Description

Technical Field

[0001] The present invention relates to a packaging device, and more particularly to an automatic packaging device for perforating bullets. Background Art

[0002] Perforating charges are explosive devices used to penetrate casing, cement sheaths, and formations during the perforating process. During the perforating charge processing, the glue-coated charges need to be packaged for transportation and storage. Currently, perforating charges are packaged manually, requiring workers to first place baffles, then stack the charges one by one. Once a layer is full, another baffle is added, and the charges are stacked until the desired height of the packaging box is reached. This method is not only inefficient but also labor-intensive. There is also the risk of the charges falling and bumping, causing scratches on the shells and, in extreme cases, explosions that endanger personal safety. Summary of the Invention

DETAILED DESCRIPTION

[0045] See Figure 1-13 As shown, an automatic packaging device for perforating bullets of the present invention includes a frame 1, on which a chain conveyor 2 connected to an external feeding unit is provided, and a number of positioning jigs 3 suitable for the perforating bullets are evenly spaced on the chain conveyor 2. The positioning jigs are preferably made of modified nylon with a static-eliminating function. Of course, other conventional materials with a static-eliminating function in the art can also be used. Perforating bullets may explode due to static electricity, so the discharge of static electricity should be considered. The positioning jigs on the chain conveyor are evenly spaced, and the automated production process is efficient and orderly. This can prevent the perforating bullets from falling and bumping during stacking, and avoid problems such as scratches on the perforating bullet shells or even explosions in extreme cases. Since personnel do not need to participate in the packaging process, even if an explosion occurs, it is not likely to endanger personal safety.

[0046] A transfer platform assembly 4 is installed on the frame 1 at the output end of the chain conveyor 2, parallel to the chain conveyor 2. A stacking mechanism 5 is installed on the frame 1 above the transfer platform assembly 4 and the chain conveyor 2. The perforating charges on the positioning jig 3 are placed on the transfer platform assembly 4 via the stacking mechanism 5. Before packaging, multiple perforating charges are placed on the transfer platform assembly by the stacking mechanism, allowing the automatic material packaging mechanism to place multiple perforating charges at once, improving packaging efficiency.

[0047] A carton conveying line 6 is provided on the frame 1 in front of the output end of the chain conveyor 2 , and the carton conveying line 6 is connected to the output end of the external carton supporting equipment.

[0048] An automatic material packing mechanism 7 is installed on the frame 1 on the other side of the chain conveyor 2. A predetermined number of perforating bullets on the transfer platform assembly 4 are transported by the automatic material packing mechanism 7 to cartons located at predetermined positions on the carton conveyor line 6. An automatic partition feeding mechanism 8 is installed on the frame 1 on the side of the carton conveyor line 6 away from the chain conveyor 2. The partitions are fed into the cartons by the automatic partition feeding mechanism 8 and cooperate with the automatic material packing mechanism 7 to arrange the perforating bullets in a three-dimensional manner inside the cartons.

[0049] A limit clamping mechanism is provided at the position where the carton conveyor line cooperates with the automatic partition feeding mechanism and the automatic material packing mechanism. Corresponding sensors and controllers are provided between the various devices. When the carton is conveyed to the limit clamping mechanism through the carton conveyor line, the limit clamping mechanism pauses and positions the carton, and the automatic partition feeding mechanism and the automatic material packing mechanism respectively place the partition and the perforating bullet into the carton in sequence. The entire packaging process is carried out automatically without the need for workers to participate, thereby reducing the labor intensity of workers.

[0050] The specific structure and connection method of the limit clamping mechanism, sensor and controller are common knowledge to those skilled in the art and will not be described in detail here.

[0051] In this embodiment, the positioning jig 3 comprises a base 3a fixed to the chain conveyor 2. A positioning groove 3b is formed axially on the upper end surface of the base 3a. This groove 3b is in the shape of an inverted truncated cone. The base 3a is removably attached to the chain conveyor via screws. Depending on the outer diameter of the perforating charge being processed, the positioning jig can be replaced with a different positioning groove size to accommodate different perforating charge sizes.

[0052] In this embodiment, preferably, the transfer platform assembly 4 includes a transfer base 4a fixed on the frame 1, and two linear slide rail assemblies 4b of the parallel chain conveyor 2 are arranged on the transfer base 4a, and at least two sliders are arranged on each linear slide rail assembly 4b, and a transfer platform 9 is connected to each slider through a pillar 4c.

[0053] A horizontal transfer servo motor 4d is secured to one end of the transfer base 4a along its length. A screw 4e is connected to the power output shaft of the horizontal transfer servo motor 4d, which is secured to the transfer base 4a via a bearing block. A drive seat 4f, threadedly connected to the screw 4e, is secured to the bottom of the transfer platform 9. The horizontal transfer servo motor and the screw control the position of the transfer platform, ensuring accurate loading of the perforating charges from the stacking mechanism. Controlling the forward and backward movement of the transfer platform and its travel distance using the horizontal transfer servo motor is common knowledge in the art and readily implemented by those skilled in the art, and will not be further elaborated upon here.

