Description

Technical Field

[0001] The invention relates to the field of electromechanical control technology, and in particular to an automatic sleeve packaging device. Background Art

[0002] Product packaging is not only the outer layer of the product, but also a bridge for communication between the brand and consumers. With the development of social economy and the advancement of science and technology, product packaging has evolved from a simple protective function to delivering brand value, enhancing consumer experience and environmentally friendly sustainable development. An envelope is a decorative paper tape wrapped around a product. It is usually wrapped outside the product to play a decorative and protective role, and can be printed with relevant information about the product. As a common type of packaging, envelopes are especially common in ready-to-eat foods, prepared foods, dairy products, daily necessities, electronic products and books.

[0003] Compared with carton packaging, envelope packaging has a simpler structure, fits the product better, uses less packaging materials, and is more economical and environmentally friendly than carton packaging. Envelope packaging can be divided into two major types: the first is flat paper type, in which the envelope tape is pasted with hot melt adhesive after the product is wrapped during the packaging process; the second is pre-pasted type, in which the envelope has been pre-pasted in the printing factory, and the envelope paper is formed into a tube, and the product can be directly inserted into the envelope. Compared with the first type of envelope, the second type of envelope allows product manufacturers to paste without the help of equipment or tools, reducing manufacturers' investment in equipment and avoiding the risks and controls of using pasting equipment.

DETAILED DESCRIPTION

[0022] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0023] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art. Example

[0024] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] This specific embodiment is only an explanation of the present invention, not a limitation of the present invention. Any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of this application.

[0026] This embodiment relates to a sleeve packaging device, such as Figure 1 , Figure 2 As shown, it includes: an inlet conveying component combined with a blocking device A, a secondary positioning and sorting conveyor component B, a sleeve device component C, an envelope storage device component D, an upper suction sleeve component E, a lower suction sleeve component F, a support and introduction device component combined with an auxiliary molding device component G, an output conveyor component H, and a frame component I.

[0027] It should be noted that: the aforementioned A represents the overall structure composed of the inlet conveying component and the blocking device; the aforementioned G represents the overall structure composed of the introduction device component and the auxiliary molding device component.

[0028] like Figure 1 , 3As shown, the inlet conveying assembly is combined with the blocking device A and is located at the product entry end of the equipment. The inlet motor 1 installed on the first fixed plate 44 is combined with the transmission synchronous wheel 2 installed on the output end of the first fixed plate 44. The driven synchronous wheel 3 is driven based on the transmission synchronous belt 4. The driven synchronous wheel 3 is installed on the belt entry drive shaft 5. The driving pulley 6 is installed on the belt entry drive shaft 5. The driving pulley 6 drives the driven pulley 7 through the inlet conveyor belt 9. The inlet conveyor belt 9 is installed with an inlet belt support plate 8. Among them, the other end of the belt entry drive shaft 5 is installed on the second fixed plate 45, and the driving pulley 6, the driven pulley 7, the inlet belt support plate 8, the inlet conveyor belt 9, and the blocking cylinder 10 are respectively installed on the first movable plate 24 and the second movable plate 25. The inlet conveying assembly is responsible for the product input function in the equipment, and can be connected to the front-end assembly line to form unmanned automation. When the sleeve sealing machine fails, the blocking cylinder 10 extends, and the blocking block 11 installed on its head prevents the product from continuing to flow into the equipment to prevent the product from accumulating and causing greater failures and damage to the product.

[0029] In this embodiment, the entrance conveying components are respectively installed on the first movable plate 24 and the second movable plate 25. For products of different widths entering the equipment, the first movable plate 24 and the second movable plate 25 can be adjusted by simply turning the width adjustment hand wheel, so as to adapt to products of different widths and achieve quick adjustment.

[0030] like Figure 4 As shown, the secondary positioning and sorting conveyor assembly B is connected to the inlet conveying assembly, and the sorting motor 12 installed on the column motor plate 20 drives the column drive shaft 15, and the column drive pulley 13 is installed on the column drive shaft 15. The column drive pulley 13 drives the column driven pulley 14 installed on the column driven shaft 16 by driving the column belt 17 to form a conveying structure; the column motor plate 20 is connected to the column mounting plate 21 through the column connecting plate 22, and the column belt support plate 23 is installed on the column connecting plate surface 22, close to the column belt 17 to prevent the belt from deviating and tighten the belt to the product; the column tensioning wheel 18 is installed on the column tensioning shaft 19, and the column tensioning shaft 19 is respectively installed on the column motor plate 20 and the column mounting plate 21 to adjust the tension of the column belt 17. The above constitutes an integral single module of the entire secondary positioning and sorting conveyor assembly B.

