Description

Technical Field

[0001] The utility model relates to the technical field of packaging bags, in particular to a bag sorting machine. Background Art

[0002] For sheet products, such as flat prints, packaging bags, paper, etc., after production, they usually need to go through stacking, sorting, packaging and bundling processes, and different processes need to be equipped with corresponding equipment to complete. At present, a stacking and sorting device is generally set at the discharge port of the bag making machine to stack the products into stacks, and a conveying platform is set in front of the stacking and sorting device to transfer the product stacks to the bundling device, and then a conveying device is set in front of the bundling device to convey the product stacks to the designated position through the conveying device. For the stacking and sorting of sheet products, the upper and lower receiving plates are usually used to receive materials in turn. The lower receiving plate receives the conveyed sheet products and stacks them into stacks. When the count of the sheet products received by the lower receiving plate reaches the set value, the upper receiving plate extends above the lower receiving plate to temporarily receive the conveyed sheet products instead of the lower receiving plate; the lower receiving plate is retracted, and the stacked sheet products fall onto the stacking material conveying mechanism below, and then the lower receiving plate is extended again, and the upper receiving plate is retracted, and the sheet products temporarily received by the upper receiving plate fall onto the lower receiving plate. The lower receiving plate is pulled out from the bottom of the sheet products, which may cause scratches and other defects on the bottom surface of the sheet products at the bottom layer. In addition, when the lower receiving plate is retracted, the stacked sheet products on the lower receiving plate fall onto the stacking material conveying mechanism below, which may cause the stacked sheet products to become scattered. Before bundling, the products are in an unrestrained state on the conveying platform, which affects the bundling effect. The various devices are placed in sequence, which takes up a lot of space.

[0041] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0042] Example 1

[0043] A bag sorting machine, such as Figure 1 As shown, it includes a material receiving device 1, a material taking device 3, and a bundling device 4. The bundling device 4 is arranged on one side of the material receiving device 1, and the material taking device 3 is arranged above the bundling device 4. The material taking device 3 is used to clamp the material from the material receiving device and send it to the bundling device.

[0044] like Figure 2 The material receiving device 1 comprises an upper supporting rod device 11, a lower supporting rod device 12, a material blocking partition plate 13 and a bag sorting rod device 14. The upper supporting rod device 11 is horizontally installed on the frame parallel to the feeding direction of the bag making machine. The lower supporting rod device 12 is arranged below the upper supporting rod device 11. There is a certain space between the upper supporting rod device 11 and the lower supporting rod device 12 to accommodate products and for the material taking device 3 to telescopically take materials. The material blocking partition plate 13 is vertically arranged relative to the supporting rod device 11 and the lower supporting rod device 12 to limit the products on the upper supporting rod device 11 and the lower supporting rod device 12. Figure 2 In order to clearly show the structure between the material blocking partitions 13, the material blocking partitions on the opposite side are omitted.

[0045] like Figure 3-4 As shown, the upper support rod device 11 includes an upper support rod horizontal reset displacement device 111 , an upper support rod slide rail 112 , and an upper support rod unit 113 disposed on the upper support rod slide rail 112 .

[0046] The upper support rod horizontal reciprocating displacement device 111 is used to drive the upper support rod unit 113 to perform horizontal reciprocating motion, extending into the material receiving area (above the lower support rod) and exiting the material receiving area. The upper support rod slide rail 112 is installed on the upper support rod horizontal reciprocating displacement device 111 as a load, and the position of the upper support rod unit 113 on the upper support rod slide rail 112 is adjustable.

[0047] The upper support rod horizontal reciprocating displacement device 111 can be any conventional reciprocating linear motion mechanism such as a reciprocating cylinder, a hydraulic cylinder, an electric cylinder, a belt mechanism, a gear rack mechanism, etc. Figure 2-3 The synchronous belt linear module is used, including a drive motor, a rotating shaft, a synchronous pulley, a belt, a guide rail and a slider. The guide rail is horizontally installed on the frame parallel to the discharge direction of the bag making machine, the rotating shaft is installed at both ends of the guide rail through the bearing seat, the synchronous wheel is fixed on the rotating shaft, and the belt drives the slider to operate.

