Apparatus and method for making a grill torch

description

The invention relates to a device for producing a grill torch and a corresponding method.

A grill torch is understood to mean strips of meat, in particular made from the belly meat of a pig, which are attached to a skewer with both ends and are wound spirally around the skewer between their ends.

The grill torches are usually made by hand, which is time-consuming. DE 20 2008 008 871 U1 has disclosed a device with which at least partial mechanization is achieved with regard to piercing the skewer and the winding process. The ones to be processed

However, strips of meat must still be touched by hand and placed in a U-shape. The interposition of human intellectual activity is also required to remove the finished grill torch from a winding device and to put it on a conveyor for removal.

DE 10 2008 024 201 B3 proposes a grill torch machine suitable for complete mechanization. The skewers to be processed are inserted horizontally with their axis of rotation in skewer holders, each of which has a rotary drive and is arranged on a circulating transport device. The ones suitable for full mechanization

Embodiments provide either molded parts between each of which a strip of meat is inserted before a skewer is pierced, or a relocation of the strip of meat on a support pin and subsequent rotation of the support pin transversely to the longitudinal direction of the skewer. Both should by means of a gripper moving synchronously with the lifting pin End portions of the meat strip recorded, raised in front of the free end of the skewer and pushed together on this. After the meat strip has been pushed onto the skewer, the gripper and the lifting pin can be removed. The meat strip is wrapped around the skewer by turning the skewer holder together with the

adjacent end of the meat strip while holding the opposite end of the meat strip. In practice, however, it has been shown that too many assemblies are involved in the transport, shaping, piercing and winding of the meat strip, which can hardly be synchronized with one another and result in a high reject rate

have fallen or miswound strips of meat. Particularly high losses occur with strips of meat with a high fat content, which can hardly be accurately positioned using molded parts or grippers.

The invention was therefore based on the object of developing a completely automated device for setting off a grill torch, which has a high production output of grill torches with as little as possible

Rejection rate enabled.

The object is achieved according to the invention with the features of claim 1. By means of the transport conveyor, for example a belt conveyor or belt conveyor, the strips of meat to be processed into a grill torch are brought one after the other to a skewer holder. A skewer is releasably held in the skewer holder via a clamping element. The

The clamping element can be guided linearly between a rear and a front dead center by means of a guide rail. In the forward movement, the clamping element approaches the transport conveyor in such a way that a skewer fixed in the clamping element is pushed through both end sections of a strip of meat that is still on the transport conveyor. A gripper arranged on the other side of the skewer holder with respect to the transport conveyor takes over the skewer in a front position with respect to the skewer holder. The gripper is preferably on one Arranged gripper slide, which is linearly guided on gripper guide rails and can be moved between the front and a rear position. The gripper is also about its linear movement axis via a gripper shaft

rotatably mounted. A linear displacement of the gripper causes the meat strip to spread over the axial extent of the skewer. The rotary movement of the gripper is used to wind the

Strips of meat around the skewer. The linear and rotary movement of the gripper can take place simultaneously or one after the other. An embodiment is particularly preferred in which the linear travel path and the number of rotary movements of the gripper can be set independently of one another.

The clamping element is preferably guided in the same linear movement axis of the gripper. Both axes of movement of the clamping element and gripper are aligned with one another. The advantage of this embodiment is that the skewer pushed forward by the clamping element of the skewer holder in the direction of the gripper can be gripped particularly accurately by the gripper arranged in a front position. Alternatively, it can also be provided that the axes of movement of the clamping element and gripper are aligned offset parallel to one another.

The skewer holder is advantageously arranged opposite one another on a first side and the gripper on a second side of the transport conveyor. This arrangement favors an automated piercing of a skewer from the first side and a subsequent winding movement by means of the gripper from the second side.

It has proven to be particularly useful if the skewer holder and the gripper are arranged in the vertical direction below the transport conveyor. Through this it is possible to have a strip of meat with due to the

Gravity from the transport conveyor hanging down end sections bring them to the skewer holder and gripper, whereby additional shaping Trays for aligning the meat strip with respect to the skewer holder and gripper can be dispensed with.

