Description

TRANSPORTATION SYSTEM TO TRANSPORT PRODUCTS, AND SLIDING DEVICE The invention relates to a transport system, comprising a mat or endless conveyor belt that extends between two wheels of deviations, to transport products between the wheels of deviations in a direction of transportation, in which the transportation system also comprises a sliding or sliding device for transferring, adjacent to a diverting wheel of or to a conveying surface of the conveyor mat or mesh, the products conveyed by the conveyor mat or mesh to or from said diverting wheels, in the wherein the sliding or sliding device comprises a number of separately interchangeable projections or extensions that extend on the transportation surface, the transportation surface is substantially planar and has a number of linear or straight slots extending in a transportation direction, and each of the projections or extensions of the sliding device or co Sliding cooperates with a slot. REF .: 29355 The invention also relates to a sliding or sliding or sliding device for transfer, adjacent to a diverting wheel from or to a conveying surface of a conveyor mat or mesh, products that are transported by the mat or mesh of the conveyor in a conveying direction to or from the diverting wheel, wherein the sliding or sliding device comprises a number of outwardly extending, separately interchangeable and substantially parallel projections or extensions to cooperate with a surface of transportation. Such transportation systems and sliding or sliding devices are known and are used for the transportation of all kinds of products in a large number of different environments. A particularity that requires the application of such a transport system and such a sliding or sliding device refers to the transport and transfer of product through a pasteurizer to pasteurize the products. During the pasteurization, the products, in particular, beverages, after they have been introduced in a container, are heated for some time, so that the stored life of the products is prolonged. At the end, the sealed containers containing the product are placed in a channel or conveyor track and passed through a box or box forming a long, impermeable tunnel. The channel or track of transport, frequently has a length of 25-35 and an amplitude of 3-5 m. The track or transport channel passes the products inside the tunnel along a number of zones, where the hot water that has a different temperature zone, is sprayed on the containers, for example 20-40-60-80- 60-40 ° C. Such tracks or transport channels transport the products at a speed of approximately 0.5-1 m / sec and have a capacity of approximately 30-70,000 containers per hour. In the zones of temperature, approximately 25 m3 of water per hour are sprayed on the products per m2 of surface area of the track or canal. In order to use the water more efficiently, the transport track or channel is preferably of a double-deck design. The containers transported through the pasteurizer by means of the transport track or channel are usually containers or bottles made of metal, plastic or glass. For reasons of cost, efforts have been made to design the transportation track or channel as a mat or conveyor belt without a circulatory end in a transportation direction between a first diverting wheel and a second diverting wheel. Such a mat or conveyor mesh is known from European Patent EP 0 339 309. The conveyor mat or mesh is constructed of a large number of interconnected plastic modules, each constructed of a number of fins extending in parallel, face to face with respect to a transportation direction. A number of these fins are provided with a raised rib. The upper sides of these ribs together constitute a transportation surface. Adjacent to the diverting wheels, the products are transferred to or from the transport surface by a sliding or sliding device comprising a comb having a smooth part that carries projections in the form of teeth. The teeth project between the raised ribs so that during unloading, the front products are transferred from the transport surface and pushed into the flat part of the comb through the teeth by the following products, while, through the second Bypass wheel, the modules continue their endless form. During the supply of products, the front products are pushed, to the site of the first detour wheel, from the flat part of the comb on the transport surface by means of the teeth for the following products. A disadvantage that exists of the known transportation system and the sliding or sliding devices, is that they are not suitable for the transportation of glass containers through a pasteurizer. When it is during pasteurization, the pressure in the package increases. This can lead to a breakage of about 1% of the glass containers as a consequence of the weak stain on the glass and / or an excessively high degree of filling of the container. In the mat or mesh of the known conveyor and in the known transportation system, the glass fragments of the broken containers are stuck between the fins and / or ribs of the modules. In addition, sliding or sliding devices are damaged. In particular, the teeth of the comb are broken or twisted by the fragments of glass introduced between the ribs and / or the fins, as a result