Description

Technical Field

[0001] This invention relates to the field of luggage caster inlay assembly equipment technology, and particularly to a fully automatic luggage caster inlay assembly equipment and automatic assembly method. Background Technology

[0002] Casters have become an ubiquitous part of everyday transportation tools. There are generally two types of casters: fixed casters and swivel casters. Swivel casters, also known as universal casters, can change the direction of wheel movement at will, making them more convenient and easier to use than fixed casters. As a result, the market demand for swivel casters is increasing, and they are widely used in luggage.

[0003] Currently, there are various shapes and styles of swivel casters on the market, such as the one shown in publication number CN305469259S, where the mounting end face is flat (see...). Figure 1 Or, as shown in publication number CN304831679S, the mounting end face is curved and fits the bag / suitcase (see...). Figure 2 Due to the different shapes of the mounting end faces, the installation methods are inconsistent. Commonly available fully automatic assembly equipment for luggage casters usually cannot meet the automatic assembly requirements of different shapes and styles of movable casters. They can usually only automatically assemble one type of movable caster, which has a small scope of application and high purchase cost. Therefore, companies still prefer to use manual labor to assemble movable casters onto luggage. However, this greatly increases the labor cost and reduces the installation efficiency of luggage casters, which requires improvement. Summary of the Invention

[0004] The primary objective of this invention is to provide a fully automatic inlay and assembly equipment for luggage casters, which has the advantages of wide applicability, low manufacturing cost, reduced labor costs, and increased installation efficiency.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a fully automatic luggage caster mounting and assembly device, comprising a base and a luggage conveyor line fixedly disposed on the base for conveying luggage, and further comprising casters, each caster comprising a mounting part and a rotating part, the mounting part having a plurality of mounting holes; a plurality of luggage straightening mechanisms are evenly disposed along the conveying direction on the luggage conveyor line; a set of caster mounting mechanisms for mounting casters onto luggage is slidably connected to the base along the conveying direction of luggage based on a first opposing sliding mechanism, the caster mounting mechanism comprising a mounting bracket slidably connected to the base, the... One end of the mounting frame near the caster mounting face of the bag is slidably connected to a set of mounting seats based on a second opposing sliding mechanism. The mounting seats are detachably fixed with a caster locking block for locking the caster so that the mounting face of the caster coincides with the mounting face of the bag's caster. The mounting seats are provided with an adjustment mechanism for driving the caster locking block to slide along a direction perpendicular to the mounting face of the caster and driving the caster locking block to rotate a certain angle. At the same time, a screw delivery locking mechanism is fixed in the caster locking block, corresponding to the screw hole on the mounting face of the caster, for locking the caster to the bag with screws after the caster is positioned.

[0006] The present invention is further configured such that: the bag straightening mechanism includes several groups of straightening blocks evenly spaced and fixedly arranged on the bag conveyor line; straightening cylinders are symmetrically fixed on each straightening block in the same group; the telescopic end of the straightening cylinder is fixedly provided with a straightening block for abutting against the side waist of the bag, thereby straightening the bag between the straightening blocks in the same group; one end of the straightening block is fixedly provided with an abutting block for abutting against the caster mounting end face of the bag; and the end of the mounting frame away from the abutting block is fixedly provided with an abutting cylinder for pushing the bag so that the caster mounting end face of the bag abuts against and fits against the abutting block.

[0007] The present invention is further configured such that: the caster locking block includes a locking base, the locking base having a locking groove for locking the swivel portion of the caster, and a locking plate for locking the mounting portion of the caster to prevent the mounting portion from rotating is fixedly provided at one end of the locking base near the caster mounting end face of the bag. The width of the locking groove along the direction perpendicular to the caster mounting end face of the bag is greater than the size of the swivel portion, so that the caster can slide and adjust within the locking groove along the caster mounting end face perpendicular to the bag.

[0008] The present invention is further configured such that the arrangement of the snap-fit ​​plates is adjusted based on the shape of the mounting part of the caster. When the shape of the mounting part of the caster is a planar structure that fits the mounting end face of the bag, the snap-fit ​​plates abut against one or more end faces of the mounting part. When the shape of the mounting part of the caster is an arc surface that fits the curved surface of the bag, the snap-fit ​​plates abut against one or more arc surfaces of the mounting part that are away from the mounting surface.