A section of the skewer expediently protrudes beyond the front position of the gripper in the front dead center of the clamping element. This feature enables a secure frictional connection of the gripper with the skewer, since the skewer protrudes sufficiently far into the action space of the gripper located in its front position.

In an open position of the clamping element, a skewer can be received from a skewer magazine arranged above it and in a

Be fixed in the closed position of the clamping element. The opening position of the clamping element is typically in the area of the rear

Dead center, with the lowest spit of the

Spit magazine falls into the clamping element and is fixed there by clamping.

Advantageously, several skewers are stacked in one row in the skewer magazine. Due to the single-row stacking, there is exactly one skewer above the

Clamping element held ready and received by the clamping element in the open position. The skewers held in reserve in the skewer magazine are aligned parallel to the axis of movement of the clamping element and / or gripper.

According to a particular embodiment of the invention, this is

Clamping element formed from two clamping jaws, between which in the

Open position a skewer can be used. The distance between the

The clamping jaw is variable between the open position and a closed position.

The skewer is preferably fixed by the clamping element in the closed position on its side facing the gripper. The spit is from that

Clamping element held adjacent to its tip, so that when Piercing of the meat strip occurring compressive stress is minimized.

An embodiment is particularly advantageous in which the skewer holder has a baffle plate, which by means of a parallel to the linear

Movement axis aligned linear guide is guided between a rear with respect to the transport conveyor and a front reversal point.

The front reversal point of the baffle moves under the

Transport conveyor and makes contact with an end section of the still lying on the transport conveyor which is close to the skewer holder

Strips of meat.

The distance between the rear and the front makes sense

The reversal point of the baffle plate is less than the distance between the rear and front dead center of the clamping element. This results in a smaller range of motion of the baffle plate compared to the clamping element. When the clamping element moves from its rear to the front

Dead center, the clamping element can take the impact plate with it and / or trigger an advance of the impact plate.

On the side of the baffle plate facing away from the linear guide, a cannula with a guide channel running completely through the baffle plate can be formed. By moving the baffle plate in the direction of the

Transport conveying means and thus in the direction of a first end section of a meat strip depending therefrom, the cannula penetrates the first end section of the meat strip. The guide channel is aligned with the cannula and the axis of movement of the clamping element in such a way that the

Clamping element pushes the skewer through the already perforated first end section, thereby keeping upset forces away from the skewer and

Damage to the skewer is significantly reduced. A fixing pin is expediently formed on the baffle plate at a radial distance from the cannula. The fixing pin is a point which protrudes with respect to the impact plate and is suitable for penetrating the meat strip next to the cannula and the first when the gripper rotates

End section of the meat strip against turning in order to hold the cannula in place.

The baffle plate is preferably kinematically coupled to the drive device. Flierdurch the clamping element and the baffle plate are driven by the same drive device, whereby the number of

Can reduce drive devices and no synchronization of separate drive devices is necessary. In principle, however, it would also be possible that the baffle plate separately from a pneumatic or

electric drive device is driven.

The skewer holder should have a counter-holder plate movably arranged between the baffle plate and the gripper. The counter-holder plate forms an abutment for the first from the opposite side of the baffle plate

End portion of a meat strip and prevents the meat strip from escaping in the direction of the gripper during a perforation.

According to a further embodiment of the invention, the baffle plate overlaps in the direction of the gripper before it reaches its front reversal point with respect to the counter-holder plate moved into a functional position

arranged. Under an overlapping arrangement, the

Axis of movement understood an at least partial overlap of baffle plate and counter-holder plate. Still, the baffle and

Counter-holder plate spaced from one another in the axis of movement to clamp the first end portion of a meat strip therebetween

record. A recess is advantageously formed on the counter-holder plate, into which the cannula and / or the fixing pin protrude in the functional position. This avoids the cannula and / or the fixing pin colliding with the counter holder plate and being / are damaged.

