Description

Technical Field

[0001] The invention relates to the technical field of detonator manufacturing, in particular to a box cover taking and placing device for detonator transportation. Background Art

[0002] Detonators are the main components of civilian explosive equipment, and the base tube in the detonator is one of the main components of the detonator, usually called the "tube shell". The main function of the tube shell is to load the agent to reduce the influence of the agent on the outside world, while increasing the detonation ability and improving vibration safety. At present, most of the civil explosives companies in the industry are operated manually, so that the base tube flows between different production processes to finally obtain the finished detonator, which has a large workload and low efficiency. The base tube needs to be packed and transported in batches before being transferred to the loading device. During transportation, in order to prevent the basic detonator from being exposed to the air for a long time and affecting the quality of the basic detonator, it needs to be placed in a box for sealed storage. When loading, the upper cover of the box should be opened to facilitate loading. When all the basic detonators in the box are loaded to the subsequent process, the box as an empty box needs to be covered again, and then returned to the previous process for the packing and transportation of the next batch of basic detonators. Our company has designed a non-standard system for the unmanned and automated production of detonators. The basic detonators are temporarily stored in the following places: Figure 1 In the box shown in , the box includes two general transport boxes placed side by side with their openings facing upwards, and 12 basic tube temporary storage boxes are arranged in an array in the general transport boxes, so as to meet the mass production efficiency of the entire production line. In order to adapt to the automation and unmanned production of the front-end transportation system, it is necessary to design a device to meet the purpose of manually pushing the basic tube temporary storage box to the loading point, manually removing the box cover, and then manually loading. In addition, there is direct contact between online workers and dangerous goods during the manual loading process. Due to the sensitivity of the medicine, it can be triggered by human static electricity, and when the manual action of taking and placing the box cover is performed, the friction between the clothes and the friction between the clothes and the box cover may generate static electricity, and when the skin touches the box cover, the charge may be released, which is highly dangerous. Summary of the invention

[0003] The present invention provides a device for picking up and placing box covers for detonator transportation, so as to solve the problem that in the existing basic detonator loading automation and unmanned process, the detonators need to be manually picked up and placed before being transported from the automated and unmanned transportation system to the rear loading system.

[0004] To solve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a box-pickup and placement device for transporting detonators, comprising a welding frame, a linear guide rail, a suction cup assembly, and a temporary storage table. The welding frame is a double-layer quadrangular frame, the linear guide rail is located on the top surface of the welding frame, and a suction cup assembly that can reciprocate is slidably connected to the linear guide rail. The suction cup assembly is provided with a plurality of vacuum suction cups corresponding to the temporary storage box of the base tube, and the plurality of vacuum suction cups can move up and down synchronously. The temporary storage table is located on the second layer of the welding frame, and the suction cup assembly is electrically connected to the controller of the peripheral device.

[0005] The basic principle of this scheme is: multiple basic detonators are sealed and stored in the basic tube temporary storage box in the general transport box, and then transported to the designated position under the welding frame of this device through the transportation system of the previous process. When arriving at the designated position, the suction cup assembly moves along the linear guide rail to the top of the basic tube temporary storage box, and multiple vacuum suction cups move down and touch the box cover of the basic tube temporary storage box. The vacuum suction cups are started so that each box cover is adsorbed on the suction cups, and then the multiple vacuum suction cups are moved up, and the vacuum suction cups as a whole drive the box cover to leave the basic tube temporary storage box, and then the vacuum suction cups as a whole are moved horizontally through the linear track and driven to the top of the temporary storage table. After the vacuum suction cups move down, they are inflated and released, and the box cover falls and is placed on the temporary storage table. When all the basic tubes in multiple basic tube temporary storage boxes are loaded, the empty basic tube temporary storage box is transported to the designated position under the welding frame again, and the multiple box covers on the temporary storage table are adsorbed and lifted up by the suction cup again, transferred to the top of the empty box, moved down and released, and the suction cup is dropped back and buckled on the empty box, and then the empty box is returned to the previous process through an external trolley.

