Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor device which is used, for example, to convey a load unloaded at a large number of places in a receiving place by a plurality of conveyor devices and then to join it into one main conveyor. The present invention relates to a conveyor device in which the upstream side is inclined and the lower side is inclined.

[0002]

2. Description of the Related Art Conventionally, for example, large-volume, high-performance sorting /
In the delivery system, when the cargo receiving line at the receiving place is composed of multiple lines, the cargo receiving line is inclined so that the downstream side is higher, and merged with the upper main line,
Therefore, the effective use of the space below each line and the transportation flow lines for bulk and large items are ensured, and simultaneous unloading of these items is made possible to improve the unloading work efficiency. An inclined belt conveyor is used for the load receiving line.

[0003]

According to the above-mentioned conventional type, when a plurality of inclined belt conveyors join the main line, the inclined belt conveyors must be frequently started and stopped for adjusting the timing of the joining. The effect of the time loss will move to the unloading department and reduce the unloading efficiency. In order to solve this problem, a train system in which the slanted belt conveyor is operated in a tact mode to load cargo sequentially, and when the cargo is full on the slanted belt conveyor, the cargo is merged into the main line one line at a time. There is also a method of calling it, but also in this case, the unloading section is stopped until it comes to the merging turn to the line, or an extra storage line is necessary in order not to stop it.

It is an object of the present invention to provide a conveyor device in which the inclined portion can have a front-filling accumulating function and is particularly advantageous for joining a plurality of main lines.

[0005]

In order to achieve the above-mentioned object, a conveyor device of the first invention is a conveyor device which is arranged with the upstream side inclined as a lower part, and comprises a main body frame,
A plurality of idle rollers arranged on the main body frame, a transmission device provided so as to be connectable and separable from the idle rollers, and a drive device interlocked with these transmission devices are provided. In addition to dividing into a plurality of groups in the conveying direction, each group is provided with a braking device that can be freely connected / disconnected to at least one idler roller and a presence detection device. A control device for connecting the braking devices of the upstream group and separating the transmission devices when the presence detection devices of the above are simultaneously detected is provided.

In the conveyor device according to the second aspect of the present invention, the outer circumference of the idler roller is formed as a friction layer. Further, the conveyor device according to the third aspect of the present invention is configured such that a friction member is partially cut off on the outer periphery of the idle roller, and the transmission device and the braking device act on this cutout portion.

[0007]

According to the structure of the first aspect of the present invention, by connecting the transmission device to the idler roller and moving the braking device separately in all the groups, the entire length of the inclined conveyance path is set as the forced rotation area. The luggage can be transported upwards. The cargo carried on the slanted transportation route is detected by the presence detection device every time it passes through each group, but at this time, since the presence detection device in the downstream group is not detected, the control device operates. Instead, the transport form is maintained.

In the state where the package is stopped in the downstream group and detected by the presence detection device, when the package enters the adjacent upstream group and is detected by the presence detection device,
The control device is actuated by the detection movement of the both-side load detection device to separate the transmission device from the idler roller and connect the braking device in the upstream group. As a result, the forced rotation of the idler roller is stopped to make it free, and the idler of at least one idler roller is forcibly stopped so that the load can be stopped in the group on the upstream side, and due to the sliding. It may prevent downward movement.

In the same manner, the next baggage also comes close enough to the baggage in the group on the downstream side and is prevented from moving downward by sliding, and stops in the adjacent group on the upstream side. In this manner, the forward-justified accumulation can be sequentially performed.

When a load is delivered from the downstream side of the inclined transport path, the presence detection device in the downstream group becomes non-detected, thereby connecting and braking the transmission devices in the adjacent upstream group. To move the device apart,
Therefore, the package is forcibly forwarded to the downstream group. Then, the next package can be forwarded to the downstream group in the same manner.

According to the structure of the second aspect of the present invention, the outer circumference of the idler roller is formed in the friction layer, so that the slanted conveyance and front-loading accumulation can be surely performed by the action of preventing slipping on the load.

