Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is capable of scraping and positioning a tubular label when transferring an article such as a can or bottle container to which the tubular label is fitted. The present invention relates to a tubular label positioner for a screw type conveyor device.

(Prior Art) Conventionally, as a means for carrying out both the work of transferring an article equipped with this type of label and the scraping of the label, there has been a practice of using the actual construction 63-12.
There is one described in Japanese Patent No. 0809.

As shown in FIG. 5, this conventional one is provided with an elastic friction material 20 in the feed groove 4 of the screw 3e for transferring the container 2 having the label 14 fitted thereon.

According to such means, when the bottle container 2 having the tubular label 14 fitted on the upper portion thereof is engaged with the spiral feed groove 4 of the screw 3e and is transferred at a constant pitch, as shown in FIG. label
The 14 can be scraped down sequentially by contact with the friction material 20. Therefore, there is no need to install a scraping device dedicated to the label separately from the screw type conveyor device, and there is an advantage that space can be saved.

(Problems to be solved by the invention) Therefore, in this type of label mounting work, even when the containers of the same size are targeted for transportation, the label 14 to be mounted on the container is changed according to the size change or the like. In some cases, the scraping-down dimension L of 14 may need to be changed appropriately.

However, in the conventional means, the label 14 on the outer circumference of the container is continuously scraped off while being transferred in contact with the friction material 20 of the screw 3e, the descending amount of the label 14 and the total length of the friction material 20. It is in direct proportion to the size. Therefore, even if it is necessary to change the descending amount of the label 14, for example, it cannot be easily changed. In order to increase or decrease the descending amount of the label 14, the friction material 20 attached to the screw 3e is changed to a friction material having another dimension, or the screw 3e itself is provided with a friction material having a different length. I have to change it. Therefore, the change work is very complicated and has a problem in terms of workability.

Further, as another problem, in the above-mentioned conventional one, since the spiral friction material 20 rotates in contact with the label 14, the friction material 20 not only causes a downward force to the label 14. Torsion force is also generated at the same time. This is because the contact position between the label 14 and the friction material 20 sequentially moves along the spiral direction as the screw 3e rotates. Therefore,
When the label 14 is soft, for example, the twisting of the label 14 causes a large amount of wrinkles, which makes it difficult to mount the label in a good appearance.

Therefore, in the present invention, when a screw type conveyor device is provided with a label scraping device to save the space of such a device, the label descending amount can be easily increased or decreased, and the label can be lowered. Its purpose is to make it possible to scrape and attach an appropriately beautiful label without exerting an unreasonable twisting force on the.

(Means for Solving the Problem) The present invention does not provide a spiral friction material on the outer peripheral surface of the screw as in the prior art, but scrapes the label directly downward on a part of the conveying path of the screw type conveyor device. The above means is integrally incorporated so as not to hinder the carrying work, and thus the above-mentioned conventional problems are solved.

That is, firstly, the present invention has a spiral feed groove 4 on the outer peripheral surface.
A label attachment 2 having a lower end of a cylindrical label 14 fitted from above is configured to be movable along the screw 3 and is rotatably provided with a screw 3 that forms the label. In a screw type conveyor device equipped with a scraping means for scraping 14 downwards with respect to the label-mounted article 2, a cutout groove portion 13 is provided on a part of the outer peripheral surface of the screw 3, and the scraping means is The label scraping rotor 7 is provided in the notched groove portion 13 so as to face the transfer path side of the label attachment 2, and the label scraping rotor 7 is transferred to the position of the notched groove portion 13. A cylinder in a screw type conveyor device, which is rotatably provided downward independently of the rotation operation of the screw 3 in order to lower the label 14 of the label attachment 2 to a predetermined position. A positioner for the label.

Secondly, according to the present invention, in the above-mentioned configuration, the label scraping rotary member 7 is paired with the label scraping rotary member 7 at a position facing the label scraping rotary member 7 across the transfer path of the label mounting member 2. Incidentally, another label scraping rotator 7a for scraping the label of the label-mounted article 2 is provided so as to be driven and rotated downward at a dynamic speed together with the one label scraping rotator 7a. .

