Abstract

PURPOSE:To surely position a packaging article, by providing a direction change-over guide surface for articles to be conveyed, which is obliquely arranged with respect to the conveying direction of a first conveyer, on the latter, and by arranging a second conveyer, obliquely with respect to a positioning guide surface for the articles to be conveyed, which is continuous to the afore-mentioned guide surface. CONSTITUTION:When one side 21a of a packaging article 21 makes contact with a guide surface 14a on a first conveyer 3, the one side 21a of the packaging article 21 slips on a conveying member 9 so that is advances bit by bit along the guide surface 14a while the other side 21b of the article 21 rides on the conveying member 9, and therefore, the packaging article 21 is gradually rotated toward the conveying direction A side of the first conveyer 3 about the one side 21a thereof. When the one side 21a is shifted onto a guide surface 20 on a second conveyer 4, the other side 21b is rotated so as to approach the guide surface 20a, comparatively. Thereafter, the other side 21b is made to approach the guide surface 20a, being along the conveying direction B of the second conveyer 4, and therefore, makes contact with the guide surface 20a. Thus, the direction of the packaging article is changed over, and is conveyed, being held against the guide surface under a slight force while the longitudinal direction of the article is along the guide surface 20a.

Description

DETAILED DESCRIPTION OF THE INVENTION Purpose of the Invention (Field of Industrial Application) The present invention relates to a packaging machine (Japanese Unexamined Patent Application Publication No. 61-142109
(Refer to Japanese Patent Publication No. 2003-110001), relates to a device that changes the orientation of a packaged product, positions the packaged product, and then conveys the packaged product to a labeling device when attaching a weighing label to the packaged product.

(Prior Art and Problems to be Solved by the Invention) Conventionally, as a device for positioning a packaged product in order to attach a measurement label to the packaged product, there is one described in Japanese Utility Model Application Publication No. 61-49728.

Usually, the tray before packaging is placed on a conveyor with its longitudinal direction perpendicular to the conveyance direction, and after packaging, the tray is placed on a conveyor belt with its longitudinal direction perpendicular to the conveyance direction. . The packaging machine disclosed in the above-mentioned prior art publication is also of this type.

In the packaged product positioning device of the packaging machine, the packaged product is placed in the above-mentioned unloaded state and positioned with its negative side along the guide surface. Then, the packaged product is transported in this unloaded state to a labeling device, and a weighing label is pasted at a predetermined position on the packaged product.

However, when the longitudinal direction of the packaged product is perpendicular to the conveyance direction and one side contacts the guide surface, the distance from the contact point to the other side of the packaged product is long, so the conveyance force applied to the other side causes the same A rotational moment is generated around the contact area,
There was a risk that the packaged product would tip. When the packaged product is tilted, the label can be applied at different positions, and in some cases, it may become impossible to apply the label to the packaged product.

Therefore, by improving the positioning of the packaged product by changing the orientation of the packaged product so that the longitudinal direction of the packaged product is along the conveyance direction, the tilting of the packaged product can be eliminated and the label can be placed at a fixed position on the packaged product. The present invention enables the adhesive to be reliably attached to the surface.

Structure of the Invention (Means for Solving Problems) That is, as shown in the drawings of embodiments described later, the present invention comprises a first conveyor 3 equipped with a rotatable conveyor 9 and a rotatable conveyor 16. The second conveyor 4 provided is connected to the second conveyor 4,
On the first conveyor 3, there is provided a guide surface 14a for changing the orientation of the transported object, which is oblique with respect to the transport direction A, and on the second conveyor 4, there is provided a guide surface 20a for positioning the transported object, which is continuous with this guide surface 14a. It is provided substantially along the conveyance direction A of the first conveyor 3, and the conveyance direction B of the second conveyor 4 is oblique with respect to this guide surface 20a.

