Description

Technical Field

[0001] The utility model belongs to the technical field of roller packaging, and in particular relates to a spacer for cylindrical roller packaging. Background Art

[0002] At present, cylindrical rollers need to be packed after processing and production to facilitate subsequent transportation. The traditional packing method is to place spacers with a V-groove structure in the packaging box to limit the roller and isolate it from top to bottom. On the one hand, this packaging method is difficult to detect when small debris enters because the cylindrical roller is in line contact with the inner wall of the V-groove on both sides, and foreign matter is easily stuck in the contact line between the spacer and the roller, which causes scratches on the roller surface due to shaking during subsequent production or transportation. On the other hand, since the existing spacer structure is relatively bulky and thick, it can only be stacked layer by layer during storage, resulting in space occupation problems. In addition, when the existing spacers are packed with rollers, the spacers and rollers are placed in the packaging box by manual handling, which is not suitable for production operation environments with a high degree of automation, and has the problems of low loading and unloading efficiency and high labor costs. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the utility model provides a spacer for packaging cylindrical rollers, which has a reasonable design structure and is easy to use. The rollers are stored in an arc-shaped semi-wrapped manner, and a foreign object groove for accommodating debris is arranged in the spacer. When small debris accidentally falls into the packaging box, it can fall into the foreign object groove of the spacer to avoid scratches on the rollers. In addition, the spacer structure can be stacked when stacked, which has the advantage of space occupancy rate, and the diagonal position designed on the surface of the spacer can be easily identified by automated equipment, meeting the needs of automated packaging.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] As shown in the figure, a spacer for cylindrical roller packaging includes an integrally formed spacer body 1, and the spacer body 1 is integrally formed by injection molding.

[0022] The surface of the spacer body 1 is provided with a plurality of roller placement grooves 2 which are arranged at equal intervals and are concave in a circular arc downward. In this example, four rows of roller placement grooves 2 are provided on the surface of the spacer body 1. Each row of roller placement grooves 2 can place an equal number of cylindrical rollers. The cylindrical rollers are placed adjacent to each other end to end on the roller placement grooves 2. In addition, different numbers of roller placement grooves 2 can be designed according to actual needs.

[0023] Each roller placement groove 2 is provided with concave foreign matter grooves 3 at equal intervals along its length direction, that is, the foreign matter grooves 3 are further recessed downward on the basis of the arc-shaped roller placement groove 2. With this arrangement, after the roller is placed on the spacer, the roller can produce a small rolling on the surface of the roller placement groove 2, so that small sundries accidentally dropped into the packaging box fall into the foreign matter groove 3 below, avoiding the risk of scratching the roller.

[0024] The bottom surface of each foreign matter groove 3 is an upwardly protruding arc structure 7, the center line of the arc structure 7 is parallel to the arc center line of the corresponding roller placement groove 2 above, and they are arranged in the same plane in the vertical direction, wherein the highest point of the arc structure 7 is lower than the lowest point of the roller placement groove 2. Such an arrangement can avoid the problem of the arc structure 7 being higher than the lowest point of the roller placement groove 2, causing the bottom of the roller to contact the bottom of the foreign matter groove 3. After the roller is placed, the outer diameter lower surface of the roller contacts the roller placement groove 2 of the lower spacer, and the outer diameter upper surface of the roller contacts the arc structure 7 of the upper spacer, thereby achieving the wrapping and protection effect on the roller, and enabling the upper and lower spacers to have the advantage of neat stacking.

[0025] Focusing positions 4 arranged at equal intervals are provided on the surface of the spacer body 1 between two adjacent roller placement grooves 2. In this example, there are twelve focusing positions 4, which are distributed on the spacer in an array of four rows and three columns. They are mainly used to meet the recognition and focusing of the electronic eyes of automated equipment, thereby determining the position of the spacer, and then meeting the requirements of subsequent automated placement of rollers (suction cups can be used to adsorb the spacer during placement), thereby improving the degree of automation of the packaging process.

[0026] The diagonal position is a blind hole opened on the surface of the spacer body 1, and the outer wall of the blind hole is a conical structure (such as Figure 4 As shown in the surface e), when two spacer bodies 1 are stacked, the outer wall of the blind hole at the upper diagonal position can be placed in the blind hole at the lower diagonal position; more specifically, the outer wall shape of the foreign body groove 3 is an inverted cone structure (such as Figure 3 The surfaces a and b shown in Figure 4 As shown in surfaces c and d), when two spacer bodies 1 are stacked, the outer wall of the upper foreign matter groove 3 can be placed inside the lower foreign matter groove 3. The above arrangement allows the upper and lower adjacent spacers to be stacked in sequence when the spacers are not in use or stored, thereby reducing space occupancy. Furthermore, draft angles are also designed on other vertical surfaces of the spacers to increase space utilization.

[0027] The roller placement groove 2 has ribs 6 at both ends to prevent the rollers from axially moving. The ribs 6 are formed at both ends of the roller placement groove 2 to limit the placed rollers from moving along their axial direction.

[0028] The inner wall of the foreign body groove 3 has ribs 8 protruding toward the center, which are used to increase the overall structural strength of the spacer body 1 to avoid easy damage.

[0029] The upper edge of the spacer body 1 is provided with an upwardly protruding enclosure 5. In this example, the height of the enclosure 5 is 4 mm, and different heights can be designed according to actual needs. The purpose of setting the enclosure 5 is that the roller needs to be sprayed with a layer of anti-rust oil before packaging, and the enclosure 5 can prevent excess anti-rust oil from overflowing.

[0030] The wall thickness of the spacer body 1 is 0.1mm-0.15mm. In the prior art, the thickness of the spacer is 0.5mm, which has the defect of bulky structure. In this example, the thickness of the spacer body 1 is set to 0.1mm-0.15mm, and ribs 8 are designed on the spacer body 1. Under the premise of not affecting the overall structural strength and ensuring safe production and use, the spacer thickness is compressed to the maximum extent, thereby reducing the overall weight of the spacer and reducing the cost.

[0031] In order to realize the automatic adsorption of the septum, a suction cup can be used to adsorb the septum in this example. Specifically, the suction cup can be adsorbed at the position of the foreign matter groove 3 above the septum body 1. When multiple septa are stacked and need to be moved, the upper suction cup structure can contact the first layer of septa, such as Figure 6 As shown, there are four suction cups on the top, which can act on the foreign matter grooves 3 at the four corners of the top of the septum body 1 respectively, and can adsorb and move the top septum to a specified position under the action of negative pressure. In addition, the specific adsorption position can be changed according to the number of suction cups and the distance between the suction cups, and is not limited to the four corners.

[0032] Among them, the gasket is made of PET explosion-proof material as a whole, with a single weight of 15.47g-16.05g. During adsorption, since the suction cup continuously draws a vacuum, the suction cup has a suction force of about 0.5kPa negative pressure per square centimeter, so that when the foreign matter groove 3 of the gasket body 1 is in contact with the suction cup, the adsorption area of ​​the suction cup can be larger than the leakage area around the suction cup, so that the gasket can be adsorbed and the work of moving the gasket can be completed.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
