[0001] Title: Combination of a device for providing packaging cushioning material and a machine frame

[0002] Description

[0003] The invention relates to a combination of a device for providing packaging cushioning material and a machine frame.

[0004] It is previously known that the aforementioned devices for providing packaging cushioning material are arranged on a machine frame in order to provide packaging cushioning material from an elevated position relative to a support surface. Based on this, the present invention is based on the object of providing a combination of a device for providing packaging cushioning material and a machine frame of the aforementioned type with user-friendly operability and usability.

[0005] This object is achieved according to the invention by a combination of a device for providing packaging cushioning material and a machine frame with the features of claim 1. The combination comprises a machine frame with a stand section for positioning the machine frame on a base and a receiving section for receiving and holding the device on the machine frame. According to the invention, an adapter part is provided which, on the one hand, is or can be detachably connected to the device and, on the other hand, is detachably connectable to the receiving section. The detachable connection between the adapter part and the receiving section comprises a snap-in connection.

[0006] According to the invention, the device is detachably connected to the machine frame by means of the adapter part, resulting in the assembly according to the invention. A detachable connection of the adapter part to the machine frame is realized via the aforementioned snap-in connection. It is thus possible, in a user-friendly manner, to fasten the device to the machine frame, preferably without the aid of special tools or additional fastening means, and to remove it from the machine frame by releasing the snap-in connection. It is conceivable here that the device is held to the machine frame via one or more snap-in connections.

[0007] The device can, for example, be designed for on-demand production of packaging cushioning material. The device for providing packaging cushioning material can, for example, be a cushioning conversion machine with which a flat, web-shaped starting material made of paper is converted into a three-dimensional packaging cushioning material by crumpling, compressing and / or embossing. However, it is also possible for it to be a cushioning conversion machine with which a flat, web-shaped and tubular starting material made of plastic is converted into a three-dimensional packaging cushioning material in the form of an air cushion by inflating it. The starting material can, for example, be provided wound up on a roll. However, it is particularly preferred if the starting material is present in a stack of a zigzag-folded starting material.The device may further comprise a separating device for producing sections of packaging cushioning material with a desired discrete length. The separating device may be a cutting device or a tearing device. The latter preferably cooperates with a starting material having perforation lines.

[0008] Advantageously, the machine frame is universally usable for a wide variety of devices. The adapter part forms a universal interface between a device and the machine frame. Any device with a mounting option for the adapter part or with such an adapter part can be releasably connected to the machine frame via the snap-in connection. The adapter part can be connected to the device in any desired manner.

[0009] In an advantageous development, the locking connection is formed by the interaction of a rear-engaging region and a prestressed rear-engaging region, one being arranged near the adapter part and the other near the receiving section of the machine frame. This is technically easy to implement. The rear-engaging region can be formed by an opening, a recess, or a projection, and the rear-engaging region can be formed by a spring-biased locking element or snap element. This is technically easy to implement and robust in operation.

[0010] The engaging area can be brought out of engagement with the engaging area against the preload by means of a manually operable operating element, preferably a push button, a rotary knob or a slide, so that the locking connection can be released and the adapter part can be detached and removed from the receiving section. In this way, operation is simplified. The adapter part can be detached from the receiving section in a simple manner and without the aid of special tools. The device arranged on the machine frame can be removed from the machine frame, for example for maintenance purposes, to change the device or for repairs.

[0011] In an advantageous development, an engagement region is formed on the adapter part in addition to and spaced from the locking connection for positively hooking the adapter part onto the receiving section and thus for positioning the adapter part on the receiving section. The engagement region enables positioning of the adapter part on the receiving section in a predetermined position for subsequent locking of the adapter part to the receiving section.

[0012] The engagement region of the adapter part can have an angle piece, a tab, or a projection for positively hooking and positioning the adapter part on the receiving section. The engagement region can be formed integrally with the adapter part or as a component attached to the adapter part. Furthermore, the engagement region can comprise one or more regions that can be hooked into the receiving section. All of this is easily implemented.

[0013] Preferably, the receiving portion has a recess for positively hooking the engagement region of the adapter part. The recess can be formed as a through-hole in the receiving portion or in the form of an eyelet or the like.

[0014] In an advantageous further development, the adapter part is designed like a portal and comprises two horizontally opposed side walls and an upper wall connecting the side walls. With a portal-like design, the adapter part can preferably be manufactured in a simple manner as a formed part, in particular as a bent sheet metal part and / or a stamped part. This allows for material and weight savings compared to a solid or built-up form.

