Description

Technical field

The present invention relates to a labeling device.

The present invention relates to a manually controlled labeling device for applying labels bearing one or more labels, for example, indications of products on which said labels are applied, or product prices.

Specifically, the present invention is suitable for use in storages and / or in any trading activity, for example in department stores, supermarkets, stores and / or the like, in which there is a need to attach various types of trade and / or information symbols.

State of the art

As is well known, there are manual-controlled labeling devices that include a supporting structure within which a device for supplying a label-holder tape is provided. The label holder tape is appropriately guided within the supporting structure to the labeling area, where each label carried by the tape is detached from it for attachment to the corresponding surface of the package or product.

In order to enable the label holder tape to advance inside the supporting structure, known labeling devices are provided with an appropriate actuator that pulls the tape to a position beyond the application area, forcing it to advance toward the tape output area without labels.

Said labeling devices are also provided with a device for stopping and / or braking the tape to ensure that each label is applied without unwanted stretching of the tape. Specifically, known labeling devices comprise, between the tape supply device and the labeling area, a number of mechanisms that continuously press the label-holder tape to an adjacent surface inside the supporting structure. Thus, when the label, which has been partially detached from the label-holder tape, is positioned on the intended surface by the combined action of pressure towards the indicated surface and the labeling device is translationally moved on it, the label-holder tape is kept in a fixed position, allowing complete detachment labels to be applied. Known labeling devices further comprise a control device, usually represented by a movable element, which has a corresponding gripping device operatively connected to the driving device to deliver labels transferred by the tape to the application area in a sequential order to each other. Specifically, when the control device is manually driven, the interaction between the last and the actuator actively drives the label-holder tape, which, overcoming the blocking forces exerted by the locking device, advances as described above.

A printing element is also provided inside the structure, capable of placing on each label, in front of the application area, a predetermined amount of ink in accordance with predetermined patterns, whereby the above-mentioned trade and / or information symbols are obtained.

Despite the fact that the known labeling devices provide the ability to print and satisfactorily label the packaging and / or surface of the products, the applicant noted that they have some drawbacks, mainly in relation to the operation and wear of the locking device, the replacement and / or maintenance of one or more constituent elements of the printing device, as well as wear labels and / or tape-holder labels.

Specifically, it was noticed that the constant and continuous pressing of the label-holder tape by the locking device to the corresponding adjacent surface causes, in the end, significant problems with the calibration of the components of this device, as well as excessive wear of the mechanical parts associated with friction or rotation, requiring constant interventions to service and / or replace one or more components of the locking device.

This problem also affects the general conditions of the label-holder tape and the labels themselves, the structure of which may be impaired, presenting an aesthetically unpresentable appearance and / or, even worse, an inadequate print surface on which the used ink is placed inaccurately, leading to the occurrence of unwanted defects.

It should also be noted that both the difficulty in accessing the internal areas of the supporting structure of the known labeling devices, and the difficulty in replacing some commonly provided constituent elements of the printing device, such as a paint roller, etc., entail intensive maintenance, requiring at the same time, a substantial qualification of the service operator, who must, with special tools and devices, gain access to the colorful roller in order to remove it from the structure and replace Wear it with another colorful roller.

Disclosure of invention

Therefore, the main objective of the present invention is to overcome the disadvantages of the prior art.

Specifically, an object of the present invention is to provide a labeling device provided with a self-regulating braking system, i.e. able to control the clamping of the tape to the corresponding adjacent surface in accordance with the advancement or stop of the tape.

An additional objective of the present invention is to provide a labeling device, which is easy and simple to carry out the replacement of the constituent elements of the printing device.

Description of Illustrative Embodiment

With reference to the attached figures, reference numeral 1 denotes a labeling device as a whole, in accordance with the present invention.

As shown in FIGS. 1 and 2, the labeling device 1 comprises a substantially enclosed structure 2 representing the handle 3, preferably obtained by two-component molding with a rubber sheath 2b, located at the back for manually capturing the labeling device.

