The present invention relates to a rod-shaped article supplying device that can also feed out rod-shaped articles in sequence.

[Conventional technology]

To measure the quality of cigarette filter plugs,
One by one is randomly taken out from among the many stored filter plugs and supplied to the quality measuring device.
It is necessary to measure in a random order, or to measure in units of, for example, 1 package (usually 20 packages) and calculate the average value and standard deviation for each unit. The structure of a feeding device that feeds in unit order and a feeding device that feeds in unit order are completely different.

As for the structure of the former feeding device, a hopper type feeding device as shown in FIG. 6 is used.

This hopper type feeding device includes a receiving cylinder 1 having a plurality of groove-shaped receiving portions 1a on its outer circumferential surface;
It is composed of a supply means including a guide 2 covering a part of the outer peripheral surface of the receiving cylinder 1, and a hopper 3 having a supply port 3a close to the outer peripheral surface of the receiving cylinder 1.

The samples 4 such as filter plugs stored all at once in the hopper 3 are accommodated one by one in the housing section 1a by the rotating receiving cylinder 1, and are fed downward as the receiving cylinder 1 rotates. However, the supply order is completely random.

In order to supply the sample 4 in packets, a special supply device is used as shown in the partially cutaway front view of FIG. 7 and the longitudinal sectional view of FIG. 8.

In this supply device, a supply box 7 is movably provided on positioning guides 6 on both sides of a supply stage.

A ball spline shaft 8 and a rack 9 are installed on the side of the supply stage 5 in the same direction as the positioning guide 6, and the ball spline shaft 8 has two arms, a supply box fixing arm 10 and a supply box moving arm 11. engaged.

The supply box fixing arm 10 mainly regulates the position of the supply box 7, and is in contact with the right end of the supply box 7. It has a function of moving the supply box 7 to the left in FIG. 7 when the box 7 returns, and the supply box moving arm 11 is directly connected to the motor 12 and engages with the left end of the supply box 7 to move the supply box 7 to the right. Perform movement in the direction.

Reference numeral 14 denotes a cylinder for a supply box fixing arm, and when the supply box 7 reaches a predetermined position, the supply box fixing arm 10 is pressed against the supply box 7 to hold the supply box 7 at that position.

Shutter guides 15 are attached to both lower sides of the supply box 7. A plate-shaped shutter 16 that contacts the bottom of the supply box 7 is movably supported on the shutter guide 15. The sample 4 in the tray 17 is stored at the bottom of the tray 17 and has an opening at the bottom to prevent the sample 4 in the tray 17 from falling off. It is designed to fall downward through the supply port 16a.

The plurality of trays 17 in the supply box 7 are arranged so as not to be displaced by spacers 18 inserted into the supply box 7.

Below the supply stage 5, a supply means similar to that shown in FIG. It falls from the end and is supplied to the next process.

The sample 4 is first supplied to the tray 1 in the storage box 7.
The rightmost tray 17a among the trays 17a reaches above the supply port 16a, and the samples in the tray 17a are stored one by one in the storage section 1a, and are intermittently supplied downward as the receiving cylinder 1 rotates.

After the samples 4 in one tray 17a have been supplied, the samples 4 in the next tray 17a are dropped and supplied from the supply port 16a, and supply is performed in units of trays.

[The problem that the idea attempts to solve]

As explained above, when a large number of samples 4 are taken out at random and supplied to a measuring device, a hopper-type random sequential delivery device as shown in Fig. 6 is used. If samples are to be measured in batches, the packet feeding apparatus of FIGS. 7 and 8 must be used.

However, due to the aggregation of measurement data, there are cases where measurements are taken in a fixed order and cases where measurements are made in a random order.
There is a problem in that it is necessary to prepare different kinds of supply devices and perform troublesome setup work to replace and install them with an automatic quality measuring device, or to install two quality measuring devices each equipped with a respective supply device.

The present invention aims to solve this problem, and provides a feeding device that can select and use two types of feeding order with one feeding device. It can be used for supplying cigarettes and other stick-shaped articles without limitation.
