    Title: Shirt bag place device and method for opening, spreading and placing a shirt bag in a holder
    DESCRIPTION The invention relates to a shirt bag positioning device. The invention also relates to a method for opening, spreading and placing a shirt bag in a holder.
    A shirt tote, or short shirt bag, is a shirt-shaped foil bag with integrally formed handles, as described and shown in US2011 / 0164836 and US 4,676,378. The shirt bags (T-shirt bag or handle bag or vest shaped shopping bag) can be formed with or without side weft or side gusset from tubular foil material. The top edge and bottom edge are sealed, after which a U-shaped part is cut out at the top of the bag. This creates a shirt bag with two handles. When using side wefts, the open handles on the front and back of the shirt bag comprise two layers of foil. The shirt bags are preferably made of a lightweight, flexible and strong thermoplastic material. For manual removal of the shirt bags from a bundle, supports are used with pins that protrude through the handles of the shirt bags. These are described in, among others, US 4,676,378 US 5,938,033 and US 2009/0274396. To this end, the handles are provided with a perforation or opening, so that the shirt bags can be slid onto the pins. To open and spread the shirt bag for use as a shopping bag, for example, the front foil layer of the shirt bag is pulled off the bundle by hand, while the rear foil layer of the shirt bag remains in the same position on the pins. The shirt bag can now be opened and spread spread by its handles and lifted off the pins with two hands, or filled through the opening at the top. In the name of the applicant NL1012033 describes a method and a device for arranging a foil bag in an outer box or crate. The foil bags are provided with side wefts and have a completely open top, because no weld or seal is provided on the top. In NL1012033 the foil bags are opened and spread by the described device and then placed in a holder,
    such as an outer carton or a crate.
    One (or more) foil bag is arranged per outer box or crate, whereby the top edges of the foil bag are folded from the inside to the outside around the side walls of the outer box or crate.
    The foil bags are provided with two perforation openings, with which the bundle of foil bags can be attached and hung on a set of carrying pins.
    In NL1022290 in the name of the applicant a foil bag is disclosed for use in the device according to NL1012033, wherein the foil bag is provided with two perforation openings, whereby cuts are provided at the perforation openings of the front foil layer and of the front side weft parts and wherein no cuts are made. are provided at the perforation openings in the rear foil layer and in the rear side weft parts.
    This allows the foil bag to be opened more easily by the locator, because the front perforation openings can be easily moved over the support pins, while the rear perforation openings are more difficult to move over the support pins because the rear perforation openings are substantially the same diameter as the support pins and the perforation openings pinch slightly on the carrier pins and encounter resistance when moving on the carrier pins.
    Unlike foil bags, shirt bags are provided with a weld or seal on the top so that the shirt bags cannot be placed with folded top edges in a container such as a crate.
    A container is an open square or rectangular container or crate with closed or open side walls, in which various articles can be stored.
    Shirt bags are fitted with their handles in recesses in opposite top sides of the side walls of the container.
    Often two or more shirt bags are arranged in a holder and tightened.
    Parts of the handles extend on the outside of the side walls of the container.
    For opening, spreading and placing a shirt bag in a holder, a positioning device is required, which opens the shirt bag and also opens both handles, and which then places the shirt bag in the holder by arranging the handles in the recesses of the holder. the holder.
    NL1043347 of the applicant describes a shirt bag, which is specially designed for use in a placement device for shirt bags.
    It has been found that the known positioning device for foil bags with perforation openings near the open, unwelded top side cannot be used for opening and placing in a holder shirt bags with perforation openings in handles provided with a top seal.
    It is therefore an object of the present invention to provide a positioning device which can open a shirt bag automatically at high frequency and with high reliability automatically from a bundle of shirt bags on carrier pins; and which can then place and fix the opened shirt bag with high reliability in recesses in the top edge of the side walls of a container.
    Because the dimensions of the shirt bag are determined specifically for a particular container, the shirt bag positioning device according to the invention must also be able to place shirt bags of different sizes and with different numbers in containers of different sizes, with the bottom of the shirt bag. on the bottom of the container and the handles fixed in the recesses in the side walls of the container.