[0009] The invention is further configured such that: the adjustment mechanism includes a mounting plate rotatably connected to the mounting base; a plurality of mounting guide posts are uniformly fixed on the mounting plate; the caster locking block has mounting guide holes that correspond to and cooperate with the mounting guide posts to achieve quick installation and removal from the mounting plate; a sliding cylinder is fixed on the mounting plate for driving the caster locking block to slide along a direction perpendicular to the mounting end face of the caster; and a rotating adjustment component is fixed on the mounting base for driving the mounting plate to reciprocate 180° to facilitate the screw delivery and locking mechanism to lock the caster onto the bag.

[0010] The present invention is further configured such that: the rotation adjustment assembly includes a rotating gear whose axis coincides with the rotation axis of the mounting plate; a drive motor is fixedly mounted on the mounting base; and a drive gear for driving the rotating gear to rotate is fixedly mounted on the rotation shaft of the drive motor.

[0011] The present invention is further configured such that: one end of the caster locking block is provided with a receiving hole for accommodating and installing the screw conveying and locking mechanism, the receiving hole being staggered with the swivel part of the caster and always corresponding to the mounting hole on the mounting part of the caster.

[0012] The invention is further configured such that: the side end of the mounting frame is slidably connected to an adjusting slide rail fixedly disposed on the mounting frame along the conveying direction perpendicular to the bag conveyor line; the mounting frame is fixedly provided with a third opposing sliding mechanism disposed along the vertical direction; a set of screw conveying and locking mechanisms for locking the side end face of the arc-shaped caster of the mounting part to the bag is slidably connected to the third opposing sliding mechanism; and an adjusting cylinder for driving the mounting frame to slide on the adjusting slide rail is fixedly disposed on the mounting frame.

[0013] The present invention is further configured such that: the first opposing sliding mechanism, the second opposing sliding mechanism and the third opposing sliding mechanism have the same structure, each including a fixed sliding seat and a set of sliding blocks slidably disposed in the sliding seat, a rotating lead screw for driving the sliding blocks to slide in opposite directions is rotatably disposed in the sliding seat, and a lead screw motor for driving the rotating lead screw to rotate is fixedly disposed at one end of the sliding seat, the rotating lead screw being composed of two coaxial lead screws with opposite directions of rotation.

[0014] The second objective of this invention is to provide an automatic assembly method for luggage casters, which has the advantages of wide applicability, low manufacturing cost, reduced labor costs, and increased installation efficiency.

[0015] The above-mentioned technical objective of this invention is achieved through the following technical solution: an automatic assembly method for luggage casters, using a fully automatic luggage caster assembly device as described in any of the above technical solutions, comprising:

[0016] Step 1: Workers place the bags on the bag straightening mechanism of the bag conveyor line. After the bag conveyor line moves the bags to the inlay assembly station, the bag straightening mechanism straightens the bags.

[0017] Step 2: The worker installs the casters into the caster mounting blocks in a specific direction. Then, the first opposing sliding mechanism drives a set of mounting brackets to move in opposite directions, so that the casters move from the side of the bag to the inlay assembly station until the mounting holes on the casters correspond to the screw holes on the mounting end face of the bag's casters.

[0018] Step 3: The screw delivery and locking mechanism fixed in the caster locking block first uses screws to lock one end of the caster mounting part to the caster mounting end face of the bag;

[0019] Step 4: The adjusting mechanism drives the caster locking block to slide outward a certain distance along a direction perpendicular to the caster mounting end face, allowing the caster's swivel part to rotate. Then, the adjusting mechanism drives the caster locking block to rotate the caster locked in the caster locking block at a certain angle, so that the caster's swivel part aligns with the unlocked mounting hole on the caster's mounting part. At the same time, the screw delivery and locking mechanism fixed in the caster locking block also rotates synchronously to the position corresponding to the unlocked mounting hole on the caster's mounting part. At this time, the screw delivery and locking mechanism uses screws to lock and fix the other end of the caster's mounting part to the caster mounting end face of the bag.

[0020] Step 5: After installation, the first opposing sliding mechanism drives a set of installation spans to move to the preparation position, and the bag conveyor line drives the bags with casters installed to the receiving position for receiving.

