Description

Technical Field

[0001] The utility model belongs to the field of bagged goods shaping equipment, in particular to a bagged goods shaping machine. Background Art

[0002] Currently, vertical warehouse conveyor lines are widely used in various warehouse applications. Due to their inherent advantages of reducing manual labor, providing precise positioning, and being fast and efficient, they significantly improve the efficiency of goods transported in and out of warehouses within smart warehouse management. On vertical warehouse conveyor lines, many goods are bagged, then placed on pallets and transported along the conveyor line. During the transportation of bagged goods, there is a risk of misalignment when operators stack the bags on the pallet, or the bags become loose and tilted during transport on the vertical warehouse conveyor line. These factors can cause the bagged goods to shift in shape or position on the pallet, hindering subsequent boxing operations. Therefore, when transporting bagged goods, they must first be shaped before being transported to the boxing location for boxing.

[0003] Existing shaping machines generally use cylinders to push the push plates horizontally, so that the push plates can shape the left and right sides of the bagged goods entering the shaping machine. Among them, the use of pneumatic sources requires an additional air source device, which will make the entire shaping machine structure complicated and increase the cost of building a vertical warehouse conveyor line. In addition, when using cylinder drive, the pushing distance and pushing force of the cylinder are difficult to control, which can easily cause the bagged goods in the shaping machine to either have an unclear shaping effect or excessive shaping, thereby damaging the goods and pallets. And when the cylinder pushes the push plates to shape the sides of the bag, the movement of the push plates on both sides is independent of each other, which will result in the need to control the movement of the two cylinders separately during the shaping process, so as to realize the two push plates to perform the shaping operation on the bagged goods. This operation can easily lead to inconsistent shaping forces of the push plates on both sides on the bagged goods, thereby affecting the shaping effect of the shaping machine. Utility Model Content

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] This embodiment provides a bagging shaping machine, such as Figure 1As shown, it includes a frame, a conveyor belt 2, a driving mechanism and two push plates 3. In this embodiment, the frame includes an upper frame 11, a lower frame 12, a left frame and a right frame. The upper frame 11, the lower frame 12, the left frame and the right frame are able to form a frame with a hollow structure. The conveyor belt 2 passes through the frame from one end of the frame and passes out along the other end of the frame. In this embodiment, the length direction of the lower frame 12 is the X-axis, the width direction of the lower frame 12 is the Z-axis, and the height direction of the lower frame 12 is the Y-axis. The conveyor belt 2 passes out along the Z-axis direction, and the conveyor belt 2 is located above the lower frame 12. A pallet is installed on the conveyor belt 2, and the pallet is used to place bagged goods 5. The conveyor belt 2 is used to transport the bagged goods 5 from the previous process into the frame, and perform shaping operations in the frame, and then transport the bagged goods 5 after shaping to the next process.

[0029] Please refer to Figure 2 and Figure 3 Two push plates 3 are vertically arranged along the Y-axis between the upper frame 11 and the lower frame 12, and are symmetrically positioned on either side of the conveyor belt 2 along the transport direction. Each push plate 3 is equipped with at least one pusher 31, which is slidably mounted on the frame and connected to the drive mechanism. In actual operation, when the bagged goods 5 on the pallet are transported into the frame via the conveyor belt 2, the conveyor belt 2 stops. The drive mechanism drives the push plates 3 toward the bagged goods 5 via the pushers 31, allowing the push plates 3 to perform shaping operations on both sides of the bagged goods 5, thereby completing the shaping of the bagged goods 5 on the pallet.

[0030] Please refer to Figures 3 to 5 The drive mechanism includes a driving member 41 and a chain assembly 42. The chain assembly 42 is mounted on the lower frame 12 and is located below the pusher 31. The chain assembly 42 includes two synchronous pulleys 421 and a synchronous belt that is connected to the two synchronous pulleys 421. The two synchronous pulleys 421 are arranged parallel to the X-axis and are located on both sides of the conveyor belt 2. The driving member 41 is connected to one of the synchronous pulleys 421. In the X-axis direction, the two synchronous pulleys 421 divide the synchronous belt into a connecting section 1 422 and a connecting section 2 423. The synchronous belt is provided with a connecting block 1 424 and a connecting block 2 425. The connecting block 1 424 is hingedly mounted on the connecting section 1 422, and the connecting block 2 425 is hingedly mounted on the connecting section 2 423. The connecting block 1 424 and the connecting block 2 425 are located on both sides of the conveyor belt 2.