    The shirt bag positioning device must therefore be flexible and easily adaptable to the chosen size of the shirt bag, the desired number of shirt bags in a holder, the dimensions of the holder, and the positions of the recesses in the side walls of the holder. holder.
    The above tasks are fulfilled according to the invention, with a position direction comprising: four handle spreader members, two on the left side for the left carrying opening and two on the right side for the right carrying opening of the shirt bag, a left gripping hook and a right gripping hook, which are configured to support the left handle and the right handle of a shirt bag, respectively; wherein the two gripping hooks are movable towards each other from the outside of the shirt bag from the left side and from the right side in the longitudinal direction of the shirt bag, respectively, from an open position outside the shirt bag to a closed position in the left carrying opening and the right carrying opening respectively of the shirt bag, wherein in the closed position of the gripping hooks the handle spreader members are positioned within the gripping members.
    With two handle spreaders (also known as spreader bars) and a gripping hook for the left handle and two handle spreaders and a gripping hook for the right handle, the handles of a shirt bag can be reliably opened and placed in containers of variable dimensions such as a crate, which are equipped with recesses in the top of the side walls.
    In particular, the gripping hooks are provided with a U-shape, with the open sides of the U-shape facing each other and towards the handle spreader members.
    The U-shape allows the gripping hook to support the carrying openings of the shirt bag handles and the opening of the handles in the width direction of the shirt bag is performed more reliably. The opening and tensioning of the shirt bag on its handles by the handle spreader members can also be performed more reliably.
    Preferably, the gripping hooks comprise two longitudinal walls extending parallel in the longitudinal direction of the shirt pocket, the longitudinal walls sloping towards the shirt pocket.
    With these measures, the gripping hooks with the narrow ends of the longitudinal walls can more easily be inserted into the carrying openings of the handles of the shirt bag and then the carrying openings can be opened further on the wide parts of the longitudinal walls in the height direction of the shirt bag, so that the handle spreader members the handles can grip well and they can be reliably inserted into the carrying openings of the handles.
    In a preferred embodiment, the handle spreaders extend in the height direction of the shirt bag and are movable in the height direction and the longitudinal direction of the shirt bag, the undersides of the handle spreaders being substantially formed as flat plate fingers.
    It has been found that with these measures the handles can easily be tensioned and subsequently arranged in a holder such as a crate.
    Preferably, the handle spreader members and the gripping hooks are arranged to jointly move outwardly in the longitudinal direction of the shirt bag to tighten the handles of the shirt bag. Because the handle spreaders and the gripping hooks move together outwardly and the shirt bag stretch by its handles in a narrow rectangular shape, the shirt bag is prevented from slipping off or falling off the handle spreaders because the handle is clamped between the longitudinal walls of the gripping hooks and the handle spreader members.
    In particular, the four handle spreader members are arranged to change the distance between them in a horizontal plane under a controlled 45 degree movement, so that the first dimension of the shirt bag, for example in the longitudinal direction, is reduced and simultaneously the second dimension of the shirt bag, for example. in the width direction, is increased by the distance of the decrease from the first dimension.
    The same circumferential tension on the handles and the shirt bag is hereby obtained over the entire movement of the handle spreader members and the shirt bag is prevented from shooting off or falling off the handle spreader members.
    The shirt bag has now obtained a final desired staggered size, which is equal to a horizontal plane formed by the recesses in the side walls of the container.
    In a special embodiment, the positioning device is provided with clamping elements, which are adapted to fix the tensioned handles of the shirt bag on the handle spreader members.
    These clamping elements prevent the shirt bag from slipping or becoming detached from the handle spreader members during opening, spreading and placing the shirt bag in a holder.
    The clamping elements also ensure that the shirt bag cannot bulge outwards on the outside of the handle spreader, in order to prevent the handle from being placed completely in the recesses in the top sides of the side walls of the container.
    In particular, each handle spreader is provided with a plunger element, which is adapted to press the handles into the recesses in the side walls of the container.
    Preferably, the plunger element comprises an elongated plate-shaped element which extends and is movable in the height direction of the shirt pocket.
    In an alternative embodiment, each handle spreader includes a handle support member extending parallel to the handle spreader in the height direction of the shirt bag, and wherein the distance between a handle spreader and a handle support member in the longitudinal direction of the shirt bag is greater than the thickness of the shirt. the side wall with the recess of the container, such that the handle support member is positioned along the inside of the side wall with the recess of the container to tension the handles of the shirt bag straight above the recesses in the side walls of the container.