It makes sense that the backing plate is kinematic with the

Drive device coupled. This can be done, for example, in such a way that the counter-holder plate is connected to the clamping element and guided in a link. When the clamping element is advanced from the rear to the front dead center, the clamping element can take the counter-holder plate with it and move it into the functional position along its link contour. In principle, however, it would also be possible for the counter-holder plate to be driven separately by a pneumatic or electric drive device.

The gripper can have several gripping tongs, which can be moved relative to one another between an open lancing position and a closed winding position. In an open lancing position, the gripping tongs are spaced from one another and allow the spit to pass through. In the closed winding position, the gripping tongs grip the skewer from opposite sides and clamp it both in its axial direction and in the direction of rotation about its longitudinal axis.

Preferably, the gripping pliers have one aligned parallel to the impact plate and / or to the counter-holder plate in the open lancing position

Contact section. This contact section forms an abutment for the second end section of the meat strip during a perforation by the skewer and prevents the second end section from being pushed away from the skewer during the perforation and thereby not being pierced at the intended location. In the front dead center of the clamping element, a skewer held therein advantageously protrudes into the open pricking position of the gripping tongs, so that the skewer does not collide with the gripping tongs. By moving the gripping tongs into the winding position, a section of the skewer facing the gripper can be held in a clamping manner by the gripping tongs in the closed winding position.

An embodiment is particularly useful in which the movement of the gripper along the linear axis of movement and the rotation of the gripper about the linear axis of movement can be controlled independently of one another.

This makes it possible to use skewers of different lengths and / or strips of meat of different lengths to make grill torches. For example, in the case of relatively long strips of meat and short skewers, a larger number of wraps can be made in order to wrap the meat strip around the skewer without excess.

The linear movement axis is preferably oriented transversely to a conveying direction of the transport conveyor. This embodiment simplifies the piercing of both end sections, which depend on the transport conveyor in an overlapping manner in the movement axis.

The transport conveyor can according to a further special

Embodiment run away under at least one co-rotating pressure means. The meat strips to be processed often come from a cold room and are dimensionally stable due to their low temperature. The

Pressure means improves the alignment of the strips of meat on the

Transport conveyor by pushing the laterally protruding first and second end sections into a vertical position. For this purpose, the pressure means can, for example, be a roller that runs downwards

Be transport conveyor towering side walls. As an alternative to this, the pressure means can also comprise several co-rotating rollers that are aligned at an angle to one another. The roles should be independent of the specific Embodiment always run along and do not have their own drive, otherwise there is an increased risk that the meat strips on the transport conveyor will be compressed or torn due to different relative speed (s). This in turn could make the automated piercing and wrapping of the meat strip around the skewer more difficult and increase the number of faulty grill torches being rejected.

The invention is also implemented in a method for Fierstellen a grill torch, in which a meat strip with both sides of one

Transport conveyor depending end portions is fed to a skewer holder. According to the invention, a gripper is brought up to the end sections in the open piercing position, a skewer is pierced through the end sections of the meat strip by means of the skewer holder, the skewer is clamped by the gripper, the gripper is linearly retracted from its front position to a rear position and rotates around its linear axis of movement . The linear retraction of the gripper and the rotation around the linear movement axis can be synchronized or in any order

take place one after the other.

According to a further, preferred method step, the one

Spit holder with counter-holder plate before piercing the

Skewer brought into a raised functional position between the end portions of the meat strip. This prevents the first one

End portion of the meat strip from the flapper or the skewer in

In the direction of the gripper and is not pierced at the intended point.

The counter-holder plate can advantageously be lowered into a rest position after the front dead center of the clamping element has been reached. This is useful so as not to hinder the winding process of the gripper and a subsequent release of the finished grill torch. In addition, the first end portion of the subsequent meat strip can hang freely between the skewer holder and gripper are conveyed without colliding with the counter-holder plate and twisting, as a result of which the

Meat strips in the intended position would hardly be possible.