Inside the structure 2, essentially in the central region, there is provided an element 4 for supplying a tape 5 provided with a plurality of labels 6 (one of which is shown schematically in FIG. 1), intended for printing on them and fixing on the outer surface of the respective packages, labels and / or products.

As shown in FIGS. 1 and 2, the feed member 4 preferably comprises a feed coil 7 pivotally coupled to the structure 2, rotatably about a corresponding rotation axis “X”.

Advantageously, the feed coil 7 is removably mounted in the structure 2 so that it can be removed from it when the feed coil 7 is completely used up.

As shown in FIG. 2, the feed spool 7 can advantageously be inserted or removed through the corresponding access hole 8, located in the lower part of the structure, and properly maintained closed by additional components of the labeling device, which will be described later.

In order to guide the tape 5 between at least the supply element 4 and the application area 9 of the at least one label 6, the structure 2 is provided with a corresponding guide means which restricts, in accordance with a predetermined route, the path of advancement of said tape 5.

As shown in FIG. 1, the guide means leads the tape 5 from the feed member 5 to the application area 9, which is preferably located lower with respect to the structure 2 of the labeling device 1, close to its front portion 10. The labeling device further comprises at least a device 11 for driving the tape 5, functionally located inside the structure 2. The driving device 11 has the ability to move between an idle state in which the tape 5 does not move, remaining at a predetermined position, and the operating state in which the driving device 11 causes the tape 5 to move along a path limited by the guiding means to deliver at least one label 6 of the tape 5 to the application area 9.

As also shown in figures 1 and 2, the labeling device further comprises an element 12 for stopping the tape 5, functionally located inside the structure 2. The locking element 12 has the ability to move between the stop state in which it prevents the tape 5 from being driven, pressing the latter against an adjacent surface 13 associated with the structure itself and a release state in which the pressing of the tape 5 against the adjacent surface 13 is reduced in accordance with a value such that the tape 5 is released so that move in advance the way mentioned above.

In order to control both the driving device 11 and the locking element 12, the labeling device comprises at least one control device 14 operatively associated with the structure 2, preferably lower with respect to the handle 3. The control device 14 is functionally attached to the locking element 12 and to the driving device 11, in order to deliver at least one label 6 located on the ribbon 5 to the application area 9.

More specifically, the control device 14 comprises a control handle 15 pivotally attached to the structure 2 of the labeling device 1 in its rear region to move it back and forth around the corresponding rotation axis “Y”. The control handle 15 has, with respect to the handle 3, a grip portion 16 having an ergonomic shape to facilitate and facilitate its grip by hand. The control handle 15 is constructed in a conventional manner inside the structure 2, representing the first control unit 17 located close to the locking element 17, and the second control unit 18 located close to the driving device 11.

Advantageously, at least one opposing resilient member 19, preferably a coil spring 19a, is operatively inserted between the grip portion of the control device 14 and the handle 3 of the structure 2 to maintain the latter in a predetermined position.

Advantageously, the control device 14 can be moved between the first position in which the locking element 12 is in the locking state and the driving device 11 is in the idle state (FIG. 1) and the second position in which the locking element 12 is in the released state , and the driving device 11 is in working condition, i.e. in a state of application of a pulling force to the tape 5, which allows you to unwind the corresponding feed coil 7.

In more detail, the movement of the control device 14 from the first to the second position occurs by hand squeezing the grip portion 16 of the control handle 15, which, therefore, rotates counterclockwise around the rotation axis “Y”. The capture portion 16 approaches the handle 3, compressing the coil spring 19a, and the corresponding control units 17, 19 are moved, determining a state change with respect to the locking element 12, which reduces its load on the tape 5 and the driving device 11, which drives tape 5 along the way.

And vice versa, if the action is interrupted manually as the capture section 16 approaches the handle 3, the control device 14 tends to return to its original position, i.e. completely move away from the handle 3, turning clockwise around the axis of rotation "Y".

