Removable head set for the closing head of a sealing machine

The invention relates to siel; tuf a detachable headset a capping machine, with a head block and a series of circularly around the axis of the head block arranged tools, each of which can be moved inwardly with respect to the axis.

Such capping machines are used to attach caps to bottles and other containers. The invention particularly relates to the application of metal closures to bottles or other containers.

In closing machines of the corresponding type, the closure is subjected to pressure that acts on it radially inward to deform the edge of the fastener or e.g. thread rolling process while

additionally on the top of the fastener on the face side pressure is applied, usually in one direction, along the longitudinal axis of the vessel.

For machines of this type it is desirable to have a basic model easy to turn off the use with several, different closure forines. It it has therefore become common practice to provide multiple interchangeable head sets that have tools of various shapes included in adaptation to the type of closure to be applied.

Numerous sealing machines are designed so that the. Rotate tools around the closure during the sealing of the closure. These tools or so-called Krejselrollers, which normally only roll due to their frictional contact with the lock, ^< roll thus cause a circular movement around the lock.

A single header can perform more than one operation at the same time. For example, V.'erK witnesses, which are arranged alternately around the circumference of the headset, the deformation processes on two different ones Make zones of closure. It should also be noted that headers do not apply to the use of Deformation capsules are limited, but also simple can be used for operations such as tightening screw caps.

723O78516.11.72

The head sets can be attached to the capping head of the capping machine in an exchangeable manner and in the In most cases it is required at least that Movement for the self-rotation of the tools of the head set of drive devices within the closing head derive. The closing head is therefore designed so that it has a regulated front end Put pressure on the top of the closure to be applied.

For extensive processing in which different or many capping heads are required to keep up with the production step 7 ι , it is useful to arrange the capping heads in a circle, each deriving its basic rotational movement from a central drive device. In such multi-head machines, it is desirable that each capping head URd each headset be as compact as possible in order to reduce the overall dimensions of the machine which are determined by the diameter of the circle on which the capping heads are arranged. Since the free space that must be left between the capping heads is normally determined by the width of the headset, it will be apparent that such modifications to the design of the headers which result in a reduction in size will have a significant effect on the reduction the overall dimensions of a multi-head machine.

Ei is provide ;, a head set for a sealing, animal he rmöglicht ~ to reduce the dimensions of the machine object of the present invention.

723078516.11.72

To solve this problem, it is proposed according to the invention for a header of the type mentioned at the beginning that that the head set is a series of arranged around the axis of the head block around. Cylinders contains that a piston is arranged in each cylinder, each piston und'Zylinder one of the tools it is assigned that each cylinder is connected to a duct for supplying pressure fluid, which drives the piston in a direction that a return device (spring) for resetting the Piston is provided in its initial position when the fluid pressure escapes from the cylinder, and that Transmission elements the movement of each piston in one direction in such a way on the associated tool transmit that this performs a movement directed inwards with respect to the axis.

The head set according to the invention can advantageously be designed such that an actuating arm for one Piston and the associated tool is provided, and that an axis of rotation is present in the block for each actuating arm is such that the piston movement in one direction by the actuating arm pivotable about the axis of rotation the tool is transferred.

In a preferred embodiment of the invention are four cylinders arranged around the head block and therefore four tools (usually rollers) for applying the closure intended. This is in contrast to some known headsets that use six tools are needed. The number of cylinders required can, however, vary by a suitable choice of the cylinder diameter; furthermore, a change in pressure

723078516.11.72

of the working fluid are required. The cylinders can be arranged on one level or on different levels Vertical levels lie around the numerous combinations of cylinder number and cylinder diameter adapt.

This first sentence is particularly suitable for the application of rolled up or puffed up Closures as well as removable closures. In this case, the independent attachment of the tools important, which have the form of freely rotating rollers, because ec is hereby possible the functions of thread rolling and edge rolling, which usually consists of rolls of different shapes that are arranged alternately around the closure, are caused to perform independently of each other.

