally mounted on a rotary rod. The rotary rod may be coupled to a control member which cooperates with a particular stationary control link. The controller may have one over one Control arm with the rotary rod control roller include, which is guided along the control link. The rotatability of the rotary rod on the receiving unit can be realized via a corresponding storage. The rotary rod can cooperate with a return member which exerts a restoring force on the clamping leg. The restoring force is in particular a torque which acts on the rotary rod and thus on the clamping leg. The restoring force acts on a return of the swivel module either in its passive position or in its clamping position.

The return member may be designed as a torsion spring coil spring. The torsion spring may be arranged on the rotary rod.

A change in position of the control member or the control roller relative to the rotational axis of the rotary rod by the control link causes rotation of the rotary rod with the clamping element either in the direction or against the restoring force.

According to a development of the invention, the at least one receiving unit in the device is circumferentially movable along a closed path of movement. The receiving unit is guided in particular along the movement path.

The first support structure according to this embodiment of the invention, in particular a leading support structure. The second support structure is in particular a trailing support structure. The first product part faces the leading support structure as a leading product part. The second product part faces the trailing support structure as a trailing product part.

The terms "leading" and "trailing" refer in the present patent application to the direction of movement of the receiving unit or conveying direction of the Products along the path of motion, as will be described in more detail below.

There may be a plurality of receiving units in the direction of movement behind the other and spaced from each other along the movement path movable.

According to one embodiment of the invention, the pivot module of the receiving unit is assigned and also along a closed path of movement synchronously with the receiving unit mitbewegbar mitbewegbar.

According to a particular embodiment, the device is designed as a rotatable around at least one axis of rotation concentricity, on which the receiving units are arranged circumferentially. The concentricity can z. B. contain one or two axes of rotation.

The concentricity can be designed, for example, as a rotational body, such as a drum. The trajectory of the concentricity is z. B. a circular path.

The pneumatic lines can be performed by the vacuum element or the pneumatic element to the axis of rotation of and 1, which is designed as a hollow shaft. The pneumatic lines can be used together with a guided in the hollow shaft central supply line with negative pressure, i. with a suction, be acted upon. The central feed line is connected to a vacuum generating device.

The negative pressure or induced draft in the pneumatic lines and consequently on the vacuum element or pneumatic element is controlled accordingly, so that the individual organs can be actuated at the right time. Such control can of course be done via an electronic control of valves. However, this is very expensive and correspondingly expensive. Therefore, a purely mechanical control of the negative pressure offers an advantageous alternative. Thus, according to a particular embodiment of the invention, the hollow shaft is formed as a control link by the rotating during operation hollow shaft caused by the rotation, temporarily frees suction ports from the central supply line to the pneumatic lines to form a temporary induced draft in the pneumatic line and closes again. This can be z. Example, be achieved by the hollow shaft is coupled with co-rotating opening and closing portions which are moved during the rotational movement of fixed access openings to the pneumatic lines over.

If both negative-pressure organs and pneumatic organs are operated with negative pressure or an induced draft, then all organs can be subjected to negative pressure via a common feed line.

The take-up units are arranged, for example, radially around the axis of rotation with radially outwardly facing receiving openings on the concentricity. The receiving units can be mounted pivotably via a receiving pivot axis relative to the concentricity.

The device may in particular be a plug-in device which is designed for opening the products and for inserting inserts between the product parts of opened products. Thus, a plug-in device embodied as a concentric run along the concentricity can contain a product feed device as well as a feed supply device. Between the product feeder and the Beil agenzuführeinrichtung the products are opened. Subsequent to the shuffle feed device, a dispensing device may be arranged, at which the product units provided with inserts are delivered to a removal device. The invention also relates to a receiving unit for a device described above for separating product parts of a multi-part, flat product. The receiving unit forms a receptacle for receiving the product. The receiving unit includes a pivoting about a positioning pivot axis in the receiving compartment for product in the receiving compartment and out of the receiving compartment out pivot module of a separating mechanism. The swivel module contains at least one vacuum element with a suction-active element for producing a temporary suction contact with a product part of a product in the receiving compartment.

