Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for equally distributing a large quantity of articles in an aligned state.

[0002]

[Prior art]

 Goods produced in large quantities are eventually distributed and transported in some way. For example, frozen foods that are manufactured continuously are distributed in equal amounts in order to put them in trays in specified amounts, or packed or packed in boxes for transportation. Be transported to.

In the case of equidistantly arranging a large number of these products, if the work is to be performed by only one process line, the product transfer speed and the function of the downstream device cannot be processed at high speed. Therefore, in the past, distribution work was performed in parallel on multiple processing lines to reduce processing time and automate the process.

In this case, if there is an imbalance in the work flow in a plurality of processing lines, the time schedule is affected and the yield of distribution is deteriorated. Therefore, it is possible to balance the flow speed of each line. You will need it.

[Problems to be solved by the device]

 Conventionally, as a method of arranging a large number of articles in a uniform arrangement, as shown in FIG. 5, a swinging distribution bar 32 is provided on an aligning conveyor 31 and a large number of articles A carried out from a supply conveyor 33 are provided. A method in which the articles are distributed by the distribution bar 32 and fed between the guides 34. As shown in FIG. 6, the supply conveyor 42 is swingably provided with respect to the alignment conveyor 41, and the articles A are distributed by the swing of the supply conveyor 42. Then, it is supplied to the alignment conveyor 41.

However, in each of the above-mentioned conventional methods, each article A is simply supplied to the alignment tables 31 and 41 without directivity, so that the sorting is performed with coarse accuracy and each guide is provided. There is a problem that an equal amount of articles cannot be accurately distributed to the guides 34 and 43.

Further, since the articles A are supplied to the upstream side of the guides 34 and 43 of the alignment table in a non-uniform state, the intervals of the articles A aligned between the guides become unbalanced, and the downstream side. There is a problem that it causes inconvenience in the work such as box packaging.

Therefore, an object of the present invention is to solve the above-mentioned problems and to provide a device capable of continuously and accurately arranging a large number of articles while equally arranging them.

[0009]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention attaches a second conveyor whose transport direction is orthogonal to the first conveyor to the transport outlet of the first conveyor that expands and contracts in the transport direction, and transports the second conveyor. The speed was set higher than the transfer speed of the first conveyor.

In the above structure, the transport outlet of the second conveyor faces the alignment conveyor having the same transport direction as that of the second conveyor, and the alignment conveyor has a predetermined direction in the transport direction of the first conveyor. It is possible to provide a plurality of guide guides arranged at intervals of.

[0011]

[Action]

 In the above structure, the articles conveyed by the first conveyor are conveyed by the second conveyor in the direction orthogonal to each other and sent out. In this case, by increasing the conveying speed of the second conveyor more than that of the first conveyor, the articles conveyed by the first conveyor can be arranged on the second conveyor in a state in which they are aligned at intervals substantially equal to one row.

Further, in the above-described carrying state, when the first conveyor is expanded and contracted at a constant time interval, articles can be delivered from the second conveyor in a substantially constant quantity.

【Example】

 An embodiment of the present invention will be described below with reference to the attached FIGS. In the figure, reference numeral 1 is a first conveyor that can be expanded and contracted in the carrying direction, and is commonly called a shuttle conveyor. The first conveyor 1 is provided with a conveyor belt 4 stretched between a plurality of rotating rollers 6 and 7 and a driving roller 8. The conveyor belt 4 includes the rotating rollers 6 and 7 and a driving roller 8. It circulates between 8 and rotates.

The driving roller 8 is connected to a motor 9, and when the driving roller 8 is rotated by the operation of the motor 9, the conveyor belt 4 is rotated to convey the article in the direction of arrow a in FIG. Is set to.

Three of the rotating rollers 6 and 7 are attached to a slide table 11 that slides on the upper surface of the base 10. The slide table 11 has linear guides 12, 12 attached on both sides of the lower surface slidably fitted to guide rails 13, 13 on the upper surface of the base 10, and rack teeth 14 attached to the center of the lower surface of the table 11. In addition, the pinion 15 is engaged. The pinion 15 is connected to a motor 16, and when the motor 16 operates, the slide table 11 slides in the carrying direction (direction a) due to the meshing of the pinion 15 and the rack teeth 14.

In the above-mentioned first conveyor 1, when the slide table 11 slides, the rotating roller 6 attached to the slide table 11 moves between the position shown by the solid line in FIG. 2 and the position shown by the chain line, By the guide of the rotating roller 6, the conveyor surface 4a above the conveyor belt 4 expands and contracts in the conveyor conveying direction.

On the other hand, an inclined plate 17 is attached to the transfer outlet of the first conveyor 1, and a second conveyor 2 is provided below the inclined plate 17. The second conveyor 2 is provided with a pair of rollers 18 installed on the upper surface of the slide table 11, a conveyor belt 5 that rotates between a pair of rollers 18, and a drive motor 19 connected to one of the rollers 18. When the drive motor 18 is operated, the conveyor belt 5 is rotated in the direction orthogonal to the transport direction of the first conveyor 1 (direction of arrow b in FIG. 1).

In this case, the motor 19 of the second conveyor 2 and the motor 9 of the first conveyor 1 each have a speed varying mechanism, and are formed so that the driving speed of the belts can be arbitrarily changed. There is.

An inclined plate 20 is attached to the transfer outlet of the second conveyor 2, and an alignment conveyor 3 is provided below the inclined plate 20 via an inclined chute plate 21.

The equidistant alignment device of this embodiment has the above-mentioned structure, and its operation will be described below. When carrying out the work of distributing the articles, the conveyor belts 4 and 5 of the first conveyor 1 and the second conveyor 2 are both rotated, and the belt 5 of the second conveyor 2 is more than the belt 4 of the first conveyor 1. Rotate fast and set so that there is a difference in transport speed.

In this state, when the articles A are continuously supplied from the chute plate 27 onto the first conveyor 1 as shown in FIG. 4, the articles A are irregularly arranged and conveyed on the first conveyor 1. However, since the article A is conveyed to the second conveyor 2 at a high conveyance speed in the directions orthogonal to each other when it is delivered to the second conveyor 2, the articles A are conveyed in one direction in a substantially lined state due to the difference in speed. It will be. In this case, by appropriately controlling the speed difference between the first conveyor 1 and the second conveyor 2, the articles A can be aligned on the second conveyor 2 at substantially equal intervals.

Further, in FIG. 4, when a predetermined number of articles A are sent from the second conveyor 2 to the alignment passage 25a, the first conveyor 1 is expanded or contracted by the interval T of each alignment passage by setting a timer or the like. By moving the second conveyor 2 to the adjacent alignment passage 25b, a fixed number of articles A can be sent to the alignment passage 25b. Then, by repeating the expansion and contraction of the first conveyor 1 at the intervals T at regular time intervals, it is possible to distribute the equal amount of articles A to the respective alignment passages 25a to 25e.

The articles may be sent to each of the alignment passages 25a to 25e in a random order as well as in order.