[0054] In this embodiment, the coding mechanism 5 includes two mounting vertical plates 5a fixed on the frame 1 and spaced apart, two guide rods 5b are arranged parallel and spaced apart between the mounting vertical plates 5a, a slide 5c is slidably sleeved between the two guide rods 5b, and a horizontal coding cylinder 5d is fixedly connected to one of the mounting vertical plates 5a, and the power output shaft of the horizontal coding cylinder 5d passes through the corresponding mounting vertical plate 5a and is connected to the slide 5c.

[0055] An adjustable lifting cylinder 5e is vertically fixed on the slide 5c, a lifting plate 5f is fixed to the free end of the power output shaft of the adjustable lifting cylinder 5e, and a clamping assembly 10 that cooperates with the positioning fixture 3 and the transfer platform assembly 4 is arranged at an interval at the bottom of the lifting plate 5f; the perforating bullet located on the positioning fixture 3 is transferred to the transfer platform assembly 4 through the clamping assembly 10.

[0056] Preferably, the clamping assembly 10 includes two spaced-apart clamping modules 10a, one of which is connected to a horizontal fine-tuning module 10b; the horizontal fine-tuning module 10b is a fine-tuning cylinder fixed on the lifting plate 5f.

[0057] A large gap is set between adjacent positioning fixtures on the chain conveyor, providing ample clearance for the clamping modules to hold the perforating charges, preventing them from dropping or colliding during stacking. A horizontal fine-tuning module adjusts the spacing between the two clamping modules to accommodate chain conveyors with varying spacing. Synchronous clamping by the two clamping modules effectively improves stacking efficiency.

[0058] The clamping module 10a comprises a clamping cylinder 10c and a clamping block 10d fixed to the two clamping jaws of the clamping cylinder 10c and adapted to the perforating charge. The inner side of the clamping block is a trumpet-shaped opening, which can accommodate multiple perforating charges of different outer diameters.

[0059] Preferably, the transfer platform 9 includes a transfer seat 9a fixedly connected to the support 4c. A transfer plate 9b is fixed to the transfer seat 9a, and a plurality of transfer slots 9c are spaced along the length of the transfer plate 9b. The number of transfer slots 9c is at least two greater than the number of perforating charges that can be transferred in a single operation by the automatic material packing mechanism 7. The transfer plate is removably mounted on the transfer seat, and can be replaced with a transfer plate having different transfer slots depending on the outer diameter of the perforating charge being processed. Furthermore, the transfer plate is preferably made of modified nylon with anti-static properties. Its purpose, like that of the positioning fixture, is to prevent static electricity from causing the perforating charge to explode.

[0060] In this embodiment, the transfer plate is provided with seven transfer slots, and the stacking mechanism completes a cycle with two rounds of placement. During the first round of placement, the stacking mechanism places the perforating charges in positions 1 and 3, then positions 2 and 4, and finally positions 5 and 7. The automatic material packing mechanism then transfers and packs the perforating charges placed in positions 1-5.

[0061] Then the stacking mechanism performs a second round of placement, the first time placing it at positions 4 and 6, the second time placing it at positions 3 and 5, and then the material automatic packing mechanism transports and packs the perforating bullets placed at positions 3-7.

[0062] Due to the large spacing between the two clamping modules, when the perforating charges on the clamping assembly are lowered, there is a certain distance between them, and this distance is usually greater than the spacing between two adjacent perforating charges after packing. By staggered placement, the perforating charges can be placed compactly, which is convenient for subsequent material automatic packing mechanism to carry and pack.

[0063] In this embodiment, the automatic material packing mechanism 7 includes a packing support 7a fixed to the frame 1, a packing manipulator 7b is provided on the packing support 7a, a first mounting seat 7c is fixed to the power shaft at the free end of the packing manipulator 7b, a packing lifting cylinder 7d is provided on the first mounting seat 7c, a second mounting seat 7e is fixed to the free end of the piston rod of the packing lifting cylinder 7d, a positioning plate 7f is fixed to one end edge of the second mounting seat 7e, a clamping cylinder 7g is provided on the inner side of the positioning plate 7f, and a movable clamping plate 7h parallel to the positioning plate 7f is connected to the free end of the piston rod of the clamping cylinder 7g. When the carton is positioned by the limit clamping mechanism, the packing manipulator moves to the top of the carton opening, moves forward, backward, left and right in sequence to push the carton opening outward to ensure that the carton opening is fully opened, and then the automatic partition feeding mechanism places the partition into the carton, and finally the perforating bullet is placed into the carton.

[0064] A positioning clamping seat 7i is installed on the side of the movable clamping plate 7h, located below the clamping cylinder 7g. Positioning notches 7j are provided along the length of the positioning clamping seat 7i to accommodate the perforating charges. A mounting groove is provided on the surface of the positioning plate 7f, opposite the positioning clamping seat 7i. Within the mounting groove is a rubber pad 7k that fits within the positioning notch 7j to clamp the perforating charges. The positioning notches ensure equal spacing between adjacent perforating charges, and the spacing between the positioning notches matches the spacing between the placement slots on the partition. The rubber pad increases the friction of the clamping force, preventing the perforating charges from slipping or falling.

