Description

[Detailed Description of the Invention] The present invention relates to a telescoping belt conveyor, and more particularly to a telescoping belt conveyor that can automatically extend and contract the belt conveyor.

First, the background of the invention will be explained using FIG. 1.

For example, when the plate material sheared by the plate material processing machine 1 is transported by a roller conveyor or belt conveyor, and the small plate materials are sorted and sorted on the way, they are finely sorted and stacked on a large number of pallet devices 5 of the three-dimensional storage device 3, as shown in the figure. If there is not enough space above the pallet device 5, the only way to do this is to slide the front end of the board that has come off the belt conveyor over the previous stack of boards and push it in, or to push it in the same way using a pusher. Ta.

In this case, there was an inconvenience that the later plate materials would disturb the overlap of the previous stacked plates or cause damage. Furthermore, even if there is sufficient space, vacuum adsorption or magnetic adsorption may not be possible if the board has holes, or non-magnetic materials cannot be adsorbed, and objects that blow air up from below may not be able to do so if the board has holes. There were some inconveniences that made it impossible to apply.

The present invention has been made to solve the above-mentioned disadvantages, and preferred embodiments thereof will be described in detail below based on the drawings.

The telescopic belt conveyor 7 as an embodiment of the present invention is constructed with the rear end of the frame 9 (on the left side in FIGS. 2 and 3) inserted under the tubular conveyor 13 of the sheet material sorting device 11 in the previous stage. It is fixed to the machine base 15 of the plate material sorting device 11 with bolts 17, etc., and the front part is fixed with a bracket 21 etc. to the machine base 19 which is constructed by combining grooved steel or the like and by suitable means such as welding.

The frame body 9 described above has guide rails 23 made of, for example, channel-shaped steel with grooves facing inward at the left and right ends, a connecting crossbeam member 25 at the rear, and a flat plate 29 with an elongated hole 27 at the rear end. A shaft 35 of a roller 33 at the rear end is supported on a slide plate 31 which is attached and comes into contact with this flat plate 29.

Therefore, the elongated hole 27 and the tension bolt 3 described above

It is driven by a piston rod 51 and moved in the front and back direction.

A front end roller 53 is provided near the front end of the slide frame 41, and a bearing bracket 55 protruding from the lower surface of the slide frame 41 has a
The belt 39 from the folding roller 57 to the drive roller described later is provided at a height such that it moves in parallel with the belt 39 from the rear end roller 33 to the front end roller 53 described above.

Further, an electric motor 59 is provided at the lower stage of the machine base 19, and a sprocket 69, which is coaxial with a drive roller 67 provided at the middle stage, is driven and rotated from a sprocket 63 attached to an output shaft 61 of the machine 19 via a chain 65. .

The belt 39 for feeding the material described above is connected to the drive roller 6.
7. The material is circulated around four rollers: the rear end roller 33, the front end roller 53, and the folding roller 57, and the material is transferred from the rear end toward the front end.

In this embodiment, an auxiliary roller 71 is provided at the front shoulder of the plate sorting device 11 between the drive roller 67 and the rear end roller 33 to prevent the belt from touching the machine base 15 of the plate sorting device 11.

Furthermore, the telescoping belt conveyor 7 of this embodiment has the following features:
A detection device 73, which also serves as a stopper, is provided as shown in an enlarged view in FIG.

The detection device 73 is a swinging member that swings around a shaft 79 supported by a bearing 77 provided at a higher position at the front end of the front end roller 53 by means of brackets 75 provided on the left and right sides of the front end of the slide frame 41. The main body is a flat plate 81 as an example, and the flat plate 81
The fourth cylinder is operated by a fluid pressure cylinder 83 horizontally attached to the bracket 75 at the front right end in FIG.
It oscillates between the approximately horizontal and vertical positions shown in the figure.

That is, the sliding block 87 attached to the piston rod 85 of the fluid pressure cylinder 83 changes its position back and forth in the guide groove 89, so that the circular arc link 91 swingably attached to the sliding block 87 moves from the flat plate described above. 81 to occupy two positions.

A shock sensor 93 is provided on a portion of the front surface of the flat plate 81, and when the flat plate 81 receives a shock, it issues an electric signal to the control device.

