Description

Technical Field

[0001] The utility model belongs to the technical field of packaging equipment, in particular to a top and bottom cover fastening machine. Background Art

[0002] At present, in the field of meat slaughtering and processing, slaughtering production lines are becoming increasingly large-scale and automated. However, the top and bottom covers are currently all fastened manually. Specifically, the lower box body containing the materials moves on the conveyor line, and the top and bottom covers of the corresponding models are manually taken and fastened onto the lower box body to complete the fastening.

[0003] Therefore, this method relies entirely on manual operation, which is not only inefficient but also labor-intensive. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a top and bottom cover snapping machine to solve the above-mentioned problems.

[0005] In order to achieve the above-mentioned purpose, the utility model discloses a lid-covering machine for top and bottom lids, comprising:

[0006] A conveyor line is used to transport the lower box containing materials, and a blocking mechanism is provided on the conveyor line;

[0007] The blocking mechanism is used to block the movement of the lower box and send a signal to the lifting mechanism;

[0008] Lifting mechanism, used to drive the front and rear positioning guide mechanisms and the left and right positioning guide mechanisms to rise and fall;

[0009] Front and rear positioning guide mechanism, used to clamp the lower box in the front and rear directions;

[0010] Left and right positioning guide mechanisms are used to clamp the lower box in the left and right directions;

[0011] The carton opening and cover buckling mechanism is used to unfold the upper cover of the carton and buckle the upper cover of the carton onto the lower box body.

[0012] Compared with the prior art, the present application has the following effects: first, the lower box body filled with materials moves on the conveyor line. When the materials touch the blocking mechanism, the blocking mechanism blocks the movement of the lower box body and sends a signal to the lifting mechanism; then, the lifting mechanism rises and drives the front and rear positioning guide mechanisms and the left and right positioning guide mechanisms to rise; then, the front and rear positioning guide mechanisms and the left and right positioning guide mechanisms clamp the front and rear and left and right directions of the lower box body respectively; finally, the box opening and cover buckling mechanism unfolds the upper cover of the carton and buckles the upper cover of the carton on the lower box body.

[0013] Therefore, the present application realizes the automatic closing of the top and bottom covers through automated equipment, and the entire process does not require human intervention, which not only reduces the workload of operators but also improves work efficiency.

[0014] Furthermore, the conveyor line is a roller conveyor line.

[0015] Furthermore, the blocking mechanism is a blocking cylinder, and the blocking cylinder is arranged on both sides of the roller conveyor line.

[0016] Furthermore, the lifting mechanism is a lifting cylinder.

[0017] Furthermore, the front and rear positioning guide mechanism and the left and right positioning guide mechanism both include a clamping cylinder, a clamping arm and a synchronization mechanism. The clamping cylinder is connected to the clamping arm through the synchronization mechanism to drive the clamping arm to synchronously clamp or release the lower box left and right, front and back when the clamping cylinder is extended or retracted.

[0018] Furthermore, the end of the clamp arm is in the shape of a bent sheet metal, and is inclined inward from top to bottom, so that the closer the lower box is to the upper side, the greater the degree of compression it is subjected to.

[0019] Furthermore, the box opening and cover-closing mechanism includes a material dividing device and a cover-closing device connected to each other, the material dividing device is used to divide multiple carton covers stacked up and down in the material bin into single carton covers, and the cover-closing device is used to cover the single carton cover onto the lower box body.

[0020] Furthermore, the material dividing device includes two groups of material dividing cylinders stacked up one above the other, with partitions fixed on the material dividing cylinders, and the distance between the upper and lower partitions is the stacking height of a single carton cover, so that when the material dividing cylinders on the upper layer are retracted and the material dividing cylinders on the lower layer are extended, the carton covers in the hopper are moved down as a whole by the stacking height of the carton covers, so that a single carton cover can fall between the partitions; conversely, when the material dividing cylinders on the upper layer are extended and the material dividing cylinders on the lower layer are retracted, the carton covers between the partitions automatically fall onto the cover-fastening device.

