Description

Technical Field

[0001] This invention relates to the technical field of automatic and semi-automatic devices for conveying products for packaging, such as case packers designed to insert products, or blister packs, inner boxes, or case packers designed to insert one or more products into a cardboard box or for storage.

[0002] In particular, the present invention relates to a pusher device for pushing and delivering products.

[0003] For example, the pushing device of the present invention can be used to push and convey products inside a relevant carton, or to push or convey products inside a relevant box, or, for example, to push and convey products from a first conveyor to a warehouse.

[0004] In essence, the pushing device of the present invention can be used in all those situations where it is necessary to apply a push to the product by means of a pushing element (pusher) to perform translation or transfer of the product.

[0005] Typically, in the applications described above, products that need to be pushed and conveyed, such as for insertion into cartons or boxes, require an upper accessory element (often called a reverse pusher, usually composed of layered elements) to facilitate insertion.

[0006] In other cases, the product must be slightly compacted, for example, because it consists of small bags or other types of deformable products, before being inserted into the corresponding cartons or boxes. In these cases, it is necessary to use an upper attachment element that is lowered onto the product and accompanies the product during the process of conveying it through the pusher element.

[0007] Similarly, when products to be transported are stacked together, it is necessary to use upper auxiliary components to prevent the stacked products from being unassembled or scattered during transport.

[0008] In addition, in some packaging cases, in addition to the product, a corresponding information brochure must also be inserted inside the same carton or box.

[0009] In these cases, especially when the product has low rigidity or is deformable, such as in blister packaging, it is necessary to resort to the use of an upper accessory element. This upper accessory element must be pre-driven relative to the product's push element, positioned above the product, and abuts against and pushes the information booklet into the carton to prevent the product pushed by the push element from hitting the booklet and potentially bending or deforming it, thus complicating its insertion into the carton.

[0010] In essence, in the various cases described above, where the push element is used to push and convey products or multiple products in a stack, an upper auxiliary element is required, which must descend onto the product or product stack and move slightly ahead of the push element, for example. Background Technology

[0011] Typically, in order to push and convey products in the various situations described above, the prior art resorts to using a closed-loop conveyor, which is arranged on the side of the conveyor of the products to be pushed and conveyed and parallel to the conveyor.

[0012] Closed-loop conveyors are configured to move push elements in a direction parallel to the product conveyor to position them toward the product, or in directions laterally and vertically to the product conveyor to push and deliver them to their final location (e.g., in a carton or on another conveyor).

[0013] In this respect, the pushing element is carried by a carriage, which is slidably mounted on a sliding guide rail, which is constrained by a closed-loop conveyor and moves in a direction parallel to the product conveyor.

[0014] The bracket is constrained to a cam guide rail adapted such that, during the movement of the sliding guide rail through the closed-loop conveyor, the bracket moves laterally and perpendicularly to the product conveyor, in such a way as to abut and push the product, for example, to transfer it onto another conveyor, such as pushing it into a carton or a box conveyed by a corresponding conveyor located on the side of the product conveyor.

[0015] This type of device has a complex structure, requires a large number of mechanical parts, cannot adapt to changes in the final size of the products to be pushed and conveyed, and cannot guarantee high conveying speeds.

[0016] Document EP 3.157.819, in the name of the applicant, describes an apparatus for introducing blister packaging and corresponding information brochures inside a carton.

[0017] Blister packaging and cartons (with blister packaging inserted) are conveyed by corresponding conveyors arranged in parallel to each other.

[0018] The information brochure conveyor is positioned between the carton conveyor and the blister pack conveyor.

[0019] The device described in the aforementioned document is arranged on the side of the conveyor for blister packaging.

[0020] The device includes a first closed-loop conveyor and a second closed-loop conveyor.

[0021] The first closed-loop conveyor is designed for the first pushing element to move in a direction parallel to the conveyors for blister packaging and cartons.

[0022] The first pushing element is mounted on the first bracket, which is slidably mounted on the first straight guide rail (strip), which is moved by the first closed-loop conveyor in a direction parallel to the conveyor for blister packaging and cartons.

[0023] The first carriage is constrained to a first cam guide rail, which is adapted such that during the movement of the first straight guide rail by the first closed-loop conveyor, the first carriage can move toward the conveyor of blister packaging and cartons, and then away from the conveyor of blister packaging and cartons.

[0024] In this way, the first pushing element can move in the forward direction of the blister pack and the carton, while moving toward and away from the conveyor and carton in the lateral direction of the forward direction, so as to push and convey the blister pack into the carton, and then remove it from the carton once the blister pack has been inserted.