[0031] In this embodiment, the driving member 41 may be a motor, which is installed on the lower frame 12 .

[0032] In this embodiment, please refer to Figure 5, connecting block 1 424 is disposed on the left side of the conveyor belt 2, and connecting block 2 425 is disposed on the right side of the conveyor belt 2. On the left side of the conveyor belt 2, connecting block 1 424 is fixedly connected to the pushing member 31 on the push plate 3 located on the left side of the conveyor belt 2. On the right side of the conveyor belt 2, connecting block 2 425 is fixedly connected to the pushing member 31 on the push plate 3 located on the right side of the conveyor belt 2. When the driving member 41 is connected to one of the synchronous pulleys 1 421 and drives one of the synchronous pulleys 1 421 to rotate, the synchronous belt drives connecting block 1 424 and connecting block 2 425 to rotate. When synchronous pulley 1 421 rotates clockwise, connecting block 1 424 and connecting block 2 425 move away from each other. At this time, the distance between connecting block 1 424 and connecting block 2 425 increases. Under the joint action of connecting block 1 424 and connecting block 2 425, the distance between the two push plates 3 also increases. When synchronous pulley 1 421 rotates counterclockwise, connecting block 1 424 and connecting block 2 425 move relative to each other. At this point, the distance between connecting block 1 424 and connecting block 2 425 becomes increasingly smaller. Under the combined action of connecting block 1 424 and connecting block 2 425, the distance between the two push plates 3 also becomes increasingly smaller. In actual operation, if it is necessary to perform a shaping operation on the bagged goods 5, the driver 41 is simply controlled to drive synchronous pulley 1 421 to rotate counterclockwise. The two push plates 3 will move toward the conveyor belt 2, thereby shaping both sides of the bagged goods 5 on the pallet within the frame so that the width of the goods to be loaded after the shaping operation meets the storage requirements. Once the shaping is complete, the driver 41 is controlled to drive synchronous pulley 1 421 to rotate clockwise. The two push plates 3 will move away from the conveyor belt 2. At this point, the two push plates 3 have no force on the bagged goods 5 on the pallet. The conveyor belt 2 can then be started, allowing the shaped bagged goods 5 to be transported to the next process.

[0033] In this embodiment, by providing a connecting block 1 424 and a connecting block 2 425 on the synchronous belt, and limiting the positions of the connecting block 1 424 and the connecting block 2 425, when the synchronous belt rotates, the connecting block 1 424 and the connecting block 2 425 can synchronously drive the two push plates 3 to move, so that the movement of the two push plates 3 can be synchronized relative to each other or move away from each other, thereby achieving synchronous control of the movement of the two push plates 3 by a single driving source, greatly simplifying the structure of the entire shaping machine and reducing the manufacturing cost of the entire shaping machine. In addition, in the prior art, two cylinders are used to drive the push plates 3 to level the two sides of the bagged goods 5, which easily leads to inconsistent forces exerted by the two push plates 3 on the two sides of the bagged goods 5, resulting in inconsistent shaping effects on the two sides of the bagged goods 5 due to uneven force. In the present invention, the two push plates 3 are synchronously controlled by the same driving source, so that the two push plates 3 exert the same force on both sides of the bagged goods 5, so that the shaping effects of the surfaces on the left and right sides of the bagged goods 5 after shaping are basically consistent, thereby improving the shaping effect of the push plates 3 when shaping the bagged goods 5.

[0034] It will be appreciated that during this shaping process, the frame may also be equipped with a photoelectric detection device that can be used to provide feedback to the control system when the conveyor belt 2 passes between the two push plates 3, which then controls the conveyor belt 2 to stop. This device may include two limit photoelectric sensors and a limit contact switch. One limit photoelectric sensor is located at a position where the push plates 3 are away from the conveyor belt 2. When the push plates 3 are at this limit photoelectric sensor, the distance between the two push plates 3 is at its maximum. At this point, the limit photoelectric sensor transmits the position of the push plates 3 to the control system, which controls the drive member 41 to stop. The other limit photoelectric sensor is located at a position where the push plates 3 are closer to the conveyor belt 2. When the push plates 3 are at this limit photoelectric sensor position, the distance between the two push plates 3 is at its minimum. This limit photoelectric sensor transmits the position of the push plates 3 to the control system, which controls the drive member 41 to stop. In this manner, the two push plates 3 are used to shape the bagged goods on the conveyor belt 2. The limit contact switch is designed to control the drive member 41 to stop after the push plates 41 have moved to a specified position if either limit photoelectric sensor is damaged. It is understood that the photoelectric detection device is a common device in the prior art, and therefore its principle will not be described in detail in this application. When shaping is completed (i.e., the photoelectric detection device detects that the width of the bagged goods 5 after shaping is less than a preset value), the control system can control the drive member 41 to drive the synchronous pulley to rotate clockwise until the push plate 3 is away from the bagged goods 5 and the bagged goods 5 is transported by the conveyor belt 2. The push plate 3 can stop moving without interfering with the bagged goods 5. The control system then activates the drive source connected to the conveyor belt 2, allowing the conveyor belt 2 to transport the shaped bagged goods 5 to the next process.