Swivel module is in particular pivotally attached to the receiving unit via the Positionierschwenkachse.

Furthermore, the features disclosed above in connection with the device for the receiving unit and for the swivel module also apply to the independently loaded receiving unit. The invention also relates to a method for separating two product parts of a multi-part, flat product by means of a device described above. The method is characterized by the following steps:

Inserting a product into the receiving compartment of the receiving unit,

- swiveling the swivel module around the positioning swivel axis into the receiving compartment towards the product in the receiving compartment;

- Moving the Anlegekörpers relative to the swivel body to the product in the receptacle out;

- Generating a suction contact between the absorbent element of the vacuum element with a suction-effective element facing the first product part by means of negative pressure; - Moving back of the application body towards the swivel body and thereby separating the first product part from the second product part;

- inserting an engagement element between the two product parts;

- releasing the suction contact between the absorbent element and the product part facing it;

- Swivel back the swivel module to the positioning pivot axis out of the receiving compartment.

The pivot module is pivoted when pivoting about the positioning pivot axis in the receiving compartment in a separating position in front of the product.

The contact body is located during the pivoting of the swivel module in the receiving compartment in a retracted to the swivel body waiting position and has on reaching the Separierposition in particular a distance from the product.

The contact body is moved in or after reaching the Separierposition starting from its waiting position relative to the swivel body to the product in the receiving compartment towards its application position.

The first product part is separated when moving away the application body in its waiting position to the swivel body from the second product part.

The release of the suction contact is done in particular in the waiting position. The pivoting back of the swivel module about the positioning pivot axis out of the receiving compartment from the separating position into the passive position occurs in particular only after release of the suction contact.

According to the first embodiment, the contact body is moved in a linear movement. According to the second embodiment, the contact body is pivoted relative to the pivot body about the Anleschwivelachse. However, the pivot radius is chosen so large, in particular, that the movement of the contact body between the waiting position and the application position corresponds approximately to a linear movement.

The two-stage movement of the application body, consisting of the pivoting movement of the passive position in the Separierposition by the pivot body and the application movement from the waiting position to the application position and vice versa has the advantage that the movement pattern of the application movement can be interpreted linear or approximately linear.

This means that the separation of the product parts is effected by a linear or approximately linear movement between the application position and the waiting position. As a result, a gentle treatment of the product parts is achieved because only tensile forces are generated perpendicular to the surface side of the product parts and not parallel to this. Tensile forces which act parallel to the surface side of the product part, namely to damage the product by tearing and also lead to a shift of the product in the receiving unit. Such forces are generated, for example, when the separation of the product parts takes place via a pronounced pivoting movement.

According to the present invention, however, there is no suction contact between the first product part and the negative pressure member in both directions during the pivotal movement of the pivoting body. Such a suction contact is, as already described, only between the application position and the waiting position. According to a development of the method, the second product part, which bears against the second support structure, is held on the second support structure via a suction contact by means of an absorbent element of another vacuum element after the product has been introduced into the receiving compartment. The second vacuum organ is directed with its absorbent element in particular to the first support structure, wherein the suction-effective opening is facing into the receiving compartment.

If the Separiermodul formed as part of the receiving unit, they are moved together along the path of movement. This allows the method according to the invention to be carried out during the movement of the receiving unit along its path of movement and correspondingly during the conveyance of the products along its conveying path.

The present invention has the advantage that the product parts can be separated gently and quickly by means of a comparatively simple and robust mechanism in the form of a swivel module. The swivel module can be easily and easily attached to the take-up unit. Since the swivel module is moved with the receiving units, the product parts can be separated to save space during their promotion and then open.

Furthermore, the swivel module can be switched on by pivoting into the Separierposition only when needed. For example, if the products have a pre-fold, the swivel module does not need to be switched on and put into operation. The second product part can be retained directly without prior separation of the product parts by the swivel module by means of clamping element on Vorfalz and the product can then be opened.

