Definitions
- the invention relates to the supply of products from an intermediate store to pick-and-place robots according to FIG.
- pick-and-place robots known per se, are used in the confectionery sector and in the frozen food sector. The mostly small and unpackaged foods are made from the
- biscuits straight from the oven, chocolates or frozen mini pizzas, etc. i.e. smaller products lying flat on the main belt that are fed in in large pieces.
- the products can lie in rows or irregularly (chaotically) on the main belt.
- these products are fed to the packaging system via a buffer store.
- These buffers are, for example, multi-layered
- Lifting device or fed with product formations via a vertically swiveling main belt.
- Product formations are typically formed from the continuously arriving product flow using a so-called double pullnose tape known from the prior art.
- a movable belt deflection become dynamic
- Tape length of the tape located in the lift can be filled in one cycle.
- the time resulting from the amount of product must be sufficient for the lift to perform its cycle of up and down strokes, filling and emptying of the lift belt.
- the lift fills the stacked buffer belts at the entrance to the belt storage system according to the first in - first out principle.
- the belt accumulator is primarily used to increase the efficiency of the entire packaging line, because when the downstream packaging device stops, the
- the buffer capacity corresponds to
- the buffer can also be used to cool the products, and the oven can also be emptied if the packaging device is stopped for a long time.
- the required cooling time and the length of the furnace must be used for the
- the total length of the buffer must also be included.
- the product formations are conveyed to one or more of the so-called known.
- Pick-and-place robots are fed in, which contain pick-and-place robots arranged in series over a main belt and the ones fed on the main belt in a multi-axis movement
- the switched pick-and-place robot depends primarily on the piece output supplied. In addition, the consistency and size of the products play an important role
- the picker cells consist of two parallel picker tracks, each with a lower one narrow main belt and multi-axis pick-and-place robots arranged in a row above it. After the storage, the product formations are distributed and fed to a corresponding number of picker tracks depending on the output. The width of the formations is equal to the width of the picker tracks
- the speed of the two main belts under the pick-and-place robot robots can be controlled independently of one another.
- the speed can vary, since it depends on the availability of the assigned pick-and-place robots.
- Two-lane pick-and-place robot cells have the advantage that they can do without additional stand-by robots, because both lanes are independent of one another and do not negatively affect one another. For these reasons, two-lane picker cells can handle the performance with a significantly lower number of pick-and-place robots and also generate even less product loss.
- Feeds to pick-and-place robots according to the prior art are expensive and inaccessible.
- the invention is based on the object of simplifying the feed to the picker cells and thus of building it in a more cost-effective and space-saving manner.
- Fig. 2 is a detailed view of a lift system on the outlet side of the intermediate storage
- the system shown in Fig. 1 consists of a feed belt 1 on which the products arrive from the production, an inlet-side lifting device 2 with which the products are brought to the individual buffer belts 3 of a buffer 4, an outlet-side lifting device 5 with which the Products from the buffer to a
- the feed belt 1 consists in a known manner of a number of belt modules, one of which is a so-called.
- Feed belts of this type are known in the art.
- the inlet-side lifting device 2 with which the
- Buffer 4 are brought, corresponds, like the buffer itself, the known from the prior art devices of this type. Instead of with a
- the belts of the intermediate storage can also be equipped with vertically pivotable belts.
- the outlet-side lifting device 5 hereinafter the
- a lift is in a manner known per se with conveyor belts (lift belts) 13,
- the number and arrangement of the lift belts is determined according to the number and performance of the downstream picker tracks.
- the lift belts 13 are arranged on a height-adjustable platform 14 of the lifting device.
- a turntable 15 is integrated into this platform, by means of which the lift belts can be rotated as a whole around the vertical axis of the lifting device, as indicated by arrow 16 in FIGS. 3 and following
- the lift belts are designed to be horizontally displaceable on the turntable by means of telescopic rails 17.
- the lift belts can thus be raised and lowered, rotated and moved horizontally.
- the elevated buffer belts can be approached precisely by placing the lift belts using the telescopic rails under the flat-shaped outlet-side belt noses of the respective
- Buffer belts can be positioned.
- 3 shows the situation in which the platform assumes a position in which the belts 13 have been moved under the belt nose of the lowermost buffer belt and are filled with products.
- Fig. 4 shows the situation in which the platform is in its lowest position, in which the products on the Feed device to be transferred to the pick-and-place device.
- the direction of travel of the lift belts is transverse to the main conveying direction of the buffer belts.
- the product information is used by the
- the lift straps are in
- the direction of travel of the buffer belts is slightly higher
- Shifted speed than the respective buffer belt is conveying, so that the products are positioned on the lift belts with a defined greater distance from one another.
- the product formations are therefore already at the transition from
- Buffer belt spread out on the lift belts are stopped. After the
- the lift belts are centered on the lift.
- the lift belts are now moved vertically downwards with the lift. During this, the lift belts rotate by a maximum of 90 ° and can then, if necessary, directly inline with the lower loading level
- Pre-dusting tapes and gap closing tapes are supplied to the subsequent pick-and-place robots
- the required angle of rotation can be freely selected between 0 ° and 90 ° and depends on the position of the pick-and-place device.
- the pick-and-place device 7 is centrally below the
- the lift straps must be turned by 90 °. This also applies if the pick-and-place device is centered on the belt buffer, i.e. in the conveying direction of the
- Buffer belts downstream or if a second pick-and-place Place device which is located under the buffer store centrally opposite.
- FIGS. 5-7 arrangements are shown in which one or more pick-and-place devices are not centered on the belt buffer or the lifting device.
- a product transfer unit is used in these systems.
- the necessary number of conveyor belts 18 are mechanically accommodated on one or two levels on a slide 19, and designed to be horizontally displaceable by means of a guide unit 20 driven by an electric motor.
- These conveyor belts 18 are connected directly downstream of the lift belts and can pick up the amount of product formations 1: 1 from the lift belts.
- the product information can be sent directly to the individual pick-and-place robot cells
- FIG. 5a shows a side view
- FIG. 5b shows a plan view of a system in which the pick-and-place devices are arranged next to the intermediate store.
- the lifting device is stacked with two
- FIG. 6a shows a side view and FIG. 6b shows one
- the lifting device has
- FIG. 7 shows a plan view of a system with three pick-and-place devices arranged in parallel next to the intermediate store.
- the allocation to the individual pick-and-place robot lanes is carried out by the clearance notification of the upstream damming and gap closing straps. This means that all pick-and-place Robot lanes continuously supplied with product in line with performance. Overfeeding is excluded, as is an undersupply of product.
- the lift belts do not have to be rotated before the pick-and-place device can be loaded with product.
- the lift belts must be rotated through an angle corresponding to the offset before the pick-and-place device can be loaded with product.
- FIGS. 1-3 Whether the arrangement shown in FIGS. 1-3 or the arrangements shown in the other figures are used depends on the respective space conditions and performance requirements of the production and packaging system.
- Intermediate storage can be charged with product formations without having to rely on curved belts and spreading belts.
- the pick-and-place devices can be placed in almost any position in the run-out area of the belt storage system
- Product transfer unit can be charged with product.
- a further advantage of the solution according to the invention is that the pick-and-place devices to be loaded and a downstream packaging system can be located on an upper or lower level or floor, there too Pick-and-place devices arranged there can also be easily operated with product formations via the lifting device.
