いる。2. Description of the Related Art Containers conveyed continuously on a line,
Various cap screwing devices have been proposed for screwing a screw-type cap into a threaded mouth. For example, first, the screw-type cap is put on the mouth portion of the container in which the screw thread is formed, or the screw-type cap is put on the mouth portion of the container, and then temporarily tightened and lightly tightened. There is a cap screwing device that performs a final tightening by tightening a screw-type cap with a predetermined torque using the cap screwing device. As a cap temporary tightening device for performing the above-mentioned temporary tightening, an elongated plate shape for temporary tightening that extends along the container carrying direction on the side of the cap that covers the mouth of the container carried on the line. The container is conveyed on the line with the side surface of the threaded cap placed on the mouth part of the container in contact with the elongated member, and the contact between the cap and the elongated member causes the screw to move. A cap temporary tightening device that temporarily tightens the cap by rotating the cap of the formula has been proposed. When temporarily tightening the cap with teeth extending in the vertical direction (cap height direction) over the entire side surface of the cap, the entire surface of the elongate member for temporary tightening that contacts the side surface of the cap , Forming a tooth that can be meshed with the tooth formed on the side surface of the cap, and transporting the container covered with the cap along the line with the tooth on the side surface of the cap meshing with the tooth of the elongated member , The cap is rotated so that the cap is temporarily tightened.

要最小限の長さよりも長く設定されている。In this type of device, a screw thread is formed on the inner circumference of the cap when the temporary tightening is started by the contact between the cap covered on the mouth portion of the container and the elongated member,
The relative positional relationship with the threads formed on the mouth of the container is not constant. Therefore, as soon as the rotation of the cap is started, the start end of the screw thread of the cap and the start end of the screw thread of the mouth portion of the container are engaged and the temporary tightening is started.
Without limitation, after the cap covers the mouth portion of the container and rotates, for example, 180 °, the start end of the screw thread of the cap engages with the start end of the screw thread of the mouth portion of the container to temporarily tighten the cap. It may be started. Therefore, the length of the elongated member along the container transport direction is set to be longer than the minimum length required for temporarily tightening the cap.

を提供することを目的とする。The magnitude of the rotational torque applied to the cap by the engagement of the teeth on the side surface of the cap and the teeth of the elongated member is only the magnitude for temporarily tightening the cap. Therefore, when the temporary tightening of the cap is completed by the contact of the elongated member with the upstream side portion in the container transport direction, that is, the cap is temporarily tightened by meshing with the teeth of the upstream side portion in the container transport direction. If the container is transported to the downstream side in the transport direction with the teeth on the side surface of the cap meshing with the teeth on the downstream side portion in the container transport direction of the elongated member, the cap is still It cannot rotate any further, and the teeth on the side surface of the cap and / or the teeth on the downstream side of the elongated member in the container transport direction are scraped by the teeth on the other side. As a result, the cap and / or the elongated member may be damaged, and further, shavings generated by scraping one or both teeth may enter the container as foreign matter, which is a problem. The present invention has been made to solve the above problems, and an object of the present invention is to provide a temporary cap fastening device that has a simple configuration and that can suppress the generation of foreign matter as much as possible.

しにくくなる。Further, when the temporary fastening of the cap is not completed due to the contact with the upstream side portion of the temporary fastening member in the container conveying direction, the frictional contact between the teeth of the cap and the surface of the downstream side portion of the temporary fastening member in the container conveying direction causes The cap is driven to rotate and the temporary tightening is continued. Further, the above object of the present invention is to temporarily tighten a screw-type cap, which is covered on a mouth portion of a container conveyed on a line and formed with teeth extending in the longitudinal direction over the entire circumference of a side surface, to the mouth portion. A cap temporary tightening device that includes a temporary tightening member that extends along the transport direction of the container and that is arranged so as to come into contact with the teeth of the cap that covers the mouth portion.
The portion of the cap that contacts the teeth of the cap is provided with teeth that can mesh with the teeth of the cap, and the depth of the teeth formed in the portion of the temporary fastening member on the downstream side in the container transport direction is the container transport of the temporary fastening member. It is also achieved by a temporary cap tightening device having a depth smaller than the depth of the teeth formed on the upstream side in the direction. According to the cap temporary tightening device having such a configuration, the play between the teeth of the temporary tightening portion and the teeth of the cap becomes large in the downstream side portion of the temporary tightening member in the container transport direction. Therefore, even if the temporary fastening of the cap is completed by the contact with the upstream side portion of the temporary fastening member in the container transport direction, the number of times the teeth of the cap and the teeth of the downstream side member of the temporary fastening member in the transport direction of the container are small. Therefore, scraping is less likely to occur between the teeth of the cap and the teeth of the member on the downstream side of the temporary fastening member in the container transport direction.