Further, according to the structure of the third aspect of the present invention, the friction member is laminated on the outer periphery of the idler roller by partially cutting it off, and the transmission device and the braking device are made to act on this cutout part, so that the load The inclined transport and front-loading accumulation can be surely performed by the anti-slip action against, and the friction body can be formed by laminating it on the outer circumference of the idler roller, leaving a portion where the transmission device and the braking device act.

When it does not enter, the transmission device 25 is connected (the air supply hose 55 and the first supply / discharge hose 51 are connected), and the braking device 40 is separated (the supply air hose 55 and the second supply / discharge hose 52 are disconnected). ), The solenoid valve 53 is configured to be switched.

For this purpose, as shown in FIG. 6, a control device 62 in which a photoelectric switch 60 and a control circuit 61 are integrated is provided separately from the solenoid valve 53. The control circuit 61 includes a first transistor 63 that is normally open and that is closed by the detection operation of the optoelectronic switch 60, and a normally closed and optoelectronic switch 60.
The phototransistor 64 and the second transistor 65 which are opened by the detection movement of are incorporated.

A solenoid valve corresponding to the group N at the downstream end
As shown in FIG. 1, only 53 is the first control signal (forced drive signal) from the control section (sequencer) 66 of the main conveyor 80.
Configured to operate with only 70
The phototransistor 64 of the control circuit 61 is connected to the control unit 66 and outputs the downstream end presence detection signal 72 to the control unit 66. A stopper device 69 including a cylinder device 67 and a stopper plate 68 is arranged outside the downstream end of the most downstream group N, and is controlled by the control unit 66.

Next, the transfer work in the above embodiment will be described. In FIG. 9 and FIG. 10, for example, the load 50 unloaded from the truck to the platform 82 is located near the conveyor device 81.
Is transferred by the worker to the upstream end of. And conveyor equipment
The load 50 on 81 is conveyed obliquely upward in the inclined conveyance path 49 by the driving conveyance force of the conveyor device 81, and then merged with the main conveyor 80 from the downstream end thereof and conveyed to the next work place.

Next, the transfer operation of the conveyor device 81 will be described. 1, 3 and 4 show all groups A, B, C ...
At N, the solenoid valve 53 is switched to connect the air supply hose 55 to the first air supply / exhaust hose 51, and the shaft of the air cylinder device 17 is extended to support the shaft.
18 is rocked upward, and all the transmission rollers 21 are pressed against the corresponding idler rollers 28 from below.

At this time, the chain 30 is constantly driven by the motor 34, so that all the sprockets 20 engaged with the chain 30 are rotating around the support shaft 18.
Further, since the transmission roller 21 is in contact with the lower part of the outer periphery of the idler roller 28, the idler roller group 28 is forcibly rotated, so that the load 50 is transported on the inclined transport path 49 having the entire length as the drive area. can do.

At this time, the second supply / discharge hose 52 is opened, the air cylinder device 45 is deactivated, the support shaft 41 is swung downward, and as shown in FIGS. The braking body 44 is separated from the rolling roller 28a. Therefore, no braking action occurs and the corresponding idler roller
28a will be idle when the luggage 50 moves.

The baggage 50 conveyed on the inclined conveyance path 49 as described above is detected by the optoelectronic switch 60 each time it passes through each of the groups A to N-1. At this time, as shown in FIG. Since the optoelectronic switch 60 of the downstream group does not detect and the second transistor 65 remains normally closed, the solenoid valve 53 maintains the connection of the transmission device 25 and the braking device 40.
Is separated, the transport form is maintained.

Then, as shown in FIG. 8, when the package 50 enters the most downstream group N and is detected by the optoelectronic switch 60,
By the detection operation of this optoelectronic switch 60, the first transistor
63 closes. The first control signal 70 from the control unit 66 is the solenoid valve
When the load 50 is not input to the main conveyor 80, that is, when the cargo 50 is not merged with the main conveyor 80, the solenoid valve 53 is separated. At this time, in the group N, the first supply / discharge hose 51 and the air are discharged. Air supply to the cylinder device 17 is stopped and opened, and the support shaft 18 and the like descend by its own weight,
As shown by the phantom line Q in FIG. 3, the transmission roller 21 is an idle roller 28.
Away from.

