Description

Technical Field

[0001] This utility model relates to the field of packaging and conveying technology, and in particular to a conveyor line unpacking mechanism. Background Technology

[0002] At the end of the automated packaging line in a yeast production line, in order to meet the requirements of efficient and orderly automated palletizing, it is usually necessary to smoothly lay down the upright packaging bags (such as 10kg / 25kg / 50kg bags of yeast powder) that have been filled and sealed to a horizontal position. This process is called "inverting the bags".

[0003] Traditional bag-turning mechanisms typically employ a flip-type placement rack structure: after the conveyor line transports upright bags to the designated station, a placement rack (often a plate or grid type) with a receiving surface flips at a 90° or greater angle under the action of a drive mechanism (such as a cylinder or motor), laying the bags down from a vertical to a horizontal position. Once the placement rack has finished flipping and the bags are laid horizontally, the entire bottom surface (or most of the contact surface) of the bags is in direct contact with the plane of the placement rack. When it is necessary to subsequently transfer the bags horizontally from the placement rack to the palletizing area, the conveyor belt or pusher plate mainly relies on applying pushing or frictional forces to make the bags slide on the surface of the placement rack.

[0004] This sliding friction method not only requires a large driving force, but more importantly, during the sliding process, a large frictional resistance is generated between the packaging bag and the surface of the shelf (especially hard or rough surfaces). This is especially true for heavier packaging, which can easily cause the surface of the packaging bag (especially the printed layer or coating of composite woven bags) to be scratched, worn or even damaged, seriously affecting the appearance quality of the product and potentially compromising the sealing integrity of the packaging.

[0005] To address this, the present invention provides a conveyor line reversing mechanism. After reversing the packaging, the rotating roller slightly lifts the packaging bag, causing it to detach from direct sliding contact with the placement rack. Rolling replaces pulling and sliding, minimizing damage to the surface of the packaging bag and ensuring a smoother and more convenient transfer process. Utility Model Content

[0006] The purpose of this utility model is to solve the problems existing in the prior art by proposing a conveyor line repacking mechanism.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A conveyor line unloading mechanism includes a beam frame. Two sets of bridge frames are symmetrically arranged on the crossbeam of the beam frame. An L-shaped placement frame is rotatably installed at the end of the two sets of bridge frames. The placement frame is driven by a telescopic rod rotatably installed on the beam frame and can rotate 90° forward and backward. Several through slots are spaced along the width direction on the placement frame. A rotating roller corresponding to each through slot is rotatably installed on the back side of the placement frame. A push plate perpendicular to the rotating roller is provided on the side of the beam frame. The push plate is driven by a telescopic rod and can move horizontally back and forth.

[0009] Preferably, the bottom of the back side of the placement frame is provided with an inclined connecting plate, which is inclined in the direction away from the beam frame. Two sets of bearings are provided on both sides of the connecting plate, staggered vertically. The upper bearing is rotatably connected to the end of the bridge frame, and the lower bearing is rotatably connected to the extended end of the telescopic rod.

[0010] Preferably, the back side of the placement rack is provided with multiple sets of ribs, which are staggered between the slots, and the thickness of the ribs gradually decreases from the bottom of the placement rack upwards.

[0011] Preferably, the bottom support of the placement rack is provided with a notch corresponding to the cable tray.

[0012] Preferably, it also includes a bracket for placing the rear end of the frame when it is laid flat.

[0013] Preferably, the upper back of the placement frame is provided with a triangular reinforcing rib, and the bracket is provided with a slope that matches the reinforcing rib.

[0014] Preferably, the roller is designed to be separate from the placement frame.

[0015] Preferably, the rotating roller is a truncated cone that extends from top to bottom.

[0016] Preferably, the rotating roller is liftable.

[0017] Compared with the prior art, the present invention provides a conveyor line repacking mechanism, which has the following advantages:

[0018] 1. This utility model uses a rotating roller to lift the packaging bag, thus removing it from direct sliding contact with the placement frame. Rolling replaces pulling and sliding, thereby reducing the frictional contact surface during the transfer of the packaging bag, minimizing damage to the surface of the packaging bag, and ensuring a lighter and smoother transfer process.

[0026] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0027] Example 1: To mitigate the impact of slippage and friction on packaging bags after they are laid down, which can easily lead to wear and tear, this example provides a conveyor line reversing mechanism, including a beam frame 1. The beam frame 1 serves as the foundation of the conveyor line and is used for the installation of the conveyor belt. The conveyor belt is omitted in the attached drawings; only the end portion of the structure is shown. The beam frame 1 shown in the attached drawings includes longitudinal beams 102 (the direct mounting point for the conveyor belt) and crossbeams 101. Vertical beams are welded or bolted to the crossbeams 101, and the longitudinal beams 102 are bolted to the upper ends of the vertical beams, thus forming a frame structure.

