Abstract

PURPOSE:To simplify a delivery unit between an intermittent mobile machine and a continuous mobile machine in structure and miniaturize it in addition by overlapping a part of each moving area of both these machines, installing a delivery area of constant length, and making each delivery part of these machines so as to parallelly traveled at the same speed in the area. CONSTITUTION:A feeding head 14 of an intermittent mobile machine 11 repeats its travel and stop in an intermittent moving area, while a receiving head 18 of a continuous mobile machine 12 continuously moves, and each moving locus of both these heads 14, 18 is overlapped in an overlap moving area. Within an equal speed range K in a delivery range L set up in an overlap moving range, these heads 14, 18 are constituted so as to be parallely traveled at the same speed. Consequently, whining this delivery range K, there is no relative movement between these heads 14, 18 so that they parallely travel, thus allowance is giveable to the delivery time and thereby positive delivery can be done. With this constitution, a structure can be simplified and miniaturized.

The continuous movement range 4 is set to follow the transfer range determined on the rotation locus of the rotating machine 5, and the transfer section of the free flow conveyor 2 and the receiving section of the continuous rotary machine 5 are set at the same speed in the transfer range. It is meant to run in parallel. According to this, the range of goods delivery between the intermittent mobile machine and the continuous mobile machine can be expanded to a linear range, and the necessary and sufficient time margin for the delivery of goods can be secured.

In addition, in the delivery device 1 shown in FIG. 7, by using the intermittent rotating machine 3, the articles supplied from the external article supply source are reliably delivered to the delivery section in the stopped state of the intermittent rotating machine 3. and can be easily transferred.

etc., the transfer section of the free flow conveyor 2 is moved intermittently by the intermittent rotating machine 3, and the transfer section is moved in such a way that it runs parallel to the receiving section of the continuous rotating machine 5 at the same speed. It is necessary to start continuous movement using the timing screw 4A and the star wheel 4B, and as a result, the device configuration must become complicated and large.

An object of the present invention is to provide a delivery device for delivering articles between an intermittent moving machine and a continuous moving machine using a simple and compact device configuration.

The transfer section or the receiving section on the side of the intermittent mobile device is configured to transfer at least one part of the transfer range within the transfer range provided over a certain length range in the overlapping movement area of the intermittent mobile device and the continuous transfer device. Within the same speed range specified in the section, the continuous moving machine will run parallel to the corresponding receiving section or sending section at the same speed. That is, in the same speed range within the above-mentioned delivery range, the transfer section or receiving section on the intermittent moving machine side and the receiving section or sending section on the continuous moving machine side run parallel without relative movement, so this parallel running period Articles can be delivered between the delivery section and the receiving section within a necessary and sufficient time margin.

In the present invention, as described above, a delivery range is provided within the movement area of the intermittent mobile machine, which shares a certain length range with the continuous mobile machine, and a delivery part and a receiving part are provided within the delivery range. By establishing a same speed range in which the two machines run in parallel at the same speed, there is no need to attach a transfer adjustment device such as a free conveyor in addition to the intermittent moving machine and the continuous moving machine, and the simple and compact device configuration allows the intermittent moving machine and the continuous moving machine to Items can be delivered to and from continuous moving machines.

In this embodiment, each paper feeder 15 is provided at the first station (No. 1) of the intermittent rotating machine 11,
Each paper feeder 15 feeds a respective paper 16 of a container to the transfer head 14 which is in stoppage B at this station.

The continuous rotary machine 12 has a rotary table 17 that can be continuously rotated through a 360 degree movement range by a known chain drive method, for example, and has receiving heads 18 consisting of vacuum heads at a plurality of positions in the circumferential direction of the table 17. We are prepared. At this time, the spacing between adjacent receiving heads 18 of the continuous rotating machine 12 is the same as the spacing between adjacent delivery heads 14 of the intermittent rotating machine 11.

In this embodiment, the continuous rotary machine 12 is equipped with container holders 19 at the same positions around the rotary table 17 corresponding to each receiving head 18, and a container feeder 20 is provided at the first station (No. 1). A container 21 filled with contents is put into each container holder 19 passing through this station. Continuous rotating machine 12
Under the continuous movement state, the corresponding receiving head 18 and one container holding part continuously rotate vertically relative to each other!