[0021] In summary, the present invention has the following beneficial effects:

[0022] 1. The caster locking block for locking the casters is detachably and fixedly mounted on the mounting base. When different types of casters need to be installed on the luggage, only the caster locking block fixedly mounted on the mounting base needs to be replaced to adapt to the different types of caster mounting requirements, thus improving the adaptability. At the same time, when installing different types of casters, it is not necessary to replace the entire equipment, but only the caster locking block with low manufacturing cost needs to be replaced, which greatly reduces the manufacturing cost.

[0023] 2. A locking groove for locking the caster is provided on the caster locking block, and a locking plate for locking the caster mounting part is fixedly provided on the locking base. The arrangement of the locking blocks is adjusted based on the shape of the caster mounting part, so that when the caster is installed on the caster locking block, it can be stably locked and positioned, which facilitates the subsequent installation of the caster on the luggage.

[0024] 3. A sliding cylinder is provided on the mounting base to drive the caster locking block to slide along a direction perpendicular to the caster mounting end face, and a rotation adjustment component is provided to drive the mounting plate to rotate 180° reciprocally. Since the swivel portion of common casters often obstructs the mounting holes on the mounting part, it makes it difficult to simultaneously tighten and fix the caster mounting part to the bag with screws. By setting an adjustment mechanism, when the caster is positioned and needs to be fixed with screws, because one end of the caster locking block has a receiving hole that is staggered with the swivel portion of the caster and always corresponds to the mounting hole on the mounting part, the screw delivery and locking mechanism first locks the end of the mounting part that is not obstructed by the swivel portion of the caster, thus initially fixing the caster to the bag. After the initial fixing is completed, the sliding cylinder drives the caster locking block to slide outwards, thus fixing the plate. The snap-fit ​​plate fixed on the snap-fit ​​base can no longer block the installation part of the caster. At this time, the rotating adjustment component drives the caster snap-fit ​​block and the caster snapped in the snap-fit ​​block to rotate 180 degrees, so that the swivel part of the caster rotates to the end of the caster installation part that is initially locked. This causes the screw conveying and locking mechanism to rotate to the position corresponding to the unlocked mounting hole on the installation part of the caster, thereby locking and fixing the other end of the installation part to the bag, ensuring the stability of the caster installed on the bag. At the same time, for casters with curved mounting end faces, locking screws need to be installed on the side. Therefore, a sliding mounting bracket is set on the side of the mounting frame, and an adjustable screw conveying mechanism is set on the mounting bracket to install screws on the side of the caster, thereby ensuring the stability of the caster installation.

[0025] 4. The entire process of installing and assembling the casters requires only a few workers, which reduces the number of workers needed while ensuring installation efficiency and thus lowers labor costs, while increasing installation efficiency. Attached Figure Description

Detailed Implementation

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Example 1:

[0035] refer to Figure 1 and Figure 2 The caster 21 includes a mounting part 211 and a swivel part 212. The swivel part 212 can rotate around the mounting part 211. The mounting parts 211 of the two different casters 21 have different shapes and structures. The mounting part 211 has a flat structure that fits the bottom of the bag 22 and a curved structure that fits the corner of the bag 22. The flat mounting part 211 has four mounting holes 213 evenly provided. The curved mounting part 211 usually has multiple mounting holes 213 evenly provided at the bottom end of the mounting part of the bag 22 and multiple mounting holes 213 also provided at the side end of the bag 22. When the caster 21 is fitted into the bag 22, it can be locked by connecting the mounting holes 213 on the mounting part 211 and the screw holes on the bag 22 with screws.

[0036] refer to Figure 3An automatic assembly and mounting device for luggage casters includes a fixed mounting base 1 and a luggage conveyor line 2 fixedly mounted on the base 1 for conveying luggage 22. The initial end of the luggage conveyor line 2 along the conveying direction of luggage 22 is the loading station of luggage 22, and the end is the unloading station of luggage 22. The mounting and mounting station of luggage 22 is located between the loading station and the unloading station. Several luggage straightening mechanisms 3 are evenly arranged on the luggage conveyor line 2 along the conveying direction for positioning and fixing luggage 22. At the same time, a set of caster mounting mechanisms 4 for mounting casters 21 onto luggage 22 is slidably connected to the base 1 along the conveying direction of luggage 22 based on the first opposing sliding mechanism 5.

