Description

Technical Field

[0001] The utility model relates to the technical field of packaging bags, in particular to a material receiving device. Background Art

[0002] For sheet products, such as flat printed materials, packaging bags, paper, etc., after they are produced, they usually need to go through stacking, sorting, packaging and bundling processes. At present, there are the following ways to receive sheet products: the upper and lower receiving plates take turns to receive materials, the lower receiving plate receives the delivered 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 delivered 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 extends again, 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 at the bottom of the sheet products, which easily causes 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 easily causes the stacked sheet products to be scattered. In order to improve the above problems, there are literature reports that a gap is set on the output platform, and a transfer module is set. The transfer module can be raised and lowered in the gap of the output platform. The transfer module extends from the output platform to receive the sheet product on the receiving rod, and then descends to transfer the received sheet product to the output platform. The receiving rod is not pulled at the bottom of the sheet product, and the stacked sheet products do not fall, which reduces the risk of scratches on the sheet products and the risk of the sheet products falling and scattering. However, we noticed that the sheet products are always in an unrestrained state during the transfer and transportation between the upper and lower receiving plates. When stacked to a certain height, they are easy to tip over, especially for light, fluffy, and smooth-surfaced products. During the transfer process, the unrestrained sheet stacks are at greater risk of sliding and tipping over. Utility Model Content

The lower supporting rod device 2 is arranged below the upper supporting rod device 1. The space between the upper supporting rod device 1 and the lower supporting rod device 2 accommodates the product. The material blocking partition 3 is vertically arranged relative to the supporting rod device 1 and the lower supporting rod device 2 to limit the product on the upper supporting rod device 1 and the lower supporting rod device 2. Figure 1 In order to clearly show the structure between the material blocking partitions, the material blocking partition on the opposite side is omitted.

By controlling the depth of the first spring plunger 134 being rotated into the positioning groove, the position adjustment and fixation of the upper support rod fixing block 132 on the upper support rod slide rail 12 can be achieved.

[0043] As a preferred connection method, the upper support rod 131 is detachably mounted on the upper support rod fixing block 132. Figure 4 The upper support rod fixing block 132 is provided with a socket for inserting the upper support rod, and the upper support rod 131 is installed in the socket. In order to prevent the upper support rod 131 from falling off from the upper support rod fixing block 132, one end of the upper support rod is provided with a limiting protrusion.

[0044] The upper support rod fixing block 132 is detachably connected to the upper support rod pressing plate 133.

[0045] A number of 3 to 5 insertion holes can be arranged in parallel on the upper support rod fixing block 132, so that the overall movement of a number of upper support rods can be realized.

[0048] As one of the preferred structures of the bracket, the bracket 231 is rod-shaped, and each lower supporting rod 21 is supported by at least two rod-shaped brackets.

[0049] As one of the preferred structures of the bracket mounting plate 232, the bracket mounting plate 232 and the bracket 231 are detachably connected. Figure 4The structure is pluggable, a through hole is provided on the bracket mounting plate 232, and the bracket is vertically inserted into the through hole. A baffle 233 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 232 is opposite to the blind hole on the baffle 233, so that the bracket is more stable after being inserted.

[0050] The lower support rod lifting device 22 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.

[0051] The material picking device 3 is arranged between the upper support rod 231 and the lower support rod 21. The material picking device 3 includes a linear reciprocating motion mechanism and a clamping device arranged on the linear reciprocating motion mechanism. The linear reciprocating motion mechanism drives the clamping device to enter the material receiving area between the material blocking partitions, clamps the product on the lower support rod 21 and transfers it to the next workstation, and finally places the product at the designated position.

[0052] 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 6 As shown, the material taking device includes a first reciprocating motion mechanism 31 , a second reciprocating motion mechanism 32 and a clamping claw device 33 .

[0053] like Figure 6-7 As shown, 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 .

[0054] The first slide rail 311 and the second slide rail 312 are arranged in parallel. The two slide rails can be formed on the same piece of material, or can be fixedly connected to form a double-layer slide rail by a connecting piece. Figure 6 The first layer of slide rail 311 is connected with the frame in a sliding manner. Figure 6 The slider and the slide rail are matched and connected. The 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.

