Description

Technical Field

[0001] The utility model relates to a conveying device and a box-type conveying unit. Background Art

[0002] Conveyor devices of the same type are used, for example, in the form of conveyor belts in the production of foodstuffs.

[0003] In modern food production, long block products, such as sausages or cheese, are sliced, portioned, checked, tested and packaged. Therefore, various inspection and testing steps are usually carried out before, during or after slicing, for example for quality assurance, weight checks and foreign body inspections using scales and X-rays.

[0004] The food blocks can be present in different sizes. In order to achieve high productivity, the bulky blocks are processed individually, while the narrower blocks are processed simultaneously (in parallel) in a multi-pass operation. Utility Model Content

[0005] It is therefore an object of the invention to provide a conveying device which can be adapted to changing requirements in a simple manner by varying the lane width and / or the number of lanes.

[0006] According to the invention, this object is achieved by a conveying device as follows and a cassette conveying unit as follows.

[0007] The present application discloses a conveying device for conveying products in a longitudinal direction corresponding to a conveying direction, having a width extending in a second transverse direction orthogonal to a first direction and a height direction orthogonal to the two directions, wherein the conveying device comprises a frame, the frame having a side portion oriented in a longitudinal direction and at least two transverse portions extending in a transverse direction, so that the width of the frame is determined by the length of the transverse portions. A driving roller is fixedly and rotatably arranged at or within the frame, the axis of which extends in a transverse direction and the length of which extends through the entire width of the frame, so as to directly act on at least one circulating conveying mechanism for driving. At least one cassette conveying unit is removably inserted into the frame, wherein the at least one cassette conveying unit is arranged in a fixed position in the longitudinal and transverse directions. The at least one cassette conveying unit has at least one steering member, which extends in a transverse direction and steers the circulating conveying mechanism, and the at least one circulating conveying mechanism runs around the driving roller, the at least two transverse portions and the at least one cassette conveying unit. In addition, the conveying device can be a belt conveyor.

[0008] The present application also proposes a box-type conveying unit, which is used within the framework of the conveying device of the present utility model.

[0009] By providing at least one cassette-like transport unit that can be inserted into a frame or removed by an operator, the transport device can be easily adapted to changing products to be transported, in particular changing product sizes.

[0010] Since the drive roller is mounted on the frame, preferably in the frame, in a fixed and rotatable manner, with its axis extending in the transverse direction y and its length extending substantially over the entire width of the frame, the at least one endless conveyor can be driven directly by a single drive roller, i.e. it can be driven. Unlike the drive shaft, the drive roller is directly engaged with the endless conveyor. If the endless conveyor is designed, for example, as an endless belt, at least a part of the outer surface of the roller or the roller shell directly rests against the inner surface or the inner side of the belt.

[0011] Obviously, the endless conveying means (respectively) forming the solid conveying track can be constructed in any manner known per se, depending on the intended application, such as, for example, strips, belts, belts, a plurality of individual belts, chains, leaf chains.

[0012] Since at least one deflection element, preferably in the form of a roller, a deflection roller, a deflection edge, etc., which deflects the circulating conveyor mechanism, is formed in this or these cassette conveyor units, the conveying device can be adjusted in a simple manner as required in terms of track width and number of tracks by removing this or these cassette conveyor units (after removing the respective circulating conveyor mechanism), by installing another cassette conveyor unit and / or changing the number of cassette conveyor units.

[0013] In addition, by arranging the cassette conveying unit that can be taken out by the operator, the cleaning that is mostly carried out periodically according to regulations that is especially needed in the food field of the whole conveying device is simplified. In addition, compared with the conveying device without the cassette conveying unit of the utility model, it is easier to replace individual components by taking out and replacing the cassette conveying unit in the event of a fault.

[0014] In the case of a plurality of cassette conveyor units installed, each individual cassette conveyor unit can be removed from the frame or inserted into it individually, i.e. independently of one another, for example downwards or preferably upwards in the height direction z, without having to remove other, in particular adjacent, cassette conveyor units for this purpose. "Removal upwards or downwards" also includes an inclined direction, provided that the movement has a component in the height direction z.

[0015] The at least one cassette conveyor unit is fixedly arranged on or in the frame in the longitudinal direction x and in the transverse direction y by means of corresponding stops. The degree of freedom of the at least one cassette conveyor unit in the height direction z is limited by the respective cyclic conveyor mechanism and is fixed in particular when the cyclic conveyor mechanism is in a tensioned state. Obviously, a stopper which limits the position downward (or upward) in the height direction z and a stopper in the form of a quick-engaging member (spring, hook, etc.) acting upward (or downward) in the height direction can be provided between the frame and the cassette conveyor unit.

