Description

  The present invention relates to a self-contained container delivery / conveying device that sequentially and sequentially delivers containers to a horizontal rotary processing device in a liquid filling line, and in particular, can grip the neck of the container and reliably center it. The present invention relates to a gripper-type delivery / conveying device capable of processing such as cleaning and filling in a container.

  When transferring a container from one horizontal rotary processing device to another horizontal rotary processing device, for example, from the horizontal rotary star wheel to the rotary liquid filling machine, through the second star wheel from the rotary liquid filling machine, to the next When the container is delivered to the rotary function equipment of the former, it was previously supported by a star wheel with a recess that fits the cross-sectional shape of the container body at the same pitch as the container transport pitch and a disk that supports the bottom of the container. I was delivering and transporting while rotating. In this container delivery system, when changing the shape and size of the container, the two star wheels were replaced, and the height of the disc supporting the bottom of the container was changed. In recent years, various gripper (clamp) type conveying apparatuses that can cope with changes in the shape and size of the container without replacing the star wheel have been proposed.

For example, as shown in the clamp-type transport device described in Patent Document 1 (Japanese Patent No. 2697536), the transport device is a rotating body, and a plurality of clamps composed of a pair of left and right clamp arms are arranged on the circumference. In a configuration arranged at an equal pitch, a positioning member capable of adjusting the radial position of the rotating body is provided between the clamp arms of each clamp, and the container is gripped by the clamp and the positioning member and conveyed on the rotating body. The The clamp is operated by a cam attached to the fixed member so that the left and right clamp arms rotate in reverse directions to open and close, and clamps the container at a predetermined position.
The positioning member is configured such that a cam roller attached to the member engages with a plurality of helical groove cams rotatably attached to the rotating body, and the helical groove cams are relative to the rotating body according to the outer diameter of the container. It is possible to adjust the protrusion amount of the positioning member by turning it.

In the conventional example of the gripper-type transport device described in Patent Document 2 (Japanese Patent Laid-Open No. 8-310653), the containers fed with the same feed pitch and direction are arranged at equal pitches on the circumference of the rotating body. The gripper is gripped by the plurality of grippers arranged and conveyed on the rotating body. The gripper has a pair of left and right gripper arms and is opened and closed at a predetermined angular position of the rotating body by the gripper opening and closing means.
The gripper opening / closing means rotates the control lever installed on the rotating body by contacting a contact pin provided on the fixed member and rotates the expansion body (elliptical cam) directly connected to the control lever, thereby opening and closing the gripper arm. To do. The expansion body operates so that the gripper arm grips the container. Adjustment of the opening width of the gripper is set by moving the contact pin and changing the rotation angle of the control lever.

  The above gripper type transport device is suitable for a resin container transport device that is lightweight and easily selectable in cross-sectional shape, and the transport function of this transport device is used in combination with a filling machine and a cleaning device in the container, For example, attempts have been made to simplify the production line in which a conveyor with a container indexing unit is directly transferred to a filling machine with a transfer device, and after the container is filled with liquid, it is directly transferred to a transfer device such as the next conveyor.

However, the neck of many resin containers is provided with a fairly large diameter ridge for facilitating container delivery between star wheels, and if the line handles only containers with a constant neck size, For example, when delivering to a rotary liquid filling machine, when a star wheel provided with a recess matching the cross-sectional shape of the neck is attached to the filling machine at the same pitch as the conveyance pitch of the container, and the container is supported by this star wheel, In general, a container that is filled with a liquid by holding the outer peripheral side and centering the container is used.
