Definitions
- the present invention relates to a method for aligning blanks of packaging, which can be used in particular for aligning labels on cigarette packages, as well as a device used for this purpose and a machine for packaging cigarettes fitted with a such device.
- the packaging blanks are conveyed by batteries to said machine after being removed from a stock, generally from a pallet.
- the published application EP-A-0.354.873 describes a depalletizer of cigarette packet labels supplying a packaging machine. Due to the handling and transfers to which each stack of blanks or labels is subjected before arriving at the packaging machine, it is possible that one or more of the blanks or labels of the stack shifts slightly compared to the rest of the battery. If no precaution is taken to realign the stack before it is inserted into the packaging machine, the roughly aligned label or blank will not generally be accepted by the machine, it may even be folded or even destroyed by jamming, which usually stops the packaging chain.
- a device is also proposed, as described in claims 4 to 10, making it possible to correctly align and orient a stack of blanks or labels.
- a packaging machine capable of correctly aligning and orienting the stacks of blanks or labels which it receives.
- FIG. 1 and 2 there is a portion of a cigarette packaging machine 1, on which is disposed a plate 10 which can take, under the action of the piston 11, an elevated position as shown in Figure 1 or a low position as in FIG. 2.
- Feeding means 12 for example a conveyor belt, bring a stack 2 of labels 20 for cigarette packs from, for example, a depalletizer for cigarette pack labels such as described in application EP-A-0.354.873, on the plate 10 when the latter is in the low position.
- the labels In order to be accepted for the following operations for forming the packet of cigarettes, the labels must be properly aligned, as represented by the bold line corresponding to the label 20 in FIG. 1.
- the main object of the invention is therefore to propose a method and a device making it possible to realign the labels in the stack 2, so that they are all aligned in a determined position, for example that represented by the label 20
- the device according to the invention is composed of a first pivoting portion 3 held by a second portion able to move longitudinally 4.
- the portion able to move longitudinally is mainly composed of two carrying arms 40 and 41, preferably arranged horizontally, and capable of moving longitudinally by a certain distance, in order to approach or move away from each other , under the action of means which will be described later.
- the pivoting portion 3 is mainly composed of two receiving portions in the form of half-shells 30 and 31, each composed of a support wall 30A, respectively 31A, of an upper wall 30B, respectively 31B, of a wall bottom 30C, respectively 31C and an end wall 30D, respectively 31D.
- each half-shell 30, 31 has the general shape of a rectangular parallelipiped of which two walls of each of the half-shells have been removed, those closest and directly facing the stack 2, thus creating a front opening on each half-shell and two side walls, those which would be opposite the walls support 30A and 31A, thus creating lateral openings.
- Each of the half-shells 30, 31 is fixed to a pivoting arm 32, respectively 33, by its end wall 30D or 31D, each of said arms 32.33 being provided with a pivot 34.35, preferably centered on the center of gravity of each of the half-shells 30 and 31 and pivoting in a bearing 42, respectively 43, arranged in each of the carrying arms 40 and 41.
- the other ends of each of the pivoting arms 32, 33 are preferably connected by a device sliding, consisting for example of a rod 36 sliding inside a tube 37 of which at least a portion is calibrated on the diameter of the rod 36.
- One of the two pivots is extends on the other side of the bearing 42 and is connected to a rotational drive means 38, preferably a pneumatic actuator, capable of driving the half-shell 30, via the pivot 34, then the half shell 31 by means of rod 36 and tube 37, in a rotational movement 90 ° sequential as explained below.
- the body of the actuator 38 is fixed to the support arm 40.
- the actuator 38 has been described as being pneumatically controlled, but it may also be a device with hydraulic or electric drive; just as the second half-shell can be driven by its own actuator, synchronized with the first and which would be arranged symmetrically with the actuator 38 shown, and not by means of the rod 36 and the tube 37.
- each of the support arms 40 and 41 can move longitudinally over a portion of the packaging machine 1, the support arms 40, 41 being able to approach or move away from one another. 'a certain distance. For this, they each rest on a slide 44A moving on a slide 44B between two stops 44C and 44D representing the extreme positions of movement, preferably provided with limit switches.
- the slide 44B can also be provided with another detector 44E signaling a half-closed position as explained below.
- a single slide / slide play has been shown in FIG. 1 in order to facilitate reading, it being understood that the support arm 41 is equipped in the same way. As a variant, it is also possible to have only one slide common to the two support arms 40.
- actuation means which can be, for example example a spring 45, tending to bring the two arms 40 and 41 closer together, which exerts its effect in opposition to a pneumatic or hydraulic device consisting of a cylinder body 46A, fixed to the frame of the machine, in which a piston 46B connected circulates by a rod 46C to the support arm 41.
- actuation means which can be, for example example a spring 45, tending to bring the two arms 40 and 41 closer together, which exerts its effect in opposition to a pneumatic or hydraulic device consisting of a cylinder body 46A, fixed to the frame of the machine, in which a piston 46B connected circulates by a rod 46C to the support arm 41.
- D 'other means can be used to bring these movements of approximation / distance of the two support arms, for example the action of the spring 45 and the cylinders 46A, 46B can be opposite to that described, the spring tending to distance the two br as carriers while the jack is arranged to bring them together; another possibility, visible in FIG. 3, is to provide a double-acting pneumatic or hydraulic cylinder 47; it is thus possible to remove the spring. It is also possible to directly motor the slides 44A, by electro-mechanical means or, as seen in FIG. 4, to provide a device 48 for rotating a rod 49, the ends of the latter comprising reverse threads which are screwed in and out respectively in suitable threads provided in the support arms 40 and 41.