[0015] Preferably, the locking connection is formed on one side wall of the portal-like adapter part, and the engagement area for positively hooking the adapter part onto the receiving section and thus for positioning the adapter part on the receiving section is formed on the other side wall. This has proven to be advantageous in terms of handling.

[0016] The engagement area of ​​the adapter part, which is formed particularly in a side wall of the portal-like adapter part, preferably serves as a pivot bearing with some play. This allows the adapter part to be pre-positioned on the receiving section and subsequently locked to the receiving section by pivoting the adapter part in the direction of the receiving section.

[0017] An opening or recess can easily be formed in a side wall of the portal-like adapter part as a grippable area for forming the locking connection. The adapter part is thus simply designed and can be manufactured with little effort.

[0018] In an advantageous further development, at least one projection is formed on a free end of the adapter part in the region of the locking connection, in particular the side wall of the adapter part, which projection can engage in a positioning recess in the receiving section. This enables the adapter part to be locked to the receiving section in a proper operating position. One or more, preferably two, three or four projections can be provided on the adapter part. To accommodate the projections, the positioning recess can be designed in the form of a depression or a through-opening in the receiving section.

[0019] In an advantageous development, the receiving section is arranged on the stand section so that it can pivot about a horizontal pivot axis and can be locked in any pivot position, in particular by means of a locking member. The device arranged on the receiving section can be pivoted into different operating positions depending on the situation and secured to the stand section. The pivotability of the receiving section proves to be advantageous, for example, when containers of different sizes are to be filled with cushioning material. A handle can also be attached to the receiving section for pivoting.

[0020] In an advantageous development, the receiving section is displaceably held on the upright section via at least one slotted guide. Advantageously, the slotted guide can be dispensed with complex components and provides a robust and low-maintenance option for guided movement of the receiving section on the upright section. In particular, the slotted guide comprises one or more linear or arcuate slots, which are formed in particular on sides of the receiving section facing the upright section or, alternatively, on the upright section.

[0021] In particular, it can be realized that the

[0022] The receiving section can be mounted in two orientations, with the base wall being positioned at the top and at the bottom relative to the walls. Depending on the orientation of the receiving section on the stand section, the distance of the device from the support surface can be influenced. Furthermore, the pivoting position of the receiving section on the stand section can be adjusted for user-friendly or necessary handling.

[0023] In an advantageous development, the receiving section has two parallel and spaced-apart, in particular vertical, walls for mounting the receiving section to the support section, and a base wall connecting these two walls for receiving the adapter part. The receiving section can be manufactured as a formed part. Alternatively, the walls can be detachably or permanently attached to the base wall.

[0024] In this case, at least one of the above-mentioned guide rails can be formed in each of the two parallel and spaced-apart walls. This provides a degree of freedom in the arrangement of the receiving section on the upright section. The receiving section can also be pivotable relative to the upright section and guided along the guide rails.

[0025] In an advantageous development, the receiving section is designed to be height-adjustable relative to the support surface on the stand section, wherein the receiving section can preferably be mounted on the stand section at different distances from the support surface. This provides an adjustment option for specifying the distance of the device from the support surface, and a pivoting position of the receiving section is preferably adjustable.

[0026] The support section can also be adjustable in length, particularly by means of telescopic hollow profiles. The height of the support section relative to the support surface is thus adjustable.

[0027] A coupling part can be arranged between the upright section and the receiving section to bridge the gap in the horizontal direction, in particular to adapt the receiving section to different widths of upright sections. By providing coupling parts, the receiving section can always be manufactured in the same design and can, for example, be connected to differently dimensioned upright sections.

[0028] In an advantageous development, the machine frame has a material receiving device for a starting material to be treated, in particular for a stacked flat material made of paper, cardboard or plastic, wherein the material receiving device is designed to receive the starting material, in particular in or on a means of transport, in particular a pallet, a roll or a container. The starting material is preferably designed as a continuous material. The material receiving device can be arranged on the stand section. The material receiving device is preferably arranged on a side of the stand section facing away from the direction in which the packaging material is discharged from the device. The material receiving device on the machine frame can have a recessed area for inserting a means of transport or a support surface for the starting material.The support surface may be inclined towards the stand section so that a stack of the starting material or a transport means is received inclined towards the stand section and the risk of the starting material falling out of the material receiving device is reduced.