[0055] The two ends of the double-layer slide rail are fixedly provided with a rotating shaft 316, which is installed on the bearing seat, and the synchronous belt 315 is installed on the rotating shaft 316 at both ends. 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. Figure 6The bearing seat and driving mechanism 317 shown are mounted on the slide rail connecting plate 3120. The driving mechanism 317 can be a DC motor, a drive motor, a servo motor, etc.

[0056] 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 6-7 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 connected with the second layer of slide rail 312 .

[0057] like Figure 7-8 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 a reciprocating cylinder, a hydraulic cylinder, an electric cylinder, a belt mechanism, a gear rack mechanism, or any other conventional reciprocating linear motion mechanism. For ease of 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. Figure 8 The second reciprocating motion mechanism 32 adopts a slide block driven by a cylinder. The cylinder and the slide rail are installed on a shift sliding plate 321 , and the shift sliding plate 321 is fixedly arranged on the second slide block 319 .

[0058] The clamping device 33 is used to clamp the product, and an existing clamping device, such as a finger cylinder, can be used. In order to better clamp and transfer the product on the lower support rod, the structure of the clamping device in the embodiment is as follows Fig. 9 As shown, the clamping jaw device 33 includes a clamping jaw 331 , a clamping jaw supporting plate 332 and a clamping jaw lifting mechanism 333 . The clamping jaw 331 is arranged on the clamping jaw supporting plate 332 , and the clamping jaw lifting mechanism is used to realize the lifting and lowering of the clamping jaw supporting plate 332 .

[0059] The clamp 331 includes a clamp execution arm 3311, a clamp swing arm 3312, a clamp connection arm 3313 and a clamp driving mechanism 3314; a clamp bracket 334 is arranged on the clamp support plate 332, one end of the clamp swing arm 3312 is hinged to the clamp bracket 334, and the other end is connected to one end of the clamp connection arm 3313 through a rotating shaft 3316, and the other end of the clamp connection arm 3313 is connected to the middle part of the clamp execution arm 3311 through an eccentric shaft 3315, and the length of the clamp connection arm 3313 can be changed by adjusting the angle of the eccentric shaft, and the telescopic rod of the clamp driving mechanism 3314 is connected to the rotating shaft 3316 to drive the clamp to open and close. When the stroke of the clamp driving mechanism remains unchanged, the clamping and closing size of the material-retrieving clamp can be adjusted to achieve the best clamping force for grabbing products of different thicknesses.

[0060] The front end of the clamping jaw supporting plate 332 is in the shape of a fork, and is arranged opposite to the clamping jaw actuating arm 3311. The clamping jaw supporting plate 332 has a space for accommodating the lower supporting rod, and can be inserted into the bottom of the product from the gap of the lower supporting rod.

[0061] The clamping jaw driving mechanism 3314 can adopt a pneumatic cylinder, a hydraulic cylinder or an electric cylinder.

[0062] The clamping jaw lifting mechanism 333 is installed on the second reciprocating motion mechanism 32, and the clamping jaw lifting mechanism 333 can be a cylinder, a hydraulic cylinder, an electric cylinder, a gear rack transmission mechanism, a linear motor or a nut screw mechanism. Fig. 9 A slider lifting mechanism is adopted, the lifting slider 3331 and the lifting cylinder 3332 are installed on the clamp mounting plate 3333, the clamp mounting plate 3333 is fixedly set on the slider of the second reciprocating motion mechanism, the lifting rail 3334 is installed on the clamp support plate 332, and the piston rod of the lifting cylinder 3335 is connected to the clamp support plate.

[0063] A pressure plate bracket is provided at the end of the clamping jaw actuator arm 3311, and a clamping plate 3117 is provided on the pressure plate bracket. The clamping plate 3317 can swing within a certain range so that the clamping plate is parallel to the clamping jaw support plate at different heights, thereby better clamping the product. The clamping plate 3317 can be detachably mounted on the pressure plate bracket and can be quickly replaced to be suitable for products of different widths.

[0064] The clamping device 33 further includes a clamping push plate 335, which is disposed on the clamping support plate 332 below the clamping actuator arm 3311. The clamping actuator arm 3311 has a structure for avoiding interference.