[0021] Furthermore, the cover-closing device includes an opening cylinder and a cover-closing cylinder. The opening cylinder is hinged to the cover-closing cylinder through a hinge seat. The opening cylinder is used to receive the carton cover that falls between the partitions, and the cover-closing cylinder is used to drive the opening cylinder to rotate, thereby completing the opening and closing of the carton cover.

[0022] Furthermore, the telescopic end of the cover-closing cylinder is connected to a synchronization plate for making the cover-closing cylinders on both sides telescope synchronously, and the synchronization plate is connected to the hinge seat; the telescopic end of the unpacking cylinder is connected to one end of a spring, and the other end of the spring is connected to the synchronization plate, and the spring is used to keep the unpacking cylinder in a horizontal state when it is not working.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figure 1-2 As shown, the utility model discloses a top and bottom cover capping machine, comprising:

[0033] The conveyor line 1 is used to transport the lower box containing materials, and a blocking mechanism 2 is provided on the conveyor line 1;

[0034] Blocking mechanism 2, used to block the movement of the lower box and send a signal to the lifting mechanism 3;

[0035] The lifting mechanism 3 is used to drive the front and rear positioning guide mechanism 4 and the left and right positioning guide mechanism 5 to rise and fall;

[0036] Front and rear positioning guide mechanism 4, used for clamping the lower box in the front and rear directions;

[0037] Left and right positioning guide mechanisms 5, used to clamp the lower box in the left and right directions;

[0038] The box opening and cover buckling mechanism 6 is used to unfold the upper cover of the carton and buckle the upper cover of the carton onto the lower box body.

[0039] Compared with the prior art, the present application has the following effects: first, the lower box body filled with materials moves on the conveyor line 1. When the materials touch the blocking mechanism 2, the blocking mechanism 2 blocks the movement of the lower box body and sends a signal to the lifting mechanism 3; then, the lifting mechanism 3 rises to drive the front and rear positioning guide mechanisms 4 and the left and right positioning guide mechanisms 5 to rise; then, the front and rear positioning guide mechanisms 4 and the left and right positioning guide mechanisms 5 clamp the front and rear and left and right directions of the lower box body respectively; finally, the box opening and cover buckling mechanism 6 unfolds the upper cover of the carton and buckles the upper cover of the carton on the lower box body.

[0040] Therefore, the present application realizes the automatic closing of the top and bottom covers through automated equipment, and the entire process does not require human intervention, which not only reduces the workload of operators but also improves work efficiency.

[0041] Continuing with the above embodiment, more specifically, the conveyor line 1 is a roller conveyor line, and in other embodiments it may also be a belt conveyor line.

[0042] Continuing with the above embodiment, more specifically, the blocking mechanism 2 is a blocking cylinder, which is arranged on both sides of the roller conveyor line.

[0043] In the first embodiment, there can be one blocking cylinder. Under normal conditions, the blocking cylinder is in an extended state. When the roller conveyor line drives the lower box to touch the blocking cylinder, the blocking cylinder prevents the lower box from moving, and sends a material arrival signal to the control system of the equipment through a sensor. The control system controls the roller conveyor line to stop rotating; at the same time, it controls the lifting mechanism 3 to rise, and the front and rear positioning guide mechanisms 4, the left and right positioning guide mechanisms 5, and the box opening and lid buckling mechanism 6 to work according to the set program; after the lid is buckled, the box opening and lid buckling mechanism 6 sends a signal to the control system, and the control system controls the lifting mechanism 3, the front and rear positioning guide mechanisms 4, the left and right positioning guide mechanisms 5, and the box opening and lid buckling mechanism 6 to reset, and the blocking cylinder to retract and the roller conveyor line to work, thereby conveying the lower box to the specified position. Among them, the control system is a PLC controller, which is a common control device in the mechanical field, and the specific working principle will not be repeated here.