[0031] There are two secondary positioning and sorting conveyor assemblies B, which are respectively installed on the first movable plate 24 and the second movable plate 25. For products of different widths entering the equipment, the first movable plate 24 and the second movable plate 25 can be adjusted by turning the width adjustment hand wheel, so as to adapt to products of different widths and realize quick adjustment.

[0032] like Figure 5As shown, the main structural components of the sleeve-envelope device assembly C are: the sleeve-envelope plate 43 is respectively mounted on the first fixing plate 44 and the second fixing plate 45 through the first middle plate support shaft 46 and the second middle plate support shaft 47 fixed thereon, so as to form support and fixation. Figure 5 The final moving parts, the sleeve sleeve chain 31 and the round belt 37, installed on the sleeve sleeve plate 43, cooperate with the sleeve sleeve transmission motor 26 and the motor synchronous wheel 38 installed thereon to drive the "chain drive synchronous wheel 39 corresponding to the sleeve sleeve chain 31" and the "round belt drive synchronous wheel 40 corresponding to the round belt 37" to drive the corresponding sleeve sleeve drive shaft 27 and the round belt drive shaft 34, and drive the sleeve sleeve transmission sprocket 28 and the round belt driving wheel 33 installed thereon. The sleeve sleeve transmission sprocket 28 drives the sleeve sleeve driven sprocket 29 through the sleeve sleeve chain 31 to form an operating mechanism, and the round belt driving wheel 33 drives the first round belt wheel 35 and the second round belt wheel 36 through the round belt 37 to form an operating mechanism. The ultimate purpose of the above parts structure combination is to make the linear speed of the sleeve sleeve chain 31 and the round belt 37 consistent, so that when the product is moved thereby, there will be no relative displacement, so that the product and the sleeve are in a set relative position and are transported together to the output conveyor assembly H. The second synchronous belt tensioning wheel 42 is used to increase the angle of the transmission synchronous belt to the motor synchronous wheel 38, and the first synchronous belt tensioning wheel 41 is used to tighten the transmission synchronous belt. The push plate 32 is installed on the sleeve chain 31 and is used to push the product into the sleeve.

[0033] like Figure 1 , Figure 6As shown, the envelope storage device assembly D is on one side of the equipment and is used to store pre-folded envelopes. The envelope lower support assembly 48 is used to support the lower end of the envelope. The lower support mounting plate 48H is equipped with a lower support adjustment guide rail 48C for quick and easy adjustment of the length direction of the corresponding product envelope. The slider of the guide rail is equipped with an envelope lower support bar 48A. The adjustment lock block 48D is used to quickly lock or loosen the envelope lower support bar 48A. The lower support bar is equipped with a lower support limit bar 48B to limit the side of the envelope so that the envelope can be accurately sucked out by the upper suction envelope assembly E and placed in a suitable position. The lower support limit bar 48B side fixes the envelope pressing optical axis 48F. The envelope pressing optical axis 48F is equipped with an envelope pressing block 48G, which is used to press the pre-folded envelope in the envelope storage device assembly D. When the envelope in the storage device is taken away by the upper suction envelope assembly E, the envelope automatically flows forward to fill the vacant position taken away. The function of the upper limit assembly 49 of the envelope is to limit the upper end of the envelope so that the envelope can be accurately taken out by the upper suction envelope assembly E; the upper limit member 49A of the envelope and the upper support member 49B of the envelope installed thereon correspond to the upper end and the upper side end of the envelope respectively, and the upper limit member 49A of the envelope is installed on the upper limit mounting plate 49J; the upper limit mounting plate 49J and the envelope upper limit adjustment optical axis 49C, the envelope upper limit adjustment screw 49D, the screw handle 49E, the screw position indicator 49F, and the optical axis linear bearing 49G constitute the quick adjustment component of the upper limit assembly 49 of the envelope, and the width of the corresponding product corresponding to the upper limit of the corresponding envelope can be adjusted by twisting the screw handle 49E. The envelope lower support assembly 48 and the envelope upper limit assembly 49 are connected to form an integrated assembly through the upper limit mounting block 49I; the upper limit upper clamping block 49H and the lower limit front clamping block 48E are installed at the front end of the outlet of the integrated assembly to limit the accidental falling off of the envelope. The lower support mounting block 48H is equipped with: an envelope height adjustment assembly 50 consisting of a height adjustment screw rod 50A, a height adjustment optical axis 50B, a height linear bearing 50C, a height adjustment reducer 50D, and a height reducer plate 50E, which can quickly adjust the bottom height of the envelope. The envelope height adjustment assembly 50 is connected by an envelope mounting plate 51 and an envelope mounting vertical plate 52 to form an integral module assembly.

[0034] In this embodiment, as described above, the envelope storage device assembly D can store pre-folded envelopes and implement a quick adjustment function for envelopes of different sizes.

[0035] like Figure 7As shown, the upper suction envelope assembly E is provided with longitudinal movement by the longitudinal module driving assembly 53A, the longitudinal module 53A is driven by the module motor 53B, and is installed on the module mounting member 54, the longitudinal module 53A is installed with a transfer assembly 55B, one end of the transfer assembly 55B is installed with a rotating motor 55A, which provides rotational power, the rotating motor 55A is connected in series with the rotating shaft 55F in the transfer assembly 55B by a coupling, the rotating shaft 55F is installed with an air slip ring 55E, the suction plate 56 is installed on the rotating shaft 55F, the suction cup assembly 57 is installed on the suction plate 56, the electromagnetic valve group 55C is installed on the side of the transfer assembly 55B, and the vacuum generator group 55D is installed on the upper end, the compressed air enters the electromagnetic valve through the return plate under the electromagnetic valve group 55C, the electromagnetic valve controls the output compressed air to pass into the vacuum generator group 55D to generate vacuum, the vacuum generated by the vacuum generator 55D passes into the fixed end of the air slip ring 55E, and is output to the suction cup assembly 57 through the rotating end of the air slip ring 55E. The above connection enables each group of suction cup components to independently control the vacuum of the suction envelope, and the conveying air pipe will not be entangled.

[0036] like Figure 8 As shown, the lower suction sleeve assembly F is powered by a driving motor 58 mounted on the first fixed plate 44, and a driving flange 59A is mounted on the head of the driving motor 58, and a driving connecting rod 59B is used to connect the connecting rod swing arm 59C to form a crank rocker structure. The connecting rod swing arm 59C swings back and forth within the required angle to drive the swing shaft 59D. The swing arm 58E is mounted on the swing shaft 59D, which is connected to the swing connecting rod 59F. The other end of the swing connecting rod 59F is connected to the lower suction block 61. The lower suction block 61 is fixed on the lower suction guide rail assembly 60, so that the lower suction block 61 moves up and down along the guide rail, forming the action of "sucking the sleeve up, pulling it down to form it and placing it on the sleeve device assembly C". The suction cup group 62 is mounted on the lower suction block 61. There are two groups of lower suction guide rails 60, lower suction blocks 61 and suction cup groups 62, which are respectively mounted on the first movable plate 24 and the second movable plate 25.

[0037] like Fig. 9As shown, two mutually symmetrical groups of opening and introducing device components combined with auxiliary molding device components G are respectively installed on the first movable plate 24 and the second movable plate 25 by auxiliary mounting plates 65D, and two optical axis fixing blocks 65B are installed on the auxiliary mounting plate 65D. The two optical axis fixing blocks 65B are connected to each other using two adjusting optical axes 65C, so that the adjusting optical axes 65C act as the adjusting guide rails of the components; the opening moving parts 65A and the molding part adjusting parts 68 are installed on the two adjusting optical axes 65C on one side, and the opening and introducing device components combined with the auxiliary molding device components G can be adjusted separately. The expansion adjustment block 63B is installed on the expansion moving part 65A to adjust the auxiliary expansion introduction device in the vertical direction. The expansion installation block 63C is installed on the expansion adjustment block 63B. The expansion installation block 63C is installed with the guide member 63A, which plays the role of guiding the product in the equipment. The expansion cylinder 64 and the cylinder head expansion member 66 are installed. When the envelope is sucked down by the lower suction envelope assembly F and placed on the envelope device assembly C, the expansion cylinder 64 acts to open the cylinder head expansion member 66, expand the envelope edge, and play a guiding role, so that the product flows smoothly into the envelope. The molding member adjustment member 68 has two pieces on one side, which are installed on the two adjustment optical axes 65C. The front side is installed with an auxiliary molding member 67. The auxiliary molding member 67 is used to shape the envelope according to the shape required for packaging and ensure that the posture after molding remains unchanged, so that the product can enter the envelope smoothly.

