Description

Technical Field

[0001] The present application relates to the field of transfer technology, and in particular to a deviation device and a transfer equipment. Background Art

[0002] With the development of the printing industry, the production demand for products has become increasingly demanding for the automation of printing equipment and the quality of printed products, making the operation of employees simpler and more convenient. This is also the development direction of the industry, towards more automated and simplified equipment. During the printing process of the dry offset roller printing press, it is inevitable that the product will leak when feeding. In the case of leakage, the pattern will be transferred to the carrier carrying the product. After the carrier with the pattern is reloaded with the product, the dry glue on the carrier will be transferred to the inner wall of the product, causing the product to be scrapped.

[0003] The existing method of dealing with material leakage is: after detecting material leakage, the machine alarms, manually fills in the missing barrels of the barrelless mold and then restarts the machine. The machine automatically runs, removes the barrels on the mold, and then continues to print normally. However, this method takes nearly ten minutes and will cause a certain loss of production capacity. At the same time, each time the machine is restarted, the barrel on the mold needs to be removed, which will cause a certain amount of material waste. Utility Model Content

[0055] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0056] Reference Figure 1 , 2As shown, in some embodiments of the present application, a transfer device is provided, including: a deviation device, a loading device and a pad printing device. The loading device is installed on the deviation device, and the pad printing device is arranged on one side of the loading device. The loading device has at least two carrying stations, and the carrying stations are used to carry products. The pad printing device is used to emboss dry glue on the products on the carrying stations. The transfer device is suitable for barrel-shaped packaging box products. Due to its own shape limitation, the carrying station has a mold core that is consistent with the shape of the inner barrel of the product. The barrel-shaped packaging box product is sleeved on the mold core, and the pattern is embossed on the outer surface of the barrel-shaped packaging box product using the pad printing device. If there is a shortage of material in the carrying station, the dry glue will be stained on the mold core. When the mold core stained with dry glue is reloaded with products, the inner barrel wall is easily embossed with dry glue, resulting in product scrapping.

[0057] In this solution, the deviation device includes: a graduation box 1 and a base 2, the graduation box 1 is placed on the base 2, and the graduation box 1 and the base 2 are arranged up and down along the z-axis direction. Specifically, the base 2 includes a shell 21, and the shell 21 has a built-in deviation module 22 and an eccentric shaft 23, and the deviation module 22 drives the eccentric shaft 23 to rotate. The eccentric shaft 23 is stepped, and the eccentric shaft 23 has a connecting section 231 and an eccentric section 232 that are connected to each other, and the diameter of the connecting section 231 is different from the diameter of the eccentric section 232. The axis of the connecting section 231 and the axis of the eccentric section 232 are not on the same straight line, that is, the axis of the connecting section 231 is parallel to the axis of the eccentric section 232 and there is a gap between the two axes.

[0058] The indexing box 1 includes a box body 11 and a sliding plate 14, wherein the sliding plate 14 is connected to the box body 11 and is connected to the eccentric section 232 of the eccentric shaft 23. A first driver 12 is provided on the box body 11, and a mounting shaft 13 as a power output end of the first driver 12 extends out of the box body 11. The loading device is mounted on the mounting shaft 13 extending out of the box body 11. The loading device is rotated by the first driver 12, so that the bearing stations on the loading device are sequentially close to the pad printing device, thereby realizing pad printing patterns on the products in sequence.

[0059] In addition, a leakage detector is provided on one side of the carrying station, or the leakage detector is provided on the pad printing device, and the leakage detector is electrically connected to the offset module 22. The leakage detector detects whether a single carrying station carries a product. When the leakage detector detects that the carrying station does not carry a product, the leakage detector controls the offset module 22 to work. As the offset module 22 works, the eccentric shaft 23 is driven to rotate, so that the sliding plate 14 drives the box body 11 to reciprocate in a straight line direction, so that the indexing box 1 and the loading device are away from the pad printing device, thereby preventing the dry glue from being pad printed to the carrying station by adding a carrying station and a pad printing device.

[0060] After a single pad printing process (material leakage) is completed, assuming that the next carrying station is normally loaded with products, the first driver 12 is actuated to drive the indexing box 1 and the loading device to reset, and the carrying station is again close to the pad printing device, so that the product on the next carrying station can be normally pad printed. If the next carrying station still has material leakage, the offset module 22 can be reset to drive the indexing box 1 and the loading device again, or the indexing box 1 and the loading device can be kept away from the pad printing device.

[0061] In this solution, the leakage detector and the offset module 22 are used to drive the dividing box 1 and the loading device away from the pad printing device to prevent the dry glue from being pad printed to the carrying station; pad printing can still be performed normally after the leakage is processed, and the entire transfer equipment does not need to stop processing the leakage, which greatly improves the efficiency of pad printing.