[0025] The second closed-loop conveyor is designed to move the second push element in a direction parallel to the conveyor for cartons and brochures, and is positioned above the first closed-loop conveyor.

[0026] The second pusher element is mounted on the second bracket, which is slidably mounted on the second straight guide rail (bar) that moves by the second closed-loop conveyor in a direction parallel to the conveyor of the cartons and brochures.

[0027] The second bracket is constrained to a second cam guide, which is adapted such that during the movement of the second straight guide by the second closed-loop conveyor, the second bracket can move toward and then away from the conveyor of cartons and brochures.

[0028] In this way, the second pushing element can move in the forward direction of the carton and the brochure, while in the lateral direction of the forward direction, moving toward and away from the conveyor of the carton and the brochure, in order to adjacent to, push and transmit the brochure into the carton, and then remove it from the carton.

[0029] The device described in the document is configured such that the second pushing element is lowered toward the blister pack, and the information booklet is pushed into the carton ahead of the moment when the first pushing element adjacent to and pushes the blister pack into the carton.

[0030] While this type of device has proven effective and functional in inserting brochures and blister packs into individual boxes, it is somewhat complex, not very flexible and adaptable to changes in size, as it requires replacing and adjusting many parts, and cannot achieve very high insertion speeds. Summary of the Invention

[0031] Therefore, the object of the present invention is to provide a novel push device for pushing and delivering products, which can eliminate the above-mentioned disadvantages of the prior art.

[0032] In particular, the purpose of this invention is to describe a pushing device that has a simple structure, is easy to adapt to size changes, and can ensure a high product conveying speed.

[0033] The purpose of the reference is achieved through the push device of the contents of the claim. Attached Figure Description

[0040] Referring to the accompanying table, reference numeral (100) indicates a pushing device for pushing and conveying products, which is the whole object of the present invention.

[0041] The pushing device (100) includes a pushing element (A) adapted to abut against the side of a product (P) or product group (P) (e.g., a product stack), which is arranged on a conveyor (C) and will be pushed and conveyed along a conveying direction (Z) transverse to the conveyor (C).

[0042] The pushing device (100) also includes a reverse pushing element (B) (e.g., a layered element) adapted and sized to be positioned above and facing the product (P) or product group (P), which is arranged on the conveyor (C) and is to be pushed and conveyed by means of the pushing element (A) in a conveying direction (Z) transverse to the conveyor (C).

[0043] Products (P) or product groups (P) to be pushed are typically fed in by a conveyor (C) and must be conveyed in the following ways: transverse to the conveyor (C), for example on a second conveyor (C2) arranged to the side of the conveyor (C); or inside a container (V) (e.g., a carton or box), fed in by a second conveyor (C2) arranged to the side of the conveyor (C); or also at a storage station arranged to the side of the conveyor.

[0044] In essence, in other words, the pushing device (100) of the present invention can be applied to any situation where there is a request to push and convey the product or product group laterally (e.g., via a conveyor) relative to the location of the product or product group, or to push laterally relative to the feeding direction along which the product or product group moves forward via the conveyor.

[0045] To achieve this function, the push device (100) of the present invention is characterized by including a linear drive unit (U) for moving the push element (A) and the reverse push element (B).

[0046] The linear drive unit (U) includes (for example, see...) Figure 1 and Figure 2 ):

[0047] Frame (T);

[0048] A straight guide rail (R) is mounted on the frame (T);

[0049] The stator (S) is arranged in the frame (T) and configured to generate a variable magnetic field along the straight guide rail (R). (In the figure, the stator is symbolically represented by the relative arrows indicating and reference (S), because the stator is pre-set and placed inside the frame (T) and is therefore not visible from the outside, and may be composed of a series of coils that can be powered by current.)

[0050] The first bracket (1) is slidably mounted (e.g. by a corresponding pulley not visible in the figure) on the straight guide rail (R) and includes a permanent magnet (11);

[0051] The second bracket (2) is slidably mounted (e.g. by a corresponding pulley not visible in the figure) on the straight guide rail (R) and includes a permanent magnet (21);

[0052] The third bracket (3) is slidably mounted (e.g., by means of a corresponding pulley not visible in the figure) on the straight guide rail (R) and includes a permanent magnet (31).

[0053] Linear drive unit (U), for example Figures 3 to 12 As shown, the guide rail (R) is positioned laterally to the conveyor (C), which feeds or moves products (P) or product groups (P) to a given position along the feed direction, such that the straight guide rail (R) is arranged laterally to the conveyor (C).

