Detailed Description
The following further description is made with reference to the embodiments shown in the drawings.
The automatic packaging device for the paper box shown in figures 1 to 3 is used for loading columnar materials into the paper box to realize automatic loading and automatic packaging. Wherein, the paper boxes 7 conveyed by the belt conveyor of the paper box conveying mechanism are horizontally and intermittently conveyed from left to right (the conveying direction is shown as an arrow direction X in figures 1 and 12); the opening of the carton comprises two side tongues 72 at the left and right sides of the box, a tongue 71 at the lower side of the box and ears 73 at the outer edge of the tongue (as shown in fig. 11). The automatic packaging device comprises a workbench 8, and a feeding mechanism 1, a pushing mechanism 2, a first folding side tongue mechanism 3A, a second folding side tongue mechanism 3B, a big tongue folding mechanism 4, a tongue folding auxiliary mechanism 5 and a side tongue folding transmission mechanism 6 which are respectively arranged on the workbench. The first folding side tongue mechanism and the second folding side tongue mechanism have the same structure; the first folding side tongue mechanism, the pushing mechanism, the second folding side tongue mechanism, the tongue folding auxiliary mechanism and the big tongue folding mechanism are sequentially arranged from left to right (as shown by an arrow X in figure 1).
As shown in fig. 4, the feed mechanism is used to feed material 9 (i.e., products packaged in cartons), and the present invention employs a belt conveyor. The belt conveyor comprises a support frame 11, a conveyor belt 14, a driving shaft, a driven shaft and a feeding motor 13 (the driving shaft and the driven shaft are not shown in the figure). The support frame is fixed on a workbench (the workbench is supported by a frame); the conveyor belts are horizontally arranged in the left-right direction (see fig. 3) so as to convey materials; the driving shaft and the driven shaft are respectively and rotatably positioned on the support frame and are respectively provided with a belt wheel for supporting the conveying belt; the feeding motor is fixed on the support frame to drive the driving shaft to rotate. The surface of the conveyor belt is fixed with a plurality of partition plates 12 which are arranged at equal intervals in the length direction of the conveyor belt so as to ensure that materials enter the material pushing mechanism at the same time interval. The belt conveyor described above is available commercially.
The paper box conveying mechanism is a belt conveyor (the belt conveyor is clear in the drawing and the paper box conveying mechanism is omitted in the drawing) which is the same as the feeding mechanism; the belt conveyor is fixed on the frame, and the conveyor belt is arranged along one side edge of the workbench (parallel to the conveyor belt of the feeding mechanism); the distance between the partition boards on the conveying belt is the same as that of the partition boards on the conveying belt of the feeding mechanism, so that the paper boxes correspond to the packaged materials one by one. After the paper box is transversely placed on the conveying belt (the central line of the paper box is vertical to the length direction of the conveying belt), the side tongues, the large tongues and the ears are all hung outside the conveying belt, so that all mechanisms can conveniently turn over the parts.
As shown in fig. 5 and 6, the material pushing mechanism is used for receiving the material in the material feeding mechanism and pushing the material into the carton; the pushing mechanism comprises a pushing slide rail 211, a pushing slide block 29, a pushing rod 210, a connecting rod assembly, a pushing motor 22 and a material channel 28. The pushing slide rails are horizontally arranged and are fixed on the workbench perpendicular to the conveying direction of the paper boxes; the pushing sliding block is slidably positioned on the pushing sliding rail; the material pushing rod is fixedly connected with the material pushing sliding block and extends upwards into the material channel so as to push the material; the material pushing motor drives the material pushing rod to move through the connecting rod assembly. The link assembly includes a link mounting plate 21, a first link 23, a second link 24, a third link 25, a fourth link 26, and a fifth link 27. The connecting rod mounting plate is fixed below the workbench to support the material pushing motor; the first connecting rod is used as a driving rod, is fixed with a motor shaft of the pushing motor and is driven by the pushing motor; one end of the second connecting rod is hinged with the first connecting rod, and the other end of the second connecting rod is hinged to the middle part of the third connecting rod; one end of the third connecting rod is hinged to the connecting rod mounting plate, and the other end of the third connecting rod is hinged to the fourth connecting rod; one end of the fifth connecting rod is hinged to the fourth connecting rod, and the other end of the fifth connecting rod penetrates through the workbench to be fixedly connected with the material pushing rod.
The material channel is arranged at the outlet of the belt conveyor to receive the material; the material channel is fixed right above the material pushing slide rail, and the outlet of the material channel is aligned with the paper box, so that the material can accurately enter the paper box. An opening 283 is formed in one side of the material channel corresponding to the belt conveyor, so that the interference between the baffle on the conveying belt and the side surface of the material channel is avoided. A material pushing groove 281 is formed in the middle of the material channel, and the material pushing rod can conveniently extend into the material channel; the two sides of the material pushing groove are provided with slopes 282 to facilitate automatic centering of materials. The outlet of the material channel is provided with a tongue pressing bending rod 29 which extends leftwards, the tongue pressing bending rod bends downwards along the left-right direction, when the paper box passes through the material channel, the big tongue is positioned below the tongue pressing bending rod and turns downwards under the limiting effect of the tongue pressing bending rod, and therefore the situation that the big tongue blocks the material entering the box is avoided.
