Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of non-fired brick machines, and particularly relates to a pallet lifting device for a finished brick conveying line. Background Art
[0002] As Figure 1 shown, the finished bricks are placed on a pallet. The pallet falls onto the finished brick conveying line through a lowering plate machine. The movable pitch on the conveying line cooperates with the pawls fixed thereon to push the pallet to move. The pitch is a rectangular frame structure. Two rollers are respectively arranged on the left and right sides of the pitch, and the rollers move in the side-mounted U-shaped track. The U-shaped track is fixed on the frame, and the openings of the U-shaped tracks on both sides of the frame are arranged oppositely. When the pitch moves forward, the pawl can push the pallet forward. When the pitch moves backward, the pawl will rotate to avoid when touching the bottom of the pallet, so as to continuously convey the pallet forward. However, when the pallet moves, it slides relative to the fixed pallet rail on the upper side of the frame, and the contact surface between the pallet and the pallet rail will wear. Long-term reciprocating movement will cause serious wear. Summary of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.
[0022] Embodiment of the present invention:
[0023] As Figures 2 - 5 shown, the pallet lifting device of the finished brick conveying line includes a frame 4. A support rail 41 is provided at the top of the frame 4, and the support rail 41 is used to support the pallet 2. The pallet 2 can place multiple finished bricks 1. A pitch 5 that reciprocates in the left-right direction is provided inside the frame 4. The pitch 5 is a rectangular frame spliced by steel pipes; the corresponding number of pitches 5 is set according to the length of the conveying line, Figure 2 only one pitch 5 is shown in the figure. Two pawls 3 are respectively provided on the left and right sides inside the pitch 5. The pawls 3 are hinged, and the pawls 3 can rotate within a certain angle. Limit blocks are respectively provided on the left and right sides of the pawls 3 along their hinge axes (the hinge axes are along the front-rear direction). The limit blocks are located below the pawls 3 to limit the maximum rotation angle of the pawls 3. A U-shaped track 42 is provided inside the frame 4 for the rollers on the pitch 5 to slide and cooperate. By using the side-mounted U-shaped track 42, not only a support surface is provided for the rollers, but also the rollers can be limited, ensuring the stability of the movement of the pitch 5. By using the pitch 5 and the pawls 3 thereon, the pallet 2 can be continuously conveyed from left to right. The above is the existing product structure, and the present invention mainly adds two lifting mechanisms.
[0024] Figure 3 As shown, a lifting mechanism is symmetrically provided on the front and rear sides of the frame 4. The lifting mechanism includes a fixed component and a movable component arranged up and down. The fixed component includes a guide rail 7 fixed on the frame 4. The guide rail 7 includes an upper guide rail 71 and a lower guide rail 72.
[0025] Figure 3 and 4 As shown, the movable component includes a multi-link mechanism and a push rod 6. The multi-link mechanism is arranged on the pitch 5. The multi-link mechanism includes a horizontally arranged support rod 82, a connecting rod 81, and a V-shaped rod 83. The support rod 82 can rise and fall, and is used to support the support plate 2 and lift it up.
[0026] One end of the connecting rod 81 is hinged on the pitch 5, and the other end is hinged to one end of the supporting rod 82, and the length direction of the supporting rod 82 is along the left-right direction. One end of the V-shaped rod 83 is hinged to the other end of the supporting rod 82, and the other end of the V-shaped rod 83 cooperates with the top rod 6, and the top of the V-shaped rod 83 is hinged on the pitch 5. Specifically, the connecting rod 81 and the V-shaped rod 83 are both located on the outside of the pitch 5, and the pawl 3 is located on the inside of the pitch 5.
[0027] A long slot 62 is provided on the upper part of the push rod 6. The long slot 62 can be through front and back, or can be set as a blind slot. The long slot 62 is set in the left and right direction. A pin is provided at the other end of the V-shaped rod 83. The pin is inserted into the long slot 62 and can move left and right therein, which can also be understood as a hinged relationship. A support frame 9 is fixed on the pitch 5. The support frame 9 has a guide portion 91. The push rod 6 is guided and assembled in the guide portion 91 in the up and down direction. The guide portion 91 preferably adopts an open arc groove, and a sleeve can also be used in other embodiments.
[0028] The bottom of the push rod 6 is rollingly arranged on the guide rail, and when the bottom of the push rod 6 moves from the low position section to the high position section, the support rod 82 can move upward and lift the support plate 2.
[0029] A roller 61 is provided at the bottom of the top rod 6, and the roller 61 is used for rolling cooperation with the above-mentioned guide rail.
