DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transverse transporting device for transporting a transported object such as a grain, and more particularly to a device for detecting the transport of a transported item.

[0002]

2. Description of the Related Art Conventionally, when a traverse transport device is installed at a high position or a number of traverse transport devices are installed such as a large facility, which transport line is currently being transported. In addition, it is extremely labor-intensive for an operator to directly confirm which transport line has completed the transport operation. Therefore, this type of conventional traverse transport device has a sensor for detecting a transported object in the opening of the traverse transport device, and detects the transport of the transported material in the casing of the traverse transport device. There is a type in which a detection plate is suspended from a shaft so as to be swingable in a transport direction.

[0003]

However, among the above-mentioned known examples, the former in which a sensor is mounted in the former opening is used in the case of a conveyed object having a large amount of dust due to the adhesion of the dust or the dust mass in which the dust is solidified. There is a problem that a malfunction occurs. In the latter case, the detector is suspended in the case.
Since the carrier of the conveyor moves on the bottom plate of the machine inside the machine, it does not interfere with the movement of the carrier.
The detection body such as a sensor is provided above the movement trajectory of the upper end of the carrier, and the conveyed material thinly conveyed on the bottom plate that does not reach the movement trajectory of the upper end of the carrier does not contact the detection body, There is a problem that detection is impossible, and it is useless when the transport amount is small. Although not conventionally known, Japanese Patent Application No. 11-282015 has proposed a configuration in which a flow detector is provided at the entrance.
In the prior art, as soon as supply is interrupted,
There is a problem in that it is detected that the conveyance has been completed, and when a plurality of openings are provided, there is a problem in that a flow detector must be provided in each of the openings.

[0004]

It is configured to move by sliding contact.

The supply unit 2 is provided with a transport object detector 31 of a transport object detection device 30 for detecting the transport (flow) of the transport object. That is, an inlet 3 is formed on the upper rear side of the supply unit 2, the supply port 4 is located below the front side of the inlet 3, and the conveyed object detector 31 is located below the inlet 3. Thereby, it is provided on the side plate 33 of the supply unit 2 so as to be rotatable by the horizontal shaft 32 so as to face the flow path into which the conveyed material is introduced. Therefore, when the conveyed material input from the input port 3 falls, the conveyed object detecting body 31 rotates by the weight of the conveyed object detecting body 31 by detecting the load of the conveyed object. Thus, the conveyance (flow) of the conveyed object is detected.

In the embodiment, the conveyed object detector 31 bends both side edges of the trapezoidal plate having a wide rear portion and a narrow front portion so that the conveyed objects flow down while gathering at the front end side. The leading end of the transported object detector 31 is rotated downward even at the beginning, at the end, or when the input amount is small.
Therefore, the leading end of the transported object detection body 31 is narrow,
The base of the conveyed object detector 31 has a width substantially the same as the left and right width of the input port 3 so as to widely receive conveyed objects falling from the input port 3. In addition, not only during loading, but also when a large amount of transported material is loaded, before the transported material gathers at the narrow end of the transported object detection body 31 and flows down, it is rotated by weight and retracted as it is. Therefore, it does not hinder the supply of the conveyed goods.

One end of the horizontal shaft 32 projects laterally from the side plate 33, and a base of an arm 35 constituting a part of the conveyed object detecting device 30 is fixed to the projecting portion. A spring 36 whose one end is locked to the fixed portion of the supply unit 2 is locked at the tip of the arm 35 so that the conveyed object detection body 31 always faces the flow path into which the conveyed object is loaded by the elasticity of the spring 36. Energize. Above the horizontal shaft 32, a guide plate 37 is provided which is inclined so as to be located on the front side as it goes down. The guide plate 37 surrounds the upper part of the shaft mounting portion of the horizontal shaft 32 and a spring 36
The conveyance object detector 31 is made to stand by at a predetermined angle by contacting the upper surface of the conveyance object detector 31 urged by the above.

A detection member 40 such as a limit switch is provided in the rotation path of the arm 35, and detects that the conveyed object has caused the conveyed object detector 31 to rotate. Detection member 4 of embodiment
Numeral 0 denotes a limit switch 41, and the operating rod 42 of the limit switch 41 faces the rotation trajectory line of the arm 35. When the arm 35 is rotated by the conveyed object detector 31, the operating rod 42 contacts the operating rod 42. Reference numeral 43 denotes an adjustment bolt which adjusts the elasticity of the spring 36 to detect the transported object 31
The weight of the conveyed object at which the rotation starts is adjusted and set. Reference numeral 44 denotes an openable and closable inspection window provided on the side plate 33 of the supply unit 2, and is preferably formed of a transparent member so that the inside can be visually recognized. Reference numeral 45 denotes a mounting stay on which the detection member 40 is mounted.

Thus, the conveyed object detecting device 30 can detect the flow of the conveyed object by the conveyed object detecting body 31 and the detecting member 40 and determine whether or not the conveyer 7 is being conveyed. It is connected to a display device provided in one or both of the operation rooms, and displays the detection result of the transferred object detection device 30. A motor 4 for rotating the driving sprocket 10
6 and automatically turn on and off. in this case,
When a predetermined time elapses after the conveyance object detecting device 30 detects that the conveyance of the conveyance object is stopped, the conveyance conveyor 7 conveys all the conveyance objects.
May be automatically stopped. In addition, when a plurality of discharge units 6 are provided, it is preferable that the time set by the timer can be changed according to the position of the discharge unit 6 to be used, so that it is possible to easily cope with it.