[0054] In detail, the linear drive unit (U) is configured such that the stator (S) is actuable to generate a variable magnetic field along the straight guide rail (R) to interact with the permanent magnet (11) of the first bracket (1), the permanent magnet (21) of the second bracket (2), and the permanent magnet (31) of the third bracket (3), and to allow the first bracket (1), the second bracket (2), and the third bracket (3) to move independently of each other along the straight guide rail (R) toward or away from the conveyor (C).

[0055] The pushing device (100) further includes:

[0056] A first support member (10) is used to support the push element (A), and the first support member is mounted on the first bracket (1) in a manner parallel to the straight guide rail (R);

[0057] A second support member (20) is used to support the reverse pushing element (B); and

[0058] The articulation system (5) is used to support the second support member (20) and to move the second support member (20) relative to the first support member (10), thereby moving the reverse push element (B) relative to the push element (A).

[0059] The articulation system (5) is pre-set and configured as follows:

[0060] The second support member (20) is held parallel to the first support member (10) and above the first support member (10);

[0061] So that it can be driven by moving the second bracket (2) and the third bracket (3).

[0062] More specifically, the articulation system (5) is further configured such that:

[0063] When the second bracket (2) and the third bracket (3) are in a position close to each other (P1) (see, for example, see...) Figure 3 , Figure 7 and Figure 12 The articulation system (5) holds the second support member (20) and thus the reverse push element (B) in an elevated position (PS) above the conveyor (C), and is reciprocatedly positioned at a position (PD) where the second bracket (2) and the third bracket (3) are far apart from each other when the second bracket (2) and the third bracket (3) reciprocate along the straight guide rail (R) by means of the magnetic field generated by the stator (S) (see Figure 4 and Figure 8 The articulation system (5) moves the second support member (20) so that the reverse push element (B) moves toward the conveyor (C) into a lowered position (PA), such that the reverse push element (B) is positioned above and facing the product (P) or the product group (P), which is positioned on the conveyor (C).

[0064] In order to push and convey the product (P) or product group (P) arranged on the conveyor in the transverse conveying direction (Z) to the conveyor (C), the pushing device (100) of the present invention is configured such that, starting from the configuration of the first bracket (1) in the retracted position (PR) relative to the conveyor (C), the pushing element (A) is arranged on the side of the conveyor, and the second bracket (2) and the third bracket (3) are positioned close to each other (P1), such that the reverse pushing element (B) is positioned in the raised position (PS) above the conveyor (C). Figure 3 , Figure 7 , Figure 12 In the scenario shown, the stator (S) can be activated to generate a variable magnetic field along the straight guide rail (R), such that:

[0065] First, the second bracket (2) and the third bracket (3) reciprocate along the straight guide rail (R) by means of the magnetic field generated by the stator (S) to position (PD), at which position (PD), the second bracket (2) and the third bracket (3) are moved apart and spaced a certain distance from each other (see Figure 4 and Figure 8 The articulation system (5) moves the second support member (20) and thus the reverse push element (B) from the rising position (PS) to the falling position (PA) so that the reverse push element (B) is positioned above and facing the product (P) or the product group (P) which is positioned on the conveyor (C).

[0066] Then the first bracket (1), the second bracket (2), and the third bracket (3) move along the straight guide rail (R) by means of the magnetic field generated by the stator (S) to move simultaneously toward the conveyor (C) to convey the first support member (10) and the second support member (20) transversely to the conveyor (C), such that the pushing element (A) abuts against the product (P) or the product group (P) arranged on the conveyor (C) and pushes and conveys the product (P) or the product group (P) transversely to the conveyor (C) in the conveying direction (Z), wherein at least during the first part of the conveying of the product (P) or the product group (P) (see, for example) Figure 3 , Figure 4 and Figure 5 The sequence shown, or Figure 8 and Figure 9 (as shown in the sequence), the reverse push element (B) is maintained above the product (P) or the product group (P) and facing the product (P) or the product group (P).

[0067] At this point, the first bracket (1), the second bracket (2) and the third bracket (3) move along the straight guide rail (R) toward the conveyor (C) and toward the conveyor in a direction close to the conveyor so as to maintain the same reciprocating distance between them.

[0068] Therefore, the pushing device of the present invention can push and transport products or product groups in the translation direction by means of the simple linear movement of the three brackets along the straight guide rail, while keeping the reverse pushing element above the product or product group and facing the product or product group.

[0069] Therefore, the pushing device of the present invention has a much simpler structure than the known types of devices described above, because the pushing element and the reverse pushing element can be moved by the linear motion of three brackets along a straight guide rail, and no mechanical gears or motors are required for the movement, as it is obtained by a magnetic field generated by the stator, which interacts with permanent magnets mounted on the brackets.