of which an obstacle is formed for the containers. In addition, the glass fragments may accumulate under the portion flat of the comb of the sliding or sliding device, causing the comb to rise or rise in the plane of transportation and the teeth forming an obstacle to the products. In practice, in a pasteurizer for products packaged in glass containers, such transportation systems and sliding or sliding devices are used only as tracks or transportation channels. It is also the case when such plastic transportation systems and sliding or sliding plastic devices are used in other circumstances where high requirements are placed on temperature resistance, wear resistance and firmness. Document DE 20 38 966 shows a sliding or sliding device in the form of a plate of projections or extensions, the projections or extensions of which are each designed to cooperate with a longitudinal groove in the conveying surface of a conveyor, such as a belt. conveyor. The plate of projections or extensions comprises a rotating support beam in which the projections or extensions are each separately interchangeable connected by means of a screw. A disadvantage of this plate of projections or extensions is that the projections or extensions are not directly accessible to be exchanged, but must first be turned upwards next to the support beam. In particular, for applications where the projections or extensions are not easily accessible and / or the sliding or sliding device comprises relatively a large number of projections or extensions, as in a sliding or sliding device incorporated in a pasteurizer, the exchange and replacement cause problems . The object of the invention is to provide a temperature-resistant transportation system, resistant to wear and tear and a sliding or sliding device resistant to temperature, resistant to wear and firmness of the type mentioned in the opening paragraph, in particular suitable for the transport of glass containers through a pasteurizer, in which the transportation system and the sliding or sliding device do not have the disadvantages mentioned above . At this point, the transportation system according to the invention is characterized in that the projections or extensions are each connected to the sliding or sliding device so that they are exchanged substantially in a vertical direction. In addition, it is interpreted that if a projection or extension breaks or bends, it can be quickly removed as a separate unit and is directly accessible for replacement, while the other projections or extensions can remain in position. By connecting the projections or extensions to the sliding or sliding device and / or to each other by means of an instantaneous connection, the removal and replacement can also be facilitated. It is noted that "the projections or extensions" are understood to suggest the part cooperating with the slot and that the projections or extensions may therefore be constructed of several parts. In another embodiment, the transportation system according to the invention is characterized in that each of the projections or extensions comprises a substantially flat support body that carries a projection or extension adjacent to one end thereof and that transports the members. adjacent rapidly to the opposite side thereof, wherein the support body constitutes separate, spaced apart surfaces transversely to the conveying direction in interspaced openings. As a result, at the site of the detour wheel, the slot can be protected against the introduction of fragments, while the fragments can be discharged between the separation surfaces. Should the open spaces between the support bodies be obstructed, this is directly noticeable to an observer, so that the open spaces can be cleaned in time and in a simple manner.

The sliding or sliding device according to the invention is characterized in that each of the projections or extensions are connected to the sliding or sliding device to be exchanged substantially in the vertical direction. In another embodiment, the sliding or sliding device according to the invention is characterized in that the projections or extensions are each separately interchangeably connected to the sliding or sliding device and / or to each other by means of an instantaneous connection. By connecting the clamping members to each other so that they are separately interchangeable, the rings can be connected to form a bundle of fins which can be economically connected to a structure. In yet another embodiment, the sliding or sliding device according to the invention is characterized in that the support bodies are slidably connected to a structure, so that they can run relatively to the structure substantially transverse to the plane in which they are placed. they find each other. It is further provided that during the expansion of the conveyor mat or mesh, the projections or extensions may be slidable transversely to the direction of transportation. However, they can be taken through the slides, and move the conveyor mat or mesh, transverse to the transportation direction. The additional features and advantageous constructions of the transportation system are given in the subclaims and will be discussed here below based on a number of embodiments of the invention shown in a scheme.