[0006] The beneficial effects of this solution are as follows: currently, the basic tube temporary storage box is mostly pushed to the loading position manually, the box cover is manually removed, and then the materials are manually loaded. This solution, after setting up a welding frame, utilizes the reciprocating motion of the suction cup assembly on the welding frame, and the up and down movement of the suction cup to remove the box covers of the basic tube temporary storage box in batches, and places the entire batch on the temporary storage table. After all the basic detonators in the basic tube temporary storage box are loaded, the box covers are placed on the empty box as a whole, thus avoiding the problem of high labor intensity during the loading process, and realizing automatic loading at the node from the transportation process to the loading process. At the same time, by taking the box cover and then putting it into the temporary storage table beside it, instead of continuously hanging the box cover with the suction cup assembly, the mechanical vibration generated by the transportation tools beside the device and the production line where the device is located can be avoided, which can cause relative position error of the box cover after long-term adsorption and inaccurate cover fastening. The box cover can be re-positioned on the temporary storage table, which can not only reduce the aging of the suction cup sealing gasket after the suction cup assembly works under negative pressure for a long time, but also ensure that the suction cup assembly can once again accurately adsorb the temporary storage box of the base tube below when fastening the cover, so as to ensure that the cover fastening work is completed smoothly with high precision.

[0007] Furthermore, the linear guide rails are arranged along the two long sides of the welded frame, and two guide rail sliders are slidably connected on the linear guide rails. The suction cup assembly includes a guide rail chassis, which is frame-shaped, and the guide rail sliders are fixed correspondingly at the four vertices of the guide rail chassis. A horizontal second cylinder is fixedly installed on the welded frame beside the linear guide rail, and the output end of the second cylinder is connected to the guide rail chassis, and the guide rail chassis is driven to reciprocate on the linear guide rail through the extension and contraction of the second cylinder. The guide rail chassis is powered by the second cylinder.

[0008] Furthermore, a vertical first cylinder is fixed on the guide rail chassis, the output end of the first cylinder faces downward and is fixed with a horizontal suction cup fixing plate, a plurality of suction cup mounting plates are arranged at intervals along the length of the suction cup fixing plate, the vacuum suction cup is arranged at intervals on the suction cup mounting plate, the vacuum suction cup is connected to a vacuum switch through a hose, and the vacuum switch is electrically connected to a controller. The vacuum degree of the vacuum suction cup is accurately controlled by the vacuum switch.

[0009] Furthermore, a layer of rubber pad is provided on the temporary storage table surface, and retaining edges are respectively installed on the four sides of the rubber pad surface, and the retaining edges are used to limit the box cover to be taken in and put in. The rubber pad is used to prevent the box cover surface and the temporary storage table from frictionally carrying static electricity.

[0010] Furthermore, two linear bearings are installed on the surface of the guide rail chassis, and two guide rods are symmetrically arranged on both sides of the first cylinder, the guide rods pass through the linear bearings, and the lower ends of the guide rods are fixed on the surface of the suction cup fixing plate. The guide rods are used to enable the entire guide rail chassis to move up and down accurately.

[0011] Furthermore, vertical limit plates are fixed at both ends of each linear guide rail of the welded frame, and a track accordion cover is installed between the two end surfaces of the two guide rail sliders and the limit plates. An accordion cover connecting plate is fixed to the limit plate by bolts, and one end of the track accordion cover is fixed to the side wall of the guide rail slider through the accordion cover connecting plate, and the other end of the track accordion cover is fixed to the limit plate through the accordion cover connecting plate. The stretchable and compressible structure of the accordion cover does not hinder the sliding of the guide rail slider on the guide rail, and at the same time plays the role of covering the surface of the linear guide rail to reduce dust adhesion.

[0012] Furthermore, the first cylinder and the second cylinder are both double-stroke cylinders. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is further described in detail through specific implementation methods:

[0021] The figure marks in the drawings of the specification include: welding frame 1, limit plate 11, linear guide rail 2, guide rail slider 21, track accordion cover 22, accordion cover connecting plate 23, guide rail base frame 3, Y-type joint 31, ear plate 32, guide rod 41, linear bearing 42, first cylinder 43, second cylinder 44, suction cup assembly 5, suction cup fixing plate 51, suction cup mounting plate 52, vacuum suction cup 53, temporary storage table 6, rib 61, rubber pad 62, total transport box 7, base tube temporary storage box 8, box cover 81.