(Function) The conveyed object, for example, the packaged product 21, is conveyed onto the conveying body 9 of the first conveyor 3 with its longitudinal direction perpendicular to the conveying direction A. As shown by the imaginary line P1 in Figure 1, the packaged product 2
When one side 21a of the first conveyor 3 comes into contact with the guide surface 14a on the first conveyor 3, the resistance generated between them causes the packaged product 21 to
One side 21a slips with the conveyor 9 and moves little by little along the guide surface 14a, but the other side 21 of the packaged product 21
b travels on the carrier 9. Therefore, the imaginary line P2 in FIG. As shown in P 3, the packaged product 21 has one side 2
It gradually rotates around 1a in the transport direction A side. The rotation is facilitated when the other side 21b of the packaged product 21 is placed on the carrier 16 of the second conveyor 4.

As shown in imaginary MP 4 in FIG. 21b rotates and approaches the guide surface 20a considerably. After that, the other side 21b of the packaged product 21 is transferred to the second conveyor 4.
It is further brought closer to the guide surface 2Oa side along the conveyance direction, and comes into contact with the guide surface 20a as shown by an imaginary line P5 in FIG. In this way, the orientation of the packaged product 21 is changed so that its longitudinal direction is along this guide surface 20a. In this state, the packaged product 21 is conveyed along the guide surface 20a while being lightly pressed against the guide surface 20a.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

The packaging product orientation conversion/positioning device 1 according to the present embodiment is used to transport a packaging machine (not shown, but as shown in Japanese Patent Application Laid-Open No. 61-142109, a tray containing stored items is wrapped with a resin film). It is arranged continuously with the heater device 2 in the section.

After the film overlapping portion of the packaged product 21 is thermally bonded by the heater device H2, the packaged product 21 is conveyed to the apparatus 1.

Next, the present device 1 will be explained in detail. This device 1 is a shipboard heater equipment [
2, and a second conveyor 4, which is connected to this conveyor 3.

In the first conveyor 3, a plurality of endless round belts 9 (carrying bodies) having a circular cross section are passed in parallel between a pair of pulleys 7 and 8 supported by the machine frames 5 and 6, and inside them A droop prevention plate 10 is installed on the machine frame 5, 6fl. A drive motor 11 is attached to one machine frame 5 and is interlocked with one pulley 8.

A substantially quarter-arc-shaped support plate 13 is mounted on a pair of support columns 12 fixed to one machine frame 5 near the drive pulley 8, and the support plate 13 is inserted through a long hole 13a formed in the support plate 13. A positioning screw 12a is screwed together. The outer peripheral arc portion of the support plate 13 is located above the endless round belt 9 of the first conveyor 3, and a plurality of guide rollers 14 are rotatably supported along the lower surface of the arc portion.

A guide surface 14a connecting the outer peripheral surfaces of each guide roller 14 is oblique with respect to the conveyance direction A of the endless round belt 9 of the first conveyor 3.

In the second conveyor 4, a plurality of similar endless round belts 16 (ill conveyor) are passed in parallel between the drive pulley 8 and the pulley 15 supported by the double frame 5.6. On the inside, the sagging prevention plate 17 is attached to the frame 5.
It is constructed between 6 rooms.

A rod 1 is attached to a pair of supports 18 fixed to one machine frame 5.
9 is movably inserted, and a rod 19 is mounted on this support 18.
A positioning screw 18a is screwed together. A guide plate 20 is fixed to both rods 19 on the endless round belt 16 of the second conveyor 4, and its guide surface 20a is a guide surface 14a formed by each guide roller 14 along the conveyance direction A of the first conveyor 3. It is continuous. Further, the conveying direction B of the endless round belt 16 of the second conveyor 4 is oblique with respect to the guide surface 20a.

Now, in the present I apparatus 1 configured as described above, first, the guide roller 1 on the first conveyor 3 is
4 and the position of the guide plate 20 on the second conveyor 4 is adjusted. The drive motor 11 of the device 1 is driven as the packaging machine is operated, and each endless round belt 9, 16 is rotated by this drive.

