Description

[Detailed Description of the Invention] Technical Field of the Invention This invention relates to a conveying device for an automatic weighing and value labeling machine.

Technical background of the invention and its problems Conventionally, as shown in FIG. 1, a weighing conveyor 3 is provided at one end of a packaging conveyor 2 of an automatic packaging machine 1, and a label "width-adjusting conveyor 4" is placed on one side of this weighing conveyor 3. A press body 6 is movably provided on the other side of the weighing conveyor 3, a guide 7 is provided at one end of the weighing conveyor 3 extending to the rear end of the width-adjusting conveyor 4, and a label is pasted. A press body 8 is movably provided on one side of the conveyor 5, a label issuing machine 9 is provided behind the press body 8, a discharge conveyor 10 is arranged on the other side of the label pasting conveyor 5, and packaging is carried out by the automatic packaging machine 1. Packaged item 1
1 is sent onto the weighing conveyor 3 by the packaging conveyor 2, the weight of the packaged article 11 is measured on this weighing conveyor 3, and the weighing conveyor 3 is moved in the direction of the bold arrow to bring the packaged article 11 into contact with the guide 7. , the press body 6 is moved in a direction perpendicular to the conveyance direction of the weighing conveyor 3 to transfer the packaged items 11 to the width-adjusting conveyor 4, and the packaging items 11 are moved along the guide 7 by the width-adjusting conveyor 4 while being conveyed to the label pasting conveyor. 5, and at this position, the label issued by the label issuing machine 9 is pasted on the packaged object 11, and the pressing body 8 is moved in a direction perpendicular to the conveyance direction of the label pasting conveyor 5, and the packaged object 11 is transferred to the discharge conveyor. 10, there is one in which the packaged articles 11 are discharged by a discharge conveyor 10. In FIG. 1, thick arrows indicate the moving directions of the conveyors 2, 3, 4, 5, and 10, and thin arrows indicate the flow of the objects 11 to be packaged.

Now, the guide 7 is for sending the packaged items 11 to a fixed position on the labeling conveyor 5.
When the weighing conveyor 3 is driven, even after the objects 11 come into contact with the guide 7, they climb up the guide 7 due to the frictional force with the weighing conveyor 2, as shown in FIGS. 2 and 3a. If the object 11 to be packaged is further moved towards the guide 7 by the width shifting conveyor 4 in this state, the object 11 to be packaged will become more and more tilted as shown in FIG. Don't do it.

Purpose of the invention This invention was developed in view of the above points, and the purpose is to provide a conveyance device for an automatic weighing and value tagging machine that can reliably convey the packaged items to the fixed position on the weighing conveyor. .

Means for Solving the Problem This invention arranges a packaging conveyor and a weighing conveyor that rotate in the same direction in a line, sends the items to be packaged onto the weighing conveyor and weighs them at this position, and then the weighing conveyor The object is brought into contact with the guide, and the object to be packaged on the weighing conveyor is transferred by a pressing member to the width-shifting conveyor that is perpendicular to the weighing conveyor.The width-shifting conveyor brings the object to be packed against the guide and sends it to a fixed position on the labeling conveyor. In a device in which a label is attached to a packaged item on a labeling conveyor, the upper part of the packaged item that has come into contact with the guide is held down by a presser section provided on the guide, thereby preventing the packaged item from tilting. , the guide and the width conveyor are configured so that the packaged items can be reliably sent to the correct position on the labeling conveyor.

Embodiment of the invention A first embodiment of the invention will be explained based on FIGS. 4 to 6. Components that are the same as those described in FIGS. 1 to 3 are designated by the same reference numerals, and description thereof will be omitted (the same applies hereinafter). The guide 7 has a length that is greater than or equal to the sum of the width of the weighing conveyor 3 and the length of the width-adjusting conveyor 4, and a presser portion 12 that protrudes in the horizontal direction is integrated into a portion of the guide 7 that faces one end of the weighing conveyor 3. A presser portion 13 is provided at a portion of the guide 7 facing one side of the width-adjusting conveyor 4 and is inclined so as to gradually become lower in the conveying direction of the width-adjusting conveyor 4.

In such a configuration, the weight of the packaged object 11 sent from the packaging conveyor 2 to the center of the weighing conveyor 3 is measured at that position. Thereafter, the object to be packaged 11 is sent by the weighing conveyor 3 and comes into contact with the guide 7, and as the weighing conveyor 3 continues to drive, the object to be packaged 11 climbs up the guide 7, but as shown in FIG. Since the presser portion 12 is formed in the container, the amount of lifting up is small, and when the weighing conveyor 3 is stopped, the items to be packaged 11 return to a horizontal position due to their own weight. Then, the packaged items 11 on the weighing conveyor 3
is transferred to the width-adjusting conveyor 4 by the pressing body 6, and is moved to the label pasting conveyor 5 while being pushed toward the guide 7 by the width-adjusting conveyor 4. On the width-adjusting conveyor 4, as shown in FIG. Even if the object 11 to be packaged is slightly tilted, the angle of inclination is small and the width-shifting force of the width-shifting conveyor 4 is small compared to the conveyance force, so that the object 11 to be packaged is tilted slightly.
1 will not tilt any further. In particular, the presser part 1 is inclined so as to face the side of the width-adjusting conveyor 4.
3, when the article 11 to be packaged is conveyed by the width-adjusting conveyor 4, it is pressed by the presser portion 13 and returned to the horizontal position as shown in FIG. 6b.
Therefore, the position of the packaged object 11 can be accurately determined by the guide 7 and the width-adjusting conveyor 4. The position of the packaged object 11 in the conveyance direction is determined by the feed amount of the label pasting conveyor 5.

Next, a second embodiment of this invention will be explained based on FIGS. 7 and 8. In this embodiment, the guide 7 is provided with a holding part 14 having a length extending from the weighing conveyor 3 to the rear end of the width-adjusting conveyor 4, and the holding part 14 is inclined so that it becomes gradually lower as it goes in the conveyance direction of the width-adjusting conveyor 4. This is what I did.

Therefore, even if the article 11 to be packaged comes into contact with the guide 7 by the weighing conveyor 3 and rises after being weighed, the amount of rise is limited because it is held down by the presser section 14. Then, the object to be packaged 11 is pressed by the inclined presser section 14 while being conveyed by the pressing body 6 and the width-adjusting conveyor 4, and gradually returns to the horizontal state.

Effects of the invention Since this invention is configured as described above, the inclination of the packaged items on the weighing conveyor can be limited to at least a certain range by the holding part, and thereby the packaged items can be returned to the horizontal position and guided. This has the effect of being able to determine the position using the width conveyor and the width conveyor and send it to the labeling conveyor.