[0030] The guide rail includes an upper guide rail 71 and a lower guide rail 72. The upper guide rail 71 includes an upper horizontal section 711. The left end of the upper horizontal section 711 is provided with a first inclined rail section 712. The first inclined rail section 712 is arranged to be inclined downward and abuts against the lower guide rail 72. The upper horizontal section 711 is a high-position section, that is, the relative position is a high point. The first inclined rail section 712 is hinged to the left end of the upper horizontal section 711. The first inclined rail section 712 can be flipped upward when subjected to force, such as Figure 5 shown.
[0031] The right end of the upper horizontal section 711 is provided with a second inclined rail section 713, which is inclined downward. A return notch is formed between the bottom end of the second inclined rail section 713 and the lower guide rail 72, for the roller 61 at the bottom of the top rod 6 to pass through.
[0032] The lower guide rail 72 includes a lower horizontal section 721 and a third inclined rail section 723. The third inclined rail section 723 is located at the left end of the lower horizontal section 721 and slopes upward. An auxiliary horizontal section 724 is provided at the left end of the third inclined rail section 723. The bottom end of the first inclined rail section 712 abuts against the junction of the third inclined rail section 723 and the auxiliary horizontal section 724. The auxiliary horizontal section 724 serves as the low position section, that is, the low point of the initial position.
[0033] A guiding section 722 is provided at the right end of the lower horizontal section 721. The guiding section 722 is inclined upward and is located on the right side of the return slot, facilitating the slow transition of the roller 61 to the lower rail.
[0034] Working principle of the pallet lifting device of the finished brick conveying line:
[0035] Figure 4 As shown in the figure, it is the initial state. The roller 61 is located on the auxiliary horizontal section 724 of the lower guide rail 72, and the upper side of the support rod 82 does not contact the lower side of the pallet 2. When the pitch 5 moves to the right, it drives the roller 61 to move to the first inclined rail section 712. Since the first inclined rail section 712 is inclined, the ejector rod 6 will move upward, driving the V-shaped rod 83 and the support rod 82 to act. The V-shaped rod 83 rotates upward around its hinge axis, and the support rod 82 moves upward. The upper side of the support rod 82 gradually rises above the upper side of the support rail 41 and gradually lifts the pallet 2, separating the pallet 2 from the support rail 41.
[0036] When the roller 61 moves to the upper horizontal section 711 of the upper guide rail 71, the pallet 2 is on the support rod 82 and moves to the right together with the pitch 5. When the roller 61 moves onto the second inclined rail section 713, the ejector rod 6 moves downward, causing the support rod 82 to slowly descend, and the pallet 2 begins to fall onto the support rail 41, completing the station transportation of the pallet 2. After the roller 61 moves to the end of the second inclined rail section 713, under its own gravity, it can enter the return slot and fall onto the guiding section 722 of the lower guide rail 72. At this time, the pitch 5 starts to move to the left, and the roller 61 moves on the lower horizontal section 721. Since the position of the roller 61 is relatively low, it avoids the support rod 82 being lifted again during the leftward movement of the pitch 5. After the roller 61 moves to the third inclined rail section 723, it starts to move upward obliquely and pushes open the first inclined rail section 712 ( Figure 5 as shown in the figure), returns to the auxiliary horizontal section 724 of the lower guide rail 72, and the first inclined rail section 712 resets by gravity, reconnecting the upper rail and the lower rail to prepare for the next reciprocating movement.
[0037] During the process of conveying the pallet 2, the pallet 2 can be lifted by the support rod 82 and separated from the support rail 41, thus avoiding the wear problem caused by the reciprocating sliding fit between the pallet 2 and the support rail 41.
[0038] In other embodiments, only the auxiliary horizontal section 724 and the upper guide rail 71 in the above-mentioned guide rail may be adopted. The upper guide rail 71 includes an upper horizontal section 711 and a first inclined rail section 712. The first inclined rail section 712 is at the left end of the upper horizontal section 711. In this embodiment, the first inclined rail section 712 may be fixedly connected to the left end of the upper horizontal section 711, replacing the hinge connection in the above-mentioned embodiment. During the rightward movement of the pitch 5, the principle is similar to that of the above-mentioned embodiment. To prevent the support rod 82 from being lifted again during the leftward movement of the pitch 5, the upper guide rail 71 is set to be movable up and down. A cylinder is used as the driving mechanism, and the cylinder can pull the upper guide rail 71 downward until the upper horizontal section 711 of the upper guide rail 71 is flush with the auxiliary horizontal section 724.
