Description

Detailed Description of the Invention (Industrial Application Field) The present invention is directed to changing the direction of a rod-like object discharged from a transport pipe by pneumatic transport from feeding in the longitudinal direction of the axis to feeding in a direction crossing the longitudinal direction of the axis. The present invention relates to a receiving device for pneumatically transported sticks to be transferred to a storage section.

(Prior Art) Conventionally, this type of receiving device for pneumatically transported sticks has been disclosed, for example, in Japanese Patent Publication No. 58-56686, in which a central axis is set between the ejection path of the sticks and parallel to the ejection path. A cylindrical rotating roller having a cylindrical shape and a compressed air nozzle for forming a flow of compressed air that intersects the discharge path with respect to the rotating roller are provided. By applying a force that crosses the discharge direction, the bar-shaped object is forced out of the discharge path and sent to the rotating roller, and due to the inertia of the discharge, it moves on the surface of the rotating roller, and the entire rod-shaped object comes into contact with the surface of the rotating roller. Some materials are sandwiched between rotating rollers at a stage and stop advancing in the discharge direction, are turned in a direction that intersects the discharge path, and are transferred to a storage section.

(Problem to be Solved by the Invention) However, in such a conventional pneumatically transported rod-like object receiving device, the direction of the ejected rod-like object is changed in a non-contact state by a flow of compressed air, and the direction of the ejected rod-like object is changed by a rotating roller. It is held in place and decelerated in the direction of release, but
Since the release position of the rod-shaped objects varies slightly in the radial direction, this variation causes subtle changes in the degree of contact of the compressed air to each rod-shaped object, causing posture disturbances such as the rod-shaped object tilting with respect to the rotating roller. This is likely to occur, and the gripping position of the rod-like object is not constant in the axial direction of the rotating roller, and the release position varies slightly.In order to apply compressed air uniformly to all the rod-like objects, it is necessary to adjust the compressed air nozzle. is difficult,
Moreover, it is necessary to provide a means for aligning the rod-like objects that are out of alignment, particularly in the axial direction, in the passage from the rotating roller to the storage section or in the storage section, which poses the problem of not only increasing the size of the entire device but also increasing costs. be.

In view of the conventional situation, the present invention aims to bring a single member into surface contact with a rod-shaped object to change the direction and decelerate the rod-like object in the ejection direction.

(Means for Solving the Problems) The technical means taken by the present invention to achieve the above-mentioned problems consists of a conveyance plane that sandwiches the discharge path of the rod-shaped object and extends substantially parallel to the discharge path; A conical or truncated conical rotating body that rotates toward the storage part is provided, and the central axis of this rotating body is inclined from a position closer to the storage part than the release path toward the rod-like object release direction and the release path side, It is characterized in that the conical surface of the rotating body and the conveying plane are opposed in parallel and separated by approximately the diameter of the rod-shaped object.

(Function) According to the above-mentioned technical means, the ejected rod-like object is held between the conical large-diameter portion of the rotating body and the conveyance plane at a fixed position, and the rod-like object is moved by the rotation of the rotating body. It rolls and turns toward the small diameter portion of the conical surface, and is decelerated in the axial direction due to the difference in circumferential speed between the large diameter portion of the conical surface and the small diameter portion of the conical surface.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

In this embodiment, the rod-shaped object A is a filter plug,
This figure shows the case where the rotating body 5 has a conical shape with an apex angle of approximately 90 degrees, and 20 in FIGS. 7 and 8 is a storage portion such as a hopper in which the filter plug A is stored.

This storage section 20 is a box with a front-to-back length that is approximately equal to the length of the filter plug A. A receiving device 1 is provided on the side of the storage section 20 for receiving and supplying the filter plug A, and below the receiving device 1 is provided a receiving device 1 for receiving and supplying the filter plug A. A dispensing device 21 for dispensing the filter plug A is provided.

The receiving device 1 is connected to the transport pipe 2, and the transport pipe 2
Filter plug A air-fed from
One by one is intermittently received by the receiving roller 31 and the second receiving roller 32, and in the case of this embodiment, it is sent to the storage section 20 via the conveyor 3.

The main parts of the receiving device 1 will be explained with reference to FIGS. 1 to 4. In the figures, 19 is a bottom plate, and on the bottom plate 19, a conical mount 18 and a receiving part mount 17 are arranged in parallel.

A conveying plane 4 is laid on the receiving part mounting base 17 so as to follow the lower surface of the discharge path of the filter plug A discharged from the transport pipe 2, and the conveying plane 4 is
Two notches 4a each having a rectangular plane are provided on the side of the conveyor 3, and the lower belt conveyors 3a, 3a of the transport conveyor 3 are disposed in these notches 4a, 4a.

