Description

Field of the Invention

[0001] The present invention relates to an apparatus and a method for manufacturing plastic preforms. Background Art

[0002] Such apparatuses and methods have long been known from the prior art. For example, injection molding machines or injection blow molding machines are used to manufacture this type of plastic preform, for example made of PET. In the apparatuses and methods known from the prior art, plastic preforms are usually manufactured in a separate operation and then further processed with other machines such as stretch blow molding machines to form containers.

[0003] Recently, efforts have also been made to integrate the manufacturing process of plastic preforms into the corresponding container handling equipment. This has the advantage that, due to the manufacturing, the manufactured plastic preforms are hot, and thus, if required, energy for further heating the plastic preforms can be saved.

[0004] In the prior art, it is not common to monitor injection molding machines. After the injection molding process, the manufactured plastic preforms are usually further transported in grid boxes or octabins or on conveyor belts without inspection. Therefore, it is currently not known how to monitor injection molding machines to identify possible failures of individual injection mold cavities at an early stage.

[0005] DE 10 2000 1618 670A1 discloses a method and an apparatus for testing plastic preforms. The plastic preforms are transported on a conveyor belt and inspected when transferred from one conveyor belt to another.

[0006] WO 2018 / 036857 A1 discloses an optical inspection system for plastic preforms. In this case, the plastic preforms are inspected with at least one camera device such that the plastic preforms are in a fixed relative position with respect to the injection molding operation.

[0007] DE 602 8 756T2 also discloses a method and an apparatus for processing ejected injection molded parts. Summary of the Invention

[0008] The object of the present invention is to perform monitoring, in particular for apparatuses for manufacturing plastic preforms, such as injection molding machines or injection blow molding machines. According to the present invention, this object is achieved by the subject matter of the independent patent claims. Advantageous embodiments and improvements are the subject matter of the dependent claims.

[0009] The device for manufacturing plastic preforms according to the invention comprises a manufacturing device having a plurality of manufacturing units and / or cavities, wherein each of the cavities is adapted and used for manufacturing plastic preforms, and wherein the plastic preforms are each configured as a monolithic body and have at least one base body and a threaded portion provided on the base body.

[0010] Furthermore, the device comprises a removal device which is adapted and used for removing, in particular together, the plastic preforms manufactured by the manufacturing device from the manufacturing device. Furthermore, the removal device comprises a carrier which is adapted and used for holding the removed plastic preforms, and a transport device which is adapted and used for transporting the carrier together with the plastic preforms removed from the removal device in a predetermined transport direction, wherein the device comprises an inspection device for inspecting the manufactured plastic preforms.

[0011] According to the invention, the inspection device comprises at least one infrared image recording device which is adapted and used for recording a spatially resolved image of at least one region of a plurality of manufactured plastic preforms.

[0012] Therefore, within the scope of the present invention, it is proposed that the inspection of the plastic preforms has been carried out in the manufacturing device and / or within the scope of the manufacturing process.

[0013] In this way, with the aid of the inspection device, in particular an infrared measurement system, the plastic preforms can be monitored directly after the manufacture or injection molding of the plastic preforms, and possible temperature differences can preferably be identified, which can be attributed to wear and / or defective cavities, heaters or defective cooling units or defective injection molding processes of corresponding quality.

[0014] Therefore, with the help of this infrared monitoring, faults in the injection molding machine can be detected and corrected in advance or at an early stage, in particular before the faults occur. Furthermore, defective injection-molded plastic preforms can be identified and preferably ejected.

[0015] Preferably, the infrared image recording device and / or its assigned evaluation device is adapted and used for outputting at least one measured value characterizing a physical property (e.g., its temperature) of the plastic preform. For example, the temperature of the plastic preform can be inferred from the recorded image.

[0016] Particularly preferably, the carrier is adapted and used for holding the plastic preforms at least partially in positions equidistant from each other, in particular also in parallel alignment (with respect to each other). Thus, for example, the carrier can have a plurality of openings, each of which is adapted and used for recording plastic deformation. These openings can be arranged in an array.

[0017] In a preferred embodiment, the device comprises a receiving device which is adapted and used for receiving the plastic preforms from the carrier.

[0018] In this case, the receiving device preferably comprises a plurality of receiving units, which are adapted and configured to receive individual plastic preforms from the carrier, respectively. In this case, these receiving units can be, for example, vacuum grippers, which are adapted and configured to receive plastic preforms. Thus, the receiving device preferably has receiving elements that are controllable independently of one another and are adapted and configured to receive plastic preforms, respectively. As described above, these are preferably vacuum grippers, which can be placed respectively on the mouths of the plastic preforms.