[0016] The corresponding stops can, for example, be designed as engaging parts on the frame and the box conveying unit that are complementary in shape to each other, such as grooves, slots, recesses, U-shaped recesses, which are placed in engagement with corresponding counterparts, such as crossbeams, side parts, rails, pins, protrusions, when the box conveying unit is installed in the frame.

[0017] In a special design of the present invention, at least two of the transverse parts of the frame act as a stop for at least one installed box conveying unit in at least one direction x, z, y, wherein the at least one installed box conveying unit preferably also abuts against the transverse part along the height direction z or against the height direction z.

[0018] In a preferred embodiment of the invention, the conveying device has a tensioning device (acting in any radial direction), by means of which the at least one endless conveying mechanism is tensioned and can be removed from the frame and the at least one cassette conveying unit accommodated therein in the relaxed state in the transverse direction y. The relaxation advantageously facilitates the removal and installation of the endless conveying mechanism, since otherwise the endless conveying mechanism would have to be correspondingly extended or at least a part of the conveying device would have to be loaded and unloaded for this purpose.

[0019] In other embodiments of the invention, the at least one cassette conveyor unit has two side parts oriented in the longitudinal direction x, preferably on the outside, and at least one spacer for the side parts, preferably on the outside, which defines a spacing in the transverse direction y. Thus, for example, two separately constructed side parts can be connected by two spacers in the form of crossbeams or a spacer in the form of a base plate and / or a cover (perhaps with punched holes). It is obviously also conceivable that the side parts and the base plate or the cover are designed as a one-piece U-shaped profile, in particular in the form of a sheet metal bent part.

[0020] In other designs of the utility model, the at least one cassette conveying unit comprises a guide for the at least one circulating conveying mechanism. Preferably, the guide and / or the steering member are mounted or supported in a fixed position in the side portion of the cassette conveying unit. Preferably, the guide and / or the steering member can be removed by an operator, preferably in the height direction z, and / or are designed as rotatable rollers. Since the guide and / or the steering member can be easily removed, it is advantageous that other components of the conveying device can also be easily removed for replacement or for cleaning (also reinstalled).

[0021] In a particularly preferred embodiment of the invention, the at least one cassette conveyor unit is designed in at least two parts, with a carriage that can be moved (relative to the rest or the parts of the cassette conveyor unit) in the longitudinal direction x. The movable carriage in this case comprises a deflection element for tensioning and relaxing the at least one endless conveyor mechanism and thereby establishing or eliminating the engagement of the at least one endless conveyor mechanism with the drive roller. The tensioning and relaxing can be carried out by an actuator, in particular a pneumatic cylinder, which moves the movable carriage.

[0022] Preferably, such an actuator can be assigned to each cassette transport unit, wherein it is of course also conceivable to provide one actuator for a plurality of cassette transport units in the transport device.

[0023] In a further embodiment of the invention, at least one, preferably each, cassette transport unit has an actuator, so that the actuator is part of the cassette transport unit.

[0024] In a preferred design of the utility model, the frame remains in the machine when the cassette conveyor unit is replaced. The machine can be designed, for example, as an X-ray inspection device, a metal detector or a scale. The cassette conveyor unit can be designed at least partially as a weighing belt or contain such a weighing belt. Advantageously, the frame therefore also remains in the machine in an unchanged installed posture when the cassette conveyor unit is inserted and / or removed, so that after cleaning, maintenance, change of the number of lanes, etc., it is not necessary to re-perform the previously completed adjustment of the frame and thus the conveyor device.

[0025] In other designs of the present invention, a plurality of cassette conveying units can be installed in the frame, and they have the same or different widths. Thus, the adjustment possibilities (track width and / or track number) of the conveying device are improved.

[0026] The endless conveyor can respectively run around one or more cassette conveyor units and cover them in width, so that in this way a physical lane with a specified width is formed. This advantageously further increases the possibility of adjusting the number and / or width and / or position of the lanes to the respective requirements. Since the endless conveyor can also be designed in the form of a plurality of (narrow) individual strips, in particular belts, it is of course also possible for a plurality of narrow individual strips to run around the cassette conveyor units.

[0027] In a further embodiment of the invention, at least one cassette transport unit, preferably each cassette transport unit, comprises at least one weighing unit for determining the weight of the product transported by the transport device.

[0028] It is obviously also conceivable to form a virtual lane (for example, for jointly conveying an extra-wide product) by a single or multiple cassette conveyor units and the respective circulating conveyor mechanisms running therearound by correspondingly synchronizing the actuators.