[0065] The material blocking baffle 4 limits the product from the upstream. The material blocking baffle 4 is set in the gap between the upper supporting rod 131 and the lower supporting rod 21, and will not interfere with the reciprocating motion of the upper supporting plate 131, nor will it interfere with the lifting and lowering of the lower supporting rod 21. The lowermost end of the material blocking baffle 4 is at the lowest position reached by the lower supporting rod 21, ensuring that the product is in a restrained state before being clamped.

[0066] like Fig.10 As shown, in order to facilitate the adjustment of the position of the blocking partition and the distance between the blocking partitions, the blocking partition 4 is arranged on the slider of the partition slide rail 41 through the partition connecting rod 42, and the two ends of the partition slide rail 41 are connected to the frame. In order to enhance the installation stability of the blocking partition, a support rod 43 is also arranged on the frame to support the partition connecting rod 42.

[0067] The bag sorting rod device 5 includes a bag sorting rod 51 and a bag sorting rod reciprocating motion mechanism 52. The bag sorting rod 51 is vertically arranged between the material blocking partitions 4, and the lower end of the bag sorting rod 51 is higher than the material taking device to avoid interference with the material taking device. The bag sorting rod 51 limits the upstream products perpendicular to the conveying direction, so that the products are stacked on the upper supporting rod 131 and the lower supporting rod 21, and when the upper supporting rod 131 withdraws, the products temporarily received by the upper supporting rod 131 fall smoothly onto the lower supporting rod 21.

[0068] The bag sorting rod reciprocating motion mechanism 52 is used to drive the bag sorting rod 51 to reciprocate in the front and rear directions. The bag sorting rod reciprocating motion mechanism 52 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. Fig.11 The cylinder is used.

[0069] The bag sorting rod 51 can be detachably mounted on the frame, and the front and rear positions of the bag sorting rod 51 can be adjusted, and the position can be adjusted left and right according to the position of the material blocking partition 3. Fig.12 As shown, the bag sorting rod 51 is installed on the bag sorting rod slide rail 55, and the bag sorting rod slide rail 55 is installed on the bag sorting rod reciprocating motion mechanism 52. The bag sorting rod reciprocating motion mechanism 52 is installed on the bag sorting rod cross beam 56, and both ends of the bag sorting rod cross beam 56 are installed on parallel slide rails 57, and both ends of the bag sorting rod cross beam 56 are provided with sliders matching with the parallel slide rails.

[0070] To facilitate installation and adjustment, Fig.12 As shown, the bag sorting rod 51, the bag sorting rod fixing block 53, the bag sorting rod pressure plate 54 and the second spring plunger 58 are assembled into a bag sorting rod unit. The bag sorting rod fixing block 53 is connected to the bag sorting rod slide rail 55 in a sliding manner. The bag sorting rod 51 is installed on the bag sorting rod fixing block 53. The bag sorting rod pressure plate 54 is also fixedly arranged on the bag sorting rod fixing block 53. The bag sorting rod pressure plate 54 is provided with a threaded hole, and the second spring plunger 58 is installed on the bag sorting rod pressure plate 54. The bag sorting rod slide rail 55 is provided with a plurality of positioning grooves that cooperate with the second spring plunger. By controlling the depth of the second spring plunger 58 being rotated into the positioning groove, the position adjustment and fixation of the bag sorting rod fixing block 53 on the bag sorting rod slide rail 55 can be achieved.

[0071] Of course, there are many other ways to detachably install the bag sorting rod 51 on the frame, such as setting a mounting beam on the frame, setting a socket on the mounting beam, and the bag sorting rod is pluggable in the mounting hole.

[0072] 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.13 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.

[0073] When the bag making machine is working, the product enters between the material blocking partitions 4, and after the product is cut, it falls on the upper support rod 131. The bag sorting rod 51 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 51 blocks the product so that it is transferred to the lower support rod 21. The lower support rod 21 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 21 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 partitions, the clamping claw push plate 335 flattens the product, and 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 enter the next process. The lower support rod rises to the material receiving position and waits for the next cycle.

[0074] When the bag sorting rod device 5 is working, first adjust the position of the blocking partition 4 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 4, and the bag sorting rod device 5 at the rear is pushed forward by pulses to sort the sheet products.

[0075] After the products are stacked and stacked, the clamping device 33 clamps the products from between the left and right material 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.

[0076] 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.

[0077] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "connected" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0078] The embodiments described above are only descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