The figures are schematic representations of preferred embodiments of the invention and serve only as illustrations. In the figures, the identical or corresponding parts are designated by identical reference numbers. With reference to Figures 1 and 2, a detail of the transportation system 1, according to the invention is shown here- The transportation system 1, comprises a mat or mesh of the endless conveyor 2 traveling around the diverting wheels. In Figures 1 and 2, only a part of the mat or mesh of the conveyor 2 is visible, adjacent to the "end" of the mat or mesh of the conveyor 2 at the place where the mat or mesh the conveyor 2 travels around the deflection wheel 5. The mat or mesh of the conveyor 2 comprises a number of rows of plastic modules 4, following each other in the direction of transportation 3 and extending transversely to the transportation direction. In Figure 1, in each row, only one module 4 is shown. In the transportation direction, each of the modules 4 has a front side 6 and a rear side 7. On the front and rear sides 6, 7, each one of the modules 4 are provided with articulation hinges 8. The articulation hinges 8 of the modules following one another in the transport direction 3, cooperate and are engaged by means of pins of the hinges 9 extending transversely to the transport direction 3. The pins of the hinges 9 extend to the transportation direction 3 through the width of the mat or mesh of the conveyor 4 and are preferably made of plastic. The upper surface 10 of the modules together constitute a transportation surface 11. Preferably, the mat or mesh of the conveyor 2 is constructed of rows of modules 4 whose side faces 12 end against each other, while the modules 4 of the rows that follow the others in the direction of transportation 3 wobble relative to each other, as in a pattern of stone bricks. The modules 4 are each provided through openings 13 extending substantially transverse to the transportation surface 11. It is noted that "the openings 13 extending substantially transverse to the transportation surface 11" should also be understood to include openings extending obliquely from the upper surface 10 to the lower surface 37 of the module 4. The modules 4 have a substantially flat upper surface 10 on which the slots 14 extending in the transport direction 3 are provided. The modules 4 are coupled in such a way that the transportation surface 11 is substantially planar and comprises a number of substantially linear or straight slots 15 which extend in the transport direction 3 over the length of the mat or mesh of the conveyor 2 and are constructed from slots 14. The transportation system 1 also co a sliding or sliding device 16 placed adjacent to the diverting wheel 5, to transfer, from the transportation surface 11, products which are transported by the mat or mesh of the conveyor 2 in the direction of transportation 3 to the wheels 5. The sliding device 16 comprises a number of substantially flat supporting bodies 17, each carrying a projection or extension 18 at one end thereof and comprising, at an opposite end, a cylindrical fastening member 19. By means of its fastening members 19, the support bodies 17 are each mounted separately in the fastener openings 21 in the assembled block 20 in such a way that their respective projections or extensions 18 cooperate each with one of the grooves 15, while between the bodies of support 17, an interspace or intersector is presented 28. The operation of the transportation system is as follows. The products placed on the transport surface 11 of the mat or mesh of the conveyor 2 are moved in the direction of transportation 3 by the driving of the deflection wheels in the direction of the arrows 22. As a result, the projections 23 , 24, provided on the outer circumference 25 of the diverting wheel 5 engage the modules 4 in the chambers 26. At the site of the diverting wheels 5, the modules 4 of the conveyor 2 mat or mesh first follow the circumference outer 25 of the diverting wheel 5 for approximately 180 ° and subsequently follow the return sides of its endless shape. In the diverting wheel 5, the products are transferred away from the transportation surface 11, through the sliding or sliding device 16. If necessary, at the location of the diverting wheel 5, the projections or extensions 18 of the sliding or sliding device 16 project into the slots 15, preferably to a position above or below the center line of the diverting wheel 5, causing the products carried in the transportation direction 3 to be transferred from the transportation surface 11 by the following products, and thereby be pushed, through the projections or extensions 18, into the upper surface 27 of the support bodies 17 in the direction of the assembled block 20. Next, the products are furthermore discharged in a generally known manner.

The products can be placed on the transportation surface 11 by means of a sliding or sliding device 17 placed adjacent to the first turning wheel, in which the projections or extensions 18 of the sliding or sliding device project in a direction of transportation 3 in the slots 15 (not shown). At the end, the products are transferred, by the products that follow in the direction of transportation, on the upper faces 27 of the support bodies 17 and through the projections or extensions 18, to the transportation surface 11, while the dirt, etc., falls into the spaces between the support bodies 17. When the products are glass bottles and when the system 1 is used as a channel or transport track in a pasteurizer as described here above, a number of bottles will be broken during the transport and due to the shape of modules 2, fragments of glass and large pieces of dirt will accumulate on the belt or conveyor belt. Through