[0037] refer to Figure 3 Specifically, the caster mounting mechanism 4 includes a set of mounting brackets 6 slidably connected to the base 1. At one end of the mounting brackets 6 near the caster mounting face of the bag 22, a set of mounting seats 8 is slidably connected to the base 1 based on a second opposing sliding mechanism 7. A caster locking block 9 is fixedly provided on the mounting seat 8 for locking the caster 21, so that the mounting face of the caster 21 coincides with the mounting face of the bag 22. The caster locking block 9 is detachably fixed on the mounting seat 8. Each type of caster locking block 9 is adapted to a corresponding model of caster 21. By changing the model of the caster locking block 9, different models of casters 21 can be fitted. To meet specific requirements, an adjustment mechanism 10 is also fixedly installed on the mounting base 8. The adjustment mechanism 10 is used to drive the caster locking block 9 to slide along a direction perpendicular to the mounting end face of the caster and to drive the caster locking block 9 to rotate a certain angle, thereby realizing the stable locking and fixing of the caster 21 onto the bag 22. At the same time, a screw feeding and locking mechanism is fixedly installed in the caster locking block 9, corresponding to the screw hole on the mounting end face of the caster. After the caster 21 is positioned, a screw feeding and locking mechanism is used to lock the caster 21 onto the bag 22 with screws. The screw feeding and locking mechanism uses a common push-type automatic screwdriver, which can automatically complete the feeding and tightening of screws.

[0038] refer to Figure 3Specifically, the bag straightening mechanism 3 includes several sets of straightening blocks 31 evenly spaced and fixedly arranged on the bag conveyor line 2. Typically, three sets of straightening blocks 31 are arranged on the same side of the bag conveyor line 2. These three sets of straightening blocks 31 are located at the loading station, the inlay assembly station, and the unloading station, respectively. Straightening cylinders 32 are symmetrically fixed on each set of straightening blocks 31. A straightening block 33 is fixedly provided at the telescopic end of the straightening cylinder 32 to abut against the side waist of the bag 22, thereby straightening the bag 22 between the straightening blocks 31 in the same set. Simultaneously, a straightening block 33 is fixedly provided at one end of the straightening block 33 located at the caster mounting face of the bag 22 to abut against the caster mounting face of the bag 22. The abutment block 34 is fixed at the end of the mounting frame 6 away from the abutment block 34. The abutment cylinder 35 is used to push the bag 22 so that the caster mounting end face of the bag 22 abuts against the abutment block 34. When the caster 21 needs to be installed, the alignment cylinder 32 first positions the bag 22 between the alignment blocks 31 in the same group. Then the abutment cylinder 35 abuts against the end of the bag 22 away from the caster mounting end face, thereby pushing the caster mounting end face of the bag 22 to abut against the abutment block 34, thereby realizing the positioning and fixing of the bag 22. Similarly, pads can be attached to the inner side wall of the abutment block 34 to adjust the relative position of the caster mounting end face of the bag 22.

[0039] refer to Figure 3 , Figure 5 and Figure 6Specifically, the caster locking block 9 includes a locking base 91, on which a locking groove 92 is provided for locking the swivel portion 212 of the caster 21. Simultaneously, a locking plate 93 is fixed at one end of the locking base 91 near the caster mounting end face of the bag 22 to lock the mounting portion 211 of the caster 21, thereby preventing the mounting portion 211 from rotating. The inner wall of the locking groove 92 has a certain elasticity. When the worker installs the caster 21 into the locking groove 92, the caster 21... 1. The side wall of the snap-fit ​​groove 92 is pressed. When the caster 21 is placed in the snap-fit ​​groove 92, the inner side wall of the snap-fit ​​groove 92 presses against the side end face of the caster 21, thereby snapping the caster 21 into the snap-fit ​​groove 92. The width of the groove in the snap-fit ​​groove 92 along the direction perpendicular to the caster mounting end face of the bag 22 is greater than the size of the swivel part 212, so that the caster 21 can slide and adjust within the snap-fit ​​groove 92 along the caster mounting end face perpendicular to the bag 22, which facilitates subsequent installation. The arrangement of the snap-fit ​​plates 93 is adjusted based on the shape of the mounting portion 211 of the caster 21. When the shape of the mounting portion 211 of the caster 21 is a planar structure that fits the mounting end face of the bag 22, the snap-fit ​​plates 93 abut against one or more end faces of the mounting portion 211, and the outer end face of the mounting portion 211 is flush with the end face of the snap-fit ​​plate 93 away from the snap-fit ​​base 91. When the shape of the mounting portion 211 of the caster 21 is an arc surface that fits the curved surface of the bag 22, the snap-fit ​​plates 93 abut against the mounting portion 211. 1. One or more arc surfaces away from the mounting surface, and at the same time, the distance between the end face of the snap-fit ​​plate 93 away from the snap-fit ​​base 91 and the end face of the mounting part 211 near the snap-fit ​​base 91 does not exceed the width of the snap-fit ​​groove 92 along the direction perpendicular to the caster mounting end face of the bag 22, which is greater than the width of the swivel part 212. This avoids the snap-fit ​​plate 93 blocking the mounting part 211 of the caster 21 when the adjusting mechanism 10 drives the caster snap-fit ​​block 9 to move outward along the direction perpendicular to the caster mounting end face, thus affecting the normal inlay installation process.

