A turntable has a plurality of intra-table tracks, each of which includes inlet and outlet end portion that is capable of communicating with a carrying-in and carrying-out side of the transporting track, respectively, wherein an object is transported from the inlet end portion to the outlet end portion, a table member on which the intra-table tracks are provided, a table rotating mechanism that rotates the table member to be stopped at an arbitrary rotation angle and a table rotation controlling mechanism. The table rotation controlling mechanism controls the rotation of the table member so as to set the transport direction of the transporting object transported through the intra-table tracks. The intra-table tracks are disposed in the table member so that when a transport direction of one of the intra-table tracks is set, the inlet end portion of any other intra-table tracks communicates with the carrying-in side of the transporting track.

The container of this invention is a squeezable laminated container of the delaminatable type in which the layers can be easily broken away from each other. The container comprises the first check valve fitted to the neck and has an opening in the bottom plate. The base cup comprises the second check valve, and is fitted tightly around the container bottom cylinder. In this discharge container, it is sought to secure stable and strong fitting and to maintain tight contact stably, between the container and the base cup. The container 1 is a squeezable and delaminatable bottle and is provided with a seal on the bottom cylinder 8. The neck 6 of the container 1 is opened or closed by the first check valve 18, and an opening 15 is formed in the outer layer 2 of the bottom cylinder 8 so that the opening 15 can be used as a port to introduce outside air into the interspace between the outer layer 2 and the inner layer 3. The base cup 20 is provided with the second check valve 27, which opens or closes the air intake hole 25 that has been opened in the cup bottom plate. This base cup 20 is tightly screwed on the container bottom cylinder 8, and a combination of seals closes the interstice between the container 1 and the base cup 20. The seals are disposed near the lower overhang 11, which serves as reinforcement for the peripheral bottom wall 9 of the bottom cylinder 8. Thus, it is possible to enhance the shape-holding property by means of the wall structure comprising many projecting ridges on the walls and to accomplish tight fitting between the container and the base cup.

An overhead transport carriage 1 comprises a body 4 containing an object 30 and traveling along a traveling rail 3, a lifting mechanism 6 including a holding unit 8 holding the object 30 and a lifting unit 7 moving the unit 8 up and down with respect to a predetermined position P at which the object 30 is contained, an anti lid-dropping-off member 20 facing a lid 31 of the object 30 when the unit 8 is located at the position P, and a moving mechanism. The mechanism 10 moves the member 20 in response to the motion of the unit 8 so that the member 20 is located at an anti dropping-off position when the unit 8 is located at the position P, and the member 20 is located at the escape position when the unit 8 moves with respect to the position P.
摘要:
For transferring an article to a desired position, even in a lateral transfer, a transfer system (100) allows transfer of an article (3) between a transport vehicle (2), which conveys the article (3) while travelling along a rail (1) provided on a ceiling, and a placement portion provided below the rail, in a lateral transfer manner. The transfer system includes a memory unit (101) and a controller (102). The memory unit stores (i) placement position information indicating a transfer position of the article when a transfer unit is to place the article onto the placement portion, and (ii) holding position information indicating a transfer position of the article when the transfer unit is to hold the article on the placement portion. The controller controls the transfer unit such that, when the transfer unit is to place the article, the article is transferred at a transfer position indicated in the placement position information and, when the transfer unit is to hold the article, the article is transferred to a transfer position indicated in the holding position information.
摘要:
The purpose of this invention is to prevent outside air from entering the bypass pipe portion when air is taken in the vessel for the prevention of a negative pressure, and thereby to secure normal, smooth liquid-discharging operation in the upside-down position of the vessel. For this purpose, the vessel equipped with a manual pump is also provided with a change-over valve unit 20 to switch the liquid supply to the manual pump 1 in response to the change in the posture of the vessel from the upright position to the upside-down position, and vice versa, so that the vessel can be used to discharge forcibly the liquid even in its upside-down position. In such a vessel, the channel taking outside air into the vessel 50 for preventing a negative pressure has an opening to the vessel 50 at the rear of the cap unit 40. The change-over valve unit 20 is attached to the cap unit 40 from downside in a posture tilted forward and downward so that the outside air rising to the liquid surface in the form of bubbles would not come close to the liquid intake slits of the change-over valve unit 20. It was also made easy for the check valve of the change-over valve unit 20 to sit stably on the valve seat.
摘要:
In a transport system, two drop prevention barriers and a drop prevention mechanism are provided along a periphery of a load port where a transported article has been placed. The drop prevention barriers and the drop prevention mechanism are arranged on three sides around the periphery of the load port and a remaining side is open along a first direction. The drop preventing mechanism includes a retaining member rotatably supported on a bracket. When a transported article moves along the first direction, the retaining member is pushed by a transport device such that it rotates from an initial position and retracts in an opposite direction from where a path is located. When the transported article has been loaded onto the load port, the retaining member returns to the initial position such that it is arranged slightly above the transported article.