The use of independently mounted roles also enables full compensation for each role in in relation to the diameter of the closure to be applied. The application of radial pressure to the The edge of the closure by the rollers is essentially constant because that exerted by the pistons Pressure regardless of the position of the piston in the Cylinder is. The head set is therefore able to adjust itself to irregularities in the container, without changing the degree of deformation.

The pressure exerted by the pistons can be changed by simple adjustment from a central location so that jode rolls can be finely adjusted, even while the machine is running, if necessary. In a multi-head machine, each roll can have one

-G-

every head sentence on this V />, ise from a central one Place controlled from / earthed. In contrast, must the normal side pressure systems include springs and adjusters for each of the roller arms can be set for each header. These settings must be made for each head set on each capping head of the Multi-head machine to be repeated.

It has already been mentioned that when using certain Locks the functions of thread rolling and Edge rolling of different roll shapes can be performed. It can be of advantage that Machines suitable for applying such closures have separate fluid pressure lines have, so that the pistons and cylinders assigned to a roller set are controlled independently of the other roller set can be.

From British patent specification 81? 172 it is already known, a detachable head set for a sealing machine for containers with a number of radially movable To provide sealing or application tools, each of which is a slide or one mounted on a slide Owns a tool (or a tool holder). DJe radially inward movement of the sliders is derived from the pressure-applying device, which its basic movement from an 'inside of the closing head of the machine is given an appropriate device. The head can therefore be an elastic element contain the air pressure supplied by the ducts is expanded as described in British Patent 817 171.

These cooperate with the lateral bearings 103 of the sealing head in such a way that the spanking i ^ ßkopi ^{17 for the} transmission of pressure acting on the face can be moved vertically on the top of the closure to be applied to the bottle 3.

At the upper end of the closing head 1 there is a head door 4 with an upright flange 5 and a housing 6. A bearing pin 7 is connected to the flange 5, which has a cam which engages in a neck track 107: o ·; The cam track 107 is part of a fixed central support 100 around which the revolver device rotates. Each closing head is therefore given a vertical movement when it rotates with the revolver device. The cylindrical housing 6 forms a cylinder 8 in which moves a piston 9. An air connection line 10 leads through the carrier k to the upper part of the cylinder 8. The piston 9 has a cup-shaped head 11 and a sealing ring 12 which is arranged in a groove running around its outer surface.

An upper pressure block 13 is located directly on the piston 9 screwed, which is surrounded on its upper side by a stepped washer 14. The washer 14 is screwed to the underside of the housing 6. The inner part of the annular disk 14 forms a lower stop for the movement of the piston 9 in the cylinder

The pressure block 13 also has a central blind hole 15, which emanates from its underside as well one connected to the blind hole] ^ transverse air duct l6.

The bore 15 receives the end of a tube YJ of the pressure socket, which bore 18 is provided with an axial center bore. The bore 18 is connected to the line 16 of the pressure block 15 via a short transverse bore 19 in the tubes 17. The part of the tube 17 surrounding the bore IQ is in the bore 1 |; sealed with sealing rings 20.

The pressure block 13 is stranded with a flange 21 to which a short tubular piece 22 is screwed i .'- t. The tubular piece 22 has an inwardly directed flange 23 which closely surrounds a threaded portion 2h of the tube 17. Upper and lower fastening nuts 25, 26 are screwed onto the threaded part 2h and are fixed on the flange 23 in order to fix the tube 17 of the pressure block with respect to the tubular piece 22. The tubular piece 22 is provided with an opening 27 through which one has access to the fastening nuts 25, 26.

A substantially tubular drive housing 28 is screwed tightly to the underside of the tubular piece 22. This carries in the vicinity of its end faces an upper and a lower roller bearing 29, 30, in which a drive spindle 31 surrounding the tube 17 of the pressure block is mounted. ^{A toothed element 3 2 is} mounted around the drive spindle 31, which by means of a wedge 32a is drivingly connected to the drive spindle

connected is. One side 33 of the drive housing 28 is cut away so that a generally designated 132 Drive wheel or the like. into the toothed element 32 can intervene. The drive wheel 132 is with the fixed support IOC connected, so that the toothed part 32 as a result of the rotation of the locking head with the turret device is rotated.