[0048] The upper support rod unit 113 includes an upper support rod 1131, an upper support rod fixing block 1132, an upper support rod pressure plate 1133 and a second spring plunger 1134. The upper support rod 1131 is mounted on the upper support rod fixing block 1132, and the upper support rod fixing block 1132 is connected to the upper support rod slide rail 112 in a sliding manner. An upper support rod pressure plate 1133 is also provided on the upper support rod fixing block 1132, a threaded hole is provided on the upper support rod pressure plate 1133, and the second spring plunger 1134 is installed on the upper support rod pressure plate 1133. A plurality of positioning grooves that cooperate with the second spring plunger 1134 are provided on the upper support rod slide rail 112. By controlling the depth of the second spring plunger 1134 being screwed into the positioning groove, the position adjustment and fixation of the upper support rod fixing block 1132 on the upper support rod slide rail 112 can be achieved.

[0049] As a preferred connection method, the upper support rod 1131 is detachably mounted on the upper support rod fixing block 1132. Figure 4 The upper support rod fixing block 1132 is provided with a socket for inserting the upper support rod, and the upper support rod 1131 is installed in the socket. In order to prevent the upper support rod 1131 from falling off from the upper support rod fixing block 1132, one end of the upper support rod is provided with a limiting protrusion.

[0050] The upper support rod fixing block 1132 is detachably connected to the upper support rod pressing plate 1133. In the accompanying drawings, the upper support rod pressing plate 1133 is bolted to one end of the upper support rod fixing block 1132, sandwiching the limiting protrusion of the upper support rod 1131 in the middle, and also enhancing the connection firmness between the upper support rod and the upper support rod fixing block 1132.

[0051] 3 to 5 or more insertion holes can be arranged in parallel on the upper support rod fixing block 1132, so as to realize the overall movement of several upper support rods.

[0052] like Figure 5 As shown, the lower support rod device 12 includes a lower support rod 121 and a lower support rod lifting device 122. The lower support rod 121 is arranged parallel to the upper support rod 1131, the upper surface of the lower support rod is the bearing surface of the product, and the lower support rod lifting device 122 is used to drive the lower support rod 121 to rise and fall.

[0053] As one of the preferred installation structures of the lower support rod 121, the lower support rod 121 is connected to the lower support rod lifting device 122 through a lower support rod mounting frame 123. The lower support rod mounting frame 123 includes a bracket 1231 and a bracket mounting plate 1232. The bracket mounting plate 1232 is fixedly arranged on the lower support rod lifting device, and the brackets 1231 are arranged in parallel on the bracket mounting plate 1232. The lower support rod 121 is fixedly arranged at the top of the bracket 1231.

[0054] As one of the preferred structures of the bracket, the bracket 1231 is rod-shaped, and each lower supporting rod 121 is supported by at least two rod-shaped brackets.

[0055] As one of the preferred structures of the bracket mounting plate 1232, the bracket mounting plate 1232 and the bracket 1231 are detachably connected. Figure 5 The structure is pluggable, a through hole is provided on the bracket mounting plate 1232, and the bracket is vertically inserted into the through hole. A baffle 1233 with a blind hole is fixedly provided at the bottom of the bracket mounting plate 232 at a position corresponding to the through hole, and the through hole on the bracket mounting plate 1232 is opposite to the blind hole on the baffle 1233, so that the bracket is more stable after being inserted.

[0056] The lower support rod lifting device 122 can be a pneumatic lifting mechanism, a cylinder lifting mechanism, a screw lifting mechanism, a gear rack lifting mechanism, or other lifting mechanisms. Figure 5 A screw lifting mechanism is adopted.

[0057] The material taking device 3 is arranged between the upper supporting rod 1231 and the lower supporting rod 121. The material taking device 3 includes a linear reciprocating motion mechanism and a clamping device 33 arranged on the linear reciprocating motion mechanism. The linear reciprocating motion mechanism drives the clamping device to enter the material receiving area above the lower supporting rod 21 from between the material blocking partitions 13, clamps the stacked products on the lower supporting rod 21 and transfers them to the next station, and finally places the products at the designated position. The clamping device 33 is used to clamp the product, and an existing clamping device, such as a finger cylinder, can be used.

[0058] The material blocking baffle 13 limits the position of the product from the upstream. The material blocking baffle 13 is set in the gap between the upper supporting rod 1131 and the lower supporting rod 121, and will not interfere with the reciprocating motion of the upper supporting plate 1131, nor will it interfere with the lifting and lowering of the lower supporting rod 121. The lowermost end of the material blocking baffle 13 is at the lowest position of the lower supporting rod 121, ensuring that the product is in a restrained state before being clamped.

