Abstract

The invention discloses a printing roller feeding device. The printing roller feeding device comprises a base, a first mounting part, a first driving part, a second mounting part, a second driving part, a placing table and a third driving part. The guide part is fixedly connected to the equipment to limit the base to only slide in the horizontal transverse direction. When the placing table is in an inclined state, one side away from the second mounting part can touch the ground. And the printing roller is turned to be vertical, the lower end is close to the placing table and touches the ground, and the printing roller is swung to be inclined and propped against the placing table. And the placing table drives the printing roller to be converted into a horizontal state from an inclined state. The base moves horizontally and transversely, the first mounting part moves up and down, and the second mounting part moves horizontally and longitudinally, so that the printing roller is conveyed to a corresponding position and mounted on equipment. And after the printing roller is mounted, the second mounting part is far away from the equipment in the horizontal longitudinal direction, the placement table recovers the inclined state, and the feeding device moves to one side of the equipment in the horizontal transverse direction without interfering with use of the equipment.

Description

Technical Field

[0001] This application relates to printing roller processing and inspection tools, and in particular to a printing roller feeding device. Background Technology

[0002] During the design and manufacturing process, printing rollers need to be installed on various pieces of equipment, such as equipment for scraping adhesive from the roller surface and equipment for checking the coaxiality of the rollers. Generally, tools such as three-jaw chucks, ejector pins, and guide rollers are used to connect the ends of the printing rollers, allowing them to rotate after connection. Currently, the printing rollers are typically removed from the transfer trolley manually and moved to the appropriate installation position on the corresponding equipment. This usually requires multiple people to operate, and the process is relatively complex and labor-intensive. Application content

[0003] This application provides a printing roller feeding device that can solve the problems mentioned in the background art.

[0004] This application provides a printing roller feeding device, comprising: The base has a set of guide wheels for horizontal movement and a guide for mounting to the equipment is slidably connected horizontally. The first mounting part is slidably connected to the base along the vertical axis; The first drive unit is used to drive the first mounting unit to rise and fall; The second mounting part is slidably connected to the first mounting part along the horizontal longitudinal direction; The second drive unit is used to drive the second mounting unit to slide. The placement platform is hinged to the second mounting part around a first horizontal longitudinal axis; limit support blocks are fixedly connected to both sides of the first axis, and the limit support blocks have two support surfaces for supporting the printing roller. The third drive unit is used to drive the placement platform to swing between the following two states: a horizontal state and a tilted state with the side away from the second mounting unit tilted downwards.

[0005] In some embodiments, a backing plate is fixedly connected to the bottom surface of the placement platform. The backing plate has a contact surface, which includes an inclined surface that is inclined relative to the bottom surface of the placement platform and a horizontal surface that is parallel to the bottom surface of the placement platform. The third driving part is a cylinder, the cylinder body is fixedly connected to the second mounting part, and the piston rod is fixedly connected to a blocking member for the contact surface to abut against.

[0006] In some embodiments, the second driving part is a pin-groove pair disposed between the third driving part and the first mounting part, including: a pin connected to the piston rod and a groove rail disposed in the first mounting part.

[0007] In some embodiments, the track includes: a first segment along the horizontal transverse direction and a second segment inclined in the horizontal longitudinal direction; the first segment corresponds to the inclined surface and a portion of the horizontal surface, and the second segment corresponds to the remaining horizontal surface.

[0008] In some embodiments, the first mounting part has an extension on the side away from the placement platform; the extension is fixed with a handle; the valve of the third cylinder is disposed in the extension; and the control switch of the first drive part is disposed in the base.

[0009] In some embodiments, the second mounting part has an abutting surface, and the placement platform abuts against the abutting surface downwards in a horizontal state.

[0010] In some embodiments, the fixed connection between the limiting support block near the second mounting part and the placement platform is adjustable by sliding.

[0011] In summary, this application provides a printing roller feeding device, comprising: a base, a first mounting part, a first driving part, a second mounting part, a second driving part, a placement table, and a third driving part. The base is restricted to sliding only horizontally by a guide member fixedly connected to the equipment. The placement table is tilted, with the side away from the second mounting part touching the ground. The printing roller is flipped to a vertical position, with its lower end near the placement table and touching the ground. The printing roller is then swung, causing it to tilt and be held against the placement table. The placement table, along with the printing roller, transitions from a tilted state to a horizontal state. The base moves horizontally, the first mounting part moves vertically, and the second mounting part moves horizontally, thereby feeding the printing roller to the corresponding position and installing it onto the equipment. After the printing roller is installed, the second mounting part moves horizontally away from the equipment, the placement table returns to its tilted state, and the feeding device moves horizontally to one side of the equipment without interfering with its use. Conversely, the printing roller can also be removed from the equipment via the feeding device. The beneficial effect is that it makes the installation and removal of the printing roller on the equipment more convenient. Attached Figure Description

[0016] Please see Figure 1A printing roller feeding device includes: a base 1, a first mounting part 2, a first driving part 3, a second mounting part 4, a second driving part 5, a placement table 6, and a third driving part 7.

