Definitions
- the invention relates to a device and a Nerfahr for manufacturing cups, in which the handles contained in a die are attached to the cup body.
- the handle is cast in a die casting mold and the handle attachments close after the die casting and removal of a third molded part in accordance with WO 99/10147 at the level of the die casting mold or slightly exceed it.
- WO 99/10147 describes a die-casting mold and a method for producing cups with prefabricated cup bodies, in which the handles are cast immediately prior to attachment to the cup body. The handles are attached to the cup body while they are still in the die. Only then is the die opened and the finished cup removed.
- the object of the invention is to provide a device and a method in which cups can be produced by machine throughout, despite the production-related fluctuations in the diameter and wall thickness of the cup bodies.
- the device for producing cups with prefabricated cup bodies in which the handles contained in a die casting mold are attached to the cup body, the handle attachments being at the height of the die casting mold or projecting slightly therefrom, is that a conveyor belt for moving the cup bodies and the Removal of the finished cups is provided that a limiting part is arranged on the transport, through which the respective cup body is given a defined position, that a lifting device for the cup body is provided on a linear guide above the conveyor belt, which is attached to a swivel arm which is in a precisely defined sequence of movements can be pivoted to the die with the handle contained therein.
- the lifting device can be made from a tube, through the vacuum to a suction plate for the cup body. is passed, as well as a coupling unit and a centering disc with a centering surface for the defined locking of the cup body on the lifting device.
- Another lifting device for defined suction or lifting of the cup body is also conceivable.
- the device for producing cups can have a vibrating device on the lifting device, the amplitude and the frequency of the vibrating device being advantageously adjustable.
- the vibration device which is provided for connecting the cup body and handle without a garnish slip, can be adapted to different casting materials and sizes.
- the coupling unit of the lifting device can largely be designed as desired.
- a disc clutch, a cone clutch or another clutch can be used.
- the method used with the devices comprises the following steps: a) moving the cup body up on a conveyor belt; b) placing a limiting part on the outer edge of the cup to which the handle is to be attached, which brings the cup body into a predetermined position; c) retracting a lifting device into the cup body, aligning the center surface on the side of the cup inner wall, on the cup outer edge of which the limiting part rests, and fixing the suction plate of the lifting device to the bottom of the cup body; d) moving the lifting device with the cup body over the die with the handle; e) applying gamers slip to the ends of the handle or to the corresponding locations on the outer edge of the cup to which the handle is to be attached; f) lowering the lifting device until the outer edge of the cup to which the handle is to be attached lies at a previously set distance above the die with the handle; g) generating a slight pressure of the lifting device until the cup body is connected to the handle; h) Opening the die and moving the lifting device back with the cup onto the conveyor belt.
- the procedure has the following steps:
- cups and other crockery parts in which certain function-related parts or decorative elements are to be subsequently attached to a base body, can be produced continuously by machine without reworking.
- the device enables the cup body to be picked up in a precisely defined position by the conveyor belt and then to be placed on the die casting mold by the lifting device at a precisely adjustable distance between the outside edge of the cup and the handles.
- a constant movement sequence can always be set for the swivel arm, since the cup body is removed from the transport bath in a defined position regardless of production-related fluctuations in the diameter of the cup body and the wall thicknesses.
- the device guarantees that the distance between the outside edge of the cup and the handle is always the same, which means that the cups are of uniform quality.
- the vibration device in a frequency range up to about 150 Hz and an amplitude up to 4 mm are switched on during the swiveling of the cup body via the die casting mold and are retained until the cup body and handle are connected to one another. This method results in seams between the cup body and the handle, which are no longer recognizable as such, since no Gamier slip is used to connect the cup body to the handle.
- this can be selected so that when the cup body is approximately horizontal over the die, the cup body is slowly shaken on the handle, so that the distance between the cup body and the handle approaches becomes practically zero. This process provides an extremely high quality of the connection points between the cup body and the handle.
- the process provides an integrated mechanical technology for the production of cups, jugs, etc., which ensures high quality of the products and eliminates manual reworking, such as repeated cleaning.
- the invention will be explained in more detail using an exemplary embodiment.
- the same reference numbers in the drawings denote the same or similar parts.
- Fig. 1 shows a device for making cups according to the present invention in plan view
- Fig. 2 shows a device corresponding to Fig. 1A from the side;
- Fig. 3 shows a cup body lying against a boundary part and the lifting device over the cup body;
- Fig. 4 shows the lifting device in the rest position;
- Fig. 5 shows the lifting device in the working position;
- Fig. 6 shows the lifting device with the cup body on the die with the handle contained therein.
- Fig. 1 shows a device for manufacturing cups 5 according to the present invention in plan view.
- a conveyor belt 1 is arranged between two mold stands 2, each mold stand 2 consisting of a row arrangement of several die casting molds 3, which are operated by a row arrangement of lifting devices 6.
- the lifting devices 6 carry finished cups 5 in this drawing.
- Reference number 7 denotes the swivel arms which carry and pivot the lifting devices 6.
- the reference number 8 designates the motors for pivoting the swivel arms 7.
- the swivel arms 7 are each moved together in the row arrangement of the lifting devices 6, but each swivel arm 7 is individually adjusted to the respective die 3.
- the lifting devices 6 lift a number of cup bodies 4, which corresponds to the number of die casting molds 3 in the mold stand 2, onto the die casting molds 3 and then, when the handles 9 are attached to the cup body 4, pivot the finished cups 5 back onto the conveyor belt 1.
- the finished cups 5 are located on the lifting devices 6 on one side of the conveyor belt 1.
- the die-casting molds 3 in this mold stand 2 are open.
- the die-casting molds 3 on the other side of the conveyor belt 1 are closed and contain the handles that were cast just before 9.
- the lifting devices 6 again take cup bodies 4 from the transport 1 and swivel them over the die casting molds 3 on this side of the conveyor belt 1.
- the opposing die casting molds 3 are cleaned during this time and prepared for the die casting of the next handle 9, and the next handles are poured.
- the production output of this machine is very high due to the arrangement of the mold stand 2 on both sides of the conveyor belt.
- Fig. 2 shows a device for manufacturing cups 5 according to the present invention in side view.
