A tool holder () defines three stop surfaces (), which lie in three planes (), which are perpendicular to each other. A pin (), which can be lowered into the base body () of the tool holder () and extended from it, is to be introduced into a receptacle () of the tool () and comprises a slanted active contact surface (), which defines a fourth plane (), which intersects each of the three planes () of the tool holder () at an acute angle, as a result of which the active pressure surface (), upon the extension of the pin (), exerts a force component toward each of the three stop surfaces (). A corresponding tool () and a workstation with the tool holder () and the tool () attached thereto are also described.

An unloading and erecting apparatus has a frame fixed to a magazine holding a stack of flattened cartons, an outer horizontal guide on the frame, an outer horizontal slide horizontally displaceable on the outer horizontal guide and carrying a nonstraight outer vertical guide. A drive motor connected to the outer horizontal slide horizontally displaces same. A vertical guide on the frame carries a vertical slide and another drive motor connected to the vertical slide vertically displaces same. A shaft pivotal about a generally horizontal axis transverse to the forward direction on the vertical slide is fixed horizontally relative to the outer horizontal slide. A gripper fixed on and angularly displaceable with the shaft is engageable with the frontmost carton of the stack and carries a lever angularly coupled to the gripper and having offset from the axis a follower engaged in the vertical guide of the outer slide for, on vertical movement of the vertical slide, pivoting the gripper between a pick-off position engageable with the frontmost carton and a drop-off position directed downwardly above the conveyor.

Carton unloading and erecting apparatus

An apparatus for the insertion of products of various sizes from a product conveyor into containers on a container conveyor has an insertion chain of carriages whose rams are controlled by endless cams along the carriage travel path. The hold-down tongues on hold-down rods are mounted on slides which are guided on posts of the carriages and controlled by a slide cam and a rod cam on a cam carrier which is split for size adjustment upon movement of a moveable carrier to vary the positions of these cams at the insertion region of the chains when products of different sizes are to be inserted in the boxes.

Apparatus for the simultaneous introduction of product and packaging

A system for erecting boxes has a magazine holding supply of flattened boxes having panels separated at respective fold lines, a support wheel generally continuously rotating about an axis adjacent the supply, a grab on the support wheel, an unfolder on the wheel adjacent the grab, and a conveyor adjacent the wheel. The grab and the unfolder are pivotal on the wheel about a grab axis parallel to the wheel axis and defining thereabout an orbit and the conveyor has upper and lower elements defining parallel and vertically spaced upper and lower conveyor planes, and front and rear elements displaceable parallel to the planes therebetween and defining respective conveyor calls. The upper plane is generally tangent to the orbit of the grab axis. A box is engaged with the grab and with the unfolder which are then relatively pivoted about the grab axis until the box is erected and an upper panel of the erected box engaged by the grab extends parallel to the upper conveyor plane but is spaced above the upper conveyor plane. Thereafter the grab and unfolder are synchronously pivoted about the grab axis while rotating the wheel to maintain the upper panel of the box parallel to the upper conveyor plane until the upper panel lies generally on the upper conveyor plane. The box is then released from the grab into a respective cell of the conveyor.
