A box-opening device is disclosed. The box-opening device includes a first holding part that holds a first surface and a second holding part that holds a second surface. The first surface is one of two adjacent surfaces of a folded corrugated cardboard sheet, and the second surface is the other of the two adjacent surfaces of the corrugated cardboard sheet. The box-opening device also includes a first holding part movement mechanism which changes a position of the first holding part with respect to the second holding part and thereby transforms the corrugated cardboard sheet into an opened state. The first holding part movement mechanism has a support member that supports the first holding part so that the part rotates on an arc track about a central axis of rotation that overlaps an imaginary line extending along a boundary line between the first surface and the second surface.

A lid forming device of a cardboard box using a first flap with a slit and a second flap to be extended after being bent into a mountain shape is disclosed. The lid forming device includes first and second folding mechanisms. The fist folding mechanism folds the first flap in a direction of closing the opening. The second folding mechanism bends the second flap into a mountain shape and inserts part of the second flap into the slit of the first flap while extending the second flap. The second folding mechanism includes first and second retaining units. The first retaining unit retains a first face of the second flap located between a free end of the second flap and a bend line set beforehand in the second flap. The second retaining unit retains a second face of the second flap located between an anchored end and the bend line.

Lid forming device

A cardboard box erector that folds four flaps provided on edges of an opening of a cardboard box so as to surround the opening is disclosed. The four flaps include a locking flap folded last among the four flaps. The cardboard box erector includes a folding unit configured to fold each of the four flaps in a predetermined order to close the opening, and a pushing unit configured to perform an action to push the locking flap inside the cardboard box and pull the locking flap back. The pushing unit has a suction unit configured to such and hold the locking flap.

Cardboard box erector

A box-making apparatus includes an electronic controller assesses abnormalities in the affixing of tape on the basis of a timing at which a cardboard box passes a detection position Pd, and a timing at which a tape roll starts or stops an action of unreeling the tape. The electronic controller assesses abnormalities in the affixing of tape also when there is a discrepancy of at least a predetermined amount between the timing at which the cardboard box passes the detection position and the timing at which the tape roll starts or stops the action of unreeling the tape.

Box-making apparatus

A push-in mechanism pushes articles into a box that is opened sideways. The push-in mechanism is provided with a box standby part, an article placement part, a push-in plate, a horizontal movement mechanism, and a lifting/lowering mechanism. The box standby part causes the boxes to wait. The article placement part has a placement surface on which the articles are temporarily placed. The push-in plate is installed in a standing state so as to have a pressing surface for pressing the articles toward the box. The horizontal movement mechanism causes the push-in plate to reciprocate horizontally above the placement surface so that the push-in plate moves toward the box or moves away from the box. The lifting/lowering mechanism moves the push-in plate so as to change a separation distance in the height direction between a lower edge of the pressing surface and the placement surface.

A packing apparatus includes a sealing mechanism, a timing sensing section, and a control section. The sealing mechanism affixes tape continuously on portions of a cardboard box transported with major flaps thereof folded. The sealing mechanism includes an affixing roller to press the tape against a first side surface and the major flaps. The timing sensing section senses the timing at which the affixing of the tape on the first side surface is initiated. The control section controls pressing force exerted by the affixing roller, based on a result of the sensing performed by the timing sensing section, in such a way that the pressing force is reduced after the affixing of the tape on the first side surface is initiated.

Packing apparatus

Provided is a highly reliable box-opening device being capable of suppressing failures of a box-opening action regardless of a size of a cardboard box sheet. The box-opening device unfolds a sheet in which first and second side surfaces and third and fourth side surfaces overlap, and forms a square-tube-shaped cardboard box. The box-opening device may have a suction disk to grasp the first side surface, a main arm having suction disks to grasp the fourth side surface and changing a posture while grasping the fourth side surface, and a control part to control a movement of the main arm so that an initial action, in which a gap is formed between the first and second side surfaces and the third and fourth side surfaces, and a main action that follows the initial action, are executed as an action of unfolding the sheet.

Box-opening device

A box packing system includes a frame, a cardboard sheet feeder, a box making section and a box packing device. The cardboard sheet feeder is configured to lift one of a plurality of cardboard sheets from a cardboard sheet stacking area of the frame. The cardboard sheets are in an upright state within the cardboard sheet stacking area and are folded or collapsed. The box making section re-shapes the cardboard sheet unfolding the cardboard sheet and transforms the cardboard sheet into a cardboard box where a bottom lid is closed and a top lid is opened defining an opening of the cardboard box. The box packing device has a dropping part that moves the cardboard box in a laterally opened state downwardly to s located filling position and a pushing part that pushes an article into the opening of the cardboard box while within the filling position.

Box packing device

A box packing device includes a dropping part configured to drops a laterally opened cardboard box in the state in which the lateral flaps of the cardboard box are open before and after dropping. The dropping part has an upper guide mechanism and a lower guide mechanism. The upper guide mechanism includes first upper guide portions that oppose front faces of the flaps and second upper guide portions that oppose rear faces of the flaps. The lower guide mechanism includes a first lower movable guide portion and a first lower fixed guide portion that oppose the front faces of the flaps, second lower guide portions that oppose the rear faces of the flaps, and a first drive unit for driving the second lower guide portions towards the first lower guide portion.

Apparatus for changing a position of device for measuring a weight of an object. The apparatus includes a conveyor portion, a measuring portion which also conveys the object and measures a weight of the object, and a pair of rails which extend along a conveying direction of the object and onto which the conveying and measuring portions are movably attached.