[0029] Furthermore, the material receiving device can have two limiting struts which extend along the stand section and are horizontally spaced from one another for laterally limiting the starting material, wherein a horizontal distance between the limiting struts can be adapted to a width of the starting material or its means of transport, in particular in that the limiting struts can be mounted at different positions in the horizontal direction on the stand section. The horizontal distance between the limiting struts can be adjusted to 200 mm, 300 mm, 400 mm and 600 mm, for example. Stacked starting material can be kept guided by means of the limiting struts. In one embodiment, the limiting struts can each have an elongated hole along their extent.A round rod can be pushed through two oppositely spaced slots. This rod rests on the source material when the source material is present and weighs it down. The weight of the round rod is such that the source material can be removed from the material receiving device by the device, but is not accidentally stirred up by air currents. The air currents can be...

[0030] Fans are created in a production hall.

[0031] The column section is advantageously designed to be movable and has casters for this purpose. Thanks to the casters, the machine frame can be moved flexibly on a surface and used, for example, in variable production processes at different locations. The casters are preferably lockable to prevent the machine frame from rolling away during operation. The column section of the machine frame can be designed as a metallic strut and / or tubular construction.

[0032] One aspect of the invention is a machine frame for a device for providing packaging cushioning material, comprising a stand section for positioning the machine frame on a base and a receiving section for receiving and holding the device on the machine frame, characterized in that the machine frame comprises an adapter part which, on the one hand, is or can be releasably connected to the device and, on the other hand, is releasably connectable to the receiving section, and in that the releasable connection between the adapter part and the receiving section comprises a snap-in connection.

[0035] A further developed aspect of the machine frame is characterized in that the adapter part is designed like a portal and comprises two horizontally opposite side walls and an upper wall connecting the side walls.

[0036] A further developed aspect of the machine frame is characterized in that at least one projection is formed on a free end of the adapter part in the region of the locking connection, in particular the side wall of the adapter part, which projection can engage in a positioning recess in the receiving section.

[0037] A further developed aspect of the machine frame is characterized in that the receiving section is arranged on the stand section so as to be pivotable about a horizontal pivot axis and can be locked in any desired pivot position, in particular by means of a locking member.

[0038] A further developed aspect of the machine frame is characterized in that the receiving section is displaceably held on the column section via at least one slotted guide. A further developed aspect of the machine frame is characterized in that the receiving section has two parallel and spaced-apart, in particular vertical, walls for mounting the receiving section on the column section, and a base wall connecting these two walls for receiving the adapter part.

[0039] A further developed aspect of the machine frame is characterized in that the receiving section is designed to be height-adjustable relative to the support surface on the column section, wherein the receiving section can preferably be mounted on the column section in positions at different distances from the support surface.

[0056] In the following, functionally equivalent elements and areas in different figures and in different

[0057] Embodiments have the same reference symbols. Therefore, they are usually only described in detail when first mentioned, and subsequent embodiments generally only describe differences from previous embodiments. Furthermore, for reasons of clarity, not all reference symbols may be included in all figures.

[0058] Fig. 1 shows a machine frame 10 according to the invention for a device 12 for treating and / or feeding a starting material in the course of providing packaging cushioning material in a first embodiment. The machine frame 10 comprises a stand section 14 for positioning the machine frame 10 on a base 16 and a receiving section 18 for receiving and holding the device 12 on the machine frame 10. The device 12 is detachably held on the receiving section 18 by means of an adapter part 20 to be described in more detail. The machine frame 10 and the device 12 thus form a common arrangement or a combination of machine frame 10 and device 12.

[0059] The device 12 for providing packaging cushioning material can, for example, be a cushioning conversion machine with which a flat, web-shaped starting material made of paper is converted into a three-dimensional packaging cushioning material by crumpling, compressing and / or embossing. However, it is also possible for it to be a cushioning conversion machine with which a flat, web-shaped and tubular starting material made of plastic is converted into a three-dimensional packaging cushioning material in the form of an air cushion by inflation. The starting material can, for example, be provided wound up on a roll. However, it is particularly preferred if the starting material is present in a stack of a zigzag-folded starting material.The device 12 may further comprise a separating device with which sections of packaging cushioning material with a desired discrete length can be produced. The separating device may be a cutting device or a tearing device. The latter preferably cooperates with a starting material having perforation lines.