In addition, in FIG. 2, the fluid pressure cylinder 8 shown above the fluid pressure cylinder 49 is shown long in the front and back direction.
3 shows a portion of a conduit 95 for introducing pressurized fluid.

On the other hand, a fluid pressure cylinder 97 is installed diagonally in the center of the extension front of the telescoping belt conveyor 7 of the three-dimensional storage device 9.
The lower end of the piston rod is provided with an abutment block 99 for the detection device 73 described above.

This abutting block 99 is raised so as not to interfere with the large number of pallet devices 5 installed in the three-dimensional storage device 3 while they are being circulated, and when the movement is finished, it is lowered and placed in front of the extending front of the telescoping belt conveyor 7. It is placed at a height of .

In order to carry the plate material into the palletizing device using the apparatus described in detail above, the desired palletizing device 5
The fluid pressure cylinder 97 of the three-dimensional storage device 3 is positioned in front of the extension of the telescoping belt conveyor 7.
The detection device 73 extends the impact block 99.
It is located at the height of the flat plate 81.

During this time, the telescoping belt conveyor 7 is moved to a flat plate 8 which also serves as a stopper while the slide frame is contracted.
1 is kept vertical.

Therefore, the belt 39, which is driven and circulated by the electric motor 59, transports the plate material as a transfer body from the plate material sorting device 11 toward the three-dimensional storage device 3, and when its tip abuts against the flat plate 81 from behind, the impact is detected by the sensor. 93 detects. The electric motor 59 is stopped based on the detection signal from the sensor 93.

Next, the fluid pressure cylinder 49 is operated to extend the slide frame 41 forward and at the same time change the flat plate 81 to a horizontal state. In this case, the front end roller 53 and the folding roller 57 are connected to the belt 39 in front and behind both rollers.
Since the belt 39 is completely horizontal, the portion of the belt 39 in contact with the plate due to the extension of the slide frame 41 does not undergo any circulation movement.

In this way, the slide frame 41 moves forward while the plate on the belt 39 remains stationary, and the flat plate 81 abuts against the aforesaid abutment block 99, and the operation of the fluid pressure cylinder 49 is stopped by the signal from the shock sensor 93.

In this state, if the circulating belt 39 is moved to bring the front end of the plate material into contact with the abutment block 99 and the slide frame 41 is contracted, the plate material will align its front end with the position regulated by the abutment block 99 and move it to the palletizing device. They are quietly stacked on top of each other and return to their initial state.

As can be understood from the above description of the embodiments, the gist of the present invention is as stated in the claims for utility model registration. A slide frame body is supported in a reciprocating manner on the provided guide rail, and a swinging member is provided at the front end of the slide frame body, which can freely change its position between a substantially vertical state position and a substantially horizontal state position. It is being The swinging member is provided with a sensor, and this sensor is a detection device that detects when the conveyance body transported by the belt conveyor provided on the slide frame 41 comes into contact with the swinging member. It also serves as a detection device for detecting that the slide frame 41 has reached the stop position.

Therefore, according to the present invention, when the swinging member is held in a substantially vertical state and the conveyor is transferred by the belt conveyor provided on the slide frame, the conveyor moves to the front end of the slide frame. It comes into contact with the swinging member at the point where it is detected by a sensor provided on the swinging member. Based on the above detection by the sensor, the slide frame starts moving forward, and the swinging member is placed in a horizontal state. When the swinging member comes into contact with, for example, a stopper at the forward stop position of the slide frame, The mounted sensor detects that the forward stop position has been reached.

By the above-mentioned detection operation of the sensor, the slide frame is moved backward and the transport bodies are sent out, so that even if there is not enough space, the transport bodies can be stacked without damaging them. there is.

Further, in the present invention, a swinging member is provided at the front end of the slide frame so that the position can be changed, and a sensor provided on the swinging member detects that the transport body has reached the front end. Since it also serves as a detection device that detects when the slide frame has reached the forward stop position, it is possible to automatically stop the transfer of the transfer body, start and stop the slide frame forward in a timely manner, and This allows the configuration to be simplified.
