Definitions

  • the invention relates to a manipulating device that has been especially designed to pick up tinplate sheets from a receiving table and place them either upon a turning device or upon a collecting tray, in order to prevent the treated surface from being damaged in any way during the handling process.
  • the object of the invention is not only to prevent the tinplate sheets from being damaged, as mentioned above, but also to ensure that the transferral between the reception zone and the zone where they are deposited is carried out in a fully automated way.
  • the invention can be applied not only in the process of manufacturing packaging for food products using tinplate sheets, but also, for example, for packaging for canned preserves, foodstuffs and similar.
  • Metallic cans made from tinplate sheets are used to manufacture packaging that is used for certain types of food products or similar, and once these sheets have been duly punched out, formed and attached to each other, they form a sealed and airtight container. This treatment of the inner surface of the packaging is originally carried out on the tinplate sheets prior to the punching out process and manufacturing the packaging.
  • the other solution which is mechanical, uses machines that operate in a linear way, in such a way that a conveyor belt moves the sheets that have been cut by the cutting machine, from the latter to a lift that raises them so that a mechanical manipulator arm can collect them and send them to a tray that supplies the machine that manufactures the packaging.
  • the problem is that said machine is invariably in a linear plane with the conveyor belt; furthermore, in the event of a decision being taken to store those sheets, the transport process to the pallets or the storage zone has to be carried out manually.
  • the entire handling process takes place with the treated surface of the sheets facing upwards, which is how the machine that manufactures the packaging has to receive them, which amounts to a permanent risk of the treated surface being scratched, thereby rendering it useless for being turned into a packaging, in such a way that if one wishes to overcome this problem, the cutting machine must supply the sheets with a treated surface that faces downwards, which means that it is necessary to turn it over manually immediately before it reaches the machine that manufactures the packaging.
  • the manipulating device that is the object of the invention has been devised to overcome the aforementioned problem in a completely satisfactory way, thus permitting the entire process to be carried out in a fully automated way, not only when the tinplate sheets are arranged on a pallet or on a storage tray, but also when they are arranged on a supply tower on the machine that makes the packaging, making it possible for the entire sheet manipulation process to be carried out with the treated surface facing downwards, because the sheet is automatically turned over immediately before it is supplied to the above-mentioned machine.
  • the manipulating device that the invention proposes be provided with a receiving table, upon which the sheets that are supplied are placed by the cutting machine with the treated surface facing downwards, this receiving table being equipped with several channels whose number and width can be adjusted, so that they can receive the different types or sizes of sheet, with a loading zone where those sheets are placed as they are cut by the cutting machine, either directly by that machine and with the help of a worker, controlling the amount of sheet that is laid on each channel with the aid of a piling height detector, which controls a lift that raises the pile, which is moved to the opposite side of the receiving table, where the pile is then lowered so it can be placed on a support, these supports correspond to different channels on the receiving table, alternately adopting different heights, so that the blocks or packs of sheets are also arranged in a staggered formation, which makes it easier for them to be gripped for the next manipulation.
  • a manipulator arm moves the sheets from the receiving table either to the unloading zone of the machine that makes the packaging, or to a collection tray or pallet.
  • This manipulator arm is equipped with a claw with pincers and wheels lined with rubber, adaptable pincers whose width can be adjusted to cope with different sheet formats, the pincers being aided by adjustable clamping devices that sandwich the tinplate sheets as soon as the pincers have closed, by means of a pneumatic cylinder, and the above-mentioned manipulator arm can be moved in the direction of the axes of a system of rectangular coordinates, while also being able to rotate at the same time.
  • the unloading zone is equipped with a turning device, composed of a claw that is very similar to the one on the manipulator arm, but in this case it is mounted between two points on an axis that enables a rotation actuator to carry out the turning over action.
  • the claw has been designed in such a way that it carries out a raising movement beforehand, so that it can find a zone that is free of obstruction and perform the turning over action, before descending towards the desired unloading position.
  • the manipulating device is equipped with a collection tray, which enables it to store blocks of tinplate sheets with different lithoprinting, with as many possibilities as there are channels on the receiving table, this collection tray being assisted by a pneumatic cylinder that enable the tinplate sheets to be moved outside, so they can eventually be removed by a person.
  • Figures 1 and 2 show the receiving table, where there is a loading zone (1) and an unloading zone (2), set side by side.
  • a series of channels (3), (3') and (3") are arranged on the loading zone (1), their purpose being to receive piles of tinplate sheets, each channel being formed by a pair of parallel strips, the distance between these strips being adjustable, so that they can adapt to the different sheet sizes.
  • the number of sheets that are positioned on each channel (3) is controlled by a pile detector (4), in such a way that when the maximum number is reached, the channels (3) are raised by means of a pneumatic cylinder (5), and another pneumatic cylinder (6) moves the tinplate sheets to the zone (2), where they are placed on a series of supports (7), (7'), (7"), etc., the number of these being the same as the number of channels (3) that are established in the loading zone (1) and their positions coinciding, but with the peculiarity that these supports (7) are at different heights, as can be seen perfectly in Figure 2 , forming a staggered arrangement for the different piles of tinplate sheets lying on them, which makes it easy for the manipulator arm shown in Figure 3 to grip these blocks of sheets.
  • the aforementioned manipulator arm (8) suspended from the structure (9) of the manipulating device on a position that is considerably raised with respect to the receiving table (1 - 2), is a kind of claw equipped with pincers (10), completed with a pair of wheels (11) lined with rubber so that they do not damage the tinplate sheets during the manipulation process, the width of the pincers (10) being adjustable by means of a guiding and interlocking system so they can be adapted to the different tinplate sheet formats.
  • Adjustable clamping devices (12) work in conjunction with the pincers (10) and, as has already been pointed out, these sandwich the tinplate sheets as soon as the pincers (10) have closed, by means of a pneumatic cylinder.
  • this manipulator arm (8) can be moved vertically, transversally and lengthways, that is to say in accordance with the three axes of a system of rectangular coordinates, so that they can reach any point of the receiving table (1 - 2), and the aforementioned manipulator arm (8) is also able to revolve around itself so that the pincers can face any direction.
  • Figure 4 shows the unloading/turning device, whose structure is similar to that of the manipulator arm (8), that is to say, equipped with pincers (14) completed with a pair of wheels (15), so that it can gently secure the tinplate sheets, these pincers also being operated by a pneumatic cylinder and able to move around the three axes of a system of rectangular coordinates, with the further particularity in this case that the body base (16) of the turning over device is mounted on a transversal axis (17), which enables it to turn over so that it can change the orientation of the treated surface of the sheet, as previously mentioned.
  • Figure 5 shows the collection tray (18) where the different blocks or piles of tinplate sheets with different lithoprinting are to be stored, so that each one of them can subsequently be used when necessary.
  • the manipulating device that the invention proposes has a series of advantages that basically focus on the following aspects:
