Description

Technical Field

[0001] The present invention relates to the field of bag detection, and in particular to an automated performance detection device used for bag production and processing. Background Art

[0002] During the production and processing of luggage, in order to ensure its durability and safety under various conditions of use, it is necessary to conduct various performance tests on the luggage. Among them, the impact resistance test is mainly to evaluate the ability of luggage to resist external impact during use, to ensure that the luggage is subjected to external impact during normal use, and the structure will not be damaged or deformed.

[0003] The existing bag testing standards generally require that the impact block be lifted to a distance of at least one meter from the bag, and then the impact block hits the bag in a free fall manner to test the impact resistance of the bag. However, when testing the impact resistance of the bag in this way, after the impact block hits the bag, the impact block will also be bounced off, resulting in an uncertain falling position of the impact block, which is easy to injure staff or damage related equipment. Moreover, after completing a test, it is necessary to manually find and pick up the impact block, install and reset the impact block, and then perform the impact test again, which consumes a lot of manpower and time, seriously affecting the test efficiency. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, that the impact block is bounced off, which may easily cause personal injury or equipment damage, and that resetting the impact block consumes a lot of manpower and time, and has low detection efficiency, the present invention provides an automated performance testing equipment for luggage production and processing.

[0009] In addition, it is particularly preferred that a clamping plate is further included; a plurality of clamping plates are symmetrically arranged on the impact seat.

[0010] In addition, it is particularly preferred that silicone anti-slip strips are provided on the facing sides of the left and right clamping plates.

[0030] The lifting unit includes an electric guide rail Ⅰ3 and an electric slider Ⅰ4; the vertical beam 2 is installed with the electric guide rail Ⅰ3; the electric guide rail Ⅰ3 is slidably connected with the electric slider Ⅰ4; the electric slider Ⅰ4 is fixedly connected to the suspension beam 5.

[0031] The wire clamping unit includes an electric actuator Ⅰ10 and a limit block 11; two electric actuators Ⅰ10 distributed on the left and right are installed on the fixed seat of the winch 7; the electric actuator Ⅰ10 is an electric push rod; the telescopic parts of all electric actuators Ⅰ10 are commonly fixed to the limit block 11; the lower part of the limit block 11 is in contact with the pull rope 8; the limit block 11 cooperates with the winch 7 to clamp the pull rope 8.

[0032] The lower part of the limit block 11 is made of wear-resistant rubber material, which is used to increase the friction with the pull rope 8 and prevent the pull rope 8 wound on the winch 7 from loosening.

[0033] It also includes a clamping plate 12; two clamping plates 12 are respectively arranged on the left and right parts of the impact seat 1, and all the clamping plates 12 are used to limit the luggage body 001.

[0034] Silicone anti-slip strips are provided on the facing sides of the left and right clamping plates 12 to prevent the bag body 001 from bouncing after being impacted.

[0035] It also includes an electric guide rail Ⅱ101, an electric slider Ⅱ102 and an electric actuator Ⅱ103; the impact seat 1 is equipped with two electric guide rails Ⅱ101 distributed on the left and right; each electric guide rail Ⅱ101 is slidably connected to two electric sliders Ⅱ102; each electric slider Ⅱ102 is equipped with an electric actuator Ⅱ103; the electric actuator Ⅱ103 is an electric push rod; each telescopic part of the electric actuator Ⅱ103 is fixedly connected to a clamping plate 12, which is used to adjust the position of the clamping plate 12, and then adjust the position of the bag body 001.

[0036] It also includes a protective cover 104; two protective covers 104 distributed on the left and right are fixedly connected to the impact seat 1; the protective cover 104 is used to protect the electric guide rail II 101, the electric slider II 102 and the electric actuator II 103 to prevent them from contacting the impact hammer 9.

