A supply apparatus that supplies corrugated cardboard sheets to a supply position in a box-making section that opens folded corrugated cardboard sheets and makes boxes. The supply apparatus comprises a conveying unit, a drive unit, and a control unit. The conveying unit conveys a plurality of the corrugated cardboard sheets to the supply position with the corrugated cardboard sheets stacked. The drive unit drives the conveying unit. A controller, serving as the control unit, estimates the total quantity of the plurality of stacked corrugated cardboard sheets on a conveying surface of the conveying unit. The controller acquires a value pertaining to the drive force of the drive unit when the drive unit drives the conveying unit, and estimates the total quantity of the plurality of stacked corrugated cardboard sheets on the basis of the acquired value.

Supply apparatus

A box packing device includes a push-in mechanism, a retention mechanism, a guide, and a control unit. The push-in mechanism pushes, into a box that is in a state in which an opening thereof faces sideways, the article through the opening. The retention mechanism retains the box that is in a state in which the opening faces sideways and lowers the box after the article have been pushed into the box by the push-in mechanism. The guide opposes the opening and is configured to prevent the article from falling out from the opening of the box that has been lowered by the retention mechanism. The control unit temporarily increases the distance between the box and the guide after the article have been pushed into the box by the push-in mechanism.

Box packing device

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

Provided is a boxing apparatus that pushes a plurality of articles into a box, whose opening may face sideways, from the side and, thereafter, change the posture of the box by rotating the box so that the opening faces upward, wherein the possibility that the articles fly out of the box when changing the posture is reduced and the posture of the box can be changed in a short period of time. The boxing apparatus may include a push-in mechanism, a holding and posture changing mechanism, and a guide/holding member.

Boxing 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.

Push-in mechanism and box packing device provided with same

Provided is a boxing apparatus that may repeatedly push products packaged in a soft packaging material into a box through a lateral opening and to pack the products in a plurality of rows, wherein product-filled rate may be easily enhanced without damaging the products. A boxing apparatusmay pack a plurality of rows of bagged products into a box. The boxing apparatus may be provided with a push-in mechanism, a shutter, a vertical movement mechanism, and a controller. The push-in mechanism may push the products into the box through a lateral opening in the box. The shutter may enter and exit the box through the opening. The vertical movement mechanism may move the box and the shutter up and down relative to each other.

A box packing apparatus supports a box with a sideways facing opening while at a loading location. After loading the box is moved from the loading location. The box packing apparatus includes a supporting and moving component, arms, and a feed mechanism. The supporting and moving component supports the cardboard box in the loading location and moves the cardboard box after loading in the loading location. The arms temporarily support the cardboard box as it is delivered to the loading location with the opening thereof facing sideways, while the supporting and moving component moves the cardboard box. The feed mechanism feeds the articles into the cardboard box through the opening while the box is supported by the arms.

Box 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 boxing apparatus erects packages that can be erected along a limited section of a conveyor, without having to erect them all at once, even with individual packages that are long in the feed direction. The boxing apparatus has a fourth conveyor belt that blocks the front of a line of incoming packages and exerts an upward force on the front package. The front package is raised up by this upward force, so the following package rides up onto the package in front, and the packages are erected successively. Consequently, even individual packages that are long in the feed direction can be erected at a limited section of a third conveyor belt.

A packaging apparatus includes a collection unit and a conveyance unit. The collection unit is configured and arranged to overlay a plurality of packaged objects on adjacent packaged objects. The conveyance unit is configured and arranged to convey, as a group of packaged objects, the packaged objects which are overlaid on the adjacent packaged objects at the collection unit. The conveyance unit includes a position control component. At least one portion of the position control component is positioned below a conveyance plane of the conveyance unit and the other portion of the position control component is positioned above the conveyance plane of the conveyance unit before positions of the packaged objects are adjusted, the one portion and the other portion of the position control component is provided sequentially.

Packaging apparatus

An article alignment device aligns articles having first end portions and second end portions that have a shape different from the shape of the first end portions. The article alignment device includes a first conveyance device, a second conveyance device, and a control device. The first conveyance device has conveyance units that carry and convey the articles. The first conveyance device conveys the articles in a first orientation. In the first orientation the first end portions are positioned on a downstream side with respect to a first conveyance direction of the articles. The second conveyance device is placed downstream of the first conveyance device. The control device controls the first and second conveyance devices such that the orientation of first articles conveyed by the second conveyance device are changed to a second orientation where the second end portions are positioned on the downstream side.
