Abstract

A gas cylinder (10) with a valve (11) is positioned by an actuator (110) and a label (20e) is carried by a positioning head (350) axially aligned with the cylinder and lowered to be fixed as a collar around the valve (11). A feeding device (300) allows a single label to be removed from a batch (311) and positioned (20d) on a pan (340) to allow it to be picked up by the head (350) movable from its cylinder-aligned position. Advantageously, the apparatus further comprises a fixing tool (450) ensuring that a cap (30a) is placed on the valve 11 of the cylinder (10) which was previously centred by the head (350). Movement of the fixing tool (450) to cylinder-alignment occurs with movement of the head (350) to pick up a label (20e).. The head has a conical bore for surrounding the valve (11) and holds the label by suction. <IMAGE>

Description

SPECIFICATION Apparatus for positioning a label on a gas cylinder containing a liquefied petroleum gas in particular a combined label-positioning and cap-fixing apparatus The invention relates to an apparatus for positioning a label on a gas cylinder, in particular a cylinder containing a liquefied petroleum gas such as butane or propane.
The label that will be referred to in the description and the claims is a collar-shaped label placed around a valve located at the top of the cylinder. This type of label is represented in particular in figure 1, wherein reference number 10 designates a cylinder provided at its upper part with a valve 11; the label 20 is, for example, in the shape of a disk with a central aperture 21 enabling it to be placed around the valve 11 (indentations 22 allow this operation to be performed without tearing the label 20). The label 20 is positioned so that its printed side, bearing various texts about safety rules to be observed when the cylinder is used, faces upwards so as to be immediately apparent to the user.
It will likewise be seen that the apparatus allows, as a secondary function, the cylinder to be capped after the label has been positioned, i.e., a cap such as that referenced with the number 30 in figure 1 to be fixed to the top of the valve 11. Said cap 30 constitutes a commercial guarantee indicator and further ensures leaktight sealing of the valve 11 in case the closure element of said valve allows slight leakage. In addition, it will be noted that placement of the cap prevents any subsequent accidental or non-accidental removal of the label placed around the valve beforehand.
One of the difficulties encountered both when a label is positioned and when a cap is fixed lies in the perfect centring that has to be ensured between the axis of the valve and the axis of a head bearing the label to be positioned or of a fixing tool.
In fact, poor centring will cause the label to be torn and makes it impossible to apply the cap correctly and tightly.
It has furthermore been found that the centring operation that is essential for achieving a satisfactory result is very exacting in terms of operating speed. Label positioning and cap fixing are, in fact, accomplished at the end of automatic filling lines which can attain speeds of, for example, 800 cylinders per hour. The invention proposes an apparatus allowing label positioning to be accomplished fully automatically and compatibly with the requirements of said speeds.
To this end, the apparatus according to the invention comprises: a label positioning head able to move axially between a high position and a low position where it encircles the valve and places the label around it; means for centring the cylinder so as to align the axis of the label positioning head and the axis of the valve; and label feeding means suitable for removing a single label from a batch and placing it underneath the label positioning head located at the high position coaxially with the label positioning head.
The part of the label positioning head encircling the valve is advantageously shaped as an orifice flared in the downward direction, of which the narrow part has a diameter close to the outer diameter of the valve so as form a centring means when the label positioning head is lowered, the centring of the cylinder and the placing of the label around the valve thus being accomplished simultaneously.
In that case, cylinder vibrating means operated while the label positioning head is being lowered are preferably provided as well in order to assist the centring of the axis of the valve on the axis of the label positioning head.
According to an advantageous embodiment, the label positioning apparatus is equally suitable for capping the cylinder.
To that end, it further comprises: a fixing tool able to move axially between a high position and a low position where it places and fixes a cap on the valve, the axis of the fixing tool and the axis of the valve having been prealigned; and cap feeding means suitable for removing from a batch a single cap and placing it underneath the fixing tool located at the high position.
In that case, the cap feeding means preferably comprise a cap pick-up element and means for loading the fixing tool with the cap present on said cap pick-up element. The fixing tool is able to move in the transverse direction simultaneously with the label positioning head, the fixing tool and the label positioning head being arranged such that, when the label positioning head is lowered, the fixing tool is lined up with the cap pick-up element so as to accomplish simultaneously the positioning of the label and the loading of the fixing tool with the cap destined for that cylinder.
Equally preferably, the label feeding means comprise a label pick-up element and means for loading the label positioning head with the label present on said label pick-up element, and the fixing tool is able to move in the transverse direction simultaneously with the label positioning head, the fixing tool and the label positioning head being arranged so that, when the fixing tool is lowered, the label positioning head is lined up with the label pick-up element so as to accomplish simultaneously the fixing of the cap and the loading of the label positioning head with the label destined for the next cylinder.