    With handle support members parallel to the handle spreader members, the handles can be pulled taut and positioned precisely, without bulging, above the recesses in the holders.
    In a special embodiment of the plunger element, the plunger element comprises two elongated plate-shaped elements, which extend parallel in the height direction of the shirt bag, and wherein the distance between the two elongated plate-shaped elements in the longitudinal direction of the shirt bag is greater than the thickness of the the side wall with the recess of the container, so that the two elongated plate-shaped elements along the inside and the outside of the side wall with the recess of the container can be moved to press the handle into the recesses of the side walls.
    In particular, each handle spreader is provided with outer elongated plate-like elements and each handle support means is provided with inner elongated plate-like elements.
    In particular, the plate-like elements of the plunger element overlap in the width direction of the shirt bag at least partially with the handle spreader and with the handle support member.
    With the plunger elements, the front parts and the rear parts of the left and right handles positioned in the previous steps can be pressed into the recesses in the top of the side walls of the container by having one or two elongated plate-shaped elements along the inside and / or the outside of the side wall with a recess of the holder can be moved. Because the plunger members partially overlap the associated handle spreader and handle support member and preferably extend between the side walls and the handle spreader members and the handle support members, the plunger members can quickly and reliably press the tensioned handles into the recesses.
    In particular, the carrying pins are provided with a protrusion or a widening at their ends, so that the rear parts of the handles remain clamped on the protrusion without cutting at the perforation opening and the shirt bag and the carrying openings can be opened completely and reliably.
    The invention also relates to a method for opening and spreading a shirt bag (shirt-shaped foil bag with integrally formed handles) for placing it in a container provided with recesses in the top of the side walls, comprising the steps of: providing a bundle of shirt bags on a support member by providing both handles with a continuous suspension opening and for mounting on two support pins; removing the front handle parts of the shirt bag from the carrying pins so that the handles of the shirt bag are opened; inserting a left gripping hook and a right gripping hook into the carrying openings of the shirt bag handles from the outside of the shirt bag from the left side and from the right side in the longitudinal direction of the shirt bag respectively;
    inserting four handle spreaders, two in the left carrying opening and two in the right carrying opening of the shirt bag, the handle spreaders being positioned within the gripping means; move the handle spreaders and gripping hooks together outwardly in the longitudinal direction of the shirt bag to tighten the shirt bag handles. By placing the two left handle spreaders in the left grab hook for the left handle and the two right handle spreaders in the right grab hook for the right handle, and by the handle spreaders and the grab hooks moving together outwardly and the shirt bag by its handles stretching into a narrow rectangular shape, the shirt bag is prevented from slipping or falling off the handle spreader members by the handle being sandwiched between the longitudinal walls of the gripping hooks and the handle spreader members. This allows the handles of a shirt bag to be reliably opened and placed in a container of variable dimensions such as a crate with recesses in the top of the side walls.
    In particular, the method according to the invention further comprises the step of: changing the mutual distance between the four handle spreader members with a controlled 45 degree movement in a horizontal plane, so that the first dimension of the shirt bag, for example in the longitudinal direction, is reduced and simultaneously the second size of the shirt pocket, for example in the width direction, is increased by the distance from the decrease of the first size.
    This makes it possible to provide the shirt bag with the desired staggered dimensions which are equal to the dimensions of a horizontal plane formed by the recesses in the side walls of the container, while at the same time preventing the shirt bag from slipping off or falling off the handle spreader members.
    Preferably, the method further comprises the step of: moving the shirt bag with tensioned handles downwardly in the height direction of the shirt bag to the container, with the flat plate-shaped fingers on the underside of the handle spreading members on the outside of the side walls with the recesses of the container. be positioned.
    In particular, the method further comprises the step:
    placing handles in the recesses in the side walls of the container by means of plunger elements, provided on each handle spreader, by moving the plunger elements downwards in the height direction of the shirt bag.
    By first positioning the front and rear parts of the handles tensioned on the handle spreader members exactly above the recesses of the holder, these parts of the handles can be slid off the handle spreader members easily and reliably with plunger elements and into the recesses in the top of the side walls. the holder.

