Description

[Detailed Description of the Invention] <Industrial Application Field> The disclosed technology belongs to the technical field of automatically attaching labels indicating weight, unit price, price, etc. to package trays and the like arranged in display cases of supermarkets.

<Summary of the gist> In this invention, before printing, a large number of labels displaying predetermined items are successively attached to a backing paper of a long sheet in a removable manner and wound around a feeding reel. After printing, the label is peeled and separated from the backing paper using a peeling metal fitting, only the backing paper is wound up on a take-up reel, and the label is adsorbed to a suction bracket by the suction air from the suction/discharge duct of the pasting device installed in front of the peeling metal fitting. This invention relates to a display label suction adhesion device that uses the pressure of exhaust air to blow and adhere display labels to predetermined positions on objects to be adhered, such as package trays, etc., which are coming down below. A suction/discharge bracket that is moved back by an advance/retreat device via an electrically connected control device when most of the label peeled off from the backing paper is adsorbed and the rear end is attached to the backing paper and almost peeled off. This invention relates to a display label suction sticking device in which the display label is forcibly peeled off using a peeling fitting.

<Prior art> As is well known, in distribution departments such as supermarkets, products are displayed in a wide variety of products and in large quantities. In many cases, a label with the date etc. is pasted on it.

Recently, when products such as meat and fillets are packaged onto objects such as styrofoam packaging trays, weight calculations are performed, and the unit price is written on the label.
An automated processing technology has been devised and put into practical use that displays weight, etc., and then pastes it.

Usually, an automatic label pasting device operates synchronously with the product packaging line, and as shown schematically in FIG. The label 2 is continuously attached to each individual piece through an adhesive in a removable manner and wound around the feed reel 3, and the label 2 is peeled off via the peeling fitting 4 through its rigidity, and the mount is attached to the take-up reel 5. 1 is wound up, and the weight, unit price, price, etc. are printed on the label 2 by a printing machine 6 just before the peeling fitting 4, and after being peeled off by the peeling fitting 4, it is pulled by the suction wind of the pasting device 7. It is attracted to the suction/discharge bracket of the suction/discharge duct and waits until the object 8 to be pasted, such as a package tray, arrives directly below it. It is made to be pasted and adhered to the set position on the packaging sheet.

<Problems to be solved by the invention> By the way, as shown in FIG. Although the label 2 is adsorbed at the position, since the winding of the backing paper 1 is an intermittent winding operation that operates in synchronization with the pasting of the label 2 to the package tray 8, the label 2
When the label 2 is attracted and stopped at the position of the suction/discharge bracket 10, the winding of the backing paper 1 is also stopped, so the rear end of the label 2 is attached to the backing paper 1, albeit slightly. Become.

Therefore, label 2 of this suction posture maintenance state
When the object 8 to be affixed, such as a package tray, arrives and is positioned directly below, the discharge air 9 is made to act on the label 2 by switching the damper, but as described above, the rear end of the label 2 Since the base is attached to the mount 1 and is in a connected state, it cannot be completely separated by exhaust air pressure alone, and the turning moment acts, causing it to stick to the mount 1 again and descend to the object 8 to be attached, such as a package tray. The drawback was that there was a possibility that it would not be possible.

In particular, there was a problem in which the probability of this occurring increased when the exhaust wind pressure was unexpectedly weak.

To deal with this, a method has been devised in which a conveyor is placed in front of the peeling fitting 4 at a predetermined position and the peeled label is transferred to the suction/discharge bracket, but since the conveyor rotates below the suction/discharge bracket, In addition to the inconvenience that the label adhesive is attached to the conveyor, there is also the problem that the mechanism is complicated.

In addition, there is a disadvantage that variations occur in the adhesion position, resulting in poor appearance and potentially affecting the commercial value.

<Purpose of the invention> The purpose of this invention is to solve the problems of display label suction and pasting based on the above-mentioned conventional technology as a technical problem, and to securely remove the label from the mount by slightly moving one suction/discharge bracket itself. It is an object of the present invention to provide an excellent display label suction/sticking device that can be peeled off and pasted at a set position, thereby benefiting the field of printing technology utilization in the distribution industry.

<Means/effects for solving the problems> In order to solve the above-mentioned problems, the structure of this invention, which is based on the above-mentioned claims for utility model registration, is wound around a feeding reel in accordance with the above-mentioned purpose. The sheet is fed by a drive roller, the backing paper is wound up by a take-up reel, the label is releasably attached to the backing paper, the predetermined display content is printed by a printing machine, and the label is peeled off from the backing paper using a peeling tool and stuck. The label is sent out against the suction/discharge bracket of the device, and at this time, negative pressure is applied to the suction/discharge bracket by suction air due to the damper setting of the blower of the pasting device. At the timing when most of the bracket is peeled off from the backing paper and the rear end is slightly attached to the backing paper, an advancing/retracting device provided on the frame of the pasting device is actuated by an electrically connected control device to move the suction/discharge bracket forward a predetermined distance. , therefore,
The adsorbed label is moved forward while maintaining the suction posture, and as a result, the rear base end of the label, which was slightly attached to the backing paper, is surely peeled off from the backing paper, and in this state, it waits for the arrival of the object to be stuck. Then, in synchronization with the arrival of the object, the damper switches from the air suction position to the air exhaust position, and the blower's exhaust air applies a downward force to the label on the suction/exhaust bracket, causing it to stick to the object, where it is attached. The suction/exhaust bracket takes technical measures to allow it to return to its original position.

<Embodiment - Configuration> Next, one embodiment of this invention will be described as follows based on the drawings from FIG. 3 onwards. Note that the same parts as in FIGS. 1 and 2 will be described using the same reference numerals.

Reference numeral 12 denotes a display label suction sticking device which constitutes the gist of this invention, and its frame 13 is provided with a reel device 14, a printing machine 6, and a sticking device 7 from the rear to the front.

In the reel device 14, in the case of the feeding reel 3, the take-up reel 5 is provided above and below, and the mount 1
A long sheet 15 on which labels 2 of a predetermined size are successively and releasably attached to each individual piece through an adhesive is wound around a feed reel 3, and is fed by the rotation of a drive roller 32, so that only the mount 1 is attached. is wound onto a take-up reel 5.

During this time, guide pulleys 16, 16..., tension pulley 17, and drive roller 32 are interposed.

Further, at the bottom of the printing machine 6 and immediately before the lower end of the pasting device 7, a peeling metal fitting 4 is installed with the upper end tilted forward, and peels off the label 2 of the sheet 15 by utilizing the difference in hardness with the backing paper 1. It also has a function that allows it to be advanced and fed out.

Incidentally, the printing machine 6 is of a conventionally well-known type.

A blower 20 driven by a motor 19 is provided on one side of the casing 18 of the pasting device 7, and switching dampers 22, 22 are connected to a link mechanism provided on a solenoid 21 provided on the other side. ′
As shown in FIGS. 4 and 5 (FIGS. 4 and 5 are mechanical diagrams for convenience of illustration), the suction port 2 of the blower 20
3 and the ventilation passage in the casing 18 of the discharge port 24 are detected by the control device 2 using an appropriate photoelectric detection device (not shown) or the like.
5, thereby switching and applying negative pressure suction force and discharge air pressure to the suction/discharge bracket 10 that slides with respect to the casing 18 at the lower end of the casing 18 and in front of the peeling fitting 4. ing.

Therefore, the control device 2 is installed on the lower side of the casing 18.
A solenoid 26, which serves as a reciprocating device and is electrically connected to the casing 18, is fixed to the guide groove 27 of the casing 18 via a fitting 28.

A suction/discharge bracket 10 that is slidable in a guide groove 27 is fixedly connected to the tip of the rod 29 of the solenoid 26, and a compression spring 30 is installed between the suction/discharge bracket 10 and the solenoid 26 on the outside of the rod 29. It has been intervened.

Reference numeral 31 denotes a plurality of slits, which are bored along the forward and backward direction of the suction/discharge bracket 10, and the width, number, etc. of the slits are designed so that the label 2 can be easily attracted and lowered.

<Embodiment - Effects> In the above-described configuration, the mount 1 is transferred from the feed reel 3 on which the sheets 15, each of which has been successively attached to the mount 1, is wound in advance, and the mount 1 is transferred to the guide pulleys 16, 16, . . . The tension pulley 17, drive roller 32, and peeling fitting 4 are passed through the label, the label is wound onto the take-up reel 5, and the display label is suctioned and pasted via the control device 25 in synchronization with the feeding of the package tray 8 as the object to be pasted. The installation device 12 is activated.

When the sheet 15 fed by the rotation of the drive roller 32 and the take-up reel 5 is taken up with the mount 1 retreating at a steep slope at the peeling fitting 4, the mount 1 and the printing machine At step 6, due to the difference in hardness between the label 2 and the label 2 on which a predetermined weight, unit price, price, etc. are printed, the label 2 is peeled off from the mount 1 and is fed forward, and is fed to the lower surface of the suction/discharge bracket 10 of the pasting device 7. be done.

In this state, the dampers 22 and 22' of the duct of the pasting device 7 have been switched to the state shown in FIG. Due to the negative pressure, the suction/discharge bracket 10 is attracted to the lower surface of the suction/discharge bracket 10 and maintained in that position.

As for the maintained label 2, the mount 1 is fed intermittently as described above, so that the rear end of the label 2 is slightly attached to the mount 1 when the mount 1 is stopped.

Therefore, the solenoid 26 is retracted at a predetermined timing under the timer control of the control device 25, and the suction/discharge bracket 10 is slightly advanced a predetermined distance against the compression spring 30. Peel from.

When the package tray 8 reaches there directly below, the dampers 22 and 22' are instantly switched as shown in FIG. They are switched at the same time, and the exhaust air from the suction/exhaust bracket 10 acts to apply a downward pressure to the label 2.

Thereupon, the label 2, which had been in an adsorbed state until then, is lowered directly below under the discharge pressure, and is correctly affixed in a predetermined posture to a predetermined position on the waiting object 8, such as a package tray.

Therefore, in this case, the descending label 2 will not be reattached to the mount 1.

After the dampers 22, 22' are switched as shown in FIG. 10 is in the rear position again, and the control device 25 controls the switching dampers 22, 2.
2' is switched to the position shown in FIG. 4, and negative suction pressure is applied to the suction/discharge bracket 10 in preparation for forward feeding of the next label 2.

Then, the next label 2 is advanced through the control device 25, and the above-described cycle is repeated, and the labels 2, 2, . . . corresponding to the package trays 8, 8, .

The embodiment shown in FIG.
This is a branched version shown in FIG. 1 in contrast to the conventional embodiment shown in the figure.

It goes without saying that the embodiments of this invention are not limited to the above-mentioned embodiments; for example, various embodiments may be adopted, such as making the stroke of the solenoid adjustable with a stepped stopper or the like.

<Effects of the invention> As described above, according to this invention, when the labels individually attached to the mount are attached to an object to be affixed such as a package tray, the labels are absorbed and discharged by peeling from the mount via the peeling fitting. In the process of feeding the label to the bracket and adsorbing it, the label is reliably peeled off from the backing paper, and is therefore reliably lowered to the object to be affixed, such as an incoming package tray, and maintains a predetermined posture relative to the set position. This has the excellent effect of not being attached to the mount again.

Therefore, serious accidents such as pasting errors (no labels) can be eliminated, and there is no variation in the pasting position, and reliable pasting is possible, and defects such as the label edges lifting up are also prevented, which reduces the product value. It has a unique effect.

As a result, the suction/discharge bracket is moved back and forth a set distance with respect to the duct of the pasting device by a reciprocating device such as a solenoid installed in the pasting device, so that the label can be removed from the backing paper by intermittent winding with the peeling tool. Even if the rear end of the label is slightly attached to the backing paper during the peeling process, an excellent effect is achieved in that it can be reliably separated in an adsorbed state.

Moreover, since the suction/discharge label simply slides sideways and this is done quickly, there is an advantage that the suction effect is not affected in any way, and the blow-out descent is also not affected in any way.