As shown in fig. 7, each of the first folding tongue mechanism and the second folding tongue mechanism includes a folding tongue mounting bracket 31, a bearing with a seat 33, a folding tongue rotating shaft 34, a rocker arm 35, a folding tongue swing rod 32, and a tucking screw 36. The folding side tongue mounting rack is fixed on the workbench; the bearing with the seat is fixed on the folding side tongue mounting rack; the folding side tongue rotating shaft is rotatably positioned in the bearing with the seat; the rocker arm and the folding side tongue swing rod are respectively fixed at two ends of the folding side tongue rotating shaft; the driving plug screw is fixed on the rocker arm and is connected with the side folding tongue transmission mechanism in a matching way. When the folding side tongue swinging mechanism works, the folding side tongue transmission mechanism drives the rocker arm to swing through the tucking screw, and the rocker arm drives the folding side tongue swinging rod to swing through the folding side tongue rotating shaft, so that the side tongue is folded. The side tongue folding swing rod in the first side tongue folding mechanism is positioned between the two side tongues and drives the side tongues to be folded outwards so as to facilitate the materials to enter the paper box; and a side tongue folding swing rod in the second side tongue folding mechanism is positioned outside the side tongue and drives the side tongue to be folded inwards to a certain angle, so that the subsequent paper box packaging work is facilitated.
As shown in fig. 8, the tongue folding mechanism is used for folding over the ears and the tongue so as to close and seal the carton. The big tongue folding mechanism comprises a first bearing seat 43, a second bearing seat 49, a first rotating shaft 42, a second rotating shaft 410, a four-bar linkage structure, a first inserting piece 45, a second inserting piece 47 and a tongue folding motor 41. The first bearing seat and the second bearing seat are respectively fixed on the workbench; the first rotating shaft and the second rotating shaft are respectively and rotatably positioned in the first bearing seat and the second bearing seat, wherein the first rotating shaft is driven by the tongue folding motor, and the first rotating shaft drives the second rotating shaft to rotate through the four-bar structure. The four-bar linkage structure comprises a first crank 44, a tab mounting bar 46 and a second crank 48; one end of the first crank is fixedly connected with the first rotating shaft, and the other end of the first crank is hinged with the inserting sheet mounting rod; the other end of the inserting sheet mounting rod is hinged with the second crank; the other end of the second crank is fixedly connected with the second rotating shaft. The first inserting piece and the second inserting piece are fixedly arranged on the inserting piece mounting rod and do reciprocating circular motion along with the inserting piece mounting rod; the second inserting sheet is positioned on the left side of the first inserting sheet. When the paper box is in work, the second inserting piece firstly turns the ears of the paper box inwards, then the first inserting piece pushes the big tongue forwards, so that the ears of the paper box are inserted into the paper box, and the covering and sealing of the paper box are realized. The bottom of the second inserting piece is flush with the bottom of the ear; the bottom of the first inserting piece is lower than that of the second inserting piece so as to ensure that the first inserting piece can push the large tongue to be folded inwards.
As shown in fig. 9, the tongue folding auxiliary mechanism is used for limiting the large tongue to match the operation of the tongue folding mechanism, and includes a tongue folding auxiliary mounting frame 51, a tongue lifting bent rod 54, a tongue folding sloping plate 52 and a side tongue pressing strip 53. The auxiliary folding tongue mounting frame is fixed on the workbench; the tongue lifting bent rod is fixed on the tongue folding auxiliary mounting frame and is bent upwards along the left and right directions; the folded lug sloping plate is obliquely fixed on the folded tongue auxiliary mounting frame and is matched with the bent rod of the raised tongue so as to limit the large tongue. The ear folding inclined plate is provided with an ear folding opening 521 which is just positioned on the motion track of the second insertion piece so as to ensure that the second insertion piece is folded inwards when crossing the ear folding opening. The side tongue pressing strip is fixed on the auxiliary folding tongue mounting frame so as to fold the side tongue inwards. In the working process, the side tongues of the paper box are turned inwards by a certain angle after passing through the second side tongue folding mechanism, and when the paper box is continuously conveyed rightwards until contacting the side tongue pressing strips, the side tongues are further turned inwards to a final box closing state (as shown in fig. 14) under the blocking action of the side tongue pressing strips; meanwhile, the big tongue of the paper box is lifted upwards for a certain angle along the tongue lifting bent rod and limited by the lug folding inclined plate (at the moment, the big tongue is positioned between the tongue lifting bent rod and the lug folding inclined plate). When the paper box passes through the ear folding openings of the ear folding sloping plates, the second inserting pieces just cross the ear folding openings and fold the ears of the paper box inwards (as shown in figure 15). In order to avoid damage caused when the side tongue is contacted with the side tongue pressing strip, the left side of the side tongue pressing strip is set to be in a transitional arc shape.
