It can be transported. It is preferable that the conveyor 4 and the rotating belts 1 and 1'are provided in a pair above and below. (See Fig. 4)

In FIG. 1, 9 is a separating means provided with a pressing plate 10. As shown in FIG. 5, the pressing plate 10 is made of a narrow plate member, and the long material A is conveyed in the direction (arrow L direction). In parallel with the above, the frame 11 is vertically inclined and hung vertically. Pressing plate 1

The lower end portion is connected to the elevating cylinder 12 and is vertically movable. The pressing plate 10 is provided so as to incline downward from the upstream side to the downstream side, and the lower end portion abuts the upper surface of the long material A to be conveyed to elastically press the long material A and is conveyed obliquely. One end of the long material A that has been pressed is held and waited until the other end comes into contact with the delay, and the pressing plates 10 are pushed upward by the pressing force of both ends and separated one by one, and the downstream side Be transported to. In this way, the long material A acts to correct the longitudinal direction of the long material A in the direction orthogonal to the conveying direction. The pressing force of the pressing plate 10 is applied by the lifting cylinder 12 and / or the dead weight of the pressing plate 10 to enable elastic pressing.

Two or more pressing plates 10 are required to press both ends of the long material A, and any number of pressing plates 10 can be installed to apply elastic pressing force as needed.
It is preferable that the plurality of pressing plates 10 are arranged side by side on a straight line orthogonal to the conveying direction and are connected by a connecting rod 13 for use. (See Figure 6)

The tip of the pressing plate 10 has a function of pressing the long material A by a proper frictional resistance when the long material A is brought into contact with the front end portion of the pressing plate 10 and holding the long material A at the contact position, or the long material which is in contact with the long material A. A soft material 14 is attached and used for the purpose of not damaging A.

The pressing plate 10 capable of elastic pressing is provided at the end of the conveyor 4 which conveys the long material A in the direction orthogonal to the longitudinal direction. At the terminal end of the conveyor 4, the long materials A are separated one by one by the separating means 9,
It is transferred to the chain conveyor 15 which is continuously provided on the downstream side of.

In FIG. 1, reference numeral 15 denotes a chain conveyor, which is a conveying means for transferring the long material A conveyed from the end portion of the conveyor 4 and conveying it while holding the longitudinal direction in a direction orthogonal to the conveying direction. is there. As shown in FIG. 5, the chain conveyor 15 is provided with partition members 16 for separating and mounting the long materials A one by one at regular intervals.
As shown in FIG. 6, the partition member 16 is sandwiched by mounting members interposed between the two series of chain conveyors, so that the long material A can be stably placed. Partition member 1
The shape of 6 may be any shape such as a circular roll or a polygon as long as it does not deviate from the purpose of stably partitioning the long material A. The outer diameter of the partition member 16 is
Depending on the diameter of the long material A to be conveyed, it is preferably 20 to
100 mm is good. As the material of the partition member, a long material A
A material that is softer than the long material A is preferable so as not to come into contact with and be damaged, but nylon is specifically preferable.

The chain conveyor 15 thus constructed is
Since one long material A is supported and placed by two continuous partitioning members 16, the long material A swings during conveyance and is displaced back and forth, and as a result, the long material A is It is prevented from skewing with respect to the conveying direction or crossing the front and rear long members A ′. The long material A separated from each other and sent out from the conveyor 4 is conveyed to the counting step while maintaining the separated state. The chain conveyor 15 is provided with at least one series 15a and 15b at both ends of the transport path. A conveyor 21 such as an ordinary belt conveyor may be provided between the chain conveyors 15 arranged at both ends of the transport path. (See Figure 9)

The carrying speed of the chain conveyor 15 is preferably 1.1 to 5 times, more preferably 1.5 to 3 times the carrying speed of the conveyor 4. If the transport speed of the chain conveyor 15 is less than 1.1 times the transport speed of the conveyor 4, the chain conveyor 1 moves from the conveyor 4 that is connected and transported.
5, it is difficult to smoothly transfer the long materials A separately one by one, and when the length is 5 times or more, the chain conveyor 15
It becomes difficult to stably convey the long material A onto the partition member 16 provided above.