[0065] In this embodiment, the automatic partition feeding mechanism 8 includes a partition conveyor belt 8a provided on the frame 1 and perpendicular to the carton conveyor line 6, and a side baffle 8b is provided on one side of the partition conveyor belt 8a along the partition forward direction.

[0066] A partition lift module 11 is installed on the frame 1 between the partition conveyor belt 8a and the carton conveyor line 6. A partition transfer module 12 is installed on the frame 1 above the partition lift module 11. A positioning mechanism is installed near the upper end of the frame, near the partition lift module and opposite the side guard. When the partition rises to a certain position, the positioning mechanism pushes the partition toward the side guard to position it. After the upper partition is removed by the partition transfer module, the partition lift module raises the partition upward to ensure subsequent placement and removal of the partitions.

[0067] The partition transfer module 12 delivers the partitions on the partition lifting module 11 one by one into the cartons located at predetermined positions on the carton conveying line 6 .

[0068] Preferably, the partition lifting module 11 includes a limit plate 11a fixed vertically on the frame 1, with one side of the limit plate 11a facing the partition conveyor belt 8a. The limit plate blocks and limits the partition group on the partition conveyor belt to ensure that the partition group can be accurately delivered to its proper position.

[0069] A partition lifting support plate 11b is arranged between the limit plate 11a and the partition conveyor belt 8a, and a lifting drive assembly 11c composed of a servo motor, a screw rod and a guide rod is vertically arranged on the back of the limit plate 11a. A lifting seat 11d is movably arranged on the lifting drive assembly 11c, which is threadedly connected to the screw rod and slidably connected to the guide rod.

[0070] Two clearance holes 11e are vertically provided on the limit plate 11a, and two cantilevers opposite to the clearance holes 11e are fixed on the partition lifting support plate 11b. The cantilevers pass through the clearance holes and are fixedly connected to the lifting seat 11d.

[0071] An unpowered transition roller 11f is installed on the frame 1 at the output end of the separator conveyor belt 8a. The separator groups stacked on the separator conveyor belt 8a pass over the transition roller and enter the separator lifting platform 11b. After the separator groups pass through the transition roller, the bottom of the separator groups no longer contacts the separator conveyor belt. At this time, the separator conveyor belt is transported in the opposite direction, moving the next separator group on the separator conveyor belt away from the separator group to be lifted on the separator lifting platform. This prevents interference between the separator groups on the separator lifting platform and the next separator group during the lifting process.

[0072] Further preferably, the partition transfer module 12 includes a transfer support plate 12a fixed on the frame 1, and a horizontal movable seat 12b is connected to the transfer support plate 12a through a guide rod assembly and a stepping screw, and a transfer lifting cylinder 12c is arranged on the horizontal movable seat 12b in the vertical direction, and a transfer seat 12d is connected to the free end of the piston rod of the transfer lifting cylinder 12c, and a transfer support rod 12e is fixed on the transfer seat 12d in the horizontal direction, and an adjustable negative pressure suction cup assembly 12f is sleeved on the transfer support rod 12e, and the negative pressure suction cup assembly 12f is connected to the external negative pressure source pipeline.

[0073] The partition located at the uppermost end of the partition lifting module 11 and reaching a predetermined height is fixed by suction through the negative pressure suction cup assembly 12f and transferred to a carton at a predetermined position on the carton conveyor line 6.

[0074] During operation, the perforating bullets are transported to one end of the transfer platform through the chain conveyor. The horizontal stacking cylinder and the adjustable lifting cylinder move together to enable the clamping module to clamp the perforating bullets and move them above the transfer platform. The horizontal transfer servo motor adjusts the position of the transfer platform to temporarily stack the perforating bullets.

[0075] At the same time, the partition conveyor belt transports the partition group to the partition lifting plate and gradually rises it, and the negative pressure suction cup assembly absorbs the uppermost partition.

[0076] When a carton is delivered to the limit clamping mechanism via the carton conveyor line, it pauses and positions the carton. The packing robot then moves to the top of the carton opening and pushes it outward, moving forward, backward, left, and right to ensure it is fully open. The packing robot then moves to the top of the transfer platform, where the positioning clamping seat and positioning plate cooperate to clamp the perforating charge group on the transfer platform.

[0077] Then the horizontal moving seat cooperates with the transfer lifting cylinder to place the partition into the carton. After the negative pressure suction cup assembly lowers the partition, the horizontal moving seat and the transfer lifting cylinder return to their original positions. Finally, the packing robot moves into the carton and places the perforating bullet group into the placement slots on the partition.

[0078] The above embodiments are preferred implementation modes of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the technical field can, without departing from the scope of the technical features of the present invention, make partial changes or modifications to the technical contents disclosed in the present invention and make equivalent embodiments without departing from the technical features of the present invention. Such modifications still fall within the scope of the technical features of the present invention.