[0060] In the first embodiment, the upright section 14 is embodied, by way of example, as a metallic strut and tube construction. The tubes have a rectangular hollow profile. As shown in Fig. 1, the upright section 14 comprises two upright sides 22 spaced horizontally apart from one another. The two upright sides 22 of the upright section 14 are symmetrical to one another and connected to one another via a cross brace 24.

[0061] In the present case, each of the stand sides 22 comprises a horizontal tube part 26, two bent tube parts 28 which enclose an angle in particular between 90° and 100°, and an insert part 30.

[0062] Two casters 32 are mounted on each horizontal tube section 26, making the stand section 14 movable. At least two of the four casters 32 are lockable.

[0063] The horizontal pipe parts 26 preferably have four spaced-apart through holes 34 for fastening one of the bent pipe parts 28 to the horizontal pipe part 26. The plurality of through holes 34 on the horizontal pipe part 26 enables the bent pipe part 28 to be fastened in different positions on the horizontal pipe part 26. For fastening the bent pipe part 28 to the horizontal pipe part 26, two threaded bolts 36 (see, for example, Fig. 6) are provided.

[0064] One end 38 of the bent pipe part 28 fastened to the horizontal pipe part 26 points away from the support surface 16. One of the insert parts 30 is inserted into this end 38 and fastened, for example, via two further threaded bolts 36, such that at least a part, preferably at least half of the insert part 30 protrudes from the bent pipe part 28, which is inserted into one end 38 of the second bent pipe part 28 and is connected to it, for example, via two further threaded bolts 36. The bent pipe parts 28 of a stand side 22 can be oriented relative to one another such that they have a substantially S-shaped (see Fig. 1) or C-shaped (see Fig. 10, fourth embodiment of the machine frame) profile in a side view.

[0065] In the embodiments shown, the post section 14 is adjustable in length. The bent tubular parts 28 interact with the insertion element 30 as telescopic hollow profiles (see Fig. 1). For this purpose, the insertion element 30 has a plurality of through holes 34 (not shown) so that the bent tubular parts 28 can be attached to it at different distances from one another.

[0066] The receiving section 18 is pivotably arranged about a horizontal pivot axis 42 on free end pieces 40 of the second bent tubular parts 28, which point away from the support surface 16. The horizontal pivot axis 42 runs between the two upright sides 22. Fig. 2 shows an enlarged partial view of the receiving section 18 from Fig. 1.

[0067] The receiving section 18 has two parallel and spaced-apart, and here exemplary vertical walls 44 for mounting the receiving section 18 to the post section 14. The two vertical walls 44 are here exemplary connected to one another at one end by means of a base wall 46 for receiving the adapter part 20. The vertical walls 44 and the base wall 46 are exemplary screwed to one another in the present case. However, it is also possible for the receiving section to be made from one part or for the vertical walls and the base wall to be connected to one another by means of a welded connection (not shown here).

[0068] The receiving section 18 is connected to the stand section 14 by means of two threaded bolts 36. In the embodiment shown in Fig. 2, an angle connector 48 is arranged on the free end pieces 40 of the second bent tube parts 28 for the connection to the receiving section 18 on a side facing the placement surface 16 and on a side facing away from the placement surface 16. The angle connectors 48 form, with a lateral side 50 of the second bent tube parts 28, a surface that is vertical to the placement surface 16. A threaded bolt 36 in each case extends through a through-hole 34 in one of the walls 44 and pivotably connects the receiving section 18 to the angle connector 48. The receiving section 18 and the stand section 14 are as shown in Fig. 2 is designed in this embodiment such that the free end pieces 40 of the second bent tube parts 28 are arranged between the walls 44 of the receiving section 18.The horizontal pivot axis 42 of the receiving section 18 is formed by the threaded bolt 36 which extends through the walls 44.

[0069] In addition, the receiving section 18 is held displaceably on the post section 14 via slotted guides 52. The slotted guides 52 enable the pivoting of the receiving section 18 to be guided. Furthermore, a pivoting movement 54 about the pivot axis 42 can be guided and limited by the slotted guides 52. The slotted guides 52 are formed in the two parallel walls 44. Each slotted guide 52 here comprises at least one arcuate slot 56. An apex 58 of the arcuate slot 56 lies above the pivot axis 42. A locking member 60 extends through the arcuate slot 56 into the angle connector 48, to which the receiving section 18 is not connected via the threaded bolt 36. The locking member 60 and the arcuate slot 56 form the slotted guide 52. The locking member 60 is in this case a clamping lever.The receiving section 18 can be locked in any pivoting position using the locking device 60.

