When the restricting storage parts 12 are moved to the carrying direction in such a state, vibration is granted to the restricting storage parts 12 by the vibrator 20 and the materials to be carried are aligned in the almost perpendicular direction of carrying by the vibration, so that the materials are carried, while being aligned in predetermined number, with the carrying ability of a belt conveyor.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transporting device for transporting a substantially bar-shaped conveyed object, and more particularly, to a substantially bar-shaped conveyed object such as a bar-shaped part such as a nail or a bar-shaped food such as a sausage. The present invention relates to a transport device that transports while aligning the paper.

[0002]

2. Description of the Related Art In general, a belt conveyor is widely known as a transport device. This belt conveyor can convey objects at a constant speed, but since it only conveys objects while being supplied on the conveyor belt, it is a rod-like shape that is entangled like a nail. Cannot be transported while aligning the transported object in a predetermined direction. For this reason, conventionally, a part feeder is known as a transport device that transports a rod-shaped transport object such as a nail while aligning the transport object in a predetermined direction. The parts feeder is configured to separate the entangled conveyed objects by the vibration of the vibrator and to move the conveyed objects along a spiral tray so as to convey the conveyed objects while aligning the directions of the conveyed objects.

[0003]

However, such a parts feeder is a mechanism for conveying a bar-shaped object to be conveyed by vibrating the vibrator. Therefore, there is a problem that the conveying speed is very slow as compared with a belt conveyor. . Also,
In this parts feeder, the bar-shaped transported object moves along the spiral tray, so that the bar-shaped transported object can be aligned in the transport direction, but the transported object is continuously oriented in the transport direction. Therefore, there is a problem that the objects to be conveyed cannot be collectively conveyed in a bundle state by a predetermined amount, and thus the objects to be conveyed cannot be collectively taken out by a predetermined amount at a time.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a belt conveyor having a carrying ability and to be able to carry a substantially bar-shaped object while aligning the object by a predetermined amount.

[0005]

A transport device according to the present invention comprises:
An endless annular belt wrapped around and circulated between two belt wheels accommodates a substantially rod-shaped object to be conveyed by a predetermined amount, and a regulating housing portion for regulating the direction of the object to be conveyed in a direction orthogonal to the conveying direction. A conveyor means arranged sequentially along the circulation direction, and a vibration imparting means for imparting vibration to the regulation accommodating portion. According to the invention,
When a substantially rod-shaped conveyed object is accommodated in the regulating accommodating portion arranged on the belt of the conveyor means by a predetermined amount, the accommodated conveyed object is regulated by the regulating accommodating portion in a direction orthogonal to the transport direction, Many of the accommodated transported objects will be aligned in a direction substantially orthogonal to the transport direction, and in this state, when the regulating storage section moves in the transport direction by the belt, the vibration applying means Vibration is applied, so that a predetermined amount of conveyed objects accommodated in the regulation accommodating section are all aligned in a direction substantially orthogonal to the conveyance direction by the vibration of the vibration applying means, thereby providing the conveyance capacity of the belt conveyor. In addition, it is possible to convey a substantially bar-shaped object while aligning it by a predetermined amount.

[0006] In this case, as described in claim 2, the regulation accommodating portions sequentially arranged on the belt along a circulating direction of the belt are provided on the belt at a pitch longer than a longitudinal length of the conveyed object. By comprising a plurality of support members erected in the, and a sheet member stretched in a substantially arcuate shape between each of the plurality of support members,
The transported object can be reliably received and accommodated in the regulation storage portion, and when the transported object is accommodated, the transported object moves toward the bottom along the arc-shaped curve of the sheet member. Thereby, the direction of the transported object is regulated, so that most of the transported objects can be aligned in a direction substantially orthogonal to the transport direction at the time of storage. According to a third aspect of the present invention, since the vibration applying means is a vibrator attached to the conveyor means, the vibration generated by the vibrator is transmitted to the regulation accommodating portion of the conveyor means. Thereby, the transported object can be surely aligned in a direction substantially orthogonal to the transport direction.