If the skewer holder has a clamping element for releasably holding the skewer, the clamping element can expediently move between a rear and front dead center and the gripper can be moved into the front position after the clamping element has reached the front dead center. When the front dead center and the front position are almost simultaneously reached, the clamping element and gripper are minimally spaced from one another and the skewer is transferred to the gripper by opening the clamping element, which now has a maximum linear travel path from the front to the rear position for wrapping the strips of meat

Available.

According to a particularly favorable embodiment of the method, a second end section of the meat strip together with the skewer is held non-rotatably by the gripper during the retraction of the gripper from the front to the rear position. The gripper thus grips the

Strips of meat and the skewer so that both can be turned with little slip.

During the retraction of the gripper from the front to the rear position, a first end section of the meat strip can be held stationary between the counter-holder plate and a baffle plate. However, the end of the skewer belonging to this has already been released by the clamping element and can rotate freely with respect to the skewer holder.

In the course of the process, the skewer should be transferred from the skewer holder to the gripper. This means that the skewer is fixed exclusively by the skewer holder at the beginning of the process and in the direction of the gripper transported and is held exclusively by the gripper at the end of the process.

As a final process step, the gripper can be opened when the rear position is reached and the gripping tongs can be brought into the open lancing position, so that the grill torch consisting of a strip of meat and a skewer falls out of the gripper due to its gravity.

Fig. 1 shows in a perspective view a device for

Manufacture of a grill torch comprising a transport conveyor 10, a skewer holder 20 and a gripper 40, which are fastened together on a common machine frame 60. The machine frame 60 is stationary on feet 61 on the floor.

A meat strip 71 to be processed is fed in the conveying direction Y via the conveying means 10. The transport conveyor 10 of the exemplary embodiment shown is a belt conveyor. Belt systems or roller conveyors can also be used in the same way. A pressure means 11 is located above the transport conveyor 10

arranged, which the meat strips to be processed 71 in the

desired U-shape constrains. The pressure means 11 comprises a roller 12 which rotates passively, the axially spaced side walls 13 of which protrude downward beyond the transport conveyor means 10.

At the end of the conveying means 10 located in the conveying direction Y is on a first side A, in the image plane to the left of the Transport conveyor 10, the skewer holder 20 and on a second side B, in the image plane to the right of the transport conveyor 10, the gripper 40. The meat strip 71 hangs down with its end sections 72 (see FIG. 2) from the transport conveyor 10, so that they come into the area of action of the skewer holder 20 and the gripper 40.

The skewer holder 20 has, inter alia, a clamping element 21 in which a skewer 70 can be detachably fixed. The clamping element 21 moves back and forth between a front dead center x _Ki shown in FIG. 2 and a rear dead center x _K o shown in FIG. 3. In the region of the rear dead center x _K o, a skewer 70 passes from a skewer magazine 50 arranged above the skewer holder 20 into the one in an open position

Clamping element 21. The clamping element 21 can have, for example, two opposing clamping jaws 22 which, after the spit 70 has been picked up, move towards one another in the open position and thereby come to rest on the spit 70. The clamping jaws 22 can be seen particularly well in FIG.

In the skewer magazine 50, several previously separated skewers 70 are stored in one row and one above the other. When the skewer magazine 50 is opened, only the lowermost skewer 70 falls into the clamping element 20 due to its gravity. The skewers 70 held in the skewer magazine 50 are essentially horizontal and thus parallel to a linear one

Axis of movement X of the clamping element 21 between its rear and front dead center x _K o, X _KI aligned. In close proximity to that

A feed container 51 is arranged on the skewer magazine 50, in which the skewers 70 are loosely inserted. A separating device 52 is provided between the feed container 51 and the skewer magazine 50, which removes individual skewers 70 from the feed container 51 and places them into the skewer magazine 50 from above. The separating device 52 can

in particular comprise a rotatably driven wheel 53, on whose

Outer circumference driver elements (not shown) are formed. Further assemblies of the skewer holder 20 are, in addition to the clamping element 21, a baffle plate 23 that is linearly guided between a rear and front reversal point x _P0 , xpi and a counter-holder plate 28 that can be adjusted between a lowered rest position and a raised functional position 1 at its rear reversal point x _P0 and in the illustration of FIG. 4 at its front reversal point x _Pi. The counter-holder plate 28 is in a raised functional position in all of the representations except FIG. 2. The