[0070] Furthermore, due to this mode of movement, the pushing device of the present invention can achieve a conveying speed of products or product groups that is higher and greater than that achievable by known types of pushing devices.

[0071] Furthermore, if the product or product group to be conveyed is not stopped and placed in a given position by the conveyor (C), but is instead moved forward by the conveyor (C) in a continuous mode, the frame (T) of the pushing device (100) can be pre-installed on the corresponding conveyor, for example in a closed loop, and driven synchronously with the conveyor (C), such that the straight guide rail remains opposite and laterally to the product or product group, so as to allow the pushing element and the reverse pushing element to perform conveying by moving along the straight guide rail via the bracket in the aforementioned manner.

[0072] The following describes additional and other advantageous aspects and details of the pushing device of the present invention.

[0073] In a particularly advantageous aspect, the pushing device (100) is configured such that, after the first portion of the product (P) or product group (P) has been transferred, the stator (S) can be activated to generate a variable magnetic field along the straight guide rail (R), in a manner as shown in (see, for example) Figure 6 ):

[0074] As the first carriage (1) continues to move toward the conveyor (C) to continue pushing and conveying the product (P) or the product group (P) toward the final conveying position (PF) in a conveying direction (Z) transverse to the conveyor (C) (e.g., arranged at the second conveyor (C2), or inside a container (V) on the second conveyor, or arranged on a storage plane), the second carriage (2) and the third carriage (3) may simultaneously move away from the conveyor (C) to retract the reverse pushing element (B) relative to the product (P) or the product group (P).

[0075] Once the product or product group has been transferred to its final position, the first carriage (1) can move along the straight guide rail (R) in a direction of movement away from the conveyor (C) to return to the initial retracted position (PR) so that the pusher element (A) can be returned to the position on the side of the conveyor. Figure 3 Meanwhile, the second bracket (2) and the third bracket (3) can also move away from the conveyor (C) and return to their approach position (P1), so that the reverse push element (B) can also return to the rising position (PS) through the corresponding movement of the articulation system (5).

[0076] In cases where the product or product group must be transferred inside a container (V) (e.g.) Figures 7 to 11 As shown in the figure, it is particularly advantageous for the reverse push element (B) to retract relative to the push element (A) which is still in the conveying step in order to convey the product or product group.

[0077] In this configuration, the pushing device (100) is configured such that after the first portion of the product (P) or product group (P) has been conveyed, the stator (S) can be activated to generate a variable magnetic field along the straight guide rail (R), such that: as the first carriage (1) continues to move toward the conveyor (C) to continue laterally pushing and conveying the product (P) or product group (P) beyond the conveyor (C) to insert the product (P) or product group (P) into a container (V) arranged on one side of the conveyor (C), the second carriage (2) and the third carriage (3) can simultaneously move away from the conveyor (C) to retract the reverse pushing element (B) relative to the product (P) or product group (P), and thus enable the pushing element (A) to push and convey the product (P) or product group (P) completely within the container (V).

[0078] In this way, the reverse push element can accompany the product or product group pushed by the push element, at least until immediately before it begins to be inserted into the container (V).

[0079] Based on the strokes of the second and third brackets, the reverse push element can also be partially inserted into the container to allow products or groups of products to be placed into the container together.

[0080] This is useful when product groups are stacked on top of each other.

[0081] Another advantageous aspect of the pushing device (100) of the present invention is that the articulation system (5) is further configured such that, when the second bracket (2) and the third bracket (3) reciprocate to space each other apart, the articulation system (5) moves the second support member (20), and thus the reverse pushing element (B), toward the conveyor (C) to a lowering position (PA), such that the reverse pushing element (B) is arranged above and facing the product (P) or the product group (P), which is arranged on the conveyor (C), wherein the corresponding end (B1) is arranged in the forward position, beyond the second side of the product (P) or the product group (P), the second side being opposite to the side on which the pushing element (A) will act (see, for example, see...). Figure 4 , Figure 8 and Figure 9 ).

[0082] This particularity is especially advantageous when it is necessary to transfer products with low rigidity or deformability (such as blister packaging) into the inside of a carton and insert corresponding information brochures.

[0083] For example, such as Figures 7 to 12 As shown, the product (P) (e.g., a blister pack or multiple blister packs stacked together) is fed along the conveyor (C) and must be transferred to a carton (V) arranged on a second conveyor (C2) located on the side of the conveyor (C).

[0084] The brochure to be inserted into the carton (C) along with the product (P) is fed in by a corresponding conveyor arranged between the product conveyor and the carton conveyor (details of the brochure and related conveyors are not shown in the diagram). Figure 7 , Figure 8 and Figure 12 In the middle, the brochure (F) is only indicated schematically and generally by dashed lines.