[0070] The receiving section 18 is designed to be height-adjustable relative to the support surface 16 on the stand section 14. In the embodiment shown in Fig. 2, the receiving section 18 can be mounted on the stand section 14 at different distances from the support surface 16. For this purpose, the angle connectors 48 have, for example, two through-holes 34. In addition, a plurality of arcuate slots 56 and through-holes 34 are provided on the walls 44, which are arranged at a distance from one another perpendicular to the base wall 46.

[0071] The receiving section 18 can be attached to the stand section 14 in two orientations (compare Fig. 2 with Fig. 9). In the first orientation, the base wall 46 is located at the top with respect to the walls 44 (see Fig. 9) and in the second orientation, it is located at the bottom (see Fig. 2). Thus, in the first orientation, the receiving section 18 is open downwards (Fig. 9) and in the second orientation, it is open upwards (Fig. 2).

[0072] The machine frame 10 thus comprises several options for adjusting the height position of the receiving section 18, more precisely the base wall 46 of the receiving section 18, relative to the support surface 16. The height position can be influenced via the length-adjustable column section 14, by mounting the receiving section 18 in different positions spaced from the support surface 16 on the column section 14, and / or by the two orientations of the receiving section 18 on the column section 14.

[0073] As shown in Fig. 8, the receiving section 18 can be fastened to the upright section 14 via coupling parts 61. For this purpose, a coupling part 61 is arranged between the upright section 14 and the receiving section 18 for each fastening in order to bridge the distance in the horizontal direction. The receiving section 18 can thus be adapted to different widths of upright sections 14. The angle connectors 48 are arranged accordingly on the coupling parts 61 for connection to the receiving section 18. In contrast to the embodiment shown in Fig. 2, the receiving section 18 is inserted between the upright section 14 and then pivotably connected to the angle connectors 48.

[0074] Fig. 2 shows that the adapter part 20 is detachably connected to one side of the base wall 46, so that it is arranged between the walls 44. It is also conceivable that the adapter part 20 is connected to the other side of the base wall 46 (see, for example, Fig. 9).

[0075] The detachable connection between the adapter part 20 and the receiving section 18 comprises a snap-in connection 62.

[0076] Fig. 3 shows an enlarged view of the adapter part 20. The adapter part 20 is designed like a portal and comprises two horizontally opposite side walls 64 and an upper wall 66 connecting the side walls 64.

[0077] The locking connection 62 is formed on one side wall 64. On the other side wall 64, an engagement region 68 is formed for positively hooking the adapter part 20 onto the receiving section 18 and thus for positioning the adapter part 20 on the receiving section 18. Through the interaction of the engagement region 68 and the locking connection 62, the adapter part 20 and thus the device 12 can be releasably fastened to the receiving section 18, as will be shown below using the exemplary embodiments.

[0078] The engagement region 68 of the adapter part 20 in the present case comprises an angle piece 70 which is formed integrally with the side wall 64 of the adapter part 20 ( FIG. 3 ), which angle piece can be produced, for example, by forming. The angle piece 70 projects from the side wall 64 in a direction away from the other side wall 64. The receiving section 18 has a recess 72 on the base wall 46 for the positive hooking of the engagement region 68 of the adapter part 20 (see FIG. 5 ). By hooking in the engagement region 68, the adapter part 20 is pre-positioned on the receiving section 18. The engagement region 68 of the adapter part 20 functions as a pivot bearing 74 with play. When the adapter part 20 is hooked onto the base wall 46 of the receiving section 18, it can be pivoted in a direction 76 toward the base wall 46. The pivoting movement of the adapter part 20 in the direction 76 allows it to be locked to the receiving section 18.The locking connection 62 is formed by the interaction of a rear-engaging region 78 and a pre-tensioned rear-engaging region 80. In the embodiments shown in the figures, the rear-engaging region 78 is formed as two openings 82 on the side wall 64 of the adapter part 20 (see Fig. 3). The rear-engaging region 80, which can be brought into engagement with the openings 82 of the adapter part 20 for the locking connection 62, is formed by spring-tensioned locking elements 84. The locking elements 84 are arranged such that they can engage in the openings 82 of the adapter part 20 when the adapter part 20 is pivoted down in the direction 76. Fig. 5a shows the spring-tensioned locking element 84 in a detailed view. The spring-biased locking element 84 is designed here, for example, to be movable parallel to the base wall 46 of the receiving section 18.