In the following, the subject invention will be explained in more detail with reference to embodiments which are illustrated in the accompanying drawings. Show it: Figure 1 shows a section of Einsteckvorri rect from the side according to the

Basically, the same parts are provided with the same reference numerals in the figures. 1 shows a section of a plug-in device 101 in the form of a concentricity for opening printed products 105 with pre-fold and for inserting inserts in the opened printed products 105 according to the prior art.

The device 101 includes a plurality of receiving pockets 102 each having a leading pocket wall 110a and a trailing pocket wall 110b, which form a receptacle 109. The receiving pockets 102 are radially aligned and have radially outwardly directed pocket openings 1 13. The receiving pockets 102 are moved in the direction of movement B along a curved convex trajectory.

The printed products 105 are inserted with their folded edge 107 ahead in the radial insertion direction E through the pocket opening 1 13 in the receiving pocket 102. The printed product 105 comes with its folded edge 107 into abutment with a pocket bottom 1 1 1. The insertion depth for the printed products 105 is limited by the bottom of the pocket 1 1 1. The leading product part 106a is directed to the leading pocket wall 110a. The trailing product part 106b comes with its prefold to the trailing pocket wall 1 1 Whether to lie.

In a subsequent step, the clamping leg 1 15 of a clamping device 104 is pivoted into the receptacle 109 to the prefold and clamps or holds the trailing product portion 106 b on the prefold on the trailing pocket wall 11 Ob fixed.

The receiving pocket 102 is tilted forward due to a change in position caused by the continued movement along the path of travel. In this case, the leading product part 106a is moved by gravity to the leading pocket wall 1 10a while the trailing product part 106b remains clamped to the trailing pocket wall 110b. The printed product 105 is opened. An insert 120 can now be inserted into the opened printed product 105.

The device according to the invention is now distinguished by the fact that the receiving pockets additionally contain a saving mechanism described in greater detail below. Figures 2 to 4 show a receiving ash 2 for receiving a folded printed product 5, as it can be used for example in a plug-in according to Figure 1.

The receiving pocket 2 contains a leading in the direction of movement B pocket wall 1 Oa and a trailing pocket wall 1 Ob, which limit a receiving tray 9. The receiving pocket 2 further includes an opposite the two pocket walls 10a, 1 Ob adjustable pocket bottom 1 first

The pocket bottom 1 1 is arranged opposite a pocket opening 13, via which the printed product 5 is inserted with the folded edge 7 in the front in the receiving pocket 2. By adjusting the pocket bottom 1 1, the insertion depth can be changed and adapted to the different product formats. This is done via an adjusting device. The adjusting device is based on a two-part, trailing pocket wall 10b. The Bodenwärtige wall part on which the bottom of the bag 1 1 is arranged is attached via a slot guide on the second, opening-side wall part. The Bodenwärtige wall part and with this the bottom of the bag 1 1 is on the slot guide relative to the opening side wall portion to the pocket opening 13 toward or away from this displaced, so that the insertion depth can be adjusted. The trailing pocket wall 10b further includes adjusting means for adjusting lateral guide plates 12a, 12b, which are adaptable to the width of the printed product 5 in an opening-side area. To produce the adjustability, a slot is provided in each case in which a fastener connected to the guide plate, for. B. a screw, can be moved and locked. The receiving pocket 2 is z. B. arranged on a designed as a concentricity Einsteckvor- direction, which is rotatably mounted about an axis of rotation (not shown). The receiving pocket 2 is pivotally mounted about a fourth pivoting roller 14 of a plurality of control rollers mentioned below about a pocket pivot axis S2 on the insertion device. The fourth control roller 14 cooperates with a stationary control link (not shown). The pivot position of the receiving pocket 2 is controlled by a change in position of the fourth control roller 14 relative to the pocket pivot axis S2.