[0017] A guide 1A is slidably connected to the base 1 in a horizontal direction. More specifically, the guide 1A can be a first optical axis, and a linear bearing matching the first optical axis is fixedly connected to the base 1. The guide 1A is used for installation onto the equipment. More specifically, first connecting blocks 1A1 can be fixedly connected to both ends of the first optical axis. By fixing the guide 1A to the equipment, the base 1 is restricted to sliding only in a horizontal direction.

[0018] The base 1 also has a set of guide wheels 1B, which are used for horizontal movement. More specifically, the number of guide wheels 1B can be two, which are symmetrically installed on the vertical outer walls on both sides of the horizontal longitudinal direction of the base 1.

[0019] Please see Figure 1 and Figure 4 The first mounting part 2 is slidably connected to the base 1 along the vertical direction. More specifically, the base 1 can be box-shaped, and one of its vertical side plates can have an upwardly extending first extension plate 1C. The first extension plate 1C is inverted L-shape. A set of second optical axes 1D can be fixedly connected between the horizontal part of the first extension plate 1C and the inner bottom wall of the base 1. The linear bearing matching the second optical axis 1D is fixedly connected to the first mounting part 2.

[0020] The first drive unit 3 is used to drive the first mounting unit 2 to rise and fall. More specifically, the first drive unit 3 may be a double-acting cylinder, with the cylinder as the actuator, a three-position four-way valve as the control switch 3B, and a corresponding air compressor and air circuit, so that the first mounting unit 2 can rise, fall, and stay in the corresponding position.

[0021] Please see Figure 1 and Figure 4 The second mounting part 4 is slidably connected to the first mounting part 2 along the horizontal longitudinal direction. More specifically, the first mounting part 2 may be T-shaped, with the vertical part used for the fixed connection of the linear bearing matching the second optical axis 1D, and the horizontal part may be fixedly connected to a set of third optical axes 2A, with the linear bearing matching the third optical axis 2A fixedly connected to the second mounting part 4.

[0022] The second drive unit 5 is used to drive the second mounting unit 4 to slide. More specifically, the second drive unit 5 can be a rodless cylinder module, and correspondingly, the set of guide rods provided by the rodless cylinder module serves as the aforementioned third optical axis 2A. Referring to the first drive unit 3, which uses a cylinder, the rodless cylinder module also needs to be equipped with a three-position four-way valve, an air compressor, and an air circuit.

[0023] Please see Figure 1 and Figure 3The placement platform 6 is hinged to the second mounting part 4 around the horizontal longitudinal axis.

[0024] The placement platform 6 is fixedly connected to limit support blocks 6A on both sides of the first axis. The limit support blocks 6A have two support surfaces 6A1 for supporting the printing roller. More specifically, both the limit support blocks 6A and the placement platform 6 can be V-shaped, and the two inner sidewalls of the limit support blocks 6A are the two support surfaces 6A1. After the outer wall of the printing roller contacts the two support surfaces 6A1, it supports the printing roller and restricts its rolling.

[0025] Please see Figure 1 and Figure 2 In some embodiments, the fixed connection between the limiting support block 6A near the second mounting part 4 and the placement platform 6 is adjustable by sliding. More specifically, the placement platform 6 may be fixedly connected with two square bars 6B, and the limiting support block 6A may have two first notches 6A2 for the two square bars 6B to enter respectively. The first notches 6A2 may have threaded through holes communicating with themselves, and a hand screw 6A3 may be threadedly connected in the threaded through holes.

[0026] Tighten the two hand-tightened screws 6A3, and the limiting support block 6A will be fixed on the two square bars 6B. Conversely, loosen the two hand-tightened screws 6A3, and the limiting support block 6A can be moved along the square bars 6B.

[0027] The fixed connection position of the limiting support block 6A on the placement table 6 is adjusted to accommodate printing rollers of different lengths.

[0028] Please see Figure 1 and Figure 8 The third drive unit 7 is used to drive the placement platform 6 to swing between two states: a horizontal state and a tilted state with the side away from the second mounting part 4 tilted downwards. More specifically, the third drive unit 7 can be a cylinder or a servo motor.

