Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a method and an apparatus for attaching a label sleeve to an object.

[0002] A corresponding machine is known from EP 0 584 516. The machine has trays for receiving bottles in a free standing manner, equally spaced on a common pitch circle. Above each of these trays, respectively, a label tube roll, a label sleeve release device, and a liftable for gripping the separated label sleeve and placing the label sleeve over the bottle A pair of spreading grips are arranged to rotate together.

[0003] This arrangement has the disadvantage that it requires a very high outlay and requires a lot of time for changing a large number of label tube rolls. Because the bottles are self-supporting, the rotational speed and thus the production capacity is severely limited. Furthermore, on the one hand, the uniformity of the mounting height of the label sleeve on many bottles is insufficient, and on the other hand, the reliability of the operation is reduced, especially when the outer walls of the bottles are wetted with liquid. This is related to the label sleeve ending its axial relative movement to the bottle and adhering to the bottle at the moment the friction between the label and the bottle is greater than the friction between the grip and the label. are doing. The mounting height of an individual label sleeve is a function of the individual friction situation and is therefore not precisely defined. Furthermore, there is a problem in terms of work reliability, since during the return of the spreader grip to its initial upper starting position, the bottle is still on the tray supporting the bottle.

It is an object of the present invention to provide a method and an apparatus with higher mounting accuracy and work reliability. This object is achieved by means of the features of claim 1 for the method and by the features of claim 9 for the device.

In accordance with the present invention, the bottle is gripped and held securely in the peripheral area of the bottle before the label sleeve is placed thereon, and the spreader gripper holding the label sleeve descends from above in a known manner. Is secured until it surrounds at least a portion of the bottle's longitudinal extension. In the next step, the holding of the outer peripheral surface of the bottle is suspended, and the label sleeve is spread over the bottle to the desired final position by means of an unfolding gripper, with the bottom of the bottle supported at the same time. The lowering movement of the pair of grippers is then stopped, but the label sleeve is still held at its lower edge by frictional engagement by the pair of grippers. Here, the bottle is gripped again at the outer peripheral portion of the label sleeve covered by the label sleeve interposed therebetween, in which case the label sleeve is fixedly held by frictional engagement or outside the bottle. It is crimped. Only then does the spreading gripper pair release the clamping of the leading lower edge of the label sleeve and is now completely lowered below the free-standing surface of the bottle. During this downward movement of the unfolding pair, the height of the label sleeve no longer changes, so that in many bottles the position of the label sleeve with respect to the bottom of the bottle remains uniform and very accurate Advantageously, the height position tolerance of the deposition height can be kept within a very narrow range.

[0006] During the application of the label sleeve, the label sleeve at its lower edge
Not only on the radially inner surface but also on the outer surface is simultaneously clamped and held fixed by frictional engagement, so that the label
Advantageously, the unfolding gripper pair is designed such that unnecessarily large opening of the sleeve can be avoided.

[0007] In the proposed method, the bottle is always generally supported in the outer peripheral area of the bottle before, during and after the application of the label sleeve, so that the bottle is not overturned. High rotational speeds with correspondingly high production capacities can be achieved.

According to a modification of the invention, the spreading gripper is raised from its bottom dead center position to its initial upper position only after the label sleeve has been loaded and the bottle has been ejected, so that the bottle or spreader is opened. Advantageously, no damage is caused by collision between the suspended part of the gripping pair and the label sleeve.

The vertical movement of the clamp gripper pair for covering the label sleeve and returning to the starting position is controlled by a cam control, but is effected by a working cylinder or other suitable drive (such as a motor). The design is particularly preferred. The reason for this is that the actuation time, in particular the return time to the starting position, can be made shorter than in the case of pure cam control, since there is no risk of self-braking. The angle of rotation of the rotary table required for a complete movement cycle of the clamp gripper is thereby reduced, ie a smaller table diameter is sufficient for the same capacity.

[0010] Other advantageous embodiments of the invention are evident from the dependent claims. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. The machine 1 shown in FIG. 1a consists essentially of a horizontal table plate 2, on which a rotary table 3 with a plurality of bottle trays 4 equidistantly arranged on a common pitch circle. It is supported rotatably about a vertical axis 3 '.

Are mutually rotated by the mechanical drive device and the transmission element. The cutting device 10 also has a drive for precise movement of the position of the label foil tube in synchronization with the rotary table movement and for cutting the label sleeve E by the cutting tool of the device 10. With regard to the structures concerned, reference is made to the above-mentioned German patent publication.