[0040] refer to Figure 3 , Figure 5 and Figure 6Specifically, the adjustment mechanism 10 includes a mounting plate 101 rotatably connected to the mounting base 8. A plurality of mounting guide posts 102 are evenly fixed on the mounting plate 101. The caster locking block 9 is provided with mounting guide holes 94 that correspond to and cooperate with the mounting guide posts 102 to enable quick installation and removal from the mounting plate 101. A sliding cylinder 103 is fixed on the mounting plate 101 for driving the caster locking block 9 to slide in a direction perpendicular to the mounting end face of the caster. At the same time, a rotating adjustment component 104 is fixed on the mounting base 8 for driving the mounting plate 101 to reciprocate 180° so as to facilitate the screw delivery locking mechanism to lock the caster 21 onto the bag 22. The rotation adjustment assembly 104 includes a rotating gear 105 whose axis of rotation coincides with the rotation axis of the mounting plate 101. A drive motor 106 is fixedly mounted on the mounting base 8. A drive gear 107 for driving the rotating gear 105 to rotate is fixedly mounted on the rotation shaft of the drive motor 106. The transmission ratio between the drive gear 107 and the rotating gear 105 is not less than 1:4, thereby increasing the rotational accuracy of the mounting plate 101. A receiving hole 95 for accommodating the mounting screw conveying and locking mechanism is provided at one end of the caster locking block 9. The receiving hole 95 is staggered with the swivel portion 212 of the caster 21 and always corresponds to the mounting hole 213 on the mounting portion 211 of the caster 21. Because the swivel portion 212 of commonly available casters 21 can obstruct the mounting holes 213 on the mounting portion 211, it makes it difficult to simultaneously tighten and fix the mounting portion 211 of the caster 21 onto the bag 22 using screws. By setting an adjustment mechanism 10, when the caster 21 is positioned and needs to be fixed with screws, a receiving hole 95 is provided at one end of the caster locking block 9, which is staggered with the swivel portion 212 of the caster 21 and always corresponds to the mounting holes 213 on the mounting portion 211. First, the screw delivery locking mechanism locks the end of the mounting portion 211 that is not obstructed by the swivel portion 212 of the caster 21, thus initially fixing the caster 21 onto the bag 22. After initial fixing... After the sliding cylinder 103 is completed, it drives the caster locking block 9 to slide outward. The locking plate 93, which is fixed on the locking base 91, can no longer block the mounting part 211 of the caster 21. At this time, the rotation adjustment component 104 drives the caster locking block 9 to rotate the caster 21 locked in the caster locking block 9 by 180 degrees, so that the rotating part 212 of the caster 21 rotates to the end of the mounting part 211 of the caster 21 that is initially locked. This causes the screw conveying locking mechanism to rotate to the position corresponding to the unlocked mounting hole 213 on the mounting part 211 of the caster 21, thereby locking and fixing the other end of the mounting part 211 to the bag 22, ensuring the stability of the caster 21 installed on the bag 22. In this embodiment, the drive motor 106 is a stepper motor, but a servo motor can also be used.

[0041] refer to Figure 3 and Figure 4Specifically, for the caster 21 with an arc-shaped mounting end face, locking screws need to be installed on the side. Therefore, a mounting bracket 13 is slidably connected to the adjusting slide rail 12 fixedly mounted on the side of the mounting frame 6 along the conveying direction perpendicular to the bag conveyor line 2. A third opposing sliding mechanism 14 is fixedly mounted on the mounting bracket 13 along the vertical direction. A set of opposing sliding mechanisms 14 is slidably connected to the third opposing sliding mechanism 14 for mounting the caster 21 with an arc-shaped mounting part 211. The screw delivery and locking mechanism is fixed to the end face of the bag 22. An adjusting cylinder 16 is fixed on the mounting frame 6 to drive the mounting frame 13 to slide on the adjusting slide rail 12. When the caster 21 with the arc-shaped structure of the mounting part 211 is inlaid and assembled onto the bag 22, the adjusting cylinder 16 drives the mounting frame 13 to move to the side end face of the bag 22 to carry out the inlay assembly process. After the installation is completed, the adjusting cylinder 16 drives the mounting frame 13 to return to the initial position to avoid affecting the normal transportation of the bag 22.