Movements of the assemblies located on the skewer holder 20

The clamping element 21, baffle plate 23 and counter-holder plate 28 take place by means of a common drive device 30 which is connected to the clamping element 21 via a coupling rod 31.

The gripper 40 comprises two gripping tongs 41 which are movable relative to one another and with the aid of which a skewer 70 pushed forward by the clamping element 21 can be fixed in a clamping manner. The gripper 40 is attached to a gripper slide 42, which is guided in a linearly displaceable manner in the movement axis X by means of two gripper guide rails 43.

For a linear movement of the gripper carriage 42, a gripper belt drive 44, in particular a toothed belt, is placed on deflecting rollers 46 rotatably mounted on the gripper carriage 42, the belt loop resulting from the deflecting rollers 46 being indicated laterally offset for reasons of clarity in the illustration of FIG. The gripper belt drive 44 is designed as an endless belt and is driven by a gripper belt drive motor 45 which, depending on the direction of rotation, initiates a movement of the gripper slide 42 between a rear position x _G0 shown in FIG. 1 and a front position x _Gi according to FIG.

The gripper 40 also has a gripper shaft 47 which is of a

Rotary drive 48 can be rotated in the direction of rotation M, for example. The rotary drive 48 and the gripper shaft 47 are exclusively attached to the gripper slide 42.

2 illustrates in an enlarged, also perspective section, the interaction of the clamping element 21, baffle plate 23 and counter-holder plate 28. The clamping element 21 is on the way from the front dead center x _Ki to the rear dead center x _K o and has already released the spit 70 so that currently no skewer 70 is held in the clamping element 21 and the clamping element 21 moves back empty.

The baffle plate 23 has one or, as in the embodiment shown, two parallel linear guides 24, preferably two or more tubes pushed one inside the other, of which only the front one, however

Linear guide 24 is visible. The baffle plate 23 is mechanically with the

Clamping element 21 and / or connected to the coupling rod 31. In FIG. 2, the baffle plate 23 has already reached its rear reversal point x _P0 and releases the space below the transport conveyor 10 for end sections 72 of a strip of meat 71 conveyed thereon.

The counter-holder plate 28 is in a lowered rest position in which a strip of meat 71 located on the transport conveyor 10 can be conveyed between the skewer holder 20 and the gripper 40 without collision.

The gripper 40 is moved back into its rear position x _G o according to FIG. 2 and the gripping tongs 41 are brought into an open lancing position in which a spit 70 can be inserted between the gripping tongs 41.

Fig. 3 shows a standing in the area of the rear dead center x _K o

Clamping element 21 which, in its open position, is able to receive a skewer 70 from the skewer magazine 50 arranged above it. The position of the baffle plate 23 is unchanged from the illustration in FIG. 2; she is still at its rear reversal point x _P0. In the

Representation of FIG. 3 shows one of two guide rails 32 running parallel to the movement axis X, on which the

Clamping element 21 is guided axially by means of guide shoes 33.

The counter-holder plate 28 has been moved from the previous lowered rest position into the raised functional position and thus between a first end section 72a and a second end section 72b of the

Meat strips 71 arranged. The first end section 72a is arranged in spatial proximity to the skewer holder 20 and the second end section 72b in spatial proximity to the gripper 40. In the raised functional position of the counter-holder plate 28, a section is aligned parallel to the first and / or second end section of the meat strip 72a, 72b, whereby a

Contact surface is formed for the first end portion 72a.

In FIG. 4, the skewer holder 20 and the gripper 40 are shown at the time when a skewer 70 (not shown) is pierced by the meat strip 71.