[0085] When brought to the relative descending position (PA), above and facing the product (P), the reverse push element (B) has a relative end (B1) arranged in the forward position, thus protruding beyond the product (P). This fact causes the reverse push element (B) to abut against the brochure and begin its folding step to insert into the carton where no product is present, pushed and struck by the push element against the actual brochure.

[0086] Another particularly advantageous aspect of the pushing device of the present invention is that it is configured such that, starting from a configuration in which the second bracket (2) and the third bracket (3) are placed close to each other (P1), the stator (S) can be activated to generate a variable magnetic field, such that the second bracket (2) and the third bracket (3) can reciprocate to move away from each other at different distances, and the articulation system (5) is configured such that, when the second bracket (2) and the third bracket (3) reciprocate to move away from each other at different distances, the second support element (20), and thus the reverse pushing element (B), moves from the rising position (PS) to corresponding different falling positions, so as to position the reverse pushing element (B) at different heights relative to the conveyor (C), thereby accommodating any dimensional changes of the product (P) or the product group (P).

[0087] Therefore, the pushing device (100) of the present invention is flexible and can adapt to possible size variations of the product or product group to be conveyed without resorting to component replacement and / or adjustment, but simply by positioning the second and third brackets at different distances from each other.

[0088] In the preferred embodiment shown in the figure, the first tray (1) is arranged in front of the third tray (3) relative to the conveyor (C) of the product (P) or product group (P) to be pushed and conveyed along the conveying direction (Z) transverse to the conveyor (C), wherein the second tray (2) is arranged between the first tray (1) and the third tray (3).

[0089] Other arrangements of the bracket are also possible.

[0090] In the preferred embodiment shown in the figure, the hinge system (5) is configured to include:

[0091] The first arm (51) is mounted on the second bracket (2) in a manner parallel to the straight guide rail (R);

[0092] The second arm (52) is mounted on the third bracket (3) in a manner parallel to the straight guide rail (R) and the first arm (51);

[0093] At least one pair of rods (53, 54) are hinged at their respective first ends to the second arm (52) and at their respective second ends to the second support member (20) so that they are parallel to each other;

[0094] A lever (55) is hinged at a first end to the first arm (51) and at a second end to at least one of the pair of rods (53, 54).

[0095] In the illustrated embodiment, the lever (55) is hinged to the end of the first arm (51) and the rear bar (54) of a pair of bars (53, 54) (relative to the position of the conveyor).

[0096] Other arrangements are also possible, for example, the rod (55) can be hinged to the front rod (53) of a pair of rods (53, 54), or to another position on the first arm (51).

[0097] The pair of rods (53, 54) enable the second support (20) to remain parallel to the first support (10) and vice versa during the movement of the second support (20) and thus the reverse pushing element (B) from the rising position (PS) to the falling position (PA).

[0098] The movement of the second support is made possible by the relative movement between the first arm (51) and the second arm (53) (following the relative movement of the second bracket and the third bracket moving away from each other), which causes the lever (55) to rotate, thereby causing the pair of rods to rotate.

[0099] In the figures, the second support (20) has an L-shape, the first arm of which is an arm of a pair of rods hinged together to remain parallel to the first support (10), and the second arm of which supports the reverse push element (B).

[0100] exist Figures 2 to 12 In the preferred embodiment shown, the pushing device (100) can be implemented by further including:

[0101] The fourth bracket (4) is slidably mounted on the straight guide rail (R) and includes a permanent magnet (41);

[0102] The hopper (6) is adapted to include a channel (60) for passing through a product (P) or product group (P) to be inserted into a container (V), the container (V) being arranged on a second conveyor (C2) located on one side of the conveyor of the product (P) or product group (P).

[0103] The third support element (40) is mounted on the fourth bracket (4) in a manner parallel to the straight guide rail (R).

[0104] The fourth bracket (4) is located at the rear of all three brackets (the first, second and third brackets) and at the corresponding retracted position along the straight guide rail (R), wherein the length of the third support member (40) is such that the hopper (6) is located between the conveyor (C) of the product (P) or product group (P) and the second conveyor (C2).

[0105] The stator (S) can be activated to generate a variable magnetic field along the straight guide rail (R), causing the fourth carriage (4) to move from its retracted position toward the conveyor (C) approaching the product (P) or product group (P), so that the hopper (6) moves toward the opening of the container (V) for insertion into which the product (P) or product group (P) is inserted. Once insertion has been made, the fourth carriage (4) can be moved back to its retracted initial position.