The upper surface of the belt 11 substantially corresponds to the length between the belt wheels 9 and 10, and the upper surface thereof is disposed in contact with the lower surface of the belt 11 located on the upper side. Also, on the lower surface of the vibration applying plate 19,
A vibrator 20 is attached. The vibrator 20 is for applying vibration to the transferred object 5 conveyed by the conveyor mechanism 6 and includes a vibrator main body 21.
And a vibrating plate 22. The vibrating plate 22 is attached to the vibration applying plate 19, and the front and rear portions of the vibrating plate 22 and the front and rear portions of the vibrator body 21 are respectively inclined at a predetermined angle.
In this state, an alternating magnetic field is generated in the electromagnetic coil 24 embedded in the rear part of the vibrator body 21, and the alternating magnetic field
2 is configured to be quickly separated by suction and vibrated.

By the way, behind the conveyor mechanism 6, as shown in FIG. 2, a supply device 25 for supplying the transported object 5 is arranged. The supply device 25 includes the vibrator 2
6 and a supply trough 27, and the vibrator 26
A coil spring 29 on a mounting table 28 provided on the base 1.
It is configured to be arranged via. In this case, the vibrator 26 has the same configuration as the vibrator 20 of the conveyor mechanism 6 and includes a vibrator main body 21 and a vibration plate 22, and the front and rear portions of the vibration plate 22 and the front and rear portions of the vibrator main body 21 are respectively inclined at predetermined angles. An alternating magnetic field is generated in an electromagnetic coil 24 which is connected by a spring 23 and is embedded in the rear portion of the vibrator body 21 in this state, and the diaphragm 22 is vibrated via the leaf spring 23 by the alternating magnetic field. . The supply trough 27 is mounted on the vibration plate 22 of the vibrator 26, and the leading end of the supply trough 27 is located at the upper rear portion of the conveyor mechanism 6.
Is arranged close to the upper part of the vibrator 2 in this state.
The transported object 5 is moved in response to the vibration of the upper part 6 so that the transported object 5 is located at the upper rear regulating accommodation part 1.
2 is provided.

In this case, as shown in FIG. 2, the supply operation of the supply device 25 is controlled based on a detection signal from a weight sensor 30 for detecting the vertical movement of the movable platen 2 on which the conveyor mechanism 6 is mounted. ing. That is, the movable platen 2
As described above, since it is supported by the plate spring 3 and the coil spring 4 on the base 1, it has a weighing function. To move up and down. The weight sensor 30 includes the movable platen 2
2 is detected as a supply amount of the transported object 5, and includes a coil bobbin 31 and a ferrite core 32, and the coil bobbin 31 is fixed on the base 1 as shown in FIGS. The ferrite core 32 is mounted on a mounting arm 33 provided on the movable platen 2. In this state, the ferrite core 32 is disposed in a non-contact state in the hollow portion 31 a of the coil bobbin 31, and the vertical displacement of the ferrite core 32 is The coil bobbin 31 is configured to output a detection signal according to the amount.

Next, the operation of such a transport device will be described. First, in the state before the conveyor mechanism 6 conveys the conveyed object 5, since the conveyed object 5 is not supplied to each of the restriction accommodating portions 12, the ferrite core 3 of the weight sensor 30 is not supplied.
2 is located at the upper part in the hollow portion 31a of the coil bobbin 31. In this case, the vibrator 26 of the supply device 25 starts operating based on the detection signal from the weight sensor 30, and the vibration of the vibrator 26 causes the supply trough 2 to move.
7 supplies the bar-shaped conveyed object 5 to the regulation housing portion 12 at the upper rear portion of the conveyor mechanism 6. Then, the movable platen 2 descends against the spring force of the coil spring 4 in accordance with the supplied weight of the transported object 5, and the ferrite core 32 of the weight sensor 30 moves through the hollow portion 31a of the coil bobbin 31 accordingly. Displaces downward. In this way, when a predetermined amount of the transported object 5 is supplied to the regulation housing portion 12, the ferrite core 32 is displaced downward according to its weight, and the coil bobbin 31 outputs a detection signal according to the amount of displacement. Then, based on the detection signal, the vibrator 26 of the supply device 25 is stopped, and the supply of the transported object 5 by the supply trough 27 is temporarily stopped. By repeating this operation sequentially, a predetermined amount of the transported object 5 is sequentially supplied to each of the regulation storage sections 12.