Thirdly, according to the present invention, in any one of the above configurations, the notch groove portion 13 has a spiral feed groove 4 of the screw 3 so as to temporarily stop the transfer of the label mounting object 2 by the screw 3.
Is formed in a non-spiral circumferential groove shape, and the label scraping rotator 7 faces the support shaft 6 located in the notch groove portion 13 via a bearing 8. It is configured as a roller to which a driving torque is applied by a separately provided electric motor 11 which is fitted and mounted so as to idle.

(Operation) In the apparatus characterized by the above-mentioned structure, when the label attachment 2 transferred along the screw 3 reaches the notch groove portion 13, the label scraping rotary member 7 is applied to the label 14. The scraping can be done by rotating them in contact with each other.

Thus, the descending size of the label 14 is directly proportional to the rotation angle of the label scraping rotor 7, but the label scraping rotor 7 is rotatable independently of the screw 3. Therefore, the rotation speed and the like can be set separately from the screw 3. Therefore, the descending amount of the label 14 can be arbitrarily changed by appropriately changing the rotation angle of the label scraping rotator 7.

Further, since the label scraping rotator 7 is disposed in the notch groove portion 13 provided on a part of the outer peripheral surface of the screw 3 so as to rotate downward, the label scraping rotator 7 scrapes down the label. Applying an unreasonable twisting force to the label 14 to be displayed is also eliminated.

Further, in the above-mentioned second configuration, a pair of label scraping rotors 7 and 7a provided to face each other are brought into contact with both sides of the label 14 of the label attachment 2 and both sides thereof are contacted. The scraping can be done evenly, and the scraping work becomes even more accurate.

Further, in the case of the third configuration, the label attachment 2 to be transported by the screw 3 can be temporarily stopped at the position of the notch groove portion 13 formed in the non-spiral circumferential groove shape. The scraping work can be accurately performed when the label-attached article 2 is stopped, and at the same time, the work for transferring the label-attached article 2 by the screw 3 can be smoothly performed. Further, since the label scraping rotator 7 is configured as a roller that is fitted to the support shaft 6 of the screw 3 so as to rotate idly and is rotationally driven by the electric motor 11, the label scraping rotator 7 is Needless to say, it can be driven and rotated independently of the screw 3, and its configuration is very simple.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a belt conveyor for placing and transferring the bottle container 2. Reference numeral 3 denotes a screw provided along one side of the belt conveyor 1, and two screw bodies 5, 5a having spirally formed feed grooves 4 having an arc-shaped cross section on the outer peripheral surface.
Is externally fitted and fixed in series to a single support shaft 6 which can be driven and rotated by an electric motor or the like (not shown).

Reference numeral 13 denotes a notched groove portion formed as a gap portion formed between the two screw bodies 5 and 5a, which is formed as a non-spiral circumferential groove. The ends of the feed grooves 4 and 4 of 5a and 5a are connected in series.
Reference numerals 15 and 15a denote concave chamfered portions provided at the ends of the screw bodies 5 and 5a, respectively, for smoothly inserting and removing the label attachment 2 into and from the notch groove portion 13.

Reference numeral 7 is a label scraping roller interposed at the position of the notch groove portion 13, and corresponds to an example of a label scraping rotary member according to the present invention. The roller 7 is a support shaft 6 for the screw 3. The support shaft 6 is fitted into the support shaft 6 via a bearing 8 so as to be idle. Reference numeral 10 denotes a driving roller for applying a rotational driving force to the roller 7 by frictional conduction or the like, which can be driven and rotated by an electric motor 11.

7a is another roller for scraping the label which is paired with the roller 7, and is provided on the other side of the conveyor 1 on the other side.
It is provided opposite to and can be driven and rotated by the electric motor 11a at the same speed as the other roller 7. Further, the outer peripheral surfaces of both scraping rollers 7 and 7a are appropriately coated with rubber or the like or irregularities so as not to slip with the label. A fixed guide 12 is provided on the other side edge of the belt conveyor 1 except for the position of one scraping roller 7a.