[0038] like Figure 5 , Fig.10 As shown, there are two symmetrical groups of output conveyor components H, which are respectively installed on the first movable plate 24 and the second movable plate 25. The conveyor power is provided by the sleeve transmission motor 26, which drives the transmission synchronous wheel 69 through the synchronous belt to coaxially drive the belt output drive shaft 70. A driving pulley 71 is installed on the belt output drive shaft 70. The driving pulley 71 drives the driven pulley 72 through the outlet conveyor belt 74 to form a conveying structure. The outlet belt support plate 73 is respectively installed on the first movable plate 24 and the second movable plate 25 to support the outlet conveyor belt 74 for correcting the deviation.

[0039] like Fig.11The figure shows the assembly diagram of the various components of the envelope machine. The inlet conveying assembly combined with the blocking device A, the secondary positioning and arranging conveyor assembly B, the lower suction envelope assembly F, and the output conveyor assembly H are all installed on the first movable plate 24 and the second movable plate 25. The upper suction envelope assembly E is a gantry structure, which is installed on the first fixed plate 82 and the second fixed plate 83 respectively. The envelope storage device assembly D is installed on the second fixed plate 83. The first movable plate 24 and the second movable plate 25 are installed on the first fixed plate 44 and the second fixed plate 45 by means of adjusting screw rods 76, positive thread nut 77A, negative thread nut 77B, main drive screw rod 78, adjusting optical axis 80 and adjusting linear bearing 81; the main drive screw rod 78 and the two adjusting screw rods 76 are equipped with adjusting sprockets 75A at the heads, and the adjusting chain 75B connects the sprockets 75A in series, and the adjusting hand wheel 79 is fixed at the end of the main drive screw rod 78. Through the above structure, the relative positions of the first movable plate 24 and the second movable plate 25 can be quickly adjusted by turning the adjusting hand wheel 79, so as to quickly adjust the corresponding product width.

[0040] like Fig.12 As shown, the frame component I includes a frame 84, and all components of the equipment are installed on the frame 84; the protection door 85 is used to prevent operators from intruding into the operating components during the operation of the equipment to prevent accidents; the human-machine operation screen component 86 is the human-machine interaction component of the equipment, and the equipment start, stop and setting of various parameters are all completed on this component.

[0041] For the sleeve-envelope packaging equipment described in the first embodiment, the automatic sleeve-envelope packaging equipment is provided with an envelope storage device assembly. Since the envelope storage device assembly is equipped with a guide and limit mechanism, it ensures that the envelopes are in a consistent posture and position for subsequent material picking operations; in addition, the envelope storage device assembly also provides a rapid adjustment function, which can be quickly adjusted for envelopes of different specifications and types. Compared with traditional sleeve-envelope packaging equipment, the adjustment time is greatly reduced; For the sleeve-envelope packaging equipment described in the first embodiment, the automatic sleeve-envelope packaging equipment is provided with an upper suction sleeve-envelope assembly and a lower suction sleeve-envelope assembly; based on the upper suction sleeve-envelope assembly, "removal of the envelope" and "preliminary positioning of the envelope" can be realized, and based on the lower suction sleeve-envelope assembly, "further expansion of the envelope" can be realized. Compared with the traditional sleeve-envelope packaging equipment, the present application optimizes the envelope expansion process, which can make the envelope expand smoothly and avoid "failure of the envelope to form leading to subsequent failure and shutdown"; For the sleeve-encapsulating packaging equipment described in the first embodiment, the automatic sleeve-encapsulating packaging equipment is provided with an inlet conveying assembly and a blocking device; based on the blocking device, it is possible to achieve: when the sleeve encapsulating machine fails, the product is blocked from continuing to flow into the sleeve encapsulating machine, and part of the products to be encapsulated are buffered for a short period of time to avoid the front-end assembly line from stopping; For the sleeve packaging equipment described in the aforementioned embodiment 1, the automatic sleeve packaging equipment is provided with a secondary positioning and arranging conveyor, a sleeve device assembly, and a propping-up introduction device assembly. The secondary positioning and arranging conveyor can perform secondary positioning in the width direction of the products flowing into the sleeve machine. The sleeve device assembly cooperates with the propping-up introduction device assembly to enable the product to be perfectly sleeved into the envelope, so that the envelope stays at a preset position of the product and is output to the outside of the sleeve machine; thereby improving the stability of the packaging envelope to reduce the failure rate of the equipment.