The receiving pocket 2 further includes a clamping device 4 with a clamping leg 15 for clamping the trailing product part 6b on the trailing pocket wall 10b. The clamping leg 15 is attached to a rotary rod 16 and pivotally mounted on this.

The rotating rod 16 is in operative connection with a stationary control link (not shown). For this purpose, the rotary rod 16 is coupled to a control member which comprises a second control roller 18 coupled to the rotary rod 16 via a control arm. The second control roller 18 is guided along the stationary control link.

The rotary rod 16 cooperates with a return spring 24 which is a torsion spring designed as a helical spring. The return spring 24 is arranged around the rotary rod 16 and exerts on the rotary rod 16 and thus on the clamping legs 15 a restoring force in the form of a torque.

The restoring force acts on a provision of the clamping leg 15 either in its open position or in its closed position.

A change in position of the second control roller 18 relative to the receiving pocket 2 by the control link causes rotation of the rotary rod 16 either in Direction or contrary to the restoring force. The clamping leg 15 can be controlled via the backdrop-guided second control roller 18 is pivoted between an open position and a closed position. The receiving pocket 2 contains on its leading pocket wall 10a a retainer 40. The Rücklralteeinrichtung 40 includes a retaining member 41 which is fixed to a pivot rod 42 and pivotable about this.

In order to stabilize the printed product 5 in the receiving compartment 9, the retaining element 41 is pivoted toward the trailing pocket wall 1 b via a rotation of the rotary rod 42 and presses the printed product 5 against the trailing pocket wall 10 b in a middle section. In this way, the printed product 5 can be secured during its promotion along the movement path of the receiving pocket 2 against displacement in the receiving pocket 2 or against falling out of the receiving pocket 2.

The rotary rod 42 is in operative connection with a stationary control link (not shown). For this purpose, the rotary rod 42 is coupled to a control member which comprises a third control roller 44 coupled to the rotary rod 42 via a control arm. The third control roller 44 is guided along the stationary control link.

The rotary rod 42 cooperates with a return spring 43 which is a torsion spring designed as a helical spring. The return spring 43 is arranged around the rotary rod 42 and exerts on the rotary rod 42 and thus on the retaining element 41 a restoring force in the form of a torque.

The restoring force acts on a provision of the retaining element 41 either in a passive position or in a retaining position. A change in position of the third control roller 44 relative to the rotary rod 42 through the control link causes rotation of the rotary rod 42 either in the direction or against the restoring force. The retaining member 41 can be so controlled via the gate-guided third control roller 44 between a passive position and a Rückhaltestel development about the rotary rod 42 are pivoted.

The receiving pocket 2 also includes a separating mechanism 3 according to a first embodiment, which will be described below. However, it should be emphasized at this point that the receiving pocket 2 may include a separating mechanism 53 according to the second embodiment described below instead of a separating mechanism 3 according to the first embodiment (see FIGS. 7a and 7b).

The separating mechanism according to the first embodiment according to FIGS. 2 to 6 comprises a pivoting module 20 with a pivoting body 21 and a locating body 22. Pneumatics 19 in the form of vacuum lines for pneumatic elements 28 and for a first vacuum element 26 are guided towards the pivoting body 21. The pivoting body 21 is pivotally mounted about a positioning pivot axis S l.

For this purpose, two pivot bushings 23 are arranged on the swivel body 21, via which the swivel module 20 is mounted on a rotary rod 16. The pivot bushes 23 are guided on the rotating rod 16. The swivel module 20 is rotatably mounted on the pivot rod 16 via the pivot bushes 23.

The swivel module is coupled to a control member which cooperates with a stationary control link (not shown). The control element comprises a first control roller 25, which is arranged outside the positioning pivot axis S1 and which is guided along the control link. The pivot module 20 acts together with a restoring spring 17, which is a torsion spring designed as a helical spring. The return spring 17 is arranged around the rotary rod 16 and exerts on the swivel body 20 a restoring force in the form of a torque.

