Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a direction regulating device suitable for regulating the conveyance direction of a cylindrical conveyance object having a flat hole in its center, such as a hakama for conveying a container. It is something.

[Conventional technology]

Generally, when filling a flexible, flat plastic container with a liquid or viscous substance or performing other processing, the container is inserted into a cylindrical hakama with a hole that has a flat cross section, and the container is transported on a conveyor while being processed. However,
At this time, if the hakama are aligned in a certain manner according to the direction of the side holes, it will be very easy to automate the insertion of containers into the hakama and the removal of containers from the hakama.

In order to meet these demands, previously
-As shown in Publication No. 11758, grooves parallel to each other are provided on both sides of the hakama, and the grooves of the hakama being transported along the conveyor can be inserted into the guide bar at the top of one side of the conveyor that transports the hakama. At the same time, a plurality of pulleys are arranged along the other side of the conveyor, and these pulleys are placed at the same height as the guide and whose separation distance from the guide bar is larger than the diameter of the hakama. A belt set to be slightly narrower is wound around the hakama, and the belt is driven at a speed higher than the conveyance speed of the conveyor.The hakama is rotated during conveyance, and its concave grooves are engaged with the guide bar. Alternatively, slits may be formed on the underside of the hakama to restrict the direction, and protrusions are provided at predetermined intervals on the conveying surface of the conveyor that transports the hakama, and the hakama on the conveyor is placed on the upper side of the strip at predetermined intervals. A spiral conveyor for separating the hakama is grounded, and a belt mechanism similar to the one described above is arranged on the other side, and the direction of the hakama is controlled by rotating the hakama while it is being transferred and engaging the slits of the hakama with the protrusions on the conveyor. ing.

[Problem that the invention attempts to solve]

However, conventional devices in which the belt mechanism only functions as a biasing means for biasing the hakama toward the area where the guide bar and the groove or convex slit engage are complicated in structure and high in cost. In addition, it is difficult to adjust the biasing force, and the outlet guide portion may become clogged due to poor engagement due to insufficient direction regulation, resulting in reliability problems. In particular, in the former case, if even part of the groove is engaged with the guide bar, the hakama on the conveyor is positioned closer to the guide bar, so the urging force by the belt mechanism is significantly reduced. Otherwise, it may disappear, making it impossible to fully demonstrate its functions.

SUMMARY OF THE PRESENT DISCLOSURE In view of the above, it is an object of the present invention to provide a direction regulating device for cylindrical objects to be transported which has a simple structure, can reduce costs, is easy to maintain and manage, and can improve reliability.

[Means for solving problems]

The direction regulating device for a cylindrical conveyed object according to the present invention is
A conveyor for conveying a cylindrical conveyed object having a magnetic adsorbent attached to a flat part in a groove formed on the circumferential surface, and a conveyor provided on one side of the conveyor and driven at a speed different from the conveyance speed of the conveyor. an endless band that can be fitted into the groove of the cylindrical conveyed object, and a magnetic element that is provided on the back side of the endless band and that attracts the magnetic attraction body through the endless band to regulate the direction of the cylindrical conveyed object. and guide means for guiding the cylindrical conveyed object into a region where the magnetic force of the magnetic body acts on the magnetic attracting body.

[Effect]

In the present invention, a cylindrical conveyed object that is being transferred near the don bear is rotated so that the magnetic attracting body part on its circumferential surface is attracted to the belt by the magnetic force of the magnetic body, and the flat part of the cylindrical conveyed object is more strongly attracted to the belt. Since the conveyor is attracted, its rotation is prevented, and its direction is restricted, there is basically no need to provide a biasing means for the conveyed object on the other side of the conveyor, and the structure can be simplified.

