DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is directed to the direction of straws that are cut into a predetermined length and are sent out vigorously one after another in the same direction. It is about the aligning machine.

[Prior Art] Generally, synthetic resin straws used for beverages, medical purposes, etc. are made by cutting a tubular preform extruded into a predetermined length with a rotary cutter and stored in a predetermined container. And transferred to the next step.

[Problems to be solved by the invention] In this case, the direction of the straw is likely to be divided due to the urging by the cutting of the rotary cutter and the high speed motion of the feeding roller of the cutting straw. It was necessary to line up in the same direction. In addition, depending on the direction of the straw, there are problems that after cutting, the straw falls to a predetermined container and drops, or the end is caught by other straws or equipment and damaged.

The present invention was conceived in order to solve the above-mentioned conventional problems, and its purpose is to enable automatic alignment of straws with a simple structure, and to transfer straws transferred one by one at the final position. The present invention aims to provide a new straw arranging machine capable of simultaneously delivering a large number of straws to the next process.

[Means for Solving the Problems] The feature of the present invention based on the above object is that a plurality of conveyor belts having a narrower width than the straw length in which concave grooves are provided over the entire surface and the entire width are arranged on the same surface at desired intervals. Is placed side by side on a machine base so that the straws can be moved and one side of the machine base where the starting ends of the plurality of conveyor belts are present is provided with a straw feeder of a predetermined length, and the other side Is provided with a collision buffer wall of the straw diagonally positioned with respect to the delivered straw, and an inclined plate located on the conveyor belt from the lower side of the collision buffer wall, and the peripheral surface is provided between the end portions of the conveyor belt. Is provided with a rotating roll with a claw which forms a required scooping angle and which has a plurality of claw members for gathering a plurality of straws supported over a plurality of conveyor belts and sending them to another at regular intervals in the periphery. There is something to do.

[Operation] In the above structure, straws of a predetermined length, for example, straws that are sent out one after another with vigorous force fall onto the inclined surface following the collision buffer wall, and when the straws roll down on the inclined surface. It becomes horizontal and falls on the beginning of the conveyor belt. The straws sequentially delivered by this drop are transferred one by one onto a plurality of conveyor belts. The conveyor belt is installed so that its width is smaller than the length of the straw and runs on the same plane at a small interval. When it enters the groove in the above state, and when it enters at least one groove, the alignment direction is aligned, and it moves together with the conveyor belt toward the end of the conveyor belt.

When the straw reaches the vicinity of the end portion, the rotation direction is the same as that of the conveyor belt, and the claw member of the above-described claw-shaped rotating roll in which the claw portion comes out above the conveyor belt causes the straws that are housed in the recesses One or a plurality of scoops are picked up in the gap and received by the surface of the rotating roll. By this reception, a plurality of straws are brought into a parallel state and are directly sent out to the rear of the conveyor belt.

Further, this invention will be described in detail with reference to examples.

[Embodiment] In the figure, reference numeral 1 is a machine base to which a conveyor belt is attached, and has a storage box 2 for a drive device at one end. Inside the machine base 1, there are three conveyor belts 3,3 and two rotary rollers with claws 4,4 located in the gaps between the end portions of the conveyor belts 3,3 have their claws. It is exposed on the machine surface.

The conveyor belts 3, 3 are those in which a large number of rectangular concave grooves 3a, 3a having a width significantly narrower than the straw length are horizontally provided at regular intervals over the entire width of the conveyor belt, and the surface is formed into a tooth profile. The grooves 3a, 3a are moved along the surface of the machine base and on the same plane, and the positions of the concave grooves 3a, 3a of the respective conveyor belts 3, 3 are aligned on the same straight line as much as possible, and the machine base 1 Are arranged side by side in the longitudinal direction.