The simultaneous timing of the various operations (cylinder centring, label positioning and cap pick-up on the one hand, cap fixing on precentred cylinder and pick-up of next label on the other) makes it possible to attain the high operating speeds, imposed by presentday filling lines, with the help of a single fully automated installation for the accomplishment of the hereinabove indicated operations.
Other characteristics and advantages of the invention will become evident from perusal of the detailed description hereinbelow, in which reference is made to the appended drawings wherein: the aforesaid figure 1 schematizes in perspective the top of the cylinder receiving a label and cap; figure 2 is a schematic general view in perspective of the label positioning and cap fixing apparatus according to the invention; figure 3 is a magnified view of the detail referenced ill in figure 2; and figure 4 is a sectional view of the label positioning head corresponding to the detail referenced IV in figure 2.
In figure 2, the cylinder 10, which follows the general direction aa of the conveyor, is shown at the moment when it has been halted in the label positioning and capping apparatus by means of a stopping and precentring device 100.
Said device 100 comprises an actuator 110, operated by a sensor (not shown) and bearing at the extremity of its rod 120 a stop 130 against which the cylinder 10 comes to rest.
Said actuator 110 accomplishes a precentring of the cylinder 10, i.e. any misalignment between the axis of the valve 11 and the axis of a label positioning head 350 surmounting it is kept within a predetermined limit which can be corrected by the centring means described hereinbelow.
The cylinder 10 in this position is supported by an assembly 200 comprising a receiving element 210 that can be raised and/or lowered by actuator 220. In addition the cylinder 10 can be vibrated with the use of vibrator 230.
Furthermore, the label positioning head 350 (shown in detail in figure 4) has at its lower part a flared orifice 351 with, for example, a conical surface 352 of which the upper part 353 has a diameter close to the outer diameter of a cylinder valve 11.
Precise centring of the cylinder 10 is effected in the following manner: under the combined effect of the actuator 220 raising the receiving element 210 and of the actuator 356 lowering the label positioning head 350, said label positioning head 350 approaches the valve 11 that it is to encircle. The contacting action of the valve 11 against the conical surface 352 produces a transverse displacement of the cylinder 10, causing it to be recentred in relation to the axis of the label positioning head 350. The vibrator 230, operated during this centring phase, allows the horizontal component of the frictional force of the cylinder 10 on the receiving element 210 to be virtually eliminated, so that the force to be applied to the valve 11 in order to centre the whole cylinder 10 is always very low.
Label positioning is effected simultaneously with this centring operation: to that end, before the label positioning head 350 is lowered, means (which will be described hereinbelow) place underneath said label positioning head 350 a label 20 in the position referenced 20e in figure 4 (the central aperture 21 of the disk-shaped label 20 being coaxial with the axis of the label positioning head 350).
Said label 20 is held in place by suction, by gripping means in the form of suction orifices 354 terminating at the inner periphery of the label positioning head 350 and connected by ducts 355 to a vacuum pump (not shown) operated selectively according to whether the label 20 is to be picked up and held underneath the label positioning head 350 (during the positioning operation) or released (on completion of positioning).
Advantageously, the suction orifices 354 are provided with flexible bellows 357, which enable the label positioning head 350 to operate correctly even in the event of a shock impact against the cylinder 10 and makes it possible for the label to be displaced transversely without tearing during centring.
Label feeding means 300 will now be described; said means allows a single label to be taken from a batch and positioned underneath the label positioning head 350 at high position coaxially with said head 350 (i.e. in the position referenced 20e in figures 1 and 4).
An assembly 310 allows the labels to be stored in a stack 311 in a very gently inclined chute 312, with a mass 313 exerting a slight pressure on the stack and allowing it to advance as the single labels are removed one by one. A vibrating device 314 allows the stack to be vibrated during label removal to ensure that one label only is picked up at a time.
Label removal is effected by an assembly 320, shown in detail in figure 3: it comprises an actuator 321 furnished with an orientable suction head 322 at the extremity of its piston rod 323. Said suction head 322 can be oriented by external actions (it is, for example, in the form of a bellows-like suction cap of very pliable elastomeric material (not shown)), and the axis of the piston rod 323 is oriented obliquely in relation both to the first exposed label 20a on the stack 311 and to the plane of a ramp 330 down which the removed label is to slide in the direction of the label positioning head 350.