    Figure 11 shows the final situation with the shirt bag open and with the handles tensioned in the recesses of the holder.
    Embodiment example Figure 1 shows a bundle of shirt bags 1, which are suspended in a shirt bag placing device by means of carrying pins 29. The support pins 29 are provided with a protrusion or widening 32 at the end. In Figure 2, an opened shirt bag 1 is shown in more detail with a front foil layer 2, a rear foil layer 3, a left side weft 4 and a right side weft. 5, each having a front side weft part 6, 8 and a rear side weft part 7, 9. Such shirt bags are made as foil bags from a tubular foil, from which by means of applying bottom / top welds to the bottom edge and the top edge individual foil bags are manufactured. When side wefts are applied, they are also bonded at the bottom edge and top edge to the front and back film layers. Because the foil bag is manufactured from a single piece of tubular foil, the different foil layers of the foil bag will be substantially the same in terms of composition and physical properties, including foil thickness.
    In Figure 2 it is shown that the front foil layer 2 and the rear foil layer 3 and the two side wefts 4, 5 at the bottom edge 10 and the top edge 11 are joined together. At the top of the shirt bag 1, two fishing rods 12, 13 are formed by providing a recess 14, which extends from the top edge 11 into the two side wefts 4, 5, so that a left and a right carrying opening 15 and 16, respectively. is formed, by cutting away the joint between the side wefts 4, 5. The front foil layer 2 with the front side weft parts 6-8 form the front handle parts 12.1 and 13.1; the rear foil layer 3 with the rear side weft parts 7-9 form the rear handle parts 12.2 and 13.2. The two handles 12, 13 are provided with a continuous suspension opening 17, 18 consisting of four perforation openings in the left handle 12 and four perforation openings in the right handle 13, respectively for the front foil layer 2, the front side weft parts 6, 8, the rear side weft parts 7, 9 and the rear foil layer 3. The shirt bag 1 is thus designed and suitable to be hung on a set of carrying pins 29 and to be opened. The opened shirt bag 1 in Figure 2 has a height direction H, a longitudinal direction L and a width direction B.
    The perforation openings in the left handle 12 and the perforation openings in the right handle 13 in the front foil layer 2 and in the front side weft parts 6, 8 are provided with a cut. The cuts preferably extend from the perforation openings so that the front handle portions 12.1 and 13.1 slide easily over the support pins 29 and over the protrusion or widening 32 of the end of the support pins 29. The perforation openings in the rear handle parts 12.2 and 13.2 are not provided with cuts, so that the rear handle parts cannot slide easily over the flare 32 of the end of the carrying pins 29, so that the handles 12, 13 of the shirt bag 1 can be easily opened. Because it is important when opening a shirt bag that the carrying openings 15, 16 are properly opened and are accessible to the opening mechanism of the positioning device, preferably point connections 21, 22 are provided in the front handle parts 12.1 and 13.1 between the front foil layer 2 and the front side weft parts 6, 8. It has been found that by arranging point joints 21, 22 in the handles, the lateral insertion of the gripping hooks of the opening mechanism of the positioning device into the carrying openings 15, 16 of the shirt pocket with high reliability and high frequency can be carried out. In Figures 1 and 2, two vacuum cups or vacuum elements 50 of the opening mechanism of the deployment device are shown. These vacuum elements 50 engage under the through-hanging openings 17, 18 on the front film layer 2 of the left handle 12 and the right handle 13. According to the applicant's easy-open system, the front film layer 2 of the shirt bag remains on the vacuum elements 50 and the rear foil layer 3 on the easy-open carrier pins 29. This position, as shown in Figure 2, is the starting point for the shirt bag placement device according to the invention. The rear handle parts 12.2 and 13.2 still hang on the carrying pins 29, which is preferably provided with a bulge or flared end 32. The front handle parts
    12.1 and 13.1 have already been removed from the carrier pins 29. The front side weft parts 6 and 8 in the front handle parts 12.2 and 13.2 are closely abutting the front foil layer 2, so that large spacious left and right carrying openings 15, 16 are formed for the opening mechanism of the shirt bag setting device.
