[0004]

The inventor of the present invention filed a patent application dated May 27, 1991 as a conveyor unit in which the carrying direction of the carrying device L must be changed to a right angle. We provide equipment.

As shown in FIG. 7, the belt conveyor device U comprises a traveling conveyor unit A for feeding in the conveying line direction a and a payout conveyor unit B for feeding in the b direction orthogonal to the a direction. The details are as follows. The traveling conveyor unit A includes a traveling conveyor 1 and a traveling conveyor 2 each having a short and wide width, and a pitch between two pulleys (head side and tail side) is shorter than a width of the pulleys, that is, a belt width. In addition,
Comparing the traveling conveyors 1 and 2, the traveling conveyor 1 is slightly longer. The traveling conveyors 1 are arranged at both ends of the belt conveyor device U, and the traveling conveyors 2 are arranged in the middle. This arrangement is in series along the transport direction a, and there is an interval between the traveling conveyors 1 and 2 for installing a payout conveyor 3 to be described later. The traveling conveyors 1 and 2 are arranged in two rows, and the traveling conveyors 1 and 2 are connected to the motor M1 via the chain 4 and the shaft 5 so that they can be driven in the arrow a direction or the opposite direction. (See FIGS. 8A and 9B).

The payout conveyor unit B is composed of a plurality of payout conveyors 3 each having a long and narrow width, and the payout conveyor units B are arranged in parallel between the traveling conveyors 1 and 2. The pitch of the payout conveyor 3 is long and longer than the width of the traveling conveyor unit A, and the width is narrow and band-shaped. The payout conveyor 3 is connected to a motor M2 via a chain 4 and a shaft 6 and is driven in the direction of arrow b or in the opposite direction (FIG. 8).
(B) and FIG. 9 (A)). The drive direction indicated by the arrow b is a direction orthogonal to the drive direction (a) of the traveling conveyors 1 and 2.

The frame of each payout conveyor 3 has an up-base unit as shown in FIG. 9 (A).
At the position where the payout conveyor 3 is raised, the sheet S can be moved in the direction of arrow b without interfering with the adjacent traveling conveyors 1 and 2 (see FIG. 8 ( See B)). Further, at the position where the payout conveyor 3 is lowered, it does not interfere with the article being conveyed when the adjacent traveling conveyors 1 and 2 are driven (see FIG. 8A).

With the above arrangement, the traveling conveyors 1 and 2 and the payout conveyor 3 are arranged so as to intersect with each other and can be driven without interfering with each other.
The direction can be changed by the belt conveyor device U of one unit, and the conventional belt conveyor system requires the turntable at the contact point of the two belt conveyors, but it is not necessary to provide the turntable. became.

In the belt conveyors 1 and 2 described above, it is necessary to remove and install the belt for the purpose of belt replacement and maintenance inspection due to wear. It is preferable that the property is high.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a mounting structure for a belt conveyor, which facilitates belt replacement work.

[0012]

[Embodiment] Next, an embodiment of the present invention will be described.

FIG. 1 shows the traveling belt conveyor 1 shown in FIG. 7, where (A) is a plan view of essential parts, (B) is a layout of pulleys, and (C) is a side view. The head-side pulley 15 and the tail-side pulley 16 are arranged apart from each other in the feeding direction, and the drive pulley 17 is arranged below them between them. The front of the drive pulley 17 in the feeding direction
Snap pulleys 18 and 19 are arranged at the rear position .
Reference numeral 20 denotes an endless belt, which is the head side pulley 1
5, the tail side pulley 16 and the drive pulley 17 are wound around the outer circumferences of the respective pulleys so that the inner circumference of the belt is in contact, and the snap pulleys 18 and 19 are in contact with the outer circumference of the belt.

Both ends of each pulley are supported by a pair of mounting plates 21. The mounting plate 21 is equipped with a mounting bracket 22 through which bolts 23 are detachably mounted on the square pipe 7 which is a mount. Holes 31 are formed at both ends of the mounting plate 21 (see FIG. 4), and a flange 32 can be fitted into the hole so as to be bolted.
A plate screw 33 can be passed through the center of the (see Fig. 2). The shaft 15a of the head side pulley 15 and the shaft 16a of the tail side pulley 16 are detachably attached to the attachment plate 21 by the flange 32 and the countersunk screw 33 (FIGS. 2 and 1).
(See (C)). The drive pulley 17 is fixed to the mounting plate 21 at a substantially central portion by a flange 34.