Hereinafter, the structure of the turntable 3 will be described in detail with reference to the longitudinal sectional views shown in FIGS. 4 and 5A. The base of the turntable 3 forms a horizontal support plate 30 which is fixed at its center to the vertical spindle 31 of the machine so as not to rotate and has a bottle tray 4 above it (shown in the left half of FIG. 4). Has not been). Each of the bottle trays 4 is provided with a pair of parallel guide rods 32 that are vertically neutral on the upper side of the support plate 30, and the guide rods 32 correspond to the pitch circle on which the bottle trays 4 are arranged. Present radially inward. An end of the guide rod 32 facing upward in a direction away from the support plate 30 supports a ring disk 33 having a center vacant provided in parallel with the support plate 30, and a pair of guides is provided on the ring disk 33. Rod 32
A reciprocating pneumatic cylinder 34 with an associated control valve 60, arranged centrally in between, is fixed vertically upright. In order to ensure a stable holding of the cylinder 34, the housing end of this cylinder, which faces vertically upwards, is joined by a second ring disk 35 which is also centered. The piston rod 36 of the reciprocating pneumatic cylinder 34 can protrude downward in a vertically parallel manner between the pair of guide rods 32. In this case, the piston for each pneumatic cylinder is provided in the first ring disk 33. A centrally located hole is provided between the guide rods 32 so that the rods 36 pass freely.

The downwardly facing end of the piston rod 36 is fixed to a slider 37 having two parallel inner holes, each penetratingly engaged by a guide rod 32, and the slider 37 is attached to the main shaft 31.
The upper and lower cam rollers 38 to 39 are provided on the back side of the cam rollers 38 and 39 facing in the direction of. The cam rollers 38 and 39 are rotatably fixed to swing levers 38b to 39b, respectively (FIG. 6), while the swing levers 38b to 39b are supported by a slider 37. Within the swing range of these levers, shock absorbers 38c to 39c having stoppers are fixed to the slider.

The upper cam roller 38 abuts on a control surface of an upper control cam 40 which is bent in a cylindrical shape, and the control cam 40 is fixed around a horizontal disk 42. This disk 42
Has a tubular projection, and the tubular projection is supported on the upper end of the main shaft 31 by a rolling bearing. Below the disk 42 there are a plurality of equally spaced circumferentially suspended spacer bolts 44. A ring disk 43 whose center is vacant is fixed to the lower end of the spacer bolt 44, and the ring disk 43 is centered and fixed to support the lower control cam 41 for the lower cam roller 39 around the ring disk 43. I have. Further, the lower control cam 41 is held so as not to rotate by a clamp member 45 attached to the spacer bolt 44. Similarly, the lower control cam 41 having a cylindrical shape has a control surface facing upward, and the cam roller 39 rolls on the control surface.

The cam trajectories of both control cams 40 and 41 are evident in detail from the development shown in FIG. 8, in which case the running direction of the cam rollers 38, 39 is marked with a 0 ° mark (FIG. 1).
(see also b) from right to left in the direction of the arrow. The lower control cam 41 is raised to allow the machine 1 to handle various bottle types and / or label sleeves E, which may have different deposition heights, i.e., lower edge positions of the label sleeve relative to the bottom of the bottle. It has a continuously adjustable cam section 41b (see FIG. 8), the control surface of which determines the height of the label sleeve E on the bottle F. This cam member 41b is connected to a slide bush 48 movably guided on two spaced spacer bolts 44, respectively, and can be raised and lowered continuously by a screw spindle (not shown).
(Fig. 4).

In order to prevent the control cams 40 and 41 from rotating together, an angle-shaped rotation prevention stay 46 is fixed on the upper side of the disk 42, and the rotation prevention stay 46 is
On the outside of the rotary table 3, it is supported by stationary columns 47 vertically arranged on the table plate 2.

The bottle trays 4 arranged on a common pitch circle of the support plate 30 are mounted with a fixed height, and are each coaxially centered with a spring biasably supported in a height direction.
4, the centering ring 14 surrounds the bottle tray 4 and
It has an edge that projects upwardly and is contoured to the bottom of the bottle. The centering ring 14 is connected to a bar 15 movably guided in a vertical direction within the support plate 30, the lower end of which protrudes from below the support plate 30 and the cam roller 17.
(FIG. 5a). The control cam 18 is fixed to the table plate 2 so as not to rotate in the rotation orbit of the cam roller 17 below the support plate 30, and the control cam 18 rotates in a rotation range from the carry-out star wheel 6 to the carry-in star wheel 5. At this time, the cam roller 17 acts to lower the cam roller 17 against the restoring force of the coil spring 16 which always acts upward in the vertical direction. Here, the upper end edge of the centering ring 14 is held from the upper side of the bottle tray to the lower side when the bottle F is supplied to the bottle tray 4 and discharged from the bottle tray 4 (FIG. 2C).