[0059] like Figure 6 As shown, in order to facilitate the adjustment of the position of the blocking partition 13 and the distance between the blocking partitions 13, the blocking partition 13 is arranged on the slider of the partition slide rail 133 through the partition connecting rod 132, and the two ends of the partition slide rail 131 are connected to the frame. In order to enhance the installation stability of the blocking partition, a support rod 134 is also arranged on the frame to support the partition connecting rod 132.

[0060] The bag sorting machine is also provided with a bag sorting rod device 14. Figure 2 As shown, the bag sorting rod device 14 includes a bag sorting rod 141 and a bag sorting rod reciprocating motion mechanism. The bag sorting rod 141 is vertically arranged between the material blocking partition 13, and the lower end of the bag sorting rod 141 avoids interference with the material taking device. The bag sorting rod 141 limits and arranges the products so that the products are stacked on the upper supporting rod 1131 and the lower supporting rod 121, and when the upper supporting rod 1131 withdraws, the products temporarily received by the upper supporting rod 1131 fall smoothly onto the lower supporting rod 121.

[0061] The bag sorting rod reciprocating motion mechanism is used to drive the bag sorting rod 141 to reciprocate in the front and rear directions. The bag sorting rod reciprocating motion mechanism can be a reciprocating cylinder, a hydraulic cylinder, an electric cylinder, a belt mechanism, a gear rack mechanism, or any other conventional reciprocating linear motion mechanism.

[0062] Figure 7As shown, the strapping device 4 includes a strapping machine 41 and a product pressing device 42. The product pressing device 42 includes a product pressing rod 421 and a pressing rod lifting mechanism 422 for driving the product pressing rod to rise and fall. The pressing rod lifting mechanism 422 is arranged on both sides of the strapping machine 41, and the product pressing rod 421 is arranged on the moving part of the pressing rod lifting mechanism 422. The pressing rod lifting mechanism 422 can be a cylinder, a hydraulic cylinder, an electric cylinder, a linear motor, a gear rack transmission mechanism, a nut screw mechanism or a motor belt transmission mechanism. The pressing device is activated before strapping, and the stacked sheet materials are first pressed and then strapped. In particular, for materials that are relatively fluffy after stacking, such as middle-sealed bags, the strapping tightness is greatly improved.

[0063] When the bag making machine is working, the product enters between the material blocking baffles 13, and after the product is cut, it falls on the upper support rod 1131. The bag sorting rod 141 performs pulse motion to align it. After the upper support rod 131 receives the set number of materials and the lower support rod 21 is ready, the upper support rod 131 withdraws from the material receiving area, and the bag sorting rod 141 blocks the product so that it is transferred to the lower support rod 121. The lower support rod 121 gradually decreases as the number of received materials increases, so that the height of the last product is consistent with the discharge port of the bag making machine. After the number of received materials reaches the set value, the upper support rod 131 extends to temporarily receive the product, and the lower support rod 121 descends to the material taking position. The material taking device 3 drives the clamping claw 33 to enter the material receiving area. Between the left and right material blocking baffles, the clamping claw closes and clamps the product. The material taking device 3 drives the clamping claw device 33 to move out of the material receiving area and move to the strapping device for strapping. The lower support rod 121 rises to the material receiving position and waits for the next cycle.

[0064] When the bag sorting rod device 14 is working, first adjust the position of the blocking partition 13 and the distance between the blocking partitions according to the width and length of the sheet products. When receiving stacked sheet products, the width and length of the sheet products are limited by the blocking partition 13, and the bag sorting rod device 14 at the rear is pushed forward by pulses to sort the sheet products.

[0065] After the products are stacked, the clamping device 33 clamps the products from between the blocking partitions to ensure that the products are in a restrained state during the bag sorting and material taking process, thereby ensuring that the bag sorting process of different products is in an orderly state.

[0066] After the product is transferred from the upper support rod to the lower support rod and bagging is completed, it is grabbed by the material taking device and sent to the next process, eliminating the need for redundant transfer devices.

[0067] Example 2

[0068] The main difference from Example 1 is the structure of the linear reciprocating motion mechanism.

[0069] As a preference, under the premise of satisfying the travel, the structure of the linear reciprocating motion mechanism is as simple as possible, occupies as little space as possible, and is easy to install. Figure 8-10As shown, the material taking device includes a first reciprocating motion mechanism 31 , a second reciprocating motion mechanism 32 and a clamping claw device 33 .

