DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

(6) Referring to FIGS. 1 and 2, a bottle conveyor includes a platform 1 and a bottle-stopping apparatus according to the preferred embodiment of the present invention. The bottle-stopping apparatus includes a driving unit 2, a following unit 3, a transmission 4 and two stoppers 5.

(7) In operation, the platform 1 supports bottles such as large bottles 6 shown in FIG. 3 and small bottles 6A shown in FIG. 4. The platform 1 includes a lateral plate that includes two slots 11 and 12. The slots 11 are 12 are identical to each other in length. The slot 11 is located higher than the slot 12.

(8) The driving unit 2 includes two bearings 21, a driving axle 22, a driving pulley 23 and a knob 24. One of the bearings 21 is located under the platform 1, and the other bearing 21 is located near the lateral wall of the platform 1. The driving axle 22 is supported on the bearings 21. The driving axle 22 extends through an aperture made in the lateral wall of the platform 1. The driving pulley 23 is supported on the driving axle 22. The driving pulley 23 is located beneath the platform 1. The knob 24 is connected to an end of the driving axle 22. The knob 24 is operable to rotate the driving axle 22. The knob 24 can be replaced with a lever or the like in another embodiment.

(9) The following unit 3 includes a bearing 31, a following axle 32, a following pulley 33 and a knob 24. The bearing 31 is located under the platform 1. The following axle 32 is supported on the bearing 31. The following axle 32 extends through an aperture made in the lateral wall of the platform 1.

(10) The transmission 4 includes a belt 41 and two connectors 42 and 43. The belt 41 is in the form of a loop extending around the driving pulley 23 and the following pulley 33 so that the driving axle 22 rotates the following axle 32 via the pulleys 23 and 33 and the belt 41.

(11) The connector 42 includes two plates 421 and 422 connected to each other by several screws 423 for example. An upper section of the belt 41 is sandwiched between the plates 421 and 422 so that the connector 42 is connected to the belt 41.

(12) The connector 43 includes two plates 431 and 432 connected to each other by several screws 433 for example. A lower section of the belt 41 is sandwiched between the plates 431 and 432 so that the connector 43 is connected to the belt 41.

(13) In assembly, the belt 41 is located under the platform 1. The connector 42 extends through the slot 11. The connector 43 extends through the slot 12.

(14) Each of the stoppers 5 includes a movable element 51, a clamp 52, a post 53, a fastener 54, a rod 55 and a fastener 56. The movable element 51 is connected a corresponding one of the connectors 42 and 43 so that they are movable together with each other.

(15) The clamp 52 is connected to the movable element 51. The clamp 52 holds the post 53. The fastener 54 is rotatable in a direction to tighten the clamp 52 to keep the post 53 in position. The fastener 54 is rotatable in an opposite direction to loosen the clamp 52 to allow the post 53 to move. The fastener 54 preferably includes a lever. However, the fastener 54 can include a knob in another embodiment.

(16) The rod 55 is movably connected to the post 53 at an angle of about 90 degrees. The fastener 56 is rotatable in a direction to retain the rod 55 in position. The fastener 56 is rotatable in an opposite direction to allow the rod 55 to move. The fastener 56 preferably includes a knob. However, the fastener 56 can include a lever in another embodiment.

(17) As discussed above, the clamp 52 and the fastener 54 are operable to adjust height of an operative end of the rod 55 via the post 53 according to the size of bottles to be stopped by the bottle-stopping apparatus. Moreover, distance of the operative end of the rod 55 from the post 53 is adjustable corresponding to the size of the bottles to be stopped by the bottle-stopping apparatus.

(18) Referring to FIG. 3, the large bottles 6 are conveyed by the bottle conveyor. The knob 24 is operable to move the posts 53 away from each other, thereby increasing the gap between the posts 53 in compliance with the width of the large bottles 6. The stoppers 5 are moved away from each other as indicted by two arrowheads as the knob 24 is rotated counterclockwise as indicated by another arrowhead.

(19) Referring to FIG. 4, the small bottles 6a are conveyed by the bottle conveyor. The knob 24 is operable to move the posts 53 toward each other, thereby reducing the gap between the posts 53 in compliance with the width of the small bottles 6a. The stoppers 5 are moved toward each other as indicted by two arrowheads as the knob 24 is rotated clockwise as indicated by another arrowhead.

(20) Advantageously, the knob 24 is operable to synchronously move the stoppers 5 due to the use of the belt 41 to connect the driving pulley 23 to the following pulley 33. Hence, the adjustment of the locations of the stoppers 5 is efficient. Moreover, the stoppers 5 are always moved for a same distance for using the belt 41 to connect the driving pulley 23 to the following pulley 33. That is, a middle point between the operative ends of the rods 55 is not moved. Therefore, the adjustment of the locations of the stoppers 5 is precise.

(21) The present invention has been described via the illustration of the preferred embodiment. Those skilled in the art can derive variations from the preferred embodiment without departing from the scope of the present invention. Therefore, the preferred embodiment shall not limit the scope of the present invention defined in the claims.