[0029] As mentioned above, since the conveying device according to the utility model has a modular structure, the replacement of components and the adjustment according to new requirements (number of lanes, lane width) as well as the maintenance and cleaning of the conveying device become much easier by providing a box-type conveying unit that can be loaded and unloaded.

[0042] like Figure 1-4 The belt conveyor 1 shown comprises a frame 3 which is composed of two outer side parts 15, 17 and a transverse part 19, 21 connecting them. The length of the transverse part thus substantially determines the width B of the frame 3.

[0043] In order to be able to pull out the relaxed belt or belt 7 (circular conveying mechanism) from the right side of the belt conveyor 1, the side part 15 on the right side as seen in the x direction has a small height in the z direction (and also a smaller length in the x direction), preferably smaller than the diameter of the drive roller 9.

[0044] The opposite side part 17 can have a greater height, for example, for stability reasons. A motor 11 is provided on the side part for driving the drive roller 9, which is installed between the side parts 15 and 17 at the front end when viewed in the x direction. Obviously, the motor 11 can also be arranged in the drive roller 9.

[0045] In the tension state, Figure 1 The two belts 7 shown are acted upon by drive rollers 9 and the upper belt section is thus driven in the conveying direction x.

[0046] Each belt has at least one deflection roller 35 located at the end of the belt conveyor 1 opposite to the drive roller 9 (see Figure 2 ).

[0047] Unlike the driving roller 9 , the deflecting roller 35 is not directly rotatably mounted in the frame 3 , but is rotatably mounted in the cassette transport unit 23 which can be inserted into and removed from the frame.

[0048] In the installed state, the cassette conveyor unit 23 is fixed in a correct position at least in the longitudinal direction x and the transverse direction y, but can be removed upward or obliquely upward as shown in the figure when viewed in the z direction. The cassette conveyor unit 23 is placed in or on the frame 3, in particular the transverse parts 19, 21, against the height direction z and is fixed by the tensioned belt 7 to prevent movement in the height direction z.

[0049] As from Figure 4 In particular, from 5 and Figure 6 As can be seen in the figure, the cassette transport unit 23 has mutually parallel outer parts 27, 29, viewed in the x direction, which are connected to form a rigid frame by front and rear spacers 43, 45 extending in the transverse direction y.

[0050] In the side parts 27, 29, a plurality of guide rollers 47, in the embodiment shown, six, are rotatably mounted on different, preferably equidistant bearings for guiding the upper belt section of the belt 7. The guide rollers 47 can be inserted from above with their axle heads into grooves or bearings which are designed, for example, in a U-shaped manner and are fixed by the belt 7 which is wrapped around the cassette conveyor unit 23 in a tensioned state to prevent them from coming loose from the bearings.

[0051] If available from Figure 5 As can be seen in FIG. 2 , the side sections 27 , 29 of the cassette transport unit 23 are connected to other, preferably equidistant, lateral sections 31 in order to increase the stability of the cassette transport unit 23 .

[0052] Parallel to the side parts 27, 29, two central connecting bars 39, 41 are formed in the inner area of ​​the box conveying unit 23 below the rollers 47 and the transverse part 31, which are connected to the front spacer 43 in a fixed position at their front end and to the rear spacer 45 at their rear end when viewed in the x-direction.

[0053] As from Figure 6 As can be seen in the figure, the end sides of the central links 39, 41 are designed as right-angled stops or stop surfaces, wherein the vertical section (extending in the z direction) serves as a stop in the x direction and the horizontal section (extending in the x direction) serves as a stop or support (against the z direction) relative to the transverse sections 19, 21. In the installed state of the cassette conveyor unit, the front end sides of the central links 39, 41 are respectively connected to the transverse section 19 with a vertical section under tension of the belt, so that the installed cassette conveyor unit is fixed in the x direction. In the height direction z, the cassette conveyor unit placed on the transverse sections 19, 21 is fixed in the tensioned state of the belt 7 surrounding it (similar to the guide roller 47).

[0054] Also at the rear end of the cassette transport unit 23, as seen in the x-direction, there is a carriage 33 which is movable in the x-direction, in which a deflection roller 35 and preferably a further deflection roller 37 are rotatably mounted. The further deflection roller 37, which is arranged obliquely below the deflection roller 35, serves in this embodiment to compensate for the significantly larger diameter of the drive roller 9 and allows the upper and lower belt sections of the belt 7 to be guided in parallel, which is advantageous from a space-saving perspective.