The present embodiment has the above-mentioned structure. Next, its use example and operation will be described.

First, the bottle container 2 formed by fitting the cylindrical label 14 on the upper part is supplied onto the belt conveyor 1 and partly fitted into the feed groove 4 of the screw head 3, and the bottle container 2 rotates the screw 3 It is transported to the downstream side under the regulation of the feeding groove 4 of.
The bottle container 2 guided by the feed groove 4 of the screw body 5 on the upstream side has a notch groove portion which is subsequently provided with the feed groove 4.
Although it is guided to the position of 13, the notch groove portion 13 is formed in the shape of a non-spiral circumferential groove, so that the transfer of the belt conveyor 1 can be performed even if the movement of the belt conveyor 1 and the rotation of the screw 3 are continued. Is suspended. Further, when the feed groove 4 of the screw body 5a on the subsequent stage is then rotated toward the label-attached article 2 side, the transfer of the bottle container 2 is restarted again.

Here, when the label attachment 2 is transferred to the position of the cutout groove portion 13, a pair of label scraping rollers 7 and 7a come into contact with both side surfaces of the label 14 fitted on the upper portion of the bottle container 2. To do. Therefore, at that time, if the electric motors 11 and 11a are operated and both rollers 7 and 7a are rotated, the label 14 is scraped down along the bottle container 2 to the desired height position of the bottle container 2 with the label 14. Can be used for body positioning. The scraping work of the label can be surely performed because the transfer of the label-attached object 2 is stopped, and the two rollers 7 and 7a can be individually brought into contact with both side portions of the label 14, respectively. There is no risk of tilting or the like.

Thus, the pair of label scraping rollers 7 and 7a do not rotate spirally and only lower the label 14 in the vertical direction, so that the label 14 is not twisted. It does not cause any undue wrinkles. Therefore, the appearance of the label 14 that has been scraped off can be favorably set.

Further, the descending dimension of the label 14 is proportional to the rotation angle of the rollers 7 and 7a, but the descending dimension of the label 14 can be increased or decreased only by changing the rotation angle (rotation number) of the rollers 7 and 7a. The rotation angle can be easily changed because the rotation speeds of the electric motors 11 and 11a provided separately from the screw 3 can be changed.

In the above embodiment, the label scraping rotors 7 and 7a are used.
Although a pair is provided and they can be brought into contact with both sides of the label 14, the present invention does not necessarily have to be configured in this way. For example, one roller 7a may be removed, and the label scraping roller 7 may be brought into contact with only one side of the label 14 to scrape it. Even with such a configuration, when the label 14 is relatively hard, appropriate scraping work can be performed.

Further, in the above embodiment, the gap portion provided between the two screw bodies 5 and 5a of the screw 3 is configured as the notch groove portion 13. However, the concrete forming means and position of the notch groove portion 13 according to the present invention, and the The specific form is not limited to this.

For example, as shown in FIG. 2, a hole 16 is formed from the end portion side of the screw 3 along the central axis of the screw 3 to form a partially cutout groove portion 13 on the outer peripheral surface of the screw 3. Alternatively, the support shaft 6 may be fitted with the roller 7 having a bearing therein. Even when placed on such means, it is possible to rotate the roller 7 independently while the roller 7 is exposed to the outer surface side of the screw 3 to appropriately scrape the label. Further, the notch groove portion 13 may be provided not only at the central portion of the screw 3 but also at the end portion side.

Further, in the present invention, the roller 7 may be set wider than the feed groove 4 of the screw 3 regardless of the specific size of the roller 7. Further, the cutout groove portion 13 does not necessarily have to be formed as a temporary stop of the transfer of the label-mounted product 2 while the screw 3 continues to rotate. The screw 3 may be intermittently rotated to scrape the label when the rotation of the screw 3 is stopped, or when the transfer speed of the label-attached article 2 is low, the label-attached article 2 is transferred and the label is removed. It is also possible.