〔Example〕

An embodiment of the device of the present invention is shown in Figs. 1 to 3 below.
To explain based on the drawings, the direction regulating device according to the present embodiment is such that the hakama 2 transferred to the conveyor 1 on the conveying surface 1a has a flat hole 2a in the central part, as shown in FIGS. 2 and 3. It is also formed from a resin cylindrical shape with mutually parallel grooves 2b and 2c carved on both sides of the lower part, and flat portions 2d and 2e forming the bottoms of the grooves 2b and 2c, and flat portions 2d and 2e at both ends of these flat portions. Magnetic adsorbents 3a and 3b are attached to a part of the periphery of the continuous hakama and are divided into two parts on both sides of the hakama.

The conveyor 1 is equipped with a pair of pulleys 4a and 4b on one side, and between these pulleys, the grooves 2b and 2c of the hakama 2 fit into the belt 5, which is driven at a faster speed than the conveyor conveyance speed. At the same time, on the back side of the loop formed by the belt 5 on the conveying surface 1a side, a magnetic body 6 is attached to the belt, the width being set to be the same as the belt width dimension or slightly narrower than that. They are arranged side by side and are configured to be able to attract the magnetic attracting bodies 3a and 3b of the hakama 2 through the belt 5.

By the way, in this embodiment, two upper and lower guide bars 7a and 7b are provided on the other side of the conveyor 1 and separated from the belt 5 by a distance approximately equal to the diameter of the hakama 2. body 3a, 3
b, the hakama 2 is guided so as to move within a range where it can be attracted by the attraction force of the magnetic body 6 provided on the back side of the belt 5. If even a part of the magnetic attracting bodies 3a, 3b attached to the flat parts 2d, 2e in the concave grooves 2b, 2c comes into contact with the belt 5, it will separate from the guide bars 7a, 7b from that point on, and its peripheral surface will be removed. It is attracted to the belt 5 and rolls on the belt 5 surface, and is more strongly attracted to the belt at the flat part 2d or 2e.
Since the rotation thereof is prevented and the direction is restricted, the guide bars 7a and 7b do not constitute biasing means like a conventional belt mechanism.

In addition, in this embodiment, the hakama 2 has concave grooves 2b and 2c carved on both sides, and flat portions 2 in these concave grooves.
Although magnetic adsorbents 3a and 3b are shown to be adhered to parts of the circumferential surfaces extending from d and 2e to both ends thereof, the present invention is not limited to this, and for example, it is possible to One side only.

In this embodiment, as shown in FIGS. 6 and 7, the hakama 2 is covered with magnetic adsorbents 3 on both sides from the flat portions 2d and 2e in the grooves 2b and 2c to the entire lower peripheral surface continuous to these. The conveyor 1 that conveys the hakama 2, which has been formed and has a magnetic adsorbent 3 attached to its entire circumference, has pulleys 4a and 4b similar to the first embodiment, a belt 5, and a magnetic belt installed on one side of the conveyor 1. An idle pulley 4c is provided at the hakama introducing portion of the suction belt mechanism 8 consisting of the body 6 to slightly bend the belt 5 inward of the conveying surface 1a, that is, in a direction perpendicular to the conveying direction of the conveyor 1. A short magnetic body 6a on the back side of the belt at this bent portion is arranged separately from the above-mentioned magnetic body 6, and on the other side of the conveyor at this bent portion, a position is separated by the diameter of the hakama 2 from the belt at this bent portion. A short guide 9 is provided in parallel to each other.

In this embodiment, even when the hakama 2 is transferred on the conveyance surface 1a with the flat part in the groove parallel to the conveyance direction, the suction belt mechanism 8 has Since the concave groove engages with the belt 5 and a part of the magnetic attracting body 3 can be reliably attracted to the belt 5, the guide bar shown in the above embodiment can be made unnecessary.

In this embodiment as well, the hakama 2 has flat parts on only one side (Fig. 4 d), those with two flat parts on one side (Fig. 4 e), and those with multiple flat parts in a polygonal shape (Fig. 4 e). 4(f) and the like can be adopted, and the same effects as those of the above embodiment can be achieved.