the openings 13 of the modules 4, the available water, small parts of dirt and glass sand can be discharged from the transportation surface 11 through the modules 4 during transport. The glass fragments and the large parts of dirt are removed or removed from the transport surface by the protrusions or extensions 18 and fall to the ground via the spaces 28 between the support bodies 17. The open spaces 28 between the support bodies must 17, obstructed, this is directly noticeable to an observer, so that the open spaces can be cleaned in time. When a projection or extension 18 or a support body 17 is damaged or bent, for example due to glass fragments stuck on the transport surface, it is also directly perceptible. A support body 17 whose projection or extension 18 is damaged or which itself was damaged may simply be replaced as a unit lost by removal or removal of the support body 17 from the assembled block 20 substantially in a vertical direction and by subsequently mounting a new projection or extension substantially in a vertical direction, in a manner which will be explained in more detail in the discussion of the assembled block 20. With reference to Figures 3 to 9, the different parts will be discussed in more detail. of the transportation system and the sliding or sliding device. It is noted that exemplary embodiments merely discussed refer to preferred embodiments and that within the structure of the claims, many other large modalities are possible. With reference to Figures 3 and 4, a module 4 is shown here. The upper surface 10 of the module 4 is substantially flat, allowing the products to remain stably in the portions of the upper surface which is located between the slots. 4. Each of the slots 4 has two side walls 29, 30, which are connected through a base 31, so that the opportunity for fragments is reduced through the module 4. Transversely to the direction of transportation, the grooves 4 have a trapezoidal section, which facilitates cooperation with a projection or extension 18. The base 31 of the grooves 14 is curved with a radius 32 such that when the mat or mesh of the conveyor 2 travels around a detour wheel 5. , the slot 15 in the site forms a circular arc with the axes of the diverting wheels 5 as the center. (Figure 2). This prevents the flow of water in the longitudinal direction of the slot 15 and prevents the projections or extensions 18 from moving up and down relative to the transportation surface 11 as a consequence of the conveyor mat or mesh deformed as a polygon in the site of the diverting wheel 5, and / or prevents the formation of an opening and lock gap between the projections or extensions 18 and the groove 15. The section of the grooves 4 transverse to the conveying direction 3 adjacent to the front surface 6 and the rear surface 7 of module 4, is larger than the one adjacent to the center 33 of the module 4, to facilitate the insertion of the projections or extensions 18 into the slots 14. Through the openings 13 they are designed as holes around, providing both on the upper surface 10 of the module 4 and in the base 31 of the grooves 14 provided in the upper surface 10. In a direction parallel to the transportation surface, through the openings 13, there is a larger dimension of less than 15 mm, preferably less than 10 mm, in particular less than 7 mm. It is further provided that the opportunity for glass fragments to stick in the openings is reduced. The module 4 has its front surface 6 and its rear surface 7 provided with an equal number of articulation hinges 8. In a direction transverse to the transportation direction 3, the transport hinges 8 are spaced apart at a distance which is substantially equal to the amplitude of the articulation hinges 9, and on the front surface 6 and the rear surface 7 of the module 4 are wobbly relative to each other by the amplitude of an articulation hinge. Accordingly, particularly the shortening of the conveyor mat or mesh requires the minimum removal of only one row of modules 4. It is noted that the modules 4, whose hinge turns 8 are not wobbly relative to each other and / or which have a different number of hinge turns 8 on the front surface 6 and the rear surface 7, are also possible within the scope or structure of the claims. The articulation hinges 8 are each provided with a band 34 touching the upper face 10 of the module horizontally, with a radius of a constant magnitude, extending externally of the center line of the pins of the hinge 9, parallel to the direction of transportation 3, while the spaces between the articulation hinges 8 are provided with a recess 35 formed to correspond to the web 34. Furthermore, the mat or mesh of the conveyor 2 also has a flat transportation surface 11 at the site of the transitions between the webs. rows of the modules 4. However, during the folding of the mat or mesh of the conveyor 2, it is prevented that the glass sandstone is stuck on the upper face 10, in the spaces between the modules 4. The hinges of articulation 8 of the modules 4 each have a hinge gap 36 for accommodating a hinge pin 9. Giving hinge gap 36 can be realized in a simplified manner. e, an elongated design, the assembly and disassembly of the pins of the hinge 9, inter alia. The center lines of the hollows of the hinges 36 are located at least half the height of the module 4, that is, as close to the lower part 37 as to the upper face 10, to prevent the action of the sandstone. of glass from the bottom surface. With reference to Figure 5, a support body 17 is shown here, conveying a projection or extension 18. The support body 17 is preferably made of plastic. On the opposite side, the support body 17 comprises a fastening member 19. The support body comprises a curved side 43 which cooperates with