The mounting plate 21 has a snap pulley 1 attached thereto.
Position adjusting mechanisms 25 of 8 and 19 are provided and configured as shown in FIG. 1 (C) and FIG. 3. Mounting plate 21
On the shafts 18a, 19a of the snap pulleys 18, 19
A slit 26 for guiding the downward movement is formed, the lower end of the slit 26 is open, and guides 27 are fixed on both sides thereof. Further, the upper portion of the slit 26 is attached brackets 29 for rotatably holding the adjusting board <br/> belt 28, the screw portion of the adjustment bolt 28 axis 18a, 1
It is screwed to 9a.

The adjusting bolt 28 of the position adjusting mechanism 25
Rotating the shaft of the snap pulleys 18, 19
A and 19a can be moved up and down along the guide 27 as shown by an arrow c to adjust the tension of the belt 20. Then, when the adjusting bolt 28 is removed, the snap pulley 1
The shafts 18a and 19a of 8 and 19 are extracted downward from the slits 26 and can be easily removed from the mounting plate 21.

FIG. 4 shows a state in which the mounting structure is separated for maintenance or the like. The mounting plate 21 can be removed from the square pipe 7 which is a pedestal simply by unscrewing the bolt 23. In this case, each pulley 15, 16, 17, 1 on the mounting plate 21
It can be handled as a unit if 8 and 19 are left attached, which is convenient for maintenance and inspection of the frame.

Next, if the bolt 28 is unscrewed, the snap pulleys 18 and 19 can be taken out below the mounting plate 21.
In this case, as shown in FIG. 5, when the snap pulleys 18 and 19 are moved downwards or removed, the belt 20 is loosened into a ring shape, so that the head side pulley 15, the tail side pulley 16 and the drive pulley 17 can be easily removed. The belt 20 can be pulled out. Of course, it is easy to put on the new belt 20. Therefore, the replacement work of the belt 20 and the maintenance of each pulley can be easily performed. Since the head side pulley 15 and the tail side pulley 16 can be taken out from the mounting plate 21 by simply removing the countersunk screw 33, maintenance and inspection of these pulleys 15 and 16 can be easily performed.

FIG. 6 shows the traveling conveyor 2 shown in FIG. Since the traveling conveyor 2 has a shorter span than the traveling conveyor 1, the snap pulley has
Only using (19) pieces. The rest of the configuration is the same as that of the traveling conveyor 1 of FIG. 1. Therefore, also in this traveling conveyor 2, like the traveling conveyor 1, removal from the frame, replacement of the belt 20, each pulley 15, 16, 17,
The maintenance of 19 can be easily performed.

[0020]

[Effects of the Invention] The effects of the present invention are as follows. When the adjustment bolt is rotated, the snap pulley moves up and down.
Can be adjusted to adjust the tension, but in this case, the snap
The pulley is displaced up and down, so wrap it around the drive pulley.
The contact angle of the wrapped belt does not change so much
Since it is kept as it is, a large carrying force is always obtained. For the head side pulley and tail side pulley, remove the countersunk screws.
The flange comes off, so you can easily remove it from the mounting plate.
Also, if you remove the adjustment bolt from the snap pulley,
The shaft of the nap pulley is pulled out from the slit and
Can be easily removed from the plate. Therefore, disassembly and assembly
It is easy and easy for maintenance and inspection. Open the snap pulley downwards from the open slit
When you pull it out, the belt becomes a loose loop,
It is easy to pull out the outer ring in the axial direction of each pulley,
The belt can be easily replaced. Remove the mounting plate from the base simply by loosening the bolts.
In that case, with each pulley attached to the mounting plate,
Good. In this way, it can be handled as a unit, so
Installation work and subsequent maintenance inspection can be performed easily.