[0019] In another advantageous embodiment, the infrared image recording device is adapted and configured to detect radiation in a wavelength range from 4000 nm to 20000 nm, preferably in a wavelength range from 6000 nm to 8000 nm, and particularly preferably in a wavelength range from 8000 nm to 15000 nm.

[0020] In another preferred embodiment, the infrared image recording device is adapted and configured to output a value characterizing the temperature of the plastic preform, and preferably is adapted and configured to output at least one value characterizing the temperature thereof for each inspected plastic preform. Thus, the infrared image recording device and / or the evaluation device is preferably adapted and configured to output a plurality of measured values, which preferably at least correspond to the number of plastic preforms being transported.

[0021] Preferably, each of these measured values is assigned to and / or will be assigned to at least one and preferably exactly one manufactured plastic preform.

[0022] To this end, the inspection device can comprise an evaluation device for evaluating the recorded images, which preferably detects and / or identifies each plastic preform recorded by the infrared image recording device. Preferably, for each of these plastic preforms, a measured value characterizing a measured value such as the temperature of the plastic preform is detected.

[0023] This is also particularly achievable because the infrared image recording device preferably has a predetermined and also fixed position relative to the carrier on which the plastic preforms are mounted.

[0024] In the measurement of the physical quantities described here, especially the temperature of the plastic preform, emissivity is also an important factor. It depends on various influences and can thus be adjusted according to the application for manufacturing plastic preforms. For example, plastics with a thickness greater than 0.4 mm can be measured very well in the dark infrared spectral range (8000 nm to 14000 nm) with an emissivity greater than 0.9.

[0025] Preferably, the inspection device has a calibration device, which is adapted and configured to calibrate the infrared image recording device, especially taking into account the plastic preforms that have been manufactured and / or are to be manufactured.

[0026] In this case, the inspection device can have a planar camera, but a line camera can also be used. One or more images can also be recorded and unfolded to a predetermined angle, for example, an angle of at least 180°, preferably at least 360°.

[0027] Preferably, the inspection device is arranged to be adapted to and for inspecting at least partly and preferably precisely partly the plastic preforms held by a carrier (for example, in the threaded area of the plastic preform or in the area of the (to be expanded) matrix of the plastic preform).

[0028] In another advantageous embodiment, the inspection device is arranged to be adapted to and for inspecting the plastic preforms held by a receiving device.

[0029] In this case, the inspection device can inspect a predetermined area of the plastic preform, such as its mouth or its matrix.

[0030] In another advantageous embodiment, the device includes a distribution device which is adapted to and for allocating the manufacturing unit and / or the mold cavity for manufacturing the plastic preforms to the plastic preforms inspected by the inspection device. Due to this particularly clear allocation, more precise control and / or adjustment of the manufacturing device is preferably also possible, as described below.

[0031] In another advantageous embodiment, the device includes a control device for controlling the manufacturing device, which is preferably adapted to and for controlling each of the manufacturing units. In this way, the manufacturing device can be controlled individually, especially adjusted.

[0032] Preferably, the control device is adapted to and for controlling, especially adjusting the manufacturing device and / or the individual manufacturing units (respectively) according to at least one measured value.

[0033] Preferably, the control device is adapted to control and / or adjust at least one parameter characterizing the operation of the manufacturing device and / or the manufacturing unit, preferably a plurality of parameters.

[0034] Preferably, these parameters are selected from a group of parameters which includes the needle closing time, injection delay, time behavior of the injection (plastic composition), pressure distribution, holding pressure, especially the pressure distribution of the holding pressure and the duration of the holding pressure, cooling time, etc.

[0035] In addition, the parameter can also be at least one temperature, especially the temperature of the mold cavity for manufacturing the plastic preform, the temperature of the nozzle, especially the temperature of the injection nozzle for the plastic composition, the temperature of the hot runner or the temperature of one or more heating zones for plasticization.

[0036] Furthermore, the parameter can also be selected from a group of parameters which includes the rotational speed of the (delivery) screw, the dynamic pressure of the melt or the position and / or pressure of the closing unit (especially during injection molding).

[0037] In particular, the adjustment can be made according to the temperature value of an individual plastic preform measured by an infrared image recording device.

[0038] In another preferred embodiment, the (infrared) inspection device is also adapted to and used for detecting said physical value of each plastic preform with spatial resolution.

[0039] Thus, preferably, for example, not only can the temperature of an individual plastic preform be determined or derived, but also this temperature can be determined with spatial resolution according to the plastic preform (and / or relative to the plastic preform), for example, it can be detected that certain areas of the thread are colder than other areas.