Instead of the chain conveyor in which the partitioning members 16 are attached at regular intervals, a timing belt 23 having a profile 22 or a conveyor belt 25 having a rotatable roller 24 as shown in FIG. 14 may be used. Good.

In FIG. 1, reference numeral 17 is a sorting rod, which is connected to a vertically moving lifting cylinder 18 as shown in FIG.
It intervenes between the long materials A placed on each other and conveyed separately. After the sorting rod 17 intervenes between the long strips A, the sorting rod 17 is moved to the downstream side in the transport direction by the drive cylinder 19 which reciprocates in the transport direction, and the long strip A sorted by the sorting rod is conveyed by the chain conveyor. It is sent from the terminal end of 15 to the subsequent process. After the delivery, the lifting cylinder 18 is used to sort 1
7 is lowered, and then the sorting rod 17 is returned to the upstream side in the transport direction by the drive cylinder 19 while retracting from the transport path surface. As shown in FIG. 9, the sorting rod 17 is provided with 17a and 17b standing on both ends of the long material A at a position upstream from the terminal end of the transport path by a predetermined distance. The sorting rods 17a and 17b are provided with counting sensors 20a and 20b, respectively.
a receives a signal counting a predetermined number of long materials A to operate the sorting rod 17a, and a counting sensor 20b receives a signal counting a predetermined number of long materials A to operate the sorting rod 17b. ing.

Next, the operation of the long material aligning device described above will be described with reference to FIGS. First,
As shown in FIG. 10, the long materials A stacked in multiple stages are conveyed in the arrow L direction from the starting end of the conveyor 4 in the longitudinal direction at right angles to the conveying direction. The long material A that has been conveyed first comes close to the rotary belt 1 ′ composed of the timing pulley and the timing belt, and the long material A that has been conveyed by being stacked in multiple stages on the conveyor 4 is indicated by the arrow R. The long material A that abuts the belt inclined surface Y ′ that rotates in the direction is pushed back to the upstream side, and the long material A pushed back in the upstream direction and the long material A conveyed from the upstream flow newly merged. In the combined flow, the long members A slide against each other so that the longitudinal directions thereof are parallel to each other, and the long members A that come into contact with the inclined surface Y ′ of the rotary belt 1 ′ do not come into contact with each other. The length A is easily divided into two, and the length A not contacting the inclined surface Y ′ smoothly passes under the parallel surface X ′ of the rotary belt 1 ′ and is conveyed to the downstream side. In this way, the long materials A stacked in multiple stages and conveyed by the conveyor 4 are normally arranged in two stages or less and conveyed to the downstream side.

The long material A conveyed from the rotary belt 1'to the downstream side is next brought close to the rotary belt 1 composed of a timing pulley and a timing belt, and stacked on the conveyor 4 in one or less steps. The long material A is passed downstream of the parallel surface X of the rotary belt 1 and is conveyed downstream, but the long material A stacked and conveyed in two or more stages on the conveyor 4 is indicated by an arrow R. The long material A abutting on the belt inclined surface Y rotating in the direction is pushed back to the upstream side, and the newly joined flow of the long material A pushed back in the upstream direction and the long material A conveyed from the upstream is generated. In the merged flow, the long members A slide against each other so that their longitudinal directions become parallel to each other and come into contact with the inclined surface Y of the rotary belt 1.
The long material A that does not abut is easily divided into two parts, and the long material A that does not abut the inclined surface Y smoothly passes below the parallel surface X of the rotary belt 1 and becomes one step downstream. They are aligned and transported.

