The present invention, in some embodiments thereof, relates to automated garment loading and, more particularly, but not exclusively, to modifications to a pallet to allow automated mounting of the garment on the pallet for printing or other purposes.
Loading paper for printing is well understood and technologies such as vacuum or rollers are able to grab and load sheets of paper onto high speed printers and other devices that use paper. However textiles and clothing are more difficult.
Textiles for printing often come in the form of ready-formed garments. In such a case the garment is to be fitted around a form-pallet, so that the upper side of the garment is over the pallet and the lower part of the garment is below the pallet. Fitting of the garment onto the form pallet may be manual, or mechanical grippers may be used to assist. For example, the operator may feed the ends of a garment onto mechanical grippers associated with the form pallet. However, garments are not uniform shapes. They include parts such as sleeves, pockets, buttons, trouser legs and collars, so that getting the garment correctly fitted above and below the form pallet is only part of the story.
In addition, dust and lint on the garment may spoil the print quality. The operator is often required to brush the garment prior to placing on the pallet.
Applicant's patent application IL2018/051408 deals with issues of gripping the garment so that the garment may be picked from a pile and pulled over the form pallet automatically. However, the issues of sleeves etc. are not addressed, and the upper and lower parts of the garment may still be caught on edges of the form pallet or other parts of the printing apparatus.
The present embodiments relate to mechanical modifications for the smooth loading of a garment onto a pallet, so that loading may be carried out with ease by an operator or using mechanical grippers as preferred, and to ensure that printing may take place without interference by irregular parts of the garment such as the sleeves, or by dust or lint on the garment. Thus a roller coated with adhesive or a shaver may flatten the upper surface of the garment over the platen surface. Slides may smooth the passage of the upper and lower surfaces of the garment to slide above and below the platen respectively and a sleeve handling mechanism may handle the sleeves to ensure that the sleeves are kept away from the surface being printed.
According to an aspect of some embodiments of the present invention there is provided textile processing apparatus having a self-reconfigurable form pallet for a garment, the pallet having an approach direction from which a garment to be placed on the pallet approaches the pallet, and a travel direction in which the pallet approaches a processing machine for printing or wherein the processing machine approaches the pallet, the garment having an upper surface and a lower surface, the pallet comprising:
In embodiments, the roller coated with adhesive and/or a shaver is retrievably mounted to advance towards and retreat from a plane of the upper garment surface.

Unless otherwise defined, all technical and/or scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the invention pertains. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of embodiments of the invention, exemplary methods and/or materials are described below. In case of conflict, the patent specification, including definitions, will control. In addition, the materials, methods, and examples are illustrative only and are not intended to be necessarily limiting.
Some embodiments of the invention are herein described, by way of example only, with reference to the accompanying drawings. With specific reference now to the drawings in detail, it is stressed that the particulars shown are by way of example and for purposes of illustrative discussion of embodiments of the invention. In this regard, the description taken with the drawings makes apparent to those skilled in the art how embodiments of the invention may be practiced.
In the drawings:
The present invention, in some embodiments thereof, relates to automated garment loading and, more particularly, but not exclusively, to modifications to a system to allow automated mounting of the garment on the pallet for printing or other purposes.
A form pallet provides a feeder to a garment processor, such as a printer or the like, and is adapted for a garment having appendages such as sleeves. The pallet comprises a flat pallet surface, and a sleeve handling mechanism configured to take hold of said appendages as the garment slides onto the pallet. The sleeve-handling mechanism holds the appendages away from the flat pallet surface as the garment upper surface settles on the flat pallet surface, thereby to keep the appendages away from the processing of said garment. Flaps, included with the pallet to hold the garment from the sides and tension the upper surface, close over the appendages which are held in the rotating path of the flaps so that the appendages are kept firmly in position during the processing.
In the present embodiments a sleeve handling mechanism grabs hold of and moves away the sleeves, trouser legs, frills or other garment extensions, herein appendages, from the printing area, and/or at the same time keeping the sleeves etc. from flapping or extending outwards so they do not get caught on parts of the printing apparatus. Rounded or sliding edges added to the pallet and surrounding parts ensure that the upper and lower parts of the garment fit smoothly around the form pallet without getting caught, so that garment placement is smooth and does not need to be corrected or repeated. Furthermore an adhesive covered cylinder rolls over the printing area of the garment as the pallet advances into the printing area, to remove dust, lint etc.
An embodiment may comprise a reconfigurable form pallet provides a manual or automated feeder to a garment processor, such as a printer or the like, and is adapted for a garment having appendages such as sleeves. The pallet comprises an interchangeable flat pallet surface; a appendages and sleeves handling mechanism configured to take hold of said appendages as the garment slides onto the pallet; a moving roller with adhesive or shaver to collect dust, fibers, and such from the garment; rounded surfaces for smooth movement of the garment; flaps on both sides for attaching the garment to the pallet without wrinkles or deviations from the center;
Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not necessarily limited in its application to the details of construction and the arrangement of the components and/or methods set forth in the following description and/or illustrated in the drawings and/or the Examples. The invention is capable of other embodiments or of being practiced or carried out in various ways.
Referring now to the drawings,
The pallet has an approach direction—arrow 14—from which a garment to be placed on the pallet 12 approaches the pallet. The pallet then travels in the same direction into the printing machine for printing. The garment has an upper surface that slides over the form pallet and a lower surface that slides under the pallet. The upper surface of the garment is thus located over flat pallet surface 16 and provides a flat surface of the garment for printing. As the pallet takes up position on the pallet, flaps 13 close to pull down on the sides of the garment and pull the upper surface of the garment into tension.
A roller coated with adhesive 18, shown more fully in
The roller coated with adhesive is mounted on mountings 20 which are retrievable so that the roller may be advanced towards and retrieved from the plane of the upper garment surface. The mountings 20 may be flexible, so as to accommodate local changes in thickness of the garment upper surface. Thus for example the garment may have pockets or buttons or other parts that increase or decrease the thickness, and the resilience of the mountings allows the roller to manage such changes in thickness.
Thus, the roller coated with adhesive may be axially mounted, to rotate around its central axis.
Returning now to
It is noted that although
The garment may be slid over the pallet by an operator, or the base of the garment may be fixed into mechanical grippers which then retract across the pallet to pull the garment over the pallet. The grippers may pull the upper side of the garment clear of the top of the pallet. The arms 22 form a sleeve handling mechanism and guide the appendages inwardly as the garment slides onto the pallet. Accordingly the appendages are guided to the sides of the pallet, away from the flat upper pallet surface 16 as the garment upper surface settles on the flat pallet surface where they can be securely held by the flaps as discussed above.
It is to be noted that many garments do not have appendages, but may still need to be loaded smoothly onto a form pallet.
