Abstract

PURPOSE:To control height of the whole of a device without any facilities for a rise for throwing to an automatic weighing device and a packaging device by providing a weighing position on a lower part where a hopper is vertically rotated and a products discharge position on an upper part. CONSTITUTION:Products carried by a supply conveyor 5 are divided 10 into arbitrary weight, dropped in a waiting hopper 4, thrown to a hopper with a weighing device in harmony with movement timing of a dispersing hopper 1 and a weighed value is stored to a computer. The stored and weighed products are thrown to the dispersing hopper 1, combination operation between groups of the hoppers 1 is performed as the rise is performed as the groups of the hoppers 1 and specified weight is obtained. The groups of the hoppers 1 wherein the specified weight is obtained are successively collected at a position of a second hopper 6. Because the groups of the hoppers 1 are combined in front and rear, the two hoppers 6, the total of which indicates the four hoppers, are provided under a movement line of the hopper 1, the products of the specified weight collected at the position of the hopper 6 are horizontally rotated in the side of the packaging device 11, thrown down from a receiving opening 12 and the released hopper 6 is returned back to the position of the hopper 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the simplicity of automatic weighing machines.

[0002]

2. Description of the Related Art Conventionally, in an automatic weighing machine, articles are once conveyed to a high place (2.5M or more) for weighing, and after the weighed articles are combined and selected, the articles are dropped to a predetermined weight. Is getting

[0003]

By the way, in such an automatic weighing machine, the position at which the predetermined weight is reached becomes lower on the contrary, so that a device for raising it again for loading it into the packaging machine or the like is required. In addition, the equipment of the same price as the main body of the weighing machine is required, the whole apparatus becomes very expensive, and there is a space problem. The object of the present invention is to eliminate the equipment for ascent for automatic weighing and loading into the packaging machine,
Another object is to suppress the height of the entire device.

[0004]

According to the present invention, the above object is to connect a plurality of hoppers each having at least one sided lid that can be opened and closed in a chain form and to endlessly rotate the group of hoppers. Articles are accommodated in the hopper at a predetermined position on the moving lower side of the rotation, the upper portion of the hopper is covered with a lid, and the lid is opened and stored at a predetermined position at the upper portion of the vertical rotation where the hopper is inverted. Means for discharging articles, and a plurality of second hoppers for collecting and collecting articles discharged from the plurality of hoppers in a hopper different from the hopper.
And a means for moving to the second hopper after a predetermined number of articles have been discharged from the hopper, the second hopper
Is moved to a discharge position on a horizontal plane and discharges the contents. According to the present invention, first, the position to be weighed is provided in the lower part where the hopper rotates vertically, and the weighed articles are dropped into the hopper as they are,
A combination of predetermined weights is calculated while the hopper is raised, and a position for discharging the articles from the hopper is provided on the upper portion where the hopper vertically rotates, and the articles of the hopper having the predetermined weight are collected in the second hopper. After that, the product is horizontally rotated in the direction away from the main body side, the second hopper is released just above the receiving port of the packaging machine, and the article is discharged.

In FIG. 1 and FIG. 3, the material supplied to the supply bucket 9 is conveyed by the supply conveyor 5, and the separating apparatus 10 waits for an arbitrary amount (meaning that it is not constant) standby hopper.
4, and then put into the weighing hopper-3 in accordance with the movement timing of the distribution hopper-1. The objects put into the weighing hopper-3 are weighed, and the measured value is stored in a computer (not shown). The stored weighed items are put into the distribution hopper-1, and the weighed value of the items received by the distribution hopper-1 is determined. The objects thus sequentially loaded are lifted by the vertically rotating distribution hopper-1 group, and the combination calculation between the distribution hopper-1 groups is performed so that the predetermined weight is obtained (the calculation method is the conventional combination selection method). Adopt), and specify the distribution hopper-1 group for which the combination calculation is completed.

2 and 3, the specified group of distribution hoppers-1 are sequentially assembled in the second hopper-6 to obtain a predetermined weight. The second hopper-6 is provided so that the specified group of distribution hoppers-1 are combined one after the other so that there are always two below the movement line of the distribution hopper-1. Therefore, a total of four second hoppers 6 are provided. In the case of this embodiment, the number is four, but more than this is also possible. Items of a predetermined weight collected in the second hopper-6 are horizontally rotated to the side of the packaging machine 11 as they are, and when they are directly above the receiving opening 12 of the packaging machine 11, the second hopper-6 is released to discharge the articles. It is then put into a packaging machine. The released second hopper-6 returns to the position of the distribution hopper-1, and receives the new distribution hopper-1.

The embodiment of FIGS. 4 and 5 has a distribution hopper-1.
The slide shaft 14 is fixed to the conveyor chain 7, the shaft receiver 13 is provided on the transport chain 7, and the distribution hopper-1 is slidably attached. When the distribution hopper-1 is located at the upper part of the vertical rotation, the guide 8 sequentially moves it to the packaging machine side. In this case, the second hopper-6 is fixedly provided at the position where the distribution hopper-1 has moved to the packaging machine side. Also in the case of this embodiment, two second hoppers 6 are provided, and the second hopper 6 whose combination has been selected is selected.
Release from 6 and eject the object.

[0009]

According to the present invention, since the objects to be weighed are supplied from the lower part of the vertically rotating distribution hopper group, the feeding device is very low, and the objects selected in combination are elevated by the vertical rotation, so that the discharge position is high. In addition, since the discharge position is separated from the main body of the apparatus, there is a great advantage not seen in the prior art that connection with other connecting equipment such as a packaging machine can be made directly. As a result, the entire equipment can be made very small. Further, sticky things such as Tsukudani and pickles can be free from sticking in the middle of the equipment and troubles such as insufficient quantity because there are few connection equipments.