The restoring force of the return spring 17 acts on a provision of the pivot module 20 either in its passive position or in its separating position.

A change in position of the first control roller 25 relative to the positioning pivot axis Sl by the control link causes a pivoting of the pivot module 20 either in the direction or against the restoring force. The swivel module 20 can be pivoted so controlled by the gate-guided first control roller 25 between a passive position and a separating position. The contact body 22 is a plate-shaped element, which is connected via two spaced-apart pneumatic members 28 with the pivot body 21 (see also Figure 5a to 5h). The pneumatic elements 28 each comprise a pneumatic element 29 in the form of a hollow bellows. About a vacuum line can now be applied to the Faltenbai ghohlkörper 29 a negative pressure. By applying a negative pressure by means of suction pulls the bellows ghohlkörper 29 together. By terminating the induced draft this again expands along its longitudinal axis L.

The expansion of the bellows hollow body 29 causes the contact body 22 together with the absorbent member 27 of the vacuum member 26 in the separating position in a linear movement from the pivot body 21 away to the printed product 5 and the second pocket wall 1 Ob is moved.

Between the two pneumatic organs 28, a first negative pressure member 26 is arranged, which with its suction-active element 27 with suction port on Contact body 22 is arranged. The suction opening is directed away from the swivel body 21 to the print product 5 in the separating position. The suction-active element 27 is connected via a bellows hollow body 32 with the swivel body 21 and with the guided to the swivel body 21 vacuum line 19. The bellows hollow body 32 serves to compensate for changes in distance between the contact body 22 and the swivel body 21 by expansion and compression of the bellows hollow body 32.

The associated operating method for separating two product parts 6a, 6b of a printed product 5 without prefold according to the first embodiment will now be described in more detail below with reference to FIGS. 5a to 5h.

At the beginning of the process, a printed product 5 is inserted into the receiving pocket 2 analogously to FIG. At this time, the swivel module 20 is in a passive position outside the receiving compartment 9 of the receiving pocket 2, as shown in Figure 3 and 5a and 5b.

The leading product part 6a of the inserted printed product 5 points to the leading pocket wall 10a and the trailing product part 6b points to the trailing pocket wall 10b.

At the second negative pressure member 30, which is arranged in the region of the trailing pocket wall 10b, a negative pressure in the form of a induced draft is applied. The trailing product part 6b enters into suction contact with the absorbent member 31 of the second negative pressure member 30 and is thus held on the trailing pocket wall 10b.

For separation of the product parts 6a. 6b, a negative pressure in the form of a suction draft is now applied to the pneumatic elements 28. The bellows hollow body 29 contracted and the application body 22 is retracted to a waiting position to the pivot body 21 out (see Figure 5c).

The swivel module 20 is pivoted via the swivel body 21 out of its passive position into the receiving compartment 9 between the leading pocket wall 10a and the printed product 5 in a separating position towards the printed product 5 (see FIG. 5d). The pivoting operation is effected by a change in position of the first control roller 25 relative to the positioning pivot axis Sl, which triggers the pivoting movement of the pivot module 20. The change in position of the first control roller 25 is effected by the control link.

The above-described moving back of the application body 22 in its waiting position is done during and preferably before the swiveling process. By moving back the Anlegekörpers 22 in its waiting position on the pivot body 21 space is created, which is required for the non-contact pivoting of the pivot module 20 on the printed product 5 in the receiving compartment 9 inside. This is of great importance insofar as the space available in the area of the receiving pocket 2 is tight and only a small amount of space is available for the operation of a swivel module 20.