[0042] The working principle and action steps of this equipment are as follows: The envelope machine is an automated device that automatically puts envelopes into products. The operator pulls up the envelope pressing block 48G in the envelope storage device component D, puts in the pre-folded envelope, and then drops the envelope pressing block 48G, so that the lower end of the envelope is close to the lower limit front block 48E, and the upper end is close to the upper limit upper block 49H. Start the equipment, and the longitudinal module 53A in the upper suction envelope component E moves longitudinally to the suction cup component 57, close to the lower limit front block 48E and the upper limit upper block 49H of the envelope storage device component D, absorbs the envelope, and then moves in the opposite direction to make the envelope detach from the envelope storage device component D, and continues to move to the preset relative position above the envelope device component C, and the suction plate component 56 rotates to move the envelope to the level below and wait. After the product flows into the equipment from the entrance conveying component combined with the blocking device A, it avoids the push plate 32 of the sleeve device component C that moves in the middle of the secondary positioning and sorting conveyor component B at the corresponding time, and then enters the secondary positioning and sorting conveyor component B to reposition the left and right positions of the product, and stays at the end of the conveying direction of the secondary positioning and sorting conveyor component B. From the above, it can be seen that the entrance conveying component combined with the blocking device A not only undertakes the function of receiving the products flowing into the equipment, but also has the function of timed feeding to prevent the push plate 32 from damaging the product and the equipment.

[0043] After the equipment detects that the product has reached the end through the photoelectric sensor, the lower suction sleeve assembly F moves upward until the suction cup group 62 is close to the lower end of the envelope and then absorbs the envelope and moves downward. The suction cup assembly 57 of the upper suction sleeve assembly E continues to absorb the upper end of the envelope until it cooperates with the downward movement of the lower suction sleeve assembly F to completely pull open the formed envelope, and then the suction cup assembly 57 disconnects the vacuum and releases the upper end of the envelope; the lower suction sleeve assembly F absorbs the envelope until the lower end of the envelope reaches the round belt 37 surface of the sleeve sleeve device assembly C and maintains absorption, the auxiliary molding part 67 assists the envelope in forming a shape suitable for inserting the product, and the opening cylinder 64 drives the cylinder head opening part 66 to open the edge of the envelope for the product to flow into the envelope; when After the push plate 32 moves to contact the product, the secondary positioning and arranging conveyor assembly B is started again, and the product continues to be moved toward the exit direction synchronously with the push plate 32, and enters the envelope after passing through the guide piece 63A and the cylinder head expansion piece 66. When the product enters the envelope to the required packaging position (that is, the envelope is in the front section, middle section, end, etc. of the product), the suction cup group 62 of the lower suction envelope assembly F disconnects the vacuum and disengages the suction of the envelope, and descends again until the end of the suction cup of the suction cup group is completely separated from the envelope, so that the movement of the envelope does not rub against the suction cup, and then stops and waits for the next product to flow into the end of the conveying direction of the secondary positioning and arranging conveyor assembly B and then starts the action cycle again.

[0044] The push plate 32 of the sleeve wrapping device assembly C and the round belt 37 are synchronously assisted by the auxiliary forming member 67 to convey the product to the output conveyor assembly H; the output conveyor assembly H continues to convey the product completely out of the sleeve wrapping machine with the assistance of the auxiliary forming member 67.