[0037] The working steps of the above embodiment are:

[0038] First, the external manipulator is controlled to place the bag body 001 on the impact seat 1 and between the four clamps 12. The four clamps 12 limit the position of the bag body 001, effectively avoiding the different positions of the impact hammer 9 when hitting the bag body 001, resulting in large differences in the impact test results of the bag body 001. Then, the electric slider Ⅰ4 is controlled to drive the electromagnet 6 and the impact hammer 9 to move in the up and down directions until the impact hammer 9 is at the height required by the impact detection standard of the bag body 001. Then, the winch 7 is controlled to start and the winch 7 is slowly unwound. Initially, the electromagnet 6 is not energized, and the impact hammer 9 moves slowly downward under the action of gravity, while pulling the pull rope 8 downward until the impact hammer 9 lightly touches the bag body 001. Thus, according to the length of the released pull rope 8, the detection equipment can measure the height of the bag body 001. This ensures that the distance between the upper surface of the bag body 001 and the electromagnet 6 is greater than the height required by the detection standard. Then the winch 7 is controlled to continue to unwind the draw rope 8, so that the draw rope 8 gradually relaxes, and then the winch 7 is controlled to stop, and then the two electric actuators Ⅰ10 are controlled to contract, and the limit block 11 is pressed down synchronously. The limit block 11 cooperates with the winch 7 to clamp the draw rope 8 and lock the draw rope 8, thereby preventing the draw rope 8 wound on the winch 7 from being scattered, and then the electric slider Ⅰ4 is controlled to move downward on the electric guide rail Ⅰ3, and the suspension beam 5 and the corresponding parts thereon are driven downward synchronously until the electromagnet 6 contacts the upper part of the impact hammer 9, and the electromagnet 6 is controlled to start. The electromagnet 6 absorbs the impact hammer 9 made of ferromagnetic material, and then the electric slider Ⅰ4 is controlled to move upward, and the impact hammer 9 is driven upward synchronously, so that the impact hammer 9 reaches the height required by the detection standard. At this time, the draw rope 8 is as shown in FIG. Figure 4As shown in the right figure, it is in a hanging state, and the electromagnet 6 is controlled to be closed. The electromagnet 6 no longer attracts the impact hammer 9, and the impact hammer 9 falls rapidly under the action of gravity. Since the upper part of the through hole 6001 is an arc-shaped chamfer, the friction between the edge of the through hole 6001 and the pull rope 8 is effectively reduced. Therefore, the pull rope 8 is pulled by the impact hammer 9 and quickly passes through the through hole 6001, achieving the effect of free fall of the impact hammer 9, so that the impact hammer 9 hits the bag body 001. The locking of the pull rope 8 by the limit block 11 prevents the impact hammer 9 from being pulled out when it is bounced off, thereby completing an impact resistance test of the bag body 001.

[0039] Taking into account that during the test of the bag body 001, the bag body 001 without any filler is generally tested, so when the impact hammer 9 hits the bag body 001, the bag body 001 is first deformed, and then the deformation is restored, and the impact hammer 9 is simultaneously bounced off. At this time, the drawstring 8 set on the impact hammer 9 can effectively hold the impact hammer 9, and effectively prevent the impact hammer 9 from being bounced off to other positions and accidentally injuring the staff. In order to obtain the impact resistance of the bag body 001, it is generally necessary to repeat the impact test on the bag body 001 several times. Therefore, after completing an impact test of the bag body 001, although the drawstring 8 holds the impact hammer 9, the impact hammer 9 is still in a suspended and swinging state, and the drawstring 8 is initially in a loose hanging state, so that the impact hammer 9 will also contact the adjacent parts during the swinging process. Therefore, protective covers 104 are set on both sides of the impact seat 1. It is used to protect the corresponding parts on the impact seat 1 from damage, and because the upper part of the pull rope 8 is pressed and fixed by the limit block 11, the electric slider Ⅰ4 is controlled to move downward, and the electromagnet 6 is driven to move downward synchronously, and the pull rope 8 at the lower part of the electromagnet 6 is gradually shortened, and the electromagnet 6 gradually approaches the impact hammer 9, so that the impact hammer 9 slowly stops swinging and finally stops on the luggage body 001, and then the electromagnet 6 continues to descend until the electromagnet 6 contacts the impact hammer 9, and the electromagnet 6 is controlled to start, and the electromagnet 6 absorbs the impact hammer 9, and then the electric slider Ⅰ4 is controlled to reset, and the next impact test on the luggage body 001 can be started. Through the above steps, not only the tedious work of frequently retrieving the impact hammer 9 that has completed an impact test and re-fixing it can be avoided, but also the situation that the impact hammer 9 falls and injures the staff or damages related equipment when the impact hammer 9 is bounced off can be avoided. The degree of automation is high and it is convenient to use.