The application body 22 is now positioned with its suction-active element 27 in waiting position in front of the printed product 5 at a distance to this when taking the Separierposition (see Figure 5d and Figure 2 and 4). After taking the separating position in front of the printed product 5, the induced draft in the pneumatic elements 28 is reduced or adjusted. The bellows hollow bodies 29 expand due to the pressure increase along their longitudinal axis L, as a result of which the contact body 22 is moved into a contact position in a linear movement towards the leading product part 6a (see FIGS. 5c and 6a). The contact position is designed so that the leading product part 6a enters into suction contact with the contact body 22 by applying a suction pull on the suction-active element 27 of the first vacuum element 26 (see FIGS. 5e and 6a). In a subsequent step, a suction is again applied to the pneumatic members 28, whereby the Faltenbal hollow body 29 along its longitudinal axis L contract again and the application body 22 is moved in a linear movement back to the pivot body 21 back to its waiting position (see Figure 5f and 6b ).

In this process, the leading product part 6a is also moved in the direction of waiting position and separates from the trailing product part 6b.

The previously held in the open position clamping leg 15 of the clamping device 4 is now pivoted by actuation of the second control roller 18 via a control link (not shown) in a clamping position (see Figure 5g).

Here, the rotary rod 16 is rotated, so that the clamping leg 15 is pivoted into the receiving compartment 9 between the two product parts 6a, 6b to the trailing product part 6b out. The clamping leg 1 5 clamps the subsequent product part 6b on the trailing pocket wall 1 Ob fixed.

As soon as the trailing product part 6b is clamped by the clamping leg 15 on the trailing pocket wall 10b, the induced draft on the first negative pressure member 26 is reduced or adjusted, so that the suction contact between the leading product part 6a and the first suction-active element 27 is released again.

The swivel module 20 is now pivoted back out of the separating position into the passive position outside the receiving pocket 2 via the stage-controlled first control roller 25 (see FIG. 5h). The induced draft on the second vacuum element 30 can now also be reduced or adjusted, so that the suction contact between the second absorbent element 31 and the trailing product part 6b dissolves again.

The clamping element 1 5 now clamps on the one hand the trailing product part 6b on the trailing pocket wall 1 Ob firmly. On the other hand, the clamping element 15 also acts as a separating element, which maintains the separation of the two product parts 6a, 6b. The separation process is completed.

The printed product 5 can now be opened, for example, by pivoting the receiving pocket 2 about the pocket pivot axis S2. The receiving pocket 2 is pivoted in such a way that the leading product part 6a moves away from the trailing product part 6b with the aid of gravity.

The sawing mechanism 53 according to the second embodiment according to FIGS. 7a and 7b can, as already mentioned, be part of a receiving pocket 2, as shown and described in FIGS. 2 to 4, analogously to the first embodiment. The separating mechanism 53 also comprises a swivel module 70 with a swivel body 71 and a contact body 72. Pneumatic lines 69 in the form of vacuum lines for the pneumatic elements 78 and the first vacuum element 76 are guided to the swivel body 71. The swivel body 71 comprises two swivel bushings 73, which are guided on the swivel rod 66. The swivel module 70 and the swivel body 71 is rotatably mounted on the pivot rod 66 via the swivel bushes 73.

The pivot module 70 is coupled to a control member which cooperates with a stationary control link (not shown). The controlling body comprises - DJ -

analogous to the first embodiment, a control roller arranged outside the positioning pivot axis S1, which is guided along a control link (not shown). The pivot module 70 acts together with a restoring spring 74 which is a torsion spring designed as a helical spring. The return spring 74 is arranged about the rotary rod 66 and exerts on the swivel body 70 a restoring force in the form of a torque. The restoring force of the return spring 74 acts on a provision of the pivot module 70 either in its passive position or in its separating position.

A change in position of the control roller relative to the receiving pocket by the control link causes a rotation of the pivot module 70 either in the direction or against the restoring force. The swivel module 70 can thus be controlled via the gate-guided control roller controlled between a passive position and a separating position.

According to this embodiment, the contact body 72 is designed as a pivoting arm, which is mounted pivotably on the pivoting body 71 about an application pivot axis S3. The application pivot axis S3 is aligned perpendicular to the positioning pivot axis Sl.