As shown in FIGS. 1-5, and specifically in FIGS. 3-5, the above-mentioned locking device 12 comprises, in detail, a first element 20, preferably made of plastic material, pivotally connected to the structure 2 by a pivot rod 21, which defines the corresponding axis of rotation "Z", essentially parallel to the axis of rotation of "X" and "Y", respectively, of the feed coil 7 and the handle 15 of the control. On the opposite side from the hinge rod 21, the first element 20 has a small interacting part 22, preferably a metal one, installed mainly by two-component molding in the corresponding socket 23. The interacting disk 22 is functionally connected to the first control unit 17 of the control device 14 so that it moves between the first and the second state causes the locking device 12 to be moved between the locking state and the released state.

As also shown in FIGS. 3-5, the locking element 12 comprises a second element 24, preferably a metal element, articulated to the structure 2 by means of the articulated rod 21 rotatably about the axis of rotation "Z". Advantageously, the second element 24 has an inclined portion 25 that interacts with the tape 5 to block it against the abutting surface 13 when the locking device 12 is in the locking state, and to allow the tape to advance along the advancement path when the locking device 12 is in released state.

The locking element 12 contains at least one elastic connecting element 26, placed between the first and second elements 20, 24, to connect the latter and at the same time to allow relative rotation around the axis of rotation "Z". The interaction between the elastic connecting element 26, the first and second elements 20, 24, the control device 14 and the tape 5 on the adjacent surface 13 determines, in a stopped state, the traction force of the elastic connecting link 26 on the second element 24 with respect to the adjacent surface 13. In other words when the control device 14 is in the first position, the first block 17 of the control handle 15 pushes the interacting disk 22 of the first element 20 of the locking link 12 up under the action of the counter spring 19a. In practice, the first control unit 17 of the control handle 15 has a shaped screw 17a, the shaped head 17b of which is in direct contact with the interacting disk 22 located at the end of the first element 20 of the locking link 12 opposite to the second element 24.

Being fixed on the hinge 21, the first element 20 tends to rotate counterclockwise (FIGS. 1-3 and 5), stretching the elastic element 26, which causes the second element 24 to rotate around the "Z" axis and counterclockwise. The rotation of the second element 24, however, is prevented by the opposing surface 13, transforming it into a traction force equal to the force exerted by the elastic element 26 on the second element 24 and on the opposing surface 13. Naturally, pressing the tape 5 against the opposing surface 13 causes it to block.

Conversely, if the control device 14 moves from the first position to the second, the first control unit 17 of the control handle 15 no longer presses on the metal disk 22, allowing the elastic element 26 to remove the load, releasing the tape 5, which can thus smoothly move.

As also shown in FIGS. 3-5, the locking device 12 comprises two elastic members 26, preferably tension springs 26a, functionally interposed between the respective attachment portion 20a of the first member 20 and the corresponding engaging portion 24a of the second member 24 adjacent to each other.

The locking device 12 further comprises an auxiliary resilient element 27, preferably a torsion spring 27a, functionally placed between the adjacent portion 20b (FIG. 4) of the first element 20 and the adjacent surface 24b (FIG. 5) of the second element 24, oriented essentially opposite to the adjacent surface 13. The auxiliary elastic element 27 interacts with the elastic elements 26 to enhance the pulling action of the second element 24 relative to the opposing surface 13 when the locking device GUT 12 is in the locking state and ensure the tension belt 5, when the controller 14 is in the second position, so as to achieve the correct labels detaching from the tape 9 in application.

As shown in FIGS. 1, 2 and, in particular, in FIGS. 7 and 8, the driving device 11 comprises at least one drive roller 28 pivotally mounted in the structure 2 along the path of advancement of said tape 5 and behind labeling area 9 6. The drive roller 28 partially limits the advancement path of the tape 5 and can be rotated in accordance with a predetermined rotation angle to advance the tape 5 in accordance with the corresponding predetermined advancement rate.