Air is supplied to the air cylinder device 45 via the second supply / discharge hose 52, and the support shaft 41 is swung upward by the expansion of the air cylinder device 45, as shown by the phantom line O in FIG.
By pressing the braking member 44 against the corresponding idler roller 28a from below, it is possible to prevent the idler roller 28a from idling, whereby the load 50 can be braked and prevented from being conveyed. That is, the idle rollers 28 of the group N are not driven and are freed, and the braking device 40 is operated to forcibly stop the idle rollers 28a from idling, and the luggage 50 is stopped in the group N. It will be.

For example, as shown in FIG. 2, when two packages 50 are accumulated on the downstream side and the two groups N and N-1 are not driven from the downstream side, the next conveyance is performed on the inclined conveyance path 49. It is assumed that the package 50 has been transported. This luggage
50 is sequentially transported from group A to group B.

Then, as shown by the virtual line A, the group N
-3 and the carrying power of group N-2, group N-2
When it is detected by the photoelectric switch 60 of the group N-2, as shown in FIG. 7, in the control device 62 of the group N-2, the first transistor 63 is closed and the photo-electric switch 60 is detected by the detection of the photoelectric switch 60 of the group N-2. Under the condition that the transistor 64 and the second transistor 65 are open, the current from the first transistor 63 of the group N-1 will be blocked by the phototransistor 64 of the group N-2, and thus the electromagnetic field of the group N-2. The valve 53 is operated separately, so that in the same manner as described above, the baggage 50 is group N-1 as shown by the phantom line in FIG.
The vehicle will stop without approaching the luggage 50 and approaching it sufficiently.

As described above, the front-loading accumulation can be sequentially performed, but the merging of the cargo 50 from the downstream end of the inclined transport path 49 to the main conveyor 80 is performed by the control unit 66 according to an instruction. That is, the second control signal 71 from the control unit 66 lowers the stopper plate 68, and the first control signal 70 from the control unit 66 causes the solenoid valve 53 corresponding to the group N.
And the idler rollers 28 of this group N are driven to send out the cargo 50.

By sending out the luggage 50 in this way, the optoelectronic switch 60 of the group N becomes non-detected,
When the detection signal disappears, for example, as shown in FIG.
-1 solenoid valve 53 is connected and the group N-1
The braking device 40 of No. 1 is separated, and the idler rollers 28 of this group N-1 are driven to forward the load 50 to the group N,
You can do forward justification.

In the embodiment of the first invention, each group A to
Although one braking device 40 is provided in N, it is also possible that two or more braking devices 40 are provided in each group A to N.
Although the free rollers 28, 28a made of resin are used, the free rollers 28, 28a made of metal may be used.

Next, an embodiment of the second invention will be described with reference to FIG. That is, a friction layer 90 made of, for example, a rubber lining is formed on the outer periphery of the idler roller 28, and
The anti-slip function of 50 ensures that slanted conveyance and front-loading accumulation are performed. A friction layer 90 is similarly formed on the idler roller 28a corresponding to the braking device 40. Depending on the manufacturing material of the idler rollers 28, 28a, the friction layer 90 can be formed by the surface layer of this manufacturing material.

Next, an embodiment of the third invention will be described with reference to FIG. That is, a friction body 91 made of, for example, a rubber lining is formed on the outer circumference of the idler roller 28. Here, the friction body 91 is not formed in the entire length, and the portion where the transmission roller 21 of the transmission device 25 acts is omitted. Friction body here
The 91 can be formed, for example, by laminating it on the outer circumference of the idler roller 28, leaving a portion where the transmission 25 acts.

As a result, the transmission by the transmission device 25 is eliminated.
The frictional body 91 can prevent the slippage of the load 50, so that the slanted conveyance and the front-loading accumulation can be surely performed. A friction body 91 is similarly formed on the idler roller 28a corresponding to the braking device 40, and the portion where the braking body 44 acts is omitted.