A pneumatic element 78 is arranged on the swivel module 70 at a radial distance from the application swivel axis S3. The pneumatic element 78 contains a pneumatic element 79 in the form of a bellows hollow body, which connects the contact body 72 with the pivoting body 71. The pneumatic element 79 is connected to the swivel body 71 to a guided to the swivel body 71 pneumatic line 69. The pneumatic line 69 is a vacuum line, via which a bellows in the form of a suction can be applied to the Faltenbalghohl- body 79. By Applying the negative pressure or induced draft pulls the bellows hollow body 79 together. By ending or reducing the negative pressure or induced draft, this expands again along its longitudinal axis L. In addition, a first vacuum element 76 is arranged at a radial distance from the contact swivel axis S3, which is arranged with its suction-active element 77 with suction opening on the contact body 72. The mammal opening is directed away from the swivel body 71 to the printed product 5 or to the trailing pocket wall. The suction-active element 77 is connected via a bellows hollow body with the swivel body 71 and with a guided to the swivel body 71 pneumatic line 69 in the form of a vacuum line. The bellows hollow body serves to compensate for changes in distance between the contact body 72 and the pivot body 71 by an expansion and compression of the bellows hollow body.

According to this second embodiment, before and / or during the pivoting of the pivot module 70 in the receiving compartment of the receiving pocket to the pneumatic organs 78 also a negative pressure in the form of a induced draft is applied. The Faltenbalghohlkörper 79 are thereby pulled together and the contact body 72 is pivoted about the Anlegeschwenkachse S3 in a waiting position for the swivel body 71 out.

The assumption of the waiting position during pivoting of the swivel module 70 also allows the above-discussed contactless pivoting of the swivel module 70 past the printed product into the receiving pocket. The application body 72 is at the taking of the separating position by the pivot module 70 in its waiting position spaced from the printed product 5 (see Figure 7a).

After taking the separating position in front of the printed product 5, the negative pressure on the pneumatic element 78 is reduced or adjusted. The bellows hollow body 79 expands by the pressure increase along its longitudinal axis L, whereby the application body 72 is pivoted about the Anleschwivelachse S3 to the leading product part 6a out in a contact position. Due to the radial distance between the application pivot axis S3 and the suction-active element 77 and due to the small pivot angle, the movement of the suction-active element 77 is approximately linear (see FIG. 7b).

The application position is designed such that the leading product part 6a undergoes a suction contact with the contact body 72 by applying a suction pull on the suction-active element 77 of the first vacuum-pressure member 76.

In a subsequent step, a negative pressure in the form of a suction is again applied to the pneumatic member 78, whereby the Faltenbalghohlkörper 79 along its longitudinal axis L contracts again and the contact body 72 is pivoted about the Anleschwwenkachse S3 back to the swivel body 71 toward its waiting position.

In this process, the leading product part 6a is separated from the trailing product part.

The hitherto held in the open position clamping leg 65 of the Kl emmei device 54 is pivoted by an actuation of the second control roller via a control link (not shown) in a clamping position. Here, the rotary rod 66 is rotated, so that the clamping leg is pivoted in the receiving compartment between the two product parts to the trailing product part. The clamping leg 65 clamps the subsequent product part to the trailing pocket wall.

As soon as the trailing product part is clamped by the clamping leg 65 on the trailing pocket wall, the negative pressure at the first pressure member 76 is reduced or adjusted so that the suction contact between the absorbent member 77 and the leading product part 6a dissolves again.

The swivel module 70 is now pivoted again via the gate-controlled control roller from the separating position into the passive position outside the receiving pocket. The separation process is completed.

The printed product 5 can now be completely opened, for example by pivoting the receiving pocket about a pocket pivot axis by means of gravity.

If the printed products 5 now have a prefold, then the pivot module 20, 70 according to the first and second embodiments does not have to be activated and remains in its passive position. It is merely the clamping device actuated by the pivoted into the receptacle clamping leg 15 analogous to the example according to Figure 1 without preceding separating the product parts 6a, 6b the trailing product part 6b clamped at its prefold on the trailing pocket wall 10b.