- one of the support arms is fixed to a strand of a belt endless while the other carrying arm is fixed to the other strand of the same belt; by applying a movement of displacement to the belt, one obtains a ruzement, respectively a separation of the two carrying arms.
- the support arms 40, 41 respectively the two half-shells 30 and 31, are separated from each other as much as possible; the two half-shells 30 and 31 are turned so that their lateral opening is directed from the side, either upwards according to the representation in FIG. 1 and to the left according to the representation in solid lines in FIG. 2.
- the plate 10 is in the low position, as shown in FIG. 2.
- a stack 2 which may include one or more misaligned labels 21, 22, 23, is brought by supply means, for example a conveyor belt 12, placed at a height such that the stack 2 can pass underneath the half shell 31.
- the conveyor belt 12 stops when the center of the stack 2 has approximately arrived at the center of the plate 10.
- the latter is then raised, by means of the jack 11, so that the lower surface of the label placed at the very bottom of the stack 2 is very slightly above the plane formed by the two lower walls 30C and 31C of the two half-shells 30 and 31.
- These are then brought together, by the means of longitudinal displacement of the support arms 40 and 41 described above, up to an intermediate or semi-closed position, as shown in Figure 3.
- the horizontal axis along which the stack 2 is transported by the conveyor belt 12 is offset laterally relative to the horizontal axis comprising the center of gravity of the half-shells 30 and 31 , corresponding approximately to the axis connecting the two pivots 34 and 35.
- This distance between these two horizontal axes corresponds to the maximum allowable extent of a lateral offset of a label 22 in the stack 2.
- no part of the labels placed in the stack 2 should for the moment come into contact with any of the parts of the half-shells 30 and 31.
- the distance separating the two internal faces of the upper and lower walls 30B and 30C, respectively 31B and 31c is slightly greater than the height of the stack 2.
- the edges of the p support arois 30A and 31A may include a flare 30E, 31E respectively, which facilitates the introduction of a label whose misalignment is very close, or even slightly greater than the maximum allowable misalignment.
- the pivoting portion 3, respectively the two half-shells 30 and 31 containing the stack 2 then pivots 90 °, around its longitudinal horizontal axis, driven by the actuator 38 as explained above, so that the walls of support 30A and 31A come in the lower position, as shown in FIG. 4 or as visible by a broken line in FIG. 2.
- the labels 20, seen from above in FIG. 4 therefore come to support their lower edge, by gravity, on the support walls 30A and 31A. Since there is a lateral clearance between the labels, originating between the difference between the height of the stack 2 and the distance between the upper and lower walls of each half-shell 30, 31, said walls now being arranged laterally with respect to stack 2, this downward movement can be carried out very freely.
- the labels 22, 23 which had a transverse misalignment are now realigned correctly with respect to the stack 2.
- control unit 5 (see FIG. 1) comprising a central unit 50, itself controlled by the general control of the packaging machine, and acting sequentially on the different drives of the device.
- sensors may be available, for example on the stops 44C and 44D, as well as one or more sensors 38A on the actuator 38, as well as a position sensor 44E on the slide 44B.
- the labels 20 have one printed side while the other side is devoid of printing. It is possible that, during the manipulations intervening earlier in the process, some stacks of labels are completely turned over, that is to say that, if for example the stacks should normally appear with the printed side of the labels facing the high to be properly processed by the cigarette packer, a stack may present from time to time with the label side facing down.
- a detector device 6 preferably composed of a transmitter 60 and a receiver 61, preferably arranged in the same housing (see Figures 1 and 2).
- the transmitter 60 will preferably be a transmitter of light radiation, directed towards the battery 2, the receiver 61 being adapted; the light ray which has been emitted by the emitter 60 and then reflected by a surface of the label arranged nearby to return to the detector 61 will have a different intensity depending on whether said surface is printed or white.
- This signal is then sent to the central control unit 50 which, when the labels 20 have all been aligned as described above, will control the pivoting of the pivoting portion 3 according to the intensity of the signal received, ie for a return to its initial position, in case the stack is correctly oriented, or for an additional pivoting of 90 ° in order to present it in an inverted position of that according to which the stack 2 was presented at the entrance of the device, so that the stack 2 is oriented properly for the further processing of the labels.
- the alignment device has been described according to a preferred embodiment, but it is obvious that other modes of construction can be envisaged; in particular, it is not necessary for the carrying arms 40 and 41 to be horizontal, they can also be arranged obliquely or then vertically. A person skilled in the art will know how to design the slides and slides 44A and 44B so that the device does not tip over. It is also not absolutely necessary that the walls of the half-shells are full as shown in the figures, they can also be perforated.
- the means of transporting the batteries have been described as consisting in particular of two conveyor belts bringing, respectively discharging, the stacks of labels.
- the method and the device according to the invention make it possible to easily reach the set goals, that is to quickly and efficiently realign drafts or misaligned labels as well as to reorient a misaligned stack.
- Another advantage of the device is that, given its relatively simple design and small footprint, it is entirely possible to integrate it on an existing packaging machine in order to considerably improve its performance by reducing downtime. due to stuck label.