The toothing part 32 is fixed by upper and lower spacers J> H, 35 * which surround the spindle 31 and are supported on the upper and lower bearings 29, 30, respectively. The drive spindle 31 is axially fixed by two fastening nuts 36, 37 * screwed onto the upper end of the spindle 31 and engaging part of the bearing 29, as well as a step 38 of the spindle engaging part of the bearing 30. A bearing cap 39 is screwed tightly to the underside of the drive housing 28 and presses an oil seal 40 against the outer surface of the drive spindle 31.

The lower end of the drive spindle J> 1 is designed as a conical part 4l which engages non-rotatably in the inner cone of a hub 2 of the head set 2. The hub 42 has an external thread and is clamped to the spindle J> 1 with a union nut 43. The pressure tube 17 extends through the conical part 41 into a bore 44 of the head set.

The channel 18 through the tube 17 is through a plug 45 near the junction between the head and the Head set 2 blocked. Four inclined lines 46 lead from channel 18 to an annular groove forming an air chamber 47

723078516.11.72

of the conical part A1 of the spindle 51. In the spindle 31 is a tube 17 above the air chimney 47 surrounding seal 48 mounted. From the air chamber 4? lead four channels 49 through the conical part 4l to channels 50 passing through the hub 42. A wedge 51 is located on the surface of the conical part 41 attached, which engages in a keyway of the Kate 42 and ensures that the channels 49 and 50 into one another pass over. A sealing ring 32 is arranged around the pressure tube 17 just below the hub 42.

The hub 42 is part of the head block 53 on which the tools of the head set are mounted. A cap 54 is screwed to the head block which forms the hub 42 surrounds. The head block 53 has four cylinders 55

(see also Fig. 2). Each of the channels 50 leads to a cylinder 55 * wa a piston 56 arranged in this cylinder to be displaced by air pressure. The pistons 56 act directly on frame arms 57, which are connected to the adjusting spindles 58 rotatably mounted in the block 53. Each arm 57 is provided with an adjustable stop 59 which ^{engages part of the block 53 to limit the V. r} C ( ^r es, via which the piston 56 can be moved outwards. Around the spindle 58 there are torsion springs 60 arranged, which act on the arms 57 and ain block 53 and drive the pistons 5δ back into their Innenpositions when the air pressure from the cylinders 55 has dissipated.

Two of the adjusting spindles 58 are connected at their lower ends with G (.winderöl] poor Gl, while the other two adjusting spindles are connected with edge rolling arms G ? . {'.- ,. also Fig. 4). Every win contributes 6 liters of noise

a thread roll 6j5, which is on a in a bearing sleeve

65 rotatable we ^ Ie 64 is attached. The shaft 64 is in arm 6l with a small angle opposite Jer Arranged vertically. The thread roll 63 is relative axially movable to the arm 6l and is made by a compression spring

66 pushed up. The spring 66 is supported on the sleeve 65 and presses against a cb engaging a shoulder 68 of the shaft 64 flange 67. The springs 66 are somewhat _(easy)} so that a relatively freis axial movement of the rollers is possible soft 63rd The rollers can therefore follow the threads of the bottle and the springs only return the rollers to their original position when the arms 62 are retracted.

In the same way, the arms 62 carry edge rollers 69, the shafts 70 which are rotatably mounted in bearing sleeves 71 are connected. The sleeves 71 are, however, mounted vertically in the arms 62. The shafts 70 are axially displaceable and are urged upward by compression springs 72 as previously described. In contrast to the Springs 66, the springs 72 are designed to be relatively strong. They are intended to provide such elasticity that an acceptable inwardly turned locking edge can be obtained there also gets wc vertical inconsistencies regarding the position of the corresponding edge collar on the bottle. It should also be noted be that the vertical position of each bearing sleeve 71 is adjustable in that the bearing sleeve is mounted in a threaded hole in the arm 62.