At this time, the belt wheel 10 at the rear of the conveyor mechanism 6 is driven by a motor (not shown), and the endless annular belt 11 circulates between the front and rear belt wheels 9 and 10, thereby providing the belt 11. Each restricted accommodation part 1
2 sequentially moves in the arrow X direction shown in FIG. In this case, the rear belt wheel 10 may be continuously rotated to move each of the regulation accommodating portions 12 continuously at a constant speed, and the weight sensor may be provided each time the conveyed object 5 is supplied by a predetermined amount. 30
The intermittent rotation of the rear belt wheel 10 based on the detection signal from the control unit may control the intermittent movement of each of the regulation storage units 12. In any case, since the interval between the support members 13 of the regulation accommodating portion 12 is provided at a pitch longer than the length of the bar-shaped transported object 5 in the longitudinal direction, a predetermined amount of the transported object 5 is provided. Can be reliably supplied into each of the regulation housing sections 12.

In this manner, when a predetermined amount of the article 5 to be transported is supplied from the supply device 25 to the regulation housing section 12 of the conveyor mechanism 6, the sheet member 14 of the regulation housing section 12 is formed in an arcuate shape. Since there is a transported object 5
Is received by the curved surface of the sheet member 14, and moves toward the bottom along the curved surface. At this time, the direction of the bar-shaped object 5 is regulated, and the predetermined amount supplied by the Most of the conveyed objects 5 are aligned in a direction (arrow Y direction in FIG. 6) substantially perpendicular to the conveying direction (arrow X direction in FIG. 6) as shown on the right end side in FIG. Also,
At this time, since the sheet member 14 of the regulation storage unit 12 is formed of a flexible synthetic resin having elasticity such as urethane resin, even if the transported object 5 falls into the regulation storage unit 12 from the supply device 25, The transported object 5 by the sheet member 14
Can be absorbed to some extent, thereby reducing the noise caused by the fall, and furthermore, the transported object 5 is not damaged, and the transported object 5 can be received and stored satisfactorily. In this case, since the leading end of the supply trough 27 of the supply device 25 is close to the upper side of the support member 13 of the regulation accommodating section 12, the falling height of the transported object 5 can be minimized, and Since the transported object 5 rarely falls directly to the bottom of the regulation housing portion 12 and often comes into contact with the curved side surface of the sheet member 14, the rod-shaped transported object 5 such as a nail is not damaged by these, and the noise is reduced. Can also be reduced.

As shown in FIG. 2, the vibrator 20 provided in the conveyor mechanism 6 operates when each of the regulation accommodating sections 12 accommodating the article 5 to be conveyed is moved by the belt 11 in the conveying direction. Since the vibration generated by the vibrator 20 is transmitted to the belt 11 via the vibration applying plate 19, and the vibration is transmitted to each of the regulation housing portions 12,
As shown in FIG. 6, the object 5 can be reliably aligned in a direction substantially perpendicular to the transport direction by the vibration. As shown in FIGS. 1 to 3, when each of the regulation accommodating portions 12 moves in the transport direction while being subjected to the vibration, the step between the low portion and the high portion of the belt 11 at both ends is reduced.
Since the sheet member 14 is formed to have substantially the same size as the thickness of the sheet member 14, the transported object located at the lowermost position among the rod-shaped transported objects 5 such as nails accommodated in the regulating Even if the leading end of the member 5 moves toward the guide plate 15 during the movement, the object 5 can be satisfactorily conveyed without being caught between the sheet member 14 and the guide plate 15.

