A method for transporting articles () to a station, in particular preforms to a blow-molding apparatus, wherein each article has a protrusion () and is moved along a guide () by a drive means (), the article (), along at least part of the guide (), should be retained on an abutment (), and advanced along this abutment, by an air stream.

Method and apparatus for transporting articles to a station

The invention relates to a method for transferring hollow cylindrical objects from a supply unit to a removal unit by providing a transport unit for transferring hollow cylindrical objects between a supply unit and a removal unit, providing at least holding element in the transport unit, positioning the hollow cylindrical object in contact with the at least one holding element at the supply unit wherein the hollow cylindrical object is held by the holding element, moving the transport unit with the hollow cylindrical object from the supply unit to the removal unit, and removing the hollow cylindrical element from the at least one holding element at the removal unit.

Device and method for discharging elongate, coarse bulk products and for their further transport

A device is disclosed for discharging elongate, coarse bulk products&#x2014;such as bottle preforms&#x2014;from a product hopper. The device includes a product hopper with a discharge opening and a rotating disc that is configured to receive bulk products passing through the discharge opening.

Disclosed is a device for conveying pro-filled objects, particularly bottles or parisons comprising an annular collar between two sliding planes with the aid of at least one conveying apparatus, at least one part of which rests against the object in a frictionally engaging manner and is supported on receiving elements or pressure rollers. The part of the conveying apparatus that rests against the object in a frictionally engaging manner is resilient or is mounted in a resilient fashion.

Device for conveying objects

A tool store device comprises a stnad having a base and a support frame on which is supported a tool carrier. The tool carrier is constructed as a semi-spherical shell which is rotatable about a horizontal axis and carries tools which are densely arranged thereon with their longitudinal axes extending at right angles to the store surface. On the inside of the tool carrier there is positioned an advance unit having a displacement unit and a gripper which are rotatably mounted in the support frame about a vertical axis passing through the center (M) of the imaginary ball of which the semi-spherical shell of the tool carrier is the part. The advance unit cooperates with a tool changer, which has a swivel arm swivellable about the horizontal axis. A tool double gripper is fixed to the arm. The advance unit can advance a tool at a random point of the tool carrier to a transfer station, where it can be taken over by the double tool gripper. The swivel arm brings the double gripper at the transfer station into the vicinity of a work spindle of a machine tool, where the tool is inserted into the spindle from the tool double gripper. The tool is taken back from the work spindle in the reverse order by the tool gripper, which transfers the tool to the advance unit at the transfer station of the tool store device.

Tool store for machine tools

A tool rack includes a rotor mounted in a rotary manner on a column and carrying on its circumference tool magazines in a tight, uninterrupted arrangement over the entire circumference thereof, so that there is no possibility of access for a tool interchanger to the individual tools. A displacement unit with displacement arms positioned above and below the rotor is used for the access to a tool. The displacement arms have magazine grippers which grip a desired, displayed magazine, and advance it over the length of the tools of the adjacent tool holders. By means of the tool interchanger it is now possible to grip the desired tool and bring it to a use point. The rotor thus can be provided with a maximum number of tools, but still permits a very rapid tool exchange, which is particularly advantageous in the case of single-spindle working machines.

Tool rack for machine tools

A mobile storage and transportation unit for machine tools employing a frame rack having at least one frame, the frame being provided with at least one chassis engaging device. The unit also employs a plurality of elongated tool storage magazines, each magazine having an elongated front face and an opposite elongated rear face and having opposite ends. The front face of each magazine is adapted to removably receive and store a plurality of tools in adjacent side by side positions, the tools being disposed along a common row. The unit also employs a like plurality of chassis, each chassis being secured to the rear face of a corresponding one of the magazines adjacent a corresponding one of the two opposite ends thereof. All of the chassis engage the chassis engaging device to suspend the magazines in parallel abutting position on the frame.

Storage and transportation unit for machine tools

A rotor having an upper and a lower track is rotatably mounted on a column. Tool magazines equipped with running devices are mounted on the tracks. On a store frame is fixed a first gripper mechanism having second lifting units enabling a selected tool magazine to be blocked on the rotor and brought into the loading and unloading position. A second gripper mechanism is mounted on the rotor and is used for seeking a selected tool magazine, for securing it to the rotor and bringing to the first gripper mechanism. By forming a magazine free section on the rotor, a display arm and a loading and unloading station can be used to remove tools from the store and return them again. By using a further display arm, tools can be changed manually or by means of a portal loader during the machining time. As only one magazine-free section is required for loading and unloading, the store can have a much a higher store capacity than known stores.

Tool store for machine tools and method for the operation thereof

A textile machine is provided with a movable transport conveyor having Casablanca pins which convey packages on bobbins and a support member located in the path of movement of the bobbins for release of the bobbins from the pins. The support member serves to push the bobbins relative to the pins in order to effect a release of the bobbins from the pins. In addition, the support member cooperates with a transport conveyor which permits the released packages to be taken off to further processing equipment.

Apparatus for handling textile bobbins

The bobbin for receiving a roving has an internal shoulder enabling it to seat on a surface provided at the upper end 5 of a spindle. The bobbin hangs from this shoulder and the bottom of the bobbin is received in a resilient clamping means provided on the spindle for clamping a roving end against the bobbin.

Tension is reduced in the unwound length of roving remaining between the drafting mechanism and the package after the frame has been brought to a halt. This can be done by additional feed from the drafting mechanism after stopping of the other elements of the frame. A tension adjusting means is coupled into the drive to the rollers of the drafting mechanism to advance the mechanism the desired amount. The degree of feed may be different depending upon whether the stoppage is due to a break at one of a group of flyers, or to a doffing operation.
