Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magazine positioning device that positions magazines or pallets on a free flow conveyor at a constant pitch.

Conventional magazine positioning devices are complicated, using a rack and pinion mechanism, and have the disadvantage of requiring a large installation space. The present invention is intended to eliminate the drawbacks of the above-mentioned secondary structure, and embodiments thereof will be described below with reference to FIGS. 1 to 8.

In the figure, reference numeral 1 denotes a rotating shaft that is connected via an axis la to a timing pulley 3 rotated by a timing belt 2, and is located at a rotational angle position calculated by dividing 360 degrees on the circumference by the required number of magazine positions, and A large number of stopper pins 4 are coupled at positions corresponding to the magazine feed pitch distance in the direction.

Reference numeral 5 denotes a slit plate for detecting the origin connected to the end of the rattan la of the rotary shaft 1, and 6 is a slit plate for detecting one pitch, each of which is provided with photo sensors 7 and 8 for detection.

9 is a rotating timing pulley, and the pulley rotating gear 1 is coaxially connected to the rotating timing pulley.
・0 is connected, rotational motion is transmitted by intermediate gear 11,
Geneva 12 and Geneva wheel 13 perform intermittent motion, and power is transmitted from electric motor 14a and reduction gear 14b.

Reference numeral 15 designates a magazine comprised of magazine storage sections 16 arranged at regular pitches, 17 a free flow compare belt supported by a belt receiver 18, and 19 a magazine guide.

Note that a pair of rotating shafts 1 are installed around the center of the conveyor, and the slit plates 5 and 6 are connected only on one side. Further, 20 is a belt tension roller for eliminating slack in the timing belt. The magazine 15 moving forward on the free flow conveyor is positioned by the left and right stopper pins 4 which are set in advance at the origin position by the origin detection photo sensor 7, and then, after transferring the articles from the first magazine storage section 16, Upon receiving a movement completion confirmation signal from another device (not shown), the electric motor 14a rotates.
The interpolation motion is transmitted through the Geneva 12, the rotary gear 10, the timing belt 2, and the timing pulley 3, and the rotary shaft rotates by a predetermined angle.The photo sensor 8 for detecting one pitch detects the predetermined position and stops. Pin 4 sets the next magazine stop position. In this way, while the magazine 15 is moved one pitch at a time to each magazine storage position, the transfer of the articles in each storage section is completed. Therefore, by using this magazine constant pitch positioning device, it becomes possible to sequentially supply the articles stocked in the magazine. In the above embodiment, a device for positioning the magazine at a fixed pitch is used, but a pallet having another configuration may be used.

Next, other embodiments of the present invention will be described.

In this embodiment, the drive system of the rotary shaft 22 is changed, and in FIG. A rotary shaft 26 is connected to the rotary shaft through which a number of stopper pins 25 are driven in at positions corresponding to a rotation angle obtained by dividing 360 degrees by the magazine positioning number and at positions spaced apart by the magazine feed pitch distance in the koji direction. The shaft has a rotating gear 24 at one end, an origin detection slit plate 27 and a 1 pitch detection slit plate 28 at the other end.
are connected and can be rotated by a bearing 29. 7 is a photo sensor of the origin detection slit plate 27, and 8 is a photo sensor of the 1 pitch detection slit plate 28.

Structures other than those described above are the same as those in the first embodiment, so explanations will be omitted.

\15 is a magazine that crosses the magazine groove 16 at a constant pitch, 17 is a free flow compare belt supported by the belt receiver 18, and 19 is a magazine guide.

Incidentally, a pair of magazine fixed pitch positioning devices are installed within the conveyor, centered around the sewata. In this embodiment as well, the magazine 15 flowing on the free flow conveyor is
The origin position is determined in advance by the set left and right stopper pins 25 using the origin detection slitter plate 27.

Next, after transferring the item from the magazine, the synchronous motor 21 with reduction gear rotates in response to the confirmation signal, rotates the rotary shaft 22 by a certain angle confirmed by the 1-pitch detection photo sensor 8, and then Positioning is performed by a stopper pin 25. By repeating the above operations, the article storage grooves of the magazine are sequentially moved and the transfer is completed. According to the present invention, it is effective for supplying or storing a required amount of items from magazines or pallets when needed in large quantities, and has a simple structure and requires less installation space. It has the advantage of being easy to use and can be manufactured at low cost.