The position of the bearing sleeve 71 with respect to the arm 62 is determined by means of a; ¹ grub screw 71a fixed. To the

The end of the pressure tube 17 is rin 3chraubgev: inde to Attachment of a lower pressure block 73 provided. Between the pressure block 73 and the head block 53 is a needle bearing 74 and a bearing seal 75 around that End of the pressure tube 17 provided around.

The lower part of the pressure tube 17 has a bore 76, which is slightly larger than channel l8. The plug 45 is snugly seated within the bore "76. It can be seen that the lower pressure block can have many different shapes because of its construction depends on the size and type of closure to be applied. The pressure block 73 is formed so that it deforms the head of the closure and contains a head pressure part 79 which is arranged to slide in the bore 76 is. Between part of the block 73 and the pressure part 79, a compression spring 8c is arranged, which Printing part 79 drives to uni ~ en. In opposite Peiten of the pressure part 79 transverse pins 8l are used, which act in slots 82 of the pressure block 73 in such a way that they restrict the vertical movement of the pressure part 79. A rod 78 is slidable in a bore 76 and a bore passing through the pressure part 79 attached. The rod is engaged by one in the bore 76 between the plug 45 and the top of the rod 78 arranged compression spring 77 driven downwards.

The on the top of the ^inh: acting pressure effect of the pressure part 79 exposed to the closure pressure is transmitted through the lower block 13 * the pressure tube 17 and the lower Druckblcck 73rd The upper pressure b ¹ oc'k 13 is connected to the piston 9, which is constantly in contact with the compressed air with which the cylinder 8

The Auf v.

The application of compressed air to the cylinder 8 is not directly related to the application of pressure to the cylinders of the roll-on arms. Thus, the head of the closure can be deformed before any radial pressure is exerted on the closure rim. Furthermore, in contrast to other systems in which pressure is applied to the head, the pressure of each closure head can be divided from a central "" can be changed, if necessary even while the machine is in operation.

In the present case, the rotation of the head block 53 causes the rollers 63, 69 to rotate around the bottle 3. The rotation of the head set is achieved due to its rigid partial connection on the drive spindle J> \ of the closing head 1. The drive spindle J> 1 is driven by a toothed part J> 2 , on which a drive gear or a belt engages. Both the pressure tube 17 and the drive housing 28 remain stationary. The toothed part J>? extends axially so that it remains in engagement with drive gear 132 (or suitable drive means) while the capping head is vertical.

As FIG. 3 shows, in a multi-head capping machine for containers adjacent closing heads arranged in a circle so that the toothed part 3? of each closing head engages in a drive gear. This arrangement was also made for the case Found useful that the machine is used in a production line.

The air to be introduced into the cylinders 55 is initially introduced through line l6 into the channel l8 of the pressure tube 17. The compressed air arrives from here via a line 46 to the annular chamber 47 in the rotating drive screw 31. Each of the cylinders 55 is via separate Channels 49, 50 connected to the chamber 47 to allow the pistons 56 can be operated simultaneously.

In the line 16 of each closing head is a flexible pipe, which is attached to the turret

brought air control valve comes, air entered. Each air control valve receives air from a stationary center tube through a rotating cap. That Air control valve typically works so that the flexible pipe with compressed air from the central pipe or with can be connected to the atmosphere. Since the sealing heads revolve around the fixed center column, this can Air control valve through another cam control are operated on the support, both the timing and the duration of the air supply to and from Line 16 can be controlled in this way.

In view of what is described under Bc7 \ ignahrr.e on the figures Closing law-iV and head sentence are different Modes f '. <A ^ ions possible. For example, can the head sentence so arranged v; ground that the arms of Edge and / or thread roll stored on a pin

inclined to the vertical. In one possible construction, the pivot pin is horizontal, and the arms swing back and forth in a vertical plane. The rollers can be carried by vertical spindles extending from one end of the arms.

A significant advancement of the device

consists in the separate control of the fluid pressure for the edge rolls and the thread rolls. To this For this purpose, separate channels to the respective cylinders in the head set are required.