Operation of said assembly proceeds as follows: the piston rod 323 is extended (position shown in figure 2) so that the suction head 322 adheres to the first label 20a of the stack 311 (where the label is kept in place, for example by peripheral stops such as 315). In this position the orientable suction head 322 is slightly bend. The piston rod 323 is then retracted (position shown in figure 3), the effect of which is to cause the label to turn slightly (position 20b, perpendicular to the axis of the piston rod 323) as a result of the orientable suction head 322 returning to its initial position (the suction head 322 having been deformed and oriented obliquely by contacting the label 20a).Suction is then interrupted, which causes the label 20b to be released and pass, under its own weight, to position 20c at the top of the ramp 330, down which it continues to slide as far as a label pick-up element in the form of label pick-up pan 340 (figure 2), coming to rest (in position 20b) against stops 341.
The label feeding device so designed allows one single label only to be brought onto the label pick-up pan 340, always with its printed side uppermost. Furthermore, the feature whereby the actuator 321 is provided with an orientable suction head 322 and whereby the piston rod 323 of the actuator 321 is obliquely oriented allows the label to be taken up with a very simple motion, requiring a single linear translation movement of an actuator 321 to produce the desired result.
To collect the label, the label positioning head 350 is born by a carriage 500 translata ble along two rails 510 by the action of a linear actuator 520. The label positioning head 350 moves between two positions in which it is either lined up with the valve 11 (as shown in the figure) or lined up with the label pick-up pan 340. At the latter moment, an actuator 342 detaches the label from the pan 340 and presses it against the lower face of the label positioning head 350 where it is held in place by means of suction as described hereinabove.
A label positioning apparatus constructed in accordance with this teaching allows an operating speed of more than 800 cylinders per hour, for a cylinder conveying speed of 20 m per minute, to be attained without difficulty.
The capping device 400, which may be used to supplement the label positioning apparatus described hereinabove, will now be described.
The caps that may be used are, for example, those described in French patent specification No. 2,197,781 in the name of the applicant. A cap 30, as shown schemati cally in figure 1, comprises in the lower part a plurality of fingers 31 encircling the top of the valve 11. A fixing ring 32, lowered by a socket pertaining to a fixing tool, presses the fingers 31 against the valve 11 to complete the capping operation.
Said caps are stored loose in a hopper 410 from which they are passed to a vibrating drum 420 which aligns and arranges them along a feeding ramp 430 as far as a cap pick-up element in the form of cap pick-up pan 440 (cap position referenced 30a). Fixing tool 450, which is likewise borne by the carriage 500, comprises a rod 451 which fits into the central orifice 33 (figure 1) of the cap 30, thereby ensuring that it is gripped. This fitting action is accomplished by operation of actuator 441 which raises the cap pick-up pan 440 so that the cap 30a fits onto the tip of the rod 451.
The carriage 500 is then translated so that the fixing tool 450 is lined up with the valve 11 of the cylinder 10, which cylinder 10 has already been centred by the prior lowering of the label positioning head 350.
The socket 452 of the fixing tool 450 is then lowered by the actuator 453, the effect of which is to apply the cap 30 against the valve 11 and to irreversibly press the ring 32 into the position where the fingers 31 are pressed against the valve 11, corresponding to complete fixing (position referenced 32a in figure 1).
It is highly advantageous for the axis of the valve 11 (after centring) to be situated exactly halfway between the label pick-up pan 340 and the cap pick-up pan 440. Thus, it is only necessary to provide two operating positions for the carriage 500: one position (that represented in figure 1) in which the label positioning head 350 is lined up with the valve 11 and the fixing tool 450 is lined up with the cap pick-up pan 440, and one position in which the label positioning head 350 is lined up with the label pick-up pan 340 and the fixing tool 450 is lined up with the valve 11.
Thus, the operating phases of the label positioning and capping installation according to the invention are as follows: halting and precentring of the cylinder 10 on striking the head 130 of the actuator 110; from the standby position represented in figure 1, descent of the label positioning head 350 preloaded with a label and lifting of the cylinder 10 which is made to vibrate, the label positioning head 350 then encircles the valve 11, centres the cylinder 10 and releases the label, and simultaneously the fixing tool 450 picks up the cap 30a present on the cap pickup pan 440; re-raising of the head 350 then translation of the carriage 500; ; positioning and fixing of the cap 30 by the fixing tool 450 which is then lined up with the valve 11 (the cylinder 10 remaining centred) and simultaneously, gripping of the label 20d for the next cylinder by the label positioning head 350 which is then lined up with the label pick-up pan 340; re-raising of the fixing tool 450; and releasing the cylinder 10, returning the carriage 500 to its standby position and admitting a new cylinder.
