In a particularly preferred embodiment of the invention each blow moulding unit includes a defect input station adjacent to the moulded product finishing station for operator input of reject data; each blow moulding machine includes an associated monitoring and control unit; and the apparatus includes a central control and monitoring unit for monitoring data from the defect input station and the monitoring and control unit associated with each blow moulding machine.
In one embodiment of the invention the moulded product finishing station includes a final trimming apparatus which comprises a holding bed for receiving a blow moulded article to be trimmed; clamping means for clamping a blow moulded article in the bed; and heating means for applying heat to the rough edges of the article to smooth the rough edges and produce a finished article having a smooth edge finish.
In this case, preferably the heating means is provided by a plurality of heating jets and the apparatus includes means for moving the holding bed relative to the heating jets to present rough edges of the article clamped in position in the holding bed to the heating jets for smoothing.
In a preferred embodiment of the invention the means for moving the holding bed comprises a first ram means which is operated to move the holding bed from a loading position to receive a moulded article to be trimmed to a position below the heating jets, and a second ram means for moving the holding bed with the moulded article in place into a trimming position adjacent to the heating jets .
The invention also provides a method for manufacturing blow moulded articles utilising the apparatus of the invention, the method comprising the steps of:delivering a mould from a common mould storage area through a common mould transfer area to one of a number of separate blow moulding machines; delivering virgin raw material from a common mould services area into a blending means; regrinding waste material from a moulded product finishing station associated with the blow moulding machine; delivering the regrind material into a regrind holding unit; delivering regrind material from the regrind holding unit into the blending means; delivering colorant material from the common mould and colorant material holding area into the blending means; delivering the blended material to the blow moulding machine; blow moulding a plastics article; removing the moulded plastics article from the blow moulding machine; finishing the moulded plastics article producing waste material; inspecting the article for defects; delivering the finished article to a staging area adjacent to the blow moulding unit; and shipping the finished article through a shipping area having an outlet dedicated to the particular blow moulding machine in which the article was moulded.
In a particularly preferred embodiment of this aspect of the invention a method includes the steps ofx~ recording defects detected on inspection of moulded articles at a defect input station; monitoring the operation of the moulding machine using a monitoring and control unit; and monitoring data from the defect station and the machine monitoring and control unit to provide operating data on each individual moulding machine.
In a preferred embodiment of the invention the method includes the steps of:· placing a blow moulded article in a holding bed; clamping the article in position in the holding bed; delivering the holding bed with the article clamped in position to heating jets; and heating the edges of the article to smooth the edges.
The invention also provides a blow moulded plastics article whenever produced using the apparatus or method of the invention.
The invention will be more clearly understood from the following description thereof given by way of example only with reference to the accompanying drawings in which;Fig. 1 is a plan view of an apparatus for manufacturing blow moulded articles according to the invention; Fig. 2 is a diagrammatic plan view of one moulding unit forming part of the apparatus; Fig. 3 is a perspective view of a final trimming apparatus used in the method and apparatus of the invention in one position of use; and Fig. 4 is a perspective view of the trimming apparatus of Fig. 3 in another position of use.
Referring to the drawings and initially to Fig. 1 thereof there is illustrated an apparatus for manufacturing blow moulded articles indicated generally by the reference numeral 1. The apparatus 1 comprises a plurality individual blow moulding units 2 which are transversely arranged and spaced-apart in a single row. The apparatus 1 includes a common mould and colorant storage area 3, a common mould transfer area 4 and a common moulding unit services header 8 The services area 8 includes central lines for virgin plastics material, process and cooling water and compressed air for operating the blow moulding machines. The apparatus includes a finished product staging area 5 having a number of regions 5A of the staging area 5, one region being associated with an adjacent blow moulding unit 2.
The apparatus 1 also includes a finished product shipping area 10 having a plurality of separate shipping outlets 11, each shipping outlet 11 being associated only with an adjacent region 5A of the finished product staging area 5 for one blow moulding unit 2. The finished product is discharged through the shipping outlet 11 to container trucks 12.
It will be noted that the mould storage area 3, the mould transfer area 4, the moulding unit services area 8, the finished product staging area 5 and the finished product shipping areas 11 all extend substantially longitudinally parallel to one another and the moulding units 2 extend transversely between the services area 8 and the staging area 5.
In more detail and referring to Fig. 2 each blow moulding unit 2 comprises a blow moulding machine 20 with a moulded product finishing station 21 from which finished inspected plastic articles are delivered along line 22 into the staging area 5. Flash material and any defect articles are delivered along line 23 from the finishing station 21 into a regrinding unit 25 which delivers reground plastics material into a regrind holding unit 26 which holds only regrind material associated with a particular blow moulding machine 20.
The blow moulding unit 2 includes a raw material blending unit 30 in which raw virgin plastics material is delivered by vacuum from the services header 8 along a line 31, regrind material is delivered from the regrind holding bin 25 along the line 32, and desired colorant material is delivered from the mould storage and colorant storage area 3 along the line 33.
The blow moulding unit 2 also includes a defect input station 40 at which an operator inputs information regarding any defects generated by the machine 20. The input may be by means of a bar code scanning device for ease of operation. Each blow moulding machine 20 also has an associated monitoring and control unit 41 and data from the defect monitoring unit 40 and the machine monitoring and control, unit 41 are picked up by central control and monitoring unit which monitors all the relevant control data from each of the blow moulding units 2. In this way, the operation of each individual blow moulding unit 2 can be readily monitored remote from the moulding units so that any deviations from the norm are notified within a very short time span. This leads to optimisation of the operation of all of the blow moulding units.
Because of the arrangement of the various parts of the apparatus for manufacturing blow moulding articles there is minimum handling of raw materials and finished blow moulded plastic articles. Each blow moulding unit 2 operates independently of other similar units while sharing common raw material sources. In this way each of the blow moulding machines may be used to produce the same blow moulded articles or some may produce different articles without interference from one machine to another. This gives very high manufacturing efficiency and flexibility.
Each blow moulding unit 2 also includes a final trimming apparatus 49 which is shown in more detail in Figs. 3 and 4. Referring particularly to Figs. 3 and 4 the final trimming apparatus 49 comprises a holding bed 50 for receiving a blow moulded article to be trimmed, clamping means 51 for clamping the article in position in the holding bed 50 and heating means provided in this case by a plurality of heating jets 52 for applying heat to the rough edges of the article to smooth the rough edges and produce a finished article having a smooth edge finish.
The trimming apparatus 49 includes means for moving the holding bed relative to the heating jets 52 to present any rough edges of an article clamped in position in the holding bed 50 to the heating jets 52 for smoothing. In this case, the means for moving the holding bed comprises a first ram means 55 which is operated to move the holding bed 50 from a loading position illustrated in Fig. 3 to receive a moulded article to be trimmed to an intermediate position below the heating jets 52. It will be noted that the holding bed 50 is mounted on a movable table SO which is slidably movable by the first ram 55 along tracks provided by spaced-apart elongate rods 61. Second rams S3 move the holding bed 50 upwardly into a trimming position illustrated in Fig. 4 in which the edges of the plastic article are adjacent the heating jets 52. When the heating jets 52 have been operated, and the side edges of the article are smoothed the procedure is reversed, the second rams 63 being operated to move the holding bed 50 downwardly onto the support table 60. The first ram 55 is then operated to move the support table 60 and holding bed 50 into an article release and holding position illustrated in Fig. 3.
Many variations of the specific embodiment of the invention described will be readily apparent and accordingly the invention is not limited to the embodiments hereinbefore described which may be varied in detail.
