DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is a container supply device which takes out containers which are conveyed in a dense state on a supply conveyor one by one by a take-out means such as a screw and supplies them in a line to the next step. , A rotating belt for forcibly feeding the container is provided on one side of the supply conveyor, and a swingable guide member is provided opposite to the rotating belt. This is a container supply device that can be supplied to a container. An embodiment of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a schematic plan view showing a main part of the container supply device of the present invention, and FIG. 2 is a schematic front view showing the same main part. In the drawing, reference numeral 2 denotes a supply conveyor for transporting the loaded ampule 1 to the downstream side, and reference numeral 3 denotes a rotary belt device provided with a rotary belt 4 forming one side of the supply conveyor 2, and a frame of the supply conveyor 2. 6 "lower base attached to
To the upper base 6 ′ which is screwed through the long hole 13,
Pulleys a, b, c, and d are provided rotatably.
The upper base 6 'and the lower base 6 "
The upper base 6 'and the lower base 6 "are fixed by screwing a bolt 15 into the upper end of the upper base 6'. A motor 5 is provided, and a pulley e is fixed to a motor shaft 12 of the motor 5. The rotating belt 4 includes pulleys a,
The motor 5 drives the motor 5 to convey it on the supply conveyor 2 and rotates the ampoule 1 in contact with the rotating belt 4 in a direction that applies a propulsive force to the downstream side. The rotating belt device 3 can swing with the pulley a as a fulcrum along with the upper base 6 ', and can be adjusted when the diameter of the ampoule 1 to be handled is changed. By doing so, the rotary belt 4 can be swung about the pulley a on the upstream side as a fulcrum, and the angle can be adjusted, so that the target container can be spread over a wide range. Reference numeral 7 denotes a guide member provided to face the rotating belt device 3. One end of the guide member is screwed to a fixed conveyor guide 8 at a connecting portion 7 a, and the other end is provided at the tip of a cylinder 9. It is in contact with the inclined portion 10a of the triangular guide 10, and is arranged in a bow shape as shown in FIG. A Teflon sheet is attached to the surface of the guide member 7 to prevent the ampule 1 from being damaged. When the triangular guide 10 moves forward and backward by the cylinder 9, the guide member 7 swings about the connecting portion 7 a as a fulcrum, and applies a pressing force to the ampule 1 on the supply conveyor 2. Numeral 11 denotes a screw for accommodating the ampoule 1 conveyed on the supply conveyor 2 one by one in the groove 11a and transferring the ampoule 1 to a star wheel. The ampule 1 is guided by a head guide, a body guide and a bottom guide. Let me twist
It is handed over to the star wheel of the washer when it is turned over. Next, the operation of the present invention will be described. The ampoule 1 placed on the supply conveyor 2 by means not shown is conveyed in a dense state toward the screw 11, and the ampoule 1 reaching the screw 11 is sequentially placed in the groove 1
1a and transported downstream (to the right in FIG. 1). At this time, the groove 11a of the screw 11 is
Since the starting portion (the left end in FIG. 1) is always empty, the ampule 1 is concentrated and stored in the starting portion of the screw 11. As a result, the ampules near A in FIG. 1 are concentrated and accommodated in the screw 11.
Since the propulsive force is applied, it is conveyed to the screw 11 while always maintaining a dense state. The guide member 7 is periodically swung about the connecting portion 7 a as a fulcrum by the reciprocating movement of the triangular guide 10 provided at the tip of the cylinder 9, and is transferred to the ampoule 1 which is conveyed on the supply conveyor 2. Pressing is performed periodically upward and diagonally to the left in FIG.
Is caused by the conveying force of the supply conveyor 2 and the rotating force of the rotating belt 4 and the screw 11, as indicated by a counterclockwise arrow shown in FIG. By promoting the flow by the pressing force of the guide member 7, the ampules 1 on the supply conveyor 2 can be kept in a dense state at all times.
Even if the container is unstable, it can be stably transported. Further, the straight portion 10b of the triangular guide 10 is
The function of preventing the bridge phenomenon of the ampoule 1 and the function of pushing the ampoule 1 into the groove 11a in which the ampoule 1 is not accommodated and is in a toothless state. The ampoule 1 housed in the groove 11a of the screw 11 is conveyed downstream while contacting the groove 11a of the screw 11, and the head guide,
Twist while supporting with the body guide and bottom guide,
Hand over to the star wheel of the washer in a rollover state. At this time, the shape of the groove 11a of the screw 11 is such that the ampoule 1 can be conveyed perpendicularly to the central axis of the screw 11 at the beginning. That is, the width of the groove 11a is set to be larger than the diameter of the ampoule 1, and when the ampoule 1 is accommodated along the inclination of the groove 11a, a gap is generated to some extent. On the other hand, the twist portion (not shown) has a width that the ampule 1 conveys along the inclination of the groove 11a. In other words, the width of the groove 11a is narrower than the starting portion, and the width of the ampoule 1 cannot be accommodated unless the ampoule 1 follows the inclination of the groove 11a. Therefore, the ampoule 1 is forcibly conveyed along the inclination of the groove 11a. Is done. Therefore, at the time of twisting, the ampoule 1 is firmly held in the groove 11a of the screw 11, so that the ampoule 1 is displaced sideways in the middle of the twist.
And do not overlap. Thus, the ampoule 1 turned over is
Although it is conveyed in an oblique state along the inclination of the groove 11a of the screw 11, at the discharge position of the screw 11,
The groove 11a of the screw 11 has a width such that the ampoule 1 can be conveyed vertically with respect to the center axis of the screw 11 as in the start portion, so that the ampoule 1 can be in a vertical state. Also, even when the ampoule 1 is supplied to the star wheel 15 in an oblique state, the head of the ampoule 1 is first lifted by the head star wheel, and the trunk of the ampoule 1 is delayed. It is housed in the star wheel for the body, but the pocket of the star wheel for the body is eccentric on the rear side and is large, so even if the body of the ampoule 1 is delayed, it is stably stored in the pocket. It can be accommodated. Thus, the ampoule 1 housed in the star wheel is washed in a washing section (not shown) and sent to the next step. As described above, the rotary belt device 3 for forcibly transferring the drive pulleys is driven by the denseness of the containers on the conveyor and the manner in which the containers are reduced (in the illustrated case, the containers are sequentially fed counterclockwise). The angle can be changed around the center. Further, as another example, the rotating belt device 3 may feed an unstable container by using projecting teeth on both sides of a commercially available toothed belt. In this case, the container can be forcibly fed more reliably by using the rotating belt as a toothed belt. In addition, the supply conveyor 2 is conventionally generally transported with a slight downward inclination, but the present invention is substantially horizontal to prevent the supply conveyor 2 from falling down. According to the present invention, as a result of employing the above configuration,
The following effects can be obtained. (1) When supplying a row of unstable containers, such as ampules, that are difficult to stand by, a rotating belt and a swingable guide member are provided so that the container can be bridged by the linear portion of the guide.
Prevents elephants and makes the toothless state without containing the container
It worked to push the container into the groove of the new screw, preventing the occurrence of pockets and enabling stable supply.