[0016]

[Operation] Next, the operation will be described. When the motor 46 is energized, the drive sprocket 10 rotates, and the drive sprocket 10 rotates the chain 13 to move the carrier 12 from the start end to the end of the casing 1. In this state, when a conveyed object is supplied to the input port 3 of the supply unit 2, the conveyed object enters the casing 1 from the supply port 4, and is conveyed toward the end along the bottom plate 26 by the moving conveyance body 12. You. However, in this state, although the driving sprocket 10 is rotating, it is difficult to determine whether or not the conveyed material is being conveyed by the conveyer 7 from outside the machine housing 1.

However, the transported object detector 31 is provided in the supply unit 2.
Is rotatably provided by the horizontal axis 32 so as to face the flow path into which the conveyed material is introduced. Therefore, the conveyed material input from the input port 3 reaches the conveyed object detection body 31 and 31
The conveyed object detector 31 drops down from the narrow portion at the front end of the conveyed object detector 31 into the supply port 4.

Due to the weight of the conveyed object flowing down on the conveyed object detection body 31, the conveyed object detection body 31 rotates downward about the horizontal axis 32 against the elasticity of the spring 36, and the horizontal axis 32 The rotation of the arm 35 causes the arm 35 to rotate, and when the arm 35 rotates, the detection member 40 detects the rotation, and the transported object detection device 30 detects that the transported object has been loaded into the supply unit 2. Therefore, while the detection member 40 is detecting the loading of the transported material, the transport conveyor 7 is transporting the transported material,
Thereby, the conveyance of the conveyor 7 is detected.

In this case, the detection of the loading of the conveyed object by the conveyed object detecting device 30 may be any weight as long as the conveyed object detector 31 can be rotated. The detection member 40 rotates and detects this. Therefore, even if the transport amount is small, the transport by the transport conveyor 7 is detected.

In addition, even if the conveyed material contains a large amount of dust, the detection member 40 is provided outside the supply unit 2, so that the detection member 40 is not affected by the dust, thereby preventing malfunction. Further, since the transported object detecting device 30 is provided in the supply unit 2, the malfunction due to dust clumps is less than in the case where the transported object detecting device 30 is provided at the end of the machine housing 1.

Further, even if the supply is temporarily interrupted and the conveyed object detecting device 30 is in the non-detection state, and once the conveyance is detected to be completed, if the supply is resumed, the conveyed object detecting device 30 is again detected.
Since 0 indicates the conveyance of the conveyed object, the conveyance of the conveyor 7 can be displayed. Therefore, when the supply is restarted, the conveyed object detecting device 30 always detects the conveyed object, so that the automatic control of the on / off of the motor 46 can be easily performed.

Since the conveyor 7 always conveys a conveyed object while the conveyed object detection device 30 detects the input of the conveyed object, the supply unit 2 of the machine housing 1 and the end of the end of the conveyed object are dropped. 5
Are provided between them, and even if it is not clear from which discharge unit 6 the paper is discharged, the conveyance by the conveyor 7 can be detected. Therefore, the conveyance object detection device 30 may be provided at one position in the supply unit 2, and the cost is reduced.

When the conveyed object detecting device 30 is connected to a display device provided at an arbitrary predetermined position, the conveyed object detecting device 30 indicates that the conveyed object is flowing in the machine housing 1. For example, when the detection member 40 is connected to the display panel of the operation room, the display lamp of the lateral transport device in the operation room can be turned on to indicate that a conveyed object is flowing in the machine housing 1.

When the loading of the conveyed article into the supply section 2 is completed, the conveyed article detecting body 31 automatically returns due to the tension of the spring 36, while the detecting member 40 detects the completion of the conveyed article. Therefore, when a signal is sent to the display panel of the operation room in consideration of the transfer time by the transfer conveyor 7, the completion of transfer of the transfer conveyor 7 can be displayed.

As described above, the transported object detecting device 3
0, the presence or absence of the loading of the conveyed object is detected, and based on this, if the effect is displayed at any place (including any display means such as voice), the operator / operator can use any of the lateral feeding conveyance. You can instantly determine if the device is working.

In the above case, while the conveyed object detecting device 30 is detecting the loading of the conveyed object, the conveyor 7 is conveying the conveyed object, and the conveyed object detecting device 30 sets the conveyed object in the non-detection state. When the predetermined time required for the conveyance by the conveyance conveyor 7 has elapsed, the conveyance is completed. Therefore, the conveyance conveyor 7 is automatically stopped when the predetermined time elapses after the conveyance object detection device 30 detects the stop of the supply of the conveyance object. . Therefore, operability is improved.

Further, if the conveyor 7 is started before loading the conveyed goods, not only stop but also start,
Since the operation can be automated and the transport state can be reliably detected, the automatic control becomes easy.

As described above, the conveyed object detection device 30 may be provided in the supply unit 2 to reduce the cost. However, this does not mean that the conveyed object detection device 30 is provided in the discharge unit 6. The detection device 30 may be provided and used in combination, and when used together, the conveyance state of the conveyed object can be more accurately grasped, and the timer may not be required in some cases.