[0044] In the second embodiment, there can be two blocking cylinders, which are respectively arranged on both sides of the roller conveyor line. Under normal conditions, according to the movement direction of the roller conveyor line, the blocking cylinder at the front end is in a retracted state, and the blocking cylinder at the rear end is in an extended state. When the roller conveyor line drives the lower box to touch the rear end blocking cylinder, the rear end blocking cylinder prevents the lower box from moving, and the front end blocking cylinder extends to block the lower box at the rear end of the roller conveyor line from entering the cover buckle area. At this time, the roller conveyor line can stop working or not. If it does not stop working, the material located in the cover buckle area is blocked between the two blocking cylinders, and the lower box at the rear end of the roller conveyor line cannot enter the cover buckle area because it is blocked by the front end blocking cylinder. The rear end blocking cylinder is used to prevent the lower box located in the cover buckle area from leaving the cover buckle area. In this way, the roller conveyor line does not need to be shut down frequently, thereby extending the service life of components such as motors used in the roller conveyor line.

[0045] Therefore, the second embodiment can achieve the purpose of fastening the cover without stopping the roller conveyor line. The specific process of fastening the cover is the same as that of the first embodiment and will not be described again. It should be noted that when the blocking cylinder is in the extended state, it has a guiding effect on the lower box body, which is more conducive to fastening the carton cover to the lower box body.

[0046] Continuing with the above embodiment, more specifically, the lifting mechanism 3 is a lifting cylinder. In other embodiments, it can also be a hydraulic cylinder, an electric cylinder or other similar retractable products.

[0047] Following the above embodiment, more specifically, Figure 3 As shown, the front and rear positioning guide mechanism 4 and the left and right positioning guide mechanism 5 each include a clamping cylinder 7, a clamping arm 8, and a synchronization mechanism 9. The clamping cylinder 7 is connected to the clamping arm 8 via the synchronization mechanism 9. When the clamping cylinder 7 is extended or retracted, the clamping arm 8 is driven to synchronously clamp or release the lower box left and right, front and back. The synchronization mechanism 9 is a common structure in the prior art and will not be described in detail. The left and right, front and back clamping arms 8 are respectively slidably connected to the synchronization mechanism 9 on both sides. When the clamping cylinder 7 drives the clamping arm 8 on either side to move, the clamping arm 8 on the other side will also move synchronously toward each other, thereby achieving the goal that when the lower box is tightened, the lower box will be in the center position of the entire positioning mechanism.

[0048] Continuing with the above embodiment, more specifically, the distal end of the clamp arm 8 is formed of a bent sheet metal and tilted inward from top to bottom, such that the lower box is squeezed more toward the upper side. After the lower box is clamped, the lower box is squeezed, with the degree of squeezing increasing toward the upper side, thereby forming a shape that is smaller at the top and larger at the bottom for easier fastening. This facilitates fastening and serves as a guide for fastening the carton cover.

[0049] In summary, the front and rear positioning guide mechanisms 4 and the left and right positioning guide mechanisms 5 complete the positioning, fixing and guiding functions of the lower box at one time.

[0050] Continuing with the above embodiment, more specifically, the box opening and cover closing mechanism 6 includes a material dividing device and a cover closing device that are interconnected. The material dividing device is used to divide multiple carton covers stacked up and down in the material bin into single carton covers, and the cover closing device is used to close the single carton cover onto the lower box body.

[0051] Continuing with the above embodiment, more specifically, the material dividing device includes two groups of material dividing cylinders 10 stacked up one above the other, with partitions 11 fixed on the material dividing cylinders 10, and the distance between the upper and lower partitions 11 is the stacking height of a single carton cover, so that when the upper material dividing cylinder 10 is retracted and the lower material dividing cylinder 10 is extended, the carton covers in the hopper are moved down as a whole by the stacking height of the carton covers, so that a single carton cover can fall between the partitions 11; conversely, when the upper material dividing cylinder 10 is extended and the lower material dividing cylinder 10 is retracted, the carton covers between the partitions 11 automatically fall onto the cover-fastening device.

[0052] Further, such as Figure 4 、 Figure 5 As shown, the cover-closing device includes an opening cylinder 12 and a cover-closing cylinder 13. The opening cylinder 12 is hinged to the cover-closing cylinder 13 through a hinge seat 14. The opening cylinder 12 is used to receive the carton cover that falls between the partitions 11, and the cover-closing cylinder 13 is used to drive the opening cylinder 12 to rotate, thereby completing the opening and closing of the carton cover.

