Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a package transport tray for inserting a package in a tray and transporting the package to a next process by a conveyor.

[0002]

[Prior art]

 When a package in which a thread is wound around a paper tube is conveyed, the package is inserted into a tray in which pegs are erected and conveyed by a conveyor. In this way, when the packages are conveyed by inserting them on the trays, one tray at a time is required for transfer to various yarn processing devices provided on the conveyor line or other conveyors. When processing is performed by stopping at a predetermined location or when transferring, the stopper is projected from below the rollers of the roller conveyor, and the tray is stopped by projecting the stopper from below the conveyor. Lower it, cut out the next tray, and stop it again with the stopper.

[0003]

[Problems to be solved by the device]

 In this way, when the stoppers are projected from below the conveyor to the front of the trays, the trays in front are stopped when the trays come into contact with each other and are conveyed in order, or when the distance between the trays is narrow. Therefore, when the stopper is projected, the stopper is lowered after the operation is completed, the tray is passed over the stopper, and when the stopper is projected in front of the succeeding tray, it is extremely difficult to project the stopper between both trays accurately. Have difficulty. As a result, the stopper cannot hit the rear part of the front tray or the front of the succeeding tray to push up the tray and stop the tray accurately at a predetermined position. Sometimes the edges were damaged.

Therefore, the present invention surely stops the tray conveyed by the conveyor at a predetermined position by the stopper protruding from the lower side of the conveyor, and the stopper collides with the lower surface of the tray to generate noise, and It is an object of the present invention to provide a package transport tray that is not damaged.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a package transport tray in which a package is inserted, transported by a conveyor, and stopped at a predetermined position by a stopper protruding from below the conveyor, with a notch provided on the outer periphery of the tray. As a result, the tray is securely stopped at a predetermined position, and the stopper does not collide with the lower surface of the tray to generate noise and damage the stopper and the tray.

[0006]

[Action]

 Since the present invention is configured as described above, in order to stop the stopper which is inserted in the package and conveyed by the conveyor at a predetermined position, the stopper protruding from the bottom of the conveyor is such that the trays contact each other on the conveyor. Even when the trays are transported, there is a gap between the trays, into which the stoppers formed by the notches on the outer periphery of the trays are fitted, so that the stoppers project into the gaps without colliding with the trays.

[0007]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, a tray 1 is provided with a standing wall 2, and a peg 3 is provided upright on the front surface thereof to support the package P in a substantially horizontal direction. The tray 1 is formed in a square shape, and notches 7, 8 and 9 extending from the lower surface to the upper surface are provided on the sides 4, 5 and 6 around the outer periphery thereof. A similar notch 10 is also provided on the lower end of the rear surface of the standing wall 3. The peg 3 of the tray 1 is fitted with the hollow hole of the paper tube 12 of the package P, and the package P is erected on the peg 3 and conveyed by the roller conveyor 13.

It is necessary to stop the package P at a predetermined position on the conveyor when performing various kinds of processing or when transferring the package P to another conveyor or a carrying means. Therefore, the stopper 15 is projected from between the rollers of the roller conveyor 13 to stop the tray. At this time, even when the trays 1 that are transported front and back are in contact with each other and are transported, the stopper protruding between the trays is inserted into the stopper insertion gap 14 formed by the notch of the adjacent trays. When opening, make a gap so that it does not come into contact with the bottom of the tray.

As shown in FIG. 3, the stopper 15 is a bifurcated arm formed at one end of a swing arm 18 which is swingably supported around a support shaft 17 supported by a bracket 16. A guide roller 21 at the lower end is fitted to the end portion 20 of the shaft, and can be moved up and down by the swing of the swing arm 18.

The other end of the swing arm 18 has the same structure, and the stopper 25 fixed to the guide roller 23 fitted to the forked arm end 22 can be moved up and down by swinging the swing arm 18. . Both sides of the stopper 25 are guided by guides 26 and can be moved up and down.

A part of the swing arm 18 has a long hole 27, and an eccentric cam 28 fitted in this long hole is rotated by 180 degrees by a motor 29, whereby one end of the swing arm 18 is rotated. The part is raised, and then it is lowered and the other side is raised, and the operation is repeated.

As shown in FIG. 4, the stoppers 15 and 25 can be alternately projected from between the rollers of the roller conveyor 13, and the position of the stopper 15 is an accurate stop position of the tray. When the tray 1 is stopped by the stopper 25, is installed at a position where it can be inserted into the gap 14 formed by the notch on the rear side and the notch of the subsequent tray 31.

Therefore, the arm 18 swings to the position shown in FIG. 4, and the stopper 15 stops the tray 1 at a predetermined position. When it is desired to feed the tray, when the motor 29 is rotated and the eccentric cam 28 is rotated by 180 degrees, the stopper 15 is retracted from the upper surface of the conveyor 13, and the stopper 25 projects instead and is fitted into the gap 14. As a result, the tray 1 is conveyed by the conveyor, and the subsequent tray 31 is stopped by the stopper 25.

When the tray 1 passes above the stopper 15, the motor 29 is rotated to rotate the eccentric cam 28 again by 180 degrees, so that the stopper 25 is pulled in from the upper surface of the conveyor 13 and instead the stopper 15 is rotated. Protrudes. As a result, the tray 1 advances by the conveyor 13 and stops at the position of the protruding stopper 15. At this time, the succeeding tray 31 moves forward together with the front tray to be in the state shown in FIG. After that, the sheets are conveyed while being accurately positioned one by one by the same operation.

In such a conveyor line, as shown in FIG. 5, when being bent and conveyed at a right angle, two belt conveyors 34 and 35 capable of projecting from between the rollers are provided at the corner portion 33, and At the time, it is lowered from the surface of the roller conveyor 13, and when the tray 1 conveyed to the corner section is transferred to the conveyor 13 'side, the belt conveyors 34 and 35 are projected from the surface of the roller conveyor 13, The tray 1 is supported by the belt conveyors 34 and 35, and the tray 1 is transferred to the conveyor 13 'by the driving of the belt conveyor and conveyed. Since the trays are conveyed in this manner, the tray 1, which is conveyed by the conveyor 13 with the leading edge and the trailing edge, has both side edges on the conveyor 13 'and, conversely, has both side edges on the conveyor 13. The part that has been left is conveyed on the conveyor 13 ′ with the leading edge and the trailing edge.

Therefore, similar notches are provided on all four sides of the tray 2 to form stopper insertion grooves regardless of how many times the corner portion 33 is passed and in which direction it is conveyed. To be done.

In the above embodiment, the tray is provided with the standing wall, and the peg is erected on the front surface of the tray to support the package in a substantially horizontal direction to convey the package. The trays may be transported upright, with similar notches on the four sides of the tray.

[0018]

[Effect of device]

 Since the present invention is configured as described above, even if trays are conveyed close to or in contact with each other on the conveyor, a gap for inserting a stopper is formed between both trays, and when the stopper protrudes, Since it is inserted into this gap and does not collide with the tray, the stopper will not lift the tray from the bottom, and the tray can be stopped at the correct position.

Further, since the stopper does not collide with the bottom of the tray or the bottom edge portion of the tray, it is possible to prevent the stopper and the tray from being damaged due to the repetition thereof.