On the other hand, in the present invention, the structure of the label scraping rotator 7 is not limited to the roller as described above, and a brush having a large frictional force with the label may be used as the rotator. Also,
As shown in FIG. 3, the belt 7 arranged so as to pass through the position of the notch groove portion 13 of the screw 3 may be set to be circulatively movable so that the label 7 can be scraped down by the belt 7. .

Further, in the present invention, it is a requirement that the label scraping rotator 7 is configured to rotate independently of the rotation operation of the screw 3, which is the same as the above embodiment.
The means for using the electric motor 11 dedicated to For example, by adopting a drive system for rotation of the screw 3 as its drive force, and providing a transmission with a clutch for exclusive use in the path for transmitting the drive force to the label scraping rotary member,
The rotating bodies 7 may be individually controlled to rotate. Further, as a specific means for applying a driving force to the rotating body 7, a belt, a churn, a gear or the like other than frictional conduction may be appropriately used.

Further, in the present invention, the concrete constitution of the screw type conveyor device is not limited as in the above embodiment, and the concrete constitution of each part such as the screw 3 can be arbitrarily changed in design. For example, as shown in FIG. 4, one in which two screws 3 and 3 are arranged side by side and label scraping rollers 7 and 7 are provided on the respective screws 3 and 3 are also within the technical scope of the present invention. Belong to.

In addition, the present invention is not limited to the bottle container 2 as the specific type of the label-attached article 2, and can be applied to any article to which the label is fitted.

(Effect of the Invention) As described above, according to the present invention, in the notch groove part provided on the outer peripheral surface of a part of the screw, the label scraping rotary member rotatable independently of the screw rotation operation is attached to the label-attached object. The label scraping device does not need to be provided at a position separate from the screw type conveyor because the label mounting object transferred to the position of the notch groove portion can be scraped down by facing the transfer path. Not only can the entire device be made compact and space-saving, but even when it is necessary to increase or decrease the descending size of the label,
There is no need to perform complicated work such as replacing the contact body mounted on the screw as in the past, and it is very simple to simply increase or decrease the rotation angle of the rotatable label scraping body independent of the screw. It can be dealt with by a simple adjustment work, has excellent adaptability to the changing work, and has a special effect that is optimal for positioning work of various tube heights.

Moreover, in the present invention, since the label scraping rotator is provided so as to rotate downward, the label scraping is performed by the friction material along the spiral feed groove of the screw as in the conventional means. There is also the effect that a beautiful label descent finish can be performed without the fear that a twisting force will be generated in the label and a large amount of wrinkles will be generated in the label.

Further, since the label 14 having the lower end fitted to the label-attached article is externally fitted to the label-attached article, since the label is scraped down by the label scraping / rotating body provided at the transfer portion of the label-installed article in the screw, the label has a diameter of the label. It is possible to forcibly and surely scrape the label, which is externally fitted to the label-mounted product, to a predetermined position even if the label is not large enough to the diameter of the mounted product.

Therefore, it is not necessary to unnecessarily increase the diameter of the label 14, and it is possible to reduce the material cost of the label and reduce the shrinkage error of the label, especially when the label is heated and shrunk, and the wrinkle of the label and the design distortion. Can be effectively prevented.

Further, according to the means for providing another rotating body which rotates in a pair with the label scraping rotary member at a predetermined position facing the label scraping rotary member of the present invention, the pair of rotary scraping members are rotated. There is an advantage that the label can be brought into contact with both sides of the label and the both sides can be evenly scraped off, and the scraping work can be performed more appropriately and beautifully.

Further, according to the present invention, the means for temporarily stopping the label-attached article to be transferred by the screw at the position of the notch groove formed in the non-spiral circumferential groove shape allows the label to be scraped down while the screw rotation operation is continued. According to the means configured so that the work can be reliably performed when the label-mounted object is stopped, and the label scraping rotator is idlely fitted to the support shaft of the screw and is configured to be driven to rotate by the electric motor. Is very simple and easy to manufacture, and its practicality is even greater.