[0042] refer to Figure 3 Specifically, the first opposing sliding mechanism 5, the second opposing sliding mechanism 7, and the third opposing sliding mechanism 14 have the same structure. They all include a fixed sliding seat 17 and a set of sliding blocks 18 slidably disposed in the sliding seat 17. A rotating lead screw 19 is rotatably disposed in the sliding seat 17 to drive the sliding blocks 18 to slide in opposite directions. A lead screw motor 20 is fixedly disposed at one end of the sliding seat 17 to drive the rotating lead screw 19 to rotate. The rotating lead screw 19 is composed of two coaxial lead screws with opposite rotation directions. A set of sliding blocks 18 are respectively disposed on the lead screws at both ends. When the lead screw motor 20 drives the rotating lead screw 19 to rotate, the rotation directions of the lead screws at both ends are the same, but the rotation of the pitch is opposite, thereby driving the set of sliding blocks 18 to slide in opposite directions synchronously, which facilitates the positioning of the caster 21.

[0043] Example 2:

[0044] An automatic assembly method for luggage casters 21 (22), used in a fully automatic luggage caster assembly device as shown in Example 1, includes:

[0045] Step 1: The worker places the bag 22 on the bag straightening mechanism 3 of the bag conveyor line 2 at the loading station. After the bag conveyor line 2 moves the bag 22 to the inlay assembly station, the bag straightening mechanism 3 straightens the bag 22.

[0046] Step 2: The worker at the inlay assembly station installs the caster 21 into the caster locking block 9 in a specific direction. Then, the first opposing sliding mechanism 5 drives a set of mounting brackets 6 to move in opposite directions, so that the caster 21 moves from the side of the bag 22 to the inlay assembly station until the mounting hole 213 on the caster 21 corresponds to the screw hole on the caster mounting end face of the bag 22.

[0047] Step 3: The screw conveying and locking mechanism fixed in the caster locking block 9 first uses screws to lock and fix one end of the mounting part 211 of the caster 21 to the caster mounting end face of the bag 22 to complete the initial installation of the caster 21;

[0048] Step 4: The adjusting mechanism 10 drives the caster locking block 9 to slide outward a certain distance away from the bag 22 along a direction perpendicular to the caster mounting end face, so that the swivel part 212 of the caster 21 can rotate. Then, the adjusting mechanism 10 drives the caster locking block 9 to rotate the caster 21 locked in the caster locking block 9 at a certain angle, so that the swivel part 212 of the caster 21 corresponds to the unlocked mounting hole 213 on the mounting part 211 of the caster 21. At the same time, the screw delivery and locking mechanism fixed in the caster locking block 9 also rotates synchronously to the position corresponding to the unlocked mounting hole 213 on the mounting part 211 of the caster 21. At this time, the screw delivery and locking mechanism uses screws to lock and fix the other end of the mounting part 211 of the caster 21 to the caster mounting end face of the bag 22, thus completing the installation of the caster 21.

[0049] Step 5: After installation, the first opposing sliding mechanism 5 drives a set of installation spans 6 to move to the preparation station in opposite directions. At the preparation station, the worker installs the four casters 21 into the caster locking blocks 9 in a specific installation direction. The bag conveyor line 2 then drives the bags 22 with the casters 21 installed to the receiving station for receiving.

[0050] The above-mentioned automatic method for the casters 21 of the bag 22 is mainly for casters 21 with a flat mounting part 211. For casters 21 with a curved mounting part 211, in step 4, the adjusting cylinder 16 will drive the mounting bracket 13 to move to the side end face of the bag 22 and lock the side end face of the mounting part 211 of the caster 21 onto the bag 22 with screws. After the installation is completed, the adjusting cylinder 16 will drive the mounting bracket 13 to return to the initial position.

[0051] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make inventive modifications to this embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