The clamping element 21 of the skewer holder 20, together with a skewer 70 held between its clamping jaws 22 (see FIG. 6), has snapped forward to the front dead center x _Ki . On the way from the back to the front

Dead center X _KO , X _KI , the clamping element 21 has taken the baffle plate 23 with it and along its linear guide 24 to the front reversal point x _Pi

advanced. This is possible because a distance x _T (see FIG. 5) between the rear and front dead center x _K o, X _{KI of} the clamping element 21 is greater than or equal to a distance Xu (see FIG. 6) between the rear and front reversal point x _P0 , x _{Pi of} the baffle plate 23 is selected.

As can be seen particularly well in FIGS. 6 and 7, the baffle plate 23 has a pointedly protruding side on its side facing the meat strip 71

Cannula 25, which extends in the direction of the clamping element 21 Guide channel 26 connects. The cannula 25 and the guide channel 26 are aligned with the axis of movement X of the clamping element 21 and allow the spit 70 to pass in the axial direction through the cannula 25 and the guide channel 26. Radially spaced from the cannula 25, there is also a tapered fixing pin 27 opposite the impact plate 23 before. Both the cannula 25 and the fixing pin 27 pierce together with the

With a baffle plate 23 arranged at the front reversal point x _Pi , skewer 70 the first end section 72a of the meat strip 71. Due to the flat contact of the first end section 72a on the counter-holder plate 28 raised into the functional position, its evasion in the direction of the gripper 40 is avoided. The cannula 25 is complementary in the

Counterholder plate 28 formed recess 29 (see FIGS. 6, 7) and protrudes beyond both the counterholder plate 28 and the first end section 72a of the meat strip 71 in the direction of the gripper 40.

The gripper 40 was moved linearly together with its gripper slide 42 from its rear position x _G0 into the front position x _Gi . The

Gripping tongs 41 are also arranged in an open lancing position and contact the second end section 72b of the meat strip 71 at the end.

At their end close to the second end section 72b are the

Gripping tongs 41 each formed with a contact section 49, which comes to rest on the second end section 72b of the meat strip 71 and for the second end section 72b represents an abutment against the advancing cannula 25 and / or the fixing pin 27 and the skewer 70. The contact sections 49 have a flat wall section which is oriented at an angle to the rest of the gripping tongs 41 and parallel to the second end section 72b and thereby forms a contact surface for the second end section 72b. The gripper 40 and the clamping element 21 have approached each other exclusively in the linear movement axis X until the meat strip 71 is pierced with the skewer 70. 5 shows a situation in which the gripping tongs 41 of the gripper 40 have been brought into a closed winding position and hold the skewer 70 in a clamping manner. With the aid of its rotary drive 48, the gripper 40 is in

Direction of rotation M rotates and has that of the spit 70 on both

opposite end portions 72a, 72b pierced

Meat strips 71 wrapped around the skewer 70. During the rotation of the gripper 40, it is linear in the direction of its rear position x _G0

moved back and has pulled the opposite end of the skewer 70 out of the skewer holder 20. After opening the gripping tongs 41 from the closed winding position into the open lancing position, the

finished grill torch down out of the device.

In FIG. 8, method steps are particularly advantageous

Embodiment summarized. According to the invention, a meat strip 71 is first fed to the skewer holder 20 and the gripper 40 by means of the transport conveyor 10. In a second step, the

Counter-holder plate 28 moved into a raised functional position and the gripper 40 moved into a front position x _Gi . According to a third method step, the meat strip 71 is pierced and the skewer 70 in the direction

Gripper 40 advanced. A fourth method step provides that the gripping tongs 41 are moved into a closed winding position. In a further method step, the gripper 40 is rotated back into its rear position x _G0 and the meat strip 71 is wrapped around the skewer 70. Here, the skewer 70 is pulled axially out of the skewer holder 20. According to a last process step, towards the end of the

During the winding process, the gripping tongs 41 are brought into an open lancing position and the finished grill torch is released. List of reference symbols