[0062] At the same time, this solution drives the indexing box 1 and the loading device away from the pad printing device through the offset module 22. Compared with the solution of driving the pad printing device away from the loading device, the pad printing device includes a plurality of color stations and molds. If the color of the pattern is complex, more color stations are required, resulting in a complex structure and a large weight of the pad printing device. If the pad printing device is driven to deviate, the driving force required to be provided by the built-in driving unit of the offset module 22 is large, and the volume of the driving unit and the energy required to be consumed are larger. In the present application, since the volume and weight of the driven indexing box 1 and the loading device are small, the volume of the second driver 221 in the offset module 22 and the energy required to be consumed are smaller, so as to reduce the volume of the entire device and reduce the manufacturing cost and use cost of the device.

[0063] Furthermore, if Figure 5 As shown, the offset module 22 includes a second driver 221, a connecting rod 222 and a pivot seat 223, and the pivot seat 223 is fixedly mounted on the inner wall of the inner cavity of the housing 21. Specifically, the second driver 221 is a cylinder, which is extended and reset by a solenoid valve to convert the forward and backward movement of the cylinder into the rotational movement of the eccentric shaft 23. The fixed end of the second driver 221 is pivotally connected to the pivot seat 223. The power output end of the second driver 221 is connected to one end of the connecting rod 222. The connecting section 231 of the eccentric shaft 23 is connected to the other end of the connecting rod 222. The second driver 221 drives the connecting rod 222 to drive the eccentric shaft 23 to rotate around the axis direction of the connecting section 231.

[0064] A groove is provided on one side of the sliding plate 14 close to the base 2, and the eccentric section 232 is installed in the groove. The rotation of the eccentric section 232 drives the sliding plate 14 to deviate in a straight line direction, and the gap between the axis of the connecting section 231 and the axis of the eccentric section 232 is 0.8-1.5 mm, so that the displacement size of the sliding plate 14 is 0.8-1.5 mm.

[0065] Specifically, the sliding plate 14 includes a body and a mounting block 143, the mounting block 143 is fixedly connected to the body by a first fixing screw 144, and a groove is provided on the mounting block 143. A bearing 26 is also provided between the eccentric section 232 and the groove, and the eccentric section 232 can rotate relative to the sliding plate 14, and the eccentric section 232 can drive the sliding plate 14.

[0066] More specifically, combined with Figure 3 , 4 As shown, the housing 21 has a top 211, the sliding plate 14 is located on the top 211, and a mounting groove 142 is provided on the surface of the sliding plate 14 close to the top 211. A connecting member 15 is installed in the mounting groove 142, and the connecting member 15 is sunk in the mounting groove 142. By providing the connecting member 15, the sliding plate 14 is fixedly connected to the housing 11 to prevent the connecting member 15 from sliding on the top 211, so as to avoid wear between the connecting member 15 and the top 211. Exemplarily, the connecting member 15 is a screw. A fixing hole 111 is provided on the housing 11, and a screw is provided corresponding to the fixing hole 111. The screw passes through the sliding plate 14 and extends into the fixing hole 111, so that the sliding plate 14 is fixedly connected to the housing 21.

[0067] In some embodiments of the present application, reference Figure 6 As shown, two guide modules are installed on the top 211 of the housing 21. The two guide modules are arranged on both sides of the sliding plate 14. The sliding plate 14 slides in a straight line direction in the direction limited by the guide modules. The sliding plate 14 has a guide surface 141 arranged opposite to the guide module. The guide module includes a matching surface of a guide block and the guide surface 141. The moving direction of the sliding plate 14 is limited by the guide module, and the guide module limits the sliding plate 14 from moving in the y-axis direction, so that the sliding plate 14 slides in the x-axis direction.

[0068] Further, the guide module includes a first guide module 24 and a second guide module 25, and the first guide module 24 and the second guide module 25 are arranged at intervals along the y-axis direction. The second guide module 25 includes a second guide block 251 with a matching surface and a second fixing screw 252. The second guide block 251 is fixed to the top 211 by the second fixing screw 252.

[0069] Meanwhile, the first guide module 24 includes a first guide block 241 having a matching surface and an adjustment block 242 . The adjustment block 242 is used to adjust the interval between the first guide block 241 and the second guide block 251 .

[0070] Specifically, the guide surface 141 is inclined at an acute angle relative to the surface of the top 211;

[0071] The angle formed by the mating surface and the surface of the top 211 is not less than the angle formed by the guide surface 141 and the surface of the top 211. For example, the guide surface 141 is arranged parallel to the mating surface, and the sliding plate 14 is restricted from coming out from between the first guide module 24 and the second guide module 25 by the inclined guide surface 141 and the mating surface.

[0072] The above embodiments are used to further illustrate the present application, but the present application is not limited to these specific implementations. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be understood to be within the scope of protection of the present application.