[0055] The carriage 33 can be moved by a pneumatic cylinder 49 between a retracted position (belt slackened) and an extended position (belt tensioned).

[0056] If available from Figure 6 and Figure 7 As can be seen in the figure, the pneumatic cylinder 49 rests with its bottom point on the wing of the rocker 53, which is mounted rotatably about the axis of rotation in the y direction between the central links 39, 41. At its opposite end, the cylinder and the front transverse part 57 of the carriage 33 are arranged. If the cylinder 49 is retracted to relax the belt 7 at the deflection rollers 35 (and 37), this causes a rotational movement of the rocker 53, so that its wing 55 (stop roller) turns downward and cooperates with a pressure piece or a pressure part (not shown in the figure) of the frame or machine base to reliably and immediately stop the movement of the lower belt section of the belt 7 and thus stop the product conveyance.

[0057] Furthermore, the carriage 33 has a rear transverse portion 59 which, like the front transverse portion 57 , is also connected to the side wall of the carriage 33 in the transverse direction y.

[0058] The transverse sections 57, 59 extend through the front and rear elongated holes 61, 63 and 61', 63' formed in the central webs 39, 41 and serve as guide means for the movement of the carriage 33 in the x-direction. In addition, supports are provided at the transverse sections 57, 59 as counterparts to the elongated holes 61, 63 and 61', 63', for example in the form of cylinders with cutouts, grooves or the like, which prevent the movement of the carriage 33 in the y-direction.

[0059] Figure 5 and Figure 6 The illustrated spacers 51 are respectively arranged, for example screwed, on the central webs 39 , 41 and extend outwardly in the transverse direction y. The spacers 51 thus serve as lateral spacing between adjacent cassette transport units 23 and / or relative to the frame 3 .

[0060] The length of the spacer 51 can be selected and installed depending on the desired distance from the outer parts 15 , 17 of the frame 3 or the adjacent cassette transport units 23 .

[0061] It is of course also conceivable that adjacent cassette transport units are positioned in a defined manner relative to one another by means of further stops or by means of stops or grooves in the frame 3 also in the transverse direction y.

[0062] Different from the first embodiment having two cassette transport units 23, Figure 8 and Fig. 9 The second embodiment shown shows a belt conveyor according to the invention with four installed cassette conveyor units 23 , wherein the above description, except for the changed number of cassette conveyor units 23 , also applies to this embodiment.

[0063] In this case, four cassette conveyor units 23 with a smaller width are installed in the frame 3, so that four physical lanes are obtained. It is obviously also conceivable to install another number of cassette conveyor units 23 with corresponding widths, for example three or five. It is also possible to install cassette conveyor units 23 with different widths in the frame 3 and preferably occupy the entire frame width. However, it is also conceivable that the entire frame 3 is not occupied, but that gaps are allowed.

[0064] The cassette conveying unit 23 is as follows Fig.10 and Fig.11 The embodiment shown differs from the previously explained embodiment of the cassette conveyor unit in that in this embodiment the cassette conveyor unit comprises a weighing unit 65. The weighing unit 65 is Fig.10 The illustrated arrangement is between the central webs 39 , 41 and is fixedly connected thereto.

[0065] Seen in the z direction, the weighing unit 65 supports a weighing platform 67, which is arranged between two rollers 47 and the belt 7 is guided through it, so that the weight of the product conveyed on the belt 7 is weighed in this area, or the weighing platform 67 acts as a bearing member. Obviously, other bearing forms can also be implemented to weigh the product. For example, it is conceivable that the parts of the cassette conveying unit 23, especially the outer parts 27, 29 and the transverse part 31 are designed as bearing members or weighing platforms of the weighing unit 65 fixed on the center connecting bars 37, 39 (fixed seats). Multiple weighing units can also be arranged in a cassette conveying unit and jointly support a weighing platform.

[0066] Fig.11 The frame 3 is shown without the drive rollers 9 only for illustration purposes, but is otherwise designed identically to the frame of the preceding embodiment.

[0067] Weighing can be performed in a dynamic manner (without interruption) or in a static manner (start-stop manner, preferably using the aforementioned stop rollers or flaps 55).

[0068] In any case and independently of the embodiment shown by way of example, according to the invention, after the removal of the respective belt 7 , the corresponding cassette transport unit 23 can advantageously be removed from the frame 3 without having to remove other, in particular adjacent, cassette transport units 23 for this purpose.

[0069] Cleaning and repair of the belt conveyor or desired replacement of defective components is thereby facilitated, as is a desired change in the track width and / or the number of tracks.