[0029] Please see Figure 1 and Figure 7 In some embodiments, the second mounting part 4 has an abutting surface 4A, and the placement platform 6 abuts against the abutting surface 4A downward in a horizontal state.

[0030] This ensures that the placement platform 6 remains more stably horizontal.

[0031] Please see Figure 1 , Figure 3 and Figure 4In some embodiments, where the third drive unit 7 is a cylinder, a support plate 6C is fixedly connected to the bottom surface of the placement platform 6. The support plate 6C has a contact surface 6D. The contact surface 6D includes an inclined surface 6D1 that is inclined relative to the bottom surface of the placement platform 6 and a horizontal surface 6D2 that is parallel to the bottom surface of the placement platform 6. The third drive unit 7 is a cylinder, and more specifically, it can be a double-acting cylinder. Referring to the first drive unit 3, which is a cylinder, the third drive unit 7 also needs to be equipped with a three-position four-way valve, an air compressor, and an air circuit.

[0032] The cylinder of the third drive unit 7 is fixedly connected to the second mounting part 4, and the piston rod of the third drive unit 7 is fixedly connected to a blocking member 7C for the contact surface 6D to abut. More specifically, the piston rod of the third drive unit 7 is fixedly connected to a concave second connecting block 7A, and the abutment plate 6C corresponds to the recess of the second connecting block 7A; a set of guide posts 7B is also provided between the second connecting block 7A and the second mounting part 4 to make the second connecting block 7A move more smoothly and to block the contact surface 6D; the blocking member 7C can be a roller, rotatably connected to the second connecting block 7A.

[0033] When the placement platform 6 is tilted, the blocking member 7C contacts the tilted surface 6D1, and the piston rod of the third drive unit 7 is in the retracted position. As the piston rod of the third drive unit 7 extends horizontally: the blocking member 7C gradually moves from the contact position on the tilted surface 6D1 towards the horizontal surface 6D2, causing the placement platform 6 to swing from the tilted state to the horizontal state; when the blocking member 7C contacts the horizontal surface 6D2, the placement platform 6 turns to the horizontal state.

[0034] For further details, please refer to Figure 5 and Figure 6 The second drive unit 5 can also be a slotted pin pair disposed between the third drive unit 7 and the first mounting unit 2. That is, the second drive unit 5 is not a separate power source, but drives the second mounting unit 4 to slide through the cylinder that serves as the third drive unit 7.

[0035] As a pin-and-groove pair, the second drive unit 5 includes: a pin 51 connected to the piston rod and a groove rail 52 disposed on the first mounting part 2. More specifically, the pin 51 is connected at the second connecting block 7A, and the first mounting part 2 is fixedly connected to a second extension plate 2C for mounting the groove rail 52.

[0036] Please see Figure 5 and Figure 7 Furthermore, the channel rail 52 includes: a first segment 521 in the horizontal transverse direction and a second segment 522 inclined in the horizontal longitudinal direction. The first segment 521 corresponds to the inclined surface 6D1 and part of the horizontal surface 6D2, and the second segment 522 corresponds to the remaining horizontal surface 6D2. More specifically, in the top view, the second extension plate 2C has a second notch 2C1 on the side away from the guide member 1A, and the pin 51 is located on the outer side of the placement platform 6 near the guide member 1A.

[0037] When the pin 51 is in the first section 521 of the groove rail 52, the placement platform 6 corresponds to the second notch 2C1 and will not interfere with the placement platform 6 turning into an inclined state. When the pin 51 moves along the first section 521 of the groove rail 52, the placement platform 6 switches between an inclined state and a horizontal state, and at the same time, the second mounting part 4 does not slide and remains corresponding to the second notch 2C1; when the pin 51 moves along the second section 522 of the groove rail 52, the second mounting part 4 slides toward the guide member 1A, and the placement platform 6 remains in a horizontal state.

[0038] Please see Figure 5 Based on the "second drive unit 5 being a slotted pin pair", the first mounting unit 2 has an extension 2B on the side away from the placement platform 6. A handle 2B1 is fixedly mounted on the extension 2B. The valve 7D of the third cylinder is located on the extension 2B; more specifically, this valve 7D can be a hand-cranked valve. The control switch 3B of the first drive unit 3 is located on the base 1. Since the first drive unit 3 is selected to be a cylinder, this control switch 3B can be a foot-operated valve.

[0039] Correspondingly, one hand can hold handle 2B1 to manually move the feeding device horizontally, while the third drive unit 7 is controlled by valve 7D, and the first drive unit 3 is controlled by foot.