[0022] The embodiment is basically as shown in the attached Figure 1 To Attachment Figure 7 As shown:

[0023] The device for taking and placing box covers for transporting detonators comprises a welding frame 1, which is a double-layer quadrangular frame. Footings are installed at the four vertices of the bottom surface of the quadrangular frame. The footings are used to adjust the horizontality of the entire welding frame 1. A horizontal temporary storage table 6 is installed at half the length of the lower layer of the welding frame 1. An antistatic rubber layer is applied on the surface of the temporary storage table 6. In this embodiment, the antistatic rubber layer is a rubber pad 62. Guard edges 61 are installed on the four sides of the rubber pad 62. The guard edges 61 are used to limit the box cover.

[0024] Linear guide rails 2 are installed on the two long sides of the upper layer of the welded frame 1, and vertical limit plates 11 are fixed on the welded frame 1 where the two end faces of the linear guide rails 2 are located. A number of vertical threaded countersunk holes are spaced along the length of the linear guide rails 2, and threaded blind holes are also opened on the welded frame 1 corresponding to the threaded countersunk holes. Bolts are passed through the threaded countersunk holes and the threaded blind holes to fix the linear guide rails 2 on the welded frame 1 between the limit plates 11. Guide rail sliders 21 are slidably connected to the linear guide rails 2. In this embodiment, two guide rail sliders 21 are slidably connected to each linear guide rail 2. The guide rail sliders 21 on the linear guide rails 2 on both sides form four vertices of a rectangle. A guide rail base frame 3 is fixed horizontally above the guide rail sliders 21. The guide rail base frame 3 is frame-shaped, and the guide rail sliders 21 correspond to the four vertices of the guide rail base frame 3, so that the sliding of the guide rail sliders 21 on the guide rails can drive the entire guide rail base frame 3 to slide.

[0025] A second cylinder 44 is installed on the side of the welding frame 1. The second cylinder 44 is installed parallel to the ground. The output end of the second cylinder 44 is close to the guide rail base frame 3. A Y-type joint 31 is installed on the output end of the second cylinder 44. An ear plate 32 is installed at the lower end of the guide rail base frame 3 corresponding to the Y-type joint 31. After the pin shaft passes through the through holes on the Y-type joint 31 and the ear plate 32 at the same time, the second cylinder 44 is started, and the guide rail base frame 3 can be driven to reciprocate on the welding frame 1 through the extension and retraction of the output end of the second cylinder 44.

[0026] The middle part of the guide rail base frame 3 is connected through a connecting plate, and a vertical first cylinder 43 is fixed on the surface of the connecting plate. In this embodiment, the first cylinder 43 is a double-stroke cylinder, and the output end of the first cylinder 43 extends to the bottom of the connecting plate, and a suction cup fixing plate 51 is fixed on the output end of the double-stroke cylinder. The suction cup fixing plate 51 is in the shape of a long strip and parallel to the two long sides of the welding frame 1. A plurality of suction cup mounting plates 52 are fixed on the bottom surface of the suction cup fixing plate 51 along its length. Each suction cup mounting plate 52 is perpendicular to the suction cup fixing plate 51, and a plurality of vacuum suction cups 53 are symmetrically arranged on the suction cup mounting plate 52. Specifically, the spacing, number of suction cup mounting plates 52 and the number of vacuum suction cups 53 are determined according to the actual number of basic tube temporary storage boxes 8. In this embodiment, there are two total transport boxes 7, and 12 basic tube temporary storage boxes 8 are placed in each total transport box 7. Therefore, a total of 24 vacuum suction cups 53 are arranged, 6 suction cup mounting plates 52, and 4 vacuum suction cups 53 are installed on each suction cup mounting plate 52.

[0027] The vacuum cups 53 are connected to the air source of the external device through hoses, and a vacuum switch is installed on the hose. The vacuum switch is used to automatically measure and control the pressure in the vacuum cups 53. When the vacuum degree generated in actual work reaches the specified requirement, the vacuum switch will automatically open and close the control circuit, send out an electrical signal, and instruct the vacuum component to operate normally.