The lower conveyors 3a, 3a are ordinary conveyors with belts stretched around pulleys, and are installed in a row so as to be flush with the conveyance plane 4.
Upper conveyors 3b, 3b are arranged above 3a with an interval equal to the diameter of the filter plug A.

The upper conveyors 3b, 3b are the lower conveyors 3a, 3a.
The filter plug A is sandwiched and conveyed between upper conveyors 3b, 3b and lower conveyors 3a, 3a.

Further, on the conical mounting base 18, as shown in FIG. 4, a tilting base 16 having an approximately 45° inclination is provided.
A rotating body 5 is rotatably provided on the inclined table 16, and a motor M is arranged in parallel and linked by a belt 21.

The rotating body 5 has its center line inclined so that the conical surface small diameter section B is disposed between the upper conveyors 3b and 3b on the side of the storage section 20 from the discharge path, and the conical surface large diameter section C is disposed between the upper conveyors 3b and 3b.
As it goes to the side, it gradually approaches the discharge direction and discharge path of the fielder plug A, and furthermore, the conical surface and the conveying plane 4 are opposed to each other in substantially parallel.

The distance between the conical surface of the rotating body 5 and the conveying plane 4 is the diameter of the filter plug A or slightly smaller than that, and the rotating body 5 is rotated by the motor M from the discharge path side to the conveyor 3 side. .

Note that reference numeral 15 in FIG. 1 denotes guide plates, which are provided on both sides of the conveyor 3. Although this guide plate 15 prevents the filter plug A from jumping out, it can also be omitted.

The operation of this embodiment will now be explained with reference to FIGS. 5 and 6.

The line segment BC indicates the contact area between the mirror surface of the rotating body 5 and the filter plug A, and in the line segment BC, C is the large diameter part of the conical surface, B is the small diameter part of the conical surface, and when the conical surface rotates, Since the circumferential speed is proportional to its outer diameter, B in the diagram
<C, and the peripheral speed V is divided into a force Va pushing the filter plug A in the axial direction and a force pushing the filter plug A in the radial direction Vb, as shown in FIG.

When the filter plug A is released from the transport pipe 2 in this state, it is first held between the large diameter portion C of the conical surface of the rotary body 5 and the conveyance plane 4, and the rotation of the rotary body 5 causes the filter plug A to be released from the conical surface. The filter plug A is rotated in the axial direction due to the circumferential speed difference between the conical large diameter part C and the conical small diameter part B as it rolls and turns toward the small diameter part B side and is transferred to the small diameter part B side of the conical surface. force to push
Va gradually decreases to 0, and is transferred to the conveyor 3 and transferred to the storage section 20.

Incidentally, the component force Va in the axial direction at the large diameter portion C of the conical surface of the rotating body 5 is set to be slightly smaller than that delivered from the transport pipe 2.

Next, another embodiment of the present invention will be described with reference to FIGS. 9 and 10.

In this embodiment, a long square hole 22 is bored in the conveyance plane 4 in the previous embodiment, and a belt conveyor 20 is disposed in the square hole 22, and the other configurations are the same as those of the previous embodiment and will be explained. is omitted.

The belt conveyor 20 is a conventional one in which a belt 20b is stretched around two pulleys 20a, and is provided from the discharge port of the transport pipe 2 to the upper and lower conveyors 3a and 3b.

According to this belt conveyor 20, the frictional resistance of the conveyance plane is increased, and the filter plug can be easily rotated in the radial direction.

Further, the belt conveyor 20 is driven continuously so that the friction surface that comes into contact with the rod-shaped object A is the belt 20b.
It is made evenly over the entire surface to prevent uneven wear, and is highly durable.

Incidentally, in the description of both of these embodiments, a case has been described in which the rotating body 5 has a conical shape, but it may also have a shape in which the top side of the conical shape is cut off, that is, a truncated conical shape.

(Effects of the Invention) Since the present invention has the above configuration, it has the following advantages.

The ejected rod-shaped object is held between the large-diameter portion of the conical surface of the rotating body and the conveying plane at a fixed position, and as the rotating body rotates, the rod-shaped object rolls toward the small-diameter portion of the conical surface and is turned. Since the speed is reduced in the axial direction due to the difference in circumferential speed between the large diameter portion of the surface and the small diameter portion of the conical surface, direction change and deceleration in the discharge direction can be performed by bringing a single member into surface contact with the rod-shaped object.

Therefore, compared to the conventional method in which the ejected rod-like object is changed direction without contact with compressed air and then clamped by rotating rollers and decelerated in the ejection direction, the ejection position of the rod-like object is slightly uneven in the radial direction. Even if there is a problem, each rod-like object can be transferred to the storage section in a uniform state without any disturbance in its posture, making adjustment work easy, and there is no need to provide a means to align rod-like objects with disordered postures, making the entire device more compact. It is possible and inexpensive.