As shown in fig. 10, the side folding tongue transmission mechanism is disposed between the big folding tongue mechanism and the side folding tongue mechanism, so that the big folding tongue mechanism drives the side folding tongue mechanism to move. The folding side tongue transmission mechanism comprises a first transmission rod 61, a second transmission rod 62, a transmission guide rail 66, a first chute plate 64, a second chute plate 65 and a slide block linkage plate 63. The transmission guide rail is fixed below the workbench; the first sliding groove plate and the second sliding groove plate are slidably positioned on the transmission guide rail through a sliding block and are fixedly connected into a whole through a sliding block linkage plate; one end of the first transmission rod is fixedly connected with the second rotating shaft, and the other end of the first transmission rod is hinged with the second transmission rod; the other end of the second transmission rod is fixedly connected with the sliding block linkage plate, so that the second rotating shaft indirectly drives the first sliding groove plate and the second sliding groove plate to move. The upper parts of the first sliding chute plate and the second sliding chute plate are both provided with sliding chutes 67, and the tamping screws can be slidably positioned in the sliding chutes to drive the rocker arms to swing; the first sliding groove plate penetrates through the workbench upwards and then is in sliding fit with a tucking screw in the second folding side tongue mechanism; the second sliding groove plate penetrates through the workbench upwards and then is in sliding fit with the plugging screw of the first folding side tongue mechanism.
The belt conveyor, the pushing motor and the tongue folding motor are respectively and electrically connected with a PLC (programmable logic controller) (not shown) so as to ensure the working cooperation of all the mechanisms.
The working principle of the invention is as follows:
before work, the paper boxes are conveyed horizontally and intermittently along the X direction by the paper box conveying mechanism; the material is conveyed into the material channel by the feeding mechanism; the tongue folding motor drives the second rotating shaft to rotate through the four-connecting-rod structure and simultaneously drives the first inserting piece and the second inserting piece on the inserting piece mounting plate to do reciprocating circular motion; the second rotating shaft drives the first sliding chute plate and the second sliding chute plate to slide along the transmission guide rail through the first transmission rod and the second transmission rod, and the sliding chutes of the first sliding chute plate and the second sliding chute plate are in sliding fit with the tucking screws fixed on the rocker arms, so that the folding lateral tongue oscillating bars in the first folding lateral tongue mechanism and the second folding lateral tongue mechanism are driven to swing back and forth within a certain angle.
In operation, the condition of the carton is as shown in figure 12. When the paper box passes through the first side tongue folding mechanism, the large tongue of the paper box is folded downwards along the tongue pressing bending rod, and the two side tongues of the paper box are folded outwards under the action of the side tongue folding swing rod in the first side tongue folding mechanism, so that the paper box is in a box opening state (as shown in figure 13) and materials can smoothly enter the paper box. When the paper box passes through the material channel, the material pushing rod pushes the material in the material channel into the paper box under the driving of the material pushing motor, then the paper box is continuously conveyed rightwards, and meanwhile, the material pushing rod is reset. When the paper box passes through the second folding lateral tongue mechanism, the two lateral tongues are folded inwards by a certain angle under the action of a lateral tongue folding swing rod in the second folding lateral tongue mechanism. When the paper box passes through the tongue folding auxiliary mechanism, the two side tongues are further turned inwards under the action of the side tongue pressing strips (as shown in fig. 14), and meanwhile, the large tongue of the paper box is lifted upwards for a certain angle along the tongue lifting bent rod and is limited by the lug folding inclined plate. When the paper box passes through the ear folding openings of the ear folding sloping plates, the second inserting pieces just cross the ear folding openings and fold the ears of the paper box inwards to realize ear folding (as shown in fig. 15). When the paper box passes through the first inserting sheet, the first inserting sheet pushes the big tongue to move forwards, so that the ears are inserted into the paper box (as shown in fig. 16), and the covering and sealing of the paper box are realized, and the packaging work is completed.
It should be noted that the operation objects of the mechanisms in the above description are paper boxes with one end closed (which have been processed in advance-folded and closed) and the other end opened; the pretreatment can also be carried out on the device provided by the invention, or a set of device similar to the device provided by the invention is added before the device (the feeding mechanism, the material pushing mechanism and the first folding lateral tongue mechanism are deleted in the device, and the stations are advanced by about two). Thereby completing the packaging of the entire carton.
Finally, it should be noted that the above-mentioned list is only a specific embodiment of the present invention. Obviously, the present invention is not limited to the above embodiments, and many modifications are possible, such as changing the installation position of the motor, changing the shape of the parts, changing the transmission manner, and the like.