[0028] In order to ensure that the entire suction cup mounting plate 52 can ensure linear motion under the up and down reciprocating action of the cylinder, vertical guide rods 41 are installed on both sides of the cylinder with the cylinder as the center, and vertical flange linear bearings 42 are installed on the surface of the guide rail base 3. The guide rods 41 pass through the flange linear bearings 42 respectively, and the lower ends of the guide rods 41 are fixed to the surface of the suction cup fixing plate 51.

[0029] On the two opposite ends of the two guide rail sliders 21 on the same side, a track accordion cover 22 is connected between the guide rails. Figure 4 As shown, each elastic unit in the track accordion cover 22 is M-shaped, and a thin layer that can be folded inward is connected between the side walls of the elastic unit, so that the purpose of compression and extension can be achieved. The accordion cover connecting plates 23 are fixed by bolts on the end faces on both sides of the guide rail slider 21 that are far away from each other. The accordion cover connecting plates 23 press one end of the track accordion cover 22 onto the guide rail slider 21, and the other end of the guide accordion cover is also pressed onto the limit plate 11 by the accordion cover connecting plates 23. Two track accordion covers 22 are respectively installed on the same side of the linear guide 2, so as to cover the entire linear guide 2. When the guide rail slider 21 slides back and forth on the linear guide 2, the track accordion covers 22 on both sides are pulled open or compressed accordingly, so that the linear guide 2 can be covered without affecting the sliding of the guide rail slider 21, thereby preventing dust from adhering to the linear guide 2.

[0030] A controller is provided on the side of the welding frame 1, and the controller is electrically connected to the first cylinder 43, the second cylinder 44, the vacuum switch, and the external gas source. The controller is used to fill the vacuum suction cup 53 with the vacuum degree of the external gas source detected by the vacuum switch, control the opening and closing of the external gas source, control the up and down displacement distance of the first cylinder 43, and control the movement of the second cylinder 44.

[0031] The specific implementation process is as follows:

[0032] like Figure 1 , 2As shown, a plurality of temporary storage boxes 8 for basic tubes covered with box covers 81 are loaded in the main transport box 7. When two boxes of main transport boxes 7 are horizontally transported to the bottom of the welding frame 1 by the front-end transport system, 12 temporary storage boxes 8 for basic tubes are placed in each main transport box 7, and there are 24 temporary storage boxes 8 for basic tubes in total. When the main transport box 7 arrives at the designated position, the second cylinder 44 is started, and the second cylinder 44 will push the guide rail chassis 3 to move to the top of the main transport box 7, and then the first cylinder 43 is started, and the output end of the first cylinder 43 is pushed to the top of the main transport box 7. The suction cup mounting plate 52 moves downward, and when each vacuum suction cup 53 simultaneously contacts the top surface of the base tube temporary storage box 8, the external air source is started, and the vacuum degree of the vacuum suction cup 53 is detected by the vacuum switch. After each vacuum suction cup 53 completes the adsorption of each base tube temporary storage box 8, the first cylinder 43 is started again to drive the suction cup mounting plate 52 to move upward, thereby lifting the box cover 81 of each base tube temporary storage box 8, and then the second cylinder 44 is started, and the second cylinder 44 pulls the entire guide rail chassis 3 up. The first cylinder 43 is started again, and the suction cup mounting plate 52 moves down, and in this embodiment, it moves down by 50 mm. Then, the external air source is started to inflate the vacuum suction cup 53, so that multiple box covers 81 are placed on the temporary storage table 6, and the four sides of the multiple box covers are limited by the retaining edge 61 of the temporary storage table 6. Therefore, after all the basic tubes in the subsequent basic tube temporary storage box are loaded, the box covers 81 need to be loaded on the empty box again. The loading process is to start the first cylinder 43 to make the suction cup mounting plate 52 move down by 50 mm. mm, after each suction cup is adsorbed on the box cover accordingly, start the external air source to draw vacuum, after the overall 24 box covers are adsorbed, start the first cylinder 43 to lift, after the 24 box covers are lifted, start the second cylinder 44, pull the guide rail chassis 3 to the top of the empty box, and then start the first cylinder 43 to drive the suction cup mounting plate 52 to move downward as a whole. When the box cover is covered on the empty box, inflate the vacuum suction cup 53, and the box cover can fall on the empty box. The external trolley transports the empty box back to the previous process for packing of the basic tubes.

[0033] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