[0035] In this embodiment, please refer to Figure 5and Figure 6 Chain assembly 1 42 may also include a second synchronous pulley 426 and two guide pulleys 427. In this case, the drive member 41 is connected to a second synchronous pulley 426, instead of being connected to the first synchronous pulley 421 as described above. The provision of the second synchronous pulley 426 and two guide pulleys 427 can further improve the stability of the entire chain assembly 1 42 during movement.

[0036] Please refer to Figure 5 and Figure 6 , a mounting plate 121 and two mounting plates 122 are installed on the lower frame 12. The mounting plate 121 is located directly below the conveyor belt 2, and the two mounting plates 122 are symmetrically arranged with respect to the mounting plate 121. The synchronous pulley 426 and the two guide wheels 427 are both installed on the mounting plate 122. Specifically, along the X-axis direction, the synchronous pulley 426 is located above the two guide wheels 427, and the two guide wheels 427 are symmetrically arranged on both sides of the synchronous pulley 426. The guide wheel 427 can not only adjust the direction of the synchronous belt, but also adjust the tightness of the synchronous belt. Specifically, in this embodiment, the guide wheel 427 is detachably mounted on the mounting plate 122. The detachable mounting method facilitates the adjustment of the position of the guide wheel 427, thereby achieving the purpose of adjusting the tightness of the synchronous belt. One of the synchronous pulleys 421 is installed on one of the mounting plates 122, and the other synchronous pulley 426 is installed on the other mounting plate 122. The two synchronous pulleys 421 are also symmetrically arranged with respect to the synchronous pulley 426 in the X-axis direction.

[0037] Please refer to Figure 5 and Figure 6 A horizontally arranged guide rail 123 is installed between the mounting plate 121 and the mounting plate 2 122. The guide rail 123 is used to limit and guide the connecting section 122 between the guide wheel 427 and the synchronous pulley 1 421, so that the connecting section 122 between the guide wheel 427 and the synchronous pulley 1 421 always keeps moving along the X-axis direction, thereby ensuring the stability of the push plate 3 during the movement, so that when the push plate 3 levels the two sides of the bagged goods 5, the push plate 3 can contact the bagged goods 5 at all places, thereby improving the shaping effect of the push plate 3 on the bagged goods 5.

[0038] Please refer to Figure 5 and Figure 6A horizontally arranged guide rail 124 is installed between the two mounting plates 122. The guide rail 124 is used to guide and limit the connecting section 423 between the two mounting plates 122, so that the connecting section 423 located between the two synchronous pulleys 421 always keeps moving along the X-axis direction, and cooperates with the guide rail 123 to further improve the stability of the push plate 3 during the movement, thereby improving the shaping effect of the push plate 3 on the bagged goods 5.

[0039] In this embodiment, please refer to Figure 2 、 Figure 3 as well as Figure 8 The push plate 3 is provided with two pushers 31, which are symmetrically arranged along the Z-axis. On one push plate 3, one pusher 31 has one end connected to the connecting segment 1 422 of the chain assembly 1 42, and the other end connected to the push plate 3. The other pusher 31 has one end connected to the connecting segment 1 422 of the chain assembly 2 43, and the other end connected to the push plate 3. On the other push plate 3, one pusher 31 has one end connected to the connecting segment 2 423 of the chain assembly 1 42, and the other end connected to the push plate 3. The other pusher 31 has one end connected to the connecting segment 2 423 of the chain assembly 2 43. By arranging two pushing members 31 on each push plate 3, and the connection between one pushing member 31 and the push plate 3 is close to the upper frame 11, and the connection between the other pushing member 31 and the push plate 3 is close to the lower frame 12, when the push plate 3 is driven by the driving member 41, the chain component 1 42 and the chain component 2 43 to shape the bagged goods 5, the push plate 3 can generate a force on the bagged goods 5 from the top and bottom, so that the push plate 3 can well level the side of the bagged goods 5, thereby improving the shaping effect of the push plate 3 on the bagged goods 5.