The drive roller 28 is advantageously connected to the control device 14 so that it is rotated about the corresponding axis of rotation "W", essentially parallel to the axis of rotation "X", "Y" and "Z" when the locking element 12 is in the released state.

According to a more detailed description of the design of the driving device 11, the drive roller 28 has a plurality of drive protruding parts 29 located on its both flat side surfaces 28a, which are functionally engaged by the driving element 30 inserted between the drive roller 28 and the second control unit 18 of the handle 15 the control of the control device 14. The driving element 30, under the action of the control device 14, acts in a sequential order on each driven protruding part 29 to rotate the drive roller 28 with a constant pitch around the corresponding axis of rotation "W" clockwise and in accordance with a given angle of rotation.

In more detail, the driving element 30 is preferably formed by a latch 31 pivotally attached at its ends to the structure 2 between the drive roller 28 and the grip portion 16 of the control device 14.

When the control device 14 moves from the second to the first position under the action of the spring 19a, the latch 31 engages the protruding protruding parts 29 of the drive roller 28, obtaining its stepwise rotation around the axis "W".

In order to prevent any reverse rotation of the drive roller 28 during the movement of the control device 14 from the first to the second position, the drive roller 28 is provided with a plurality of locking protruding portions 32 (Fig. 8), functionally engaged by means of corresponding locking elements 33. Specifically, the locking the protruding parts 32 are located around the circumference inside the drive roller 28, and they are accessible through two annular recesses 34. The locking elements 33 comprise a single-sided snap fur edited, provided with two resilient tongues, which act on the profile 32 of the locking protrusions.

On a cylindrical surface on the sides of the central annular recess 35, the drive roller 28 has a series of recesses 36 capable of engaging within respective sections (not shown) present on the belt 5.

Toward the periphery of the cylindrical surface of the drive roller 28, an arcuate elastic guide device 37 is provided that is removably attached at its ends to the structure 2 and is capable of holding the tape 5 pressed on the drive roller 28.

Specifically, the resilient tape guiding device 37 has a first end 37a pivotally attached to the structure 2 by two pins 37b, and a second end 37c pivotally attached to the structure 2 by a rod 37d that engages inside the corresponding hinge holes 37e available on the structure itself tape guiding device. The tape guiding device 37 is advantageously made elastic by means of two plate sections 37f, which can rotate, since they are pivotally mounted on the shaft 37d through the hole 37e, thereby ensuring a fixed and phased movement of the tape 5.

As shown in FIG. 2, both the abutting surface 13 and the driving device 11 are supported by a section 2a of the structure 2 that can rotate around the pivot axis "K" coinciding with the axis of the pivot mounting of the driving element 30. The offset of section 2a of the structure 2 as shown in FIG. 2, restricts the aforementioned access hole 8 for inserting and / or removing the reel 7 for feeding the tape 5.

As, in addition, shown in FIGS. 1 and 2, and in particular in FIG. 6, the labeling device 1 comprises a printing device 38 operably connected to the structure 2 in order to apply a predetermined amount of ink to at least one label 6 according to the given pattern.

Advantageously, the printing element 38 comprises at least one supporting element or a supporting arm 39 operably connected to the structure 2 and having a free end 40, preferably provided with two supporting projecting parts 41. The printing element 38 further comprises at least one colorful roller 42, removably attached to the support element 39 between the supporting protruding parts 41.

As can be seen in FIGS. 1 and 2, the printing element 38 is also provided with means for supplying ink 43 to be supplied to the ink roller 42, which is only mentioned here because it does not represent the subject of the present invention.

Advantageously, the printing element 38 comprises at least one mounting device 44 (FIG. 6), which can be functionally placed between the supporting element 39 and the colorful roller 42 to enable its removable connection, together with the colorful roller 42, to the supporting element 39 In other words, the mounting device 44 provides the ability to install or remove the ink roller 42 from the support member 39 without contacting the cylindrical surface of the ink roller 42.
