【Example】

 Next, an embodiment embodying the present invention will be described to provide an understanding of the present invention. 1 is a schematic side view of an article conveying apparatus according to an embodiment of the present invention, FIG. 2 is an overall plan view of the article conveying apparatus, FIG. 3 is a partial sectional view of the article conveying apparatus, and FIG. It is a partial side view. As shown in FIGS. 1 to 4, an article conveying apparatus 10 according to an embodiment of the present invention includes a chain 13 driven by front and rear drive sprockets 11 and a guide 14 provided on both sides of the chain 13. , 15, rotary drive means 16, 17 for the drive sprockets 11, 12 and a mount 18 for fixing them. These will be described in detail below.

The chain 13 is composed of a normal link chain having a link plate and pins, and in this embodiment, attachments 19 are attached at every 4 link pitches. The attachment 19 is provided with protrusions 20 and 21 extending on both sides, and the protrusions 20 and 21 are slidably moved on the upper surfaces of the guides 14 and 15 provided on the loosening portion 22 of the chain 13. In addition, an auxiliary tool 23 is provided on the top of the attachment 19 to put a dried kamaboko, which is an example of an article.

The rotation driving means 16 for driving the sprocket 11 on the front side that meshes with the chain 13 has a Geneva rotating portion 25 connected to a rotary shaft 24 on which the splot 11 is mounted, and a Geneva rotating portion 25. A cam plate 27 attached to the input shaft 26, rotary solenoids 28 and 29 for controlling the driving of the cam plate 27, a torque transmission unit 30 for transmitting a constant rotational torque to the cam plate 27, and the torque transmission. A gear motor 31 that transmits a dynamic force to the portion 30 is provided.

As shown in FIG. 4, torque is transmitted to the cam plate 27 by the rotational force of the gear motor 31, and when either one of the rotary solenoids 28 and 29 is turned on, the stop pin 32 of the cam plate 27 is turned on. Comes off, and the cam plate 27 makes a half turn. When the cam plate 27 makes a half rotation, the drive pin 33 constituting the Geneva rotating portion 25 rotates 180 degrees, the Geneva plate 34 rotates 90 degrees, the sprocket 11 drives 90 degrees, and the attachment 19 is moved to a predetermined position. Move a distance. Here, since the rotational force of the gear motor 31 is transmitted to the sprocket 11 via the Geneva rotation unit 25, the rotation speed at the time of starting and stopping is slow, and the chain 13 is smoothly fed. It can be carried out. Thereafter, by driving the other rotary solenoid, the cam plate 27 is further rotated by 180 degrees, and the sprocket 11 is rotated by 90 degrees. As a result, the dried kamaboko on the auxiliary tool 23 can be discharged.

The rotation driving means 17 on the rear side that meshes with the chain 13 has the same structure as the rotation driving means 16, so a detailed description thereof will be omitted, but in the case of continuously supplying dried kamaboko First, the front sprocket 11 continuously performs the above operation, and the rear sprocket 12 intermittently operates at a speed higher than the rotation of the front sprocket 11. That is, when the chain 13 located in the loosening portion 22 is loosened and the attachments 19 are arranged adjacent to each other by a predetermined number or more, this is detected by the sensor and the drive of the sprocket 12 is stopped. When the number of the attachments 19 is less than the predetermined number, the sprocket 12 is rotated at a high speed and a large number of the attachments 19 are sent to the loosening portion 22. The dried fish paste as a product to be conveyed is put into the auxiliary tool 23 at the time when the chain 13 passes through the drive sprocket 12 or after the chain 13 passes, and when the dried fish paste is discharged from the auxiliary tool 23, the sprocket is removed. It is automatically performed when the chain 13 passes through 11.

Although the protrusions 20 and 21 are provided on both sides of the attachment 19 in the above-described embodiment, the pins of the unit chain to which the attachment 19 is attached are extended in both directions or the link plates of the unit chain are attached. It is also possible to extend in both directions so as to contact and slide on guides on both sides, and further, by providing rollers on the pin of the unit chain, it is possible to roll on the guides. Furthermore, it is also possible to lengthen the slackening portion and provide an attachment stop portion, whereby the articles (including the raw materials) can be discharged simultaneously from the individual attachments while the attachments are lined up at the same time. It can be performed. In this embodiment, the dried kamaboko was used as the article to be conveyed, but it is natural that the present invention can be applied to medicinal products, other powders or small items to be added to instant noodles.

[0012]

[Effect of the device]

 As is clear from the above description, the article transporting device according to claim 1 drives the chain conveyor because the attachments are attached to the chain at a pitch of 4 link pitches or more so that only the chain can be loosened. In this case, the attachment can be moved without driving the entire chain, which reduces the load and allows the article to be conveyed at high speed. Further, even when the chain conveyor is being driven, it is possible to stop the attachments in the loosened part, and the articles are simultaneously supplied to the attachments arranged in the stopped state or the auxiliary tools provided in the attachments. Therefore, when a relaxing portion of appropriate length is provided, it is possible to carry out parallel receipt and serial shipment of many articles in succession.