the curvature of the groove 15 in the mat or mesh of the conveyor 2 at the location of the diverting wheel 5 (Figure 2). Preferably, the section of the projection or extension 18 and the curved side 43 are transverse to the transportation direction 3 designed to correspond to the groove 14, and is in particular trapezoidal, so that the projection or extension 18 and the curved side 43 protect at least the side walls of the grooves 15 against the introduction of glass. The support body 17 has a flat upper side 27 for transferring the products from the transportation surface 11 in the direction of the assembled block. The support body 17 also comprises an instantaneous connection, designed as a projection or instant extension 46 for cooperation with a corresponding recess 47 in the assembled block. The projection or extension 46 comprises a cover 48 which protects the projection or instantaneous extension 46 of fragments of glass and those that fall with it, and which acts as a coupled member to operate the projection or instantaneous extension 46. Placing a bar as a conductive screw, between the shelf 48 and the instantaneous ring, the shelf 46 can be coupled and be adapted to block the projection or instant extension 46 in a depressed condition. This facilitates the assembly / disassembly of the body of the support 17 in the assembled block 20. With reference to Figure 6, there is shown a mounted block 20, which has a number of parallel clamping openings 21 spaced apart in a transverse direction. mounted block 20, comprising an upper row of holes 49 whose diameter is measured lengthwise and widthwise in the longitudinal direction thereof, a recess 47 and a lower row of holes 50. In the case of a mat or wide conveyor mesh 2, a number of assembled blocks 20 are placed side by side, transverse to the transportation direction 3. The assembled block 20 is preferably made of plastic. During the assembly or assembly of a support body 17 in the assembled block 20, the projection or instantaneous extension 46 of the support body 17 is first fixed in a folded position by passing a bar, such as a driver screw, between the projection or extension instantaneous 46 and cover 48. Next, the fastening member 19 is passed substantially vertically through one of the holes in the upper part of the row of the holes 50. Upon removal of the conductive screw, the projection or extension instantaneous 46 bounces to secure the fastening member 19 through cooperation with the recess 47. By passing the bar in the sliding or sliding device from above and placing it between the projection or instant extension 46 and the shelf 48, the instantaneous connection it can be opened and the body of the support 17 can be removed or removed together with the bar in the vertical direction. In the figures, the vertical direction is indicated by an arrow P. In particular, when the sliding or sliding device is used within a box, such as in a pasteurizer, the removal or removal and replacement of the projections or extensions may be it is substantially simplified. It is also possible to provide the projection or instant extension 46 at an oblique angle with which, during insertion, the projection or instant extension is folded through contact with an edge of the assembled block 20. In this case, the use of a bar during assembly or assembly it is not necessary. After assembling or mounting the support bodies 17 in the block 20, the projections or extensions 18 are each separately interchangeably connected to the sliding sliding device 16 and the support bodies 17 extend substantially parallel with interspaces or mutual intersections 28, and each one has its protrusions or extensions 28 projecting from the sliding or sliding device 16 into a slot 15, against the conveying direction 3. By giving the upper part 44 of the holding member 19 uh larger diameter than the lower part 45, it is provided that the The upper part of the fastening member 19 contains sufficient material for raising and forcing in the transport direction 3. By designing the upper rows of the holes 49 so that in a mounting or mounting direction, there is a decrease, preferably by measuring the diameter of the material in the transverse direction of the assembled block 20 between the holes 49, 50 however , has sufficient force to allow shortening of the assembled block 20 in a transverse direction between the holes 49, 50 In this case, the next material to a hole 49 adjacent to the edge is firm enough to support the support body 17 without bending down, which is not the case if the diameter is larger along the length of the holes 49. The block assembled 20 is further provided with two opposite grooves 51, 52, which extend transversely in the conveying direction 3, thereby the mounting block or assembled 20 can be mounted on a structure 53. Due to the temperature in the pasteurizer, the mat or conveyor 2 mesh will expand, for example by 10 mm per diameter at an elevation temperature of 60 ° C. The slots 51, 52 have the advantage that upon the expansion of the mat or mesh of the conveyor 2, the assembled block 20 can run or slide transversely to the direction of the conveyor. The slots 51, 52 also allow the expansion of the assembled block 20 relative to the structure 53, due to heating, without twisting of the assembled block 20. Furthermore, through the use of the slots 51, 52, the mat or mesh is moved of the conveyor 2 transverse to the conveying direction 3 which can also be taken due to the small differences in the amplitude of the articulation hinges 8 and the spaces between the articulation hinges of the hinges of a module 4. With reference to the Figure 7, a drawing of the schematic perspective of another embodiment of the sliding or sliding device 16 shows therein, a