[0028] Two sets of cable trays 2 are symmetrically arranged on the crossbeam 101 of the beam frame 1. Each set of cable trays 2 includes two U-shaped fastener frames 201 and a supporting beam 202. The two fastener frames 201 are welded and fixed to the crossbeam 101. The front upper and lower ends of the two fastener frames 201 extend to the left (for attachment). Figure 3(Taking the angle shown as an example), the first buckle frame 201 has a support beam 202 fixedly installed on its upper extension. The upper ends of the two support beams 202 in both sets of cable trays 2 are rotatably mounted with placement frames 4 via pre-drilled bolt holes. The rotatable connection is located at the lower back of the placement frame 4. The placement frame 4 is L-shaped, including a base and a flat surface. The lower extension of the second buckle frame 201 has a telescopic rod 7 rotatably installed. The extended end of the telescopic rod 7 is rotatably connected to the bottom back of the placement frame 4. The telescopic rod 7, the support beam 202, and the rotating parts of the placement frame 4 are offset, allowing the placement frame 4 to rotate 90° forward and backward by the telescopic rod 7.

[0029] The placement frame 4 has several through slots 5 spaced apart along its width, and a rotating roller 6 corresponding to each through slot 5 is rotatably installed on the back side of the placement frame 4.

[0030] A support frame (not shown in the appendix) is provided on the side of the beam frame 1. A telescopic rod 2 8 is fixedly installed on the support frame. The telescopic rod 2 8 is perpendicular to the rotating roller 6. A push plate 9 is fixed to the extended end of the telescopic rod 2 8. The push plate 9 is driven by the telescopic rod 2 8 and can move horizontally back and forth.

[0031] In this scheme, telescopic rod 7 and telescopic rod 8 can be any one of pneumatic rod, hydraulic rod, or electric telescopic rod.

[0032] In this design, a telescopic rod 203 is also provided on the lower extension of the mounting frame 201 of the supporting beam 202. The telescopic rod 203 is only used to assist in supporting the supporting beam 202 and to distribute the load. Alternatively, it can be a fixed support shaft.

[0033] Based on the above technical solution:

[0034] Initially, telescopic rod 7 is extended, placing the rack 4 vertically, with the base resting against or overlapping the surface of the conveyor line. At this point, the packaged yeast bags are conveyed along the conveyor line to the end, as shown by beam 1 in the diagram. After the bags move onto the rack 4, telescopic rod 7 retracts, causing the rack 4 to gradually flatten. Once flat, roller 6 slightly lifts the bags, reducing the contact area between the bags and the flat surface of the rack 4 or reducing the load friction on the flat surface. Then, telescopic rod 8 extends, pushing the bags away from the rack 4 via push plate 9 (for production, the flat position of rack 4 is connected to a palletizing conveyor line; push plate 9 directly pushes the bags onto the palletizing line for transport to the palletizing area).

[0035] The packaging bag is lifted by the rotating roller 6, which removes it from direct sliding contact with the placement frame 4. Rolling replaces pulling and sliding, thereby reducing the friction contact surface during the transfer of the packaging bag, minimizing damage to the surface of the packaging bag, and ensuring a lighter and smoother transfer process.

[0036] In a further embodiment of this solution, as described in Example 2, the bottom back of the placement frame 4 is provided with an inclined connecting plate 3. The connecting plate 3 is inclined in the direction away from the beam frame 1. Two sets of bearings are staggered on both sides of the connecting plate 3. The upper bearing is rotatably connected to the end of the support beam 202 of the bridge frame 2, and the lower bearing is rotatably connected to the extended end of the telescopic rod 7. This constitutes the required staggered design of the telescopic rod 7, the support beam 202, and the rotating parts of the placement frame 4, so as to achieve a 90° drive deflection of the placement frame 4 by extending and retracting the telescopic rod 7.

[0037] In a further embodiment of this solution, as described in Example 3, the back side of the placement rack 4 is provided with multiple sets of ribs 13, which are staggered between the slots 5. The multiple sets of ribs 13 enhance the overall assembly strength of the placement rack 4, preventing it from becoming hollow and weakened due to the presence of multiple slots 5, thus avoiding easy deformation.