Further, the claw rotating rolls 4, 4 have a plurality of claw members 4a, 4a that form a required scooping angle on the peripheral surface and are inclined in the rotation direction at regular intervals in the periphery, and the peripheral surface has the concave groove. 3a, so that it is located slightly above the 3a, the conveyor belt 3,
It is provided in each gap at the end of 3. The inclination angle of the claw member is preferably about 90 ° to 135 ° with respect to the tangent line of the roll peripheral surface from the viewpoint of easy scooping and subsequent feeding.

On one side of the machine base 1 where the starting ends of the conveyor belts 3 and 3 are present, a set of rotating rolls 5 and 5 for straw delivery are provided.
However, it is arranged with its rotating surface facing the machine base side.

On the other side of the machine base 1, as shown in FIG. 1, a straw collision buffer wall 7 that is diagonally positioned with the conveyor belt 3 separated from the straw 6 that has been sent out, and a bottom of the collision buffer wall 7. Is provided with a slant plate 8 located on the conveyor belt from the side, and when the straws 6 which are successively sent out from the rotating rolls 5 and 5 collide with the collision buffer wall 7, kinetic energy is absorbed. Then, it falls on the sloping plate below and is guided by the sloping plate 8 to straddle between the conveyor belts 3 and 3, and most of them are accommodated in the recessed grooves 3a and 3a.

In the figure, 9 is a carrier connected to the machine base 1, and 10 and 10 are guide plates provided on both sides of the entrance of the carrier 9.

In the above structure, when the straws 6 are successively sent out from between the rotating rolls 5 and 5 onto the machine base 1, the straws 6 are
One after another collides with the collision buffer wall 7 and falls on the inclined plate 8, and further rolls the inclined plate 8 to be positioned on the starting ends of the conveyor belts 3, 3 in an orthogonal state.

Since the conveyor belts 3 and 3 are constantly circulating, the straws 6 are immediately accommodated in the recessed grooves 3a and 3a so that the arrangement directions are aligned, and the conveyor belts 3 and 3 move toward the end portion.

When the straw 6 is sent to the vicinity of the terminal end, the claw members 4a, 4a of the claw-equipped rotary rolls 4, 4 which rotate in the same direction as the conveyor belts 3, 3 and whose rotation speed is faster than the belt speed are As if scooping from below, the straws 6 of each groove 3a, 3a are received one after the other from the rear, and the ends of the conveyor belt surface in the state where a plurality of straws 6, 6 aligned in a line are bundled. To the carrier table 9 connected to the machine base 1.

[Advantages of the Invention] As described above, the present invention has the impact buffer wall 7 provided on the machine base with the straw 6 sent from the side of the machine base 1 to the machine base.
Collide with, and drop it onto a plurality of conveyor belts 3,3 arranged in parallel on the surface of the machine base, and put straws 6 in the concave grooves 3a, 3a formed on the surface of the conveyor belts 3,3 so that the arrangement direction is changed. Machines that can be moved to the next position by aligning and further arranging a plurality of straws 6 and 6 on the conveyor belt by bundling the straws 6 and 6 on the conveyor belt by the rotating rolls with claws 4 and 4 arranged between the end portions of the conveyor belts Therefore, the straws sequentially sent out from the rotating rolls are automatically aligned in the direction in which they are sent to the next step, and the straws are prevented from being damaged by the misalignment in the direction in which they are arranged. You can Moreover, since the collision buffer wall 7 is provided obliquely with respect to the straw 6 to be sent out, the straw does not strongly bounce back to the sender side due to the reaction force at the time of collision, and the momentum is killed to convey the inclined plate conveyor. Since it falls to the belt side, there is almost no loss during delivery.

Further, at the terminal end of the conveyor belt, a plurality of straws can be sent together by the rotating roll with the claws, so that there is no stagnation of the straws at the belt end, and the straws can be sent out smoothly.

Moreover, since the machine is constructed by only providing the conveyor belt, the rotating roll with the claws, and the collision buffer wall on the machine base, there is no structural complexity, and no special operation is required.