Each of the bottle trays 4 is further provided with shafts 19 a, 19 b, which are vertically spaced apart and parallel to one another and rotatably supported in a support plate 30. At their upper ends, each of these shafts supports a gripping arm 20a-20b that projects horizontally radially outward and is held against rotation, and the gripping arms 20a-20b cooperate to hold the label. A controllable gripper 20 for gripping and holding the bottle F to be attached on the bottle tray 4 is formed (FIG. 9). A lever 21a provided with an elongated hole 22 at the lower end of the shaft 19a, and a shaft 19b
A lever 21b provided with a vertical support bolt 23 is attached to the lower end of the lock member so as not to rotate. The support bolt supports a swingable slide block that penetrates the elongated hole and a cam roller 25 whose height is offset.
It abuts against a radially outer control surface of a cam ring 26 which is held against rotation on the table plate 2. A tension spring 27 is engaged with both levers 21a and 21b, and the tension spring 27 always acts in a direction to close the gripper 20. The shape of the cam ring 26 with two cam sections projecting radially outward is shown in FIG.
It is clear from As it passes through this section, the cam rollers 25 are pressed outward, in which case the gripping arms 20a, 20b swing in opposite directions. The various positions of the grippers 20 are apparent from FIG.

From FIG. 7, the structure of the spreading gripping unit 50 for gripping the label sleeve E by frictional engagement and placing it on a bottle F, for example on the body of a plastic bottle, is evident. The spread grip unit 50 is composed of two internal grips 51a, 51b and opposed arms 52a, 52b attached thereto. Each inner grip consists of a horizontal support surface 53 for the lower edge of the label sleeve and a vertically upwardly bent half shell 54, the curvature of which is adapted to the bottle diameter. The half shell that rotates from the rear in the rotation direction of the turntable 3 may have a lower height than the half shell that rotates forward. The similarly curved opposing arms each have two elastic rubber cushions 5 which can abut against the half shell from the radial outside.
5 and rubber cushion 55 is adjustable with screws to evenly grip the label sleeve. Two vertical support bolts 57 for internal gripping and two other vertical support bolts 58 for the opposing arm are fixed on a support plate 56 which is inserted in the slider 37 so as to be quickly exchangeable in the horizontal direction. In this case, the support bolt 58 is freely penetrating into two curved slots in the inner grip. Each rotary joint 66 causes the opposing arms to swing such that the approaching movement of the inner grips causes the opposing arms to swing away from each other and vice versa. , Each of which is coupled to an internal grip attached to the opposing arm. In the vicinity of the half-shell, a tension spring 61 is engaged which draws the inner grips together. Approximately in the center of the support bolt 58 there is a control cam 68 fixed against rotation on a shaft 62 supported horizontally in the slider 37, the control cam 68 being at its height between internal grips. Positioned. At the opposite end of the same shaft, a control segment 67 having a total of three cam rollers 63, 64, 65 is mounted non-rotatably. The control cam formed symmetrically by the two cam rollers 63 and 64 arranged on the side of the control segment remote from the slider is rotated clockwise or counterclockwise by about 90 ° by the cam member 70 arranged on the rotating track. While the third cam roller 65, which is on the side of the control segment facing the slider, moves the label holding position of the spread grip unit 50 during the downward movement of the spread grip unit 50 when it is placed on a bottle. Used to maintain. For this purpose, the cam roller 65 is provided with a vertical longitudinal guide member 71 which rotates together with the rotary table 3, and the cam roller 65 rolls along the guide member 71 during descending.

Contrary to the embodiment described above, as shown in FIG. 1b, the opposing arms may each be rigidly fixed in a corresponding configuration to an inner grip with one end diametrically facing.

In the following, the course of this method during the passage of the bottle through the machine will be explained mainly with reference to FIG. 1a. The bottle F arriving at the supply conveyor 7 is gripped by the pitch forming screw 8 and fed to the incoming star wheel 5 in the correct position, gripped by the controlled clamps of the incoming star wheel 5 and at a common contact point I the rotary table 3 is positioned on the bottle tray 4, in which case the centering ring 14 is simultaneously slid up and the associated gripper 20 is closed. At that moment, the corresponding clamp on the incoming star car releases the bottle.

