A counter-ejector comprises: an elevator including a table displaceable in a forward-backward direction parallel to a feeding-out direction; a backward restriction member for restricting a situation where backward edges of corrugated paperboard sheets in a batch are displaced in a direction opposite to the feeding-out direction; table upward-downward movement drive device; a table displacement drive device; and a control device. The control device executes a table downward movement control processing such that the table is displaced backwardly in at least part of a time period when the table is moved downwardly from the hopper part to a table stop position and a time period when the table is stopped at the table stop position, and a table upward movement control processing such that the table is displaced forwardly in a time period when the table is moved upwardly from the table stop position to the hopper part.

A robot is configured such that: a second hand of a second arm holds a container stack by gripping a top portion of a bottom container of the container stack; then, a first hand of a first arm holds the container stack by gripping a portion of the bottom container of the container stack, such that the portion gripped by the first hand is positioned lower than the portion gripped by the second hand; thereafter, the second hand of the second arm releases the top portion of the bottom container, and then holds the container stack by gripping the top portion of a second container from a bottom of the container stack; and subsequently, the first hand of the first arm moves the bottom container downward, and separates the bottom container from the container stack.

A parts supply device includes a robot attachment member to be attached to a distal end portion of a robot arm, a parts holding tool supported by the robot attachment member, a stick mounting unit supported by the robot attachment member and on which a stick containing parts is mounted, a parts discharging mechanism which discharges, one by one, the parts contained in the stick mounted on the stick mounting unit, a guide member that guides the parts discharged by the parts discharging mechanism to a holding position by a holding member of the parts holding tool, and a relative movement device that moves the guide member in a state where one of the parts is held by the holding member to allow the one of the parts held by the holding member to be mounted on a predetermined position.

A method for operating a tray conveying apparatus, wherein a tray edge of a tray to be destacked is guided in contact with and along a support until the tray has been deposited on a conveying unit positioned therebelow. An apparatus for destacking and further conveying trays that may comprise a destacker for destacking trays, wherein the destacker may also comprise a frame for accommodating at least one tray stack and a plurality of destacking screws configured to be operated in a respective direction of rotation. Each destacking screw may comprise a helically configured spiral or groove with a support. A conveying unit may be positioned below the destacker and used for receiving and transporting the destacked trays from the destacker.

A device for quickly deploying and collecting visible markers is disclosed. Visible markers can include a base that can support an upright flag for use in sports training, marketing, or traffic/emergency situations. The device for retaining the bases can be comprised of a frame having two vertical legs joined by a horizontal member, which can serve as a handle, at a top portion of each of the two vertical legs. A foot is attached to the bottom end of each of the two vertical legs, each of the feet are at an angle to the corresponding vertical leg to allow feet to be received in apertures of a base device and the angle of the feet retain the base device on the frame.

Provided are a guide hopper and an apparatus for manufacturing secondary battery including the same. The guide hopper includes a guide space adjusted by movement of a corner member defining the guide space. The guide hopper includes a housing, in which an inner space having upper and lower portions is defined, and a variable assembly disposed in the inner space of the housing. The variable assembly includes four corner members of which bent inner sides define a guide space having a rectangular shape. The size of the guide space is adjustable by movement of the corner members in a first direction or in a second direction perpendicular to the first direction.

A parts supply device includes a robot attachment member to be attached to a distal end portion of a robot arm, a parts holding tool supported by the robot attachment member, a stick mounting unit supported by the robot attachment member and on which a stick containing parts is mounted, a parts discharging mechanism which discharges, one by one, the parts contained in the stick mounted on the stick mounting unit, a guide member that guides the parts discharged by the parts discharging mechanism to a holding position by a holding member of the parts holding tool, and a relative movement device that moves the guide member in a state where one of the parts is held by the holding member to allow the one of the parts held by the holding member to be mounted on a predetermined position.

A facility having a main space under vacuum, at least one device for transferring objects between a zone at atmospheric pressure and a zone under vacuum, a device (30) for unstacking/stacking objects, a device for conveying objects and support elements (24, 25) for supporting each object, these being secured to the conveying device. Each transfer device has a frame and a transfer member, provided with at least one cell (C1-C4) that accepts at least one object that is to be transferred. The frame defines a first opening in communication with the zone at atmospheric pressure, a second opening in communication with the zone under vacuum, and an intermediate region intended to be placed either under vacuum or at atmospheric pressure.