[0040] Particularly preferably, the individual manufacturing units are controlled according to the recorded images, especially the derived temperature values. Thus, for example, an individual manufacturing unit can have a separate heating device which is controlled and / or controllable independently of each other accordingly. For example, the contact pressure in the manufacturing unit can also be controlled. Furthermore, for example, the material distribution of the plastic material supplied to the manufacturing unit can also be affected.

[0041] In another advantageous embodiment, the device includes a cooling device which is adapted to and used for at least segmentally cooling the plastic preforms manufactured by the manufacturing device. This cooling device is also preferably integrated into the manufacturing process. Particularly preferably, the plastic preforms are removed and / or transported only after they have been cooled or after an individual plastic preform has been cooled.

[0042] The cooling device is also preferably controllable and particularly controllable according to the inspection results of the inspection device and particularly adjustable.

[0043] Furthermore, such cooling can be carried out before the plastic preforms are removed from an individual manufacturing unit, or preferably after they are removed from an individual manufacturing unit. Thus, for example, the cooling device can cool the plastic preforms located in the carrier. In this case, the cooling can be carried out, for example, by acting on the plastic preforms with air or a coolant. Cooling by convection is also possible.

[0044] In another preferred embodiment, the manufacturing device has a plasticizing unit. This can include an injection molding unit adapted to inject a plastic composition. The injection molding unit preferably has a delivery screw for delivering the plastic composition and preferably has a nozzle connected to the delivery screw.

[0045] Furthermore, the manufacturing apparatus has at least one material supply device, which is adapted and used to supply plastic material, particularly plastic material in granular form.

[0046] In another preferred embodiment, the manufacturing apparatus has a drying device for drying the plastic granules to be supplied.

[0047] In another preferred embodiment, the apparatus includes a second inspection device for inspecting the manufactured plastic preforms, wherein the second inspection device includes at least one image recording device, preferably at least one infrared image recording device, which is adapted and used to record at least one spatially resolved image of at least a second region of a plurality of manufactured plastic preforms.

[0048] In this case, the second inspection device can also be implemented in the above-described manner, thereby also omitting the repetition of the above individual features.

[0049] The manufacturing apparatus can also be controlled based on the values output by the second inspection device (particularly based on the measured temperature of the plastic preforms).

[0050] In another advantageous embodiment, the apparatus has another inspection device for inspecting the manufactured plastic preforms. This can be, for example, an image recording device that records a spatially resolved image of the plastic preform in each case, and in particular, the image recording device is not an infrared image recording device, but a camera or an image recording device that records images in the visible light wavelength range.

[0051] The other image recording device can be used, for example, to detect defects on individual plastic preforms, such as an incompletely formed mouth or hole of a container, etc.

[0052] Preferably, the above-described dispensing device is also adapted and used to separately assign the plastic preforms recorded by the other image recording device to those manufacturing units that manufacture these plastic preforms.

[0053] Preferably, the manufacturing apparatus can also be controlled by considering the measured values output by other inspection devices.

[0054] Preferably, the apparatus further includes a lighting device for illuminating the plastic preforms inspected by the other inspection device.

[0055] The present invention also relates to a method for manufacturing plastic preforms, including a manufacturing apparatus having a plurality of manufacturing units and / or cavities, wherein each of the manufacturing units and / or cavities manufactures a plastic preform, and wherein the plastic preforms are each configured as an integral body and have at least one base and a threaded portion provided on the base.

[0056] In addition, the device includes a removal device that removes the plastic preforms manufactured by the manufacturing device together, wherein the removal device includes a carrier for holding the removed plastic preforms. Further, a transport device is provided that transports the carrier and the plastic preforms removed from the removal device along a predetermined transport direction, wherein the device includes an inspection device that inspects the manufactured plastic preforms.

[0057] According to the invention, the inspection device includes at least one infrared image recording device that is adapted and configured to record a spatially resolved image of at least one region of a plurality of manufactured plastic preforms and to output at least one value characterizing a physical property, preferably the temperature, of the inspected plastic preform.

[0058] Particularly preferably, the infrared image recording device records an image of the plastic preform immediately after the plastic preform has been removed and / or during transportation by the first transport device. In this case, the infrared image recording device can record an image during the movement of the plastic preform and / or the transport device.

[0059] Particularly preferably, the evaluation device evaluates the recorded images in such a way that values characterizing the plastic preform, and in particular values characterizing its temperature, are assigned to each detected plastic preform.

[0060] Particularly preferably, the manufacturing device or individual manufacturing units of the manufacturing device are controlled and in particular adjusted taking into account these measured values recorded for each individual plastic preform.