    In Figure 3 the opening mechanism of the positioning device according to the invention is shown with left gripping hook 51 and right gripping hook 52 and with four spreader brackets or handle spreader members 53.1, 53.2, 53.3, 53.4; left handle spreader members 53.1 and 53.2 for the left carrying opening 15 and right handle spreader members 53.3 and 53.4 for the right carrying opening 16 of shirt bag 1. The four handle spreader members are controlled and moved independently of each other, the mutual movements and positions are usually coupled. Preferably the left handle spreaders 53.1 and 53.2 and the right handle spreaders stand
    53.3 and 53.4 in the width direction B in one line one behind the other, as shown in Figure 3. The handle spreader members in this exemplary embodiment extend substantially vertically in the height direction H of the shirt bag as flat plate-shaped fingers. In particular, the handle spreader members are constructed with double plates or fingers, with a plate on the inside of the side wall of the container and a plate on the outside of the container. The main function here is that the handle is stretched tightly around the handle spreader, so that it can be positioned well above the recess and that the plunger is also able to press the handle properly into the recess. The gripping hooks 51, 52 can be inserted into the carrying openings 15, 16 to support the left and right handles and to facilitate tensioning of the shirt bag. The left grab hook 51 is moved from its open position on the outside of the shirt bag (Figure 3) to a closed position (Figure 4) in the left carrying opening 15. The right grab hook 51 is moved from its open position on the outside of the shirt bag ( Figure 3) is moved to a closed position (Figure 4) in the right carrying opening 15. The gripping hooks 51, 52 are thereby moved towards each other, for example by rotation about a pivot axis (not shown). The four handle spreaders 53.1, 53.2, 53.3, 53.4 are positioned within the opened shirt bag so that the left handle spreaders 53.1 and 53.2 can engage the left handle 12 from the inside and the right handle spreaders 53.3 and 53.4 can engage the right handle 13 from the inside. In Figure 4 the two gripping hooks 51, 52 are shown in the closed position, wherein the handle spreader members 53.1, 53.2, 53.3, 53.4 are positioned within the gripping hooks 51, 52. In this exemplary embodiment the gripping hooks are provided with a U-shape, the open sides of the U-shape face each other and towards the handle dividers. The U-shape of the gripping hooks comprises two parallel longitudinal walls 54, 55, which extend in the longitudinal direction L and the height direction H of the shirt bag, and within which the handle spreader members are positioned. The longitudinal walls 54, 55 may be connected to each other by a right angle connecting element 56, which extends in the width direction B of the shirt bag. The longitudinal walls 54, 55 preferably slope in the longitudinal direction L in the direction of the shirt bag and in the direction of each other, so that the gripping hooks can easily be inserted with the narrow ends of the longitudinal walls in the carrying openings of the handles of the shirt bag. ; and so that subsequently the carrying openings can be further opened on the wide parts of the longitudinal walls in the height direction H of the shirt bag, so that the handle spreaders can properly engage the handles and be reliably inserted into the carrying openings of the handles. The longitudinal walls of the gripping hooks also ensure that the handles are positioned in the correct position in the height direction H of the shirt bag on the handle spreader members. The combination of the gripping hooks and the handle spreader means that the handles are opened and that the shirt bag is tensioned by its handles. The combination ensures that the handle spreaders are displaced through the carrier openings 15, 16 and that the handle spreaders do not contact the lower edges of the carrier opening, as formed by the U-shaped cut-out portion of the front side weft members 6-8 and the rear side weft parts 7-9. In Figure 5 it is shown that the handles 12, 13 of the shirt bag 1 are stretched about the handle spreader members 53.1, 53.2, 53.3, 53.4. The left grab hook 51 containing the left handle spreader members 53.1 and 53.2 and the right grab hook 52 containing the right handle spreader members 53.3 and 53.4 are moved away from each other in the longitudinal direction L of the shirt bag 1. The top of the handles with the welded top edge 11 are now tightly stretched around the handle spreader. The handle spreader extends the shirt bag into a narrow rectangular shape. During this movement, the shirt bag is released from the easy-open (carrying) pins and from the vacuum cups, or vacuum elements 50. In the special embodiment of Figure 5, the handle spreader members 53.1, 53.2, 53.3, 53.4 are each provided with a handle support member 53.5, 53.6, 53.7, 53.8. These handle support members 53.5, 53.6,