[0079] Furthermore, the adapter part 20 has, at a free end 85 in the region of the locking connection 62, four projections 86 extending from the side wall 64 of the adapter part 20, which projections can engage in positioning recesses 88 in the receiving section 18 (see Fig. 3 or Fig. 4). The projections 86 additionally enable the adapter part 20 to be positioned as intended relative to the spring-loaded locking elements 84.

[0080] As can be seen in Fig. 4 and Fig. 5, the adapter part 20 can be pivoted after hooking in the direction 76 onto the spring-loaded locking elements 84. In doing so, the projections 86 engage with the positioning recesses 88. Subsequently or simultaneously, the locking elements 84 are displaced from their initial position by the adapter part 20 against the spring preload until the locking elements 84 are aligned with the openings 82, engage in them and thus the locking connection 62 between the

[0081] adapter part 20 and the receiving section 18.

[0082] The spring-biased locking elements 84 can be moved against the preload by means of manually operable operating elements 89 (see Fig. 5a) arranged on the receiving section 18, which are designed as push buttons 90. It is conceivable that the push buttons 90 act on the locking element 84 by means of wedge-shaped inner surfaces (not shown). As a result, the locking elements 84 can be manually disengaged from the openings 82 again after the adapter part 20 has been locked to the receiving section 18, so that the adapter part 20 and thus the device 12 can be released from the receiving section 18.

[0083] The machine frame 10 also includes a material receiving device 92 for a starting material to be treated (not shown), for example, for a flat material made of paper, cardboard, or plastic. The starting material is designed as a continuous material. The material receiving device 92 is designed to receive the starting material directly, in or on a transport means in the material receiving device 92.

[0084] In the embodiment shown in Fig. 6, the material receiving device 92 comprises a support surface 94. The support surface 94 is arranged with the machine frame 10 in the respective connection area between the bent pipe parts 28 and the horizontal pipe parts 26 and extends between the stand sides 22. The support surface 94 has a gradient in the direction of the bent pipe parts 28. In addition, the material receiving device 92 shown in Fig. 6 and Fig. 7 comprises two limiting struts 96 which extend from the support surface 94 along the stand section 14 in the direction of the receiving section 18 and are horizontally spaced from one another. The limiting struts 96 serve to laterally limit the starting material. In the present case, the limiting struts 96 are formed from two limiting surfaces 98 which are in particular identical and at an angle to one another. The boundary surfaces 98 preferably enclose a right angle.In each boundary surface 98, an elongated hole 100 is provided, which runs along the longitudinal extent of the boundary surface 98 and opens in an arcuate manner into a returning end 102 on a side facing the receiving section 18. A round rod (not shown here) can be guided through two opposite elongated holes 100 and rests on the starting material in order to secure it in the material receiving device 92. To fill the starting material, the round rod can be positioned in the returning end 102 of the elongated hole 100. Both boundary struts 96 are identical parts here.

[0085] A horizontal distance between the limiting struts 96 is adaptable to a width of the starting material or its means of transport. For this purpose, the limiting struts 96 can be mounted at different positions in the horizontal direction on the cross strut 24 of the stand section 14 (see Fig. 7). For mounting the limiting struts 96, the cross strut 24 has through holes 34 spaced at different distances from one another. Furthermore, the end of the limiting struts 96 facing away from the receiving section 18 is provided with engagement projections 104 which are in the

[0086] The support surface 94 has engagement holes 106 spaced at different distances. The engagement holes 106 of the support surface 94 and the through holes 34 of the cross strut 22 are predetermined such that the distance between the limiting struts 96 can be adjusted to 200 mm, 300 mm, 400 mm and 600 mm.

[0087] As an alternative to the material receiving device 92 shown in Fig. 6 and Fig. 7, as indicated in Fig. 10, the machine frame 10 can have a recessed area 108 between the two upright sides 22 for inserting the transport means, or the machine frame 10 can be easily pushed over the transport means, e.g. a pallet. To accommodate larger pallets, the overall width of the upright section 14 can be easily adjusted in the horizontal direction by means of cross braces 24 of the required length. For the pivotable connection of the receiving section 18 to the upright section 14 which is wider in the horizontal direction, the receiving section 18 can be adapted to the overall width of the upright section 14 by means of the aforementioned coupling parts 61.