At the same time, the spreading gripping unit 50 attached to the bottle approaches the cutting device 10 by a lifting movement, at which point the half shell 54 and the rubber cushion 55 are spaced from one another. At the same time, the label tube 11 is pushed downward from above and the label sleeve E is cut, the label sleeve E now having its lower edge abutting on the support surface 53 of the inner grippers 51a, 51b, That is, the half shell is inside the label sleeve, and the rubber cushion is outside the label sleeve. Rotating with the turntable within the height of the label sleeve E just cut from the tube to prevent the label sleeve from tipping over when the label sleeve is taken up and accelerated in the direction of rotation of the turntable 3; A concavely curved support shell 49 abutting the rear side of the label sleeve as viewed in the direction of rotation.
The support shell 49 is mounted on the radially outer edge of the ring disk at a fixed height by a bracket (FIG. 5b). FIG. 5c shows the shape of the support shell 49 in plan view.

Immediately thereafter, the half shells 54 swing away from each other and at the same time the rubber cushion 55 moves in the opposite direction inward until the label sleeve is frictionally clamped from the outside and the inside at its lower edge. The shaft 62 having the control cam 68 is rotated so as to swing. In the case of an elongate sleeve, the elongate sleeve is now expanded to a size beyond the bottle diameter.

When passing through sector II (FIG. 1a), the label sleeve is
The bottle F is moved downward from above by the spread gripping unit 50 crimped downward by
On top of. As soon as the spreading gripper approaches the gripper 20 which holds the bottle during the lowering movement, the gripping shears will be short enough to allow the spreading grip to pass between the grippers. Opened (second half in sector II). Thereafter, the bottle is generally guided, but the grippers 20 may be reclosed to a width that leaves enough clearance to further withdraw the label sleeve. As soon as the label sleeve has reached the required deposit height, the lowering movement of the spreading grip is stopped, the gripping shears 20 are completely closed (the label is crimped on the bottle cylinder) and the half-shell 5
4 is slightly swung inward (the tightening of the lower edge of the label is released). This process is performed in sector II.

Furthermore, before reaching the export star 6, the unfolding gripping unit 50 is further lowered until the half shell is completely under the bottle tray 4 (FIG. 2 c). In the case of a shrinkable sleeve, preliminary shrinkage (hot air or the like) for fixing the label on the turntable 3 may be performed at this time. Further, at this time, the centering ring 14 is lowered, and the gripper 20 is opened when the output star wheel 6 grips the bottle to convey the bottle to the discharge conveyor 9.

Thereafter, the pneumatic cylinder 34 is switched up, so that the spreading gripper unit 50 again reaches its initial upper position before passing through the incoming star 5 (sector IV).

During the entire process, the bottles are transported by the machine without changing the height position. FIG. 10 shows a modification for increasing the output capability, which is shown in FIG.
1b are formed by arranging two individual machines in mirror symmetry, i.e., these double machines are two input star wheels 5 and 5 ', two turrets or rotary tables 3 and 3' and It has two output star wheels 6 and 6 ', but only one common supply conveyor 7, one discharge conveyor 9 and one pitch forming screw 8. Opposite star wheels 5, 5 'to 6, 6', driven in opposite directions, each contact one of a pair of pitch circles and have a controllable clamp around them as shown in FIG. The clamp is selectively switchable from an engaged position for gripping the bottle to a disengaged position and vice versa by a switching cam (not shown) fixedly arranged at a predetermined position on the rotational path of the clamp. The pitch dimension, i.e. the distance between two adjacent bottle trays 4 on both rotary tables 3 and 3 ', is two times the pitch dimension of the incoming star wheels 5, 5' and the outgoing star wheels 6, 6 '.
It has twice the size. Bottles supplied from the supply conveyor 7 with a single line without gaps
They are separated from each other by the pitch forming screw 8 in accordance with the pitch dimension of the carry-in star 5, and are gripped by the carry-in star 5. At the common point of contact of both incoming star wheels 5 and 5 ', every other bottle F is released from the first incoming star wheel 5 and simultaneously grasped by the second incoming star wheel 5'. It is. In this way, bottles F and F 'are alternately supplied to both turntables 3 and 3'. Labels, foils, and labels are placed on each turntable in the delivery area of the carry-in star car on each turntable.
A cutting device 10 to 10 'for detaching the label sleeve E from the tube is provided. On the unloading side, completely labeled bottles F and F 'alternately coming out of both rotating tables 3 and 3' are fed by both unloading star wheels 6 and 6 '.
And at the common point of contact of 6 'and again in a row and are delivered from the output star wheel 6' to the discharge conveyor 9. With this modular structure, a larger throughput range can be covered with just two variants. Instead of a clamp star wheel, it is possible to use an alternative method with a holding device for selectively gripping the bottle, which is designed in another way, for example a transport device such as a vacuum star wheel Is clear.