The rotating belts 1 and 1'are arranged in series with seven rows of the rotating belts 1 arranged in parallel in the conveying direction and in seven rows of the rotating belts 1 'arranged in parallel in the conveying direction. It is set up. (See Fig. 4)

The belt linear velocity of the rotary belts 1 and 1'is set to three times the velocity of the conveyor 4.

The long materials A aligned by the rotating belt 1 one by one and conveyed to the end portion of the conveyor 4 are brought into contact with and pressed by a pressing plate 10 which can be elastically pressed, and conveyed obliquely. One end of the long material A that has been pushed is pressed by the pressing plate 10, the long material A is held at that position, and the other end waits until it reaches the pressing plate. The long material A slides on the conveyor 4. While pressing one end of the long material A with the pressing plate 10, the delayed other end reaches the pressing plate 10 and the long material A
When the longitudinal direction of the is perpendicular to the conveying direction, the connecting rod 1
A pressing force applied to both ends of the long material A is applied to the pressing plate 10 connected to the three pressing members 10, and the pressing plates 10 are pushed up by the long material A, and the long materials A are separated one by one and are chained from above the conveyor 4. It is transferred onto the conveyor 15 and sent out. (See FIG. 11) In this manner, the long material A obliquely conveyed can be conveyed while being separated one by one while aligning the longitudinal direction in the direction orthogonal to the conveying direction.

The long material A sent out on the chain conveyor 15 is placed on the partition member 16 on the chain conveyor 15 by one.
The books are separated and placed, and the long materials A before and after are transported without being displaced with respect to the transportation direction due to a swing during transportation or intersecting with each other.

The chain conveyor 15 is provided with at least one series 15a and 15b at both ends of the conveying path, and is sorted into both ends of the long material A at a position upstream by a predetermined distance from the end of the conveying path. Rods 17a and 17b are respectively provided upright. (See Fig. 12)

The sorting rod 17a at one end, which is arranged at the end of the chain conveyor 15a, receives a signal from the detection result of the counting sensor 20 that a predetermined number of long members A have been counted, and the lifting cylinder 18a is actuated to rise and intervene on the upstream side of a predetermined number of long members A. (Figure 13 (a)
reference)

Next, the sorting rod 17a is the drive cylinder 1.
9a moves forward to the end of the chain conveyor 15a, and a predetermined number of long materials A are sent from the end of the chain conveyor 15a to a cradle (not shown). (Figure 13 (b)
reference)

The sorting rod 17a, which has finished being sent out, is lowered by the operation of the lifting cylinder 18a, retracts from the surface of the conveying path, and is returned to the upstream side in the conveying direction by the driving cylinder 19a to be restored to the original position. (See Fig. 13 (C) and (D))

The sorting rod 17b provided on the side of the chain conveyor 15b also operates in the same manner as 17a to perform sorting. As described above, in order to accurately count the predetermined number of the long material A that is conveyed while being slightly skewed, the counting sensors 20a and 20b provided at both ends of the conveyance path separately pass the long material A. It is important that the sorting rods 17a and 17b at both ends of the transport path that have received the signals are operated separately.

A predetermined number of long materials A are counted at both ends, and the sorting rods 17a and 17b are actuated to operate the predetermined number of long materials A.
When entering the process of paying out the chain conveyors 15a, 15
b is stopped and waiting for the dispensing process to be completed. The sorting rods 17a and 17b that have finished feeding are lowered by the operation of the elevating cylinders 18a and 18b, retracted from the transport path surface, and returned to the upstream side in the transport direction by the drive cylinders 19a and 19b, and then returned to their original positions. Restore. Sorting rod 17a,
When 17b is restored to its original position, the chain conveyor 1
5a and 15b start moving again, and the above work is repeated thereafter.

The present invention is not limited to the above embodiment, and for example, the rotating belt is not limited to one or two rows in series, and may be three or more rows in series. Further, instead of being connected in series, they may be arranged so as not to overlap in series in the transport direction.