[0038] Furthermore, the connecting plate 3 is positioned against the end of the rib plate 13 and is fixed by welding. This provides back support for the connecting plate 3, shares the torque of the connecting plate 3 when the telescopic rod 7 drives the placement frame 4 to deflect, and reduces the probability of deformation of the connecting plate 3.

[0039] The thickness of the rib 13 gradually decreases from the bottom of the placement rack 4 upwards. Generally, when the packaging bag is laid down, the load is concentrated at the base of the placement rack 4 and the root of the flat surface. Therefore, the structural strength required at this location is greater than that of other parts. Thus, the change in the thickness of the rib 13 meets both the strength support requirements of the placement rack 4 and the aesthetic requirements.

[0040] Preferably, ribs 13 are also provided on the bottom support to increase the strength of the bottom support.

[0041] In Example 4, a further embodiment of this solution, the connecting plate 3 serves as the connection base between the placement frame 4 and the cable tray 2 support beam 202. The rotating parts of the support beam 202 and the connecting plate 3 should not be too far from the back side of the placement frame 4 to avoid excessive distance from the drive shaft center, which would prolong the torque and make the root of the connecting plate 3 more prone to cracking. The connecting plate 3 should not be too long; therefore, the bottom support of the placement frame 4 is provided with multiple notches to allow space for the cable tray 2 support beam 202.

[0042] In a further embodiment of this solution, in order to make the placement frame 4 more stable after being laid flat, and to assist the tension of the telescopic rod 7 when it is laid flat, a bracket 10 is also provided. The structure of the bracket 10 is the same as the end structure of the beam frame 1. After the placement frame 4 is laid flat, the end of the placement frame 4 rests on the bracket 10 for auxiliary support and to reduce the load intensity of the telescopic rod 7 at this time.

[0043] In a further embodiment of this solution (Example 6), since the end of the placement frame 4 rests on the bracket 10, a reinforcing rib 11 is provided on the upper back side of the placement frame 4 to improve its resistance to deformation under stress. The reinforcing rib 11 is triangular, and the bracket 10 has a slope that matches the reinforcing rib 11. This increases the contact surface area and disperses the load on the placement point of the placement frame 4. Furthermore, it transforms the original planar vertical support force into a sloping support force, further dispersing the force towards the telescopic rod 7 and improving its auxiliary support effect.

[0044] The reinforcing rib 11 rests against the rib plate 13 to share the load.

[0045] In Example 7, a further embodiment of this solution, the rotating roller 6 and the placement frame 4 are integrally set, which increases the weight of the placement frame 4 and the driving load of the telescopic rod 7. Therefore, in order to reduce the load on the telescopic rod 7, in this embodiment, the rotating roller 6 and the placement frame 4 are designed separately.

[0046] An additional support frame (not shown in the attached diagram, but the structure is similar to the beam frame 1 after a 90° rotation on the screen) is installed at the bottom of the flat position of the placement rack 4. Bearing seats 12 are provided on the support surface of the support frame, and the two ends of the rotating roller 6 are embedded in the inner rings of the bearings within the bearing seats 12, thus achieving external rotational installation of the rotating roller 6. In this way, after the placement rack 4 is laid flat, the rotating roller 6 extends beyond the flat surface of the placement rack 4 through the through groove 5, which also enables the lifting of the packaging bag.

[0047] In Example 8, based on Example 7, since the rotating roller 6 is separately installed from the placement frame 4, when the placement frame 4 tends to lie flat, the side of the rotating roller 6 closest to the beam frame 1 contacts the packaging bag first. To avoid scratches on the packaging bag at this time (because the weight of the packaging bag will concentrate in this area when the placement frame 4 is tilted), the rotating roller 6 is designed as a truncated cone from top to bottom. That is, the closer it is to the beam frame 1, the smaller the diameter of the rotating roller 6 becomes, and the end of the rotating roller 6 closest to the beam frame 1 is completely submerged on the back side of the placement frame 4, but the other side still shows the through groove 5. In this way, the lifting function of the rotating roller 6 is not affected, and the packaging bag is not scratched.

[0048] In Example 9, a further embodiment of this solution, the rotating roller 6 is height-adjustable. Specifically, a telescopic rod three is provided. The telescopic rod three can be directly installed on the foundation, with its extended end connected to the support frame to raise and lower the entire support frame; alternatively, the telescopic rod three can be mounted on the support frame, with its extended end connected to the bearing seat 12, and the roller 6 can be raised and lowered via the bearing seat 12.

[0049] After the placement rack 4 is completely flat, the roller 6 is then raised to pass through the slot 5, and the packaging bag is then lifted up, which can also avoid damage.