[0070] The first reciprocating motion mechanism 31 includes a first-layer slide rail 311 , a second-layer slide rail 312 , a first-layer synchronous belt fixing block 313 , a second-layer synchronous belt fixing block 314 , a synchronous belt 315 , a rotating shaft 316 and a driving mechanism 317 .

[0071] The first slide rail 311 and the second slide rail 312 are arranged in parallel, and the two slide rails can be formed on the same material, or can be fixedly connected to form a double-layer slide rail by a connector, and the attached drawing uses a slide rail connecting plate 3120 for fixed connection. The first slide rail is slidably connected to the frame. Fig. 9 The slider and the slide rail are matched and connected. A first slider 318 is arranged on the first slide rail 311, and the first slider 318 is fixed on the frame through a mounting plate.

[0072] A rotating shaft 316 is fixedly arranged at both ends of the double-layer slide rail, and the rotating shaft is installed on the bearing seat. The synchronous belt 315 is installed on the rotating shaft 316 at both ends, and the driving mechanism 317 is used to drive the rotating shaft 316 to rotate. The rotating shaft on either side can be the driving side. The bearing seat and the driving mechanism 317 are fixedly connected to the first layer slide rail 311 and the second layer slide rail 312. The bearing seat and the driving mechanism 317 shown in the figure are installed on the slide rail connecting plate 3120. The driving mechanism 317 can be a DC motor, a drive motor, a servo motor, etc.

[0073] A first synchronous belt fixing block 313 and a second synchronous belt fixing block 314 are fixedly arranged at the bisection of the synchronous belt 315. The first synchronous belt fixing block 313 is also fixedly connected to the frame, and the second synchronous belt fixing block 314 is slidably connected to the second layer slide rail 312. Figure 8-10 The second synchronous belt fixing block 314 is fixedly connected to the second slider 319 , and the second slider 319 is slidably matched with the slide rail 312 , so that the second synchronous belt fixing block 314 is slidably matched with the second slide rail 312 .

[0074] like Figure 8-10 As shown, the second reciprocating motion mechanism 32 is arranged on the second synchronous belt fixing block 314, and a clamping device 33 is installed on the reciprocating motion component of the second reciprocating motion mechanism 32. The second reciprocating motion mechanism 32 can be various conventional reciprocating linear motion mechanisms such as a reciprocating cylinder, a hydraulic cylinder, an electric cylinder, a belt mechanism, a gear rack mechanism, etc. In order to facilitate installation, a shift sliding plate 321 can be provided, and the shift sliding plate 321 is fixedly connected to the second slider, and the second reciprocating motion mechanism 32 is arranged on the shift sliding plate 321. The second reciprocating motion mechanism 32 in the attached figure adopts a slider driven by a cylinder, and the cylinder and the slide rail are installed on the shift sliding plate 321, and the shift sliding plate 321 is fixedly set on the second slider 319.

[0075] The working process of the linear reciprocating motion mechanism: the left side of the observer facing the figure is the left side of the figure, and the right side is the right side of the figure. Fig.11 As shown, when the initial position is state 1, the first slider is at the left limit of the first slide rail, and the second slider is at the right limit of the second slide rail. Because the first synchronous belt fixing block clamps the displaced synchronous belt and is fixed on the mounting plate, the synchronous belt as a whole cannot rotate, and the driving motor causes the driving side shaft to rotate counterclockwise. Under the action of the counterclockwise rotation of the active side synchronous wheel, the distance between the active side synchronous wheel and the first synchronous belt fixing block decreases, and the distance between the passive side synchronous wheel and the second synchronous belt fixing block also decreases at the same speed, so that the first slide rail slides to the left in the first slider, and the second slider also slides to the left in the second slide rail, reaching the position of state 2; the driving motor causes the driving side shaft to rotate clockwise. Under the action of the clockwise rotation of the active side synchronous wheel, the distance between the active side synchronous wheel and the first synchronous belt fixing block increases, and the distance between the passive side synchronous wheel and the second synchronous belt fixing block also increases at the same speed, so that the first slide rail slides to the right in the first slider, and the second slider also slides to the right in the second slide rail, returning to the position of state 1.

[0076] Example 3

[0077] The main difference from the first embodiment is the structure of the clamping jaw device 33 .