[0053] More specifically, the telescopic end of the lid-closing cylinder 13 is connected to a synchronizing plate 15, which is connected to a hinged seat 14, for synchronously extending and retracting the lid-closing cylinders 13 on both sides. The telescopic end of the box-opening cylinder 12 is connected to one end of a spring, the other end of which is connected to the synchronizing plate 15. The spring ensures that the box-opening cylinder 12 remains horizontal when not in operation. Furthermore, the box-opening cylinder 12 is connected to a guide rod 16, which is used to receive and pull open the top cover of the carton. Similar to a mechanical gripper, the guide rod 16 can latch onto the lower edge of the top cover of the carton and prop it open to complete the box-opening operation.

[0054] During operation, the upper cover of the carton falls onto the guide rod 16. At this time, the cover-fastening cylinder 13 is in a retracted state and the box-opening cylinder 12 is in an extended state; then the cover-opening cylinder 12 retracts, so that the cover-fastening cylinder 12 drives the guide rod 16 to drive the edge of the carton cover to open, to complete the cover-opening action; then the cover-fastening cylinder 13 extends, and drives the box-opening cylinder 12 to move downward through the hinge seat 14, and then moves the carton cover downward. After the box-opening cylinder 12 encounters a mechanical limit during its downward movement, the box-opening cylinder 12 tilts and rotates as a whole under the action of the hinge seat 14, and continues to move downward until the box-opening cylinder 12 is separated from the carton cover, thereby realizing the opening and fastening action of the carton cover; it should be noted that, during the downward movement of the carton cover, the clamp arms 8 of the front and rear positioning guide mechanisms 4 and the left and right positioning guide mechanisms 5 guide the carton cover to move downward in the four vertical directions of front, back, left and right.

[0055] After the cover is closed, the cover cylinder 13 drives the cover opening cylinder 12 to reset, and the front and rear positioning guide mechanisms 4, the left and right positioning guide mechanisms 5, and the lifting cylinder 3 are also reset synchronously. The lower box body is moved to the next workstation by the conveyor line 1, and the cover closing action is completed, and preparations are made for the next cover closing.

[0056] The workflow of this application is:

[0057] Assume that the conveyor line 1 has just completed the capping action and is in the starting state.

[0058] 1. The capping cylinder 13 is reset and retracted, and the unpacking cylinder 12 is moved upward. After the capping cylinder 13 has finished its action, the unpacking cylinder 12 is extended to prepare for receiving the materials.

[0059] 2. The upper material distribution cylinder 10 extends and the lower material distribution cylinder 10 retracts, and the top cover of the lowest carton in the silo falls above the opening cylinder 12;

[0060] 3. The opening cylinder 12 is retracted, driving the edge of the carton cover to pull outward to complete the opening action, thus completing the preparation work of the carton cover before buckling;

[0061] 4. After the conveyor line 1 detects that the lower box is in place, the lifting cylinder rises, and the front and rear positioning guide mechanism 4 and the left and right positioning mechanism 5 rise accordingly;

[0062] 5. After the lifting cylinder is in place, the front and rear positioning guide mechanisms 4 and the left and right positioning guide mechanisms 5 are activated simultaneously to complete the preparation for positioning the lower box;

[0063] 6. The cover-fastening cylinder 13 moves downward, driving the carton lower cover on the box-opening cylinder 12 to move downward and fasten the cover;

[0064] 7. When the cover-locking cylinder 13 moves downward and hits the mechanical limit, the unpacking cylinder 12 rotates and tilts to separate from the carton cover;

[0065] 8. The front and rear positioning guide mechanism 4, the left and right positioning guide mechanism 5, and the lifting cylinder are reset to complete the separation of the positioning mechanism and the carton cover;

[0066] 9. The material continues to move forward under the action of the conveyor line 1. After the lower box has passed through, the blocking cylinder rises, the box opening and cover buckling mechanism 6 is retracted and the box is opened, preparing for the next cover buckling action.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