[0040] Please refer to Figure 3The pusher 31 includes a sliding plate 311 and a connecting rod 312. The lower end of the sliding plate 311 is slidably mounted on the second mounting plate 122. One end of the connecting rod 312 is connected to the upper end of the sliding plate 311, and the other end of the connecting rod 312 is connected to the pusher 3. In this embodiment, a slide rail is mounted on the second mounting plate 122. The lower end of the sliding plate 311 is provided with a groove that matches the slide rail. The slide rail groove is used to install the sliding plate 311 on the second mounting plate 122. The connecting rod 312 includes a first rod body, two second rod bodies, and at least two third rod bodies. The second rod bodies are arranged along the Z axis, and the two second rod bodies are symmetrically mounted on the second mounting plate 122. The first rod body is arranged along the Y axis. One end of the first rod body is connected to one of the second rod bodies, and the other end of the second rod body is connected to the other second rod body. The end connected to the second rod body is the end away from the second mounting plate 122. The third rod body is arranged along the X axis and is located at both ends of the first rod body. One end of the rod body 3 is connected to the rod body 1, and the other end of the rod body 3 is connected to the push plate 3. By providing two rod bodies 3, the push plate 3 can be improved so that the force applied to each part of the push plate 3 is more uniform when it contacts the bagged goods 5, thereby improving the shaping effect of the push plate 3 on the side of the bagged goods 5.

[0041] At least one pair of limiting plates is installed on the second mounting plate 122 , and the sliding plate 311 is located between the pair of limiting plates. The limiting plates are used to limit the movement of the sliding plate 311 on the second mounting plate 122 .

[0042] Please refer to Figure 7 and Figure 8 The drive mechanism may further include a chain assembly 2 43 and a transmission shaft 44. The structure of the chain assembly 2 43 is the same as that of the chain assembly 1 42. The chain assembly 2 43 is mounted on the upper frame 11, and the chain assembly 2 43 and the chain assembly 1 42 are mirror images of each other about the perpendicular midplane between the upper frame 11 and the lower frame 12. The transmission shaft 44 is disposed between the upper frame 11 and the lower frame 12 along the Z-axis direction. One end of the transmission shaft 44 is connected to the synchronous pulley 1 421 of the chain assembly 1 42, and the other end of the transmission shaft 44 is connected to the synchronous pulley 1 421 of the chain assembly 2 43. The transmission shaft 44 is used to transmit the power generated by the driving member 41 to the chain assembly 2 43 through the chain assembly 1 42, so that the chain assembly 2 43 and the chain assembly 1 42 move synchronously. In this embodiment, by providing a chain assembly 2 43 and arranging it on the upper frame 11, a force can be generated on the push plate 3 near the upper frame 11 through the push member 31, and then the chain assembly 1 42 at the lower frame 12 pushes the push member 31 connected to it, so that when the push plate 3 shapes the bagged goods 5, the force on each part of the push plate 3 is relatively uniform, so that the side of the bagged goods 5 after shaping is relatively flat, thereby improving the shaping effect of the push plate 3 on the bagged goods 5.

[0043] In this embodiment, the transmission shaft 44 can be a segmented transmission shaft 44, comprising a first transmission shaft, a second transmission shaft, and a coupling. One end of the coupling is connected to the first transmission shaft, and the other end is connected to the second transmission shaft. The end of the first transmission shaft remote from the coupling is connected to the first synchronous pulley 421 of the first chain assembly 42, while the end of the second transmission shaft remote from the coupling is connected to the first synchronous pulley 421 of the second chain assembly 43. By configuring the transmission shaft 44 as a segmented transmission shaft 44, it can effectively transmit the power generated by the driving member 41 from bottom to top, achieving synchronous movement of the first chain assembly 42 and the second chain assembly 43 through a single driving member 41, thus simplifying the structure of the entire drive mechanism. In addition, the coupling provides overload protection during the transmission process. For example, if a problem occurs in the upper chain assembly 43, the coupling can buffer the gap between the first transmission shaft and the second transmission shaft, minimizing the impact on the first chain assembly 42, thereby reducing subsequent maintenance costs. Furthermore, providing a coupling can also improve the rigidity of the entire transmission shaft 44 and reduce force loss.

[0044] It is understandable that the bagging shaping machine of the present invention can be placed on different types of conveyors, such as chain conveyors, roller conveyors, etc., and can also use pallets and bagged goods of different widths.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