    53.7, 53.8 extend substantially parallel in the height direction H of the shirt bag 1 to the handle spreader members 53.1, 53.2, 53.3, 53.4 and are often provided with a corresponding shape. The distance between a handle spreader and a handle support member in the longitudinal direction L of the shirt bag is greater than the thickness of the side wall with the recess 61.1, 61.2, 61.3, 61.4 of the container, so that the handle supports along the inside of the side wall with the recess of the container is positioned to stretch the handles 12, 13 of the shirt bag 1 straight on top of the recesses 61.1, 61.2, 61.3, 61.4 in the side walls of the container 60, and perpendicular to the side walls. In Figure 6, the gripping hooks 51, 52 have been removed from the handle spreader members 53.1,
    53.2, 53.3, 53.4 and therefore also out of the carrying openings 15, 16 of the handles by, for example, tilting the gripping hooks outward about a pivot axis from the closed position to the open position. The handle spreader members 53.1, 53.2, 53.3, 53.4 (and optionally the handle support members 53.5, 53.6, 53.7, 53.8) can now be moved independently of each other in the width direction B and longitudinal direction L with respect to each other. The positioning device is optionally provided with clamping elements 58, which are arranged to fix the tensioned handles 12, 13 of the shirt bag on the handle spreader members 53.1, 53.2, 53.3, 53.4 (and optionally the handle support members
    53.5, 53.6, 53.7, 53.8). The clamping members 58 are provided on the outer sides of the handle spreader members (and the handle support members) in the width direction B of the shirt bag, so that the tensioned handle members in the longitudinal direction L of the shirt bag can be clamped between the handle spreader members (and the handle supports) and the clamp members 58 , to prevent the handle parts from prematurely detaching from the handle spreader members. The clamping elements 58 also ensure that the shirt bag on the outside of the handle spreader (and the handle support) cannot bulge outwards, in order to prevent the handle from being placed completely in the recesses 61.1, 61.2, 61.3, 61.4 in. the tops of the side walls of the container. Figure 7 shows the situation in which the handle spreader members 53.1, 53.2, 53.3,
    53.4 (with optionally the handle support members 53.5, 53.6, 53.7, 53.8) are displaced with respect to each other, preferably with a controlled 45 degree movement, simultaneously in a horizontal plane, defined by the width direction B and the longitudinal direction L of the shirt bag 1. Compared to the situation in Figure 7, the first size of the shirt bag, in the longitudinal direction L of the shirt bag, has been reduced and at the same time the second size of the shirt bag, in the width direction B of the shirt bag, has been increased. To keep handles 12 and 13 stretched on the four handle spreader members (and the four handle supports), the reduction in the first size is substantially equal to the increase in the second size. To this end, the handle spreader members are simultaneously displaced at an angle of 45 degrees with respect to the width direction B and the longitudinal direction L. This maintains the same circumferential tension on the handles and the shirt bag throughout the movement of the handle spreader members. The left handle spreaders 53.1 and 53.2 and the right handle spreaders 53.3 and 53.4 are aligned one behind the other in the width direction B. The lower ends of the plate finger spreaders protrude through the carrying openings of the shirt bag. The shirt bag has now obtained the desired final spread size, which is equal to the positions of the four handle spreaders and to the recesses of the container.
    In Figure 8 it is shown that the tensioned shirt bag 1 is moved downwards in the height direction H of the shirt bag to above the holder 60, to place the shirt bag in the recesses 61.1, 61.2, 61.3, 61.4. In Figure 8 the container is a crate 60, with recesses 61.1, 61.2, 61.3, 61.4 provided in the top sides of the side walls of the crate for receiving and feeding the handles 12 and 13. In Figure 8 it is shown that the handle spreader members 53.1, 53.2, 53.3, 53.4 (without the handle supports 53.5, 53.6, 53.7, 53.8) are positioned over the side walls of the crate such that the outer edges 57.1, 57.2, 57.3, 57.4 of each of the handle spreader 53.1, 53.2, 53.3 , 53.4 approximately above a recess 61.1,
    61.2, 61.3, 61.4 is positioned.
