As described above, according to the present invention, the link arm for adjusting the transport interval of the containers transported on the transport conveyor is brought into contact with the rotating support shaft capable of adjusting the vertical position and the body of the container. A parallelogram link structure with contact pieces that can contact,
And the tip of a part of the link arm is received by the link arm support base, the base of the link arm is moved up and down by moving the rotation support shaft up and down to change the radius of rotation, thereby changing the outer diameter. Since it corresponds to the container,
It can be handled simply by changing the vertical position of the rotating spindle, and the structure is extremely simple.In addition, the position of the contact piece at the tip of the link arm is constant even if the distance between the tip of the link arm is changed It is not necessary to adjust the height each time it is in the position, so that the number of drive motors to be installed can be reduced, and the control of the device becomes very easy. Further, since the contact piece is placed in a vertical position regardless of the rotation radius of the link arm, the contact piece can be stably brought into contact with the container, and the transport interval of the container can be reliably adjusted. .

1. A container spacing adjusting device for adjusting a container on a transfer conveyor to a predetermined transfer interval and transferring the container to the next step, wherein the container is located on one side of the transfer conveyor and is separated from and brought into contact with the conveyor by a driving means. A base that can move in the direction, a rotation support shaft that is erected on the base and rotated by a rotation drive unit, and an upper arm rod that is substantially equal in length on a bearing ring provided above the rotation support shaft. The base ends of the lower arm rods are pivotally supported at vertical intervals, and a contact piece is pivotally supported between the upper and lower ends of the lower arm rods to form a parallelogram link structure and are arranged at equal intervals in the radial direction A plurality of link arms, a shaft cylinder fitted slidably in the axial direction relative to the rotation support shaft, a support rod for connecting a bearing portion of the shaft cylinder and the link arm, and It is provided on the table at a position opposite to the conveyor, and the lower surface on the tip side of the link arm is in sliding contact A link arm support base having a substantially fan shape in a plan view, and an elevating drive unit for elevating the rotary support shaft, and selecting the vertical swing position of the link arm by raising and lowering the rotary support shaft. An apparatus for adjusting a container interval in a transport conveyor, wherein the interval between contact pieces at the tip of a link arm is changed to match the interval at which containers are to be transported.