The packaged product 21 is carried onto the heater device 2 so that its longitudinal direction is perpendicular to the transport direction A, and the film overlapping portion of the packaged product 21 is thermally bonded there.

The packages 21 on the heater device 2 are conveyed onto each endless round belt 9 of the first conveyor 3 in this unloaded state.

One side 21 of the packaged product 21 as shown by the imaginary line P1 in FIG.
When a contacts the guide rollers 14, one side 21a of the packaged product 21 slips between it and the endless round belt 9 due to the resistance generated between them, and gradually slides along the guide surface 14a of each guide roller 14. However, the other side 21b of the packaged product 21 is placed on the endless round belt 9 and moves forward. Therefore, the imaginary line P2 in FIG. As shown in P 3, the packaged product 21 gradually rotates in the transport direction A side around one side 21a thereof. The rotation is facilitated when the other side 21b of the packaged product 21 rests on each endless round belt 16 of the second conveyor 4.

As shown by the imaginary line P4 in FIG.
1a moves from the guide surface 14a of each guide roller 14 to the guide surface 20a of the guide plate 20 of the second conveyor 4, the other side 21b of the packaged product 21 rotates and approaches the guide plate 20 considerably.

Thereafter, the other side 21b of the packaged product 21 is further moved toward the guide plate 20 along the conveyance direction mill of each endless round belt 16 of the second conveyor 4, and the guide plate 20 is moved as shown by the imaginary line P5 in FIG. It contacts the surface 20a. In this way, the orientation of the packaged product 21 is changed so that its longitudinal direction is along this guide surface 20a. In this state, packaged product 21
is lightly pressed against the guide surface 20a while the guide surface 2
It is conveyed along 0a.

A labeling device (not shown) is successively arranged in the device 1, and the packaged product 21 is conveyed to this labeling device in the above-described state.

In particular, in this embodiment, the longitudinal direction of the packaged product 21 is the conveyance direction A.
Even if the packaged product 21 is carried out onto the heater device 2 so as to be perpendicular to the
The packaged product 21 is conveyed to the labeling device while being in contact with the guide surface 20a of the guide plate 20, with the longitudinal direction of the packaged product 21 being along the guide surface 20a of the guide plate 20. Therefore, this guide surface 20a
The width of the packaged product 21 in the direction perpendicular to is shortened, and the risk of the packaged product 21 tilting due to rotational moment caused by the conveyance force is reduced compared to the case of the prior art described above.

In addition, since the endless round belt 9.16 is used for the first and second conveyors 3.4, the belt 9.16 and the film overlapping part of the packaged product 21 are in line contact, and the contact area is This makes it difficult for the polymerized portion of the film to peel off.

Furthermore, the direction in which the line contact portion extends is substantially the same as the transport directions A and B of the packaged product 21, reducing the possibility that the film overlapping portion will be caught in the endless round belts 9, 16.

In addition, in the embodiment described above, each guide roller 14 on the first conveyor 3 is forcibly rotated, and the second conveyor 4 is
Instead of the upper guide plate 20, a flat belt may be rotatably hung or forced to rotate. Further, instead of the endless round belt 9.16, a roller or a flat belt may be used as the conveyor.

Effects of the Invention In short, according to the present invention, even if the packaged product 21 is carried out such that the longitudinal direction of the packaged product 21 is orthogonal to the conveyance direction A, the direction of the packaged product 21 is changed and the packaged product Since the packaged product 21 is conveyed to, for example, a labeling device while being in contact with the guide surface 20a with the longitudinal direction of the packaged product 21 along the guide surface 20a, the width of the packaged product 21 in the direction orthogonal to the guide surface 20a is As a result, compared to the case of the prior art described above, there is less risk of the packaged product 21 being tilted due to rotational moment caused by the conveying force. Therefore,
The packaged product 21 can be positioned reliably, and for example, a label can be reliably pasted on the packaged product 21 at a fixed position.