condition partially disassembled or disassembled. In this embodiment, also the support bodies 17 are each located substantially in a plane and provided with a projection or extension 18, a linear or straight edge 27 and a curved edge 43. However, the support bodies 17 have their surfaces laterals 54 provided with a fastening member 55. By means of the fastening members 55, the supporting bodies 17 can each be separately interchangeable interconnected, while in each case a fastening member 55 cooperates with a lateral surface (not visible in Figure 7). ) of a following support body 17. In Figure 7, the support bodies 17 are interconnected with interspaces or mutual intersections 28 by means of the fastening members 55, transversely in the conveying direction 3, to form a finned package 60. This packet 60 can be directly connected to the structure 53 in an economical manner. Depending on the width of the conveyor mat 11, a number of these packages 60 are placed face to face at the site of a diverting wheel 5, transversely to the conveying direction 3, so that the protrusions or extensions 18 the support bodies 17 each cooperate with a groove 15 in the transportation surface 11. In this example, the support bodies 17 are each provided with opposite grooves 56, 57 cooperating with a lower guide 58 and a guide upper 59. The guides 58, 59 are each mounted on the structure 53. This allows the flap pack 60 to run transversely in the transportation direction 3 to compensate for expansion of the conveyor 2 mat or mesh transverse to the direction of travel. transportation 3 and / or moving from the mat or mesh of the conveyor 2 transverse to the conveying direction 3. When a projection or extension 18 or a support body 18 is damaged. The upper guide is exchanged first of the structure 53. After exchanging the pack of fins 60 of the lower guide 58, the damaged support body 17 is removed from the package by removal or removal of the fastening member 55 from the lateral surface of the body. of support 17 joining and / or removing the supporting body of the fastening member 55, the projections or extensions 18 are each separately interchangeably interconnected. After replacing the body of the support 17, the assembly can take place in the reverse order. If desired, the rigidity of the package 60 transverse to the conveying direction 3 can be increased by placing a linear or straight tension bar 61 through the pack of fins 60 via the holes 62 in the support bodies 17, and to twist the bar with screws or arrows 63. The operation of the sliding or sliding device shown in Figure 7 is also identical to that sliding or sliding device described above. It is noted that it is also possible to connect the support bodies to each other and / or the sliding or sliding device as well as to interchange directly, for example, through the use of a simple U-shaped guide. With reference to Figure 8 is shown in a bottom view, a schematic perspective drawing of yet another embodiment of the sliding or sliding device 16 according to the invention, wherein the projections or extensions 18 are each separately removably mounted on a guide plate 65; by means of two opposite wedge-shaped fastening members 64. Adjacent to the diverting wheel 5, the guide plate 65 is connected to a structure 53, so that the projections or extensions 18 each cooperate with a groove 15 in the transportation surface 11. In this mode, the products are pushed, by the following products, from the transportation surface 11 to the guide plate 65 via the projections or extensions 18 and subsequently subsequently downloaded. To decrease the damage to the projections or extensions 18, the projections or extensions 18 are elastically retained with guides 66 by means of springs 70. An object subjected to the transportation surface in a slot 15 and touching the projections or extensions 18 frontally, pushes the projections or extensions 18 in the guide 66, against the action of the spring 70. After the object has passed the projection or extension 18, the projection or extension 18 bounces. When a projection or extension 18 is damaged or a guide is damaged, the projection or extension 18, after the guide plate 65 which has been exchanged from the structure 53, can be separately interchangeable from the guide plate 65 by the pressure at the opposite clamping member 64 towards each other so that the projections or extensions of the guide 66 can be taken. The joint takes place by the pressure of the projections or extensions 18 in the guide 66. Figure 9 is a lateral elevation schematic of a detail of yet another embodiment of the sliding or sliding device 16 according to the invention. Here, the projections or extensions 18 are provided with elongated eyes 67 as fastening members 67. The projections or extensions 18 are curved and cooperate with the groove 15 at the site of the curvature around the diverting wheel 5. Analogously with the exemplary embodiment of Figure 8, the projections or extensions 18 are carried by the springs 71. The projections or extensions 18 are guided along the projections of the support 68. The sliding or sliding device 16 further comprises a guide plate, not shown in FIG. Figure 9, in which the products are transferred from the transportation surface 11 via the projections or extensions 18. The projections or extensions 18 can be exchanged as a loss unit after the union of the springs 71 and the pivot 69 It is noted that the application of the sliding or sliding device discussed above is not limited to the transportation system described in this example and that is Many variations of the transportation system and the sliding or sliding device, in particular of the instantaneous connection, are possible within the scope of the following claims.