[0040] On the basis of the above work, it is also necessary to consider that when the impact test is carried out on the luggage body 001, the instantaneous impact of the impact hammer 9 on the luggage body 001 and the reaction force of the impact seat 1 on the luggage body 001 will also cause the luggage body 001 to bounce. Therefore, four electric actuators Ⅱ103 are set, so that the position of the clamping plate 12 can be controlled, thereby realizing that the clamping plate 12 can clamp and fix the luggage body 001, and a silicone anti-slip strip is also provided on the clamping plate 12, and the friction between the clamping plate 12 and the luggage body 001 is increased, thereby reducing the bounce amplitude of the luggage body 001 after being hit. If the position of the luggage body 001 is offset after being hit, the electric slider Ⅱ102 is controlled to move on the electric guide rail Ⅱ101, and the electric actuator Ⅱ103 and the corresponding parts thereon are driven to move synchronously, so that the luggage body 001 moves on the impact seat 1 until the luggage body 001 is located at the impact detection position set on the impact seat 1.

[0041] Second embodiment

[0042] On the basis of the first embodiment, according to Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, it also includes a motor 201, a transmission rod 202, a connecting rod 203, a support rod 204, a guide wheel 205 and a strap 206; each protective cover 104 is respectively installed with a motor 201; each motor 201 output shaft is respectively fixedly connected with a transmission rod 202; each transmission rod 202 is rotatably connected to the corresponding protective cover 104 through a connecting block; each transmission rod 202 is respectively fixedly connected with two connecting rods 203 distributed front and back; the two connecting rods 203 on each transmission rod 202 are commonly fixedly connected with a support rod 204; each support rod 204 is rotatably connected with two guide wheels 205 distributed front and back, and the guide wheels 205 can slide on the corresponding support rod 204; the two protective covers 104 are commonly connected with two straps 206 distributed front and back; each strap 206 is wound around two guide wheels 205 opposite to each other on the left and right.

[0043] A plurality of fixing holes 10401 are formed on each protective cover 104 ; the fixing holes 10401 are used to fix the ends of the binding straps 206 .

[0044] The working steps of the above embodiment are:

[0045] On the basis of the first embodiment, the luggage body 001 is limited by the clamping plate 12, and the role of position adjustment is obvious. The luggage body 001 should be fixed by the clamping plate 12 to prevent the luggage body 001 from bouncing after being hit. Even if a silicone anti-slip strip is set on the clamping plate 12, the effect is still limited. At this time, a strap 206 can be set on the luggage body 001. After the external manipulator puts the luggage body 001 to the specified position, due to the size difference of the luggage body 001, the position of the luggage body 001 can be fine-tuned by using the cooperation of the electric slider Ⅱ 102, the electric actuator Ⅱ 103 and the clamping plate 12, so that the luggage body 001 is located at the position to be detected, and then the two motors 201 are controlled to start, and the output shafts of the two motors 201 rotate, synchronously driving the transmission rod 202 and the corresponding parts thereon to rotate. The output shafts of the two motors 201 rotate in opposite directions. From the front to the back, the output shaft of the left motor 201 rotates counterclockwise, and the output shaft of the right motor 201 rotates clockwise. Figure 7 As shown, the upper strap 206 moves toward the bag body 001 until the strap 206 is attached to the bag body 001 and pressed against the bag body 001, thereby fixing the bag body 001 in cooperation with the impact seat 1, thereby preventing the bag body 001 from bouncing violently after being hit, reducing the time for adjusting the position of the bag body 001, and thereby effectively improving the detection efficiency of the impact test on the bag body 001.

[0046] Taking into account the size difference of the luggage body 001, there is a situation where the strap 206 cannot contact and fix the luggage body 001. In this case, a plurality of fixing holes 10401 can be opened on the protective cover 104, and the strap 206 and the protective cover 104 can be fixed by bolts. At this time, the staff only needs to unscrew the fixing bolts of the end of the strap 206 and the protective cover 104, and then move the strap 206 to the top of the luggage body 001 according to the size of the luggage body 001, and then bolt the end of the strap 206 and the protective cover 104 through the fixing holes 10401 to fix the strap 206, thereby achieving impact testing of luggage bodies 001 of different sizes. The structure is simple and the applicability is wide.

[0047] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