In such a transport device, as shown in FIG. 2, the regulating housing 1 moved to the front end (the left end in FIG. 2).
Since the second sheet member 14 is opened so as to extend, it is possible to collectively take out a predetermined amount of the conveyed objects 5 aligned in a direction substantially perpendicular to the conveying direction at a time, thereby facilitating subsequent product inspection. Can be. For example, a predetermined amount of the conveyed object 5 sent out from the regulation accommodating portion 12 at the front end can be arranged on a belt conveyor for inspection and easily inspected by an inspection device such as an inspection camera. At this time, for example, in the case of the transported object 5 having a head such as a nail, the direction of the head can also be aligned. That is,
By detecting the position of the head of the transferred object 5 with an inspection device such as an inspection camera, the transferred object 5 whose head is positioned in a certain direction is transferred as it is, and the transferred object whose head is positioned in a different direction from the transferred object 5 is detected. By automatically taking out the object 5 from the inspection belt conveyor and reversing the direction of the object 5, the head of the object 5 can be easily aligned.

In the above embodiment, the conveyor mechanism 6
Has a configuration in which the sheet member 14 is stretched between the support members 13 in a shape that is curved in an arc shape, but is not limited thereto. For example, the sheet member may be formed in a V-shape or a U-shape. In other words, any shape or structure may be used as long as it can regulate the object to be conveyed in a direction perpendicular to the conveying direction. Further, in the above embodiment, as the vibration applying means,
The case where the vibrator 20 is used has been described. However, the present invention is not limited to this. For example, by controlling the forward and reverse rotations of the motor in a short time, the belt 11 wound around the belt wheels 9 and 10 and the belt 11 are provided. Vibration may be imparted by slightly reciprocating each of the regulated accommodation sections 12. Further, in the above-described embodiment, the transported object 5 is accommodated in the regulating accommodation section 12 by a predetermined amount and transported. However, the predetermined amount referred to here does not necessarily need to be plural, but may be one. The transferred object 5 does not need to be a rod-shaped part such as a nail, but may be a rod-shaped precision part such as a shaft of a precision machine or a bar-shaped food such as sausage. Something like that is fine.

[0020]

As described above, according to the present invention, when a substantially rod-shaped object to be conveyed is accommodated by a predetermined amount in the regulating accommodating portion arranged on the belt of the conveyor means, the accommodated object is conveyed. Is regulated in the direction perpendicular to the transport direction by the regulating container, so that most of the accommodated objects can be aligned in the direction substantially perpendicular to the transport direction. In this state, the regulating container is moved in the transport direction by the belt. When moving toward the direction, the vibration applying means applies vibration to the regulation housing portion, so that all of the predetermined amount of conveyed objects accommodated in the regulation housing portion are substantially orthogonal to the transport direction due to the vibration of the vibration applying means. Thus, it is possible to transport the substantially bar-shaped objects while aligning them by a predetermined amount.

In this case, a plurality of support members erected on the belt at a pitch longer than the longitudinal length of the article to be transported, and a plurality of regulating storage sections sequentially arranged on the belt along the direction of circulation thereof, By being comprised of a sheet member stretched in a substantially arcuate shape between the plurality of support members, the transported object can be reliably received and accommodated in the regulation storage section, and the transported object can be stored. The object to be conveyed moves toward the bottom thereof along the arc-shaped curve of the sheet member when stored, so that the direction of the object to be conveyed is regulated. They can be aligned in orthogonal directions. In addition, since the vibration applying means is a vibrator attached to the conveyor means, the vibration generated by the vibrator is transmitted to the regulating accommodating portion of the conveyor means. It can be surely aligned in the direction.
